Description

Technical Field

[0001] This application relates to the technical field of burr grinding equipment, specifically to a R-angle burr grinding device. Background Technology

[0002] In existing machining processes, deburring involves a significant workload. In the production of power batteries and accessories, deburring is a crucial production step. After the aluminum shell is stretched, the small contact area between the processing die and the shell opening results in unidirectional extrusion, forcing out some metal and forming burrs. These burrs are located at the opening of the shell, and burrs may also be present at the rounded corners. If not removed, these burrs compromise the safety of the shell during subsequent use, posing a risk of battery fire. The presence of burrs not only affects the quality of parts but also impacts the performance, reliability, safety, and lifespan of subsequent products. Therefore, removing burrs from the rounded corners is essential.

[0003] Currently, most burr removal on the rounded corners of battery casing components is done manually by sanding. This method involves using sandpaper to slowly grind away the burrs on the rounded corners of the casing.

[0058] In order for those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure will be described in detail below in conjunction with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present disclosure and do not limit the present disclosure.

[0059] In the description of the present application, if the first, second is described only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the sequence of indicated technical features.

It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the above terms cannot be understood as limiting the present application.

[0061] The present application will be further described in detail below in conjunction with the drawings, see Figures 1 to 10 Description.

[0062] The present application provides an R corner burr polishing device for polishing the burr of the R corner part of the outer wall of the shell workpiece, which can remove the burr generated at the mouth part of the aluminum shell during the manufacturing process of the battery aluminum shell. The R corner burr of the shell workpiece is located at the end of the opening; such as Figure 1As shown, the R corner burr polishing device 1 of the present application comprises a workbench 11, a workpiece mounting seat 12 and at least one set of polishing assembly 13, the working plane of the workbench 11 is basically flat; the polishing assembly 13 and the workpiece mounting seat 12 are fixedly arranged on the workbench 11 surface of the workbench 11; the workpiece mounting seat 12 is used for mounting the workpiece 2, and the polishing assembly 13 is used for polishing the burr of the R corner of the workpiece 2 mounted on the workpiece mounting seat 12, so that the burr of the R corner part of the workpiece 2 is removed;

[0063] Among them, the polishing assembly 13 comprises a grinding groove 135, the grinding groove 135 is arranged inclinedly relative to the vertical direction, so as to have a blocking effect on the R corner of the workpiece 2 when moving along the vertical direction, the grinding groove 135 can act on the R corner of the workpiece 2, the grinding groove 135 cooperates with the side edge part of the workpiece 2, that is, the R corner part of the shell presents an outward convex arc-shaped protrusion, the grinding groove 135 is a groove, the recess direction of which is the same as the protruding direction of the R corner, so that the grinding groove 135 can be more fitted with the R corner, reducing the wear on other parts of the R corner and improving the wear rate of the burr;

[0064] Taking the workbench 11 surface of the workbench 11 as the horizontal plane, the workpiece mounting seat 12 can slide in the vertical direction relative to the workbench 11, as Figure 10 As shown, in the initial state when the workpiece 2 is mounted on the workpiece mounting seat 12, the lower end of the workpiece 2, that is, the R corner of the workpiece 2 to be polished, is higher than the lower end of the grinding groove 135, and then when the workpiece mounting seat 12 drives the workpiece 2 to move downward, the R corner of the workpiece 2 can act on the grinding groove 135 and generate friction with the grinding groove 135, so as to remove the burr on the R corner of the workpiece 2 by means of the friction force; in this embodiment, the gravitational potential energy generated when the workpiece mounting seat 12 moves downward is used to make the polishing process more labor-saving and convenient, reduce the labor intensity and improve the work efficiency.

[0065] In this embodiment, for the shell type workpiece 2 with R corner, the number of polishing assemblies 13 corresponds to the number of R corner parts to be polished. In this embodiment, the workpiece 2 has four R corner parts to be polished, and the number of polishing assemblies 13 is also four, which are arranged at positions corresponding to the R corner parts.

[0066] Further, as Figure 6As shown, the grinding groove 135 includes a grinding part 1351 and an extension part 1352 for grinding the R-angle of the workpiece 2. The surface of the grinding part 1351 is arc-shaped. The grinding part 1351 is the part of the grinding groove 135 that directly interacts with the R-angle of the workpiece 2. It is located at the center of the grinding groove 135, and its arc curvature matches the R-angle of the workpiece 2. In actual use, the curvature of the grinding part 1351 can be selected according to the R-angle curvature of the workpiece 2 to be ground, so as to increase the fit between the grinding part 1351 and the R-angle of the workpiece 2 and improve the burr grinding effect on the R-angle of the workpiece 2. Furthermore, as shown in 6, the grinding groove 135 also includes The grinding part 1352 is symmetrically arranged on both sides of the grinding part 1351. The grinding part 1352 is connected to the grinding part 1351 to form the opening of the grinding groove 135. The groove opening of the grinding groove 135 is a V-shaped groove with its opening facing the R-angle of the workpiece 2. The opening angle of the grinding groove 135 is between 100 degrees and 170 degrees. The advantage of this arrangement is that the grinding part 1351 of the grinding groove 135 can act on the R-angle of the workpiece 2, while the two sides of the grinding part 1351 will not contact the side wall of the workpiece 2, which can ensure the precise grinding of the burrs on the R-angle of the workpiece 2 by the grinding groove 135.

[0067] like Figure 6 As shown, this is one embodiment of the grinding groove 135. After the extension 1352 is connected to the grinding part 1351, the grinding groove 135 is in the shape of "}". In this embodiment, the extension 1352 of the grinding groove 135 includes a parallel section 13521. The parallel section 13521 is perpendicular to the opening direction of the grinding groove 135. That is, when the grinding groove 135 grinds the R-angle of the workpiece 2, the parallel section 13521 can be parallel to the side walls on both sides of the R-angle of the workpiece 2, which has a certain limiting effect on the workpiece 2. So that when the workpiece 2 is being ground, the grinding groove 135 has a limiting and stabilizing effect on the workpiece 2, so as to ensure that the burrs of the R-angle of the workpiece 2 can be ground cleanly and stably.

[0068] like Figure 7 As shown, another embodiment of the grinding groove 135 is formed by connecting the extension 1352 to the grinding part 1351, making the grinding groove 135 ">" shaped. The same as the above embodiment is that the surface of the grinding part 1351 is arc-shaped, the difference is in the shape of the extension 1352.

[0069] In another embodiment of this application, such as 8 to Figure 10As shown, the grinding groove 135 has an included angle with the vertical direction, and the included angle is 0-45 degrees. That is, the grinding groove 135 is inclined to the vertical direction with the vertical direction as the reference surface. The grinding groove 135 includes an upper end and a lower end. On the vertical plane of the R corner side ridge line of the workpiece 2, the R corner of the workpiece 2 is located between the lower end and the upper end of the grinding groove 135. Then, when the workpiece 2 is pressed down, the R corner of the workpiece 2 can act on the grinding groove 135 and the grinding groove 135 acts on the R corner. The workpiece 2 moves downward by overcoming the resistance of the grinding groove 135, so as to polish the burr of the R corner through the friction force. Further, with the vertical direction as the reference surface, the included angle θ between the grinding groove 135 and the vertical plane is formed. If the included angle θ is too large, when the workpiece 2 moves downward, the resistance to be overcome is large, which makes it difficult for the workpiece 2 to move downward. The friction force is too large, which can rub the parts other than the burr, thereby causing unnecessary wear of the workpiece 2. If the included angle is too small, the resistance is small when the workpiece 2 moves downward, and the friction force is too small, which can not be able to polish the burr of the R corner. Therefore, the included angle is 0-45 degrees, which can ensure the removal effect of the burr of the R corner by the grinding groove 135 and ensure that the workpiece 2 can move downward smoothly.

[0070] In another optional embodiment of the present application, as shown in Figures 7 to 8 The polishing assembly 13 includes a grinding block 131 and a mounting base 132. The mounting base 132 is arranged on the workbench 11 and is fixedly connected with the workbench 11. The grinding groove 135 is arranged on the grinding block 131. The grinding block 131 is slidably connected with the mounting base 132. In this embodiment, the grinding block 131 can slide relative to the mounting base 132. The sliding direction of the grinding block 131 is parallel and opposite to the direction of the grinding groove 135 towards the R corner of the workpiece 2. Therefore, when the workpiece 2 moves downward by overcoming the resistance of the grinding groove 135, the grinding block 131 can move backward under the pushing force of the workpiece 2, so that the workpiece 2 can move downward smoothly.

[0071] Further, as shown in Figure 8 The mounting base 132 is provided with a guide rail 134. The grinding block 131 is connected with the mounting base 132 through the guide rail 134. The guide rail 134 is arranged above the mounting base 132. The grinding block 131 is provided with a sliding groove matched with the guide rail 134. The guide rail 134 has a guiding and limiting effect on the sliding of the grinding block 131, so that the grinding block 131 can slide stably.

[0072] Further, as shown in Figure 8As shown, the polishing assembly 13 further comprises a sliding rod 133, and the mounting base 132 is L-shaped, comprising a bottom and a side portion, the guide rail 134 is arranged on the bottom, and the side portion is perpendicular to the bottom and located behind the sliding of the grinding block 131, and the side portion is provided with a connecting hole for the sliding rod 133 to pass through, the sliding rod 133 is in sliding connection with the mounting base 132, the sliding rod 133 is fixedly connected with the grinding block 131 through the mounting base 132, and the tail end of the sliding rod 133 connected with the mounting base 132 is connected with a nut for limiting, so that when the sliding rod 133 slides with the grinding block 131, the sliding rod 133 will not come out of the mounting base 132, and the setting of the sliding rod 133 has a certain guiding and limiting effect on the sliding of the grinding block 131, so that the grinding block 131 is relatively stable when sliding under the pushing force of the workpiece 2;

[0073] Further, the sliding rod 133 is sleeved with a spring, the spring is located between the mounting base 132 and the grinding block 131, one end of the spring abuts against the grinding block 131, and the other end of the spring abuts against the mounting base 132, so that after the grinding block 131 slides under the pushing force of the workpiece 2, the grinding block 131 has a reset function under the elastic force of the spring, the grinding block 131 can be reset under the action of the spring after the workpiece 2 is moved upward after polishing, so that the grinding block 131 can also polish the R-angle burr of the workpiece 2 when the workpiece 2 is moved downward next time, thereby improving the working efficiency of the polishing device.

[0074] In another embodiment of the present application, as shown in Figures 1 to 4 、 Figure 7 、 Figures 9 to 10 As shown, the workpiece mounting seat 12 comprises a mounting base 121, a fixed base 122 and a support column 123, the mounting base 121 is used for mounting the workpiece 2 and limiting the workpiece 2 in the horizontal direction and the vertical direction, that is, the workpiece 2 in the shell type can be sleeved on the mounting base 121, and the inner wall of the workpiece 2 is basically attached to the outer wall of the mounting base 121, so that the workpiece 2 can be stably connected to the mounting base 121 to ensure the stability of the workpiece 2 during polishing of the R-angle burr of the workpiece 2; the fixed base 122 is fixedly connected to the workbench 11 of the workbench 11, one end of the support column 123 is connected to the fixed base 122, and the other end of the support column 123 is connected to the mounting base 121, and the support column 123 is used for supporting the mounting base 121, as shown in Figure 3 、 Figure 10 As shown, the mounting base 121 is provided with a mounting hole for mounting the support column 123, and the support column 123 is in sliding connection with the mounting base 121 after passing through the mounting hole, so that the mounting base 121 can slide up and down along the support column 123 to ensure that the workpiece 2 can move in the vertical direction together with the mounting base 121.

[0075] In the embodiment, the support column 123 is two, which can ensure that the connection stability of the mounting base 121 and the fixing base 122 is better.

[0076] Further, as shown in Figure 10 , the support column 123 is sleeved with a buffer spring 124, one end of the buffer spring 124 abuts against the fixing base 122, and the other end abuts against the mounting base 121, so that the mounting base 121 has upward potential energy after moving downward, so that the mounting base 121 has an automatic reset function, and the buffer spring 124 can ensure that the buffer spring 124 absorbs part of the vibration generated by the burr grinding of the workpiece 2 when the workpiece 2 moves downward with the mounting base 121, so that the workpiece 2 is more stable during grinding.

[0077] Further, in an embodiment of the mounting base 121, as shown in Figure 4 , Figure 5 , the mounting base 121 comprises a mounting table 1211, and the mounting table 1211 is basically in a cuboid structure, and the top of the mounting table 1211 is used for supporting the top of the workpiece 2, that is, the length of the mounting table 1211 in the vertical direction is basically the same as that of the workpiece 2, so that the top of the workpiece 2 abuts against the top of the mounting table 1211, thereby limiting the workpiece 2 in the vertical direction, so that the workpiece 2 is not easily fallen off after being installed on the mounting table 1211.

[0078] Further, as shown in Figure 4 , Figure 5 , the side wall of the mounting table 1211 is provided with a mounting inclined surface 12121, and the mounting inclined surface 12121 is located at the top of the mounting table 1211 and is inclined to the center of the mounting table 1211, so that the upper end of the mounting table 1211 is relatively sharp, thereby making it more convenient to install the workpiece 2 on the mounting table 1211.

[0079] Further, as shown in Figure 4 , the R corner of the mounting table 1211 is provided with a buffer groove 12122, and the buffer groove 12122 is located on the side column of the mounting table 1211 and is recessed towards the inside of the mounting table 1211, which corresponds to the R corner of the workpiece 2, so that the workpiece 2 can be installed on the mounting table 1211, and the R corner of the workpiece 2 will not be too close to the workpiece 2, which will cause the workpiece 2 to be difficult to install and remove.

[0080] In another optional embodiment of the present application, as shown in Figure 1 , Figure 7 , Figures 9 to 10As shown, the R-angle burr polishing device 1 further comprises a blowing assembly 15 fixedly arranged on the workbench 11, the blowing assembly 15 is used for blowing away the burrs adhered on the workpiece mounting seat 12 and the polishing assembly 13. When the burr residues polished fall on the workpiece mounting seat 12, the installation stability of the workpiece 2 will be affected, and when the burr residues adhere to the grinding groove 135, the polishing effect of the polishing assembly 13 on the burrs of the workpiece 2 will be affected. Therefore, the blowing assembly 15 can blow away the adhered burrs to ensure the polishing effect of the polishing device.

[0081] Further, as shown in Figure 7 、 Figure 10 , the blowing assembly 15 comprises a first blowing part 151 and a second blowing part 152. The air nozzle of the first blowing part 151 faces the bottom of the mounting base 121, which is used for blowing away the burr residues adhered on the bottom of the mounting base 121. The second blowing part 152 is arranged at the lower end of the grinding block 131, and the blowing direction thereof is from bottom to top, which is opposite to the grinding groove 135. Therefore, the burr residues adhered on the grinding groove 135 can be blown off without affecting the polishing of the grinding block 131 and the workpiece 2.

[0082] In another optional embodiment of the present application, as shown in Figures 1 to 3 , the R-angle burr polishing device 1 further comprises a sensor 14 and a mechanical claw, which is not shown in the figure. The mechanical claw is used for mounting the workpiece 2 on the workpiece mounting seat 12, pressing down the workpiece mounting seat 12 with the mounted workpiece 2, and taking out the polished workpiece 2 from the workpiece mounting seat 12. The sensor 14 is used for sensing the position of the workpiece 2 in the vertical direction. When the sensor 14 can sense whether the corresponding position has the workpiece 2, it will send a signal to cooperate with the mechanical claw to press down the mounted workpiece 2, so as to realize the burr polishing of the workpiece 2. In this embodiment, under the cooperation of the sensor 14 and the mechanical claw, the R-angle burr polishing device 1 has an automatic polishing function, which reduces the labor intensity, realizes the function of automatic burr polishing, and greatly improves the work efficiency.

[0083] Further, in this embodiment, the mounting base 121 is further improved, as shown in Figure 3 、 Figure 7 、 Figure 10As shown, the mounting base 121 includes a mounting platform 1211 and a limiting platform 1212. The mounting platform 1211 is basically a cuboid structure. The length and width of the workpiece 2 in the horizontal direction are basically the same as those of the mounting platform 1211. The length of the mounting platform 1211 in the vertical direction is less than the length of the workpiece 2. The workpiece 2 is fitted onto the mounting platform 1211. The limiting platform 1212 is connected to the bottom of the mounting platform 1211. The limiting platform 1212 is used to support the bottom of the workpiece 2 and to limit the workpiece 2 in the vertical direction. That is, the limiting platform 1212 abuts against the bottom of the workpiece 2, so that the workpiece 2 cannot move down, thereby limiting the workpiece 2 in the vertical direction on the mounting base 121.

[0084] Furthermore, such as Figure 7 As shown, in the horizontal direction, the length of the limiting platform 1212 is less than the length of the mounting platform 1211, and the width of the limiting platform 1212 is greater than the width of the mounting platform 1211. This causes the wide side of the limiting platform 1212 to protrude from the bottom of the mounting platform 1211, allowing the bottom of the workpiece 2 to abut against the limiting platform 1212. The shorter length of the limiting platform 1212 ensures that the long side of the limiting platform 1212 does not protrude from the bottom of the mounting platform 1211. In other words, since the relative distance between the R-angles of the short sides of the mounting platform 1211 is relatively close, the corresponding distance between the two grinding components 13 is also relatively close. This reduces the obstruction and influence of the limiting platform 1212 on the grinding components 13, thereby ensuring that the workpiece 2 can smoothly rub against the grinding components 13 when it moves down, thus removing burrs.

[0085] In this embodiment, the sensor 14 is positioned at a height higher than the top of the mounting platform 1211 in the vertical direction, but lower than the top of the workpiece 2 when it is installed. That is, the sensor 14 is located between the top surface of the workpiece 2 and the top surface of the mounting platform 1211. When the workpiece 2 is installed on the mounting platform 1211, the sensor 14 can detect in a timely manner that the workpiece 2 has been installed.

[0086] The working process of the R-angle burr grinding device 1 of this application will be described below with reference to the accompanying drawings:

[0087] like Figure 4 , Figure 5As shown, workpiece 2 is fitted onto mounting platform 1211 from the top downwards. When the top wall of workpiece 2 can no longer move downwards, that is, when the top wall of workpiece 2 abuts against the top wall of mounting platform 1211, it indicates that workpiece 2 is installed. Then, mounting platform 1211 is pressed downwards, and mounting platform 1211 moves workpiece 2 downwards. During the downward movement, the R-angle of workpiece 2 rubs against the grinding groove 135 of grinding block 131, thereby grinding off the burrs of the R-angle. Grinding block 131 is pushed by workpiece 2 and moves backwards. When the downward force applied to workpiece 2 is removed, buffer spring 124 generates an upward pushing force, pushing mounting platform 1211 upwards to reset. The pushing force on grinding block 131 from workpiece 2 disappears, and it also resets.

[0088] like Figures 1 to 3 The diagram illustrates another implementation of the R-corner burr grinding device 1. The grinding of burrs on the R-corner portion of the workpiece 2, the structure and location of the grinding component 13 are the same as in the previous embodiment. The difference lies in the structure of the mounting platform 1211. This embodiment includes a sensor 14 and a mechanical gripper. In this embodiment, the installation, removal, and pressing down of the installed workpiece 2 are all performed by the mechanical gripper. When the sensor 14 detects that the workpiece 2 is installed on the mounting platform 1211, the mechanical gripper presses down on the workpiece 2. When the workpiece 2 is pressed to the bottom, the mechanical gripper releases the pressing force, the mounting platform 1211 resets, and the mechanical gripper removes the workpiece 2 from the mounting platform 1211, thus achieving automated burr grinding and improving work efficiency.
