Description

Technical Field

[0001] This utility model relates to the field of new energy battery shell molding and processing, and in particular to a new energy battery square shell edge cutting mechanism with an oil scraping and edge cutting device. Background Technology

[0002] In battery casing production lines, due to process requirements, the surface of the casing needs to be coated with stretching oil during the prismatic forming process of new energy battery casings. This facilitates better stretching and forming, reduces friction, and dissipates heat generated during stretching to meet customer requirements. However, this also results in high cost of stretching oil, significant oil loss during transportation, and increased difficulty, time, and cost of subsequent cleaning processes, necessitating oil filtration before cleaning. Furthermore, significant oil loss occurs during the casing's transportation before reaching the cleaning stage. Therefore, the amount of oil filtered out during the cleaning process is considerably less.

[0003] Therefore, after applying oil to the battery casing, it is usually necessary to use an oil scraping device to scrape the oil off the surface of the battery casing so that the oil can be reused, reducing oil costs and production processing costs, and minimizing oil loss.

[0004] For example, a cleaning, oil-scraping, and edge-cutting device for aluminum shell production of new energy batteries (publication announcement number CN221017549U) disclosed on the China Patent Network uses a multi-cylinder driven mechanism as a power source to push the scraper assembly to attach to the circumference of the battery shell in sequence, and to scrape the oil on all four sides of the battery shell at the same time, so as to recycle the excess stretching oil.

[0005] However, the aforementioned patented and existing battery casing oil scraping and trimming devices have some shortcomings: Existing methods using multiple braking mechanisms to drive cleaning components for simultaneous cleaning of all four sides of the battery casing are complex to operate, prone to processing deviations, resulting in low oil scraping efficiency. Therefore, those skilled in the art have provided a new energy battery square casing trimming mechanism with an oil scraping and trimming device, which completes the oil scraping process during the trimming process, reducing the need for separate oil scraping and cleaning / filtration processes, thus solving the problems mentioned in the background art.

[0015] As a further technical solution of this utility model: the reciprocating motion mechanism includes two sets of track frames horizontally installed on both sides of the support platform. Each set of track frames has a guide screw and a guide slide rail inside the support from top to bottom. The guide screw shaft is sleeved with a guide slide table that guides the guide slide rail.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-7This utility model provides a new energy battery square shell trimming mechanism with an oil scraping and trimming device, including a support platform 1. A reciprocating motion mechanism is installed above the platform of the support platform 1, and a support frame 5 is installed on the slide of the reciprocating motion mechanism. The reciprocating motion mechanism includes two sets of track frames 2 horizontally installed on both sides of the platform of the support platform 1. Each set of track frames 2 has a guide screw 10 and a guide slide rail 11 arranged from top to bottom inside the support. A transmission shell 3 is installed at one end of the support of the track frame 2, and a transmission mechanism is installed in the middle of the housing of the transmission shell 3. The output end of the motor 12 is equipped with a drive shaft 13, and both ends of the drive shaft 13 are equipped with bevel gears A14. One end of the shaft of each guide screw 10 is respectively provided with a bevel gear B15 that meshes with the bevel gear A14. By controlling the operation of the drive motor 12, the drive shaft 13 is driven to rotate, which in turn drives the bevel gears A14 to rotate. The meshing transmission between the bevel gears A14 and B15 drives the guide screw 10 to rotate synchronously, serving as a drive source to drive the corresponding components to operate.

[0035] A guide slide 4, which is guided by the guide rail 11, is sleeved on the outer side of the guide screw 10. The guide slide 4 supports the support frame 5. During the rotation of the guide screw 10, the guide slide 4 is pushed to slide along the track direction of the guide rail 11. Then, by using the reciprocating sliding of the guide slide 4, the combination of the support frame 5, the lifting air rod 6, and the fixture 7 is pushed to slide back and forth, so that the battery shell is circulated and fed to the oil scraping and trimming device 8 for oil scraping.

[0036] A lifting air rod 6 is installed at the top of the support frame 5, and a clamping fixture 7 is installed at the telescopic end of the lifting air rod 6. The clamping fixture 7 includes an integrally connected support base 71 and a clamping base 72. A rotary cylinder 73 is installed in the middle of the support base 71. Two sets of brake slide rails 75 are arranged in an alternating manner along the rotation direction of the rotary cylinder 73 inside the support base of the clamping base 72, and a brake slide table 76 is slidably connected to the guide rail of each set of brake slide rails 75. A clamping arm 74 is installed on the upper end of the frame of the two opposing sets of brake slide tables 76. The rotating end of the rotary cylinder 73 is equipped with... There is a brake gear 78, and brake racks 77 that mesh with the brake gear 78 are arranged in an alternating manner on one side of the frame of two sets of brake slides 76. By controlling the rotation of the rotary cylinder 73 to brake, the brake gear 78 is driven to rotate. The meshing transmission between the brake gear 78 and the two sets of brake racks 77 pushes the two sets of brake slides 76 to slide in opposite directions along the brake slide rail 75. Then, by using the opposite sliding of the brake slides 76, the two sets of clamping arms 74 are pushed to move in opposite directions and clamp into the inside of the battery case, clamping and fixing the battery case in an internal support manner.

[0037] An oil scraping and trimming device 8 is installed at one end of the platform of the support table 1 along the braking direction of the fixture 7, and an oil collection groove 9 fixed on the support table 1 is installed directly below the oil scraping and trimming device 8. The oil scraping and trimming device 8 includes a shearing knife seat 81 and a shearing knife 82 that are integrally connected. An oil scraping base 85 is installed in the inner wall of the shearing knife 82 in an embedded form. An oil scraping rubber strip 86 extending outward is provided on the inner wall of the oil scraping base 85. The number of oil scraping rubber strips 86 is also multiple, which is not limited in this utility model. An oil discharge groove 83 is opened on the seat surface of the shearing knife 82 along the circumference of the oil scraping base 85, and multiple sets of oil discharge holes 84 that penetrate the shearing knife seat 81 and the shearing knife 82 are arranged along the circumference of the groove bottom of the oil discharge groove 83.

[0038] In this embodiment, the shearing blade 82 is used to remove the burrs and excess segments from the opening of the square shell.

[0039] When the battery casing moves down along the oil scraping and trimming device 8, the oil scraping rubber strip 86 on the oil scraping base 85 contacts and scrapes the surface of the casing, removing excess stretching oil. The oil is then collected by the oil discharge groove 83 and discharged into the oil collection tank 9 through the oil discharge hole 84. When the battery casing moves up and resets along the oil scraping and trimming device 8, the oil scraping rubber strip 86 contacts and scrapes the surface of the casing again, removing the stretching oil from the surface of the casing. The scraped stretching oil is discharged into the oil collection tank 9 again. This process of simultaneously scraping the stretching oil on the surface of the battery casing from top to bottom improves the scraping efficiency and allows for simultaneous scraping of all four sides of the battery casing.

[0040] The working principle of this utility model is as follows: After the battery case is placed directly below the fixture 7, the rotary cylinder 73 of the fixture 7 is controlled to rotate and brake, which drives the brake gear 78 to rotate. The meshing transmission between the brake gear 78 and the two sets of brake racks 77 pushes the two sets of brake slides 76 to slide in opposite directions along the brake slide rail 75, and then pushes the two sets of clamping arms 74 to move in opposite directions, clamping the battery case in an internal support manner to hold and fix the battery case.

[0041] After the battery case is clamped and fixed, the drive motor 12 is controlled to work, which drives the drive shaft 13 to rotate. The meshing transmission of bevel gear A14 and bevel gear B15 drives the guide screw 10 to rotate synchronously, pushing the guide slide 4 to slide along the track direction of the guide slide rail 11, pushing the battery case on the fixture 7 to be fed to the oil scraping and trimming device 8 for oil scraping.

[0042] After the battery case is moved directly above the oil scraping and trimming device 8, the lifting air rod 6 is extended and braked to push the battery case on the fixture 7 downward into the oil scraping and trimming device 8. While moving downward, the oil scraping rubber strip 86 on the oil scraping base 85 contacts and scrapes the surface of the case to remove excess stretching oil. The oil is then collected through the oil discharge slot 83 and discharged through the oil discharge hole 84, circulating into the oil collection tank 9. When the lifting air rod 6 retracts and brakes, it drives the battery case to move upward along the oil scraping and trimming device 8 to reset. While moving upward, the oil scraping rubber strip 86 contacts and scrapes the surface of the case again to remove the stretching oil. The scraped stretching oil is discharged into the oil collection tank 9 again. The stretching oil on the surface of the battery case is scraped twice simultaneously from top to bottom. The stretching oil collected in the oil collection tank 9 can be circulated out through the drain valve 91. Then, the battery case is fed and scraped in a cyclical manner.

[0043] In particular, the long-side oil scraping rubber strip 861 is positioned above the short-side oil scraping rubber strip 862. It scrapes oil when the square shell moves downward and then upward. Because the long side adheres to more oil than the short side, the long-side oil scraping rubber strip 861 can scrape more during the downward and upward movements. When the production quantity of square shells is large, more oil can be saved for recycling, further reducing costs, reducing unnecessary oil scraping processes, and alleviating the burden on the cleaning and filtration processes.

[0044] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model. For example, it can be applied to scraping lubricating oil from the outer wall of a cylindrical metal casing, where the scraping rubber strip is annularly mounted on an outer ring blade or support. When the cylindrical casing and the outer blade undergo relative displacement, the same effect is achieved using the same principle. These improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
