Product identification engraving and screw fastening are mostly carried out in separate steps, with low efficiency and poor consistency. Therefore, a high-definition code engraving and automatic tightening all-in-one machine is needed to improve production efficiency. Summary of the Invention

[0005] Preferably, the support and fixation component includes two sets of pads, which are fixedly mounted on the first moving plate. A support plate is fixedly mounted on the side surface of the pad. A vertical plate is slidably mounted on the support plate. A pressing plate is rotatably mounted at one end of the vertical plate away from the first moving plate, and a first telescopic member for driving the pressing plate to rotate is provided on the vertical plate.

[0006] Preferably, two sets of mounting seats are arranged on the first moving plate. One set of mounting seats is fixedly connected to the first moving plate. The positioning pins are threadedly mounted on the mounting seats. An installation ring is rotatably mounted on the mounting seats. The two installation rings are connected by a telescopic rod. A fixing screw is threadedly mounted at one end of the telescopic rod close to the movable mounting seat.

[0007] Preferably, multiple sets of supporting seats are arranged on the first moving plate. A backing plate is threadedly mounted on the supporting seats. Multiple sets of positioning holes for inserting the supporting seats are formed on the first moving plate.

[0008] Preferably, a protective cylinder is fixedly mounted on the mounting plate. A substrate is slidably mounted in the protective cylinder and the fourth servo module drives the substrate to move. A laser emitter is fixedly mounted on the substrate.

[0009] Preferably, a rotating ring distributed around the laser emitter is rotatably mounted on the surface of the substrate close to the base. Multiple sets of connecting rods are fixedly mounted on the rotating ring and the ends of the connecting rods far from the rotating ring are commonly fixedly mounted with an annular cleaning plate. The cleaning plate is coaxially arranged with the rotating ring and the laser engraving position is located inside the cleaning plate. A second rotating power member is fixedly mounted on the substrate. A gear is fixedly mounted at the output end of the second rotating power member. The gear meshes with a toothed ring fixedly mounted on the rotating ring. The toothed ring is coaxially arranged with the rotating ring.

[0010] Preferably, there is a gap between the cleaning plate and the lower surface of the protective cylinder. The surface of the cleaning plate far from the base is set as an inclined surface structure with a lower inner side and a higher outer side and multiple sets of push plates are fixedly mounted thereon at intervals. Multiple sets of scraping plates are fixedly mounted on the surface of the cleaning plate close to the base at intervals. The lower surface of the scraping plate is flush with the lower surface of the protective cylinder. Multiple sets of uniformly distributed brushes are fixedly mounted on the surface of the cleaning plate close to the base. The brushes are located inside the distribution area of the scraping plates. The cleaning surface of the brushes is flush with the lower surface of the protective cylinder.

[0011] Preferably, an annular top plate is fixedly mounted in the protective cylinder. The top plate is coaxially arranged with the protective cylinder. A cylindrical soft buffer net is fixedly mounted on the top plate. The soft buffer net is coaxially arranged with the protective cylinder and there is a gap between the soft buffer net and the inner wall of the protective cylinder.

[0012] Preferably, multiple sets of air blowing pipes at different heights are fixedly mounted on the top plate. The air blowing pipes are annular and coaxially arranged with the protective cylinder. The diameter of the air blowing pipes gradually decreases towards the direction close to the base. Multiple sets of air blowing holes are formed on the surface of the air blowing pipes close to the base at intervals. A communication chamber is fixedly mounted on the top plate. The communication chamber is communicated with multiple sets of air blowing pipes. A blower is fixedly mounted outside the protective cylinder and is communicated with the communication chamber. An exhaust fan is fixedly mounted outside the protective cylinder. The air inlet end of the exhaust fan is communicated with the protective cylinder and is located at one end of the protective cylinder far from the mounting plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The workpiece is supported and fixed by the first moving plate. Then, the first moving plate drives the workpiece to move to the position where the tightening shaft is located for assembly. After tightening and inspection are completed, the workpiece is moved to the coding and scanning station again for coding and scanning. This realizes the full-process automation of tightening, coding, and scanning, completes multiple processes with a single machine, reduces manual intervention and equipment switching time, and improves production speed.

[0014] 2. During coding, when the cleaning plate rotates, the scraping plate and the brush rotate synchronously. Thus, the cleaning plate scrapes and cleans the surrounding area of the laser coding position, causing the impurities adhered to the surface of the workpiece to separate. As the coding position changes, the position of the cleaning plate changes. Subsequently, after the brush passes through the position scraped and cleaned by the scraping plate, it can clean the remaining powdery and fine impurities, making the position on the workpiece surface where coding is about to be performed cleaned in advance, avoiding impurities blocking the coding position and affecting the coding quality, and improving the coding quality.

[0015] 3. Due to the inclined surface setting on the cleaning plate, the inner side of the upper surface of the cleaning plate is lower. During coding, the impurities splashing around will move above the cleaning plate. With the rapid rotation of the cleaning plate and the presence of the pushing plate, the splashing impurities will cross over the cleaning plate between the pushing plates, fall onto the cleaning plate, or contact the pushing plate during the splashing process. The impurities falling onto the cleaning plate will move outward along the inclined surface of the cleaning under the action of centrifugal force and the pushing of the pushing plate and be thrown out. The impurities contacting the pushing plate during the splashing process will accelerate and fly outward after contacting the pushing plate, enabling the splashing impurities to all move to the outside of the cleaning plate and be subsequently cleaned by the scraping plate and the brush, further reducing the probability of the coding position being blocked by impurities and further improving the coding quality.

[0016] 4. During the coding process, the impurities splashing around contact the soft buffer net. After the impurities impact the soft buffer net, the soft buffer net will deform, thereby unloading the force on the impurities, causing the impurities to fall downward after impact, avoiding the impurities hitting the inner wall of the protective cylinder and rebounding back to the coding position, further improving the cleanliness of the coding position. At the same time, the air blown downward by multiple air pipes forms an air curtain. When the impurities pass through the area where the air curtain is located during the splashing process, the air will exert a downward force on the impurities, even blowing the impurities downward, further reducing the kinetic energy of the impurities when they impact the soft buffer net, further reducing the rebound distance of the impurities, and the diameter of the air pipe gradually decreases to avoid the air blowing the impurities downward and hitting the lower air pipe, ensuring that the impurities can smoothly fall to the edge position of the protective cylinder, further improving the cleanliness of the coding position and the coding quality.

Detailed implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0027] As Figures 1-7As shown in the figure, a high-definition code engraving machine with an automatic tightening structure provided by the present invention includes a base 1. A first moving plate 2 is slidably mounted on the base 1, and a first servo module 3 for driving the first moving plate 2 to move is provided on the base 1. A support and fixing component 51 is provided on the first moving plate 2. A first bracket 17 is fixedly mounted on the base 1. A T-shaped second moving plate 18 is slidably mounted on the horizontal section of the first bracket 17, and a second servo module 19 for driving the second moving plate 18 to move is provided on the first bracket 17. A third moving plate 20 is slidably mounted on the vertical section of the second moving plate 18, and a third servo module 21 for driving the third moving plate 20 to move is provided on the vertical section of the second moving plate 18. The moving directions of the second moving plate 18 and the third moving plate 20 are perpendicular to each other. A tightening shaft 22 and a height measuring cylinder 23 are provided on the third moving plate 20. A second bracket 24 is fixedly mounted on the base 1. A fourth moving plate 25 is slidably mounted on the horizontal section of the second bracket 24, and a second adjusting screw rod 26 for driving the fourth moving plate 25 to move is provided on the horizontal section of the second bracket 24. A second telescopic member 27 is fixedly mounted on the fourth moving plate 25. The second telescopic member 27 points to the base 1, and a first rotating power member 28 is fixedly mounted at its output end. An installation plate 29 is fixedly mounted at the end of the output shaft of the first rotating power member 28. A code scanning device main body 30 and a laser emitter 34 are provided on the surface of the installation plate 29 close to the base 1. A fourth servo module 33 for driving the laser emitter 34 to move is provided on the installation plate 29. The moving track of the first moving plate 2 passes through the first bracket 17 and the second bracket 24.

[0028] In actual application of this embodiment, the workpiece is placed on the first moving plate 2, and the support and fixing component 51 supports and fixes the workpiece. At the same time, the support and fixing component 51 can position the workpiece. The screw is placed at the designated position. Then, the first servo module 3 drives the first moving plate 2 to move towards the direction close to the first bracket 17 until it is below the tightening shaft 22. Then, the second servo module 19 drives the second moving plate 18 to move horizontally. Combining with the movement of the first moving plate 2, the tightening shaft 22 can be moved directly above the screw. Then, the third servo module 21 drives the third moving plate 20 to move downward so that the tightening shaft 22 is connected to the screw. Then, the screw can be tightened by the tightening shaft 22. After tightening is completed, the third moving plate 20 returns to its original position. Then, again through the movement cooperation of the second moving plate 18 and the first moving plate 2, the tightening shaft 22 is moved directly above another group of screws, and the above operations are repeated to complete the tightening operation of all screws. After tightening is completed, continue to repeat the above steps to move the height measuring cylinder 23 above each group of screws. Then, the height measuring cylinder 23 extends downward until it contacts the screw to complete height measurement, thereby detecting whether the screw is tightened to the set position.

[0029] Drive the fourth moving plate 25 to move to the set position through the second adjusting screw rod 26 according to the position of the code engraving. After the detection of the tightened state of the screw is completed, the first moving plate 2 moves downward below the second bracket 24 to move the position of the workpiece code engraving directly below the laser emitter 34. Drive the mounting plate 29 to descend to the set height through the second telescopic member 27. During code engraving, drive the laser emitter 34 to move horizontally through the fourth servo module 33, and drive the workpiece to move along the direction perpendicular to the moving track of the laser emitter 34 through the first moving plate 2. The laser emitter 34 emits laser light onto the surface of the workpiece for code engraving. After the code engraving is completed, the first rotating power member 28 drives the mounting plate 29 to rotate 180 degrees to make the code scanning device main body 30 rotate above the code engraving. Then, scan the code through the code scanning device main body 30. After the code scanning is qualified, the first moving plate 2 drives the workpiece to move to the punching position for punching. After the punching is completed, the first moving plate 2 resets and then unloads the workpiece to replace it with a new workpiece, realizing the full-process automation of tightening, code engraving, and code scanning, completing multiple processes with a single machine, reducing manual intervention and equipment switching time, and improving production speed.

[0030] In an example of this embodiment, the first rotating power member 28 is a first motor. Of course, it can also be other components such as a hydraulic motor that can output rotational power. Drive the mounting plate 29 to rotate through the first motor. The second telescopic member 27 is a second electric telescopic rod. Of course, it can also be other components such as a hydraulic cylinder that can actively change its length. Drive the mounting plate 29 to move up and down through the second electric telescopic rod.

[0031] As Figures 1-3 shown, a high-definition code engraving machine with an automatic tightening structure provided by the present invention, the support and fixing assembly 51 includes a cushion block 4. There are two groups of cushion blocks 4 and they are fixedly installed on the first moving plate 2. A support plate 5 is fixedly installed on the side of the cushion block 4. A vertical plate 6 is slidably installed on the support plate 5. A pressing plate 7 is rotatably installed at one end of the vertical plate 6 away from the first moving plate 2, and a first telescopic member 8 for driving the pressing plate 7 to rotate is arranged on the vertical plate 6. A first adjusting screw rod 9 for driving the vertical plate 6 to move up and down is threadedly installed on the support plate 5. A positioning pin 11 is arranged on the first moving plate 2.

[0032] Specifically, two groups of mounting seats 10 are arranged on the first moving plate 2. One group of mounting seats 10 is fixedly connected to the first moving plate 2. The positioning pin 11 is threadedly installed on the mounting seat 10. An installation ring 12 is rotatably installed on the mounting seat 10. The two installation rings 12 are connected through a telescopic rod 13. A fixing screw 14 is threadedly installed at one end of the telescopic rod 13 close to the movable mounting seat 10.

[0033] Specifically, multiple groups of support seats 15 are arranged on the first moving plate 2. A backing plate 16 is threadedly installed on the support seat 15. Multiple groups of positioning holes for the support seats 15 to be inserted are opened on the first moving plate 2.

[0034] In actual application of this embodiment, according to the size of the positioning holes on the workpiece, the positioning pins 11 of corresponding sizes are installed on the mounting seat 10 through threads, and then the positions of a group of movable mounting seats 10 are adjusted according to the positions of the positioning holes on the workpiece so that the positioning pins 11 on them correspond to the other group of positioning holes on the workpiece, and then the fixing screws 14 are rotated to move downward to contact the first movable plate 2 to fix the movable mounting seat 10. The workpiece is positioned by a group of fixed positioning pins 11 and a group of movable positioning pins 11, which can be suitable for positioning different workpieces, thereby improving the practicality of the equipment. After the positioning pin 11 is positioned, it is placed on the cushion block 4 for support. According to the height of the workpiece, the vertical plate 6 is driven to move up and down by the first adjusting threaded rod 9, so that the pressure plate 7 is at a suitable height. Thereafter, the pressure plate 7 is driven to rotate by the first telescopic member 8. After the pressure plate 7 contacts the workpiece, the workpiece is pressed against the cushion block 4. According to the heights of the different lower surfaces of the workpiece, multiple groups of support seats 15 are installed at corresponding positions on the first movable plate 2, and the rotation pad 16 is moved to the set height. After the subsequent workpiece is placed, the support seat 15 and the pad 16 can support the workpiece at different positions, thereby further improving the stability of the support.

[0035] In one embodiment of the present invention, the first telescopic member 8 is a first electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder. The first electric telescopic rod drives the pressing plate 7 to rotate, thereby achieving the clamping and release of the workpiece.

[0036] like Figures 4-7 As shown, a high-definition code engraving machine with an automatic tightening structure provided by the present invention, a protective tube 31 is fixedly installed on the mounting plate 29, a base plate 32 is slidably installed in the protective tube 31, and the fourth servo module 33 drives the base plate 32 to move, and a laser emitter 34 is fixedly installed on the base plate 32.

[0037] A rotating ring 37 distributed around the laser emitter 34 is rotatably mounted on the surface of the substrate 32 close to the base 1, and a plurality of sets of connecting rods 39 are fixedly mounted on the rotating ring 37, and an annular cleaning plate 40 is fixedly mounted on one end of the connecting rods 39 away from the rotating ring 37, and the cleaning plate 40 is coaxially arranged with the rotating ring 37, and the laser engraving position is located inside the cleaning plate 40, and a second rotating power member 35 is fixedly mounted on the substrate 32, and a gear 36 is fixedly mounted on the output end of the second rotating power member 35, and the gear 36 is meshed with a ring gear 38 fixedly mounted on the rotating ring 37, and the ring gear 38 is coaxially arranged with the rotating ring 37.

[0038] There is a gap between the cleaning plate 40 and the lower surface of the protective cylinder 31. The surface of the cleaning plate 40 away from the base 1 is set as an inclined surface structure with a lower inner side and a higher outer side, and multiple groups of evenly distributed push plates 43 are fixedly installed thereon. Multiple groups of evenly distributed scraping plates 41 are fixedly installed on the surface of the cleaning plate 40 close to the base 1. The lower surface of the scraping plate 41 is flush with the lower surface of the protective cylinder 31. Multiple groups of evenly distributed brushes 42 are fixedly installed on the surface of the cleaning plate 40 close to the base 1. The brushes 42 are located inside the distribution area of the scraping plates 41, and the cleaning surface of the brushes 42 is flush with the lower surface of the protective cylinder 31.

[0039] In actual application of this embodiment, when coding, the second telescopic member 27 drives the mounting plate 29 to move downward so that the lower surface of the protective cylinder 31 contacts the upper surface of the workpiece without pressure. At this time, the bottoms of the scraping plates 41 and the brushes 42 both contact the upper surface of the workpiece without pressure. When coding, the fourth servo module 33 drives the substrate 32 to reciprocate, and at the same time drives the workpiece to move through the first moving plate 2. Then, the laser emitted by the laser emitter 34 can perform coding operations on the surface of the workpiece. At the same time, the second rotary power member 35 drives the rotating ring 37 to rotate rapidly through the meshing gears 36 and the toothed ring 38. The rotating ring 37 drives the cleaning plate 40 to rotate synchronously. When the cleaning plate 40 rotates, the scraping plates 41 and the brushes 42 rotate synchronously. Then, the cleaning plate 40 scrapes and cleans the periphery of the laser coding position, so that the impurities adhered to the surface of the workpiece are separated. As the coding position changes, the position of the cleaning plate 40 changes. After the brushes 42 pass through the position scraped and cleaned by the scraping plates 41, they can clean the remaining powdery and fine impurities, so that the position on the surface of the workpiece to be coded is cleaned in advance, avoiding the influence of impurities blocking the coding position on the coding quality and improving the coding quality. Due to the inclined surface setting on the cleaning plate 40, the inner side of the upper surface of the cleaning plate 40 is lower. When coding, the impurities splashing around will move above the cleaning plate 40. With the rapid rotation of the cleaning plate 40 and the presence of the push plates 43, the splashing impurities will cross over the cleaning plate 40 between the push plates 43, fall onto the cleaning plate 40 or contact the push plates 43 during the splashing process. The impurities falling onto the cleaning plate 40 will move outward along the inclined surface of the cleaning plate 40 under the action of centrifugal force and the pushing of the push plates 43 and will be thrown out. The impurities contacting the push plates 43 during the splashing process will accelerate and fly outwards after contacting the push plates 43, so that all the splashing impurities can move to the outside of the cleaning plate 40 and can be cleaned by the scraping plates 41 and the brushes 42 later, further reducing the probability of the coding position being blocked by impurities and further improving the coding quality.

[0040] In an example of the present invention, the second rotary power member 35 is a second motor. Of course, it can also be other components such as a hydraulic motor that can output rotary power, and the cleaning plate 40 is driven to rotate by the second motor.

[0041] As Figures 4-7As shown in the figure, a high-definition code engraving machine with an automatic tightening structure provided by the present invention is equipped with an annular top plate 44 fixedly installed inside the protective cylinder 31. The top plate 44 is coaxially arranged with the protective cylinder 31. A cylindrical soft buffer net 45 is fixedly installed on the top plate 44. The soft buffer net 45 is coaxially arranged with the protective cylinder 31 and there is a gap between the soft buffer net 45 and the inner wall of the protective cylinder 31.

[0042] Specifically, multiple groups of air blowing pipes 47 at different heights are fixedly installed on the top plate 44. The air blowing pipes 47 are annular and coaxially arranged with the protective cylinder 31. The diameter of the air blowing pipes 47 gradually decreases towards the direction close to the base 1. Multiple groups of spaced air blowing holes 48 are formed on the surface of the air blowing pipes 47 close to the base 1. A communication chamber 46 is fixedly installed on the top plate 44. The communication chamber 46 is connected to multiple groups of air blowing pipes 47. A blower 49 connected to the communication chamber 46 is fixedly installed outside the protective cylinder 31. A suction fan 50 is fixedly installed outside the protective cylinder 31. The air inlet end of the suction fan 50 is connected to the protective cylinder 31 and is located at one end of the protective cylinder 31 away from the mounting plate 29.

[0043] In actual application of this embodiment, during the code engraving process, the impurities splashing around come into contact with the soft buffer net 45. After the impurities impact the soft buffer net 45, the soft buffer net 45 will deform, thereby unloading the force on the impurities, causing the impurities to fall downward after impact, avoiding the impurities from hitting the inner wall of the protective cylinder 31 and rebounding back to the code engraving position, further improving the cleanliness of the code engraving position. While engraving the code, air is conveyed into the communication chamber 46 by the blower 49. The air in the communication chamber 46 is conveyed into multiple groups of air blowing pipes 47 and blown downward through the air blowing holes 48. Thus, an air curtain is formed by the air blown downward through multiple groups of air blowing pipes 47. When the impurities pass through the area where the air curtain is located during the splashing process, the air will exert a downward force on the impurities, even blowing the impurities to move downward, further reducing the kinetic energy when the impurities impact the soft buffer net 45, further reducing the rebound distance of the impurities. Moreover, the diameter of the air blowing pipes 47 gradually shrinks to prevent the air from blowing the impurities downward and hitting the lower air blowing pipes 47, ensuring that the impurities can smoothly fall to the edge position of the protective cylinder 31, further improving the cleanliness of the code engraving position and the quality of code engraving. At the same time, the suction fan 50 extracts the air at the lower part inside the protective cylinder 31, causing the air inside the protective cylinder 31 to flow downward, avoiding the smoke generated during the code engraving process from flowing upward and contacting the laser emitter 34, and avoiding affecting the laser emitter 34, further improving the quality of code engraving.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.

[0045] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
