Description

TECHNICAL FIELD

[0001] The application relates to the technical field of filter core processing, in particular to a filter core strip pasting device. BACKGROUND

[0002] In the filter core production process, the filter core strip pasting operation is a key link to ensure the structural integrity and sealing performance of the filter core. The existing filter core strip pasting device usually directly transfers the initial filter core to the pasting station for edge strip pasting, but lacks a precise adjustment mechanism for the position of the filter core. Due to the influence of mechanical vibration, material deformation or manufacturing tolerance during the feeding and transferring of the filter core, the initial filter core may be offset at the edge strip pasting position. This offset makes the edge strip unable to accurately align with the side edge of the filter core, resulting in uneven pasting, edge strip wrinkling or local delamination. As a result, the sealing performance of the filter core is reduced, which may cause problems such as leakage of the filter medium and insufficient structural strength, thereby affecting the service life and filtering efficiency of the filter core. In addition, the position deviation also increases the waste of edge strip material and the subsequent rework cost, and reduces the overall production efficiency. In view of the above problems, the existing technology needs to be improved.

[0003] In view of the above problems, the existing technology needs to be improved. SUMMARY

[0025] The following description is presented to enable any person skilled in the art to practice the application as claimed. In the following description, for purposes of explanation, specific details are set forth to provide a thorough understanding of the application. It will be apparent to one skilled in the art, however, that the application can be practiced without using these specific details. In other instances, well-known processes have not been elaborated as not to unnecessarily obscure the description of the embodiments of the application. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0026] The conventional filter core strip pasting device lacks a filter core position correction mechanism before pasting the filter core, resulting in low strip pasting accuracy.

[0027] Please refer to Figures 1-2 The filter core strip pasting device 1000 includes a filter core feeding mechanism 100, a filter core correction mechanism 200, and a pressure maintaining mechanism 300. The filter core feeding mechanism is used to carry an initial filter core and transfer the initial filter core to a side strip pasting position along a first direction X. The filter core correction mechanism 200 is located on one side of the filter core feeding mechanism 100 and is used to correct the position of the initial filter core. The pressure maintaining mechanism 300 is located on one side of the filter core correction mechanism 200 and the initial filter core and is used to apply pressure to the pasted filter core side strip, so that the filter core side strip is pasted with the initial filter core to obtain a filter core.

[0028] For ease of understanding, some key terms in the present embodiment are explained as follows: The filter core feeding mechanism 100 is used to carry the initial filter core to be processed and transport it to the subsequent processing position according to the preset path and direction. The filter core feeding mechanism 100 ensures that the initial filter core can enter the strip pasting process stably and accurately.

[0029] The initial filter core refers to the filter core body that has not been subjected to side strip pasting processing. It usually has a specific shape and size and is the object of the side strip pasting operation of the device.

[0030] The first direction X refers to the main direction in which the initial filter core moves from the feeding position to the side strip pasting position in the filter core strip pasting device 1000. The first direction X defines the transmission path of the initial filter core.

[0031] The side strip pasting position refers to a specific spatial position where the initial filter core and the filter core side strip are subjected to pasting operation. At this position, the filter core side strip is accurately applied to the designated side of the initial filter core.

[0032] The filter core correction mechanism 200 is used to adjust the position and posture of the initial filter core when it reaches the side strip pasting position, so as to eliminate possible deviations and ensure that the initial filter core is in the accurate pasting position.

[0033] The pressure maintaining mechanism 300 is used to apply continuous and stable pressure to the bonding area after the filter core edge strip is attached to the initial filter core. This pressure helps to promote the firm adhesion between the filter core edge strip and the initial filter core, improving the bonding quality.

[0034] The filter core edge strip refers to a strip-shaped material used to attach to the side edge of the initial filter core, which usually has adhesion or can be bonded by heating, pressing or other methods.

[0035] The filter core refers to a finished or semi-finished filter core with complete structure and function after the filter core edge strip bonding process.

[0036] Specifically, the filter core feeding mechanism 100 is configured to carry the initial filter core and transfer it to the edge strip bonding position along the first direction X. As an implementation, the filter core feeding mechanism 100 can include a conveyor belt system that moves the conveyor belt by driving motor, thereby conveying the initial filter core placed on the conveyor belt from the feeding end to the edge strip bonding position. In another implementation, the filter core feeding mechanism 100 can use a push rod or a mechanical arm to move the initial filter core from one position to another by reciprocating or grasping the placement until it reaches the edge strip bonding position. In another implementation, the filter core feeding mechanism 100 can use a driving element, a sliding rail and a sliding block to move the initial filter core from one position to another until it reaches the edge strip bonding position.

[0037] The filter core correction mechanism 200 is arranged on one side of the filter core feeding mechanism 100, and its function is to correct the position of the initial filter core. Specifically, the filter core correction mechanism 200 can include a set of fixed or adjustable sub-correction elements that, when the initial filter core is conveyed near the edge strip bonding position, push it to the pre-set accurate position by contacting the side edge of the initial filter core. As another implementation, the filter core correction mechanism 200 can use a cylinder-driven clamping device that, after the initial filter core reaches the designated area, positions and corrects it by clamping a specific part of the initial filter core.

[0038] The pressure maintaining mechanism 300 is arranged on one side of the filter core correction mechanism 200 and the initial filter core, and is used to apply pressure to the attached filter core edge strip to make the filter core edge strip bond with the initial filter core, and finally obtain the filter core. For example, the pressure maintaining mechanism 300 can be composed of a pair of parallel pressure plates that move inward under pneumatic or hydraulic drive to apply uniform pressure to the bonding area of the filter core edge strip and the initial filter core after the filter core edge strip is initially attached to the initial filter core, to promote the solidification and adhesion of the colloid. In another implementation, the pressure maintaining mechanism 300 can use a roller structure, and the roller rolls over the bonding area to apply pressure to the attached filter core edge strip by rolling to ensure that it is tightly bonded with the initial filter core.

[0039] To sum up, the filter core strip pasting device 1000 of the embodiment realizes accurate feeding, position correction and firm pasting of the initial filter core by setting the filter core feeding mechanism 100, the filter core correction mechanism 200 and the pressure maintaining mechanism 300. The introduction of the filter core correction mechanism 200 effectively solves the problem of low strip pasting accuracy caused by position deviation of the filter core in the traditional device, ensures that the filter core strip can be accurately and correctly pasted on the specified position of the initial filter core, and thus improves the pasting quality and production efficiency of the filter core strip.

[0040] Please refer to Figure 3 and Figure 4 In some embodiments of the present application, the first feeding mechanism includes a first feeding assembly 101 and a second feeding assembly 102, and the first feeding assembly 101 and the second feeding assembly 102 respectively carry the initial filter core and alternately transfer the initial filter core to the strip pasting position to alternately perform strip pasting.

[0041] In some embodiments of the present application, after the initial filter core carried by the first feeding assembly 101 completes strip pasting, the first feeding assembly 101 is further used to transfer the filter core from the strip pasting position to the specified position; and the second feeding assembly 102 is further used to transfer another initial filter core to the strip pasting position after the first feeding assembly 101 transfers the filter core from the strip pasting position, so as to perform next strip pasting on the initial filter core.

[0042] Specifically, the first feeding assembly 101 and the second feeding assembly 102 can respectively adopt the mode of mechanical arm cooperating with suction cup or clamp to realize grasping and placing of the initial filter core, or adopt a sliding connecting piece with filter core tray to convey the filter core to the specified position through a guide rail.

[0043] After completing strip pasting, the first feeding assembly 101 is used to transfer the filter core from the strip pasting position to the specified position, and the purpose is to move the filter core that has completed strip pasting out of the working area to free up space for subsequent operations. For example, the first feeding assembly 101 can place the filter core on the discharge conveyor belt or stack it in the collection box.

[0044] After the first feeding assembly 101 transfers the filter core from the strip pasting position, the second feeding assembly 102 is used to transfer another initial filter core to the strip pasting position to perform next strip pasting on the initial filter core. This ensures the continuity of the strip pasting process. For example, when the first feeding assembly 101 is unloading the filter core that has been pasted, the second feeding assembly 102 can grasp a new initial filter core from the preparation area and prepare to send it to the strip pasting position.

[0045] The first feeding assembly 101 and the second feeding assembly 102 are slidingly connected with the feeding platform 103 along the first direction X, which means that they can move linearly along the feeding platform 103. This sliding connection can be realized by the cooperation of linear bearings and guide rails, or by the cooperation of sliding blocks and grooves on the platform.

[0046] In summary, by introducing the double feeding assembly (the first feeding assembly 101 and the second feeding assembly 102) and making it work alternately, the problem of low efficiency caused by a single feeding assembly is effectively solved. When one initial filter cartridge is performing the edge strip fitting operation at the edge strip fitting position, the other feeding assembly can simultaneously prepare or transfer the next initial filter cartridge, thereby avoiding idle waiting time of the device. Specifically, while the first feeding assembly 101 transfers the filter cartridge to the designated position after completing the edge strip fitting, the second feeding assembly 102 can immediately transfer the new initial filter cartridge to the edge strip fitting position, realizing continuous feeding and edge strip fitting of the filter cartridge, and greatly improving the production efficiency and the overall operation cycle of the device.

[0047] In some embodiments of the present application, the first feeding mechanism further includes a feeding platform 103 extending along the first direction X; the first feeding assembly 101 and the second feeding assembly 102 are respectively slidingly connected with the feeding platform 103 along the first direction X.

[0048] Please refer to Figure 4 In some embodiments of the present application, the feeding platform 103 includes a feeding guide 1031 and a residue receiving member 1032. The feeding guide is located on one side of the impurity receiving member, and the first feeding assembly 101 and the second feeding assembly 102 are respectively slidingly connected with the feeding guide along the first direction X. The residue receiving member is used to receive the falling impurities.

[0049] The feeding platform 103 is a structure that provides support and movement trajectory for the first feeding assembly 101 and the second feeding assembly 102. It extends along the first direction X, indicating that its main movement direction is linear. The feeding platform 103 can be a solid metal frame with integrated linear guide rails, or a base plate with a precisely machined surface.

[0050] The feeding guide is part of the feeding platform 103, used to accurately guide the sliding movement of the first feeding assembly 101 and the second feeding assembly 102, ensuring their positioning accuracy and movement stability. The feeding guide can be a protruding guide strip on the surface of the feeding platform 103, or a precision guide rail embedded in the interior of the feeding platform 103.

[0051] The residue receiving member is used to collect impurities or debris that may be generated during the loading and transferring of the filter element, so as to maintain the cleanliness of the working environment and prevent the impurities from affecting the normal operation of the equipment. The residue receiving member can be a collection tray or a collection groove extending along the first direction X on one side of the loading guide.

[0052] The provision of the loading platform 103 provides a stable movement basis and accurate guidance for the double loading assembly, and the cooperation of the loading guide ensures the accuracy of the filter element transfer. The introduction of the residue receiving member effectively collects the impurities that may be generated, maintains the cleanliness and operation reliability of the equipment, and further ensures the continuous and efficient production process.

[0053] Please refer to Figure 3 and Figure 4 In some embodiments of the present application, the first loading assembly 101 and / or the second loading assembly 102 each includes a sliding support 10, a carrying assembly 11, and a first filter element driving member 12; the sliding support 10 is slidingly connected to the loading platform 103; the carrying assembly 11 is used to carry the initial filter element and is connected to the end of the sliding support 10 away from the loading platform 103; the first filter element driving member 12 is connected to the sliding support 10; wherein the first filter element driving member 12 is used to drive the sliding support 10 to slide between the specified position and the transition position.

[0054] The sliding support 10 is a component for connecting and supporting the carrying assembly 11 and allowing it to move along the first direction X on the loading platform 103. The sliding support 10 can be slidingly connected to the loading platform 103, for example, through a linear guide rail and a sliding block mechanism, wherein the sliding support 10 is installed with a sliding block and the loading platform 103 is provided with a linear guide rail matched therewith; or the sliding support 10 can also be slidingly connected to the loading platform 103 through a V-shaped groove and a V-shaped wheel mechanism, wherein the sliding support 10 is installed with a V-shaped wheel and the loading platform 103 is provided with a V-shaped groove. The carrying assembly 11 is a component that directly contacts and fixes the initial filter element, which is connected to the end of the sliding support 10 away from the loading platform 103, so as to ensure the stability of the initial filter element during the transfer process. The carrying assembly 11 can be a tray with a groove or a clamping mechanism, which is connected to the upper end of the sliding support 10 through bolts or welding; or the carrying assembly 11 can also be a platform with vacuum suction cups, which is connected to the sliding support 10 through a support. The first filter element driving member 12 is a device that provides power to the sliding support 10 to make it slide along the first direction X between the specified position and the transition position. The first filter element driving member 12 can be, for example, a stepper motor or a servo motor, which drives the sliding support 10 to slide through a synchronous belt or a gear rack mechanism; or it can also be a gas cylinder or a hydraulic cylinder, which drives the sliding support 10 to slide through a connecting rod mechanism.

[0055] In summary, the sliding support 10 is slidingly connected to the loading platform 103, so that the sliding support 10 can move horizontally on the platform accurately, facilitating the adjustment of the initial position of the filter core. The bearing assembly 11 is connected to the end of the sliding support 10 away from the loading platform 103, for stabilizing the bearing initial filter core, ensuring that the filter core does not deviate during the transfer process. The first filter core driving member 12 drives the sliding support 10 to slide between the specified position and the transition position, realizing the accurate movement of the initial filter core from the starting point to the intermediate position, avoiding positioning errors caused by manual operation or single driving mode.

[0056] Please refer to Figures 3-7 In some embodiments of the present application, the first loading assembly 101 and / or the second loading assembly 102 further comprises a second filter core driving member 13 connected with the bearing assembly 11; wherein the second filter core driving member 13 is used to drive the bearing assembly 11 to slide in the second direction Z, so as to transfer the initial filter core from the transition position to the edge strip fitting position, and the second direction Z intersects with the first direction X.

[0057] The second filter core driving member 13 is a device that provides power to the bearing assembly 11 to move in the second direction Z (intersecting with the first direction X), so as to transfer the initial filter core from the transition position to the edge strip fitting position. The second filter core driving member 13 can be, for example, a stepper motor or a servo motor, which drives the bearing assembly 11 to slide through a ball screw or a gear rack mechanism; or it can also be a pneumatic cylinder or a hydraulic cylinder, which drives the bearing assembly 11 to slide through a guide mechanism.

[0058] In summary, the present application effectively solves the problem of inaccurate position during the transfer of the filter core by introducing a multi-stage driving and sliding mechanism, thereby significantly improving the edge strip fitting precision. On the basis of the first filter core assembly, the second filter core driving member 13 drives the bearing assembly 11 to slide in the second direction Z intersecting with the first direction X, so as to accurately transfer the initial filter core from the transition position to the edge strip fitting position. This orthogonal transfer mechanism effectively avoids the cumulative error problem that may be caused by single direction movement, ensuring the accurate alignment of the initial filter core at the edge strip fitting position. Overall, this hierarchical and multi-directional precise driving and positioning mechanism ensures that the initial filter core maintains high-precision positioning throughout the transfer process, providing a solid foundation for subsequent edge strip fitting, thereby significantly improving the overall precision and efficiency of the filter core edge strip fitting.

[0059] Please refer to Figures 3-7In some embodiments of the present application, the bearing assembly 11 comprises a bearing disc 111, a bearing connecting piece 112, and a bearing guide 113 fixedly connected with the sliding support 10 and extending along the second direction Z, the bearing connecting piece 112 being fixedly connected with the bearing disc 111 and being in sliding connection with the bearing guide 113; wherein the second filter element driving member 13 is configured to drive the bearing connecting piece 112 to slide along the second direction Z relative to the bearing guide 113.

[0060] The bearing disc 111 is the core component of the bearing assembly 11, and its main function is to directly bear the initial filter element to be pasted. The bearing disc 111 can be implemented in various ways, for example, it can be a circular or square tray with a flat surface for placing the filter element; or it can be a disc body with specific grooves or positioning structures to ensure stable placement and accurate alignment of the filter element on the bearing disc 111. In this embodiment, the bearing disc 111 is a disc body with specific grooves or positioning structures, and a plurality of spaced positioning fins form a plurality of grooves, each V-shaped part of the folded initial filter element is accommodated in the corresponding groove. The bearing connecting piece 112 is an intermediate structure connecting the bearing disc 111 and the bearing guide 113. Its function is to transmit the driving force of the second filter element driving piece 13 to the bearing disc 111, and to ensure the stable sliding of the bearing disc 111 on the bearing guide 113. The bearing connecting piece 112 can be designed to be integrally formed with the bearing disc 111, or fixedly connected by bolts, welding, etc. In implementation, it can be a block body with sliding fit structure, such as a sliding block or a roller, cooperating with the bearing guide 113; or a U-shaped or C-shaped structure, covering or clamping the bearing guide 113 to achieve sliding connection. The bearing guide 113 is a structure that provides a sliding path for the bearing connecting piece 112, which is fixedly connected with the sliding support 10 and extends along the second direction Z. Its main function is to provide accurate guidance and support for the movement of the bearing disc 111, preventing it from shaking or deviating from the preset path during movement. The bearing guide 113 can adopt the form of a linear guide, such as a dovetail groove guide, a linear bearing guide or a ball screw guide, to provide high-precision linear motion; or it can be a rod or profile with a specific cross-sectional shape, such as a rectangular rod or a T-shaped groove, cooperating with the corresponding structure on the bearing connecting piece 112 to form a sliding pair. In addition, the second filter element driving piece 13 is used to drive the bearing connecting piece 112 to slide relative to the bearing guide 113 along the second direction Z, and the driving mode aims to realize the accurate displacement of the bearing disc 111 under the constraint of the bearing guide 113. The second filter element driving piece 13 can adopt various forms, for example, it can be a linear motor that directly drives the bearing connecting piece 112 to move along the second direction Z; or it can be a gas cylinder or a hydraulic cylinder that drives the bearing connecting piece 112 to slide through the extension and retraction of the piston rod; or it can be a stepper motor or a servo motor cooperating with a screw nut mechanism or a gear rack mechanism to convert rotary motion into linear motion, thereby driving the bearing connecting piece 112 to accurately slide along the second direction Z on the bearing guide 113.

[0061] In summary, the structure of the bearing assembly 11 is optimized, effectively solving the problem of initial filter core shaking and position deviation during transfer. Specifically, the bearing guide 113 is fixedly connected with the sliding support 10 and extends along the second direction Z, forming a solid and precise sliding track, providing stable support and guidance for the bearing connecting piece 112. The bearing connecting piece 112 is fixedly connected with the bearing disc 111 and slidably connected with the bearing guide 113, ensuring that the bearing disc 111 can move smoothly and accurately along the preset second direction Z under the drive of the second filter core driving piece 13. This structure design ensures that the initial filter core maintains accurate positioning during the transfer from the transition position to the edge strip fitting position, avoiding the decline in fitting accuracy due to shaking or deviation. Therefore, this scheme can significantly improve the accuracy of filter core transfer, thereby ensuring the quality and efficiency of subsequent edge strip fitting.

[0062] Please refer to Figures 3-7 In some embodiments of the present application, the bearing assembly 11 further comprises a third filter core driving piece 114 and an identification piece 118 sleeved on the third filter core driving piece 114. The third filter core driving piece 114 is connected with the bearing disc 111, and the identification piece 118 is located between the third filter core driving piece 114 and the bearing disc 111. The third filter core driving piece 114 is used to drive the bearing disc 111 to rotate, so as to fit the edge strip to different sides or different positions of the initial filter core.

[0063] The third filter core driving piece 114 is used to provide rotary power to drive the bearing disc 111 to rotate. It can be implemented in various forms, for example, it can be a stepper motor or a servo motor connected with the bearing disc 111 through gears, belts or direct drive to achieve precise angle control; it can also be a pneumatic or hydraulic rotary actuator driven by controlling air pressure or hydraulic pressure to rotate the bearing disc 111. The third filter core driving piece 114 is provided to enable the initial filter core to be positioned at multiple angles on the bearing disc 111, thereby providing flexibility for subsequent edge strip fitting operations.

[0064] In summary, the present application introduces a rotation control mechanism in the bearing assembly 11, effectively solving the problem of low fitting accuracy of the initial filter core due to lack of accurate rotation positioning during fitting. Specifically, the third filter core driving piece 114 is connected with the bearing disc 111 and can accurately drive the bearing disc 111 to rotate, so that different sides or different positions of the initial filter core can be accurately aligned with the edge strip fitting position.

[0065] Please refer to Figures 3-7In some embodiments of the present application, the recognition member 118 has a rotating mark 115; the bearing assembly 11 further comprises a mark sensor 116, which is located on one side of the bearing disc 111 and is used to detect the rotating mark 115; when the mark sensor 116 detects the rotating mark 115, the side to be attached of the initial filter element on the bearing disc 111 is in a preset position.

[0066] In the present embodiment, the initial filter element has a quadrilateral structure, and when the mark sensor 116 detects the rotating mark 115, the side to be attached of the initial filter element is a long side, and the long side extends along the first direction X.

[0067] The rotating mark 115 is one or more detectable marks provided on the recognition member 118, which provides the rotating position information of the bearing disc 111. The rotating mark 115 can be a physical structure such as a groove, a protrusion, a hole; it can also be an optical mark such as a bar code, a two-dimensional code or a specific pattern; it can also be a magnetic mark such as embedded magnetic material. These rotating marks 115 enable the external detection device to identify the current rotating state or specific angular position of the bearing disc 111. The mark sensor 116 is used to detect the rotating mark 115 on the recognition member 118 and feed back the detected information to the control system. The type of mark sensor 116 can be selected according to the type of rotating mark 115, for example, when the rotating mark 115 is a physical structure, a photoelectric sensor, a proximity sensor or a mechanical limit switch can be used; when the rotating mark 115 is an optical mark, a vision sensor or a bar code reader can be used; when the rotating mark 115 is a magnetic mark, a Hall effect sensor can be used. The function of the sensor is to ensure that the bearing disc 111 can be accurately rotated to a preset position, thereby ensuring the accurate alignment of the initial filter element.

[0068] When the sensor detects the rotating mark 115, the side to be attached of the initial filter element on the bearing disc 111 is in a preset position (for example: the long side of the initial filter element on the bearing disc 111 extends along the first direction X). This technical feature describes the specific state when the rotating mark 115 is detected. This means that when the mark sensor 116 recognizes the preset rotating mark 115, the control system can determine that the initial filter element on the bearing disc 111 has been rotated to a position where its long side is aligned with the first direction X (i.e. the direction in which the filter element feeding mechanism 100 transfers the initial filter element). This alignment state is crucial for the subsequent edge strip attachment operation, as it ensures that the edge strip can be accurately attached along a specific long side of the filter element, avoiding attachment deviation due to incorrect filter element direction.

[0069] In summary, the rotation mark 115 provided on the bearing disc 111 enables the rotational position of the bearing disc 111 to be accurately identified. When the rotation mark 115 is detected by the mark sensor 116, it can be ensured that the long side of the initial filter element extends along the first direction X, thereby ensuring the consistency of the direction and the accuracy of the position of the filter element when the side strip is attached.

[0070] In some embodiments of the present application, the rotation mark 115 is an avoidance opening, the number of avoidance openings is 2, and the avoidance openings are provided on the edge of the bearing disc 111; the two avoidance openings are oppositely arranged in the radial direction of the bearing disc 111; and / or the mark sensor 116 has an avoidance groove 117 for avoiding other positions of the bearing disc 111 except the avoidance openings.

[0071] Specifically, the rotation mark 115 is an avoidance opening, the number of avoidance openings is 2, and the avoidance openings are provided on the edge of the bearing disc 111; the two avoidance openings are oppositely arranged in the radial direction of the bearing disc 111. The avoidance opening is a specific form of the rotation mark 115, which is characterized by forming an opening on the edge of the bearing disc 111 in a physical manner. By providing two avoidance openings and oppositely arranging them in the radial direction of the bearing disc 111, symmetrical detection points can be provided, thereby improving the accuracy and reliability of the rotational position detection. For example, when one of the openings is detected by the mark sensor 116, an initial position can be determined; when the other opposite opening is detected, the position can be further confirmed or calibrated, or used for detecting 180-degree rotation. In this embodiment, when the other opposite opening is detected, it is mainly used for detecting 180-degree rotation, which corresponds to the initial filter element being a quadrilateral filter element including two long sides and two short sides in this embodiment. This design helps to reduce detection errors and simplifies the position calibration process.

[0072] Meanwhile, the mark sensor 116 has an avoidance groove 117 for avoiding other positions of the bearing disc 111 except the avoidance openings. The avoidance groove 117 on the mark sensor 116 is a design matched with the avoidance openings on the bearing disc 111. The function of the avoidance groove 117 is to ensure that the mark sensor 116 can only effectively detect a signal at the avoidance openings, and will not be falsely triggered by other non-opening parts of the bearing disc 111. For example, when the mark sensor 116 is an optical sensor, the avoidance groove 117 can guide the light beam or receive the light, so that a signal is only generated when the avoidance opening passes; when the mark sensor 116 is a mechanical sensor, the avoidance groove 117 can provide an avoidance space for the detection part of the mark sensor 116, so that it can only be contacted or entered at the avoidance opening. This design effectively avoids false detection, improves the detection accuracy of the mark sensor 116, and improves the stability of the system.

[0073] Specifically, the rotation identifier 115 provided on the bearing disc 111, especially adopting two radially opposite avoidance openings, cooperates with the identifier sensor 116 to detect, so that the rotation position of the bearing disc 111 can be accurately identified. When the identifier sensor 116 detects the rotation identifier 115, it can be ensured that the long side of the initial filter element extends along the first direction X, thereby ensuring the consistency of the direction and the accuracy of the position of the filter element when the edge strip is attached. In addition, the groove provided on the identifier sensor 116 is used to avoid the non-avoidance opening part of the bearing disc 111, which further improves the reliability of detection and avoids false triggering.

[0074] In summary, such an integrated rotation driving and accurate position detection scheme enables the initial filter element to be accurately rotated and positioned as needed after being transferred to the edge strip fitting position, greatly improving the precision and automation level of the edge strip attachment, reducing the need for manual intervention and adjustment, and thereby improving the production efficiency and product quality of the entire filter element strip fitting device 1000.

[0075] Please refer to Figures 8-9 In some embodiments of the present application, the filter element correction mechanism 200 includes a correction support 20, a pre-press driving member 21, a pre-press assembly 22, and a side edge correction assembly 23. The correction support 20 is located near the edge strip fitting position. The pre-press driving member 21 is connected to the correction support 20. The pre-press assembly 22 is connected to the pre-press driving member 21 and is used to pre-press the initial filter element located at the edge strip fitting position in the second direction Z under the action of the pre-press driving member 21. The side edge correction assembly 23 is connected to the correction support 20 and is used to correct the position of the pre-pressed initial filter element.

[0076] Please refer to Figures 8-9 In some embodiments of the present application, the filter element correction mechanism 200 further includes a pre-press connecting member 24, which is connected to the pre-press driving member 21 and the pre-press assembly 22. The pre-press driving member 21 drives the pre-press connecting member 24 to move in the second direction Z to drive the pre-press assembly 22 to pre-press the initial filter element.

[0077] The correction support 20 is located near the edge strip fitting position and serves as the structural basis of the entire filter element correction mechanism 200, which is used to bear and fix various components of the correction mechanism, thereby providing stable support and ensuring accurate operation of the correction mechanism. For example, the correction support 20 can be a solid metal frame fixed on the equipment body by bolts or welding; or it can also be an integrally formed structure of high-strength engineering plastic connected to the equipment body by buckles or guide rails.

[0078] The pre-pressing driving member 21 is connected with the correcting support 20, and is used to provide power to realize the pre-pressing action, drive the pre-pressing assembly 22 to pre-press the initial filter element, and stabilize the position of the filter element. Specifically, the pre-pressing driving member 21 can be a pneumatic cylinder, which is driven by compressed air to drive the piston rod to extend or retract, so as to drive the pre-pressing action; or the pre-pressing driving member 21 can also be an electric push rod, which is driven by a motor to realize linear motion through a screw nut mechanism, and provide a pushing force.

[0079] The pre-pressing assembly 22 is connected with the pre-pressing driving member 21, and is pre-pressed in the second direction Z under the action of the pre-pressing driving member 21. The pre-pressing assembly 22 is a component which directly contacts and pre-presses the initial filter element, and the purpose is to stabilize the filter element before correction, and solve the problem that the filter element is easy to deviate or shake during correction. For example, the pre-pressing assembly 22 can be one or more pressing plates, and the surface of the pressing plate can be covered with an elastic material such as rubber or silicone, so as to avoid damaging the surface of the filter element; or the pre-pressing assembly 22 can also be a group of rollers, which are driven by the pre-pressing driving member 21 to move towards the filter element and apply pressure.

[0080] The side edge correcting assembly 23 is connected with the fixing rod of the correcting support 20, and is used to correct the position of the pre-pressed initial filter element. The side edge correcting assembly 23 further adjusts the position of the filter element after the filter element is pre-pressed and stabilized, and ensures the accuracy of the strip. For example, the side edge correcting assembly 23 can be a pair of adjustable clamping blocks, which realize accurate relative movement through a guide rail and a driving mechanism, so as to clamp and correct the side edge of the filter element; or the side edge correcting assembly 23 can also be a group of guide blocks with inclined surfaces, which guide the filter element to be automatically centered when the filter element is pushed in.

[0081] In addition, the filter element correcting mechanism 200 further includes a pre-pressing connecting member 24, which is connected with the pre-pressing driving member 21 and the pre-pressing assembly 22. The pre-pressing connecting member 24 is a mechanical structure for connecting the pre-pressing driving member 21 and the pre-pressing assembly 22, and is used to transmit the movement and force of the pre-pressing driving member 21, and convert the action of the driving member into the pre-pressing action of the pre-pressing assembly 22 on the filter element. For example, the pre-pressing connecting member 24 can be a connecting rod or a push rod, one end of which is connected with the output end of the pre-pressing driving member 21, and the other end of which is connected with the pre-pressing assembly 22; or the pre-pressing connecting member 24 can also be a sliding block mechanism, which is driven by the pre-pressing driving member 21 to move linearly. The pre-pressing driving member 21 drives the pre-pressing connecting member 24 to move in the second direction Z, so as to drive the pre-pressing assembly 22 to pre-press the initial filter element.

[0082] By the above technical solution, before the position correction of the initial filter element, the pre-pressing driving element 21 drives the pre-pressing connecting element 24 to drive the pre-pressing assembly 22 to pre-press the initial filter element located at the edge strip fitting position. This pre-pressing operation can effectively fix the initial filter element at the edge strip fitting position, eliminate the possible shaking or deviation thereof, and thus provide a stable basis for the subsequent accurate position correction. After the initial filter element is stably pre-pressed, the side edge correction assembly 23 corrects the position of the initial filter element accurately. This cooperative working mode of pre-pressing and then correcting significantly improves the accuracy and stability of the position correction of the filter element, and effectively avoids the problem of reduced edge strip fitting accuracy caused by the deviation of the filter element during the correction. Especially after the filter element loading mechanism 100 transfers the initial filter element to the edge strip fitting position, the pre-pressing step can quickly stabilize the filter element, ensure that the subsequent edge strip fitting operation can be performed in an accurately aligned state, and thus ensure the quality and consistency of the edge strip fitting of the final filter element product.

[0083] Please refer to Figures 8-9 In some embodiments of the present application, the side edge correction assembly 23 includes two groups of side edge correction elements 231, which are oppositely arranged along the first direction X; each group of side edge correction elements 231 includes at least one sub-correction element, and the sub-correction elements of the two groups of side edge correction elements 231 are used to contact the clamped edge of the initial filter element to correct the position of the initial filter element.

[0084] Among them, the above-mentioned side edge correction assembly 23 includes two groups of side edge correction elements 231, which are oppositely arranged along the first direction X, which means that the two groups of correction elements are respectively located on both sides of the initial filter element and can exert force on the filter element from opposite directions. For example, the first direction X can be the length direction of the filter element, and the two groups of correction elements are respectively located on both sides of the long side of the filter element. This opposite arrangement can ensure that the initial filter element is clamped or pushed from both sides, thereby achieving accurate centering of the filter element. Specifically, the two groups of side edge correction elements 231 can be composed of independent mechanical arms or clamps driven by air cylinders, and respectively move from both sides to the center of the filter element; or they can be composed of a guide block fixed on the correction support 20 and another movable guide block, and the relative movement of the two guide blocks is realized through a driving mechanism to clamp the filter element.

[0085] Each group of side edge correction elements 231 is further subdivided into at least one sub-correction element. These sub-correction elements are the basic units that directly contact the clamped edge of the initial filter element and perform the actual correction action. The design of at least one sub-correction element allows flexible configuration according to the length of the filter element and the correction requirement, to ensure effective transmission of the correction force. For example, the sub-correction element can be a block with a flat contact surface, which is driven by a cylinder or a servo motor to move linearly and contact the side edge of the filter element; or it can be a roller with an arc-shaped or V-shaped groove, which provides guiding and correction when contacting the filter element, while reducing friction.

[0086] Referring to Figures 8-9 In some embodiments of the present application, each group of side edge correction members 231 includes a first sub-correction member 2311, a second sub-correction member 2312, and a third sub-correction member 2313. The third sub-correction member 2313 is arranged between the first sub-correction member 2311 and the second sub-correction member 2312, and is used to correct the position of the initial filter element at different positions of the initial filter element.

[0087] In order to achieve more precise and comprehensive correction, each group of side edge correction members 231 specifically includes a first sub-correction member 2311, a second sub-correction member 2312, and a third sub-correction member 2313. The third sub-correction member 2313 is arranged between the first sub-correction member 2311 and the second sub-correction member 2312. This arrangement allows the sub-correction members to act on different positions of the initial filter element, such as the two ends and the middle of the filter element. This multi-point correction method can effectively avoid the filter element warping or uneven stress caused by single-point correction, thereby improving the stability and accuracy of the correction. These sub-correction members can be independently driven, or synchronized or sequentially actuated through a linkage mechanism to accommodate filter elements of different lengths and shapes. They can also be installed on the same guide rail and positioned and driven by spacer blocks or independent drive units.

[0088] Referring to Figures 8-9 In some embodiments of the present application, the filter element correction mechanism 200 further includes a first correction connecting member 25 that is slidingly connected to the correction bracket 20. The first sub-correction member 2311 and the second sub-correction member 2312 are respectively slidingly connected to the first correction connecting member 25 to adjust the distance between the first sub-correction member 2311, the second sub-correction member 2312, and the third sub-correction member 2313, so as to adapt to different sizes of initial filter elements.

[0089] The filter core correction mechanism 200 further comprises a first correction connecting member 25 fixedly connected to the correction support 20 to provide stable support and guidance for the sub-correction members. The first sub-correction member 2311 and the second sub-correction member 2312 are respectively in sliding connection with the first correction connecting member 25, which means that their positions can be adjusted along the first correction connecting member 25. By adjusting the distance between the first sub-correction member 2311, the second sub-correction member 2312 and the third sub-correction member 2313, the filter core correction mechanism 200 can flexibly adapt to filter cores of different sizes, thereby enhancing the versatility and application range of the device. For example, the first correction connecting member 25 can be one or more guide rails, and the first sub-correction member 2311 and the second sub-correction member 2312 are in sliding connection with the guide rails through sliders or rollers and are fixed or adjusted in position through locking mechanisms or driving mechanisms; or it can be a profile with a T-shaped slot or a dovetail slot, and the base of the sub-correction member is in sliding connection with the first correction connecting member 25 through the corresponding structure, and is locked through bolts or pneumatic clamping devices.

[0090] Please refer to Figures 8-10 In some embodiments of the present application, each sub-correction member comprises a second correction connecting member 26 connected with the first correction connecting member 25, a correction block 27 for contacting the clamped edge of the initial filter core to correct the position of the initial filter core, and a pushing member 28 fixedly connected with the second correction connecting member 26 and connected with the correction block 27 for driving the correction block 27 to approach or move away from the initial filter core.

[0091] The internal structure of each sub-correction member (e.g. the first sub-correction member 2311 or the second sub-correction member 2312 or the third sub-correction member 2313) is further refined, including a second correction connecting member 26, a correction block 27 and a pushing member 28. The second correction connecting member 26 is connected with the first correction connecting member 25 as a support structure inside the sub-correction member to provide a mounting platform for the correction block 27 and the pushing member 28. The correction block 27 is the part that directly contacts the clamped edge of the initial filter core and is used to actually perform position correction. The pushing member 28 is fixedly connected with the second correction connecting member 26 and connected with the correction block 27, and its function is to drive the correction block 27 to accurately approach or move away from the initial filter core, thereby achieving precise control of the position of the filter core. For example, the second correction connecting member 26 can be a bracket or a sliding seat fixed on the first correction connecting member 25; the correction block 27 can be made of wear-resistant materials such as polyurethane, rubber or engineering plastics to avoid damaging the surface of the filter core and provide sufficient friction, and its shape can be flat, curved or with a specific profile; the pushing member 28 can be a pneumatic cylinder to drive the correction block 27 to perform linear reciprocating motion, or it can be a lead screw mechanism driven by a stepper motor or a servo motor to provide more precise position control and thrust adjustment.

[0092] By the technical scheme, the two groups of side edge correction members 231 are oppositely arranged along the first direction X, ensuring that the correction force is applied to the filter core from both sides at the same time, realizing uniform clamping and position alignment, and avoiding unilateral deviation affecting overall precision. Each group of side edge correction members 231 includes a plurality of sub-correction members, wherein the first sub-correction member 2311, the second sub-correction member 2312 and the third sub-correction member 2313 are arranged at intervals, allowing independent application of correction force at different positions of the filter core, covering a wider area, and improving the comprehensiveness and accuracy of position correction. The first correction connecting member 25 is fixed to the correction support 20, and the first sub-correction member 2311 and the second sub-correction member 2312 are slidingly connected thereto, facilitating manual or automatic adjustment of the distance between them and the third sub-correction member 2313, thereby adapting to filter cores of different sizes and enhancing the versatility and flexibility of the device. In each sub-correction member, the second correction connecting member 26 provides stable connection support, the correction block 27 directly contacts the clamped edge of the filter core, and the pusher 28 drives the correction block 27 to move accurately, realizing controllable approaching or moving away action, ensuring stable and reliable correction process, and effectively improving the positioning accuracy before the strip is attached. Overall, the scheme significantly improves the accuracy of filter core position correction and the adaptability to filter cores of different sizes through the multi-point, adjustable and accurate driving correction mechanism, thereby providing a reliable positioning basis for the subsequent edge strip attaching process, and effectively solving the problem of unsatisfactory correction effect in the prior art, which affects the strip attaching precision.

[0093] Please refer to Figure 11 In some embodiments of the present application, the pressure maintaining mechanism 300 includes two pressure maintaining plates 30, a pressure maintaining connecting plate 31 and a pressure maintaining driving member 32 oppositely arranged along the pressure maintaining direction. The pressure maintaining plate 30 is used to apply pressure to the attached filter core edge strip, so that the filter core edge strip is attached to the initial filter core. The pressure maintaining connecting plate 31 is slidingly connected to the two pressure maintaining plates 30 respectively, so as to be adjusted according to the size between the two sides of the initial filter core to be attached. The pressure maintaining driving member 32 is connected to the pressure maintaining plate 30 respectively, and is used to drive the pressure maintaining plate 30 to move along the pre-pressing direction or the pressure maintaining direction.

[0094] Two pressure maintaining plates 30 are used to apply pressure to the attached filter core edge strip, so that the filter core edge strip is attached to the initial filter core. The pressure maintaining plate 30 can adopt a flat plate structure with a certain rigidity, such as a metal plate or a high-strength plastic plate, and the surface can be covered with an elastic material such as rubber or silicone to provide uniform pressure distribution and avoid damage to the filter core. The pressure maintaining connecting plate 31 is used to connect the two pressure maintaining plates 30 and allows the two pressure maintaining plates 30 to be respectively connected with the pressure maintaining connecting plate 31 to adjust according to the size between the two sides of the initial filter core to be attached. The pressure maintaining connecting plate 31 can adopt a structure with guide rails and sliding blocks, or a structure with threaded rods and nuts, by rotating the threaded rods to adjust the distance between the pressure maintaining plates 30. The pressure maintaining driving member 32 is connected with the pressure maintaining plate 30 and is used to drive the pressure maintaining plate 30 to move in the pre-pressing direction or the pressure maintaining direction. The pressure maintaining driving member 32 can adopt a pneumatic cylinder or a hydraulic cylinder to drive the pressure maintaining plate 30 by air pressure or hydraulic pressure, or a stepper motor or a servo motor cooperating with a lead screw transmission mechanism to realize accurate position and force control.

[0095] Through the above technical solution, the pressure maintaining driving member 32 can drive the pressure maintaining plate 30 to move accurately in the pressure maintaining direction and apply pressure. At the same time, the pressure maintaining connecting plate 31 allows the pressure maintaining plate 30 to slide and adjust the distance, ensuring that the two pressure maintaining plates 30 can apply uniform and moderate pressure to filter core edge strips of different sizes. This effectively avoids the problem of uneven or insecure attachment caused by size errors, significantly improves the attachment quality and stability of the filter core edge strip, and further improves the overall edge strip attachment efficiency and product qualification rate.

[0096] Please refer to Figure 11 In some embodiments of the present application, the pressure maintaining mechanism 300 further comprises two filter core length sensors 33, which are slidably connected to the pressure maintaining plates 30. The two filter core length sensors 33 are used to detect the positions of the clamped edges of the initial filter core respectively, and calculate the length between the two clamped edges of the initial filter core.

[0097] The pressure maintaining mechanism 300 further comprises two filter core length sensors 33, which are slidably connected to the pressure maintaining plates 30. The two filter core length sensors 33 are used to detect the positions of the clamped edges of the initial filter core respectively, and calculate the length between the two clamped edges of the initial filter core. The filter core length sensor 33 can adopt a laser displacement sensor to measure the distance by emitting a laser beam and receiving the reflected light, or an ultrasonic sensor to measure the distance by emitting and receiving ultrasonic waves, or a vision sensor to detect the filter core edge and calculate the length by image recognition technology. The identification sensor 116 can be installed on the side or inside of the pressure maintaining plate 30 and can be slid relative to the pressure maintaining plate 30 by a sliding rail or the like to adapt to the detection of filter cores of different sizes.

[0098] By the above technical solution, the two filter core length sensors 33 can detect the clamped edge position of the initial filter core in real time and accurately calculate the length thereof, which not only can provide accurate size data for the pressure maintaining operation, but also can verify whether the size of the initial filter core of the batch meets the requirements, and if not, data support can be provided for the production of the initial filter core of the next batch.

[0099] Please refer to Figure 12 In some embodiments of the present application, the filter core edge strip transferring mechanism 400 is located on one side of the filter core correcting mechanism 200 and is used to preliminarily attach the filter core edge strip to the side edge to be attached of the initial filter core.

[0100] The filter core edge strip transferring mechanism 400 is used to preliminarily attach the preliminarily prepared filter core edge strip to the side edge to be attached of the initial filter core, preparing for the subsequent final pressure maintaining attachment. The main function of the filter core edge strip transferring mechanism 400 is to realize the preliminary positioning and fixing of the edge strip, so as to solve the problems of deviation and misplacement of the edge strip before the final attachment, and improve the attachment accuracy and efficiency. Specifically, the filter core edge strip transferring mechanism 400 can include an edge strip feeding unit, an edge strip grabbing unit and an edge strip preliminary attachment unit. The edge strip feeding unit is responsible for feeding out the edge strip, the edge strip grabbing unit (such as a suction cup or a clamp) is used to grab the edge strip, and then the edge strip is gently pressed onto the side edge of the initial filter core by the edge strip preliminary attachment unit (such as a roller or a pressing plate with slight pressure). The whole process is coordinated by the control system to ensure that the edge strip is accurately transferred and preliminarily attached after the filter core is corrected. Alternatively, the filter core edge strip transferring mechanism 400 can also use a mechanical arm cooperating with a vacuum suction cup or an electrostatic adsorption device. The mechanical arm picks up the edge strip from the edge strip warehouse, and then according to the filter core position information provided by the filter core correcting mechanism 200, the edge strip is accurately placed and lightly pressed on the side edge to be attached of the initial filter core. The end effector of the mechanical arm can be integrated with a micro-pressure device to ensure that the edge strip does not damage the surface of the filter core during preliminary attachment.

[0101] By the above technical solution, the filter core edge strip transferring mechanism 400 is located on one side of the filter core correcting mechanism 200, which ensures that after the initial filter core is accurately corrected, the edge strip can be preliminarily attached to the side edge to be attached thereof immediately, avoiding deviation or misplacement of the edge strip during the transferring process due to too long distance, thereby realizing the preliminary accurate positioning of the edge strip.

[0102] Please refer to Figure 12In some embodiments of the present application, the filter core edge strip attaching device 1000 further comprises an edge strip length detection mechanism 500 located on one side of the edge strip transfer mechanism and used for gluing the initial edge strip and cutting the glued edge strip into filter core edge strips with a preset length, so as to ensure that the edge strip has correct length and necessary adhesive before being attached, thereby solving the problems of mismatched length and weak adhesion of the edge strip and ensuring the attachment quality and material utilization rate.

[0103] Through the above technical solution, the edge strip length detection mechanism 500 is located on one side of the edge strip transfer mechanism and can glue the initial edge strip and accurately cut it into filter core edge strips with a preset length. Gluing enhances the adhesion between the edge strip and the filter core, and accurate cutting ensures the perfect match between the edge strip size and the side edge of the filter core, effectively avoiding poor attachment or material waste caused by inaccurate length. The synergistic effect of the edge strip length detection mechanism 500 and the filter core edge strip transfer mechanism 400, or independent use, optimizes the edge strip processing flow, significantly improves the precision and reliability of the filter core edge strip attachment, reduces manual intervention, and thus improves the overall production efficiency and product quality.

[0104] Please refer to Figure 12 In some embodiments of the present application, the filter core edge strip length detection mechanism 500 comprises an edge strip feeding assembly 50, a gluing assembly 51, an edge strip sensor 52, a sensing assembly 53, and a cutter assembly 54; the edge strip feeding assembly 50 is used for feeding the initial edge strip so that the initial edge strip moves along the first direction X; the gluing assembly 51 is located on one side of the edge strip feeding assembly 50 along the first direction X and is used for gluing the initial edge strip; the edge strip sensor 52 is located between the edge strip feeding assembly 50 and the gluing assembly 51 and is arranged close to the gluing assembly 51, and the edge strip sensor 52 is used for sensing whether the initial edge strip moves to a first sensing position; the sensing assembly 53 is located on one side of the gluing assembly 51 away from the edge strip sensor 52 and is used for sensing whether the glued edge strip moves to a second sensing position; the cutter assembly 54 is located between the gluing assembly 51 and the sensing assembly 53 and is used for cutting the glued edge strip when it moves to the second sensing position to obtain a filter core edge strip; wherein the distance between the cutting position corresponding to the cutter of the cutting assembly and the second sensing position along the first direction X is the length of the filter core edge strip.

[0105] The edge strip feeding assembly 50 is used for feeding the initial edge strip so that the initial edge strip moves along the first direction X. The edge strip feeding assembly 50 can adopt a roller feeding mechanism, which clamps the initial edge strip by one or more pairs of driving rollers and driven rollers and drives the rollers to rotate by a motor, thereby feeding the initial edge strip along the first direction X; or it can also adopt a belt conveying mechanism, which conveys the initial edge strip placed on the conveying belt along the first direction X by driving the conveying belt to move.

[0106] The gluing assembly 51 is located on one side of the edge strip feeding assembly 50 along the first direction X and is used for gluing the initial edge strip. The gluing assembly 51 can adopt a glue spraying head to uniformly coat the glue on the surface of the initial edge strip through high-pressure spraying; or, a roller coating mechanism can also be adopted to transfer and coat the glue from the glue tank to the initial edge strip through the contact and rotation of one or more glue rollers.

[0107] The edge strip sensor 52 is located between the feeding assembly and the gluing assembly 51 and is arranged close to the gluing assembly 51, and is used for sensing whether the initial edge strip moves to the first sensing position. The edge strip sensor 52 can adopt a photoelectric sensor to detect whether the initial edge strip blocks the light path through the emission and reception of light beams, so as to judge whether it reaches the first sensing position; or, a proximity sensor can also be adopted to trigger a signal by sensing the proximity of the initial edge strip to indicate its position. The sensing assembly 53 is located on the side of the gluing assembly 51 away from the edge strip sensor 52 and is used for sensing whether the glued edge strip moves to the second sensing position. The sensing assembly 53 can adopt an array of photoelectric sensors to accurately detect whether the edge or specific mark of the glued edge strip reaches the second sensing position through the cooperative work of multiple photoelectric sensors; or, a laser displacement sensor can also be adopted to determine whether the glued edge strip reaches the preset second sensing position by measuring the distance between the glued edge strip and the reference point.

[0108] The cutter assembly 54 is located between the gluing assembly 51 and the sensing assembly 53 and is used for cutting the glued edge strip when it moves to the second sensing position to obtain the filter core edge strip. The distance between the cutting position corresponding to the cutter of the cutting assembly and the second sensing position in the first direction X is the length of the filter core edge strip.

[0109] Through the above technical solution, the filter core edge strip length detection mechanism 500 can accurately control the length of the filter core edge strip. Specifically, the edge strip feeding assembly 50 and the edge strip sensor 52 work cooperatively to ensure that the initial edge strip is accurately fed and positioned before gluing, avoiding the deviation of the gluing position. After the initial edge strip is uniformly glued by the gluing assembly 51, the sensing assembly 53 accurately detects whether the glued edge strip reaches the second sensing position, thereby triggering the cutter assembly 54 to cut. The fixed distance between the cutting position and the second sensing position ensures that the cut filter core edge strip has a preset accurate length. Therefore, the filter core edge strip length detection mechanism 500 of the present application not only improves the cutting accuracy and production efficiency, but also reduces the waste rate.

[0110] Please refer to Figure 13In some embodiments of the present application, the cutter assembly 54 includes a base 541, a cutter 542, a position transfer assembly 543, and an anti-adhesion forming assembly 544. The cutter 542 is arranged on the base 541. The position transfer assembly 543 is connected to the base 541 and the cutter 542. The position transfer assembly 543 is configured to drive the cutter 542 to reciprocate along a direction intersecting the movement direction of the initial edge strip (e.g., the second direction Z). The anti-adhesion forming assembly 544 is connected to the base 541 and arranged on one side of the cutter 542 and the base 541. The anti-adhesion forming assembly 544 is configured to form an anti-adhesion structure on the surface of the cutter 542, which is configured to block the direct contact between the adhesive and the surface of the cutter 542.

[0111] The base 541 is configured to provide stable support, which can be made of high-strength metal plates or profiles welded together to provide sufficient rigidity and stability. Alternatively, the base 541 can be made of a cast part to obtain high precision and high strength through one-piece forming. The cutter 542 is arranged on the base 541, which can be made of high-hardness alloy steel blades formed into sharp edges through precision grinding to achieve efficient cutting. Alternatively, the cutter 542 can be made of ceramic blades with excellent wear resistance and chemical stability. The position transfer assembly 543 is connected to the base 541 and the cutter, which is configured to drive the cutter 542 to reciprocate along the second direction Z. The position transfer assembly 543 can be a linear guide and ball screw cooperating with a stepping motor or a servo motor, which drives the screw to rotate and drives the cutter 542 connected to the guide to move accurately and reciprocally along the second direction Z. Alternatively, the position transfer assembly 543 can be a pneumatic or hydraulic cylinder, which drives the piston rod to extend and retract by controlling the air pressure or hydraulic pressure, thereby driving the cutter 542 to reciprocate along the second direction Z.

[0112] The anti-adhesion forming assembly 544 is connected to the base 541 and arranged on one side of the cutter 542 and the base 541, which is configured to form an anti-adhesion structure on the surface of the cutter 542, which is configured to block the direct contact between the adhesive and the surface of the cutter 542. The anti-adhesion forming assembly 544 can be a spraying device that sprays a low-surface-energy material on the surface of the cutter 542 to form a smooth and non-sticky anti-adhesion structure. Alternatively, the anti-adhesion forming assembly 544 can be a lubricant coating device that periodically coats a layer of anti-adhesion lubricant (such as silicone oil, paraffin, etc.) on the surface of the cutter 542 to form a physical isolation layer. Alternatively, the anti-adhesion forming assembly 544 can be an ultrasonic vibration device that vibrates the cutter at a high frequency to make it difficult for the adhesive to adhere.

[0113] By the above technical solution, the anti-adhesion forming assembly 544 forms an anti-adhesion structure on the surface of the cutter 542, effectively blocking the direct contact between the glue and the surface of the cutter. This fundamentally solves the problem of glue adhesion to the cutter, avoiding the problems of uneven cutting, reduced cutting precision, and frequent downtime for cleaning caused by glue accumulation. Therefore, the filter core edge strip length detection mechanism 500 of the present application not only improves the cutting precision and production efficiency, reduces the waste rate, but also prolongs the service life of the cutter and related components, reduces the maintenance cost, thereby significantly improving the production quality and efficiency of the filter core edge strip.

[0114] The above technical solution will be described in more detail through a more specific example as follows: In a filter core production workshop, it is necessary to accurately attach the filter core edge strip to the initial filter core. The traditional strip attaching equipment often causes inaccurate edge strip attachment due to the lack of accurate correction of the position of the initial filter core, affecting product quality.

[0115] Firstly, the initial filter core enters the working process through the filter core feeding mechanism 100. The filter core feeding mechanism 100 includes a feeding platform 103, on which a first feeding assembly 101 and a second feeding assembly 102 are slidably connected. For example, when the first feeding assembly 101 carries an initial filter core, its sliding support 10 is driven by the first filter core driving member 12 to slide from the feeding position to the transition position along the first direction X. Then, the second filter core driving member 13 in the carrying assembly 11 drives the carrying connecting member 112 to slide relative to the carrying guide member 113 along the second direction Z, accurately transferring the initial filter core from the transition position to the edge strip attachment position. The carrying disc 111 of the carrying assembly 11 is provided with rotating marks 115, such as two radially opposite avoiding openings, and a sensor is located on one side of the carrying disc 111 for detecting these rotating marks 115. When the sensor detects the rotating marks 115, it ensures that the long side of the initial filter core extends along the first direction X, preparing for subsequent strip attachment. After the first feeding assembly 101 completes the transfer, the second feeding assembly 102 can alternately carry another initial filter core and perform similar operations, thereby realizing continuous and efficient edge strip attachment. The feeding platform 103 is also provided with a feeding guide member and a residue receiving member, which is used to collect impurities that may fall during production, keeping the equipment clean.

[0116] When the initial filter cartridge reaches the edge strip fitting position, the filter cartridge rectifying mechanism 200 starts to work, which is a key step to ensure the fitting accuracy. The filter cartridge rectifying mechanism 200 includes a rectifying support 20, near which a pre-pressing driving member 21 and a pre-pressing assembly 22 are arranged. The pre-pressing driving member 21 drives the pre-pressing assembly 22 to move along the second direction Z through a pre-pressing connecting member 24, and slightly pre-presses the initial filter cartridge located in the edge strip fitting position, preliminarily fixing the position thereof. Then, the side edge rectifying assembly 23 is started. The assembly includes two groups of side edge rectifying members 231 oppositely arranged along the first direction X, each group of side edge rectifying members 231 is composed of at least one sub-rectifying member, for example, a first sub-rectifying member 2311, a second sub-rectifying member 2312 and a third sub-rectifying member 2313, wherein the third sub-rectifying member 2313 is arranged at intervals between the first sub-rectifying member 2311 and the second sub-rectifying member 2312. These sub-rectifying members drive the rectifying blocks 27 to contact the clamped edges of the initial filter cartridge through the pushing members 28, and accurately rectify the position of the initial filter cartridge at multiple points. The first sub-rectifying member 2311 and the second sub-rectifying member 2312 are in sliding connection with the first rectifying connecting member 25, and the distance between them and the third sub-rectifying member 2313 can be adjusted to adapt to initial filter cartridges of different sizes. Through this two-stage (pre-pressing and side edge rectifying) fine adjustment, the position of the initial filter cartridge is calibrated to a very high accuracy, effectively solving the problem of low edge strip fitting accuracy caused by inaccurate position of the filter cartridge in the traditional device.

[0117] At the same time or after the filter cartridge rectifying mechanism 200 works, the filter cartridge edge strip transferring mechanism 400 and the edge strip length detecting mechanism 500 work cooperatively. The edge strip length detecting mechanism 500 first feeds the initial edge strip, so that it moves along a preset direction. The glue applying assembly 51 applies glue to the initial edge strip. The edge strip sensor 52 and the sensing assembly 53 respectively detect whether the initial edge strip and the glued edge strip move to a preset sensing position. When the glued edge strip moves to the second sensing position, the cutter of the cutter assembly 54 reciprocates along a direction perpendicular to the moving direction of the initial edge strip under the driving of the position transferring assembly 543, and cuts the glued edge strip into filter cartridge edge strips with a preset length. The cutter assembly 54 is also provided with an anti-adhesion forming assembly 544 for forming an anti-adhesion structure on the surface of the cutter, effectively blocking the direct contact between the glue and the surface of the cutter, and ensuring smooth cutting without residue. The cut filter cartridge edge strips are then pre-fitted to the to-be-fitted side edges of the initial filter cartridge with rectified position by the filter cartridge edge strip transferring mechanism 400.

[0118] Then, the pressure maintaining mechanism 300 applies pressure to the pre-attached filter gasket to ensure that it is firmly attached to the initial filter. The pressure maintaining mechanism 300 includes two pressure maintaining plates 30 arranged opposite to each other along the pressure maintaining direction, which are respectively connected to the pressure maintaining connecting plate 31 to adapt to different sizes of the initial filter. The pressure maintaining drive 32 drives the pressure maintaining plates 30 to move along the pre-pressing direction or the pressure maintaining direction to apply uniform and stable pressure to the filter gasket. In addition, two filter length sensors 33 are connected to the pressure maintaining plates 30 to detect the positions of the clamped edges of the initial filter and calculate the length between the two clamped edges, so as to accurately control the distance and pressure of the pressure maintaining plates 30 and ensure the attachment effect.

[0119] Finally, after the initial filter on the first feeding assembly 101 is completed with the gasket, the second filter drive 13 in the bearing assembly 11 of the first feeding assembly 101 drives the bearing connecting piece 112 to slide in the opposite direction relative to the bearing guide 113, and the sliding support 10 of the first feeding assembly 101 is driven by the first filter drive 12 to return to the feeding position from the transition position in the opposite direction to provide feeding space for the initial filter carried by the second feeding assembly 102; at the same time, the initial filter of the second feeding assembly 102 enters the gasket attachment position to perform a new round of gasket attachment.

[0120] Through the above-mentioned cooperative work, the filter gasket attaching device 1000 overcomes the problem of insufficient position correction of the filter in the prior art. The introduction of the filter correction mechanism 200, especially its pre-pressing and multi-point side edge correction function, ensures the accurate alignment of the initial filter before gasket attachment. Compared with the traditional device lacking such a correction mechanism, the gasket attachment precision of the filter and the product quality are significantly improved, the waste rate is reduced, and the production efficiency is improved.
