In some embodiments, the lifting device further comprises a second feeding mechanism 54, the second feeding mechanism 54 being connected to the top end of the lowering mechanism 40 for conveying the tray 200 to the lowering mechanism 40.

In some embodiments, the lifting device further includes a first feeding mechanism 60, and the first feeding mechanism 60 is disposed on the frame 10 for conveying the tray 200 conveyed by the first feeding mechanism 53 to the lifting mechanism 30.
Further, the first feeding mechanism 60 is disposed in the lifting space 11 and located at the bottom end of the lifting mechanism 30, and the first feeding mechanism 60 is connected to the first feeding mechanism 53 to convey the tray 200 conveyed by the first feeding mechanism 53 to the lifting mechanism 30.

It should be noted that the first feeding mechanism 53 includes two pull belts, the two pull belts are also longitudinally arranged along the first direction, the first feeding mechanism 60 partially extends between the two pull belts of the first feeding mechanism 53, and the horizontal height of the two first conveyor belts 62 is the same as that of the pull belts of the first feeding mechanism 53.
As shown in fig. 1, the first feeding mechanism 53 conveys the tray 200 to the left, and when the tray 200 moves to the left end of the first feeding mechanism 53, the tray 200 partially enters the lifting mechanism 30 in the lifting space 11, and the tray 200 is now also in contact with the two first belts 62 of the first feeding mechanism 60, and then the two first belts 62 continue to operate to drive the tray 200 to continue to be conveyed to the left, so that the tray 200 completely enters the lifting mechanism 30 in the lifting space 11.
In practical applications, the first feeding mechanism 60 further includes a first feeding driving element 63, and the first feeding driving element 63 is disposed on the first bottom plate 61 and is simultaneously in transmission connection with the two first belts 62 to drive the two first belts 62 to move, so as to convey the tray 200 along the first direction.
Specifically, the first feed drive 63 is a motor.
In some embodiments, the lifting device further includes a second feeding mechanism 70, and the second feeding mechanism 70 is disposed on the frame 10 for conveying the tray 200 conveyed by the descending mechanism 40 to the second discharging mechanism 52.

In addition, it can be understood that the first feeding mechanism 60 and the second feeding mechanism 70 both adopt a conveyor belt conveying manner, and the first feeding mechanism 60 and the second feeding mechanism 70 both convey the tray 200 in the horizontal direction, so in order to ensure that the first feeding mechanism 60 can convey the tray 200 to the lifting mechanism 30 and the lowering mechanism 40 can convey the tray 200 to the second feeding mechanism 70, the first feeding mechanism 60 and the second feeding mechanism 70 are disposed at the bottom ends of the lifting mechanism 30 and the lowering mechanism 40.

When the first bearing assembly 21 and the second bearing assembly 22 are in the reset state, the lifting mechanism 30 drives the first bearing assembly 21 to descend, and the descending mechanism 40 drives the second bearing assembly 22 to ascend.
Initially, the first bearing assembly 21 is located at the bottom end of the lifting mechanism 30, and is in a bearing state, the tray 200 is borne on the first bearing assembly 21, then the lifting mechanism 30 drives the first bearing assembly 21 to ascend, and after the ascending of the tray 200 is completed, the tray 200 is taken down from the first bearing assembly 21. The lifting mechanism 30 then drives the first carrier assembly 21 to switch to the reset state, and drives the first carrier assembly 21 in the reset state to descend until returning to the original position and switching to the carrier state again.
Similarly, initially, the second carrying assembly 22 is located at the top end of the descending mechanism 40 and is in a carrying state, the tray 200 is carried on the second carrying assembly 22, then the descending mechanism 40 drives the second carrying assembly 22 to descend, and after the descending of the tray 200 is completed, the tray 200 is taken down from the second carrying assembly 22. The descending mechanism 40 drives the second carriage assembly 22 to switch to the reset state, and drives the second carriage assembly 22 in the reset state to descend until the initial position is reached and the carriage state is switched again.
In some embodiments, the first bearing assembly 21 includes a first bearing unit 23 and a second bearing unit 24, the lifting mechanism 30 is in transmission connection with both the first bearing unit 23 and the second bearing unit 24, and the first bearing unit 23 and the second bearing unit 24 are arranged at intervals along the first direction.
When the first carrying assembly 21 is in the carrying state, the first carrying unit 23 and the second carrying unit 24 can respectively carry opposite ends of the tray 200 along the first direction, and the lifting mechanism 30 can drive the first carrying unit 23 and the second carrying unit 24 to ascend synchronously.

When the first carrying assembly 21 is in the carrying state, the first carrying unit 23 and the second carrying unit 24 are respectively located at two opposite inner sides of the first circulating assembly 32 and the second circulating assembly 33 to respectively carry two opposite ends of the tray 200 along the first direction, and the lifting driving assembly 31 can drive the first carrying unit 23 and the second carrying unit 24 to ascend synchronously.
When the first bearing assembly 21 is in the reset state, the first bearing unit 23 and the second bearing unit 24 are respectively located at two opposite outer sides of the first circulating assembly 32 and the second circulating assembly 33, and the lifting driving assembly 31 can drive the first bearing unit 23 and the second bearing unit 24 to descend synchronously.
As will be understood from fig. 3, the lifting drive assembly 31 drives the first carrying unit 23 and the second carrying unit 24 to ascend and descend cyclically and reciprocally through the first circulating assembly 32 and the second circulating assembly 33, respectively, and when the first carrying unit 23 and the second carrying unit 24 ascend synchronously, the first carrying unit 23 and the second carrying unit 24 are positioned inside the first circulating assembly 32 and the second circulating assembly 33, so that the tray 200 positioned between the first circulating assembly 32 and the second circulating assembly 33 can be carried.
After the lifting mechanism 30 lifts the tray 200 and takes the tray 200 off, the lifting driving assembly 31 continues to move, and drives the first carrying unit 23 and the second carrying unit 24 to move to two outer sides of the first circulating assembly 32 and the second circulating assembly 33, respectively, and drives the first carrying unit 23 and the second carrying unit 24 to descend, in which process the first carrying assembly 21 is in a reset state. Until it descends to the bottom end and returns to the two inner sides of the first and second circulating assemblies 32 and 33 facing each other, i.e., the first carrying assembly 21 is put into the carrying state again to carry the tray 200.
In some embodiments, the lifting driving assembly 31 includes a lifting driving member 311, a first driving gear 312 and a second driving gear 313, the lifting driving member 311 is disposed on the frame 10 and is in transmission connection with the first driving gear 312 and the second driving gear 313, the first driving gear 312 is engaged with the first circulating assembly 32, and the second driving gear 313 is engaged with the second circulating assembly 33, so as to drive the first circulating assembly 32 and the second circulating assembly 33 to move simultaneously through the lifting driving member 311.
In some embodiments, the first circulating assembly 32 includes a first synchronous belt 321, a first driven gear 322 and two first synchronous wheels 323, the two first synchronous wheels 323 are arranged at intervals along the vertical direction, the first synchronous belt 321 is connected between the two first synchronous wheels 323, the first bearing unit 23 is fixedly connected with the first synchronous belt 321, the first driven gear 322 is fixedly connected with the first synchronous wheel 323 at the bottom, and the first driving gear 312 is engaged with the first driven gear 322.

In this way, the first timing belt 321 and the second timing belt 331 can be simultaneously driven to rotate by the lifting driving member 311. In addition, it can be understood that the rotation directions of the first and second timing belts 321 and 331 are opposite, so that the first and second carrier units 23 and 24 located inside the first and second timing belts 321 and 331 are driven to ascend synchronously, and the first and second carrier units 23 and 24 located outside the first and second timing belts 321 and 331 are driven to descend synchronously.
