[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1-4 As shown, this embodiment proposes a solution: a membrane switch conductive silver paste printing template, including a mounting bracket 1, mounting seats 2 fixedly mounted on the front and rear sides of the mounting bracket 1, a sliding seat 3 sleeved on the surface of the mounting bracket 1 and slidably connected thereto, a lifting frame 4 fixedly mounted between two sliding seats 3 on the same side, a clamping frame 5 fixedly mounted on the side of the lifting frame 4 away from the mounting seat 2, a template body 6 placed on the inner side wall of the two clamping frames 5, a clamping component provided on the inner side of the lifting frame 4 for fixing and clamping the template body 6, and adjustment components provided on the left and right sides of the lifting frame 4 for adjusting according to the size of the template body 6.

[0021] In this implementation case, the mounting bracket 1 serves as the basic frame, and the mounting seats 2 on its front and rear sides are used for fixed connection with the printing device. The clamping frame 5 on the lifting frame 4 is used to initially place the template body 6. The clamping component can fix the template body 6 without manual adjustment, simplifying the operation steps, avoiding the need for special tools, improving the convenience of template assembly and disassembly, and thus improving the efficiency of the production line. The adjustment component can be adjusted according to the size of the template body 6, so that the device can adapt to templates of different specifications. Through the sliding of the sliding seat 3 and the cooperation of the adjustment component, the position of the lifting frame 4 can be flexibly adjusted, thus being compatible with template bodies 6 of different sizes. There is no need to replace the entire set of fixed brackets or purchase additional special positioning components, which improves the practicality of the device and its adaptability to various specifications.

[0022] The clamping assembly includes a lead screw 7, the top and bottom of which are rotatably connected to the inner wall of the adjacent lifting frame 4. A drive motor 8 is fixedly installed on the top of the lifting frame 4 to drive the lead screw 7 to rotate. A lifting plate 9 is threaded on the surface of the lead screw 7. A lifting groove is provided on the inner side of the lifting frame 4 for the lifting plate 9 to slide up and down. A connecting frame 10 is fixedly installed on the front side of the lifting plate 9. A lifting port is provided on the front side of the lifting frame 4 for the connecting frame 10 to slide up and down. A fixing component 11 is provided on the inner side of the connecting frame 10. Limiting components 12 are provided on the left and right sides of the lifting plate 9. The lead screw 7 rotates under the drive of the drive motor 8, causing the threaded lifting plate 9 to slide up and down along the lifting groove on the inner side of the lifting frame 4. The lifting plate 9 drives the connecting frame 10 to move up and down through the lifting port. The fixing component 11 on the connecting frame 10 can limit the top of the template body 6. At the same time, the limiting component 12 can limit the adjustment component, increasing the stability of the device. No manual adjustment is required, simplifying the operation steps, avoiding the need for special tools, improving the convenience of template assembly and disassembly, and thus improving the efficiency of the production line.

[0023] The fixing assembly 11 includes a fixing sleeve 1101. The connecting bracket 10 has an inner mounting hole adapted to the fixing sleeve 1101. The inner wall of the mounting hole is fixedly connected to the surface of the fixing sleeve 1101. A threaded rod 1102 is rotatably connected to the top inner side of the fixing sleeve 1101. A threaded sleeve 1103 is fitted onto the surface of the threaded rod 1102 and threadedly connected. The bottom end of the threaded sleeve 1103 penetrates the bottom inner side of the fixing sleeve 1101 and is fixedly mounted with a fixing block 1104. The top of the fixing sleeve 1101... A knob 1105 is rotatably connected to drive the threaded rod 1102 to rotate. The clamping frame 5 has a first connecting hole on its inner side for the fixed sleeve 1101 to pass through. Rotating the knob 1105 drives the threaded rod 1102 to rotate inside the fixed sleeve 1101, causing the threaded sleeve 1103 to move up and down, which in turn drives the fixed block 1104 to move up and down. Based on the thickness of the template body 6, the fixed block 1104 is adjusted to a suitable position, and in conjunction with the action of the drive motor 8, the template body 6 is limited.

[0024] The limiting component 12 includes a hinge rod 1201, which is rotatably connected to the surface of the lifting plate 9. A hinge block 1202 is rotatably connected to the other side of the hinge rod 1201. A moving groove is provided on the inner side of the lifting frame 4, allowing the hinge block 1202 to slide left and right. A limiting rod 1203 is fixedly installed on the side of the hinge block 1202 away from the lead screw 7. A second connecting hole is provided on the inner side of the lifting frame 4, allowing the limiting rod 1203 to pass through. The hinge rod 1201 rotates as the lifting plate 9 moves up and down, causing the hinge block 1202 to slide left and right in the moving groove on the inner side of the lifting frame 4, so that the limiting rod 1203 on the hinge block 1202 extends out through the second connecting hole, limiting the side of the adjusting component.

[0025] The adjustment assembly includes a first support block 13, whose sidewall is fixedly connected to the sidewall of the lifting frame 4. Two movable rods 14 are slidably connected to the inner side of the first support block 13. A second support block 15 is fixedly installed at the bottom of the two movable rods 14 on the same side. A positioning rod 16 is fixedly installed at the bottom of the second support block 15. A spring 17 is provided at the bottom of the first support block 13 and at the outer edge of the movable rods 14 to drive the second support block 15 to descend. The inner side of the mounting bracket 1 has multiple positioning holes. The inner side of the sliding seat 3 has a third connecting hole through which the positioning rod 16 can pass. A limit hole is provided on the side of the second support block 15 away from the mounting bracket 1. The sliding seat 3 is moved to a suitable position according to the size of the template body 6. The spring 17 pushes the second support block 15 to descend, so that the positioning rod 16 on the second support block 15 is inserted into the adjacent positioning hole on the inner side of the mounting bracket 1 through the third connecting hole on the inner side of the sliding seat 3, thereby fixing the position of the lifting frame 4. The limit hole can cooperate with the limit component 12 to increase the stability of the lifting frame 4.

[0026] The above embodiment discloses a conductive silver paste printing template for a membrane switch. The sliding seat 3 is moved to a suitable position according to the dimensions of the template body 6. A spring 17 pushes the second support block 15 downwards, causing the positioning rod 16 on the second support block 15 to insert through the third connecting hole on the inner side of the sliding seat 3 into the adjacent positioning hole on the inner side of the mounting bracket 1, thus fixing the position of the lifting frame 4. The lead screw 7 rotates under the drive of the drive motor 8, causing the lifting plate 9, with its surface threaded connection, to slide up and down along the lifting groove on the inner side of the lifting frame 4. The lifting plate 9 drives the connecting frame 10 to move up and down through the lifting port. The fixing component 11 on the connecting frame 10 can limit the top of the template body 6. Simultaneously, the limiting component 12 can limit the adjustment component, increasing the stability of the device. No manual adjustment is required, simplifying the operation. The steps avoid the need for special tools, improve the convenience of template assembly and disassembly, and thus improve production line efficiency. The rotation of knob 1105 drives threaded rod 1102 to rotate in fixed sleeve 1101, causing threaded sleeve 1103 to move up and down, which in turn drives fixed block 1104 to move up and down. Based on the thickness of template body 6, fixed block 1104 is adjusted to a suitable position. With the action of drive motor 8, template body 6 is limited. At the same time, hinge rod 1201 rotates with the up and down movement of lifting plate 9, causing hinge block 1202 to slide left and right in the moving groove inside lifting frame 4. The limiting rod 1203 on hinge block 1202 extends out through the second connecting hole and is inserted into the limiting hole opened in the second support block 15, increasing the stability of lifting frame 4.
