Detailed Implementation

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] Example 1

[0022] A semi-automatic flying probe testing machine and robotic arm, such as Figures 1-4 As shown, the device includes a testing machine 1, a placement platform 2 connected to the middle of the testing machine 1, a worktable 3 connected to the right side of the testing machine 1, an electric guide rail 4 connected between the left and right sides of the upper part of the worktable 3, two electric suction cups 5 slidably connected to the electric guide rail 4, calibration mechanisms 6 are provided on both the left and right sides of the worktable 3, each calibration mechanism 6 includes a mounting base 61, symmetrically mounted bases 61 are connected to the upper sides of both the left and right sides of the worktable 3, guide members 62 are connected to both the left and right sides of the mounting base 61, and adjacent guide members 62 are slidably connected to each other. The clamping plates 63 are made of rubber on their inner sides and are slidably connected to the adjacent mounting bases 61. The lower outer side of each clamping plate 63 is connected to a first guide rod 66, and each first guide rod 66 is provided with a limit block. The first guide rod 66 is slidably connected to the adjacent mounting bases 61. The middle outer side of each clamping plate 63 is slidably connected to a latch 64, and each latch 64 is provided with a circular assisting component. Each latch 64 is slidably connected to the adjacent mounting bases 61, and a spring 65 is connected between each latch 64 and the adjacent clamping plate 63.

[0023] It should be noted that the PCB is an important component for connecting and supporting electronic components in electronic equipment, and the PCB forms a circuit network by laying a conductive path on an insulating substrate to realize electrical connection between electronic components. In the production process of the PCB, the electrical connection and defects on the PCB are usually detected by a semi-automatic flying probe test. When the semi-automatic flying probe tester 1 is running, the placement of the PCB before testing and the taking out of the PCB after testing are usually completed in combination with a mechanical arm. First, the untested PCB is placed on the left part of the workbench 3 by manual operation, and then the left electric suction cup 5 adsorbs the PCB. Then, the electric guide rail 4 drives the electric suction cup 5 and the PCB to move to the left, until the left PCB moves to the upper side of the placement table 2. Then, the PCB is separated from the adsorption of the electric suction cup 5, so that the PCB falls onto the placement table 2. The electric suction cup 5 is reset to the right, so as to perform the flying probe test. After the test is completed, the left electric suction cup 5 adsorbs the untested PCB again, and the electric guide rail 4 drives the electric suction cup 5 to move again. When the right electric suction cup 5 moves to the placement table 2, the right electric suction cup 5 adsorbs the tested PCB. Then, the electric suction cup 5 moves to the right. When the left electric suction cup 5 moves to the placement table 2, the untested PCB is placed again. The right electric suction cup 5 drives the tested PCB to move, until the tested PCB is placed on the right side of the workbench 3. In this way, the test operation is repeated. However, when the PCB is stacked by manual operation, there may be errors, which may cause the position of the PCB on the placement table 2 to deviate, affecting the accuracy and reliability of the test result of the tester 1. The PCB needs to be centered and calibrated when it is stacked. First, the untested PCB is placed on the upper side of the left part of the workbench 3, so that the untested PCB corresponds to the initial position of the left electric suction cup 5. Then, the clamping bolt 64 is pushed upward, so that the spring 65 is compressed, and the clamping plate 63 is separated from the locking state of the clamping bolt 64. Then, the clamping plate 63 is slid, and the position of the clamping plate 63 is adjusted according to the specification of the PCB, so that the clamping plates 63 on the front and rear sides clamp the PCB, thereby centering and calibrating the PCB. Then, the clamping bolt 64 is reset downward, so that the clamping bolt 64 locks the clamping plate 63 and the adjacent mounting seat 61 again. The rubber material on the inner side of the clamping plate 63 protects the PCB. Centering and calibrating the PCB can reduce the error when the PCB is placed, thereby improving the accuracy of the PCB test.

[0024] Embodiment 2

[0025] On the basis of embodiment 1, as Figure 1 , Figure 2 and Figure 5As shown, further comprising a lifting mechanism 7, the lifting mechanism 7 comprises a mounting frame 71, the workbench 3 left and right two parts are connected with the mounting frame 71, the mounting frame 71 is connected with the reinforcing triangular rib plate, the mounting frame 71 is installed with the electric push rod 72, the electric push rod 72 telescopic end is connected with the top plate 74, the top plate 74 is located in the lower part of adjacent electric suction cup 5, the mounting frame 71 is also connected with the second guide rod 73, the second guide rod 73 upper part is connected with the adjacent top plate 74.

[0026] It should be noted that, since the adsorption capacity of the electric suction cup 5 is affected by the adsorption distance, when the remaining amount of the untested PCB board is insufficient, the distance between the electric suction cup 5 and the PCB board is enlarged, which is not conducive to adsorbing the PCB board, the utility model sets up the lifting mechanism 7, when the distance between the PCB board and the electric suction cup 5 is larger, the electric push rod 72 can be started, the telescopic end of the electric push rod 72 drives the top plate 74 to move upward, thereby ejecting the PCB board, and further shortening the distance between the PCB board and the electric suction cup 5, so that the electric suction cup 5 is more convenient to adsorb.
