Beneficial effects of the present invention: the material sheet blown by the air blowing group is clamped by the clamping sheet group, and the table surface group a located at the starting point is lifted by the servo motor lifting component to pick up the material sheet, and then the group is driven by the linear motor. The tabletop group a moves to the printing position as a whole, and the printing position is located in the middle of the film feeding and conveying group and the film outputting transfer group. The motor drives the tabletop group b to move to the position of the clip group as a whole. During the movement, it passes through the bottom of tabletop group a. After tabletop group b catches the material, it moves to the printing position. Compared with the original turntable structure, the linear motor is used to provide the transmission power. While improving the speed and simplifying the algorithm, the printing accuracy is also improved to a certain extent, and the CT can be reduced by more than 10%. Simplify and effectively improve equipment maintainability.

Detailed ways

The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in Figure 1, an up and down alternate screen printing mechanism includes a mounting frame, a blowing group 1, a clip group 2, a table group a3, a table group b4, a film feeding and conveying group 5, and a film output conveying group 6 and Lifting group 7, one end of the mounting frame is installed with a film feeding and conveying group 5, and the other end of the mounting frame is installed with a filming and conveying group 6. The air blowing group 1 is installed on one side of the film group 2, and the lifting group 7 is installed on the front and back of the mounting frame, and the lifting group 7 includes a linear motor, a servo motor lifting component and a fixing frame. The linear motor is installed on the side of the mounting frame, and the linear motor A servo motor lifting assembly is installed on the upper part, and a fixed frame is installed at the output end of the servo motor lifting assembly. The starting point of one group of lifting groups 7 is the feeding end of the feeding and conveying group 5, and the starting point of the other group of lifting groups 7 is the filming and conveying group. 6 In the feeding end, the table top group a3 is set on the fixed frame whose starting point is the feeding end of the sheet feeding and conveying group 5, and the table group b4 is set on the fixed frame which is located at the starting point at the feeding end of the sheet feeding and conveying group 6.

The working principle of the present invention: the material after blowing by the blowing group 1 is clamped by the clamping group 2, and the table group a3 located at the starting point is lifted by this group of servo motor lifting components to pick up the material, and then the group is connected by a straight line. The motor drives the tabletop group a3 to move to the printing position as a whole, and the printing position is located in the middle of the film feed transmission group 5 and the film output transfer group 6. At the same time, the table table group b4 located at the starting point is slowly lifted by this group of servo motor lifting components, and at the same time The tabletop group b4 is driven by this group of linear motors to move to the position of the clip group 2 as a whole. During the movement, it passes through the bottom of the tabletop group a3. After the tabletop group b4 catches the material, it moves to the printing position, while the tabletop group a3 moves to the film output. The conveying group 6 descends and unloads the material. This process is cycled in sequence. Compared with the original rotary table structure, the linear motor is used to provide the conveying power. While improving the speed and simplifying the algorithm, the printing accuracy is also improved to a certain extent, and the CT can be reduced by more than 10%. , The mechanism is simplified compared with the original equipment, which effectively improves the maintainability of the equipment.
