[0044] Furthermore, the push plate 8 can push qualified sliding gate electrodes onto the first conveyor belt 7, and push unqualified sliding gate electrodes onto the second conveyor belt 18, thereby completing the quality sorting of the sliding gate electrodes.

[0045] The working principle of the present invention is as follows: firstly, the sliding door electrode is placed on the corresponding detection plate 25 and located inside the groove 5, and the rotating disk 2 is driven to rotate by the rotating motor (rotating 90 degrees each time);

[0046] In the first step, the turntable 2 rotates to drive the detection seat 4 and the L-shaped plate 6 and the components thereon to rotate together, and the first connecting plate 15 rotates to drive the first slide post 16 to rotate. Due to the setting of the first folding groove, the first slide post 16 will also move along the first folding groove as a path during revolution. The first slide post 16 will move to the first lower holding section 10 through the corresponding first moving section 11, and the first slide post 16 will drive the first connecting plate 15, the connecting plate 9 and the detection needle 17 to move downward, so that the detection needle 17 can detect the sliding door electrode. If the sliding door electrode is accessible, the drive motor 40 will work and drive the cam 3 9 rotates, the cam 39 rotates to drive the U-shaped plate 28 to move and make the first spring rod 38 generate elastic force, the U-shaped plate 28 moves to drive the second slide post 29 to move, the second slide post 29 moves to drive the limit plate 30 to insert into the vertical slot 34, and the baffle 35 connected by the one-way hinge will limit the limit plate 30. At this time, the second slide post 29 is located inside the second lower holding section 31. If the sliding door electrode is short-circuited or open-circuited, the drive motor 40 will not work, and further the second slide post 29 will not enter the second lower holding section 31 (the third slide post 20 has been sliding in the third lower holding section 24);

[0047] In the second step, the turntable 2 continues to drive the components thereon to rotate. At this time, the first slide post 16 will pass through another first moving section 11 and enter the first upper holding section 12, so that the connecting plate 9 can drive the detection needle 17 to move upward. In the second half of the movement, the third slide post 20 will pass through the corresponding third moving section 23 and enter the third upper holding section 22. In this process, the third slide post 20 will drive the third connecting plate 19, the slide plate 36, the second spring rod and the detection plate 25 to move upward (the slide plate 36 is flush with the groove 5 at this time), and the second slide post 29 will move upward inside the second lower holding section 31 (the second lower holding section 31 has a certain width);

[0048] In the third step, the turntable 2 continues to drive the components thereon to rotate. At this time, the first slide post 16 will move inside the first upper holding section 12, and the third slide post 20 will move inside the third upper holding section 22. If the sliding door electrode is qualified for the passage, the second slide post 29 will pass through the second moving section 32 and enter the second upper holding section 33, so that the second slide post 29 can drive the U-shaped plate 28 to move upward, and the U-shaped plate 28 moves upward to drive the detection plate 25 to move upward, so that the detection plate 25 can be raised by a certain distance (the second spring rod generates tension). If the sliding door electrode is unqualified for open circuit or short circuit, the second slide post 29 is not affected by the second limit ring 14, and then the push plate 8 can be pushed to move by the electric telescopic rod 26. The push plate 8 can push the qualified sliding door electrode to the first conveyor belt 7, and push the unqualified sliding door electrode to the second conveyor belt 18, thereby completing the quality sorting of the sliding door electrode;

[0049] Step 4: The turntable 2 continues to drive the components thereon to rotate, the first slide post 16 moves inside the first upper holding section 12, the third slide post 20 passes through the corresponding third moving section 23 and enters the third lower holding section 24, the second slide post 29 slides off the second upper holding section 33 and separates from the notch and the second limiting ring 14, then the elastic force generated by the first spring rod 38 and the tension generated by the second spring rod will reset the detection plate 25 (enter the interior of the groove 5);

[0050] In summary, the sliding door electrodes can be tested continuously at multiple stations by reciprocating in sequence, and the sliding door electrodes can be automatically sorted and transported according to the test results during the test, thereby improving the use effect of the equipment.

[0051] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
