A synchronous detection screening device for fastener conveying

Abstract

This invention relates to the field of fastener conveying and inspection technology, and in particular to a synchronous inspection and screening device for fastener conveying, comprising a horizontal main frame and an electrically controlled conveyor belt mounted on the horizontal main frame. The synchronous inspection and screening device for fastener conveying utilizes a built-in transverse guide plate installed inside the conveying equipment. Then, it forms a U-shaped loop using electrically controlled lateral guide frames and an electrically controlled outer guide frame that bend upwards at both ends. This allows fasteners to be laterally guided away, optically inspected and identified internally, and then guided back to the conveying equipment, significantly improving inspection efficiency. By employing two sets of inclined, horizontally moving guide conveyors of different heights, multi-faceted inspection of fasteners can be performed, increasing the optical inspection range and improving inspection accuracy. This device can be directly integrated into existing conveying equipment, greatly improving adaptability and facilitating upgrades and modifications.

Description

Technical Field

[0001] This invention relates to the field of fastener conveying and inspection technology, and in particular to a synchronous inspection screening device for fastener conveying. Background Technology

[0002] Fasteners are hardware components used to connect and secure equipment, ensuring its proper functioning and structural integrity. They effectively prevent loosening of connections and absorb and mitigate vibrations and shocks generated during equipment operation, protecting the equipment from damage.

[0003] Fasteners are widely used in industries such as energy, electronics, electrical appliances, machinery, chemicals, metallurgy, mold making, and hydraulics. During production, to facilitate fastener manufacturing, it's necessary to control the transfer and switching of fasteners between different devices. Furthermore, the produced and processed fasteners require inspection. Currently, the sheer number of fasteners makes inspection very difficult. Manually inspecting each one would be extremely time-consuming and costly, making it impractical. Current optical inspection equipment cannot be directly integrated into conveyor equipment, resulting in poor compatibility with existing conveyor systems and making upgrades and modifications very complicated. Summary of the Invention

[0004] The technical problem that this invention aims to solve is that fasteners are numerous and difficult to inspect. Manually inspecting each one would be extremely time-consuming and costly, which is impractical. Furthermore, current optical inspection equipment cannot be directly integrated into conveying equipment, resulting in poor compatibility with existing conveying equipment and making modification and upgrading very troublesome.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a synchronous detection screening device for fastener conveying, comprising a horizontal main frame and an electrically controlled conveyor belt installed on the horizontal main frame. An internal transverse guide plate is fixedly assembled on the inner side of the horizontal main frame, located inside the electrically controlled conveyor belt. One side wall of the internal transverse guide plate has an electrically controlled lateral guide frame with an upwardly bent inverted L-shaped structure, and the other side wall of the internal transverse guide plate has an electrically controlled outer guide frame with an upwardly bent structure. Two sets of inclined translational guide conveyor belts with different heights are movably installed on the upper surface of the internal transverse guide plate. An internal detection device is fixedly installed on the upper surface of the internal transverse guide plate, located outside the inclined translational guide conveyor belts.

[0006] The electrically controlled side guide frame includes a first longitudinal feed pipe fixedly installed on one side wall of the built-in transverse guide plate, an upper electrically controlled adjustment cover movably sleeved on the upper end of the first longitudinal feed pipe, and a side guide baffle fixed on the outer arc surface of the upper electrically controlled adjustment cover.

[0007] The electrically controlled outer guide frame includes a second longitudinal feeding pipe fixed on the side wall of the other end of the built-in transverse guide plate, an upper electrically controlled material distribution cover movably installed at the top of the second longitudinal feeding pipe, a longitudinal electrically controlled lifting belt movably installed on the inner wall of the second longitudinal feeding pipe, and a transverse electrically controlled lifting belt movably installed on the inner wall of the upper electrically controlled material distribution cover.

[0008] An inclined tilting plate is installed on the upper surface of the built-in transverse guide plate between two sets of inclined translational guide conveyor belts of different heights.

[0009] The built-in detection device includes an n-shaped outer assembly frame fixedly installed on the upper end of the built-in horizontal guide plate, a plurality of optical detection probes fixedly installed on the outer assembly frame, and a magnetically controlled material-dispensing screen plate installed on the side wall of the outer assembly frame.

[0010] The upper electrically controlled adjustment cover includes a top mounting cover movably sleeved on the upper end of the first longitudinal feed tube, a side-mounted adjustment motor fixed on the side wall of the top mounting cover, and a worm gear assembly for driving the connection between the first longitudinal feed tube and the top mounting cover.

[0011] The upper electrically controlled material distribution cover includes a top assembly plate movably sleeved on the top of the second longitudinal material feeding pipe, a horizontal material distribution pipe fixed on the outside of the top assembly plate, an external adjustment motor fixed on the outer surface of the horizontal material distribution pipe, and an adjustment rotating gear axially mounted on the lower shaft of the external adjustment motor.

[0012] Both the longitudinal and transverse electrically controlled lifting belts are equipped with lateral material feeding plates on their side walls.

[0013] The second longitudinal feed pipe sidewalls located on both sides of the longitudinal electrically controlled lifting belt and the upper electrically controlled material distribution cover sidewalls located on both sides of the transverse electrically controlled lifting belt both have lateral assembly frames.

[0014] An embedded extension frame is slidably mounted on the material-facing side wall of the side guide baffle, and an electric control screw for controlling the embedded extension frame is fixedly mounted on the material-returning side wall of the side guide baffle.

[0015] The beneficial effects of this invention are:

[0016] (1) The present invention provides a synchronous detection screening device for fastener conveying by using a built-in transverse guide plate installed inside the conveying equipment, and then using the electrically controlled side guide frame and the electrically controlled outer guide frame bent upward at both ends to form a U-shaped loop, thereby guiding the fasteners to be guided away laterally and then optically detected and identified inside, and then guiding them back to the conveying equipment, which greatly improves its detection efficiency.

[0017] (2) By using two sets of inclined translational guide conveyor belts with different heights, fasteners can be inspected from multiple angles, improving the optical inspection range and inspection accuracy;

[0018] (3) This device can be directly integrated and installed on existing material conveying equipment, which greatly improves adaptability and facilitates transformation and upgrading;

[0019] (4) An angle-adjustable structure design is adopted in the electrically controlled side guide frame and the electrically controlled outer guide frame, which allows operation of the fasteners on the upper surface of the electrically controlled conveyor belt, greatly facilitating material laying and guiding.

[0020] (5) The entire equipment can be flipped outward as needed, so that the normal conveying operation can be maintained during idle time;

[0021] (6) An inclined flipping plate is installed between two sets of inclined translational guide conveyors of different heights, which can be flipped and adjusted when the fastener is switched, thus greatly facilitating the adjustment of the fastener on the front and back, thereby improving the detection range.

[0022] (7) Multi-directional optical scanning technology is used to improve detection efficiency, eliminating the need for manual operation. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] Figure 1 , Figure 2 , Figure 3 and Figure 4 The device shown is a synchronous detection screening device for fastener conveying, including a horizontal main frame 1 and an electrically controlled conveyor belt 2 mounted on the horizontal main frame 1. An internal transverse guide plate 3 is fixedly mounted on the inner side of the horizontal main frame 1, located inside the electrically controlled conveyor belt 2. One side wall of the internal transverse guide plate 3 has an electrically controlled lateral guide frame 4 with an upwardly bent inverted L-shaped structure, and the other side wall of the internal transverse guide plate 3 has an electrically controlled outer guide frame 5 with an upwardly bent structure. Two sets of inclined translational guide conveyor belts 6 with different heights are movably mounted on the upper surface of the internal transverse guide plate 3. An internal detection device 7 is fixedly mounted on the upper end of the internal transverse guide plate 3, located around the inclined translational guide conveyor belts 6.

[0031] To facilitate material feeding, the electrically controlled side guide frame 4 includes a first longitudinal feeding pipe 41 fixedly installed on one side wall of the built-in transverse 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 moves the fasteners horizontally, and then is guided by the side guide baffle 43 to the first longitudinal discharge pipe 41. It falls through the first longitudinal discharge pipe 41 onto the inclined horizontal guide conveyor belt 6 at the bottom, and then moves from the inclined horizontal guide conveyor belt 6 to the electrically controlled outer guide frame 5. Finally, it falls back onto the electrically controlled conveyor belt 2 through the electrically controlled outer guide frame 5.

[0033] To facilitate the upward lifting and horizontal material distribution of fasteners, the electrically controlled outer guide frame 5 includes a second longitudinal feed pipe 51 fixed to the side wall of the other end of the built-in horizontal guide plate 3, an upper electrically controlled material distribution cover 52 movably installed at the top of the second longitudinal feed pipe 51, a longitudinal electrically controlled lifting belt 53 movably installed on the inner wall of the second longitudinal feed pipe 51, and a horizontal electrically controlled lifting belt 54 movably installed on the inner wall of the upper electrically controlled material distribution cover 52.

[0034] The inclined translational guide conveyor belt 6 controls the fastener to move horizontally to the feed port at the lower end of the second longitudinal feed pipe 51. Then, the longitudinal lifting belt 53 lifts the fastener upward through the second longitudinal feed pipe 51. When the fastener is lifted to the position of the upper electrically controlled material distribution cover 52, the transverse electrically controlled lifting belt 54 discharges the fastener laterally along the upper electrically controlled material distribution cover 52, and then discharges it from the outermost side onto the electrically controlled conveyor belt 2.

[0035] To facilitate the flipping of fasteners, an inclined flipping plate 8 is installed on the upper surface of the built-in transverse guide plate 3 between two sets of inclined translational guide conveyor belts 6 at different heights.

[0036] The fastener falls from the upper inclined translational guide conveyor belt 6 onto the inclined flip plate 8, causing the upper surface of the fastener to transfer to the lower surface. Then, the fastener slides down along the inclined flip plate 8 onto the lower inclined translational guide conveyor belt 6, completing the switching of the front and back sides of the fastener.

[0037] To facilitate optical inspection and side-hole material feeding, the built-in inspection device 7 includes an n-shaped outer assembly frame 71 fixedly installed on the upper end of the built-in transverse guide plate 3, three optical inspection probes 72 fixedly installed on the outer assembly frame 71, and a magnetically controlled material feeding screen plate 73 installed on the side wall of the outer assembly frame 71.

[0038] The optical inspection probe 72 scans the upper and outer surfaces of the fastener using existing optical scanning technology to detect the surface wear and dimensions of the fastener. When a problem is detected in the fastener, the electromagnet on the magnetically controlled material feeding screen plate 73 is activated. Through the iron spring, the screening plate located outside the outer assembly frame 71 peels the fastener outward and moves it to the inclined horizontal guide conveyor belt 6 to complete the screening operation.

[0039] To facilitate angle adjustment, the upper electrically controlled adjustment cover 42 includes a top mounting cover 421 movably sleeved on the upper end of the first longitudinal feed tube 41, a side-mounted adjustment motor 422 fixed on the side wall of the top mounting cover 421, and a worm gear assembly for driving the connection between the first longitudinal feed tube 41 and the top mounting cover 421.

[0040] The side-mounted adjustment motor 422 engages with the worm gear on its shaft and the worm wheel on the outer arc surface of the first longitudinal feed tube 41 to form a worm gear assembly. The top mounting cover 421 is rotated and adjusted along the first longitudinal feed tube 41 by driving the side-mounted adjustment motor 422.

[0041] To accommodate the top angle adjustment, the upper electrically controlled material distribution cover 52 includes a top assembly plate 521 movably sleeved on the top of the second longitudinal feeding pipe 51, a horizontal material distribution pipe 522 fixed on the outside of the top assembly plate 521, an external adjustment motor 523 fixed on the outer surface of the horizontal material distribution pipe 522, and an adjustment rotating gear 524 axially mounted on the lower shaft of the external adjustment motor 523.

[0042] An annular toothed groove is provided on the outer arc surface of the second longitudinal feed pipe 51 to mesh with the adjusting rotating gear 524. The external adjusting motor 523 drives the horizontal feed pipe 522 to rotate along the outer side of the second longitudinal feed pipe 51 by driving the adjusting rotating gear 524.

[0043] To facilitate the lifting and lateral adjustment of the fasteners, lateral material-pulling plates 9 are installed on the side walls of both the longitudinally placed electrically controlled lifting belt 53 and the transversely placed electrically controlled lifting belt 54.

[0044] The longitudinally placed electrically controlled lifting belt 53 lifts the low-position fasteners upward along the second longitudinal feed pipe 51 by driving the lateral material-pulling plate 9 on its surface, while the transverse electrically controlled lifting belt 54 peels the fasteners lifted by the longitudinally placed electrically controlled lifting belt 53 outward laterally by driving the lateral material-pulling plate 9 on its surface, and then discharges them from the feed port located at the lower end of the outer side of the transverse feed pipe 522.

[0045] The longitudinally placed electrically controlled lifting belt 53 and the transversely placed electrically controlled lifting belt 54 rotate at the same speed. The lateral material-pulling plates 9 on the side walls of the longitudinally placed electrically controlled lifting belt 53 and the transversely placed electrically controlled lifting belt 54 are staggered and will not affect each other.

[0046] To facilitate lateral assembly, the sidewalls of the second longitudinal feed pipe 51 located on both sides of the longitudinal electrically controlled lifting belt 53 and the sidewalls of the upper electrically controlled material distribution cover 52 located on both sides of the transverse electrically controlled lifting belt 54 both have lateral assembly frames 10.

[0047] To facilitate extension and improve adaptability, an embedded extension frame 11 is slidably mounted on the side wall of the material-facing side of the side guide baffle 43, and an electric control screw 12 for controlling the embedded extension frame 11 is fixedly mounted on the side wall of the material-rearing side of the side guide baffle 43.

[0048] The embedded extension frame 11 is threaded onto the electric control screw 12 via an internal threaded extension block on its back.

[0049] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
