In practical use, the length of the two side faces 14 perpendicular to the direction away from the end face 11 is determined by the side face length of the glass substrate.
Specifically, the attachment zone 22 is adhesively attached to the side 14.
Referring to fig. 5, in some embodiments, the receiving groove 12 includes a bar-shaped groove, and a length direction of the bar-shaped groove is parallel to an extending direction of an edge of the end face 11 to which the side face 14 is connected.

In practical applications, the length of the grooves is determined by the length of the sides of the glass substrate, the width of the grooves is determined by the width of the glass substrate and the thickness of the cladding layer 20, and the depth of the grooves is determined by the distances between the front and back lines and the sides of the glass substrate.
As shown in fig. 5, alternatively, the jig head includes a plurality of suction holes 13, and the plurality of suction holes 13 are spaced apart from each other along the length direction of the bar-shaped groove.
In this embodiment, the plurality of adsorption holes 13 are spaced apart from each other along the length direction of the strip-shaped groove, so that each part of the deformation zone 21 opposite to the accommodating groove 12 can be adsorbed into the accommodating groove 12 at the same time, and the glass substrate can enter the accommodating groove 12 to contact with the cladding layer 20 conveniently.
As shown in fig. 5, the plurality of adsorption holes 13 are exemplarily uniformly distributed on the bottom of the bar-shaped groove.
The plurality of adsorption holes 13 are uniformly distributed on the bottom of the bar-shaped groove, so that each part of the deformation zone 21 opposite to the accommodating groove 12 can be adsorbed into the accommodating groove 12 at the same time.
In practical applications, the strip-shaped groove is a non-through groove, that is, the end face 11 is provided with blocking structures, such as bosses, on two opposite edges of the strip-shaped groove extending in a direction perpendicular to the length direction, so as to cooperate with the cladding layer 20 to seal the accommodating groove 12. In addition, the orthographic projection of the cladding layer 20 on the end face 11 is connected with the blocking structure but is not overlapped, and deformation of the cladding layer 20 is prevented from being influenced under the condition that the tightness of the accommodating groove 12 is ensured.
Referring to fig. 6, in some embodiments, the coating layer 20 includes a first deformation layer 23, a cord layer 24, and a second deformation layer 25 sequentially stacked in a direction near the end face 11, the second deformation layer 25 having a hardness less than that of the first deformation layer 23.
Wherein the first deformation layer 23 and the second deformation layer 25 are laminated structures made of deformable materials, and the cord layer 24 is a mesh structure layer similar to that in an automobile tire.
In practical application, the steel plate is provided with a plurality of grooves which are distributed at intervals, silver paste is filled in the grooves, and the distance between two adjacent grooves is consistent with the distance between two adjacent side connecting lines. The coating layer 20 is pressed on the steel plate through the jig head 10, and silver paste in the groove is transferred onto the coating layer 20 to form a connecting line layer. And then the glass substrate is contacted with the coating layer 20, and the connecting line layer is transferred onto the glass substrate to form a side connecting line, so that printing is completed. Since the silver paste is located in the grooves of the steel sheet, a certain deformation is required when pressing the clad layer 20 against the steel sheet in order to transfer the silver paste in the grooves to the clad layer 20.
