Problems solved by technology

[0007] It can be seen that the traditional operation method is very cumbersome. During the power-on test process, a large number of power lines are required to be manually inserted at the entrance of the transmission line, then pulled out at the exit of the transmission line, and then sent back to the entrance. Repeated operations, work Heavy and highly confusing, and quite expensive to test

Embodiment 1

[0040] In this embodiment, a movable plug for electrical testing of household electrical appliances has a structure such as Figure 1~3 As shown, it is mainly composed of a base, a sliding seat, a plug, a screw, a wire, a roller, an axle and a conductive wheel.

[0041] The base is made of plastic insulating material, and its shape is a flat rectangular structure. In its length direction, dovetail chute is symmetrically processed to cooperate with the sliding seat (see image 3 ).

[0042] The sliding seat is also made of plastic insulating material and has an L-shaped structure (see figure 1 ), including the connected side and bottom plates. The lower part of the bottom plate is processed with symmetrical dovetail slide rails, which match with the base. Therefore, the sliding seat as a whole can slide left and right on the base. The upright part on the left side of the sliding seat is the side plate, which is processed with slots, which can be inserted into the special p...

Embodiment 2

[0047] This embodiment is a test device for conducting a power-on test on a household electrical appliance with the movable plug described in Embodiment 1, and the household electrical appliance tested is an electric rice cooker as an example.

[0048] Such as Figure 4 or Figure 5 As shown, the movable plugs are installed on the supporting plate of the conveying mechanism, and the installation distance between them is determined according to the external dimensions of the household appliances. The home appliance product in this embodiment takes an electric rice cooker as an example. On the supporting plate, a movable plug is installed on one side, and a positioning seat is installed on the corresponding other side. The positioning seat needs to be designed with reference to the foot of the home appliance, so that it can just clamp the home appliance. The positioning seats in this embodiment are 4 ring sleeves, which can just clamp the 4 feet of the rice cooker, and make t...

Abstract

The invention discloses a movable plug, a testing device and a testing method for power-on testing of a household electrical product. The movable plug comprises a base, a slide carriage, a plug member, a lead and conductive wheels. The base is provided with a chute. The bottom of the slide carriage is embedded into the chute. The plug member is arranged on the slide carriage. The bottom of the base is provided with the conductive wheels. The conductive wheels are connected with the plug member through the lead. The testing device comprises the movable plug, a positioning seat, a conveying mechanism, an electrode rail and a guide rail. The movable plug and the positioning seat are fixed on the conveying mechanism. The guide rail is arranged above the conveying mechanism, and the electrode rail is arranged below the conveying mechanism. In the guide rail, the distance between a power-on segment and the positioning seat is smaller than the distance between a power-off segment and the positioning seat, and is also smaller than a distance between a positioning segment and the positioning seat. The testing method comprises the steps of fixing the household electrical product on the positioning segment, inserting the movable plug into the household electrical product and performing power-on testing on the power-on segment, and separating the movable plug from the household electrical product at the power-off segment. The movable plug, the testing device and the testing method realize online power-on testing on the household electrical product.

Description

technical field [0001] The invention relates to the technical field of home appliance product testing, in particular to a movable plug, a test device and a test method for power-on testing of home appliance products. Background technique [0002] In the home appliance production line, after the home appliance product is assembled, various inspections are required, including power-on inspection. Only when each index is qualified can it be packaged as a finished product and leave the factory. [0003] Power-on inspection is a very important link, which can directly judge whether a home appliance product is qualified. Traditional home appliance testing is generally in the form of manual assistance. For example, in the power-on detection of the rice cooker, after the assembly is completed, the rice cooker needs to be powered on for a period of time to heat up to check whether the product is normal. The detection process is as follows: [0004] The conveyor line used for the ...
