[0002] In the field of jewelry manufacturing, the drilling process in traditional gold bead processing has always been a delicate and challenging task. For a long time, this step has mainly relied on manual operation. The craftsman usually holds the gold bead steadily with one hand to ensure that it will not shift due to vibration during the drilling process, while the other hand flexibly controls the drilling tool to perform precise rotation and drilling operations on the gold bead.

[0003] However, the stability and precision of human hands are limited, and it is difficult to completely avoid slight deviations in the drilling position or improper depth control, which increases the rate of defective products.

[0053] Combine the following Figures 1 to 8 , describing an automated system for opening a mold and removing gold sheets according to an embodiment of the present invention.

[0054] An automatic system for opening a mold and taking out a gold sheet, comprising a lower mold mechanism 2, an upper mold mechanism 3 and a gold sheet opening mechanism 4 arranged on a frame;

[0055] The upper mold mechanism 3 is located above the lower mold mechanism 2, and the gold sheet opening mechanism 4 is installed at both the front and rear ends of the lower mold mechanism 2. The upper mold mechanism 3 and the lower mold mechanism 2 jointly clamp the gold beads, and the gold sheet opening mechanism 4 is used to drill holes in the gold beads and bring out the gold sheets.

[0056] The operation process of an automatic system for opening molds and taking out gold flakes in this scheme is as follows: the worker places the gold bead on the lower mold mechanism 2, and then starts the upper mold mechanism 3, which presses the gold bead downward, so that the upper mold mechanism 3 and the lower mold mechanism 2 clamp the gold bead together to prevent the gold bead from moving during the processing. Then, the gold flake opening mechanisms located on the front and rear sides are started to drill holes on the front and rear sides of the gold bead and take out the gold flakes inside the gold bead, solving the problem of high labor intensity and difficulty in taking out the gold flakes.

[0057] The upper die mechanism 3 includes an upper die pressing plate 31, an upper die lifting module 32, an upper die pressing member 33 and a gold sheet removing assembly 34;

[0058] The mounting end of the upper die lifting module 32 is vertically mounted on the frame, the upper die pressing plate 31 is mounted on the movable end of the upper die lifting module 32, and the upper die pressing member 33 is disposed at the bottom of the upper die pressing plate 31;

[0059] The lower die mechanism 2 includes a lower die pressing member, and the upper die pressing member 33 is arranged opposite to the lower die pressing member;

[0060] The gold sheet taking components 34 are installed on both the front and rear sides of the upper die lifting module 32 , and the upper die pressing member 33 is located between the two gold sheet taking components 34 .

[0061] The upper die pressing plate 31 can be smoothly and accurately lowered to a predetermined position through the precise control of the upper die lifting module 32. The relative arrangement of the upper die pressing member 33 and the lower die pressing member ensures that the gold beads are firmly and stably clamped during the processing, effectively preventing displacement or deformation during the processing, thereby improving the processing accuracy and product consistency.

[0062] The gold sheet taking components 34 are installed on both the front and rear sides of the upper mold pressing plate 31. This design not only optimizes the spatial layout, but also realizes the high efficiency of gold sheet separation and recovery. When the gold sheet opening mechanism 4 completes the drilling process and takes out the gold sheet, the gold sheet taking components 34 can quickly and accurately clamp the gold sheet on the gold sheet opening mechanism 4, thereby improving production efficiency.

[0063] The modular design of the upper die mechanism 3 makes it easy to replace and maintain each component, and also enhances the flexibility of the system. Gold beads of different specifications or shapes can be adapted by replacing the upper die pressing member 33, without the need for large-scale transformation of the entire system, thus reducing the transformation cost and time.

[0064] The upper mold lifting module 32 includes an upper mold lifting driving component 321, an upper mold lifting slide rail and an upper mold lifting slider 323. The upper mold lifting slide rail is vertically installed on the frame. The upper mold lifting slider 323 is slidably connected to the upper mold lifting slide rail. The upper mold lifting driving component 321 is used to drive the upper mold lifting slider 323 to slide. The upper mold lifting slider 323 is vertically connected to the upper mold pressing plate 31.

[0065] It is worth noting that the upper die lifting drive member 321 is preferably a motor. The upper die lifting drive member 321 drives the upper die lifting slider 323 to move on the upper die lifting slide rail, and the upper die lifting slider 323 can drive the upper die pressing plate 31 to move in the vertical direction, ensuring that the gold beads can be subjected to uniform and constant pressure during the processing, thereby improving the processing accuracy and product quality.

[0066] The gold sheet removing assembly 34 includes a gold sheet lifting driving component 341, a gold sheet lifting rail 342, a gold sheet lifting slider 343 and a gold sheet clamping component 344. The gold sheet lifting rail 342 is vertically installed on the upper mold lifting slider 323, and the gold sheet lifting slider 343 is slidably connected to the gold sheet lifting rail 342. The gold sheet lifting driving component 341 is used to drive the gold sheet lifting slider 343 to move, and the gold sheet lifting slider 343 is fixedly connected to the gold sheet clamping component 344.

[0067] It is worth noting that the gold sheet lifting driving member 341 is preferably a cylinder. When the gold sheet opening mechanism 4 takes out the gold sheet, the gold sheet lifting driving member 341 drives the gold sheet lifting slider 343 to move on the gold sheet lifting slide rail 342, and the gold sheet lifting slider 343 can drive the gold sheet clamping member 344 to move downward, so that the gold sheet clamping member 344 can clamp the gold sheet downward, ensuring that the gold sheet can be quickly and accurately clamped and extracted after drilling, avoiding the omission or damage of the gold sheet, and improving the production efficiency and product quality.

[0068] The gold sheet cutting mechanism 4 includes a bottom plate 41, a bottom plate movable module 42, a drilling module 43, a gold sheet taking out module 44, a three-claw tool 45 and a screw thread needle 46;

[0069] The mounting end of the bottom plate movable module 42 is mounted on the frame, the movable end of the bottom plate movable module 42 is fixedly connected to the bottom plate 41, and the frame is slidably connected to the bottom plate 41;

[0070] The drilling module 43 and the gold sheet bringing out module 44 are both located at the top of the base plate 41, the movable end of the drilling module 43 is connected to the three-claw tool 45, and the movable end of the gold sheet bringing out module 44 is connected to the screw thread needle 46, the tip of the screw thread needle 46 is penetrated inside the three-claw tool 45, the drilling module 43 is used to drive the three-claw tool 45 to rotate and expand or contract outward, the three-claw tool 45 is used to drill holes in the gold beads, the gold sheet bringing out module 44 is used to drive the screw thread needle 46 to rotate and move back and forth, and the screw thread needle 46 is used to bring out the gold sheets inside the gold beads.

[0071] The gold sheet cutting mechanism 4 integrates the functions of the drilling module 43 and the gold sheet taking-out module 44, thereby realizing efficient drilling of gold beads and subsequent accurate separation and taking-out of gold sheets. The drilling module 43 drives the three-claw tool 45 to rotate and expand outward, ensuring that the drilling process is fast and accurate; while the gold sheet taking-out module 44 utilizes the rotation and forward and backward movement of the screw thread needle 46 to effectively separate and take out the loose gold sheets from the gold beads after drilling, greatly improving production efficiency.

[0072] The three-claw tool 45 and the screw thread needle 46 are precisely matched to ensure the accuracy and consistency of the drilling and gold sheet separation process. The outward expansion force of the three-claw tool 45 can evenly act on the surface of the gold bead to avoid deviation or deformation during the drilling process; while the rotation of the screw thread needle 46 can penetrate into the gap between the gold sheet and the gold bead, further promoting the separation of the gold sheet, thereby improving the processing accuracy and product quality.

[0073] The drilling module 43 includes a tool driving assembly 431, a tool expansion assembly 432 and a tool rotation assembly 433;

[0074] The driving end of the tool driving assembly 431 is connected to the tool expansion assembly 432. The tool driving assembly 431 is used to provide a power source for the tool expansion assembly 432. The tool expansion assembly 432 is used to drive the three-claw tool 45 to expand or contract. The tool rotation assembly 433 is used to drive the three-claw tool 45 to rotate.

[0075] When the three-claw tool 45 rotates under the action of the tool rotating assembly 433, the tip of the three-claw tool 45 continuously contacts the surface of the gold bead and applies cutting force. At the same time, the three-claw tool 45 moves forward under the action of the tool driving assembly 431, so that the cutting edge can gradually penetrate into the gold bead to form continuous holes.

[0076] The drilling module 43 realizes precise control of the three-claw tool 45 by integrating the tool drive assembly 431, the tool expansion assembly 432 and the tool rotation assembly 433. The tool drive assembly 431 provides a stable and reliable power source for the tool expansion assembly 432, ensuring the accuracy of tool expansion or contraction; while the tool rotation assembly 433 drives the three-claw tool 45 to rotate at a set speed, ensuring the smoothness and efficiency of the drilling process, and reducing errors and scrap rates caused by improper operation.

[0077] The tool rotating assembly 433 includes a rotating sleeve 4331, a first tool rotating gear 4332, a second tool rotating gear 4333, a tool rotating chain and a tool rotating driving member 4334;

[0078] The rotating sleeve 4331 is rotatably installed on the base plate 41, and the length direction of the rotating sleeve 4331 is the front-to-back direction. The end of the rotating sleeve 4331 is connected to the three-claw tool 45. The tool rotation driving member 4334 is installed on the base plate 41. The output end of the tool rotation driving member 4334 is fixedly connected to the first tool rotation gear 4332. The end of the rotating sleeve 4331 away from the three-claw tool 45 is fixedly sleeved with the second tool rotation gear 4333. The tool rotation chain is sleeved on the first tool rotation gear 4332 and the second tool rotation gear 4333.

[0079] It is worth noting that the tool rotation drive member 4334 is preferably a motor. When the tool rotation drive member 4334 is started, it can drive the first tool rotation gear 4332 to rotate, the first tool rotation gear 4332 can drive the second tool rotation gear 4333 and the tool rotation chain to rotate, the second tool rotation gear 4333 can drive the rotating sleeve 4331 to rotate, so that the rotating sleeve 4331 can drive the three-claw tool 45 to rotate.

[0080] In addition, a splash shield is provided at the end of the rotating sleeve 4331 close to the three-claw tool 45, and the splash shield ring is installed on the outside of the three-claw tool 45. When the three-claw tool 45 starts drilling, it can prevent fragments on the gold beads from splashing outward, thereby effectively collecting metal fragments.

[0081] The tool expansion assembly 432 includes a tool expansion slider 4321, a tool expansion guide block 4322 and a tool expansion sleeve 4323. A plurality of tool slide grooves are provided on one side of the rotating sleeve 4331 close to the three-claw tool 45. The plurality of tool expansion sliders 4321 are respectively slidably connected to the plurality of tool slide grooves and correspond one to one. The tool expansion slider 4321 is fixedly connected to the three-claw tool 45.

[0082] One end of the tool expansion sleeve 4323 close to the three-claw tool 45 is movably inserted into the interior of the rotating sleeve 4331, and the end of the tool expansion sleeve 4323 is threadedly connected to the tool expansion guide block 4322, and one end of the tool expansion guide block 4322 close to the tool expansion sleeve 4323 is movably inserted into the interior of the rotating sleeve 4331;

[0083] The tool expansion slider 4321 is provided with an inclined expansion slide rail 4324, the tool expansion guide block 4322 is slidably connected to the plurality of expansion slide rails 4324 respectively, the driving end of the tool drive assembly 431 is connected to the tool expansion sleeve 4323, the tool drive assembly 431 is used to drive the tool expansion sleeve 4323 and the tool expansion guide block 4322 to move forward and backward, and the tool expansion guide block 4322 is used to guide the plurality of tool expansion sliders 4321 to move back and forth on the tool slide groove;

[0084] The expansion slide rail 4324 is inclined from front to back toward the bottom, and the tool expansion guide block 4322 is provided with an inclined surface, and the inclined surface is inclined from front to back toward the bottom.

[0085] The tool drive assembly 431 is started, and the tool drive assembly 431 can drive the tool expansion sleeve 4323 to move forward, and the tool expansion sleeve 4323 drives the tool expansion guide block 4322 to move forward. Since the tool expansion guide block 4322 is provided with an inclined surface, and the plurality of expansion slide rails 4324 are all slidably connected to the tool expansion guide block 4322, the plurality of tool expansion slide blocks 4321 move outward under the guidance of the inclined surface, thereby ensuring that the three-claw tool 45 expands outward, thereby drilling the surface of the gold bead.

[0086] Similarly, when the tool drive assembly 431 drives the tool expansion sleeve 4323 to move backward, the multiple tool expansion slide blocks 4321 move inward under the guidance of the tool expansion guide block 4322, thereby retracting the three-claw tool 45 to complete the drilling process.

[0087] Among them, by adjusting the movable range of the tool expansion sleeve 4323, the expansion range of the three-claw tool 45 can be changed to meet the processing requirements of workpieces with different diameters.

[0088] In addition, the tool expansion slider 4321 is slidably connected to the tool slide groove, which can ensure the stable clamping of the three-jaw tool 45 when rotating at high speed or subjected to large cutting force, effectively preventing the three-jaw tool 45 from loosening or offset, thereby improving the processing accuracy and finished product quality.

[0089] The tool driving assembly 431 includes a tool movable driving member 4311, a tool driving slider 4312 and a tool driving slide rail 4313;

[0090] The bottom plate 41 is horizontally mounted with the tool driving rail 4313, the length direction of the tool driving rail 4313 is the front-back direction, the tool driving slider 4312 is slidably connected to the tool driving rail 4313, and the tool driving slider 4312 is connected to the tool expansion sleeve 4323;

[0091] The movable tool driving member 4311 is installed on the bottom plate 41 , and the output end of the movable tool driving member 4311 is fixedly connected to the tool driving slider 4312 .

[0092] It is worth noting that the tool movable driving member 4311 is preferably a cylinder. When the tool movable driving member 4311 is started, the tool movable driving member 4311 drives the tool driving slider 4312 to move on the tool driving slide rail 4313, so that the tool driving slider 4312 can drive the tool expansion sleeve 4323 to move in the front-back direction, thereby ensuring that the tool expansion sleeve 4323 can drive the three-claw tool 45 to expand or contract.

[0093] Among them, the structure of the tool drive assembly 431 enables the driving force to be quickly and fully transmitted to the tool expansion sleeve 4323, which can effectively reduce the complexity and energy loss of the transmission chain.

[0094] The sequin removal module 44 includes a pin drive assembly 441, a pin rotation assembly 442 and a buffer assembly 443. The pin drive assembly 441 is used to drive the screw thread needle 46 to move forward and backward, the pin rotation assembly 442 is used to drive the screw thread needle 46 to rotate, and the buffer assembly 443 is used to reduce the forward impact force of the screw thread needle 46.

[0095] The ejector drive assembly 441 can accurately control the screw thread needle 46 to move forward and backward at the appropriate time and speed. At the same time, the ejector rotation assembly 442 can drive the screw thread needle 46 to rotate. The rotation of the screw thread needle 46 effectively breaks the adsorption force or binding force between the gold sheet and the gold bead, so that the gold sheet can be completely and smoothly separated, thereby improving the quality and usability of the gold sheet.

[0096] The buffer component 443 can effectively alleviate the impact force that may be generated when the screw needle 46 is pushed forward, and also reduce the risk of damage to the gold sheet due to excessive impact force, thereby ensuring the integrity and high quality of the gold sheet.

[0097] The ejector drive assembly 441 includes an ejector movable drive member 4411, an ejector drive slider 4412 and an ejector drive slide rail 4413. The ejector drive slide rail 4413 is horizontally installed on the base plate 41. The length direction of the ejector drive slide rail 4413 is the front-to-back direction. The ejector drive slider 4412 is slidably connected to the ejector drive slide rail 4413. The ejector rotating assembly 442 and the buffer assembly 443 are both installed on the ejector drive slider 4412.

[0098] It is worth noting that the ejector movable driving member 4411 is a cylinder. When the ejector movable driving member 4411 is started, the ejector movable driving member 4411 drives the ejector driving slider 4412 to move on the ejector driving slide rail 4413, so that the ejector driving slider 4412 can drive the screw thread needle 46 to move in the front-rear direction.

[0099] The ejector rotating assembly 442 and the buffer assembly 443 are both located on the ejector driving slider 4412, which can ensure that the ejector rotating assembly 442 and the buffer assembly 443 can move forward or backward at the same time as the screw thread needle 46, so that when the screw thread needle 46 moves forward, the ejector rotating assembly 442 can drive the screw thread needle 46 to rotate at the same time. Moreover, when the tip of the screw thread needle 46 extends into the interior of the gold bead, the buffer assembly 443 can slow down and disperse the impact force of the screw thread needle 46 moving forward, making the forward movement of the screw thread needle 46 more stable and controllable.

[0100] Moreover, the range of motion of the screw needle 46 is limited by controlling the range of motion of the ejector pin driving slider 4412, thereby improving the stability and accuracy of the screw needle 46 in pushing the gold sheet, thereby avoiding the problem of gold sheet damage or incomplete separation caused by position deviation or uneven force.

[0101] The ejector rotating assembly 442 includes an ejector rotating driving member 4421, a first ejector rotating gear 4422, a second ejector rotating gear 4423, an ejector rotating sleeve 4424 and an ejector rotating chain;

[0102] The end of the screw thread needle 46 away from the three-claw tool 45 is fixedly connected to the thimble rotating sleeve 4424, and the thimble rotating sleeve 4424 is rotatably mounted on the top of the first thimble driving slider 4412. The outer wall of the thimble rotating sleeve 4424 is fixedly sleeved with the second thimble rotating gear 4423. The thimble rotating driving member 4421 is mounted on the thimble driving slider 4412. The driving end of the thimble rotating driving member 4421 is fixedly sleeved with the first thimble rotating gear 4422. The thimble rotating chain is sleeved on the first thimble rotating gear 4422 and the second thimble rotating gear 4423.

[0103] The end of the screw thread needle 46 away from the ejector rotating sleeve 4424 is movably inserted into the tool expansion sleeve 4323 , the tool expansion guide block 4322 and the three-claw tool 45 .

[0104] It is worth noting that the ejector rotating drive member 4421 is preferably a motor. When the ejector rotating drive member 4421 is started, the ejector rotating drive member 4421 drives the first ejector rotating gear 4422 to rotate, and the first ejector rotating gear 4422 drives the second ejector rotating gear 4423 and the ejector rotating chain to rotate, so that the second ejector rotating gear 4423 can drive the ejector rotating sleeve 4424 to rotate, and the ejector rotating sleeve 4424 drives the screw thread needle 46 to rotate. This transmission mode not only has high transmission efficiency, but also runs smoothly, reduces power loss and vibration, and reduces the occurrence of gold sheet damage caused by position deviation of the screw thread needle 46.

[0105] In addition, the present solution stipulates that the end of the screw needle 46 is located inside the three-claw tool 45, which can locate the position of the screw needle 46 and ensure that the screw needle 46 rotates forward to overcome the binding force between the gold sheet and the gold bead, thereby stably and effectively separating the gold sheet from the gold bead.

[0106] Moreover, the screw needle 46 is sequentially inserted into the interior of the tool expansion sleeve 4323 and the tool expansion guide block 4322, which can reduce the floor space occupied and facilitate the integration and coordinated work with the ejector drive assembly 441, the buffer assembly 443 and other structures, thereby improving the integration and working efficiency of the entire gold sheet bringing out module 44.

[0107] The buffer assembly 443 includes a buffer spring 4431 and a buffer block 4432. The buffer block 4432 is rotatably mounted on the ejector rotating sleeve 4424. One end of the buffer spring 4431 abuts against the ejector driving slider 4412, and the other end of the buffer spring 4431 abuts against the buffer block 4432. The buffer block 4432 is movably abutted against the tool expansion sleeve 4323.

[0108] Under the action of the ejector drive assembly 441, the screw thread needle 46 and the ejector rotating sleeve 4424 move forward, and the buffer block 4432 first contacts the tool expansion sleeve 4323. At this time, the ejector rotating sleeve 4424 continues to move forward, causing the buffer spring 4431 sleeved on the ejector rotating sleeve 4424 to deform, and the elastic deformation of the buffer spring 4431 absorbs and disperses the impact force, making the forward movement of the screw thread needle 46 more stable and controllable. When the screw thread needle 46 encounters resistance or needs to adjust its position, the elasticity of the buffer spring 4431 can provide a flexible support and adjustment space, thereby reducing the vibration and instability factors caused by sudden stop or reverse movement.

[0109] The frame is provided with a bottom plate movable slide rail 421 at the bottom of the bottom plate 41, and the length direction of the bottom plate movable slide rail 421 is the front-to-back direction. The bottom of the bottom plate 41 is provided with a first bottom plate movable slider 422, and the first bottom plate movable slider 422 is slidably connected to the bottom plate movable slide rail 421. The movable end of the bottom plate movable module 42 is fixedly connected to the bottom of the bottom plate 41, and the bottom plate movable module 42 is used to drive the first bottom plate movable slider 422 to move on the bottom plate movable slide rail 421.

[0110] Since the rotating sleeve 4331 is rotatably installed on the base plate 41, the base plate movable module 42 can not only adjust the front and rear positions of the base plate 41, but also adjust the front and rear positions of the rotating sleeve 4331 and the three-claw tool 45, so that the three-claw tool 45 can be close to the surface of the gold bead, ensuring that the three-claw tool 45 can drill the gold bead.

[0111] In addition, through the cooperation between the first bottom plate movable slider 422 and the bottom plate movable slide rail 421, the movable range of the bottom plate 41 can be accurately controlled to prevent the three-claw tool 45 from shaking during the forward movement.

[0112] The bottom plate movable module 42 includes a bottom plate movable screw rod 423, a second bottom plate movable slider 424, a bottom plate movable driving member 425, a first bottom plate movable gear 426, a second bottom plate movable gear 427 and a bottom plate movable chain;

[0113] The bottom plate movable screw rod 423 is transmission-mounted on the frame, the length direction of the bottom plate movable screw rod 423 is consistent with the length direction of the bottom plate movable slide rail 421, the bottom plate movable screw rod 423 is threadedly connected with a second bottom plate movable slide block 424, and the second bottom plate movable slide block 424 is fixedly connected to the bottom of the bottom plate 41;

[0114] The bottom plate movable driving member 425 is installed on the frame, and the output end of the bottom plate movable driving member 425 is fixedly connected to the first bottom plate movable gear 426, and the end of the bottom plate movable screw rod 423 close to the first bottom plate movable gear 426 is fixedly sleeved with the second bottom plate movable gear 427, and the bottom plate movable chain is sleeved on the first bottom plate movable gear 426 and the second bottom plate movable gear 427.

[0115] It is worth noting that the bottom plate movable driving member 425 is preferably a motor. When the bottom plate movable driving member 425 is started, it can drive the first bottom plate movable gear 426 to rotate, and the rotation of the first bottom plate movable gear 426 can drive the second bottom plate movable gear 427 and the bottom plate movable chain to rotate, and the second bottom plate movable gear 427 can drive the bottom plate movable screw rod 423 to rotate. The rotation of the bottom plate movable screw rod 423 can drive the second bottom plate movable slider 424 to move back and forth on the bottom plate movable screw rod 423, thereby driving the bottom plate 41 to move in the front-back direction.

[0116] Moreover, the screw drive has a self-locking characteristic, which can effectively prevent the base plate 41 from accidentally moving when not acted upon by external forces, thereby improving the safety and reliability of the entire system.
