Abstract

This utility model provides a quick-change mold structure for a circuit board pressing machine, belonging to the field of circuit board processing technology. It includes a processing table with a functional mechanism on its upper surface. The functional mechanism includes a placement seat mounted on the surface of the processing table. A sliding groove is formed on the surface of the placement seat, and two movable platforms are slidably connected to the surface of the sliding groove. A threaded rod is rotatably connected inside the placement seat. This solution uses the rotation of the threaded rod to move the clamping plate, thereby adjusting it according to the mold size. The rotation of the threaded rod also moves the movable platforms. At this time, under the action of the transmission gear plate and transmission gear, the connecting seat rotates. The rotation of the connecting seat, under the action of the arc-shaped connecting piece, causes the movable platform to move on the surface of the second guide rod. The movement of the movable platform can drive the clamping plate to move, thereby achieving mold limiting and release, and thus realizing the effect of quick mold switching.

[0002] A circuit board, also known as a printed circuit board, is composed of integrated circuits, quartz oscillators, trimmer capacitors, and the printed circuit board itself. Circuit boards are also called ceramic circuit boards, alumina ceramic circuit boards, and aluminum nitride ceramic circuit boards. Circuit boards miniaturize and visualize circuits, playing a crucial role in the mass production of fixed circuits and the optimization of electrical appliance layout.

[0003] Existing molds require repeated disassembly, handling, and fixing during switching, which is time-consuming and labor-intensive, affecting the production rhythm. Furthermore, the single mold structure cannot be compatible with circuit boards of different sizes, requiring frequent replacement of the entire mold and increasing costs. Therefore, we propose a rapid mold switching structure for circuit board laminating machines. Utility Model Content

A threaded rod 204 is rotatably connected inside the placement seat 201, and the threaded rod 204 is threaded to the surface of the movable table 203. Transmission gear plates 208 are fixedly connected to both sides of the upper surface of the placement seat 201. Transmission gears 209, adapted to the transmission gear plates 208, are rotatably connected inside the movable table 203. A connecting seat 212 is fixedly connected to the surface of the transmission gear 209. Two arc-shaped connecting pieces 213 are rotatably connected to the surface of the connecting seat 212. A second guide rod 210 is installed inside the movable table 203. Two movable seats 211 are slidably connected to the surface of the second guide rod 210, and the two movable seats 211 are slidably connected to the surface of the second guide rod 210. The movable seat 211 is rotatably connected to the surfaces of two arc-shaped connecting parts 213. A threaded screw rod 214 is threadedly connected to the surface of the movable seat 211. A clamping plate 215 is fixedly connected to the inner side of the threaded screw rod 214. The rotation of the threaded screw rod 214 drives the clamping plate 215 to move, thereby adjusting according to the size of the mold. The rotation of the threaded rod 204 drives the movable stage 203 to move. At this time, the connecting seat 212 is rotated under the action of the transmission gear plate 208 and the transmission gear 209. The rotation of the connecting seat 212 causes the movable seat 211 to move on the surface of the second guide rod 210 under the action of the arc-shaped connecting parts 213. The movement of the movable seat 211 can drive the clamping plate 215 to move, thereby realizing the limiting and release of the mold, and thus achieving the effect of rapid mold switching.

[0028] Specifically, a servo motor 207 is mounted on the surface of the placement base 201, and the output shaft of the servo motor 207 is fixedly connected to one end of the threaded rod 204.

[0029] In a specific embodiment of this utility model, the output shaft of the servo motor 207 is started to drive the threaded rod 204 to rotate, and the rotation of the threaded rod 204 drives the moving table 203 to move.

[0030] Specifically, a first guide rod 205 is installed inside the placement seat 201 and on both sides of the threaded rod 204. A first sliding block 206 is fixedly connected to both sides of the moving table 203, and the first sliding block 206 is slidably connected to the surface of the first guide rod 205.

[0031] In a specific embodiment of this utility model, when the moving platform 203 moves, it drives the first sliding block 206 to move on the surface of the first guide rod 205, thereby increasing the stability of the moving platform 203 during movement.

[0032] Specifically, two spring telescopic rods 216 are fixedly connected to the inner surface of the clamping plate 215, and a buffer plate 217 is fixedly connected to the inner side of the spring telescopic rods 216.

[0033] In a specific embodiment of this utility model, by using the spring telescopic rod 216 and the buffer plate 217 together, when the clamping plate 215 moves, it drives the spring telescopic rod 216 and the buffer plate 217 to move inward, thereby clamping the mold and improving the stability of clamping the mold.

[0034] Specifically, an adjustment knob 218 is fixedly connected to one end of the outer side of the clamping plate 215, and the surface of the adjustment knob 218 is covered with an anti-slip sleeve.

[0035] In a specific embodiment of this utility model, the setting of the adjustment knob 218 facilitates the rotation of the threaded rod 214 by the operator, and the setting of the anti-slip sleeve increases the friction force when the operator rotates the adjustment knob 218.

[0036] Specifically, two limiting rods 219 are fixedly connected to the surface of the clamping plate 215, and two sliding sleeves 220 are installed on the surface of the moving seat 211, with the limiting rods 219 slidably connected to the inside of the sliding sleeves 220.

[0037] In a specific embodiment of this utility model, when the clamping plate 215 moves, it will drive the limiting rod 219 to move inside the sliding sleeve 220, thereby increasing the stability of the clamping plate 215 when it moves.

[0038] Specifically, the surface of the processing table 1 is rotatably connected to two protective doors 3, and the surface of the protective doors 3 is fixedly connected to a movable handle 4.

[0039] In a specific embodiment of this utility model, the protective door 3 can protect the items stored inside the processing table 1, and the movable handle 4 facilitates the opening and closing of the protective door 3.

[0040] Working principle: The rotation of the threaded rod 214 drives the clamping plate 215 to move, thereby adjusting according to the size of the mold. When mold switching is required, the servo motor 207 is activated. The output shaft of the servo motor 207 drives the threaded rod 204 to rotate. The rotation of the threaded rod 204 drives the moving table 203 to move. At this time, under the action of the transmission gear plate 208 and the transmission gear 209, the connecting seat 212 rotates. Under the action of the arc-shaped connecting piece 213, the moving seat 211 moves on the surface of the second guide rod 210. The movement of the moving seat 211 can drive the clamping plate 215 to move. When the clamping plate 215 moves, it drives the spring telescopic rod 216 and the buffer plate 217 to move inward, thereby limiting and releasing the mold, and thus achieving the effect of rapid mold switching.
