[0050] The present application is further described in detail below in conjunction with the accompanying drawings. Figures 1 to 8 illustrate.

[0051] The present application provides an oil scraping device, which can be used to scrape off oil stains on the outer surface of a shell-like workpiece 2, for example, it can scrape off oil stains on the outer surface of an outer shell of a lithium battery, so that after most of the oil stains on the outer surface of the outer shell are scraped off, the difficulty of subsequent cleaning of residual oil stains on the outer shell is reduced, thereby improving the cleaning efficiency of the outer shell, and improving the overall production efficiency of the outer shell of the lithium battery as a whole;

[0052] like Figures 1 to 8 As shown, it is a structural schematic diagram of the oil scraping device 1 of the present application, the oil scraping device 1 includes a feeding mechanism 11 and an oil scraping mechanism, the workpiece 2 is arranged on the feeding mechanism 11, the feeding mechanism 11 is used to convey the workpiece 2 from which the oil has not been scraped off to the processing station of the oil scraping mechanism, so that the oil scraping mechanism scrapes the oil on the workpiece 2, and the feeding mechanism 11 then conveys the workpiece 2 from which the oil has been scraped off to the unloading position of the workpiece 2, the feeding mechanism 11 cooperates with the oil scraping mechanism, so that the oil scraping device 1 has an automatic oil scraping function, so that the oil scraping device 1 has automation performance, thereby saving labor costs and improving work efficiency.

[0053] like Figure 1 to Figure 2 , Figures 5 to 7 As shown, the feeding mechanism 11 includes a turntable 111 and a mounting assembly 112. The mounting assembly 112 is fixedly connected to the turntable 111. The mounting assembly 112 is used to fix the workpiece 2. The turntable 111 can rotate, and then the mounting assembly 112 drives the workpiece 2 to rotate together. The oil scraping station of the oil scraping mechanism is set on the rotation path of the mounting assembly 112, so that when the mounting assembly 112 drives the workpiece 2 to rotate with the turntable 111, the workpiece 2 will reach the oil scraping station of the oil scraping mechanism for oil scraping treatment;

[0054] like Figure 7 As shown, the mounting assembly 112 includes a mounting table and a support column, one end of the support column is connected to the mounting table, and the other end is connected to the turntable 111; the mounting table is basically a rectangular structure, the length and width of the workpiece 2 in the horizontal direction are basically the same as those of the mounting table, the length of the mounting table in the vertical direction is less than the length of the workpiece 2, and the workpiece 2 is mounted on the mounting table; a limit block is provided at the bottom of the mounting table, the limit block is used to support the bottom of the workpiece 2, so as to limit the workpiece 2 in the vertical direction, that is, the lower end of the workpiece 2 is abutted against the upper end of the limit block, so that the workpiece 2 cannot move downward, so that the workpiece 2 can be limited on the mounting assembly 112 in the vertical direction.

[0055] Further, such as Figure 7 As shown, the side wall of the mounting table is provided with a mounting bevel, which is located at the top of the mounting table and is inclined toward the center of the mounting table, so that the upper end of the mounting table is sharper, thereby making it easier to install the workpiece 2 on the mounting table.

[0056] In this embodiment, four groups of mounting components 112 are disposed on the turntable 111 .

[0057] like Figure 5As shown, the oil scraping mechanism includes a side wall oil scraping assembly 12, a top wall oil scraping assembly 14 and a driving assembly 13, wherein the top wall oil scraping assembly 14 and the side wall oil scraping assembly 12 are both arranged on the moving path of the workpiece 2, the top wall oil scraping assembly 14 is used to scrape off the oil stains on the top wall of the outer surface of the workpiece 2, and the side wall oil scraping assembly 12 is used to scrape off the oil stains on the peripheral wall of the outer surface of the workpiece 2;

[0058] In this embodiment, the top wall scraper assembly 14 includes a top wall scraper 141 and a support rod 142. The top wall scraper 141 is connected to the support rod 142. The top wall scraper 141 is in the shape of a long strip as a whole and is stationary relative to the workpiece 2. When the workpiece 2 rotates following the turntable 111, the workpiece 2 passes through the top wall scraper 141, and there is a slight friction between the top wall of the workpiece 2 and the top wall scraper 141, so that the top wall scraper 141 scrapes off the oil on the top wall of the workpiece 2; the setting position of the top wall scraper 141 on the support rod 142 can be adjusted, so that the top wall scraper 141 can be adapted to workpieces 2 of different heights to improve the applicability of the scraper device 1.

[0059] In this embodiment, the drive assembly 13 is a linear motor, which can directly convert electrical energy into linear motion mechanical energy, so that the side wall scraper assembly 12 can move linearly in the vertical direction. Figure 5 , Figure 7 As shown, the side wall scraper assembly 12 is connected to the driving assembly 13, and the driving assembly 13 can drive the side wall scraper assembly 12 to move up and down, and scrape off the oil stains on the outer peripheral side wall of the workpiece 2 during the up and down movement of the side wall scraper assembly 12; the side wall scraper assembly 12 includes a scraper plate 121, and the scraper plate 121 is provided with a scraper port 122 for the workpiece 2 to pass through, and the size of the scraper port 122 is adapted to the size of the workpiece 2. When the workpiece 2 passes through the scraper port 122, the side wall of the scraper port 122 fits with the workpiece 2, so that the workpiece 2 and the scraper plate 121 have slight friction, and then the scraper plate 121 scrapes off the oil stains on the side wall of the workpiece 2.

[0060] Furthermore, based on any of the above embodiments, the side wall scraping assembly 12 is further expanded; Figure 3 to Figure 4 As shown, the side wall scraper assembly 12 also includes a mounting plate 123 and a guide rail 124. The mounting plate 123 is a plate-shaped structure as a whole, and a through opening is provided thereon. The scraper opening 122 and the center line of the through opening are in the same straight line, and after the workpiece 2 reaches the scraper processing position of the side wall scraper assembly 12, the center line of the workpiece 2 and the scraper opening 122 are also in the same straight line; the area of ​​the through opening is larger than the area of ​​the scraper opening 122, and the scraper opening 122 and the through opening at least partially overlap, and when the side wall scraper assembly 12 scrapes the workpiece 2, the workpiece 2 passes through the scraper opening 122 and the through opening in sequence; the guide rail 124 is connected to the side wall scraper assembly 12, and the scraper plate 121 is connected to the mounting plate 123 through the guide rail 124;

[0061] like Figure 3 As shown, the scraper plate 121 is divided into a first scraper plate 1211, a second scraper plate 1212, a third scraper plate 1213 and a fourth scraper plate 1214. The four scrapers are all rectangular plates, and the ends are all flat. The first scraper plate 1211 and the second scraper plate 1212 are arranged in parallel and spaced apart. The first scraper plate 1211 and the second scraper plate 1212 have the same length, and the long side ends of the two scrapers are flush. The third scraper plate 1213 and the fourth scraper plate 1214 are respectively arranged at the opposite ends of the first scraper plate 1211 and the second scraper plate 1212. The third scraper 1213 and the fourth scraper 1214 are both fitted with the ends of the first scraper 1211 and the second scraper 1212, so that the inner walls of the first scraper 1211, the second scraper 1212, the third scraper 1213 and the fourth scraper 1214 form an oil scraping port 122. When the workpiece 2 passes through the oil scraping port 122, the first scraper 1211, the second scraper 1212, the third scraper 1213 and the fourth scraper 1214 correspond to the four side walls of the outer periphery of the workpiece 2, so as to scrape off the oil stains;

[0062] like Figure 4 As shown, each scraper is connected to the mounting plate 123 via two guide rails 124, so that each scraper can slide along the guide rails 124, thereby changing the size of the scraping port 122; wherein, the sliding directions corresponding to the first scraper 1211 and the second scraper 1212 are parallel to the short side directions thereof, and the sliding directions corresponding to the third scraper 1213 and the fourth scraper 1214 are parallel to the short side directions thereof.

[0063] Further, such as Figure 3 As shown, the side wall scraper assembly 12 also includes a linkage member 126, the two ends of which are respectively connected to two adjacent scrapers, and the linkage member 126 is rotatably connected to the scrapers. The linkage member 126 is used to enable the two adjacent scrapers to be linked. When one of the scrapers slides, the other scraper will be driven to slide through the linkage member 126, thereby realizing the linkage of the two scrapers. On the one hand, the size change of the scraper port 122 can have a uniform ratio. On the other hand, only one scraper needs to be controlled to realize the movement of four scrapers, thereby saving energy.

[0064] Further, such as Figure 3 , Figure 5 As shown, the side wall scraper assembly 12 also includes an adjustment assembly 125, which is connected to the second scraper 1212 and is used to drive the second scraper 1212 to slide along the guide rail 124; the adjustment assembly 125 includes a driving member and a connecting member 1251, one end of the connecting member 1251 passing through the mounting plate 123 is connected to the driving member, and the other end is connected to the second scraper 1212, as shown in FIG. Figure 4 , Figure 5As shown, the mounting plate 123 is provided with a groove for the connecting member 1251 to pass through, and the driving member is a cylinder. The driving member can push the connecting member 1251, so that the connecting member 1251 pushes the second scraper 1212 to slide; the connecting member 1251 is plate-shaped as a whole, and the second scraper 1212 is provided with a mounting groove that cooperates with the connecting member 1251. The connecting member 1251 passes through the mounting groove, and a limit plate is provided at the end of the connecting member 1251 that is connected to the second scraper 1212. The limit plate and the connecting member 1251 form an L shape, and the upper end surface of the limit plate is in contact with the lower end surface of the second scraper 1212. The limit plate limits the vertical displacement of the second scraper 1212, so that the connection between the second scraper 1212 and the mounting plate 123 is more stable.

[0065] Further improvements are made on the basis of the above embodiments, such as Figure 3 to Figure 4 As shown, the side wall scraper assembly 12 further includes a rebound assembly 127, which is connected to the first scraper 1211. The rebound assembly 127 makes the first scraper 1211 have a restorative property. When the force of the first scraper 1211 being pushed to slide and causing the scraper opening 122 to become larger disappears, the rebound assembly 127 can generate a rebound force, so that the first scraper 1211 can be reset. In addition, during the period when the first scraper 1211 is pushed to enlarge the scraper opening 122, the first scraper 1211 has a tendency to recover due to the rebound force, and then the scraper opening 122 can fit tightly with the outer contour of the workpiece 2, so that the scraper 121 has a better oil scraping effect on the workpiece 2.

[0066] like Figure 4 As shown, the rebound assembly 127 includes a fixed block 1271 and a spring 1272. The fixed block is connected to the mounting plate 123. One end of the spring 1272 is fixedly connected to the fixed block 1271, and the other end is fixedly connected to the scraper plate 121. A mounting hole is provided on the first scraper plate 1211 for inserting the spring 1272. The rebound direction of the spring 1272 is in the same straight line as the sliding direction of the first scraper plate 1211.

[0067] On the basis of any of the above embodiments, the oil scraping device 1 is further expanded; Figure 1 to Figure 2 , Figure 5As shown, the scraping device 1 also includes a detection mechanism 15, which is stationary relative to the workpiece 2. The detection mechanism 15 includes at least one detection sensor, which can be a photosensitive sensor. The specific type of the sensor is not limited here, as long as it can detect whether the workpiece 2 is installed; the detection mechanism 15 is arranged on both sides of the side wall scraping assembly 12, and the detection mechanism 15 is used to detect the workpiece 2 on the feeding mechanism 11, and can detect whether the workpiece 2 is installed on the feeding mechanism 11; when there is only one detection sensor, it gives priority to detecting the workpiece 2 to be scraped, and when it detects that there is no workpiece on the mounting assembly 112 2, the information can be transmitted to the background processing device, so that when the group of installation components 112 moves to the scraping station of the side wall scraping component 12, the background processing device can issue a command to make the side wall scraping component 12 not run, thereby saving resources and improving the accuracy of scraping oil; when there are two detection sensors, they can detect the workpiece 2 before and after scraping oil, on the one hand, detect whether the workpiece 2 is assembled on the installation component 112 to be scraped oil, and on the other hand, detect whether the workpiece 2 on the installation component 112 after scraping oil has been taken away, so as to cooperate with the subsequent unloading mechanism to take away the workpiece 2 after scraping oil, thereby improving the overall working efficiency of the scraping device 1. In this embodiment, with the cooperation of the detection mechanism 15, a mechanical gripper can be set to cooperate with placing the workpiece 2 to be scraped oil on the loading mechanism 11, and can also take away the workpiece 2 after scraping oil, thereby realizing the automation performance of the scraping device 1, reducing labor costs, and greatly improving work efficiency.

[0068] In actual use, Figure 1 , Figure 2 As shown, the workpiece 2 to be processed is placed on the mounting table of the loading mechanism 11. When the workpiece 2 passes through the top wall scraper 141 of the top wall scraper assembly 14, the top wall scraper 141 scrapes the oil on the top wall of the workpiece 2, and the turntable 111 continues to drive the workpiece 2 to rotate. The rotation of the turntable 111 drives the workpiece 2 whose top wall has been scraped with oil to the scraping station of the side wall scraper assembly 12. The turntable 111 stops rotating, and the scraper plate 121 in the side wall scraper assembly 12 moves down to scrape the oil on the outer peripheral wall of the workpiece 2, and then moves up for a second scraping. The turntable 111 drives the workpiece 2 to rotate. When the workpiece 2 rotates to the unloading station, the workpiece 2 that has been scraped with oil is taken away by a mechanical gripper or manually.

[0069] It should be noted that the various embodiments of the present application can be arbitrarily combined into a new embodiment if the solutions do not conflict and the technical solutions can coexist.

It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
