Solution Overview
Problem
Traditional liquid injection devices for batteries face issues with weighing accuracy due to battery shaking during transportation and are often model-specific, leading to increased weighing errors and the risk of damage to the weighing mechanism.
Innovation Solution
A liquid injection device with a conveying mechanism, weighing mechanism, and guide mechanism that includes adjustable guide plates to secure the battery in place, allowing for precise weighing without model changes, and a lifting mechanism to transfer the battery to the weighing platform, reducing shaking and errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the weighing mechanism is arranged below the conveying mechanism with lifting mechanism for transfer, then the battery damage risk to weighing mechanism is reduced, but the battery shaking during up-down motion increases weighing error
Solution Approach 1:
The guide mechanism acts as an intermediary between the conveying mechanism and weighing mechanism. It includes guide plates that constrain the battery's lateral movement and a power member that controls the guide plates' positioning. This intermediary structure stabilizes the battery during transfer, reducing shaking-induced weighing errors while maintaining the protective arrangement of the weighing mechanism below the conveying mechanism.
2Manufacturing precision
If the liquid injection device is designed for a specific battery model, then the weighing mechanism can be optimized for that model, but model change operations are required when weighing different battery models
Solution Approach 1:
The guide mechanism incorporates a power member that enables dynamic adjustment of the guide plates' positions along the width direction. This allows the device to adapt to different battery models by adjusting the guide plate spacing, maintaining weighing precision across multiple models without requiring model change operations or reconfiguration of the entire weighing system.

AI summary
The present invention provides a liquid injection device, including a conveying mechanism (1), a weighing mechanism (2), a lifting mechanism (3) and a guide mechanism (4). The weighing mechanism (2) is positioned below the conveying mechanism (1). The lifting mechanism (3) is configured to transfer a battery on the conveying mechanism (1) to the weighing mechanism (2). The guide mechanism (4) includes a first guide plate (41), a second guide plate (42) and a power member (43). A distance between the second guide plate (42) and the first guide plate (41) may be adjusted through the power member (43), so that the liquid injection device may be compatible with batteries with different models. It is unnecessary to perform model change operation when the battery is changed, thus improving production efficiency. Since a gap between the second guide plate (42) and the first guide plate (41) forms a guide channel in a length direction (L) of the battery when the conveying mechanism (1) conveys the battery, the guide mechanism (4) may limit the battery in a width direction (W), thereby preventing the battery from being deviated towards two sides of the width direction (W) in the conveying process. The battery is fixed by the guide mechanism (4) when being weighed by the weighing mechanism (2), so that battery shaking is avoided and weighing error is reduced.
