Description

Technical Field

[0001] This invention relates to the field of industrial wastewater and seawater desalination filter technology, specifically to a fully automated industrial membrane element preparation system and its usage method. Background Technology

[0002] With increasingly fierce competition in the water treatment market, in order to meet customers' throughput requirements, an industrial membrane element based on the mixing and rolling of two diaphragm sheets in a certain proportion has emerged.

[0003] Currently, industrial membrane module preparation is mostly done manually. The main steps of this method are as follows: Step 1: Mechanically cut the concentrated mesh and pure mesh membrane sheets, and manually transfer them to the folding area; Step 2: Manually cut different types of diaphragm sheets and fold them according to size; Step 3: Manually open the folded membrane sheets and place the concentrated mesh inside; Step 4: Manually mix and match the diaphragm sheets in an orderly manner according to process requirements, storing each membrane element in a separate set to avoid mixing; Step 5: Manually weld the pure mesh, welding together the required number of pure meshes for one membrane element at a certain dimensional distance; Step 6: When manually winding the membrane, manually place the diaphragm sheet assemblies into the pure mesh welding assemblies in the order above. After each diaphragm assembly is positioned, apply adhesive, and after winding the membrane, wrap it with tape to secure it in shape.

[0004] Industrial membrane sheets are generally quite large when unfolded, and the original manual folding method cannot meet the needs of mass production. At the same time, the original manual folding method affects the welding of the mesh, which is prone to misalignment in the subsequent rolling process and is inefficient. More importantly, in order to meet the customer's specified requirements for the water flow rate and desalination rate of the membrane element, it is necessary to mix and match different membrane materials as needed.

[0005] Therefore, how to automate the production of industrial membrane elements to meet the personalized needs of membrane elements has become an urgent problem to be solved. Summary of the Invention

[0006] The present invention aims to provide a fully automated industrial membrane element preparation system and its usage method to solve the above problems.

[0007] The technical solution of this invention is: a fully automated industrial membrane element preparation system, comprising a diaphragm overlay assembly preparation unit one, a diaphragm overlay assembly preparation unit two, a diaphragm overlay assembly mixing and conveying unit, a pure water mesh cutting and welding unit, a central tube feeding unit, a membrane element mixing and winding forming unit, and a membrane element unloading unit; wherein,

[0008] The diaphragm lap welding assembly preparation unit one and the diaphragm lap welding assembly preparation unit two are used to prepare different diaphragm lap welding assemblies one and two, respectively; the diaphragm materials selected in the preparation of the diaphragm lap welding assemblies in the diaphragm lap welding assembly preparation unit one and the diaphragm lap welding assembly preparation unit two are different; the mesh fabric used in the diaphragm lap welding assembly preparation unit one and the diaphragm lap welding assembly preparation unit two is the concentrate mesh fabric;

[0009] The diaphragm stacked assembly mixing and conveying unit is used to mix and convey the diaphragm stacked assemblies prepared by diaphragm stacked assembly preparation unit one and diaphragm stacked assembly preparation unit two.

[0010] The pure water mesh cutting and welding unit is used to cut and weld pure water mesh to form pure water mesh assemblies.

[0011] The central tube feeding unit is used to pick up and position the central tube, which facilitates the gripping of the central tube by the membrane element mixing and winding forming unit.

[0012] The membrane element mixing and winding forming unit is used to mix and wind different diaphragm stacking components conveyed by the diaphragm stacking and conveying unit, pure water mesh components cut and welded by the mesh cutting and welding unit, and central tubes picked up by the central tube feeding unit to form membrane elements.

[0013] The film element unloading unit is used to unload the film elements prepared by the film element mixing and winding forming unit.

[0014] Preferably, the diaphragm stacking assembly preparation unit includes a concentrate mesh feeding and storage mechanism, a concentrate mesh picking and conveying mechanism, a concentrate mesh cutting mechanism, a linear module robot, a diaphragm feeding and storage mechanism, a stacking worktable, a diaphragm picking and folding mechanism, a diaphragm cutting mechanism, an ultrasonic welding mechanism, and a diaphragm assembly unloading mechanism.

[0015] In the diaphragm stacking assembly preparation unit one, the diaphragm used in each mechanism is diaphragm material one;

[0016] The concentrated water mesh feeding and storage mechanism is mainly used for feeding and storing concentrated water mesh. The feeding function has a correction function, and the storage function is to ensure stable tension when feeding material outward.

[0017] The concentrated water mesh material conveying mechanism is responsible for unfolding the concentrated water mesh and pulling it out a certain distance, cooperating with the concentrated water mesh cutting mechanism to cut it to a fixed length, and then sending it to the transfer station.

[0018] The concentrated water mesh cutting mechanism is responsible for cutting the concentrated water mesh. It drives the blade to cut the concentrated water mesh on the cutting board through the synchronous belt transmission system.

[0019] The linear module robot arm uses grippers to pick up the cut concentrate mesh at the transfer station, and then uses linear module movement to send it to the stacking worktable to stack the concentrate mesh and diaphragm.

[0020] The diaphragm feeding and storage mechanism is mainly used for feeding and storing diaphragm materials. The feeding mechanism has a correction function, and the storage mechanism is used to ensure stable feeding of materials under low tension.

[0021] The stacking workbench is constructed by placing a layer of concentrate mesh and a layer of diaphragm, and repeating this process. This process achieves overlapping and pressing of the concentrate mesh and diaphragm at this workstation. The width of the diaphragm and the concentrate mesh is the same, but the length of the diaphragm is twice the length of the concentrate mesh. This ensures that the concentrate mesh and diaphragm overlap by half their size, making it easier to grab and transport them to the next workstation.

[0022] The diaphragm material handling and folding mechanism includes a linear motion module, a flipping cylinder, and a pneumatic gripper, used for transferring and folding the diaphragm and concentrate mesh. The mechanism uses the pneumatic gripper to pick up the stacked diaphragm and concentrate mesh, sequentially passing through the cutting station, folding station, welding station, and transfer station. The cutting station corresponds to the cutting mechanism; the folding station corresponds to the flipping cylinder of the folding mechanism; the welding station corresponds to the ultrasonic welding mechanism; and the transfer station corresponds to the linear motion module of the folding mechanism. The pneumatic gripper is used to pick up the stacked diaphragm and concentrate mesh; the flipping cylinder is used to fold the portion of the diaphragm that is not stacked with the concentrate mesh after cutting; and the linear motion module is used to transport the stacked diaphragm and concentrate mesh sequentially to the cutting station, folding station, welding station, and finally to the transfer station.

[0023] The diaphragm cutting mechanism is responsible for cutting the diaphragm. It uses a synchronous belt drive system to drive the blades to cut the stacked concentrated water mesh and diaphragm on the cutting board.

[0024] The ultrasonic welding mechanism is responsible for welding the pre-fabricated components of the concentrated water mesh and the diaphragm together at the welding station. Specifically, at this stage, only the diaphragm is folded, while the mesh is not folded. The mesh is sandwiched in the middle of the diaphragm, forming a three-layer structure. Welding is to weld these three layers together.

[0025] The diaphragm module unloading mechanism is responsible for grabbing the prepared diaphragm stacked assembly at the transfer station and sending it to the unloading station, which facilitates the grabbing of the diaphragm stacked assembly mixing and conveying unit.

[0026] Preferably, the second diaphragm stacking assembly preparation unit specifically includes a second diaphragm feeding and storage mechanism, a second diaphragm feeding and conveying mechanism, a second diaphragm cutting mechanism, a second diaphragm end sealing mechanism, a second concentrated water mesh feeding and storage mechanism, a second concentrated water mesh feeding and conveying mechanism, a second concentrated water mesh cutting mechanism, a concentrated water mesh lowering and folding mechanism, a diaphragm welding folding and heating mechanism, and a second diaphragm assembly unloading mechanism.

[0027] In particular, the diaphragm used in each mechanism of the diaphragm stacked assembly preparation unit two is diaphragm material two;

[0028] The second diaphragm feeding and storage mechanism is mainly used for feeding and storing diaphragm material. The feeding mechanism has a correction function; the storage mechanism is used to feed material outward to ensure that the tension value does not exceed the set value.

[0029] The diaphragm material feeding and conveying mechanism is responsible for unfolding the diaphragm and pulling it out a certain distance, and cooperating with the second diaphragm cutting mechanism to achieve fixed-length cutting; the cut diaphragm material is sent to the end sealing position and cooperated with the diaphragm end sealing mechanism to achieve end sealing, and finally sent to the diaphragm folding position and cooperated with the concentrate mesh feeding and folding mechanism to achieve folding of the diaphragm material and sandwich the concentrate mesh in the middle;

[0030] The second diaphragm cutting mechanism is responsible for cutting the diaphragm;

[0031] After the diaphragm is cut, the diaphragm end-sealing mechanism performs thermoplastic sealing on both sides of the cut diaphragm, so that the diaphragm substrate and the coated film layer on the diaphragm are thermally bonded together.

[0032] The second feeding and storage mechanism for concentrated water mesh is mainly used for feeding and storing concentrated water mesh. The feeding mechanism has a correction function; the storage mechanism is used to ensure stable feeding under low tension.

[0033] The second concentrated water mesh conveying mechanism is responsible for unfolding and pulling out the concentrated water mesh a certain distance, cooperating with the second concentrated water mesh cutting mechanism to achieve fixed-length cutting, and then sending it to the transfer station;

[0034] The second concentrated water mesh cutting mechanism is responsible for cutting the concentrated water mesh;

[0035] The concentrate mesh feeding and folding mechanism picks up the cut concentrate mesh and conveys it downwards to the center of the flattened diaphragm via a flipping cylinder and guide rail. They then move downwards together, completing the diaphragm folding and assembly with the concentrate mesh. This achieves the concentrate mesh being sandwiched within the folded diaphragm, i.e., the diaphragm wraps around the concentrate mesh. Specifically, the concentrate mesh is half the size of the diaphragm and positioned directly above it. After cutting, the mesh is fed downwards and folded by the concentrate mesh feeding and folding mechanism, specifically by the grippers of the flipping cylinder picking up the concentrate mesh. The cylinder rotates, causing the concentrate mesh to move downwards. Then, through a downward linear conveying mechanism, the concentrate mesh is delivered to the bottom, changing from a horizontal position to an upright position. The diaphragm is now laid flat below, with the bottom edge of the concentrate mesh aligned with the center of the diaphragm. Finally, the concentrate mesh continues to move downwards through a folding mechanism. At this point, the concentrate mesh and the diaphragm move downwards together along a gap, and the downward movement of the diaphragm achieves a folding function, also clamping the mesh in the middle of the diaphragm.

[0036] The concentrated water mesh feeding and folding mechanism first connects the flipping cylinder gripper with the horizontal traction gripper of the second concentrated water mesh picking and conveying mechanism. After clamping the concentrated water mesh that has been horizontally conveyed to the position, it flips and conveys it vertically downward, so that the concentrated water mesh can be accurately conveyed to the middle seam of the diaphragm and connect with the diaphragm welding, folding and heating mechanism.

[0037] The diaphragm welding, folding, and heating mechanism is responsible for welding the folded diaphragm components together using an ultrasonic welding gun. Because the diaphragm is relatively thick, the creases after folding are not very obvious. Therefore, during welding, the diaphragm welding, folding, and heating mechanism heats and irons the creases in the folding seam to solidify them. The concentrate mesh is sandwiched in the middle of the diaphragm. The diaphragm welding, folding, and heating mechanism welds the two sides of the diaphragm width together. In other words, the diaphragm and the concentrate mesh are ultrasonically welded on both sides to form weld points, making them a strong and stable membrane mesh component.

[0038] The second diaphragm module unloading mechanism is responsible for grabbing the prepared diaphragm stacked welding assembly and sending it to the unloading station, which facilitates the grabbing of the diaphragm stacked welding assembly mixing and conveying unit. The second diaphragm module unloading mechanism includes a lifting servo module and a rotary cylinder, which are respectively connected to the grippers of the concentrate mesh feeding and folding mechanism to grab the welded diaphragm stacked welding assembly and move it up and down and flip it.

[0039] The second diaphragm assembly unloading mechanism uses a synchronous belt pulley drive system to perform linear traction along the guide rails on both sides, thereby enabling the grippers to pull and transport the diaphragm stacked assembly to the unloading and turnover station.

[0040] Preferably, the diaphragm stacking assembly mixing and conveying unit specifically includes a guide rail screw drive mechanism, a material handling frame, and a gripping clamp;

[0041] The guide rail screw drive mechanism consists of two sets of guide rails and a set of motor screw drive components, which drive the diaphragm stacked welding assembly mixing and conveying unit to move back and forth linearly between the diaphragm stacked welding assembly preparation unit one and the diaphragm stacked welding assembly preparation unit two.

[0042] The material handling frame consists of a square steel tube assembly frame and a cylinder slide rail assembly, which is used to drive the gripper's up-down and back-forward movement. The up-down movement of the gripper is used to connect and grip the diaphragm stacked assemblies of different heights on the turnover station. The back-forward movement of the gripper is the movement to send the gripped diaphragm stacked assemblies to the film winding station near the membrane element mixing and forming unit, so that the film winding station's grippers can grip the film.

[0043] The gripper consists of a gripper opening and closing cylinder assembly, used to grip the prepared diaphragm stacked assembly one and diaphragm stacked assembly two.

[0044] Preferably, the pure water mesh cutting and welding unit specifically includes a pure water mesh unwinding and storage mechanism, a pure water mesh material conveying mechanism, a pure water mesh cutting mechanism, a pure water mesh welding mechanism, and a pure water mesh and central tube welding mechanism;

[0045] The pure water mesh unwinding and storage mechanism actively unwinds the pure water mesh material mounted on the air shaft by rotating it with a motor; the storage is achieved by the pure water mesh hanging down under the motor and triggering the storage induction switch, so that the tension of the pure water mesh is very small.

[0046] The pure water mesh material conveying mechanism is controlled by a synchronous belt pulley transmission system and a lifting servo module to perform horizontal linear traction, moving up and down to achieve the specified traction action of the gripper holding the pure water mesh and delivering it to the designated cutting position, welding position and welding pipe position;

[0047] The pure water mesh cutting mechanism is responsible for cutting the pure water mesh; the pure water mesh is pressed by the pure water mesh pressing assembly, that is, the lifting cylinder, the translation cylinder and the motor in the cutting mechanism drive the cutter to rotate at high speed to cut the pure water mesh.

[0048] The pure water mesh welding mechanism consists of an ultrasonic welding component and a pure water mesh pressure plate component. After the pure water mesh pressure plate component presses the pure water mesh, the welding pressing cylinder of the ultrasonic welding component moves downward to perform ultrasonic welding. After the weld is completed, the welding pressing cylinder is lifted. After the welding is completed, the pure water mesh material picking and conveying mechanism pulls the pure water mesh welding component to the pure water mesh and central tube welding mechanism.

[0049] The pure water mesh and central tube welding mechanism welds the pure water mesh welding assembly to the central tube to form the pure water mesh and central tube welding assembly.

[0050] Preferably, the central tube feeding unit specifically includes a pin clamping assembly, a pushing assembly, a hole positioning assembly, and a central tube storage bin; the central tube feeding unit is used to pick up the central tube and position it in a precise location for easy gripping by the gripping robot.

[0051] Preferably, the membrane element mixing and forming unit specifically includes a film winding station one, a film winding station two, a flattening and gripping robot, and a glue-applying robot; the film winding station two has the same structure as the film winding station one;

[0052] The film winding station includes a film winding pin assembly, a mesh spreading platform, an adhesive coating platform, a pure water mesh tensioning assembly, a diaphragm traction assembly, and an adhesive tape winding assembly;

[0053] The flattening and gripping robot picks up the welded pure water mesh and the central tube welding assembly and places them into the film rolling station. First, the pure water mesh is laid out on the mesh laying platform, and the central tube is placed on the film rolling pin assembly. The two ends of the central tube are fixed and clamped by the film rolling pin assembly. The flattening and gripping robot picks up the top first pure water mesh, flips it onto the glue coating platform, and the pure water mesh tensioning assembly on the glue coating platform clamps the first pure water mesh, applies a certain tension, and tightens it.

[0054] The diaphragm traction assembly docks with the diaphragm stacking assembly mixing and conveying unit, gripping the diaphragm stacking assembly for diaphragm insertion. This involves placing the diaphragm stacking assembly on top of the first pure water mesh and delivering it to the root of the central tube. After the diaphragm is in place, the grippers of the traction assembly release the diaphragm stacking assembly, returning to their original position, and docking with the diaphragm stacking assembly mixing and conveying unit again. The glue-applying robot then begins applying glue, applying it to the newly inserted diaphragm stacking assembly on the glue-applying platform. Glue is applied along the perimeter of the diaphragm stacking assembly, leaving the edge at the root of the central tube uncoated. The other three edges are coated with a continuous, sealed layer of glue, ensuring the diaphragm stacking assembly connects with the second pure water mesh that is about to be flipped over. The three edges of the fabric are glued together. Then, the flattening and gripping robot continues to grip the second pure water mesh fabric on the mesh fabric laying platform and flips it to the gluing platform to achieve adhesion between the three edges of the second pure water mesh fabric and the membrane stacking assembly. This process is repeated. After all the pure water mesh fabrics and the membrane stacking assembly are glued together, the membrane is rolled up. During the membrane rolling process, the pure water mesh fabric tensioning assembly on the gluing platform continuously clamps the first pure water mesh fabric and maintains a certain tension, which is less than the force of the membrane rolling. Finally, it moves forward with the membrane rolling and gradually approaches the central tube. After the membrane rolling is completed, the tape wrapping assembly automatically applies, wraps, and cuts the tape. Finally, the flattening and gripping robot transports and grips the prepared membrane element product off the production line.

[0055] The flat gripping robot is a six-degree-of-freedom robot, mainly responsible for gripping the central tube for feeding, gripping the pure water mesh and the welding assembly of the central tube for feeding, flipping and flattening the pure water mesh at the film winding station, and gripping and unloading the membrane element after the film winding is completed to the membrane element unloading trolley.

[0056] The glue-applying robot is a six-degree-of-freedom robot, mainly responsible for applying glue between the membrane layers. A square membrane is coated with a fixed amount of glue with three closed sides, and after drying, it forms a "bag". The opening of the bag is aligned with the central tube. The pure water filtered through the bag flows into the central tube through multiple rows of small holes.

[0057] Preferably, the membrane element unloading unit specifically includes a membrane element tilting storage rack and a membrane element unloading trolley. The prepared membrane elements are rolled out of the membrane element unloading trolley by the membrane element tilting storage rack, which facilitates inspection and handling by personnel in a safe area outside the fence.

[0058] A method of using a fully automated industrial membrane element fabrication system, comprising:

[0059] Step 1: Fabrication of the diaphragm stacked assembly;

[0060] Step 2: Mixing and conveying of diaphragm stacked assembly;

[0061] Step 3: Cutting and welding the pure water mesh;

[0062] Step 4: Feeding the central tube and welding the mesh to the central tube;

[0063] Step 5: Membrane element mixing and winding;

[0064] Step 6: Unloading the film winding components.

[0065] Preferably, in step one, diaphragm lap welding assembly preparation unit one and diaphragm lap welding assembly preparation unit two are respectively used to prepare different diaphragm lap welding assemblies one and two; wherein,

[0066] The specific usage method of the first diaphragm cladding assembly fabrication unit includes:

[0067] S11, the concentrated water mesh is manually fed into the concentrated water mesh unloading and storage mechanism 1, and the diaphragm material is fed into the diaphragm unwinding and storage mechanism 1. After pressing the start button, the mesh material picking and conveying mechanism 1 pulls out the concentrated water mesh and cuts it by the mesh cutting mechanism 1. Then, the linear module robot grabs it and sends it to the stacking worktable.

[0068] S12, while the button is pressed, the gripper of the diaphragm material picking and folding mechanism pulls the diaphragm material one onto the stacking worktable, realizing half of the concentrate mesh and diaphragm material one being stacked, with the concentrate mesh on top of the diaphragm material one; the gripper of the diaphragm material picking and folding mechanism releases and picks up the concentrate mesh and diaphragm material a second time, and sends the diaphragm to the cutting position through the linear module of the diaphragm material picking and folding mechanism, where the diaphragm material one is cut by the diaphragm cutting mechanism one;

[0069] S13, after cutting, the diaphragm material one is folded by the flipping cylinder and linear module of the diaphragm material picking and folding mechanism, and the concentrate mesh is sandwiched in the middle of the diaphragm material one and sent to the welding position. The ultrasonic welding mechanism realizes the three-layer welding of the diaphragm and the concentrate mesh. The diaphragm material picking and folding mechanism sends the welded diaphragm stacked assembly one to the transfer station. The diaphragm assembly unloading mechanism one is responsible for grabbing the prepared diaphragm stacked assembly one at the transfer station and sending it to the unloading station, which facilitates the grabbing of the diaphragm stacked assembly mixing and conveying unit.

[0070] The specific usage method of the second diaphragm stacked assembly preparation unit includes:

[0071] S21, the concentrated water mesh is manually fed into the concentrated water mesh feeding and storage mechanism two, and the diaphragm material two is fed into the diaphragm unwinding and storage mechanism two. After pressing the start button, the mesh feeding and conveying mechanism two pulls out the concentrated water mesh, which is then cut by the mesh cutting mechanism two and picked up by the mesh feeding and conveying mechanism two and sent to the docking position with the mesh unloading and folding mechanism two. The flipping cylinder gripper of the mesh unloading and folding mechanism two picks up the concentrated water mesh at the docking position and conveys it downward to the folding position of the diaphragm through the flipping cylinder and guide rail of the mesh unloading and folding mechanism two, that is, to the center of the flat diaphragm.

[0072] S22, while the button is pressed, the grippers of the diaphragm material feeding and conveying mechanism pull out the second diaphragm material and cut it by the second diaphragm cutting mechanism;

[0073] S23, after cutting, it is sent to the end sealing position by the diaphragm material feeding and conveying mechanism, and the diaphragm end sealing mechanism performs heat sealing on both sides of the diaphragm cut, so that the diaphragm substrate and the coating film layer on the diaphragm are heat-fused together.

[0074] S24, the diaphragm after end sealing is sent to the folding position by the diaphragm feeding and conveying mechanism. At the folding position, the concentrated water mesh fabric is fed from top to bottom by the mesh fabric feeding and folding mechanism 2. The mesh fabric feeding and folding mechanism 2 moves the two together along a gap and moves down a distance to complete the diaphragm center folding and assembly with the concentrated water mesh fabric. The assembly effect is that the concentrated water mesh fabric is sandwiched in the folded diaphragm, that is, the diaphragm wraps the concentrated water mesh fabric; and it is connected to the diaphragm welding folding heating mechanism.

[0075] S25, the diaphragm welding folding heating mechanism is responsible for welding the three layers of the folded diaphragm assembly together using an ultrasonic welding gun. Because the second diaphragm material is relatively thick, the creases are not very obvious after folding. Therefore, during welding, the diaphragm welding folding heating mechanism heats and irons the creases in the folding seam to solidify the creases.

[0076] S26, after the diaphragm assembly is welded, the lifting servo module of the second diaphragm assembly unloading mechanism will send the gripper of the rotary cylinder upward to grab the diaphragm welding assembly. After grabbing, the rotary cylinder will descend and rotate. Through the synchronous belt pulley transmission system, it will be pulled linearly along the guide rails on both sides, thereby realizing the traction and transportation of the diaphragm stacked welding assembly grabbed by the gripper to the unloading and turnover station, which is convenient for the diaphragm stacked welding assembly mixed picking and conveying unit to grab.

[0077] Step two, mixing and conveying of diaphragm stacked assembly; specific usage methods include:

[0078] The guide rail screw drive mechanism drives the material handling frame and the gripping clamp to move back and forth linearly between the diaphragm laminated assembly preparation unit one and the diaphragm laminated assembly preparation unit two; it is used to mix and transport the diaphragm laminated assemblies prepared by the diaphragm laminated assembly preparation unit one and the diaphragm laminated assembly preparation unit two.

[0079] Step 3: Cutting and welding the pure water mesh; specific usage methods include:

[0080] After the pure water mesh is manually fed into the mesh unwinding and storage mechanism, the start button is pressed. The mesh material conveying mechanism then pulls out the concentrated water mesh, which is cut by the mesh cutting mechanism. The mesh material conveying mechanism then sends the concentrated water mesh to the welding position, where the pure water mesh welding mechanism welds the pure water mesh together. After the pure water mesh is welded according to a certain quantity and requirements, the mesh material conveying mechanism sends the welded pure water mesh to the area below the pure water mesh and central tube welding mechanism, waiting to be welded to the central tube.

[0081] Step four: feeding the central tube and welding the mesh to the central tube; specific usage methods include:

[0082] After manually loading the pure water mesh fabric into the pure water mesh fabric unwinding and storage mechanism, pressing the start button activates the pure water mesh fabric picking and conveying mechanism. The pure water mesh fabric is then pulled out by the pure water mesh fabric cutting mechanism, cut, and then pulled again by the picking and conveying mechanism to the pure water mesh fabric welding mechanism. The clamps are then released to place the pure water mesh fabric. The picking and conveying mechanism then returns to the fabric-pulling position, and the pure water mesh fabric is pulled out again for cutting by the pure water mesh fabric cutting mechanism and placed on the first layer of pure water mesh fabric. At this point, the picking and conveying mechanism returns to the fabric-pulling position. The water mesh welding mechanism starts welding, and the work is repeated in this cycle. The pure water mesh will be welded together in a progressive order. Repeat the required number of pure water mesh pages. After all the pure water mesh is welded, the pure water mesh material picking and conveying mechanism will pull the pure water mesh assembly to the pure water mesh and central tube welding mechanism. At this time, a flattening and gripping robot has already grabbed the central tube and fed it to the pure water mesh and central tube welding mechanism to carry out the welding of the bottom layer of pure water mesh and central tube. After the welding is completed, the flattening and gripping robot grabs the tube assembly to the membrane element mixing and winding forming unit.

[0083] Step 5: Membrane element mixing and winding; specific usage methods include:

[0084] The flattening and gripping robot picks up the welded pure water mesh and the central tube welding assembly and places them into the film rolling station. First, the pure water mesh is laid out on the mesh laying platform, and the central tube is placed on the film rolling pin assembly. The two ends of the central tube are fixed and clamped by the film rolling pin assembly. The flattening and gripping robot picks up the top first pure water mesh, flips it onto the glue coating platform, and the pure water mesh tensioning assembly on the glue coating platform clamps the first pure water mesh, applies a certain tension, and tightens it.

[0085] The diaphragm traction assembly at the membrane winding station docks with the diaphragm overlapping assembly mixing and conveying unit, gripping the diaphragm overlapping assembly for diaphragm insertion. This involves placing the diaphragm overlapping assembly on top of the first pure water mesh and delivering it to the root of the central tube. After the diaphragm is in place, the membrane traction assembly's grippers release the diaphragm overlapping assembly, returning to its original position, and docking with the diaphragm overlapping assembly mixing and conveying unit again. The glue-applying robot's glue-applying unit then applies glue to the newly inserted diaphragm overlapping assembly on the glue-applying platform, applying glue along the perimeter of the assembly. The edge inserted at the root of the central tube is left unapplied, while the other three edges are coated with a continuous, sealed glue, ensuring the diaphragm overlapping assembly connects with the second pure water mesh that is about to be flipped over. The three edges of the water mesh fabric are glued together. Then, the flattening and gripping robot continues to grip the second pure water mesh fabric on the mesh fabric laying platform and flips it to the glue coating platform to achieve the bonding of the three edges of the second pure water mesh fabric with the membrane stacking assembly. This process is repeated. After all the pure water mesh fabrics and the membrane stacking assembly are bonded, the membrane is rolled. During the membrane rolling process, the pure water mesh fabric tensioning assembly on the glue coating platform continuously clamps the first pure water mesh fabric and maintains a certain tension, which is less than the force of the membrane rolling. Finally, it moves forward with the membrane rolling and gradually approaches the central tube. After the membrane rolling is completed, the tape wrapping assembly automatically applies, wraps, and cuts the tape. Finally, the flattening and gripping robot transports and grips the prepared membrane element product off the production line.

[0086] Step six, unloading the film winding element; specific usage methods include:

[0087] The membrane element unloading unit specifically includes a membrane element tilting storage rack and a membrane element unloading trolley. The membrane element unloading trolley is placed at the opening of the safety enclosure fence and is used to grip the prepared membrane elements stored by the robot. The membrane elements are then rolled out of the trolley via the membrane element tilting storage rack, making it convenient for personnel to inspect and move them in a safe area outside the fence.

[0088] The beneficial effects of this invention are as follows:

[0102] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. The embodiments of the present invention are not limited thereto.

[0103] Example 1

[0104] like Figure 1 As shown, a fully automated industrial membrane element preparation system includes: a diaphragm overlay assembly preparation unit 1; a diaphragm overlay assembly preparation unit 2; a diaphragm overlay assembly mixing and conveying unit 3; a pure water mesh cutting and welding unit 4; a central tube feeding unit 5; a membrane element mixing and winding forming unit 6; and a membrane element unloading unit 7; wherein,

[0105] The diaphragm lap welding assembly preparation unit 1 and the diaphragm lap welding assembly preparation unit 2 are used to prepare different diaphragm lap welding assemblies 1 and 2, respectively; the diaphragm materials selected by the diaphragm lap welding assembly preparation unit 1 and the diaphragm lap welding assembly preparation unit 2 are different when preparing the diaphragm lap welding assemblies; the mesh fabric used by the diaphragm lap welding assembly preparation unit 1 and the diaphragm lap welding assembly preparation unit 2 is the concentrate mesh fabric;

[0106] The diaphragm stacked assembly mixing and conveying unit 3 is used to mix and convey the diaphragm stacked assemblies prepared by diaphragm stacked assembly preparation unit 1 and diaphragm stacked assembly preparation unit 2.

[0107] The pure water mesh cutting and welding unit 4 is used to cut and weld the pure water mesh to form a pure water mesh assembly.

[0108] The central tube feeding unit 5 is used to pick up the central tube and position it, which facilitates the gripping of the central tube by the membrane element mixing and winding forming unit 6.

[0109] The membrane element mixing and winding forming unit 6 is used to mix and wind different diaphragm stacking components conveyed by the diaphragm stacking assembly mixing and conveying unit 3, pure water mesh assembly cut and welded by the mesh cutting and welding unit 4, and central tube picked up by the central tube feeding unit 5 to form membrane elements.

[0110] The film element unloading unit 7 is used to unload the film elements prepared by the film element winding and forming unit 6.

[0111] like Figure 2 As shown, the diaphragm stacking assembly preparation unit 1 specifically includes a concentrate mesh feeding and storage mechanism 101, a concentrate mesh picking and conveying mechanism 102, a concentrate mesh cutting mechanism 103, a linear module robot 104, a diaphragm feeding and storage mechanism 105, a stacking worktable 106, a diaphragm picking and folding mechanism 107, a diaphragm cutting mechanism 108, an ultrasonic welding mechanism 109, and a diaphragm assembly unloading mechanism 110.

[0112] Among them, the diaphragm used in each mechanism of the diaphragm stacking assembly preparation unit 1 is diaphragm material 1;

[0113] The concentrated water mesh feeding and storage mechanism 101 is mainly used for feeding and storing concentrated water mesh. The feeding function has a correction function, and the storage function is to ensure stable tension when feeding material outward.

[0114] The concentrate mesh material conveying mechanism 102 is responsible for unfolding the concentrate mesh and pulling it out a certain distance, cooperating with the concentrate mesh cutting mechanism 103 to cut it to a fixed length, and then sending it to the transfer station.

[0115] The concentrated water mesh cutting mechanism 103 is responsible for cutting the concentrated water mesh. It drives the blade to cut the concentrated water mesh on the cutting board through the synchronous belt transmission system.

[0116] The linear module robot 104 uses grippers to pick up the cut concentrate mesh at the transfer station and sends it to the stacking worktable 106 through linear module movement to achieve the stacking of concentrate mesh and diaphragm.

[0117] The diaphragm feeding and storage mechanism 105 is mainly used for feeding and storing diaphragm materials. The feeding mechanism has a correction function, and the storage mechanism is used to ensure stable feeding of materials under low tension.

[0118] The stacking worktable 106 uses a method of placing one layer of concentrate mesh and one layer of diaphragm, and repeating this process to achieve overlapping and pressing of the concentrate mesh and diaphragm at this station. The width of the diaphragm and the concentrate mesh is the same, but the length of the diaphragm is twice the length of the concentrate mesh, so that the concentrate mesh and diaphragm overlap by half their size, which is convenient for subsequent grabbing and transportation to the next station.

[0119] The diaphragm material handling and folding mechanism 107 includes a linear motion module, a flipping cylinder, and a gripper, used for transferring and folding the diaphragm and concentrate mesh. The diaphragm material handling and folding mechanism 107 uses the gripper to pick up the stacked diaphragm and concentrate mesh, and passes them sequentially through the cutting station, folding station, welding station, and transfer station. The cutting station corresponds to the diaphragm cutting mechanism 108; the folding station corresponds to the flipping cylinder of the folding mechanism 107; the welding station corresponds to the ultrasonic welding mechanism 109; and the transfer station corresponds to the linear motion module of the folding mechanism 107. The gripper is used to pick up the stacked diaphragm and concentrate mesh; the flipping cylinder is used to fold the diaphragm that is not stacked with the concentrate mesh after cutting; and the linear motion module is used to transport the stacked diaphragm and concentrate mesh sequentially to the cutting station, folding station, welding station, and transfer station.

[0120] The diaphragm cutting mechanism 108 is responsible for cutting the diaphragm. It uses a synchronous belt drive system to drive the blades to cut the stacked concentrate mesh and diaphragm on the cutting board.

[0121] The ultrasonic welding mechanism 109 is responsible for welding the concentrated water mesh and the diaphragm folded prefabricated components together at the welding station. Specifically, at this time, since only the diaphragm is folded in the aforementioned stage and the mesh is not folded, the mesh is sandwiched in the middle of the diaphragm, forming a three-layer structure. Welding is to weld these three layers together.

[0122] The diaphragm module unloading mechanism 110 is responsible for grabbing the prepared diaphragm stacked assembly at the transfer station and sending it to the unloading station, which facilitates the grabbing of the diaphragm stacked assembly mixing and conveying unit 3.

[0123] like Figure 3As shown, the second diaphragm stacking assembly preparation unit 2 specifically includes a second diaphragm feeding and storage mechanism 201, a second diaphragm feeding and conveying mechanism 202, a second diaphragm cutting mechanism 203, a second diaphragm end sealing mechanism 204, a second diaphragm concentrate mesh feeding and storage mechanism 205, a second diaphragm concentrate mesh feeding and conveying mechanism 206, a second diaphragm concentrate mesh cutting mechanism 207, a second diaphragm concentrate mesh feeding and folding mechanism 208, a second diaphragm welding, folding and heating mechanism 209, and a second diaphragm assembly unloading mechanism 210.

[0124] Among them, the diaphragm used in each mechanism of the diaphragm stacking assembly preparation unit 2 is diaphragm material 2;

[0125] The diaphragm feeding and storage mechanism 201 is mainly used for feeding and storing diaphragm material. The feeding mechanism has a correction function; the storage mechanism is used to feed material outward to ensure that the tension value does not exceed the set value.

[0126] The diaphragm material feeding and conveying mechanism 202 is responsible for unfolding the diaphragm and pulling it out a certain distance, and cooperating with the diaphragm cutting mechanism 203 to achieve fixed-length cutting; the cut diaphragm material 2 is sent to the end sealing position to cooperate with the diaphragm end sealing mechanism 204 to achieve end sealing, and finally sent to the diaphragm folding position to cooperate with the concentrate mesh feeding and folding mechanism 208 to achieve folding of the diaphragm material 2 and sandwich the concentrate mesh in the middle;

[0127] The diaphragm cutting mechanism 203 is responsible for cutting the diaphragm;

[0128] After the diaphragm is cut, the diaphragm end sealing mechanism 204 performs thermoplastic sealing on both sides of the cut diaphragm, so that the membrane substrate and the coated film layer on the membrane are thermally bonded together.

[0129] The concentrate mesh feeding and storage mechanism 205 is mainly used for feeding and storing concentrate mesh. The feeding function has a deviation correction function; the storage function is to ensure stable feeding of material under low tension.

[0130] The concentrate mesh material conveying mechanism 206 is responsible for unfolding and pulling out the concentrate mesh a certain distance, cooperating with the concentrate mesh cutting mechanism 207 to perform fixed-length cutting, and then sending it to the transfer station;

[0131] The concentrated water mesh cutting mechanism 207 is responsible for cutting the concentrated water mesh;

[0132] The concentrate mesh feeding and folding mechanism 208 picks up the cut concentrate mesh and conveys it downwards to the center of the flat diaphragm via a flipping cylinder and guide rail. They then move downwards together, completing the diaphragm folding and assembly with the concentrate mesh. This achieves the concentrate mesh being sandwiched within the folded diaphragm, i.e., the diaphragm wraps around the concentrate mesh. Specifically, the concentrate mesh is half the size of the diaphragm, positioned directly above it. After cutting, the mesh is fed downwards and folded by the concentrate mesh feeding and folding mechanism 208, which specifically uses the grippers of the flipping cylinder to pick up the concentrate mesh. The cylinder rotates 90 degrees, causing the concentrate mesh to move downwards. Then, through a downward linear conveying mechanism, the concentrate mesh is delivered to the bottom, changing from a horizontal position to an upright position. The diaphragm is now laid flat below, with the bottom edge of the concentrate mesh aligned with the center of the diaphragm. Finally, the concentrate mesh continues to move downwards through the downward folding mechanism 208. At this point, the concentrate mesh and the diaphragm move downwards together along a gap, and the downward movement of the diaphragm achieves the folding function, also clamping the mesh in the middle of the diaphragm.

[0133] The concentrated water mesh feeding and folding mechanism 208 first connects the flipping cylinder gripper with the horizontal traction gripper of the concentrated water mesh picking and conveying mechanism 206. After clamping the concentrated water mesh that has been horizontally conveyed to the position, it flips and conveys it vertically downward, so that the concentrated water mesh can be accurately conveyed to the middle seam of the diaphragm and connects with the diaphragm welding folding and heating mechanism 209.

[0134] The diaphragm welding folding heating mechanism 209 is responsible for welding the folded diaphragm components together using an ultrasonic welding gun. Because the diaphragm is relatively thick, the creases after folding are not very obvious. Therefore, during welding, the diaphragm welding folding heating mechanism 209 heats and heats the creases in the folding seam to solidify the creases. The concentrate mesh is sandwiched in the middle of the diaphragm. The diaphragm welding folding heating mechanism 209 welds the two sides of the diaphragm width, that is, ultrasonically welds the diaphragm and the concentrate mesh on both sides to form weld points, making the two a strong and stable membrane mesh component.

[0135] The second diaphragm module unloading mechanism 210 is responsible for grabbing the prepared diaphragm stacked welding assembly and sending it to the unloading station, which facilitates the grabbing of the diaphragm stacked welding assembly mixing and conveying unit 3. The second diaphragm module unloading mechanism 210 includes a lifting servo module and a rotary cylinder, which are respectively connected to the grippers of the concentrate mesh feeding and folding mechanism 208 to grab the welded diaphragm stacked welding assembly and move it up and down and flip it.

[0136] The diaphragm assembly unloading mechanism 210 uses a synchronous belt pulley transmission system to perform linear traction along the guide rails on both sides, thereby realizing the traction and transportation of the diaphragm stacked assembly gripped by the grippers to the unloading and turnover station.

[0137] like Figure 4As shown, the diaphragm stacking assembly mixing and conveying unit 3 specifically includes a guide rail screw drive mechanism 301, a material handling frame 302, and a gripping clamp 303;

[0138] The guide rail screw drive mechanism 301 consists of two sets of guide rails and a set of motor screw drive components, which drive the diaphragm welding assembly mixing and conveying unit 3 to move back and forth linearly between the diaphragm welding assembly preparation unit 1 and the diaphragm welding assembly preparation unit 2.

[0139] The material handling frame 302 is composed of a square steel tube assembly frame and a cylinder slide rail assembly, which is used to drive the gripping gripper 303 to move up and down and back and forth. The up and down movement of the gripping gripper 303 is used to connect and grip the diaphragm stacked welding assemblies of different heights on the turnover station. The back and forth movement of the gripping gripper 303 is the movement to send the gripped diaphragm stacked welding assembly to the film winding station near the film element mixing and forming unit 6, so that the gripper of the film winding station can grip the film.

[0140] The gripper 303 is composed of a gripper opening and closing cylinder assembly, and is used to grip the prepared diaphragm stacked assembly one and diaphragm stacked assembly two.

[0141] like Figure 5 As shown, the pure water mesh cutting and welding unit 4 specifically includes a pure water mesh unwinding and storage mechanism 401, a pure water mesh material picking and conveying mechanism 402, a pure water mesh cutting mechanism 403, a pure water mesh welding mechanism 404, and a pure water mesh and central tube welding mechanism 405.

[0142] The pure water mesh unwinding and storage mechanism 401 actively unwinds the pure water mesh material mounted on the air shaft by rotating it with a motor; the storage is achieved by the pure water mesh hanging down under the motor and triggering the storage induction switch, so that the tension of the pure water mesh is very small.

[0143] The pure water mesh material conveying mechanism 402 is controlled by a synchronous belt pulley transmission system and a lifting servo module to perform a horizontal linear traction machine, moving up and down to achieve the specified traction action of the gripper clamping the pure water mesh and delivering it to the designated cutting position, welding position and welding pipe position;

[0144] The pure water mesh cutting mechanism 403 is responsible for cutting the pure water mesh; the pure water mesh is pressed by the pure water mesh pressing component, that is, the lifting cylinder, the translation cylinder and the motor in the cutting mechanism drive the cutter to rotate at high speed to cut the pure water mesh.

[0145] The pure water mesh welding mechanism 404 consists of an ultrasonic welding component and a pure water mesh pressure plate component. After the pure water mesh pressure plate component presses the pure water mesh, the welding pressing cylinder of the ultrasonic welding component moves downward to perform ultrasonic welding. After the weld point is completed, the welding pressing cylinder is lifted. After the welding is completed, the pure water mesh material picking and conveying mechanism 402 pulls the pure water mesh welding component to the pure water mesh and central tube welding mechanism 405.

[0146] The pure water mesh and central tube welding mechanism 405 welds the pure water mesh welding assembly to the central tube to form the pure water mesh and central tube welding assembly.

[0147] like Figure 6 As shown, the central tube feeding unit 5 specifically includes a pin clamping assembly 501, a pushing assembly 502, a hole positioning assembly 503, and a central tube storage bin 504; the central tube feeding unit 5 is used to pick up the central tube and position it in a certain accurate location for easy gripping by the gripping robot.

[0148] like Figure 7 , Figure 8 As shown, the membrane element mixing and forming unit 6 specifically includes a film winding station 1 601, a film winding station 2 602, a flattening and gripping robot 603, and a glue-applying robot 604; the film winding station 2 602 has the same structure as the film winding station 1 601.

[0149] The film winding station 601 includes a film winding pin assembly 6011, a mesh spreading platform 6012, an adhesive coating platform 6013, a pure water mesh tensioning assembly 6014, a diaphragm traction assembly 6015, and an adhesive tape wrapping assembly 6016.

[0150] The flattening and gripping robot 603 grips the welded pure water mesh and the central tube welding assembly and places them into the film rolling station. First, the pure water mesh is laid out on the mesh laying platform 6012, and the central tube is placed on the film rolling pin assembly 6011. The two ends of the central tube are fixed and clamped by the film rolling pin assembly 6011. The flattening and gripping robot 603 grips the top first pure water mesh and flips it onto the glue coating platform 6013. The pure water mesh tensioning assembly 6014 on the glue coating platform clamps the first pure water mesh, applies a certain tension, and tightens it.

[0151] The diaphragm traction assembly 6015 docks with the diaphragm stacking assembly mixing and conveying unit 3, gripping the diaphragm stacking assembly for diaphragm insertion. This involves placing the diaphragm stacking assembly on top of the first pure water mesh and conveying it to the root of the central tube. After the diaphragm is in place, the grippers of the traction assembly 6015 release the diaphragm stacking assembly, retracting to its original position and docking with the diaphragm stacking assembly mixing and conveying unit 3 again. The glue-applying robot 604 then applies glue, applying it to the newly inserted diaphragm stacking assembly on the glue-applying platform 6013. Glue is applied along the perimeter of the diaphragm stacking assembly, except for the edge inserted at the root of the central tube, where a continuous, sealed glue layer is applied to the other three edges. This ensures the diaphragm stacking assembly and the second pure water mesh, which is about to be flipped over, are properly aligned. The edges are glued together, and then the flattening and gripping robot 603 continues to grip the second pure water mesh on the mesh laying platform 6012 and flips it to the gluing platform 6013, so that the three edges of the second pure water mesh are glued to the diaphragm stacking assembly. This cycle is repeated. After all the pure water mesh and diaphragm stacking assembly are glued, the membrane is rolled. During the membrane rolling process, the pure water mesh tensioning assembly 6014 on the gluing platform 6013 continuously clamps the first pure water mesh and maintains a certain tension, which is less than the force of the membrane rolling. Finally, it moves forward with the membrane rolling and gradually approaches the central tube. After the membrane rolling is completed, the tape wrapping assembly 6016 automatically applies, wraps, and cuts the tape. Finally, the flattening and gripping robot 603 transports and grips the prepared membrane element product off the production line.

[0152] The 603 flat gripping robot is a six-degree-of-freedom robot, mainly responsible for gripping the central tube for feeding, gripping the pure water mesh and the welding assembly of the central tube for feeding, flipping and flattening the pure water mesh at the film winding station, and gripping and unloading the membrane element after the film winding is completed to the membrane element unloading trolley.

[0153] The 604 glue-applying robot is a six-degree-of-freedom robot, mainly responsible for applying glue between the membrane layers. A square membrane is coated with a fixed amount of glue with three closed sides, and after drying, it forms a "bag". The opening of the bag is aligned with the central tube. Pure water filtered through the bag flows into the central tube through multiple rows of small holes.

[0154] like Figure 9 As shown, the membrane element unloading unit 7 specifically includes a membrane element tilting storage rack 701 and a membrane element unloading trolley 702. The prepared membrane elements are rolled out of the membrane element unloading trolley 702 through the membrane element tilting storage rack 701, making it convenient for personnel to inspect and transport them in a safe area outside the fence.

[0155] A method of using a fully automated industrial membrane element fabrication system, comprising:

[0156] Step 1: Fabrication of the diaphragm stacked assembly;

[0157] Step 2: Mixing and conveying of diaphragm stacked assembly;

[0158] Step 3: Cutting and welding the pure water mesh;

[0159] Step 4: Feeding the central tube and welding the mesh to the central tube;

[0160] Step 5: Membrane element mixing and winding;

[0161] Step 6: Unloading the film winding components.

[0162] In step one, diaphragm lap welding assembly fabrication unit 1 and diaphragm lap welding assembly fabrication unit 2 are respectively used to fabricate different diaphragm lap welding assemblies 1 and 2; wherein,

[0163] The specific usage method of the diaphragm shingle assembly preparation unit 1 includes:

[0164] S11, after manually feeding the concentrate mesh into the concentrate mesh feeding and storage mechanism 101 and feeding the diaphragm material into the diaphragm feeding and storage mechanism 105, press the start button. The mesh material picking and conveying mechanism 102 will then pull out the concentrate mesh and cut it by the mesh cutting mechanism 103. The linear module robot arm 104 will then grab it and send it to the stacking worktable 106.

[0165] S12, while the button is pressed, the grippers of the diaphragm material picking and folding mechanism 107 pull the diaphragm material one onto the stacking worktable 106, realizing half of the concentrate mesh and diaphragm material one being stacked, with the concentrate mesh on top of the diaphragm material one; the grippers of the diaphragm material picking and folding mechanism 107 release and grab the concentrate mesh and diaphragm material a second time, and send the diaphragm to the cutting position through the linear module of the diaphragm material picking and folding mechanism 107, where the diaphragm material one is cut by the diaphragm cutting mechanism 108;

[0166] S13, after cutting, the diaphragm material one is folded by the flipping cylinder and linear module of the diaphragm material picking and folding mechanism 107, and the concentrate mesh is sandwiched in the middle of the diaphragm material one and sent to the welding position. The ultrasonic welding mechanism 109 realizes the three-layer welding of the diaphragm and the concentrate mesh. The diaphragm material picking and folding mechanism 107 sends the welded diaphragm stacked assembly one to the transfer station. The diaphragm assembly unloading mechanism 110 is responsible for grabbing the prepared diaphragm stacked assembly one at the transfer station and sending it to the unloading station, which is convenient for the diaphragm stacked assembly mixing and conveying unit 3 to grab.

[0167] The specific usage method of the diaphragm stacked assembly preparation unit 2 includes:

[0168] S21, after manually feeding the concentrate mesh fabric into the concentrate mesh fabric feeding and storage mechanism 205 and the diaphragm material into the diaphragm material feeding and storage mechanism 201, the start button is pressed. The mesh fabric picking and conveying mechanism 206 then pulls out the concentrate mesh fabric, which is cut by the mesh fabric cutting mechanism 207 and then picked up by the mesh fabric picking and conveying mechanism 206 and sent to the docking position with the mesh fabric unloading and folding mechanism 208. The flipping cylinder gripper of the mesh fabric unloading and folding mechanism 208 picks up the concentrate mesh fabric at the docking position and conveys it downward to the folding position of the diaphragm through the 90-degree flipping cylinder and guide rail of the mesh fabric unloading and folding mechanism 208, that is, to the center of the flat diaphragm.

[0169] S22, while the button is pressed, the grippers of the diaphragm material feeding and conveying mechanism 202 pull out the diaphragm material 2 and cut it by the diaphragm cutting mechanism 203;

[0170] S23, after cutting, the diaphragm material conveying mechanism 202 sends it to the end sealing position, and the diaphragm end sealing mechanism 204 performs thermoplastic sealing on both sides of the diaphragm cut, so that the diaphragm substrate and the coating film layer on the diaphragm are thermally bonded together.

[0171] S24, the end-sealed diaphragm is sent to the folding position by the diaphragm feeding and conveying mechanism 202. At the folding position, the concentrated water mesh fabric is fed from top to bottom by the mesh fabric feeding and folding mechanism 208. The mesh fabric feeding and folding mechanism 208 moves the two together along a gap and downwards for a certain distance to complete the diaphragm center folding and assembly with the concentrated water mesh fabric. The assembly effect is that the concentrated water mesh fabric is sandwiched in the folded diaphragm, that is, the diaphragm wraps the concentrated water mesh fabric; and it is connected to the diaphragm welding folding heating mechanism 209.

[0172] S25, the diaphragm welding folding heating mechanism 209 is responsible for welding the three layers of the folded and assembled diaphragm assembly together by ultrasonic welding gun. Because the second diaphragm material is relatively thick, the creases after folding are not very obvious. Therefore, during welding, the diaphragm welding folding heating mechanism 209 heats and irons the creases in the folding seam to solidify the creases.

[0173] S26, after the diaphragm assembly is welded, the lifting servo module of the diaphragm assembly unloading mechanism 210 sends the gripper of the rotary cylinder upward to grab the diaphragm welded assembly. After grabbing, the rotary cylinder descends and rotates 90 degrees, and is pulled linearly along the guide rails on both sides through the synchronous belt pulley transmission system. This realizes the traction and transportation of the diaphragm welded assembly grabbed by the gripper to the unloading and turnover station, which facilitates the grabbing of the diaphragm welded assembly mixed-handling conveyor unit 3.

[0174] Step two, mixing and conveying of diaphragm stacked assembly; specific usage methods include:

[0175] The guide rail screw drive mechanism 301 drives the material handling frame 302 and the gripping clamp 303 to move back and forth linearly between the diaphragm stacked assembly preparation unit 1 and the diaphragm stacked assembly preparation unit 2; it is used to mix and transport the diaphragm stacked assemblies prepared by the diaphragm stacked assembly preparation unit 1 and the diaphragm stacked assembly preparation unit 2.

[0176] Step 3: Cutting and welding the pure water mesh; specific usage methods include:

[0177] After the pure water mesh is manually fed into the mesh unwinding and storage mechanism 401, the start button is pressed. The mesh material picking and conveying mechanism 402 then pulls out the concentrated water mesh, which is cut by the mesh cutting mechanism 403. The mesh material picking and conveying mechanism 402 then sends the concentrated water mesh to the welding position, where the pure water mesh welding mechanism 404 welds the pure water mesh together. After the pure water mesh is welded according to a certain quantity and requirements, the mesh material picking and conveying mechanism 402 sends the welded pure water mesh to the area below the pure water mesh and central tube welding mechanism 405, waiting to be welded to the central tube.

[0178] Step four: feeding the central tube and welding the mesh to the central tube; specific usage methods include:

[0179] After the pure water mesh is manually fed into the pure water mesh unwinding and storage mechanism 401, the start button is pressed. The pure water mesh material picking and conveying mechanism 402 then pulls the pure water mesh out for cutting by the pure water mesh cutting mechanism 403, and then pulls it out again to the pure water mesh welding mechanism 404, where the grippers are released and the pure water mesh is placed. The pure water mesh material picking and conveying mechanism 402 then returns to the fabric pulling position, pulls the pure water mesh out again for cutting by the pure water mesh cutting mechanism 403, and places the pure water mesh on the first layer of pure water mesh. At this time, the pure water mesh material picking and conveying mechanism 402 returns to the fabric pulling position. The pure water mesh welding mechanism 404 starts welding, and the work is repeated in this cycle. The pure water mesh will be welded together in a progressive order. Repeat the required number of pure water mesh pages. After all the pure water mesh is welded, the pure water mesh material picking and conveying mechanism 402 will pull the pure water mesh assembly to the pure water mesh and central tube welding mechanism 405. At this time, the flattening and gripping robot 603 has already grabbed the central tube and fed it to the pure water mesh and central tube welding mechanism 405 to perform the welding of the bottom layer of pure water mesh and central tube. After the welding is completed, the flattening and gripping robot 603 grabs the tube assembly to the membrane element mixing and winding forming unit 6.

[0180] Step 5: Membrane element mixing and winding; specific usage methods include:

[0181] The flattening and gripping robot 603 grips the welded pure water mesh and the central tube welding assembly and places them into the film rolling station. First, the pure water mesh is laid out on the mesh laying platform 6012, and the central tube is placed on the film rolling pin assembly 6011. The two ends of the central tube are fixed and clamped by the film rolling pin assembly 6011. The flattening and gripping robot 603 grips the top first pure water mesh and flips it onto the glue coating platform 6013. The pure water mesh tensioning assembly 6014 on the glue coating platform clamps the first pure water mesh, applies a certain tension, and tightens it.

[0182] The diaphragm traction assembly 6015 on the membrane winding station docks with the diaphragm overlapping assembly mixing and conveying unit 3, gripping the diaphragm overlapping assembly for diaphragm insertion. This involves placing the diaphragm overlapping assembly on top of the first pure water mesh and delivering it to the root of the central tube. After the diaphragm is in place, the grippers of the membrane traction assembly 6015 release the diaphragm overlapping assembly, retracting to its original position, and docking with the diaphragm overlapping assembly mixing and conveying unit 3 again. The glue-applying robot 604 then begins applying glue, applying it to the newly inserted diaphragm overlapping assembly on the glue-applying platform 6013. Glue is applied along the perimeter of the diaphragm overlapping assembly, except for the edge inserted at the root of the central tube, where glue is applied continuously and tightly to the other three edges. This ensures the diaphragm overlapping assembly connects with the second pure water mesh that is about to be flipped over. The three sides are glued together, and then the flattening and gripping robot 603 continues to grip the second pure water mesh on the mesh laying platform 6012 and flips it to the gluing platform 6013, so that the three sides of the second pure water mesh are glued to the membrane stacking assembly. This process is repeated. After all the pure water mesh and the membrane stacking assembly are glued, the membrane is rolled. During the membrane rolling process, the pure water mesh tensioning assembly 6014 on the gluing platform 6013 continuously clamps the first pure water mesh and maintains a certain tension, which is less than the force of the membrane rolling. Finally, it moves forward with the membrane rolling and gradually approaches the central tube. After the membrane rolling is completed, the tape wrapping assembly 6016 automatically applies, wraps, and cuts the tape. Finally, the flattening and gripping robot 603 transports and grips the prepared membrane element product off the production line.

The diaphragm cutting mechanism (108) is responsible for cutting the diaphragm. It drives the blade to cut the stacked concentrated water mesh and diaphragm on the cutting board through the synchronous belt drive system. The ultrasonic welding mechanism (109) is responsible for welding the concentrated water mesh and the diaphragm folded prefabricated components together at the welding station. Specifically, at this time, since only the diaphragm is folded and the mesh is not folded in the aforementioned stage, the mesh is sandwiched in the middle of the diaphragm, forming a three-layer structure. Welding is to weld these three layers together. The diaphragm assembly unloading mechanism (110) is responsible for grabbing the prepared diaphragm stacked assembly at the transfer station and sending it to the unloading station, so that the diaphragm stacked assembly mixing and conveying unit (3) can grab it.

3. The fully automated industrial membrane element preparation system according to claim 1, characterized in that, The second diaphragm feeding and storage mechanism (201) is mainly used for feeding and storing diaphragm material. The feeding mechanism has a correction function; the storage mechanism is for feeding material outward to ensure that the tension value does not exceed the set value. The diaphragm material feeding and conveying mechanism (202) is responsible for unfolding the diaphragm and pulling it out a certain distance, and cooperating with the diaphragm cutting mechanism (203) to cut it to a fixed length; the cut diaphragm material is sent to the end sealing position and cooperated with the diaphragm end sealing mechanism (204) to achieve end sealing, and finally sent to the diaphragm folding position and cooperated with the concentrate mesh feeding and folding mechanism (208) to achieve folding of the diaphragm material and sandwich the concentrate mesh in the middle; The second diaphragm cutting mechanism (203) is responsible for cutting the diaphragm; The diaphragm end sealing mechanism (204) heat-seales both sides of the diaphragm after the diaphragm is cut, so that the diaphragm substrate and the coating film layer on the diaphragm are heat-fused together. The second (205) feeding and storage mechanism for concentrated water mesh is mainly used for feeding and storing concentrated water mesh. The feeding mechanism has a correction function; the storage mechanism is used to ensure stable feeding under low tension. The second (206) concentrated water mesh material conveying mechanism is responsible for unfolding the concentrated water mesh and pulling it out a certain distance, cooperating with the second (207) concentrated water mesh cutting mechanism to achieve fixed-length cutting; and sending it to the transfer station; The second (207) concentrated water mesh cutting mechanism is responsible for cutting the concentrated water mesh; The concentrate mesh feeding and folding mechanism (208) grabs the cut concentrate mesh and conveys it downwards to the center of the flat diaphragm via a flipping cylinder and guide rail. Then, they move downwards together to complete the diaphragm centering and folding and assembly with the concentrate mesh, so that the concentrate mesh is sandwiched in the folded diaphragm, that is, the diaphragm wraps the concentrate mesh. The specific process is as follows: the size of the concentrate mesh is 1 / 2 of the diaphragm, and the mesh is positioned directly above the diaphragm. After the mesh is cut, it is fed downwards and folded by the concentrate mesh feeding and folding mechanism (208). Specifically, the concentrate mesh is grabbed by the gripper of the flipping cylinder. The mesh is rotated 90 degrees by the cylinder, causing the concentrated water mesh to move downwards. Then, the concentrated water mesh is sent to the bottom through the downward linear conveying mechanism. At this time, the concentrated water mesh changes from a horizontal position to an upright position. The diaphragm is laid flat at the bottom, and the lower edge of the concentrated water mesh is aligned with the middle of the diaphragm. Finally, the concentrated water mesh continues to move downwards through the downward feeding and folding mechanism (208). At this time, the concentrated water mesh and the diaphragm move downwards together along a gap. The downward movement of the diaphragm realizes the folding function and also realizes the clamping of the mesh in the middle of the diaphragm. The concentrated water mesh feeding and folding mechanism (208) first connects with the horizontal traction gripper of the concentrated water mesh picking and conveying mechanism (206) by the flipping cylinder gripper, clamps the concentrated water mesh that has been horizontally conveyed to the position, flips it and conveys it vertically downward, so that the concentrated water mesh can be accurately conveyed to the middle seam of the diaphragm and connects with the diaphragm welding folding heating mechanism (209). The diaphragm welding folding heating mechanism (209) is responsible for welding the folded diaphragm assembly together using an ultrasonic welding gun. Because the diaphragm is relatively thick, the creases after folding are not very obvious. Therefore, during welding, the diaphragm welding folding heating mechanism (209) heats and heats the creases in the folding seam to solidify the creases. The concentrate mesh is sandwiched in the middle of the diaphragm. The diaphragm welding folding heating mechanism (209) welds the two sides of the diaphragm width, that is, the diaphragm and the concentrate mesh are ultrasonically welded on both sides to form weld points, so that the two become a strong and stable membrane mesh assembly.

The gripper (303) consists of a gripper opening and closing cylinder assembly and is used to grip the prepared diaphragm stacked assembly one and diaphragm stacked assembly two.

After the pure water mesh pressure plate assembly presses the pure water mesh, the welding pressing cylinder of the ultrasonic welding assembly moves downward to perform ultrasonic welding. After the weld point is completed, the welding pressing cylinder is lifted. After the welding is completed, the pure water mesh material picking and conveying mechanism (402) pulls the pure water mesh welding assembly to the pure water mesh and central tube welding mechanism (405).

First, the pure water mesh is laid out on the mesh laying platform (6012), and the central tube is placed on the film rolling pin assembly (6011). The two ends of the central tube are fixed and clamped by the film rolling pin assembly (6011). The flattening and gripping robot (603) grips the top first pure water mesh and flips it onto the glue coating platform (6013). The pure water mesh tensioning assembly (6014) on the glue coating platform clamps the first pure water mesh, applies a certain tension, and tightens it. The diaphragm traction assembly (6015) docks with the diaphragm stacking assembly mixing and conveying unit (3), clamps the diaphragm stacking assembly for diaphragm insertion, that is, the diaphragm stacking assembly is placed on top of the first pure water mesh and sent to the root of the central tube. After the diaphragm is inserted, the gripper of the membrane traction assembly (6015) releases the diaphragm stacking assembly, returns to its original position, and docks with the diaphragm stacking assembly mixing and conveying unit (3) again. The glue application robot (604) glue application unit starts to apply glue, that is, glue is applied on the diaphragm stacking assembly that has just been inserted on the glue application platform (6013), and glue is applied along the periphery of the diaphragm stacking assembly. The side inserted at the root of the central tube is not glued, and the other three sides are coated with a sealed and continuous glue, so that the diaphragm stacking assembly and the second pure water mesh that is about to be flipped are connected. The membranes are glued together, and then the flattening and gripping robot (603) continues to grip the second pure water mesh on the mesh spreading platform (6012) and flip it to the gluing platform (6013) to achieve the bonding of the three sides of the second pure water mesh with the membrane stacking assembly. This process is repeated. After all the pure water meshes and the membrane stacking assembly are bonded, the membrane is rolled. During the rolling process, the pure water mesh tensioning assembly (6014) on the gluing platform (6013) continuously clamps the first pure water mesh and maintains a certain tension, which is less than the force of the membrane rolling. Finally, the membrane moves forward and gradually approaches the central tube as the membrane is rolled. After the membrane is rolled, the tape wrapping assembly (6016) automatically applies, wraps, and cuts the tape. Finally, the flattening and gripping robot (603) transports and grips the prepared membrane element product off the production line. The flat gripping robot (603) is a six-degree-of-freedom robot, mainly responsible for gripping the central tube for feeding, gripping the pure water mesh and the welding assembly of the central tube for feeding, flipping and flattening the pure water mesh at the film winding station, and gripping and unloading the membrane element after the film winding is completed to the membrane element unloading trolley.

The method of using the fully automated industrial membrane element preparation system according to claim 9, characterized in that, In step one, diaphragm lap welding assembly preparation unit one (1) and diaphragm lap welding assembly preparation unit two (2) are used to prepare different diaphragm lap welding assemblies one and two, respectively; wherein, The specific usage method of the diaphragm shingled assembly preparation unit 1 (1) includes: S11, the concentrated water mesh is manually fed into the concentrated water mesh feeding and storage mechanism (101), and the diaphragm material is fed into the diaphragm feeding and storage mechanism (105). Then, the start button is pressed, and the mesh picking and conveying mechanism (102) pulls out the concentrated water mesh, which is then cut by the mesh cutting mechanism (103) and then picked up by the linear module robot (104) and sent to the stacking worktable (106). S12, while the button is pressed, the gripper of the diaphragm material picking and folding mechanism (107) pulls the diaphragm material one onto the stacking worktable (106), realizing half stacking of the concentrate mesh and the diaphragm material one, with the concentrate mesh on top of the diaphragm material one; the gripper of the diaphragm material picking and folding mechanism (107) releases and picks up the concentrate mesh and the diaphragm material again, and sends the diaphragm to the cutting position through the linear module of the diaphragm material picking and folding mechanism (107), and the diaphragm material one is cut by the diaphragm cutting mechanism (108); S13, after cutting, the diaphragm material one is folded by the flipping cylinder and linear module of the diaphragm material taking and folding mechanism (107), and the concentrate mesh is sandwiched in the middle of the diaphragm material one and sent to the welding position. The ultrasonic welding mechanism (109) realizes the three-layer welding of the diaphragm and the concentrate mesh. The diaphragm material taking and folding mechanism (107) sends the welded diaphragm stacked assembly one to the transfer station. The diaphragm assembly unloading mechanism one (110) is responsible for grabbing the prepared diaphragm stacked assembly one at the transfer station and sending it to the unloading station, which is convenient for the diaphragm stacked assembly mixing and conveying unit (3) to grab it. The specific usage of the second (2) diaphragm stacked assembly preparation unit includes: S21, the concentrated water mesh is manually fed into the concentrated water mesh unloading and storage mechanism 2 (205), and the diaphragm material 2 is fed into the diaphragm unwinding and storage mechanism 2 (201). After pressing the start button, the mesh material picking and conveying mechanism 2 (206) pulls out the concentrated water mesh and cuts it by the mesh cutting mechanism 2 (207). Then, the mesh material picking and conveying mechanism 2 (206) grabs it and sends it to the docking position with the concentrated water mesh lowering and folding mechanism (208). The flipping cylinder gripper of the concentrated water mesh lowering and folding mechanism (208) grabs the concentrated water mesh at the docking position and conveys it downward to the folding position of the diaphragm through the 90-degree flipping cylinder and guide rail of the concentrated water mesh lowering and folding mechanism (208), that is, to the center of the flat diaphragm. S22, while the button is pressed, the grippers of the diaphragm material feeding and conveying mechanism (202) pull out the diaphragm material two and cut it by the diaphragm cutting mechanism two (203); S23, after cutting, the diaphragm material feeding and conveying mechanism (202) sends it to the end sealing position, and the diaphragm end sealing mechanism (204) performs thermoplastic sealing on both sides of the diaphragm cut, so that the diaphragm substrate and the coating film layer on the diaphragm are thermally bonded together; S24, the end-sealed diaphragm is sent to the folding position by the diaphragm feeding and conveying mechanism (202). At the folding position, the concentrated water mesh is fed from top to bottom by the concentrated water mesh feeding and folding mechanism (208). The concentrated water mesh feeding and folding mechanism (208) moves the two together along a gap for a certain distance to complete the diaphragm center folding and assembly with the concentrated water mesh. The assembly effect is that the concentrated water mesh is sandwiched in the folded diaphragm, that is, the diaphragm wraps the concentrated water mesh. And it is connected to the diaphragm welding folding heating mechanism (209). S25, the diaphragm welding folding heating mechanism (209) is responsible for welding the three layers of the folded diaphragm assembly together by ultrasonic welding gun. Since the second diaphragm material is relatively thick, the creases are not very obvious after folding. Therefore, during welding, the diaphragm welding folding heating mechanism (209) heats and heats the creases in the folding seam to solidify the creases. S26, after the diaphragm assembly is welded, the lifting servo module of the second diaphragm assembly unloading mechanism (210) sends the gripper of the rotary cylinder upward to grab the diaphragm welding assembly. After grabbing, the rotary cylinder descends and rotates 90 degrees. Through the synchronous belt pulley transmission system, it is pulled linearly along the guide rails on both sides, thereby realizing the traction and transportation of the diaphragm stacked welding assembly grabbed by the gripper to the unloading and turnover station, which is convenient for the diaphragm stacked welding assembly mixing and conveying unit (3) to grab. Step two, mixing and conveying of diaphragm stacked assembly; specific usage methods include: The guide rail screw drive mechanism (301) drives the material handling frame (302) and the gripping clamp (303) to move back and forth linearly between the diaphragm superimposed welding assembly preparation unit one (1) and the diaphragm superimposed welding assembly preparation unit two (2); it is used to mix and transport the diaphragm superimposed welding assemblies prepared by the diaphragm superimposed welding assembly preparation unit one (1) and the diaphragm superimposed welding assembly preparation unit two (2); Step 3: Cutting and welding the pure water mesh; specific usage methods include: After the pure water mesh is manually fed into the mesh unwinding and storage mechanism (401), the start button is pressed. The mesh material picking and conveying mechanism (402) then pulls out the concentrated water mesh and cuts it by the mesh cutting mechanism (403). The mesh material picking and conveying mechanism (402) then sends the concentrated water mesh to the welding position, where the pure water mesh welding mechanism (404) welds the pure water mesh together. After the pure water mesh is welded according to a certain quantity and requirements, the mesh material picking and conveying mechanism (402) sends the welded pure water mesh to the area below the pure water mesh and central tube welding mechanism (405) to wait for welding with the central tube. Step four: feeding the central tube and welding the mesh to the central tube; specific usage methods include: After the pure water mesh is manually fed into the pure water mesh unwinding and storage mechanism (401), the start button is pressed. The pure water mesh material picking and conveying mechanism (402) then pulls the pure water mesh out for cutting by the pure water mesh cutting mechanism (403), and then pulls it out again to the pure water mesh welding mechanism (404) and releases the grippers to place the pure water mesh. The pure water mesh material picking and conveying mechanism (402) then returns to the fabric pulling position, pulls the pure water mesh out again for cutting by the pure water mesh cutting mechanism (403), and places the pure water mesh on the first layer of pure water mesh. At this time, the pure water mesh material picking and conveying mechanism (402) returns to the fabric pulling position. At the location, the pure water mesh welding mechanism (404) starts welding, and works in this cycle. The pure water mesh will be welded together in a progressive order. Repeat the required number of pure water mesh pages. After all the pure water mesh is welded, the pure water mesh material picking and conveying mechanism (402) will pull the pure water mesh assembly to the pure water mesh and central tube welding mechanism (405). At this time, the flattening gripping robot (603) has already grabbed the central tube and fed it to the pure water mesh and central tube welding mechanism (405) to perform the welding of the bottom layer of pure water mesh and central tube. After the welding is completed, the flattening gripping robot (603) grabs the tube assembly to the membrane element mixing and rolling forming unit (6). Step 5: Membrane element mixing and winding; specific usage methods include: The flattening and gripping robot (603) grips the welded pure water mesh and the central tube welding assembly and places them into the film rolling station. First, the pure water mesh is laid out on the mesh laying platform (6012), and the central tube is placed on the film rolling pin assembly (6011). The two ends of the central tube are fixed and clamped by the film rolling pin assembly (6011). The flattening and gripping robot (603) grips the top first pure water mesh and flips it onto the glue coating platform (6013). The pure water mesh tensioning assembly (6014) on the glue coating platform clamps the first pure water mesh, applies a certain tension, and tightens it. The diaphragm traction assembly (6015) on the membrane winding station docks with the diaphragm stacking assembly mixing and conveying unit (3), clamps the diaphragm stacking assembly for diaphragm insertion, that is, the diaphragm stacking assembly is placed on top of the first pure water mesh and sent to the root of the central tube. After the diaphragm is inserted, the gripper of the membrane traction assembly (6015) releases the diaphragm stacking assembly, returns to its original position, and docks with the diaphragm stacking assembly mixing and conveying unit (3) again; the glue application robot (604) glue application unit starts to apply glue, that is, on the glue application platform (6013) the diaphragm stacking assembly that has just been inserted, and applies glue along the periphery of the diaphragm stacking assembly. The side inserted at the root of the central tube is not glued, and the other three sides are coated with a sealed and continuous glue, so as to achieve the three-dimensional connection between the diaphragm stacking assembly and the second pure water mesh that is about to be flipped over. The first pure water mesh is glued together, and then the flattening and gripping robot (603) continues to grip the second pure water mesh on the mesh spreading platform (6012) and flips it to the gluing platform (6013) to achieve the bonding of the second pure water mesh with the three sides of the diaphragm stacking assembly. This process is repeated. After all the pure water mesh and diaphragm stacking assembly are bonded, the membrane is rolled. During the membrane rolling process, the pure water mesh tensioning assembly (6014) on the gluing platform (6013) continuously clamps the first pure water mesh and maintains a certain tension, which is less than the force of the membrane rolling. Finally, it moves forward with the membrane rolling and gradually approaches the central tube. After the membrane rolling is completed, the tape wrapping assembly (6016) automatically applies, wraps, and cuts the tape. Finally, the flattening and gripping robot (603) transports and grips the prepared membrane element product off the production line. Step six, unloading the film winding element; specific usage methods include: The membrane element unloading unit (7) specifically includes a membrane element tilting storage rack (701) and a membrane element unloading trolley (702). The membrane element unloading trolley (702) is placed at the opening of the safety enclosure fence and is used by the flat gripping robot (603) to store the prepared membrane elements. The membrane elements are rolled out of the trolley through the membrane element tilting storage rack (701) so that personnel can easily inspect and transport them in the safe area outside the fence.
