[0029] like Figure 2 , 3 As shown, the first conveying and transfer component 2 is used to convey a cassette filled with an in-vehicle LCD. After the in-vehicle LCD in the cassette is removed by the multi-axis robot 3, the cassette is controlled to descend and the empty cassette is discharged. The second conveying and transfer component 6 is used to convey an empty cassette. After the empty cassette is filled with an in-vehicle LCD by the multi-axis robot 3, the cassette filled with an in-vehicle LCD is controlled to descend and the cassette filled with an in-vehicle LCD is discharged.
[0030] Specifically, both the first conveying and transfer assembly 2 and the second conveying and transfer assembly 6 include a connecting side plate 21, a lifting platform 22, an upper conveyor line 23, and a lower conveyor line 24. The connecting side plate 21 is connected to the machine base 1, the lifting platform 22 is mounted on the connecting side plate 21, one end of the upper conveyor line 23 is fixedly connected to the connecting side plate 21, and the lower conveyor line 24 is located below the upper conveyor line 23 and is directly fixedly connected to the machine base 1.
[0031] The upper end of the elevator 22 is provided with a retainer plate 231. The retainer plate 231 (with a retainer or an empty retainer filled with an in-vehicle LCD) is moved up and down by the elevator 22. A gap is reserved between the lower line 24 and the elevator 22 for the retainer plate 231 to move.
[0032] Both the first conveying and transfer assembly 2 and the second conveying and transfer assembly 6 further include a side positioning mechanism and a clamping mechanism 232. The side positioning mechanism and the clamping mechanism 232 are both disposed on the upper line body 23. The side positioning mechanism and the clamping mechanism 232 cooperate to clamp the plug.
[0033] The side positioning mechanism includes a first positioning cylinder 2311 and a side positioning plate 2312. The cylinder body of the first positioning cylinder 2311 is connected to the upper line body 23, and the side positioning plate 2312 is connected to the cylinder column of the first positioning cylinder 2311. The side positioning plate 2312 is driven to move by the first positioning cylinder 2311 to clamp and position the long side of the plug.
[0034] The clamping mechanism 232 includes a positioning clamping plate 2321 and a second positioning cylinder 2322. The cylinder of the second positioning cylinder 2322 is connected to the positioning clamping plate 2321. The positioning clamping plate 2321 is rotated and clamped by the second positioning cylinder 2322 to clamp and position the short side of the plug.
[0035] It should be noted that the second positioning cylinder 2322 is clamped during rotation, and is therefore a rotary clamping cylinder.
[0036] Both the first conveying and transferring component 2 and the second conveying and transferring component 6 further include a horizontal transplanting mechanism. The horizontal transplanting mechanism includes a lead screw nut 251, a nut connecting plate 252, and a lead screw 253. The two ends of the lead screw 253 are rotatably connected to the upper layer line body 23 and driven by a motor. The lead screw nut 251 is sleeved on the lead screw 253 and threadedly connected to it. The lead screw nut 251 is also connected to the nut connecting plate 252 and is located in the middle position. The nut connecting plate 252 is connected to the cylinder body of the second positioning cylinder 2322 of the clamping mechanism 232. The horizontal transplanting mechanism drives the clamping mechanism 232 to move to different positions to achieve clamping and positioning of corresponding plugs of different sizes.
[0037] It should be noted that when the AGV transports a card filled with vehicle-mounted LCDs, it enters from the upper line 23 of the first conveyor transfer component 2 and flows to the elevator 22. The side positioning mechanism and clamping mechanism 232 clamp the card, and the multi-axis robot 3 removes the vehicle-mounted LCD from the card. After removal, the elevator 22 descends to the lower line 24 and discharges the empty card from the lower line 24, which is then transported to the warehouse by the AGV. When the AGV transports an empty card, it enters from the upper line 23 of the second conveyor transfer component 6 and flows to the elevator 22. The side positioning mechanism and clamping mechanism 232 clamp the card, and the multi-axis robot 3 places the vehicle-mounted LCD into the card. After filling, the elevator 22 descends to the lower line 24 and discharges the card filled with vehicle-mounted LCDs from the lower line 24, which is then transported to the warehouse by the AGV.
[0038] like Figure 4As shown, in this embodiment, the multi-axis robot 3 is used to remove or install the vehicle-mounted LCD from the jammed container, and to photograph and calibrate the coordinates of the jammed container. The multi-axis robot 3 includes a base 31, a robot body 32, a jammed container CCD camera 33, a fixture changing mechanism, and an LCD fixture 35. The base 31 is mounted on the machine tool 1, and the robot body 32 is connected to the base 31. The jammed container CCD camera 33 and the fixture changing mechanism are both located at the end of the robot body 32, and the LCD fixture 35 is connected to the end of the robot body 32 through the fixture changing mechanism. The jammed container CCD camera 33 is used to photograph and calibrate the coordinates of the jammed container, and the fixture changing mechanism is used to replace the LCD fixture 35 from the fixture library assembly 5.
[0039] The clamp replacement mechanism includes a clamp loading / unloading part 36 and a clamp body 37. The LCD clamp 35 is connected to the clamp loading / unloading part 36, and the clamp body 37 is connected to the clamp loading / unloading part 36 when ventilated by an air expansion structure. When replacing the LCD clamp 35, the clamp body 37 is de-ventilated under external control, the clamp loading / unloading part 36 is released, and the LCD clamp 35 is placed together in the corresponding clamp placement slot 51. Then, it is moved to the position of another spare LCD clamp 52, the clamp loading / unloading part 36 of the other spare LCD clamp 52 is aligned, the clamp body 37 is ventilated, and the clamp loading / unloading part 36 of the other spare LCD clamp 52 is tightened to achieve replacement.
[0040] When air is supplied, the latches inside the clamp body 37 are pushed out by the air pressure and lock into the slots inside the clamp loading and unloading part 36 (locked and fixed). When air is cut off, the direction of air supply is changed, the latches inside the clamp body 37 are pressed back by the air pressure and disengage from the slots inside the clamp loading and unloading part 36, thereby realizing replacement.
[0041] like Figure 5 As shown, the transfer component 4 is used to photograph the LCD grasped by the multi-axis robot 3, correct the position of the LCD, perform barcode scanning for transfer, and upload the product information to the MES system. The transfer component 4 includes a bracket 41, a transfer camera 42, and a barcode scanning CCD camera 43. Both the barcode scanning CCD camera 43 and the transfer camera 42 are mounted on the bracket 41, which is connected to the machine base 1. The transfer camera 42 performs barcode scanning for transfer on the LCD grasped by the multi-axis robot 3, and the barcode scanning CCD camera 43 is used to photograph the LCD grasped by the multi-axis robot 3 and correct the position of the LCD.
[0042] The fixture library assembly 5 includes multiple fixture placement slots 51 and a spare LCD fixture 52. The fixture placement slots 51 are disposed on the machine base 1, and the spare LCD fixture 52 is located in the fixture placement slots 51.
[0043] Working principle: During loading, the AGV feeds the material into the first conveying and transfer component 2, the system connects, and the material is fed into the machine 1. The elevator 22 lifts it to the highest point, and the multi-axis robot 3 uses the CCD camera 33 to take a CCD visual picture of the material in ... The multi-axis robot 3 performs another CCD vision photograph of the cassette. After photographing the MRAK point of the vehicle LCD, it calibrates and corrects the coordinate system with the cassette to achieve precise placement of the cassette without collision. For different sizes and types of vehicle LCDs, the LCD gripper 35 on the multi-axis robot 3 can be controlled by a pneumatic valve. The gripper changing mechanism puts the LCD gripper 35 back into the gripper library assembly 5. The gripper is then replaced from the gripper library assembly 5. The positioning mechanism automatically controls the on / off of electricity and air, eliminating the need for manual replacement, making it quick and convenient, and improving production efficiency. When replacing the LCD gripper 35, the gripper body 37 is de-purged, the gripper loading / unloading part 36 is loosened, and the LCD gripper 35 is placed together with it in the corresponding gripper placement slot 51. Then, it is moved to the position of another spare LCD gripper 52. The gripper loading / unloading part 36 of the other spare LCD gripper 52 is aligned, the gripper body 37 is vented, and the gripper loading / unloading part 36 of the other spare LCD gripper 52 is tightened to complete the replacement.
