Description

Technical Field

[0001] The utility model belongs to the technical field of battery production equipment, and particularly relates to a hob lubrication device and a grooving system. Background Art

[0002] In the field of modern energy storage technology, cylindrical batteries have attracted much attention due to their high energy density, good cycle performance, and wide application fields. For the production of cylindrical batteries, multiple processes work together to ensure that the batteries meet the established performance standards. Among them, the cylindrical battery grooving process is a crucial technological link. This process is not only crucial for ensuring a good connection between the internal structure and the external shell of the battery but also directly affects the formation of the sealing effect between the battery cover and the shell, thus relating to the overall safety performance and service life of the battery.

[0003] The cylindrical battery grooving process uses a grooving machine and its supporting fixtures. The rotating hob in the grooving machine precisely processes a grooving with a specific shape and depth that meets the design requirements on the surface of the positive electrode shell of the cylindrical battery. The grooving enhances the sealing between the battery cover and the shell, effectively preventing the leakage of electrolyte and significantly improving the safety performance and service life of the battery. As one of the key devices in this process, the performance of the grooving machine directly affects the processing quality and production efficiency of the grooves on the battery shell. In the prior art, a cylindrical battery grooving device is provided. The cylindrical battery grooving device includes a material support, a pressing mechanism, a grooving mechanism, and a driving mechanism, wherein the grooving mechanism includes a hob. When grooving a cylindrical battery, the driving mechanism drives the pressing member to rotate around the vertical axis and drives the battery to rotate, enabling the hob to perform grooving processing around the battery. Thus, it can be seen that when grooving a cylindrical battery, the hob, as the core component of the grooving machine, directly participates in the cutting processing of the groove. However, the long-term and high-frequency contact between the hob and the battery shell will cause wear to the hob. This wear will not only affect the accuracy and consistency of the grooving but also shorten the service life of the hob and increase production costs. Therefore, during the use of the hob, a good lubrication state should be maintained. Appropriate lubrication can reduce friction and wear and extend the service life of the hob. Currently, lubricating oil is often added to the grooving tool manually at regular intervals. This method not only needs to be carried out when the grooving machine is stopped but also often results in serious wear of the hob due to untimely addition of lubricating oil. Manual operation may also introduce pollution due to human factors, affecting the cleanliness and overall quality of the battery shell.

[0004] Due to the many drawbacks of the above-mentioned manual lubrication method, a device that can automatically, continuously, and stably lubricate the hob is proposed to reduce the friction between the hob and the battery shell during operation. Summary of the Utility Model

[0027] Embodiment 1:

[0028] See attached Figures 1 - 2 。 Figure 1 The specific structure of the hob lubrication device of the present utility model is shown. The hob lubrication device of the present utility model includes a soaking mechanism 1, an oil supply mechanism 2, and an oil control mechanism 3. The soaking mechanism 1 has a groove 5, and the groove 5 wraps a part of the hob to facilitate soaking the hob. The oil supply mechanism 2 includes an oil storage tank 7, and is used to supply oil to the groove of the soaking mechanism through a diversion member 8. The oil control mechanism 3 replenishes oil to the oil supply mechanism 2 by opening a storage part 10 communicating with the outside. As the groove 5 on the soaking mechanism 1 lubricates the hob, the lubricating oil in the oil storage tank 7 of the oil supply mechanism 2 will decrease. At this time, the oil control mechanism 3 will open the storage part 10 communicating with the outside to replenish oil to the oil supply mechanism 2.

[0029] Specifically, the soaking mechanism 1 can be a housing 23. One side of the housing 23 is provided with a groove 5, and a side wall part of the groove 5 forms an oil outlet part 4. The oil storage tank 7 of the oil supply mechanism 2 is communicated with the oil outlet part 4 through a diversion member 8. The hob is located at the position of the oil outlet part 4, and the lubricating oil in the oil supply mechanism 2 flows out from the oil outlet part 4 to lubricate the hob located at the position of the oil outlet part 4.

[0030] Specifically, the oil outlet part 4 includes an oil outlet hole 6 and a soaking layer 9. A plurality of oil outlet holes 6 are formed in the side walls of the groove 5. The oil outlet holes 6 are communicated with the oil supply mechanism 2. A soaking layer 9 is arranged on the side wall of the groove 5. The soaking layer 9 can be a water-absorbing sponge or a water-absorbing non-woven fabric. The soaking layer 9 covers the side wall of the groove 5 and covers all the oil outlet holes 6. When the hob lubrication device is installed on the grooving machine, part of the hob is located in the groove 5. The lubricating oil flowing into the oil supply mechanism 2 flows out through the oil outlet holes 6 of the groove 5 and soaks the entire soaking layer 9. After the hob contacts the soaking layer 9, the lubricating oil in the soaking layer 9 lubricates the upper and lower surfaces of the hob stably and evenly at the same time.

[0031] Specifically, the oil supply mechanism 2 includes a plurality of oil storage tanks 7. The oil storage tanks 7 are arranged in the housing 23 and are located at the side walls of the groove 5, and are arranged in a stepped manner from top to bottom. As shown in the attached Figure 1 figure, three oil storage tanks 7 are provided. The first oil storage tank 7 is fixed on the topmost side wall of the groove 5. One ends of the second oil storage tank 7 and the third oil storage tank 7 are both fixed on the middle side wall of the groove 5. The three oil storage tanks 7 are arranged in a stepped manner from top to bottom. In this way, when the first oil storage tank 7 is filled with lubricating oil, the lubricating oil will overflow from the end far away from the side wall of the groove 5 and flow into the second oil storage tank 7. Similarly, when the second oil storage tank 7 is filled with lubricating oil, the lubricating oil will flow into the third oil storage tank 7. When the second oil storage tank 7 is filled with lubricating oil, the lubricating oil will flow into the bottom inside the housing 23.

[0032] Specifically, a flow guiding member 8 is provided between the adjacent oil outlet holes 6 of the oil storage tank 7 and between the bottom of the housing 23 and the oil outlet holes 6 on the bottom side wall of the groove 5. The flow guiding member 8 can be a soaking strip made of sponge or non-woven fabric. The lubricating oil moves to the oil outlet holes 6 from the oil storage tank 7 and the bottom of the housing 23 by means of soaking.

[0033] Specifically, the oil control mechanism 3 includes a stopper 11 and a driving assembly 12. The outlet of the oil storage part 10 is located at the bottom of the oil storage part 10 and is above the oil supply mechanism 2. When the oil control mechanism 3 is arranged on the outer side wall of the housing 23, as shown in the attached Figure 1 figure, a hole is formed in the housing 23 corresponding to the outlet of the oil storage part 10. In this way, the lubricating oil can flow out through the outlet of the oil storage part 10 under the action of gravity and flow into the oil supply mechanism 2. A stopper 11 is provided at the outlet of the oil storage part 10. The stopper 11 closes the oil storage part 10 to prevent the lubricating oil from flowing out. The driving assembly 12 is used to drive the stopper 11 to move away from or close to the outlet of the oil storage part 10 to open or close the outlet of the oil storage part 10 and control the outflow of the lubricating oil. Attached Figure 1The oil control mechanism 3 shown in the figure is provided on the outer side wall of the outer shell 23. It can be understood that the oil control mechanism 3 can be provided inside or outside the outer shell 23, as long as the lubricating oil of the oil control mechanism 3 can enter the oil supply mechanism 2.

[0034] Specifically, the oil control mechanism 3 further includes a guide frame 13. The guide frame 13 is fixed to one side of the oil storage part 10. The stopper 11 is movably arranged in the guide frame 13. Guide openings 14 are provided at corresponding positions at both ends of the guide frame 13. Both ends of the stopper 11 pass through the guide openings 14 at both ends of the guide frame 13 and extend beyond both ends of the guide frame 13. The stopper 11 can slide back and forth in the guide frame 13 along the direction of the guide opening 14. An opening is provided on the side wall of the oil storage part 10 at a position corresponding to the guide opening 14, and a receiving cavity corresponding to the opening is provided on the side surface opposite to the opening. One end of the stopper 11 passes through the guide opening 14, inserts into the oil storage part 10 from the opening of the oil storage part 10, and enters the corresponding receiving cavity to block the outlet of the oil storage part 10 and prevent the lubricating oil from flowing out.

[0035] Specifically, the driving assembly 12 includes a gravity block 15, a fixed pulley 16, a connecting rope 17 and an elastic member 18. A fixed pulley 16 is provided on the side of the guide frame 13 away from the oil storage part 10. The fixed pulley 16 can be fixed to the outer shell 23 through a bracket. The other end of the stopper 11 is connected with a connecting rope 17. The connecting rope 17 bypasses the fixed pulley 16 and is connected with a gravity ball inside the outer shell 23. The gravity ball is located at the bottom of the outer shell 23 and contacts the lubricating oil. A first limiting block 19 perpendicular to the stopper 11 is provided at one end of the stopper 11 close to the oil storage part 10, and a second limiting block 20 perpendicular to the stopper 11 is provided at the other end. The first limiting block 19 and the second limiting block 20 are respectively located inside and outside the guide frame 13 and move with the movement of the stopper 11. An elastic member 18 is provided between the side surface of the first limiting block 19 away from the oil storage part 10 and the side wall of the guide frame 13. The elastic member 18 can be a spring. When the stopper 11 moves away from the outlet of the oil storage part 10, the first limiting block 19 will move with the stopper 11 and compress the spring. When the spring returns to its original position, the first limiting block 19 drives the stopper 11 to approach the outlet of the oil storage part 10 under the action of the spring and finally closes the outlet.

[0036] When there is enough lubricating oil in the oil supply mechanism 2 inside the outer shell 23 and at the bottom of the outer shell 23, as shown in the appendix Figure 1As shown, the lubricating oil of the oil supply mechanism 2 will lubricate the hob stably and continuously through the diversion member 8 and the infiltration layer 9. At this time, the stopper 11 blocks the outlet of the oil storage part 10 to close the outlet, and the lubricating oil will not flow out of the oil storage part 10. At this time, the lubricating oil at the bottom of the housing 23 will give buoyancy to the gravity block 15, and the gravity block 15 floats on the lubricating oil, and the connecting rope 17 is in a slack state. With the continuous lubrication of the hob, the lubricating oil in the oil supply mechanism 2 and at the bottom of the housing 23 will gradually decrease. The gravity block 15 will move downward under the action of gravity as the lubricating oil decreases, and pull the stopper 11 through the connecting rope 17, causing the stopper 11 to move away from the outlet of the oil storage part 10. At the same time, the first limit block 19 compresses the elastic member 18. When the lubricating oil at the bottom of the housing 23 decreases to a certain amount, as shown in the appendix Figure 2 As shown, the outlet of the oil storage part 10 is opened, and the lubricating oil flows into the oil supply mechanism 2 through the oil storage part 10 under the action of gravity. When the oil supply mechanism 2 is filled with lubricating oil, the lubricating oil will flow into the bottom of the housing 23. The lubricating oil at the bottom of the housing 23 gradually increases, and the gravity block 15 moves upward accordingly. The connecting rope 17 gradually becomes slack, and the pulling force on the stopper 11 is released. The elastic member 18 gradually resumes its original state. Under the action of the elastic member 18, the stopper 11 moves closer to the outlet of the oil storage part 10, inserts into the accommodating cavity through the opening on the side wall of the oil storage part 10, and finally enters the corresponding accommodating cavity to block the outlet of the oil storage part 10, thereby stopping adding lubricating oil into the housing 23. Thus, as the hob is lubricated, the lubricating oil in the housing 23 decreases, and this hob lubrication device can automatically add lubricating oil into the oil supply mechanism 2, continuously and stably provide lubricating oil for the hob, keep the hob lubricated for a long time, reduce the friction between the hob and the battery housing during the operation of the hob, reduce the wear on the hob, and extend the service life of the hob.

[0037] Specifically, a second limit block 20 is provided at the other end of the stopper 11. The second limit block 20 is perpendicular to the stopper 11 and is located outside the guide frame 13. The second limit block 20 can be used to limit the displacement amount of the stopper 11 under the action of the elastic member 18.

[0038] Embodiment 2:

[0039] See the appendix Figure 3 . Figure 3 shows a schematic diagram of the position of the hob lubrication device of the present utility model, the grooving machine, and the battery housing 21. A grooving system includes a grooving machine and the hob lubrication device of Embodiment 1. The hob lubrication device is assembled on the grooving machine, so that the hob 22 of the grooving machine is partially located in the groove 5 of the hob lubrication device. When the grooving machine is working, the battery housing 21 is fixed on a matching fixture, and the fixture drives the battery housing 21 close to the hob 22 to groove the corresponding position of the battery housing 21. When the grooving machine is working, lubricating oil is added to the oil storage part 10, and the hob lubrication device will lubricate the hob 22 stably and continuously.
