[0035] It can be seen that the first driving member 20 drives the two first assembling members 21 to approach the bearing platform 4 synchronously, pushes the two first wooden strips 10 to approach each other, and further connects the two ends of each fourth wooden strip 13 to the corresponding first wooden strip 10 and the third wooden strip 12 through the mortise and tenon structure, so as to realize the assembly of the "field"-shaped frame and further improve the applicability of the assembly.

[0036] As an implementation manner, the first driving member 20 includes at least one set of driving parts. Each set of driving parts includes a first motor and a first transmission lead screw. The first transmission lead screw extends along the first direction and is rotatably installed on the frame 1. The fixed end of the first motor is installed on the frame 1, the driving end of the first motor is coaxially connected to one end of the first transmission lead screw. The first thread section and the second thread section are arranged at intervals along the first direction on the first transmission lead screw. The spiral directions of the first thread section and the second thread section are opposite. A first lead screw nut is fixed at the bottom of each of the two first assembling members 21.

The third positioning unit has a "cross"-shaped positioning groove. The positioning groove includes a third positioning groove 7 and a fourth positioning groove 8 that communicate with each other. The third positioning groove 7 corresponds to the two first positioning grooves 50 to limit the two ends of the third wooden strip 12, and the fourth positioning groove 8 corresponds to the two second positioning grooves 60 to limit the two ends of the fourth wooden strip 13. Obviously, by limiting the two ends of the third wooden strip 12 and the fourth wooden strip 13, the assembly accuracy of the third wooden strip 12 and the fourth wooden strip 13 is further improved.

[0044] When the above automatic picture frame assembly device is assembled: First, manually place the two second wooden strips 11 against the two second assembly members 31 respectively, and then place a third wooden strip 12 in the first positioning groove 50. After the placement is completed, the second driving member 30 drives the two second assembly members 31 to approach each other, pushing the two second wooden strips 11 to approach each other, and then connecting the two ends of the third wooden strip 12 to the two second wooden strips 11 through a mortise and tenon structure; Then, manually place the two first wooden strips 10 against the two first assembly members 21 respectively, and then place the two fourth wooden strips 13 in the two second positioning grooves 60 respectively; Finally, the first driving member 20 drives the two first assembly members 21 to approach the bearing platform 4 synchronously, and pushes the two first wooden strips 10 to approach each other through the limiting members 210, and then connects the two ends of each fourth wooden strip 13 to the corresponding first wooden strip 10 and third wooden strip 12 through a mortise and tenon structure.
