[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] It should be noted that the grinding part in this embodiment includes, but is not limited to, small battery pieces, and can also be other plates or sheets that need to have their edges ground. The specific selection can be made according to actual needs, and this application does not limit it here.

[0029] See Figure 1 , Figure 2 and Figure 7 , Figure 1 A structural diagram of a grinding apparatus according to an embodiment of this application is shown. Figure 2 It shows Figure 1 The diagram shows the structure of the grinding assembly 10 in the grinding device. Figure 7A cross-sectional view of the grinding wheel 12 is shown. An embodiment of this application provides a grinding apparatus, including a grinding assembly 10, a base 20, and an elastic member 30. The grinding assembly 10 includes a frame 11, a grinding wheel 12, and a rotating mechanism 13. The grinding wheel 12 is rotatably connected to the frame 11 and has a grinding portion 1201 for pressing and grinding a workpiece 40 to be ground. The grinding portion 1201 is circumferentially arranged around the wheel surface of the grinding wheel 12. The rotating mechanism 13 is connected to the frame 11 and is used to rotate the grinding wheel 12. The frame 11 is slidably disposed on the base 20. The elastic member 30 is connected between the frame 11 and the base 20. When the grinding portion 1201 presses against the edge of the workpiece 40 to be ground, the elastic member 30 is in a compressed state.

[0030] In the aforementioned grinding device, when the workpiece 40 to be ground is being ground, the edge of the workpiece 40 presses against the grinding section 1201. The frame 11, under pressure, slides along the base 20, causing the elastic element 30 to move accordingly. The elastic element 30 is simultaneously compressed, thus providing a buffering effect and preventing damage caused by hard contact between the workpiece 40 and the grinding section 1201. The rotating mechanism 13 drives the grinding wheel 12 to rotate. When the grinding wheel 12 rotates, it grinds the edge of the workpiece 40 through the grinding section 1201. Therefore, the device can grind the edge of the workpiece 40 and ensure grinding quality.

[0031] Please see Figure 1 , Figure 4 and Figure 5 For example, the grinding device also includes a pressure sensor 50, a push-pull mechanism 60, and a controller. Both the pressure sensor 50 and the push-pull mechanism 60 are electrically connected to the controller. The pressure sensor 50 is used to sense the pressure between the grinding section 1201 and the workpiece 40 to be ground. The push-pull mechanism 60 is connected to the base 20 and is used to push and pull the base 20 so that the grinding section 1201 presses against or releases the workpiece 40 to be ground. The direction in which the push-pull mechanism 60 pushes and pulls the base 20 is as follows: Figure 1 As shown by the double arrow X in the diagram. The controller is used to control the push-pull mechanism 60 to perform push-pull actions based on the resistance pressure. Thus, under the control of the controller, the push-pull mechanism 60 performs push-pull actions, which can flexibly adjust and control the resistance pressure between the grinding section 1201 and the workpiece 40 to be ground, so that the resistance pressure is controlled within a preset range, and the resistance position between the grinding head and the workpiece 40 to be ground can be precisely controlled, thereby improving the grinding quality of the workpiece 40 to be ground, avoiding damage caused by excessive resistance pressure, and avoiding insufficient resistance pressure that fails to perform the grinding function.

[0032] For example, when the workpiece 40 to be ground reaches the grinding position, the push-pull mechanism 60 pushes the base 20 to move toward the workpiece 40 to be ground. The base 20, the elastic member 30 and the grinding assembly 10 as a whole will move toward the workpiece 40 to be ground, so that the grinding part 1201 of the grinding wheel 12 presses against the workpiece 40 to be ground.

[0033] For example, when the grinding section 1201 presses against the workpiece 40 to be ground, the elastic element 30 is in a compressed state. The pressure sensor 50 can correspondingly sense the pressure between the grinding section 1201 and the workpiece 40 to be ground. The controller compares the magnitude of the pressure with a preset range and controls the push-pull mechanism 60 to perform a push-pull action, thereby adjusting the pressure to the preset range. Specifically, when it is determined that the pressure is greater than the preset range, the push-pull mechanism 60 is controlled to move the base 20 away from the workpiece 40 to be ground, thus reducing the pressure accordingly; conversely, when it is determined that the pressure is less than the preset range, the push-pull mechanism 60 is controlled to move the base 20 closer to the workpiece 40 to be ground, thus increasing the pressure accordingly.

[0034] The preset range can be flexibly adjusted and adapted based on the specific type, specifications, and dimensions of the workpiece 40 to be ground, and is not limited here.

[0035] Therefore, the grinding device in this application adopts a closed-loop control concept, which can accurately grind the edge of the workpiece 40 to be ground, avoid unnecessary damage to the workpiece 40, meet the high precision requirements of battery process for the edge of battery cells, improve the compatibility of battery cells of different specifications and sizes, and achieve efficient and automated grinding.

[0036] Please refer to the following: Figure 1 , Figure 4 and Figure 5 For example, pressure sensor 50 is connected between elastic member 30 and base 20. Thus, when elastic member 30 is subjected to compressive force, it applies force to pressure sensor 50, causing pressure sensor 50 to press against base 20. The pressure sensed by pressure sensor 50 is also the pressure between grinding section 1201 and workpiece 40 to be ground. Alternatively, pressure sensor 50 can be connected between elastic member 30 and frame 11, similarly sensing the pressure between grinding section 1201 and workpiece 40 to be ground.

[0037] In one specific embodiment, the pressure sensor 50 is connected to the base 20, and the elastic element 30 is, for example, a spring. The frame 11 is provided with a fixing hole 111. One end of the elastic element 30 extends into the fixing hole 111 and is thus connected to the frame 11, while the other end of the elastic element 30 extends out of the fixing hole 111 and presses against the pressure sensor 50. When the elastic element 30 extends into the fixing hole 111, the stability of the elastic element 30 is improved, and the frame 11 can move stably with high reliability.

[0038] For example, the push-pull mechanism 60 may include, but is not limited to, a linear motor module or a cylinder, as long as it can provide power along the path. Figure 1 Push or pull the base 20 in the direction indicated by the double arrow X shown in the diagram.

[0039] For example, the push-pull mechanism 60 in this application employs a linear motor module, specifically a high-precision servo drive. Furthermore, a high-precision pressure sensor 50 is used. Based on the pressure value collected by the pressure sensor 50, the feed amount of the feed servo is driven, thereby ensuring that the grinding pressure of the grinding wheel 12 is consistent during the grinding process.

[0040] Please see Figure 1 , Figure 4 and Figure 5 For example, the base 20 includes a support block 21 and a limiting block 22, with the limiting block 22 connected to the support block 21.

[0041] It should be noted that the "limiting block 22" in this embodiment can be a part of the "support block 21", that is, the "limiting block 22" and the "other parts of the support block 21" are integrally formed; or it can be an independent component that can be separated from the "other parts of the support block 21", that is, the "limiting block 22" can be manufactured independently and then combined with the "other parts of the support block 21" to form a whole.

[0042] For example, the frame 11 is slidably mounted on the support block 21. Specifically, the support block 21 is provided with a slide rail 211, and the frame 11 is provided with a slider 112, which is slidably mounted on the slide rail 211.

[0043] Specifically, the elastic element 30 is connected between the frame 11 and the limiting block 22. Furthermore, the elastic element 30 and the grinding part 1201 are aligned along the sliding direction of the frame 11. Thus, during the mutual pressing of the grinding part 40 and the grinding part 1201, the elastic element 30 is subjected to positive force and is compressed, preventing force skew and providing a good buffering effect. This improves the movement stability of the frame 11, thereby ensuring that the grinding pressure of the grinding wheel 12 remains consistent during the grinding process, thus improving the grinding quality of the product.

[0044] Please see Figure 1 , Figure 4 and Figure 5 For example, the pressure sensor 50 is connected to the limit block 22, the frame 11 is provided with a fixing hole 111, one end of the elastic member 30 extends into the fixing hole 111, and the other end of the elastic member 30 extends out of the fixing hole 111 and presses against the pressure sensor 50.

[0045] Please see Figures 1 to 3For example, the rotating mechanism 13 includes a drive motor 131, a drive shaft 132, a drive wheel 133, a driven wheel 134, a transmission component 135, and a driven shaft 136. The drive motor 131 is mounted on the frame 11. Both the drive shaft 132 and the driven shaft 136 are rotatably mounted on the frame 11. The drive wheel 133 is coaxially connected to the drive shaft 132, and the driven wheel 134 is coaxially connected to the driven shaft 136. The drive wheel 133 is connected to the driven wheel 134 via the transmission component 135. The driven shaft 136 is also coaxially connected to the grinding wheel 12. Thus, when the drive motor 131 is working, the drive motor 131 drives the drive wheel 133 to rotate via the drive shaft 132. The drive wheel 133 drives the driven wheel 134 to rotate via the transmission component 135. The driven wheel 134 drives the driven shaft 136 to rotate, and the driven shaft 136 drives the grinding wheel 12 to rotate synchronously.

[0046] For example, the transmission element 135 may include, but is not limited to, a transmission belt or transmission chain.

[0047] Please see Figure 1 , Figure 6 and Figure 7 For example, the grinding portion 1201 is a recessed portion facing the central axis of the grinding wheel 12. In this way, the grinding portion 1201 can contact the upper and lower sides of the edge of the workpiece 40 to be ground, thereby facilitating the removal of burrs on the upper and lower sides of the edge of the workpiece 40 to be ground, and the grinding quality meets the requirements.

[0048] Please see Figure 1 , Figure 6 and Figure 7For example, the grinding wheel 12 includes a first wheel 121 and a second wheel 122 coaxially arranged and connected to each other. The first wheel 121 is located above the second wheel 122, and the end of the first wheel 121 facing the second wheel 122 has a first sidewall 1211, which is set at an acute angle to the central axis of the grinding wheel 12. The end of the second wheel 122 facing the first wheel 121 has a second sidewall 1221, which is connected to the first sidewall 1211, and the second sidewall 1221 and the first sidewall 1211 cooperate to form a recess. The first wheel 121 has a first liquid collecting groove 1212 and a first liquid drain hole 1213. The first liquid collecting groove 1212 is located on the top end face of the first wheel 121, and the first liquid drain hole 1213 communicates with the first liquid collecting groove 1212, extending from the bottom wall of the first liquid collecting groove 1212 to the first sidewall 1211. Thus, during the grinding process of the grinding wheel 12, grinding fluid can be prepared so that the grinding fluid is introduced into the first collection tank 1212. The grinding fluid in the first collection tank 1212 can be discharged through the first drain hole 1213. The grinding fluid will flow to the edge of the workpiece 40 to be ground, which not only plays a lubricating role, but also prevents the edge of the workpiece 40 from burning due to excessive temperature at the contact point of the grinding part 1201, thereby improving the grinding quality of the workpiece 40.

[0049] It should be noted that the "second wheel 122" in this embodiment can be a part of the "first wheel 121", that is, the "second wheel 122" and the "other parts of the first wheel 121" are integrally molded; or it can be an independent component that can be separated from the "other parts of the first wheel 121", that is, the "second wheel 122" can be manufactured independently and then combined with the "other parts of the first wheel 121" to form a whole.

[0050] For example, the first collection tank 1212 is arranged circumferentially around the central axis of the first wheel 121. In this way, the first collection tank 1212 has a large volume, which facilitates the collection of grinding fluid.

[0051] For example, multiple first drainage holes 1213 are provided, and these multiple first drainage holes 1213 are arranged at intervals around the central axis of the first wheel 121. More specifically, the multiple first drainage holes 1213 are arranged at equal intervals around the central axis of the first wheel 121. In this way, during the grinding of the workpiece 40, grinding fluid flows downward through each first drainage hole 1213, thereby ensuring lubrication and improving grinding quality.

[0052] For example, the first drain hole 1213 is set at an angle to the central axis of the first wheel 121. The bottom end of the first drain hole 1213 is closer to the central axis of the first wheel 121 than the top end of the first drain hole 1213, which is beneficial for discharging the grinding fluid to the edge of the workpiece 40 to be ground.

[0053] For example, the second wheel 122 is provided with a second liquid collection tank 1222 and a second liquid discharge hole 1223. The second liquid collection tank 1222 is located at the end of the second wheel 122 facing the first wheel 121, and the bottom end of the second sidewall 1221 extends to the second liquid collection tank 1222. The second liquid collection tank 1222 communicates with the second liquid discharge hole 1223, which extends from the bottom wall of the second liquid collection tank 1222 to the bottom end face of the second wheel 122. In this way, after the grinding fluid flows past the edge of the workpiece 40 to be ground, it will flow downward along the second sidewall 1221 and flow to the second liquid collection tank 1222 for collection. The grinding fluid collected in the second liquid collection tank 1222 is then discharged outward in a timely manner through the second liquid discharge hole 1223.

[0054] For example, the second collection tank 1222 is arranged circumferentially around the central axis of the second wheel 122. In this way, the second collection tank 1222 has a larger volume, which facilitates the collection of grinding fluid.

[0055] For example, there are multiple second drainage holes 1223, which are arranged at intervals around the central axis of the second wheel 122. More specifically, the multiple second drainage holes 1223 are arranged at equal intervals around the central axis of the second wheel 122.

[0056] Please see Figure 1 , Figure 2 and Figure 4 In one embodiment, the frame 11 includes a first support arm 113, a second support arm 114, and a connecting arm 115. The first support arm 113 and the second support arm 114 are arranged at a distance from each other, and both the first support arm 113 and the second support arm 114 are connected to the connecting arm 115. The grinding wheel 12 is rotatably connected between the first support arm 113 and the second support arm 114.

[0057] Please see Figure 1 , Figure 2 and Figure 4 Based on the aforementioned embodiment, the first support arm 113 is located above the first wheel 121, and the first support arm 113 is provided with a liquid inlet channel 1131. One end of the liquid inlet channel 1131 is used to communicate with a supply device for providing grinding fluid, and the other end of the liquid inlet channel 1131 is arranged opposite to the first collection tank 1212. In this way, during the grinding process of the workpiece 40, the supply device outputs grinding fluid to the liquid inlet channel 1131, and the liquid inlet channel 1131 transports it to the first collection tank 1212, realizing a continuous supply of grinding fluid.

[0058] Please see Figure 1 , Figure 2 and Figure 4Based on the aforementioned embodiment, the second support arm 114 is located below the second wheel 122, and the second support arm 114 is provided with a third liquid collection tank 1141 and a drain channel 1142. The third liquid collection tank 1141 is located below the second drain hole 1223 and is used to collect the grinding liquid discharged from the second drain hole 1223. The drain channel 1142 is connected to the third liquid collection tank 1141. In this way, the third liquid collection tank 1141 can collect the grinding liquid discharged from the second drain hole 1223 and discharge it outward through the drain channel 1142. In addition, the drain channel 1142 is also used to connect to a waste discharge pipe. The waste discharge pipe discharges the grinding liquid into a waste liquid treatment device.

[0059] For example, the grinding wheel 12 is detachably mounted on the frame 11. In this way, the grinding wheel 12 can be replaced according to the actual needs of different types of grinding parts 40, thus making it suitable for grinding operations of more types of grinding parts 40.
