Description

Technical Field

[0001] This invention relates to the field of filter element processing technology, and in particular to a membrane bag assembly workstation for industrial RO membrane filter elements and its processing method. Background Technology

[0002] As is well known, RO membrane filter cartridges, also known as reverse osmosis membrane filter cartridges, are formed by rolling up multiple membrane modules. Each membrane module consists of a folded membrane and a spacer built into the folded membrane. The membrane module can filter impurities such as organic matter, colloids, bacteria, and viruses in the raw water, and it has extremely high filtration efficiency, especially for impurities such as inorganic salts and heavy metals. Therefore, the filtration effect of the purifier is directly related to the filtration effect of the reverse osmosis filter cartridge membrane module. Especially for industrial-grade RO membrane filter cartridges, the membrane module size is larger than that of household RO membrane filter cartridges, making the production and processing of industrial-grade RO membrane filter cartridge membrane modules more difficult. One major challenge is the precise folding of the membrane and the precise positioning and assembly of the spacer within the folded membrane. If manual folding and assembly are used, the processing efficiency is slow and the size of the assembled membrane module is difficult to standardize.

[0003] A Chinese patent with publication number CN113304615B discloses a fully automated production equipment and processing technology for RO membrane filter elements. The RO membrane filter element production equipment includes a frame, a first placement table, and a second placement table. The frame is equipped with a feeding mechanism, a stacking mechanism, and a winding mechanism. The feeding mechanism includes a mesh feeding and cutting device, a membrane feeding and cutting device, a guide cloth feeding and cutting device, and a central tube clamping and rotating device. The stacking mechanism includes a first robotic arm, a second robotic arm, a third robotic arm, and a folding device. The winding mechanism includes a slanted feeding device, a welding device, an outer guide cloth feeding device, and a film pasting device. The frame is also equipped with a translation conveying device. The folding device includes a mounting frame and two pressure claws mounted on the mounting frame. The mounting frame is raised and lowered relative to the frame by a first lifting electric cylinder, and the pressure claws are movably mounted on the mounting frame by a pushing cylinder.

[0004] However, the aforementioned RO membrane filter production equipment has the following drawbacks: During the folding process, the equipment grasps the membrane sheet and lays it flat on the first support platform. Then, it grasps half the length of the membrane sheet and lays the mesh flat on the membrane sheet. A push cylinder pushes the pressure claws towards the first support platform. Then, the first lifting electric cylinder drives the mounting frame to descend, causing the two pressure claws to press against the membrane sheet and the mesh. At the same time, the first mechanical claw moves the end of the membrane sheet without the mesh to the other end until the pressure claws form a crease in the middle of the membrane sheet. The mesh is sandwiched inside the folded membrane sheet to initially form the membrane assembly. Subsequently, the membrane assembly is assembled with the flow guide cloth to form a filter unit. However, there is a problem with the above equipment during the folding process: during the process of the first robotic arm moving the end of the membrane sheet without the mesh to the other end, it cannot be guaranteed that the crease position is in the middle of the membrane sheet with each fold. It may shift to both sides, which makes it impossible to guarantee the production yield of the membrane assembly. This needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide a membrane bag assembly workstation for industrial RO membrane filter elements and its processing method, which has the advantages of high processing accuracy, uniform size, and high processing efficiency.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a membrane bag assembly workstation for industrial RO membrane filter cartridges, comprising a base station body, wherein the base station body is provided with:

[0007] A diaphragm assembly mechanism includes an assembly structure, wherein an assembly slot is provided through the assembly structure.

[0008] The membrane feeding mechanism includes a membrane roll module, a membrane dragging module, and a membrane cutting module for cutting the membrane. The membrane dragging module is used to pull out the membrane from the membrane roll module and lay it on the assembly structure.

[0009] The separator mesh feeding mechanism includes a separator mesh roll module, a separator mesh feeding module, and a separator mesh cutting module for cutting the separator mesh. The separator mesh feeding module includes a separator mesh clamping structure, which can switch between a clamping state and a releasing state relative to the separator mesh. The separator mesh feeding module is used to push the separator mesh to the separator mesh clamping structure for clamping, and drive the separator mesh clamping structure holding the separator mesh to extend into the assembly gap, while pushing the diaphragm to embed into the assembly gap to achieve folding.

[0010] The diaphragm assembly discharging mechanism includes a transverse lifting module and a diaphragm assembly clamping component. The diaphragm assembly clamping component is used to clamp the folded connection of the diaphragm. The transverse lifting module can drive the diaphragm assembly clamping component to move in space relative to the base station body to achieve discharging.

[0011] By adopting the above technical solution, during the assembly stage, the diaphragm dragging module pulls the diaphragm from the diaphragm roll module onto the assembly structure, allowing the diaphragm to cover the assembly gap. Then, the mesh feeding module pushes the mesh from the mesh roll module to the mesh clamping structure for clamping. Next, the mesh feeding module drives the mesh clamping structure, holding the mesh, to align with the assembly gap and move towards the assembly structure. As the mesh feeding module drives the mesh clamping structure into the assembly gap, the mesh clamping structure pushes the middle of the diaphragm into the gap, folding it in half. Simultaneously, the mesh within the mesh clamping structure embeds into the folded diaphragm, assembling it into a diaphragm assembly. The horizontal lifting module drives the diaphragm assembly clamping component to move below the assembly gap, using the diaphragm assembly clamping component to clamp the folded connection of the diaphragm. Then, the horizontal lifting module pulls the assembled diaphragm assembly out of the assembly gap for discharge. During discharge, the horizontal lifting module... The diaphragm assembly clamping assembly pulls the diaphragm assembly away from the assembly gap. When the diaphragm near the diaphragm cutting module is pulled out of the assembly gap to the predetermined cutting position, the diaphragm cutting module cuts the diaphragm. Simultaneously, when the diaphragm assembly unloading mechanism pulls the mesh out of the assembly gap by a predetermined length, the mesh cutting module cuts the mesh, completing the processing of the diaphragm assembly. Afterward, the mesh loading mechanism resets. By repeating the above operation process, continuous processing of the diaphragm assembly is achieved. In addition, the invention utilizes the mesh clamping structure to push vertically downward to achieve folding in the middle of the diaphragm, so that each diaphragm can be folded in the same position. At the same time, the mesh clamping structure accurately embeds the mesh into the folded diaphragm, improving the processing and assembly accuracy between the diaphragm and the mesh, ensuring that the size of each diaphragm assembly is consistent, thereby improving the yield rate. At the same time, the assembly and unloading of the diaphragm assembly are carried out simultaneously, saving processing time and achieving the effects of high processing accuracy, uniform size, and high processing efficiency.

[0012] A further configuration of the present invention is as follows: the assembly structure includes a first support platform and a second support platform arranged opposite to each other, the first support platform and the second support platform are provided with rotating rollers opposite to each other, the assembly gap is formed between the corresponding rotating rollers on the first support platform and the second support platform, and the first support platform and the second support platform are provided with a clamping cylinder opposite to each other, and the piston rod end of the clamping cylinder is provided with a clamping block.

[0013] By adopting the above technical solution, the width of the assembly gap can be adjusted by adjusting the relative positions of the first and second support platforms. When the mesh feeding mechanism pushes the mesh into the assembly gap, embedding the mesh within the folded membrane, the mesh clamping structure holds the mesh as it moves downwards within the assembly gap. The rotating rollers on both sides can roll in cooperation with the sides of the mesh clamping structure, preventing scratches from occurring as the lower end of the mesh clamping structure extends into the assembly gap. This also increases the lowering efficiency of the mesh clamping structure. Smoothness: During the feeding process of the partition net, the partition net is clamped by the partition net clamping structure and inserted into the assembly gap. Then, the partition net clamping structure releases its grip on the partition net. At the same time, the partition net feeding module pushes the partition net to move downward relative to the partition net clamping structure a certain distance, so that the fold connection between the partition net and the membrane is aligned. At this time, the pressing cylinder drives the clamping blocks on both sides to clamp the part of the partition net that extends downward from the partition net clamping structure. This ensures that the partition net will not accidentally rise upward and detach from the assembly gap during the upward process of the partition net clamping structure which is in the released state.

[0014] A further provision of the present invention is that: the assembly structure is provided with a buffer structure on the side facing the diaphragm assembly discharge mechanism, the buffer structure includes a position adjustment module and a roller shaft rotatably disposed on the position adjustment module, and the diaphragm assembly discharge mechanism pulls the diaphragm so that its surface rolls in cooperation with the roller shaft.

[0015] By adopting the above technical solution, the adjustment module is used to adjust the relative position between the roller and the assembly gap to keep it in a suitable position, so that when the film assembly discharge mechanism pulls the film assembly to discharge, the outer surface of the film can roll and cooperate with the roller, preventing the film from being rubbed and scratched by the assembly structure.

[0016] A further feature of the present invention is that the diaphragm assembly clamping assembly includes a plurality of clamping cylinders arranged side by side on the transverse lifting module, and clamping hot plates are provided on the inner walls of the two clamping claws on both sides of the clamping cylinders.

[0017] By adopting the above technical solution, the clamping cylinder drives the clamping hot plate to clamp the crease connection of the membrane assembly. At the same time, during the process of the transverse lifting module pulling the membrane assembly out of the material, the clamping hot plate can be used to perform hot welding on the crease connection of the membrane assembly, so that the membrane at both ends of the crease connection can be welded to the lower end of the mesh to form a whole. This allows the membrane assembly to be hot welded at the same time during the material discharge process, improving the processing efficiency of the membrane assembly.

[0018] A further feature of the present invention is that the mesh lowering module further includes a lifting drive structure for driving the mesh clamping structure to move up and down, the lifting drive structure is provided with a drive roller assembly, and the drive roller assembly drives the mesh in the mesh roll module to be lowered to the mesh clamping structure.

[0019] By adopting the above technical solution, the drive roller assembly can drive the partition net to be fed into the assembly gap, and the drive roller assembly can clamp the partition net. The present invention enables flexible switching between the dual clamping methods of the drive roller assembly and the partition net clamping structure, so that the partition net will not detach from the partition net feeding mechanism during the feeding process.

[0020] A further configuration of the present invention is as follows: the mesh clamping structure includes a fixed clamping plate assembly and a movable clamping plate assembly disposed opposite to the lifting drive structure; the lifting drive structure is provided with a horizontal push cylinder, which drives the movable clamping plate assembly to press against or move away from the fixed clamping plate assembly.

[0021] By adopting the above technical solution, the movable clamping plate assembly can be brought close to the fixed clamping plate assembly by the horizontal push cylinder to achieve clamping of the mesh, and the mesh can be released by retracting the piston rod of the horizontal push cylinder to move the movable clamping assembly away from the fixed clamping plate assembly.

[0022] A further provision of the present invention is that a crease-applying adhesive mechanism is provided between the diaphragm feeding mechanism and the diaphragm assembly mechanism, the crease-applying adhesive mechanism being used to apply adhesive tape to the crease joint of the diaphragm.

[0023] By adopting the above technical solution, the crease-applying adhesive mechanism applies tape to the crease joint of the diaphragm, ensuring that the crease joint of the diaphragm will not break due to excessive downward pressure during the process of the mesh lowering module pressing the diaphragm into the assembly gap.

[0024] A further feature of the present invention is that a visual inspection module is provided between the diaphragm roll module and the crease adhesive applicator, and the visual inspection module is electrically connected to the diaphragm dragging module.

[0025] By adopting the above technical solution, the vision inspection module is used to detect the surface condition of the membrane. When a defective membrane is detected, it can provide feedback to control the membrane dragging module to pause its work, making it convenient to remove the defective membrane.

[0026] A further provision of the present invention is that the base station body is also provided with a defective product rejection mechanism, the defective product rejection mechanism including a visual inspection module, a multi-axis mechanical clamping module and a waste tray, the visual inspection module being electrically connected to the multi-axis mechanical clamping module, the visual inspection module being used to visually inspect defective films and control the multi-axis mechanical clamping module to clamp and transport the defective films to the waste tray.

[0027] By adopting the above technical solution, when the vision inspection module detects a defect on the surface of the diaphragm, the defective diaphragm can be clamped by the multi-axis mechanical clamping module and transported to the waste tray for collection.

[0028] Another technical objective of this invention is to provide an assembly method for an industrial RO membrane filter cartridge assembly workstation, comprising the following steps:

[0029] S1: Diaphragm feeding: The diaphragm dragging module pulls the diaphragm in the diaphragm roll module onto the assembly structure, so that the diaphragm covers the assembly structure and the assembly gaps;

[0030] S2: Mesh feeding: The mesh inside the mesh roll module is pushed to the mesh clamping structure for clamping using the mesh feeding module. Then the mesh feeding module drives the mesh clamping structure holding the mesh to align with the assembly gap and move towards the assembly structure.

[0031] S3: Membrane assembly: During the process of the mesh feeding module driving the mesh clamping structure to extend into the assembly gap, the mesh clamping structure drives the mesh to push the middle of the membrane into the assembly gap to achieve folding. At the same time, the mesh located in the mesh clamping structure is embedded in the folded membrane to complete the assembly.

[0032] S4: Diaphragm assembly unloading: The lateral lifting module drives the diaphragm assembly clamping component to move below the assembly gap. The diaphragm assembly clamping component clamps the folded connection of the diaphragm, and then the lateral lifting module pulls the assembled diaphragm assembly through the diaphragm assembly clamping component to unload the diaphragm assembly.

[0033] S5: Diaphragm cutting: During discharge, the horizontal lifting module drives the diaphragm assembly clamping component to pull the diaphragm assembly away from the assembly gap. When the diaphragm near the diaphragm cutting module is pulled out from the assembly gap to the predetermined cutting position, the diaphragm is cut by the diaphragm cutting module.

[0034] S6: Mesh Cutting: The horizontal lifting module clamps the membrane assembly fold connection through the membrane assembly clamping assembly. The mesh clamping structure releases the mesh, and then the mesh lowering module drives the mesh clamping structure to rise. When the mesh clamping structure rises to a predetermined height relative to the mesh, the mesh cutting module cuts the mesh, and then the mesh feeding mechanism resets.

[0035] S7: Diaphragm assembly unloading: The horizontal lifting module pulls the assembled diaphragm assembly away from the assembly gap through the diaphragm assembly clamping component, thus completing the assembly of the diaphragm assembly;

[0036] S8: Repeat steps S1-S7.

[0037] In summary, the present invention has the following beneficial effects:

[0038] The system employs a membrane feeding mechanism, a mesh feeding mechanism, a membrane assembly mechanism, and a membrane assembly discharge mechanism, all integrated into the base station body. The membrane feeding mechanism lays the membrane onto the assembly structure, covering the assembly gaps. The mesh feeding mechanism then transports the mesh to the membrane assembly mechanism. A mesh clamping structure presses down on the mesh, simultaneously pressing the membrane into the assembly gaps to achieve a fold. The mesh is then positioned between the folded membranes to form a membrane assembly. Finally, the membrane assembly discharge mechanism uses a membrane assembly clamping component to hold the folded joints of the membrane assembly. A horizontal lifting module drives the membrane assembly clamping component to pull the membrane assembly, thus discharging it. This system offers high processing precision, uniform dimensions, and high processing efficiency. Attached Figure Description

[0053] The invention will now be further described with reference to the accompanying drawings.

[0054] An industrial RO membrane filter cartridge membrane bag assembly workstation, such as Figure 1-5 and Figure 13As shown, the system includes a base station body 1. The base station body 1 is equipped with a diaphragm feeding mechanism 3, a mesh feeding mechanism 4, a diaphragm assembly mechanism 2, and a diaphragm assembly discharging mechanism 5. The diaphragm assembly mechanism 2 includes an assembly structure 21, on which an assembly gap 21a is provided. The diaphragm feeding mechanism 3 includes a diaphragm roll module 31, a diaphragm dragging module 32, and a diaphragm cutting module 33 for cutting the diaphragm 40. The diaphragm dragging module 32 is used to pull out the diaphragm 40 from the diaphragm roll module 31 and lay it on the assembly structure 21. The mesh feeding mechanism 4 includes a mesh roll module 41, a mesh feeding module 42, and a mesh cutting module 43 for cutting the mesh 30. The mesh cutting module 43 includes a cutter 431 and a lead screw assembly 432. The cutter 431 cuts the mesh 30 laterally through the lead screw assembly 432. The mesh feeding module 42 includes a mesh clamping structure 421, which can switch between a clamping state and a releasing state relative to the mesh 30. The mesh feeding module 42 is used to push the mesh 30 in the mesh roll module 41 to the mesh clamping structure 421 for clamping, and drive the mesh clamping structure 421 holding the mesh 30 to extend into the assembly gap 21a, while simultaneously pushing the diaphragm 40 into the assembly gap 21a to achieve folding. The mesh roll module 41, the mesh feeding module 42, the diaphragm roll module 31, and the diaphragm are all connected. Each of the dragging modules 32 is provided with an elastic tensioning mechanism 7. The elastic tensioning mechanism 7 always has a tendency to drive the mesh 30 between the corresponding mesh roll module 41 and the mesh feeding module 42, and between the membrane roll module 31 and the membrane dragging module 32, to always maintain a taut state. In this embodiment, a crease adhesive applicator 6 is provided between the membrane feeding mechanism 3 and the membrane assembly mechanism 2. The crease adhesive applicator 6 is used to apply tape to the crease joint of the membrane 40. By applying tape to the crease joint of the membrane 40 using the crease adhesive applicator 6, the crease joint of the membrane 40 will not be affected by excessive downward pressure during the process of the mesh feeding module 42 pressing the membrane down to the assembly gap 21a. The base station body 1 is also equipped with a defective product rejection mechanism 8, which includes a visual inspection module 83, a multi-axis mechanical clamping module 81, and a waste tray 82. The visual inspection module 83 is electrically connected to the diaphragm dragging module 32 and the multi-axis mechanical clamping module 81, respectively. The visual inspection module 83 is used to visually inspect defective diaphragms 40 and control the multi-axis mechanical clamping module 81 to clamp and transport the defective diaphragms to the waste tray 82. When the visual inspection module 83 detects a defect on the surface of the diaphragm 40, it can provide feedback to control the diaphragm dragging module 32 to stop working, and at the same time use the multi-axis mechanical clamping module 81 to clamp and transport the defective diaphragm 40 to the waste tray 82 for collection.

[0055] like Figure 11-12As shown, the assembly structure 21 includes a first support platform 211 and a second support platform 212 arranged opposite to each other. Rotating rollers 213 are arranged opposite to the first support platform 211 and the second support platform 212. An assembly gap 21a is formed between the corresponding rotating rollers 213 on the first support platform 211 and the second support platform 212. A clamping cylinder 214 is arranged opposite to the first support platform 211 and the second support platform 212. A clamping block 215 is correspondingly provided at the piston rod end of the clamping cylinder 214. By adjusting the first support platform 211 and the second support platform 212... The relative position of the mesh can be adjusted to adjust the width of the assembly gap 21a. When the mesh feeding mechanism 4 pushes the mesh 30 into the assembly gap 21a, so that the mesh 30 is embedded in the folded membrane 40 in the assembly gap 21a, the mesh clamping structure 421 clamps the mesh 30 and moves it downward in the assembly gap 21a. The rotating rollers 213 on both sides can roll with the two sides of the mesh clamping structure 421, which can prevent the lower end of the mesh clamping structure 421 from being scratched during the process of extending into the assembly gap 21a. At the same time, it also increases the mesh clamping structure 421 Smoothness of the downward movement process; During the feeding process of the partition net, the partition net 30 is clamped by the partition net clamping structure 421 and inserted into the assembly gap 21a. Then, the partition net clamping structure 421 releases its clamping on the partition net. At the same time, the partition net feeding module 42 pushes the partition net 30 downward relative to the partition net clamping structure 421 by a certain distance, so that the partition net 30 is aligned with the fold connection of the diaphragm 40. At this time, the pressing cylinder 214 drives the clamping blocks 215 on both sides to clamp the part of the partition net 30 that extends downward from the partition net clamping structure 421, so that the partition net 30 is in a state of release. During the upward movement of the mesh clamping structure, the mesh 30 will not bounce upward and detach from the assembly gap 21a under the action of the elastic tensioning mechanism 7. It should be noted that in this embodiment, the length of the first support platform 211 is longer than the length of the second support platform 212. In this way, when the diaphragm assembly discharge mechanism 5 pulls the assembled diaphragm assembly for discharge, the diaphragm assembly can be cut by the diaphragm cutting module 33 on the side close to the diaphragm cutting module 33 during the pulling process, thereby improving the processing efficiency of the diaphragm assembly of the present invention.

[0056] like Figure 8-9 As shown, the assembly structure 21 has a buffer structure on the side facing the diaphragm assembly discharge mechanism 5. The buffer structure includes a position adjustment module 216 and a roller 217 rotatably mounted on the position adjustment module 216. The diaphragm assembly discharge mechanism 5 pulls the diaphragm 40 so that its surface rolls with the roller 217. The adjustment module is used to adjust the relative position between the roller 217 and the assembly gap 21a to keep it in a suitable position, so that during the process of the diaphragm assembly discharge mechanism 5 pulling the diaphragm assembly to discharge, the outer surface of the diaphragm 40 can roll with the roller 217, preventing the diaphragm 40 from being rubbed and scratched by the assembly structure 21.

[0057] like Figure 10As shown, the diaphragm assembly clamping assembly 52 includes several clamping cylinders 521 arranged side by side on the transverse lifting module 51, and clamping hot plates 522 are provided on the inner walls of the two sides of the clamping claws of the clamping cylinders 521. The clamping cylinders 521 drive the clamping hot plates 522 to clamp the fold connection of the diaphragm assembly. At the same time, during the process of the transverse lifting module 51 pulling the diaphragm assembly out of the material, the clamping hot plates 522 can be used to hot weld the fold connection of the diaphragm assembly, so that the diaphragm 40 folded at both ends at the fold connection can be welded to the lower end of the partition 30 to form a whole. This allows the diaphragm assembly to be hot welded at the same time during the material out of the material, which improves the processing efficiency of the diaphragm assembly.

[0058] like Figure 4-7 As shown, the mesh lowering module 42 also includes a lifting drive structure 422 that drives the mesh clamping structure 421 to move up and down. The lifting drive structure 422 is equipped with a drive roller assembly 423. The drive roller assembly 423 is driven by a servo motor 4231 to achieve relative rotation. The relative rotation of the drive roller assembly 423 drives the mesh to be lowered to the mesh clamping structure 421. The drive roller assembly 423 can drive the mesh to be lowered into the assembly gap 21a, and the drive roller assembly 423 can clamp the mesh 30. The present invention, through the flexible switching between the dual clamping methods of the drive roller assembly 423 and the mesh clamping structure 421 for the mesh 30, ensures that the mesh 30 will not detach from the mesh feeding mechanism 4 during the feeding process. The mesh clamping structure 421 includes a relative... The lifting drive structure 422 has a fixed clamping plate assembly 4211 and a movable clamping plate assembly 4212. The lifting drive structure 422 is equipped with a horizontal push cylinder 4213. The horizontal push cylinder 4213 drives the movable clamping plate assembly 4212 to press against or move away from the fixed clamping plate assembly 4211. The horizontal push cylinder 4213 pushes the movable clamping plate assembly 4212 closer to the fixed clamping plate assembly 4211 to achieve clamping of the mesh 30. The horizontal push cylinder 4213 retracts the piston rod to move the movable clamping assembly away from the fixed clamping plate assembly 4211 to achieve release of the mesh 30. In this embodiment, there is a clamping gap between the fixed clamping plate assembly 4211 and the movable clamping plate assembly 4212, and the gap gradually decreases from the end away from the assembly structure 21 to the end closer to the assembly structure 21.

[0059] The basic working principle of this invention is as follows: During the assembly stage, the diaphragm dragging module 32 pulls the diaphragm 40 in the diaphragm roll module 31 onto the assembly structure 21. During the dragging process, the crease adhesive applicator 6 applies adhesive tape to the crease connection point in the middle of the diaphragm 40. Finally, the diaphragm dragging module 32 lays the diaphragm 40 onto the assembly structure 21, so that the crease connection point of the diaphragm 40 is directly aligned with the assembly gap 21a. Then, the drive roller assembly 423 of the mesh feeding module 42 pushes the mesh 30 in the mesh roll module 41 to the mesh clamping structure 421 for clamping, so that the lower end of the mesh 30 is slightly exposed at the lower end of the mesh clamping structure 421. Immediately afterwards, the mesh feeding module 42 drives the mesh clamping structure 421 holding the mesh 30 to align with the assembly gap 21a. As the membrane 30 moves towards the assembly structure 21, the mesh feeding module 42 drives the mesh clamping structure 421 to extend into the assembly gap 21a. During this process, the lower end of the mesh 30 in the mesh clamping structure 421 pushes the tape at the fold joint into the assembly gap 21a, causing the membrane 40 to be folded relative to the adhesive part at the fold joint. The adhesive tape prevents the cut end face of the lower end of the mesh 30 from damaging the surface of the membrane 40. This allows the mesh 30 located in the mesh clamping structure 421 to be embedded inside the folded membrane 40 to assemble into a membrane assembly. Then, the mesh clamping structure 421 releases the mesh, while the drive roller assembly 423 clamps the mesh 30. Subsequently, the mesh feeding module 42 drives the mesh clamping structure 421 to lift relative to the mesh 30. After the structure 421 moves to the predetermined height, the mesh cutting module 43 cuts the mesh 30. Then, the mesh feeding mechanism 4 resets, and the membrane assembly clamping assembly 52 clamps the lower end of the membrane assembly, so that the lower ends of the membrane 40 and the mesh 30 are clamped by the membrane assembly clamping assembly 52. ​​Then, the transverse lifting module 51 of the membrane assembly discharge mechanism 5 pulls the membrane assembly clamping assembly 52 to discharge the membrane assembly. During the discharge process, the clamping hot plate 522 on the membrane assembly clamping assembly 52 can be used to heat weld the crease connection of the membrane assembly, so that the membrane 40 and the mesh 30 are welded into a whole membrane assembly. During the discharge, the transverse lifting module 51 drives the membrane assembly clamping assembly 52 to pull the membrane assembly away from the assembly gap 21a. When it approaches the membrane cutting... When the diaphragm 40 on one side of module 33 is pulled out from the assembly gap 21a to the predetermined cutting position, the diaphragm 40 is cut by the diaphragm cutting module 33. By repeating the above operation process, continuous processing of the diaphragm assembly is achieved. In addition, the present invention provides an elastic tensioning mechanism 7 between the mesh roll module 41 and the mesh feeding module 42, and between the diaphragm roll module 31 and the diaphragm dragging module 32, so that the mesh 30 and the diaphragm at the corresponding positions are always kept taut, improving the accuracy of the cutting length of the diaphragm 40 and the mesh 30. The mesh clamping structure 421 is used to push the diaphragm vertically downward to achieve the folding of the middle part of the diaphragm, so that each diaphragm 40 can be folded in the same position. At the same time, the mesh clamping structure 421 accurately embeds the mesh 30 into the folded diaphragm 40.Improving the precision of the processing and assembly between the diaphragm 40 and the spacer 30 ensures that the dimensions of each diaphragm assembly are consistent, thereby increasing the yield rate. Furthermore, the assembly and unloading of the diaphragm assemblies are carried out simultaneously, saving processing time and resulting in high processing accuracy, uniform dimensions, and high processing efficiency.

[0060] Another technical objective of this invention is to provide an assembly method for an industrial RO membrane filter cartridge assembly workstation, comprising the following steps:

[0061] S1: Diaphragm feeding: The diaphragm dragging module pulls the diaphragm in the diaphragm roll module onto the assembly structure, so that the diaphragm covers the assembly structure and the assembly gaps;

[0062] S2: Mesh feeding: The mesh inside the mesh roll module is pushed to the mesh clamping structure for clamping using the mesh feeding module. Then the mesh feeding module drives the mesh clamping structure holding the mesh to align with the assembly gap and move towards the assembly structure.

[0063] S3: Membrane assembly: During the process of the mesh feeding module driving the mesh clamping structure to extend into the assembly gap, the mesh clamping structure drives the mesh to push the middle of the membrane into the assembly gap to achieve folding. At the same time, the mesh located in the mesh clamping structure is embedded in the folded membrane to complete the assembly.

[0064] S4: Diaphragm assembly unloading: The lateral lifting module drives the diaphragm assembly clamping component to move below the assembly gap. The diaphragm assembly clamping component clamps the folded connection of the diaphragm, and then the lateral lifting module pulls the assembled diaphragm assembly through the diaphragm assembly clamping component to unload the diaphragm assembly.

[0065] S5: Diaphragm cutting: During discharge, the horizontal lifting module drives the diaphragm assembly clamping component to pull the diaphragm assembly away from the assembly gap. When the diaphragm near the diaphragm cutting module is pulled out from the assembly gap to the predetermined cutting position, the diaphragm is cut by the diaphragm cutting module.

[0066] S6: Mesh Cutting: The horizontal lifting module clamps the membrane assembly fold connection through the membrane assembly clamping assembly. The mesh clamping structure releases the mesh, and then the mesh lowering module drives the mesh clamping structure to rise. When the mesh clamping structure rises to a predetermined height relative to the mesh, the mesh cutting module cuts the mesh, and then the mesh feeding mechanism resets.

[0067] S7: Diaphragm assembly unloading: The horizontal lifting module pulls the assembled diaphragm assembly away from the assembly gap through the diaphragm assembly clamping component, thus completing the assembly of the diaphragm assembly;

[0068] S8: Repeat steps S1-S7.

[0069] The above description is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this patent application are included in the scope of this patent application.
