Description

Technical Field

[0001] This utility model relates to the field of sorting and testing equipment, specifically to an intelligent pearl testing device for automatic sorting. Background Technology

[0002] Pearls are an ancient organic gemstone, mainly produced in the bodies of pearl oysters and other mollusks. They are calcium carbonate mineral (aragonite) beads formed by the endocrine processes of pearl oysters and other mollusks. Pearls are composed of a large number of tiny aragonite crystals and have a beautiful color and elegant temperament. They symbolize health, purity, wealth and happiness and have been loved by people since ancient times. They are usually required to be basically the same size for better beauty.

[0003] Because pearls vary greatly in size, their value differs significantly. Therefore, before processing, pearls need to be sorted by size and quality. To address this issue, the existing Zhongrui Microvision pearl sorting machine includes a feed inlet with a spiral disc at its bottom. A motor is fixedly connected to the bottom of the spiral disc, and the motor signal is connected to a central controller. A channel is connected to the outer wall of the spiral disc, and a lever is fixedly connected to the side of the spiral disc near the channel. A detection mechanism is located at the other end of the channel, and the output of the detection mechanism is connected to the input of the central controller. The output of the controller is connected to a sorting mechanism. Through the cooperation of the spiral disc and the lever, the pearls are transported in a single line to the detection and sorting mechanisms for detection and sorting.

[0004] In actual implementation, although the pearls are transported in a single line to the testing and sorting mechanisms via a spiral disc and a lever, during the pearl transport process, the rotation of the spiral disc base drives the pearls piled at the bottom to rotate, thereby generating a pushing force on the pearls at the top to transport them to the channel. However, when there are few pearls left in the spiral disc and only pearls remain at the bottom, the rotation of the bottom pearls cannot generate a pushing force on the remaining pearls, thus failing to transport the remaining pearls to the channel. Consequently, not all the pearls input can be sorted in the testing box.

[0005] Therefore, this utility model proposes an intelligent pearl detection device for automatic sorting to solve the above problems. Utility Model Content

[0006] To address the aforementioned issues, this invention provides an intelligent pearl sorting and detection device. By using a spiral track and a conveyor channel, the accumulated pearls are arranged in a single row to facilitate screening and detection. When a small number of pearls remain in the chassis, the remaining pearls are transported in a single row to the conveyor channel using an auxiliary track and a first air pump, thereby screening and detecting all pearls fed into the hopper.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows: An intelligent pearl sorting device includes a housing, a feeding hopper fixedly connected to the side wall of the housing, a first air pump connected to the bottom of the feeding hopper, a controller connected to the input end of the first air pump, a chassis at the bottom of the feeding hopper, the chassis and the feeding hopper being located in the same vertical direction and not in contact, a spiral track fixedly connected to the outer wall of the chassis along its circumference, pressure sensors being provided on both the spiral track and the chassis, a conveying channel connected to the outer end of the spiral track, the conveying channel being connected to the side wall of the housing, an auxiliary track connected to the bottom of the spiral track, the auxiliary track extending outside the spiral track and connected to the conveying channel, a driving component providing driving force to the chassis being provided at the bottom of the chassis, and a triangular lever fixedly connected to the side of the spiral track near the transmission channel.

[0008] The technical principle of the above solution is as follows: The weight of the chassis and the spiral track is identified by a pressure sensor, and then the pressure signal is transmitted to the controller. The controller controls the drive component to rotate, thereby rotating the chassis and causing the bottom pearls to rotate. The rotation of the bottom pearls applies a thrust to the top pearls, pushing them onto the spiral track and then into the conveyor channel. When the height of the pearls in the chassis is lower than the bottom of the spiral track, the controller controls the first and second air pumps to generate positive pressure. The first air pump blows the pearls in the chassis into the auxiliary track, and then the second air pump transports the pearls to the conveyor channel. The pearls are arranged into a single row for transport by a triangular block.

[0009] The above solution has the following advantages: Compared with the existing technology, this solution uses a controller to automatically control the drive components to drive the spiral track to transport pearls to the conveyor channel. When the pressure signal of the pressure sensor above the spiral track is in a pressureless state, the controller identifies the information that there are not enough pearls in the chassis through the pressure signal, and then controls the first air pump and the second air pump to transport the remaining pearls to the conveyor channel through the auxiliary track, thereby avoiding the waste caused by the bottom pearls being missed.

[0010] Furthermore, the drive assembly includes a first motor, which is fixedly connected to the side wall of the housing. The input end of the first motor is electrically connected to the output end of the controller. The output shaft of the first motor is fixedly connected to a support column, and the top of the support column is fixedly connected to the bottom of the chassis.

[0011] Beneficial effects: The controller controls the operation of the first motor, which drives the support column to rotate, thereby driving the chassis to rotate and arranging and transporting the pearls.

[0012] Furthermore, a pearl ring is provided at the bottom of the conveyor channel away from the spiral track. Several grooves are provided on the top of the pearl ring along its circumference. A rotating column is fixedly connected to the bottom of the pearl ring, and a second motor is fixedly connected to the bottom of the rotating column. The input end of the second motor is electrically connected to the controller.

[0013] Beneficial effects: Pearls are placed on a pearl ring through a conveyor channel, and the pearl ring is rotated by a motor, so that the pearls are placed in the grooves respectively, so that the pearls can be placed separately for subsequent accurate testing.

[0014] Furthermore, a conveyor belt is installed at the bottom of the conveyor channel.

[0015] Beneficial effect: The conveyor belt design transports pearls one by one to the pearl ring, preventing multiple pearls from falling off the pearl ring when transported to the same groove at the same time.

[0016] Furthermore, a fixed column is fixedly connected to the top wall inside the box, a fixed ring is fixedly connected to the middle of the fixed column, and an array light source is fixedly connected to the bottom of the fixed ring. The input end of the array light source is electrically connected to the output end of the controller.

[0017] Beneficial effects: The array light source design provides a bright environment for pearl sorting, facilitating accurate pearl sorting.

[0018] Furthermore, several high-pressure nozzles are fixedly connected to one side of the bottom of the fixed column, and the input end of each high-pressure nozzle is electrically connected to the output end of the controller.

[0019] Beneficial effect: The controller controls the corresponding high-pressure nozzle to accurately blow out and collect the sorted pearls.

[0020] Furthermore, several cameras are fixedly connected to the bottom of the fixed column on the side away from the high-pressure nozzle, and the output end of each camera is electrically connected to the input end of the controller.

[0021] Beneficial effects: Images of pearls are collected by a camera, and then the image information from the mobile phone is transmitted to the controller input terminal. The controller's corresponding algorithm then accurately sorts the pearls.

[0022] Furthermore, the housing has an opening on the side near the high-pressure nozzle, and several collection channels corresponding to the high-pressure nozzle are provided inside the opening. The collection channels are set in an S-shaped structure, and the top of each collection channel is fixedly connected to the side wall of the fixing ring. The top opening of the collection channel is aligned with the corresponding high-pressure nozzle.

[0023] Beneficial effects: The collection channel design allows pearls sorted according to different standards to be collected separately, facilitating processing and treatment based on their different sizes and qualities.

[0024] Furthermore, the inner walls of the collection channels are all equipped with elastic layers.

[0025] Beneficial effects: The elastic layer design prevents pearls from colliding with the inner wall of the collection channel when they are collected, thus avoiding wear and tear on the pearls and affecting their quality.

[0026] Furthermore, baffles are fixedly connected to the outer sides of both the spiral track and the auxiliary track along their circumference.

[0027] Beneficial effect: The baffle design prevents pearls from overflowing and being lost during transport along the spiral and auxiliary tracks.

[0028] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0037] The following detailed description illustrates the specific implementation methods:

[0038] Example 1:

[0039] As attached Figure 1 As shown: An intelligent pearl sorting and inspection device includes a housing 1. A feeding hopper 2 is welded to the side wall of the housing 1. Since pearl sorting requires individual inspection of the size and quality of each pearl, a base plate 5 is provided at the bottom of the feeding hopper 2 to facilitate individual sorting. The base plate 5 and the feeding hopper 2 are located in the same vertical direction and do not contact each other. A spiral track 6 is welded to the outer wall of the base plate 5 along its circumference. Pressure sensors are provided on both the spiral track 6 and the base plate 5. The outer end of the spiral track 6 is connected to a conveying channel 7. The bottom of the conveying channel 7... The unit is equipped with a conveyor belt 16, and the conveyor channel 7 is connected to the side wall of the box 1. The bottom of the chassis 5 is equipped with a drive assembly that provides rotational driving force for the chassis 5. A triangular lever 9 is welded to the side of the spiral track 6 near the conveyor channel 7. The rotation of the chassis 5 drives the bottom pearls to rotate, pushing the top pearls to the spiral track 6, and then to the conveyor channel 7. When there are too few pearls in the chassis 5 to push the pearls to the conveyor channel 7, the remaining pearls cannot enter the box 1 for sorting. In order to ensure that all pearls fed into the feed hopper 2 can be sorted, as shown in the attached... Figure 2 and attached Figure 3As shown, the bottom of the feed hopper 2 is connected to a first air pump 3, preferably a KNF NF1.5. The input terminal of the first air pump 3 is connected to a controller, preferably an NVIDIA Jetson Nano. The bottom of the spiral track 6 is connected to an auxiliary track 8, and the side of the auxiliary track 8 near the chassis 5 is connected to a second air pump 4, preferably a Thomas air pump. 7500, the input end of the second air pump 4 is connected to the output end of the controller. The auxiliary track 8 extends to the outside of the spiral track 6 and is connected to the conveying channel 7. The connection between the auxiliary track 8 and the conveying channel 7 is located between the triangular block 9 and the spiral track 6. The drive component includes the first motor 10. The preferred model of the first motor 10 is Zhaowei ZGA37RP. The first motor 10 is welded to the side wall of the housing 1. The input end of the first motor 10 is electrically connected to the output end of the controller. The output shaft of the first motor 10 is coaxially fixedly connected to the support column 11. The top of the support column 11 is welded to the bottom of the chassis 5. To prevent the pearls from falling out of the track due to compression when rolling on the spiral track 6 and the auxiliary track 8, baffles 23 are welded to the outer sides of the spiral track 6 and the auxiliary track 8 along their circumference.

[0040] The specific implementation process is as follows: Since the size and quality of pearls have a significant impact on their value, and different qualities of pearls have different processing methods and uses, pearls need to be sorted before processing to ensure their full value is realized. Sorting pearls requires individual testing. When sorting is necessary, pearls are fed into the feed hopper 2, allowing them to be placed in the base plate 5. At this point, the pearls are positioned on the base plate 5 and the spiral track 6. Pressure sensors on the spiral track 6 and the base plate 5 simultaneously transmit pressure signals to the controller, causing the controller to automatically control the operation of the first motor 10. The output shaft of the first motor 10 drives the support column. 11 rotates coaxially, and the support column 11 drives the chassis 5 to rotate. The rotation of the chassis 5 causes the pearls piled on the chassis 5 to rotate. At this time, the pearls are piled up because of the large number of pearls. The pearls at the top are pushed onto the spiral track 6 by the rotating pearls at the bottom. Then, through the continuous rotation of the pearls at the bottom and the continuous addition of pearls by the feed hopper 2, a continuous thrust is applied to the pearls on the spiral track 6, so that the pearls are transported along the spiral track 6 to the top of the spiral track 6. Then, the pearls at the top of the spiral track 6 are limited by the triangular lever 9 so that the pearls enter the conveyor channel 7 in a single row. The conveyor belt 16 transports the pearls one by one into the box 1 for inspection and sorting.

[0041] When the feed hopper 2 stops feeding, the pearls in the chassis 5 continue to be transported along the spiral track 6 and gradually decrease. The pressure on the pressure sensor on the spiral track 6 decreases. When the number of pearls in the chassis 5 decreases to a certain level, the rotation of the chassis 5 and the pearls alone cannot transport the bottom pearls to the conveying channel 7. At this time, the pressure sensor on the spiral track 6 is in a non-pressured state and transmits this pressure signal to the controller. The controller controls the first air pump 3 and the second air pump 4 to generate positive pressure according to the pressure signal. The positive pressure of the first air pump 3 blows the pearls in the chassis 5 into the auxiliary track 8. Pearls are propelled along the auxiliary track 8 to the conveying channel 7 by the positive pressure of the second air pump 4. The pearls output from the auxiliary track 8 are limited by the triangular lever, allowing them to be transported in a single row into the conveying channel 7. When the pressure sensors on the chassis 5 and the spiral track 6 are both in an unpressurized state, the controller receives a pressure signal and controls the first motor 10, the first air pump 3, and the second air pump 4 to stop operating. Through the rotation of the controller, pressure sensors, spiral track 6, auxiliary track 8, and chassis 5, all the pearls are ensured to enter the box 1 for sorting, thus preventing any pearls from being missed.

[0042] Example 2:

[0043] As attached Figure 2 As shown, the difference from Embodiment 1 is that after the pearls are transported to the box 1 in a single row, each pearl needs to be inspected individually. To facilitate accurate inspection by separating the pearls, a pearl ring 12 is provided at the bottom of the conveyor channel 7 away from the spiral track 6. Several grooves 13 are provided around the top of the pearl ring 12, and a rotating column 14 is welded to the bottom of the pearl ring 12. A second motor 15 is welded to the bottom of the rotating column 14. The preferred model of the second motor 15 is a Panasonic MADDT. The input terminal of the second motor 15 is electrically connected to the controller. (See attached...) Figure 4 As shown, a fixing column 17 is welded to the top wall of the inner box 1, a fixing ring 18 is welded to the middle of the fixing column 17, and several high-pressure nozzles 19 are welded to one side of the bottom of the fixing column 17. The input end of each high-pressure nozzle 19 is electrically connected to the output end of the controller. Several cameras 20 are welded to the bottom of the fixing column 17 away from the high-pressure nozzles 19. The preferred model of the camera 20 is Basler acA1920-40gc. The output end of each camera 20 is electrically connected to the input end of the controller. Since the detection of pearls depends on the imaging of the camera 20, in order to provide a bright imaging environment for the camera 20 to ensure clear imaging, an array light source is fixedly connected to the bottom of the fixing ring 18. The preferred model of the array light source is an LED lamp. The input end of the array light source is electrically connected to the output end of the controller.

[0044] After the pearl testing is completed, the tested pearls need to be collected as shown in the attached document. Figure 1 and attached Figure 4As shown, the housing 1 has an opening 21 on the side near the high-pressure nozzle 19. The opening 21 is provided with several collection channels 22 corresponding to the high-pressure nozzle 19. The collection channels 22 are S-shaped. The top of each collection channel 22 is fixedly connected to the side wall of the fixing ring 18. The top opening of each collection channel 22 is aligned with the corresponding high-pressure nozzle 19. The inner wall of each collection channel 22 is provided with an elastic layer.

[0045] The specific implementation process is as follows: When the pearls are transported to the pearl ring 12 through the conveyor channel 7, the controller receives the information about the pearls placed on the pearl ring 12 through the camera 20 and controls the second motor 15 to operate. At this time, the output shaft of the second motor 15 controls the rotating column 14 to rotate, and the rotating column 14 drives the pearl ring 12 to rotate. The controller automatically coordinates and controls the rotation speed of the pearl ring 12 and the transmission speed of the conveyor channel 7 so that the pearls are placed one by one in different grooves 13. The camera 20 takes pictures of each pearl. After the imaging information is transmitted to the controller, the controller records the position of the pearls according to the imaging information and detects the size and quality of the pearls. Then, the controller controls the pearl ring 12 to transport the pearls that meet the standards to the corresponding collection channel 22, and controls the high-pressure nozzle 19 corresponding to the collection channel 22 to blow the pearls into the corresponding collection channel 22, thus completing the sorting of pearls.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
