Description

Technical Field

[0001] This application relates to the field of vacuum adsorption technology, and particularly to a vacuum adsorption device. Background Art

[0002] Vacuum adsorption technology is widely used in multiple fields, such as: the production of precision camera modules, automation and robotics, packaging, etc. The vacuum adsorption device uses a vacuum pump to extract the air inside the suction nozzle, making the air pressure inside the suction nozzle less than the external atmospheric pressure, thus generating an internal and external pressure difference. The adsorption force generated by this pressure difference enables the suction nozzle to adsorb on the surface of an object, achieving the fixation and handling of the object.

[0003] Existing vacuum adsorption devices are configured with elastic members to provide a fixed buffering force, and it is difficult to adapt to various application scenarios and adsorb objects to be adsorbed of different material types. Since different objects to be adsorbed have different surface hardness, elasticity, and friction coefficients, for objects to be adsorbed with low surface hardness or poor elasticity, if the buffering force between the suction nozzle and the object to be adsorbed is too large, it may cause excessive extrusion of the surface of the object to be adsorbed during the adsorption process, thereby damaging the object to be adsorbed. For objects to be adsorbed with relatively high surface hardness and low friction, if the buffering force between the suction nozzle and the object to be adsorbed is too small, it may cause the suction nozzle to not fully fit the surface of the material, reducing the adsorption capacity of the vacuum adsorption device, or causing the object to be adsorbed to fall off the suction nozzle.

Detailed implementation manners

[0056] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to 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, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0057] In the present application, the orientation or positional relationship indicated by terms such as "upper", "lower", "top", "bottom", "inner", etc. is based on the orientation or positional relationship shown in the accompanying drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit that the indicated device, element or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0058] Moreover, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to specific circumstances.

[0059] In addition, the terms "install", "set", "provided with", "connect", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is an internal connection between two devices, elements or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0060] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0061] The vacuum adsorption device can be connected to complex devices such as a vacuum pump. The vacuum adsorption device includes a suction nozzle, and the suction nozzle can extract the air between it and the object to be adsorbed, so that the air pressure between the suction nozzle and the object to be adsorbed is less than the external atmospheric pressure, thereby generating an adsorption force so that the suction nozzle can adsorb on the surface of the object to achieve the fixation and handling of the object.

[0062] In order to enhance the adaptability of the suction nozzle during the adsorption process, so as to better form a seal with the surface of the object to be adsorbed and at the same time slow down the impact force that may be generated during the adsorption and release processes, the vacuum adsorption devices in the related art are often configured with elastic members. The elastic member can cause the suction nozzle to produce appropriate deformation when contacting the object to be adsorbed and generate a necessary buffering force for the adsorption process.

[0063] However, the existing vacuum adsorption devices are difficult to adapt to a variety of application scenarios and adsorb objects to be adsorbed of the same material type. Since different objects to be adsorbed have different surface parameters, such as hardness, elasticity and friction coefficient, for objects to be adsorbed with low surface hardness or poor elasticity, if the buffering force between the suction nozzle and the object to be adsorbed is too large, it may cause excessive extrusion of the surface of the object to be adsorbed during the adsorption process, thereby damaging the object to be adsorbed. For objects to be adsorbed with relatively high surface hardness and low friction, if the buffering force between the suction nozzle and the object to be adsorbed is too small, it may cause the suction nozzle to not fully conform to the surface of the material, reducing the adsorption capacity of the vacuum adsorption device, or causing the object to be adsorbed to fall off the suction nozzle.

[0064] To solve the above problems, the inventor studied the limitations of the existing vacuum adsorption devices, improved the existing vacuum adsorption devices, and designed a vacuum adsorption device with adjustable buffering force. Specifically, the vacuum adsorption device includes a sleeve, an adjusting member, a first positioning structure, an adsorption assembly, etc. The vacuum adsorption device can control the contact force between the suction nozzle and the surface of the object to be adsorbed by adjusting the buffering force, ensuring the stability of the contact force between the suction nozzle and the surface of the object to be adsorbed. The adjustable buffering force can enable the vacuum adsorption device to ensure the stability of the contact force between the suction nozzle and the object to be adsorbed when adsorbing different objects to be adsorbed, prevent potential damage to the surface of the object to be adsorbed caused by excessive extrusion, and at the same time ensure reliable adsorption effect and avoid the problem of the object to be adsorbed falling off due to insufficient adsorption force.

[0065] The technical solutions of the present application will be further described below in conjunction with embodiments and drawings.

[0066] Please refer to Figure 1 、 Figure 2 and Figure 3 as shown, Figure 1 which is one of the structural schematic diagrams of the vacuum adsorption device 01 provided by the embodiment of the present application; Figure 2 which is the second structural schematic diagram of the vacuum adsorption device 01 provided by the embodiment of the present application; Figure 3 is Figure 2Cross-sectional view of the vacuum adsorption device 01 in the A-A direction. An embodiment of the present application discloses a vacuum adsorption device 01 including: a sleeve 10, a receiving cavity 101 is formed inside the sleeve 10, a first elastic member 50 is arranged in the receiving cavity 101, and the first elastic member 50 can deform along the axial direction of the sleeve 10; an adjusting member 20, the adjusting member 20 is axially movably connected to the sleeve 10, the adjusting member 20 has a first air guiding channel 201, and at least a part of the adjusting member 20 extends into the receiving cavity 101 and abuts against the first end of the first elastic member 50; a first positioning structure 40, arranged between the adjusting member 20 and the sleeve 10, when the adjusting member 20 moves axially to any position, the first positioning structure 40 can axially fix the adjusting member 20 to the sleeve 10; an adsorption assembly 30, axially movably connected to the sleeve 10, the adsorption assembly 30 has a second air guiding channel 3011, at least a part of the adsorption assembly 30 extends into the receiving cavity 101 and abuts against the second end of the first elastic member 50, and the second air guiding channel 3011 communicates with the first air guiding channel 201.

[0067] The sleeve 10 is a tubular structure with an internal space. The receiving cavity 101 is an axially extending receiving space arranged inside the sleeve 10. The receiving cavity 101 forms a long strip-shaped space, so that the receiving cavity 101 can accommodate the adjusting member 20, the first positioning structure 40, the first elastic member 50 and at least a part of the adsorption assembly 30, and allows the adjusting member 20 and the adsorption assembly 30 to move or adjust their positions in the axial direction. The receiving cavity 101 is an independent space inside the sleeve 10, isolated from the external environment of the sleeve 10, which helps to protect the components in the receiving cavity 101 from external environmental interference, such as dust, moisture or corrosive gases, etc.

[0068] The adjusting member 20 can be axially movably connected to the sleeve 10, and at least a part of the adjusting member 20 can move axially in the receiving cavity 101 and abut against the first end of the first elastic member 50 located in the receiving cavity 101. In this way, when the adjusting member 20 moves axially, the length of the adjusting member 20 extending into the receiving cavity 101 is different, which can adjust the deformation amount of the first elastic member 50, thereby adjusting the magnitude of the deformation force generated by the first elastic member 50.

[0069] When the first elastic member 50 is subjected to an external force, it can expand and contract along the axial direction of the sleeve 10 and return to its original shape after the external force is withdrawn. When subjected to an external force, the first elastic member 50 can be compressed, converting the energy impact generated by the adsorption assembly 30 into gradually released energy, thereby producing a buffering effect. Among them, the first elastic member 50 can be a spring or an elastic rubber or other elastic members that can buffer external forces, and this embodiment does not limit this.

[0070] Compressing the first elastic member 50 by the adjusting member 20 can cause the first elastic member 50 to generate a pre-compression amount, so that the force generated by the deformation of the first elastic member 50 acts on the adsorption assembly 30. When it is necessary to suck the adsorbed object, the adsorption assembly 30 contacts and presses the surface of the object to be adsorbed, and the reaction force of the surface of the object to be adsorbed on the adsorption assembly 30 will compress the first elastic member 50 to form a buffering force. At this time, the deformation of the first elastic member 50 comes from two aspects: the force applied by the adjusting member 20 to the first elastic member 50, and the force acting on the adsorption assembly 30 from the surface of the object to be adsorbed when adsorbing the object to be adsorbed.

[0071] It can be understood that when the adjusting member 20 does not compress the first elastic member 50, the adsorption assembly 30 will abut against and compress the first elastic member 50 when adsorbing the object to be adsorbed, causing the first elastic member 50 to generate elastic deformation. At this time, if the object to be adsorbed to be adsorbed by the vacuum adsorption device 01 remains unchanged, the buffering force generated by the first elastic member 50 is usually a constant force. If the adjusting member 20 moves axially into the accommodation cavity 101 and compresses the first elastic member 50 to increase the deformation amount of the first elastic member 50 and generate a pre-compression force, then when the adsorption assembly 30 adsorbs the object to be adsorbed, the buffering force generated by the first elastic member 50 includes the above-mentioned constant force and the pre-compression force. By controlling the length of the adjusting member 20 extending into the accommodation cavity 101, an ideal pre-compression force that conforms to the surface parameters of the object to be adsorbed can be obtained, so as to achieve the effect of adjusting the buffering force generated by the vacuum adsorption device 01 according to the different surface parameters of the object to be adsorbed, thereby improving the adsorption adaptability of the vacuum adsorption device 01.

[0072] The first positioning structure 40 is arranged between the adjusting member 20 and the sleeve 10 and is located in the accommodation cavity 101. The first positioning structure 40 can realize the positioning of the adjusting member 20 in the sleeve 10 to ensure that the adjusting member 20 can be stably fixed on the sleeve 10 after moving axially along the sleeve 10 to the required position, preventing the position deviation of the adjusting member 20 caused by factors such as the vibration and impact of the vacuum adsorption device 01, so as to ensure that the pre-compression force generated when the first elastic member 50 is compressed by the adjusting member 20 is relatively stable.

[0073] Optionally, the first positioning structure 40 can be the cooperation of a positioning pin and a positioning hole. The positioning pin and the positioning hole are respectively arranged on the adjusting member 20 and the sleeve 10, and the positioning is realized through the cooperation of the positioning pin and the positioning hole. Threads that cooperate with each other can also be respectively arranged on the adjusting member 20 and the sleeve 10, and the movement and positioning of the adjusting member 20 are realized through the thread cooperation.

[0074] The adjusting member 20 is further provided with a first air guide channel 201 for connecting the vacuum tube of the vacuum generating device. The adsorption assembly 30 is used for adsorbing the object to be adsorbed. A second air guide channel 3011 communicated with the first air guide channel 201 is arranged in the adsorption assembly 30 to realize the flow of gas in the adsorption assembly 30 and achieve the effect of adsorbing the object to be adsorbed. When the adsorption assembly 30 adsorbs the object to be adsorbed, the adsorption assembly 30 will further extend into the tube sleeve 10 to compress the second end of the first elastic member 50, further changing the deformation amount of the first elastic member 50, so that a seal is formed between the adsorption assembly 30 and the surface of the object to be adsorbed, making the pressure in the first air guide channel 201 and the second air guide channel 3011 lower than the external atmospheric pressure, thereby adsorbing the object to be taken on the vacuum adsorption device 01.

[0075] Exemplarily, when adsorbing an object to be adsorbed with a large difference in surface hardness (for example, a thin glass), the adjusting member 20 can be axially away from the first elastic member 50, thereby reducing the deformation amount of the first elastic member 50 to achieve the purpose of reducing the buffer force, reducing the pressure of the adsorption assembly 30 on the object to be adsorbed, and avoiding damage to the object to be adsorbed; when adsorbing an object to be adsorbed with a high surface hardness and a small friction coefficient (for example, a steel plate), the adjusting member 20 can further compress the first elastic member 50, increasing the deformation amount of the first elastic member 50, thereby increasing the pre-compression force generated by the deformation of the first elastic member 50 to achieve the purpose of increasing the buffer force to ensure that the object to be adsorbed can be stably adsorbed.

[0076] In this way, the vacuum adsorption device 01 provided by the embodiment of the present application can change the pre-compression force applied by the adjusting member 20 to the first elastic member 50 by changing the position of the adjusting member 20 when adsorbing different objects to be adsorbed, thereby changing the buffer force that the first elastic member 50 may generate. While ensuring the stability of the adsorption force between the adsorption assembly 30 and the object to be adsorbed, it avoids damage to the surface of the object to be adsorbed caused by excessive extrusion of the adsorption assembly 30 on the object to be adsorbed.

[0077] As an optional implementation manner, as Figure 4 、 Figure 5 、 Figure 6 and Figure 7 shown, Figure 4 is one of the structural schematic diagrams of the adjusting member 20 provided by the embodiment of the present application; Figure 5 is Figure 4 the sectional view of the adjusting member 20 in the present application along the B-B direction; Figure 6 is the structural schematic diagram of the tube sleeve 10 provided by the embodiment of the present application; Figure 7 is Figure 6Cross-sectional view of the sleeve 10 in the C-C direction. The adjusting member 20 includes a connecting portion 202 that can extend into the accommodating cavity 101. The first positioning structure 40 includes a first internal thread 401 provided on the inner wall of the accommodating cavity 101 and a first external thread 402 provided on the outer surface of the connecting portion 202; the connecting portion 202 is cooperatively connected to the sleeve 10 through the first external thread 402 and the first internal thread 401.

[0078] The adjusting member 20 includes a connecting portion 202 that can extend into the accommodating cavity 101. The connecting portion 202 can extend along the axial direction of the sleeve 10. At the same time, one end of the connecting portion 202 can abut against one end of the first elastic member 50. The connecting portion 202 moves axially along the sleeve 10 in the accommodating cavity 101, which can cause deformation of the first elastic member 50 to adjust the magnitude of the pre-compressive force generated by the first elastic member 50.

[0079] Exemplarily, when the length of the connecting portion 202 extending into the accommodating cavity 101 is relatively long, the force exerted by the connecting portion 202 on the first elastic member 50 is relatively large, which can increase the deformation amount of the first elastic member 50 and increase the pre-compressive force, thereby increasing the possible buffering force generated by the vacuum adsorption device 01. Exemplarily, when the length of the connecting portion 202 extending into the accommodating cavity 101 is relatively short, the force exerted by the connecting portion 202 on the first elastic member 50 decreases, the deformation amount of the first elastic member 50 decreases, and the buffering force of the vacuum adsorption device 01 decreases.

[0080] The first internal thread 401 is a thread structure located on the inner wall of the accommodating cavity 101, and the first external thread 402 is a thread structure provided on the outer surface of the connecting portion 202 relative to the first internal thread 401. The first internal thread 401 and the first external thread 402 are cooperatively provided. The first internal thread 401 provides a mating surface for the first external thread 402, so that the connecting portion 202 can be fixed in the accommodating cavity 101, thereby ensuring that the adjusting member 20 reaches and remains at the required position without moving, and further ensuring the stability of the compressive force generated by the first elastic member 50. During the connection process, the spiral shape of the first internal thread 401 can also play a guiding role to ensure that the connecting portion 202 is screwed into the accommodating cavity 101 along a predetermined trajectory.

[0081] Further, please refer to Figure 5 , the adjusting member 20 further includes a main body portion 203 connected to the connecting portion 202. The main body portion 203 is located outside the accommodating cavity 101. The first air guiding channel 201 penetrates through the main body portion 203 and the connecting portion 202; in the radial direction of the sleeve 10, the size of the main body portion 203 is larger than the size of the connecting portion 202.

[0082] It can be understood that the main body portion 203 is the part connected to the connecting portion 202. The main body portion 203 and the connecting portion 202 are integrally formed. The main body portion 203 is located outside the accommodating cavity 101, and the connecting portion 202 fixes the main body portion 203 to the tube sleeve 10 together.

[0083] The first air guiding channel 201 penetrates through the main body portion 203 and the connecting portion 202 to ensure that gas can pass through the first air guiding channel 201 through the connecting portion 202 and the main body portion 203.

[0084] The size of the main body portion 203 is larger than that of the connecting portion 202. Thus, the main body portion 203 can play a certain limiting role when adjusting the position, preventing the main body portion 203 from further entering the accommodating cavity 101, restricting the maximum deformation amount of the first elastic member 50. At the same time, the relatively large size of the main body portion 203 provides a larger operating space and installation area, increasing the stability and load-bearing capacity of the adjusting member 20, and helping the adjusting member 20 to maintain stability outside the accommodating cavity 101.

[0085] It should be noted that please refer to Figure 8 、 Figure 9 and Figure 10 , Figure 8 which is one of the structural schematic diagrams of the adsorption assembly 30 provided by the embodiment of the present application; Figure 9 which is another structural schematic diagram of the adsorption assembly 30 provided by the embodiment of the present application; Figure 10 is Figure 9 the cross-sectional view of the adsorption assembly 30 in the adsorption assembly 30 along the D-D direction in. The air guiding rod 301, at least a part of the air guiding rod 301 extends into the accommodating cavity 101, and the second air guiding channel 3011 is arranged axially in the air guiding rod 301; the suction nozzle 302 is arranged at the end of the air guiding rod 301 outside the accommodating cavity 101, and the adsorption surface of the suction nozzle 302 is communicated with the second air guiding channel 3011.

[0086] It can be understood that the air guiding rod 301 can be a rod-shaped component. At least a part of the air guiding rod 301 extends into the accommodating cavity 101, so as to achieve the purpose of connecting the first air guiding channel 201 and the second air guiding channel 3011, and realize the flow of gas in the vacuum adsorption device 01. The other part of the air guiding rod 301 is located outside the accommodating cavity 101 and is used to connect the suction nozzle 302. Thus, the vacuum generating device can suck vacuum through the first air guiding channel 201 and the second air guiding channel 3011, form a negative pressure state between the object to be adsorbed and the suction nozzle 302, and complete the process of adsorbing the object to be adsorbed through the action of air pressure.

[0087] The suction nozzle 302 is disposed at the end of the air guide rod 301 outside the accommodation cavity 101 and is connected to the end of the second air guide channel 3011. The suction nozzle 302 has an adsorption surface, which is the part where the vacuum adsorption device 01 contacts the object to be adsorbed. The adsorption surface of the suction nozzle 302 is connected to the second air guide channel 3011. When the suction nozzle 302 contacts the object to be adsorbed and generates an adsorption force, gas can be inhaled or discharged through the second air guide channel 3011.

[0088] It should be noted that, please refer back to Figure 3 , a part of the air guide rod 301 extends into the first air guide channel 201. The fact that a part of the air guide rod 301 extends into the first air guide channel 201 can ensure the connection between the first air guide channel 201 and the second air guide channel 3011, and ensure the gas connectivity of the entire vacuum adsorption device 01.

[0089] As an alternative embodiment, please refer to Figure 7 and Figure 8 , the sleeve 10 includes a through port 102 connected to the accommodation cavity 101. The air guide rod 301 extends into the accommodation cavity 101 through the through port 102. The adsorption assembly 30 further includes: a limiting portion 303, the limiting portion 303 is disposed on the air guide rod 301, the dimension of the limiting portion 303 in the radial direction is larger than the caliber of the through port 102, the limiting portion 303 is located in the accommodation cavity 101, and the limiting portion 303 abuts against the first elastic member 50 in the axial direction.

[0090] The through port 102 is an opening at the axial end of the sleeve 10 for connecting the accommodation cavity 101 with the external space. The dimension and shape design of the through port 102 can be determined according to the shape and dimension of the air guide rod 301. The dimension of the through port 102 should allow the air guide rod 301 to pass through the through port 102. When the air guide rod 301 extends into the accommodation cavity 101 through the through port 102, the second air guide channel 3011 inside the air guide rod 301 can be connected to the gas environment in the accommodation cavity 101, thereby allowing gas to flow between the air guide rod 301 and the accommodation cavity 101.

[0091] The limiting portion 303 is disposed on the air guide rod 301, and the radial dimension of the limiting portion 303 is larger than the caliber of the through port 102 to ensure that the limiting portion 303 cannot escape from the accommodation cavity 101 through the through port 102, thereby playing a role in restricting the moving range of the air guide rod 301.

[0092] The limiting portion 303 is located within the accommodating cavity 101 and abuts against the first elastic member 50. By the abutment between the limiting portion 303 and the first elastic member 50, the axial movement of the adsorption assembly 30 can be transmitted to the first elastic member 50. Exemplarily, when the suction nozzle 302 adsorbs the object to be adsorbed, the limiting portion 303 on the air guide rod 301 moves towards the first elastic member 50, increasing the force on the first elastic member 50, increasing the deformation of the first elastic member 50, and causing the suction nozzle 302 to closely fit the surface of the object to be adsorbed.

[0093] Further, as Figure 10 shown, a seal 304 is provided between the limiting portion 303 and the first elastic member 50, and the edge of the seal 304 is sealingly abutted against the side wall of the accommodating cavity 101.

[0094] It can be understood that the seal 304 can prevent gas from leaking out of the accommodating cavity 101, ensure the negative pressure environment in the accommodating cavity 101, ensure the sealing stability between the suction nozzle 302 and the object to be adsorbed, and thus achieve the effect of stable adsorption.

[0095] As an alternative embodiment, as Figure 11 shown, Figure 11 is an exploded schematic view of the vacuum adsorption device 01 provided by the embodiment of the present application. One end of the first air guide channel 201 away from the accommodating cavity 101 is used to connect to a vacuum tube. The vacuum adsorption device 01 further includes: a clamping assembly 60, which is arranged on the side of the adjusting member 20 away from the tube sleeve 10, and the clamping assembly 60 is used to clamp the vacuum tube.

[0096] In the vacuum adsorption device 01, the first air guide channel 201, as the part connecting the vacuum generating device and the accommodating cavity 101, one end of the first air guide channel 201 away from the accommodating cavity 101 is used to connect to a vacuum tube to ensure that the negative pressure gas generated by the vacuum generating device can enter the accommodating cavity 101 through the vacuum tube and the first air guide channel 201 and communicate with the second air guide channel 3011, thereby realizing the adsorption function.

[0097] The clamping assembly 60 is arranged on the side of the adjusting member 20 away from the tube sleeve 10, and the clamping assembly 60 is used to clamp the vacuum tube. After the vacuum tube is installed in the first air guide channel 201 of the adjusting member 20, the clamping assembly 60 can prevent the vacuum tube from falling off or loosening due to vibration, impact, etc. during operation. At the same time, the clamping assembly 60 can connect the vacuum tube and the adjusting member 20, so that the vacuum tube moves synchronously with the vacuum adsorption device 01, ensuring the smooth completion of the adsorption process.

[0098] As an alternative embodiment, please refer to Figure 11 and Figure 12 , Figure 12FIG. 0 is one of the schematic structural diagrams of the support base 601 provided by the embodiments of the present application. The clamping assembly 60 includes: a support base 601 disposed on a side of the adjusting member 20 away from the tube sleeve 10. The support base 601 has a clamping cavity 6011 allowing a vacuum tube to pass through, and the clamping cavity 6011 communicates with the first air guide channel 201; a clamping member 602 slidably disposed on the support base 601 in the radial direction. The clamping member 602 can slide between a clamping position and an unlocking position. When the clamping member 602 moves to the clamping position, the clamping member 602 can extend out of the inner wall 6011a of the clamping cavity to clamp the vacuum tube. When the clamping member 602 moves to the unlocking position, the clamping member 602 is separated from the vacuum tube; a driving member 603 disposed on the adjusting member 20, and the driving member 603 is used to drive the clamping member 602 to move towards the clamping position and / or the unlocking position.

[0099] It can be understood that the support base 601 is disposed on a side of the adjusting member 20 away from the tube sleeve 10. The support base 601 provides a clamping cavity 6011 allowing a vacuum tube to pass through, and the clamping cavity 6011 communicates with the first air guide channel 201, ensuring that the vacuum tube can transmit gas to the first air guide channel 201. The inner wall 6011a of the clamping cavity faces the vacuum tube, and the outer wall 6011b of the clamping cavity faces the installation cavity 204 of the adjusting member 20.

[0100] The clamping member 602 is used to clamp the vacuum tube, and the clamping member 602 can move radially within a certain range of the support base 601. The clamping member 602 has two working positions: a clamping position and an unlocking position. When the clamping member 602 moves to the clamping position, the clamping member 602 will extend out of the inner wall 6011a of the clamping cavity and clamp the vacuum tube. In this way, the vacuum tube is fixed within the clamping assembly 60 and thus connected to the first air guide channel 201 of the adjusting member 20 to ensure the sealing performance and stability of the vacuum adsorption device 01. When the clamping member 602 moves to the unlocking position, the clamping member 602 will be separated from the vacuum tube, so that the vacuum tube is separated from the first air guide channel 201. The clamping member 602 switches between the above two working positions to clamp or loosen the vacuum tube.

[0101] To realize the change of the working position of the clamping member 602, the vacuum adsorption device 01 is equipped with a driving member 603. The driving member 603 is disposed on the adjusting member 20, and the driving member 603 can drive the clamping member 602 to move between the clamping position and the unlocking position. In this way, the working position of the clamping member 602 can be adjusted by operating the driving member 603 to realize the clamping and loosening between the clamping assembly 60 and the vacuum tube.

[0102] As an alternative embodiment, please refer to Figure 13 and Figure 14 , Figure 13The second structural schematic diagram of the support base 601 of the vacuum adsorption device 01 provided by the embodiment of the present application; Figure 14 is Figure 13 The sectional view of the support base 601 in [reference document] along the E-E direction. The clamping assembly 60 further includes: a reset member 604, and the reset member 604 is used to apply a reset force to the clamping member 602 in a direction opposite to the driving force direction of the driving member 603.

[0103] When the driving member 603 stops applying the driving force to the clamping member 602, the reset member 604 can use its own elasticity to pull the clamping member 602 back to the unlocking position. It is not necessary to manually operate the clamping member 602 to achieve reset, which improves the operation efficiency.

[0104] Exemplarily, when the driving member 603 moves to the clamping position, the driving member 603 squeezes the clamping member 602 to drive the clamping member 602 to move into the clamping cavity 6011, so that the clamping member 602 compresses the reset member 604 and causes the reset member 604 to generate elastic deformation. When the driving member 603 releases the squeezing force on the clamping member 602, the reset member 604 applies a reset force to the clamping member 602, thereby pushing the clamping member 602 out of the clamping cavity 6011 to achieve the purpose of loosening the vacuum tube.

[0105] Among them, the reset member 604 can be a spring, an elastic element or other structural members that may form a reset, and the present embodiment does not limit this.

[0106] As an optional implementation manner, please refer to Figure 15 , Figure 16 and Figure 17 , Figure 15 The structural schematic diagram of the driving member 603 of the vacuum adsorption device 01 provided by the embodiment of the present application; Figure 16 The second structural schematic diagram of the adjusting member 20 provided by the embodiment of the present application; Figure 17 is Figure 16 The sectional view of the adjusting member 20 in [reference document] along the F-F direction. An installation cavity 204 is formed on the side of the adjusting member 20 away from the tube sleeve 10, the support base 601 is arranged in the installation cavity 204, and a gap E is formed between the outer wall 6011b of the clamping cavity and the inner wall 204a of the installation cavity. When the clamping member 602 is in the unlocking position, a part of the clamping member 602 is located at the gap E; the driving member 603 is axially movably arranged at one end of the adjusting member 20 away from the tube sleeve 10, and the driving member 603 includes a pressing portion 6031 that can extend into the gap E. When the pressing portion 6031 moves into the gap E, the pressing portion 6031 can squeeze the clamping member 602 located at the gap E to make the clamping member 602 move to the clamping position.

[0107] On one side of the adjusting member 20 facing away from the sleeve 10, an installation cavity 204 is designed to accommodate the support seat 601. The support seat 601 is installed in the installation cavity 204 to provide support for the support seat 601. A certain gap E is maintained between the outer wall 6011b of the clamping cavity and the inner wall 204a of the installation cavity. This gap E allows the driving member 603 to be inserted into this gap E so that the clamping member 602 can move between the unlocking position and the clamping position.

[0108] When the clamping member 602 is in the unlocking position, a part of the clamping member 602 will be located at the gap E to ensure that the clamping member 602 does not completely block or restrict the passage of the vacuum tube in the unlocked state, thereby allowing the vacuum tube to be inserted or removed.

[0109] The driving member 603 includes a pressing portion 6031 that can extend into the gap E. The pressing portion 6031 is the part where the driving member 603 abuts against the clamping member 602. When the pressing portion 6031 moves into the gap E, the pressing portion 6031 will contact the clamping member 602 located at the gap E and apply a pressure along the axial direction of the clamping member 602 to move the clamping member 602 towards the clamping position, causing the clamping member 602 to move towards the clamping position.

[0110] In some embodiments, as Figure 15 shown, a guiding structure 605 is formed between the part of the clamping member 602 located in the gap E and the pressing portion 6031. The guiding structure 605 is configured to convert a part of the axial pressing force of the pressing portion 6031 into a driving force for pushing the clamping member 602 to move radially.

[0111] The guiding structure 605 is arranged between the part located in the gap E and the pressing portion 6031. The guiding structure 605 can guide the movement directions of the pressing portion 6031 and the clamping portion. When the pressing portion 6031 moves axially into the gap E along the sleeve 10, the guiding structure 605 decomposes the originally axial pressing force into a component continuing along the axial direction and a component along the radial direction. The component along the radial direction makes the clamping member 602 move towards the clamping position. By controlling the axial movement of the driving member 603, the clamping operation of the clamping member 602 can be realized without adjusting or calibrating the clamping member 602.

[0112] In some embodiments, please refer to Figure 15 and Figure 18 , Figure 18 which is a schematic structural diagram of the clamping member 602 of the vacuum adsorption device 01 provided by the embodiment of the present application. The guiding structure 605 includes a guiding inclined surface 6051 provided on the pressing portion 6031 and / or a guiding arc surface 6052 provided at the end of the clamping member 602 located in the gap E.

[0113] The guiding inclined surface 6051 is located on the side of the extrusion part 6031 that contacts the clamping part 602. When the extrusion part 6031 moves axially, the guiding inclined surface 6051 will contact the clamping part 602, causing the clamping part 602 to move towards the clamping position. The guiding arc surface 6052 is located at the end of the clamping part 602 within the gap E. The guiding arc surface 6052 enables the clamping part 602 to move to a predetermined clamping position when subjected to the axial force of the extrusion part 6031. The guiding inclined surface 6051 and the guiding arc surface 6052 can be used in combination or separately, and this embodiment does not limit this.

[0114] As an alternative embodiment, please refer back to Figure 17 , a plurality of clamping parts 602 are provided on the side wall of the clamping cavity 6011 in the circumferential direction, and the extrusion part 6031 is configured such that when the extrusion part 6031 moves into the gap E, the extrusion part 6031 can simultaneously extrude a plurality of clamping parts 602.

[0115] The plurality of clamping parts 602 are circumferentially distributed and can simultaneously apply clamping forces to the vacuum tube from multiple directions, which helps prevent the vacuum tube from shifting or tilting during clamping and ensures the stability of clamping. According to different clamping requirements, the number, distribution, and clamping force magnitude of the clamping parts 602 can be adjusted to meet vacuum tubes of different shapes, sizes, and weights.

[0116] In some embodiments, as Figure 15 shown, the extrusion part 6031 is configured as a tubular structure having a hollow cavity 6032. The hollow cavity 6032 of the extrusion part 6031 is used to accommodate the support base 601, enhancing the stability of the support base 601.

[0117] The tubular structure of the extrusion part 6031 is used to cooperate with the gap E so that the extrusion part 6031 can extend into the gap E to achieve the purpose of extruding the clamping part 602.

[0118] As an alternative embodiment, please refer back to Figure 11 , the clamping assembly 60 further includes: a second positioning structure 606, which is arranged between the driving part 603 and the adjusting part 20. When the driving part 603 moves to any position, the second positioning structure 606 can fix the driving part 603 to the adjusting part 20.

[0119] The second positioning structure 606 can ensure the fixing requirement of the driving member 603 when it moves to the target position. When the driving member 603 moves axially under the action of external power, the driving member 603 will drive the extrusion portion 6031 to move together. When the extrusion portion 6031 moves to the required position, the second positioning structure 606 will fix the driving member 603 to the adjusting member 20 to ensure that the extrusion portion 6031 of the driving member 603 will not move due to factors such as gravity and vibration. The second positioning structure 606 ensures the stability of the driving member 603 at the target position, thereby improving the clamping effect of the entire clamping assembly 60.

[0120] As an alternative embodiment, please refer back to Figure 5 and Figure 15 , the second positioning structure 606 includes a second internal thread 6061 provided on the inner wall 204a of the installation cavity and a second external thread 6062 provided on the outer surface of the extrusion portion 6031; the extrusion portion 6031 is connected to the installation cavity 204 through the second external thread 6062 and the second internal thread 6061 in a mating manner.

[0121] When the extrusion portion 6031 is driven by the driving member 603 to move into the installation cavity 204, the second external thread 6062 on the outer surface of the extrusion portion 6031 will engage with the second internal thread 6061 on the inner wall 204a of the installation cavity. The cooperation between the second external thread 6062 and the second internal thread 6061 can fix the extrusion portion 6031 in the installation cavity 204. When it is necessary to release the clamping or adjust the clamping position, the driving member 603 can be rotated in the reverse direction to separate the second external thread 6062 from the second internal thread 6061, so as to realize the movement of the extrusion portion 6031.

[0122] As an alternative embodiment, please refer to Figure 19 , Figure 20 and Figure 21 , Figure 19 is a schematic structural diagram of removing the clamping member 602 from the support seat 601 provided in the embodiment of the present application; Figure 20 is Figure 19 a cross-sectional view of the support seat 601 in Figure 21Schematic diagram of the plugging member 6014 provided for the example of this application. An installation groove 6012 with a notch 6012a facing the inner wall 204a of the installation cavity is provided on the support base 601. The plugging member 6014 is arranged at the notch 6012a of the installation groove 6012. A first through hole 6013 is formed on the bottom wall 6012b of the installation groove 6012. A second through hole 6015 is formed on the plugging member 6014. Both ends of the clamping member 602 can respectively extend out of the first through hole 6013 or the second through hole 6015. An abutting portion 6021 is formed on the clamping member 602, and the radial dimension of the abutting portion 6021 is larger than that of the first through hole 6013 and the second through hole 6015. The reset member 604 is a spring. The reset member 604 is sleeved on the clamping member 602, and both ends of the reset member 604 respectively abut against the abutting portion 6021 and the bottom wall 6012b of the installation groove 6012.

[0123] The installation groove 6012 is located on the support base 601, and the notch 6012a of the installation groove 6012 faces the inner wall 204a of the installation cavity. The installation groove 6012 provides an installation space for the clamping member 602 and the reset member 604. The plugging member 6014 is installed at the notch 6012a of the installation groove 6012 to close a part of the installation groove 6012. The second through hole 6015 formed on the plugging member 6014 allows the clamping member 602 to extend out at the unlocking position.

[0124] The first through hole 6013 is located on the bottom wall 6012b of the installation groove 6012 and is a channel for the clamping member 602 to extend out for clamping operation. The second through hole 6015 is located on the plugging member 6014 and provides an extending path for the clamping member 602 in the opposite direction to the first through hole 6013. When it is necessary to clamp the vacuum tube, the driving member 603 acts on the clamping member 602, so that one end of the clamping member 602 extends out through the first through hole 6013, and the clamping member 602 can clamp the vacuum tube. When it is necessary to adjust the installation position of the vacuum tube or disassemble the vacuum tube from the driving member 603, the pressing portion 6031 of the driving member 603 releases the abutment against the clamping member 602, and the reset member 604 releases the reset force, pushing the clamping member 602 to move out of the installation groove 6012 through the second through hole 6015 until the clamping member 602 returns to the unlocking position.

[0125] As an alternative implementation, please refer back to Figure 20 , a third internal thread 6012c is formed in the installation groove 6012, and a third external thread 6014a is formed on the outer surface of the plugging member 6014. The plugging member 6014 is connected to the installation groove 6012 by matching the third internal thread 6012c and the third external thread 6014a.

[0126] It can be understood that a third internal thread 6012c is machined on the inner wall of the installation groove 6012, and a third external thread 6014a is machined on the outer surface of the plugging member 6014. The third external thread 6014a corresponds to the third internal thread 6012c in the installation groove 6012. By rotating the plugging member 6014, the third external thread 6014a interacts with the third internal thread 6012c to realize the connection between the plugging member 6014 and the installation groove 6012. The plugging member 6014 is connected to the installation groove 6012, so that the plugging member 6014 provides an abutting surface for the reset member 604.

[0127] As an alternative embodiment, as Figure 17 shown, the adjusting member 20 further includes a limit seat 205. The limit seat 205 is located in the installation cavity 204 and is arranged around the first air guide channel 201. The support seat 601 is located between the limit seat 205 and the inner wall 204a of the installation cavity.

[0128] The limit seat 205 is located in the installation cavity 204 and is arranged around the first air guide channel 201. The limit seat 205 provides a platform for positioning the support seat 601. By being arranged around the first air guide channel 201, the limit seat 205 can limit the movement range of the support seat 601 in the installation cavity 204 and prevent the support seat 601 from shifting or tilting during operation.

[0129] Optionally, the limit seat 205 and the adjusting member 20 are integrally formed to form an integral structure, which helps to enhance the structural strength of the limit seat 205.

[0130] The support seat 601 is located between the limit seat 205 and the inner wall 204a of the installation cavity. The support seat 601 is jointly supported by the limit seat 205 and the inner wall 204a of the installation cavity to ensure the stability of the support seat 601.

[0131] As an alternative embodiment, please refer back to Figure 11 , the vacuum adsorption device 01 further includes: a locking assembly 70, which is arranged on the adjusting member 20 and the sleeve 10. The locking assembly 70 locks the adjusting member 20 and the sleeve 10 to limit the rotation of the adjusting member 20 relative to the sleeve 10.

[0132] The locking assembly 70 is arranged on the adjusting member 20 and the sleeve 10 to prevent the adjusting member 20 from loosening or falling off relative to the sleeve 10, ensuring the stability of the vacuum adsorption device 01 during operation. The locking assembly 70 is easy to unlock and lock, and relevant components can be conveniently operated when maintenance or adjustment of the vacuum adsorption device 01 is required.

[0133] The locking assembly 70 is used to fix the compression amount of the first elastic member 50. Although the adjusting member 20 and the sleeve 10 are already fixed by threads, the threads are prone to loosening.
