At this time, a leveling machine is needed to level and polish the surface of the flange blank. Especially for the seam flange, the surface of the seam flange usually has two gaps. When leveling the surface of this type of flange, special requirements are required for the placement angle of the flange in the leveling machine. The gap on the surface of the seam flange must be parallel to the feeding direction of the flange of the leveling machine, otherwise the flange will crack when the seam flange is processed and leveled.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1 As shown, a preferred embodiment of the utility model proposes a flange automatic seam-finding and pushing conveyor line, including a conveyor line body 1, a pushing mechanism 2, an end pushing mechanism 9, a visual detection mechanism 5 and other components, wherein a turntable 7 is also provided near the rear end of the conveyor line body 1 for adjusting the position of the flange, the end pushing mechanism 9 is provided on one side of the turntable 7, located at the discharging end of the conveyor line body 1, the pushing mechanism 2 is provided on one side of the conveyor line body 1, and can push the flange on the conveyor line body 1 onto the turntable 7, and the visual detection mechanism 5 is located directly above the turntable 7, for identifying the placement position of the flange on the turntable 7, and detecting whether the gap on the flange is in the set position.

[0030] like Figure 2 , Figure 3 As shown, the pushing mechanism 2 mainly includes components such as a truss 21, a slide plate 22, a driving assembly, a support plate 23, a bracket 24, a fixing seat 25 and a pushing piece 26, wherein the lower end of the truss 21 is fixed to one side of the conveyor line body 1, and the slide plate 22 is horizontally slidably connected to a slide rail arranged on the side of the truss 21 through a slider, and a mounting plate 28 is arranged on the top of the slide plate 22. The driving assembly consists of two parts, namely a driving motor 29 and a rack 30. The driving motor 29 is invertedly installed and fixed on the mounting plate 28. The output end of the driving motor 29 is connected to a gear, and the rack 30 is fixed to the top of the truss 21 and extends along the product conveying direction of the conveyor line body 1. The gear is meshed with the rack 30, and the gear is driven to rotate by the driving motor 29. With the cooperation of the rack 30, the slide plate 22 is driven to move horizontally along the truss 21.

[0031] The support plate 23 is horizontally fixed on the slide plate 22. Two brackets 24 are arranged on the support plate 23. The two brackets 24 are respectively located at the two ends of the support plate 23 and are perpendicular to the support plate 23. Two strip holes are opened on the bracket 24 for installing the fixing seat 25. The upper end of the pusher 26 is rotatably connected to the fixing seat 25.

[0032] like Figure 3 As shown, the top middle area of ​​the fixing seat 25 protrudes upward to form an insert portion 251, and the insert portion 251 is inserted into the strip hole and the top end is fixedly connected to the fixing plate 27. A plurality of linearly distributed bolt holes are provided on both sides of each strip hole, and the fixing plate 27 is fixedly connected to the bolt holes by bolts. The horizontal spacing between the two fixing seats 25 can be adjusted through the strip holes, thereby realizing the adjustment of the spacing between the two pushing members 26.

[0033] A U-shaped limiting groove is provided at the bottom of the fixed seat 25, so that the overall shape of the fixed seat 25 is "n"-shaped. A rotating shaft is arranged in the limiting groove, and the upper end of the pushing piece 26 is rotatably connected to the rotating shaft. A blocking and limiting mechanism 11 is provided on the side of the pushing piece 26 close to the incoming material direction of the conveyor line body 1, which is used to limit the rotation angle of the pushing piece 26, and a gap is left between the blocking and limiting mechanism 11 and the pushing piece 26.

[0034] refer to Figure 3 The blocking and limiting mechanism 11 is composed of a fixing block 111 and a limiting bolt 112, wherein the fixing block 111 is fixed to the side of the limiting groove, and the limiting bolt 112 is threadedly connected to the fixing block 111, one end of the limiting bolt 112 passes through the fixing block 111 and is inserted into the limiting groove, and a side of the pusher 26 close to the incoming direction of the conveyor line body 1 is provided with an avoidance slope. When the flange hits the pusher 26, the pusher 26 can be flipped upward at a small angle due to the existence of the avoidance slope.

[0035] Under the control of the driving assembly, the slide plate 22 moves with the pusher 26 toward the incoming direction of the conveyor line body 1. The pusher 26 hits the flange during the movement, and thus turns upward clockwise, so that the pusher 26 can smoothly pass over the flange. The pusher 26 moves from the left side of the flange to the right side, and then the pusher 26 returns to the initial position under the action of gravity.

[0036] Then the driving component controls the pushing piece 26 to move toward the discharge end of the conveyor line body 1, and the pushing piece 26 will push the flange to move toward the position of the turntable 7. During the process of pushing the flange, the pushing piece 26 will not rotate counterclockwise due to the obstruction of the limit bolt 112, so the flange can be pushed to move. The distance between the two pushing pieces 26 can be adjusted according to the different diameters of the flange.

[0037] After the flange reaches the turntable 7 , the visual inspection mechanism 5 will identify the outer shape features of the upper surface of the flange, find the location of the gap on the upper surface of the flange, and detect whether the gap is parallel to the conveying direction of the conveyor line body 1 .

[0038] like Figure 1 and Figure 8 As shown, a support frame 3 is provided on the conveyor line body 1, and the support frame 3 spans above the turntable 7. A shading plate 4 is provided at the bottom of the support frame 3, and a through hole is opened in the middle of the shading plate 4. In this embodiment, the visual detection mechanism 5 adopts a visual camera, which is installed and fixed on the side of the support frame 3, and the shooting end of the visual camera extends downward into the through hole. The through hole on the shading plate 4 can reduce the shooting range of the visual camera, so that the visual camera can accurately capture the appearance features on the flange.

[0039] When the visual camera does not recognize the gap on the upper surface of the flange, the turntable 7 will rotate, thereby driving the flange to rotate. After the visual camera captures the gap on the upper surface of the flange, the turntable 7 will stop rotating.

[0040] like Figure 7 As shown, a rotating bearing seat 10 and a rotating motor 6 are arranged at the bottom of the conveyor line body 1, wherein the rotating bearing seat 10 is installed and fixed on the conveyor line body 1, and the rotating motor 6 is drivingly connected to the rotating bearing seat 10, and can drive the rotating bearing seat 10 to rotate, and a plane bearing is arranged at the upper end of the rotating bearing seat 10 for supporting and fixing the turntable 7.

[0041] refer to Figure 4 Two transition plates 8 are also provided at the discharge end of the conveyor line body 1, which play the role of transition buffer, and one end of the transition plate 8 extends to the position of the turntable 7. After the turntable 7 adjusts the position of the flange, the pushing mechanism 2 will continue to push the flange backward to the transition plate 8.

[0042] The horizontal height of the upper surface of the transition load plate 8 does not exceed the horizontal height of the upper surface of the turntable 7 to ensure that the flange does not collide with the transition load plate 8 and can smoothly reach the transition load plate 8. Finally, the end push mechanism 9 pushes the flange on the transition load plate 8 into the leveling machine.

[0043] like Figure 5 , Figure 6As shown, the end pushing mechanism 9 is mainly composed of a pushing cylinder 91, a slide rail, a movable plate 93, a fixed seat 25 and a pushing block 94, wherein the pushing cylinder 91, the slide rail, the fixed seat 25 and the pushing block 94 are each provided with two, wherein the two slide rails are respectively arranged on both sides of the conveyor line body 1, and are horizontally slidably connected with the slide rail on the conveyor line body 1, and the sliding direction is consistent with the product conveying direction of the conveyor line body 1; the two pushing cylinders 91 are also respectively arranged on both sides of the conveyor line body 1, respectively corresponding to the two slide rails, the two ends of the movable plate 93 are respectively fixedly connected with the two slide rails through the connecting piece 92, and the output end of the pushing cylinder 91 is fixedly connected with the connecting piece 92, and the movable plate 93 is pushed to move by the pushing cylinder 91.

[0044] The structure of the fixed seat 25 is the same as that of the fixed seat 25 of the push mechanism. The middle area of ​​the push block 94 is rotatably connected to the fixed seat 25. There is an inclined surface on the side of the push block 94 close to the material incoming direction of the conveyor body 1. At the same time, the bottom of the push block 94 extends downward to the right side of the fixed seat 25 for a certain length, so that a right angle is formed at the lower end of the push block 94. In this way, the center of gravity of the push block 94 is relatively right, and the formed right angle can prevent the push block 94 from rotating clockwise. The upper ends of the two push blocks 94 pass upward between the two transition load plates 8, and the movable plate 93 is located below the transition load plate 8.

[0045] When the pushing mechanism 2 pushes the flange to the position of the transition load plate 8, the flange will hit the inclined surface of the pushing block 94, causing the pushing block 94 to rotate counterclockwise, so that the flange can smoothly reach the transition load plate 8. After the flange completely reaches the transition load plate 8, the pushing block 94 rotates clockwise to return to the initial position under the action of its own weight, and the downward extending part of the lower end of the pushing block 94 will be in close contact with the side of the fixed seat 25 or the movable plate 93, and the fixed seat 25 or the movable plate 93 will block the pushing block 94 to prevent the pushing block 94 from continuing to rotate clockwise, and then the pushing cylinder 91 controls the pushing block 94 to move, and the pushing block 94 pushes the flange to the leveling machine, and the surface of the flange is leveled by the leveling machine.

[0046] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
