Description

Technical Field

[0001] The present invention relates to the technical field of laser welding processing, and particularly to a fully automatic welding device for shaving blades. Background Art

[0002] A shaving blade is a tool component specifically used to assist in shaving beards. It directly contacts the beard during shaving and cuts it off. Shaving blades are divided into two types: manual and automatic. There are usually mounting holes in the center of manual shaving blades for easy installation and replacement. In manual razors, manual shaving blades mainly include flat blades and laser spot welding blades. Among them, laser spot welding blades need to be welded on a pre-processed knife holder to increase the thickness of the blade.

[0003] The patent application with the publication number CN207982547U discloses a fully automatic welding device for shaving blades, which includes a laser welding machine and a frame. The frame is arranged on one side of the laser welding machine. The frame is provided with a rotary table, processing stations, two sets of blanking stations and a touch screen box. The rotary table is arranged in the middle of the frame. The processing stations include multiple knife holder processing stations and multiple blade processing stations. The frame is also provided with multiple spreading mechanisms, welding pressing mechanisms and pre-pressing mechanisms. Multiple material placement fixtures are arranged on the rotary table.

[0004] For the fully automatic welding device for shaving blades provided by this patent, the springs between the fixed fixtures of its material placement fixtures will gradually weaken in elasticity during long-term use, and the clamping stability of the knife holder and the blade during welding will decrease during long-term operation, thereby affecting the welding quality of the blade.

Four circular through holes are opened on the top of the fixing base 411. The positions of the rectangular through holes correspond to the positions of the circular through holes on the top of the bearing plate 31. A heightening top frame 412 is fixedly connected to the top of the fixing base 411. A rectangular blind hole is opened on the top of the heightening top frame 412. Rectangular through holes are opened at the bottoms of the front and top rectangular blind holes of the heightening top frame 412.

There are two rectangular sliding grooves on each side, and the rectangular sliding grooves on each side form an inverted V shape. Four electromagnet assemblies are fixedly connected to the top of the fixing base 411. The electromagnet assemblies are electrically connected to the electric control cabinet 8 through wires;

[0052] The fixed slide plate 42 is slidably connected to the top of the fixed frame 41 and is used to place the tool holder and cooperate with the fixed frame 41 to press the blade and the tool holder. The fixed slide plate 42 includes a metal slide bar 421. The surface of the metal slide bar 421 is slidably connected to the circular through holes of the fixed base 411 and the bearing plate 31. The number of metal slide bars 421 is four. The bottom of the metal slide bar 421 is fixedly connected to the bottom of the bearing plate 31 through a spring.

A pressure sensor is embedded on the top of the linkage pressure plate 422 to sense pressure. The linkage pressure plate 422 is slidably connected to the inside of the rectangular through hole at the top of the heightening top frame 412. The distance from the top of the linkage pressure plate 422 to the top of the fixed base 411 is less than the distance from the bottom of the inner wall of the front rectangular through hole of the heightening top frame 412 to the top of the fixed base 411;

[0053] The elastic connection port 43 is slidably connected to the back of the rectangular blind hole of the heightening top frame 412. The elastic connection port 43 includes an arc-shaped connection head 431 made of rubber, which is used to seal the interface connected to the blade feeding mechanism 2 to prevent the blade from jamming and falling off. The back of the arc-shaped connection head 431 is fixedly connected with an elastic metal plate 432 made of stainless steel, which is used to push the arc-shaped connection head 431 to reset. The back of the elastic metal plate 432 is fixedly connected to the back of the rectangular blind hole of the heightening top frame 412. The front of the elastic connection port 43 is communicated with a rectangular through hole for passing the blade and the tool holder;

[0054] The fixed slide bar 44 is slidably connected to the inside of the heightening top frame 412 through a rectangular chute. The fixed slide bar 44 includes two parallel slide bars. Claw plates are fixedly connected to the front and back of the parallel slide bars of the fixed slide bar 44 for clamping the blade. The number of fixed slide bars 44 is two and they are symmetrically distributed on the front of the inner wall of the heightening top frame 412;

[0055] The sliding pressure plate 45 is slidably connected to the top of the fixed frame 41 and is used to cooperate with the passive pressing mechanism 7 to fix the blade and the tool holder during the welding process. The sliding pressure plate 45 is slidably connected to the top of the heightening top frame 412. The sliding pressure plate 45 includes a contact plate body 451. The bottom of the contact plate body 451 is slidably connected to the top of the heightening top frame 412. The top of the contact plate body 451 is communicated with a rectangular through hole. The bottom of the contact plate body 451 is fixedly connected to the top of the heightening top frame 412 through a spring. Two pressing copper blocks 452 are fixedly connected to the bottom of the contact plate body 451 and are symmetrically distributed at the bottom of the contact plate body 451. The pressing copper blocks 452 are used to press the blade and the tool holder and assist the blade in dissipating heat during the welding process;

[0056] The material transfer pipe 46 is connected to the back of the heightening top frame 412. The material transfer pipe 46 includes a pipe body 461. A rectangular through hole is connected to the front of the pipe body 461. Trapezoidal blocks are fixedly connected to both sides inside the pipe body 461. A material transfer push frame 462 is slidably connected inside the pipe body 461. The top cross-section of the material transfer push frame 462 is U-shaped, and is used to push the welded blade out of the processing seat 4 under the push of gas. The back of the material transfer push frame 462 is fixedly connected to the front of the trapezoidal block of the pipe body 461 through a spring. Circular through holes are connected to the left and right sides of the pipe body 461 and the material transfer push frame 462. The circular through hole of the pipe body 461 is close to the front of the pipe body 461, and the circular through hole of the material transfer push frame 462 is close to the back of the material transfer push frame 462;

[0057] During use, before starting processing, the tool holder is pushed into the top of the linkage pressure plate 422 through the rectangular through hole on the front of the heightening top frame 412. Since the surface height of the top of the linkage pressure plate 422 is lower than the bottom surface height of the rectangular through hole on the front of the heightening top frame 412, the tool holder cannot slide freely under the restriction of the linkage pressure plate 422 and the rectangular through hole of the heightening top frame 412;

[0058] After the equipment is started, when the processing seat 4 rotates to the back of the blade feeding mechanism 2 driven by the bearing plate 31, the arc connecting head 431 squeezes the rubber head of the rectangular pipe of the material storage box 21, and the rubber head undergoes elastic deformation. At the same time, the arc connecting head 431 slides backward and squeezes the elastic metal plate 432, thereby realizing the sealed docking of the arc connecting head 431 and the material storage box 21. Subsequently, the process of feeding the blade into the processing seat 4 in the first embodiment is executed. The blade slides through the elastic connecting port 43 through the rectangular hole of the material storage box 21 and enters the top of the tool holder carried by the linkage pressure plate 422. At this time, the pressure sensor transmits the pressure change data back to the electric control cabinet 8. The electric control cabinet 8 controls the electromagnet assembly to drive the linkage pressure plate 422 to slide upward. The linkage pressure plate 422 drives the tool holder and the blade to slide upward together, thereby squeezing the blade, the tool holder and the top of the linkage pressure plate 422 and the top of the inner wall of the heightening top frame 412 together, completing the stable fixation of the blade and the tool holder. During this process, the electric control cabinet 8 adjusts the passing current of the electromagnet assembly in real time according to the pressure data transmitted back by the pressure sensor, and then adjusts the electromagnetic force, so as to realize the real-time adjustment of the clamping force of the blade;

[0059] Subsequently, the processing seat 4 rotates past the bottom of the passive pressing mechanism 7 driven by the bearing plate 31. The contact plate body 451 slides downward under the extrusion of the passive pressing mechanism 7. The contact plate body 451 drives the pressing copper block 452 to slide downward. The bottom of the pressing copper block 452 squeezes the top surface of the blade, thereby further improving the clamping force of the equipment on the blade. When the processing seat 4 moves to the bottom of the laser welding mechanism 5, the laser welding mechanism 5 welds the blade and the tool holder. During the welding process, the heat of the blade and the tool holder is transferred to the external air through the pressing copper block 452, promoting the heat dissipation of the blade and the tool holder, and thus preventing the blade and the tool holder from being thermally deformed due to excessive temperature, affecting the welding effect;

[0060] After welding is completed, the processing seat 4 rotates to the left side of the stable discharging mechanism 6. At this time, the electric control cabinet 8 reduces the clamping of the blade finished product by the processing seat 4 by regulating the passing current of the electromagnet assembly. The material transfer push frame 462 slides to the left under the action of the high-pressure gas blown by the stable discharging mechanism 6. The material transfer push frame 462 then enters the inside of the heightening top frame 412, pushing the blade finished product to slide to the left side of the heightening top frame 412, and finally pushing the blade finished product away from the equipment. After the excess gas blown by the stable discharging mechanism 6 reaches the limit position and makes the circular through holes of the pipe body 461 and the material transfer push frame 462 coincide, it is discharged through the circular through holes of the device.

[0065] In use, after the device is started, the air pump assembly 62 is started under the control of the electric control cabinet 8, and external air is sucked into the inside of the support air tank 61. When the contact plate body 451 passes through the bottom of the trigger bent plate 72, the bottom of the trigger bent plate 72 presses the contact plate body 451, and the contact plate body 451 slides downward, thereby realizing the process of clamping the blade and the tool holder by the sliding pressing plate 45 in the second embodiment. After the machining seat 4 rotates to the bottom of the laser welding head 52, the laser welding head 52 performs laser welding on the blade and the tool holder. After the welding is completed, the machining seat 4 leaves the bottom of the trigger bent plate 72 driven by the rotation of the bearing plate 31.
