Solution Overview

Problem

The manual replacement of pressing plates in battery manufacturing is inefficient, labor-intensive, and can lead to contamination and reduced production efficiency due to the need for shutting down the production line, posing risks of misoperation and impurity transfer.

Innovation Solution

A pressing plate replacing apparatus with a gripping mechanism, material rack, and rotating mechanism that allows automated replacement of pressing plates by switching between a feed and return rack position, enabling the gripping mechanism to operate without shutting down the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual replacement of pressing plate is performed, then operation simplicity is maintained, but productivity is reduced due to shutdown requirements and labor intensity

Engineering Contradiction:
Improveproduction efficiencyVSAvoidreplacement system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The pressing plate replacement system performs replacement operations automatically without requiring external manual intervention. The gripping mechanism autonomously grips, transports, and releases pressing plates between the welding device and material rack, enabling the system to service itself during operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The replacement system is divided into distinct functional modules: a gripping mechanism for handling pressing plates, a material rack with separate feed and return racks, and a rotating mechanism for position switching. This segmentation allows each component to perform its specific function efficiently while maintaining overall system simplicity.

Inventive Principle:
Principle #1Segmentation

2Productivity

If pressing plate replacement is performed during operation, then productivity is improved by continuous operation, but device complexity increases due to position switching requirements

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoidposition switching mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The material rack is designed with rotational capability, transforming from a static structure to a dynamic one that can switch between different positions. The rotating mechanism enables the material rack to alternately present the feed rack and return rack to the gripping mechanism, facilitating continuous pressing plate replacement during welding operations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The material rack serves multiple functions: it stores unused pressing plates in the feed rack, receives used pressing plates in the return rack, and switches between these functions through rotation. This multi-functionality allows a single structure to handle both supply and recycling of pressing plates, improving productivity without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Extent of automation

If automated gripping mechanism is used, then productivity is improved through automation, but device complexity increases due to additional mechanisms

Engineering Contradiction:
Improvepressing plate replacement automationVSAvoidgripping mechanism complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The gripping mechanism replaces manual mechanical operations with an automated gripping system. Instead of manual handling, the mechanism uses mechanical gripping actions controlled by a driving device to automatically grasp, transport, and release pressing plates, achieving automation while keeping the mechanical structure relatively simple.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If material rack rotation is implemented, then ease of operation is improved for switching between feed and return racks, but device complexity increases due to rotating mechanism

Engineering Contradiction:
Improverack switching convenienceVSAvoidrotating mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The material rack structure is designed with asymmetric positioning of the feed rack and return rack relative to the rotation axis. This asymmetric arrangement allows the rotating mechanism to efficiently switch between the two racks in a single rotational motion, improving operational convenience while minimizing the complexity of the rotating mechanism itself.

Inventive Principle:
Principle #4Asymmetry

AI summary

A pressing plate replacing apparatus, a welding device, and a pressing plate replacing method are disclosed in the present disclosure. The pressing plate replacing apparatus is configured to replace a pressing plate installed on a welding device. The pressing plate replacing apparatus includes a gripping mechanism, a material rack, and a rotating mechanism. The gripping mechanism is configured to grip the pressing plate, and the gripping mechanism is capable of reciprocating in a first direction. The material rack is located at one side of the welding device in the first direction, and the material rack includes a feed rack configured to store unused pressing plates and a return rack configured to recycle used pressing plates. The rotating mechanism is connected to the material rack and is configured to drive the material rack to rotate. The material rack, driven by the rotating mechanism, is capable of being switched between a first position and a second position. When the material rack is in the first position, the feed rack faces the gripping mechanism. When the material rack is in the second position, the return rack faces the gripping mechanism.
