[0002] With the rapid development of the 3C industry, the welding technology for accessories in mobile phones and other electronic products is becoming increasingly important. While traditional welding techniques are mature, they often struggle to meet the growing production capacity and welding quality requirements when dealing with products with complex structures. This is especially true in mobile phone accessory welding, where the complexity of the product structure necessitates welding auxiliary parts on very small support surfaces. Furthermore, these parts must be suspended above the product's welding surface during welding, with only a small portion of the surface being welded contacting the product. Traditional semi-automatic welding methods rely on manual placement of welding auxiliary parts, which is not only inefficient but also inefficient and labor-intensive, failing to meet the demands of large-scale production.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown, a suspended non-planar welding device includes a carrier transfer device 1, which comprises an electric cylinder 13 and a fixture 11. The fixture 11 is driven by the electric cylinder 13 to move between a loading position 14 and a welding position. The fixture 11 is equipped with product positioning pins 12. The carrier transfer device 1 is located in the middle of the device body 4 and comprises two key structural components: the fixture 11 and the electric cylinder 13. The electric cylinder 13 is installed below the fixture 11, and the two are fixedly connected by bolts to form a stable driving connection. The electric cylinder 13, as a power source, can drive the fixture 11 to move linearly back and forth between the loading position 14 and the welding position in the middle of the device body 4 along a preset guide path. Product positioning pins 12 are vertically arranged on the surface of the fixture 11. These product positioning pins 12 are used to accurately position the product to be welded, ensuring the accuracy of the product's position during the transfer and welding process.

[0026] The auxiliary material carrier tilting device 2 includes a tilting drive mechanism 22 and an auxiliary material carrier 21. The auxiliary material carrier 21 is tilted 180° via the tilting drive mechanism 22. A positioning pin movable cylinder 24 is installed above the auxiliary material carrier 21. The auxiliary material carrier 21 is equipped with an auxiliary material positioning pin 23 and a vacuum suction hole 26. A spring 25 is installed next to the auxiliary material positioning pin 23. The tilting drive mechanism 22 is fixedly installed on the outer wall of the device body 4 and is movably connected to the auxiliary material carrier 21 installed above the device body 4 via a rotating shaft, thereby realizing the drive control of the auxiliary material carrier 21. Under the action of the tilting drive mechanism 22, the auxiliary material carrier 21 can achieve a 180° tilting action in the space above the device body 4. The positioning pin movable cylinder 24 is installed above the auxiliary material carrier 21. The output end of the cylinder is connected to the transmission structure inside the auxiliary material carrier 21, which can control the extension and retraction of the auxiliary material positioning pin 23. The surface of the auxiliary material carrier 21 is provided with auxiliary material positioning pins 23 and vacuum adsorption holes 26. The auxiliary material positioning pins 23 are used to perform preliminary positioning of the auxiliary material. A spring 25 is installed on its side. One end of the spring 25 is fixed on the auxiliary material carrier 21, and the other end is movably connected to the auxiliary material positioning pins 23, providing elastic buffering and reset function for the auxiliary material positioning pins 23, ensuring the stability and reliability of the auxiliary material positioning.

[0027] The auxiliary material carrier lifting device 3 includes a lifting motor 31, a circular gear 32, a linear gear 33, and a track 34. The auxiliary material carrier 21 is lifted and lowered along the track 34 through the meshing transmission of the circular gear 32 and the linear gear 33. The lifting motor 31 is located below the auxiliary material carrier 21 and is connected to the central shaft of the circular gear 32 through a transmission belt or coupling, providing power to the entire lifting mechanism. The circular gear 32 is installed on the other side of the device body 4. The linear gear 33 meshes with the circular gear 32 and can move linearly along the track 34 located between the linear gear 33 and the inner wall of the device body 4. The auxiliary material carrier 21 is fixedly connected to the linear gear 33, so that when the lifting motor 31 drives the circular gear 32 to rotate, the meshing transmission of the circular gear 32 and the linear gear 33 drives the auxiliary material carrier 21 to achieve stable lifting and lowering movement along the track 34.

[0028] In one embodiment of this utility model, there are two product positioning pins 12 and two auxiliary material positioning pins 23, symmetrically arranged on the fixture 11 and the auxiliary material carrier 21. The two symmetrically arranged product positioning pins 12 can establish a clear positioning reference on the fixture 11. For example, in the assembly fixture 11 of electronic products, when the product is placed on the fixture 11, the accurate position of the product on the fixture 11 can be quickly determined by cooperating with the two positioning pins, ensuring that subsequent processing, assembly and other operations are based on this precise position reference. As for the auxiliary material positioning pins 23, two are symmetrically arranged on the auxiliary material carrier 21 to prevent the auxiliary material from shifting or misaligning on the carrier. For example, in garment processing, auxiliary materials such as buttons and zippers can be accurately positioned at a specific position on the auxiliary material carrier 21 by cooperating with the auxiliary material positioning pins 23, ensuring that the auxiliary material is accurately aligned with the main material in subsequent sewing and other processes.

[0029] like Figure 1 and Figure 6 As shown, the auxiliary material positioning pin 23 is mounted on the auxiliary material carrier 21 via a positioning pin movable cylinder 24. The positioning pin movable cylinder 24 is linked and controlled by the lifting motor 31. The positioning pin movable cylinder 24 can precisely control the movement of the auxiliary material positioning pin 23, enabling it to accurately insert into or contact the auxiliary material, achieving high-precision positioning. When linked and controlled with the lifting motor 31, the height of the positioning pin can be flexibly adjusted according to the height and position requirements of different auxiliary materials to ensure positioning accuracy.

[0030] Furthermore, the carrier transfer device 1 also includes a material presence sensor, which is electrically connected to the electric cylinder 13. The material presence sensor can detect in real time whether there is material on the carrier. When the carrier is empty, the sensor transmits a signal to the electric cylinder 13, and the electric cylinder 13 will not start, thus avoiding the equipment from running without load, reducing energy waste, and reducing the risk of wear and failure that may occur due to no-load operation, thereby extending the service life of the equipment.

[0031] like Figure 1 As shown, the lifting device is equipped with a position sensor 35; the position sensor 35 can quickly and accurately detect the position of the lifting device, allowing the equipment to stop immediately after reaching the target position, without manual intervention or long waiting times. This greatly shortens the operating cycle of the lifting device and improves production efficiency.

[0032] Furthermore, the flipping drive mechanism 22 is a rotary motor, which is fixedly connected to the auxiliary material carrier 21.

[0033] In one embodiment of this utility model, a welding machine is also included, which is positioned directly above the welding position. The auxiliary material carrier 21 has a clearance surface 27 corresponding to the welding machine. The clearance surface 27 on the auxiliary material carrier 21 provides sufficient space for the welding machine, preventing collisions between the welding machine and the auxiliary materials during the welding process. On automated welding production lines, the equipment operates at high speeds. Without the clearance surface 27, the welding machine may collide with the auxiliary materials during movement or operation, causing damage to the welding machine or the auxiliary materials, increasing maintenance costs and downtime.

[0034] Working principle: The product to be welded is placed on the fixture 11 of the carrier transfer structure and moved to the loading position 14 by the electric cylinder 13; the auxiliary parts are placed on the carrier platform of the auxiliary parts carrier flipping structure and precisely positioned by the positioning pin, while the vacuum adsorption system is activated to adsorb the auxiliary parts; after the sensor detects that the auxiliary parts have been loaded, the auxiliary parts carrier flipping structure flips 180° so that the auxiliary parts face the product to be welded; the carrier transfer structure moves the product to the welding position; the auxiliary parts carrier lifting structure lowers the auxiliary parts to the position to be welded, and the position of the auxiliary parts is adjusted by the spring 25 adjustment device to adapt to different welding surfaces; the electric welding machine starts welding from directly above, and after welding is completed, the vacuum adsorption system is turned off and the auxiliary parts carrier is raised; the carrier transfer structure moves the welded product to the unloading position, completing the entire welding process.

[0035] In summary, this suspended non-surface welding device replaces manual feeding and semi-automatic operation, reducing labor costs and improving production efficiency; through vacuum adsorption and dual positioning pin design, it ensures that the positioning accuracy of auxiliary parts is ≤0.1mm, solving the welding problem of small support surfaces.
