Description

Technical Field

[0001] The utility model relates to the technical field of workpiece appearance detection, in particular to a workpiece appearance detection auxiliary tool. Background Art

[0002] Appearance inspection is a method mainly used to quickly identify the appearance defects of samples. High-precision workpieces usually need to be inspected for appearance. During appearance inspection, visual inspectors pick up the workpieces by hand or by using a magnetic strip to pick up the workpieces, and check the appearance defects of the workpieces under a magnifying glass. Usually, visual inspectors use the method of manual direct picking to perform appearance inspection. For small ferromagnetic workpieces, visual inspectors also use a magnetic strip to pick up the workpieces for appearance inspection. However, the above-mentioned appearance inspection aids or ordinary magnetic strip suction aids have the following defects: (1) Manual picking and placing of parts leads to low efficiency and high labor intensity for workers; (2) Ordinary magnetic strips cannot be used for thin-walled special parts, mainly because: the magnetic strip is weak in magnetism and cannot attract the workpiece; when the magnetic strip is strong in magnetism, the workpiece will be sucked crooked; when the magnetism is strong, the workpiece is not easy to detach from the magnetic strip, and the workpiece cannot be smoothly placed in the tray.

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] Example:

[0023] This embodiment introduces a workpiece appearance inspection auxiliary tool.

[0024] Combined with Figure 1 , 2 As shown in the figure, it is a structural schematic diagram of a workpiece appearance detection auxiliary tool of the utility model. Figure 2 The present invention is a schematic diagram of the auxiliary structure of a workpiece appearance inspection auxiliary tool.

[0025] A workpiece appearance inspection auxiliary tool, comprising: an auxiliary part 1, with handles 5 connected to both ends of the auxiliary part 1;

[0026] A magnet 2, wherein the magnet 2 is fixed to the auxiliary part 1 through a locking nut 4;
