Description

Technical Field

[0001] This utility model relates to assembly equipment for electronic products, and more particularly to a feeding device for automatically feeding mesh for mobile phone microphones. Background Technology

[0002] With the rapid development of science and technology and the continuous improvement of people's consumption level, the requirements for the quality of electronic products such as mobile phones, tablets, and headphones are also getting higher and higher. While demanding high quality, people also pursue a stylish appearance. As a result, more and more electronic products are designed to be smaller and thinner, and often have a certain curvature. Electronic products are also developing towards high-density integration and ultra-precision. Correspondingly, the requirements for assembly equipment of electronic products are also getting higher and higher.

[0003] In order to effectively assemble the microphone mesh in the mounting holes of the mobile phone frame, the requirements for the feeding efficiency and precision of the mesh are becoming increasingly stringent. Currently, mesh is mostly fed in sheet form, with multiple meshes arranged in a matrix on each sheet. However, the number of meshes on a sheet is limited, requiring frequent replacement of new sheets. This also involves the transfer and positioning of each sheet, resulting in relatively low feeding efficiency and inability to effectively guarantee feeding precision. Since the mesh is not a planar structure but a curved, dome-like structure, the protective film on the sheet is currently mostly peeled off manually using tweezers or a vacuum pen to expose the mesh. The mesh is then peeled off from the release paper of the sheet to be attached and placed in a convenient mounting position. Manual peeling is inefficient, and the precision of peeling and transferring cannot be guaranteed. Furthermore, due to the relatively small size of the mesh, manual peeling and transferring operations mostly need to be performed under a 3-5x tabletop magnifying glass or a 5-20x stereo microscope, which is labor-intensive and also results in ineffective guarantee of peeling precision and effect, making it unsuitable for the high-efficiency requirements of automated production lines.

[0004] Therefore, a feeding device with a simple structure, high feeding accuracy, and high efficiency is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device that is simple in structure, has high feeding accuracy, and is highly efficient.

[0006] To achieve the above objectives, this utility model provides a feeding device for automatically feeding mesh for mobile phone microphones. A release paper is adhered to the mesh to form a sheet of material. Multiple sheets of material are evenly spaced and adhered between a bottom tape and a top film, and then coiled into a roll to form a material roll. The feeding device includes, arranged sequentially from high to low at the opposite rear end of a support base, a top film reel for top film winding, a material roll reel for material roll loading, and a bottom tape reel for bottom tape winding, as well as a drive mechanism connected to the top film reel, the material roll reel, and the bottom tape reel to drive the three reels to rotate relative to the support base. The opposite front end of the support base is provided with... The material stripping platform and the material receiving platform are provided. The front end of the material stripping platform has a stripping section with a flat upper surface and a sloping lower surface. The top film of the starting end of the material roll loaded on the material roll reel is wrapped around the top film reel. The bottom strip of the starting end of the material roll is wrapped around the material stripping platform and then around the bottom strip reel. Under the action of the traction force of the driving mechanism and the pushing force of the material stripping section, each piece of material on the bottom strip is peeled off from the bottom strip one by one and pushed onto the material receiving platform. A blowing mechanism is arranged on the top end of the material receiving platform. The blowing mechanism blows air from the top obliquely through the blowing plate to blow the non-compliant pieces of material on the material receiving platform to the waste bin located at the opposite front end of the material receiving platform.

[0007] Preferably, the release paper includes an adhesive part and a positioning part connected as one piece, the mesh is pasted on the adhesive part, the width of the adhesive part is smaller than the width of the positioning part, an avoidance hole is provided at the connection between the positioning part and the adhesive part, and the width of the connection is less than or equal to the width of the adhesive part, and an observation hole is provided on the adhesive part.

[0008] Preferably, the positioning part, the fitting part and the positioning part are arranged in a one-to-one correspondence, or at least two fitting parts are connected at intervals on one positioning part, and the mesh is connected to the fitting part in a one-to-one correspondence.

[0009] Preferably, the bottom strip has at least one row of clearance holes evenly spaced along its length, the spacing between the clearance holes in each row corresponding to the spacing between the sheets on the bottom strip, and the shape and size of the clearance holes matching the shape and size of the mesh.

[0010] Preferably, the driving mechanism includes a drive motor and guide wheels arranged on the support base. The rotation shafts of the top film reel, the material reel, and the bottom belt reel are connected to the output shaft of the corresponding drive motor via couplings or synchronous belts to drive the three components to rotate. The guide wheels are arranged between the material reel and the top film reel, between the material reel and the stripping table, and between the stripping table and the bottom belt reel.

[0011] Preferably, the stripping table is provided with clearance grooves arranged along its longitudinal direction. The width of the clearance grooves corresponds to the width of the mesh of the sheet material, the depth of the clearance grooves corresponds to the height of the mesh of the sheet material, and the number of clearance grooves corresponds to the number of rows of mesh on the bottom belt.

[0012] Preferably, the blowing mechanism further includes a bracket mounted on the side of the support base, a horizontal motor mounted on the bracket, and a vertical cylinder connected to the output end of the horizontal motor. The blowing plate is connected to the output end of the vertical cylinder, thereby moving linearly in the front-back direction and the up-down direction under the drive of the horizontal motor and the vertical cylinder.

[0013] Preferably, the blowing mechanism further includes an adapter plate connected to the output end of the vertical cylinder and a cover plate mounted on the adapter plate. The cover plate is mounted on the adapter plate in an adjustable position along the front-back direction, and the blowing plate is mounted on the cover plate at an inclination.

[0014] Preferably, the blowing mechanism further includes an industrial camera located at the top side of the receiving platform, the industrial camera identifying from the top whether the receiving platform has the sheet material, the position coordinates of the sheet material, and the color of the mesh on the sheet material.

[0015] Preferably, the feeding device further includes a base, the base having at least one mounting slot, and each mounting slot having a corresponding support seat.

[0016] Compared with the prior art, the feeding device provided by this utility model, on the one hand, glues the mesh onto the release paper to form a sheet, and then glues each sheet at equal intervals between the bottom tape and the top film and coils them into a roll to form a material roll. In use, the material roll is loaded onto the material roll reel, and the top film at the beginning end of the material roll is wound around the top film reel. The bottom tape at the beginning end of the material roll is wound around the stripping table and then wound around the bottom tape reel. The receiving table and the stripping table are arranged facing each other, and the front end of the stripping table has a stripping part with a flat upper surface and a sloping lower surface. When the driving mechanism drives the top film reel connected to it, When the material reel and bottom tape reel rotate, the material reel rotates to release the material, the top film reel rotates to rewind the top film, and the bottom tape reel rotates to rewind the bottom tape. Each sheet is peeled off from the bottom tape one by one under the traction of the drive mechanism and the pushing force of the peeling section, and is pushed onto the receiving platform. This facilitates the assembly mechanism's handling of the peeled sheets. After the mesh on the sheet is attached to the assembly holes of the phone's frame, the release paper is removed. This simple and effective method achieves automatic mesh feeding, significantly improving peeling accuracy and feeding efficiency, meeting the high-efficiency requirements of automated production lines, unlike existing sheet-based feeding methods. Furthermore, a blowing mechanism is arranged on the top side of the receiving platform, and a waste bin is located on the front side. After peeling, the sheets on the receiving platform can be identified manually or using equipment such as an industrial camera. Qualified sheets remain on the receiving platform, awaiting removal, while unqualified sheets are blown into the waste bin by the blowing mechanism, further ensuring the peeling effect and avoiding subsequent ineffective operations. In addition, the top film tray, material roll tray, bottom belt tray, stripping table and receiving table are all arranged on the support base, so that the entire assembly can be loaded, unloaded and moved on the automated equipment through the support base, which facilitates loading, unloading and maintenance.

[0024] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] See Figures 1 to 7 This invention provides a feeding device 100 for automatically feeding mesh 200 for mobile phone microphones, so as to attach the mesh 200 to the mounting holes of the mobile phone frame. This invention uses roll feeding, reducing the frequency of material changes and effectively improving feeding efficiency. Specifically, the mesh 200 is a dome-shaped structure with a certain curvature, made of metal. The mesh 200 is adhered to a release paper 300 to form a sheet 400. Multiple sheets 400 are equally spaced and adhered between a correspondingly arranged bottom strip 500 and a top film 600, and coiled into a roll to form a roll 700. Each sheet 400 is adhered to the bottom strip 500 with the side containing the mesh 200 facing down, while the top film 600 covers the top side of each sheet 400.

[0026] Overall, the feeding device 100 provided in the preferred embodiment of this utility model includes a support base 10, a top film tray 20 for top film winding, a material roll tray 30 for loading material roll 700 and a bottom tape tray 40 for bottom tape winding, arranged sequentially from high to low on the opposite rear ends of the support base 10, and a drive mechanism 50 connected to the top film tray 20, material roll tray 30 and bottom tape tray 40 respectively to drive the three to rotate relative to the support base 10. The support base 10 has a stripping platform 60 and a receiving platform 70 arranged in opposite directions at its front end. The front end of the stripping platform 60 has a stripping part 61 with a flat upper surface and a sloping lower surface. The top film 600 at the beginning end of the material roll 700 loaded on the material roll 30 is wrapped around the top film plate 20. The bottom strip 500 at the beginning end of the material roll 700 is wrapped around the stripping platform 60 and then wrapped around the bottom strip plate 40. Under the action of the traction force of the drive mechanism 50 and the pushing force of the stripping part 61, each piece of material 400 on the bottom strip 500 is peeled off from the bottom strip 500 one by one and pushed onto the receiving platform 70. In addition, a blowing mechanism 80 is arranged at the top side of the receiving platform 70. The blowing mechanism 80 blows air from the top at an angle through the blowing plate 81 to blow the non-compliant sheet material 400 on the receiving platform 70 into the waste bin 82 located at the front side of the receiving platform 70.

[0027] Combination Figures 1 to 3To facilitate the pasting, positioning, peeling, and transfer of the release paper 300 and the mesh 200, the release paper 300 specifically includes an adhesive part 301 and a positioning part 302 connected as one unit. The mesh 200 is pasted on the adhesive part 301, specifically by double-sided adhesive to the bottom side of the adhesive part 301. That is, each piece of material 400 is pasted on the bottom tape 500 with the side of the release paper 300 with the mesh 200 facing down. The shape and size of the bonding portion 301 correspond to the shape and size of the mounting holes in the phone's mid-frame. The width of the bonding portion 301 is smaller than the width of the positioning portion 302, which facilitates the fixing of the precisely sized mesh 200. The positioning portion 302 provides more operating space, facilitating the transfer, stripping, and subsequent assembly of the mesh 200. The width of the connection between the bonding portion 301 and the positioning portion 302 is less than or equal to the width of the bonding portion 301, making it easy to bend and allowing the bonding portion 301 to smoothly enter the mounting holes in the phone's mid-frame. Furthermore, an avoidance hole 300a is provided at the connection between the positioning portion 302 and the bonding portion 301, effectively reducing the rigidity of the connection and facilitating bending. In addition, an observation hole 301a is also provided on the bonding portion 301, facilitating the observation and identification of the mesh 200 at its bottom end.

[0028] Specifically, in some embodiments, the bonding portion 301 and the positioning portion 302 are arranged in a one-to-one correspondence, so only one mesh 200 can be bonded to each release paper 300. In other embodiments, to improve feeding efficiency, each release paper 300 has one positioning portion 302 and at least two bonding portions 301. At least two bonding portions 301 are connected at intervals on one positioning portion 302, and the mesh 200 is connected to at least two bonding portions 301 in a one-to-one correspondence. Thus, at least two meshes 200 are bonded to each release paper 300, thereby enabling the feeding of at least two meshes 200 at a time. Figure 2 As shown, each release paper 300 has three meshes 200 attached to it.

[0029] Combination Figures 1 to 3 Specifically, to improve feeding efficiency, at least one column of sheet material 400 is arranged on the bottom belt 500, and the number of mesh yarns 200 on each sheet material 400 may be the same or different between different columns. For example, when only one column of sheet material 400 is arranged on the bottom belt 500, the number of mesh yarns 200 on each sheet material 400 can be multiple, thus enabling the feeding of multiple mesh yarns 200 at a time. Of course, when two or more columns of sheet material 400 are arranged on the bottom belt 500, the number of mesh yarns 200 on each column of sheet material 400 can be one or more, also enabling the feeding of multiple mesh yarns 200 at a time. In particular, when there are multiple columns of sheet material 400 on the bottom belt 500, and each sheet material 400 also has multiple mesh yarns 200, the feeding efficiency is even higher. Figure 3As shown, multiple sheets 400 are arranged in two columns on the bottom strip 500, and each column of sheets 400 has three mesh 200.

[0030] In addition, to improve the smoothness of material roll 700 feeding and conveying, at least one row of clearance holes 500a are equally spaced along the longitudinal direction on the bottom belt 500. The spacing between each row of clearance holes 500a corresponds to the spacing between each sheet 400 on the bottom belt 500, and the shape and size of the clearance holes 500a match the shape and size of the mesh 200, thereby facilitating the alignment and placement of the mesh 200 protruding from the bottom side of the sheet 400. Specifically, the number of rows of clearance holes 500a on the bottom belt 500 corresponds to the number of rows of sheets 400 on the bottom belt 500.

[0031] See Figures 3 to 6 The support base 10 includes a horizontal plate 11 and a vertical plate 12. The horizontal plate 11 is arranged horizontally in the front-to-back direction, and the vertical plate 12 is erected vertically on the opposite rear end of the horizontal plate 11. The stripping table 60 and the receiving table 70 are mounted on the opposite front end of the horizontal plate 11 in the front-to-back direction. The gap between the stripping table 60 and the receiving table 70 is slightly larger than the thickness of the bottom belt 500. The drive mechanism 50 includes a drive motor 51 arranged on the support base 10. The drive motor 51 is specifically mounted on the vertical plate 12. The top film plate 20, the material roll plate 30, and the bottom belt plate 40 are also mounted on the vertical plate 12, and the rotation shafts of the three are connected to the output shaft of the corresponding drive motor 51 through couplings or synchronous belts, so that they rotate under the drive of the drive motor 51. The three components and the drive motor 51 can be arranged in a one-to-one correspondence, with the three drive motors 51 driving the three components to rotate respectively. Of course, the three components can also be driven to rotate synchronously by one drive motor 51. Alternatively, there can be two drive motors 51, with one of the top film disc 20 and the bottom tape disc 40 rotating synchronously with the material roll 30 under the drive of the same drive motor 51, while the other rotates under the drive of another drive motor 51.

[0032] Specifically, the drive mechanism 50 also includes guide wheels 52. Multiple guide wheels 52 are arranged between the material roll 30 and the top film tray 20, between the material roll 30 and the stripping table 60, and between the stripping table 60 and the bottom belt tray 40, thereby guiding the conveying direction of the wound material roll 700. In some embodiments, to achieve better guiding effect, some guide wheels 52 have annular clearance grooves 52a on their peripheral sidewalls. The width of the clearance grooves 52a corresponds to the width of the mesh 200 on the sheet material 400, the depth of the clearance grooves 52a corresponds to the height of the mesh 200 on the sheet material 400, and the number of clearance grooves 52a corresponds to the number of rows of sheet material 400 on the bottom belt 500. When the sheet material 400 has multiple meshes 200 arranged side-by-side, the width of the clearance grooves 52a corresponds to the sum of the widths of each mesh 200.

[0033] See Figure 6 Specifically, the stripping table 60 is provided with clearance grooves 60a arranged along its longitudinal direction. The width of the clearance grooves 60a corresponds to the width of the mesh 200 on the sheet 400, the depth of the clearance grooves 60a corresponds to the height of the mesh 200 on the sheet 400, and the number of clearance grooves 60a corresponds to the number of rows of sheet 400 on the bottom belt 500. When the sheet 400 has multiple meshes 200 arranged side-by-side, the width of the clearance grooves 60a corresponds to the sum of the widths of each mesh 200.

[0034] See Figure 4 , Figure 5 and Figure 7 Specifically, the blowing mechanism 80 also includes a bracket 83 mounted on the side of the support base 10, a horizontal motor 84 mounted on the bracket 83, and a vertical cylinder 85 connected to the output end of the horizontal motor 84. The blowing plate 81 is connected to the output end of the vertical cylinder 85, thereby moving linearly in the front-back and up-down directions under the drive of the horizontal motor 84 and the vertical cylinder 85. The blowing plate 81 is provided with air holes, which are connected to an air source, thereby blowing defective products from the receiving table 70 to the waste bin 82.

[0035] See Figure 7 Specifically, in some embodiments, the blowing mechanism 80 further includes an adapter plate 86 connected to the output end of the vertical cylinder 85 and a cover plate 87 mounted on the adapter plate 86. The blowing plate 81 is mounted at an angle on the cover plate 87. The cover plate 87 not only houses the blowing plate 81 but also serves as a guide, making the air blown by the blowing plate 81 more concentrated and improving the blowing effect. The cover plate 87 is adjustable in position along the front-to-back direction on the adapter plate 86, thereby improving adaptability. Specifically, the adapter plate 86 has mounting holes 86a arranged along the front-to-back direction, and the cover plate 87 is selectively fixed to different positions of the mounting holes 86a by screws. Specifically, there are two mounting holes 86a, which are parallel and spaced apart in the left-to-right direction, thereby improving the stability of the cover plate 87 installation.

[0036] Specifically, in some embodiments, the blowing plate 81 is also angle-adjustably mounted on the cover plate 87, thereby adjusting the blowing angle as needed. Specifically, the blowing plate 81 can be pivotally connected to the cover plate 87 via a pivot shaft 811, thereby rotating around the pivot shaft 811 to adjust the placement angle between it and the cover plate 87. Alternatively, arc-shaped guide grooves 87a can be correspondingly formed at the upper ends of the two side walls of the cover plate 87, and positioning posts 812 can be correspondingly protruded on the two side walls of the blowing plate 81. The positioning posts 812 on both sides are slidably engaged in the two arc-shaped guide grooves 87a, thereby allowing the blowing plate 81 to rotate around the pivot shaft 811 through the sliding of the positioning posts 812 in the two arc-shaped guide grooves 87a, thereby adjusting the placement angle on the cover plate 87.

[0037] Combination Figure 3 , Figure 4 and Figure 7 The blowing mechanism 80 also includes an industrial camera 88 located at the top side of the receiving platform 70. The industrial camera 88 identifies the sheet material 400 on the receiving platform 70 from the top, specifically identifying whether the sheet material 400 is present, the position coordinates of the sheet material 400, whether the sheet material 400 has mesh 200, and the color of the mesh 200. The industrial camera 88 is arranged in a one-to-one correspondence with the receiving platform 70, or one industrial camera 88 moves back and forth between two receiving platforms 70, identifying the sheet material 400 on each platform. Specifically, the industrial camera 88 moves between the two receiving platforms 70 via a horizontal linear module 89. The industrial camera 88 is horizontally arranged and, through reflection from a prism 881 arranged opposite to it, is vertically positioned on the receiving platform 70. In addition, to improve the recognition effect, a light source 882 is provided between the industrial camera 88 and the receiving platform 70. The light source 882 is ring-shaped and can be mounted above the receiving platform 70, such as connected to the output end of the horizontal linear module 89, or connected to the output end of the horizontal motor 84.

[0038] See Figures 3 to 5 Specifically, in some embodiments, the feeding device 100 of this utility model further includes a base 90, on which at least one mounting slot 90a is provided. Support seats 10 are correspondingly slidably disposed in the mounting slots 90a, thereby facilitating and quickly loading and unloading of the material roll 700 by the sliding of the support seats 10 into and out of the base 90. Especially when the base 90 has two or more mounting slots 90a, the corresponding number of support seats 10 is also two or more, thereby achieving uninterrupted feeding through the alternating entry and exit of each support seat 10, further adapting to the high-efficiency requirements of automated production lines.

[0039] The mounting position 90a is equipped with a linear guide rail arranged in the front-to-back direction. The support base 10 slides on the linear guide rail. A handle can be installed on the support base 10, allowing it to be pushed into or pulled out of the base 90 manually. Alternatively, a push motor mounted on the base 90 and connected to the support base 10 can be used to drive the support base 10 to move linearly into and out of the base 90, thereby improving the accuracy of sliding into position. It should be noted that when the base 90 is present, the blowing mechanism 80 can be directly mounted on the base 90, thus eliminating the need for synchronous sliding with the support base 10.

[0040] Specifically, in some embodiments, in order to prevent the support seat 10 from shifting, a limiting cylinder 91 is provided at the edge of the opposite front end or rear end of the base 90. The output end of the limiting cylinder 91 is connected to a limiting post 92. Correspondingly, a limiting groove 10a that is in concave-convex cooperation with the limiting post 92 is provided on the outer side wall of the opposite front end or rear end of the support seat 10. When the support seat 10 slides into place in the placement slot 90a, the limiting post 92 moves linearly under the drive of the limiting cylinder 91 to insert into or exit the limiting groove 10a, thereby locking or unlocking the support seat 10 that has moved into place, preventing or allowing the support seat 10 to slide.

[0041] In addition, the feeding device 100 of this utility model also includes a control module, which is connected to components such as the top film plate 20, the material roll plate 30, the bottom belt plate 40, the drive mechanism 50, the blowing mechanism 80, and the push motor and limit cylinder 91 on the base 90, and is used to control the coordinated actions between the connected components. It should be noted that the specific structure and control principle of the control module are well known in the art, and therefore will not be described in detail here.

[0042] See Figures 1 to 7 The working principle of the feeding device 100 provided by this utility model will be explained as follows:

[0043] During operation, the material roll 700 is first loaded onto the material roll reel 30, and the top film 600 at the starting end of the material roll 700 is wound onto the top film reel 20. The bottom strip 500 is wound around the stripping table 60 and then onto the bottom strip reel 40. Then, the device is started, and the drive mechanism 50 is activated, driving the top film reel 20, material roll reel 30, and bottom strip reel 40 to rotate. As the bottom strip reel 40 and the material roll reel 30 rotate, the material roll 700 rotates accordingly to release the material. The pieces 400 on the bottom strip 500, under the traction force generated by the bottom strip 500 winding around the bottom strip reel 40, pass through the stripping section 61, and are thus released from the bottom strip 500 under the top resistance force provided by the stripping section 61. The sheets 400 are peeled off one by one and pushed onto the receiving platform 70 by inertia. At this time, the industrial camera 88 located above the receiving platform 70 performs visual recognition on the sheets 400 peeled onto the receiving platform 70 and feeds the recognition information back to the control module. Under the instruction of the control module, the blowing mechanism 80 is activated. The blowing plate 81 located at the top side of the receiving platform 70 moves down to approach the receiving platform 70 and moves horizontally relative to the receiving platform 70, thereby blowing the non-compliant sheets 400 into the waste bin 82 located at the front side of the receiving platform 70. The qualified products stay on the receiving platform 70 for picking and delivery. By continuously repeating the above actions, efficient feeding of the mesh 200 can be achieved.

[0044] Compared with the prior art, the feeding device 100 provided by this utility model, on the one hand, the mesh 200 is attached to the release paper 300 to form a sheet 400, and then each sheet 400 is attached at equal intervals between the bottom tape 500 and the top film 600 and coiled into a roll to form a material roll 700. In use, the material roll 700 is loaded onto the material roll reel 30, and the top film 600 at the beginning end of the material roll 700 is wound around the top film reel 20. The bottom tape 500 at the beginning end of the material roll 700 is wound around the stripping table 60 and then wound around the bottom tape reel 40. The receiving table 70 and the stripping table 60 are arranged facing each other, and the front end of the stripping table 60 has a stripping part 61 with a flat upper surface and a sloping lower surface. When the driving mechanism 50 drives the connected part... When the top film reel 20, the material reel 30, and the bottom tape reel 40 rotate, the material reel 30 rotates to release material, the top film reel 20 rotates to rewind the top film 600, and the bottom tape reel 40 rotates to rewind the bottom tape 500. Under the traction force of the drive mechanism 40 and the pushing force of the peeling part 61, each sheet 400 is peeled off from the bottom tape 500 one by one and pushed onto the receiving table 70, which facilitates the assembly mechanism to pick up and deliver the peeled sheet 400. After the mesh 200 on the sheet 400 is attached to the assembly hole of the mobile phone frame, the release paper 300 can be removed. This simple and effective method realizes automatic feeding of the mesh 200, effectively improves peeling accuracy and feeding efficiency, and is suitable for the high-efficiency requirements of automated production lines. It is different from the existing sheet feeding method. On the other hand, after stripping, the sheet material 400 on the receiving table 70 is identified manually or by equipment such as an industrial camera. Qualified products that meet the requirements remain on the receiving table 70, waiting to be removed, while non-qualified sheet material 400 is blown by a blowing mechanism 80 located at the top side of the receiving table 70 to a waste bin 82 located at the front side of the receiving table 70, further ensuring the stripping effect and avoiding subsequent ineffective operations.
