Description

Technical Field

[0001] The utility model belongs to the technical field of additive manufacturing electronic circuits and relates to a device for pressing a multi-layer circuit board. Background Art

[0002] In the field of modern electronic manufacturing, the application of 3D printing technology is becoming more and more widespread, especially in the production of additive manufacturing electronics (AME) multilayer boards. AME multilayer boards use 3D printing technology to achieve rapid prototyping and complex design of electronic circuits. Compared with traditional printed circuit boards (PCBs), AME multilayer boards can achieve more compact and flexible circuit layouts in three-dimensional space.

[0003] However, when 3D printed AME multilayer boards are combined with traditional PCB boards to form AME multilayer composite boards, the assembly process requires extremely high precision. In some application scenarios, in order to meet space or performance requirements, multiple AME multilayer composite boards may need to be stacked for use. In this process, it is crucial to ensure the precise alignment and fixation of each layer of the board.

[0004] In the prior art, screws and nuts are usually used to fix the AME multilayer board. The screw passes through the conductive holes preset on the AME multilayer board, and then the nut is tightened to achieve fastening. However, this method has a significant problem: during the tightening of the nut, the AME multilayer board is prone to rotational deviation or misalignment due to uneven distribution of torque or improper operation. This deviation will not only reduce the performance of the circuit board, but may also cause failure of the entire device, leading to reliability and stability problems. Utility Model Content

[0012] According to an embodiment of the AME multi-layer composite board pressing device of the utility model, a slide groove is provided on the positioning block, and the bolt is in sliding cooperation and / or tight cooperation with the slide groove.

[0013] According to an embodiment of the AME multi-layer composite board pressing device of the utility model, the height of the positioning block is not less than the total height of the plurality of stacked AME multi-layer composite boards.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0041] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in the subsequent drawings.

[0042] See also Figures 1 to 4 The AME multi-layer composite board pressing device described in this embodiment is specially designed to improve the stability and accuracy of the AME multi-layer composite board during production and use. Figure 4 The AME multi-layer composite board includes a PCB board 401 and a multi-layer board 402. The multi-layer board 402 is provided with conductive holes. The PCB board 401 and the multi-layer board 402 are fixedly connected.

[0043] The AME multi-layer composite board pressing device includes a base plate 100, which is used to support and fix the entire pressing structure as the basic part of the device. The design of the base plate 100 needs to ensure sufficient rigidity and stability to withstand the pressure applied by the pressing assembly 300. A positioning assembly 200 for preventing the AME multi-layer composite board from rotating and a pressing assembly 300 for pressing a plurality of stacked AME multi-layer composite boards are installed on the base plate 100.

[0044] In order to prevent the AME multi-layer composite board from rotating during the tightening process, the positioning assembly 200 in this embodiment is designed to be detachable, so as to be adjusted according to the size and shape of the AME multi-layer composite board. The positioning assembly 200 includes positioning blocks 210, which are connected to the base plate 100 by bolts 220, and a slide groove 211 is provided on the positioning block 210 to achieve the sliding fit and / or tightening fit of the bolt 220. The height of the positioning block 210 is not less than the total height of the multiple stacked AME multi-layer composite boards. In a further embodiment, the positioning block 210 is an L-shaped plate, the horizontal section of the L-shaped plate is in contact with the base plate 100, and the height of the vertical section of the L-shaped plate is not less than the total height of the multiple stacked AME multi-layer composite boards. The positioning assembly 200 is multiple, Figures 2 to 4 The figure shows a situation where four positioning assemblies 200 are distributed and arranged on the deflection path of the AME multi-layer composite board during rotational deflection.

[0045] In one embodiment, the pressing assembly 300 is composed of a screw rod 310, a gasket 320 and a nut 330, and is used to fasten a plurality of stacked AME multi-layer composite boards. The screw rod 310 is vertically fixed on the base plate 100, and the gasket 320 is annular and provided with a through hole, and its inner diameter is larger than the major diameter of the screw thread of the screw rod 310 to ensure that the nut 330 can be smoothly tightened. The material of the gasket 320 is selected to be rubber or plastic to provide buffer protection to prevent damage to the AME multi-layer composite board during the fastening process.

[0046] In practical applications, the PCB board 401 and the multilayer board 402 are first fixedly connected through conductive holes to form an AME multilayer composite board. Then the AME multilayer composite board is placed on the substrate 100, and the position is aligned and fixed by the positioning component 200. Next, the screw 310, the gasket 320 and the nut 330 in the pressing component 300 are used to tighten the AME multilayer composite board to ensure that the layers are tightly combined without rotational deviation.

[0047] In actual application, it is recommended to use a torque wrench to rotate the nut 330. For example, the torque value is set to 100N / M, which can be combined with the AME multi-layer composite plate clamping device to achieve more precise clamping work.

[0048] The AME multi-layer composite board pressing device can effectively prevent the deviation between the AME multi-layer composite boards during the lamination process, thereby greatly improving the stability and success rate of the entire structure.
