Description

Technical Field

[0001] The invention relates to the technical field of mobile phone frame processing, and in particular to a laser welding jig for mobile phone frame processing. Background Art

[0002] With the continuous development of smart phones, the competition in the smart phone sales market has become increasingly fierce. The appearance of the mobile phone has become one of the considerations for consumers to choose. As a part of the appearance of the mobile phone, the mobile phone frame requires that the welding process can achieve high-precision welding during the processing of the mobile phone frame to ensure the perfect combination of the frame. A laser welding fixture for processing a mobile phone frame is an auxiliary tool specially used in the laser welding process of the mobile phone frame.

[0003] An existing laser welding jig for processing a mobile phone frame has a base with a groove of a specific shape for placing the mobile phone frame, whose size is adapted to the mobile phone frame, providing preliminary positioning and support for the frame. After the upper cover is buckled with the base, a closed space is formed to fix the mobile phone frame therein. The upper cover is provided with a through groove that penetrates the cover body so that the welding laser can be injected for welding operation;

[0004] As for the existing laser welding jig for processing mobile phone frames, firstly, different models of mobile phone frames have differences in size, shape, structure, etc. Some existing jigs are often only suitable for specific models of mobile phone frames. For mobile phone manufacturers, they need to equip different models of mobile phone frames with different jigs, which increases production costs and management difficulties. Secondly, after welding, the jig and the mobile phone frame need to be cooled in time, and the traditional heat dissipation method requires a long heat dissipation time, which affects production efficiency. Finally, when fixing the mobile phone frame, the clamping force is applied by tightening screws or spring clips, and the clamping force will be unevenly distributed in different parts of the mobile phone frame. The manually operated clamping device requires the operator to spend time and energy to tighten the screws or adjust the position of the clips each time the mobile phone frame is fixed. This not only increases the complexity of the operation, but also reduces production efficiency. Summary of the invention

The bottom plates 301 serve as the main body for fixing the mobile phone frame in the longitudinal direction, and the frame grooves 302 provided fit the shape of the mobile phone frame. When the mobile phone frame is placed therein, it can fit the shape of the mobile phone frame to the greatest extent, provide stable and accurate longitudinal positioning for the mobile phone frame, and effectively prevent the mobile phone frame from longitudinal displacement during the processing.

[0037] Please refer to the attached Figure 1 and attached Figure 7 -Attached Figure 8The elastic mechanism 6 includes an airbag 601. The bottom of the protrusion 304 in the fixing mechanism 3 and the frame groove 302 are both provided with airbags 601. The airbag 601 is provided with an anti-leakage plug 603 and an input port 602. The input port 602 is provided with a filling component. When the airbag 601 contacts the mobile phone frame, it can use its own elasticity to buffer the pressure, so that the mobile phone frame is protected from possible damage caused by hard contact during the fixing process. At the same time, the airbag 601 can better fit the shape of the mobile phone frame. When the airbag 601 does not need to be inflated or deflated, the anti-leakage plug 603 can tightly seal the airbag 601 to prevent gas leakage, and the input port 602 can inflate the airbag 601;

[0038] The filling assembly includes a catheter 604, one end of which is fixedly connected to the input port 602, the other end of the catheter 604 is fixedly connected to a shunt tube 606, and the remaining end of the shunt tube 606 is fixedly connected to the output end of a micro air pump 605.

The shunt tube 606 can evenly distribute the gas from the micro air pump 605 to each catheter 604 and input it into the airbag 601 through the catheter 604.

[0039] Please refer to the attached Figure 1 -Attached Figure 4 , the rear end of the mounting plate 1 is detachably connected to a mechanical arm 7, the bottom end of the mechanical arm 7 is fixedly connected to a base 8, a rotating assembly and a height adjustment assembly are arranged on the mechanical arm 7, the rotating assembly includes a rotating cabin 701, a rotating cabin 701 is arranged at the middle of the top of the base 8, a rotating motor 702 is arranged in the rotating cabin 701, the output end of the rotating motor 702 is fixedly connected to a rotating table 703, the height adjustment assembly includes a second motor 704, the bottom end of the second motor 704 is fixedly connected to the top of the rotating table 703 in the rotating assembly, the output end of the second motor 704 is fixedly connected to one end of a first connecting arm 705, one of the first A third motor 706 is provided at the other end of the connecting arm 705, and the output end of the third motor 706 is fixedly connected to one end of the second connecting arm 707. The other end of the second connecting arm 707 is detachably connected to the mounting plate 1. The rotating cabin 701 serves as the installation place of the rotating motor 702 and protects the rotating motor 702. The rotating motor 702 provides power for the overall rotation of the robotic arm 7. The second motor 704 and the third motor 706 provide power for the rotation of the first connecting arm 705 and the second connecting arm 707. After the rotation, the first connecting arm 705 and the second connecting arm 707 can extend the robotic arm 7.

[0040] Working principle: start the adjustment motor 206 in the adjustment power cabin 203, the adjustment motor 206 makes the adjustment rotating block rotate, and the rotating adjustment rotating block can make the sliding clamp 202 slide on the slider 201 under the connection action of the rotating connecting block 205 and the pin. When the fixed plate on the adjacent side of the sliding clamp 202 reaches the width of the processed mobile phone frame, disconnect the adjustment motor 206, and then rotate the rotating shaft 305. At this time, the coil spring 307 is stretched, and the top plate 303 is opened under the connection of the connecting piece 308, and then the mobile phone frame is placed in it. After loosening the top plate 303, the coil spring 307 restores its original shape, and the released elastic potential energy makes the top plate 303 reset. After the reset, the convex block 304 at the bottom of the top plate 303 presses against the mobile phone frame, and then start the micro air pump 605. The output end of the air pump pumps air to the shunt pipe 606, and then the air is input from the input port 602 to the airbag 601 through the conduit 604 on the shunt pipe 606. In the process, the airbag 601 is inflated, and the inflated airbag 601 contacts and fits with the mobile phone frame. The pressure generated by the expansion of the airbag 601 is used to fix the object between the bottom plate 301 and the top plate 303. Then, the rotating motor 702, the second motor 704 and the third motor 706 in the rotating cabin 701 are started, so that the mechanical arm 7 extends and rotates, so that the direction and angle of the mounting plate 1 change to reach the best welding position. Then, the laser is used to weld the mobile phone frame. After the mobile phone frame is welded, the temperature of the bottom plate 301 and the top plate 303 increases, and the temperature of the bottom plate 301 and the mobile phone frame is transferred to the heat-conducting metal tube 401. Then, the heat-conducting metal tube 401 transfers the temperature to the heat-dissipating fins 402. After the fan 502 on the mounting platform 501 is started, the contact area with the air is increased through the heat-dissipating fins 402 and the air circulation speed is accelerated by the fan 502, so that the bottom plate 301 and the mobile phone frame are cooled quickly. When they need to be removed after the welding is completed, the anti-leakage plug 603 is opened. The air in the airbag 601 is released, and the top plate 303 is rotated again to open the top plate 303, and the frame of the mobile phone can be taken out.
