[0022] like Figures 1 to 5As shown, the bending laser cutting linkage flexible production device described in the embodiment of the present invention comprises a pair of conveyor belts 1, on which a laser cutting component 11 and a bending component 12 are sequentially installed; a fixed plate 13 is fixedly connected between the conveyor belts 1; an organic arm 14 is rotatably connected in the fixed plate 13; a square plate 15 is fixedly connected to the end of the organic arm 14; a cylinder 16 is fixedly connected to the top of the square plate 15; a round rod 17 is fixedly connected to the output end of the cylinder 16; the round rod 17 is arranged to penetrate the square plate 15 and Sliding connection; a vacuum suction cup 18 is fixedly connected to the bottom of the round rod 17; the vacuum suction cup 18 is multi-hole; the top of the vacuum suction cup 18 is connected to a pipe 19; when working, the workpiece is usually placed on the conveyor belt 1 so that it passes through the laser cutting component 11 for cutting, and then when it leaves the laser cutting component 11, the machine arm 14 is controlled to rotate to move the square plate 15 to the conveyor belt 1, and then the cylinder 16 is started so that the cylinder 16 pushes the round rod 17 downward, and when the round rod 17 moves downward, it pushes the vacuum suction cup 18 to the workpiece The workpiece moves, at this time, the pipeline 19 is connected to the air pump to first evacuate the gas inside the vacuum suction cup 18. When the round rod 17 pushes the vacuum suction cup 18 and the workpiece contacts the vacuum suction cup 18, the workpiece will block the holes on the surface of the vacuum suction cup 18. At this time, the air pump is still evacuating the vacuum suction cup 18, and then a negative pressure will be formed inside the vacuum suction cup 18, and at the same time, the workpiece and the vacuum suction cup 18 will be tightly fitted to be sucked and fixed. Then the machine arm 14 is controlled to rotate to the conveyor belt 1 on the other side. When the workpiece arrives, the air pump can be stopped to unlock the workpiece and make it fall onto the conveyor belt 1. Then it will move with the conveyor belt 1 to the inside of the bending component 12, and it can be bent at this time, thereby speeding up the turnover speed of the workpiece and reducing the transportation time of the workpiece; by using the vacuum suction cup 18 to absorb the workpiece, the damage to the workpiece can be reduced when the workpiece is sucked and moved, so that it can achieve flexible contact to protect the workpiece, and at the same time, vacuum adsorption can speed up the fixation of the workpiece, thereby reducing the fixation adjustment during the transportation of the workpiece.

[0023] The bottom of the square plate 15 is fixedly connected with a fixing ring 2; the fixing ring 2 and the round rod 17 are correspondingly arranged and slidably connected; the side wall of the fixing ring 2 is hinged with a plurality of connecting rods 21; the end of the connecting rod 21 is hinged with a plurality of push rods 22; the push rod 22 and the vacuum suction cup 18 are slidably connected; when working, before the vacuum suction cup 18 is used to suck the workpiece, the angle at the connection between the connecting rod 21 and the fixing ring 2 will change when the round rod 17 moves downward, and the angle at the connection between the connecting rod 21 and the push rod 22 will change as the vacuum suction cup 18 moves downward. The degree of change, at this time, the connecting rod 21 will pull the push rod 22 to approach the vacuum suction cup 18, and at the same time, the end of the push rod 22 will contact the edge of the workpiece, so as to adjust the position of the workpiece to make it gradually approach the vacuum suction cup 18 group, and then the vacuum suction cup 18 will suck and move it after contacting the workpiece; by adding the push rod 22, the workpiece can be moved to the middle of the vacuum suction cup 18, thereby reducing the position deviation of the workpiece and increasing the contact between the vacuum suction cup 18 and the workpiece, thereby increasing the stability of the workpiece when it is sucked by the vacuum suction cup 18, thereby accelerating the transmission of the workpiece.

[0024] The bottom of the vacuum suction cup 18 is connected to a plurality of rubber suction cups 3; the inner wall of the rubber suction cup 3 is fixedly connected to a plurality of elastic blocks 31; during operation, when the vacuum suction cup 18 is used to contact the workpiece, the rubber suction cup 3 will first contact the workpiece, and as the distance between the workpiece and the vacuum suction cup 18 gradually decreases, the rubber suction cup 3 will be located between the workpiece and the vacuum suction cup 18, at which time the rubber suction cup 3 will gradually deform, and at the same time the elastic block 31 will also deform, thereby increasing the contact area between the rubber suction cup 3 and the workpiece; by adding the rubber suction cup 3 and the elastic block 31, the rubber suction cup 3 can preliminarily fix the workpiece when sucking the workpiece, and then the vacuum suction cup 18 will fix it after the internal pressure becomes negative, thereby accelerating the fixation of the workpiece, and at the same time the rubber suction cup 3 and the elastic block 31 are elastic, which can increase the contact area when fixing the workpiece, thereby increasing the stability during fixation.

[0025] A shovel plate 4 is fixedly connected to the inner wall of the push rod 22; the surface of the shovel plate 4 is set as an inclined surface; the shovel plate 4 and the push rod 22 are set correspondingly; during operation, when the push rod 22 is used to adjust the position of the workpiece, before the push rod 22 contacts the workpiece, the shovel plate 4 will first contact the workpiece, and at this time the shovel plate 4 will gradually lift the workpiece to reduce the friction between the workpiece and the conveyor belt 1, thereby speeding up the movement of the workpiece; by adding the shovel plate 4, the workpiece can be lifted when the push rod 22 moves the workpiece, thereby reducing the friction with the conveyor belt 1 during movement, thereby reducing the resistance of the workpiece during movement.

[0026] The surface of the shovel plate 4 is rotatably connected with a plurality of balls 5; the balls 5 and the shovel plate 4 are correspondingly arranged; during operation, when the shovel plate 4 lifts the workpiece, the workpiece will contact the balls 5, and the balls 5 will rotate at this time to reduce the friction between the workpiece and the shovel plate 4, so that the workpiece is lifted by the shovel plate 4 faster; by adding the balls 5, the speed at which the workpiece is lifted can be accelerated.

[0027] A circular plate 6 is fixedly connected to the inner wall of the pipe 19; a plurality of circular holes 61 are opened on the inner wall of the circular plate 6; during operation, when the vacuum suction cup 18 is used to suck and fix the workpiece, some impurities on the surface of the workpiece will move to the pipe 19 through the vacuum suction cup 18, and the circular plate 6 will block these impurities at this time, thereby reducing the impurities entering the air pump from the pipe 19; by adding the circular plate 6, the impurities can be blocked and the air pump can be protected.

[0028] A rubber pad 7 is fixedly connected to the inner wall of the push rod 22; the rubber pad 7 and the push rod 22 are correspondingly arranged; during operation, when the push rod 22 is used to push the workpiece, the rubber pad 7 will first contact the workpiece, which will increase the friction between the workpiece and the push rod 22, thereby increasing the thrust of the push rod 22 on the workpiece; by adding the rubber pad 7, the friction can be increased when the push rod 22 moves the workpiece, thereby reducing slippage.

[0029] Working principle: Usually, the workpiece is placed on the conveyor belt 1 first so that it passes through the laser cutting component 11 for cutting. Then, when it leaves the laser cutting component 11, the machine arm 14 is controlled to rotate to move the square plate 15 to the conveyor belt 1, and then the cylinder 16 is started so that the cylinder 16 pushes the round rod 17 downward. When the round rod 17 moves downward, it pushes the vacuum suction cup 18 to move toward the workpiece. At this time, the pipeline 19 is connected to the air pump to first evacuate the gas inside the vacuum suction cup 18. When the round rod 17 pushes the vacuum suction cup 18 to contact the workpiece, the vacuum suction cup 18 is blocked by the workpiece. At this time, the air pump is still evacuating the vacuum suction cup 18, and then a negative pressure is formed inside the vacuum suction cup 18, and at the same time, the workpiece and the vacuum suction cup are 18 fits tightly to absorb and fix, and then controls the arm 14 to rotate to the conveyor belt 1 on the other side. When the workpiece arrives, the air pump can be stopped to unlock the workpiece and make it fall onto the conveyor belt 1. Then it moves with the conveyor belt 1 to the inside of the bending assembly 12, at which time it can be bent, thereby speeding up the turnover of the workpiece and reducing the transportation time of the workpiece; before using the vacuum suction cup 18 to absorb the workpiece, when the round rod 17 moves downward, the angle of the connection between the connecting rod 21 and the fixing ring 2 will change, and as the vacuum suction cup 18 moves downward, the angle of the connection between the connecting rod 21 and the push rod 22 will change, and at this time the connecting rod 21 will pull the push rod 22 toward the vacuum suction cup 18 When the push rod 22 is used to adjust the position of the workpiece, the shovel plate 4 will contact the workpiece before the push rod 22 contacts the workpiece. The workpiece will be gradually lifted to reduce the friction between the workpiece and the conveyor belt 1, thereby speeding up the movement of the workpiece; when the shovel plate 4 lifts the workpiece, the ball 5 and the workpiece will contact the ball 5, and the ball 5 will rotate to reduce the friction between the workpiece and the shovel plate 4, so that it is lifted up faster by the shovel plate 4; when the vacuum suction cup 18 is used to absorb and fix the workpiece, some impurities on the surface of the workpiece will move to the pipe 19 through the vacuum suction cup 18, and the circular plate 6 will block these impurities at this time, thereby reducing the impurities entering the air pump from the pipe 19; when the push rod 22 is used to push the workpiece, the rubber pad 7 will first contact the workpiece, which will increase the friction between the workpiece and the push rod 22, thereby increasing the thrust of the push rod 22 on the workpiece.
