Precision vacuum nozzle mechanism

Abstract

The invention discloses and provides a precision vacuum nozzle mechanism which is simple in structure, safe and reliable, capable of replacing a nozzle conveniently and precise and stable to mount. The precision vacuum nozzle mechanism comprises an adapting assembly for being connected with an external vacuum system, a nozzle pipe body and a nozzle sleeve. The adapting assembly comprises an adapting seat and a directional boss arranged on the adapting seat. The directional boss is used for guide positioning during mounting. Multiple suction holes are formed in the nozzle pipe body. The size of the suction holes and the distance between the suction holes are all matched with products. The nozzle sleeve is used for connecting the suction pipe body with the adapting seat. A buckle connecting module is arranged between the nozzle sleeve and the adapting seat. The precision vacuum nozzle mechanism is used for the technical field of vacuum nozzles.

Description

technical field [0001] The invention relates to a precise vacuum suction nozzle mechanism. Background technique [0002] At present, the reliability test of consumer electronics products has become the key to ensure their performance and life. The traditional testing method is to pick and place products manually, which is not only time-consuming and laborious, but also increases the danger for the operator. Test automation is a major trend in future development. In the field of automated testing, a vacuum system is usually required to complete the pick-and-place of electronic products or devices under test. [0003] The mechanism for generating vacuum suction in the prior art is usually an integrated vacuum nozzle, which has the following problems in the high-precision testing industry: 1. The vacuum nozzle is usually installed on the module of the machine through threads , because the vacuum nozzle is a moving mechanism, it is a consumable product, and it is difficult to ...

Problems solved by technology

[0003] The mechanism for generating vacuum suction in the prior art is usually an integrated vacuum nozzle, which has the following problems in the high-precision testing industry: 1. The vacuum nozzle is usually installed on the module of the machine through threads , because the vacuum nozzle is a moving mechanism, it is a consumable product, and it is difficult to replace this type of nozzle during equipment maintenance and overhaul; 2. The contact between this type of nozzle and the product is hard contact, which is easy to damage the sucked product. Reduce the test yield of products; 3. Suction nozzles mostly use shaft-hole fit, and only through threaded connection, it is difficult to guarantee the relative position and installation accuracy of suction nozzles, adapters and products
