Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a capping device for new energy lithium batteries. Background Technology

[0002] A new energy lithium battery capping device is a device used to press a battery cover into the battery casing. It is commonly used in the lithium battery production process. The main purpose of this device is to ensure the sealing and stability between the battery cover and the battery casing, so as to prevent the leakage of electrolyte inside the battery and protect the performance and safety of the battery.

[0003] During the battery capping process, the battery cap must be placed precisely on top of the battery. If workers perform this step for a long time, visual fatigue can easily lead to increased deviation in the placement of the cap, resulting in a decline in product quality.

[0004] Therefore, in response to the situation where workers are prone to visual fatigue during long-term battery capping operations, leading to increased deviations in the placement of the caps and inaccurate alignment between the battery and the cap, resulting in a decline in product quality, a new energy lithium battery capping device can be designed to reduce its operating costs and achieve energy-saving and environmentally friendly effects. Utility Model Content

[0005] To address the issue that during the battery capping process, where the battery cap needs to be precisely placed on top of the battery, prolonged exposure to this step can lead to visual fatigue, resulting in increased misalignment of the cap and consequently, a decline in product quality.

[0006] The technical solution of this utility model is as follows: a new energy lithium battery capping device, including an upper shell and a pressure plate. A cover plate reserved groove is opened on one side of the upper shell. A rotating paddle is rotatably connected to the lower end of the upper shell. A retaining ring is fixed to the outer edge of the upper surface of the rotating paddle. A material picking groove is opened on one side of the upper surface of the rotating paddle. A hydraulic cylinder is fixedly connected inside the upper shell. A pressure plate is fixedly connected to the lower end of the hydraulic cylinder. A pressure ring is slidably connected to the outer side of the pressure plate. A fixed plate is rotatably connected to the lower end of the rotating paddle. A chamfered material discharge groove is opened at the rear end of the upper surface of the fixed plate.

[0007] Preferably, the fixing plate can be replaced according to the size of the battery so that the lower port diameter of the chamfered discharge slot on the device corresponds to the size of the battery. Then, the cover plates of multiple batteries are vertically stacked in the cover plate reserved slot. When the material picking slot comes to the bottom of the cover plate reserved slot as the rotating paddle rotates, the bottom cover plate will fall into the material picking slot and be pushed by the rotating paddle to the chamfered discharge slot, and fall from the chamfered discharge slot to the top of the battery. At the same time, the rotating paddle stops rotating, and the hydraulic cylinder pushes the pressure plate downward. At this time, the pressure ring, which droops due to its own gravity, will contact the outer ring of the chamfered discharge slot before the pressure plate, so as to push any cover plates that may be stuck in the chamfered discharge slot toward the middle of the chamfered discharge slot. Then the pressure plate contacts the cover plate and presses the cover plate downward to press the cover plate firmly on the top of the battery. Then the hydraulic cylinder retracts the pressure plate and the pressure ring, while the rotating paddle continues to rotate.

[0008] Preferably, the retaining ring is located inside the upper housing and is rotatably connected to the upper housing, and the pressure plate is located at the top of the chamfered discharge chute.

[0009] Preferably, the lower end of the fixed plate is provided with a lower housing, and the upper end of the lower housing is rotatably connected to a lever, which has four slots evenly provided.

[0010] Preferably, a positioning block is slidably connected to the lower end of the lever, a driven gear shaft is fixedly connected to the lower end of the positioning block, and the driven gear shaft is rotatably connected to the lower housing. A driven gear is fixedly connected to the middle of the upper surface of the rotating lever.

[0011] Preferably, a drive gear meshes with one side of both the driven gear shaft and the driven gear, and a servo motor is mounted on each drive gear. The upper servo motor is mounted inside the upper housing, while the lower servo motor is mounted inside the lower housing.

[0012] Preferably, a discharge chute is provided at the lower end of one side of the lower housing, and the discharge chute is located at the lower end of the pusher block.

[0013] Preferably, four bolt sleeves are fixed to the lower end of the outer side of the upper shell, the outer side of the fixing plate, and the upper end of the outer side of the lower shell, and the bolt sleeves at different heights are aligned with each other and screwed into the bolt together.

[0014] The beneficial effects of this utility model are:

[0015] By setting a rotating paddle, pressure plate, and pressure ring, the fixed plate can be replaced according to the size of the battery, so that the lower port diameter of the chamfered discharge slot on the device corresponds to the size of the battery. Then, the covers of multiple batteries are vertically stacked in the pre-reserved slot of the cover. When the material receiving slot is directly below the pre-reserved slot of the cover as the rotating paddle rotates, the bottom cover will fall into the material receiving slot and be pushed by the rotating paddle towards the chamfered discharge slot, and fall from the chamfered discharge slot onto the top of the battery. At the same time, the rotating paddle stops rotating, and the hydraulic cylinder pushes the pressure plate downward. At this time, the battery falls due to its own gravity. The vertical pressure ring contacts the outer ring of the chamfered discharge groove before the pressure plate, pushing any cover plates that may be stuck in the chamfered discharge groove toward the center of the groove. Then, the pressure plate contacts the cover plate and presses it down to firmly press the cover plate onto the upper end of the battery. Subsequently, the hydraulic cylinder retracts the pressure plate and pressure ring, while the rotating paddle continues to rotate. This allows the battery capping operation to be less demanding on the worker's eyesight, and the device can be adjusted according to the size of the battery, thereby reducing the impact of the worker's visual condition on product quality and increasing the flexibility of the device during use.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment of a new energy lithium battery capping device, including an upper housing 1 and a pressure plate 7. A cover plate pre-reserved groove 2 is provided on one side of the upper housing 1. A rotating paddle 3 is rotatably connected to the lower end of the upper housing 1. A retaining ring 4 is fixedly connected to the outer edge of the upper surface of the rotating paddle 3. A material-receiving groove 5 is provided on one side of the upper surface of the rotating paddle 3. A hydraulic cylinder 6 is fixedly connected inside the upper housing 1. The pressure plate 7 is fixedly connected to the lower end of the hydraulic cylinder 6. A pressure ring 8 is slidably connected to the outer side of the pressure plate 7. A fixed plate 9 is rotatably connected to the lower end of the rotating paddle 3. A chamfered discharge groove 10 is provided at the rear end of the upper surface of the fixed plate 9. The fixed plate 9 can be replaced according to the size of the battery so that the lower port diameter of the chamfered discharge groove 10 on the device corresponds to the size of the battery. Then, multiple battery caps are applied. The plates are stacked vertically in the pre-reserved slot 2 of the cover plate. When the material picking slot 5 comes to the bottom of the pre-reserved slot 2 of the cover plate as the rotating paddle 3 rotates, the bottom cover plate will fall into the material picking slot 5 and be pushed by the rotating paddle 3 to the chamfered discharge slot 10, and fall from the chamfered discharge slot 10 to the top of the battery. At the same time, the rotating paddle 3 stops rotating, and the hydraulic cylinder 6 pushes the pressure plate 7 downward. At this time, the pressure ring 8, which is drooping due to its own weight, will contact the outer ring of the chamfered discharge slot 10 before the pressure plate 7, so as to push any cover plates that may be stuck in the chamfered discharge slot 10 towards the middle of the chamfered discharge slot 10. Then the pressure plate 7 contacts the cover plate and presses the cover plate downward to press the cover plate firmly on the top of the battery. Then the hydraulic cylinder 6 retracts the pressure plate 7 and the pressure ring 8, while the rotating paddle 3 continues to rotate.

[0025] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6In this embodiment, the retaining ring 4 is disposed inside the upper housing 1 and is rotatably connected to the upper housing 1. The pressure plate 7 is disposed at the upper end of the chamfered discharge groove 10. The retaining ring 4 allows the rotating paddle 3 to be rotatably connected to the upper housing 1 while simultaneously allowing the rotating paddle 3 to be hung on the lower end of the upper housing 1. The lower end of the fixed plate 9 is provided with the lower housing 11. The upper end of the lower housing 11 is rotatably connected to the inside of the lower housing 11. The paddle 12 has four slots 13 evenly distributed on it. The lower end of the paddle 12 is slidably connected to the positioning block 14. The lower end of the positioning block 14 is slidably connected to the positioning block 14. A driven gear shaft 15 is fixedly connected and rotatably connected to the lower housing 11. A driven gear 16 is fixedly connected to the middle of the upper end face of the rotating paddle 3. The sliding connection between the paddle block 12 and the positioning block 14 allows the operator to replace the paddle block 12 so that the diameter of the slot 13 inside the device corresponds to the size of the battery. A drive gear 17 meshes with one side of both the driven gear shaft 15 and the driven gear 16. A servo motor 18 is mounted on each of the drive gears 17. The upper servo motor 18 is installed inside the upper housing 1, while the lower servo motor 18 is installed inside the lower housing 1. The servo motor 18 is installed inside the lower housing 11. The servo motor 18 can drive the driven gear shaft 15, positioning block 14 and slot 13 to rotate via the drive gear 17, or drive the driven gear 16 and rotating paddle 3 to rotate via the drive gear 17. The rotation speed of the rotating paddle 3 is four times that of the paddle block 12. A discharge chute 19 is provided at the lower end of one side of the lower housing 11, and the discharge chute 19 is located at the lower end of the paddle block 12. After the battery is placed in the slot 13, it will be displaced to the area directly below the chamfered discharge chute 10 as the paddle block 12 rotates. During the capping process, the lever 12 pauses its rotation. The capped battery continues to move as the lever 12 rotates and slides out of the device through the unloading chute 19 to complete the unloading. Four bolt sleeves 20 are fixed to the lower end of the outer side of the upper housing 1, the outer side of the fixing plate 9, and the upper end of the outer side of the lower housing 11. The bolt sleeves 20 at different heights are aligned vertically and screwed into the bolts. After the bolt sleeves 20 are aligned vertically and screwed into the bolts, the upper housing 1, the fixing plate 9, and the lower housing 11 can be assembled and fixed together.

[0026] During use, the fixed plate 9 can be replaced according to the size of the battery so that the lower port diameter of the chamfered discharge groove 10 on the device corresponds to the size of the battery. In addition, the sliding connection between the lever 12 and the positioning block 14 allows the operator to replace the lever 12 so that the diameter of the slot 13 in the device corresponds to the size of the battery.

[0027] Then, the cover plates of multiple batteries are vertically stacked in the cover plate reserved slot 2. When the material picking slot 5 comes to the bottom of the cover plate reserved slot 2 as the rotating paddle 3 rotates, the bottom cover plate will fall into the material picking slot 5 and be pushed by the rotating paddle 3 to the chamfered discharge slot 10, and fall from the chamfered discharge slot 10 to the top of the battery. At the same time, the rotating paddle 3 stops rotating, and the hydraulic cylinder 6 pushes the pressure plate 7 downward. At this time, the pressure ring 8, which is drooping due to its own gravity, will contact the outer ring of the chamfered discharge slot 10 before the pressure plate 7, so as to push the cover plate that may be stuck in the chamfered discharge slot 10 towards the middle of the chamfered discharge slot 10. Then the pressure plate 7 contacts the cover plate and presses the cover plate downward to press the cover plate firmly on the top of the battery. Then the hydraulic cylinder 6 retracts the pressure plate 7 and the pressure ring 8, while the rotating paddle 3 continues to rotate.

[0028] The rotating paddle 3 and the paddle block 12 rotate and stop at the same time, but the rotation speed of the rotating paddle 3 is four times that of the paddle block 12. After the battery is placed into the slot 13, it will move to the bottom of the chamfered discharge trough 10 to receive the cap as the paddle block 12 rotates. During the capping process, the paddle block 12 stops rotating. The capped battery will continue to move as the paddle block 12 rotates and slide out of the device through the unloading chute 19 to complete the unloading.

[0029] Through the above steps, by setting the rotating paddle 3, pressure plate 7, and pressure ring 8, the fixing plate 9 can be replaced according to the size of the battery, so that the lower port diameter of the chamfered discharge groove 10 on the device corresponds to the size of the battery. Then, the cover plates of multiple batteries are vertically stacked in the cover plate reserved groove 2. When the material picking groove 5 moves to the bottom of the cover plate reserved groove 2 as the rotating paddle 3 rotates, the bottom cover plate will fall into the material picking groove 5 and be pushed by the rotating paddle 3 to the chamfered discharge groove 10, and fall from the chamfered discharge groove 10 onto the top of the battery. At the same time, the rotating paddle 3 stops rotating, and the hydraulic cylinder 6 pushes the pressure plate 7 downward. At this time, due to the self- The pressure ring 8, which hangs down under the weight of the battery, will contact the outer ring of the chamfered discharge groove 10 before the pressure plate 7, so as to push the cover plate that may be stuck in the chamfered discharge groove 10 towards the center of the chamfered discharge groove 10. Then the pressure plate 7 will contact the cover plate and press the cover plate down to press the cover plate firmly on the upper end of the battery. Then the hydraulic cylinder 6 will retract the pressure plate 7 and the pressure ring 8, while the rotating paddle 3 will continue to rotate. This way, the battery capping operation does not require too much eye strain from the worker, and the device can be adjusted according to the size of the battery, thereby reducing the impact of the worker's vision on product quality and increasing the flexibility of the device during use.
