If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0035] As mentioned in the background technology, in the related technology, the contact area between the battery silicon wafer transmission device and the battery silicon wafer is small, which causes the battery silicon wafer to slip easily during transportation, which not only affects the production efficiency but also poses the risk of damaging the battery silicon wafer.

[0036] Based on this, an embodiment of the present application provides a transmission device that can solve the above problem. The transmission device provided by an embodiment of the present application will be described in detail below in conjunction with the accompanying drawings.

[0037] See also Figure 1 and Figure 4 As shown, a transmission device provided in an embodiment of the present application includes a base 110, an adjustment unit and a transmission unit; wherein the adjustment unit includes an adjustment drive 210 and a movable plate 220 connected to the adjustment drive 210, and the movable plate 220 is rotatably connected to the base 110; the adjustment drive 210 is used to drive the movable plate 220 to deflect with the transmission direction as the axis to adjust the angle between the movable plate 220 and the base 110; the transmission unit is arranged on the movable plate 220, and the transmission unit includes a transmission drive 310 and a transmission part 320 connected to the transmission drive 310, and the transmission drive 310 is used to drive the transmission part 320 to move back and forth along the transmission direction, and the transmission part 320 is used to transmit the battery silicon wafer 1000. As shown Figure 1 As shown, the transmission direction is the X direction in the figure.

[0038] The above-mentioned transmission device drives the movable plate 220 to deflect through the adjustment unit, thereby changing the angle between the movable plate 220 and the base 110. Since the transmission part 320 is arranged on the movable plate 220, the inclination angle of the plane where the transmission part 320 is located is changed, so that the plane where the transmission part 320 is located can be adjusted according to the warping degree of the battery silicon wafer 1000, so that the battery silicon wafer 1000 and the transmission part 320 have a larger contact area. Figure 2 As shown, when the transmission device is transmitting the horizontal cell silicon wafer 1000, the movable plate 220 is adjusted to be in a horizontal state, that is, the movable plate 220 is parallel to the base 110; the cell silicon wafer 1000 will be warped after the BSG (Back Surface Gridding) process and the PECVD (Plasma-Enhanced Chemical Vapor Deposition) process. Figure 4 As shown, when transmitting the warped cell silicon wafer 1000 that bulges upward, the adjusting driving member 210 drives the movable plate 220 to deflect, so that the inner side of the movable plate 220 (the inner side is the side close to the center of the base 110) tilts upward, so that the contact surface of the transmission part 320 is adapted to the warped surface of the cell silicon wafer 1000; similarly, when transmitting the warped cell silicon wafer 1000 that bulges downward, the adjusting driving member 210 drives the movable plate 220 to deflect, so that the inner side of the movable plate 220 tilts downward, so that the contact surface of the transmission part 320 is adapted to the warped surface of the cell silicon wafer 1000. In this way, the contact area between the movable plate 220 and the cell silicon wafer 1000 can be increased, the slippage of the cell silicon wafer 1000 can be improved, and the risks of blockage and scratches caused by slippage can be reduced, thereby ensuring production efficiency.

[0039] See also Figure 1 As shown, in one embodiment, one end of the movable plate 220 along the first direction is rotatably connected to the base 110, and the other end of the movable plate 220 along the first direction is slidably connected to the base 110. Figure 1 As shown, the first direction is the Y direction in the figure, and the first direction is perpendicular to the transmission direction. For example, in the present embodiment, the inner side of the movable plate 220 is slidably connected to the base 110, and the outer side of the movable plate 220 is rotatably connected to the base 110. It can be understood that in other embodiments, the outer side of the movable plate 220 can also be slidably connected to the base 110, and the inner side of the movable plate 220 can be rotatably connected to the base 110. Since both ends of the movable plate 220 along the first direction are connected to the base 110, the base 110 can play a certain limiting role, thereby increasing the movement reliability of the movable plate 220 during the deflection process, improving the control accuracy of the movable plate 220, and thus improving the adjustment reliability.

[0040] In other embodiments, a pin shaft may be provided in the middle of the movable plate 220, and the movable plate 220 is rotatably connected to the base 110 via the pin shaft, that is, the two ends of the movable plate 220 along the first direction have no connection relationship with the base 110, and the inclination angle of the transmission part 320 can be adjusted by controlling the movable plate 220 to rotate clockwise or counterclockwise.

[0041] See also Figure 1 As shown, in one embodiment, the base 110 is provided with a first fixed frame 120 and a first movable frame 130 distributed along a first direction, one end of the movable plate 220 along the first direction is rotatably connected to the first fixed frame 120, and the other end of the movable plate 220 along the first direction is slidably connected to the first movable frame 130. Specifically, the upper surface of the base 110 is fixedly provided with a first fixed frame 120 and a first movable frame 130 spaced from the first fixed frame 120, and the first fixed frame 120 and the first movable frame 130 can be fixedly connected to the base 110 by fasteners such as screws. The two ends of the movable plate 220 along the first direction are respectively connected to the first fixed frame 120 and the first movable frame 130. Through this arrangement, the movable plate 220 is suspended relative to the base 110, so the movable plate 220 has a larger range of movement space, reducing the possibility of interference between the movable plate 220 and the base 110 during adjustment, and the movable plate 220 can be made into a thin plate structure.

[0042] It can be understood that the first fixed frame 120 and the first movable frame 130 are provided at both ends of the base 110 along the transmission direction to fix the two ends of the movable plate 220 along the transmission direction and improve the adjustment reliability of the movable plate 220 .

[0043] See also Figure 1 As shown, in one embodiment, one of the movable plate 220 and the first fixed frame 120 is provided with a first rotating shaft 222, and the other of the movable plate 220 and the first fixed frame 120 is provided with a first connecting hole 121, and the first rotating shaft 222 is plugged into and matched with the first connecting hole 121.

[0044] Specifically, in this embodiment, the first rotating shaft 222 is also provided at both ends of the movable plate 220 along the transmission direction, and the first fixed frame 120 is provided with a first connecting hole 121, and the first rotating shaft 222 is plugged and matched with the first connecting hole 121. In this way, the movable plate 220 is rotatably connected with the base 110, so that it can deflect relative to the base 110 with the first rotating shaft 222 as a fulcrum. Among them, the outer diameter of the first rotating shaft 222 is adapted to the aperture of the first connecting hole 121, and the movable plate 220 will not shake arbitrarily during the deflection process through the restriction of the hole wall of the first connecting hole 121, thereby improving the accuracy of the movement. In other embodiments, the first rotating shaft 222 may be provided on the first fixed frame 120, and the movable plate 220 may be provided with a first connecting hole 121. Through the cooperation of the first rotating shaft 222 and the first connecting hole 121, the movable plate 220 rotates relative to the base 110 around the first rotating shaft 222.

[0045] Furthermore, if Figure 1 As shown, one of the first movable frame 130 and the movable plate 220 is configured with a first slide groove 131, and the other of the first movable frame 130 and the movable plate 220 is movably connected to the groove wall of the first slide groove 131. Specifically in this embodiment, the first movable frame 130 is configured with a first slide groove 131, and the movable plate 220 is movably connected to the groove wall of the first slide groove 131. The movable plate 220 is respectively provided with a first connecting shaft 221 at both ends along the transmission direction, and the first connecting shaft 221 is penetrated through the first slide groove 131 and slidably connected to the groove wall of the first slide groove 131. Through the provision of the first slide groove 131, the deflection trajectory of the movable plate 220 can be limited, and through the first connecting shaft 221 abutting against the extended end of the first slide groove 131, the deflection angle of the movable plate 220 can be limited, and the adjustment reliability of the movable plate 220 can be further improved. In other embodiments, the first movable frame can also be provided with a first connecting shaft, and the movable plate can be provided with a first slide groove.

[0046] See also Figure 1 As shown, in one embodiment, the first slide groove 131 is in an arc shape, the center point of which is the axis of the first rotating shaft 222, and the first slide groove 131 is symmetrical along the horizontal plane, so that the upward deflection angle and the downward deflection angle of the movable plate 220 are consistent.

[0047] See also Figure 1As shown, in one embodiment, the adjustment unit further includes a first limiting portion 230 connected to the first connecting shaft 221, and the first limiting portion 230 is used to abut against the first movable frame 130 to limit the movement of the first connecting shaft 221. Specifically in this embodiment, the first limiting portion 230 is threadedly connected to one end of the first connecting shaft 221 away from the movable plate 220. When the angle of the movable plate 220 needs to be adjusted, the first limiting portion 230 is loosened, that is, the first limiting portion 230 and the first movable frame 130 have a gap along the transmission direction, so that it is more convenient to rotate the movable plate 220; when the tilt angle of the movable plate 220 is adjusted, the first limiting portion 230 is tightened to abut against the first movable frame 130, which can not only rely on the adjustment drive 210 to achieve the locking of the movable plate 220, but also can further lock the movable plate 220 through the first limiting portion 230, so as to ensure the reliability of the movable plate 220 at the current tilt angle, thereby ensuring the reliability of the transmission unit supporting the battery silicon wafer 1000. At the same time, the provision of the first limiting portion 230 can also prevent the first connecting shaft 221 from being separated from the first sliding groove 131, thereby improving the transmission stability of the transmission device.

[0048] In other embodiments, the first fixed frame 120 and the first movable frame 130 may not be provided, the thickness of the movable plate 220 along the Z direction is relatively large, and the first sliding groove 131 and the first connecting hole 121 are provided on the movable plate 220 for connecting with the movable plate 220 to achieve angle adjustment of the movable plate 220.

[0049] Furthermore, if Figure 1 As shown, an avoidance hole 111 is provided in the area of ​​the base 110 corresponding to the movable plate 220. On the one hand, the avoidance hole 111 can allow part of the adjustment unit to pass through so that the adjustment unit is connected to the movable plate 220; on the other hand, the movable plate 220 can also be avoided to provide a larger activity space for the movable plate 220, reducing the risk of interference between the two, so that the movable plate 220 has a larger adjustment angle, adapts to battery cells with different degrees of warping, and improves the adaptability of the transmission device.

[0050] See also Figure 1 and Figure 3As shown, in one embodiment, the adjustment unit includes an adjustment joint 240, one end of which is connected to the adjustment drive 210, and the other end is rotatably connected to the movable plate 220; the adjustment drive 210 is used to drive the adjustment joint 240 to move in the vertical direction to drive the movable plate 220 to deflect. The vertical direction is the Z direction in the figure. Specifically in this embodiment, a first connecting portion 223 is provided on the bottom surface of the movable plate 220, the lower end of the adjustment joint 240 is connected to the adjustment drive 210, and the upper end of the adjustment joint 240 is rotatably connected to the first connecting portion 223. Since the motion trajectory of the movable plate 220 is an arc shape, and the motion direction of the adjustment drive 210 is a vertical direction, the first connecting portion 223 is rotatably connected to the adjustment joint 240, so as to adapt the deflection direction of the movable plate 220, and realize the deflection of the movable plate 220 relative to the base 110.

[0051] See also Figure 1 and Figure 3 As shown, in one embodiment, the movable plate 220 and the transmission unit each include two, each movable plate 220 is provided with one transmission unit, and the distribution direction of the two movable plates 220 is perpendicular to the transmission direction. By providing two groups of transmission units, the support points and support area for the battery silicon wafer 1000 are increased, and the transmission stability of the battery silicon wafer 1000 is improved.

[0052] See also Figure 1 and Figure 3 As shown, in one embodiment, the adjustment joint 240 includes a main body 241 and two adjustment connection parts 242 respectively connected to both sides of the main body 241, and each of the adjustment connection parts 242 is rotationally connected to one of the movable plates 220 in a one-to-one correspondence. The main body 241 and the two adjustment connection parts 242 make the adjustment joint 240 present a V-shaped structure. In this way, only one adjustment joint 240 and one adjustment drive member 210 are required to simultaneously realize the angle adjustment of two groups of movable plates 220. When the adjustment drive member 210 drives the adjustment joint 240 to move upward, the inner sides of the two movable plates 220 are simultaneously deflected upward, so that the transmission part 320 presents as shown in FIG. Figure 4 When the adjustment drive member 210 drives the adjustment joint 240 to move downward, the inner sides of the two movable plates 220 are simultaneously deflected downward, so that the transmission portion 320 presents a Figure 5 Specifically in this example, the adjustment drive member 210 may be a screw motor, and the main body 241 is threadedly connected to the output screw of the screw motor, so that the main body 241 is driven to move in the vertical direction through the output screw.

[0053] In other embodiments, two adjustment joints 240 and two adjustment driving members 210 may also be provided, and each adjustment driving member 210 drives a corresponding movable plate 220 .

[0054] See also Figure 1 and Figure 2 As shown, in one embodiment, the transmission part 320 includes a transmission belt 321; the transmission unit includes a plurality of transmission wheels 330 connected to the transmission belt 321, one of which is connected to the transmission drive 310 to drive the transmission belt 321 to move back and forth. Specifically in this embodiment, the transmission wheels 330 include three, and the three transmission wheels 330 are distributed in a T shape and are frictionally transmitted with the transmission belt 321. The transmission wheel 330 located at the bottom is connected to the transmission drive 310, for example, the two are connected through a coupling to realize the input of rotational power, wherein two transmission wheels 330 are arranged along the transmission direction, and the transmission drive 310 drives the transmission wheels 330 to rotate, and then the friction force is used to realize the reciprocating movement of the transmission belt 321 to transport the battery silicon wafer 1000. The transmission drive 310 can be a motor.

[0055] See also Figure 1 and Figure 2 As shown, in one embodiment, the transmission unit further includes at least one tensioning wheel 340, and the tensioning wheel 340 and the transmission belt 321 are frictionally driven. The tensioning wheel 340 keeps the transmission belt 321 in proper tension, which can prevent the transmission belt 321 from slipping due to looseness during operation, and can also reduce the wear of the transmission belt 321 and extend its service life. At the same time, the tensioning wheel 340 can also play a guiding role, ensuring that the transmission belt 321 moves along a predetermined path, preventing the transmission belt 321 from deviating from the predetermined path during operation, thereby maintaining stable operation of the system.

[0056] Understandably, if Figure 1 As shown, the movable plate 220 is provided with a motor bracket 251 for fixing the transmission drive member 310. Further, the movable plate 220 is also provided with a track bracket 252 for fixing a plurality of tension wheels 340 and a plurality of transmission wheels 330.

[0057] In the above transmission device, the adjusting driving member 210 drives the two movable plates 220 to deflect synchronously by adjusting the joint 240, thereby changing the angle between the movable plate 220 and the base 110, and further changing the inclination angle of the plane where the transmission part 320 is located. Figure 2 As shown, when the transmission unit 320 transmits the horizontal silicon wafer 1000, the movable plate 220 is adjusted to be in a horizontal state, that is, the movable plate 220 is parallel to the base 110; Figure 4As shown, when transmitting the warped cell silicon wafer 1000 that bulges upward, the adjusting driving member 210 drives the movable plate 220 to deflect, so that the inner side of the movable plate 220 tilts upward, so that the contact surface of the transmission part 320 matches the warped surface of the cell silicon wafer 1000; similarly, when transmitting the warped cell silicon wafer 1000 that bulges downward, the adjusting driving member 210 drives the movable plate 220 to deflect, so that the inner side of the movable plate 220 tilts downward, so that the contact surface of the transmission part 320 matches the warped surface of the cell silicon wafer 1000. In this way, the contact area between the movable plate 220 and the cell silicon wafer 1000 can be increased, the slippage of the cell silicon wafer 1000 can be improved, and the risks of blockage and scratches caused by slippage can be reduced, thereby ensuring production efficiency.
