[0027] A positive probe 14 and a negative probe 15 are vertically fixedly installed on the upper surface of the lower plug plate 7. The positive probe 14 and the negative probe 15 are symmetrically arranged front to back. In addition, the upper end diameters of the positive probe 14 and the negative probe 15 are smaller than the lower end diameters, so that the positive probe 14 and the negative probe 15 can be smoothly plugged into and separated from the positioning holes on the pole ears.
[0028] Specifically, the upper plug board 5 is evenly provided with upper slots, and an upper combing plate is formed between the upper slots; the lower plug board 7 is evenly provided with lower slots, and a lower combing plate is formed between the lower slots; when the upper combing plate is plugged into the lower slots, the lower combing plate is plugged into the upper slots. At this time, the upper plug board 5 and the lower plug board 7 form a complete storage board, which can also be used separately.
[0029] Specifically, the clamp includes a clamping jaw 2 and a positioning piece 16. The clamping jaw 2 is fixedly assembled with the platform 3. The clamping jaw 2 is provided with two translational jaws that move in opposite directions (toward each other or away from each other). The clamping jaw 2 is an existing component having structures such as a housing, a cylinder, and opposite transmission connecting rods. The translational jaw is vertically installed with a positioning piece 16, and the positioning piece 16 extends into the feed port 17; the clamping jaw 2 moves the positioning piece 16 on the translational jaw in opposite directions, so as to tighten the pole ears on both sides, thereby aligning the stacked pole pieces and the insulating diaphragm. At this time, the positioning hole will also be in full contact with the positive electrode probe 14 and the negative electrode probe 15.
[0030] The upper plug board 5, the lower plug board 7 and the positioning piece 16 are all made of insulating materials to avoid affecting the short circuit detection work.

[0032] Furthermore, a linear bearing 19 is fixedly installed in the guide hole, and the light rod 8 is slidably assembled in the linear bearing 19; through the provision of the linear bearing 19, the friction between the guide hole and the light rod 8 can be reduced, making the lifting and lowering action of the substrate 10 smoother.

[0034] Furthermore, the first movable module 1 is preferably an electric screw module, which is an existing device with a housing, a servo motor, a screw, a screw nut and a slide, etc., and has high positioning accuracy; the second movable module 18 is preferably a rodless cylinder, which is an existing device that is directly or indirectly connected to an external actuator by a piston, and occupies a small installation space; no matter which mobile device is used, as long as it can meet the moving accuracy and service life, it will not affect the implementation of the present device.
[0035] The working principle of this embodiment:
[0036] In the initial state, the push cylinder 4 translates the upper plug plate 5 to the left, and the first movable module 1 lifts the lower plug plate 7. At this time, the upper plug plate 5 and the lower plug plate 7 are plugged into a complete storage plate, and the clamping claw 2 drives the two positioning plates 16 to be located close to each other; the pole pieces and insulating diaphragms produced by the cutting and stacking machine are stacked from top to bottom on the storage plate, and the positioning holes on the pole ears are respectively plugged into the positive probe 14 and the negative probe 15 to complete the preliminary positioning.
[0037] When the photoelectric gate component in the cutting and stacking machine monitors that the number of stacked pole pieces reaches the set value, the jaws 2 in the clamp drive the two positioning pieces 16 to be located at positions far away from each other, abutting the pole ears to achieve the purpose of pole piece alignment, and the positioning holes can also be fully in contact with the positive probe 14 and the negative probe 15 respectively. At this time, the positive probe 14 and the negative probe 15 are energized for short-circuit detection, and the clamp is reset after the detection is completed.
[0038] When the inspection is qualified, the push cylinder 4 translates the upper plug plate 5 to the right, the first movable module 1 first moves the lower plug plate 7 downward, and then moves the lower plug plate 7 to the right through the second movable module 18, and the qualified electrode piece is sent to the gluing device in cooperation with the conveyor for the next processing step. After completion, the lower plug plate 7 is reconnected and reset with the upper plug plate 5; after the electrode piece completely passes downward through the feed port 17, the push cylinder 4 translates the upper plug plate 5 to the left and resets it, and can continue to receive the processed electrode piece.
[0039] When the test fails, that is, the insulating diaphragm is damaged, resulting in contact between the positive and negative electrodes, and the positive probe 14 and the negative probe 15 will also be short-circuited. Therefore, the PLC controller in the cutting and stacking machine can record the short-circuit position in time to form a system record, providing data for subsequent processing. The unqualified electrode will also be sent to the processing table along with the lower plug-in board 7 and the conveyor. After completion, the lower plug-in board 7 will be reconnected and reset with the upper plug-in board 5.
[0040] Such a cycle can quickly realize the storage, short circuit detection and transportation of electrodes, with better working continuity and higher detection accuracy.
