If it is set as an adjustable slot, the back and forth operation adjustment will affect the work efficiency, and there are certain limitations in use. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-size tooling for PCB board testing, so as to solve the problem that the existing PCB board slot specifications proposed in the above background technology are all fixed and the operation is single, which cannot be applied to the placement and detection of PCB boards of different specifications, and if it is set as an adjustable slot, the back and forth operation adjustment will affect the work efficiency and there are certain limitations in use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-size tooling for PCB board testing, comprising a mounting seat, a plurality of mounting bolts are passed through the mounting seat, a servo motor is fixedly mounted on the inner wall of the mounting seat, a disc is fixedly mounted on the end of the output shaft of the servo motor, a plurality of mounting plates are mounted on the disc in a ring array, a tooling slot is mounted on the surface of the mounting plate, and the specifications and sizes of the plurality of tooling slots are different, a sliding frame is slidably mounted on the outside of the tooling slot, a first connecting plate is fixedly mounted on both sides of the upper surface of the sliding frame, a support plate is fixedly mounted on the top of the first connecting plate, a second connecting plate is slidably mounted on the side of the support plate, blocking bars are fixedly mounted on both ends of the second connecting plate, the end surface of the blocking bar has an inclined surface and the inclined surface is arranged upward, a receiving groove is opened on the inner wall of the tooling slot, and a top plate is movably arranged in the receiving groove.

[0006] By adopting the above scheme, multiple tooling slots are provided for use with servo motors. The specifications and sizes of the multiple tooling slots are different. Therefore, when testing PCB board products of different specifications, it is only necessary to switch the positions of the tooling slots through the servo motor, thereby avoiding the inconvenience of operation and the problem of affecting efficiency of adjustable tooling slots. The operation and adjustment are convenient. By providing a sliding frame for use with a blocking bar, the sliding frame can move up and down and cooperate with the blocking bar to achieve the longitudinal limiting effect of the PCB board, thereby ensuring the stability of the PCB board without shaking during the test. In addition, when used with a top plate, the PCB board can be quickly ejected after the test is completed, thereby improving the convenience of operation.

[0007] In the above solution, it should be noted that the servo motor is electrically connected to the external power supply.

[0008] As a preferred embodiment, a plurality of connecting plates are fixedly mounted on the lower surface of the disc, an arc-shaped slider is fixedly mounted on the side of the connecting plate, an annular slide rail is welded on the outer surface of the mounting seat, and the arc-shaped slider is slidably mounted on the inner wall of the annular slide rail.

[0009] By adopting the above scheme, when the servo motor drives the disc to rotate, the disc drives the connecting piece to rotate, and the connecting piece drives the arc-shaped slider to slide in the arc-shaped slide rail, thereby supporting the rotation of the disc, making the disc more stable in rotation and less prone to shaking.

[0010] As a preferred embodiment, a plurality of trapezoidal slide bars are fixedly mounted on the side of the tooling slot, a plurality of trapezoidal slide grooves are opened on the inner wall of the sliding frame, and the trapezoidal slide bars and the trapezoidal slide grooves are used in combination.

[0013] By adopting the above scheme, the locking rod is used in conjunction with the first spring. When the locking rod is disengaged from the locking slot, the first spring is deformed. At this time, the sliding frame can slide up and down. After sliding to the desired position, the elasticity of the first spring is used to drive the locking rod to quickly return to the lock slot, thereby improving the convenience of operation.

[0014] As a preferred embodiment, a plurality of guide rods are fixedly mounted on the side of the support plate, the guide rods are slidably mounted on the second connecting plate and a limit plate is fixedly mounted on the end of the guide rods, and a second spring is fixedly mounted between the limit plate and the second connecting plate.

[0015] By adopting the above solution, the setting of the guide rod can support and guide the movement of the second connecting plate and the blocking bar, thereby improving the movement stability, and the elasticity of the second spring can achieve a rapid reset effect of the blocking bar.

[0016] As a preferred embodiment, a sliding rod is fixedly installed on the lower surface of the top plate, and the sliding rod slides through the tooling slot and the mounting plate and is fixedly installed with a limit plate, and a third spring is fixedly installed between the limit plate and the mounting plate.

[0017] With the above solution, the top plate is used in conjunction with the sliding rod and the third spring. When the blocking bar no longer blocks the PCB, the elasticity of the third spring drives the top plate to move upward, thereby ejecting the PCB.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The multi-size tooling for PCB board testing is used by setting multiple tooling slots and cooperating with a servo motor. The specifications and sizes of the multiple tooling slots are different. Therefore, when testing PCB board products of different specifications, it is only necessary to switch the positions of the tooling slots through the servo motor, thereby avoiding the inconvenience of operation and the problem of affecting efficiency of the adjustable tooling slots, and the operation and adjustment are convenient;

[0020] The multi-size tooling for PCB board testing is used by setting a sliding frame in conjunction with a blocking bar. The sliding frame can move up and down and be used in conjunction with the blocking bar to achieve a longitudinal limiting effect on the PCB board, ensuring that the PCB board is stable and does not shake during the test. When used in conjunction with a top plate, the PCB board can be quickly ejected after the test is completed, thereby improving the convenience of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] A plurality of trapezoidal slide bars 16 are fixedly installed on the side of the tooling slot 6, and a plurality of trapezoidal slide grooves are opened on the inner wall of the sliding frame 7. The trapezoidal slide bars 16 and the trapezoidal slide grooves are used in combination, and the trapezoidal slide bars 16 are used in combination with the trapezoidal slide grooves, so that the sliding frame 7 is not easy to shake or loosen when sliding up and down to adjust the position.
