Description

[0002] 3C products are widely used in various aspects of production and life, and various types of 3C parts are involved in 3C products. In 3C part processing and 3C product assembly, 3C parts need to be moved in each workstation during processing and production. In order to improve production speed, mechanical grabbing or vacuum suction is usually used instead of manual material moving. However, for large-size sheet materials (such as keyboard glue), the following problems exist: first, mechanical grabbing can easily damage the sheet material, and vacuum suction can easily over-press the sheet material, causing part damage and low product precision, and the yield is reduced. Second, mechanical grabbing is usually single-point grabbing, and 3C sheet material can easily shake in the moving path. Similarly, when the local adsorption point of multi-point vacuum suction is poorly adsorbed, 3C sheet material can also easily shake, so the stability during moving is poor, the position precision during discharging is poor, and the speed is slow, making it difficult to mass-produce continuously.
