Description

Technical Field

[0001] This invention relates to the field of heat treatment technology, and in particular to a laser marking machine with an automatic feeding mechanism. Background Technology

[0002] Laser marking machines use laser beams to create permanent marks on the surfaces of various materials. The marking effect is achieved by evaporating the surface material to expose the deeper material, thereby engraving exquisite patterns, trademarks, and text. Traditional laser marking machines mainly consist of a laser generator, control system, and worktable, with a simple overall structure and low manufacturing cost.

[0003] In actual processing, traditional laser marking machines lack a feeding mechanism, requiring manual feeding, which is time-consuming and labor-intensive. Furthermore, before laser marking, the position of the workpiece must be manually calibrated, which is very troublesome. Moreover, the surface of the workpiece must be kept clean at all times before processing to maintain the subsequent marking quality. Finally, during processing, monitoring of the workpiece is mainly achieved through a camera. However, since the workpiece is stationary, there are blind spots in the camera, making it impossible to perfectly capture its actual condition, requiring constant manual supervision. Therefore, this paper proposes a laser marking machine with an automatic feeding mechanism. Summary of the Invention

[0014] The beneficial effects of this invention are:

[0015] 1. First, before performing laser marking, start the feeding motor, which will drive the feeding plate and the workpiece to be processed to move upward together. During this process, the four rotating cylinders that follow the feeding plate to move upward will also move towards the center of the feeding plate until all the rotating cylinders are in contact with the workpiece to be processed, thereby completing the adjustment and fixing of the position of the workpiece to be processed.

[0016] 2. At the same time, during this process, after the rotating cylinder and the workpiece come into contact, the clamping rod and the arc plate will automatically fall. When the arc plate comes into contact with the workpiece, it will automatically form a positioning effect on the clamping rod. Finally, the arc plate will form a vertical clamping and fixing effect on the workpiece. It can also be automatically adjusted according to the actual working conditions to complete the clamping and fixing operation of workpieces of different heights.

[0017] 3. During the feeding process, the transmission rod drives the friction plate to rotate. The friction plate will come into contact with the workpiece to be processed placed on the upper side of the feeding plate, forming a friction cleaning of the workpiece to be processed, keeping the workpiece clean and improving the subsequent laser marking effect.

[0018] 4. At the same time, the rotating drum rotates back and forth, which drives the workpiece to be processed to rotate back and forth. At this time, the camera used to monitor the workpiece can improve the monitoring effect. The structure is simple and the overall automation and intelligence level is high.

Detailed Implementation

[0033] See Figures 1-13 A laser marking machine with an automatic feeding mechanism includes a body 1, a display screen mounted on the upper side of the body 1, and a laser generator mounted on the upper side of the body 1.

[0034] First, when marking is required, the object to be processed is placed under the laser generator. The display screen contains a control system that controls the operation of the laser generator. The control system is activated through the display screen, which in turn starts the laser generator, and the marking operation begins. A camera is installed on the front of the display screen, which can monitor the material of the object and its changes during laser marking. When the object is detected to have moved to the underside of the laser emitter, the control system can be automatically activated. When the object is detected to have been processed, the control system can be automatically deactivated. The above are all existing technologies and will not be elaborated further.

[0035] A transport component 2 is installed on the upper side of the main body 1. The transport component 2 includes a transport motor fixedly installed on the upper side of the main body 1. Two clamping plates are fixedly connected to the upper side of the main body 1. Multiple transport rods are rotatably connected between the two clamping plates. A transport belt is sleeved on the outer side of the multiple transport rods. A tensioning wheel that can adjust the tension of the transport belt is also installed inside the clamping plate. One of the transport rods is fixedly connected to the output shaft of the transport motor.

[0036] When marking is required, the object to be processed is placed on the conveyor belt, the conveyor motor is started, the conveyor motor drives the conveyor rod to rotate, which in turn drives 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 the corresponding laser marking operation can be started. This technology is also an existing and publicly available technology, so it will not be described in detail.

[0037] A feeding assembly is installed on the upper side of the main body 1. The feeding assembly includes two threaded rods 7 rotatably mounted on the upper side of the main body 1. A feeding plate 3 is threadedly connected to the outer side of the two threaded rods 7. A first gear 9 is slidably connected to the outer side of each of the two threaded rods 7. The first gear 9 is rotatably mounted on the lower side of the feeding plate 3. Four inclined slots 8 are symmetrically opened on the upper side of the feeding plate 3. Four first racks 13 and second racks 34 are slidably connected inside the feeding plate 3. The position and number of the four first racks 13 and four second racks 34 are opposite to the inclined slots 8. Four rotating shafts 10 are rotatably connected within the material plate 3. A second gear 11 is fixedly connected to the upper side of each rotating shaft 10. A first rack 13 and a second rack 34 mesh with the second gear 11. A third gear 12 is fixedly connected to the lower side of each rotating shaft 10, meshing with the first gear 9. A sliding groove 29 is formed on the upper side of each first rack 13, and a slider 28 is slidably connected within each groove 29. A first spring 30 is fixedly connected between the slider 28 and the groove 29. The outer side of the slider 28 rotates... A transmission rod 24 is dynamically connected, and a movable cylinder 25 is slidably connected to the outside of the transmission rod 24. Two first stop rods 32 are fixedly connected to the outside of the movable 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 via a right-angle rod. A rotating cylinder 14 is rotatably connected to the outside of the transmission rod 24. A friction plate 15 is connected to the outside of the transmission rod 24 via a sliding assembly. Multiple rubber protrusions are fixedly connected to the outside of the rotating cylinder 14 to provide friction for the rotating cylinder 14, thereby enabling more... The good formation of the control operation of the workpiece to be processed includes a sliding assembly including a top plate 17 fixedly installed on the upper side of the transmission rod 24, a first torsion spring 19 fixedly connected between the top plate 17 and the rotating cylinder 14, a connecting plate 18 fixedly connected to the side wall of the top plate 17, a plurality of moving rods 20 slidably connected to the side wall of the connecting plate 18, each moving rod 20 being fixedly connected to the friction plate 15, and a moving plate 22 fixedly connected to the outer side of each moving rod 20, and a second spring 21 fixedly connected between the moving plate 22 and the connecting plate 18;

[0038] Initially, the loading plate 3 and the conveyor belt abut against each other, initiating an installation operation on the conveyor belt. As the conveyor belt transports the workpiece, it moves to the upper side of the loading plate 3 under the belt's influence. Then, when the threaded rod 7 rotates, the loading plate 3 moves upward, shortening the distance between the workpiece and the laser emitter until the workpiece reaches the appropriate processing position. During this process, the first gear 9, which moves with the loading plate 3, also rotates under the action of the threaded rod 7. The first gear 9 drives the third gear 12 to rotate. Gear 12 drives the second gear 11 to rotate via shaft 10. The second gear 11 drives the first rack 13 to move towards the feed plate 3. The first rack 13 drives the transmission rod 24 to move via the first spring 30 and slider 28. The transmission rod 24 drives the outer rotating cylinder 14 to move. When one or more rotating cylinders 14 come into contact with the workpiece to be processed, the workpiece to be processed will move towards the center point of the feed plate 3 under the squeezing action of the rotating cylinders 14 until all rotating cylinders 14 come into contact with the workpiece to be processed, thereby completing the adjustment and fixing 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. As the transmission rod 24 moves with the first rack 13, 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 and the stepped plate 16 come into contact, the moving cylinder 25 will rotate due to the obstruction of the stepped plate 16. The moving cylinder 25 drives the transmission rod 24 to rotate, and the transmission rod 24 drives the friction plate 15 to rotate. The friction plate 15 will come into contact with the workpiece to be processed placed on the upper side of the loading plate 3, forming a friction cleaning of the workpiece to be processed, keeping the workpiece clean 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 slide on the side walls of the two slide rails 26. Slide rods 27 and moving cylinder 25 are circumferentially connected. A second torsion spring 23 is fixedly connected between slider 28 and transmission rod 24.

[0041] First, a rotating ring is fixedly connected to the outer side of both 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, the step plate 16 will obstruct the movement of the first stop 32 that follows the transmission rod 24. That is, when the first stop 32 and the step plate 16 are in contact, the transmission rod 24 will rotate until the step plate 16 and the first stop 32 are disconnected. During this process, under the action of the second torsion spring 23, the transmission rod 24 will rotate back and forth, and the transmission rod 24 will drive the friction plate 15 to rotate back and forth. The movement creates a cleaning effect on the surface of the workpiece. When all four rotating cylinders 14 are in contact with the workpiece, the transmission rod 24 stops moving along with the first rack 13 due to the obstruction of the workpiece. While compressing the first spring 30, the moving cylinder 25 moves downward relative to the transmission rod 24 under the action of the slide rail 26. This causes the stepped plate 16 to disconnect from the first stop rod 32. The moving stepped plate 16 will not contact the first stop rod 32, thus 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 rotation of the friction plate 15 driven by the transmission rod 24, 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, the friction plate 15 and the adjacent rotating cylinder 14 come into contact, which will cause the friction plate 15 to move and compress the second spring 21 until the connection between the friction plate 15 and the adjacent rotating cylinder 14 is broken.

[0043] A rotating assembly is installed on the outside of the movable cylinder 25. The rotating assembly includes a control cylinder 33 rotatably mounted on the upper side of the movable cylinder 25. Two second stop rods 31 are symmetrically fixedly connected to the outside of the control cylinder 33. The control cylinder 33 rotatably passes through the lower side of the rotating cylinder 14. A top plate 17 is fixedly connected to the upper side of the transmission rod 24. 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 step plate 16 and the first stop bar 32 are disconnected, the step plate 16 and the second stop bar 31 just come into contact. At this time, although the rotating cylinder 14 and the transmission rod 24 are stationary, the step plate 16 is still moving. During this process, when the step plate 16 and the second stop bar 31 come into contact, the second stop bar 31 will rotate as equivalent to the transmission rod 24. The second stop bar 31 will drive the control cylinder 33 to rotate, and the control cylinder 33 will drive the rotating cylinder 14 to rotate. All the rotating cylinders 14 will come into contact with the workpiece to be processed. At this time, the rotating rotating cylinders 14 will cause the workpiece to rotate until the step plate 16 and the second stop bar 31 are disconnected. Under the action of the first torsion spring 19, the rotating cylinder 14 will rotate back and forth during this process, and the rotating cylinder 14 will drive the workpiece to rotate back and forth. At this time, the monitoring effect of the camera used to monitor the workpiece to be processed can be improved.

[0045] Multiple spring flaps are fixedly connected to the lower side of the friction plate 15, and a cleaning cloth is fixedly connected to the lower side of the multiple spring flaps.

[0046] As the friction plate 15 rotates back and forth, the spring flaps on the lower side of the friction plate 15 come into contact with the cleaning cloth and the workpiece to be processed, creating a friction cleaning effect on the workpiece.

[0047] A bracket 4 is fixedly connected to the upper side of the main body 1, and 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 loading plate 3, the loading motor 5 is started. The loading motor 5 drives the threaded rod 7 to rotate. The threaded rod 7 drives another threaded rod 7 to rotate through the pulley assembly 6. Finally, both threaded rods 7 rotate simultaneously. Since both threaded rods 7 are threadedly connected to the loading plate 3, the rotating threaded rods 7 will drive the loading plate 3 to move up and down, providing power for the movement of the loading 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 rods 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 inside the fixed cylinder 37. An arc-shaped plate 39 is fixedly connected to the lower side of the clamping rod 38. Multiple through holes 48 are opened on the side wall of the clamping rod 38. Fixed arc-shaped rods 46 are fixedly connected to the side walls of both sliding plates 47. A mounting arc rod 49 is fixedly connected to the side wall of a sliding plate 47. A notch 51 is opened on the side wall of a clamping rod 38. A stop block 52 is fixedly connected to the end of the mounting arc rod 49. A connecting ring 41 is fixedly connected to the side wall of a positioning ring 35 through a first connecting rod 40. A second connecting rod 42 is slidably connected to the connecting ring 41. The second connecting rod 42 is fixedly connected to the first rack 13. A connecting plate 43 is fixedly connected to the outside of the second connecting rod 42. Two connecting cylinders 44 are fixedly connected to the outside of the connecting plate 43. A third connecting rod 45 is slidably connected inside 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] Initially, the stop block 52 is located inside 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, the rotating cylinder 14 and the positioning ring 35 stop moving as a whole. However, since the second connecting rod 42 and the first rack 13 are fixedly connected at this time, the first rack 13 is still in a moving state. Therefore, the moving first rack 13 drives the connecting rod, connecting cylinder 44, and third connecting rod 45 to move through the second connecting rod 42. Figure 12 Based on the direction, the connecting rod, connecting cylinder 44, and third connecting rod 45 move to the right. The third connecting rod 45 and slide rod 27 abut against each other, causing the slide plate 47 to slide along the limiting arc rod 36. The slide plate 47 drives the installation arc 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 plate 39 move downward under their own weight until the arc plate 39 abuts against the workpiece to be processed. At this time, the slide plate 47 continues to slide along the limiting arc rod 36, and the slide plate 47 drives the fixed arc rod 46 to move. The fixed arc rod 46 enters the through hole 48, completing the fixing operation of the clamping rod 38 and the arc plate 39, and finally completing the vertical clamping and fixing effect of the workpiece to be processed.

[0051] In this invention, when marking is required, the object to be processed is placed under the laser generator. A control system for controlling the laser generator is installed in the display screen. The control system is activated through the display screen, which in turn activates the laser generator to begin the marking operation. A camera is installed on the front of the display screen to monitor the material of the object and its changes during laser marking. When marking is required, the object to be processed is placed on a conveyor belt, and the conveyor motor is started. The conveyor motor drives the conveyor rod to rotate, which in turn moves the conveyor belt and the object placed on the conveyor belt until the object moves to the underside of the laser generator, at which point the corresponding laser marking operation begins. When the object moves to the underside of the laser generator, the control system can be automatically activated. When the object processing is completed, the control system can be automatically deactivated. The above are all existing technologies and will not be described in detail.

[0052] When the workpiece 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. The loading plate 3 moves upward, shortening the distance between the workpiece and the laser emitter until the workpiece moves to the appropriate processing position. During this process, the first gear 9, which 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 closer to 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 more rotating cylinders 14 come into contact with the workpiece, the workpiece will move closer to the center point of the loading plate 3 under the squeezing action of the rotating cylinders 14 until all rotating cylinders 14 come into contact with the workpiece, thus completing the adjustment and fixing operation of the position of the workpiece.

[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. As the transmission rod 24 moves the plate 22 along with the first rack 13, 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 and the stepped plate 16 come into contact, the moving cylinder 25 will rotate due to the obstruction of the stepped plate 16. 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 come into contact with 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, keeping the workpiece clean and improving the subsequent laser marking effect.

[0054] When not all four rotating cylinders 14 are in contact with the workpiece, the stepped plate 16 will obstruct the movement of the first stop 32, which follows the transmission rod 24. That is, when the first stop 32 and the stepped plate 16 come into contact, the transmission rod 24 will rotate until the stepped plate 16 and the first stop 32 are disconnected. During this process, under the action of the second torsion spring 23, the transmission rod 24 will rotate back and forth, which will drive the friction plate 15 to rotate back and forth, thus creating a cleaning effect on the surface of the workpiece. When all four rotating cylinders 14 are in contact with the workpiece, the transmission rod 24 stops moving along with the first rack 13 due to the obstruction of the workpiece. While compressing the first spring 30, the moving cylinder 25 moves downward relative to the transmission rod 24 under the action of the slide rail 26. This causes the step plate 16 to disconnect from the first stop rod 32. The moving step plate 16 will not be in contact with the first stop rod 32, which will cause 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 step plate 16 and the first stop bar 32 are disconnected, the step plate 16 and the second stop bar 31 just come into contact. At this time, although the rotating cylinder 14 and the transmission rod 24 are stationary, the step plate 16 is still moving. During this process, when the step plate 16 and the second stop bar 31 come into contact, the second stop bar 31 will rotate as equivalent to the transmission rod 24. The second stop bar 31 will drive the control cylinder 33 to rotate, and the control cylinder 33 will drive the rotating cylinder 14 to rotate. All the rotating cylinders 14 will come into contact with the workpiece to be processed. At this time, the rotating rotating cylinders 14 will cause the workpiece to rotate until the step plate 16 and the second stop bar 31 are disconnected. Under the action of the first torsion spring 19, the rotating cylinder 14 will rotate back and forth during this process, and the rotating cylinder 14 will drive the workpiece to rotate back and forth. At this time, the monitoring effect of the camera used to monitor the workpiece to be processed can be improved.

[0056] During the initial clamping process using the rotating cylinder 14, when the rotating cylinder 14 comes into contact with the workpiece, the rotating cylinder 14 and the positioning ring 35 stop moving as a whole. However, since the second connecting rod 42 and the first rack 13 are fixedly connected at this time, the first rack 13 is still in a moving state. Therefore, the moving first rack 13 drives the connecting rod, connecting cylinder 44, and third connecting rod 45 to move through the second connecting rod 42. Figure 12Based on the direction, the connecting rod, connecting cylinder 44, and third connecting rod 45 move to the right. The third connecting rod 45 and slide rod 27 abut against each other, causing the slide plate 47 to slide along the limiting arc rod 36. The slide plate 47 drives the installation arc 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 plate 39 move downward under their own weight until the arc plate 39 abuts against the workpiece to be processed. At this time, the slide plate 47 continues to slide along the limiting arc rod 36, and the slide plate 47 drives the fixed arc rod 46 to move. The fixed arc rod 46 enters the through hole 48, completing the fixing operation of the clamping rod 38 and the arc plate 39, and finally completing the vertical clamping and fixing effect of the workpiece to be processed.
