Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of harmonic reduction, in particular to a harmonic wave generator automatic cleaning device. BACKGROUND

[0002] The harmonic wave generator is a key component in the harmonic reducer, and the conventional cleaning of the harmonic wave generator is manually washed, and the cleaning efficiency is not high, and the consistency of cleanliness is not good. If the harmonic wave generator is directly thrown into the ultrasonic cleaner, it will cause collision and wear between the harmonic wave generators, and the dust in the gap of the harmonic wave generator also needs to be cleaned during cleaning, and if it is directly thrown into the ultrasonic cleaner, it will cause the cleaning of the gap to be impossible. Therefore, a harmonic wave generator automatic cleaning device is needed, which can clean the harmonic wave generator by ultrasonic wave, replace the cleaning method of workers, and also clean the dust in the gap of the harmonic wave generator. SUMMARY

[0004] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows: the present application provides a harmonic wave generator automatic cleaning device, which comprises an ultrasonic cleaner, a telescopic gripper, an electric control lifting support, a rotary drive mechanism, a suction clamping seat and a rotary seat.

[0005] Preferably, the rotary drive mechanism includes multiple gears and two single-sided rotary mechanisms. The multiple gears are fixedly mounted on multiple rotating seats, and the two single-sided rotary mechanisms are located on both sides of the ultrasonic cleaner. The two single-sided rotary mechanisms are used to drive the gears to rotate in the same direction. Each single-sided rotary mechanism includes a rack, a rocker arm, a hinged rod, a rotary mechanism, a sliding sleeve, and a rotary rod. The rack is horizontally slidably mounted on the electrically controlled lifting bracket and meshes with multiple gears. One end of the hinged rod is hinged to the rack, and the other end of the hinged rod is hinged to one end of the rocker arm. The middle part of the rocker arm is hinged to the electrically controlled lifting bracket.

The rotary mechanism is fixedly mounted on the electrically controlled lifting bracket, and the rotating end of the rotary mechanism is fixedly connected to the rotary rod.

[0006] Preferably, the telescopic gripper includes two telescopic clamping arms, which are respectively fixedly installed on both sides of the ultrasonic cleaner. The two telescopic clamping arms are used to synchronously clamp the wave generator, thus fixing the outer edge of the wave generator. Each telescopic clamping arm includes a sliding clamping arm, a contact spring, a cam, a rotary motor, and a contact plate. The sliding clamping arm is horizontally slidable inside the ultrasonic cleaner. The contact plate is located on the outside of the ultrasonic cleaner and is fixedly installed on the sliding clamping arm. The outer edge of the cam abuts against the contact plate. The cam is fixedly installed on a rotating column. The column is rotatably mounted on the outer edge of the ultrasonic cleaner, and the rotary motor is fixedly mounted on the outer edge of the ultrasonic cleaner. The output end of the rotary motor is fixedly connected to the rotating column. The contact spring is used to apply an elastic force away from the ultrasonic cleaner to the sliding clamping arms. A recessed groove is provided on the cam. When the contact plate abuts against the groove wall, the rack drives the gear to rotate in the opposite direction. At this time, the two sliding clamping arms release their grip on the outer edge of the wave generator. When the contact plate abuts against the outer edge of the cam, the rack drives the gear to rotate in the forward direction. At this time, the two sliding clamping arms grip the outer edge of the wave generator.

[0007] Preferably, the rotating mechanism is a hexagonal sliding column, the top of which is provided with a hexagonal sliding groove for vertical sliding of the rotating column, the recessed groove occupies an angle greater than degrees on the cam, and the recessed groove and the outer edge of the cam are rounded.

[0008] Preferably, the sliding clamping arm includes a connecting plate, two guide posts, a mounting plate, and multiple clamping blocks. The multiple clamping blocks are all fixedly mounted on the connecting plate. One end of each of the two guide posts is fixedly connected to the connecting plate, and the other end of the guide posts extends out of the ultrasonic cleaner. The outer edge of the guide posts is slidably connected to the outer edge of the ultrasonic cleaner. The mounting plate is fixedly connected to the other end of the guide posts. A contact spring is sleeved on the outer edge of the guide posts. The contact spring is used to push the mounting plate to move outward. A contact plate is fixedly mounted on the mounting plate.

The retaining ring is fixedly installed on the outer edge of the plug, and the top of the wave generator is in contact with the bottom of the retaining ring.

[0011] Preferably, the rotary drive mechanism includes a second mounting plate, a slide rail, and multiple slide blocks. The slide rail is fixedly mounted on the electrically controlled lifting bracket, and the multiple slide blocks are horizontally slidably mounted on the slide rail. The second mounting plate is fixedly connected to the multiple slide blocks, and the rack is fixedly connected to the second mounting plate.

[0012] The beneficial effects of this invention are as follows: This automatic cleaning device for harmonic wave generators uses a telescopic clamp to hold the outer edge of the wave generator, and then uses a rotary drive mechanism to drive the inner edge of the wave generator to rotate, so that the inner and outer rings of the wave generator rotate relative to each other. Dust in the gaps of the wave generator can come into contact with the ultrasonic waves through this rotation, allowing the dust in the gaps to be discharged. Furthermore, the wave generator is held firmly by a suction holder, which restricts the position of the wave generator and prevents collisions between multiple wave generators.

[0013] Furthermore, this device avoids wire tangling when using electromagnets, and allows the inner and outer circles of the wave generator to rotate in only one direction, improving the cleaning effect for smaller wave generators. For larger wave generators, it can alternate between forward and reverse rotation, further enhancing the cleaning effect. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example: This invention provides an automatic cleaning device for harmonic wave generators, such as... Figures 1-2As shown, the device includes an ultrasonic cleaner 1, a telescopic gripper 2, an electrically controlled lifting bracket 3, a rotary drive mechanism 4, a suction cup 5, and a rotating base 7. The ultrasonic cleaner 1 contains cleaning fluid and can emit ultrasonic waves into the cleaning fluid, causing the cleaning fluid to vibrate, thus cleaning the wave generator 6. The electrically controlled lifting bracket 3 is fixedly installed on the outer edge of the ultrasonic cleaner 1, and the rotating base 7 is fixedly installed on the lifting base of the electrically controlled lifting bracket 3. The suction cup 5 is fixedly installed on the bottom of the rotating base 7 and is used to clean the wave generator 6. The inner edge of the wave generator 6 is clamped, and the electrically controlled lifting bracket 3 is used to drive the wave generator 6 installed on the suction holder 5 into the cleaning solution. There are multiple rotating seats 7 and suction holders 5, which allow the device to clean multiple wave generators 6 simultaneously. The rotary drive mechanism 4 is fixedly installed on the electrically controlled lifting bracket 3 and is used to drive multiple rotating seats 7 to rotate simultaneously. The telescopic gripper 2 is fixedly installed on the ultrasonic cleaner 1 and is used to clamp the outer edge of multiple wave generators 6. First, the workers clamp the multiple wave generators 6 onto the multiple suction holders 5. The suction holders 5 fix the inner edge of the wave generators 6 by electromagnetic attraction. Then, the electrically controlled lifting bracket 3 drives the wave generators 6 into the cleaning solution. The telescopic gripper 2 then clamps the multiple wave generators 6, and then the rotary drive mechanism 4 rotates them. This causes the inner edges of the multiple wave generators 6 to rotate, while the outer edges of the wave generators 6 cannot rotate because they are clamped by the telescopic gripper 2.

[0024] However, if the rotary drive mechanism 4 drives the rotating seat 7 to rotate in the same direction continuously, the wires on the suction cup 5 will continuously become tangled on the rotating seat 7. Therefore, a reciprocating rotation of the motor can be used to avoid wire tangling, but over time, this will damage the rotor inside the motor. Therefore, if... Figure 3As shown, the rotary drive mechanism 4 includes multiple gears 4a and two single-sided rotary mechanisms. The gears 4a are fixedly mounted on multiple rotating seats 7. When the gears 4a rotate, they drive the rotating seats 7 to rotate synchronously. The two single-sided rotary mechanisms are located on both sides of the ultrasonic cleaner 1. The two single-sided rotary mechanisms are used to drive the gears 4a to rotate in the same direction. Each single-sided rotary mechanism includes a rack 4b, a swing arm 4c, a hinge rod 4d, a rotary mechanism 4e, a sliding sleeve 4f, and a rotating rod 4h. 4b is horizontally slidably mounted on the electrically controlled lifting bracket 3. The rack 4b meshes with multiple gears 4a. One end of the hinge rod 4d is hinged to the rack 4b, and the other end of the hinge rod 4d is hinged to one end of the swing rod 4c. The middle part of the swing rod 4c is hinged to the electrically controlled lifting bracket 3. The sliding sleeve 4f is fitted onto the other end of the swing rod 4c. One end of the rotating rod 4h is rotatably connected to the bottom of the sliding sleeve 4f. The rotating mechanism 4e is fixedly mounted on the electrically controlled lifting bracket 3, and the rotating end of the rotating mechanism 4e is fixedly connected to the rotating rod 4h. The controller controls the rotation mechanism 4e to rotate, which in turn drives the rotating rod 4h to rotate. The rotating rod 4h, in turn, causes the sliding sleeve 4f to slide along the rocker arm 4c. Simultaneously, the rocker arm 4c swings along the hinge point. This swinging motion pulls the rack 4b, which in turn pushes the rack 4b to slide horizontally. The rack 4b, through meshing, drives the gear 4a to rotate. Because the rack 4b reciprocates, the gear 4a rotates reciprocally. Multiple gears 4a simultaneously drive multiple rotating seats 7 to rotate simultaneously.

[0025] When the above-described method is rotated, the wave generator 6 can reciprocate, thus cleaning the wave generator 6. However, sometimes wave generators 6 of different specifications require continuous unidirectional rotation for cleaning. Whether the wave generator 6 rotates in the same direction or reciprocates depends mainly on the size of the wave generator 6. For larger wave generators 6 with more dirt, reciprocating rotation is required, while smaller wave generators 6 rotate in the same direction. Therefore, the telescopic gripper 2 includes two telescopic clamping arms, which are fixedly installed on both sides of the ultrasonic cleaner 1. The two telescopic clamping arms are used to synchronously abut and clamp the wave generator 6, thereby fixing the outer edge of the wave generator 6. Each telescopic clamping arm includes a sliding clamping arm 2a, an abutting spring 2b, a cam 2c, a rotary motor 2d, and a contact plate 2e. The sliding clamping arm 2a is horizontally slidably installed inside the ultrasonic cleaner 1. The contact plate 2e is located on the outside of the ultrasonic cleaner 1 and is fixedly installed on the sliding clamping arm 2a. The outer edge of the cam 2c abuts against the contact plate 2e and is fixedly installed on the rotating column 2f. The rotating column 2f is rotatably installed on the outer edge of the ultrasonic cleaner 1. The rotary motor 2d is fixedly installed on the outer edge of the ultrasonic cleaner 1, and the output end of the rotary motor 2d is fixedly connected to the rotating column 2f. The abutting spring 2b is used to apply an elastic force away from the ultrasonic cleaner 1 to the sliding clamping arm 2a. The cam 2c has a recessed groove 2h.

[0026] By controlling the rotation of the rotary motor 2d, the rotary motor 2d will drive the sliding clamping arm 2a to move, so that the sliding clamping arm 2a can clamp the wave generator 6.

[0027] When the contact plate 2e abuts against the groove wall of the recessed groove 2h, the rack 4b drives the gear 4a to rotate in the opposite direction. At this time, the two sliding clamping arms 2a release their clamping on the outer edge of the wave generator 6. The release process is achieved by the contact spring 2b pushing the sliding clamping arms 2a to move.

[0028] When the contact plate 2e abuts against the outer edge of the cam 2c, the rack 4b drives the gear 4a to rotate in the forward direction. At this time, the two sliding clamping arms 2a clamp the outer edge of the wave generator 6. The clamping process is achieved by the cam 2c pushing the contact plate 2e to move, so that the sliding clamping arms 2a clamp the outer edge of the wave generator 6.

[0029] If the rotation of the rotating base 7 and the clamping of the outer edge of the wave generator 6 are controlled by a controller, this process will be difficult to achieve because the rotational drive mechanism 4 drives the rotating base 7 to rotate in the opposite direction by 90 degrees, while the rotational drive mechanism 4 drives the rotating base 7 to rotate in the forward direction by 270 degrees, and the speed of the reverse rotation is relatively fast. Therefore, if... Figure 4As shown, the rotating mechanism 4e is a hexagonal sliding column. The top of the rotating column 2f has a hexagonal groove for vertical sliding. The recessed groove 2h occupies an angle greater than 90 degrees on the cam 2c, and the outer edges of the recessed groove 2h and the cam 2c are rounded. The movement of the cam 2c and the rotating rod 4h are connected, ensuring that the clamping process is connected to the forward rotation of the rotating seat 7, and the loosening process is connected to the reverse rotation of the rotating seat 7, making this process easy to achieve. Furthermore, this structural design allows for adjustment of the rotation speed of the rotating seat 7 at any time, enabling a greater rotational force to drive the wave generator 6 to rotate in the opposite direction for better cleaning of dirt.

[0030] like Figure 4 As shown, the sliding clamping arm 2a includes a connecting plate 2a2, two guide posts 2a3, a mounting plate 2a4, and multiple clamping blocks 2a1. The clamping blocks 2a1 are all fixedly mounted on the connecting plate 2a2. One end of each guide post 2a3 is fixedly connected to the connecting plate 2a2, and the other end of each guide post 2a3 extends out of the ultrasonic cleaner 1, with its outer edge slidably connected to the outer edge of the ultrasonic cleaner 1. The mounting plate 2a4 is fixedly connected to the other end of each guide post 2a3. A contact spring 2b is sleeved on the outer edge of each guide post 2a3 and is used to push the mounting plate 2a4 outward. A contact plate 2e is fixedly mounted on the mounting plate 2a4. When the contact plate 2e is pushed, it will push the connecting plate 2a2 through the mounting plate 2a4, allowing the multiple clamping blocks 2a1 to clamp the outer edge of the wave generator 6. For more practical needs, the length of the clamping block 2a1 can be changed to accommodate wave generators 6 of different sizes, and the length of the guide post 2a3 can also be adjusted. By pushing the mounting plate 2a4 with the abutment spring 2b, the clamping block 2a1 can be released from its grip on the outer edge of the wave generator 6.

[0031] like Figure 1 As shown, the electrically controlled lifting support 3 includes a frame 3b and four hydraulic push rods 3a. The four hydraulic push rods 3a are all fixedly installed on the outer edge of the ultrasonic cleaner 1, and the frame 3b is fixedly installed on the top of the four hydraulic push rods 3a. By controlling the four hydraulic push rods 3a to work synchronously, the four hydraulic push rods 3a can drive the frame 3b to move up and down synchronously.

[0032] like Figure 5As shown, the magnetic retainer 5 includes a pin 5a, an electromagnet 5b, and a retaining ring 5c. The electromagnet 5b is fixedly installed at the bottom of the rotating base 7. The pin 5a is fixedly connected to the electromagnet 5b, and the magnetic force of the electromagnet 5b is transmitted to the pin 5a. When the wave generator 6 is fitted onto the pin 5a, the inner edge of the wave generator 6 is attracted tightly to the outer edge of the pin 5a. The retaining ring 5c ​​is fixedly installed on the outer edge of the pin 5a, and the top of the wave generator 6 contacts the bottom of the retaining ring 5c. When the wave generator 6 is installed, the electromagnet 5b attracts the wave generator 6, allowing it to be tightly attracted onto the pin 5a. When the pin 5a rotates, it drives the inner edge of the wave generator 6 to rotate.

[0033] like Figure 6 As shown, the rotary drive mechanism 4 includes a mounting plate 4k, a slide rail 4s, and multiple slide blocks 4j. The slide rail 4s is fixedly mounted on the electrically controlled lifting bracket 3, and the multiple slide blocks 4j are horizontally slidable on the slide rail 4s. The mounting plate 4k is fixedly connected to the multiple slide blocks 4j, and the rack 4b is fixedly connected to the mounting plate 4k. When the mounting plate 4k is driven, it drives the rack 4b to slide horizontally, and the mounting plate 4k drives the slide blocks 4j to slide horizontally along the slide rail 4s, thus enabling the rack 4b to slide horizontally.

[0034] In use, workers first clamp multiple wave generators 6 onto multiple suction holders 5. The suction holders 5 secure the inner edges of the wave generators 6 via electromagnetic attraction. Then, the electrically controlled lifting bracket 3 drives the wave generators 6 into the cleaning fluid. Next, the telescopic grippers 2 clamp the multiple wave generators 6, and then the rotary drive mechanism 4 rotates them, causing the inner edges of the multiple wave generators 6 to rotate. Specifically, when the wave generators 6 rotate forward, the telescopic grippers 2 clamp the outer edges of the wave generators 6; when the wave generators 6 rotate in the reverse direction, the telescopic grippers 2 release their grip.

[0035] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
