Description

Technical Field

[0001] The invention relates to the technical field of laser marking, and more particularly to a metal pipe assembly and laser marking device. Background Art

[0002] In modern industrial production, metal pipe fittings are widely used as key components in automobile manufacturing, aerospace, petrochemical, mechanical equipment and other fields. The quality of metal pipe fittings and the accuracy of identification information are directly related to the traceability, safety and overall performance of the product. With the continuous improvement of industrial automation and intelligent level, higher requirements are put forward for the production efficiency and processing accuracy of metal pipe fittings, especially in the assembly and laser marking of metal pipe fittings.

[0003] In the traditional metal pipe assembly and marking process, the metal pipes are first assembled accurately according to the design requirements through a dedicated assembly device. This process usually relies on equipment such as robotic arms, fixtures, and precision positioning systems to ensure assembly accuracy and stability. However, after assembly, the metal pipes often need to be transferred to another independent laser marking machine for marking. This segmented operation mode not only increases the cost of material handling and transfer, but also leads to a significant reduction in production efficiency.

[0004] More importantly, existing laser marking technologies are mostly limited to single-sided marking of metal pipes. For pipes that need double-sided marking, secondary handling or repositioning is often required, which not only increases the complexity of the operation, but also may affect the accuracy and consistency of the marking due to repeated positioning errors. In addition, multiple handling may also cause potential damage to the assembled pipe structure, affecting product quality.

[0005] In view of the above technical bottlenecks, the market urgently needs a device that can integrate metal pipe assembly and double-sided laser marking to achieve an efficient, accurate and continuous automated production process. In view of this, we propose a metal pipe assembly and laser marking device. Summary of the invention

[0016] Preferably, the present invention also provides a method of use, comprising the following steps: S1, loading operation; The metal pipe fittings are transported to the bottom of the first grabbing mechanism on the vibrating loading tray, and then the first grabbing mechanism moves the metal pipe fittings to be assembled and marked to the first pipe fitting magnetic seat and the second pipe fitting magnetic seat of the rotating bearing table; S2, adjustment operation; The driving motor rotates forward and reversely to drive the eccentric elliptical block to rotate, and the eccentric elliptical block squeezes the ratchet and the spring, so that the ratchet on one side is disengaged from the ratchet wheel, so that the ratchet wheel is locked in the forward clockwise direction or in the reverse counterclockwise direction, thereby fixing the inner slide rod and pushing the outer cylinder to move; S3, assembly operation; The servo motor is driven to drive the output shaft to rotate, and the output shaft drives the guide shaft to rotate. The propulsion spiral guide groove on the guide shaft first drives the fixed inner slide rod to rotate and move, and the fixed inner slide rod drives the propulsion outer cylinder to rotate and move. When one of the metal pipes on the first pipe magnetic seat is pushed to contact another metal pipe on the second pipe magnetic seat, the fixed inner slide rod slides to the spiral guide groove of the rotation group. Since the stroke of the spiral guide groove of the rotation group is short and the number of spiral turns is large, the fixed inner slide rod and the propulsion outer cylinder move a short distance and rotate multiple turns. The propulsion outer cylinder drives the first pipe magnetic seat and one of the metal pipes magnetically attracted thereon to be threadedly rotated and connected to another metal pipe. S4, rotation displacement operation; The assembled metal pipe is rotated to the position directly below the laser marking mechanism by means of a rotating bearing platform, and the front side is laser marked by means of the laser marking mechanism; S5, flip operation; When one side is marked, the cylinder stroke is driven to drive the push rod to move until the push rod is inserted into the fixed outer ring to achieve synchronous locking adjustment. At this time, the servo motor drives the output shaft to rotate, and the output shaft drives the ratchet to rotate. Since the ratchet is clamped on the ratchet, the ratchet cannot rotate in this direction, so the outer ring tube is synchronously driven to rotate as a whole. The outer ring tube drives the cylinder and the push rod to rotate. Since the push rod is inserted into the fixed outer ring, the outer cylinder is synchronously driven to rotate. The outer cylinder drives the first pipe magnetic seat and one of the magnetically attracted metal pipes on it to rotate. Since the metal pipe has been assembled at this time, it drives the other metal pipe to flip 180 degrees on the second pipe magnetic seat to achieve flipping and laser marking on the reverse side through the laser marking mechanism again. S6, unloading operation; The marked metal pipe is rotated to the position directly below the second gripping mechanism by the rotating carrier, and the processed metal pipe is transported to the discharge box by the second gripping mechanism for discharge.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention conveys the metal pipe fittings to the bottom of the first grabbing mechanism through a vibrating loading tray, and transports the metal pipe fittings to the rotary assembly marking integrated mechanism on the rotating bearing table through the first grabbing mechanism. First, the two metal pipe fittings are assembled by rotational threads through the rotary assembly marking integrated mechanism, and then the assembled metal pipe fittings are rotated to the bottom of the laser marking mechanism through the rotating bearing table for laser marking. After the marking of one side is completed, the metal pipe fittings are turned over by the rotary assembly marking integrated mechanism to mark the other side. The present invention integrates the assembly and marking functions on the production line of the same equipment, reduces the number of material transfers, shortens the production cycle, and improves the processing efficiency of metal pipe fittings.

[0018] 2. The present invention can achieve high-precision positioning of metal pipes through integrated design, ensure accuracy and stability during the assembly process, avoid potential damage to the assembled pipe structure caused by multiple handlings, ensure the integrity of the product while avoiding the impact on subsequent marking due to bumps.

[0019] 3. The present invention can automatically complete the marking of both sides of metal pipes within one production cycle without secondary handling or repositioning. Double-sided marking is completed simultaneously, which reduces the waiting time in the production process and significantly improves production efficiency.

[0020] 4. The stroke of the reverse spiral groove in the present invention is greater than that of the advancing spiral guide groove, and the number of spiral turns is also less than that of the advancing spiral guide groove. This design enables the object to move quickly along the reverse spiral groove when retreat is required, greatly shortening the retreat time and improving the overall movement efficiency. It also helps to reduce friction resistance during the retreat process, allowing the object to move more smoothly, further improving the movement efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention conveys the metal pipe fittings to the bottom of the first grabbing mechanism 5 through the vibrating loading tray 3, and transports the metal pipe fittings to the rotary assembly marking integrated mechanism 8 on the rotating supporting platform 7 through the first grabbing mechanism 5.

The present invention integrates the assembly and marking functions on the production line of the same equipment, reduces the number of material transfers, shortens the production cycle, and improves the processing efficiency of metal pipe fittings.

[0026] In the embodiment of the present invention, the bearing drive assembly 801 includes a supporting plate 8011, a servo motor 8012 and an output shaft 8013. The supporting plate 8011 is arranged on the rotating bearing platform 7 in an annular shape and at equal intervals. The servo motor 8012 is arranged on the supporting plate 8011. The output shaft 8013 is connected to the output end of the servo motor 8012. The output shaft 8013 is connected to the rotating guide assembly 802 at one end away from the servo motor 8012. The supporting plate 8011 of the present invention is provided with four supporting plates 8011 at equal intervals in an annular shape. The servo motor 8012 is fixedly arranged at the top of the supporting plate 8011. The output shaft 8013 is driven to rotate by the servo motor 8012, and the output shaft 8013 drives the rotating guide assembly 802 to rotate.

[0027] In an embodiment of the present invention, the rotary guide assembly 802 includes a guide shaft 8021, a propulsion spiral guide groove 8022, a spiral group spiral guide groove 8023, and a reverse spiral back groove 8024. The guide shaft 8021 is connected to the end of the output shaft 8013 away from the servo motor 8012, the propulsion spiral guide groove 8022 is arranged on the outer wall of the guide shaft 8021 close to the end of the output shaft 8013, the spiral group spiral guide groove 8023 is arranged on the outer wall of the guide shaft 8021 away from the end of the output shaft 8013, and the reverse spiral back groove 8024 is arranged on the outer wall of the guide shaft 8021. The propulsion spiral guide groove 8022, the spiral group spiral guide groove 8023, and the reverse spiral back groove 8024 are interconnected; wherein, the propulsion spiral guide groove 8022 and the spiral group spiral guide groove 8023 are spirals in the same direction, and the propulsion spiral guide groove 8022, the spiral group spiral guide groove 8023, and the reverse spiral back groove 8024 are spirals in opposite directions.

[0028] like Fig.13 As shown, the stroke of the advancing spiral guide groove 8022 on the guide shaft 8021 of the present invention is greater than that of the spiral guide groove 8023, the stroke of the reverse spiral retreat groove 8024 is greater than that of the advancing spiral guide groove 8022, the number of spiral turns of the advancing spiral guide groove 8022 is less than that of the spiral guide groove 8023, and the number of spiral turns of the reverse spiral retreat groove 8024 is less than that of the advancing spiral guide groove 8022.

[0029] In an embodiment of the present invention, the rotary propulsion assembly 804 includes a propulsion outer cylinder 8041, a fixed inner slide rod 8042 and a fixed outer ring 8043. The propulsion outer cylinder 8041 is movably sleeved on the guide shaft 8021, the fixed inner slide rod 8042 is fixed on the inner wall of the propulsion outer cylinder 8041, the fixed outer ring 8043 is fixed on the outer wall of the propulsion outer cylinder 8041, and one end of the fixed inner slide rod 8042 away from the propulsion outer cylinder 8041 is movably inserted into the propulsion spiral guide groove 8022, the rotation group spiral guide groove 8023 and the reverse spiral withdrawal groove 8024.

[0030] In the present invention, the fixed inner slide bar 8042 fixedly arranged on the inner wall of the propulsion outer cylinder 8041 is movably inserted into the propulsion spiral guide groove 8022, the spiral guide groove 8023 and the reverse spiral groove 8024 of the guide shaft 8021, and the end of the propulsion outer cylinder 8041 away from the output shaft 8013 is connected to the first pipe magnetic seat 806, and the first pipe magnetic seat 806 is movably sleeved on the second pipe magnetic seat 807. Therefore, when the guide shaft 8021 rotates, the propulsion spiral guide groove 8022 on the guide shaft 8021 first pushes the fixed inner slide bar 8042 to rotate and move, and the fixed inner slide bar 8042 drives the propulsion outer cylinder 8041 to rotate and move. When one of the metal pipes on the first pipe magnetic seat 806 is pushed to contact another metal pipe on the second pipe magnetic seat 807, the fixed inner slide bar 8042 slides onto the spiral guide groove 8023 of the rotation group. Since the stroke of the spiral guide groove 8023 is short and the number of spiral turns is large, the fixed inner slide bar 8042 and the propulsion outer cylinder 8041 move a shorter distance and rotate multiple turns. The propulsion outer cylinder 8041 drives the first pipe magnetic seat 806 and one of the metal pipes magnetically attracted thereon to rotate and connect to the other metal pipe through a thread.

[0031] In an embodiment of the present invention, the ratchet assembly 803 includes an outer ring cylinder 8031, a ratchet 8032, a ratchet tooth 8033, a spring 8034, a motor 8035 and an eccentric elliptical block 8036. The outer ring cylinder 8031 ​​is movably mounted on the output shaft 8013, the ratchet 8032 is fixedly mounted on the output shaft 8013, one end of the ratchet tooth 8033 is hingedly connected to the inner wall of the outer ring cylinder 8031, and the other end of the ratchet tooth 8033 is movably engaged with the outer wall of the ratchet wheel 8032. One end of the spring 8034 is connected to the inner wall of the outer ring cylinder 8031, and the other end of the spring 8034 is connected to the ratchet tooth 8033. The motor 8035 is arranged on the outer wall of the outer ring cylinder 8031, and the eccentric elliptical block 8036 is connected to the output end of the motor 8035 near the ratchet tooth 8033. The ratchet 8033 and spring 8034 in the present invention are symmetrically arranged at the bottom end of the outer ring tube 8031, and the other end is movably engaged with the ratchet 8032. The eccentric elliptical block 8036 is driven to rotate forward and reversely by driving the motor 8035. The eccentric elliptical block 8036 squeezes the ratchet 8033 and the spring 8034, so that the ratchet 8033 on one side is disengaged from the ratchet 8032, so that the ratchet 8032 is locked in the forward clockwise direction or reverse counterclockwise direction, thereby fixing the inner slide rod 8042 and pushing the outer tube 8041 to move in both directions.

[0032] As another embodiment of the present invention, the fixing assembly 805 includes a cylinder 8051 and a push rod 8052. The cylinder 8051 is fixed on the outer wall of the outer ring tube 8031.

In the present invention, when the metal pipe is assembled, the cylinder 8051 is driven to stroke, driving the push rod 8052 to move until the push rod 8052 is inserted into the fixed outer ring 8043 to achieve synchronous locking adjustment. At this time, the servo motor 8012 drives the output shaft 8013 to rotate, and the output shaft 8013 drives the ratchet 8032 to rotate. Since the ratchet 8033 is clamped on the ratchet 8032, the ratchet 8032 cannot rotate in this direction, so the outer ring tube 8031 ​​is synchronously driven to rotate. The outer ring tube 8031 ​​drives the cylinder 8051 and the push rod 8052 to rotate. Since the push rod 8052 is inserted on the fixed outer ring 8043, it drives the outer cylinder 8041 to rotate synchronously. The outer cylinder 8041 drives the first pipe magnetic seat 806 and one of the magnetically attracted metal pipes thereon to rotate. Since the metal pipe has been assembled at this time, it drives the other metal pipe to flip 180 degrees on the second pipe magnetic seat 807 to achieve the flipping function.

[0033] As another embodiment of the present invention, a first tube groove 8061 is provided on the first tube magnetic seat 806, a marking through hole 8062 is provided on the first tube groove 8061, a fixed insert tube 8063 is provided at one end of the first tube magnetic seat 806 close to the second tube magnetic seat 807, and a movable slot 8064 is provided on the fixed insert tube 8063.

[0034] As another embodiment of the present invention, a second tube groove 8071 is opened on the second tube magnetic seat 807 , and a fixed rod 8072 is fixedly provided on one end of the second tube magnetic seat 807 close to the first tube magnetic seat 806 , and the fixed rod 8072 is movably inserted in the movable slot 8064 .

[0035] In the present invention, when the outer cylinder 8041 is pushed to drive the first pipe magnetic seat 806 and one of the magnetically attracted metal pipes thereon to flip, since the movable slot 8064 of the fixed insert tube 8063 and the fixed insert rod 8072 of the second pipe magnetic seat 807 are movably plugged in, the assembled metal pipe and the first pipe magnetic seat 806 are flipped synchronously, and then the metal pipe is double-sidedly marked through the marking hole 8062 by the laser marking mechanism 9.

[0036] Working principle: This embodiment provides a method for assembling a metal pipe and using a laser marking device, comprising the following steps: S1, loading operation; The metal pipe is transported to the bottom of the first grabbing mechanism 5 on the vibrating loading tray 3, and then the first grabbing mechanism 5 moves the metal pipe to be assembled and marked to the first pipe magnetic seat 806 and the second pipe magnetic seat 807 on the rotating bearing platform 7; S2, adjustment operation; The driving motor 8035 rotates forward and reversely to drive the eccentric elliptical block 8036 to rotate, and the eccentric elliptical block 8036 squeezes the ratchet 8033 and the spring 8034, so that the ratchet 8033 on one side is disengaged from the ratchet wheel 8032, so that the ratchet wheel 8032 is locked in the forward clockwise direction or in the reverse counterclockwise direction, thereby fixing the inner slide rod 8042 and pushing the outer cylinder 8041 to move; S3, assembly operation; The servo motor 8012 is driven to drive the output shaft 8013 to rotate, and the output shaft 8013 drives the guide shaft 8021 to rotate. The propulsion spiral guide groove 8022 on the guide shaft 8021 first pushes the fixed inner slide bar 8042 to rotate and move, and the fixed inner slide bar 8042 drives the propulsion outer cylinder 8041 to rotate and move. When one of the metal pipes on the first pipe magnetic seat 806 is pushed to contact another metal pipe on the second pipe magnetic seat 807, the fixed inner slide bar 8042 slides onto the spiral guide groove 8023 of the rotation group. Since the stroke of the spiral guide groove 8023 of the rotation group is short and the number of spiral turns is large, the fixed inner slide bar 8042 and the propulsion outer cylinder 8041 move a short distance and rotate multiple turns. The propulsion outer cylinder 8041 drives the first pipe magnetic seat 806 and one of the metal pipes magnetically attracted thereon to be threadedly rotated and connected to another metal pipe. S4, rotation displacement operation; The assembled metal pipe is rotated to the position directly below the laser marking mechanism 9 by rotating the bearing platform 7, and the front side is laser marked by the laser marking mechanism 9; S5, flip operation; When one side is marked, the cylinder 8051 is driven to move, and the push rod 8052 is driven to move until the push rod 8052 is inserted into the fixed outer ring 8043 to achieve synchronous locking adjustment. At this time, the servo motor 8012 drives the output shaft 8013 to rotate, and the output shaft 8013 drives the ratchet 8032 to rotate. Since the ratchet 8033 is clamped on the ratchet 8032, the ratchet 8032 cannot rotate in this direction, so the outer ring cylinder 8031 ​​is synchronously driven to rotate as a whole. The cylinder 8051 and the push rod 8052 are driven to rotate. Since the push rod 8052 is inserted on the fixed outer ring 8043, the outer cylinder 8041 is driven to rotate synchronously. The outer cylinder 8041 drives the first pipe magnetic seat 806 and one of the magnetically attracted metal pipes thereon to rotate. Since the metal pipe has been assembled at this time, the other metal pipe is driven to flip 180 degrees on the second pipe magnetic seat 807, and the flip is realized and the reverse side is laser marked again by the laser marking mechanism 9. S6, unloading operation; The marked metal pipe is rotated to the position directly below the second grabbing mechanism 6 by rotating the carrier platform 7 , and the processed metal pipe is transported to the discharge box 4 by the second grabbing mechanism 6 for discharge.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.

The propulsion spiral guide groove (8022) on the guide shaft (8021) first pushes the fixed inner slide bar (8042) to rotate and move, and the fixed inner slide bar (8042) drives the propulsion outer cylinder (8041) to rotate and move. When one of the metal pipes on the first pipe magnetic seat (806) is pushed to contact the second pipe magnetic seat (80 7), the fixed inner slide bar (8042) slides onto the spiral guide groove (8023) of the rotating assembly. Since the stroke of the spiral guide groove (8023) is short and the number of spiral turns is large, the fixed inner slide bar (8042) and the push outer cylinder (8041) move a short distance and rotate multiple times.

At this time, the servo motor (8012) drives the output shaft (8013) to rotate, and the output shaft (8013) drives the ratchet (8032) to rotate. Since the ratchet (8033) is clamped on the ratchet (8032), the ratchet (8032) cannot rotate in this direction, so the outer ring cylinder (8031) is synchronously driven to rotate as a whole, and the outer ring cylinder (8043) is driven to rotate. 031) drives the cylinder (8051) and the push rod (8052) to rotate. Since the push rod (8052) is inserted on the fixed outer ring (8043), it synchronously drives the outer cylinder (8041) to rotate. The outer cylinder (8041) drives the first pipe magnetic seat (806) and one of the magnetically attracted metal pipes thereon to rotate.
