[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0004] The purpose of this disclosure is to provide a self-adhesive box assembly that at least partially protects components from damage during transportation, storage, and desorption.

[0005] This disclosure provides a self-adhesive box assembly, characterized in that the self-adhesive box assembly comprises:

[0006] The box body has a first mounting cavity inside it;

[0007] An adsorption assembly includes a self-adsorption membrane and multiple support columns. The self-adsorption membrane is disposed in a first mounting cavity and forms an air intake space within the first mounting cavity. The multiple support columns are spaced apart in the air intake space to support the self-adsorption membrane. The side of the self-adsorption membrane facing away from the support columns is used to adsorb the object to be adsorbed.

[0008] An air extraction assembly is connected to the air extraction space via a connecting pipe. When the air extraction assembly extracts air, the self-adsorption membrane is partially embedded in the gap between the support columns.

[0011] An air extraction block is located at the bottom of the main board. The air extraction block has an air passage that is connected to the air intake space and the connecting pipe, respectively.

[0012] According to one embodiment of this disclosure, the box body further includes:

[0013] An adapter block is provided on the side of the air extraction block, and a connection hole is provided on the adapter block, which communicates with the air passage.

[0014] According to one embodiment of this disclosure, the connecting pipe is connected to the vacuum block.

[0015] According to one embodiment of the present disclosure, the first mounting cavity includes a first hole segment and a second hole segment. The second hole segment is located at one end of the first hole segment near the top surface of the motherboard. The cross-sectional area of ​​the first hole segment is smaller than the cross-sectional area of ​​the second hole segment to form a stepped first mounting cavity. The self-adhesive membrane is connected to the bottom surface of the second hole segment.

[0016] According to one embodiment of this disclosure, the air extraction assembly is a self-locking air pump, and the self-locking air pump includes:

[0017] Piston cylinder;

[0018] A piston rod is disposed inside the piston cylinder, and a piston head is provided at the end of the piston rod.

[0019] According to one embodiment of this disclosure, the piston rod is provided with threads, and the self-locking piston further includes:

[0020] A threaded knob is connected to the piston rod, and when the threaded knob is rotated, it can push the piston rod to move relative to the piston cylinder.

[0021] According to one embodiment of this disclosure, the self-adsorption membrane is a flexible membrane.

[0022] According to one embodiment of this disclosure, the box body, the adsorption component, and the air extraction component are provided with an electrostatic dissipative coating; and / or the box body, the adsorption component, and the air extraction component are made of an electrostatic dissipative material.

[0023] According to one embodiment of this disclosure, the self-adhesive box assembly further includes:

[0024] A lid is provided on the box body and is used to protect the self-adsorption membrane and the object to be adsorbed.

[0025] The self-adsorption box assembly provided in this embodiment includes a box body, an adsorption component, and a vacuum component. The box body has a first mounting cavity. The adsorption component includes a self-adsorption membrane and multiple support pillars. The self-adsorption membrane is disposed in the first mounting cavity and forms a suction space within the cavity. The multiple support pillars are spaced apart in the suction space to support the self-adsorption membrane. The side of the self-adsorption membrane facing away from the support pillars is used to adsorb the object to be adsorbed. The vacuum component is connected to the suction space via a connecting pipe. When the vacuum component vacuums, the self-adsorption membrane is partially embedded in the gaps between the support pillars. By adsorbing the object to be adsorbed through the self-adsorption membrane disposed within the box body, damage to the object to be adsorbed during transportation or storage can be avoided, thus protecting the object. Furthermore, by vacuuming the gas in the suction space, the self-adsorption membrane is partially embedded in the gaps between the support pillars, reducing the suction force between the self-adsorption membrane and the object to be adsorbed. This improves the convenience of removing the object from the self-adsorption membrane, avoids damage to the object or workpiece during removal, and increases the efficiency of workpiece removal.

Therefore, it should be understood that various modifications and changes can be made to the exemplary embodiments without departing from the scope of protection of this disclosure.

[0043] Furthermore, it should be understood that the directional terms such as "upper," "lower," "inner," and "outer" described in the exemplary embodiments of this disclosure are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the exemplary embodiments of this disclosure.

[0044] This disclosure provides an exemplary embodiment of a self-adhesive box assembly, such as... Figures 1-10 As shown, the self-adsorption box assembly includes: a box body 10, an adsorption component 20, and an air extraction component 30. The box body 10 has a first mounting cavity. The adsorption component 20 includes a self-adsorption membrane 21 and multiple support columns 22. The self-adsorption membrane 21 is disposed in the first mounting cavity and forms an air extraction space in the first mounting cavity. The multiple support columns 22 are spaced apart in the air extraction space to support the self-adsorption membrane 21. The side of the self-adsorption membrane 21 facing away from the support columns 22 is used to adsorb the object to be adsorbed 01. The air extraction component 30 is connected to the air extraction space through a connecting pipe 31. When the air extraction component 30 extracts air, the self-adsorption membrane 21 is partially embedded in the gap between the support columns 22.

[0045] The self-adsorption box assembly provided in this embodiment includes a box body 10, an adsorption component 20, and an air extraction component 30. The box body 10 has a first mounting cavity. The adsorption component 20 includes a self-adsorption membrane 21 and a plurality of support columns 22. The self-adsorption membrane 21 is disposed in the first mounting cavity and forms an air extraction space in the first mounting cavity. The plurality of support columns 22 are spaced apart in the air extraction space to support the self-adsorption membrane 21. The side of the self-adsorption membrane 21 facing away from the support columns 22 is used to adsorb the object to be adsorbed 01. The air extraction component 30 is connected to the air extraction space through a connecting pipe 31. When the air extraction component 30 extracts air, the self-adsorption membrane 21 is partially embedded in the gap between the support columns 22. The self-adsorption membrane 21 located within the box body 10 adsorbs the object to be adsorbed 01, preventing damage to the object during transportation or storage and protecting it. Furthermore, the suction assembly 30 extracts gas from the suction space, causing the self-adsorption membrane 21 to partially embed within the gaps between the support columns 22. This reduces the suction force between the self-adsorption membrane 21 and the object to be adsorbed 01, improving the ease of removing the object from the self-adsorption membrane 21, preventing damage to the object or workpiece during removal, and increasing the efficiency of workpiece removal. The suction assembly 30 is connected to the suction space via a connecting pipe 31, allowing for detachment of the suction assembly 30 and the box body 10, enhancing the convenience of connection and operation.

[0046] The following will describe in detail the various parts of the self-adhesive box assembly provided in the embodiments of this disclosure:

[0047] like Figure 2 As shown, the box body 10 includes a main board 11 and an air extraction block 12. The main board 11 has a first mounting cavity with an opening on its top surface. The air extraction block 12 is located at the bottom of the main board 11 and has air passages that connect to the suction space and the connecting pipe 31. The connecting pipe 31 and the air extraction block 12 are connected; for example, the connecting pipe 31 and the air extraction block 12 can be fixedly connected or detachably linked.

[0048] Furthermore, the main body 10 may also include an adapter block 13, which is located on the side of the suction block 12. The adapter block 13 has a connection hole that communicates with the air passage. One end of the connection hole is connected to the connecting pipe 31 (fixed connection or detachable connection), and the other end of the connection hole communicates with the air passage.

[0049] The motherboard 11 can have a cuboid or near-cuboid structure, and the shape of the first mounting cavity matches the shape of the motherboard 11. The first mounting cavity can be a cuboid or near-cuboid blind hole disposed on the motherboard 11, and the first mounting cavity has an opening on the top surface of the motherboard 11. Of course, in practical applications, the motherboard 11 can also be other shapes, such as a cylinder, etc., and the embodiments disclosed herein are not limited thereto.

[0050] The first mounting cavity includes a first hole segment and a second hole segment. The second hole segment is located at one end of the first hole segment near the top surface of the motherboard 11. The cross-sectional area of ​​the first hole segment is smaller than that of the second hole segment to form a stepped first mounting cavity. The self-adhesive membrane 21 is connected to the bottom surface of the second hole segment. The first hole segment is used to accommodate the support post 22, and the second hole segment is used to accommodate the self-adhesive membrane 21.

[0051] The self-adsorption membrane 21 and the bottom wall of the second pore section are sealed together to form a closed suction space. Multiple vent holes are provided on the bottom wall of the first mounting hole, which are used to communicate with the air passages on the suction block 12. For example, when the first mounting hole has a cuboid structure, four vent holes are provided on the bottom wall of the first mounting hole, with each of the four vent holes located at one of the four vertices of the rectangle.

[0052] Multiple support columns 22 are discretely arranged in the suction space. When the suction assembly 30 suctions air, the pressure in the suction space is less than atmospheric pressure. At this time, under the action of atmospheric pressure, the part of the self-adsorption membrane 21 outside the support column 22 is concave downward, thereby reducing the contact area between the self-adsorption membrane 21 and the workpiece 01 to be adsorbed, and reducing the suction force of the self-adsorption membrane 21 on the workpiece 01 to be adsorbed. This makes it easier to remove the workpiece 01 from the self-adsorption box assembly and avoids damage to the workpiece when removing the workpiece 01.

[0053] Multiple support pillars 22 can be directly installed at the bottom of the first mounting cavity. For example, multiple support pillars 22 can be connected to the bottom of the first mounting cavity by adhesive bonding, or multiple support pillars 22 can be integrally molded with the motherboard 11 by injection molding or other methods. The surface of the support pillars 22 has a flexible layer, or the support pillars 22 are made of flexible materials to avoid the support pillars 22 damaging the adsorbed component 01.

[0054] It is understood that multiple support columns 22 can be installed on the base, which is located at the bottom of the first mounting cavity. The multiple support columns 22 are arranged in a topological structure composed of basic geometric shapes such as rectangles, circles, and triangles to facilitate support for various shapes and sizes of objects to be adsorbed, such as the components 01, during low-pressure release. Figure 3 As shown, taking a triangular arrangement as an example, the centers of the three support pillars 22 form an equilateral triangle. When the rectangular adsorbent 01 above it needs low-pressure desorption, the gaps between corners C and D of the adsorbent 01 and the deformed membrane are small, preventing the adsorbent 01 from moving easily. Larger gaps appear at corners A and B, allowing the adsorbent 01 to be removed using tweezers, an adsorption pen, or other tools. Figure 4 As shown, when triangles form a topological structure, each support pillar 22 can form a triangle with two adjacent support pillars 22. Multiple adjacent triangles form a larger array, thus this array of support pillars 22 can support and adsorb a large number of objects 01 of different shapes and sizes. Similarly, as... Figure 5 As shown, the circular topology can also support and adsorb a large number of objects of different shapes and sizes.

[0055] The suction block 12 is located at the bottom of the main board 11. The air passage on the suction block 12 has an opening on the top surface of the suction block 12, and the orthographic projection of the vent on the suction block 12 at least partially coincides with the opening of the air passage. An air inlet is provided on the side of the suction block 12 facing the adapter block 13, and the air inlet is connected to the connection hole on the adapter block 13.

[0056] In this embodiment, the vacuum block 12 and the main board 11 can be separate molding structures, and the vacuum block 12 and the main board 11 are sealed together. For example, a sealing ring can be provided between the vacuum block 12 and the main board 11, or a sealant layer can be applied between the vacuum block 12 and the main board 11, or the vacuum block 12 and the main board 11 can be bonded or welded, etc. Of course, in practical applications, the vacuum block 12 and the main board 11 can also be integral molding structures, and this embodiment is not limited thereto.

[0057] The adapter block 13 is used to connect the vacuum block 12 and the vacuum assembly 30. The adapter block 13 is sealed to the side of the vacuum block 12. In order to improve the uniformity of the appearance of the self-adhesive box assembly, the height of the adapter block 13 can be the same as the sum of the heights of the vacuum block 12 and the main board 11.

[0058] The connecting hole inside the adapter block 13 includes a first connecting section and a second connecting section. The first connecting section is perpendicular to the top surface of the adapter block 13 and extends through the top surface of the adapter block 13. The first connecting section is used to connect the connecting pipe 31. The bottom end of the second connecting section is connected to the first connecting section. The second connecting section is parallel to the top surface of the adapter block 13 and is connected to the air inlet.

[0059] The adapter block 13 and the suction block 12 can be connected by means of adhesive bonding, welding (such as ultrasonic welding), bolting, or riveting. The side of the adapter block 13 facing the suction block 12 is flat, and the adapter block 13 and the suction block 12 are sealed together. For example, a sealing ring is provided between the adapter block 13 and the suction block 12, or a sealing adhesive layer can be provided between the adapter block 13 and the suction block 12.

[0060] The connecting pipe 31 and the adapter block 13 can be detachably or fixedly connected. For example, the end of the connecting pipe 31 is provided with a threaded part, and the adapter block 13 is provided with a threaded hole, so that the connecting pipe 31 and the adapter block 13 can be detachably connected by threads. Alternatively, a snap-fit ​​structure can be provided on the adapter block 13, so that the connecting pipe 31 snaps into the adapter block 13.

[0061] The air extraction assembly 30 is a self-locking air pump, such as Figure 6 As shown, the self-locking air pump includes a piston cylinder 32 and a piston rod 33. The piston rod 33 is disposed inside the piston cylinder 32, and a piston head 331 is provided at the end of the piston rod 33. The piston cylinder 32 is connected to the housing body 10 through a connecting pipe 31. For example, the piston cylinder 32 and the connecting pipe 31 can be fixedly connected or detachably connected.

[0062] It should be noted that in this embodiment, at least one end of the connecting pipe 31 is detachable. For example, the connecting pipe 31 is detachably connected to the box body 10, or the connecting pipe 31 is detachably connected to the piston cylinder 32, or the connecting pipe 31 is detachably connected to both the box body 10 and the piston cylinder 32.

[0063] The piston rod 33 is threaded, and the self-locking piston also includes a threaded knob 34. The threaded knob 34 is mounted on the piston rod 33, and when the threaded knob 34 rotates, it can push the piston rod 33 to move relative to the piston cylinder 32. When the threaded knob 34 rotates, the threaded piston rod 33 also rotates, and at the same time, the piston rod 33 moves axially; when the threaded knob 34 stops, the piston rod 33 stays in this position and does not move due to pressure difference, thus achieving self-locking.

[0064] During low-pressure desorption, the low-pressure environment within the self-adsorption box assembly needs to be maintained for a certain period of time to facilitate operations such as taking out and placing the adsorbed object 01. Therefore, the air pump needs to have a locking function. A lead screw consisting of a threaded rod and a threaded knob 34 achieves the locking function. When the knob is turned, the piston disc (piston head 331) fixed on the threaded rod moves linearly inside the cylinder, thereby drawing the gas from the self-adsorption box assembly into the piston cylinder 32; after the knob stops rotating, the position of the piston disc is fixed, achieving locking.

[0065] For example, such as Figure 7 As shown, the threaded rod and piston disc in the cylindrical piston structure are fixedly connected as a single unit, with no relative displacement between them. A rubber stopper 332 (rubber ring) is connected to the outer edge of the piston disc. The edge of the rubber ring adopts a double-triangular or multi-triangular cross-section structure to ensure good airtightness. The disc-type knob has a threaded hole in the center, with a diameter identical to the outer diameter of the threaded rod. The diameter-to-height ratio (diameter to height ratio) of the cylindrical wall can be selected from 0.5 to 10, resulting in a shorter disc stroke and a larger suction volume.

[0066] The piston cylinder 32 may include a first end plate, a second end plate, and a cylinder body. The cylinder body has openings at both ends, and the first and second end plates respectively seal both ends of the cylinder body. A through hole is provided on the first end plate, and a connecting pipe 31 is connected to the through hole on the first end plate. A through hole is provided on the second end plate, and the piston rod 33 passes through the through hole on the second end plate. In use, a threaded knob 34 abuts against the second end plate. When the threaded knob 34 rotates, the second end plate limits the movement of the threaded knob 34, thereby causing the piston rod 33 to move axially relative to the piston cylinder 32.

[0067] The vacuum assembly 30 is provided with multiple connecting pipes, each connecting pipe being connected to one box body 10. By using one vacuum assembly 30 to vacuum multiple box bodies 10, the number of vacuum assemblies can be reduced, thereby saving costs. Of course, in practical applications, the vacuum assembly 30 may also be provided with only one connecting pipe, and this embodiment is not limited thereto.

[0068] In one feasible embodiment of this disclosure, an electrostatic dissipative coating is provided on the box body 10, the adsorption component 20, and the air extraction component 30. The sheet resistance of the material used in the electrostatic dissipative coating is 10⁻⁶. 4 ~10 10 By providing an electrostatic dissipation coating on the box body 10, the adsorption component 20, and the air extraction component 30, the self-adsorption box assembly has an electrostatic dissipation function, thereby preventing electrostatic damage to the adsorbed part 01 in the self-adsorption box assembly.

[0069] In another feasible embodiment, the box body 10, the adsorption component 20, and the air extraction component 30 are made of an electrostatic dissipative material. The sheet resistance of the electrostatic dissipative material is 10 Ω. 4 ~10 10 By using electrostatic dissipative materials to make the box body 10, adsorption component 20 and air extraction component 30, the self-adsorption box assembly has electrostatic dissipation function, thereby preventing electrostatic damage to the adsorbed part 01 from the self-adsorption box assembly.

[0070] It is understandable that some components of the box body 10, the adsorption component 20, and the air extraction component 30 are made of electrostatic dissipative materials, while other components of the box body 10, the adsorption component 20, and the air extraction component 30 are covered with an electrostatic dissipative coating.

[0071] The self-adsorption membrane 21 is a flexible membrane that can deform when the pressure on both sides is different. The self-adsorption membrane 21 can automatically adsorb the component 01 to be adsorbed through low-pressure adsorption or bonding. The component 01 to be adsorbed can be a sheet-like workpiece such as a surface mount component, chip, or ceramic sheet.

[0072] like Figure 9 As shown, when the self-adsorption membrane 21 adsorbs the object to be adsorbed 01, the air pressure on both sides of the self-adsorption membrane 21 is the same, and the self-adsorption membrane 21 has a planar or nearly planar structure, resulting in a large contact area between the self-adsorption membrane 21 and the object to be adsorbed 01. When it is necessary to remove the object to be adsorbed 01, the suction space is evacuated by the suction assembly 30, causing the self-adsorption membrane 21 to deform, as shown... Figure 10 As shown, the contact area between the self-adsorption membrane 21 and the adsorbent 01 is reduced, thereby reducing the adsorption force between the self-adsorption membrane 21 and the adsorbent 01, making it easier to remove the adsorbent 01.

[0073] The lid is fitted onto the box body 10 and is used to protect the self-adhesive film 21 and the item to be adsorbed 01. The lid and the box body 10 can be connected by snap-fit ​​or by hinges.

[0074] In this embodiment, the self-adsorption box assembly is used as follows: First, open the box cover and place the object to be adsorbed 01 onto the self-adsorption membrane 21 in sequence. After storage, when taking it out, first insert the connector of the connecting tube 31 into the vent hole of the box body 10. The connector and the hole are interference-fitted to achieve good airtightness. Then, turn the threaded knob 34, and the air pump draws the air pressure in the area below the self-adsorption membrane 21 to a low-pressure state. After stopping the rotation, the air pump automatically locks, and the internal air pressure remains unchanged. Then, take out the object to be adsorbed 01. Finally, pull out the connecting tube 31, and the internal air pressure returns to atmospheric pressure.

[0075] In one feasible embodiment, the method for preparing the self-adsorption box assembly may include the following steps:

[0076] Preparation of main board 11 and air extraction block 12: ABS (acrylonitrile, butadiene, styrene terpolymer) insulating material is used to prepare main board 11 and air extraction block 12 by secondary injection molding. The air vent is set in the lower right corner of main board 11, and then the two are connected as one piece.

[0077] Preparation of the self-adsorption membrane 21 and the support column array 22: The self-adsorption membrane 21 is prepared by casting using high-viscosity insulating PDMS (polydimethylsiloxane) material, and the membrane surface is viscous; at the same time, the support column array 22 (triangular topological array) is prepared in a concave mold using food-grade silicone by casting, and the upper surface of the column is viscous after peeling; then the surface of the self-adsorption membrane 21 and the upper surface of the support column array 22 are brought into contact to connect the two into one, at which point the membrane is in a flat state.

[0078] Step S13, assembling the self-adsorption membrane 21: Connect the self-adsorption membrane 21 and the support column 22 array to the groove of the main board 11. The bottom surface of the membrane edge and the bottom surface of the column base are adhesive, which can be seamlessly attached and adhered to the inside of the smooth and flat groove, thereby forming a flexible adsorption stage.

[0079] Preparation of piston cylinder 32 wall and connecting pipe 31 (venting hose): The piston cylinder 32 wall is prepared by injection molding using PMMA (polymethyl methacrylate) material with a diameter-to-height ratio of 2. Then, the pipe end of the PE hose is connected to the air inlet and outlet of the cylinder wall and the connection is sealed.

[0080] Piston structure and knob fabrication: Using ABS material, the knob and threaded rod with disc are manufactured by injection molding and assembled. Then, using silicone material, a double-sided rubber ring is fabricated on the disc by casting. The piston structure is then assembled inside the cylinder wall, and the rubber ring and the cylinder wall can be lubricated with a small amount of silicone oil.

[0081] Preparation of the lid: A transparent flip lid is made of PMMA material by injection molding and then assembled onto the adsorption box.

[0082] In another feasible embodiment, the method for preparing the self-adsorption box assembly may include the following steps:

[0083] Fabrication of mainboard 11, vacuum block 12, and adapter block 13: Modified PMMA material (sheet resistance 10) was used. 9 ~10 10 The main board 11, the vacuum block 12, and the adapter block 13 are manufactured by a two-stage injection molding process and then connected together.

[0084] Preparation of the self-adsorption membrane 21 and support pillar 22 array: using modified PDMS material (sheet resistance of 10).9 ~10 10 A self-adsorption membrane 21 is prepared by casting, and the membrane surface is adhesive. At the same time, a support column array 22 (circular topological array) is prepared in a concave mold using food-grade silicone by casting. After peeling, the upper surface of the support column 22 is adhesive. Then, the surface of the self-adsorption membrane 21 and the upper surface of the support column array 22 are brought into contact to connect the two into one, and the membrane is in a flat state at this time.

[0085] Assemble the self-adsorption membrane 21: Connect the self-adsorption membrane 21 and the column array to the groove of the main board 11. The bottom surface of the membrane edge and the bottom surface of the column base are adhesive, which can be seamlessly attached and adhered to the inside of the smooth and flat groove, thereby forming a flexible adsorption stage.

[0086] Preparation of the wall of the electrostatic dissipative piston cylinder 32 and the connecting pipe 31: Modified PMMA material (sheet resistance of 10) was used. 9 ~10 10 The piston cylinder wall was prepared by casting with a diameter-to-height ratio of 1. At the same time, the inner and outer surfaces of the PE hose were treated with an electrostatic dissipative coating. Then the hose was connected to the air inlet and outlet of the cylinder wall and the connection was sealed.

[0087] Preparation of piston structure and threaded knob 34: Using PMMA material, the knob and threaded rod with disc are prepared by injection molding and assembled together. Then, using silicone material, a double-sided rubber ring is prepared on the disc by casting. Then, the piston structure is assembled into the cylinder wall, and the rubber ring and the cylinder wall can be lubricated by silicone oil.

[0088] Preparation of the lid: A suitable lid is prepared by injection molding using PMMA material and then assembled onto the adsorption box body 10.

[0089] The self-adsorption box assembly provided in this embodiment includes a box body 10, an adsorption component 20, and an air extraction component 30. The box body 10 has a first mounting cavity. The adsorption component 20 includes a self-adsorption membrane 21 and a plurality of support columns 22. The self-adsorption membrane 21 is disposed in the first mounting cavity and forms an air extraction space in the first mounting cavity. The plurality of support columns 22 are spaced apart in the air extraction space to support the self-adsorption membrane 21. The side of the self-adsorption membrane 21 facing away from the support columns 22 is used to adsorb the object to be adsorbed 01. The air extraction component 30 is connected to the air extraction space through a connecting pipe 31. When the air extraction component 30 extracts air, the self-adsorption membrane 21 is partially embedded in the gap between the support columns 22. The self-adsorption membrane 21 located inside the box body 10 adsorbs the workpiece 01 to be adsorbed, which can prevent damage to the workpiece 01 during transportation or storage and achieve protection of the workpiece 01. Furthermore, the gas in the suction space is extracted by the suction component 30, so that the self-adsorption membrane 21 is partially embedded in the gap between the support columns 22, reducing the suction force between the self-adsorption membrane 21 and the workpiece 01 to be adsorbed, improving the convenience of removing the workpiece 01 from the self-adsorption membrane 21, avoiding damage to the workpiece during the removal process, and improving the removal efficiency of the workpiece.
