Description

Technical Field

[0001] This invention relates to the field of film core production technology for disc tube membranes, and more specifically, to a production line. Background Technology

[0002] Currently, disc tube membranes play a crucial role in wastewater softening treatment using existing technologies. In the production process of disc tube membranes, the filter membrane sheets and guide plates are typically stacked on a central tie rod. Then, the central tie rod and end flanges are fixed together, and finally, they are placed into a pressure-resistant membrane housing to complete the assembly of the disc tube membrane.

[0003] However, in existing disc tube membrane production lines, especially for the production of disc tube membrane cores, manual operation is the primary method. Specifically, during the stacking of filter membranes and guide discs onto the central tie rod, the stacking height typically reaches 1 meter. Because the actual assembly process requires repeated manual stacking, the labor intensity is high, assembly efficiency is low, and errors are easily made. Summary of the Invention

[0055] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0056] Please refer to Figures 1 to 2 In an embodiment of the present invention, a production line is provided for producing film cores for disc tube membranes. The production line includes: a positioning fixture plate 10, a conveying assembly 20, a first assembly unit 31, a stacking unit 40, and a second assembly unit 32. The conveying assembly 20 conveys the positioning fixture plate 10. The first assembly unit 31 is disposed on the side of the conveying assembly 20 and is used to assemble the center rod of the film core onto the positioning fixture plate 10. The stacking unit 40 is disposed on the side of the conveying assembly 20, downstream of the first assembly unit 31, and is used to stack the guide plates of the film core onto the center rod to complete the stacking process. The second assembly unit 32 is disposed on the side of the conveying assembly 20, downstream of the stacking unit 40, and is used to mount the upper flange of the film core onto the upper flange of the guide plate.

[0057] With this setup, by incorporating conveyor components 20, stacking units 40, and assembly units on the production line, the disc tube membrane production line can complete assembly and installation processes such as automatic loading of the center rod, stacking and assembling of the guide plate, and installation of the upper flange without relying on manual labor. This effectively reduces the intensity of manual labor, improves the production efficiency of the disc tube membrane core, and achieves automated assembly.

[0058] It should be noted that in this embodiment, relative to the conveying assembly, the first assembly unit 31 completes the process first, and then the stacking unit 40 performs the stacking process. Therefore, the stacking unit 40 can be understood as a downstream process of the first assembly unit 31. In addition, different positioning mechanisms are movably provided at different parts of the conveying assembly. The positioning of the positioning fixture plate 10 is achieved by the movement of different positioning mechanisms, thereby facilitating the completion of different processes.

[0059] In this embodiment, the first assembly unit 31 includes a first feeding component 311, a lubrication device 312, and a first assembly robot 313. The first feeding component 311 is used to convey and store the center rod, the lubrication device 312 stores lubricating oil for lubricating the center rod, and the assembly part of the first assembly robot 313 is movably configured. The assembly part of the first assembly robot 313 has a first working position for gripping the center rod on the first feeding component 311, a second working position for transferring the center rod to the lubrication device 312, and a third working position for installing the lubricated center rod on the positioning fixture plate 10. This configuration facilitates better storage of the center rod on the production line and its delivery to downstream processes, thereby improving the level of automation.

[0060] In this embodiment, the stacking unit 40 includes a second feeding component 41 and a stacking robot 42. The second feeding component 41 is used to convey and store guide trays, and the stacking section of the stacking robot 42 is movably configured to stack the guide trays on the second feeding component 41 onto the center rod via the stacking section. With this configuration, automated guide tray feeding can be achieved by replacing manual labor with robots, thereby enhancing the automation level of the production line.

[0061] Specifically, the production line also includes a counterweight unit 50, a detection unit 60, and a control unit. The counterweight unit 50 is located on the side of the conveying assembly 20 and has assembly and unloading states. When in the assembly state, the counterweight unit 50 is used to install counterweights onto the guide plates to press down multiple guide plates that have completed the stacking process. When in the unloading state, the counterweight unit 50 is used to remove counterweights from multiple guide plates and install upper flanges onto multiple guide plates via the second assembly unit 32. By setting up the counterweight unit 50, automated assembly and transportation of counterweights can be achieved, thereby improving the automation level of the production line. The detection unit 60 is located on the side of the conveying assembly 20 and is used to detect whether the scales on the guide plates equipped with counterweights are aligned. The detection unit 60 can replace traditional manual visual recognition, improving both the efficiency of the production line and the accuracy of recognition. Both the detection unit 60 and the counterweight unit 50 are connected to the control unit. When the detection unit 60 detects that the scale of the guide plate is aligned, the control unit controls the counterweight unit 50 to be in the unloading state. By setting the control unit, the system can automatically control the system's actions, reducing manual intervention and improving the automation level of the production line.

[0062] With this structural setup, by adding a counterweight to the guide plate after the stacking process, and through the counterweight assistance and detection by the detection unit 60, it is easy to effectively check whether the scale of the guide plate is aligned during the stacking process. This allows for adaptive operation of the guide plate after the stacking process based on the detection results of whether the scale is aligned.

[0063] Specifically, the production line also includes a rework conveyor unit 70. The rework conveyor unit 70 is located on the side of the conveying assembly 20 and is connected to the control unit. When the detection unit 60 detects misalignment of the guide plate's scale, the control unit controls the rework conveyor unit 70 to rework and transport the positioning fixture plate 10, which is equipped with a center rod, guide plate, and counterweight. The rework conveyor unit 70 replaces the manual separation and return of misaligned guide plates in traditional production lines, thus further improving the automation level of the production line.

[0064] In this embodiment, the counterweight unit 50 includes a third feeding component 51, a counterweight assembly robot 52, and a counterweight unloading robot 53. The third feeding component 51 is used to convey and store the counterweight blocks, and the counterweight section of the counterweight assembly robot 52 is movably configured. When the counterweight unit 50 is in the assembly state, the counterweight section of the counterweight assembly robot 52 is used to install the counterweight blocks on the guide plate. The unloading section of the counterweight unloading robot 53 is also movably configured, and when the counterweight unit 50 is in the unloading state, the unloading section of the counterweight unloading robot 53 is used to unload the counterweight blocks. With this configuration, the installation and disassembly of the counterweight blocks can be completed automatically by the counterweight assembly robot 52 and the counterweight unloading robot 53 without the need for manual installation and disassembly.

[0065] In this embodiment, the production line also includes a locking unit 80. The locking unit 80 is located downstream of the second assembly unit 32. The locking unit 80 is used to install the gaskets of the membrane core and lock the nut of the membrane core onto the center rod. The locking unit 80 can automate the disc tube membrane locking process, replacing manual labor.

[0066] Specifically, the fastening unit 80 includes a pressing mechanism 81, a second assembly robot 82, and a fastening robot 83. The pressing part of the pressing mechanism 81 is movably configured to press the upper flange mounted on the guide plate. The second assembly robot 82 is located on the side of the conveying assembly 20 and is used to install gaskets onto the upper flange. The fastening robot 83 is located on the side of the conveying assembly 20 and is used to lock nuts onto the center rod. With this configuration, the coordinated operation of the pressing mechanism 81, the second assembly robot 82, and the fastening robot 83 enables automated completion of gasket installation and overall locking of the disc tube membrane. Compared to manual operation, this configuration also improves production efficiency and assembly accuracy to a certain extent, ensuring assembly quality.

[0067] Specifically, the counterweight unit 50 includes a counterweight assembly robot 52 and a counterweight unloading robot 53. The conveying assembly 20 includes a first conveying section 21, a second conveying section 22, and a third conveying section 23.

[0068] The first conveying unit 21 can convey the positioning fixture plate 10 along the first conveying direction. The first assembly unit 31 is located on the side of the first conveying unit 21 and is used to assemble the center rod onto the positioning fixture plate 10 on the first conveying unit 21. This arrangement facilitates the automation of the center rod assembly process and improves the coordination between the first assembly unit 31 and the first conveying unit 21.

[0069] Alternatively, the second conveying unit 22 can convey the positioning fixture plate 10 along the second conveying direction. The stacking unit 40, the counterweight assembly robot 52, and the inspection unit 60 are located on the side of the second conveying unit 22. The stacking unit 40 is used to perform the stacking process on the positioning fixture plate 10 on the second conveying unit 22, and the counterweight assembly robot 52 is used to install the counterweights on the guide plate. This arrangement facilitates the automation of the stacking process and the installation of the counterweights, and also makes it easier to perform automated visual inspection on the stacked guide plates.

[0070] Alternatively, the third conveyor section 23 can convey the positioning fixture plate 10 along the third conveying direction. At least part of the counterweight unloading robot 53 and the locking unit 80 can be located on the side of the third conveyor section 23. The counterweight unloading robot 53 is used to unload the counterweight. In this way, after the counterweight unloading robot 53 disassembles the counterweight, the disc tube film to be locked can be transported to the locking unit 80 through the third conveyor section 23, which can effectively improve the efficiency of the production line and eliminate the need for manual intervention in the transfer of the disc tube film.

[0071] Alternatively, a first conveying unit 21, a second conveying unit 22, and a third conveying unit 23 can be set up at corresponding positions. Such a setup can maximize the automation level of the production line and improve the production and processing efficiency of the production line.

[0072] In this embodiment, the second conveying direction is set at a preset angle to the first conveying direction, and the third conveying direction is set at a preset angle to the second conveying direction. The conveying speed of the first conveying section 21 is greater than the conveying speed of the second conveying section 22. This arrangement can avoid material accumulation, reduce the waiting time of the first assembly unit 31, and improve the production efficiency of the production line.

[0073] The system comprises multiple second conveying sections 22, which are spaced apart along the conveying direction of the first conveying section 21. It also comprises multiple third conveying sections 23, each corresponding to one of the second conveying sections 22. This arrangement allows for the simultaneous assembly of multiple conveying sections, effectively improving production efficiency and thus increasing output.

[0074] In this embodiment, the reliability and flexibility of robots are utilized to connect various automated workstations. Then, combined with the production conveyor line, dual-line assembly is adopted to speed up the production cycle and improve production efficiency, thereby realizing the automated assembly and production of membrane cores.

[0075] Among them, the conveying assembly 20 can realize the positioning, conveying and cross-line conveying of tooling plates; the first assembly unit 31 can realize the automatic loading of the center rod from the tooling car to the tooling plate; the stacking unit 40 can realize the assembly of multiple guide plates to the center rod to a certain height, and use visual inspection to determine whether the scale of the guide plates is aligned; the counterweight unit 50 can realize the assembly, transportation and unloading of counterweights; the rework conveying unit 70 can detect whether the scale of the guide plates is aligned. If it is not aligned, it enters the rework line through the transplanting machine. After manual rework, it enters the conveying line to the next station; the second assembly unit 32 can realize the automatic assembly of the upper flange to the center rod; the locking unit 80 can realize the automatic assembly of the center rod gasket and the automatic locking of the center rod nut; the membrane core unloading unit 100 can realize the automatic unloading of the assembled membrane core.

[0076] The production process in this embodiment is as follows: The AGV trolley 90 transports the first feeding part 311 to the designated position, and the first assembly robot 313 places the center rod at the lubrication device 312 to lubricate the center rod, so as to facilitate the smooth assembly of the guide plate stack. After lubrication, it is placed on the positioning fixture plate 10 to complete the automatic loading of the center rod. Since the center rod loading speed is fast, it can avoid the situation of the first assembly robot 313 waiting or the accumulation of line material. At the same time, the use of dual lines for assembly can also improve the production cycle. Subsequently, the center rod is transported to two stacking units via the first conveyor unit 21 and positioned using a blocking mechanism. At one of the stacking assembly stations, the guide plates and membranes are pre-stacked and stored. The stacking robot 42 then grips and assembles them onto the center rod. After multiple gripping and assembly operations, the robot stops at a predetermined height on the center rod, completing the guide plate stacking assembly. Then, the counterweight assembly robot 52 assembles a counterweight to press down on the assembled guide plates, preventing misalignment of the guide plate's scale lines during transport. Before entering the upper flange assembly station, a visual inspection is performed to check whether all guide plate scales are aligned in a straight line. If the scales are aligned, the guide plates directly enter the upper flange assembly station and are positioned using a blocking mechanism. If the scales are not aligned, the guide plates are transported to the rework line via the rework transport unit 70 for manual rework and adjustment of the scales. After rework, the guide plates enter the lower and upper flange assembly station and are positioned using a blocking mechanism. The assembly process at the other stacking assembly station is the same as the assembly process at the other stacking assembly station. Then, the counterweight unloading robot 53 first removes the counterweight and places it on the third feeding part 51 for recycling. The second assembly unit removes the upper flange from the tooling car and assembles it on the center rod and presses it onto the guide plate. After the upper flange is assembled, it is moved to the locking unit 80 for blocking and positioning via the third conveyor 23. First, the upper flange is pressed by the gantry structure pressing mechanism 81. The second assembly robot 82 picks up the lubricated gasket and assembles it on the center rod. Then, the locking robot 83 picks up the lubricated nut and locks it on the center rod, completing the membrane core assembly. After the membrane core is assembled, it enters the membrane core unloading unit 100 for blocking and positioning. After passing through the membrane core unloading robot 101, it is automatically unloaded and placed on the buffer line 102 to wait for assembly with the shell. The entire automatic assembly production process of the membrane core includes the automatic production mode of the following stations: automatic center rod loading, guide plate stacking assembly, visual inspection, counterweight assembly and unloading, automatic upper flange assembly, automatic center rod gasket assembly, automatic center rod nut locking, and automatic membrane core unloading.

[0077] As can be seen from the above description, the above embodiments of the present invention achieve the following technical effects: by setting up a conveying component 20, a first assembly unit 31, a stacking unit 40 and a second assembly unit 32 on the production line, multiple processes can be automated, thereby improving the production efficiency of the production line and effectively reducing the intensity of manual labor, and solving the technical problem that the production line in the prior art cannot achieve automatic assembly.
