With test equipment be connected insert row by winding displacement first when being tested by this tool, and pcb board then is placed in into institute State on product mounting table, and positioned by positioning head, cause that testing cassete is moved down by drive mechanism afterwards, until visiting Pin is contacted with the COB chips on pcb board, starts test equipment, and testing cassete is lifted after test completion, removes pcb board.Due to this The size of tool testing cassete is adapted with PCB, and probe can cover each COB chip, it is achieved thereby that once testing whole COB chips on pcb board, and without being detected to the COB chips on every pcb board to be measured in turn, human cost is reduced, Efficiency is improve, and in the absence of the phenomenon of missing inspection, the accuracy of test result is high.

Further, the drive mechanism includes handle, articulated elements, fixed seat and sliding bar, the fixed seat and institute State installing plate to be fixedly connected, the top of the fixed seat is hinged with the handle, the handle also by the articulated elements with it is described The upper end of sliding bar is hinged, and the lower end of the sliding bar is fixedly connected with the top of the testing cassete, and the sliding bar is also spacing In the fairlead of fixed seat bottom.

Using said structure, in the case of very low cost of implementation, with good operability and operating efficiency, and behaviour Make uncomplicated, help to be widely popularized in industry.

Further, the fixed seat is in C character form structures, and C character form structures middle part is fixedly connected with the installing plate, institute State handle and be divided into the two ends of the C character form structures with fairlead.

Further, via is offered on the installing plate, the lower end of the testing cassete is extended into the right in the via, And be connected with the fixed plate.

By said structure simultaneously, it is ensured that testing cassete can be moved up and down with insert row, it is to avoid broken because differential is moved Wire between probe and insert row.

Further, guide rail is further fixed on the right side of the installing plate, the fixed plate can glide along on the guide rail It is dynamic.By guide rail so that fixed plate is more stablized with insert row when moving up and down, and thereby helps to ensure that measuring accuracy.

Further, guide post is additionally provided with the right side of the installing plate, the bottom of the testing cassete is arranged in the guiding In bar.By guide post so that testing cassete is more stablized with insert row when moving up and down, and thereby helps to ensure that measuring accuracy.

Further, there is more preferable structural strength in order to ensure this tool, is also set between the installing plate and base plate There is reinforcing plate, and the reinforcing plate is located at the right side of the installing plate.

Remarkable result of the present utility model is：Simple structure, it is easy to operate, realize and once test on whole pcb board COB chips, and the COB chips on every pcb board to be measured need to be detected in turn without to traditional sensing techniques, reduce people Power cost, improves efficiency, and in the absence of the phenomenon of missing inspection, the accuracy of test result is high.
