[0002] At present, the main manufacturing method of lithium battery bare cells is the winding method. For the convenience of production and manufacturing, the electrode sheets of the cells used for winding usually need to be die-cut, and only the part of the metal foil that needs to pass current is retained. This part of the metal foil is the ear.
[0003] At present, in most lithium battery manufacturing enterprises, automated equipment is used to realize the glue pasting process of the positive and negative ears. Ear glue pasting can not only protect the solder joints between the ear and the connecting piece after the cover plate is welded, but also prevent the short circuit problem caused by the contact between the ear and the shell after the wound core enters the shell. However, the automatic glue pasting equipment lacks a detection device that can effectively identify and screen defective products of ear glue pasting. Since there are different models of lithium batteries, for different models of lithium batteries, defective products of ear glue pasting are mostly selected by manual visual inspection, and the detection accuracy is not enough, and misdetection may occur. In view of this, an ear detection device for lithium battery production is proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-4 , the present utility model provides a new technical solution: an ear detection device for lithium battery production, including a base 1, the upper surface of the base 1 is fixedly installed with a detection device housing 2, a slot 12 is opened on the upper surface of the detection device housing 2, and a chute 3 is opened on the outer surface of the detection device housing 2;
[0022] A fixing mechanism is arranged on the detection device housing 2 and is used for performing ear detection on the fixation of the lithium battery. The fixing mechanism includes two first springs 4, and the two first springs 4 are fixedly installed in the inner wall of the chute 3.
[0023] Furthermore, the fixing mechanism further includes two first fixing plates 5 and a collar 6. The two first fixing plates 5 are fixedly installed at the upper ends of the first springs 4, and the upper surfaces of the two first fixing plates 5 are both inclined. The collar 6 is fixedly installed on the outer surfaces of the two first fixing plates 5, and the collar 6 is slidably connected to the chute 3.
[0024] Furthermore, two grooves 7 are opened in the inner wall of the chute 3, and two second fixing plates 8 are respectively slidably sleeved in the inner walls of the two grooves 7. The lower surfaces of the two second fixing plates 8 are both inclined.
[0025] Furthermore, the fixing mechanism further includes four second springs 9, and the four second springs 9 are respectively fixedly installed in the inner walls of the two grooves 7, and the opposite ends of the four second springs 9 are fixedly connected to the two second fixing plates 8.
[0026] Furthermore, the fixing mechanism further includes four fixing rods 10 and two clamping plates 13. The four fixing rods 10 are respectively fixedly installed on the opposite surfaces of the two second fixing plates 8, and the four fixing rods 10 are respectively slidably sleeved in the vertical plates on the opposite sides of the detection device housing 2. The two clamping plates 13 are respectively fixedly installed at the opposite ends of the four fixing rods 10.
[0027] Further, a detection power-on board 14 is fixedly installed on the inner wall of the detection device housing 2, and the detection power-on board 14 is electrically connected to the detection lamp 11. When the ear detection device for lithium battery production is in use, by applying a downward thrust to the collar 6, it slides downward in the chute 3. At the same time, the collar 6 drives the two first fixing plates 5 fixedly sleeved on the inner surface to move downward. At the same time, the two first fixing plates 5 apply pressure to the two first springs 4 fixedly installed on the lower surface, causing them to contract. At this time, the lithium battery is inserted into the slot 12 opened on the upper surface of the detection device housing 2, and the ears of the lithium battery are connected to the detection power-on board. At this time, no downward thrust is applied to the collar 6, and the two first springs 4 are no longer stressed. At this time, the two first springs 4 expand, and the two first springs 4 apply an upward thrust to the two first fixing plates 5 fixedly installed at the upper ends, causing the inclined surfaces of the two first fixing plates 5 to impact the inclined surfaces of the two second fixing plates 8, causing the two second fixing plates 8 to move towards the opposite surfaces. At the same time, the two second fixing plates 8 apply pressure to the four second springs 9 fixedly installed on the opposite surfaces, causing them to contract. At the same time, the two second fixing plates 8 apply a thrust towards the opposite surfaces to the four fixing rods 10 fixedly installed on the opposite surfaces, causing them to slide towards the opposite surfaces in the inner walls of the vertical plates on the opposite sides of the detection device housing 2. At the same time, the four fixing rods 10 apply a thrust towards the opposite surfaces to the two clamping plates 13 fixedly installed on the opposite surfaces, causing them to move towards the opposite surfaces and fit against the outer surface of the lithium battery for clamping and fixing for detection. When the ears are in good condition, the detection power-on board 14 will be powered on, and the detection lamp 11 will be lit through the electrical connection. In the case of poor contact of the ears, the detection lamp 11 cannot be lit. The ear detection device for lithium battery production can fix lithium batteries of different models through the clamping and fixing method for subsequent detection. The operation is simple, and the lithium battery can be fixed quickly, which is more convenient. Moreover, the ear detection device for lithium battery production can quickly judge whether the contact of the lithium battery ears is poor by observing whether the detection lamp is lit through the electrical connection between the detection power-on board and the detection lamp. Compared with the method of human eye observation, the detection error is reduced, and the detection accuracy is improved.
[0028] Working principle: When the ear detection device for lithium battery production is in use, by applying a downward thrust to the collar 6, it slides downward in the chute 3. At the same time, the collar 6 drives the two first fixing plates 5 fixedly sleeved on the inner surface to move downward. At the same time, the two first fixing plates 5 apply pressure to the two first springs 4 fixedly installed on the lower surface, causing them to contract. At this time, the lithium battery is inserted into the slot 12 opened on the upper surface of the detection device housing 2, and the ears on the lithium battery are connected to the detection power-on plate. At this time, no downward thrust is applied to the collar 6, and the two first springs 4 are no longer stressed. At this time, the two first springs 4 expand, and the two first springs 4 apply an upward thrust to the two first fixing plates 5 fixedly installed at the upper ends, causing the inclined surfaces of the two first fixing plates 5 to impact the inclined surfaces of the two second fixing plates 8, causing the two second fixing plates 8 to move towards the opposite surfaces. At the same time, the two second fixing plates 8 apply pressure to the four second springs 9 fixedly installed on the opposite surfaces, causing them to contract. At the same time, the two second fixing plates 8 apply a thrust towards the opposite surfaces to the four fixing rods 10 fixedly installed on the opposite surfaces, causing them to slide towards the opposite surfaces in the inner walls of the vertical plates on the opposite sides of the detection device housing 2. At the same time, the four fixing rods 10 apply a thrust towards the opposite surfaces to the two clamping plates 13 fixedly installed on the opposite surfaces, causing them to move towards the opposite surfaces and fit against the outer surface of the lithium battery for clamping and fixing for detection. When the ears are in good condition, the detection power-on plate 14 will be powered on, and the detection lamp 11 will be lit through the electrical connection with it. In the case of poor contact of the ears, the detection lamp 11 cannot be lit.
