Description

Technical Field

[0001] The present application relates to the technical field of circuit board testing tooling, and in particular to a double-board hot air barrel automatic testing tooling. Background Art

[0002] The hot air blower usually includes a heating wire and a motor. The electric heating wire can heat the air when it is powered on. The motor drives the fan blades to rotate so that hot air can be blown out of the hot air blower for people to use. The hot air blower is usually equipped with two circuit boards for controlling the motor and the electric heating wire respectively. Before assembling the hot air blower, the parameters or functions of the circuit board need to be tested.

[0003] Usually, the staff makes the probe of the multimeter abut the measuring point position on the circuit board, and then judges whether the circuit board function is normal through the data on the multimeter display screen. However, this method is relatively cumbersome, and it is not easy for the staff to abut the probe at the measuring point of the circuit board. With the improvement of the staff's requirements for test efficiency, a tool for testing the function of the circuit board has also appeared. For example, a circuit board test tool is disclosed in the patent with publication number CN104535916A, which includes a frame and a lower template, the lower template is used to place the circuit board, and the upper template is slidably connected to the frame. A probe group is provided on the upper template, and the probe group is connected to the circuit board tester. By moving the upper template, the probe group can be driven to contact the circuit board to achieve the test of the circuit board. A handle is set on the upper template board to facilitate the staff to move the upper template.

[0004] However, the above-mentioned circuit board testing tooling still has some drawbacks. For example, workers are required to manually move the upper template and the lower template, which results in a heavy workload for the workers. In addition, the circuit boards of the hot air cylinder are tested separately, resulting in a slow test efficiency. Furthermore, the actual state of the two circuit boards when working in linkage cannot be tested, and the test accuracy needs to be improved. Utility Model Content
