Abstract

This application proposes a waste removal device, including a mounting plate and a suction module on the top of the mounting plate, a roller clamping module and an air blowing module on the bottom of the mounting plate. The roller clamping module includes a roller clamping drive mechanism, a mounting frame and two moving rollers on the mounting frame. The axial direction of the moving rollers is set along the conveying direction of the product to be removed. The roller clamping drive mechanism drives the two moving rollers to rotate in a direction away from each other. The outer periphery of the moving rollers has a roller clamping surface and a cutting surface. When the product to be removed is located below the waste removal device, the air blowing module blows away the waste filaments below the roller clamping module. The two moving rollers rotate until the cutting surfaces face each other, forming a first channel that communicates with the suction module. The suction module sucks up the waste filaments, thereby removing them. Subsequently, the two moving rollers rotate until the roller clamping surfaces face each other, forming a gap for clamping the waste filaments. The moving rollers rotate upwards to clamp the waste filaments that have not been removed in the gap, causing the waste filaments to detach from the carrier plate and be sucked away by the suction module. This method has high waste removal efficiency and good waste removal effect.

Description

Technical Field

[0001] This application belongs to the field of photovoltaic module manufacturing technology, specifically, it relates to a waste removal device. Background Technology

[0002] In some photovoltaic module manufacturing processes, a conductive layer (such as copper foil) is adsorbed and fixed onto a movable carrier plate. The conductive pattern and waste wires are then formed by laser cutting. The conductive pattern is adsorbed and fixed onto the carrier plate, while the waste wires are not. Subsequently, the waste wires need to be removed from the carrier plate so that EVA and a backsheet can be directly attached to the conductive pattern.

[0003] Because the laser cutting path is relatively dense during the laser cutting of the conductive layer, the waste wires formed after laser cutting are relatively thin. These waste wires are easy to embed into the cutting grooves on the carrier plate below. In addition, during the laser cutting process, there may be insufficient cutting, resulting in the conductive pattern and the waste wires being connected. As a result, existing waste removal devices are prone to pulling and damaging the conductive pattern during the removal of waste wires, affecting the yield of the conductive pattern and resulting in low waste removal efficiency, which leads to low production efficiency of photovoltaic modules. Utility Model Content

[0004] In view of this, this application provides a waste removal device with high waste removal efficiency and low risk of damaging the conductive pattern during the process of removing waste wires.

[0007] The outer periphery of the moving roller has a roller clamping surface and a cutting surface, and the two ends of the roller clamping surface and the two ends of the cutting surface are connected to each other.

[0008] When the product to be removed is located below the waste removal device, the air blowing module blows away the waste filaments below the roller clamping module. The two moving rollers rotate until their tangential surfaces face each other, forming a first channel that connects with the suction module. The suction module then sucks up the waste filaments. The two moving rollers continue to rotate until their clamping surfaces face each other, forming a gap that pulls the waste filaments. The moving rollers rotate upwards to pull the waste filaments within the gap, and the suction module sucks up the pulled waste filaments.

During the rotation of the moving roller, there is always a gap between the cutter and the roller clamping surface opposite it.

[0010] After the two moving rollers rotate until their clamping surfaces face each other and clamp the waste wire upwards, the two moving rollers continue to rotate. When the cutting blade is located in the gap, the cutting blade cuts the waste wire in the gap. After cutting, the waste wire above the gap is sucked away by the suction module.

The nozzles face the roller clamp modules and are inclined downwards.

[0020] Compressed air enters the ventilation pipe through the air pipe connector and is then sprayed out through the nozzle onto the waste products to be removed below the roller clamp module.

[0021] Preferably, both ends of the vent pipe are provided with a first connector and a second connector.

[0022] Preferably, the mounting frame has a cavity inside to accommodate the moving roller, and both the top and bottom have openings communicating with the cavity;

[0023] In the same plane, perpendicular to the direction of conveying the waste product to be removed, each side of the mounting frame is provided with a movable roller, and the roller shafts of the movable rollers are fitted with bearings at both ends. The bearings are mounted on the mounting frame by locking blocks.

[0024] Preferably, one end of the roller is further fitted with a collar, a gear mounting component, and a gear in sequence on the outside of the bearing. The gear mounting component is locked in the radial direction of the roller. The collar is held between the bearing and the gear mounting component.

The gear is locked in the axial direction of the roller by the retaining ring and the collar. The gears at the ends of the two moving rollers in each roller clamping module are meshed.

[0025] The roller clamp drive mechanism includes a power output component, a synchronous pulley, and a synchronous belt. The power output component is mounted on a mounting plate. In each roller clamp module, the other end of the roller shaft of one of the moving rollers is fixedly mounted with a synchronous pulley on the outside of the bearing.

[0026] Preferably, a cutting blade is provided at the rear end of the roller clamping surface near the cutting surface along the direction of rotation of the moving roller equipped with a synchronous pulley.

[0027] Preferably, along the conveying direction of the waste product, the front and rear side walls of the mounting frame are provided with adjustment grooves that penetrate the mounting frame and communicate with the cavity.

[0028] The adjustment groove includes a first adjustment groove and a second adjustment groove arranged vertically, and a third adjustment groove and a fourth adjustment groove arranged horizontally. The first adjustment groove is located between two moving rollers.

One end of the through hole is connected to the second adjustment groove. An elastic element is provided in the through hole. One end of the elastic element passes through the second adjustment groove and abuts against the mounting frame. An adjustment element is inserted into the through hole. One end of the adjustment element can abut against the other end of the elastic element. By turning the other end of the adjustment element, the elastic deformation of the elastic element can be changed to change the width of the first adjustment groove, thereby adjusting the distance between the two moving rollers on the mounting frame.

[0030] Preferably, the suction module includes an air duct and multiple connecting pipes disposed at the bottom of the air duct and connected to the air duct. The number of connecting pipes is the same as the number of roller clamp modules and is set in a one-to-one correspondence. The end of the connecting pipe away from the air duct is mounted on the mounting plate.

[0031] The two moving rollers in the roller clamp module rotate to form a first channel with opposite tangential surfaces, which is connected to the connecting pipe above it.

[0032] Preferably, one end of the air duct is provided with an air extraction port and the other end is provided with an observation port. The observation port is sealed by a sealing plate, and a sealing gasket is provided between the observation port and the sealing plate.

The top of the mounting frame is connected to the bottom of the mounting plate, and the bottom of the mounting frame is connected to the lower cover.

[0036] The beneficial effects of this application are as follows: the air blowing module disperses the waste filaments below the roller clamping module, the two moving rollers in the roller clamping module rotate to face each other, forming a first channel that connects with the suction module, the suction module sucks the waste filaments into the suction module through the first channel, thereby removing the waste filaments, and then the two moving rollers in the roller clamping module rotate to face each other to form a gap for clamping the waste filaments, the two moving rollers rotate and, with the cooperation of the two roller clamping surfaces, clamp the waste filaments that have not been removed in the gap, so that the waste filaments are detached from the carrier plate and are sucked away by the suction module, which has a high waste removal efficiency and a good waste removal effect.

[0037] Furthermore, if some waste wires remain attached to the carrier plate after the two roller clamping surfaces work together to pull the waste wires, a cutter located near the cutting surface at the rear end of the roller clamping surface of one of the moving rollers along its rotation direction can cut the waste wires in the gap. After cutting, the waste wires above the gap are drawn away by the suction module, while the waste wires below the gap can be processed after all the waste wires in the entire product to be de-wasted are removed. This avoids the roller clamping module from excessively pulling the waste wires, which could damage the conductive pattern. Attached Figure Description

Detailed Implementation

[0050] The embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0051] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] This application provides a waste removal device, referenced Figure 1-9 It includes a mounting plate 1, a suction module 2 disposed on the top of the mounting plate 1, a roller clamp module 3 disposed on the bottom of the mounting plate 1, and an air blowing module 4.

[0053] The roller clamp module 3 includes a roller clamp drive mechanism, a mounting frame 31, and two movable rollers 32 mounted on the mounting frame 31. The axial direction of the movable rollers 32 is set along the conveying direction of the waste product to be removed. The roller clamp drive mechanism drives the two movable rollers 32 to rotate in a direction away from each other.

[0054] The outer periphery of the moving roller 32 has a roller clamping surface 321 and a cutting surface 322, and the two ends of the roller clamping surface 321 and the two ends of the cutting surface 322 are connected to each other;

[0055] When the product to be removed is located below the waste removal device, the air blowing module 4 blows away the waste filaments below the roller clamping module 3. The two moving rollers 32 rotate until the cut surfaces 322 face each other, forming a first channel that connects with the suction module 2. The suction module 2 sucks up the waste filaments. The two moving rollers 32 continue to rotate until the roller clamping surfaces 321 face each other, forming a gap for clamping the waste filaments. The moving rollers 32 rotate upward to clamp the waste filaments in the gap, and the suction module 2 sucks up the clamped waste filaments.

[0056] In a preferred embodiment, the waste product to be removed is a conductive layer after laser cutting, which includes the conductive pattern that needs to be retained and is fixed on the carrier plate, and the waste filaments that are not adsorbed on the carrier plate and need to be removed.

[0057] like Figure 6 As shown, the roller clamping surface 321 of the moving roller 32 is arc-shaped, and the tangent surface 322 is straight. The two ends of the roller clamping surface 321 are connected to the two ends of the tangent surface 322.

[0058] After laser cutting, the waste product to be removed is conveyed to the bottom of the waste removal device via a carrier plate. The air blowing module 4 is activated to blow away the waste wires below the roller clamp module 3 and blow out the waste wires embedded in the cutting groove of the carrier plate so that the subsequent suction module 2 can suck up the waste wires.

[0059] The roller clamp drive mechanism drives the two moving rollers 32 in a direction away from each other. Figure 6 (In the direction indicated by the middle arrow) rotate. During the rotation, the two moving rollers 32 first rotate until the tangent surface 322 is opposite to each other to form a first channel. The first channel is connected to the suction module 2. The suction module 2 sucks up the waste filaments below the roller clamp module 3. Under the action of the suction module 2, the waste filaments are separated from the carrier plate and enter the first channel, and then are sucked away by the suction module 2. During this process, some waste wires may remain in the first channel (because insufficient laser cutting causes the waste wires to be connected to the conductive pattern, or the waste wires are stuck in the cutting groove of the carrier plate) and not be removed by the suction module 2. In this embodiment, the two moving rollers 32 continue to rotate until the roller clamping surfaces 321 face each other, forming a gap for clamping the waste wires. When the two moving rollers 32 rotate until the roller clamping surfaces 321 face each other, the waste wires are clamped between the two roller clamping surfaces 321, that is, in the gap formed by the two roller clamping surfaces 321. The two moving rollers 32 continue to rotate to generate an upward force to clamp the waste wires, so that the waste wires are separated from the carrier plate (separated from the conductive pattern or removed from the cutting groove) and are removed by the suction module 2 above the roller clamping module 3.

[0060] The combination of blowing, suction, and roller clamping in this embodiment can effectively remove waste wires from the carrier plate after laser cutting, resulting in high waste removal efficiency and waste wire removal rate.

[0061] During the waste removal process, the air blowing module 4, the roller clamping module 3, and the suction module 2 can be activated simultaneously, working together to remove the waste fibers below. Alternatively, the air blowing module 4 can be activated first to disperse the waste fibers, followed by the activation of the roller clamping module 3 and the suction module 2. In this embodiment, there is no specific limitation on the activation order of the air blowing module 4, the roller clamping module 3, and the suction module 2, as long as the waste fibers can be effectively removed through their cooperation.

[0062] It is understandable that during the rotation of the two moving rollers 32 in the roller clamp module 3, the suction module is always in the start state, thus continuously sucking up waste filaments during the waste removal process.

[0063] After the roller clamp module 3 pulls out the waste wire, there may still be a small number of waste wires connected to the conductive pattern (due to the influence of the laser cutting process). If the waste wire is pulled upwards again by the roller clamp module 3, it may cause the conductive pattern to be pulled while pulling out the waste wire, resulting in damage to the conductive pattern.

[0064] Therefore, in a further preferred embodiment of the present application, one of the moving rollers 32 in the roller clamping module 3 is provided with a cutter 323 near the cutting surface 322 at the rear end of its roller clamping surface 321 along its rotation direction. During the rotation of the moving roller 32, there is always a gap between the cutter 323 and its opposite roller clamping surface 321.

[0065] After the two moving rollers 32 rotate to face each other on the roller clamping surface 321 and clamp the waste wire upwards, the two moving rollers 32 continue to rotate. When the cutting blade 323 is located in the gap, the cutting blade 323 cuts the waste wire in the gap. After cutting, the waste wire located above the gap is drawn away by the suction module 2.

[0066] After the roller clamping module 3 clamps and pulls the waste wire, the waste wire that has detached from the carrier plate is drawn away by the suction module 2. The waste wire that has not yet detached from the carrier plate is in the gap formed by the two roller clamping surfaces 321. The two moving rollers 32 continue to rotate until the cutter 323 reaches the gap. Under the action of the rotation of the moving rollers 32, the cutter 323 can cut the waste wire in the gap. After cutting, the waste wire above the gap is drawn away by the suction module 2, while the waste wire below the gap remains on the carrier plate.

[0067] During this process, a small gap exists between the cutter 323 and its opposite roller clamping surface 321, ensuring that the cutter 323 does not come into contact with its opposite roller clamping surface 321 during the cutting of waste wire, thereby preventing the cutter 323 from damaging the roller clamping surface 321. This embodiment does not specifically limit the gap between the cutter 323 and the roller clamping surface 321, as long as it ensures that the cutter 323 does not come into contact with its opposite roller clamping surface 321 during the cutting of waste wire, and that the cutter 323 can cut the waste wire within the gap under the rotation of the moving roller 32.

[0068] Waste wire located below the gap after cutting can be removed from the carrier plate manually or by other mechanical means after the waste removal process is completed.

[0069] It is understandable that after removing waste filaments from the carrier plate through the combined blowing, suction, and roller clamping methods of this embodiment, only a small portion of the waste filaments are cut off by the cutter 323, or even all of the waste filaments are removed, leaving no waste filaments to be cut. Therefore, only a small portion of the waste filaments needs to be removed manually or by other mechanical means, which will not have a significant impact on the production cycle and has a high waste removal efficiency. In addition, the design of the cutter 323 can prevent the roller clamping module 3 from excessively pulling the waste filaments and damaging the conductive pattern, resulting in a high yield of conductive patterns after waste removal.

[0070] In a preferred embodiment, refer to Figure 1 Along the length of the mounting plate ( Figure 1 In the y-direction), both ends of the mounting plate 1 are equipped with drive modules 5, and the length direction of the mounting plate is perpendicular to the conveying direction of the waste product to be removed in the same plane.

[0071] Drive module 5 includes a first drive mechanism 51 and a lifting drive mechanism 52. The lifting drive mechanism 52 is mounted on the first drive mechanism 51. The mounting plate 1 is connected to the lifting drive mechanism 52. The first drive mechanism 51 drives the lifting drive mechanism 52 along the conveying direction of the waste product to be removed. Figure 1 The lifting drive mechanism 52 drives the mounting plate 1 to move (i.e., along the x-direction) and lift (i.e., along the x-direction). Figure 1 (Moves up and down in the z-direction).

[0072] Since the suction module 2, the roller clamp module 3 and the air blowing module 4 (hereinafter referred to as the waste filament removal unit) are all installed on the mounting plate 1, the first drive mechanism 51 drives the lifting drive mechanism 52 to move along the x direction, so as to drive the waste filament removal unit to move in the x direction. The lifting drive mechanism 52 drives the mounting plate 1 to lift, so as to drive the waste filament removal unit to lift.

[0073] The lifting drive mechanism 52 in this embodiment can adjust the height of the waste filament removal unit to adapt to products of different thicknesses. The position of the waste filament removal unit in the height direction can be adjusted according to the waste removal effect. The first drive mechanism 51 can adjust the position of the waste filament removal unit in the x direction to ensure that the waste filament removal unit is located above the area of ​​the product to be de-wasted.

[0074] In a further preferred embodiment, continue to refer to Figure 1 In the y direction, both ends of the mounting plate 1 are provided with connecting plates 11, and the connecting plates 11 are set on the corresponding lifting drive mechanism 52.

[0075] One end of the mounting plate 1 is provided with a slider 12, and the connecting plate 11 at this end is provided with a slide rail 13 along the length direction of the mounting plate 1. The slider 12 is slidably connected to the slide rail 13.

[0076] The connecting plate 11 at the other end is provided with a second driving mechanism 14. The second driving mechanism 14 drives the mounting plate 1 to move back and forth in the length direction of the mounting plate 1, so that the slider 12 slides back and forth on the slide rail 13 for guidance.

[0077] During the waste removal process, the second drive mechanism 14 can be continuously activated, causing the waste filament removal unit to move back and forth in the y direction. Alternatively, the second drive mechanism 14 can be activated in stages, causing the waste filament removal unit to move back and forth in the y direction in stages, so as to ensure that the waste filaments of the product to be removed can be effectively removed across the entire width in the y direction, ensuring that there are no dead corners in the removal process.

[0078] In one specific embodiment, the second drive mechanism 14 can be a cylinder. The power output end of the cylinder is connected to the end of the mounting plate 1 away from the slider 12. The cylinder directly drives the mounting plate 1 to move back and forth in the y direction. During the movement, the slider 12 slides back and forth on the slide rail 13 for guidance.

[0079] In another specific implementation, such as Figure 1 As shown, the second drive mechanism 14 includes a movable drive component 141, a first rocker arm 142, and a second rocker arm 143. The movable drive component 141 is mounted on the connecting plate 11. The power output end of the movable drive component 141 is fixedly connected to one end of the first rocker arm 142. The other end of the first rocker arm 142 is movably connected to one end of the second rocker arm 143. The other end of the second rocker arm 143 is movably connected to the mounting plate 1. The movable drive component 141 drives the first rocker arm 142 to rotate.

[0080] The moving drive component 141 can be a motor. The motor drives the first rocker arm 142 to rotate, which in turn drives the second rocker arm 143 to rotate, thereby causing the mounting plate 1, which is movably connected to the second rocker arm 143, to move in the y direction.

[0081] Typically, the conductive layer in laser-cut products is relatively large, and the area requiring waste removal is also large. To improve waste removal efficiency and shorten removal time, refer to... Figure 2 In this embodiment, multiple roller clamp modules 3 are provided at the bottom of the mounting plate 1. The following descriptions will use the example of providing multiple roller clamp modules 3 at the bottom of the mounting plate 1 to further illustrate this embodiment.

[0082] Preferably, multiple roller clamp modules 3 are spaced apart along the y-direction.

[0083] During waste removal, the product to be removed can be divided into multiple waste removal areas along the x-direction. Along the x-direction, when the first waste removal area of ​​the product is conveyed to the bottom of the waste filament removal unit, the waste filament removal unit, in conjunction with the first drive mechanism 51 and the second drive mechanism 14, removes the waste filaments from that area. Then, the product continues to move along the x-direction, so that the second waste removal area is conveyed to the bottom of the waste filament removal unit, until all the waste filaments of the entire product are removed.

[0084] In a preferred embodiment, along the conveying direction of the waste product to be removed, air blowing modules 4 are provided on both sides of the bottom of the mounting plate 1, and each roller clamp module 3 is located between two air blowing modules 4.

[0085] Specifically, such as Figure 9 As shown, the air blowing module 4 includes an air pipe 41, air pipe connectors 42 disposed at both ends of the air pipe 41, and multiple nozzles 43 disposed on the air pipe 41 and connected to the air pipe 41. The number of nozzles 43 and their orientation in the same plane perpendicular to the direction of conveying the waste product to be removed are as follows: Figure 1 The number of roller clamp modules 3 in the y direction are the same and they are set one-to-one. The nozzles 43 face the roller clamp modules 3 and are set downward.

[0086] Compressed air enters the ventilation pipe 41 through the air pipe connector 42 and is sprayed out through the nozzle 43 onto the waste products to be removed below the roller clamp module 3.

[0087] When each roller clamp module 3 is arranged along the y-direction, the number of nozzles 43 is the same as the number of roller clamp modules 3. Along the conveying direction of the waste product to be removed, each roller clamp module 3 has a nozzle 43 at the front and rear. The nozzles 43 face the roller clamp module 3 and are set downwards, so that the nozzles 43 blow the waste product to be removed below the roller clamp module 3 from top to bottom at an angle. This can better disperse the waste wires and make the waste wires blow out from the cutting groove.

[0088] In this embodiment, air pipe connectors 42 are provided at both ends of the air pipe 41. The air pipe connectors 42 are connected to a compressed air supply device (not shown in the figure). Compressed air is injected into the air pipe 41 from both ends through the compressed air supply device. After the compressed air is buffered in the air pipe 41, the compressed air is evenly distributed to each nozzle 43, so that the airflow from each nozzle 43 on the same air pipe 41 is relatively consistent, so as to blow away the waste wires below each roller clamp module 3.

[0089] Furthermore, both ends of the vent pipe 41 are provided with a first connector 44 and a second connector 45. The second connector 45 is fixed to the first connector 44 (for example, by means of screws and threaded holes) to fix the end of the vent pipe 41 between the first connector 44 and the second connector 45. Both ends of the vent pipe 41 are installed on the bottom of the mounting plate 1 through the first connector 44.

[0090] refer to Figure 4-7 The mounting frame 31 has a cavity 311 inside to accommodate the moving roller 32, and has openings 312 at the top and bottom that communicate with the cavity 311.

[0091] In the same plane, in a direction perpendicular to the direction of conveying the waste product to be removed (i.e.) Figure 1 In the y direction), each side of the mounting frame 31 is provided with a movable roller 32, and the rollers 324 of the movable roller 32 are fitted with bearings 33 at both ends. The bearings 33 are mounted on the mounting frame 31 by locking blocks 313.

[0092] The cavity 311 is connected to the suction module 2 through the opening 312 at the top of the mounting frame 31. When the two moving rollers 32 in the roller clamping module 3 rotate to the point where the two cut surfaces 322 are opposite each other, the first channel is formed inside the cavity 311. The bottom of the first channel is connected to the opening 312 at the bottom of the mounting frame 31. Under the action of the suction module 2, the waste filaments enter the first channel through the opening 312 at the bottom of the mounting frame 31 and are then drawn away by the suction module 2 through the opening 312 at the top of the mounting frame 31.

[0093] By placing a bearing 33 between the locking block 313 and the mounting frame 31, the moving roller 32 can rotate relative to the mounting frame 31, thereby reducing the friction between the moving roller 32 and the mounting frame 31.

[0094] Further reference Figure 5 One end of the roller 324 is fitted with a collar 34, a gear mounting piece 35, and a gear 36 in sequence on the outside of the bearing 33. The gear mounting piece 35 can be locked in the radial direction of the roller 324 by a set screw. The collar 34 is held between the bearing 33 and the gear mounting piece 35. The gear 36 is mounted on the gear mounting piece 35. A retaining ring 37 is provided on the side of the gear 36 away from the gear mounting piece 35. The retaining ring 37 is fixed to the end of the roller 324 (for example, by using a screw to engage a threaded hole to fix the retaining ring 37 to the end of the roller 324). The retaining ring 37 and the collar 34 lock the gear 36 in the axial direction of the roller 324, so that the rotation of the moving roller 32 can drive the gear 36 fixed on it to rotate synchronously.

[0095] The gears 36 at the ends of the two moving rollers 32 in each roller clamp module 3 are engaged;

[0096] The roller clamp drive mechanism includes a power output component 38, a synchronous pulley 39, and a synchronous belt (not shown in the figure). The power output component 38 is mounted on the mounting plate 1. The other end of the roller shaft 324 of one of the moving rollers 32 in each roller clamp module 3 is fixedly mounted with a synchronous pulley 39 on the outside of the bearing 33. The synchronous pulleys 39 in two adjacent roller clamp modules 3 are connected by a synchronous belt. The power output end of the power output component 38 is connected to the synchronous pulley 39, and the power output component 38 drives the synchronous pulley 39 connected to it to rotate.

[0097] In this embodiment, the outer side of bearing 33 refers to the side of bearing 33 that is away from the other end of roller 324. The power output component 38 can be a motor or other drive structure, and this embodiment does not impose specific limitations.

[0098] The power output component 38 can be provided as a single unit or multiple units. When only one power output component 38 is provided, two adjacent synchronous pulleys 39 are connected by a synchronous belt. The power output component 38 drives the synchronous pulley 39 connected to it to rotate. Another synchronous pulley 39 connected to this synchronous pulley 39 by the synchronous belt also rotates. Under the connection of the synchronous belt, when the power output component 38 drives the synchronous pulley 39 connected to it to rotate, the other synchronous pulleys 39 also rotate accordingly. The rotation of the synchronous pulleys 39 causes the gear 36 at the other end of the roller 324 to rotate, and another gear 36 meshing with it also rotates accordingly. The two moving rollers 32 in each roller clamp module 3 rotate in opposite directions. When multiple power output components 38 are provided, each roller clamp module 3 can be divided into multiple groups. Each group of roller clamp modules 3 is provided with one power output component 38. The synchronous pulleys 39 in each group are connected by a synchronous belt. The power output component 38 is connected to one of the synchronous pulleys 39 in the group and drives the moving rollers 32 in the group to rotate through the power output component 38.

[0099] Furthermore, both gear 36 and timing pulley 39 are located on the outside of mounting bracket 31.

[0100] In a preferred embodiment, such as Figure 5 As shown, the cutter 323 is disposed on the moving roller 32, which is equipped with the synchronous pulley 39, near the cutting surface 322 at the rear end of the roller clamping surface 321 along its rotation direction. That is, the cutter 323 is disposed on the moving roller 32, which is equipped with the synchronous pulley 39. Specifically, along the rotation direction of the moving roller 32, the cutter 323 is disposed on the rear end of the roller clamping surface 321 of the moving roller 32 near the cutting surface 322.

[0101] In a further preferred embodiment, refer to Figure 7 Along the conveying direction of the waste products to be removed, the front and rear side walls of the mounting frame 31 are provided with adjustment grooves 314 that penetrate the mounting frame 31 and communicate with the cavity 311.

[0102] The adjustment groove 314 includes a first adjustment groove 3141 and a second adjustment groove 3142 arranged vertically, and a third adjustment groove 3143 and a fourth adjustment groove 3144 arranged horizontally. The first adjustment groove 3141 is located between the two moving rollers 32. One end of the first adjustment groove 3141 is connected to one end of the third adjustment groove 3143. The other end of the third adjustment groove 3143 is connected to one end of the second adjustment groove 3142. The other end of the second adjustment groove 3142 is connected to one end of the fourth adjustment groove 3144. The other end of the fourth adjustment groove 3144 passes through the side wall of the mounting frame 31.

[0103] The side wall of the mounting frame 31, which is penetrated by the other end of the fourth adjustment groove 3144, is provided with a through hole (not shown in the figure) that penetrates the mounting frame 31. One end of the through hole is connected to the second adjustment groove 3142. An elastic element 315 is provided in the through hole. One end of the elastic element 315 passes through the second adjustment groove 3142 and abuts against the mounting frame 31. An adjustment element (not shown in the figure) is inserted into the through hole. One end of the adjustment element can abut against the other end of the elastic element 315. By turning the other end of the adjustment element, the elastic deformation of the elastic element 315 can be changed to change the width of the first adjustment groove 3141, thereby adjusting the distance between the two moving rollers 32 on the mounting frame 31.

[0104] In this embodiment, the adjusting member can be a screw, and the through hole has a thread that matches the screw. The elastic member 315 can be a spring, preferably a rectangular spring. The elastic member 315 is disposed in the through hole, one end of which can pass through the second adjusting groove 3142 and be connected to or not connected to the mounting bracket 31, and the other end can be connected to or not connected to the adjusting member. The end of the adjusting member away from the elastic member 315 extends out of the mounting bracket 31 to facilitate screwing the adjusting member. Before the waste removal begins, the adjusting member is screwed according to the waste wire size and process requirements to change the position of the adjusting member in the through hole, thereby adjusting the elastic deformation of the elastic member 315. Under the action of the elastic member 315, a force can be applied to the mounting bracket 31 between the first adjusting groove 3141 and the second adjusting groove 3142, thereby adjusting the width of the first adjusting groove 3141. Furthermore, during the waste removal process, the different amounts of waste filaments drawn into the first channel by the suction module 2 will result in different sizes of waste filaments being clamped by the roller clamp. Under the action of the elastic element 315, the roller clamp module 3 can adapt to waste filaments of different sizes.

[0105] refer to Figure 3 and Figure 8 The suction module 2 in this embodiment includes an air duct 21 and a plurality of connecting pipes 22 disposed at the bottom of the air duct 21 and connected to the air duct 21. The number of connecting pipes 22 is the same as the number of roller clamp modules 3 and is arranged in a one-to-one correspondence. The end of the connecting pipe 22 away from the air duct 21 is mounted on the mounting plate 1.

[0106] The two moving rollers 32 in the roller clamp module 3 rotate to form a first channel with opposite tangent surfaces 322, which is connected to the connecting pipe 22 above them.

[0107] The mounting plate 1 below the connecting pipe 22 has a slot 15 that penetrates the mounting plate 1, so that the connecting pipe 22 can be connected to the first channel.

[0108] During suction, when the two moving rollers 32 in the roller clamping module 3 rotate to face each other at the cutting surfaces 322, the waste filaments are sequentially drawn through the first channel and connecting pipe 22 to the air duct 21, and then to an external storage device (not shown in the figure) for unified processing. When the two moving rollers 32 in the roller clamping module 3 rotate to face each other at the clamping surfaces 321, the clamped waste filaments and the waste filaments above the gap after being cut by the cutter 323 are drawn into the connecting pipe 22 and then into the air duct 21, and then to an external storage device for processing. That is, the waste filaments drawn into each connecting pipe 22 are all conveyed to the air duct 21 and then to the storage device for unified processing.

[0109] In one specific embodiment, one end of the air duct 21 is provided with an air extraction port and the other end is provided with an observation port. The observation port is sealed by a sealing plate 23, and a sealing gasket 24 is provided between the observation port and the sealing plate 23 to prevent gas from leaking from the observation port.

[0110] Along the direction away from the observation port, the height of the air duct 21 gradually increases.

[0111] An external air extraction device (not shown in the figure) is connected to the air extraction port. When the air extraction device is activated, the waste filaments are conveyed to the air duct 21 through the connecting pipe 22.

[0112] Along the direction away from the observation port, the height of the air duct 21 gradually increases. For example, the air duct 21 can be designed as a conical structure to make the air supply of each connecting pipe 22 more uniform, that is, the suction force generated is more uniform and consistent.

[0113] Furthermore, to accommodate installation space requirements, an angled connecting pipe 25 can be connected to one end of the air extraction port in the air duct 21. The angled connecting pipe 25 has a certain angle, such as 90°, to change the direction of air extraction. The angled connecting pipe 25 and the air extraction device can be connected via an adapter pipe 26.

[0114] To prevent gas leakage during the extraction process, sealing gaskets 24 can be installed between the angled connecting pipe 25 and the air duct 21 and the adapter pipe 26.

[0115] refer to Figure 1-2 The top of the mounting plate 1 is equipped with an upper cover 6, and the air duct 21 and each connecting pipe 22 are located inside the upper cover 6.

[0116] The bottom of the mounting plate 1 is equipped with a lower cover 7. The roller clamp module 3 and the air blowing module 4 are both located inside the lower cover 7. The top of the mounting frame 31 is connected to the bottom of the mounting plate 1, and the bottom of the mounting frame 31 is connected to the lower cover 7.

[0117] The upper shield 6 and lower shield 7 ensure that the entire waste removal process takes place within the space formed by the mounting plate 1 and the upper and lower shields 6 and 7. This prevents waste wires from falling into areas outside the waste removal channel (i.e., the first channel, connecting pipe 22) during the waste removal process, thus preventing waste wires from getting tangled on the waste removal components and affecting the normal operation of the waste removal process. Furthermore, dust is generated during laser cutting and accumulates on the carrier plate. The upper and lower shields 6 prevent dust blown out during the waste removal process from entering areas outside the waste removal channel.

[0118] In this embodiment, the bottom of the mounting frame 31 can be connected to the lower cover 7 via an adapter plate 8. Along the conveying direction of the product to be removed, an adapter plate 8 is connected to the bottom of both the front and rear side walls of the mounting frame 31, and the adapter plate 8 is mounted on the lower cover 7. Preferably, the adapter plate 8 is mounted on the side wall of the lower cover 7. To ensure that the adapter plate 8 does not affect the blowing of the nozzle 43, an insertion hole 81 for the nozzle 43 to pass through can be opened on the adapter plate 8, so that the airflow ejected from the nozzle 43 can act on the product to be removed below the roller clamp module 3.

[0119] Furthermore, several weight-reducing holes 16 can be made on the mounting plate 1 to reduce the weight of the mounting plate 1.

[0120] During the process of removing waste filaments formed after laser cutting using the waste removal device described in the embodiments of this application:

[0121] First, the air blowing module 4 blows at an angle onto the area of ​​the product to be removed that needs to be removed, which is conveyed to the roller clamp module 3 below. This blows away the waste filaments that are not adsorbed and fixed on the carrier plate, and the waste filaments embedded in the cutting groove of the carrier plate can be blown out of the cutting groove.

[0122] Then, the two moving rollers 32 in each roller clamping module 3 first rotate until the two cut surfaces 322 face each other to form a first channel. Under the action of the suction module 2, the waste filaments below the roller clamping module 3 are sequentially sucked into the air duct 21 through the first channel and the connecting pipe 22. The waste filaments not sucked into the air duct 21 are partially located in the first channel under the action of the suction module 2. The two moving rollers 32 in the roller clamping module 3 continue to rotate until the two roller clamping surfaces 321 face each other, forming a gap for clamping the waste filaments. At this time, the first channel becomes a gap. During the process of the two moving rollers 32 in the roller clamping module 3 rotating from one end of the roller clamping surface 321 to the other end of the roller clamping surface 321, the two roller clamping surfaces 321 cooperate with each other. An upward force is generated to pull the waste filaments away from the carrier plate and is then drawn away by the suction module 2. If, when rotating from one end of the roller clamping surface 321 to the other end, there are still waste filaments connected to the conductive pattern, the waste filaments fail to completely detach from the carrier plate. When the moving roller 32 rotates to the point where the cutter 323 is within the gap, the cutter 323 cuts the waste filaments within the gap under the rotation of the moving roller 32. The waste filaments above the gap are drawn away by the suction module 2. The waste filaments below the gap can be removed manually or mechanically after all the waste filaments of the entire product to be removed have been removed by the waste removal device of this embodiment.

[0123] The waste removal device of this embodiment can effectively remove waste filaments from the product to be removed after laser cutting, with high waste removal efficiency and less risk of damaging the conductive patterns that need to be retained.
