[0024] The following combines specific embodiments to further elaborate on the content of the present utility model:

[0025] In the description of the utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the utility model.

[0026] As Figure 1 、 Figure 4 shown, a loading device for a loading trolley, on which multiple material trays 21 filled with materials can be vertically stacked, includes: a lifting drive mechanism for driving the overall rise of the material trays 21 on the loading trolley, including a load platform and a driving member for driving the load platform to lift; a guiding mechanism for guiding the loading trolley to the operation station where the lifting drive mechanism is located and guiding the overall rise of the material trays 21; a limiting mechanism for limiting the loading trolley at the operation station of the lifting drive mechanism to prevent the loading trolley from moving.

[0027] As Figure 1 、 Figure 2As shown in the figure, the guiding mechanism includes a first horizontal plate 1 and a second horizontal plate 2 which are fixedly arranged in parallel with a spacing matching the width of the feeding trolley, and a first vertical plate 3 and a second vertical plate 4 which are fixedly arranged in parallel with a spacing matching the width of the material tray 21. The cross-sections of the first vertical plate 3 and the second vertical plate 4 are L-shaped, as Figure 4 shown, the feeding trolley is also provided with a third vertical plate 5 and a fourth vertical plate 6 with L-shaped cross-sections, which cooperate with the first vertical plate 3 and the second vertical plate 4 to guide the rising of the material tray 21; both ends of the first vertical plate 3 and the second vertical plate 4 in the longitudinal direction extend with first guide plates 7 inclined outwardly therefrom. The setting of the first guide plates 7 facilitates the lifting and lowering of the loading platform, that is, it ensures that the first vertical plate 3 and the second vertical plate 4 guide the lifting and lowering of the material tray 21 and at the same time avoids the interference caused by the first vertical plate 3 and the second vertical plate 4 to the lifting and lowering of the loading platform; the parts of the first vertical plate 3 and the second vertical plate 4 parallel to the moving direction of the feeding trolley into the working station of the lifting drive mechanism are the first side plates 8 and the second side plates 9 respectively. The free ends of the first side plates 8 and the second side plates 9 in the width direction extend with second guide plates 10 inclined outwardly therefrom. The setting of the second guide plates 10 ensures that the material tray 21 of the feeding trolley smoothly enters the first vertical plate 3 and the second vertical plate 4. The first horizontal plate 1 and the second horizontal plate 2 together form a feeding channel at the working station where the feeding trolley enters the lifting drive mechanism. At the same time, it limits the width direction of the feeding trolley; one end of the first horizontal plate 1 and the second horizontal plate 2 located at the entrance of the feeding channel extends with a third guide plate 11 inclined outwardly. The setting of the third guide plate 11 ensures that the feeding trolley smoothly enters the feeding channel.

[0028] As Figure 3 shown, there are a pair of limiting mechanisms, which are respectively located on both sides of the lifting drive mechanism; each limiting mechanism includes a first pull plate 12 and a driving member for driving the first pull plate 12 to rotate in the vertical plane. In this embodiment, the driving member for driving the first pull plate 12 to rotate in the vertical plane is a rotary cylinder 13; a buffer pad 14 is installed on the end surface of the first pull plate 12 facing away from the feeding trolley; a detecting member for detecting the position of the feeding trolley is installed on the side of each limiting mechanism. In this embodiment, the detecting member for detecting the position of the feeding trolley is a proximity switch 15. As Figure 4 shown, the feeding trolley is provided with a second pull plate 16 which cooperates with the limiting mechanism. When the proximity switch 15 detects that the feeding trolley is pushed to the predetermined position, the rotary cylinder 13 drives the first pull plate 12 to rotate, so that the first pull plate 12 and the second pull plate 16 interactively hold each other, and at the same time the buffer pad 14 is located between the first pull plate 12 and the second pull plate 16, so as to fix the feeding trolley in the length direction along the first horizontal plate 1 and the second horizontal plate 2.

[0029] As Figure 1 、 Figure 2As shown in the figure, the driving member for driving the lifting of the stage is an electric cylinder 17. The stage includes an adapter plate 18 vertically fixed on the movable part of the electric cylinder 17 and a fixing plate 19 horizontally fixed on the adapter plate 18. A process hole is formed in the fixing plate 19, and a detecting member for detecting whether there is a material tray 21 on the fixing plate 19 is arranged below the fixing plate 19. The detecting member for detecting whether there is a material tray 21 on the fixing plate 19 is a photoelectric sensor 20. The fixing plate 19 is slidably matched with the electric cylinder 17 through a pair of linear guide rails. The pair of linear guide rails includes a guide rail fixed on the cylinder body of the electric cylinder 17 and a slider slidably matched with the guide rail and fixed on the fixing plate 19. The linear guide rails ensure the rising precision of the material tray 21.

[0030] The working principle of the feeding device for the feeding trolley in the present utility model is as follows: In the initial state, the stage is located at the lowest end of its stroke, and the first pull plates 12 are all vertically upward. The feeding trolley filled with materials is pushed into the feeding channel jointly formed by the first horizontal plate 1 and the second horizontal plate 2. When the proximity switch 15 detects that the feeding trolley is pushed to the predetermined position, the two limiting mechanisms act, and the first pull plates 12 pull the second pull plates 16, and the feeding trolley is fixed. The electric cylinder 17 of the lifting driving mechanism drives the stage to rise, and the stage lifts all the material trays 21 on the feeding trolley integrally. When it rises to the predetermined position, the stage stops rising. The gripping mechanism (not shown in the figure) takes away the topmost material tray 21, and then the stage continues to lift all the material trays 21 integrally to the predetermined position and then stops rising. The gripping mechanism continues to take away the topmost material tray 21, and the feeding is carried out in this way in sequence. When the last material tray 21 is taken away by the gripping mechanism, the photoelectric switch detects that there is no material tray 21 on the feeding trolley, the two limiting mechanisms release the second pull plates 16, push away the empty feeding trolley, and the stage returns to the lowest end of its stroke, returning to the initial state, and the feeding is cycled in this way.
