Vision test device

Abstract

The invention discloses a vision test device comprising a machine frame, a conveyor belt, mobile phone positioning clamps, a vision test mechanism and a removal device. The horizontal conveyor belt isinstalled on the machine frame. The multiple positioning clamps used for positioning mobile phones are installed on the conveyor belt. The vision test mechanism is installed at the position, corresponding to one side of the conveyor belt, of the machine frame. The removal device used for removing defective products is further installed on the machine frame. The removal device comprises a horizontal slide rod, a vertical slide rod, a telescopic cylinder and a motor. A fixed block is installed at the output end of the motor, is arranged on the outer portion of a rotation rod in a sleeving manner and is in sliding fit with the rotation rod. One end of the rotation rod is hinged to a vertical slide sleeve through a hinge shaft. The vision test device has the beneficial effects that while a vision test is conducted, the defective products can be automatically and efficiently removed according to the generated judgment result, the manual removal work does not need to be conducted by people,and the detection efficiency is greatly improved.

Description

Technical field [0001] The invention relates to a mobile phone LOGO detection mechanism, in particular to a visual test device. Background technique [0002] Traditional mobile phones need to detect the graphic style, graphic size, and graphic color processing of the LOGO. Generally, manual detection is used directly. Manual detection has the following shortcomings: low detection efficiency; high cost of detection; unstable detection results. There are man-made uncertain factors; there are situations where staff misplaced defective products into the good product area. [0003] To this end, Chinese utility model patent CN206235580U discloses a visual testing instrument, which includes a frame, a fixture fixedly mounted on the frame and used for mounting a workpiece, a tester set above the fixture and fixedly mounted on the frame, An alarm device fixedly installed on the frame and electrically connected to the tester and a locking device arranged beside the fixture and used for lock...

Problems solved by technology

[0002] Traditional mobile phones need to detect the graphic style, graphic size and graphic color processing of LOGO. Generally, manual detection is used for direct detection. Manual detection has the following disadvantages: low detection efficiency; high cost of detection; unstable detection results, There are artificial uncertain factors; there are situations where the staff misplaces defective products into the good product area

[0003] For this reason, Chinese utility model patent CN206235580U discloses a kind of visual testing instrument, and it comprises frame, is fixedly installed on the frame and is used for the fixture of mounting workpiece, is located at above the fixture and is fixedly installed on the tester on the frame, An alarm device fixedly installed on the frame and electrically connected to the tester and a locking device arranged next to the fixture and used to lock unqualified workpieces in the fixture (2); the locking device is electrically connected to the tester; it has a structure It is simple, easy to use, high work efficiency, low cost, stable detection quality, and avoids human factors to reduce the detection effect. However, after the detection result is output, it can only issue an alarm, and cannot automatically remove defective products. It also needs to be manually removed. , low degree of automation
