DETAILED DESCRIPTION

[0027] Example 1: Reference Figure 1-Figure 5 A material taking device for automobile hinge welding comprises a frame 1 and a conveying seat 2. A baffle plate 4 is arranged at the rear end of the frame 1. The conveying seat 2 is fixed to the bottom of the frame 1. A hinge body 3 is conveyed on the conveying seat 2 at intervals. The hinge body 3 is provided with two rotating parts, one of which is horizontally placed on the conveying seat 2, and the other is arranged near the front end of the conveying seat 2. The bottom end of the baffle plate 4 slides with the top of the conveying seat 2. The width of the hinge body 3 is adapted to the width of the frame 1 on both sides of the baffle 4; a through slot 8 is provided on both sides of the frame 1, and the through slot 8 is located at the position of the baffle 4 close to the head end of the frame 1. A mounting box 9 is fixed at a position corresponding to the through slot 8 on the outer wall of the frame 1, and the mounting box 9 is opened toward the position of the through slot 8. A rotating shaft 10 is vertically rotated in the mounting box 9, and a motor 11 is connected to the bottom end of the rotating shaft 10. A positive material plate 12 corresponding to the position of the through slot 8 is fixed on the outer wall of the rotating shaft 10 The cam 12 is moved along the guide rail 11 and then moved back to the support rail 12. The cam 12 is moved along the guide rail 11 and then moved back to the support rail 12. The cam 12 is moved along the guide rail 11 and then moved back to the support rail 12.

[0028] In the present invention, reference is made to Figure 1-Figure 5The top of the frame 1 is fixed with a cover plate 13, and a gap is left between the outer wall of the top of the cover plate 13 and the top of the normally placed hinge body 3. A notch 14 is opened at the tail end of the frame 1, and the top and both sides of the notch 14 are open. When the hinge body 3 is placed normally, one of the rotating parts is horizontally placed on the conveying seat 2 and extends horizontally toward the two sides of the frame 1, and the other rotating part extends vertically upward and tilted toward the head end of the frame 1, and the bottom end of the rotating part rests on the conveying seat 2. At this time, a gap is left between the top of the hinge body 3 and the cover plate 13 to ensure the effective stability of the hinge body 3 as the conveying seat 2 moves forward. Due to the limitation of the conveying seat 2 at the bottom end, the other rotating part will not deflect downward, and the cover plate 13 is limited at the top end to prevent the other rotating part from deflecting upward, thereby further ensuring the stability of the hinge body 3 in the positive direction during the continuous conveying of the hinge, and ensuring the uniformity of each material taking to ensure the effectiveness of the entire manufacturing system.

[0029] In the present invention, reference is made to Figure 1-Figure 5 A movable cover 15 is slidably provided at the position of the notch 14. The length of the movable cover 15 is adapted to the length of the hinge body 3. The length of the notch 14 exceeds twice the length of the movable cover 15. A telescopic cylinder 16 is connected to the bottom end of one side of the movable cover 15. The telescopic cylinder 16 is fixed to the outer wall of the frame 1. The telescopic cylinder 16 can be used to move the movable cover 15 in the horizontal direction. When the conveying seat 2 moves to send the hinge body 3 to the tail end of the frame 1, the movable cover 15 is set at the position of the notch 14 near the head end. Figure 1 As shown, at this time, the baffle 4 is at a position where the movable cover 15 is close to the rear end of the frame 1, so that the top of the hinge body 3 sent to the position of the baffle 4 is limited by the top of the movable cover 15 to ensure the stability of the hinge body 3. After the hinge body 3 is sent to the baffle 4 and abuts against it, as shown in FIG. Figure 2 As shown, the movable cover 15 is moved to a position where the notch 14 is close to the rear end of the frame 1, so that the top and both sides of the hinge body 3 are exposed, so as to facilitate the manipulator to perform the material removal operation of the hinge body 3.

[0030] In the present invention, reference is made to Figure 1-Figure 5 Two fixing rods 5 are fixed at the position of the baffle 4 facing the rear end of the frame 1. A through hole is opened at the position of the rear end of the frame 1 corresponding to the fixing rod 5. The outer wall of the fixing rod 5 is slidably connected with the inner wall of the through hole. The fixing rod 5 is configured as a threaded rod at a position away from the baffle 4. The outer wall of the fixing rod 5 is threadedly connected with a fixing ring 6. The fixing ring 6 is configured at the outer end of the frame 1, so that the baffle 4 can be fixed by using the fixing rod 5 and the fixing ring 6, and the position of the baffle 4 can be adjusted.

[0031] In the present invention, reference is made to Figure 1-Figure 5An air duct 7 is connected to the top of the baffle 4, one end of the air duct 7 passes through the baffle 4 and is arranged toward the hinge body 3. A through hole is opened at the rear end of the frame 1 corresponding to the air duct 7, and the end of the air duct 7 is connected to a fan. When the hinge body 3 is transported to a position close to the baffle 4 and the material is taken, the air duct 7 is sucked toward the end position of the hinge body 3, and the other rotating part extending vertically in the hinge body 3 is slightly tilted toward the middle position to reduce the friction between the hinge body 3 and the conveying seat 2 and improve the convenience of taking materials.

The rollers 19 are arranged obliquely, and the length of the connecting shaft block 21 is smaller than the vertical width of the main material belt 20. Therefore, when using two rollers 19 and one connecting shaft block 21, the middle position of the main material belt 20 is arched toward the inner side of the frame 1, and the main material belt 20 is inclined on both sides of the connecting shaft block 21, so that the hinge body 3 moving toward the rear end of the frame 1 can be corrected, and the connecting shaft block 21 is only limited above the main material belt 20, so that the main material belt 20 is located below the connecting shaft block 21 and both sides are in a deformable state, so as to avoid hard squeezing of the hinge body 3 when the hinge body 3 is corrected by the positive material belt 20, so as to improve the protection effect of the hinge body 3 and improve the effectiveness of correcting the hinge body 3 during the movement.

[0033] In the present invention, reference is made to Figure 1-Figure 7 Air duct No. 23 is provided on both sides above the cover plate 13. One end of the air duct No. 23 is sealed and the other end of the air duct No. 23 is connected to an air pump. The bottom of the air duct No. 23 is connected to multiple connecting pipes 24 extending downward into the frame 1. The connecting pipes 24 blow air into the frame 1 at intervals. Through the multiple connecting pipes 24 distributed along the conveying seat 2, air is blown at intervals on both sides of the frame 1, so that the air pressure on the offset side of the hinge body 3 will be greater than the air pressure on the other side of the hinge body 3, so that the air blowing operation of the connecting pipes 24 cooperates with the positive material belt 20 to assist in straightening the offset hinge body 3, and some connecting pipes 24 blow air into the positive material belt 20, so that the positive material belt 20 is deformed at intervals to further improve the straightening operation effect on the hinge body 3.
