Description

Technical Field

[0001] The present invention relates to the technical field of processing and conveying of aluminum shells for new energy vehicle batteries, and specifically provides a processing and conveying device for aluminum shells of new energy vehicle batteries. Background Art

[0002] As a core outer packaging structural part of power batteries, the aluminum shell of new energy vehicle batteries is usually made of aluminum alloy material. To meet the requirements of electrical insulation, explosion-proof heat insulation, and mechanical protection, etc., insulating films are generally pasted and coated on the peripheral side and bottom of the battery aluminum shell.

[0003] In the prior art, when pasting and coating the insulating film on the battery aluminum shell, it is usually through a multi-axis adjustment conveying device to drive the battery aluminum shell to cooperate with multi-station step-by-step processing, so as to sequentially complete processes such as precise coating of the insulating film, edge trimming, side wall fitting, and waste material treatment, and finally convey and discharge the coated battery aluminum shell to achieve the complete fitting of the insulating film on the surface of the aluminum shell.

[0004] However, the traditional method of coating the insulating film on the battery aluminum shell through complex conveying adjustment and multi-stations has the following problems: 1. In the prior art, since the multi-axis adjustment conveying device needs to independently adjust the posture of the battery aluminum shell for each station to adapt to different processes such as coating, trimming, and fitting, the multi-axis adjustment conveying device needs to frequently perform actions such as lifting and rotating to match the operation requirements of each link, which not only leads to an extension of the overall conveying stroke of the battery aluminum shell and an increase in the number of mechanical action switches, but also the requirement for the fitting accuracy of the insulating film will increase the time and number of times of calibration and positioning of the battery aluminum shell, further increasing the time-consuming of the entire process and the complexity of the operation, thus affecting the overall conveying efficiency of the battery aluminum shell; 2. In the prior art, since processes such as coating, trimming, and fitting need to be independently set up stations, it not only results in a large overall floor area of the equipment and a high space cost for production and processing, but also the connection between each station needs to realize the step-by-step conveying and turnover of the battery aluminum shell by extending the conveying path, thus further increasing the ineffective conveying stroke of the battery aluminum shell and reducing the conveying efficiency. At the same time, the superimposed configuration of the corresponding functional components for multiple stations not only raises the overall hardware cost of the equipment, but also its complex mechanical cooperation structure increases the difficulty of daily maintenance and the cost of long-term operation and maintenance.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By the cooperation of the conveying mechanism and the guiding mechanism, the present invention can not only realize the wrapping of the insulating film on the circumferential side of the battery aluminum shell through the simple unidirectional rotation adjustment of the battery aluminum shell, but also realize the conveying and blanking of the formed aluminum shell through the unidirectional lifting and pushing of a short stroke, avoiding the multi-station conversion and repeated calibration and positioning of the battery aluminum shell, reducing both the switching frequency of mechanical actions and the redundant stroke during the aluminum shell conveying process, and reducing the positioning load of the equipment through the linearization of the aluminum shell movement trajectory. Thus, while ensuring the wrapping accuracy, the conveying rhythm is significantly accelerated, and the overall conveying efficiency and process stability of the aluminum shell are improved.

[0019] 2. By the cooperation of the guiding mechanism and the smoothing mechanism, the present invention can concentrate the wrapping process of the insulating film on the circumferential side and the bottom of the battery aluminum shell in the same processing area, eliminating the redundant space occupation of the multi-station independent layout, significantly reducing the overall floor area and production space cost of the equipment, and enabling the aluminum shell to avoid long-distance transfer between multiple stations, greatly reducing the ineffective stroke and conveying time. At the same time, the process integration reduces the overall number of independent functional components and simplifies the cooperation relationship of the overall mechanical structure, reducing both the equipment hardware input cost and the complexity of daily maintenance and long-term operation and maintenance costs.

[0033] Please refer to Figure 1 and Figure 2, the blanking conveying part 21 includes a first cylinder 211 fixedly arranged inside the left U-shaped bracket through a fixing seat. A U-shaped push plate 212 that moves left and right and has an opening facing right is fixedly arranged at the telescopic end of the first cylinder 211. The right end of the U-shaped push plate 212 is a bevel that is symmetric front and back.

[0034] Please refer to Figure 1 and Figure 2 , the lifting conveying part 22 includes a receiving groove opened on the upper surface of the processing conveying table 1. A second cylinder 221 is fixedly arranged on the lower side of the processing conveying table 1. A lifting table 222 that moves up and down and is inserted and matched with the receiving groove is fixedly arranged at the telescopic end of the second cylinder 221. A plurality of first guide rods that are fixedly arranged evenly on the lower side of the lifting table 222 and are slidably connected to the processing conveying table 1 are provided. Positioning columns 223 are symmetrically and fixedly arranged on the upper surface of the lifting table 222 along the front side edge direction and along the left side edge direction.

[0035] Drive the lifting table 222 in the receiving groove to move upward to the highest position through the second cylinder 221, and then horizontally place the bottom of the battery aluminum shell facing right on the lifting table 222 through the feeding device, and make the front side and the left side of the battery aluminum shell stably fit on the surfaces of the corresponding positioning columns 223. At this time, the left end of the battery aluminum shell is flush with the left end of the insulating film, so as to complete the feeding of the battery aluminum shell.

[0036] When it is necessary to unload the battery aluminum shell with the peripheral and bottom insulating films wrapped on the lifting table 222, first drive the lifting table 222 and the battery aluminum shell wrapped and formed on the lifting table 222 to move downward and reset into the receiving groove through the second cylinder 221, and then drive the U-shaped push plate 212 to move rightward through the first cylinder 211 until the inner side of the U-shaped push plate 212 fits the outer side of the battery aluminum shell. Then continue to drive the U-shaped push plate 212 and the battery aluminum shell to move rightward through the first cylinder 211 until the battery aluminum shell passes through the inner side of the right U-shaped bracket to complete the blanking. The bevel at the right end of the U-shaped push plate 212 can guide and correct the slightly deviated battery aluminum shell to ensure that the battery aluminum shell can be stably framed into the inner side of the U-shaped push plate 212.

[0037] Please refer to Figure 1 , the guiding mechanism 3 includes a fixing table 31 fixedly arranged on the upper side of the U-shaped bracket. A rotary guiding part 32 for clamping and rotating and adjusting the aluminum shell is arranged on the fixing table 31. A moving conveying part 33 is jointly arranged on the upper side of the fixing table 31 symmetrically left and right. An adsorption cutting part 34 for adsorbing, positioning and cutting the insulating film is arranged on the moving conveying part 33. A fitting and flattening part 35 for pressing and leveling the insulating film on the surface of the aluminum shell in cooperation with the moving conveying part 33 is arranged on the adsorption cutting part 34.

[0038] Please refer to Figure 1 and Figure 2, the rotation guiding part 32 includes a first motor 321 fixedly arranged on the opposite sides of the left and right symmetric fixed platforms 31. A driving end of the first motor 321 is fixedly provided with a return-shaped frame. A third cylinder 322 is installed in the return-shaped frame. A telescopic end of the third cylinder 322 is fixedly provided with a clamping plate 323 that moves left and right.

[0039] When the battery aluminum shell is loaded, first, the third cylinder 322 drives the left and right symmetric clamping plates 323 to move synchronously and relatively until the clamping plates 323 stably clamp and fix the battery aluminum shell on the lifting platform 222. Then, the second cylinder 221 drives the lifting platform 222 to move downward by a certain distance. At this time, the first motor 321 can drive the return-shaped frame and the third cylinder 322 to rotate directionally, and the third cylinder 322 drives the clamped battery aluminum shell to rotate directionally synchronously through the clamping plate 323.

[0040] Please refer to Figure 1 and Figure 3 , the moving and conveying part 33 includes a first guide rail 331 fixedly arranged on the upper side of the fixed platform 31 through a support rod. An electric slider 332 that moves back and forth is slidably arranged on the first guide rail 331. A U-shaped moving platform is fixedly arranged between the left and right symmetric electric sliders 332. A fourth cylinder 333 is fixedly arranged on the upper side of the horizontal section of the U-shaped moving platform.

[0041] Please refer to Figure 3 and Figure 4 , the adsorption and cutting part 34 includes a first fixing plate that moves up and down and is fixedly arranged at the telescopic end of the fourth cylinder 333. Second guide rods that are slidably connected to the U-shaped moving platform are symmetrically and fixedly arranged on the upper side of the first fixing plate. Two groups of electric suction cups 341 are symmetrically installed on the lower side of the first fixing plate in the front and back. Each group consists of a plurality of electric suction cups 341 evenly distributed left and right. A fifth cylinder 342 is fixedly arranged on the upper side of the first fixing plate. A connecting plate 1 that moves up and down and is located between the two groups of electric suction cups 341 is fixedly arranged at the telescopic end of the fifth cylinder 342. Third guide rods that are slidably connected to the first fixing plate are symmetrically and fixedly arranged on the upper side of the connecting plate 1. A blade 343 that extends left and right is fixedly arranged on the lower side of the connecting plate 1.

[0042] The left and right symmetric electric sliders 332 can drive the U-shaped moving platform and the fourth cylinder 333 to move back and forth along the first guide rail 331 for adjustment. The fourth cylinder 333 can drive the first fixing plate to move synchronously. And the fourth cylinder 333 can drive the first fixing plate to move up and down for adjustment. Among them, the electric suction cups 341 on the lower side of the first fixing plate can stably position and adsorb the insulating film. The fifth cylinder 342 on the first fixing plate can drive the connecting plate 1 and the blade 343 to move up and down to cut the insulating film.

[0043] Please refer to Figure 1 , Figure 3 and Figure 5, the fitting and flattening part 35 includes fixing plates two symmetrically fixed on the front and back of the fixing plate one. A cylinder six 351 is fixedly arranged on the upper side of the fixing plate two. A connecting plate two moving up and down is fixedly arranged at the telescopic end of the cylinder six 351. Guide rods four slidably connected to the fixing plate two are symmetrically fixed on the left and right of the upper side of the connecting plate two. Elastic sliding rods one 352 are symmetrically arranged on the left and right of the lower side of the connecting plate two through inclined supports one. A flattening roller one 353 is jointly hinged between the left and right symmetric elastic sliding rods one 352.

[0044] The fixing plate one can drive the fixing plate two to move synchronously for front-back and up-down adjustment. The cylinder six 351 on the fixing plate two can drive the elastic sliding rod one 352 and the flattening roller one 353 to move up and down through the connecting plate two.

[0045] When the insulating film is to be wrapped and fitted around the circumference of the battery aluminum shell, first, the electric slider one 332 and the cylinder four 333 cooperate to drive the fixing plate one and the electric suction cup 341 to move backward to the rearmost side and downward to the lowest position at the same time. A part of the active section of the coiled insulating film adsorbed and positioned on the lower side is driven by a group of electric suction cups 341 on the front side of the fixing plate one to fit on the rear end of the upper surface of the battery aluminum shell. Then, the adsorption force of the front group of electric suction cups 341 is disconnected, and at the same time, the corresponding elastic sliding rod one 352 and the flattening roller one 353 are driven by the front cylinder six 351 to move downward until, under the action of the elastic sliding rod one 352, the rear end of the active section of the insulating film is stably flattened and fitted on the rear surface of the battery aluminum shell (as Figure 8 shown).

[0046] Then, the corresponding flattening roller one 353 is driven by the front cylinder six 351 to move upward and reset a specific distance. Then, the electric slider one 332 and the cylinder four 333 cooperate to drive the fixing plate one and the fixing plate two to move forward synchronously along the upper surface of the battery aluminum shell by a specific distance, so that the front flattening roller one 353 stably flattens and fits the insulating film on the upper surface of the battery aluminum shell (as Figure 8 shown).

[0047] Then, the electric slider one 332 and the cylinder four 333 cooperate to drive the fixing plate one and the fixing plate two to move out of the way, and the clamping plate 323 and the battery aluminum shell are driven by the motor one 321 to rotate ninety degrees directionally (as shown by the middle arrow in Figure 8 ). Then, the electric slider one 332 and the cylinder four 333 cooperate to drive the fixing plate two and the front flattening roller one 353 to move forward along the upper surface of the battery aluminum shell at this time until the insulating film is stably flattened and fitted on the upper surface of the battery aluminum shell at this time (as Figure 8 shown).

[0048] Next, the motor 321 drives the aluminum battery case to rotate in the same direction by another 90 degrees, and the electric slider 332 and the cylinder 333 cooperate to drive the front flattening roller 353 to move forward along the upper surface of the aluminum battery case at this time to the front end of the guide rail 331, so as to stably flatten and attach the insulating film to the upper surface of the aluminum battery case at this time, and align the rear flattening roller 353 with the front surface of the aluminum battery case (as Figure 8 shown).

[0049] At this time, the front and rear groups of electric suction cups 341 stably adsorb and position the movable section of the insulating film, and the cylinder 342 drives the blade 343 to move downward to cut off the insulating film covering the aluminum battery case from the rolled insulating film. Then, the adsorption force of the rear group of electric suction cups 341 is disconnected, and at the same time, the cylinder 351 at the rear drives the corresponding flattening roller 353 to move downward until the disconnected insulating film is stably flattened and attached to the front surface of the aluminum battery case at this time (as Figure 8 shown), thus completing the fitting and covering of the insulating film around the aluminum battery case.

[0050] Finally, the lifting platform 222 is moved upward again to stably support the aluminum battery case, and the electric slider 332 and the cylinder 333 cooperate to drive the front electric suction cup 341 that adsorbs and positions the movable end of the rolled insulating film to move and adjust to the highest position at the rear end, so as to facilitate the fitting and covering of the insulating film around the next aluminum battery case.

[0051] Please refer to Figure 1 , the smoothing mechanism 4 includes a positioning and conveying part 41 arranged on the left fixed platform 31 and used for moving and positioning the insulating film on the right side of the aluminum case. A pressing and smoothing part 42 and an alternating pressing part 43 for pressing and smoothing the front and rear ends and the upper and lower sides of the insulating film on the right side of the aluminum case are arranged on the positioning and conveying part 41.

[0052] Please refer to Figure 1 and Figure 6 , the positioning and conveying part 41 includes guide rails 411 symmetrically installed on the right fixed platform 31 front and rear. Electric sliders 412 that move left and right are slidably arranged on the guide rails 411. L-shaped connecting platforms are fixedly arranged on the opposite sides of the front and rear symmetric electric sliders 412. A loop-shaped moving frame 413 is fixedly arranged on the left side of the front and rear symmetric L-shaped connecting platforms together.

[0053] Please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7, the pressing and smoothing part 42 includes cylinders seven 421 symmetrically and fixedly arranged on the outer side of the loop-shaped moving frame 413 from front to back. The telescopic end of the cylinder seven 421 is fixedly provided with a U-shaped frame that moves back and forth inside the loop-shaped moving frame 413. A plurality of guide rods five that are slidably connected to the loop-shaped moving frame 413 are evenly and fixedly arranged on one side of the U-shaped frame close to the corresponding cylinder seven 421. Linear grooves that extend vertically and penetrate from front to back are symmetrically opened on the left and right sides of the vertical section of the U-shaped frame. A motor two 422 is fixedly arranged on the upper side of the U-shaped frame. The driving end of the motor two 422 is fixedly provided with a bidirectional screw rod 423 that is rotatably connected between the horizontal sections of the U-shaped frame. The bidirectional screw rod 423 is symmetrically threadedly connected with driven blocks 424 up and down. On one side of the driven block 424 close to the corresponding cylinder seven 421, sliding shafts that are slidably connected to the corresponding linear grooves are symmetrically and fixedly arranged on the left and right sides. On the side of the driven block 424 far from the corresponding cylinder seven 421, a pressing block 425 is fixedly arranged. The opposite ends of the pressing blocks 425 that are symmetrically arranged from front to back are arc-shaped surfaces.

[0054] When it is necessary to press and smooth the front and rear ends of the loop-shaped insulating film protruding from the right side of the battery aluminum shell, first drive the L-shaped connecting platform and the loop-shaped moving frame 413 to move to the leftmost end along the guide rail two 411 through the electric slider two 412, so that the pressing block 425 is aligned with the right surface of the battery aluminum shell (as Figure 9 shown in the upper side), then drive the symmetrically arranged U-shaped frames and the pressing blocks 425 on the left and right to move relatively synchronously by a specific distance through the cylinder seven 421. The corresponding ends of the protruding loop-shaped insulating film are gradually pressed and attached to the right surface of the battery aluminum shell by the symmetrically arranged pressing blocks 425 up and down. The arc-shaped surfaces on the pressing blocks 425 can ensure that the insulating film is stably attached during the pressing process and no wrinkles will appear. Then drive the bidirectional screw rod 423 to rotate directionally through the motor two 422. The bidirectional screw rod 423 then drives the symmetrically arranged driven blocks 424 and the pressing blocks 425 to move away from each other synchronously through screw transmission. The pressing blocks 425 then smooth the front and rear ends of the loop-shaped insulating film to the upper and lower sides synchronously, so as to press the upper and lower sides of the loop-shaped insulating film into a trapezoid that is convenient for pressing and folding (as Figure 9 shown in the middle). Finally, drive the pressing block 425 to move back to the initial position through the motor two 422 and the cylinder seven 421. When the right surface of the battery aluminum shell is stressed, the paired positioning columns 223 on the left side can stably support the left side of the battery aluminum shell.

[0055] Please refer to Figure 1 、 Figure 2 and Figure 6, the alternating pressing part 43 includes air cylinders eight 431 symmetrically and fixedly arranged on the outer side of the rectangular moving frame 413 in the up-and-down direction. A telescopic end of the air cylinder eight 431 is fixedly provided with a connecting plate three that is located inside the rectangular moving frame 413 and moves up and down. On one side of the connecting plate three close to the corresponding air cylinder eight 431, guide rods six that are slidably connected to the rectangular moving frame 413 are symmetrically and fixedly arranged in the front and back directions. On one side of the connecting plate three away from the corresponding air cylinder eight 431, spring rods two 432 are symmetrically and elastically slidably arranged through inclined supports two in the front and back directions. A flattening roller two 433 is jointly hinged between the spring rods two 432 that are symmetrically arranged in the front and back directions.

[0056] When it is necessary to complete the covering of the insulating film on the peripheral side and bottom of the battery aluminum shell, driven by the synchronous movement of the rectangular moving frame 413, the flattening roller two 433 also aligns with the right surface of the battery aluminum shell. First, the air cylinder eight 431 on the upper side drives the spring rod two 432 and the flattening roller two 433 on the lower side of the corresponding connecting plate three to move downward. Thus, under the action of the spring rod two 432, the upper trapezoidal insulating film is flattened and attached to the right surface of the battery aluminum shell through the flattening roller two 433. Then, the upper flattening roller two 433 is moved back to the initial position, and the corresponding flattening roller two 433 is driven by the air cylinder eight 431 on the lower side to move upward to flatten and attach the lower trapezoidal insulating film to the right surface of the battery aluminum shell (as shown in the lower side below), so as to complete the covering of the insulating film on the peripheral side and bottom of the battery aluminum shell. Finally, the covered battery aluminum shell can be stably unloaded through the cooperation of the lifting platform 222 and the U-shaped pushing plate 212. Figure 9 The above operation method can not only realize the covering and unloading of the insulating film of the battery aluminum shell through simple rotation adjustment and simple short-stroke conveying, but also realize the centralized processing of the covering of the insulating film of the battery aluminum shell in a unified processing area. Thus, it not only reduces the switching frequency of mechanical actions and redundant strokes during the conveying process of the aluminum shell, but also reduces the positioning load of the equipment by linearizing the movement track of the aluminum shell, improves the overall conveying efficiency and process stability of the aluminum shell, significantly reduces the ineffective stroke and conveying time consumption at the same time, and reduces the costs such as the overall space occupation and hardware investment of the equipment.
