Description

Horn seat direction inspection fixture

Technical field

The utility model relates to the technical field of detection equipment, and in particular to a horn seat direction inspection fixture.

Background technique

At present, in the production process of LED display screens, electronic components such as the horn base 400 are generally affixed to the back of the PCB board through a placement machine. The structure of the horn base 400 can be seen in FIG. 1 , which includes a body 410 and a plurality of pins provided on the body 410 , and a groove 420 is also provided on one side of the body 410 . Among them, the specific steps of attaching the horn holders 400 to the back of the PCB board are: first, manually place multiple horn holders 400 on the material tray, and then place the material tray with the horn holders 400 on the placement machine. Mount the horn base 400 on the PCB board. In the process of manually placing the horn holder 400, the horn holder 400 may be placed in the material tray in reverse due to factors such as careless operation. If this situation is not discovered in the subsequent process, the subsequent placement machine will place the horn holder 400. If applied backwards, the groove 420 will be reversed. When subsequent products are used, due to the reverse direction of the horn base 400, the PCB board may be burned due to reverse signal connection, resulting in the product becoming unusable and reducing the production throughput rate.
