Description

Technical Field

[0001] This invention relates to the technical field of bumper unloading mechanisms, specifically to a part-removing device and method for producing thin-walled bumpers. Background Technology

[0002] The car bumper is undoubtedly one of the most important and easily damaged parts in the car body structure. During daily driving, the bumper is easily scratched and damaged due to various road conditions and unexpected situations, so it has become a part that is frequently involved in car repair.

[0003] However, during the production of car bumpers, industrial robots are needed to transfer the bumpers. When there is dust on the surface of the bumper, these tiny particles will fill the contact surface between the material and the suction cup, like an invisible barrier, which will seriously hinder the adsorption of the material. This will not only greatly reduce the firmness of the adsorption, but may also lead to the instability of the adsorption, thus bringing unnecessary trouble and safety hazards to the production process. Summary of the Invention

[0004] The purpose of this invention is to provide a part-removing device for the production of thin-walled bumpers, so as to overcome the above-mentioned defects in the prior art.

[0005] A part-retrieving device for producing thin-walled bumpers includes an industrial robot, a material-retrieving rack, an adsorption mechanism, and a cleaning mechanism. The industrial robot is located on top of the forming device, and its end effector is equipped with a material-retrieving rack. Adsorption mechanisms for adsorbing bumpers are respectively provided on both sides of the material-retrieving rack. The cleaning mechanism is located on the vacuum suction cup of the adsorption mechanism and blows air to clean the adsorption position of the vacuum suction cup on the bumper during the downward movement of the material-retrieving rack.

[0006] Preferably, the material handling rack includes a U-shaped frame, a mounting plate, and fixing rods. The two U-shaped frames are connected by a connecting rod. The mounting plate is located on the top of the U-shaped frame and has a quick-change disc connected to the end effector of the industrial robot. There are two fixing rods, which are symmetrically arranged on both sides of the U-shaped frame.

[0007] Preferably, the adsorption mechanism further includes a rotating frame, a spring, and a tightening screw. The rotating frame is rotatably connected to the fixed rod and abuts against the fixed rod through the tightening screw. The air vent of the vacuum suction cup is slidably connected to the rotating frame. The air vent of the vacuum suction cup is connected to the vacuum generator. The spring is fitted onto the air vent and located between the suction cup body of the vacuum suction cup and the rotating frame. A retaining ring is provided on the outside of the air vent on the upper side of the rotating frame.

[0008] Preferably, the cleaning mechanism includes a rigid air supply pipe, a telescopic air supply pipe, a fixed cylinder, and two springs. Several rigid air supply pipes are provided and rotatably connected to a support plate outside the retaining ring via a rotating shaft. A nozzle is provided at the lower end of the rigid air supply pipe. A torsion spring is sleeved on the rotating shaft. One end of the torsion spring is connected to the support plate, and the other end is connected to the rigid air supply pipe. The upper end of the rigid air supply pipe is connected to an air collection cylinder on the air vent of the vacuum suction cup via a telescopic air supply pipe. Two air collection cylinders on the same side are connected via a main air supply pipe. The fixed cylinder is located at the bottom of the connecting rod, and a sliding rod is slidably connected to its bottom. A piston is provided at one end of the sliding rod inside the fixed cylinder, and a pressure head is provided at the lower end of the sliding rod. Two springs are sleeved on the sliding rod and located between the pressure head and the fixed cylinder. The main air supply pipe is connected to the side of the fixed cylinder via a flexible air supply hose.

[0009] Preferably, a rubber pad is provided at the bottom of the pressure head.

[0010] Preferably, the two rotating frames are connected by an arc-shaped plate.

[0011] Preferably, the outer side of the arc-shaped plate is provided with a handle.

[0012] A method for removing parts used in the production of thin-walled bumpers includes the following steps:

[0013] Step 1: The industrial robot moves the material handling rack to directly above the bumper after it has been processed by the molding device, and moves the material handling rack down as well.

[0014] Step 2: When the top of the bumper contacts the pressure head at the bottom of the slide bar, it moves the slide bar upward. The gas in the fixed cylinder enters the gas collection cylinder on the air pipe of the vacuum suction cup through the air supply hose and the air supply main pipe, and is sprayed onto the bumper through the air supply telescopic pipe and the air supply hard pipe, so that the dust on its surface is blown away.

[0015] Step 3: When the material pick-up rack moves down to the position, the suction cup body of the vacuum suction cup contacts the bumper, and the spring on the air pipe of the vacuum suction cup is compressed. The air supply tube rotates adaptively under the action of the torsion spring on the rotating shaft, so that the suction cup body of the vacuum suction cup can better adsorb the bumper under the action of the vacuum generator.

[0016] Step 4: Finally, the bumper is transferred to the next workstation for processing using an industrial robot.

[0017] The present invention has the following advantages:

[0018] When the present invention is in use, when the sliding rod of the cleaning mechanism contacts the bumper, compressed air is sprayed onto the surface of the bumper through the nozzle to clean the dust on the bumper. The vacuum suction cup of the adsorption mechanism then adsorbs the bumper. During the adsorption process, the torsion spring on the rotating shaft allows the air supply tube to rotate adaptively. The whole process enables the vacuum suction cup to adsorb the bumper more smoothly. Attached Figure Description

[0028] It should be noted that the material handling rack 2 includes a U-shaped frame 21, a mounting plate 23, and a fixing rod 25. The two U-shaped frames 21 are connected by a connecting rod 22. The mounting plate 23 is located on the top of the U-shaped frame 21 and has a quick-change plate 24 on it for connection with the end effector of the industrial robot 1, which facilitates connection with the end effector of the industrial robot 1. There are two fixing rods 25, which are symmetrically arranged on both sides of the U-shaped frame 21.

[0029] In addition, the adsorption mechanism 3 also includes a rotating frame 31, a spring 35, and a tightening screw 32. The rotating frame 31 is rotatably connected to the fixed rod 25 and abuts against the fixed rod 25 through the tightening screw 32. The two rotating frames 31 are connected by an arc plate 33. A handle 331 is provided on the outer side of the arc plate 33, which facilitates the rotation of the rotating frame 31. The air pipe of the vacuum suction cup 34 is slidably connected to the rotating frame 31. The air pipe of the vacuum suction cup 34 is connected to the vacuum generator. The spring 35 is sleeved on the air pipe and located between the suction cup body of the vacuum suction cup 34 and the rotating frame 31. A retaining ring 36 is provided on the outer side of the air pipe on the upper side of the rotating frame 31.

[0030] Furthermore, the cleaning mechanism 4 includes an air supply rigid pipe 41, an air supply telescopic pipe 44, a fixed cylinder 47, and a spring 482. Several air supply rigid pipes 41 are provided and rotatably connected to a support plate 42 on the outside of the retaining ring 36 via a rotating shaft 411. A nozzle 412 is provided at the lower end of each air supply rigid pipe 41. A torsion spring 43 is sleeved on the rotating shaft 411. One end of the torsion spring 43 is connected to the support plate 42, and the other end is connected to the air supply rigid pipe 41. The upper end of the air supply rigid pipe 41 is connected to the vacuum suction cup 34 via the air supply telescopic pipe 44. The air collecting cylinder 45 is connected to the air pipe. The two air collecting cylinders 45 on the same side are connected by the air supply main pipe 46.

[0031] Detailed implementation methods and principles:

[0032] In practical application, the industrial robot 1 moves the material picker 2 to the top of the bumper after the molding device has finished processing, and moves the material picker 2 down. When the top of the bumper contacts the pressure head 481 at the bottom of the slide bar 48, the slide bar 48 moves up. The gas in the fixed cylinder 47 enters the gas collection cylinder 45 on the ventilation pipe of the vacuum suction cup 34 through the gas delivery hose 49 and the gas delivery main pipe 46, and is sprayed onto the bumper through the nozzle 412 via the gas delivery telescopic pipe 44 and the gas delivery hard pipe 41, so that the dust on its surface is blown away.

[0033] At the same time, when the material picker 2 moves down to its position, the suction cup body of the vacuum suction cup 34 contacts the bumper, and the spring 35 on the air pipe of the vacuum suction cup 34 is compressed. The air supply tube 41 rotates adaptively under the action of the torsion spring 43 on the rotating shaft 411, so that the suction cup body of the vacuum suction cup 34 can better adsorb the bumper under the action of the vacuum generator. Finally, the industrial robot 1 transfers the bumper to the next station for processing.

[0034] When the position of the vacuum suction cup 34 needs to be adjusted, loosen the tightening screw 32 on the rotating frame 31, drive the rotating frame 31 to rotate through the handle 331 on the arc plate 33, so that the vacuum suction cup 34 can be rotated to a suitable position, and then fix the rotating frame 31 to the fixing rod 25 through the tightening screw 32.

[0035] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner.
