[0043] The working principle of the thermostat automatic assembly machine of this embodiment:
[0044] 1. Semi-finished product placement station: put the semi-finished product from the grating detection area into the bottom mold 12 of the thermostat and then enter the next station.
[0045] 2. Servo rotating shaft station: the rotating shaft is fed by the rotating vibrating feeding plate, and then enters the rotating cylinder 405 through the rotating shaft flow channel 404. The rotating cylinder 405 acts to send the rotating shaft to the rotating shaft clamp 417, and the rotating cylinder 405 resets; The rotating shaft of the conveyor 408 is translated to the top of the thermostat bottom mold 12, and then the first linear cylinder 411 acts to lower the rotating shaft into the thermostat bottom mold 12, and the rotating motor 413 starts to twist the shaft. If there is a defective product in the process of twisting the shaft, the divider will continue to operate, but the remaining stations will stop working until the defective product is sorted out at the defective product sorting station; if there is no defective product in the process of twisting the shaft, it will go to the next process. go in.
[0046] 3. The working method of the porcelain rice installation station between the shrapnel and the double gold: the porcelain rice enters the feeding channel of the feeding block 504 from the external porcelain rice feeding vibrating plate, and the porcelain rice moves along the feeding cylinder 505 under the action of the feeding cylinder 505. The unloading pipe 503 moves toward the porcelain rice assembling device 502. When the porcelain rice incoming sensor (not shown) located above the unloading block 905 detects the porcelain rice, the information is sent to the PLC control system, and the PLC control system controls the blocking The air cylinder 511 is opened to ensure that only one grain of porcelain rice is supplied at a time. The ceramic rice enters the circular hole structure 512 of the clamping block 509 under the action of the feeding cylinder 505. After the optical fiber detection sensor detects the ceramic rice entering the circular hole structure 512, the information is sent to the PLC control system. PLC control The system controls the pusher cylinder 506 to start working, the pusher cylinder 506 drives the centering cylinder 508 to enter the 12th station of the thermostat bottom mold, and then the centering cylinder 508 releases the porcelain rice, and the porcelain rice enters the hole of the bimetal sheet, Next, the centering cylinder 508 is then opened to ensure that the extension part does not contact the metal sheet of the thermostat, the pushing cylinder 506 is retracted, and the whole set of operations is completed.
[0047] 4. The limit piece clamping and installation station: the limit piece is fed by the limit piece vibrating feeding tray, and enters the limit piece dislocation block 605 through the limit piece flow channel 604, and the second lifting cylinder drives the clamping block to carry out Reset after clipping. The first mini-cylinder 619 moves, reaches the top of the bottom mold 12 of the thermostat, and starts to rise and fall, placing the limiting piece on the semi-finished product.
[0048] 5. The ceramic rice installation station in the adjustment shaft of the pressure limit tablet machine: the porcelain rice is divided by the porcelain rice vibrating feeding plate one by one into the porcelain rice lifting tube 703. The porcelain rice lifting cylinder 701 starts to act, and drives the porcelain rice lifting tube 703 to squeeze the limit piece.
[0049] 6. Gluing station: After the bottom mold 12 of the thermostat reaches above the glue station 8, the glue cylinder 803 starts to act after the movement reaches the lifting and moving point, and the glue cylinder 803 resets after the glue is finished.
[0050] 7. Screw station: First, the screws are separated into the screw feeding mechanism by the external screw feeding vibrating plate. After the high-precision optical fiber sensor senses the screws, the feedback signal is sent to the PLC control system. The PLC control system controls the dislocation cylinder 904 start working. The dislocation cylinder 904 drives the dislocation sliding block 903 so that the through holes on the dislocation sliding block 903 communicate with the through holes on the blanking block 905 and the dislocation guide rail 9002 . After the through holes are connected, the screws are driven along the feeding tube to the installation station. After the operation of the misaligned cylinder 904 is completed, it returns to the initial position. When the start signal of the screw installation station is turned on, the lift cylinder starts to rise out of the first section. After reaching the designated position, the screw quickly enters the screw chuck, and the lift cylinder starts to rise out of the second section. The electric screwdriver 912 starts to start, and the lift cylinder returns to the initial position one second after the action is completed. At this point, the assembly process of the screw is completed.
[0051] 8. Finished product station: the finished product is lifted and lowered, and the second manipulator 101 picks the finished product from the bottom mold 12 of the thermostat and puts it into the material box.
[0052] 9. Defective product sorting station: the third manipulator 111 takes out the defective product from the bottom mold 12 of the thermostat, and sends it away through the conveyor belt 112 .
[0053] It can be understood that the PLC control system in this embodiment and the connection or control between the PLC control system and each sensor and each cylinder are in the prior art.
