A cylinder 1 72 is fixedly arranged on the left side of the top of the connecting plate 70, and a movable rod of the cylinder 1 72 is fixedly connected to a detection pressure plate 73. The detection pressure plate 73 is located in the center directly above the detection table 74.

The transmission group 8 consists of a motor, two mutually meshing gears of the same size, a screw and a slider. The two gears of the transmission group 8 are respectively connected to the motor output shaft and the left part of the screw. A connecting frame 9 is fixedly arranged at the lower part of the slider of the transmission group 8. Cylinders 2 10 are installed on the left and right sides of the lower part of the connecting frame 9. Suction cup frames 11 are connected to the movable rods of cylinders 2 10. When the suction cup frame 11 moves, the connecting plate 70 of 7 on the electric slide rail 2 will move backward and be misaligned with the suction cup frame 11 on the connecting frame 9.

[0022] Initially, the loading platform 6 is located at the front position on the electric slide rail 5, the loading plate on the loading platform 6 is located outside the equipment, the connecting plate 70 is located at the rear position of the electric slide rail, the slider on the transmission group 8 is located at the right position of the screw rod, the suction cup frame 11 on the right side of the connecting frame 9 is located directly above the electric slide rail 5, and the movable rods of the cylinder 2 10 are all in a retracted state, and the suction cup on the left is located directly above the detection table 74. When the circuit board needs to be inspected, the finished circuit boards to be inspected are stacked and placed in the center position on the loading plate, and then the electric slide rail 5 is controlled to move the loading platform 6 to the rear position of the electric slide rail 5. When the loading plate of the loading platform 6 and the detection table 74 are aligned on the same line, the electric slide rail 5 is controlled to stop. At this time, the loading The feeding plate of table 6 will move to the position just below the right suction cup frame 11, and then the right suction cup frame 11 will be controlled to move downward by the right cylinder 10. When the suction cup on the suction cup frame 11 contacts the top of the topmost layer of circuit boards on the feeding table 6, the circuit board will be sucked, and the right suction cup frame 11 will be driven by the right cylinder 10 to lift the circuit board, and then the connecting frame 9 will be driven to move to the left by the transmission group 8. When the circuit board on the right suction cup frame 11 moves to the position just above the testing table 74, the right suction cup frame 11 is controlled to move downward to place the circuit board on the testing table 74. Then, the right cylinder 10 is controlled to drive the suction cup frame 11 to move upward and reset. At the same time, the transmission group 8 drives the connecting frame 9 to move to the right and reset. At this time, the suction cup frame 11 on the left is in the Above the inspection table 74, the suction cup frame 11 on the right is located above the loading table 6, and then the electric slide rail 2 7 is controlled to drive the connecting plate 70 to move forward, and the cylinder 1 72 and the inspection pressure plate 73 on the connecting plate 70 move forward with the connecting plate 70. When the inspection pressure plate 73 is located directly above the circuit board on the inspection table 74, the electric slide rail 2 7 is controlled to stop working, and then the cylinder 1 72 is controlled to extend the movable rod to drive the inspection pressure plate 73 to move downward. The inspection pressure plate 73 will contact the circuit board on the inspection table 74, and the connectivity of each component and circuit on the circuit board will be tested by presetting multiple detection probes. The results of the test will be displayed on the control screen 3. After the test is completed, the cylinder 1 72 will drive the inspection pressure plate 73 to move upward, and at the same time The electric slide rail 2 7 drives the connecting plate 70 to move backward and reset, and the connecting plate 70 moves backward to be misaligned with the connecting frame 9 and the suction cup frame 11 for taking materials, so as to avoid the collision between the cylinder 1 72 and the detection pressure plate 73 and the suction cup frame 11 on the connecting frame 9. At this time, the two cylinders 2 10 are controlled to drive the suction cup frame 11 to move downward to take materials. The suction cup frame 11 on the left side will suck the circuit board after inspection on the detection table 74, and the suction cup frame 11 on the right side will suck the top layer of circuit boards on the loading table 6.

The airflow direction blown by the ion fan 15 is the vacant position between the unloading plate and the loading plate. The ion fan 15 can generate a large amount of airflow with positive and negative charges. These airflows can neutralize the static electricity on the surface of the object. The ion fan 15 has a good anti-static performance, which can effectively prevent static electricity pollution and damage during circuit board detection.

[0026] When the circuit boards are stacked on the loading plate, the positioning grooves on the loading plate can guide the circuit boards when placing them, and cooperate with the four positioning rods 14 to clamp the edges of the circuit boards to achieve the positioning and placement of the circuit boards, so as to avoid the circuit boards from being skewed when the suction cup frame 11 takes the materials, thereby affecting the detection effect. When the cylinder 1 72 on the connecting plate 70 extends the movable rod to press the detection pressure plate 73 to perform the connectivity detection, the visual inspection instrument 71 on the right side of the connecting plate 70 will perform the appearance inspection on the circuit boards stacked on the top layer of the loading platform 6. When the appearance inspection of the circuit boards finds problems, the problem will be detected directly through the two consecutive material taking and discharging operations of the connecting frame 9. The circuit board in question is placed on the unloading table 61, and people take the circuit board away directly. Before the connectivity test, the circuit board is preliminarily tested. The welding effect of the circuit board components, whether the circuit is wrong, and the surface cleanliness of the circuit board are pre-checked by the visual inspection instrument 71. The defective circuit board is directly unloaded without connectivity test, so as to avoid invalid test, shorten the test time, and improve the test efficiency. At the same time, in the process of moving the circuit board on the loading table 6 to the testing table 74, the ion fan 15 is started, and the airflow blown by the ion fan 15 is used to remove static electricity from the circuit board to prevent static electricity pollution and damage during detection.

[0027] In a preferred embodiment: the detection pressure plate 73 on the cylinder 72 is a quick-install and quick-disassemble device. When testing circuit boards of different models, the detection pressure plate 73 can be quickly replaced and installed accordingly, reducing the time waste of component replacement.
