Description

Technical Field

[0001] This application relates to the field of semiconductor technology, and more specifically, to a stripping spatula. Background Technology

[0002] In the processing of semiconductor materials such as silicon carbide, polishing is typically used to obtain a highly flat wafer surface. During polishing, a polishing cloth with strong adhesive backing is attached to a metal cloth base of the polishing machine; this metal cloth base is also known as a processing pad. When the polishing cloth reaches the end of its lifespan, it and the adhesive backing must be completely removed from the metal cloth base.

[0003] Traditionally, the cleaning of waste polishing cloths and their adhesive backing is mainly done manually using blades and dragging. This method is extremely inefficient and labor-intensive. Furthermore, the hardened adhesive backing is difficult to remove completely, and improper force can easily damage the processing pad, resulting in impaired pad surface flatness. The residual adhesive layer will affect the flatness of the new polishing cloth's adhesion and polishing effect, and may even scratch the wafer, affecting product quality.

[0004] In addition, using solvents to dissolve the glue may produce harmful gases, which will cause certain harm to the environment and operators, and solvent residue may also affect the subsequent polishing effect.

[0005] Therefore, how to improve the cleaning efficiency of polishing cloth and its aged adhesive has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this application is to provide a peeling spatula to improve the cleaning efficiency of polishing cloth and its aged adhesive backing.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] A peeling scraper, comprising:

[0009] case;

[0010] A shovel head assembly for peeling a target object from a base surface, and the shovel head assembly is movably disposed at one end of the housing;

[0011] A drive assembly is disposed within the housing and is connected to the shovel head assembly for driving the shovel head assembly to perform reciprocating motion;

[0012] A blower assembly, comprising an air guide assembly and a hot air generating assembly, wherein the hot air generating assembly is disposed within the housing, and the air guide assembly is used to guide the hot air generated by the hot air generating assembly to the bonding point between the target object and the base surface.

[0013] Optionally, in the above-mentioned stripping blade, the air guide assembly includes an air outlet connector and an air guide duct. The air outlet connector and the blade assembly are located at the same end of the housing. The air outlet connector has an air outlet. The blade assembly extends out of the air outlet. One end of the air guide duct is connected to the air outlet connector, and the hot air generating assembly is located at the other end of the air guide duct.

[0014] Optionally, in the above-mentioned stripping blade, the air outlet connector has a large-diameter end and a small-diameter end that are arranged opposite to each other. The cross-sectional area of ​​the air outlet connector gradually decreases from the large-diameter end of the air outlet connector toward the small-diameter end of the air outlet connector. The large-diameter end of the air outlet connector is connected to the housing, and at least a portion of the small-diameter end of the air outlet connector is the air outlet.

[0015] Optionally, in the above-mentioned stripping blade, the air outlet has a flat opening structure, and the air outlet is eccentrically positioned relative to the housing.

[0016] Optionally, the peeling shovel described above also includes a gripping part, which is connected to the end of the housing away from the shovel head assembly via a connecting part. The connecting part has a large-diameter end and a small-diameter end that are disposed opposite to each other. The cross-sectional area of ​​the connecting part gradually decreases from the large-diameter end of the connecting part toward the small-diameter end of the connecting part. The large-diameter end of the connecting part is connected to the housing, and the small-diameter end of the connecting part is connected to the gripping part.

[0017] Optionally, in the above-mentioned peeling blade, the gripping part is eccentrically disposed relative to the housing, and the eccentric direction of the gripping part is opposite to the eccentric direction of the air outlet.

[0018] Optionally, in the above-described stripping blade, the hot air generating assembly includes a fan for generating airflow and a heating element for heating the airflow.

[0019] Optionally, in the above-mentioned stripping shovel, the driving assembly includes a drive motor, a transmission mechanism, and a translation guide rail. The shovel head assembly is slidably disposed on the translation guide rail. The drive motor is connected to the shovel head assembly through the transmission mechanism, which is used to convert the rotational motion of the drive motor into the reciprocating motion of the shovel head assembly.

[0020] Optionally, in the above-mentioned stripping blade, the blade assembly includes a blade head and a connecting seat, the blade head is connected to the drive assembly via the connecting seat, and the blade head and the connecting seat are detachably connected.

[0021] Optionally, the above-mentioned stripping blade also includes a control component, which includes a control switch disposed on the housing for controlling the start and stop of the drive component and / or a temperature control switch for controlling the temperature of the hot air generating component.

[0022] The peeling scraper provided in this application guides hot air generated by the hot air generating component to the adhesion point between the target object and the substrate through the air guide component of the blowing assembly. This softens the adhesive at the adhesion point. The scraper head assembly is driven to reciprocate through the drive assembly, pushing it to peel the target object and the softened adhesive from the substrate. As shown in the above example, the peeling scraper provided in this application effectively reduces the adhesion of aged adhesive by heating and softening it through the hot air generating component. Simultaneously, the reciprocating motion of the scraper head assembly, driven by the drive assembly, replaces traditional manual scraping. The combined effect of these two methods significantly improves cleaning efficiency and reduces the operator's labor intensity. By softening the adhesive layer and combining it with reciprocating mechanical scraping, the polishing cloth and the backing adhesive layer can be completely and thoroughly peeled from the fabric base, avoiding adhesive residue and effectively preventing damage to the flatness of the substrate. This achieves the goal of thorough cleaning and protection of the substrate. In addition, the absence of chemical solvents avoids the generation of harmful gases, making it more environmentally friendly and operator-friendly, improving the environmental friendliness and safety of the operation. It also enables thorough and non-destructive cleaning, ensuring the flatness and firmness of the new polishing cloth adhesion, thereby ensuring the stability and uniformity of subsequent polishing processes and helping to improve the yield of the final product.

Detailed Implementation

[0029] The core of this application is to provide a peeling spatula to improve the cleaning efficiency of polishing cloth and its aged adhesive backing.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Traditionally, the cleaning of waste polishing cloths and their adhesive backing is primarily done manually, using tools such as utility knives and scrapers for scraping and tearing. This method has several drawbacks: First, it is inefficient and labor-intensive, consuming a significant amount of manpower and time. Second, during the polishing process, the adhesive backing ages and hardens due to high temperature, high pressure, and chemical reactions, becoming extremely strong and difficult to remove completely by manual scraping. Residual adhesive layers severely affect the flatness of the new polishing cloth, leading to uneven polishing results and even scratching the wafers, reducing product yield. Third, operators can easily damage the expensive cloth backing surface due to improper force when scraping, compromising its flatness. Furthermore, some auxiliary cleaning methods use chemical solvents, but these solvents are not only ineffective against some severely aged adhesives but also produce volatile organic compounds, polluting the environment and harming the health of operators.

[0032] Therefore, such as Figure 1As shown in the illustration, this application discloses a peeling scraper 100, including a housing 10, a scraper head assembly 20, a drive assembly 30, and a blower assembly 40. The aged adhesive is heated and softened by the hot air generating assembly 42, effectively reducing its adhesion. Simultaneously, the drive assembly 30 drives the scraper head assembly 20 in reciprocating motion, replacing traditional manual scraping. The synergistic effect of these two components significantly improves cleaning efficiency and reduces the operator's workload. By softening the adhesive layer and combining it with reciprocating mechanical scraping, the polishing cloth and backing adhesive layer can be completely and thoroughly peeled from the fabric base, avoiding adhesive residue and effectively preventing damage to the flatness of the substrate. This achieves thorough cleaning while protecting the substrate. Furthermore, the absence of chemical solvents avoids the generation of harmful gases, making it more environmentally friendly and operator-friendly, improving the environmental friendliness and safety of the operation. It also achieves thorough and non-destructive cleaning, ensuring the flatness and firmness of the new polishing cloth adhesion, thereby ensuring the stability and uniformity of subsequent polishing processes and contributing to improved yield of the final product.

[0033] The following will combine Figure 1 and Figure 2 The peeling blade 100 disclosed in the embodiments of this application will be explained and described in detail.

[0034] like Figure 1 and Figure 2 As shown, the housing 10 may have a cylindrical structure, and the shovel head assembly 20 is movably disposed at one end of the housing 10. The drive assembly 30 may be disposed inside the housing 10 and connected to the shovel head assembly 20 for transmission, so that the drive assembly 30 can drive the shovel head assembly 20 to reciprocate and push the shovel head assembly 20, thereby peeling the target object from the base surface through the shovel head assembly 20. The blowing assembly 40 may include an air guide assembly 41 and a hot air generating assembly 42, and the hot air generating assembly 42 may be disposed inside the housing 10 to generate hot air that can soften the colloid. The air guide assembly 41 can guide the hot air generated by the hot air generating assembly 42 to the adhesion point between the target object and the base surface, thereby softening the colloid so that the softened colloid and the target object can be peeled from the base surface by the shovel head assembly 20. It should be noted that in the above embodiments, the target material can be a polishing cloth, and the base surface can be a cloth base on the polishing equipment. The peeling spatula 100 can completely and thoroughly peel the polishing cloth and adhesive backing layer from the cloth base, avoiding adhesive residue and effectively preventing damage to the flatness of the base surface, thus achieving thorough cleaning and protecting the substrate. Of course, the target material can also be other adhesives, such as wallpaper, and the base surface can also be other adhesive surfaces, such as a wall, thereby achieving the effect of detaching the target material from the base surface using the peeling spatula 100. Unless otherwise specified below, the target material refers to the polishing cloth, and the base surface refers to the cloth base on the polishing equipment.

[0035] When using the peeling spatula 100 to peel off the target object, the hot air generated by the hot air generating component 42 can first be guided to the adhesion between the target object and the substrate by the air guide component 41 of the air blowing component 40, thereby softening the adhesive at the adhesion. Then, the drive component 30 drives the spatula head assembly 20 to reciprocate and push the spatula head assembly 20 to peel the target object and the softened adhesive from the substrate.

[0036] The peeling blade 100 disclosed in this application embodiment can guide the hot air generated by the hot air generating component 42 to the adhesion between the target object and the substrate through the air guide component 41 of the blowing component 40, thereby softening the adhesive at the adhesion to effectively reduce its adhesion force. Furthermore, the drive component 30 can drive the scraper head component 20 to reciprocate and push the scraper head component 20 to peel the target object and the softened adhesive from the substrate.

[0037] The peeling scraper 100 disclosed in this application uses a hot air generating component 42 to heat and soften the aged adhesive, effectively reducing its adhesion. Simultaneously, a drive component 30 drives the scraper head component 20 in reciprocating motion, replacing traditional manual scraping. The combined effect of these two mechanisms significantly improves cleaning efficiency and reduces the operator's workload. By softening the adhesive layer and combining it with reciprocating mechanical scraping, the polishing cloth and backing adhesive layer can be completely and thoroughly peeled from the fabric base, avoiding adhesive residue and effectively preventing damage to the flatness of the substrate. This achieves thorough cleaning while protecting the substrate. Furthermore, the absence of chemical solvents avoids the generation of harmful gases, making it more environmentally friendly and operator-friendly, improving the environmental friendliness and safety of the operation. It also achieves thorough and non-destructive cleaning, ensuring the flatness and firmness of the new polishing cloth adhesion, thereby ensuring the stability and uniformity of subsequent polishing processes and contributing to a higher yield rate of the final product.

[0038] In some embodiments, such as Figure 1 and Figure 2 As shown, the air guiding assembly 41 may include an air outlet connector 411 and an air guiding duct 412. The air outlet connector 411 and the shovel head assembly 20 are located at the same end of the housing 10, and the air outlet connector 411 has an air outlet 4111. The shovel head assembly 20 can extend out of the air outlet 4111. At the same time, one end of the air guiding duct 412 is connected to the air outlet connector 411, and the hot air generating assembly 42 can be located at the other end of the air guiding duct 412, so that the hot air generated by the hot air generating assembly 42 can be guided by the air guiding duct 412 to the air outlet 4111 of the air outlet connector 411 and blown towards the bonding area between the target object and the substrate, thereby heating and softening the colloid.

[0039] In some embodiments, such as Figure 1 and Figure 2As shown, the air outlet connector 411 may have a large-diameter end and a small-diameter end arranged opposite to each other. The cross-sectional area of ​​the air outlet connector 411 gradually decreases from the large-diameter end towards the small-diameter end. The large-diameter end of the air outlet connector 411 is connected to the housing 10, and the air outlet 4111 may have a flat opening structure to provide space for the reciprocating motion of the shovel head assembly 20. Furthermore, one, two, or more air guide ducts 412 may be used to increase the hot air output and ensure the softening efficiency of the colloid. At least a portion of the small-diameter end of the air outlet connector 411 can be an air outlet 4111, that is, the small-diameter end of the air outlet connector 411 can be partially set as an air outlet 4111, while the remaining part is a closed area, so that hot air can be concentrated and sent out from the air outlet 4111, thereby improving the softening efficiency of the colloid. Of course, the small-diameter end of the air outlet connector 411 can also be entirely set as an air outlet 4111, so as to increase the area of ​​the hot air outlet 4111, ensure the uniformity of hot air blowing out, and thus achieve uniform softening of the colloid.

[0040] In some embodiments, the air outlet 4111 may be centrally arranged relative to the housing 10. Of course, as... Figure 1 and Figure 2 As shown, the air outlet 4111 can also be eccentrically positioned relative to the housing 10 in the direction towards the base surface. Simultaneously, the scraper head assembly 20 can extend from the air outlet 4111, meaning the scraper head assembly 20 can be eccentrically positioned relative to the housing 10 in the direction towards the base surface. For ease of understanding, the surface connecting the upper edge of the air outlet connector 411 and the air outlet 4111 is defined as the upper air outlet surface, and the surface connecting the lower edge of the air outlet connector 4111 and the air outlet 4111 is defined as the lower air outlet surface. Furthermore, the angle between the upper air outlet surface and the base surface is greater than the angle between the lower air outlet surface and the base surface. This allows for a wider range of adjustment of the working angle of the peeling scraper 100, meeting the needs of different scenarios. It also ensures that the hot air is more evenly distributed when it reaches the adhesion point between the target object and the base surface, guaranteeing the uniformity of colloid softening.

[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, the peeling spatula 100 may also include a gripping portion 50 for facilitating the pushing of the spatula head assembly 20. The gripping portion 50 can be connected to the end of the housing 10 away from the spatula head assembly 20 via a connecting portion 51, thereby facilitating the operator to grasp the gripping portion 50 to push the spatula head assembly 20 to peel the target object and softened colloid from the base surface. Simultaneously, heat insulation layers are provided on the gripping portion 50 and the housing 10 to ensure operational safety.

[0042] In some embodiments, such as Figure 1As shown, the connecting portion 51 may have a large-diameter end and a small-diameter end that are disposed opposite to each other, 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 may be connected to the housing 10, and the small-diameter end of the connecting portion 51 may be connected to the gripping portion 50.

[0043] In some embodiments, the grip 50 may be centrally arranged relative to the housing 10. Of course, as... Figure 1 As shown, the grip 50 can also be eccentrically positioned relative to the housing 10 in a direction away from the base surface. That is, the eccentric direction of the grip 50 is opposite to the eccentric direction of the air outlet 4111, thereby ensuring that the operator has a large gripping space to adapt to the adjustment of the working angle of the peeling blade 100 and meet the usage needs of different scenarios.

[0044] In some embodiments, such as Figure 2 As shown, the hot air generating assembly 42 may include a fan 421 and a heating element 422. The fan 421 can be adapted to the air duct 412, meaning that a fan 421 can be installed at one end of each air duct 412 to generate airflow through the air duct 412. Simultaneously, a heating chamber can be independently provided within the housing 10, and the heating element 422 can be located within the heating chamber. The air duct 412 can be connected to the heating chamber via the fan 421, allowing the fan 421 to guide the hot airflow from the heating chamber into the air duct 412 and blow it from the air outlet 4111 towards the bonding area between the target object and the substrate, thereby softening the colloid.

[0045] In the above embodiments, the heating element 422 may be a plurality of electric heating tubes, and each electric heating tube may be fixed in the heating chamber by a base. Meanwhile, the fan 421 may be a centrifugal fan, so that the airflow generated by the centrifugal fan may be heated by each electric heating tube.

[0046] In some embodiments, the fan 421 is a centrifugal fan, and the fan 421 can be located near the air inlet inside the housing 10. When the fan 421 rotates, it can draw in ambient air from outside the peeling blade 100 and pressurize it to form a stable airflow. At the same time, the heating element 422 can be located in the air outlet path of the fan 421 to heat the air flowing through it. The heating element 422 can be a thermistor ceramic heater, which has the characteristics of rapid heating, self-controlled constant temperature, high heat conversion efficiency and good safety. Alternatively, the heating element 422 can also be a traditional resistance wire heater, and a temperature sensor can be used for precise temperature control.

[0047] In some embodiments, such as Figure 2As shown, the drive assembly 30 may include a drive motor 31, a transmission mechanism 32, and a translation guide rail 33. The shovel head assembly 20 is slidably mounted on the translation guide rail 33, and the drive motor 31 is connected to the shovel head assembly 20 via the transmission mechanism 32. The transmission mechanism 32 converts the rotational motion of the drive motor 31 into the reciprocating motion of the shovel head assembly 20, thereby enabling rapid peeling of the target object through the reciprocating motion of the shovel head assembly 20.

[0048] In some embodiments, the drive motor 31 may be a high-torque brushless DC motor, and an eccentric wheel may be fixed on the output shaft of the drive motor 31. Meanwhile, the transmission mechanism 32 may include a connecting rod that cooperates with the eccentric wheel, with one end of the connecting rod connected to the eccentric wheel of the drive motor 31 and the other end connected to the shovel assembly 20. When the drive motor 31 rotates, the eccentric wheel drives the connecting rod, precisely converting the rotational motion into linear reciprocating motion of the shovel assembly 20 on the translation guide rail 33. The frequency of the reciprocating motion of the shovel assembly 20 can be adjusted according to the rotational speed of the drive motor 31, thereby significantly reducing the manual pushing force required for a single shovel stroke through the high-frequency reciprocating shoveling action of the shovel assembly 20, effectively overcoming the strong adhesive force of aged adhesive. It should be noted that the drive motor 31 can also achieve the reciprocating motion of the shovel head assembly 20 on the translation guide rail 33 through a crank-connecting rod mechanism. That is, a crank can be fixed on the output shaft of the drive motor 31, and the transmission mechanism 32 can include a connecting rod that cooperates with the crank. One end of the connecting rod is connected to the crank of the drive motor 31, and the other end of the connecting rod is connected to the shovel head assembly 20. When the drive motor 31 rotates, the crank can drive the connecting rod to accurately convert the rotational motion into linear reciprocating motion of the shovel head assembly 20 on the translation guide rail 33.

[0049] In some embodiments, the drive assembly 30 may be directly constituted by a linear electromagnetic actuator, instead of a combination of a drive motor 31 and a transmission mechanism 32. The linear electromagnetic actuator is an actuator that directly converts electrical energy into linear motion, and its internal components may include an electromagnetic coil and a movable iron core actuator. The fixed housing of the linear electromagnetic actuator is securely mounted inside the housing 10 of the peeling blade 100, and the output end of the retractable iron core actuator can be directly or rigidly connected to the shovel head assembly 20 via a connector. The shovel head assembly 20 may also be slidably mounted on the translation guide rail 33 to ensure the stability of the reciprocating motion of the shovel head assembly 20.

[0050] In some embodiments, such as Figure 1 and Figure 2As shown, the shovel head assembly 20 may include a shovel head 21 and a connecting seat 22. The shovel head 21 may be made of a material with high temperature resistance, wear resistance, and a low coefficient of friction, such as Teflon-coated metal, ceramic, or specific engineering plastics. The end of the shovel head 21 may be equipped with a cutting edge to achieve rapid peeling of the target object and the substrate. The shovel head 21 can be connected to the drive assembly 30 via the connecting seat 22, allowing the drive assembly 30 to drive the shovel head 21 to reciprocate, thereby achieving rapid peeling of the target object. Simultaneously, the shovel head 21 and the connecting seat 22 can be fixed by a detachable connection such as plug-in, snap-fit, or bolt connection to facilitate replacement of the shovel head 21.

[0051] In some embodiments, such as Figure 1 and Figure 2 As shown, the shovel head 21 is connected to the connecting seat 22, and the shovel head 21 and the connecting seat 22 can be locked and fixed by a shovel head lock 23 that can be quickly released. The shovel head lock 23 can be a knob lock, so that the shovel head 21 and the connecting seat 22 can be quickly locked or released by rotating the knob lock.

[0052] In some embodiments, the connecting seat 22 may be provided with a groove, and the shovel head 21 may be provided with a protrusion that can slide into the groove. One or more first mounting holes may be provided through the connecting seat 22, located on the groove wall. The protrusion of the shovel head 21 may be provided through a second mounting hole adapted to the first mounting hole, allowing fasteners such as bolts to pass through the first and second mounting holes and be locked in place with a lock nut. The groove may be a T-shaped groove, C-shaped groove, or dovetail groove, and the protrusion may have a T-shaped, C-shaped, or dovetail cross-section adapted to the groove, allowing the protrusion of the shovel head 21 to slide into the groove of the connecting seat 22, thereby restricting the rotation of the shovel head 21. Alternatively, a protrusion may be provided on the connecting seat 22, and a groove may be provided on the shovel head 21, allowing the protrusion on the connecting seat 22 to slide into the groove of the shovel head 21; this is not limited herein.

[0053] In some embodiments, a stop may be provided in the slide groove to limit the sliding of the protrusion and prevent the protrusion from sliding out of the slide groove. At the same time, it can ensure that the first mounting hole and the second mounting hole are quickly aligned, so as to realize the quick installation between the connecting seat 22 and the shovel head 21.

[0054] In some embodiments, such as Figure 1 and Figure 2As shown, the peeling blade 100 may also include a control component 60. The control component 60 may include a control switch 61 and a temperature control switch 62. The control switch 61 may be disposed on the housing 10 and may control the start and stop of the drive component 30. The temperature control switch 62 may be disposed between the housing 10 and the gripping part 50 and may control the temperature of the hot air generated by the hot air generating component 42.

[0055] In some embodiments, the control component 60 may typically include an integrated circuit board on which a microcontroller, power management module, drive control module, and temperature control module may be integrated. Figure 1 and Figure 2 As shown, the control component 60 can obtain electrical energy from an external power supply 70 located at the tail end of the grip portion 50. Accordingly, the control component 60 can be electrically connected to the hot air generating component 42 and the drive component 30, so that the start and stop operation of the drive component 30 can be controlled by the control switch 61, and the temperature of the hot air generated by the hot air generating component 42 can be controlled by the temperature control switch 62.

[0056] In some embodiments, the control component 60 can achieve precise real-time control of the hot air temperature. Specifically, a temperature sensor installed near the air outlet 4111 can monitor the temperature of the air outlet 4111 in real time and compare it with a preset temperature value. The power supplied to the heating element 422 can be adjusted by means of pulse width modulation, etc., to achieve closed-loop temperature control and ensure that the temperature is maintained at 120°C±10°C. This allows the aged adhesive to be softened sufficiently without carbonizing or excessively flowing, creating favorable conditions for subsequent mechanical scraping. At the same time, the control component 60 can also respond to the command of the control switch 61 to control the drive control module to supply power to or de-energize the drive component 30.

[0057] like Figure 3 As shown in the figure, this application also discloses a peeling method, which uses the peeling spatula 100 disclosed in the above embodiment, and therefore has all the technical effects of the peeling spatula 100, which will not be repeated here. The peeling method may include step S100 aligning the peeling spatula, step S200 softening the colloid, and step S300 peeling the target object. The following will combine... Figures 1 to 3 The stripping method disclosed in the embodiments of this application will be explained and described in detail.

[0058] Step S100: Align with the peeling spatula;

[0059] Align the peeling blade's head assembly 20 with the opening at the edge where the target object and the substrate are bonded. Specifically, first use the blade to tear an opening along the edge where the target object and the substrate are bonded, then align the peeling blade's head assembly 20 with the opening at the edge where the target object and the substrate are bonded.

[0060] Step S200: Soften the colloid;

[0061] Hot air is delivered by the blower assembly 40 toward the adhesive joint between the target object and the substrate to soften the adhesive. Specifically, by turning on the temperature control switch 62, hot air is delivered through the air guide pipes 412 on both sides to the air outlet 4111 and blown toward the adhesive joint between the target object and the substrate to soften the adhesive.

[0062] Step S300: Peel off the target object;

[0063] The shovel assembly 20 reciprocates and pushes the peeling blade to peel the target object and softened colloid from the base surface. Specifically, by activating the control switch 61, the shovel assembly 20 reciprocates and moves forward step by step, thereby gradually peeling the target object and softened colloid from the base surface.

[0064] The terminology used in the above embodiments is for the purpose of describing specific embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions "a," "an," "the," "the," "the," and "this" are intended to also include expressions such as "one or more," unless the context clearly indicates otherwise.
