Description

Technical Field

[0001] This utility model relates to the technical field of fastener pre-coating equipment, specifically to a feeding mechanism for microcapsule pre-coated fasteners. Background Technology

[0002] Chemical adhesives used on fasteners and screws are commonly referred to as fastening adhesives or anaerobic sealants. These adhesives are primarily used to ensure that screws do not loosen during operation. Current technology involves encapsulating reactive monomers in microcapsules, then formulating an anaerobic adhesive and pre-applying it to the threads of the fastener. When the fastener is tightened, the gap between the male and female threads shears and breaks down the microcapsules, allowing the reactive monomers to penetrate the gap adhesive and cure, achieving an anti-loosening and anti-leakage effect.

[0003] In the mass production of fastener pre-coating, a vibratory feeder and conveyor track are used to transport the fasteners to the pre-coating station, where microcapsule chemical adhesive is applied to the threaded surface of the fasteners. To prevent the fasteners from being tightly connected when they are transported to the pre-coating station, which could cause the volume of the fasteners to block the chemical adhesive pre-coating path and result in incomplete chemical adhesive coating on the fasteners.

[0004] The existing technology involves setting up two sets of cylinders on the conveying track. The piston rods of the two sets of cylinders are alternately inserted into the joints of the fasteners in the entire row, intercepting the second and subsequent fasteners on one side of the conveying direction, allowing the first fastener in the conveying direction to advance normally, creating space with the following fasteners. Then the piston rods alternate, and the second and subsequent fasteners advance a distance equal to the diameter of the fastener before being stopped again by the piston rods. At this point, the original second fastener becomes the first fastener. This cycle is repeated, allowing the fasteners that were originally lined up and output close together to be separated one by one, so that the chemical adhesive can be completely applied.

[0005] The existing technology has the following problems: the linkage control of the two sets of cylinders is prone to errors, which can lead to piston rod impact and damage to the fasteners. Moreover, the pre-coating of fasteners often changes in size and specifications, and the conveyor track and intercepting cylinder need to be prepared and replaced with appropriate accessories according to the changes in fastener size, resulting in additional equipment costs. The maintenance of complete disassembly and replacement is also time-consuming and labor-intensive.

[0006] Therefore, the feeding mechanism of pre-coated fasteners needs to be redesigned to make its interception more precise and adaptable to changes in fastener size, so as to facilitate mechanism adjustment and adaptation, rather than disassembling and replacing the entire fastener and preparing additional parts. Utility Model Content

[0007] To address the shortcomings of the aforementioned technologies, this invention provides a feeding mechanism for microcapsule pre-coated fasteners.

[0008] The technical solution of this utility model is as follows: A feeding mechanism for microcapsule pre-coated fasteners includes a feeding track, a base, a lifting slider, a drive motor assembly, a wheel, a connecting rod, a first intercepting rod, and a second intercepting rod. The feeding track is provided with a feeding groove adapted to the contour of the fastener, and the fastener moves in a row along the feeding groove. The base is provided with a sliding groove in the vertical direction, and the lifting slider is disposed in the sliding groove for sliding engagement. The lifting slider is provided with a first adjusting platform and a second adjusting platform on the vertically above and below the feeding track, respectively. Both the first adjusting platform and the second adjusting platform are provided with a first through-elongated oval groove parallel to the moving direction of the fastener.

[0009] Both the first and second intercepting rods include an insertion part and a connecting part. The connecting parts of the first and second intercepting rods are provided with connecting holes and are respectively connected to the first through-elongated groove of the first and second adjusting platforms by bolts and nuts. The spacing between the first and second intercepting rods is adapted to the diameter of the fastener and is spaced apart along the moving direction of the fastener.

[0010] The two ends of the connecting rod are respectively hinged to the wheel and the lifting slider. The drive motor unit rotates and links with the wheel, driving the lifting slider to slide up and down along the slide groove, causing the insertion parts of the first intercepting rod and the second intercepting rod to alternately insert into the gap between the diameter of the fastener and the adjacent fasteners on both sides of the moving direction, so as to feed the fasteners in the row one by one at intervals.

[0011] Further features of this invention: The feeding mechanism further includes a synchronizing ring, a first screw, a second screw, and an adjusting slider. The wheel is radially provided with an adjusting groove extending to the outer circumference of the wheel. The adjusting groove includes a first slot and a second slot extending to the outer circumference of the wheel, and a third slot facing the end face of the wheel. The adjusting slider is inserted into the adjusting groove for sliding engagement. The adjusting slider is provided with a hinge shaft connected to the connecting rod hinge along the axial direction of the wheel. The synchronizing ring is sleeved on the outer circumference of the wheel for coaxial fixation. The synchronizing ring is provided radially with a first threaded hole and a second threaded hole at the first slot and the second slot, respectively. The first screw and the second screw are threadedly engaged with the first threaded hole and the second threaded hole, respectively, and extend into the adjusting groove, abutting both ends of the adjusting slider in the sliding direction.

[0012] A further feature of this invention is that the connecting portion of the first and second intercepting rods is provided with a second through-elongated groove along the axial direction of the fastener. The insertion portion and the connecting portion are separately configured. The insertion portion includes a third screw and a pair of nuts. The insertion portion is slidably fitted in the second through-elongated groove. The pair of nuts are threadedly fixed to the third screw on both sides of the connecting portion.

[0013] Further features of this invention: The material conveying track includes an L-shaped base plate, a cap-shaped limiting plate, and a shaft support plate. The L-shaped base plate includes a vertical part and a horizontal part. The horizontal part is provided with a third through-elongated groove perpendicular to the moving direction of the fastener. The cap-shaped limiting plate and the shaft support plate are both vertically positioned on the end face of the horizontal part. The cap-shaped limiting plate and the shaft support plate are provided with threaded holes corresponding to the third through-elongated groove, and are slidably engaged with the third through-elongated groove by screws. The gap between the cap-shaped limiting plate and the vertical part is adapted to the axial thickness of the fastener nut. The distance between the shaft support plate and the cap-shaped limiting plate is adapted to the axial length of the fastener. The height of the cap-shaped limiting plate and the shaft support plate is adapted to the distance between the fastener and the horizontal part.

[0014] Further features of this invention: The vertical part is provided with a fourth through-elongated cylindrical groove along the vertical direction. The material conveying track also includes a height limiting plate. The height limiting plate is provided with a threaded hole corresponding to the fourth through-elongated cylindrical groove and is slidably engaged with the fourth through-elongated cylindrical groove by a screw. The distance between the height limiting plate and the horizontal part is adapted to the maximum radial dimension of the fastener. The shaft of the fastener passes through the gap between the height limiting plate and the cap limiting plate and extends toward the shaft support plate.

[0015] The beneficial effects of this utility model are as follows: First, by using a crank-connecting rod mechanism to drive the first and second intercepting rods on the lifting slider, which alternately insert into both sides of the fastener's moving direction, an integrated linkage scheme with the same power source is formed. Compared to the prior art where two sets of cylinders require program control and constant hardware adjustment and monitoring, the integrated linkage scheme of this application is simpler and more reliable, overcoming the problem of errors caused by alternating motion.

[0016] Second, the spacing between the first and second intercepting rods can be adjusted along the first and second through-elongated oval slots. A pair of nuts can also adjust the depth of the intercepting rods inserted into the gap between adjacent fasteners, allowing for convenient adaptation to different sizes and specifications of fasteners in different batches. By adjusting the axial length of the first and second screws within the adjustment groove, the position of the adjusting slider in the adjustment groove is controlled, thereby controlling the distance of the hinge shaft relative to the center of the wheel. This changes the eccentricity of the connecting rod relative to the center, thus adjusting the lifting amplitude of the lifting slider and the first and second intercepting rods.

[0017] Third, the material conveying track, through the adjustment structure of the height limiting plate, the cap limiting plate, and the shaft support plate, can adapt to the size changes of different parts of the fastener, always fit the fastener, and keep the fastener moving smoothly along the material conveying track.

[0029] The two ends of the connecting rod 25 are respectively hinged to the wheel 24 and the lifting slider 22.

The distance between the shaft support plate 13 and the cap limiting plate 12 is adapted to the axial length of the fastener 3.

[0035] The spacing between the first intercepting rod 26 and the second intercepting rod 27 can be adjusted along the first and second through-elongated cylindrical grooves 262. A pair of nuts can also be used to adjust the depth of the intercepting rods inserted between adjacent fasteners 3, allowing for convenient adaptation to different sizes and specifications of fasteners produced in different batches. By adjusting the axial length of the first screw 281 and the second screw 282 within the adjusting groove 241, the position of the adjusting slider 29 within the adjusting groove 241 can be controlled. This controls the distance of the hinge shaft 291 relative to the center of the wheel 24, changing the eccentricity of the connecting rod 25 relative to the center, thereby adjusting the lifting amplitude of the lifting slider 22 and the first and second intercepting rods 27.

[0036] The material conveying track 1, through the adjustment structure of the height limiting plate 14, the cap limiting plate 12, and the shaft support plate 13, can adapt to the size changes of different parts of the fastener 3, always fit the fastener 3, and keep the fastener 3 moving smoothly along the material conveying track 1.
