[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Figure 1 , Figure 2 and Figure 3 The shown device is a conveying and screening device for fastener detection, comprising a horizontal main frame 1, a first electrically-controlled conveyor belt 2 and a second electrically-controlled conveyor belt 3. An upper internal fixed frame 4 for installing the first electrically-controlled conveyor belt 2, a middle screening layer 5 and a lower internal fixed frame 6 for installing the second electrically-controlled conveyor belt 3 are fixed inside the horizontal main frame 1. An electrically-controlled material guide plate 7 is movably mounted at the discharge end of the first electrically-controlled conveyor belt 2 inside the horizontal main frame 1. An optical detection module 8 is installed inside the electrically-controlled material guide plate inside the horizontal main frame 1.

[0029] In order to cooperate with the movable assembly, the inner wall of the horizontal main frame 1 is provided with a forward-protruding annular assembly frame 9 , and the optical detection module 8 is fixedly installed inside the annular assembly frame 9 .

[0030] In order to cooperate with the electric control adjustment, the electric controlled material guide disk 7 includes a flip adjustment disk 71 movably mounted on the outside of the annular assembly frame 9, a lateral adjustment motor 72 for controlling the rotation of the flip adjustment disk 71, a lateral assembly protrusion 73 fixed on the outer arc surface of the flip adjustment disk 71, a modular external material guide seat 74 mounted on the lateral assembly protrusion 73, an electric drive roller 75 movably mounted on the outer wall of one side of the modular external material guide seat 74, a support roller 76 movably mounted on the outer wall of the other side of the modular external material guide seat 74, and a first electric controlled arc support claw 77 and a second electric controlled arc support claw 78 movably mounted on the modular external material guide seat 74.

[0031] The modular external material guide seat 74 is slidably sleeved on the lateral assembly protrusion 73 to complete the assembly work with the outer side of the flip adjustment plate 71.

[0032] The first electrically controlled conveyor belt 2 is used to convey fasteners, while the second electrically controlled conveyor belt 3 is used to convey storage boxes for qualified parts. The first electrically controlled conveyor belt 2 conveys the fasteners to the right between two adjacent modular external guide seats 74 on the outer arc surface of the flip adjustment disk 71, and then the fasteners are stacked together, and the innermost horizontal fasteners are installed and limited between the two adjacent modular external guide seats 74 by starting the first electrically controlled arc support claw 77 and the second electrically controlled arc support claw 78 to flip outward. At this time, the fasteners rotate with the flip adjustment disk 71 to drop the excess fasteners back onto the first electrically controlled conveyor belt 2, and then the limited fasteners move upward and then perform optical inspection at the 11 o'clock to 1 o'clock position, and then the electric drive roller 75 and the support roller 76 respectively support the fasteners, and the electric drive roller 75 is used to control the rotation of the fasteners, thereby improving the inspection flip.

[0033] In order to facilitate installation, the modular external material guide seat 74 is provided with lateral turning grooves 10 at the installation ends corresponding to the first electrically-controlled arc-shaped supporting claw 77 and the second electrically-controlled arc-shaped supporting claw 78 .

[0034] In order to cooperate with the magnetically controlled flipping adjustment, the first electrically controlled arc-shaped supporting claw 77 and the second electrically controlled arc-shaped supporting claw 78 are both composed of an arc-shaped limiting claw 781 axially movably installed in the lateral flipping groove 10, an extrusion spring 782 and an embedded electromagnet 783.

[0035] The embedded electromagnet 783 controls the compression and expansion of the extrusion spring 782 by opening and closing, and controls the arc-shaped limiting claw 781 to perform flipping control by the compression and expansion of the extrusion spring.

[0036] In order to cooperate with infrared positioning and improve the accuracy of material feeding, the front end side wall of the flip adjustment disk 71 is provided with an infrared positioning seat 11 protruding forward, and an embedded infrared positioning module is installed inside the infrared positioning seat 11. An infrared signal transmitting module 13 matching the embedded infrared positioning module is fixedly installed on one side of the second electric-controlled conveyor belt 3 on the horizontal main frame 1.

[0037] When the flip adjustment disk 71 rotates, it will flip the infrared positioning seat 11 and the embedded infrared positioning module. Then the embedded infrared positioning module receives the signal from the infrared signal transmitting module 13. At this time, it will control the first electrically controlled arc supporting claw 77 and the second electrically controlled arc supporting claw 78 to start flipping as needed, and then drop qualified fasteners onto the storage box on the second electrically controlled conveyor belt 3, and unqualified fasteners onto the middle screening layer 5.

[0038] In order to cooperate with the detection, arc-shaped transparent windows 14 matching the optical detection module 8 are installed on both sides of the lateral assembly protrusions 73 outside the flip adjustment disk 71.

[0039] The surface of the fastener can be optically inspected through the arc-shaped transparent window 14, and the arc-shaped transparent window 14 can also be removed as needed.

[0040] In order to cooperate with the rotation adjustment, the lateral adjustment motor 72 is fixedly installed on the inner side of the annular assembly frame 9, and an annular adjustment groove is opened on the inner arc surface of the flip adjustment disk 71. An adjustment gear 15 that matches the annular adjustment groove is axially fixed on the adjustment shaft of the lateral adjustment motor 72.

[0041] The lateral adjustment motor 72 drives the adjustment gear 15 to rotate, thereby controlling the flip adjustment disk 71 to rotate, and the adjustment gear 15 is meshed with the annular adjustment tooth groove for transmission.

[0042] In order to cooperate with automatic control of opening and closing, a pressure control module 16 is installed at the connecting end of the support roller 76.

[0043] When the flip adjustment disk 71 rotates clockwise, the fastener will be controlled to flip upward along with the flip adjustment disk 71, and then the fastener will be squeezed on the electric drive roller 75. Then, when the flip adjustment disk 71 is lifted to the specified position with the fastener, the fastener will be pressed on the support roller 76. At this time, the pressure control module 16 will start the optical detection module 8 and start optical recognition scanning of the fastener in the rotating process.

[0044] In order to improve the installation stability of the modular external material guiding seat 74 , an elastic limiting block 17 for limiting the modular external material guiding seat 74 is elastically assembled inside the lateral assembly protrusion 73 .

[0045] The elastic limit block 17 is composed of a telescopic limit block slidably assembled in the telescopic hole inside the lateral assembly protrusion 73 and a return spring installed on the outside of the telescopic limit block. The return spring controls the telescopic limit block to extend outward, thereby laterally limiting the modular external material guide seat 74 from the outside.

[0046] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
