In the description of the present utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection", and "setting" should be understood in a broad sense, for example, it can be fixed connection, setting, or It is detachably connected, set, or integrally connected, set. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present utility model in specific situations.

As shown in Figure 1, a kind of circuit board positioning test module of the present utility model comprises rectangular housing 10, tested circuit board 2, glass plate 1, observation board 11 and needle gauge 3, and described housing 10 upper and lower ends Both are open, and an LED panel light 4 is fixedly installed on the opening of the upper end of the housing 10 through a hinge. Both sides of 7 are open, and a slider 8 is slidably installed in the chute 7, and an "L"-shaped support rod 6 is fixedly installed on the end surface of the slider 8 facing the inside of the housing 10, and the upper end of the support rod 6 is fixedly installed. A "U"-shaped card slot 5, the opposite surface and both sides of the card slot 5 are open, the tested circuit board 2 is arranged between the two card slots 5, and the left side of the tested circuit board 2 is inserted into the left side In the card slot 5, insert the right side into the card slot 5 on the right side.

The glass plate 1 is fixedly installed inside the housing 10, the glass plate 1 and the tested circuit board 2 are arranged in parallel, the needle gauge 3 is fixedly installed on the upper end of the glass plate 1, and there are multiple needle gauges 3, the number of the needle gauge 3 is the same as that of the tested circuit board 2. The number of welding holes on the test circuit board 2 is the same, and the arrangement structure is also the same. The upper ends of the needle gauge 3 pass through the corresponding welding holes, and the diameter of the needle gauge 3 is the same as the diameter of the inside of the welding hole.

A handle 9 is fixedly installed on one end surface of the slider 8 towards the outside; the observation plate 11 is arranged at the lower end of the housing 10, and there is a certain distance between the two, and more than one wire is passed between the observation plate 11 and the housing 10 The straight rod is fixedly connected, and the color on the surface of the observation plate 11 is black.

Working principle: This device needs to be carried out in a relatively dark environment. When using it, first turn on the LED panel light, and then move the slider upward through the handle. The movement of the slider drives the card slot until the two card slots are moved to the outside world. , at this time, insert the tested circuit board into the card slot along the opening on the side of the card slot, position the tested circuit board, and then move the slider down by the handle, the movement of the slider drives the card slot and the card slot The tested circuit board until the needle gauges pass through the welding holes one by one. At this time, cover the LED panel light and turn on the LED panel light. The light generated by the LED panel light will directly shine on the tested circuit board. Since the pin gauge is made by installing the aperture of the soldering hole of the tested circuit board, if the aperture size of the soldering hole is standard, then the light will not pass through the gap between the soldering hole and the pin gauge, otherwise, the soldering hole If the aperture is too large, the light will pass through the gap between the soldering hole and the pin gauge, and the passing light will directly shine on the observation board, so that it can quickly know whether the aperture of the tested circuit board is qualified.

The beneficial effects of the utility model are: the utility model is simple in structure, easy to use, and can check all apertures on the circuit board at one time, greatly increasing the efficiency of detection and increasing the production speed.
