Description

Technical Field

[0001] This utility model relates to the field of fiber laser marking machine technology, specifically a high-precision fiber laser marking machine. Background Technology

[0002] A fiber laser marking machine is a device that uses laser technology to mark, engrave, or print. It uses a fiber laser as the laser source, focusing a high-energy laser beam into a very small area. By controlling the position and intensity of the laser beam, permanent scratches or marks are created on the material surface. These scratches or marks can be text, patterns, or barcodes.

[0003] For example, utility model patent CN221110305U discloses a high-precision fiber laser marking machine. Its technical solution includes: a worktable, a motor, and a rotating structure. The rear end of the worktable is movably connected to the fiber laser marking machine body. A support frame is fixed to the worktable. A groove is formed at the front end of the support frame. Rotary shafts are rotatably connected to both sides of the inner wall of the groove. A motor is fixed to the upper end of one side of the support frame. A transmission shaft of the motor is rotatably connected to the rotating structure. A rotating shaft is fixed to one side of the transmission shaft of the motor. A second support frame is fixed to one side of the rotating shaft. A groove is formed in the second support frame. Slots are formed at both the front and rear ends of the second support frame. Long grooves are formed at both the front and rear ends of the inner wall of the groove. This utility model has the advantage of allowing the workpiece to be rotated in a limited manner as needed, which facilitates marking on both sides of the workpiece, saving time and effort and improving work efficiency. However, there is still a problem that the workpiece still needs to be manually picked up before and after marking, which will waste a certain amount of time in the process of picking up the workpiece, and ultimately reduce the marking efficiency of the workpiece and the overall work efficiency. To address this, we propose a high-precision fiber laser marking machine. Utility Model Content

[0006] Preferably, the inner end of the C-shaped plate is fixedly connected to two symmetrically arranged guide rails, and each of the two guide rails has a guide groove at one end close to each other. A movable column is slidably connected to the inner wall of the guide groove, and an L-shaped movable plate is fixedly connected to one end of each of the two movable columns close to each other.

[0007] Preferably, the rotation limiting assembly includes a second stepper motor fixedly connected to the middle of the right side of the worktable, a first rotating shaft fixedly connected to the output end of the second stepper motor, a U-shaped rotating sleeve fixedly connected to the end of the first rotating shaft away from the second stepper motor, second electric push rods fixedly connected to both the front and rear ends of the U-shaped rotating sleeve, the output ends of the second electric push rods slidably connected to the U-shaped rotating sleeve, clamping plates fixedly connected to the ends of the two second electric push rods close to each other, and a second rotating shaft fixedly connected to the end of the U-shaped rotating sleeve away from the first rotating shaft.

[0008] Preferably, the support assembly includes a first electric push rod fixedly connected to the workbench, and two first electric push rods are fixedly connected to a support plate at one end close to each other, with the outer end of the support plate slidably connected to a first sliding groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Equipped with a worktable, support columns, placement groove, first chute, drop chute, conveyor belt, and workpiece top clamping assembly, this device enables the horizontal adjustment of workpieces conveyed to the placement groove via the conveyor belt. An external power supply can power the first stepper motor, which in turn drives a rotating rod. This rotating rod then drives a moving block to slide within the second chute. The moving block, in turn, moves a fixed plate, spring, limit plate, guide column, L-shaped moving plate, and clamping sponge backward. During this process, the L-shaped moving plate... The moving column slides within the guide groove. Due to the shape of the guide rail, the moving column drives the L-shaped moving plate downwards, which in turn drives the guide column and the limiting plate downwards. At this time, the limiting plate compresses the spring. When the pressing sponge continuously presses the workpiece placed in the placement groove, the workpiece is adjusted to a horizontal state. This utility model realizes the automatic placement of workpieces onto the worktable for marking, and can press the top of skewed workpieces on the worktable to make them stable, thus improving the working efficiency of the device and saving time and effort.

[0016] 2. Equipped with a rotation limit component and a marking device, the workpiece, conveyed by a conveyor belt to the placement slot, is placed inside the U-shaped rotating sleeve. Then, an external power source powers the second electric push rod, whose output drives the clamping plate to clamp the workpiece. When marking is required on the other side of the workpiece, an external power source powers the second stepper motor. The second stepper motor's output drives the first rotating shaft to rotate, which in turn rotates the U-shaped rotating sleeve. The U-shaped rotating sleeve then drives the second rotating shaft to rotate, directly causing the workpiece to flip over, thus improving the device's convenience.

[0017] 3. The device is equipped with a support assembly. When the workpiece moves into the placement slot, the support plate supports the workpiece. After both the upper and lower surfaces of the workpiece have completed the required actions, the first electric push rod can be powered by an external power source. The output end of the first electric push rod drives the support plate to move back. The support plate then slides in the first chute. During this process, the support plate no longer supports the workpiece, and the workpiece falls directly into the drop chute for discharge, improving the convenience of the device.

A limit plate 89 is fixedly connected to the upper end of the spring 88. A guide post 810 is fixedly connected to the end of the limit plate 89 near the spring 88. An L-shaped moving plate 811 is fixedly connected to the lower end of the guide post 810. A compression sponge 812 is fixedly connected to the lower end of the L-shaped moving plate 811.

[0027] In this embodiment, two symmetrically arranged guide rails 813 are fixedly connected to the inner end of the C-shaped plate 81. Each of the two guide rails 813 has a guide groove 814 at one end close to each other. A movable column 815 is slidably connected to the inner wall of the guide groove 814. An L-shaped movable plate 811 is fixedly connected to one end of each of the two movable columns 815 at one end close to each other.

[0028] Specifically, the L-shaped moving plate 811 drives the moving column 815 to slide within the guide groove 814, thereby achieving the guiding and limiting action of the L-shaped moving plate 811.

[0029] In this embodiment, the rotation limiting component 9 includes a second stepper motor 91 fixedly connected to the middle of the right side of the workbench 1. The output end of the second stepper motor 91 is fixedly connected to a first rotating shaft 92. The end of the first rotating shaft 92 away from the second stepper motor 91 is fixedly connected to a U-shaped rotating sleeve 93.

[0030] Specifically, the workpiece conveyed to the placement slot 3 by the conveyor belt 7 and the marking device 10 is placed in the rotary sleeve 93. Then, the second electric push rod 95 can be powered by an external power source. At this time, the output end of the second electric push rod 95 drives the clamping plate 96 to clamp the workpiece. When it is necessary to mark the other side of the workpiece, the second stepper motor 91 can be powered by an external power source. At this time, the output end of the second stepper motor 91 drives the first rotating shaft 92 to rotate, which in turn drives the rotary sleeve 93 to rotate. The rotary sleeve 93 drives the second rotating shaft 94 to rotate, which directly drives the workpiece to flip over, improving the convenience of the device.

[0031] In this embodiment, the support component 6 includes a first electric push rod 61 fixedly connected to the workbench 1. Two first electric push rods 61 are fixedly connected to a support plate 62 at one end close to each other. The outer end of the support plate 62 is slidably connected to a first slide groove 4.

[0032] Specifically, the support assembly 6 can support the workpiece when it moves into the placement groove 3. Once the workpiece has been properly supported on both sides, the first electric push rod 61 can be powered by an external power source. The output of the first electric push rod 61 then drives the support plate 62 to move back. The support plate 62 then slides in the first chute 4. During this process, the support plate 62 no longer supports the workpiece, and the workpiece falls directly into the drop chute 5 for discharge, improving the convenience of the device.

[0033] In this embodiment, both the first rotating shaft 92 and the second rotating shaft 94 are rotatably connected to the worktable 1 via bearings.

[0034] Specifically, ensure that the first rotating shaft 92 and the second rotating shaft 94 do not interfere with the worktable 1 during rotation.

[0035] In this embodiment, the outer end of the rotating rod 85 is provided with a threaded groove, and the end of the rotating rod 85 away from the first stepper motor 84 is rotatably connected to the placement bar 82 through a bearing.

[0036] Specifically, ensure that the rotating rod 85 does not interfere with the placement strip 82 during rotation.

[0037] In this embodiment, the outer end of the guide post 810 is slidably connected to the fixing plate 87, and the guide post 810 passes through the fixing plate 87.

[0038] Specifically, ensure that the guide post 810 can slide normally.

[0039] In this embodiment, the left end of the guide rail 813 is set in a horizontal state, and the right end of the guide rail 813 is set in a downward-sloping arc shape.

[0040] Specifically, ensure that the moving column 815 drives the L-shaped moving plate 811 to move horizontally first and then diagonally downward during the movement process.

[0041] In this embodiment, each corner of the lower end of the workbench 1 is fixedly connected with a support column 2, and the lower end of each support column 2 is treated with anti-slip treatment.

[0042] Specifically, the stability of the workbench 1 during operation can be improved by using the support column 2.

[0043] Working principle: The workpiece is conveyed to the placement groove 3 by the conveyor belt 7 for horizontal adjustment. At this time, the first stepper motor 84 can be powered by an external power source. The output end of the first stepper motor 84 drives the rotating rod 85 to rotate. The rotating rod 85 drives the moving block 86 to slide in the second slide groove 83. The moving block 86 drives the fixed plate 87, spring 88, limit plate 89, guide post 810, L-shaped moving plate 811 and pressing sponge 812 to move backward. During this process, the L-shaped moving plate 811 drives... The movable column 815 slides within the guide groove 814. Due to the shape of the guide rail 813, the movable column 815 drives the L-shaped movable plate 811 to move downwards, which in turn drives the guide column 810 and the limiting plate 89 to move downwards. At this time, the limiting plate 89 compresses the spring 88. When the clamping sponge 812 continuously clamps the workpiece placed in the placement groove 3, the workpiece is adjusted to a horizontal state. Next, the second electric push rod 95 is powered by an external power source, and the output end of the second electric push rod 95 drives the clamping mechanism. The plate 96 clamps the workpiece. When marking is required on the other side of the workpiece, the second stepper motor 91 can be powered by an external power source. The output of the second stepper motor 91 drives the first rotating shaft 92 to rotate, which in turn drives the rotary sleeve 93 to rotate. The rotary sleeve 93 then drives the second rotating shaft 94 to rotate, directly causing the workpiece to flip. Once both sides of the workpiece have been marked, the first electric push rod 61 can be powered by an external power source. The output end drives the support plate 62 to move back and forth. At this time, the support plate 62 slides in the first slide groove 4. During this process, the support plate 62 no longer supports the workpiece. The workpiece falls directly into the falling inclined groove 5 for discharge. In the whole process, the marking device 10 can mark both sides of the workpiece. This utility model realizes that the workpiece can be automatically placed on the worktable 1 for marking. It can also press the top of the tilted workpiece that has been moved to the worktable 1 to make it stable, which improves the working efficiency of the device and saves time and effort.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
