Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In an embodiment of the centering platform provided by the present invention, please refer to fig. 1 to 3, which includes a supporting base and a plurality of positioning devices. The support base is used for providing Z-direction support for the printing piece 1. The positioning device is used for clamping and positioning the printing piece 1 along a corresponding preset positioning direction perpendicular to the Z direction. Each positioning device corresponds to a preset positioning direction perpendicular to the Z direction as the direction for positioning the printing piece 1, and after the positioning device clamps the printing piece 1, the movement of the printing piece 1 in the preset positioning direction corresponding to the positioning device can be limited.
Wherein at least one positioning device is an adjustable positioning device.

The first fixed positioning part and the adjustable positioning part are arranged on two sides of the supporting seat, and can be driven by the adjustable positioning driving device to approach along the corresponding preset positioning direction so as to clamp and position the printing piece 1.
In practical use, as shown in fig. 2, the X direction, the Y direction and the Z direction are two straight line directions on a horizontal plane, and the Z direction is a straight line direction consistent with the up-down direction.
The number of the positioning devices can be one, two or more than two according to actual needs. When the positioning device is only one, the positioning device is an adjustable positioning device.
The centering platform can be applied to a pad printing machine or other devices or systems needing to position workpieces.
The printing piece 1 is located on the supporting seat between the first fixed positioning part and the adjustable positioning part, in the adjustable positioning device, the adjustable positioning driving device drives the first fixed positioning part and the adjustable positioning part to move close to each other along the corresponding preset positioning direction (such as Y direction), and when the printing piece 1 is clamped, the adjustable positioning part can push the printing piece 1 to be tightly attached to the first fixed positioning part due to the rotatable arrangement of the adjustable positioning part, and meanwhile, the angle of the adjustable positioning part is adjusted, so that the adjustable positioning part is also tightly attached to the printing piece 1.
Therefore, in the preset positioning direction corresponding to the adjustable positioning device, the first fixed positioning part is used as a positioning reference, and the angle of the adjustable positioning part is adaptively adjusted under the action of the printing piece 1 so as to adapt to the direction of the first fixed positioning part, so that the printing piece 1 can be adaptively clamped by the adjustable positioning part and the first fixed positioning part to be positioned, the shaking of the printing piece 1 in the direction is avoided, the positioning reliability is effectively improved, and the accurate centering positioning of the printing piece 1 is facilitated.
Further, the first fixed positioning portion includes a first fixed link 511 fixed to an output portion of the adjustable positioning driving device, and at least two first positioning posts 58 are fixed on the first fixed link 511 at intervals.

If a plate-like structure is directly used for contacting to position one surface of the printing piece 1, when the processing error of the plate-like structure is large or the surface of the printing piece 1 is curved, it is difficult to ensure the contact area between the plate-like structure and the printing piece 1. In this embodiment, at least two positioning columns are used to position one surface of the printed part 1 in a manner of matching, and each positioning column can be in good contact with different positions on the side surface of the printed part 1, so that the positioning effect is ensured, meanwhile, the manufacturing materials of the connecting part are saved, and the processing difficulty is reduced.
The number of the first positioning posts 58 and the second positioning posts 57 may be two, three, five or other numbers as needed. The number of the adjustable links 512 may be the same as or different from the number of the links on the first fixed link 511. In addition, on the same connecting rod, the interval between adjacent reference columns can be set according to actual needs.
Specifically, referring to fig. 3, two second positioning posts 57 are fixedly disposed on the adjustable connecting rod 512 in parallel, and two first positioning posts 58 are fixedly disposed on the first fixed connecting rod 511 in parallel. The two second positioning posts 57 disposed on the adjustable link 512 are preferably disposed at equal intervals from the rotation center of the adjustable link 512. During the process of clamping the printing piece 1, the two first positioning columns 58 and the two second positioning columns 57 can both contact the printing piece 1 through the adaptive swing adjustment of the adjustable connecting rod 512.
Further, a rotation limiting structure 56 for limiting the swing angle range of the adjustable link 512 is provided on the output portion of the adjustable positioning device. By setting the rotation limiting structure 56, the swing of the adjustable link 512 can be limited within a reasonable range, and the adjustable link 512 can be more quickly adjusted to a state of being attached to the printing piece 1 without greatly swinging in the positioning process.

Of course, the number of the third positioning posts 49 in each second fixed positioning portion may be two or other values.
For the rectangular printed matter 1, taking mobile phone glass as an example, on the supporting seat, the length direction of the mobile phone glass is parallel to the X direction, and the width direction is parallel to the Y direction. The fixed positioning device can be used for clamping the side corresponding to the short side for positioning, and because the side length is short, the fixed positioning can be performed reliably by directly passing through the second fixed positioning part which can not rotate around the Z-direction shaft, and further the side corresponding to the long side of the mobile phone glass is clamped and positioned by being matched with the adjustable positioning device, so that the reliable positioning of the whole mobile phone glass can be ensured, and the processing is convenient.
Further, the fixed position of the at least one second fixed positioning portion on the output portion of the fixed positioning driving device is adjustable, for example, adjustable along the Y direction or adjustable along the X direction, so that the relative positions of the two second fixed positioning portions can be adjusted as required, and applicability is improved. After the position of the second fixed positioning part is adjusted on the output part of the fixed positioning driving device, the second fixed positioning part is fixed relative to the output part of the fixed positioning driving device.
