Description

Technical Field

[0001] The present invention relates to the technical field of hair dryer diode processing, and particularly to an automatic assembly device for hair dryer diodes. Background Art

[0002] A hair dryer is a cosmetic appliance used for drying and shaping hair, but it can also be used for local drying, heating, and physiotherapy in laboratories, physiotherapy rooms, industrial production, art, etc.

[0003] After retrieval, the patent of "Automatic Assembly Component for Full-Wave Rectifier Diode of Hair Dryer" with the existing publication number "CN107309646B": includes a capacitor, at least two diodes, a sleeve for covering one pin of the diode, and an extension wire connected to the sleeve. The capacitor, diode, sleeve, and extension wire are automatically riveted and connected to each other. The diodes are four and form a full-wave rectifier bridge. One pin of one diode is riveted to one pin of the capacitor, and the other pin of this diode is riveted to one pin of another diode and sleeved with a sleeve. It is processed by an automatic assembly machine, which includes multiple cylinders, a cutting knife driven by a cylinder, a feeding unit that feeds perpendicular to the cutting direction, a tape with multiple diodes arranged in the feeding unit, a diode shaping unit for shaping the pins of the cut single diode, and a rotary pick-and-place unit for selecting the shaped diodes. Among them, the pins of the diode are cut and cooperate with the shaping unit to form the diode material source of the diode component. The full-automatic production is carried out using the tape structure of the diode, reducing the use of labor and improving the assembly efficiency.

[0039] It should be noted that a through hole is opened in the inner wall of the box body 22 close to the mounting block 2. When the sliding plug 23 slides hermetically, the pressure balance in the box body 22 can be balanced.

[0040] A driving mechanism is installed in the chute 3. The driving mechanism includes a hollow rotating rod 28 rotatably connected to the inner wall of the chute 3. One end of the rotating shaft 5 extends into the hollow rotating rod 28. Two limiting grooves 29 are symmetrically opened on the inner wall of the hollow rotating rod 28. Two limiting blocks 30 are symmetrically fixedly connected to the side wall of the rotating shaft 5. The side walls of the two limiting blocks 30 are respectively slidably connected with the inner walls of the two limiting grooves 29. The upper end of the machine tool 1 is fixedly connected with a reduction motor 31. The output end of the reduction motor 31 is fixedly connected with a driving wheel 32. One end of the hollow rotating rod 28 penetrates through the side wall of the mounting block 2 and is fixedly connected with a driven wheel 33. The driving wheel 32 is connected with the driven wheel 33 through a synchronous belt. A cam 34 is fixedly connected to the side wall of the rotating shaft 5. The cam 34 slidably abuts against the side wall of the cross plate 26.

[0041] Further, drive the reduction motor 31 to rotate, drive the driving wheel 32 to rotate, drive the driven wheel 33 to rotate, and then drive the hollow rotating rod 28 to rotate, drive the rotating shaft 5 to rotate, drive the cam 34 to rotate counterclockwise (refer to the attached Figure 1 ), at this time the cam 34 will squeeze the cross plate 26, drive the cross bar 25 to move, and then drive the sliding plug 23 to slide hermetically, squeeze the air in the box body 22 into the driving box 18 through the connecting pipe 24, and then push the sliding plate 19 to slide, drive the fixing rod 20 to move, and then drive the pushing plate 21 to move, and push the diode at the bottom of the feeding box 16 to the cutting place.

[0042] A propulsion mechanism is installed on the machine tool 1. The propulsion mechanism includes a mounting frame 35 fixedly connected to the upper end of the machine tool 1. A side wall of the mounting frame 35 is fixedly connected with an electric push rod 36. The movable end of the electric push rod 36 penetrates through the side wall of the mounting frame 35 and is fixedly connected with a feeding plate 37. A conductive sheet 38 is fixedly connected to the side wall of the guide rod 15, and a conductive block 39 is fixedly connected to the inner wall of the guide groove 14. The electric push rod 36, the conductive sheet 38, the conductive block 39 and an external power supply are electrically connected through wires.

[0043] Further, the disc 6 will drive the guide rod 7 to rotate to the left end (refer to the appendix Figure 1 ), and then at this time, the moving frame 10 will drive the connecting rod 9 to slide to the leftmost end, driving the U-shaped frame 13 to move to the leftmost end. At this time, the guide rod 15 also slides to the leftmost end of the guide groove 14. At this time, the two shearing frames 12 will open, and the conductive sheet 38 will contact the conductive block 39. The electric push rod 36 will be energized and extended, driving the feeding plate 37 to move, pushing the diode to move, so that the pins of the diode move between the two shearing frames 12. The disc 6 will continue to rotate counterclockwise, driving the guide rod 7 to rotate around the center of the disc 6. At this time, the guide rod 7 will also slide on the inner wall of the moving frame 10 and push the moving frame 10 to move to the right (refer to the appendix Figure 1 ), driving the connecting rod 9 to slide to the right, driving the U-shaped frame 13 to move to the right, and then driving the guide rod 15 to move to the right. The guide rod 15 will slide to the right in the guide groove 14. At this time, the electric push rod 36 will be powered off and quickly retracted, driving the feeding plate 37 to reset. When the guide rod 15 slides in the guide groove 14, the two shearing frames 12 will rotate towards each other, and then drive the two blades 121 to approach each other to cut the pins of the diode.

[0044] It is worth mentioning that the cutting and feeding of the diode are completed by the linkage of the same series of components, which reduces the structure and makes the operation simpler. And the mechanical components are linked, so the failure rate is low.

[0045] A plurality of T-shaped rods 40 are slidably connected to the upper end of the mounting frame 35. The lower ends of the plurality of T-shaped rods 40 penetrate through the inner top of the mounting frame 35 and are commonly fixedly connected with a pressing plate 41. Second springs 42 are sleeved on the side walls of the T-shaped rods 40. Two ends of the second springs 42 are respectively fixedly connected with the inner top of the mounting frame 35 and the upper end of the pressing plate 41. The side wall of the pressing plate 41 is processed with a rounded corner.

[0046] It should be noted that the spring constant of the second spring 42 is small, and it only needs to slightly press the diode to avoid shaking when cutting the pins.

[0047] Further, when cutting the diode, the pressing plate 41 will slightly press and fix the diode under the action of the second spring 42 to avoid shaking of the diode during cutting, resulting in deviation of the cutting length of the diode pins.

[0048] The side wall of the mounting block 2 is threadedly connected with a threaded rod 43. One end of the threaded rod 43 penetrates through the side wall of the mounting block 2 and is threadedly connected with the mounting plate 4. Rotating the threaded rod 43 drives the mounting plate 4 to slide on the inner wall of the chute 3, thereby driving the scissors frame 12 to move, adjusting the distance between the scissors frame 12 and the conveying table 17, and thus adjusting the cutting length of the diode pins, facilitating the cutting of diodes that meet the requirements according to different needs, and having a wider range of applications.

[0049] A conveying device 44 and an automatic assembly machine 45 are installed on the upper end of the machine tool 1. The automatic assembly machine 45 is arranged above the conveying device 44. It should be noted that both the conveying device 44 and the automatic assembly machine 45 are prior arts, and the automatic assembly machine 45 can complete the assembly of diodes and capacitors and the riveting between wire groups.

[0050] In the present invention, first, the diodes are stacked and placed in the loading box 16. Then, the threaded rod 43 is rotated to drive the mounting plate 4 to slide on the inner wall of the chute 3, thereby driving the scissors frame 12 to move, and adjusting the distance between the scissors frame 12 and the conveying table 17, and thus adjusting the cutting length of the diode pins.

[0051] Then, the reduction motor 31 is driven to rotate, driving the driving wheel 32 to rotate, driving the driven wheel 33 to rotate, thereby driving the hollow rotating rod 28 to rotate, driving the rotating shaft 5 to rotate, and driving the cam 34 to rotate counterclockwise (refer to the appendix Figure 1 ). At this time, the cam 34 will squeeze the cross plate 26, driving the cross bar 25 to move, thereby driving the sliding plug 23 to slide in a sealed manner, squeezing the air in the box body 22 into the driving box 18 through the connecting pipe 24, thereby pushing the sliding plate 19 to slide, driving the fixed rod 20 to move, and driving the push plate 21 to move, slowly pushing the diode at the bottom of the loading box 16 towards the pressing plate 41. When the push plate 21 pushes the diode below the pressing plate 41, at this time, the pressing plate 41 will slightly press and fix the diode under the action of the second spring 42.

[0052] In addition, at this time, the disc 6 will drive the guide rod 7 to rotate to the left end (refer to the appendix Figure 1 ). Then, the moving frame 10 will drive the connecting rod 9 to slide to the leftmost end, driving the U-shaped frame 13 to move to the leftmost end. At this time, the guide rod 15 also slides to the leftmost end of the guide groove 14. At this time, the two scissors frames 12 will open, and the conductive sheet 38 will contact the conductive block 39, and the electric push rod 36 will be energized and extended, driving the loading plate 37 to move, pushing the diode to move, so that the pins of the diode move between the two scissors frames 12.

[0053] Then, the disc 6 will continue to rotate counterclockwise, driving the guide rod 7 to rotate around the center of the disc 6. At this time, the guide rod 7 will also slide on the inner wall of the moving frame 10 and push the moving frame 10 to move to the right (refer to the appendix Figure 1) It drives the connecting rod 9 to slide to the right, drives the U-shaped frame 13 to move to the right, and further drives the guide rod 15 to move to the right. The guide rod 15 will slide to the right in the guide groove 14. At this time, the electric push rod 36 will cut off the power supply and quickly contract, driving the feeding plate 37 to reset. When the guide rod 15 slides in the guide groove 14, the two shearing frames 12 will rotate towards each other, and further drive the two blades 121 to approach each other to cut the pins of the diode.

[0054] During the whole process of cutting the pins of the diode, the cam 34 will also rotate accordingly. Cooperating with the first spring 27, the sliding plug 23 will slide back to its original position. Then, the air in the driving box 18 will be drawn back through the connecting pipe 24, and the sliding plate 19 will drive the pushing plate 21 to reset.

[0055] After the cutting is completed, the disc 6 will continue to rotate. Then, the pushing plate 21 will continue to move to the right (refer to the appendix Figure 1 ), pushing the next diode to the cutting position on the conveying table 17. At this time, this diode will push the previous diode to the conveying device 44, and the conveying device 44 will convey the cut diode to the automatic assembly machine 45 for riveting and assembling the diode. In this way, the cycle repeats to feed, cut, and assemble the diodes.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
