Abstract

The invention discloses a material taking and feeding mechanism of blade forming equipment. The material taking and feeding mechanism comprises a mechanical arm and a material taking mechanism. And a fixing plate, a shell, a driving part, a shell, a pressure applying part and a material taking part are arranged in the material taking mechanism, and the shell is connected with the mechanical arm. And a mounting seat, a rotating seat and a pulling piece for connecting the mounting seat and the rotating seat are arranged in the visual identification assembly. According to the material taking and feeding mechanism of the blade forming equipment, reset rotation of the material taking piece is controlled through the elastic force of the second spring, and during rotation, the two clamping arms are kept close to the middle, so that the width of a clamping area is reduced. Due to the fact that the blade located in the clamping area is clamped through the elastic force of the second spring, the elastic force of the second spring does not deform the blade due to the large clamping force, the situation that the blade cannot be clamped due to the small clamping force is avoided, and damage to the surface of the blade is avoided. Multiple purposes are achieved, the clamping and transferring effect is improved, and meanwhile the quality of the blade is guaranteed.

[0052] The clamping arm 14 is arranged at the lower end of the rotating cylinder 35, and the clamping arm 14 is arranged in an arc shape and is arranged in a direction different from the direction of the guide groove 13. As shown in the figure, the direction of the guide groove 13 is in the M direction, and the direction of the clamping arm 14 is in the N direction. When the clamping arm 14 rotates, the clamping arm 14 will move closer to the quadrant point position, so as to keep the clamping area 15 reduced. Figure 17

[0053] One end of the second spring 16 forms a first retaining section 36, and the other end forms a second retaining section 37. The first cylinder 19 is provided with a first retaining hole 38 matched with the first retaining section 36, and the rotating cylinder 35 is provided with a second retaining hole 39 matched with the second retaining section 37. Through the limitation of the first retaining hole 38 and the second retaining hole 39, the position of the second spring 16 can be kept in a state of not moving. When the material taking piece 8 is rotated by a certain angle under the action of the pressing rod 12, it can be reset under the elastic force of the second spring 16.

[0054] The outer walls of the first cylinder 19 and the second cylinder 20 are each provided with a visual identification assembly 40. The visual identification assembly 40 is provided with a mounting seat 41, a rotating seat 42, and a pulling piece 43 for connecting the mounting seat 41 and the rotating seat 42. The mounting seat 41 is arranged on the outer wall of the first cylinder 19 and the second cylinder 20. The rotating seat 42 is hingedly connected to the mounting seat 41 through a hinge rod 44. The rotating seat 42 is provided with a positioning rod 45. One end of the pulling piece 43 is connected to the hinge rod 44, and the other end is connected to the positioning rod 45.

[0055] The mounting seat 41 is composed of a mounting plate 46 and a mounting body 47. The mounting body 47 has a retaining chamber 48 formed in the middle. The retaining chamber 48 is provided with a bearing protrusion 49. The mounting body 47 is provided with a hinge hole 50 matched with the hinge rod 44. The retaining chamber 48 is also provided with an elastic block 51. The elastic block 51 and the mounting plate 46 form an elastic gap 52. The elastic block 51 can be deformed under stress.

[0056] The rotating seat 42 is composed of a rotating part 53 and a mounting part 54. The inside of the rotating part 53 is hollow to form a first area 55. The inside of the mounting part 54 is hollow to form a second area 56. The first area 55 and the second area 56 are communicated, and the pulling piece 43 is located in the first area 55 and the second area 56.

[0057] ​The rotating portion 53 is provided with a strip-shaped hole 57 that mates with the hinge rod 44, allowing the hinge rod 44 to move relative to the strip-shaped hole 57. In practice, the strip-shaped hole 57 moves along with the rotating base 42. A camera 58 is mounted on the mounting portion 54. The width of the holding chamber 48 is smaller than the length of the rotating portion 53, and the depth of the holding chamber 48 matches the length of the rotating portion 53. The camera 58 can identify the blade on the conveyor belt. The conveyor belt structure is hollowed out in the middle, and the ends of the blade are placed on the conveyor belt, allowing the material 8 to be placed in the hollowed-out position to clamp the blade.

[0058] The pulling member 43 is composed of an elastic section 60 , a connecting section 61 , a first arc section 62 and a second arc section 63 . The first arc section 62 is connected to the hinge rod 44 , and the second arc section 63 is connected to the positioning rod 45 .

[0059] like Figure 21 As shown, by rotating the rotating seat 42, the position of the camera 58 can be changed, which is convenient for changing the lens or changing the position of the camera 58 when it is not needed, thereby better protecting the camera 58. After rotation, the pull member 43 is kept to pull the rotating portion 53 on the rotating seat 42 to be placed in the holding chamber 48 for limiting. When removing, it is only necessary to pull the rotating seat 42 first, and then rotate the rotating seat 42 so that the bearing protrusion 49 supports the rotating seat 42. When the rotating portion 53 is outside the holding chamber 48, the pull member 43 is in a stretched state, and when the rotating portion 53 is inside the holding chamber 48, the pull member 43 is in a natural state.

[0060] When clamping, it is only necessary to first push the pressure member 7 through the driver 5 so that the pressure rod 12 on the pressure member 7 moves downward, keep the guide groove 13 pushed, so that the material picking member 8 rotates, keep the clamping arm 14 and the clamping arm 14 rotating, and increase the clamping area 15. Then, it is placed in the hollow position in the middle of the conveyor belt, keep the camera 58 in the visual recognition component 40 to observe the blade situation, and take a photo of the blade to keep a record, and analyze whether the blade surface is damaged by the computer. After the blade arrives at the clamping opening 18, it will not move due to the certain position of the conveyor belt, so the height is consistent, which is convenient for the robot arm 1 to set the program and keep the robot arm 1 moving down to the specified position. When the clamping arm 14 reaches the specified height, the driver 5 drives the drive rod 9 to reset and the material picking member 8 can be reset under the elastic force of the second spring 16, thereby driving the material picking member 8 to rotate by the elastic force of the second spring 16 and clamping the blade by the clamping arm 14.
