In order to further understand the features and technical contents of the present invention, please refer to the following detailed description and drawings of the present invention. However, the drawings are only for reference and explanation, and are not intended to limit the creation.

Referring to FIG. 1 and FIG. 2, the present invention provides a vacuum adsorption platform 1 including a carrying platform 11, a base 12 and a gas line device 13.

First, the load-bearing platform 11 has a relatively high height in the middle, and the heights on both sides are relatively thin, and from the side angle, it is a shape resembling a convex shape. The portion of the carrying platform 11 on the front side of the center has a bearing surface 111, and the portions of the carrying platform 11 on the front sides of the two sides respectively have a side airfoil 117. The positioning block 112 can be placed on the side airfoil 117 on both sides of the carrying platform 11. After the positioning of the side air bearing surface 117, the positioning block 112 has a height slightly higher than the height of the bearing surface 111 to create a function of limiting the two sides of the bearing surface 111. . In addition, the materials used in the loading platform 11 and the positioning block 112 are stainless steel in this embodiment. However, the bearing platform 11 and the positioning block 112 may also be made of other metal materials. The materials of the loading platform 11 and the positioning block 112 are not limited. .

A plurality of air holes 113 are formed in the bearing surface 111, and the air holes 113 respectively penetrate the bearing platform 11, that is, the air holes 113 extend from the bearing surface 111 of the carrying platform 11 to the back surface 118 of the carrying platform 11. The vents on the bearing surface 111 113 can be selectively placed into the vent plug 114. In other words, some of the air holes 113 will be placed into the vent plug 114, while some of the air holes 113 will not be placed into the vent plug 114. The vent plug 114 has a passage for allowing air to flow in the middle, and communicates with both ends of the vent plug 114. Therefore, both ends of the vent plug 114 communicating are aligned into the air hole 113, so that the vent plug 114 Air can be circulated between the bearing surface 111 and the back surface 118 of the carrier platform 11.

The pedestal 12 is closely connected to the pedestal 12 , and the pedestal 12 is in the shape of a accommodating groove, that is, an accommodating space 121 is formed in the susceptor 12 . In addition, the material used for the susceptor 12 is stainless steel in this embodiment. However, the susceptor 12 may be made of other metal materials, and the material of the susceptor 12 is not limited. The second platform is provided with a plurality of second screw holes 123 at a position corresponding to the side of the back surface 118 of the load platform 11 , and a plurality of second screws are also disposed at corresponding positions of the base 12 . The hole 123 is locked between the carrying platform 11 and the second screw hole 123 of the base 12 through the second screw 124 to achieve the effect of firmly connecting the bearing platform 11 and the base 12. Further, the loading platform 11 is provided with six second screw holes 123 at the back surface 118 directly below the bearing surface 111, and six corresponding second screw holes 123 are also opened corresponding to the base 12, The second screw 124 is locked between the carrying platform 11 and the second screw hole 123 of the base 12, thereby achieving a tight engagement between the bearing platform 11 and the base 12. In addition, four second screw holes 123 are respectively defined in the back surface 118 directly below the side wing surfaces 117 of the two sides, and the two sides of the base 12 are respectively corresponding to four corresponding ones. The second screw hole 123 can fix the bearing platform 11 and the base 12 through the second screw 124, and the second screw 124 can also fix the positioning block 112 to the side airfoil surface 117.

In addition, two first screw holes 115 are formed on the bearing surface 111 , and the first screw holes 115 penetrate the bearing platform 11 to the back surface 118 . Two fixing members 122 are disposed in the accommodating space 121 of the susceptor 12 , and the fixing member 122 is integrally formed with the pedestal 12 , and the middle of the fixing member 122 has a threaded hole communicating with the back surface of the pedestal 12 . However, the number of the first screw holes 115 and the fixing members 122 may be plural, and the number thereof is not limited. The first screw 116 is locked between the first screw hole 115 and the fixing member 122, and the first screw 116 can pass through the fixing member 122 of the base 12 to reach the back surface of the base 12 to be locked to the machine device ( The figure is not shown).

A tape 119 may be disposed on the back surface 118 of the carrying platform 11, and the tape 119 has a plurality of openings 1191, wherein the openings 1191 respectively correspond to the air holes 113 into which the vent plug 114 is placed. In other words, if the air hole 113 of the carrying platform 11 is placed in the vent plug 114, the tape 119 opens a corresponding opening 1191 to allow air to pass therethrough, so that it can circulate air with the accommodating space 121 of the lower base 12. If the vent hole 113 is not placed in the vent plug 114, the air is blocked by the tape 119, so that the air of the air vent 113 cannot be circulated with the accommodating space 121 of the lower susceptor 12. Thereby, the air vent 113 having the vent plug 114 can be circulated by using the tape 119 having the plurality of openings 1191.

A gas line device 13 may be disposed at one end of the base 12, and a first gas channel 131 and a second gas channel 132 may be disposed, wherein the first gas channel 131 and the second gas channel 132 are respectively evacuated and The air intake device, however, does not limit which gas passage is used for pumping and intake air, and the gas passage for pumping and intake air can be determined according to actual needs. The purpose is to evacuate the gas in the accommodating space 121 of the susceptor 12 when the gas line device 13 performs the pumping, so that the air vent 113 placed in the vent plug 114 has The function of the suction cup thus allows the load-bearing surface 111 of the carrier platform 11 to function as a vacuum suction. When the gas line device 13 performs the intake air, the accommodating space 121 is refilled with air, and the bearing surface 111 of the bearing platform 11 does not have the function of vacuum adsorption.

Therefore, as shown in FIG. 3, the printed circuit board 2 can be placed on the carrying surface 111 of the carrying platform 11, and then the gas line device 13 performs the pumping action, that is, the air hole 113 of the carrying platform 11 can be used to print the circuit. The plate 2 is adsorbed on the bearing surface 111 of the carrier platform 11. Since the air hole 113 placed in the vent plug 114 has the function of adsorbing, the vent plug 114 can be placed in the selected air hole 113 in accordance with the type of the printed circuit board 2, so that the printed circuit board 2 can be more fully provided. It is adsorbed on the bearing surface 111 of the carrier platform 11 and does not cause a situation in which some of the air holes 113 are not sufficiently in contact with the printed circuit board 2, resulting in air leakage and insufficient adsorption, which greatly enhances the effect of adsorbing the printed circuit board 2.

The present invention selectively sets the vent plug 114 through the air holes 113 on the carrying platform 11, and the air vent 113 provided in the vent plug 114 has the ability to adsorb, and thus can be adjusted according to the type of the printed circuit board 2. The position of the vent plug 114 allows the printed circuit board 2 to be attached to the carrying platform 11 to make the vacuum adsorption platform 1 more capable of adsorbing.
