[0026] The following describes the embodiments of the present invention with reference to the accompanying drawings. In the process, to ensure clarity and convenience of the description, we may exaggerate the width of the lines or the size of the components in the drawings.

[0027] In addition, the following terms are defined based on the functions of the present invention and may vary depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire content of this specification.

[0028] like Figures 1 to 7As shown, a processing equipment for transparent conductive polyimide film includes a processing frame 1, on which a winding roller 2, a tensioning device 3 and a winding device 4 are arranged from left to right. By adopting the above technical solution, the rolled polyimide film is placed on the winding roller 2 during operation, and the polyimide film passes through the tensioning device 3 and is connected to the winding device 4. The winding device 4 is installed with specified specifications to wind the polyimide film during operation. The tensioning device 3 can keep the polyimide film in a taut state at all times during the winding process. The winding device 4 can be adjusted in position during operation, which makes it convenient for operators to replace the polyimide film roll and improves the processing efficiency of the polyimide film.

[0029] The tensioning device 3 includes guide rollers 31 uniformly arranged on the processing frame 1 through bearings, annular rings 32 are symmetrically provided at both ends of the guide rollers 31 by sliding fit, and the annular rings 32 on the same side of the multiple guide rollers 31 are connected by an auxiliary frame 33. An adjustment mechanism 34 is provided on the processing frame 1, and the auxiliary frame 33 is connected to the adjustment mechanism 34. A fixed frame 35 is installed on the processing frame 1, and an adjustment cylinder 36 is installed at the lower end of the fixed frame 35. An adjustment frame 37 is installed on the adjustment cylinder 36. Guide rollers 38 are provided between the inner walls of the adjustment frame 37, and a telescopic rod 39 is provided between the adjustment frame 37 and the fixed frame 35.

[0030] By adopting the above technical solution, the polyimide film on the winding roller 2 is sequentially passed through the guide roller 31 and the guide roller 38 and wound on the winding device 4 during operation. During operation, the polyimide film passes through the tensioning device 3 in an S-shaped structure. According to the tightness of the polyimide film during operation, the adjusting cylinder 36 works synchronously. During operation, the adjusting cylinder 36 drives the guide roller 38 to adjust the height through cooperation with the telescopic rod 39. The guide roller 38 controls the polyimide film to be always in a taut state during operation. In addition, the adjusting mechanism 34 can be adaptively adjusted according to the width of the polyimide film during operation to ensure the tightness of the polyimide film during the winding process and the precision of the specifications of the polyimide film after winding.

[0031] The adjusting mechanism 34 includes a bidirectional screw 341 arranged on the processing frame 1 through a bearing, and a first motor 342 is installed on the processing frame 1 through a motor seat. The output shaft of the first motor 342 is connected to one end of the bidirectional screw 341 through a coupling, and a moving block 343 is provided on the bidirectional screw 341 through a threaded transmission. The lower end of the moving block 343 is slidably set on the processing frame 1, and the upper end of the moving block 343 is connected to the auxiliary frame 33.

[0032] When using the above technical solution, the first motor 342 is started to control the bidirectional screw 341 to rotate according to the width of the polyimide film to be processed. During the rotation, the bidirectional screw 341 synchronously drives the auxiliary frames 33 on the two moving blocks 343 to move towards each other. During this process, the auxiliary frame 33 synchronously controls the annular ring 32 to adjust toward the middle of the guide roller 31, ensuring that there will be no winding deviation problem during the winding process of the polyimide film.

[0033] The winding device 4 includes a winding frame 41 slidably arranged on the processing frame 1, an electric slider 42 is installed on the winding frame 41, and the electric slider 42 is installed on the processing frame 1. The winding frame 41 is installed with a second motor 43 through a motor seat, and the output shaft of the second motor 43 passes through the winding frame 41 through a bearing, and a winding mechanism 44 is installed on the output shaft of the second motor 43. A supporting mechanism 45 is provided on the winding frame 41, and a docking mechanism 46 is provided on the processing frame 1.

[0034] By adopting the above technical solution, in the initial state, the electric slider 42 controls the winding frame 41 to move to the non-working position, and the polyimide film winding roll to be placed on the winding mechanism 44. The support mechanism 45 plays an auxiliary supporting role for the winding mechanism 44 in this process, and then the electric slider 42 controls the winding frame 41 to move to the working position, and the docking mechanism 46 works in coordination with the winding mechanism 44 to ensure that the winding mechanism 44 can stably and smoothly wind the polyimide film during operation.

[0035] The support mechanism 45 includes a mounting groove provided on the winding frame 41 , a support cylinder 451 is installed in the mounting groove, a bracket 452 is installed on the support cylinder 451 , and the bracket 452 is in an arc structure.

[0036] The winding mechanism 44 includes a winding tube 441 connected to the second motor 43, and the winding tube 441 is symmetrically provided with a pushing groove. A two-way cylinder 442 is installed in the winding tube 441, and a pushing frame 443 is symmetrically installed on the two-way cylinder 442. An auxiliary spring rod 444 is symmetrically installed on the pushing frame 443, and a fixing plate 445 is installed on the auxiliary spring rod 444. A telescopic part 446 is provided on the fixing plate 445 close to the docking plate 462, and a push rod 447 is installed on the fixing plate 445 close to the second motor 43. The winding tube 441 is symmetrically provided with internal support parts that cooperate with the pushing frame 443.

[0037] By adopting the above technical solution, during operation, after the winding drum is sleeved on the winding tube 441, the two-way cylinder 442 is started. During operation, the two-way cylinder 442 first drives the push rod 447 and the telescopic member 446 to start working synchronously through the auxiliary spring rod 444 and the fixed plate 445. During operation, the push rod 447 and the telescopic member 446 cooperate with each other to push the winding drum to the middle position of the winding tube 441, ensuring that the position of the winding drum corresponds to the polyimide film, ensuring that the polyimide film can be neatly wound on the winding drum;

[0038] When the position of the winding drum is adjusted, the telescopic part 446 and the push rod 447 are tightly fitted at both ends of the winding drum. At this time, the two-way cylinder 442 continues to move. With the cooperation of the auxiliary spring rod 444, the telescopic part 446 and the push rod 447 remain stationary, and the pushing frame 443 continues to move following the two-way cylinder 442. The pushing frame 443 has an inclined structure on the side facing the inner support. During the movement, the pushing frame 443 squeezes the inner support. After being squeezed, the inner support moves toward the inner wall of the winding drum, thereby locking the winding drum to ensure that the winding drum can effectively wind the polyimide film when it rotates following the winding tube 441.

[0039] The inner support member includes a protruding groove uniformly opened along the circumference of the winding tube 441 , an inner support block 448 is slidably arranged in the protruding groove, and an inner support spring is arranged between the inner support block 448 and the inner wall of the winding tube 441 .

[0040] By adopting the above technical solution, the pushing frame 443 squeezes the inner support block 448 during operation, and the squeezed inner support block 448 moves toward the inner wall of the winding cylinder to internally support and lock the winding cylinder.

[0041] The docking mechanism 46 includes a docking cylinder 461 installed on the processing frame 1, a docking plate 462 is installed on the docking cylinder 461, the docking plate 462 is slidably set on the processing frame 1, a docking groove is provided on the docking plate 462, a docking block 463 is provided in the docking groove through a bearing, and a card slot is provided on the docking block 463.

[0042] A clamping block 449 that cooperates with a clamping slot is installed on the output shaft of the winding tube 441 away from the second motor 43.

[0043] By adopting the above technical solution, when the winding frame 41 moves to the working position, the docking cylinder 461 is started. During operation, the docking cylinder 461 drives the docking plate 462 to move toward the direction of the winding tube 441, so that the clamping block 449 is inserted into the clamping slot to ensure the stability of the winding tube 441 during rotation.

[0044] The telescopic member 446 includes an adjustment hole provided on the fixed plate 445 , a push rod 440 is slidably arranged in the adjustment hole, a return spring is sleeved between the push rod 440 and the fixed plate 445 , and an inclined groove cooperating with the push rod 440 is provided on the winding tube 441 .

[0045] By adopting the above technical solution, when it is necessary to dismantle or place the winding drum during work, the two-way cylinder 442 is used to control the fixing plate 445 to move toward the docking block 463, so that the fixing plate 445 moves to the top of the inclined slot. During this process, the return spring drives the push rod 440 to move toward the direction of the inclined slot, so that the push rod 440 retracts into the winding tube 441, which facilitates the dismantling and placement of the winding drum.

[0046] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
