Description

Technical Field

[0001] The utility model relates to a cylindrical battery automatic loading and palletizing device, belonging to the technical field of battery loading and transportation. Background Art

[0002] After the production and detection of cylindrical batteries, they need to be palletized and transported after being carried by trays. The tray loading is used for picking up the cylindrical batteries on the conveyor line and loading them into the loading slots on the trays, and the palletizing is used for palletizing the fully loaded trays, that is, realizing the stacking of multiple trays.

[0003] In traditional production lines, automated production lines are used for the streamlined transportation of trays. When passing through the loading station, the battery casings are automatically loaded onto the trays, and after loading, they are output by the conveyor line to the palletizing station for palletizing operations. When operating in this way, individual trays need to be loaded sequentially at the front end, and a pallet bottom support is required during palletizing at the rear end. Therefore, the overall production line has high requirements for the layout space, and the sequential feeding of trays at the front end is also time-consuming and laborious.

[0004] In addition, since pallets are required for palletizing the trays, only the palletizing operation of the trays on a single-station pallet can be achieved, and material caching cannot be realized, which affects the capacity of the overall production line. When the pallet is used to carry and palletize the trays for turnover, a forklift turnover operation space also needs to be provided, resulting in waste of space resources.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0041] The following further elaborates on the present application with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the relevant utility model and not for limiting the utility model. Additionally, it should be noted that for the sake of description, only the parts related to the relevant utility model are shown in the drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0042] The present utility model provides a cylindrical battery automatic loading and palletizing device, as Figures 1 to 8 shown, which includes a cylindrical battery automatic conveying line 1 and a loading and palletizing device that cooperates with the cylindrical battery automatic conveying line.

[0043] The loading and palletizing device includes a feeding ground roller line 2 for feeding empty pallet stacks, a discharging ground roller line 3 for discharging loaded pallet stacks, a pallet switching position ground roller line 4 provided between the discharging end of the feeding ground roller line and the feeding end of the discharging ground roller line and having a buffer station 41 and a loading station 42, a first transfer mechanism 5 for transferring empty pallets between the discharging end of the feeding ground roller line and the buffer station, a second transfer mechanism 6 for transferring loaded pallets between the loading station and the feeding end of the discharging ground roller line, and a transfer and loading mechanism 7 for transferring and loading cylindrical batteries between the loading station and the cylindrical battery automatic conveying line. The feeding ground roller line and the discharging ground roller line are arranged in parallel.

[0044] The first transfer mechanism 5 includes a first transfer table 51 having a linear switching displacement and a lifting displacement, and a first picking part 52 provided on the first transfer table.

[0045] The second transfer mechanism 6 includes a second transfer table 61 with linear switching displacement and lifting displacement, and a second picking part 62 arranged on the second transfer table.

[0046] The transfer and loading mechanism 7 includes a loading and transfer table 71 with linear switching displacement and lifting displacement, and a plurality of negative pressure adsorption parts 72 arranged on the loading and transfer table for adsorbing cylindrical batteries.

[0047] Specific implementation process and principle description:

[0048] As Figures 1 to 3 shown, the tray 100 is a loading tray structure with a matrix-type loading cavity. The stack of empty trays is the stack of empty trays, and the stack of loaded trays is the stack of loaded trays. The ground roller conveyor is a conveyor line composed of two parallel and spaced conveyor belts.

[0049] When performing the automated loading and palletizing operation, first, the feeding ground roller conveyor 2 transports the stack of empty trays to the position opposite to the buffer station 41. At this time, the first transfer table 51 transfers to the top of the loading position of the feeding ground roller conveyor 2 and picks up the top empty tray through the first picking part 52, and transfers the empty tray to the buffer station 41.

[0050] The tray switching position ground roller conveyor 4 transfers the empty tray on the buffer station 41 to the loading station 42. At this time, the transfer and loading mechanism 7 realizes the picking and transfer of the cylindrical batteries on the automated conveyor line 1 of the cylindrical batteries through the displacement of the loading and transfer table 71 and the negative pressure adsorption parts 72, and loads the cylindrical batteries into the trays on the loading station 42.

[0051] When the loading is completed, the loaded tray is turned over by the second transfer mechanism 6. The second transfer table 61 transfers and drives, and the second picking part 62 picks up the loaded tray and places it on the unloading ground roller conveyor 3 for the palletizing operation of the stack of loaded trays. After the palletizing is completed, it is output by the unloading ground roller conveyor 3.

[0052] In this way, the requirements for automated tray turnover, loading, and palletizing of loaded trays are realized, and the operation is efficient and smooth.

[0053] In a specific embodiment, pallet boards 200 are respectively arranged at the bottoms of the stack of empty trays and the stack of loaded trays. Specifically, generally, in order to facilitate palletizing stacking and transfer, pallet boards 200 are used for palletizing empty trays and fully loaded trays, so as to facilitate the transfer by AGV or forklift and meet the structural strength of palletizing.

[0054] For this situation, as Figures 1 to 8 shown, the first picking part 52 is provided with a first compatible picking part 520 for picking up empty trays or pallet boards; the second picking part is provided with a second compatible picking part 620 for picking up loaded trays or pallet boards.

[0055] A pallet transfer mechanism 8 for pallet transfer is provided on the ground roller line at the pallet changing position. The pallet transfer mechanism 8 includes a switching displacement carrier 81 capable of linearly switching displacement and lifting displacement between the buffer station and the loading station, and a pallet picking part 82 for picking up pallets is provided on the switching displacement carrier.

[0056] Specifically, generally, when there are pallets 200 for supporting and stacking, it is necessary to perform forward and reverse pallet loading and unloading through the feeding ground roller line 2 and the unloading ground roller line 3, which is difficult to control and will affect continuous operation.

[0057] In response to this situation, when the empty pallet transfer is completed and only the pallet 200 remains, at this time, the first compatible picking part 520 picks up the pallet 200 and transfers it to the buffer station 41, and then the pallet on the buffer station 41 is transferred to the loading station 42 through the pallet picking part 82. Finally, the pallet is transferred to the unloading ground roller line 3 for discharge by the second compatible picking part 620.

[0058] In this way, one-way continuous turnover operation is realized, and the operation efficiency is guaranteed.

[0059] It should be noted that when transferring the pallet between the buffer station 41 and the loading station 42, the operation method of placing the pallet and then picking it up and transferring it, or docking the first compatible picking part 520 with the pallet picking part 82 and docking the pallet picking part 82 with the second compatible picking part 620 can be adopted. In this way, the transfer is more flexible. The transfer principles of placing and transferring cooperation and non - placing and transferring cooperation belong to the prior art and will not be elaborated here. Only the compatible technical means and implementation mechanisms for pallet transfer and pallet transfer need to be satisfied, and they are all within the protection scope of this case.

[0060] In a specific embodiment, as Figure 5 shown, the first compatible picking part 520 and the second compatible picking part 620 respectively include two picking carrier arms 300 arranged at intervals. A picking jaw body 400 is provided on any picking carrier arm. The two picking jaw bodies have relative displacement, and a reflection photoelectric sensor 500 is provided on any picking jaw body.

[0061] Specifically, generally, the pallet has a double - row cavity for forklift transfer. Therefore, the design of the picking carrier arm 300 is adopted. Its picking jaw body 400 is used for clamping and transferring the pallet 100, and for the pallet, the fork - taking transfer method of passing the picking carrier arm 300 through the double - row cavity can be adopted.

[0062] Of course, in order to improve compatibility, it is also possible to require that the two picking carrier arms 300 have relative adjustment displacement, so as to meet the clamping requirements of different specifications of pallets and different specifications of pallets.

[0063] The reflective photoelectric inductor 500 is used to sense the transfer tray layer by layer to ensure that the top tray is transferred each time. That is, it first moves upward to the top. After sensing an obstruction during the downward movement, it grabs the tray according to the downward travel set by the system.

[0064] In a specific embodiment, the pallet picking part 82 includes two shovel arms 821 arranged at intervals.

[0065] Specifically, when the first compatible picking part 520 and the second compatible picking part 620 perform clamping transfer, after picking up the pallet and aligning it with the shovel arm 821, the pallet transfer docking requirement can be met, thus facilitating the efficient docking transfer of the pallet.

[0066] In a specific embodiment, a locking jaw body 822 is provided on any one of the shovel arms, and the two locking jaw bodies have relative displacement. When the space is limited, etc., the locking jaw body 822 can be used to clamp and transfer the pallet.

[0067] It should be noted that since the tray switching position ground roller line 4 needs to transfer the tray, the lifting displacement of the switching displacement carrier 81 can meet the avoidance requirement.

[0068] In a specific embodiment, the feeding end of the feeding ground roller line 2 and the discharging end of the discharging ground roller line respectively include a turnover station 600 for the latent turnover robot to transfer materials.

[0069] Specifically, the feeding ground roller line 2 and the discharging ground roller line 3 are conveying lines constructed by two circulating material belts spaced apart. Therefore, the reserved space meets the requirement of the turnover station 600. At this time, the AGV can transfer the stack at the turnover station 600, saving valuable layout space and eliminating the need to reserve space for forklifts and other transfer means.

[0070] In a specific embodiment, horizontal blocking cylinder parts 700 for material blocking are respectively provided on the feeding ground roller line and the discharging ground roller line.

[0071] The horizontal blocking cylinder part 700 can slow down and stop the stack, thus realizing a blocking transition and preventing the stack from tilting due to buffering.

[0072] In a specific embodiment, a tray positioning mechanism for positioning the tray on the loading station is provided on the tray switching position ground roller line; the tray positioning mechanism includes a positioning side baffle and an end baffle that are perpendicular to each other, a positioning cylinder with lifting displacement and linear displacement towards the end baffle, and at least one side push cylinder with linear displacement towards the positioning side baffle.

[0073] The composition of the tray positioning mechanism belongs to the prior art, which can achieve the positioning around the tray. Therefore, it will not be elaborated here. Any mechanism that can precisely position the tray on the loading station is within the protection scope of this case, so as to meet the relative position accuracy requirements for the loading of cylindrical batteries, and the tray loading is reliable and stable.

[0074] In a specific embodiment, as Figure 8 shown, the automatic conveying line for cylindrical batteries is provided with an aligning and spacing mechanism 9 for feeding the transfer and loading mechanism; the aligning and spacing mechanism includes an aligning support table 91 and two cooperating rotary spacing screws 92 arranged on both sides of the aligning support table.

[0075] That is, the cylindrical batteries will be conveyed to the aligning support table 91. Under the rotating state of the two cooperating rotary spacing screws 92, precise spacing can be achieved to meet the requirements for the relative position accuracy of picking.

[0076] In a specific embodiment, as Figure 1 and Figure 8 shown, it includes two of the above-mentioned automatic conveying lines 1 for cylindrical batteries. The aligning and spacing mechanisms of the two automatic conveying lines for cylindrical batteries are arranged in parallel at intervals; on the loading and transfer table of the transfer and loading mechanism, there are two alignment carrier plates corresponding to the aligning and spacing mechanism one by one, and a number of negative pressure adsorption parts are arranged on the alignment carrier plates.

[0077] It can realize the turnover and loading of two rows of aligned cylindrical batteries at a time, so the loading operation is more efficient.

[0078] From the above description, it can be found that the utility model can realize automatic loading and palletizing operations. It meets the one-way smooth turnover, realizes the continuous turnover of the tray and the circular return of the pallet, so the operation is more smooth and stable, and the efficiency of the loading and palletizing operations is significantly improved. The overall layout requires less space, can be docked and cooperated with the AGV, and improves the turnover efficiency.

[0079] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, so that a process, method, article or equipment / device comprising a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to these processes, methods, articles or equipment / devices.

[0080] So far, the technical solution of the utility model has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the utility model is obviously not limited to these specific embodiments. Without departing from the principle of the utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the utility model.
