Description

Technical Field

[0001] The invention relates to the technical field of household appliance production, and in particular to an assembly device for a hair dryer. Background Art

[0002] In the production process of hair dryers, a sophisticated and efficient assembly process is the key to ensuring product quality and production efficiency. Usually, this process involves the separate processing and testing of multiple precision parts, followed by the assembly stage. These parts include but are not limited to motors, hair dryers, shafts, fan blades, control circuit boards, housings, and various connecting wires. Each component must undergo strict quality control to ensure that its performance meets the standards and can work seamlessly together to form a fully functional hair dryer.

[0003] In the assembly process, the assembly of the air cylinder, shaft and blades is particularly critical because they are directly related to the air output efficiency, noise control and service life of the hair dryer. However, in traditional production methods, the assembly of these parts often relies on fixed template structures for positioning and fixing. Although these template structures have improved the accuracy and efficiency of assembly to a certain extent, their limitations are also becoming increasingly prominent, that is, they lack flexibility and are difficult to adapt to the production needs of hair dryers of different specifications and models.

[0004] Specifically, due to the wide variety of hair dryers on the market, the diameter, length, size and shape of the wind tube may vary due to different product designs. The traditional fixed template structure is designed to adapt to a certain specification or several similar specifications of products. When it is necessary to produce hair dryers of other specifications, the entire set of templates often needs to be replaced, which not only increases production costs, but also prolongs production preparation time and reduces the flexibility and response speed of the production line.

[0005] Therefore, it is very necessary to design an automated assembly device that can improve the fit of the blower barrel and the fan blade fixing mold in the hair dryer. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0027] Embodiment: An assembly device for a hair dryer, such as Figure 1-Figure 4 As shown, it includes a base 1, and the base 1 is provided with a cross-type transmission channel with a height difference. The transmission channel is respectively equipped with a first conveyor belt 2 and a second conveyor belt 3, and the first conveyor belt 2 is located above the second conveyor belt 3. The first conveyor belt 2 and the second conveyor belt 3 are provided with equidistant adjustable platforms 5, and the first conveyor belt 2 and the second conveyor belt 3 are both provided with synchronous motors to keep the speed consistent. The first conveyor belt 2 is used to transmit the air cylinder, and the second conveyor belt 3 is used to transmit the fan blades. A mechanical arm 19 is arranged on the base 1, and the mechanical arm 19 can adopt a three-axis mechanical arm 19 equipped with an electric suction cup. The two mechanical arms 19 correspond to the first conveyor belt 2 and the second conveyor belt 3 respectively, so as to realize the automatic loading effect of automatically grabbing the air cylinder and the fan blade to the adjustable platform 5, and a lifting plate 4 driven by a cylinder is arranged in the middle of the base 1, and a top rod 402 is arranged inside the base 1. The lifting plate 4 and The push rod 402 moves in opposite directions to push the material in the adjustable support platform 5 at the overlapping position in the middle of the base 1 to be assembled. The base 1 is provided with a feeding platform 12, which is used to push the rotating shaft (the rotating shaft is the central axis of the fan blade). The feeding platform 12 corresponds to the corresponding position of the second conveyor belt 3. The adjustable support platform 5 is composed of a clamping block 6, a rack 7, a transmission gear 8 and a synchronous gear ring 9. The clamping block 6 is radially arranged and slides on the end face of the adjustable support platform 5 through a spline limit. The bottom of the clamping block 6 is fixed with a rack 7, the transmission gear 8 is rotatably connected in the adjustable support platform 5, the synchronous gear ring 9 is rotatably connected to the adjustable support platform 5, and the transmission gear 8 is meshed with the rack 7 and the synchronous gear ring 9 at the same time. When the clamping block 6 moves radially, the transmission gear 8 is driven by the rack 7 to rotate, and the transmission gear 8 rotates synchronously through the synchronous gear ring 9, so that the clamping block 6 moves synchronously to adjust the clamping range of the clamping block 6.

[0028] like Figure 4As shown, the adjustable platform 5 is provided with an adjustment component, which consists of a limit block 10, a threaded rod 11 and a lock 1101. The limit block 10 is fixed to the adjustable platform 5 and corresponds to one of the clamping blocks 6. The threaded rod 11 is rotatably connected to the clamping block 6. The threaded rod 11 is threadedly connected to the limit block 10. A lock 1101 is provided at the end of the threaded rod 11. In this embodiment, the lock 1101 is provided with a hexagonal hole, so the staff needs to hold a hexagonal wrench of a specified specification to rotate the threaded rod 11. When the threaded rod 11 is rotated, It is able to drive the clamping block 6 to move radially, and the clamping block 6 drives the synchronous gear ring 9 to rotate through the rack 7 and the transmission gear 8, thereby driving other clamping blocks 6 to move radially synchronously. Therefore, the role of setting the adjustment component is to actively adjust the position of the clamping block 6, so as to adjust the clamping range of the adjustable base 5, that is, to adjust the fixation of wind tubes and fan blades of different specifications to achieve the effect of improving adaptability. In addition, setting the threaded rod 11 to limit the clamping block 6 can also improve the stability of the adjustable base 5 and prevent the clamping block 6 from moving disorderly.

[0029] like Figure 2 As shown, the lifting plate 4 drives the push rod 402 through the piston cylinder 401. Specifically, the push rod 402 is slidably connected in the base 1. A piston rod is provided at the bottom end of the lifting plate 4 to adjust the pressure of the piston cylinder 401. The piston cylinder 401 is connected to the push rod 402 through a sealing pipe. When the lifting plate 4 moves downward, the piston cylinder 401 can be pressurized. The piston cylinder 401 drives the push rod 402 to move upward through air pressure, so that the lifting plate 4 and the push rod 402 move in opposite directions. The push rod 402 pushes the fan blades located in the second conveyor belt 3 upward, so that the fan blades are embedded in the wind tube. The lifting plate 4 can move downward and limit the wind tube, so that the wind tube and the fan blades can be accurately docked and assembled.

[0030] like Figure 5 , Figure 6 and Figure 7As shown, it also includes a pressing block 15, a magnetic pad block 16, a telescopic push rod 13 and a material baffle plate 14. The feeding platform 12 is provided with a material trough 1201, and the material trough 1201 is provided with a through hole, which is located above the second conveyor belt 3. The pressing block 15 is fixed to the side of the lifting plate 4, and the magnetic pad block 16 is slidably connected in the feeding platform 12, specifically located above the through hole of the material trough 1201, and the magnetic pad block 16 can magnetically fix the rotating shaft at the end of the material trough 1201. When the lifting plate 4 moves downward, the pressing block 15 contacts and pushes the magnetic pad block 16 downward, and the magnetic pad block 16 pushes the magnetically attracted rotating shaft into the fan blade located on the second conveyor belt 3. The telescopic push rod 13 is connected to the side of the lifting plate 4, and the material baffle plate 14 is slidably connected in the material trough 1201. The end of the telescopic push rod 13 is rotatably connected to the material baffle plate 14, and the middle part of the material baffle plate 14 is provided with a through slot 1401. It is set to be a wedge block 1402, which can close the material trough 1201. During the downward movement of the lifting plate 4, the endmost shaft of the material trough 1201 is pushed into the fan blade. At the same time, the lifting plate 4 pushes the material blocking plate 14 to move horizontally through the telescopic push rod 13, so that the through groove 1401 part can overlap with the material trough 1201. At this time, the material trough 1201 is in an open state, and the lifting plate 4 moves upward for reset. Since an inclined guide groove is provided at the upper end of the feeding platform 12, the rotating shaft will move downward under the action of gravity, and the lifting plate 4 pulls the material blocking plate 14 to move and reset through the telescopic push rod 13. The wedge block 1402 part will block the material trough 1201, and the inclined surface part of the wedge block 1402 can push the rotating shaft in the material trough 1201, so that the endmost rotating shaft can be accurately moved to the bottom of the magnetic pad 16 for fixation, in preparation for the next rotating shaft assembly.

[0031] like Figure 8 As shown, it also includes a push rod 17 and a discharging push rod 18. The push rod 17 is rotatably connected to the side of the lifting plate 4, and the discharging push rod 18 is slidably connected in the base 1 and corresponds to the first conveyor belt 2. The push rod 17 is rotatably connected to the discharging push rod 18. A transverse push rod is arranged at the end of the discharging push rod 18. The transverse push rod can pass through the middle position of the clamping block 6 in the adjustable base 5, so as to push out the assembled wind tube, rotating shaft and fan blades, thereby realizing the function of automatic unloading.

[0032] Working principle: 1. The staff rotates the threaded rod 11 with a hexagonal wrench of a specific specification, and the threaded rod 11 can drive the clamping block 6 to move radially. The rack 7, the transmission gear 8 and the synchronous gear ring 9 cooperate with each other to make each clamping block 6 move synchronously, so as to adjust the clamping range to adapt to the wind tube and fan blade models of the production batch;

[0033] 2. Turn on the synchronous motor to drive the first conveyor belt 2 and the second conveyor belt 3 to perform intermittent transmission at the same speed with a stop time of 3 seconds. The transmission length is the spacing between the adjustable support platforms 5. Control the mechanical arm 19 to place the wind tube and the fan blade in the adjustable support platforms 5 of the first conveyor belt 2 and the second conveyor belt 3 respectively, and introduce the rotating shaft into the feeding platform 12;

[0034] 3. During the intermittent time of the intermittent transmission of the first conveyor belt 2 and the second conveyor belt 3, the lifting plate 4 is controlled by the cylinder to move downward and reset, and the lifting plate 4 drives the push rod 402 to move upward synchronously through the piston cylinder 401. The lifting plate 4 and the push rod 402 push and assemble the materials in the adjustable support 5 at the overlapping position in the middle of the base 1. Specifically, the push rod 402 pushes the fan blades located in the second conveyor belt 3 upward so that the fan blades are embedded in the wind tube. The lifting plate 4 can move downward and limit the wind tube, so that the wind tube and the fan blades can be accurately docked and assembled;

[0035] 4. During the downward movement of the lifting plate 4, the magnetic pad block 16 is pushed by the pressing block 15 to push the rotating shaft in the material trough 1201 into the fan blade of the second conveyor belt 3 (the corresponding adjustable support platform 5 is located at the upper station of the air cylinder and the fan blade docking station). When the lifting plate 4 moves upward and resets, the material blocking plate 14 pushes the rotating shaft in the material trough 1201 to feed the material, so that the rotating shaft moves accurately to the magnetic pad block 16 for the next push;

[0036] 5. During the downward movement of the lifting plate 4, the lifting plate 4 pushes the discharge push rod 18 to move horizontally through the push rod 17. The discharge push rod 18 pushes out the assembled wind tube, rotating shaft and fan blade assembly transmitted to the side of the first conveyor belt 2, thereby realizing the function of automatic unloading.
