Description

Technical Field

[0001] This invention belongs to the field of material processing technology, and specifically relates to a degumming device and a degumming method. Background Technology

[0002] In recent years, with the rapid development of the smartwatch industry, watch case structures have gradually evolved from traditional single-material designs to diversified composite structures such as aluminum-plastic composites, steel-plastic composites, and cases combined with decorative rings. Among these, the application of combined cases and decorative rings is becoming increasingly widespread, significantly increasing the requirements for processing precision and consistency in the adhesive application and removal processes between the case and the decorative ring. Currently, residual adhesive removal on such parts largely relies on manual handling, which is not only inefficient but also fails to meet the demands of automated mass production for current precision wearable devices. Summary of the Invention

[0003] The purpose of this invention is to at least solve the problem of low automation in existing adhesive removal processes. This purpose is achieved through the following technical solution: A first aspect of the present invention provides an adhesive removal device, comprising: Base; The driving mechanism includes a rotation driving component and a first support base, wherein the first support base is fixedly disposed on the base and the rotation driving component is assembled on the first support base; A fixing mechanism is connected to the rotating drive member, which is configured to drive the fixing mechanism to rotate about its own axis. The fixing mechanism includes a fixing member and two clamping members. The fixing member is connected to the rotating drive member and defines an accommodating space with an opening inside. The two clamping members are both assembled in the accommodating space. The top end of each clamping member extends out of the accommodating space through the opening. The top ends of the two clamping members can open and close relative to each other. The top ends of the two clamping members are used to extend into the inner cavity of the part to be degummed and fix it. The adhesive removal mechanism includes an adhesive removal component and a second support base.

Therefore, the example term "below" can include both upper and lower orientations.

[0020] In recent years, with the rapid development of the smartwatch industry, watch case structures have gradually evolved from traditional single-material designs to diversified composite structures such as aluminum-plastic composites, steel-plastic composites, and cases combined with decorative rings. Among these, the application of combined cases and decorative rings is becoming increasingly widespread, significantly increasing the requirements for processing precision and consistency in the adhesive application and removal processes between the case and the decorative ring. Currently, residual adhesive removal on such parts largely relies on manual handling, which is not only inefficient but also fails to meet the demands of automated mass production for current precision wearable devices.

[0021] Figure 1 A schematic diagram of the overall structure of the adhesive removal device 100 according to an embodiment of the present invention is shown. Figure 3 for Figure 2 A structural schematic diagram of the fixing mechanism 30. (See diagram below.) Figure 1 and 3 As shown, this invention proposes a glue removal device 100 and a glue removal method. The glue removal device 100 of this invention includes a base 10, a drive mechanism 20, a fixing mechanism 30, and a glue removal mechanism 40. The drive mechanism 20 includes a rotation drive member 22 and a first support base 21. The first support base 21 is fixed to the base 10, and the rotation drive member 22 is assembled to the first support base 21. The fixing mechanism 30 is connected to the rotation drive member 22 in a transmission connection. The rotation drive member 22 is configured to drive the fixing mechanism 30 to rotate about its own axial direction. The fixing mechanism 30 includes a fixing member and two clamping members 32. The fixing member is connected to the rotation drive member 22 and internally defines an opening 3131. The receiving space is provided with two clamping members 32, each clamping member 32 having its top end extending out of the receiving space through an opening 3131. The top ends of the two clamping members 32 can open and close relative to each other. The top ends of the two clamping members 32 are used to extend into the inner cavity of the part to be de-adhesive 42 and fix it. The de-adhesive removal mechanism 40 includes a de-adhesive member 42 and a second support base 41. The second support base 41 is fixed to the base 10. The de-adhesive member 42 is assembled on the second support base 41 and located at the top of the fixing mechanism 30. The de-adhesive member 42 is configured to move toward the fixing mechanism 30 to scrape off the adhesive on the part to be de-adhesive 42.

[0022] By using the adhesive removal device 100 in this technical solution, the base 10 integrates the drive mechanism 20, the fixing mechanism 30, and the adhesive removal mechanism 40, resulting in a compact overall structure. The fixing mechanism 30 includes two sets of clamping members 32 that can be opened and closed relative to each other. By extending the top of the clamping member 32 into the inner cavity of the part to be adhesive removed 42, stable clamping can be achieved, effectively preventing the workpiece to be adhesive removed from shaking or shifting during the adhesive removal process. Relying on the rotating drive member 22, the fixing mechanism 30 and the part to be adhesive removed 42 can be driven to rotate axially as a whole. In conjunction with the adhesive removal member 42 that can move toward the fixing mechanism 30, a circumferential relative scraping motion is formed, which can continuously complete the adhesive removal of the workpiece to be adhesive removed. The entire process of the adhesive removal device 100 of this invention can be executed continuously and automatically, reducing manual intervention, effectively improving the automation level of the device, and shortening the loading, unloading, and adhesive removal operation time, thus significantly improving the efficiency of automated adhesive removal operation.

[0023] Specifically, in this embodiment, the two clamping members 32 can be relatively close or far apart. When the two clamping members 32 are relatively close, the outer contour dimension of the top of the clamping member 32 shrinks, making it easier to fit the inner cavity of the workpiece to be degummed onto the outside of the top of the clamping member 32. After the workpiece is in place, the two clamping members 32 open away from each other, and the outer side of the top of the clamping member 32 presses against the inner wall of the inner cavity of the workpiece to be degummed, achieving stable clamping and positioning of the workpiece to be degummed through internal support.

[0024] Specifically, in this embodiment, such as Figure 1 As shown, a start switch is installed on the base 10, which is electrically connected to the drive mechanism 20, the adhesive removal mechanism 40, and the drive component 38, respectively. The operation of the equipment is controlled by energizing and de-energizing. The adhesive removal component 42 is a scraper that can scrape, clean, remove excess material, or apply a coating to the surface of the workpiece to be removed, keeping the surface clean and completing the physical separation. The rotation drive component 22 is a motor that precisely controls the speed, torque, and direction of movement, providing the power for rotational motion.

[0025] In some embodiments of the present invention, such as Figure 3 and 4 As shown, the fixing component includes a connecting part 311, a base part 312, and a housing part 313. The connecting part 311 is connected to the rotation drive member 22. The housing part 313 is fixedly mounted on the connecting part 311. A mounting groove is formed on the side of the housing part 313 facing the connecting part 311. The base part 312 is disposed in the mounting groove and fixedly connected to the connecting part 311. The base part 312 and the housing part 313 together form an accommodating space. An opening 3131 is formed in the housing part 313. The bottom ends of the two clamping members 32 are respectively hinged to opposite sides of the base part 312. Each clamping member 32 can rotate around its own bottom end to achieve relative proximity or distance between the top ends of the two clamping members 32. In this embodiment, the connecting part 311 serves as a reference for docking with the rotation drive member 22, which can stably transmit rotational power and ensure the coaxiality and smooth operation of the overall rotational transmission. Both the base portion 312 and the housing portion 313 are connected to the connecting portion 311, enabling them to rotate synchronously with the rotating drive component 22 via the connecting portion 311. The base portion 312 is embedded in the mounting groove of the housing portion 313 and fixed to the connecting portion 311, achieving precise positioning and fixation through the limiting fit of the groove. The base 10 is provided with a mounting hole, and the connecting portion 311 is located within the mounting hole and connected to the inner wall surface of the mounting hole via a bearing.

[0026] The base portion 312 and the housing portion 313 together form a closed receiving space, which houses the hinged motion structure of the clamping member 32 inside. Only the top of the clamping member 32 extends out from the opening 3131 of the housing portion 313, making the overall layout more compact.

[0027] Specifically, in this embodiment, the opening 3131 includes a first opening 3131 and a second opening 3131. The tops of the two clamping members 32 extend out of the receiving space through the first opening 3131 and the second opening 3131, respectively. The openings 3131 can respectively form lateral limiting constraints on the corresponding clamping members 32, restricting the lateral swaying of the clamping members 32 during opening and closing rotation, and ensuring the stability of the movement trajectory of the top of the clamping members 32. At the same time, the two clamping members 32 independently pass through different openings 3131, which can avoid mutual interference when the clamping members 32 rotate. In addition, the independent openings 3131 facilitate the limitation of the maximum swing amplitude of the clamping members 32, prevent the clamping members 32 from excessive rotation, and stably control the clamping stroke.

[0028] Specifically, a coupling 23 is provided between the connecting part 311 and the rotating drive component 22, which can compensate for errors, absorb shocks, and protect the equipment while transmitting power.

[0029] In other embodiments of the present invention, the two clamping members 32 may also be configured as an integral relative opening and closing structure, that is, the two clamping members 32 are relatively close to or far apart in a straight line relative to the whole. In the above embodiments, the two clamping members 32 are rotated around their respective bottom ends. Both of these embodiments can make the top ends of the two clamping members 32 open and close relative to each other, thereby achieving the clamping and fixing of the workpiece to be degummed.

[0030] In some embodiments of the present invention, such as Figure 3 and 4 As shown, the fixing mechanism 30 also includes two pushing members 33. One end of each pushing member 33 passes through the housing portion 313 and abuts against the middle of the corresponding clamping member 32. The pushing member 33 can drive the corresponding clamping member 32 to rotate around its own bottom end. In this embodiment, the lever effect enables the effective opening and closing of the top of the clamping member 32 with a small pushing stroke, improving the response speed of the clamping action. The force applied to the middle of the clamping member 32 can reasonably distribute the load borne by the hinge fulcrum and reduce wear and deformation of the hinge part. Furthermore, the pushing members 33 drive the clamping members 32 one-to-one, which facilitates the synchronous control of the clamping actions on both sides, effectively preventing clamping deviation caused by uneven force. The housing portion 313 can also guide and limit the pushing members 33, ensuring that the pushing members 33 push linearly, the action is smooth and reliable, and the workpiece clamping and positioning accuracy is continuously maintained.

[0031] Specifically, in this embodiment, along the arrangement direction of the two clamping members 32, the housing portion 313 is provided with a first through hole and a second through hole, which are respectively connected to the accommodating space. The two pushing members 33 are respectively inserted through the first through hole and the second through hole, and can respectively abut against the middle of the two clamping members 32.

[0032] Furthermore, such as Figure 4As shown, the pushing member 33 is equipped with a roller 333 facing the corresponding clamping member 32. The roller 333 can rotate around its own axis, and the roller 333 and the corresponding clamping member 32 roll in contact. Compared with direct sliding contact, this can significantly reduce the frictional resistance between the two during relative movement and reduce the power loss during the pushing process of the pushing member 33. At the same time, it can effectively avoid wear and scratches on the contact surface under long-term reciprocating motion, and extend the service life of the parts. Furthermore, the rolling contact can effectively prevent jamming between the pushing member 33 and the clamping member 32, ensuring smooth and stable opening and closing of the clamping member 32.

[0033] In some embodiments of the present invention, such as Figure 3 and 4 As shown, the fixing mechanism 30 also includes two driving components 38. The two driving components 38 are respectively connected to the base 10 and are disposed on opposite sides of the fixing mechanism 30. Each of the two driving components 38 corresponds to one of the two pushing members 33. The driving components 38 are configured to move toward the corresponding pushing member 33, so that the pushing member 33 drives the corresponding clamping member 32 to rotate. In this embodiment, the two sets of driving components 38 are independently arranged on opposite sides of the fixing mechanism 30 and drive the pushing members 33 one-to-one. The driving paths on both sides are independent, facilitating synchronous control of the pushing force on both sides. This ensures that the opening and closing actions of the two clamping members 32 are coordinated and consistent, effectively avoiding the problem of uneven clamping force on the workpiece to be degummed caused by differences in driving force on one side.

[0034] The drive component 38, pusher 33, and clamping component 32 form a one-to-one independent transmission branch, with a clear and direct force transmission path. The symmetrical layout on both sides can balance the lateral forces generated during operation, reduce the radial load on the rotating drive component 22, and improve the overall rotational stability, making it suitable for long-term continuous automated degumming operations.

[0035] Specifically, in this embodiment, the driving component 38 can be a cylinder or other driving component 38, or it can be an electric push rod, linear motor, electromagnet or other driving component that can achieve linear reciprocating motion, and is not limited to a cylinder.

[0036] In some embodiments of the present invention, such as Figure 4As shown, the pushing member 33 includes a connected abutment portion 331 and a pushing portion 332. The abutment portion 331 can abut against the driving member 38, and the pushing portion 332 passes through the housing portion 313 and abuts against the middle of the corresponding clamping member 32. A first elastic member 35 is provided between the abutment portion 331 and the housing portion 313. The first elastic member 35 is configured to provide a restoring elastic force for the pushing member 33. In this embodiment, the pushing member 33 is divided into an interconnected abutment portion 331 and a pushing portion 332. The driving member 38 realizes power input through the abutment portion 331, and the pushing portion 332 passes through the housing portion 313 to drive the clamping member 32 to rotate. The power transmission hierarchy is clear and reliable.

[0037] Furthermore, a first elastic element 35 is provided between the abutment portion 331 and the housing portion 313. When the driving component 38 retracts and releases the pressure on the abutment portion 331, the first elastic element 35 can automatically reset the entire pushing component 33 using its own elastic force, eliminating the need for an additional reset drive structure. Simultaneously, the first elastic element 35 continuously applies preload to the pushing component 33, ensuring that the rollers 333 on the pushing component 33 always remain in contact with the surface of the clamping component 32, eliminating the lag caused by the fit gap and improving the consistency of the clamping action response. Moreover, the elastic buffering effect of the first elastic element 35 can absorb the impact load generated by the driving component 38's push, reducing collision wear between the pushing component 33 and the clamping component 32, and extending the service life of the components. In addition, the automatic return of the pushing component 33 by the first elastic element 35 allows the driving component 38 to complete the clamping and releasing control of the clamping component 32 with only a unidirectional push force, facilitating automated and orderly loading and unloading operations.

[0038] Specifically, in this embodiment, such as Figure 4 As shown, along the arrangement direction of the two clamping members 32, two mating holes are respectively provided on opposite sides of the housing part 313. The fixing mechanism 30 also includes two guide members 34. One end of each guide member 34 passes through the abutment part 331 of a pusher member 33 and extends into a mating hole. Two first elastic members 35 are provided. The first elastic members 35 are sleeved on the outside of one guide member 34 and abut against the bottom wall of one abutment part 331 and one mating hole, respectively. The guide member 34 passes through the abutment part 331 of the pusher member 33 and extends into the mating hole. The guide member 34 plays a radial limiting and guiding role for the pusher member 33, constraining the pusher member 33 to only reciprocate along the axial direction of the guide member 34, effectively preventing the pusher member 33 from deviating or tilting during the pushing process, and ensuring that the thrust is accurately applied to the middle of the clamping member 32.

[0039] In addition, the first elastic element 35 is sleeved outside the guide element 34. The guide element 34 can limit the lateral twisting and disengagement of the first elastic element 35, ensuring that the elastic force is output stably along a straight line and preventing the first elastic element 35 from becoming unstable under pressure. The mating structure between the guide element 34 and the mating hole can limit the maximum forward stroke of the pusher 33, playing a mechanical limiting role and preventing the pusher 33 from pushing too hard and causing the clamping element 32 to swing over its range.

[0040] Specifically, in this embodiment, four guide members 34 and four mating holes may be provided, as well as four first elastic members 35. Each guide member 34 passes through one mating hole, and one first elastic member 35 is sleeved on the outside of one guide member 34. The two guide members 34 / first elastic members 35 are symmetrically arranged about the pushing part 332.

[0041] In some embodiments of the present invention, such as Figure 5 As shown, two limiting grooves 3121 are provided on opposite sides of the seat portion 312. Two clamping members 32 are correspondingly disposed in the two limiting grooves 3121. The limiting grooves 3121 have a first side wall, a second side wall, and a third side wall connected in sequence. An opening 3131 is formed between the first side wall and the third side wall. The pushing member 33 abuts against the middle of the corresponding clamping member 32 through the opening 3131. The bottom end of the clamping member 32 is hinged to the first side wall and the third side wall respectively. Along the arrangement direction intersecting the two clamping members 32, the two sides of the clamping member 32 are respectively fitted to the first side wall and the second side wall. In this embodiment, the first side wall and the third side wall of the limiting groove 3121 can form a lateral constraint on the clamping member 32, restricting the clamping member 32 from lateral swinging during opening and closing, stabilizing the motion plane of the clamping member 32, avoiding left and right deviation when subjected to force, and ensuring that the clamping member 32 rotates only along the set trajectory.

[0042] Meanwhile, the sidewall of the limiting groove 3121 can mechanically limit the maximum rotation angle of the clamping member 32, preventing the clamping member 32 from opening or closing excessively, stabilizing the clamping stroke, and ensuring that the radial displacement of the top of the clamping member 32 remains consistent each time it is clamped. In addition, the open opening 3131 is specially reserved for the action channel of the pusher 33, which can accurately limit the action area of ​​the pusher 33, so that the driving force is stably applied to the preset position of the clamping member 32, the force condition is controllable, and it is beneficial to extend the service life of the parts.

[0043] Specifically, such as Figure 4 As shown, the clamping member 32 is hinged to the first side wall and the third side wall via a pin 37.

[0044] In some embodiments of the present invention, such as Figure 4As shown, a second elastic element 36 is provided between the middle of each clamping member 32 and the seat portion 312. The second elastic element 36 is configured to provide a restoring elastic force to the clamping member 32. In this embodiment, when the pushing member 33 releases the pushing force, the second elastic element 36 can provide a restoring elastic force to the clamping member 32 in the opening direction, so that the clamping member 32 maintains its initial open state with its top ends far apart when no external force is applied. When the pushing member 33 pushes forward against the middle of the clamping member 32, the clamping member 32 rotates against the elastic force of the second elastic element 36, and its top ends converge to reduce its outer diameter, making it easier to fit the inner cavity of the workpiece to be degummed onto the outside of the clamping member 32.

[0045] After the drive component 38 retracts and the pusher 33 releases its pushing force, the second elastic element 36 drives the clamping element 32 to quickly reset and open, causing the top of the clamping element 32 to press against the inner wall of the workpiece to be de-adhesive-removed, achieving stable positioning of the workpiece by relying on the supporting force. The second elastic element 36 can eliminate the fit clearance of the hinge pair, reduce action lag, and improve the consistency of the opening and closing action response. At the same time, the elastic force continuously and stably applies supporting force when clamping the workpiece, providing a certain degree of flexible buffering effect and avoiding damage to the workpiece to be de-adhesive-removed caused by rigid clamping. The second elastic element 36 and the first elastic element 35 on the pusher 33 side cooperate with each other to form two independent reset structures, reducing the risk of fatigue failure of a single elastic element and ensuring the continuous and stable operation of automated loading, unloading, and clamping operations.

[0046] In some embodiments of the present invention, such as Figure 2 As shown, the adhesive removal device 100 also includes a detection mechanism, which includes a photoelectric sensor 11 and a connector. The drive mechanism 20 also includes a light-shielding member 24, which is connected to the fixing member and can rotate with the fixing member. The light-shielding member 24 is configured to block the photoelectric sensor 11 as the fixing member rotates. In this embodiment, when the light-shielding member 24 rotates with the fixing member to the sensing area of ​​the photoelectric sensor 11, it will block the photoelectric sensor 11, thereby identifying the reference rotation position of the fixing mechanism 30. This structure can obtain the rotation origin signal of the fixing member, realize the zero-angle positioning of the rotation angle, facilitate the control system to accurately control the rotation angle of the watch case workpiece, and ensure that the adhesive removal operation position is accurate and controllable.

[0047] As a signal triggering element in a sensor system, a light-blocking plate converts mechanical position or motion state into electrical signals through precise physical blocking actions, enabling functions such as positioning, speed measurement, counting, and limit switching. The photoelectric sensor 11 converts changes in light into processable electrical signals, achieving non-contact, high-speed, and high-precision detection and control.

[0048] In some embodiments of the present invention, as shown in Figure 6, the adhesive removal mechanism 40 further includes a buffer member 412 and a connecting member 43. The connecting member 43 is slidably connected to the second support base 41 and can move toward the fixing mechanism 30. The adhesive removal member 42 is disposed on the connecting member 43 and can move with the connecting member 43. The buffer member 412 is disposed on the second support base 41 and abuts against the connecting member 43 along the sliding direction of the connecting member 43. In this embodiment, when the adhesive removal member 42 contacts the workpiece to be adhesive removed for adhesive removal, the buffer member 412 can absorb the forward impact of the connecting member 43, allowing the adhesive removal member 42 to flexibly conform to the surface of the workpiece to be adhesive removed, avoiding the rigid and forceful squeezing of the workpiece by the adhesive removal member 42, effectively preventing deformation of the workpiece to be adhesive removed, and reducing the risk of damage to the workpiece's appearance. The sliding fit structure ensures smooth feeding movement of the adhesive removal member 42, and the buffer member 412 continuously provides elastic pre-pressure, making the adhesive removal pressure controllable and stable. Furthermore, the buffer structure is independently integrated on the side of the second support 41, which is convenient for disassembly and replacement. Different stiffness buffer components 412 can be flexibly selected according to different material workpieces, which broadens the application range of the device and continuously ensures the processing quality of automated glue removal.

[0049] Specifically, in this embodiment, such as Figure 6 As shown, the connecting component 43 is also provided with an air nozzle 44, which is positioned toward the fixing mechanism 30 and can achieve cleaning and drying through a controllable compressed air flow.

[0050] Furthermore, in this embodiment, such as Figure 6 As shown, the connecting component 43 is provided with a limiting part 431, and the second support base 41 is provided with a limiting member 411. The side of the limiting part 431 facing the fixing mechanism 30 can abut against the limiting member 411. The limiting part 431 and the limiting member 411 abut against each other to form a mechanical hard limit, which can accurately limit the maximum movement distance of the connecting component 43 toward the fixing mechanism 30, avoid the over-travel of the de-adhesive part 42, and effectively prevent the workpiece from being deformed by pressure or the de-adhesive part 42 from being bumped and damaged.

[0051] Specifically, in this embodiment, the buffer 412 is a hydraulic buffer 412. The hydraulic buffer 412 provides stable and controllable damping and buffering, smoothly absorbing the impact load when the degumming component 42 contacts the workpiece, preventing damage from impact. Furthermore, the hydraulic buffer 412 has excellent vibration reduction effect, reducing the impact of operational vibration on the overall machine positioning accuracy. It also exhibits excellent fatigue resistance, meeting the requirements of long-term continuous operation of automated equipment. The hydraulic buffer 412 is fixedly installed on the second support base 41, with its piston rod end abutting against the connecting component 43, achieving buffering and vibration reduction through hydraulic damping.

[0052] Furthermore, the working process of the adhesive removal device 100 in this invention is as follows: the adhesive removal device 100 is initially in an initial standby state. Under the elastic pre-tightening action of the second elastic member 36, the two clamping members 32 are kept in an open state with their tops far apart. At the same time, the pushing member 33 is kept in a reset state under the action of the first elastic member 35, and the overall mechanism is in a stable initial posture.

[0053] During formal operation, the two drive components 38 move synchronously toward the corresponding pusher 33 and press against the abutment part 331 of the pusher 33, driving the pusher 33 to overcome the elastic force of the first elastic member 35 and slide along the axial direction of the guide member 34. The roller 333 at the end of the pusher 33 rolls and presses against the middle of the clamping member 32, so that the two clamping members 32 overcome the pre-tightening force of the second elastic member 36 and rotate relative to each other around the bottom hinge point. The tops of the two clamping members 32 are relatively closed and the outer diameter is contracted, leaving space for loading. At this time, the workpiece to be degummed can be sleeved on the outside of the two clamping members 32.

[0054] After the workpiece is in place, the drive component 38 retracts to release the pressure limit on the pusher 33. The pusher 33 slides back to its original position under the reset action of the first elastic component 35, releasing the pushing constraint on the clamping component 32. The clamping component 32 automatically opens again under the reset force of the second elastic component 36, so that the top ends of the two clamping components 32 are stably pressed against the inner wall of the workpiece cavity, realizing the internal support fixation and precise positioning of the workpiece.

[0055] After the workpiece is clamped, the rotating drive 22 drives the fixing part to rotate as a whole, which drives the workpiece fixed on the outside of the clamping part 32 to rotate synchronously in the circumferential direction. During the rotation of the fixing part, the light-shielding part 24 rotates synchronously. When the light-shielding part 24 rotates to the position of the photoelectric sensor 11, it blocks the light path of the sensor. The sensor triggers the origin detection signal. The control system completes the zeroing of the workpiece rotation phase and angle calibration based on the signal to ensure that the starting position of the subsequent glue removal operation is accurate and uniform.

[0056] After phase calibration is completed, the adhesive removal mechanism 40 is activated. The connecting component 43 slides towards the workpiece relative to the second support seat 41, driving the adhesive removal component 42 to approach and contact the workpiece surface. At the moment of contact, the connecting component 43 squeezes the hydraulic buffer component 412. The hydraulic damping effect of the hydraulic buffer component 412 absorbs the feeding impact and achieves flexible bonding. At the same time, the hydraulic buffer component 412 stabilizes and maintains a constant buffer pressure, adaptively compensating for workpiece assembly deviations and dimensional errors, so that the adhesive removal component 42 always adheres to the workpiece surface with a constant pressure.

[0057] As the workpiece rotates continuously with the fixing mechanism 30, the adhesive removal component 42 continuously and evenly scrapes away and cleans the residual adhesive on the outer periphery of the workpiece. During the operation, the hydraulic buffer component 412 continuously reduces shock and stabilizes pressure, effectively avoiding workpiece damage caused by rigid extrusion and ensuring the uniformity of adhesive removal and processing stability.

[0058] After the entire circumference of the workpiece has been degummed, the degumming mechanism 40 drives the connecting component 43 to slide back and reset, causing the degumming component 42 to move away from the workpiece and disengage from the processing position. Then, the driving component 38 extends the pressing pusher 33 again, causing the clamping component 32 to retract and release the internal support clamping limit on the workpiece, allowing the degummed workpiece to be removed, completing a single degumming cycle. Subsequent equipment repeats the above process of loading, clamping, positioning, rotating degumming, and resetting unloading to achieve automated continuous degumming of the workpiece.

[0059] The present invention also provides a method for removing adhesive, such as Figure 7 As shown, the above-mentioned adhesive removal device 100 is used for implementation, and the adhesive removal method includes: S10: Drive the two driving components 38 to move toward the corresponding pushing component 33 respectively, and at the same time, the pushing component 33 pushes the corresponding clamping component 32 to rotate around its own bottom end; S20: Align and fit the inner cavity of the workpiece to be degummed onto the top of the two clamping parts 32; S30: Control the two driving components 38 to move away from each other, while the two clamping members 32 move away from each other under the action of their respective second elastic members 36, and complete the clamping and fixing of the workpiece to be degummed; S40: Start the rotation drive 22, and at the same time, the fixing mechanism 30 drives the workpiece to be degummed to rotate; S50: Control the adhesive removal component 42 to move toward the fixing mechanism 30 to scrape off the adhesive inside the workpiece to be removed.

[0060] The adhesive removal method of this invention is implemented based on the aforementioned adhesive removal device 100. The drive component 38 pushes the pusher 33 to retract the clamping component 32, facilitating convenient loading. After the driving force is removed, the second elastic component 36 automatically opens to complete the internal support positioning of the workpiece. The clamping action is stable, smooth, and highly accurate. The workpiece rotation phase is calibrated by the origin detection of the light-shielding component 24 and the photoelectric sensor 11, ensuring consistent starting angles for each adhesive removal operation and effectively improving batch processing consistency. Simultaneously, the hydraulic buffer component 412 enables flexible feeding and contact of the adhesive removal component 42, adaptively compensating for workpiece errors and buffering contact impacts to avoid workpiece damage and uneven adhesive removal. The mechanical limiting protection of the limiting part 431 and the limiting component 411 further eliminates the risk of overfeeding. The entire method relies on the synergistic cooperation of double elastic reset, low-friction rolling drive, precise alignment, and flexible adhesive removal, resulting in a low failure rate, good operational stability, significantly improving adhesive removal quality and operational efficiency, and is suitable for automated continuous batch adhesive removal production.

[0061] Furthermore, in this embodiment, the adhesive removal method further includes: S60: After the adhesive removal is completed, control the rotation drive 22 to drive the fixing mechanism 30 to rotate back to the initial origin position; S70: Drive the two drive members 38 again to push the corresponding push members 33, so that the top ends of the two clamping members 32 are brought together and the processed workpiece to be degummed is taken out.

[0062] Adding a step to return to the origin after degumming and then unload the workpiece ensures that the fixing mechanism 30 and the workpiece are uniformly reset to the reference posture after each processing cycle, eliminating the cumulative angular deviation from multiple rotations and ensuring a consistent initial position height for each round of workpiece clamping and degumming. Furthermore, returning to the origin before performing clamping, retraction, and workpiece unloading actions effectively avoids problems such as mechanism interference caused by misaligned unloading, ensuring a smooth and safe unloading process and improving the stability and repeatability of the equipment's continuous automated operation.

[0063] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
