[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0020] Please refer to 1-2, a device for punching holes in a protective film of an electronic product, comprising a workbench 1, an L-shaped support frame 3 is fixedly connected to the top of the workbench 1, a rotating shaft 7 is rotatably arranged on the L-shaped support frame 3, a spiral groove 71 connected end to end is opened on the rotating shaft 7, a slide bar 8 is slidably arranged in the spiral groove 71 connected end to end, a slider 81 is fixedly connected to the slide bar 8, a punching head 9 is fixedly connected to the bottom end of the slider 81, a rectangular limit block 31 for limiting the left and right movement of the slide bar 8 is arranged on the L-shaped support frame 3, a half-shaped gear 10 is fixedly sleeved on the bottom end of the rotating shaft 7, a rack plate 6 is slidably arranged on the workbench 1, and the rack plate 6 is meshed with the half-shaped gear 10.

[0021] Specifically, refer to Figure 1 and Figure 2 In the utility model, under the limiting action of the rectangular limiting block 31, the rotating shaft 7 drives the sliding rod 8 to reciprocate in the vertical direction, so that the punching head 9 can punch holes in the protective film. When the rotating shaft 7 rotates, it drives the half-shaped gear 10 to rotate. Driven by the half-shaped gear 10, the rack plate 6 slides intermittently on the workbench 1 to punch holes in the protective film arranged on the rack plate 6 in sequence, realizing the production of protective film punching line, greatly improving the efficiency of protective film punching, and avoiding the potential risks of the punching head 9 to the staff.

[0022] Furthermore, a slide groove 11 is provided on the workbench 1 , and a plurality of rollers 2 are rotatably arranged in the slide groove 11 . The rack plate 6 is slidably arranged in the slide groove 11 , and the rack plate 6 is located on the plurality of rollers 2 .

[0023] Specifically, refer to Figure 1 By setting a plurality of rollers 2, the friction force between the rack plate 6 and the roller 2 is converted into rolling friction, thereby improving the power conversion rate of the driving source. By sliding the rack plate 6 in the slide groove 11, the sliding direction of the rack plate 6 is limited, thereby ensuring that the quality of the protective film obtained by punching holes in batches by the punching head 9 is consistent.

[0024] Furthermore, the top end of the rectangular limit block 31 is fixedly connected to the L-shaped support frame 3 , a limit slot 311 is provided on the rectangular limit block 31 , the slide bar 8 reciprocates in the limit slot 311 , and the slide block 81 is slidably arranged on the rectangular limit block 31 .

[0025] Specifically, refer to Figure 1 and Figure 2 There are two ways to connect the slider 81. First, a sliding groove for the slider 81 to slide is provided on the rectangular limit block 31, and when the rotating shaft 7 rotates, the slider 81 is driven to reciprocate in the vertical direction; second, the slider 81 is directly movably sleeved on the outside of the rectangular limit block 31, one end of the slide rod 8 is fixedly connected to the slider 81, and the other end is slidably set in the spiral groove 71 connected end to end. By rotating the rotating shaft 7, the slider 81 is made to reciprocate outside the rectangular limit block 31, and then the punching head 9 is driven to punch holes in the protective film.

[0026] Furthermore, a motor 4 and a reducer 5 are fixedly mounted on the top of the L-shaped support frame 3, and the reducer 5 drives the rotating shaft 7 to rotate.

[0027] Specifically, refer to Figure 1 The speed of the motor 4 is adjusted by the reducer 5, and a suitable speed ratio is set for driving. At the same time, by setting a plurality of rollers 2, the collision force of the meshing teeth between the half-shaped gear 10 and the rack plate 6 is reduced as much as possible, thereby extending the service life of the half-shaped gear 10.

[0028] Furthermore, a positioning block 12 is fixedly connected to the top of the workbench 1 , and the positioning block 12 is located beside the slide slot 11 .

[0029] Specifically, by providing the positioning block 12 , when the staff puts the rack plate 6 into the slide groove 11 , they put the end of the rack plate 6 close to one side of the positioning block 12 , so that the rack plate 6 is just meshed with the half gear 10 .

[0030] Furthermore, a plurality of film grooves 61 are formed on the rack plate 6 .

[0031] Specifically, the number of film grooves 61 opened depends on the length of the rack plate 6. In order to facilitate the transportation and pushing of the rack plate 6, the length of the rack plate 6 is often set to accommodate 20 protective films. The interval between the two film grooves 61 depends on the stroke length of the half-gear 10 pushing the rack plate 6 each time.

[0032] In this utility model, reference is made to Figure 1 and Figure 2 First, fill the protective film into the film groove 61 opened on the rack plate 6, then put the head of the rack plate 6 close to the positioning block 12, and then push the rack plate 6 into the slide groove 11, so that the rack plate 6 is engaged with the half-shaped gear 10, start the motor 4, so that the rotating shaft 7 rotates, and then drives the punching head 9 to reciprocate in the vertical direction. When the punching head 9 moves upward, the half-shaped gear 10 pushes the rack plate 6 to move, so that the next unpunched protective film moves to the bottom of the punching head 9, and the next round of punching is carried out.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that 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.
