[0002] Diamonds refer to polished diamond, and diamond is a natural mineral and the raw material of diamonds; diamond production is scarce, usually colorless crystals, and in addition to the characteristic of high material hardness, it also has a high refractive property, which can refract colorful luster; so diamonds can not only be used as high-grade cutting and grinding materials in industry, but also be used as selected materials for optics, semiconductors, and jewelry; its uses are very extensive. For jewelry, a high-quality diamond must be combined with excellent wax setting technology to complement each other. Good wax setting is more helpful to show the texture of the diamond and show the most dazzling and moving side of the diamond jewelry;

[0003] In the early days, people screened and picked out disordered diamonds one by one, and basically used a manual operation mode to inlay the diamonds on the wax mold; at present, although there have been improvements, the method of using a manipulator to pick up diamonds and paste and inlay diamonds has improved the original pure manual inlaying method; however, before the manipulator picks up diamonds, the feeding is still manual. Workers sprinkle disordered diamonds on a specific diamond template (there are specific small holes on the template), and evenly brush the diamonds with a brush, and manually rub the diamonds back and forth to prompt the diamonds to fall into the holes in an orderly manner according to the direction of the specific small holes; then manually put the diamond template filled with diamonds into the equipment, and then the manipulator of the equipment picks up diamonds on the diamond template and pastes and inlays them on the wax mold; because the diamonds are small, the accuracy requirements for the manipulator are too high, and there is a certain deviation in the position of manually placing the diamond template each time, resulting in unstable material picking by the manipulator; moreover, the method of brushing and rubbing diamonds manually has low efficiency; therefore, there is an urgent need to develop a device with high feeding efficiency, stable feeding, and high automation to achieve this function;

[0021] Embodiment

[0022] Please refer to Figures 1-6 , the present utility model provides a technical solution: a diamond rotary automatic feeding device;

[0023] In the existing diamond feeding, diamond brushing and rubbing, and diamond pasting and inlaying operations are all carried out by personnel, resulting in low overall operation efficiency;

[0024] Based on the above problems, the components in this case include a component mounting plate 1, a panel 2 is connected to the top of the component mounting plate 1, motor mounting columns 3 are installed on both sides of the bottom of the component mounting plate 1, a motor mounting plate 4 is connected to the bottom of the motor mounting column 3, a row of feeding stations are horizontally distributed on the top of the panel 2, and a rotating component and a storage component are provided at each feeding station;

[0025] The rotating component includes a stepper motor 5, a rotary joint 6 is connected to the shaft end of the stepper motor 5, a clamping hoop and an inductive sheet 7 are installed at the lower part of the rotary joint 6, a bearing 8 is installed at the axial step in the middle of the rotary joint 6, a positioning pin 9 and a rotating disk 10 are installed at the top of the rotary joint 6, and diamond placement grooves are evenly distributed on the circumference of the top of the rotating disk 10;

[0026] The material storage assembly includes a cylinder fixing plate 11, which is fixed to the bottom of the motor mounting plate 4. A cylinder 12 is installed on the cylinder fixing plate 11. Above the motor mounting plate 4, a motor positioning plate 13 and a photoelectric sensor 14 are installed. At the top of the output end of the cylinder 12, a floating joint 15 is provided. A linear guide rail slider 16 is connected to a slider fixing plate 17. The floating joint 15 is connected to the linear guide rail slider 16, and the linear guide rail slider 16 is connected to the slider fixing plate 17. Above the feeding station, a material storage hopper 18 is provided, and the linear guide rail slider 16 is locked on the side wall of the material storage hopper 18;

[0027] On the top of the motor mounting plate 4, a spacer base 19 is provided. A spacer 20 is installed on the spacer base 19. There is a clearance between the material storage hopper 18 and the spacer 20. On the outside of the driving end of the cylinder 12, an upper limit detection switch 21 and a lower limit detection switch 22 are respectively provided. The inside of the material storage hopper 18 is U-shaped;

[0028] In this technical solution, four stepping motors 5 respectively correspond to the rotating disks 10 of the four feeding stations, and separately drive them to perform forward and reverse rotation actions. Four cylinders 12 respectively correspond to the material storage hoppers 18 of the four feeding stations, and separately push and pull the corresponding linear guide rail sliders 16 and the material storage hoppers 18 to move vertically. Each cylinder 12 is equipped with an upper limit detection switch 21 and a lower limit detection switch 22, which are used to detect the upper and lower limit positions of the cylinder 12 and output signals;

[0029] The motor mounting plate 4 together with the 4 separate feeding stations is integrally installed on the two motor mounting columns 3 on both sides. The two motor mounting columns 3 on both sides are installed in an inverted manner on the component mounting plate 1. The component mounting plate 1 together with the whole set of mechanisms is installed on the equipment, which can achieve the free disassembly of the whole set of devices, facilitating debugging and maintenance. The stepping motor 5 rotates, continuously driving the rotating disk 10 at the top of the device to perform left and right rotation actions. The head of the push rod of the cylinder 12 is equipped with a floating joint 15, which is used to push and pull the upper linear guide rail slider 16 and the material storage hopper 18 to perform vertical linear motion. The spacer 20 plays a guiding role when the material storage hopper 18 moves up and down. Among them, the whole material storage hopper 18 is made of a flexible material. When the cylinder 12 operates, it can push the outer edge of the material storage hopper 18 and lift the outside of the material storage hopper 18;

[0030] As Figure 3 、 6 shown, when the device operates, the stepping motor 5 rotates, driving the induction piece 7 to trigger with the photoelectric sensor 14, and controlling the stepping motor 5 to drive the rotating disk 10 to be positioned at the reference position (i.e., the position where the manipulator defaults to pick up materials). The stepping motor 5 is equipped with a home zero photoelectric sensor 14, which is used to control the stepping motor 5 to return to zero at the same position reference point. After returning to zero, pulses are sent according to needs to control the forward and reverse positions of the stepping motor 5. And in this technical solution, the feeding stations are divided into feeding stations 1-4 from left to right;

[0031] Drill Brushing and Preparation Action

[0032] As Figures 1-6 shown, when the manipulator performs the operation of picking up and pasting drills at the loading stations 3 and 4, the loading stations 1 and 2 perform the drill brushing and preparation operation. The entire drill brushing and preparation action is as follows:

[0033] Action 1: The cylinder 12 operates, driving the linear guide rail slider 16 and the U-shaped storage hopper 18 filled with diamonds to lift, raising the outer edge of the storage hopper 18, and causing the diamonds to slide into the outside of the rotating disk 10 in a free-fall manner. Among them, the inner edge of the storage hopper 18 is close to the outer edge of the rotating disk 10;

[0034] Action 2: After the cylinder 12 is lifted, the upper limit detection switch 21 detects the signal and controls the stepping motor 5 to rotate forward and backward three times each. The purpose is to make the diamonds flip in the rotating disk 10 like a sieve. According to the consistency between the shape of the diamonds and the die hole shape on the surface of the rotating disk 10, the diamonds that flip several times will automatically find the correct angle and fall tightly into the die holes;

[0035] Action 3: The cylinder 12 drives the linear guide rail slider 16 and the outer edge of the storage hopper 18 to pull down. The middle part of the rotating disk 10 is set as a protrusion. After the outer edge of the storage hopper 18 is pulled down, affected by gravity, the remaining diamonds will fall back into the U-shaped groove of the storage hopper 18;

[0036] Action 4: After the cylinder 12 is pulled down, the lower limit detection switch 22 detects the signal, and the stepping motor 5 starts to rotate slowly forward and backward one circle each. At this time, the loose diamonds will be affected by the centrifugal force and move outward, and enter the U-shaped groove of the hopper that has been reset after being pulled down. At this time, the entire drill brushing and preparation operation of the loading stations 1 and 2 is completed;

[0037] When the drill brushing and preparation operation of the loading stations 1 and 2 is completed, at the same time, after the manipulator that coordinates with the device completes one circle of picking up and pasting drills at the loading stations 3 and 4, the manipulator is switched to the loading stations 1 and 2 where the drill brushing and preparation has been completed, and then the picking up and pasting drill action is performed. At this time, the loading stations 3 and 4 perform the drill brushing and preparation operation, and so on, with cyclic alternating actions.

[0038] Picking up and Pasting Drill Action

[0039] As Figure 2 、 3 、5, 6 shown, when the loading stations 1 and 2 are performing drill brushing and preparation, at this time the manipulator is picking up and pasting drills at the loading stations 3 and 4. The entire picking up and pasting drill action is as follows:

[0040] Action 1: Through an electric control instruction, move the position of the suction drill bit in the robotic arm to the reference position of the turntable 10 at the feeding stations 3 and 4 to pick up drills. There are 98 die holes evenly distributed on the circumference of the turntable 10, which can accommodate 98 diamonds. Each time the suction drill bit picks up 2 diamonds (2 suction nozzles, with a position interval of 13 diamonds between the suction nozzles), and it takes 49 cycles to pick up all the diamonds;

[0041] Action 2: While the suction drill bit picks up a drill for diamond pasting once, the corresponding stepper motor 5 at the feeding station drives the turntable 10 to rotate and move the position of one diamond;

[0042] Action 3: While the suction nozzle picks up the 14th batch of materials for diamond pasting, at this time, the corresponding stepper motor 5 at the feeding station drives the turntable 10 to rotate and move the position of 14 diamonds to pick up drills;

[0043] Action 4: Sequentially cycle Action 2 to pick up and paste diamonds;

[0044] In summary, sequentially cycle Action 2 and Action 3, with 7 back-and-forth cycles in one period to complete the operation of picking up and pasting 98 diamonds on the entire circumference of the turntable 10. After completion, the feeding stations 3 and 4 start to brush and prepare drills in a cycle, and at the same time, the robotic arm enters the feeding stations 1 and 2 to pick up and paste diamonds;

[0045] The above actions alternate between the feeding stations 1, 2 and the feeding stations 3, 4, and sequentially cycle the actions, so as to realize highly automated diamond automatic feeding. Compared with the existing manual operation, it has the advantages of high feeding efficiency, stable feeding, and high automation degree.

[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
