Solution Overview
Problem
Existing suspended-type spot welding machines face challenges in allowing workers to clearly observe welding seams, particularly for various vehicle models, leading to potential welding deviations and reduced spot welding effectiveness.
Innovation Solution
A suspended-type spot welding device equipped with a camera mounted on an electrode holder to capture the welding seam, a display to show the seam's position, and a balancing weight to maintain the display's position, along with protective and cleaning mechanisms for the camera and display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the welding machine body is manually controlled to perform spot welding on automobile parts, then the welding operation can be performed on various vehicle models, but the welding seam becomes difficult to observe and welding deviation occurs
Solution Approach 1:
The patent uses a camera to capture images of the welding seam and displays them on a screen, creating a visual copy of the welding area. This allows workers to observe the welding seam clearly without directly viewing it, resolving the contradiction between welding versatility and seam visibility.
Solution Approach 2:
The patent introduces a camera and display system as an intermediary between the welding seam and the worker's eyes. The camera captures the welding area and transmits the image to the display, enabling clear observation of the welding seam while maintaining the ability to weld various vehicle models.
2Ease of operation
If the display is rotatably connected to allow position adjustment, then the display can be positioned for optimal viewing, but the electric wire may become excessively extended or tangled
Solution Approach 1:
The patent makes the display rotatably connected to the welding machine body, allowing dynamic position adjustment during welding operations. This enables the display to be positioned at different angles and orientations for optimal viewing while maintaining a compact connection through the rotatable joint.
Solution Approach 2:
The patent uses a flexible electric wire to connect the display to the power source and control system. The flexible wire can accommodate the rotational movement of the display without tangling or excessive extension, allowing position adjustment while managing wire complexity.
3Loss of information
If the camera is mounted on the electrode holder to capture welding seam, then clear observation of welding seam is enabled, but the camera and display system adds weight and complexity to the suspended welding machine
Solution Approach 1:
The patent merges the camera with the electrode holder, integrating the imaging function into the existing welding structure. This combination allows the camera to capture the welding seam while sharing the mounting structure and support system with the electrode holder, reducing overall complexity.
Solution Approach 2:
The electrode holder serves dual functions: performing the welding operation and mounting the camera for seam observation. This multi-functionality reduces the need for separate mounting structures and simplifies the overall system design while enabling clear welding seam visibility.

AI summary
The present disclosure provides a suspended-type spot welding device convenient for welding and assembling of various vehicle models, falling within the technical field of welding. A suspension frame, a rotation piece, a spot welding machine body, a first electrode holder and a second electrode holder are included. According to the present disclosure, by approaching a welding seam with a camera, a position of the welding seam is displayed by a display. Under the action of a balancing weight, a position of the display is always kept above, which is convenient for workers to know the position of the welding seam through the display at any time and avoids the display from moving with a spot welding machine body, thus facilitating the workers to weld the welding seam.
