Description

Technical Field

[0001] This utility model relates to the field of battery production technology, specifically a multi-axis linear motion module. Background Technology

[0002] With the rapid development of the new energy industry, lithium batteries, as core energy storage components, place higher demands on the precision, efficiency, and integration of automated equipment in their manufacturing processes. In the lithium battery stacking process, positive electrode sheets, negative electrode sheets, and separators are alternately stacked to form a cell structure. This process places extremely high demands on the positioning accuracy, response speed, and motion freedom control of mechanical actuators, typically requiring multi-axis coordination and high dynamic response precision motion control.

[0003] In existing technologies, laminating equipment generally employs a slide structure driven by a servo motor in conjunction with a ball screw or synchronous belt, achieving linear motion through guide rails. However, this traditional driving method suffers from problems such as long transmission chains, mechanical backlash, reverse backlash, and elastic deformation, affecting positioning accuracy and dynamic response performance. Furthermore, in applications requiring multi-degree-of-freedom motion (such as combined lifting and translation movements), multiple independent linear modules are typically stacked, resulting in complex equipment structures, large size, and difficult maintenance, which is detrimental to production line space optimization and high-cycle production requirements. Therefore, this utility model proposes a multi-axis linear motion module. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 As shown, this utility model provides a technical solution: a multi-axis linear motion module, including a base 1, a fixed upright plate 2 fixedly connected to the top of the base 1, a linear motor 3 fixedly installed between the fixed upright plates 2, a movable frame 4 fixedly connected to the output end of the linear motor 3, a slider 5 fixedly connected to one side of the movable frame 4, slide rails 6 adapted to the slider 5 fixedly connected to both sides of the fixed upright plate 2, an mounting strip 7 fixedly connected to one side of the movable frame 4, a flat rail 8 fixedly connected to the top of the movable frame 4 and the mounting strip 7, a second linear motor 9 fixedly connected inside the flat rail 8, and a connecting frame 10 fixedly connected to the output end of the second linear motor 9. This slide module can be adjusted for lifting by driving the movable frame 4 with the linear motor 3, and can also be moved horizontally by driving the connecting frame 10 with the second linear motor 9. It is flexible and convenient to use, greatly facilitating the stacking of lithium batteries, effectively improving the performance of the device, and enhancing its practicality.

[0026] Please refer to the following carefully. Figure 2 and Figure 3 Linear motor 3 and linear motor 9 are both double-moving linear motors. The two moving parts of linear motor 3 are located on both sides of the stator track, while the two moving parts of linear motor 9 are located at both ends of the stator track.

[0027] Please refer to the following carefully. Figure 2 There are two movable frames 4, and correspondingly two linear motors 9. Each movable frame 4 has two mounting strips 7 on one side. The two mounting strips 7 are movably mounted on one side of the fixed upright plate 2. A connecting plate 401 that is fixedly connected to the linear motor 3 is fixed on one side of the movable frame 4.

[0028] Please refer to the following carefully. Figure 2A mounting bracket 11 for fixing the linear motor 3 is fixedly connected to the fixed upright plate 2. The fixed upright plate 2 is U-shaped, and the U-shaped structure of the fixed upright plate, along with the mounting bracket 11, reinforces the linear motor 3, thereby improving the overall frame rigidity and torsional resistance. The symmetrical layout of the two movable frames and the two linear motors further balances the load and driving force, reduces vibration caused by off-center loading, and ensures stability under high-speed movement.

[0029] Working principle:

[0030] Vertical lifting motion (Z-axis direction):

[0031] A linear motor 3 is installed between the fixed uprights on the base. This linear motor has a dual-moving-driver structure, with its stator fixed to the inside of the fixed upright and two moving drivers symmetrically arranged on both sides of the stator track. The moving drivers are rigidly connected to the movable frame 4 via a connecting plate 401. When the linear motor is powered on, the two moving drivers synchronously drive the movable frame to reciprocate vertically along the slide rails 6 on both sides of the fixed upright. The slider 5 and the slide rails 6 form a precision guide pair to ensure the straightness and stability of the movement. This lifting motion can be used to adjust the height of the stacking station or to achieve Z-axis positioning during the material handling process.

[0032] Horizontal translational motion in the X-axis direction:

[0033] A flat rail 8 is fixedly connected to the top of the movable frame 4 and its extended mounting strip 7. A linear motor 9 is integrated inside the flat rail. This motor also employs a dual-mover design, with the movers located at both ends of the stator rail, and the output end connected to a connecting frame 10. When the linear motor 9 is energized, it drives the connecting frame to move horizontally in a straight line along the flat rail. Because the flat rail rises and falls with the movable frame as a whole, the connecting frame can perform translational movements at different height levels, achieving precise trajectory control of a two-dimensional spatial path.

[0034] By independently controlling linear motor 3 and linear motor 9, independent or synchronous lifting and translation movements can be achieved. For example, during the lithium battery stacking process, the movable frame can first raise the connecting frame to the material picking height, and linear motor 9 drives the connecting frame to move to the material picking position; then the movable frame lowers to pick up the material, and then raises it again and is delivered to the stacking station by linear motor 9 to complete the material unloading. The entire process is coordinated by the control system to achieve high-speed, high-precision automated stacking operation.
