Description

TECHNICAL FIELD

[0001] The present application relates to the field of engineering vehicle battery, in particular to an adaptive battery compartment rolling device for engineering vehicle oil-to-electricity and a use method thereof. BACKGROUND

[0002] Currently, in the engineering vehicle forklift "oil-to-electricity" project, the main method for manufacturing the battery compartment for the square hard-shell power battery is the roll forming process. The process utilizes a series of sequentially arranged rollers to gradually form a cup-shaped square shell with precise dimensions by gradually bending the aluminum alloy metal plate in progress through multiple groups of rollers.

[0003] However, in the gradual bending process, the production line flexibility required for rolling is poor. Once the battery shell size or specification changes, the entire set of rotating rollers and support frames must be redesigned and replaced, making it difficult to adapt to the personalized needs of multiple vehicle types and small batches in the "oil-to-electricity" market. Secondly, during maintenance after rolling, when excessive wear of a roller is found, the entire system must be shut down and the shell removed, and the bearing and roller must be replaced, making maintenance time-consuming and labor-intensive. Finally, during the rolling process, the upper and lower roller pressures need to be consistent, but they are easily affected by mechanical deviation, stress deformation, and plate size during the rolling process, resulting in uneven parallelism of the axes of multiple rollers, causing misalignment and non-collinear situations, which can cause unintended longitudinal bending of the formed plate, damage the straightness, cause edge waves, and result in uncontrolled local thickness. In view of the above, the present application provides an adaptive battery compartment rolling device for engineering vehicle oil-to-electricity and a use method thereof to solve the above problems.

[0041] According to the accompanying drawings Figures 1 to 9 As shown, the use method includes:

[0042] S1. Installation and fixation: design the detachable roller 3 according to the size of the metal plate required, and insert it on the rotating rod 5, and move the detachable roller 3 to the middle under the driving of the first servo motor 22, and finally fix and lock the detachable roller 3 in the middle under the driving of the second servo motor 62;

[0043] S2. Processing and monitoring: during the processing, the displacement sensor and the pressure sensor continue to run and monitor the specific situation;

[0044] S3. Shutdown and disassembly: after the processing is completed, the first servo motor 22 drives the detachable roller 3 to move to the upper and lower ends, so that the detachable roller 3 leaves the limiting long baffle 4, and the limiting long baffle 4 is disassembled, the first servo motor 22 is adjusted up and down according to the distance and fluctuation of the rotating rod 5 monitored by the displacement sensor, so that the axes of the multiple detachable rollers 3 are located on the same horizontal line, the second servo motor 62 adjusts the movement of the limiting long baffle 4 according to the pressure fluctuation of the limiting long baffle 4 monitored by the pressure sensor, so that the detachable roller 3 maintains a stable state, and stops when frequent fluctuations are monitored.

[0045] In the installation and fixing stage of the method S1, the operator only needs to replace the detachable roller 3 module of the corresponding specification, and then start the system preset program, and the device can automatically complete the synchronous adjustment of the distance between the two groups of detachable rollers 3 and the width positioning and locking of the limiting long baffle 4. This system converts the mechanical transformation and debugging work which originally relies on rich experience and takes hours or even days into a standardized and repeatable automatic process, thereby improving the flexibility and response speed of the production line. In the processing monitoring stage of the method S2, the sensor network collects two key physical quantities in real time: one is the real-time position of each rotating rod, which is used to reflect the roller axis height, and the other is the clamping pressure of the limiting long baffle on the roller. These data are transmitted to the control system and compared with the preset process parameters. Once a deviation is detected, such as roller micro-displacement or pressure fluctuation caused by uneven stress, the control system will drive the first servo motor 22 to fine-tune the roller vertical height or drive the second servo motor 61 to fine-tune the lateral clamping force according to the logic of the method, forming a dynamic closed-loop control loop of monitoring-feedback-execution, which can compensate for mechanical errors and material fluctuations in real time, and actively stabilize the pressure center of multiple detachable rollers 3 in the ideal coplanar state, thereby ensuring the high precision and high stability of the forming process at the root.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
