[0074] Understandably, in order to facilitate the sleeve of the sealing ring into the periphery of the inner shell, the clamp fingers 20141 need to sleeve the sealing ring and stretch it outward so that the diameter of the annular ring of the sealing ring is greater than the diameter of the circular body of the inner shell. The give-way slot provided on the push ring 20142 allows the clamp fingers 20141 to move in the give-way slot, so as to facilitate the sleeve of the sealing ring by the clamp fingers 20141 after stretching and the push of the sealing ring from the clamp fingers 20141 to the sleeve sealing ring position on the inner shell by the push ring 20142; wherein the number of give-way slots can be consistent with the number of clamp fingers 20141.

[0075] For the clamp fingers 20141, the clamp fingers 20141 can be driven to open and close by a gas cylinder, the distal end of the clamp fingers 20141 can be provided with an inclined surface to facilitate the smooth sliding of the sealing ring to the sleeve sealing ring position on the inner shell during the push of the sealing ring by the push ring 20142, and the number of the clamp fingers 20141 can be four.

[0076] For the lifting driving mechanism, the lifting driving mechanism can be a gas cylinder driving slide rod structure, and the push ring 20142 is driven to move up and down by the lifting driving mechanism, so as to facilitate the push of the sealing ring on the clamp fingers 20141 to the sleeve sealing ring position on the inner shell.

[0077] In addition, the first sealing ring clamp jaw 2014 is arranged at the moving end of the lifting driving mechanism, and the lifting driving mechanism is arranged at the moving end of the moving driving mechanism.

[0078] For the lifting driving mechanism, the lifting driving mechanism can be a cylinder driving moving pair structure, through which the first sealing ring clamp jaw 2014 can be driven to approach or move away from the positioning hole or the limiting block of the first sealing ring discharge channel 2013, so as to facilitate the sealing ring to be sleeved into the sleeve sealing ring position of the inner shell on the positioning hole after being grabbed from the limiting block.

[0079] For the moving driving mechanism, the moving driving mechanism can be a cylinder driving moving pair structure, through which the first sealing ring clamp jaw 2014 can be driven to move between the discharge port of the first sealing ring discharge channel 2013 and the positioning hole, so as to facilitate the sealing ring to be sleeved into the sleeve sealing ring position of the inner shell on the positioning hole after being grabbed from the limiting block.

[0080] For the positional relationship of the inner shell discharge channel 2011, the first sealing ring discharge channel 2013 and the positioning frame 2015, the inner shell discharge channel 2011 and the first sealing ring discharge channel 2013 are perpendicular to each other, and the positioning frame 2015 is arranged at the vertical angle of the inner shell discharge channel 2011 and the first sealing ring discharge channel 2013.

[0081] It can be understood that, by arranging the positioning frame 2015 at the vertical angle of the inner shell discharge channel 2011 and the first sealing ring discharge channel 2013, the distance between the positioning frame 2015 and the discharge ports of the inner shell discharge channel 2011 and the first sealing ring discharge channel 2013 is greatly shortened, so as to improve the installation efficiency of the sealing ring.

[0082] For the feeding mode of the inner shell, the inner shell feeding can be a lifting machine cooperating with a conveying straight vibration, through which the inner shell can be moved to the inner shell discharge channel 2011, and the inner shell can be moved to the discharge port through the vibration of the inner shell discharge channel 2011, so as to be grabbed by the inner shell feeding jaw 2012.

[0083] For the first rotating platform 2024, the first rotating platform 2024 has a placement plate 20241 and a rotating driving mechanism 20242 connected to the placement plate 20241 to drive the placement plate 20241 to rotate an angle.

[0084] For the placement plate 20241, the placement plate 20241 can be arranged as a circular plate with a diameter greater than the diameter of the outer shell, through which the outer shell on the placement plate 20241 can be rotated to the correct angle in cooperation with the rotating driving mechanism 20242, so as to be placed into the tooling 101 in the correct posture after being grabbed by the outer shell feeding jaw 2025.

[0085] For the rotating driving mechanism 20242, the rotating driving mechanism 20242 can be a motor-driven synchronous belt transmission structure. The rotating driving mechanism 20242 can drive the placing plate 20241 to rotate, so as to rotate the shell on the placing plate 20241 to the correct angle, and facilitate the shell to be placed into the tooling 101 in the correct posture after being grabbed by the shell feeding claw 2025.

[0086] The first rotating platform 2024 is provided with a second vision module 2026 above the first rotating platform 2024. The second vision module 2026 is adapted to identify the angle of the shell on the first rotating platform 2024.

[0087] It can be understood that the angle of the shell on the first rotating platform 2024 can be detected by the second vision module 2026, and the rotating driving mechanism 20242 is controlled to drive the placing plate 20241 to rotate to the correct angle, so as to facilitate the shell to be placed into the tooling 101 in the correct posture after being grabbed by the shell feeding claw 2025.

[0088] The first vision module 2023 and the second vision module 2026 can be cameras, and the cameras work with the PLC on the equipment.

[0089] For the shell feeding claw 2025 and the inner shell feeding claw 2012, the shell feeding claw 2025 and the inner shell feeding claw 2012 each include an air clamp, a lifting driving mechanism, a moving driving mechanism, and a lifting driving piece.

[0090] Specifically, the air clamp is arranged on the moving end of the lifting driving mechanism, the lifting driving mechanism is arranged on the moving end of the moving driving mechanism, and the moving driving mechanism is arranged on the moving end of the lifting driving piece.

[0091] The shell feeding claw 2025 and the inner shell feeding claw 2012 have the same structure and working principle. The shell feeding claw 2025 is described below:

[0092] For the air clamp, the air clamp is matched with the lifting driving mechanism, the moving driving mechanism and the lifting driving member of the loading claw 2025 on the shell to grab the shell on the placing plate 20241 and then move it to the tool 101; wherein the air clamp can be a clamp jaw air cylinder matched with a clamp jaw structure, and the clamp jaw can be arranged in an arc shape to match the shell contour, so as to firmly grab the shell. For the lifting driving mechanism, the lifting driving mechanism can be a cylinder structure, which can drive the air clamp to move up and down, and cooperate with the moving driving mechanism and the lifting driving member to move the shell on the placing plate 20241 to the tool 101. For the moving driving mechanism, the moving driving mechanism can be a cylinder structure, which can drive the lifting driving mechanism and the air clamp to move up and down, and cooperate with the lifting driving member to move the shell on the placing plate 20241 to the tool 101. For the lifting driving member, the lifting driving member can be a motor-driven sliding module structure, which drives the air clamp to move up and down, the lifting driving mechanism and the moving driving mechanism to move up and down as a whole, so as to move the shell on the placing plate 20241 to the tool 101 after grabbing.

[0093] In the conveying line 10, for the tool 101, the tool 101 is arranged at intervals on the conveying belt of the conveying line 10, and the tool 101 can be arranged in a circular ring structure with a positioning groove, so that the shell can be fixed and the posture of the shell can be limited by the tool 101, so as to facilitate the subsequent placement of the inner shell.

[0094] In combination Figures 8-10 For the filter element body assembly device 30, the loading assembly 302 has a skeleton loading claw 3021 and a rotating claw 3022, the rotating claw 3022 is suitable for turning the skeleton loaded with scale inhibitor by 180°, and the skeleton loading claw 3021 is suitable for clamping the turned skeleton from the rotating claw 3022 and loading the skeleton into the inner shell of the first to-be-assembled part on the tool 101; the second assembly component 303 includes a positioning claw 3031 and a pressing mechanism 3032 arranged on the side of the first conveying line 10, the positioning claw 3031 is suitable for positioning the skeleton on the inner shell at the center of the inner shell, and the pressing mechanism 3032 is suitable for pressing against the skeleton to press the skeleton tightly on the first to-be-assembled part to form the second to-be-assembled part.

[0095] That is, the first conveying line 10 can convey the first to-be-assembled part of the outer shell and the inner shell on the tooling 101 to each assembly station; the skeleton feeding part 3011 of the first assembly component 301 can send the skeleton to the transfer channel 3012, and cooperate with the reciprocating movement of the moving fork 3013 to transfer the skeleton in the transfer channel 3012 to the position where the scale inhibitor feeding part 3014 is located, so as to facilitate the reception of the scale inhibitor; the rotating claw 3022 of the feeding assembly 302 can turn the skeleton containing the scale inhibitor by 180° and feed the turned skeleton to the inner shell of the first to-be-assembled part on the tooling 101 through the skeleton feeding claw 3021; the positioning claw 3031 of the second assembly component 303 positions the skeleton on the inner shell at the center of the inner shell and cooperates with the pressing mechanism 3032 to press the skeleton on the first to-be-assembled part.

[0096] Therefore, the first to-be-assembled part with the installed inner shell and outer shell is conveyed between each station on the first conveying line 10; the skeleton is transferred to the transfer channel 3012 by the skeleton feeding part 3011 in the first assembly component 301, and the skeleton on the transfer channel 3012 is transferred to the position where the scale inhibitor feeding part 3014 is located by the moving fork 3013; the skeleton containing the scale inhibitor is turned by 180° and installed in the inner shell of the first to-be-assembled part on the tooling 101 by the cooperation of the skeleton feeding claw 3021 and the rotating claw 3022 of the feeding assembly 302; the skeleton on the inner shell is positioned at the center of the inner shell and pressed on the first to-be-assembled part by the cooperation of the positioning claw 3031 and the pressing mechanism 3032 of the second assembly component 303; thereby the skeleton, the scale inhibitor, the outer shell and the inner shell of the filter are automatically assembled into the filter core body, the assembly efficiency of the filter is improved, and the quality of the product is ensured.

[0097] For the positional relationship of the pressing mechanism 3032, the positioning claw 3031 and the first conveying line 10, the pressing mechanism 3032 and the positioning claw 3031 are symmetrically arranged on both sides of the first conveying line 10. It can be understood that the pressing mechanism 3032 and the positioning claw 3031 are symmetrically arranged on both sides of the first conveying line 10, so that the pressing mechanism 3032 and the positioning claw 3031 can act separately to improve the action rhythm of the pressing mechanism 3032 and the positioning claw 3031, thereby improving the efficiency.

[0098] For the pressing mechanism 3032, the pressing mechanism comprises a pressing rod and a lifting driving mechanism. Specifically, the lifting driving mechanism is connected to the pressing rod to drive the pressing rod to lift and press the framework against the first component to be assembled. For the lifting driving mechanism, the lifting driving mechanism can be a cylinder structure, through which the pressing rod can be driven to lift and press the framework against the first component to be assembled. For the pressing rod, the pressing rod can be provided in a cylindrical shape, through which the framework can be pressed against the first component to be assembled to complete the installation of the framework and the scale inhibitor in the shell. For the framework feeding part 3011, the framework feeding part 3011 comprises a vibrating conveying mechanism and a material taking claw. Specifically, the material taking claw is arranged at the discharge port of the vibrating conveying mechanism to grab and transfer the framework to the transfer channel 3012. For the vibrating conveying mechanism, the vibrating conveying mechanism can be a lifting machine, a vibrating disc and a limiting block structure, through which the framework in the vibrating disc can be automatically supplemented and sent to the limiting block, so as to reduce the frequency of manual feeding and improve the continuous working capacity of the equipment.

[0099] For the scale inhibitor feeding part 3014, the scale inhibitor feeding part 3014 comprises a vibrating conveying mechanism and a material taking claw. Specifically, the material taking claw is arranged at the discharge port of the vibrating conveying mechanism to grab and transfer the scale inhibitor into the framework on the moving fork 3013 or grab and transfer the framework with the scale inhibitor to the rotating claw 3022.

[0100] It can be understood that the scale inhibitor on the discharge port of the vibrating conveying mechanism can be grabbed and transferred into the framework on the moving fork 3013 by the material taking claw, and then the framework with the scale inhibitor installed can be grabbed and transferred to the rotating claw 3022 by the material taking claw.

[0101] Wherein, the structure and working principle of the material taking claw are consistent with those of the material taking claw described above, and will not be described in detail here; the vibrating conveying mechanism can adopt the existing vibrating disc combined with a direct vibrating conveying channel structure.

[0102] For the position of the rotating claw 3022, the rotating claw 3022 is arranged between the material taking claw and the framework feeding claw 3021, and the clamping opening of the rotating claw 3022 is adapted to align with the framework on the material taking claw.

[0103] It can be understood that by arranging the rotating claw 3022 between the material taking claw and the framework feeding claw 3021, the framework with the scale inhibitor installed on the material taking claw can be rotated by 180° and quickly transferred to the framework feeding claw 3021, so that the framework with the scale inhibitor installed can be installed in the inner shell of the first component to be assembled on the tooling 101 in the correct posture.

[0104] For the rotating claw 3022, the rotating claw 3022 can be a rotating cylinder cooperation clamping claw structure. For the skeleton loading claw 3021, the structure and working principle of the skeleton loading claw 3021 are consistent with those of the taking claw, and will not be described in detail here.

[0105] For the moving fork 3013, the moving fork 3013 can be composed of a fork plate and two moving drive mechanisms; the fork plate has a plurality of spaced and arranged notches, each notch being adapted to clamp the skeleton.

[0106] It can be understood that the plurality of spaced and arranged notches can clamp the skeleton on the moving channel 3012 and then move it to the position where the scale inhibitor supply part 3014 is located, so as to facilitate the installation of the scale inhibitor; wherein the notches can be arranged to match the shape of the outer contour of the skeleton, and the number of notches can be three. It can be understood that, by cooperating the fork plate with the moving drive mechanism, the fork plate can be close to or away from the skeleton on the moving channel 3012, so as to realize the conversion between the clamping position and the avoiding position; by cooperating the fork plate with the moving drive mechanism, the fork plate can move between the inlet and the outlet of the moving channel 3012, so as to gradually move the skeleton to the position where the scale inhibitor supply part 3014 is located, so as to facilitate the installation of the scale inhibitor; wherein the moving drive mechanism and the moving drive mechanism can be a cylinder driven moving pair structure, and the moving stroke of the moving drive mechanism can match the pitch of the notches, so as to ensure that the skeleton can be accurately clamped when repeating the action.
