Description

Technical Field

[0001] This application belongs to the field of silicon steel sheet production technology for motor cores, and specifically relates to a visual inspection device for silicon steel sheets for motor cores. Background Technology

[0002] During the production process of silicon steel sheets for motor cores, it is necessary to keep a factory record. Specifically, this is done by taking pictures of the appearance and labels of the silicon steel sheets with a camera so that quality inspectors can observe them and thus control the quality of the silicon steel sheets.

[0003] In existing technology, the label on the silicon steel sheet is usually fixed at the edge of the silicon steel sheet. Therefore, after the camera takes a picture from a high position, it is necessary to use a robotic arm to move it downwards and move it a certain distance horizontally so that the camera is facing the label.

[0004] The inventors discovered that the movement process of the robotic arm is quite complex, usually requiring at least two sets of drive components to work together, resulting in high production, maintenance, and repair costs, which hinders its market adoption. Utility Model Content

Furthermore, the label on the silicon steel sheet is located at its left or right end. Based on this, the fixing arm 1 is located on the left or right side of the translational area of ​​the silicon steel sheet, specifically on the side where the label is located. The fixing arm 1 has a lifting seat 4 that is slidably connected to it in the vertical direction, and a locking structure 5 is provided between the lifting seat 4 and the fixing arm 1.
