[0029] Refer to Figure 1, A screen printing machine, comprising: a machine table 100, a feeding mechanism 500, and a turning plate mechanism 300. The machine table 100 is provided with a material transportation area; the feeding mechanism 500 is arranged on the machine table 100, and the feeding mechanism 500 is used to drive the material to displace relative to the machine table 100; wherein, the feeding mechanism 500 includes a material taking component 580, and the material taking component 580 is used to obtain the material and enable it to displace within the material transportation area; the material taking component 580 is movably arranged below the material transportation area. The turning plate mechanism 300 is arranged on the machine table 100, and the turning plate mechanism 300 can move closer to or away from the material transportation area. The turning plate mechanism 300 is located on the side and / or above the material transportation area, and the turning plate mechanism 300 is used to drive the material to flip relative to the machine table 100. After the turning plate mechanism 300 obtains the material, it can drive the material to flip relative to the machine table 100, thereby directly and effectively completing the turning plate action in the screen printing operation. After the turning plate operation is completed, the material taking component 580 can obtain the material. After obtaining it, the feeding mechanism 500 can drive the material to move away from the material transportation area through the material taking component 580, so that the material can leave the material transportation area after the turning plate action, facilitating the next processing operation of the material. Since the material taking component 580 moves and obtains the material below the material transportation area, and the turning plate mechanism 300 performs the turning plate action on the side or above the material transportation area, the working positions of the feeding displacement component and the turning plate component can be effectively divided into different positions of the material transportation area, thus ensuring that it is difficult for interference to occur between the two, and enabling the spaces in different positions to be effectively utilized, which is conducive to the screen printing operation.

[0030] Specifically, the feeding mechanism 500 is arranged below the material transportation area, and the turning plate mechanism 300 is arranged above the material transportation area. By setting them separately in the up and down directions, the feeding mechanism 500 and the turning plate mechanism 300 can be as far away as possible, effectively avoiding the problem of mutual interference when they move relative to each other, and making the most of the space on the machine table 100 as much as possible, thus achieving the purpose of saving space.

[0031] In some embodiments, referring to Figure 2, the feeding mechanism 500 includes a guide rail assembly 550 and a driving assembly 510. The guide rail assembly 550 is located below the material transportation area; the material picking assembly 580 is movably connected to the guide rail assembly 550; the driving assembly 510 is connected to the guide rail assembly 550 and can drive it to reciprocate relative to the material transportation area. When it is necessary to drive the material into or out of the material transportation area, the driving assembly 510 can be started, and it drives the guide rail assembly 550 to move closer to the material. After that, the material picking assembly 580 on the guide rail assembly 550 can obtain the material and drive the material to displace under the action of the driving assembly 510. After the material moves to the material transportation area, the material picking assembly 580 can move relative to the linear track, so as to adjust the position between the material and the material transportation area, and further ensure that the flap mechanism 300 can smoothly obtain the material and drive it to flip.

[0032] Specifically, there are two material picking assemblies 580, and both are slidably connected to the guide rail assembly 550. The guide rail assembly 550 includes a linear guide rail, a mounting seat, and a lead screw pair 530. The linear guide rail is installed on the machine table 100 through the mounting seat, and both material picking assemblies 580 are slidably installed on the linear guide rail; both material picking assemblies 580 are connected to the lead screw pair 530, and when the lead screw pair rotates, it can drive the two material picking assemblies 580 to move synchronously and in opposite directions.

[0033] Furthermore, the lead screw pair includes a motor and a lead screw, and the motor is used to drive the lead screw to rotate. The two material picking assemblies 580 are respectively threadedly connected to both ends of the lead screw pair, and the spiral directions of the two material picking assemblies 580 are opposite.

[0034] In some embodiments, referring to Figure 4 , the driving assembly 510 includes a servo motor 513, a synchronous belt 517, and a synchronous pulley 515. The servo motor 513 is connected to the synchronous belt 517 through the synchronous pulley 515 and can drive it to move, and the guide rail assembly 550 is installed on the synchronous belt 517 and can move along with it. After the servo motor 513 is started, it will drive the synchronous belt 517 to move through the synchronous pulley 515. Thus, the guide rail assembly 550 connected to the synchronous belt 517 can move along with the synchronous belt 517, and drive the material to displace through the material picking assembly 580, so as to facilitate the feeding operation of the material.

[0035] It can be envisioned that it can also be directly connected to the guide rail assembly 550 by components such as cylinders and hydraulic cylinders and drive it to move. Therefore, the specific implementation method is not unique, but can be adjusted according to the actual situation and is not limited here.

[0036] In some embodiments, referring to Figure 5, the material taking assembly 580 includes a lifting cylinder 590 installed on the guide rail assembly 550. The driving assembly 510 is connected to the lifting cylinder 590 and can drive it to reciprocate along the guide rail assembly 550. The lifting cylinder 590 is connected to a finger cylinder 570 and can drive it to rise close to the material conveying area or descend away from the material conveying area. The lifting cylinder 590 can drive the finger cylinder 570 to rise or fall, so that the finger cylinder 570 located below the material conveying area can smoothly move into the material conveying area and clamp the material. Therefore, the effect of taking the material from below the material can be effectively achieved.

[0037] In some embodiments, referring to Figure 2 , the flap mechanism 300 includes a flipping assembly 330 and a pallet assembly 370. The pallet assembly 370 is located in the material conveying area and can support the material. The flipping assembly 330 can move close to the pallet assembly 370 and drive the material on the pallet assembly 370 to flip. After the feeding mechanism 500 drives the material into the material conveying area, it will place the material on the pallet assembly 370, so that the pallet assembly 370 can transfer and position the material waiting to be flipped. Then, the flipping assembly 330 can move close to the pallet assembly 370, obtain and flip the material on the pallet assembly 370, so that the flap operation can be effectively completed.

[0038] It can be anticipated that the feeding mechanism 500 can also be directly docked with the flipping assembly. Therefore, the specific implementation method is not unique, but can be adjusted according to the actual situation and is not limited here.

[0039] In some embodiments, referring to Figure 2 , the flipping assembly 330 includes a lifting driver 331, a flipping driver 332, and a flap gripper 335. The flipping driver 332 is located above the pallet assembly 370 and can move close to or away from the pallet assembly 370 under the drive of the lifting driver 331. The flipping driver 332 can drive the flap gripper 335 to rotate relative to the pallet assembly 370. The lifting driver 331 drives the flap gripper 335 to perform a lifting motion, while the flipping driver 332 drives the flap gripper 335 to perform a flipping motion. Therefore, after the flipping gripper moves close to the material under the drive of the lifting driver 331, it can clamp the material, and then drive the material to perform a flipping operation under the action of the flipping driver 332, thereby achieving the flipping effect of the material.

[0040] Specifically, the lifting drive 331 includes a motor and a belt. The motor is connected to the flipping drive 332 through the belt and drives it to lift. The flipping drive 332 is composed of a motor and a connecting frame. The flipping jaws are installed at the end of the connecting frame. When the motor drives the connecting frame to rotate, the effect of flipping the material can be achieved. Of course, the specific implementation method is not unique and can be adjusted according to the actual situation, which is not limited here.

[0041] Further, a plurality of flipping jaws are provided on the connecting frame.

[0042] In some embodiments, referring to Figure 3 , the pallet assembly 370 includes at least two pallet frames 371 movably connected to the machine table 100. A part of the pallet frame 371 extends into the material transportation area and is provided with a guiding portion 375. At least two pallet frames 371 can move relative to each other and approach or move away from each other. The pallet frame 371 is used to support the material, and under the action of the guiding portion 375, the material can be stably placed at the middle position between the two pallet frames 371, so as to smoothly achieve the effect of transferring and positioning the material.

[0043] Specifically, the guiding portion 375 includes an inclined surface that slopes downward toward the center of the material transportation area, and the material is guided to the middle of the material transportation area by the influence of the inclined surface and the self-weight of the material.

[0044] In some embodiments, referring to Figure 6 , the machine table 100 is provided with an alignment mechanism 800. The alignment mechanism 800 is docked with the pallet assembly 370. The alignment mechanism 800 is used to support the material and adjust the position and / or orientation of the material relative to the material transportation area. The alignment mechanism 800 can align and guide the material in the pre-treatment to the pallet frame 371, so that the transition movement of the material between the inside and outside of the material area can be effectively carried out, and problems such as misalignment, collision, and damage of the material when entering the material transportation area can be avoided.

[0045] In some embodiments, referring to Figure 6 , the alignment mechanism 800 includes an alignment platform 810. A first wheel frame 851 and a second wheel frame 852 are provided on the alignment platform 810. A plurality of guide wheels 860 are provided on both the first wheel frame 851 and the second wheel frame 852. The first wheel frame 851 and the second wheel frame 852 can move closer to or away from each other. The first wheel frame 851 and the second wheel frame 852 move relative to the alignment platform 810 respectively. After the two respectively correspond to a pallet frame 371, the material can smoothly and accurately move onto the pallet frame 371 through the guide wheels 860, and the effect of transferring and positioning the material can be achieved through the pallet frame 371, thereby avoiding mistakes in the process of the material moving into the material transportation area.

[0046] In some embodiments, referring toFigure 6 Specifically, the pallet assembly 370 includes two pallet racks 371 connected to the machine table 100. The first wheel rack 851 and the second wheel rack 852 are respectively docked with the two pallet racks 371. The alignment platform 810 is provided with an adjusting screw rod 870. Both the first wheel rack 851 and the second wheel rack 852 are connected to the adjusting screw rod 870, and the adjusting screw rod 870 is used to adjust the relative distance between the first wheel rack 851 and the second wheel rack 852. Under the action of the adjusting screw rod 870, the first wheel rack 851 and the second wheel rack 852 can be displaced relative to the machine table 100, so as to adjust the relative distance between the first wheel rack 851 and the second wheel rack 852, and further ensure that the first wheel rack 851 and the second wheel rack 852 can be smoothly and accurately docked with the pallet rack 371, so that the material can smoothly move from the first wheel rack 851 and the second wheel rack 852 to the pallet rack 371.

[0047] Specifically, a motor 840 is provided on the alignment platform 810. The motor 840 is connected to the adjusting screw rod 870 and can drive it to rotate.
