Description

Technical Field

[0001] This utility model relates to the field of marking machine technology, and in particular to a dual-platform laser marking machine. Background Technology

[0002] A laser marking machine is a device that uses a laser beam to permanently mark the surface of various materials. It uses a high-energy-density laser beam to irradiate the material surface, causing physical or chemical changes and thus forming clear patterns, text, or barcodes. Due to its high efficiency, precision, and environmental friendliness, laser marking machines are widely used in modern manufacturing. With the continuous improvement of industrial automation, traditional single-platform laser marking machines can no longer meet the increasing demands for production efficiency and personalization. Therefore, dual-platform laser marking machines have emerged. For example, Chinese patent application number 202221506143.6 discloses a dual-station laser marking machine for FPC reinforcing steel sheets, including a frame module, a platform module, a laser processing and positioning module, and a self-inspection module. The frame module includes a main frame, and the platform module includes a marble platform and a dual-station platform assembly. The platform is mounted on the main frame. The dual-station platform assembly includes a left-hand Y-axis sliding platform and a right-hand Y-axis sliding platform, both mounted on a marble platform. The laser processing and positioning module includes an optical path base, an XZ-axis moving assembly, and a laser marking and positioning assembly. The optical path base and the XZ-axis moving assembly are mounted on the marble platform, and the laser marking and positioning assembly is located at the movable end of the XZ-axis moving assembly. The self-inspection module includes an X-axis drive frame and a barcode scanning assembly, with the X-axis drive frame mounted on the marble platform. Although this patent document achieves alternating operation of the two platforms, it cannot automate loading and unloading, resulting in low automation and low production efficiency. Therefore, its shortcomings are quite obvious, and a solution is urgently needed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a dual-platform laser marking machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dual-platform laser marking machine includes a machine base, a first translation drive mechanism mounted on the table surface of the machine base, a second translation drive mechanism mounted on the table surface of the machine base and arranged parallel to the first translation drive mechanism, a first suction table mounted on the translation end of the first translation drive mechanism, a second suction table mounted on the translation end of the second translation drive mechanism, a loading / unloading moving drive device mounted at the front of the machine base, a loading / unloading mechanism mounted on the moving end of the loading / unloading moving drive device, a marking moving drive device mounted at the rear of the machine base, a laser marking device mounted on the moving end of the marking moving drive device, and other components mounted side-by-side on the machine base. The machine has a loading and unloading bin at the front of the table. The laser marking device can move above the first and second suction tables. The loading and unloading mechanism can move above the loading bin, the unloading bin, the first suction table, and the second suction table. The first and second suction tables move back and forth alternately. Both the loading and unloading bins include a base plate installed on the table surface, a first reference plate installed on one side of the top surface of the base plate, a second reference plate installed on the other side of the top surface of the base plate, and an angle iron that is movably installed on the top surface of the base plate. The angle iron is magnetically attracted to the base plate by a magnet. The base plate, the first reference plate, the second reference plate, and the angle iron form a storage cavity.

[0006] Furthermore, the bottom of the angle iron is recessed with an insert hole, into which the magnet is inserted.

[0007] Furthermore, the bottom wall of the mounting hole is recessed with a threaded hole, the middle of the magnet is recessed with a countersunk hole communicating with the threaded hole, and the bottom of the angle iron is detachably connected with a locking bolt. The screw of the locking bolt passes through the countersunk hole and is threadedly connected to the threaded hole, and the nut of the locking bolt is housed in the countersunk hole.

[0008] Furthermore, the bottom plate of the feeding hopper has a detection hole, and a bottom sensor is installed on the bottom surface of the bottom plate. The sensing end of the bottom sensor is exposed in the detection hole. The bottom sensor is used to sense whether there is material in the storage chamber.

[0009] Furthermore, a full material sensor is installed on the outer top of the first reference plate and / or the outer top of the second reference plate of the feeding hopper, with the sensing end of the full material sensor facing the top of the storage cavity.

[0010] Furthermore, the loading and unloading mechanism includes a connecting plate installed at the moving end of the loading and unloading moving drive device, a fixed frame installed on the connecting plate, several sets of fixed suction cups installed at the bottom of the fixed frame, a lifting frame that is slidably connected to the connecting rod, several sets of movable suction cups installed at the bottom of the lifting frame, and a lifting drive installed on the connecting plate for driving the lifting frame to move up and down.

[0011] Furthermore, the loading and unloading mechanism also includes a connecting rod detachably connected to the connecting plate and located between the fixed frame and the lifting frame, and a suction nozzle installed at the bottom end of the connecting rod.

[0012] Furthermore, the connecting plate has a sliding hole and a screw hole that is perpendicular to the sliding hole. A locking bolt is screwed into the screw hole, and the top of the connecting rod slides through the sliding hole. The screw of the locking bolt is used to abut against the connecting rod to lock the connecting rod onto the connecting plate.

[0013] Furthermore, the loading and unloading mechanism also includes a material retrieval and lowering position controller installed at the bottom of the lifting frame, which is electrically connected to the loading and unloading moving drive device.

[0014] Furthermore, the material handling and lowering controller includes a fixed base, a lifting rod, a sensor, a trigger rod, a contact block, and a spring. The fixed base is installed at the bottom of the lifting frame and has a receiving hole, a guide hole, and a mounting hole coaxially arranged from top to bottom. The lifting rod slides through the receiving hole, the guide hole, and the mounting hole. A limit cap is installed at the top of the lifting rod, which is located in the receiving hole and abuts against the bottom wall of the receiving hole. The side wall of the lifting rod is slidably connected to the inner wall of the guide hole. The trigger rod is installed at the top of the lifting rod, and the contact block is installed at the bottom of the lifting rod. The sensor is installed on the fixed base and located above the receiving hole. The trigger rod is used to trigger the sensor. The spring is sleeved on the outside of the lifting rod. One end of the spring is inserted into the mounting hole and abuts against the top wall of the mounting hole, and the other end of the spring abuts against the top surface of the contact block. When the spring is in the extended state, the limit cap abuts against the bottom wall of the receiving hole, and the trigger rod is located in the receiving hole.

[0015] The beneficial effects of this utility model are as follows: In practical applications, a large number of boards (such as circuit boards) are stacked in the feeding hopper. Because the first and second suction tables move alternately back and forth, when the first suction table is below the laser marking device (laser marking position), the marking movement drive device drives the laser marking device to move along a preset movement path. The laser marking device performs laser marking on the boards held by the first suction table. The second suction table is located near the feeding hopper, and the loading / unloading movement drive device drives the loading / unloading mechanism to pick up the boards from the feeding hopper onto the second suction table. The second suction table holds the boards tightly. When the second suction table is below the laser marking device (laser marking position), the marking movement drive device drives the laser marking device to move along a preset movement path. The laser marking device then performs laser marking on the boards held by the first suction table. When marking the position, the marking movement drive device drives the laser marking device to move along a preset movement path. The laser marking device performs laser marking on the board held by the second suction table. The first suction table is located at the loading position near the loading bin. The loading and unloading movement drive device drives the loading and unloading mechanism to pick up the board in the loading bin and place it on the first suction table. The first suction table holds the board tightly. As the first and second suction tables move back and forth alternately, the loading and unloading movement drive device drives the loading and unloading mechanism to pick up the laser-marked board carried by the first or second suction table and place it into the unloading bin. The unloading bin stacks and stores the laser-marked board to efficiently perform laser marking on the board. The system stores the sheet metal in a storage chamber. A first reference plate, a second reference plate, and angle irons accurately position the sheet metal, ensuring its positional accuracy and stability. This improves the positional accuracy and stability of the loading and unloading mechanism. Furthermore, the angle irons are magnetically attached to the base plate, facilitating easy assembly and disassembly, ensuring a secure connection, and allowing for easy adjustment of the angle iron's position on the base plate. This adjusts the size of the storage chamber, enabling the storage of sheet metal of different specifications. The system is highly versatile and practical. A dual-platform alternating working mode is employed, with one platform performing laser marking while the other handles loading and unloading, effectively improving machine utilization and production efficiency. The hopper size can be flexibly adjusted according to the sheet metal size, adapting to the laser marking needs of different specifications, reducing changeover time, and increasing production flexibility. Automated loading and unloading enables automatic sheet metal gripping, positioning, and placement, reducing manual intervention and improving production efficiency and safety.

[0023] 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.

[0024] like Figures 1 to 5As shown, this utility model provides a dual-platform laser marking machine, which includes a machine base 1, a first translation drive mechanism 2 mounted on the table surface of the machine base 1, a second translation drive mechanism 3 mounted on the table surface of the machine base 1 and arranged parallel to the first translation drive mechanism 2, a first suction table 4 mounted on the translation end of the first translation drive mechanism 2, a second suction table 5 mounted on the translation end of the second translation drive mechanism 3, a loading / unloading moving drive device 6 mounted at the front of the machine base 1, a loading / unloading mechanism 7 mounted at the moving end of the loading / unloading moving drive device 6, a marking moving drive device 8 mounted at the rear of the machine base 1, a laser marking device 9 mounted at the moving end of the marking moving drive device 8, and a loading bin 10 and a unloading bin 11 mounted side by side at the front of the table surface of the machine base 1. The laser marking device 9 can... The first suction platform 4 and the second suction platform 5 move above each other. The loading and unloading mechanism 7 can move above the loading bin 10, the unloading bin 11, the first suction platform 4 and the second suction platform 5. The first suction platform 4 and the second suction platform 5 move back and forth alternately. The loading bin 10 and the unloading bin 11 each include a base plate 12 installed on the table surface of the machine platform 1, a first reference plate 13 installed on one side of the top surface of the base plate 12, a second reference plate 14 installed on the other side of the top surface of the base plate 12, and an angle iron 15 movably installed on the top surface of the base plate 12. The first reference plate 13 and the second reference plate 14 form a reference angle. The angle iron 15 is magnetically attracted to the base plate 12 by a magnet 16. The base plate 12, the first reference plate 13, the second reference plate 14 and the angle iron 15 form a storage cavity. Specifically, the magnet 16 is a strong magnet 16.

[0025] In practical applications, the loading bin 10 contains a large number of boards (such as circuit boards). Because the first suction table 4 and the second suction table 5 move alternately back and forth, when the first suction table 4 is below the laser marking device 9 (the laser marking position), the marking movement drive device 8 drives the laser marking device 9 to move along a preset path. The laser marking device 9 performs laser marking on the boards held by the first suction table 4. The second suction table 5 is located near the loading bin 10 at the loading position. The loading / unloading movement drive device 6 drives the loading / unloading mechanism 7 to pick up the boards from the loading bin 10 onto the second suction table 5. The second suction table 5 holds the boards tightly. When the second suction table 5 is below the laser marking device 9 (the laser marking position), The marking movement drive device 8 drives the laser marking device 9 to move along a preset movement path. The laser marking device 9 performs laser marking on the board held by the second suction table 5. The first suction table 4 is located near the loading position of the loading bin 10. The loading and unloading movement drive device 6 drives the loading and unloading mechanism 7 to pick up the board in the loading bin 10 onto the first suction table 4. The first suction table 4 holds the board tightly. As the first suction table 4 and the second suction table 5 move back and forth alternately, the loading and unloading movement drive device 6 drives the loading and unloading mechanism 7 to pick up the laser-marked board carried by the first suction table 4 or the second suction table 5 into the unloading bin 11. The unloading bin 11 stacks and stores the laser-marked board to efficiently perform laser marking on the board. The plates are stored in the storage chamber. The first reference plate 13, the second reference plate 14, and the angle iron 15 accurately position the plates to ensure their positional accuracy and stability, thereby improving the positional accuracy and stability of the loading and unloading mechanism 7. In addition, since the angle iron 15 is magnetically attracted to the base plate 12 by the magnet 16, it is not only easy to disassemble and assemble the angle iron 15 and the base plate 12, and the connection is firm, but it is also easy to adjust the position of the angle iron 15 on the base plate 12, thereby adjusting the size of the storage chamber. This allows for the positioning and storage of plates of different specifications, making it versatile and practical. The dual-platform alternating working mode is adopted, with one platform performing laser marking while the other platform performs loading and unloading operations, effectively improving the machine's utilization rate and production efficiency. The size of the hopper can be flexibly adjusted according to the size of the plates to adapt to the laser marking requirements of different specifications of plates, reducing changeover time and improving production flexibility. Automated loading and unloading realizes automatic gripping, positioning, and placement of plates, reducing manual intervention and improving production efficiency and safety.

[0026] In this embodiment, the bottom of the angle iron 15 is recessed with an insertion hole 17, and the magnet 16 is inserted into the insertion hole 17. This structural design facilitates the assembly of the angle iron 15 and the magnet 16, making the structure of the angle iron 15 and the magnet 16 compact.

[0027] To improve the sturdiness of the assembly between the angle iron 15 and the magnet 16 and to prevent the magnet 16 from detaching from the angle iron 15 during use, in this embodiment, the bottom wall of the mounting hole 17 is recessed with a threaded hole, the middle part of the magnet 16 is recessed with a countersunk hole 18 that communicates with the threaded hole, and the bottom of the angle iron 15 is detachably connected with a locking bolt. The screw of the locking bolt passes through the countersunk hole 18 and is threadedly connected to the threaded hole, and the nut of the locking bolt is housed in the countersunk hole 18.

[0028] In this embodiment, the bottom plate 12 of the feeding hopper 10 has a detection hole 19, and a bottom sensor 20 is installed on the bottom surface of the bottom plate 12. The sensing end of the bottom sensor 20 is exposed in the detection hole 19. The bottom sensor 20 is used to sense whether there is material (such as plates) in the storage cavity. In practical applications, the bottom sensor 20 passes through the detection hole 19 to sense the material in the storage cavity of the feeding hopper 10. When the bottom sensor 20 does not sense any material, it proves that there is no material in the feeding hopper 10. The bottom sensor 20 will send a signal to the control system of the machine, causing the machine to issue an alarm to remind the operator to replenish the material in the feeding hopper 10.

[0029] In this embodiment, a full-material sensor is installed on the outer top of the first reference plate 13 and / or the outer top of the second reference plate 14 of the feeding bin 11, with the sensing end of the full-material sensor facing the top of the storage cavity. In practical applications, the full-material sensor detects the material in the storage cavity of the feeding bin 11. When the full-material sensor detects material, it indicates that the feeding bin 11 is full. The full-material sensor will send a signal to the control system of the machine, causing the machine to issue an alarm to remind the operator to remove the material from the feeding bin 11.

[0030] In this embodiment, the loading and unloading mechanism 7 includes a connecting plate 22 mounted on the moving end of the loading and unloading moving drive device 6, a fixed frame 23 mounted on the connecting plate 22, several sets of fixed suction cups 24 mounted on the bottom end of the fixed frame 23, a lifting frame 25 that is slidably connected to the connecting rod, several sets of movable suction cups 26 mounted on the bottom end of the lifting frame 25, and a lifting driver 27 mounted on the connecting plate 22 for driving the lifting frame 25 to move up and down. Specifically, the lifting driver 27 can be a cylinder.

[0031] In practical applications, the loading / unloading moving drive device 6 drives the loading / unloading mechanism 7 to move into the loading bin 10, causing the fixed suction cup group 24 and the movable suction cup group 26 to firmly grip the top layer of the board in the loading bin 10. As the loading / unloading moving drive device 6 drives the loading / unloading mechanism 7 and the board to rise, the lifting drive 27 drives the lifting frame 25 and the movable suction cup group 26 to reciprocate within a small range, causing the movable suction cup group 26 to shake the board to prevent stacking and ensure that only one board is picked up at a time. The shaking action driven by the lifting drive 27, which drives the lifting frame 25 and the movable suction cup group 26, is mainly for thinner or somewhat flexible boards. For harder and heavier boards, shaking is not necessary, and stacking is less likely to occur.

[0032] Specifically, the bottom of the mounting bracket 23 has multiple first locking holes 43 arranged in a straight line. The fixed suction cup assembly 24 is provided with a first adjusting groove 44 for communicating with the first locking holes 43. The fixed suction cup assembly 24 is locked onto the mounting bracket 23 by a first screw, which passes through the first adjusting groove 44 and is threaded into the first locking hole 43. This structural design not only allows for increasing or decreasing the number of fixed suction cup assemblies 24, but also allows for adjusting the position and angle of the fixed suction cup assemblies 24 to meet the needs of the fixed suction cup assemblies 24 in picking up plates of different sizes.

[0033] Specifically, the bottom of the lifting frame 25 has multiple second locking holes 45 arranged in a straight line. The movable suction cup assembly 26 is provided with a second adjusting groove 46 for communicating with the second locking holes 45. The movable suction cup assembly 26 is locked onto the lifting frame 25 by a second screw, which passes through the second adjusting groove 46 and is threaded into the second locking hole 45. This structural design not only allows for increasing or decreasing the number of movable suction cup assemblies 26, but also allows for adjusting the position and angle of the movable suction cup assemblies 26 to meet the needs of the movable suction cup assemblies 26 in picking up plates of different sizes.

[0034] In this embodiment, the loading and unloading mechanism 7 also includes a connecting rod 28 detachably connected to the connecting plate 22 and located between the fixed frame 23 and the lifting frame 25, and a suction nozzle 29 installed at the bottom end of the connecting rod 28. In practical applications, the connecting rod 28 can be disassembled and assembled according to actual usage needs, thereby disassembling and assembling the suction nozzle 29. When the size of the plate is relatively small, the fixed suction cup assembly 24 and the movable suction cup assembly 26 can be disassembled, and the plate can be clamped by the suction nozzle 29 alone; when the size of the plate is relatively large, the suction nozzle 29 can be disassembled, and the plate can be clamped by the fixed suction cup assembly 24 and the movable suction cup assembly 26, or the plate can be clamped by the suction nozzle 29, the fixed suction cup assembly 24, and the movable suction cup assembly 26 together. It is flexible in use and has various forms.

[0035] In this embodiment, the connecting plate 22 has a sliding hole 30 and a screw hole 31 that is perpendicularly connected to the sliding hole 30. A locking bolt is screwed into the screw hole 31. The top of the connecting rod 28 slides through the sliding hole 30. The screw of the locking bolt is used to abut against the connecting rod 28 to lock the connecting rod 28 onto the connecting plate 22. In practical applications, loosening the locking bolts allows the connecting rod 28 to move up and down relative to the connecting plate 22 along the sliding hole 30, thereby adjusting the height of the suction nozzle 29. After adjustment, tightening the locking bolts locks the connecting rod 28. When only the suction nozzle 29 is used, its height is adjusted to be lower than the fixed suction cup assembly 24 and the movable suction cup assembly 26. When the suction nozzle 29, fixed suction cup assembly 24, and movable suction cup assembly 26 need to be used simultaneously, the height of the suction nozzle 29 is adjusted to be equal to that of the fixed suction cup assembly 24 and the movable suction cup assembly 26. When only the fixed suction cup assembly 24 and the movable suction cup assembly 26 are used, the height of the suction nozzle 29 is adjusted to be higher than that of the fixed suction cup assembly 24 and the movable suction cup assembly 26. This structural design allows for changes in usage without completely disassembling the connecting rod 28, the suction nozzle 29, the fixed suction cup assembly 24, and the movable suction cup assembly 26.

[0036] In this embodiment, the loading and unloading mechanism 7 also includes a material retrieval and descent position controller 32 installed at the bottom of the lifting frame 25. The material retrieval and descent position controller 32 is electrically connected to the loading and unloading moving drive device 6. When the loading and unloading moving drive device 6 drives the loading and unloading mechanism 7 to descend to pick up the board in the loading bin 10, the descent position of the loading and unloading mechanism 7 will change as the board in the loading bin 10 is gradually removed. The material retrieval and descent position controller 32 can control the loading and unloading moving drive device 6 to drive the loading and unloading mechanism 7 to the lowest descent position to ensure that the loading and unloading mechanism 7 can accurately pick up the board.

[0037] In this embodiment, the material handling and lowering controller 32 includes a fixed base 33, a lifting rod 34, a sensor 35, a trigger rod 36, a contact block 37, and a spring 38. The fixed base 33 is installed at the bottom of the lifting frame 25. The fixed base 33 is coaxially provided with a receiving hole 39, a guide hole 40, and a mounting hole 41 from top to bottom. The lifting rod 34 slides through the receiving hole 39, the guide hole 40, and the mounting hole 41. A limiting cap 42 is installed at the top of the lifting rod 34. The limiting cap 42 is located in the receiving hole 39 and is used to abut against the bottom wall of the receiving hole 39. The side wall of the lifting rod 34 is flush with the guide hole 40. The inner wall is slidably connected. The trigger rod 36 is installed at the top of the lifting rod 34, the contact block 37 is installed at the bottom of the lifting rod 34, the sensor 35 is installed on the fixed base 33 and located above the receiving hole 39. The trigger rod 36 is used to trigger the sensor 35. The spring 38 is sleeved on the outside of the lifting rod 34. One end of the spring 38 is inserted into the mounting hole 41 and abuts against the top wall of the mounting hole 41. The other end of the spring 38 abuts against the top surface of the contact block 37. When the spring 38 is in the extended state, the limit cap 42 abuts against the bottom wall of the receiving hole 39, and the trigger rod 36 is located in the receiving hole 39.

[0038] In practical applications, under normal conditions, spring 38 is in the extended state, and both limit cap 42 and trigger rod 36 are located inside receiving hole 39, with limit cap 42 abutting against the bottom wall of receiving hole 39. During the process of loading and unloading mechanism 7 descending and picking up the plate, contact block 37 will contact the plate. As loading and unloading mechanism 7 descends, the plate will exert a squeezing force on contact block 37, causing contact block 37 to move upward along with lifting rod 34 and trigger rod 36, compressing spring 38, until the top of trigger rod 36 moves out of receiving hole 39 and triggers sensor 35. Sensor 35 is triggered, proving that loading and unloading mechanism 7 has descended to the lowest position and accurately picked up the plate. At this time, sensor 35 will send a feedback signal to loading and unloading moving drive device 6, causing loading and unloading moving drive device 6 to drive loading and unloading mechanism 7 to rise along with the plate and transfer the plate for loading. When the loading and unloading mechanism 7 places the plate on the first suction table 4 or the second suction table 5, the spring 38 returns to its elastic state. The rebound force of the spring 38 drives the contact block 37, along with the lifting rod 34 and the trigger rod 36, to descend and reset until the limit cap 42 abuts against the bottom wall of the receiving hole 39 and the trigger rod 36 is located inside the receiving hole 39.

[0039] Specifically, the loading / unloading moving drive device 6 includes two support frames 47 mounted on the table surface of the machine base 1, two longitudinal moving drive mechanisms 48 respectively mounted on the top surfaces of the two support frames 47, a loading / unloading transverse moving drive mechanism 49 respectively connected to the longitudinal moving ends of the two longitudinal moving drive mechanisms 48, and a loading / unloading lifting drive mechanism 50 mounted on the transverse moving end of the loading / unloading transverse moving drive mechanism 49. The loading / unloading mechanism 7 is mounted on the lifting end of the loading / unloading lifting drive mechanism 50, and the loading bin 10 and unloading bin 11 are located between the two support frames 47. In practical applications, the longitudinal moving drive mechanism 48, the loading / unloading transverse moving drive mechanism 49, and the loading / unloading lifting drive mechanism 50 work together to drive the loading / unloading mechanism 7 to move along a preset trajectory path, so as to realize the loading / unloading mechanism 7 to complete the action of picking up and placing the board.

[0040] Specifically, the marking moving drive device 8 includes a gantry frame 51 mounted on the table of the machine base 1, a marking transverse moving drive mechanism 52 mounted on the gantry frame 51, and a marking lifting drive mechanism 53 mounted on the transverse moving end of the marking transverse moving drive mechanism 52. The laser marking device 9 is mounted on the lifting end of the marking lifting drive mechanism 53. The first suction table 4 and the second unloading table are located inside the gantry frame 51. In practical applications, the marking transverse moving drive mechanism 52 and the marking lifting drive mechanism 53 cooperate to drive the laser marking device 9 to move along a preset trajectory path, so as to realize that the laser marking device 9 can complete the laser marking on the board.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] 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.
