Description

Quick replacement method and device for EPD product inspection program of electronic paper Technical Field The invention relates to the technical field of EPD product inspection, in particular to a method and a device for quickly replacing an EPD product inspection program of electronic paper. Background In the production manufacturing process of the electronic paper EPD product, product inspection is a key link for guaranteeing product quality, and the test jig has the characteristics of high pertinence, convenience in operation and the like, and is still a core structure widely used in the inspection process of the electronic paper EPD product, and an integrated structural design is adopted, so that an inspection program is fixedly bound with a test unit of the jig. It should be explained that when the EPD products of electronic paper with different models and different specifications are to be inspected, the test units of the test fixture must be re-burned and replaced with the inspection program, and because the program burning requires a certain time, the inspection personnel need to wait in line, so that the inspection preparation time is greatly prolonged, the overall production inspection efficiency is seriously affected, and the high-efficiency inspection requirement of batch production is difficult to meet. Secondly, in the integrally designed test fixture, if the test unit and the fixture main body are not detachable, the whole test fixture is required to be shut down, disassembled and maintained if the test unit fails or is damaged, and any product inspection work cannot be carried out during maintenance, so that the utilization rate of the test fixture is low, and the production and manufacturing cost is indirectly increased; In addition, the program replacement operation of the traditional test fixture is complex, the requirement on the professional skill of the inspector is high, the service life of the test unit can be reduced due to frequent program burning operation, the stability and the continuity of the inspection work are further affected, and the invention provides a solution for the problems. Disclosure of Invention The invention aims to provide a quick replacement method and device for an inspection program of an electronic paper EPD product, and aims to realize quick switching of the inspection program, reduce inspection preparation time, improve the utilization rate of a test fixture and reduce production inspection cost. The invention can be realized by the following technical scheme that the quick replacement method of the EPD product inspection program of the electronic paper adopts a detachable independent test unit group scheme, an inspection frame is built through the combination of a plurality of independent test unit groups, and each independent test unit group can complete the burning preparation of the corresponding inspection program in advance, and the specific operation steps are as follows: Step one, downloading a matched exclusive inspection program for an independent test unit group aiming at the type of an electronic paper EPD product to be inspected; assembling the independent test unit group with the downloaded program to the corresponding installation position of the inspection jig, and completing the quick butt joint of the module and the jig; step three, connecting a power supply and auxiliary detection equipment for the inspection jig, and completing equipment debugging before inspection; And step four, starting a checking flow, and checking the electronic paper EPD product through the assembled testing unit group. In the first step, the multiple independent test unit groups can pre-record the corresponding test programs of the EPD products of the different types of electronic paper respectively to form a program pre-storing module group. And in the second step, the independent test unit group and the inspection jig are assembled in a tool-free convenient disassembly and assembly mode. If a certain independent test unit group fails or the program needs to be updated, the module can be independently disassembled for maintenance or re-burning of the program, and the rest test unit groups can be continuously matched with the test fixture to complete the test work. The invention also provides a quick replacement device for the inspection program of the electronic paper EPD product, which comprises an inspection jig main body and a plurality of independently detachable test unit groups, wherein the inspection jig main body is internally provided with a signal butt joint structure, a power supply structure and an inspection control structure which are matched with the test unit groups, the test unit groups are provided with a program storage structure, a product connection structure and an auxiliary detection butt joint structure, the test unit groups and the inspection jig main body are in a detachable connection mode, a signal transmission process is formed thro
