[0037] See also Figures 1-11, an automatic loading and unloading equipment for plates, including a PLC controller 100, a loading device 200, a frame 300, a material moving device 400, a material unloading device 500 and a material receiving device 600, the material moving device 400, the material unloading device 500 and the material receiving device 600 are all arranged on the frame 300, the PLC controller 100 is connected to the loading device 200, the material moving device 400, the material unloading device 500 and the material receiving device 600, the PLC controller 100 plays a control role, controls the operation of the control device and the coordination between the devices.

[0038] The loading device 200 includes a frame 210, a loading placement mechanism 220, a loading moving mechanism 230 and a loading correction mechanism 240. The loading placement mechanism 220, the loading moving mechanism 230 and the loading correction mechanism 240 are all arranged on the frame 210. The loading placement mechanism 220 is used to stack the plates 800. The loading moving mechanism 230 moves the plates 800 on the loading placement mechanism 220 to the loading correction mechanism 240 in the X-axis direction; specifically, the vertically stacked plates 800 are placed on the loading placement mechanism 220, and the loading moving mechanism 230 moves back and forth between the loading placement mechanism 220 and the loading correction mechanism 240, and conveys a piece of plate 800 once back and forth. The moving direction is the X-axis direction. The material moving device 400 includes a material moving mechanism 410 and a processing platform mechanism 420. The material moving mechanism 410 moves the plate 800 on the loading and correcting mechanism 240 to the processing platform mechanism 420 in the Y-axis direction. The processing platform mechanism 420 is used by the processing device 700 to process the plate 800 thereon; specifically, the material moving mechanism 410 will be placed between the loading and correcting mechanism 240 and the processing platform mechanism 420 and move back and forth, and a piece of plate 800 will be transported once back and forth, and the moving direction is the Y-axis direction. The loading correction mechanism 240 is used to correct the angle of the plate 800 thereon, and cooperates with the loading movement mechanism 230 to correct the X-axis position of the plate 800 thereon and cooperates with the material moving mechanism 410 to correct the Y-axis position of the plate 800 thereon; specifically, the loading movement mechanism 230 moves the plate 800 from the loading placement mechanism 220 to the loading correction mechanism 240, the loading correction mechanism 240 detects the position of the plate 800, and the PLC controller 100 controls the loading movement mechanism 230 to move the plate 800 in the X-axis direction according to the detection result to ensure the consistency of the position in the Y-axis direction, and the loading correction mechanism 240 itself is The plate 800 is adjusted in angle. The PLC controller 100 controls the material moving mechanism 410 to move the plate 800 in the Y-axis direction according to the detection results to ensure the consistency of the position in the X-axis direction. The material moving mechanism 410 then picks up the plate 800 and places it on the processing platform mechanism 420. At this time, the plate 800 can match the processing platform mechanism 420 in both length and width. That is, the plate 800 is corrected in the X-axis direction and the Y-axis direction through the loading and moving mechanism 230 and the material moving mechanism 410, which simplifies the loading and correction mechanism 240 while maintaining the original correction effect. The overall structural setting is more reasonable and coordinated. The unloading device 500 is used to move the plate 800 on the processing platform mechanism 420 to the receiving device 600.

[0039] In this embodiment, the loading and placing mechanism 220 includes a plate stacking assembly and a plate clamping assembly. The plate stacking assembly includes a frame 210, a loading platform 221, and a first cylinder 222. The first cylinder 222 is fixed to the frame 210, the output shaft of the first cylinder 222 is connected to the loading platform 221, and the first cylinder 222 is electrically connected to the PLC controller 100. The plate clamping assembly is provided on the frame 210 and is used to clamp the plates 800 on the frame 210. Specifically, the vertically stacked plates 800 are placed on the loading platform 221, and the first cylinder 222 is used to drive the loading platform 221 to rise. When the top plate 800 is removed, the first cylinder 222 drives the vertically stacked plates 800 to rise, thereby replenishing the height of the plates 800 to ensure that the top plate 800 can be picked up by the loading movement mechanism 230.

[0040] In this embodiment, the plate clamping assembly includes a first fixed plate 223, a second fixed plate 224, a movable plate 225 and a hand-tightening screw 226. The first fixed plate 223 and the second fixed plate 224 are both fixed on the frame 210. The first fixed plate 223 and the second fixed plate 224 are respectively located on both sides of the loading platform 221. The movable plate 225 is provided with a sliding shaft 227. The second fixed plate 224 is provided with a straight hole and a screw hole. The straight hole is arranged in the direction of the first fixed plate 223. The screw hole is perpendicular to and connected to the straight hole. The sliding shaft 227 passes through the straight hole to form a loose fit. The hand-tightening screw 226 passes through the screw hole and its end rests against the sliding shaft 227. When the plate 800 is placed on the loading platform 221, the first fixed plate 223 is used to abut one side of the plate 800. Loosening the hand screw 226 can slide the movable plate 225, and the movable plate 225 is slid to abut the other side of the plate 800. Then, tightening the hand screw 226 fixes the movable plate 225, so that the first fixed plate 223 and the movable plate 225 can limit the two sides of the plate 800. The plate clamping assembly can adjust the distance between the first fixed plate 223 and the movable plate 225 according to the width of the plate 800, thereby limiting plates 800 of different widths and being able to adapt to plates 800 of different sizes, with strong versatility. Here, when the movable plate 225 is adjusted to abut one side of the plate 800, the distance between the movable plate 225 and the first fixed plate 223 is slightly larger than the width of the plate 800, so as to ensure that the plate 800 can move up and down.

[0041] In this embodiment, the loading and placing mechanism 220 further includes a plasma blower 228 and an air blower. The plasma blower 228 and the air blower are both disposed on the first fixed plate 223. The air blower is located below the plasma blower 228. The air blower is connected to a blower. The plasma blower 228 and the blower are both electrically connected to the PLC controller 100. When the loading and moving mechanism 230 picks up the plate 800 on the loading platform 221, the PLC controller 100 controls the plasma blower 228 to turn on. The plasma blower 228 removes static electricity between two adjacent plates 800 to prevent the top plate 800 from moving with the plate 800 below it due to static electricity. At the same time, the PLC controller 100 also starts the blower, and air is blown out from the air blower, using strong wind to separate the top plate 800 from the plate 800 below it.

[0042] In this embodiment, the loading moving mechanism 230 is located above the loading placement mechanism 220, and the loading moving mechanism 230 includes an X-axis drive module 231, a width adjustment component and a first suction component.

It should be noted that the X-axis drive module 231 is a conventional motor and screw structure, specifically the motor is electrically connected to the PLC controller 100; the width adjustment component includes a width adjustment bracket 237 and a width adjustment light rod 238, the width adjustment bracket 237 is arranged on the X-axis drive module 231, the width adjustment light rod 238 is connected to the width adjustment bracket 237, and the second bracket 233 is loosely fitted on the width adjustment light rod 238, that is, the second bracket 233 can be manually slid to adjust the distance between the first bracket 232 and the first bracket 232, and the distance between the first suction cup 235 and the second suction cup 236 can be adjusted according to the actual length of the sucked plate 800, and it has strong versatility. The X-axis drive module 231 drives the first suction assembly to be located above the loading platform 221, the second cylinder 234 drives the first suction cup 235 and the second suction cup 236 to move downward and the exhaust fan is started so that the topmost plate 800 is adsorbed on the first suction cup 235 and the second suction cup 236. After the first suction cup 235 and the second suction cup 236 adsorb the plate 800, the motor 243 drives the X-axis drive module 231 and then drives the first suction assembly to move above the material transfer platform 242. The exhaust fan is turned off to make the first suction cup 235 and the second suction cup 236 release the plate 800, and the plate 800 falls onto the material transfer platform 242, thereby realizing material transfer.

When the plate 800 is placed on the material transfer platform 242, the camera 245 will calibrate the camera 245 with the positioning hole 810 on the plate 800. When there is a deviation between the camera 245 and the positioning hole 810 on the plate 800, the deviation parameter will be transmitted to the PLC controller 100. The PLC controller 100 controls the X-axis drive module 231 to move the plate 800 in the X-axis direction according to the deviation parameter, so that the position of the plate 800 in the X-axis direction is the same as the preset position. The PLC controller 100 will also control the motor 243 according to the deviation parameter to control the movement of the three movable columns 246, thereby controlling the material transfer platform 242 to rotate with the fixed column 244 as the center, thereby adjusting the angle of the plate 800.

[0049] In the present invention, all electronic control actions are controlled and completed by the PLC controller 100.

[0050] The working steps of the present invention are:

[0051] 1. Loading: Place the vertically stacked plates 800 on the loading platform 221. The X-axis drive module 231 moves the first suction cup 235 and the second suction cup 236 to the top of the loading platform 221. The second cylinder 234 drives the first suction cup 235 and the second suction cup 236 to descend. At this time, the exhaust fan connected to the first suction cup 235 and the second suction cup 236 is turned on to make the first suction cup 235 and the second suction cup 236 absorb the top plate 800. The second cylinder 234 drives the plate 800 to move up and down quickly. The plate 800 is lowered to play a shaking role, which plays a role in separating the plate 800 from other plates 800. During the shaking process, the plasma fan 228 and the blower are started to remove static electricity and separate the plate 800 respectively. After the shaking is completed, the X-axis drive module 231 drives the plate 800 to move above the material transfer platform 242, and the second cylinder 234 drives the plate 800 to descend. At this time, the exhaust fan connected to the first suction cup 235 and the second suction cup 236 is turned off to make the plate 800 fall onto the material transfer platform 242;

[0052] 2. Correction: The camera 245 calibrates the positioning holes 810 on the plate 800. When the camera 245 calibrates the positioning holes 810 on the plate 800 and there is a deviation, the deviation parameter will be transmitted to the PLC controller 100. The PLC controller 100 controls the X-axis driving module 231 of the feeding moving mechanism 230 to move the plate 800 in the X-axis direction according to the deviation parameter, so that the position of the plate 800 in the X-axis direction is the same as the preset position in the PLC controller 100 to solve the deviation in the X-axis direction. The PLC controller 100 The motor 243 of the loading and correcting mechanism 240 is also controlled according to the deviation parameter. The motor 243 drives the three movable columns 246 to move, thereby causing the material transfer platform 242 to rotate with the fixed column 244 as the center, thereby adjusting the angle of the plate 800. The PLC controller 100 also controls the material transfer drive module 411 to move the plate 800 in the Y-axis direction according to the deviation parameter, so that the position of the plate 800 in the Y-axis direction is the same as the preset position of the PLC controller 100 to resolve the deviation in the Y-axis direction, thereby achieving a correction effect.

[0053] 3. Material transfer: The material transfer drive module 411 drives the third suction cup to move above the material transfer platform 242. The exhaust fan connected to the third suction cup is turned on to make the third suction cup absorb the plate 800. Then, the material transfer drive module 411 drives the plate 800 to move above the processing platform 421. The exhaust fan connected to the third suction cup is turned off to make the plate 800 fall on the first processing platform 421. The material transfer drive module 411 repeats the above material transfer action to move the next plate 800 to the second processing platform 421. The material transfer drive module 411 repeats the above material transfer action again to move the next plate 800 to the third processing platform 421. The platform transfer module 422 moves the plate 800 to the bottom of the processing head 720.

[0054] 4. Processing: The platform moving module 422 moves the three processing platforms 421 to the bottom of the three processing motors 243. The processing drive module 710 drives the three processing heads 720 to move so that the three processing heads 720 correspond to the three plates 800 one by one. The three processing heads 720 process the plates 800 on the three processing platforms 421 one by one.

[0055] 5. After the processing is completed, the unloading drive module 510 drives the three fourth suction cups to be located above the three plates 800 respectively, and the exhaust fan connected to the fourth suction cups is turned on so that the three fourth suction cups respectively adsorb the three plates 800. The unloading drive module 510 drives the plates 800 to move above the three receiving frames 620 of the receiving device 600, and the exhaust fan connected to the fourth suction cups is turned off so that the three plates 800 fall into the three receiving frames 620 respectively, thus completing the material collection.
