The position of the first stopper 17 is configured so that when the pallet assembly 2 located upstream of the first stopper 17 abuts against the first stopper 17, the pallet assembly 2 located at each station can just reach the predetermined position. The position of the second stopper 18 is configured so that only one pallet assembly 2 can be accommodated between it and the first stopper 17. Each of the lifting mechanisms 13 can only lift one pallet assembly 2 at a time. Through the cooperation of the first stopper 17 and the second stopper 18, only one pallet assembly 2 is allowed to enter the lifting mechanism 13 at a time. The first stopper 17 and the second stopper 18 adopt the existing technology. Similarly, two stoppers are also arranged at the end of the lower conveying mechanism 12.

[0083] The lifting mechanism 13 includes a lifting box 131, a lifting frame 132 movably disposed in the lifting box 131, and a lifting conveyor belt 133. The lifting box 131 is open on one side facing the conveying mechanism. The lifting conveyor belt 133 is disposed on the lifting frame 132. The conveying direction of the lifting conveyor belt 133 is parallel to the first conveying direction. The lifting conveyor belt 133 can receive the pallet assembly conveyed by the conveying mechanism and return the pallet assembly to the conveying mechanism. The lifting of the lifting frame 132 adopts the existing technology.

[0084] The lifting mechanism at the end of the upper conveying mechanism 11 is used to convey the pallet assembly 2 from the upper conveying mechanism 11 to the lower conveying mechanism 12 , and the lifting mechanism at the end of the lower conveying mechanism 12 is used to convey the pallet assembly 2 from the lower conveying mechanism 12 to the upper conveying mechanism 11 .

[0085] The support assembly loading mechanism G2 includes a turntable G22 rotatably arranged on one side of the conveying mechanism 1, eight fixed gauges G22 arranged on the turntable G22, and a magnetic gauge G24 arranged on each fixed gauge G22, and the support assembly 101 can be buckled upside down on the magnetic gauge G24. During operation, the support assembly 101 is manually buckled upside down on the magnetic gauge G24, and the turntable G22 drives the support assembly 101 to rotate to the material taking position, and the eighth material moving mechanism G1 takes it away.

[0086] Preferably, there are two bracket assembly loading mechanisms G2 and two eighth material moving mechanisms G1, and each eighth material moving mechanism G1 removes two bracket assemblies 101 from the corresponding bracket assembly loading mechanism G2 each time.

[0087] Furthermore, the support assembly 101 includes a cover-shaped support 1011 and a U-shaped cup 1012, the opening of the U-shaped cup 1012 faces the support 1011, and the opening of the U-shaped cup 1012 is connected to one end of the cover-shaped support 1011 by glue. In order to make the U-shaped cup 1012 and the cover-shaped support 1011 more tightly fixed, before the support assembly 101 is loaded onto the tray assembly 2, it is necessary to apply another layer of glue at the connection between the U-shaped cup 1012 and the support 1011. For this purpose, a set of fifth glue coating mechanisms G21 is provided on one side of each turntable G21 to apply glue to the two support assemblies 101 at the same time. During the gluing process, the fixing gauge G22 can rotate.
