[0033] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only some embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

The first power device 2 and the first transmission device 3 are both installed on the frame 1. The first power device 2 is connected to the first transmission device 3. The first transmission device 3 and the second power device 6 are both installed on the vertical movement structure 7. The vertical movement structure 7 can move on the connecting rails driven by the first transmission device 3;

[0036] One of the second transmission devices 4 is respectively installed on the left and right sides of the vertical movement structure 7. One of the cross arms 8 is respectively installed on the left and right sides of the vertical movement structure 7. The second transmission device 4 is connected to the cross arm 8.

The power transmission structure 5 is respectively connected to the power transmission structure 5, the second transmission device 4, and the second power device 6. The clamping device is installed at one end of the cross arm 8 away from the vertical movement structure 7.

[0037] The two corresponding cross arms 8 are respectively movably installed on the left and right sides of the vertical movement structure 7, that is, the two cross arms 8 are respectively movably installed on the left end and the right end of the vertical movement structure 7. The frame 1 is a hollow frame structure, composed of corresponding support arms on the left and right sides and cross arm beams on the upper and lower sides. Connecting rails are provided on the support arms on the left and right sides. The vertical movement structure 7 can move on the connecting rails. The structures of the de-palletizing mechanism of this embodiment installed on the two support arms are the same.

[0038] The left and right sides of the vertical movement structure 7 are respectively connected to the connecting guide rails on the two support arms of the frame 1. The clamping devices 9 of the two cross arms 8 are aligned with the power turnover box, and jointly clamp the power turnover box to clamp it. The second power device 6 provides power, and the power is transmitted to the second transmission device 4 through the power transmission structure 5. The second transmission device 4 converts the power into driving the cross arm 8 to move horizontally, driving the power turnover box to move horizontally; the first power device 2 provides power for the first transmission device 3. While the first transmission device 3 drives the vertical movement structure 7 to move up and down, it drives the two cross arms 8 to move up and down, and drives the power turnover box clamped by the clamping device 9 of the cross arm 8 to move up and down. By clamping the power turnover box and moving it horizontally and vertically, the power turnover box can be moved above the previous power turnover box to achieve stacking of the power turnover boxes. It can also transfer the stacked power turnover boxes to the conveyor belt, facilitating the transport of multiple power turnover boxes stacked at one time by a movable pallet or conveyor line, which is convenient and fast, improves work efficiency, and realizes a high degree of automation and mechanization.

[0039] The first power device 2 is a first motor 21. The first transmission device 3 includes a first transmission group 31, a first transmission shaft 32, a lifting main sprocket 331, a lifting slave sprocket 332, and a first lifting chain 33. The first transmission shaft 32 is rotatably installed on the frame 1. The first motor 21 is connected to the first transmission shaft 32 through the first transmission group 31. The first lifting chain 33 is connected to the first transmission shaft 32 through the lifting main sprocket 331. The lifting slave sprocket 332 is rotatably installed at the bottom of the frame 1. The lifting main sprocket 331 and the lifting slave sprocket 332 are connected by the first lifting chain 33. Two connecting heads are provided on the first lifting chain 33, and the two connecting heads are respectively installed on the top surface and the bottom surface of the vertical movement structure 7. The first transmission shaft 32 can be installed on the frame 1 through bearings, or can also be directly installed on the frame 1 through clearance connection.

[0040] The first power device 2 can be a motor or other devices capable of providing rotational power. The first transmission group 31 includes a first main sprocket 311, a first chain 312, and a first driven sprocket 313. The first main sprocket 311 is installed on the main shaft of the first motor 21, and the first driven sprocket 313 is installed on the first transmission shaft 32. The first chain 312 connects the first main sprocket 311 and the first driven sprocket 313. The first motor 21 drives the first main sprocket 311 to rotate. The first chain 312 transmits the power of the first main sprocket 311 to the first driven sprocket 313. The first driven sprocket 313 drives the first transmission shaft 32 to rotate, and the first transmission shaft 32 drives the first lifting chain 33 to rotate. There are two connectors on the first lifting chain 33, and the two connectors are opposite in the moving direction. Therefore, the two connectors need to be installed on the top surface and the bottom surface of the vertical movement structure 7 respectively. Under the action of the first transmission shaft 32, the first lifting chain 33 rotates with the first transmission shaft 32. The lifting main sprockets 331 are all installed on the first transmission shaft 32, and the lifting driven sprockets 332 are rotatably installed on the frame 1. The first lifting chain 33 connects the lifting main sprockets 331 and the lifting driven sprockets 332. The lifting main link sprocket can also be integrally formed with the first transmission shaft 32. Under the action of the lifting main sprocket 331, the first lifting chain 33 rotates, and during the rotation of the first lifting chain 33, it drives the vertical movement structure 7 to move up or down.

[0041] In addition, if the first lifting chain 33 is arranged in the middle of the frame 1 and connects the middle of the vertical movement structure 7, it can realize pulling the vertical movement structure 7 up and down. However, the first lifting chain 33 bears a relatively high strength, has a high wear rate during use, and a low safety factor. It is easy to break, and then the vertical movement structure 7 will fall directly, which is likely to cause accidents. Therefore, when designing the present invention, a second lifting chain is designed. The position of the second lifting chain corresponds. That is, the first transmission device 3 further includes a second lifting chain. The second lifting chain is installed on the first transmission shaft 32. There are two connectors on the second lifting chain, and the two connectors are respectively installed on the top surface and the bottom surface of the vertical movement structure 7. The first lifting chain 33 and the second lifting chain are respectively located at both ends of the first transmission shaft 32. The two ends of the first transmission shaft 32 and the two cross arms 8 are installed at positions corresponding to the vertical movement structure 7. The connection position of the second lifting chain and the first lifting chain 33 to the vertical movement structure 7 corresponds. Here, it refers to the left end and the right end of the vertical movement structure 7 as the corresponding positions.

[0054] Specific operation: Place the unpacking and palletizing mechanism of this embodiment between the movable pallet and the conveyor line. When the power turnover box on the conveyor line is conveyed outwards, control the first motor 21 to drive the first lifting chain 33 to rotate. The two connecting heads of the first lifting chain 33 act on the upper mounting rod 71 and the lower mounting rod 72 respectively, driving the cross arm 8 to move to a position flush with the power turnover box closest to the unpacking and palletizing mechanism and at the uppermost position on the conveyor line. Control the second motor 41 to drive the transmission chain 62 to rotate. The transmission chain 62 acts on the first part 81 of the cross arm through the transfer block 65. The first part 81 of the cross arm and the second part 82 of the cross arm move to the position where the power turnover box is to be grabbed. Control the second cylinder 91 to eject, pushing the clamping plate 92 to act on the rotating seat 94 and the rotating shaft 95 on the rotating seat 94, so that the rotating plate 96 moves outwards. The clamping plates 92 on both sides of the second part 82 of the cross arm hold the two sides of the power turnover box, and the rotating plate 96 is inserted into the bottom of the power turnover box, which can support the power turnover box and clamp the power turnover box accurately, stably and safely. In addition, when adjusting the forward and backward movement of the cross arm 8 relative to the mounting seat 75, the telescopic movement of the first cylinder 8212 can also be used to adjust the position of the clamping device 9, so as to be able to more accurately align with the clamping position of the power turnover box for clamping. After the clamping device 9 clamps the power turnover box, the cross arm 8 moves backward, moving the power turnover box above the movable plank road. By controlling the cross arm 8 to move downward, the power turnover box is placed on the movable pallet. The second cylinder 91 retracts, releasing the clamping of the power turnover box, and the power turnover box can be transported safely, reliably and accurately. Usually, manual operation or the methods in the prior art cannot realize the automatic transportation of multiple power turnover boxes at the same time and can only be done manually. This embodiment can also transport multiple turnover boxes at one time or stack the placed power turnover boxes, with high working efficiency, strong reliability and high safety factor. When the power turnover box on the movable pallet needs to be conveyed to the conveyor line, its operation is the same as above and will not be elaborated here.
