Description

Technical Field

[0001] This invention relates to the field of adhesive removal technology for workpieces, and more specifically, to an automatic adhesive removal system and method. Background Technology

[0002] Magnets are mainly used in various sensors, instruments, electronics, electromechanical, medical, educational, automotive, aerospace, and military technology fields. Depending on the metal composition of the magnet, its magnetic properties vary, thus affecting its applications. Currently, magnets are generally manufactured using powder metallurgy. To improve production efficiency, the manufacturing process typically involves first processing the magnets into long strips, then cutting them into segments according to the required length. To further enhance cutting efficiency, multiple magnets are often stacked and cut simultaneously. During stacking, adhesive is applied to adjacent magnets to prevent misalignment during cutting. However, this method also introduces a problem: adhesive residue remains on the outer wall of the cut magnets, necessitating adhesive removal after cutting.

[0003] The applicant has previously developed an automatic adhesive removal machine and applied for patent CN218655899U. This machine features a fixed frame on the machine frame, within which is a roller. The roller holds magnetic workpieces and polishing particles such as quartz sand and high-alumina magnets. The roller can rotate along its axis, and this rotation, combined with a heating element inside the roller, allows for simultaneous rotation and heating, ensuring the magnets are heated thoroughly and evenly, guaranteeing rapid and complete melting of the adhesive on their outer walls. Furthermore, the fixed frame can rotate at any angle relative to the machine frame, perpendicular to the roller's axis, allowing for tilting of the roller. This facilitates loading and unloading while preventing excessive collisions and chipping of the magnets during tumbling. In the adhesive removal machine structure of this patent application, the angle adjustment of the inner frame relies on a servo motor for direct drive. Because the adhesive removal cylinder carries the workpieces and polishing particles during use, its overall weight is large, resulting in a heavy load on the motor. This leads to unstable operation when driving the entire inner frame and adhesive removal cylinder, and a short service life.

[0004] The aforementioned automatic glue removal machine achieves automatic glue removal, saving labor and boasting high efficiency. However, how to add the workpiece and polishing particles into the drum, and how to remove them after glue removal, presents new problems. Current technology typically involves manually feeding the workpiece and polishing particles into the drum separately. After glue removal, the fixed frame is rotated so that the drum's inlet faces downwards, causing the workpiece and polishing particles to be poured out together and collected in a container. The workpiece and polishing particles in the container are then sieved again, and the sieved polishing particles are recycled back into the drum. This operation method requires a large amount of labor and involves numerous steps, resulting in low efficiency.

[0005] In addition, existing automatic glue removal machines have many shortcomings, resulting in low continuity of glue removal on workpieces during actual use, which affects overall work efficiency. Summary of the Invention

[0006] To overcome at least one of the defects in the prior art, the present invention provides an automatic adhesive removal system and method. The system has a stable structure and operation, simple and efficient loading and unloading, convenient operation, and can better realize continuous adhesive removal of batch workpieces with high work efficiency.

[0007] This invention provides an automatic adhesive removal system: including

[0008] Fixed outer frame,

[0009] A rotating inner frame is provided, on which a glue-removing cylinder with one open end is connected, and a first drive mechanism for driving the glue-removing cylinder to rotate along its axial direction; one end of the rotating inner frame near the opening of the glue-removing cylinder is rotatably connected to the fixed outer frame along a direction perpendicular to the axis of the glue-removing cylinder, and the other end of the rotating inner frame is connected to a pull rope, and the top of the fixed outer frame is connected to a pulley, and the other end of the pull rope passes around the pulley and is wound around a hoisting mechanism inside the fixed outer frame; an end cap and a second drive mechanism for driving the end cap to close or open the opening are also connected to the rotating inner frame.

[0010] The loading and unloading mechanism includes a loading component for conveying workpieces and polishing particles into the degumming cylinder and an unloading component for outputting workpieces and polishing particles from the degumming cylinder. The loading component is connected to a guide plate that can be flipped up and down at one end near the fixed outer frame. When the rotating inner frame rotates to the loading position, the guide plate extends into the degumming cylinder. One end of the unloading component is rotatably connected to the end of the rotating inner frame near the opening along a direction perpendicular to the axis of the degumming cylinder. When the rotating inner frame rotates to the unloading position, one end of the unloading component is located directly below the opening of the degumming cylinder.

[0011] Compared with the prior art, the automatic adhesive removal system of the present invention has the following advantages:

[0012] In the automatic glue removal structure of this invention, the glue removal cylinder is rotatably connected to the fixed outer frame via a rotating inner frame. A winch mechanism drives a pull rope to achieve synchronous rotation of the outer frame and the glue removal cylinder, enabling accurate and efficient adjustment of the loading, working, and unloading positions. Furthermore, the winch mechanism, pull rope, and pulleys work together to withstand better loads. On the other hand, the loading and unloading mechanism enables automatic loading and unloading of workpieces and polishing particles without manual intervention, saving labor and improving work efficiency. A guide plate with anti-rotation features is installed at the discharge end of the loading assembly. When loading workpieces, the guide plate guides the workpieces to slide down into the drum instead of dropping directly from a certain height, effectively reducing the risk of chipping during loading and ensuring workpiece integrity.

[0013] Furthermore, it also includes an exhaust gas treatment mechanism, which includes a first blower connected to the top of the fixed outer frame and a cooling box placed on the ground or connected to the fixed outer frame. The air inlet of the blower is connected to the end cap through an air inlet pipe and communicates with the inner cavity of the adhesive remover. The air outlet of the blower is connected to the cooling box through an air outlet pipe, and the air outlet pipe extends below the coolant level in the inner cavity of the cooling box.

[0014] Furthermore, the cooling box includes a first box and a second box that are independent of each other, and the opening end of the first box is connected to a filter chamber. The bottom of the filter chamber is connected to a first filter cotton. The end of the air outlet pipe away from the fixed outer frame passes through the top of the filter chamber and is inserted into the first filter cotton. An exhaust channel is provided on the top and / or side wall of the filter chamber.

[0015] As an improvement, the top of the filter chamber is detachably connected to a cover plate, the cover plate has multiple exhaust holes, and the middle of the cover plate is connected to a positioning tube for the air outlet pipe to pass through; the lower end of the cover plate is provided with a second filter cotton that can cover each of the exhaust holes.

[0016] In a further improvement, a Freon compressor is installed in the second housing, and a cooling coil is installed in the first housing, with both ends of the cooling coil connected to the outlet and inlet of the Freon compressor, respectively.

[0017] Furthermore, the loading and unloading mechanism includes a housing with an opening at the top. The other end of the loading component is rotatably connected to the end of the housing opening away from the degumming cylinder. The loading component is equipped with a screening component for separating the workpiece from the polishing particles. The screened polishing particles fall into the housing, and the screened workpiece continues to be conveyed to the next station. Above the loading component, there is also an air outlet component for blowing air toward the screening component.

[0018] Furthermore, the air outlet assembly includes an air knife and a second blower, the second blower being connected to the chassis; the unloading assembly is provided with a mounting base, the loading assembly is located above the unloading assembly and is slidably connected to the mounting base along its length, the air knife is connected to the mounting base and located below the loading assembly, and the air knife is connected to the second blower through an air duct.

[0019] In the modified machine, a screw feeder is also connected to the chassis. The inlet of the screw feeder is connected to the inner cavity of the chassis, and the outlet of the screw feeder extends to the top of the feeding assembly, for conveying the polishing particles in the chassis to the feeding assembly.

[0020] On the other hand, the present invention also provides a method for removing adhesive based on the above-mentioned automatic adhesive removal system, which mainly includes the following steps:

[0021] S1: The rotating inner frame is adjusted to the preset feeding position by the hoisting mechanism, the end cover is opened by the second drive mechanism, the feeding component slides towards the glue removal cylinder to the set position, the guide plate extends into the glue removal cylinder and flips down to abut against the inner wall of the glue removal cylinder;

[0022] S2: Place the polishing particles and the workpiece onto the feeding assembly in sequence. The feeding assembly automatically conveys the polishing particles and the workpiece into the degumming cylinder. The guide plate and the feeding assembly are reset, and the end cover is closed.

[0023] S3: Rotate the inner frame to the working position. The first drive mechanism drives the degumming cylinder to rotate at a speed of 8 to 15 revolutions per minute. The heating component inside the degumming cylinder is turned on, raising the temperature to 280°C to 320°C.

[0024] S4: After the degumming cylinder has been rotating for 0.5 to 1 hour, stop rotating and heating; before opening the end cover, run the first blower to discharge the mixed waste gas in the degumming cylinder into the cooling box for cooling and odor adsorption.

[0025] S5: The hoisting mechanism drives the inner frame to rotate to the unloading position, opens the end cover, and the degummed workpiece and polishing particles enter the unloading assembly. The screen conveyor belt of the unloading assembly runs, driving the workpiece and polishing particles to be conveyed downwards, and the two are separated during the conveying process.

[0026] S6: During the operation of the screen conveyor belt, the second blower is turned on, and the air knife blows air towards the screen conveyor belt to accelerate the separation of the workpiece and the polishing particles; the separated polishing particles fall into the machine box, and the separated workpiece leaves the screen conveyor belt and enters the transfer box or is directly conveyed to the next station.

[0027] S7: After the workpiece is discharged from the degumming cylinder, rotate the inner frame to reset to the feeding position. The feeding assembly and the guide plate move to the working position again. The polishing particles in the machine box are conveyed to the feeding assembly by the screw feeder and enter the degumming cylinder again. The next batch of workpieces is placed on the feeding assembly and enters the degumming cylinder with it. After the feeding is completed, close the end cover.

[0028] S8: Repeat steps S3 to S7 to achieve continuous and uninterrupted degumming of batch workpieces.

[0029] The aforementioned degumming system makes the degumming process for batch workpieces more time-saving and labor-saving, requiring virtually no manual intervention. The entire loading and unloading process is highly automated, and the polishing particles can be reused. Moreover, the recycling process is also carried out with the help of the loading component. The problem of reusing polishing particles is solved by simply adding a screw feeder.

[0030] Other improvements and advantages of the invention will be set forth in the detailed description that follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0041] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0042] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "fixed" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0043] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0044] See Figures 1 to 8 As shown in the figure, this application discloses an automatic adhesive removal system, including...

[0045] Fixed outer frame 1,

[0046] A rotating inner frame 2 is provided, on which a glue-removing cylinder 3 with one open end is connected, along with a first drive mechanism for driving the glue-removing cylinder 3 to rotate along its axis. The glue-removing cylinder 3 is equipped with a corresponding heating component. Specifically, the rotating structure of the glue-removing cylinder 3 involves a fixed frame at one end of the rotating inner frame 2, with one end of the glue-removing cylinder 3 rotatably connected to the fixed frame. A support mechanism for supporting the glue-removing cylinder 3 is also provided at the upper end of the rotating inner frame 2, and the outer wall of the glue-removing cylinder 3 rolls into the support mechanism. This ensures that the glue-removing cylinder 3 is stably supported on the rotating inner frame 2 while also achieving smooth rotation along its axis. This structure is suitable for the applicant's... The existing patent CN218655899U describes this, so it will not be elaborated here. In addition, a transmission gear 25 is connected to one end of the glue removal cylinder 3, and a rotary drive motor 26 is connected to the rotating inner frame 2. A drive gear 27 is connected to its power output end. The drive gear 27 meshes with the transmission gear 25 to realize the rotation drive of the glue removal cylinder 3. In some other embodiments, a universal sprocket or pulley structure is used to drive the glue removal cylinder 3 to rotate along its axis. The glue removal cylinder 3 is heated while rotating, so that the workpiece inside the glue removal cylinder 3 can be fully and evenly heated, ensuring that the glue on the outer wall of the workpiece melts quickly and completely.

[0047] One end of the rotating inner frame 2 near the opening of the adhesive removal cylinder 3 is rotatably connected to the inner wall of the fixed outer frame 1 along a direction perpendicular to the axis of the adhesive removal cylinder 3. The other end of the rotating inner frame 2 is connected to a pull rope 4. A pulley 5 is connected to the top of the fixed outer frame 1. The other end of the pull rope 4 passes over the pulley 5 and is wound around a hoisting mechanism 6 inside the fixed outer frame 1. The hoisting mechanism 6 includes a hoisting motor with a speed reducer, and a hoisting drum is connected to the power output shaft of the hoisting motor. One end of the pull rope 4 is wound around the hoisting drum, and the other end passes over the pulley 5 at the top of the fixed outer frame 1 and is connected to the rotating inner frame 2. Thus, the extension of the free end of the pull rope 4 is achieved through the operation of the hoisting mechanism 6. Shortening the frame allows the inner frame 2 to rotate relative to the outer frame 1, thereby adjusting the position of the opening of the glue removal cylinder 3. This allows for height adjustment of the glue removal cylinder 3 in the loading, working, and unloading positions. Additionally, the inner frame 2 is connected to an end cap 7 and a second drive mechanism 8 for closing or opening the opening of the glue removal cylinder 3. The end cap 7 and the second drive mechanism 8 mentioned here are existing technologies and are described in the applicant's existing patents. For details, please refer to the end cap 7 and the first drive assembly structure disclosed in patent CN218610805U. The existing structure is directly borrowed here and will not be elaborated further.

[0048] See appendix Figure 5 and 6The loading and unloading mechanism includes a loading assembly 9 for conveying workpieces and polishing particles into the degumming cylinder 3, and an unloading assembly 10 for outputting workpieces and polishing particles from the degumming cylinder 3. One end of the loading assembly 9 near the fixed outer frame 1 is connected to a vertically rotating guide plate 11. When the rotating inner frame 2 rotates to the loading position, the guide plate 11 extends into the degumming cylinder 3, and the guide plate 11 is in contact with the inner wall of the opening of the degumming cylinder 3. This guide plate 11 allows the workpiece to move along... The guide plate 11 slowly slides into the degumming cylinder 3 instead of falling directly from the end of the feeding assembly 9 into the degumming cylinder 3, thus avoiding chipping of the workpiece. In addition, one end of the unloading assembly 10 is rotatably connected to the end of the rotating inner frame 2 near the opening along a direction perpendicular to the axis of the degumming cylinder 3. When the rotating inner frame 2 rotates to the unloading position, one end of the unloading assembly 10 is located directly below the opening of the degumming cylinder 3, so that the workpiece and polishing particles in the degumming cylinder 3 can fall smoothly onto the unloading assembly 10.

[0049] For others, see Appendix Figure 1 , 7 In addition to 8, the automatic adhesive removal assembly of this embodiment also includes an exhaust gas treatment mechanism, which includes a first blower 12 connected to the top of the fixed outer frame 1 and a cooling box 13 placed on the ground or connected to the fixed outer frame 1. The air inlet of the blower is connected to the end cover 7 through the air inlet pipe and communicates with the inner cavity of the adhesive removal machine. The air outlet of the blower is connected to the cooling box 13 through the air outlet pipe, and the air outlet pipe extends below the surface of the coolant in the inner cavity of the cooling box 13. When the mixed exhaust gas enters the cooling box 13, it can be cooled down by the cooling water in the cooling box 13. At the same time, some odor removal medium can also be added to the cooling water, because the gas coming out of the adhesive removal cylinder 3 contains volatile substances of adhesive, which have a certain odor and toxicity. Directly discharging it into the atmosphere will pollute the environment and also affect the health of workers.

[0050] For more details, please see the appendix. Figure 8 The cooling box 13 in the above structure includes a first box 14 and a second box 15 that are independent of each other. The opening end of the first box 14 is connected to a filter chamber 16, and the bottom of the filter chamber 16 is connected to a first filter cotton 17. The end of the air outlet pipe away from the fixed outer frame 1 passes through the top of the filter chamber 16 and is inserted into the first filter cotton 17. An exhaust channel is provided on the top and / or side wall of the filter chamber 16. In this structure, the first filter cotton 17 can be used for the first adsorption and purification function, and at the same time, it serves as a limiter at the end of the air outlet pipe, ensuring that its end always extends below the surface of the coolant. Preferably, the first filter cotton 17 is pearl cotton.

[0051] A cover plate 18 is detachably connected to the top of the filter chamber 16. The cover plate 18 has multiple exhaust holes 19, and a positioning tube 20 for the air duct to pass through is connected to the middle of the cover plate 18. A second filter cotton 21 is provided at the lower end of the cover plate 18 to cover each exhaust hole 19. The second filter cotton 21 here realizes the secondary adsorption and purification effect of the cooled gas. Activated carbon adsorption cotton is preferred to better adsorb odors in the gas and reduce toxicity.

[0052] Additionally, in the aforementioned structure, a Freon compressor (not shown in the figure) is installed in the second housing 15, and a cooling coil (not shown in the figure) is installed in the first housing 14. The two ends of the cooling coil are connected to the outlet and inlet of the Freon compressor, respectively. More specifically, a temperature sensor is also installed in the first housing 14 to monitor the water temperature in real time. This temperature sensor is electrically connected to the Freon compressor; that is, when the temperature sensor detects a set water temperature, it transmits a signal to the control switch of the Freon compressor, starting the Freon compressor. Through the repeated circulation of Freon in the cooling pipes, the cooling water in the first housing 14 is cooled.

[0053] Of course, in some other embodiments, an atomizing device (not shown in the figure) can be added inside the first housing 14, and the outlet of the atomizing device is connected to multiple pipes, each pipe being connected to multiple atomizing nozzles. The low-temperature mist gas sprayed by the atomizing nozzles ventilates and cools the working environment around the fixed outer frame 1.

[0054] On the other hand, in this embodiment, see Appendix Figure 5 and 6 The loading and unloading mechanism includes a housing 22 with an opening at the top. The other end of the unloading assembly 10 is rotatably connected to the end of the opening of the housing 22 away from the degumming cylinder 3. The unloading assembly 10 is equipped with a screening component for separating the workpiece from the polishing particles. The screened polishing particles fall into the housing 22, and the screened workpiece continues to be conveyed to the next station. Above the unloading assembly 10, there is also an air outlet assembly for blowing air toward the screening component. Specifically, the air outlet assembly includes an air knife 23 and a second blower, which is connected to the housing 22. The unloading assembly 10 is equipped with a mounting base. The loading assembly 9 is located above the unloading assembly 10 and is slidably connected to the mounting base along its length. The air knife 23 is connected to the mounting base and located below the loading assembly 9. The air knife 23 is connected to the second blower through an air duct.

[0055] More specifically, in the above structure, a screw feeder 24 is also connected to the housing 22. The inlet of the screw feeder 24 communicates with the inner cavity of the housing 22, and the outlet of the screw feeder 24 extends above the feeding assembly 9, used to transport the polishing particles in the housing 22 to the feeding assembly 9. Most of the structure of the upper and lower mechanisms in this structure can be referenced from the content of the applicant's patent application CN117819247A. For example, the specific structure and connection method of the feeding assembly 9, the unloading assembly 10, and the tilting mechanism of the guide plate 11 are clearly described in the application, and will not be elaborated here. Furthermore, the screw feeder 24 involved in this structure is also a conventional existing structure; for details, please refer to the screw feeder 24 structure disclosed in patents CN117819247A or CN213493513U.

[0056] In addition, this application also discloses a method for removing adhesive from the above-mentioned automatic adhesive removal system, which includes the following specific steps:

[0057] S1: First, the rotating inner frame 2 is lifted and adjusted to the preset loading position height by the hoisting mechanism 6. Then, the end cover 7 is opened by the second drive mechanism 8, and the loading component 9 slides towards the de-adhesive cylinder 3 to a set position close to the opening of the de-adhesive cylinder 3. The guide plate 11 extends into the de-adhesive cylinder 3 and flips down to be close to the inner wall of the de-adhesive cylinder 3.

[0058] S2: The polishing particles and workpieces are placed onto the conveyor belt of the feeding assembly 9 in sequence. The polishing particles and workpieces are automatically conveyed to the degumming cylinder 3 through the conveyor belt and the guide plate 11. After the feeding is completed, the guide plate 11 and the feeding assembly 9 are reset and the end cover 7 is closed.

[0059] S3: After the material is fed, the inner frame 2 is rotated and adjusted to the working position by the hoisting mechanism 6. The first drive mechanism drives the degumming cylinder 3 to rotate at a speed of 8 to 15 revolutions per minute. The heating components inside the degumming cylinder 3 are turned on simultaneously to raise the temperature to 280°C to 320°C.

[0060] S4: After the glue removal cylinder 3 has been rotating for 0.5 to 1 hour, stop rotating and heating. After the glue removal is completed, before opening the end cover 7, run the first blower 12 to discharge the mixed waste gas in the glue removal cylinder 3 to the cooling box 13 for cooling and odor adsorption, so as to cool down the heat-insulating hot gas in the glue removal cylinder 3 and then release it into the atmosphere after odor adsorption.

[0061] S5: The inner frame 2 is driven to rotate to the unloading position again by the hoisting mechanism 6, the end cover 7 is opened, the workpiece after degumming and the polishing particles enter the unloading assembly 10, the screen conveyor belt of the unloading assembly 10 runs, driving the workpiece and polishing particles to be conveyed downwards, and the two are separated during the conveying process.

[0062] S6: During the operation of the screen conveyor belt, the second blower is turned on simultaneously, and the air knife 23 blows air towards the screen conveyor belt to accelerate the separation of the workpiece and the polishing particles; and the separated polishing particles fall into the machine box 22, and the separated workpiece leaves the screen conveyor belt and enters the transfer box or is directly conveyed to the next station.

[0063] S7: After the workpiece is discharged from the degumming cylinder 3, the inner frame 2 is rotated back to the feeding position, the feeding assembly 9 and the guide plate 11 move to the working position again, and the polishing particles in the machine box 22 are conveyed back to the feeding assembly 9 through the screw feeder 24 and enter the degumming cylinder 3 again. Then, the next batch of workpieces is placed on the feeding assembly 9 and enters the degumming cylinder 3. After the feeding is completed, the end cover 7 is closed.

[0064] S8: Repeat steps S3 to S7 to achieve continuous and uninterrupted degumming of batch workpieces.
