Technical Field
[0001] This utility model relates to the field of chip resistor technology, and in particular to a chip resistor testing device. Background Technology
[0002] Surface mount resistors, also known as chip resistors, are a type of metal-glass enamel resistor. They are made by mixing metal powder and glass enamel powder and printing the mixture onto a substrate using screen printing. They are resistant to moisture and high temperatures and have a small temperature coefficient. After manufacturing surface mount resistors, it is necessary to test their resistance to ensure the quality of the product.
[0003] The applicant discovered through a search that a Chinese patent discloses "A chip resistor testing device" with publication (announcement) number "CN220040601U".

The number of placement slots can help to test multiple chip resistors simultaneously, improving testing efficiency. However, after the device finishes testing, manual collection is required, which is slow and can easily become a bottleneck in the production line, affecting overall efficiency. Long-term repetitive manual collection work can easily lead to fatigue and increase labor intensity. Therefore, we propose a chip resistor testing device. Utility Model Content

[0027] Example 2:
[0028] Please see the appendix Figure 5 and attached Figure 6The receiving structure 4 includes a detection table 41, a connecting shaft 42, and a storage box 48. The detection table 41 is rotatably installed in the circular through groove of the operating table 11 via the connecting shaft 42, and one end of the connecting shaft 42 extends through the operating table 11 to the outside of the operating table 11.
