Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dispensing technology, specifically relating to a dispensing device for gemstone inlay in precious metal jewelry. Background Technology
[0002] In the gem setting process of precious metal jewelry, the glue application process is a key step to ensure a stable connection between the gemstone and the precious metal base. The efficiency and precision of the glue application directly affect the production quality and mass production capacity of the jewelry. As the styles of precious metal jewelry become increasingly diversified, multiple gemstone setting points are often required on the same piece of jewelry. Moreover, the shapes and specifications of the jewelry vary significantly, which places higher demands on the adaptability and work efficiency of the glue application device.
[0003] Currently, various automated or semi-automated devices have emerged in the field of gemstone setting and dispensing for precious metal jewelry. Related technologies are gradually developing towards precise positioning and convenient operation. For example, some devices achieve stable clamping of jewelry by setting positioning structures to avoid displacement during dispensing affecting accuracy; other devices use three-axis modules to drive the dispensing head, and cooperate with the transmission belt to transport jewelry templates to achieve orderly dispensing operations. At the same time, the adjustment function of dispensing equipment has also been optimized to a certain extent. For example, some dispensing machine nozzles can achieve bidirectional displacement adjustment through longitudinal lead screws and transverse guide rails to adapt to the dispensing needs of different products.
[0004] However, existing technologies still have significant limitations. Most existing dispensing devices use a single dispensing head design, requiring the movement of the dispensing head or workpiece to sequentially complete dispensing operations at multiple points. Even some dual-station linkage mechanisms mainly focus on the coordination of material handling and dispensing processes, rather than the synchronous operation of multiple dispensing positions on the same workpiece. This mode results in low dispensing efficiency and cannot meet the efficiency improvement requirements of mass production scenarios. Furthermore, precious metal jewelry has complex shapes and large variations in specifications, and the distribution and spacing of dispensing positions vary among different pieces. Existing adjustment mechanisms are mostly limited to displacement adjustment in a single direction, or the adjustment operation is cumbersome, requiring manual calibration after stopping the machine. It is difficult to quickly and accurately adapt to the dispensing position requirements of jewelry with different shapes and specifications, which not only reduces production continuity but also easily affects dispensing accuracy due to adjustment errors.
[0005] In summary, existing dispensing devices for precious metal jewelry gemstone inlay have shortcomings in terms of efficiency in simultaneous multi-position operation and flexibility in adapting to multiple specifications, which restricts the improvement of production efficiency and product qualification rate. Therefore, developing a dispensing device that can achieve simultaneous multi-position dispensing and whose dispensing head position can be flexibly adjusted has become an urgent technical problem to be solved in this field.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0025] like Figures 1-4 As shown, a gemstone setting adhesive device for precious metal jewelry includes a mounting frame 1, an assembly frame 2 mounted on the bottom of the mounting frame 1, and an adhesive guide tube 3 mounted on the side of the assembly frame 2 for supplying adhesive. An adhesive guide head 4 is located on the side of the adhesive guide tube 3 near the assembly frame 2 for conveying adhesive. Multiple dispensing heads 6 are mounted inside the assembly frame 2, and a connecting tube 5 is mounted on the outer side of each dispensing head 6. Multiple connecting tubes are mounted on the adhesive guide head 4, and each connecting tube 5 is connected to a connecting tube on the adhesive guide head 4. When dispensing adhesive onto precious metals, multiple dispensing heads 6 simultaneously deliver adhesive, achieving synchronous dispensing and improving dispensing efficiency. The number of connecting tubes is greater than the number of connecting pipes 5. This arrangement allows for the assembly of more dispensing heads 6 and connecting pipes 5 onto the connecting tubes when there are many dispensing locations on precious metals, thereby enhancing the applicability of the device. Each connecting tube is equipped with a solenoid valve, which can be used to close unused connecting tubes and prevent adhesive leakage at those locations.
[0026] A positioning structure is installed between the dispensing head 6 and the assembly frame 2.
[0027] See attached document Figure 2 The positioning structure includes multiple first electromagnets 11, which are evenly arranged on the top of the inner side of the assembly frame 2. Multiple dispensing heads 6 are each fixed with an adsorption magnet 7, which is adsorbed into the first electromagnets 11. When dispensing precious metals of different shapes and specifications, the adsorption magnets 7 on the multiple dispensing heads 6 can be adsorbed onto the first electromagnets 11 at different positions, thus enabling dispensing of precious metals of different shapes and specifications. An mounting plate 8 is installed at the bottom of the assembly frame 2. The mounting plate 8 has multiple through holes 9, through which the multiple dispensing heads 6 pass and extend to the bottom of the mounting plate 8. The mounting plate 8 allows for further positioning of the dispensing heads 6 via the through holes 9, ensuring that the position of the dispensing heads 6 does not deviate. Multiple mounting plates 8 can be installed, with the through holes 9 on each plate located at different positions, thus enabling positioning of the dispensing heads 6 when dispensing different precious metals at different locations.
[0028] See attached document Figure 4 A magnetic post 12 is installed on the top of the mounting plate 8, and a second electromagnet 13 is installed on the top of the inner side of the assembly frame 2. The magnetic post 12 is inserted into and attracted to the second electromagnet 13. By setting the magnetic post 12, the mounting plate 8 can be attracted to the second electromagnet 13 after it is installed on the assembly frame 2, thereby achieving the positioning of the mounting plate 8 and avoiding deviation in the installation of the mounting plate 8.
[0029] See attached document Figures 2-3 An abutment block 10 is fixed to the outside of the dispensing head 6, and the abutment block 10 is set on the top of the mounting plate 8. The diameter of the abutment block 10 can be larger than the inner diameter of the through hole 9. With this setting, after the mounting plate 8 is installed on the assembly frame 2, the top and bottom of the mounting plate 8 can be at the bottom of the abutment block 10, thereby supporting the abutment block 10 and the dispensing head 6, avoiding the risk of the dispensing head 6 and the adsorption magnet 7 not being firmly attached to the first electromagnet 11 and falling off.
[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
