[0033] When the top plate 110 moves downward a set distance, the bottom of the material tray 400 on the support plate 130 is connected to the conveying structure, and the material tray 400 is transferred from one rack 100 to another rack 100 through the conveying structure.

[0034] The above-mentioned filling machine material tray 400 reflux mechanism first lifts the material tray 400 through the top plate 110 on the first frame 100, so that the material tray 400 enters the processing line above the filling machine material tray 400 reflux mechanism, and the material tray 400 is used to place the electric core. After the processing is completed, the material tray 400 comes to the top of the second frame 100, and the second frame 100 lifts the top plate 110 so that the supporting surface abuts against the bottom of the material tray 400. After stably lifting the material tray 400, the top plate 110 moves downward a certain distance, so that the material tray 400 is in contact and connected with the conveying structure, and the material tray 400 is conveyed back to the first frame 100 through the conveying structure, so as to realize the reflux of the material tray 400 and improve the work efficiency.

[0035] A fixed cylinder 140 is provided below the top plate 110, the bottom of the cylinder 140 is fixedly connected to the bottom of the frame 100, the top of the cylinder 140 is provided with a piston rod that can move up and down, and the top of the piston rod is connected to the bottom of the top plate 110. In this way, the top plate 110 can be lifted or lowered by the cylinder 140, so that the top plate 110 can be moved conveniently.

[0036] The conveying structure includes two conveying chains 200 arranged in parallel. The conveying chains 200 are arranged to extend along the length direction of the conveying area. The ends of the conveying chains 200 extend above the top plate 110 to form end sections. The end sections are located between two support plates 130. The height of the support plates 130 is higher than that of the end sections. A driving motor 210 for driving the conveying chain 200 to move is connected to one end section.

[0037] When the top plate 110 moves downward by a set distance, the bottom of the material tray 400 on the support plate 130 presses against the conveyor chain 200, and the driving motor 210 drives the conveyor chain 200 to move, and the material tray 400 is transferred from one frame 100 to another frame 100 through the conveyor chain 200. In this way, the friction between the conveyor chain 200 and the material tray 400 realizes the conveying and reflux of the material tray 400.

[0038] Specifically, the support plate 130 is arranged horizontally. In this way, the liquid injection machine tray is moved by the power of the conveyor chain 200 to ensure that the tray is placed stably.

In this way, the design of the ball bearings 410 can prevent the tray 400 from being severely rubbed and a large amount of dust from accumulating at the bottom during transportation.

[0043] The support surface is provided with a boss-shaped support platform 131 that protrudes upward; when the top plate 110 moves downward by a set distance, the top of the support platform 131 abuts against the bottom of the material tray 400, and a plurality of balls 410 press against the support surface. In this way, the material tray 400 is prevented from being placed unsteadily on the support surface.
