Description

Technical Field

[0001] This invention relates to the technical field of battery casing processing, and in particular to a processing mechanism for aluminum battery casings. Background Technology

[0002] With the rapid development of the new energy industry, aluminum battery casings have been widely used in power batteries and energy storage systems due to their lightweight, high specific strength, excellent thermal conductivity, and corrosion resistance. These casings are usually made of multiple aluminum plates that are stamped, bent, and then welded together. Welding is a key process to ensure the structural sealing and overall strength. However, during the welding process, weld marks such as raised weld scars, oxidation color differences, and uneven surfaces will inevitably form in the weld area. These marks not only affect the appearance of the casing but may also become stress concentration points, interfering with subsequent painting or assembly processes. Therefore, after welding is completed, the weld seam needs to be ground and cleaned to obtain a smooth and flat surface.

[0003] Currently, the industry still relies heavily on manual labor for grinding and cleaning the weld seams of aluminum battery casings. Since the weld seams of these casings are mostly located at the joints of two aluminum plates that are perpendicular or at a certain angle, the grinding tool must be operated at a specific tilt angle along the tangent of the weld seam. This requires a high level of skill and stability from the operators. Traditional manual grinding methods have disadvantages such as high labor intensity, low efficiency, and difficulty in matching the production rhythm of automated welding production lines. At the same time, the grinding quality depends on the worker's experience, resulting in poor consistency and the tendency to over-grind or under-grind, which affects the uniformity of the casing wall thickness and the structural integrity. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an aluminum battery casing processing mechanism, the specific technical solution of which is as follows: An aluminum battery casing processing mechanism of the present invention includes a guiding unit, a grinding unit, and a movable table connecting the guiding unit and the grinding unit. The guiding unit drives the grinding unit to move along a predetermined trajectory, and the grinding unit grinds the welding positions on the casing. The guide unit includes two long plates that are relatively inclined and two sliding columns installed on the side wall of the movable platform. The sliding columns move on one of the long plates or between the two long plates. An electromagnet is provided in the long plate and a permanent magnet that cooperates with the electromagnet is provided in the sliding column. At least one of the two electromagnets is energized.

[0005] Furthermore, the guide unit also includes an arc-shaped sleeve and two arc-shaped adjusting arms that slide through both ends of the arc-shaped sleeve. The two arc-shaped adjusting arms are respectively connected to the two long plates, and the center of the movement trajectory of the arc-shaped adjusting arms on the arc-shaped sleeve coincides with the docking position of the two long plates.

[0006] Furthermore, a T-shaped frame is vertically slidably arranged on the arc-shaped sleeve, and the T-shaped frame is fastened to the arc-shaped sleeve by a set screw. A long groove is horizontally opened on the T-shaped frame, and two synchronous shafts, respectively connected to the two arc-shaped adjusting arms, are slidably arranged in the long groove.

[0007] Furthermore, the polishing unit includes two relatively distributed drive wheels, a drive chain driven on the two drive wheels, and a plurality of polishing plates disposed on the drive chain. When the polishing plates follow the drive chain in a linear motion, adjacent polishing plates abut against each other and combine to form a combined polishing surface, which is used to polish the outer shell.

[0008] Furthermore, the polishing unit also includes a support platform connected to the movable table and an annular groove disposed on the support platform and having the same shape as the transmission chain, wherein the cross-sectional shape of the annular groove is square; The bottom of the grinding plate is provided with a connecting plate, the end of which extends into the annular groove. At least three horizontal rollers and at least three vertical rollers are provided on the connecting plate. The three horizontal rollers and the three vertical rollers are arranged in a triangular pattern. The horizontal rollers and the vertical rollers are used in conjunction with the corresponding surfaces of the inner wall of the annular groove.

[0009] Furthermore, the annular groove is composed of two relatively distributed straight grooves and two relatively distributed arc grooves. At least one of the two straight grooves can move vertically on the support platform, and the arc grooves undergo elastic deformation following the movement of the straight grooves. A slide block is slidably disposed on the side wall of the grinding plate, and a secondary plate is rotatably disposed on the slide block. The secondary plate is fixedly connected to the transmission chain.

[0010] Furthermore, the inner wall of the arc-shaped groove is provided with slopes and grooves on both the upper and lower sides, and the transverse roller is composed of a conical column and a cylindrical column that are used in conjunction with the slopes and the grooves, respectively.

[0011] Furthermore, two damping units are provided on the support platform corresponding to the two linear slots. The damping units are used to provide damping force for the several grinding plates moving on the linear slots. The damping unit includes a rotating cylinder, which is rotatably mounted on the support platform via a fixed frame. A damping wheel is mounted on the rotating cylinder and is connected to each of the grinding plates. Several magnetic blocks are mounted on the inner wall of the rotating cylinder. A fixed sleeve is coaxially mounted inside the rotating cylinder and is fixed to the fixed frame via a fixed frame. A coil that works with the magnetic blocks is mounted on the fixed sleeve. A movable iron core is slidably mounted inside the fixed sleeve, with its end extending beyond the fixed sleeve. A pressing plate that frictionally engages with the end face of the rotating cylinder is mounted on the movable iron core.

[0012] The beneficial effects of this invention are as follows: By using a guiding unit to guide the movement trajectory of the grinding unit, the movement trajectory of the grinding unit can be made V-shaped. The two sides of the V-shaped movement trajectory are planar movements corresponding to the surfaces of the two aluminum plates on the outer shell, and the middle area of ​​the V-shaped movement trajectory is arc-shaped. This allows the welding position to be ground into a regular arc shape, improving the flatness of the grinding and facilitating a smooth transition of the ground welding position to the surface of the aluminum plate, thereby improving the grinding quality. Using automatic grinding can greatly reduce manpower consumption, simplify operation, and improve work efficiency. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 9As shown, an aluminum battery casing processing mechanism of the present invention includes a guide unit 1, a grinding unit 2, and a movable table 6 connecting the guide unit 1 and the grinding unit 2. The guide unit 1 drives the grinding unit 2 to move along a predetermined trajectory, and the grinding unit 2 grinds the welding position on the casing 3. The guide unit 1 includes two long plates 4 that are relatively inclined and two sliding columns 5 installed on the side wall of the movable platform 6. The sliding column 5 moves on one of the long plates 4 or between the two long plates 4. An electromagnet is provided in the long plate 4 and a permanent magnet that works in conjunction with the electromagnet is provided in the sliding column 5. At least one of the two electromagnets is energized.

[0019] In this invention, when only the grinding unit 2 is used, the grinding unit 2 can perform static grinding on the outer shell 3. At this time, the grinding surface on the outer shell 3 is at a specific angle, that is, the welding position after grinding is in the shape of a plane or an inclined plane. The guide unit 1 can drive the grinding unit 2 to move along a specific trajectory, so that the grinding unit 2 can move from one aluminum plate position on the outer shell 3 through the welding position and then to another aluminum plate position. Thus, the movement trajectory of the grinding unit 2 is arc-shaped. At this time, the grinding unit 2 can perform grinding on all welding positions between the two aluminum plates, and the weld seam is in a regular arc shape after grinding. This not only improves the comprehensiveness of grinding and avoids the weld points near the aluminum plate not being effectively ground when only flat or inclined grinding is performed, but also makes the grinding surface and the aluminum plate smoother.

[0020] To improve the operational stability of the grinding unit 2, the guide unit 1 can be configured into two sets, with the two sets of guide units 1 respectively located on the front and rear sides of the movable table 6. This allows the two sets of guide units 1 to simultaneously drive the grinding unit 2 through the movable table 6. The two long plates 4 can form an upward-facing angle. The sliding column 5 is attracted to the corresponding long plate 4 via a permanent magnet and an electromagnet. When the sliding column 5 moves, it remains in contact with the long plate 4, ensuring that the sliding column 5 can only move on the long plate 4 and preventing it from separating from it. The movement trajectories of the two sliding columns 5 and the two long plates 4 allow the two sliding columns 5 to... The sliding column 5 can only move in a straight line on the corresponding long plate 4, or it can move from one long plate 4 to another long plate 4 along the trajectory formed by the two long plates 4. In order to achieve smooth movement of the sliding column 5 between the two long plates 4, when the sliding column 5 moves from one long plate 4 to the position between the two long plates 4, the electromagnet in the long plate 4 is de-energized, and the sliding column 5 attracts the electromagnet in the other long plate 4, thereby enabling the sliding column 5 to transfer its position. Of course, even if the electromagnet in the long plate 4 is not de-energized, the sliding column 5 can still achieve a smooth transition between the two long plates 4 due to the way the two sliding columns 5 are set.

[0021] In use, the outer casing 3 can be transported horizontally via an external conveying mechanism, with the welding position on the outer casing 3 facing the grinding unit 2, pushing the movable table 6 to move. The movable table 6 drives the two sliding columns 5 to move on the two long plates 4. The two long plates 4 and the two sliding columns 5 can guide the movement trajectory of the movable table 6 and the grinding unit 2. Initially, the two sliding columns 5 can be located on the left long plate 4. As the movable table 6 moves, the two sliding columns 5 slide on the left long plate 4. At this time, the movable table 6 and the grinding unit 2 move in a straight line, and the movement trajectory of the grinding unit 2 corresponds to the plane of an aluminum plate on the outer casing 3. When the right sliding column 5 moves between the two long plates 4 and transfers to the other long plate 4, the grinding unit 2 gradually changes from an inclined state to a horizontal state. During this process, the grinding unit 2 gradually shifts its grinding position on the outer shell 3 from the outer surface of one aluminum plate to the bottom of the welding position between the two aluminum plates. The grinding unit 2 completes the grinding of half of the welding position between the two aluminum plates. Then, the movable table 6 continues to move. When the left sliding column 5 moves from the left long plate 4 to the right long plate 4, the grinding unit 2 completes the grinding of the other half of the welding position. At this time, the movement trajectory of the grinding unit 2 corresponds to the surface of the other aluminum plate, thus completing one grinding process of the outer shell 3 by the grinding unit 2. The welded position after grinding is in a regular arc shape. With the reciprocating motion of the movable table 6 and the lateral feed of the outer shell 3, the grinding unit 2 can achieve full grinding of the welding position on the outer shell 3.

[0022] By using the guide unit 1 to guide the movement trajectory of the grinding unit 2, the movement trajectory of the grinding unit 2 can be made V-shaped. The two sides of the V-shaped movement trajectory are planar movements corresponding to the surfaces of the two aluminum plates on the outer shell 3, and the middle area of ​​the V-shaped movement trajectory is arc-shaped. This allows the welding position to be ground into a regular arc shape, improving the flatness of the grinding and facilitating a smooth transition of the ground welding position to the surface of the aluminum plate, thereby improving the grinding quality. Using automatic grinding can greatly reduce manpower consumption, simplify the operation, and improve work efficiency.

[0023] Furthermore, the guide unit 1 also includes an arc-shaped sleeve 7 and two arc-shaped adjusting arms 8 that slide through both ends of the arc-shaped sleeve 7. The two arc-shaped adjusting arms 8 are respectively connected to the two long plates 4, and the center of the movement trajectory of the arc-shaped adjusting arms 8 on the arc-shaped sleeve 7 coincides with the docking position of the two long plates 4.

[0024] When grinding is required at the welding positions of aluminum plates of different thicknesses, or when the grinding curvature needs to be adjusted, the movement trajectory of the two sliding columns 5 and the grinding unit 2 can be adjusted by adjusting the included angle between the two long plates 4. Specifically, for example... Figure 2As shown, the arc sleeve 7 and the arc adjusting arm 8 are coaxially arranged. When the long plate 4 slides on the arc sleeve 7 through the arc adjusting arm 8, the included angle between the two long plates 4 can be changed. Furthermore, by setting the center position of the movement trajectory of the arc adjusting arm 8, the two long plates 4 can always remain in a docked state, thus preventing the gap between the two long plates 4 from interfering with the movement of the sliding column 5 when they separate.

[0025] Furthermore, a T-shaped frame 9 is vertically slidably arranged on the arc sleeve 7, and the T-shaped frame 9 and the arc sleeve 7 are fastened together by a set screw. A long groove 10 is horizontally opened on the T-shaped frame 9, and two synchronous shafts 11, which are respectively connected to the two arc-shaped adjusting arms 8, are slidably arranged in the long groove 10.

[0026] The center line of the included angle between the two long plates 4 is vertical, and the center line coincides with the axis of the arc sleeve 7 and the movement trajectory of the T-shaped frame 9. When the T-shaped frame 9 slides on the arc sleeve 7, the T-shaped frame 9 can drive the two arc-shaped adjusting arms 8 to move synchronously through the long groove 10 and the two synchronous shafts 11. Since the movement trajectory of the arc-shaped adjusting arm 8 is arc-shaped, the synchronous shaft 11 will slide in the long groove 10, thereby synchronously adjusting the position of the two long plates 4, so that the two long plates 4 always maintain a corresponding relationship, and it is convenient to locate the center line between the two long plates 4.

[0027] Furthermore, the polishing unit 2 includes two relatively distributed transmission wheels 12, a transmission chain 13 driven on the two transmission wheels 12, and several polishing plates 14 disposed on the transmission chain 13. When the polishing plates 14 follow the transmission chain 13 to move in a straight line, two adjacent polishing plates 14 abut against each other and combine to form a combined polishing surface. The combined polishing surface is used to polish the outer shell 3.

[0028] Two drive wheels 12 are distributed left and right, and the line connecting the two drive wheels 12 is perpendicular to the direction of movement of the outer shell 3. When the two drive wheels 12 move, they will drive the drive chain 13 and several grinding plates 14 to move synchronously. The straight area on the drive chain 13 corresponds to the welding position on the outer shell 3. Thus, the grinding plates 14 in the two straight areas on the drive chain 13 can achieve a bidirectional and synchronous grinding mode on the welding position on the outer shell 3. The grinding plates 14 follow the rotation of the drive chain 13 to achieve a continuous grinding mode, improving the continuity of the grinding process. The combined grinding surface composed of several grinding plates 14 in the straight area on the drive chain 13 can grind the welding position on the outer shell 3. The setting of this combined grinding surface can make the relative movement speed of different positions on it and the welding position the same, achieving a positive grinding effect. The cyclic transmission of several grinding plates 14 can keep the combined grinding surface always present and perform long-term grinding work. The abutting setting between two adjacent grinding plates 14 can avoid the gaps between them from affecting the grinding effect on the outer shell 3.

[0029] Furthermore, the grinding unit 2 also includes a support platform 15 connected to the movable table 6 and an annular groove 16 disposed on the support platform 15 and having the same shape as the transmission chain 13. The cross-sectional shape of the annular groove 16 is square. A connecting plate 17 is provided at the bottom of the grinding plate 14. The end of the connecting plate 17 extends into the annular groove 16. At least three horizontal rollers 18 and at least three vertical rollers 19 are provided on the connecting plate 17. The three horizontal rollers 18 and the three vertical rollers 19 are all triangularly distributed. The horizontal rollers 18 and the vertical rollers 19 are used in conjunction with the corresponding surfaces of the inner wall of the annular groove 16.

[0030] The movable platform 6 supports the support platform 15, which in turn supports the annular groove 16 and its upper structure. The opening of the annular groove 16 faces upward. Since the cross-sectional shape of the annular groove 16 is square, the opening of the annular groove 16 occupies part of the upper area of ​​the square. Because the square has four faces, the three horizontal rollers 18 can be staggered to contact the upper and lower faces of the square, thus limiting the connection plate 17 in the vertical direction. In the horizontal direction, the staggered arrangement of the three vertical rollers 19 can contact the left and right faces of the square, thus limiting the connection plate 17 in four directions. Therefore, this structure is used to guide and support the grinding plate 14. Figure 5 For example, three vertical rollers 19 and four horizontal rollers 18 can be set, as long as they can be used in conjunction with the four faces of the square.

[0031] Furthermore, the annular groove 16 is composed of two relatively distributed straight grooves 20 and two relatively distributed arc grooves 21. At least one of the two straight grooves 20 can move vertically on the support platform 15, and the arc groove 21 undergoes elastic deformation as it moves with the straight groove 20. A slide block 26 is slidably disposed on the side wall of the grinding plate 14, and a secondary plate 27 is rotatably disposed on the slide block 26. The secondary plate 27 is fixedly connected to the transmission chain 13.

[0032] In its natural state, the two straight grooves 20 are located on the same horizontal plane. At this time, the grinding plates 14 inside the two straight grooves 20 can achieve a bidirectional grinding effect on the welding position on the outer shell 3. When there is a requirement for the grinding direction, the two straight grooves 20 can be staggered in the vertical direction, that is, the two straight grooves 20 are distributed in a high-low manner. The grinding plates 14 on the straight groove 20 at the higher position can grind the welding position on the outer shell 3, while the grinding plates 14 on the straight groove 20 at the lower position will be separated from the outer shell 3. When the two straight grooves 20 are moved in a staggered manner, the two ends of the arc groove 21 will be distributed in a high-low manner. At this time, the shape of the arc groove 21 changes. In order to avoid tearing of the arc groove 21, the arc groove 21 can be made of elastic plastic or other materials with variable functions, so that the arc groove 21 can maintain its original guiding function. The arc groove 21 and the support platform 15 can be fastened together by bolts.

[0033] When the two straight grooves 20 are misaligned in the vertical direction, the grinding plate 14 and the transmission chain 13 will move relative to each other. At this time, the normal connection between the grinding plate 14 and the transmission chain 13 can be achieved by using the slide 26 and the auxiliary plate 27, ensuring that the transmission chain 13 provides the moving power for the grinding plate 14 while allowing the grinding plate 14 to move on the annular groove 16.

[0034] Furthermore, the inner walls of the arc-shaped groove 21 are provided with slopes 22 and grooves 23 on both the upper and lower sides, and the transverse roller 18 is composed of a conical column 24 and a cylindrical column 25 that are used in conjunction with the slopes 22 and grooves 23 respectively.

[0035] When the grinding plate 14 moves on the straight groove 20, it moves in a straight line. At this time, the vertical roller 19 and the cylinder 25 can cooperate with the inner wall of the straight groove 20. When the grinding plate 14 moves on the arc groove 21, its movement trajectory is arc-shaped. At this time, the vertical roller 19 can still move normally, while different positions on the horizontal roller 18 will generate relative friction with the inner wall of the arc groove 21. To avoid this phenomenon, the horizontal roller 18 can be combined with the conical column 24 and the cylinder 25. The cylinder 25 cooperates with the straight groove 20, and the conical column 24 cooperates with the slope 22 in the arc groove 21. The cylinder 25 is located in the groove 23. At this time, the cylinder 25 and the arc groove 21 are separated. This allows different positions on the conical column 24 to move synchronously with different positions on the slope 22, avoiding relative friction.

[0036] It should be noted that when the slope 22 is located inside the groove 23, the cone 24 is located on the connecting plate 17 near the transmission chain 13, and the cone direction of the cone 24 needs to correspond to the slope 22. When the slope 22 is located outside the groove 23, the cone 24 is located on the connecting plate 17 away from the transmission chain 13, and the cone direction of the cone 24 still needs to correspond to the slope 22. Of course, the tilt direction of the slope 22 needs to cooperate with the cone 24. In actual use, the cone 24 needs to be set according to the position of the slope 22 and its tilt direction, and multiple installation modes can be selected. As long as the purpose of this case can be achieved, it is within the protection scope of this case.

[0037] Furthermore, two damping units 28 are provided on the support platform 15 corresponding to the two straight grooves 20. The damping units 28 are used to provide damping force for the several grinding plates 14 moving on the straight grooves 20. The damping unit 28 includes a rotating cylinder 29, which is rotatably mounted on the support platform 15 via a fixing frame 30. A damping wheel 31 is mounted on the rotating cylinder 29 and is connected to each grinding plate 14 via a transmission. Several magnetic blocks 32 are mounted on the inner wall of the rotating cylinder 29. A fixed sleeve 33 is coaxially mounted inside the rotating cylinder 29 and is fixed to the fixing frame 30 via a fixing frame 34. A coil 35 that works with the magnetic blocks 32 is mounted on the fixed sleeve 33. A movable iron core 36 is slidably mounted inside the fixed sleeve 33. The end of the movable iron core 36 extends beyond the fixed sleeve 33, and a pressing plate 37 that rubs against the end face of the rotating cylinder 29 is mounted on the movable iron core 36.

[0038] In order to make the several grinding plates 14 on the straight groove 20 abut against each other and form a combined grinding surface, the damping unit 28 can be used to provide damping force for the movement of the grinding plates 14, thereby eliminating the gap between adjacent grinding plates 14. The combined grinding surface has better integrity and higher flatness.

[0039] When the grinding plate 14 moves, it drives the damping wheel 31 to rotate. The damping wheel 31 drives the rotating drum 29 and the magnetic block 32 to rotate. The magnetic block 32 moves relative to the coil 35. An induced current is generated inside the coil 35. Using the principle of electromagnetic induction, the induced current in the coil 35 will reverse and resist the rotation of the damping wheel 31, thereby providing damping force for the movement of the grinding plate 14. At the same time, when an induced current is generated inside the coil 35, based on the shape of the coil 35, an induced magnetic force is also generated inside it. This magnetic force can provide attraction for the movable iron core 36, causing the movable iron core 36 to move towards the inside of the fixed sleeve 33. The movable iron core 36 drives the pressing plate 37 to press the end face of the rotating drum 29. Thus, the pressing plate 37 provides damping force for the rotation of the rotating drum 29 and the damping wheel 31. This damping force is also transmitted to the grinding plate 14, so that the grinding plate 14 can be subjected to a double damping effect.

[0040] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
