Description

Technical Field

[0001] This invention belongs to the field of chip mounter feeding technology, specifically relating to a chip mounter feeding mechanism for integrated circuit board production. Background Technology

[0002] In the integrated circuit board manufacturing process, surface mount technology is an indispensable core process that requires the use of automated placement equipment. The feeding mechanism, as the "material conveying hub" of the automated placement equipment, is responsible for accurately delivering surface mount components such as resistors, capacitors, and chips to the pick-up position of the placement head.

[0003] Currently, the feeding mechanism of automated chip mounting does not integrate a component cleaning structure, requiring manual wiping of component surfaces with a lint-free cloth. This is not only inefficient but also prone to uneven cleaning results due to differences in manual operation. Although some high-end mechanisms are equipped with cleaning functions, they mostly use independent high-pressure air blowing or brush cleaning modules, which are disconnected from the feeding process, leading to quality problems such as poor soldering and short circuits in subsequent chip mounting. Therefore, those skilled in the art provide a chip mounting feeding mechanism for integrated circuit board production to solve the above-mentioned problems. Summary of the Invention

[0009] As a further optimization of the present invention, the front sidewall of the third link is provided with a feeding tooth drive assembly. The feeding tooth drive assembly includes a fixed side plate fixedly installed on the front sidewall of the third link. The rear sidewall of the fixed side plate is rotatably connected with a pawl that cooperates with the corresponding ratchet. The top of the feeding platform is fixedly installed with a mounting plate. The top of each mounting plate is fixedly installed with a limit seat. The bottom of each limit seat is fixedly installed with a return spring that is fixedly connected to the top of the corresponding pawl.

[0010] As a further optimization of the present invention, the electronic component cleaning assembly includes a reciprocating seat rotatably connected to the top of the front sidewall of the first connecting rod.

[0013] As a further optimization of the present invention, each of the fixed bases has a discharge port at its bottom, and each discharge port is connected to a corresponding waste conveying trough.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. In this invention, the electric push cylinder of the feeding component is used as the core power source. Through the first link, the second link and other link assemblies, the power is synchronously transmitted to the electronic component cleaning component and the waste material auxiliary guiding component. When the first link swings, it can drive the subsequent link to drive the feeding gear to complete the feeding action, and it can also drive the cleaning component to move through the reciprocating seat and reciprocating link. At the same time, the second link can drive the waste material guiding structure to operate.

The take-up reel corresponds to the feeding plate to realize the classified take-up of waste. This closed-loop structure avoids waste scattering, eliminates the need for frequent manual cleaning, and facilitates subsequent waste recycling, which meets the requirements of green production.

[0032] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] Example 1: As Figure 1 , Figure 2 As shown, a chip mounting feeding mechanism for integrated circuit board production includes a feeding assembly 1, a loading assembly 2, a guiding assembly 3, a waste material winding assembly 4, an electronic component cleaning assembly 5, a feeding gear drive assembly 6, a waste material auxiliary guide assembly 7, and a control module. The control module includes a controller installed on the circuit board chip mounter. The loading assembly 2 serves as the overall mounting base, integrating all components into a stable working system. The feeding assembly 1 is the core feeding component, responsible for accurately conveying electronic components to the mounting position. The guiding assembly 3 ensures accurate component conveying direction. The waste material winding assembly 4 realizes centralized recycling of waste materials. The electronic component cleaning assembly 5 removes impurities from the component surface. The feeding gear drive assembly 6 provides power to the feeding gears. The waste material auxiliary guide assembly 7 assists in the smooth conveying of waste materials. All components cooperate with each other to form a complete automatic feeding process.

[0034] like Figure 1 , Figure 2As shown, the feeding assembly 2 includes a mounting bracket 201 fixedly mounted on the pick-and-place machine. Connecting discs 203 are fixedly mounted on the front and rear sides of the inner wall of the mounting bracket 201. A mounting rod is rotatably connected between the two connecting discs 203. A feeding disc 202, corresponding in number and cooperating with several guide assemblies 3, is mounted on the outer wall of the mounting rod. The mounting bracket 201 is connected to the pick-and-place machine body via bolts or other fasteners, providing stable mounting support for the entire feeding machine. The connecting discs 203 are fixed to the inner wall of the mounting bracket 201 and are used to mount and fix the mounting rods. The mounting rods can rotate around the connecting discs 203, causing the feeding discs 202 to rotate synchronously. Electronic components to be fed are wound on the feeding discs 202. During the feeding process, the feeding tray 202 rotates with the mounting rod as the feeding component 1 pulls it, continuously releasing the feeding tape. The tape enters the feeding component 1 through the guide component 3. The mounting frame 201 is made of high-strength alloy material, which has good load-bearing capacity and stability, effectively preventing component displacement caused by vibration during feeding and ensuring feeding accuracy. The number of feeding trays 202 and guide components 3 corresponds, which can simultaneously realize the conveying of multiple different types of electronic components, improving the compatibility and working efficiency of the feeder. The rotational connection structure between the mounting rod and the connecting plate 203 is reasonably designed with low rotational resistance, which can reduce the jamming phenomenon when the feeding tray 202 releases the tape and ensure the continuity of tape conveying.

[0035] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, each feeding assembly 1 includes a mounting base 101 fixedly mounted on the pick-and-place machine. A fixed base 103 is fixedly mounted on the top of each mounting base 101. A feeder 104 is fixedly mounted on the top of each fixed base 103. Each feeder 104 has a feeding platform 105 on its top, and each feeding platform 105 is connected to a corresponding guide assembly 3. Each fixed base 103 has a discharge port 102 at its bottom, and each discharge port 102 is connected to a corresponding waste conveying trough 701. The inner wall of each feeder 104 is located at the inlet... An electric pusher cylinder 106 is fixedly installed on one side of the material end. The output end of each electric pusher cylinder 106 is fixedly connected to a reciprocating slider 107 slidably connected inside the feeder 104. A swing link 113 is rotatably connected to the inner wall of each reciprocating slider 107. The other end of the swing link 113 is rotatably connected to a first link 108. The upper end of the rear side wall of each first link 108 is rotatably connected to the side wall of the corresponding feeder 104. A second link 109 is rotatably connected to the lower part of the rear side wall of each first link 108. A second link 109 is rotatably connected to one side of the rear side wall of each second link 109. A third link 110 is rotatably connected to the feeder 104. A ratchet 111 is rotatably connected to the rear side wall of each third link 110. A feeding gear 112, rotatably connected to the side wall of the corresponding feeder 104, is fixedly mounted on the rear side wall of each ratchet 111. The mounting base 101 is fixed to the pick-and-place machine by welding or bolting, providing a stable mounting foundation for the feeding assembly 1. A fixed base 103 is fixed to the top of the mounting base 101 for mounting the feeder 104, ensuring the feeder 104 is fixed in position. A feeding platform 105 is positioned on top of the feeder 104, serving as... The conveying channel for electronic component strips has toothed grooves on the strip that mesh with the feeding gear 112. After the strip enters the feeding platform 105 from the guide assembly 3, it moves along the feeding platform 105 under the drive of the feeding gear 112. The electric push cylinder 106 serves as a power source. After the power is turned on, the controller configures the parameters to make its output end perform reciprocating linear motion, which drives the reciprocating slider 107 to slide in the groove inside the feeder 104. When the reciprocating slider 107 slides, it drives the first connecting rod 108 to swing around its connection point with the side wall of the feeder 104 through the swing connecting rod 113.

[0036] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, during the swing of the first link 108, it drives the second link 109 to move, and the second link 109 further drives the third link 110 to move. When the third link 110 moves, it drives the ratchet 111 to rotate. Since the ratchet 111 is fixedly connected to the feeding gear 112, the feeding gear 112 rotates synchronously with the ratchet 111. The feeding gear 112 meshes with the toothed holes on the material belt, thereby driving the material belt to move along the feeding platform 105 to realize the conveying of electronic components. The discharge port 102 is connected to the waste conveying trough 701. During the conveying of the material belt, the stripped waste material, such as the carrier part of the material belt, enters the waste conveying trough 701 through the discharge port 102 and is then conveyed to the waste winding assembly 4. The mounting base 101 and the fixed base 103 are made of rigid materials, with a stable structure, which can effectively reduce the vibration during the feeding process, ensure the precise meshing of the feeding gear 112 with the toothed holes of the material belt, and improve the feeding accuracy.

[0037] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the output speed and stroke of the electric push cylinder 106 can be precisely adjusted by the control system, which can adjust the feeding speed and feeding amount according to the feeding requirements of different types of electronic components, thereby improving the adaptability of the feeder. The power is transmitted through the first connecting rod 108, the second connecting rod 109, the third connecting rod 110, and the swing connecting rod 113, ensuring smooth motion transmission and effectively avoiding impact and vibration during power transmission, thus extending the service life of the mechanism. The feeding gear 112 is driven by meshing with the tooth holes of the material belt, which ensures the synchronicity and stability of the material belt conveying, avoids material belt slippage or deviation, and ensures that the electronic components are accurately placed at the mounting position. Fifth, the setting of the discharge port 102 realizes the timely separation of waste and electronic components, avoids waste accumulation from affecting the feeding process, and provides a channel for subsequent waste recycling.

[0038] like Figure 1 , Figure 2As shown, each feeding assembly 1 has a guide assembly 3 fixedly connected to its inlet end. The guide assembly 3 typically consists of several guide rollers, guide plates, and adjusting components. One end of the guide assembly 3 corresponds to the loading tray 202, and the other end is connected to the feeding platform 105. The electronic component strip belonging to the loading tray 202 first enters the guide assembly 3. Under the support of the guide rollers and the limiting action of the guide plates, the strip is guided to the preset conveying path and then smoothly enters the feeding platform 105. The adjusting components can adjust the spacing between the guide rollers and the position of the guide plates according to the width and thickness of the strip. The guide assembly 3 ensures that the material belt does not deviate or jam during the conveying process. It can effectively correct any deviation that may occur when the material belt is released from the bottom to the upper material tray 202, ensuring that the material belt enters the feeding platform 105 with a precise posture. This lays the foundation for the precise meshing of the subsequent feeding gear 112 with the material belt teeth and improves the overall feeding accuracy. The rolling action of the guide roller can reduce the friction during the material belt conveying process, avoid damage to the material belt surface due to friction, and protect the integrity of electronic components. The design of the adjustment component allows the guide assembly 3 to adapt to material belts of different widths and thicknesses, improving the versatility of the feeder.

[0039] like Figure 7 , Figure 8 As shown, each third link 110 has a feeding gear drive assembly 6 on its front side wall. Each feeding gear drive assembly 6 includes a fixed side plate 601 fixedly installed on the front side wall of the third link 110. The rear side wall of each fixed side plate 601 is rotatably connected to a pawl 602 that cooperates with the corresponding feeding gear 112. A mounting plate 605 is fixedly installed on the top of each feeding platform 105. A limit seat 603 is fixedly installed on the top of each mounting plate 605. A return spring 604 fixedly connected to the top of the corresponding pawl 602 is fixedly installed on the bottom of each limit seat 603. 601 is fixed to the front side wall of the third link 110 by bolts and moves synchronously with the third link 110; pawl 602 is rotatably connected to the rear side wall of the fixed side plate 601, one end of which engages with the tooth groove on the feeding gear 112, and the other end is connected to the return spring 604; mounting plate 605 is fixed to the top of the feeding platform 105 and is used to install the limit seat 603; the limit seat 603 plays a role in fixing and limiting the return spring 604; the return spring 604 is always in a stretched state, applying a pulling force to the pawl 602, so that the pawl 602 remains engaged with the tooth groove of the feeding gear 112.

[0040] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, when the third link 110 moves forward under the drive of the second link 109, the fixed side plate 601 drives the pawl 602 to move forward. The pawl 602 engages with the tooth groove of the ratchet 111, pushing the ratchet 111 and the feeding gear 112 to rotate synchronously. Taking the installation direction of the feeding gear 112 as an example; when the third link 110 moves backward, the pawl 602 rotates around the connection point of the fixed side plate 601 under the pressure of the tooth surface of the feeding gear 112, disengaging from the tooth groove of the feeding gear 112, and simultaneously stretching the return spring 604. When the pawl 602 moves to the next tooth groove position, under the pulling force of the return spring 604, the pawl 602 engages with the tooth groove of the feeding gear 112 again, preparing for the next push of the feeding gear 112 to rotate. The cooperation between the pawl 602 and the feeding gear 112 enables the unidirectional intermittent rotation of the feeding gear 112, ensuring that the material belt can only move in the feeding direction and preventing the material belt from reversing during the return stroke of the feeding assembly 1, thus ensuring the accuracy and stability of the feeding. The reset spring 604 ensures that the pawl 602 always maintains effective engagement with the tooth groove of the feeding gear 112, preventing transmission failure caused by the pawl 602 loosening or shifting, and improving the reliability of the drive assembly. The structural design of the fixed side plate 601 and the mounting plate 605 ensures that the components of the feeding gear drive assembly 6 are firmly installed, reducing shaking during movement and further ensuring transmission accuracy. This drive method has a simple structure, and the parts are easy to process and replace, reducing the maintenance cost of the mechanism.

[0041] like Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 As shown, each electronic component cleaning assembly 5 includes a reciprocating seat 505 rotatably connected to the top of the front sidewall of the first connecting rod 108. A reciprocating connecting rod 501 is rotatably connected to the front sidewall of each reciprocating seat 505. A fixing block 502 is fixedly installed on both the front and rear sidewalls of each feeding platform 105. A groove is formed on the front sidewall of each fixing block 502, and a slider 503 is slidably connected to the inner sidewall of the corresponding groove. Several cleaning sponges 504 are installed between two corresponding sliders 503. The rear sidewall of each reciprocating connecting rod 501 is rotatably connected to the front sidewall of the corresponding slider 503. The seat 505 is rotatably connected to the top of the front side wall of the first connecting rod 108 and moves synchronously with the swing of the first connecting rod 108; one end of the reciprocating connecting rod 501 is rotatably connected to the reciprocating seat 505, and the other end is rotatably connected to the slider 503, which plays the role of transmitting motion; the fixed block 502 is fixed to the front and rear side walls of the feeding platform 105, and the groove opened on it provides guidance for the sliding of the slider 503; the slider 503 slides in the groove, driving the cleaning sponge 504 to move synchronously; the cleaning sponge 504 is made of high-density, high-absorbency material, with a soft surface, which can effectively absorb dust, debris and other impurities on the surface of electronic components.

[0042] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, when the first connecting rod 108 swings around its connection point with the side wall of the feeder 104, it drives the reciprocating seat 505 to perform an arc motion. The reciprocating seat 505 pulls the slider 503 to perform a reciprocating linear motion in the groove of the fixed block 502 through the reciprocating connecting rod 501. The slider 503 drives the cleaning sponge 504 to perform a reciprocating motion above the feeding platform 105. When the electronic component material belt is conveyed along the feeding platform 105, the cleaning sponge 504 contacts the surface of the electronic component and absorbs and removes the impurities on the surface, thereby cleaning the electronic component. Each waste material auxiliary guide assembly 7 includes a waste material conveying groove 701 respectively opened between the fixed base 103 and the feeder 104, and the rear side wall of each second connecting rod 109 A lifting plate 702 is rotatably connected, and a driven gear 704 is rotatably connected to the rear side wall of each lifting plate 702. A limiting groove 706 is opened on the side wall of each waste conveying trough 701. A guide roller 705 is fixedly installed on the rear side wall of each driven gear 704 and movably connected inside the corresponding waste conveying trough 701. A rack 703 that meshes with the corresponding driven gear 704 is also fixed on the side wall of each limiting groove 706. The waste conveying trough 701 provides a channel for conveying waste. One end of it is connected to the discharge port 102, and the other end corresponds to the waste winding assembly 4. After the waste enters the waste conveying trough 701 from the discharge port 102, it moves along the trough to the waste winding assembly 4.

[0043] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 10As shown, the lifting plate 702 is rotatably connected to the rear wall of the second connecting rod 109 and moves synchronously with the movement of the second connecting rod 109; the driven gear 704 is rotatably connected to the rear wall of the lifting plate 702 and meshes with the rack 703 on the inner wall of the waste conveying trough 701; the guide roller 705 is fixed to the rear wall of the driven gear 704, located inside the waste conveying trough 701, and in contact with the waste. When the second connecting rod 109 moves under the drive of the first connecting rod 108, it drives the lifting plate 702 to move up and down. The lifting plate 702 drives the driven gear 704 to move up and down along the rack 703, and the driven gear 704 is limited by the limiting groove 706 so that the driven gear 704 is always meshed with the rack 703. Because the driven gear 704 is meshed with the rack 703, during the movement of the driven gear 704 up and down along the rack 703... During the process, rotation occurs; when the driven gear 704 rotates, it drives the guide roller 705 to rotate synchronously. The guide roller 705 contacts the waste in the waste conveying trough 701 and drives the waste along the waste conveying trough 701 towards the waste winding assembly 4 through friction. At the same time, the rotation of the guide roller 705 can also organize the waste. When the waste is fed through the waste conveying trough 701, since the material belt is mostly supported by plastic, it may bulge during the conveying process inside the waste conveying trough 701. When the waste belt bulges too high, it may cause feeding blockage. By the up and down movement and synchronous rotation of the guide roller 705, the bulging waste belt can be pressed down, improving the waste winding efficiency, and at the same time avoiding wrinkles or deviations in the waste during the conveying process, ensuring the smoothness of waste conveying.

[0044] like Figure 1 , Figure 2As shown, the waste material winding assembly 4 includes fixed plates 401 fixedly installed on the front and rear side walls of the mounting frame 201. A rotating rod 403 is rotatably connected between the two fixed plates 401. Several winding reels 404, corresponding to the number of feeding reels 202 and cooperating with the corresponding discharge ports 102, are fixedly sleeved on the outer side wall of the rotating rod 403. A servo motor 402 is fixedly installed on the front side wall of any fixed plate 401. The servo motor 402 is electrically connected to the controller. The output end of the servo motor 402 is fixedly connected to one end of the rotating rod 403. The fixed plates 401 are fixed to the front and rear side walls of the mounting frame 201 by bolts, providing stable support for the rotating rod 403. The rotating rod 403 is rotatably connected between the two fixed plates 401 by bearings and can rotate around its own axis. The winding reels 404 are connected to the feeding reels. The 202 units correspond to each other, and the position of each take-up reel 404 is aligned with the outlet of the corresponding waste conveying trough 701. It is used to take up the waste conveyed from the waste conveying trough 701. The servo motor 402 serves as the power source for waste take-up. After the power is turned on, its output end drives the rotating rod 403 to rotate at a constant speed through the parameter configuration of the controller. When the rotating rod 403 rotates, it drives all the take-up reels 404 to rotate synchronously. The take-up reels 404 wrap the waste around their outer side wall through friction, realizing the centralized take-up of the waste. At the same time, the speed of the servo motor 402 can be precisely adjusted by the control system to match the feeding speed of the feeding component 1 and the waste conveying speed of the waste auxiliary guide component 7, so as to avoid the waste being torn due to the excessive take-up speed or the waste accumulating in the conveying trough due to the excessive take-up speed.

[0045] It should be noted that in use, the feeding tray 202 with electronic component strip wound on it is mounted on the mounting rod. The mounting rod is rotatably connected to the inner wall of the mounting frame 201 via the connecting plate 203. After the control module is started, the traction force generated by the subsequent action of the feeding component 1 will drive the mounting rod to rotate around the connecting plate 203. The feeding tray 202 rotates synchronously with the mounting rod, continuously releasing the strip to provide raw materials for subsequent conveying. The strip released by the feeding tray 202 first enters the guide component 3. The guide rollers of the guide component 3 support the strip and reduce friction during strip conveying. The guide plate laterally limits the strip to prevent it from deviating. If the strip specifications are different, the spacing between the guide rollers and the position of the guide plate can be adjusted by adjusting the component to ensure that the strip smoothly enters the feeding platform 105 of the feeding component 1 along the preset path, laying the foundation for subsequent precise engagement.

[0046] The control module sends a command to the electric push cylinder 106 of the feeding assembly 1. The electric push cylinder 106 outputs reciprocating linear motion according to preset parameters (feeding speed, feeding amount), driving the reciprocating slider 107 fixedly connected to it to slide in the groove inside the feeder 104. When the reciprocating slider 107 slides, it drives the first connecting rod 108 to swing around its connection point with the side wall of the feeder 104 through the rotatably connected swing link 113. During the swing of the first connecting rod 108, it synchronously drives the second connecting rod 109 rotatably connected at the bottom to move. The second connecting rod 109 further pushes the third... The movement of the connecting rod 110 forms a complete power transmission chain, converting the linear motion of the electric push cylinder 106 into the rotational and oscillating power of the subsequent components. When the third connecting rod 110 moves, it drives the ratchet 111, which is rotatably connected to the rear side wall, to rotate. Since the ratchet 111 is fixedly connected to the feeding gear 112, the feeding gear 112 rotates synchronously with the ratchet 111. The feeding gear 112 precisely meshes with the toothed hole of the feeding platform 105. The rotating feeding gear 112 drives the feeding belt to move along the feeding platform 105 to the mounting position through the toothed hole, realizing the precise delivery of electronic components.

[0047] During the feeding process, the feeding gear drive assembly 6 ensures unidirectional movement of the material belt. The fixed side plate 601, which is fixed to the front side wall of the third link 110, moves synchronously with the third link 110. The pawl 602, which is rotatably connected to it, is always engaged with the tooth groove of the feeding gear 112 under the pulling force of the return spring 604 (the return spring 604 is fixed by the limit seat 603, which is installed on the mounting plate 605 of the feeding platform 105). When the third link 110 moves forward, the pawl 602 pushes the feeding gear 112 to rotate. When the third link 110 moves backward, the pawl 602 disengages from the tooth groove under the pressure of the tooth surface of the feeding gear 112, preventing the feeding gear 112 from reversing, preventing the material belt from returning backward, and ensuring feeding accuracy.

[0048] During the feeding stage, while power is transmitted, the swing of the first connecting rod 108 synchronously drives the electronic component cleaning assembly 5 to work. The reciprocating seat 505, which is rotatably connected to the top of the front side wall of the first connecting rod 108, swings in an arc motion with the first connecting rod 108. The reciprocating seat 505 pulls the slider 503 through the reciprocating connecting rod 501, which is rotatably connected. The slider 503 is slidably connected in the groove of the fixing block 502 on the front and rear side walls of the feeding platform 105. Under the pull of the reciprocating connecting rod 501, it moves in a reciprocating linear motion along the groove. The cleaning sponge 504 installed between the sliders 503 moves in a reciprocating motion synchronously with the slider 503. When the material belt is conveyed along the feeding platform 105, the cleaning sponge 504 comes into contact with the surface of the electronic component and uses its high-density adsorption to remove surface dust, debris and other impurities, ensuring the cleanliness of the component and avoiding impurities from affecting the chip mounting quality. Moreover, the soft sponge material will not damage the component.

[0049] During the feeding process, after the electronic components are stripped by the pick-and-place machine, the remaining waste (the material carrier) enters the waste conveying trough 701 of the waste auxiliary guiding assembly 7 through the discharge port 102 at the bottom of the fixed base 103 (the waste conveying trough 701 is located between the fixed base 103 and the feeder 104). When the second connecting rod 109 moves, it drives the lifting plate 702, which is rotatably connected to the rear side wall, to move up and down. The driven gear 704, which is rotatably connected to the rear side wall of the lifting plate 702, moves up and down along the rack 703 on the inner side wall of the waste conveying trough 701 with the lifting plate 702 (the limiting groove 706 limits the driven gear 704 to ensure that it is always meshed with the rack 703). During the meshing process, the driven gear 704 rotates, driving the guide roller 705 fixed to the rear side wall to rotate synchronously. The guide roller 705 is located inside the waste conveying trough 701 and comes into contact with the waste. The waste material is driven to move towards the waste winding assembly 4 by friction. At the same time, the rotating guide roller 705 can press down the raised waste material and straighten the wrinkles to prevent the waste material from clogging the conveying trough. The control module synchronously controls the servo motor 402 of the waste winding assembly 4 to start. The output end of the servo motor 402 drives the rotating rod 403 (the rotating rod 403 is rotatably connected to the mounting frame 201 through the fixing plate 401) to rotate. The winding material tray 404 on the outer wall of the rotating rod 403 rotates synchronously with the rotating rod 403. The number of winding material trays 404 corresponds to the number of feeding trays 202 and is aligned with the outlet of the waste conveying trough 701. The rotating winding material tray 404 wraps the waste material around its own outer wall by friction, realizing the centralized recycling of waste material. The speed of the servo motor 402 can be adjusted by the control module to match the feeding speed and waste material conveying speed to prevent the waste material from breaking or accumulating.
