Description

Technical Field

[0001] This utility model relates to the field of battery cell processing technology, and specifically discloses a battery cell conveying device. Background Technology

[0002] Batteries, as crucial energy storage components, are widely used in new energy vehicles, consumer electronics, and energy storage systems. In battery production, the cell, as the core component, undergoes multiple processes including winding / stacking, packaging, electrolyte injection, and formation. The seamless integration between these processes heavily relies on automated conveying devices. These cell conveying devices must ensure both efficient transport and precise cell positioning with no surface damage, which is critical for production yield and equipment compatibility.

[0003] In existing technologies, cell stepping conveying often relies on complex mechanical structures (such as cams and indexing plates) or multiple independent drive units working together. This results in problems such as high equipment costs, difficult maintenance, and inflexible step adjustment. Some devices use rigid clamping or lifting mechanisms, which are prone to scratching the cell surface due to vibration or friction. Furthermore, each action can only achieve a fixed step displacement, making it difficult to adapt to the conveying needs of cells of different specifications. In addition, traditional solutions require multiple switching of the load-bearing structure during cell transfer, which can easily introduce positioning deviations and affect the efficiency of process connections. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Please see Figure 1-3 A battery cell conveying device includes a base plate 1, a plurality of columns 2 are fixedly connected to the upper end face of the base plate 1, two parallel and front-to-back fixed support rods 3 are fixedly connected to the top of the plurality of columns 2, two front-to-back movable support rods 4 are arranged on the inner side of the two fixed support rods 3, and the two movable support rods 4 are fixedly connected to each other by two connecting rods 6, and a plurality of evenly distributed support grooves 5 are opened on the upper end face of both the fixed support rods 3 and the movable support rods 4.

[0022] Two vertical electric actuators 9 are arranged on the top of the base plate 1, and the output ends of the two vertical electric actuators 9 are fixedly connected to the bottom ends of the two connecting rods 6 respectively.

[0023] In this embodiment: the battery cell conveying device fixes two parallel fixed support rods 3 through the column 2 on the base plate 1, and a movable support rod 4 is set inside the column 2. The movable support rod 4 is connected by the connecting rod 6. In the initial state, the battery cell is placed in the support groove 5 of the fixed support rod 3. When the vertical electric push rod 9 is activated, the movable support rod 4 is lifted up, and the support groove 5 at the upper end of the movable support rod 4 lifts the battery cell from the bottom and separates it from the fixed support rod 3. Then the horizontal electric push rod 12 pushes the mounting plate 13 and the movable support rod 4 to move laterally as a whole, so that the support groove 5 at the upper end of the movable support rod 4 moves to the right by one step (i.e., the distance between adjacent support grooves 5). After displacement is completed, the vertical electric push rod 9 retracts, the movable support rod 4 descends, and the battery cell falls back into the support groove 5 of the fixed support rod 3. The entire process achieves precise step-by-step conveying of the battery cell. By alternating lifting and translation of the fixed support rod 3 and the movable support rod 4, the complex mechanical structure of traditional step-by-step conveying is simplified, reducing manufacturing costs and maintenance difficulty. The horizontal movement of the movable support rod 4 is driven by a single set of transverse electric push rods 12, which, together with the slide rail 7 and slider 8, ensures displacement synchronization and avoids coordination errors of multiple drive units. The V-shaped design of the support groove 5 and the rubber pad effectively disperse the contact stress of the battery cell and reduce the risk of surface damage. The overall structure of the device is compact, and the step distance is precisely controlled by the spacing of the support groove 5, adapting to the flexible production needs of battery cells of different specifications. In addition, the battery cell is supported by the support groove 5 throughout the process, without the need for additional clamping mechanisms. The action is smooth and reliable, significantly improving the efficiency of process connection and production yield.

[0024] As a technical optimization of this utility model, two front-to-back sliding rails 7 are fixedly connected to the left and right sides of the upper end face of the base plate 1. Slider 8 is slidably connected to the upper end face of the four sliding rails 7. Mounting plates 13 are fixedly connected to the upper end face of the two sliders 8 on the same side. Two vertical electric push rods 9 are respectively installed on the upper end face of the two mounting plates 13.

[0025] In this embodiment: the slide rail 7 cooperates with the slider 8 to make the mounting plate 13 drive the vertical electric push rod 9 to move horizontally along the slide rail 7, ensuring the stability of the horizontal movement trajectory of the movable bearing rod 4 and avoiding the positioning deviation of the battery cell caused by the offset.

[0026] As a technical optimization of this utility model, a horizontal electric push rod 12 is also installed on the upper end surface of the base plate 1. A vertically arranged end plate 10 is fixedly connected to the outer wall of the right mounting plate 13. The output end of the horizontal electric push rod 12 is fixedly connected to the end plate 10. A bracket 11 is fixedly connected to the upper end surface of the base plate 1. The horizontal electric push rod 12 is installed on the upper end of the bracket 11.

[0027] In this embodiment: the horizontal electric actuator 12 drives the right mounting plate 13 to move through the end plate 10, and the vertical electric actuators 9 on both sides move synchronously to ensure the synchronicity and consistency of the overall translation of the movable bearing rod 4.

[0028] As a technical optimization of this utility model, the number of support grooves 5 located on the upper end face of the fixed bearing rod 3 and the movable bearing rod 4 and the distance between adjacent two are equal.

[0029] In this embodiment, the number and spacing of the support grooves 5 of the fixed support rod 3 and the movable support rod 4 are equal, ensuring that the battery cell is always evenly supported during the lifting, translation and falling process, and avoiding tilting or uneven force.

[0030] As a technical optimization of this utility model, the cross-section of the support groove 5 is V-shaped.

[0031] In this embodiment, the V-shaped structure of the support groove 5 conforms to the cylindrical outline of the battery cell, increases the contact area, disperses pressure, and, together with the rubber pad, further buffers vibration and prevents surface scratches.

[0032] As a technical optimization of this utility model, both the vertical electric actuator 9 and the horizontal electric actuator 12 are electrically connected to the external control system.

[0033] In this embodiment, the vertical electric actuator 9 and the horizontal electric actuator 12 are connected to an external control system (such as a PLC or industrial computer) via electrical signals. The control system sends commands to the electric actuators according to a preset program to control the timing, stroke, and speed of their extension and retraction movements. Since the control system controls the operation of the electric actuators, which is a mature existing technology, its electrical connection relationship, specific circuit structure, and working principle will not be described in detail here.

[0034] As a technical optimization of this utility model, a rubber pad is fixedly connected to the inner side of the support groove 5.

[0035] In this embodiment, a rubber pad is fixedly connected to the inner side of the support groove 5 to reduce wear on the surface of the battery cell, while increasing friction and anti-slip effect.

[0036] The working principle and usage process of this utility model are as follows: In use, the multiple support grooves 5 at the upper end of the fixed support rod 3 are used to support the battery cells. The multiple battery cells are evenly placed inside the multiple support grooves 5 at the upper end of the two fixed support rods 3. When the two vertical electric push rods 9 are activated, they drive the two movable support rods 4 to move upward. The two movable support rods 4 rise between the two fixed support rods 3 and lift the multiple battery cells from the bottom. At this time, the multiple battery cells are located inside the multiple support grooves 5 at the upper end of the two movable support rods 4. Furthermore, the horizontal electric push rod 12 pushes the right mounting plate 13 and the right vertical electric push rod 9. The entire device moves laterally, with the right vertical electric push rod 9, the movable bearing rod 4, and the left vertical electric push rod 9 forming a single unit. This allows the movable bearing rod 4 to move horizontally, causing multiple battery cells to move one unit distance to the right. This unit distance is the distance between two adjacent support slots 5. Further, the two vertical electric push rods 9 retract, causing the two movable bearing rods 4 to move downwards. This allows the multiple battery cells to be repositioned inside the multiple support slots 5 at the upper ends of the two fixed bearing rods 3. This process of horizontally conveying battery cells one unit distance is described above. When the device operates in a cycle, it can continuously convey battery cells.
