[0022] like Figures 1 to 3 As shown, the roller short circuit testing device 100 of the present invention is used to detect whether the pole group 200 is short-circuited.

[0023] The electrode group 200 includes a diaphragm 202 and a plurality of spaced electrode pieces 201, wherein the electrode pieces 201 include a polar body 203 and a polar ear 204 connected to each other, the diaphragm 202 covers both sides of the polar body 203, and the polar ear 204 protrudes from the diaphragm 202. The width of the polar ear 204 along the transmission direction of the electrode group 200 is smaller than the width of the polar body 203.

[0024] The roller short-circuit testing device 100 includes a conductive lower roller 1, a conductive upper roller 2 for holding the pole group 200 against the conductive lower roller 1, a driving cylinder 3 connected to the conductive upper roller 2, an insulating block 4 arranged at one end of the conductive lower roller 1, a conductive sheet 5 electrically connected to the pole ear 204 on the insulating block 4, a driving component 6 for driving the conductive lower roller 1 to rotate so as to drive the pole group 200 to move, a conductive core shaft 7 coaxially connected to the conductive lower roller 1 and inserted into the conductive lower roller 1, an electric slip ring 8 arranged at one end of the conductive core shaft 7, a guide sheet 9 arranged close to the insulating block 4, and a short-circuit tester 10.

[0025] The driving assembly 6 includes a motor 61, a reducer 62 connected to the motor 61, and a coupling 63 connecting the reducer 62 and the conductive lower roller 1. The driving assembly 6 can drive the conductive lower roller 1 to rotate, and because the conductive upper roller 2 presses the pole group 200 against the conductive lower roller 1, the conductive lower roller 1 can drive the pole group 200 to move when it rotates.

[0026] The conductive core shaft 7 is electrically connected to the conductive lower roller 1 , the electric slip ring 8 is electrically connected to the conductive core shaft 7 , and the electric slip ring 8 is configured to be electrically connected to the short circuit tester 10 .

[0027] The driving cylinder 3 is used to drive the conductive upper roller 2 to move toward or away from the conductive lower roller 1 , so as to hold the pole group 200 against the conductive lower roller 1 .

[0028] The conductive upper roller 2 includes a shaft 21 and a supporting portion 22 made of a conductive adhesive material and arranged on the surface of the shaft 21. The supporting portion 22 is used to be electrically connected to the short circuit tester 10. The supporting portion 22 is made of a conductive adhesive material, which can play a better pressing role on the one hand and a conductive role on the other hand.

[0029] The short circuit tester 10 includes a positive electrode and a negative electrode, one of which is electrically connected to the conductive upper roller 2 and the conductive lower roller 1 , and the other is electrically connected to the conductive sheet 5 .

[0030] When the diaphragm 202 is damaged, the pole body 203 corresponding to the damaged part is electrically connected to the conductive upper roller 2 or the conductive lower roller 1. Since the pole ear 204 is electrically connected to the conductive sheet 5, the short circuit tester 10 can detect data and further determine whether there is damage.

[0031] The insulating block 4 is fixedly arranged on the conductive lower roller 1 and can rotate along with the rotation of the conductive lower roller 1 .

[0032] The pole lug 204 is electrically connected to the conductive sheet 5 on the insulating block 4 after being guided by the guide sheet 9 .

[0033] In this embodiment, the number of the conductive sheets 5 is two, and they are spaced apart along the rotation direction of the insulating block 4. At any position where the conductive upper roller 2 and the conductive lower roller 1 abut against the electrode group 200, at least one conductive sheet 5 is electrically connected to the electrode lug 204. The conductive sheet 5 is connected to a driving member so that the position of the conductive sheet 5 relative to the insulating block 4 is adjustable, so as to facilitate the placement of the electrode group 200 and to accommodate electrode groups 200 of different thicknesses.

[0034] The driving member can drive the conductive sheet 5 to approach or move away from the

[0035] Of course, in other embodiments, a longer conductive sheet 5 may also be provided, which can also achieve the effect that when the conductive upper roller 2 and the conductive lower roller 1 abut against the pole body 203 , the conductive sheet 5 is connected to the pole ear 204 .

[0036] In this embodiment, the conductive sheet 5 is a copper sheet.

[0037] The use of the roller short circuit test device 100 of the utility model is as follows: the conductive upper roller 2 presses the pole group 200 against the conductive lower roller 1 under the action of the cylinder; the driving assembly 6 is started to drive the conductive lower roller 1 to rotate and drive the pole group 200 to drive; at this time, the conductive upper roller 2 and the conductive lower roller 1 press the diaphragm 202, the conductive sheet 5 is connected to the pole ear 204, and further connected to the short circuit tester 10, the conductive upper roller 2 is connected to the short circuit tester 10 through the conductive core shaft 7 and the electric slip ring 8, and the abutting part 22 of the conductive upper roller 2 is also electrically connected to one pole connected to the electric slip ring 8. If there is damage on either side of the diaphragm 202, the short circuit tester 10 can detect the electrical signal, and then determine that the pole piece 201 at the corresponding position is damaged.

[0038] The roller short-circuit test device 100 of the utility model can detect whether the diaphragm 202 of the pole piece 201 is damaged, thereby avoiding the problem of the entire pole group 200 being scrapped due to damage to the diaphragm 202. In addition, the roller short-circuit test device 100 can simultaneously detect the damage of the diaphragms 202 on both sides without adding additional structure space, thus saving more space.

[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
