Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present invention.

As shown in fig. 1-3, an X-ray inspection system, hereinafter referred to as "the system". The system comprises a base assembly, wherein the base assembly comprises a supporting column 14 arranged on the ground, a frame 2 which is fixed on the supporting column 14, has no bottom and is provided with a containing space extending outwards from the middle of one side, a workbench 13 which penetrates through the frame 2 and extends towards two sides, an outer cover plate 10 placed on the frame 2, a lead door curtain 11 arranged above two sides of the frame 2, wheels 7 are arranged on the bottom of the supporting column 14, and a conveying belt 12 is arranged on the workbench 13; x-ray inspection subassembly, including installing sealing-tape machine 1 on workstation 13, the external installation is in photoelectric module 3 on the sealing-tape machine 1 is installed X-ray machine frame 4 of 2 inside one sides below of frame, a plurality of are installed the detector box 9 of 2 inside tops of frame and one side is installed the collimator 6 of 2 inside one sides of frame, and install the electrical installation frame 8 of 2 inside one side tops of frame, install shield panel 5 in one side that frame 2 has accommodation space, shield panel 5 one end with X-ray machine frame 4 links to each other, the other end with the upper end of collimator 6 links to each other.
