Description

Technical Field

[0001] This invention relates to the field of jewelry processing technology, and in particular to a bead chain engraving machine and a bead chain processing method. Background Technology

[0002] Throughout history, people have created and worn jewelry chains of various styles, characteristics, and designs to enhance the beauty of the human body. As people's living standards continue to improve, the demands for jewelry chain designs are also increasing to meet individual needs.

[0003] A beaded chain is a type of jewelry chain composed of multiple interconnected beads. The earliest beaded chains featured smooth, simple beads; however, as living standards improved and people's demand for personalization increased, the chains gradually evolved to include various styles of designs on the beads' surfaces to meet aesthetic requirements. In the process of shaping the beads, a beading machine is used to create patterns and achieve a better aesthetic effect. However, traditional beading machines have gradually revealed some unavoidable shortcomings in long-term practical use:

[0004] Firstly, the processing method is quite cumbersome, requiring each individual bead to be processed separately before being strung together into a complete jewelry chain. This process is not only lengthy and complex, but also greatly limits production efficiency, making it difficult to meet the current market's urgent demand for efficient production.

[0005] Secondly, traditional engraving machines have significant shortcomings in terms of shaping precision. On the one hand, due to poor clamping stability of the beads, it is difficult to ensure precise positioning and stable operation when processing patterns on the surface of the beads, resulting in a significant reduction in the processing precision of the patterns and failing to provide a stable and reliable guarantee of engraving quality for the product. On the other hand, it is difficult to precisely control the processing force of the cutting tool on the beads, which results in uneven engraving force on each bead, leading to subtle but not negligible differences in the engraving shape of the beads. This seriously affects the overall aesthetic harmony and refinement of the jewelry chain, weakening the product's competitiveness in the market. Summary of the Invention

[0006] In view of this, the technical problem to be solved by the present invention is to provide a bead chain engraving machine and a bead chain processing method, which can continuously engrave and form the beads of the bead chain, improve forming efficiency, reduce labor costs, and at the same time ensure uniform engraving force and improve processing accuracy.

[0048] This application discloses a bead chain engraving machine and a bead chain processing method; wherein, the bead chain engraving machine includes a frame; two chain clamping devices arranged opposite each other along the X direction are installed on the frame, and an engraving unit is installed on the frame and can rotate around the Z axis, the engraving unit being disposed between the two chain clamping devices; the moving direction of the bead chain is defined as the X direction; the two chain clamping devices are mutually adapted to fix one bead, sequentially deliver multiple beads, and drive the bead chain to rotate around the X axis; the engraving unit is used to form a diamond pattern on the beads.

[0049] The pattern-making unit includes a Z-axis rotary mechanism mounted on the frame. The center of the Z-axis rotary mechanism is located between two chain devices. Two pattern-making devices are mounted on the Z-axis rotary mechanism and arranged opposite each other along the Y direction. The Z-axis rotary mechanism is used to drive the two pattern-making devices to rotate around the Z-axis. The Z-axis rotary mechanism can adjust the feed direction of the pattern-making devices to meet the forming requirements of diamond patterns.

[0050] The two engraving devices have the same structure. The engraving device includes an engraving mechanism, a Y-axis rotation mechanism, and a Y-axis translation mechanism.

During this process, the feed direction and feed angle of the engraving devices can be adjusted multiple times as needed until a diamond pattern is formed on the surface of the bead.

[0052] In this process, firstly, it changes the traditional method of forming only one bead at a time, allowing beads in an entire bead chain to be formed sequentially without the need for later chain threading, thus improving forming efficiency and reducing labor costs. Secondly, the use of two chain clamping devices improves the stability of bead clamping, ensuring precise positioning and stable operation, and improving the processing accuracy of patterns. Simultaneously, the use of two engraving devices positioned opposite each other to engrave the beads simultaneously, once, or sequentially ensures uniform engraving force each time, improving the overall aesthetic harmony and refinement, as well as increasing bead forming efficiency and shortening the forming process.

[0053] This application also discloses a method for processing beaded chains. Based on the beaded chain engraving machine in this application, the chain beads can be continuously engraved to improve forming efficiency and reduce labor costs; at the same time, it ensures uniform engraving force and improves processing accuracy.

[0075] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0076] Example 1

[0077] like Figure 1 , Figure 2 As shown, the bead chain engraving machine of this application includes a frame 1; two chain clamping devices 2 arranged opposite each other along the X direction are mounted on the frame 1, and an engraving unit 3 is mounted on the frame 1 and can rotate around the Z axis, the engraving unit 3 being disposed between the two chain clamping devices 2; the movement direction of the bead chain is defined as the X direction. The engraving unit 3 is used to form a diamond pattern on the surface of the chain beads.

[0078] The two chain clamping devices 2 are mutually adapted to fix a chain bead, sequentially deliver multiple chain beads, and drive the bead chain to rotate around the X-axis. The engraving unit 3 includes a Z-axis rotation mechanism 4 mounted on the frame 1. The center of the Z-axis rotation mechanism 4 is located between the two chain clamping devices 2. Two engraving devices 5 are mounted on the Z-axis rotation mechanism 4 and arranged opposite each other along the Y-axis. The Z-axis rotation mechanism 4 is used to drive the two engraving devices 5 to rotate around the Z-axis.

[0079] In this application, the center of the bead, the center between the two chain devices 2, and the center of the two engraving devices 5 all coincide.

[0080] The two engraving devices 5 have the same structure. Each engraving device 5 includes an engraving mechanism 51, a Y-axis rotation mechanism 52, and a Y-axis translation mechanism 53. The engraving mechanism 51 is used to process the surface of the chain beads. The engraving mechanism 51 is installed at the actuating end of the Y-axis rotation mechanism 52. The Y-axis rotation mechanism 52 is used to drive the engraving mechanism 51 to rotate around the Y-axis. The Y-axis rotation mechanism 52 is installed at the actuating end of the Y-axis translation mechanism 53. The Y-axis translation mechanism 53 is used to drive the Y-axis rotation mechanism 52 and the engraving mechanism 51 together to move closer to or away from the chain beads.

[0081] When engraving is required on the beads, the bead chain is first manually passed through two clamping devices 2, so that one bead is positioned between the two clamping devices 2; the two clamping devices 2 rotate in the same direction around the X-axis, causing the entire bead chain to rotate; the upstream clamping device 2 moves one bead upstream and then clamps the chain shaft upstream of the current bead; the downstream clamping device 2 opens its clamping end and is in a released state; the upstream clamping device 2 clamps the chain shaft and moves one bead downstream, so that the upstream bead is moved to the position between the two clamping devices 2. Between; the downstream clamping device 2 closes the clamping end to clamp the chain shaft on the downstream side of the current chain bead; the Z-axis rotation mechanism 4 drives the two engraving devices 5 to rotate around the Z-axis to adjust their feed direction; the Y-axis rotation mechanism 52 adjusts the feed angle of the engraving mechanism 51; the Y-axis translation mechanism 53 drives the engraving mechanism 51 to move closer to the chain bead to engrave it; during this process, the feed direction of the engraving device 5 and the feed angle of the engraving mechanism 51 can be adjusted multiple times as needed; until the surface of the chain bead is formed with a diamond pattern.

[0082] In this process, firstly, it changes the traditional method of forming only one bead at a time, allowing beads in an entire bead chain to be formed sequentially without the need for later chain threading, thus improving forming efficiency and reducing labor costs. Secondly, the use of two chain clamping devices 2 improves the clamping stability of the beads, ensuring precise positioning and stable operation, and improving the processing accuracy of the patterns. Simultaneously, the use of two engraving devices 5, positioned opposite each other, to engrave the beads simultaneously, once, or sequentially ensures uniform engraving force each time, improving the overall aesthetic harmony and refinement, as well as increasing the forming efficiency of the beads and shortening the forming process.

[0083] like Figures 1 to 7 As shown in the diagram, in this application, the bead chain needs to be rotated to cooperate with the engraving device 5 to form patterns. The rotation of the bead chain is accomplished by the chain clamping device 2. The chain clamping device 2 includes a clamping mechanism 21, an X-axis rotation mechanism 22, and an X-axis translation mechanism 23. The clamping mechanism 21 can rotate around the X-axis. The interior of the clamping mechanism 21 is hollow and has a channel 216 for moving the bead chain. The clamping mechanism 21 is used to clamp the chain shaft between two adjacent beads. The clamping mechanism 21 is driven to the X-axis rotation mechanism 22. The X-axis rotation mechanism 22 is used to drive the clamping mechanism 21 to clamp the chain shaft between two adjacent beads, thereby causing the bead chain to rotate around the X-axis. The X-axis rotation mechanism 22 is installed at the moving end of the X-axis translation mechanism 23. The X-axis translation mechanism 23 is used to drive the X-axis rotation mechanism 22 and the clamping mechanism 21 to reciprocate together along the X-direction.

[0084] The clamping mechanism 21 includes a clamping seat 211, a clamping guide tube 212, a clamping assembly 213, a clamping sleeve 214, and a clamping cylinder 215. The clamping guide tube 212 is rotatably mounted on the clamping seat 211. The clamping guide tube 212 is arranged along the X direction and has a hollow structure. A material channel 216 is provided inside the clamping guide tube 212. Several mounting blocks 217 arranged around its axis are provided at one end of the clamping guide tube 212. Preferably, the mounting blocks 217 are integrally formed with the clamping guide tube 212, and the number of mounting blocks 217 is four.

[0085] The clamping assembly 213 is coaxially arranged with the clamping guide tube 212. The clamping assembly 213 includes a plurality of clamping claws 218 arranged around its axis. The clamping claws 218 are rotatably mounted between two adjacent mounting blocks 217. The inner side of the clamping claws 218 is provided with an arc-shaped clamping surface 2181 coaxially arranged with the clamping guide tube 212. Preferably, the arc-shaped clamping surface 2181 can reciprocate along the radial direction of the clamping guide tube 212 to clamp and release the chain shaft.

[0086] The gripper 218 is adapted to the gripping sleeve 214; the gripping sleeve 214 is coaxially sleeved on the outside of the gripping guide tube 212, and a return spring 219 is provided between one end of the gripping sleeve 214 and the gripping seat 211. The inside of the gripping sleeve 214 is provided with a receiving groove 2141 and a sleeve clamping inclined surface 2142; the outer wall of the gripper 218 is provided with a gripper release inclined surface 2182 adapted to the receiving groove 2141 and a gripper clamping inclined surface 2183 adapted to the sleeve clamping inclined surface 2142.

[0087] The actuating end of the clamping cylinder 215 abuts against the outer wall of the clamping sleeve 214, and the clamping cylinder 215 is used to drive the clamping sleeve 214 to move away from the clamping assembly 213. An annular boss is provided on the outer wall of the clamping sleeve 214; along the X direction, the actuating end of the clamping cylinder 215 and the return spring 219 are respectively located on both sides of the annular boss.

[0088] When the clamping cylinder 215 moves along the X direction towards the side closer to the clamping seat 211, it drives the clamping sleeve 214 to move in the same direction and compresses the return spring 219. At this time, the inner wall of the clamping sleeve 214 abuts against the jaws 218, causing the arc-shaped clamping surfaces 2181 of several jaws 218 to move outward along the radial direction of the clamping guide tube 212, releasing the chain shaft. When the clamping cylinder 215 moves along the X direction away from the clamping seat 211, the return spring 219 pushes the clamping sleeve 214 to move in the same direction, causing the sleeve clamping inclined surface 2142 to abut against the jaw clamping inclined surface 2183 and continue to move, causing the arc-shaped clamping surfaces 2181 of several jaws 218 to move inward along the radial direction of the clamping guide tube 212, clamping the chain shaft.

[0089] Preferably, a cleaning pipe 24 is installed on the clamping seat 211 along the X direction. One end of the cleaning pipe 24 is connected to an external high-pressure air source, and the other end is bent toward the clamping assembly 213 to blow air to clean the material residue after the material is shaped.

[0090] In this application, the chain shaft needs to be loaded and unloaded, and this action is completed by the X-axis translation mechanism. The X-axis translation mechanism 23 includes an X-axis linear module 231 mounted on the frame 1, which is driven and connected to the X-axis translation motor 232; the X-axis rotation mechanism 22 is mounted on the moving end of the X-axis linear module 231. In order to ensure the translation accuracy of the clamping mechanism 21 driven by the X-axis rotation mechanism 22, the X-axis translation mechanism 23 also includes an X-axis translation sensing component 233. The X-axis translation sensing component 233 includes several X-axis translation sensors and an X-axis translation detection plate. The X-axis translation detection plate is mounted on the clamping seat 211 and moves with the clamping seat 211. Several X-axis translation sensors are sequentially mounted on the frame 1 along the X-axis.

[0091] The X-axis rotation mechanism 22 includes an X-axis rotation motor 221. The X-axis rotation motor 221 and the clamping seat 211 are both mounted on the actuating end of the X-axis linear module 231. The X-axis rotation motor 221 and the clamping guide tube 212 are driven and connected through an X-axis rotation synchronous pulley belt assembly. The X-axis rotation motor 221 drives the clamping guide tube 212 to rotate around the X-axis.

[0092] like Figure 1 , Figure 2 , Figure 8 As shown, the engraving mechanism 51 includes a tool mounting bracket 511, a tool 512, and an engraving motor 513. The tool 512 is a disc tool, which is rotatably mounted on the tool mounting bracket 511. The engraving motor 513 is mounted on the tool mounting bracket 511, and the engraving motor 513 and the tool 512 are connected by an engraving synchronous pulley belt assembly. In this application, the tool 512 for engraving the chain beads is a disc tool, which is used to meet the requirement of forming a diamond pattern on the chain beads. Specifically, the disc tool engraves the chain beads by a line machining method. After being driven to rotate by the engraving motor 513 and adjusted by the Y-axis rotation mechanism 52, the disc tool can process the four sides of the diamond pattern separately. Thus, after multiple processing, one or more complete diamond patterns are formed. Traditional engraving machines do not use disc cutting tools for engraving, therefore, traditional engraving machines cannot complete the formation of diamond patterns.

[0093] The Y-axis rotary mechanism 52 includes a rotary seat 521, a Y-axis rotating shaft, and a Y-axis rotary motor 522. The rotary seat 521 is installed on the actuating end of the Y-axis translation mechanism 53. The Y-axis rotating shaft (obscured in the figure) is rotatably installed in the rotary seat 521, and one end of the Y-axis rotating shaft is connected to the cutting tool mounting bracket 511. The Y-axis rotary motor 522 is installed on the rotary seat 521, and the other end of the Y-axis rotating shaft is driven by the Y-axis rotary synchronous pulley belt assembly.

[0094] The Y-axis rotary motor 522 drives the Y-axis to rotate, causing the tool mounting bracket 511 and the tool 512 mounted thereon to rotate together around the Y-axis, thereby adjusting the tilt angle of the tool 512. In this application, to ensure that the Y-axis rotary motor 522 drives the tool 512 to accurately return to the origin, the Y-axis rotary mechanism 52 also includes a Y-axis rotary sensing assembly 523. The Y-axis rotary sensing assembly 523 includes one or more Y-axis rotary sensors and at least one Y-axis rotary detection plate. The Y-axis rotary sensors are mounted on the rotary base 521, and the Y-axis rotary detection plate is mounted on the driven wheel of the Y-axis rotary synchronous pulley assembly. When one Y-axis rotary sensor is used in conjunction with the Y-axis rotary detection plate, the origin position of the tool 512 can be determined; when multiple Y-axis rotary sensors are used in conjunction with the Y-axis rotary detection plate, the origin position and tilt angle of the tool 512 can be determined.

[0095] The Y-axis translation mechanism 53 includes a Y-axis linear module 531 and a Y-axis translation motor 532; both the Y-axis linear module 531 and the Y-axis translation motor 532 are mounted on the actuating end of the Z-axis rotary mechanism 4. In this application, in order to ensure the translation accuracy of the Y-axis translation mechanism 53 driving the embroidery mechanism 51, the Y-axis translation mechanism 53 also includes a Y-axis translation sensing component 533, which includes several Y-axis translation sensors and a Y-axis translation detection plate. The Y-axis translation detection plate is mounted on the rotary base 521 and moves with the rotary base 521. The several Y-axis translation sensors are sequentially mounted on the Z-axis rotary mechanism 4.

[0096] The Z-axis rotary mechanism 4 includes a rotary platform 41 and a rotary beam 42. The rotary platform 41 is driven by the Z-axis rotary motor 43, and the rotary beam 42 is installed at the moving end of the rotary platform 41. The Z-axis rotary motor 43 drives the rotary beam 42 to rotate around the Z-axis through the rotary platform 41. Two embroidery devices 5 are respectively installed at both ends of the rotary beam 42 and are arranged opposite to each other, thereby driving the two embroidery devices 5 to rotate around the Z-axis simultaneously. To ensure that the slewing beam 42 accurately drives the two embellishment devices 5 back to the origin, the Z-axis slewing mechanism 4 also includes one or more Z-axis slewing sensors. The Z-axis slewing sensors are mounted on the frame 1 and are adapted to the slewing beam 42. When one Z-axis slewing sensor is used in conjunction with the slewing beam 42, the slewing beam 42 can be used to determine the origin position of the embellishment device 5. When multiple Z-axis slewing sensors are used, the multiple Z-axis slewing sensors are arranged around the circumference of the slewing platform 41. The multiple Z-axis slewing sensors, in conjunction with the slewing beam 42, can determine the origin position and slewing angle of the embellishment device 5.

[0097] like Figure 1 , Figure 2 , Figure 9 , Figure 10 As shown in the present application, in order to satisfy the chain feeding and unfeeding action of the bead chain, so that the chain clamping device 2 and the engraving device 5 cooperate with each other to form a number of chain beads in sequence, the frame 1 is equipped with a chain feeding device 7 and a chain taking device 8, which are controlled by the same chain feeding and unfeeding rotation mechanism 6. The chain feeding device 7 and the chain taking device 8 are arranged opposite to each other along the X direction. The chain feeding device 7 is arranged along the X direction outside one of the chain clamping devices 2, and the chain taking device 8 is arranged along the X direction outside the other chain clamping device 2. The chain taking device 8 is equipped with a chain taking drive mechanism 9, which is controlled by the chain taking power mechanism.

[0098] The chain feeding device 7 and the chain take-up device 8 have the same structure. The chain take-up device 8 includes a chain take-up bracket 81, a chain conveying guide pipe 82, a material tray seat 83, and a material tray 84. Preferably, the chain take-up bracket 81 is mounted on the frame 1. The chain conveying guide pipe 82 has a hollow structure, is arranged along the X direction and rotatably mounted on the chain take-up bracket 81, and is coaxially arranged with the chain clamping device 2. The material tray seat 83 is fixed to one end of the chain conveying guide pipe 82 and is penetrated by the chain conveying guide pipe 82. The material tray 84 is detachably rotatably mounted on the material tray seat 83. During chain feeding and take-up, the bead chains pass through their respective chain conveying guide pipes 82 and are wound onto the material tray 84.

[0099] The chain-retracting rotation mechanism 6 drives the corresponding material tray seats 83 in the chain-retracting device 7 and chain-retracting device 8 to rotate. Its rotation direction and speed are consistent with the rotation direction and speed of the clamping guide tube 212, thus meeting the requirement of driving the entire bead chain to rotate. The chain-retracting rotation mechanism 6 includes a chain-retracting rotation motor, a chain-retracting synchronous pulley belt assembly, and a chain-retracting rotating shaft. The chain-retracting rotation motor drives the chain-retracting rotating shaft to rotate around the X-axis through the chain-retracting synchronous pulley belt assembly. The two ends of the chain-retracting rotating shaft are respectively driven to the material tray seats 83 in the chain-retracting device 7 through the chain-retracting synchronous pulley belt assembly and to the material tray seats 83 in the chain-retracting device 8 through the chain-retracting synchronous pulley belt assembly, so as to realize the synchronous rotation of the two material tray seats 83.

[0100] In this application, the chain take-up drive mechanism 9 includes a drive pulley 91, a driven pulley 92, a reversing pulley set 93, and a chain take-up belt 94; the drive pulley 91 is rotatably mounted on the chain conveyor guide pipe 82 and drivenly connected to the chain take-up power mechanism, the driven pulley 92 is connected to the material tray 84, the reversing pulley set 93 is mounted on the material tray seat 83 and located between the drive pulley 91 and the driven pulley 92, and the chain take-up belt 94 is tensioned between the drive pulley 91, the driven pulley 92, and the reversing pulley set 93.

[0101] The chain release does not require a power mechanism to drive the material tray 84 corresponding to the chain release device 7 to rotate. The chain retraction only requires a chain retraction power mechanism to drive the material tray 84 corresponding to the chain retraction device 8 to rotate, which can complete the chain release, X-direction movement and chain retraction of the entire chain.

[0102] In this application, the chain winding device 8 also includes a chain winding mechanism, which is used to evenly wind the formed bead chain onto the material tray 84.

[0103] The chain mechanism includes a chain shaft, a guide shaft, a chain seat, and a chain timing pulley assembly. The chain shaft is rotatably mounted on the material tray seat 83, and the chain shaft is evenly provided with forward and reverse threads around its axis, which are interleaved. The guide shaft is mounted on the material tray seat 83 and is arranged in the same direction as the chain shaft. The chain seat is slidably mounted on the guide shaft and is adapted to both the forward and reverse threads of the chain shaft. The chain shaft is driven to the material tray 84 through the chain timing pulley assembly.

[0104] When the material tray 84 rotates, the cloth chain shaft is driven to rotate together through the cloth chain synchronous pulley assembly. The cloth chain seat is driven to move in one direction through the forward spiral thread to cloth chain. When the cloth chain seat moves along the axial direction of the cloth chain shaft and comes into contact with the material tray seat 83, the cloth chain seat is blocked and then engages with the reverse spiral thread to move in the opposite direction to continue cloth chain. In this way, the cloth chain seat moves back and forth along the axial direction of the cloth chain shaft, so that the formed bead chain is evenly wound on the material tray 84.
