In the figures, the thickness of regions and layers is exaggerated for clarity. Like reference numerals in the figures denote like or similar structures and thus their detailed description will be omitted.

[0026] The features, structures, or characteristics described may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of the present disclosure. However, those skilled in the art will recognize that the technical solutions of the present disclosure may be practiced without one or more of the specific details, or may be implemented using other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the present disclosure.

[0027] The following-described embodiments are of a polygon rotation pulling belt taping mechanism of the present disclosure. This example is only a part of the embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0028] Please refer to Figures 1 to 7, according to an embodiment of the present invention, a polygon rotary tape pulling and attaching mechanism is provided, including a polygon rotary cylinder (not labeled in the figure). The polygon rotary cylinder includes an air-permeable rotary shaft 11 and a plurality of tape adsorption components 12 arranged around the air-permeable rotary shaft 11. The plurality of tape adsorption components 12 together enclose a polygon. The air-permeable rotary shaft 11 has a plurality of air channels 111 extending along its axial direction. Each air channel 111 is correspondingly arranged with each tape adsorption component 12. Each tape adsorption component 12 has a negative pressure adsorption cavity 121. The first end of each air channel 111 is communicated with each negative pressure adsorption cavity 121. A fixing ring 2 is sleeved on the radial outer side of the driving end of the air-permeable rotary shaft 11 (its position remains unchanged, that is, when the air-permeable rotary shaft 11 is driven to rotate, the position of the fixing ring 2 remains unchanged). A tape pulling adsorption control air cavity 21 and a tape placing control air cavity 22 are formed in the fixing ring 2. The negative pressure formed in the tape pulling adsorption control air cavity 21 is used to adsorb the tape to ensure that the tape is pulled when the polygon rotary cylinder rotates. The negative pressure formed in the tape placing control air cavity 22 is used to release the adsorption of the tape on it when the adsorbed tape is placed at the target position of the battery cell. The tape pulling adsorption control air cavity 21 is communicated with the second end of the air channel 111 on the tape pulling side, and the tape placing control air cavity 22 is communicated with the second end of the air channel 111 on the tape attaching side. And the tape pulling adsorption control air cavity 21 and the tape placing control air cavity 22 are independently and controllably communicated with a vacuum suction device (not shown in the figure).

[0029] In this technical solution, by providing a tape pulling adsorption control air cavity 21 and a tape placing control air cavity 22 in the fixing ring 2, the on-off control of the negative pressure adsorption of the corresponding air channels 111 in the air-permeable rotary shaft 11 is realized, without using the structure of separately controlling slip rings and slip sleeves respectively communicated with each air channel 111 in the prior art. The component assembly and air path connection are simplified. The simplified air path connection can also improve the air flow rate and ensure more reliable and stable negative pressure adsorption control.

[0030] It should be noted that the independent and controllable communication of the tape pulling adsorption control air cavity 21 and the tape placing control air cavity 22 with the vacuum suction device can release the adsorption of the tape when the tape is cut and placed at the target position of the battery cell.

[0031] In a specific embodiment, see Figure 1 As shown, the polygon rotary cylinder is a regular hexagon rotary cylinder. At this time, the plurality of tape adsorption components 12 enclose a regular hexagon. The air-permeable rotary shaft 11 is driven to rotate in the first rotation direction. Taking the orientation of the polygon rotary cylinder in the use state as a reference, specifically with Figure 4Taking the shown orientation as a reference, the aforementioned first rotation direction is clockwise. The air passage 111 on the tape-attaching side is the air passage 111 corresponding to the lower side of the regular hexagon, and the air passages 111 on the tape-pulling side are the air passages 111 corresponding to the three sides of the regular hexagon that are on the upstream side of the first rotation direction and are successively adjacent to the air passage 111 on the tape-attaching side (that is, the air passages 111 corresponding to the right region of the ventilation rotation axis 11 shown in the figure). Along the first rotation direction, the three air passages 111 on the tape-pulling side are the first air passage, the second air passage, and the third air passage respectively. The tape-pulling adsorption control air chamber 21 has at least two. One of the tape-pulling adsorption control air chambers 21 is controllably communicated with the air passage 111 corresponding to the first air passage, and the remaining tape-pulling adsorption control air chambers 21 are controllably communicated with the air passages 111 corresponding to the second air passage and the third air passage respectively. For specific reference, see Figure 4 As shown, the aforementioned first air passage is the air passage corresponding to the tape-pulling adsorption control air chamber 21 in the upper position in the figure, while the second air passage and the second air passage correspond to the air passages corresponding to the two tape-pulling adsorption control air chambers 21 in the right region.

[0032] In this technical solution, taking Figure 3 the shown orientation as a reference, since there is no adsorption requirement for the tape at the left position of the ventilation rotation axis 11, the corresponding control air chambers are not provided in the two tape adsorption assemblies 12 on the left side of the ventilation rotation axis 11, thus simplifying the number of air chambers arranged in the fixed ring 2 and further simplifying the air path design.

[0033] For specific reference, see Figure 4 As shown, the number of the tape-pulling adsorption control air chambers 21 is three, and the three tape-pulling adsorption control air chambers 21 are controllably communicated with the air passages 111 corresponding to the first air passage to the third air passage one by one. Specifically, during the tape-pulling process, it is preferably to control the cut-off of the negative pressure of the tape-pulling adsorption control air chamber 21 corresponding to the first air passage to prevent the phenomenon that the air passage adsorbs the tape and causes its deviation.

[0034] In some embodiments, each of the tape-pulling adsorption control air chambers 21 and the tape placement control air chamber 22 is provided with an air extraction port 23 that is independently controllably communicated with the vacuum suction device. The air extraction ports 23 are arranged in pairs on the opposite sides of the regular hexagon, making the structural arrangement at the fixed ring 2 more reasonable.

[0035] In some embodiments, the diameter of the second end port of each air passage 111 is greater than the minimum distance between two adjacent tape-pulling adsorption control air chambers 21 and greater than the minimum distance between the adjacent tape-pulling adsorption control air chamber 21 and the tape placement control air chamber 22, so as to ensure that the negative pressure and the corresponding air chamber are always in a communicated state during the rotation of the polygonal rotating cylinder.

[0036] The first-end port of each of the airways 111 communicates with the correspondingly-positioned negative-pressure adsorption chambers 121 via sliding connection sleeves 112, which can ensure that when each tape adsorption assembly 12 slides and switches positions along the radial direction of the polygonal rotating cylinder, the corresponding negative-pressure adsorption chambers 121 remain in communication with the corresponding airways 111.

[0037] In some embodiments, the tape adsorption assembly 12 includes a connecting plate 122 slidably connected to the ventilation rotating shaft 11 and an adsorption plate 123 detachably connected to the side of the connecting plate 122 away from the ventilation rotating shaft 11. A negative-pressure adsorption chamber 121 is formed between the adsorption plate 123 and the connecting plate 122, and the adsorption plate 123 has a plurality of first adsorption holes (not labeled in the figure) communicating with the negative-pressure adsorption chamber 121.

[0038] In this technical solution, the adsorption plate 123 and the connecting plate 122 are detachably connected, so that the adsorption plate 123 with a matching specification can be replaced according to the specific length requirements of tape cutting and pasting, improving the versatility of the polygonal rotating tape pasting mechanism.

[0039] As a preferred embodiment, the side of the adsorption plate 123 away from the connecting plate 122 has an anti-sticking layer 124, and the anti-sticking layer 124 has second adsorption holes (not labeled in the figure) communicating with the first adsorption holes, which can prevent the tape from sticking to the adsorption plate 123 and ensure the smooth placement of the tape.

[0040] In some embodiments, the polygonal rotating tape pasting mechanism further includes a tape cutting assembly 3. The tape cutting assembly 3 includes a cutter 31 and a heating structure capable of heating the cutter 31. The cutter 31 can perform hot cutting on the tape between the tape adsorption assembly 12 on the tape pulling side and the tape adsorption assembly 12 on the tape pasting side. The tape is cut off through the hot cutting action, reducing the pulling force on the tape and being beneficial to preventing the tape from being misaligned due to excessive acting force. It can be understood that the aforementioned tape cutting assembly 3 further includes a driving device for driving the reciprocating movement of the cutter 31, and this driving device can be, for example, a slide table assembly.

[0041] It can be understood that the polygon rotary tape attaching mechanism further includes a frame 100, a bracket 200, a rotary driving device 101 assembled on the bracket 200, and a lifting driving device 102 assembled on the frame 100. The bracket 200 is slidably connected to the frame 100 in a lifting manner. The supporting end of the ventilation rotary shaft 11 is pivotally connected to the bracket 200. The rotary driving device 101 is drivingly connected to the driving end of the ventilation rotary shaft 11. The lifting driving device 102 is used to drive the bracket 200 to lift or lower to ensure that the polygon rotating cylinder can approach or move away from the battery cell below, thereby facilitating placing the tape on the adsorption plate at the bottom side position of the polygon rotating cylinder on the target area on the top surface of the battery cell. The aforementioned tape cutting assembly 3 is specifically assembled on the bracket 200, that is, the aforementioned lifting driving device 102 can also drive the synchronous lifting of the tape cutting assembly 3. The aforementioned rotary driving device 101 includes a rotary motor and a transmission belt that is drivingly connected between the output rotating shaft of the rotary motor and the driving end of the aforementioned ventilation rotary shaft 11. Specifically, a vertically arranged guide rail assembly is provided between the bracket 200 and the frame 100 to ensure the reliable and stable lifting of the bracket 200 relative to the frame 100.

[0042] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above-mentioned advantageous ways can be freely combined and superimposed.

[0043] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
