Description

Technical Field

[0001] The utility model relates to the technical field of rubber-coated suction nozzles, in particular to an anti-static rubber-coated suction nozzle. Background Art

[0002] In the field of non-standard automation, it is well known that different structures of suction nozzles are used to pick up workpieces. In the process of researching and implementing the suction of workpieces, the inventors of the utility model found that the suction nozzles in the prior art have at least the following problems.

[0003] Film products are very thin and easily deformed when subjected to uneven force. When sucking film products, the existing suction nozzle has a single suction hole that is very likely to have uneven force, causing the film products to deform. This can affect subsequent operations and reduce work efficiency. At the same time, the protection of the interior of the nozzle is poor, which can easily cause damage to the interior of the nozzle and affect the adsorption efficiency. Utility Model Content
