[0003] Especially in scenarios involving synchronized adjustment of multiple grippers, existing technologies often require complex transmission systems to achieve coordinated adjustment of multiple gripping points. This not only increases equipment manufacturing costs but also causes inconvenience for daily maintenance. Furthermore, when it is necessary to maintain equidistant expansion or contraction of multiple gripping points, the synchronization accuracy and stability of traditional structures still require optimization.

[0038] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.
[0039] First, combine Figures 1-5 The present invention describes a multi-position equidistant cell gripper according to an embodiment of the present invention, which is used to realize the equidistant displacement of multiple cell grippers and has a wide range of applications.
[0040] like Figures 1-5 As shown, the multi-position equidistant displacement battery cell gripper of this utility model embodiment includes: a fixed base 1, a push plate 2, a drive mechanism 3, and at least three clamping mechanisms 4; the fixed base 1 provides an installation reference for all other components, and a connecting flange 5 is fixed on the fixed base 1 for connecting external moving mechanisms, such as a robotic arm.
[0041] Specifically, such as Figures 1-5As shown, in this embodiment, the push plate 2 is slidably connected to the fixed base 1 via the first guide mechanism 6, which limits the push plate 2 to move only in the first direction. The drive mechanism 3 is mounted on the fixed base 1, and its output end is connected to the push plate 2. The drive mechanism 3 drives the push plate 2 to reciprocate along the first direction. At least three clamping mechanisms 4 are slidably connected to the fixed base 1 via the second guide mechanism 7 to move along the second direction. The second guide mechanism 7 limits the clamping mechanisms 4 to move only in the second direction. The first and second directions are perpendicular to each other. The push plate 2 has guide holes 21 corresponding to the number of clamping mechanisms 4. The inclination angle and length of adjacent guide holes 21 are different, and each guide hole 21 cooperates with the rolling element 41 on the corresponding clamping mechanism 4. When the drive mechanism 3 drives the push plate 2 to move along the first direction, through the cooperation of the guide holes 21 and the rolling element 41, all the clamping mechanisms 4 are driven to move synchronously along the second direction. After the movement, the spacing between all the clamping mechanisms 4 is equal. The drive mechanism 3 provides the power for the push plate 2 to move. Only one power source is needed to realize the collaborative work of multiple grippers, thereby improving efficiency. In this embodiment, the guide hole 21 is an oblong hole.
[0042] like Figure 1 As shown, in this embodiment, there are five guide holes 21 and clamping mechanisms 4. The first direction is vertical and the second direction is horizontal. The guide hole 21C in the middle is set in the vertical direction, and the guide holes 21B and D on both sides are symmetrically set about C. The guide holes A and E are symmetrically set about C. By setting waist-shaped holes with different inclination angles and lengths on the push plate 2, the different moving distances of each clamping mechanism 4 can be changed individually. When the push plate 2 moves in the vertical direction, the horizontal displacement of the clamping mechanism 4 corresponding to the guide hole 21C is 0. The horizontal displacement of the clamping mechanisms 4 corresponding to the guide holes 21A and E is twice that of the clamping mechanisms 4 corresponding to the guide holes 21B and D. After the displacement is achieved, the spacing of each clamping mechanism 4 remains consistent. Multiple mechanisms can be individually and equidistantly displaced by a single power source.
[0043] Specifically, such as Figures 1-5 As shown, in this embodiment, the drive mechanism 3 includes: a mounting frame 31, a drive motor 32, a transmission assembly, and a lead screw 33; the mounting frame 31 is fixed on the fixed base 1; the drive motor 32 and the transmission assembly are mounted on the mounting frame 31; the drive motor 32 is connected to the transmission assembly, and the two ends of the lead screw 33 are respectively connected to the transmission assembly and the push plate 2, converting the rotational motion of the motor 32 into the linear motion of the push plate 2; the drive motor 32 drives the lead screw 33 to rotate through the transmission assembly, thereby moving the push plate 2 vertically. Compared with a cylinder, the drive motor 32, transmission assembly, and lead screw 33 achieve more precise power control and output, making them suitable for battery cell gripping scenarios with strict position requirements.
[0044] Furthermore, such as Figures 1-5As shown, in this embodiment, the transmission assembly includes: a driving wheel 34, a driven wheel 34, and a timing belt 35; the driving wheel and driven wheel 34 are rotatably mounted on the mounting bracket 31; the driving wheel is connected to the output end of the drive motor 32, the driven wheel 34 is connected to the lead screw 33, and the timing belt 35 is sleeved on the driving wheel and driven wheel 34; the drive motor 32 drives the driving wheel to rotate, and drives the driven wheel 34 and the lead screw 33 to rotate through the timing belt 35. The transmission torque and speed can be changed by adjusting the size of the driving wheel and driven wheel 34; the overall structure is lighter and more compact, easy to install, low in cost, and its position can be flexibly adjusted to match the spatial layout of different equipment.
[0045] Specifically, such as Figures 1-5 As shown, in this embodiment, the clamping mechanism 4 includes a battery cell gripper 42 and a rolling element 41. The battery cell gripper 42 is slidably connected to the fixed base 1 via a second guide mechanism 7. The rolling element 41 is connected to the battery cell gripper 42 and is disposed within the guide hole 21, rollingly engaging with the inner wall of the guide hole 21. In this embodiment, the rolling element 41 is a rolling bearing, which rolls with the inner wall of the guide hole 21, suitable for long-term high-load operation and reducing wear.
[0046] Specifically, such as Figures 1-5 As shown, in this embodiment, the first guiding mechanism 6 includes: a pair of first guide rails 61 and a pair of slider brackets 62; the pair of first guide rails 61 are respectively fixed to both ends of the push plate 2; the pair of slider brackets 62 are respectively fixed to both ends of the fixed base 1, and the pair of slider brackets 62 are slidably connected to the pair of first guide rails 61. The number of first guide rails 61 and slider brackets 62 are correspondingly set, with at least two provided to ensure stability. The second guiding mechanism 7 includes: a second guide rail 71 and at least three sliders 72; the second guide rail 71 is fixed to the fixed base 1; the at least three sliders 72 are slidably disposed on the second guide rail 71 and are respectively connected to at least three clamping mechanisms 4 one-to-one. The push plate 2 is limited to move along a first direction by the first guide rail 61, and the clamping mechanism 4 is limited to move along a second direction by the second guide rail 71.
[0047] Working principle: Servo motor 32 drives the active wheel to rotate, which in turn drives the synchronous belt 35 to move. The driven wheel 34 is driven to rotate by the synchronous belt 35 and transmits power to the lead screw 33. The lead screw 33 converts the rotational motion into linear motion, which drives the push plate 2 to move vertically. The oblong hole in the push plate 2 and the rolling bearing of the clamping mechanism 4 are in rolling engagement. Under the limit of the second guide mechanism 7, the horizontal movement of the clamping mechanism 4 is realized. Since the inclination angle and length of each oblong hole are different, the final spacing is guaranteed to be the same. Each clamping mechanism 4 achieves independent pitch change without affecting each other. In the event of power failure or gas failure, servo motor 32 is equipped with a brake function, which will not cause the position of the battery cell gripper 42 to change.
[0048] Above, refer to Figures 1-5This invention describes a multi-position equidistant cell gripper according to an embodiment of the present invention. Through the guide hole on the push plate and the cooperation of a rolling bearing, a single drive is transformed into synchronous equidistant movement of multiple grippers. Rolling friction makes the movement smooth and durable, suitable for high-speed operation; the motor screw drive ensures accuracy, combining stability and low cost advantages, making it suitable for the automated gripping needs of power battery production lines.
