Description

Technical Field

[0001] This utility model relates to the field of slide module technology, specifically a compact, highly integrated precision slide module. Background Technology

[0002] With the rapid development of the new energy industry, lithium batteries, as core energy storage components, face increasingly stringent requirements for precision, efficiency, and reliability in their manufacturing processes. In lithium battery production, the stacking process is one of the key factors determining cell performance and safety. This process involves alternately stacking positive electrode sheets, negative electrode sheets, and separators to form a "Z"-shaped cell structure. It requires the positioning accuracy of each electrode sheet to reach the micrometer level, and the movement must be high-speed, stable, and vibration-free to ensure interlayer alignment, prevent short circuits, and improve energy density and cycle life.

[0003] Currently, battery stacking equipment generally uses high-precision linear motion modules as the core execution unit for electrode picking, placement, and positioning. Traditional solutions often use ball screws in conjunction with servo motors for drive, which suffers from problems such as transmission backlash, response lag, and frequent maintenance, making it difficult to meet the requirements of stacking processes for high acceleration, high repeatability, and long-term stable operation. In recent years, linear motor drive technology has gradually become the preferred drive method for high-end stacking machines due to its advantages such as contactless operation, zero backlash, fast response, and high precision.

[0004] However, existing linear motor slide modules still face several technical challenges in battery stacking applications: First, although the stacking workshop has a certain level of cleanliness control, there are still contaminants such as metal dust and separator debris generated from electrode cutting. If these enter the module, they can easily cause magnetic pole contamination of the linear motor, guide rail wear, or slider jamming, seriously affecting equipment stability and product yield. Second, the folded dust cover used to achieve long-stroke motion is prone to lateral displacement, uneven folding, or resonance vibration under high-frequency reciprocating motion (typical stacking frequency can reach hundreds of times per minute). This not only affects the appearance but may also cause changes in motion resistance, leading to positioning deviations. Therefore, a compact, highly integrated precision slide module is proposed here. Utility Model Content

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.

[0020] Please see Figures 1-4 As shown, this utility model provides a technical solution: a compact, highly integrated precision slide module, including a fixed base 1, a linear motor stator 2 installed inside the top of the fixed base 1, a linear motor mover 3 provided on the linear motor stator 2, a worktable 4 connected to the linear motor mover 3, and folding dust covers 5 provided at both ends of the worktable 4, with the end of the folding dust cover 5 away from the worktable 4 fixed to the end plates 6 on both sides of the fixed base 1.

[0021] The fixed base 1 of this utility model has an inner side plate 8 fixedly connected inside, and an outer side plate 9 fixedly connected to the fixed base 1. An installation space 10 is provided between the inner side plate 8 and the outer side plate 9. A guide rod 11 is fixedly installed inside the installation space 10. A guide hole 12 is opened at the bottom of the folding dust cover 5. The guide rod 11 is inserted into the guide hole 12. The diameter of the guide hole 12 is larger than the diameter of the guide rod 11. By setting the folding dust cover 5, the interior of the linear module can be protected to prevent the workpiece from entering the interior of the linear module. In addition, the guide hole at the bottom of the folding dust cover 5 and the guide rod 11 installed on the fixed base 1 can prevent the folding dust cover 5 from shifting and improve the operating stability of the equipment.

[0022] Please refer to the following carefully. Figure 2 and Figure 3 The top of the inner side plate 8 is fixedly installed with a rail 7, and the bottom of the worktable 4 is fixedly connected with a slider 13 that is compatible with the rail 7. The inside of the fixed seat 1 is also fixedly connected with a guide rod 16. The bottom of the worktable 4 is fixedly connected with a guide block 17. The inside of the guide block 17 is provided with a guide hole 18. The guide rod 16 is compatible with the guide hole 18, and the guide rod 16 can be movably inserted into the inside of the guide hole 18. The bottom of the fixed seat 1 is fixedly connected with a fixed ear 19, and the inside of the fixed ear 19 is provided with a through hole.

[0023] Please refer to the following carefully. Figure 1 and Figure 2 A photoelectric switch light shield 14 is fixedly connected to one side of the bottom of the worktable 4, and a photoelectric switch 15 is fixedly installed on one side of the outer side plate 9. The photoelectric switch light shield at the bottom of the worktable moves with the worktable and cooperates with the photoelectric switch fixed on the outer side plate to detect the extreme position or intermediate positioning point of the worktable, realizing the travel limit and position feedback functions. The fixing ears at the bottom of the fixing base are used to install the entire module to the external base to ensure stable installation.

[0024] Working principle: The compact, highly integrated precision slide module described in this application works based on the synergistic effect of direct linear motor drive and multiple guiding and limiting mechanisms, combined with an innovative folding dust cover guiding structure, to achieve high-precision, high-speed, and high-stability linear reciprocating motion.

[0025] Specifically, a linear motor stator is installed inside the fixed base, and a linear motor mover electromagnetically coupled to it is positioned above the stator. When the control system applies alternating current to the linear motor stator, a traveling wave magnetic field is generated, driving the linear motor mover to move linearly in a predetermined direction. The linear motor mover is rigidly connected to the worktable, thereby driving the worktable to achieve precise displacement.

[0026] The movement guidance of the worktable is ensured by two parts: First, the slider at the bottom of the worktable cooperates with the rail fixed to the top of the inner side plate to form the main load-bearing and guiding structure; Second, the bottom of the worktable is also equipped with a guide block, whose internal guide hole 2 cooperates with the guide rod fixed in the fixed seat to form an auxiliary guide, effectively suppressing deflection and shaking during the movement, and improving the stability of the movement and the positioning accuracy.

[0027] To prevent external contaminants from entering the module, foldable dust covers are installed at both ends of the worktable. One end of the dust cover moves synchronously with the worktable, while the other end is fixed to the end plates on both sides of the mounting base. In particular, the bottom of the foldable dust cover has a guide hole, which fits onto the guide rod on the mounting base (located in the installation space between the inner and outer side plates). The diameter of the guide hole is slightly larger than the diameter of the guide rod, allowing the dust cover to slide smoothly along the guide rod when the worktable extends and retracts, thereby limiting its lateral displacement and preventing twisting, displacement, or jamming during the folding process.
