[0003] For different sizes of PCB, the existing adsorption table top generally fixes different preset sizes of PCB in the mode of table top cavity separation. Specifically, the adsorption table top is separated into multiple cavities, and the size of each cavity corresponds to different preset sizes of PCB. When adsorbing, the preset size of PCB is placed at the cavity consistent with its size. This adsorption mode can avoid the connection of the air suction hole not covered by the PCB with the atmosphere, thereby forming a stable vacuum value.

[0103] In other possible embodiments, the related parameters can be dynamically adjusted according to actual conditions.

[0104] In an embodiment, the second driving member 9 further comprises a second guide member, which is installed on the second housing 8 and extends along the second direction y.

[0105] The second partition is in sliding connection with the second guide member.

[0106] The second guide member can provide sliding guidance for the second partition along the second direction y, so as to ensure the movement of the second partition along the second direction y.

[0107] In an embodiment, the adsorption device further comprises a second position detection assembly, which is arranged on the second partition and is used to detect the position of the second partition relative to the second cavity.

[0108] In an embodiment, the second position detection assembly comprises a second sensing member and a second sensor 10. The second sensing member is installed on the second partition, and the second sensor 10 is installed on the second housing 8.

[0109] The second sensing member can move synchronously with the second partition along the second direction y, so as to approach or move away from the second sensor 10.

[0110] The position of the second partition is obtained by sensing the second sensing member by the second sensor 10.

[0111] In an embodiment, the second sensing member can be a magnetic member, and the second sensor 10 can be a magnetic switch, so as to confirm the position of the second partition by magnetic sensing. By using the magnetic sensing mode, the opening on the second housing 8 can be reduced, so as to ensure the air tightness.

[0112] In an embodiment, as shown in Figure 1 Fig. 6, the adsorption device further comprises a second vacuum pipe 11, which is installed on the second housing 8 and is in communication with the second vacuum hole.

[0113] The second vacuum pipe 11 is used to connect the vacuum device, so as to realize the communication between the vacuum device and the fourth cavity.

[0114] In an embodiment, as shown in Figure 1 and Figure 2 The body 1 comprises a first layer plate 107 and a second layer plate 108 arranged in a stack, the first adsorption cavity 102 and the second adsorption cavity 104 are arranged between the first layer plate 107 and the second layer plate 108, the first communication hole 103 and the second communication hole 105 are arranged on the first layer plate 107, and the first adsorption hole 101 and the second adsorption hole 109 are arranged on the second layer plate 108, thereby forming the body 1.

[0116] In an embodiment, the size of the first layer plate 107 is 620mm x 720mm, and the thickness is 10mm. The first layer plate 107 is made of aluminum alloy material, which has good heat conductivity and corrosion resistance.

[0117] The surface material of the second layer plate 108 is a flame-resistant material (FR-4 grade flame-resistant material), and the thickness is 1.6mm.

[0118] In an embodiment, as shown in Figure 3 , the radial section of the first adsorption hole 101 is circular. The first adsorption hole 101 comprises a first hole section and a second hole section connected in communication. The second hole section is located at the end of the first hole section away from the first layer plate 107, and the diameter of the second hole section is greater than that of the first hole section.

[0119] In this way, the diameter of the end of the first adsorption hole 101 (i.e. the first hole section) in communication with the first adsorption cavity 102 is smaller, so as to reduce the gas leakage of the uncovered area of the first adsorption cavity 102 when the plate covers a certain first adsorption cavity 102, and to ensure the overall air tightness. At the same time, the diameter of the end of the first adsorption hole 101 close to the plate (i.e. the second hole section) is larger, which can increase the adsorption area and make the adsorption effect better.

[0120] In an embodiment, as shown in Figure 3 , the diameter of the first hole section is 0.3mm-0.7mm, and the diameter of the second hole section is 1mm-2mm. Preferably, the diameter of the first hole section is 0.5mm, and the diameter of the second hole section is 2mm.

[0121] By designing the diameters of the first hole section and the second hole section, the adsorption effect can be ensured while the air tightness is ensured.

[0122] In an embodiment, as shown in Figure 3As shown, the radial section of the second adsorption hole 109 is circular, and the second adsorption hole 109 comprises a third hole segment and a fourth hole segment connected in series, and the fourth hole segment is located at one end of the third hole segment away from the first layer plate 107, and the diameter of the fourth hole segment is larger than that of the third hole segment.

[0123] Thus, the diameter of the end of the second adsorption hole 109 (i.e. the third hole segment) connected to the second adsorption cavity 104 is small, so as to reduce the gas leakage of the uncovered area of the second adsorption cavity 104 when the plate covers a certain second adsorption cavity 104, and ensure the overall air tightness. At the same time, the diameter of the end of the second adsorption hole 109 close to the plate (i.e. the fourth hole segment) is large, which can increase the adsorption area and make the adsorption effect better.

[0124] In an embodiment, as shown, the diameter of the third hole segment is 0.3mm-0.7mm, and the diameter of the fourth hole segment is 1mm-2mm. Preferably, the diameter of the third hole segment is 0.5mm, and the diameter of the fourth hole segment is 2mm. Figure 3 The diameters of the first hole segment and the second hole segment are designed to ensure the air tightness and the adsorption effect.

[0125] In an embodiment, as shown, the plurality of first adsorption holes 101 and the plurality of second adsorption holes 109 are arranged at intervals, such as in a matrix arrangement in the body 1. The distance between adjacent two first adsorption holes 101 is 10mm-20mm, and / or the distance between adjacent two second adsorption holes 109 is 10mm-20mm, and / or the distance between adjacent first adsorption hole 101 and second adsorption hole 109 is 10mm-20mm. Preferably, the distance between adjacent two first adsorption holes 101 is 15mm, the distance between adjacent two second adsorption holes 109 is 15mm, and the distance between adjacent first adsorption hole 101 and second adsorption hole 109 is 15mm.

[0126] Figure 1 The distance between adjacent two adsorption holes is designed to ensure the adsorption effect.

[0127] Through testing, when the diameter of the first hole segment is 0.5mm, the diameter of the second hole segment is 2mm, and the distance between adjacent two adsorption holes 101 is 15mm, the gas leakage rate of the body 1 is less than 1x10^-3 Pa·m^3 / s.

[0128] In an embodiment, each adsorption hole 101 is made by laser drilling technology, which has good uniformity and consistency.

[0129] In an embodiment, each adsorption hole 101 is made by laser drilling technology, which has good uniformity and consistency.
