[0056] The filter shell transfer device 112 is used to transfer the target filter shell 100 on the filter shell loading device 111 to the first positioning fixture 114, the positioning clamp 115 is used to clamp and position the target filter shell 100 in the first positioning fixture 114, and the filter shell conveying device 113 is used to convey the target filter shell 100 in the first positioning fixture 114 to the welding station 21.

[0057] Specifically, the filter housing loading device 111 and the filter housing conveying device 113 may include a driving device and a transmission mechanism; the driving device may be powered by a motor, a hydraulic component, a pneumatic component, etc.; the transmission mechanism may include transmission devices such as belts, rollers, gears, and chains, and the transmission mechanism is used to convert the driving action of the driving device into a movement along a preset path; based on the above settings, after the target filter housing 100 in the storage area is loaded onto the filter housing loading device 111, the filter housing loading device 111 may convey multiple target filter housings 100 to the filter housing conveying device 113, and then the filter housing conveying device 113 sequentially conveys the multiple target filter housings 100 to subsequent operating stations. Among them, the conveying direction of the filter housing loading device 111 is different from that of the filter housing conveying device 113 to avoid occupying too much space in a single direction.

[0058] The filter housing transfer device 112 may include mechanical arms, clamps, suction cups, hangers and other devices that fix the target filter housing 100 by clamping, snap-fitting, pinning, negative pressure adsorption and other methods; the filter housing transfer device 112 may also drive the fixed target filter housing 100 to complete translation, flipping and other actions within a certain degree of freedom based on the cooperation between the above devices and driving components such as motors, speed reduction mechanisms, and rotary cylinders. Based on the above settings, the target filter housings 100 that are not uniformly arranged and are relatively scattered on the filter housing feeding device 111 can be transferred to the first positioning fixture 114 on the filter housing conveying device 113 in sequence according to certain placement requirements through the filter housing transfer device 112, so that each target filter housing 100 maintains the same posture and ensures that there is a certain distance between each target filter housing 100, so that the operation space can be reserved, so that multiple target filter housings 100 can better complete the subsequent accessories welding, filter material loading and other operations during the conveying and transfer process of the filter housing conveying device 113.

[0061] Specifically, the labeling device 32 can take out the label from the label roll or label box, and separate the label from the base paper through a peeling plate, peeling wheel and other mechanisms, and then accurately position the peeled label to the target position on the surface of the target filter element assembly 400 through a mechanical positioning system or a visual positioning system, and then tightly adhere the label to the surface of the target filter element assembly 400 through a pressure roller, a pressure-sensitive device, etc., and ensure that the label is firmly adhered through heating operation or a pressure curing device.

[0062] The code scanning device may include a scanning head and a data processing unit, which can quickly read the QR code or barcode information on the label, convert it into a digital signal and send it to the storage module for data entry and storage, thereby realizing automatic identification and recording of the information of the target filter element assembly 400. The code scanning device can realize automatic identification of the filter element without manual intervention, thereby improving production efficiency; and by entering the identified label information into the production management system, the workload of manual input can be reduced, the data error rate caused by human operation errors can be reduced, and a unique identification code is provided for each filter element, which is convenient for subsequent quality tracking and product traceability, and enhances the reliability and safety of the product; in addition, through real-time scanning and data entry, the flow of filter elements on the production line can be monitored, abnormalities in the production process can be discovered in time, and the intelligent level of production management can be improved.

[0063] In one embodiment, reference Figure 1 and Figure 2 The pre-installation equipment 1 also includes an accessory loading component 14, an accessory transfer component and a second welding component 15; the output end of the accessory loading component 14 is connected to the filter shell conveying component 11, the accessory transfer component is used to transfer the target accessory on the accessory loading component 14 to the target filter shell 100 on the filter shell conveying component 11, and the second welding component 15 is used to perform a second welding operation on the target filter shell 100 and the target accessory on the filter shell conveying component 11.

[0064] Specifically, the target accessories include but are not limited to end caps, covers, connectors, sealing devices, pipeline devices, etc. The accessory loading assembly 14 may include a driving device and a transmission mechanism; the driving device may be powered by a motor, a hydraulic component, a pneumatic component, etc.; the transmission mechanism may include transmission devices such as belts, rollers, gears, and chains, and the transmission mechanism is used to convert the driving action of the driving device into movement along a preset path; through the cooperation of the driving device and the transmission mechanism, multiple target accessories can be driven to move along the preset path, thereby completing the loading operation of multiple target accessories.

[0065] The accessory transfer assembly may include mechanical arms, clamps, suction cups, hangers and other devices that fix the target accessories by clamping, snap-fitting, pinning, negative pressure adsorption and other methods; the accessory transfer assembly can also drive the fixed target accessories to complete translation, flipping and other actions within a certain degree of freedom based on the cooperation between the above-mentioned devices and driving components such as motors, speed reduction mechanisms, and rotary cylinders. In this way, before the filter material transfer assembly 13 loads the target filter material 200 into the inner cavity of the target filter housing 100, the accessory transfer assembly can take out the target accessories output by the accessory loading assembly 14 in sequence and correspond one by one to the corresponding positions of the target filter housing 100 pre-installed on the filter housing conveying assembly 11.

[0066] The second welding assembly 15 can adopt an ultrasonic welding device 2. The second welding assembly 15 can transmit high-frequency vibration waves to the surfaces of the pre-installed target accessories and the target filter housing 100, and apply pressure to make the surface of the target accessories and the surface of the target filter housing 100 rub against each other to form fusion between the molecular layers, thereby achieving welding and fixation between the target accessories and the target filter housing 100.

[0067] Based on the scheme of this embodiment, before the installation operation of the target filter material 200 and the target filter housing 100, the installation and welding fixing operation between the target accessory and the target filter housing 100 can be completed in an automated manner, thereby further improving the degree of automation of the filter element production system, thereby further improving production efficiency and reducing labor costs.

[0068] In one embodiment, reference Figure 1 and Figure 2 The pre-installation equipment 1 also includes a visual inspection device 16, which is arranged at the output end of the accessory loading component 14, and the visual inspection device 16 is electrically connected to the accessory transferring component; the visual inspection device 16 is used to perform quality inspection on the target accessory on the accessory loading component 14, and send an accessory qualified signal to the accessory transferring component when the quality inspection passes; the accessory transferring component is used to transfer the target accessory to the target filter shell 100 on the filter shell conveying component 11 when receiving the accessory qualified signal.

[0069] The visual inspection device 16 may specifically include an image acquisition module and a back-end image analysis module. The image acquisition module is used to acquire image data of the target accessory and send it to the image analysis module. The image analysis module may perform pre-processing operations such as denoising, graying, and edge enhancement on the acquired original image data, and then perform segmentation and feature extraction on the pre-processed image. Then, the specific objects in the extracted features are compared with preset threshold conditions through methods such as neural networks to determine whether the target accessory has surface defects, specification errors, etc.; if it is finally determined that the quality of the target accessory meets the preset conditions, an accessory qualified signal may be sent to the accessory transfer component based on the detection and recognition results to trigger the accessory transfer component to transfer the qualified target accessory from the output end of the accessory loading component 14 to the target filter shell 100 of the filter shell conveying component 11; and if the target accessory is unqualified, the quality inspection result is failure. At this time, the unqualified target accessory may be transferred to the recycling area through the corresponding drive device, or shut down and manually intervened.

[0070] Based on the above arrangement, the quality of the target accessories can be inspected and evaluated before the installation operation of the target accessories and the target filter housing 100 is performed, and subsequent installation operations can be performed while ensuring that the target accessories are qualified, thereby preventing target accessories with quality problems from flowing into the subsequent production process with the target filter housing 100 and causing adverse effects on the final product quality, and target accessories with quality problems can be discovered and eliminated in a timely manner.

[0072] Specifically, the first flipping mechanism 17 may include a mechanical arm, a clamp, a suction cup, a hanger, or other devices for fixing the target filter housing 100 by clamping, snapping, pinning, negative pressure adsorption, or the like; the first flipping mechanism 17 may also be based on the cooperation between the above-mentioned devices and driving components such as motors, reduction mechanisms, and rotary cylinders, so as to drive the fixed target filter housing 100 to complete the flipping action within a certain degree of freedom, so that the opening of the target filter housing 100 faces the filter material loading direction of the filter material transfer assembly 13, thereby making it easier for the filter material transfer assembly 13 to load the target filter material 200 into the inner cavity of the target filter housing 100.

[0073] By setting the first flipping mechanism 17 between the second welding assembly 15 and the filter material transfer assembly 13, the position of the target filter housing 100 can be adjusted after the target filter housing 100 and the target accessory are welded and fixed, so as to adjust the placement angle of the target filter housing 100 during the welding process to an angle that is more convenient for the target filter material 200 to be installed, thereby avoiding interference, jamming and other problems during the installation of the target filter material 200.

[0077] The inspection and transfer assembly 51 may include a driving device, a transmission mechanism and a positioning mechanism; the driving device may be powered by a motor, a hydraulic assembly, a pneumatic assembly, etc.; the transmission mechanism may include transmission devices such as belts, rollers, gears, chains, etc., and the transmission mechanism is used to convert the driving action of the driving device into movement along a preset path; the positioning mechanism may be set to multiple and connected to the transmission mechanism, and the positioning mechanism may include clamps, suction cups, hangers, etc., to fix the target filter element assembly 400 by clamping, snap-on, pinning, negative pressure adsorption, etc., so that multiple target filter element assemblies 400 can be driven by the transmission mechanism to move along the preset path and be transferred from the welding station 21 to the inspection station 52 in turn for quality inspection, and after the quality inspection is completed, they are transferred to the marking device 3 in turn.

[0078] The inspection station 52 can inspect the quality of the welded target filter element assembly 400 by image analysis and other methods. Taking welding quality inspection as an example, after collecting the image data of the welding part between the target filter element cover 300 and the target filter housing 100, the inspection station 52 can send the image data to the welding quality inspection instrument. The welding quality inspection instrument can process the acquired original image data in real time, perform time-domain, frequency-domain and image analysis on the data, and can realize accurate inspection, positioning, evaluation and diagnosis of cracks, lack of fusion, lack of penetration, slag inclusions, pores and other problems in the welding part.

[0079] By setting up the inspection station 52, the welded target filter element assembly 400 can be automatically inspected before the marking operation, thereby helping the operator to control the quality of the target filter element assembly 400 and promptly discover and eliminate the target filter element assembly 400 with quality problems.

[0082] This embodiment can automatically sort the target filter element components 400 according to the quality inspection results of the inspection station 52, and can effectively screen the target filter element components 400 with good quality and the target filter element components 400 with poor quality; specifically, the target filter element components 400 with good quality can be directly transported to the marking device 3 for subsequent marking operations, while the target filter element components 400 with poor quality are transported to the recycling bin 6 for unified recycling. The above-mentioned automatic screening and sorting operation process not only improves the automation and intelligence level of the filter element production system, but also ensures the high efficiency of the production process.

[0083] Among them, the detection station 52 can preset corresponding threshold conditions based on various types of data of the target filter element assembly 400 collected; taking the determination of welding quality by image data as an example, when the welding data extracted by the detection station 52 from the collected image data meets the above threshold conditions, it can be determined that the welding quality of the corresponding target filter element assembly 400 is good and send a filter element qualified signal to the detection transfer assembly 51; when the welding data extracted by the detection station 52 from the collected image data does not meet the above threshold conditions, it can be determined that the welding quality of the corresponding target filter element assembly 400 is poor and send a filter element unqualified signal to the detection transfer assembly 51. In the process of conveying the target filter element assembly 400 to the marking device 3, when passing through the recovery bin 6, the detection transfer assembly 51 can directly put the target filter element assembly 400 with poor quality into the recovery bin 6.

[0084] In one embodiment, reference Figure 1 and Figure 2 The marking device 3 includes a marking device 31 and a labeling device 32; the marking device 31 includes a marking conveying component 311 and a laser marking device 312, and the labeling device 32 includes a labeling conveying component 321 and a labeling device 322.

The laser marking device 312 can focus the laser beam through the corresponding optical components. When the laser beam is focused on the surface of the target filter element assembly 400, the high energy of the laser causes the material to heat up locally rapidly, causing the surface of the material to evaporate, melt or produce a chemical reaction, so that the desired pattern, text and symbol can be formed on the surface of the target filter element assembly 400 to complete the marking operation.

[0087] The labeling conveying assembly 321 may include a driving device, a transmission mechanism and a positioning mechanism; the driving device may be powered by a motor, a hydraulic assembly, a pneumatic assembly, etc.; the transmission mechanism may include transmission devices such as belts, rollers, gears, chains, etc., and the transmission mechanism is used to convert the driving action of the driving device into movement along a preset path; the positioning mechanism may be provided in multiple forms and connected to the transmission mechanism, and the positioning mechanism may include clamps, suction cups, hangers, etc., so as to fix the target filter element assembly 400 by clamping, snap-fitting, pinning, negative pressure adsorption, etc., so that multiple target filter element assemblies 400 that have completed the marking operation can be driven by the transmission mechanism to move along the preset path and be transferred from the output end of the labeling conveying assembly 311 to the labeling device 322 in sequence. The labeling device 322 will take out the label from the label roll or label box, and separate the label from the base paper through a peeling plate, peeling wheel and other mechanisms, and then accurately position the peeled label to the target position on the surface of the target filter element assembly 400 through a mechanical positioning system or a visual positioning system, and then tightly adhere the label to the surface of the target filter element assembly 400 through a pressure roller, a pressure-sensitive device, etc., and can ensure that the label is firmly adhered through heating operation or a pressure curing device, thereby completing the labeling operation and forming a finished filter element; the finished filter element can be output from the output end of the labeling conveying assembly 321 to the discharging device 4 for unloading operation.

[0089] Specifically, the second flipping mechanism 53 may include a mechanical arm, a clamp, a suction cup, a hanger, or other devices that fix the target filter element assembly 400 by clamping, snapping, pinning, negative pressure adsorption, etc.; the second flipping mechanism 53 can also drive the fixed target filter element assembly 400 to complete the flipping action within a certain degree of freedom based on the cooperation between the above-mentioned devices and the driving components such as the motor, the reduction mechanism, and the rotary cylinder, so that the target filter element assembly 400 is flipped from the vertical posture during the first welding operation to the horizontal posture, so as to facilitate the target filter element assembly 400 in the horizontal posture to be placed in the preset positioning fixture of the inspection station 52 in sequence for positioning, so as to complete the subsequent quality inspection operation.

[0095] After the target filter element assembly 400 enters the detection equipment 5, the target filter element assembly 400 is clamped by the second flipping mechanism 53, and the target filter element assembly 400 is flipped from the vertical position during the first welding operation to the horizontal position, and then the flipped target filter element assembly 400 is placed in the detection station 52 under the drive of the detection transfer assembly 51 to perform quality inspection on the target filter element assembly 400; when the quality inspection result is unqualified, the detection station 52 will send a filter element unqualified signal to the detection transfer assembly 51 to trigger the detection transfer assembly 51 to transport and transfer the unqualified target filter element assembly 400 to the recovery bin 6 for unified recovery and record the bad data; when the quality inspection result is qualified, the detection station 52 will send a filter element qualified signal to the detection transfer assembly 51 to trigger the detection transfer assembly 51 to transport and transfer the qualified target filter element assembly 400 to the rear-end marking device 3.

[0096] When the qualified target filter element assembly 400 enters the marking device 31, the marking conveying assembly 311 will drive the target filter element assembly 400 to transfer to the laser marking device 312 for marking operation, and then the marking conveying assembly 311 will convey the marked target filter element assembly 400 to the rear-end labeling device 32; when the target filter element assembly 400 enters the labeling device 32, the labeling conveying assembly 321 will drive the target filter element assembly 400 to transfer to the labeling device 322 for labeling operation; the target filter element assembly 400 will form a finished filter element after labeling, and the labeling conveying assembly 321 can convey the finished filter element to the discharging device 4, so as to unload the finished filter element through the discharging device 4, and convey the finished filter element to the collection area or directly use it in the next process.
