[0030] Please refer to Figure 1-2 , the present invention provides a technical solution: an adjustable positioning device for a vacuum adsorption assembly, including:

[0031] An adsorption column 1, with a placing groove 11 provided at its bottom, and a threaded groove 12 extending from the bottom of the placing groove 11;

[0032] An interface 2, which communicates with the vacuum channel 3 inside the adsorption column 1, and the vacuum channel 3 extends upward along the adsorption column 1 and is provided with a plurality of suction ports 4;

[0033] A positioning seat 5, including a base 51 inserted into the placing groove 11 and a pad 52 clamped into the through hole 511 axially penetrating through the base 51;

[0034] A magnet 6, which is filled in the through hole 511, and the pad 52 abuts and positions the magnet 6. A plurality of the adsorption columns 1 are magnetically adsorbed and positioned on the positioning platform of the printing machine through the magnet 6;

[0036] A number of first branch channels radiate from the bottom of the vacuum channel 3, and second branch channels extend upward on the first branch channels, and the second branch channels are docked with the suction ports 4. The above design enables the suction ports 4 to be radially distributed at the top of the adsorption column 1, ensuring stable adsorption and positioning of the object to be printed.

[0037] The base 51 includes a middle part and an inner insertion tube inserted into the placement groove 11. A clamping groove 513 is provided on the inner wall of the inner insertion tube, and the clamping groove 513 is clamped with a clamping block 521 on the side of the backing plate 52. The bottom surface of the clamping block 521 is a wedge surface, which improves the clamping strength between the base 51 and the backing plate 52 and facilitates the pressing-in installation of the backing plate 52.

[0038] A positioning ring 512 extends inside the inner insertion tube, and the positioning ring 512 supports the bottom of the magnet 6, reducing the structural blockage to the magnet and the influence on its magnetic field, and ensuring sufficient magnetic adsorption and positioning effect.

[0039] An outer sleeve 514 with an L-shaped longitudinal section extends outside the inner insertion tube, and the outer sleeve 514 is sleeved on the bottom of the adsorption column 1, improving the positioning strength between the positioning seat 5 and the adsorption column 1.

[0040] The mounting hole 522 is a smooth through hole with a cross-sectional dimension larger than that of the screw 7, or an internal thread hole corresponding to the screw 7, further improving the positioning strength between the positioning seat 5 and the adsorption column 1 and avoiding structural loosening.

[0041] The positioning and assembly process of an adjustable positioning device for a vacuum adsorption assembly in this embodiment includes: pressing the magnet 6 into the through hole 511 of the base 51 from top to bottom and abutting and positioning it with the positioning ring 512, pressing the backing plate 52 into the through hole 511 in the same direction, and positioning it through the clamping block 521 and the clamping groove 513 of the base 51; pressing the above structure into the placement groove 11 upward, and making the outer sleeve 514 sleeved on the bottom of the adsorption column 1, and the screw 7 passes through the annular magnet 6 and is positioned with the mounting hole 522 and the threaded groove 12 of the backing plate 52 to complete the assembly of the adsorption column 1. When in printing use, the adsorption column 1 is magnetically adsorbed and positioned on the magnetic adsorption dots of the positioning platform of the printing machine through the magnet 6, and then the interface 2 can be docked with an external negative pressure system, so that negative pressure is formed in the vacuum channel 3 and the suction ports 4, and the object to be printed is adsorbed and positioned, and the printing process is carried out.
