Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery processing, and in particular to a pressing device for lithium battery processing and production. Background Art

[0002] In the battery manufacturing industry, the performance of battery pressing devices plays a key role in product quality. Currently, this device has significant technical shortcomings in the lubrication and battery shell fixing stages.

[0003] Traditional lubrication methods rely primarily on manual operation or fixed pipeline oil supply. Manual operation varies from worker to worker, making it difficult to standardize refueling intervals and oil quantities. Fixed pipeline oil supply, while relatively stable, continuously delivers oil at a set flow rate regardless of the component's actual operating conditions. Neither method allows for adjustment of oil supply based on the real-time operating status of transmission components.

[0004] In the battery pressing process, the problem of fixing the battery shell is also prominent. When the battery shell is in the pressing station, there is a lack of effective fixing measures. In the process of pressing the battery cell, the battery cell is subjected to strong extrusion force. Since the battery shell is not stable, relative sliding is very likely to occur between the battery cell and the battery shell. For example, in the pressing process of square lithium batteries, a slight misalignment between the battery cell and the shell may cause abnormal connection of the internal electrodes, and in severe cases, it may cause safety hazards. This inaccurate pressing problem caused by the unfixed battery shell has greatly affected the yield and production efficiency of battery production, and has become a bottleneck restricting the further development of the battery manufacturing industry.

DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] See also Figure 1 As shown, the embodiments provided by the present invention are:

[0042] Example 1

[0043] A pressing device for lithium battery processing and production comprises: a tabletop 1, on which are mounted limiting modules 2 and a power assembly 5 arranged in a circular array, with the power assembly 5 located at the center of the tabletop 1. The limiting modules 2 adopt a circular array layout design, which enables the continuous flow of battery modules to be pressed from the feeding station to the pressing station, while simultaneously transferring the pressed battery modules to the unloading station, significantly improving production efficiency and reducing waiting time between stations. The limiting modules 2 also generate an adsorption force on the battery through the effect of airflow adsorption. When the battery changes stations to the unloading station, it is not adsorbed, facilitating battery unloading. The power assembly 5 is set in the center position.

[0044] Transmission components 6 are distributed in a circular array on the table top 1, and the transmission components 6 are located between the limit module 2 and the power component 5. The power component 5 drives the transmission components 6 distributed in the circular array to move, and the transmission components 6 drive the pressing module 3 to press the battery modules to be pressed distributed in the circular array. The transmission components 6 distributed in the circular array can realize multi-station synchronous processing, significantly improving the utilization rate of the equipment; the pressing module 3 installed at its end ensures that the force is evenly distributed during the pressing process of the battery module, thereby improving product consistency. The circular motion structure design shortens the movement path between adjacent stations and reduces the idle travel time; at the same time, through multi-station cycle operation, the placement and removal time of the battery is buffered, so that workers have relatively ample time to operate at each station, reducing the intensity of manual operation. When the pressing module 3 is reset, it drives the limit module 2 to realize the flow of the battery modules to be pressed from the feeding station to the pressing station, and at the same time, the battery modules that have been pressed are synchronously transferred to the unloading station.

[0045] The transmission assembly 6 is provided with a lubrication assembly 4, which lubricates the pressing die 3. It provides lubrication protection during the movement of the pressing die 3, effectively reducing mechanical wear, extending the service life of the equipment, and reducing maintenance costs.

[0046] Example 2

[0047] In order to improve the overall transmission efficiency and stability of the equipment, for example, Figures 8 to 10 As shown, the present invention also includes:

[0048] The power component 5 includes a motor 510 arranged at the bottom end of the table board 1, and a retaining ring 505 is installed at the upper end of the table board 1. The retaining ring 505 has the dual functions of dust protection and motion limit, which prolongs the life of the internal conduit 506. The conduit 506 is installed in the retaining ring 505. The output end of the motor 510 passes through the table board 1, and the output end of the motor 510 is installed with a rotor 507. The rotor 507 is installed with a pressure wheel 502. The pressure wheel 502 is driven by the rotation of the rotor 507 to squeeze the conduit 506. This method of driving the pressure wheel to squeeze the conduit by the rotor can achieve stable and efficient gas delivery control. The extrusion process is smooth and can accurately control the gas flow and pressure. An air outlet connector 503 and an air extraction connector 504 are provided at both ends of the conduit 506, and the air extraction connector 504 of the conduit 506 is connected to the limit module 2. The negative pressure adsorption principle is used to enhance the stability of the battery module to be pressed during the circulation process, avoid displacement deviation caused by inertia or vibration, and improve positioning accuracy.

[0049] The power assembly 5 also includes a rotating head 509, which has a protrusion 508 on the outside. The rotating head 509 pushes the connecting shaft 605 through the protrusion 508. A planetary reducer 501 is provided on the table 1, and the output end of the motor 510 is connected to the input shaft of the planetary reducer 501 through the rotor 507. The output shaft of the planetary reducer 501 is connected to the rotating head 509. The planetary reducer 501 can effectively reduce the speed of the motor, increase the torque, and provide suitable power output for the rotating head 509, thereby ensuring the stable operation of the entire power assembly 5. The connection design of the exhaust joint 504 and the limit module 2 further optimizes the collaborative efficiency between workstations, shortens the fixing time of the battery module through negative pressure adsorption, and cooperates with the ring array flow layout to shorten the single batch production cycle while reducing the difficulty of manual positioning for workers.

[0050] Example 3

[0051] In order to achieve efficient, accurate and stable pressing operation in the production process of lithium battery, while reducing equipment maintenance costs and manual intervention, and improving overall production efficiency, for example, Figure 2 、 Figure 4 and Figure 6 As shown, the present invention also includes:

[0052] The transmission component 6 includes a connecting shaft 605, one end of the connecting shaft 605 is installed with a bearing 601 through a connecting head 604, ensuring that the protrusion 508 of the rotating head 509 pushes the connecting shaft 605 by squeezing the bearing 601, which can effectively reduce mechanical friction loss, make the transmission process more stable and smooth, and avoid jamming. The pressing module 3 is installed at the end of the connecting shaft 605 away from the bearing 601. The end of the transmission component 6 where the pressing module 3 is installed is provided with a pressure chamber 607. When the fixed plate 307 presses the battery module, the elastic member 303 is used to buffer the fixed plate 307, effectively protecting the battery cell from excessive extrusion and deformation. The elastic member 303 is preferably a spring. When the fixed plate 307 buffers, it will push the sealing plate 304 to produce displacement in the pressure chamber 607, resulting in the pressure chamber 6 The increased air pressure within chamber 07 creates stored air pressure energy. When transmission assembly 6 resets, the increased air pressure within pressure chamber 607 drives fixed plate 307 to reset. Simultaneously, elastic member 303 assists in resetting fixed plate 307. The synergistic effect of air pressure and elastic member quickly resets the fixed plate, shortening reset time and ensuring precise and controllable reset action. Transmission assembly 6 is equipped with a push plate 606, which is mounted on a connecting frame 602. A strong magnet 603 is mounted on connecting frame 602. The piston head 409 within the oil feeder 401 is connected to an electromagnet 407 via a pull rod 408. The strong magnet 603 on connecting frame 602 forms a magnetic coupling drive with the piston head 409 of the oil feeder 401. The linkage design between electromagnet 407 and pull rod 408 enables intelligent quantitative lubrication control. Users can set oil supply parameters based on operating time or the number of times transmission assembly 6 moves, achieving automatic relubrication and significantly reducing the frequency of manual maintenance. The system can also monitor lubrication status in real time to ensure that the equipment is always in good operating condition, effectively reducing mechanical wear and extending the service life of key components.

[0053] Example 4

[0054] In order to achieve high-precision and high-quality pressing of lithium battery modules, to maximize the performance and consistency of the battery modules, while optimizing the stability and reliability of equipment operation and extending the service life of the equipment, for example, Figures 1 to 4 As shown, the present invention also includes:

[0055] The pressing module 3 includes a fixed plate 307, and a guide shaft 306 is provided on the fixed plate 307 to ensure that the fixed plate 307 always maintains linear motion during the pressing process, effectively avoiding the problem of uneven pressing of the battery module due to tilting, and improving product consistency. The end of the guide shaft 306 away from the fixed plate 307 is connected to the sealing plate 304 through the connecting rod 305. The sealing plate 304 forms a precise fit with the inner wall of the pressure chamber 607, optimizing the gas pressure energy storage efficiency while preventing gas leakage, ensuring that the reset driving force is stable and reliable. A pressing head 301 is installed on the fixed plate 307, and the battery cell is pressed into the shell through the pressing head 301. The battery cell and the shell are assembled by interference fit. A flexible toothed belt 302 is installed on one side of the pressing head 301. The flexible toothed belt is made of high-strength composite material, has good tensile and wear resistance, and extends its service life.

[0056] Sealing plate 304 is located within pressure chamber 607. Transmission assembly 6 is fitted with a sealing ring 608 on connecting rod 305. Made of high-temperature-resistant fluororubber, sealing ring 608 maintains an excellent seal during long-term, high-frequency movement, preventing lubricant or gas leakage from contaminating the battery module. Guide shaft 306, located between connecting shaft 605 and fixing plate 307, is fitted with an elastic member 303. The elastic member 303 adaptively adjusts the preload pressure based on the thickness of the battery module, ensuring a tight fit while preventing excessive compression of the battery cells. During the pressing process, the elastic buffer design effectively absorbs vibration and impact energy from the equipment, reducing the risk of damage to the battery's internal structure. It also provides auxiliary power for subsequent air pressure reset, improving overall reset efficiency.

[0057] Example 5

[0058] In order to meet the requirements of accurate positioning, efficient flow and stable pressing of battery modules in the process of lithium battery processing and production, the production efficiency can be greatly improved and the defective rate can be reduced. For example, Figures 1 to 4 As shown, the present invention also includes:

[0059] The limiting module 2 includes an outer frame 210 disposed on the table top 1. A gear ring 205 is installed at the bottom end of the outer frame 210. A ratchet 206 is elastically installed in the gear ring 205 via a torsion spring. The one-way locking design effectively prevents reverse movement, improves the positioning accuracy of the battery module when it flows between workstations, and avoids displacement deviation caused by vibration or inertia.

[0060] A rotating block 204 is installed in the outer frame 210, and the rotating block 204 is installed outside the vacuum roller 201. An exhaust port 208 is opened on the vacuum roller 201. The exhaust port 208 is a strip window, and the exhaust port 208 covers the loading station and the pressing station, providing stable adsorption force during the circulation of the battery module, ensuring that the module maintains a fixed position during high-speed movement, and a ratchet 207 is installed at the bottom end of the rotating block 204. The ratchet 207 at the bottom end of the rotating block 204 is engaged with the ratchet 206 of the gear ring 205 for transmission. This one-way drive structure design has multiple advantages: first, through the tooth shape matching of the ratchet and the ratchet, it is ensured that the rotating block 204 can only rotate in the preset direction, effectively preventing reverse movement, and ensuring that the battery module is in the circulation process. Always facing the target workstation; secondly, the meshing transmission has a self-locking function. When the pressing head 301 releases the driving force, the ratchet 206 automatically snaps into the tooth groove of the gear ring 205 under the action of the torsion spring, so that the rotating block 204 maintains a fixed position to avoid workstation displacement caused by external interference. Three limit grooves 203 are provided on the outside of the rotating block 204, and the limit groove 203 facing the pressing head 301 is the pressing workstation. The limit grooves 203 on both sides of the pressing workstation are respectively the loading workstation and the unloading workstation. A negative pressure hole 202 is provided in the limit groove 203, and the position of the negative pressure hole 202 corresponds to the position of the exhaust port 208. The battery module fixing effect is enhanced by vacuum adsorption, and the battery module can still be kept stable, especially under complex working conditions.

[0061] A guide groove 209 is provided at the bottom end of the outer frame 210. The guide groove 209 is used to guide the flexible toothed belt 302, reduce lateral deviation during operation, reduce transmission noise, and improve overall transmission efficiency. The flexible toothed belt 302 drives the ring gear 205 to rotate, and the ring gear 205 drives the ratchet 207 to drive the rotating block 204 to rotate in one direction, thereby realizing the continuous flow of the battery modules to be pressed from the feeding station to the pressing station, and at the same time, the battery modules that have been pressed are synchronously transferred to the unloading station, which significantly improves production efficiency and reduces waiting time between stations.

[0062] Example 6

[0063] In order to ensure that the key moving parts of the pressing device for lithium battery processing and production can maintain good performance in long-term high-intensity operation, effectively reduce equipment wear, improve equipment operation stability and service life, and realize intelligent and precise lubrication management, for example, Figures 1 to 4 As shown, the present invention also includes:

[0064] The lubrication assembly 4 includes a guide seat 405, an oil feeder 401 is provided above the guide seat 405, an oil box 402 is provided on the oil feeder 401, the oil box 402 provides a reliable storage space for the lubricating oil, and its large capacity can reduce the trouble of frequently adding lubricating oil and improve the convenience of using the equipment. A rubber plug 410 is installed on the oil box 402, and the rubber plug 410 has good sealing performance, which can effectively prevent the leakage of lubricating oil and external dust and debris from entering the oil box, thereby ensuring the cleanliness of the lubricating oil and prolonging the lubrication. To extend the service life of lubricating oil and equipment, the oil feeder 401 is connected to the oil box 402 through the oil extraction pipe 404, and the oil feeder 401 is connected to the contact position of the guide shaft 306 and the connecting shaft 605 through the oil delivery pipe 403, and a one-way valve is provided at the connection between the oil feeder 401, the oil delivery pipe 403 and the oil extraction pipe 404. The one-way valve can accurately control the flow direction of the lubricating oil to prevent the lubricating oil from flowing back, ensuring that the lubricating oil can be efficiently and stably delivered to the parts that need lubrication, reducing equipment wear and improving equipment operation efficiency.

[0065] A pull rod 408 is installed inside the oil feeder 401, with a piston head 409 mounted on its end. An electromagnet 407 is mounted on the end of the pull rod 408 facing away from the piston head 409. The strong magnet 603 and the electromagnet 407 drive the piston head 409 to move within the oil feeder 401. This electromagnetically driven piston head movement makes lubricating oil delivery more precise and controllable. Users can flexibly adjust the electromagnet's operating parameters based on the actual operating conditions of the equipment, thereby precisely controlling the amount and frequency of lubricating oil delivery, avoiding waste and insufficient lubricating oil and providing optimal lubrication protection for the equipment.

[0066] A return spring 411 is installed within the guide seat 405. The connecting shaft 605 is reset by the push plate 606 and the return spring 411. The return spring 411 has excellent elasticity and recovery properties. It quickly and accurately returns the connecting shaft 605 to its initial position after completing a single movement, ensuring stable and efficient operation of the device's cycle. Furthermore, the cushioning effect of the return spring 411 reduces the impact force generated by the connecting shaft 605 during the reset process, reducing noise and wear on the device, and extending its service life.

[0067] Working principle:

[0068] The motor 510 starts, and the output shaft of the motor 510 drives the rotor 507 to rotate. The pressure wheel 502 on the rotor 507 squeezes the conduit 506, causing the conduit 506 to generate negative pressure. The strip-shaped exhaust port 208 on the vacuum roller 201 extracts air through the conduit 506 to generate negative pressure. The limiting groove 203 of the rotating block 204 is provided with a negative pressure hole 202. Then, the worker places the battery module to be pressed into the loading station of the rotating block 204 and fixes the battery module by vacuum adsorption. At the same time, the output shaft of the motor 510 drives the rotor 507 and the planetary reducer 501. The output shaft of the planetary reducer 501 is connected to the rotating head 509. The protrusion 508 on the outside of the rotating head 509 pushes the connecting shaft 605. The connecting shaft 605 drives the fixed plate 307 to move, and when the fixed plate 307 presses the battery module. While the fixing plate 307 presses the battery module, the fixing plate 307 pushes the sealing plate 304 through the guide shaft 306 to generate displacement in the pressure chamber 607, thereby increasing the air pressure in the pressure chamber 607 to form air pressure energy storage.

[0069] After the pressing head 301 completes the pressing operation, it enters the reset phase. The increased air pressure within the pressure chamber 607 drives the fixed plate 307 to reset, and the elastic member 303 assists in the reset of the fixed plate 307. The connecting shaft 605 is reset by the push plate 606 and the reset spring 411 within the guide seat 405.

[0070] During the repositioning of the connecting shaft 605, the flexible toothed belt 302 on one side of the pressing head 301 moves synchronously within the guide slot 209. The flexible toothed belt 302 drives the ring gear 205 at the bottom of the outer frame 210 to rotate. The ring gear 205 engages with the ratchet 207 at the bottom of the rotating block 204, driving the rotating block 204 in unidirectional rotation. The rotation of the rotating block 204 transfers the battery modules to be pressed from the loading station to the pressing station, while simultaneously transferring the completed pressed battery modules to the unloading station.

[0071] During the movement of guide shaft 306, piston head 409 in oil feeder 401 above guide seat 405 is connected to electromagnet 407 via pull rod 408. Strong magnet 603 on connecting frame 602 forms a magnetic coupling with piston head 409, driving the movement. Oil feeder 401 draws lubricating oil from oil box 402 via oil extraction pipe 404 and delivers it via oil delivery pipe 403 to the contact point between guide shaft 306 and connecting shaft 605.

[0072] After the rotating block 204 transfers the pressed battery module to the unloading station, the worker removes the battery module. The one-way locking structure of the limit module 2 prevents the rotating block 204 from moving in the opposite direction, ensuring that the battery module always faces the correct position during the flow process and avoiding position deviation caused by external interference.

[0073] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
