Description

Technical Field

[0001] This application relates to the field of oil scraping equipment technology, specifically to an oil scraping device for battery casings. Background Technology

[0002] In the existing technology, the casing of lithium batteries is often made by stamping flat aluminum plates into a box. During the production of the aluminum casing, stamping oil is applied to the aluminum plate to improve the lubrication during stamping. Therefore, the outer surface of the casing after stamping will be contaminated with oil.

[0003] However, existing technologies generally involve direct cleaning of oil stains. Due to the thick oil stains on the casing, direct cleaning is difficult and time-consuming, resulting in low cleaning efficiency and reduced overall production efficiency of lithium battery casings.

[0004] In summary, there is room for further improvement in the cleaning efficiency of oil stains on the outer surface of lithium battery casings. Summary of the Invention

[0014] Furthermore, the second scraper is divided into a first scraper, a second scraper, a third scraper, and a fourth scraper, with adjacent scrapers connected by a linkage.

[0015] The first scraper and the second scraper are arranged parallel to each other at intervals;

[0016] The third and fourth scrapers are respectively disposed at opposite ends of the first and second scrapers;

[0018] Furthermore, the oil scraping mechanism also includes an adjustment component, which is connected to the second scraper and is used to drive the second scraper to slide along the guide rail;

[0019] The adjustment assembly includes a drive component and a connector, with one end of the connector connected to the drive component and the other end connected to the second scraper.

[0020] Furthermore, the second oil scraping assembly also includes a rebound assembly, which includes a fixing block and a spring;

[0021] The fixing block is connected to the mounting plate, one end of the spring is connected to the fixing block, and the other end is connected to the first scraper.

[0022] Compared with the prior art, this embodiment has at least the following technical effects:

[0023] 1. The first oil scraping component scrapes off the oil stains on the top surface of the battery casing, and the second oil scraping component scrapes off the oil stains on the four sides of the battery casing. Thus, the second oil scraping component can scrape off the oil stains on the four sides at the same time with one drive, which has high working efficiency. The first oil scraping component and the second oil scraping component work together to completely remove the oil stains on the outer surface of the battery casing, improving working efficiency.

This makes reasonable use of resources and saves costs.

[0035] 2. By setting limiting pressure members on both sides of the top scraper, the limiting pressure members will press against the battery casing when the top scraper is scraping oil from the battery casing, thereby preventing the battery casing from deflecting and ensuring the working stability of the top scraper.

Detailed Implementation

[0050] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0051] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0052] Those skilled in the art should understand that in the disclosure of this application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0053] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 12 illustrate. Example 1

[0054] like Figures 1 to 5 The diagram shows the structure of the battery casing oil scraping device 1 provided in this application. The battery casing oil scraping device 1 is used to scrape off the oil stains on the outer surface of the lithium battery casing, thereby pre-treating the oil stains on the battery casing 2 to reduce the difficulty of subsequent cleaning of the battery casing 2. This reduces the difficulty of cleaning the oil stains on the battery casing 2, improves the cleaning efficiency, and improves the overall production efficiency of the lithium battery casing.

[0055] like Figure 1 As shown, the battery casing oil scraping device 1 includes a mounting base 3, a feeding mechanism and an oil scraping mechanism. The mounting base 3 is symmetrically arranged with two installation stations at both ends. Each installation station is used to install a set of feeding mechanism and oil scraping mechanism, so that the battery casing oil scraping device 1 has two working stations, which greatly improves the working efficiency.

[0056] The battery casing 2 is conveyed by a feeding mechanism, which transports the battery casing 2 from the loading point to the oil scraping point and then to the unloading point. This cyclical conveying greatly improves work efficiency. In this embodiment, the feeding mechanism includes a turntable 4 and a drive motor. The drive motor is connected to the turntable 4, thereby driving the turntable 4 to rotate. That is, the conveying path of the feeding mechanism is circular. The loading, oil scraping, and unloading of the battery casing 2 all take place on the turntable 4. This significantly reduces the oil scraping working space of the battery casing oil scraping device 1, greatly saving space. Figure 4 As shown, the feeding mechanism also includes an installation component, which includes an installation platform 6 and a support column. One end of the support column is connected to the installation platform 6, and the other end is connected to the turntable 4. The installation platform 6 is basically rectangular. The length and width of the battery housing 2 in the horizontal direction are basically the same as those of the installation platform 6. The length of the installation platform 6 in the vertical direction is less than the length of the battery housing 2. The battery housing 2 is fitted onto the installation platform 6. The side wall of the installation platform 6 is provided with an installation ramp. The installation ramp is located at the top of the installation platform 6 and is inclined towards the center of the installation platform 6, making the upper end of the installation platform 6 more pointed, thus making it easier for the battery housing 2 to be installed onto the installation platform 6. The bottom of the installation platform 6 is provided with a limiting seat 7. The limiting seat 7 is an outwardly protruding protrusion. The protrusion is located on the side of the bottom of the installation platform 6. The limiting seat 7 supports the bottom of the battery housing 2 to limit the battery housing 2 in the vertical direction. That is, the lower end of the battery housing 2 abuts against the upper end of the limiting block, so that the battery housing 2 cannot move down, thus limiting the battery housing 2 in the vertical direction to the installation component.

[0057] In this embodiment, the turntable 4 is provided with at least 4 sets of mounting components, which are symmetrically arranged on the turntable 4.

[0058] Furthermore, the four corners (also called R-corners) of the mounting platform 6 are concave inward to form grooves. This reduces the contact area between the battery housing 2 and the mounting platform 6, making it easier to install the battery housing 2 onto the mounting platform 6 or to remove it from the mounting platform 6. On the other hand, this design prevents the mounting platform 6 from impacting the R-corners of the battery housing 2, effectively protecting the battery housing 2.

[0059] like Figure 4As shown, the oil scraping mechanism includes a first oil scraping assembly 8 and a second oil scraping assembly 14. The first oil scraping assembly 8 and the second oil scraping assembly 14 are arranged sequentially along the conveying direction of the turntable 4, and the first oil scraping assembly 8 and the second oil scraping assembly 14 do not move with the rotation of the turntable 4. The first oil scraping assembly 8 is used to scrape off the oil stains on the top surface of the battery casing 2, and the second oil scraping assembly 14 scrapes off the oil stains on the four sides of the outer periphery of the battery casing 2. The first oil scraping assembly 8 includes a top scraper 11 and a first mounting bracket 10. The first mounting bracket 10 is rod-shaped, and the top scraper... The top scraper 11 is connected to the first mounting bracket 10. The top scraper 11 is a long strip and is stationary relative to the battery housing 2. When the battery housing 2 rotates with the turntable 4, the battery housing 2 passes by the top scraper 11. The top wall of the battery housing 2 rubs slightly against the top scraper 11, thereby scraping off the oil stains on the top wall of the battery housing 2. The position of the top scraper 11 on the first mounting bracket 10 can be adjusted so that the top scraper 11 can be adapted to battery housings 2 of different heights, thereby improving the applicability of the oil scraping device 1.

[0060] like Figure 4 As shown, the second oil scraping assembly 14 includes a drive member 15, a second oil scraper 17, and a second mounting bracket 16. The second oil scraper 17 and the drive member 15 are connected to the second mounting bracket 16. The drive member 15 is connected to the second oil scraper 17 and is used to drive the second oil scraper 17 to move up and down. During the up and down movement of the second oil scraping assembly 14, the oil on the outer peripheral sidewall of the battery housing 2 is scraped off. The drive member 15 is a linear motor, which can directly convert electrical energy into linear motion mechanical energy, so that the second oil scraper 17 can move linearly in the vertical direction. The second oil scraper 17 is provided with an oil scraping port 18 for the battery housing 2 to pass through. The size of the oil scraping port 18 is adapted to the size of the battery housing 2. When the battery housing 2 passes through the oil scraping port 18, the sidewall of the oil scraping port 18 interacts with the battery housing 2, so that the battery housing 2 and the second oil scraper 17 rub slightly, and then the second oil scraper 17 scrapes off the oil on the sidewall of the battery housing 2.

[0061] like Figures 2 to 3 As shown, the second oil scraping assembly 14 also includes a mounting plate 30 and a guide rail 29. The mounting plate 30 is a plate-shaped structure with an opening. The center line of the oil scraping port 18 and the opening is on the same straight line. After the battery housing 2 reaches the oil scraping processing position of the second oil scraping assembly 14, the center line of the battery housing 2 and the oil scraping port 18 is also on the same straight line. The area of ​​the opening is larger than the area of ​​the oil scraping port 18, and the oil scraping port 18 and the opening overlap at least partially. When the second oil scraping assembly 14 scrapes the oil from the battery housing 2, the battery housing 2 passes through the oil scraping port 18 and the opening in sequence. The guide rail 29 is connected to the second oil scraping assembly 14, and the second oil scraping blade 17 is connected to the mounting plate 30 through the guide rail 29.

[0062] like Figure 2 As shown, the second scraper 17 is divided into a first scraper 19, a second scraper 20, a third scraper 21, and a fourth scraper 22. All four scrapers are rectangular plates with flat ends. The first scraper 19 and the second scraper 20 are arranged in parallel and spaced apart. The first scraper 19 and the second scraper 20 are of the same length, and their long sides are flush. The third scraper 21 and the fourth scraper 22 are respectively located at the ends of the first scraper 19 and the second scraper 20, and the third scraper 21 and the fourth scraper 22 are in contact with the ends of the first scraper 19 and the second scraper 20. This forms an oil scraping opening 18 on the inner wall of the first scraper 19, the second scraper 20, the third scraper 21, and the fourth scraper 22. When the battery casing 2 passes through the oil scraping opening 18, the first scraper 19, the second scraper 20, the third scraper 21, and the fourth scraper 22 correspond to the four outer side walls of the battery casing 2, thereby scraping off the oil.

[0063] like Figure 4 As shown, each scraper is connected to the mounting plate 30 via two guide rails 29, allowing each scraper to slide along the guide rails 29, thereby changing the size of the oil scraping port 18; wherein, the sliding direction of the first scraper 19 and the second scraper 20 is parallel to the direction of their short side, and the sliding direction of the third scraper 21 and the fourth scraper 22 is parallel to the direction of their short side.

[0064] Furthermore, the top scraper 11, the first scraper 19, the second scraper 20, the third scraper 21, and the fourth scraper 22 are made of plastic material, which can reduce friction with the battery casing 2 and reduce wear.

[0065] like Figure 3 As shown, the second oil scraping assembly 14 also includes a linkage 25. The two ends of the linkage 25 are respectively connected to two adjacent scrapers. The linkage 25 and the scrapers are rotatably connected. The linkage 25 is used to enable the two adjacent scrapers to move together. When one scraper slides, it will drive the other scraper to slide through the linkage 25, thereby realizing the linkage of the two scrapers. On the one hand, it can make the size of the oil scraping opening 18 change in a uniform proportion. On the other hand, only one scraper needs to be operated to move all four scrapers, thereby saving energy.

[0066] Furthermore, such as Figure 2 , Figure 3 As shown, the oil scraping mechanism also includes an adjusting component 23, which is connected to the second scraper 20. The adjusting component 23 is used to drive the second scraper 20 to slide along the guide rail 29. The adjusting component 23 includes a driving member 15 and a connecting member 24. One end of the connecting member 24, after passing through the mounting plate 30, is connected to the driving member 15, and the other end is connected to the second scraper 20. Figure 3As shown, the mounting plate 30 has a mounting groove 32 for the connector 24 to pass through. The mounting groove 32 is recessed away from the oil scraper opening 18, so that when the connector 24 is engaged with the mounting plate 30, it will not affect the area of ​​the oil scraper opening 18. The driving component 15 is a cylinder, which can push the connector 24, thereby causing the connector 24 to push the second scraper 20 to slide. The connector 24 is plate-shaped as a whole. Figure 2 As shown, the second scraper 20 is provided with an installation groove that mates with the connector 24. The connector 24 passes through the installation groove. A limiting plate is provided at the end of the connector 24 that is connected to the second scraper 20. The limiting plate and the connector 24 form an L-shape. The upper end face of the limiting plate is in contact with the lower end face of the second scraper 20. The limiting plate limits the vertical displacement of the second scraper 20, making the connection between the second scraper 20 and the mounting plate 30 more stable.

[0067] Furthermore, such as Figure 3 , Figure 5 As shown, the second oil scraping assembly 14 also includes a spring-loaded assembly 26, which is connected to the first scraper 19. The spring-loaded assembly 26 enables the first scraper 19 to have a restorative property. The spring-loaded assembly 26 includes a fixing block 28 and a spring 27. The fixing block 28 is connected to the mounting plate 30. One end of the spring 27 is fixedly connected to the fixing block 28, and the other end is fixedly connected to the first scraper 19. The first scraper 19 has a mounting hole for the spring 27 to be inserted. The spring-loaded direction of the spring 27 is on the same straight line as the sliding direction of the first scraper 19. When the force that pushes the first scraper 19 to slide and enlarge the oil scraping opening 18 disappears, the spring-loaded assembly 26 can generate a restoring force, which enables the first scraper 19 to return to its original position. During the period when the first scraper 19 is pushed to enlarge the oil scraping opening 18, the restoring force makes the first scraper 19 always have a tendency to return, which makes the oil scraping opening 18 fit tightly against the outer contour of the battery housing 2, thereby making the second oil scraper 17 have a better oil scraping effect on the battery housing 2.

[0068] Furthermore, such as Figure 1 , Figure 4As shown, the battery casing oil scraping device 1 also includes a detection mechanism 31. The detection mechanism 31 is stationary relative to the battery casing 2. The detection mechanism 31 includes at least one detection sensor, which can be a photosensitive sensor. The specific type of sensor is not limited here, as long as it can detect whether the battery casing 2 is installed on the mounting assembly. The detection mechanism 31 is located on both sides of the second oil scraping assembly 14. The detection mechanism 31 is used to detect the battery casing 2 on the feeding mechanism, and can detect whether the battery casing 2 is mounted on the feeding mechanism. When there is only one detection sensor, it prioritizes detecting the battery casing 2 to be scraped. When the mounting assembly is detected... When the battery casing 2 is not present on the component, the information can be transmitted to the background processing device. This allows the background processing device to issue a command when the assembly moves to the oil-scraping station of the second oil-scraping assembly 14, preventing the second oil-scraping assembly 14 from operating, thus saving resources and improving oil-scraping accuracy. When there are two detection sensors, they can detect the battery casing 2 before and after oil scraping. On one hand, they detect whether the assembly to be scraped has a battery casing 2; on the other hand, they detect whether the battery casing 2 on the assembly after oil scraping has been removed. This allows the subsequent unloading mechanism to remove the scraped battery casing 2, improving the overall working efficiency of the oil-scraping device 1. In this embodiment, with the cooperation of the detection mechanism 31, a robotic gripper can be used to place the battery casing 2 to be scraped onto the feeding mechanism and remove the scraped battery casing 2, thereby achieving automation of the oil-scraping device 1, reducing labor costs, and greatly improving working efficiency.

[0069] In actual use, such as Figure 1 , Figure 4 As shown, the battery casing 2 to be processed is placed on the mounting platform 6 of the feeding mechanism. When the battery casing 2 passes the top scraper 11 of the top wall scraping assembly, the top scraper 11 scrapes off the oil on the top wall of the battery casing 2. The turntable 4 continues to drive the battery casing 2 to rotate. The rotation of the turntable 4 drives the battery casing 2, whose top wall has been scraped, to the scraping position of the second scraping assembly 14. The turntable 4 stops rotating, and the scraper in the second scraping assembly 14 moves down to scrape off the oil on the outer peripheral wall of the battery casing 2. Then it moves up to perform a second scraping. The turntable 4 drives the battery casing 2 to rotate. When the battery casing 2 rotates to the unloading position, the battery casing 2 that has been scraped is taken away by a robotic gripper or manually. Example 2

[0070] like Figures 6 to 12The diagram shown is a structural schematic of the battery casing oil scraping device 1 according to Embodiment 2 of this application. Unlike Embodiment 1, in this embodiment, the conveying component is a conveyor structure, including a conveyor belt 5. The mounting component is mounted on the conveyor belt 5, and the driving component includes a drive motor connected to the conveyor belt 5 via a transmission wheel, thereby driving the conveyor belt 5 to move. The mounting component can move along with the conveyor belt 5. In this embodiment, the working principle and specific configuration of the conveyor are existing technologies and will not be described in detail here. Figure 10 As shown, the limiting seat 7 is connected to the bottom of the mounting platform 6. The side of the limiting seat 7 protrudes outward parallel to the conveying direction. The upper surface of the limiting seat 7 is flat, so that the bottom of the battery housing 2 can fit with the limiting seat 7, thereby limiting the battery housing 2 and preventing it from moving down. This allows the battery housing 2 to be stably limited on the mounting assembly in the vertical direction.

[0071] In this implementation, such as Figure 6 , Figure 7 As shown, the feeding mechanism is connected to the mounting base 3, and the oil scraping mechanism is connected to both ends of the conveyor belt 5 of the feeding mechanism. The conveying direction of the feeding mechanism is on the worktable, and the planar conveying direction of the conveyor belt 5, that is, the conveying direction is a straight line. Unlike the above embodiment, since the worktable of the conveyor belt 5 is a straight line, the feeding area, the oil scraping area, and the unloading area are distributed along the conveying direction of the conveyor belt 5 in this embodiment. Multiple working surfaces can operate at the same time, thereby greatly improving work efficiency.

[0072] like Figure 8 , Figure 9 , Figure 11 As shown, the first mounting bracket 10 is an n-shaped rectangular frame, including two vertical support plates and one horizontal support plate. The two vertical support plates are respectively connected to the side walls at both ends of the conveyor belt 5, and the two ends of the horizontal support plate are respectively connected to the tops of the two vertical support plates. The first oil scraper 9 is a long rectangular plate, and its top end is connected to the horizontal support plate of the first mounting bracket 10. The long side of the first oil scraper 9 is vertically arranged, and the length of the first oil scraper 9 is greater than or equal to the vertical height of the battery casing 2. Figure 3 As shown, there are at least two first oil scraper blades 9, which are spaced apart and the spacing direction is perpendicular to the conveying direction. The distance between the two first oil scraper blades 9 is less than or equal to the distance between the left and right sides of the battery housing 2, so that the first oil scraper blades 9 can act on the battery housing 2 to scrape off the oil. When the distance between the two first oil scraper blades 9 allows the battery housing 2 to pass through, the two first oil scraper blades 9 rub against the left and right sides of the battery housing 2 respectively, thereby scraping off the oil on the left and right sides of the battery housing 2.

[0073] like Figure 9 , Figure 11As shown, the top scraper 11 is a plate-shaped structure with its long side perpendicular to the conveying direction. The top of the top scraper 11 is connected to the support plate of the first mounting bracket 10. The top scraper 11 is set on the conveying path of the battery housing 2. That is, when the battery housing 2 passes the first oil scraping assembly 8 along its conveying path, its top surface will interact with the top scraper 11, thereby scraping off the oil stains on the top surface of the battery housing 2.

[0074] In this embodiment, the top scraper 11 can be disposed between two adjacent first oil scraper plates 9.

[0075] Furthermore, such as Figure 9 , Figure 11 As shown, the top scraper 11 can also be spaced apart from the first oil scraper 9 in the conveying direction, but in the direction perpendicular to the conveying direction, the top scraper is still located between two adjacent first oil scrapers 9; the top scraper 11 is set on the incoming side of the battery housing 2, so that the battery housing 2 first passes through the top scraper 11 to scrape the oil, and then enters between the two first oil scrapers 9. By placing the top scraper 11 in front, the oil scraped off by the top scraper 11 is prevented from causing secondary pollution to the cleaned left and right sides.

[0076] Furthermore, the first oil scraper assembly 8 is further expanded; such as... Figures 8 to 9 , Figure 11 As shown, the first oil scraping assembly 8 also includes a limiting pressure member 12, which is connected to the support plate on the first mounting bracket 10. In the conveying direction, it is spaced apart from the top scraper 11. There are at least two limiting pressure members 12, which are arranged on both sides of the top scraper 11 in the conveying direction. This allows the limiting pressure members 12 to limit and press the front and rear sides of the battery housing 2, so that the battery housing 2 is subjected to balanced force and the risk of the battery housing 2 tipping over due to pressure on one side is reduced. The end of the limiting pressure member 12 near the battery housing 2 is provided with a roller 13, which can roll, thereby reducing the friction between the limiting pressure member 12 and the battery housing 2 and reducing the wear area.

[0077] Furthermore, the second oil scraper assembly 14 is further expanded; such as... Figure 8 , Figure 9As shown, the second mounting bracket 16 is structurally similar to the first mounting bracket 10. The second mounting bracket 16 includes two mounting vertical plates and one mounting horizontal plate. The mounting horizontal plate is connected between the two mounting vertical plates, and the two mounting vertical plates are respectively connected to the side walls at both ends of the conveyor assembly. The horizontal plate of the second mounting bracket 16 has mating holes. The driving component 15 passes through the mating holes and connects to the second oil scraper 17, thereby driving the second oil scraper 17 to move up and down to scrape off the oil stains on the front and rear sides of the battery housing 2. There are at least two second oil scrapers 17, which are spaced apart along the conveying direction. The two oil scrapers 17 are connected by a connecting plate with a guide rail 29. The guide rail 29 slides along the conveying direction. The driving cylinder is connected to the two oil scrapers 17, thereby driving the two oil scrapers 17 to slide along the guide rail 29, thereby changing the distance between the two oil scrapers 17 to adapt to battery housings 2 of different sizes and improve the applicability of the battery housing oil scraping device 1. The distance between the two oil scrapers 17 is less than or equal to the distance between the front and rear sides of the battery housing 2, so that the two oil scrapers 17 can interact with the battery housing 2 to scrape off the oil.

[0078] Furthermore, such as Figure 11 , Figure 12 As shown, the first scraper 9, the second scraper 17, and the top scraper 11 are all equipped with rubber plates. These rubber plates contact the battery casing 2 to scrape away oil stains. The rubber plates are relatively mild, reducing friction with the battery casing 2 and thus minimizing wear. In this embodiment, due to the rubber plates, the distance between the two first scraper plates 9 is greater than the distance between the left and right sides of the battery casing 2, and the distance between the two second scraper plates 17 is greater than the distance between the front and rear sides of the battery casing 2. The top scraper 11 is a certain distance from the top surface of the battery casing 2. After the rubber plates are installed, the distance between two adjacent first scraper plates 9 with rubber plates is equal to the distance between the left and right sides of the battery casing 2, and the distance between two adjacent second scraper plates 17 with rubber plates is equal to the distance between the front and rear sides of the battery casing 2. The distance between the top scraper 11 with rubber plates and the top surface of the battery casing 2 is zero, allowing the rubber plates to make full contact with the battery casing 2 and effectively scrape away the oil stains.

[0079] Furthermore, regarding the spacing between the adhesive plate and the battery casing 2, another embodiment is also included, namely, the spacing between two adjacent first oil scraper blades 9 with adhesive plates is smaller than the spacing between the left and right sides of the battery casing 2, the spacing between two adjacent second oil scraper blades 17 with adhesive plates is smaller than the spacing between the front and rear sides of the battery casing 2, and the spacing between the top scraper blade 11 with adhesive plates and the top surface of the battery casing 2 is less than zero, thereby enabling the adhesive plate to fully contact the battery casing 2, thereby increasing the oil removal effect.

[0080] like Figures 6 to 7 , Figure 10 As shown, the detection mechanism 31 is connected to the end of the workbench near the outlet. The detection mechanism 31 is connected to the left and right sides of the conveyor belt 5. It is set at the outlet end, that is, the part where the conveyor belt 5 is about to change from linear displacement to arc displacement. When the conveyor belt 5 enters the arc displacement, if the battery housing 2 is still installed on the mounting component, it will block the conveyor belt 5 from conveying, thus affecting the working state of the online oil scraping device 1. Therefore, a mechanism is set at the outlet end of the feeding mechanism to detect whether there is a battery housing 2 on the mounting component. It can promptly remind the staff or the robotic arm to remove the battery housing 2 from the mounting component at the outlet end; or transmit this information to the background control system to stop the operation of the feeding mechanism, thereby suspending the operation of the online oil scraping device 1 to prevent subsequent impact on the online oil scraping device 1, thus ensuring smooth operation and improving work efficiency.

[0081] In this embodiment, as Figure 6 , Figure 7 As shown, the oil scraping mechanism is located in the middle of the conveyor belt 5. The conveyor belt 5 is equipped with multiple mounting components distributed along the conveying direction. The detection mechanism 31 is located at the outlet end of the conveyor belt 5. The conveying direction of the conveyor belt 5 is from the inlet end to the outlet end. Multiple mounting components are provided on both sides of the conveyor belt 5 to facilitate the placement of the battery housing 2 on the mounting components by the operator or robotic arm before the conveyor belt 5 reaches the oil scraping mechanism. After the oil scraping mechanism removes the oil stains on the outer peripheral wall of the battery housing 2, there is enough space and time to remove the oil-scraped battery housing 2. This allows the online oil scraping device 1 to have multiple working surfaces at the same time, thereby greatly improving work efficiency.

[0082] like Figure 6 , Figure 7As shown, along the conveying direction, the mounting components are evenly distributed on the conveyor belt 5. Two sets of mounting components are arranged side by side, that is, the first oil scraping component 8 and the second oil scraping component simultaneously scrape the oil from the two battery housings 2. The first oil scraping component 8 includes three first oil scraping plates 9 and two top surface scraping plates 11 to form two oil scraping stations. The length of the second oil scraping plate 17 of the second oil scraping component 14 is greater than or equal to the length of the two battery housings 2 arranged side by side, so that the two battery housings 2 can be scraped simultaneously.

[0083] In actual use, such as Figure 6 As shown, the feeding mechanism is started, and the conveyor belt 5 is driven forward. Before the installation component reaches the oil scraping mechanism, the worker places the battery housing 2 on the installation component. The battery housing 2 first passes through the first oil scraping component 8. The battery housing 2 is first pressed by the limiting pressure member 12, and then acts with the top scraper 11. Then the battery housing 2 moves forward and acts with the first oil scraper 9 to scrape off the oil on the left and right sides. Then the top part that has been scraped off moves forward and is pressed by the limiting pressure member 12 on the other side. Then, as the battery housing 2 moves forward, after the battery housing 2 has completely passed through the first oil scraping component 8, the oil on the top, left and right sides of the battery housing 2 is scraped clean.

[0084] The battery casing 2 continues to move forward and enters the second oil scraping assembly 14. When the battery casing 2 enters the working position of the oil scraping assembly, the conveyor belt 5 stops, and the drive unit 15 of the second oil scraping assembly 14 drives the second oil scraping plate 17 to move downward. When the second oil scraping plate 17 moves downward, it interacts with the battery casing 2 to scrape off the oil stains on the front and rear sides of the battery casing 2. After the second oil scraping plate 17 moves downward to its limit position, the drive unit 15 drives the second oil scraping plate 17 to move upward to its initial position, and the conveyor belt 5 starts to operate. The conveyor belt 5 moves forward, and the battery casing 2, which has been scraped of oil stains by the second oil scraping assembly 14, moves forward, and can be picked up by the staff or robotic gripper.

[0085] If the battery casing 2 is not removed in time, and the battery casing 2 is carried by the conveyor belt 5 past the detection mechanism 31, the detection mechanism 31 will detect the presence of the battery casing 2 on the installation component at the exit end. The detection mechanism 31 will then transmit the detection information to the background control system to remind the staff or robotic arm to remove the battery casing 2 at the exit end in time, or to stop the operation of the conveyor belt 5 to avoid subsequent adverse effects.
