Description

Technical Field

[0001] The present invention relates to the technical field of laser marking, and in particular to a laser device with automatic loading and unloading functions. Background Art

[0002] Laser marking machines use laser beams to imprint permanent marks on various surfaces in seconds. The effect of marking is to expose the underlying material through evaporation of the surface layer, thereby creating intricate designs, trademarks, and text. Laser marking is often required in the processing of some fabrics. The existing technology involves manually placing the materials one by one, laser marking, and manually changing the products to meet the required standards. The disadvantages of this marking method are that it wastes manpower and has poor safety and reliability. Manual placement can easily lead to inaccurate placement, resulting in skewed icons or text, making the product unusable. Furthermore, manual labor is inefficient and costly, hindering the improvement of product value. Summary of the Invention

[0003] In view of this, the present invention provides a laser device with automatic loading and unloading functions to solve the above technical problems.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A laser device with automatic loading and unloading functions includes a frame, on which a laser machine, a host and a laser chamber are provided. The host is used to control the laser machine. The laser machine is located above the laser chamber. The laser chamber includes a loading box, a laser table, a material receiving box and a material transfer device. The laser table is located directly below the laser machine. The material transfer device includes a movable guide rail, a material taking module and a material receiving module. The movable guide rail is movably connected to the laser chamber. One of the material taking module and the material receiving module is fixed on the movable guide rail, and the other is slidably connected to the movable guide rail and is driven by a variable pitch cylinder fixed on the movable guide rail. The movable guide rail moves laterally relative to the laser chamber, and the material taking module and the material receiving module can move vertically. The movable guide rail of the laser device of the present invention moves laterally in the laser chamber to control the lateral movement of the material and realize the movement of the material before and after marking. The material picking module and the material receiving module are used to adsorb or clamp the material; in addition, the material picking module and the material receiving module of the present invention have both commonly moving parts and relatively moving parts when moving, that is, common movement is achieved through the movable guide rail, and relative movement is achieved through the variable pitch cylinder, which makes the transfer of materials more flexible and changeable. The moving stroke of the movable guide rail can be effectively saved in the process of picking, laser marking and receiving, and the marking efficiency is significantly improved while realizing automation.

[0006] Furthermore, the retrieving and receiving modules share the same structure, each comprising a fixed frame, a movable plate, a drive cylinder, and a suction tray. The movable plate is slidably connected to the fixed frame, and the drive cylinder is fixed to the fixed frame and is used to drive the movement of the movable plate. The suction tray is located at the end of the movable plate away from the drive cylinder. The drive cylinder indirectly drives the vertical movement of the suction tray relative to the laser chamber via the movable plate, allowing the suction tray to contact the material. The fixed plate of the retrieving module is fixed to a movable guide rail, while the fixed plate of the receiving module is slidably connected to the movable guide rail.

[0007] Furthermore, the two suction trays are connected by a connecting plate, which is rotatably connected to the movable plate via a rotating cylinder. When materials are delivered, release paper is usually placed between adjacent layers to prevent the laser samples from sticking together. Therefore, after one of the two suction trays absorbs the material, the other, driven by a rotating cylinder, removes the release paper, thereby achieving material processing.

[0008] Furthermore, an elastic buffer is provided between the connecting plate and the material suction disc. The elastic buffer provides a buffering effect when the material suction disc contacts the material during downward pressure. The pressure on the material increases gradually rather than suddenly, thus effectively protecting the integrity of the material and preventing it from being crushed by the material suction disc.

[0009] Furthermore, the laser chamber is fixedly provided with a rack, and the movable guide rail is connected to a drive module, which includes a motor and a gear fixedly connected to the motor shaft, and the gear and rack are meshed with each other. The rotation of the motor and gear is converted into the movement of the movable guide rail, thereby achieving the purpose of material transfer.

[0010] Furthermore, the laser table is provided with a positioning groove, which is provided with multiple air extraction holes, which are connected to an air pump. The positioning groove is used to place materials and ensure the accuracy of the laser machine's alignment. The air pump's suction action creates negative pressure within the air extraction holes, pressing the materials against the positioning grooves to prevent them from moving, further increasing the accuracy of the laser machine's alignment.

[0011] Furthermore, the laser chamber is equipped with a door and a sensor. When the door is closed, it blocks the sensor to trigger its sensing condition. To ensure the safety of the processing process, the sensor detects whether the door is closed. If it is confirmed to be closed, the device can start working; otherwise, the device is prohibited from starting.

[0012] Furthermore, the chamber door is a transparent door. The transparent door allows the processing process to be observed while ensuring safety, achieving real-time monitoring and further improving processing safety.

[0013] Furthermore, the laser room is also equipped with a PLC control module, which is electrically connected to the material transfer device and the host computer. The working route and work content of each component are determined by the program, making the processing smooth and automated.

[0014] Furthermore, the laser room is provided with a smoke extraction port, which is connected to an external air source and is used to extract waste gas generated by the laser marking machine and recycle it to avoid environmental pollution.

[0015] The beneficial effects of the present invention compared to the prior art are:

[0016] The present invention provides a laser device with automatic loading and unloading functions, which controls the movement of materials before and after laser marking by setting a material picking module and a material receiving module, thereby automating the material loading, laser marking and material receiving processes. The material picking module and the material receiving module can realize both common displacement and relative displacement. Therefore, the stroke of the moving guide rail will be reduced during the material transfer process, and the variable pitch cylinder can replace part of the stroke of the moving guide rail. Therefore, it is more flexible and adaptable to the processing of various types of materials. At the same time, it also shortens the overall time of loading and receiving, and improves the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] To facilitate understanding by those skilled in the art, the present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0023] Please refer to Figures 1-4 , a preferred embodiment of the present invention is.

[0024] like Figure 1 and Figure 2 As shown, a laser device with automatic loading and unloading functions includes a frame 1, on which a laser machine 2, a host 3 and a laser chamber 4 are arranged. The host 3 is used to control the laser machine 2. The laser machine 2 is located above the laser chamber 4. The laser chamber 4 includes a loading box 41, a laser table 42, a material receiving box 43 and a material transfer device 5. The laser table 42 is located directly below the laser machine 2. The material transfer device 5 includes a moving guide rail 51, a material taking module 52 and a material receiving module 53. The movable guide rail 51 is movably connected to the laser chamber 4, one of the material taking module 52 and the material receiving module 53 is fixed on the movable guide rail 51, and the other is slidably connected to the movable guide rail 51 and driven by the variable pitch cylinder 14 fixed on the movable guide rail 51; in this embodiment, the material taking module 52 is fixed on the movable guide rail 51, and the material receiving module 53 is slidably connected to the movable guide rail 51, the movable guide rail 51 moves laterally relative to the laser chamber 4, and the material taking module 52 and the material receiving module 53 can move vertically. The movable guide rail 51 of the laser device of the present invention moves laterally in the laser chamber 4, and is used to control the lateral movement of the material to realize the movement of the material before and after marking. The material picking module 52 and the material receiving module 53 are used to adsorb or clamp the material; in addition, the material picking module and the material receiving module of the present invention have both a common moving part and a relative moving part when moving, that is, the common movement is achieved through the movable guide rail 51, and the relative movement is achieved through the variable pitch cylinder 14, so that the transfer of materials is more flexible and changeable. The moving stroke of the movable guide rail 51 can be effectively saved in the process of picking, laser marking and receiving, and the marking efficiency is significantly improved while realizing automation.

[0025] like Figure 4 As shown, the material taking module 52 and the material receiving module 53 have the same structure, both including a fixed frame, a movable plate 522, a driving cylinder 523, and a material suction plate 524. The movable plate 522 is slidably connected to the fixed frame, the driving cylinder 523 is fixed to the fixed frame and is used to drive the movement of the movable plate 522, and the material suction plate 524 is located at the end of the movable plate 522 away from the driving cylinder 523. The driving cylinder 523 indirectly drives the material suction plate 524 to move vertically relative to the laser chamber 4 through the movable plate 522, so that the material suction plate 524 can contact the material. Specifically, the fixed plate 521 of the material taking module 52 is fixed to the movable guide rail 51, and the fixed plate 521 of the material receiving module 53 is slidably connected to the movable guide rail 51.

[0026] In this embodiment, two suction trays 524 are connected by a connecting plate 6, which is rotatably connected to the movable plate 522 via a rotary cylinder 7. When incoming materials are delivered, release paper is typically placed between adjacent layers to prevent the laser samples from sticking together. Therefore, after one of the two suction trays 524 absorbs the material, the other, driven by the rotary cylinder 7, removes the release paper, thereby enabling material processing.

[0027] like Figure 4 As shown, an elastic buffer 8 is provided between the connecting plate 6 and the suction disc 524. The provision of the elastic buffer 8 allows the suction disc 524 to provide a buffering process when it contacts the material during the downward pressing process. The pressure on the material increases gradually rather than suddenly, thus effectively protecting the integrity of the material and preventing it from being crushed by the suction disc 524.

[0028] like Figure 2 As shown, the laser chamber 4 is fixed with a rack 9, and the movable guide rail 51 is connected to a drive module 10. The drive module 10 includes a motor and a gear fixedly connected to the motor shaft. The gear and rack 9 are meshed with each other. The rotation of the motor and gear is converted into the movement of the movable guide rail 51, thereby achieving the purpose of material transfer.

[0029] like Figure 2 and Figure 3 As shown, the laser table 42 has a positioning slot 421 formed with a plurality of air extraction holes 422 connected to an air pump. The positioning slot 421 is used to position materials and ensure accurate alignment of the laser machine 2. The air pump creates negative pressure within the air extraction holes 422, pressing the materials against the positioning slot 421 and preventing them from shifting, further enhancing the alignment accuracy of the laser machine 2.

[0030] The laser chamber 4 is equipped with a door 12 and a sensor 11. When closed, the door 12 blocks the sensor 11, triggering its sensing condition. To ensure process safety, the sensor 11 detects whether the door 12 is closed. Only if it is confirmed closed can the device begin operation; otherwise, the device is prohibited from starting. The door 12 is transparent, ensuring safety while allowing for real-time monitoring of the process, further enhancing process safety.

[0031] The laser chamber 4 is equipped with a PLC control module 13, which is electrically connected to the material transfer device 5 and the main machine 3. Programs determine the working routes and tasks of each component, ensuring a smooth and automated processing. Furthermore, the laser chamber 4 is equipped with a smoke vent connected to an external air source. This vent is used to extract and recycle exhaust gases generated by the laser marking machine 2 after marking, preventing environmental pollution.

[0032] The working principle of the present invention is as follows: taking the material taking module 52 fixedly connected to the moving guide rail 51 and the material receiving module 53 slidingly connected to the moving guide rail 51 as an example, before starting the device, add enough materials to the loading box 41. After starting the device, the driving cylinder 523 of the material taking module 52 drives the suction plate 524 to press down to absorb the material and then lift it up. The rotary cylinder 7 is started, and the other suction plate 524 performs the same action to suck up the isolation paper. Then, the moving guide rail 51 is driven by the driving module 10 to move the material taking module 52 to the top of the laser table 42, and the driving cylinder 523 is pressed down to place the material on the laser table. The laser marking machine 20 is moved to the groove of the shooting table 42, and the air pump is turned on to extract the air to press the material onto the laser table 42. Then the material picking assembly returns to the top of the loading box 41 to pick up the material again. At this time, the variable pitch cylinder 14 works to push the receiving module 53 away to prevent the laser laser machine 2 from irradiating the receiving module 53. After the laser is completed, the receiving module 53 returns to the top of the laser table 42 to recycle the material. At this time, the receiving module 52 has picked up the material again, and the receiving module 53 has absorbed the marked material. The moving guide rail 51 moves the newly picked up material to the laser table 42, and moves the qualified material to the receiving box 43, thereby completing a marking cycle.

[0033] Although the present invention has been described with reference to the above specific embodiments, it will be apparent to those skilled in the art that many substitutions, modifications, and variations can be made based on the above. Therefore, all such substitutions, modifications, and variations are intended to be encompassed within the spirit and scope of the appended claims.
