Description

Technical Field

[0001] The utility model relates to the technical field of PCBA detection, in particular to a PCBA detection device for a wireless Bluetooth connected keyboard. Background Art

[0002] PCBA testing is an important means to strictly control the quality of shipments. In order to ensure the high quality and reliability of PCBA, PCBA manufacturers must inspect circuit boards at different stages of the manufacturing and assembly process to eliminate surface defects.

[0003] After searching, the application with patent announcement number CN220525953U discloses a wireless Bluetooth connected keyboard PCBA detection device, including a base and a PCBA circuit board. The upper end surface of the base is fixedly connected to a first side panel and a second side panel. The inner side surfaces of the first side panel and the second side panel are rotatably connected to a rotating shaft. The inner side surfaces of the two rotating shafts are each installed with a first square plate. The inner side surfaces of the two first square plates are each connected with a first connecting smooth rod and a second connecting smooth rod. In this way, PCBA circuit boards of different sizes can be clamped, thereby improving the practicality of the device.

[0004] However, due to the setting of the card plates and the connecting springs, when the circuit board is inserted between the card plates, the distance between the card plates must be greater than the length of the circuit board. Then, through the connecting spring and the slide plate, the slide plate drives the connecting spring to move, thereby clamping the circuit board. The clamping force of the connecting spring is not easy to control, which can easily cause damage to the circuit board. At the same time, the electric push rod drives the detection head to move, thereby fitting the detection head on the circuit board for detection, and cannot detect other positions of the circuit board, resulting in poor detection effect.

[0005] Therefore, we proposed a wireless Bluetooth connected keyboard PCBA detection device. Utility Model Content
