Description

Technical Field

[0001] The present invention relates to the technical field of fastener conveying and detection, and in particular to a synchronous detection and screening device for fastener conveying. Background Art

[0002] Fasteners are hardware components that ensure the normal operation and maintain the structure of equipment through connection and fixation. They can effectively prevent connection loosening, absorb and relieve vibrations and impacts generated during equipment operation, and protect the equipment from damage.

[0003] Fasteners are widely used in industries such as energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, molds, and hydraulics. During the production process, in order to cooperate with fastener production, it is necessary to control the conveying and switching of fasteners between different equipment, and it is also necessary to detect the fasteners after production and processing. At present, due to the large number of fasteners, the detection is very difficult. If detected one by one manually, it will consume a great deal of time and cost, which is very unrealistic. At present, the existing optical detection equipment cannot be directly integrated onto the conveying equipment, resulting in low compatibility with the existing conveying equipment and very troublesome transformation and upgrading. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that at present, due to the large number of fasteners, the detection is very difficult. If detected one by one manually, it will consume a great deal of time and cost, which is very unrealistic.

[0030] Figure 1 , Figure 2 , Figure 3 and Figure 4 A synchronous detection and screening device for fastener conveying shown in Figure 2 , Figure 3 , Figure 4 and includes a horizontal main frame 1 and an electrically controlled conveyor belt 2 installed on the horizontal main frame 1. An internal horizontal guide plate 3 is fixedly assembled inside the horizontal main frame 1 and inside the electrically controlled conveyor belt 2. One end side wall of the internal horizontal guide plate 3 has an electrically controlled side guide frame 4 with an inverted L-shaped structure bent upward. The other end side wall of the internal horizontal guide plate 3 has an electrically controlled outer guide frame 5 bent upward. Two groups of inclined translation guide conveyor belts 6 with different heights are movably installed on the upper surface of the internal horizontal guide plate 3. Internal detection devices 7 are fixedly installed around the inclined translation guide conveyor belts 6 at the upper end of the internal horizontal guide plate 3.

[0031] To cooperate with the feeding, the electrically controlled side guide frame 4 includes a first longitudinal feeding pipe 41 fixedly installed on one end side wall of the internal horizontal guide plate 3, an upper electrically controlled adjustment cover 42 movably sleeved on the upper end of the first longitudinal feeding pipe 41, and a side guide baffle 43 fixed on the outer arc surface of the upper electrically controlled adjustment cover 42.

[0032] The electrically controlled conveyor belt 2 drives the fasteners to translate, and then is guided into the first longitudinal feeding pipe 41 by the side guide baffle 43, falls through the first longitudinal feeding pipe 41 onto the inclined translation guide conveyor belt 6 at the bottom, and then moves to the electrically controlled outer guide frame 5 by the inclined translation guide conveyor belt 6. Finally, it falls back onto the electrically controlled conveyor belt 2 through the electrically controlled outer guide frame 5.

[0033] To cooperate with lifting the fasteners upward and laterally distributing them, the electrically controlled outer guide frame 5 includes a second longitudinal feeding pipe 51 fixed on the other end side wall of the internal horizontal guide plate 3, an upper electrically controlled distribution cover 52 movably installed at the top of the second longitudinal feeding pipe 51, a longitudinal electrically controlled lifting belt 53 movably installed on the inner wall of the second longitudinal feeding pipe 51, and a transverse electrically controlled lifting belt 54 movably installed on the inner wall of the upper electrically controlled distribution cover 52.

[0034] The inclined translation guiding conveyor belt 6 controls the translation of the fasteners to the feeding port at the lower end of the second longitudinal discharging pipe 51, and then the longitudinally arranged lifting belt 53 lifts the fasteners upward through the second longitudinal discharging pipe 51. Then, when the fasteners are lifted to the position of the upper electric control material distributing cover 52, the horizontally arranged electric control lifting belt 54 discharges the fasteners horizontally along the upper electric control material distributing cover 52 and then discharges them to the electric control conveyor belt 2 from the outermost side.

[0035] In order to cooperate with the flipping of the fasteners, an inclined turning plate 8 is installed on the upper surface of the built-in horizontal guiding plate 3 between two groups of inclined translation guiding conveyor belts 6 with different heights.

[0036] The fasteners fall from the upper inclined translation guiding conveyor belt 6 onto the inclined turning plate 8, causing the upper surface of the fasteners to transfer to the lower surface. Then, the fasteners slide along the inclined turning plate 8 onto the lower inclined translation guiding conveyor belt 6, completing the switching of the front and back sides of the fasteners.

[0037] In order to cooperate with optical detection and side hole material dialing, the built-in detection device 7 includes a peripheral assembly frame 71 with an n-shaped structure fixedly installed at the upper end of the built-in horizontal guiding plate 3, three optical detection probes 72 fixedly installed on the peripheral assembly frame 71, and a magnetically controlled material screening and separating plate 73 installed on the side wall of the peripheral assembly frame 71.

[0038] The optical detection probes 72 scan the upper surface and outer side of the fasteners through the existing optical scanning technology to detect the surface wear degree and size of the fasteners. When problems are detected in the fasteners, the electromagnets on the magnetically controlled material screening and separating plate 73 are activated, and the material screening plate located outside the peripheral assembly frame 71 is controlled by an iron spring to peel the fasteners outward from the inclined translation guiding conveyor belt 6 to complete the material screening operation.

[0039] In order to cooperate with angle adjustment, the upper electric control adjustment cover 42 includes a top assembly cover 421 movably sleeved on the upper end of the first longitudinal discharging pipe 41, a side-mounted adjustment motor 422 fixed on the side wall of the top assembly cover 421, and a worm and gear assembly for drivingly connecting the first longitudinal discharging pipe 41 and the top assembly cover 421.

[0040] The side-mounted adjustment motor 422 is in meshing transmission with the worm on its rotating shaft and the worm gear on the outer arc surface of the first longitudinal discharging pipe 41 to form a worm and gear assembly. By driving the side-mounted adjustment motor 422, the top assembly cover 421 is controlled to rotate and adjust along the first longitudinal discharging pipe 41.

[0041] To cooperate with the top angle adjustment, the upper electric control material distribution cover 52 includes a top-mounted assembly disk 521 movably sleeved on the top end of the second longitudinal material discharge pipe 51, a horizontal material distribution pipe 522 fixed on the outer side of the top-mounted assembly disk 521, an external adjustment motor 523 fixed on the outer side surface of the horizontal material distribution pipe 522, and an adjustment rotating gear 524 axially installed on the lower rotating shaft of the external adjustment motor 523.

[0042] An annular tooth groove meshing with the adjustment rotating gear 524 is provided on the outer arc surface of the second longitudinal material discharge pipe 51. The external adjustment motor 523 drives the horizontal material distribution pipe 522 to rotate along the outer side of the second longitudinal material discharge pipe 51 by driving the adjustment rotating gear 524.

[0043] To cooperate with the lifting and lateral adjustment of the fasteners, lateral material pushing plates 9 are installed on the side walls of both the longitudinal electric control lifting belt 53 and the transverse electric control lifting belt 54.

[0044] The longitudinal electric control lifting belt 53 drives the lateral material pushing plate 9 on its surface to lift the low-position fasteners upward along the second longitudinal material discharge pipe 51, while the transverse electric control lifting belt 54 drives the lateral material pushing plate 9 on its surface to laterally strip outward the fasteners lifted upward by the longitudinal electric control lifting belt 53, and then discharges them from the material discharge port located at the lower outer side of the horizontal material distribution pipe 522.

[0045] The longitudinal electric control lifting belt 53 and the transverse electric control lifting belt 54 rotate at the same speed, and the lateral material pushing plates 9 on the side walls of the longitudinal electric control lifting belt 53 and the transverse electric control lifting belt 54 are arranged in a staggered manner and do not affect each other.

[0046] To cooperate with the lateral assembly, lateral assembly frames 10 are provided on both sides of the longitudinal electric control lifting belt 53 on the side wall of the second longitudinal material discharge pipe 51 and on both sides of the transverse electric control lifting belt 54 on the side wall of the upper electric control material distribution cover 52.

[0047] To cooperate with the extension and improve the adaptability, an embedded extension frame 11 is slidably assembled on the material receiving surface side wall of the side guide baffle 43, and an electric control screw rod 12 for controlling the embedded extension frame 11 is fixedly assembled on the material discharging surface side wall of the side guide baffle 43.

[0048] The embedded extension frame 11 is threadedly assembled with the electric control screw rod 12 by sleeving the inner-threaded extension block on the back of the embedded extension frame 11 on the electric control screw rod 12.

[0049] Inspired by the ideal embodiments of the present invention described above, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention.
