Description

Technical Field

[0001] The present invention belongs to the technical field of jewelry processing, and particularly relates to a laser engraving device and a laser engraving process for jewelry processing. Background Art

[0002] Jewelry processing is a process of making various precious stones, metals and other raw materials into delicate jewelry ornaments through a series of processes. The jewelry specifications, materials, etc. involved in jewelry processing are all different. Laser engraving (laser carving) in jewelry processing is a process of using a high-energy laser beam to perform fine engraving on the surface or inside of jewelry, which has the characteristics of high precision, high speed, and can achieve complex patterns, and is widely used in the personalized customization and decoration of materials such as metals, precious stones, and pearls. Its principle is to generate a laser beam with a high energy density through a laser device, focus it on the surface or inside of the jewelry, and use the thermal effect, photochemical effect or ionization effect of the laser to locally vaporize, melt or generate microcracks in the material. Jewelry products processed by laser engraving have some popular styles in the market, and because of their good quality and low price, their sales volume is relatively large. Therefore, in the processing of such jewelry, it is necessary to replace relevant processing components due to changes in the model of jewelry raw materials and different laser engraving styles. For example, some spherical jewelry is engraved with Chinese characters or patterns on its outer surface for threading through a rope group to form a string decoration. However, in common jewelry laser processing, it is impossible to complete convenient and fast feeding and fast processing for such unified styles of processing, resulting in the inability to effectively improve the processing efficiency.

[0003] During the research and development of the device, we found an operating process of the device, which can avoid the problem of inability to effectively improve the batch processing efficiency caused by improper operation, and can effectively improve the batch laser engraving efficiency of spherical jewelry. Summary of the Invention

Cavities are formed inside both the front clamping seat and the rear clamping seat and are communicated with an external refrigeration device through two groups of pipelines to form a circulating cooling structure. The front clamping seat is driven by the front clamping telescopic rod and the rear clamping seat is driven by the rear clamping telescopic rod to realize approaching movement, clamp the jewelry, and realize rotation control according to the laser engraving requirements through the front rotating motor and the rear rotating motor.

[0009] As a preferred embodiment, a group of through grooves are vertically penetrated through the rear side surface of the rear bracket. A group of lifting sleeve seats are movably arranged inside the through grooves.

A receiving collecting groove is formed on the upper surface of the receiving seat. A group of guide holes are vertically penetrated through the upper surface of the receiving collecting groove. The receiving collecting groove is an inclined structure that converges towards the guide holes. A collecting conduit is fixedly connected below the guide holes. During processing, the adsorption positioning tube can be connected to an external negative pressure device to generate negative pressure suction on the adsorption positioning seat to adsorb and fix the jewelry to be processed. And when the jewelry to be processed accidentally breaks away from the fixed area during fixation, it can be received by the receiving seat, collected in the receiving collecting groove, and then led out through the guide holes.

The arc-shaped receiving seat is also made of rubber material. When receiving and collecting the jewelry to be processed, there is a free fall of the jewelry to be processed due to the vertical structure during the conveyance through the collecting conduit. It can be received by the arc-shaped receiving seat and then buffered by the damping shock absorber, thereby providing auxiliary protection for the jewelry to be processed.

[0011] As a preferred embodiment, a loading guide seat is further provided in the loading component. The loading guide seat is fixedly connected to the loading ring seat. An arc-shaped transfer loading seat is fixedly connected to the rear side of the loading ring seat. A loading end seat is fixedly connected to the left side of the arc-shaped transfer loading seat.

A buffer adsorption groove is formed at the left end of the upper surface of the loading end seat. A buffer adsorption tube is fixedly connected to the concentric position below the loading end seat. Both the buffer adsorption tube and the loading transfer adsorption tube are respectively connected to an external negative pressure device. The jewelry to be processed is introduced into the loading ring seat through the loading guide seat and arranged in sequence. When the jewelry to be processed passes through the area of the arc-shaped transfer loading seat, negative pressure suction is conveyed through the loading transfer adsorption tube, and the jewelry to be processed is adsorbed by the loading transfer adsorption seat to block and limit a number of sequentially arranged jewelry to be processed. Removing the negative pressure adsorption, the jewelry to be processed can slide down along the loading end seat.

[0012] As a preferred embodiment, two sets of symmetrically arranged lower connecting plates are fixedly connected to the outer ends of both the head and the tail of the feeding ring seat. Two adjusting ring frames arranged front and rear are provided in the adjusting and limiting assembly, and two sets of symmetrically arranged upper connecting plates are fixedly connected to the outer side of the adjusting ring frame; The upper connecting plate and the lower connecting plate are attached to each other and fixedly connected by bolts. Two symmetrically arranged adjusting threaded holes are vertically penetrated through the outer side surface of the adjusting ring frame. An adjusting screw is screwed inside the adjusting threaded hole, and a limiting rod is rotatably connected below the adjusting screw; On the lower side surface of each set of limiting rods, two symmetrically arranged rotating grooves are formed. Inside the rotating grooves, a number of limiting guide rollers for assisting in the feeding and guiding of jewelry are rotatably connected by a number of rotating shafts. According to the specifications of different jewelry to be processed, the adjusting screw is rotated in the adjusting threaded hole to adjust the positions of the two sets of limiting rods, and the rotation of a number of guide rollers is used to assist the movement and positioning of the jewelry to be processed.

[0013] After adopting the above technical solutions, the beneficial effects of the present invention are as follows: By adding a laser engraving machine, a main clamping assembly, a secondary clamping assembly, a feeding assembly and an adjusting and limiting assembly, spherical jewelry is introduced into the feeding ring seat through the feeding guide seat, and then is introduced into the final feeding seat through the arc-shaped intermediate feeding seat during the individual feeding process, and the individual feeding is realized by the adsorption of the feeding intermediate adsorption seat during the transfer; At the end of the final feeding seat, the spherical jewelry is subjected to speed buffering by the negative pressure suction generated by the buffer adsorption groove, and then is clamped and fixed by the front clamping seat and the rear clamping seat in the main clamping assembly and the secondary clamping assembly. Furthermore, the pattern engraving is completed through the laser engraving seat, and according to the pattern specifications, the front rotation motor and the rear rotation motor can be controlled to drive the spherical jewelry to realize rotational engraving; In addition, for some other styles of jewelry, they can also be fixedly adsorbed by negative pressure through the adsorption positioning seat, providing multiple fixing options before laser engraving, and after completion, they are clamped by electric clamping and then controlled to be discharged by rotation through the rotating seat, thereby improving the batch laser engraving efficiency.

[0014] The present invention also relates to a laser engraving process for jewelry processing described above, including the following steps: a. During the laser engraving of spherical jewelry to be processed, the feeding assembly is used to automatically feed the jewelry to be processed, and the front clamping telescopic rod drives the front clamping seat and the rear clamping telescopic rod drives the rear clamping seat to move closer, so as to clamp the jewelry. In addition, according to the laser engraving requirements, the front rotation motor and the rear rotation motor respectively drive the front clamping seat and the rear clamping seat to realize rotation control, so as to drive the jewelry to be processed to rotate circumferentially and improve the adaptation range of the laser engraving pattern; Secondly, during processing, the adsorption positioning seat can also generate negative pressure suction through the connection between the adsorption positioning tube and an external negative pressure device to adsorb and fix the jewelry to be processed. And during the fixation of the jewelry to be processed, if it accidentally breaks away from the fixation area, it can be received by the receiving seat, collected in the receiving collecting groove, and then exported through the guide hole. Among the jewelry to be processed received, collected, and collected, there is a vertical structure during the guiding through the collecting conduit, which causes the free fall of the jewelry to be processed. It can be received by the arc-shaped receiving seat and then buffered by the damping shock absorber, thereby providing auxiliary protection for the jewelry to be processed; Moreover, based on the above processing implementation, after the laser engraving is completed, the electric gripper clamps the jewelry after laser engraving, and the position is transferred under the rotation of the rotating seat. It can control the action position of the electric gripper through the feeding telescopic rod one and the feeding telescopic rod two, realizing the automatic feeding operation of the processed jewelry, thereby improving the batch laser engraving efficiency.

[0015] b. Before batch laser engraving of spherical jewelry, the prepared jewelry to be processed is introduced into the loading ring seat through the loading guide seat and arranged in sequence. When the jewelry to be processed passes through the arc-shaped transfer loading seat area, negative pressure suction is guided through the loading transfer adsorption tube, and the jewelry to be processed is adsorbed by the loading transfer adsorption seat, blocking and limiting a number of sequentially arranged jewelry to be processed. After removing the negative pressure adsorption, the jewelry to be processed can slide down along the loading end seat. The loading ring seat, the arc-shaped transfer loading seat, and the loading end seat are all arranged with a height difference at the head and tail, and can achieve natural sliding without external force; Secondly, when the jewelry to be processed slides to the end of the loading end seat, the buffer adsorption tube guides negative pressure suction to adsorb the jewelry to be processed at the position of the buffer adsorption groove, slowing down the sliding speed of the jewelry to be processed and assisting its guiding to the processing position.

[0016] c. During the laser engraving processing of jewelry, there are various specifications of jewelry to be processed. According to different specifications of the jewelry to be processed, the adjusting stud rotates in the adjusting threaded hole, driving the limiting rod to approach or move away from the center of the loading ring seat, so that the jewelry to be processed is restricted between the loading ring seat and two symmetrically distributed limiting rods during guiding. In addition, several groups of guiding rollers are rotatably connected to the inner side of the lower end of the limiting rod, so that the guiding rollers are in direct contact with the jewelry to be processed, forming rolling friction for the movement of the jewelry to be processed, thereby being able to assist the loading operation of the jewelry to be processed.

[0017] After adopting the above process, the beneficial effect of the present invention is that the spherical jewelry to be processed in batches is introduced into the processing position one by one through the loading assembly, and the main clamping assembly and the auxiliary clamping assembly cooperate to complete the adsorption or clamping and fixation of the jewelry, improving the automation degree of batch processing and being able to improve the laser engraving efficiency.

[0041] The present invention also relates to a laser engraving process for jewelry processing, comprising the following steps: In the laser engraving of spherical jewelry to be processed, the feeding assembly 200 automatically feeds the jewelry to be processed, and the front clamping telescopic rod 304 drives the front clamping seat 305 and the rear clamping telescopic rod 213 drives the rear clamping seat 215 to move closer, so as to clamp the jewelry. In addition, according to the laser engraving requirements, the front rotation motor 303 and the rear rotation motor 214 respectively drive the front clamping seat 305 and the rear clamping seat 215 to achieve rotation control, so as to drive the jewelry to be processed to rotate circumferentially and improve the adaptability range of laser engraving patterns; Secondly, during the processing, the connection between the adsorption positioning tube 207 and an external negative pressure device can also be used to make the adsorption positioning seat 208 generate negative pressure suction to adsorb and fix the jewelry to be processed. When the jewelry to be processed accidentally breaks away from the fixed area during the fixation, it can be received by the receiving seat 209, and after being collected in the receiving collecting groove 210, it is led out through the guide hole 211. Among the jewelry to be processed received, collected and collected, there is a free fall of the jewelry to be processed due to the vertical structure during the guiding through the collecting conduit 212, which can be received by the arc-shaped receiving seat 218 and then buffered by the damping shock absorber 217, so as to provide auxiliary protection for the jewelry to be processed; And based on the above processing implementation, after the laser engraving is completed, the electric claw 108 clamps the jewelry after laser engraving, and the position transfer is completed under the rotation of the rotating seat. The action position of the electric claw 108 can be controlled by the blanking telescopic rod one 106 and the blanking telescopic rod two 107, so as to realize the automatic blanking operation of the processed jewelry, and improve the batch laser engraving efficiency; In addition, before the batch laser engraving of spherical jewelry, the prepared jewelry to be processed is introduced into the feeding ring seat 402 through the feeding guide seat 401 and arranged in sequence. When the jewelry to be processed passes through the arc-shaped transfer feeding seat 404 area, the negative pressure suction is guided through the feeding transfer adsorption tube 410, and the feeding transfer adsorption seat 409 adsorbs the jewelry to be processed, so as to block and limit a plurality of jewelry to be processed arranged in sequence. After removing the negative pressure adsorption, the jewelry to be processed can slide down along the feeding end seat 405. The feeding ring seat 402, the arc-shaped transfer feeding seat 404 and the feeding end seat 405 are all arranged with a height difference structure at the head and tail, and can realize natural sliding without external force; Secondly, when the jewelry to be processed slides to the end of the feeding end seat 405, the buffer adsorption tube 407 guides the negative pressure suction to make the buffer adsorption groove 406 adsorb the jewelry to be processed by negative pressure, slow down the sliding speed of the jewelry to be processed, and assist its guiding to the position to be processed; In the process of laser engraving processing of jewelry, there are various specifications of jewelry to be processed. According to different specifications of the jewelry to be processed, the adjusting stud 503 is rotated in the adjusting threaded hole, driving the limiting rod 504 to approach or move away from the center of the loading ring seat 402, so that the jewelry to be processed is restricted between the loading ring seat 402 and two groups of symmetrically distributed limiting rods 504 during feeding. In addition, several groups of feeding rollers 506 are rotatably connected to the inner sides of the lower ends of the limiting rods 504 through rotating shafts, so that the feeding rollers 506 are in direct contact with the jewelry to be processed, forming rolling friction for the movement of the jewelry to be processed, thereby being able to assist in the feeding operation of the jewelry to be processed.
