Description

technical field [0001] The invention relates to a batch detection device and method for cluster variable-diameter deep holes. Background technique [0002] At present, the cluster variable diameter deep well plate is an important component in the industry, especially in the chemical industry. As an indispensable precision part in industry, its function is to extrude polymer material bundles with a certain thickness and fine texture through the micro-holes on the cluster variable-diameter deep-hole plate through the precisely metered polymer melt or solution. Therefore, the development of cluster variable-diameter deep-well plates is helpful to promote the development of new polymer materials. The manufacturing precision of the cluster variable-diameter deep-hole plate determines the quality of the polymer material molding, and the shape of the micropores of the cluster variable-diameter deep-well plate determines the cross-sectional shape of the polymer material, which in t...

Problems solved by technology

Among them, the bottom irradiation method of the strong light source can only observe whether the holes on the entire board surface are transparent and whether there are holes blocked. It is easy to miss inspection, and it is impossible to find small dirt in the holes, and it is impossible to quantify the data of cluster variable-diameter deep holes.

Although detection under a microscope can enlarge the pores and observe the tiny dirt in the pores, for tens of thousands of micropores, and the distance between the holes is only less than 100 μm, missed detection is also very easy to occur, even if It is extremely difficult to find out the dirt in a certain hole on the cluster variable-diameter deep-well plate, and the microscope is manually detected and cannot be replaced by a machine. Manual detection is labor-intensive and the detection accuracy is low

[0004] In the prior art in this field, usually for the cluster variable diameter deep hole in the cluster variable diameter deep hole plate, whether it is a guide hole, a micro hole or a transition hole, Whether it is manual inspection or machine inspection, it can only detect one by one cluster variable diameter deep holes, but the cluster variable diameter deep hole number on the cluster variable diameter deep hole plate is at least about 50, and the maximum can reach 12,000-98,000 Only, and the pore diameter is between 10-50 μm, it will take a lot of time, manpower, and material costs to detect one by one, and it is difficult to guarantee the detection accuracy; at the same time, it is very easy to miss and repeat the detection one by one. In some cases, the clearly discarded cluster variable-diameter deep-well plates will be put into use by mistake, causing serious production accidents

At present, in the entire industry, a complete batch detection standard and mature algorithm have not yet been formed
