[0032] In use, the clamping structure 10 is located above the conveying belt on one side of the edge polishing machine body 1, the conveying belt conveys the workpiece into the clamping structure 10, then the sliding column 5 and the sliding block 8 are synchronously moved, the sliding block 8 can drive the workpiece to move horizontally through the vertical shaft 9 and the clamping structure 10, at the same time, the distance between the sliding column 5 and the sliding block 8 increases due to the inclined movement of the sliding column 5 along the guide groove 4, at this time, the sliding column 5 can drive the vertical shaft 9 to rotate through the first adjusting plate 6 and the second adjusting plate 7, the vertical shaft 9 drives the clamping structure 10 and the workpiece to rotate around the axis of the vertical shaft 9, so as to adjust the direction of the workpiece while conveying, the clamping structure 10 and the workpiece can be converted from the longitudinal direction to the transverse direction, so as to conveniently put the clamping structure 10 and the workpiece between the two polishing units in the edge polishing machine body 1 in the transverse direction, avoid the collision between the clamping structure 10 and the polishing units in the edge polishing machine body 1 or the hindering of the contact between the polishing units and the workpiece when the clamping structure 10 and the workpiece move horizontally, and facilitate the reversing feeding work of the workpiece, when the workpiece is processed, the workpiece on the edge polishing machine body 1 can be taken off through the other feeding mechanism 2, so as to realize the automatic feeding and discharging work of the edge polishing machine body 1.

[0034] Preferably, as shown in Figure 3 The platform 3 is composed of a first sub-plate 11 and a second sub-plate 12, both of which are provided with openings, and the two openings are connected to form a complete guide groove 4, the first sub-plate 11 and the second sub-plate 12 are connected by a plurality of insertion rods, the end of the second sub-plate 12 away from the first sub-plate 11 is provided with a limiting plate 13, and the second sub-plate 12 is connected with the first sub-plate 11 by a return plate spring 14.

[0035] Specifically, when the workpiece needs to be fed or unloaded, the clamping structure 10 on the two material conveying mechanisms 2 needs to be moved to the same position on the edge polishing machine body 1. In order to avoid interference between the two material conveying mechanisms 2 and to realize the feeding and unloading work, the structure of the first sub-plate 11 and the second sub-plate 12 is required, that is, when the sliding block 8 slides on the first sub-plate 11 to the second sub-plate 12, the sliding column 5 slides into the opening on the second sub-plate 12 from the opening on the first sub-plate 11, the sliding block 8 contacts the limiting plate 13, and the sliding block 8 pushes the second sub-plate 12 to move laterally through the limiting plate 13, so that the clamping structure 10 moves laterally to the feeding and unloading position of the edge polishing machine body 1, the return plate spring 14 is elastically deformed, and the insertion rod between the first sub-plate 11 and the second sub-plate 12 can guide the second sub-plate 12. When the feeding and unloading are completed, the sliding block 8 moves reversely, the second sub-plate 12 is reset by the return plate spring 14 and is butted with the first sub-plate 11, at this time the sliding block 8 can slide from the second sub-plate 12 to the first sub-plate 11, so as to realize the normal feeding and unloading work of the workpiece and avoid the interference between the two material conveying mechanisms 2.

[0036] The first sub-plate 11 is fixed in the horizontal position, and the second sub-plate 12 can move in the horizontal direction.

[0037] Preferably, as shown in Figures 2 to 4 The material conveying mechanism 2 further comprises a top plate 15, the top plate 15 is provided with a swing rod 16 which swings left and right, the bottom of the swing rod 16 is fixed horizontally with a push rod, the outer side of the push rod is vertically sleeved with a first long slot plate 17, and the push rod and the first long slot plate 17 slide relative to each other, the bottom of the first long slot plate 17 is provided with a sliding plate 18 which is slidingly installed on the bottom of the platform 3, the bottom of the sliding plate 18 is fixed with a second long slot plate 19 which is fixedly connected with the sliding block 8, and the sliding column 5 penetrates through the second long slot plate 19 and slides relative to it.

[0038] Specifically, the top plate 15 supports the swing lever 16, when the swing lever 16 swings, the swing lever 16 can push the first long slot plate 17 to move transversely, the first long slot plate 17 can push the sliding plate 18 to move transversely, the sliding plate 18 slides at the bottom of the platform 3, and the sliding plate 18 can push the sliding column 5 and the sliding block 8 to move transversely through the second long slot plate 19, so that the sliding column 5 slides in the guide groove 4, and the sliding block 8 moves transversely on the side wall of the platform 3, so as to realize the purpose of providing power for the sliding column 5 and the sliding block 8 synchronously, and because the guide groove 4 is inclined, the sliding column 5 slides in the second long slot plate 19.

[0039] Because the sliding column 5 and the sliding block 8 move synchronously through the second long slot plate 19, and the sliding column 5 and the sliding block 8 are connected through the vertical shaft 9, the second adjusting plate 7 and the first adjusting plate 6, the first adjusting plate 6 and the second adjusting plate 7 can deform in the shape of a triangle, so that the sliding column 5 and the sliding block 8 can realize the effect of self-positioning, that is, the sliding column 5 cannot rotate randomly in the guide groove 4, and the vertical shaft 9 cannot rotate randomly on the sliding block 8.

[0040] Preferably, as shown in Figure 2 and Figure 5 The top plate 15 is fixed with a fixed plate 20, and the fixed plate 20 is fixed with a motor 21, and the output end of the motor 21 is transmissionally provided with a rotating disc 22, and the end face wall of the rotating disc 22 is provided with an annular groove 23, wherein the annular groove 23 is composed of two arc-shaped parts and two inclined parts, the two ends of the arc-shaped part are respectively communicated with the two inclined parts, the center of the arc-shaped part coincides with the axis of the rotating disc 22, and the two arc-shaped parts are respectively a large radius arc-shaped part and a small radius arc-shaped part.

[0041] The annular groove 23 is slidably provided with a guide column 24, the guide column 24 is fixedly connected with the swing lever 16, and the axis of the guide column 24 is on the same horizontal plane as the axis of the rotating disc 22.

[0042] Specifically, the fixed plate 20 can support the motor 21, the motor 21 drives the rotating disc 22 to rotate, the rotating disc 22 moves relative to the guide column 24, so that the guide column 24 slides in the annular groove 23, when the guide column 24 slides in the large radius arc-shaped part of the annular groove 23, the swing lever 16 inclines away from the edge polishing machine body 1, at this time the sliding block 8 is away from the edge polishing machine body 1, when the guide column 24 slides from the large radius arc-shaped part to the small radius arc-shaped part through the inclined part, the swing lever 16 inclines towards the edge polishing machine body 1, at this time the clamping structure 10 and the workpiece move to the feeding and discharging position of the edge polishing machine body 1.

[0043] By providing two arc-shaped parts on the annular groove 23, the position of the sliding block 8 is fixed when the guide column 24 slides in the arc-shaped part, so as to provide enough time for the clamping and loosening work of the clamping structure 10, and the inclined part on the annular groove 23 can transition the two arc-shaped parts.

[0044] To ensure that the dwell time of slider 8 is consistent, turntable 22 rotates at a constant speed, and the arc angles of the two arc-shaped parts on the annular groove 23 are consistent.

[0045] As the swing arm 16 swings, the guide post 24 is displaced in the vertical direction. In order to avoid the guide post 24 getting stuck in the inclined part of the annular groove 23, the radius of the small-radius arc part of the annular groove 23 needs to be greater than the vertical distance between the axis of the guide post 24 and the axis of the turntable 22 when the swing arm 16 is vertical.

[0046] Preferred, such as Figure 2 As shown, a synchronous shaft 25 is fixed at the axis position of the end face wall of the turntable 22. A push plate 26 is provided on the synchronous shaft 25. The push plate 26 is elliptical in shape. A right-angle bracket 27 is provided in contact with the bottom of the push plate 26. The right-angle bracket 27 is vertically slidably installed on the top plate 15. A vertical rod 28 is fixed at the top of the right-angle bracket 27. The vertical rod 28 passes through the top plate 15 and is slidably connected to each other. A spring 29 is sleeved on the outside of the vertical rod 28. The top plate 15 and the right-angle bracket 27 are connected by the spring 29. A connecting plate 30 is fixed at the bottom of the right-angle bracket 27. The bottom of the connecting plate 30 is fixedly connected to the top of the first sub-plate 11.

[0047] Specifically, spring 29 generates an upward elastic pull on right-angle frame 27, thereby making right-angle frame 27 fit tightly against the bottom of push plate 26. When turntable 22 rotates, turntable 22 drives synchronous shaft 25 and push plate 26 to rotate synchronously. Since push plate 26 is elliptical in shape, push plate 26 can push right-angle frame 27 to move up and down. Right-angle frame 27 drives spring 29 to perform telescopic movement. Vertical rod 28 slides on top plate 15. At the same time, right-angle frame 27 can drive platform 3 to move up and down through connecting plate 30. When clamping structure 10 moves to the material picking position, it moves vertically downward and grabs the workpiece. Then clamping structure 10 and workpiece move to the initial height position. At this time, the workpiece is vertically away from the conveyor belt or prism polisher body 1, thereby avoiding collision with other objects when clamping structure 10 and workpiece move horizontally. When clamping structure 10 moves to the material unloading position, clamping structure 10 and workpiece move down again, thereby placing the workpiece on prism polisher body 1 or conveyor belt.

[0048] By adopting this structure, the movement trajectory of the clamping structure 10 can be bow-shaped with the bow-shaped opening facing downwards.

[0049] Preferred, such as Figures 6 to 7As shown, the push plate 26 is composed of two first splicing plates 31 distributed in front and back and two second splicing plates 32 distributed in up and down, the first splicing plate 31 is fixed on the synchronous shaft 25, the second splicing plate 32 is slidingly installed between the two first splicing plates 31, the end of the second splicing plate 32 is a semicircular surface, and thus the two first splicing plates 31 and the two second splicing plates 32 form an ellipse.

[0050] Specifically, by making the two first splicing plates 31 and the two second splicing plates 32 form the push plate 26, when the position of the second splicing plate 32 on the first splicing plate 31 is adjusted, the length of the ellipse can be adjusted, so that the up and down moving distance of the right angle frame 27 is adjusted, and the up and down moving distance of the platform 3, the clamping structure 10 and the workpiece is adjusted.

[0051] Preferably, as shown in the figure, Figure 7 As shown, a slot is formed in the middle of the synchronous shaft 25 and penetrates up and down, the length direction of the slot is along the axis direction of the synchronous shaft 25, a threaded rod 33 is rotatably arranged in the slot, a threaded sleeve 34 is screwed on the threaded rod 33, a third adjusting plate 35 is obliquely rotatably arranged on the upper and lower sides of the threaded sleeve 34, the third adjusting plate 35 is rotatably connected with the second splicing plate 32, the end of the threaded rod 33 extends to the outside of the synchronous shaft 25, and a lock nut 36 is arranged between the threaded rod 33 and the synchronous shaft 25.

[0052] Specifically, by the lock nut 36, the threaded rod 33 can be locked and fixed on the synchronous shaft 25, when it is necessary to adjust the position of the second splicing plate 32 on the first splicing plate 31, the lock nut 36 is loosened and the threaded rod 33 is rotated, the threaded rod 33 can push the threaded sleeve 34 to move, and the threaded sleeve 34 can push the second splicing plate 32 to slide on the first splicing plate 31 through the third adjusting plate 35.

[0053] Preferably, as shown in the figure, Figure 4 As shown, the clamping structure 10 includes an arc-shaped frame 37 with an opening facing downward, a fixing groove is formed on the front and rear side walls of the arc-shaped frame 37, two cams 38 are rotatably arranged in the fixing groove, the cams 38 are inclined and the directions of the two cams 38 are opposite, the side of the cam 38 away from the axis thereof extends into the arc-shaped frame 37, and a tooth is arranged on the arc-shaped outer wall of the cam 38 close to the axis thereof, the two cams 38 are meshed with each other through the teeth.

[0054] The top of the arc-shaped frame 37 is provided with a gas cylinder 39, a fourth adjusting plate 40 is slidingly arranged in the arc-shaped frame 37 in the vertical direction, the extending end of the gas cylinder 39 is connected with the fourth adjusting plate 40, and two fifth adjusting plates 41 are obliquely rotatably arranged on the bottom of the fourth adjusting plate 40, the fifth adjusting plate 41 is rotatably connected with one of the cams 38 in the fixing groove.

[0055] Specifically, when the air cylinder 39 extends and retracts, the air cylinder 39 can push a cam 38 in the fixed slot to rotate through the fourth adjusting plate 40 and the fifth adjusting plate 41. Since the two cams 38 are engaged with each other, the two cams 38 in the fixed slot rotate synchronously and reversely. The side of the cam 38 away from the axis line contacts and extrudes the workpiece to fix the workpiece, so as to fix the workpiece on the clamping structure 10.

[0056] By synchronously and reversely rotating the two cams 38 in the fixed slot, the two cams 38 can generate extrusion forces on the workpiece in the inclined downward and inclined upward directions. The separation of the inclined forces in the vertical direction is offset, and the friction force generated on the workpiece by the inclined forces can further enhance the fastening strength of the workpiece in the vertical direction.
