Problems solved by technology

[0003] After the PCBA board is finished, the PCBA board needs to be tested for performance, usually a series of mechanical tests are required, including vibration test, plug-in test, line bending test and button life test, etc., and the PCBA board is currently being plugged in. During the test process, manual assistance is required to adjust and fix the position of the PCBA board according to the position of the port on the PCBA board, which increases manpower and material resources, reduces the efficiency of the test, and is vulnerable to unskilled operators during the test process. Affected, resulting in deviation damage to the PCBA board port due to inaccurate position angle adjustment during the test process, which increased the test cost, greatly reduced the test efficiency and the number of qualified PCBA boards, and could not adjust the port test position according to the position of the PCBA board port. In addition, during the bending test of the PCBA board, the damage to the PCBA board is aggravated due to the concentration of force, and the test process greatly reduces the stability and yield of the PCBA board, and it cannot be clamped and fixed according to the size of different test boards testing, which greatly increases the complexity of PCBA board testing
