Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal part welding, and particularly relates to a welding device for sheet metal part assembly. Background Art

[0002] Sheet metal parts are products processed by sheet metal technology. Sheet metal is a comprehensive cold processing technology for metal sheets (usually below 6 mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as automobile bodies), etc. Products processed by sheet metal technology are called sheet metal parts, and these products have the characteristics of light weight, high strength, electrical conductivity (able to be used for electromagnetic shielding), low cost, good mass production performance, etc. Sheet metal parts are widely used in the fields of electronic appliances, communication, automotive industry, medical devices, etc. For example, in electronic products such as computer cases, mobile phones, and MP3 players, sheet metal parts are essential components. Welding is a process of connecting two or more metal parts by melting the metal. During the assembly of sheet metal parts, welding can provide very strong connection strength to ensure the stability between various parts, thereby meeting the mechanical requirements during product use.

[0003] When some existing sheet metal part welding devices are in use, they can only clamp and fix the sheet metal parts, lacking a mechanism for flipping the sheet metal parts, and unable to flip and change the surface of the sheet metal parts. Therefore, it is not convenient to perform double-sided welding on the sheet metal parts.

[0004] For example, a welding device for sheet metal parts disclosed in the patent with the publication number CN220993331U. The welding device of this patent works through a cylinder to pull the moving plate, so that the moving plate moves on the slot holes, driving the bottom plate to move. When moving, through the cooperation of the slider and the slide rail, the moving plate will drive the bottom plate to move together, thereby driving the clamping plate to move, causing the clamping plate to move closer to the object until the object is clamped. Finally, the welding assembly can perform welding work on the clamped object. This welding device can not only control the movement of the clamping plate through the cylinder to complete the rapid automatic clamping of the object, which is more time-saving and labor-saving and has the effect of improving the clamping efficiency, but also the driving end of the clamping assembly is located below the welding platform, which has the effect of reducing the space occupied by the clamping assembly on the welding surface of the welding platform, making it easier to place the object and not easy to collide with the driving end, being safer and improving the practicability.

[0005] Although the above-mentioned welding device has the advantages of rapid automatic clamping, improving the clamping efficiency, and reducing the space occupation of the welding platform, etc., it does have obvious limitations when dealing with sheet metal parts that need to be flipped and welded on both sides. The device does not have a mechanism designed for flipping the sheet metal parts. Therefore, when there is more than one surface of the sheet metal part that needs to be welded, the user must manually remove the welded sheet metal part from the device, flip it, and then re-clamp it. This not only increases the operation complexity but also reduces the overall welding efficiency.

[0006] Therefore, it is necessary to invent a welding device for sheet metal assembly to solve the above problems. Utility Model Content

[0007] The purpose of the present utility model is to provide a welding device for sheet metal assembly to solve the problems in the above technology.

[0009] The loading mechanism is stably supported by the fixed columns, ensuring the stability and safety during the welding process.

[0010] Preferably, moving rollers are installed at both ends of the clamping groove, guiding sliding grooves are opened on both sides of the inner wall of the loading frame, and the moving rollers are slidably connected with the guiding sliding grooves.

[0011] The cooperation between the moving rollers and the guiding sliding grooves makes the clamping groove move more smoothly during the movement, reducing friction and vibration and improving the smoothness of the clamping groove during movement.

[0012] Preferably, a vacuum chuck is arranged on the top of the base plate, and the vacuum chuck is located directly below the loading mechanism.

[0013] The vacuum chuck can firmly adsorb the sheet metal parts, ensuring that the sheet metal parts will not shift or fall off during the welding process, improving the accuracy and stability of welding.

[0014] Preferably, a vacuum pump is installed on the top of the base plate, the vacuum pump is located below the vacuum chuck, and the vacuum pump is connected to the vacuum chuck through an air pipeline.

[0015] By generating negative pressure with the vacuum pump, the vacuum chuck can effectively adsorb the sheet metal parts. This automated adsorption method improves work efficiency and reduces the complexity of manual operation.

[0016] Preferably, a third electric push rod and a telescopic rod are installed on the top of the base plate, and the working end of the third electric push rod and the top end of the telescopic rod are both fixedly connected to the bottom of the vacuum suction cup.

[0018] Preferably, the number of the telescopic rods is set to four, and the four telescopic rods are respectively located at the four corners of the bottom of the vacuum suction cup.

[0019] The four telescopic rods are respectively located at the four corners of the bottom of the vacuum suction cup. This layout provides uniform supporting force and ensures the stability of the sheet metal part during lifting and welding.

[0020] Preferably, a fixed bracket is installed on the top of the base plate. One end of the fixed bracket extends above the loading mechanism, and a linear slide table module is installed at the bottom of the end of the fixed bracket that extends above the loading mechanism.

[0021] The fixed bracket provides a stable installation foundation for the linear slide table module, and the linear slide table module can accurately control the movement trajectory of the welding component, realizing precise positioning of the welding position.

[0022] Preferably, a fourth electric push rod is installed at the bottom of the slide of the linear slide table module, and a welding component is installed at the working end of the fourth electric push rod.

[0023] The fourth electric push rod can push the welding component down to the position where it contacts the sheet metal part and provide stable pressure during the welding process. This design makes the welding process more automated and efficient.

[0024] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0025] 1. By setting up a loading mechanism to load and fix the sheet metal part, through the transmission connection between the driving motor and the loading mechanism, the equipment can easily realize the overall flipping of the loading mechanism and the sheet metal part clamped thereon. This design greatly simplifies the turning-over process of the sheet metal part, eliminating the need for manual intervention or complex mechanical operations, and improving the efficiency and accuracy of turning over.

[0026] 2. The loading mechanism drives the clamping groove to approach the sheet metal part through the first electric push rod, and uses the second electric push rod to push the limiting clamping plate to clamp the sheet metal part. This design enables the loading mechanism to flexibly adapt to sheet metal parts of different sizes and shapes, realizing precise clamping and positioning. BRIEF DESCRIPTION OF THE DRAWINGS
