Description
Technical Field
[0001] The utility model relates to the technical field of PCBA performance testing, in particular to a PCBA performance testing device for flexible automated production. Background Art
[0002] PCBA is the core process in electronic manufacturing, which covers multiple links from circuit board design to component procurement, surface mounting, soldering, and testing. PCBA is not just a simple technical term; it represents a basic and complex process in the modern electronic manufacturing industry. It is to accurately install electronic components onto a printed circuit board according to specific design requirements to form a system or subsystem with complete electronic functions.
[0003] After the production of printed circuit boards, corresponding tests are usually required. Due to the different sizes of printed circuit boards, smaller circuit boards can be tested through manual clamping. However, for customized and larger circuit boards, a series of tests cannot be carried out through manual clamping because manual clamping tests will cause uneven stress on the circuit board and break it from the corners, thus increasing the production cost and test loss rate of the circuit board.
[0004] Therefore, we have designed a PCBA performance testing device for flexible automated production. Summary of the Utility Model
[0005] The purpose of the utility model is to propose a PCBA performance testing device for flexible automated production to solve the problem that larger customized circuit boards cannot be tested.
[0006] To achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A PCBA performance testing device for flexible automated production includes an aluminum alloy column. A rotating shaft for adjusting the testing angle of the circuit board is provided in the middle of the aluminum alloy column. A connector for improving the lateral adjustment stability is provided at the top of the aluminum alloy column. A placement board for temporarily placing the circuit board is provided on the aluminum alloy column. Thread adjusting shafts for lateral adjustment are symmetrically provided on the aluminum alloy column. A first limiting plate for fitting the circuit board is provided on the thread adjusting shaft. A traction rod for hanging the first limiting plate is provided on the connector. Clamping plates for locking the circuit board are symmetrically provided on the first limiting plate. Multi-section spring plates for adapting to the specifications of the circuit board are provided inside the clamping plates.
[0008] Preferably, first fixing ends are symmetrically provided on the aluminum alloy column. The thread adjusting shaft is fixedly connected to the first fixing end through a fastener. A second fixing end is provided at one end of the thread adjusting shaft.
[0009] Preferably, the first limiting plate is fixedly connected to the threaded adjustment shaft by welding.
[0010] Preferably, one end of the towing rod is fixedly connected to the second fixed end through an auxiliary shaft.
[0011] Preferably, pressing shafts for pressing the clamping plate are symmetrically arranged on the first limiting plate, a second limiting plate for supporting the clamping plate is arranged on the second fixed end, and the second limiting plate abuts against the clamping plate through a buffer shaft.
[0012] Preferably, both ends of the multi-section spring plate are fixedly connected to the clamping plate through fasteners, and a telescopic tube for improving the angular smoothness is arranged on the aluminum alloy column.
[0013] The beneficial effects of the present utility model are as follows:
[0014] 1. Through the arrangement of the clamping plate and the pressing shaft in the present utility model, during the clamping of the circuit board, the two sides of the circuit board can be clamped according to the length of the clamping plate, effectively avoiding breakage due to the circuit board being too large in size for a short clamping length. At the same time, the rubber surface inside the clamping plate can effectively reduce the wear on the surface of the circuit board caused by clamping, reducing the use effect of the circuit board, thereby reducing the manufacturing cost of the circuit board and improving the testing efficiency of the circuit board.
[0015] 2. Through the arrangement of the multi-section spring plate in the present utility model, the clamping plate can clamp circuit boards of different thicknesses, effectively improving the adaptability of the clamping plate to circuit boards of different specifications. Coupled with the clamping effect at the front end of the clamping plate, it can effectively reduce the loosening phenomenon of the circuit board during the flipping process and prevent it from falling off the clamping plate, thereby reducing the loss rate of circuit board testing.

DETAILED DESCRIPTION
[0021] Reference Figures 1 - 4 A PCBA performance testing device for flexible automated production includes an aluminum alloy column 1. The aluminum alloy column 1 is a long strip structure made of aluminum alloy material in the prior art. It is mainly used to support the circuit board and can achieve the effect of flipping the circuit board when necessary. The rotating shaft 2 is made of aluminum alloy material and has a smooth surface and is arranged in the middle of the aluminum alloy column 1, so that the upper half of the aluminum alloy column 1 can rotate on the lower half under the setting of the rotating shaft 2. The connector 3 is a limiting device used for hanging and dragging in the prior art, which completes the limitation and buffering of a certain structure through internal hydraulic components. The storage plate 4 is arranged in the lower half of the aluminum alloy column 1. The whole is made of metal material and is mainly used to temporarily place untested circuit boards. The circuit board described in this article is a printed circuit board after the PCBA process in the prior art.
[0022] The aluminum alloy column 1 is symmetrically provided with a threaded adjustment shaft 6 for lateral adjustment. The threaded adjustment shaft 6 is a component formed by laterally excavating an iron metal stick-shaped component through a threaded excavation tool in the prior art. It is mainly used to adjust the distance between the two clamping plates 13 to adapt to the specifications of the current circuit board. The aluminum alloy column 1 is symmetrically provided with a first fixed end 5. The first fixed end 5 is the basis for adjusting the threaded adjustment shaft 6 on the aluminum alloy column 1. The threaded adjustment shaft 6 is fixedly connected to the first fixed end 5 through a fastener. The fastener can limit one end of the threaded adjustment shaft 6 within the first fixed end 5, which can effectively prevent it from falling off due to excessive adjustment. A second fixed end 7 is provided at one end of the threaded adjustment shaft 6. The second fixed end 7 is used to fix the first limiting plate 9 and the second limiting plate 11.
[0023] A first limiting plate 9 for fitting the circuit board is provided on the threaded adjustment shaft 6. The first limiting plate 9 is a maximum height limiting component of the clamping plate 13 to prevent the clamping plate 13 from being over-adjusted and reducing the clamping force, thereby affecting the support and clamping effect of the circuit board. The first limiting plate 9 is fixedly connected to the threaded adjustment shaft 6 by welding, and welding can improve the connection strength between the two.
[0024] The connector 3 is provided with a traction rod 8 for hanging the first limiting plate 9. The traction rod 8 is a hanging traction component, which provides a supporting and hanging function for the second fixed end 7, thereby ensuring stability during adjustment. One end of the traction rod 8 is fixedly connected to the second fixed end 7 through an auxiliary shaft, and the auxiliary shaft enables the traction rod 8 to change with the length of the threaded adjustment shaft 6.
[0025] On the first limiting plate 9, clamping plates 13 for locking the circuit board are symmetrically arranged. The clamping plates 13 are made of aluminum alloy material and have a relatively long overall diameter, which can increase the contact area for clamping the circuit board to improve the stability during flipping. On the first limiting plate 9, pressing shafts 10 for pressing the clamping plates 13 are symmetrically arranged. The pressing shafts 10 are used to improve the limiting effect of the clamping plates 13 on the circuit board and prevent displacement during the flipping process. At the same time, the inner wall of the clamping plate 13 is provided with a rubber surface, which can effectively reduce the wear on the surface of the circuit board due to clamping and reduce the use effect of the circuit board. On the second fixed end 7, a second limiting plate 11 for supporting the clamping plate 13 is provided. The second limiting plate 11 is a bottom-retaining member for the clamping plate 13 on the other side, and the second limiting plate 11 abuts against the clamping plate 13 through a buffer shaft 12. The buffer shaft 12 has a shock-absorbing and buffering effect, which can effectively disperse the excess pressure of the pressing shaft 10, thereby reducing the phenomenon of damage on the surface of the circuit board.
[0026] Inside the clamping plate 13, there is a multi-section spring plate 14 for adapting to the specifications of the circuit board. The multi-section spring plate 14 is composed of multiple metal plates with the same structure and hollow interiors. At the same time, compression springs are provided in the hollow cavities, enabling the multi-section spring plate 14 to change according to the adjusted height of the clamping plate 13. Both ends of the multi-section spring plate 14 are fixedly connected to the clamping plate 13 through fasteners, and the fasteners can realize the disassembly and replacement function of the multi-section spring plate 14. On the aluminum alloy column 1, there is a telescopic tube 15 for improving the smoothness of the angle. The inside of the telescopic tube 15 is a hollow cavity for arranging the circuits of all driving components.
[0027] The working principle of the present utility model is as follows: First, according to the specifications of the circuit board, the length of the threaded adjustment shaft 6 is changed to make the clamping plates 13 adapt to the current circuit board. Subsequently, the flipping angle of the upper part of the aluminum alloy column 1 is changed, and then both ends or one side of the circuit board is clamped by the clamping plates 13 and fixed by the pressing shafts 10, and then the testing process can be carried out.
[0028] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
