Description

Technical Field

[0001] This application relates to the field of laser engraving technology, and in particular to an intelligent automated laser engraving device. Background Technology

[0002] Intelligent automated laser engraving equipment differs from traditional standard laser engraving equipment in its production model. Traditional standard laser engraving machines are generally used for single-process production. From product removal, product mounting on the fixture, fixture positioning, laser engraving switch activation, fixture removal, product removal, and product placement on the pallet, each step requires manual operation. After laser engraving, the product also needs to be transferred to the next process for manual appearance inspection. In contrast, intelligent automated laser engraving equipment can not only automate all the manual tasks of traditional laser engraving machines but also achieve automatic inspection and judgment capabilities. Summary of the Invention

[0003] To improve laser engraving efficiency, this application provides an intelligent automated laser engraving device.

[0004] The intelligent automated laser engraving equipment provided in this application adopts the following technical solution:

[0005] An intelligent automated laser engraving equipment includes a loading platform, a processing platform, and an unloading platform. A pallet conveying device and a laser engraving device are mounted on the processing platform, located on opposite sides of the processing platform. A loading component and an unloading component are positioned between the pallet conveying device and the laser engraving device. The loading component transfers parts from the pallet conveying device to the laser engraving device, and the unloading component transfers parts processed by the laser engraving device to the pallet conveying device. The equipment also includes two transfer components, located on the loading platform and the unloading platform respectively. The transfer component on the loading platform transfers a pallet containing parts from the loading platform to the pallet conveying device, and the transfer component on the unloading platform transfers a pallet containing laser-engraved parts to the unloading platform.

[0006] Optionally, the laser engraving device includes an annular transfer guide rail, a transfer table, a fixture, a monitoring component, an engraving component, and a first driving component, all mounted on a processing table. The transfer table is slidably mounted on the annular transfer guide rail. The fixture is fixedly mounted on the transfer table to fix the workpiece to be laser engraved. The monitoring component is used to identify the workpiece size. The engraving component is used to laser engrave the workpiece. The first driving component is used to drive the transfer table to move on the annular transfer guide rail, causing the workpiece to pass sequentially through the monitoring component and the engraving component.

[0007] Optionally, the first driving component includes a drive motor, drive wheels, and a drive belt mounted on a processing table. The length direction of the output shaft of the drive motor is perpendicular to the processing table. There are two drive wheels: one drive wheel is coaxially mounted on the output shaft of the drive motor, and the other drive wheel is located on one side of the processing table. The drive belt is wound around the two drive wheels. The inner ring of the drive belt and the peripheral wall of the drive wheel are provided with mutually meshing rectangular grooves. The drive belt is located in the space surrounded by an annular transfer guide rail. The transfer table is movably connected to the drive belt.

[0008] Optionally, both the loading and unloading components include mounting rods, transverse guide rails, sliding seats, lifting cylinders, mounting plates, and suction components. Two mounting rods are provided, one located within the space surrounded by the drive belt and the other located outside the pallet conveyor. The transverse guide rails are fixedly mounted on the two mounting rods. The sliding seats are slidably mounted on the transverse guide rails. The lifting cylinder is fixedly mounted on the surface of the sliding seats facing the processing table. The mounting plate is fixedly mounted on the output shaft of the lifting cylinder. The suction component is mounted on the mounting plate and used to fix the workpiece to the suction component.

[0009] Optionally, the suction device includes an air pump, an air needle, and a buffer tube. The air pump is mounted on the processing table, the air needle is connected to the air pump through an air tube, the buffer tube is coaxially mounted on the air needle, the mounting plate is parallel to the processing table and has a mounting notch, the air needle is fixed to the mounting plate through the mounting notch, and the mounting notch is opened along the length direction of the mounting plate to adjust the position of the air needle on the mounting plate.

[0010] Optionally, the pallet conveying device includes a conveying guide rail, a partition plate, and a lifting plate arranged on the processing table. There are two conveying guide rails arranged at intervals. The pallet is transferred to the conveying guide rail by a transfer component. The partition plate is used to block the pallet from being conveyed on the conveying guide rail. Both the partition plate and the lifting plate are raised and lowered on the processing table. After the pallet is conveyed above the lifting plate, it is blocked by the partition plate. The lifting plate rises and falls, causing the pallet to separate from the conveying guide rail. After the lifting plate lifts the pallet, the loading component or unloading component is used to grab or lower the workpiece on the pallet.

[0011] Optionally, multiple partition plates and lifting plates are provided, arranged sequentially along the length of the conveying guide rail as a first partition plate, a first lifting plate, a second partition plate, a third partition plate, a second lifting plate, and a fourth partition plate. After the loading component transfer pallet is placed on the conveying guide rail, it is conveyed to the first partition plate. After passing the first lifting plate, the pallet is blocked by the second partition plate. The first lifting plate rises and receives the pallet, separating it from the conveying guide rail. Then, a transfer component transfers the workpiece on the pallet to the laser engraving device. Subsequently, the first lifting plate falls, causing the pallet to fall onto the conveying guide rail, where it is conveyed to the third partition plate. When passing the second lifting plate, the fourth partition plate blocks the pallet. The second lifting plate causes the empty pallet to rise, and the transfer component transfers the laser-engraved workpiece to the empty pallet, which is then conveyed to the end by the conveying guide rail.

[0012] Optionally, both the loading platform and the unloading platform include a housing, a positioning frame, a sliding plate, and a lifting component. The positioning frame, the sliding plate, and the lifting component are all located inside the housing. The side and top surfaces of the housing are provided with removal outlets. The sliding plate is slidably disposed inside the housing and moves out from the removal outlet on the side of the housing. The lifting component includes a lifting plate disposed on the sliding plate and a second driving component. The positioning frame is fixedly disposed on the lifting plate. The second driving component is used to drive the lifting plate to slide and move the stacked tray out from the removal outlet on the top surface of the housing.

[0013] Optionally, the lifting plate is provided with a through groove on the top surface of the lifting plate, and the bottom surface of the through groove is provided with multiple clamping notches. The length direction of the clamping notches is perpendicular to the conveying direction of the pallet. After the pallet is placed on the lifting plate, the pallet falls into the clamping notches. A fixing member is provided on the lifting plate and located in the clamping notches. The fixing member is used to fix the edge of the pallet that falls into the clamping notches.

[0014] Optionally, the lifting plate between adjacent clamping notches has an installation notch, which is used to connect adjacent clamping notches. The fixing member includes a fixing airbag and a connecting pipe embedded in the installation notch. The connecting pipe enters the lifting plate through the bottom surface of the lifting plate and communicates with the fixing airbag.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] During laser engraving, the workpiece is placed in a tray, which is then placed on the loading platform. The tray is then transferred to the tray conveyor via a transfer unit. The tray conveyor then transports the tray to the laser engraving device. The workpiece is then transferred from the tray to the laser engraving device via the loading unit. After the laser engraving device processes the workpiece, the unloading unit transfers the processed workpiece back to the tray. Once the tray is full, the tray conveyor transports the tray to the rear of the processing table. The unloading unit then transfers the tray to the unloading table. In this process, the laser engraving process is completed automatically, thereby improving the efficiency of laser engraving.

[0017] After the workpiece is transferred to the transfer table, it passes through the monitoring component and the engraving component in sequence. During this process, the monitoring component collects the dimensional data of the workpiece. Qualified workpieces are laser engraved, while unqualified workpieces pass through the engraving component instead of being processed. This realizes the ability to automatically inspect and judge the workpiece, thereby improving the processing quality of the workpiece. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 This application will be described in further detail.

[0037] This application discloses an intelligent automated laser engraving device. (Refer to...) Figure 1 and Figure 2The intelligent automated laser engraving equipment includes a loading platform 1, a processing platform 2, and a unloading platform 3. The processing platform 2 is equipped with a pallet conveying device 4 and a laser engraving device 5, which are located on the horizontal sides of the processing platform 2, respectively. A loading component 6 and an unloading component 7 are arranged between the pallet conveying device 4 and the laser engraving device 5. The loading component 6 is used to transfer the parts on the pallet conveying device 4 to the laser engraving device 5, and the unloading component 7 is used to transfer the parts processed by the laser engraving device 5 to the pallet conveying device 4. It also includes a transfer component 8, of which there are two, located on the loading platform 1 and the unloading platform 3, respectively. The transfer component 8 on the loading platform 1 is used to transfer the pallet with parts on the loading platform 1 to the pallet conveying device 4, and the transfer component 8 on the unloading platform 3 is used to transfer the pallet with laser-engraved parts to the unloading platform 3.

[0038] During laser engraving, the workpiece is placed in a tray, which is then placed on the loading platform 1. The tray is then transferred from the loading platform 1 to the tray conveyor 4 via the transfer component 8. The tray is then conveyed to the laser engraving device 5 via the tray conveyor 4. The workpiece is then transferred from the tray to the laser engraving device 5 via the loading component 6. After the workpiece is processed by the laser engraving device 5, the processed workpiece is transferred back to the tray by the unloading component 7. When the tray is full, the tray conveyor 4 conveys the tray to the rear end of the processing table 2. The tray is then transferred to the unloading table 3 by the transfer component 8. In the above process, the laser engraving process is completed automatically, thereby improving the laser engraving efficiency of the workpiece.

[0039] Reference Figure 3 , Figure 4 and Figure 5 In this embodiment of the application, the laser engraving device 5 includes an annular transfer guide rail 51, a transfer table 52, a clamp 53, a monitoring component 54, an engraving component 55, and a first driving component 56, which are disposed on the processing table 2. The annular transfer guide rail 51 is elongated, the transfer table 52 is slidably disposed on the annular transfer guide rail 51, and the transfer table 52 slides along the annular transfer guide rail 51. The clamp 53 is fixedly disposed on the transfer table 52 to fix the workpiece to be laser engraved.

[0040] Reference Figure 3 , Figure 4 and Figure 5 The monitoring component 54 is used to identify the size of the workpiece. In this embodiment, the monitoring component 54 includes multiple camera modules 541 set on the processing table 2. The body of the camera module 541 is fixedly set on the processing table 2. The lens end of the camera is located directly below the transfer table 52. The transfer table 52 is hollowed out to install the clamp 53. The clamp 53 is hollowed out corresponding to the part of the workpiece to be detected and is facing the lens end of the camera. The camera module 541 is connected to the control panel of the laser engraving equipment and sends the captured workpiece photo to the control panel to display the workpiece size information on the control panel.

[0041] Reference Figure 3 , Figure 4 and Figure 5 The engraving part 55 is used for laser engraving on the workpiece. The engraving part 55 includes a laser 551 and a push plate 552 set on the processing table 2. The push plate 552 is located below the laser 551 and is slidably set on the processing table 2. The push plate 552 faces the workpiece and slides in the direction of the workpiece. The push plate 552 is provided with a fixing pin in the direction of the workpiece. The processing table 2 is provided with a first cylinder to drive the push plate 552 to slide.

[0042] Reference Figure 3 , Figure 4 and Figure 5 The first driving component 56 is used to drive the transfer table 52 to move on the annular transfer guide rail 51, thereby causing the workpiece to pass through the monitoring component 54 and the engraving component 55 in sequence.

[0043] When the workpiece is transported from the first driving component 56 to the monitoring component 54, the camera module 541 takes a picture of the workpiece from the bottom of the transfer table 52 and the fixture 53, and transmits the data to the control panel. The control panel compares the size signal, and the workpiece whose size meets the set value is transported to the engraving component 55. At this time, the first cylinder drives the push plate 552 to move the fixing pin toward the workpiece and abut against the workpiece, thereby positioning the workpiece. Then, the laser 551 works on the workpiece to perform laser engraving. After the workpiece is engraved, it is transported to the next stage by the transfer table 52.

[0044] Reference Figure 3 , Figure 4 and Figure 5 In this embodiment, the first driving component 56 includes a driving motor 561, a driving wheel 562, and a driving belt 563 mounted on the processing table 2. The length direction of the output shaft of the driving motor 561 is perpendicular to the processing table 2. There are two driving wheels 562, one of which is coaxially mounted on the output shaft of the driving motor 561, and the other is located on one side of the processing table 2. The driving belt 563 is wound around the two driving wheels 562. The inner ring of the driving belt 563 and the peripheral wall of the driving wheel 562 are provided with mutually meshing rectangular grooves 9. The driving belt 563 is located in the space surrounded by the annular transfer guide rail 51. The transfer table 52 is movably connected to the driving belt 563.

[0045] When the workpiece moves on the annular transfer guide rail 51, the drive motor 561 is started. The drive motor 561 drives the coaxially arranged drive wheel 562 to rotate. Since the inner ring of the drive belt 563 and the rectangular groove 9 on the peripheral wall of the drive wheel 562 mesh with each other, the drive belt 563 moves accordingly, thereby driving the transfer table 52, which is movably connected to the drive belt 563, to slide on the annular transfer guide rail 51. The transfer table 52 drives the workpiece to move horizontally on the annular guide rail, which facilitates the transfer of the workpiece from the pallet to the transfer table 52 to the monitoring part 54 and the engraving part 55. After engraving, the workpiece moves away from the engraving part 55, thus realizing the sequential transfer of the workpiece between the monitoring part 54 and the engraving part 55.

[0046] Reference Figure 3 In this embodiment, both the loading component 6 and the unloading component 7 include mounting rods 10, transverse guide rails 11, sliding seats 12, lifting cylinders 13, mounting plates 14, and suction components 15. Two mounting rods 10 are provided: one located within the space surrounded by the drive belt 563, and the other located outside the pallet conveying device 4. The transverse guide rails 11 are fixedly mounted on the two mounting rods 10, and the sliding seats 12 are slidably mounted on the transverse guide rails 11. Furthermore, a screw drive device 16 is rotatably mounted on the transverse guide rails 11. The lead screw drive device 16 includes a lead screw 161 rotatably mounted on a transverse guide rail 11 and a drive motor 162. The length direction of the lead screw 161 is parallel to the length direction of the transverse guide rail 11. A sliding seat 12 is threadedly connected to the lead screw 161. The lead screw 161 is coaxially mounted on the output shaft of the drive motor 162. A lifting cylinder 13 is fixedly mounted on the surface of the sliding seat 12 facing the processing table 2. A mounting plate 14 is fixedly mounted on the output shaft of the lifting cylinder 13. A suction member 15 is mounted on the mounting plate 14 and is used to fix the workpiece to the suction member 15.

[0047] When a workpiece is transferred from a pallet to a transfer table 52 or vice versa, the drive motor 162 is started. The drive motor 162 drives the lead screw 161 to rotate. The rotation of the lead screw 161 causes the sliding seat 12 to slide. The sliding seat 12 causes the lifting cylinder 13 and the suction component 15 to slide directly above the workpiece. Then, the lifting cylinder 13 is started. The lifting cylinder 13 drives the mounting plate 14 to move the suction component 15 toward the workpiece and make contact with it, thereby fixing the workpiece on the mounting plate 14. Then, the lead screw 161 drives the workpiece to reciprocate between the pallet and the transfer table 52. The operation is simple and convenient.

[0048] Reference Figure 3In this embodiment, the suction component 15 includes an air pump, an air needle 151, and a buffer tube 152. The air pump is mounted on the processing table 2, and the air needle 151 is connected to the air pump via an air pipe. When clamping a workpiece, the air pump is activated. When the air pump is working, it can deliver or extract gas to or from the air needle 151 through the air pipe, thereby enabling the air needle 151 to suction and release the workpiece. The operation is simple and convenient. Furthermore, the buffer tube 152 is coaxially mounted on the air needle 151 and is a retractable rubber tube. When the air needle 151 suctions the workpiece, the buffer tube 152 prevents the air needle 151 from directly contacting the workpiece, thus reducing the possibility of workpiece damage and improving the quality of the workpiece.

[0049] Reference Figure 6 In this embodiment, the transfer component 8 includes a fixed plate 81, a horizontal plate 82, a screw drive device 16, a mounting base 83, a transfer cylinder 84, a transfer plate 85, and multiple air needles 151. The fixed plate 81 is fixedly mounted on the loading platform 1 or the unloading platform 3. The horizontal plate 82 is fixedly mounted on the fixed plate 81. The screw drive device 16 is fixedly mounted on the horizontal plate 82. The mounting base 83 is threadedly connected to the screw drive device 16. The transfer cylinder 84 is fixedly mounted on the mounting base 83. The transfer plate 85 is parallel to the processing table 2. The air needles 151 are mounted on the transfer plate 85. When transferring a pallet, the transfer plate 85 moves horizontally to directly above the pallet. The transfer cylinder 84 drives the transfer plate 85 and the air needles 151 to approach and abut against the pallet. Then, the screw drive device 16 drives the pallet to move horizontally onto the pallet conveying device 4. The operation is simple and convenient.

[0050] Reference Figure 3 To facilitate the handling of workpieces of different specifications, the mounting plate 14 is parallel to the processing table 2 and has a mounting notch 17. The air needle 151 is fixed to the mounting plate 14 through the mounting notch 17. The mounting notch 17 is opened along the length of the mounting plate 14 to adjust the position of the air needle 151 on the mounting plate 14. According to the size and shape of different workpieces, the position of the air needle 151 is adjusted laterally to adapt to different specifications of workpieces. Furthermore, the position of the air needle 151 is adjusted so that the air needle 151 is directly facing the horizontal position of the workpiece to improve the stability and accuracy of the suction.

[0051] Reference Figure 7 and Figure 8In this embodiment, the pallet conveying device 4 includes a conveying guide rail 41, a partition plate, and a lifting plate disposed on the processing table 2. Two conveying guide rails 41 are provided and spaced apart. Each conveying guide rail 41 includes a first plate 411 and a second plate 412 in the shape of a long strip. The second plate 412 is located outside the first plate 411 and adheres to it, and is fixed to the first plate 411 by bolts. Two conveying rollers 42 are disposed between the two conveying guide rails 41, and the conveying rollers 42 are rotatably mounted on the two rails. Between the second plates 412, the peripheral wall of the conveyor roller 42 is recessed to form a limiting groove. Furthermore, it also includes a conveyor belt 43, which is wound around the conveyor roller 42 and located in the limiting groove. Furthermore, it also includes a drive rod 44, which is used to connect the two transverse conveyor rollers 42. A conveyor motor 45 is provided on the processing table 2, and the drive rod 44 is coaxially mounted on the conveyor motor 45. Furthermore, guide grooves are provided on both the upper and lower sides of the first plate 411, and the conveyor belt 43 is located in the guide groove.

[0052] The pallet is transferred to the conveyor rail 41 by the transfer component 8. The partition plate is used to block the pallet from being conveyed on the conveyor rail 41. Both the partition plate and the lifting plate are raised and lowered on the processing table 2. After the pallet is conveyed above the lifting plate, it is blocked by the partition plate. The lifting plate rises and falls, causing the pallet to separate from the conveyor rail 41. After the lifting plate lifts the pallet, the loading component 6 or the unloading component 7 is used to grab or lower the workpiece on the pallet.

[0053] When the pallet is transferred from the loading platform 1 to the conveyor belt 43, the conveyor motor 45 drives the connecting rod to rotate. The rotation of the connecting rod drives the drive roller to rotate, which in turn drives the conveyor belt 43 to move the pallet. The operation is simple and convenient. Furthermore, when the pallet is transported to the designated position, the partition plate can stop the pallet from moving forward to allow for subsequent operations. At this time, operations such as grabbing or placing the workpiece on the pallet can be performed. After the lifting plate lifts the pallet, the workpiece can be transferred between the pallet and the laser engraving device 5.

[0054] Reference Figure 7 In this embodiment of the application, a lifting cylinder 46 is provided on the processing table 2. The length direction of the piston rod of the lifting cylinder 46 is perpendicular to the processing table 2. The partition plate and the lifting plate are respectively fixedly arranged on the piston rod of the lifting cylinder 46.

[0055] Reference Figure 7In this embodiment, multiple partition plates and lifting plates are provided, arranged sequentially along the length of the conveying guide rail 41 as a first partition plate 47, a first lifting plate 48, a second partition plate 49, a third partition plate 410, a second lifting plate 413, and a fourth partition plate 414. After the loading component 6 transfers the pallet onto the conveying guide rail 41, it is conveyed by the conveying guide rail 41 to the first partition plate 47. After the pallet passes the first lifting plate 48, it is blocked by the second partition plate 49. The first lifting plate 48 rises and receives the pallet, which then separates from the conveying guide rail 41. The transfer component 8 then... The workpiece on the pallet is transferred to the laser engraving device 5. Then, the first lifting plate 48 falls and causes the pallet to fall onto the conveying guide rail 41. The pallet is then conveyed by the conveying guide rail 41 to the third partition plate 410. When the pallet passes the second lifting plate 413, the fourth partition plate 414 blocks the pallet. The second lifting plate 413 causes the empty pallet to rise. The laser-engraved workpiece is then transferred to the empty pallet by the transfer component 8 and then conveyed to the end by the conveying guide rail 41. Through the cooperation of multiple partition plates and lifting plates, precise control of the pallet during the conveying process and automated transfer of the workpiece are achieved.

[0056] Reference Figure 1 and Figure 6 In this embodiment, both the loading platform 1 and the unloading platform 3 include a housing 18, a positioning frame 19, a sliding plate 20, and a lifting component. The positioning frame 19, the sliding plate 20, and the lifting component are all located inside the housing 18. The side and top surfaces of the housing 18 are provided with removal outlets. The sliding plate 20 is slidably disposed inside the housing 18 and moves out from the side removal outlet of the housing 18. When it is necessary to take or store a pallet, the sliding plate 20 can be moved out from the side of the housing 18, which is simple and convenient to operate. The lifting mechanism includes a lifting plate 21 mounted on a sliding plate 20 and a second driving component. A positioning frame 19 is fixedly mounted on the lifting plate 21. The second driving component is used to drive the lifting plate 21 to slide, thereby moving the stacked trays out of the removal outlet on the top surface of the box 18. The lifting plate 21 can be moved up and down through the second driving component, thereby moving the positioning frame 19 and the trays out of the top surface of the box 18, which facilitates the operation of the trays. The second driving component includes a screw drive device 16 mounted inside the box 18. The lifting plate 21 is threadedly connected to the screw drive device 16, thereby driving the lifting plate 21 to move up and down inside the box 18, thereby moving the trays stacked on the lifting plate 21 upward as a whole, and moving the topmost tray out of the removal outlet.

[0057] Reference Figure 9In this embodiment, to improve the stability of the pallet on the lifting plate, a through groove 22 is provided on the lifting plate. The through groove 22 is located on the top surface of the lifting plate, and multiple clamping notches 23 are provided on the bottom surface of the through groove 22. The length direction of the clamping notches 23 is perpendicular to the conveying direction of the pallet. After the pallet is placed on the lifting plate, the pallet falls into the clamping notches 23, which can initially position the pallet. The bottom surface of the pallet falls on the bottom surface of the through groove 22, increasing the contact area between the pallet and the lifting plate and thus improving the stability of the pallet. A fixing member is provided on the lifting plate and located within the clamping notches 23. The fixing member is used to fix the edge of the pallet falling into the clamping notches 23, preventing the pallet from moving during the lifting process and reducing the possibility of the pallet moving, shifting, or tilting due to the air needle 151 contacting the pallet during the process of the air needle 151 picking up the pallet.

[0058] Reference Figure 9 In this embodiment, the lifting plate between adjacent clamping notches 23 is provided with an installation notch 17. The installation notch 17 is used to connect the adjacent clamping notches 23. The fixing component includes a fixing airbag and a connecting pipe embedded in the installation notch 17. The connecting pipe enters the lifting plate through the bottom surface of the lifting plate and communicates with the fixing airbag. When the pallet is placed on the lifting plate, the edge of the pallet falls into the clamping notch 23. Then, air is injected into the fixing airbag through the connecting pipe to expand the fixing airbag, thereby clamping the edge of the pallet and fixing the pallet on the lifting plate. This further improves the stability of the pallet and reduces the possibility of the pallet shifting when loading or unloading workpieces, thus facilitating the loading and unloading of workpieces.

[0059] The implementation principle of an intelligent automated laser engraving device according to an embodiment of this application is as follows:

[0060] When laser engraving a workpiece, the workpiece is placed in a tray, and then the tray is placed on the loading platform 1. Subsequently, the lifting plate 21 is moved by the screw drive device 16, which in turn moves the top tray out of the box 18.

[0061] When transferring a pallet, the transfer plate 85 moves horizontally to directly above the pallet, and the transfer cylinder 84 drives the transfer plate 85 and the air needle 151 to approach and contact the pallet. Then, the screw drive device 16 drives the pallet to move horizontally onto the pallet conveying device 4.

[0062] After being conveyed by the conveyor rail 41 to the first partition plate 47, the pallet passes the first lifting plate 48 and is blocked by the second partition plate 49. The first lifting plate 48 rises and receives the pallet, which then separates from the conveyor rail 41. The transfer component 8 transfers the workpiece on the pallet to the laser engraving device 5. When the workpiece is conveyed by the first driving component 56 to the monitoring component 54, the camera module 541 takes a picture of the workpiece from the bottom of the transfer table 52 and the fixture 53 and transmits the data to the control panel. The control panel compares the size signal. Workpieces whose size meets the set parameters are conveyed to the engraving component 55. At this time, the first cylinder drives the push plate 552 to move the fixing pin toward the workpiece and abut against it. The laser 551 is used to position the workpiece, and then laser engraving is performed on the workpiece. After laser engraving, the workpiece is transferred to the pallet by the unloading component 7. Then, the first lifting plate 48 falls and drives the pallet onto the conveying guide rail 41. The pallet is then conveyed to the third partition plate 410 by the conveying guide rail 41. When the pallet passes the second lifting plate 413, the fourth partition plate 414 blocks the pallet. The second lifting plate 413 drives the empty pallet to rise. The laser-engraved workpiece is then transferred to the empty pallet by the transfer component 8. The pallet is then conveyed to the end by the conveying guide rail 41. Finally, the transfer component 8 transfers the pallet to the unloading table 3, thus completing the laser engraving process of the workpiece. The operation is simple and convenient.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
