[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. During the screen printing process, ink on the bottom of the aluminum sheet can cause the screen to stick, affecting the quality of the screen printing. Therefore, it is necessary to frequently break the vacuum (1-2 hours / time) to wipe the bottom of the screen. However, after the vacuum chamber of the vacuum screen printing machine is separated by the first isolation plate 31 and the second isolation plate 32, the left and right sides of the vacuum screen printing machine have a relatively independent workstation. When the bottom of the screen needs to be wiped on one side, only the vacuum of this side chamber needs to be broken, and the vacuum of the other side chamber does not need to be broken, thus saving time and improving efficiency.

[0033] 2. The energy consumption for creating and maintaining a vacuum is different. Creating a vacuum consumes more energy (the energy consumption is high when creating a vacuum from atmospheric pressure, and low energy consumption when maintaining the vacuum after reaching the required level). By breaking the vacuum on one side and not breaking it on the other side, energy saving can be achieved.

[0034] 3. If the vacuum chambers are not separated, since the screen printing frame lifting components are shared, the screen printing frame component must be raised after the hole plugging on one side is completed before the slide on the other side can enter. However, when the vacuum chambers are separated, the screen printing components on the left and right are completely independent. When using alternating mode control, the entry and exit of the left and right slides are unrestricted. For example, the hole plugging speed of the board made on the left is fast, while the hole plugging speed of the board made on the right is slow. After the left side is completed, it can come out immediately. After taking out and putting down the board, it can immediately enter the vacuum chamber for hole plugging, without being affected by the working status of the right side, which can meet different board making needs.

[0035] 4. The front and back sides of the circuit board may have different vacuum requirements, or different circuit boards may have different vacuum requirements. If the vacuum is not separated, the dual-station vacuum screen printing machine cannot meet the above work requirements. However, after separating the vacuum chamber into two vacuum chambers, the two vacuum chambers are independent of each other, and the vacuum degree of each vacuum chamber can be adjusted separately to meet different board production requirements.

[0036] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several deformations and improvements can be made, which belong to the protection range of the utility model.
