Description

Technical Field

[0001] The present invention relates to the technical field of automated equipment, in particular to a battery cartoning machine. Background Art

[0002] When the battery production is completed, it will be transported to the battery packaging station through the conveyor line, and four batteries will be packaged as a group. The packaged batteries are transported to the boxing station through the battery loading device, and then these batteries are stacked in rows and placed in paper boxes.

[0003] When paper boxes leave the factory, they are cut from cardboard and folded on all four sides for easy storage and transportation. The outer ends of the four sides are then folded inward a second time to form a paper box with an open top. Existing battery paper boxes are mostly folded manually, which is not only time-consuming and labor-intensive, but also inefficient. Manually folded paper boxes are also prone to creases, which affects the quality of the paper boxes.

[0004] Existing battery loading devices only have a conveying function and cannot automatically stack the batteries. After the batteries are transported to the boxing station, they still need manual operation. Workers stack the appropriate number of batteries according to the size of the paper box and then pack them into the paper box. This boxing method is very cumbersome, not only time-consuming and labor-intensive, but also inefficient. Summary of the Invention

When the fixed seat 411 moves to the unloading station, the unloading cylinder 431 only needs to drive the unloading push plate 432 horizontally to overcome the magnetic attraction module and push the boxed carton and batteries into the conveyor track 433.

[0074] The present invention uses a cardboard conveying mechanism 22 to absorb the cardboard at the bottom of the material rack 21 and convey it to the carton folding mechanism 23. The carton folding mechanism 23 folds the cardboard into a carton and conveys it to the battery cartoning station of the battery cartoning device 4. The fixed seat 411 rotates to the battery cartoning station after receiving the carton. During this process, the battery stacking mechanism 32 vertically stacks the batteries conveyed by the battery feeding track 31 and conveys them to the battery cartoning station of the battery cartoning device 4 through the battery feeding mechanism 33. The stacked batteries are loaded into the carton. Then the fixed seat 411 continues to rotate to the unloading station, and the unloading assembly 43 moves the unpacked carton and batteries out of the fixed seat 411. The carton folding, battery loading, stacking and cartoning processes of the present invention are fully automatic and do not require manual operation. This is not only efficient but also saves time and effort.

[0075] The specific workflow of the present invention is as follows: First, the first cardboard conveying cylinder drives the cardboard suction plate to rotate, allowing the first vacuum suction nozzle to contact the cardboard at the bottom of the material rack. After the first vacuum suction nozzle is attached to the cardboard, the first cardboard conveying cylinder drives the cardboard suction plate to rotate in the opposite direction, pulling the cardboard from the material rack and rotating the cardboard to a horizontal position. The first vacuum suction nozzle then releases its suction on the cardboard, and the second cardboard conveying cylinder drives the cardboard push rod to move horizontally, pushing the cardboard horizontally to the first folding assembly. Then, the first lifting cylinder drives the first folding plate to move vertically upward, pushing the cardboard into the folding cavity of the first forming seat, completing the first fold of the cardboard on all four sides. Next, the first side folding cylinder drives the two first side folding plates to move toward each other, folding the outer ends of the two long sides of the carton on the first forming seat inward multiple times. During this process, the horizontal folding cylinder drives the second side folding plate to move horizontally, folding the outer ends of the two short sides of the carton on the second forming seat inward. The flip folding cylinder drives the third side folding plate to flip, folding the outer ends of the two folded short sides inward again, completing the folding of the carton. Then, the vertical lifting cylinder drives the first forming seat and the second forming seat to rise synchronously, and then the carton horizontal moving cylinder drives the first sliding seat to move along the first slide rail, so that the first forming seat is located above the first support seat, and the second forming seat is located above the second support seat, and then the vertical lifting cylinder drives the first forming seat and the second forming seat to descend synchronously, so that the carton that has been preliminarily folded in the first forming seat is put on the first support seat, and the carton that has been completely folded in the second forming seat is put on the second support seat; then the second vacuum suction nozzles in the first forming seat and the second forming seat release the adsorption of the carton, and the vertical lifting cylinder drives the first forming seat and the second forming seat to rise synchronously, so that the two cartons are separated from the folding cavity of the first forming seat and the second forming seat. Finally, the carton horizontal moving cylinder and the vertical lifting cylinder drive the first forming seat and the second forming seat to reset. After the reset, the second forming seat will press the carton on the first support seat into its folding cavity to facilitate the next folding of the second folding component; the carton on the second support seat will be moved to the carton loading station of the battery box loading device under the drive of the horizontal driving cylinder, and finally the vertical driving cylinder drives the second support seat to move vertically upward, and send the carton into the groove of the fixed seat, and it will be adsorbed by the vacuum suction cup. Finally, the turntable rotates circumferentially to the battery box loading station.

[0076] During the above process, the battery loading rail will transport the batteries to the loading station under the stacking cavity, and then the lifting cylinder will drive the lifting plate to pass through the through hole upwards, and lift a row of batteries at the battery loading station to the stacking cavity, and then the two flat support cylinders will drive the flat support plates to extend into the lower sides of this row of batteries, thereby lifting the batteries in the stacking cavity; then the lifting cylinder drives the lifting plate to reset, and after the battery loading rail transports a new row of batteries to the loading station under the stacking cavity, the two flat support cylinders will drive the flat support plates to exit the stacking cavity. At this time, the previous row of batteries will be stacked with the new row of batteries, and then the lifting cylinder will drive the lifting plate to lift it upwards, and lift the new row of batteries to the stacking cavity again, and repeat the above operations. The batteries will be stacked up layer by layer; since a movable pressing plate is provided in the stacking chamber, a gradually rising step is provided at the bottom of the movable pressing plate, and the height and width of the step are the same as the diameter of the battery, so that when the batteries in the stacking chamber are stacked, the number of layers will increase successively along the battery conveying direction, and the number of steps is consistent with the number of layers to be stacked, so that the number of stacked layers of the frontmost battery is consistent with the required number of layers, at this time the pushing cylinder drives the pushing plate to extend into the channel, and pushes the batteries in the stacking chamber toward the battery loading mechanism the distance of a group of batteries, thereby pushing the frontmost stacked battery out of the stacking chamber, and then the battery loading mechanism transports the stacked batteries to the battery boxing station of the battery boxing device, and pushes them flatly into the paper box on the fixed seat.

[0077] After the battery packing is completed, the drive unit drives the turntable to continue to rotate in a circular direction, so that the fixed seat rotates to the unloading station, the vacuum suction cup releases the adsorption of the paper box, and the unloading cylinder drives the unloading push plate horizontally to overcome the magnetic force of the magnetic suction module, and move the packed paper box and batteries out of the fixed seat and push them into the conveyor track.
