[0001] The present invention relates to the technical field of electric toothbrush head hair implanting and soft glue equipment, and particularly relates to a flat hair elastic electric toothbrush head hair implanting and soft glue equipment. Background Art
[0002] Currently, the toothbrush production equipment uses a bobbin to move back and forth in a shuttle case for wire drawing, continuously feeding toothbrush filaments into the hair implanting nozzle, and then driving an aluminum sheet feeding mechanism by a cam mechanism to feed aluminum sheets into a slicing knife box for slicing, and then implanting them into each hole of the toothbrush head together with each bundle of toothbrush filaments in sequence.

At the same time, defective products will cause the entire toothbrush to be scrapped, increasing production costs. For toothbrush production processes with different toothbrush filaments, it will be even more complicated, restricting the number, length, color, and shape of the blank materials for a single toothbrush head. The types of toothbrushes that can be produced are few, the hair density is relatively low, and the single-bundle elastic swing of the hair bundle cannot be achieved. Summary of the Invention

On the top of the bristle implanting machine base 3, there is a bristle picking mechanism 6;
[0025] Through the above embodiments, after the toothbrush bristles are manually placed, the pick-up tray automatically picks up the toothbrush bristles. The toothbrush bristles are sucked into the anti-static tube by means of vacuum extraction. The toothbrush bristles are integrated by the core mechanism and sucked into the toothbrush blade holes. After shaping, and finally high-temperature sol is used to weld the roots of the bristles into the toothbrush head blade. The bristles cooled down after being processed by the hot melt technology will be very stable, and the bristles will not fall off easily. After assembling the sub-carrier and the mother carrier, they are placed in the two-color injection molding machine 1 for injection molding;
[0026] The brush wire taking mechanism 6 is provided with a synchronous rotating mechanism composed of a servo, a reducer and a synchronous wheel and synchronous belt, and a toothbrush wire taking disc is installed on the top of each synchronous wheel, and a certain number of super semicircular holes of different sizes are arranged on the circumference of the disc. Two mounting plates for inserting anti-static tubes are arranged on the top of the brush wire planting mechanism 11, and two toothbrush wire planting integrated mold plates are arranged at the top center position of the brush wire planting mechanism 11. A waste blowing cleaning mechanism is installed on the side of the brush wire planting mechanism 11, and a mold plate with a hole shape to prevent the toothbrush head hole shape is arranged at the bottom of the brush wire planting mechanism 11. Shaking carrier cylinders are installed on both sides of the brush wire planting mechanism 11. A vacuum pump is provided at the bottom of the vacuum system 4 to connect the filter, and one end of the filter is connected to a pressure pipe through an angle seat valve. A lifting cylinder is provided on the top of the angle seat valve, and a pipe joint fixing and a sealing rubber pad are provided between the lifting cylinder and the angle seat valve. The shaping mechanism 10 is controlled by the angle seat valve and the solenoid valve at the bottom to control the blowing and suction, and the cylinder is pressed against the carrier by the sealing ring to drive the shaping. The mechanism 10 is lifted and lowered, and the rotating mechanism on the side switches the cavity position of the carrier. The lifting cylinder on the top controls the lifting height of the toothbrush filament during shaping. The hot cutting mechanism 9 is controlled by the servo motor and the KK module to control the shift of the cutter. The lifting cylinder controls the up and down position of the cutter, and the temperature of the heating core is controlled by the thermostat at 700°C. The shaped toothbrush filaments and the toothbrush head are welded together. The artificial assembly line consists of the first belt line, the second belt line and the third belt line. The first belt line returns the sub-carrier to the hair transplanting machine, the second belt line returns the mother carrier to the manual, and the third belt line transports the assembled carrier to the injection molding machine. Two sets of molds are provided in the two-color injection molding machine 1, one of which is for producing brush handles and the other is for injection molding soft glue. The brush filament taking mechanism 6 includes a hair pushing mechanism 61, and a hair holding mechanism 62 is provided on one side of the hair pushing mechanism 61, and a rotating hair taking disk 63 is provided on one side of the hair holding mechanism 62, and a tube suction mechanism 64 is provided on one side of the rotating hair taking disk 63;
[0027] Through the above embodiments, the vehicle loading mechanism 12 and the unloading mechanism drive the PPU to displace by a servo motor, adjust the angle by a rotary cylinder, pick and place the toothbrush assembly by a gripper cylinder, and the retainer / slice head loading mechanism 5 is fed by a vibrating disk, stored by a linear vibrator, the feeding cylinder ejects for feeding, the cutting cylinder punches, the servo motor displaces for feeding, the discharging cylinder demolds and places it into the vehicle. The brush wire picking mechanism 6 picks a certain amount of bristles from the bobbin containing bristles every time the disk rotates one circle, and the operator manually places the toothbrush wires cut to a fixed length into the bobbin, and presses the toothbrush wires tightly with a long-stroke pen rod cylinder. As the toothbrush wires in the bobbin decrease, the cylinder will gradually retract, always driving the pressing mechanism to press the toothbrush wires tightly. When feeding is required, as long as the operator presses the manual pressing valve, the cylinder can be easily pulled open, and the toothbrush wires can be placed into the bobbin. There is a toothbrush wire flattening mechanism above the bobbin to pat the toothbrush wires flat. The number of bobbins is determined by the number of types of toothbrush wires required for the toothbrush head. The servo motor drives the synchronous pulley set and the material tray to rotate one circle, picks the toothbrush wires from the bobbin. There are baffles with the same thickness on the circumference of the material tray to prevent the toothbrush wires picked by the material tray from leaking. At the same time, a 400w servo motor is selected, the circumferential diameters of the material tray and the baffle are the same, there are unequal numbers of material taking holes on the material tray, the central angle of the material taking holes is 240°, and the diameter size is adapted to the number of toothbrush wires required on the toothbrush head. Therefore, when changing products, only the corresponding material taking tray needs to be replaced. The synchronous belt pulley should have enough meshing teeth with the synchronous belt to make the wrap angle 120°. After the brush material tray picks the toothbrush wires, the toothbrush wire suction mechanism moves forward to directly above the toothbrush wires, the lifting cylinder moves down, covers each bundle of toothbrush wires in the material taking tube, and is sucked away by the vacuum system 4. The cylinder returns to the origin. The inner diameter of the material taking tube has two types: φ3.0mm and φ2.5mm. At the same time, when the toothbrush wire implanting mechanism 11 works, the die plate fits and moves down synchronously under the push of the cylinder to tightly press against the toothbrush head. The toothbrush wires are integrated into the toothbrush head through the holes in the die plate. The left and right vibrating vehicle cylinders act frequently to smoothly insert the toothbrush wires into the toothbrush head. After the die plate separates, the cleaning mechanism moves and descends to blow away the residual toothbrush wires in the holes. The anti-static tube connects the brush wire picking mechanism 6 and the toothbrush wire implanting structure. There are two sizes of anti-static tubes, namely anti-static tubes with an inner diameter of φ2.5mm and an outer diameter of φ3.3mm and an inner diameter of φ3.0mm and an outer diameter of φ4.0mm, and the number of inserted tubes corresponds to the toothbrush holes of the toothbrush head. The tubes are fixed by the top two layers of plates, and the clearance between the tubes and the holes in the fixing plate is 0.05mm. The holes in all die plates are larger at the top and smaller at the bottom, and the holes on the two mating surfaces are slightly smaller at the top and slightly larger at the bottom, reducing the chance of hair clogging. The holes in the topmost fixing plate are relatively dispersed. Through a 5-degree inclination angle, the holes are gradually converged towards the middle, so that the holes on the last plate are directly above the corresponding holes on the toothbrush head. The shape of the holes also gradually changes from the circular holes in the topmost layer to the same shape as the holes on the toothbrush head. The slide plate of the carrier has two cavities. At the station of implanting toothbrush filaments, the cavity with a sieve and a fine metal mesh works to ensure ventilation and prevent the toothbrush filaments from leaking away during vacuum pumping. The shaking carrier cylinder is controlled by a high-speed solenoid valve. The response time of the solenoid valve is 20 ms, and the action frequency is 7 Hz. The slide plate of the carrier is shaken slightly, so as to assist the toothbrush filaments to be smoothly inserted into the toothbrush head. The slide plate of the carrier has two cavities. At the hair implanting station, the left cavity of the carrier is used. There is a layer of breathable mesh below and a fine metal sand mesh is padded, so as to ensure ventilation and prevent the toothbrush filaments from leaking. The top of the carrier is a small cover plate imitating the holes on the toothbrush head. The aperture size is 0.05 smaller than the holes on the toothbrush head. The cavity hole size on the slide plate is 0.03 MM smaller than the aperture of the cover plate, ensuring that the end of the toothbrush filament is slightly contracted after being inserted into the toothbrush piece. The depths of the cavity holes in the slide plate are different, and the depths of each point in a single hole can also be different. When manufacturing a toothbrush designed according to ergonomics, when replacing the product, only the cavity slide plate and the cover plate of the carrier need to be replaced. The vacuum pump is selected with a vacuum degree of 0.1 mbar and an exhaust volume of 150 m. 3 / h. The main air circuit uses a DN50 normally closed one-way angle seat valve, and the branch air circuit uses a DN15 normally closed one-way angle seat valve. When the brush wire taking mechanism 6 takes the toothbrush wire, the lifting cylinder rises and is pressed against the bottom of the carrier by the sealing rubber ring. The one-way valve opens after receiving the signal. Under the action of the internal and external air pressure difference, each bundle of toothbrush wire is drawn into the toothbrush piece through the anti-static tube and the mold in turn. The bottom of the shaping mechanism 10 is an air blowing and suction mechanism. After the carrier and the product are in place, the lifting cylinder rises, the sealing ring is pressed against the carrier, and the air blowing valve sprays air evenly through the rotating nozzle to blow the toothbrush wire to the upper material blocking mechanism position. The carrier slide switches the cavity, the branch one-way angle seat valve opens, and the vacuum system 4 is connected. At the same time, the cylinder is pressed down to suck the blown toothbrush wire into the carrier cavity. The hot cutting mechanism 9 is controlled by the servo The motor and KK module control the shifting and lifting cylinder of the cutter to control the up and down position of the cutter, and the temperature controller controls the temperature of the heating core at 700℃ to weld the shaped toothbrush wire and the toothbrush head together. The hot stamping mechanism 8 controls the lifting and lowering displacement of the riveting through the brake servo and the KK module. The temperature controller controls the temperature of the heating core at 900℃ to weld the shaped toothbrush wire and the toothbrush head together. The 800W high-power heating core is used to quickly heat the welding head to 900 degrees Celsius, and the upper surface of the toothbrush piece and the toothbrush wire is quickly melted and welded with high temperature. The temperature is stabilized within 900℃ through the intelligent temperature controller. At the same time, the fixed workpiece above the welding head is cooled by water through a water cooler. The KK module is set with three working positions, a high-speed moving position, a medium-speed moving position, and a slow moving position when approaching the product.
[0028] Working principle: When the present invention is in use, the carrier loading mechanism 12 and the unloading mechanism drive the displacement of PPU through the servo motor, and the rotating cylinder adjusts the angle at the same time. The clamping claw cylinder is responsible for taking and placing the toothbrush assembly. The toothbrush assembly is fed through the retaining ring / piece head loading mechanism 5 and the vibration disk for feeding, and the vibration storage material is stored. The dividing cylinder pushes out the divided material, and the cutting cylinder performs the stamping operation. The servo motor drives the feeding device to move, and the unloading cylinder is responsible for demolding and placing the material into the carrier. The brush wire taking mechanism 6 uses the middle disc to rotate one circle each time to obtain a certain amount of hair from the bobbin case containing the hair. At the same time, the fixed-length cut toothbrush wire is manually placed into the bobbin case, and the long-stroke pen cylinder is used to press the toothbrush wire. As the toothbrush wire in the bobbin case decreases, the cylinder will gradually retract to ensure that the clamping mechanism continues to press the toothbrush wire.
[0029] When feeding is required, manually press the manual pressure valve to easily pull the cylinder and place the toothbrush filaments into the shuttle. A toothbrush filament leveling mechanism is set above the shuttle, and the toothbrush filaments are leveled and arranged by patting. The number of shuttles is determined by the type of toothbrush filaments required for the toothbrush head. The servo motor drives the synchronous pulley set and the material tray to rotate one circle to brush the toothbrush filaments from the shuttle. A baffle of the same thickness is equipped on the outer circumference of the material tray to ensure that the toothbrush filaments taken out from the material tray will not leak. The servo motor is selected with a power of 400W. The circumferential diameters of the material tray and the baffle are the same. Multiple material taking holes are provided on the material tray, and the central angle of the material taking holes is 240°. The aperture size is adapted to the number of toothbrush filaments required for the toothbrush head. When replacing the product, the user only needs to replace the corresponding material taking tray. There should be enough meshing teeth between the synchronous belt pulley and the synchronous belt to ensure a wrap angle of 120°;
[0030] After brushing the toothbrush filaments, the toothbrush filament suction mechanism moves forward to directly above the toothbrush filaments, and the lifting cylinder moves down to cover each bundle of toothbrush filaments into the material taking tube, and then sucks them away through the vacuum system 4. The cylinder returns to its original position. The inner diameter of the material taking tube provides two specifications, namely φ3.0mm and φ2.5mm. At the same time, when the toothbrush filament implanting mechanism 11 works, the die plate closely adheres and moves down synchronously under the push of the cylinder to ensure that the toothbrush filaments are integrated into the toothbrush head through the die plate holes. The left and right jitter carrier cylinders are controlled by high-speed solenoid valves, with a response time of 20ms and an action frequency of 7HZ, slightly vibrating the carrier slide plate to facilitate the smooth insertion of the toothbrush filaments into the toothbrush head. After the die plate is separated, the cleaning mechanism moves and descends to remove the residual toothbrush filaments in the holes by blowing. The anti-static tube connects the toothbrush filament taking and implanting structures. The anti-static tube is divided into two sizes, with an inner diameter of φ2.5mm and an outer diameter of φ3.3mm and an inner diameter of φ3.0mm and an outer diameter of φ4.0mm. The number of inserted tubes matches the number of toothbrush holes in the toothbrush head. The tubes are fixed by the upper two layers of plates, and the clearance between the tubes and the holes in the fixed plate is 0.05mm;
[0031] All the die plate holes are designed in the shape of larger at the top and smaller at the bottom, and the holes on the fitting surface are in the form of smaller at the top and slightly larger at the bottom to reduce the risk of hair clogging. The hole positions on the topmost fixed plate are relatively scattered, and are gradually converged to the center of the plate at a 5-degree inclination angle to ensure that the holes on the last plate accurately correspond to the toothbrush holes on the toothbrush head. The shape of the holes gradually transitions layer by layer, changing from the round holes on the topmost layer to the same shape as the holes on the toothbrush head. There are two cavities in the carrier slide plate. The cavity with a breathable net and a fine metal net is used at the toothbrush filament implanting station to ensure good ventilation and prevent the toothbrush filaments from leaking during vacuum extraction. At the hair implanting station, the left cavity of the carrier is used, and a breathable net and a fine metal sand net are placed below to ensure good air permeability;
[0032] The top of the carrier is equipped with a small cover plate imitating the hole of the toothbrush head. Its aperture size is slightly smaller than the hole of the toothbrush head (0.05mm smaller). The cavity hole size on the slide plate is even smaller (0.03mm smaller), ensuring that the end of the toothbrush wire is slightly contracted after insertion. The depth of the cavity hole in the slide plate is different, and the depth of each point can be different according to the design requirements. The design of the carrier cavity fully considers the principle of ergonomics, which is convenient for the insertion and fixation of the product. When replacing the product, only the carrier cavity slide plate and cover plate need to be replaced;
[0033] The vacuum pump is configured with a vacuum degree of 0.1 mbar and an exhaust volume of 150 m 3 / h, the main air circuit adopts DN50 normally closed one-way angle seat valve, and the branch air circuit adopts DN15 normally closed one-way angle seat valve. After brushing the brush wire, the lifting cylinder rises, and the sealing rubber ring is close to the bottom of the carrier. The one-way valve opens after receiving the signal. Under the action of the internal and external air pressure difference, each bundle of toothbrush wire is sucked into the toothbrush piece through the anti-static tube and the mold. The bottom of the shaping mechanism 10 is equipped with a blowing and suction device. After the carrier and the product are in place, the lifting cylinder rises and presses the sealing ring. The blowing valve evenly sprays air through the rotating nozzle to blow the toothbrush wire to the upper material blocking mechanism. After the carrier slide switches the cavity, the branch one-way angle seat valve opens, connects to the vacuum system 4, and presses down the cylinder to suck the blown toothbrush wire into the cavity.
[0034] The hot cutting mechanism 9 controls the displacement of the cutter through the servo motor and the KK module, the lifting cylinder controls the up and down position of the cutter, and the temperature controller ensures that the temperature of the heating core is maintained at 700°C, which is used to weld the shaped toothbrush wire and the toothbrush head together. The hot stamping mechanism 8 controls the lifting and displacement of the riveting press through the brake servo and the KK module. The temperature controller adjusts the temperature of the heating core to 900°C, and uses the 800W high-power heating core to quickly heat the welding head to 900°C. The high temperature quickly melts the surface of the toothbrush piece and the toothbrush wire to complete the welding. The intelligent temperature controller ensures that the temperature is stable within 900°C. At the same time, the workpiece above the welding head is cooled by a water cooler. The KK module is set with three working positions, a high-speed moving position, a medium-speed moving position, and a slow moving position when approaching the product, to ensure the accuracy and efficiency of the working process;
[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
