Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tape clamp structures, in particular to an adhesive pulling clamp structure for preventing adhesive tape from sticking. Background Art

[0002] Adhesive tape is widely used in the production process of lithium-ion batteries. When the machine is automatically pasting, the tape often sticks to the clamping jaws. For example, the gluing station clamping and glue pulling clamping jaws of the assembly line ultrasonic final welding machine, adapter welding machine, and Mylar packaging machine all have the phenomenon of sticking blue glue. As a result, when the glue head takes the blue glue, the blue glue sticks to the glue pulling clamping jaws, the glue removal fails, and the vacuum suction alarm of the glue head is triggered. The alarm needs to be eliminated and the glue needs to be re-prepared. Although the alarm can be reduced by sticking granular glue on the glue station clamping and glue pulling clamping jaws, the granular glue needs to be replaced regularly. The price of granular glue is relatively expensive, which increases the production cost. Replacing granular glue also requires manpower and time, which increases the labor intensity. Utility Model Content

[0003] The utility model aims to provide a glue pulling clamp structure which avoids sticky tape, which can improve the release effect of the glue pulling clamp after clamping the tape, reduce the occurrence of sticky tape, avoid the use of granular glue, reduce costs and improve production efficiency.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A glue-pulling clamp structure for avoiding sticky tape comprises a first clamp and a second clamp, which are clamped at two sides of the tape respectively, and the first clamp is clamped at the side of the tape with glue; the first clamp comprises an abutment block, which is a magnetic conductor, and the abutment block is slidably connected or rotationally connected to the first clamp, and the movement direction is along the direction of approaching or leaving the second clamp, and a magnetic attraction block for attracting the abutment block is provided at the corresponding position of the second clamp.

[0006] By adopting the above technical solution, the first clamp and the second clamp are clamped on both sides of the tape. When separated, the magnetic block attracts the abutment block, causing the abutment block to stay briefly, while the other parts of the first clamp leave, first partially separating the tape and finally separating the tape on the abutment block, thereby reducing the occurrence of sticky tape.

[0007] Furthermore, an elastic member is further provided in the first clamping jaw, and the elastic member drives the abutting block to move in a direction away from the second clamping jaw.

[0008] By adopting the above technical solution, firstly, the abutment block moves in a direction away from the second clamping jaw under the drive of the elastic member, and when the clamping jaws are merged, the abutment block will not hit the magnet heavily, thereby reducing the collision between the abutment block part and the tape, and facilitating the subsequent separation;

[0009] Secondly, the magnetic block attracts the abutment block, causing the abutment block to stay briefly, thereby achieving partial separation of the tape. Then, as the distance between the first clamp and the second clamp increases, the elastic member overcomes the effect of the magnetic block, causing the abutment block to also leave, and further rotates the abutment block to the inside of the clamping side of the first clamp, so that the tape on the abutment block is separated, further reducing the occurrence of sticky tape.

[0010] Furthermore, the abutment block is rotatably connected to the first clamping jaw, and the elastic member includes a torsion spring, which drives the abutment block to move in a direction away from the second clamping jaw.

[0011] By adopting the above technical solution, the abutment block is driven by the torsion spring to overcome the effect of the magnetic attraction block and leave the second clamping jaw.

[0012] Furthermore, the first clamping jaw is connected to a limit block, and the limit abutment block is close to the second clamping jaw and / or is at the farthest position away from the second clamping jaw.

[0013] By adopting the above technical solution, the limiting abutment block is close to the second clamping jaw and / or is at the farthest position away from the second clamping jaw.

[0014] Furthermore, the inner end of the abutment block is also connected to a push block. When the first clamp and the second clamp are close to each other, the second clamp pushes the push block, driving the abutment block to overcome the force of the elastic member and rotate until the magnetic block and the abutment block are attracted to each other.

[0015] By adopting the above technical solution, when the first clamping jaw and the second clamping jaw approach each other, the abutting block is driven to overcome the force of the elastic member and rotate until the magnetic block and the abutting block attract each other.

[0016] Furthermore, the push block is a roller or a roller, which is rotatably connected to the abutment block.

[0017] By adopting the above technical solution, it is convenient for the second clamping claw to push the abutment block to rotate.

[0018] Furthermore, the portions of the first clamping jaw and the abutting block that are in contact with the adhesive tape are provided with granular protrusions to reduce the contact surface with the adhesive tape.

[0019] By adopting the above technical solution, the contact area between the adhesive tape and the adhesive tape is reduced, further facilitating separation from the adhesive tape.

[0020] Furthermore, the portions of the first clamping jaw and the abutting block in contact with the tape are provided with an anti-stick coating.

[0021] By adopting the above technical solution, separation from the tape is further facilitated.

[0022] In summary, the utility model has the following beneficial effects:

[0023] When the first clamping jaw and the second clamping jaw are close to each other, the second clamping jaw pushes the pushing block, driving the abutting block to overcome the force of the elastic member and rotate until the magnetic block and the abutting block attract each other; the first clamping jaw and the second clamping jaw are clamped on both sides of the tape, and when separated, the magnetic block attracts the abutting block, causing the abutting block to stay briefly, while the other part of the first clamping jaw leaves, first realizing partial separation of the tape, and then, as the distance between the first clamping jaw and the second clamping jaw increases, the abutting block is driven by the torsion spring to overcome the effect of the magnetic block and leave the second clamping jaw, so that the abutting block also leaves, and further rotates the abutting block to the inside of the clamping side of the first clamping jaw, so that the tape on the abutting block is separated, further reducing the occurrence of sticky tape;

[0024] The utility model can improve the release effect of the adhesive tape after the adhesive pulling clamping claw clamps the adhesive tape, reduce the occurrence of the adhesive tape sticking, avoid the use of granular adhesive, reduce the cost, and improve the production efficiency.

[0029] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, and this embodiment does not constitute a limitation of the utility model. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] A glue pulling clamp structure to avoid sticking tape, such as Figure 1 As shown, it includes a first clamping jaw 1 and a second clamping jaw 2, which are clamped on both sides of the tape respectively, and the first clamping jaw 1 is clamped on the side of the tape with glue;

[0031] The first clamping jaw 1 includes an abutment block 3, which is a magnetic conductor. The abutment block 3 is slidably connected or rotatably connected to the first clamping jaw 1, and the movement direction is in the direction of approaching or leaving the second clamping jaw 2. A magnetic attraction block 21 for attracting the abutment block 3 is provided at a corresponding position of the second clamping jaw 2.

[0032] The first clamp 1 and the second clamp 2 are clamped on both sides of the tape. When separated, the magnetic block 21 attracts the abutment block 3, so that the abutment block 3 stays briefly to press the tape, while the other parts of the first clamp 1 leave to achieve partial separation from the tape. Finally, the abutment block 3 leaves to separate the tape thereon, reducing the occurrence of sticky tape.

[0033] like Figure 1 As shown, an elastic member is also provided in the first clamping jaw 1, and the elastic member drives the abutting block 3 to move in a direction away from the second clamping jaw 2; the magnetic block 21 attracts the abutting block 3, so that the abutting block 3 stays for a short time, pressing the tape, and the tape is separated from the main body of the first clamping jaw 1, and then, as the distance between the first clamping jaw 1 and the second clamping jaw 2 increases, the elastic member overcomes the effect of the magnetic block 21, so that the abutting block 3 leaves the second clamping jaw 2, and rotates the abutting block 3 to the inside of the clamping side of the first clamping jaw 1, so that the tape on the abutting block 3 is also separated, further reducing the occurrence of sticky tape;

[0034] In this embodiment, the abutment block 3 is rotatably connected to the first clamping jaw 1, and the elastic member includes a torsion spring, which drives the outer end of the abutment block 3 to move away from the second clamping jaw 2. The torsion spring can also be replaced by an elastic member such as a compression spring, which directly pushes the outer end of the abutment block 3 to move away from the second clamping jaw 2 at the inner end, so as to facilitate installation; in some embodiments, the first clamping jaw 1 is located on the lower side, and its abutment block 3 can also be self-repositioned; the abutment block 3 can also be slidably connected to the first clamping jaw 1, and its separation from the magnet block 21 is achieved by means of a compression spring or an electric drive structure, so as to facilitate separation from the tape.

[0035] like Figure 1 and Figure 2 As shown, the first clamping jaw 1 is connected to a limit block 11, which is located on the outside of the abutment block 3, limiting the abutment block 3 from rotating to the farthest position away from the second clamping jaw 2. A groove for the abutment block 3 to move is provided in the main body of the first clamping jaw 1, and the bottom of the groove is located in the inner end direction of the abutment block 3, which can also limit the abutment block 3 from rotating to the farthest position close to the second clamping jaw 2 and away from the second clamping jaw 2;

[0036] The inner end of the abutment block 3 is also connected to a push block 31. When the first clamping jaw 1 and the second clamping jaw 2 approach each other, the second clamping jaw 2 pushes the push block 31, driving the abutment block 3 to overcome the force of the elastic member and rotate until the magnetic block 21 and the abutment block 3 are attracted to each other. In this embodiment, the push block 31 is a roller or a roller, which is rotatably connected to the abutment block 3; when the first clamping jaw 1 and the second clamping jaw 2 approach each other, it drives the abutment block 3 to overcome the force of the elastic member and rotate until the magnetic block 21 and the abutment block 3 are attracted to each other.

[0037] like Figure 1 and Figure 2 As shown, in order to further facilitate the separation of the first clamping jaw 1 from the adhesive tape, the first clamping jaw 1 and the contacting portion of the abutment block 3 with the adhesive tape are integrally connected with a plurality of granular protrusions 12 to reduce the contact surface with the adhesive tape;

[0038] In some other embodiments, the first clamping jaw 1 and the inner side of the abutment block 3 (the part contacting the tape) are coated with an anti-stick coating, and nano-coating and other technologies can be used to achieve anti-stick and wear-resistant properties. Other anti-stick materials can also be used.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions should also be deemed to fall within the protection scope of the technical solution of the present invention.
