[0025] Specifically, the receiving assembly 7 includes a receiving plate 71, a first spring 72, a movable groove 73, a receiving box 74, a movable plate 75 and a pulling member 76. The receiving box 74 is inserted into the interior of the good and bad tray 5 and the workbench 6. A pulling member 76 is provided between the good and bad tray 5 and the receiving box 74. The receiving plate 71 is provided inside the receiving box 74. Both ends of the receiving plate 71 are connected to the movable plate 75. A movable groove 73 is provided on the side wall of the receiving box 74 at a position corresponding to the movable plate 75. A first spring 72 is connected between the movable plate 75 and the movable groove 73.

[0026] By adopting the above technical solution, after the circuit board is inspected, the rotating movement mechanism 1 is used to drive the moving mechanism 2 to rotate and move. The rotating movement of the moving mechanism 2 drives the circuit board to move and place it on one of the receiving plates 71. The receiving plate 71 moves due to the squeezing effect of the circuit board. The movement of the receiving plate 71 drives the moving plate 75 to move inside the moving groove 73. The moving plate 75 moves to squeeze the first spring 72, so that the circuit board moves and is stored in the receiving box 74. After the receiving box 74 receives multiple circuit boards, the lifting member 76 is used to drive the receiving box 74 to move away from the good and bad tray 5 and the workbench 6, and then the circuit board is taken out from the receiving box 74.

[0027] Specifically, the interior of the movable groove 73 is connected to a guide post, and a guide hole is provided on the movable plate 75 at a position corresponding to the guide post.

[0031] When this embodiment is used, multiple circuit boards to be inspected are placed on the storage tray 3, and the operator uses the controller 4 to control the rotating and moving mechanism 1 to drive the moving mechanism 2 to move down and close to clamp one of the circuit boards, and then uses the detection mechanism 8 to replace manual operation to perform hole position visual inspection on the circuit board. After the inspection is completed, the operator operates the controller 4 again to drive the rotating and moving mechanism 1 to drive the moving mechanism 2 to rotate and move, and the moving mechanism 2 rotates and moves to drive the circuit board to rotate and move onto one of the receiving plates 71. The receiving plate 71 is squeezed by the circuit board and moves. The movement of the receiving plate 71 drives the moving plate 75 to move inside the moving groove 73. The moving plate 75 moves to squeeze the first spring 72, so that the circuit board is moved and stored in the receiving box 74, and then it is used again. The controller 4 controls the rotating movement mechanism 1 to drive the moving mechanism 2 to rotate and move to the top of the storage tray 3, and then uses the same method to inspect the remaining circuit boards on the storage tray 3, and moves the qualified circuit boards and unqualified circuit boards that have completed the inspection to the inside of the receiving box 74, which is convenient for storing and placing multiple circuit boards and can ensure the stability of the stored and placed circuit boards. After the receiving box 74 receives multiple circuit boards, the lifting rod 762 is moved upward, and the lifting rod 762 moves upward to drive the positioning rod 761 and the receiving box 74 to move away from the positioning groove 763 and the good and bad tray 5 and the workbench 6, and then the receiving plate 71 is lifted by the bottom end of the receiving box 74. The movement of the receiving plate 71 drives the circuit boards to move out of the receiving box 74, making it convenient for the operator to take the circuit boards.

Then the plug-in rods 94 are released, and the second spring 93 loses the external force and returns to its original state, driving the plug-in rods 94 to move and be plugged into the plug-in slots 95. The plug-in rods 94 can be used to plug and fix the installation frame 97, which facilitates the disassembly and assembly of the transparent plate 96.

[0036] When this embodiment is in use, the two plug-in rods 94 are moved in opposite directions so that they are moved and retracted into the plug-in cavity 92. The plug-in rods 94 move to squeeze the second spring 93, and then the installation frame 97 is moved and placed into the external frame 91. The plug-in rods 94 are then released, and the second spring 93 loses the external force and returns to its original state, driving the plug-in rods 94 to move and be plugged into the plug-in slots 95. The plug-in rods 94 can be used to plug and fix the installation frame 97, which facilitates the disassembly and assembly of the transparent plate 96. The transparent plate 96 can ensure the normal operation of the detection mechanism 8 while providing protection for the detection mechanism 8.

A plurality of pressure sensors are installed on the surface of the baffle. The controller 4 is electrically connected to the second motor and the pressure sensor. When in use, after adjusting the various parameters of the controller 4, the controller 4 controls the second motor to rotate, drives the saw gear to rotate, causes the sawtooth rod to retract inward, and shortens the distance between the baffles until the pressure data returned by the pressure sensor on the baffle reaches the pressure value set in advance by the staff. At this time, the two baffles have clamped the first circuit board to be inspected.

[0039] The structure and principle of the detection mechanism 8 composed of an infrared rangefinder and a camera in the present utility model have been disclosed in a circuit board intelligent visual detection device disclosed in Chinese patent application No. 202222481145.0.
