Problems solved by technology

The disadvantages are: visual deviation and the influence of natural light source, the pass rate of the actual machine of the suction nozzle after visual confirmation is about 70%, and there is often a very high material loss rate during the production of the actual machine of the confirmed suction nozzle
New suction nozzles need to be replaced for reproduction, while the previous discarded materials can only be disposed of, which virtually improves the finished product

Embodiment 1

[0022] This embodiment provides a method for cleaning and detecting suction nozzles, which specifically includes: an automatic rotary positioning and placing platform, a light source image acquisition and imaging device, a terminal imaging display device, an area detection and determination device, a defective prompting device, and a green light source device; the light source image acquisition The imaging device includes a vertically fixed continuous zoom single-lens microscope and a 2D camera with amplifying signal function; the area detection and determination device includes: PLC and a photosensitive analysis sensor; the continuous zoom single-lens microscope is vertically fixed, the The lens and the suction nozzle are placed vertically; the automatic rotation positioning platform is provided with a suction nozzle placement hole, and the green light source device is installed below each suction nozzle placement hole; the terminal imaging display device is respectively connec...

Embodiment 2

[0024] This embodiment describes in detail the various components involved in the above embodiments:

[0025] Multiple suction nozzle placement holes are set on the automatic rotation positioning table 1, and multiple suction nozzles can be judged at one time, and the suction nozzles are manually placed or taken out of the suction nozzle placement holes, and other actions are completed automatically. The role of rotation It is to complete the movement from a suction nozzle position to a certain position. The automatic rotation positioning placing table 1 is driven by a stepping motor, and the rotation position is completed by a limit sensor. The green light source device 6 adopts a 12V green LED, and a green LED is fixed below each suction nozzle placement hole.

[0026] The area detection and judgment device 4 is composed of PLC plus a photosensitive analysis sensor. The signal of the photosensitive analysis sensor is set to a pass rate of 98%. If it is lower than the set va...

Abstract

The invention relates to a suction nozzle sweeping detection method. The suction nozzle sweeping detection method specifically comprises the following steps: putting a to-be-detected suction nozzle in a suction nozzle placing hole site on an automatic rotary positioning placing table, wherein the automatic rotary positioning placing table is driven by a stepping motor to rotate and a limiting sensor determines the rotating position, so that each suction nozzle placing hole site is located above a corresponding green light source device; after igniting the green light source, directly penetrating at the bottom end of the suction nozzle and floating on the surface of the suction nozzle; directly reading a light source obtained by a microscope by a 2D camera, and representing the light source on a display screen in a terminal imaging display device after amplifying a certain multiple; and feeding image information to a light perception analyzing inductor which divides good products and rejected products according to the set threshold value of the area of the suction nozzle. According to the method provided by the invention, not only can the detecting quality be improved and also the time of visual confirmation can be shortened. Moreover, the loss of a material caused by poor suction nozzle is reduced, and the cost in a manufacturing process is effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of cleaning detection, and in particular relates to a method for cleaning and detection of suction nozzles. Background technique [0002] Improving product quality and reducing product manufacturing costs are the goals that various enterprises are constantly pursuing, and they are also the foundation for realizing the development of enterprises.
