[0076] Under the joint action of the switch spring and the switch sliding screw 4532, the compressed switch spring of the switch component 4531 abuts against the end of the switch sliding screw 4532 away from the storage barrel 452, and the switch through hole 4539 on the switch component 4531 is staggered with the loading hole 4521 at the bottom of the storage barrel 452.

[0083] The working principle of the feeding device 4 of the present application is as follows: in order to facilitate the transport of the filters 9 in 452 to the position where the filter retrieval and placement mechanism 3 can pick them up, a plurality of filters 9 are first stored in the storage barrel 452, and then the storage barrel 452 is fixed to the fixed connecting frame 451; the lowest filter 9 in the storage barrel 452 passes through the switch hole 4539, the feeding hole 4521 and the feeding hole 4591 in sequence, and falls on the upper surface of the rear end of the material pushing and blocking member 443. Before the filter 9 is pushed from the storage mechanism 45 to the first limiting track groove 431, the material sensor 427 is used to detect whether there is a filter 9 in the blocking and limiting member 426, and then the lifting cylinder 422 is used to drive the material holding assembly 423 to move downward to the maximum stroke, and then the first pushing cylinder 432 is used to drive the pushing member 433 to move away from the material holding assembly 423 to the maximum stroke. When the filter 9 needs to be pushed from the storage mechanism 45 into the first limiting track groove 431, the second pushing cylinder 442 first drives the pushing stopper 443 to move away from the first limiting track groove 431 to the rear end of the second limiting track groove 441 (when the pushing stopper 443 moves toward the rear end, the filter 9 is on the upper surface of the pushing stopper 443), and the filter 9 falls from the feeding hole 4591 into the second limiting track groove 441 (at this time, the filter 9 is located at the front end of the curved surface of the pushing stopper 443). Then, the second pushing cylinder 442 drives the pushing stopper 443 to push the filter 9 toward the first limiting track groove 431; when it moves to the maximum stroke of the second pushing cylinder 442, the filter 9 falls from the dropping hole 448 into the first limiting track groove 431. After the second pushing cylinder 442 drives the pushing and stopping member 443 to move to the maximum stroke in the direction of the first limiting track groove 431, the first pushing cylinder 432 drives the pushing member 433 to move in the direction of the material receiving assembly 423; in the process of the pushing member 433 moving in the direction of the material receiving assembly 423, the pushing member 433 will push a filter 9 that falls from a drop hole 448 into the first limiting track groove 431 and push it into the material stopping member 426 of the material receiving assembly 423. When the material sensor 427 detects that there is a filter 9 in the material stopping member 426 and the forward and reverse sensor 428 detects that the wide side of the filter 9 in the material stopping member 426 is facing downward (such as Figure 13 As shown), the lifting cylinder 422 drives the material holding component 423 to move upward to the maximum stroke, so that the vacuum suction nozzle 311 above the material holding component 423 can suck the filter 9.

[0084] The working principle of the filter picking and placing mechanism 3 of the present application is as follows: after the lifting cylinder 422 drives the filter 9 placed in the material holding component 423 and facing the correct direction to move upward to the maximum stroke, the lifting component 32 drives the picking and placing component 31 to move upward through the lifting connection 321; the driving motor 333 drives the slide 332 to drive the lifting component 32 to move toward the upper feeding device 4. When the picking and placing component 31 is above the material holding component 423, the lifting component 32 drives the picking and placing component 31 and the vacuum suction nozzle 311 to move downward to the maximum stroke (at this time, the vacuum suction nozzle 311 is in contact with the upper surface of the filter 9); then, the vacuum generator is started, and the vacuum suction nozzle 311 sucks the filter 9 in the material stop limiter 426, and the lifting component 32 drives the picking and placing component 31, the vacuum suction nozzle 311 and the sucked filter 9 to move upward to the maximum stroke; then, the driving motor 333 drives the slide 332 to drive the lifting component 32 to pick and place the component 31, the vacuum suction nozzle 311 and the sucked filter 9 to A lower cover sealing ring 121 is above the lifting component 32, and then the filter 9 is driven downward to the top of the lower cover sealing ring 121 through the pick-and-place component 31 and the vacuum suction nozzle 311, so that the filter 9 is driven to move to the bottom of the upper cover sealing ring 111 through the translation mechanism 2 and the liquid inlet upper cover 11 and the upper cover sealing ring 111 are driven downward to the maximum stroke by the driving cylinder 131, and then the solution to be filtered is filtered through the filtering mechanism 1 and the filter 9; after the vacuum generator connected to the vacuum suction nozzle 311 is closed, the lifting component 32 drives the pick-and-place component 31 and the vacuum suction nozzle 311 to move upward to the maximum stroke. When the translation mechanism 2 drives the filter 9 that has been filtered for a period of time to the bottom of the filter pick-up and placement mechanism 3, the lifting assembly 32 drives the pick-up and placement assembly 31 and the vacuum suction nozzle 311 to move downward to the maximum stroke (at this time the vacuum suction nozzle 311 is in contact with the upper surface of the filter 9); then, the vacuum generator is started, and the vacuum suction nozzle 311 sucks the filtered filter 9 between several limiting protrusions 122, and the lifting assembly 32 drives the pick-up and placement assembly 31, the vacuum suction nozzle 311 and the sucked filtered filter 9 to move upward to the maximum stroke; then, the driving motor 333 drives the slide 332 to drive the lifting assembly 32 pick-up and placement assembly 31, the vacuum suction nozzle 311 and the sucked filtered filter 9 to move above the waste feeding port 71, and then the vacuum generator is closed, and the filtered filter 9 falls downward, and after passing through the waste feeding port 71, falls into the waste bin 72.

[0085] The working principle of the solution filtering device of the present application is as follows: when the translation mechanism 2 drives the filter 9 placed between several limiting protrusions 122 to move to the bottom of the upper cover sealing ring 111, the driving cylinder 131 drives the liquid inlet upper cover 11 and the upper cover sealing ring 111 downward to the maximum stroke through the moving part 132, and the filter 9 is fixed between the liquid inlet upper cover 11 and the liquid outlet lower cover 12, and the upper and lower surfaces of the filter 9 are respectively in sealing contact with the upper cover sealing ring 111 and the lower cover sealing ring 121. Then, the solution to be filtered in the beaker 81 is passed through the liquid inlet 511, the liquid inlet pump, the liquid inlet pipe 512, the liquid inlet upper cover 11, the liquid outlet lower cover 12, the liquid outlet pipe 522 and the liquid outlet part 521 in sequence, and the filtered solution is introduced into the transfer container 55; the solution to be filtered is filtered between the upper and lower surfaces of the filter 9, and the solid particles in the solution to be filtered are filtered on the upper surface of the filter paper of the filter; if a small amount of filtrate overflows, the overflowed solution is first collected in the first liquid collecting tank 216, and then the overflowed solution flows through the liquid hole and the liquid pipe 218 in sequence and flows into the second liquid collecting tank 217, and then the overflowed solution flows through the leakage hole and the leakage pipe 219 set on both sides of the linear module 23 and flows out to the fixed plate 25, and the overflowed solution will not flow into the linear module 23.

[0086] The working principle of the liquid inlet and outlet device 5 of the present application is as follows: before filtering the solution to be filtered in the beaker 81, the beaker 81, the transfer container 55 and the solution bottle 82 are placed on the driving turntable 56 in sequence by a robot or manually; then the first moving cylinder 513 drives the liquid inlet part 511 to move downward to the beaker 81, the second moving cylinder 523 drives the liquid outlet part 521 and the transfer liquid inlet part 543 to move downward to the transfer container 55, and the third moving cylinder 541 drives the transfer liquid outlet part 542 to move downward to the bottle mouth of the solution bottle 82. During solution filtration, the solution to be filtered in beaker 81 passes sequentially through liquid inlet 511, liquid inlet pump, liquid inlet pipe 512, liquid inlet upper cover 11, liquid outlet lower cover 12, liquid outlet pipe 522, and liquid outlet 521, and then is introduced into transfer container 55. The filtered solution in transfer container 55 then passes sequentially through transfer liquid inlet 543, transfer pipe, transfer pump, transfer pipe, and transfer liquid outlet 542, and then into solution bottle 82. After the transfer pump determines that the volume of the filtered solution introduced into solution bottle 82 is 1L or 2L, it is turned off. When the volume of the solution introduced into the solution bottle 82 reaches the required 1L or 2L and there is no solution to be filtered in the beaker 81, the empty beaker 81 can be replaced with a beaker 81 filled with the solution to be filtered by the robot; when there is no solution to be filtered in the beaker 81, the empty beaker 81 can be replaced with a beaker 81 filled with the solution to be filtered by the robot; when the volume of the solution introduced into the solution bottle 82 reaches the required 1L or 2L, the solution bottle 82 that meets the requirements can be replaced with a clean solution bottle 82 by the robot or manually. After the liquid inlet part 511, the driven liquid outlet part 521, the transfer liquid inlet part 543 and the transfer liquid outlet part 542 have been filtered for a period of time, when cleaning is required, the first movable cylinder 513 can be used to drive the liquid inlet part 511 to move upward to the maximum stroke, the second movable cylinder 523 can drive the liquid outlet part 521 and the transfer liquid inlet part 543 to move upward to the maximum stroke, and the third movable cylinder 541 can drive the transfer liquid outlet part 542 to move upward to the maximum stroke; then, the turntable 56 is driven to rotate by the turntable drive motor 561, and the first cleaning bucket 571 is rotated to the bottom of the liquid inlet part 511, the second cleaning bucket 572 is rotated to the bottom of the driven liquid outlet part 521 and the transfer liquid inlet part 543, and the third cleaning bucket 573 is rotated to the bottom of the transfer liquid outlet part 542. Then, the first movable cylinder 513 drives the liquid inlet 511 downward into the first washing bucket 571. The second movable cylinder 523 drives the liquid outlet 521 and the transfer liquid inlet 543 downward into the second washing bucket 572. The third movable cylinder 541 drives the transfer liquid outlet 542 downward into the third washing bucket 573. Then, purified cleaning water or cleaning solution is introduced into the first washing bucket 571, the second washing bucket 572, and the third washing bucket 573 through the cleaning pipes, respectively, to clean the liquid inlet 511, the driving liquid outlet 521, the transfer liquid inlet 543, and the transfer liquid outlet 542.After the liquid inlet 511, the driven liquid outlet 521, the transfer liquid inlet 543, and the transfer liquid outlet 542 are cleaned, the clean water or cleaning solution is discharged through the cleaning drain pipe, and the liquid inlet 511, the driven liquid outlet 521, the transfer liquid inlet 543, the transfer liquid outlet 542, the first cleaning bucket 571, the second cleaning bucket 572, and the third cleaning bucket 573 are blown dry with a high-pressure air nozzle. After the liquid inlet 511, the driven liquid outlet 521, the transfer liquid inlet 543, and the transfer liquid outlet 542 are blown dry, the first movable cylinder 513 can be used to drive the liquid inlet 511 upward to its maximum stroke, the second movable cylinder 523 can drive the liquid outlet 521 and the transfer liquid inlet 543 upward to their maximum stroke, and the third movable cylinder 541 can drive the transfer liquid outlet 542 upward to its maximum stroke. When cleaning the liquid inlet pipe 512, the liquid outlet pipe 522, and the filter mechanism 1, the filter 9 on the liquid inlet lower cover 12 can be sucked up by the filter placement mechanism 3, and then the drive assembly 13 can be used to drive the liquid inlet upper cover 11 toward the liquid outlet lower cover 12, so that the upper cover sealing ring 111 and the lower cover sealing ring 121 are in sealed contact. Then, the cleaning water in the first cleaning bucket 571 is introduced into the second cleaning bucket 572 through the liquid inlet part 511, the liquid inlet pump, the liquid inlet pipe 512, the liquid inlet upper cover 11, the liquid outlet lower cover 12, the liquid outlet pipe 522, and the liquid outlet part 521, thereby cleaning the filter mechanism 1. When cleaning the transfer pipe, the cleaning water in the transfer container 55 can be introduced into the solution bottle 82 after passing through the transfer liquid inlet part 543, the transfer pipe, the transfer pump, the transfer pipe, and the transfer liquid outlet part 542.
