[0055] The embodiment of the present application provides a material clamping and wiping device, which is used to clamp a material (such as a material belt or cloth) to wipe a workpiece; the aforementioned workpiece may be a battery cell or a shell; when the workpiece is a battery cell, the material clamping and wiping device clamps the material belt to wipe the liquid injection port of the battery cell. Taking the battery cell 100 and the material belt 200 as an example, the embodiment of the present application is described.

[0056] Figure 1 This is a front view of a material clamping and wiping device provided in one embodiment of the present application. Figure 1 The material clamping and wiping device provided in the embodiment of the present application includes a material loading component 1 and a clamping component 2. The material loading component 1 and the clamping component 2 can be arranged on the same base or on different bases.

[0057] The material carrier assembly 1 is used for carrying the material tape 200 .

[0058] Figure 2A three-dimensional diagram of a material carrying assembly of a material clamping and wiping device provided in one embodiment of the present application. Figure 2 The loading assembly 1 includes a first loading platform 11 , a second loading platform 12 , a third loading platform 13 and a fourth loading platform 14 .

[0059] refer to Figure 2 , the first loading platform 11, the second loading platform 12, the third loading platform 13 and the fourth loading platform 14 are distributed in a rectangular shape. Of course, the first loading platform 11, the second loading platform 12, the third loading platform 13 and the fourth loading platform 14 can also be distributed in a parallelogram shape.

[0060] refer to Figure 2 In the length direction L of the material clamping and wiping device, there is a first material clamping gap 101 between the first material loading platform 11 and the second material loading platform 12, and there is a second material clamping gap 102 between the third material loading platform 13 and the fourth material loading platform 14.

[0061] refer to Figure 2 In the width direction W of the material clamping and wiping device, there is a first material pressing gap 103 between the first material loading platform 11 and the third material loading platform 13 , and there is a second material pressing gap 104 between the second material loading platform 12 and the fourth material loading platform 14 .

[0062] In the height direction H of the material clamping and wiping device, the first loading platform 11, the second loading platform 12, the third loading platform 13 and the fourth loading platform 14 have the same height, and the top surfaces of the first loading platform 11, the second loading platform 12, the third loading platform 13 and the fourth loading platform 14 are located in the same plane to jointly carry the same material strip 200, that is, the first loading platform 11, the second loading platform 12, the third loading platform 13 and the fourth loading platform 14 support different parts of the same material strip 200 (such as the four corners of the material strip 200). The aforementioned height direction H can be a vertical direction.

[0063] In some other embodiments, if the material strip 200 is relatively soft, the heights of the first material loading platform 11, the second material loading platform 12, the third material loading platform 13 and the fourth material loading platform 14 may be different in the height direction H of the material clamping and wiping device, and the material strip 200 can still be supported by the first material loading platform 11, the second material loading platform 12, the third material loading platform 13 and the fourth material loading platform 14.

[0064] Figure 3 A three-dimensional diagram of a clamping assembly of a material wiping device provided in one embodiment of the present application. Figure 3 The clamping assembly 2 is used to clamp the material strip 200 so as to subsequently wipe the liquid injection port of the battery cell 100 .

[0065] refer to Figure 3 The clamping assembly 2 includes a wiping head 20 , a first claw component 21 and a second claw component 22 .

[0066] The wiping head 20 can move to the first pressing gap 103 and the second pressing gap 104 to press the material belt 200 downward along the height direction and abut against the surface of the material belt 200 .

[0067] The first claw member 21 can move (such as rotate or translate) to the first clamping gap 101, and the second claw member 22 can move (such as rotate or translate) to the second clamping gap 102, so that the first claw member 21 and the second claw member 22 can jointly clamp the material strip 200.

[0068] Specifically, the first claw member 21 and the second claw member 22 are located on both sides of the wiping head 20 , and the first claw member 21 and the second claw member 22 move to the vicinity of the wiping head 20 or move to abut against the wiping head 20 , thereby clamping and fixing the material belt 200 to the wiping head 20 .

[0069] The first claw component 21 and the second claw component 22 can only move to the vicinity of the wiping head 20 because there is a space reserved between the first claw component 21 and the wiping head 23 for placing the material tape 200, and there is a space reserved between the second claw component 22 and the wiping head 23 for placing the material tape 200. The first claw component 21 and the second claw component 22 are supported on the wiping head 23 through the material tape 200.

[0070] In the embodiments of the present application, one component abutting against another component means: when there is a material tape 200 between the two components, one component abuts against the other component indirectly through the material tape 200; when there is no material tape 200 between the two components, one component abuts against the other component directly. For example: when there is a material tape 200 on the surface of the wiping head 20, the first claw component 21 and the second claw component 22 move toward the wiping head 20 and will indirectly abut against the wiping head 20, that is, abut against the wiping head 20 through the material tape 200; when there is no material tape 200 on the surface of the wiping head 20, the first claw component 21 and the second claw component 22 move toward the wiping head 20 and will directly abut against the wiping head 20.

[0071] Figure 4 This is a cross-sectional view of a portion of the structure of a material clamping and wiping device provided in one embodiment of the present application. Figure 4 The wiping head 20 has a first side plane 201 and a second side plane 202 .

[0072] The first claw member 21 can move to the vicinity of the first side plane 201 or move to abut against the first side plane 201 to clamp the strip 200 to the first side plane 201. The second claw member 22 can move to the vicinity of the second side plane 202 or move to abut against the second side plane 202 to clamp the strip 200 to the second side plane 202.

[0073] The first claw member 21 can only move to the vicinity of the first side plane 201 because a space for placing the material belt 200 is reserved between the first claw member 21 and the first side plane 201, and the first claw member 21 is held against the first side plane 201 by the material belt 200. The second claw member 22 can only move to the vicinity of the second side plane 202 because a space for placing the material belt 200 is reserved between the second claw member 22 and the second side plane 202, and the second claw member 22 is held against the second side plane 202 by the material belt 200.

[0074] Figure 5 A diagram of a material clamping and wiping device in use according to an embodiment of the present application. Figure 5 After the first claw member 21 and the second claw member 22 fix the material tape 200 to the wiping head 20 , the wiping head 20 can specifically move or rotate relative to the battery cell 100 to allow the material tape 200 to wipe the liquid injection port of the battery cell 100 .

[0075] The material belt 200 is supported on the first material loading platform 11, the second material loading platform 12, the third material loading platform 13 and the fourth material loading platform 14. When the wiping head 20 approaches the material loading component 11 along the height direction H of the material clamping and wiping device, a part of the wiping head 20 is located in the first material pressing gap 103, and another part of the wiping head 20 is located in the second material pressing gap 104. As the wiping head 20 is pressed down, the material belt 200 supported on the first material loading platform 11, the second material loading platform 12, the third material loading platform 13 and the fourth material loading platform 14 is folded upward in the height direction H, and the first The claw component 21 moves to the first clamping gap 101, and the second claw component 22 moves to the second clamping gap 102. The first claw component 21 and the second claw component 22 clamp and fix the folded part of the material strip 200 to the first side plane 201 and the second side plane 202 of the wiping head 20, so that the material strip 200 is tightly attached to the first side plane 201 and the second side plane 202 of the wiping head 20, which can achieve stable clamping of the material strip 200 and prevent the material strip 200 from falling from the wiping head 20 during the process of wiping the liquid filling port of the battery cell 100.

[0076] Figure 6 A three-dimensional diagram of a material carrying assembly of a material clamping and wiping device provided in another embodiment of the present application. Figure 6 The material loading assembly 1 may further include a material loading base 15 and a material receiving component 16 .

[0077] The first loading platform 11 , the second loading platform 12 , the third loading platform 13 and the fourth loading platform 14 are disposed on a loading base 15 .

[0078] The material receiving component 16 is movably arranged on the material loading base 15, that is, the material receiving component 16 is arranged on the material loading base 15 and can move relative to the material loading base 15. The area between the first material loading platform 11, the second material loading platform 12, the third material loading platform 13 and the fourth material loading platform 14 is empty, and the material receiving component 16 is located in this area. In addition, the first material clamping gap 101 is connected with the second material clamping gap 102 through this area; the first material pressing gap 103 is connected with the second material pressing gap 104 through this area, forming a material pressing area that can place the entire wiping head 20.

[0079] Figure 7 This is a front view of a material clamping and wiping device provided by another embodiment of the present application. Figure 7 When the wiping head 20 approaches the material loading assembly 1 along the height direction H, as the wiping head 20 presses the material belt 200 along the height direction H, the material receiving component 16 will support the material belt 200, and the wiping head 20 pushes the material belt 200 and the material receiving component 16 downward. The wiping head 20 is pressed against the material receiving component 16 in the first pressing gap 103 and the second pressing gap 104, so that the material belt 200 is located between the wiping head 20 and the material receiving component 16, which can prevent the material belt 200 from detaching from the wiping head 20, and facilitates the first claw component 21 and the second claw component 22 to clamp and fix the material belt 200 to the wiping head 20.

[0080] The material receiving component 16 can be specifically elastically connected to the material loading base 15, and can move relative to the material loading base 15 along the height direction H, can buffer the wiping head 20, and make the material receiving component 16 automatically return to its original position. Of course, the material receiving component 16 can also be connected to the material loading base 15 through a guide rail, a slider and a damper, and can also move relative to the material loading base 15 along the height direction H.

[0081] refer to Figure 6 The material receiving component 16 can be specifically located in the middle of the first material loading platform 11, the second material loading platform 12, the third material loading platform 13 and the fourth material loading platform 14. In this way, the material receiving component 16 can support the middle part of the material strip 200, so that the distances from the parts of the material strip 200 supported by the first material loading platform 11, the second material loading platform 12, the third material loading platform 13 and the fourth material loading platform 14 to the center of the material receiving component 16 are the same, so that the folding degrees of the various folded parts of the material strip 200 are the same, which can further improve the stability of the clamped material strip 200.

[0082] In some other embodiments, the material receiving component 16 is located at a position deviated from the middle of the first material loading platform 11 , the second material loading platform 12 , the third material loading platform 13 and the fourth material loading platform 14 .

[0083] refer to Figure 6In the width direction W, a part of the material receiving component 16 is located in the first pressing gap 103, and another part of the material receiving component 16 is located in the second pressing gap 104. When the material belt 200 is pressed down by the wiping head 20, the parts of the material belt 200 close to the first loading platform 11, the second loading platform 12, the third loading platform 13 and the fourth loading platform 14 can be supported, so that the material belt 200 can be more easily folded.

[0084] refer to Figure 3 and Figure 4 The clamping assembly 2 may further include a mounting assembly 23 , a connecting assembly 24 and a moving driving assembly 25 .

[0085] The connecting component 24 is movably disposed on the mounting component 23 , that is, the connecting component 24 is disposed on the mounting component 23 and can move relative to the mounting component 23 .

[0086] The first claw member 21 and the second claw member 22 are rotatably connected to the connecting component 24 .

[0087] The moving driving assembly 25 is connected to the connecting assembly 24 to drive the connecting assembly 24 to move relative to the mounting assembly 23 along the height direction H of the material clamping and wiping device, so that the first claw component 21 and the second claw component 22 can be opened or clamped.

[0088] The moving driving component 25 may specifically be a cylinder or a linear motor.

[0089] For example, the first claw component 21 and the second claw component 22 are rotatably connected to the connecting component 24, and the first claw component 21 and the second claw component 22 are also rotatably connected to the mounting component 23; when the mobile driving component 25 drives the connecting component 24 to move relative to the mounting component 23 along the height direction H of the clamping and wiping device, the first claw component 21 and the second claw component 22 rotate relative to the mounting component 23 around the connection with the mounting component 23, and the first claw component 21 and the second claw component 22 also rotate relative to the connecting component 24 around the connection with the connecting component 24, the first claw component 21 moves to the first clamping gap 101, and the second claw component 22 moves to the second clamping gap 102, thereby realizing the opening or clamping of the first claw component 21 and the second claw component 22 through a mobile driving component 25 (the first claw component 21 and the second claw component 22 can specifically be a connecting rod mechanism, and the opening or clamping is realized by rotation).

[0090] refer to Figure 3 and Figure 4The wiping head 20 is arranged on the connecting component 24 to follow the connecting component 24 to move relative to the mounting component 23 along the height direction H of the material clamping and wiping device, so as to clamp the material strip 200 with the first claw component 21 and the second claw component 22. A moving driving component 25 can drive the wiping head 20 to press down and realize the opening or clamping of the first claw component 21 and the second claw component 22, thereby simplifying the structure.

[0091] refer to Figure 3 and Figure 4 The material clamping and wiping device may further include a fixing seat 3.

[0092] The mounting assembly 23 of the clamping assembly 2 is rotatably disposed on the fixing seat 3, that is, the mounting assembly 23 is disposed on the fixing seat 3 and can rotate relative to the fixing seat 3. Since the first claw member 21 and the second claw member 22 are also connected to the mounting assembly 23, the mounting assembly 23 can drive the first claw member 21 and the second claw member 22 to rotate relative to the fixing seat 3 around an axis parallel to the height direction H, so that the material belt 200 wipes the liquid injection port of the battery cell 100.

[0093] refer to Figure 3 and Figure 4 The mounting assembly 23 may include a claw connection component 231 and a rotating component 232 .

[0094] The first claw member 21 and the second claw member 22 are rotatably connected to the claw connecting member 231 .

[0095] The rotating component 232 is connected to the claw connecting component 231 and is rotatably disposed on the fixing base 3 to drive the first claw component 21 and the second claw component 22 to rotate relative to the fixing base 3 around an axis parallel to the height direction H to wipe the liquid injection port of the battery cell 100 .

[0096] The connecting component 24 is passed through the claw connecting part 231 and the rotating part 232, and can move relative to the claw connecting part 231 and the rotating part 232 along the aforementioned height direction H, so that the first claw part 21 and the second claw part 22 rotate relative to the claw connecting part 231 around the connection with the claw connecting part 231, thereby making the first claw part 21 and the second claw part 22 open or clamped.

[0097] refer to Figure 3 and Figure 4 The above-mentioned installation component 23 may also include a overlapping component 233.

[0098] The rotating member 232 is connected to the claw connecting member 231 via the bridge member 233 .

[0099] In some other embodiments, the first claw component 21 and the second claw component 22 can also be cylinder clamps, which are driven to open and clamp by a separate power component. The power component with the first claw component 21 and the second claw component 22 is fixedly connected to the connecting component 24, and the first claw component 21 and the second claw component 22 can also be movably connected to the claw connecting component 231 of the mounting component 23, so as to move relative to the mounting component 23 and the connecting component 24 to achieve opening and clamping, and follow the mounting component 23 to rotate relative to the fixed base 3 around an axis parallel to the height direction H.

[0100] refer to Figure 3 and Figure 4 The connecting assembly 24 may include a connecting rod 241 and a connecting block 242 .

[0101] The connecting rod 241 is movably disposed on the mounting assembly 23. For example, the connecting rod 241 is movably disposed on the claw connecting component 231 and the rotating component 232 of the mounting assembly 23, for example, the connecting rod 241 penetrates the claw connecting component 231 and the rotating component 232.

[0102] The connecting block 242 is connected to the connecting rod 241 to move along the height direction H with the connecting rod 241 relative to the mounting assembly 23 .

[0103] The first claw member 21 and the second claw member 22 are specifically connected to the connecting block 242 of the connecting assembly 24 .

[0104] The wiping head 20 is disposed on the connecting rod 241 , specifically, on an end of the connecting rod 241 away from the moving driving assembly 24 , so as to move along the height direction H with the connecting rod 241 relative to the mounting assembly 23 .

[0105] In the aforementioned height direction H, the connecting block 242 is located between the claw connecting component 231 and the rotating component 232. The claw connecting component 231 is connected to the rotating component 232 through the overlapping component 233, which can fully utilize the space and make the structure compact.

[0106] refer to Figure 3 and Figure 4 The connecting component 24 may further include a force transmission component 243 .

[0107] The force transfer component 243 is arranged at one end of the connecting rod 241 close to the mobile driving component 25 to transfer the downward pressing force of the mobile driving component 25 to the connecting rod 241, so that the connecting rod 241 moves relative to the mounting component 23 along the height direction H. During this period, the force transfer component 243 follows the movement of the connecting rod 241.

[0108] The mobile driving component 25 and the force transmission component 243 can be floatingly connected to avoid rigid collision.

[0109] refer to Figure 3 and Figure 4 The material clamping and wiping device may further include a rotation driving component 4.

[0110] The rotation driving assembly 4 is connected to the mounting assembly 23 (eg, connected to the rotating component 232 of the mounting assembly 23 ) to drive the mounting assembly 23 to rotate around an axis parallel to the height direction H relative to the fixing base 3 .

[0111] refer to Figure 3 The material clamping and wiping device may further include a buffer component 5.

[0112] The buffer assembly 5 is connected to the fixing seat 3 .

[0113] The moving drive component 24 of the clamping component 2 is also connected to the fixing seat 3. When clamping the material belt 200 or wiping the liquid injection port of the battery cell 100, the force applied to the clamping component 2 can be transmitted to the buffer component 5 through the moving drive component 24 and the fixing seat 3, which can play a buffering role, so that the clamping component 2 can rebound when it hits the battery cell 100, and can avoid hard impact between the clamping component 2 and the battery cell 100, which can protect the clamping component 2, and can be designed with an anti-collision alarm to prevent the clamping component 2 from crushing the battery cell 100.

[0114] refer to Figure 5 The material clamping and wiping device may further include an object detection sensor 6.

[0115] The object detection sensor 6 is used to detect whether the clamping assembly 2 has grasped the material strip 200 and whether there is a battery cell 100 under the clamping assembly 2 .

[0116] The object detection sensor 6 may specifically be a light sensor.

[0117] The object detection sensor 6 can be specifically arranged on the fixing seat 3 .

[0118] refer to Figure 5 The above-mentioned material clamping and wiping device may also include a position detection sensor 7.

[0119] The position detection sensor 7 is used to detect whether the rotation drive assembly 4 returns to the correct position.

[0120] The position detection sensor 7 may specifically be a slot-type photoelectric sensor.

[0121] The working principle of the material clamping and wiping device provided in the embodiment of the present application is as follows:

[0122] The mobile driving assembly 24 moves downward along the height direction H and abuts against the force transmission component 243, so that the force transmission component 243, the connecting rod 241 and the connecting block 242 move downward along the height direction H relative to the claw connecting component 231 and the rotating component 232 of the mounting assembly 23, and the wiping head 20 arranged on the connecting rod 241 moves downward along the height direction H to approach the loading assembly 1. As the wiping head 20 is pressed downward, the material belt 200 supported on the first loading platform 11, the second loading platform 12, the third loading platform 13 and the fourth loading platform 14 moves downward in the height direction H is folded upward; since the first claw member 21 and the second claw member 22 are rotatably connected to the connecting block 242 of the connecting assembly 24, the first claw member 21 and the second claw member 22 can also be rotatably connected to the claw connecting member 231 of the mounting assembly 23, when the connecting block 242 of the connecting assembly 24 moves relative to the claw connecting member 231 of the mounting assembly 23 along the height direction H, the connecting block 242 pulls the first claw member 21 and the second claw member 22, and the first claw member 21 and the second claw member 22 are relatively connected around the connection with the connecting block 242. The connecting block 242 rotates, and the first claw member 21 and the second claw member 22 also rotate relative to the claw connecting member 231 around the connection with the claw connecting member 231, and the first claw member 21 moves to the first clamping gap 101, and the second claw member 22 moves to the second clamping gap 102. The first claw member 21 and the second claw member 22 clamp and fix the folded portion of the material strip 200 to the first side plane 201 and the second side plane 202 of the wiping head 20, so that the material strip 200 and the first side plane 201 and the second side plane 202 of the wiping head 20 are aligned. 2; the rotating driving component 4 drives the rotating component 232 and the claw connecting component 231 of the mounting component 23 to rotate relative to the fixed seat 3 around an axis parallel to the height direction H, and the claw connecting component 231 drives the first claw component 21 and the second claw component 22 to rotate relative to the fixed seat 3 around an axis parallel to the height direction H, so that the material belt wipes the liquid injection port of the battery cell 100; correspondingly, when the mobile driving component 24 moves upward along the height direction H, the wiping head 20 also moves upward along the height direction H, and the first claw component 21 and the second claw component 22 are opened.

[0123] The embodiment of the present application further provides a wiping device, which is used to wipe the liquid injection port of the battery 100. The aforementioned wiping device includes the material clamping wiping device provided by any of the above embodiments.

[0124] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
