Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1, referring to Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a positioning and cutting device for adhesive film slitting, which can improve the positioning accuracy of adhesive film slitting, reduce the curling phenomenon of the cutting edge, and ensure the flatness of the edge of the adhesive film after slitting. It includes a cutting mechanism, which includes two rollers 10. A base 11 is fixedly arranged between the rollers 10. Two side plates 12 are fixedly arranged in the middle of the upper end of the base 11. An arch bridge groove 13 is opened in the middle of the side plate 12. Several T-shaped pressure plates 14 are movably arranged through the lower end of the inner cavity of the arch bridge groove 13. Adhesive film 15 is abutted at the lower end of the T-shaped pressure plate 14. A moving component 16 for reciprocating cutting is arranged at the upper end of the two adhesive films 15.

[0027] The moving component 16 includes a servo motor 161 fixedly mounted at one end of the base 11 for power transmission. A threaded rod 162 is fixedly mounted at the output end of the servo motor 161. A moving seat 163 is provided through the external thread of the threaded rod 162. A cutter 164 for cutting the adhesive film 15 is fixedly mounted at the lower end of the moving seat 163.

[0028] A central shaft 165 is fixedly installed on both sides of the movable seat 163. Two connecting rods 166 are rotatably installed at the end of the central shaft 165 away from the movable seat 163. A guide column 167 that can move inside the arch bridge groove 13 is rotatably installed at the end of the connecting rod 166 away from the central shaft 165. Two balance bars 168 with the same structure are movably installed through the upper end of the movable seat 163 and arranged in an array. The balance bars 168 are used to maintain the stability of the movable seat 163 and to guide it.

[0029] Specifically, during the movement of the movable seat 163, the central shaft 165, the connecting rod 166, and the guide column 167 cooperate with each other. The guide column 167 moves within the arch bridge groove 13. The connecting rod 166 and the central shaft 165 guide and restrict the movement direction of the movable seat 163. At the same time, the balance bar 168 further ensures the stability of the movement of the movable seat 163 and prevents the cutter 164 from shaking.

[0030] Furthermore, several first compression springs 17 are fixedly installed on both sides of the lower end of several T-shaped pressure plates 14 and are fixedly connected to the lower end surfaces of both sides of the side plate 12. The first compression springs 17 are used to reset the T-shaped pressure plates 14.

[0031] Among them, the servo motor 161 can be a servo motor of model SGMAH-01AAA41. This model of motor has high-precision speed control and position positioning capabilities, and can accurately drive the threaded rod 162 to rotate, thereby ensuring that the moving seat 163 and the cutter 164 move according to the preset trajectory and speed, further improving the positioning accuracy of cutting.

[0032] In use, the roller 10 is first used to convey the adhesive film 15 so that it can be continuously conveyed to the bottom of the T-shaped pressure plate 14. Then, the servo motor 161 is started, and the servo motor 161 drives the threaded rod 162 to rotate. Since the threaded rod 162 is threadedly connected to the moving seat 163, the rotation of the threaded rod 162 is converted into the linear movement of the moving seat 163, so that the cutter 164 can start to move towards the surface of the adhesive film 15.

[0033] The guide posts 167, which are respectively set on the two connecting rods 166, can pass through several protruding arch-shaped upward grooves set on the arch bridge groove 13. The upward grooves of this structure are set at the joint position of the two T-shaped pressure plates 14. When the front guide post 167 passes through the upward groove, it can squeeze the T-shaped pressure plate 14, which is pulled by the first compression spring 17 to press down the adhesive film 15, and press the adhesive film 15. Then, as the moving seat 163 moves, the rear guide post 167 passes through the upward groove in the upper arch bridge groove 13 and releases the front T-shaped pressure plate 14, so that it no longer presses down on the adhesive film 15. As a result, when the cutter 164 cuts the adhesive film 15, the T-shaped pressure plate 14 can press down on the adhesive film 15 in advance, so that the cutter 164 can cut the adhesive film 15 better.

[0034] Example 2, refer to Figures 5-6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a top pressing mechanism for a positioning and cutting device for adhesive film slitting, which solves the problems of wrinkle generation, edge curling, and poor cutting stability during the cutting process. It includes a top pressing mechanism, which includes a trapezoidal pressure plate 20 fixedly disposed at the lower end of the opposite side of the T-shaped pressure plate 14. Two positive trapezoidal plates 21 are disposed between the trapezoidal pressure plates 20. A V-shaped groove 22 for reducing edge curling during cutting is opened on the upper end of the abutting surface of the positive trapezoidal plates 21. Both ends of the positive trapezoidal plates 21 are provided with lifting components 23 for lifting and pressing the adhesive film 15.

[0035] The lifting assembly 23 includes a lower groove 231 located in the middle of the lower end of the base 11. Both ends of the inner cavity of the lower groove 231 are slidably provided with inverted trapezoidal plates 232 for pushing the positive trapezoidal plate 21 up and down. Several second compression springs 233 are fixedly provided on the bottom surface of the inner cavity of the lower groove 231 for resetting the positive trapezoidal plate 21 and the inverted trapezoidal plate 232. A Z-shaped pressure groove 234 is provided at the junction of the inverted trapezoidal plate 232, the positive trapezoidal plate 21, and the trapezoidal pressure plate 20 for bending and squeezing the adhesive film 15 to achieve further tension.

[0036] Specifically, the inclined surface of the inverted trapezoidal plate 232 matches the inclined surface of the regular trapezoidal plate 21. When the inverted trapezoidal plate 232 moves horizontally, it will push the regular trapezoidal plate 21 to rise and fall vertically through the interaction of the inclined surfaces. The shape of the Z-shaped pressure groove 234 is adapted to the junction of the trapezoidal pressure plate 20, the regular trapezoidal plate 21, and the inverted trapezoidal plate 232. When the regular trapezoidal plate 21 is lifted, the Z-shaped pressure groove 234 can form multi-segment bending and extrusion on the adhesive film 15, so that the film is subjected to tension from different directions near the cutting area, thereby adhering more tightly to the cutting position and avoiding wrinkles.

[0037] In use, when the servo motor 161 drives the threaded rod 162 to move the moving seat 163 and the cutter 164 to cut, the inverted trapezoidal plate 232 is pushed down by the guide post 167 to move the T-shaped pressure plate downward, and then the inverted trapezoidal plate 232 moves downward along the lower groove 231. At the same time, its inclined surface pushes the upright trapezoidal plate 21 upward. During the upward process, the upright trapezoidal plate 21 cooperates with the trapezoidal pressure plate 20 and bends and squeezes the adhesive film 15 through the Z-shaped pressure groove 234. The bending range is between 2mm and 5mm, so that the adhesive film 15 is kept taut at the cutting part.

[0038] Meanwhile, the V-groove 22 on the trapezoidal plate 21 corresponds to the movement trajectory of the cutter 164. When the cutter 164 is driven by the moving component 16 to cut, the blade of the cutter 164 can extend into the V-groove 22, effectively reducing the curling of the cutting edge. At the same time, the height of the V-groove 22 is between 1mm and 3mm, so as to reduce the curling of the cutting edge and avoid excessive stretching of the adhesive film 15.

[0039] After cutting, the inverted trapezoidal plate 232 is reset under the counter-pushing action of the second compression spring 233, and the upright trapezoidal plate 21 is pulled down by the second compression spring 233 to release the lifting and pressing of the film so as to carry out the next cutting operation.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
