Detailed Implementation

[0013] In the following description, embodiments of the PCB circuit board continuous loading electrical testing device of the present invention will be described with reference to the accompanying drawings.

[0014] Figure 1-4 This invention illustrates a continuous loading electrical testing device for PCB circuit boards according to an embodiment of the present invention. It includes an electrical testing device 1. It should be noted that the electrical testing device 1 is an automatic optical inspection device, a prior art product, such as the P4-18 manufactured by Suzhou Bosheng Precision Machinery and the M520 manufactured by Juzi Technology, etc., and therefore will not be elaborated upon further. Conveyors 2 are provided on both sides of the electrical testing device 1. A testing platform 3 is fixedly connected to the bottom of the inner cavity of the electrical testing device 1. Fixing frames 4 are fixedly connected to the front and rear sides of the inner cavity of the electrical testing device 1, and a space is provided between the two fixing frames 4. The device has a sliding frame 5, and the electrical testing equipment 1 has material feeding windows 8 on both sides. The sliding frame 5 reciprocates through the inner cavity of the material feeding windows 8. Suction components 6 are provided on both sides of the top of the sliding frame 5. The suction components 6 include cylinders 61 fixedly installed on both sides of the top of the sliding frame 5. Crosses 62 are provided on both sides of the bottom of the sliding frame 5. The output end of the cylinder 61 extends to the bottom of the sliding frame 5 and is fixedly connected to the crosses 62. The top end of the air pipe 63 extends to the top of the sliding frame 5 and is slidably connected to the sliding frame 5. The top of the crosses 62... Each of the four corners of the sliding frame 5 is provided with an air pipe 63 fixedly connected to it. A suction cup 64 connected to the bottom of each air pipe 63 is fixedly installed. A displacement assembly 7 is provided on the rear side of the top of the sliding frame 5. The displacement assembly 7 includes a servo motor 71 fixedly installed on the rear side of the inner cavity of the electrical measuring device 1. A drive gear 72 is fixedly connected to the output shaft of the servo motor 71. A rack 73 is fixedly connected to the rear side of the top of the sliding frame 5. The drive gear 72 and the rack 73 mesh. Four limiting pulleys 74 are rotatably connected to the front and rear sides of the sliding frame 5. Two fixed... Each of the fixed frames 4 has a limiting groove 75 on one side. The limiting pulley 74 is slidably connected to the inner cavity of the limiting groove 75. With the setting of the displacement component 7, the sliding frame 5 is driven and displaced by the servo motor 71 and the cooperation of the drive gear 72 and rack 73, so that the sliding frame 5 can slide left and right between the two fixed frames 4. At the same time, the limiting pulley 74 and the limiting groove 75 play a limiting and guiding role for the sliding frame 5, thereby improving the stability of the sliding frame 5 during the sliding process.

[0015] Working Principle: In use, the user transports the circuit board via the left-side conveyor 2. Once the circuit board reaches the designated position, the servo motor 71 starts and drives the drive gear 72 to rotate. During rotation, the drive gear 72, through its meshing rack 73, drives the sliding frame 5 to slide between the two fixed frames 4, causing the sliding frame 5 to reach the leftmost position. Subsequently, the cylinder 61 starts and pushes the cross 62 downward. As the cross 62 moves downward, it drives the air pipe 63 and suction cup 64 to slide downward, causing the suction cup 64 to contact the top of the circuit board. At this time, the external negative pressure air pump starts and applies pressure to the suction cup 64, causing the suction cup 64 to adhere to the top of the circuit board. Then, the cylinder 61 resets, and with the cooperation of the cross 62, the circuit board is driven towards... As the circuit board rises, the servo motor 71 starts and rotates in the opposite direction, causing the sliding frame 5 to slide to the right, so that the circuit board reaches the top of the testing platform 3. Then, the cylinder 61 starts again, and with the cooperation of the suction cup 64 and the cross 62, the circuit board is transported to the top of the testing platform 3. At this time, the external negative pressure air pump exhausts the air, causing the suction cup 64 to detach from the circuit board. Then, the electrical testing equipment 1 starts to test the circuit board. Since the suction assembly 6 is set in two groups, during use, the left suction assembly 6 can pick up the untested circuit board, and the right suction assembly 6 can pick up the tested circuit board. With the cooperation of the displacement assembly 7 and the sliding frame 5, the untested circuit board is automatically loaded, and the tested circuit board is automatically unloaded and transported by the two conveyors 2.

[0016] In summary, this PCB continuous board loading and electrical testing device, through the setting of displacement component 7, drives the sliding frame 5 to move horizontally. At the same time, with the cooperation of material suction component 6, it automatically picks up, loads and unloads the circuit board. With the cooperation of electrical testing equipment 1 and testing table 3, it tests the circuit board, thus achieving the purpose of uninterrupted material supply and continuous automatic testing.
