Description

Technical Field

[0002] Milling equipment for lithium battery module terminals is primarily used to perform precision machining operations such as milling and drilling on these terminals. High-precision machining ensures the terminal's flatness, dimensional accuracy, and shape meet design requirements, thereby improving the connection between the terminal and the battery cell and enhancing the overall performance and safety of the lithium battery module. Traditional milling equipment for lithium battery module terminals uses a fine-adjustment nut method for milling head installation, which presents numerous drawbacks. The installation process requires manual tightening of the nut using tools such as screwdrivers and wrenches until the milling clamp is secure. This cumbersome and time-consuming process results in low overall installation efficiency. Furthermore, installation quality is highly dependent on the operator's skill and experience, and variations in operator performance can lead to inconsistent milling head installation quality. Furthermore, the operator directly touches components such as the milling head and nut during operation, posing a risk of mechanical injury. Improper operation or poor force control can damage components or cause personal injury. Manual nut tightening also makes it difficult to precisely control the force and angle, affecting the tightness of the connection between the milling head and the equipment, thereby reducing machining accuracy and equipment performance.

[0015] 1.

Through the cooperation between the limit tube, spring and positioning hole, the milling head can be quickly positioned and installed, reducing the debugging time. It has obvious advantages in batch production and model change production, and can also greatly shorten the downtime for tool changing due to tool wear, process adjustment and other situations, thereby improving equipment utilization; on the other hand, relying on reliable installation structures such as high-precision positioning pins and servo motor-driven automatic centering systems, it can ensure that the position accuracy of the milling head is consistent after each installation, effectively avoid the pole milling size deviation caused by manual installation errors, and ensure that parameters such as pole height, flatness, and verticality meet the standards, thereby improving the consistency and yield rate of lithium battery modules.

Compared with traditional equipment, the present invention achieves double safety protection by cooperating between the first fixed column, the limiting workpiece and the second limiting column. The limiting workpiece realizes the tight closure of the distribution box door through a precise mechanical structure. On the one hand, its rigid constraint can effectively resist the unplanned opening of the door caused by equipment operation vibration or accidental touch, eliminating the risk of electric shock caused by operators accidentally touching live parts from the root, and ensuring personal safety. On the other hand, in the environment where lithium battery production has strict requirements on dust control, the limiting workpiece ensures the sealing performance of the door, builds a dustproof barrier, and avoids metal dust invading the distribution system to cause short circuit faults or abnormal equipment shutdowns, providing reliable protection for the stable operation of the equipment.

[0031] 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.

[0032] like Figures 1 to 12 As shown, an embodiment of the present invention provides a milling device for lithium battery module poles, including a milling device body 1, a head cover 7 fixedly installed inside the milling device body 1, a fixing frame 21 fixedly installed at the bottom of the head cover 7, a mounting plate 24 movably installed inside the fixing frame 21, a milling head 9 fixedly installed at the bottom of the mounting plate 24, and a battery pack 29 movably installed inside the milling device body 1;

[0033] A box body 22 is fixedly installed on the top of the fixed frame 21, a mounting plate 24 is opened inside the mounting plate 24, a limiting tube 26 is movably installed inside the positioning hole 28, a pull rod 23 is fixedly installed on the top of the limiting tube 26, and one end of the pull rod 23 passes through the interior of the box body 22, a spring 27 is fixedly installed between the box body 22 and the limiting tube 26, and a push rod 25 is fixedly installed on the right side of the mounting plate 24.

[0034] The staff selects a suitable milling head 9 according to different models of battery packs 29 and installs it inside the milling equipment body 1. By holding the pull rod 23, the pull rod 23 pulls the limiting tube 26 to move upward inside the fixed frame 21, and squeezes the spring 27 through the limiting tube 26, so that the limiting tube 26 passes through the inside of the fixed frame 21 and enters the inside of the box body 22. Now hold the push rod 25 and slowly push the mounting plate 24 into the inside of the fixed frame 21, and drive the milling head 9 to move synchronously through the mounting plate 24. When the mounting plate 24 completely enters the inside of the fixed frame 21, release the box body 22, and squeeze the limiting tube 26 inside the box body 22 through the spring 27, so that the limiting tube 26 passes through the inside of the fixed frame 21 and enters the inside of the positioning hole 28, and is limited by the limiting tube 26 and the mounting plate 24, thereby completing the installation of the milling head 9.

[0035] In the lithium battery module pole milling equipment, for different types of workpiece battery packs 29, it is necessary to first select an appropriate milling head 9 and place it in the milling equipment body 1 of the equipment; the operator holds the pull rod 23 and lifts it, driving the limit tube 26 to slide upward along the fixed frame 21, and the limit tube 26 squeezes the spring 27 to produce deformation until the end of the slider limit tube 26 passes through the guide rail fixed frame 21 and enters the slot of the positioning sleeve box 22; at this time, the handheld 25 slowly pushes the limit block mounting plate 24 into the guide rail fixed frame 21, and the milling head 9 is driven to move synchronously through the mounting plate 24; when the mounting plate 24 is completely embedded in the fixed frame 21, the box 22 is released, and the spring 27 resets and pushes the slider limit tube 26 to pass through the fixed frame 21 in the opposite direction and enter the lock hole of the limit block mounting plate 24, forming a mechanical interlock, and finally completing the precise installation of the milling head 9. Compared with traditional equipment, this device The coordination between the limiting tube 26, spring 27 and positioning hole 28 facilitates the installation of the milling head 9, significantly improving equipment commissioning and production efficiency while also enhancing processing accuracy and stability. The coordination between the limiting tube 26, spring 27 and positioning hole 28 enables rapid positioning and installation of the milling head 9, reducing commissioning time. This has significant advantages during mass production and model change production, significantly shortening tool change downtime due to tool wear, process adjustments, and other factors, thereby improving equipment utilization. Furthermore, reliable installation structures such as high-precision positioning pins and a servo motor-driven automatic centering system ensure consistent positioning accuracy of the milling head 9 after each installation, effectively avoiding deviations in pole milling dimensions caused by manual installation errors and ensuring that pole height, flatness, verticality and other parameters meet standards, thereby improving the consistency and yield rate of lithium battery modules. The milling size has been increased from 0-800mm to 0-1000mm, making it compatible with 1000mm-long modules that cannot be produced and processed on the market.

A first gear 11 is fixedly installed on one end of the fixed bracket 6, and the first gear 11 and the second gear 12 are meshed with each other.

[0038] The staff needs to open the movable door 2 inside the milling equipment body 1, and then put the battery pack 29 into the milling equipment body 1, then turn on the motor 13, and drive the second gear 12 to rotate inside the fixed bracket 6 through the counterclockwise rotation of the motor 13, and the teeth of the second gear 12 and the first gear 11 are engaged, and the first gear 11 is driven to rotate by the second gear 12, and the bidirectional screw 10 is driven to rotate inside the sleeve block 14 through the first gear 11, so that the sleeve block 14 moves in the slide groove 15 toward one end of the first gear 11, and the connecting block 4 and the movable door 2 are driven to move synchronously through the first gear 11, and then the movable door 2 is unfolded inside the milling equipment body 1, and then the battery pack 29 is put into the interior, and then the motor 13 is turned on clockwise, and the connecting block 4 is driven by the sleeve block 14 to close the movable door 2, thereby completing the unfolding and closing inside the milling equipment body 1.

[0039] When operating inside the milling equipment body 1, the staff needs to open the movable door 2 first, place the battery pack 29 to be processed into the inner cavity of the milling equipment body 1, and then start the motor 13 to run counterclockwise, and make the second gear 12 rotate in the fixed bracket 6 through the gear transmission mechanism, which engages with the first gear 11 to drive the first gear 11 to rotate synchronously; the first gear 11 is spirally advanced in the sleeve block 14 through the bidirectional screw 10, causing the sleeve block 14 to move axially along the slide groove 15 toward the first gear 11. This movement is synchronously transmitted to the connecting block 4 and the movable door 2 through the mechanical linkage mechanism, so that the movable door 2 is smoothly unfolded to the working position in the milling equipment body 1; after the battery pack 29 is fixed, the motor 13 is started in the reverse direction to rotate clockwise, and the sleeve block 14 is driven to move in the opposite direction through the same transmission chain, driving the connecting block 4 to perform the closing action, and finally realizing the precise opening and closing control of the movable door 2 inside the milling equipment body 1, completing Material clamping and processing preparation process; Compared with traditional equipment, this equipment facilitates the expansion and closing of the movable door 2 through the cooperation between the sleeve 14 and the bidirectional screw 10. The design of the movable door 2 that is easy to expand and close significantly improves the operational convenience and safety; In terms of operational convenience, the design simplifies the operating process, allowing operators to quickly complete the opening and closing of the equipment without complicated steps or tools, thereby improving work efficiency; At the same time, the intuitive design of the movable door 2 reduces the skill requirements for the operator, and new employees can also quickly master it, reducing training costs and risks caused by improper operation, effectively preventing accidental opening or closing of the equipment during operation, and avoiding safety hazards caused by accidental touch or vibration; In addition, the movable door 2 is tightly closed to form a sealed environment to prevent the intrusion of impurities such as dust and cutting fluid, protect the accuracy and stability of the equipment, and reduce the interference of noise and vibration on the operator.

[0040] Among them, a distribution box door 30 is movably installed on the right side of the milling equipment body 1, and a first fixed column 17 is fixedly installed on the right side of one distribution box door 30. A limiting workpiece 18 is movably installed on the outer surface of the first fixed column 17. A second limiting column 19 is fixedly installed on the right side of the other distribution box door 30. A snap-fit ​​groove 31 is opened inside the limiting workpiece 18, and the inside of the snap-fit ​​groove 31 is snapped on the outer surface of the second limiting column 19.

[0041] When the staff is using the inside of the milling equipment body 1, they need to close the distribution box door 30 by holding the two distribution box doors 30 and rotating them inside the milling equipment body 1. When the two distribution box doors 30 are in contact with the inside of the milling equipment body 1, then, hold the limiting workpiece 18 and rotate it on the outer surface of the first fixed column 17 until the internal engaging groove 31 of the limiting workpiece 18 is engaged with the inside of the first fixed column 17, and then the limiting workpiece 18 stops rotating, thereby completing the closing of the two distribution box doors 30.

[0042] When operating inside the milling device body 1, it is necessary to first hold the two-component distribution box door 30 and rotate it until it is completely in contact with the inner wall of the milling device body 1 to achieve preliminary closure. Then the rotating component limiting workpiece 18 rotates along the outer surface of the first fixed column 17, and stops rotating when the buckle snap-fit ​​groove 31 in the limiting workpiece 18 engages with the internal structure of the first fixed column 17, and completes the firm closure of the two distribution box doors 30 through double mechanical locking, ensuring the safe operation of the equipment; compared with traditional equipment, this equipment achieves the tight closure of the distribution box door 30 through the precision mechanical structure of the limiting workpiece 18 through the cooperation between the first fixed column 17, the limiting workpiece 18 and the second limiting column 19, forming double safety protection; on the one hand, its rigid constraint can effectively resist the unplanned opening of the door body caused by the vibration of the equipment operation or accidental touch, and eliminate the risk of electric shock of the operator accidentally touching the live parts from the root, thereby ensuring personal safety; on the other hand, in the environment where lithium battery production has strict requirements on dust control, the limiting workpiece 18 ensures the sealing performance of the door body, builds a dustproof barrier, and prevents metal dust from invading the distribution system to cause short circuit faults or abnormal shutdown of equipment, providing reliable guarantee for the stable operation of the equipment.

[0043] A base 3 is fixedly installed on the bottom of the milling equipment body 1 , and a support base 8 is fixedly installed on the bottom of the base 3 .

[0044] Since the bottom of the milling equipment body 1 is fixedly installed with a base 3, and the bottom of the base 3 is fixedly installed with a support base 8, the cooperation between the base 3 and the support base 8 facilitates providing stable support for the milling equipment body 1 and reduces the stability of the milling equipment body 1 during use.

[0045] The distribution box door 30 is provided with heat dissipation holes 20 in a linear array.

[0046] Since the heat dissipation holes 20 are in the form of a linear array inside the distribution box door 30, it is convenient to dissipate heat inside the milling equipment body 1, thereby ensuring the temperature stability of the milling equipment body 1 during use.

[0047] A support base 16 is fixedly mounted on the left side of the fixing bracket 6 , and the interior of the support base 16 is U-shaped.

[0048] Since the interior of the support seat 16 is in a U-shape on the left side of the fixing bracket 6 , it is convenient to provide stable support for the motor 13 , thereby reducing the stability of the motor 13 during operation and improving the efficiency of the motor 13 .

[0049] The outer diameter of the mounting plate 24 is equal to the inner diameter of the fixing frame 21 , and the interior of the fixing frame 21 has a smooth surface design.

[0050] Since the outer diameter of the mounting plate 24 is equal to the inner diameter of the fixed frame 21 and the interior of the fixed frame 21 has a smooth design, it is convenient to hold the push rod 25 and slowly push the mounting plate 24 into the interior of the fixed frame 21, thereby ensuring the installation efficiency of the milling head 9 pair.

[0051] The sleeve blocks 14 and the connecting blocks 4 are arranged in pairs, and there are two groups in total that move inside the fixing bracket 6 .

[0052] Since the sleeve blocks 14 and the connecting blocks 4 are grouped in pairs, there are two groups of movable blocks inside the fixed bracket 6. Through the cooperation between the sleeve blocks 14 and the connecting blocks 4, the movable door 2 is easily opened and closed, ensuring the efficiency of the opening and closing of the movable door 2.

[0053] Working principle and usage process:

[0054] The staff selects a suitable milling head 9 according to different models of battery packs 29 and installs it inside the milling equipment body 1. By holding the pull rod 23, the pull rod 23 pulls the limiting tube 26 to move upward inside the fixed frame 21, and squeezes the spring 27 through the limiting tube 26, so that the limiting tube 26 passes through the inside of the fixed frame 21 and enters the inside of the box body 22. Now hold the push rod 25 and slowly push the mounting plate 24 into the inside of the fixed frame 21, and drive the milling head 9 to move synchronously through the mounting plate 24. When the mounting plate 24 completely enters the inside of the fixed frame 21, release the box body 22, and squeeze the limiting tube 26 inside the box body 22 through the spring 27, so that the limiting tube 26 passes through the inside of the fixed frame 21 and enters the inside of the positioning hole 28, and is limited by the limiting tube 26 and the mounting plate 24, thereby completing the installation of the milling head 9.

[0055] The staff needs to open the movable door 2 inside the milling equipment body 1, and then put the battery pack 29 into the milling equipment body 1, then turn on the motor 13, and drive the second gear 12 to rotate inside the fixed bracket 6 through the counterclockwise rotation of the motor 13, and the teeth of the second gear 12 and the first gear 11 are engaged, and the first gear 11 is driven to rotate by the second gear 12, and the bidirectional screw 10 is driven to rotate inside the sleeve block 14 through the first gear 11, so that the sleeve block 14 moves in the slide groove 15 toward one end of the first gear 11, and the connecting block 4 and the movable door 2 are driven to move synchronously through the first gear 11, and then the movable door 2 is unfolded inside the milling equipment body 1, and then the battery pack 29 is put into the interior, and then the motor 13 is turned on clockwise, and the connecting block 4 is driven by the sleeve block 14 to close the movable door 2, thereby completing the unfolding and closing inside the milling equipment body 1.

[0056] When the staff is using the inside of the milling equipment body 1, they need to close the distribution box door 30 by holding the two distribution box doors 30 and rotating them inside the milling equipment body 1. When the two distribution box doors 30 are in contact with the inside of the milling equipment body 1, then, hold the limiting workpiece 18 and rotate it on the outer surface of the first fixed column 17 until the internal engaging groove 31 of the limiting workpiece 18 is engaged with the inside of the first fixed column 17, and then the limiting workpiece 18 stops rotating, thereby completing the closing of the two distribution box doors 30.
