Description

[0001] The present invention relates to the technical field of corona treatment for dialyzer housings, and particularly to an automatic corona treatment device for dialyzer housings. Background Art

[0002] The existing treatment methods for PP dialyzer housings mostly adopt plasma flame spraying treatment, and an infrared temperature sensor is used to detect whether the PP dialyzer housing needs to be processed by the equipment. A large number of active particles such as ions, excited molecules, and free radicals in the plasma act on the surface of the solid sample to remove the original pollutants and impurities on the surface, so as to increase the tension value of the PP material. At the same time, it will have an etching effect on the PP dialyzer housing, making the surface of the PP dialyzer housing rough and forming many fine pits, thereby improving the hydrophilicity of the material. However, the plasma flame spraying treatment method needs to reciprocally process the PP dialyzer housing at least 3 times, with a slow processing speed and affecting the production efficiency.

[0053] Under the control of the PLC control system 6, the shell conveyor line 3 is used to convey the dialyzer shell 10 (especially the PP dialyzer shell). The shell alignment device 4 aligns the respective dialyzer shells 10 on the shell conveyor line 3 (that is, the end faces of two adjacent dialyzer shells 10 are aligned), which facilitates the corona treatment device 5 to quickly corona-treat the aligned dialyzer shells 10. The working efficiency of this automatic dialyzer shell corona treatment device is high, the automation is high, the corona treatment time only needs 2S, and the whole process only needs 6S.

[0055] Preferably, the shell support frame is a U-shaped support frame. According to the structure of the dialyzer shell 10, the shell support frame is designed as a U-shaped support frame, which helps to improve the stability of conveying the dialyzer shell 10 and enables stable conveyance.

[0056] The housing alignment device 4 includes an alignment sensor and two housing pushing devices 41 that are relatively arranged on the workbench 1 and located on both sides of the housing conveyor line 3; the housing pushing device 41 includes a mounting seat 411, an alignment pushing cylinder 412, and a double alignment pressing block 413. Among them, the alignment sensor is arranged on the workbench 1 or the frame 2 and is used to sense the dialyzer housing 10 on the housing conveyor line 3. If the dialyzer housing 10 is sensed, detection information is generated and fed back to the PLC control system 6; the alignment sensor is an infrared sensor. The mounting seat 411 is arranged on the workbench 1; the alignment pushing cylinder 412 is arranged on the mounting seat 411; the double alignment pressing block 413 is connected to the alignment pushing cylinder 412 and is used to simultaneously press the end faces of two dialyzers; the two opposite alignment pushing cylinders 412 simultaneously drive the corresponding double alignment pressing blocks 413 to move relatively to press the two dialyzer housings 10 to be aligned with each other; the PLC control system 6 is electrically connected to the alignment sensor and the alignment pushing cylinder 412 respectively. The alignment sensor senses the dialyzer housing 10 to generate detection information and feeds the detection information back to the PLC control system 6; the PLC control system 6 controls the two alignment pushing cylinders 412 to work simultaneously, and the two opposite alignment pushing cylinders 412 simultaneously drive the corresponding double alignment pressing blocks 413 to move relatively to press the two end faces of the two dialyzer housings 10 to be aligned with each other. The two end faces of the two dialyzer housings 10 are aligned at one time, with high efficiency, laying a foundation for the corona treatment, so as to improve the overall efficiency of the equipment.

[0057] The corona treatment device 5 includes a corona sensor, a fixed seat 51, a corona pushing cylinder 52, an electrode head 53, a housing lifting device 54, a housing pressing device 55, a corona pulse detection mechanism 56, and a corona generator 57. Among them, the corona sensor is located on the workbench 1; the corona sensor is an infrared sensor; the two fixed seats 51 are respectively located on both sides of the housing conveying line 3; the corona pushing cylinder 52 is provided on each fixed seat 51; each electrode head 53 is connected to the corresponding pushing cylinder and is located above the housing conveying line 3; the housing lifting device 54 is provided on the workbench 1 and is used to lift the dialyzer housing 10 on the housing conveying line 3 to the concentric height of the electrode head 53; the housing pressing device 55 is provided on the frame 2 and is located above the housing conveying line 3 and is used to cooperate with the housing lifting device 54 to press the dialyzer housing 10 tightly; the corona pulse detection mechanism 56 is located on the frame 2 relative to the position of the electrode head 53; the corona generator 57 is provided on the frame 2 and is electrically connected to the electrode head 53; after the dialyzer and the electrode head 53 reach the concentric height, the two opposite corona pushing cylinders 52 simultaneously drive the corresponding electrode heads 53 to be tightly sleeved with the two ends of the dialyzer housing 10; the PLC control system 6 is respectively electrically connected to the corona sensor, the corona pushing cylinder 52, the housing lifting device 54, the housing pressing device 55, the corona pulse detection mechanism 56, and the corona generator 57.

[0058] After the dialyzer housing 10 is aligned, the corona sensor should detect the dialyzer housing 10 to generate detection information and feedback the detection information to the PLC control system 6; under the control of the PLC control system 6, the housing conveying line 3 reaches a specified position to stop transporting the dialyzer housing 10, the housing lifting device 54 lifts the dialyzer housing 10 on the housing conveying line 3 to the concentric height of the electrode head 53, the housing pressing device 55 works and cooperates with the housing lifting device 54 to tightly press the dialyzer housing 10 to keep the dialyzer housing 10 in good stability, and then the two opposite corona pushing cylinders 52 simultaneously drive the corresponding electrode heads 53 to be tightly sleeved with the two ends of the dialyzer housing 10. At this time, the transformer of the corona generator 57 is powered on, and the electricity is transported to the electrode head 53 through the high-voltage wire for discharging to perform corona treatment on the dialyzer housing; the principle of corona treatment is to apply high-frequency high-voltage electricity to cause corona discharge to generate small and dense purple-blue sparks. Under the action of a strong electric field, various plasmas generated after air ionization accelerate to impact the dialyzer housing 10 inside the treatment electrode head 53. These plasma particles can induce the chemical bond breakage and degradation of the molecules on the surface of the dialyzer housing 10, increasing the surface roughness. Corona treatment can remove oil stains, water vapor, dust and dirt, etc.

[0059] After the corona treatment is completed, the two corona driving cylinders 52 drive the corresponding electrode heads 53 to separate from both ends of the dialyzer housing 10 and reset and retract at the same time. The housing pressing device 55 automatically leaves the dialyzer housing 10, and the housing lifting device 54 sends the dialyzer housing 10 back to the housing support frame of the housing conveyor line 3. The housing conveyor line 3 continues to transport the dialyzer housing 10. At this time, the PLC system will judge whether the dialyzer housing 10 has been corona-treated according to the pulse value detected by the corona pulse detection mechanism 56 during the corona treatment process, and then distinguish the treated and untreated dialyzer housings 10, namely the good-quality dialyzer housing 10 and the defective dialyzer housing 10 respectively.

[0060] Through the operation of the corona treatment device 5, this corona treatment method is simple to operate and will not cause situations such as melting and damage of the dialyzer housing 10. The corona treatment of the dialyzer housing 10 is stable and efficient. And by monitoring the discharge pulse quantity to judge whether the dialyzer housing has been treated, this detection method has a lower misjudgment rate than the existing temperature detection and is more efficient. Thus, the working efficiency of this automatic corona treatment device for dialyzer housings is high. The corona treatment time only needs 2S, and the whole process only needs 6S. Compared with the efficiency of the existing plasma treatment equipment, it is twice as fast.

[0061] Among them, the housing lifting device 54 includes a lifting electric cylinder group 541, a support plate 542, a support frame 543 and a housing lifting bracket 544; the lifting electric cylinder group 541 is arranged below the workbench 1; the support plate 542 is connected to the lifting electric cylinder group 541 and is located below the workbench 1; the two support frames 543 are distributed on the support plate 542 and can move through the workbench 1 and are respectively located on both sides of the housing conveyor line 3; the housing lifting bracket is provided on each support frame 543; the lifting electric cylinder group 541 drives the support plate 542, the support frame 543 and the housing lifting bracket 544 to move upward to lift the dialyzer housing 10 on the housing conveyor line 3 to the concentric height of the electrode head 53; the housing pressing device 55 includes a downward pressing electric cylinder group 551 arranged on the frame 2 and a downward pressing head 552 connected to the downward pressing electric cylinder group 551 and used for pressing down the dialyzer housing 10; the PLC control system 6 is electrically connected to the lifting electric cylinder group 541 and the downward pressing electric cylinder group 551. Among them, the lifting electric cylinder group 541 and the downward pressing electric cylinder group 551 can be replaced by air cylinders. Under the control of the PLC control system 6, when the housing conveyor line 3 reaches the specified position to stop transporting the dialyzer housing 10, the lifting electric cylinder group 541 drives the support plate 542 and the support frame 543 to move upward, pushes the support frame 543 to move upward through the workbench 1, and the lifting bracket moves upward synchronously with the support frame 543, just lifting the dialyzer housing 10 on the housing conveyor line 3 to the concentric height of the electrode head 53. At the same time, the downward pressing electric cylinder group 551 drives the downward pressing head 552 to move downward, and acts with the lifting bracket to press the dialyzer housing 10, enhancing the stability of the dialyzer housing 10, which helps the electrode head 53 to be sleeved tightly with the dialyzer housing 10, so as to facilitate the corona treatment of the dialyzer housing 10. After the corona treatment is completed, the downward pressing electric cylinder group 551 drives the downward pressing head 552 to reset, and the lifting electric cylinder group 541 drives the support plate 542, the support frame 543 and the lifting bracket to reset, and the dialyzer housing 10 is sent back to the housing conveyor line 3, with high automation and high efficiency.

At the same time, the double bracket part is a U-shaped double bracket part; the double pressing part is a U-shaped double pressing part, enhancing the stability acting on the dialyzer housing 10.

After the corona treatment is completed, the PLC control system 6 divides the dialyzer outer shell 10 into a good dialyzer outer shell 10 and a defective dialyzer outer shell 10. Under the control of the PLC control system 6, the crossbeam manipulator 7 transports the good dialyzer outer shell 10 on the outer shell conveyor line 3 to the good product placement area 8, and the defective dialyzer outer shell 10 to the defective product placement area 9, with high automation and high efficiency.

[0065] Specifically, the crossbeam manipulator 7 includes a crossbeam electric cylinder guide rail group 71, a lifting cylinder 72, and an electric mechanical clamp 73; the crossbeam electric cylinder guide rail group 71 is provided on the frame 2 and straddles the end of the outer shell conveyor line 3, the good product placement area 8, and the defective product placement area 9; the crossbeam electric cylinder guide rail group 71 is connected to the lifting cylinder 72 and drives the lifting cylinder 72 to reciprocate at the end of the outer shell conveyor line 3, the good product placement area 8, and the defective product placement area 9; the lifting cylinder 72 is connected to the automatic mechanical clamp and drives the automatic mechanical claw to reciprocate up and down; the electric mechanical clamp 73 includes a claw cylinder and a mechanical claw, and the mechanical claw is driven by the claw cylinder to automatically pick up and place the dialyzer outer shell 10. Through the action of the crossbeam electric cylinder guide rail group 71 and the lifting cylinder 72, it is helpful for the electric mechanical clamp 73 to move and facilitate the automatic picking up and placing of the dialyzer outer shell 10 in different areas.

[0066] The working process of the present invention is as follows:

[0067] The PLC control system 6 is equipped with control buttons. After pressing the control buttons, the dialyzer housing 10 automatically conveys the dialyzer housing 10. The alignment sensor senses the dialyzer housing 10 to generate detection information and feeds the detection information back to the PLC control system 6. The PLC control system 6 controls the two alignment push cylinders 412 to work simultaneously, and the two opposite alignment push cylinders 412 simultaneously drive the corresponding double alignment pressing blocks 413 to move relatively to push and align the two end faces between the two dialyzer housings 10.

[0068] After the dialyzer housings 10 are aligned, the corona sensor senses the dialyzer housings 10 to generate detection information and feeds the detection information back to the PLC control system 6. Under the control of the PLC control system 6, the housing conveying line 3 reaches the specified position to stop the transportation of the dialyzer housing 10. The housing lifting device 54 lifts the dialyzer housing 10 on the housing conveying line 3 to the concentric height of the electrode head 53. The housing pressing device 55 works in cooperation with the housing lifting device 54 to press the dialyzer housing 10 tightly, so that the dialyzer housing 10 maintains good stability. Then, the two opposite corona push cylinders 52 simultaneously drive the corresponding electrode heads 53 to fit and tighten with the two ends of the dialyzer housing 10. At this time, the transformer of the corona generator 57 is powered on, and the electricity is transported to the electrode head 53 through the high-voltage wire for discharging to perform corona treatment on the dialyzer housing. The principle of corona treatment is to apply high-frequency high-voltage electricity to cause corona discharge to generate fine and dense purple-blue sparks. Under the action of a strong electric field, various plasmas generated after the air is ionized accelerate to impact the dialyzer housing 10 inside the electrode head 53. These plasma particles can induce the breaking of chemical bonds of the molecules on the surface of the dialyzer housing 10 and degrade, increasing the surface roughness. Corona treatment can remove oil stains, water vapor, dust and dirt, etc.

[0069] After the corona treatment is completed, the two corona push cylinders 52 simultaneously drive the corresponding electrode heads 53 to separate from the two ends of the dialyzer housing 10 and reset and retract. The housing pressing device 55 automatically leaves the dialyzer housing 10. The housing lifting device 54 sends the dialyzer housing 10 back to the housing support frame of the housing conveying line 3. The housing conveying line 3 continues to transport the dialyzer housing 10. At this time, the PLC system will judge whether the dialyzer housing 10 has been corona-treated according to the pulse value detected by the corona pulse detection mechanism 56 during the corona treatment process, and then distinguish the treated and untreated dialyzer housings 10 into good-quality dialyzer housings 10 and defective dialyzer housings 10 respectively. The crossbeam manipulator 7 transports the good-quality dialyzer housings 10 on the housing conveying line 3 to the good-quality placement area 8.
