DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] The metal sheet automatic positioning detection and conveying device is composed of a material guide component, a conveying line, a material discharge component, and an angle detection component;

[0029] like Figure 1 , Figure 2 As shown, the material guide assembly includes a material box 2, the bottom of the material box 2 is a V-shaped structure, which is used to accurately fit the V-shaped structure of the metal angle plate. The material box 2 is tilted, and a material opening 21 aligned with the V-shaped bottom is opened on the sinking end surface of the material box 2, so that the metal angle plate can conduct toward the material opening 21;

[0030] A material-dispensing wheel 23 is rotatably installed at the material inlet 21, and a motor is connected to the shaft end of the material-dispensing wheel 23. The material-dispensing wheel 23 has a plurality of impellers, and the width of the impellers is reduced along the radial direction so that the profile of the impellers fits the V-shaped space of the metal angle plate. An auger 22 is rotatably installed at the upturned end of the material box 2, and the auger 22 points to the material inlet 21. The shaft end of the auger 22 is connected to the motor, and there is a gap between the outer profile of the auger 22 and the V-shaped bottom of the material box 2 to accommodate the metal angle plate.

[0031] The metal angle plate to be inspected is placed in the material box 2, and the motor is turned on to drive the auger 22 to rotate. The auger 22 transfers the metal angle plate toward the material port 21. At the same time, the rotation of the auger 22 has a material turning effect, so that the metal angle plate is as flat as possible against the V-shaped bottom of the material box 2 and is transferred toward the material port 21. The motor is turned on to drive the material wheel 23 to rotate, and the blades at the bottom of the material wheel 23 swing into the material box 2. Only the metal angle plate that is flat against the V-shaped bottom of the material box 2 can be discharged from the material port 21. The metal angle plate with misplaced shape will be pushed back into the material box 2 by the blades of the material wheel 23, ensuring that the metal angle plate discharged from the material port 21 keeps the corners arranged downward and is discharged.

[0032] like Figure 1 , Figure 2 As shown, the conveyor line includes a track plate 1, which is tilted and parallel to the material box 2. The center line of the track plate 1 is concave to form a cross-sectional profile consistent with the angle of the metal angle plate. The upturned end of the track plate 1 is aligned with the connecting material port 21. A plurality of rubber wheels 3 are arranged and rotatably arranged above the track plate 1. Both sides of the rubber wheels 3 have inclined surfaces for rolling the V-shaped surface of the metal angle plate. The spacing between adjacent rubber wheels 3 is less than the length of a single metal angle plate. The motor synchronously connects all rubber wheels 3 through a belt assembly.

[0033] The metal angle plate guided out from the material port 21 moves along the track plate 1, and the motor is turned on to drive all rubber wheels 3 to rotate synchronously. The rotating rubber wheels 3 roll the metal angle plate forward to keep the metal angle plate at a fixed moving speed. At the same time, the rubber wheels 3 press down the metal angle plate to prevent it from warping.

[0034] like Figure 3 , Figure 4As shown, the material dispersing assembly includes a pressing handle 43 and a stop handle 44, a bracket 4 is fixed at the lower end of the track plate 1, and a driving assembly includes a cylinder 41, which is vertically mounted on the surface of the bracket 4, and the pressing handle 43 and the stop handle 44 are located above the track plate 1 and are arranged in sequence along the conduction direction of the metal angle plate, the bottom of the pressing handle 43 is a rubber disc and the top is a slide bar, and the pressing handle 43 slides vertically with the bracket 4 through the slide bar, the bottom of the stop handle 44 is a hard pointed angle plate and the top is a slide bar, and the stop handle 44 slides vertically with the bracket 4 through the slide bar, and the spacing between the pressing handle 43 and the stop handle 44 is greater than the length of a single metal angle plate and less than the length of two metal angle plates, the pressing handle 43 and the stop handle 44 are fixed with symmetrical tooth plates 45, a transmission gear 46 is rotatably connected to the bracket 4, and the transmission gear 46 is synchronously meshed and connected to the two tooth plates 45, and the telescopic end at the bottom of the cylinder 41 is fixed with a connecting frame 42, and the connecting frame 42 is fixedly connected to the tooth plate 45 connected to the stop handle 44;

[0035] The controller controls the cylinder 41 to intermittently extend and retract, and the cylinder 41 drives the connecting frame 42 to drive the blocking handle 44 to descend. The top of the blocking handle 44 contacts the surface of the track plate 1. At this time, the pressing handle 43 is in an upward state, and the metal angle plates arranged on the surface of the track plate 1 are blocked by the blocking handle 44. The cylinder 41 drives the blocking handle 44 to move upward, and the pressing handle 43 is driven by the gear plate 45 and the transmission gear 46 to descend and squeeze the second-to-last metal angle plate. The blocking handle 44 releases the penultimate metal angle plate, and the metal angle plates can be released stably one by one by controlling the pressing handle 43 and the blocking handle 44 to rise and fall alternately.

[0036] like Figure 3 , Figure 4 As shown, the angle detection component includes a defective bucket 5 and a finished product bucket 6, which are arranged at the sinking end of the track plate 1, and the end surface profiles of the defective bucket 5 and the finished product bucket 6 are the same as the end surface profile of the track plate 1. The bottom of the finished product bucket 6 is fixed with an axle rod, and the axle rod is elastically rotatably connected to the track plate 1 through a torsion spring. The bottom of the defective bucket 5 is fixed with an axle tube, and the axle tube is elastically rotatably connected to the track plate 1 through a torsion spring. Stop bars 8 are fixed on the symmetrical sides of the defective bucket 5 and the finished product bucket 6, and the stop bars 8 are against the edge of the track plate 1 to make the defective bucket 5 and the finished product bucket 6 aligned with the track plate 1. Gears are fixed at the ends of the axle rod of the finished product bucket 6 and the ends of the axle tube of the defective bucket 5, and a connecting frame 42 extends to the top of the gear. The connecting frame 42 fixes two racks 47, and the two racks 47 are reversely meshed and connected to the two gears. A limit bar 7 is fixed at one end of the finished product bucket 6 close to the defective bucket 5, and a guide gap consistent with the cross section of the metal angle plate is formed between the limit bar 7 and the finished product bucket 6.

[0037] When the cylinder 41 contracts and drives the connecting frame 42 upward, the rack 47 rises and disengages from the gear, and the elastic force causes the defective bucket 5 and the finished product bucket 6 to be aligned with the track plate 1. At this time, the metal angle plate released by the stop handle 44 slides to the surface of the defective bucket 5. If the bending angle of the metal angle plate is qualified, it can pass through the material guide gap and slide to the surface of the finished product bucket 6. If there is a deviation in the bending angle of the metal angle plate, it will be blocked by the limit bar 7 and retained in the defective bucket 5. When the cylinder 41 extends and drives the connecting frame 42 to descend, the rack 47 descends and drives the two gears to rotate in the opposite direction, so that the defective bucket 5 and the finished product bucket 6 are flipped in the opposite direction to discharge the metal angle plate to the side. At this time, the pressing handle 43 and the stop handle 44 switch positions up and down to wait for the next metal angle plate to be discharged, thereby realizing the efficiency of detecting the angles of the metal angle plates one by one and classifying and discharging them.

[0038] The flipping angles of the defective product bucket 5 and the finished product bucket 6 are 100° to 180°, ensuring that the metal angle plates in the defective product bucket 5 and the finished product bucket 6 can be discharged at an angle.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
