Description

Technical Field

[0001] This invention relates to the technical field of lithium battery production equipment, and in particular to a square lithium battery discharge device. Background Technology

[0002] Square lithium batteries possess advantages such as high energy density, long cycle life, and good safety, and are widely used in new energy vehicles, energy storage systems, and consumer electronics. In the mass production of square lithium batteries, after packaging and testing, the batteries need to be removed from the production line by an unloading device and transferred to pallets for stacking before subsequent warehousing or packaging. The efficiency and reliability of the unloading process directly affect the overall production line capacity and product yield.

[0003] Currently, the unloading process for square lithium batteries typically involves the following steps: a robotic arm moves the processed square lithium batteries from the previous workstation, a transfer mechanism transports the batteries to the tray loading station, and finally, a stacking mechanism places the batteries one by one into the recesses of the carrier tray. To achieve this process, existing unloading devices are generally equipped with components such as an adsorption mechanism, a flipping mechanism, a translation mechanism, and a carrier mechanism.

[0004] However, existing square lithium battery discharge devices still have the following shortcomings in practical applications: The continuity of material output is poor, and the transfer efficiency needs to be improved. Most existing material output devices use a single-layer transfer structure. After receiving material from the front end, the transfer mechanism must wait for the rear end to complete loading before it can receive material again. Receiving and feeding cannot be done simultaneously, resulting in waiting time and hindering continuous operation. Furthermore, some equipment still requires manual assistance for loading and unloading, indicating a low level of automation and making it difficult to meet the high efficiency requirements of large-scale production.

[0005] The reliability of adsorption-transfer is insufficient, posing safety hazards. Suction cups are commonly used adsorption components in square lithium battery discharging devices, using vacuum to create negative pressure and fix the batteries in place. However, during long-term use, gas leaks inevitably occur at the connections between the suction cup and the air pipe / pump. Once a leak occurs, the negative pressure inside the suction cup cannot be maintained, the adsorption force decreases, and the square lithium batteries are prone to falling during transfer. Since the casings of square lithium batteries are mostly made of metal, if the positive and negative terminals of the battery simultaneously come into contact with the metal parts of the equipment upon falling, it can cause a short circuit, potentially leading to serious safety accidents such as high-temperature spontaneous combustion. Furthermore, the falling battery itself can damage the product, increasing production costs. Summary of the Invention

An L-shaped frame is provided on both the first and second limiting seats, and a suction cup is disposed on the side end of the L-shaped frame.

[0012] Preferably, the upper end of the auxiliary frame is provided with a first cylinder, and there are three first cylinders. The output ends of the first cylinders on both sides are connected to the second limiting rail, and the output end of the first cylinder in the middle is connected to the first limiting seat.

[0013] Preferably, a second cylinder is provided at the side end of the second limiting rail, the output end of the second cylinder is connected to the L-shaped frame, a transfer motor is also provided on the gantry frame, a loop transmission belt is provided on the gantry frame, the loop transmission belt is connected to the auxiliary frame, and the output end of the transfer motor drives the loop transmission belt to rotate.

[0014] Preferably, the supporting component includes a supporting rail, which is disposed on the upper end of the support cabinet. A supporting slide is slidably disposed on the supporting rail. A lifting hydraulic cylinder is disposed at each of the four corners of the upper end of the supporting slide. A supporting plate is disposed at the output end of the lifting hydraulic cylinder. A supporting plate is placed on the upper end of the supporting plate.

[0015] Preferably, the upper end of the support cabinet is also provided with a load-bearing motor, and a loop belt is provided on the load-bearing track. The loop belt is connected to the load-bearing slide, and the output end of the load-bearing motor drives the loop belt to rotate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The double-layer transfer structure of the first transfer component, with the lower layer lifting cylinder having a greater stroke than the upper layer, enables the double-layer alternating operation, allowing the equipment to continuously receive material from the front-end robotic arm and supply material to the rear end, significantly improving the overall material output efficiency.

[0017] The mounting bracket, rotating shaft, mounting plate, flipping motor, drive gear, driven gear, and transmission belt of the flipping component work together to drive the suction cup adsorption end to flip, facilitating accurate docking with the front robotic arm; after adsorption, it flips downwards and is clamped by the clamping plate of the first transfer component to achieve smooth transfer.

[0020] The suction cup creates negative pressure for adsorption by suction and releases it by blowing air. This, combined with the coordinated actions of the first and second transfer components and the flipping component, enables reliable gripping. The lower end of the suction cup is made of rubber, with an internally added conical rubber ring with a slit and interference fit. When there is a leak in the upper part of the suction cup, a sealed cavity is formed between the conical rubber ring, the lower end of the suction cup, and the square lithium battery, ensuring a firm grip. The battery's own weight and inertia further tighten the seal, effectively preventing accidental drops during transport.

[0021] When the air is blown out, the conical rubber ring deflects downward due to the airflow and generates slight vibrations, which can fine-tune the tilted posture of the square lithium battery in the recess of the carrier plate, so that it is correctly positioned; at the same time, the blowing airflow can also clean the battery surface, which is conducive to more stable subsequent adsorption.

[0024] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0025] Example 1 like Figures 1 to 6 As shown, the present invention discloses a square lithium battery unloading device, including a support cabinet 1. The upper end of the support cabinet 1 is provided with a first transfer component 2, a second transfer component 3 and a bearing component 4. The upper end of the first transfer component 2 is provided with a flipping component 5. The square lithium battery held by the front robotic arm will move to the upper end of the flipping component 5. With the assistance of the flipping component 5, the square lithium battery is adsorbed. Then the flipping component 5 places the square lithium battery on the first transfer component 2. Then the second transfer component 3 transfers the square lithium battery on the first transfer component 2 into the bearing component 4, thus completing the tray unloading of the square lithium battery.

[0026] The first transfer component 2 adopts a double-layer transfer structure. Through the double-layer transfer structure, the first transfer component 2 can continuously receive materials from the front robotic arm and supply materials to the rear second transfer component 3, so that the equipment can maintain continuous operation.

[0027] Both the first transfer component 2 and the second transfer component 3 are equipped with suction cups 6. With the assistance of the suction cups 6, the suction cups 6 are attached to the surface of the square lithium battery. By evacuating the suction cups 6, a negative pressure is formed inside the suction cups 6, which enables the suction cups 6 to adsorb and fix the square lithium battery.

[0028] The flipping component 5 includes a mounting frame 501, which is located on the upper end of the support cabinet 1. A rotating shaft 502 is rotatably mounted on the mounting frame 501, and a mounting plate 503 is located on the side end of the rotating shaft 502. Multiple suction cups 6 are mounted on the mounting plate 503. A flipping motor 504 is mounted on the mounting frame 501, and a drive gear 505 is located at the output end of the flipping motor 504. A driven gear 506 is located on the rotating shaft 502, and a transmission belt is provided between the drive gear 505 and the driven gear 506. When the flipping motor 504 is started, the output end of the flipping motor 504 drives the drive gear 505 to rotate. The rotation of the drive gear 505 drives the driven gear 506 to rotate through the transmission belt. The rotation of the driven gear 506 causes the mounting plate 503 to flip, thereby causing the suction end of the suction cup 6 to flip, making it easier for the suction cup 6 to cooperate and dock with the front-end robotic arm.

[0029] The first transfer component 2 includes a mounting base 201, which is disposed on the upper end of the support cabinet 1. A vertical plate 202 is disposed on the upper end of the mounting base 201. A slide rail 203 is disposed on the vertical plate 202. A slide block 204 is slidably disposed on the upper end of the slide rail 203. A lifting cylinder 205 is disposed on the slide block 204. A base plate 206 is disposed on the output end of the lifting cylinder 205. An opening is provided in the middle of the base plate 206. A clamping cylinder 207 is disposed in the opening. A clamping plate 208 is disposed on the output end of the clamping cylinder 207. The clamping plate 208 is located on the upper end of the base plate 206. A moving cylinder 209 is also disposed on the side end of the vertical plate 202. The output end of the moving cylinder 209 is connected to the slide block 204. After the suction cup 6 of the flipping component 5 adsorbs the square lithium battery, the flipping component 5 flips the suction cup 6. The device moves downwards, and then the lifting cylinder 205 is activated. The output end of the lifting cylinder 205 drives the substrate 206 to rise, bringing the square lithium battery between the two clamping plates 208. Then, the clamping cylinder 207 is activated, and the output end of the clamping cylinder 207 drives the clamping plates 208 to move. The two clamping plates 208 move towards each other, completing the clamping of the square lithium battery. After that, the suction cup 6 of the flipping component 5 starts blowing air to release the square lithium battery. At this time, the square lithium battery is clamped and fixed between the two clamping plates 208. After that, the substrate 206 returns to its initial height, and the moving cylinder 209 is activated. With the assistance of the moving cylinder 209, the slide 204 moves along the slide rail 203, bringing the square lithium battery below the second transfer component 3, which facilitates the operation of the second transfer component 3.

[0030] The slide rail 203, slide block 204, lifting cylinder 205, base plate 206, clamping cylinder 207, clamping plate 208 and moving cylinder 209 constitute the transfer unit of the first transfer component 2. There are two transfer units, which are distributed vertically. The stroke of the lifting cylinder 205 of the lower transfer unit is greater than that of the lifting cylinder 205 of the upper transfer unit. By using the alternating operation of the two-layer transfer units, the continuous receiving and feeding of materials by the first transfer component 2 is completed, ensuring the operating efficiency of the entire equipment.

[0031] The second transfer component 3 includes a gantry frame 301, which is mounted on the upper end of the support cabinet 1. A track 302 is provided on the upper side of the gantry frame 301, and an auxiliary frame 303 is slidably mounted on the track 302. A first limiting rail 304 is provided on the side of the auxiliary frame 303. Three first limiting rails 304 are provided; a second limiting rail 305 is slidably mounted on each of the two side first limiting rails 304; a first limiting seat 306 is slidably mounted on the middle first limiting rail 304; and a second limiting seat 307 is slidably mounted on the second limiting rail 305. The first limiting seat 306 and the second limiting seat... Each of the components 307 is equipped with an L-shaped frame 310, with the suction cup 6 located on the side of the L-shaped frame 310. The auxiliary frame 303 can move along the track 302 to make long-distance adjustments to the suction cup 6 on the second transfer component 3. Then, the second limiting rail 305 can move on the first limiting rail 304 to achieve longitudinal adjustment of the suction cup 6. The second limiting seat 307 can move laterally on the second limiting rail 305 to achieve fine adjustment of the lateral position of the suction cup 6. The first limiting seat 306 can move along the middle first limiting rail 304 to achieve longitudinal adjustment of the middle suction cup 6.

[0032] The upper end of the auxiliary frame 303 is equipped with a first cylinder 308. There are three first cylinders 308. The output ends of the first cylinders 308 on both sides are connected to the second limit rail 305, and the output end of the first cylinder 308 in the middle is connected to the first limit seat 306. When the first cylinders 308 are started, the second limit rail 305 and the first limit seat 306 are raised and lowered, thereby completing the longitudinal adjustment of the suction cup 6.

[0033] A second cylinder 309 is provided on the side end of the second limiting rail 305. The output end of the second cylinder 309 is connected to the L-shaped frame 310. A transfer motor 311 is also provided on the gantry frame 301. A loop transmission belt is provided on the gantry frame 301. The loop transmission belt is connected to the auxiliary frame 303. The output end of the transfer motor 311 drives the loop transmission belt to rotate, starting the second cylinder 309. The output end of the second cylinder 309 drives the L-shaped frame 310 to move, thereby completing the lateral fine adjustment of the suction cup 6. At the same time, the transfer motor 311 drives the auxiliary frame 303 to move along the track 302 through the auxiliary drive of the loop transmission belt, realizing the large distance adjustment of the suction cup 6.

[0034] The supporting component 4 includes a supporting rail 401, which is located on the upper end of the support cabinet 1. A supporting slide 402 is slidably mounted on the supporting rail 401. A lifting hydraulic cylinder 403 is installed at each of the four corners of the upper end of the supporting slide 402. A supporting plate 404 is installed at the output end of the lifting hydraulic cylinder 403. A supporting plate 405 is placed on the upper end of the supporting plate 404. By sliding the supporting slide 402, the supporting plate 404 moves along the direction of the supporting rail 401. The lifting hydraulic cylinder 403 is activated, thereby changing the height of the supporting plate 404, so that the supporting plate 405 can better match the suction cup 6, making it easier to insert the square lithium battery on the suction cup 6.

[0035] The upper end of the support cabinet 1 is also equipped with a load-bearing motor 406, and a loop belt is installed on the load-bearing track 401. The loop belt is connected to the load-bearing slide 402. The output end of the load-bearing motor 406 drives the loop belt to rotate. When the load-bearing motor 406 is started, the output end of the load-bearing motor 406 drives the load-bearing slide 402 to move along the load-bearing track 401 with the assistance of the loop belt.

[0036] In use, the front-end robotic arm transports the square lithium battery to the top of the flipping component 5, starts the flipping motor 504, and drives the drive gear 505 to rotate through the output end of the flipping motor 504. The rotation of the drive gear 505 drives the driven gear 506 to rotate through the transmission belt. The rotation of the driven gear 506 causes the mounting plate 503 to flip, which in turn causes the suction end of the suction cup 6 to flip, so that the suction end of the suction cup 6 of the flipping component 5 is facing upward. Then, with the assistance of the front-end robotic arm, the square lithium battery is pressed onto the suction cup 6. Simultaneously, the air pump connected to the suction cup 6 operates, so that the suction cup 6 generates suction force to achieve the adsorption and fixation of the square lithium battery. After the adsorption and fixation are completed, the front-end robotic arm releases the clamp on the square lithium battery to transfer the next batch of lithium batteries. Then, the flipping component 5 operates, so that the suction cup 6 of the flipping component 5 adsorbs the square lithium battery and flips downward.

[0037] The lifting cylinder 205 is activated, and its output end drives the substrate 206 to rise, bringing the square lithium battery between the two clamping plates 208. Then, the clamping cylinder 207 is activated, and its output end drives the clamping plates 208 to move. The two clamping plates 208 move towards each other, completing the clamping of the square lithium battery. After that, the suction cup 6 of the flipping component 5 starts blowing air to release the square lithium battery. At this time, the square lithium battery is clamped and fixed between the two clamping plates 208. After that, the substrate 206 returns to its initial height, and the moving cylinder 209 is activated. With the assistance of the moving cylinder 209, the slide 204 moves along the slide rail 203, bringing the square lithium battery below the second transfer component 3, which facilitates the operation of the second transfer component 3. At the same time, through the double-layer transfer structure, the first transfer component 2 can continuously receive materials from the front robotic arm and supply materials to the rear second transfer component 3, so that the equipment can maintain continuous operation.

[0038] The transfer motor 311 drives the auxiliary frame 303 via the loop transmission belt to move along the track 302, causing the suction cup 6 of the second transfer component 3 to move above the first transfer component 2. The first cylinder 308 is activated, causing the second limit rail 305 and the first limit seat 306 to rise and fall, thereby completing the longitudinal adjustment of the suction cup 6. The second cylinder 309 is activated, and the output end of the second cylinder 309 drives the L-shaped frame 310 to move, thereby completing the lateral fine adjustment of the suction cup 6, so that the suction cup 6 of the second transfer component 3 is aligned with and pressed onto the square lithium battery on the first transfer component 2. Then, the air pump connected to the suction cup 6 of the second transfer component 3 operates, causing the suction cup 6 to adsorb and fix the square lithium battery. Simultaneously, the clamping cylinder 207 of the first transfer component 2 operates, causing the clamping of the square lithium battery by the first transfer component 2 to be released, making it easier for the second transfer component 3 to transfer the square lithium battery.

[0039] The transfer motor 311 drives the auxiliary frame 303 along the track 302 via the auxiliary drive belt, so that the suction cup 6 of the second transfer component 3 adsorbs the square lithium battery and moves it above the support component 4.

[0040] Start the carrier motor 406. The output end of the carrier motor 406 drives the carrier slide 402 to move along the carrier track 401 through the auxiliary drive of the loop belt. Start the lifting hydraulic cylinder 403, so that the height of the carrier plate 404 changes, so that the carrier plate 405 can better match the suction cup 6. Through the cooperation of the carrier component 4 and the second transfer component 3, the square lithium batteries are stacked one by one in the placement pit of the carrier plate 405.

[0041] Example 2 Based on the above embodiment 1, a square lithium battery discharging device requires that the connection between the suction cup 6 and the air pipe and air pump be kept sealed during the discharging and transfer of square lithium batteries. However, during long-term use, gas leaks are inevitable. When a gas leak occurs, the square lithium batteries are prone to detachment during the transfer process when the suction cup 6 adsorbs them. Since the entire device is often made of metal, if a square lithium battery falls and becomes electrically connected, such as if the positive and negative terminals of the square lithium battery simultaneously contact the metal plate, it will cause a short circuit in the square lithium battery, which can easily lead to high-temperature spontaneous combustion. At the same time, the falling of the square lithium battery will also cause damage to itself. Therefore, the following improvement scheme is proposed to reduce the accidental falling of square lithium batteries when gas leaks exist: like Figures 1 to 8 As shown, the lower end of the suction cup 6 is made of rubber. A conical rubber ring 7 is also provided inside the suction cup 6. The conical rubber ring 7 has slits, and the slits are press-fitted. When the suction cup 6 adsorbs and fixes the square lithium battery, the air pump generates suction through the air tube. If the seal is good, no air will enter the suction cup 6 after the air pump stops operating. Therefore, the suction cup 6 can firmly adsorb and fix the square lithium battery. If there is a leak, due to the presence of the conical rubber ring 7, the lower end of the suction cup 6 and the square lithium battery will remain sealed. A sealed cavity is formed between the pools, ensuring that the suction cup 6 can firmly adsorb the square lithium battery. Due to the elasticity of the conical rubber ring 7, the gravity of the square lithium battery itself, and the inertia of the square lithium battery when it moves, the seal of the conical rubber ring 7 becomes even tighter during transportation, ensuring that the square lithium battery will not fall off due to air leakage at the top of the suction cup 6. At the same time, in the event of an unexpected power outage, it can also prevent the square lithium battery on the suction cup 6 from falling off and being damaged due to the inertial impact of the power outage.

[0042] When the square lithium battery is placed into the recess of the carrier plate 405, the air pump will run in reverse, causing the suction cup 6 to produce a blowing effect. At this time, the conical rubber ring 7 will deflect downward due to the gas and vibrate slightly due to the airflow. When the conical rubber ring 7 deflects downward and vibrates slightly to contact the square lithium battery, it can adjust the posture of the square lithium battery in the recess, so that the square lithium battery that is placed crooked can be correctly matched with the recess.

[0043] Meanwhile, when the suction cup 6 blows air onto the square lithium battery, the blowing effect of the suction cup 6 can clean the surface of the square lithium battery, ensuring that the suction cup 6 can adsorb it more stably in the future.

[0044] The main function achieved by this invention is: through the double-layer transfer structure of the first transfer component 2, and with the lower layer lifting cylinder 205 having a greater stroke than the upper layer, the double-layer alternating operation is realized, enabling the equipment to continuously receive materials from the front-end robotic arm and supply materials to the rear end, thereby greatly improving the overall material output efficiency.

[0045] The mounting bracket 501, rotating shaft 502, mounting plate 503, flipping motor 504, drive gear 505, driven gear 506 and transmission belt of the flipping component 5 cooperate to drive the suction cup 6 to flip, so as to facilitate accurate docking with the front robotic arm; after suction, it flips downward and is clamped with the clamping plate 208 of the first transfer component 2 to achieve smooth transfer.

[0046] The second transfer component 3 is equipped with a gantry frame 301, a track 302, an auxiliary frame 303, a first limiting rail 304, a second limiting rail 305, a first limiting seat 306, a second limiting seat 307, and an L-shaped frame 310. It achieves longitudinal lifting through a first cylinder 308, achieves lateral fine adjustment through a second cylinder 309, and is driven by a transfer motor 311 and a loop transmission belt to move a long distance, so that the suction cup 6 can be accurately positioned to complete the stable picking and placement of the square lithium battery from the first transfer component 2 to the carrier component 4.

[0047] The supporting component 4 has a supporting track 401, a supporting slide 402, a lifting hydraulic cylinder 403, a supporting plate 404, a supporting disk 405, a supporting motor 406, and a loop belt. These components can drive the supporting slide 402 to move and adjust the height of the supporting plate 404, so that the supporting disk 405 can be precisely matched with the suction cup 6 of the second transfer component 3. This facilitates the stacking of square lithium batteries one by one in the pit, improving the quality of the tray loading.

[0048] The suction cup 6 uses vacuum to create negative pressure for adsorption and air to release it. Combined with the coordinated actions of the first transfer component 2, the second transfer component 3, and the flipping component 5, it achieves reliable gripping. The lower end of the suction cup 6 is made of rubber, with an internally added conical rubber ring 7 that has a slit and an interference fit. When there is a leak in the upper part of the suction cup 6, the conical rubber ring 7, the lower end of the suction cup 6, and the square lithium battery form a sealed cavity, ensuring a firm adsorption. The battery's own weight and inertia further tighten the seal, effectively preventing accidental drops during transport.

[0049] When the air is blown out, the conical rubber ring 7 deflects downward due to the airflow and generates slight vibrations, which can finely adjust the tilted posture of the square lithium battery in the recess of the support plate 405, so that it is correctly positioned; at the same time, the blowing airflow can also clean the battery surface, which is conducive to more stable subsequent adsorption.

[0050] The square lithium battery discharging device of the present invention can be installed, connected or set in a common mechanical manner, and can be implemented as long as it can achieve its beneficial effect.
