Description

Technical Field

[0001] This utility model relates to the field of battery module handling technology, and in particular to an elevator. Background Technology

[0002] In the factory quality inspection of lithium battery modules, each module weighing 25-50kg undergoes rigorous multi-round charge-discharge cycle testing to comprehensively verify key indicators such as range performance, capacity retention, and cycle life. During testing, the modules are placed in a constant temperature and humidity environment, and standardized charge-discharge currents are applied using professional battery testing equipment to simulate a complete charge-discharge cycle under real-world usage scenarios. This stringent testing process accurately assesses the battery module's capacity decay rate, internal resistance change trend, and thermal management performance, ensuring that each module meets the high standards of battery consistency, safety, and cycle life required by electric vehicles or energy storage systems.

[0003] Due to the heavy weight of the modules, they are prone to instability during manual handling. First, operators need to move the heavy modules from the storage location to the testing equipment, complete the test, and then transfer them to the next process, resulting in low work efficiency and rapid exhaustion of workers. Second, there is a risk of modules falling during manual handling, which may damage the battery modules and, more seriously, cause safety hazards such as short circuits and leaks. Third, the positioning accuracy of manual operation is difficult to guarantee, and misalignment of test interfaces often occurs, leading to test interruptions or abnormal data, affecting test efficiency and accuracy.

[0004] To solve the above problems, this utility model proposes an elevator. Utility Model Content

Specifically, guide rails 15 are fixedly mounted on both sides of the inner wall of the frame 1, and limit wheels 16 are rotatably mounted on the side plates 2. The limit wheels 16 are rotatably mounted inside the guide rails 15. The side plates 2 slide within the guide rails 15 through the limit wheels 16, ensuring a smooth and non-deviation-free lifting process, reducing frictional wear, improving the service life of the equipment, and enhancing the rigidity and stability of the lifting mechanism.

[0027] A horizontal plate 3 is fixedly installed on the side plate 2, and L-shaped robotic arms 4 for supporting the battery pack 11 are slidably installed at both ends of the horizontal plate 3. The L-shaped robotic arms 4 are slidably installed at both ends of the horizontal plate 3.

[0028] By adopting the above technical solutions, the lifting position can be flexibly adjusted to adapt to battery packs 11 of different sizes, thereby improving the versatility and adaptability of the equipment.

[0029] Two fixed seats 5 are fixedly installed on the inner bottom surface of the frame 1. A chain 6 is fixedly connected to each fixed seat 5. An electric cylinder 7 is fixedly installed on the inner bottom surface of the frame 1. A lifting plate 8 is fixedly installed at the output end of the electric cylinder 7. A sprocket 9 is rotatably installed on both sides of the lifting plate 8. The chain 6 is engaged with the corresponding sprocket 9. The end of the chain 6 away from the fixed seat 5 is fixedly connected to the upper end surface of the horizontal plate 3.

[0030] By adopting the above technical solution, the electric cylinder 7 drives the lifting plate 8, which in turn drives the horizontal plate 3 to rise and fall through the meshing transmission of the sprocket 9 and the chain 6, ensuring efficient and stable power transmission, reducing the risk of slippage, and improving lifting accuracy and reliability.

[0031] In this embodiment of the utility model: side base frames 12 are fixedly installed on both bottom ends of the frame 1, and a support column 13 is fixedly connected to the end of the side base frame 12 away from the frame 1, and an emergency stop button 14 is installed on the support column 13.

[0032] By adopting the above technical solutions, the side base frame 12 and the support column 13 enhance the overall stability of the frame 1, and the emergency stop button 14 provides an emergency braking function to ensure that the equipment can be stopped quickly in case of abnormality, thereby improving operational safety.

[0036] By adopting the above technical solution, the limit switch 17 abuts against the side plate 2 to accurately control the lifting stroke, prevent overtravel, protect the equipment structure, and ensure the consistency of each lifting position.

[0037] Multiple support feet 18 are evenly fixedly installed at the bottom of the frame 1 and the side base frame 12.

[0038] It should be noted that all the devices in this application are common devices on the market, and can be selected according to specific needs. Here we are just using them without making any structural or functional improvements, and we will not go into details here.

[0039] Working principle:

[0040] During operation, after the AGV trolley 10 accurately transports the battery pack 11 to the designated loading area on both side base frames 12, the electric cylinder 7 immediately starts, driving the lifting plate 8 to rise smoothly in the vertical direction. The movement of the lifting plate 8 is converted into the synchronous rising action of the horizontal plate 3 through the meshing transmission of the high-strength chain 6 and the sprocket 9. The rising of the horizontal plate 3 drives the L-shaped robotic arm 4 to lift, ultimately raising the material to the predetermined working height. To ensure absolute stability during the lifting process, the side plates 2 fixedly installed on the horizontal plate 3 form a sliding engagement with the guide rails 15 on the frame 1 through the high-precision limit wheels 16 configured on both sides, effectively eliminating shaking during the lifting process.

[0041] When side plate 2 rises to the preset working position, it reliably contacts the high-sensitivity limit switch 17. The limit switch 17 immediately sends a signal to control the electric cylinder 7 to stop accurately, ensuring positioning accuracy. This achieves seamless docking with the AGV trolley and improves automation efficiency.

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.
