Alternatively, the positioning mechanism 40 is coupled to the in-place sensing unit, which may be a communication connection formed directly between the two or a coupling connection formed by an industrial personal computer, and when the in-place sensing unit senses that the product 200 is in place, the positioning mechanism 40 learns that the product 200 is in place, so as to start operation. In addition, the positioning mechanism 40 is coupled with the energizing mechanism 20, so that communication connection can be directly formed between the positioning mechanism 40 and the energizing mechanism 20, or coupling connection can be formed between the positioning mechanism and the energizing mechanism through an industrial personal computer, and after the product 200 to be measured is positioned through the positioning mechanism 40, the energizing mechanism 20 learns that the product 200 to be measured has been positioned, so that the positioning mechanism is electrically connected with the product 200 to be measured, and the energizing mechanism 20 and the energizing interface 201 of the product 200 to be measured can be connected efficiently, low-resistance and safely.

Further, in some embodiments, the positioning mechanism 40 includes a pose defining portion movably connected to the test bench 10, where the pose defining portion includes at least a first limiting surface and a second limiting surface that are not coplanar, when the tested product 200 is located at a location designated by the test bench 10 and is to be tested, the pose defining portion can relatively move close to the carrier 11 and drive the first limiting surface and the second limiting surface to respectively abut against at least part of the outer side of the adapting carrier 11, and after the test is finished, the pose defining portion relatively moves away from the carrier 11, so as to drive the first limiting surface and the second limiting surface to separate from the surface of the carrier 11 to release the locking of the carrier 11.
Specifically, in the embodiment shown in fig. 4 to 6, the holding assembly 42 includes two holding units, and fig. 4 shows one of the holding units, where the holding unit includes a holding driver 421 mounted on the test chamber 12, and a holding element 422 connected to an output end of the holding driver 421.

In the embodiment shown in fig. 1 to 7, the tested product 200 is already installed in the adapting portion 112 before being located on the test bench 10, and is adapted to be connected with the adapting portion 112 into a whole, so that the clamping element 422 can clamp the carrier 11 to fix the tested product 200, and the failure of the tested product 200 caused by directly applying clamping pressure to the tested product 200 can be avoided.
As shown in fig. 7, the base portion 111 and the adapting portion 112 are both substantially rectangular structures, and the clamping elements 422 form a pose limiting portion, each clamping element 422 includes two first limiting surfaces and two second limiting surfaces perpendicular to each other, the two clamping elements 422 respectively clamp two diagonal edges of the base portion 111 or the adapting portion 112, and the first limiting surfaces and the second limiting surfaces of each clamping element 422 respectively abut against two adjacent sides of the base portion 111 or the adapting portion 112. The arrangement can overcome the defect that the clamping element 422 clamps the carrying platform 11 and slides relative to the carrying platform 11, improves the stability of the clamping assembly 42 for clamping the carrying platform 11, and the clamping assembly 42 is matched with the pressing assembly 41, so that six spatial degrees of freedom of the carrying platform 11 and the tested product 200 can be comprehensively limited, and the tested product 200 is prevented from shaking due to the testing force of the executing mechanism 30.

When the tested product 200 arrives at the place to be tested specified in the test bench 10, the pull-out driving member 22 drives the third interface 21 to move close to the tested product 200 until the third interface 21 and the power-on interface 201 connected to the tested product 200 are moved, and after the test is finished, the pull-out driving member 22 drives the third interface 21 to move away from the tested product 200 so as to separate the third interface 21 from the tested product 200. Optionally, the pull-out actuator 22 is coupled to the positioning mechanism 40, the actuator 30, and the in-place induction unit.

After the tested product 200 is loaded into the adapting portion 112, the direction of the power-on interface 201 of the tested product 200 is in the horizontal direction, one side of the tested product 200, on which the power-on interface 201 is arranged, is opposite to one side of the abutting surface 1122 of the abutting plate, where the tested product 200 contacts the abutting plate, while the third interface 21 is just opposite to the abutting surface 1122 of the abutting plate, the contact-pull driving piece 22 drives the third interface 21 to move close to the abutting surface 1122 so as to realize power-on to the tested product 200, and drives the third interface 21 to move away from the abutting surface 1122 so as to disconnect the third interface 21 from the tested product 200 and then power-off. The process of electrically connecting the third interface 21 to the tested product 200 is accompanied by that the third interface 21 applies a side pushing force to one side of the tested product 200, and the abutting plate abuts against the other side of the tested product 200 through the abutting surface 1122 so as to consolidate the pose of the tested product 200, so that the tested product 200 maintains a force balance under the action of the third interface 21 and the abutting plate, and no overturning occurs during power connection.
