Description

Technical Field

[0001] The present application relates to the field of jewelry processing, and in particular to a laser jewelry engraving machine. Background Art

[0002] In the field of jewelry processing, although traditional laser cutting equipment can perform processing to a certain extent, it can usually only move or rotate the workpiece in one direction, which limits its application in processing complex jewelry workpieces. For jewelry workpieces with tricky angles, traditional one-way movement or rotation often cannot meet their processing needs.

[0003] In jewelry processing, especially when processing jewelry, it is usually necessary to rotate and move the jewelry workpiece in multiple directions to meet the processing requirements. For example, a ring may have multiple angles and curved surfaces, which need to be precisely processed in different directions to ensure the final product quality and aesthetics. However, traditional laser cutting equipment often cannot provide this multi-dimensional processing capability.

[0004] Therefore, in order to solve the problem that traditional laser cutting equipment cannot process the surfaces with tricky angles required in jewelry processing, a laser jewelry engraving machine that can rotate and move jewelry workpieces in multiple directions is needed. This machine will be able to process jewelry workpieces with complex angles and curved surfaces more accurately, improve processing efficiency and product quality, and meet the market demand for high-quality jewelry.

[0031] The embodiment of the present application provides a laser jewelry engraving machine, comprising:

[0032] A placement table having a placement surface;

[0033] A first rotating mechanism, rotatably connected to the placement table, the first rotating mechanism rotates around a first rotating axis perpendicular to the placement surface;

[0034] A grabbing arm is rotatably connected to the first rotating mechanism, the grabbing arm rotates around a second rotating axis perpendicular to the first rotating axis, and the jewelry workpiece is placed on the grabbing arm.

[0035] A laser transmitter is located on a side of the first rotating mechanism away from the placing table, and the laser transmitter emits laser to engrave the jewelry workpiece on the grabbing arm.

[0036] The laser jewelry engraving machine provided above is designed with a grabbing arm and a first rotating mechanism. By designing the grabbing arm on the first rotating mechanism so that the grabbing arm rotates with the first rotating mechanism, the jewelry workpiece has two different rotation directions during processing, thereby processing more surfaces in the jewelry processing process.

[0037] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] See also Figure 1-Figure 6 The embodiment of the present application provides a laser jewelry engraving machine 100, including a placement table 1, a first rotating mechanism 2, a grabbing arm 3 and a laser emitter 4, wherein the placement table 1 has a placement surface 11, the first rotating mechanism 2 is rotatably connected to the placement table 1, the first rotating mechanism 2 rotates around a first rotation axis a perpendicular to the placement surface 11, the grabbing arm 3 is rotatably connected to the first rotating mechanism 2, the grabbing arm 3 rotates around a second rotation axis b perpendicular to the first rotation axis a, the jewelry workpiece is placed on the grabbing arm 3, the laser emitter 4 is located on a side of the first rotating mechanism 2 away from the placement table 1, and the laser emitter 4 emits laser to engrave the jewelry workpiece on the grabbing arm 3.

[0039] Specifically, the placement table 1 is an object with a placement surface 11, wherein the placement surface 11 is used to place the jewelry workpiece. The placement surface 11 usually represents a horizontal plane. The first rotating mechanism 2 is connected to the placement table 1 and can rotate around a first rotation axis a perpendicular to the placement surface 11. The first rotation axis a usually refers to a virtual rotation axis, indicating that the first rotating mechanism 2 rotates around the first rotation axis a in the design scheme. The purpose of the first rotating mechanism 2 rotating around the first rotation axis a can be achieved in a variety of ways, such as using a motor shaft as a rotation axis for rotation. The function of the first rotation axis a is to enable the jewelry workpiece to rotate on the placement surface 11, providing a rotation direction for the engraving of the jewelry workpiece. The grabbing arm 3 is connected to the first rotating mechanism 2 and can rotate around a second rotation axis b perpendicular to the first rotation axis a. Its function is to provide a fixed support point on the jewelry workpiece so that the workpiece can rotate and move stably for accurate engraving. At the same time, the grab arm 3 rotates around the second rotation axis b to provide a rotation direction for jewelry processing. By making the jewelry workpiece rotate around the first rotation axis a and the second rotation axis b at the same time, the position of the jewelry workpiece facing the laser emitter 4 is changed, so that more surfaces of the jewelry workpiece can be used for laser engraving. The laser emitter 4 is located on the side of the first rotating mechanism 2 away from the placement table 1, and is used to emit laser to engrave the jewelry workpiece on the grab arm 3. Its function is to provide engraving capabilities so that the jewelry workpiece can be finely portrayed and engraved.

[0040] In a specific example, a support frame 5 is further included. The support frame 5 is located on a side of the placement table 1 away from the laser emitter 4 , and the placement table 1 is slidably connected to the support frame 5 .

[0041] Specifically, the support frame 5 mentioned here refers to a structure, which is located on one side of the placement table 1, away from the laser emitter 4. The function of this support frame 5 is to provide additional support and stability to ensure the stability and accuracy of the entire device. The support frame 5 provides additional support on one side of the placement table 1, which helps to increase the stability of the entire device. During the laser engraving process, the jewelry workpiece needs to be placed stably, and the support frame 5 can provide additional support to reduce the shaking or instability of the workpiece. The existence of the support frame 5 can help balance the weight distribution of the entire device. The laser emitter 4 is usually heavy, and placing the support frame 5 on the side away from the laser emitter 4 helps to balance the center of gravity of the entire device, thereby reducing instability. The support frame 5 is usually used as the bottom surface of the laser jewelry engraving machine 100. The support frame 5 is slidably connected to the placement table 1, which means that there is a structure between them that allows the placement table 1 to move within a certain range relative to the support frame 5. This design can make the device more flexible, and the position of the placement table 1 can be adjusted as needed, and the position of the jewelry workpiece can be adjusted to adapt to various processes in jewelry processing.

[0042] In a specific example, the support frame 5 has a first screw transmission mechanism 6 which is transmission-connected to the laser emitter 4 .

[0043] Specifically, the direction in which the first screw transmission mechanism 6 pushes the laser emitter 4 to move is parallel to the placement surface 11. In this way, the position of the laser emitter 4 relative to the jewelry workpiece can be adjusted, which can meet the position change of the laser emitter 4 during laser processing. By controlling the position between the laser emitter 4 and the jewelry workpiece, the laser can engrave the jewelry workpiece at different positions in the transmission direction of the first screw transmission mechanism 6, thereby achieving a more accurate and clearer engraving or cutting effect. Through the push of the first screw transmission mechanism 6, the laser emitter 4 can move in a direction parallel to the placement surface 11, so that it can cover the entire surface of the workpiece. In this way, the workpiece can be fully processed to ensure the consistency and integrity of the processing results. The first screw transmission mechanism 6 can accurately control the moving distance and speed of the laser emitter 4 to meet different processing requirements. This is very important for situations where fine processing or specific processing paths are required on the surface of the workpiece. When using the laser jewelry engraving machine 100, the operator can adjust the position of the laser emitter 4 by controlling the first screw transmission mechanism 6. By rotating the screw on the first screw transmission mechanism 6, the laser emitter 4 can be pushed to move in a direction parallel to the placement surface 11. In this way, the laser transmitter 4 can perform comprehensive processing on the surface of the workpiece to complete the required laser engraving or cutting process.

[0044] In a specific example, a second screw transmission mechanism 7 which is transmission-connected to the placement table 1 is disposed on the support frame 5 , and the second screw transmission mechanism 7 pushes the placement table 1 to move on the support frame 5 .

[0045] Specifically, during the laser engraving or cutting process, it is sometimes necessary to adjust the position of the workpiece in order to achieve a specific processing effect. The second screw transmission mechanism 7 pushes the placement table 1 to move on the support frame 5, and the operator can flexibly adjust the position of the workpiece to align it with the laser emitter 4 or process it at an appropriate position. The second screw transmission mechanism 7 is powered by a motor. This structure is designed mainly to reduce the work intensity of the staff. The placement table 1 is pushed to move on the support frame 5 by the thrust of the screw.

[0046] In a specific example, the first rotating mechanism 2 is provided with a first motor 21 which is transmission-connected to the grabbing arm 3 .

[0047] Specifically, the first motor 21 provides power to the grabbing arm 3, thereby saving the operator's physical strength. At the same time, the first motor 21 drives the grabbing arm 3 to rotate, so as to achieve precise control of the angle of the jewelry workpiece. This is very important for situations where engraving or cutting at different angles is required during laser processing, and can ensure the accuracy and consistency of the processing results.

[0048] In a specific example, a sliding groove 22 is provided on the first rotating mechanism 2 , a positioning rack 23 is slidably connected in the sliding groove 22 , and a rack portion 31 is provided on the grabbing arm 3 , and the rack portion 31 is transmission-connected to the positioning rack 23 .

[0049] Specifically, through the design of the sliding groove 22 and the positioning rack 23, the rotation amplitude of the grabbing arm 3 can be accurately controlled. Because the distance that the positioning rack 23 can move in the sliding groove 22 is limited by the length of the sliding groove 22, the moving distance of the positioning rack 23 is fixed. Before processing, the positioning rack 23 is moved to one end of the sliding groove 22. In this way, when the grabbing arm 3 is driven to rotate by the first motor 21, the positioning rack 23 is driven by the rack part 31 to slide in the positioning groove. When the positioning rack 23 slides from one end of the sliding groove 22 to the other end, the positioning rack 23 will abut against the inner wall of the sliding groove 22, causing the grabbing arm 3 to stop rotating, thereby accurately controlling the rotation amplitude of the grabbing arm 3, thereby controlling the rotation amplitude of the jewelry workpiece to meet different processing requirements.

[0050] In a specific example, a limiting screw 221 is disposed in the sliding groove 22 , and the limiting screw 221 is located on the sliding path of the positioning rack 23 .

[0051] Specifically, the presence of the limit screw 221 can effectively limit the rotation range of the grab arm 3 and ensure that it stops within the designed range. The limit screw 221 extends into the sliding groove 22 to limit the movement of the positioning rack 23. This can prevent the grab arm 3 from excessively rotating beyond the allowed range, thereby protecting the equipment and workpiece from damage or accidents. By setting the position of the limit screw 221, precise control and positioning of the movement of the grab arm 3 can be achieved. This is very important for ensuring that the grab arm 3 stops at the correct position during the processing process, which can ensure the accuracy and consistency of the processing results.

[0052] In a specific example, the grabbing arm 3 is detachably connected to a clamp 32 .

[0053] Specifically, the main function of the clamp 32 is to firmly fix the workpiece on the grab arm 3 to ensure that the workpiece does not move or shake during the processing. This can ensure the stability and accuracy of the processing process. Since the clamp 32 is detachably connected, the clamp 32 can be replaced or adjusted according to actual needs to adapt to workpieces of different shapes, sizes or types. This flexibility enables the laser jewelry engraving machine 100 to handle a variety of different workpiece requirements, and the detachable is usually fixed by using screw connections.

[0054] In a specific example, a weight-reducing groove 24 is provided on the first rotating mechanism 2 .

[0055] Specifically, the main function of the weight reduction groove 24 is to reduce the weight of the rotating component by opening a groove or hole of a certain shape on the rotating component, which helps to reduce the mass of the entire rotating mechanism, reduce the machine load, and thus improve the stability and operating efficiency of the equipment.

[0056] In a specific example, the first rotating mechanism 2 further includes a counterweight 25 , and the counterweight 25 is disposed opposite to the first motor 21 .

[0057] Specifically, the main function of the counterweight 25 is to balance the inertial force in the rotational motion by balancing the masses at different positions of the first rotating mechanism 2. This helps to reduce the load of the motor, protect the operating stability and life of the equipment, and at the same time make the first rotating mechanism 2 more stable during rotation, with less damage to the rotating shaft. When the masses of various parts of the first rotating mechanism 2 are different, the impact on the force-bearing parts will fluctuate during rotation. At the same time, in order to balance the rotation trajectory during rotation, the rotating parts as the axis will bear more force. By setting the counterweight 25, the vibration and vibration generated by the rotating mechanism during movement can be reduced, thereby improving the running stability and processing accuracy of the equipment.

[0058] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
