Description

Technical Field

[0001] This utility model relates to the field of jewelry processing, specifically to an earring welding device. Background Technology

[0002] Earrings typically consist of two parts: the ear post and the decorative piece. The ear post passes through the wearer's ear piercing, while the decorative piece is attached to the base of the post for aesthetic purposes. The manufacturing process of earrings primarily relies on welding, which is currently mostly done manually. Production workers first obtain the ear post and the decorative piece, accurately attaching the end of the ear post to the welding point on the decorative piece, and then using a welding torch to weld the two together.

[0003] However, due to the extremely small dimensions of earring posts and jewelry, especially the pointed tip of the earring post to be welded, attaching one end of the earring post to the jewelry often requires production workers to concentrate intently for extended periods, resulting in significant energy expenditure, low production efficiency, and difficulty in achieving accurate positioning. Furthermore, during the welding process, since the earring post and jewelry are positioned manually, the bright sparks generated during welding can affect the production workers, causing slippage and misalignment between the earring post and the jewelry, leading to inaccurate welding points, product defects, rework, or defective products. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an earring welding device that can solve the problems of high labor consumption, low production efficiency, and easy quality defects in existing earring welding processes.

[0005] This utility model is achieved through the following technical solution:

[0006] An earring welding device includes: a feeding module for feeding earrings; a clamping module including: a clamping jaw, a clamping jaw lifting drive mechanism, and a clamping jaw horizontal drive mechanism; the clamping jaw is fixed to the clamping jaw lifting drive mechanism, and the clamping jaw lifting drive mechanism is fixed to the clamping jaw horizontal drive mechanism; a soldering powder dipping station, on which soldering powder is spread; a first welding torch for preheating the earring, the first welding torch being disposed on one side of the soldering powder dipping station; a first welding torch drive mechanism for driving the first welding torch closer to or away from the soldering powder dipping station; a welding platform having a plurality of welding stations, each welding station having a cavity for accommodating jewelry; a second welding torch for welding and fixing, the second welding torch being disposed on one side of the welding platform; a second welding torch drive mechanism for driving the second welding torch closer to or away from the welding platform; the feeding module, the soldering powder dipping station, and the welding platform are disposed in the same horizontal direction.

[0008] Furthermore, the earring welding equipment also includes: a horizontal drive mechanism for the welding platform; the horizontal drive mechanism for the welding platform is a linear guide rail module, and the welding platform is fixed on the slider of the linear guide rail module to switch different welding positions to the area below the gripper.

[0009] Furthermore, the gripper lifting drive mechanism is a linear guide rail module, and the gripper part is fixed to the slider of the gripper lifting drive mechanism via a gripper mounting plate; the gripper horizontal drive mechanism is a linear guide rail module, and the guide rail of the gripper lifting drive mechanism is fixed to the slider of the gripper horizontal drive mechanism.

[0010] Furthermore, the feeding module includes: a vibrating screen and a feeding track; a spiral conveying channel is arranged around the vibrating screen, and one end of the feeding track is connected to the end of the spiral conveying channel.

[0016] Compared with existing technologies, the beneficial effects that this utility model can achieve are as follows:

[0017] During operation, the feeding module continuously feeds earring post material. The clamping module, through the coordinated action of the horizontal and vertical driving mechanisms of the clamping jaws, moves the jaws to the feeding module to pick up the earring post and place it on the soldering powder dipping platform. The first welding torch moves towards the earring post to heat it (preheat). After preheating, the jaws carry the earring post to the soldering powder dipping platform to pick up solder powder, and then move the earring post to the welding platform, so that the earring post is attached to the point to be welded on the jewelry, achieving accurate positioning between the earring post and the jewelry.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] This utility model discloses an earring welding device for the earring welding process, specifically, for welding and fixing earring posts and jewelry together to obtain finished earrings.

[0030] See Figures 1-5 This utility model includes: a feeding module 10, a clamping module 20, a soldering powder dipping station 30, a first welding torch 40, a first welding torch drive mechanism 50, a welding platform 60, a second welding torch 70, and a second welding torch drive mechanism 80. The feeding module 10 is used to feed the earrings. (See reference...) Figure 4The clamping module 20 specifically includes a gripper portion 21, a gripper lifting drive mechanism 22 for driving the gripper portion 21 to move up and down, and a gripper horizontal drive mechanism 23 for driving the gripper portion 21 to move horizontally. The gripper portion 21 is fixedly mounted on the gripper lifting drive mechanism 22, and the gripper lifting drive mechanism 22 is fixedly mounted on the gripper horizontal drive mechanism 23. The surface of the soldering powder table 30 is covered with soldering powder. A first welding torch 40 is used to preheat the earring post before welding. The first welding torch 40 is located on one side of the soldering powder table 30, and a first welding torch drive mechanism 50 is used to drive the first welding torch 40 closer to or further away from the soldering powder table 30. The welding platform 60 has several welding stations, each with a cavity for accommodating jewelry. The jewelry is accommodated in each welding station. A second welding torch 70 is used to weld and fix the earring post and jewelry. The second welding torch 70 is located on one side of the welding platform 60, and a second welding torch drive mechanism 80 is used to drive the second welding torch 70 closer to or further away from the welding platform 60. Among them, see Figure 5 The feeding module 10, the welding powder dipping station 30, and the welding platform 60 are arranged in the same horizontal direction, so that the gripper horizontal drive mechanism 23 can drive the gripper part 21 to move between the feeding module 10, the welding powder dipping station 30, and the welding platform 60.

[0031] During operation, the feeding module 10 continuously feeds earrings. The clamping module 20, through the coordinated action of the jaw horizontal drive mechanism 23 and the jaw lifting drive mechanism 22, moves the jaw part 21 to the feeding module 10 to clamp the earring. The earring is then placed on the soldering powder table 30. The first welding torch 40 moves towards the earring to heat (preheat) it. After preheating, the jaw part 21 moves the earring to dip it in soldering powder on the soldering powder table 30, then moves it onto the welding platform 60, aligning it with the point on the jewelry to be welded, achieving accurate positioning between the earring and the jewelry. The second welding torch 70 moves towards the welding point and welds the earring and jewelry together. After welding, the jaw part 21 clamps the finished earring and transports it to the unloading area, completing the welding process.

It always keeps the welding point position accurate, ensures the welding quality, and significantly improves the yield rate. (3) A double welding gun structure (including the first welding gun 40 and the second welding gun 70) is adopted. The earring post is preheated, dipped in welding powder and welded and fixed in sequence to achieve stable and good welding quality.

[0037] Preferably, the present invention also includes a workbench 100, on which the feeding module 10, the welding powder dipping station 30 and the welding platform 60 are all arranged, and the gripper horizontal drive mechanism 23 is fixedly installed on the workbench 100.

[0038] Preferably, the first welding torch drive mechanism 50 is also a linear guide rail module, and the first welding torch 40 is fixedly connected to the slider of the first welding torch drive mechanism 50.

[0039] Similarly, the second welding torch drive mechanism 80 is also a linear guide rail module, and the second welding torch 70 is fixedly connected to the slider of the second welding torch drive mechanism 80.
