Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber laser marking, and in particular relates to an optical fiber laser marking machine which is easy to adjust. Background Art

[0002] In modern industrial production, laser marking technology has been widely used due to its advantages such as high precision, high speed and non-contact. As an advanced laser marking equipment, it plays an important role in many fields.

[0003] However, with the continuous changes in market demand and the diversification of products, the adaptability requirements for laser marking machines have increased. When facing irregularly shaped workpieces, it may be inconvenient to adjust the multiple angles of the fixed workpiece, making it difficult for the laser beam to irradiate the workpiece surface from the appropriate angle, resulting in poor marking effects, and thus problems such as unclear handwriting and pattern deformation.

[0004] In order to solve the above problems, this application proposes an optical fiber laser marking machine that is easy to adjust. Utility Model Content

[0005] In response to the problems in the related art, the utility model proposes an optical fiber laser marking machine that is easy to adjust to overcome the above technical problems existing in the existing related art.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A fiber laser marking machine that is easy to adjust includes a housing and a support platform located inside the housing, a support structure is provided at the bottom center of the support platform, a transmission structure is provided between the housing and the support platform, a marker is fixedly connected to the top of the housing, a clamping structure is provided on the top of the support platform, and a baffle is fixedly connected to the top of the support platform;

[0008] The transmission structure includes a motor fixedly connected to the top of the shell, the output end of the motor is fixedly connected to a threaded rod, the outer wall of the threaded rod is threadedly connected to a threaded sleeve, the top of the threaded sleeve is hinged to a connecting rod, the top of the connecting rod is fixedly connected to a second rolling ball, the outer wall of the second rolling ball is rollingly connected to the second rolling sleeve, and the top of the second rolling sleeve is fixedly connected to the bottom of the support platform.

[0010] The top of the second moving plate is fixedly connected to the top of the support platform, and the second moving plate and the top of the first moving plate are respectively fixedly connected to the limiting column by arranging the cylinder, the first moving plate, the first linkage rod, the transmission plate, the second linkage rod, the second moving plate and the limiting column, so as to fix the workpiece to be marked, thereby preventing movement due to external force during the marking process.

[0011] Preferably, a through hole is opened at the top of the baffle, and the limiting column is slidably connected to the baffle through the through hole. By setting the limiting column, baffle and through hole, the workpiece to be marked is separated from the parts under the baffle, avoiding direct contact between the workpiece and the parts, and reducing the risk of damage to the objects and parts.

[0012] Preferably, the outer side wall of the limiting column is fixedly connected to a rubber pad, and the surface of the rubber pad is provided with textures.

By arranging the first fixed block, the spring and the second fixed block, a buffering effect is achieved, thereby reducing damage to the device.

[0014] To sum up, the technical effects and advantages of the utility model are as follows: the optical fiber laser marking machine which is easy to adjust provides support for the support table through the coordinated use of the support structure and the support table; through the operation of the motor, the coordination and use of the threaded rod and the threaded sleeve, the threaded sleeve drives the connecting rod to move in the vertical direction; through the coordinated use of the second rolling ball and the second rolling sleeve, when the second rolling sleeve drives the support table to move, the influence of the angle between the connecting rod and the support table on the second rolling ball is reduced, thereby facilitating the staff to adjust the angle of the support table so that the laser beam is irradiated on the workpiece at a suitable angle, avoiding blurred marking due to angle deviation.

[0015] Through the operation of the cylinder, the first movable plate and the first linkage rod are used in conjunction with each other to make the transmission plate rotate, and the transmission plate and the second linkage rod are used in conjunction with each other to make the second movable plate move. Through the cooperation of the first movable plate and the first linkage rod, the limit column clamps the workpiece above the baffle to avoid movement due to external force during the marking process.

[0030] When in use, the workpiece is placed on the top of the baffle 7. Since the support structure 3 is located at the bottom center of the support platform 2, when the support platform 2 rotates, the support platform 2 rotates with the support structure 3 as the support point, and the two motors 401 are started at the same time. The two threaded rods 402 respectively drive the threaded sleeves 403 to move, and then the two connecting rods 404 respectively drive the second rolling balls 405 to move. Since the two second rolling balls 405 are respectively inside the second rolling sleeves 406, and the two second rolling balls 405 are respectively connected to the second rolling sleeves 406 in a rolling manner, the two second rolling sleeves 406 both drive the support platform 2 to move on the side close to the second rolling sleeve 406, so that by adjusting the angle of the support platform 2, the angle of the baffle 7 changes with the support platform 2.

[0031] Reference Figure 4The support structure 3 includes a support rod 301 fixedly connected to the top of the shell 1, and a first rolling ball 302 is fixedly connected to the top of the support rod 301. The first rolling ball 302 is located at the top center of the support rod 301, and the first rolling ball 302 is rollingly connected to the first rolling sleeve 303.

The top of the first rolling sleeve 303 is fixedly connected to the bottom of the support platform 2, and the first rolling sleeve 303 is located at the bottom center of the support platform 2. The first rolling sleeve 303 is rollingly connected to the first rolling ball 302, so that the support structure 3 provides support for the support platform 2 while the support platform 2 rotates around the first rolling ball 302 as the center.

[0032] Reference Figure 3 The clamping structure 6 includes a cylinder 601 fixedly connected to the top of the support platform 2, the telescopic end of the cylinder 601 is fixedly connected to the first movable plate 602, the bottom of the first movable plate 602 is slidably connected to the top of the support platform 2, the first movable plate 602 is located on the left side of the top of the support platform 2, the outer wall of the first movable plate 602 is hinged with a first linkage rod 603, the end of the first linkage rod 603 away from the first movable plate 602 is hinged with a transmission plate 604, the center of the transmission plate 604 is rotatably connected to the top of the support platform 2, and the center point of the transmission plate 604 and the support platform 2 is located at the same A straight line, the end of the transmission plate 604 away from the first linkage rod 603 is hinged to the second linkage rod 605, and the end of the second linkage rod 605 away from the transmission plate 604 is hinged to the second movable plate 606. The bottom of the second movable plate 606 is slidably connected to the top of the support platform 2. The second movable plate 606 is located on the top right side of the support platform 2, and the first movable plate 602, the transmission plate 604 and the second movable plate 606 are located in the same horizontal plane. The tops of the second movable plate 606 and the first movable plate 602 are respectively fixedly connected to the limiting columns 607, and there are four limiting columns 607.

[0033] When in use, the cylinder 601 is operated, and the cylinder 601 drives the first movable plate 602 to move, so that the first movable plate 602 pushes the first linkage rod 603 to move, and then the first linkage rod 603 pushes one end of the transmission plate 604 to move. Since the center of the transmission plate 604 is rotatably connected to the top of the support platform 2, the transmission plate 604 moves in the opposite direction away from one end of the first linkage rod 603, so that the second linkage rod 605 follows the transmission plate 604 to move away from one end of the first linkage rod 603, thereby causing the second movable plate 606 and the first movable plate 602 to move inward. Since two limiting columns 607 are fixedly installed on the top of the second movable plate 606 and the first movable plate 602 respectively, the four limiting columns 607 will move inward, thereby clamping the workpiece.

[0034] Reference Figure 3A through-hole 8 is provided at the top of the baffle 7. There are two through-holes 8, which are located on both sides of the top of the baffle 7. The four limiting columns 607 are slidably connected to the baffle 7 through the two through-holes 8, thereby isolating the workpiece from the parts under the baffle 7 to avoid direct contact between the workpiece and the parts.

[0035] Reference Figure 3 The outer walls of the four limiting columns 607 are fixedly connected with rubber pads 608. There are four rubber pads 608, and the surfaces of the four rubber pads 608 are provided with textures, so as to increase the friction between the limiting columns 607 and the workpiece, and prevent the workpiece from falling off during the marking process.

[0036] Reference Figure 2 The top of the shell 1 is fixedly connected to a first fixed block 9, and there are two first fixed blocks 9. The two first fixed blocks 9 are located on the left side inside the shell 1. The tops of the two first fixed blocks 9 are fixedly connected to a spring 10, and there are two springs 10. The tops of the two springs 10 are fixedly connected to a second fixed block 11, and there are two second fixed blocks 11. The tops of the two second fixed blocks 11 are fixedly connected to the bottom of the support platform 2. The two springs 10 pull the shell 1 and the support platform 2 respectively, thereby playing a buffering role on the support platform 2 and reducing damage to the device.

[0037] Working principle: Place the workpiece on the top of the baffle 7, operate the cylinder 601, the cylinder 601 drives the first movable plate 602 to move, so that the first movable plate 602 pushes the first linkage rod 603 to move, and then the first linkage rod 603 pushes one end of the transmission plate 604 to move. Since the center of the transmission plate 604 is rotatably connected to the top of the support platform 2, the transmission plate 604 moves in the opposite direction away from the end of the first linkage rod 603, so that the second linkage rod 605 follows the transmission plate 604 to move away from the end of the first linkage rod 603, and then the second movable plate 606 and the first movable plate 602 move toward the direction close to the transmission plate 604, and the four limit columns 607 move toward the direction close to the transmission plate 604, thereby clamping the workpiece, and at the same time starting the two A motor 401 and two threaded rods 402 respectively drive the threaded sleeve 403 to move, and then the two connecting rods 404 respectively drive the second rolling ball 405 to move. Since the two second rolling balls 405 are respectively inside the second rolling sleeve 406, and the two second rolling balls 405 are respectively connected to the second rolling sleeve 406 in a rolling manner, the two second rolling sleeves 406 both drive the support platform 2 to move on the side close to the second rolling sleeve 406. Since the support structure 3 is located at the bottom center of the support platform 2, when the horizontal angle of the support platform 2 changes, the support platform 2 rotates with the support structure 3 as the support point, so that by adjusting the angle of the support platform 2, the angle of the baffle 7 changes along with the support platform 2, so that the laser beam is irradiated on the workpiece at a suitable angle.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
