Description

Technical Field

[0001] This utility model belongs to the field of laser marking machine feeding technology, specifically relating to a buffer-type feeding mechanism that matches a laser marking machine. Background Technology

[0002] Laser marking machines use a laser beam 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, thus engraving intricate patterns, trademarks, and text.

[0003] In existing laser marking machines, the loading and unloading process commonly uses suction cups to transfer products. When the suction cup releases the marked product, the product experiences a downward impact due to its own weight and the force of release, directly colliding with the unloading platform. This can easily lead to surface damage, positioning misalignment, and even affect the accuracy of subsequent processing. Furthermore, the existing unloading structure lacks efficient conveying components, hindering rapid transfer of marked products and reducing overall production efficiency. Additionally, the lack of a targeted anti-deviation structure during unloading makes products prone to deviation and tipping during transport, further impacting production continuity.

[0004] Therefore, we propose a buffer-type feeding mechanism that is compatible with laser marking machines. Utility Model Content

[0005] The purpose of this invention is to provide a buffer-type unloading mechanism for laser marking machines, addressing the common practice in the loading and unloading processes of existing laser marking machines, where suction cups are used to transfer products. When the suction cup releases the marked product, the product experiences a downward impact due to its own weight and the force of release, directly colliding with the unloading platform. This can easily lead to surface damage, positioning misalignment, and even affect subsequent processing accuracy. Furthermore, existing unloading structures lack efficient conveying components, hindering rapid transfer of marked products and reducing overall production efficiency. The lack of a targeted anti-deviation structure during unloading also makes products prone to deviation and tipping during transport, further impacting production continuity.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a buffer-type feeding mechanism for matching a laser marking machine, including a mounting base plate, wherein mounting bolts are provided at the four corners of the mounting base plate;

[0007] A buffer substrate is disposed on one side of a mounting substrate. A sliding block is fixedly connected to the side of the buffer substrate. A spring is fixedly connected between the end of the sliding block and the mounting substrate. A damper is fixedly connected between the side of the mounting substrate and the side of the buffer substrate.

[0008] The feeding conveyor is rotatably mounted on the side of the buffer base plate. A cylinder is fixedly connected to the side of the buffer base plate. A hinge seat is fixedly connected to the piston rod end of the cylinder. A hinge arm is hinged to the hinge seat. The other end of the hinge arm is hinged to the feeding conveyor. The feeding conveyor is equipped with a conveying unit for the marked products and an anti-deviation unit for preventing the marked products conveyed by the conveying unit from deviating.

[0009] The conveying unit includes a motor fixedly connected to the side of the unloading conveyor seat, two conveying rollers rotatably installed inside the unloading conveyor seat, and a conveyor belt connected between the two conveying rollers. The output shaft of the motor is fixedly connected to one of the conveying rollers.

[0010] The anti-deviation unit includes a second motor fixedly connected to the side of the feeding conveyor seat, a bidirectional screw rotatably connected to the feeding conveyor seat, a threaded seat threaded to the two threaded surfaces of the bidirectional screw, a connecting rod fixedly connected to the side of the threaded seat, and an anti-deviation plate fixed to the other end of the connecting rod. The output shaft of the second motor is fixedly connected to the bidirectional screw, the connecting rod slides through the feeding conveyor seat, and the anti-deviation plate is located above the conveyor belt.

[0011] The above solution, through the coordinated use of springs and dampers, effectively absorbs the impact force during product unloading when the marked product is placed on the suction cup, preventing direct collision between the product and the supporting structure, protecting the product surface quality and structural stability. The conveying unit achieves rapid product transfer via motor, replacing traditional manual unloading, significantly improving production efficiency and adapting to the needs of automated production lines. By setting up an anti-deviation unit, the spacing of the anti-deviation plates can be flexibly adjusted via a bidirectional screw to adapt to products of different widths. The support roller design reduces friction damage, ensuring accurate and non-deviation-prone product conveying. The cylinder-driven unloading conveyor seat allows for angle adjustment, adapting to different models of laser marking machines and unloading scenarios, demonstrating strong versatility.

[0012] In the above scheme, it should be noted that motor one, motor two and cylinder are all electrically connected to an external power source.

[0013] In a preferred embodiment, a guide rod is fixedly connected to the side of the mounting base plate, the spring is sleeved on the outside of the guide rod, and the sliding block is slidably connected to the outer surface of the guide rod.

[0014] By adopting the above scheme, the guide rod provides precise sliding guidance for the sliding block, preventing the sliding block from shifting or tilting during the buffering process. At the same time, it limits the deformation direction of the spring, preventing the spring from twisting due to uneven force, and ensuring the stability and service life of the buffering mechanism.

[0015] In a preferred embodiment, a plurality of guide bars are fixedly connected to the side of the mounting base, and the side of the hinge seat is provided with guide grooves for sliding engagement of the guide bars.

[0016] By adopting the above scheme, the guide bar and the guide groove form a sliding fit, which limits the movement direction of the articulated seat, avoids lateral deviation when the cylinder drives the articulated seat, ensures that the movement trajectory of the articulated seat and the articulated arm is accurate, and thus ensures that the angle adjustment of the feeding conveyor seat is stable and reliable.

[0017] In a preferred embodiment, limit rings are fixedly connected to the outer surfaces of both ends of the conveyor roller, and the limit rings are fitted and arranged on the side of the conveyor belt.

[0018] By adopting the above solution, the limiting ring fits tightly against the side of the conveyor belt, which can effectively limit the axial displacement of the conveyor belt, prevent the conveyor belt from running off-track during long-term operation, and ensure the conveying accuracy and stability of the conveying unit.

[0019] In a preferred embodiment, the inner wall of the feeding conveyor is fixedly connected with several limiting rods, and the threaded seat is slidably connected to the outer surface of the several limiting rods.

[0020] Using the above scheme, the limiting rod provides sliding support and guidance for the threaded seat, preventing the threaded seat from rotating on its own when it rotates with the bidirectional screw, ensuring that the threaded seat only moves along the axial direction of the bidirectional screw, thereby ensuring the synchronization of the adjustment of the two anti-deviation plates and the accuracy of the spacing.

[0021] In one preferred embodiment, the side of the anti-deviation plate is rotatably connected to several support rollers, and the support rollers on two anti-deviation plates are arranged opposite to each other.

[0022] Using the above solution, the support roller can rotate around its own axis. When the product comes into contact with the anti-deviation plate, the sliding friction is converted into rolling friction, which greatly reduces the friction between the product and the anti-deviation plate, avoids scratches on the product surface due to friction, and ensures smooth product conveying without affecting conveying efficiency.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] The buffered feeding mechanism of this matching laser marking machine uses springs and dampers to work together to effectively absorb the impact force when the marked product is placed by the suction cup, avoiding direct collision between the product and the supporting structure, protecting the product surface quality and the stability of the mechanism. The conveying unit realizes rapid product transfer through a motor, replacing traditional manual feeding, greatly improving production efficiency, and adapting to the needs of automated production lines.

[0025] The buffer-type feeding mechanism of this laser marking machine is equipped with an anti-deviation unit. The spacing between the anti-deviation plates can be flexibly adjusted by a bidirectional screw to adapt to products of different widths. The support roller design reduces friction damage and ensures accurate and non-deviation-oriented product delivery. The cylinder-driven feeding conveyor seat can achieve angle adjustment, adapting to different models of laser marking machines and feeding scenarios, making it highly versatile.

[0031] Please see Figure 1-4 This utility model provides a buffer-type unloading mechanism for matching laser marking machines, including a mounting base plate 1. Mounting bolts 2 are provided at the four corners of the mounting base plate 1. The mounting bolts 2 facilitate the quick fixing of the mechanism to the unloading station of the laser marking machine. Disassembly is convenient and it can be adapted to the installation requirements of different models of laser marking machines, thus improving the versatility of the mechanism.

[0032] A buffer base plate 3 is disposed on one side of the mounting base plate 1. A sliding block 4 is fixedly connected to the side of the buffer base plate 3. A spring 5 is fixedly connected between the end of the sliding block 4 and the mounting base plate 1. A damper 6 is fixedly connected between the side of the mounting base plate 1 and the side of the buffer base plate 3. The sliding block 4 provides sliding support for the buffer base plate 3. The spring 5 absorbs the impact force when the product is unloaded by using elastic deformation. The damper 6 can slow down the rebound speed of the spring 5. The two work together to form a buffer and shock absorption system to prevent the product from directly impacting the load-bearing structure and protect the product surface and the stability of the mechanism.

[0033] The feeding conveyor seat 7 is rotatably mounted on the side of the buffer base plate 3. A cylinder 8 is fixedly connected to the side of the buffer base plate 3. A hinge seat 9 is fixedly connected to the piston rod end of the cylinder 8. A hinge arm 10 is hinged to the hinge seat 9. The other end of the hinge arm 10 is hinged to the feeding conveyor seat 7. The cylinder 8, as a driving component, can push the hinge seat 9 to move by extending and retracting the piston rod. The hinge seat 9 drives the hinge arm 10 to rotate, thereby driving the feeding conveyor seat 7 to rotate around the hinge point with the buffer base plate 3, so as to realize the adjustment of the tilt angle of the feeding conveyor seat 7 and adapt to the needs of different heights and different feeding directions.

[0034] The unloading conveyor seat 7 is equipped with a conveying unit for the marked products and an anti-deviation unit for preventing the marked products conveyed by the conveying unit from deviating.

[0035] The conveying unit includes a motor 11 fixedly connected to the side of the unloading conveying seat 7, two conveying rollers 12 rotatably installed in the unloading conveying seat 7, and a conveyor belt 13 connected between the two conveying rollers 12. The output shaft of the motor 11 is fixedly connected to one of the conveying rollers 12.

[0036] The anti-deviation unit includes a second motor 14 fixedly connected to the side of the feeding conveyor seat 7, a bidirectional screw 15 rotatably connected inside the feeding conveyor seat 7, a threaded seat 16 threadedly connected to the two threaded surfaces of the bidirectional screw 15, a connecting rod 17 fixedly connected to the side of the threaded seat 16, and an anti-deviation plate 18 fixedly connected to the other end of the connecting rod 17. The output shaft of the second motor 14 is fixedly connected to the bidirectional screw 15, the connecting rod 17 slides through the feeding conveyor seat 7, and the anti-deviation plate 18 is located above the conveyor belt 13.

[0037] By using spring 5 and damper 6 in synergy, the impact force of the product during unloading can be effectively absorbed when the marked product is placed on the suction cup, avoiding direct collision between the product and the supporting structure, protecting the product surface quality and the stability of the mechanism. The conveying unit realizes rapid product transfer through motor, replacing traditional manual unloading, greatly improving production efficiency and adapting to the needs of automated production lines. By setting up an anti-deviation unit, the spacing of the anti-deviation plate 18 can be flexibly adjusted through the bidirectional screw 15 to adapt to products of different widths. The support roller 23 is designed to reduce friction damage and ensure accurate and non-deviation-prone product conveying. The cylinder 8 drives the unloading conveyor seat 7 to realize angle adjustment, adapting to different models of laser marking machines and unloading scenarios, with strong versatility.

[0038] A guide rod 19 is fixedly connected to the side of the mounting base plate 1. A spring 5 is sleeved on the outside of the guide rod 19. A sliding block 4 is slidably connected to the outer surface of the guide rod 19. The guide rod 19 provides precise sliding guidance for the sliding block 4, preventing the sliding block 4 from shifting or tilting during the buffering process. At the same time, it limits the deformation direction of the spring 5, preventing the spring 5 from twisting due to uneven force, and ensuring the stability and service life of the buffering mechanism.

[0039] Several guide bars 20 are fixedly connected to the side of the mounting base 1. The side of the hinge seat 9 is provided with a guide groove for the guide bars 20 to slide and engage. The guide bars 20 and the guide groove form a sliding engagement, which limits the movement direction of the hinge seat 9 and prevents lateral deviation when the cylinder 8 drives the hinge seat 9. This ensures that the movement trajectory of the hinge seat 9 driving the hinge arm 10 is accurate, thereby ensuring that the angle adjustment of the unloading conveyor seat 7 is stable and reliable.

[0040] Limiting rings 21 are fixedly connected to the outer surfaces of both ends of the conveyor roller 12. The limiting rings 21 are closely attached to the side of the conveyor belt 13. The limiting rings 21 are tightly attached to the side of the conveyor belt 13, which can effectively limit the axial displacement of the conveyor belt 13, prevent the conveyor belt 13 from running off-center during long-term operation, and ensure the conveying accuracy and stability of the conveying unit.

[0041] The inner wall of the feeding conveyor seat 7 is fixedly connected with several limiting rods 22. The threaded seat 16 is slidably connected to the outer surface of the limiting rods 22. The limiting rods 22 provide sliding support and guidance for the threaded seat 16, preventing the threaded seat 16 from rotating when it rotates with the bidirectional screw 15, ensuring that the threaded seat 16 only moves along the axial direction of the bidirectional screw 15, thereby ensuring the synchronization of the adjustment of the two anti-deviation plates 18 and the accuracy of the spacing.

[0042] Several support rollers 23 are rotatably connected to the side of the anti-deviation plate 18. The support rollers 23 on the two anti-deviation plates 18 are arranged opposite each other. The support rollers 23 can rotate around their own axis. When the product comes into contact with the anti-deviation plate 18, the sliding friction is converted into rolling friction, which greatly reduces the friction between the product and the anti-deviation plate 18, avoids scratches on the product surface due to friction, and ensures smooth product conveying without affecting the conveying efficiency.

[0043] When using

[0044] Installation: Fix the mounting base plate 1 onto the laser marking machine using mounting bolts 2.

[0045] Adjustment of feeding conveyor angle and anti-deviation plate 18:

[0046] Material feeding conveyor angle adjustment: The hinge seat 9 is driven by the cylinder 8 to slide along the guide bar 20. The hinge seat 9 drives the hinge arm 10 to rotate, thereby adjusting the tilt angle of the material feeding conveyor 7 to adapt to the material feeding angle requirements.

[0047] Adjustment of anti-deviation plate 18: Start motor 2 14, motor 2 14 drives bidirectional screw 15 to rotate, threaded seat 16 slides along limit rod 22, and drives two anti-deviation plates 18 to move in opposite directions or in opposite directions through connecting rod 17, and adjusts to the spacing that matches the product width;

[0048] Feeding buffer: After the laser marking machine completes the product marking, the suction cup releases the product, and the product falls onto the conveyor belt 13 of the feeding conveyor seat 7. At this time, the impact force of the product is transmitted to the buffer base plate 3. The buffer base plate 3 slides along the guide rod 19 through the sliding block 4. The spring 5 is compressed to absorb the impact force, and the damper 6 slows down the rebound speed of the spring 5 to achieve smooth buffering and avoid product damage.

[0049] Conveying Anti-deviation: Start motor 11, which drives conveyor roller 12 to rotate. Conveyor roller 12 carries the product to the subsequent work station through conveyor belt 13. Limiting rings 21 at both ends of conveyor roller 12 prevent conveyor belt 13 from deviating. During the conveying process, anti-deviation plate 18 limits the product. Support roller 23 rotates with the product to reduce friction between the product and anti-deviation plate 18, avoid product deviation or surface scratches, and achieve efficient and accurate feeding and conveying.
