A fully automated laser marking machine and method

Abstract

This invention belongs to the field of laser marking technology and discloses a fully automated laser marking machine and method, including a fixed frame and a conveying assembly. The conveying assembly is disposed inside the fixed frame, and a motor for driving the conveying assembly to rotate is installed outside the fixed frame. This invention conveys cylindrical workpieces by rotating the conveying frame.

During the movement, the middle of the smoke collection tube is under negative pressure. At this time, the second one-way valve is open, and the first one-way valve is closed. The smoke generated by the workpiece marking inside the fixed frame enters the interior of the smoke collection tube through the second one-way valve, realizing the collection of the smoke generated by the workpiece marking. Simultaneously, the fixed frame effectively suppresses the diffusion of the smoke.

Description

Technical Field

[0001] This invention belongs to the field of laser marking technology, specifically a fully automated laser marking machine and method. Background Technology

[0002] Fully automatic laser marking machines are highly efficient marking devices. They utilize the interaction between a laser beam and the surface of an object. The high energy density of the laser beam causes the surface material to evaporate instantly or change color, thus forming the desired mark. The working principle of a laser marking machine involves components such as a laser, modulator, module, and inkjet printer. The laser source generated by the modulator is reflected onto the inkjet printer. The inkjet printer precisely controls the laser point and its spacing, moving to scan the laser point and complete the laser marking. Driven by a drive, the inkjet printer moves horizontally and vertically, repeatedly scanning, and through the accumulated scanning effect, forms a clear marking pattern, creating appropriate marks on objects and packaging. Currently, laser marking machines generate harmful fumes when the laser source contacts the workpiece during the marking process on cylindrical workpieces. Existing laser marking equipment lacks fume treatment equipment, causing the fumes to diffuse into the workshop. The only way to purify the fumes is to clean the workshop air, but it is difficult to suppress the diffusion of fumes during the marking process. Continuous marking of workpieces results in the continuous generation of fumes, leading to the presence of harmful fumes in the workshop, which will affect the health of operators in the long term. Therefore, a fully automated laser marking machine and method are proposed. Summary of the Invention

[0003] To address the problems mentioned in the background section, this invention provides a fully automated laser marking machine and method, which solves the problem that existing laser marking equipment is unable to suppress the diffusion of fumes, resulting in harmful fumes in the workshop that will affect the health of operators in the long term.

[0009] A limiting component is disposed on the conveying component for limiting the position of the workpiece;

[0010] A purification component, which is mounted on the outside of the mounting frame;

[0011] The conveying assembly includes a conveying frame disposed inside the fixed frame;

[0012] The purification component includes a smoke storage tube fixed to the outside of the fixed frame, with protective shells fixed to both ends of the smoke storage tube.

The protrusion on the inner wall of the gear is movably engaged with the inside of the spiral groove.

[0014] The connecting rod has a horizontal groove on its outside, and the smoke storage tube slides in the horizontal groove, allowing the connecting rod to move laterally.

[0015] The gear engages with the helical groove, causing the movable plate to move from the middle of the smoke storage tube to the outer end;

[0016] The smoke storage pipe is connected to the interior of the fixed frame through a second one-way valve, and the smoke storage pipe is connected to the flue gas purification equipment through a first one-way valve.

[0017] Preferably, the conveying assembly further includes grooves arranged in a ring array on the outside of the conveying frame, the inner wall of the grooves having a first limiting groove, one end of the grooves having a second limiting groove, and a threaded rod fixedly mounted on the side of the conveying frame.

[0018] Preferably, the storage assembly includes a storage box fixed to the top of the fixed frame, a limit plate is movably arranged inside the storage box, and a vertical groove is opened at one end of the storage box;

[0019] The bottom of the storage box is connected to the interior of the fixing frame, and the bottom of the storage box is vertically aligned with the groove.

[0020] Preferably, the support assembly includes a connecting frame sleeved on the side of the conveyor frame, the connecting frame being mounted on the threaded rod by a first nut, the first nut being movably sleeved with the connecting frame.

[0021] Preferably, the support assembly further includes a support frame installed in a ring array outside the connecting frame, a limit block is fixedly installed at the bottom of the support frame, and a third limit groove is opened at one end of the support frame;

[0022] The limiting block engages inside the first limiting groove, and one end of the support frame engages inside the second limiting groove.

[0023] Preferably, pads are symmetrically installed on the periphery of the support frame;

[0024] The support frame is located inside the groove, and the pad is located between the support frame and the groove.

[0025] Preferably, the limiting component includes a stabilizing frame sleeved on the outside of the threaded rod, and the stabilizing frame is installed on the threaded rod by a second nut;

[0026] The outer ring array of the stabilizer is fixed with connectors, and one end of the connector is fixed with an abutment block.

[0027] Preferably, the stabilizer is sleeved on the outside of the threaded rod, and the stabilizer is driven to move by the second nut cooperating with the threaded rod. The connector is engaged inside the third limiting groove, and the abutment block is located inside the support frame.

[0028] Preferably, the limiting component further includes a docking ring sleeved on the side of the stabilizer, and an abutment plate is fixedly mounted on the outside of the docking ring;

[0029] The stabilizing frame moves along the threaded rod, and the abutment plate engages in the vertical groove, pushing the limiting plate to move along the inside of the storage box to the other end, shortening the length inside the storage box.

[0030] This invention also provides a method for using a fully automated laser marking machine, comprising the following steps:

[0031] S1. Select a support frame of appropriate size according to the outer diameter of the cylindrical workpiece. Push the connecting frame onto the side of the conveyor frame by cooperating with the first nut and the threaded rod. The support frame is located inside the groove, the limiting block is engaged in the first limiting groove, and one end of the support frame is engaged in the second limiting groove.

[0032] S2. The stabilizer is sleeved on the outside of the threaded rod, the connector is engaged in the inside of the third limiting groove, and the abutment block is located inside the support frame. At the same time, the abutment plate is engaged in the inside of the vertical groove to limit the abutment plate. The abutment plate pushes the limiting plate to shorten the distance between the limiting plate and the storage box. At this time, the side of the limiting plate and the abutment block are on the same plane.

[0033] S3. The workpiece falls into the support frame through the storage box. The cylindrical workpiece is transported by the rotating conveyor frame. The automated laser marking machine marks the workpiece. During the rotation of the conveyor frame, the rack drives the gear to rotate. Since the gear is engaged inside the spiral groove and the two ends of the smoke storage tube slide in the transverse groove outside the connecting rod, the rotation of the gear and the spiral groove drive the connecting rod and the movable plate, so that the middle of the smoke storage tube moves outward and compresses the return spring. During the movement, the middle of the smoke storage tube is in a negative pressure state. The smoke generated by the workpiece marking in the fixed frame enters the interior of the smoke storage tube through the second one-way valve.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0035] This invention uses a rotating conveyor to transport cylindrical workpieces. An automated laser marking machine marks the workpieces, generating fumes. During the rotation of the conveyor, a rack drives a gear. The gear engages with the spiral groove, and the two ends of the fixed frame slide in the transverse groove outside the connecting rod. The gear rotation, in conjunction with the spiral groove, drives the connecting rod and the movable plate, causing the middle of the fumes collection tube to move outward and compress the return spring. During this movement, the middle of the fumes collection tube is under negative pressure. At this time, the second one-way valve is open, and the first one-way valve is closed. The fumes generated by the workpiece marking inside the fixed frame enter the fumes collection tube through the second one-way valve, thus collecting the fumes generated by the workpiece marking. At the same time, the fixed frame effectively suppresses the diffusion of the fumes.

[0036] This invention uses a connecting frame sleeved on the outside of the threaded rod. A first nut, in cooperation with the threaded rod, pushes the connecting frame to the side of the conveyor frame. Simultaneously, a support frame is located inside a groove, a limiting block engages inside a first limiting groove, and a pad is located between the groove and the support frame to improve the stability of the support frame. One end of the support frame engages inside a second limiting groove to prevent the support frame from rotating. A motor drives the conveyor frame and support assembly to rotate, keeping the support frame and storage box vertical. The workpiece can then fall into the interior of the support frame, enabling inkjet printing processing of workpieces with different outer diameters.

[0037] In this invention, the second nut, in conjunction with the threaded rod, drives the stabilizing frame to move along the threaded rod. During this process, the connecting piece engages inside the third limiting groove, while the abutment block is located inside the support frame. Simultaneously, the abutment plate engages inside the vertical groove, limiting its position. The abutment plate pushes the limiting plate to shorten the distance between the limiting plate and the storage box. At this time, the sides of the limiting plate and the abutment block remain on the same plane. The distance between the storage box and the limiting plate meets the length of the workpiece, allowing the workpiece to be placed in the storage box and its position limited. The workpiece then falls into the support frame through the storage box, and the abutment block limits the workpiece within the support frame, preventing misalignment of the workpiece's inkjet printing.

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] like Figures 1 to 11 As shown, the present invention provides a fully automated laser marking machine, including a fixed frame 1, and further comprising:

[0052] The conveying assembly 4 is disposed inside the fixed frame 1, and a motor for driving the conveying assembly 4 to rotate is installed on the outside of the fixed frame 1.

[0053] Automated laser marking machine 2 is installed outside the fixed frame 1 and is used to mark the workpieces conveyed by the conveying assembly 4.

[0054] Material storage assembly 7 is fixedly mounted on the top of the fixing frame 1;

[0055] Support component 5 is mounted on conveying component 4;

[0056] Limiting component 6 is disposed on conveying component 4 and is used to limit the workpiece.

[0057] Purification component 3 is installed on the outside of the mounting bracket 1;

[0058] The conveying assembly 4 includes a conveying frame 41 disposed inside the fixed frame 1;

[0059] The purification component 3 includes a smoke storage pipe 31 fixed to the outside of the fixed frame 1. Protective shells 35 are fixed to both ends of the smoke storage pipe 31. Gears 36 are movably installed inside the protective shells 35. The outer ring array of the conveying frame 41 is provided with racks 30 that mesh with the gears 36.

[0060] A movable plate 39 is movably fitted inside the smoke storage tube 31. A return spring 34 is provided between the movable plate 39 and the smoke storage tube 31. A connecting rod 37 is fixedly installed on the side of the movable plate 39. A spiral groove 33 is opened on the outside of the connecting rod 37. The protrusion on the inner wall of the gear 36 is movably engaged inside the spiral groove 33.

[0061] A transverse groove is provided on the outside of the connecting rod 37, and the smoke storage pipe 31 slides in the transverse groove, so that the connecting rod 37 can move laterally.

[0062] The gear 36 engages with the spiral groove 33, causing the movable plate 39 to move from the middle of the smoke storage pipe 31 to the outer end;

[0063] The smoke storage pipe 31 is connected to the interior of the fixed frame 1 through the second one-way valve 38, and the smoke storage pipe 31 is connected to the flue gas purification equipment through the first one-way valve 32.

[0064] The cylindrical workpiece is conveyed by the rotating conveyor frame 41. The automated laser marking machine 2 marks the workpiece, which generates smoke. During the rotation of the conveyor frame 41, the rack 30 drives the gear 36 to rotate. Since the gear 36 is engaged inside the spiral groove 33 and the two ends of the fixed frame 1 slide in the transverse groove outside the connecting rod 37, the rotation of the gear 36 and the spiral groove 33 drive the connecting rod 37 and the movable plate 39 to move the middle of the smoke storage tube 31 outward and compress the return spring 34. During the movement, the middle of the smoke storage tube 31 is in a negative pressure state. At this time, the second one-way valve 38 is in the open state and the first one-way valve 32 is in the closed state. The smoke generated by the workpiece marking in the fixed frame 1 enters the interior of the smoke storage tube 31 through the second one-way valve 38, realizing the collection of the smoke generated by the workpiece marking. At the same time, the fixed frame 1 can effectively suppress the diffusion of smoke.

[0065] The motor drives the conveyor frame 41 to rotate continuously, and the rack 30 will disengage from the gear 36. At this time, the return spring 34 resets and drives the gear 36 to rotate in the opposite direction, pushing the connecting rod 37 and the movable plate 39 to move in opposite directions, so that the two movable plates 39 move synchronously towards the middle. The pressure in the smoke storage pipe 31 increases, the second one-way valve 38 is in the closed state, and the first one-way valve 32 is in the open state, so that the flue gas in the smoke storage pipe 31 can be injected into the flue gas purification equipment.

[0066] like Figures 2-4 As shown, the conveying assembly 4 also includes grooves 42 arranged in an annular array outside the conveying frame 41. The inner wall of the grooves 42 is provided with a first limiting groove 43, and one end of the grooves 42 is provided with a second limiting groove 44. A threaded rod 45 is fixedly installed on the side of the conveying frame 41.

[0067] The storage assembly 7 includes a storage box 71 fixed to the top of the fixed frame 1. A limit plate 72 is movably installed inside the storage box 71, and a vertical groove 73 is provided at one end of the storage box 71.

[0068] The bottom of the storage box 71 is connected to the interior of the fixing frame 1, and the bottom of the storage box 71 is vertical to the groove 42.

[0069] When a cylindrical workpiece is placed inside a storage box 71 and the groove 42 is kept vertical, the workpiece in the storage box 71 falls into the groove 42. The motor drives the conveyor frame 41 and the cylindrical workpiece to rotate for inkjet printing. As the workpiece rotates with the conveyor frame 41, it contacts the inner wall of the fixed frame 1 and is limited by the inner wall of the fixed frame 1, so that the workpiece is always located inside the groove 42 and the workpiece is prevented from shifting.

[0070] like Figures 4-7 As shown, the support assembly 5 includes a connecting frame 51 sleeved on the side of the conveyor frame 41. The connecting frame 51 is installed on the threaded rod 45 by a first nut 55. The first nut 55 is movably sleeved with the connecting frame 51.

[0071] The support assembly 5 also includes a support frame 53 mounted in a ring array outside the connecting frame 51. A limit block 56 is fixedly installed at the bottom of the support frame 53, and a third limit groove 54 is provided at one end of the support frame 53.

[0072] The limiting block 56 is engaged inside the first limiting groove 43, and one end of the support frame 53 is engaged inside the second limiting groove 44;

[0073] The support frame 53 is symmetrically equipped with pads 52 on its outer periphery;

[0074] The support frame 53 is located inside the groove 42, and the pad 52 is located between the support frame 53 and the groove 42.

[0075] Based on the outer diameter of the cylindrical workpiece, a support frame 53 of appropriate size is selected. The connecting frame 51 is sleeved on the outside of the threaded rod 45. The first nut 55 cooperates with the threaded rod 45 to push the connecting frame 51 to the side of the conveyor frame 41. At the same time, the support frame 53 is located inside the groove 42. The limiting block 56 is engaged inside the first limiting groove 43. The pad 52 is located between the groove 42 and the support frame 53 to improve the stability of the support frame 53. One end of the support frame 53 is engaged inside the second limiting groove 44 to prevent the support frame 53 from rotating. The motor drives the conveyor frame 41 and the support assembly 5 to rotate. The support frame 53 and the storage box 71 remain vertical, and the workpiece can fall into the inside of the support frame 53. This enables the inkjet printing of workpieces with different outer diameters. The workpiece can be rotated to ensure that the outer periphery of the workpiece is always in contact with the inner wall of the fixed frame 1.

[0076] like Figures 4-7 As shown, the limiting component 6 includes a stabilizing frame 61 sleeved on the outside of the threaded rod 45, and the stabilizing frame 61 is installed on the threaded rod 45 by a second nut 64;

[0077] The outer ring array of the stabilizer 61 is fixedly equipped with a connector 65, and one end of the connector 65 is fixedly equipped with an abutment block 66;

[0078] The stabilizer 61 is sleeved on the outside of the threaded rod 45. The second nut 64 cooperates with the threaded rod 45 to push the stabilizer 61 to move. The connector 65 is engaged inside the third limiting groove 54. The abutment block 66 is located inside the support frame 53.

[0079] The limiting component 6 also includes a docking ring 62 sleeved on the side of the stabilizer 61, and an abutment plate 63 is fixedly installed on the outside of the docking ring 62;

[0080] The stabilizer 61 moves along the threaded rod 45, and the contact plate 63 engages in the vertical groove 73, pushing the limiting plate 72 to move along the storage box 71 to the other end, shortening the length of the storage box 71.

[0081] As the stabilizer 61 is sleeved on the outside of the threaded rod 45, the second nut 64 cooperates with the threaded rod 45 to push the stabilizer 61 to move along the threaded rod 45. During this process, the connector 65 is engaged inside the third limiting groove 54, while the abutment block 66 is located inside the support frame 53. At the same time, the abutment plate 63 is engaged inside the vertical groove 73 to limit the abutment plate 63. The abutment plate 63 pushes the limiting plate 72 to shorten the distance between the limiting plate 72 and the storage box 71. At this time, the side of the limiting plate 72 and the abutment block 66 are on the same plane. The distance between the storage box 71 and the limiting plate 72 meets the length of the workpiece, so the workpiece can be placed in the storage box 71 and the workpiece is limited.

[0082] The workpiece falls into the support frame 53 through the storage box 71. The conveyor frame 41 drives the workpiece to rotate. The contact block 66 limits the workpiece in the support frame 53 to prevent the workpiece coding from deviating.

[0083] This invention also provides a method for using a fully automated laser marking machine, comprising the following steps:

[0084] S1. Select a support frame 53 of appropriate size according to the outer diameter of the cylindrical workpiece. Push the connecting frame 51 onto the side of the conveying frame 41 by cooperating with the first nut 55 and the threaded rod 45. The support frame 53 is located inside the groove 42. The limiting block 56 is engaged inside the first limiting groove 43, and one end of the support frame 53 is engaged inside the second limiting groove 44.

[0085] S2. The stabilizer 61 is sleeved on the outside of the threaded rod 45, the connector 65 is engaged in the inside of the third limiting groove 54, and the abutment block 66 is located inside the support frame 53. At the same time, the abutment plate 63 is engaged in the inside of the vertical groove 73 to limit the abutment plate 63. The abutment plate 63 pushes the limiting plate 72 to shorten the distance between the limiting plate 72 and the storage box 71. At this time, the limiting plate 72 and the side of the abutment block 66 are on the same plane.

[0086] S3. The workpiece falls into the support frame 53 through the storage box 71. The cylindrical workpiece is transported by the rotating conveyor frame 41. The automated laser marking machine 2 marks the workpiece. During the rotation of the conveyor frame 41, the gear 36 is driven to rotate by the rack 30. Since the gear 36 is engaged inside the spiral groove 33 and the two ends of the smoke storage tube 31 slide in the transverse groove outside the connecting rod 37, the rotation of the gear 36 and the spiral groove 33 drive the connecting rod 37 and the movable plate 39, so that the middle part of the smoke storage tube 31 moves outward and compresses the return spring 34. During the movement, the middle part of the smoke storage tube 31 is in a negative pressure state. The smoke generated by the workpiece marking in the fixed frame 1 enters the interior of the smoke storage tube 31 through the second one-way valve 38.

[0087] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
