[0025] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] like Figures 1 to 3 As shown, an embodiment of the present invention provides an adsorption assembly, including a fixing plate 1 and an elastic adsorption member, wherein the fixing plate 1 has a mounting hole 3 penetrating the fixing plate 1 along a first direction;

[0027] The elastic adsorbent has a vent hole inside for gas to pass through, and the elastic adsorbent can adsorb materials through the vent hole;

[0028] One end of the elastic adsorbent is located within the mounting hole 3, while the end surface of the other end protrudes from the mounting hole 3. In this embodiment, the adsorption assembly is primarily used in the field of circuit board processing. The elastic adsorbent is capable of adsorbing items such as stickers onto the circuit board. The first direction is the thickness direction of the fixing plate 1. The end surface of the elastic adsorbent located outside the mounting hole 3 protrudes from the side surface of the fixing plate 1 by 0.2 mm to 0.8 mm, for example, 0.5 mm. The vent design allows for effective air passage. Combined with the elastic properties of the elastic adsorbent, the pressure within the elastic adsorbent can be quickly adjusted, thereby quickly and effectively adsorbing materials. The elastic adsorbent's compressive deformation capability reduces the flatness requirements of the fixing plate 1 and the mounting hole 3, which helps improve component compatibility and reduces the risk of material removal failure due to inaccurate flatness. The protruding end surface design allows the elastic adsorbent to slightly protrude from the fixing plate 1 when uncompressed, which helps ensure closer contact between the elastic adsorbent and the material. This not only improves the stability and efficiency of material removal, but also reduces manufacturing and maintenance costs, making the entire material removal process more economical, reliable, and efficient.

[0029] In one embodiment, the elastic suction component includes a suction rod 4 and an elastic suction cup 2. The suction rod 4 is installed in the mounting hole 3. One end of the elastic suction cup 2 is located in the mounting hole 3, and the other end of the elastic suction cup 2 protrudes from the mounting hole 3. One end of the suction rod 4 is connected to the fixing plate 1, and the other end of the suction rod 4 is connected to the elastic suction cup 2. The vent includes a first vent and a second vent. The elastic suction cup 2 has a first vent inside, and the suction rod 4 has a second vent for gas to pass through. The first vent is connected to the second vent. In this embodiment, the axis of the first vent, the axis of the second vent, and the axis of the mounting hole 3 are parallel or coincident. The elastic suction cup 2 is made of a soft material, such as a silicone elastic suction cup 2 or an accordion elastic suction cup 2. The suction rod 4 is designed with a second vent inside, which is connected to the first vent of the elastic suction cup 2. This design helps to improve the sealing performance of the suction component. By providing the suction rod 4, the suction component can adapt to suction nozzles of different specifications, improving the versatility and flexibility of the component. This design allows the adsorption assembly to be used in a variety of different application scenarios without having to individually design and manufacture the fixing plate 1 and the mounting hole 3 for each specification of the suction nozzle, thereby reducing the complexity of design and manufacturing.

[0030] In one embodiment, the elastic suction cup 2 and the fixing plate 1 are each detachably connected to the suction rod 4. This design, by making the elastic suction cup 2 and the fixing plate 1 detachably connected to the suction rod 4, allows for easy adaptation to suction nozzles of varying specifications and sizes, enhancing the versatility and flexibility of the suction assembly. This detachable connection design allows for separate inspection and maintenance of each component of the suction assembly without disrupting the overall structure, facilitating timely identification and resolution of problems and improving overall system reliability.

[0031] In one embodiment, the mounting hole 3 includes a first hole section 31 and a second hole section 32 that are connected, and the suction rod 4 has a first connecting portion 41 and a second connecting portion 42 that are connected. The first connecting portion 41 is located in the first hole section 31, and the second connecting portion 42 is located in the second hole section 32.

[0032] The suction rod 4 is detachably connected to the fixed plate 1 via the first connection portion 41, and the suction rod 4 is detachably connected to the elastic suction cup 2 via the second connection portion 42. In this embodiment, by designing the elastic suction cup 2 and the fixed plate 1 to be detachably connected to the suction rod 4, maintenance and replacement operations can be performed quickly. When the elastic suction cup 2 or the suction rod 4 fails or wears out, there is no need to replace the entire assembly. Only the problematic part needs to be removed and replaced, which greatly saves maintenance time and cost. This design allows the adsorption assembly to adapt to different application scenarios. For example, when the suction nozzle needs to be replaced to accommodate materials of different sizes or shapes, only the old suction nozzle needs to be removed and a new one needs to be installed without replacing the entire assembly, thereby improving the adaptability and flexibility of the system. By adopting a detachable connection method, not only the efficiency of maintenance and replacement is improved, the adaptability and flexibility are enhanced, but also the sealing performance is improved, the manufacturing cost is reduced, and the reliability of the system is improved.

[0033] In one embodiment, the second connecting portion 42 is provided with a slot 421, and the elastic suction cup 2 is provided with a clip 21, which snaps into the slot 421. In this embodiment, the use of a detachable connection not only improves the reliability and sealing performance of the connection, but also facilitates quick disassembly and assembly, reduces maintenance costs, increases manufacturing flexibility, and enhances the user experience. The elastic suction cup 2 is provided with a flange at one end near the second connecting portion 42, which snaps into the slot 421. The second connecting portion 42 has a first and second enlarged portions spaced apart along its axial direction, forming a slot 421 between the first and second enlarged portions. This structure helps improve the seal between the elastic suction cup 2 and the suction rod 4, ensuring that airflow does not leak from the connection during material adsorption, thereby improving overall adsorption efficiency and performance. Furthermore, the clip 21 snaps into the slot 421. The cooperation between the flange and the slot 421 enhances the stability of the connection and reduces the risk of accidental detachment during the adsorption process.

[0034] In one embodiment, the first hole section 31 is a threaded hole, and the first connecting portion 41 includes a threaded section that is threadedly connected to the threaded hole. By designing the first hole section 31 as a threaded hole and threading the threaded section of the suction rod 4 thereinto, the connection reliability of the suction assembly can be improved. The threaded connection allows for fine-tuning of the position of the suction rod 4 to adapt to varying operating conditions or compensate for wear. This adjustability improves the adaptability and service life of the suction assembly.

[0035] In one embodiment, in a direction perpendicular to the first direction, the cross-sectional area of ​​the second hole segment 32 is greater than the cross-sectional area of ​​the first hole segment 31, and the cross-sectional area of ​​the end of the second connecting portion 42 proximate to the first connecting portion 41 is greater than the cross-sectional area of ​​the first hole segment 31. In this embodiment, the cross-sectional area of ​​the second hole segment 32 is greater than the cross-sectional area of ​​the first hole segment 31, and the cross-sectional area of ​​the end of the second connecting portion 42 proximate to the first connecting portion 41 is greater than the cross-sectional area of ​​the first hole segment 31. This design makes it easier for the suction rod 4 to be inserted and secured within the mounting hole 3. Due to the cross-sectional area design between the second connecting portion 42 and the first hole segment 31, the second connecting portion 42 is prevented from entering the first hole segment 31. This structure also allows the suction rod 4 to be compatible with elastic suction cups 2 of different specifications. Elastic suction cups 2 of different sizes or shapes can be quickly replaced to suit different application requirements, thereby improving the adaptability of the entire system to diverse operations. By optimizing the cross-sectional area of ​​the connection part and the hole section, not only the connection reliability and sealing performance are improved, but also the adjustment flexibility is enhanced, the manufacturing cost is reduced, the system reliability and operational safety are improved, and the production efficiency and flexibility are improved.

[0036] In one embodiment, a plurality of elastic adsorption members are provided, a plurality of mounting holes 3 are provided, and the plurality of mounting holes 3 are arranged on the fixing plate 1 along the second direction, and an elastic adsorption member is provided in each mounting hole 3;

[0037] The first direction is perpendicular to the second direction. In this embodiment, multiple mounting holes 3 are arranged along the second direction (lengthwise or widthwise) on the fixed plate 1, and each mounting hole 3 is provided with an elastic adsorbent. This design effectively utilizes the space on the fixed plate 1, and particularly improves space utilization when multiple elastic adsorbents are required to operate simultaneously. When elastic adsorbents of different specifications need to be replaced to accommodate different suction tasks, the modular design of the mounting holes 3 and the elastic adsorbents allows for quick replacement, improving work efficiency and the adaptability of the equipment. Each elastic adsorbent is installed in an independent mounting hole 3. This design helps ensure the stability and sealing of each elastic adsorbent, avoiding interference between elastic adsorbents that could affect the suction effect. Even if a problem occurs with one elastic adsorbent, it will not affect the normal operation of other elastic adsorbents, thereby improving the reliability and stability of the entire system.

[0038] In one embodiment, a vent groove 5 is provided on the fixing plate 1, and the mounting hole 3 is connected to the vent groove 5;

[0039] The vent grooves 5 are used to distribute gas to the elastic adsorbents in the mounting holes 3. In this embodiment, by providing the vent grooves 5 on the fixing plate 1 and connecting multiple mounting holes 3 to the vent grooves 5, it is possible to ensure that gas is evenly distributed to the elastic adsorbents in each mounting hole 3. This uniform distribution helps each elastic adsorbent generate a stable adsorption force, improving the adsorption performance and consistency of the entire adsorption assembly. Furthermore, compared to providing a separate ventilation duct for each elastic adsorbent, the design of the vent grooves 5 can reduce the number of ducts used, thereby reducing manufacturing costs and material consumption.

[0040] According to the adsorption assembly of the present invention, the elastic suction cup 2 is installed in the mounting hole 3 of the fixed plate 1, ensuring that one end is located inside the mounting hole 3 and the other end protrudes from the end face of the mounting hole 3 so as to be in direct contact with the material to be adsorbed. When the adsorption assembly is activated, airflow (negative pressure gas) is introduced through the first vent hole inside the elastic suction cup 2. Since the elastic suction cup 2 is elastic, it can be compressed and deformed when in contact with the material, so as to better fit the surface of the material, thereby forming a negative pressure between the elastic suction cup 2 and the material, generating a strong adsorption force, and firmly adsorbing the material on the elastic suction cup 2. By using elastic adsorption parts, the need for precise processing of the vent holes is reduced. The compression and deformation ability of the elastic suction cup 2 reduces the difficulty of material removal and the requirements for flatness, thereby reducing processing costs and reducing overall manufacturing costs.

[0041] In addition, one embodiment of the present invention provides a suction device comprising the suction assembly of the above-described embodiment. In this embodiment, the suction device further comprises a negative pressure structure capable of negatively pressurizing gas and a transport structure. During operation, the elastic suction cup 2 absorbs material through the first vent hole, utilizing the principle of air pressure differential to stably adhere the material to the elastic suction cup 2, and the transport structure facilitates material transport.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
