Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, 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 protection scope of the present application.

[0032] 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.

[0033] Moreover, in addition to being used to indicate orientation or positional relationship, some of the above terms may also be used to express 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 this application can be understood according to specific circumstances.

[0034] In addition, the terms "installed", "set up", "provided with", "connected", and "linked" 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 can be internal communication between two devices, components, or parts. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] In addition, terms such as "first", "second", etc. are mainly used to distinguish different devices, components, or parts (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, components, or parts. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0036] In the camera manufacturing industry, the vacuum adsorption technology ensures the precise positioning of the optical lens and the photosensitive sensor. Traditional vacuum adsorption devices often adopt a single-airway design, that is, both the negative-pressure air flow and the positive-pressure air flow flow through the same airway. The single airway can adsorb the lens or sensor by generating a negative-pressure air flow during the grasping stage. In this process, it is very easy to inhale foreign matters such as tiny particles and dust in the surrounding environment, and there may be some particles and dust remaining attached to the inner wall of the single airway. When the product needs to be placed, the positive-pressure air flow used to release the product has a lower pressure than the negative-pressure air flow, and foreign matters such as tiny particles and dust may be blown to the surface of the lens or sensor by the weaker positive-pressure air flow, causing contamination.

[0037] Pollutants such as tiny particles and dust reduce the optical performance and imaging quality of the lens and the sensor. As the core components of the camera, the surface cleanliness of the lens and the sensor is related to the clarity of imaging and the accuracy of color reproduction. When the lens and the sensor are contaminated by tiny foreign matters or dust, it will lead to a decline in imaging quality, such as blurring, increased noise, and reduced contrast, affecting the user experience and the market competitiveness of the product.

[0038] To solve the above problems, the inventor studied the limitations of the existing vacuum adsorption device, improved the existing vacuum adsorption device, and designed a vacuum adsorption device in which the positive-pressure air flow and the negative-pressure air flow flow through different airways, thereby preventing the dust or debris inhaled by the negative-pressure air flow from being blown back onto the workpiece to be detected by the positive-pressure air flow, achieving the purpose of improving the production quality and yield.

[0039] Based on this, an embodiment of the present application discloses a vacuum adsorption device, which can solve the problem that the single air duct of the traditional vacuum adsorption device affects the air flow cleanliness during suction and blowing.

[0040] Next, the technical solution of the present application will be further described in conjunction with the embodiments and the drawings.

[0041] Please refer to Figures 1 to 4 , Figure 1 which is one of the schematic structural diagrams of the vacuum adsorption device 100 provided by the embodiment of the present application. Figure 2 which is another schematic structural diagram of the vacuum adsorption device 100 provided by the embodiment of the present application. Figure 3 which is the schematic structural diagram of the air guiding assembly 2 provided by the embodiment of the present application. Figure 4 is Figure 3 the cross-sectional schematic diagram along the A-A direction in . An embodiment of the present application discloses a vacuum adsorption device 100, including: an adsorption assembly 1 for adsorbing an object to be adsorbed, and the adsorption assembly 1 includes a first air guiding channel 101; an air guiding assembly 2, the air guiding assembly 2 is sealingly connected to the adsorption assembly 1, the air guiding assembly 2 includes a second air guiding channel 201 and a third air guiding channel 202, and the second air guiding channel 201 and the third air guiding channel 202 communicate with the first air guiding channel 101; an air suction port 1a, which is arranged on the air guiding assembly 2, the air suction port 1a communicates with the second air guiding channel 201, and the air suction port 1a is used for communicating with a vacuum generating device; an air blowing port 1b, which is arranged on the air guiding assembly 2, the air blowing port 1b communicates with the third air guiding channel 202, and the air blowing port 1b is used for communicating with a gas source; a first check valve 201a, which is connected to the second air guiding channel 201, and the first check valve 201a allows negative pressure air flow to flow from the air suction port 1a to the adsorption assembly 1; a second check valve 202a, which is connected to the third air guiding channel 202, and the second check valve 202a allows positive pressure air flow to flow from the air blowing port 1b to the adsorption assembly 1.

[0042] The adsorption assembly 1 is used for adsorbing an object to be adsorbed. A first air guiding channel 101 is arranged inside the adsorption assembly 1. The first air guiding channel 101 transmits positive pressure air flow or negative pressure air flow to the surface of the adsorption assembly 1 in contact with the object to be adsorbed, so as to generate positive pressure or negative pressure between the object to be adsorbed and the adsorption assembly 1, so that a pressure difference is generated between the air pressure between the object to be adsorbed and the adsorption assembly 1 and the atmospheric pressure, so as to ensure that the atmospheric pressure can press or release the object to be adsorbed, and achieve the purpose of the adsorption assembly 1 adsorbing or releasing the object to be adsorbed.

[0043] Optionally, buffer components such as gaskets and rubber pads can be arranged on the surface of the adsorption assembly 1 in contact with the object to be adsorbed to prevent damage to the object to be adsorbed caused by the force generated by the adsorption assembly 1 on the object to be adsorbed.

[0044] The air guiding component 2 is hermetically connected to the adsorption component 1 to prevent the leakage of positive-pressure air flow or negative-pressure air flow between the air guiding component 2 and the adsorption component 1. The air guiding component 2 includes a second air guiding channel 201 and a third air guiding channel 202. The second air guiding channel 201 and the third air guiding channel 202 communicate with the first air guiding channel 101, so that the negative-pressure air flow in the second air guiding channel 201 and the positive-pressure air flow in the third air guiding channel 202 can be transmitted to the first air guiding channel 101, enabling the adsorption component 1 to complete the adsorption or release of the object to be adsorbed.

[0045] Optionally, the hermetic connection between the air guiding component 2 and the adsorption component 1 can be thread sealing, sealing ring sealing, sealant sealing, etc. This embodiment does not limit this.

[0046] The air suction port 1a is arranged on the air guiding component 2. One end of the air suction port 1a communicates with the second air guiding channel 201, and the other end of the air suction port 1a communicates with a vacuum generating device. The negative-pressure air flow generated by the vacuum generating device can enter the second air guiding channel 201 through the air suction port 1a, and then be transmitted to the first air guiding channel 101 through the second air guiding channel 201, so that the first air guiding channel 101 transmits the negative-pressure air flow to the surface of the adsorption component 1 in contact with the object to be adsorbed, achieving the purpose of adsorbing the object to be adsorbed.

[0047] The air blowing port 1b is arranged on the air guiding component 2. One end of the air blowing port 1b communicates with the third air guiding channel 202, and the other end of the air blowing port 1b communicates with a gas source. The positive-pressure air flow can enter the third air guiding channel 202 through the air blowing port 1b, and then be transmitted to the first air guiding channel 101 through the third air guiding channel 202, so that the first air guiding channel 101 transmits the positive-pressure air flow to the surface of the adsorption component 1 in contact with the object to be adsorbed, achieving the purpose of releasing the object to be adsorbed.

[0048] It can be understood that when it is necessary to adsorb the object to be adsorbed, the vacuum generating device generates a negative-pressure air flow and transmits the negative-pressure air flow into the second air guiding channel 201 through the air suction port 1a, and then the second air guiding channel 201 transmits the negative-pressure air flow to the first air guiding channel 101, so that a negative pressure is generated between the adsorption component 1 and the object to be adsorbed. At this time, the atmospheric pressure can press the object to be adsorbed against the surface of the adsorption component 1 in contact with the object to be adsorbed, thus completing the adsorption of the vacuum adsorption device 100 to the object to be adsorbed.

[0049] When it is necessary to place the object to be adsorbed, the positive-pressure air flow transmits the positive-pressure air flow into the third air guiding channel 202 through the air blowing port 1b, and then the third air guiding channel 202 transmits the positive-pressure air flow to the first air guiding channel 101, so that the negative pressure between the adsorption component 1 and the object to be adsorbed disappears. At this time, the atmospheric pressure releases the pressure on the object to be adsorbed, so that the adsorption component 1 releases the adsorption of the object to be adsorbed, completing the placement of the vacuum adsorption device 100 to the object to be adsorbed.

[0050] Optionally, a vacuum generating device is used to generate a negative pressure air flow and transmit it to the second air guide channel 201. When the vacuum generating device stops generating the negative pressure air flow, the third air guide channel 202 can communicate with the atmosphere so as to generate a positive pressure air flow in the third air guide channel 202. Or the third air guide channel 202 communicates with the vacuum generating device, and the vacuum generating device generates a positive pressure air flow and transmits it to the third air guide channel 202.

[0051] The first check valve 201a is connected to the second air guide channel 201, and the first check valve 201a allows the negative pressure air flow to move from the suction port 1a to the adsorption assembly 1. The first check valve 201a can allow the negative pressure air flow to pass through the first check valve 201a and be transmitted to the second air guide channel 201 when the vacuum generating device generates the negative pressure air flow, while when transmitting the positive pressure air flow, the positive pressure air flow cannot pass through the first check valve 201a, so that the second air guide channel 201 is used to transmit the negative pressure air flow, avoiding the positive pressure air flow flowing through the second air guide channel 201 to the first air guide channel 101.

[0052] The second check valve 202a is connected to the third air guide channel 202, and the second check valve 202a allows the positive pressure air flow to move from the blowing port 1b to the adsorption assembly 1. The second check valve 202a can allow the positive pressure air flow to pass through the second check valve 202a and be transmitted to the third air guide channel 202 when generating the positive pressure air flow, while when the vacuum generating device generates the negative pressure air flow, the negative pressure air flow cannot pass through the second check valve 202a, so that the third air guide channel 202 can be used to transmit the positive pressure air flow, avoiding the negative pressure air flow flowing through the second air guide channel 201 to the vacuum generating device.

[0053] The settings of the first check valve 201a and the second check valve 202a can enable the second air guide channel 201 and the third air guide channel 202 to be used to transmit the negative pressure air flow and the positive pressure air flow respectively, so as to achieve the purpose of transmitting the negative pressure air flow and the positive pressure air flow through different air guide channels. In this way, when adsorbing the object to be adsorbed, the dust and impurities inhaled by the negative pressure air flow will not be blown out by the positive pressure air flow, further ensuring that the inhaled dust and impurities will not fall back onto the object to be adsorbed again and ensuring the cleanliness of the object to be adsorbed.

[0054] Thus, when the vacuum adsorption device 100 provided by the embodiments of the present application adsorbs the object to be adsorbed, the second air guide channel 201 of the vacuum adsorption device 100 is connected to the negative pressure air flow, and the first check valve 201a prevents the negative pressure air flow from entering the third air guide channel 202, so that dust and impurities are sucked into the second air guide channel 201 and flow out of the vacuum adsorption device 100 through the second air guide channel 201. When the vacuum adsorption device 100 releases the object to be adsorbed, the positive pressure air flow passes through the third air guide channel 202, and the second check valve 202a prevents the positive pressure air flow from entering the second air guide channel 201, thereby preventing dust and impurities from being blown back to the object to be adsorbed 102, ensuring the cleanliness of the object to be adsorbed, and thus improving the yield and production efficiency of the object to be adsorbed.

[0055] Please refer to Figure 2 , in some embodiments, the vacuum adsorption device 100 includes: an air suction pipeline 3, one end of the air suction pipeline 3 is connected to the air suction port 1a, the other end of the air suction pipeline 3 is used to connect to a vacuum generating device, and the air suction pipeline 3 transmits the negative pressure air flow generated by the vacuum generating device to the adsorption assembly 1 and transmits the negative pressure air flow into the second air guide channel 201 through the air suction port 1a.

[0056] Optionally, the air suction pipeline 3 and the adsorption assembly 1 can be connected by an interface screw, a quick connector, or a flange. This embodiment does not limit this.

[0057] In addition, the air suction pipeline 3 can be made of materials such as stainless steel, polyvinyl chloride, or polyurethane to ensure that the air suction pipeline 3 can be used stably for a long time under the flow of negative pressure air flow, extend the service life of the vacuum adsorption device 100, and increase the reliability of the vacuum adsorption device 100.

[0058] The vacuum adsorption device 100 further includes a first filter 301, and the first filter 301 is disposed on the air suction pipeline 3. When adsorbing the object to be adsorbed, the vacuum generating device generates a negative pressure air flow, so that dust and impurities enter the second air guide channel 201, and then enter the air suction pipeline 3 through the second air guide channel 201. The first filter 301 can filter these dust and impurities to prevent the dust and impurities from entering the vacuum generating device, causing damage to the vacuum generating device or polluting the vacuum generating device, thereby ensuring the reliability and cleanliness of the vacuum generating device.

[0059] Optionally, the first filter 301 can adopt structures such as a metal mesh, a fiber cloth, and activated carbon that can filter the negative pressure air flow.

[0060] Please refer to Figure 2, in some embodiments, the vacuum adsorption device 100 includes: a first solenoid valve 302, which is disposed on the air suction pipeline 3 and located between the first filter 301 and the vacuum generating device. The first solenoid valve 302 is used to control the negative pressure air flow in the air suction pipeline 3. By opening or closing the first solenoid valve 302, it is possible to control whether the negative pressure air flow generated by the vacuum generating device is transmitted to the suction port 1a and the second air guide channel 201, thereby realizing the control of the adsorption process.

[0061] In the vacuum adsorption device 100, if the vacuum generating device operates for a long time, it may cause unnecessary wear or damage to the vacuum generating device. The first solenoid valve 302 can be closed when adsorption is not required, protecting the vacuum generating device, saving energy at the same time, and reducing the production cost of the object to be adsorbed.

[0062] Please refer to Figure 2 , in some embodiments, the vacuum adsorption device 100 includes: a blowing pipeline 4, one end of the blowing pipeline 4 is connected to the blowing port 1b, and the other end of the blowing pipeline 4 is used to connect to the vacuum generating device. The blowing pipeline 4 transmits the positive pressure air flow to the adsorption assembly 1 and transmits the positive pressure air flow into the third air guide channel 202 through the blowing port 1b.

[0063] Optionally, the blowing pipeline 4 and the adsorption assembly 1 can be connected by an interface screw, a quick connector, or a flange. This embodiment does not limit this.

[0064] In addition, the blowing pipeline 4 can be made of materials such as stainless steel, polyvinyl chloride, or polyurethane to ensure that the blowing pipeline 4 can be used stably for a long time under the condition of positive pressure air flow, extend the service life of the vacuum adsorption device 100, and increase the reliability of the vacuum adsorption device 100.

[0065] The vacuum adsorption device 100 further includes a second filter 401, which is disposed on the blowing pipeline 4. When it is necessary to release the object to be adsorbed, the positive pressure air flow is transmitted into the third air guide channel 202 through the blowing port 1b. The second filter 401 can filter dust and impurities in the positive pressure air flow, preventing dust and impurities from entering the adsorption assembly 1 and causing pollution to the third air guide channel 202 and the positive pressure air flow, thereby preventing dust and impurities from falling on the object to be adsorbed 102 and ensuring the cleanliness of the object to be adsorbed 102.

[0066] Optionally, the second filter 401 can adopt structures such as a metal mesh, a fiber cloth, and activated carbon that can realize the filtration of the negative pressure air flow.

[0067] Please refer to Figure 2, in some embodiments, the vacuum adsorption device 100 includes: a second solenoid valve 402, which is disposed on the blowing air pipeline 4 and located between the second filter 401 and the air source. The second solenoid valve 402 is used to control the positive pressure air flow in the blowing air pipeline 4. By opening or closing the second solenoid valve 402, it is possible to control whether the positive pressure air flow is transmitted to the blowing port 1b and the third air guiding channel 202, thereby realizing the control of the placement process of the object to be adsorbed 102.

[0068] In the vacuum adsorption device 100, if the vacuum generating device is in an operating state for a long time, it may cause unnecessary wear or damage to the vacuum generating device. The second solenoid valve 402 can be closed when it is not necessary to release the object to be adsorbed 102, protecting the vacuum generating device, saving energy at the same time, and reducing the production cost of the object to be adsorbed.

Optionally, the second mounting portion 2042 may be provided with an external thread, and the inside of the second air guiding member 206 is provided with an internal thread. The second mounting portion 2042 and the second air guiding member 206 are detachably connected by a thread.

[0073] The second air guide 206 is used to connect the air blowing channel and the air guide assembly 2, so as to transfer the positive pressure airflow in the air blowing channel to the third air guide channel 202 in the air guide assembly 2, thereby forming a complete flow path of the positive pressure airflow. At the same time, the second air guide 206 can prevent the positive pressure airflow from leaking between the air guide assembly 2 and the air blowing channel, thereby ensuring the working efficiency of the vacuum adsorption device 100.

[0074] The mounting member 204 further includes a third mounting portion 2043 , in which a connecting channel 203 is formed. The third mounting portion 2043 is detachably connected to the adsorption assembly 1 , and the connecting channel 203 is connected to the first air guiding channel 101 , the second air guiding channel 201 and the third air guiding channel 202 .

[0075] The third mounting portion 2043 connects the second air channel 201 and the third air channel 202 to the first air channel 101 through the connecting channel 203 formed inside, thereby improving the arrangement of the air channels inside the adsorbent 102, making rational use of the space inside the adsorbent 102, and miniaturizing the adsorbent 102.

[0076] The third mounting portion 2043 and the adsorption assembly 1 are connected in a detachable manner, so that when the vacuum adsorption device 100 is maintained, upgraded or the adsorption assembly 1 is replaced, the operation can be performed conveniently and quickly without disassembling the entire vacuum adsorption device 100.

[0077] Optionally, the third mounting portion 2043 and the adsorption component 1 may be connected by threads, for example, the third mounting portion 2043 is provided with external threads, the adsorption component 1 is provided with internal threads, and the third mounting portion 2043 and the adsorption component 1 are fixed by threaded connection. The third mounting portion 2043 and the adsorption component 1 may also be connected by sealing ring sealing connection, interference fit connection, etc., which is not limited in this embodiment.

[0078] See also Figure 7 , Figure 7 The third structural schematic diagram of the vacuum adsorption device 100 provided in the embodiment of the present application, in some embodiments, the adsorption component 1 includes an adsorption member 102, and the adsorption member 102 is used to adsorb the object to be adsorbed. At least part of the first air guide channel 101 is located in the adsorption member 102, so that the surface of the adsorption member 102 in contact with the object to be adsorbed can form a negative pressure, so that the adsorption member 102 adsorbs the object to be adsorbed.

[0079] The adsorption assembly 1 further includes a mounting seat 103 and a connecting rod 104 . The mounting seat 103 is connected to the adsorption component 102 . The connecting rod 104 is disposed on a side of the mounting seat 103 that is away from the adsorption component 102 .

[0080] The mounting seat 103 is used to connect the adsorption member 102 and the connecting rod 104, ensuring the overall stability and structural integrity of the adsorption assembly 1. The mounting seat 103 includes a protrusion 1031, and the protrusion 1031 includes a mounting surface 1031a, and the mounting surface 1031a is inclined relative to the axial direction of the connecting rod 104, and the air guide assembly 2 is arranged on the mounting surface 1031a. It can be understood that the mounting surface 1031a on the protrusion 1031 is inclined relative to the axial direction of the connecting rod 104, so that the installation position of the air guide assembly 2 is inclined relative to the axial direction of the connecting rod 104, so that the air guide assembly 2 will not interfere with the connecting rod 104, thereby ensuring the reliability of the overall structure of the vacuum adsorption device 100.

[0081] At least part of the first air guide channel 101 is located in the protrusion 1031, so that the first air guide channel 101 can be connected to the connecting channel 203 inside the air guide component 2 through the protrusion 1031, and positive pressure or negative pressure airflow is transmitted through the second air guide channel 201, the third air guide channel 202 and the connecting channel 203 in the air guide component 2.

[0082] See also Figure 7 , Figure 7 for Figure 6 In the cross-sectional schematic diagram along the BB direction, in some embodiments, the adsorbent 102 includes: a first connecting member 1022, the first connecting member 1022 is connected to the mounting seat 103, and the first air guide channel 101 passes through the first connecting member 1022. The first connecting member 1022 is the part connecting the adsorbent 102 and the mounting seat 103, and plays the role of fixing and supporting the adsorbent 102.

[0083] The adsorbent 102 further includes a second connecting member 1023, which is connected to the side of the first connecting member 1022 away from the mounting seat 103, and a connecting cavity 102c is formed in the second connecting member 1023, and the connecting cavity 102c is connected to the first air guide channel 101. The adsorbent 102 further includes a suction nozzle 1021, which is connected to the second connecting member 1023, and a plurality of suction ports are provided on the suction nozzle 1021, and the plurality of suction ports are connected to the connecting cavity 102c.

[0084] The connecting cavity 102c is used to transfer the positive pressure airflow or negative pressure airflow in the first air guide channel 101 to the multiple suction ports on the suction nozzle 1021, so that each suction port can receive the same positive pressure airflow or negative pressure airflow, ensuring that the suction force of the suction nozzle 1021 on the to-be-adsorbed part 102 is the same at each suction port. The setting of multiple suction ports disperses the suction force of the suction nozzle 1021 on the to-be-adsorbed part 102, thereby preventing the damage to the to-be-adsorbed part 102 caused by excessive single-point suction force, and also preventing the shaking or falling off of the to-be-adsorbed part 102 caused by uneven suction force of each suction port.

[0085] Optionally, the material of the suction nozzle 1021 can be rubber, ceramic, bakelite, tungsten steel, etc.

[0086] Please refer to Figure 8 and Figure 9 , Figure 8 which is the fourth structural schematic diagram of the vacuum adsorption device 100 provided by the embodiment of the present application. Figure 9 Figure 5 is the fifth structural schematic diagram of the vacuum adsorption device 100 provided by the embodiment of the present application. In some embodiments, the multiple adsorption ports include: a first adsorption port 102a, which is arranged on the surface of the suction nozzle 1021 for abutting against the object to be adsorbed. The first adsorption port 102a is communicated with the first air guide channel 101 and is used for adsorbing the object to be adsorbed. The central line of the first adsorption port 102a coincides with the axis of the connecting rod 104.

[0087] The first adsorption port 102a is arranged on the surface of the suction nozzle 1021 for abutting against the object to be adsorbed. When the suction nozzle 1021 approaches or contacts the object to be adsorbed, the first adsorption port 102a is the part directly facing and contacting the object to be adsorbed. The first adsorption port 102a is communicated with the first air guide channel 101 and can enable the positive-pressure air flow and the negative-pressure air flow to flow from the inside of the adsorbing member 102 to the outside.

[0088] The central line of the first adsorption port 102a coincides with the axis of the connecting rod 104. It can be understood that the first adsorption port 102a is located at the central position corresponding to the connecting rod 104, that is, the central position of the mounting seat 103, so as to improve the stability of the vacuum adsorption device 100 for adsorbing the adsorbing member 102.

[0089] Please refer to Figure 9 , in some embodiments, the multiple adsorption ports include: a plurality of second adsorption ports 102b, and the plurality of second adsorption ports 102b are located on the circumferential side of the first adsorption port 102a.

[0090] The plurality of second adsorption ports 102b increase the contact area between the adsorbing member 102 and the object to be adsorbed, thereby improving the adsorption effect. When the positive-pressure air flow or the negative-pressure air flow enters the communication cavity 102c through the first air guide channel 101 and finally flows out from each adsorption port, the plurality of second adsorption ports 102b can generate more adsorption points, making it easier for the object to be adsorbed to be adsorbed.

[0091] Since the second adsorption ports 102b are distributed around the first adsorption port 102a, a surrounding adsorption area can be formed, ensuring that the positive-pressure air flow or the negative-pressure air flow can be evenly distributed on the surface of the object to be adsorbed when flowing out, thereby improving the adsorption uniformity.

[0092] Meanwhile, multiple second adsorption ports 102b enable the adsorbent 102 to better adapt to objects to be adsorbed with different shapes and sizes. Whether the object to be adsorbed is a flat surface, a curved surface or has a complex shape, the adsorbent 102 can achieve effective adsorption through the cooperative action of multiple adsorption ports.

[0093] In addition, the design of multiple adsorption ports also improves the reliability of the system. Even if a certain adsorption port fails or becomes blocked, the other adsorption ports can still continue to work.

[0094] Please refer to Figure 8 , in some embodiments, the adsorption assembly 1 includes: a magnetic member 105 disposed on the side of the connecting rod 104 away from the mounting base 103. The magnetic member 105 is used to connect to a robotic arm, so that the vacuum adsorption device 100 can be fixed to an external robotic arm and move with the robotic arm to achieve efficient automated operation.

[0095] The magnetic member 105 can ensure the stability and reliability during the connection between the robotic arm and the vacuum adsorption device 100 by magnetic adsorption, reducing accidents caused by unstable connection.

[0096] Meanwhile, the magnetic connection method usually has a relatively fast switching speed. In cases where it is necessary to frequently replace the vacuum adsorption device 100 or adjust the operation position, the magnetic connection between the vacuum adsorption device 100 and the robotic arm can improve production efficiency and flexibility.

[0097] In addition, the magnetic connection can reduce wear caused by friction and contact, thereby extending the service life of the magnetic members 105 of the robotic arm and the vacuum adsorption device 100.

[0098] Embodiments of the second aspect of the present application provide a vacuum picking device, including: a robotic arm; a vacuum adsorption device 100, the vacuum adsorption device 100 is disposed on the robotic arm through a magnetic member 105; a vacuum generating device connected to the suction port 1a of the vacuum adsorption device 100, and a gas source connected to the blowing port 1b of the vacuum adsorption device 100.

[0099] Since the vacuum picking device provided by the embodiments of the present application includes the vacuum adsorption device 100 provided by the embodiments of the first aspect of the present application, therefore, the vacuum picking device has the beneficial effects of any of the above-mentioned vacuum adsorption devices 100, which will not be elaborated here.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
