Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application.

[0046] The sheet transfer device currently used transports the sheets to be pasted by translation or horizontal transportation. During the translation or horizontal transportation of the sheets to be pasted by the sheet transfer device, it is necessary to cooperate with other mechanisms to complete operations such as peeling off the glue and straightening the sheets to be pasted. This sheet transfer method requires the sheets with adhesive to be transferred between various mechanisms, resulting in a long conveying path, a complex structure, and a large space occupied.

[0048] Based on this, the present application provides a sheet transfer device, which, through at least two sheet fixing components arranged on the rotating frame, can complete the sheet picking action at the sheet picking station after the rotating frame rotates a certain angle. After the rotating frame rotates a certain angle again, before the previous sheet fixing component moves to the patch station, the other sheet fixing component moves to the sheet picking station and completes the sheet picking action, thereby realizing the cyclic action of at least two sheet fixing components, that is, when the rotating frame rotates one circle, at least two sheet patch actions can be completed, thereby significantly improving the patch efficiency of the entire sheet transfer device; moreover, completing the sheet picking and patch actions through the rotation action of the rotating frame can effectively shorten the sheet conveying path, and at the same time reduce the space occupied by the sheet transfer device.

[0049] The present application will be described in detail below through specific embodiments.

[0050] Reference Figures 1 to 9As shown, this embodiment provides a sheet transfer device, which includes: a fixed frame 1, a rotating frame 2, a rotating drive member 3 and at least two sheet fixing components 4 arranged circumferentially on the rotating frame 2; the rotating frame 2 is rotatably set on the fixed frame 1 through a first rotating shaft, and the driving end of the rotating drive member 3 is transmission-connected to the rotating frame 2, and the rotating drive member 3 is used to drive the rotating frame 2 to rotate so as to drive all the sheet fixing components 4 to rotate around the first rotating shaft; two adjacent sheet fixing components 4 are spaced at a set angle, and when the rotating frame 2 is set at an angle around the first rotating shaft, at least two sheet fixing components 4 respectively correspond to at least two setting stations; wherein, the setting stations can be four, and when the setting stations are set When there are four fixed stations, the four set stations can be spaced 90 degrees apart from each other. When there are three set stations, they can be spaced 120 degrees apart from each other. The four set stations can be respectively a sheet-taking station 91, a film-tearing station 92, a regularization station 93 and a chip-placing station 94. The four stations can be arranged in sequence along the rotation direction (clockwise or counterclockwise) of the sheet fixing component 4, so that the sheet fixing component 4 first runs to the sheet-taking station 91 and connects and fixes a sheet, then passes through the film-tearing station 92 to tear off the protective film on the sheet, and then passes through the regularization station 93 before reaching the chip-placing station 94 to adjust the position and posture of the sheet, and finally reaches the chip-placing station 94 to attach and fix it to the predetermined surface of the battery cell. Of course, according to the actual working conditions, the number of set stations can be increased or decreased accordingly.

[0051] The sheet transfer device provided in this embodiment can, through at least two sheet fixing components 4 arranged on the rotating frame 2, complete the sheet picking action at the sheet picking station 91 after the rotating frame 2 rotates a certain angle, and before the first sheet fixing component 4 moves to the sheet patching station 94, the second sheet fixing component 4 moves to the sheet picking station 91 and completes the sheet picking action after the rotating frame 2 rotates a certain angle again, thereby realizing the cyclic action of at least two sheet fixing components 4, that is, when the rotating frame 2 rotates one circle, at least two sheet patching actions can be completed, thereby significantly improving the patching efficiency of the entire sheet transfer device; moreover, the sheet picking and patching actions are completed through the rotation action of the rotating frame 2, which can effectively shorten the sheet conveying path and reduce the space occupied by the sheet transfer device.

[0052] Among them, the rotating driving member 3 can be a motor or a rotary cylinder or other structure. The output end of the rotating driving member 3 can be directly connected to the rotating frame 2 through a coaxial transmission, or the output end of the rotating driving member 3 can be connected to the rotating frame 2 through a gear set. The specific selection can be made according to the specifications of the rotating driving member 3.

[0053] Continue to refer to Figure 7As shown, specifically, the sheet fixing assembly 4 includes a connecting frame 41 and a fixing part 42 installed on the connecting frame 41. The connecting frame 41 is installed on the rotating frame 2, and the fixing part 42 is used to fix or release a sheet; wherein, the fixing part 42 can fix the sheet by clamping, adsorption, bonding, etc., to ensure that the sheet can always maintain relative stability between itself and the fixing part 42 during the process of following the rotation of the rotating frame 2. It should be noted that the fixing part 42 cannot interfere with the side of the sheet on which the film is applied when fixing the sheet.

[0054] In some embodiments, the connecting frame 41 is set on the rotating frame 2 for radial sliding along the first rotating shaft, and / or the fixing member 42 is set on the connecting frame 41 for radial sliding along the first rotating shaft; that is, through the sliding of the connecting frame 41 and / or the fixing member 42, the fixing member 42 can be extended in the direction away from the axis of the first rotating shaft to take the film and the fixing member 42 can drive the sheet body to extend in the direction away from the axis of the first rotating shaft to complete the action of tearing the film and regularizing the sheet body.

[0055] Furthermore, the fixing part 42 is a suction cup, which is connected to the negative pressure device through an air pipe. A slip ring 5 is provided on the fixing frame 1, and the air pipe is connected to the negative pressure device through the slip ring 5; specifically, the air pipe is connected to the rotor of the slip ring 5, and the negative pressure device is connected to the stator of the slip ring 5, thereby ensuring that when the fixing part 42 drives the air pipe to rotate together, the air pipe is not easily entangled and knotted, and at the same time, the connection relationship between each fixing part 42 and the negative pressure device is maintained.

[0056] Continue to refer to Figure 1 and Figure 6 As shown, the sheet transfer device also includes a telescopic driving member 6, the fixed end of the telescopic driving member 6 is fixedly connected to the fixed frame 1, and the driving end of the telescopic driving member 6 is connected to the connecting frame 41 or the fixed frame 1. The telescopic driving member 6 is used to drive the connecting frame 41 or the fixed member 42 to slide radially along the first rotating shaft.

[0057] Specifically, the telescopic drive member 6 can be a linear motor, an electric cylinder, a pneumatic cylinder or other structures. Through the setting of the telescopic drive member 6, it can also actively drive the corresponding connecting frame 41 or the fixing member 42 to slide. Specifically, the telescopic drive member 6 can be set one-to-one with the sheet fixing component 4. The telescopic drive member 6 can also be set only at one or two or more set stations, so as to ensure that the sheet fixing component 4 can slide radially along the first rotating shaft when it is transported to the set station, so as to realize sheet taking, patching, film tearing or regularization.

[0058] In some embodiments, at least two setting stations include a sheet-taking station 91 and a sheet-attaching station 94, and the number of telescopic driving members 6 is two groups. The two groups of telescopic driving members 6 are correspondingly arranged at the sheet-taking station 91 and the sheet-attaching station 94, and are respectively used to drive the fixing member 42 or the connecting frame 41 located at the sheet-taking station 91 to slide radially along the first rotating shaft to control the fixing member 42 to take the sheet, and to drive the fixing member 42 or the connecting frame 41 located at the sheet-attaching station 94 to slide radially along the first rotating shaft to control the fixing member 42 to attach the sheet to the predetermined surface of the battery cell.

[0059] Furthermore, the sheet transfer device also includes a fixed connecting frame 7, and the fixed end of the telescopic drive member 6 is fixedly mounted on the fixed frame 1 through the fixed connecting frame 7; wherein, the telescopic drive member 6 can be set only at the sheet taking station 91 and the patch station 94, that is, when the sheet is transported to the film tearing station 92 and the regularization station 93, there is no need to push the sheet along the radial direction of the first rotating shaft; the two telescopic drive members 6 can be fixedly mounted on the same fixed connecting frame 7. Through the setting of the fixed connecting frame 7, the stability of the two telescopic drive members 6 can be further improved, and the accuracy of the two when working can be improved.

[0060] In some embodiments, a ring track 81 is provided on the fixing frame 1, and each sheet fixing component 4 is slidably matched with the ring track 81 through a track slider 82; wherein, the ring track 81 is preferably in the shape of a circular ring coaxially arranged with the first rotating shaft, and all sheet fixing components 4 always maintain smooth sliding when sliding on the ring track 81 through the track slider 82; specifically, the track slider 82 can be a fan-shaped slider, at this time the inner wall portion of the track slider 82 slides with the inner wall of the ring track 81, and the outer wall portion of the track slider 82 slides with the outer wall of the ring track 81. The track slider 82 can also be a cylindrical slider, thereby reducing its friction with the ring track 81 and making the sliding smoother.

[0061] Continue to refer to Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 and Figure 9As shown, in some embodiments, a notch is provided on the annular track 81 at at least two setting positions, and the track slider 82 can slide along the notch in the radial direction of the first rotating shaft, that is, when the sheet fixing assembly 4 and the track slider 82 slide to the notch position, they can be driven by the telescopic driving member 6 to detach from the annular track 81 through the notch and move radially along the first rotating shaft, so as to realize that the telescopic driving member 6 drives the connecting frame 41 or the fixing member 42 to move radially of the first rotating shaft at the setting position, and / or, a sliding plate 83 is provided on the fixing frame 1 at at least two setting positions, and the sliding plate 83 is slidably arranged on the fixing frame 1 along the radial direction of the first rotating shaft, and at least part of the annular track 81 is formed on the sliding plate 83, that is, a track groove for the track slider 82 to slide is provided on the sliding plate 83, and the track groove When the telescopic drive member 6 drives the connecting frame 41 or the fixing member 42 to reset, the sliding plate 83 and the track slider 82 are reset under the drive of the telescopic drive member 6, and the track grooves on them are overlapped with the annular track 81 on the fixing frame 1 to form a circular ring structure.

[0062] Furthermore, the sliding plate 83 may have two radial side edges parallel to the first rotating shaft. The sliding plate 83 slides with the fixing frame 1 through the two side plates, thereby improving the stability and reliability of the sliding plate 83 when sliding radially along the first rotating shaft.

[0063] Continue to refer to Figures 1 to 5As shown, the number of sheet fixing components 4 and the number of setting stations are both four, and the interval between every two adjacent sheet fixing components 4 is 90 degrees, and the interval between every two adjacent setting stations is 90 degrees. At this time, the four setting stations can be respectively a sheet taking station 91, a film tearing station 92, a regularization station 93 and a chip mounting station 94. The four stations can be arranged in sequence along the rotation direction of the sheet fixing component 4 (clockwise or counterclockwise), so that the sheet fixing component 4 first runs to the sheet taking station 91, and connects and fixes a sheet, and then passes through the film tearing station 92 for film tearing, and then passes through the regularization station 93 to adjust the position and posture of the sheet before reaching the chip mounting station 94, and finally goes to the chip mounting station 94 to be attached and fixed to the predetermined surface of the battery cell. It should be understood that after the sheet fixing component 4 takes a sheet from the sheet taking station 91, it rotates 90 degrees to the film tearing station 92 for film tearing. At this time, the second sheet fixing component 4 moves to the sheet taking station 91 and starts to take the sheet. The sheet fixing assembly 4 at the film tearing station 92 continues to rotate 90 degrees to the regularization station 93 to adjust the relative position between the sheet and the sheet fixing assembly 4. At this time, the second sheet fixing assembly 4 moves to the film tearing station 92 to tear the film, and the third sheet fixing assembly 4 moves to the sheet taking station 91 and starts to take the sheet. The first sheet fixing assembly 4 continues to rotate 90 degrees to the patch station 94 and attaches the sheet to the predetermined surface of the battery cell. The second sheet fixing assembly 4 rotates to the regularization station 93 to adjust the relative position between the sheet and the sheet fixing assembly 4. The third sheet fixing assembly 4 rotates to the film tearing station 92 to tear the film, and the fourth sheet fixing assembly 4 starts to move to the sheet taking station 91 and starts to take the sheet. The first sheet fixing assembly 4 continues to rotate 90 degrees and returns to the sheet taking station 91 to take the sheet and start the next cycle. The sheet transfer device can simultaneously realize the four sheet fixing assemblies 4 to continuously cycle, thereby improving the film pasting efficiency.

[0064] Continue to refer to Figure 2 As shown, the fixing member 42 has a fixing plane 421 for fixing the sheet, and the fixing plane 421 is perpendicular to the radial direction of the first rotating shaft, wherein two setting stations are arranged in the vertical direction, and the other two setting stations are arranged in the horizontal direction. The uppermost setting station is used to regularize the sheet located on the uppermost fixing plane 421; it should be understood that when the uppermost setting station is the regularizing station 93, the fixing plane 421 is a horizontal plane. After the sheet fixing assembly 4 drives the sheet to move to the regularizing station 93, the fixing of the sheet by the fixing member 42 can be cancelled. Specifically, it can be achieved by releasing the negative pressure in the suction cup on the fixing member 42, or separating the clamping claws, etc. At this time, the sheet can be maintained on the fixing plane 421 under the support of the fixing plane 421, and then regularizing the sheet through the regularizing mechanism will be easier, and can also reduce the external force on the sheet, and reduce the probability of damage to the sheet when regularizing the sheet.
