Therefore, other possible implementations that can be known to those skilled in the art based on the embodiments described herein belong to the scope of protection of the present application.

Embodiment of film sticking clamp

Fig. 1 and 2 show the structure of an embodiment of the film attaching jig. It should be noted that, for the sake of understanding of the structure and the operation principle of the pasting jig, the sheet 101 to be pasted is shown in fig. 1 and 2, but the sheet 101 to be pasted does not constitute an integral part of the pasting jig.

As shown in fig. 1 and 2, the film attaching jig of the embodiment includes a base plate 10, a floating plate 20, a compression spring 30 as an example of an elastic member, and an angle restricting mechanism 40. Wherein the floating plate 20 is disposed above the base plate 10 and can rotate between a horizontal position and an inclined position as shown in fig. 2; a compression spring 30 is provided between the base plate 10 and the floating plate 20 for rotating the floating plate 20 up to an inclined position; the angle limiting mechanism 40 is used to limit the angle of inclination of the floating plate 20 in the inclined position with respect to the horizontal plane.

In an alternative embodiment, the base plate 10 and the floating plate 20 may be formed in a substantially rectangular shape having a dimension in the transverse direction X smaller than that in the longitudinal direction Y. Alternatively, the bottom plate 10 and the floating plate 20 may be formed in other shapes such as a substantially square shape; that is, the present invention does not limit the outer shapes of the bottom plate 10 and the floating plate 20.

In an alternative embodiment, the bottom plate 10 has support side plates 13 as an example of a rotation support member on opposite sides in the longitudinal direction Y, and the support side plates 13 are provided with rotation shafts 14 extending in the longitudinal direction Y; the floating plate 20 has pivot holes 23 at opposite sides in the longitudinal direction Y, and the shaft 14 is inserted into the pivot holes 23. Thus, the floating plate 20 can be pivotally connected to the base plate 10 by the engagement between the pivot hole 23 and the pivot shaft 14. Alternatively, the pivotal shaft is provided on the floating plate 20 and the pivot hole is correspondingly provided on the support side plate 13, which also enables the pivotal connection between the floating plate 20 and the base plate 10.

The base plate 10 has an upper surface disposed horizontally. As shown in fig. 2, the bottom surface of the floating plate 20 may include a curved surface 272 and a flat surface 271, the curved surface 272 being disposed on the same lateral side of the floating plate 20 as the pivot hole 23. The cambered surface 272 is arranged to avoid interference with the bottom plate 10 during the process of rotating the floating plate 20 upwards to the inclined position, and the plane 271 is arranged to ensure that a horizontal plane contact is formed between the floating plate 20 and the bottom plate 10 when the floating plate 20 is in the horizontal position.

The floating plate 20 is provided with a bearing plane 21 and a limiting part, and the sheet material 101 to be filmed is placed on the bearing plane 21 and limited by the limiting part. In an alternative embodiment, the stopper portion includes a first stopper rib 221 and a second stopper rib 222 perpendicular to each other, wherein the first stopper rib 221 is provided at a low side (i.e., a side having a relatively low height in an initial state, i.e., a side where the hole 23 is pivoted in the lateral direction) of the floating plate 20. Optionally, a limiting part such as a limiting protrusion can be used for limiting the film sheet 101 to be pasted; that is, the specific structure of the limiting portion in the present invention is not limited as long as the placement position of the sheet 101 to be filmed on the bearing plane 21 can be limited.

Further, the floating plate 20 may have an adsorption structure for adsorbing the sheet 101 to be filmed on the carrying plane 21. In one possible embodiment, as shown in fig. 1, the floating plate 20 has one or more (e.g., two as shown in fig. 1) recesses 25 recessed into the bearing plane 21, and the bottom surfaces of the recesses 25 are provided with negative pressure holes (not visible in the drawings) that communicate with a negative pressure generating system. In this way, when the magnetic sheet material is to be applied, the magnet is placed in the recess 25, and the magnetic sheet material is attracted to the flat surface 21 by the magnetic force of the magnet. When the non-magnetic sheet material is filmed, the magnet can be removed from the recess 25, and the non-magnetic sheet material is adsorbed on the bearing plane 21 through the negative pressure hole communicated with the negative pressure generating system.

In another possible embodiment, the floating plate 20 is provided with a magnet-mounting recess and a negative pressure hole at the same time; that is, the negative pressure hole and the magnet-mounting recess are provided at different positions of the floating plate 20. Thus, the magnet removing and installing operation is not needed, and the film sticking clamp is suitable for sticking films of magnetic and non-magnetic sheet materials and is more convenient to use. Further, the floating plate 20 may be formed with a material placing and taking recess 26 to facilitate placing the material on the carrying plane 21 before the film is attached and removing the material from the carrying plane 21 after the film is attached.

A compression spring 40 is provided between the base plate 10 and the floating plate 20 for rotating the floating plate 20 upward to an initial inclined position. In an alternative embodiment, spring receiving grooves for receiving the compression springs 40 are provided on both the floating plate 20 and the base plate 10. Specifically, the bottom plate 10 is provided with a first spring receiving groove 12, the floating plate 20 is provided with a second spring receiving groove 28, and the compression spring 40 is disposed in the first spring receiving groove 12 and the second spring receiving groove 28.

In the present invention, the number of the compression springs 40 may be one or more. In a preferred embodiment, a plurality of (e.g., 3) compression springs 30 are spaced apart in the longitudinal direction Y to provide smoother rotation of the floating plate 20. It should be noted that fig. 1 shows the base plate 10 having 3 linearly arranged first spring-receiving grooves 12, but only the compression spring 30 is shown within the intermediate first spring-receiving groove 12.

In the initial state, the floating plate 20 is in an inclined position as shown in fig. 2, in which the angle of inclination a of the floating plate 20 with respect to the horizontal plane may be 0.1-5 °, more particularly 0.5-3 °. In the present invention, the inclination angle of the floating plate 20 with respect to the horizontal plane is based on the bearing plane 21. That is, as shown in fig. 2, the inclination angle of the bearing plane 21 with respect to the horizontal plane is set as the inclination angle of the floating plate 20. When the floating plate 20 is in a horizontal position, the bearing plane 21 is also in a horizontal state.

The angle of inclination of the floating plate 20 at the inclined position is controlled by an angle limiting mechanism 40. In an alternative embodiment, the angle limiting mechanism 40 includes an L-shaped support member 41 and a limiting member 42, the support member 41 is installed at a side portion of the base plate 10, and the limiting member 42 is height-adjustably installed on the support member 41 and abuts the abutment protrusion 24 of the floating plate 20, thereby enabling to flexibly control the initial inclination angle of the floating plate 20 as desired. Both the angle stopper mechanism 40 and the abutment protrusion 24 are located on the high side of the floating plate 20 (i.e., on the side having a relatively high height in the initial state).

In an alternative embodiment, a threaded connection is formed between stop member 42 and support member 41 such that the height of stop member 42 is adjustable. Specifically, a screw or a bolt may be used as the stopper member 42, and the screw or the bolt may be moved up and down when rotated, thereby adjusting the initial inclination angle of the floating plate 20.

Film application apparatus embodiment

Fig. 3 is a schematic structural diagram of an embodiment of a film sticking device. As shown in fig. 3, the film sticking device comprises a mounting table 201, a suction cup 202 and the film sticking fixture of the above embodiment. Note that, although the sheet stock 101 to be film-pasted and the adhesive film 102 as an example of the cover film are shown in fig. 3, the sheet stock 101 to be film-pasted and the adhesive film 102 do not constitute a part of the film-pasting device.

Wherein, the pad pasting anchor clamps are fixed on the installation mesa 201, and the sucking disc 202 sets up directly over the pad pasting anchor clamps. The suction cup 202 is connected to a lift driving device (not shown) and is driven by the lift driving device to move up and down.

Specifically, the base plate 10 of the film sticking fixture is fixedly mounted to a mounting table 201 (see fig. 3) of the film sticking apparatus. In an alternative embodiment, the base plate 10 is secured to the mounting deck 201 by way of a bolt or screw fastening. For example, a plurality of mounting holes 11 (e.g., four as shown in fig. 1) may be provided on the base plate 10, and screws or bolts may be inserted through the mounting holes 11 and then connected to the mounting table 201, thereby fixing the base plate 10 to the mounting table 201.

The suction cup 202 is used for sucking (e.g., sucking under negative pressure) the adhesive film 102. In the film laminating operation, the suction cup 202 is driven by the elevating drive device to move downward. After the suction cup 202 moves downwards as shown in fig. 4, in the initial stage of film sticking, one side of the adhesive film 102 is aligned with and closely attached to one side of the sheet 101 to be stuck, and as the suction cup 202 continues to press the floating plate 20 downwards, the floating plate 20 will gradually rotate from the inclined position in the initial stage as shown in fig. 4 to the horizontal position as shown in fig. 5, during which the adhesive film 102 is gradually stuck to the surface of the sheet 101 to be stuck, and the film sticking operation is completed.

After the film attaching operation is completed, the floating plate 20 is rotated upward to the initial inclined position by the compression spring 30 as the suction cup 202 is moved upward. Then, the sheet-like material on which the film sticking has been completed can be removed from the floating plate 20, and the film sticking operation can be performed again.

Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the scope of the utility model. Any person skilled in the art can make some modifications without departing from the scope of the utility model, and all changes or modifications made according to the present invention should be covered by the protection scope of the present invention.
