[0003] The above method has many disadvantages: the inspection needs to be cut in advance, and once a row of LEDs is unqualified, the entire product will be scrapped, which is a serious waste; the inspectors need to use a microscope for about 8 hours a day, which affects the vision of the personnel and can easily cause damage to the human eye. Fatigue; manual detection is slow, low detection efficiency, and requires a large number of detection personnel; poor reliability, high probability of missed detection, and easy to cause quality customer complaints

The invention discloses an LED appearance detection machine which comprises a feeding unit for driving an LED semi-finished product material belt to move, four CCD detection units for detecting the quality of LED semi-finished products, a cutting unit arranged in back of the feeding unit along the feeding direction of the feeding unit and used for cutting the LED semi-finished product material belt, and a controller for controlling the feeding unit, the detection units and the cutting unit to work in a cooperative manner, wherein the CCD detection units are arranged along the feeding direction of the feeding unit and comprises cameras arranged above the feeding unit; the feeding units, the cutting unit and the cameras are respectively electrically connected with the controller. The LED appearance detection machine has the advantages that products are saved, waste is reduced, the detection speed is high, the accuracy and the reliability are high, the labor cost is saved, and the like.
Description
technical field [0001] The invention relates to an LED appearance inspection machine for inspecting the quality of LED semi-finished products. Background technique [0002] The existing inspection method for the appearance of LED semi-finished products is to first cut the LED semi-finished material tape into pieces according to the specified length, each piece contains several columns, and then manually use a microscope to visually inspect each piece of product to detect whether there are LED chips inside each column. Dirt, scratches, foreign objects, and whether there are missing materials, black spots, dirt, excess materials, scratches, and foreign objects on the semi-finished LED plastic. If there are no above-mentioned defects, the product is qualified, otherwise only one of the products is required. If there are any defects, the product will be scrapped in its entirety. [0003] The above method has many disadvantages: the inspection needs to be cut in advance, and onc...
