Description

Technical Field

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

[0002] Laser engraving utilizes a high-energy-density laser beam focused on the surface of the material being processed, causing the surface to rapidly melt, ablate, and evaporate, forming pits. This allows for non-contact processing of markings (such as QR codes or barcodes), and is widely used in various industries, such as laser engraving on circuit boards.

[0003] Among existing patents, Chinese patent application number 201910682082.5 discloses a dual-station fully automatic laser marking machine for substrates, including a frame and a machine platform mounted on the frame. It also includes a substrate feeding mechanism, a partition feeding mechanism, a finished product collection mechanism, a defective product collection mechanism, a robotic arm transfer mechanism, a camera scanning transfer mechanism, a coding and scanning mechanism, a laser assembly, and two material-carrying worktables mounted on the frame. The material-carrying worktables have loading and unloading positions. The robotic arm transfer mechanism is used to alternately transfer the substrates input by the substrate feeding mechanism to the two material-carrying worktables. The substrate is transferred to the coding and scanning mechanism. The laser component works with the coding and scanning mechanism to laser-code the substrate transferred by the loading table mechanism. The camera scanning and transfer mechanism is used to capture images of the substrate before and / or after laser coding on the loading table mechanism. The coding and scanning mechanism completes the sequential coding and scanning of the substrate. The loading table mechanism transfers the coded substrate to the loading and unloading positions. The robotic transfer mechanism outputs the finished substrate to the finished product collection mechanism or the NG product collection mechanism. The robotic transfer mechanism transfers the partitions input by the partition feeding mechanism to the finished product collection mechanism to complete the staggered stacking of the substrate and the partitions. Although this patent document realizes the alternating delivery of substrates on a dual-platform system and can realize the alternating stacking of partitions and substrates, it cannot separate the partitions and substrates during loading.

[0004] Furthermore, Chinese patent application number 201910977783.1 discloses an automatic loading and unloading laser marking device, comprising: a marking module and a transfer module disposed between a loading module and an unloading module; both the loading module and the unloading module include a support platform, a first material rack, a tray-separating assembly, a conveying assembly, a second material rack, and a tray-receiving assembly, the first material rack and the second material rack being disposed opposite each other on the support platform, one end of the conveying assembly being located below the first material rack and the other end being located below the second material rack, the tray-separating assembly including a first lifting mechanism and a first side support mechanism, the first lifting mechanism being fixed on the support platform and located below the first material rack, and the first side support mechanism being disposed opposite each other at the edge of the first material rack; the tray-receiving assembly including a second lifting mechanism and a second side support mechanism, the second lifting mechanism being located below the second material rack, and the second side support mechanism being disposed opposite each other at the edge of the second material rack. Although the patent document realizes automatic feeding, automatic marking and automatic unloading operations, the marking efficiency is still relatively low because a single transfer module transports the material tray, and it does not have the functions of separating materials and disassembling and stacking boards.

[0005] In addition, the applicant also filed a Chinese patent application on March 6, 2025, with application number 202520379979.1, which discloses a dual-platform laser marking machine. This patent document does not have the functions of separating materials and disassembling and stacking (stacking) plates.

[0006] Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

[0007] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a dual-platform laser engraving machine.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A dual-platform laser engraving machine includes a machine base, a loading machine on one side of the machine base, a unloading machine on the other side of the machine base, two moving drive modules mounted parallel to each other on the machine base, two platforms mounted on the moving ends of the two moving drive modules respectively, a loading device and an unloading device respectively mounted on the machine base and mounted above the two moving drive modules, a lower barcode reader mounted on the machine base, an upper barcode reader mounted above the two moving drive modules, and a laser engraving device mounted on the machine base and mounted above the two moving drive modules. Each material handling machine includes a base located on one side of the machine platform, a storage bin mounted on the base, a separating bin mounted on the base and located on one side of the storage bin, a moving drive mechanism mounted on the base, and a separating and picking robot mounted on the moving end of the moving drive mechanism. The separating and picking robot is movably positioned above the storage bin and the separating bin. The feeding device is equipped with a feeding robot, and the unloading device is equipped with a unloading robot. The feeding robot is movably positioned above the storage bin of the feeding machine and any platform, and the unloading robot is movably positioned above any platform and the storage bin of the unloading machine.

[0009] Furthermore, the machine is equipped with a lower code reading position, an upper and lower material reading position, an upper code reading position, and a laser engraving position. The lower code reading mechanism is located at the lower code reading position, the upper code reading mechanism is located at the upper code reading position, and the laser engraving device is located at the laser engraving position. The platform moves back and forth between the upper and lower material reading position, the upper code reading position, and the laser engraving position. The two platforms move alternately to the upper and lower material reading positions. The loading robot and the unloading robot are both set up corresponding to the upper and lower material reading positions.

[0010] Furthermore, the dual-platform laser engraving machine also includes a defective product collection box installed on the machine base, and a material unloading robot is positioned above any platform, the defective product collection box, and the material storage bin of the unloading machine.

[0011] Furthermore, both the loading robot and the separating and picking robot include a mounting plate, multiple suction cups mounted on the mounting plate, and at least one vibrator mounted on the mounting plate. The vibrator is equipped with a vibrating head, which is located between two adjacent suction cups.

[0012] Furthermore, both the loading robot and the separating and picking robot also include a connecting seat that connects the mounting plate to the suction cup or vibrator.

[0015] Furthermore, a guide block is provided on the top of the connector, and multiple position adjustment guide grooves are provided parallel to each other on the mounting plate. The guide block extends into the position adjustment guide groove and can slide along the length direction of the position adjustment guide groove.

[0016] Furthermore, the guide block is a cube, the position adjustment guide groove is a long strip groove, and the two side walls of the guide block abut against the two opposite inner side walls of the position adjustment guide groove.

[0017] Furthermore, the dual-platform laser engraving machine also includes a housing covering the top surface of the machine base, with a main unit installed inside the machine base. Both the front and rear panels of the housing are equipped with control screens, and both control screens are electrically connected to the main unit.

[0018] The beneficial effects of this utility model are as follows: Initially, a stack of materials consisting of multiple spacers and multiple plates is placed in the storage bin of the loading machine, and a stack of spacers is placed in the spacer bin of the unloading machine. In practical application, the moving drive mechanism of the loading machine drives the spacer picking and placing robot to move above the storage bin. The spacer picking and placing robot picks up the top layer of spacers in the storage bin. Then, the moving drive mechanism drives the spacer picking and placing robot, along with the spacers, to move above the spacer bin of the loading machine. The spacer picking and placing robot places the spacers in the spacer bin. Inside the hopper, simultaneously, the loading robot of the loading device moves above the storage hopper of the loading machine and picks up the topmost plate in the storage hopper. Then, the loading robot moves the picked-up plate to above the lower barcode reader mechanism located at the lower barcode reader position. The barcode reader of the lower barcode reader mechanism scans and reads the lower identification code (such as a QR code or barcode) on the bottom surface of the plate to obtain the information of the plate. After the lower barcode is read, the plate is placed on a platform located at the loading / unloading position, and the moving drive module drives the platform. After the sheet metal part passes through the upper code reading position from the loading and unloading positions, it moves to the laser engraving position. The laser engraving device first identifies and positions the positioning marks on the sheet metal part to determine the required laser engraving location. Then, it accurately laser engraves the sheet metal part. After the laser engraving is completed, the moving drive module drives the platform, along with the laser-engraved sheet metal part, to move to the upper code reading mechanism at the upper code reading position. The digital reader of the upper code reading mechanism scans and reads the upper identification code on the top surface of the laser-engraved sheet metal part to determine whether there is an upper identification code on the top surface of the sheet metal part. The system checks for duplicate codes and whether the upper identification code can be read normally. After the upper code is read, the moving drive module drives the platform, along with the laser-engraved board, to the loading and unloading positions. The unloading robot picks up the laser-engraved board carried by the platform and places it into the storage bin of the unloading machine. Then, the material separation and placement robot of the unloading machine picks up the corresponding material separation material in the material separation bin. The moving drive mechanism of the unloading machine drives the material separation and placement robot, along with the material separation material, to move to the top of the storage bin of the unloading machine. The material separation and placement robot places the material separation material on the top surface of the board in the storage bin. The specific functions of the feeding machine are as follows: before or after the feeding robot removes a board from the storage bin, the separating robot picks up the top layer of separating material from the storage bin and places it into the separating bin, thus separating the materials in the storage bin. The specific functions of the unloading machine are as follows: before or after the unloading robot picks up the laser-engraved board into the storage bin, the separating robot picks up the top layer of separating material from the separating bin and places it above the top layer of the board in the separating bin, thus separating adjacent boards. The specific functions of the two platforms are as follows: when one platform moves with the board to be laser-engraved from the loading / unloading position to the laser-engraving position, the other platform moves with the laser-engraved board from the laser-engraving position to the loading / unloading position, so that the two platforms move alternately, greatly improving the efficiency of loading, laser-engraving, coding, and unloading of boards.Furthermore, the loading and unloading machines are respectively assembled on both sides of the machine base, realizing modular assembly of the loading machine, machine base, and unloading machine. They can be used independently (single machine use) or assembled in combination, offering flexibility and convenience, and facilitating transportation and packaging. This utility model significantly improves the efficiency of loading, laser engraving, coding, and unloading of plates by alternately conveying them through two platforms. It not only enables the alternating stacking of laser-engraved plates and spacers during unloading but also allows for the separation of laser-engraved plates and spacers during loading.

[0026] 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.

[0027] like Figures 1 to 6As shown, this utility model provides a dual-platform laser engraving machine, which includes a machine base 1, a loading machine 2 disposed on one side of the machine base 1, a unloading machine 3 disposed on the other side of the machine base 1, two moving drive modules 4 mounted parallel to each other on the machine base 1, two platforms 5 respectively mounted on the moving ends of the two moving drive modules 4, a loading device 6 and an unloading device 7 respectively mounted on the machine base 1 and mounted above the two moving drive modules 4, a lower code reading mechanism 8 mounted on the machine base 1, an upper code reading mechanism 9 mounted above the two moving drive modules 4, and a laser engraving device 10 mounted on the machine base 1 and mounted above the two moving drive modules 4. Both the loading machine 2 and the unloading machine 3 include a position... The machine base 11 is located on one side of the machine base 1. The storage bin 12 is installed on the machine base 11. The separating bin 13 is installed on the machine base 11 and located on one side of the storage bin 12. The moving drive mechanism 14 is installed on the machine base 11. The separating and picking robot 15 is installed on the moving end of the moving drive mechanism 14. The separating and picking robot 15 is movably arranged above the storage bin 12 and the separating bin 13. The feeding device 6 is equipped with a feeding robot 16. The unloading device 7 is equipped with an unloading robot 17. The feeding robot 16 is movably arranged above the storage bin 12 of the feeding machine 2 and any platform 5. The unloading robot 17 is movably arranged above any platform 5 and the storage bin 12 of the unloading machine 3. Specifically, the machine base 1 is equipped with a lower code reading position, a loading / unloading position, an upper code reading position, and a laser engraving position. The lower code reading mechanism 8 is located at the lower code reading position, the upper code reading mechanism 9 is located at the upper code reading position, and the laser engraving device 10 is located at the laser engraving position. The platform 5 moves back and forth between the loading / unloading position, the upper code reading position, and the laser engraving position. The two platforms 5 move alternately to the loading / unloading position. The loading robot 16 and the unloading robot 17 are both set corresponding to the loading / unloading positions. The loading machine 2 and the unloading machine 3 are symmetrically arranged on both sides of the machine base 1. The laser engraving device 10 is a laser engraving mechanism with a CCD. The moving drive mechanism 14 can drive the material handling robot 15 to move horizontally and vertically.

[0028] Initially, a stack of materials, consisting of multiple spacers and multiple plates stacked alternately, is placed in the storage bin 12 of the loading machine 2, and a stack of spacers is placed in the spacer bin 13 of the unloading machine 3. In actual application, the moving drive mechanism 14 of the loading machine 2 drives the spacer picking and placing robot 15 to move above the storage bin 12. The spacer picking and placing robot 15 picks up the top layer of spacers in the storage bin 12, and then the moving drive mechanism 14 drives the spacer picking and placing robot 15, along with the spacers, to move above the spacer bin 13 of the loading machine 2. The spacer picking and placing robot 15 then places the spacers in the spacer bin 13. Inside bin 13, simultaneously, the loading robot 16 of the loading device 6 moves above the storage bin 12 of the loading machine 2 and picks up the topmost plate in the storage bin 12. Then, the loading robot 16 moves the picked-up plate to above the lower barcode reading mechanism 8 located at the lower barcode reading position. The barcode reader of the lower barcode reading mechanism 8 scans and reads the lower identification code (such as a QR code or barcode) on the bottom surface of the plate to obtain the information of the plate. After the lower barcode reading is completed, the plate with the barcode is placed on a platform 5 located at the loading and unloading position, and the moving drive module 4 drives the platform 5. After the board is moved from the loading / unloading position through the upper code reading position to the laser engraving position, the laser engraving device 10 first identifies and positions the positioning marks on the board to determine the required laser engraving position, and then accurately laser engraves the board. After the laser engraving is completed, the moving drive module 4 drives the platform 5 to move the laser-engraved board to the upper code reading mechanism 9 located at the upper code reading position. The digital device of the upper code reading mechanism 9 scans and reads the upper identification code on the top surface of the laser-engraved board to determine whether there is an upper identification code on the top surface of the board, whether there are duplicate codes, and whether the upper identification code is correct. After the code reading is completed, the mobile drive module 4 drives the platform 5, along with the laser-engraved board, to move to the loading and unloading position. The unloading robot 17 of the unloading device 7 picks up the laser-engraved board carried by the platform 5 and puts it into the storage bin 12 of the unloading machine 3. Then, the material separation and picking robot 15 of the unloading machine 3 picks up the material separation in the corresponding material separation bin 13. The mobile drive mechanism 14 of the unloading machine 3 drives the material separation and picking robot 15, along with the material separation, to move to the top of the storage bin 12 of the unloading machine 3. The material separation and picking robot 15 places the material separation on the top surface of the board in the storage bin 12.The specific operation of the feeding machine 2 is as follows: before or after the feeding robot 16 removes a board from the storage bin 12, the separating robot 15 picks up the top layer of separating material in the storage bin 12 and places it into the separating bin 13 to separate the material in the storage bin 12; the specific operation of the unloading machine 3 is as follows: before or after the unloading robot 17 picks up the laser-engraved board into the storage bin 12, the separating robot 15 picks up the top layer of separating material in the separating bin 13 and places it above the top layer of the board in the separating bin 13, so that two adjacent boards are separated by separating material; the specific operation of the two platforms 5 is as follows: when one platform 5 moves with the board to be laser-engraved from the loading / unloading position to the laser-engraving position, the other platform 5 moves with the laser-engraved board from the laser-engraving position to the loading / unloading position, so that the two platforms 5 move alternately, which greatly improves the efficiency of loading, laser-engraving, coding and unloading of boards. In addition, the loading machine 2 and unloading machine 3 are respectively assembled on both sides of the machine base 1, realizing the modular assembly of the loading machine 2, machine base 1 and unloading machine 3. They can be used independently (single machine use) or assembled and used in combination, which is flexible and convenient to use, and facilitates transportation and packaging. This utility model greatly improves the efficiency of loading, laser engraving, code reading and unloading of plates by alternately conveying the plates on two carriers 5. It can not only realize the alternating stacking of laser-engraved plates and partitions during unloading, but also realize the disassembly of plates to be laser-engraved and partitions during loading.

[0029] Specifically, the lower code reading mechanism 8 is located between a mobile drive module 4 and the storage bin 12 of the loading machine 2. This structural design shortens the movement path of the loading robot 16 and improves the efficiency of the loading robot 16 in transferring the board.

[0030] Preferably, the separator is a paper or glue sheet, and the board is a circuit board.

[0031] In this embodiment, the dual-platform laser engraving machine also includes a defective product collection box 18 installed on the machine base 1, and a material unloading robot 17 is movably positioned above any of the platforms 5, the defective product collection box 18, and the storage bin 12 of the material unloading machine 3. Specifically, the defective product collection box 18 is located between a moving drive module 4 and the storage bin 12 of the material unloading machine 3. In practical applications, when the upper code reading mechanism 9 detects problems such as the absence of an upper identification code, duplicate codes, or inability to read codes on the board, and the platform 5 moves with the board to the loading / unloading position, the material unloading robot 17 picks up the defective board and places it into the defective product collection box 18, which stores the defective board.

[0032] In this embodiment, both the loading robot 16 and the separating and picking robot 15 include a mounting plate 19, a plurality of suction cups 20 disposed on the mounting plate 19, and at least one vibrator 21 disposed on the mounting plate 19. The vibrator 21 is provided with a vibrating head 22, which is located between two adjacent suction cups 20. Specifically, the vibrator 21 can be an existing device such as a vibrating cylinder.

[0033] During the process of the loading robot 16 picking up the board in the storage bin 12 of the loading machine 2, multiple suction cups 20 hold the board, and the vibrator 21 drives the vibrating head 22 to vibrate at high frequency, so that the picked-up board is separated from the partition below it, avoiding the problem of stacking. During the process of the partition picking and placing robot 15 of the loading machine 2 picking up the partition in the storage bin 12 of the loading machine 2, multiple suction cups 20 hold the partition tightly, and the vibrator 21 drives the vibrating head 22 to vibrate at high frequency, so that the picked-up partition is separated from the board below it, avoiding the problem of stacking. During the process of the partition picking and placing robot 15 of the unloading machine 3 picking up the partition in the partition bin 13 of the unloading machine 3, multiple suction cups 20 hold the partition tightly, and the vibrator 21 drives the vibrating head 22 to vibrate at high frequency, so that the picked-up partition is separated from the partition below it, avoiding the problem of stacking.

[0034] Specifically, the structure of the unloading robot 17 can be the same as that of the loading robot 16, or it can adopt the structure of the loading robot 16 without the vibrator 21.

[0035] In this embodiment, both the loading robot 16 and the separating and picking robot 15 further include a connecting seat 23 connected between the mounting plate 19 and the suction cup 20 or the vibrator 21. This structural design facilitates the assembly and disassembly of the suction cup 20 or the vibrator 21 from the mounting plate 19.

[0036] In this embodiment, the mounting plate 19 is a metal plate capable of magnetically attracting the magnet 24. The top of the connecting seat 23 is equipped with the magnet 24, which magnetically attracts the mounting plate 19. The connecting seat 23 is magnetically attracted to the mounting plate 19 by the magnet 24, so that the connecting seat 23 is firmly assembled on the mounting plate 19. This not only facilitates the assembly and disassembly of the connecting seat 23 and the mounting plate 19, but also facilitates the adjustment of the position of the connecting seat 23 on the mounting plate 19, thereby facilitating the adjustment of the position of the suction cup 20 or the vibrator 21 to meet the needs of picking up and placing plates or spacers of different sizes.

[0037] In this embodiment, the top surface of the connector 23 is recessed with an insert hole 25, and the magnet 24 is inserted into the insert hole 25. The magnet 24 is locked to the top of the connector 23 by a fastener. This structural design facilitates the positioning and assembly of the magnet 24 and the connector 23, and the structure is compact.

[0038] In this embodiment, a guide block 26 is provided at the top of the connecting seat 23, and multiple position adjustment guide grooves 27 are provided parallel to each other on the mounting plate 19. The guide block 26 extends into the position adjustment guide groove 27 and can slide along the length direction of the position adjustment guide groove 27. When the connecting seat 23 is adjusted relative to the mounting plate 19, the connecting seat 23 is moved so that the guide block 26 on the connecting seat 23 moves along the corresponding position adjustment guide groove 27 until the connecting seat 23 moves to the appropriate position.

[0039] In this embodiment, the guide block 26 is a cube, and the position adjustment guide groove 27 is an elongated groove. The two side walls of the guide block 26 respectively abut against the two opposite inner side walls of the position adjustment guide groove 27. This structural design prevents the guide block 26 from rotating within the position adjustment guide groove 27.

[0040] In this embodiment, the dual-platform laser engraving machine also includes a housing 28 covering the top surface of the machine base 1. The machine base 1 houses the main unit. Both the front and rear panels of the housing 28 are equipped with control screens 30, and both control screens 30 are electrically connected to the main unit. The interconnection of the two control screens 30 facilitates machine operation and adjustment by the operator, reducing the need for the operator to frequently move between the front and rear sides of the housing 28 to control the control screens 30.

[0041] Specifically, both the feeding machine 2 and the unloading machine 3 include a cover 29 covering the top surface of the machine base 11. The storage bin 12, the separating bin 13, the moving drive mechanism 14 and the separating and picking robot 15 are all located inside the cover 29. The cover 29 of the feeding machine 2 and the cover 29 of the unloading machine 3 are respectively spliced ​​and connected to the two sides of the machine shell 28.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] 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.
