Description

Technical Field

[0001] This utility model relates to the field of marking device technology, and in particular to a highly automated lamp cup laser marking machine. Background Technology

[0002] Laser marking machines generate a laser beam through a laser oscillator. After amplification and focusing, the laser beam can remove material and etch marks on the surface of a workpiece. It features high precision, high efficiency, and environmental friendliness, and is widely used in various industries. In current technology, when laser marking machines process scales and patterns on the surface of pipes, the pipes first need to be manually clamped onto a fixture. After alignment, the laser processing head is started to automatically process the pipe surface. After processing, the pipe on the fixture needs to be removed, and other pipes to be processed need to be placed in, clamped and aligned, and then the laser processing head is started to automatically feed the process. A series of operations are required; moreover, for pipes of different diameters, the distance between their surface and the laser processing head is different after the clamping fixture holds them. The surface of pipes with larger diameters is closer to the laser processing head than that of pipes with smaller diameters. Marking machines are different from cutting machines, and the relative distance and focal length between the laser head and the workpiece surface are more precise to avoid piercing the pipe. Therefore, it is necessary to adjust the position and focal length of the processing head to make the distance between the pipe surface and the laser processing head appropriate. This not only makes the operation cumbersome and reduces efficiency, but also the frequent clamping and alignment are prone to errors, resulting in defective products, reducing product quality and increasing costs. Utility Model Content

[0003] The purpose of this invention is to provide a highly automated laser marking machine for lamp cups to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A highly automated laser marking machine for lamp cups includes a laser marking machine and a feeding device. The laser marking machine is disposed on one side of the feeding device. The feeding device includes a worktable, a support frame at the bottom of the worktable, and a drive device fixedly mounted at the center of the bottom of the worktable. The output shaft of the drive device passes through the worktable and extends to the top of the worktable. A turntable is disposed at the center of the top of the worktable, and the turntable is fitted onto the output shaft.

[0019] Example 1:

[0020] like Figures 1-2As shown, a highly automated laser marking machine for lamp cups includes a laser marking machine 1 and a feeding device 2. The laser marking machine 1 is located on one side of the feeding device 2. The feeding device 2 includes a worktable 3, with a support frame 4 at the bottom of the worktable 3. A drive device 5 is fixedly installed at the center of the bottom of the worktable 3. The output shaft of the drive device 5 passes through the worktable 3 and extends to the top of the worktable 3. A turntable 6 is located at the center of the top of the worktable 3. The turntable 6 is fitted onto the output shaft. Multiple mounting holes are evenly arranged axially around the top periphery of the turntable 6. The mounting holes are through holes that extend vertically. A bearing 7 is rotatably installed inside the mounting holes. A cup holder is fixedly installed on the top of the inner ring of the bearing 7, and a cup holder is fixedly installed on the bottom of the inner ring of the bearing 7. The worktable has a locking block 8, a crossbeam 9 at the top of the support frame 4, a servo motor 10 fixedly installed at the bottom of the middle position of the crossbeam 9, a rectangular block 11 sleeved on the rotating shaft of the servo motor 10, and a horizontal through hole at the top of the rectangular block 11. The top of the worktable has an annular groove coaxial with the turntable, which runs vertically through the worktable and is used to avoid the rotation path of the locking block at the bottom of the bearing. The servo motor 10 drives the locking block 8 to rotate by connecting the rectangular block 11 with the locking block 8. A contact switch 12 is fixedly installed in the through hole of the rectangular block 11. The contact switch 12 is used to detect whether the locking block 8 is in the through hole. The bottom of the worktable 3 has a double limit switch, which is set correspondingly to the rectangular block 11. The double limit switch is used to limit the rotation angle of the rectangular block 11. An infrared detection sensor is set at the top of the laser marking machine 1, and a reflector corresponding to the infrared detection sensor is set at the top of the cup holder. A robotic arm is set on one side of the worktable 3, and storage racks and storage boxes are set on both sides of the robotic arm. A dust collection pipe is set at the top of the laser marking machine 1, and a suction nozzle is set at one end of the dust collection pipe. Because there is a vaporization process of material surface oxidation during the marking process, the dust collection pipe needs to suck the vaporized material to a special processing equipment for processing.

[0021] The drive unit controls the turntable 6 to rotate. Each time it rotates, a different card block enters or exits the through hole at the top of the rectangular block once. When the card block leaves, the contact switch 12 recognizes a signal. When another card block enters, the contact switch is triggered again, instructing the servo motor to quickly rotate a certain angle (here, it needs to be 90 degrees) and then slowly rotate back. During the slow rotation, the marking machine marks the lamp cup located in the cup holder, and the process repeats continuously.

[0022] Specific implementation process: The turntable can be rotated by the drive device. The setting of servo motor, rectangular block, bearing and clamp block can realize the rotation of the inner ring of the bearing, thereby realizing the rotation and revolution of the material on the turntable, which facilitates the rotation and marking of the material and realizes the purpose of marking automation.

[0023] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
