Description

Technical Field

[0001] This invention relates to the field of rubber ring assembly technology, and specifically to a device for assembling rubber rings. Background Technology

[0002] Rubber rings are elastic sealing elements with a circular cross-section. Due to their simple structure, reliable self-sealing performance, and small installation space requirements, they are widely used in machinery, electronic equipment, and automotive parts. They play a crucial sealing role whether stationary or in motion. With the increasing demands for production efficiency and product quality in modern industry, the assembly process of rubber rings is gradually shifting from traditional manual operation to automation and intelligence. Automatic rubber ring assembly equipment has become a research hotspot in the field of non-standard automation equipment.

[0003] Currently, common rubber ring assembly equipment on the market includes, for example, a rubber ring assembly device disclosed in Chinese utility model patent application CN218592877U. This device comprises: a base, an assembly plate rotatably connected to the top of the base via a rotating mechanism, multiple adjustment mechanisms fixedly connected to the top of the assembly plate, each adjustment mechanism containing cylindrical parts, a material preparation column for placing rubber rings fixedly connected to one corner of the top of the base, and a tool box slidably connected to one side of the front of the base. The rotating mechanism improves the efficiency of rubber ring assembly. A servo motor drives a first bevel gear to rotate, which in turn drives a second bevel gear to rotate, which in turn drives a rotating shaft to rotate. The top of the rotating shaft is supported by an assembly plate, causing the assembly plate to rotate. Consequently, multiple assembly cylinders mounted on the top of the assembly plate rotate accordingly. Each assembly cylinder contains cylindrical parts. Workers remove rubber rings via the material preparation column and place them onto the cylindrical parts to complete the assembly process.

[0004] However, existing rubber ring assembly equipment uses a cylindrical part placed inside the adjustment mechanism on the assembly plate to facilitate the operator's placement of the rubber ring. However, it still relies on manual assembly, resulting in low efficiency, high labor intensity, missed parts, and incomplete assembly. Furthermore, it is essentially a simple fixture with limited automation, leading to limitations in precision control, inconvenient debugging and maintenance, and gaps in the adjustment mechanism, posing a risk of injury to the operator's fingers. Additionally, it is only suitable for cylindrical products and cannot be used for plate-shaped products with through holes, meaning it cannot assemble the rubber ring through the product into the through hole.

[0005] In view of the above, the inventors propose the following technical solution. Summary of the Invention

[0030] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0031] See Figures 1 to 10As shown, a device for assembling rubber rings includes: a rubber ring assembly device 23 for assembling rubber rings onto a product 100. The rubber ring assembly device 23 includes a rubber ring assembly clamp 235, an opening / closing module 231 for driving the rubber ring assembly clamp 235 to open or close, and a rubber ring lifting drive module 232 for driving the opening / closing module 231 to rise and fall. The rubber ring assembly clamp 235 includes at least a first clamping arm 237 and a second clamping arm 238 that can open or close relative to each other. The first clamping arm 237 has a first contoured groove 2371 adapted to the rubber ring, and the second clamping arm 238 has a second contoured groove 2381 adapted to the rubber ring. During assembly, the rubber ring lifting drive module 232 drives the first clamping arm 237 and the second clamping arm 238, which are closed relative to each other, upward through the mounting hole 1 of the product 100. 01. Then, the opening and closing module 231 drives the upper ends of the first clamping arm 237 and the second clamping arm 238 to open up to each other. The first contouring groove 2371 and the second contouring groove 2381 are respectively fitted around the first convex ring portion 71 of the rubber ring. The opening and closing module 231 drives the upper ends of the first clamping arm 237 and the second clamping arm 238 to close up to clamp and deform the first convex ring portion 71 of the rubber ring. Then, the rubber ring lifting drive module 232 drives the first clamping arm 237 and the second clamping arm 238 clamping the first convex ring portion 71 to pass downward through the mounting hole 101 of the product 100, so that the second convex ring portion 72 of the rubber ring abuts against the upper edge of the mounting hole 101. Finally, the opening and closing module 231 drives the upper ends of the first clamping arm 237 and the second clamping arm 238 to open up to each other, so that the first convex ring portion 71 of the rubber ring returns to its original position and extends outward to be held in place at the lower edge of the mounting hole 101. In addition, combined with Figure 6 and Figure 10 As shown, a groove 70 is formed between the first convex ring portion 71 and the second convex ring portion 72 of the rubber ring. When the first clamping arm 237 and the second clamping arm 238 are closed together, the edges of the first clamping arm 237 and the second clamping arm 238 are precisely engaged in the groove 70, which can effectively clamp the rubber ring. Preferably, the rubber ring lifting drive module 232 can be a cylinder, an electric cylinder, an electric push rod, or a linear motor.

[0032] This invention completely changes the traditional method of manually assembling rubber rings. A rubber ring assembly mechanism 2 installed on the machine 1 replaces manual assembly, reducing the need for manpower and significantly lowering labor costs. Furthermore, the rubber ring lifting drive module 232 and the opening / closing module 231 drive the rubber ring assembly clamp 235 to lift, pass through the product 100, clamp the rubber ring, and pull it down for assembly. This is more stable and efficient than manual assembly, eliminating problems such as missed parts and incomplete assembly. It is also applicable to assembling rubber rings of different sizes and diameters. In addition, compared with existing structures, this invention uses a mechanical clamp instead of manual hands, effectively avoiding the risk of finger injuries. Moreover, the first clamping arm 237 and the second clamping arm 238 of the rubber ring assembly clamp 235 can open after closing and passing through the product 100 to clamp the rubber ring and deform it, facilitating its pull-down assembly into the mounting hole 101 of the product 100. Even for plate-shaped products with mounting holes 101, it can effectively pass the rubber ring through the product 100 for assembly, with efficient and stable assembly.

[0033] The first clamping arm 237 has a first through hole 2373 at its lower end, and the second clamping arm 238 has a second through hole 2383 at its lower end. The first clamping arm 237 and the second clamping arm 238 are hinged together by a third pivot shaft 2300 passing through the first through hole 2373 and the second through hole 2383, so that the first clamping arm 237 and the second clamping arm 238 form a Y-shape when opened, and the lower dimensions of the first clamping arm 237 and the second clamping arm 238 when opened are smaller than the dimensions of the mounting hole 101. Figure 6 As shown, preferably, the first clamping arm 237 and the second clamping arm 238 are both semi-cylindrical. When closed, they form a cylindrical shape to pass through the mounting hole 101. The lower dimensions of the first clamping arm 237 and the second clamping arm 238 are smaller than the dimensions of the mounting hole 101 to ensure that the first clamping arm 237 and the second clamping arm 238 can still be opened normally after passing through the mounting hole 101.

[0034] The opening and closing module 231 includes an assembly clamp base 236 disposed on the rubber ring lifting drive module 232, a first spring 239 disposed on the assembly clamp base 236 for pushing the first clamp arm 237 to open outward, a second spring 230 disposed on the assembly clamp base 236 for pushing the second clamp arm 238 to open outward, and a closing cylinder 234 disposed on the rubber ring lifting drive module 232. The output end of the closing cylinder 234 is provided with a first closing clamp block 2341 and a second closing clamp block 2342 for driving the first clamp arm 237 and the second clamp arm 238 to close. The first clamp arm 237 and the second clamp arm 238 are also provided with a first clearance part 2372 and a second clearance part 2382, respectively. It is worth mentioning that, after testing, it was found that, since the rubber ring is circular, if the rigid first clamping arm 237 and second clamping arm 238 are not provided with a relief part, the deformation space of the rubber ring will be reduced when clamping the rubber ring, making it difficult to drive the rubber ring through the product 100, affecting the assembly effect, and in severe cases, even damaging the rubber ring. Therefore, by providing the inclined first relief part 2372 and second relief part 2382, the rubber ring is prevented from being crushed, so as to facilitate the clamping of the rubber ring.

[0035] The invention also includes a machine platform 1, on which a rotating disk 11 is rotatably mounted. The rotating disk 11 has a plurality of carriers for positioning the product 100 distributed at intervals along the circumferential direction; and at least one rubber ring assembly mechanism 2, which includes a rubber ring feeding device 21 mounted on the machine platform 1, a rubber ring feeding device 22 mounted on the machine platform 1 for transferring the rubber ring to the carrier, and a rubber ring assembly device 23 mounted below the rotating disk 11 for assembling the rubber ring onto the product; the rubber ring feeding device 21 includes a rubber ring feeding base 211 mounted on the machine platform 1, a rubber ring vibrating disk 212 mounted on the rubber ring feeding base 211, a rubber ring feeding channel 213 mounted on the rubber ring feeding base 211 and connected to the rubber ring vibrating disk 212, and a rubber ring positioning device 214 mounted at the outlet end of the rubber ring feeding channel 213 for adjusting the angle of the rubber ring. Here, the rubber ring vibrates outward from the rubber ring vibrating plate 212 and moves through the feeding channel 213 to the rubber ring positioning device 214, and the angle is adjusted by the rubber ring positioning device 214 so that the rubber ring feeding device 22 can clamp it.

[0036] Specifically, the rubber ring positioning device 214 includes an adjusting base 215, an adjusting stand 216 disposed on the adjusting base 215 and abutting the outlet end of the rubber ring feeding channel 213, an adjusting lifting cylinder 217 disposed on the adjusting base 215, an adjusting lifting column 218 connected to the output end of the adjusting lifting cylinder 217 and passing through the upper end of the adjusting stand 216, and a rubber ring positioning detection element 219 disposed on the adjusting stand 216 for detecting whether the rubber ring is in position. The upper end face of the adjusting stand 216 is provided with a rubber ring positioning groove 2161 for positioning the rubber ring, and the upper end face of the adjusting stand 216 is also provided with a detection groove 2162 communicating with the rubber ring positioning groove 2161 and used for detection by the rubber ring positioning detection element 219. The adjusting stand 216 is provided with a lifting through hole 2163 communicating with the rubber ring positioning groove 2161 and used for the adjusting lifting column 218 to pass through. Here, when the rubber ring moves to the rubber ring positioning groove 2161, the rubber ring positioning detection component 219 detects the rubber ring through the detection groove 2162, and the adjusting lifting cylinder 217 drives the adjusting lifting column 218 to rise, and lifts the rubber ring to rise, so that the rubber ring feeding device 22 can clamp it.

[0037] The rubber ring feeding device 22 includes a rubber ring feeding bracket 221 mounted on the machine base 1, a rubber ring X-axis linear module 222 mounted on the rubber ring feeding bracket 221, a rubber ring Z-axis linear module 223 mounted on the rubber ring X-axis linear module 222 and driven by the rubber ring X-axis linear module 222 to move back and forth, and a rubber ring manipulator 224 mounted on the rubber ring Z-axis linear module 223 and driven by the rubber ring Z-axis linear module 223 to move up and down. Here, the rubber ring manipulator 224 achieves dual-axis movement adjustment through the rubber ring X-axis linear module 222 and the rubber ring Z-axis linear module 223, and can move back and forth between the rotating disk 11 and the rubber ring positioning device 214 to clamp the rubber ring and move it above the carrier for the rubber ring assembly clamp 235 to clamp and assemble.

[0038] Combination Figure 7 As shown, this invention also includes a film laminating mechanism 3, which comprises a film feeding mechanism 31 mounted on the machine base 1 for conveying film, a multi-axis film laminating device 32 mounted on the machine base 1 for laminating film onto the surface of product 100, and a vision positioning device 33 mounted on the machine base 1 for visually positioning film. Here, the film flows outward through the film feeding mechanism 31 and is clamped by the multi-axis film laminating device 32 to be attached to the surface of product 100. When the multi-axis film laminating device 32 moves the film above the vision positioning device 33, the vision positioning device 33 takes a photograph to position the film, ensuring that the film is not skewed or bent, thus ensuring the quality of the lamination.

[0039] Combination Figure 8 As shown, preferably, the film feeding mechanism 31 includes a roll feeding frame 311 mounted on the machine base 1, a feeding shaft 312 rotatably mounted on the roll feeding frame 311, a material belt 313 wound around the feeding shaft 312 and carrying film, a plurality of limiting rods 314 inserted on the roll feeding frame 311 for limiting the material belt 313, a receiving shaft 315 mounted on the roll feeding frame 311 for retrieving the material belt 313, a peeling knife 316 mounted on the roll feeding frame 311 for peeling film off the surface of the material belt 313, and a placement platform 317 mounted beside the peeling knife 316 for placing film for gripping by the suction cup 325. Here, the material belt 313 with film is stored on the feeding shaft 312 and driven by the feeding shaft 312 to move towards the peeling knife 316, so that the film is peeled off from the material belt 313 by the peeling knife 316 and falls onto the placement table 317 for the suction cup 325 to pick up.

[0040] The multi-axis film bonding device 32 includes a film transport bracket 321 mounted on the machine base 1, a film X-axis linear module 322 mounted on the film transport bracket 321, a film Y-axis module 323 mounted on the film X-axis linear module 322 and driven by the film X-axis linear module 322 to move back and forth, a film Z-axis module 324 mounted on the film Y-axis module 323 and driven by the film Y-axis module 323 to move, a suction cup 325 mounted on the film Z-axis module 324 and driven by the film Z-axis module 324 to lift and lower to bond the film to the surface of the product 100, and a vision inspection camera 326 mounted on the film Z-axis module 324 for detecting whether the film is properly bonded. Here, the suction cup 325 achieves three-axis movement adjustment through the film X-axis linear module 322, film Y-axis module 323 and film Z-axis module 324, so as to move back and forth between the rotating disk 11 and the film feeding mechanism 31 to pick up the film for attachment, and the visual inspection camera 326 assists in positioning so that the suction cup 325 can accurately attach the film to the surface of the product 100.

[0041] Preferably, the visual positioning device 33 includes a camera bracket 331 mounted on the machine base 1 and a positioning camera 332 mounted on the camera bracket 331.

[0042] Combination Figure 9 As shown, the present invention also includes: an automatic unloading module 4, which is set on the machine base 1 and used to unload the product 100 from the rotating disk 11; the automatic unloading module 4 includes a finished product frame 41 set on the machine base 1 and used to place the product 100, and an unloading robot 42 set on the machine base 1 and used to transfer the product 100 from the rotating disk 11 to the finished product frame 41.

[0043] In addition, a protective cover 5 is installed on the machine 1, which can effectively prevent external dirt and foreign objects from falling into the equipment.

[0044] In summary, this invention completely changes the traditional method of manually assembling rubber rings. The rubber ring assembly mechanism 2 set on the machine 1 replaces manual assembly of the rubber rings, reducing the need for manpower and significantly lowering labor costs. Furthermore, the rubber ring lifting drive module 232 and the opening and closing module 231 drive the rubber ring assembly clamp 235 to lift and pass through the product 100, clamp the rubber ring, and pull it down for assembly. This is more stable and efficient than manual assembly, eliminating problems such as missing parts and incomplete assembly. It is also applicable to the assembly of rubber rings of different sizes and diameters. In addition, compared with the existing structure, the present invention uses a mechanical clamp instead of a human hand, which effectively avoids the risk of pinching fingers; and the first clamping arm 237 and the second clamping arm 238 of the rubber ring assembly clamp 235 can open after closing and passing through the product 100 to clamp the rubber ring and deform it so that it can be pulled down and assembled into the mounting hole 101 of the product 100. For plate-shaped products 100 with mounting holes 101, the rubber ring can also be effectively passed through the product 100 for assembly, and the assembly is efficient and stable.

[0045] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of the present invention.
