Description

[0002] There are many types of alloy jewelry, including but not limited to necklaces, bracelets and rings. Rings generally include two types: ring rings and inlaid rings. Ring rings are complete alloy rings with decorative diamonds welded on the outer surface (such as Figure 1 ), while the inlaid ring consists of an alloy ring with a notch (such as Figure 2 ) and decorations such as gems or pearls welded in the gap of the alloy ring.

[0003] At present, the processing method commonly used for processing the above two types of rings is to manually hold the ring and weld the broken diamonds to the surface of the complete alloy ring through a laser welding machine, or to weld a bracket loaded with gems or pearls to the notch of the notched alloy ring.

[0004] There are some problems when processing rings in the above manner: when processing annular rings with a laser welding machine, it is difficult for the operator to ensure that the angle of each adjustment is the same when adjusting the position of the complete alloy ring, and when processing inlaid rings with a laser welding machine, in order to ensure the welding effect, the notch on the notched alloy ring needs to be kept facing upward at all times, so that the laser welding machine can weld the bracket loaded with gems or pearls to the notch of the notched alloy ring, and manual adjustment may result in deviations; at the same time, during the above operations, the operator's hands cannot avoid shaking, both of which will reduce the processing accuracy and result in the processed pattern being not beautiful; in addition, the above processing methods can often only process one ring at a time, which makes the processing efficiency need to be improved.

DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

[0033] See also Figure 3-Figure 5 , an automatic laser welding device for alloy jewelry, including a laser welding machine, an L-shaped plate 1 is fixedly connected to the bottom of the operating space of the laser welding machine, the top of the vertical section of the L-shaped plate 1 is rotatably connected to a mounting tube 2 extending from left to right, a flat groove parallel to the horizontal section of the L-shaped plate 1 is opened from right to left at the upper position of the side wall of the mounting tube 2, an inverted T-shaped weight block 21 is fixedly connected to the lower position of the left end side wall of the mounting tube 2 to ensure that the mounting tube 2 can be rotated and reset after each operation is completed, a plurality of annular grooves 22 are evenly arranged on the left and right sides of the side wall of the mounting tube 2, and a positioning mechanism 3 for positioning the ring position is arranged on the outer wall of the mounting tube 2 and on the left and right sides of each annular groove 22.

[0034] See also Figure 4-Figure 6 The left and right ends of the mounting tube 2 are fixedly connected with sealing plates 23, and the two sealing plates 23 are slidably connected with a center rod 4. The outer wall of the center rod 4 and the positions on the left and right sides of the right sealing plate 23 are fixedly sleeved with limit rings 41. The center rod 4 and the mounting tube 2 are also commonly connected with an adjustment mechanism 5 for adjusting the position of the ring. A plurality of clamping mechanisms 6 that cooperate with the annular groove 22 and are used to fix the ring are evenly connected to the center rod 4 from left to right.

[0035] See also Figure 4 and Figure 5 The clamping mechanism 6 includes a spindle-shaped seat 61, which is fixedly sleeved on the center rod 4, and the positions of the spindle-shaped seat 61 and the annular groove 22 correspond to each other. Three round rods 62 extending in the radial direction of the annular groove 22 are evenly slidably penetrated on the annular groove 22 in the circumferential direction. The end of the round rod 62 close to the spindle-shaped seat 61 is fixedly connected with a wedge block 63 matching the spindle-shaped seat 61, and the end of the round rod 62 away from the spindle-shaped seat 61 is fixedly connected with a rubber block 64. The left end of the center rod 4 is connected to a cooling mechanism 7 for cooling the ring, and the left end of the mounting tube 2 is connected to a driving mechanism 8 for driving the mounting tube 2 to rotate.

[0036] See also Figure 5 The positioning mechanism 3 includes an arc-shaped limit strip 31, and the arc-shaped limit strip 31 is grouped into two symmetrical ones. Two groups of arc-shaped limit strips 31 are fixedly arranged symmetrically on the left and right sides of the annular groove 22 on the side wall of the mounting tube 2, and the arc-shaped limit strip 31 is made of elastic deformable material.

[0037] During specific operation, in the initial state, the right-side limit ring 41 fits with the right end face of the right sealing plate 23, and the spindle-shaped seat 61 is located on the right side of the wedge block 63. When processing the annular ring, first, multiple alloy rings are successively mounted on each annular groove 22, and ensure that the annular ring is located between the two symmetrical arc-shaped limit strips 31, and then the center rod 4 is pulled to the right to make the left-side limit ring 41 fit with the right sealing plate 23.

[0038] During this process, the spindle-shaped seat 61 will move to the right synchronously with the center rod 4, thereby driving the three round rods 62 to move synchronously outward along the radial direction of the mounting tube 2 through the three wedge blocks 63, and then supporting the alloy ring from the inside to the outside through the three rubber blocks 64, and then starting the driving mechanism 8 and the cooling mechanism 7. When the annular ring is processed, the driving mechanism 8 drives multiple complete alloy rings to rotate synchronously and intermittently. During the intervals when the complete alloy rings are stationary, the staff will stick the broken diamonds to the upper side walls of each complete alloy ring, and then use a laser welding machine to weld the broken diamonds to the surface of the alloy ring.

[0039] When processing the inlaid ring, first, multiple notched alloy rings are sequentially mounted on each annular groove 22. While ensuring that the notched alloy ring is located between the two symmetrical arc-shaped limit strips 31, it is also necessary to ensure that the notch of the notched alloy ring is facing upward. Then, the position of the notched alloy ring is fine-tuned by the adjustment mechanism 5 so that the notch is facing directly upward. The center rod 4 is then pulled to the right so that the left limit ring 41 fits with the right sealing plate 23. The notched alloy ring is fixed and clamped from the inside to the outside by the rubber block 64 in the same fixing manner.

[0040] Then, the bracket loaded with gems or pearls to be welded is manually installed on the notch of the notch alloy ring, and the two are welded by a laser welding machine. When the welding is completed, the cooling mechanism 7 emits cold air from the inside to the outside through the mounting tube 2 to quickly cool down the welding point during the welding process.

[0041] See also Figure 6 The adjustment mechanism 5 includes a mounting assembly 51, and the mounting assembly 51 is connected to the flat groove of the mounting tube 2. A slide groove 52 extending in the left-right direction is opened from top to bottom on the side wall of the center rod 4 near the right end. A folding rod 53 is connected to the slide groove 52 and the mounting assembly 51. The front and rear side walls of the folding rod 53 are in contact with the slide groove 52, and a positioning assembly 54 is connected to the folding rod 53.

[0042] See also Figure 6 and Figure 7The mounting assembly 51 includes a limit seat 511, which is fixedly connected to the top of the mounting tube 2, and the limit seat 511 is located on the left side of the leftmost annular groove 22, and a waist-shaped groove 512 is provided on the limit seat 511 to penetrate left and right, and a rectangular sleeve 513 is slidably connected to the outside of the limit seat 511 up and down, and the left end of the upper horizontal section of the folding rod 53 is slidably penetrated and connected to the rectangular sleeve 513, and the upper horizontal section of the folding rod 53 and the rectangular sleeve 513 are jointly connected with a reset module 514; the reset module 514 includes a rod sleeve 5141, and a rod sleeve 5141 is fixedly provided on the left side of the upper horizontal section of the folding rod 53, and the rod sleeve 5141 is located on the right side of the rectangular sleeve 513, and the rod sleeve 5141 and the rectangular sleeve 513 are connected by a reset spring 5142.

[0043] See also Figure 6 and Figure 8 The positioning assembly 54 includes a trapezoidal paddle 541, and a plurality of trapezoidal paddles 541 corresponding to the annular groove 22 and opening to the left are evenly fixedly connected on the horizontal section above the folding rod 53. The distance between the two transverse sections of the trapezoidal paddle 541 increases from left to right. The bottom of the slide 52 is connected to a rising module 542 that matches the folding rod 53; the rising module 542 includes a trapezoidal block 5421, and the bending part of the folding rod 53 is arc-shaped. A trapezoidal block 5421 with an inclined surface facing right and matching the bending part of the folding rod 53 is fixedly connected at the center position of the bottom of the slide 52, and a push block 5422 is fixedly connected to the right end of the folding rod 53.

[0044] During specific operation, after multiple notched alloy rings are sequentially sleeved on each annular groove 22 so that the notched alloy ring is located between the two symmetrical arc-shaped limit strips 31 with the notch facing upward, the push block 5422 is pushed to the left and then the folding rod 53 is pressed to the left. During this process, due to the limitation of the trapezoidal block 5421, the horizontal section below the folding rod 53 will rise along the inclined surface of the trapezoidal block 5421 to the horizontal plane above the trapezoidal block 5421 during the movement to the left, thereby driving the trapezoidal paddle 541 to move to the left and at the same time making the trapezoidal paddle 541 rise to a certain height. During the movement of the trapezoidal paddle 541 to the upper left, its two horizontal sections will be inserted into the notch of the notched alloy ring to fine-tune the position of the notched alloy ring, thereby making the notch of the notched alloy ring face upward.

[0045] When the folding rod 53 moves to the upper left, the horizontal section above it will slide upward along the waist-shaped groove 512 on the one hand, and the horizontal section above the folding rod 53 will also move to the left relative to the rectangular sleeve 513 on the other hand. During this process, the reset spring 5142 is compressed. After the notch of the notch alloy ring is adjusted to the top by the trapezoidal paddle 541, the center rod 4 is pulled to the right to drive the rubber block 64 to move outward along the radial direction of the mounting tube 2 to clamp the notch alloy ring. Then the pressure on the folding rod 53 is released. Under the action of the reset spring 5142, the folding rod 53 moves to the right and resets, driving the trapezoidal paddle 541 to move away from the notch alloy ring. At the same time, the folding rod 53 is reset under the action of gravity of the push block 5422, so as to fine-tune the position of the notch alloy ring without affecting the welding process.

[0046] See also Fig. 9 The cooling mechanism 7 includes a connecting pipe 71, which is rotatably connected to the center of the left sealing plate 23. The left end of the connecting pipe 71 is rotatably connected to an air inlet pipe that continuously introduces cold air to the right. A ventilation groove 72 is opened from left to right inside the center rod 4. The right end of the connecting pipe 71 is slidably mounted on the center rod 4 and the two are connected to each other. An air outlet assembly 73 is commonly provided on the center rod 4, the spindle-shaped seat 61 and the mounting tube 2.

[0047] See also Fig. 9 and Fig.10 The air outlet assembly 73 includes an inner through groove 731, and the inner through groove 731 is evenly opened on the center rod 4 and the spindle-shaped seat 61 along the circumferential direction. The mounting tube 2 is evenly opened with an outer through groove 732 along the circumferential direction at a position located at the bottom of the annular groove 22 and different from the round rod 62.

[0048] During specific operation, the cold air introduced into the air inlet pipe enters the ventilation groove 72 along the connecting pipe 71, then enters the installation tube 2 along the inner groove 731, and is finally discharged from the outer groove 732 to the inner surface of the alloy ring or the notched alloy ring, thereby cooling the ring after welding is completed. On the one hand, it can reduce the stress caused by high temperature, and on the other hand, it can facilitate manual and quick removal of the welded ring to avoid burns.

[0049] See also Figure 4 The driving mechanism 8 includes a large gear 81, which is fixedly sleeved on the left end of the mounting tube 2. A small gear 82 is meshedly connected to the bottom of the large gear 81. The left end face of the small gear 82 is fixedly connected to a mounting rod 83. The mounting rod 83 is rotatably connected to the vertical section of the L-shaped plate 1 and is fixedly connected to the driving shaft of the external intermittent motor.

[0050] During specific operation, the external intermittent motor drives the installation rod 83 to rotate, and then drives the large gear 81 to rotate intermittently through the small gear 82. When the large gear 81 rotates, it drives the installation tube 2, the round rod 62 and the rubber block 64 to drive the alloy ring to rotate synchronously, so that the laser welding machine can adjust the position of the complete alloy ring and facilitate the operator to stick the broken diamonds on the surface of the complete alloy ring when the alloy ring is stationary. In this process, due to the decrease in the transmission ratio between the small gear 82 and the large gear 81, the rotation speed of the large gear 81 is slower than the rotation speed of the small gear 82, so that the alloy ring runs at a slower speed during the processing, and sufficient time is reserved for the welding operation of the laser welding machine.
