Detailed Implementation

[0023] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] See Figure 1 , Figure 2 as well as Figure 3 This utility model discloses an automatic feeding device, including a frame 10 and a lifting assembly. A feeding station is provided on the frame 10, and a first limiting member 11 is provided at the feeding station. Specifically, the lifting assembly includes a second limiting member, a lifting plate 20, and a lifting plate drive member 30. The lifting plate drive member 30 can drive the lifting plate along the height direction on the frame 10, and the lifting plate 20 moves closer to or away from the feeding station when moving in the height direction. After the lifting plate 20 moves closer to the feeding station, the second limiting member can abut against the first limiting member 11 to indicate that the lifting plate 20 has moved to the feeding station.

[0027] Based on the above structure, when using the automatic feeding device of this utility model, multiple workpiece trays can be stacked on the lifting plate 20, and the second limiting member can be set on the workpiece tray. After the workpiece trays are stacked, each workpiece tray has a second limiting member that limits and abuts against the first limiting member 11 of the feeding station. In this way, when feeding the workpiece, the workpiece can be placed on the workpiece tray, and then multiple workpiece trays with workpieces are stacked on the lifting plate 20.

[0028] Under the action of the lifting plate drive 30, the lifting plate 20 can move upward, driving the workpiece tray on the lifting plate 20 to be lifted upward. The second limiting member on the uppermost workpiece tray can abut against the first limiting member 11 at the loading station position, thus indicating that the uppermost workpiece tray has moved to the loading position. At this time, the lifting plate drive 30 can stop, and the loading robot can grab the workpiece on the workpiece tray at this position for transfer loading.

[0029] After the workpieces on the top workpiece tray are loaded, the empty workpiece tray can be transferred for unloading. At this time, the lifting plate drive 30 drives the lifting plate 20 to move upward one station. Then, the second limiting member of the top workpiece tray can abut against the first limiting member 11 of the loading station again, and the above loading action can be repeated.

[0030] In other words, in this application, each workpiece pallet is limited and abutted against by its own second limiting member and the first limiting member 11 of the loading station, indicating that the workpiece pallet has moved into place. The loading robot can then promptly grab the workpiece on the workpiece pallet for loading. That is, the second limiting member is set on the workpiece pallet and then cooperates with the first limiting member 11 of the loading station to indicate that the workpiece pallet has been lifted into place. The robot can then accurately grab the workpiece at the loading station position, improving loading efficiency.

[0031] Furthermore, a positioning rod 12 can be installed on the frame 10, and the positioning rod 12 extends along the height direction of the frame 10; the first limiting member 11 is set at the top of the positioning rod 12, so that the first limiting member 11 can be installed on the mounting base of the positioning rod 12, or installed as a separate rod structure. When the workpiece pallet is lifted, the positioning rod 12 used as the mounting base will not interfere with the movement of the lifting plate 20. The workpiece pallet can move into place and abut against the first limiting member 11, so that the positioning is accurate.

[0032] More specifically, in this embodiment, the limiting plate is also equipped with a limiting sensor. The limiting sensor can be set at the bottom of the limiting plate. When the lifting plate 20 moves upward, the uppermost workpiece tray can be lifted upward by the lifting plate 20 and touch the limiting sensor at the bottom of the limiting plate. After the limiting sensor is touched by the second limiting component on the workpiece tray, it can send a limiting signal to indicate that the workpiece tray has moved into place.

[0033] Of course, the limit sensor of the first limiting member 11 can be a photoelectric switch as in the prior art, while the second limiting member can be a limiting piece set on the workpiece tray, with the limiting piece extending into the optical path of the photoelectric switch to achieve limit detection. In addition, the limit sensor can also be a spring-loaded touch switch as in the prior art, so that the edge of the workpiece tray can directly touch the spring-loaded touch switch during lifting to achieve limit.

[0034] Furthermore, the frame 10 is also provided with a support base 14, and a mounting cavity 141 is provided in the support base 14, in which the lifting plate drive component 30 is installed. A guide seat 21 is provided on the lifting plate 20, which extends into the mounting cavity 141 and is connected to the power output end of the lifting plate drive component 30; the guide seat 21 is slidably engaged with the side wall of the mounting cavity 141.

[0035] Based on this structure, the lifting plate drive component 30 can be installed inside the support base 14 of the frame 10, reducing the risk of damage caused by the exposed lifting plate drive component 30. Furthermore, the lifting plate 20 is fitted with a guide seat 21 that extends into the mounting cavity 141 within the support base 14; that is, the drive connection position is located within the mounting cavity 141, and it can also slide within the mounting cavity 141, thus making the drive structure of the lifting plate 20 more stable.

[0036] Furthermore, a guide rod 142 can be provided in the mounting cavity 141, and a guide hole is provided on the guide seat 21 accordingly. The guide rod 142 slides through the guide hole. That is to say, in addition to being guided and limited to the left and right by the side wall of the mounting cavity 141, the lifting movement of the lifting plate 20 can also be guided up and down by the guide rod 142 and the guide hole of the guide seat 21, so that the lifting process is more stable.

[0037] Furthermore, a limiting baffle 22 is provided on the side edge of the lifting plate 20 near the mounting cavity 141. The limiting baffle 22 can abut against the edge of the bottommost workpiece pallet when the workpiece pallets are stacked, thus preventing the workpiece pallets from shifting into the mounting cavity 141 and interfering with the lifting.

[0038] Furthermore, the lifting plate 20 is provided with clearance notches on both sides, which slide in conjunction with the opening sidewall of the mounting cavity 141. The clearance notches can avoid the sidewall of the opening position of the support base 14, reducing movement interference.

[0039] Furthermore, a positioning post 13 is provided on the frame 10. Specifically, a positioning through hole 23 can be provided on the lifting plate 20. The positioning post 13 passes through the positioning through hole 23 to the top of the lifting plate 20, and the part of the positioning post 13 passing through the lifting plate 20 can form a positioning section. Based on this structure, since the workpiece pallets are stacked on the lifting plate 20, if they are directly stacked, the stacked workpiece pallets are prone to tipping over during the lifting process of the lifting plate 20. Therefore, in the prior art, a positioning frame structure is generally set around the lifting plate 20, which will interfere with the detection action of the first limiting member 11. Therefore, in this application, by setting a positioning post 13 structure, the positioning section of the positioning post 13 structure passes through the lifting plate 20 and is connected to the positioning hole in the workpiece pallet. After the positioning holes of multiple workpiece pallets correspond one-to-one, the positioning section is sequentially connected to each stacked workpiece pallet structure, which can prevent the workpiece pallets from tipping over during the lifting process of the lifting plate 20.

[0040] More specifically, there are two positioning posts 13, which are arranged side by side. By arranging the two positioning posts 13 side by side, the workpiece tray can be provided with two positioning holes. After the two side by side positioning posts 13 are inserted into the two positioning holes of the workpiece tray, the two positions of the workpiece tray are positioned. In this way, after the workpiece tray is stacked, it is positioned on the lifting plate 20 by the two positioning posts 13, and the positioning structure is stable.

[0041] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
