Description

Technical Field

[0001] This utility model relates to the technical field of overhead crane traveling mechanism, and more particularly to a soft-pack battery overhead crane traveling mechanism for a heavy-duty double ball screw driven overhead crane lifting equipment. Background Technology

[0002] The battery formation process directly affects the battery's capacity, cycle performance, self-discharge performance, and high-temperature performance. In the manufacturing process of lithium-ion batteries, the formation process utilizes robotic grippers to perform the gripping action. These grippers are driven and controlled by corresponding opening devices to complete the gripping action. Since existing battery formation equipment includes not only the gripping mechanism but also the device that drives the gripping mechanism to open, adding a device to move the gripping mechanism while ensuring the opening device and gripping structure are compatible is currently beyond the level of automation required by current lithium battery formation equipment. This is indeed a technical problem that needs to be solved, and currently, those skilled in the art have not yet developed an effective solution for adding this device to the equipment.

[0003] After a focused analysis of the shortcomings of existing battery formation overhead crane equipment by those skilled in the art, the main technical problem that needs to be solved is that traditional lithium battery formation overhead cranes do not have an automatic integrated lifting device, cannot be combined with robotic grippers to form an integrated structure, and cannot be adapted to processing requirements. At the same time, when the same robotic arm has multiple synchronous grippers to grip battery cells, the limited space under the table of traditional equipment makes it impossible to install an appropriate lifting device, which further reduces operability. Even if some lifting components are added under the table, the vertical height is insufficient to meet the distance requirements for the vertical movement of the gripper mechanism.

[0004] When an overhead crane malfunctions and requires repair, it needs to be transported to the ground for maintenance. Once repairs are complete, the crane is raised to the required height and positioned on the upper fixed track within the maintenance area. Most current overhead crane lifting systems place the crane on a movable track, lifting it to align with the upper fixed track in the maintenance area to increase the crane's height. The mechanism for lifting the movable track is often modular. However, this modular approach is unsuitable for long-distance transport, such as exceeding 4 meters in height. Longer modules are more difficult to manufacture and more expensive, increasing the overall cost of the equipment. Furthermore, because the movable track needs to align with the upper fixed track, an electrically controlled locking mechanism is installed between them to ensure alignment accuracy. This is costly, and the locking mechanism is susceptible to vibrations from the movable track and / or the upper fixed track, leading to electrical control failure and poor stability.

[0005] Chinese patent CN208246842U discloses a mobile manipulator for lithium battery formation overhead cranes. The manipulator uses a power unit mounted above a fixed frame of the overhead crane's mobile manipulator equipment. Below the fixed frame is a combined gripper for holding battery cells. The mobile manipulator includes: several guide rails, each guide rail's top end fixedly connected to a top plate above the fixed frame, and each guide rail's bottom end fixedly connected to a movable frame below the fixed frame; a transmission mechanism including two drive wheels driven by a drive belt, the drive wheels being located in the central area of ​​the top plate; and a vertical lifting mechanism including a lead screw parallel to the guide rails and connected to the drive wheels. The lead screw is connected to the movable frame via a connecting assembly and converts the rotational motion into linear motion, causing the movable frame to move the gripper up and down along the guide rails. This invention solves the problems of the top drive mechanism and lifting mechanism required by this invention. The entire lifting mechanism is vertically positioned above the robotic arm equipment, driving the moving frame below to move the robotic arm gripper up and down, improving the efficiency of gripping battery cells. It fully utilizes the space above the fixed frame table, solving the problems of large space occupation and redundant mechanical components in traditional battery formation overhead crane robotic arm equipment that require an additional lifting mechanism, thus greatly improving production efficiency. A lead screw converts rotational motion into the motion of lifting the moving frame. Since the lifting mechanism and gripper form an integrated structure, the lifting component can directly cooperate with the applied robotic arm gripper to grip battery cells for integrated lifting and moving, saving costs and facilitating a higher level of automation. By using a guide rail extending from above to below the table, the moving frame has sufficient lifting space to meet the vertical movement distance of the gripper mechanism, solving the problem that traditional battery formation overhead crane equipment cannot adjust its own height.

[0006] Chinese patent CN210910061U discloses a robotic arm for lithium battery formation overhead cranes, including a fixed plate, a force sensor, a connecting plate, a gripping device, a driving device, and a control device. The gripping device is disposed on the connecting plate, which is connected to the fixed plate via the force sensor. The driving device drives the gripping device. The force sensor detects the pressure between the fixed plate and the connecting plate. Both the force sensor and the driving device are electrically connected to the control device. This design solves the problem of the force sensor transmitting detected pressure information to the control device in real time during operation. Before operation, a pressure threshold is set via the control device. The system compares the pressure detected by the force sensor with a threshold value in real time. During operation, the gripper inserts the battery cell into the cell. After formation, the battery cell will generate gas. If the gripper happens to grip the part of the battery cell that has bulged excessively due to gas generation, and if the battery cell becomes misaligned, it may not be placed in the shelf and may get stuck in the middle of the rocket head of the formation cell. The gripper will continue to press down on the battery cell. At this time, the pressure detected by the force sensor will become very high. When it exceeds the threshold, the control device will send a signal to the control system of the overhead crane to stop the gripper from pressing down, preventing damage to the battery cell. This achieves the effects of reducing defective products, lowering production costs, and improving production efficiency. This formation robot has a simple structure, is easy to use, and is highly practical. Summary of the Invention
