Description

Technical Field

[0001] The present invention relates to the field of chip processing, and in particular to a coiled chip detection and cutting device, and a control method for the coiled chip detection and cutting device. Background Art

[0002] In the current chip manufacturing industry, the process of detecting and separating defective reel chips is usually done manually. After loading and unloading the reel chips, workers inspect each chip piece by piece. If a defective chip is found, it needs to be cut manually with a blade, and then the reel needs to be manually rewound after inspection.

[0003] The existing method of processing rolled chips is slow and has low detection efficiency. There is also the possibility of misjudgment due to human factors. Manual rewinding will cause the reeled material to be uneven. In addition, the use of blades to cut defective products has low output and efficiency, product differences, and great safety hazards. Summary of the Invention

[0004] The purpose of the present invention is to provide a coil chip detection and cutting device that solves the problems of low coil chip detection efficiency and poor quality of manually cut products. Another purpose of the present invention is to provide a control method for the coil chip detection and cutting device that can improve detection efficiency and quickly cut defective chips.

[0011] Preferably, the cutting mechanism includes a laser fixed on a table seat by a bracket and a refraction mechanism located at the light-emitting portion of the laser. The cutting laser emitted by the laser is refracted by a galvanometer, a field lens, and a beam expander built into the refraction mechanism and then passes through the processing hole to cut the chip film segment judged as defective by the control module.

[0012] Preferably, the control module includes a PLC controller mounted on a table seat via a bracket, the coil chip detection sensor and the detection mechanism are control-connected to the PLC controller, and the PLC controller is control-connected to a stepping motor, a dust collecting device, and a cutting mechanism respectively.
