Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and fig. 6, a feeding device according to an embodiment of the present invention includes a driving mechanism 10 and a connecting structure 20. The connecting structure 20 is used to secure the workpiece to the drive mechanism 10. The connecting structure 20 includes a supporting member 201 and a magnetic member 202. The magnetic attraction 202 is disposed on the support member 201. The support member 201 is connected to the driving mechanism 10. The drive mechanism 10 is used to move the support 201 from the first position 50 to the second position 60. The support 201 is used to carry a workpiece. The magnetic attraction piece 202 is used for generating magnetic attraction force to attract and fix the workpiece on the support piece 201.

In the connection structure 20 of the embodiment of the present invention, the supporting member 201 is connected to the driving mechanism 10, the magnetic member 202 is disposed on the supporting member 201, and the magnetic member 202 can generate a magnetic attraction force to fix the workpiece on the supporting member 201, so as to fix the workpiece relative to the driving mechanism 10. Therefore, compared with the mode of clamping and fixing the workpiece by the feeding clamp, the connecting structure 20 provided by the embodiment of the invention can realize the adsorption and fixation of the workpiece by the magnetic suction mode, so that the problem that the workpiece is damaged by the feeding clamp and the electrical performance of the workpiece is influenced is avoided.

In one embodiment, as shown in fig. 1 and 2, the driving mechanism 10 includes a mounting frame 104, a first driving mechanism 101, a second driving mechanism 102, and a conveying member 103. The first driving mechanism 101 and the second driving mechanism 102 are rotatably disposed on the mounting frame 104. The conveying member 103 is wound around the first driving mechanism 101 and the second driving mechanism 102. The transfer member 103 is connected with the support member 201. The first driving mechanism 101 is used for driving the supporting member 201 to move from the first position 50 to the third position through the conveying member 103. The second driving mechanism 102 is used for driving the supporting member 201 to move from the third position to the second position 60 by the conveying member 103. The third position is located on the path between the first position 50 and the second position 60. It will be appreciated that the conveyor 103 is driven by the first drive mechanism 101 to move the support member 201 carrying the workpiece from the first position 50 to the third position. Under the driving action of the second driving mechanism 102, the conveying member 103 can drive the supporting member 201 carrying the workpiece to move from the third position to the second position 60.

In one embodiment, the first drive mechanism 101 is a loading drive mechanism and the first position 50 is a loading position. Then, under the driving action of the feeding driving mechanism, the conveying member 103 can drive the supporting member 201 carrying the workpiece to move from the feeding position to the third position. The second drive 102 is an outfeed drive and the second position 60 is an outfeed position. Then, under the driving action of the discharging driving mechanism, the conveying member 103 can drive the supporting member 201 carrying the workpiece to move from the third position to the discharging position, so that the conveying member 103 can convey the supporting member 201 carrying the workpiece from the loading position to the discharging position. Of course, in other embodiments, the second drive mechanism 102 is a loading drive mechanism and the second position 60 is a loading position. The first drive mechanism 101 is a discharge drive mechanism and the first position 50 is a discharge position.

In one embodiment, as shown in fig. 1 and 2, the number of the connecting structures 20 is plural. The supporting members 201 of the plurality of connecting structures 20 are distributed on the conveying member 103 at equal intervals with a predetermined length. The first driving mechanism 101 is used for driving the conveying member 103 to move for a first preset number of preset lengths each time. The second driving mechanism 102 is used for driving the conveying member 103 to move for a second preset number of preset lengths each time. The first preset number is greater than the second preset number.

Since the supporting members 201 of the plurality of coupling structures 20 are equally spaced at a predetermined length on the transferring member 103. Under the driving action of the first driving mechanism 101, the distance of each movement of the conveying member 103 is a first preset number of preset lengths. That is, the conveying member 103 can convey a first preset number of workpieces at a time by the driving action of the first driving mechanism 101. Similarly, under the driving action of the second driving mechanism 102, the distance of each movement of the conveying member 103 is a second preset number of preset lengths. That is, the conveying member 103 can convey a second preset number of workpieces at a time under the driving action of the second driving mechanism 102. The first predetermined number is greater than the second predetermined number, and the number of workpieces transferred by the transfer member 103 moving from the first position 50 to the third position is greater than the number of workpieces transferred by moving from the third position to the second position 60. In this embodiment, the first position 50 is a material loading position, the second position 60 is a material discharging position, and the first preset number is greater than the second preset number, so that the feeding device realizes different numbers of material loading and material discharging at each time, and the number of material loading at each time is greater than the number of material discharging at each time, thereby improving the working efficiency of the feeding device.

In one embodiment, the first predetermined number is twelve and the second predetermined number is one. Then, the conveying member 103 can convey twelve workpieces at a time by the driving action of the first driving mechanism 101. The conveying member 103 can convey one workpiece at a time by the driving action of the second driving mechanism 102. Of course, the first predetermined number and the second predetermined number are not limited thereto.

In one embodiment, as shown in fig. 1 to 3, the first driving mechanism 101 includes a first driving member 1012, a first driven member 1013, and a first driving member 1011. The first driving member 1012 and the first driven member 1013 are rotatably disposed on the mounting frame 104. The transmission member 103 is wound around the first driving member 1012 and the first driven member 1013. The first driving member 1011 is connected to the first driving member 1012. The first driving member 1011 is used for driving the first driving member 1012 to rotate, so as to drive the supporting member 201 to move from the first position 50 to the third position through the conveying member 103. In this embodiment, the number of the first followers 1013 is four, and they are disposed at intervals on the mounting bracket 104. Of course, in other embodiments, the number of the first followers 1013 may be set according to actual needs, for example, three or five.

In one embodiment, as shown in fig. 1 to 3, the second driving mechanism 102 includes a second driving member 1022, a second driven member 1023 and a second driving member 1021. The second driving member 1022 and the second driven member 1023 are rotatably disposed on the mounting frame 104. The transmission member 103 is wound around the second driving member 1022 and the second driven member 1023. The second driving member 1021 is connected to the second driving member 1022. The second driving member 1021 is used for driving the second driving member 1022 to rotate, so as to drive the supporting member 201 to move from the third position to the second position 60 via the transmission member 103. In this embodiment, the number of the second followers 1023 is one. Of course, in other embodiments, the number of the second followers 1023 can be set according to actual needs, for example, three or four.

In one embodiment, as shown in fig. 1 and 2, the feeding device further includes a storage mechanism 30. The storage mechanism 30 is disposed between the first drive mechanism 101 and the second drive mechanism 102. The conveying member 103 is wound around the storage mechanism 30. The first driving mechanism 101 is further configured to drive the storage mechanism 30 to move in the first direction through the conveying member 103, so as to store the support member 201 carrying the workpiece at the third position. The second driving mechanism 102 is further configured to move the magazine mechanism 30 in a second direction opposite to the first direction via the conveying member 103 to move the support member 201 carrying the workpiece from the third position to the second position 60. The first direction is an X direction, and the second direction is an opposite direction of the X direction.

It will be appreciated that, under the driving action of the first driving mechanism 101, the conveying member 103 applies a pushing force in the first direction to the magazine 30 at the position where it contacts the magazine 30, so as to drive the magazine 30 to move in the first direction, so as to store the support member 201 carrying the workpiece at the third position. The conveying member 103 can convey a first preset number of workpieces at a time due to the driving action of the first driving mechanism 101. The conveying member 103 can convey a second preset number of workpieces at a time under the driving action of the second driving mechanism 102. The first preset number is larger than the second preset number. That is, the number of workpieces conveyed by the conveying member 103 by the first drive mechanism 101 is larger than the number of workpieces conveyed by the second drive mechanism 102. It is therefore necessary to store the extra work pieces in the third position by the stocker mechanism 30. Similarly, under the driving action of the second driving mechanism 102, the conveying element 103 applies a pushing force in the second direction to the magazine 30 at the position where the conveying element contacts the magazine 30, so as to drive the magazine 30 to move in the second direction, so as to move the support element 201 carrying the workpiece from the third position to the second position 60.

In the above embodiment, as shown in fig. 1 and 2, the magazine mechanism 30 includes the first slider 301 and the first rotating member 302. First glide 301 is slidably coupled to mount 104. The first rotating member 302 is rotatably disposed on the first sliding member 301. The transmission member 103 is wound around the first rotating member 302. The first driving mechanism 101 is further configured to drive the first rotating member 302 to rotate through the conveying member 103, and the first sliding member 301 moves along the first direction. The second driving mechanism 102 is further configured to drive the first rotating member 302 to rotate through the conveying member 103, and the first sliding member 301 moves along the second direction.

Specifically, under the driving action of the first driving mechanism 101, the conveying member 103 applies a tangential force to the first rotating member 302 at a position contacting with the first rotating member 302, so that the first rotating member 302 can rotate relative to the first sliding member 301, and the first sliding member 301 can move in the first direction, so as to store the supporting member 201 carrying the workpiece at the third position. The conveying member 103 can convey a first preset number of workpieces at a time due to the driving action of the first driving mechanism 101. The conveying member 103 can convey a second preset number of workpieces at a time under the driving action of the second driving mechanism 102. The first preset number is larger than the second preset number. That is, the number of workpieces conveyed by the conveying member 103 by the first drive mechanism 101 is larger than the number of workpieces conveyed by the second drive mechanism 102. Therefore, the extra workpieces need to be stored in the third position through the first rotating member 302 and the first sliding member 301. Similarly, under the driving action of the second driving mechanism 102, the transmitting member 103 applies a tangential force to the first rotating member 302 at a position contacting with the first rotating member 302, so that the first rotating member 302 can rotate relative to the first sliding member 301, and the first sliding member 301 can move in the second direction to move the supporting member 201 carrying the workpiece from the third position to the second position 60.

In one embodiment, as shown in fig. 1, the mounting bracket 104 is provided with a guide rail 1041. The first sliding member 301 is slidably disposed on the guide rail 1041, and is configured to provide a guiding function for the movement of the first sliding member 301 along the first direction or the second direction.

In an embodiment, as shown in fig. 1 and fig. 2, the second driving mechanism 102 is further configured to move the supporting member 201 from the second position 60 to the fourth position by the conveying member 103. The first driving mechanism 101 is further configured to move the supporting member 201 from the fourth position to the first position 50 via the conveying member 103. The fourth position is located on a path that moves from the second position 60 to the first position 50. It will be appreciated that the conveyor member 103 is operable to move the unloaded support member 201 from the second position 60 to the fourth position upon actuation of the second drive mechanism 102. Under the driving action of the first driving mechanism 101, the conveying member 103 can drive the unloaded supporting member 201 to move from the fourth position to the first position 50. In this embodiment, the second driving mechanism 102 is a discharge driving mechanism, and the second position 60 is a discharge position. Then, under the driving action of the discharging driving mechanism, the conveying element 103 can drive the unloaded supporting element 201 to move from the discharging position to the fourth position. The first drive mechanism 101 is a loading drive mechanism and the first position 50 is a loading position. Then, under the driving action of the feeding driving mechanism, the conveying member 103 can drive the empty supporting member 201 to move from the fourth position to the feeding position, so that the conveying member 103 can convey the empty supporting member 201 from the discharging position to the feeding position.

In one embodiment, as shown in fig. 1 and 2, the feeding device further includes a buffering mechanism 40. The buffer mechanism 40 is disposed between the first driving mechanism 101 and the second driving mechanism 102, and the transmission member 103 is wound around the buffer mechanism 40. The second driving mechanism 102 is further configured to move the buffering mechanism 40 along the second direction via the conveying member 103 to buffer the empty supporting member 201 at the fourth position. The first driving mechanism 101 is further configured to move the buffering mechanism 40 along the first direction by the conveying member 103 to move the unloaded supporting member 201 from the fourth position to the first position 50.

It will be appreciated that under the driving action of the second driving mechanism 102, the conveying member 103 will give a pushing force in the second direction to the buffering mechanism 40 at the position where the conveying member contacts with the buffering mechanism 40, so as to drive the buffering mechanism 40 to move in the second direction, so as to buffer the empty supporting member 201 at the fourth position. The distance of each movement of the conveying element 103 is a first preset number of preset lengths under the driving action of the first driving mechanism 101. Under the driving action of the second driving mechanism 102, the distance of each movement of the conveying member 103 is a second preset number of preset lengths. The first preset number is larger than the second preset number. That is, the number of the empty supporting members 201 conveyed by the first driving mechanism 101 by the conveying member 103 is larger than the number of the empty supporting members 201 conveyed by the second driving mechanism 102. Therefore, the buffering mechanism 40 needs to be provided to buffer the extra empty supporting member 201 in the fourth position. Similarly, under the driving action of the first driving mechanism 101, the conveying member 103 applies a pushing force to the buffering mechanism 40 along the first direction at the position where the conveying member contacts the buffering mechanism 40, so as to drive the buffering mechanism 40 to move along the first direction, so as to move the unloaded supporting member 201 from the fourth position to the first position 50.

In the above embodiment, as shown in fig. 1 and 2, the damping mechanism 40 includes the second sliding member 401 and the second rotating member 402. Second glide 401 is slidably coupled to mount 104. The second rotating member 402 is rotatably disposed on the second sliding member 401. The transmission member 103 is wound around the second rotation member 402. The first driving mechanism 101 is further configured to drive the second rotating member 402 to rotate via the conveying member 103, and the second sliding member 401 moves along the first direction. The second driving mechanism 102 is further configured to drive the second rotating member 402 to rotate via the conveying member 103, and the second sliding member 401 moves along the second direction.

Specifically, under the driving action of the second driving mechanism 102, the transmitting member 103 applies a tangential force to the second rotating member 402 at a position contacting the second rotating member 402, so that the second rotating member 402 can rotate relative to the second sliding member 401, and the second sliding member 401 can move in the second direction to buffer the unloaded supporting member 201 at the fourth position. The distance of each movement of the conveying element 103 is a first preset number of preset lengths under the driving action of the first driving mechanism 101. Under the driving action of the second driving mechanism 102, the distance of each movement of the conveying member 103 is a second preset number of preset lengths. The first preset number is larger than the second preset number. That is, the number of the empty supporting members 201 conveyed by the first driving mechanism 101 by the conveying member 103 is larger than the number of the empty supporting members 201 conveyed by the second driving mechanism 102.
