DETAILED DESCRIPTION

[0033] The core of the present application is to provide a peeling shovel to improve the cleaning efficiency of polishing cloth and its aged adhesive backing.

[0034] Another core of the present application is to provide a peeling method using the above-mentioned peeling shovel.

[0035] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0036] ​​Traditional cleaning of waste polishing cloth and its back adhesive mainly adopts manual method, such as using art knife, shovel knife and other tools for scraping and tearing. This method has many defects: first, the cleaning efficiency is low and the labor intensity is large, which consumes a lot of manpower and time; second, in the polishing process, the back adhesive will age, harden due to high temperature, high pressure and chemical action, and the adhesion with the cloth base becomes very strong, which is difficult to completely remove by manual scraping. The residual adhesive layer will seriously affect the flatness of the new polishing cloth, and then lead to uneven polishing effect, even scratch the wafer, and reduce the product yield; third, the operator is easy to damage the expensive cloth base surface and destroy its flatness when scraping with force. In addition, some auxiliary cleaning methods use chemical solvents, but these solvents not only have poor effect on some seriously aged glue, but also produce volatile organic compounds, pollute the environment and harm the health of the operator.

[0037] Therefore, as shown in Figure 1 The embodiment of the present application discloses a stripping shovel 100, which comprises a shell 10, a shovel head assembly 20, a driving assembly 30 and a blowing assembly 40. The aged adhesive is heated and softened by the hot air generating assembly 42, which can effectively reduce its adhesion. At the same time, the shovel head assembly 20 is driven by the driving assembly 30 to reciprocate, instead of traditional manual scraping. The two work together to significantly improve the cleaning efficiency and reduce the labor intensity of the operator. By softening the adhesive layer and combining with the reciprocating mechanical scraping, the polishing cloth and the back adhesive layer can be completely and thoroughly stripped from the cloth base, avoiding the residue of the adhesive layer, and effectively avoiding the damage to the flatness of the base surface, achieving the purpose of complete cleaning and protecting the base material. In addition, chemical solvents are not needed, which can avoid the generation of harmful gases, and is more friendly to the environment and the operator, improving the environmental protection and safety of the operation, and realizing complete and non-destructive cleaning, ensuring the flatness and firmness of the new polishing cloth bonding, so as to ensure the stability and uniformity of the subsequent polishing process, which helps to improve the yield of the final product.

[0038] The stripping shovel 100 disclosed in the embodiment of the present application will be explained and described in detail below. Figure 1 and Figure 2 The stripping shovel 100 disclosed in the embodiment of the present application will be explained and described in detail below.

[0039] As shown in Figure 1 and Figure 2As shown, the shell 10 can adopt a cylindrical structure, and the shovel head assembly 20 can be movably arranged at one end of the shell 10, and the driving assembly 30 can be arranged in the shell 10 and in transmission connection with the shovel head assembly 20, so that the shovel head assembly 20 can be driven by the driving assembly 30 to reciprocate, and the shovel head assembly 20 can be pushed at the same time, so that the target object can be stripped from the base surface by the shovel head assembly 20. Wherein, the blowing assembly 40 can include a wind guide assembly 41 and a hot air generating assembly 42, and the hot air generating assembly 42 can be arranged in the shell 10 to generate hot air that can soften the colloid, and the hot air generated by the hot air generating assembly 42 can be guided to the adhesion between the target object and the base surface by the wind guide assembly 41, so as to realize the softening of the colloid, so as to facilitate the stripping of the softened colloid and the target object from the base surface by the shovel head assembly 20. It should be noted that in the above embodiment, the target object can be a polishing cloth, and the base surface can be a cloth base on the polishing equipment, and the polishing cloth and the adhesive layer can be completely and completely stripped from the cloth base by the stripping shovel 100, avoiding the residue of the adhesive layer, while effectively avoiding the damage to the flatness of the base surface, achieving the purpose of complete cleaning and protecting the base material. Of course, the target object can also be other bonded objects, such as wallpaper, etc., and the base surface can also adopt other bonding surfaces, such as wall surface, etc., so as to realize the effect of stripping the target object from the base surface by the stripping shovel 100. Hereinafter, the target object refers to the polishing cloth, and the base surface refers to the cloth base on the polishing equipment, unless otherwise specified.

[0040] When the stripping shovel 100 is used to strip the target object, the hot air generated by the hot air generating assembly 42 can be guided to the adhesion between the target object and the base surface by the wind guide assembly 41 of the blowing assembly 40, so that the colloid at the adhesion can be softened, and then the shovel head assembly 20 is driven by the driving assembly 30 to reciprocate and push the shovel head assembly 20, so as to strip the target object and the softened colloid from the base surface,

[0041] The stripping shovel 100 disclosed in the embodiment of the present application can guide the hot air generated by the hot air generating assembly 42 to the adhesion between the target object and the base surface by the wind guide assembly 41 of the blowing assembly 40, so that the colloid at the adhesion can be softened to effectively reduce the adhesion, and the shovel head assembly 20 can be driven by the driving assembly 30 to reciprocate and push the shovel head assembly 20, so as to strip the target object and the softened colloid from the base surface.

[0042] The stripping shovel 100 disclosed by the embodiments of the present application can heat and soften the aging colloid through the hot air generating assembly 42, which can effectively reduce the adhesion, and the driving assembly 30 drives the shovel head assembly 20 to reciprocate, replacing the traditional manual scraping shovel, and the two work together to significantly improve the cleaning efficiency and reduce the labor intensity of the operator. By softening the colloid and combining the reciprocating mechanical scraping, the polishing cloth and the adhesive layer can be completely and thoroughly stripped from the cloth base, avoiding the residue of the adhesive layer, and effectively avoiding the damage to the flatness of the base surface, achieving the purpose of complete cleaning and protecting the base material. In addition, without the use of chemical solvents, harmful gases can be avoided, which is more friendly to the environment and the operator, improves the environmental protection and safety of the operation, and can achieve complete and non-destructive cleaning, ensuring the flatness and firmness of the new polishing cloth bonding, thereby ensuring the stability and uniformity of the subsequent polishing process, which helps to improve the yield of the final product.

[0043] In some embodiments, as shown in Figure 1 and Figure 2 , the air guide assembly 41 can include an air outlet joint 411 and an air guide pipe 412. Wherein the air outlet joint 411 is located at the same end of the shell 10 as the shovel head assembly 20, and the air outlet joint 411 has an air outlet 4111, the shovel head assembly 20 can extend out of the air outlet 4111, and one end of the air guide pipe 412 communicates with the air outlet joint 411, and the hot air generating assembly 42 can be located at the other end of the air guide pipe 412, so that the hot air generated by the hot air generating assembly 42 can be guided by the air guide pipe 412 to the air outlet 4111 of the air outlet joint 411 and blown to the bonding place of the target object and the base surface, thereby heating and softening the colloid.

[0044] In some embodiments, as shown in Figure 1 and Figure 2 , the air outlet joint 411 can have a large-diameter end and a small-diameter end arranged opposite to each other. Wherein the cross-sectional area of the air outlet joint 411 gradually decreases from the large-diameter end of the air outlet joint 411 towards the small-diameter end of the air outlet joint 411, and the large-diameter end of the air outlet joint 411 is connected with the shell 10, and the air outlet 4111 can adopt a flat mouth structure, so as to provide a moving space for the reciprocating movement of the shovel head assembly 20. In addition, the air guide pipe 412 can adopt one, or two or more, to increase the air outlet amount of the hot air and ensure the softening efficiency of the colloid. At least part of the small-diameter end of the air outlet joint 411 can be the air outlet 4111, that is, the small-diameter end of the air outlet joint 411 can be partially arranged as the air outlet 4111, and the remaining part is a closed area, so that the hot air can be concentrated and sent out from the air outlet 4111, improving the softening efficiency of the colloid. Of course, the small-diameter end of the air outlet joint 411 can also be completely arranged as the air outlet 4111, so that the area of the air outlet 4111 of the hot air can be increased, ensuring the uniformity of the hot air blowing, thereby achieving uniform softening of the colloid.

[0045] In some embodiments, the air outlet 4111 can be arranged centrally relative to the housing 10. Of course, as shown in Figure 1 and Figure 2 , the air outlet 4111 can also be arranged eccentrically relative to the housing 10 in a direction away from the base surface, and the shovel head assembly 20 can be extended from the air outlet 4111, i.e., the shovel head assembly 20 can be arranged eccentrically relative to the housing 10 in a direction away from the base surface. For the convenience of understanding, the surface connecting the air outlet joint 411 with the upper edge of the air outlet 4111 is defined as the air outlet upper surface, the surface connecting the air outlet joint 411 with the lower edge of the air outlet 4111 is defined as the air outlet lower surface, and the angle between the air outlet upper surface and the base surface is greater than the angle between the air outlet lower surface and the base surface, so that the working angle adjustment range of the stripping shovel 100 can be larger, the needs of different scenes can be met, and the hot air can be blown more uniformly to the bonding part of the target object and the base surface, so as to ensure the uniformity of the softened adhesive.

[0046] In some embodiments, as shown in Figure 1 and Figure 2 , the stripping shovel 100 can further include a holding portion 50 for facilitating pushing of the shovel head assembly 20, and the holding portion 50 can be connected to one end of the housing 10 away from the shovel head assembly 20 through a connecting portion 51, so that an operator can grasp the holding portion 50 to push the shovel head assembly 20 to strip the target object and the softened adhesive from the base surface. At the same time, the holding portion 50 and the housing 10 are provided with a heat insulation layer, so as to ensure the safety of operation.

[0047] In some embodiments, as shown in Figure 1 , the connecting portion 51 can have oppositely arranged large-diameter and small-diameter ends, and the cross-sectional area of the connecting portion 51 gradually decreases from the large-diameter end of the connecting portion 51 toward the small-diameter end of the connecting portion 51. The large-diameter end of the connecting portion 51 can be connected to the housing 10, and the small-diameter end of the connecting portion 51 can be connected to the holding portion 50.

[0048] In some embodiments, the holding portion 50 can be arranged centrally relative to the housing 10. Of course, as shown in Figure 1 , the holding portion 50 can also be arranged eccentrically relative to the housing 10 in a direction away from the base surface, i.e., the eccentric direction of the holding portion 50 is opposite to the eccentric direction of the air outlet 4111, so as to ensure that the operator has a larger holding space to adapt to the adjustment of the working angle of the stripping shovel 100, and meet the use needs of different scenes.

[0049] In some embodiments, as shown in Figure 2As shown, the hot air generating assembly 42 can include a fan 421 and a heating element 422. Among them, the fan 421 can be matched with the air guide pipe 412, that is, one end of each air guide pipe 412 can be provided with a fan 421 to generate air flow to the air guide pipe 412 through the fan 421. At the same time, a heating cabin can be independently arranged in the shell 10, and the heating element 422 can be located in the heating cabin, and the air guide pipe 412 can be communicated with the heating cabin through the fan 421, so that the fan 421 can guide the hot air in the heating cabin to the air guide pipe 412 and blow it to the target object and the bonding surface of the target object, so as to soften the glue.

[0050] In the above embodiment, the heating element 422 can adopt a plurality of electric heating pipes, and each electric heating pipe can be fixed in the heating cabin through the base, and the fan 421 can adopt a centrifugal fan, so that the air flow generated by the centrifugal fan can be heated by each electric heating pipe.

[0051] In some embodiments, the fan 421 adopts a centrifugal fan, and the fan 421 can be arranged near the air inlet inside the shell 10, which can suck the ambient air from the outside of the stripping spade 100 and pressurize when the fan 421 rotates, forming a stable air flow, and the heating element 422 can be arranged on the air outlet path of the fan 421 to heat the air flowing through. The heating element 422 can adopt a thermistor ceramic heater, which has the characteristics of rapid temperature rise, self-controlled constant temperature, high heat conversion efficiency and good safety, or the heating element 422 can also adopt a traditional resistance wire heater and cooperate with a temperature sensor to accurately control the temperature.

[0052] In some embodiments, as shown, Figure 2 The driving assembly 30 can include a driving motor 31, a transmission mechanism 32 and a translation guide rail 33. Among them, the spade head assembly 20 can be slidably arranged on the translation guide rail 33, and the driving motor 31 can be connected with the spade head assembly 20 through the transmission mechanism 32, so as to convert the rotary motion of the driving motor 31 into the reciprocating motion of the spade head assembly 20 through the transmission mechanism 32, so as to realize the rapid stripping of the target object through the reciprocating motion of the spade head assembly 20.

[0053] In some embodiments, the driving motor 31 can be a high-torque DC brushless motor, and an eccentric wheel can be fixed on the output shaft of the driving motor 31. Meanwhile, the transmission mechanism 32 can include a connecting rod matched with the eccentric wheel, one end of the connecting rod being connected with the eccentric wheel of the driving motor 31, and the other end of the connecting rod being connected with the spade head assembly 20. When the driving motor 31 rotates, the eccentric wheel drives the connecting rod to accurately convert the rotary motion into the linear reciprocating motion of the spade head assembly 20 on the translation rail 33. The frequency of the reciprocating motion of the spade head assembly 20 can be adjusted according to the rotating speed of the driving motor 31, so that the high-frequency reciprocating scraping action of the spade head assembly 20 can significantly reduce the manual pushing force required for single scraping and effectively overcome the strong bonding force of the aged back adhesive. It should be noted that the driving motor 31 can also realize the reciprocating motion of the spade head assembly 20 on the translation rail 33 through a crank connecting rod mechanism, that is, a crank can be fixed on the output shaft of the driving motor 31, and the transmission mechanism 32 can include a connecting rod matched with the crank, one end of the connecting rod being connected with the crank of the driving motor 31, and the other end of the connecting rod being connected with the spade head assembly 20. When the driving motor 31 rotates, the crank can drive the connecting rod to accurately convert the rotary motion into the linear reciprocating motion of the spade head assembly 20 on the translation rail 33.

[0054] In some embodiments, the driving assembly 30 can also be directly composed of a linear electromagnetic push rod, rather than the combination of the driving motor 31 and the transmission mechanism 32. The linear electromagnetic push rod is an actuator that directly converts electrical energy into linear motion, which can include an electromagnetic coil and a movable iron core push rod inside. The fixed shell of the linear electromagnetic push rod is firmly installed inside the shell 10 of the stripping spade 100, and the output end of the telescopic iron core push rod can be directly or through a connecting piece rigidly connected with the spade head assembly 20. The spade head assembly 20 can also be slidably installed on the translation rail 33 to ensure the stability of the reciprocating motion of the spade head assembly 20.

[0055] In some embodiments, as shown in Figure 1 and Figure 2 The spade head assembly 20 can include a spade head 21 and a connecting seat 22. The spade head 21 can be made of materials with high temperature resistance, wear resistance and low friction coefficient, such as Teflon coated metal, ceramic or special engineering plastic, and the end of the spade head 21 can be provided with a blade to achieve the effect of quickly stripping the target object and the base surface. The spade head 21 can be drivingly connected with the driving assembly 30 through the connecting seat 22, so that the driving assembly 30 can drive the spade head 21 to reciprocate through the connecting seat 22, thereby achieving the quick stripping of the target object. Meanwhile, the spade head 21 and the connecting seat 22 can be fixed by detachable connection modes such as plug-in connection, clamping connection or bolt connection, so as to replace the spade head 21.

[0056] In some embodiments, as shown in Figure 1 andFigure 2 As shown, the shoveling head 21 is connected with the connecting seat 22, and the shoveling head 21 and the connecting seat 22 can be locked and fixed through the shoveling head lock 23 which can be quickly released. The shoveling head lock 23 can be a knob lock, so that the shoveling head 21 and the connecting seat 22 can be quickly locked or released by rotating the knob lock.

[0057] In some embodiments, the connecting seat 22 can be provided with a sliding groove, and the shoveling head 21 can be provided with a protruding part capable of sliding into the sliding groove. One or more first mounting holes can be provided on the connecting seat 22, and the first mounting holes can be located on the groove wall of the sliding groove. The protruding part of the shoveling head 21 can be provided with a second mounting hole matched with the first mounting hole, so that a fastener such as a bolt can pass through the first mounting hole and the second mounting hole and be locked and fixed by a locking nut. The sliding groove can be a T-shaped groove, a C-shaped groove or a dovetail groove, and the protruding part can have a T-shaped cross section, a C-shaped cross section or a dovetail-shaped cross section matched with the sliding groove, so that the protruding part of the shoveling head 21 can slide into the sliding groove of the connecting seat 22, thereby limiting the rotation of the shoveling head 21. Of course, the connecting seat 22 can also be provided with a protruding part, and the shoveling head 21 can be provided with a sliding groove, so that the protruding part on the connecting seat 22 can slide into the sliding groove of the shoveling head 21, which is not limited herein.

[0058] In some embodiments, a stop part can be provided in the sliding groove to limit the sliding of the protruding part, prevent the protruding part from sliding out of the sliding groove, and ensure that the first mounting hole and the second mounting hole are quickly centered, thereby achieving quick installation between the connecting seat 22 and the shoveling head 21.

[0059] In some embodiments, as shown in Figure 1 and Figure 2 The stripping shovel 100 can also include a control assembly 60. The control assembly 60 can include a control switch 61 and a temperature control switch 62. The control switch 61 can be provided on the housing 10 and can control the start and stop actions of the driving assembly 30. The temperature control switch 62 can be provided between the housing 10 and the holding part 50 and can control the temperature of the hot air generated by the hot air generating assembly 42.

[0060] In some embodiments, the control assembly 60 can generally include an integrated circuit board on which a microcontroller, a power management module, a driving control module and a temperature control module can be integrated. As shown in Figure 1 and Figure 2 The control assembly 60 can obtain electric energy through an external power supply 70 provided at the tail end of the holding part 50. Accordingly, the control assembly 60 can be electrically connected to the hot air generating assembly 42 and the driving assembly 30, so as to control the start and stop actions of the driving assembly 30 through the control switch 61, and control the temperature of the hot air generated by the hot air generating assembly 42 through the temperature control switch 62.

[0061] In some embodiments, the temperature of the hot air can be precisely controlled in real time by the control assembly 60. Specifically, the temperature of the air outlet 4111 can be monitored in real time by a temperature sensor installed near the air outlet 4111, and compared with a preset temperature value. The power supplied to the heating element 422 can be adjusted by pulse width modulation or the like to achieve closed-loop temperature control, ensuring that the temperature is maintained at 120°C ± 10°C. This can enable the aged adhesive to be sufficiently softened, but not carbonized or excessively runny, thereby creating favorable conditions for subsequent mechanical spalling.

[0062] As shown in Figure 3 The present application also discloses a peeling method using the peeling spade 100 as disclosed in the above embodiments, and thus has all the technical effects of the peeling spade 100 as described above. The peeling method can include the steps of aligning the peeling spade (S100), softening the adhesive (S200), and peeling the target object (S300). The peeling method will be explained and described in detail below.
