Description

Technical Field

[0001] The utility model relates to the field of lithium battery production and testing technology, specifically to a guided transport platform for lithium battery CT testing. Background Technology

[0002] With the widespread application of lithium batteries in new energy vehicles, energy storage systems and consumer electronics, the requirements for their internal quality and safety testing are increasing. Computed tomography (CT) testing technology, as a non-destructive and high-precision method for detecting internal defects, is gradually being promoted in lithium battery production. CT testing can clearly present key information such as the alignment of the internal electrodes and separators, the welding quality of the tabs, and the presence of metal foreign objects, which plays an important role in improving battery quality and safety.

[0003] In existing CT inspection processes, lithium batteries to be inspected, or the trays carrying the batteries, typically need to be transferred from the loading station to the CT scanning station and removed after scanning. Common transfer methods include belt conveyors, chain conveyors, or robotic grippers. While these methods achieve material transport, they generally suffer from the following problems: 1. Reliance on external power: Belts, chains, or robots all require continuous electric drive, have complex structures, high energy consumption, and loud operating noise; 2. Collision risk: When using robots or push rods for transfer, improper control may result in rigid collisions with batteries or trays, which may cause damage to the battery's appearance or minor damage to its internal structure. The risk is especially high for pouch batteries or assembled modules. 3. Poor flexibility and high maintenance costs: Dedicated conveyor lines are usually designed for specific battery specifications. When products are changed, adjustments are difficult, and the transmission components need to be maintained or replaced regularly after wear, which increases downtime and operating costs.

[0004] Therefore, we propose a transfer device that is simple in structure and operates smoothly. Summary of the Invention

[0005] The purpose of this invention is to provide a guided transport platform for lithium battery CT detection, which solves the problems of traditional devices with complex structures or unstable transportation.

[0006] This utility model is achieved through the following technical solution: A guided transport platform for lithium battery CT inspection includes a frame, a guide slide, a damping buffer, and a buffer mechanism; The top of the frame is set as an inclined surface, with the high end of the inclined surface corresponding to the conveyor belt and the low end of the inclined surface corresponding to the industrial CT equipment; and an opening is provided in the middle of the inclined surface, in which a guide slide is installed to guide the movement of the chassis holding the lithium battery. The damping buffer is mounted on the frame, and the telescopic end of the damping buffer protrudes from the surface of the guide slide. The frame has a buffer mechanism at the lower end of its inclined surface.

[0007] Furthermore, the guide slide includes an adjustment mechanism, a baffle, and a roller. There are two adjustment mechanisms, which are fixedly installed on the inner side of the opening at the top of the frame. The two adjustment mechanisms are fixedly connected to a baffle. Multiple positioning cylinders are installed on the opposite surfaces of the two baffles. The multiple positioning cylinders are evenly arranged along the length of the inclined surface, and the two opposite positioning cylinders are respectively inserted into the ends of the rollers.

[0008] Furthermore, the adjustment mechanism includes an electric push rod and a guide rod, wherein the electric push rod is installed inside the frame, the telescopic end of the electric push rod is fixedly connected to the baffle, one end of the guide rod is fixedly connected to the baffle, and the other end of the guide rod passes through the frame.

[0009] Furthermore, the outer edge surface of the roller is provided with a rubber layer.

[0010] Furthermore, the damping buffer is configured as two, with the two damping buffers located on the same vertical plane.

[0011] Furthermore, the buffer mechanism includes a spring and a buffer plate, wherein the end of the spring is fixedly mounted on the frame, and the head of the spring is fixedly connected to the buffer plate.

[0012] The technical solution of this utility model has at least the following advantages and beneficial effects: This utility model discloses a guided transport platform for lithium battery CT inspection. It adopts an inclined surface design and uses gravity to slide down naturally as the main power source, replacing the traditional belt, chain or robot drive method. This significantly reduces power consumption and operating noise, which is in line with the concept of green manufacturing. The overall structure is compact, eliminating the need for a complex transmission system and external power device, making the structure simpler. This not only reduces the equipment manufacturing cost, but also reduces the frequency and difficulty of later maintenance, making it particularly suitable for industrial environments with continuous operation.

[0013] In addition, by setting guide slides and damping buffers on the inclined surface, the movement trajectory and speed of the chassis or battery during the transfer process are effectively controlled, avoiding deviation or impact caused by inertia. The damping buffer can provide controllable resistance at key positions to ensure that the speed of the battery is reduced to a safe range before it reaches the CT scanning station. Combined with the precise interception of the buffer mechanism, the lithium battery and chassis can be accurately stopped at the end of the frame.

[0014] In addition, the guide slide adopts an adjustable design, and the baffle is driven to move by an electric push rod, which can flexibly adjust the roller spacing to adapt to batteries or trays of different sizes; while the roller is covered with a rubber layer, which increases the coefficient of friction and avoids scratching the surface of the battery.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Example

[0018] like Figure 1 The guide transport platform for lithium battery CT detection shown includes a frame 1, a guide slide 2, a damping buffer 3, and a buffer mechanism 4; The top of the frame 1 is set as an inclined surface, with the high end of the inclined surface corresponding to the conveyor belt and the low end of the inclined surface corresponding to the industrial CT equipment. The inclination angle of the inclined surface is 5-15° to ensure that the chassis or tray holding the lithium battery can slide down smoothly and at a constant speed under the action of gravity, while avoiding speed loss due to excessive angle. The middle of the inclined surface is provided with an opening 11, and a guide slide 2 for guiding the chassis holding the lithium battery is installed in the opening 11. The slide 2 is used to guide the chassis to move along a predetermined path to prevent it from deviating or tipping over during the movement. The damping buffer 3 is mounted on the frame 1, and its telescopic end protrudes from the surface of the guide rail 2, i.e., the section with higher chassis speed. The damping buffer 3 is a hydraulic damping buffer. The slowing principle of the damping buffer 3 is as follows: when the chassis passes the position of the damping buffer 3, the damping buffer 3 will apply a certain resistance to gradually reduce the chassis's downward speed and prevent it from impacting the terminal structure at excessive speed. In addition, there are two damping buffers 3, located on the same vertical plane. There are two possible arrangements for these two damping buffers 3: Firstly, the line connecting the two damping buffers 3 is parallel to the sliding direction of the lithium battery, meaning that the two damping buffers 3 can contact the chassis of the lithium battery in sequence, thereby achieving dual deceleration of the chassis, which has a better slowing effect for chassis with a smaller bottom area; secondly, the line connecting the two damping buffers 3 is perpendicular to the sliding direction of the lithium battery, meaning that the two damping buffers 3 contact the chassis simultaneously, which has a better slowing effect for chassis with a larger bottom area.

[0019] The frame 1 is provided with a buffer mechanism 4 at the lower end of the inclined surface; In addition, the buffer mechanism 4 includes a spring and a buffer plate. The end of the spring is fixedly installed on the frame 1, and the head of the spring is fixedly connected to the buffer plate. That is, multiple springs are fixedly arranged between the buffer plate and the frame 1 to ensure the stability of the buffer plate. When the chassis slides to the end of the slope, the speed of the chassis is already very low due to the slowing effect of the damping buffer 3. At this time, the chassis first contacts the buffer plate, and the spring is compressed to absorb the impact energy and achieve flexible stopping, so that the lithium battery and the chassis can accurately stop at the end of the frame 1. Example

[0020] As one embodiment, this embodiment further optimizes the adjustability and applicability of the guide slide 2 to accommodate a wider variety of battery specifications and tray sizes.

[0021] The guide slide 2 includes an adjustment mechanism 21, a baffle 22 and a roller 24. There are two adjustment mechanisms 21. The two adjustment mechanisms 21 are respectively fixedly installed on the inner side of the top opening 11 of the frame 1. The two adjustment mechanisms 21 are respectively fixedly connected to a baffle 22. Multiple positioning cylinders 23 are installed on the opposite surfaces of both baffles 22. The positioning cylinders 23 are evenly arranged along the length of the inclined plane. The two opposite positioning cylinders 23 are respectively inserted into the ends of the rollers 24. The positioning cylinders 23 are embedded with bearings. The two ends of the rollers 24 are inserted into the bearing holes to achieve low-resistance rotation of the rollers 24. These rollers 24 together form a low-friction rolling contact surface to support the chassis and guide its direction. In particular, the outer edge of the rollers 24 is provided with a rubber layer. This rubber layer can increase the friction with the bottom of the chassis to prevent slippage and ensure smooth sliding. On the other hand, its elasticity can play a certain role in buffering and shock absorption, protecting the battery from rigid impact, and also effectively reducing rolling noise. The spacing of the rollers 24 is designed according to the length of the chassis to ensure that at least three rollers 24 support the chassis at any position, ensuring the stability of the transfer process. The adjustment mechanism 21 includes an electric push rod 211 and a guide rod 212. The electric push rod 211 is installed inside the frame 1, and its telescopic end is fixedly connected to the baffle 22. One end of the guide rod 212 is fixedly connected to the baffle 22, and the other end of the guide rod 212 passes through the frame 1. By controlling the extension and retraction of the electric push rod 211, the distance between the two baffles 22 can be adjusted synchronously, thereby changing the effective working width of the roller 24 to adapt to different sizes of chassis or battery trays. At the same time, the end of the roller 24 remains inside the positioning cylinder 23, so that the roller 24 can still perform the function of transfer.

[0022] This embodiment, through its highly adjustable guiding structure and multi-level buffering mechanism, not only enhances the adaptability to batteries of different specifications, but also improves the safety and positioning accuracy of the transfer process, making it particularly suitable for flexible production lines with multiple varieties and small batches.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
