Description

Technical Field

[0001] This utility model belongs to the field of cutting device technology, specifically a window cutting device for flexible circuit board cover film. Background Technology

[0002] Flexible printed circuit board (FPC) cover film typically refers to PI (polyimide) cover film, which is a polymer film made of polyimide material. PI cover film has excellent flexibility, capable of withstanding bending and folding of the circuit board without breaking or being damaged. A window cutting device for flexible printed circuit board (FPC) cover film is a device specifically designed to precisely cut windows of specific shapes and sizes into the cover film of the flexible circuit board. These windows are typically used to expose certain portions of the flexible circuit board for electrical connections, component mounting, or other functional requirements.

[0003] Because the shapes and sizes of the openings vary, the cutter heads need to be replaced frequently. However, replacing the cutter heads of existing cutting devices is very inconvenient, which increases the difficulty for operators and reduces work efficiency. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a window cutting device for flexible circuit board cover film, which effectively solves the problem that the replacement of the cutter head of the existing cutting device is very inconvenient, increases the difficulty of replacement for operators, and reduces work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a window-opening cutting device for flexible circuit board cover film, comprising a workbench, a placement platform fixedly installed at the center of the top of the workbench, an installation frame fixedly installed on one side of the top of the workbench, a hydraulic cylinder fixedly installed on the top of the installation frame, the transmission end of the hydraulic cylinder extending into the interior of the installation frame and fixedly installed with an installation block, a slot being provided at the bottom of the installation block, an insert block being inserted into the interior of the slot, two locking holes being provided on the surface of the insert block, a cutting head being fixedly installed at the bottom of the insert block, positioning rods being fixedly installed at the four corners of the top of the cutting head, positioning holes being provided at the four corners of the bottom of the installation block, the four positioning rods being inserted into the interior of the four positioning holes, two placement slots being provided on the rear side of the installation block, locking rods being inserted into the interior of the two placement slots, a support plate being fixedly installed on the upper part of the rear side of the installation block, a motor being fixedly installed at the bottom of the support plate, a transmission component being provided at the output end of the motor, the transmission component being connected to the two locking rods in a transmission manner, when the motor is running, power is output to the two locking rods, causing the two locking rods to insert into the two locking holes for limited installation.

[0006] Preferably, the transmission assembly includes a shaft, which is fixedly installed at the output end of the motor. A bushing is rotatably mounted on the surface of the shaft. The surface of the bushing is fixedly connected to the rear side of the mounting block via a support rod. A first bevel gear is fixedly installed at the bottom of the shaft.

[0007] Preferably, a second bevel gear is meshed with one side of the surface of the first bevel gear, a rotating rod is fixedly installed in the middle of the second bevel gear, and pusher wheels are fixedly installed at both ends of the rotating rod. Positioning frames are rotatably installed on the sides of the two pusher wheels that are far apart from each other, and one end of each positioning frame is fixedly connected to the rear side of the mounting block.

[0008] Preferably, one end of each of the two pushing wheels near the mounting block is tightly attached to a pad, one side of each pad is fixedly connected to one end of each of the two clamping rods, and springs are fitted onto the surface of each clamping rod, with the two ends of each spring fixedly connected to the rear side of the mounting block and the two pads, respectively.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When installing the cutter head, the operator inserts the insert block at the top of the cutter head into the slot of the mounting block, and at the same time inserts the four positioning rods into the four positioning holes. Then the operator starts the motor to run in the forward direction. When the motor runs in the forward direction, it drives the shaft to rotate along the inside of the bushing. When the shaft rotates, it drives the second bevel gear to rotate through the first bevel gear. When the second bevel gear rotates, it drives the two pushing wheels to rotate along the two positioning frames through the rotating rod. When the two pushing wheels rotate, they push the two locking rods to move through the two pads, and at the same time squeeze the two springs. When the two locking rods move, they will be locked into the two locking holes on the insert block for limiting, thereby quickly completing the installation of the cutter head.

[0010] During disassembly, the operator starts the motor and reverses its rotation. This reverse rotation causes the two pushing wheels to rotate and release the two pads. The spring force of the two springs then pushes the two locking rods out of the two locking holes, releasing the limiting mechanism and quickly completing the disassembly. During use, the operator places the covering film on the placement table and uses an external clamping tool to position it. The operator then activates the hydraulic cylinder to move the mounting block downwards. As the mounting block moves downwards, the cutting head moves downwards to perform the window cutting. This makes changing the cutting head of this device very convenient, reducing the difficulty for the operator and improving work efficiency. Attached Figure Description

[0019] 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.

[0020] Depend on Figures 1 to 5The present invention includes a workbench 1, a placement platform 2 fixedly installed at the center of the top of the workbench 1, a mounting bracket 3 fixedly installed on one side of the top of the workbench 1, a hydraulic cylinder 4 fixedly installed on the top of the mounting bracket 3, the transmission end of the hydraulic cylinder 4 extending into the interior of the mounting bracket 3 and fixedly installed with a mounting block 5, a slot 9 opening at the bottom of the mounting block 5, a plug 7 inserted into the slot 9, two locking holes 8 opening on the surface of the plug 7, a cutter head 6 fixedly installed at the bottom of the plug 7, and positioning rods 10 fixedly installed at the four corners of the top of the cutter head 6, and the bottom of the mounting block 5... The four corners of the mounting block 5 are provided with positioning holes 11, and four positioning rods 10 are inserted into the four positioning holes 11. Two placement slots 12 are provided on the rear side of the mounting block 5, and two locking rods 13 are inserted into the two placement slots 12. A support plate 16 is fixedly installed on the upper part of the rear side of the mounting block 5, and a motor 17 is fixedly installed on the bottom of the support plate 16. The output end of the motor 17 is provided with a transmission component, which is connected to the two locking rods 13. When the motor 17 is running, it outputs power to the two locking rods 13, so that the two locking rods 13 are inserted into the two locking holes 8 for limited installation.

[0021] When installing the cutter head 6, the operator inserts the insert block 7 at the top of the cutter head 6 into the slot 9 of the mounting block 5, and at the same time inserts the four positioning rods 10 into the four positioning holes 11. Then the operator starts the motor 17 to run in the forward direction. When the motor 17 runs in the forward direction, it drives the transmission component to run in the forward direction. When the transmission component runs in the forward direction, it pushes the two locking rods 13 into the two locking holes 8 on the insert block 7 for limiting, thereby quickly completing the installation of the cutter head 6.

[0022] During disassembly, the operator starts motor 17 to run in reverse. When motor 17 runs in reverse, it drives the transmission component to run in reverse. When the transmission component runs in reverse, it drives the two locking rods 13 to disengage from the two locking holes 8, thus releasing the limit and quickly completing the disassembly. During use, the operator places the covering film on the placement table 2 and uses an external clamping tool to position the covering film. Then, the operator starts hydraulic cylinder 4 to move mounting block 5 down. When mounting block 5 moves down, it drives the cutter head 6 down to perform window cutting. This makes it very convenient to replace the cutter head 6 of this cutting device, thereby reducing the difficulty of replacement for the operator and improving work efficiency.

[0023] The transmission assembly includes a shaft 18, which is fixedly installed at the output end of the motor 17. A bushing 19 is rotatably mounted on the surface of the shaft 18. The surface of the bushing 19 is fixedly connected to the rear side of the mounting block 5 via a support rod 20. A first bevel gear 21 is fixedly mounted at the bottom of the shaft 18. A second bevel gear 22 is meshed with one side of the surface of the first bevel gear 21. A rotating rod 23 is fixedly mounted in the middle of the second bevel gear 22. Pushing wheels 24 are fixedly mounted at both ends of the rotating rod 23. Positioning frames 25 are rotatably mounted on the sides of the two pushing wheels 24 that are far apart from each other. One end of each positioning frame 25 is fixedly connected to the rear side of the mounting block 5. A pad 15 is tightly attached to the end of each of the two pushing wheels 24 near the mounting block 5. One side of each pad 15 is fixedly connected to one end of each of the two clamping rods 13. Springs 14 are sleeved on the surface of each of the two clamping rods 13. The two ends of each spring 14 are fixedly connected to the rear side of the mounting block 5 and the two pads 15, respectively.

[0024] During installation, the operator starts the motor 17 to run in the forward direction. When the motor 17 runs in the forward direction, it drives the shaft 18 to rotate along the inside of the bushing 19. When the shaft 18 rotates, it drives the second bevel gear 22 to rotate through the first bevel gear 21. When the second bevel gear 22 rotates, it drives the two pushing wheels 24 to rotate along the two positioning frames 25 through the rotating rod 23. When the two pushing wheels 24 rotate, they push the two clamping rods 13 to move through the two pads 15, and at the same time squeeze the two springs 14.

[0025] During disassembly, the operator starts the motor 17 to run in reverse. When the motor 17 runs in reverse, it will drive the two push rollers 24 to rotate and release the two pads 15. Then, under the elastic force of the two springs 14, the two locking rods 13 will move and reset.
