Description

Technical Field

[0001] This invention relates to the field of cleaning mechanism technology, specifically to a cleaning mechanism for the aluminum cover plate poles of new energy power batteries. Background Technology

[0002] Terminals are components in a battery pack that connect to one terminal of an adjacent individual cell. Typically, one end is directly connected to the busbar, while the other end is either connected to an external conductor or to one terminal of an adjacent individual cell within the battery pack. Terminals play a crucial connection role in the battery system, ensuring smooth current flow. As a key component of a power battery, the terminals connect the positive and negative electrodes, and their surface cleanliness significantly impacts battery performance and safety. The presence of dirt, grease, oxides, or other impurities on the terminal surface can affect the battery's stability and safety during charging and discharging.

[0003] Before a battery is assembled into a complete battery, the terminals need to be cleaned multiple times. Before welding with the aluminum cover plate, the terminals themselves need to be cleaned to remove impurities and oxides. After welding, a routine post-weld cleaning process is also required to remove impurities and oxides generated during the welding process, so that there are no impurities between the terminals and the aluminum cover plate. In the existing technology, the cleaning of the terminals and aluminum cover plate after welding is divided into manual and mechanical methods. Manual cleaning is time-consuming and labor-intensive, while mechanical cleaning is less efficient and is prone to incomplete cleaning, leaving welding residues. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a cleaning mechanism for aluminum cover plates and electrode posts of new energy power batteries to solve the problems mentioned in the background. The present invention has a novel structure, in which welded parts are sequentially placed into the track assembly, and the clamping blocks push them to move along the gap between the inner and outer tracks, cleaning the surfaces of the aluminum cover plates and electrode posts separately from the bottom and top, respectively, thereby improving the cleaning effect. Furthermore, the device can cycle through multiple batches of aluminum cover plates and electrode posts for cleaning, thereby improving cleaning efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cleaning mechanism for aluminum cover plates and electrode posts of new energy power batteries, comprising a cleaning box, one end of which has an inlet and outlet, and a door rotatably mounted on the top of the cleaning box. The cleaning box contains a track assembly, which includes an inner track and an outer track at the outer end of the inner track. A gap exists between the inner and outer tracks. Welded components are equidistantly slidably inserted into the gap between the inner and outer tracks, and these welded components are composed of an aluminum cover plate and electrode posts welded together. The outer track has an opening corresponding to the inlet and outlet. The two sides of the inner and outer tracks are fixed to the inner wall of the cleaning box. Two sprockets are symmetrically arranged on the inner side of the inner track. The cleaning assembly is installed inside the cleaning box via a rotating shaft. A first motor is fixed at the position of a sprocket on one side of the outer end of the cleaning box, and the output end of the first motor is fixedly connected to the sprocket. An upper cleaning assembly is provided on both sides of the top of the outer ring track, and a lower cleaning assembly is provided at the bottom of the outer ring track. The upper cleaning assembly includes a connecting frame. A first shaft is rotatably installed inside the connecting frame via a bearing. Three rows of cleaning frames are equidistantly installed on the surface of the first shaft, and the cleaning frames are semi-circular frames wrapped around the electrode post surface of the welded part. The lower cleaning assembly includes a mounting frame. Two sets of mounting frames are symmetrically provided at the bottom of the outer ring track, and a second shaft is rotatably installed on the top of the mounting frame. Three brush plates are equidistantly installed on the surface of the second shaft.

[0006] Furthermore, the track assembly also includes a limiting plate, with the limiting plate fixed at the upper end of the opening of the outer ring track, and a delivery plate fixed at the bottom of the limiting plate, and a delivery plate fixed at the lower end of the opening of the outer ring track.

[0007] Furthermore, chains are meshed on the outer surfaces of the two sprockets, a movable notch is provided on the surface of the inner track, clamping blocks are fixed at equal intervals on the chain, and welded parts are clamped on the surface of the clamping blocks that protrude from the movable notch.

[0008] Furthermore, a dust collection box is provided in the middle of the inner ring track, two sprockets are rotatably installed at both ends of the dust collection box, and a dust suction port is opened on the top of the dust collection box. A dust collection device is installed inside the dust collection box, and one side of the dust collection box is connected to the outside through an air pipe.

[0009] Furthermore, the upper cleaning assembly also includes a toothed ring fixed to the bottom of the cleaning frame, and the toothed ring is rotatably mounted on the outer surface of the first shaft. The toothed ring and the cleaning frame have corresponding through holes. A rack is slidably inserted into the periphery of the first shaft corresponding to the position of each row of toothed rings. The toothed ring and the rack are meshed and connected, and the two ends of the rack slide through the two ends of the connecting frame through bearings.

[0010] Furthermore, the lower cleaning assembly also includes a bottom frame. The bottom of the mounting frame is provided with a bottom frame, and spring telescopic rods are fixed at the four corners of the bottom of the dust collection box corresponding to the bottom frame. The extended ends of the spring telescopic rods are fixedly connected to the bottom frame.

[0011] Furthermore, two vertical plates are symmetrically fixed on the outer side of the connecting frame, and the bottom of the vertical plates is rotatably connected to a connecting rod via a pivot. The other end of the connecting rod is rotatably connected to the bottom frame via a pivot. Electric push rods are fixed at equal intervals on the inner wall of the cleaning box corresponding to the positions of the vertical plates, and the extended end of the electric push rod is fixedly connected to the vertical plate.

[0012] Furthermore, a slide rail is fixed on the surface of the bottom frame located between the two sets of mounting brackets, and a screw device is installed inside the slide rail. The two sets of mounting brackets are engaged with the screw device and slide along the slide rail.

[0013] Furthermore, the mounting bracket has a sliding groove on its side, and a side plate is slidably inserted into the sliding groove. A transmission belt is installed between the top of the side plate and the mounting bracket. One end of the transmission belt pulley is fixedly connected to the second shaft. A connecting shaft is rotatably installed on the top of the side plate through a bearing, and the other end of the transmission belt pulley is fixed to the connecting shaft. A moving groove is opened on the surface of the side plate. A limiting post is slidably connected in the moving groove, and the limiting post is in contact with the belt on one side of the transmission belt. A return spring is fixed between the moving groove and the limiting post.

[0014] Furthermore, a turntable is fixed to one end of the rack near the connecting shaft, and an insert block is fixed on the surface of the turntable. A slot is provided on the connecting shaft corresponding to the position of the insert block, and the insert block can be slidably inserted into the slot.

[0015] The beneficial effects of this invention are:

[0016] 1. When the connecting frame is moved horizontally by the electric push rod, the plug can be inserted into the slot to complete the connection between the turntable and the connecting shaft. At this time, the transmission belt can simultaneously drive the rotation of the first shaft and the second shaft, thereby completing the replacement of the cleaning frame and brush plate. This avoids the cleaning effect caused by a lot of impurities on the cleaning frame and brush plate after long-term use. Before replacement, the cleaning frame and brush plate need to be moved away from the surface of the welded parts. At the same time, the mounting frame can be moved back and forth by the drive of the screw device inside the slide rail of the bottom frame, which can also drive the rack to move back and forth and mesh with the toothed ring. When the wiping plate moves back and forth, it will wipe the bottom surface of the aluminum cover plate of the welded parts. When the toothed ring rotates, the cleaning frame rotates to clean the surface of the pole post.

[0017] 2. In this invention, when the vertical plate is moved by the electric push rod, the bottom connecting rod of the vertical plate adjusts the position of the bottom frame by rotation. When the vertical plate moves the cleaning frame towards the pole post, the bottom frame also moves upward. When the cleaning frame wraps around the surface of the pole post, the brush plate also presses against the surface of the aluminum cover plate, thereby cleaning the surface of the aluminum cover plate and the pole post of the welded part. When the vertical plate moves outward, the cleaning frame will detach from the pole post. Under the action of the spring telescopic rod, the bottom frame is pushed downward, moving the brush plate away from the aluminum cover plate, so as not to interfere with the movement of the welded part along the inside of the track assembly, making it convenient to replace it for the next batch of processing.

[0018] 3. This invention separates the upper and lower ends of the track by using a dust collection box to prevent debris generated during cleaning at the upper end from falling to the lower end. The debris is collected through the suction port and can be cleaned by opening the box door.

[0019] 4. In this invention, after the welded parts are fed into the feed plate, they enter the gap between the outer and inner ring tracks. At this time, the clamping block moves to the back of the welded parts and clamps and fixes them, and pushes them to move. The welded parts are fed in alternately in this way. After the welded parts are cleaned, they are sent out from the top and sent out from the delivery plate through the guide of the limiting plate, which is convenient for manual collection. The first motor drives the sprocket to rotate, and the chain drives the clamping block to push multiple sets of welded parts, and the cleaning is completed alternately.

[0020] 5. Compared with the prior art, the present invention places the welded parts into the track assembly in sequence, and pushes them along the gap between the inner and outer tracks by the clamping blocks, so as to clean the surface of the aluminum cover plate and the surface of the pole separately from the bottom and the top, thereby improving the cleaning effect. In addition, the device can clean multiple batches of aluminum cover plates and poles in a cycle, thereby improving the cleaning efficiency. Attached Figure Description

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] Please see Figures 1 to 10This invention provides a technical solution: a cleaning mechanism for aluminum cover plates and electrode posts of new energy power batteries, including a cleaning box 1. One end of the cleaning box 1 has an inlet / outlet 11, and a door 12 is rotatably installed on the top of the cleaning box 1. A track assembly 2 is provided inside the cleaning box 1. The track assembly 2 includes an inner track 23, and an outer track 24 at the outer end of the inner track 23. A gap is provided between the inner track 23 and the outer track 24. The inner track 23 and the outer track 24 slide at equal distances at the gap. A welded component 3 is connected to the cleaning box 1. The welded component 3 is composed of an aluminum cover plate and an electrode post. The outer ring track 24 has an opening corresponding to the position of the inlet / outlet 11. The inner ring track 23 and the outer ring track 24 are fixed to the inner wall of the cleaning box 1 on both sides. Two sprockets 26 are symmetrically arranged on the inner side of the inner ring track 23. The sprockets 26 are installed inside the cleaning box 1 through a rotating shaft. A first motor 14 is fixed at the position of one sprocket 26 on the outer end of the cleaning box 1, and the output end of the first motor 14 is fixedly connected to the sprocket 26. The outer ring track 24 has upper cleaning components 4 on both sides of its top and lower cleaning components 5 at its bottom. The upper cleaning components 4 include connecting frames 41. The connecting frames 41 are located on both sides of the top of the outer ring track 24, and a first shaft 42 is rotatably mounted inside the connecting frames 41 via bearings. Three rows of cleaning frames 44 are equidistantly mounted on the surface of the first shaft 42, and the cleaning frames 44 are semi-circular frames that wrap around the electrode post surface of the welded part 3. The lower cleaning components 5 include mounting frames 53. The bottom of the outer ring track 24 is symmetrically provided with two sets of mounting brackets 53, and a second shaft 55 is rotatably mounted on the top of the mounting bracket 53. Three brush plates 56 are equidistantly mounted on the surface of the second shaft 55. When using the device, the welded part 3 is intermittently fed in from the inlet and outlet 11. Through the conveying of the track assembly 2, the aluminum cover plate and pole surface of the welded part 3 are cleaned separately by the lower cleaning assembly 5 and the upper cleaning assembly 4. After cleaning, the welded part 3 is sent out from the upper end of the track assembly 2, realizing an efficient cleaning process.

[0034] In this embodiment, the track assembly 2 further includes a limiting plate 25. The limiting plate 25 is fixed to the upper end of the opening of the outer ring track 24, and a delivery plate 21 is fixed to the bottom of the limiting plate 25. A delivery plate 22 is fixed to the lower end of the opening of the outer ring track 24. Chains 27 are meshed on the outer surfaces of the two sprockets 26. A moving notch 28 is provided on the surface of the inner ring track 23. Clamping blocks 29 are fixed at equal intervals on the chain 27, and the welded parts 3 are clamped on the surface of the clamping blocks 29 that protrude from the moving notch 28. After the welded parts 3 are fed in from the delivery plate 22, they enter the gap between the outer ring track 24 and the inner ring track 23. At this time, the clamping blocks 29 move to the back of the welded parts 3 and clamp and fix them, and push them to move. The welded parts 3 are fed in alternately in this way. After the welded parts 3 are cleaned, they are sent out from the top and guided by the limiting plate 25 from the delivery plate. 21 is sent out for easy manual collection. The first motor 14 drives the sprocket 26 to rotate, and the chain 27 drives the clamping block 29 to push multiple sets of welded parts 3, which alternately complete the cleaning. During this process, the gap between the outer ring track 24 and the inner ring track 23 is relatively large, while the basic thickness of the welded parts 3 is relatively small, which can meet the requirement of passing around the semi-circular gap between the outer ring track 24 and the inner ring track 23. The welded parts 3 can be inserted from the feed plate 22 and clamped by the nearest clamping block 29. The clamping block 29 leads the welded parts 3 to go around one circle for cleaning. When it reaches the position of the feed plate 21, the welded parts 3 can be removed manually. The clamping block 29 can be fixed by spring clamp or by electromagnetic clamp, fixing the welded parts 3 and moving around the gap between the outer ring track 24 and the inner ring track 23 to clean different positions of the welded parts 3.

[0035] In this embodiment, a dust collection box 6 is provided in the middle of the inner ring track 23. Two sprockets 26 are rotatably installed at both ends of the dust collection box 6, and a dust suction port is provided on the top of the dust collection box 6. A dust collection device is provided inside the dust collection box 6, and one side of the dust collection box 6 is connected to the outside through an air pipe. The dust collection box 6 isolates the upper and lower ends of the track to prevent debris generated during cleaning at the upper end from falling to the lower end. The debris is collected through the dust suction port and can be cleaned by opening the box door 12.

[0036] In this embodiment, the upper cleaning assembly 4 further includes a toothed ring 45 fixed to the bottom of the cleaning frame 44, and the toothed ring 45 is rotatably mounted on the outer surface of the first shaft 42. The toothed ring 45 and the cleaning frame 44 have corresponding through holes. A rack 43 is slidably inserted into the periphery of the first shaft 42 corresponding to the position of each row of toothed rings 45. The toothed ring 45 and the rack 43 are meshed and connected, and the two ends of the rack 43 slide through the two ends of the connecting frame 41 through bearings. The lower cleaning assembly 5 further includes a bottom frame 51. The bottom of the mounting frame 53 is provided with a bottom frame 51, and spring telescopic rods 52 are fixed at the four corners of the bottom of the dust collection box 6 corresponding to the bottom of the bottom frame 51. The extended end of the spring telescopic rod 52 is fixedly connected to the bottom frame 51. Two vertical plates 46 are symmetrically fixed to the outside of the connecting frame 41, and the bottom of the vertical plates 46 is rotatably connected to a connecting rod 47 through a rotating shaft. The end is rotatably connected to the bottom frame 51 via a rotating shaft. Electric push rods 13 are fixed at equal intervals on the inner wall of the cleaning box 1, corresponding to the position of the vertical plate 46. The extended end of the electric push rod 13 is fixedly connected to the vertical plate 46. When the electric push rod 13 moves the vertical plate 46, the bottom connecting rod 47 of the vertical plate 46 adjusts the position of the bottom frame 51 by rotation. When the vertical plate 46 moves the cleaning frame 44 towards the pole post, the bottom frame 51 also moves upward. When the cleaning frame 44 wraps around the surface of the pole post, the brush plate 56 also presses against the surface of the aluminum cover plate, thus cleaning the aluminum cover plate and pole post surface of the welded part 3. When the vertical plate 46 moves outward, the cleaning frame 44 detaches from the pole post and, under the action of the spring telescopic rod 52, pushes the bottom frame 51 downward, moving the brush plate 56 away from the aluminum cover plate, thus not interfering with the movement of the welded part 3 along the track assembly 2, facilitating replacement for the next batch of processing. Figure 9 and Figure 10 The connection relationships between the connecting frame 41, the vertical plate 46, the connecting rod 47, and the bottom frame 51 can be clearly seen. First, the connecting frame 41 is controlled to move by the electric push rod 13 on the inner wall of the cleaning box 1. The direction of movement is horizontal. During the movement, because the bottom frame 51 is connected to the vertical plate 46 by the connecting rod 47, and the bottom frame 51 is limited by the spring telescopic rods 52 at the top of the four corners, the bottom frame 51 can only move in the vertical direction. Therefore, the horizontal movement of the vertical plate 46 causes the connecting rod 47 to rotate, transferring kinetic energy to the bottom frame 51. Under the guidance and limitation of the spring telescopic rod 52, the bottom frame 51 moves up and down in the vertical direction. This part belongs to the common connecting rod 47 transmission structure. It mainly uses the electric push rod 13 to push the vertical plate 46 to move, thereby realizing the movement of the connecting frame 41 and the cleaning box 44 towards the electrode post. At the same time, the bottom frame 51 at the bottom will move upward to complete the entire cleaning action.

[0037] In this embodiment, a slide rail 54 is fixed on the surface of the bottom frame 51 between the two sets of mounting brackets 53, and a screw device is installed inside the slide rail 54. The two sets of mounting brackets 53 are engaged with the screw device and slide along the slide rail 54. A slide groove 513 is opened on the side of the mounting bracket 53, and a side plate 58 is slidably inserted into the slide groove 513. A transmission belt 57 is installed between the top of the side plate 58 and the mounting bracket 53. One end of the transmission belt 57 is fixedly connected to a pulley and a second shaft 55. A moving groove 514 is opened on the surface of the side plate 58. A limit post 515 is slidably connected in the moving groove 514, and the limit post 515 is in contact with the belt on one side of the transmission belt 57. A return spring is fixed between the moving groove 514 and the limit post 515. 516. A connecting shaft 59 is rotatably mounted on the top of the side plate 58 via a bearing, and the pulley at the other end of the transmission belt 57 is fixed to the connecting shaft 59. A turntable 511 is fixed to one end of the rack 43 near the connecting shaft 59, and an insert 512 is fixed to the surface of the turntable 511. A slot 510 is provided on the connecting shaft 59 corresponding to the position of the insert 512. The insert 512 can be slidably inserted into the slot 510. In this structure, the insert 512 and the slot 510 are laterally slidably inserted. After the insert 512 is inserted into the slot 510, it is limited and can only move laterally, not forward or backward. Therefore, based on this structure, when the electric push rod 13 drives the connecting frame 41 to move horizontally, the insert 512 can be inserted into the slot 510. The turntable 511 is inserted into the connecting shaft 59. At this time, the transmission belt 57 can simultaneously drive the rotation of the first shaft 42 and the second shaft 55, thereby completing the replacement of the cleaning frame 44 and the brush plate 56. To avoid the cleaning frame 44 and the brush plate 56 from having a lot of impurities on them after long-term use, which would affect the cleaning effect, the cleaning frame 44 and the brush plate 56 need to be moved away from the surface of the welded part 3 before replacement. At the same time, driven by the screw device inside the slide rail 54 of the bottom frame 51, the mounting bracket 53 can be moved back and forth, which can also drive the rack 43 to move back and forth and mesh with the toothed ring 45. When the wiping plate moves back and forth, it will wipe the bottom surface of the aluminum cover plate of the welded part 3. When the toothed ring 45 rotates, the cleaning frame 44 rotates to clean the surface of the pole post. The screw device is a common drive device. The mounting bracket 53 is not shown in the figure because it is not positioned in the figure. In this structure, since a slide rail 54 is installed inside the bottom frame 51, and a lead screw device is installed inside the slide rail 54, and the mounting bracket 53 is threaded onto the lead screw device and slides along the slide rail 54, it is only necessary to activate the lead screw device of the slide rail 54 to drive the mounting bracket 53 to move horizontally. This movement range does not need to be too large; it only needs to move horizontally a certain distance to satisfy the meshing of the rack 43 and the toothed ring 45, so that the cleaning frame 44 inside the toothed ring 45 can rotate and clean. Because the side plate 58 connecting the rack 43 and the mounting bracket 53 adopts an up-and-down sliding insertion method, when the mounting bracket 53 moves horizontally, the side plate 58 will also drive the rack 43 to move. Therefore, although the bottom frame 51 is limited by the spring telescopic rod 52, the mounting bracket 53 can still move horizontally.However, this will not affect the movement of mounting bracket 53;

[0038] For the replacement of the cleaning frame 44 and brush plate 56, driven by the transmission belt 57 to rotate simultaneously on the first shaft 42 and the second shaft 55, the second shaft 55 is directly connected to the bottom pulley of the transmission belt 57, while the upper pulley of the transmission belt 57 is connected to the rack 43 on the periphery of the first shaft 42. This can be understood as having an insert ring on the periphery of the first shaft 42 for the rack 43 to slide into. Figure 4 As shown, because the rack 43 rotates together with the transmission belt 57, and because of the sliding engagement between the rack 43 and the first shaft 42, the rotation of the first shaft 42 is transmitted through the rack 43. Here, the rack 43 needs to rotate together with the toothed ring 45 to keep the cleaning frame 44 in place. The cleaning can still be achieved by the meshing of the rack 43 and the toothed ring 45.

[0039] The mounting bracket 53 and the side plate 58 are slidably connected by a groove 513, allowing the bottom frame 51 to move up and down. During this process, the slack of the transmission belt 57 will change. A limiting post 515 is set on the surface of the side plate 58, which is limited by the elastic force of the return spring 516, so that it slides along the moving groove 514 and keeps the belt on one side of the transmission belt 57 in constant contact. In addition, limiting clips are set on both sides of the belt passing over the pulley to maintain the area of ​​the belt wrapped around the pulley. Thus, when the bottom frame 51 moves up and down, the area of ​​the belt wrapped around the pulley can still meet the transmission of the transmission belt 57.

[0040] When using the device, the welding part 3 is intermittently fed in through the inlet / outlet 11. After being fed in through the feed plate 22, the welding part 3 enters the gap between the outer ring track 24 and the inner ring track 23. At this time, the clamping block 29 moves to the back of the welding part 3 to clamp and fix it, and pushes it to move. The welding part 3 is fed in alternately in this way. After the welding part 3 is cleaned, it is sent out from the top and guided by the limiting plate 25 through the discharge plate 21 for easy manual collection. The first motor 14 drives the sprocket 26 to rotate, and the chain 27 carries the welding part 3. The moving clamping block 29 pushes multiple sets of welded parts 3. When the electric push rod 13 drives the vertical plate 46 to move, the bottom connecting rod 47 of the vertical plate 46 adjusts the position of the bottom frame 51 by rotating. When the vertical plate 46 drives the cleaning frame 44 to move towards the pole post, the bottom frame 51 also moves upward. When the cleaning frame 44 wraps around the surface of the pole post, the brush plate 56 also just presses against the surface of the aluminum cover plate, thereby cleaning the surface of the aluminum cover plate and the pole post of the welded parts 3. When the vertical plate 46 moves outward, the cleaning frame 44 will detach from the pole post. The column, under the action of the spring telescopic rod 52, pushes the bottom frame 51 downward, moving the brush plate 56 away from the aluminum cover plate. When the electric push rod 13 drives the connecting frame 41 to move horizontally, the insert block 512 can be inserted into the slot 510, completing the connection between the turntable 511 and the connecting shaft 59. At this time, the transmission belt 57 can simultaneously drive the rotation of the first shaft 42 and the second shaft 55, thereby completing the replacement of the cleaning frame 44 and the brush plate 56, avoiding excessive jointing of the cleaning frame 44 and the brush plate 56 after prolonged use. Impurities affect the cleaning effect. Before replacement, the cleaning frame 44 and brush plate 56 need to be moved away from the surface of the welded part 3. At the same time, driven by the internal screw device of the slide rail 54 of the bottom frame 51, the mounting frame 53 can be moved back and forth, which in turn can also move the rack 43 back and forth, meshing with the toothed ring 45. When the wiping plate moves back and forth, it will wipe the bottom surface of the aluminum cover plate of the welded part 3. When the toothed ring 45 rotates, the cleaning frame 44 rotates to clean the surface of the pole post, realizing an efficient cleaning process.

[0041] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent 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 basic features of the present invention.
