Problems solved by technology

[0004] 1) The test time is very slow compared to the line speed of the product. The cycle time of the test is on the order of one or two minutes, while the line speed is on the order of ten seconds, which means that one line needs multiple testing machines
[0005] 2) The test equipment has a high degree of customization and a relatively large volume. The traditional construction method of test equipment is to stack instruments, which are often relatively large in size
[0006] Due to the above two limitations, it means that a production line needs multiple testing machines, which also requires multiple manipulators. One manipulator can only replace one labor at most, which is uneconomical from the perspective of investment.

Abstract

The invention discloses a circuit board testing system, which comprises a test tank, a material taking and putting mechanism and a control system, wherein the control system comprises a PC (personal computer) processor and a PLC (Programmable Logic Controller) control system. A box-type test machine comprises a box body, a drawer-type fixture, a fixture driving component and a test device, wherein one side of the box body is opened; the drawer-type fixture is arranged in the box body in an insertion mode from the opened side of the box body; the fixture driving component is connected with the drawer-type fixture and is used for driving the drawer-type fixture to pop out or retract back to the opened side of the box body; and the test device is arranged in the box body and is communicated with a circuit board to be tested. According to the circuit board testing system, the automation of the circuit board testing system can be realized.

Description

technical field [0001] The invention relates to a circuit board testing system, in particular to a circuit board testing system used for testing the main board of electronic products. Background technique [0002] In the circuit board assembly (PCBA) production line, testing is the link with the weakest degree of automation. For circuit board assembly, everything from brushing solder paste to reflow soldering is completed on the automatic line. Only when it comes to the testing process, its automation At present, on most production lines, testing is done manually by operators. If we observe a production line, we can see that the stations that occupy the most operators are often the test stations. [0003] Analyze the reasons for the low degree of test automation, the main reasons should be: [0004] 1) The test time is very slow compared to the line speed of the product. The cycle time of the test is on the order of one or two minutes, while the line speed is on the order o...
