[0040] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the formation of a more optimal connection structure by adding or reducing connection accessories according to specific implementation situations. Each technical feature in the creation of the present utility model can be combined interactively without mutual contradiction or conflict.

[0041] Referring to Figure 1 , a wiping device provided by an embodiment of the present utility model includes a cutting and wiping device, a frame and a control component. The automatic operation of the cutting and wiping device is realized through the control component, which improves the speed and accuracy in the cutting and wiping process, improves productivity and saves costs.

[0042] Referring to Figure 1 , the cutting and wiping device is arranged in the frame and includes: a rewinding mechanism 1, a dragging mechanism 2, a cutting mechanism 3, a receiving mechanism 4 and a clamping jaw mechanism 5; the rewinding mechanism 1 has a plurality of rewinding units 10 arranged at intervals, and the rewinding unit 10 includes a reel 101 for winding the wiping tape and a plurality of guide wheels 102 for guiding the wiping tape; the dragging mechanism 2 includes a grasping component 21 and a first driving component 22 drivingly connected to the grasping component 21, the grasping component 21 grasps the wiping tape led out by the guide wheels 102 in the reel 101, and the first driving component 22 pulls out the wiping tape through the grasping component 21; the cutting mechanism 3 includes a scissor component 31 located on one side of the wiping tape in a stretched state, and the scissor component 31 is used for cutting the wiping tape; the receiving mechanism 4 includes a receiving component 41 and a second driving component 42 drivingly connected to the receiving component 41, and the second driving component 42 is used for driving the receiving component 41 to move the cut wiping tape to the position to be clamped; the clamping jaw mechanism 5 is used for clamping the wiping tape at the position to be clamped for wiping.

[0043] Among them, the material of the wiping tape can be determined according to specific requirements, and the wiping tape in this case is described by a paper tape. Referring to Figure 3, there are three guide wheels 102 in this case, which are used to change the discharging direction of the wiping tape. The take-up reel 101 of the unwinding mechanism 1 is used to wind the wiping tape. During use, the dragging mechanism 2 pulls out the wiping tape located in the take-up reel 101, and then the cutting mechanism 3 cuts the pulled-out wiping tape into tapes of a fixed length, and then the material receiving mechanism 4 transports the cut wiping tape to the position to be clamped. Finally, the clamping mechanism 5 clamps the wiping tape at the position to be clamped and performs the wiping work. The cutting and wiping device of the present utility model has a more compact structure. Through reasonable layout, the wiping speed and accuracy are greatly improved, productivity is increased, and costs are saved.

[0044] In some embodiments, referring to Figure 2 , 3 , the unwinding mechanism 1 further includes: a material changing component 11, the unwinding unit 10 is arranged on the material changing component 11, and the moving direction of the material changing component 11 driving the unwinding unit 10 is perpendicular to the stretching direction of the wiping tape; a material sensor 12, which is used to detect the presence or absence of the wiping tape in the reel 101; when the material sensor 12 detects that there is no wiping tape in the reel 101, the material changing component 11 drives the next unwinding unit 10 to move to the feeding position for feeding. Specifically, there are four unwinding units 10, which are arranged on the material changing component 11 at intervals in sequence. During use, the wiping tape needs to be pulled out manually, and then the first unwinding unit 10 is placed at the corresponding discharging position to prepare for cutting. When the tape of the first unwinding unit 10 is used up, that is, when the material sensor 12 detects that there is no tape in the reel 101, the material changing component 11 will drive the four unwinding units 10 to move together. The first unwinding unit 10 moves away from the discharging position, and the second unwinding unit 10 will move to the discharging position for discharging and pass through the subsequent material process. And so on. When the second unwinding unit 10 is used up, continue the above steps to meet the requirement of automatic roll change. In addition, the number of unwinding units 10 can be set according to needs. The material changing component 11 is a platform driven by a cylinder. The unwinding unit 10 is arranged on this platform, and the cylinder is used to drive the platform to drive the unwinding unit 10 to move to complete the roll change operation.

[0045] Furthermore, continue to refer to Figure 2 , 3, the unwinding unit 10 further includes an unwinding bracket 103 for mounting the material tray 101 and the guide wheel 102. On the side of the unwinding bracket 103 where the wiping tape exits, there is a pressing member 104 and a feeding guide wheel 105. The pressing member 104 and the feeding guide wheel 105 cooperate to press the wiping tape, so that the wiping tape between the feeding tray 101 and the discharging end is tightened, avoiding the deviation of the wiping tape when the material tray 101 supplies materials. It should be noted that there is a damping between the material tray 101 and the unwinding bracket 103, and specifically, a damper can be set to achieve the damping effect. The pressing member 104 and the feeding guide wheel 105 are provided at the discharging position. That is to say, when the wiping tape passes between the pressing member 104 and the feeding guide wheel 105, the wiping tape between the material tray 101 and the discharging position will be in a tightened state, which can avoid the problem of the wiping tape deviating during the transmission due to the drooping of the wiping tape. Among them, one end of the pressing member 104 presses on the feeding guide wheel 105, and the other end is movably connected to the unwinding bracket 103. A spring is provided between the unwinding and the pressing member 104 to provide a pressure for the pressing member 104 towards the feeding guide wheel 105.

[0046] In some embodiments, referring to Figure 4 , the grasping assembly 21 includes a grasping claw 211 and a grasping cylinder 212. The grasping cylinder 212 is used to drive the grasping claw 211 to open or clamp; the first driving assembly 22 includes a first transverse movement part 221 and a first longitudinal movement part 222. The first transverse movement part 221 and the first longitudinal movement part 222 cooperate to drive the grasping assembly 21 to pull out the wiping tape. Specifically, the first transverse movement part 221 is a transverse movement track and a transverse movement cylinder. The transverse movement cylinder drives the grasping assembly 21 to reciprocate in a direction perpendicular to the wiping tape. The first longitudinal movement part 222 is a longitudinal movement track and a longitudinal movement cylinder, which is used to drive the grasping assembly 21 to move away from or close to the discharging position. When in use, the first transverse movement part 221 and the first longitudinal movement part 222 cooperate to make the grasping assembly 21 close to the discharging position of the wiping tape. The grasping cylinder 212 drives the grasping claw 211 to clamp one end of the wiping tape. At this time, the first longitudinal movement part 222 drives the whole grasping assembly 21 to move in a direction away from the discharging position, pulling out the wiping tape to the predetermined cutting position. At this time, one end of the wiping tape at the cutting position is pressed by the pressing member 104 and the feeding guide wheel 105, and the other end is clamped by the grasping claw 211. That is to say, the wiping tape is in a tightened state at this time. The tightened tape can be easily cut by the scissor assembly 31, and the situation of the tape not being cut continuously can be avoided.

[0047] In some embodiments, referring to Figure 5, the cutting mechanism 3 includes a second transverse movement part 32, the scissor assembly 31 is arranged on the second transverse movement part 32, and the second transverse movement part 32 is used to drive the scissor assembly 31 to approach the wiping tape; the scissor assembly 31 includes a plurality of scissors arranged horizontally at intervals and a plurality of scissor cylinders 311. The second transverse movement part 32 drives the scissor assembly 31 to move, so as to adjust the position of the scissor assembly 31 relative to the wiping tape, thereby improving the cutting accuracy and cutting efficiency. It can be understood that the second transverse movement part 32 includes a second transverse movement track and a second transverse movement cylinder, and is driven by the cylinder to realize the movement adjustment of the cutting mechanism 3. When the scissor assembly 31 moves to a predetermined position, the scissor cylinder 311 drives the scissors to cut the wiping tape. Specifically, the number of scissors can be 4.

[0048] Further, a pressing unit is also arranged on the second transverse movement part 32. The pressing unit includes a pressing cylinder and a pressing head. The lower unit is located between two adjacent scissors and can also be located at the corresponding position above the cut wiping tape. After the wiping tape is cut, the pressing cylinder drives the pressing head to press the cut wiping tape onto the material receiving mechanism 4. Further, the lower unit also includes a pressing-in place sensor to accurately control the pressing unit to press the cut tape onto the material receiving mechanism 4.

[0049] In some embodiments, referring to Figure 6 , the material receiving assembly 41 includes a variable pitch module 411 and a plurality of material receiving units 412 located on the variable pitch module 411. The distances between the plurality of material receiving units 412 can be adjusted by the variable pitch module 411. When the second driving component 42 drives the material receiving assembly 41 to the corresponding position of the cutting mechanism 3, that is, the position below the cut tape, the material receiving unit 412 can be accurately moved to the position below the cut tape through the variable pitch module 411. After the tape is pressed onto the material receiving unit 412 by the pressing unit, the second driving component 42 drives the material receiving assembly 41 to leave the material receiving position and enter the position to be clamped. Each material receiving unit 412 is accurately controlled by the variable pitch module 411 to enter the preset position to be clamped. Further, the material receiving unit 412 includes a material receiving base 4121 slidably connected to the variable pitch module 411, a lifting cylinder 4122 arranged on the material receiving base 4121, and a suction cup 4123 is arranged at the output end of the lifting cylinder 4122. The suction cup 4123 is used to adsorb the cut wiping tape. The material receiving unit 412 can move to the position corresponding to the cut tape on the variable pitch module 411 through the material receiving base 4121. The lifting cylinder 4122 extends to move the suction cup 4123 below the tape and cooperate with the pressing unit to adsorb the tape on the suction cup 4123. By adsorbing the tape with the suction cup 4123, the stability of the material receiving assembly 41 when transporting the tape can be improved.

[0050] In some embodiments, reference Figure 7 The clamping mechanism 5 includes a third driving assembly 51 and a plurality of clamping units 52; the third driving assembly 51 has a third transverse moving part 511 and a vertical moving part 512, and the third transverse moving part 511 cooperates with the vertical moving part 512 to drive the clamping unit 52 to approach the material receiving mechanism 4 and clamp the wiping material tape at the position to be clamped through the clamping unit 52. Specifically, the third transverse moving part 511 is used to drive the clamping unit 52 to move above the position to be clamped, and further drive the clamping unit 52 to move downward and toward the material tape through the vertical moving part 512. The third transverse moving part 511 is preferably a linear motor, and the vertical moving part 512 is preferably a linear motor.

[0051] Further, refer to Figures 7 - 9 The clamping unit 52 includes: a first frame 521 and a second frame 522 rotatably connected to the first frame 521; the first frame 521 is provided with a clamping cylinder 5211 and a clamping motor 5212, the second frame 522 is provided with a wiping portion 5221 and a clamping portion 5222, the second frame 522 is transmission-connected to the driving assembly, and the clamping motor 5212 is used to drive the second frame 522 to rotate relative to the first frame 521; the clamping portion 5222 includes a transmission connected to the clamping cylinder 5211 The movable member 5222a is hinged to the transmission member 5222a and is located at both sides of the wiping portion 5221; the clamping member 5222b includes a first clamping section and a second clamping section, the first clamping section and the second clamping section are connected at a "V" shape angle and are located on the same side of the plane where the wiping portion 5221 is located, and the clamping member 5222b is movably connected to the second frame 522; the clamping claw cylinder 5211 drives the transmission member 5222a and drives the clamping member 5222b to clamp or release the wiping material belt. After the clamping jaw unit 52 moves to the position to be clamped, the vertical moving part 512 drives the clamping jaw to approach the material belt and further applies pressure toward the material receiving part. At this time, the material belt is squeezed by the wiping part 5221 of the clamping jaw, and the two ends of the material belt are tilted. At this time, the clamping member 5222b is driven by the clamping jaw cylinder 5211 to clamp the wiping material belt, and then the clamping jaw unit 52 is moved to the position to be wiped through the cooperation of the third transverse moving part 511 and the vertical moving part 512. The clamping jaw motor 5212 drives the second frame 522 to rotate, thereby driving the wiping material belt and the wiping part 5221 to rotate, so as to wipe and clean the battery filling port. The clamping jaw is driven by the clamping jaw cylinder 5211 to clamp the material belt. Compared with the traditional clamping jaw, the clamping jaw can clamp tighter and more stably, and the material belt will not fall off. In addition, the clamping jaw structure with a multi-stage design can make the clamping jaw open to a greater extent and easier to clamp the material belt. Specifically, the number of the clamping units 52 can be determined according to actual workstation requirements, and the number of the clamping units 52 can be increased or decreased according to different requirements.

[0052] Furthermore, the wiping part 5221 is preferably a rubber-coated wiping head. The rubber coating treatment can protect the battery surface from being scratched during wiping. Refer to Figure 9 , on the wiping end face of the rubber-coated wiping head, there are convex ridges 5221a. Among them, the convex ridges 5221a can form different patterns, such as a cross shape. The convex ridges 5221a have a scraping effect when the wiping part 5221 rotates for wiping, improving the wiping efficiency.

[0053] The above is a specific description of the preferred embodiment of the present invention, but the present invention is not limited to the described embodiment. Those skilled in the art can also make various equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
