Description

Technical Field

[0001] The utility model relates to the technical field of multi-layer circuit boards, in particular to a multi-layer circuit board which is convenient for stacking and pressing. Background Art

[0002] The manufacturing method of multi-layer circuit boards generally starts with making the inner layer graphics first, then using printing and etching to make a single-sided or double-sided substrate, and incorporating it into the specified interlayer, and then heating, pressurizing and bonding it.

[0003] After searching, a Chinese patent with publication number CN213403634U discloses a multi-layer circuit board, the technical key points of which are: solving the problem that the multi-layer circuit board is prone to generate a lot of heat after long-term use, and the heat dissipation efficiency is slow, which is easy to affect the use of the circuit board. At the same time, the connection stability of the multi-layer circuit board is poor, and the multi-layer circuit board is prone to dislocation during use or later processing, thereby affecting the use of the multi-layer circuit board.

[0004] However, when manufacturing the above-mentioned scheme and the existing multi-layer circuit boards, the multi-layer circuit boards need to be stacked and pressed. When stacking and pressing the above-mentioned scheme and the existing multi-layer circuit boards, the operation is cumbersome and the positioning is inaccurate, which can easily lead to uneven pressing of the circuit boards. In addition, there is a lack of structure that can buffer the circuit boards during the pressing process. When the pressing force is too large, it is easy to cause damage to the surface of the circuit board.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the above background technology, the prior art has the disadvantages that when stacking and pressing multi-layer circuit boards, the operation is cumbersome and the positioning is inaccurate, which easily leads to the shortcomings and defects of uneven pressing of the circuit boards.

[0007] The utility model discloses a multi-layer circuit board which is convenient for stacking and pressing, comprising a bottom plate and a circuit board body, the upper surface of the bottom plate is provided with sliding grooves 1 and sliding grooves 2 which are arranged at equal distances, the inner wall of each sliding groove 1 is slidably connected with a sliding block 1, the upper surface of each sliding block 1 is fixedly connected with a vertical rod, a side of each vertical rod close to each other is provided with sliding grooves 3, the inner wall of each sliding groove 3 is slidably connected with a sliding block 3, the inner wall of each sliding block 3 is threadedly connected with a threaded rod, the outer surface of each sliding block 3 is fixedly connected with a card block, the upper surface of the circuit board body is provided with two card slots, the inner wall of each card slot is slidably connected with the outer surface of the corresponding card block.

[0008] Furthermore, the inner wall of each sliding block 1 is slidably connected to a guide rod, and the side of each sliding block 1 away from each other is fixedly connected to a spring, and the other end of each spring and guide rod is fixedly connected to the inner wall of the corresponding sliding groove 1.

[0009] Furthermore, the inner wall of each of the sliding grooves 2 is slidably connected to a sliding block 2, and the upper surface of each of the sliding blocks 2 is fixedly connected to a clamping block.

[0010] Furthermore, the inner wall of the bottom plate is rotatably connected to two bidirectional screws, and the outer surface of each bidirectional screw is threadedly connected to the inner wall of the corresponding sliding block 2.

[0011] Furthermore, a gear is fixedly connected to the outer surface of each bidirectional screw, a toothed belt is provided inside the base plate, and each gear is meshed with the toothed belt.

[0012] Furthermore, elastic sheets arranged at equal distances are provided above the bottom plate, and an elastic steel sheet is fixedly mounted on the bottom surface of each elastic sheet.

[0013] Furthermore, two limiting grooves are provided on the upper surface of each elastic sheet, the inner wall of each limiting groove is slidably connected to a limiting block, and the bottom surface of each limiting block is fixedly connected to the upper surface of the bottom plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model sets a sliding block 1, a vertical rod, a threaded rod, a card block and other components. By moving the corresponding sliding block 1, the corresponding vertical rod is driven to move, and the vertical rod is brought into contact with the circuit board body. By rotating the corresponding threaded rod, the corresponding sliding block 3 is driven to move.

[0016] 2. The utility model places the circuit board body on the surface of the corresponding elastic sheet by arranging components such as elastic sheets, limiting grooves, elastic steel sheets, and limiting blocks. When the upper extrusion component squeezes the circuit board body, the circuit board body drops and compresses the elastic sheet. The limiting effect of the elastic sheet is achieved through the connection between the limiting groove and the limiting block. At this time, the elastic sheet compresses the elastic steel sheet. The buffering effect of the circuit board body is achieved through the rebound of the elastic sheet and the elastic steel sheet. The impact force received by the multi-layer circuit board can be buffered, thereby protecting the circuit board body. BRIEF DESCRIPTION OF THE DRAWINGS
