Description

Technical Field

[0001] This utility model relates to the field of punching devices, specifically to a protective film punching device that is easy to position. Background Technology

[0002] In the field of mobile phone screen protector manufacturing, punching is a key step to meet the requirements of specific mobile phone models, such as reserving holes for components like front-facing cameras and sensors.

[0003] Traditional punching devices often struggle to control the position and state of the screen protector during the punching process. When securing the screen protector, simple clamps or manual pressing are frequently used. This method easily leads to uneven stress on the screen protector during compression, causing it to tilt or twist. Once the screen protector tilts or twists, the punch head cannot be perpendicular to the intended position during punching, resulting in punching misalignment and low punching accuracy.

[0004] To address this issue, we propose a protective film perforation device that is easy to position. Utility Model Content

[0005] The purpose of this invention is to provide a protective film punching device that is easy to position, so as to solve the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective film punching device for easy positioning, comprising a base plate, two positioning plates fixedly disposed on the top two sides of the base plate, two parallel translation plates disposed between the two positioning plates, guide holes and internal threaded holes respectively opened on the outer walls of the two ends of the translation plates, the guide holes and internal threaded holes on the two translation plates being in opposite positions, synchronous threaded rods being screwed onto the inner walls of the two internal threaded holes, the outer walls of the synchronous threaded rods being clearance-fitted with the inner walls of the guide holes, knobs being fixedly disposed on the outer walls of the two ends of the synchronous threaded rods, and two strip-shaped sponge columns being fixedly disposed on the outer walls of corresponding sides of the two translation plates, with extrusion grooves disposed between the strip-shaped sponge columns on the same side.

[0007] Preferably, a punching seat is fixedly provided at the top center of the base plate, and a vertically upward punching die is installed at the top center of the punching seat.

[0008] Preferably, a vertically upward support plate is fixedly provided on one outer wall of the base plate, a top plate is fixedly provided on one outer wall of the support plate, a fixing sleeve is fixedly provided on the bottom outer wall of the top plate through an opening, and a vertically downward electric push rod is fixedly provided on the inner wall of the fixing sleeve.

[0009] Preferably, the output end of the electric push rod is fixedly provided with an internally threaded fixing sleeve, the bottom of the internally threaded fixing sleeve is provided with a punch head, the top outer wall of the punch head is fixedly provided with a threaded post, and the inner wall of the internally threaded fixing sleeve is threadedly connected to the threaded post.

[0010] Preferably, the punching die is located directly below the punching head.

[0011] Preferably, the outer walls at both ends of the two positioning plates are provided with positioning holes, and the inner walls of the positioning holes are fixedly connected to the outer wall of the synchronous threaded rod through bearings.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] The two translation plates are adjusted by a synchronous threaded rod to move towards or away from each other. Together with the strip-shaped sponge column, the screen protector is clamped and positioned, ensuring that the screen protector is subjected to uniform force within the extrusion groove. This prevents tilting or twisting due to uneven local force, and also ensures that the screen protector remains horizontal during punching. The horizontally positioned punch head can act perpendicularly on the screen protector, increasing the accuracy of the punching position and avoiding punching offset caused by screen protector tilt, thus improving punching precision.

[0023] Example 1

[0024] Refer to the instruction manual appendix Figure 1-4A protective film perforation device for easy positioning includes a base plate 1. Two positioning plates 10 are fixedly installed on both sides of the top of the base plate 1. Two parallel translation plates 11 are arranged between the two positioning plates 10. The outer walls of both ends of the translation plates 11 are respectively provided with guide holes 12 and internal thread holes 13, and the guide holes 12 and internal thread holes 13 on the two translation plates 11 are in opposite positions. The outer walls of both ends of a synchronous threaded rod 15 are fixedly provided with knobs 16, and the two ends of the knobs are installed in the positioning holes 17 opened on the outer walls of the two positioning plates 10 through bearings, so that the synchronous threaded rod 15 can rotate stably. The outer wall of the synchronous threaded rod 15 is in clearance fit with the inner wall of the guide holes 12 on the two translation plates 11. Simultaneously, it is screwed to the inner wall of the internal threaded hole 13 on the two translation plates 11. When the knob 16 is turned to drive the synchronous threaded rod 15 to rotate, since the internal threaded holes 13 on the two translation plates 11 are in opposite positions, the two translation plates 11 will move in opposite directions or away from each other along the synchronous threaded rod 15. Two strip-shaped sponge pillars 14 are fixedly provided on the outer wall of the corresponding side of the two translation plates 11. An extrusion groove is formed between the strip-shaped sponge pillars 14 on the same side. When placing the protective film, the protective film can be placed in the extrusion groove. By adjusting the distance between the two translation plates 11, the strip-shaped sponge pillars 14 are used to clamp and position the protective film. The softness of the strip-shaped sponge pillars 14 can avoid damage to the protective film.

[0025] Example 2

[0026] Based on Embodiment 1, a punching seat 2 is fixedly provided at the top center of the base plate 1. A vertically upward punching die 3 is installed at the top center of the punching seat 2. The punching die 3 is used to cooperate with the punching head 9 to complete the punching operation. A vertically upward support plate 4 is fixedly provided on one side outer wall of the base plate 1. A top plate 5 is fixedly provided on one side outer wall of the support plate 4. A fixing sleeve 6 is fixedly provided on the bottom outer wall of the top plate 5 through an opening. A vertically downward electric push rod 7 is fixedly provided on the inner wall of the fixing sleeve 6. An internally threaded fixing sleeve 8 is fixedly provided at the output end of the electric push rod 7. A threaded column is fixedly provided on the top outer wall of the punching head 9. The inner wall of the internally threaded fixing sleeve 8 is threadedly connected to the threaded column. This threaded connection method facilitates the installation, disassembly and replacement of the punching head 9. The punching die 3 is located directly below the punching head 9. When the electric push rod 7 works, its output end drives the internally threaded fixing sleeve 8 and the punching head 9 to move downward. The punching head 9 cooperates with the punching die 3 to perform a punching operation on the protective film placed in the extrusion groove and positioned.

[0027] Working principle of this utility model:

[0028] Refer to the instruction manual appendix Figure 1-4When using this invention, the protective film to be punched is first placed stably between two translation plates 11 in the compression groove formed by the strip-shaped sponge pillars 14 on the same side. At this time, the protective film is roughly in the positioning area. The operator manually rotates the knobs 16 at both ends of the synchronous threaded rod 15. The knobs 16 drive the synchronous threaded rod 15 to rotate. Since the internal threaded holes 13 on the two translation plates 11 are in opposite positions, the two translation plates 11 will move towards each other along the synchronous threaded rod 15 during the rotation of the synchronous threaded rod 15. As the translation plates 11 approach each other, the strip-shaped sponge pillars 14 gradually apply clamping force to the protective film until the protective film is stably clamped and accurately positioned. The softness of the strip-shaped sponge pillars 14 can avoid damaging the protective film. After the protective film is positioned, the electric push rod 7 is activated. The output end of the electric push rod 7 extends downward, driving the internally threaded fixing sleeve 8 and the punching head 9 connected to the internally threaded fixing sleeve 8 via the threaded column to move downward together. The punching head 9 moves closer to the punching die 3 located directly below it. When the punching head 9 contacts the punching die 3 and applies sufficient pressure, the punching operation is completed on the protective film. After the punching is completed, the output end of the electric push rod 7 is controlled to retract upward, driving the punching head 9 to reset. Then, the knob 16 is rotated in the opposite direction, causing the synchronous threaded rod 15 to rotate in the opposite direction. The two translation plates 11 move in opposite directions, releasing the clamp on the protective film. The operator can then remove the punched protective film from the extrusion groove.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
