Description

Technical Field

[0001] This utility model relates to the field of circuit board testing, and in particular to a testing device for the production of intelligent control circuit boards for vacuum cleaner motors. Background Technology

[0002] The intelligent control circuit board for a vacuum cleaner motor is the "nerve center" of the vacuum cleaner, responsible for receiving instructions, sensing operating conditions, and precisely controlling motor operation. It is the core component for realizing the intelligence and efficiency of a vacuum cleaner. Before leaving the factory, the circuit board undergoes numerous performance tests, including appearance and dimensional inspection, electrical performance testing, mechanical performance testing, and environmental adaptability testing. Mechanical performance testing includes bending strength testing, impact resistance testing, and collision resistance testing to ensure that its mechanical performance meets standards.

[0003] Due to the special usage scenarios of vacuum cleaners, the intelligent control circuit board of the vacuum cleaner motor vibrates a lot during operation. The circuit board itself is prone to damage when exposed to vibration for a long time, and the solder joints on the circuit board may fall off due to insufficient stability, thus affecting the service life of the vacuum cleaner motor.

[0004] Therefore, we propose a device for testing the vibration resistance of circuit boards themselves and the vibration resistance of their solder joints. Utility Model Content

It mainly converts its own rotational motion into periodic mechanical vibration and is widely used in various scenarios that require vibration operation. In this device, the vibration motor 123 can drive the circuit board body 124 to vibrate, thereby simulating a vibration environment and testing the stability of the circuit board and the firmness of the solder joints.

[0027] A fixing mechanism 2 is provided on the vibrating part 12. The fixing mechanism 2 includes a moving part 21 provided on the vibrating part 12.
