[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figure 1 、 Figure 3 and Figure 4 , an embodiment provided by the present utility model: an adjustable double-sided knurling loosening device and a double-sided film tearing machine having the same, including a vertical shell 1. Fixing plates 3 are arranged at both the upper and lower ends of the front side of the vertical shell 1. Two bolts 4 are threadedly connected to the right end of the front side of the fixing plate 3, and the rear ends of the bolts 4 are threadedly connected to the front side of the vertical shell 1. A cylinder 5 is fixedly connected to the left side of the fixing plate 3. One end of the cylinder 5 is fixedly connected to a displacement plate 6. Connecting plates 7 are fixedly connected to both the front and rear ends of the right side of the displacement plate 6. A fixing column 8 is fixedly connected to one side of the connecting plate 7. Fixing columns 8 are fixedly connected to both the front and rear ends of one side of the fixing column 8. A film tearing plate 9 is fixedly connected to one side of the displacement plate 6. A driving mechanism 2 is arranged on the right side of the inner wall of the vertical shell 1. The driving mechanism 2 is used to improve the automation of the device, thereby facilitating the automatic film tearing work of the circuit board.

[0033] Specifically, by starting the two cylinders 5, their one ends can drive the displacement plate 6 to move up and down, so as to adjust the distance between the two displacement plates 6, meeting the requirement of adapting to circuit boards of different specifications for film tearing work. When the circuit board is placed in an appropriate position, through the drive of the cylinder 5, the displacement plate 6 will adjust the spacing accordingly to ensure that it can adapt to the size of the circuit board. Through the two cutting members 10 fixed to one side of the fixing column 8, the protective films on the upper and lower sides of the circuit board can be precisely cut, thereby cutting open the protective films. When the protective films are cut open, the film tearing plate 9 can engage with the broken protective films. When the circuit board moves, the film tearing plate 9 can tear off the protective films, not only avoiding the possibility of reducing the processing range during the film tearing process, but also greatly improving the flexibility of the device and the convenience of operation.

[0034] Referring to Figure 2 、 Figure 3 and Figure 5, the driving mechanism 2 includes a fixed housing 201. The right side of the fixed housing 201 is fixedly connected to the right inner wall of the vertical housing 1. The inner bottom wall of the fixed housing 201 is fixedly connected with a tooth seat 202. The front side of the fixed housing 201 is provided with a fixed block 203. The front side of the fixed block 203 is fixedly connected with a pneumatic gripper 204. The left and right ends of the front side of the pneumatic gripper 204 are both fixedly connected with rubber pads 205. The rear side of the fixed block 203 is fixedly connected with a servo motor 206. The output end of the servo motor 206 is fixedly connected with a gear 207. The gear 207 is meshed with the tooth seat 202. A chute 208 is opened on the front side of the fixed housing 201. The outer wall of the fixed block 203 is slidably connected with the chute 208;

[0035] Specifically, by starting the servo motor 206, the driving gear 207 connected thereto is driven to rotate. Its teeth are meshed with the tooth grooves on the tooth seat 202, driving the fixed block 203 to slide in the chute 208, enabling the fixed block 203 to displace along a specific axis. The combined use of the pneumatic gripper 204 and the rubber pads 205 can clamp or loosen the circuit board, and the rubber pads 205 provide necessary buffering and protection to prevent damage to the circuit board during the clamping process. Thus, when the fixed block 203 displaces, the circuit board can displace together with the fixed block 203, ensuring the stability during film tearing, making the film tearing process of the circuit board more efficient and smooth, and improving the overall efficiency of the film tearing work.

[0036] Refer to Figure 1 、 Figure 4 and Figure 5 , the top wall of the fixed block 203 is fixedly connected with a stabilizing plate 17. A limiting groove 18 is opened on the top wall of the fixed housing 201. The rear side of the bottom of the stabilizing plate 17 is slidably connected with the limiting groove 18; The right end of the front side of the vertical housing 1 is fixedly connected with a control switch 13. The control switch 13 is electrically connected to the cylinder 5 and the servo motor 206 respectively; The front and rear sides of the two displacement plates 6 are both fixedly connected with support plates 11. Rollers 12 are rotatably connected inside multiple support plates 11;

[0037] Specifically, by the rear side of the bottom of the stabilizing plate 17 being slidably connected with the limiting groove 18, the stability of the displacement of the fixed block 203 is improved. By the control switch 13 electrically connected to the cylinder 5 and the servo motor 206 respectively, the control switch 13 can turn on and off the device. By the support plates 11 and the rollers 12, it is convenient to assist the circuit board in tearing the film smoothly.

[0038] Refer to Figure 1 and Figure 4, two connecting seats 14 are fixedly connected to both the left and right sides of the vertical case 1, and mounting grooves 15 are provided on the front sides of the plurality of connecting seats 14; inclined surfaces are provided in the middle of the front side of the vertical case 1, and both inclined surfaces are symmetrically designed; rubber rings 16 are fixedly connected to the middle parts of the plurality of bolts 4, and the plurality of bolts 4 are arranged at equal intervals;

[0039] Specifically, the connection between the connecting seat 14 and the mounting groove 15 facilitates the fixed installation of the device. The inclined surfaces provided in the middle of the front side of the vertical case 1 reduce the possibility of contact between the circuit board and the vertical case 1. The rubber ring 16 reduces the rotational damage of the bolt 4 to the fixing plate 3.

[0040] Working principle: Before use, by starting the two cylinders 5, one end of which can drive the displacement plate 6 to move up and down, so as to adjust the distance between the two displacement plates 6, thus completing the preparation for the film tearing work according to circuit boards of different specifications. Then, under the displacement of the circuit board, the two cutting members 10 can cut the protective film on the upper and lower sides of the circuit board. At the same time, the two film tearing plates 9 fixed on one side of the fixed column 8 can engage with the broken protective film, and then can cover the protective film. Thus, under the displacement of the circuit board, the film tearing plate 9 can tear off the protective film, avoiding the possible reduction of the processing range during the film tearing of the circuit board, thereby improving the flexibility of the device;

[0041] And by starting the servo motor 206, it drives the gear 207 to rotate. Thus, the gear 207 rotates on the tooth seat 202, causing the gear 207 to drive the fixed block 203 to slide in the chute 208, enabling the fixed block 203 to perform axial displacement. At the same time, the pneumatic gripper 204 and the rubber pad 205 can clamp and fix the circuit board, so that the circuit board moves together with the fixed block 203, thereby improving the automation during the operation of the film tearing device and enhancing the working efficiency of the film tearing of the circuit board.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
