[0002] In the production process of electronic components, insulation and withstand voltage testing is a safety test requirement. Each product needs to be strictly tested before shipment, and 100% inspection is required. In the past two years, the PTC device new energy vehicle air heating core is a product with an aluminum shell. When testing, it must first be placed flat on the insulation and withstand voltage test board in an orderly manner (such as Figure 3 As shown), then press the red button on the handheld high-voltage gun with your finger to connect the positive and negative poles of each PTC device one by one. Existing PTC devices are high-end products, and the standard requirements are: each product is insulated and withstands voltage for 3-15s, so the output of operators in this process is very low, which seriously affects sales output. Moreover, when placed on the conductive plate, the number is about 25, and the straight-line distance from one end to the other is long, which often pulls and twists the power cord of the high-voltage gun, causing damage, affecting procurement costs and production progress. Then, when the operator holds the high-voltage gun for a long time, the probability of contact with the body will be greatly increased, and employees sometimes touch it, causing safety hazards.
