Printing machine automatic adjusting system and method based on UVW platform and machine vision

Abstract

The invention relates to a printing machine automatic adjusting system based on a UVW platform and machine vision, the printing machine automatic adjusting system comprises an automatic alignment platform, and a printing head and a vision monitoring device which are connected with the automatic alignment platform, the printing head is embedded in the upper end face of the automatic alignment platform, and the vision monitoring device is connected with the outer side face of the automatic alignment platform through an adjusting mechanism. The using method comprises the two steps of equipment assembling and machining operation. On one hand, various automatic alignment platforms on the market can be effectively operated in a matched mode according to use requirements; and on the other hand, human eye judgment can be replaced by industrial camera photographing, and the current data volume needing to be translated and rotated is accurately calculated, so that the working precision of machining operation is greatly improved, meanwhile, the difficulty of equipment production learning and operation is effectively reduced, and the production rejection rate is reduced.

Description

technical field [0001] The invention relates to a printing machine automatic adjustment system and method based on a UVW platform and machine vision, belonging to the technical field of machining. Background technique [0002] In the production process of chip capacitors and resistors, the relative position of the printed pattern and the substrate stripping line is required to be very accurate. Due to the variety of product types, many printing processes, and complicated printing processes, the current market relies on human eyes to observe the printing position offset. Adjust the printing accuracy by manually twisting the position of the adjustment lever. This method relies heavily on human experience, the adjustment process is slow and accurate, the training time for personnel is long, and it is easy to lose the current normal products. To solve this problem, a variety of auxiliary processing equipment based on the automatic alignment platform has been developed. , such a...

This method relies heavily on human experience, the adjustment process is slow and accurate, the training time for personnel is long, and it is easy to lose the current normal products. To solve this problem, a variety of auxiliary processing equipment based on the automatic alignment platform has been developed. , such as "a two-axis automatic alignment platform" with the patent application number "201820110666.6", "six-axis automatic alignment platform" with the patent application number "201620151808.4" and "a "Automatic alignment platform" and other equipment can meet the needs of use to a certain extent, but the current equipment often has a fixed structure, which can only meet the needs of specific environments and fields, and the flexibility and versatility of use are both It is relatively poor, and at the same time, it is often necessary to use staff observation to detect the machining state, so it is very easy to affect the operation accuracy of the equipment due to staff observation errors, and it is still difficult to effectively meet the requirements of high-precision equipment such as chip capacitors.
