Detailed Implementation

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0052] Please see Figure 1-8 This utility model provides a technical solution:

[0053] A battery cell electrolyte filling port cleaning device, comprising:

[0054] Unwinding assembly 1 is used to clamp and convey the cleanroom cloth along the X-axis; and

[0055] Fabric cutting component 2 includes:

[0056] Multiple carrier mechanisms 21 are located on one side of the conveying end of the unwinding assembly 1 and arranged along the Y-axis. The multiple carrier mechanisms 21 can travel back and forth with the cutting position and the transfer position together, and the distance between them increases linearly from the cutting position to the transfer position. The cutting position and the transfer position are arranged opposite to each other along the Y-axis.

[0057] The dripping assembly 222 is located on the side of the fabric cutting position away from the transfer position, and is used to drip liquid onto the cleanroom cloth on the plurality of carrier mechanisms 21 at the fabric cutting position.

[0058] It should be noted that: when the carrier mechanism 21 is moved to the cloth cutting position, the unwinding assembly 1 unwinds the cleanroom cloth to a fixed length, so that the cleanroom cloth is distributed on the upper part of multiple carrier mechanisms 21. The carrier mechanism 21 clamps the cleanroom cloth. At this time, multiple dripping assemblies 222 simultaneously drip solvent onto the cleanroom cloth corresponding to each carrier mechanism 21. The cloth cutting assembly 2 simultaneously cuts the cleanroom cloth between multiple carrier mechanisms 21. Subsequently, multiple carrier mechanisms 21 move the cleanroom cloth from the cloth cutting position to the transfer position with a linearly increasing spacing, so that the subsequent wiping motion assembly 3 can pick it up synchronously. Thus, multiple cleaning heads can clean multiple battery cells at one time on a single mechanism, resulting in high cleaning efficiency.

[0059] As an improvement, such as Figure 3 As shown, the supporting mechanism 21 includes:

[0060] Clamping components 211 are provided in multiple sets for clamping the cleanroom cloth conveyed by the unwinding assembly 1;

[0061] A guide component is provided below the clamping component 211 to guide the reciprocating movement of the clamping component 211 between the cutting position and the transfer position.

[0062] Furthermore, such as Figure 7-8 As shown, the clamping component 211 includes:

[0063] The support block 2111 is slidably connected to the upper part of the guide component and is used to support the clean cloth conveyed by the unwinding assembly 1 when it enters and exits.

[0064] A clamping plate 2115 is disposed above the bearing block 2111 and is used to clamp the cleanroom cloth in conjunction with the bearing block 2111.

[0065] A fixing block 2112 is fixedly connected to one side of the bearing block 2111, and a cylinder component 2113 is installed on the fixing block 2112 opposite to the side of the bearing block 2111.

[0066] The clamping plate 2115 is hinged to the fixing block 2112;

[0067] The upper end of the cylinder component 2113 is fixedly connected to a pull shaft 2114 for pushing the clamping plate 2115 to rotate around the hinge shaft 2116;

[0068] The lower end of the bearing block 2111 is slidably provided with a first guide rail 212, and the lower end of the first guide rail 212 is slidably provided with a second guide rail 213 along the Y-axis. The second guide rail 213 is fixedly installed on the upper end of the bearing platform 231, and the lower end of the second guide rail 213 is provided with a variable pitch transplanting cylinder for driving the first guide rail 212 to move along the second guide rail 213.

[0069] It should be noted that: such as Figure 5-6 As shown, initially, the clamping plate 2115 and the carrier block 2111 are separated. When the unwinding assembly 1 conveys the cleanroom cloth to the upper end of the carrier block 2111 located at the cutting point, the cylinder 2113 is activated. The cylinder 2113 pushes the pull shaft 2114 upward, and the pull shaft 2114 drives the clamping plate 2115 to rotate around the hinge shaft 2116, so that the clamping plate 2115 clamps the cleanroom cloth located at the upper end of the carrier block 2111 between the clamping plate 2115 and the carrier block 2111, preventing the cleanroom cloth from shifting when it is subsequently cut, thereby improving the cutting accuracy.

[0070] As an improvement, such as Figure 3 , Figure 5-6 As shown, the fabric cutting assembly 2 further includes a cutting mechanism 22 for cutting the cleanroom fabric at the cutting position into multiple segments. The cutting mechanism 22 includes:

[0071] Pneumatic scissors 221, located on one side of the supporting mechanism 21, are used to cut the cleanroom cloth at the cutting position;

[0072] The scissor moving cylinder 223 is located at the lower part of the pneumatic scissors 221 and is used to drive the pneumatic scissors 221 to move to the fabric cutting position.

[0073] Furthermore, the dripping component 222 is located at the upper end of the pneumatic scissors 221 and is used to simultaneously drip cleaning liquid onto the lint-free cloth during cutting.

[0074] It should be noted that, as Figure 5-6 As shown, after the cleanroom cloth is clamped between the clamping plate 2115 and the support block 2111, the scissor moving cylinder 223 synchronously drives multiple sets of pneumatic scissors 221 to move to the cutting position and cut the cleanroom cloth into multiple segments. At the same time, the dripping component 222 drips the solvent onto the corresponding cut cleanroom cloth on each support block 2111.

[0075] As an improvement, such as Figure 3 , Figure 5-6 As shown, the fabric cutting assembly 2 further includes a guiding mechanism 23, which includes:

[0076] The support platform 231 is located between the lower part of the support mechanism 21 and the cutting mechanism 22, and is used to support the support mechanism 21 and the cutting mechanism 22.

[0077] The guide groove 232 is provided in multiple sets and corresponds one-to-one with the multiple supporting mechanisms 21. The guide groove 232 is provided through the interior of the supporting platform 231, and the spacing between the multiple guide grooves 232 gradually increases from the cutting position to the transfer position.

[0078] The lower end of the bearing block 2111 extends into the guide groove 232 via a shaft.

[0079] It should be noted that: such as Figure 5-6 As shown, after the cleanroom cloth is cut into multiple segments and dripped, the variable-pitch transfer cylinder located at the lower end of the second guide rail 213 drives the clamping component 211 to move along the negative direction of the Y-axis via the first guide rail 212 until the carrier block 2111 moves from the cutting position to the transfer position and stops moving. During this process, the first guide rail 212 slides along the second guide rail 213. Under the guidance of the shaft located at the lower end of the carrier block 2111 by the guide groove 232, the carrier block 2111 is gradually dispersed along the first guide rail 212, so that the cleanroom cloth that was originally in a clustered state after being cut is dispersed, making it easier for the wiping motion component 3 to clamp the cut cleanroom cloth from the dispersed carrier block 2111.

[0080] As an improvement, such as Figure 1-4 As shown, the unwinding assembly 1 includes:

[0081] Dust-free fabric tray 11;

[0082] Cleanroom cloth gripper cylinder 14 is located on one side of the bottom of the cleanroom cloth tray 11 and is used to clamp one end of the cleanroom cloth wound on the outside of the unwinding assembly 1.

[0083] The cloth-pulling cylinder 13 is located between the cleanroom cloth gripper cylinder 14 and the cleanroom cloth tray 11, and is used to transport the clamped cleanroom cloth along the X-axis direction.

[0084] Furthermore, the unwinding assembly 1 also includes:

[0085] A conveying and pressing cylinder 12 is installed on the upper end of the fabric pulling cylinder 13. The lower end of the conveying and pressing cylinder 12 is provided with a pressure roller 15, which is used to press down and tension the clean cloth during the conveying process.

[0086] Brake 16 is located at the axis of the dust-free fabric tray 11 and is used to brake the dust-free fabric tray 11 when it stops unwinding.

[0087] It should be noted that, as Figure 2As shown, when the cleanroom wipe needs to be unwound from the cleanroom wipe reel 11, the cleanroom wipe gripper cylinder 14 clamps one end of the cleanroom wipe, and the cloth pulling cylinder 13 drives the cleanroom wipe gripper cylinder 14 to move gradually, so that the cleanroom wipe is unwound from the cleanroom wipe reel 11. During this process, the conveying pressing cylinder 12 drives the pressure roller 15 to press down on the cleanroom wipe, so that the cleanroom wipe is in a taut state, avoiding wrinkles in the cleanroom wipe during unwinding.

[0088] As an improvement, such as Figure 1 As shown, the fabric cutting assembly 2 is provided with a wiping motion assembly 3 in the Y-axis direction, and the wiping motion assembly 3 includes:

[0089] Y-axis lead screw module 31 is located in the Y-axis direction of the unwinding assembly 1;

[0090] Z-axis lead screw module 32 is slidably disposed on one side of Y-axis lead screw module 31 along the Y-axis direction;

[0091] Panel 33 is slidably disposed on one side of the Z-axis lead screw module 32 along the Z-axis direction;

[0092] Rotary clamping cylinders 34 correspond one-to-one with the bearing mechanism 21 and are installed on one side of the panel 33;

[0093] The dust-free gripper 36 is located at the lower end of the rotary clamping cylinder 34 and is used to grip the dust-free cloth on the carrying mechanism 21 at the transfer position.

[0094] Furthermore, the wiping motion assembly 3 also includes:

[0095] A cleaning head is located inside the dust-free gripper 36 and is used to press the dust-free cloth that has been gripped and moved to the battery cell injection port onto the battery cell injection port.

[0096] A rotary motor 35 is located at the upper end of the rotary clamping cylinder 34 and is used to drive a lint-free cloth to rotate and wipe the battery cell's liquid injection port.

[0097] It should be noted that: such as Figure 1As shown, after the cleanroom cloth is brought to the transfer position by the carrier block 2111, the Z-axis lead screw module 32 drives the cleanroom gripper 36 to move above the carrier block 2111 along the Y-axis lead screw module 31. The Z-axis lead screw module 32 drives the panel 33 to move downwards, and the panel 33 drives the cleanroom gripper 36 to move downwards to the cleanroom cloth at the upper end of the carrier block 2111. At this time, the cylinder 2113 drives the clamping plate 2115 to release the cleanroom cloth, and the cleanroom gripper 36 holds the cleanroom cloth. The cloth is clamped and lifted from the support block 2111 to the initial height of the cleanroom gripper 36. Then, the Z-axis lead screw module 32 drives the Y-axis lead screw module 31 to move along the negative direction of the Y-axis, so that the cleanroom cloth is brought to the cell liquid injection port. The rotating clamping cylinder 34 presses the cleanroom cloth at the cleanroom gripper 36 down to the cell liquid injection port. The rotating motor 35 drives the cleanroom cloth to rotate and wipe at the cell liquid injection port through the cleanroom gripper 36, thus completing the cleaning work of the cell liquid injection port.
