Description

Technical Field

[0001] The present invention relates to the technical field of hot processing, and particularly relates to a laser marking machine with an automatic feeding mechanism. Background Art

[0002] A laser marking machine uses a laser beam to permanently mark various different material surfaces. The marking effect is achieved by evaporating the surface layer material to expose the deeper layer material, thereby engraving exquisite patterns, trademarks, and characters. Traditional laser marking machines mainly include a laser generator, a control system, a workbench, etc. The overall structure is simple and the manufacturing cost is relatively low;

[0003] In the actual processing process, traditional laser marking machines do not have a feeding mechanism and need to be fed manually. This is time-consuming and laborious. At the same time, before laser marking, it is also necessary to manually calibrate the position of the workpiece to be processed, which is very troublesome. Moreover, before processing, it is necessary to always ensure the cleanliness of the surface of the workpiece to be processed, so as to maintain the subsequent marking quality. Finally, during the processing process, the monitoring of the workpiece to be processed is mainly completed by a camera. The workpiece to be processed is in a stationary state as a whole, and there are some shooting blind spots, so the actual situation of the workpiece to be processed cannot be perfectly captured, and manual care is required at all times. Therefore, a laser marking machine with an automatic feeding mechanism is provided. Summary of the Invention

[0034] First, when a marking operation needs to be performed, the workpiece to be processed is placed under the laser generator. A control system for controlling the operation of the laser generator is installed in the display screen. The control system is started through the display screen, and then the laser generator is started to start the marking operation.

[0036] When a marking operation is required, place the object to be processed on the conveyor belt, start the conveyor motor, and the conveyor motor drives the conveyor rod to rotate, thereby driving the conveyor belt and the object placed on the upper side of the conveyor belt to move until the object moves to the lower side of the laser generator, and then start the corresponding laser marking operation. This technology is also an existing and publicly disclosed technology, so it will not be elaborated here;

[0037] A feeding component is installed on the upper side of the body 1. The feeding component includes two threaded rods 7 rotatably installed on the upper side of the body 1. A feeding plate 3 is commonly threadedly connected to the outer sides of the two threaded rods 7. The outer sides of the two threaded rods 7 are both slidably connected with first gears 9. The first gears 9 are rotatably installed on the lower side of the feeding plate 3. Four inclined grooves 8 are symmetrically formed on the upper side of the feeding plate 3. Four first racks 13 and second racks 34 are slidably connected in the feeding plate 3. The positions and quantities of the four first racks 13 and the four second racks 34 correspond to the inclined grooves 8. Four rotating shafts 10 are rotatably penetrated and connected in the feeding plate 3. A second gear 11 is fixedly connected to the upper side of each rotating shaft 10. Both the first rack 13 and the second rack 34 are meshed with the second gear 11. A third gear 12 is fixedly connected to the lower side of each rotating shaft 10. The third gear 12 is meshed with the first gear 9. A sliding groove 29 is formed on the upper side of each first rack 13. A slider 28 is slidably connected in each sliding groove 29. A first spring 30 is fixedly connected between the slider 28 and the sliding groove 29. The outer side of the slider 28 is rotatably connected with a transmission rod 24. The outer side of the transmission rod 24 is slidably connected with a moving cylinder 25. Two first stop rods 32 are fixedly connected to the outer side of the moving cylinder 25. A stepped plate 16 is slidably connected in each inclined groove 8. The stepped plate 16 is fixedly connected to the second rack 34 through a right-angle rod. The outer side of the transmission rod 24 is rotatably connected with a rotating cylinder 14. The outer side of the transmission rod 24 is connected with a friction plate 15 through a sliding component. A plurality of rubber protrusions are fixedly connected to the outer side of the rotating cylinder 14; providing the friction force of the rotating cylinder 14 can better form the control operation of the object to be processed. The sliding component includes a top plate 17 fixedly installed on the upper side of the transmission rod 24. A first torsion spring 19 is fixedly connected between the top plate 17 and the rotating cylinder 14. A connecting plate 18 is fixedly connected to the side wall of the top plate 17. A plurality of moving rods 20 are slidably connected to the side wall of the connecting plate 18. Each moving rod 20 is fixedly connected to the friction plate 15, and a moving plate 22 is fixedly connected to the outer side of each moving rod 20. A second spring 21 is fixedly connected between the moving plate 22 and the connecting plate 18;

[0038] First, in the initial state, the loading plate 3 abuts against the conveyor belt, and the installation operation of the conveyor belt is formed. When the conveyor belt transports the workpiece to be processed, the workpiece to be processed will move to the upper side of the loading plate 3 under the action of the conveyor belt. Then, when the threaded rod 7 rotates, the loading plate 3 will move upward, shortening the distance between the workpiece to be processed and the laser emitter until the workpiece to be processed moves to a suitable processing position. During this process, the first gear 9 that moves with the loading plate 3 will also rotate under the action of the threaded rod 7. The first gear 9 drives the third gear 12 to rotate, and the third gear 12 drives the second gear 11 to rotate through the rotating shaft 10. The second gear 11 drives the first rack 13 to move towards the loading plate 3. The first rack 13 drives the transmission rod 24 to move through the first spring 30 and the slider 28, and the transmission rod 24 drives the outer rotating cylinder 14 to move. When one or several rotating cylinders 14 abut against the workpiece to be processed, under the extrusion action of the rotating cylinder 14, the workpiece to be processed will move towards the center point of the loading plate 3 until all the rotating cylinders 14 abut against the workpiece to be processed, thus completing the adjustment and fixation operation of the position of the workpiece to be processed;

[0039] During this process, the second gear 11 will also drive the second rack 34 to move away from the loading plate 3. The second rack 34 drives the stepped plate 16 to move through the right-angle rod. During the process of the transmission rod 24 following the first rack 13 to move, the transmission rod 24 drives the moving cylinder 25 to move, and the moving cylinder 25 drives the outer first stop rod 32 to move. When the first stop rod 32 abuts against the stepped plate 16, under the blocking action of the stepped plate 16, the moving cylinder 25 will rotate, the moving cylinder 25 drives the transmission rod 24 to rotate, the transmission rod 24 drives the friction plate 15 to rotate, and the friction plate 15 will abut against the workpiece to be processed placed on the upper side of the loading plate 3 to form friction cleaning of the workpiece to be processed, maintaining the cleanliness of the workpiece to be processed and improving the subsequent laser marking effect.

[0040] A control component is installed on the upper side of the first rack 13. The control component includes two slide rails 26 fixedly installed on the upper side of the first rack 13. Slide rods 27 are slidably arranged on the side walls of the two slide rails 26. The slide rods 27 are circumferentially slidably connected to the moving cylinder 25. A second torsion spring 23 is fixedly connected between the slider 28 and the transmission rod 24;

[0041] First, a rotating ring is fixedly connected to the outside of the two sliding rods 27. The rotating ring and the moving cylinder 25 are rotatably connected. When not all four rotating cylinders 14 are in contact with the workpiece to be processed, the stepped plate 16 will obstruct the first stop lever 32 that moves with the transmission rod 24. That is, when the first stop lever 32 is in contact with the stepped plate 16, it will cause the transmission rod 24 to rotate until the stepped plate 16 and the first stop lever 32 are disconnected. During this process, under the action of the second torsion spring 23, the transmission rod 24 will rotate back and forth. The transmission rod 24 drives the friction plate 15 to rotate back and forth, which will form a cleaning effect on the surface of the workpiece to be processed. When all four rotating cylinders 14 are in contact with the workpiece to be processed, at this time, under the obstruction of the workpiece to be processed, the entire transmission rod 24 stops moving with the first rack 13. While compressing the first spring 30, under the action of the slide rail 26, the moving cylinder 25 moves downward relative to the transmission rod 24. At this time, it will cause the stepped plate 16 and the first stop lever 32 to be disconnected. The moving stepped plate 16 will not be in contact with the first stop lever 32, thereby causing the transmission rod 24 to stop rotating. At this time, the friction plate 15 returns to its original position relative to the transmission rod 24;

[0042] During the process of the transmission rod 24 driving the friction plate 15 to rotate, since the friction plate 15, the moving rod 20 and the moving plate 22 are connected by the second spring 21 and the connecting plate 18, that is, the friction plate 15 can slide relative to the transmission rod 24. Therefore, when the distance between two adjacent rotating cylinders 14 becomes smaller and smaller, when the friction plate 15 is in contact with the adjacent rotating cylinder 14, it will cause the friction plate 15 to move, compressing the second spring 21 until the friction plate 15 and the adjacent rotating cylinder 14 are disconnected.

[0043] A rotating assembly is installed on the outside of the moving cylinder 25. The rotating assembly includes a control cylinder 33 rotatably installed on the upper side of the moving cylinder 25. Two second stop levers 31 are symmetrically and fixedly connected to the outside of the control cylinder 33. The control cylinder 33 rotatably penetrates through the lower side of the rotating cylinder 14. The upper side of the transmission rod 24 is fixedly connected with a top plate 17. The top plate 17 and the connecting plate 18 are fixedly connected. A first torsion spring 19 is fixedly connected between the top plate 17 and the rotating cylinder 14;

[0044] When the stepped plate 16 and the first shift lever 32 are disconnected, and the stepped plate 16 just abuts against the second shift lever 31, although the rotating cylinder 14 and the transmission rod 24 are in a stationary state as a whole at this time, the stepped plate 16 is still in a moving state. During this process, when the stepped plate 16 abuts against the second shift lever 31, it will cause the second shift lever 31 to rotate relative to the transmission rod 24. The second shift lever 31 drives the control cylinder 33 to rotate, and the control cylinder 33 drives the rotating cylinder 14 to rotate. All the rotating cylinders 14 abut against the workpiece to be processed. At this time, the rotating rotating cylinder 14 will cause the workpiece to be processed to rotate until the stepped plate 16 and the second shift lever 31 are disconnected. Under the action of the first torsion spring 19, during this process, the rotating cylinder 14 rotates back and forth as a whole, and the rotating cylinder 14 drives the workpiece to be processed to rotate back and forth. At this time, cooperating with the camera used to monitor the workpiece to be processed can improve the monitoring effect of the camera.

[0045] A plurality of spring hinges are fixedly connected to the lower side of the friction plate 15, and a cleaning cloth is fixedly connected to the lower sides of the plurality of spring hinges together;

[0046] During the back-and-forth rotation of the friction plate 15, the spring hinges on the lower side of the friction plate 15 abut against the cleaning cloth and the workpiece to be processed, forming a friction cleaning effect on the workpiece to be processed.

[0047] A bracket 4 is fixedly connected to the upper side of the main body 1, a feeding motor 5 is fixedly connected to the upper side of the bracket 4, there are two threaded rods 7, and a pulley assembly 6 is installed between the two threaded rods 7. The output shaft of the feeding motor 5 is fixedly connected to one of the threaded rods 7;

[0048] When the workpiece to be processed moves to the upper side of the feeding plate 3, the feeding motor 5 is started. The feeding motor 5 drives the threaded rod 7 to rotate. The threaded rod 7 drives the other threaded rod 7 to rotate through the pulley assembly 6, and finally drives the two threaded rods 7 to rotate simultaneously. Since both threaded rods 7 are threadedly connected to the feeding plate 3, the rotating threaded rod 7 will drive the feeding plate 3 to move up and down, providing power for the movement of the feeding plate 3.

[0049] A vertical clamping assembly is installed on the outer side of the rotating cylinder 14. The vertical clamping assembly includes a positioning ring 35 rotatably connected to the rotating cylinder 14. Two limiting arc-shaped rods 36 are fixedly connected to the side wall of the positioning ring 35. A sliding plate 47 is slidably connected to the outer side of the limiting arc-shaped rod 36. A third spring 50 is fixedly connected between the sliding plate 47 and the positioning ring 35. A fixed cylinder 37 is also fixedly connected between the two limiting arc-shaped rods 36. A clamping rod 38 is slidably connected in the fixed cylinder 37. An arc-shaped plate 39 is fixedly connected to the lower side of the clamping rod 38. A plurality of through holes 48 are formed in the side wall of the clamping rod 38. Fixed arc-shaped rods 46 are fixedly connected to the side walls of the two sliding plates 47. An installation arc-shaped rod 49 is fixedly connected to the side wall of one of the sliding plates 47. A notch 51 is formed in the side wall of the clamping rod 38. A stop block 52 is fixedly connected to the end of the installation arc-shaped rod 49. The side wall of the positioning ring 35 is fixedly connected to a connection ring 41 through a first connecting rod 40. A second connecting rod 42 is slidably penetrated through the connection ring 41. The second connecting rod 42 is fixedly connected to the first rack 13. A connecting plate 4318 is fixedly connected to the outer side of the second connecting rod 42. Two connecting cylinders 44 are fixedly connected to the outer side of the connecting plate 4318. A third connecting rod 45 is slidably connected in each of the two connecting cylinders 44. A buffer spring is fixedly connected between the third connecting rod 45 and the connecting cylinder 44;

[0050] First, in the initial state, the stop block 52 is located in the notch 51 and abuts against the inner wall of the notch 51. During the initial clamping process using the rotating cylinder 14, when the rotating cylinder 14 abuts against the workpiece to be processed, at this time, the rotating cylinder 14 and the positioning ring 35 as a whole stop moving. However, since the second connecting rod 42 is fixedly connected to the first rack 13 at this time and the first rack 13 is still in a moving state, the moving first rack 13 drives the connecting rod, the connecting cylinder 44 and the third connecting rod 45 to move through the second connecting rod 42. Based on the Figure 12 direction, at this time, the connecting rod, the connecting cylinder 44 and the third connecting rod 45 move to the right. The third connecting rod 45 abuts against the sliding rod 27, which causes the sliding plate 47 to slide along the limiting arc-shaped rod 36. The sliding plate 47 drives the installation arc-shaped rod 49 and the stop block 52 to move. The stop block 52 moves out of the notch 51. At this time, the clamping rod 38 and the arc-shaped plate 39 move downward under the action of their own gravity until the arc-shaped plate 39 abuts against the workpiece to be processed. At this time, the sliding plate 47 continues to slide along the limiting arc-shaped rod 36, and the sliding plate 47 drives the fixed arc-shaped rod 46 to move. The fixed arc-shaped rod 46 enters the through hole 48 to complete the fixing operation of the positions of the clamping rod 38 and the arc-shaped plate 39, and finally complete the vertical clamping and fixing effect on the workpiece to be processed.

[0051] In the present invention, first, when a marking operation is required, the workpiece to be processed is placed below the laser generator. A control system for controlling the operation of the laser generator is installed in the display screen. The control system is started through the display screen, and then the laser generator is started to start the marking operation. Moreover, a camera is installed on the front side of the display screen, and the substance of the workpiece and the changes of the workpiece during laser marking can be monitored through the camera. When a marking operation is required, the workpiece to be processed is placed on the conveyor belt, the conveyor motor is started, the conveyor motor drives the conveyor rod to rotate, and then drives the conveyor belt and the workpiece placed on the upper side of the conveyor belt to move until the workpiece moves below the laser generator, and then the corresponding laser marking operation can be started. When it is detected that the workpiece moves below the laser emitter, the control system can be automatically started. When it is detected that the workpiece processing is completed, the control system can be automatically turned off. The above are all prior arts and will not be elaborated further;

[0052] When the workpiece to be processed moves to the upper side of the loading plate 3, the loading motor 5 is started. The loading motor 5 drives the threaded rod 7 to rotate through the pulley assembly 6, and the loading plate 3 moves upward, shortening the distance between the workpiece to be processed and the laser emitter until the workpiece to be processed moves to a suitable processing position. During this process, the first gear 9 that moves with the loading plate 3 will also rotate under the action of the threaded rod 7. The first gear 9 drives the third gear 12 to rotate. The third gear 12 drives the second gear 11 to rotate through the rotating shaft 10. The second gear 11 drives the first rack 13 to move towards the loading plate 3. The first rack 13 drives the transmission rod 24 to move through the first spring 30 and the slider 28. The transmission rod 24 drives the outer rotating cylinder 14 to move. When one or several rotating cylinders 14 abut against the workpiece to be processed, under the extrusion action of the rotating cylinder 14, the workpiece to be processed will move towards the center point of the loading plate 3 until all the rotating cylinders 14 abut against the workpiece to be processed, thus completing the position adjustment and fixing operation of the workpiece to be processed;

[0053] During this process, the second gear 11 will also drive the second rack 34 to move away from the loading plate 3. The second rack 34 drives the stepped plate 16 to move through the right-angle rod. During the process of the transmission rod 24 following the first rack 13 to move the plate 22, the transmission rod 24 drives the moving cylinder 25 to move. The moving cylinder 25 drives the outer first stop rod 32 to move. When the first stop rod 32 abuts against the stepped plate 16, under the blocking action of the stepped plate 16, the moving cylinder 25 will rotate. The moving cylinder 25 drives the transmission rod 24 to rotate. The transmission rod 24 drives the friction plate 15 to rotate. The friction plate 15 will abut against the workpiece to be processed placed on the upper side of the loading plate 3, forming a friction cleaning effect on the workpiece to be processed, maintaining the cleanliness of the workpiece to be processed, and improving the subsequent laser marking effect;

[0054] When the four rotating cylinders 14 do not all abut against the workpiece to be processed, the stepped plate 16 will obstruct the first stop lever 32 that moves along with the transmission rod 24. That is, when the first stop lever 32 abuts against the stepped plate 16, it will cause the transmission rod 24 to rotate until the stepped plate 16 disconnects from the first stop lever 32. During this process, under the action of the second torsion spring 23, the transmission rod 24 will rotate back and forth. The transmission rod 24 drives the friction plate 15 to rotate back and forth, forming a cleaning effect on the surface of the workpiece to be processed. When all four rotating cylinders 14 abut against the workpiece to be processed, at this time, under the obstruction of the workpiece to be processed, the entire transmission rod 24 stops moving along with the first rack 13. While compressing the first spring 30, under the action of the slide rail 26, the moving cylinder 25 moves downward relative to the transmission rod 24. At this time, it will cause the stepped plate 16 to disconnect from the first stop lever 32. The moving stepped plate 16 will not abut against the first stop lever 32, thereby causing the transmission rod 24 to stop rotating. At this time, the friction plate 15 returns to its original position relative to the transmission rod 24;

[0055] When the stepped plate 16 disconnects from the first stop lever 32 and just abuts against the second stop lever 31, although the rotating cylinder 14 and the transmission rod 24 are in a stationary state as a whole at this time, the stepped plate 16 is still in a moving state. During this process, when the stepped plate 16 abuts against the second stop lever 31, it will cause the second stop lever 31 to rotate relative to the transmission rod 24. The second stop lever 31 drives the control cylinder 33 to rotate, and the control cylinder 33 drives the rotating cylinder 14 to rotate. All the rotating cylinders 14 abut against the workpiece to be processed. At this time, the rotating rotating cylinder 14 will cause the workpiece to be processed to rotate until the stepped plate 16 disconnects from the second stop lever 31. Under the action of the first torsion spring 19, during this process, the rotating cylinder 14 rotates back and forth as a whole. The rotating cylinder 14 drives the workpiece to be processed to rotate back and forth. At this time, cooperating with the camera used to monitor the workpiece to be processed can improve the monitoring effect of the camera;

[0056] During the initial clamping process using the rotating cylinder 14, when the rotating cylinder 14 abuts against the workpiece to be processed, at this time, the rotating cylinder 14 and the positioning ring 35 stop moving as a whole. However, since the second connecting rod 42 is fixedly connected to the first rack 13 at this time and the first rack 13 is still in a moving state, the moving first rack 13 drives the connecting rod, the connecting cylinder 44, and the third connecting rod 45 to move through the second connecting rod 42, so as to Figure 12Based on the direction of [description missing], at this time, the connecting rod, the connecting cylinder 44, and the third connecting rod 45 move to the right. When the third connecting rod 45 abuts against the sliding rod 27, it will cause the sliding plate 47 to slide along the limiting arc-shaped rod 36. The sliding plate 47 drives the mounting arc-shaped rod 49 and the stopper 52 to move, and the stopper 52 moves out of the notch 51. At this time, the clamping rod 38 and the arc-shaped plate 39 move downward under the action of their own gravity until the arc-shaped plate 39 abuts against the workpiece to be processed. At this time, the sliding plate 47 continues to slide along the limiting arc-shaped rod 36, and the sliding plate 47 drives the fixed arc-shaped rod 46 to move. The fixed arc-shaped rod 46 enters the through hole 48 to complete the fixing operation of the positions of the clamping rod 38 and the arc-shaped plate 39, and finally complete the vertical clamping and fixing effect on the workpiece to be processed.
