Technical Field

[0001] This invention relates to the field of fastener testing technology, and in particular to a follow-up testing, screening and separation device for fastener base processing and production. Background Technology

[0002] Fasteners are very common mechanical parts, often used to fasten structural components. Due to their diverse applications across industries including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, mold making, and hydraulics, they are among the most widely used basic mechanical components. In current fastener manufacturing processes, to ensure processing accuracy and production specifications, it is necessary to inspect the fasteners for dimensional and surface defects. The inspected fasteners are then screened and classified. Currently, most inspection methods are manual, which is not only time-consuming and labor-intensive but also prone to errors and omissions. Summary of the Invention

[0003] The technical problem that this invention aims to solve is that most current methods for testing fasteners are manual, which is not only time-consuming and labor-intensive, but also prone to false detections and missed detections.

[0009] A side discharge port is provided on the outer side of the main frame above the side-lifting collection box.

[0010] Side-mounted guide assembly frames are bolted to both sides of the side-lifting aggregate box on the outer side of the main frame. The upper end and the bottom of the side-mounted guide assembly frame are provided with loading and unloading ports. A side-mounted assembly groove is opened on the assembly surface of the side-mounted guide assembly frame and the side-lifting aggregate box. A side-mounted deceleration spring is installed inside the side-mounted assembly groove.

[0011] The lateral lifting collection box is connected to the upper surface of the lateral descent spring by inserting side guide blocks of an integrated structure on both sides into the side assembly slot.

[0026] 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.

[0027] 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.

[0028] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The device shown is a follow-up detection, screening and separation device for fastener base processing and production, including a main frame 1, an electrically controlled material conveying platform 2 installed on the upper surface of the main frame 1, a lateral circulation adjustment device 3 that operates synchronously with the electrically controlled material conveying platform 2 installed on the outer side of the main frame 1, a lateral telescopic screening mechanism 4 fixedly mounted on the lateral circulation adjustment device 3, and a lateral lifting collection box 5 installed on the outer side of the main frame 1.

[0029] To facilitate internal material conveying, the electrically controlled material conveying platform 2 includes an electrically controlled drive wheel 21, a follower support wheel 22, a flexible conveyor belt 23 fitted on the electrically controlled drive wheel 21 and the follower support wheel 22, and a detachable external support seat 24 fixed on the outside of the flexible conveyor belt 23.

[0030] The electrically controlled drive wheel 21 is existing technology, which drives the flexible conveyor belt 23 and the detachable external support 24 to transport the fastener base.

[0031] To facilitate synchronous adjustment, the lateral circulation adjustment device 3 includes a lateral support frame 31 fixedly installed on the outer side of the main frame 1, a lateral synchronous drive wheel 32 movably installed inside the lateral support frame 31, a lateral synchronous support wheel 33, a flexible synchronous conveyor belt 34, a transmission gear set 35 that synchronously connects the follower support wheel 22 and the lateral synchronous drive wheel 32, and an external mounting base 36 fixed on the outer side of the flexible synchronous conveyor belt 34.

[0032] The transmission gear set 35 includes a first gear axially fixed on the outer shaft of the follower support wheel 22 and a second gear axially fixed on the outer synchronous shaft of the lateral synchronous drive wheel 32. The first gear and the second gear mesh with each other for transmission.

[0033] To facilitate detection and screening, the lateral telescopic screening mechanism 4 includes a lateral assembly cylinder 41 fixed on the outer side of the external mounting base 36, an electrically controlled translation screw 42 fixed on the lateral assembly cylinder 41, a sliding adjustment cylinder 43 slidably assembled inside the lateral assembly cylinder 41, an internal thread adjustment block 44 fixed on the upper end of the sliding adjustment cylinder 43, a built-in rotary motor 45 fixed inside the sliding adjustment cylinder 43, a top rotating head 46 axially mounted on the outer end of the sliding adjustment cylinder 43, and an internal control module installed inside the top rotating head 46.

[0034] Both the electrically controlled translation screw 42 and the built-in rotary motor 45 are existing technologies. The electrically controlled translation screw 42 is used to rotate and drive the internal thread adjustment block 44 to translate and adjust, thereby controlling the sliding adjustment cylinder 43 to translate and squeeze into the main frame 1, thereby detecting and squeezing the fastener base located on the detachable external support 24.

[0035] To facilitate the inspection of the inside of the fastener base, the internal control module includes an embedded optical inspection probe 47 fixed on the outer arc surface of the top rotating head 46 and a top compression monitoring module 48 fixed on the outer plane of the top rotating head 47.

[0036] Both the embedded optical inspection probe 47 and the top extrusion monitoring module 48 are existing technologies. The embedded optical inspection probe 47 is used to inspect the inside of the fastener base while it is rotating, and is used to detect the inner diameter and surface defects. Since the mounting surface of the fastener base is inside, it mainly detects the internal parameters.

[0037] To facilitate lateral screening and separation, a lateral discharge port 6 is provided on the outer side of the main frame 1 above the lateral lifting collection box 5.

[0038] After the fastener base has been inspected, it is pressed towards the side discharge port 6 by the sliding adjustment cylinder 43, and thus falls into the side lifting collection box 5. Each side discharge port 6 is equipped with a prior art infrared positioning module, which cooperates with the prior art infrared receiver on the side assembly cylinder 41. In this way, the side telescopic screening mechanism 4 can determine the specification of the fastener base corresponding to the side discharge port 6 at its location.

[0039] To facilitate lateral loading and unloading, a side guide assembly frame 7 is bolted to both sides of the lateral lifting aggregate box 5 on the outer side of the main frame 1. The upper end and the bottom of the side guide assembly frame 7 are provided with loading and unloading ports 8. A side assembly groove 9 is opened on the assembly surface of the side guide assembly frame 7 and the lateral lifting aggregate box 5. A side descent spring 10 is installed inside the side assembly groove 9.

[0040] The loading and unloading port 8 on the bottom side adopts an oblique layout design, which makes it convenient to squeeze the side deceleration spring 10 when the side lifting collection box 5 is full, so that it slides out from the loading and unloading port on the bottom side.

[0041] To facilitate lateral assembly, the lateral lifting collection box 5 is connected to the upper surface of the lateral descent spring 10 by inserting the side guide block 11, which is an integral structure on both sides, into the lateral assembly slot 9.

[0042] In order to facilitate optical inspection of the outer surface of the fastener base from the outside and to inspect the specifications of the fastener base, an external inspection rod 12 is mounted on the outer wall of the internal thread adjustment block 44, and an external optical inspection probe 13 is mounted on the external inspection rod 12.

[0043] The external optical inspection probe 13 is existing technology. It uses photoelectric detection technology to perform optical inspection on the outer surface to determine the size and specifications of the fastener base.

[0044] Working principle: The electrically controlled conveying platform 2 moves the fastener base horizontally. Simultaneously, the electrically controlled conveying platform 2 drives the lateral circulation adjustment device 3. When the fastener base moves horizontally to align with the lateral telescopic screening mechanism 4, the lateral telescopic screening mechanism 4 is automatically controlled to extend into the fastener base by the existing infrared sensor switch on the adjacent side wall of the lateral assembly cylinder 41. At the same time as the extension, the top rotating head 46 rotates, controlling its internal control module to optically irradiate the inner wall of the fastener base. The external optical detection probe 13 located on the outside identifies the specifications of the fastener base, thereby squeezing fastener bases of different specifications into the lateral lifting collection box 5 at different positions. The last lateral lifting collection box 5 is used for waste collection. When unqualified products are detected, they are squeezed into the last lateral lifting collection box 5.

[0045] 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.
