Description

Technical Field

[0001] This utility model relates to the field of circuit board production equipment technology, specifically a circuit board lamination and positioning fixture. Background Technology

[0002] Circuit boards, also known as printed circuit boards, are core components that provide mechanical assembly support and electrical connections for various electronic systems. They also carry out signal transmission, signal reception and power supply for electronic devices. Circuit boards need to be positioned using a device before being laminated.

[0003] The device can position the stacked circuit boards. Existing circuit board stacking positioning devices can only achieve single-dimensional positioning and simple constraint by the edge. When the stacked circuit boards are moved, the layers are prone to relative shaking due to vibration, inertia and other factors, which leads to interlayer displacement. This displacement will directly cause the pads, vias and other key positions of each layer of the circuit board to be unable to be accurately aligned, which will seriously affect the accuracy of subsequent stacking and processing, and even cause quality problems such as short circuits and open circuits, thus affecting the subsequent stacking and pressing of the circuit boards. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] This utility model provides a circuit board lamination and positioning fixture, which aims to solve the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a circuit board lamination and positioning fixture, comprising a worktable, a positioning plate mounted on the worktable surface, a fixing mechanism mounted inside the positioning plate, connecting frames mounted on both sides of the positioning plate, a fixing plate mounted on one side of the connecting frame via a hinge structure, a spring rod mounted at the bottom of the center position of the fixing plate, a bracket mounted on one side of the top of the worktable, and a pressing mechanism mounted on the inner top of the bracket.

[0008] As a preferred technical solution of this application, a linear guide mechanism is installed inside the workbench, and a positioning plate is connected to the outside of the linear guide mechanism.

[0009] As a preferred technical solution of this application, positioning blocks are installed at the four corners of the positioning plate surface, and the positioning blocks are in the shape of ∟.

[0010] As a preferred technical solution of this application, the fixing mechanism includes a suction plate disposed inside the positioning plate, and a suction mechanism is installed on the side of the outer wall of the positioning plate. The input end of the suction mechanism is connected to the suction plate and the spring rod.

[0011] As a preferred technical solution of this application, the air outlet of the suction mechanism is equipped with a connecting pipe, and an air guide plate is installed on one side of the connecting pipe.

[0012] As a preferred technical solution of this application, the top of the spring rod is rotatably connected to a fixing plate, and a protective block is provided on the inner top of one end of the fixing plate.

[0013] As a preferred technical solution of this application, the bracket includes a hydraulic rod disposed above the fixed plate and located at the top of the bracket, a pressing plate is installed at the moving end of the hydraulic rod, and a pressure head is installed at the bottom end of the pressing plate.

[0014] (III) Beneficial Effects

[0015] 1. This utility model utilizes a positioning plate, connecting frame, fixing plate, protective block, spring rod, and fixing mechanism in conjunction. When the fixing mechanism is activated, a pressure difference is created between the surface of the positioning plate and the circuit board through suction, firmly adhering the bottom layer and stacked circuit boards to the surface of the positioning plate. This achieves horizontal fixation of the circuit boards from the bottom, effectively preventing horizontal displacement of the circuit boards during subsequent operations. Simultaneously with the suction action of the fixing mechanism, the spring rod generates a downward driving force due to the air pressure difference created by the suction, causing the fixing plate, which is connected to the connecting frame via a hinge structure, to rotate and move downward. As the fixing plate rotates, it gradually approaches the top of the circuit board, achieving fixation of the top of the circuit board. The bottom fixing mechanism, together with the top spring rod and fixing plate, forms a coordinated fixing effect, stably clamping the multi-layer circuit boards onto the positioning plate, preventing loosening or displacement during the pressing process, thus ensuring that the subsequent stacking and pressing of the circuit boards will not be affected.

[0016] 2. This utility model uses a connecting pipe and an air guide plate in conjunction. The suction mechanism is activated by connecting its input end to the suction plate and spring rod inside the positioning plate to form a negative pressure environment. The suction plate can firmly adhere the bottom of the circuit board to the surface of the positioning plate. At the same time, the connecting pipe installed at the air outlet of the suction mechanism guides the exhaust airflow to the air guide plate. The air guide plate can guide the airflow around the circuit board, which helps to disperse dust or impurities that may exist before lamination, reduce the impact on the lamination quality of the circuit board, and thus improve the quality of the subsequent lamination of the circuit board.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments;

[0025] Example:

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Please refer to the accompanying drawings. Figures 1 to 5 Please refer to the circuit board lamination and positioning fixture provided in this application. Figure 1 , Figure 2 and Figure 5 The system includes a workbench 1, a positioning plate 2 installed on the surface of the workbench 1, a fixing mechanism 5 installed inside the positioning plate 2, connecting frames 201 installed on both sides of the positioning plate 2, a fixing plate 202 installed on one side of the connecting frame 201 via a hinge structure, a spring rod 203 installed at the bottom of the center position of the fixing plate 202, a bracket 3 installed on one side of the top of the workbench 1, and a pressing mechanism 4 installed on the inner top of the bracket 3.

[0027] Specifically, the workbench 1 provides a stable mounting platform for components such as the positioning plate 2 and the bracket 3, ensuring the structural stability of the entire fixture during operation. When performing circuit board stacking and pressing, the multiple layers of circuit boards are first placed sequentially on the positioning plate 2, providing initial positioning and ensuring accurate reference positions during stacking. Then, the fixing mechanism 5 inside the positioning plate 2 is activated, creating a pressure difference between the surface of the positioning plate 2 and the circuit boards through suction. This firmly adheres the bottom layer and stacked circuit boards to the surface of the positioning plate 2, achieving horizontal fixation of the circuit boards from the bottom and effectively preventing horizontal displacement during subsequent operations. The suction effect of the fixing mechanism 5 further contributes to this stability. Simultaneously, the spring rod 203 generates a downward driving force at its moving end due to the air pressure difference created by suction, causing the fixing plate 202, which is connected to the connecting frame 201 via a hinge structure, to rotate and move downward. As the fixing plate 202 rotates, it gradually approaches the top of the circuit board, thus fixing the top of the circuit board. At this time, the fixing mechanism 5 at the bottom, together with the spring rod 203 and the fixing plate 202 at the top, form a coordinated fixing effect, stably clamping the multi-layer circuit board onto the positioning plate 2, preventing it from loosening or shifting during the pressing process. Finally, the pressing mechanism 4 at the top of the bracket 3 on one side of the top of the workbench 1 is activated, moves downward, and applies pressure to the fixed multi-layer circuit board, completing the lamination pressing operation.

[0028] Please refer to this carefully. Figure 1 and Figure 2 The workbench 1 is equipped with a linear guide mechanism 101, and the outer side of the linear guide mechanism 101 is connected to a positioning plate 2.

[0029] Please refer to this carefully. Figure 5 Positioning blocks 6 are installed at the four corners of the surface of the positioning plate 2. The positioning blocks 6 are ∟-shaped.

[0030] Specifically, to position the circuit board, the linear guide mechanism 101 provides guidance and support for the movement of the positioning plate 2. Through the sliding cooperation between the internal slider and the guide rail, the positioning plate 2 moves smoothly along the set trajectory. When the positioning position needs to be adjusted according to the size of the circuit board, the linear guide mechanism 101 drives the positioning plate 2 to adjust its position on the worktable 1, ensuring that the positioning plate 2 can be accurately moved to a position that matches the circuit board. The ∟-shaped positioning blocks 6 installed at the four corners of the positioning plate 2 form a positioning space that matches the four corners of the circuit board. The ∟-shaped structure can simultaneously limit two adjacent edges of the circuit board. When the circuit board is placed on the positioning plate 2, the four corners of the circuit board will respectively fit with the four ∟-shaped positioning blocks 6. The ∟-shaped positioning blocks 6, through close contact with the four corners of the circuit board, provide all-round positioning constraints on the circuit board from the four corners, preventing the circuit board from shifting horizontally during the lamination and pressing process.

[0031] Please refer to this carefully. Figure 4 The fixing mechanism 5 includes a suction plate 502 disposed inside the positioning plate 2, and a suction mechanism 501 is installed on the side of the outer wall of the positioning plate 2. The input end of the suction mechanism 501 is connected to the suction plate 502 and the spring rod 203.

[0032] Please refer to this carefully. Figure 4 and Figure 5 The exhaust port of the suction mechanism 501 is equipped with a connecting pipe 7, and an exhaust plate 701 is installed on one side of the connecting pipe 7.

[0033] Please refer to this carefully. Figure 4 A fixing plate 202 is rotatably connected to the top of the spring rod 203, and a protective block 2021 is provided on the inner top of one end of the fixing plate 202.

[0034] Specifically, to assist in fixing the circuit board, after the circuit board is placed on the positioning plate 2 and initially positioned by the positioning block 6, the fixing mechanism 5 starts working, and the suction mechanism 501 is activated. Its input end is connected to the suction plate 502 and the spring-loaded rod 203 inside the positioning plate 2 to form a negative pressure environment. The suction plate 502 can firmly adhere the bottom of the circuit board to the surface of the positioning plate 2, preventing the circuit board from shifting due to slight shaking during the stacking process. The negative pressure inside the spring-loaded rod 203 can further enhance the adsorption effect on the circuit board. While suction is being performed, the fixing plate 2 at the top of the spring-loaded rod 203... 02. Rotate so that one end of the fixing plate 202 covers the top edge of the circuit board. The protective block 2021 at the top of the fixing plate 202 contacts the surface of the circuit board. The pressure of the fixing plate 202 further fixes the circuit board. The protective block 2021 can prevent the fixing plate 202 from directly and rigidly contacting the circuit board, preventing damage to the surface or components of the circuit board. In addition, the connecting pipe 7 installed at the air outlet of the suction mechanism 501 guides the exhaust airflow to the air guide plate 701. The air guide plate 701 can guide the airflow around the circuit board, which helps to disperse dust or impurities that may exist before lamination and reduce the impact on the lamination quality of the circuit board.

[0035] Please refer to this carefully. Figure 3 The bracket 3 includes a hydraulic rod 401 located at the top of the bracket 3 above the fixed plate 202. The moving end of the hydraulic rod 401 is equipped with a pressing plate 402, and the bottom end of the pressing plate 402 is equipped with a pressure head 403.

[0036] Specifically, in order to achieve the pressing fixture for the circuit board, after the fixing mechanism 5 completes the positioning and fixing of the multi-layer circuit board, the hydraulic rod 401 at the top of the bracket 3 is activated. The moving end of the hydraulic rod 401 extends downward, driving the pressing plate 402 installed at the moving end to move downward synchronously. The pressure head 403 installed at its bottom end directly contacts the top layer circuit board. As the hydraulic rod 401 continues to extend, the pressing plate 402 drives the pressure head 403 to gradually approach and squeeze the multi-layer circuit board, and the pressure generated by the hydraulic rod 401 is evenly transmitted to the circuit board stack, thus completing the pressing fixture for the circuit board. After the pressing is completed, the moving end of the hydraulic rod 401 retracts upward, driving the pressing plate 402 and the pressure head 403 to detach from the circuit board.

[0037] Working Principle: The operator places the multi-layer circuit boards sequentially on the positioning plate 2. The four corners of the circuit boards abut against the ∟-shaped positioning blocks 6 at the four corners of the positioning plate 2. The ∟-shaped structure simultaneously limits the adjacent edges of the circuit boards, achieving all-round constraint from the four corners. At the same time, the suction mechanism 501 starts working. Its input end connects to the suction plate 502 inside the positioning plate 2 and the spring empty rod 203, forming a negative pressure environment. The suction plate 502 uses negative pressure to firmly adhere the bottom layer and stacked circuit boards to the surface of the positioning plate 2, achieving horizontal fixation from the bottom and preventing the circuit boards from shifting due to shaking. The spring empty rod 203 generates a downward driving force due to the internal negative pressure, causing the fixing plate 202, which is connected to the connecting frame 201 through a hinge structure, to rotate and move downward. The fixing plate 202 gradually approaches the top of the circuit boards, and the inner top protective block 2021 at one end contacts the surface of the circuit boards, applying pressure from the top. This works in conjunction with the bottom suction fixation to stably clamp the multi-layer circuit boards. The airflow from the exhaust port of the suction mechanism 501... The airflow is guided to the air intake plate 701 through the connecting pipe 7. The air intake plate 701 directs the airflow to the area around the circuit board, dispersing any dust or impurities that may be present before pressing. Then, the linear guide mechanism 101 inside the workbench 1 drives the positioning plate 2 to move smoothly along the set trajectory. When the circuit board moves to the bottom of the pressure head 403, the hydraulic rod 401 at the top of the bracket 3 is activated, and its moving end extends downward, driving the pressing plate 402 and the pressure head 403 at the bottom to move downward simultaneously. The pressure head 403 directly contacts the top circuit board. As the hydraulic rod 401 continues to extend, the pressure is evenly transmitted to the circuit board stack through the pressing plate 402, completing the stacking and pressing of multiple circuit boards. After pressing, the moving end of the hydraulic rod 401 retracts upward, causing the pressing plate 402 and the pressure head 403 to detach from the circuit board. The suction mechanism 501 stops working, the negative pressure disappears, the spring rod 203 resets, and the fixing plate 202 rotates upward to open. The operator can then remove the pressed circuit board, and the tooling returns to its initial state, ready for the next batch of work.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
