While the two clamping cylinders 61 drive the limiting protrusion 63 to clamp and position the material tray 28, the material stop block 65 clamps and positions the material tray 4, which can perform secondary positioning and centering of the material tray 4 to ensure the relative position of the material tray 4 with respect to the positioning pressure plate 5.

[0046] In one embodiment of the present invention, anti-return components 13 are provided on both sides of the receiving frame 12, the anti-return components 13 are provided on the anti-return frame 121, and an anti-return device 122 is provided on the anti-return frame 121, the anti-return device 122 is located above the transmission gap 113.

Support baffles 143112 are disposed on both sides of the support plate 142, and the support plate 142 is located above the transmission gap 113.

[0049] Specifically, the support plate 142 is located above the transmission gap 113, which can avoid affecting the material tray 4 in picking up and putting down materials and avoid interference. The lifting module 23 drives the lifting plate 24 and the receiving tray 28 on it to rise, and after lifting the stacked material tray 4 on the support plate 142, the support cylinder 141 drives the support plate 142 to retract. While the lifting module 23 drives the stacked material tray 4 to descend, the support cylinder 141 drives the support plate 142 to pass between the first and second material trays 4 located from bottom to top of the stacked material trays 4, separating the two material trays 4, making the material trays 4 easier to separate and reducing damage to the material trays 4.

[0050] Usage process

[0051] The stacking tray 4 is placed inside the loading frame 11 on the loading drawer 1. The baffles 111 and 112 surround the loading drawer 1, positioning the four corners of the stacking tray 4. Then, the loading drawer 1 is pushed to the loading rack 15. The support cylinder 141 drives the support plate 142 to pass through the loading station, supporting the bottom of the stacking tray 4. The linear module 21 drives the lifting module 23 on the feeding rack 22 to move to the lowest point of the loading station. The lifting module 23 then drives the lifting... As the lowering plate 24 and its receiving tray 28 rise, lifting the stacked trays 4 on the support plate 142, the support cylinder 141 drives the support plate 142 to retract. Simultaneously, the lifting module 23 lowers the stacked trays 4, while the support cylinder 141 drives the support plate 142 to pass between the first and second trays 4 located from bottom to top, separating the two trays 4. The lifting module 23 then moves the separated trays 4 onto the transfer gap 113, and the linear module 21... The material tray 4 moves through the transmission gap 113 to below the positioning plate 5. The lifting module 23 drives the receiving tray 28 and the material tray 4 to move upward, so that the material tray 4 abuts against the positioning plate 5, and compresses the springs 56 at the four corners of the positioning plate 5. After reaching a suitable height, the two clamping cylinders 61 drive the limiting protrusions 63 on the clamping plates 62 on both sides to clamp and position the material tray 28 on both sides. While positioning, the stop block 65 clamps and positions the material tray 4 to ensure the positional accuracy of the material tray 4. After the material tray 4 is loaded, it moves to the position plate 5. The linear module 21 drives the empty material tray 4 to move to the receiving frame 12 through the transmission gap 113. The lifting module 23 drives the empty material tray 4 to be lifted and stacked one by one through the check valves 122 on both sides. The material tray 4 has the advantages of high loading and unloading efficiency, ease of use, and high stability during loading and unloading.
