Description

Technical Field

[0001] The invention relates to the technical field of filter element processing, and in particular to a membrane bag assembly workstation for an industrial RO membrane filter element. Background Art

[0002] As we all know, RO membrane filter element, also known as reverse osmosis membrane filter element, is formed by wrapping multiple membrane components. Each membrane component is composed of a folded membrane and a partition net built into the folded membrane. The membrane component can filter organic matter, colloids, bacteria, viruses and other impurities in the raw water, especially for inorganic salts, heavy metal examples and other impurities. It has extremely high filtration efficiency. Therefore, the filtration effect of the purifier is directly related to the filtration effect of the reverse osmosis filter element membrane component. Especially for industrial-grade RO membrane filter elements, the size of its membrane component is larger than that of household RO membrane filter elements, resulting in the production and processing of the membrane component of industrial-grade RO membrane filter elements. One of the major difficulties that needs to be overcome is the folding of the membrane and the precise assembly of the partition net in the folded membrane. If manual folding and assembly are used, the processing efficiency is slow and the size of the assembled membrane component is difficult to unify.

[0003] The existing Chinese patent with announcement number CN113304615B discloses a fully automatic production equipment and processing technology of RO membrane filter element, wherein the RO membrane filter element production equipment includes a frame, a first placement table and a second placement table, the frame is provided with a feeding mechanism, a stacking mechanism, and a rolling mechanism; the feeding mechanism includes a screen 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 manipulator, a second manipulator, a third manipulator and a folding device; the rolling mechanism includes an oblique feeding device, a welding device, an outer layer guide cloth feeding device and a film pasting device, and the frame is also provided with a translation conveying device; the folding device includes a mounting frame and two pressing claws arranged on the mounting frame, the mounting frame is lifted and lowered relative to the frame by a first lifting electric cylinder, and the pressing claws are movably arranged on the mounting frame by a push cylinder.

[0004] However, the above-mentioned RO membrane filter element production equipment has the following disadvantages: when the equipment is folding, it grabs the diaphragm and spreads it flat on the first prevention table, then grabs the partition net of half the length of the diaphragm and spreads it flat on the diaphragm, and pushes the pressure claw to move toward the first prevention table by the push cylinder, and then uses the first lifting electric cylinder to drive the mounting frame to descend, driving the two pressure claws to press on the diaphragm and the partition net, and at the same time, the first mechanical claw drives the end of the diaphragm that is not stacked with the partition net to move to the other end until the pressure claw forms a crease in the middle of the diaphragm, and the partition net is clamped in the folded diaphragm to initially form the above-mentioned diaphragm assembly, and the subsequent diaphragm assembly is assembled with the guide cloth to form a filter unit. However, there is a problem in the folding process of the above-mentioned equipment: that is, in the process of the first mechanical arm driving the end of the diaphragm that is not stacked with the partition net to move to the other end, it cannot be guaranteed that the crease position is in the middle of the diaphragm for each fold, and it may be offset to both sides, so that the production yield of the diaphragm assembly cannot be guaranteed, which needs to be improved urgently. Summary of the invention

[0005] The object of the present invention is to provide a membrane bag assembly workstation for an industrial RO membrane filter element, which has the effects of high processing accuracy, uniform size and high processing efficiency.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A membrane bag assembly workstation for an industrial RO membrane filter element, comprising a base station body, characterized in that the base station body is provided with:

[0007] The diaphragm assembly assembly mechanism comprises an assembly platform, wherein an assembly gap is formed through the assembly platform;

[0008] A diaphragm feeding mechanism, used to feed the diaphragm and spread it on the assembly platform;

[0009] A mesh feeding mechanism; comprising a mesh reel module, a mesh lowering module and a mesh cutting module for cutting the mesh, wherein the mesh lowering module comprises a mesh clamping structure, wherein the mesh clamping structure can switch between a clamping state and a releasing state relative to the mesh, wherein the mesh lowering module is used to push the mesh to the mesh clamping structure for clamping, and to drive the mesh clamping structure clamping the mesh into the assembly gap, and at the same time, to push the membrane to be embedded in the assembly gap to achieve folding;

[0010] The diaphragm assembly discharging mechanism is arranged below the assembling platform and is used for pulling the folded diaphragm embedded with the partition net from the assembling gap for discharging.

[0011] By adopting the above technical scheme, during the assembly stage, the diaphragm is loaded onto the assembly platform by the diaphragm loading mechanism so that the diaphragm is spread on the assembly platform and covers the assembly gap. Then, the partition net in the partition net drum module is pushed to the partition net clamping structure for clamping by the partition net feeding module. Then, the partition net feeding module drives the partition net clamping structure holding the partition net to align with the assembly gap and move toward the assembly platform. In the process of the partition net feeding module driving the partition net clamping structure to extend into the assembly gap, the partition net clamping structure pushes the middle part of the diaphragm into the assembly gap to achieve folding. At the same time, the partition net in the partition net clamping structure is embedded in the folded diaphragm to assemble into a diaphragm assembly. Finally, the diaphragm assembly discharging mechanism pulls the assembled diaphragm assembly out of the assembly gap for discharging. After the diaphragm assembly discharging mechanism pulls the partition net out of the assembly gap to a predetermined length, the partition net cutting module is used to cut the partition net to complete the processing of the diaphragm assembly. Thereafter, the partition net feeding mechanism is reset, and the above operation process is repeated to achieve continuous processing of the diaphragm assembly. The partition net clamping structure is used to push vertically downward to achieve folding of the middle part of the diaphragm, so that each diaphragm can be folded at the same position. At the same time, the partition net is accurately embedded in the folded diaphragm through the partition net clamping structure, thereby improving the processing and assembly accuracy between the diaphragm and the partition net, ensuring that the size of each diaphragm assembly is consistent, thereby improving the yield rate. At the same time, the assembly and discharging of the diaphragm assembly are carried out simultaneously, saving processing time, and having the effects of high processing accuracy, uniform size, and high processing efficiency.

[0012] The present invention is further configured as follows: the diaphragm assembly mechanism includes a diaphragm reel module, a diaphragm dragging module and a diaphragm cutting module for cutting the diaphragm, wherein the diaphragm dragging module is used to pull out the diaphragm in the diaphragm reel module and lay it on the assembly platform.

[0013] By adopting the above technical solution, during the assembly stage, the diaphragm dragging module is used to pull the diaphragm in the diaphragm roll module onto the assembly structure, so that the diaphragm is spread on the assembly structure and covers the assembly gap. During discharging, the diaphragm is pulled to the predetermined cutting position on the assembly structure through the diaphragm assembly discharging mechanism, and the diaphragm is cut by the diaphragm cutting module.

[0014] The present invention is further configured as follows: the diaphragm assembly discharging mechanism includes a transverse lifting module and a diaphragm assembly clamping assembly, the diaphragm assembly clamping assembly is used to clamp the fold connection of the diaphragm, and the transverse lifting module can drive the diaphragm assembly clamping assembly to move in space relative to the base station body to achieve discharging.

[0015] By adopting the above technical solution, the transverse lifting module drives the diaphragm assembly clamping assembly to move to the bottom of the assembly gap, and uses the diaphragm assembly clamping assembly to clamp the folded connection of the diaphragm. Then, the transverse lifting module pulls the assembled diaphragm assembly out of the assembly gap through the diaphragm assembly clamping assembly for discharge.

[0016] The present invention is further configured as follows: the assembly platform 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 a clamping block is provided at the end of the piston rod of the clamping cylinder.

[0017] By adopting the above technical solution, the width of the assembly gap can be adjusted by adjusting the relative positions of the first support platform and the second support platform. When the partition net feeding mechanism pushes the partition net into the assembly gap, the partition net is embedded in the folded membrane in the assembly gap. In the process of the partition net clamping structure clamping the partition net and moving it downward in the assembly gap, the rotating rollers on both sides can roll with the two side surfaces of the partition net clamping structure to prevent scratches from occurring when the lower end of the partition net clamping structure is inserted into the assembly gap, and at the same time, the smoothness of the downward movement of the partition net clamping structure is increased. During the loading process of the partition net, the partition net is clamped by the partition net clamping structure and extended into the assembly gap. Then the partition net clamping structure releases the clamping of the partition net, and at the same time the partition net sending module pushes the partition net to move downward for a certain distance relative to the partition net clamping structure, so that the fold connection between the partition net and the diaphragm is aligned. At this time, the pressing cylinder drives the clamping blocks on both sides to clamp the partition net part extending downward from the partition net clamping structure, so that the partition net will not bounce upward and leave the assembly gap under the action of the elastic tensioning mechanism during the rising process of the partition net clamping structure that is in a released state.

[0018] The present invention is further configured as follows: the diaphragm assembly clamping assembly comprises a plurality of clamping cylinders arranged side by side on the transverse movement and lifting module, and clamping ironing plates are arranged opposite to each other on the inner walls of the clamping jaws on both sides of the clamping cylinders.

[0019] By adopting the above technical solution, the clamping cylinder drives the clamping ironing plate to clamp the crease connection of the diaphragm assembly. At the same time, in the process of the transverse lifting module pulling the diaphragm assembly to discharge the material, the clamping ironing plate can be used to perform ironing welding on the crease connection of the diaphragm assembly, so that the diaphragm folded at both ends of the crease connection can be welded to the lower end of the partition net into one, so that the diaphragm assembly can be hot-welded simultaneously during the discharge process, thereby improving the processing efficiency of the diaphragm assembly.

[0020] The present invention is further configured as follows: the partition net sending module also includes a lifting drive structure that drives the partition net clamping structure to move up and down, and the lifting drive structure is provided with a driving roller assembly, and the driving roller assembly drives the partition net in the partition net drum module to be sent down to the partition net clamping structure.

[0021] By adopting the above technical solution, the driving roller assembly can drive the partition net down into the assembly gap, and the driving roller assembly can clamp the partition net. The present invention flexibly switches between the double clamping modes of the partition net by the driving roller assembly and the partition net clamping structure, so that the partition net will not be detached from the partition net feeding mechanism during the feeding process.

[0022] The present invention is further configured as follows: the partition mesh clamping structure includes a fixed clamping plate assembly and a movable clamping plate assembly which are relatively arranged on the lifting drive structure, and the lifting drive structure is provided with a horizontal thrust cylinder, and the horizontal thrust cylinder drives the movable clamping plate assembly to press against or move away from the fixed clamping plate assembly.

[0023] By adopting the above technical solution, the partition net can be clamped by the horizontal push cylinder pushing the movable clamping plate assembly close to the fixed clamping plate assembly, and the partition net can be released by retracting the piston rod of the horizontal push cylinder to make the movable clamping assembly away from the fixed clamping plate assembly.

[0024] The present invention is further configured as follows: the partition mesh cutting module includes a cutting knife and a screw rod substructure, the cutting knife is installed on the lifting drive structure through the screw rod substructure, and the cutting knife cuts the partition mesh laterally through the screw rod substructure.

[0025] The present invention is further configured as follows: a crease gluing mechanism is provided between the diaphragm feeding mechanism and the diaphragm assembly mechanism, and the crease gluing mechanism is used to stick adhesive tape to the crease connection of the diaphragm.

[0026] By adopting the above technical solution, the crease connection of the diaphragm is adhered with tape using the crease gluing mechanism, so that when the partition net lowering module presses the diaphragm down to the assembly gap, the crease connection of the diaphragm will not break due to excessive downward pressure stress.

[0027] The present invention is further configured as follows: a defective product rejection mechanism is also provided on the base station body, and the defective product rejection mechanism includes a visual inspection module, a multi-axis mechanical clamping module and a waste tray, and the visual inspection module is electrically connected to the multi-axis mechanical clamping module, and the visual inspection module is used to visually inspect defective diaphragms, and control the multi-axis mechanical clamping module to clamp and transport the defective diaphragms to the waste tray.

[0028] By adopting the above technical solution, when the visual inspection module detects that there are defects on the surface of the diaphragm, the multi-axis mechanical clamping module can be used to clamp the defective diaphragm and transport it to the waste tray for collection.

[0029] In summary, the present invention has the following beneficial effects:

The cutting knife 431 cuts the mesh 30 transversely through the screw rod substructure 432. The mesh lowering module 42 includes a mesh clamping structure 421. The mesh clamping structure 421 can switch between a clamping state and a release state relative to the mesh 30. The mesh lowering module 42 is used to push the mesh 30 in the mesh reel 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, and at the same time push the diaphragm 40 to be embedded in the assembly gap 21a to achieve folding; between the mesh reel module 41 and the mesh lowering module 42, the diaphragm reel module 31 and the diaphragm An elastic tensioning mechanism 7 is respectively provided between the dragging modules 32, and the elastic tensioning mechanism 7 always has the tendency to drive the corresponding partition net reel module 41 and the partition net delivery module 42, and the membrane reel module 31 and the membrane dragging module 32 to always maintain a movement tendency in a stretched state; and in this embodiment, a crease gluing mechanism 6 is provided between the membrane feeding mechanism 3 and the membrane component assembling mechanism 2, and the crease gluing mechanism 6 is used to stick tape on the crease connection of the membrane 40. The crease gluing mechanism 6 is used to stick tape on the crease connection of the membrane 40, so that in the process of the partition net delivery module 42 pressing the membrane down to the assembly gap 21a, the crease connection of the membrane 40 will not be caused by excessive downward pressure stress. causing breakage; a defective product rejection mechanism 8 is also provided on the base station body 1, and the defective product rejection mechanism 8 includes a visual inspection module 83, a multi-axis mechanical clamping module 81 and a waste tray 82, and the visual inspection module 83 is electrically connected to the diaphragm dragging module 32 and the multi-axis mechanical clamping module 81 respectively, and the visual inspection module 83 is used to visually inspect the defective diaphragm 40, and control the multi-axis mechanical clamping module 81 to clamp the defective diaphragm and transport it to the waste tray 82. When the visual inspection module 83 detects that there are defects on the surface of the diaphragm 40, it can feedback control the diaphragm dragging module 32 to suspend work, and at the same time use the multi-axis mechanical clamping module 81 to clamp the defective diaphragm 40 and transport it to the waste tray 82 for collection.

[0047] like Figure 11-12As shown, the assembly platform 21 includes a first support platform 211 and a second support platform 212 that are relatively arranged. The first support platform 211 and the second support platform 212 are relatively provided with rotating rollers 213. The assembly gap 21a is formed between the corresponding rotating rollers 213 on the first support platform 211 and the second support platform 212, and the first support platform 211 and the second support platform 212 are relatively provided with a clamping cylinder 214. The piston rod end of the clamping cylinder 214 is correspondingly provided with a clamping block 215. By adjusting the relative position of the first support platform 211 and the second support platform 212, the width of the assembly gap 21a can be adjusted. When the partition net feeding mechanism 4 pushes the partition net 30 into the assembly gap 21a, the partition net 30 is embedded in the folded membrane 40 in the assembly gap 21a. In the process of the partition net clamping structure 421 clamping the partition net 30 and moving downward in the assembly gap 21a, the rotating rollers 213 on both sides can be The rolling cooperation of the two side surfaces of the partition net clamping structure 421 can prevent the lower end of the partition net clamping structure 421 from being scratched when it is extended into the assembly gap 21a, and also increase the smoothness of the downward movement of the partition net clamping structure 421; during the partition net loading process, the partition net 30 is clamped by the partition net clamping structure 421 and extended into the assembly gap 21a, and then the partition net clamping structure 421 releases the clamping of the partition net, and at the same time, the partition net lowering module 42 pushes the partition net 30 to move downward a certain distance relative to the partition net clamping structure 421, so that the fold connection between the partition net 30 and the diaphragm 40 is aligned, and at this time, the pressing cylinder 214 drives the clamping blocks 215 on both sides to clamp the part of the partition net 30 extending downward from the partition net clamping structure 421, so that the partition net 30 will not bounce upward and disengage from the assembly gap 21a under the action of the elastic tensioning mechanism 7 during the ascending process of the partition net clamping structure that is in a released state with the partition net 30.

[0048] like Figure 8-9 As shown, a buffer structure is provided on the side of the assembly platform 21 facing the diaphragm assembly discharging mechanism 5, and the buffer structure includes a position adjustment module 216 and a roller 217 rotatably arranged on the position adjustment module 216. The diaphragm assembly discharging 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 maintain it at a suitable position, so that during the process of the diaphragm assembly discharging mechanism 5 pulling the diaphragm assembly to discharge, the outer surface of the diaphragm 40 can roll with the roller 217 to prevent the diaphragm 40 from rubbing against the assembly platform 21 and scratching the surface of the diaphragm 40.

[0049] like Fig.10As shown, the diaphragm assembly clamping assembly 52 includes a plurality of clamping cylinders 521 arranged side by side on the transverse moving and lifting module 51, and the inner walls of the clamping claws on both sides of the clamping cylinders 521 are relatively provided with clamping ironing plates 522. The clamping cylinders 521 drive the clamping ironing plates 522 to clamp the crease connection of the diaphragm assembly. At the same time, in the process of the transverse moving and lifting module 51 pulling the diaphragm assembly out of the material, the clamping ironing plates 522 can be used to hot-weld the crease connection of the diaphragm assembly, so that the diaphragm 40 folded at both ends of the crease connection can be welded to the lower end of the partition net 30, so that the diaphragm assembly can be hot-welded simultaneously during the process of discharging, thereby improving the efficiency of diaphragm assembly processing.

[0050] like Figure 4-7 As shown, the partition net sending module 42 also includes a lifting drive structure 422 that drives the partition net clamping structure 421 to move up and down. A driving roller assembly 423 is provided on the lifting drive structure 422. The driving roller assembly 423 is driven by a servo motor 4231 to achieve relative rotation. The relatively rotating driving roller assembly 423 drives the partition net to be sent down to the partition net clamping structure 421. The driving roller assembly 423 can drive the partition net to be sent down to the assembly gap 21a, and the driving roller assembly 423 can clamp the partition net 30. The present invention flexibly switches between the double clamping modes of the partition net 30 by the driving roller assembly 423 and the partition net clamping structure 421, so that the partition net 30 will not be separated from the partition net feeding mechanism 4 during the feeding process; the partition net clamping structure 421 includes a relatively arranged The fixed clamping plate assembly 4211 and the movable clamping plate assembly 4212 on the lifting drive structure 422 are provided with a horizontal pushing cylinder 4213. The horizontal pushing cylinder 4213 drives the movable clamping plate assembly 4212 to press against or move away from the fixed clamping plate assembly 4211. The horizontal pushing cylinder 4213 pushes the movable clamping plate assembly 4212 close to the fixed clamping plate assembly 4211 to clamp the partition net 30. The horizontal pushing cylinder 4213 retracts the piston rod to move the movable clamping assembly away from the fixed clamping plate assembly 4211 to release the partition net 30. In this embodiment, a clamping gap is left between the fixed clamping plate assembly 4211 and the movable clamping plate assembly 4212, and the clamping gap gradually decreases from the end away from the assembly platform 21 to the end close to the assembly platform 21.

[0051] The basic working principle of the present invention is as follows: during the assembly stage, the diaphragm dragging module 32 is used to pull the diaphragm 40 in the diaphragm reel module 31 onto the assembly platform 21. During the dragging process, the crease gluing mechanism 6 adheres tape to the crease connection in the middle of the diaphragm 40. Finally, the diaphragm dragging module 32 spreads the diaphragm 40 on the assembly platform 21, so that the crease connection of the diaphragm 40 is directly opposite to the assembly gap 21a. Then, the driving roller assembly 423 of the partition net lowering module 42 is used to push the partition net 30 in the partition net reel module 41 to the partition net clamping structure 421 for clamping, so that the lower end of the partition net 30 is slightly exposed from the lower end of the partition net clamping structure 421. Then, the partition net lowering module 42 drives the partition net clamping structure 421 that clamps the partition net 30 to align with the assembly gap 21a. When the partition net 30 moves toward the assembly platform 21 and the partition net lowering module 42 drives the partition net clamping structure 421 to extend into the assembly gap 21a, the lower end of the partition net 30 in the partition net clamping structure 421 pushes the tape at the fold connection into the assembly gap 21a, so that the diaphragm 40 is folded in half relative to the adhesive part at the fold connection. The pasted tape can prevent the cut end surface of the lower end of the partition net 30 from cutting the surface of the diaphragm 40, so that the partition net 30 located in the partition net clamping structure 421 is embedded in the folded diaphragm 40 to form a diaphragm assembly. Then the partition net clamping structure 421 releases the partition net and uses the driving roller assembly 423 to clamp the partition net 30. Then, the partition net lowering module 42 drives the partition net clamping structure 421 to lift upward relative to the partition net 30. When the partition net clamping structure 421 After moving up to a predetermined height, the partition net 30 is cut by the partition net cutting module 43, and then the partition net feeding mechanism 4 is reset, and at the same time, the diaphragm assembly clamping assembly 52 is used to clamp the lower end of the diaphragm assembly, so that the diaphragm 40 and the lower end of the partition net 30 are clamped by the diaphragm assembly clamping assembly 52, and then the transverse movement and lifting module 51 of the diaphragm assembly discharging mechanism 5 pulls the diaphragm assembly clamping assembly 52 to discharge the material. During the discharging process, the clamping ironing plate 522 on the diaphragm assembly clamping assembly 52 can be used to hot-weld the fold connection of the diaphragm assembly, so that the diaphragm 40 and the partition net 30 are welded into a diaphragm assembly as a whole, and when discharging, the transverse movement and lifting module 51 drives the diaphragm assembly clamping assembly 52 to pull the diaphragm assembly out of the assembly gap 21a, when it is close to the side of the diaphragm cutting module 33 When the diaphragm 40 is pulled out from the assembly gap 21a to the predetermined cutting position, the diaphragm cutting module 33 is used to cut the diaphragm 40, and the continuous processing of the diaphragm assembly is realized by repeating the above operation process. The present invention utilizes the partition net clamping structure 421 to drive the partition net 30 to push vertically downward to realize the folding of the middle part of the diaphragm 40, so that each diaphragm 40 can be folded at the same position. At the same time, the partition net 30 is accurately embedded in the folded diaphragm 40 through the partition net clamping structure 421, thereby improving the processing and assembly accuracy between the diaphragm 40 and the partition net 30, ensuring that the size of each diaphragm assembly is consistent, thereby improving the yield rate, and at the same time, the assembly and discharge of the diaphragm assembly are carried out synchronously, saving processing time, and having the effects of high processing accuracy, uniform size, and high processing efficiency.
