Description

A device for conveying materials to a high working position

Technical Field

The utility model relates to the technical field of material lifting equipment, and more specifically, to a device for conveying materials to a high working position.

Background technique

The material conveying system for automobile assembly is generally composed of an SPS sorting system and a material traction system. The parts required for automobile assembly are sorted by the SPS sorting system in the SPS sorting area and loaded into the material rack. An AGV trolley is installed at the bottom of the material rack. Under the guidance of the AGV material traction system, the AGV trolley transports the material rack and the material to the assembly line. In the existing assembly workshop, the assembly line platform is generally higher than the AGV trolley transportation road surface. Therefore, when the material is delivered to the assembly line by the AGV trolley, it is necessary to manually pick up the material rack and put it on the material platen before using the material. The process is labor-intensive and has low work efficiency. There is a height difference between the assembly line platform and the transportation road surface, and workers are prone to fall onto the road surface when carrying. Generally speaking, this problem can be solved by setting a slope next to the assembly line. However, for some handling AGV trolleys, the climbing angle is generally not large. Usually, they can only climb slopes with a slope of less than 10 degrees, and materials are prone to dumping when climbing. Therefore, it is not appropriate to set a slope.

In the prior art, a material lifting device includes: a mobile chassis; a fixed gantry, which is vertically arranged on the mobile chassis; a lifting gantry, which is slidably arranged along the length direction of the fixed gantry; a material bracket, which is vertically slidably arranged on the lifting gantry and parallel to the mobile chassis; a power control system, which includes a control box arranged on one side of the fixed gantry, a hydraulic cylinder connected to the control box, and the hydraulic cylinder is connected between the bottom end of the fixed gantry and the top end of the lifting gantry; the power control system also includes a chain guide mechanism for driving the lifting operation of the material bracket, the chain guide mechanism is arranged within the fixed gantry and the lifting gantry and distributed on both sides of the hydraulic cylinder, and the chain guide mechanism on each side includes a sprocket arranged on the top end of the lifting gantry, a chain meshed and connected to the sprocket, the first end of the chain is connected to the material bracket, and the second end of the chain is connected to the upper end of the fixed gantry. The present invention saves time and labor, has low lifting difficulty, is stable, has high lifting efficiency, and has high reliability and safety. However, when the device is used in an automobile assembly workshop, it occupies a large area, which will affect normal production work. In addition, when the materials are lifted, they need to be lifted together with the AGV cart. After the AGV cart moves the material rack out, the material rack needs to be lifted manually to separate the AGV cart and the material rack from each other. Only then can the AGV cart be returned to the device and then lowered to the transport road. The process also requires manual intervention, which has limitations and is not suitable for automobile assembly workshops.

Utility Model Content

The utility model provides a device for conveying materials to a high workstation in order to overcome the defects of the prior art that lifting materials in an assembly workshop consumes manpower and has low efficiency.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a device for conveying materials to a high workstation, comprising: a track bracket, a first moving component slidably connected to the track bracket, a lifting component connected to the first moving component, and a clamping component arranged at the bottom of the lifting component; the clamping component comprises a clamping bracket, a clamping rod slidably connected to the clamping bracket, and a first driving unit connected to the clamping rod and driving the clamping rod to slide along the clamping bracket.

In this solution, the first moving component moves relative to the track bracket, the lifting component is connected to the first moving component and causes the clamping component to lift and lower, and the clamping component is used to clamp the material rack. During use, the lifting component descends below the material rack, and the first moving component brings the lifting component and the clamping component close to the material rack, and causes the clamping bracket and the clamping rod to extend into the bottom of the material rack. Then the lifting component brings the clamping component up so that the clamping bracket contacts the bottom of the material rack, and the lifting component stops moving. The first driving unit drives the clamping rod to retract and clamp the bottom of the material rack. The lifting component starts again, and after the clamping component and the material rack are raised to the set position, the first moving component The parts move, driving the lifting component, the clamping component and the material rack to the set position next to the assembly line, and then stop moving. After the lifting component makes the clamping component and the material rack drop to the ground of the assembly line platform, the first drive unit drives the clamping rod to extend, releases the material rack, and the lifting component makes the clamping component drop. The first moving component drives the lifting component and the clamping component to move, and then each component resets and waits for the next work. In this way, the material can be automatically lifted along with the material rack, improving work efficiency. During the process, there is no need for staff to carry or lift the material rack, nor is there any need to lift the AGV trolley to the ground of the assembly line platform, and the work efficiency of the AGV trolley is also guaranteed. At the same time, the track bracket in this scheme is located at the top of the device, and the remaining components or parts are suspended on the track bracket. In actual use, the track bracket is set above the workbench, which occupies less ground space and will not affect the existing workshop work, which is more practical.

In addition, the clamping rod is not a smooth rod. A protruding block is provided at the end away from the clamping bracket to play a clamping role. The clamping rod can be directly set as an L rod, or a clamping plate or clamping block protruding from the clamping rod body can be installed at the end of the clamping rod. The specific shape of the clamping rod can also be reasonably set according to the bottom of the material rack to ensure a stable clamping effect.

Preferably, the track bracket includes two track beams parallel to each other and fixed beams arranged at both ends of the track beams, the track beams and the fixed beams are connected in sequence to form a rectangular bracket, and both ends of the first movable component are connected to the track beams.

The track beam is used to connect the first moving component, and the fixed beam is used to fix the two ends of the track beam so that the two track beams are stable and remain relatively parallel to avoid affecting the movement of the track beams.

Preferably, the first moving component includes a first cross bar, a first connecting plate arranged at both ends of the first cross bar, a roller rotatably mounted on the first connecting plate, and a second driving unit arranged at one end of the first cross bar; a first guide rail serving as a moving track for the roller is provided on the track beam, a first rack is provided on a side of the track beam close to the second driving unit, and the second driving unit is connected to the first rack through a gear.

The second driving unit is fixedly connected to the first cross bar and is connected to a gear. When the second driving unit drives the gear to rotate, the gear rolls on the first rack, thereby driving the first moving assembly to move. During the movement, the roller slides relative to the first guide rail to bear the gravity of each component, namely the material, and changes the sliding friction into rolling friction to reduce the movement resistance. The top and bottom of the beam are provided with first guide rails. The top rail is used to bear pressure, and the bottom rail is used to assist the movement of the first moving assembly to play a guiding role and prevent deviation. At the same time, a single first connecting plate is also provided with multiple rollers that are respectively connected to the first guide rails on the upper and lower sides, and at the same time share the gravity to reduce the pressure borne by a single roller.

Preferably, a second movable assembly is provided on the side of the first cross bar, and the second movable assembly includes a third driving unit, a second connecting plate connected to the third driving unit, and a slider rotatably mounted on the second connecting plate; a second guide rail serving as a moving track for the slider is provided on the first cross bar, and a second rack is provided on the side of the first cross bar close to the third driving unit, and the third driving unit is connected to the second rack through a gear.

The second moving assembly can move on the first crossbar, increasing the degree of freedom of the device, and can make better adjustments to the placement of the material rack to better meet the use requirements. The third driving unit drives the gear to move the second moving assembly relative to the rack, thereby achieving relative movement with the first crossbar. In the second moving assembly, the second connecting plate is used to connect the components, the slider is used to reduce the movement resistance, and the second guide rail is used to guide the slider.

Preferably, the first guide rail is a V-shaped guide rail, and the roller is a V-shaped roller.

The first guide rail needs to bear the weight of the first moving component, lifting component, clamping component, material rack and material, etc. The load it bears is very large. The use of V-shaped guide rails can alleviate the load problem of the guide rails themselves. The V-shaped guide rails have multiple anti-bending and anti-torsion designs, and have higher rigidity. They can withstand larger axial and radial loads and provide a stable working platform. V-shaped rollers are used in conjunction with them.

Preferably, the lifting assembly includes a mounting plate connected to the second connecting plate, a fourth driving unit connected to the mounting plate, a first gear connected to the fourth driving unit, a third rack meshing with the first gear, and a vertical rod connected to the rack; the bottom end of the vertical rod is connected to the clamping assembly.

In the lifting assembly, the fourth driving unit drives the first gear to rotate, thereby causing it to roll relative to the third rack, thereby driving the entire lifting assembly to lift. The third rack is arranged on the vertical rod, and the mounting plate is also arranged on the vertical rod. At the same time, a clamping assembly is connected to the bottom end of the vertical rod. When the lifting assembly is lifted or lowered, the clamping assembly is driven to lift or lower.

Preferably, a rotating assembly is provided between the bottom of the vertical rod and the clamping assembly, and a third connecting plate is also provided at the bottom of the vertical rod. The rotating assembly includes a fifth driving unit connected to the third connecting plate, a second gear connected to the fifth driving unit, a third gear meshing with the second gear, and a dustproof shell connected to the third connecting plate; a connecting rod is connected to the top of the clamping bracket, the connecting rod is hinged to the third connecting plate, and the third gear is connected to the connecting rod.

The setting of the rotating assembly can further increase the degree of freedom of the device. Before the setting of the rotating assembly, the device can only lift and lower the material rack, and cannot rotate the angle. The walking route of the AGV trolley needs to be set according to the final placement angle of the material rack, which is quite restrictive. After the setting of the rotating assembly, this problem can be well solved, reducing the walking route requirements of the AGV trolley and reducing the site layout cost. In the rotating assembly, the fifth drive unit is fixedly set on the third connecting plate, and then drives the second gear to drive the third gear. The third gear is fixedly connected to the connecting rod, and the connecting rod drives the clamping assembly to rotate. The dustproof shell is connected to the third connecting plate and surrounds the second gear and the third gear to play a protective role. One end of the connecting rod is hinged to the third connecting plate and is also provided with a limit structure to prevent the connecting rod from falling. The other end is fixedly connected to the clamping bracket. The connecting rod not only connects the clamping assembly with the third connecting plate, but also acts as a rotating shaft. There can be many specific structures of the connecting rod and the third connecting plate. For example, a circular hole is set on the third connecting plate. After the top end of the connecting rod passes through the circular hole, a limiting protrusion is installed on the top end of the connecting rod. The limiting protrusion abuts against the third connecting plate to prevent the connecting rod from falling. At the same time, a radial bearing can be set between the limiting protrusion and the third connecting plate to reduce friction.

Preferably, a plurality of photoelectric switches are provided on the track crossbeam.

The device has many operating states during operation, such as stopping, low-speed movement, high-speed movement, waiting, and material picking. Multiple photoelectric switches are arranged on the track beam. The photoelectric switches are arranged in sequence along the moving direction of the first moving component to divide the track beam into multiple areas. When the first moving component contacts the photoelectric switches at different positions, the moving state or moving speed is changed to meet different operating requirements.

Preferably, an I-shaped steel is connected above the track crossbeam.

I-shaped steel is arranged above the track beam, and multiple connections are arranged between the track beam and the I-shaped steel, which can share the tension on the track beam and increase the overall pulling strength of the device.

Preferably, the track crossbeam, the first crossbar and the vertical bar are all provided with limit blocks and limit switch assemblies.

The track beam, the first crossbar and the vertical bar are all slidably connected with movable components. Limit blocks can be set to prevent the movable components from moving excessively. The limit component switch can be connected to the power supply and alarm of the drive unit. When the component moves excessively, the power supply can be cut off and the alarm can be sounded in time.

Compared with the prior art, the beneficial effects are:

The track bracket is set above the workbench, and the other components and parts are suspended below the track bracket, which reduces the occupancy of the ground space and is more suitable for workshops; at the same time, the clamping component is used to clamp the material rack, the material rack is used to place materials, and the lifting component is used to lift the materials, and then the materials are moved to the designated position through the first moving component, thereby completing the automatic lifting of the materials, saving work efficiency and labor.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

The technical solution of the utility model is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

Example 1

As shown in Figures 1-3, a device for conveying materials to a high workstation includes: a track bracket 1, a first moving component 2 slidably connected to the track bracket 1, a lifting component 3 connected to the first moving component 2, and a clamping component 4 arranged at the bottom of the lifting component 3; the track bracket 1 is arranged above the working platform, and the clamping component 4 includes a clamping bracket 401, a clamping rod 402 slidably connected to the clamping bracket 401, and a first driving unit 403 connected to the clamping rod 402.

In this solution, the first moving component 2 moves relative to the track bracket 1, the lifting component 3 is connected to the first moving component 2 and causes the clamping component 4 to lift and lower, and the clamping component 4 is used to clamp the material rack. During use, the lifting component 3 descends to the bottom of the material rack, and the first moving component 2 brings the lifting component 3 and the clamping component 4 close to the material rack, and causes the clamping bracket 401 and the clamping rod 402 to extend into the bottom of the material rack. Then, the lifting component 3 rises with the clamping component 4, and after the clamping bracket 401 contacts the bottom of the material rack, the lifting component 3 stops moving, and the first driving unit 403 drives the clamping rod 402 to retract and clamp the bottom of the material rack. The lifting component 3 starts again, and lifts the clamping component 4 and the material rack to the set position. After that, the first moving component 2 moves, driving the lifting component 3, the clamping component 4 and the material rack to the set position next to the assembly line, and then stops moving. After the lifting component 3 makes the clamping component 4 and the material rack descend to the ground of the assembly line platform, the first driving unit 403 drives the clamping rod 402 to extend, releases the material rack, and the lifting component 3 makes the clamping component 4 descend. The first moving component 2 drives the lifting component 3 and the clamping component 4 to move again, and then each component is reset and waits for the next work. In this way, the material can be automatically lifted with the material rack, improving work efficiency. The process does not require staff to carry or lift the material rack, nor does it require the AGV trolley to be lifted to the ground of the assembly line platform, and the work efficiency of the AGV trolley is also guaranteed. At the same time, the track bracket 1 in this scheme is located at the top of the device, and the remaining components or parts are suspended on the track bracket 1. In actual use, the track bracket 1 is set above the workbench, and the ground space is small, which will not affect the existing workshop work and is more practical.

In addition, the clamping rod 402 is not a smooth rod, and a protruding block is provided at the end thereof away from the clamping bracket 401 to play a clamping role. The clamping rod 402 can be directly set as an L rod, or a clamping plate or a clamping block protruding from the rod body of the clamping rod 402 can be installed at the end of the clamping rod 402. The specific shape of the clamping rod 402 can also be reasonably set according to the bottom of the material rack so that the clamping effect is stable. In this embodiment, the first driving unit 403 only needs to drive the clamping rod 402 to perform the clamping action, and a cylinder can be used as a driving member to reduce costs.

The beneficial effects of this embodiment are as follows: the track bracket 1 is arranged above the workbench, and the remaining components and parts are suspended below the track bracket 1, which reduces the occupancy of the ground space and is more suitable for workshops; at the same time, the clamping component 4 is used to clamp the material rack, the material rack is used to place materials, the lifting component 3 is used to lift the materials, and then the materials are moved to the specified position through the first moving component 2, thereby completing the automatic lifting of the materials, saving work efficiency and labor.

Example 2

As shown in FIG1-8, based on Example 1, the difference from Example 1 is that:

The track bracket 1 includes two track beams 101 parallel to each other and fixed beams 102 arranged at both ends of the track beams 101. The track beams 101 and the fixed beams 102 are connected in sequence to form a rectangular bracket, and both ends of the first moving component 2 are connected to the track beams 101. The first moving component 2 includes a first crossbar 201, a first connecting plate 202 arranged at both ends of the first crossbar 201, a roller 203 rotatably mounted on the first connecting plate 202, and a second driving unit 204 arranged at one end of the first crossbar 201; the track beam 101 is provided with a first guide rail 103 as a moving track of the roller 203, and a first rack 104 is provided on one side of the track beam 101 close to the second driving unit 204, and the second driving unit 204 is connected to the first rack 104 through a gear. A second moving assembly 5 is provided on the side of the first crossbar 201, and the second moving assembly 5 includes a third driving unit 501, a second connecting plate 502 connected to the third driving unit 501, and a slider 503 rotatably mounted on the second connecting plate 502; a second guide rail 2011 is provided on the first crossbar 201 as a moving track for the slider 503, and a second rack 2012 is provided on the side of the first crossbar 201 close to the third driving unit 501, and the third driving unit 501 is connected to the second rack 2012 through a gear. The first guide rail 103 is a V-shaped guide rail, and the roller 203 is a V-shaped roller.

The track beam 101 is used to connect the first moving assembly 2, and the fixed beam 102 is used to fix the two ends of the track beam 101, so that the two track beams 101 are stable and relatively parallel to avoid affecting the movement of the track beam 101. The second driving unit 204 is fixedly connected to the first crossbar 201 and is connected to a gear. When the second driving unit 204 drives the gear to rotate, the gear rolls on the first rack 104, thereby driving the first moving assembly 2 to move. During the movement, the roller 203 slides relative to the first guide rail 103 to bear the gravity of each component, that is, the material, and the sliding friction is changed to rolling friction to reduce the movement resistance. The top and bottom of the beam are provided with a first guide rail 103, the top rail is used to bear pressure, and the bottom rail is used to assist the movement of the first moving assembly 2, play a guiding role, and prevent deviation. At the same time, a single first connecting plate 202 is also provided with multiple rollers 203 respectively connected to the upper and lower first guide rails 103, and at the same time share the gravity, reducing the pressure borne by a single roller 203. The second moving assembly 5 can move on the first crossbar 201, increasing the degree of freedom of the device, and can make better adjustments to the placement of the material rack, so as to better meet the use requirements. The third driving unit 501 drives the gear to move the second moving assembly 5 relative to the rack, thereby achieving relative movement with the first crossbar 201. In the second moving assembly 5, the second connecting plate 502 is used to connect the various components, the slider 503 is used to reduce the movement resistance, and the second guide rail 2011 is used to guide the slider 503. The first guide rail 103 needs to bear the weight of the first moving assembly 2, the lifting assembly 3, the clamping assembly 4, the material rack and the material, etc., and the load it bears is very large. The use of a V-shaped guide rail can alleviate the load problem of the guide rail itself. The V-shaped guide rail has a higher rigidity through multiple anti-bending and anti-torsion designs, can withstand larger axial and radial loads, and can provide a stable working platform. The V-shaped roller is used in conjunction with it.

In this embodiment, the first moving assembly 2 and the second moving assembly 5 need to be precisely positioned, and the second driving unit 204 and the third driving unit 501 are driven by motors and then precisely controlled by PLC.

The remaining features and working principles of this embodiment are consistent with those of Embodiment 1.

Example 3

As shown in FIG. 1-8, on the basis of Example 1 or Example 2, Example 1 or Example 2 is further limited, and the difference is that:

The lifting assembly 3 includes a mounting plate 301 connected to the second connecting plate 502, a fourth driving unit 302 connected to the mounting plate 301, a first gear 303 connected to the fourth driving unit 302, a third rack 304 meshed with the first gear 303, and a vertical rod 305 connected to the rack; the bottom end of the vertical rod 305 is connected to the clamping assembly 4. A rotating assembly 6 is provided between the bottom of the vertical rod 305 and the clamping assembly 4, and the rotating assembly 6 includes a dustproof housing 601 connected to the bottom of the vertical rod 305, a fifth driving unit 602 connected to the dustproof housing 601, a second gear 603 connected to the fifth driving unit 602, and a third gear 604 meshed with the second gear 603; the third gear 604 is connected to the clamping assembly 4. A plurality of photoelectric switches 7 are provided on the track beam 101. An I-shaped steel 8 is connected above the track beam 101. Limit blocks 9 and limit switch assemblies 10 are provided on the track beam 101, the first crossbar 201 and the vertical rod 305.

In the lifting assembly 3, the fourth driving unit 302 drives the first gear 303 to rotate, thereby causing it to roll relative to the third rack 304, thereby driving the entire lifting assembly 3 to be lifted and lowered. The third rack 304 is arranged on the vertical rod 305, and the mounting plate 301 is also arranged on the vertical rod 305. At the same time, the bottom end of the vertical rod 305 is connected to the clamping assembly 4, and the lifting assembly 3 drives the clamping assembly 4 to be lifted and lowered when it is lifted and lowered. Setting the rotating assembly 6 can further increase the degree of freedom of the device. Before setting the rotating assembly 6, the device can only lift and lower the material rack, and cannot rotate the angle. The walking route of the AGV trolley needs to be set according to the final placement angle of the material rack, which is relatively restrictive. After setting the rotating assembly 6, this problem can be well solved, reducing the walking route requirements of the AGV trolley and reducing the site layout cost. In the rotating assembly 6, the fifth driving unit 602 is fixedly arranged on the third connecting plate 3051, and then drives the second gear 603 to drive the third gear 604, the third gear 604 is fixedly connected to the connecting rod, and the connecting rod drives the clamping assembly 4 to rotate, and the dustproof housing 601 is connected to the third connecting plate 3051 and surrounds the second gear 603 and the third gear 604 to play a protective role. One end of the connecting rod is hinged to the third connecting plate 3051 and is also provided with a limiting structure to prevent the connecting rod from falling, and the other end is fixedly connected to the clamping bracket 401. The connecting rod not only plays the role of connecting the clamping assembly 4 and the third connecting plate 3051, but also plays the role of a rotating shaft. There can be many specific structures of the connecting rod and the third connecting plate 3051. For example, a circular hole is set on the third connecting plate 3051. After the top of the connecting rod passes through the circular hole, a limiting protrusion is installed on the top of the connecting rod. The limiting protrusion abuts against the third connecting plate 3051 to prevent the connecting rod from falling. At the same time, a radial bearing can be set between the limiting protrusion and the third connecting plate 3051 to reduce friction. In this embodiment, the connecting rod is located at the axis of the third gear 604 and is blocked by the third gear 604. This part is not shown in the figure. There are many operating states in the device during work, such as stopping, low-speed movement, high-speed movement, waiting, and material collection. A plurality of photoelectric switches 7 are set on the track beam 101. The photoelectric switches 7 are sequentially set along the moving direction of the first moving component 2 to divide the track beam 101 into multiple areas. When the first moving component 2 contacts the photoelectric switches 7 at different positions, the moving state or moving speed is changed to meet different operation requirements. I-shaped steel 8 is arranged above the track beam 101, and multiple connections are arranged between the track beam 101 and the I-shaped steel 8, which is used to share the tension on the track beam 101 and increase the overall pulling strength of the device. The track beam 101, the first crossbar 201 and the vertical bar 305 are all slidably connected with movable components. The limit block 9 can prevent the movable components from moving excessively. The limit component switch can be connected to the power supply and alarm of the drive unit. After the component moves excessively, the power supply can be cut off and the alarm can be sounded in time.

In this embodiment, the fourth driving unit 302 and the fifth driving unit 602 are driven by motors and are also precisely controlled by PLC.

The rest of the working principle and working process of this embodiment are consistent with those of Embodiment 1 or Embodiment 2.

Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
