[0047] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0048] The following description refers to the accompanying drawings. Figures 1-2 The test device provided by the embodiments of the present application is described below, which includes a base 100, a mounting member 200, a plurality of flexible members 300 and a docking member 400.

[0049] The mounting member 200 is movably arranged on the base 100 and forms a through slot 210; the plurality of flexible members 300 are distributed in a circumferential direction at intervals, and the flexible members 300 are arranged on the mounting member 200 and close to the through slot 210; the docking member 400 is arranged on a side of the flexible member 300 away from the mounting member 200, and the docking member 400 is used for plugging with a to-be-tested member. The material of the flexible member 300 includes but is not limited to rubber, so as to realize that the docking member 400 has an elastic floating amount relative to the mounting member 200. It should be noted that the shape and size of the through slot 210 and the flexible member 300 can be designed according to actual needs, and the embodiments do not make specific limitations on this.

[0050] It can be understood that the mounting member 200 is movably arranged on the base 100 so as to align the to-be-tested member, and the elastic floating amount provided by the flexible member 300 is used to compensate for the position offset amount when the docking member 400 is plugged with the to-be-tested member, which helps to improve the plugging efficiency, reduce the wear of plugging, and prolong the service life of the docking member 400 and the to-be-tested member. At the same time, the mounting member 200 forms the through slot 210, and the flexible member 300 is close to the through slot 210 and connected with the mounting member 200 and the docking member 400 respectively, so that the through slot 210 and the docking member 400 are arranged at intervals along the penetrating direction of the through slot 210, which facilitates the wires required for power-on test to pass through the through slot 210 and the docking member 400 for connection, reduces the possibility of wire and air pipe bending or interfering with each other, and makes the structure of the whole test device more compact, improves the accuracy and reliability of the test.

[0051] According to the test device provided by the embodiments of the present application, the plugging efficiency and accuracy in the automatic test process are improved, the wear is reduced, and the test qualification rate and accuracy are improved.

[0052] In some embodiments, as shown in Figure 1 and Figure 2 shown, the to-be-tested piece forms a positioning hole, the docking piece 400 includes a body 410 and a positioning piece 420, the body 410 is connected with the flexible piece 300; the positioning piece 420 is protruded on the side of the body 410 away from the flexible piece 300, and is used for plug-in cooperation with the positioning hole. It should be noted that the shape and size of the positioning hole and the positioning piece 420 can be designed according to actual needs, and the embodiment does not make specific limitation on this.

[0053] It can be understood that through the matched positioning hole and the positioning piece 420, the plug-in efficiency is improved, not only the to-be-tested piece can be quickly and easily aligned with the docking piece 400, but also the elastic floating of the flexible piece 300 is guided. At the same time, the protrusion of the positioning piece 420 on the body 410 can also enhance the mechanical stability of the connection between the docking piece 400 and the to-be-tested piece.

[0054] In some embodiments, as shown in Figure 1 , the positioning piece 420 is provided with two, and the two positioning pieces 420 are diagonally distributed.

[0055] It can be understood that by providing two positioning pieces 420, the contact area with the to-be-tested piece is increased, the alignment error caused by single-point positioning is reduced, the accuracy of docking is improved, and the positioning accuracy is improved. At the same time, the two positioning pieces 420 are diagonally arranged, which helps to reduce the inclination or rotation of the to-be-tested piece during docking, ensures the straightness and consistency of docking, and adapts to to-be-tested pieces of different shapes and sizes. It can also better guide the elastic floating of the flexible piece 300, ensure that the flexible piece 300 can be uniformly deformed in flexibility during docking, and reduce local stress concentration.

[0056] In some embodiments, as shown in Figure 1 , the docking piece 400 further includes a plurality of test probes 430 and a plurality of air pipe plugs 440, the test probes 430 are provided in the body 410 and protrude from the side of the body 410 away from the flexible piece 300, and are used for circuit connection with the to-be-tested piece; the air pipe plug 440 is provided in the body 410 and protrudes from the side of the body 410 away from the flexible piece 300, and is used for gas path connection with the to-be-tested piece. The test probe 430 includes but is not limited to a pogo pin. It should be noted that the shape, number and specific distribution of each of the test probe 430 and the air pipe plug 440 can be designed according to actual needs, and the embodiment does not make specific limitation on this.

[0057] It can be understood that by arranging the test probes 430 and the tracheal plugs 440 on the body 410, the electrical and air path connections are integrated on the same docking piece 400, which reduces the steps that need to be operated separately, thereby shortening the test period and improving the overall test efficiency.

At the same time, the projection of the flexible member 300 is located in the projection of the docking member 400, that is, the bottom area of the groove 411 is greater than the area of the through groove 210, which can also facilitate to increase the accommodation space of the wires and the air pipe and improve the heat dissipation efficiency.

[0065] It can be understood that by adjustably arranging the mounting member 200 in the first connecting seat 500 along the second direction, and adjustably arranging the first connecting seat 500 in the second connecting seat 600 along the first direction, the alignment of the positioning hole and the positioning member 420 is realized, so as to accurately plug the docking member 400 and the to-be-tested member subsequently. At the same time, after the docking member 400 and the to-be-tested member are aligned, the driving member 700 drives the second connecting seat 600 to move along the third direction, so as to make the docking member 400 and the to-be-tested member close to each other until the positioning hole and the positioning column are plugged and matched, and the test probe 430 and the air pipe plug 440 are respectively connected with the circuit and the air circuit of the to-be-tested member.
