Description

Technical Field

[0001] This utility model relates to the field of electronic circuit board testing technology, and in particular to a testing fixture for PCBA production. Background Technology

[0002] PCBA (Printed Circuit Board Assembly) refers to the process of mounting various electronic components (such as resistors, capacitors, chips, etc.) onto a printed circuit board (PCB) using surface mount technology (SMT) or through-hole technology (DIP), followed by soldering and testing, ultimately forming a circuit board assembly with a specific function.

[0003] Production testing refers to the process of verifying the functionality, evaluating the performance, and inspecting the quality of electronic products during the manufacturing process, through a series of testing methods and means, in order to ensure the reliability and stability of the products in actual use.

[0004] Functional testing of PCBA can only be conducted after it is fully assembled into the device.

[0005] Because the equipment consists of multiple PCBAs, the functionality of each PCBA cannot be tested individually before complete assembly. Testing them together without ensuring the functionality of each PCBA significantly increases the difficulty of fault location and may even lead to rework and disassembly of the entire machine due to a single PCBA failure. This is not only time-consuming and labor-intensive but also increases the risk of component damage during rework, reducing the reliability and stability of the equipment.

[0006] The assembly of the entire machine makes it inconvenient to measure, locate, and repair faulty individual boards. Summary of the Invention

[0007] The present invention aims to provide a PCBA testing fixture platform that is easy to load and unload, has a simple structure, and is open, in order to solve the problems of high rework rate, low efficiency, and inability to repair and locate in the prior art.

[0008] The purpose of this utility model is achieved through the following technical solution: a PCBA production testing fixture, including a base, a tray, a back plate, a fan board slot, a main control board slot, a business interface board, and hand-tightening screws.

[0009] The tray is located on top of the base and has threaded holes. The hand-tightening screws are used to secure the motherboard PCBA to the tray.

[0010] The top front of the base is equipped with a vertically arranged service card guide rail, and the service interface board can move vertically along the service card guide rail; the service interface board is used to connect the main board PCBA and the test instrument, and the front of the service interface board is equipped with a board interface for cable / fiber optic connection.

[0011] The base has a fan plate slot and a main control board slot on one side;

[0012] A back plate is fixedly installed on the top rear side of the base, and the back plate connector is fixedly connected to the back plate.

[0013] Preferably, it also includes a wrench and a connecting rod. The wrench is provided on one side of the base, the tray is rotatably connected to the connecting rod, and the connecting rod is rotatably connected to the wrench. The part of the wrench that extends out of the base is provided with a vertical pulling part.

[0014] Preferably, the tray and the connecting rod are rotatably connected by screws, and the connecting rod and the wrench are rotatably connected by screws.

[0015] Preferably, the service card guide rail is stepped, and the slot is composed of the guide rail and the base. The structural components of the service card are inserted into the guide rail slot for insertion and removal.

[0016] Preferably, the base and the tray are connected by a bracket, the bracket is fixedly connected to the base, and screws are used to connect the tray and the bracket.

[0017] Preferably, the backplate is fixed to the tooling base with screws, and the backplate connector is soldered to the backplate.

[0018] Preferably, the back end of the service interface board is provided with gold fingers for inserting into the corresponding connector on the motherboard PCBA.

[0019] This invention eliminates the need to disassemble the motherboard PCBA, backplane PCBA, fan, and main control board. The motherboard PCBA can be assembled without additional tools. This invention significantly simplifies the PCBA assembly process during testing, reduces overall testing time, greatly improves production testing efficiency, and meets the needs of mass production testing.

Detailed Implementation

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0027] like Figure 1-4 As shown, this utility model discloses a test fixture for PCBA production, including a base 1, a tray 10, a back plate 4, a fan board slot 12, a main control board slot 13, a service interface board 7, a wrench 5, and a hand-tightening screw 8.

[0028] The base 1 has a fan board slot 12 and a main control board slot 13 on one side, which are used to install the fan board 2 and the main control board 3, respectively. A back plate 4 is provided on the rear top side of the base 1. The back plate 4 is fixed to the tooling base 1 with screws, and a back plate connector is soldered to the back plate 4. A wrench 5 is provided on one side of the base 1. A longitudinally arranged service card guide rail 14 is provided on the front top side of the base 1. The service card guide rail 14 is used for inserting and removing the service interface board 7. The service interface board 7 is used to connect the main board PCBA 6 to the test instrument. The test instrument is connected to the front panel interface of the service interface board 7 via a cable / fiber optic cable. The service card guide rail is stepped, and the guide rail groove is composed of a guide rail and a base. The structural components of the service interface board 7 are inserted and removed into the guide rail groove. Because the service interface board 7 and the main board PCBA 6 overlap vertically, when installing or removing the main board PCBA 6, the service interface board 7 needs to be moved forward out of the main board PCBA 6 first. In use, after the main board PCBA 6 is connected to the tray 10, the service interface board 7 is pushed from front to back along the service card guide rail 14, and the gold fingers of the service interface board 7 are inserted into the corresponding connectors on the main board PCBA 6.

[0029] Figure 3 The base is placed upside down.

[0030] The base 1 and the tray 10 are connected by a bracket 9, which is fixedly connected to the base 1. Screws are used to connect the tray 10 and the bracket 9. The tray 10 is built into the base 1. A large hole corresponding to the shape of the tray 10 is opened on the top of the base 1, exposing the tray 10. In this way, the tray 10 is a movable part relative to the base 1, supported by a guide rail and the bracket 9.

[0031] The tray 10 is used to mount the motherboard PCBA 6, and the hand-tightening screw 8 is used to fasten the motherboard PCBA 6 to the tray 10. The hand-tightening screw 8 on the tray 10 protrudes above the top surface of the base 1, thus allowing the motherboard PCBA 6 to be mounted on the tray 10. The tray 10 and the connecting rod 11 are rotatably connected by screws, and the connecting rod 11 is rotatably connected to the wrench 5 by screws. The wrench 5 extends out of the base 1, and the wrench 5 has a vertical pulling part outside the base 1.

[0032] Thus, tray 10 is connected to wrench 5 via connecting rod 11. When wrench 5 is turned, connecting rod 11 moves tray 10 back and forth and left and right a certain distance, so the motherboard PCBA 6 mounted on tray 10 will move back and forth with tray 10, realizing the plug-in relationship between the gold fingers of motherboard PCBA 6 and the backplane connector on the tooling. Fixing motherboard PCBA 6 only requires tightening with hand screws 8.
