For example, chinese patent publication No. CN101281145B discloses an X-ray detection apparatus, which can only detect a single-specification product tray, cannot be compatible with other-size product trays, has certain limitations, and is difficult to achieve higher detection efficiency. Therefore, it is necessary to provide an automatic X-ray detection apparatus capable of ensuring motion synchronism, being compatible with trays of various specifications, and improving detection efficiency and detection yield.
