Description

Technical Field

[0001] This utility model relates to the field of wiping and cleaning technology, and in particular to a wiping mechanism. Background Technology

[0002] During workpiece production, it is often necessary to wipe away stains to ensure a good appearance. Traditional wiping mechanisms use unwinding and rewinding rollers to rotate the cleaning belt, and a pressure head presses down on the belt, creating friction between the moving belt and the workpiece to clean its surface. However, when the workpiece is covered with stubborn stains such as oil, the friction between the cleaning belt and the workpiece alone is insufficient to remove these stains, resulting in a relatively poor wiping effect. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a wiping mechanism with better wiping effect.

[0004] A wiping mechanism according to an embodiment of the present invention includes a liquid storage tank, a workpiece placement platform, a wiping module, and a position adjustment module. The liquid storage tank is used to store cleaning fluid; the workpiece placement platform is used to place workpieces; the wiping module includes a first mounting base, a pressure head, an unwinding roller, and a winding roller, all of which are mounted on the first mounting base. The unwinding roller is used to output the cleaning belt, the winding roller is used to receive the cleaning belt output by the unwinding roller, and the pressure head is used to tension the cleaning belt; the position adjustment module is connected to the first mounting base and is used to drive the pressure head to move between the liquid storage tank and the workpiece placement platform. When the pressure head is located in the liquid storage tank, it can cause the cleaning belt to absorb cleaning fluid; when the pressure head is located in the workpiece placement platform, it can cause the cleaning belt to come into contact with the workpiece on the workpiece placement platform.

[0005] A wiping mechanism according to an embodiment of the present utility model has at least the following technical effects:

[0006] In the operation of the wiping mechanism of this application, the cleaning belt is moved by the take-up roller, so that the unwiped cleaning belt segment is moved to below the pressure head. At this time, the pressure head abuts against the unwiped cleaning belt segment. The position adjustment module drives the first mounting base to move, thereby moving the pressure head to the liquid storage tank, so that the pressure head carries the unwiped cleaning belt segment to dip into the cleaning liquid in the liquid storage tank. When the unwiped cleaning belt segment is dipped in cleaning liquid, the position adjustment module drives the first mounting base to move, thereby moving the pressure head to the workpiece placement table, so that the pressure head carries the cleaning belt segment dipped in cleaning liquid directly above the first end of the workpiece on the workpiece placement table, ready to wipe the workpiece. When the pressure head drives the cleaning belt to wipe the workpiece, under the drive of the position adjustment module, the pressure head can first drive the cleaning belt towards The pressure head moves downwards to abut the first end of the workpiece, then drives the cleaning belt along the surface of the workpiece to the second end to complete the wiping of the workpiece surface. Next, the pressure head drives the cleaning belt upwards to move away from the second end of the workpiece. Then, the pressure head drives the cleaning belt horizontally to directly above the first end of the workpiece, completing one wiping cycle. During one wiping cycle, the pressure head drives the cleaning belt along a "U"-shaped movement path. To improve the cleanliness of the wiping mechanism, the pressure head can drive the cleaning belt through multiple wiping cycles as needed, wiping the workpiece surface multiple times. After the cleaning belt segment soaked in cleaning fluid has finished wiping, the take-up roller drives the cleaning belt to move a new, unwiped cleaning belt segment to below the pressure head. In the above-described wiping mechanism, the pressure head drives the cleaning belt to absorb cleaning fluid from the storage tank, causing the cleaning belt soaked in cleaning fluid to rub against the workpiece. The cleaning fluid reacts chemically with the stains on the workpiece, making it easier to wipe away the stains, thus resulting in a better wiping effect.

[0007] According to some embodiments of the present invention, a wiping mechanism includes a pressure head comprising a pressure seat and an absorbent element made of liquid-absorbing material. The pressure seat is connected to a first mounting seat, and the absorbent element is located at the lower end of the pressure seat and is used to abut against the cleaning belt.

[0008] According to some embodiments of the present invention, a wiping mechanism includes a pressure head further comprising an elastic buffer, and a pressure seat is connected to a first mounting seat via the elastic buffer. The elastic buffer provides a downward elastic buffering force to the pressure seat.

[0009] According to some embodiments of the present invention, a wiping mechanism further includes a material pulling structure, which is disposed on a first mounting base and located on the moving path of the cleaning belt. The material pulling structure is used to pull the cleaning belt.

[0010] According to some embodiments of the present invention, a wiping mechanism includes a material pulling structure comprising a mounting frame, a material pulling roller assembly, and a drive structure. The material pulling roller assembly is mounted on the mounting frame and located on the moving path of the cleaning belt. The drive structure is connected to the material pulling roller assembly via a gear set and can drive the cleaning belt to move via the material pulling roller. The drive structure is connected to the take-up roller via a transmission belt. The transmission ratio between the drive structure and the material pulling roller is greater than the transmission ratio between the drive structure and the take-up roller.

[0011] According to some embodiments of the present invention, a wiping mechanism includes a mounting frame comprising a first frame and a second frame. The first frame is slidably mounted on the second frame in a vertical direction, and two pull rollers of the pull roller assembly are respectively mounted on the first frame and the second frame.

[0012] According to some embodiments of the present invention, a wiping mechanism includes a position adjustment module comprising a horizontal adjustment structure and a lifting structure connected to each other. The horizontal adjustment structure is used to adjust the position of the wiping module in a first horizontal direction so that the pressure head can reciprocate above the liquid storage tank and the workpiece placement platform. The lifting structure is used to drive the wiping module to perform lifting and lowering movements.

[0013] According to some embodiments of the present invention, a wiping mechanism includes a horizontal adjustment structure comprising a first driver, a slide rail, and a slide base. The slide base is slidably disposed on the slide rail, which extends along a first horizontal direction. The first driver is connected to the slide base and is used to drive the slide base to slide along the slide rail. A lifting structure is disposed on the slide base and is connected to the wiping module.

[0014] According to some embodiments of the present invention, a wiping mechanism includes a lifting structure comprising a second driver and a second mounting base. The second driver is disposed on a slide and connected to the second mounting base, and is used to drive the second mounting base to perform lifting movements.

[0032] The following is for reference. Figures 1 to 5 A wiping mechanism according to an embodiment of the present utility model will be described in detail.

[0033] refer to Figure 1 According to an embodiment of the present invention, a wiping mechanism includes a liquid storage tank 100, a workpiece placement platform 200, a wiping module 300, and a position adjustment module 400. The liquid storage tank 100 is used to store cleaning liquid; the workpiece placement platform 200 is used to place workpieces; the wiping module 300 includes a first mounting base 310, a pressure head 320, an unwinding roller 330, and a winding roller 340. The pressure head 320, the unwinding roller 330, and the winding roller 340 are all mounted on the first mounting base 310. The unwinding roller 330 is used to output the cleaning belt 350, and the winding roller 340 is used to receive... The cleaning belt 350 output by the take-up and unwind roller 330 is tensioned by the pressure head 320. The position adjustment module 400 is connected to the first mounting base 310 and is used to drive the pressure head 320 to move between the liquid storage tank 100 and the workpiece placement table 200. When the pressure head 320 is located at the liquid storage tank 100, it can drive the cleaning belt 350 to pick up the cleaning liquid. When the pressure head 320 is located at the workpiece placement table 200, it can drive the cleaning belt 350 to abut against the workpiece on the workpiece placement table 200.

[0034] During the operation of the wiping mechanism in this application, the take-up roller 340 drives the cleaning belt 350 to move, so that the unwiped cleaning belt segment is moved below the pressure head 320. At this time, the pressure head 320 abuts against the unwiped cleaning belt segment. The position adjustment module 400 drives the first mounting base 310 to move, thereby moving the pressure head 320 to the liquid storage tank 100, so that the pressure head 320 carries the unwiped cleaning belt segment to pick up the cleaning liquid in the liquid storage tank 100. When the cleaning belt segment is soaked in cleaning solution, the position adjustment module 400 drives the first mounting base 310 to move, thereby moving the pressure head 320 to the workpiece placement table 200, so that the pressure head 320, carrying the cleaning belt segment soaked in cleaning solution, is directly above the first end of the workpiece on the workpiece placement table 200, ready to wipe the workpiece; when the pressure head 320 drives the cleaning belt 350 to wipe the workpiece, under the drive of the position adjustment module 400, the pressure head 320 can... First, the cleaning belt 350 is moved downwards to contact the first end of the workpiece. Then, the pressure head 320 moves the cleaning belt 350 along the surface of the workpiece to the second end to complete the wiping of the workpiece surface. Next, the pressure head 320 moves the cleaning belt 350 upwards to move away from the second end of the workpiece. Then, the pressure head 320 moves the cleaning belt 350 horizontally to directly above the first end of the workpiece, so that the cleaning belt 350 completes one wiping cycle of the workpiece. During one wiping cycle, the pressure head 320 moves the cleaning belt 350 along a "U"-shaped movement path. In order to improve the cleanliness of the wiping mechanism of this application, the pressure head 320 can drive the cleaning belt 350 to perform multiple wiping cycles as needed to wipe the surface of the workpiece multiple times. After the cleaning belt segment soaked in cleaning solution has been wiped, the cleaning belt 350 is moved by the take-up roller 340 so that a new, unwiped cleaning belt segment is moved below the pressure head 320. From the working process of the above wiping mechanism, it can be seen that the pressure head 320 drives the cleaning belt 350 to dip into the liquid storage tank 100 to make the cleaning belt 350 dipped in the cleaning liquid rub against the workpiece. Through the chemical reaction between the cleaning liquid and the stains on the workpiece, the stains are more easily wiped off the workpiece, thus making the wiping effect of the workpiece better.

[0035] Specifically, the cleaning belt 350 is a lint-free cloth, the unwind roller 330 is manually expandable, and the take-up roller 340 is equipped with a clamping bar 341, which is used to cooperate with the take-up roller 340 to clamp one end of the cleaning belt 350. It can be understood that setting the unwind roller 330 to be manually expandable facilitates the quick clamping of the cleaning belt 350.

[0036] refer to Figure 3In some embodiments, the pressure head 320 includes a pressure base 321 and an adsorption member 322 made of liquid-absorbing material. The pressure base 321 is connected to the first mounting base 310, and the adsorption member 322 is located at the lower end of the pressure base 321 and is used to abut against the cleaning belt 350. Understandably, the take-up roller 340 drives the cleaning belt 350 to move, so that the unwiped cleaning belt segment is moved below the adsorption member 322. At this time, the adsorption member 322 abuts against the unwiped cleaning belt segment. The position adjustment module 400 drives the adsorption member 322 to move to the liquid storage tank 100. The adsorption member 322 drives the cleaning belt 350 to absorb the cleaning liquid. Since the adsorption member 322 is made of liquid-absorbing material, the cleaning liquid will be absorbed and stored in the adsorption member 322. Then, the position adjustment module 400 drives the adsorption member 322 to move to the workpiece, and the adsorption member 322 drives the cleaning belt 350 to abut against the workpiece. Since the unwiped cleaning belt segment is transported to the lower end of the adsorption member 322 and abuts against it, the cleaning liquid in the adsorption member 322 can be released into the cleaning belt 350. Then, the cleaning belt 350 dipped in cleaning liquid completes the wiping of the workpiece. By setting up the adsorption component 322, the number of times the pressure head 320 drives the cleaning belt 350 to dip into the cleaning liquid in the liquid storage tank 100 can be reduced, thereby further improving the wiping efficiency.

[0037] In a specific embodiment of this utility model, the adsorption element 322 is a cleanroom cloth, and the pressure head 320 also includes two locking blocks 324. The locking blocks 324 are connected to the pressure base 321 by threaded fasteners. The two locking blocks 324 cooperate with the pressure base 321 to clamp and fix the opposite ends of the cleanroom cloth. It can be understood that by using the detachable locking blocks 324 to clamp the cleanroom cloth with the pressure base 321, it is convenient to replace the cleanroom cloth.

[0038] refer to Figure 3 In one embodiment, the pressure head 320 further includes an elastic buffer 323. The pressure seat 321 is connected to the first mounting base 310 through the elastic buffer 323. The elastic buffer 323 provides a downward elastic buffering force to the pressure seat 321. It is understood that when the position adjustment module 400 drives the pressure head 320 to the workpiece placement stage 200, the pressure seat 321 drives the cleaning belt 350, which abuts against the lower end of the adsorption member 322, to abut against the workpiece. The pressure seat 321 slides upwards on the first mounting base 310 in the vertical direction. The elastic buffer 323 provides a downward elastic force to the pressure seat 321 until the pressure seat 321 is in a state of force balance, preventing excessive force on the workpiece and potential damage when the pressure seat 321 moves downwards to abut against the adsorption member 322.

[0039] In a specific embodiment of this utility model, the pressure head 320 further includes a bolt 325, the bolt 325 extending vertically. A through hole is provided on the first mounting base 310, and the shank of the bolt 325 slidably passes through the through hole in the vertical direction. The bolt 325 is threadedly connected to the pressure seat 321, and the head of the bolt 325 can abut against the first mounting base 310 to limit the pressure seat 321 in the vertical direction. The elastic buffer 323 is a compression spring, which is sleeved on the bolt 325. It can be understood that the bolt 325 can guide the pressure seat 321 to move vertically; by sleeved on the bolt 325, the deformation of the compression spring in the horizontal direction can be reduced.

[0040] refer to Figure 1 In some embodiments of this utility model, the wiping module 300 further includes a pulling structure 360, which is disposed on the first mounting base 310 and located on the moving path of the cleaning belt 350. The pulling structure 360 ​​is used to pull the cleaning belt 350. It can be understood that when the wiped cleaning belt 350 on the take-up roller 340 reaches its maximum size, it is necessary to remove the cleaning belt roll from the take-up roller 340. At this time, by setting the pulling structure 360, the cleaning belt 350 can continue to move without pausing the operation of the wiping mechanism, further improving the wiping efficiency.

[0041] Understandably, the pulling structure 360 ​​moves the cleaning belt 350 a preset distance so that an unwiped segment of the cleaning belt moves below the pressure head 320. At this point, the pulling structure 360 ​​stops pulling the cleaning belt 350. After the unwiped segment has finished wiping the workpiece, the pulling structure 360 ​​again moves the wiped segment a preset distance so that the next unwiped segment is below the pressure head 320 for the next wiping cycle. The pulling structure 360 ​​allows for pulling the cleaning belt 350 at a fixed distance, ensuring that the length of the cleaning belt segment wiped is the same each time.

[0042] like Figure 4 and Figure 5As shown, in some embodiments, the material pulling structure 360 ​​includes a mounting frame 361, a material pulling roller assembly, and a drive structure 363. The material pulling roller assembly is mounted on the mounting frame 361 and located on the movement path of the cleaning belt 350. The drive structure 363 is driven by the material pulling roller 362 of the material pulling roller assembly via a gear set 364, and can drive the cleaning belt 350 to move via the material pulling roller 362. The drive structure 363 is driven by the take-up roller 340 via a transmission belt 365. The transmission ratio between the drive structure 363 and the material pulling roller 362 is greater than the transmission ratio between the drive structure 363 and the take-up roller 340. It is understood that because the transmission ratio between the drive structure 363 and the material pulling roller 362 is greater than the transmission ratio between the drive structure 363 and the take-up roller 340, the speed at which the material pulling structure 360 ​​pulls the cleaning belt 350 is slower than the speed at which the take-up roller 340 takes up the cleaning belt 350. Therefore, the take-up roller 340 takes up the cleaning belt 350 more tightly.

[0043] Specifically, the conveyor belt is a round belt. It is understood that by using a round belt to connect the drive structure 363 and the take-up roller 340, when the take-up roller 340 rotates faster than the pull roller 362, slippage will occur. This reduces the deviation between the take-up speed of the take-up roller 340 and the pull speed of the pull roller 362 on the cleaning belt 350, thereby ensuring that the cleaning belt 350 remains taut throughout its movement.

[0044] like Figure 4 As shown, in one embodiment of this utility model, the mounting frame 361 includes a first frame 361a and a second frame 361b. The first frame 361a is slidably mounted on the second frame 361b in the vertical direction, and the two pull rollers 362 of the pull roller assembly are respectively mounted on the first frame 361a and the second frame 361b. It can be understood that by sliding the first frame 361a in the vertical direction, the distance between the two pull rollers 362 on the pull roller assembly can be adjusted.

[0045] refer to Figure 5In some embodiments of this utility model, the position adjustment module 400 includes a horizontal adjustment structure 410 and a lifting structure 420 connected to each other. The horizontal adjustment structure 410 is used to adjust the position of the wiping module 300 in the first horizontal direction so that the pressure head 320 can reciprocate above the liquid storage tank 100 and the workpiece placement table 200. The lifting structure 420 is used to drive the wiping module 300 to perform lifting and lowering movements. It can be understood that the wiping module 300 is moved by the horizontal adjustment structure 410 so that the pressure head 320 is positioned above the liquid storage tank 100. Then, the wiping module 300 is lowered by the lifting structure 420 so that the cleaning belt 350, which abuts against the lower end of the pressure head 320, absorbs the cleaning fluid in the liquid storage tank 100. Then, the wiping module 300 is raised by the lifting structure 420. Then, the wiping module 300 is moved by the horizontal adjustment structure 410 so that the pressure head 320 is positioned directly above the first end of the workpiece on the workpiece placement table 200. Finally, the lifting structure... The wiping module 300 is driven to descend so that the cleaning belt 350, which abuts against the lower end of the pressure head 320, abuts against the first end of the workpiece. Then, the wiping module 300 is driven to move along the first horizontal direction through the horizontal adjustment structure 410 so that the cleaning belt 350, which abuts against the lower end of the pressure head 320, moves along the workpiece surface to the second end of the workpiece. Then, the wiping module 300 is driven to rise through the lifting structure 420 so that the cleaning belt 350, which abuts against the lower end of the pressure head 320, leaves the workpiece. Finally, the pressure head 320 is driven to move back to directly above the first end of the workpiece through the horizontal adjustment structure 410.

[0046] like Figure 1 and Figure 5 As shown, in some embodiments, the horizontal adjustment structure 410 includes a first driver 411, a slide rail 412, and a slide block 413. The slide block 413 is slidably disposed on the slide rail 412, which extends along a first horizontal direction. The first driver 411 is connected to the slide block 413 and is used to drive the slide block 413 to slide along the slide rail 412. A lifting structure 420 is disposed on the slide block 413 and is connected to the wiping module 300. A liquid storage tank 100 is disposed on the slide rail 412, and the liquid storage tank 100 and the workpiece placement platform 200 are spaced apart along the first horizontal direction. It is understood that the first driver 411 drives the slide 413 to move along the slide rail 412, thereby driving the lifting structure 420 on the slide 413 to move, which in turn drives the wiping module 300 connected to the lifting structure 420 to move, so that the pressure head 320 of the wiping module 300 moves in the first horizontal direction, thereby realizing the movement of the pressure head 320 above the liquid storage tank 100 and above the workpiece placement table 200.

[0047] Specifically, the first driver 411 is a horizontal adjustment motor.

[0048] refer to Figure 2 and Figure 5In some embodiments, the lifting structure 420 includes a second driver 421 and a second mounting base 422. The second driver 421 is mounted on the slide base 413 and connected to the second mounting base 422, and is used to drive the second mounting base 422 to perform lifting movements. The wiping module 300 is slidably mounted on the second mounting base 422 along a second horizontal direction, which is spaced at a certain angle from the first horizontal direction. It can be understood that by sliding the wiping module 300 along the second horizontal direction, the pressure head 320, the liquid storage tank 100, and the workpiece are distributed along the first horizontal direction. Then, the horizontal adjustment structure 410 drives the pressure head 320 to move along the first horizontal direction so that the pressure head 320 can be positioned directly above the workpiece on the liquid storage tank 100 or the workpiece placement platform 200.

[0049] Understandably, when the cleaning belt segment below the pressure head 320 is soaked in cleaning fluid, the first driver 411 drives the slide 413 to slide along the first horizontal direction so that the pressure head 320 of the wiping module 300 is directly above the first end of the workpiece. Then, the second driver 421 drives the second mounting base 422 to move down, thereby moving the pressure head 320 down so that the cleaning belt 350 on the lower side of the pressure head 320 abuts against the first end of the workpiece. Then, the first driver 411 drives the slide 413 to slide along the first horizontal direction so that the cleaning belt 350 abutting against the lower end of the pressure head 320 moves along the workpiece surface to the second end of the workpiece. Then, the second driver 421 drives the pressure head 320 to rise so that the cleaning belt 350 is detached from the workpiece. Finally, the first driver 411 drives the pressure head 320 to move back to directly above the first end of the workpiece.

[0050] Specifically, the second actuator 421 is a lifting cylinder, with the first horizontal direction and the second horizontal direction spaced 90° apart.

[0051] like Figure 2 As shown, in one embodiment, the first mounting base 310 is provided with an elongated hole 311 extending along a second horizontal direction. A threaded locking member 312 is slidably inserted into the elongated hole 311, and the threaded locking member 312 is threadedly connected to the second mounting base 422. It can be understood that when the wiping module 300 slides along the second horizontal direction, and the pressure head 320 is facing the liquid storage tank 100 or the workpiece on the workpiece placement platform 200, the threaded locking member 312 is screwed on so that the head of the threaded locking member 312 abuts against the first mounting base 310. Continuing to screw on the threaded locking member 312 reduces the distance between the first mounting base 310 and the second mounting base 422, thereby increasing the friction between the first mounting base 310 and the second mounting base 422 to prevent the first mounting base 310 from sliding relative to the second mounting base 422.

[0052] refer to Figure 2 and Figure 3In a further embodiment of this utility model, the wiping module 300 further includes two guide rollers 370, which are distributed on both sides of the pressure head 320 and are used to guide the conveying of the cleaning belt 350. Each guide roller 370 is provided with two limiting members 371. It can be understood that by providing two limiting members 371 at intervals on the guide rollers 370, the movement path of the cleaning belt 350 is restricted to ensure that the cleaning belt 350 can be aligned with the pressure head 320.

[0053] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
