In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

In addition, embodiments and features of embodiments in the present application may be combined with each other without conflict.

The embodiment of the application provides an alternate loading and unloading device which can be applied to automatic loading of parts such as motors. It should be noted that in some automatic assembly processes, batch operations need to be performed on motor parts, and at present, the feeding device of many existing automatic assembly devices can only feed a group of motors or a single motor at a time, which seriously affects the production efficiency of products. The alternately feeding and discharging device provided by the application can continuously feed a plurality of groups of parts, and improves the efficiency of automatic assembly. The alternate loading and unloading device is specifically described below with reference to the accompanying drawings.

Referring to fig. 1, the alternate loading and unloading device includes: the feeding device comprises a frame 100, a plurality of translation feeding mechanisms 200 and a feeding mechanism 300. The translation feeding mechanism 200 comprises a guide rail 210 horizontally arranged on the frame 100, a moving frame 220 capable of sliding and translating on the guide rail 210, a driving element 230 for driving the moving frame 220 to move, and a material bracket 240 in one-to-one correspondence with the moving frame 220; the material holder 240 is placed on the moving frame 220; the material bracket 240 is used for placing a group of parts to be loaded; the driving element 230 is used to drive the moving frame 220 to move to or from a predetermined loading area. The feeding mechanism 300 is disposed at the bottom of the feeding area, and is capable of lifting the material carrier 240 on the moving rack 220 located on the feeding area to a predetermined feeding height, and lowering and retracting from the feeding height to an initial height to replace the material carrier 240 on the corresponding moving rack 220.

In operation, the plurality of material carriers 240 of the plurality of translational feeding mechanisms 200 can be used for placing the parts to be fed, each material carrier 240 is correspondingly provided with a group of parts, as shown in the accompanying drawings, and each material carrier 240 is provided with four motor parts. The number of parts that can be placed on each material holder 240 may be determined according to the actual situation. During feeding, the plurality of translation feeding mechanisms 200 sequentially push the material brackets 240 to the feeding area, then the feeding mechanism 300 lifts the material brackets 240 to a preset feeding height, and then the feeding mechanism 300 returns to place the material brackets 240 on the corresponding movable frames 220.

Specifically, for the first translational feeding mechanism 200, under the driving of the driving element 230, the moving frame 220 moves along the guide rail 210 toward the side close to the feeding area until entering the feeding area, in this process, the moving frame 220 carries the material carrier 240 thereon into the feeding area, the feeding mechanism 300 located at the bottom of the feeding area is lifted upwards, and the material carrier 240 on the moving frame 220 is lifted to a predetermined feeding height, at this time, the parts on the material carrier 240 can be taken and assembled by the robot. After the parts are removed, the drive member 230 begins to descend back, during which the material carriers 240 are replaced on the corresponding moving racks 220, and the final drive member 230 descends back to the original height. Then, the driving element 230 drives the moving frame 220 to retract away from the feeding area until returning to the initial position, so as to complete the feeding of the first group of parts on the first translational feeding mechanism 200. After the first translational feeding mechanism 200 finishes feeding, then the second translational feeding mechanism 200 starts feeding the second set of parts, … …, so that each translational feeding mechanism 200 feeds a set of parts thereon, and the process is similar to the feeding process of the first translational feeding mechanism 200, and is not repeated here. The continuous feeding of a plurality of groups of parts is realized in the feeding process.

Referring to fig. 2-4, in some embodiments of the present application, a plurality of translational feed mechanisms 200 are arranged in pairs; the pair of translational feed mechanisms 200 is constituted by a left translational feed mechanism 200a and a right translational feed mechanism 200b arranged at the same height; the guide rails 210 of the left side translational feeding mechanism 200a and the right side translational feeding mechanism 200b are arranged to extend in the left-right direction.
