[0002] In the welding process of the coaxial packaging lens, the accurate butt joint and stable fixation of the lens and the lens cover are the key to ensure the welding quality.

[0003] In the prior art, in order to realize the positioning of the lens, a guide assembly is often arranged around the lens. However, these guide assemblies often cannot be automatically stored or removed after the lens is preliminarily positioned. In the subsequent assembly and welding process, interference with the lens cover or the welding mechanism is likely to occur, which not only hinders the smoothness of the lens moving down to the assembly position, but also makes it difficult to dynamically adjust the suction force of the auxiliary suction cup arranged at the bottom of the lens according to the requirements of the operation stage. In the lens position fine adjustment stage, if the suction force is too strong, the flexible adjustment of the lens will be limited, resulting in increased positioning time and difficulty in ensuring the positioning accuracy.

DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0021] Example 1: like Figures 1 to 10 As shown, a coaxial encapsulation lens welding device includes a support platform 1.

[0022] The support platform 1 is equipped with several pairs of clamping components for holding the lens cover 14: A lifting electric push rod 211 is installed on the support platform 1. A positioning column 2 is installed at the output end of the lifting electric push rod 211. A guide component for the position of the guide lens 15 is rotatably installed on the positioning column 2. A sealing cover 32 is installed on the support platform 1. A piston 321 connected to the output end of the lifting electric push rod 211 is slidably arranged on the sealing cover 32. A hose 31 is installed on the side wall of the sealing cover 32. A suction cup 3 is installed at the end of the hose 31. The suction cup 3 is attached to the bottom of the lens 15. A rocker arm 27 is mounted at the rotation center of the guide assembly. A synchronous plate 26, which moves vertically in sync with the positioning column 2, is mounted on the support platform 1, and the synchronous plate 26 is slidably connected to the rocker arm 27. A positioning plate 28 with a flip groove 281 is mounted on the support platform 1, and the side wall of the synchronous plate 26 is slidably connected to the flip groove 281. During the downward assembly of the lens 15, the synchronous plate 26 drives the guide assembly to rotate and retract, and the piston 321 moves downward to increase the suction force of the suction cup 3. The lifting electric push rod 211 serves as the power source to drive the positioning column 2 to move. When the synchronous plate 26 moves with the positioning column 2, its side wall slides in the flip groove 281 of the positioning plate 28. The guide assembly is rotated through the transmission of the rocker arm 27 to achieve automatic retraction and avoid interference. At the same time, the piston 321 moves within the sealing cover 32 to change the air pressure, which is transmitted to the suction cup 3 through the hose 31 to dynamically adjust the suction force, taking into account the fine adjustment and assembly fixation requirements of the lens 15, and improving the operational flexibility and stability.

[0023] like Figures 1 to 10As shown in the specific embodiment, the bottom of the support table 1 is provided with a plurality of pairs of support legs 11, cross bars 111 are arranged between the support legs 11 on the same side, horizontal bars 112 are arranged between the support legs 11 on the two sides, guide rails 122 are arranged on the support table 1, a mechanical arm 12 is slidably arranged on the guide rails 122, a welding gun 121 is arranged at the output end of the mechanical arm 12, and the welding gun 121 is used for welding the lens 15 and the lens cover 14. The support legs 11 provide support for the whole device, the cross bars 111 enhance the connection strength of the support legs 11 on the same side through the triangular stability principle, the horizontal bars 112 enhance the integrity of the support legs 11 on the two sides, and the load-carrying capacity and stability of the support table 1 are improved together; the mechanical arm 12 can be flexibly adjusted in position by sliding along the guide rails 122, and the welding gun 121 is used for precise welding at the connection between the lens 15 and the lens cover 14, thereby expanding the welding operation range and ensuring the welding precision.

[0024] As shown in the specific embodiment, the bottom of the support table 1 is provided with a plurality of pairs of support legs 11, cross bars 111 are arranged between the support legs 11 on the same side, horizontal bars 112 are arranged between the support legs 11 on the two sides, guide rails 122 are arranged on the support table 1, a mechanical arm 12 is slidably arranged on the guide rails 122, a welding gun 121 is arranged at the output end of the mechanical arm 12, and the welding gun 121 is used for welding the lens 15 and the lens cover 14. The support legs 11 provide support for the whole device, the cross bars 111 enhance the connection strength of the support legs 11 on the same side through the triangular stability principle, the horizontal bars 112 enhance the integrity of the support legs 11 on the two sides, and the load-carrying capacity and stability of the support table 1 are improved together; the mechanical arm 12 can be flexibly adjusted in position by sliding along the guide rails 122, and the welding gun 121 is used for precise welding at the connection between the lens 15 and the lens cover 14, thereby expanding the welding operation range and ensuring the welding precision. Figures 1 to 10 Further, as shown in the specific embodiment, the clamping assembly includes a pair of clamping plates 13, the clamping plates 13 are arc-shaped, the lens cover 14 is clamped between the clamping plates 13, locking bolts 131 are arranged between the clamping plates 13, guide rods 132 are movably arranged in the side walls of the clamping plates 13, guide seats 133 are arranged at the two ends of the guide rods 132, the guide seats 133 are welded to the bottom of the support table 1, and the bottom of the support table 1 is connected with the shell of the lifting electric push rod 211. The spacing of the clamping plates 13 can be adjusted by rotating the locking bolts 131, the guide rods 132 slide in the guide seats 133 to provide guidance for the movement of the clamping plates 13, and the arc-shaped clamping plates 13 can be adapted to lens covers 14 of different specifications and stably clamped. The fixing of the guide seats 133 to the support table 1 and the connection of the support table 1 to the shell of the lifting electric push rod 211 ensure the overall stability of the clamping assembly and the lifting structure, and provide a stable foundation for subsequent assembly and welding.

[0025] Embodiment 2: Based on the above embodiment and the present embodiment, the difference is that, as shown in the specific embodiment, Figures 1 to 10As shown, the guide assembly includes a connecting plate 22. A connecting frame 21 is rotatably mounted on the sidewall of a pair of connecting plates 22. The connecting frame 21 is welded to the sidewall of the positioning post 2. A positioning rod 232 is inserted into the sidewall of the connecting plate 22. A push plate 23 is installed at the end of the positioning rod 232. A clamping electric push rod 231 is installed on the connecting plate 22. The output end of the clamping electric push rod 231 is connected to the push plate 23. A bracket 221 is installed on the connecting plate 22. A soft pad 222 is installed on the top of the bracket 221 and supports the bottom of the lens 15. The connecting frame 21 connects the connecting plate 22 to the positioning post 2, allowing the guide assembly to move with the positioning post 2 and rotate around the connecting frame 21. When the clamping electric push rod 231 pushes the push plate 23, the positioning rod 232 acts as a guide, ensuring that the push plate 23 moves smoothly. The soft pad 222 on the top of the bracket 221 directly contacts the bottom of the lens 15, providing support while avoiding hard contact that could damage the lens 15, thus achieving flexible support and initial positioning of the lens 15.

[0026] like Figures 1 to 10 As shown, in a specific embodiment, a guide block 24 is movably inserted into the side wall of the push plate 23, and the guide block 24 corresponds to the side wall of the lens 15. A slide plate 241 is installed on the side wall of the guide block 24, and a slide rod 242 is movably inserted through the slide plate 241. One end of the slide rod 242 is installed on the side wall of the push plate 23, and a slide seat 244 is installed on the other end of the slide rod 242. A compression spring 243 is sleeved on the slide rod 242, with one end of the compression spring 243 engaged with the slide seat 244 and the other end engaged with the side wall of the slide plate 241. When the guide block 24 contacts the side wall of the lens 15, the slide plate 241 slides along the slide rod 242 and compresses the spring 243. The elastic force of the compression spring 243 causes the guide block 24 to form a flexible clamp on the lens 15, which can accurately guide and position, and avoid damage to the lens 15 by clamping too tightly. The slide seat 244 fixes the slide rod 242, ensuring stable transmission of the elastic force of the compression spring 243 and improving the reliability of the guiding and positioning.

[0027] like Figures 1 to 10 As shown, further, a through groove 252 is provided on the push plate 23, and a pressure plate 25 is slidably disposed on the through groove 252. A pressure arm 251 is rotatably mounted on one end of the pressure plate 25, and the end of the pressure arm 251 is rotatably connected to the side wall of the guide block 24. The pressure arm 251 is in an inclined state. After the guide block 24 is squeezed inward by the lens 15, the pressure plate 25 moves downward through the pressure arm 251, thereby pressing the lens 15 and ensuring that the lens 15 is tightly attached to the suction cup 3. When the guide block 24 is squeezed and contracted, the inclined pressure arm 251 rotates, converting the horizontal displacement of the guide block 24 into the vertical downward movement of the pressure plate 25 along the through groove 252, thereby pressing the lens 15. This linkage structure does not require additional power. The reaction force of the lens 15 on the guide block 24 can be used to make the pressure plate 25 cooperate with the suction cup 3 to fix the lens 15, ensuring that the lens 15 does not shift during movement, simplifying the structure while improving the fixing effect.

[0028] As shown in Figures 1 to 10 Further, the side wall of the synchronization plate 26 is movably penetrated by a limiting rod 261, one end of the limiting rod 261 is installed on the side wall of the positioning column 2, the other end of the limiting rod 261 is installed on a limiting plate 262, a limiting spring 263 is sleeved on the limiting rod 261, one end of the limiting spring 263 is clamped on the limiting plate 262, the other end of the limiting spring 263 is clamped on the synchronization plate 26, an installation frame 273 is installed on the synchronization plate 26, an optical rod 272 is installed on the installation frame 273, a strip-shaped slot 271 is formed on the rocker arm 27, and the rocker arm 27 is slidably arranged in the strip-shaped slot 271. The limiting rod 261 limits the movement direction of the synchronization plate 26, the elastic force of the limiting spring 263 enables the synchronization plate 26 to move synchronously with the positioning column 2, and at the same time, provides buffering for the sliding of the synchronization plate 26 along the overturning slot 281; the optical rod 272 slides in the strip-shaped slot 271 of the rocker arm 27, converts the movement of the synchronization plate 26 into the rotation of the rocker arm 27, realizes the rotation storage of the guide assembly, and the installation frame 273 ensures that the optical rod 272 is stably installed and ensures smooth transmission.

[0029] As shown in Figures 1 to 10 Further, a vertical slot 282 is also formed on the positioning plate 28, the vertical slot 282 is connected with the overturning slot 281, the overturning slot 281 is an inclined slot, a protrusion 283 is slidably arranged on the overturning slot 281, and the protrusion 283 is installed on the side wall of the synchronization plate 26. When the synchronization plate 26 moves downward, the protrusion 283 slides along the inclined overturning slot 281, forcing the synchronization plate 26 to drive the rocker arm 27 to rotate the guide assembly; when the synchronization plate 26 moves upward, the protrusion 283 slides along the vertical slot 282, and the guide assembly is reset under the action of gravity and the limiting spring 263; the connection design of the vertical slot 282 and the overturning slot 281 realizes the automatic storage and reset of the guide assembly in different movement stages, without manual intervention, and improves the work efficiency.

[0030] Example 3: Based on the above examples, the difference between the present embodiment is: as shown in Figures 1 to 10 The bottom of the suction disc 3 is provided with four vertical rods 312, the bottom of the four vertical rods 312 is provided with a guide sleeve 311, the guide sleeve 311 is arranged outside the hose 31, and the side wall of the guide sleeve 311 is connected with the side wall of the positioning column 2. The vertical rod 312 supports the suction disc 3 and is connected with the guide sleeve 311, the guide sleeve 311 is fixed on the positioning column 2, provides guidance for the movement of the suction disc 3 with the positioning column 2, and ensures that the suction disc 3 always faces the bottom of the lens 15; at the same time, the guide sleeve 311 protects the hose 31 from external damage, ensures stable air pressure transmission, and improves the reliability of the suction disc 3.

[0031] The present application also discloses a welding method for coaxially packaging lenses, and the steps are as follows: Step one: fix the lens cover, adjust the clamping assembly's clamping plate 13 and locking bolt 131, and stably clamp the lens cover 14 on the support table 1; Step two: place and fix the lens, place the lens 15 on the soft pad 222 of the guiding assembly, start the clamping electric push rod 231, position the lens 15 through the guiding block 24, and cooperate the pressing plate 25 with the suction cup 3 to fix the lens 15; Step three: move down the lens and store the guiding assembly, start the lifting electric push rod 211, drive the positioning column 2 to move down, and synchronously rotate the guiding assembly to be stored by the synchronous plate 26, and the piston 321 moves down to enhance the suction force of the suction cup 3; Step four: welding operation, when the lens 15 is connected with the lens cover 14, the mechanical arm 12 drives the welding gun 121 to weld the connection; Step five: reset the equipment, after the welding is completed, the lifting electric push rod 211 is reset, the guiding assembly returns to the original position, and the finished product is removed for the next operation.

[0032] The implementation principle of the coaxial packaging lens welding equipment is as follows: Firstly, the lens cover 14 is fixed through the clamping assembly. A pair of arc-shaped clamping plates 13 in the clamping assembly are guided by the guide rod 132 and the guide base 133, and the locking bolt 131 is adjusted to adapt to lens covers 14 of different specifications, so that the lens cover 14 is stably clamped on the support table 1, thereby providing a stable basis for subsequent welding. Through the adjustable clamping structure, the reliability of fixing the lens cover 14 is ensured, and the compatibility of different specifications of the lens cover 14 is realized, thereby improving the application range of the equipment.

[0033] Subsequently, the lens 15 is placed on the guiding assembly. The bracket 221 in the guiding assembly is provided with the soft pad 222 on the top, which can gently support the bottom of the lens 15 and avoid damaging the lens 15. The clamping electric push rod 231 is started to drive the push plate 23 and the positioning rod 232 to move, so that the guiding block 24 is in contact with the side wall of the lens 15. Since the guiding block 24 is connected with the push plate 23 through the sliding plate 241, the sliding rod 242 and the compression spring 243, the elastic action of the compression spring 243 can provide a buffer for the lens 15, prevent the lens 15 from being damaged due to clamping too tightly, and realize the preliminary guiding and positioning of the lens 15.

[0034] At the same time, when the guiding block 24 is pressed inward and shrinks, the pressing arm 251 is driven to rotate, the pressing plate 25 moves downward along the through slot 252 on the push plate 23, the lens 15 is tightly pressed on the suction cup 3, and the suction force of the suction cup 3 is cooperated to ensure that the lens 15 will not deviate or fall off during movement. Through the multiple buffering and fixing structures in this link, the lens 15 can be accurately positioned and effectively protected from damage, thereby ensuring the stability of the lens 15 during subsequent movement.

[0035] Next, the lifting electric push rod 211 starts to drive the positioning column 2 to move downward. When the positioning column 2 moves downward, the synchronous plate 26 moves vertically synchronously, and the protrusion 283 on the side wall of the synchronous plate 26 slides in the flip groove 281 (inclined groove) of the positioning plate 28. Through the sliding connection of the rocker arm 27 and the synchronous plate 26 (the strip-shaped groove 271 on the rocker arm 27 cooperates with the light rod 272 on the synchronous plate 26), the guiding assembly is driven to rotate around the connecting frame 21, realizing the rotary storage of the guiding assembly, avoiding interference with the lens cover 14 during the assembly of the lens 15 moving downward, and ensuring that the lens 15 can smoothly approach the lens cover 14. This design realizes the automatic storage of the guiding assembly through the linkage of the mechanical structure, ingeniously solves the interference problem between components, and ensures the smoothness of the lens 15 assembly process.

[0036] At the same time that the positioning column 2 moves downward, the piston 321 connected with the positioning column 2 moves downward synchronously in the sealing cover 32, so that the internal pressure of the sealing cover 32 changes, the pressure is transmitted to the suction cup 3 through the hose 31, and the adsorption force of the suction cup 3 on the lens 15 is further enhanced, ensuring the stability of the lens 15 during assembly. When the lens 15 moves downward to the position accurately connected with the lens cover 14, the lifting electric push rod 211 stops moving, at this time the mechanical arm 12 moves along the guide rail 122 on the support table 1, driving the welding gun 121 to reach the welding position to perform welding work on the connection between the lens 15 and the lens cover 14. This process synchronously enhances the adsorption force by using the change of air pressure, and cooperates with the precise movement of the mechanical arm 12, which not only ensures the stability of the lens 15 during assembly, but also ensures the accuracy of the welding position, and improves the welding quality.

[0037] After welding, the lifting electric push rod 211 resets to drive the positioning column 2 and the synchronous plate 26 to move upward, and the protrusion 283 on the synchronous plate 26 slides along the vertical groove 282 of the positioning plate 28. The guiding assembly is restored to its original position under the drive of the rocker arm 27, so as to place and assemble the lens 15 next time. During the whole process, the support legs 11 at the bottom of the support table 1 enhance the stability of the overall structure through the cross ribs 111 and horizontal ribs 112, and the cooperation of the mechanical arm 12 and the welding gun 121 ensures the accuracy of welding, and the components work cooperatively to realize efficient and stable packaging and welding of the lens 15 and the lens cover 14. The equipment not only facilitates continuous operation, but also can maintain high-precision welding effect for a long time through the orderly resetting of each component and the stable design of the overall structure, improving the production efficiency and product quality.
