A nozzle detection method, system, device and storage medium

Abstract

The embodiment of the present invention discloses a suction nozzle detection method, which includes the steps of: obtaining the basic parameters of the suction nozzle to be tested; extracting the gas in the suction nozzle to be in the suction state, and obtaining the suction index; Test multiple detection data with the same nozzle model; decrypt the multiple detection data according to the pre-acquired public key of each upload node, and filter out the detection data that the plaintext nozzle model is inconsistent with the encrypted nozzle model, Obtain a credible detection data set; according to the preset use record and production date similarity requirements, filter the detection data that meets the requirements to obtain a historical detection data set; obtain the detection result based on the suction index and the detection data in the historical detection data set. The embodiment of the present invention also provides a suction nozzle detection system, equipment and storage medium, which can effectively improve the detection efficiency of the suction nozzle while taking into account the detection accuracy, and realize fast and accurate detection of the suction nozzle.

Description

technical field [0001] The invention relates to the technical field of detection of suction nozzles of chip mounters, in particular to a method, system, equipment and storage medium for detection of suction nozzles. Background technique [0002] In the production process of the chip, the placement machine of the chip production line absorbs the components through the suction nozzle and then mounts them on the printed circuit board. The working status of the suction nozzle directly affects the placement quality. Since the front end of the commonly used suction nozzle is small, generally within 0.6*0.6mm, and the suction nozzle is a part that directly contacts the components, it is prone to wear and tear during the contact with the components, which affects the suction of the suction nozzle. The use of problematic nozzles for production may cause material throwing, flying materials, etc., which directly affect the placement quality, so the inspection of the placement machine n...

Problems solved by technology

Since the front end of the commonly used suction nozzle is small, generally within 0.6*0.6mm, and the suction nozzle is a part that directly contacts the components, it is prone to wear and tear during the contact with the components, resulting in the suction of the suction nozzle being affected

The use of problematic nozzles for production may cause material throwing, flying materials, etc., which directly affect the placement quality, so the inspection of the placement machine nozzles is particularly critical

[0003] The inventor found in the process of implementing the present invention that due to the small front end of the suction nozzle, in the existing detection method of the suction nozzle, in order to obtain a more reliable detection result, the methods generally adopted include: (1) improving the accuracy of the detection equipment, However, the cost of equipment replacement and inspection is high; (2) Multiple inspections are performed on the suction nozzle, so as to reduce the detection error by analyzing multiple sets of data, but it will cause more unnecessary wear and tear on the suction nozzle and prolong the detection time. The time required, the detection efficiency is low
