Description
Technical Field
[0001] This utility model relates to the field of automation equipment technology, and in particular to a welding device for eyeglasses and pipes. Background Technology
[0002] Eyeglasses glasses, also known as eyeglasses pipes, are the metal parts that make up the nose pads of eyeglasses. Eyeglasses pipes are used to install and fix the nose pads to support the weight of the frame, playing an important role in the comfort, stability, and aesthetics of the glasses. An eyeglasses pipe consists of two parts: the bowl and the pipe wire. The bowl is used to fix the nose pads, usually a metal cup-shaped or U-shaped clip structure. The pipe wire is a metal rod connecting the frame and the bowl, which can be bent and adjusted to fit the shape of the bridge of the nose. Generally, the bowl and pipe wire are formed separately. The bowl can be stamped, and then holes are drilled and threads tapped on the side of the bowl to secure the nose pad screws. The pipe wire is bent and post-processed. Finally, the bowl and pipe wire are welded together.
[0003] In existing technologies, the welding of pipe bowls and pipe wires typically involves manually placing the pipe bowl and pipe wire into appropriate fixtures for positioning and fixing before welding. Manual welding is inefficient, and the quality varies between workers, resulting in poor quality consistency. Furthermore, the small size of the pipe bowl and pipe wire presents challenges for manual alignment and welding, which is also one of the difficulties in automated welding.
[0004] Therefore, it is necessary to provide a spectacle pipe welding equipment that can automatically feed, position, and align the welding to improve production efficiency and achieve good welding results. Utility Model Content
[0005] The purpose of this invention is to provide a welding equipment for eyeglasses and pipes that can automatically feed materials, automatically position and automatically align and weld, thereby improving production efficiency and achieving good welding results.
[0006] To achieve the above objectives, this utility model provides a welding device for eyeglasses pipes, suitable for welding pipe bowls and pipe wires into a single structure, including a device mounted on a frame:
[0007] The pipe bowl feeding device includes a feeding mechanism, a dispensing mechanism, and a detection mechanism. The feeding mechanism is equipped with a feeding track. The dispensing mechanism includes a dividing plate with multiple receiving slots for holding pipe bowls. Rotating the dividing plate allows the feed end of the feeding track to align with different receiving slots, thus pushing the pipe bowls into different receiving slots. The detection mechanism is located on one side of the dividing plate and is used to detect the state of the pipe bowls in the receiving slots.
[0008] For use in pipe feeding devices;
[0009] The positioning and clamping device includes a first fixture for receiving and positioning a pipe bowl, and a second fixture for receiving and positioning a pipe thread.

[0011] With the above technical solution, the eyeglasses pipe welding equipment of this utility model includes a pipe bowl feeding device, a pipe thread feeding device, a positioning and clamping device, and a welding device, all mounted on a frame. The pipe bowl feeding device includes a feeding mechanism, a separating mechanism, and a detection mechanism. The pipe bowl can be automatically fed out by the feeding mechanism. The separating mechanism separates the pipe bowls for feeding, allowing the detection mechanism to determine the feeding status of the pipe bowls, ensuring that the pipe bowls can properly cooperate with the pipe thread for welding after feeding. The pipe thread feeding device automatically feeds the pipe thread. The positioning and clamping device includes a first fixture and a second fixture. The first fixture receives and positions the pipe bowl, and the second fixture receives and positions the pipe thread. The first and second fixtures are brought close together to assemble the pipe bowl and pipe thread, and then the welding device welds the pipe bowl and pipe thread into a single eyeglasses pipe. This invention relates to a welding equipment for eyeglasses and pipes, which can automatically feed materials and automatically position and align the pipe bowl and pipe thread, resulting in high automation efficiency and good welding effect.

The receiving block is connected to the pipe wire feeding device and enables the pipe wire to be stacked in the receiving block in a preset state. The first power component drives the first fixture to move back and forth to receive the pipe bowl in the feeding track and bring it close to the second fixture. The second power component drives the second fixture to move back and forth to receive the pipe wire in the receiving block and bring it close to the first fixture, so that the pipe wire can cooperate with the pipe bowl.

[0037] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0038] Please see Figure 1This utility model provides a spectacle pipe welding device 100, suitable for welding a pipe bowl 102 and a pipe thread 103 into a single spectacle pipe. The spectacle pipe welding device 100 includes a pipe bowl feeding device 10, a pipe thread feeding device 20, a positioning and clamping device 30, and a welding device 40, all mounted on a frame 101. The pipe bowl feeding device 10 includes a feeding mechanism 11, a distributing mechanism 12, and a detection mechanism 13. The feeding mechanism 11 is provided with a feeding track 113, and the distributing mechanism 12 includes a dividing plate 121. The dividing plate 121 has multiple receiving slots 1211 for accommodating the pipe bowl 102. Rotating the dividing plate 121 allows the feed end of the feeding track 113 to engage with different receiving slots 1211, thus pushing the pipe bowl 102 into different receiving slots 1211. The detection mechanism 13 is located on one side of the indexing plate 121 and is used to detect the state of the pipe bowl 102 in the receiving groove 1211. The detection mechanism 13 determines that the state of the pipe bowl 102 fed into the receiving groove 1211 is suitable for welding with the pipe thread 103. Since the welding position of the pipe bowl 102 and the pipe thread 103 is fixed, it is necessary to use the detection mechanism 13 to determine that the state of the pipe bowl 102 discharged from the pipe thread 103 is suitable for welding with the pipe thread 103. The pipe thread feeding device 20 is used for automatic discharge of the pipe thread 103. The positioning and clamping device 30 is connected to the pipe bowl feeding device 10 and the pipe thread feeding device 20 respectively, so that the pipe bowl 102 and the pipe thread 103 can be pre-positioned and fitted in order to be welded into an integral structure. The positioning and clamping device 30 includes a first fixture 311 for receiving and positioning the pipe bowl 102 and a second fixture 321 for receiving and positioning the pipe thread 103. The first fixture 311 can be connected to the indexing plate 121 and can move close to the second fixture 321, while the second fixture 321 can move close to the first fixture 311. The welding device 40 is used to weld the pipe bowl 102 in the first fixture 311 and the pipe wire 103 in the second fixture 321 into a single eyeglasses pipe.
[0039] With the above technical solution, the eyeglasses pipe welding equipment 100 of this utility model includes a pipe bowl feeding device 10, a pipe thread feeding device 20, a positioning and clamping device 30, and a welding device 40, all mounted on a frame 101. The pipe bowl feeding device 10 includes a feeding mechanism 11, a separating mechanism 12, and a detection mechanism 13. The pipe bowl 102 can be automatically discharged by the feeding mechanism 11. The separating mechanism 12 is used to feed the pipe bowl 102 separately, so that the detection mechanism 13 can determine the discharge status of the pipe bowl 102, ensuring that the pipe bowl 102 can be well aligned with the pipe thread 103 after discharge, allowing for better welding of the pipe bowl 102 and the pipe thread 103. The pipe thread feeding device 20 can automatically discharge the pipe thread 103. The positioning and clamping device 30 includes a first fixture 311 and a second fixture 321. The first fixture 311 is used to receive and position the pipe bowl 102, and the second fixture 321 is used to receive and position the pipe thread 103. The first fixture 311 and the second fixture 321 are brought close together to assemble the pipe bowl 102 and the pipe thread 103. Then, the pipe bowl 102 and the pipe thread 103 are welded into a single eyeglasses pipe by the welding device 40. The eyeglasses pipe welding equipment 100 of this invention can automatically feed materials and automatically position and align the pipe bowl 102 and the pipe thread 103, with high automation efficiency and good welding effect.
[0040] Please see Figure 1 , Figure 4 and Figure 5In some optional embodiments, the dispensing mechanism 12 includes a support frame 120, within which a fixed seat 122 is disposed, and an indexing plate 121 is rotatably disposed within the fixed seat 122. Specifically, a rotational power assembly 123 connected to the indexing plate 121 is disposed on the support frame 120. The rotational power assembly 123 operates to drive the indexing plate 121 to rotate along the fixed seat 122 at a preset speed, and then stops at certain time intervals so that the detection mechanism 13 can perform state detection on the pipe bowl 102 in the receiving groove 1211. On the other hand, the feeding mechanism 11 includes a vibratory plate 111 and a linear vibration assembly 112 connected to the feeding track 113. The feeding track 113 includes a first feeding section 1131 and a second feeding section 1132. The first feeding section 1131 is connected between the vibrating plate 111 and the fixed base 122. The second feeding section 1132 is located on the side of the fixed base 122 away from the vibrating plate 111 and can be connected to the first fixture 311. It can be understood that the indexing plate 121 is provided with a plurality of receiving slots 1211 for accommodating the pipe bowl 102 at certain intervals along its circumference. By rotating the indexing plate 121, each receiving slot 1211 can be connected to either the first feeding section 1131 or the second feeding section. When the receiving slot 1211 is connected to the first feeding section 1131, the pipe bowl 102 in the vibrating plate 111 can be fed into the receiving slot 1211 along the first feeding section 1131. When the receiving trough 1211 connects to the second feeding section 1132, it can convey the pipe bowl 102 that meets the detection requirements to the first fixture 311. Both the first feeding section 1131 and the second feeding section 1132 are connected to the vertical vibration assembly 112. The vertical vibration assembly 112 can better convey the pipe bowl 102 into the indexing plate 121, and can better convey the pipe bowl 102 in the second feeding section 1132 into the first material trough 3111 of the first fixture 311.
[0041] Please see Figure 1 , Figure 4 and Figure 5In some optional embodiments, the fixed base 122 has a discharge channel 1221 that connects to the receiving groove 1211, and the support frame 120 is provided with a first air blowing assembly 14 and a second air blowing assembly 15. The first air blowing assembly 14 is aligned with the discharge channel 1221, and pipe bowls 102 that do not meet the status detection are blown into the discharge channel 1221 for discharge. The second air blowing assembly 15 is aligned with the second feeding section 1132, and pipe bowls 102 that meet the status detection are blown into the second feeding section 1132 for discharge. Specifically, the detection mechanism 13 mainly detects the orientation of the pipe bowls 102 in the receiving groove 1211, and only pipe bowls 102 that can be welded to the pipe thread 103 in the positioning and clamping device 30 are discharged from the second feeding section 1132. If the pipe bowl 102 does not meet the requirements for matching the pipe line 103, the pipe bowl 102 will be blown out through the discharge channel 1221 and then returned to the vibrating plate 111 for vibration discharge.
[0042] Please see Figure 1 , Figure 2 and Figures 6 to 8 In some optional embodiments, the positioning and pressing device 30 includes a first positioning mechanism 31 and a second positioning mechanism 32. The first positioning mechanism 31 includes a first fixture 311 and a first power assembly 312 connected to the first fixture 311. The second positioning mechanism 32 includes a second fixture 321, a second power assembly 324, a receiving block 322, and a pressing assembly 323. The second power assembly 324 is connected to the second fixture 321, and the receiving block 322 and the pressing assembly 323 are both disposed on the second fixture 321. The receiving block 322 is connected to the pipe wire feeding device 20 and enables the pipe wires 103 to be stacked in the receiving block 322 in a preset state. The receiving block 322 has a receiving cavity 3221 for accommodating multiple pipe wires 103. The pipe wire feeding device 20 is provided with a material channel 21 adapted to the receiving cavity 3221, and the material channel 21 is also provided with a material cavity adapted to the receiving cavity 3221. The pipe wire feeding device 20 vibrates to discharge the pipe wire 103, causing it to enter the material chamber in a certain state and then enter the receiving cavity 3221 of the receiving block 322. Specifically, the first power component 312 drives the first fixture 311 to move back and forth to receive the pipe bowl 102 in the feeding track 113 and bring it close to the second fixture 321. The second power component 324 drives the second fixture 321 to move back and forth to receive the pipe wire 103 in the receiving block 322 and bring it close to the first fixture 311, so that the pipe wire 103 can contact and adhere to the pipe bowl 102 for welding.
[0043] Please see Figure 1 , Figure 3 and Figures 6 to 8In some optional embodiments, the second positioning mechanism 32 further includes a pressing component 323, which is vertically positioned above the second fixture 321 to fix the pipe thread 103 in the second feed trough 3211, so that the pipe thread 103 can better cooperate with the pipe bowl 102. Specifically, after the second fixture 321 receives the pipe thread 103 at the receiving block 322, it slides closer to the first fixture 311 under the action of the second power component 324, and then the pressing component 323 moves to position the pipe thread 103 in the second fixture 321. On the other hand, a first feed trough 3111 that cooperates with the pipe bowl 102 is provided in the first fixture 311. The first feed trough 3111 is used to receive and accommodate the pipe bowl 102 at the second feeding section 1132. A second feed trough 3211 that cooperates with the pipe thread 103 is provided in the second fixture 321, and the second feed trough 3211 is used to accommodate the pipe thread 103. The first fixture 311 and the second fixture 321 are brought close together so that the pipe bowl 102 in the first feed trough 3111 and the pipe wire 103 in the second feed trough 3211 come into contact with each other, so that the welding device 40 can weld the pipe bowl 102 and the pipe wire 103 into a single structure.
[0044] Please see Figure 1 , Figure 3 and Figure 9 In some optional embodiments, the welding apparatus 40 includes a feed module 42, a traction module 43, and a coil 41 mounted on a base frame 401. A linkage assembly 44 is provided between the feed module 42 and the traction module 43, and the welding wire 411 on the coil 41 is fed by the feed module 42 and the traction module 43 to weld the pipe bowl 102 and the pipe wire 103. A container 301 for providing flux is provided between the first fixture 311 and the second fixture 321.
[0045] Please see Figure 1 and Figure 9In some optional embodiments, the feeding module 42 includes a base 421, a feeding platform 422, a wire-setting assembly 423, a wire-pressing assembly 424, and a welding assembly 425. The base 421 is mounted on the linkage assembly 44, and the feeding platform 422 is slidably mounted on the base 421. The wire-setting assembly 423 is located at the end of the base 421 away from the coil 41, and the wire-pressing assembly 424 is mounted on the feeding platform 422. One end of the welding assembly 425 is located on the side of the wire-pressing assembly 424 near the coil 41, and the other end of the welding assembly 425 is located on the side of the wire-setting assembly 423 away from the coil 41. The welding assembly 425 is used for the welding wire 411 to pass through and guides the welding wire 411. The welding wire 411 passes through the welding assembly 425 and, driven by the feeding platform 422, moves closer to or away from the container 301. Specifically, the wire pressing assembly 424 presses and positions the welding wire 411 on the feed stage 422, so that the feed stage 422 can move the welding wire 411 closer to the container 301 during its movement, ensuring that the welding wire 411 contacts the flux, achieving flux adhesion before welding. After the welding wire 411 contacts the flux, the feed stage 422 moves the welding wire 411 slightly backward, so that the welding wire 411 is between the first fixture 311 and the second fixture 321, for welding the pipe bowl 102 and the pipe wire 103. At this time, the wire pressing assembly 424 always maintains the wire pressing state. It can be understood that when the pipe bowl 102, the pipe wire 103, and the welding wire 411 all reach the welding position, the pipe bowl 102 and the pipe wire 103 are in close contact, and the welding wire 411, which has been coated with flux, is located directly above the weld point. Welding begins, and simultaneously, the welding wire 411 is pressed down. Upon contact with the conductive surface, the welding wire 411 is instantly heated and melted. Under the action of flux, the melting and flow of the welding wire 411 is accelerated and it wraps around the weld point. Welding stops after a set time, and the welding is complete. In this embodiment, resistance welding is used to weld the pipe bowl 102 and the pipe wire 103. Compared with laser welding and high-frequency welding, the eyeglasses pipe welding equipment 100 of this invention produces better welding results, is more aesthetically pleasing, and has higher welding strength. On the other hand, the feed stage 422 moves the welding wire 411 forward a certain distance each time, allowing the welding wire 411 to contact the flux. Then, the feed stage 422 moves the welding wire 411 backward a small distance, returning it to the space between the first fixture 311 and the second fixture 321. The wire pressing assembly 424 always maintains the wire pressing state. When the feed stage 422 moves close to the wire positioning component 423 multiple times, the wire positioning component 423 presses down on the welding wire 411, while the wire pressing component 424 releases the welding wire 411. The wire pressing component 424 slides back to the starting position with the feed stage 422, while the welding wire 411 remains in its original position. Then, the wire pressing component 424 presses down on the welding wire 411 again, the wire positioning component 423 releases the welding wire 411, and the feed stage 422 slides forward again, driving the wire pressing component 424 to move forward with the welding wire 411, thus realizing the cyclic feeding of the welding wire 411. The structure is simple and reasonable.
[0046] Please see Figure 1 and Figure 9 In some optional embodiments, the linkage component 44 is rotatably mounted on the base frame 401. A rotating shaft 441 is provided at the bottom of the linkage component 44, and an arc-shaped groove 4011 is provided on the base frame 401 to cooperate with the rotating shaft 441. The rotating shaft 441 can drive the feed module 42 and the traction module 43 mounted on the linkage component 44 to rotate within a certain range along the arc-shaped groove 4011. The traction module 43 includes a swing arm 431 connected between the linkage component 44 and the coil 41. A traction cylinder 432 is also mounted on the base frame 401. The output end of the traction cylinder 432 is connected to the swing arm 431. The action of the traction cylinder 432 causes the swing arm 431 to drive the linkage component 44 and the feed module 42 thereon to swing, thereby causing the welding wire 411 to adjust its angle under the action of the welding component 425. The traction cylinder 432 drives the swing arm 431 to swing up and down, which in turn pulls the welding wire 411 to swing up and down, so that the welding wire 411 can reliably contact the welding point and ensure welding quality.
[0047] like Figures 1 to 9As shown, the eyeglasses pipe welding equipment 100 of this utility model includes a pipe bowl feeding device 10, a pipe thread feeding device 20, a positioning and clamping device 30, and a welding device 40, all mounted on a frame 101. The pipe bowl feeding device 10 includes a feeding mechanism 11, a separating mechanism 12, and a detection mechanism 13. The pipe bowl 102 is automatically fed out by the feeding mechanism 11, and the separating mechanism 12 feeds the pipe bowl 102 separately at certain intervals. The detection mechanism 13 determines the feeding status of the pipe bowl 102, ensuring that the pipe bowl 102 can be well aligned with the pipe thread 103 after feeding, allowing for better welding of the pipe bowl 102 and pipe thread 103. The pipe thread feeding device 20 automatically feeds the pipe thread 103. The positioning and clamping device 30 includes a first fixture 311 and a second fixture 321. The first fixture 311 is used to receive and position the pipe bowl 102. The second fixture 321 is used to receive the pipe thread 103 in the receiving block 322 and positions the pipe thread 103 through the pressing component 323. The receiving block 322 is connected to the material channel 21 of the pipe thread feeding device 20, and the pipe thread 103 is stacked in the receiving block 322 in a certain state. In addition, the first fixture 311 and the second fixture 321 are close to each other to combine the pipe bowl 102 and the pipe thread 103. Then, the welding device 40 welds the pipe bowl 102 and the pipe thread 103 into a single eyeglasses pipe. Moreover, the feeding module 42 can effectively drive the welding wire 411 to contact the flux for welding, and can also adjust the angle of the welding wire 411 under the action of the traction module 43, so that the welding wire 411 can better weld the pipe bowl 102 and the pipe thread 103. Furthermore, resistance welding is employed. Upon welding commences, the welding wire 411 is pressed down, and the workpiece heats up instantly upon contact with the conductive surface, melting the welding wire 411. With the aid of flux, the melting and flow of the welding wire 411 is accelerated, enveloping the weld point, resulting in a better, more aesthetically pleasing weld and higher weld strength. This utility model's eyeglasses pipe welding equipment 100 can automatically feed materials and automatically position and align the pipe bowl 102 and pipe wire 103, achieving high automation efficiency and excellent welding results.
