[0026] Unless the context clearly requires otherwise, the words "include", "comprising" and similar words throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, the meaning is "including but not limited to".

[0027] In the description of this application, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0028] The present application provides an adsorption base. Figure 1 It is a schematic diagram of the overall structure of the embodiment of the present application. Figure 1 The adsorption base of this embodiment includes a main body 10, and a plurality of air holes 11 are arranged on the main body 10. The plurality of air holes 11 are interconnected, and a sealing sleeve 20 is arranged in each air hole 11. A gas through hole 21 connected to the bottom of the air hole 11 is vertically arranged in the sealing sleeve 20 to ensure that the air hole 11 is connected to the outside to achieve adsorption of the carrier. When the carrier is adsorbed on the adsorption base, the sealing sleeve 20 in the air hole 11 can effectively improve the stability of the carrier on the adsorption base, thereby reducing the friction caused by the displacement of the carrier, extending the service life of the adsorption base, and reducing the generation of debris, thereby ensuring the quality of the final product.

[0029] Figure 5 is a schematic diagram of the bottom structure of this embodiment, Figure 2 is a cross-sectional view of the gas passage, Figure 3 is a cross-sectional view of a sealing sleeve 20 provided in the air hole 11, Figure 4 It is a cross-sectional view of the fixing hole.

[0030] Reference Figure 1 The main body 10 is a rectangular parallelepiped, and a plurality of air holes 11 are regularly arranged on the main body 10 . A sealing sleeve 20 is provided in each air hole 11 , and the gas through hole 21 in the sealing sleeve 20 is vertically connected to the bottom of the air hole 11 .

[0031] Reference Figure 1 and Figure 3 , the top of the sealing sleeve 20 and the top of the air hole 11 are located in the same plane. Therefore, when the carrier is adsorbed, the sealing sleeve 20 will not affect the contact between the carrier and the main body 10, so that the carrier can be completely fitted with the main body 10. This makes the contact between the carrier and the main body 10 closer, reduces the gap between the two, and thus avoids the occurrence of vacuum leakage. In addition, the contact area between the carrier and the main body 10 is also relatively increased, which enhances the stability when the carrier is adsorbed, thereby reducing the friction caused by the movement of the carrier. The reduced friction between the main body 10 and the carrier helps to extend the service life of the adsorption base. At the same time, the debris generated by friction is also reduced, which effectively improves the product quality.

[0032] Reference Figure 3 The top of the sealing sleeve 20 is set to be dish-shaped. The dish shape is slightly concave in the center and has a flat edge, and is shaped like a shallow dish or a plate. Figure 3 The top of the sealing sleeve 20 is set to be disc-shaped, the center part is slightly concave and the bottom is connected to the gas through hole 21, and the edge part is kept flush with the upper surface of the body 10. This design enables the sealing sleeve 20 to better adapt to the slight unevenness of the carrier surface, providing stronger adsorption force and better sealing effect.

[0033] Furthermore, when the carrier is adsorbed, the carrier and the sealing sleeve 20 are also closely fitted, which can effectively increase the static friction of the carrier, further ensuring the stability of the carrier when adsorbed. At the same time, the sealing sleeve 20 will be slightly deformed as the carrier is squeezed, making the sealing sleeve 20 and the carrier closer, so as to ensure the airtightness during adsorption and avoid the occurrence of air leakage.

[0034] Optionally, the sealing sleeve 20 may be made of rubber material, or other materials such as composite materials.

[0035] Reference Figure 3 , the air hole 11 is a step-shaped blind hole that is larger at the top and smaller at the bottom. The sealing sleeve 20 can be blocked in the air hole 11 to prevent the sealing sleeve 20 from moving downward due to suction when the workpiece is adsorbed, thereby affecting the air tightness between the carrier plate and the adsorption base. In addition, the shape of the sealing sleeve 20 matches the shape of the air hole 11, and the sealing sleeve 20 and the air hole 11 are tightly matched. The sealing sleeve 20 fits tightly in the air hole 11, further ensuring the stability of the sealing sleeve 20 in the air hole 11, while avoiding the appearance of a gap between the sealing sleeve 20 and the air hole 11 to cause air leakage.

[0036] Reference Figure 3 The main body 10 is provided with a gas passage 12, which is arranged below the gas holes 11 and communicates with all the gas holes 11. Figure 2The gas passage 12 includes a transverse passage 121 and a plurality of parallel longitudinal passages 122. The transverse passage 121 is vertically cross-connected with the longitudinal passage 122, and one end of the transverse passage 121 is connected to the outside to connect to equipment such as an air pump or a vacuum pipe. The plurality of air holes 11 are symmetrically arranged with the transverse passage 121 as the symmetry axis, and each longitudinal passage 122 is connected to two symmetrically arranged air holes 11, so that each air hole 11 is connected to the gas passage 12, thereby ensuring the stability of vacuum adsorption.

[0037] Reference Figure 1 The plurality of air holes 11 on the body 10 are evenly spaced and arranged in a matrix. Figure 2 , the transverse passage 121 is arranged in the middle of the multiple exhaust holes 11, referring to Figure 2 , a connection port 123 is provided at one end of the transverse passage 121. The connection port 123 is located on the side of the body 10 and is connected to the outside of the body 10 for connecting to equipment such as an air pump or a vacuum pipe. The other end of the transverse passage 121 extends into the inside of the body 10 and is connected to the longitudinal passage 122. Figure 3 , each longitudinal passage 122 is evenly spaced corresponding to the position of the air hole 11, and is connected to the bottom of the upper air hole 11. In this way, multiple air holes 11 are interconnected through the transverse passage 121 and the longitudinal passage 122. The transverse passage 121 and the longitudinal passage 122 are both arranged along a straight line, which greatly reduces the difficulty of processing the gas passage 12 when making the adsorption base. In addition, the transverse passage 121 and the longitudinal passage 122 are symmetrically arranged below the air hole 11 corresponding to the air hole 11, which helps to ensure that the gas flow is evenly distributed between each air hole 11 and ensure the stability during vacuum adsorption.

[0038] Optionally, the gas passage 12 may also be arranged in other ways, such as being arranged in a ring shape around the air hole 11 .

[0039] When actually processing the gas passage 12 in the body 10, the transverse passage 121 runs through the entire body 10, and one end of each longitudinal passage 122 is connected to the outside. This processing method is simple and fast, and greatly reduces the production cost. In actual application, the connection port 123 at one end of the transverse passage 121 is connected to the air suction device, and the opening at the other end of the transverse passage 121 and the opening end of each longitudinal passage 122 are sealed to prevent air leakage.

[0040] And, the distribution of the pores 11 and the distance between adjacent pores 11 are set according to the specific application. In this embodiment, the carrier board adsorbed and fixed has a hollow structure. When the carrier board is placed on the adsorption base, the minimum distance between the sealing sleeve 20 and the hollow structure of the carrier board is 3 mm. Keeping a certain distance between the pores 11 and the hollow structure can avoid gas leakage during vacuum adsorption, so as to ensure the stability of vacuum adsorption.

[0041] It is understandable that the air holes 11 can also be arranged in other ways or sizes according to the specific structure of the carrier or other workpieces. For example, the upper air hole 11 can be arranged between two air holes 11 in the next row, and the distribution of the air passages 12 can also be adjusted accordingly.

[0042] Reference Figure 1 , Figure 2 and Figure 5 , the body 10 is provided with a workpiece positioning hole 13. In this embodiment, the body 10 is provided with two workpiece positioning holes 13, and the workpiece positioning holes 13 penetrate the body 10. Figure 2 The workpiece positioning hole 13 is located at the outermost side of the cross section of the body 10 and is arranged symmetrically with respect to the center point of the body 10, so as to facilitate observation of whether the carrier is aligned with the workpiece positioning hole 13. The setting of the workpiece positioning hole 13 facilitates the rapid and accurate placement of the carrier, and ensures that the hollow structure on the carrier and the air hole 11 can maintain a suitable distance.

[0043] Optionally, the number and positions of the workpiece positioning holes 13 are set correspondingly according to the specific structure of the carrier plate or other workpieces.

[0044] Reference Figure 1 , Figure 2 and Figure 5 , horizontal adjustment holes 14 are symmetrically arranged on the main body 10. A matching supporting structure (not shown in the figure) is arranged in the horizontal adjustment hole 14, and the supporting structure is connected in the horizontal adjustment hole 14. When placing the adsorption base, the height of the corresponding position on the main body 10 can be adjusted by adjusting the length of the supporting structure extending from the bottom of the main body 10, and then the overall horizontality of the main body 10 can be adjusted to ensure that the adsorption base is placed horizontally, which is convenient for positioning and adsorption of the carrier plate. Four horizontal adjustment holes 14 are arranged on the main body 10 of this embodiment, and the four horizontal adjustment holes 14 are located at the outermost sides of the air holes 11, and are arranged symmetrically with respect to the center point of the main body 10. The centrally symmetrical arrangement ensures the balance in the position distribution of the horizontal adjustment holes 14, and this balance helps to improve the stability of the overall structure of the adsorption base.

[0045] Optionally, the number and positions of the horizontal adjustment holes 14 can also be set according to specific needs, and the support structure and the horizontal adjustment holes 14 can be connected by thread or interference fit.

[0046] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The main body 10 is provided with a fixing hole 15. A fastener (not shown in the figure) is provided in the fixing hole 15. In this embodiment, four fixing holes 15 are provided on the main body 10, and the fixing holes 15 are arranged symmetrically with respect to the center point of the main body 10. This ensures that the main body 10 is evenly stressed when being fixed, thereby improving the stability of the adsorption base itself. Figure 1 and Figure 5 The four fixing holes 15 are respectively arranged close to the four horizontal adjustment holes 14, which can reduce the errors that may occur during the adjustment process and improve the adjustment accuracy.

[0047] Optionally, the number and positions of the fixing holes 15 can also be set according to specific requirements.

[0048] Reference Figure 1 A side of the body 10 is provided with a space-avoiding portion 16 to avoid the sensors and other equipment used to detect the position of the carrier. Also, the connection port 123 of the gas passage 12 is located on the side of the body 10 opposite to the space-avoiding portion 16 to avoid the pipe connected to the connection port 123 from blocking the sensor. Optionally, the connection port 123 can also be set at the middle position of the bottom of the body 10 or other positions.

[0049] The adsorption base of the embodiment of the present application improves the stability of the carrier when it is adsorbed on the adsorption base by disposing a sealing sleeve in the air hole. The top surface of the sealing sleeve and the top surface of the main body are located in the same plane. The carrier can fit with the main body when adsorbed, which effectively improves the stability of the carrier, thereby reducing the friction between the carrier and the main body, extending the service life of the adsorption base, and also reducing debris generated by friction, thereby ensuring the quality of the final product.
