Visual inspection device and judgment method for identifying positive direction of LED support

Abstract

The invention relates to a visual inspection device and judgment method for identifying a positive direction of an LED support. The visual inspection device comprises a backlight surface light source, a GIGE port industrial camera, a telecentric lens and a limiting device, wherein the backlight surface light source is arranged on an LED foot cutter platform and emitting light from the back of the LED support; the GIGE port industrial camera is arranged on the LED foot cutter platform and is opposite to the backlight surface light source; the telecentric lens is arranged on the GIGE port industrial camera and used for collecting light parallel to the direction of the lens; and the limiting device is arranged on the LED foot cutter platform and used for limiting movement of the LED support. The GIGE port industrial camera, the telecentric lens and the limiting device are connected with a controller. By adoption of the design, the problem that the LED support wrong in direction enters a foot cutting mechanism of a foot cutter is solved thoroughly, and the problem that an LED bead direction is wrong is solved. Besides, the labor cost is reduced, and detection efficiency and detection results are improved.

Description

technical field [0001] The invention relates to a visual detection device and a judgment method, in particular to a visual detection device and a judgment method for identifying the positive direction of an LED bracket. Background technique [0002] The leg cutting machine is an automatic equipment used in the field of LED packaging. It is used to cut the strips of LED lamp beads into single scattered lamps, and the current of the lamp beads is represented by the asymmetric shape of the colloid and the length of the lamp beads. Direction, if the LED lamp beads are put into the cutting machine in the wrong direction, the colloid and length of the lamp beads after the cutting machine will be in the wrong direction, resulting in waste products, and this waste product is mixed with a large number of single scattered lights. In the lamp, it is like a rat droppings, breaking a pot of porridge, causing a large number of products to be scrapped, and the LED lamp beads are relatively...

[0002] The leg cutting machine is an automatic equipment used in the field of LED packaging. It is used to cut the strips of LED lamp beads into single scattered lamps, and the current of the lamp beads is represented by the asymmetric shape of the colloid and the length of the lamp beads. Direction, if the LED lamp beads are put into the cutting machine in the wrong direction, the colloid and length of the lamp beads after the cutting machine will be in the wrong direction, resulting in waste products, and this waste product is mixed with a large number of single scattered lights. In the lamp, it is like a rat droppings, breaking a pot of porridge, causing a large number of products to be scrapped, and the LED lamp beads are relatively small, so manual inspection is very difficult. If you want to mix LEDs in the wrong direction It takes a lot of manpower to select the lamp beads, which causes a lot of waste, and the detection effect is not ideal, and it is easy to miss detection.
