[0002] The tape pulling device is usually applied to the glue sticking process. When sticking the tape, it is necessary to use the tape pulling device to pull out the tape on the film roll. Structurally, the tape pulling device includes a clamping mechanism and a traction mechanism. The clamping mechanism is used to clamp one end of the tape, and the traction mechanism drives the clamping mechanism to move, so that the tape on the film roll can be pulled out.

[0003] The existing clamping mechanism includes two clamping blocks and a driving member for driving the two clamping blocks to approach or separate from each other to clamp or loosen the tape. Among them, the tape is composed of a release paper and an adhesive layer. The clamping surface of one clamping block contacts the adhesive surface of the tape, and the clamping surface of the other clamping block contacts the back adhesive surface of the tape.

[0004] However, the clamping surfaces of the two clamping blocks in the existing clamping mechanism are generally flat. When the two clamping blocks clamp the tape, the stress area of the tape is large, and the adhesive layer in the tape will be extruded along the edge of the tape, resulting in the glue adhering to the clamping blocks. Moreover, it is not easy to separate after the clamping surface of one clamping block contacts the adhesive surface of the tape, which affects the normal operation of the equipment. Content of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an anti-sticking jaw, which can reduce the extrusion of the adhesive layer of the tape and avoid the glue of the tape from adhering to the jaw.

Detailed Description of the Preferred Embodiments

[0024] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present utility model can be combined with each other without conflicting with each other.

[0025] Refer to Figures 1 to 4, A non-stick gripper provided by an embodiment of the present utility model includes a first clamping arm 100, a second clamping arm 110, and a driving member 120. The driving member 120 is used to drive the first clamping arm 100 and the second clamping arm 110 to approach or separate from each other to clamp or release a tape 130. A first clamping portion 140 is provided on a side of the first clamping arm 100 close to the second clamping arm 110, and a second clamping portion 150 is provided on a side of the second clamping arm 110 close to the first clamping arm 100. The first clamping portion 140 is a planar structure, and the second clamping portion 150 is a plurality of convex portions 160. The plurality of convex portions 160 are arranged in a row in the width direction of the tape 130.

[0026] When clamping the tape 130, the first clamping portion 140 contacts the back glue surface of the tape 130, and the second clamping portion 150 contacts the glue-coated surface of the tape 130. Specifically, the convex points of the plurality of convex portions 160 arranged in a row all contact the glue-coated surface of the tape 130, which can not only make the tape 130 receive a clamping force in the width direction but also reduce the force-bearing area of the tape 130. Thus, it can reduce the extrusion of the glue-coated layer of the tape 130 and avoid the glue of the tape 130 from adhering to the gripper.

[0027] Furthermore, the plurality of convex portions 160 are all arc-shaped structures. When the convex points of the convex portions 160 contact the glue-coated surface of the tape 130, the convex points of the convex portions 160 are not easy to pierce the glue-coated layer of the tape 130. Thus, the integrity of the tape 130 is ensured.

[0028] Even further, a non-stick glue coating is provided on the surface of the second clamping portion 150. When the tape 130 is released, the tape 130 is easily separated from the second clamping portion 150, preventing the tape 130 from sticking to the second clamping portion 150.

[0029] In some preferred embodiments, a leveling clamping block 170 is further provided on the first clamping arm 100. The first clamping portion 140 is provided on the leveling clamping block 170. The leveling clamping block 170 is used to adjust the parallelism between the first clamping portion 140 and the second clamping portion 150. Thus, it can make the tape 130 receive uniform force and ensure the stability during tape pulling.

[0030] Specifically, the leveling clamping block 170 is a long-shaped structure. The length direction of the leveling clamping block 170 extends along the width direction of the tape 130. The middle of the leveling clamping block 170 is rotatably connected to the first clamping arm 100, and a locking member is provided between the leveling clamping block 170 and the first clamping arm 100.

[0031] It can be understood that by rotating the leveling clamping block 170, the first clamping portion 140 on the leveling clamping block 170 and the second clamping portion 150 are made parallel to each other, and then the leveling clamping block 170 is locked on the first clamping arm 100 through the locking member. Thus, the leveling of the first clamping portion 140 can be achieved.

[0032] Further, the middle part of the leveling clamping block 170 is connected to the first clamping arm 100 through a first bolt 180. An adjusting hole 190 is provided in the middle part of the leveling clamping block 170, and a first threaded hole 200 is provided on one side of the first clamping arm 100. The stepped hole corresponds to the first threaded hole 200. The screw rod of the first bolt 180 passes through the adjusting hole 190 and is screwed with the first threaded hole 200. The nut of the first bolt 180 is pressed against the leveling clamping block 170. When it is necessary to adjust the balance of the leveling clamping block 170, loosen the first bolt 180 and the locking member, then swing the leveling clamping block 170 so that the first clamping portion 140 and the second clamping portion 150 on the leveling clamping block 170 are parallel to each other. Finally, tighten the first bolt 180. At the same time, lock the leveling clamping block 170 on the first clamping arm 100 through the locking member. Thus, it is convenient to adjust the leveling clamping block 170. At the same time, the first bolt 180 can further lock the leveling clamping block 170 to ensure the stability of the clamping jaw during the process of clamping the tape 130.

[0033] Specifically, the adjusting hole 190 is a stepped hole. The smaller hole of the stepped hole accommodates the screw rod of the first bolt 180 to pass through, and the larger hole of the stepped hole accommodates the nut of the first bolt 180. Thus, the nut of the first bolt 180 can be buried in the leveling clamping block 170 to prevent the first bolt 180 from interfering with other components of the equipment.

[0034] In some preferred embodiments, the locking member is a second bolt 210. An adjusting groove 220 is provided on the leveling clamping block 170, and a second threaded hole 230 is provided on one side of the first clamping arm 100. The adjusting groove 220 corresponds to the second threaded hole 230. The second bolt 210 passes through the adjusting groove 220 and is screwed with the second threaded hole 230. The nut of the second bolt 210 is pressed against the leveling clamping block 170.

[0035] It should be noted that when the leveling clamping block 170 rotates around the axis of the first bolt 180, the leveling clamping block 170 drives the adjusting groove 220 to swing by a certain angle, and the adjusting groove 220 can accommodate the second bolt 210 to pass through at any position within the adjustment range. Thus, it is convenient to lock or loosen the locking member, and its structure is simple and easy to manufacture.

[0036] Further, the adjusting groove 220 is a long groove. The length direction of the long groove is perpendicular to the length direction of the leveling clamping block 170. The groove width of the adjusting groove 220 is greater than the screw rod diameter of the second bolt 210. Thus, it is convenient to machine the adjusting groove 220 and reduce the machining difficulty of the adjusting groove 220.

[0037] In other embodiments, the adjusting groove 220 can also be set as an arc groove, and the arc of the arc groove is centered on the rotation center of the leveling clamping block 170.

[0038] In some preferred embodiments, the number of the locking members is two, and the two locking members are symmetrically arranged along the rotation center of the leveling clamping block 170. Thus, the firmness of the connection between the leveling clamping block 170 and the first clamping arm 100 can be improved, and moreover, the locking forces of the two locking members acting on the leveling clamping block 170 can be balanced.

[0039] In some preferred embodiments, the driving member 120 is a finger cylinder, and the first clamping arm 100 and the second clamping arm 110 are respectively arranged at two output ends of the finger cylinder. The finger cylinder can drive the first clamping arm 100 and the second clamping arm 110 to approach or separate from each other simultaneously, thereby reducing the assembly difficulty of the clamping jaws.

[0040] The above is a specific description of the preferred embodiments of the present invention, but the present invention is not limited to the described embodiments. Those skilled in the art can also make various equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
