The two pallet lifting assemblies 1 enter the first working state, and the conversion of one pallet 6 is completed.

Specifically, the logistics line of the present application can be a logistics line divided into two sides AB in the battery industry to distinguish the AB side battery cells. Furthermore, the logistics line of the present application is built on the ground with a certain height, and the two logistics lines have at least one adjacent and equal height position. The conversion device of the present application is preferably set at a position where the two point logistics lines are adjacent and equal height.

More specifically, since the structures, installation methods and working principles of the lifting components on the two logistics lines are the same, the pallet lifting component 1 of one logistics line is used as an example for explanation:

The pallet lifting assembly 1 is located below the pallet 6 transferred on the logistics line. The pallet lifting assembly 1 includes a lifting cylinder 11, a lifting mounting plate 12, and a lifting lifting plate 13. The lifting mounting plate 12 is fixedly installed on the logistics line, and the length direction of the lifting mounting plate 12 is defined to be parallel to the conveying direction of the corresponding logistics line, and the width direction of the lifting mounting plate 12 is defined to be perpendicular to the conveying direction of the corresponding logistics line. Side fixing sheet metals 16 are fixedly provided on both sides of the width direction of the lifting mounting plate 12, and the side fixing sheet metals 16 are fastened to the frame of the logistics line through a connecting piece, so as to realize the horizontal fixing of the lifting mounting plate 12 below the logistics line.

Furthermore, the lifting cylinder 11 is horizontally mounted on the jacking mounting plate 12, and the output rod of the lifting cylinder 11 vertically passes through the jacking mounting plate 12 and is fixedly connected to the jacking lifting plate 13. When the lifting cylinder 11 is started, the output rod of the lifting cylinder 11 moves vertically upward, thereby lifting the jacking mounting plate 12 upward, and then the pallet 6 on the logistics line can be lifted.

Furthermore, a linear bearing guide 14 and a hydraulic buffer 15 are provided between the jacking mounting plate 12 and the jacking lifting plate 13, and the extension direction of the linear bearing guide 14 and the hydraulic buffer 15 are parallel to the extension direction of the output rod of the lifting cylinder 11. A set of linear bearing guides 14 are provided on both sides of the lifting cylinder 11, and the two sets of linear bearing guides 14 are symmetrically arranged with the lifting cylinder 11 as the symmetry axis, thereby improving the stability of the movement of the jacking mounting plate 12. A set of hydraulic buffers 15 are provided on both sides of the lifting cylinder 11, and the two sets of hydraulic buffers 15 are symmetrically arranged with the lifting cylinder 11 as the symmetry axis, thereby reducing mechanical vibration and reducing mechanical operation noise.

Furthermore, the lifting and lowering plate 13 is provided with rollers 4, and multiple rollers 4 are arranged at intervals along the connection direction of the two logistics lines on the lifting and lowering plate 13. The connection direction of the two logistics lines is parallel to the width direction of the lifting and lowering mounting plate 12, and the axial direction of any roller 4 is parallel to the direction of the logistics line where it is located. Specifically, a roller 4 mounting plate is vertically fastened on both sides of the length direction of the lifting and lowering plate 13, and a group of rollers 4 is respectively arranged on the inner side walls of the two roller 4 mounting plates. Multiple rollers 4 are arranged at equal intervals in the width direction of the lifting and lowering plate 13. The two groups of rollers 4 are used for the movement of the pallet 6 and the positioning of the movement trajectory of the pallet 6. When the pallet 6 moves from one logistics line to another logistics line, the two groups of rollers 4 arranged on the lifting and lowering plate 13 can support and guide the moving pallet 6 on the one hand, and improve the convenience of the movement of the pallet 6 on the other hand.

The transition assembly 2 of the technical solution of the present application plays a transition role in the process of transporting the pallet 6. The transition assembly 2 includes a transition mounting frame 21 and rollers 4. The transition mounting frame 21 is arranged between the two pallet lifting assemblies 1. A plurality of rollers 4 are arranged on the transition mounting frame 21 at intervals along the direction of the connection between the two pallet lifting assemblies 1.

The axial direction of any roller 4 is horizontally perpendicular to the direction of the connection between the two pallet lifting assemblies 1, thereby being able to guide the pallet 6 to move along the direction of the connection between the two logistics lines. Preferably, the height of the transition assembly 2 is the same as the height of the pallet lifting assembly 1 when it is in the second working state.

In order to improve the working stability of the pallet lifting assembly 1, a blocking cylinder 5 is provided at the pallet lifting assembly 1 of any logistics line. The blocking cylinder 5 includes a first working state and a second working state. When the blocking cylinder 5 is in the first working state, the height of the top of the blocking cylinder 5 is lower than the height of the logistics line. When the blocking cylinder 5 is in the second working state, the height of the top of the blocking cylinder 5 is higher than the height of the logistics line. When the pallet 6 needs to be converted, the blocking cylinder 5 is started, and after the pallet 6 is blocked, the two pallet lifting assemblies 1 are started again.

As shown in Figure 3, the dial assembly 3 of the technical solution of the present application is used to move the pallet 6 to be converted. The dial assembly 3 includes a cylinder mounting plate 31 and a lever device 32. The cylinder mounting plate 31 is horizontally fixedly installed above two adjacent logistics lines. Specifically, a plurality of fixed guide rods 33 are vertically fastened downward on the peripheral side of the cylinder mounting plate 31. Any fixed guide rod 33 is fastened to the frame of the logistics line, thereby realizing the horizontal fixed installation of the cylinder mounting plate 31.

Two groups of lever devices 32 are provided on the cylinder mounting plate 31. The movement directions of the two groups of lever devices 32 are parallel to the connection direction of the two logistics lines. One lever device 32 moves the pallet 6 on one logistics line to the other logistics line, and the other lever device 32 moves the pallet 6 on the other logistics line to one logistics line. It should be noted that the lever device 32 includes a rodless cylinder 321 and a lever 322. The lever 322 is horizontally arranged. The length direction of the lever 322 is parallel to the conveying direction of the logistics line. The height of the bottom of the lever 322 is less than or equal to the height of the top of the pallet 6 on the corresponding logistics line. The rodless cylinder 321 drives the lever 322 to move along the connection direction of the two logistics lines.

The rodless cylinder 321 is fixedly mounted on the top of the cylinder mounting plate 31 through a cylinder bracket, and the lever device 32 also includes a clamping claw connecting plate 323, a clamping claw connecting block 324 and a guide rail 325. The clamping claw connecting plate 323 is fixedly connected to the movable block of the rodless cylinder 321, and the clamping claw connecting block 324 connects the clamping claw connecting plate 323 and the lever 322. It should be noted that a plurality of clamping claw connecting blocks 324 are arranged on one clamping claw connecting plate 323, and a through slot for allowing the clamping claw connecting block 324 to pass through is arranged on the cylinder mounting plate 31, thereby realizing the clamping claw connecting plate 323 located above the cylinder mounting plate 31 and the lever 322 located below the cylinder mounting plate 31 to be fastened and connected. It should be further noted that the length direction of the through slot on the cylinder mounting plate 31 for allowing the clamping claw connecting block 324 to pass through is parallel to the movement direction of the lever 322.

The guide rail 325 is arranged on the cylinder mounting plate 31 , the length direction of the guide rail 325 is parallel to the movement direction of the lever device 32 , and the clamp connecting plate 323 is slidably connected to the guide rail 325 , thereby improving the stability of the movement of the lever 322 .

Working principle: when the number of pallets 6 on one of the logistics lines is too large and the number of pallets 6 on the other logistics line is too small, the blocking cylinder 5 on the logistics line with too many pallets 6 starts to the second working state to block the next pallet 6 on the logistics line, and the two lifting cylinders 11 start to put the two pallet lifting assemblies 1 in the second working state, thereby lifting the blocked pallet 6. At this time, the rodless cylinder 321 corresponding to the logistics line starts to drive the lever 322 to move toward the direction close to the other logistics line. The lifted pallet 6 moves to the lifting and lifting plate 13 of the target pallet lifting assembly 1 through the transition assembly 2 under the action of the lever 322. After that, the two pallet lifting assemblies 1 enter the first working state, and the conversion device is reset, thus completing the conversion of one pallet 6.
