Description

Technical Field

[0001] This utility model relates to the field of marking machine technology, and in particular to an online laser marking machine. Background Technology

[0002] Laser marking machines (laser engraving machines) use lasers to create permanent marks on the surfaces of various materials. The marking effect occurs by evaporating the surface material to expose the deeper material, thus engraving intricate patterns, trademarks, and text. Laser marking machines are widely used in electronic components, integrated circuits (ICs), electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, eyeglasses and watches, jewelry, automotive parts, plastic buttons, building materials, PVC pipes, and more.

[0003] Among existing patents, Chinese patent document with application number 201911116724.1 discloses a laser engraving machine and its method of use. The first transmission device of this patent document includes a transmission track and a transmission drive motor. The transmission track includes two transmission belts arranged vertically. Each transmission belt has a first driving wheel and a first driven wheel at both ends. The first driving wheel is connected to the transmission drive motor, and the transmission drive motor drives the first driving wheel to rotate through gears. The clamping device includes a clamping plate, a moving plate, and a clamping drive cylinder. The clamping drive cylinder moves by driving the plate. The plate moves, causing the clamping plate to move as well, thereby clamping and fixing the engraving plate. The clamping plate includes an upper clamping plate and a lower clamping plate, which are respectively disposed between the upper and lower transmission belts. The moving plate includes an upper moving plate and a lower moving plate, which are fixedly connected to the upper clamping plate and the lower clamping plate respectively by connecting rods. The clamping drive cylinder includes an upper clamping drive cylinder and a lower clamping drive cylinder, which drive the upper moving plate and the lower moving plate to move up and down respectively, thereby clamping and fixing the engraving plate between the upper and lower transmission belts. The first transmission device in this patent document requires two transmission belts to transport the plate. When clamping the plate, an upper clamping drive cylinder and a lower clamping drive cylinder are needed to drive the upper moving plate and the lower moving plate to move respectively to clamp the plate between the two transmission belts. Although this structural design can achieve the flipping of the plate to laser mark the front and back sides, it is too complex and increases the cost for plates that only need single-sided laser marking. In addition, the upper clamping drive cylinder and the lower clamping drive cylinder need to drive the upper moving plate and the lower moving plate to move respectively to clamp the plate.

[0004] Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide an online laser marking machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An online laser marking machine includes a machine base, a mounting base mounted on the table of the machine base, a fixed conveying mechanism mounted on the mounting base, a movable conveying mechanism parallel to and movably mounted on the mounting base, a spacing adjustment mechanism for adjusting the distance between the fixed conveying mechanism and the movable conveying mechanism, a guide rail base located on one side of the mounting base, a longitudinal movement drive mechanism located on the other side of the mounting base, a transverse movement drive mechanism suspended above the mounting base, a lifting drive mechanism mounted on the moving end of the transverse movement drive mechanism, a laser marking mechanism mounted on the lifting end of the lifting drive mechanism, and a smoke extractor mounted on the lifting end of the lifting drive mechanism.

The lifting drive module is used to drive the lifting clamping plate closer to or away from the fixed clamping plate. The base of the fixed conveyor mechanism is mounted on a mounting base, and the base of the movable conveyor mechanism is connected to the adjusting end of the spacing adjustment mechanism.

[0008] Furthermore, the lifting drive module includes a lifting cylinder installed on the outside of the base and a lifting plate connected to the piston rod of the lifting cylinder.

[0009] Furthermore, the online laser marking machine also includes a second transverse drive mechanism, a second guide rail seat located below the mounting base, a second longitudinal drive mechanism arranged parallel to the second guide rail seat, a second lifting drive mechanism installed at the moving end of the second transverse drive mechanism, a second laser marking mechanism installed at the lifting end of the second lifting drive mechanism, and a second smoke extractor / dust collector installed at the lifting end of the second lifting drive mechanism. One end of the second transverse drive mechanism is slidably connected to the second guide rail seat, and the other end of the second transverse drive mechanism is connected to the moving end of the second longitudinal drive mechanism. The first laser marking mechanism and the second laser marking mechanism are arranged vertically opposite each other. The second laser marking mechanism is located inside the machine base. Both the second guide rail seat and the second longitudinal drive mechanism are installed inside the machine base. The table surface of the machine base has laser marking holes.

[0010] Furthermore, the laser marking mechanism two includes a housing installed at the lifting end of the lifting drive mechanism two, a beam combiner installed at an angle inside the housing, a ring light source installed in the housing and located above the beam combiner, a laser installed in the housing and located below the beam combiner, and a camera located on one side of the beam combiner. A through hole is opened on the top surface of the housing, and an anti-fog and anti-dust lens is installed at the through hole. The ring light source is arranged around the through hole. The laser emitted by the laser can penetrate the beam combiner, and the visible light is reflected by the beam combiner to the camera end of the camera.

[0011] Furthermore, there is a wiping gap between the ring light source and the anti-fog and dustproof mirror, and a wiping block is movably arranged in the wiping gap. The housing is equipped with a wiping driver for driving the wiping block to move back and forth. The wiping block is slidably connected to the top surface of the anti-fog and dustproof mirror.

[0012] Furthermore, an adjustment plate is installed on one side of the enclosure, and the camera is mounted on the adjustment plate.

[0013] Furthermore, the housing has a first lock hole, and a first locking fastener is detachably connected to the first lock hole.

[0014] Furthermore, the camera has a second locking hole, which is detachably connected to a second locking fastener. The other end of the adjustment plate has a focal length adjustment groove that communicates with the second locking hole. The second locking fastener is used to lock the adjustment plate onto the camera.

[0015] Furthermore, the inductive material blocking module includes a sensor mounted on the base, a material blocking cylinder mounted on the base, and a material blocking block mounted on the piston rod of the material blocking cylinder.

[0016] Furthermore, multiple protrusions are spaced apart at the ends of the clamping plates of the fixed clamping plates, and the multiple protrusions are located above the upper belt layer of the conveyor belt.

[0017] The beneficial effects of this utility model are as follows: In practical applications, an external device transports a workpiece onto the conveyor belts of both the fixed and movable conveyor mechanisms. These conveyor belts support both sides of the workpiece (e.g., a circuit board). A rotary driver drives the conveyor belts to rotate, and the workpiece is transported through the coordinated operation of the fixed and movable conveyor belts. When the sensing blocking module detects the workpiece, it indicates that the workpiece has reached the laser marking position. The sensing blocking module then blocks the workpiece and sends a signal to the rotary driver and lifting drive module, causing the rotary driver to stop driving the conveyor belt. The lifting drive module then drives the lifting clamp to rise, which in turn lifts the upper layer of the conveyor belt along with the workpiece until the conveyor belt... The upper layer of the conveyor belt cooperates with the fixed clamping plate to hold the plate and position it. Then, under the coordinated action of the longitudinal drive mechanism, the transverse drive mechanism, and the lifting drive mechanism, the laser marking mechanism is driven to adjust its position. The laser marking mechanism performs laser marking on the plate. During the laser marking process, the smoke and / or dust collector removes the smoke and / or dust generated during laser marking to prevent smoke and / or dust from interfering with the precise laser marking. After the laser marking of the plate is completed, the lifting drive module drives the lifting clamping plate to descend and reset, allowing the conveyor belt to elastically recover and release its grip on the plate. The rotary driver drives the conveyor belt to rotate to output the laser-marked plate to the external device. During the conveyor belt's transport of the plate, the lifting clamping plate supports the upper layer of the conveyor belt. In addition, the spacing adjustment mechanism adjusts the spacing between the fixed conveyor mechanism and the movable conveyor mechanism according to the different sizes of plates to meet the transport needs of plates of different sizes. This utility model has a simple structure and low cost. It can realize online laser marking of plates with high laser marking efficiency. The lifting clamp not only supports the upper layer of the conveyor belt, but also drives the upper layer of the conveyor belt to lift and lower to clamp or loosen the plates. When clamping the plates, the conveyor belt is clamped between the plates and the lifting clamp. The elasticity of the conveyor belt plays a buffering and protective role for the plates, reducing the chance of damaging the plates. Attached Figure Description

[0027] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0028] Example 1.

[0029] like Figures 1 to 4As shown, the present invention provides an online laser marking machine, which includes a machine base 1, a mounting base 2 mounted on the table surface of the machine base 1, a fixed conveying mechanism 3 mounted on the mounting base 2, a movable conveying mechanism 4 parallel to the fixed conveying mechanism 3 and movably mounted on the mounting base 2, a spacing adjustment mechanism 5 mounted on the mounting base 2 and used to adjust the spacing between the fixed conveying mechanism 3 and the movable conveying mechanism 4, a guide rail seat 6 mounted on the table surface of the machine base 1 and located on one side of the mounting base 2, and another guide rail seat 6 mounted on the table surface of the machine base 1 and located on the other side of the mounting base 2. The system includes a longitudinal drive mechanism 7 on one side, a transverse drive mechanism 8 suspended above the mounting base 2, a lifting drive mechanism 9 mounted on the moving end of the transverse drive mechanism 8, a laser marking mechanism 10 mounted on the lifting end of the lifting drive mechanism 9, and a smoke extractor 11 mounted on the lifting end of the lifting drive mechanism 9. One end of the transverse drive mechanism 8 is connected to the moving end of the longitudinal drive mechanism 7, and the other end of the transverse drive mechanism 8 is slidably connected to the guide rail base 6. It also includes a movable conveying mechanism 4 and a fixed conveying mechanism. Each of the three components includes a base 12, two pulleys 13 rotatably connected to both ends of the base 12, a conveyor belt 14 wound around the two pulleys 13, a rotary drive 15 mounted on the base 12 for driving the conveyor belt 14, a fixed clamping plate 16 mounted on the top surface of the base 12, a lifting clamping plate 17 lifted and lowered inside the base 12 and located within the annular space of the conveyor belt 14, a lifting drive module 18 mounted on the outside of the base 12, and a sensing and stopping module 19 mounted on the base 12. The clamping mechanism of the fixed clamping plate 16... The plate end extends above the upper belt layer of the conveyor belt 14. The fixed clamping plate 16, the upper belt layer of the conveyor belt 14, and the lifting clamping plate 17 are arranged sequentially from top to bottom. The lifting drive module 18 is used to drive the lifting clamping plate 17 to move closer to or away from the fixed clamping plate 16. The base 12 of the fixed conveying mechanism 3 is mounted on the mounting base 2. The base 12 of the movable conveying mechanism 4 is connected to the adjustment end of the spacing adjustment mechanism 5. The sensing stop module 19 is electrically connected to the rotary driver 15 and the lifting drive module 18 respectively. Specifically, the conveyor belt 14 is an elastic belt.

[0030] In practical applications, an external device transports a board to the conveyor belt 14 of the fixed conveyor mechanism 3 and the conveyor belt 14 of the movable conveyor mechanism 4. The conveyor belts 14 of the fixed conveyor mechanism 3 and the movable conveyor mechanism 4 support the two sides of the board (e.g., a circuit board). The rotary driver 15 drives the conveyor belt 14 to rotate. The board is transported under the coordinated action of the conveyor belts 14 of the fixed conveyor mechanism 3 and the movable conveyor mechanism 4. When the sensing blocking module 19 senses the board, it indicates that the board has been transported to the laser marking position. The sensing blocking module 19 blocks the board and sends a signal to the rotary driver 15 and the lifting drive module 18, causing the rotary driver 15 to stop driving the conveyor belt 14. The lifting drive module 18 drives the lifting clamp 17 to rise. The rising lifting clamp 17 will drive the upper layer of the conveyor belt 14, along with the board, to rise until the conveyor belt... The upper layer of conveyor belt 14 cooperates with the fixed clamping plate 16 to clamp the plate and achieve positioning of the plate. Then, under the coordinated cooperation of the longitudinal drive mechanism 7, the transverse drive mechanism 8 and the lifting drive mechanism 9, the laser marking mechanism 10 is driven to adjust its position. The laser marking mechanism 10 performs laser marking on the plate. During the laser marking process, the smoke extractor 11 removes the smoke and / or dust generated during laser marking to prevent the smoke and / or dust from interfering with the laser marking mechanism 10's accurate laser marking. After completing the laser marking on the plate, the lifting drive module 18 drives the lifting clamping plate 17 to descend and reset, so that the conveyor belt 14 elastically recovers and releases the clamping of the plate. The rotation driver 15 drives the conveyor belt 14 to rotate to output the laser-marked plate to the external device 2. During the conveying of the plate by the conveyor belt 14, the lifting clamping plate 17 supports the upper layer of the conveyor belt 14. In addition, the spacing adjustment mechanism 5 adjusts the spacing between the fixed conveying mechanism 3 and the movable conveying mechanism 4 according to the different sizes of the plates, so as to meet the needs of conveying plates of different sizes. This utility model has a simple structure and low cost, and can realize online laser marking of plates with high laser marking efficiency. The lifting clamping plate 17 can not only support the upper layer of the conveyor belt 14, but also drive the upper layer of the conveyor belt 14 to lift and lower to clamp or loosen the plates. When clamping the plates, the conveyor belt 14 is clamped between the plates and the lifting clamping plate 17. The elasticity of the conveyor belt 14 plays a buffering and protective role for the plates, reducing the probability of damaging the plates.

[0031] In this embodiment, the lifting drive module 18 includes a lifting cylinder 20 mounted on the outside of the base 12 and a lifting plate 21 connected to the piston rod of the lifting cylinder 20. The lifting plate 21 is provided with a connecting block 22, and the base 12 has a lifting hole 23. The connecting block 22 passes through the lifting hole 23 and is fixedly connected to the lifting clamping plate 17. Specifically, the connecting block 22 can move up and down within the lifting hole 23.

[0032] In practical applications, after the workpiece moves to the marking position, the lifting cylinder 20 drives the lifting plate 21, along with the connecting block 22 and the lifting clamping plate 17, to rise. The rising lifting clamping plate 17 causes the upper layer of the conveyor belt 14 to move upward, resulting in a recoverable elastic deformation of the upper layer of the conveyor belt 14 until the conveyor belt 14 engages with the fixed clamping plate 16 to clamp the workpiece. After laser marking is completed, the lifting cylinder 20 drives the lifting plate 21, along with the connecting block 22 and the lifting clamping plate 17, to descend and reset, causing the upper layer of the conveyor belt 14 to regain its elasticity, and the conveyor belt 14 can then transport the workpiece normally.

[0033] In this embodiment, the sensing blocking module 19 includes a sensor 41 mounted on the base 12, a blocking cylinder 42 mounted on the base 12, and a blocking block 43 mounted on the piston rod of the blocking cylinder 42. The blocking cylinder 42 is used to drive the blocking block 43 to rise and fall. The sensor 41 is electrically connected to the rotary driver 15 and the lifting drive module 18 respectively.

[0034] In practical applications, the conveyor belt 14 of the fixed conveyor mechanism 3 and the conveyor belt 14 of the movable conveyor mechanism 4 convey the plate. When the sensor 41 senses the front edge of the plate, the blocking cylinder 42 drives the blocking block 43 to descend, so that the blocking block 43 blocks the front edge of the plate. The sensor 41 feeds back a signal to the rotary driver 15 and the lifting drive module 18, so that the rotary driver 15 stops driving the conveyor belt 14, and the lifting drive module 18 drives the lifting clamping plate 17 to rise until the conveyor belt 14 cooperates with the fixed clamping plate 16 to clamp the plate.

[0035] In this embodiment, multiple protrusions 44 are spaced apart at the clamping end of the fixing clamp 16, and the multiple protrusions 44 are located above the upper belt layer of the conveyor belt 14. This structural design clamps the plate with the upper belt layer of the conveyor belt 14 through the multiple protrusions 44, reducing the contact area between the fixing clamp 16 and the plate, and can avoid the processing position of the plate, making it less likely to damage the plate.

[0036] Example 2.

[0037] like Figures 5 to 7As shown, the difference between this embodiment and Embodiment 1 is that the online laser marking machine also includes a second transverse drive mechanism 24, a second guide rail seat 25 located below the mounting base 2, a second longitudinal drive mechanism 26 arranged parallel to the second guide rail seat 25, a second lifting drive mechanism 27 installed at the moving end of the second transverse drive mechanism 24, a second laser marking mechanism 45 installed at the lifting end of the second lifting drive mechanism 27, and a second smoke extractor 28 installed at the lifting end of the second lifting drive mechanism 27. One end of the second transverse drive mechanism 24 is slidably connected to the second guide rail seat 25, and the other end of the second transverse drive mechanism 24 is connected to the moving end of the second longitudinal drive mechanism 26. The first laser marking mechanism 10 and the second laser marking mechanism 45 are arranged vertically opposite each other. The second laser marking mechanism 45 is located inside the machine base 1. The second guide rail seat 25 and the second longitudinal drive mechanism 26 are both installed inside the machine base 1. The table surface and the base 12 of the machine base 1 are both provided with laser marking holes 29.

[0038] In practical applications, when laser marking is required on both sides of a board, while laser marking mechanism 10 performs laser marking on the front of the board, the horizontal movement drive mechanism 24, the vertical movement drive mechanism 26, and the lifting drive mechanism 27 work together to drive laser marking mechanism 45 to move and adjust its position. The laser emitted by laser marking mechanism 45 passes through the laser marking hole 29 and performs laser marking on the back of the board. During the laser marking process, the smoke and dust collector 28 removes the smoke and / or dust generated during laser marking. This structural design allows for laser marking on both sides of a board without requiring the board to be flipped, greatly improving laser marking efficiency. Furthermore, laser marking mechanism 10 and laser marking mechanism 45 can work simultaneously or independently, offering flexibility and convenience.

[0039] In this embodiment, the laser marking mechanism 2 45 includes a housing 30 mounted on the lifting end of the lifting drive mechanism 27, a beam combiner 31 tilted inside the housing 30, a ring light source 32 mounted on the housing 30 and located above the beam combiner 31, a laser 33 mounted on the housing 30 and located below the beam combiner 31, and a camera 34 located on one side of the beam combiner 31. The top surface of the housing 30 has a through hole, and an anti-fog and dustproof lens 35 is installed at the through hole. The ring light source 32 is arranged around the through hole. The laser emitted by the laser 33 can penetrate the beam combiner 31, and visible light is reflected by the beam combiner 31 to the camera end of the camera 34. The beam combiner 31 can transmit laser light and reflect visible light.

[0040] In practical applications, the ring light source 32 emits light and illuminates the area on the board to be laser-marked. The visible light reflected by the board is reflected by the beam combiner 31 to the camera end of the camera 34. The camera 34 can visually locate the area on the board to be laser-marked and can also record the laser marking process in real time. In addition, the laser emitted by the laser 33 passes through the beam combiner 31 and performs laser marking on the board.

[0041] Since the laser marking mechanism 2 45 is located below the plate, in order to prevent dust and other foreign objects generated during the laser marking process from falling into the housing 30 and / or onto the beam combiner 31, the anti-fog and dustproof mirror 35 protects the beam combiner 31. When dust or other foreign objects fall onto the anti-fog and dustproof mirror 35, it is easy to clean by simply wiping the anti-fog and dustproof mirror 35.

[0042] In this embodiment, a wiping gap 36 is provided between the ring light source 32 and the anti-fog and dustproof mirror 35. A wiping block 46 is movably disposed within the wiping gap 36. The housing 30 is equipped with a wiping driver 37 for driving the wiping block 46 to reciprocate. The wiping block 46 is slidably connected to the top surface of the anti-fog and dustproof mirror 35. Specifically, the wiping driver 37 can be a cylinder, and the wiping block 46 can be made of cloth or sponge.

[0043] In practical applications, when it is necessary to clean the anti-fog and dustproof mirror 35, the wiping driver 37 drives the wiping block 46 to move back and forth on the top surface of the anti-fog and dustproof mirror 35, so that the wiping block 46 wipes the anti-fog and dustproof mirror 35 back and forth to clean the anti-fog and dustproof mirror 35.

[0044] In this embodiment, an adjustment plate 38 is installed on one side of the housing 30, and the camera 34 is mounted on the adjustment plate 38. This structural design facilitates the disassembly, assembly, and maintenance of the housing 30 and the camera 34.

[0045] In this embodiment, the housing 30 has a first locking hole, and a first locking fastener is detachably connected to the first locking hole. One end of the adjusting plate 38 has a height adjusting groove 39 communicating with the first locking hole. The first locking fastener is used to lock the adjusting plate 38 onto the housing 30. Specifically, the first locking hole is a screw hole, and the first locking fastener is a bolt.

[0046] In practical applications, when it is necessary to adjust the position of the camera 34's shooting plate, the first locking fastener is loosened, allowing the adjustment plate 38 to move up and down relative to the housing 30 along the height adjustment groove 39. After the adjustment is completed, the first locking fastener is tightened, locking the adjustment plate 38 onto the housing 30. Since the beam combiner 31 is tilted at 45°, when the height position of the camera 34 changes, the position of the camera 34's shooting plate will also change accordingly, thus achieving adjustable visual position of the camera 34.

[0047] In this embodiment, the camera 34 has a second locking hole, and a second locking fastener is detachably connected to the second locking hole. The other end of the adjustment plate 38 has a focus adjustment groove 40 communicating with the second locking hole. The second locking fastener is used to lock the adjustment plate 38 onto the camera 34. Specifically, the second locking hole is a screw hole, and the second locking fastener is a bolt.

[0048] In practical applications, when it is necessary to adjust the focal length of the camera 34 shooting the plate, the second locking fastener is loosened so that the camera 34 can move horizontally relative to the adjustment plate 38 along the focal length adjustment groove 40. After the adjustment is completed, the second locking fastener is tightened so that the second locking fastener locks the adjustment plate 38 and the camera 34 together.

[0049] Preferably, the laser marking mechanism 10 can adopt the structure of the laser marking mechanism 45, which will not be described in detail here.

[0050] The remaining structures of this embodiment are the same as those of Embodiment 1, and will not be described again here.

[0051] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
