Description

Technical Field

[0001] The present invention relates to the technical field of industrial inspection, and particularly relates to a multi-source inspection device and an inspection method. Background Art

[0002] The principle of industrial X-ray inspection equipment is as follows: the workpiece is irradiated by X-rays, converted into digital signals by an imager, and then restored into an image file by computer software, and then operations such as image judgment, marking, and storage are performed.

[0003] However, the current X-ray inspection equipment is basically customized for the industry (or by workpiece), generally only meeting the quality inspection and judgment of specific products or specific industries, with a relatively narrow scope of application, unable to adapt to changes in factors such as the specifications, angles, shapes, and materials (densities) of workpieces, and being limited by this; moreover, the existing X-ray inspection equipment can only perform planar imaging and cannot accurately locate and display the three-dimensional positions of defects and flaw points (or areas). In addition, the existing X-ray inspection equipment cannot complete the inspection of workpieces with a large thickness and a complex shape. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multi-source inspection device and an inspection method that can perform three-dimensional inspection on complex objects.

[0005] In order to solve the above technical problem, the technical solution adopted by the present invention is as follows:

[0006] A multi-source inspection device includes a ray inspection chamber and a conveyor belt passing through the ray inspection chamber, and a plurality of groups of inspection components are arranged in the ray inspection chamber;

[0007] The inspection component includes a ray source and a receiving plate for receiving the rays emitted by the ray source, and the rays of adjacent inspection components have an included angle;

[0008] The conveying path of the conveyor belt intersects with the rays emitted by the ray sources of the plurality of groups of inspection components.

[0009] In order to solve the above technical problem, another technical solution adopted by the present invention is as follows:

[0010] An inspection method for a multi-source inspection device includes the following steps:

[0011] Step 1: The conveyor belt conveys the workpiece through the ray inspection chamber;

[0012] Step 2: The ray source of the inspection component emits rays towards the workpiece, and the receiving plate receives the rays passing through the workpiece;

[0013] Step 3: The controller obtains the detection information through the receiving board, and determines whether there is any NG for the workpiece according to the detection information. If there is, it proceeds to the next step or Step 5; if not, it does not act.

[0014] Step 4: The controller controls the marking component to mark the NG.

[0015] Step 5: When the workpiece reaches the storage box, the controller controls the pushing component to push out the marked NG.

[0016] The beneficial effects of the present invention are as follows: Through multiple groups of detection components, and the rays of the multiple groups of detection components have an included angle, so that the workpieces conveyed by the conveyor belt can be detected and imaged at different angles, thereby ensuring the detection effect of the rays. It can adapt to most workpieces of different shapes and materials, and can also detect multiple groups of workpieces at the same time, effectively avoiding the situation of omission due to complex workpiece shapes resulting in detection dead angles.

[0049] Step 3: The controller obtains detection information through the receiving plate 12, and determines whether there is NG in the workpiece according to the detection information. If there is, the next step or Step 5 is executed; if not, no action is taken;

[0050] Step 4: The controller controls the marking component 3 to mark the NG;

[0051] Step 5: When the workpiece reaches the storage box 4, the controller controls the pushing-out component 5 to push out the marked NG.
