Description

Technical Field

[0001] This invention relates to the technical field of aluminum busbar stamping, specifically to a device and method for thinning aluminum busbars connected in series with power batteries. Background Technology

[0002] The series aluminum busbars used in the power batteries of new energy vehicles are typically manufactured using a continuous stamping device. This device uses aluminum alloy coils as raw materials and achieves fully automated operation through continuous stamping technology: First, the aluminum busbar coils are pre-treated through uncoiling and leveling processes to ensure a flat feeding state; then, the aluminum busbar coils are fed into a multi-station stamping die. Based on continuous feeding of the coils, and with the coordinated connection of each station of the die, multiple processing steps such as blanking, punching, contour forming, and angle bending of the aluminum busbars can be completed sequentially without interrupting the feeding process. During the processing, the aluminum busbar coils maintain a stable state of continuous feeding, ultimately forming conductive connectors for series and parallel connection of battery cells.

[0003] Existing continuous stamping equipment typically uses a spray-type oiling method to lubricate the upper surface of aluminum busbars, which can easily lead to uneven lubrication and oil waste. Since the oiling device is mostly top-spraying, it can only target the upper surface of the aluminum busbar, and the lower surface and edge areas are difficult to be covered with oil. This results in inconsistent lubrication effects on the upper and lower surfaces of the aluminum busbar, which can easily lead to localized oil shortages, increased friction, and consequently, quality problems such as scratches and indentations. To address this issue, a device for thinning aluminum busbars connected in series with power batteries is proposed. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a device and method for thinning aluminum busbars in series for power batteries. This method has the advantage of lubricating both sides of the unstamped aluminum busbars, thus solving the problems of uneven lubrication and oil waste.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a power battery series aluminum bar thinning device, comprising a base, a support plate fixed to the top of the base, a lower mold fixed to the top of the support plate, a support seat fixed to the top of the base, a slide block slidably connected to the inner side wall of the support seat, and an upper mold disposed at the bottom of the slide block. An oiling mechanism is provided on the top of the base, the oiling mechanism comprising a frame, a slider, and a shaft. The frame is fixed to the top of the base; the slider is slidably connected to the frame, and a screw is threaded onto the slider; the shaft is threaded onto the outer side wall of the screw; a sliding rod is fixed to one side of the slider, the sliding rod passing through the shaft; a lubricating roller is rotatably connected to the outer side wall of the shaft; and an oil box is disposed on the inner side wall of the frame near the lower part of the lubricating roller.

[0008] Through the above scheme, the feeding device intermittently outputs aluminum plates between two lubrication rollers. The elastic return of spring three keeps the upper lubrication roller continuously pressing against the upper surface of the aluminum plate, ensuring that the lubricant on the roller is evenly applied to the surface of the aluminum plate. When the lubrication roller is used in the same area for too long, causing impurities to accumulate, the control screw rotates. Because shaft one is threadedly connected to screw one, and the slide rod guides and limits shaft one, shaft one will drive the lubrication roller to move along the axial direction of the slide rod, achieving lateral adjustment of the contact position between the lubrication roller and the aluminum plate, preventing local impurities from affecting the lubrication effect. Simultaneously, the oil box located on the inner wall of the frame below the lubrication roller stores a suitable amount of lubricating oil. When the lubrication roller rotates, its bottom is immersed in the lubricating oil in the oil box, and the rotation evenly distributes the lubricating oil onto the roller surface, thereby applying it to the surface of the aluminum plate, achieving synchronous lubrication of the lower surface of the aluminum plate.

[0009] Preferably, the frame has a sliding groove, the slider 1 slides within the sliding groove, a wedge is slidably connected within the sliding groove, a shaft 2 is rotatably connected to the wedge, and a handwheel is fixed to one end of the shaft 2. A gear 2 is fixed to the outer wall of one end of the screw 1, and a gear 1 that engages with the gear 2 is fixed to the outer wall of the shaft 2.

[0010] The above method involves pressing the handwheel to engage gear two with gear one, and the wedge pressing against slider one, raising the entire lubrication roller to a certain height to prevent it from contacting the aluminum plate. Rotating the handwheel then causes shaft two to rotate gear one, which meshes with gear two, driving screw one to rotate and thus adjusting the lateral position of the lubrication roller. Once adjustment is complete, releasing the handwheel allows the wedge to reset under its own weight or the reset mechanism, disengaging gear one and gear two. Slider one, under gravity or spring force, lowers the lubrication roller, re-engaging it with the aluminum plate for lubrication.

[0011] Preferably, there are two wedges, which are connected by a frame.

[0012] In the above scheme, two wedges are provided, and the two wedges are connected by a frame. The frame connects the two wedges into a whole, so that when the handwheel is pressed, the two wedges can slide synchronously in the groove, thereby applying pressure to the sliders on both sides at the same time. This ensures that the lubrication rollers on both sides can be lifted synchronously, avoiding the aluminum plate from shifting due to uneven force caused by lifting on one side.

[0013] Preferably, the top of the frame is provided with an oil outlet mechanism, which includes a pipe and an oil dripping pipe. The pipe is located inside the frame and one end penetrates the frame. The oil dripping pipe penetrates the frame and is connected to the pipe. A pull rod is slidably connected to the inner wall of the oil dripping pipe. A support block is fixed to one side of the frame. A screw two is provided on the support block. A roller is rotatably connected to the screw two. A slider two is slidably connected to the roller. A connecting rod passes through the slider two. Arc-shaped blocks two are fixed to both ends of the connecting rod. A slider three is fixed to the outer wall of the connecting rod. A spring two is fixed between the slider three and the slider two. A spring one is fixed to the top of the frame. A pressure plate is fixed to the top of the spring one. A connecting rod is fixed to the bottom of the pressure plate. An arc-shaped block one is fixed to the bottom of the connecting rod.

[0014] In this design, the pipeline is used to transport the lubricating medium. One end of the pipeline passes through the frame to connect with an external feeding device. The dripping pipe is connected to the pipeline, allowing the lubricating medium inside the pipeline to drip onto the lubrication roller. When oil is needed, the pull rod can be pulled to slide against the inner wall of the dripping pipe, thus opening the oil outlet and allowing the lubricating medium to drip out. When oil is not needed, the pull rod can be released, and the outlet can be closed by its own weight or the action of a spring.

[0015] Preferably, a sleeve is rotatably connected to the inner wall of the support block, and the sleeve is threadedly connected to the screw rod. A gear is rotatably connected to one side of the frame, and the gear meshes with the sleeve. A shaft is rotatably connected to the frame, and a flexible strip is fixed to the outer wall of the shaft. The shaft is splinedly connected to the shaft.

[0016] With the above scheme, shaft three can rotate synchronously under the drive of shaft two, thereby causing the flexible strip to rotate as well. While the lubricating roller moves, the flexible strip performs friction cleaning on the lubricating roller.

[0017] Preferably, the top of the base is provided with an oil pumping mechanism, which includes a pressure block and an oil tank. The pressure block is fixed to the outer side wall of the slide. The oil tank is fixed to one side of the frame, and a pressing valve is provided on the top of the oil tank. The pressing valve is provided with an oil outlet.

[0018] With the above scheme, the pressure block can move synchronously with the slide. When the slide moves the pressure block closer to the oil drum, the pressure block can squeeze the press valve, causing the press valve to open, and the lubricating medium in the oil drum will be discharged through the oil outlet. When the slide moves the pressure block away from the oil drum, the squeezing force of the pressure block on the press valve disappears, and the press valve closes under its own elasticity, stopping the oil discharge.

[0019] A method of using a power battery series-connected aluminum busbar thin-walled device includes:

[0020] The aluminum plate is transferred between two lubrication rollers, where a lubricating film forms on its surface.

[0021] The aluminum sheet is continuously fed between the lower and upper molds, and is then pressed down by the slide block to form a thinner sheet.

[0022] When it is necessary to adjust the lateral position of the lubrication roller, press the handwheel to make the wedge block squeeze the slider one, raising the height of one of the lubrication rollers. Rotate the handwheel, and the shaft two will mesh with the two gears two respectively, causing the two screws one to rotate. The screws one are threadedly connected to the shaft one. The sliding rod restricts the movement of the lubrication roller laterally.

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, the present invention provides a thin aluminum stacking device for power batteries in series, which has the following beneficial effects:

[0025] 1. This power battery series aluminum plate thinning device incorporates an oiling mechanism during aluminum plate transport. Two upper and lower lubrication rollers simultaneously lubricate the upper and lower surfaces of the aluminum plate, effectively solving the problem of insufficient lubrication in traditional spray-type oiling, which only lubricates the upper, lower, and edge areas. The lubricating oil in the oil box continuously wets the lower lubrication roller, while the upper lubrication roller remains moist due to lubricating oil dripped from the oil outlet mechanism. As the aluminum plate passes between the two lubrication rollers, the upper lubrication roller adheres tightly to the upper surface of the aluminum plate under the elastic action of spring three, while the lower lubrication roller adheres to the lower surface. With the transport of the aluminum plate, the two lubrication rollers rotate synchronously, evenly spreading the lubricating oil on both sides of the aluminum plate to form a complete and uniform lubricating film, avoiding quality defects such as scratches and indentations caused by uneven lubrication.

[0026] 2. This power battery-connected aluminum strip thinning device allows for localized impurity accumulation or wear on the lubrication roller after prolonged use. Simply press the handwheel to engage gear one and gear two, simultaneously causing the wedge to press the slider one, raising the height of the lubrication roller. Rotating the handwheel drives the screw one to rotate. Guided and limited by the slide rod, the shaft one moves the lubrication roller laterally, switching the contact position. This effectively avoids the problem of localized wear on the lubrication roller affecting the overall lubrication effect, extending the service life of the lubrication roller.

[0027] 3. This power battery is connected in series with the aluminum strip thinning equipment. By incorporating an oil pump mechanism, which uses a sliding block to press the pressure valve on the oil tank, oil is dispensed only during the thinning operation, avoiding the oil waste caused by continuous oil supply in traditional spray-type oiling. The dripping pipe in the oil dispensing mechanism, in conjunction with a pull rod, controls the oil output, and the dripping pipe's outlet position is directly opposite the lubrication roller, ensuring that the lubricating oil drips directly onto the roller surface. Furthermore, a flexible strip rotates with the shaft, rubbing and cleaning the surface of the lubrication roller as it moves laterally, preventing impurities from adhering and affecting the uniform application of lubricating oil.

[0028] 4. This power battery series aluminum plate thinning device uses a slidingly connected arc-shaped block two on the frame. When the aluminum plate is being transported, it will squeeze a corresponding number of arc-shaped blocks two, causing them to move away from the aluminum plate, which in turn drives arc-shaped block one to move upward. While the connecting rod drives the pressure plate upward, it changes the height of the pull rod inside the oil dripping pipe, thereby controlling the oil discharge state of the corresponding oil dripping pipe according to the width of the aluminum plate.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] When using spray-type oiling to lubricate the upper surface of aluminum busbars, problems such as uneven lubrication, oil waste, and subsequent cleaning difficulties are common. Because oiling devices often use top spraying, they can only target the upper surface of the aluminum busbar, leaving the lower surface and edges uncovered. This results in inconsistent lubrication between the upper and lower surfaces, easily leading to localized oil shortages, increased friction, and consequently, scratches, indentations, and other quality issues. Furthermore, the sprayed oil is prone to uneven distribution, with oil accumulation in some areas and insufficient oil film in others. This not only wastes oil but also causes sludge and aluminum shavings to adhere to the surface of the oiling roller, increasing cleaning difficulty. This application proposes a device for thinning series-connected aluminum busbars for power batteries.

[0045] As attached Figure 1-6 As shown, the power battery series aluminum block thinning equipment includes a base 110, a support plate 120, a lower mold 130, an upper mold 140, a slide 150, and a support base 160. The support plate 120 is fixed to the top of the base 110, the lower mold 130 is fixed to the top of the support plate 120, the support base 160 is fixed to the top of the base 110, the slide 150 is slidably connected to the support base 160, and the upper mold 140 is fixed to the bottom of the slide 150.

[0046] Specifically, during continuous stamping operations, the aluminum sheet is first smoothly conveyed to the mold closing station between the lower mold 130 and the upper mold 140 via continuous feeding. The upper mold 140 is driven by the drive slide 150 to perform periodic, continuous reciprocating lifting and lowering movements, cooperating with the lower mold 130 to complete the synchronous stamping and forming of the aluminum sheet. The process waste generated during stamping is orderly guided into the inner cavity area of ​​the lower support plate 120 through a pre-set discharge channel on the lower mold 130, achieving centralized discharge of waste and preventing waste accumulation from interfering with the continuous stamping process. Simultaneously, during the mold closing stage where the upper mold 140 descends with the slide 150 and gradually contacts the lower mold 130, the shock-absorbing components arranged at the four corners of the mold work synchronously. Through elastic buffering and damping energy absorption, they effectively weaken the instantaneous impact load and rigid force of the upper mold 140 during its descent, reducing the impact of stamping vibration on the forming accuracy of the sheet and maintaining the stability of the mold closing process. The above-mentioned stamping upsetting process is existing technology and will not be elaborated here.

[0047] In this embodiment, an oiling mechanism is added to the aluminum plate before stamping; the oiling mechanism applies oil to both sides of the output aluminum plate, and a uniform lubricating film is formed on the surface of the aluminum plate, which effectively reduces the friction between the aluminum plate and the mold, and reduces the occurrence of scratches and other damage during stamping.

[0048] Specifically, the oiling mechanism includes a frame 210, a slider 220, a screw 230, a slide bar 240, a shaft 250, a lubrication roller 260, and an oil box 270. The frame 210 is fixed to the top edge of the base 110. Two sliders 220 are slidably connected to the inner wall of the frame 210. A screw 230 is rotatably connected to the two sliders 220. Another screw 230 is rotatably connected to the inner wall of the frame 210. A spring 3 connects the sliders 220 and the frame 210. A shaft 250 is provided on the outer wall of the screw 230. A lubrication roller 260 is provided on the outer wall of the shaft 250. An oil box 270 is fixed to the inner wall of the frame 210 near the lower part of the lubrication roller 260.

[0049] More specifically, the slide bar 240 is fixed between two sliders 220 and passes through the shaft 250. The screw 230 is threadedly connected to the shaft 250, and the shaft 250 is rotatably connected to the lubrication roller 260 through a bearing. By rotating the screw 230, the screw 230 rotates on the slider 220 and is threadedly connected to the shaft 250. At this time, due to the restriction of the slide bar 240, the shaft 250 moves linearly on the slide bar 240, thereby driving the lubrication roller 260 to move. This changes the oiling position of the lubrication roller 260, preventing the lubrication roller 260 from being used in one area for a long time, which would lead to the accumulation of impurities and overload, affecting the surface of the aluminum busbar.

[0050] As attached Figure 3-6As shown, to avoid stopping the machine when adjusting the lateral position of the two lubrication rollers 260, a transmission mechanism 400 is installed on the frame 210. By controlling the position of the transmission mechanism 400, the two screws 230 can be connected and their distance can be adjusted, thereby reducing the friction on the aluminum plate surface when the two lubrication rollers 260 move laterally.

[0051] In this embodiment, the transmission mechanism 400 includes a second shaft 410, a handwheel 420, a first gear 430, a wedge 450, and a second gear 460. The wedge 450 is slidably connected to the inner side wall of the frame 210, and the second shaft 410 is rotatably connected to the wedge 450. The first gear 430 is fixed to the outer side wall of the second shaft 410, and the handwheel 420 is fixed to one end of the second shaft 410. The second gear 460, which is matched with the first gear 430, is fixed to the outer side wall of the first screw 230. The wedge 450 has an inclined surface.

[0052] Specifically, when it is necessary to adjust the lateral position of the two lubrication rollers 260, the handwheel 420 can be pressed first, causing the wedge 450 to press against the slider 220, which moves the slider 220 upward along the inclined plane, thereby pushing the lubrication roller 260 upward and away from the other lubrication roller 260 until gear 430 engages with gear 460. Then, the handwheel 420 is rotated, and through the meshing transmission of gear 430 and gear 460, the two screws 230 are driven to rotate synchronously, thereby controlling the movement of the two shafts 250. This achieves the goal of adjusting both shafts 250 by operating only one end, effectively reducing the difficulty of operation.

[0053] In this embodiment, two wedges 450 are provided on the frame 210 and are connected by a frame 440. When one handwheel 420 moves laterally, the other handwheel 420 will be driven to move by the connection of the frame 440, so that both ends of the screw 230 are raised at the same time, reducing the contact between the lubrication roller 260 and the aluminum plate.

[0054] As attached Figure 3-6 As shown, an oil outlet mechanism 300 is added to the frame 210 to control the dripping of lubricating fluid onto the lubrication roller 260. The oil outlet mechanism 300 can automatically adjust the dripping width according to the width of the aluminum plate, thereby avoiding the need for operators to adjust it individually.

[0055] In this embodiment, the oil outlet mechanism 300 includes an oil dripping pipe 320, a pull rod 330, a pressure plate 610, a connecting rod 620, and an arc-shaped block 630. Multiple oil dripping pipes 320 are provided through the top of the frame 210. A transverse pipe 310 is provided inside the top of the frame 210. The pipe 310 is transversely connected to and communicates with the multiple oil dripping pipes 320. A pull rod 330 is slidably connected inside the oil dripping pipe 320. A spring is fixed between the pull rod 330 and the oil dripping pipe 320. A valve body is provided at the bottom of the pull rod 330 to block the outlet of the oil dripping pipe 320. The spring and the valve body are not shown in the attached drawings. The principle is similar to the one-way valve in the prior art, and will not be described in detail here.

[0056] Specifically, by controlling the height of the lever 330, the position of the valve body within the drip pipe 320 is controlled, allowing the lubricating oil introduced into the pipe 310 to be discharged through the bottom of the lever 330.

[0057] In this embodiment, multiple springs 640 are fixed to the top of the frame 210, and a pressure plate 610 is fixed to the top of the springs 640. The pressure plate 610 is engaged with the bottom of the pull rod 330. A connecting rod 620 is fixed to the bottom of the pressure plate 610, and an arc-shaped block 630 is fixed to the bottom of the connecting rod 620. Two support blocks 710 are fixed to one side of the frame 210. A screw 730 is rotatably connected between the two support blocks 710. A roller 740 is provided on the outer wall of the screw 730. Multiple connecting rods 790 are slidably connected to the roller 740. Arc-shaped blocks 750 are fixed to both ends of the connecting rods 790.

[0058] Specifically, during the continuous output of the aluminum plate, it will rub against the second arc block 750, thereby driving the roller 740 to rotate. During this process, the pressure of the aluminum plate will cause the second arc block 750 to move away from the aluminum plate. The second arc block 750 will then press the first arc block 630. The first arc block 630 will then drive the connecting rod 620 and the pressure plate 610 to move upward, thereby driving the pull rod 330 to lift upward once. When the aluminum plate is output, the corresponding area of ​​the drip pipe 320 drips out lubricating fluid.

[0059] As attached Figure 3-6 As shown, after the two lubrication rollers 260 move to one side, they need to be cleaned. Therefore, a shaft three is rotatably connected to the frame 210. The shaft three is equipped with a flexible strip, which can be made of rubber. The shaft three and the shaft two 410 are connected by a spline. Therefore, when the shaft two 410 is rotated, the shaft three will also drive the flexible strip to rotate, so that the lubrication rollers 260 can be cleaned while moving laterally, thereby reducing the difficulty of cleaning.

[0060] In this embodiment, to further improve the cleaning of the two lubrication rollers 260, a sleeve 720 is rotatably connected to the inner wall of the support block 710. The sleeve 720 is threadedly connected to the screw 730, and the screw 730 is connected to the roller body 740 through a bearing. A gear 470 is rotatably connected to one side of the frame 210, and the gear 470 meshes with the sleeve 720. After the screw 230 is raised, it can mesh with the gear 470. Therefore, by controlling the rotation of one shaft 410, the lubrication rollers 260 are moved laterally, and at the same time, multiple arc-shaped blocks 750 are moved laterally accordingly. (See attached...) Figure 6 As shown, a baffle is fixed on one side of the support block 710. When the arc-shaped block 750 moves, the arc-shaped block 750 will be squeezed by the baffle, causing the arc-shaped block 750 to move away from the baffle and squeeze the lubrication roller 260, squeezing out the lubricating liquid containing impurities in the lubrication roller 260, and further cleaning the lubrication roller 260.

[0061] As attached Figure 1-6 As shown, a pumping mechanism 500 is provided on the top of the base 110. The pumping mechanism 500 includes a pressure block 510, an oil tank 520, and an oil outlet head 530. The pressure block 510 is fixed at the bottom of the slide 150, and the oil tank 520 is fixed on one side of the frame 210. The oil tank 520 is connected to the oil box 270 through a pipe. A press valve is provided on the top of the oil tank 520, and an oil outlet head 530 is provided at the outlet end of the press valve. The outlet end of the oil outlet head 530 is connected to the pipe 310. During the downward pressing process of the slide 150, the oil outlet head 530 is impacted. The oil outlet head 530 continuously presses the press valve downward, thereby pumping the lubricating fluid in the oil tank 520 into the pipe 310. The press valve is not shown in the attached figure and belongs to the prior art, so it will not be described in detail here.

[0062] As attached Figure 1-6 As shown in the accompanying drawings, the teeth of the multiple gears in this application are not shown.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
