If there is a deviation, the alignment mechanism 370 can move the stage 380 along the first direction D1 and/or the second direction D2, or even rotate the stage 380 along the rotation axis RX, so that the display panel 200 on the stage 380 moves to Ideal location.

After the alignment is completed, the glue dispenser 340 is moved to above the connecting member 150 that overlaps the display panel 200 , as shown in FIG. 6C . After reaching the position, the dispenser 340 descends to a position close to the connecting member 150, and injects the adhesive material 190M into the hole 150h of the connecting member 150. It is particularly important to note that the adhesive material 190M will contact part of the surface of the display panel 200 within the hole 150h and the side wall of the connector 150 that defines the hole 150h, and solidify to form an integrated adhesive layer 190, as shown in FIG. 6D.

In this embodiment, the automatic splicing equipment 300 may further include a curing element 350, which is movably disposed on the first moving mechanism 310 and is suitable for curing the adhesive layer 190. For example, after the step of injecting the adhesive material 190M (as shown in FIG. 6C ) is completed, the curing element 350 is moved to above the connecting member 150 with the adhesive material 190M injected into the hole 150h. After the curing element 350 reaches the position, it descends to a position close to the connector 150 and irradiates the adhesive material 190M in the hole 150h with ultraviolet light to solidify the adhesive material 190M into the adhesive layer 190 . That is, the curing element 350 of this embodiment may be an ultraviolet light source, but is not limited thereto.

The connection relationship between other connectors 150 and the display panel 200 can be achieved by repeating the steps shown in FIG. 6C and FIG. 6D , and will not be described again here. After the display panel 200 is connected to all corresponding connectors 150 , a splicing step of the display panel 200 on the frame member 100 is completed. By repeating the steps of FIG. 6A to FIG. 6D , multiple display panels 200 can be spliced and fixed on the frame member 100 , and the splicing display device 10 of FIG. 2 is completed.

In particular, since the display panel 200 and the connector 150 are connected through glue dispensing, the production efficiency and efficiency of the spliced display device 10 can be increased. Heavy duty convenience.
