The test device for the power supply automatic assembly jig according to claim 9, wherein: the lifting assembly comprises guide rods (143) and lifting cylinders (144), wherein the guide rods (143) comprise at least two guide rods, the guide rods (143) are slidably inserted into the test support (141) along the vertical direction, the upper ends of the guide rods (143) are connected to the bottom of the sliding plate (142), and the lower ends of the guide rods (143) are connected to the upper part of the test support (145); the lifting cylinder (144) is vertically arranged on the sliding plate (142), and an output shaft of the lifting cylinder (144) penetrates through the sliding plate (142) to be connected to the test bracket (141); when the lifting cylinder (144) drives the output shaft to extend downwards, the reaction force of the test support (141) to the output shaft of the lifting cylinder (144) pushes the sliding plate (142) and the test support (145) to move upwards, and the sliding plate and the test support are guided and limited through the guide rod (143); when the output end of the lifting cylinder (144) is retracted upwards, the sliding plate (142) and the test support (145) move downwards;

The test support (145) is of a rectangular frame structure, and a rectangular through hole is formed in the middle of the test support, so that a power supply on the jig passes through the rectangular through hole and is electrically connected with the test assembly; strip-shaped groove bodies are respectively arranged on two side edges of the test support (145); the clamping jig assembly is arranged in the strip-shaped groove body;

a through groove (1410) which extends obliquely to the inner side of the test support (145) is formed in the linear slide seat (148); the connecting shaft (1411) is vertically inserted into the through groove (1410), and the connecting shaft (1411) freely slides along the through groove (1410); the inserting rods (1412) comprise at least two inserting rods (1412) which are arranged below the test support (145), and the inserting rods (1412) are fixedly connected with the lower ends of the connecting shafts (1411); when the clamp jig cylinder (147) drives the linear sliding seat (148) to slide along the linear sliding rail (149), the through groove (1410) drives the inserting rod (1412) to move towards the inner side of the test support (145) through the connecting shaft (1411) so as to be inserted into the test jacks (12) at the front side and the rear side of the jig base (1), so that the jig base (1) is clamped and fixed;

the test assembly comprises at least two power supply components which are arranged corresponding to the jig seat (1) in the vertical direction, so that the at least two power supply components on the jig seat can be tested at one time; the test assembly comprises a first test seat (1413) and a second test seat (1414), wherein the first test seat (1413) is arranged at the bottom of the test bracket (141) and is close to the front side part of the test bracket (141); a first conducting rod (1415) is arranged on the first test seat (1413), and the first conducting rod (1415) is arranged corresponding to the electric connecting sheet on the upper cover (01) in the vertical direction;

The second test seat (1414) is arranged on the rear side of the first test seat (1413); the second test seat (1414) is provided with a second conducting rod (1416), and the second conducting rod (1416) is arranged corresponding to the test hole (08) on the test seat (02) in the vertical direction; the first conductive rod (1415) and the second conductive rod (1416) are electrically connected with an external testing device; during testing, the clamp jig assembly clamps and drives the jig base (1) to ascend until the first conductive rod (1415) and the second conductive rod (1416) are respectively connected with the electric connection piece and the test hole (08), so that a complete circuit is formed among the PCB (04), the DC line (05), the conductive jack, the test hole (08), the first conductive rod (1415), the second conductive rod (1416) and the test device, and the power supply parameter is tested.
