Description

Technical Field

[0001] This utility model relates to the field of die-cutting equipment technology, and in particular to a planar die-cutting device for light-shielding film. Background Technology

[0002] In the field of precision machining of light-shielding film materials, especially in the manufacture of light-shielding film parts used inside electronic products to prevent light interference, flat die-cutting equipment is usually required.

[0003] In some traditional die-cutting devices, the hydraulic cylinder driving the die structure generates a huge instantaneous impact force during operation. This impact can easily cause the support structure to vibrate, which not only affects the die-cutting accuracy but may also reduce the life of the die and the equipment. In order to solve the above problems, this utility model provides a planar die-cutting device for light-shielding film. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a planar die-cutting device for light-shielding film.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A planar die-cutting device for light-shielding film includes a worktable. Support rods are fixedly connected to the four corners of the upper surface of the worktable. A top seat is fixedly connected to the upper end of each of the four support rods. An installation groove is formed in the middle of the upper surface of the top seat. A hydraulic cylinder is fixedly installed inside the installation groove. A die-cutting structure is fixedly connected to the telescopic end of the hydraulic cylinder. Connecting plates are fixedly connected to both sides of the die-cutting structure. Limiting rods are fixedly connected to both ends of the upper surface of the connecting plates. Protective components are fixedly connected to the upper ends of the four limiting rods. A feeding rack is fixedly connected to the front of the worktable, and an output rack is fixedly connected to the back of the worktable. A power component is fixedly connected to the upper ends of both the feeding rack and the output rack.

[0006] As a further improvement of this utility model, the protective component includes a top block fixedly connected to the upper end of four limiting rods, a protective spring fixedly connected to the lower end of the top block, a collar fixedly connected to the lower end of the protective spring, the protective spring and the collar both being sleeved on the surface of the limiting rods, and limiting grooves adapted to the limiting rods are provided at the four corners of the upper surface of the top block.

[0007] As a further improvement of this utility model, the power assembly includes a mounting frame fixedly connected to the upper end of the feeding frame and the discharging frame. Two conveying rollers are rotatably connected inside the mounting frame via bearings. A protective shell is fixedly connected to one side of the mounting frame. Two transmission gears are rotatably connected inside the protective shell via bearings. The two transmission gears are respectively connected to the two conveying rollers and the two transmission gears mesh.

[0008] As a further improvement of this utility model, a servo motor is fixedly installed on the other side of the mounting frame, and the power end of the servo motor is fixedly connected to one of the feeding rollers through a coupling.

[0009] As a further improvement of this utility model, a lower mold is fixedly connected to the middle of the upper surface of the worktable.

[0010] As a further improvement of this utility model, a base is fixedly connected to the lower surface of the workbench.

[0011] The beneficial effects of this utility model are: By setting up protective components, during use, the die-cutting structure moves under the drive of the hydraulic cylinder. The limiting rod slides along the limiting groove to restrict the movement trajectory of the die-cutting structure. The top block applies force to the collar through the protective spring, which can buffer the impact force when the die-cutting structure moves downward. This not only protects the die-cutting structure and the lower die and extends the service life of the device, but also improves the stability of the die-cutting process and ensures the consistency of the light-shielding film die-cutting.

[0012] By setting up a power component, when in use, the servo motor is started to drive the feed rollers to rotate. In conjunction with the meshing transmission gears, the two feed rollers operate synchronously, which can stably transport the light-blocking film and ensure that the light-blocking film remains flat during the process of being transported from the feeding rack to the worktable and discharged through the discharge rack. This avoids conveying deviation from affecting the die-cutting accuracy, reduces the potential for failure during the conveying process, and ensures the continuity of the die-cutting operation.

Support rods 2 are fixedly connected to the four corners of the upper surface of the worktable 1. Top seats 3 are fixedly connected to the upper ends of the four support rods 2. An installation groove is opened in the middle of the upper surface of the top seat 3. A hydraulic cylinder 4 is fixedly installed inside the installation groove. A die-cutting structure 5 is fixedly connected to the telescopic end of the hydraulic cylinder 4. Connecting plates 6 are fixedly connected to both sides of the die-cutting structure 5. Limiting rods 7 are fixedly connected to both ends of the upper surface of the connecting plates 6. Protective components are fixedly connected to the upper ends of the four limiting rods 7.

A power component is fixedly connected to the upper ends of the feeding rack 8 and the discharging rack 9.

[0019] In this utility model, the protective component includes a top block 10 fixedly connected to the upper end of the four limiting rods 7. The top block 10 serves as the mounting carrier for the protective spring 11, providing stable support for the buffer structure. The lower end of the top block 10 is fixedly connected to the protective spring 11, which has elastic extension and contraction properties and can play a buffering role when the die-cutting structure 5 moves. The lower end of the protective spring 11 is fixedly connected to a collar 12, which can slide along the surface of the limiting rod 7 and cooperate with the protective spring 11 to realize the transmission of buffering force. The protective spring 11 and the collar 12 are both sleeved on the surface of the limiting rod 7. The four corners of the upper surface of the top seat 3 are provided with limiting grooves 13 that are adapted to the limiting rod 7. The limiting grooves 13 provide sliding guidance for the limiting rod 7 and ensure the accuracy of the moving trajectory of the limiting rod 7.

[0020] The power assembly includes a mounting frame 14 fixedly connected to the upper end of the feed rack 8 and the discharge rack 9. Inside the mounting frame 14, two conveying rollers 15 are rotatably connected via bearings. A protective shell 16 is fixedly connected to one side of the mounting frame 14. The protective shell 16 can block external dust and impurities, preventing them from entering the meshing point of the transmission gears 17 and affecting the transmission. Inside the protective shell 16, two transmission gears 17 are rotatably connected via bearings. The two transmission gears 17 are respectively connected to the two conveying rollers 15. The two transmission gears 17 mesh, and the meshing and cooperation ensure that the two conveying rollers 15 rotate synchronously in opposite directions, ensuring the conveying effect. A servo motor 18 is fixedly installed on the other side of the mounting frame 14. The power end of the servo motor 18 is fixedly connected to one of the conveying rollers 15 via a coupling. The servo motor 18 provides a stable power source for the rotation of the conveying roller 15.

[0021] A lower mold 19 is fixedly connected to the middle of the upper surface of the workbench 1. The lower mold 19 cooperates with the die-cutting structure 5 to provide a support reference for the die-cutting operation of the light-shielding film. A base 20 is fixedly connected to the lower surface of the workbench 1. The base 20 increases the contact area between the device and the ground, thereby improving the placement stability of the entire device.

[0022] When this utility model is in use, the servo motor 18 is started first, and then drives the corresponding feeding roller 15 to rotate through the coupling. The feeding roller 15 drives the connected transmission gear 17 to rotate. Since the two transmission gears 17 mesh, they drive the other feeding roller 15 to rotate synchronously in the opposite direction. The light-shielding film enters through the feeding frame 8 and is transported to the upper part of the lower mold 19 of the worktable 1 with the cooperation of the two feeding rollers 15. After the hydraulic cylinder 4 is started, its telescopic end pushes the die-cutting structure 5 to move downward. When the die-cutting structure 5 moves, it drives the connecting plate 6 and the limiting rod 7 to move synchronously. The limiting rod 7 slides along the limiting groove 13 of the top seat 3 and the top block 10 applies force to the collar 12 through the protective spring 11. The collar 12 compresses the protective spring 11 to achieve buffering. The die-cutting structure 5 and the lower mold 19 cooperate to complete the die-cutting operation of the light-shielding film.
