[0029] like Figures 1 to 3 As shown, in this embodiment, the present invention includes a main frame 2, within which two lifting cavities 21 are provided that cooperate with the feeding trolley 1. A connecting rod 22 is provided on the upper part of the main frame 2; two sets of lifting components 3, each of which is correspondingly disposed in the corresponding lifting cavity 21, for driving the tray to move up and down; a tray transfer component 4, fixedly connected to the upper part of the main frame 2, for clamping the tray and moving it above the two lifting cavities 21; two sets of clamping components 5, mirror-displayed on the connecting rod 22, with the two sets of clamping components 5 located above the same lifting cavity 21, for fixing the tray for loading and unloading; and several trolley limiting components 6, correspondingly disposed at the lower part of the corresponding lifting cavity 21, each of which cooperates with the feeding trolley 1 for limiting.

[0030] Specifically, the main frame 2 is used to support the overall structure. A guide plate that cooperates with the feeding trolley 1 is provided below the main frame 2. The feeding trolley 1 enters the lifting cavity 21 under the drive of the guide plate. A limit rod is provided below the main frame 2 to limit the entry distance of the feeding trolley 1.

[0031] Two sets of lifting components 3 are used in conjunction with tray transfer components 4. After the feeding trolley 1 enters, the position of the tray is automatically identified, so that the tray can be loaded and unloaded in the two lifting chambers 21. The tray turnover efficiency is high. During the process, no staff assistance is required to replace the tray, realizing automated tray replacement. Two sets of mirrored clamping components 5 are used to clamp and limit the tray on the side near the picking station, improving the stability of the tray during operation and improving picking efficiency. At the same time, multiple trolley limiting components 6 are set below the main frame 2. When the two feeding trolleys 1 are fully pushed in, the trolley limiting components 6 are pushed out, and the limiting wheels 64 cooperate with the feeding trolley 1 to prevent the feeding trolley 1 from moving backward and affecting the loading.

[0032] like Figure 4 As shown, in this embodiment, the lifting assembly 3 includes a lifting plate 31 fixedly connected to the lifting cavity 21, a lifting drive device 32 fixedly connected to the middle of the lifting plate 31, a lifting bracket 33 fixedly connected to the movable end of the lifting drive device 32, and two limiting brackets 34 correspondingly arranged on the corresponding side of the lifting plate 31. The lifting plate 31 is provided with two guide rails 35, each of which slides with the lifting bracket 33. The lifting bracket 33 forms a limiting plate 36 for limiting.

[0033] Specifically, the lifting drive device 32 is an electric slide table, and the limit frame 34 is set on both sides of the lifting drive device 32. The width between the two limit frames 34 is smaller than the width of the tray, so that after the tray enters the lifting cavity 21, the side is aligned with the limit frame 34, which improves the stability of the tray during the up and down movement.

[0034] In this embodiment, both of the upper parts of the two limiting frames 34 are provided with through-beam sensors 37, and both of the lower parts of the two limiting frames 34 are provided with proximity switches 38 for detecting the position of the feeding trolley 1.

[0035] Specifically, the proximity switch 38 is used to sense the entry state of the feeding trolley 1, and the through-beam sensor 37 is used to detect the position of the tray located above, and together with the tray transfer assembly 4, the tray is picked up and moved.

[0036] like Figure 5As shown, in this embodiment, the tray transfer assembly 4 includes a fixed frame 41 fixedly connected to the upper part of the main frame 2, a transfer drive device 42 fixedly connected to the fixed frame 41, a connecting frame 43 fixedly connected to the movable end of the transfer drive device 42, a transfer lifting device 44 fixedly connected to the connecting frame 43, and a gripper frame 45 fixedly connected to the movable end of the transfer lifting device 44. The connecting frame 43 is symmetrically provided with two sliders 46, each slider 46 being guided and engaged with the gripper frame 45. Position sensors 47 for detecting the tray position are fixed on both side walls of the connecting frame 43.

[0037] Specifically, the transfer drive device 42 is a slide motor, the transfer lifting device 44 is a telescopic cylinder, and the position sensor 47 is used to detect the tray gripping status, improve the effectiveness of gripping the tray, and effectively avoid the situation where the tray gripping fails due to the extension stroke of the transfer lifting device 44 being too short.

[0038] like Figure 6 As shown, in this embodiment, the gripper frame 45 includes a mounting plate 451, two gripper plates 452, and four clamping cylinders 453. The mounting plate 451 has a mounting groove 454 in the middle that cooperates with the transfer lifting device 44. The transfer lifting device 44 is engaged with the bottom of the mounting groove 454. One side of the mounting plate 451 is provided with a slide rail 455 that corresponds to and cooperates with the corresponding slider 46. Each gripper plate 452 is correspondingly disposed on the corresponding side of the mounting plate 451. Each clamping cylinder 453 is fixedly connected to the end of the corresponding gripper plate 452. Each clamping cylinder 453 is provided with a clamping claw 456 for clamping the tray.

[0039] Specifically, the clamping cylinder 453 is a telescopic cylinder, and the four sets of gripper frames 45 clamp and grasp the tray in four directions, resulting in high gripping stability.

[0040] like Figure 7 As shown, in this embodiment, the clamping assembly 5 includes a base plate 51 fixedly connected to the connecting rod 22, a sliding cylinder 52 disposed on one side of the base plate 51, a clamping member 53 fixedly connected to the movable end of the sliding cylinder 52, and a pushing member 54 slidably connected to the other side of the base plate 51. The clamping member 53 is provided with an extension plate 55, the extension plate 55 forms a guide groove 56, and the upper part of the pushing member 54 is bolted with a follower cam 57 that guides and cooperates with the guide groove 56.

[0041] Specifically, the sliding cylinder 52 is a telescopic cylinder. A moving rail and a sliding block are provided on the base plate 51. The pusher 54 is fixedly connected to the sliding block. When the sliding cylinder 52 is pushed out, the pusher 54 pushes out synchronously through the follower cam 57 structure, so as to press and position the tray in multiple directions and improve the stability of the cooperation with the material picking mechanism.

[0042] In this embodiment, a connecting groove is formed at the lower end of the clamping member 53, and a clamping block 58 for fixing the position of the tray is detachably connected to the connecting groove.

[0043] like Figure 8 As shown, in this embodiment, the trolley limiting assembly 6 includes a mounting frame 61, a limiting drive device 62, a limiting connecting block 63, and a limiting wheel 64. The mounting frame 61 is fixedly connected to the lower part of the main frame 2, the limiting drive device 62 is fixedly connected to the upper part of the mounting frame 61, a guide block 65 is formed on the lower part of the mounting frame 61, the upper end of the limiting connecting block 63 is fixedly connected to the movable end of the limiting drive device 62, the limiting connecting block 63 and the guide block 65 are guided and cooperated, and the limiting wheel 64 is pivotally connected to the lower part of the limiting connecting block 63.

[0044] Specifically, the limit drive device 62 is a telescopic cylinder, and the limit wheel 64 is locked in place with the preset limit block of the feeding trolley 1 to prevent the trolley from slipping and moving backward after entering, thus affecting the tray loading and unloading process.

[0045] The working principle of this utility model:

[0046] An empty feeding trolley 1 is pushed into the feeding chamber near the pickup station, while a fully loaded feeding trolley 1 is pushed into the feeding chamber away from the pickup station. The lifting bracket 33 of the lifting assembly 3 on the fully loaded tray side is at the bottom, and the lifting bracket 33 of the other lifting assembly 3 is at the top. After both feeding trolleys 1 are fully pushed in, the trolley limiting assembly 6 is pushed out, and the limiting wheel 64 engages with the feeding trolley 1 to prevent the feeding trolley 1 from reversing and affecting the loading. Immediately afterwards, the lifting drive device 32 on the fully loaded side drives the lifting bracket 33 to move upward, and the tray rises until it is automatically stopped after being detected by the through-beam sensor 37. The drive device 42 moves the gripper frame 45 to above the tray. The transfer lifting device 44 extends to bring the gripper frame 45 closer to and pick up the tray. Then the transfer lifting device 44 resets and retracts. The transfer drive device 42 moves the tray to above the empty feeding trolley. The tray is placed on the lifting bracket 33 on the empty side. The through-beam sensor 37 on the side of the feeding bracket detects the tray entering. The sliding cylinders 52 of the two sets of clamping components 5 extend. The clamping plates on both sides clamp the tray from both sides. The two pushers 54 extend simultaneously and press against one side of the tray to cooperate with the loading and unloading of the picking station.

[0047] After loading and unloading a single tray, the uppermost lifting bracket 33 moves down one station, and the through-beam sensor 37 detects that it is in an unloaded state. The lowermost lifting bracket 33 moves up one station, and the above steps are repeated to automatically pick up the tray until all trays have been picked up and unloaded.

[0048] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
