Description

Technical Field

[0001] This invention belongs to the technical field of battery cell processing equipment, specifically relating to a cleaning device for the take-up and pulling belt of a fully automatic winding machine. Background Technology

[0002] In the production process of lithium batteries, the positive and negative electrode sheets are first wound into a cell, then the cell is placed into a casing, electrolyte is injected into the casing, and finally the casing is sealed. During the actual winding process, the electrode sheets come into contact with and rub against the guide rail base plate and guide rail during movement, generating electrode detachment particles such as positive and negative electrode active material particles, copper shavings, and aluminum shavings. These detached electrode detachment particles will be rolled into the entire cell along with the electrode sheets, causing defects such as surface protrusions, self-discharge, and short circuits, posing safety hazards to lithium batteries. Therefore, rubber rollers are usually installed along the cell's path to adhere to the particles.

[0003] When the rubber belt of the rubber roller reaches its limit, it needs to be replaced. In the existing technology, the rubber roller is generally fixed to the frame with bolts, and the position of the rubber roller needs to be adjusted according to the thickness of the battery cell. This makes the installation process of the rubber roller inconvenient and the position of the rubber belt cannot be adjusted quickly. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning device for the take-up belt of a fully automatic winding machine, so as to solve the problem that the rubber roller needs to be replaced when the rubber belt reaches its limit. In the prior art, the rubber roller is generally fixed to the frame with bolts, and the position of the rubber roller needs to be adjusted according to the thickness of the battery cell. This makes the installation process of the rubber roller inconvenient and the position of the rubber belt cannot be adjusted quickly.

[0005] A cleaning device for the take-up belt of a fully automatic winding machine includes a frame, a cleaning mechanism, and a take-up mechanism. The cleaning mechanism and the take-up mechanism are arranged inside the frame, and the belt passes through the cleaning mechanism and the take-up mechanism in sequence. The air bladder of the air bladder assembly of the cleaning mechanism pushes the belt to squeeze the upper and lower surfaces of the belt to adhere particles, and the air bladder fixes the cleaning roller. The take-up mechanism winds the belt after the particles have adhered.

[0006] Preferably, the cleaning mechanism includes an upper drive roller and a lower drive roller. A pull belt passes laterally through the inside of the frame. The upper drive roller and the lower drive roller are respectively located above and below the pull belt. Cleaning rubber rollers are sleeved on the outside of the upper drive roller and the lower drive roller, and the ends of the rubber strips of the two cleaning rubber rollers are respectively attached to the receiving mechanism. The receiving mechanism rotates the cleaning rubber rollers by pulling the rubber strip. An airbag assembly is provided between the upper drive roller and the lower drive roller and the receiving mechanism. After the airbag of the airbag assembly is inflated, the upper drive roller and the lower drive roller are fixed to the frame, and the airbag is squeezed on the upper and lower sides of the rubber strip so that it is tightly attached to the upper and lower surfaces of the pull belt.

[0007] Preferably, the airbag assembly includes an airbag, an inflation tube, a sliding plate, a spring, and a plug. The airbag is provided above and below the pull strap. Sliding plates are slidably connected between the two sides of the frame, and sliding plates are provided above and below the pull strap. The sliding plates correspond one-to-one with the airbags. The plug is provided on the side of the two sliding plates near the upper and lower drive rollers. The upper and lower drive rollers are provided with insertion holes corresponding to the plugs. One side of the airbag is in contact with the sliding plate, and the other side of the airbag is provided with an L-shaped baffle. An inflation tube is provided on the outside of the frame, and the inflation tube is connected to the airbag.

[0008] Preferably, both the upper drive roller and the lower drive roller include a fixed block and a rotating shaft. The two ends of the rotating shaft are symmetrically fixedly connected to the fixed blocks. The frame is provided with a fixing hole corresponding to the fixed block. The fixed block has a transverse insertion hole corresponding to the insertion rod. Both the fixed block and the fixing hole have a cross-shaped structure.

[0009] Preferably, the inner walls on both sides of the frame are provided with sliding grooves, the two ends of the slide plate are symmetrically provided with sliding blocks and the sliding blocks are slidably connected to the sliding grooves, and the spring is fixedly connected between the end of the sliding groove and the sliding block.

[0010] Preferably, the receiving mechanism includes an upper receiving roller and a lower receiving roller, which are rotatably connected between the two sides of the frame. A drive assembly is provided outside the frame, and the drive assembly drives the upper receiving roller and the lower receiving roller to rotate. An energizer switch for the drive assembly is provided above the frame, and the upper receiving roller is located on one side of the energizer switch. The drive assembly is electrically connected to the energizer switch via a wire.

[0011] Preferably, the drive assembly includes a drive motor, a drive gear, a driven gear one, and a driven gear two. The drive motor is fixedly connected to one side of the frame, and the output shaft of the drive motor is fixedly connected to the drive gear. The driven gear one and the driven gear two are respectively meshed on both sides of the drive gear. The driven gear one and the driven gear two are respectively sleeved on the outer sides of the upper take-up roller and the lower take-up roller.

[0012] The present invention has the following advantages:

[0013] This invention places a pull belt between the upper and lower drive rollers. Both the upper and lower drive rollers are equipped with cleaning rubber rollers 26. One end of the adhesive tape on the cleaning rubber rollers is adhered to a take-up mechanism. As the take-up mechanism rotates, the tape is pulled out, allowing the adhesive side of the tape to contact the pull belt, thus adhering to particles. The airbag assembly inflates, pushing a sliding plate towards the upper and lower drive rollers. This allows the inserts on both sides of the sliding plate to be inserted into the insertion holes, securing the upper and lower drive rollers. The downward expansion of the airbag pushes the tape downwards, allowing it to contact the pull belt. As the pull belt and tape move, particles on the upper and lower surfaces of the pull belt adhere. The inflation degree of the airbag can be adjusted by changing the gas flow rate, allowing the airbag to adapt to electric pull belts of different thicknesses, thus broadening its applicability. This invention uses an airbag assembly to fix the cleaning rubber rollers and can use the airbag to compress the tape, causing the tape to adhere to particles of different heights on the surface of the battery cells.

[0023] The following detailed description of the embodiments, with reference to the accompanying drawings, will further illustrate the specific implementation of the present invention, in order to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of the present invention.

[0024] like Figure 1-4 The illustrated cleaning device for the take-up belt of a fully automatic winding machine includes a frame 1, a cleaning mechanism 2, and a take-up mechanism 4. The cleaning mechanism 2 and the take-up mechanism 4 are located inside the frame 1, and the pull belt 10 passes through the cleaning mechanism 2 and the take-up mechanism 4 in sequence. The airbag 30 of the airbag assembly 3 of the cleaning mechanism 2 pushes the tape 27 to press against the upper and lower surfaces of the pull belt 10 to adhere particles, and the airbag fixes the cleaning roller 26. The take-up mechanism 4 winds the tape 27 after the particles have adhered.

[0025] The cleaning mechanism 2 includes an upper drive roller 20 and a lower drive roller 21. A pull belt 10 passes through the interior of the frame 1 laterally. The upper drive roller 20 and the lower drive roller 21 are respectively located above and below the pull belt 10. Cleaning rubber rollers 26 are sleeved on the outside of the upper drive roller 20 and the lower drive roller 21, and the ends of the tape 27 of the two cleaning rubber rollers 26 are respectively attached to the receiving mechanism 4. The receiving mechanism 4 rotates the cleaning rubber rollers 26 by pulling the tape 27. An airbag assembly 3 is provided between the upper drive roller 20 and the lower drive roller 21 and the receiving mechanism 4. After the airbag 30 of the airbag assembly 3 is inflated, the upper drive roller 20 and the lower drive roller 21 are fixed to the frame 1, and the airbag 30 is pressed against the upper and lower sides of the tape 27 so that it is tightly attached to the upper and lower surfaces of the pull belt 10. The airbag assembly 3 includes an airbag 30, an inflation pipe 31, a slide plate 32, a spring 37, and a rod 33. The airbag 30 is provided above and below the pull strap 10. The slide plates 32 are slidably connected between the two sides of the frame 1, and the slide plates 32 are provided above and below the pull strap 10. The slide plates 32 correspond one-to-one with the airbag 30. The rod 33 is provided on the side of the two slide plates 32 near the upper drive roller 20 and the lower drive roller 21. The upper drive roller 20 and the lower drive roller 21 are provided with insertion holes 24 corresponding to the rod 33. One side of the airbag 30 is in contact with the slide plate 32, and the other side of the airbag 30 is provided with an L-shaped baffle 36. The inflation pipe 31 is provided on the outside of the frame 1 and the inflation pipe 31 is connected to the airbag 30.

[0026] The pull belt 10 is located between the upper drive roller 20 and the lower drive roller 21. Both the upper drive roller 20 and the lower drive roller 21 are equipped with cleaning rollers 26. One end of the adhesive tape 27 on the cleaning roller 26 is adhered to the receiving mechanism 4. As the receiving mechanism 4 rotates, the adhesive tape 27 is pulled out, allowing the adhesive side of the tape 27 to contact the pull belt 10, thus achieving the effect of adhering particulate matter. To ensure that the tape 27 can contact the pull belt, an airbag assembly 3 is provided between the upper drive roller 20, the lower drive roller 21, and the receiving mechanism 4. An inflation pipe 31 is connected to an external air pump, supplying gas to the airbag 30. After inflation, the airbag 30 expands. An L-shaped baffle 36 is provided on one side, so the airbag 30 can only expand towards and below the slide plate 32, pushing the slide plate 32 upwards. The drive roller 20 and the lower drive roller 21 move in the same direction, so that the insert rods 33 on both sides of the slide plate 32 can be inserted into the insertion holes 24. This allows the insert rods 33 to fix the upper drive roller 20 and the lower drive roller 21, preventing them from sliding out of the frame 1. The cleaning roller 26 above the upper drive roller 20 and the lower drive roller 21 is more stable during movement. The downward expansion of the airbag 30 pushes the tape 27 downward, allowing the tape 27 to contact the pull belt 10. As the pull belt 10 and the tape 27 move, particles on the upper and lower surfaces of the pull belt 10 can be adhered. Furthermore, the expansion degree of the airbag 30 can be adjusted by changing the gas delivery rate, thus allowing the airbag 30 to adapt to electric pull belts of different thicknesses, making it more versatile.

[0027] Both the upper drive roller 20 and the lower drive roller 21 include a fixed block 23 and a rotating shaft 22. The two ends of the rotating shaft 22 are symmetrically fixedly connected to the fixed blocks 23. The frame 1 is provided with a fixing hole 25 corresponding to the fixed block 23. The fixed block 23 has a transverse insertion hole 24 corresponding to the insertion rod 33. Both the fixed block 23 and the fixing hole 25 are cross-shaped structures.

[0028] The fixing blocks 23 at both ends of the rotating shaft 22 pass through the fixing holes 25 on both sides of the frame 1. Since the fixing blocks 23 and the fixing holes 25 are both cross-shaped, the rotation of the fixing blocks 23 can be avoided. In order to prevent the fixing blocks 23 from sliding out of the frame 1, the insert rod 33 is used to correspond with the insert hole 24, thus fixing the fixing blocks 23. The limitation of the insert rod 33 can also limit the movement distance of the cleaning roller 26, preventing it from moving too far back and forth on the rotating shaft 22, so that the tape 27 can move smoothly.

[0029] The inner walls on both sides of the frame 1 are provided with sliding grooves 34. The two ends of the slide plate 32 are symmetrically provided with sliding blocks 35 and the sliding blocks 35 are slidably connected to the sliding grooves 34. The spring 37 is fixedly connected between the end of the sliding groove 34 and the sliding block 35.

[0030] The spring 37 is there so that the slide plate 32 can be reset. When the cleaning roller 26 needs to be replaced, the air bag 30 is deflated and the spring 37 releases energy, which can then drive the slide plate 32 and the insertion rod 33 away from the fixed block 23. In this way, the upper drive roller 20 and the lower drive roller 21 can be pulled out from the frame 1. After the new cleaning roller 26 is replaced, the air bag 30 can be re-inflated, which will then allow the insertion rod 33 to be inserted into the insertion hole 24. The spring 37 will recharge. This process is repeated, making it more convenient to replace the cleaning roller 26.

[0031] The receiving mechanism 4 includes an upper receiving roller 40 and a lower receiving roller 41, which are rotatably connected between the two sides of the frame 1. A drive assembly is provided outside the frame 1, and the drive assembly drives the upper receiving roller 40 and the lower receiving roller 41 to rotate. An energizer switch 42 of the drive assembly is provided above the frame 1. The upper receiving roller 40 is located on one side of the energizer switch 42. The drive assembly is electrically connected to the energizer switch 42 through a wire.

[0032] The receiving mechanism 4 uses used tape 27. After the tape 27 adheres to particles, it can be wound onto the upper receiving roller 40 and the lower receiving roller 41. As the cleaning time increases, the thickness of the tape 27 wound on the upper receiving roller 40 and the lower receiving roller 41 gradually increases. The tape 27 on the upper receiving roller 40 will slowly thicken until it squeezes the power switch 42. When the power switch 42 is pressed, it indicates that the tape 27 wound on the upper receiving roller 40 and the lower receiving roller 41 has reached its maximum limit, and the drive component can stop operating. This also allows the upper receiving roller 40 and the lower receiving roller 41 to be replaced.

[0033] The drive assembly includes a drive motor 43, a drive gear 44, a driven gear 1 45, and a driven gear 2 46. The drive motor 43 is fixedly connected to one side of the frame 1, and the output shaft of the drive motor 43 is fixedly connected to the drive gear 44. The driven gear 1 45 and the driven gear 2 46 are respectively meshed on both sides of the drive gear 44. The driven gear 1 45 and the driven gear 2 46 are respectively sleeved on the outside of the upper take-up roller 40 and the lower take-up roller 41.

[0034] The drive motor 43 can simultaneously drive the upper take-up roller 40 and the lower take-up roller 41 to rotate using the drive gear 44, driven gear 1 45 and driven gear 2 46, thereby simultaneously winding up the tape 27 on the upper and lower sides of the pull belt 10.

[0035] Working principle: The pull belt 10 is located between the upper drive roller 20 and the lower drive roller 21. Cleaning rollers 26 are provided on the surfaces of both the upper and lower drive rollers 20 and 21. One end of the adhesive tape 27 on the cleaning rollers 26 is adhered to the receiving mechanism 4. As the receiving mechanism 4 rotates, the tape 27 is pulled out, causing the adhesive side of the tape 27 to contact the pull belt 10, thus achieving the effect of adhering particulate matter. To ensure that the tape 27 can contact the pull belt, an airbag assembly 3 is provided between the upper drive roller 20, the lower drive roller 21, and the receiving mechanism 4. The air pipe 31 is connected to an external air pump, which delivers gas to the airbag 30. After inflation, the airbag 30 expands. An L-shaped baffle 36 is provided on one side, so the airbag 30 can only expand towards and below the slide plate 32. After expansion, it pushes the slide plate 32 towards the upper drive roller 20 and the lower drive roller 21. This allows the insert rods 33 on both sides of the slide plate 32 to be inserted into the insertion holes 24. The insert rods 33 can then be used to fix the upper drive roller 20 and the lower drive roller 21, preventing them from sliding out of the frame 1. The cleaning roller 26 above moves more stably, and the downward expansion of the airbag 30 pushes the tape 27 downward, allowing the tape 27 to contact the pull belt 10. As the pull belt 10 and tape 27 move, particles on the upper and lower surfaces of the pull belt 10 can be adhered. The expansion degree of the airbag 30 can be adjusted by changing the gas delivery rate, thus allowing the airbag 30 to adapt to electric pull belts of different thicknesses, making it more versatile. The receiving mechanism 4 uses the used tape 27, which has adhered to particles. Subsequently, as the upper take-up roller 40 and the lower take-up roller 41 are wound on the upper take-up roller 40 and the lower take-up roller 41, and as the cleaning time increases, the thickness of the tape 27 wound on the upper take-up roller 40 and the lower take-up roller 41 gradually increases. The tape 27 on the upper take-up roller 40 will slowly thicken until it squeezes the power switch 42. When the power switch 42 is pressed, it indicates that the tape 27 wound on the upper take-up roller 40 and the lower take-up roller 41 has reached its maximum limit, and the drive assembly can stop operating. This also allows the upper take-up roller 40 and the lower take-up roller 41 to be replaced.
