Technical Field

[0001] This utility model relates to the field of battery production equipment technology, and in particular to a multifunctional manipulator structure for handling battery cells with corrective caps. Background Technology

[0002] In the lithium battery production process, battery handling and battery cap installation are crucial steps. Current traditional handling equipment has several shortcomings: most equipment can only perform simple battery gripping and handling actions, lacking the ability to detect and correct the battery cap's posture; because the cap is prone to misalignment, tilting, or other abnormal postures during installation or transport, direct subsequent assembly will lead to reduced assembly accuracy, affecting the battery's sealing, safety, and overall performance.

[0003] In existing technologies, some devices with attitude adjustment functions suffer from problems such as complex structure and poor versatility: they can either only adjust the overall attitude of the battery or rely on a large number of sensors and complex algorithms, resulting in high equipment costs, frequent failures, and difficult maintenance. Furthermore, existing equipment requires frequent changes of tooling fixtures when handling batteries of different specifications, making operation cumbersome and severely restricting production efficiency and flexibility. Therefore, developing a multifunctional device that can accurately detect and correct the attitude of battery caps, achieve efficient handling, and is highly versatile and structurally simple is of great significance for improving the quality and efficiency of lithium battery production. Utility Model Content

[0004] The purpose of this utility model is to provide a multifunctional manipulator structure for handling battery cells with corrective caps, which solves the problems of existing handling equipment being unable to effectively detect and correct the posture of battery caps, having poor versatility, and having a complex structure. The manipulator uses a clamping mechanism with cylinders and springs to stably grasp batteries of different specifications and simultaneously correct the posture of the caps, ensuring the efficiency, stability, and versatility of the handling process, and improving the quality and efficiency of cap assembly in lithium battery production.

[0005] To achieve the above objectives, a multifunctional manipulator structure for handling battery cells with corrective caps is provided, comprising a moving mechanism and a lifting mechanism.

The mounting base is fixedly connected to the side of the fixing plate closest to the moving mechanism. A clamping mechanism is fixedly connected to the lower end of the connecting plate by bolts. The clamping mechanism includes a fixed clamping arm and a movable clamping arm. Cylinders are fixedly connected to both ends of the outer side of the fixed clamping arm. A spring adjustment assembly is fixedly connected to the fixed clamping arm located between the two cylinders. A limit rod is fixedly connected to the inner side of the fixed clamping arm. A slope correction rod and a guide seat are fixedly connected to the inner side of the movable clamping arm.

[0006] According to the multifunctional correction cap handling robot structure, the limiting rod and the inclined plane correction rod are arranged opposite to each other, and the guide seat is located on the lower side of the inclined plane correction rod.

[0007] According to the multifunctional correction cap handling robot structure, a battery is provided on the lower side of the limiting rod, the battery is placed on the platform, and a cap is provided on the upper end.

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Reference Figure 1-4This utility model embodiment discloses a multifunctional corrective cap handling robot structure for battery cells, which includes a moving mechanism 1 and a lifting mechanism 2. The moving mechanism 1 and the lifting mechanism 2 have the same structure. The moving mechanism 1 consists of a track housing 11, a screw 13, a guide bar 14, a slider 15, a drive motor 16, and a mounting base 17. The moving mechanism 1 adopts a high-precision linear guide rail, arranged horizontally, with a length of 1 to 2 meters (set as needed), to achieve stable horizontal movement of the battery 7. The vertical lifting range of the lifting mechanism 2 is 0-0.8 meters, with a positioning accuracy of ±0.3 mm. Both the screw 13 and the guide bar 14 are located within the mounting groove 12, with the guide bar 14 positioned on both sides of the screw 13. The drive motor 16 is fixedly connected to one end of the track housing 11, and its output end is fixedly connected to the screw 13 via a coupling. The track housing 11 has a mounting groove 12 within it. The slider 15 is slidably connected to the guide bar 14 on its inner side, and its outer side is fixedly connected to the mounting base 17 via bolts. The screw 13 is a precision-ground ball screw, driven by the drive motor 16, ensuring the straightness and repeatability of horizontal movement. The guide bar 14 is a double-row linear slide rail, symmetrically distributed on both sides of the screw 13, forming a "screw + guide rail" composite transmission structure, effectively eliminating the off-center load error of a single transmission pair and improving motion stability. When the drive motor 16 starts, the screw 13 drives the slider 15 to reciprocate along the mounting groove 12 of the track housing 11, thereby achieving the horizontal transport of the battery cells 7. By adjusting the motor pulse count, the movement distance can be precisely controlled to meet the material transfer requirements between different workstations. The output end of the lifting mechanism 2 is fixedly connected to a connecting plate 21, and a fixing plate 6 is fixedly connected to the side away from the connecting plate 21. The side of the fixing plate 6 closest to the moving mechanism 1 is fixedly connected to a mounting base 17. The lower end of the connecting plate 21 is fixedly connected to a clamping mechanism 3 by bolts. The clamping mechanism 3 adopts a symmetrical clamping arm (fixed clamping arm 31 and moving clamping arm 32) + double-acting cylinder 4 + adjusting spring combination 5, which is used to accurately grasp the battery 7. The clamping mechanism 3 includes a fixed clamping arm 31 and a movable clamping arm 32. Cylinders 4 are fixedly connected to both ends of the outer side of the fixed clamping arm 31. The cylinders 4 are ordinary double-acting single-piston cylinders (cylinder diameter 25mm, stroke 15mm) and are equipped with magnetic ring sensors for position detection. The correction rod is indirectly driven through a lever transmission mechanism. A spring adjustment assembly 5 is fixedly connected to the fixed clamping arm 31 between the two cylinders 4. The spring adjustment assembly 5 consists of a slide rod and a spring. The slide rod is slidably connected to the movable clamping arm 32, and the spring is sleeved on the slide rod and located between the fixed clamping arm 31 and the movable clamping arm 32. A limit rod 34 is fixedly connected to the inner side of the fixed clamping arm 31, and a slope correction rod 33 and a guide seat 35 are fixedly connected to the inner side of the movable clamping arm 32. The slope correction rod 33 is made of wear-resistant alloy material (Cr12MoV), and has been quenched (hardness HRC58-62). The rod body diameter is 6mm, and the working end is machined with a 30° correction slope (slope length 5mm), with a rounded corner (R0.8mm) at the top. The limit rod 34 is set opposite to the slope correction rod 33, and the guide seat 35 is located below the slope correction rod 33. The guide seat 35 and the slope correction rod 33 are precisely matched (fitting clearance 0.03~0.06mm) to ensure that the correction rod moves smoothly without jamming. A battery 7 is provided below the limit rod 34. There are several guide seats 35, which are arranged in a row. Each guide seat 35 corresponds to a battery 7. The battery 7 is placed on the platform and has a cap 71 on its upper end. When cylinder 4 pushes the clamping arm 32 to close, spring adjustment assembly 5 provides adaptive pressure, causing the inclined plane correction rod 33 to fit tightly against the edge of battery cap 71. If the cap is tilted, the inclined plane of the correction rod will apply a lateral torque, forcing the cap to automatically return to its upright position; the limit rod 34 limits the maximum correction angle to prevent excessive deformation. This process is completed synchronously with the clamping action, requiring no additional time.

[0018] Working principle: During use, the clamping mechanism 3, which is composed of cylinder 4 and spring, can stably grasp batteries 4 of different specifications and simultaneously correct the posture of cap 71, ensuring the efficiency, stability and versatility of the handling process, and improving the quality and efficiency of cap 71 assembly in the lithium battery production process.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
