Description

Technical Field

[0001] The present invention relates to an automated processing device for reverse osmosis membrane elements and its working method. Background Art

[0002] Reverse osmosis membrane elements are a highly efficient water separation technology and are widely used in household and industrial applications. In a household environment, this technology is mainly used to purify tap water, effectively removing impurities such as iron, copper, cadmium, chromium, lead, etc., so as to provide high-quality drinking water and cooking water. In addition, it can also be used for the purification of cement floors and swimming pool water. In the industrial field, reverse osmosis membrane elements are widely used in multiple industries such as water treatment, beverage production, electronics manufacturing, chemical industry, food processing, etc., and can convert wastewater, seawater, groundwater, etc. into high-quality pure water. There are significant differences between household and industrial reverse osmosis membranes in terms of application scenarios, filtration performance, and structural design. Household membranes are characterized by miniaturization, lightweight, easy installation, and easy maintenance. Their filtration accuracy is usually 0.0001 microns, which can remove most impurities and bacteria, but the treatment effect on pathogenic viruses and chemical pollutants is limited. In contrast, industrial reverse osmosis membranes are applied to large-scale water treatment systems, with higher filtration accuracy reaching 0.00001 microns, which can effectively remove bacteria, viruses, solvents, heavy metals, radioactive elements, etc. in water, providing high-quality pure water for various industrial production scenarios.

[0003] Currently, in the production process of industrial nano reverse osmosis membrane elements, each link including the cutting, lamination, and winding of key materials such as membrane sheets is completed separately by different mechanical equipment, and then relies on manual handling to the next equipment for continuous processing. This approach not only slows down the production efficiency and increases the production cost due to manual intervention, but also exposes the problems of insufficient automation and intelligence levels. More seriously, given the large size of industrial reverse osmosis membrane elements, manual handling is extremely inconvenient, and it is easy to cause scratches or damage to the elements during the handling process, which directly affects the filtration performance of the finished elements and leads to an increase in the rejection rate.

[0004] Chinese Patent with Publication No. CN118217822A discloses an automated processing device for the previous process of industrial reverse osmosis membrane elements, which can complete the fully automated production of industrial reverse osmosis membranes, including a folding and cutting mechanism, a central tube feeding and film pasting mechanism, and an automatic film winding mechanism. However, this mechanism needs to move in two directions of X and Y, with a complex structure, which will increase the cost in actual engineering. The other solutions found are the automation achieved by a certain program, and the entire process is not fully automated.

[0005] With the development of society and the progress of technology, the awareness of environmental protection and health has been increasing day by day. The market demand for industrial reverse osmosis membrane elements and the quality requirements have both increased significantly, and more stringent standards have been put forward for their accuracy and output. Therefore, there is an urgent need to develop a processing equipment for industrial permeable membrane elements that can achieve high-precision, highly automated, and high-efficiency production to meet the current and future market demands.

Both the upper pressure roller and the lower pressure roller are installed on the frame, and the upper pressure roller and the lower pressure roller are arranged one above the other.

[0012] A vibration mechanism is arranged between the pallet mechanism and the film winding mechanism in the present invention. The vibration mechanism includes a vibration roller and a vibration roller driving device; the vibration roller is installed on the frame in a lifting manner; the vibration roller driving device is installed on the frame and is connected to the vibration roller.

[0013] The film rubbing device described in the present invention further includes a film rubbing pressing plate and a film rubbing pressing plate rotating mechanism. The film rubbing pressing plate is rotatably installed on the frame, and the film rubbing pressing plate rotating mechanism is connected to the film rubbing pressing plate.

[0014] A film material press is installed on the glue coating platform described in the present invention.

[0015] A working method of an automatic processing equipment for reverse osmosis membrane elements includes the following steps: (1) Unwind the reverse osmosis membrane material reel on the reverse osmosis membrane material die opening mechanism, and the reverse osmosis membrane material enters the tape sticking mechanism, and the tape sticking mechanism sticks a tape on the reverse osmosis membrane material; (2) The reverse osmosis membrane material with the tape stuck enters the reverse osmosis membrane material platform. At this time, the film material lifting mechanism is in the low position, and the clamping opening of the film material clamp faces the reverse osmosis membrane material; the front part of the reverse osmosis membrane material enters the clamping opening of the film material clamp, and the film material clamp clamps and fixes the front part of the reverse osmosis membrane material. Then the flipping mechanism operates to drive the inner top plate to flip upward and be in a vertical position. At the same time, the film material lifting mechanism drives the clamping device to rise, and the clamping device drives the reverse osmosis membrane material to rise, and the rising reverse osmosis membrane material is in a vertical state; Meanwhile, the guide net cloth reel on the guide net cloth film opening mechanism opens the film, and the guide net cloth enters the guide net cloth platform; after the handling manipulator clamps the front end of the guide net cloth, it inserts the front end of the guide net cloth onto the reverse osmosis membrane material lifted by the membrane material lifting mechanism, so that the upper and lower surfaces of the front end of the guide net cloth are superposed with the reverse osmosis membrane material; the handling manipulator continues to hold the guide net cloth and moves forward, and conveys the superposed part of the guide net cloth and the reverse osmosis membrane material into the superposition fixture, and the superposition fixture clamps the superposed part; the handling manipulator releases the guide net cloth, then clamps both sides of the superposed part, the superposition fixture releases the superposed part, and the handling manipulator drives the superposed part forward to the gluing platform, and at the same time the membrane material lifting mechanism drives the reverse osmosis membrane material to descend; during the process of the handling manipulator clamping the superposed part and moving forward, the tape on the reverse osmosis membrane material is bonded to the guide net cloth, so that the reverse osmosis membrane material and the guide net cloth are bonded and fixed to form the first membrane material; after the first membrane material reaches the set length dimension, the cutting mechanisms on the reverse osmosis membrane material platform and the guide net cloth platform respectively cut the reverse osmosis membrane material and the guide net cloth, and then the handling manipulator lays the first membrane material flat on the gluing platform, and the gluing manipulator glues the first membrane material on the gluing platform; (III). For the semi-finished reverse osmosis membrane element produced, its inlet spacer is in an unfolded state on the semi-finished product; the handling manipulator puts the semi-finished reverse osmosis membrane element into the winding machine, and at the same time lays the unfolded inlet spacer on the rack; (IV). The handling manipulator lays the glued first membrane material flat on the moving pallet, and then continues to move forward with the first membrane material. The front part of the first membrane material spreads onto the fixed pallet after crossing the moving pallet, and the rear part of the first membrane material still lies on the moving pallet; the handling manipulator releases the first membrane material, and the pallet moving mechanism drives the moving pallet to move backward, and the rear part of the first membrane material gradually spreads onto the fixed pallet until the entire first membrane material spreads onto the fixed pallet; (V). The film rubbing roller moving mechanism drives the film rubbing roller and the film rubbing roller driving mechanism to move. The film rubbing roller presses on the unfolded inlet spacer, and the film rubbing roller rotating mechanism drives the film rubbing roller to rotate. The film rubbing roller rubs the inlet spacer upward, so that a space with a certain gap is formed between the inlet spacer and the rack; After the handling manipulator extends into the space between the inlet spacer and the rack and clamps the inlet spacer, the film rubbing roller moving mechanism drives the film rubbing roller and the film rubbing roller driving mechanism to reset, and the film rubbing roller leaves the inlet spacer; the handling manipulator lays the inlet spacer flat on the first membrane material on the fixed pallet, and the inlet spacer and the first membrane material are bonded and fixed together to form the second membrane material; (VI). The gluing manipulator glues the inlet spacer of the second membrane material; (VII). The winding machine works to perform the winding operation on the semi-finished reverse osmosis membrane element; (8) After the operation of the winding film is completed, the handling manipulator conveys the semi-finished reverse osmosis membrane element to the film sealing mechanism, and the film sealing mechanism performs film sealing operation on the outermost layer of the semi-finished reverse osmosis membrane element, and finally manufactures the finished reverse osmosis membrane element.

[0016] The lamination mechanism of the present invention further includes a pressure roller mechanism, which includes an upper pressure roller and a lower pressure roller. Both the upper pressure roller and the lower pressure roller are installed on the frame, and the upper pressure roller and the lower pressure roller are arranged vertically; in step (2), the handling manipulator grabs the diversion net cloth and moves forward, and the laminated part of the diversion net cloth and the reverse osmosis membrane material first passes through the pressure roller mechanism, that is, between the upper pressure roller and the lower pressure roller. The upper and lower layers of the reverse osmosis membrane material in the laminated part are respectively closely attached to the upper pressure roller and the lower pressure roller; during the process of the handling manipulator clamping the laminated part and moving forward, under the pressure action of the upper pressure roller and the lower pressure roller, the upper and lower layers of the reverse osmosis membrane material are tightly pressed on the upper and lower surfaces of the diversion net cloth.

[0017] Compared with the prior art, the present invention has the following advantages and effects: 1. In the present invention, the automated production of processes such as cutting, clamping, lifting, cutting, tape flat pasting, glue coating, and film material curling of the film material is realized, which has the advantages of high precision and high production efficiency, and significantly reduces the labor cost.

[0018] 2. The film material lifting mechanism is a device for lifting the film material, which greatly optimizes the operation process of inserting the diversion net cloth into the film material. The prior art adopts a flat pasting method, that is, during the operation, both the diversion net cloth and the reverse osmosis membrane material are in a horizontal state, and it is difficult to insert the diversion net cloth, and it is easy to have position deviation or unsmooth insertion. After the film material lifting mechanism of the present invention lifts the film material, it provides more convenient and efficient operation conditions for the insertion of the diversion net cloth, enables the diversion net cloth to be easily and accurately inserted into the reverse osmosis membrane material, effectively improves the quality and efficiency of the lamination of the diversion net cloth and the reverse osmosis membrane material, and ensures the smooth progress of the entire production process.

[0019] 3. Different from the prior art that only uses a manipulator to transport the first film material, in the present invention, with the cooperation of the manipulator and the pallet mechanism, the handling manipulator can keep the first film material flat during the transfer process without folding, preventing the first film material after glue coating from sticking during the transfer process.

[0020] 4. The film rubbing device can rub the water inlet separation net upwards, so that a certain gap space is formed between the water inlet separation net and the rack for the clamping operation of the handling manipulator, without damaging the film material structure. Without this space, the handling manipulator may damage the water inlet separation net during the clamping process. Description of the Drawings

[0054] II. A working method of an automatic processing equipment for reverse osmosis membrane elements, comprising the following steps: (1) Unwind the reverse osmosis membrane material on the reverse osmosis membrane material unwinding mechanism 1 of the reverse osmosis membrane material. The reverse osmosis membrane material F enters the tape sticking mechanism 4 through the conveying mechanism. The sucker lifting mechanism 412 drives the sucker 411 to rise and contact the lower surface of the reverse osmosis membrane material F. The sucker 411 adsorbs the reverse osmosis membrane material F to make the production neater; then the tape flat sticking mechanism 42 sticks the tape on the upper surface of the reverse osmosis membrane material F.

[0055] (2) The reverse osmosis membrane material F after the tape is pasted enters the reverse osmosis membrane material platform 51 through the conveying mechanism. At this time, the membrane material lifting mechanism 54 is in the low position, and the inner top plate 544 is in the horizontal position, so that the clamping opening of the membrane material clamp faces the reverse osmosis membrane material F, that is, the two clamping plates 547 on the air claw 546 are arranged vertically. The front part of the reverse osmosis membrane material F enters the clamping opening of the membrane material clamp horizontally after passing through the turning roller 511, that is, between the two clamping plates 547. At this time, the front part of the reverse osmosis membrane material F is still horizontal to ensure the flatness of the membrane material. The air claw 546 acts, and the clamping plate 547 clamps and fixes the front part of the reverse osmosis membrane material F. Then the flipping mechanism 545 acts to drive the inner top plate 544 to flip upward and be in the vertical position. At the same time, the membrane material lifting mechanism 54 drives the clamping device to rise, and the clamping device drives the reverse osmosis membrane material F to rise. The rising reverse osmosis membrane material F is in a vertical state, which is convenient for the insertion of the flow guiding net cloth D. At the same time, the front part of the reverse osmosis membrane material F clamped by the membrane material clamp is also vertical to ensure the flatness of the membrane material.

[0056] At the same time, the flow guiding net cloth reel on the flow guiding net cloth opening mechanism 2 of the flow guiding net cloth unwinds, and the flow guiding net cloth D enters the flow guiding net cloth platform 52 through the conveying mechanism; see Figure 9, after the handling manipulator 6 clamps both sides of the front end of the diversion net cloth D and moves forward, it inserts the front end of the diversion net cloth D onto the reverse osmosis membrane material F lifted by the membrane material lifting mechanism 54, so that the upper and lower surfaces of the front end of the diversion net cloth D are superposed with the reverse osmosis membrane material F; the handling manipulator 6 continues to hold the diversion net cloth D and moves forward, and passes the superposed part of the diversion net cloth D and the reverse osmosis membrane material F through the pressing roller mechanism, that is, between the upper pressing roller 55 and the lower pressing roller 56. The upper and lower layers of the reverse osmosis membrane material F of the superposed part are respectively closely attached to the upper pressing roller 55 and the lower pressing roller 56; after passing through the upper pressing roller 55 and the lower pressing roller 56, the handling manipulator 6 continues to hold the diversion net cloth D and moves forward, and transports the superposed part of the diversion net cloth D and the reverse osmosis membrane material F into the superposition fixture 57. The superposition fixture 57 clamps the superposed part for fixation, and at the same time, the superposition fixture 57 flattens the superposed part; the handling manipulator 6 releases the diversion net cloth D, then clamps both sides of the superposed part, the superposition fixture 57 releases the superposed part, and the handling manipulator 6 drives the superposed part forward to the gluing platform 7. At the same time, the membrane material lifting mechanism 54 drives the reverse osmosis membrane material F to descend. During the process of the handling manipulator 6 clamping the superposed part and moving forward, through the pressure action of the upper pressing roller 55 and the lower pressing roller 56, the upper and lower layers of the reverse osmosis membrane material F are tightly pressed on the upper and lower surfaces of the diversion net cloth D, and the tape on the reverse osmosis membrane material F is bonded to the diversion net cloth D, so that the reverse osmosis membrane material F and the diversion net cloth D are tightly bonded and fixed to form the first membrane material; after the first membrane material reaches the set length dimension, the cutting film mechanisms 53 on the reverse osmosis membrane material platform 51 and the diversion net cloth platform 52 respectively cut off the reverse osmosis membrane material F and the diversion net cloth D, and then the handling manipulator 6 spreads the first membrane material flat on the gluing platform 7; the membrane material press 71 presses and fixes the first membrane material, and the gluing manipulator 11 applies glue to the first membrane material on the gluing platform 7.

[0057] When the cutting film mechanism 53 cuts, the pressing plate cylinder 534 drives the pressing plate 535 to move downward and press on the reverse osmosis membrane material F or the diversion net cloth D to fix the reverse osmosis membrane material F or the diversion net cloth D, and then the cutter cylinder 532 drives the cutter 533 to move horizontally, and the cutter 533 cuts the reverse osmosis membrane material F or the diversion net cloth D.

[0058] (3). For the semi-finished reverse osmosis membrane element produced, its inlet spacer is in an unfolded state on the semi-finished product. The handling manipulator 6 puts the semi-finished reverse osmosis membrane element on the shelf into the film winding machine 91, and at the same time puts the unfolded inlet spacer on the shelf 92; the rubbing film pressing plate rotating mechanism 97 drives the rubbing film pressing plate 96 to rotate and presses the rubbing film pressing plate 96 on the inlet spacer, and its function is to ensure that the inlet spacer does not move randomly during the film rubbing process, which is convenient for the smooth progress of the film picking action.

[0059] (4) The handling manipulator 6 spreads the first coated film material flat on the moving pallet 81, and then continues to move forward with the first film material. After the front part of the first film material crosses the moving pallet 81, it is spread on the fixed pallet 82, and the rear part of the first film material still remains on the moving pallet 81; the handling manipulator 6 releases the first film material, and the pallet moving mechanism 83 drives the moving pallet 81 to move backward, and the rear part of the first film material is gradually spread on the fixed pallet 82 until the entire first film material is spread on the fixed pallet 82.

[0060] (5) The film rubbing roller moving mechanism 95 drives the film rubbing roller 93 and the film rubbing roller driving mechanism 94 to move backward. The film rubbing roller 93 presses on the unfolded water inlet partition net, and the film rubbing roller rotating mechanism 94 drives the film rubbing roller 93 to rotate. The film rubbing roller 93 rubs the water inlet partition net upward, so that a space with a certain gap is formed between the water inlet partition net and the support frame 92 for the clamping operation of the handling manipulator 6, without damaging the film structure. Without this space, the handling manipulator 6 may damage the water inlet partition net during the clamping process.

[0061] After the handling manipulator 6 extends into the space between the water inlet partition net and the support frame 92 and clamps the water inlet partition net, the film rubbing roller moving mechanism 95 drives the film rubbing roller 93 and the film rubbing roller driving mechanism 94 to reset, and the film rubbing roller 93 leaves the water inlet partition net. At the same time, the film rubbing pressing plate rotating mechanism 97 drives the film rubbing pressing plate 96 to rotate, and the film rubbing pressing plate 96 leaves the water inlet partition net; the handling manipulator 6 spreads the water inlet partition net flat on the first film material on the fixed pallet 82, and the water inlet partition net and the first film material are bonded and fixed together to form the second film material.
