[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The workpiece is supported and fixed by the first movable plate, and then the workpiece is moved to the position of the tightening shaft by the first movable plate for assembly. After tightening and testing, the workpiece is moved again to the code engraving and scanning station for code engraving and scanning. The full process of tightening, coding and scanning is automated, and multiple processes are completed by a single machine, which reduces manual intervention and equipment switching time and improves production speed.

[0015] 2. When engraving, the scraper and brush rotate synchronously when the cleaning plate rotates, and then the cleaning plate scrapes and cleans the area around the laser engraving position, so that impurities adhering to the surface of the workpiece are separated. As the engraving position changes, the position of the cleaning plate changes. The subsequent brush can clean up the remaining powdery fine impurities after passing through the position scraped and cleaned by the scraper, so that the position on the workpiece surface where the code is about to be engraved is cleaned in advance, avoiding impurities blocking the engraving position and affecting the engraving quality, thereby improving the engraving quality.

[0016] 3. Due to the inclined surface setting on the cleaning plate, the inner side of the upper surface of the cleaning plate is lower. Impurities splashed around during code engraving will move to the top of the cleaning plate. With the rapid rotation of the cleaning plate and the existence of the push plate, the splashed impurities will pass over the cleaning plate from between the push plates, fall onto the cleaning plate, or contact the push plate during the splashing process. The impurities that fall on the cleaning plate will move outward along the cleaning inclined surface under the centrifugal force and the push plate and be thrown out. The impurities that contact the push plate during the splashing process will accelerate to fly outward after contacting the push plate, so that the splashed impurities can all be moved to the outside of the cleaning plate and can be cleaned by the scraper and brush later, further reducing the probability of the code engraving position being blocked by impurities and further improving the quality of code engraving.

[0017] 4. During the coding process, impurities flying around come into contact with the soft buffer net. After the impurities collide with the soft buffer net, the soft buffer net will deform, thereby unloading the force on the impurities, causing the impurities to fall downward after the collision, preventing the impurities from colliding with the inner wall of the protective tube and rebounding to the coding position again, further improving the cleanliness of the coding position. At the same time, the air blown downward by multiple groups of blow pipes forms an air curtain. When the impurities fly through the area where the air curtain is located, the air will exert a downward force on the impurities, and even blow the impurities downward, further reducing the kinetic energy of the impurities when they collide with the soft buffer net, further reducing the rebound distance of the impurities, and the diameter of the blow pipe gradually decreases to prevent the impurities from being blown downward by the air and colliding with the blow pipe below, ensuring that the impurities can fall smoothly to the edge of the protective tube, further improving the cleanliness of the coding position and improving the quality of the coding.

[0027] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0028] like Figure 1-Figure 7As shown, a high-definition code engraving machine with an automatic tightening structure provided by the present invention includes a base 1, a first movable plate 2 is slidably mounted on the base 1, and a first servo module 3 is provided on the base 1 to drive the first movable plate 2 to move, a supporting and fixing component 51 is provided on the first movable plate 2, a first bracket 17 is fixedly mounted on the base 1, a T-shaped second movable plate 18 is slidably mounted on the horizontal section of the first bracket 17, a second servo module 19 is provided on the first bracket 17 to drive the second movable plate 18 to move, a third movable plate 20 is slidably mounted on the vertical section of the second movable plate 18, and a third servo module 21 is provided on the vertical section of the second movable plate 18 to drive the third movable plate 20 to move, the second movable plate 18 is perpendicular to the moving direction of the third movable plate 20, and a third movable plate 20 is provided on the third movable plate 20 There are a tightening shaft 22 and a height measuring cylinder 23, a second bracket 24 is fixedly installed on the base 1, a fourth movable plate 25 is slidably installed on the horizontal section of the second bracket 24, and the horizontal section of the second bracket 24 is provided with a second adjusting threaded rod 26 that drives the fourth movable plate 25 to move, a second telescopic member 27 is fixedly installed on the fourth movable plate 25, the second telescopic member 27 points to the base 1 and a first rotating power member 28 is fixedly installed on its output end, a mounting plate 29 is fixedly installed on the end of the output shaft of the first rotating power member 28, a scanning device body 30 and a laser emitter 34 are provided on the surface of the mounting plate 29 close to the base 1, a fourth servo module 33 that drives the laser emitter 34 to move is provided on the mounting plate 29, and the moving trajectory of the first movable plate 2 passes through the first bracket 17 and the second bracket 24.

[0029] In actual application of this embodiment, the workpiece is placed on the first movable plate 2 and supported and fixed by the supporting and fixing component 51. At the same time, the supporting and fixing component 51 can position the workpiece and place the screw at the specified position. Then, the first servo module 3 drives the first movable plate 2 to move toward the direction close to the first bracket 17 to the bottom of the tightening shaft 22. Then, the second servo module 19 drives the second movable plate 18 to move horizontally. In conjunction with the movement of the first movable plate 2, the tightening shaft 22 can be moved to the top of the screw. Then, the third servo module 21 drives the third movable plate 20 moves downward to connect the tightening shaft 22 with the screw, and then the screw can be tightened by the tightening shaft 22. After the tightening is completed, the third movable plate 20 is reset, and then the tightening shaft 22 is moved to the top of another group of screws by the movement coordination of the second movable plate 18 and the first movable plate 2. Repeat the above operation to complete the tightening of all screws. After the tightening is completed, continue to repeat the above steps to move the height measuring cylinder 23 to the top of each group of screws, and then the height measuring cylinder 23 extends downward until it contacts the screw to complete the height measurement, and then detect whether the screw is tightened to the set position.

[0030] According to the position of the engraving, the fourth movable plate 25 is driven to move to the set position by the second adjusting threaded rod 26. After the screw tightening status detection is completed, the first movable plate 2 moves to the bottom of the second bracket 24, so that the position of the workpiece engraving code is moved to just below the laser emitter 34. The second telescopic member 27 drives the mounting plate 29 to drop to the set height. When engraving, the laser emitter 34 is driven to move horizontally by the fourth servo module 33, and the workpiece is driven to move along the direction perpendicular to the moving trajectory of the laser emitter 34 by the first movable plate 2. The laser emitter 34 emits a laser to the surface of the workpiece for engraving. After the engraving is completed, the first rotating power member 28 drives the mounting plate 29 to rotate one hundred and eighty degrees so that the code scanning device body 30 rotates to the top of the engraving code. Then, the code scanning device body 30 scans the engraving code. After the code is qualified, the first movable plate 2 drives the workpiece to move to the dot marking position for dot marking. After the dot marking is completed, the first movable plate 2 is reset and the workpiece is unloaded and replaced with a new workpiece, realizing the automation of the entire process of tightening, engraving and scanning. A single machine completes multiple processes, reducing manual intervention and equipment switching time, and improving production speed.

[0031] In an example of this embodiment, the first rotating power component 28 is a first motor, and of course it can also be other components that can output rotational power, such as a hydraulic motor. The first motor drives the mounting plate 29 to rotate, and the second telescopic component 27 is a second electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder, and the mounting plate 29 is driven up and down by the second electric telescopic rod.

[0032] like Figure 1-Figure 3 As shown, a high-definition code engraving machine with an automatic tightening structure provided by the present invention, the supporting and fixing assembly 51 includes a pad 4, two groups of pads 4 are provided and fixedly installed on the first movable plate 2, a support plate 5 is fixedly installed on the side of the pad 4, a vertical plate 6 is slidably installed on the support plate 5, a pressure plate 7 is rotatably installed on the end of the vertical plate 6 away from the first movable plate 2, and a first telescopic part 8 is provided on the vertical plate 6 to drive the pressure plate 7 to rotate, a first adjusting threaded rod 9 that drives the vertical plate 6 to move up and down is threadedly installed on the support plate 5, and a positioning pin 11 is provided on the first movable plate 2.

[0033] Specifically, two groups of mounting seats 10 are provided on the first movable plate 2, one group of mounting seats 10 is fixedly connected to the first movable plate 2, the positioning pin 11 is threadedly installed on the mounting seat 10, and a mounting ring 12 is rotatably installed on the mounting seat 10. The two groups of mounting rings 12 are connected by a telescopic rod 13, and a fixing screw 14 is threadedly installed on one end of the telescopic rod 13 close to the movable mounting seat 10.

[0034] Specifically, a plurality of support seats 15 are provided on the first movable plate 2 , and pads 16 are threadedly mounted on the support seats 15 . The first movable plate 2 is provided with a plurality of positioning holes for inserting the support seats 15 .

[0035] In actual application of this embodiment, according to the size of the positioning holes on the workpiece, the positioning pins 11 of the corresponding size 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 achieve the fixation of 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 applied to the positioning of different workpieces, thereby improving the practicality of the equipment. After the positioning pin 11 is positioned, it is placed on the pad 4 for support. According to the height of the workpiece, the vertical plate 6 is driven 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 pad 4. According to the height 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, further improving the stability of the support.

[0036] 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 pressure plate 7 to rotate, thereby achieving the tightening and release of the workpiece.

[0037] like Figure 4-Figure 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.

[0038] 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. A plurality of connecting rods 39 are fixedly mounted on the rotating ring 37, and a ring-shaped cleaning plate 40 is fixedly mounted on one end of the connecting rods 39 away from the rotating ring 37. The cleaning plate 40 is coaxially arranged with the rotating ring 37, and the laser engraving position is located inside the cleaning plate 40. A second rotating power component 35 is fixedly mounted on the substrate 32, and a gear 36 is fixedly mounted on the output end of the second rotating power component 35. The gear 36 is engaged 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.

[0039] There is a gap between the cleaning plate 40 and the lower surface of the protective tube 31. The surface of the cleaning plate 40 away from the base 1 is set as a slope structure with a lower inner side and a higher outer side, and a plurality of push plates 43 are fixedly installed thereon. The surface of the cleaning plate 40 close to the base 1 is fixedly installed with a plurality of scrapers 41 distributed at intervals, and the lower surface of the scraper 41 is flush with the lower surface of the protective tube 31. The surface of the cleaning plate 40 close to the base 1 is fixedly installed with a plurality of evenly distributed brushes 42, which are located on the inner side of the distribution area of ​​the scraper 41, and the cleaning surface of the brush 42 is flush with the lower surface of the protective tube 31.

[0040] In actual application of this embodiment, when engraving, 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 bottom of the scraper 41 and the brush 42 are in contact with the upper surface of the workpiece without pressure. When engraving, the fourth servo module 33 drives the base plate 32 to move back and forth, and at the same time drives the workpiece to move through the first movable plate 2, so that the laser emitted by the laser emitter 34 can perform coding operations on the surface of the workpiece. At the same time, the second rotating power member 35 drives the rotating ring 37 to rotate rapidly through the meshing gear 36 and the ring gear 38, and the rotating ring 37 drives the cleaning plate 40 to rotate synchronously. When the cleaning plate 40 rotates, the scraper 41 and the brush 42 rotate synchronously, and then the cleaning plate 40 scrapes and cleans the area around the laser engraving position, so that impurities adhered to the surface of the workpiece are detached. As the engraving position changes, the position of the cleaning plate 40 changes, and the subsequent brush 42 can remove the remaining powdery fine particles after passing through the position scraped and cleaned by the scraper 41. The impurities are cleaned up, so that the position on the workpiece surface where the code is to be engraved is cleaned in advance, and impurities are prevented from blocking the engraving position and affecting the engraving quality, thereby improving the engraving 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, and impurities splashed around during engraving will move to the top of the cleaning plate 40. With the rapid rotation of the cleaning plate 40 and the existence of the push plate 43, the splashed impurities will pass through the cleaning plate 40 between the push plates 43 and fall on the cleaning plate 40, or contact the push plate 43 during the splashing process. The impurities that fall on the cleaning plate 40 will move outward along the inclined surface of the cleaning plate 40 under the push of centrifugal force and the push plate 43 and be thrown out. The impurities that contact the push plate 43 during the splashing process will accelerate to fly outward after contacting the push plate 43, so that the splashed impurities can all be moved to the outside of the cleaning plate 40, and can be cleaned by the scraper 41 and the brush 42 later, further reducing the probability of the engraving position being blocked by impurities, and further improving the engraving quality.

[0041] In one embodiment of the present invention, the second rotating power component 35 is a second motor, and of course it can also be other components capable of outputting rotating power, such as a hydraulic motor, and the cleaning plate 40 is driven to rotate by the second motor.

[0042] like Figure 4-Figure 7As shown, a high-definition code engraving machine with an automatic tightening structure provided by the present invention, a ring-shaped top plate 44 is fixedly installed in the protective tube 31, the top plate 44 is coaxially arranged with the protective tube 31, and 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 tube 31 and a gap is set between the soft buffer net 45 and the inner wall of the protective tube 31.

[0043] Specifically, multiple groups of blowing pipes 47 at different heights are fixedly installed on the top plate 44. The blowing pipes 47 are annular and coaxially arranged with the protective tube 31. The diameter of the blowing pipes 47 gradually decreases towards the base 1. The surface of the blowing pipes 47 close to the base 1 is provided with multiple groups of spaced blowing holes 48. A connecting chamber 46 is fixedly installed on the top plate 44. The connecting chamber 46 is connected to the multiple groups of blowing pipes 47. A hair dryer 49 connected to the connecting chamber 46 is fixedly installed on the outside of the protective tube 31. An exhaust fan 50 is fixedly installed on the outside of the protective tube 31. The air inlet end of the exhaust fan 50 is connected to the protective tube 31 and is located at the end of the protective tube 31 away from the mounting plate 29.

[0044] In actual application of this embodiment, impurities splashed around during the code engraving process come into contact with the soft buffer net 45. After the impurities collide with the soft buffer net 45, the soft buffer net 45 will be deformed, thereby unloading the force on the impurities, causing the impurities to fall downward after the collision, avoiding the impurities from colliding with the inner wall of the protective tube 31 and rebounding to the position of the code engraving again, further improving the cleanliness of the code engraving position. While engraving, air is transported into the connecting chamber 46 through the blower 49, and the air in the connecting chamber 46 is transported to the multiple groups of blowing pipes 47 and blown downward through the blowing holes 48, so that the air blown downward through the multiple groups of blowing pipes 47 forms a wind curtain. When the impurities pass through the area where the wind curtain is located during the process of splashing, the air will The air blower 47 exerts a downward force on the impurities, and even blows the impurities downward, further reducing the kinetic energy of the impurities when colliding with the soft buffer net 45, further reducing the rebound distance of the impurities, and the diameter of the blowing pipe 47 is gradually reduced to prevent the air from blowing the impurities downward and colliding with the blowing pipe 47 below, ensuring that the impurities can fall smoothly to the edge of the protective tube 31, further improving the cleanliness of the engraving position, and improving the quality of the engraving. At the same time, the exhaust fan 50 draws the air from the lower part of the protective tube 31, so that the air in the protective tube 31 flows downward, avoiding the smoke generated during the engraving process from flowing upward and contacting the laser emitter 34, avoiding affecting the laser emitter 34, and further improving the quality of the engraving.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
