Description

Technical Field

[0001] This invention relates to the field of jewelry processing technology, and in particular to a feeding device for a non-standard diamond wax setting machine. Background Technology

[0002] Diamond is a mineral composed of carbon, an allotrope of graphite. Its uses are extremely wide-ranging, including in handicrafts and industrial cutting tools. A high-quality diamond requires a sophisticated wax setting technique to truly shine. A good wax setting helps to showcase the diamond's texture and highlight the most dazzling and captivating aspect of the jewelry. Currently, diamond wax setting typically involves manually selecting and setting randomly arranged diamonds onto a wax mold. The initial feeding stage requires placing the scattered diamonds at specific stations, one by one, into specific small holes before using a transfer device for processing. Existing feeding methods generally rely on robotic arms for gripping and placing the diamonds. However, due to the small size of diamonds, this requires extremely high precision from the robotic arms, resulting in low efficiency. Manual labor, on the other hand, requires specialized tools and is also inefficient. Therefore, there is an urgent need for a highly efficient, stable, and automated machine to perform this function. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a feeding device for a special-shaped diamond wax setting machine with high feeding efficiency, stable feeding, and high degree of automation.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is: A feeding device for a non-standard diamond wax setting machine includes: a servo motor, a coupling, and a clutch. A splined shaft is provided in the middle of the clutch. The coupling connects the servo motor and the splined shaft. A hopper device is provided at the top of the clutch. The hopper device is connected to the splined shaft. A clamping device is provided on the outer ring of the hopper device. A miniature air rod is provided on the clamping device. The clamping device is connected to the clutch by a spring.

[0005] Furthermore, the clamping device has a circular arc surface in the middle, and the inner ring of the circular arc surface is connected to the hopper device.

[0006] Furthermore, when the clamping device is released upwards, the inner ring of the circular arc surface is higher than the hopper device; when the clamping device is pressed downwards, the inner ring of the circular arc surface and the hopper device are on the same plane.

[0007] Furthermore, the bottom end of the clamping device is provided with a connecting seat, the connecting seat is provided with a connecting hole in the middle, the spline shaft passes through the connecting hole to connect to the hopper device, and a helical spring is provided on the outside of the connecting hole.

[0008] Furthermore, the outer ring of the hopper is provided with several diamond grooves.

[0009] Furthermore, the clamping device is provided with two orienting devices, each orienting device including an orienting shaft.

[0010] Furthermore, the clutch is a multi-plate clutch, which includes a housing, several pressure plates and several friction plates. The pressure plates are provided with spline grooves that mate with a spline shaft, and the pressure plates are connected to springs.

[0011] Furthermore, a feeding device is provided outside the hopper device and the pressing device, and the feeding device is provided with a feeding port.

[0012] Furthermore, a positioning rod is provided on the splined shaft, and a position sensor is provided on the side of the positioning rod.

[0013] Furthermore, the position sensor is provided with a positioning groove.

[0014] The beneficial effects of this invention are: 1. This invention uses a miniature pneumatic rod to control the pressing device to press down, so that the inner ring of the circular arc surface of the pressing device is on the same plane as the hopper device. At the same time, this application incorporates the principle of clutch disengagement and closure connection. The pressing device presses down and drives the spring to press the pressure plate, realizing the clutch closure. The power of the servo motor is transmitted to the clutch through the coupling and then to the hopper device. Utilizing the high-speed forward and reverse rotation of the servo motor, the diamonds on the hopper device are automatically rolled into the diamond slots around the perimeter by centrifugal force, realizing automatic feeding. The centrifugal force is used to complete the feeding of multiple diamond slots at one time, resulting in high feeding efficiency and a high degree of automation. 2. After feeding is completed, the present invention requires continuous rotation to achieve positioning and material transfer of the transfer device. However, the centrifugal feeding and rotational angle adjustment transfer of this application are both completed by the same servo motor, which is simple in structure and easy to use. When it is necessary to adjust the centrifugal feeding to the rotational angle adjustment transfer stage, the clamping device is raised by controlling the micro air rod to disengage the clutch. The servo motor rotates in a directional low-speed delayed manner to achieve rotational angle adjustment transfer. Since the clutch disconnects the connection between the hopper device and the spline shaft during the servo motor switching process, and reconnects after the motor adjustment is completed, the diamonds on the hopper device can stably adapt to the transition between the two stages. The diamonds will not fall or fall out of the diamond slot due to the switching of the servo motor, and the feeding is stable. Attached Figure Description

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] To address the problems of low feeding efficiency, unstable feeding, and low automation in existing diamond wax setting machines, this application discloses a feeding device 13 for an irregularly shaped diamond wax setting machine, such as... Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, it includes: The device comprises a servo motor 1, a coupling 2, and a clutch 3. The clutch 3 has a splined shaft 4 in the middle. The coupling 2 connects the servo motor 1 and the splined shaft 4. Specifically, the output shaft of the servo motor 1 is connected to the coupling 2, which in turn connects to the splined shaft 4. The coupling 2 connects the output shaft of the servo motor 1 and the splined shaft 4, enabling both to rotate together during motion and power transmission. A hopper device 5 is located at the top of the clutch 3 and is connected to the splined shaft 4. Preferably, the outer ring of the hopper has several diamond slots 51. The purpose of feeding the diamond wax setting machine in this application is to arrange diamonds of different sizes into the diamond slots 51 according to a specified size. The hopper device 5 itself has a disc structure, with its central shaft sharing the same shaft as the splined shaft 4. Rotation of the splined shaft 4 enables the hopper device 5 to rotate. The outer ring of the hopper device 5 is equipped with a clamping device 6, which has a miniature air spring 61. The clamping device 6 has two functions: first, to ensure that the hopper device 5 and the clamping device 6 are on the same plane, facilitating the diamond's journey to the diamond groove 51 through centrifugal force; second, to perform the clamping function, thus disengaging the clutch 3. Preferably, the clamping device 6 has a circular arc surface 62 in the middle, and the inner ring 63 of the circular arc surface 62 is connected to the hopper device 5. Diamonds will roll onto the hopper device 5 using the circular arc surface 62. The diameter of the corresponding disc structure of the hopper device 5 is the same as the size of the inner ring 63 of the circular arc surface 62, allowing them to be tangent to each other. Preferably, when the clamping device 6 is released upwards, the inner ring 63 of the circular arc surface 62 is higher than the hopper device 5; when the clamping device 6 is pressed downwards, the inner ring 63 of the circular arc surface 62 is on the same plane as the hopper device 5. In the initial state of this application, the inner ring 63 of the annular arc surface 62 is higher than the material storage device 5. When feeding is required, the diamond is poured into the material storage device 5. The micro air rod 61 moves downward to drive the pressing device 6 downward, so that the inner ring 63 of the annular arc surface 62 and the material storage device 5 are on the same plane. At this time, the diamond can be moved to the diamond groove 51 by rotating the material storage device 5 and using centrifugal force.

[0018] Preferably, the clamping device 6 and the clutch 3 are connected by a spring. Specifically, the connection structure is as follows: a connecting seat 64 is provided at the bottom of the clamping device 6, a connecting hole 65 is provided in the middle of the connecting seat 64, the splined shaft 4 passes through the connecting hole 65 to connect to the hopper device 5, and a helical spring 66 is provided on the outside of the connecting hole 65. Preferably, as... Figure 4 , Figure 5As shown, the clutch 3 is a multi-plate clutch 3, which includes a housing 31, several pressure plates 32, and several friction plates 33. The pressure plates 32 are provided with spline grooves 34 that mate with the spline shaft 4. The pressure plates 32 are connected by springs, specifically helical springs 66. When the miniature air rod 61 moves downward to drive the pressing device 6 downward, the pressing device 6 drives the spring to press the pressure plates 32 downward, thus engaging the friction plates 33. In the clutch 3 configuration, the pressure plates 32 are typically placed on top, and the friction plates 33 are placed below. This arrangement involves alternating layers of pressure plates 32 and friction plates 33. When the pressure plates 32 are pressed downward by the spring force, they engage with the friction plates 33. At this time, the spline shaft 4, in conjunction with the spline grooves 34 on the pressure plates 32, can transmit power to the upper hopper device 5. Because the friction plates 33 themselves have high friction, the clutch 3 achieves engagement through this contact friction, thereby transmitting power.

[0019] Preferably, the clamping device 6 is provided with two orienting devices 7, each orienting device 7 including an orienting shaft 71. The orienting device 7 ensures that the miniature pneumatic rod 61 moves vertically in the up-down direction, preventing deviation.

[0020] Preferably, a feeding device 8 is provided outside the hopper device 5 and the pressing device 6, and the feeding device 8 is provided with a feeding port 81.

[0021] Preferably, a positioning rod 41 is provided on the splined shaft 4, and a position sensor 9 is provided on the side of the positioning rod 41. Preferably, the position sensor 9 is provided with a positioning groove 91. The position sensor 9 is used in the second step of rotating and adjusting the angle of material transfer. The position sensor 9 can determine whether the entire hopper device 5 has completed one revolution through the positioning rod 41 and the positioning groove 91. When one revolution is completed, it means that there are no diamonds in the diamond groove 51 of the hopper device 5, and the next feeding is performed, and so on. The feeding is accurate and the structure is stable.

[0022] The specific method of using this application is as follows: like Figure 7As shown, the feeding device 13 corresponding to this application is located on the right side of the entire fancy diamond wax setting machine. The transfer device 14 is located in the middle of the fancy diamond wax setting machine, and the diamonds are initially placed in the material tray 16 of the machine. To the left of the transfer device 14 is the setting device 15. The function of the entire fancy diamond wax setting machine is to move the diamonds from the feeding device 13 to the setting device 15 on the left side via the transfer device 14 for setting. The feeding device 13 of this application has two main functions: centrifugal feeding of the scattered diamonds to the designated diamond slot 51 and rotation adjustment to position and move the diamonds using the transfer device 14. This is divided into two stages: a centrifugal feeding stage and a rotation adjustment stage. First, the operator pours the diamonds from the material tray 16 of the irregular diamond wax setting machine into the inlet 81 of the feeding device 8. The diamonds roll down through the annular arc surface 62 of the pressing device 6 into the hopper device 5, starting the first stage of centrifugal feeding. The pressing device 6 is driven downward by the downward movement of the micro air rod 61, so that the inner ring 63 of the annular arc surface 62 is on the same plane as the hopper device 5. The pressing device 6 drives the spring to press the pressure plate 32 downward. The pressure plate 32 engages with the friction plate 33. When the pressure plate 32 is pressed downward by the force of the spring, the pressure plate 32 engages with the friction plate 33. At this time, the spline shaft 4 and the spline groove 34 set on the pressure plate 32 can transmit power to the hopper device 5 above. Since the friction plate 33 itself has a large friction force, the clutch 3 is engaged by the friction force after contact, thereby transmitting power. Initially, the servo motor 1 rotates at high speed in both the forward and reverse directions in a sequential cycle, using centrifugal force to drop the diamonds from the hopper device 5 into the diamond grooves 51. When all the diamond grooves 51 are filled with diamonds, the first stage is completed, and the rotation angle adjustment stage begins. First, the micro air spring 61 moves upward to drive the clamping device 6 upward, causing the pressure plate 32 to disengage from the friction plate 33, thus disengaging the clutch 3 and stopping power transmission to the upper hopper device 5. Then, the servo motor 1 is adjusted to rotate at a specified angle, and the micro air spring 61 moves downward again to drive the clamping device 6 downward. Then, the material transfer device 14 comes to pick up and transfer the material. The position of the material transfer device 14 is determined. Therefore, the diamonds on the diamond grooves 51 can be moved and processed sequentially by the material transfer device 14 through the continuous rotation of the hopper device 5. The position sensor 9 is equipped with a positioning groove 91, which will sense the position rod 41 on the spline shaft 4 passing by. When it passes by for the second time, it means that the entire hopper device 5 has rotated once, completing the transfer of all diamond grooves 51. Then, the centrifugal feeding stage above is repeated, and the cycle is repeated to complete the feeding.

[0023] This invention combines the principle of clutch disengagement and closure. The pressing device presses down to drive the spring to press the pressure plate, thereby closing the clutch and achieving automatic feeding with high feeding efficiency and a high degree of automation. The clutch enables the switching between the two stages of centrifugal feeding and rotational angle adjustment for material transfer. The diamond will not fall or fall out of the diamond slot due to the switching of the servo motor, resulting in stable feeding and a high degree of automation.

[0024] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any changes or modifications made in accordance with the claims and specification of the present invention should fall within the scope of the patent of the present invention.
