This patent can quickly feed and process block gold jewelry that needs laser processing through the provided feeding plate, groove, feeding barrel and first electric push rod, and after the processing is completed, the jewelry inside the groove can be quickly pushed out by the pushing mechanism, saving the process of manual feeding and material retrieval, reducing labor costs, and also improving processing efficiency. However, in the above patent, after the processing is completed, the jewelry inside the groove can be quickly pushed out by the pushing mechanism, which saves the process of manual feeding and removing materials, reduces labor costs, and also improves processing efficiency. However, when laser processing gold, the position of the gold needs to be fixed, so the four directions of the gold are fixed. As a result, when the laser processing is performed on the edge of the gold, the fixing device will block the edge of the gold, thereby affecting the effect of the gold processing.

[0003] The Chinese patent CN118287820B discloses a kind of light beam shaping device for gold jewelry laser processing, including device ontology, the front of the device ontology is rotatably installed with door plate, the inside of the device ontology is provided with moving device, the moving end of the moving device is fixedly installed with lifting device, the output end of the lifting device is fixedly installed with processing device, the inner wall bottom of the device ontology is fixedly installed with elastic telescopic block, the top of the elastic telescopic block is fixedly installed with workbench, positioning device is arranged on the workbench;Among them, the positioning device includes clamping plate, sliding block, convex block, L-shaped plate, arc block, moving plate and trapezoidal block, the inside of the workbench is provided with sliding slot, the clamping plate is slidably installed in the inside of sliding slot, the sliding block is slidably installed on the top of clamping plate, the convex block is fixedly installed on the bottom of sliding block, the L-shaped plate is slidably installed on the side of clamping plate close to convex block, the arc block is fixedly installed on the top of L-shaped plate, the moving plate is slidably installed at the bottom of sliding slot, the trapezoidal block is fixedly installed on the top of moving plate, the surface of the processing device is fixedly installed with bifurcation block, a spring is arranged between the clamping plate and sliding slot, a spring is arranged between the sliding block and clamping plate, a spring is arranged between the moving plate and sliding slot, bifurcation block will push sliding block to move, sliding block will drive convex block to move when moving, convex block will push arc block and L-shaped plate to move downward when moving, L-shaped plate will push moving plate to move downward when moving downward.

[0004] Although the above scheme can avoid the blocking of the clamping position to the processing of gold, the clamping mechanism and the switching mode of the clamping mechanism using the above scheme cannot adapt to the processing of various ornaments. The clamping mechanism in the above scheme is more suitable for clamping block-shaped gold, and cannot clamp ring-shaped structures such as bracelets and rings. In existing gold processing, patterns are often engraved on the outer surface of gold by laser. Therefore, when engraving by laser, the bracelet or ring needs to be in a rotating state. The existing technical device cannot meet the above processing requirements. SUMMARY

[0005] In response to the above problems, a laser processing device and a processing method for gold jewelry processing are provided. When in use, the annular jewelry is placed in a clamping unit. After the clamping unit clamps the annular jewelry, the laser head can process the annular jewelry. It is worth noting that when the laser head processes the annular jewelry, it mainly processes the outer circumferential wall of the annular jewelry. In the traditional processing method, the outer circumferential wall of the annular jewelry needs to be manually rotated when engraving, which is cumbersome to operate and cannot ensure the uniformity of the rotation speed during rotation. After using this device, the above situation can be avoided. The working principle of this device is as follows: the annular jewelry is placed on the supporting wheel so that the lower side of the annular jewelry can be supported by two supporting wheels respectively. The pressing wheel extends into the inner ring of the annular ornament along its axis. Once fully inserted, it descends vertically and presses the inner wall of the annular ornament. Two clamping plates are arranged horizontally along the axis of the support wheel. The two clamping plates can move toward or away from each other. The annular ornament placed on the support wheel is positioned between the two clamping plates. When the pressing wheel contacts the inner wall of the annular ornament, the two clamping plates simultaneously move toward the annular ornament. When both clamping plates contact both ends of the annular ornament, they stop moving. The pressing wheel and the support wheel rotate synchronously, causing the annular ornament to rotate at a constant speed. Simultaneously, the laser head is activated and engraves a pattern on the outer circumference of the annular ornament. This ensures that the annular ornament is both stably clamped and rotates at a constant speed during laser engraving, thus ensuring the quality of the engraved pattern.

[0006] In order to solve the problems of the existing technology, the present invention provides a laser processing equipment, including a laser head; including a clamping unit for clamping the annular ornament, the clamping unit includes two horizontally arranged support wheels, the support wheels are used to support the lower part of the annular ornament, and the pressing wheel is arranged above the support wheel parallel to the axis of the support wheel. The pressing wheel passes through the inner ring of the annular ornament and presses the inner ring wall of the annular ornament. When the laser head is running, the support wheel and the pressing wheel simultaneously drive the annular ornament to rotate.

[0007] Preferably, two clamping plates are arranged horizontally along the axial direction of the support wheel, and the annular ornament placed on the support wheel is located between the two clamping plates. When the annular ornament is placed between the two clamping plates, the two clamping plates approach each other, and after the two clamping plates respectively clamp the two ends of the annular ornament, the clamping plates stop moving.

When the first pressure sensor and the second pressure sensor detect pressure at the same time, the two clamping plates approach each other. A third pressure sensor is provided at the ends where the two clamping plates are close to each other. After the third pressure sensor detects the pressure, the clamping plates stop moving.

[0010] Preferably, a telescopic unit is provided at the end of the pressing wheel to drive the pressing wheel to move along the moving direction of the clamping plate. A groove is provided on the side wall of the pressing wheel along the axis of the pressing wheel. The pressing wheel is key-connected to the telescopic unit through the groove and slides along the moving direction of the clamping movement.

[0011] Preferably, a side plate is provided at the end of the supporting wheel, and a third driving unit for driving the pressing wheel and the supporting wheel to rotate synchronously is provided on the side plate. When the pressing wheel and the supporting wheel rotate, the rotation direction of the pressing wheel toward the side of the annular ornament is the same as the rotation direction of the supporting wheel toward the side of the annular ornament.

The annular ornament placed on the support wheel is located between the two clamping plates. When the pressing wheel contacts the inner wall of the annular ornament, the two clamping plates simultaneously move toward the annular ornament. When both clamping plates contact both ends of the annular ornament, they stop moving. The pressing wheel and the support wheel rotate synchronously, causing the annular ornament to rotate at a constant speed. Simultaneously, the laser head is activated and engraves the pattern on the outer circumference of the annular ornament. This ensures that the annular ornament is both stably clamped and rotates at a constant speed during laser engraving, thus ensuring the quality of the engraved pattern.

[0034] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Reference Figures 1-4 and Figure 10A laser processing device comprises a laser head 1; a clamping unit 2 for clamping a ring-shaped ornament 3, the clamping unit 2 comprising two horizontally arranged supporting wheels 21 for supporting the lower part of the ring-shaped ornament 3, and a pressing wheel 22 arranged above the supporting wheels 21 along the axis of the supporting wheels 21, the pressing wheel 22 penetrating the inner ring of the ring-shaped ornament 3 and pressing the inner ring wall of the ring-shaped ornament 3, the supporting wheels 21 and the pressing wheel 22 driving the ring-shaped ornament 3 to rotate simultaneously when the laser head 1 operates.

[0036] A first driving unit 211 is provided between the two supporting wheels 21 for driving the two supporting wheels 21 to move closer to or away from each other, and a side plate 27 is provided at the end of the supporting wheel 21. The side plate 27 is provided with a first sliding groove 271 for the supporting wheel 21 to slide in the horizontal direction. There are two first sliding grooves 271, and the two first sliding grooves 271 are respectively used for the two supporting wheels 21 to move. The first driving unit 211 includes a first threaded rod 2111, a first rotation driver 2112 and an extension plate 2113. The extension plate 2113 is provided at the end of the supporting wheel 21. The extension plate 2113 passes through the first sliding groove 271 and slides with the first sliding groove 271 along the extension direction of the first sliding groove 271. The first threaded rod 2111 is provided along the extension direction of the first sliding groove 271. The two extension plates 2113 are respectively passed through and threadedly engaged with the two extension plates 2113. The threads on the first threaded rod 2111 are evenly divided into two sections, and the spiral directions of the two sections are opposite. The first rotation driver 2112 is set at the end of the first threaded rod 2111. The first rotation driver 2112 can drive the first threaded rod 2111 to rotate. In this way, when the first rotation driver 2112 is started, the first threaded rod 2111 can drive the two extension plates 2113 to move closer to or away from each other. The first rotation driver 2112 is preferably a servo motor, so that the two support wheels 21 can be properly adjusted according to the size of the annular ornament 3 to be processed. That is, when the diameter of the annular ornament 3 is too large and the distance between the two support wheels 21 is too small, it is easy for the two to move closer or further away from each other. In the case that the two support wheels 21 cannot stably support the annular ornament 3, a first driving unit 211 is provided so that the two support wheels 21 can be adjusted according to the annular ornaments 3 of different sizes, thereby meeting the processing requirements. When in use, the annular ornament 3 is placed in the clamping unit 2. After the clamping unit 2 clamps the annular ornament 3, the laser head 1 can process the annular ornament 3. It is worth noting that when the laser head 1 processes the annular ornament 3, it mainly processes the outer circumferential wall of the annular ornament 3. In the traditional processing method, the outer circumferential wall of the annular ornament 3 needs to be manually rotated when engraving, which is cumbersome to operate and cannot ensure the uniformity of the rotation speed during rotation. After using this device, the above situation can be avoided. Regarding the working principle of this device The process is as follows: the annular ornament 3 is placed on the supporting wheel 21 so that the lower side of the annular ornament 3 can be supported by the two supporting wheels 21 respectively, and the pressing wheel 22 extends into the inner ring of the annular ornament 3 along the axial direction of the annular ornament 3. When the pressing wheel 22 is fully extended into the inner ring of the annular ornament 3, the pressing wheel 22 descends in the vertical direction and presses the inner ring wall of the annular ornament 3. Two clamping plates 23 are arranged horizontally in the axial direction of the supporting wheel 21. The two clamping plates 23 can approach or move away from each other. The annular ornament 3 placed on the supporting wheel 21 is located between the two clamping plates 23. When the pressing wheel 22 contacts the inner ring wall of the annular ornament 3, the two clamping plates 23 simultaneously approach the annular ornament 3. When the two clamping plates 23 simultaneously contact the two ends of the annular ornament 3,The two clamping plates 23 stop moving, while the pressing wheel 22 and the supporting wheel 21 rotate synchronously, causing the ring-shaped ornament 3 to rotate at a constant speed. At the same time, the laser head 1 starts to engrave the pattern on the outer circumference of the ring-shaped ornament 3. This ensures that the ring-shaped ornament 3 is both stably clamped and rotates at a constant speed during laser engraving, thus ensuring the quality of the engraved pattern.

[0037] Reference Figure 6 and Figure 7 : Two clamping plates 23 are arranged horizontally along the axial direction of the support wheel 21. The annular ornament 3 placed on the support wheel 21 is located between the two clamping plates 23. When the annular ornament 3 is placed between the two clamping plates 23, the two clamping plates 23 approach each other, and after the two clamping plates 23 clamp the two ends of the annular ornament 3 respectively, the clamping plates 23 stop moving.

[0038] Reference Figure 6 、 Figure 9 and Figure 10 : A second driving unit 24 is provided on the two clamping plates 23 to drive the two clamping plates 23 to move closer to or away from each other. A second threaded rod 241 is provided in the second driving unit 24. The second threaded rod 241 passes through the two clamping plates 23 along the moving direction of the clamping plates 23, and the clamping plates 23 are threadedly matched with the second threaded rod 241. The threads on the second threaded rod 241 are evenly divided into two sections. The two clamping plates 23 are respectively arranged on the two sections of threads, and the spiral directions of the two sections of threads are opposite.

[0039] The second driving unit 24 also includes a guide rod 242 and a second rotation driver 243. The guide rod 242 is arranged on one side of the second threaded rod 241 in parallel with the axial direction of the second threaded rod 241. The guide rod 242 passes through the two clamping plates 23 in sequence along the moving direction of the clamping plates 23. The second rotation driver 243 is arranged at the end of the second threaded rod 241. The second rotation driver 243 is used to drive the second threaded rod 241 to rotate. Since the two clamping plates 23 are respectively arranged on the two sections of the second threaded rod 241, and the spiral directions of the threads on the two sections of the second threaded rod 241 are opposite, after the second threaded rod 241 rotates, the second threaded rod 2 41 can make the two clamping rods move closer to or farther away from each other. The second rotary driver 243 is preferably a servo motor. When the second rotary driver 243 is started, the second rotary driver 243 drives the second threaded rod 241 to rotate, so that the two clamping plates 23 can move closer to each other and clamp the annular ornament 3. It is worth noting that in addition to being used to place the annular ornament 3, the support wheel 21 can also support ordinary square ornaments. That is, after placing an ordinary square ornament on the support wheel 21, the clamping plates 23 move closer to each other, and the clamping plates 23 can clamp the two ends of the square ornament, so that the processing equipment can adapt to the processing of ornaments of various shapes. The thread on the second threaded rod 241 is arranged into two sections, and the spiral directions of the two sections of the thread are opposite, which can also ensure that the two clamping plates 23 can keep synchronized when moving. After the two clamping plates 23 clamp the annular ornament 3, the positioning of the annular ornament 3 clamped by the two clamping plates 23 can be more accurate, avoiding the pattern deviation when the laser head 1 is engraving the outer ring wall of the annular ornament 3.

[0040] Reference Figures 1-11 : A first pressure sensor is provided on the periphery of the supporting wheel 21, and a second pressure sensor is provided on the periphery of the pressing wheel 22. When the first pressure sensor and the second pressure sensor detect pressure at the same time, the two clamping plates 23 approach each other. A third pressure sensor is provided at the ends where the two clamping plates 23 are close to each other. After the third pressure sensor detects the pressure, the clamping plates 23 stop moving.

[0041] When the annular ornament 3 is placed on the two supporting wheels 21, the first pressure sensor provided on the supporting wheel 21 can monitor the pressure generated by the annular ornament 3, and then the pressing wheel 22 extends into the ring of the annular ornament 3. When the pressing wheel 22 is fully extended into the ring of the annular ornament 3, the pressing wheel 22 descends in the vertical direction, and the pressing wheel 22 presses the inner ring wall of the annular ornament 3. At this time, the first pressure sensor and the second pressure sensor both monitor the pressure, and the two clamping plates 23 approach each other under the drive of the second driving unit 24 and finally clamp the annular ornament 3. When the third pressure sensors on the two clamping plates 23 both monitor the pressure value, the two clamping plates 23 stop rotating, thus completing the clamping.

[0042] With reference to Figure 7 and Figure 11 : the end of the pressing wheel 22 is provided with a telescopic unit 25 for driving the pressing wheel 22 to move along the moving direction of the clamping plate 23, the side wall of the pressing wheel 22 is provided with a groove 221 along the axis of the pressing wheel 22, the pressing wheel 22 is keyed connected with the telescopic unit 25 through the groove 221 and is slidingly fitted along the moving direction of the clamping moving.

[0043] The telescopic unit 25 includes a telescopic sleeve 251, the telescopic sleeve 251 is arranged at the end of the pressing wheel 22 along the axis of the pressing wheel 22, the pressing wheel 22 is slidingly fitted with the telescopic sleeve 251 along the extension direction of the telescopic sleeve 251, the telescopic sleeve 251 contains hydraulic oil, and the telescopic sleeve 251 makes the pressing wheel 22 located in the telescopic sleeve 251 to extend or retract through the injection and extraction of the hydraulic oil.

[0044] With reference to Figure 8 and Figure 9 : the end of the supporting wheel 21 is provided with a side plate 27, the third driving unit 26 for driving the pressing wheel 22 and the supporting wheel 21 to rotate synchronously is arranged on the side plate 27, when the pressing wheel 22 and the supporting wheel 21 rotate, the rotating direction of the pressing wheel 22 towards the side of the annular ornament 3 is the same as the rotating direction of the supporting wheel 21 towards the side of the annular ornament 3.

[0045] With reference to Figure 8 and Figure 9 : the telescopic unit 25 includes a telescopic sleeve 251 sleeved on the periphery of the pressing wheel 22 along the axis of the pressing wheel 22, the third driving unit 26 includes a first driving wheel 261 arranged at one end of the pressing wheel 22, the telescopic sleeve 251 penetrates through the first driving wheel 261 along the axis of the first driving wheel 261, and the telescopic sleeve 251 is a non-circular structure at the penetration position of the first driving wheel 261, when the first driving wheel 261 rotates, the telescopic sleeve 251 rotates synchronously with the first driving wheel 261.

[0046] A second sliding groove 272 is vertically opened on the side plate 27, and the pressing wheel 22 slides and cooperates with the second sliding groove 272 along the extension direction of the second sliding groove 272. The third driving unit 26 also includes a second driving wheel 262, a third driving wheel 263, a fourth driving wheel 264, a driving belt 265, an electric push rod 266, a spring 267 and a third rotation driver 268. The second driving wheel 262 is set at one end of the supporting wheel 21, and the second driving wheel 262 rotates synchronously with the supporting wheel 21. The third driving wheel 263 is positioned and rotated on the side plate 27, the third driving wheel 263 is located on one side of the second driving wheel 262, and the so-called positioning rotation means that the spatial position of the third driving wheel 263 does not change when it rotates. The fourth driving wheel 264 is arranged above the third driving wheel 263 in the vertical direction, and the fourth driving wheel 264 can move in the vertical direction. The driving belt 265 is wound around the first driving wheel 261, the second driving wheel 262, the third driving wheel 263 and the fourth driving wheel 264 in sequence, and the driving belt 265 is respectively wound around the first driving wheel 261, the second driving wheel 262, the third driving wheel 263 and the fourth driving wheel 264. The driving wheel 262, the third driving wheel 263 and the fourth driving wheel 264 are in transmission cooperation. The third rotation driver 268 is provided at the end of one of the third driving wheels 263. The third rotation driver 268 is preferably a servo motor. The spring 267 is vertically provided on the upper part of the first driving wheel 261. The electric push rod 266 is vertically provided on the upper part of the fourth driving wheel 264. The electric push rod 266 can drive the fourth driving wheel 264 to move in the vertical direction. When the electric push rod 266 drives the fourth driving wheel 264 to rise in the vertical direction, the first driving wheel 261 is rotated by the third rotation driver 268. The moving wheel 261 descends along the extension direction of the second slide groove 272, and the spring 267 located on the upper part of the first driving wheel 261 is gradually stretched. The function of the spring 267 is to enable the first driving wheel 261 to stably transmit with the driving belt 265, and at the same time, it can also enable the driving belt 265 to stably transmit with the second driving wheel 262, the third driving wheel 263 and the fourth driving wheel 264, thereby avoiding slipping of the driving belt 265 during transmission, thereby ensuring that the supporting wheel 21 and the pressing wheel 22 can drive the annular ornament 3 to rotate at a uniform speed.

[0047] Reference Figure 1 and Figure 2 : A slide 4 is provided at the bottom of the clamping unit 2 for driving the clamping unit 2 to move horizontally below the laser head 1.

[0048] By setting up the slide 4, it is more convenient for the staff to install or remove the annular ornament 3. That is, when installing or removing the annular ornament 3, the slide 4 drives the clamping unit 2 to one end of the slide 4. When the annular ornament 3 needs to be installed, the slide 4 drives the clamping unit 2 to move to the bottom of the laser head 1. At this time, the clamping unit 2 can drive the annular ornament 3 to the bottom of the laser head 1, avoiding the staff from installing or unloading directly under the laser head 1, thereby improving safety.

[0049] Reference Figure 1 and Figure 2 : A support platform 5 is provided at the lower part of the slide 4 to support the slide 4. The table surface of the support platform 5 is an inclined structure, and a blanking chute 51 is provided around the support platform 5.

[0050] Gold debris dropped after the laser head 1 engraves the ring-shaped ornament 3 is guided into the stopping trough 51 through the inclined structure on the support platform 5 .

[0051] Reference Figures 1-11 The present invention also relates to a method for processing gold jewelry using a laser processing device, which uses a laser processing device and has the following specific steps:

[0052] S1. Place the annular ornament 3 on the supporting wheels 21 so that the lower side of the annular ornament 3 can be supported by the two supporting wheels 21 respectively.

[0053] S2. The pressing wheel 22 extends into the inner ring of the annular ornament 3 along the axial direction of the annular ornament 3. When the pressing wheel 22 is completely extended into the inner ring of the annular ornament 3, the pressing wheel 22 descends in the vertical direction and presses the inner ring wall of the annular ornament 3.

[0054] S3. The two clamping plates 23 approach the annular ornament 3 at the same time. When the two clamping plates 23 contact the two ends of the annular ornament 3 at the same time, the two clamping plates 23 stop moving, and the pressing wheel 22 and the supporting wheel 21 rotate synchronously, so that the annular ornament 3 rotates at a uniform speed. At the same time, the laser head 1 is started, and the laser head 1 engraves the pattern on the outer circumferential wall of the annular ornament 3.

[0055] The above embodiments merely represent one or more embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the appended claims.
