Solder Supply Device Segmented Piston Nozzle Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solder supply devices face complexity in exchanging solder containers due to the elastic force between the piston and the container, making it difficult to remove the piston and requiring multiple steps for container exchange.
Innovation Solution
A solder supply device with an outer tube and air chamber mechanism that allows relative movement of the solder container and piston using air pressure, along with a lock mechanism for detachable nozzle and piston attachment, reducing the elastic force and simplifying the exchange process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the piston is formed from elastically deformable material to adhere to the inside wall surface of the solder container, then solder can be supplied without any solder being left inside the container, but it becomes difficult to remove the piston from inside the solder container
Solution Approach 1:
The device is divided into two separate components: the piston that remains in the solder container and the nozzle that is detached. The piston is formed from elastically deformable material to ensure complete solder supply, while the nozzle is separately attachable and detachable, allowing easy removal without compromising solder supply completeness.
Solution Approach 2:
The nozzle is extracted from the piston structure, allowing the piston to remain in the solder container while the nozzle is detached. This separation enables the piston to maintain its elastic deformation for complete solder supply while the nozzle can be easily removed and replaced.
2Reliability
If the piston integrated with the nozzle is held by a holding member, then the nozzle can be held securely, but the exchange work of the solder container becomes even more complex
Solution Approach 1:
The holding member is designed to hold only the nozzle separately from the solder container. The piston remains in the container while the nozzle with its holding member can be detached as a separate unit, simplifying the exchange process by reducing the number of components that need to be manipulated together.
Solution Approach 2:
Instead of attaching the nozzle directly to the solder container, the invention inverts the attachment relationship by using a holding member that secures the nozzle independently. This allows the nozzle to be held securely while enabling easy detachment and exchange without complex operations.
3Reliability
If the elastic force between the piston and inside wall surface is increased to ensure complete solder supply, then solder can be fully extracted, but the force required to remove the piston increases
Solution Approach 1:
The piston is segmented from the nozzle, allowing the piston to maintain high elastic force for complete solder extraction while the nozzle is separately removable. This segmentation enables the piston to exert sufficient elastic force against the solder container wall without requiring high force for removal, as the nozzle portion can be detached independently.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy removal of the piston and solder container, reducing the number of steps for exchange and allowing for a compact, simple construction without the need for air cylinders or electromagnetic motors, while ensuring efficient solder supply.
Implementation Method 1
the solder container and the piston are relatively moved by air being supplied to an air chamber that is demarcated by the other end of the solder container and the other end of outer tube

AI summary
Solder supply device 26 includes solder cup 70 that is tubular and open at one end, nozzle section 88 for for ejecting solder from the solder cup, flange section 90 that is fixedly provided on an outer circumferential section of the nozzle section and that is engaged inside of the solder cup, and inner tube 76 an end of which holds the nozzle section and the other end of which extends from the opening of the solder cup; the flange section is formed from material that is elastically deformable and the flange section is engaged inside the cup with an outer edge section of the flange section in an elastically deformed state. The elastic force arising between the outer edge section of the flange section and the solder cup is smaller than the holding force of the nozzle section by the inner tube. By separating the inner tube and the solder cup, the flange section integrated with the nozzle section is removed from inside the solder cup. By this, the solder cup is easily removed from the solder supply device.
