[0002] In the production process of water purifier filter cartridges, the welding and fixing of the non-woven fabric to the end caps is a crucial step. The main purpose of this step is to ensure the filter cartridge's sealing and filtration efficiency. The non-woven fabric, as a filtration medium, effectively intercepts impurities and particulate matter in the water, while the end caps serve to fix the non-woven fabric and seal the filter cartridge. By welding the two together, a strong connection between the non-woven fabric and the end caps is ensured, preventing leaks or reduced filtration efficiency due to connection problems during use, thus guaranteeing the water purifier's filtration performance and lifespan.

[0003] Currently, the welding process between end caps and nonwoven fabric mainly relies on manual operation. This production mode has the following problems: First, because this process requires high operational precision, and workers' skill levels vary, it is difficult to guarantee the stability of welding quality. Second, manual production is inefficient and has high labor costs, which cannot meet the needs of large-scale production. In addition, work-related accidents are prone to occur during manual operation, thereby increasing the safety management risks for enterprises. Utility Model Content

[0041] In the production process of water purifier filter cartridges, the welding and fixing of the non-woven fabric to the end caps is a crucial step. The main purpose of this step is to ensure the filter cartridge's sealing and filtration efficiency. The non-woven fabric, as a filtration medium, effectively intercepts impurities and particulate matter in the water, while the end caps serve to fix the non-woven fabric and seal the filter cartridge. By welding the two together, a strong connection between the non-woven fabric and the end caps is ensured, preventing leaks or reduced filtration efficiency due to connection problems during use, thus guaranteeing the water purifier's filtration performance and lifespan.

[0042] Currently, the welding process between end caps and nonwoven fabric mainly relies on manual operation. This production mode has the following problems: First, because this process requires high operational precision, and workers' skill levels vary, it is difficult to guarantee the stability of welding quality. Second, manual production is inefficient and has high labor costs, which cannot meet the needs of large-scale production. In addition, work-related accidents are prone to occur during manual operation, thereby increasing the safety management risks for enterprises.

[0043] In view of the above problems, this utility model provides a filter element end cap welding equipment, which aims to complete the welding and fixing process of the end cap and non-woven fabric in an automated manner, so as to improve the stability of welding quality and production efficiency, reduce labor costs and reduce work-related accidents.

[0044] Please see Figure 1 and Figure 2 The filter element end cap welding equipment provided in this embodiment includes:

[0045] The conveyor turntable 1 is rotatably connected to the workbench 2; the conveyor turntable 1 is arranged with a first loading station, a second loading station, a first welding station and an unloading station in a clockwise or counterclockwise direction around the axis;

[0046] The first feeding component 3 is located at the first feeding station and is used to supply the target end cap to the first feeding station.

[0047] The second feeding component 4 is located at the second feeding station; the second feeding component 4 is used to place the target nonwoven fabric on the target end cap in the second feeding station to form an end cap assembly.

[0048] The first welding assembly 5 is disposed at the first welding station; the first welding assembly 5 is used to perform the first welding operation on the end cap assembly in the first welding station.

[0049] The unloading component 6 is located at the unloading station and is used to unload the end cap components at the unloading station.

[0050] In this embodiment, the conveyor turntable 1 can be driven by a motor, which can be connected to the conveyor turntable 1 via gears, belts or other transmission devices to achieve precise speed control. The transmission device may include a cam divider, which can intermittently drive the conveyor turntable 1, so that the workpiece or material on the conveyor turntable 1 can sequentially reach each workstation as the conveyor turntable 1 rotates intermittently, and stay at the corresponding workstation for a preset time to perform the corresponding operation.

[0051] The positions of the first feeding assembly 3, the second feeding assembly 4, the first welding assembly 5, and the unloading assembly 6 are fixed and arranged circumferentially along the conveyor turntable 1. It can be understood that the first feeding station, the second feeding station, the first welding station, and the unloading station refer to the positions on the conveyor turntable 1 corresponding to the first feeding assembly 3, the second feeding assembly 4, the first welding assembly 5, and the unloading assembly 6, respectively. The positions of the first feeding station, the second feeding station, the first welding station, and the unloading station do not change with the rotation of the conveyor turntable 1. Through the rotation of the conveyor turntable 1, the workpieces or materials in the first feeding station can be sequentially transported to the second feeding station, the first welding station, and the unloading station. In subsequent descriptions, if other stations are involved, the positional relationship between these stations and the conveyor turntable 1 will refer to the above description and will not be repeated.

[0052] The first feeding assembly 3 may specifically include a transfer device such as a robotic arm to transfer the target end cap from the storage area to the first feeding station by means of clamping, suction, etc. The second feeding assembly 4 may specifically include a transfer device such as a robotic arm. When the target end cap of the first feeding station arrives at the second feeding station as the conveyor turntable 1 rotates, the transfer device of the second feeding assembly 4 may transfer the target nonwoven fabric from the storage area to the second feeding station by means of clamping, suction, piercing, twisting, etc., and place the target nonwoven fabric on the target end cap to form an end cap assembly.

[0053] The first welding component 5 can be an ultrasonic welding device. When the end cap component of the second feeding station arrives at the first welding station with the rotation of the conveyor turntable 1, the first welding component 5 can transmit high-frequency vibration waves to the target end cap surface and the target non-woven fabric surface in the end cap component and apply pressure to make the target end cap surface and the target non-woven fabric surface rub against each other to form a fusion between molecular layers, thereby achieving welding and fixing between the target end cap and the target non-woven fabric.

[0054] The unloading assembly 6 may include a transfer device such as a robotic arm. When the end cap assembly that has been welded in the first welding station arrives at the unloading station as the conveyor turntable 1 rotates, the transfer device of the unloading assembly 6 can transfer the end cap assembly at the unloading station to the collection area or the input end of the next process by means of clamping, suction, etc., so as to complete the unloading operation of the end cap assembly.

[0055] This embodiment utilizes the rotation of the conveyor turntable 1 between the first loading station, the second loading station, the first welding station, and the unloading station. The target end cap, continuously fed into the first loading station by the first loading component 3, can be sequentially transferred to each subsequent station. This allows the second loading component 4, the first welding component 5, and the unloading component 6 to continuously perform corresponding operations on the target end cap at the respective stations as the conveyor turntable 1 rotates intermittently. Thus, the bonding operation between the target end cap and the target nonwoven fabric, the first welding operation, and the unloading operation can be completed sequentially. The above solution completes the welding and fixing process between the end cap and the nonwoven fabric in an automated manner, avoiding the uncertainties caused by manual operation, improving the stability of welding quality and production efficiency, reducing labor costs, and reducing the occurrence of work-related accidents.

[0056] Preferably, the first loading station, the second loading station, the first welding station, and the unloading station are evenly arranged along the circumference of the conveyor turntable 1. This ensures that the intermittent rotation angle of the conveyor turntable 1 is a fixed angle. Whenever the conveyor turntable 1 rotates this fixed angle to transfer the target end cap or end cap assembly of any target station to the next station, the target end cap or end cap assembly of the previous station can also be transferred to the target station simultaneously. This ensures that the component corresponding to each station can perform the corresponding operation on the target end cap or end cap assembly at the corresponding station after each rotation of the conveyor turntable 1, thereby achieving continuous production, reducing the waiting time for each component to perform the corresponding operation at the corresponding station, and further improving production efficiency. It is understood that if other stations are added in the following embodiments, the added stations can be set to be evenly arranged along the circumference of the conveyor turntable 1 together with the first loading station, the second loading station, the first welding station, and the unloading station, which will not be described in detail later.

[0057] In one embodiment, refer to Figure 1 and Figure 2 The conveyor turntable 1 is also equipped with a tilting station, which is located between the first welding station and the unloading station.

[0058] The filter element end cap welding equipment also includes a flipping component 7, which is set at the flipping station and is used to flip the end cap assembly in the flipping station to a preset angle.

[0059] The flipping component 7 may specifically include a fixing mechanism and a flipping mechanism. The fixing mechanism is connected to the flipping mechanism. The fixing mechanism can use devices such as grippers and suction cups to perform clamping, suction and other fixing operations on the end cap assembly. The flipping mechanism can use a rotary cylinder or other driving device to flip the end cap assembly fixed on the fixing mechanism to a preset angle.

[0060] After the end cap assembly completes the first welding operation at the first welding station, the end cap assembly rotates with the conveyor turntable 1 to the flipping station. The flipping component 7 can flip the end cap assembly in the flipping station to a preset angle, so that the flipped end cap assembly can be welded in other directions to improve the welding quality between the target end cap and the target nonwoven fabric.

[0061] It is understandable that after the flipping component 7 flips the end cap assembly in the flipping station to a preset angle, the conveyor turntable 1 can continue to rotate in the original direction to convey the flipped end cap assembly to other welding stations between the flipping station and the unloading station for welding operations in other directions; the conveyor turntable 1 can also rotate in the opposite direction to return the flipped end cap assembly to the first welding station for welding operations in other directions; in actual applications, it can be flexibly set according to the production situation, and is not limited here.

[0062] In one embodiment, refer to Figure 1 and Figure 2 The conveyor turntable 1 is also equipped with a second welding station, which is located between the flipping station and the unloading station.

[0063] The filter element end cap welding equipment also includes a second welding assembly (not shown in the figure). The second welding assembly is set at the second welding station and is used to perform a second welding operation on the end cap assembly at the second welding station which is at a preset angle.

[0064] The second welding assembly can be made using ultrasonic welding equipment. When the end cap assembly that has been flipped in the flipping station arrives at the second welding station with the rotation of the conveyor turntable 1, the second welding assembly can transmit high-frequency vibration waves to the target end cap surface and the target non-woven fabric surface in the end cap assembly and apply pressure, so that the target end cap surface and the target non-woven fabric surface rub against each other to form a fusion between molecular layers, thereby achieving welding and fixing of the target end cap and the target non-woven fabric in other directions.

[0065] By adding a second welding station between the flipping station and the unloading station, after the flipping component 7 flips the end cap assembly in the flipping station to a preset angle, the conveyor turntable 1 can continue to rotate in the original direction. In this way, while completing the second welding operation on the flipped end cap assembly, the target end caps or end cap assemblies on other stations can also enter the next station for corresponding operations according to the original process. There is no need to rotate the conveyor turntable 1 in the opposite direction to make the end cap assembly return to the first welding station, thereby avoiding disrupting the operation process of other stations and ensuring that the welding process can be carried out continuously according to the normal production rhythm.

[0066] In one embodiment, refer to Figure 1 and Figure 2 The conveyor turntable 1 is also equipped with an inspection station, which is located between the first welding station and the unloading station.

[0067] The filter element end cap welding equipment also includes a vision inspection device 8, which is set at the inspection station and is used to inspect the welding quality of the end cap assembly at the inspection station.

[0068] The visual inspection device 8 may specifically include a visual sensing device and a welding quality inspection instrument. The visual sensing device can be used to collect image data of the welded parts on the end cap assembly and send it to the welding quality inspection instrument. The welding quality inspection instrument can process the acquired raw image data in real time and perform time-domain, frequency domain and image analysis on the data. For problems such as cracks, lack of fusion, incomplete penetration, slag inclusions, and porosity in the welded parts, it can achieve accurate detection, positioning, evaluation and diagnosis.

[0069] By setting up an inspection station, the welding quality of the welded end cap assemblies can be automatically inspected, which helps operators control the welding quality and promptly identify and remove end cap assemblies with welding problems before the material unloading operation.

[0070] It is understood that when the conveyor turntable 1 is provided with the second welding station in the above embodiment, the inspection station should be set between the second welding station and the unloading station.

[0071] In one embodiment, refer to Figure 1 and Figure 2 The unloading assembly 6 includes a sorting device 61, a first unloading trough 62, and a second unloading trough 63; the sorting device 61 is electrically connected to the vision inspection device 8, which is used to send a qualified signal or a failed signal to the sorting device 61 based on the welding quality inspection result.

[0072] The sorting device 61 is used to transfer the corresponding end cap assembly in the unloading station to the first unloading trough 62 when a qualified signal is received, and the sorting device 61 is used to transfer the corresponding end cap assembly in the unloading station to the second unloading trough 63 when a non-qualified signal is received.

[0073] By setting up a sorting device 61, the welded end cap assemblies can be automatically sorted according to the detection results of the vision inspection device 8, effectively separating end cap assemblies with good welding quality from those with poor welding quality. Specifically, the first feeding trough 62 can transport end cap assemblies with good welding quality to the collection area or directly use them in the next process; the second feeding trough 63 can transport end cap assemblies with poor welding quality to the recycling area for unified recycling. The above-mentioned automatic screening and sorting operation not only improves the automation and intelligence level of the filter element end cap welding equipment, but also ensures the high efficiency of the production process.

[0074] The visual inspection device 8 can preset corresponding threshold conditions for different welding data. When the welding data extracted by the visual inspection device 8 from the acquired image data meets the above threshold conditions, it can determine that the welding quality of the corresponding end cap assembly is good and send a qualified signal to the sorting device 61. When the welding data extracted by the visual inspection device 8 from the acquired image data does not meet the above threshold conditions, it can determine that the welding quality of the corresponding end cap assembly is poor and send a non-qualified signal to the sorting device 61. The sorting device 61 may specifically include a transfer device such as a robotic arm to transfer the end cap assembly from the unloading station to the first unloading trough 62 or the second unloading trough 63 by means of clamping, suction, etc.

[0075] In one embodiment, refer to Figure 1 and Figure 2The first feeding component 3 includes a vibratory feeder 31 and a feeding and transfer mechanism 32. The vibratory feeder 31 is used to transport the target end caps to the picking area in sequence, and the feeding and transfer mechanism 32 is used to pick up the target end caps in the picking area to the first feeding station in sequence.

[0076] Specifically, the vibratory feeder 31 can automatically arrange the bulk target end caps into an orderly single row and continuously transport them to the picking area, so that the loading and transfer mechanism 32 can sequentially clamp each target end cap in the picking area to the first loading station, thereby achieving orderly and precise loading of the target end caps. The loading and transfer mechanism 32 may include a transfer device such as a robotic arm, which can use the gripper at the end of the robotic arm to clamp the target end caps from the picking area to the first loading station.

[0077] In one embodiment, refer to Figure 1 and Figure 2 The second feeding assembly 4 includes a nonwoven fabric storage rack 41 and a needle-punching gripping mechanism 42. The nonwoven fabric storage rack 41 stores the target nonwoven fabric. The needle-punching gripping mechanism 42 is used to transfer the target nonwoven fabric to the target end cap in the second feeding station by penetrating the target nonwoven fabric with a picking needle.

[0078] The needle-punching gripping mechanism 42 can change the angle and depth of needle punching according to the thickness of the target nonwoven fabric by altering the setting parameters of the drive and transmission mechanisms, thereby achieving accurate material picking. This solves the problem of unstable material picking caused by differences in the specifications and thickness of the target nonwoven fabric, making it adaptable to different application scenarios and highly flexible. The specific working method and principle of the needle-punching gripping mechanism 42 can be found in existing technologies and will not be elaborated here.

[0079] In one embodiment, refer to Figure 1 and Figure 2 The filter element end cap welding equipment also includes a dust collection device, which is installed on the conveyor turntable 1 and is used to perform dust collection operations on the target area on the conveyor turntable 1.

[0080] By installing a dust collection device, dust, lint, dirt and other impurities generated during the production process can be removed to maintain a clean working environment and prevent these impurities from adversely affecting the normal progress of the welding process.

[0081] In one embodiment, refer to Figure 1 and Figure 2The filter element end cap welding equipment also includes a control panel 9. The control panel 9 is electrically connected to at least the conveyor turntable 1, the first feeding component 3, the second feeding component 4, the first welding component 5, and the unloading component 6. The control panel 9 is used to send control signals to at least one of the conveyor turntable 1, the first feeding component 3, the second feeding component 4, the first welding component 5, and the unloading component 6, and to receive and display feedback signals sent by at least one of the conveyor turntable 1, the first feeding component 3, the second feeding component 4, the first welding component 5, and the unloading component 6.

[0082] By setting up control panel 9, operators can easily interact with various components or modules in the filter element end cap welding equipment. Operators can input control signals via touch to manually operate the corresponding components or modules. Operators can also obtain production data fed back by various components or modules through the display device on control panel 9, thereby enabling real-time control of production information and facilitating the storage, backup, and export of relevant production data.

[0083] It is understood that when the filter end cap welding equipment includes the flipping component 7, the second welding component, the visual inspection device 8, the sorting device 61, and the dust collection device in the above embodiments, the flipping component 7, the second welding component, the visual inspection device 8, and the dust collection device can be electrically connected to the control panel 9 to receive control signals sent by the operator through the control panel 9 and send corresponding feedback signals to the control panel 9.

[0084] In one embodiment, refer to Figure 1 and Figure 2 The conveyor turntable 1 is equipped with multiple positioning fixtures 11, which are respectively set at the first loading station, the second loading station, the first welding station, and the unloading station. The positioning fixtures 11 are used to fix the target end cap placed in the first loading station.

[0085] The positioning fixture 11 can fix the target end cap or end cap assembly at each station through snap-fit ​​connection, locking, negative pressure adsorption and other methods, so that the target end cap or end cap assembly maintains a stable position and posture during the subsequent welding process and transportation process, reduces errors and improves the welding processing accuracy.

[0086] In one embodiment, refer to Figure 1 and Figure 2 The filter element end cap welding equipment also includes a machine cover 10, which is used to accommodate at least the conveyor turntable 1, the first feeding assembly 3, the second feeding assembly 4, the first welding assembly 5, and the unloading assembly 6.

[0087] By providing a cover 10, the corresponding components or modules in the filter element end cap welding equipment can be protected, and the appearance of the filter element end cap welding equipment can be improved. It is understood that when the filter element end cap welding equipment includes the flipping component 7, the second welding component, the visual inspection device 8, the dust collection device, and the control panel 9 in the above embodiments, the flipping component 7, the second welding component, the visual inspection device 8, and the dust collection device can be correspondingly arranged inside the cover 10, and the control panel 9 can be arranged on the outer wall of the cover 10.
