Detailed Description
The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.
The specific embodiment is as follows: referring to fig. 1-5, a circuit board testing device includes a workbench 2, a detecting board 3 is disposed on the workbench 2, a plurality of probes 31 in horizontal direction are disposed on the detecting board 3, the probes 31 are communicated with an internal circuit of the workbench 2, a guide rail 5 with an extending direction parallel to the extending direction of the probes 31 is further disposed on the workbench 2, a moving table 4 is slidably connected on the guide rail 5, the moving table 4 is driven by a driving mechanism to move along the guide rail 5, a first concave table 42 for placing a circuit board 1 to be tested is disposed on the moving table 4, positioning columns 43 corresponding to the mounting holes 11 are disposed in the first concave table 42, a pressing mechanism 41 is disposed at two ends of the moving table 4, and a guiding mechanism 7 for releasing the circuit board 1 to be tested is disposed at a position outside the pressing mechanism 41 on the workbench 2. When the terminals 12 on the circuit board 1 to be tested are in contact with the probes 31, the pressing mechanism 41 has pressed the circuit board 1 to be tested into the first concave table 42 so that it is not easy to move upward.
Specifically, the pressing mechanism 41 includes a rotating column 412, a pin shaft 417 is disposed in the middle of the rotating column 412, an ear plate 411 is disposed at a position on two sides of the rotating column 412 on the workbench 2, the pin shaft 417 is rotationally connected with the ear plate 411, a pressing rod 413 is disposed at one end of the rotating column 412, which is close to the first concave table 42, a rubber head is disposed at the lower end of the pressing rod 413, a baffle 415 is further disposed on the workbench 2, the baffle 415 is located at one side of the pin shaft 417, which is close to the first concave table 42, a torsion spring 416 is sleeved on the pin shaft 417, and two torsion arms of the torsion spring 416 are respectively contacted with the baffle 415 and one end, which is far from the first concave table 42, of the rotating column 412 so that the pressing rod 413 can press the circuit board 1 to be tested. The pressing mechanism 41 can press the circuit board 1 to be tested without contacting the guide mechanism 7.
Specifically, a guide plate 71 is disposed on one side of the guide mechanism 7 near the detection plate 3, the bottom surface of the guide plate 71 is an inclined surface, and one end of the inclined surface near the detection plate 3 is higher than one end of the inclined surface far away from the detection plate 3. Referring to fig. 1, when the mobile station 4 moves rightward, after a certain distance, one end of the rotating post 412 away from the pressing rod 413 contacts the inclined plane, and as the mobile station 4 continues to move, one end of the rotating post 412 provided with the pressing rod 413 is lifted upward, so that the circuit board 1 to be tested is released.
Further, a roller 414 is disposed at an end of the rotating post 412 away from the pressing rod 413, and the roller 414 is used for contacting with the inclined plane, so as to reduce the friction between the rotating post 412 and the inclined plane.
Further, two sides of the first concave stage 42 are provided with second concave stages 44, and the depth of the second concave stages 44 is greater than that of the first concave stage 42.
