DETAILED DESCRIPTION

[0021] The present invention can be further understood through the specific embodiments given below, but they are not intended to limit the present invention.

[0022] Embodiment 1: An automatic conveying mechanism for metal parts, comprising: a base plate 17 and a material conveying base 21 respectively mounted on the upper surface of the base plate 17, and a material picking bracket 4, wherein the material picking bracket 4 is arranged on one side of the front end of the material conveying base 21, and the front end and rear end of the material conveying base 21 are rotatably mounted with a front roller 221 and a rear roller 222, respectively, and any one of the front roller 221 and the rear roller 222 is drivingly connected to the output shaft of a motor 24, and a material conveying belt 23 is drivingly connected between the front roller 221 and the rear roller 222, and a plurality of the material sheets 100 are sequentially arranged on the upper surface of the material conveying belt 23 along the front-to-back direction and can move forward with the material conveying belt 23;

[0023] A strip block 18 is installed on the material conveying base 21 and above the front end of the material conveying belt 23. A feeding gap 19 is provided between the rear side surface of the strip block 18 extending perpendicularly to the length direction of the material conveying belt 23 and the frontmost sheet 100 arranged on the material conveying belt 23. A sensor 20 for sensing whether there is a sheet 100 in the feeding gap 19 is installed on the front side of the strip block 18. A cylinder 5 is installed on the material picking bracket 4. A movable block 6 is installed on the piston rod of the horizontally arranged cylinder 5. A vertically arranged clamping claw cylinder 7 is installed on the movable block 6. The first clamping portion 71 and the second clamping portion 72 of the clamping claw cylinder 7 can approach or move away from each other. When the piston rod of the cylinder 5 is in an extended state, the first clamping portion 71 and the second clamping portion 72 move horizontally to the feeding gap 19 or directly above the feeding gap 19.

[0024] When in use, first open the cover plate, arrange the materials to be transported on the upper surface of the conveyor belt in sequence, and then rotate the cover plate to a horizontal position. When the direction of the material is wrong, the cover plate cannot be rotated to a horizontal position. At this time, the position of the material with the wrong direction is corrected and adjusted until the cover plate can be rotated to a horizontal position, and the protrusions on each material piece are correspondingly embedded in the strip grooves on the lower surface of the cover plate, and then the motor is started to drive the conveyor belt to move. The conveyor belt drives the material piece forward until a feeding interval consistent with the thickness of a single material piece is formed between the material piece arranged at the front end and the rear side surface of the strip block, and the conveyor belt stops moving. In this process, each material piece is between the conveyor belt and the cover plate in the vertical direction, and between the two baffles in the left and right directions, thereby ensuring the relative position accuracy of the material piece during movement and realizing multi-dimensional protection of the material piece during transportation to avoid damage to the material piece during transportation.

[0036] A strip block 18 is installed on the material conveying base 21 and above the front end of the material conveying belt 23. A feeding gap 19 is provided between the rear side surface of the strip block 18 extending perpendicularly to the length direction of the material conveying belt 23 and the frontmost sheet 100 arranged on the material conveying belt 23.

The first clamping portion 71 and the second clamping portion 72 of the clamping claw cylinder 7 can approach or move away from each other. When the piston rod of the cylinder 5 is in an extended state, the first clamping portion 71 and the second clamping portion 72 move horizontally to the feeding gap 19 or directly above the feeding gap 19.

[0037] The first clamping part and the second clamping part of the clamping claw cylinder are placed in a loose state away from each other, and the L-shaped clamping blocks on the first clamping part and the second clamping part of the clamping claw cylinder are driven by the cylinder to move into the feeding interval, and then the material conveying belt is started to drive the sheet arranged at the front end to move forward to between the vertical parts of the two L-shaped clamping blocks;

[0038] The first clamping part and the second clamping part of the clamping claw cylinder are placed in a clamping state close to each other, so that the vertical parts of the two L-shaped clamping blocks are squeezed and contacted with the end faces at both ends of the sheet, thereby clamping the long strip of sheet, and then the clamping claw cylinder is driven to move by the cylinder to realize the transportation of the clamped sheet. The whole process is efficient and fast. The two L-shaped clamping blocks only need to move horizontally with the cylinder to cooperate with the material conveying belt to realize the one-by-one and continuous clamping and transportation of the sheet.

[0039] The sensor 20 is a contact sensor.

[0040] The first clamping part 71 and the second clamping part 72 are each installed with an L-shaped clamping block 8 on the opposite side of each other, and the horizontal part 11 of each of the two symmetrically arranged L-shaped clamping blocks 8 is installed on the first clamping part 71 or the second clamping part 72. When the first clamping part 71 and the second clamping part 72 of the clamping claw cylinder 7 move to the top of the feeding interval 19 and are close to each other, the vertical parts 12 of the two L-shaped clamping blocks 8 are in clamping contact with the end faces of the two ends of the material sheet 100 moved into the feeding interval 19.

[0041] A baffle 25 extending along the length direction of the conveying belt 23 is respectively installed on the above-mentioned conveying base 21 and located on both sides of the conveying belt 23, and the front end of each baffle 25 is located at the rear side of the feeding interval 19.

[0042] A cover plate 1 is rotatably mounted on the above-mentioned material transport base 21 and located on the outer side of any baffle 25. The front end of the cover plate 1 extending along the length direction of the material transport belt 23 is located on the rear side of the material replenishment interval 19. A strip groove 2 corresponding to the raised portion 101 on the material piece 100 is provided on the lower surface of the cover plate 1.

[0043] One side of the cover plate 1 is rotatably mounted on the material transport base 21 via a hinge assembly, and a handle portion 3 is mounted on the other side of the cover plate 1 .

[0044] The motor 25 is installed on the material conveying base 21 and is located below the material conveying belt 24 .

[0045] The surfaces of the vertical portions 12 of the two L-shaped clamping blocks 8 that are in contact with the sheet 100 are polyurethane surfaces, which can achieve stable clamping of the sheet and protect the end faces of both ends of the sheet from damage due to excessive force.

[0046] An elastic block 16 is installed on the vertical portion 12 of the above-mentioned two L-shaped clamping blocks 8.

[0047] The elastic block 16 is a rubber block.

[0048] When in use, first open the cover plate, arrange the materials to be transported on the upper surface of the conveying belt in sequence, and then rotate the cover plate to a horizontal position. When the direction of the materials is wrong, the cover plate cannot be rotated to the horizontal position. At this time, the position of the materials with the wrong direction is corrected and adjusted until the cover plate can be rotated to the horizontal position, and the protrusions on each material piece are correspondingly embedded in the strip grooves on the lower surface of the cover plate, and then the motor is started to drive the conveying belt to move. The conveying belt drives the materials forward until a feeding interval consistent with the thickness of a single material piece is formed between the material piece arranged at the front end and the rear side surface of the strip block, and the conveying belt stops moving. In this process, each material piece is between the conveying belt and the cover plate in the vertical direction and between the two baffles in the left and right directions, thereby ensuring the relative position accuracy of the materials during the movement process and realizing multi-dimensional protection of the materials during the transportation process to avoid damage to the materials during transportation.

[0049] Next, the first clamping part and the second clamping part of the clamping claw cylinder are placed in a loose state away from each other, and the L-shaped clamping blocks on the first clamping part and the second clamping part of the clamping claw cylinder are driven by the cylinder to move into the feeding interval, and then the material conveying belt is started to drive the sheet arranged at the front end to move forward between the vertical parts of the two L-shaped clamping blocks;

[0050] The first clamping part and the second clamping part of the clamping claw cylinder are placed in a clamping state close to each other, so that the vertical parts of the two L-shaped clamping blocks are squeezed and contacted with the end faces at both ends of the sheet, thereby clamping the long strip of sheet, and then the clamping claw cylinder is driven to move by the cylinder to realize the transportation of the clamped sheet. The whole process is efficient and fast. The two L-shaped clamping blocks only need to move horizontally with the cylinder to cooperate with the material conveying belt to realize the one-by-one and continuous clamping and transportation of the sheet.

[0051] When the automatic conveying mechanism of the metal parts is used, it can realize batch transportation of the sheets and can also clamp and carry the sheets one by one, and the operation is simple and efficient.
