- the clamping claw 4 clamps and fixes the setting direction of the circuit board
- the clamping claw 4 is directly fixed on the transmission belt body of the transmission belt assembly 323 in the clamp guide device, and is carried by the transmission belt between the loading and unloading area 2 and the work area 1.
- the loading and unloading mechanism can also be a loading and unloading mechanism with an upper side feeding structure as shown in Figures 9 and 10, and the loading and unloading area is located on the upper side of the working area, and The two are located in the same vertical plane, conveying materials from top to bottom. With this layout, the upper space can be used more reasonably. In specific application scenarios, this mechanism is optional.
- the circuit board that needs to be tested is taken out of the reclaiming box by the material transfer equipment, and placed in the loading and unloading area of the loading and unloading mechanism in the test equipment, and the material is loaded from the side of the docking end of the test equipment corresponding to the carrying mechanism and aligned by the fixture.
- the fixture guide device is activated and driven by the fixture guide device, the circuit board is transported to the work area through the docking end, and then the circuit board is tested by the test device.
- the control The fixture guide device is reversed so that the fixture guide device outputs the fixture from the working area to the loading and unloading area through the docking end.
- the material transfer equipment then removes the tested circuit board from the loading and unloading mechanism and transports it to the next station or storage. In the material box, the process of loading and unloading and testing the circuit board is completed.
