Description

Technical Field

[0001] The invention belongs to the technical field of computer detection, and in particular relates to a computer power-on detection device. Background Art

[0002] Computer, commonly known as computer, is a modern electronic computing machine used for high-speed computing. It can perform numerical calculations, logical calculations, and has storage and memory functions. It is a modern intelligent electronic device that can run according to programs and automatically and quickly process massive amounts of data. It is composed of a hardware system and a software system. In order to achieve the effect of continuous detection, the existing computer power-on detection device generally needs to use a conveyor belt to transport materials. However, it is difficult to ensure that the computer is neatly placed during the loading process, which may easily lead to the detection components not being accurately docked with the computer, affecting the accuracy of the detection results.

[0003] To this end, a Chinese patent with patent number CN221746559U discloses a computer power-on detection device, including a base, a conveyor belt device, a clamping and straightening mechanism and a bracket are fixed on the upper end surface of the base, the lower side of the top inside the bracket is connected to the multimeter through a third electric telescopic column, and contact pieces are symmetrically fixed on both sides of the lower end surface of the multimeter. The conveyor belt device can be used to transport the computer to the right, making the entire detection operation more orderly and efficient. After the computer reaches the bottom of the support plate, the support plate moves downward with the first movable frame. When the second movable frame moves upward, the card block leaves the card slot, thereby unlocking the limit rod, and the limit rod and the clamp plate automatically pop open. The clamp plate can clamp and straighten the computer to ensure that the computer is neatly placed. After the clamp plate is removed, the computer can continue to be transported to the right. After the multimeter is lowered, the multimeter and the contact piece can be used in combination to detect the power-on performance of the computer.

[0004] However, the above device can only perform a straightening operation on one computer at a time and then test it, which is time-consuming and easily affects the continuity of the computer power-on detection work, and then affects the work efficiency of the computer power-on detection.
