Description

Technical Field

[0001] The utility model relates to the technical field of circuit testing, in particular to a power circuit testing tooling with a channel parallel connection function. Background Technique

[0002] Circuit testing is a testing method for checking production manufacturing defects and component defects by inspecting the electrical performance and electrical connections of in-line components. It mainly checks individual in-line components and the open and short-circuit conditions of each circuit network. Circuit testing includes various methods, such as in-circuit testing, circuit board testers, integrated circuit testing, and testability design, etc. These methods together constitute a complete system of circuit testing.

[0003] However, when the existing power circuit testing tooling with a channel parallel connection function is in use, the power circuit board with a channel parallel connection function is usually directly placed on the operation rack for testing. However, when the test probe contacts the power circuit board, it will generate pressure on the power circuit board, and the power circuit board will shift. At the same time, the operator needs to manually adjust the position of the test probe, and after the power circuit board test is completed, the operator needs to manually replace the power circuit board, which has a certain impact on the test accuracy and test efficiency of the power circuit board. Therefore, a power circuit testing tooling with a channel parallel connection function is provided. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a power circuit testing tooling with a channel parallel connection function. The utility model solves the problem of low test efficiency of the power circuit board when the existing power circuit testing tooling with a channel parallel connection function is in use by setting a cylinder, an electric telescopic rod, an electric push rod, motor A, motor B, a test probe, a placement rack, a support plate, a lead screw, and a fixing block.

[0005] The technical solution adopted by the utility model to solve its technical problems is a power circuit testing tooling with a channel parallel connection function, including an operation rack. A motor B that drives a drive block to rotate is bolted inside the operation rack. A placement rack for fixing the power circuit board is welded to one side of the drive block. A groove for placing the power circuit board is formed on the surface of the placement rack. An electric push rod that drives a support plate to move is screwed and fixed inside the placement rack. A tester for testing the power circuit board is screwed and fixed inside the operation rack. A wire connected to the test probe is screwed and fixed to one side of the tester. A cylinder that drives a bracket to move is bolted to one side of the operation rack. A motor A that drives a lead screw to rotate is screwed and fixed inside the bracket. A transmission block is threadedly connected to the outside of the lead screw, and an electric telescopic rod is screwed and fixed to the outside of the transmission block. The output end of the electric telescopic rod is screwed and fixed with a fixing block for fixing the test probe.

[0006] By adopting the above technical solution, when testing the power circuit board, first place the power circuit board in the groove opened on the surface of the placement rack. Subsequently, the electric push rod in the placement rack drives the support plate to move, and the support plate contacts the surface of the power circuit board in the groove, thereby facilitating the limiting treatment of the power circuit board placed in the placement rack and preventing the power circuit board from shifting during testing;

[0007] After the power circuit board is fixed in the placement rack, the air cylinder in the operation rack drives the support to move. Then, the motor A in the support drives the lead screw to rotate, the transmission block outside the lead screw drives the electric telescopic rod to move, and the electric telescopic rod drives the test probe on the fixed block to move, so that the test probe contacts the power circuit board in the placement rack, thereby facilitating the testing of different positions of the power circuit board and improving the testing efficiency of the power circuit board;

[0008] When the testing of the power circuit board in the groove of the placement rack is completed, the test probe is separated from the power circuit board. Then, the motor B in the operation rack converts the received electrical energy into mechanical energy, the motor B drives the drive block to rotate, the drive block drives the placement rack to rotate, and the power circuit boards in other grooves in the placement rack move to below the test probe, thereby facilitating the testing of different power circuit boards.

[0009] Specifically, sliders for stabilizing the movement of the support are symmetrically welded to the outside of the support, and sliding grooves for sliding the sliders are symmetrically opened on the inner side of the operation rack.

[0010] By adopting the above technical solution, when the air cylinder drives the support to move, the sliders outside the support slide in the sliding grooves opened in the operation rack, improving the stability of the support moving in the operation rack.

[0011] Specifically, rubber pads for increasing the friction force on the power circuit board are bonded to both the support plate and the inner side of the groove.

[0012] By adopting the above technical solution, when the power circuit board is fixed inside the groove, the rubber pads on the support plate and in the groove increase the friction force on the surface of the power circuit board, improving the stability of the power circuit board fixation.

[0013] Specifically, a limiting groove is opened inside the operation rack, and a circular plate connected to the drive block is slidably connected to the inner side of the limiting groove.

[0014] By adopting the above technical solution, when the motor B drives the drive block to rotate, the circular plate outside the drive block slides in the limiting groove opened in the operation rack, improving the stability of the drive block rotation.

[0015] Specifically, the input ends of the motor A, motor B, air cylinder, electric telescopic rod, and electric push rod are all electrically connected to the power supply end of an external power supply.

[0016] By adopting the above technical solution, by connecting an external power supply, the electrical device operates normally.

[0019] (2) For the power circuit test tooling with channel parallel connection function of the present utility model, after the power circuit board is fixed in the placement rack, the air cylinder in the operation rack drives the support to move. Then, the motor A in the support drives the lead screw to rotate, the transmission block outside the lead screw drives the electric telescopic rod to move, and the electric telescopic rod drives the test probe on the fixed block to move, so that the test probe contacts the power circuit board in the placement rack, thereby facilitating the test treatment of different positions of the power circuit board and improving the test efficiency of the power circuit board.

[0020] (3) For the power circuit test tooling with channel parallel connection function of the present utility model, after the test of the power circuit board in the groove of the placement rack is completed, the test probe is separated from the power circuit board.

[0027] In order to improve the test efficiency of the power circuit board, as an embodiment of the present utility model, as Figure 1 、 Figure 2 and Figure 3 shown, a power circuit test tooling with channel parallel function described in the present utility model includes an operation frame 3. A motor B22 for driving a driving block 19 to rotate is bolted inside the operation frame 3. A placing rack 9 for fixing the power circuit board is welded on one side of the driving block 19. A groove 4 for placing the power circuit board is formed on the surface of the placing rack 9.

[0028] During use, when testing the power circuit board, first place the power circuit board in the groove 4 formed on the surface of the placing rack 9. Subsequently, the electric push rod 18 inside the placing rack 9 drives the support plate 6 to move, and the support plate 6 contacts the surface of the power circuit board in the groove 4, so as to facilitate the limiting treatment of the power circuit board placed in the placing rack 9 and prevent the power circuit board from shifting during testing;

[0029] When the power circuit board is fixed in the placing rack 9, the cylinder 1 inside the operation frame 3 drives the bracket 11 to move. Then, the motor A16 inside the bracket 11 drives the lead screw 13 to rotate. The transmission block 14 outside the lead screw 13 drives the electric telescopic rod 15 to move. The electric telescopic rod 15 drives the test probe 8 on the fixed block 17 to move, so that the test probe 8 contacts the power circuit board in the placing rack 9, thus facilitating the test treatment of different positions of the power circuit board and improving the test efficiency of the power circuit board;

[0030] When the power circuit board in the groove 4 of the placement rack 9 finishes the test, the test probe 8 separates from the power circuit board. Then, the motor B22 in the operation rack 3 converts the received electrical energy into mechanical energy.

[0036] During use, when the motor B22 drives the driving block 19 to rotate, the circular plate 20 outside the driving block 19 slides in the limiting groove 21 formed in the operation rack 3, improving the stability of the rotation of the driving block 19.

[0037] To enable the electrical equipment to work properly, by way of example, as Figure 1 、 Figure 2 and Figure 3 shown, the present utility model further includes that the input ends of the motor A16, the motor B22, the air cylinder 1, the electric telescopic rod 15, and the electric push rod 18 are all electrically connected to the power supply end of an external power supply.

[0038] During use, by connecting to an external power supply, the electrical equipment works properly.

[0039] When testing the power circuit board, first place the power circuit board in the groove 4 formed on the surface of the placement rack 9. Subsequently, the electric push rod 18 in the placement rack 9 drives the support plate 6 to move, and the support plate 6 contacts the surface of the power circuit board in the groove 4, thereby facilitating the limiting treatment of the power circuit board placed in the placement rack 9 and preventing the power circuit board from shifting during testing;

[0040] After the power circuit board is fixed in the placement rack 9, the air cylinder 1 in the operation rack 3 drives the support 11 to move. Then, the motor A16 in the support 11 drives the lead screw 13 to rotate. The transmission block 14 outside the lead screw 13 drives the electric telescopic rod 15 to move, and the electric telescopic rod 15 drives the test probe 8 on the fixed block 17 to move, so that the test probe 8 contacts the power circuit board in the placement rack 9, thereby facilitating the testing of different positions of the power circuit board and improving the testing efficiency of the power circuit board;

[0041] After the testing of the power circuit board in the groove 4 of the placement rack 9 is completed, the test probe 8 is separated from the power circuit board. Then, the motor B22 in the operation rack 3 converts the received electrical energy into mechanical energy. The motor B22 drives the driving block 19 to rotate, and the driving block 19 drives the placement rack 9 to rotate. The power circuit boards in other grooves 4 in the placement rack 9 move to below the test probe 8, thereby facilitating the testing of different power circuit boards;

[0042] When the air cylinder 1 drives the support 11 to move, the slider 12 outside the support 11 slides in the chute 10 formed in the operation rack 3, improving the stability of the support 11 moving in the operation rack 3;

[0043] When the power circuit board is fixed inside the groove 4, the support plate 6 and the rubber pad 2 in the groove 4 increase the friction force on the surface of the power circuit board, improving the stability of the power circuit board fixation;

[0044] When the motor B22 drives the driving block 19 to rotate, the circular plate 20 outside the driving block 19 slides in the limiting groove 21 formed in the operation rack 3, improving the stability of the driving block 19 rotating.
