Description

Technical Field

[0001] This application relates to the field of laser marking technology, and in particular to a pushing mechanism for laser marking. Background Technology

[0002] Laser marking is a technology that uses a high-energy-density laser beam to form permanent marks on the surface of various materials through burning, etching, or phase transition. It can mark information such as text, patterns, QR codes, and serial numbers. It features clear marking, high speed, no pollution, and strong wear resistance. Its application scenarios cover a variety of materials such as metals, plastics, glass, and ceramics.

[0003] Chinese Patent No. CN222696275U discloses a pushing mechanism for laser marking, including a base. A rotating sleeve is fixedly connected to the top of the base, and a cylindrical block is rotatably connected to the top of the rotating sleeve. A work frame is fixedly connected to the top of the cylindrical block, and two symmetrically distributed storage slots are provided on the top of the work frame. A positioning mechanism is provided on the work frame. The positioning mechanism includes two pressure plates disposed within the work frame, and multiple L-shaped positioning rods are fixedly connected to the top of each pressure plate. One end of each L-shaped positioning rod slides into the corresponding storage slot. This utility model relates to the field of laser marking technology. This pushing mechanism for laser marking, through the positioning mechanism, can clamp the object to be processed placed in the storage slot, centering it in the storage slot for easy laser marking. This results in a more aesthetically pleasing and better marking effect, with the label positioned in the center of the object to be processed.

[0004] However, when marking objects in the above-mentioned patent, it is necessary to use a positioning mechanism to position and clamp the objects inside the storage slot before marking can be performed. This marking method makes it difficult to continuously push and feed the hardware, and the objects need to be frequently loaded, unloaded, and clamped, thus reducing the laser marking speed of the objects. Therefore, in order to solve the above problems, we provide a pushing mechanism for laser marking. Summary of the Invention

[0005] The purpose of this utility model is to provide a pushing mechanism for laser marking, so as to solve the problem mentioned above. In the current technology, when marking objects, it is necessary to use a positioning mechanism to position and clamp the objects inside the storage slot before marking can be performed. However, this marking method is difficult to continuously push and feed the hardware, and the objects need to be frequently loaded, unloaded and clamped, thus reducing the laser marking speed of the objects.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1

[0018] As attached Figures 1-5 The illustrated laser marking pushing mechanism includes a pushing platform 1. An adjustment mechanism 2 is fixedly installed on the bottom surface of the pushing platform 1. A reciprocating drive mechanism 8 is located below the pushing platform 1. Support plates 3 are fixedly installed on both sides of the pushing platform 1. A support top plate 4 is fixedly connected to the upper surface of the support plates 3. An electric cylinder 5 is fixedly installed on the upper surface of the support top plate 4. A laser marking device 7 is fixedly installed at the telescopic end of the electric cylinder 5. The laser marking device 7 includes a laser generator, an optical lens group, and a control module. The generator produces a high-energy laser, which is focused by the lens... The laser marking device 7 is positioned above the push platform 1. A limit baffle 6 is installed above the push platform 1, and a push plate 9 is installed above the push platform 1. The push platform 1 serves as a support base and can support the object. Through the adjustment mechanism 2 and the reciprocating drive mechanism 8, the object can be reciprocated and pushed for feeding. With the electric cylinder 5, the laser marking device 7 can operate above the push platform 1, and together with the limit baffle 6 and the push plate 9, the material is limited and fed. Example 2

[0019] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail: The reciprocating drive mechanism 8 includes a drive motor 81 fixedly mounted on the bottom surface of the pusher table 1, a drive shaft 86 fixedly mounted on the output end of the drive motor 81, a drive disk 82 fixedly mounted on the bottom end of the drive shaft 86, a transmission plate 83 hinged to the bottom surface of the drive disk 82 via a pin, a transmission block 84 hinged to the upper surface of the transmission plate 83 via a pin, and the upper surface of the transmission block 84 fixedly connected to the bottom surface of the pusher plate 9. The drive motor 81 outputs power and transmits it to the drive disk 82 via the drive shaft 86. The drive disk 82 pulls the transmission plate 83 to reciprocate through the pin, and then the transmission block 84 transmits the power to the pusher plate 9, thus realizing the material pushing function. It can convert rotary motion into linear reciprocating motion through mechanical linkage, and can provide stable power for continuous material conveying.

[0020] The adjustment mechanism 2 includes an adjustment slide 21 fixedly mounted on the bottom surface of the push platform 1. A double-headed motor 22 is fixedly mounted on the inner wall of the adjustment slide 21. A transmission screw 25 is fixedly mounted on each of the two output ends of the double-headed motor 22. A threaded slide plate 24 is threadedly connected to the outer surface of the transmission screw 25. The upper surface of the threaded slide plate 24 is fixedly connected to the bottom surface of the limit baffle 6. A bearing seat 23 is fixedly mounted on the inner wall of the adjustment slide 21. The inner ring of the bearing seat 23 is fixedly connected to the outer surface of the transmission screw 25. A bearing plate 85 is fixedly mounted on the inner wall of the adjustment slide 21. The inner ring of the bearing plate 85 is fixedly connected to the outer surface of the drive shaft 86. The double-headed motor 22 drives the two transmission screws 25 to rotate, which enables the threaded slide plate 24 to drive the limit baffle 6 to adjust the spacing. The bearing seat 23 ensures the stable rotation of the transmission screw 25, and the bearing plate 85 ensures the coaxiality of the drive shaft 86. Bearings are installed inside both the bearing seat 23 and the bearing plate 85. The bearing components improve the smoothness of the mechanism's operation.

[0021] The upper surface of the pusher table 1 is provided with a sliding hole 11. The outer surface of the pusher plate 9 is slidably connected to the inner wall of the sliding hole 11. Two sets of support bases 10 are fixedly connected to the bottom surface of the pusher table 1. The bottom surface of the support top plate 4 is provided with a limit hole 12. The side of the laser marking device 7 is equipped with a limit slide plate 13. The top of the limit slide plate 13 passes through the limit hole 12 and extends above the limit hole 12. The outer surface of the limit slide plate 13 is slidably connected to the inner wall of the limit hole 12. The sliding hole 11 of the pusher table 1 can provide sliding guidance for the pusher plate 9. The support base 10 ensures the overall stability. The limit hole 12 of the support top plate 4 cooperates with the limit slide plate 13 of the laser marking device 7 to enable the laser marking device 7 to move up and down stably.

[0022] The working principle of this utility model is as follows: First, the material limiting and matching is completed by the adjustment mechanism 2. The start of the double-head motor 22 can drive the transmission screws 25 at the two output ends to rotate, and the threaded slide plate 24 will move along the axial direction of the transmission screw 25, thereby driving the limiting baffle 6 to adjust the spacing until it matches the size of the object to be marked. Then, the reciprocating drive mechanism 8 is started, and the drive motor 81 outputs power, which drives the drive disk 82 to rotate through the drive shaft 86. The drive disk 82 pulls the transmission plate 83 to perform reciprocating push-pull motion through the pin shaft. The transmission plate 83 then drives the push plate 9 to slide along the sliding hole 11 of the push table 1 through the transmission block 84, which can smoothly push the object to be marked to the bottom of the laser marking machine 7.

[0023] Once the object reaches the designated position, the laser marking device 7 marks the object with a laser. The extension movement of the electric cylinder 5 can drive the laser marking device 7 to move up and down, making it easy to adjust the marking height and suitable for marking objects of different thicknesses. At the same time, the reciprocating drive mechanism 8 continues to work, and the push plate 9 will return to the initial position to receive the next object to be marked, realizing continuous cyclic marking. The whole process does not require frequent manual loading and unloading and clamping operations.

[0024] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail. In addition, the power supply module, circuit, electronic components and control module involved in this utility model are all existing technologies and can be fully implemented by those skilled in the art. There is no need to elaborate. The content protected by this utility model does not involve any improvement to the internal structure and method.
