Description

Technical Field

[0001] The utility model relates to the technical field of optical screening machines, in particular to a turntable structure of an optical screening machine. Background Art

[0002] An optical screening machine is a machine vision inspection machine. It uses an industrial camera to convert the target to be inspected into an image signal, which is then converted into a digital signal based on pixel distribution, brightness, color and other information. The image processing system performs various operations on these signals to extract the target's features, such as area, quantity, position, and length. The results are then output based on preset tolerances and other conditions, including size, number, pass / fail, presence / absence, etc., to achieve automatic detection and identification functions.

[0003] Optical screening machines are mostly used for automatic inspection of hardware, especially small parts such as screws and nuts. The optical screening machine includes a feeding device, a turntable structure, a detection device and a receiving device. The feeding device feeds the screws to the turntable structure, the detection device detects the screws on the turntable, and the receiving device classifies and collects the screws according to the detection results. The turntable structure of some existing optical screening machines is relatively simple and does not have a position adjustment function. When the feeding device transports the screws to the turntable, the position of the screws on the turntable may deviate, causing the screws to deviate from the corresponding position of the detection device, resulting in some screws cannot be fully detected, thereby affecting the detection quality. Therefore, a turntable structure of an optical screening machine is proposed to address the above problems. Utility Model Content

[0027] Working process: Turn on the power before use. The feeding device, detection device and receiving device of the optical screening machine require electricity. The driving motor 4, the first adjusting motor 9 and the second adjusting motor 10 of the device are all electrical instruments. The feeding device fixed to the bracket 2 is located above the right half of the glass turntable 5, the receiving device fixed to the bracket 2 is located above the left half of the glass turntable 5, and the detection device fixed to the bracket 2 is located above the front half of the glass turntable 5. A movable receiving box located on the base 1 is provided directly below the receiving device and the detection device. When the optical screening machine is in use, the driving motor 4 fixed to the top of the support seat 3 drives the glass turntable 5 to rotate. Looking from top to bottom, the glass turntable 5 rotates counterclockwise, and the screws to be detected can be delivered to the On the glass turntable 5, the screws on the turntable are inspected by the detection device. If the detection is unqualified, the detection device sucks the screw forward through the electromagnetic suction head, so that the screw falls into the material receiving box at the lower front side of the glass turntable 5.
