Technical Field

[0001] The invention relates to the technical field of laser marking equipment, in particular to laser marking equipment for producing and processing hardware pipe fittings. Background Art

[0002] Laser marking is a marking method that uses high-energy-density lasers to partially irradiate the workpiece, causing the surface material to vaporize or undergo a chemical reaction that changes color, thereby leaving a permanent mark. Laser marking can produce various texts, symbols, and patterns, and the character size can range from millimeters to microns, which is of special significance for product anti-counterfeiting. Laser marking equipment is widely used in the marking of graphics and text in various fields such as electronics, hardware, aviation devices, and auto parts. With the continuous development of science and technology and the rapid progress of society, the application of hardware pipe fittings is also increasing. When producing hardware pipe fittings, it is necessary to print specific marks on the hardware pipe fittings, and then laser marking equipment is needed for laser marking.

[0003] At present, when marking hardware pipe fittings, it is easy to be affected by the extended length of the pipe fittings, causing the ends of the pipe fittings to tilt downward. At the same time, vibrations are inevitable with the operation of the equipment, making the structure unstable, resulting in inaccurate laser marking and affecting the normal progress of the work.

[0005] A frame, the frame having a supporting frame body, and a supporting ceiling is fixedly installed on the top of the frame;

[0006] A processing mechanism, which is used to perform laser marking on hardware pipe fittings, and is installed in the middle of the top of the supporting ceiling;

[0007] Wherein, the processing mechanism comprises a cylinder, which is fixedly installed at the middle of the top of the supporting ceiling, a laser marker is fixedly installed at the output end of the cylinder, a roller is rotatably installed at the side of the top of the laser marker, a U-shaped guide groove is slidably installed on the outer cylindrical surface of the top of the roller, a guide rod is slidably installed at the side of the inner wall of the U-shaped guide groove, a fan-shaped block is fixedly installed at the bottom end of the guide rod, a sliding frame is fixedly installed at the top of the U-shaped guide groove and close to the guide rod, and the top of the sliding frame is slidably installed between the top of the supporting ceiling, and the laser marker can be driven to move upward and downward by the contraction and extension of the output end of the cylinder, so that the height is adjusted by the up and down movement of the laser marker, and the distance between the laser marker and the hardware pipe fittings is adjusted, which helps the laser marker to laser mark the hardware pipe fittings;

[0008] The laser marking equipment for the production and processing of hardware pipe fittings also includes:

[0009] A stabilizing component, which is used to support the ends of the hardware pipe fittings, and the stabilizing component is installed on the side of the top of the rack;

[0010] Among them, the stabilizing component includes a guide rail, the bottom of the guide rail is fixedly installed on the top of the frame, an I-shaped slider and a connecting slider are slidably installed inside the guide rail, an elastic strip is fixedly installed between the connecting slider and the I-shaped slider, a conical block is fixedly installed on the top of the I-shaped slider through a supporting leg, the fan-shaped clamping block is clamped on the top of the conical block, and a strip tooth is fixedly installed on the conical surface of the outer side of the conical block. By sleeveing ​​the end of the hardware pipe fitting on the surface of the conical block, the end of the hardware pipe fitting can be supported by the conical block, so that when the hardware pipe fitting moves and extends toward the discharge port close to the conical block, the end of the hardware pipe fitting is not easy to tilt downward.

[0011] The side of the strip teeth away from the conical block is an inclined surface, so that the outer side of the strip teeth is a pointed tip, which can reduce the contact area between the strip teeth and the inner hole of the end of the hardware pipe fittings. In addition, the strip teeth are evenly distributed on the conical surface outside the conical block, so that the strip teeth are evenly distributed on the conical surface outside the conical block and will not rotate randomly, making the laser marking more accurate.

[0012] As the hardware pipe fittings continue to move toward the discharge port in the direction close to the conical block, and the I-shaped slider and the connecting slider are slidably connected, the elastic strip is compressed, which helps with subsequent resetting.

[0013] Preferably, there are two cylinders, and the two cylinders are symmetrically installed along the laser marker, and the outer side of the roller is in contact with the inner wall of the U-shaped guide slot. As the laser marker moves up and down, the guide rod and the U-shaped guide slot are slidably installed, and the guiding effect of the guide rod can make the overall movement of the laser marker more stable and less prone to shaking.

[0014] Preferably, the connecting sliders are evenly distributed inside the guide rail, and the elastic strips and the connecting sliders are staggered.

[0015] Preferably, the conical block is installed directly above the frame, and the bar teeth are evenly distributed on the conical surface of the outer side of the conical block. The side of the bar teeth away from the conical block is an inclined surface, and a fan-shaped clamp is clamped on the top of the conical block. As the conical block is pushed to the right, the conical block applies a driving force to the fan-shaped clamp and the guide rod toward the discharge port in the direction close to the conical block. Under the rolling support of the roller and the sliding connection of the sliding frame, the U-shaped guide groove can slide to the right, connecting the structures together, so that when the conical block moves, the structures support each other, making the overall operation of the mechanism more stable.

[0017] At the same time, the output end of the servo motor can be rotated to drive the feed barrel to rotate, so that the hardware pipe fittings can be transported, so that the hardware pipe fittings move toward the discharge port close to the cone block, and the right-angle lever will roll with the movement of the hardware pipe fittings. The anti-slip sleeve can increase the friction force, making it difficult for the hardware pipe fittings to slip during movement, thereby ensuring smooth material transportation.

[0018] Preferably, the servo motor and the feeding cylinder are installed at the same height, the anti-slip sleeve is made of rubber, and the pressure roller is installed directly above the feeding cylinder.

[0019] Preferably, the cleaning mechanism comprises a zigzag frame, the bottom of which is fixedly mounted on the top of the frame, a connecting ring is rotatably mounted on the top of the zigzag frame, a brush is fixedly mounted on the circular surface of the inner cavity of the connecting ring, and force-bearing teeth and wedge-shaped push blocks are respectively fixedly mounted on two symmetrical end faces of the connecting ring, the force-bearing teeth are meshingly connected with the right-angle lever, and a wiping assembly is installed on the side of the outer side of the zigzag frame and close to the wedge-shaped push block. When the feed barrel rotates, the right-angle lever is driven to rotate together, and combined with the meshing connection between the force-bearing teeth and the right-angle lever, the force-bearing teeth are subjected to the pulling force, and the zigzag frame is used to rotationally support the connecting ring, so that the brush is driven to rotate in a circle, thereby brushing the surface of the hardware pipe fittings passing through the center of the connecting ring, timely cleaning up the debris attached to the hardware pipe fittings, and fully connecting the structure together.

[0020] Preferably, the brushes are evenly distributed on the circular surface of the inner cavity of the connecting ring, and the positions of the force-bearing teeth correspond to the positions of the wedge-shaped push blocks.

[0021] Preferably, the wiping assembly comprises a square guide post, the square guide post is fixedly mounted on the side of the outer side of the zigzag frame, a zigzag connecting rod is slidably mounted in the middle of the outer side of the square guide post, a fan-shaped plate is hinged at the middle of the top of the zigzag connecting rod, and an arc-shaped wiping strip is fixedly mounted on the bottom end of the fan-shaped plate, and an elastic pressing sheet is fixedly mounted between the top of the fan-shaped plate and the top of the zigzag connecting rod, and a ball head rod is fixedly mounted on the outer side of the zigzag connecting rod and close to the wedge-shaped push block, and a return spring is fixedly mounted between the bottom of the zigzag connecting rod and the outer side of the zigzag frame and close to the square guide post. With the rotation of the connecting ring, the wedge push block can be driven to rotate, and the wedge push block is used to contact the end of the ball head rod, and under the continuous rotation of the wedge push block, the wedge push block applies a pushing force to the ball head rod, and under the sliding support of the square guide post, the zigzag connecting rod drives the fan plate and the arc-shaped wiping strip to move together to the side close to the conical block, and the return spring is stretched;

[0022] As the wedge-shaped push block separates from the end of the ball head rod, the pushing force on the ball head rod disappears, and under the pulling force of the reset spring, the zigzag connecting rod drives the fan plate and the arc-shaped wiping strip to move in the opposite direction for reset. Then, the arc-shaped wiping strip moves back and forth to wipe the surface of the hardware pipe fittings, clean the remaining dust, and reduce the influence of debris on laser marking.

[0023] Preferably, there are two ball head rods, and the two ball head rods are symmetrically installed along the fan-shaped plate, and the square guide column passes through the middle of the return spring.

[0024] The present invention provides a laser marking device for the production and processing of hardware pipe fittings. It has the following beneficial effects:

[0025] 1. The laser marking equipment for the production and processing of hardware pipe fittings can drive the laser marker to move up and down by using the contraction and extension of the cylinder output end, so as to adjust the height and the distance between the laser marker and the hardware pipe fittings by moving the laser marker up and down, thereby helping the laser marker to mark the hardware pipe fittings.

[0026] 2. The laser marking equipment for the production and processing of the hardware pipe fittings can make use of the sliding installation between the guide rod and the U-shaped guide slot as the laser marker moves up and down. The guiding effect of the guide rod can make the overall movement of the laser marker more stable and less prone to shaking.

[0027] 3. The laser marking equipment for the production and processing of the hardware pipe fittings uses the end of the hardware pipe fitting to be sleeved on the surface of the conical block, so that the end of the hardware pipe fitting can be supported by the conical block, so that when the hardware pipe fitting moves and extends toward the discharge port in the direction close to the conical block, the end of the hardware pipe fitting is not easy to tilt downward.

[0028] Fourth, the laser marking equipment for the production and processing of the hardware pipe fittings uses the side of the strip teeth away from the conical block as an inclined surface, so that the outer side of the strip teeth is a pointed end, which can reduce the contact area between the strip teeth and the inner hole at the end of the hardware pipe fittings, and under the action of the top pressure, the strip teeth are evenly distributed on the conical surface outside the conical block and will not rotate at will, making the laser marking more accurate. As the hardware pipe fittings continue to move toward the discharge port in the direction close to the conical block, and under the sliding connection of the I-shaped slider and the connecting slider, the elastic strip is compressed, which helps with subsequent resetting.

[0029] 5. The laser marking equipment for the production and processing of hardware pipe fittings, as the conical block is pushed to the right, causes the conical block to apply a driving force to the fan-shaped block and the guide rod at the discharge port in the direction close to the conical block, and under the rolling support of the roller and the sliding connection of the sliding frame, the U-shaped guide groove can slide to the right, connecting the structures together, so that when the conical block moves, the structures support each other, making the overall operation of the mechanism more stable.

[0030] 6. The laser marking equipment for the production and processing of the hardware pipe fittings, under the elastic tension of the curved elastic sheet, does not elastically press the hardware pipe fittings between the pressure roller and the feed barrel, and is not prone to deviation. At the same time, the output end of the servo motor is rotated to drive the feed barrel to rotate, so that the hardware pipe fittings can be transported, so that the hardware pipe fittings move toward the discharge port in the direction close to the conical block, and the right-angle lever will roll with the movement of the hardware pipe fittings, and the anti-slip sleeve can be used to increase the friction, so that the hardware pipe fittings are not prone to slipping during movement, so that the material can be transported smoothly.

[0031] 7. The laser marking equipment for the production and processing of hardware pipe fittings uses a feed tube to drive the right-angle lever to rotate, and combines the meshing connection between the force-bearing teeth and the right-angle lever, so that after the force-bearing teeth are subjected to the pulling force, the zigzag frame is used to support the connecting ring for rotation, so that the brush is driven to rotate in a circle, thereby brushing the surface of the hardware pipe fittings passing through the center of the connecting ring, and timely cleaning the debris attached to the hardware pipe fittings.

[0032] 8. The laser marking equipment for the production and processing of the hardware pipe fittings uses a wedge-shaped push block and a ball head rod to apply a driving force, so that the zigzag connecting rod drives the fan-shaped plate and the arc-shaped wiping strip to move toward the side close to the conical block. As the wedge-shaped push block is separated from the end of the ball head rod, the driving force on the ball head rod disappears, and under the tension of the reset spring, the arc-shaped wiping strip moves in the opposite direction for reset. Then, the arc-shaped wiping strip moves back and forth to wipe the surface of the hardware pipe fittings, clean up the remaining dust, and reduce the influence of debris on the laser marking.

[0045] A frame 1, wherein the frame 1 has a supporting frame body, and a supporting ceiling 2 is fixedly installed on the top of the frame 1;

[0046] A processing mechanism 3, which is used to perform laser marking on hardware pipe fittings, and is installed in the middle of the top of the supporting ceiling 2;

[0047] The processing mechanism 3 includes a cylinder 31, which is fixedly installed in the middle of the top of the supporting ceiling 2. A laser marker 32 is fixedly installed at the output end of the cylinder 31. A roller 33 is rotatably installed at the side of the top of the laser marker 32. A U-shaped guide groove 37 is slidably installed on the outer cylindrical surface of the top of the roller 33. A guide rod 34 is slidably installed at the side of the inner wall of the U-shaped guide groove 37. A fan-shaped block 35 is fixedly installed at the bottom end of the guide rod 34. A sliding frame 36 is fixedly installed at the top of the U-shaped guide groove 37 and close to the guide rod 34. The top of the sliding frame 36 is slidably installed between the top of the supporting ceiling 2. The staff turns on the cylinder 31 to work, and the laser marker 32 can be driven to move upward and downward by the contraction and extension of the output end of the cylinder 31, so that the height is adjusted by the up and down movement of the laser marker 32, and the distance between the laser marker 32 and the hardware pipe fittings is adjusted, which helps the laser marker 32 to laser mark the hardware pipe fittings.

[0048] There are two cylinders 31, and the two cylinders 31 are symmetrically installed along the laser marker 32. The outer side of the roller 33 fits with the inner wall of the U-shaped guide groove 37. As the laser marker 32 moves up and down, the guide rod 34 and the U-shaped guide groove 37 are slidably installed, and the guiding effect of the guide rod 34 can make the overall movement of the laser marker 32 more stable.

[0049] The second embodiment, as Figure 1-Figure 5 As shown, based on the first embodiment:

[0050] The laser marking equipment for the production and processing of hardware pipe fittings also includes:

[0051] A stabilizing component 4, which is used to support the ends of the hardware pipe fittings, and is installed on the side of the top of the frame 1;

[0052] Among them, the stabilizing component 4 includes a guide rail 41, the bottom of the guide rail 41 is fixedly installed on the top of the frame 1, and an I-shaped slider 42 and a connecting slider 43 are slidably installed inside the guide rail 41, and an elastic strip 44 is fixedly installed between the connecting slider 43 and the I-shaped slider 42. A conical block 45 is fixedly installed on the top of the I-shaped slider 42 through a supporting leg, and a fan-shaped clamping block 35 is clamped on the top of the conical block 45. A strip tooth 46 is fixedly installed on the conical surface of the outer side of the conical block 45. By using the end of the hardware pipe fitting to be sleeved on the surface of the conical block 45, the end of the hardware pipe fitting can be supported by the conical block 45, so that when the hardware pipe fitting moves and extends toward the discharge port close to the conical block 45, the end of the hardware pipe fitting is not easy to tilt downward.

[0053] By making the side of the strip teeth 46 away from the conical block 45 into an inclined surface, the outer side of the strip teeth 46 is made into a pointed point, which can reduce the contact area between the strip teeth 46 and the inner hole of the end of the hardware pipe fitting. In addition, the strip teeth 46 are evenly distributed on the conical surface outside the conical block 45, so that the strip teeth 46 are evenly distributed on the conical surface outside the conical block 45 and will not rotate at will, making the laser marking more accurate.

[0054] The connecting sliders 43 are evenly distributed inside the guide rails 41, and the elastic strips 44 and the connecting sliders 43 are staggered. As the hardware pipe fittings continue to move toward the discharge port in the direction close to the conical block 45, and under the sliding connection between the I-shaped slider 42 and the connecting slider 43, the elastic strips 44 are compressed, which helps with subsequent resetting.

[0055] The conical block 45 is installed directly above the frame 1, and the bar teeth 46 are evenly distributed on the conical surface of the outer side of the conical block 45. The side of the bar teeth 46 away from the conical block 45 is an inclined surface. The fan-shaped clamping block 35 is clamped on the top of the conical block 45. As the conical block 45 is pushed to the right, the conical block 45 applies a driving force to the fan-shaped clamping block 35 and the guide rod 34 toward the discharge port in the direction close to the conical block 45. Under the rolling support of the roller 33 and the sliding connection of the sliding frame 36, the U-shaped guide groove 37 can slide to the right, connecting the structures together, so that when the conical block 45 moves, the structures support each other, making the overall operation of the mechanism more stable.

[0062] As the wedge-shaped push block 65 is separated from the end of the ball head rod 666, the pushing force on the ball head rod 666 disappears, and under the pulling force of the reset spring 667, the zigzag connecting rod 662 drives the fan plate 663 and the arc-shaped wiping strip 664 to move in the opposite direction for reset. Then, the arc-shaped wiping strip 664 moves back and forth to wipe the surface of the hardware pipe fittings, wipe off the remaining dust, and reduce the influence of debris on laser marking.

[0065] At this time, the staff starts the servo motor 54 to work, and the output end of the servo motor 54 is rotated to drive the feeding tube 52 to rotate, so that the hardware pipe fittings can be transported, so that the hardware pipe fittings move toward the discharge port close to the conical block 45, and the right-angle lever 55 rolls with the movement of the hardware pipe fittings, and the anti-slip sleeve 53 can be used to increase the friction force, so that the hardware pipe fittings are not easy to slip during movement, so that the material can be transported smoothly;

[0066] At the same time, when the feeding cylinder 52 rotates, the right-angle lever 55 is driven to rotate together, and the meshing connection between the force-bearing tooth 64 and the right-angle lever 55 is combined, so that after the force-bearing tooth 64 is subjected to the pulling force, the connecting ring 62 is supported and rotated by the zigzag frame 61, so that the brush 63 is driven to rotate in a circle, thereby brushing the surface of the hardware pipe passing through the center of the connecting ring 62, and with the rotation of the connecting ring 62, the wedge-shaped push block 65 can be driven to rotate, and the wedge-shaped push block 65 is used to contact the end of the ball head rod 666, and under the continuous rotation of the wedge-shaped push block 65, the wedge-shaped push block 65 applies a pushing force to the ball head rod 666, and under the sliding support of the square guide column 661, the zigzag connecting rod 662 drives the fan plate 663 and the arc-shaped wiping strip 664 to move to the side close to the conical block 45, and the return spring 667 is stretched;

[0067] As the wedge-shaped push block 65 is separated from the end of the ball rod 666, the pushing force on the ball rod 666 disappears, and under the pulling force of the reset spring 667, the zigzag connecting rod 662 drives the fan plate 663 and the arc-shaped wiping strip 664 to move in the opposite direction to reset, and then the arc-shaped wiping strip 664 moves back and forth to wipe the surface of the hardware pipe fittings, so that the surface of the hardware pipe fittings remains clean;

[0068] The staff starts the cylinder 31 to work, and uses the extension of the output end of the cylinder 31 to drive the laser marker 32 to move downward, adjust the distance between the laser marker 32 and the hardware pipe fittings, and use the laser marker 32 to laser mark the hardware pipe fittings;

[0069] Moreover, by sleeve-mounting the end of the hardware pipe fitting on the surface of the conical block 45, the end of the hardware pipe fitting can be supported by the conical block 45, so that when the hardware pipe fitting moves and stretches toward the discharge port in the direction close to the conical block 45, the end of the hardware pipe fitting is not likely to tilt downward;

[0070] The side of the strip teeth 46 away from the conical block 45 is an inclined surface, so that the outer side of the strip teeth 46 is a pointed end, which can reduce the contact area between the strip teeth 46 and the inner hole of the end of the hardware pipe fitting. In addition, the strip teeth 46 are evenly distributed on the conical surface outside the conical block 45, so that the strip teeth 46 are evenly distributed on the conical surface outside the conical block 45 and will not rotate randomly, making the laser marking more accurate.

[0071] The sector block 35 is clamped on the top of the conical block 45. As the conical block 45 is pushed to the right, the conical block 45 applies a driving force to the sector block 35 and the guide rod 34 toward the discharge port of the conical block 45. Under the rolling support of the roller 33 and the sliding connection of the sliding frame 36, the U-shaped guide groove 37 can slide to the right, connecting the structures together. When the conical block 45 moves, the structures support each other, making the overall operation of the mechanism more stable.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
