Description

Technical Field

[0001] The present invention relates to the technical field of robotic arms, and particularly to a robotic arm for preparing optical equipment that can suppress dust and clean. Background Technique

[0002] Robotic arms are widely used in fields such as mechanical engineering and agricultural engineering, replacing humans to perform relatively complicated tasks such as high-intensity and high-precision work, greatly reducing the labor intensity of workers. Robotic arms have high operating flexibility and are controlled by a robot system. They can autonomously operate according to the planned movement trajectory of the robotic arm joint space. When preparing optical equipment, especially when using a large number of optical lenses for preparation, it is necessary to polish the edges of the optical lenses to ensure the smoothness of the edges of the optical lenses. A robotic arm can be used to grasp and transport the optical lenses for processing, accelerating the processing and preparation efficiency of the optical lenses.

[0003] Due to the different specifications and sizes of optical lenses themselves, when preparing different batches of optical lenses, the robotic arm for preparing optical equipment cannot be calibrated and locked according to the specifications and sizes of the optical lenses, and cannot lock the central position of the optical lens on the rotation axis line. As a result, when the optical lens rotates for edge polishing, the thickness of the edge polishing is different, resulting in defects in the prepared optical lens products. Moreover, during the polishing process, dust suppression and cleaning cannot be carried out, and the polished debris flutters and pollutes the surrounding environment. Therefore, a robotic arm for preparing optical equipment that can suppress dust and clean is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a robotic arm for preparing optical equipment that can suppress dust and clean, in order to solve the problems in the above background technique that the existing robotic arms for preparing optical equipment on the current market cannot be calibrated and locked according to the specifications and sizes of optical lenses, cannot lock the central position of the optical lens on the rotation axis line, resulting in different thicknesses of edge polishing when the optical lens rotates for edge polishing, resulting in defects in the prepared optical lens products, and during the polishing process, dust suppression and cleaning cannot be carried out, and the polished debris flutters and pollutes the surrounding environment.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A robotic arm for preparing optical equipment that can suppress dust and clean, including a robotic arm main body, and a robotic arm end is installed at the upper left end of the robotic arm main body;

[0006] It further includes:

[0007] An adjustment air pipe runs through the inside of the robotic arm end, and a support ring is installed on the outer side of the adjustment air pipe, and a tooth block is connected to the outer side of the support ring;

[0008] The piston is slidably connected inside the adjusting air pipe, and a powerful suction cup is connected to the lower side of the adjusting air pipe. A moving rod is connected to the upper side of the piston. At the same time, the moving rod is elastically connected to the adjusting air pipe through a compression spring;

[0009] An annular groove is formed on the outer side of the moving rod. A calibration rod is slidably connected inside the annular groove. A calibration seat is sleeved on the outer side of the calibration rod. The calibration seat and the calibration rod are fixed by bolts, and a mounting bracket is connected to the lower side of the calibration seat;

[0010] A sliding rod is connected to the outer side of the end of the robotic arm;

[0011] A motor is installed above the left of the end of the robotic arm. The output end of the motor is connected to a rotating rod. The rotating rod is rotatably connected to the end of the robotic arm. At the same time, a gear is key-connected to the outer side of the rotating rod;

[0012] An optical lens is attached to the lower side of the powerful suction cup;

[0013] A vacuum cleaner is installed on the lower right side of the main body of the robotic arm. The suction port of the vacuum cleaner is connected to a suction pipe. The other end of the suction pipe is connected to a suction hood. The suction hood is installed on the lower left side of the end of the robotic arm.

[0014] Preferably, a first magnet and a limit block are further provided on the mounting bracket:

[0015] The first magnet is connected to the lower side of the mounting bracket;

[0016] The limit block is slidably connected inside the mounting bracket. A fixing bracket is installed at the end of the limit block. A second magnet and a baffle are installed at the bottom end of the fixing bracket.

[0017] Preferably, the adjusting air pipe forms a rotating structure with the end of the robotic arm through the support ring. Tooth blocks are equidistantly distributed at the connection between the support ring and the gear. This design can drive the support ring to rotate by the rotation of the gear, thereby controlling the rotation of the adjusting air pipe.

[0018] Preferably, the vertical center line of the moving rod coincides with the vertical center line of the adjusting air pipe. The moving rod is slidably connected to the calibration rod. This design allows the moving rod and the calibration rod to slide relative to each other when the adjusting air pipe drives the moving rod to rotate. While the calibration rod is connected to the moving rod, the moving rod can rotate smoothly.

[0019] Preferably, the calibration seat and the calibration rod are connected in a left-right sliding manner, and the main cross-section of the calibration rod is a side "T" - shaped structure. And there are 3 groups of the calibration rods distributed at equal angles with respect to the longitudinal center line of the moving rod. This design can flexibly adjust the position of the calibration seat, thereby adjusting the position of the mounting bracket.

[0020] Preferably, the main cross-section of the mounting bracket is an inverted "T" - shaped structure, and the mounting bracket penetrates through the end of the robotic arm and is slidably connected to the end of the robotic arm.

[0021] Preferably, the first magnet and the second magnet are magnets with opposite poles, and the positions of the first magnet and the second magnet are arranged in one - to - one correspondence. This design enables the first magnet and the second magnet to attract each other, and uses the attractive force to control the movement of the moving rod.

[0022] Preferably, the fixing bracket is sleeved on the outside of the sliding rod and is slidably connected to the sliding rod. And the fixing bracket and the mounting bracket form an up - and - down sliding structure through the limiting block with a side "T" - shaped structure in the front - view cross - section. This design can ensure that the mounting bracket can move vertically smoothly while the height position of the fixing bracket remains unchanged.

[0023] Preferably, the main cross - section of the dust suction hood is inclined, and the lowest point of the dust suction hood is higher than the lowest point of the adjusting air pipe. This design can make the dust suction hood align with the polished edge of the optical lens and adsorb and clean the polishing debris.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] (1) For the robotic arm used in the preparation of the dust - suppressing and cleanable optical equipment, a baffle is provided to control the movement of the calibration seat. According to the size of the radius of the optical lens specification, the position of the calibration seat on the calibration rod is adjusted, thereby adjusting the position of the fixing bracket, so that the length of the side of the first magnet and the second magnet away from the adjusting air pipe to the vertical center line of the adjusting air pipe is the same as the radius of the optical lens. The baffle at the adjacent position corrects the optical lens. The optical lens moves at the circumferential position where the adjusting air pipe is located. When the optical lens completely blocks the first magnet and the second magnet, the central position of the optical lens coincides with the rotation center position of the adjusting air pipe, and at the same time, the attractive force between the magnets is released. The internal negative pressure of the strong suction cup is adjusted to achieve the rapid adsorption and locking of the optical lens. This design ensures that the fitting degree of each part of the optical lens with the polishing equipment is the same during rotation, and avoids defects caused by uneven polishing at the edge of the optical lens.

[0026] (2) The robotic arm for preparing optical equipment that can suppress dust and clean is provided with a dust suction hood. The dust suction hood is inclined and the head of the dust suction hood is inclined towards the grinding area of the optical lens. The cleaning pipeline composed of a vacuum cleaner, a dust suction pipe and the dust suction hood is used to absorb and clean the flying chips, realizing the function of suppressing dust and cleaning, and avoiding the accumulation of waste chips in the gaps of the robotic arm, which affects the service life of the robotic arm.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1-9 , the present invention provides the following technical solution: A robotic arm for preparing optical equipment that can suppress dust and clean

[0039] Embodiment 1:

[0040] The existing robotic arm for preparing optical equipment cannot be calibrated and locked according to the specification size of the optical lens 23, and cannot lock the central position of the optical lens 23 on the rotation axis. As a result, when the optical lens 23 rotates for edge grinding, the thickness of the edge grinding is different, resulting in defects in the prepared finished product of the optical lens 23. Therefore, to solve this technical problem, this embodiment further includes a robotic arm main body 1, and a robotic arm end 2 is installed at the upper left end of the robotic arm main body 1; an adjustment air pipe 3 runs through the inside of the robotic arm end 2, and a support ring 4 is installed on the outer side of the adjustment air pipe 3, and a toothed block 5 is connected to the outer side of the support ring 4; a piston 6 is slidably connected inside the adjustment air pipe 3, and a strong suction cup 22 is connected to the lower side of the adjustment air pipe 3, and a moving rod 7 is connected to the upper side of the piston 6. At the same time, the moving rod 7 is elastically connected to the adjustment air pipe 3 through a compression spring 8; an annular groove 9 is opened on the outer side of the moving rod 7, and a calibration rod 10 is slidably connected inside the annular groove 9, and a calibration seat 11 is sleeved on the outer side of the calibration rod 10. The calibration seat 11 and the calibration rod 10 are fixed by bolts, and a mounting bracket 12 is connected to the lower side of the calibration seat 11; a sliding rod 16 is connected to the outer side of the robotic arm end 2; a motor 19 is installed above the left of the robotic arm end 2, and the output end of the motor 19 is connected to a rotating rod 20, and the rotating rod 20 is rotatably connected to the robotic arm end 2. At the same time, a gear 21 is key-connected to the outer side of the rotating rod 20; an optical lens 23 is attached to the lower side of the strong suction cup 22;

[0041] The mounting bracket 12 is also provided with a first magnet 13 and a limit block 14: a first magnet 13 is connected to the lower side of the mounting bracket 12; a limit block 14 is slidably connected inside the mounting bracket 12, and a fixing bracket 15 is installed at the end of the limit block 14, and a second magnet 17 and a baffle 18 are installed at the bottom end of the fixing bracket 15.

[0042] The adjusting air pipe 3 and the end of the robotic arm 2 form a rotating structure through the support ring 4, and tooth blocks 5 are evenly distributed at the connection between the support ring 4 and the gear 21. The vertical centerlines of the moving rod 7 and the adjusting air pipe 3 coincide with each other, and the moving rod 7 is slidably connected to the calibration rod 10. The calibration seat 11 is slidably connected to the calibration rod 10 in the left-right direction, and the main cross-section of the calibration rod 10 is a side "T" shaped structure, and three groups of calibration rods 10 are evenly distributed around the longitudinal centerline of the moving rod 7. The main cross-section of the mounting bracket 12 is an inverted "T" shaped structure, and the mounting bracket 12 penetrates through the end of the robotic arm 2 and is slidably connected to the end of the robotic arm 2. The first magnet 13 and the second magnet 17 are magnets with opposite poles, and the positions of the first magnet 13 and the second magnet 17 are arranged in one-to-one correspondence. The fixing bracket 15 is sleeved outside the sliding rod 16 and is slidably connected to the sliding rod 16, and the fixing bracket 15 and the mounting bracket 12 form an up-and-down sliding structure through the limiting block 14 with a side "T" shaped structure in the front view cross-section.

[0043] The working principle of this embodiment: According to Figures 1-3As shown, the positions of the first magnet 13 and the second magnet 17 can be adjusted according to the size of the optical lens 23. The scale distance on the calibration rod 10 is the length between the vertical center line of the adjustment air pipe 3. The calibration seat 11 can be pushed to slide on the calibration rod 10. The calibration seat 11 controls the movement of the mounting bracket 12 installed on the lower side. The mounting bracket 12 drives the fixing bracket 15 to move. The fixing bracket 15 slides synchronously on the outside of the slide rod 16 to ensure the stable horizontal movement of the fixing bracket 15, so that the positions of the first magnet 13 and the second magnet 17 can be adjusted. The side of the calibration seat 11 away from the adjustment air pipe 3 and the side of the first magnet 13 and the second magnet 17 away from the adjustment air pipe 3 are located in the same vertical plane. Therefore, the scale distance of this side of the calibration seat 11 is the distance between the first magnet 1 3 and the second magnet 17 on the same side to adjust the length of the vertical center line of the trachea 3 to ensure that this length is the same as the radius of the optical lens 23, and use bolts to lock the calibration seat 11 and the calibration rod 10. According to the above steps, adjust the positions of the three groups of first magnets 13 and second magnets 17 with equal angles, and then use the above structure to calibrate the position of the optical lens 23. The upper side of the optical lens 23 is fitted with the strong suction cup 22 for movement, and the baffle 18 installed on the fixing frame 15 with equal angles is used to correct the optical lens 23 to prevent the optical lens 23 from deviating from the circumferential position of the adjusting trachea 3 until the optical lens 23 is blocked between the first magnet 13 and the second magnet 17. At this time, the vertical center position of the optical lens 23 is aligned with the circumferential position of the adjusting trachea 3. The vertical center positions coincide, and the mutual attraction between the first magnet 13 and the second magnet 17 with different polarities is released. At this time, the compression spring 8 in the compressed and stored state can control the moving rod 7 to move up and reset. At this time, the calibration seat 11 set on the outside of the moving rod 7 moves up synchronously, thereby controlling the mounting bracket 12 to move up. The mounting bracket 12 and the limit block 14 slide with each other, so that the moving rod 7 can move up smoothly without changing the position of the fixing bracket 15, thereby controlling the piston 6 to move up and reset. The piston 6 slides in the regulating air pipe 3, and the negative pressure is used to make the strong suction cup 22 tightly adsorb and fix the optical lens 23. The motor 19 is powered on, and the motor 19 controls the rotating rod 20 connected to the output end to rotate. The rotating rod 20 controls the gear 21 connected to the outer key to rotate. The gear 21 is meshed with the gear block 5, so it can control the rotation of the support ring 4, and the support ring 4 controls the rotation of the regulating air pipe 3 installed inside. Since the end of the calibration rod 10 can slide in the annular groove 9, the smooth rotation of the moving rod 7 can be achieved, thereby ensuring the smooth rotation of the regulating air pipe 3, and then the locked optical lens 23 can be controlled to rotate. The robot arm body 1 controls the robot arm end 2 to move the optical lens 23 to the grinding equipment, and grinds the edge of the optical lens 23. After the processing is completed, it is only necessary to press the moving rod 7 downward. The moving rod 7 presses and stores force on the compression spring 8, and controls the piston 6 installed at the lower end to move downward, and delivers the airflow to the strong suction cup 22, releasing the strong suction cup 22 from adsorbing and fixing the optical lens 23, and the optical lens 23 can fall off.The first magnet 13 and the second magnet 17 that are unblocked attract each other, and the attraction locks the mounting frame 12 and the moving rod 7 in the downward state, so that the new optical lens 23 can be calibrated and locked as described above.

[0044] Example 2:

[0045] The existing robotic arm for preparing optical equipment cannot perform dust suppression and cleaning during the polishing process of the optical lens 23, and the polishing debris floats and pollutes the surrounding environment. Therefore, in order to solve this technical problem, the present embodiment also includes a vacuum cleaner 24, which is installed on the lower right side of the robotic arm body 1, and the dust suction port of the vacuum cleaner 24 is connected to a dust suction pipe 25, and the other end of the dust suction pipe 25 is connected to a dust suction hood 26, and the dust suction hood 26 is installed on the lower left side of the robotic arm end 2.

[0046] The main cross-section of the dust hood 26 is distributed in an inclined shape, and the lowest point of the dust hood 26 is higher than the lowest point of the regulating air pipe 3.

[0047] The working principle of this embodiment is: when the calibrated and locked optical lens 23 is polished at the edge, debris will be generated and the vacuum cleaner 24 will be powered on to work. The vacuum cleaner 24 absorbs and cleans the debris through the vacuum tube 25 and the dust hood 26, which has the effect of dust suppression and cleaning.
