Description

Technical Field

[0001] This utility model relates to the field of nut conveying technology, specifically a shaped nut conveying device. Background Technology

[0002] The forming nut conveying equipment is an automated device that automatically and accurately transports forming nuts to a designated workstation for subsequent assembly operations.

[0003] Currently, in the field of automation, the conveying and orientation of formed nuts mainly relies on vibratory feeder equipment. This technology uses electromagnets or motors to drive the feeder to generate high-frequency micro-amplitude vibrations. The nuts are driven along the spiral track by the vibration inertia and track friction. Various orientation mechanisms set on the track are used to screen and arrange them. However, its working mechanism determines that the nuts must undergo continuous vibration, throwing, and frequent collisions and friction with the feeder, track, and other nuts during the conveying process. This not only generates huge environmental noise, but also inevitably causes scratches, dents, and other damage to the surface of the nuts (especially the precision-machined or electroplated surfaces), seriously affecting the product yield and making it difficult to meet the high-standard manufacturing scenarios with stringent surface quality requirements. Utility Model Content

[0004] The purpose of this invention is to provide a forming nut conveying device to solve the problems of nut surface damage and noise.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a forming nut conveying device, comprising a rotating structure, a drive motor connected to a first rotating shaft, a rotating track connected to the first rotating shaft, a rotating wheel connected to the rotating track, and a plurality of arrayed scraping grooves on the inner circumference of the rotating wheel. The rotating structure also includes a conveying structure with a gear set driven by the drive motor, the gear set connected to a rotating track, the rotating track surrounding the upper and outer sides of the rotating wheel, and a plurality of nut holders along its path on the inner side of the rotating track. The front end of the rotating structure also includes a calibration structure with a drive guide rail, a slider slidably mounted on the drive guide rail, and a calibration plate connected below the slider and located above the rotating track.

[0006] Furthermore, the gear set is provided with a second rotating shaft connected to the output end of the drive motor. A first bevel gear is fixed on the second rotating shaft. The first bevel gear meshes with a second bevel gear. The second bevel gear meshes with a rotating gear. The rotating track is coaxially and fixedly connected to the rotating gear.

[0007] Furthermore, the conveying structure is also provided with a support plate, which is located above the rotating drum. An upwardly extending guide shaft is fixed at the center of the support plate, and the inner side of the rotating track cooperates with the guide shaft.

[0008] Furthermore, the rotating track is a synchronous belt with teeth on the inner side, and the rotating wheel cylinder has a groove with gears on the outer side of the middle part. The rotating track and the rotating wheel cylinder achieve meshing transmission through the gears in the grooves.

[0009] Furthermore, the drive guide rail of the calibration structure is provided with a stator, and a mover is provided opposite to the stator, the mover being connected to the slider.

[0010] Furthermore, support seats are provided on both sides of the rotating wheel cylinder, and the support shaft of the gear set and the support plate of the conveying structure are fixed to the support seats or the base plate extending therefrom.

[0011] This utility model has the following beneficial effects: (1) This utility model drives the first rotating shaft and the rotating track by a drive motor, and drives the rotating wheel to rotate smoothly by mechanical meshing. Then, the scraping groove on its inner side gently scrapes the nut and guides it into the nut holder of the rotating track. The whole process replaces the high-frequency and violent vibration and throwing of the traditional vibratory plate with continuous and stable rotational motion, so that the nut is always restricted in the holder and transported in an orderly manner, avoiding collisions and friction between nuts and between nuts and equipment.

[0012] (2) This utility model achieves an active grasping and positioning orientation mechanism by cooperating the scraping groove on the rotating wheel and the nut holder of a specific shape on the rotating track. Each scraping groove can only pick up a limited number of nuts during rotation and guide them into the nut holder at the junction point. The structural design of the holder only allows nuts with the correct posture to be stably accommodated.

[0013] (3) This utility model uses a linear motor composed of a stator and a mover as the driving source to directly control the slider and the calibration plate to make high-precision linear reciprocating motion on the drive guide rail. This structure allows the position, stroke and speed of the calibration action to be precisely controlled by the program.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 As shown, this utility model is a forming nut conveying device, including a rotating structure 1, a drive motor 11, a first rotating shaft 12 connected to the drive motor 11, a rotating track 13 connected to the first rotating shaft 12, a rotating wheel 14 meshing with the rotating track 13, and a plurality of arrayed scraping grooves 15 provided on the inner circumference of the rotating wheel 14. The rotating structure 1 is also provided with a conveying structure 2. The conveying structure 2 is provided with a gear set driven by a drive motor 11. The gear set is connected to a rotating track 27. The rotating track 27 is arranged around the top and outside of the rotating cylinder 14, and multiple nut holders 28 are provided on the inner side of the rotating track 27 along its path. The rotating track 13 is a synchronous belt with teeth on the inner side, and the rotating wheel 14 has a groove with gears on the outer side of the middle part. The rotating track 13 and the rotating wheel 14 achieve meshing transmission through the gears in the grooves. Support seats 16 are provided on both sides of the rotating drum 14; When the drive motor 11 starts, it drives the first rotating shaft 12 connected to it to rotate. The first rotating shaft 12 drives the rotating track 13 to rotate. Since the rotating track 13 is a synchronous belt with teeth on the inner side, it meshes with the gear in the groove on the outer side of the middle part of the rotating wheel 14, thereby transmitting power to the rotating wheel 14, causing it to rotate under the support of the support seat 16. During this process, the scraping grooves 15 distributed in multiple arrays on the inner side of the circumference of the rotating wheel 14 rotate accordingly, continuously scraping the nuts from the material pile and conveying them upwards, and finally guiding the nuts into the nut holder 28 provided on the inner side of the rotating track 27 surrounding it. The front end of the rotating structure 1 is also provided with a calibration structure 3, the calibration structure 3 is provided with a drive rail 31, a slider 34 is slidably arranged on the drive rail 31, and a calibration plate 35 located above the rotating track 27 is connected below the slider 34. The drive guide rail 31 of the calibration structure 3 is provided with a stator 32, and the stator 32 is provided with a mover 33 facing each other. The mover 33 is connected to the slider 34. When the rotating track 27 carrying the nut runs to the bottom of the calibration structure 3, the stator 32 in the drive guide rail 31 is energized, driving the oppositely arranged mover 33 to produce precise linear motion. The mover 33 drives the slider 34 fixedly connected to it to slide smoothly along the drive guide rail 31, thereby driving the calibration plate 35 connected to the bottom of the slider 34 to perform precise and controllable reciprocating motion above the rotating track 27, to correct or remove the nut passing below it. The gear set is provided with a second rotating shaft 21 connected to the output end of the drive motor 11. A first bevel gear 22 is fixed on the second rotating shaft 21. The first bevel gear 22 meshes with a second bevel gear 23. The second bevel gear 23 meshes with a rotating gear 24. The rotating track 27 is coaxially and fixedly connected to the rotating gear 24. The conveying structure 2 is also provided with a support plate 25, which is located above the rotating drum 14. The center of the support plate 25 is fixed with an upwardly extending guide shaft 26, and the inner side of the rotating track 27 cooperates with the guide shaft 26. The support shaft of the gear set and the support plate 25 of the conveying structure 2 are both fixed to the support base 16 or the base plate extending therefrom. The drive motor 11 drives the second rotating shaft 21 to rotate through its output end. The first bevel gear 22 fixed on the shaft rotates accordingly and drives the second bevel gear 23 and the rotating gear 24 meshing with it through a meshing relationship. Finally, the power is transmitted to the rotating track 27, which is coaxially fixedly connected to the rotating gear 24, causing the track to rotate smoothly around the top and outside of the rotating cylinder 14. During this process, the inner side of the rotating track 27 always cooperates with the guide shaft 26 fixed at the center of the support plate 25, ensuring the accuracy and stability of its rotation trajectory. The support shaft of the entire gear set and the support plate 25 are firmly fixed to the support base 16 or its extended base plate, forming a rigid support foundation.

[0019] In use, the drive motor 11 starts, simultaneously driving the first rotating shaft 12 and the second rotating shaft 21 to rotate. The first rotating shaft 12 drives the rotating track 13 to rotate, which in turn drives the rotating wheel 14 to rotate around its support base 16 through meshing transmission. At this time, the scraping grooves 15 distributed in an array on the inner circumference of the rotating wheel 14 rotate accordingly, scraping the stacked nuts one by one and guiding them to the top. At the same time, the second rotating shaft 21 drives the first bevel gear 22 to rotate, and through its meshing transmission with the second bevel gear 23 and the rotating gear 24, it finally drives the rotating track 27, which is coaxially connected to the rotating gear 24, to rotate. Rotating smoothly around the guide shaft 26, when the nut holder 28 inside the rotating track 27 moves with the track to the junction area with the rotating drum 14, it receives the nut introduced by the scraping groove 15. The nut holder 28 carrying the nut continues to move forward with the rotating track 27. After passing under the calibration structure 3, if it is necessary to correct or remove the nut, the stator 32 in the drive guide 31 drives the mover 33, which drives the connected slider 34 and calibration plate 35 to perform precise reciprocating motion, and performs the corresponding operation on the nut passing below, thereby completing the fully automated, low-damage conveying and calibration of the nut.
