Description

Technical Field

[0001] This invention belongs to the field of cutting device technology, and specifically relates to an insulating film cutting device. Background Technology

[0002] An insulating film is a thin film that ensures good electrical insulation. This film should have high resistivity and breakdown field strength, while its electronic structure is characterized by a large bandgap. For high-frequency insulation, the material also needs to have low dielectric loss.

[0003] Commonly used organic insulating film materials include polyimide, polyethylene, polyvinylidene fluoride, and polytetrafluoroethylene.

[0004] During the production process, the insulating film needs to be cut to the required length to fit subsequent processing. Currently, the common method is to manually measure the quantity and then use relevant tools for manual cutting, which is slow and wastes manpower. However, the current automated cutting equipment has a problem: it cannot accurately position and fix the length of the film, which causes the film to deform under force during cutting, resulting in uneven lengths of the finished products and making it difficult to position the length of the film in subsequent processes, leading to continuous errors. Summary of the Invention

[0005] To address the problems raised in the background art, the objective of this invention is to provide an insulating film cutting device. To achieve this objective, the technical solution adopted by this invention is as follows:

[0006] An insulating film cutting device includes a frame, the frame being equipped with a hanging port, the frame being equipped with two sets of guide rollers, and the frame being symmetrically equipped with a set of upper slide rails and a set of lower slide rails;

[0007] An upper lead screw is rotatably installed inside the upper slide rail. A first motor is connected to the power end of the upper lead screw. A horizontal moving mechanism is installed on the upper slide rail in conjunction with the upper lead screw. A lower lead screw is rotatably installed inside the lower slide rail. A second motor is connected to the power end of the lower lead screw. A cooperating moving mechanism is installed on the lower slide rail in conjunction with the lower lead screw. Both the horizontal moving mechanism and the cooperating moving mechanism are equipped with clamping mechanisms.

[0008] The horizontal moving mechanism includes a horizontal moving mounting strip slidably installed in the upper slide rail, the horizontal moving mounting strip being threadedly connected to the upper lead screw, the horizontal moving mounting strip having a first slide groove, a first lead screw being rotatably installed in the first slide groove, a first synchronous motor being installed at the power end of the first lead screw, and a clamping mechanism being slidably installed in the first slide groove, the clamping mechanism being threadedly matched to the first lead screw.

[0009] The mating moving mechanism includes a mating moving mounting strip slidably installed in the lower slide rail, the mating moving mounting strip being threadedly connected to the lower lead screw, the mating moving mounting strip being equipped with a first telescopic cylinder, the output end of the first telescopic cylinder being connected to a moving block, the moving block being provided with a second slide groove, a second lead screw being rotatably installed in the second slide groove, a second synchronous motor being installed at the power end of the second lead screw, and the clamping mechanism being slidably installed in the second slide groove, the clamping mechanism being threadedly matched to the second lead screw;

[0010] The clamping mechanism includes a displacement mounting plate, on which a parallel finger cylinder is mounted. A gearbox is mounted on the longitudinal finger side of one of the parallel finger cylinders. An upper gear and a lower gear that mesh with each other are rotatably mounted inside the gearbox. An upper clamping roller is connected to the shaft of the lower gear, and a power motor is connected to the shaft of the upper gear. A rectangular block is mounted on the other finger of the parallel finger cylinder, and a lower clamping roller with specifications and dimensions matching the upper clamping roller is mounted on the rectangular block.

[0011] The frame is equipped with a second telescopic cylinder, and the output end of the second telescopic cylinder is connected to a cutter.

[0012] Furthermore, one of the two symmetrically arranged upper clamping rollers on the same axis is connected to a hexagonal insert at its end, and the other upper clamping roller is provided with a hexagonal slot whose position, specifications, and dimensions match the hexagonal insert. This design enables the upper clamping rollers to dock, thereby achieving synchronous rotation of the two upper clamping rollers.

[0013] Furthermore, the distance between the side end face of the upper clamping roller and the finger end face of the parallel finger cylinder is two centimeters. This design allows for selection of whether to use the parallel finger cylinder or the upper clamping roller to clamp the insulating film by moving this distance.

[0014] Furthermore, the horizontal plane where the lowest point of the outer circle of the upper clamping roller is located is on the same horizontal plane as the horizontal plane of the finger clamping surface of the parallel finger cylinder. With this design, it is not necessary to set the clamping size separately when using the fingers of the parallel finger cylinder for clamping or when using the upper and lower clamping rollers for clamping, and the clamping of the two will not interfere with each other.

[0015] Furthermore, a connecting rod connects the upper slide rail and the lower slide rail. This design ensures the mutual support between the upper and lower slide rails and provides good anti-vibration and displacement effects.

[0016] Furthermore, both the upper slide rail and the lower slide rail are provided with mounting grooves, and proximity switches are installed in the mounting grooves. This design enables distance control and achieves the purpose of length adjustment.

[0017] Furthermore, both the cutter and the moving block are connected to guide rods, and the corresponding frame and the mating moving mounting strip are provided with guide holes. This design ensures that the cutter and the moving block move smoothly.

[0018] Furthermore, the movable mounting strip is equipped with a mounting bracket, and the first telescopic cylinder is mounted on the mounting bracket. This design ensures that the first telescopic cylinder is securely fixed, thereby ensuring the accuracy of the telescopic length of the movable block.

[0019] Furthermore, the displacement mounting plate is equipped with a guide rail, and the power motor is slidably mounted on the guide rail. This design ensures that the lifting and lowering of the power motor is smooth.

[0020] Furthermore, the gearbox, the upper gear, and the lower gear are all configured with multiple specifications, and the corresponding upper clamping roller and lower clamping roller are also configured with multiple specifications. This design can accommodate the installation and use of upper and lower clamping rollers with different diameters.

[0021] The beneficial effects of using the present invention are as follows:

[0022] The structural design of this invention enables automated fixed-length cutting of insulating films. During cutting, the cutting position of the insulating film is fixed, preventing deformation of the insulating film due to cutting force. It also ensures that the length of the insulating film to be cut subsequently is not affected by the cutting of the previous insulating film, thus guaranteeing production quality and saving labor costs.

[0035] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] like Figures 1-6 As shown, an insulating film cutting device of the present invention includes a frame 1, a hanging port 2 installed on the frame 1, two sets of guide rollers 3 installed on the frame 1, and a set of upper slide rails 4 and a set of lower slide rails 5 symmetrically installed on the frame 1.

[0037] An upper lead screw 6 is rotatably installed inside the upper slide rail 4. The power end of the upper lead screw 6 is connected to a first motor 7. A horizontal moving mechanism 8 is installed in the upper slide rail 4 in conjunction with the upper lead screw 6. A lower lead screw 9 is rotatably installed inside the lower slide rail 5. The power end of the lower lead screw 9 is connected to a second motor 10. A cooperating moving mechanism 11 is installed in the lower slide rail 5 in conjunction with the lower lead screw 9. Both the horizontal moving mechanism 8 and the cooperating moving mechanism 11 are equipped with clamping mechanisms 12.

[0038] The horizontal moving mechanism 8 includes a horizontal moving mounting bar 81 that is slidably installed in the upper slide rail 4. The horizontal moving mounting bar 81 is threadedly connected to the upper lead screw 6. The horizontal moving mounting bar 81 is provided with a first slide groove 82. A first lead screw 83 is rotatably installed in the first slide groove 82. A first synchronous motor 84 is installed at the power end of the first lead screw 83. A clamping mechanism 12 is slidably installed in the first slide groove 82 and threadedly matched to the first lead screw 83.

[0039] The moving mechanism 11 includes a moving mounting strip 111 slidably installed in the lower slide rail 5, the moving mounting strip 111 being threadedly connected to the lower lead screw 9, a first telescopic cylinder 112 being installed on the moving mounting strip 111, a moving block 113 being connected to the output end of the first telescopic cylinder 112, a second slide groove 114 being provided on the moving block 113, a second lead screw 115 being rotatably installed in the second slide groove 114, a second synchronous motor 116 being installed on the power end of the second lead screw 115, and a clamping mechanism 12 being slidably installed in the second slide groove 114 and threadedly matched to the second lead screw 115.

[0040] The clamping mechanism 12 includes a displacement mounting plate 121, on which a parallel finger cylinder 122 is mounted. A gearbox 123 is mounted on one of the longitudinal finger sides of the parallel finger cylinder 122. An upper gear 124 and a lower gear 125 are rotatably mounted inside the gearbox 123. An upper clamping roller 126 is connected to the shaft of the lower gear 125, and a power motor 127 is connected to the shaft of the upper gear 124. A rectangular block 128 is mounted on the other finger of the parallel finger cylinder 122, and a lower clamping roller 129 with dimensions matching the upper clamping roller 126 is mounted on the rectangular block 128.

[0041] The frame 1 is equipped with a second telescopic cylinder 13, and the output end of the second telescopic cylinder 13 is connected to a cutter 14.

[0042] In this embodiment, when using an insulating film cutting device, the two ends of the roller containing the insulating film to be cut are placed on the hanging opening 2. Then, one end is pulled out, passes between the guide rollers 3, and after passing through the horizontal moving mechanism 8 and the cooperating moving mechanism 11, it is clamped by the subsequent unloading equipment. It should be noted that the subsequent unloading equipment is not limited and is not the main technology protected in this application. It can be an ordinary winding roller or a related insulating film unloading device, which can clamp and pull the tail end of the insulating film to ensure that the insulating film is in a taut state.

[0043] Then, the maximum distance that the horizontal moving mechanism 8 and the cooperating moving mechanism 11 can move to is the length of the insulating film to be cut.

[0044] Both the horizontal moving mechanism 8 and the cooperating moving mechanism 11 are equipped with a clamping mechanism 12. The clamping mechanisms 12 installed on both have the same structure, the same operation mode, and the same effect. They use the fingers of the parallel finger cylinder 122 to clamp the two sides of the insulating film or only use the upper clamping roller 126 and the lower clamping roller 129 to clamp the insulating film. Depending on the needs, the power motor 127 is used to pull the insulating film.

[0045] The main operation involves the switching and coordination of the horizontal moving mechanism 8 and the cooperating moving mechanism 11. Specifically, the second synchronous motor 116 on the cooperating moving mechanism 11 operates, driving the mounting brackets 117 on both sides to move relative to each other until the fingers of the parallel finger cylinder 122 can grip the edge of the insulating film. The parallel finger cylinder 122 then operates, gripping the insulating film. During this operation, the upper clamping roller 126 and lower clamping roller 129 on the cooperating moving mechanism 11 also grip the insulating film laterally. At this time, the fingers of the parallel finger cylinder 122 on the horizontal moving mechanism 8 do not grip the insulating film; only the upper clamping roller 126 and lower clamping roller 129 on the horizontal moving mechanism 8 grip the insulating film. Under this gripping method, when the cooperating moving mounting strip 111 is engaged by the second motor 10 and the lead screw 9... When the movement proceeds, the insulating film can be pulled out from the insulating film roller. The distance that the moving mounting strip 111 moves horizontally is the length pulled out. When the moving mounting strip 111 moves to the set position, the parallel finger cylinder 122 on the clamping mechanism 12 on the horizontal moving mechanism 8 is released. At the same time, the first synchronous motor 84 runs, driving the displacement mounting plate 121 connected to it to move relative to each other, so that the fingers of the parallel finger cylinder 122 can clamp to both sides of the insulating film and then stop. The parallel finger cylinder 122 runs, using the fingers to clamp the insulating film. At this time, the moving mechanism 11 and the horizontal moving mechanism 8 have achieved clamping of the insulating film at four positions. Therefore, the insulating film will not have the problem of force displacement during subsequent cutting. The second telescopic cylinder 13 runs, driving the cutter 14 to move downward to complete the cutting of the insulating film.

[0046] After one cut is completed, the clamping mechanism 12 on the moving mechanism 11 completely releases the insulating film, while the clamping mechanism 12 on the horizontal moving mechanism 8 maintains its clamping of the insulating film. Then, the second synchronous motor 116 runs, driving the clamping mechanisms 12 on both sides to move in opposite directions. The clamping mechanism 12 on the moving mechanism 11 then disengages from the insulating film. Then, the first telescopic cylinder 112 runs, driving the moving block 113 downwards until the horizontal moving mechanism 8 and the moving mechanism 11 no longer interfere with each other's movements. Then, the second motor 10 runs, and the lower lead screw 9 drives the moving mechanism 11 towards the horizontal moving mechanism 8 until it reaches the rear of the horizontal moving mechanism 8. Then, the second synchronous motor 10... A telescopic cylinder 112 operates, driving the moving block 113 to rise until the clamping mechanism 12 can clamp the insulating film. Then, the upper clamping roller 126 and lower clamping roller 129 of the clamping mechanism 12 on the cooperating moving mechanism 11 clamp the insulating film. The horizontal moving mechanism 8 starts to move horizontally with the cooperation of the first motor 7 and the upper lead screw 6, realizing the stretching of the insulating film. It stops after reaching the specified length. Then, after the clamping mechanism 12 on the cooperating moving mechanism 11 releases the insulating film, the fingers of the parallel finger cylinder 122 are used to clamp the insulating film, thus completing the clamping of the insulating film in four places. Then, the horizontal moving mechanism 8 and the cooperating moving mechanism 11 drive the insulating film to the underside of the cutter 14 to start another cut.

[0047] After the insulating film is cut into two sections of the required length, the front and rear positions of the horizontal moving mechanism 8 and the cooperating moving mechanism 11 are swapped. This swapping of their original positions constitutes one cycle. The swapping method is as follows: the clamping mechanism 12 on the cooperating moving mechanism 11 keeps clamping the insulating film, while the clamping mechanism 12 on the horizontal moving mechanism 8 releases the cut insulating film. The first telescopic cylinder 112 operates, keeping the insulating film clamped and lowering it together. The horizontal moving mechanism 8 returns to its original position, and the cooperating moving mechanism 11 pulls the insulating film to the front of the horizontal moving mechanism 8 and then moves it to the height position of the horizontal moving mechanism 8, thus completing the swapping. At this time, the clamping mechanism 12 on the horizontal moving mechanism 8 can achieve the clamping of the insulating film during the preparation of one cut.

[0048] The operation of the power motor 127 is as follows: when the required cutting length of the insulating film is greater than the maximum length of the upper slide rail 4 or the lower slide rail 5, the first motor 7 or the second motor 10 is not running or is running to the limit position. The operation of the power motor 127 can cooperate with the upper clamping roller 126 and the lower clamping roller 129 to directly pull the insulating film to achieve the required length and to perform clamping and cutting.

[0049] Preferably, one of the two symmetrically arranged upper clamping rollers 126 on the same axis is connected to a hexagonal insert 1210 at its end, and the other upper clamping roller 126 is provided with a hexagonal slot 1211 whose position and size match the hexagonal insert 1210. This design enables the upper clamping rollers 126 to dock, thereby enabling the synchronous rotation of the two upper clamping rollers 126. In fact, the docking structure of the two can also be considered according to the specific situation.

[0050] Preferably, the distance between the side end face of the upper clamping roller 126 and the finger end face of the parallel finger cylinder 122 is two centimeters. With this design, by moving this distance, it is possible to choose whether to use the parallel finger cylinder 122 or the upper clamping roller 126 to clamp the insulating film. In fact, the distance between the side end face of the upper clamping roller 126 and the finger end face of the parallel finger cylinder 122 can also be considered according to the specific situation.

[0051] Preferably, the horizontal plane of the lowest point of the outer circle of the upper clamping roller 126 is at the same level as the horizontal plane of the finger clamping surface of the parallel finger cylinder 122. With this design, it is not necessary to set the clamping size separately when using the fingers of the parallel finger cylinder 122 for clamping or when using the upper clamping roller 126 and the lower clamping roller 129 for clamping, and the clamping of the two will not interfere with each other. In fact, the maximum diameter of the upper clamping roller 126 can also be considered according to the specific situation.

[0052] Preferably, a connecting rod 15 is connected between the upper slide rail 4 and the lower slide rail 5. This design ensures the mutual support between the upper slide rail 4 and the lower slide rail 5 and has a good anti-vibration displacement effect. In fact, the connection structure between the upper slide rail 4 and the lower slide rail 5 can also be considered according to the specific situation.

[0053] Preferably, both the upper slide rail 4 and the lower slide rail 5 are provided with mounting grooves 16, and a proximity switch 17 is installed in the mounting groove 16. This design enables distance control and achieves the purpose of length adjustment. In fact, distance control measures can also be considered according to specific circumstances.

[0054] Preferably, both the cutter 14 and the moving block 113 are connected to guide rods 18, and the corresponding frame 1 and the cooperating moving mounting strip 111 are provided with guide holes 19. This design ensures that the cutter 14 and the moving block 113 move smoothly. In fact, a structure that ensures the smooth movement of the cutter 14 and the moving block 113 can also be considered according to the specific situation.

[0055] Preferably, the movable mounting strip 111 is fitted with a mounting bracket 117, and the first telescopic cylinder 112 is mounted on the mounting bracket 117. This design ensures that the first telescopic cylinder 112 is securely fixed, thereby ensuring the accuracy of the telescopic length of the movable block 113. In fact, the mounting structure of the first telescopic cylinder 112 can also be considered according to the specific situation.

[0056] The preferred displacement mounting plate 121 is equipped with a guide rail 1212, and the power motor 127 is slidably mounted on the guide rail 1212. This design ensures that the lifting and lowering of the power motor 127 is smooth. In fact, a structure that ensures the smooth lifting and lowering of the power motor 127 can also be considered according to specific circumstances.
