Description

Technical Field

[0001] The invention belongs to the technical field of welding devices, in particular to an automatic welding device for processing metal eyeglass frames. Background Art

[0002] Metal glasses frames, also known as glasses frames, are the frames of glasses made of metal materials. Their main function is to support the lenses. They are suitable for various occasions such as correcting vision, protecting eyes, and matching clothes. During the production and processing of glasses frames, a welding machine is needed to weld the center beam accessories on the glasses frames to the two glasses frames to form a complete glasses frame.

[0003] In a Chinese patent with application number 202222849734.X, a high-frequency automatic welding machine for eyeglass frames is disclosed. The eyeglass frames and middle beams are placed in a mold frame, and then the two ends of the middle beams are automatically welded to the eyeglass frames through a welding head. During the welding process, only the rotating structure is driven to facilitate the placement of accessories and the removal of the welded eyeglass frames. However, generally, when welding is performed by the welding head, only the bottom of the welding head contacts the position between the end of the middle beam and the eyeglass frame for welding. Although the welding operation can be completed quickly in this way, the welding is only performed at the position between the end of the middle beam and the eyeglass frame, while other positions between the middle beam and the eyeglass frame cannot be welded again, which affects the welding effect and welding firmness between the middle beam and the eyeglass frame.

The top and bottom of the rotating plate 200 are both provided with grooves 203 for the plate frame 213 and the mold frame 206 to be embedded.

[0021] Embodiment 2 Based on Example 1, please refer to Figure 1-Figure 4 The main rotating assembly includes a reduction motor 202, a right rotating column is fixedly provided at the working end of the reduction motor 202, the end of the right rotating column extends to one side of the rotating plate 200, a left rotating column is rotatably provided between the other side of the rotating plate 200 and the mold frame 206, a side frame 204 is fixedly provided on one side of the mold frame 206, and the reduction motor 202 is fixed on the top of the side frame 204. The reduction motor 202 can drive the rotating plate 200 and other structures to rotate, so as to facilitate the discharge of welded eyeglass frames and center beam accessories.

[0022] The present invention uses a designed rotating mechanism. During use, the eyeglass frame and the center beam accessory are placed on the electromagnetic suction plate 205 in the mold frame 206 and fixed by the electromagnetic suction plate 205. During the welding process, the mold frame 206 is driven to rotate by the driving motor 210, thereby driving the eyeglass frame and the center beam accessory to synchronously realize a 180-degree rotation, so that welding can be performed at different positions between the eyeglass frame and the center beam accessory, thereby increasing the welding effect and welding firmness between the center beam accessory and the eyeglass frame. The rotating plate 200 and the mold frame 206 can also be rotated and flipped, so that the welded eyeglass frame and the center beam accessory can be easily discharged.

[0023] During use, the eyeglass frame and the middle beam accessories to be welded are placed in the mold frame 206 and contacted with the surface of the electromagnetic suction plate 205, and then the electromagnetic suction plate 205 is turned on. At this time, the eyeglass frame and the middle beam accessories on the surface of the electromagnetic suction plate 205 are adsorbed and fixed, which can avoid the displacement of the eyeglass frame and the middle beam accessories during the welding process, resulting in crooked welding. Then, when welding begins, the welding head 101 moves to the position between the eyeglass frame and the middle beam accessories for welding operation. Before welding, the electric slide rail 212 is turned on, and the slider 211 on the electric slide rail 212 moves to the left and drives the driving motor 210 below to move, thereby driving the rotating wheel 209 to move, and then the rotating wheel 209 contacts the rotating wheel 215, and then the driving motor 210 is started. The working end of the driving motor 210 rotates to drive the rotating wheel 209 to rotate 90 degrees forward, thereby driving the rotating rod 216 and the mold frame 206, the electric The magnetic plate 205 and the plate frame 213 are then rotated 90 degrees to a vertical position, at which time the welding head 101 can be moved to make the end contact with the welding position, and then the welding head 101 is turned on for welding, and at the same time the driving motor 210 makes the working end reverse 180 degrees to synchronously realize the 180-degree rotation of the eyeglass frame and the middle beam accessory, so that welding can be realized while rotating, and 180-degree multi-position welding between the eyeglass frame and the middle beam accessory is realized. At this time, more molten solder is produced after welding at multiple positions, which covers the unwelded positions on the back of the eyeglass frame and the middle beam accessory, thereby welding the back side as well, thereby increasing the welding firmness between the eyeglass frame and the middle beam accessory. After reversing 180 degrees, the welding is completed and the welding is stopped. At this time, the driving motor 210 drives the mold frame 206 and other structures to rotate 90 degrees in the forward direction to restore to the original position to complete the welding operation; Then, the reduction motor 202 is turned on, driving the rotating plate 200 and the mold frame 206 and other structures to rotate 180 degrees and flip. At this time, the mold frame 206 equipped with the welded glasses frame and the middle beam accessories faces downward, and then the electromagnetic suction plate 205 is closed. At this time, the welded glasses frame and the middle beam accessories adsorbed and fixed on the electromagnetic suction plate 205 fall into the collection box 107 below to complete the discharge. During the period when the rotating plate 200 and the mold frame 206 and other structures rotate 180 degrees and flip, the electric push rod 207 is started, and the working end of the electric push rod 207 moves downward and retracts into the inside of the electric push rod 207, driving the mold frame 206, the electromagnetic suction plate 205 and other structures to rotate 180 degrees. The rotating plate 200 moves downward, and then the plate frame 213 and the mold frame 206 are embedded in the corresponding groove 203, and the other group of mold frames 206, the electromagnetic suction plate 205 and the plate frame 213 and other structures below the rotating plate 200 will move upward under the action of the electric push rod 207 and disengage from the corresponding groove 203. After rotating 180 degrees, the other group of mold frames 206, the electromagnetic suction plate 205 and the plate frame 213 and other structures below the rotating plate 200 are located above the rotating plate 200. Then the other eyeglass frames and center beam accessories to be welded can be put into the mold frame 206 and the electromagnetic suction plate 205 and placed, and the welding operation is performed reciprocatingly.

[0024] Embodiment 3 Based on Example 2, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 7 , Fig. 9 , Fig.10 and Fig.11 An auxiliary ejector is provided between the rotating plate 200 and the top frame 106, and the auxiliary ejector includes an inclined plate 300 fixed to the inner wall of the top frame 106, a moving column 303 slidably arranged inside the rotating plate 200, and two sets of lifting columns 301. When the two sets of lifting columns 301 move in opposite directions, the welded eyeglass frames and middle beam accessories can be ejected outward for discharging. A vertical long hole is opened inside the rotating plate 200, and the lifting column 301 is located inside the vertical long hole; The rotating plate 200 is provided with a plurality of vertical slots 304 and a socket 308. A moving column 303 is provided inside the socket 308. The moving column 303 can reciprocate inside the socket 308. A mounting spring 307 and a mounting ring 302 are sleeved on the outside of one end of the moving column 303. The two ends of the mounting spring 307 are fixed on the rotating plate 200 and the mounting ring 302 respectively. One end of the movable column 303 can contact the end of the inclined plate 300, and two sets of fixed plates 305 are fixedly arranged on the outside of the lifting column 301. A connecting spring 306 is fixedly arranged between the fixed plate 305 and the inner wall of the vertical groove 304. Through the connecting spring 306, when the lifting column 301 is extended outward, it can be easily reset later to allow the lifting column 301 to move to the inside of the rotating plate 200.

[0025] The auxiliary ejector designed in the present invention can eject outward a portion of the eyeglass frames and center beam accessories stuck on the mold frame 206 during the unloading process after welding is completed. During the ejection, one end of the moving column 303 contacts the inclined plate 300, and the moving column 303 moves toward the back side of the rotating plate 200 to eject the lifting column 301 outward, and then the eyeglass frames and center beam accessories stuck in the mold frame 206 and the electromagnetic suction plate 205 are ejected outward by the lifting column 301 to realize unloading, so as to facilitate the unloading of the eyeglass frames and center beam accessories that have been welded, avoid the situation where some eyeglass frames and center beam accessories are stuck in the mold frame 206 and the electromagnetic suction plate 205 and affect the unloading, and facilitate use.

[0026] When the welding is completed, the rotating plate 200, the mold frame 206 and other structures will rotate and flip, which will drive the moving column 303 inside the rotating plate 200 to rotate and flip. During the rotation and flipping, the outer end of the moving column 303 will hit the end of the inclined plate 300, and then the moving column 303 and the inclined plate 300 will be flush. During this period, since the outer end of the moving column 303 is a spherical structure and the end of the inclined plate 300 is a sloped structure, after the outer end of the moving column 303 hits the end of the inclined plate 300, the moving column 303 will move toward the back side of the rotating plate 200, driving the mounting ring 302 to move, and then the mounting spring 307 begins to compress due to the movement and extrusion of the mounting ring 302. When the moving column 303 moves, the other end hits the two sets of lifting columns 301. The other end of the moving column 303 is a sloped structure, which will cause the two groups of lifting columns 301 to move in opposite directions, driving the fixed plate 305 to move. At this time, the connecting spring 306 begins to stretch under the influence of the fixed plate 305, and then the outer end of the lifting column 301 extends outward into the mold frame 206 and the electromagnetic suction plate 205, pushing some stuck eyeglass frames and center beam accessories in the mold frame 206 and the electromagnetic suction plate 205 downward for discharge. When the discharge is completed, the rotating plate 200, the mold frame 206, etc. continue to rotate, driving the moving column 303 to move, and then the outer end of the moving column 303 is separated from the end of the inclined plate 300. At this time, according to the above-mentioned opposite principle, the moving column 303 moves back to its original position, and the two groups of lifting columns 301 move to enter the interior of the rotating plate 200.

[0027] Embodiment 4 Based on Example 3, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7 A cleaning part for cleaning the inner wall of the mold frame 206 is provided on the rotating plate 200, and the cleaning part includes an air pump 401 fixed on the top of the rotating plate 200. The air pump 401 generates high-pressure gas, which is then blown outward through the inclined nozzle 402. The electric valve 403 located below the vertical pipe 400 can also be opened in advance, so that the welding position between the welded eyeglass frames and the center beam accessories can be cooled, and the dust and foreign matter attached to the inside can be blown off after the material is discharged. The vertical pipe 400 is fixedly provided inside the rotating plate 200, and two groups of electric valves 403 are provided outside the vertical pipe 400. Two groups of inclined nozzles 402 are fixedly provided outside both ends of the vertical pipe 400, and a connecting pipe is fixedly provided between the air pump 401 and the vertical pipe 400.

[0028] The cleaning piece designed in the present invention can spray gas toward the inner wall surface of the mold frame 206 and the electromagnetic suction plate 205 through the inclined nozzle 402 after the welded glasses frame and the center beam accessories are discharged to blow off some dust and foreign matter attached to the inner wall surface, thereby avoiding the situation in which some dust and foreign matter affect the welding quality during the subsequent welding process, thereby improving the welding quality between the glasses frame and the center beam accessories.

[0029] When the welded eyeglass frames and center beam accessories are flipped to the downward direction and discharged under the rotation of the rotating plate 200, the electric valve 403 at the bottom of the vertical pipe 400 is opened, and then the inclined nozzle 402 sprays gas to the inner wall of the mold frame 206 and the surface of the electromagnetic suction plate 205 to blow off the dust and foreign matter attached to the inner wall of the mold frame 206 and the surface of the electromagnetic suction plate 205, so that the inner wall of the mold frame 206 and the surface of the electromagnetic suction plate 205 remain clean, avoiding the situation where some dust and foreign matter affect the welding quality during the subsequent welding process.

[0030] In this embodiment, a base frame 100 is fixedly provided at the bottom of the top frame 106, a collection box 107 is provided on the base frame 107, two sets of Y-axis frames 105 are fixedly provided on the top of the top frame 106, an X-axis frame 104 is slidably provided on the Y-axis frame 105, a lifting cylinder 103 is slidably provided on the X-axis frame 104, a sliding rail 102 is provided on the lifting cylinder 103, a welding head 101 is fixed on the sliding rail 102, the lifting cylinder 103 can drive the sliding rail 102 and the welding head 101 to move up and down, the lifting cylinder 103 can move left and right on the X-axis frame 104, and the X-axis frame 104 can move forward and backward on the Y-axis frame 105, so as to facilitate the movement of the welding head 101 for automatic welding operation.

[0031] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
