[0029] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0030] This embodiment provides a stacking device for handling and stacking the items to be stacked.

[0031] Such as Figures 1 to 3As shown in the figure, the stacking device includes a transportation mechanism 1, a carrying mechanism 2, and a handling mechanism 3. The transportation mechanism 1 is used to transport the items to be stacked 5, so as to transport the items to be stacked 5 from the outside to the stacking device. The carrying mechanism 2 is arranged at intervals below the transportation mechanism 1 and is used to carry the items to be stacked 5. Among them, the handling mechanism 3 is arranged between the transportation mechanism 1 and the carrying mechanism 2, and the handling mechanism 3 includes a turntable 31 and a robotic arm 32. The robotic arm 32 is arranged on the turntable 31. Furthermore, the turntable 31 can drive the robotic arm 32 to rotate in a vertical plane with the turntable 31 as the axis, so as to carry and stack the items to be stacked 5 from the transportation mechanism 1 onto the carrying mechanism 2. In this way, the stacking of multiple items to be stacked 5 on the carrying mechanism 2 is realized. During this process, the turntable 31 can always drive the robotic arm 32 to rotate, so that the robotic arm 32 has no pause during the process of picking and placing the items to be stacked 5, thereby avoiding time stay and improving the stacking efficiency of the items to be stacked 5. Optionally, the turntable 31 includes a turntable body and a driving motor. The driving end of the driving motor is connected to the turntable body to drive the turntable body to rotate. Further optionally, the item to be stacked 5 is a lithium battery composite sheet. Of course, the item to be stacked 5 can also be other devices, which are not specifically limited in this embodiment.

[0032] Furthermore, the transportation mechanism 1 includes a first vacuum adsorption belt assembly 11 and a second vacuum adsorption belt assembly 12. The item to be stacked 5 can be transported from the first vacuum adsorption belt assembly 11 to the second vacuum adsorption belt assembly 12. Among them, the item to be stacked 5 can be adsorbed on the upper surface of the first vacuum adsorption belt assembly 11, and the item to be stacked 5 can also be adsorbed on the lower surface of the second vacuum adsorption belt assembly 12. Thus, when the item to be stacked 5 is transported from the first vacuum adsorption belt assembly 11 to the second vacuum adsorption belt assembly 12, the item to be stacked 5 can be changed from being adsorbed and transported from below to being adsorbed and transported from above, so as to facilitate the robotic arm 32 to directly carry away the item to be stacked 5 from below the second vacuum adsorption belt assembly 12. Specifically, during the movement of the item to be stacked 5, the robotic arm 32 can adopt a chasing method to pick up the material, so as to avoid the robotic arm 32 from pausing during the material picking process.

[0033] Furthermore, a plurality of robotic arms 32 are provided. The plurality of robotic arms 32 are arranged at intervals on the outer periphery of the turntable 31. Thus, during the rotation of the turntable 31, the plurality of robotic arms 32 can sequentially pick up the items to be stacked 5 on the transportation mechanism 1, so as to improve the efficiency of the stacking device in carrying and stacking the items to be stacked 5. Optionally, the distance between two adjacent robotic arms 32 is the same, so as to facilitate the plurality of robotic arms 32 to carry the plurality of items to be stacked 5 on the transportation mechanism 1 one by one correspondingly, so as to avoid misalignment and missing the transportation of the items to be stacked 5. Among them, the distance between two adjacent items to be stacked 5 on the transportation mechanism 1 is the same.

[0034] As Figure 2As shown in the figure, the robotic arm 32 includes a base 321, an adjustment arm 322, and a vacuum suction cup 323. The base 321 is disposed on the turntable 31. One end of the adjustment arm 322 is rotatably disposed on the base 321, and the vacuum suction cup 323 is rotatably disposed at the other end of the adjustment arm 322. Thus, the vacuum suction cup 323 can rotate in a vertical plane with the turntable 31 as the axis, and the vacuum suction cup 323 is used to adsorb the workpiece to be stacked 5 to ensure the stability of the workpiece to be stacked 5 during the handling process. Among them, through the adjustment of the adjustment arm 322, the vacuum suction cup 323 can meet the requirements for the position of the vacuum suction cup 323 during the rotation process.

[0035] As Figure 3 shown, the carrying mechanism 2 includes a placing table 21 and a rectifying mechanism 22. The placing table 21 is disposed at the driving end of the rectifying mechanism 22. Further, the rectifying mechanism 22 can drive the placing table 21 to move. Among them, the placing table 21 is used to carry the workpiece to be stacked 5, and the rectifying mechanism 22 is used to adjust the spatial position of the placing table 21. Thus, when the workpiece to be stacked 5 is placed on the placing table 21, rectifying and positioning of the workpiece to be stacked 5 can be achieved, and the stacking accuracy of the workpiece to be stacked 5 can be improved. Optionally, the rectifying mechanism 22 is an XYZ moving platform. Thus, when adjusting the position of the placing table 21 in the horizontal plane through the XYZ moving platform, the position of the placing table 21 can also be adjusted in the vertical direction to ensure that the horizontal height of each workpiece to be stacked 5 is the same during the stacking process of the workpiece to be stacked 5, and further improve the stacking accuracy of the workpiece to be stacked 5. Specifically, during the movement of the workpiece to be stacked 5, the robotic arm 32 can use the chasing and placing method for feeding to avoid pauses during the feeding process of the robotic arm 32.

[0036] As Figure 1 shown, the stacking device further includes a CCD mechanism 4. The CCD mechanism 4 is used to collect the position signals of the workpiece to be stacked 5, and the CCD mechanism 4 is signal-connected to the rectifying mechanism 22. Thus, the CCD mechanism 4 can transmit the position signals of the workpiece to be stacked 5 to the rectifying mechanism 22, so that the rectifying mechanism 22 adjusts the spatial position of the placing table 21 according to the position signals of the workpiece to be stacked 5, and further realizes the rectifying function of the rectifying mechanism 22. Specifically, the CCD mechanism 4 includes a CCD camera and a light source assembly. The CCD camera is used to obtain the spatial position image of the workpiece to be stacked 5, so as to realize the collection of the position signals of the workpiece to be stacked 5. Among them, the light source assembly is used to provide light sources to improve the brightness of the workpiece to be stacked 5, facilitating the shooting of the workpiece to be stacked 5 by the CCD camera. Optionally, the CCD mechanism 4 and the handling mechanism 3 are disposed opposite to each other in the horizontal direction, so that the CCD mechanism 4 can directly detect the workpiece to be stacked 5 carried by the robotic arm 32, facilitating the positioning of the movement of the workpiece to be stacked 5 by the CCD mechanism 4. During the process of the robotic arm 32 handling the workpiece to be stacked 5, the CCD mechanism 4 can identify the horizontal offset, vertical offset, and tilt offset of the workpiece to be stacked 5, and then feedback the offset information to the rectifying mechanism 22.

[0037] Obviously, the above-mentioned embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
