Abstract
Description
Technical Field
[0001] This application relates to the field of sorting machine technology, and in particular to a size sorting machine that is easy to feed. Background Technology
[0002] Optical size sorting machines are automated inspection equipment based on optical imaging and image processing technology. They are mainly used in industrial production to quickly and accurately measure and sort the external dimensions and appearance defects of products. When inspecting products, the sorting machine feeds the products onto the turntable inside the sorting machine through a feeding mechanism. As the turntable rotates, the CCD industrial camera around the turntable images and inspects the products on the turntable. In order to meet the requirements of high imaging effect, the turntable of the sorting machine is usually a glass turntable.
[0003] Headphones, speakers, and other sound-producing devices typically require magnetic strips. However, the magnetic strips in small headphones are small and lightweight. When the magnetic strips are fed to the turntable by the feeding mechanism, the smooth surface of the turntable results in low friction, making it easy for the magnetic strips to slip off the turntable. Furthermore, during the testing process, the magnetic strips can easily be thrown off the turntable or deviate from the optimal imaging area of the CCD camera due to centrifugal force. This requires staff to manually restore the magnetic strips to their testing position, affecting testing efficiency. Utility Model Content
[0004] This application provides a size sorting machine that facilitates material feeding.
[0005] The size sorting machine for easy feeding provided in this application adopts the following technical solution:
[0006] A size sorting machine for easy feeding includes a housing, a feeding mechanism, a screening mechanism, a stop mechanism, and a discharge mechanism. A platform is disposed inside the housing, and the screening mechanism and the discharge mechanism are disposed on the platform. The discharge mechanism is located outside the housing and connected to the screening mechanism. The feeding mechanism includes a vibrating disc, a conveyor belt, and an auxiliary feeding platform connected in sequence. The auxiliary feeding platform forms a downward slope, and a first discharge baffle is disposed on the inner side of the downward slope. The screening mechanism includes multiple sets of CCD cameras and a circular turntable driven by a motor. The multiple sets of CCD cameras are arranged in a ring around the screen. The turntable is located on the outer periphery of the turntable and between the auxiliary feeding platform and the discharge mechanism. The upper surface of the turntable is connected to the lower end of the lower slope. The stop mechanism includes a first support frame and a second feeding baffle connected to the first support frame. The second feeding baffle surrounds the outer periphery of the turntable and is connected to the auxiliary feeding platform, and is located on the outer side of the lower slope. The first discharge baffle and the second feeding baffle form an arc-shaped feeding channel for guiding the magnetic strip. A magnetic ring is provided on the lower surface of the turntable corresponding to the arc-shaped feeding channel. The magnetic ring is coaxially connected to the turntable.
[0007] Preferably, the discharge mechanism includes a receiving hopper and a solenoid valve. The receiving hopper is located on the outer periphery of the turntable, with its opening facing the center of the turntable. A flexible buffer pad is provided inside the receiving hopper. The solenoid valve is located above the turntable, and its air outlet faces the magnetic ring along the direction from the center to the edge of the turntable.
[0008] Preferably, the receiving hopper is provided with a symmetrical first discharge baffle and a second discharge baffle on both sides, and the first discharge baffle and the second discharge baffle surround the outer periphery of the turntable.
[0009] Preferably, it further includes a guiding mechanism, which includes a second support frame and a guide disk connected to the second support frame. The guide disk has a circular structure and is connected to the upper surface of the turntable and located outside the magnetic ring.
[0010] Preferably, it also includes a receiving tray, which is disposed on the platform and located below the turntable, and is coaxially arranged with the turntable.
[0011] In summary, this application includes at least one of the following beneficial technical effects:
[0012] 1. This application forms an arc-shaped feeding channel corresponding to a magnetic ring. During the process of the magnetic strip entering the turntable, it is guided by the first and second feeding baffles to the circumference of the magnetic ring. The magnetic ring attracts the magnetic strip with magnetic force, aligning the magnetic strips in the same circumferential position. During the rotation of the turntable, it provides an attractive force to overcome centrifugal force, making it less likely for the magnetic strip to fall off the turntable or deviate from the optimal imaging area of the CCD camera during feeding and detection. Technicians also do not need to pick up the magnetic strip due to positional deviation or premature removal from the turntable, thus ensuring the detection efficiency of the magnetic strip.
[0013] 2. By setting a first discharge baffle and a second discharge baffle, after the magnetic strip is detected by the CCD camera, the gas output by the solenoid valve blows it away from the turntable and into the receiving bin. The first discharge baffle and the second discharge baffle are used to prevent the magnetic strip from falling off the turntable when the driving direction of the magnetic strip is deviated due to the excessive airflow diameter of the solenoid valve. A flexible buffer pad is set to provide cushioning for the magnetic strip and prevent the magnetic strip from being damaged due to collision with the inner wall of the receiving bin, thus ensuring the yield of the magnetic strip.
[0014] 3. By setting a guiding mechanism, the magnetic strip that has deviated from its position is guided to move to the magnetic ring area, further preventing the magnetic strip from falling off. Attached Figure Description

[0022] The present application will be further described in detail below with reference to the accompanying drawings.
[0023] This application provides a size sorting machine that facilitates material feeding, such as... Figures 1 to 6As shown, the device includes a housing 1, a feeding mechanism 2, a screening mechanism 3, a stop mechanism 4, and a discharge mechanism 5. A platform 11 is installed inside the housing 1. The screening mechanism 3 and the discharge mechanism 5 are mounted on the platform 11. The discharge mechanism 5 is located outside the housing 1 and connected to the screening mechanism 3. A batch of magnetic strips enters the screening mechanism 3 via the feeding mechanism 2, and the screening mechanism 3 detects the pass rate of the magnetic strips. After being detected, all magnetic strips are sequentially discharged from the screening mechanism 3 by the discharge mechanism 5, thus completing the screening of a batch of magnetic strips. The feeding mechanism 2 includes a vibrating plate 21, a conveyor belt 22, and an auxiliary feeding platform 23 connected in sequence. The vibrating plate 21 and the conveyor belt 22 are existing technologies. The auxiliary feeding platform 23 forms a downward slope 231, and a first discharge baffle 5 is installed on the inner side of the downward slope 231. 3. The screening mechanism 3 includes multiple sets of CCD cameras 31 and a circular glass turntable 32 driven by a motor. The multiple sets of CCD cameras 31 are arranged around the outer periphery of the turntable 32 and located between the auxiliary feeding platform 23 and the discharge mechanism 5, for visual inspection of magnetic strips. The upper surface of the turntable 32 is connected to the lower end of the lower slope 231. Specifically, the inner side of the lower slope 231 refers to the side of the auxiliary feeding platform 23 near the middle of the turntable 32. The upper surface of the turntable 32 is in close contact with the lower end of the lower slope 231. When the turntable 32 rotates, it will not drive the auxiliary feeding platform 23 to rotate. The stop mechanism 4 includes a first support frame 41 and a second feeding baffle 42 connected to the first support frame 41. The first support frame 41 is fixed on the platform 11, and the second feeding baffle 42 is connected to the platform 11. Plate 42 surrounds the outer periphery of turntable 32 and is connected to auxiliary feeding platform 23, located outside the lower slope 231. The first discharge baffle 53 and the second feeding baffle 42 form an arc-shaped feeding channel for guiding the magnetic strips. A magnetic ring 6 is provided on the lower surface of turntable 32 corresponding to the arc-shaped feeding channel. The magnetic ring 6 is coaxially connected to turntable 32, and the magnetic ring 6 and the optimal imaging area of CCD camera 31 are located on the same circumference. A certain number of magnetic strips are first fed into vibrating plate 21. After vibration, the magnetic strips can be evenly arranged and transported by conveyor belt 22, and slide down from the lower slope 231 of auxiliary feeding platform 23. Since turntable 32 is driven to rotate by motor during detection, the magnetic strips pass through the arc-shaped feeding channel formed by the first feeding baffle 232 and the second feeding baffle 42. Furthermore, the magnetic ring 6 can attract the magnetic strip through magnetic force during its descent, thus improving the stability of the magnetic strip as it rotates on the turntable 32. After being imaged and detected by the CCD camera 31, it is sent away from the turntable 32 by the discharge mechanism 5. In this way, during the process of the magnetic strip entering the turntable 32, it is guided by the first feeding baffle 232 and the second feeding baffle 42 to the circumference of the magnetic ring 6. The magnetic ring 6 attracts the magnetic strip through magnetic force, aligning the magnetic strips in the same circumferential position. During the rotation of the turntable 32, it provides an attractive force to overcome centrifugal force, making it less likely for the magnetic strip to fall off the turntable 32 or deviate from the optimal imaging area of the CCD camera 31 due to its small size and weight during feeding and detection. Technicians also do not need to pick up the magnetic strip if it is misaligned or prematurely removed from the turntable 32.This ensures the detection efficiency of the magnetic strip.
[0024] like Figures 2 to 6 As shown, the discharge mechanism 5 includes a receiving bin 51 and a solenoid valve 52. The receiving bin 51 is located on the outer periphery of the turntable 32, with its opening facing the center of the turntable 32. A flexible buffer pad 55 is provided inside the receiving bin 51. The solenoid valve 52 is located above the turntable 32, and its outlet faces the magnetic ring 6 along the direction from the center to the edge of the turntable 32. Symmetrical first discharge baffles 53 and second discharge baffles 54 are respectively provided on both sides of the receiving bin 51, surrounding the turntable 32. After the magnetic strip is detected by the CCD camera 31, the gas output by the solenoid valve 52 blows it away from the turntable 32 and into the receiving hopper 51. The first discharge baffle 53 and the second discharge baffle 54 are used to prevent the magnetic strip from falling off the turntable 32 when the driving direction of the magnetic strip is deviated due to the large airflow diameter of the solenoid valve 52. Since the external force applied to the magnetic strip by the airflow of the solenoid valve 52 is usually large, a flexible buffer pad 55 is set to provide buffer for the magnetic strip and prevent the magnetic strip from being damaged due to collision with the inner wall of the receiving hopper 51, thus ensuring the yield of the magnetic strip.
[0025] like Figure 2 and Figure 3 As shown, the size sorting machine of this application, which facilitates feeding, also includes a guiding mechanism 7 and a receiving tray 8. The guiding mechanism 7 includes a second support frame 71 and a guide disk 72 connected to the second support frame 71. The guide disk 72 has a circular structure and is connected to the upper surface of the turntable 32 and located outside the magnetic ring 6. The guide disk 72 is attached to the upper surface of the turntable 32. When the turntable 32 rotates, it does not drive the guide disk 72 to rotate. The edge of the guide disk 72 is located at the same circumferential position as the outer edge of the magnetic ring 6. The guide disk 72 is used to guide the magnetic strips that have deviated from their positions to move to the area of the magnetic ring 6, further preventing the magnetic strips from falling. The receiving tray 8 is set on the platform 11 and is located below the turntable 32 and coaxially arranged with the turntable 32. It is used to receive the fallen magnetic strips. When the magnetic strips fall due to external force, the receiving tray 8 can receive these magnetic strips, saving the operator the effort of searching for magnetic strips in various instruments.
[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
