Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for protective film production, and in particular to a correction device for processing electronic protective films. Background Technology

[0002] Against the backdrop of the rapid development of the electronics and information industry, electronic protective films, as key protective materials for precision electronic components such as displays and circuit boards, directly affect the quality stability of end products due to their processing precision and production efficiency. The processing of electronic protective films requires continuous production through multiple steps, including unwinding, coating, and cutting. However, due to factors such as tension fluctuations in the substrate itself and equipment transmission errors, the protective film is prone to deviation. If not corrected in time, this can lead to subsequent problems such as dimensional deviations in cutting and uneven coating layers, and in severe cases, even material scrap. Therefore, deviation correction devices have become an indispensable core component of electronic protective film production lines.

[0003] Existing web guiding devices, such as the web guiding device for protective film production disclosed in CN220449278U, use a worm gear to drive the web guiding roller to move, thereby causing the misaligned electronic protective film to return to its original position. However, the pressure roller above the web guiding roller is fixed and its height cannot be adjusted. When changing rolls or installing protective film for the first time on the production line, the operator needs to pull the protective film substrate from the unwinding mechanism to the web guiding device and accurately pass it through the gap between the pressure roller and the support roller below. Since the pressure roller cannot move, the distance between it and the support roller is fixed, and the installation space at both ends of the pressure roller is narrow, the operator needs to repeatedly adjust the traction angle and tension of the protective film to smoothly guide the substrate between the two rollers. The entire installation process is time-consuming, significantly increasing the difficulty for a single person to operate. It often requires the cooperation of multiple people, which seriously affects the roll changing efficiency of the production line and leads to prolonged equipment downtime. Utility Model Content

[0004] The purpose of this invention is to solve the shortcomings of existing pressure rollers, which cannot be adjusted in position, resulting in a long installation process for the substrate to be smoothly introduced between the two rollers, and significantly increasing the difficulty of single-person operation. Therefore, a correction device for electronic protective film processing is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A correction device for processing electronic protective film includes a worktable, a correction device, and an edge pressing device. The top of the worktable is fixedly connected to a pair of symmetrically distributed fixed sides. The outer wall of the fixed sides is fixedly connected to a mounting platform. A servo motor is fixedly mounted on the mounting platform. The servo motor is connected to a pressure roller through a synchronous height adjustment structure. An adjustment mechanism for adjusting the gap between the edge pressing devices is provided below the edge pressing device.

[0007] Preferably, the synchronous height adjustment structure includes:

[0008] A chute is formed on the opposite side of the fixed edge. A synchronizing screw is rotatably connected to the bottom of the inner wall of the chute. The top of the synchronizing screw passes through the top of the fixed edge and is fixedly connected to a bevel gear.

[0009] Preferably, the synchronous height adjustment structure further includes:

[0010] A second bevel gear is rotatably connected to the inner wall of the opposite side of the fixed edge. A transmission rod is fixedly connected between the two bevel gears. The bevel gear two closer to the servo motor is fixedly connected to the output end of the servo motor. The first bevel gear and the second bevel gear mesh with each other.

[0011] Preferably, the synchronous screw is threadedly connected to a movable block, the movable block is rotatably connected to both ends of the pressure roller, the movable block is slidably connected to the inner wall of the slide groove, and the slide groove is T-shaped.

[0012] Preferably, the adjustment mechanism includes a slot on the top of the workbench, a drive motor is fixedly installed on the bottom of the workbench, a coarse screw is fixedly connected to the output end of the drive motor, a lifting plate is slidably connected to the inner wall of the slot, and an internal threaded sleeve is fixedly connected to the bottom of the lifting plate.

[0013] Preferably, the coarse screw is threadedly connected to the internal thread sleeve, and the pressing device is disposed on the top of the lifting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. In use, the servo motor drives the second bevel gear to rotate. Through the meshing transmission between the first and second bevel gears, the synchronous screws on both sides rotate synchronously, thereby driving the moving block to rise and fall stably along the slide groove, achieving precise and synchronous adjustment of the pressure roller height. This adjustment method eliminates the need for manual adjustment of the two pressure rollers, significantly shortening the installation time between the two rollers for substrate introduction. It also avoids the problem of inconsistent heights of the two pressure rollers during manual adjustment. A single person can easily complete the pressure roller position adjustment and substrate introduction operation, significantly reducing the difficulty of operation and improving the convenience of the processing flow.

[0016] 2. In use, the adjustment mechanism of this invention uses a drive motor to rotate a coarse screw. Through the threaded engagement of the coarse screw and the inner threaded sleeve, the lifting plate is driven to rise and fall along the groove, thereby adjusting the height of the pressing device and achieving precise adjustment of the gap between the pressing devices. Whether the electronic protective film substrate is thin or thick, adjusting the height of the pressure roller and the gap between the pressing devices ensures stable transmission and precise correction of the substrate during processing. This breaks the limitations of traditional fixed structures on substrate thickness, significantly enhancing the versatility and applicability of the device. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 A correction device for processing electronic protective film includes a worktable 1, a correction device 2 and an edge pressing device 3, which work together to realize the conveying, correction and edge pressing of the processed material.

[0024] Both the correction device 2 and the edge pressing device 3 are existing technologies used in this field. The correction device 2 is manually driven to rotate the small gear plate. The small gear plate rotates many times before the large gear plate drives the worm to rotate a certain angle. The worm wheel, which meshes with the worm, drives the threaded rod, which is fixedly connected to itself, to rotate a certain angle. The threaded block, which is threadedly connected to the threaded rod, drives the correction roller to move through the corresponding second support ear. It works together with the cooperating roller to achieve fine adjustment during the production and winding process of the protective film.

[0025] The edge pressing device 3 effectively presses the protective film by means of a servo motor, rotating rod, threaded sleeve, and electric telescopic rod and pressure roller, preventing displacement and wrinkling.

[0026] The workbench 1 serves as the basic load-bearing structure of the equipment, with a pair of symmetrically distributed fixed edges 4 fixedly connected to its top. The fixed edges 4 provide stable support for the subsequent installation and adjustment of the pressure rollers 7. A mounting platform 5 is fixedly connected to the outer wall of the fixed edges 4, and a servo motor 6 is fixedly installed on the mounting platform 5. The servo motor 6 serves as a power source and is connected to the pressure rollers 7 through a synchronous height adjustment structure, which can drive the pressure rollers 7 to achieve synchronous height adjustment to adapt to the edge pressing requirements of materials of different thicknesses. An adjustment mechanism 8 is provided below the edge pressing devices 3 to adjust the gap between the edge pressing devices 3. The gap between the edge pressing devices 3 can be precisely controlled through the adjustment mechanism 8 to ensure the edge pressing quality.

[0027] The synchronous height adjustment structure is used to achieve synchronous lifting and lowering of both ends of the pressure roller 7, ensuring that the pressure roller 7 remains horizontal during the adjustment process. Its specific structure includes the following parts:

[0028] Slide 9: A slide 9 is provided on the opposite side of the fixed edge 4. The slide 9 is T-shaped. The T-shaped structure design can effectively limit the sliding direction of the moving block 14, prevent the moving block 14 from shifting or falling off during the sliding process, and provide a stable sliding track for the moving block 14.

[0029] Synchronizing screw 10 and bevel gear 13: A synchronizing screw 10 is rotatably connected to the bottom of the inner wall of the slide groove 9. The top of the synchronizing screw 10 passes through the top of the fixed edge 4 and is fixedly connected to bevel gear 13. The synchronizing screw 10 is threadedly engaged with the subsequent moving block 14. When the synchronizing screw 10 rotates, it can drive the moving block 14 to move up and down along the slide groove 9. Bevel gear 13 is a key component for power transmission, used to receive power from bevel gear 11 and drive the synchronizing screw 10 to rotate.

[0030] Bevel gear 11 and transmission rod 12: Bevel gear 11 is rotatably connected to the inner wall on the opposite side of the fixed edge 4. Transmission rod 12 is fixedly connected between bevel gears 11. The bevel gear 11 closer to the servo motor 6 is fixedly connected to the output end of the servo motor 6, and bevel gear 13 meshes with bevel gear 11. When the servo motor 6 starts, its output end drives the bevel gear 11 connected to it to rotate. Through the transmission action of transmission rod 12, the bevel gears 11 on both sides can rotate synchronously, thereby driving the bevel gear 13 meshing with it to rotate synchronously, and finally realizing the synchronous rotation of the synchronous screws 10 on both sides.

[0031] Moving block 14: The synchronous screw 10 is threadedly connected to the moving block 14, which is rotatably connected to both ends of the pressure roller 7 and slidably connected to the inner wall of the slide groove 9. When the synchronous screw 10 rotates synchronously, the moving block 14 slides stably along the slide groove 9 under the action of the thread, thereby driving both ends of the pressure roller 7 to rise and fall synchronously, realizing synchronous adjustment of the height of the pressure roller 7.

[0032] The adjusting mechanism 8 is used to precisely adjust the gap between the pressing devices 3 to meet the pressing requirements of materials of different specifications. Its specific structure is as follows:

[0033] Slot 16 and drive motor 15: A slot 16 is provided on the top of the worktable 1, which provides space for the lifting plate 19 to rise and fall; a drive motor 15 is fixedly installed at the bottom of the worktable 1, which serves as the power source for the adjustment mechanism 8 and provides power for the gap adjustment of the pressing device 3.

[0034] The coarse screw 17 and the internal threaded sleeve 18: The output end of the drive motor 15 is fixedly connected to the coarse screw 17, and the inner wall of the slot 16 is slidably connected to the lifting plate 19. The bottom of the lifting plate 19 is fixedly connected to the internal threaded sleeve 18, and the coarse screw 17 and the internal threaded sleeve 18 are threadedly connected. When the drive motor 15 starts, its output end drives the coarse screw 17 to rotate. Since the internal threaded sleeve 18 is threadedly engaged with the coarse screw 17 and the lifting plate 19 is restricted from rotating by the slot 16, the rotation of the coarse screw 17 is converted into the up and down movement of the internal threaded sleeve 18, which in turn drives the lifting plate 19 to slide up and down along the slot 16.

[0035] Installation of the edge pressing device 3: The edge pressing device 3 is located on the top of the lifting plate 19. When the lifting plate 19 slides up and down, it will drive the edge pressing device 3 to move up and down synchronously, thereby adjusting the gap between the edge pressing devices 3. By controlling the forward and reverse rotation and the number of rotations of the drive motor 15, the lifting height of the lifting plate 19 can be precisely controlled, thereby precisely adjusting the gap of the edge pressing device 3 and ensuring the accuracy and stability of the edge pressing operation.

[0036] It should be noted that the specific model and specifications of the servo motor 6 and drive motor 15 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here. Both can be powered by external devices and controlled to turn on and off.

[0037] Working principle:

[0038] In actual use, when it is necessary to adjust the height of the pressure roller 7 to match the material thickness, the servo motor 6 is started. Through the transmission of bevel gear 13, bevel gear 2 11 and transmission rod 12, the synchronous screws 10 on both sides are driven to rotate synchronously, so that the moving block 14 drives the pressure roller 7 to rise and fall synchronously to the appropriate height. When it is necessary to adjust the gap of the pressing device 3, the drive motor 15 is started. Through the cooperation of the coarse screw 17 and the inner threaded sleeve 18, the lifting plate 19 and the pressing device 3 are driven to move up and down, so as to achieve precise adjustment of the gap. The whole equipment is easy to operate and has high adjustment accuracy, which can effectively improve the efficiency and quality of pressing operation.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
