[0070] The embodiment of the present application provides a material cutting device for cutting a material so that the material can be used to wipe a workpiece later; the material can be a material strip or a cloth; the workpiece can be a battery cell or a shell. The embodiment of the present application is described by taking the material strip 200 as an example.

[0071] Figure 1 This is a front view of a cutting device provided in one embodiment of the present application. Figure 2 This is a front view of a cutting device in use according to an embodiment of the present application. Figure 1 and Figure 2 The cutting device provided in the embodiment of the present application includes a material loading component 1, a first pressing component 2, a cutting component 3, and a pressing component 4.

[0072] The material carrier assembly 1 is used for carrying the material tape 200 .

[0073] The first pressing assembly 2 is located around the carrier assembly 1 and can be pressed against the carrier assembly 1 to press the material strip 200 .

[0074] For example, in the height direction H of the cutting device, the first pressing assembly 2 is located above the material carrier assembly 1. Of course, according to actual conditions, the first pressing assembly 2 can also be located on the side of the material carrier assembly 1. The height direction H can be a vertical direction.

[0075] The first pressing assembly 2 may specifically include a pressing head and a pressing driving component. The pressing driving component is connected to the pressing head to drive the pressing head to move along the height direction H to abut against the material carrier assembly 1 to press the material strip 200 .

[0076] In the embodiments of the present application, one component abutting against another component means: when there is a material belt 200 between the two components, one component abuts against the other component indirectly through the material belt 200; when there is no material belt 200 between the two components, one component abuts against the other component directly. For example: when the carrier component 1 carries the material belt 200, the first clamping component 2 moves toward the carrier component 1 and abuts against the carrier component 1 indirectly, that is, abuts against the carrier component 1 through the material belt 200; when the carrier component 1 does not carry the material belt 200, the first clamping component 2 moves toward the carrier component 1 and abuts against the carrier component 1 directly.

[0077] The cutting assembly 3 is located on one side of the first pressing assembly 2 .

[0078] For example, in the length direction L of the cutting device, the cutting assembly 3 is located on the left side of the first pressing assembly 2. Of course, according to actual conditions, the cutting assembly 3 is located above the first pressing assembly 2.

[0079] The cutting component 3 is used to cut the material strip 200 .

[0080] The cutting component 3 may specifically cut the material strip 200 by a cutter, or may cut the material strip 200 by a laser.

[0081] The pressing assembly 4 is located at the other side of the first pressing assembly 2 and can be pressed against the carrying assembly 1 to press the material strip 200 .

[0082] For example, in the length direction L of the cutting device, the pressing assembly 4 is located on the right side of the first pressing assembly 2. Of course, the pressing assembly 4 can also be located above the first pressing assembly 2 according to actual conditions.

[0083] The material strip 200 is carried by the carrier component 1, and the first clamping component 2 approaches the carrier component 1 downward along the height direction H of the cutting device and is held against the carrier component 1 to clamp the material strip 200 located at the carrier component 1; the pressing component 4 located on the other side of the first clamping component 2 also approaches the carrier component 1 downward along the height direction H of the cutting device and is held against the carrier component 1 to clamp the material strip 200 located at the carrier component 1; in this way, the first clamping component 2 and the pressing component 4 jointly clamp the material strip 200 located at the carrier component 1; the cutting component 3 cuts off the material strip 200 clamped by the first clamping component 2 and the pressing component 4 on one side of the first clamping component 2.

[0084] According to the above content, it can be known that the carrier component 1 carries the material tape 200, the first clamping component 2 located around the carrier component 1 is pressed against the carrier component 1 to press the material tape 200, and the pressing component 4 located on the other side of the first clamping component 2 is pressed against the carrier component 1 to press the material tape 200. Since the material tape 200 located in the carrier component 1 is pressed by the first clamping component 2 and the pressing component 4, when the cutting component 3 cuts the material tape 200 on one side of the first clamping component 2, the position of the material tape 200 located in the carrier component 1 can remain basically unchanged, the position of the material tape 200 in the carrier component 1 can be fixed, and the material tape 200 can be carried flatly on the carrier component 1, which is convenient for subsequent grabbing of the material tape 200 to wipe the battery cell.

[0085] refer to Figure 1 and Figure 2 The above-mentioned cutting device may further include a material moving component 9.

[0086] The material moving assembly 9 is connected to the material carrying assembly 1 and the material pressing assembly 4 to drive the material carrying assembly 1 and the material pressing assembly 4 to move.

[0087] After the cutting assembly 3 cuts the material strip 200, the first clamping assembly 2 moves away from the carrier assembly 1 (for example, the first clamping assembly 2 moves upward along the height direction H of the cutting device and away from the carrier assembly 1), and releases the clamping of the material strip 200 located in the carrier assembly 1; the pressing assembly 4 keeps the pressing of the material strip 200 located in the carrier assembly 1 on the other side of the first clamping assembly 2, and the moving assembly 9 moves the carrier assembly 1 and the pressing assembly 4 to a specified position along the length direction L of the cutting device (for example, to the bottom of the clamping assembly), during which the pressing assembly 4 keeps the pressing of the material strip 200 located in the carrier assembly 1, and also always fixes the position of the material strip 200 in the carrier assembly 1 during the movement. After moving the carrier assembly 1 and the pressing assembly 4 to the specified position, the moving assembly 9 moves in the opposite direction, moves the carrier assembly 1 and the pressing assembly 4 back to their original positions, so as to carry and press a new section of the material strip, and repeats this process.

[0088] The material moving component 9 can specifically be a moving platform powered by a cylinder or a linear motor.

[0089] In some other embodiments, the material moving assembly 9 is optional, and after the material cutting assembly 3 cuts the material strip 200 , the clamping assembly moves to the position of the material carrying assembly 1 to clamp the material strip 200 .

[0093] The first pressing assembly 2 can be pressed against the second loading platform 12 (for example, the first pressing assembly 2 moves downwardly toward the second loading platform 12 along the height direction H and presses against the second loading platform 12 ) to press the material belt 200 on the second loading platform 12 .

[0094] In the length direction L of the cutting device, a first material clamping gap 101 exists between the first material loading platform 11 and the second material loading platform 12 .

[0095] The provision of the first clamping gap 101 facilitates the clamping assembly to move to the first clamping gap 101 to clamp the material strip 200 .

[0100] The first pressing assembly 2 can abut against the fourth loading platform 14 (for example, the pressing assembly 4 moves downwardly toward the fourth loading platform 14 along the height direction H and abuts against the fourth loading platform 14 ) to press the material strip 200 located on the fourth loading platform 14 .

[0101] In the aforementioned length direction L, a second material clamping gap 102 exists between the third material loading platform 13 and the fourth material loading platform 14 .

[0111] In the width direction W of the cutting device, there is a pressing opening 401 between the first part pressing head 411 and the second part pressing head 412 .

[0112] The setting of the pressing opening 401 facilitates the clamping assembly to press down the material strip 200 located 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 through the pressing opening 401 .

[0113] refer to Figure 4 The pressure head 41 is provided with a detection port 410 .

[0115] The material detection sensor 5 is located within the orthographic projection range of the detection port 410 of the pressure head 41 to detect whether there is a material tape 200 within the range of the detection port 410, so as to control the movement of the pressure head 41; specifically, if the material tape is detected, the pressure head 41 is controlled to move along the height direction H until it is against the first material loading platform 11 and the third material loading platform 13; if the material tape 200 is not detected, the pressure head 41 is kept stationary; the projection line of the aforementioned orthographic projection is parallel to the height direction H of the cutting device.

[0121] The first material blocking component 61 and the second material blocking component 62 are used to place the material roll of the material tape. Specifically, the material roll is located between the first material blocking component 61 and the second material blocking component 62.

[0122] One end of the unwinding shaft 63 is disposed on the first material blocking component 61 , and the other end of the unwinding shaft 63 passes through the second material blocking component 62 .

[0123] The material roll positioning component 64 is disposed on the unwinding shaft 63 to position the material roll.

[0124] The lock head 65 is detachably connected to the unwinding shaft 63 (specifically, is detachably connected to the portion of the unwinding shaft 63 that passes through the second material blocking component 62 ) to fix the second material blocking component 62 to the unwinding shaft 63 .

Figure 6 The embodiment of the present application further provides a wiping device, which includes the cutting device provided in any of the above embodiments. The wiping device can be a cell wiping device for wiping the liquid injection port of the cell or a shell wiping device for wiping the shell.

[0145] refer to Figure 6 The above-mentioned battery cell wiping device may further include a material taking component 20.

[0146] The material picking assembly 20 is disposed around the material carrying assembly 1 . The material picking assembly 20 is used to grab the material belt 200 located on the material carrying assembly 1 .

[0147] For example, the material picking assembly 20 moves to the first material clamping gap 101 to grab the material belt 200 located on the first material loading platform 11 and the second material loading platform 12 .

[0148] Figure 7 This is a schematic diagram of the structure of the material taking component of the cutting device provided in one embodiment of the present application. Figure 7 The above-mentioned material picking component 20 may specifically include a first claw component 21 and a second claw component 22.

[0149] The first claw member 21 and the second claw member 22 are used to clamp the material strip 200 together.

[0150] For example, 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.

[0151] In some other embodiments, the material picking component 20 may also be a suction cup mechanism, which absorbs the material belt 200 located on the material carrying component 1 to achieve material picking.

[0152] The material taking component 20 may further include a wiping head 23 .

[0153] The wiping head 23 can move toward the carrier assembly 1 along the height direction H of the cell wiping device, and press down the material belt 200 located on the carrier assembly 1, and abut against the surface of the material belt 200. The height direction of the cell wiping device is also the height direction of the cutting device.

[0154] The first claw member 21 and the second claw member 22 are located on both sides of the wiping head 23, and the first claw member 21 and the second claw member 22 can move to the vicinity of the wiping head 23 or move to abut against the wiping head 23, so as to clamp and fix the material belt 200 to the wiping head 23. The first claw member 21 and the second claw member 22 can move to the vicinity of the wiping head 23 because there is a space reserved between the first claw member 21 and the wiping head 23 for placing the material belt 200, and there is a space reserved between the second claw member 22 and the wiping head 23 for placing the material belt 200, and the first claw member 21 and the second claw member 22 abut against the wiping head 23 through the material belt 200.

[0155] The wiping head 23 can move to the first pressing gap 103 and the second pressing gap 104 to press the material belt 200 downward in the height direction and abut against the surface of the material belt 200. As the wiping head 23 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 are folded upward in the height direction H, 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. The first claw component 21 and the second claw component 22 clamp the folded part of the material belt 200 and fix it to the wiping head 23.

[0156] The wiping head 23 has a first side plane 231 and a second side plane 232 .

[0157] The first claw member 21 can move to the vicinity of the first side plane 231 or move to abut against the first side plane 231, and clamp the material strip 200 to the first side plane 231. The second claw member 22 can move to the vicinity of the second side plane 232 or move to abut against the second side plane 232, and clamp the material strip 200 to the second side plane 232, so that the material strip 200 is closely attached to the first side plane 231 and the second side plane 232 of the wiping head 23, and the material strip 200 can be stably clamped.

[0158] After the first claw member 21 and the second claw member 22 fix the material tape 200 to the wiping head 23, the wiping head 23 can specifically make the material tape 200 wipe the liquid injection port of the battery cell by translating or rotating relative to the battery cell.

[0159] Figure 8 A three-dimensional diagram of a material carrying assembly of a cutting device provided in another embodiment of the present application. Figure 8 The material loading assembly 1 may further include a material loading base 15 and a material receiving component 16 .

[0160] 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 .

[0161] The material receiving component 16 is movably arranged on 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 23.

[0162] When the wiping head 23 moves toward the material loading assembly 1 along the height direction H, as the wiping head 23 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 23 pushes the material belt 200 and the material receiving component 16 downward, and the wiping head 23 is abutted 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 23 and the material receiving component 16, which can prevent the material belt 200 from detaching from the wiping head 23, 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 23.

[0163] 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 23, 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.

[0164] The material receiving component 16 can be specifically located in the middle of the first loading platform 11, the second loading platform 12, the third loading platform 13 and the fourth 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 loading platform 11, the second loading platform 12, the third loading platform 13 and the fourth 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.

[0165] 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 .

[0166] In the width direction W of the battery cell wiping device, 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, which can support 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 when the material belt 200 is pressed by the wiping head 23, so that the material belt 200 can be folded more easily. The width direction of the battery cell wiping device is also the width direction of the cutting device.

[0167] 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.
