Description

Technical Field

[0001] The invention relates to a processing system, in particular to a processing system for roughening a steering wheel. Background Art

[0002] With the vigorous development of my country's automobile industry and people's pursuit of automobile safety, aesthetics and comfort, the processing requirements for automobile internal parts are becoming more and more stringent. The core function of the steering wheel is to accurately control the direction of the car, so it needs to be used frequently by the driver. In order to improve the comfort and aesthetics of the steering wheel, it is necessary to wrap leather on the foam layer of the steering wheel and roughen the steering wheel to enhance the bonding effect between the leather and the foam layer of the steering wheel. The traditional technical solution uses the method of manually roughening the steering wheel, which has a low overall automation level, low processing efficiency (120s / pcs), high labor costs, and more importantly, poor consistency of the roughening effect. Summary of the invention

[0003] Based on this, it is necessary to provide a processing system for roughening a steering wheel in view of the deficiencies in the prior art.

[0004] A processing system for roughening a steering wheel comprises a conveying system, several manipulators, a trimming system, a grinding system, a roughening system and a system controller, wherein the system controller controls the conveying system, the manipulators, the trimming system, the grinding system and the roughening system to work. A carrier is provided on the conveying system, and the carrier is used to carry the steering wheel and assist in orienting the steering wheel. The conveying system delivers the steering wheel forward so that the steering wheel is transferred to different workstations. The manipulators are used to transfer the steering wheel to the conveying system and to the processing workstations corresponding to the trimming system, the grinding system and the roughening system. The trimming system, the grinding system and the roughening system perform trimming, grinding and roughening on the steering wheel respectively.

[0005] In one embodiment, the edge trimming system includes a tool and a laser system, and the tool and the laser system are used for rough edge trimming and fine edge trimming of the steering wheel respectively.

[0006] In one of the embodiments, the laser system is provided with a laser galvanometer for adjusting the cutting path of the laser system. When performing the rough edge trimming process, the robot transfers the steering wheel to the processing station of the tool, and the robot drives the steering wheel to rotate. During the rotation process, the tool performs preliminary cutting of the waste edges on the steering wheel.

[0007] In one of the embodiments, it also includes a CCD imaging system. When performing the fine edge trimming process, the robot transfers the steering wheel to the processing station of the laser system, and the robot drives the steering wheel to rotate. The CCD imaging system obtains the image of the steering wheel in the vertical direction. The system controller stitches multiple steering wheel images into a complete product image, and compares it with the standard image of the steering wheel to confirm the excess waste edge area. The system controller controls the laser system to perform fine edge trimming on the steering wheel.

[0008] In one of the embodiments, the grinding system includes two positioning seats arranged opposite to each other in an upper and lower direction, a first drive motor connected to one of the positioning seats, a drive cylinder connected to the other positioning seat, a positioning device, a second drive motor installed on the positioning device, and a grinding head connected to the second drive motor. The grinding head is arranged at one side of the positioning seat, the positioning device adjusts the position of the grinding head in the X and Y axis directions, and the driving cylinder drives the positioning seat connected thereto to adjust the position in the Z axis direction. During grinding, the manipulator places the steering wheel to be polished between the two positioning seats, and the driving cylinder drives the positioning seat connected thereto to press down so that the steering wheel to be polished is clamped between the two positioning seats. The first driving motor drives the steering wheel to be polished to rotate intermittently, and the second driving motor drives the grinding head to rotate. The positioning device drives the grinding head to approach the steering wheel, so that the rotating grinding head grinds the steering wheel.

[0009] In one embodiment, the roughening system includes a laser system and an infrared laser galvanometer scanning system. The infrared laser galvanometer scanning system is used to adjust the light output angle of the laser system, so that the laser system can process micro-groove lines extending in a linear direction on the steering wheel. During processing, the robot transfers the steering wheel to be roughened to the processing station of the roughening system, and the robot drives the steering wheel to be roughened to rotate intermittently. The laser system processes regularly or irregularly distributed micro-groove lines on the steering wheel according to the marking card.

[0010] In one embodiment, the manipulator is a six-axis robot.

[0011] The beneficial effect of the processing system for roughening the steering wheel of the present invention is that: by setting a conveying system, a manipulator, an edge trimming system, a grinding system, a roughening system and a system controller, the system controller controls the conveying system, the manipulator, the edge trimming system, the grinding system and the roughening system to work.

[0021] See also Figures 1 to 3 The present invention provides a processing system for achieving roughening of a steering wheel, which is used to process a steering wheel 100 product after mold forming. The processing of the steering wheel 100 product includes a trimming process, a grinding process, and a roughening process. The trimming process is used to cut off the waste edge 101 on the steering wheel 100, and the trimming process includes a rough trimming process and a fine trimming process. The grinding process is used to grind the parting line 102 of the steering wheel 100, so that the surface at the position of the parting line 102 forms a roughened polished surface 103, and realizes the arc transition at the position of the parting line 102. The parting line 102 is located on the outer peripheral surface between the front and back sides of the steering wheel 100. The roughening process is used to roughen the front and back sides of the steering wheel 100, so that the outer surface of the front or back side of the steering wheel 100 forms regularly distributed micro-groove lines 104. The front side of the steering wheel 100 is the side that the driver faces directly, and vice versa, it is the back side.

[0022] The processing system for roughening the steering wheel includes a conveying system 10, several manipulators 20, a trimming system 30, a grinding system 40, a roughening system 50 and a system controller 60, wherein the system controller 60 controls the conveying system 10, the manipulators 20, the trimming system 30, the grinding system 40 and the roughening system 50 to work. The conveying system 10 is provided with a carrier (not shown in the figure), which is used to carry the steering wheel 100 and assist in the orientation of the steering wheel 100. The conveying system 10 delivers the steering wheel 100 forward so that the steering wheel 100 is transferred to different workstations. The manipulators 20 are used to transfer the steering wheel 100 to the conveying system 10 and to the processing stations corresponding to the trimming system 30, the grinding system 40 and the roughening system 50. Among them, the manipulator 20 is a six-axis robot. The trimming system 30, the grinding system 40 and the roughening system 50 perform trimming, grinding and roughening treatments on the steering wheel 100 respectively.

[0023] The trimming system 30 includes a tool 32, a laser system 31 and a CCD imaging system 33. The tool 32 and the laser system 31 are respectively used for rough trimming and fine trimming of the steering wheel 100. The laser system 31 is provided with a laser galvanometer 311 for adjusting the cutting path of the laser system 31. When performing the rough trimming process, the robot 20 transfers the steering wheel 100 to the processing station of the tool 32, and the robot 20 drives the steering wheel 100 to rotate. During the rotation process, the tool 32 performs preliminary cutting on the waste edge 101 on the steering wheel 100.

[0024] After completing the rough trimming process, the robot 20 transfers the steering wheel 100 to the processing station of the laser system 31, and the robot 20 drives the steering wheel 100 to rotate. The CCD imaging system 33 obtains the image of the steering wheel 100 in the vertical direction. The system controller 60 stitches multiple images of the steering wheel 100 into a complete product image, and compares it with the standard image of the steering wheel 100 to confirm the redundant waste edge 101 area. The system controller 60 controls the laser system 31 to perform fine trimming on the steering wheel 100. When performing fine trimming, the robot 20 adjusts the steering wheel 100, and combines with the laser galvanometer 311 on the laser system 31 to enable the laser system 31 to cut the waste edges 101 in different areas of the steering wheel 100. After completing the fine trimming, the robot 20 transfers the steering wheel 100 after the trimming process back to the conveying system 10, and the conveying system 10 transfers the steering wheel 100 after the trimming process to the next station.

[0025] The grinding system 40 includes two positioning seats 41 arranged opposite to each other in the upper and lower directions, a first driving motor 42 connected to one of the positioning seats 41, a driving cylinder 43 connected to the other positioning seat 41, a positioning device 44, a second driving motor 45 installed on the positioning device 44, and a grinding head 46 connected to the second driving motor 45. The grinding head 46 is arranged on one side of the positioning seat 41. The positioning device 44 adjusts the position of the grinding head 46 in the X and Y axis directions, and the driving cylinder 43 drives the positioning seat 41 connected thereto to adjust the position in the Z axis direction. The Z direction refers to the direction perpendicular to the horizontal plane; the X direction refers to the direction perpendicular to the friction force generated by the steering wheel 100 and the grinding head 46 when the steering wheel 100 rotates.

[0026] During grinding, the manipulator 20 places the steering wheel 100 to be grinded between the two positioning seats 41, and the driving cylinder 43 drives the positioning seat 41 connected thereto to press down, so that the steering wheel 100 to be grinded is clamped between the two positioning seats 41, and the first driving motor 42 drives the steering wheel 100 to be grinded to rotate intermittently, and the second driving motor 45 drives the grinding head 46 to rotate, and the positioning device 44 drives the grinding head 46 to approach the steering wheel 100, so that the rotating grinding head 46 grinds the steering wheel 100.

[0027] The roughening system 50 includes a laser system 51 and an infrared laser galvanometer scanning system 511. The infrared laser galvanometer scanning system 511 is used to adjust the light output angle of the laser system 51, so that the laser system 51 can process the micro groove lines 104 extending in the linear direction on the steering wheel 100. During processing, the manipulator 20 transfers the steering wheel 100 to be roughened to the processing station of the roughening system 50, and the manipulator 20 drives the steering wheel 100 to be roughened to rotate intermittently. The laser system 51 processes the micro groove lines 104 with regular or irregular distribution on the steering wheel 100 according to the marking card. After the steering wheel 100 is roughened, the manipulator 20 transfers the steering wheel 100 to the unloading position.
