[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example

[0028] Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a heating wire bonding device for automotive rearview mirror lenses. The heating wire bonding device for automotive rearview mirror lenses includes a conveyor line 11, with a conveyor belt in the middle and fixed frames for mounting the conveyor belt on both sides.

[0029] It also includes a bonding component 2, which is set on the top of the conveyor line 11. The bonding component 21 includes a pressing component 21, which includes a support frame 211 fixed to the top of the conveyor line 11. The support frame 211 is L-shaped and has a movable block 212 inside. The movable block 212 can move within the support frame 211. A cylinder 213 is fixed inside the movable block 212. A positioning frame 214 is fixed at the output end of the cylinder 213. The shape of the positioning frame 214 is the same as that of the rearview mirror lens. A suction cup 215 is fixed on the positioning frame 214 and is located at both ends of the positioning frame 214. A pressure roller 216 is set on the top of the conveyor line 11 and a stabilizing block is fixed on the top of the fixed frame. The pressure roller 216 is rotatably connected to the stabilizing block through a rotating shaft. When the heating element and the lens are bonded, the conveyor line 11 drives the lens to move to the bottom of the pressure roller 216. The pressure roller 216 rolls the two together, thereby making the heating element and the lens bond more tightly.

[0030] The bonding component 2 also includes a storage component 22, which includes a first storage frame 221 fixed to the top of the conveyor line 11. The first storage frame 221 is used to store lenses, and an opening is provided on one side of the bottom of the first storage frame 221. The bottom lens is in contact with the conveyor belt. When the conveyor belt moves, it will drive the bottom lens to move outward from the opening, while the upper lens will be blocked by the first storage frame 221 and will not move. Therefore, only one lens will move at a time.

[0031] A second storage frame 222 is fixed on one side of the conveyor line 11. The second storage frame 222 is used to store the heating element. A feeding plate 223 is provided inside the second storage frame 222. The feeding plate 223 is used to support the heating element and can drive the heating element to move upward.

[0032] When the conveyor belt moves the lens, the movable block 212 drives the cylinder 213 and the positioning frame 214 to move to the top of the second storage box 222, and the uppermost heating element is attracted by the suction cup 215. Then, the movable block 212 drives the cylinder 213 and the positioning frame 214 to move above the conveyor belt. When the lens moves to the bottom of the positioning frame 214, the conveyor belt stops moving. At this time, the cylinder 213 drives the positioning frame 214 to move downward, so that the positioning frame 214 wraps the lens inside. At the same time, the heating element will adhere to the lens, thus completing the adhesion between the heating element and the lens. During the adhesion process, the positioning frame 214 constrains and positions the lens, so that it can be accurately adhered to the heating element, thereby avoiding misalignment, wrinkles, etc., and enhancing product consistency and adhesion firmness, eliminating bubbles and curling edges, and improving heat conduction efficiency. Example

[0033] Reference Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, the bonding component 2 also includes a film peeling component 23, which includes a support frame 231 fixed to one side of the conveyor line 11, a support rod 232 inserted into the support frame 231, a fixing roller 233 fixed to the top of the support rod 232, the top of the fixing roller 233 being coated with adhesive, and a first spring 234 fixed to the bottom of the support rod 232.

[0035] When the positioning frame 214 causes the heating element to separate from the second storage frame 222, the fixing roller 233 will move upward and adhere to the bottom of the heating element. At this time, the protective paper on the bottom of the heating element will be stuck by the adhesive on the top of the fixing roller 233. As the positioning frame 214 moves, the protective paper can be completely peeled off, thus exposing the adhesive side of the bottom of the heating element, which can then adhere to the lens when it is bonded to the lens.

[0036] The first spring 234 is used to apply a downward pulling force to the support rod 232, causing it to drive the fixed roller 233 to move downward and reset.

[0037] Specifically, a rotating rod 235 is rotatably connected to one side of the fixed roller 233 via a rotating shaft. The rotating rod 235 is used to position the storage frame 236, allowing the storage frame 236 to rotate around the axis of the fixed roller 233. The storage frame 236 is fixed to one side of the end of the rotating rod 235. The storage frame 236 is used to store the adhesive. A glue roller 237 is rotatably connected inside the storage frame 236. When the glue roller 237 moves on top of the fixed roller 233, it can apply the adhesive to the top of the fixed roller 233.

[0038] A scraper 238 is fixed to one side of the storage box 236. The scraper 238 is in contact with the top of the fixed roller 233, and the surface of the scraper 238 is coated with an oily coating to prevent adhesive residue from remaining on the surface of the scraper 238. A rotating rail 239 is fixed to one side of the rotating rod 235. A positioning shaft 230 slides inside the rotating rail 239. The positioning shaft 230 is fixed to the top of the conveyor line 11 by a mounting rod.

[0039] When the fixed roller 233 moves upward, the positioning shaft 230 slides within the rotating rail 239, causing the rotating rail 239 to rotate downward. At this time, the rotating rail 239 drives the rotating rod 235 and the storage frame 236 to rotate downward, causing the storage frame 236 to separate from the top of the fixed roller 233, thereby allowing the top of the fixed roller 233 to contact the bottom of the heating element.

[0040] When the fixed roller 233 moves downward, the positioning shaft 230 and the rotating rail 239 work together to drive the rotating rod 235 and the storage box 236 to rotate upward. At this time, the scraper 238 will remove the adhesive and the attached protective paper from the top of the fixed roller 233, and the protective paper will fall downward and separate from the top of the fixed roller 233. At the same time, the adhesive roller 237 will apply the adhesive to the top of the fixed roller 233 again to ensure that the top of the fixed roller 233 has sufficient adhesion.

[0041] Specifically, the bonding component 2 also includes a lifting component 24, which includes a guide shaft 241 fixed to one side of the support rod 232. One end of the guide shaft 241 is provided with a turntable 242, and a guide groove 242-1 is provided on the turntable 242. The guide shaft 241 is movably connected to the guide groove 242-1, and the guide groove 242-1 is arc-shaped.

[0042] A rotating column 243 is fixed on one side of the turntable 242. A positioning rod 244 is rotatably connected to the outside of the rotating column 243 through a bearing. One side of the positioning rod 244 is fixed to the conveyor line 11.

[0043] When the rotating column 243 rotates, it will drive the turntable 242 to rotate. At this time, the guide shaft 241 will move upward along the guide groove 242-1 and drive the support rod 232 to move upward, which in turn allows the support rod 232 to drive the fixed roller 233 to move upward.

[0044] Specifically, a force-bearing rod 245 is rotatably connected to the outer side of the end of the rotating column 243 via a bearing. A pressing plate 246 is fixed to one side of the positioning frame 214. A torsion spring 247 is fixed to one side of the force-bearing rod 245. The other end of the torsion spring 247 is fixed to the rotating column 243. A force-bearing block 248 is fixed to the outer side of the rotating column 243. A pressing shaft 249 is fixed to one side of the force-bearing rod 245.

[0045] When the positioning frame 214 moves to the top of the second storage frame 222, it will push the force rod 245 to rotate through the extrusion plate 246. At this time, the force rod 245 will not drive the rotating column 243 to rotate. After the positioning frame 214 moves to the top of the second storage frame 222, the extrusion plate 246 will separate from the force rod 245, and the force rod 245 will return to the vertical state under the elastic force of the torsion spring 247.

[0046] When the positioning frame 214 moves toward the top of the conveyor belt, the extrusion plate 246 pushes the force rod 245 to rotate. The force rod 245 drives the extrusion shaft 249 to push the force block 248 to rotate, and through the force block 248 drives the rotating column 243 to rotate, which in turn drives the turntable 242 to rotate. Example

[0047] Reference Figure 2 , Figure 8 and Figure 9 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0048] Specifically, the bonding component 2 also includes a rotating component 25, which includes a fixed post 251 fixed to the bottom of the feeding plate 223, a rotating sleeve 252 rotatably connected to the bottom of the second storage frame 222, a fixed shaft 253 inserted into the rotating sleeve 252, a spiral groove 251-1 opened on the fixed post 251, and the fixed shaft 253 sliding in the spiral groove 251-1.

[0049] When the rotating sleeve 252 rotates, it will drive the fixed shaft 253 to slide in the spiral groove 251-1. Through the cooperation of the two, the fixed column 251 and the feeding plate 223 will move upward, which will in turn cause the feeding plate 223 to drive the heating element to move upward.

[0050] The fixed shaft 253 is tightly connected to the rotating sleeve 252 and can be pulled outward. When the feeding plate 223 moves to the top and the heating plate at the top is no longer there, the fixed shaft 253 can be pulled outward and separated from the spiral groove 251-1. At this time, the feeding plate 223 will move downward and reset under its own weight.

[0051] Specifically, the bonding component 2 also includes a transmission component 26, which includes a movable sleeve 261 rotatably connected to the outside of the rotating sleeve 252 via a bearing. A slide rail 262 is fixed on one side of the movable sleeve 261, and a movable shaft 263 slides inside the slide rail 262. A moving rod 264 is fixed on the outside of the movable shaft 263. The moving rod 264 is L-shaped and its top extends above the second storage frame 222.

[0052] When the positioning frame 214 moves to the top of the second storage frame 222, it will push the moving rod 264 to move. The moving rod 264 drives the movable sleeve 261 to rotate through the cooperation of the movable shaft 263 and the slide rail 262, and drives the rotating sleeve 252 to rotate through the movable sleeve 261.

[0053] Specifically, a locking block 265 is inserted into the movable sleeve 261, with one side of the locking block 265 inclined. A slot 252-1 is provided on the rotating sleeve 252, and the locking block 265 engages with the slot 252-1. The two work together to connect the movable sleeve 261 and the rotating sleeve 252, so that the movable sleeve 261 can only drive the rotating sleeve 252 to rotate in one direction. A positioning sleeve 266 is fixed to one side of the movable sleeve 261, and a second spring 267 is fixed to the inner wall of the positioning sleeve 266. The second spring 267 is used to apply a pushing force to the locking block 265, so that the locking block 265 engages with the slot 252-1 more securely.

[0054] Specifically, a stabilizing column 268 is fixed on one side of the second storage frame 222. There are multiple stabilizing columns 268, which are evenly distributed in a straight line on one side of the second storage frame 222. The stabilizing column 268 is movably connected to the moving rod 264 and is used to position the moving rod 264 to prevent it from shifting during movement.

[0055] A mounting block 269 is fixed to one end of the stabilizing column 268, and a third spring 260 is fixed to one side of the mounting block 269. When the positioning frame 214 separates from the moving rod 264, the third spring 260 will apply a pushing force to the moving rod 264 to reset it.

[0056] Specifically, the bonding component 2 also includes a movable component 27, which includes a connecting block 271 fixed to one side of the movable block 212. A slide groove is provided on one side of the support frame 211. The connecting block 271 is movably connected to the slide groove. A lead screw 272 is threadedly connected to the connecting block 271. A motor 273 is provided at the end of the lead screw 272. A support block is fixed on one side of the support frame 211. The lead screw 272 is rotatably connected to the support block through a bearing.

[0057] Motor 273 drives lead screw 272 to rotate, lead screw 272 drives connecting block 271 to move, which in turn allows connecting block 271 to drive movable block 212 to move.

[0058] When in use, the conveyor belt moves the lens, and the movable block 212 moves through the lead screw 272. The movable block 212 moves the cylinder 213 and the positioning frame 214 to the top of the second storage frame 222, and the uppermost heating element is attracted by the suction cup 215. Then, the movable block 212 moves the cylinder 213 and the positioning frame 214 to the top of the conveyor belt.

[0059] When the positioning frame 214 moves toward the top of the conveyor belt, the extrusion plate 246 pushes the force rod 245 to rotate. The force rod 245 drives the extrusion shaft 249 to push the force block 248 to rotate, and through the force block 248 drives the rotating column 243 to rotate, so that the rotating column 243 drives the turntable 242 to rotate. At this time, the guide shaft 241 moves upward along the guide groove 242-1, and drives the support rod 232 to move upward, which in turn allows the support rod 232 to drive the fixed roller 233 to move upward.

[0060] When the fixed roller 233 moves upward, the positioning shaft 230 slides within the rotating rail 239, causing the rotating rail 239 to rotate downward. At this time, the rotating rail 239 drives the rotating rod 235 and the storage frame 236 to rotate downward, causing the storage frame 236 to separate from the top of the fixed roller 233. This allows the top of the fixed roller 233 to contact the bottom of the heating element. When the positioning frame 214 causes the heating element to separate from the second storage frame 222, the fixed roller 233 moves upward and adheres to the bottom of the heating element. At this time, the protective paper on the bottom of the heating element is adhered by the adhesive on the top of the fixed roller 233. As the positioning frame 214 moves, the protective paper can be completely peeled off, exposing the adhesive side of the bottom of the heating element. When it is attached to the lens, it can adhere to the lens.

[0061] When the lens moves to the bottom of the positioning frame 214, the conveyor belt stops moving. At this time, the positioning frame 214 is driven to move downward by the cylinder 213, so that the positioning frame 214 wraps the lens inside. At the same time, the heating element will adhere to the lens, thus completing the adhesion between the heating element and the lens. During the adhesion process, the positioning frame 214 constrains and positions the lens, so that it can be accurately adhered to the heating element, thereby avoiding misalignment, wrinkles, etc., and enhancing product consistency and adhesion firmness, eliminating bubbles and curling edges, and improving heat conduction efficiency.

[0062] At this time, the first spring 234 will apply a downward pulling force to the support rod 232, causing it to drive the fixed roller 233 to move downward and reset. When the fixed roller 233 moves downward, the positioning shaft 230 and the rotating rail 239 will drive the rotating rod 235 and the storage box 236 to rotate upward. At this time, the scraper 238 will remove the adhesive and the adhesive protective paper on the top of the fixed roller 233 together, and cause the protective paper to fall downward and separate from the top of the fixed roller 233. At the same time, the glue roller 237 will apply the adhesive to the top of the fixed roller 233 again and ensure that the top of the fixed roller 233 has sufficient adhesion.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
