Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production, and in particular to a pressing device for producing ceramic circuit boards. Background Art

[0002] Ceramic circuit boards (PCBs) are electronic circuit boards that use ceramic materials as their substrates. Compared to traditional PCBs made of organic materials like FR-4 epoxy fiberglass, ceramic PCBs offer higher heat resistance, better chemical stability, and superior mechanical properties. These characteristics make ceramic PCBs widely used in high-temperature, high-pressure, and corrosive environments.

[0003] During the manufacturing process, ceramic substrates often need to be bonded to metal or other materials, a process called "lamination." Adhesives or other substances may be used during lamination. If these substances are not fully cured or removed, they may cause adhesion between the ceramic circuit board and the lamination tools (such as the die, workbench, etc.), or cause the circuit board to fit too tightly to the tool. This not only affects subsequent removal operations but can also make removal difficult.

[0004] Therefore, in view of the above problems, there is an urgent need to develop a pressing device for ceramic circuit board production that is easy to remove components to ensure the smooth progress of the production process. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned prior art, the utility model provides a pressing device for ceramic circuit board production that is easy to remove components, so as to ensure the smooth progress of the production process.

A second elastic member is provided between the contact rod and the guide rod.

[0007] As an improvement to the above scheme, it also includes a mounting seat, a first slide bar and a limit plate. A mounting seat is provided at each of the four corners of the placement table. A first slide bar is slidingly provided on the mounting seat. A limit plate is provided between the upper and lower ends of the first slide bar and is passed through the mounting seat to limit the position of the circuit board.

[0008] As an improvement to the above solution, a first elastic member is further included. The first elastic member, which is sleeved on the first sliding rod, is provided between the limiting plate and the mounting seat on the same side.

[0009] As an improvement to the above solution, a material preparation plate is further included, and a material preparation plate is rotatably arranged on both sides of the bottom plate.

[0010] As an improvement to the above solution, a return spring is further included, and a return spring is arranged between the second sliding rod and the placement platform.

[0011] As an improvement to the above solution, the bottom end of the contact rod has an inclined surface that is symmetrical in the upper and lower directions, which is suitable for fitting with the protruding rod to push the lifting plate to move.

A second slide bar 10 is respectively penetrated and slidably provided at the four sides of the top surface of the placing table 2. A lifting plate 11 is provided between the top ends of the four second slide bars 10. The lifting plate 11 is also used for placing the circuit board, and the sliding operation of the second slide bar 10 is utilized to make the lifting plate 1 The lifting plate 11 is provided with a protruding rod 12 on both sides of the front and rear sides of the lifting plate 11, and a guide rod 13 is provided on the lower pressing plate 5 to match the layout of the protruding rod 12. A contact rod 14 is slidably provided on the guide rod 13 to contact and cooperate with the protruding rod 12 on the same side. The contact rod 14 slides left and right. The bottom end of the contact rod 14 has an upper and lower symmetrical inclined surface. The inclined surface has a small inclination, which enables it to be suitable for the moving rod of the lower pressing plate 5 to achieve adaptive contact and cooperation, so that the protruding rod 12 is fitted to push the lifting plate 11 to move, thereby generating a gap between the lifting plate 11 and the placing table 2, providing space for taking, and making it more convenient to take the circuit board. A second elastic member 15 is provided between the contact rod 14 and the guide rod 13. In this embodiment, the second elastic member 15 is an elastic member that can provide elastic support for the operation of the contact rod 14, so that the contact rod 14 can be reset.

[0021] like Figure 3As shown, it also includes a mounting seat 6, a first slide bar 7 and a limit plate 8. A mounting seat 6 is provided on each of the four corners of the placement table 2. The mounting seat 6 is in the shape of a right-angle plate, and a first slide bar 7 is slidingly provided on the mounting seat 6. A limit plate 8 is provided between the upper and lower ends of the first slide bar 7 and is passed through the mounting seat 6 to limit the position of the circuit board, thereby limiting the four corners of the circuit board respectively, making the placement of the circuit board more stable, so as to improve the accuracy of the pressing operation.

[0022] like Figure 3 As shown, a first elastic member 9 is also included. A first elastic member 9 is provided between the limiting plate 8 and the mounting seat 6 on the same side and is sleeved on the first slide rod 7. In this embodiment, the first elastic member 9 is a spring, which can provide the elastic support required for the reset operation of the mounting seat 6.

[0023] like Figure 2 As shown, a material preparation plate 16 is also included. A material preparation plate 16 is rotatably provided on both sides of the base plate 1. The material preparation plate 16 can be rotated and laid down to place subsequent materials to be used thereon, thereby improving the convenience of operation.

[0024] like Figure 4 As shown, a return spring 17 is also included, and a return spring 17 is provided between the second slide bar 10 and the placement platform 2.

[0025] When it is necessary to use this device, first place the device on a stable work surface, then place the circuit board that needs to be pressed on the lifting plate 11, and then place the metal plate or circuit board that needs to be used later directly on the preparation plates 16 on both sides, then calibrate the position between the circuit board and the four limit plates 8, so that the four corners of the circuit board can be limited between the limit plates 8, and then start the cylinder 4, which drives the lower pressing plate 5 to press down and fit the circuit board, thereby performing the pressing operation. From then on, the lower pressing plate 5 will fit with the limit plates 8 on all sides, and push the limit plates 8 to slide down on the mounting seat 6, and the connected first slide bar 7 will also The first elastic member 9 is also deformed by force, so that the limit plate 8 can fit the operation of the lower pressing plate 5 to control the distance between the circuit board and the lower pressing plate 5. At the same time, due to the downward movement of the lower pressing plate 5, the contact rod 14 thereon moves downward synchronously, and the contact rod 14 gradually approaches the convex rod 12 on the same side and contacts it, so that the lower end inclined surface of the contact rod 14 contacts the convex rod 12. Subsequently, affected by the inclined surface, the contact rod 14 is pushed to move to the left, causing it to slide to the left on the guide rod 13, and the second elastic member 15 is deformed accordingly. After the contact rod 14 moves to a certain distance, it will break away from the contact with the convex rod 12, and the second elastic member 15 moves along The contact rod 14 is reset, and the contact rod 14 is also moved and reset to the right side of the guide rod 13, and the bottom end of the contact rod 14 is hooked under the convex rod 12. After the pressing operation of the circuit board is completed, that is, the lower pressing plate 5 needs to move up, and drive the contact rod 14 to operate synchronously, through the upper end inclined surface of the contact rod 14 to contact the convex rod 12. Because the inclination angle of the upper end inclined surface is small, it is not easy to make the inclined surface match, and then the contact rod 14 will be against the bottom of the convex rod 12, pulling and driving the convex rod 12 together with the lifting plate 11 to move up, the second slide bar 10 moves on the placement table 2, and the reset spring 17 is deformed accordingly. After the slide bar 10 moves to the end, there is a gap between the lifting plate 11 and the placement table 2, leaving space for taking the circuit board, making it more convenient to take the circuit board, and then the circuit board that needs to be taken can be taken out; from then on, since the second slide bar 10 has moved to the end, the contact rod 14 will use its inclined surface to cooperate with the protruding rod 12, and the contact rod 14 will move to the left under the influence of the inclined surface, and then break away from the contact with the protruding rod 12. From then on, the lifting plate 11 is freed from the restriction and moves downward under the force of the reset spring 17, and then the device returns to its original state, and the above operation can be repeated to perform batch circuit board pressing operations.
