DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] The following describes an embodiment of the present invention based on its overall structure.

[0025] A circuit board pressing fixture, such as Figure 1-4 As shown, it includes a base plate 1, and a first positioning block 2 and a second positioning block 3 are provided on the top of the base plate 1, wherein the first positioning block 2 extends into the interior of the base plate 1 and is connected to the base plate 1 through a spring sliding reset connection, while the second positioning block 3 is connected to the end surface of the base plate 1 through a spring sliding reset connection;

[0026] Furthermore, in this embodiment, a top plate 4 is provided above the bottom plate 1, and a dust box 5 slidably connected to the top plate 4 is installed at the bottom end of the top plate 4. The interior of the dust box 5 contains a fan, and the top end of the dust box 5 is connected to a telescopic tube 7, and one side of the telescopic tube 7 is located inside the top plate 4 and an exhaust pipe 6 extending to the outside of the top plate 4 is installed, and the telescopic tube 7 is connected to the exhaust pipe 6.

[0027] See also Figure 1-2 The outer wall of the dust collection box 5 is fixedly connected with a synchronization rod 8, and the end of the synchronization rod 8 is arranged on the outside of the second positioning block 3 to realize the driving of the second positioning block 3.

[0028] See also Figure 3 An electric guide rail 9 is installed inside the top plate 4, and a slider 10 adapted to the electric guide rail 9 is installed on the outer wall of the electric guide rail 9. The slider 10 is fixed to the top of the dust box 5 and is slidably connected to the inner wall of the top plate 4 to drive the dust box 5.

[0029] See also Figure 3-4A driven gear 11 is installed on the side wall of the top plate 4, and the top of the driven gear 11 is meshed with a driving gear plate 12, and the driving gear plate 12 is synchronously connected to the outer wall of the slider 10, and the outer side of the driven gear 11 is connected to the power box 13, and the power box 13 contains two sets of turntables and belts sleeved on the outer walls of the two sets of turntables. The driven gear 11 is connected to one set of turntables in the power box 13 through a one-way bearing transmission, and the other set of turntables in the power box 13 is synchronously connected with a telescopic shaft 14 extending to the outside of the first positioning block 2, and a threaded rod 15 extending to the inside of the bottom plate 1 is connected between the telescopic shaft 14 and the outer wall of the first positioning block 2, and a threaded wall adapted to the threaded rod 15 is provided on the inner wall of the bottom plate 1, and the threaded rod 15 is rotatably connected to the outer wall of the first positioning block 2 through a bearing, and the threaded rod 15 is also connected to the outer wall of the power box 13 through a telescopic torsion spring shaft to realize the driving of the first positioning block 2.

[0030] The working principle of the present invention is as follows: first, the inner plate is placed on the bottom plate 1, and then the pressing material can be placed on the inner plate, and the electric guide rail 9 and the fan in the dust box 5 are started. At this time, the electric guide rail 9 drives the slider 10 to move on its outer wall, and the movement of the slider 10 drives the dust box 5 to move, so that the dust box 5 can perform a full range of dust collection on the pressing material, thereby improving the quality of the pressing material, that is, improving the pressing quality of the inner plate;

[0031] Furthermore, as the slider 10 moves, it drives the driving gear plate 12 to move, and the driving gear plate 12 in turn drives the driven gear 11 to rotate. After the driven gear 11 rotates, it transmits power to the telescopic shaft 14 through the power box 13. The telescopic shaft 14 in turn drives the threaded rod 15 to rotate. After the threaded rod 15 rotates, it moves inward under the action of the threaded wall of the inner wall of the bottom plate 1, thereby pushing the first positioning block 2 to move, thereby achieving positioning of both sides of the laminated material.

[0032] In addition, after the tooth wall of the driving tooth plate 12 moves to a point where it is no longer in contact with the driven gear 11, the telescopic shaft 14 will reset and rotate under the action of the torsion spring shaft, so the threaded rod 15 will also reset and rotate, causing the thrust on the first positioning block 2 to disappear. At this time, the first positioning block 2 will reset to its initial state. At the same time, the end of the synchronization rod 8 on the outer wall of the bellows 5 will just move to release it from the second positioning block 3. Under the action of the movement of the dust box 5, the synchronization rod 8 will push the second positioning block 3 to move, thereby realizing the positioning of the other two sides of the laminated material.

[0033] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
