In traditional manual sorting, human eyes are prone to make mistakes when identifying, resulting in errors in the value assessment of the processed jewelry. In view of this, a color selection pearl core machine and a selection method are proposed. Summary of the invention

[0005] Furthermore, the photosensitive spring is made of a mixture of photosensitive material and memory alloy material, and the material channel plate is inclined.

[0006] Furthermore, an anti-falling ring is provided on the outside of the material discharge tray to prevent the bead nucleus from falling out, and a material pipe extension piece is provided below the material receiving pipe, and one end of the material discharge tray is inserted into the material pipe extension piece.

[0010] Furthermore, the slot is in a right-angle trapezoidal shape, and the other side of the insert tube is plugged into the slot.

[0011] A color selection bead core selection method, providing a color selection bead core machine as claimed in any one of claims 1 to 8, the color selection bead core machine, the color selection bead core selection method comprising the following steps: S1: The hopper is connected to the material pipe, one end of the feed tray is plugged into the material pipe extension piece of the material pipe, and then the color-selected beads are added into the hopper, and the beads fall into the trough on the feed tray, and then the trough starts to rotate with the gravity of the beads; S2: Turn on the infrared irradiator switch and energize it for irradiation. The bead nucleus rotates in the material trough on the unloading tray until the unloading tray rotates to the bottom and slides into the inclined material channel plate. The bead nucleus rolls downward, rolls onto the infrared irradiator, and rolls down with the material channel plate. When the bead nucleus has mixed colors, the mixed-color bead nucleus will absorb the light irradiated by the infrared irradiator, and the photosensitive spring that has not received the light will return to its original state, so that the mixed-color bead nucleus slides out from the side slide plate. On the contrary, the pure-color bead nucleus will allow the light of the infrared irradiator to penetrate and irradiate the photosensitive spring, causing the photosensitive spring to shrink into the side installation cylinder. After shrinkage, the pure-color bead nucleus enters the lower opening of the material channel plate, thereby improving the inspection accuracy of the bead nucleus; S3: The insert is inserted into the slot of the mounting seat, and the top rod of the extension plate pushes up one side of the insert. The support rod outside the convex tube of the extension plate fits with the insert through a spring. The solid-color bead nucleus enters the bottom of the material channel plate and then slides out of the material channel plate and enters the outer tube of the insert. Bags for bead nuclei are set at a distance below the outer tube. The spherical bead nuclei roll between the two outer tubes. The heavier the bead nucleus, the more the head ends of the two inserts move inward in the right-angled trapezoidal slots. At the same time, the support rod is pushed up, so that the two inserts change from a parallel state to an outward expansion state according to the weight of the bead nuclei, until the bead nuclei fall at different distances on the insert, so as to achieve the classification of bead nuclei of different sizes. Beneficial Effects

[0012] After the bead nucleus is placed in the hopper, the bead nucleus enters the discharge tray along with the material tube. Since one end of the discharge tray is embedded in the extension piece of the material tube, the discharge tray begins to rotate with gravity after the bead nucleus enters the discharge tray, and the material is separated in sequence. Then the bead nucleus enters the inclined material channel plate. Since the light irradiated by the infrared illuminator has temperature when it reaches the target, the colorful bead nucleus will absorb the light irradiated by the infrared illuminator, and the photosensitive spring that has not received the light will return to its original state, so that the colorful bead nucleus will slide out from the side slide plate. Conversely, the pure color bead nucleus will allow the light to penetrate and shine on the photosensitive spring, causing the photosensitive spring to shrink, thereby causing the photosensitive spring extension plate to shrink along the material channel plate, and the pure color bead nucleus will enter the lower opening of the material channel plate, thereby improving the inspection accuracy of the bead nucleus.

[0013] 2. The top rod of the extension plate pushes up one side of the insert tube to provide support for the insert tube. The support rod outside the convex tube of the extension plate fits with the insert tube through a spring. The pure-color bead nucleus enters the bottom of the material channel plate and then slides out of the material channel plate and enters the outer tube of the insert tube. Bags for bead nuclei are set at a distance below the outer tube. The spherical bead nucleus rolls between the two outer tubes. The heavier the bead nucleus, the more the head ends of the two insert tubes move inward in the right-angled trapezoidal slots. At the same time, the support rod is pushed up, so that the two insert tubes change from parallel to outward expansion according to the weight of different bead nuclei, until the bead nucleus falls at different distances on the insert tube, so as to achieve the classification of bead nuclei of different sizes and further improve the practicality of the device.

DETAILED DESCRIPTION

[0024] Please refer to Figures 1 to 8 ; The present embodiment provides a color selection bead core machine, including a mounting seat 1, a hopper 101 is arranged on one side of the mounting seat 1, the output end of the hopper 101 is connected to a material pipe 102, a material discharge tray 2 is arranged on one side of the material pipe 102, and an inclined material channel plate 3 is arranged on one side of the material discharge tray 2, characterized in that: an infrared irradiator 4 is arranged on one side of the material channel plate 3, a parallel side slide plate 5 is arranged on one side of the material channel plate 3, a side mounting cylinder 501 is arranged on one side of the side slide plate 5, and a photosensitive spring 6 that reacts to the light source emitted by the infrared irradiator 4 is arranged in the side mounting cylinder 501; refer to Figures 1 to 4 , the light irradiated by the infrared illuminator 4 is monochromatic, and the installation direction of the infrared illuminator 4 is parallel to the material channel plate 3 below, and the photosensitive spring 6 and the infrared illuminator 4 are on the same horizontal line, and a material trough 201 arranged in a ring array is arranged on the outside of the unloading tray 2. According to the color selection bead core machine described in claim 2, it is characterized in that: the photosensitive spring 6 is made of a mixture of photosensitive material and memory alloy material, the material channel plate 3 is inclined, and the outside of the unloading tray 2 is also provided with an anti-slip ring 103 to prevent the bead core from falling out, and a material pipe extension piece 102-1 is also provided under the material connecting pipe 102, and one end of the unloading tray 2 is plugged into the material pipe extension piece 102-1, and a triangular bottom plate 104 is also provided at the bottom of the mounting seat 1, and four support columns 105 are provided at the bottom of the bottom plate 104; In a specific embodiment, the hopper 101 is connected to the material tube 102, and one end of the discharge tray 2 is plugged into the material tube extension piece 102-1 of the material tube 102. Then, the color-selected bead nuclei are added into the hopper 101, and the bead nuclei fall onto the material trough 201 on the discharge tray 2. Then, the material trough 201 starts to rotate with the gravity of the bead nuclei, so that the single bead nuclei are selected in sequence. The infrared irradiator 4 is turned on for irradiation, and the bead nuclei rotate in the material trough 201 on the discharge tray 2 until the discharge tray 2 rotates to the bottom and slides into the inclined material channel plate 3. The bead nuclei roll downward, roll onto the infrared irradiator 4, and follow the material channel. Plate 3 rolls down. When the bead nucleus contains mixed colors, the mixed-color bead nucleus will absorb the light irradiated by the infrared illuminator 4, and the photosensitive spring 6 that has not received the light will return to its original state, thereby causing the mixed-color bead nucleus to slide out from the side slide plate 5. On the contrary, the pure-color bead nucleus will allow the light of the infrared illuminator 4 to penetrate and irradiate the photosensitive spring 6, causing the photosensitive spring 6 to shrink into the side mounting tube 501.

Since the feed tray 2 rotates in the through hole of the material tube extension piece 102-1, there is friction, and the arc reduces the rotation speed of the feed tray 2, so that the photosensitive spring 6 has more time to reset and contract.

[0026] Preferably, reference Figures 1 to 8 , one side of the mounting seat 1 is also provided with two protruding extension plates 106, and two symmetrically arranged slots 107 are also arranged between the two extension plates 106 of the mounting seat 1, and the insert tube 7 is inserted in the slot 107, and an extension plate convex cylinder 106-1 is arranged on one side of the extension plate 106, and a spring 106-2 is arranged in the extension plate convex cylinder 106-1, and one end of the spring 106-2 is connected to a support rod 8 with the same inner diameter as the extension plate convex cylinder 106-1, and the support rod 8 is in contact with the insert tube 7, and an external cylinder 701 is also arranged in the middle of the insert tube 7, and a push rod 106-3 that pushes up one end of the insert tube 7 is also arranged on one side of the extension plate convex cylinder 106-1, and the slot 107 is in a right-angle trapezoid, and the other side of the insert tube 7 is plugged into the slot 107; In another specific embodiment, the insert tube 7 is inserted into the slot 107 of the mounting seat 1, and the top rod 106-3 of the extension plate 106 pushes up one side of the insert tube 7, and the support rod 8 outside the extension plate convex tube 106-1 is fitted with the insert tube 7 through the spring 106-2. The solid color bead nucleus enters the bottom of the material channel plate 4 and then slides out of the material channel plate 4 and enters the outer tube 701 of the insert tube 7. Bags for bead nuclei are arranged at a distance below the outer tube 701, and the spherical bead nuclei roll between the two outer tubes 701. The heavier the bead nucleus, the more the head ends of the two insert tubes 7 move inward in the right-angled trapezoidal slot 107, and at the same time, the support rod 8 is pushed up, so that the two insert tubes 7 change from a parallel state to an outwardly expanded state according to the weight of the different bead nuclei, until the bead nucleus falls at different distances on the insert tube 7, so as to achieve the classification of bead nuclei of different sizes, thereby further improving the practicality of the device.
