[0029] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] like Figure 1 , Figure 2 , Fig.10 , Fig.11 as well as Fig.12 As shown, this embodiment provides a device for assembling a nozzle with a filter element, which has a frame 1, and the top of the frame 1 is a work surface.

[0034] The turntable mechanism 2 is arranged on the worktable, and a positioning fixture 10 is arranged on the turntable mechanism 2. For example, the turntable mechanism 2 includes a fixed plate 9 and a turntable 8 arranged coaxially; the turntable 8 is rotatably arranged on the outer ring of the fixed plate 9, and a plurality of positioning fixtures 10 are arranged at intervals on the surface of the turntable 8. For example, six positioning fixtures 10 are arranged at equal intervals on the surface of the turntable 8. For example, the rotation angle of the turntable 8 can be controlled by the divider 12, and the motor 11 drives the divider 12 to rotate. Each time the motor 11 rotates, the divider 12 drives the turntable 8 to rotate to the position of a positioning fixture 10.

[0035] like Figure 3 , Figure 4 As shown, a nozzle feeding mechanism 3 and a first manipulator 6 are also provided on the working table of the frame 1; the nozzle feeding mechanism 3 is located on one side of the turntable mechanism 2; the first manipulator 6 has a clamping claw 14 for clamping the nozzle 34, and the first manipulator 6 is adapted to the discharge port of the nozzle feeding mechanism 3, and is used to place the nozzle 34 of the filter element 35 to be assembled at the discharge port of the nozzle feeding mechanism 3 on the positioning fixture 10. For example, a photoelectric detector 13 can be provided on the stationary fixed plate 9, and when the positioning fixture 10 is rotated into place, if the photoelectric detector 13 detects that there is no nozzle 34 on the positioning fixture 10, the nozzle 34 of the first manipulator 6 is placed on the positioning fixture 10. For example, the nozzle feeding mechanism 3 can adopt the existing nozzle feeding mechanism 3, which has a nozzle vibration plate 15, a straight rail 16, a straight vibration 17 and a dividing block 18. When in use, the nozzle 34 is poured into the nozzle vibration plate 15, and the nozzle vibration plate 15 vibrates to select the nozzle 34 in the required direction to flow into the straight rail 16. Since the straight rail 16 is installed on the straight vibration 17, the vibration of the straight vibration 17 makes the nozzle 34 enter the dividing block 18 in an orderly manner. When the sensor installed in the dividing block 18 detects the presence of the nozzle 34, the signal is transmitted to the first manipulator 6 to enable it to grab the material.

[0036] like Figure 5 , Figure 6 As shown, the filter element feeding mechanism 4 includes a filter element vibration plate 19, a material distribution component and a material pressing component. The material distribution component has a material distribution station and a material pressing station. The material pressing station is located below the material pressing component. The filter element vibration plate 19 transports the filter element 35 to the material distribution station, and the material distribution component transports the filter element 35 to the material pressing station one by one. When the positioning fixture 10 is transferred to the bottom of the material pressing station, the material pressing component presses the filter element 35 into the nozzle 34. Such a setting improves the assembly efficiency compared to relying on manual picking of the filter element.

[0037] like Figure 5 , Figure 6 , Figure 7 as well as Figure 8As shown, specifically, the material distribution component includes a material distribution positioning block, and the material pressing component includes a seat body 20 and a pressure head 21; the material distribution positioning block 22 is slidably arranged on the seat body 20, and the side of the material distribution positioning block 22 is arranged toward the outlet of the filter element vibration disk 19; wherein, the filter element vibration disk 19 screens the filter element 35 in the same way as the nozzle vibration disk 15 screens the nozzle 34, and the filter element 35 that meets the requirements in the direction can be screened out by vibration, and a track is also arranged on the side of the filter element vibration disk 19, and the screened filter elements 35 are arranged in a row on the track, and finally slide out from the outlet end of the track, and the filter element is supplied by the filter element vibration disk, which can free manpower and improve efficiency. A material distribution trough 24 is arranged on the side of the material distribution positioning block 22 facing the outlet of the filter element vibration disk 19, for example, the material distribution trough 24 can be a U-shaped hole, and the opening of the U-shaped hole is arranged toward the outlet of the filter element vibration disk 19. When the material distribution positioning block 22 slides to the material distribution station, the material distribution trough 24 is aligned with the discharge port of the filter element vibration disk 19 in the horizontal direction. At this time, the filter element 35 can enter the material distribution trough 24. Among them, the material distribution trough 24 can accommodate one filter element 35, so that only one filter element 35 can enter the material distribution trough 24 at a time. When the material distribution positioning block 22 slides to the material pressing station, the material distribution trough 24 is aligned with the positioning fixture 10 in the vertical direction. The pressure head 21 is telescopically arranged on the seat body 20, and the pressure head 21 presses the filter element 35 in the material distribution trough 24 downward into the nozzle 34 when the material distribution positioning block 22 slides to the material pressing station. With such a configuration, under the action of the material distribution positioning block, there is no need to manually place the filter element and align the filter element with the nozzle, and it is not easy to produce defective products.

[0038] For example, a support plate 23 can be provided on the seat body 20, and the support plate 23 can be provided in the horizontal direction. A chute 28 is provided on the support plate 23 along the sliding direction of the material distribution positioning block 22, and the material distribution positioning block 22 can be slidably provided in the chute 28. Such a configuration can ensure the movement accuracy of the material distribution positioning block 22. The track of the filter element vibration plate 19 extends into the support plate 23 so that its discharge port is connected with the chute 28, so that the filter element 35 can smoothly enter the material distribution trough 24 when the material distribution positioning block 22 is in the material distribution station. The chute 28 is provided with a clearance hole for the filter element 35 to pass through the support plate 23 when the material distribution positioning block 22 is in the material pressing station. Such a configuration can ensure that when the pressure head 21 presses the filter element 35 in the material distribution trough 24 downward, the bottom of the chute 28 will not block the filter element 35, so that the filter element 35 smoothly enters the nozzle 34 downward.

[0039] For example, the slot width of the dividing groove 24 gradually decreases in the direction away from the pressure head 21, the slot width of the end of the dividing groove 24 close to the pressure head 21 is larger than the diameter of the filter element 35, and the slot width of the end of the dividing groove 24 away from the pressure head 21 is smaller than the diameter of the filter element 35. Among them, the aperture of the end of the dividing groove 24 away from the pressure head 21 is slightly smaller than the diameter of the filter element 35. It can be understood that "slightly smaller than" here means that when the filter element 35 enters the end of the dividing groove 24 away from the pressure head 21, the filter element 35 contacts the inner wall of the dividing groove 24, and there is friction between the filter element 35 and the inner wall of the dividing groove 24, so that the filter element 35 is not easy to fall from the dividing groove 24. At the same time, when the pressure head 21 is pressed down, the pressure head 21 only needs to apply a small force, and the filter element 35 can be separated from the dividing groove 24, so as to avoid the filter element 35 being excessively squeezed by the dividing groove 24 and deformed. It is understandable that the width of the end of the distribution groove 24 close to the pressure head 21 is greater than the diameter of the filter element 35 , which can facilitate the filter element 35 to enter the distribution groove 24 .

[0040] Among them, the first driving member can be a first cylinder, the first cylinder 26 is arranged on the support plate 23, and the telescopic head of the first cylinder 26 is connected to the material dividing positioning block 22, which is used to drive the material dividing positioning block 22 to slide along the slide groove 28, so that the material dividing positioning block 22 slides back and forth between the material dividing station and the material pressing station.

[0041] The second driving member may be a second cylinder 27, which is disposed on the top of the seat body 20. The telescopic head of the second cylinder 27 extends downward and is connected to the pressure head 21, and is used to drive the pressure head 21 to perform telescopic movement. For example, a detector 25 for detecting whether there is a filter element 35 in the material distribution trough 24 may be disposed on the support plate 23. When the detector 25 detects that there is a filter element 35 in the material distribution trough 24, the first cylinder 26 drives the material distribution positioning block 22 to move from the material distribution station to the material pressing station. For example, the detector 25 may be a photoelectric sensor, an infrared camera, etc.

[0042] like Fig. 9As shown, the device for assembling a nozzle with a filter element further includes a shaping mechanism 5, which is arranged on the work surface of the frame 1 and located on one side of the turntable mechanism 2. The shaping mechanism 5 is located between the filter element loading mechanism 4 and the unloading mechanism 7. The shaping mechanism 5 includes a fixing frame 33, a third driving member and a shaping head 30. For example, the third driving member can be a third cylinder 29. The third cylinder 29 is arranged on the top of the fixing frame 33, and the telescopic head of the third cylinder 29 extends downward and is connected to one end of the shaping head 30; a closing groove is arranged on the end surface of the shaping head 30 away from the third cylinder 29, and the large end of the closing groove is arranged away from the third cylinder 29, the width of the large end of the closing groove is greater than the diameter of the nozzle 34, and the width of the small end of the closing groove is less than the diameter of the nozzle 34. For example, the closing groove can be a conical closing groove; when the closing groove is aligned with the nozzle 34 on which the filter element 35 has been assembled on the positioning fixture 10, the third cylinder 29 drives the shaping head 30 to press down so that the end of the nozzle 34 is inserted into the closing groove. At this time, as the shaping head 30 moves downward, the port of the nozzle 34 is squeezed and contracted. The nozzle 34 with the contracted port can prevent the filter element 35 from falling out from the end.

[0043] The shaping mechanism 5 further includes a limit plate 32 and a guide sleeve 31; the limit plate 32 is mounted on the fixing frame 33 in the horizontal direction, and a through hole is provided on the plate surface of the limit plate 32 to allow the shaping head 30 to pass through; the guide sleeve 31 is at least partially inserted into the through hole, and the shaping head 30 is inserted into the guide sleeve 31. For example, the guide sleeve 31 can be a sleeve with a T-shaped longitudinal cross section. After installation, the large end of the guide sleeve 31 is located outside the through hole and abuts against the edge of the through hole. With such a configuration, under the action of the limit plate 32 and the guide sleeve 31, the shaping head 30 can be prevented from swinging, thereby ensuring the accuracy of its movement.

[0044] Among them, a unloading mechanism 7 is also arranged on the working table of the frame 1. The structure of the unloading mechanism 7 can be the same as that of the first manipulator 6. The unloading mechanism 7 is arranged on one side of the turntable mechanism 2 and is located downstream of the shaping mechanism 5. It is used to remove the nozzle 34 after the port is shrunk from the positioning fixture 10.

[0045] When in use, the turntable 8 rotates counterclockwise, and the nozzle 34 is selected by the nozzle vibration plate 15 of the nozzle feeding mechanism 3, and then grabbed by the first manipulator 6 and placed in the positioning fixture 10 on the turntable 8. At the same time, other action mechanisms are also completing the material preparation actions. Among them, the filter element feeding mechanism 4 separates a filter element 35. When the positioning fixture 10 equipped with the nozzle 34 rotates to the bottom of the filter element feeding mechanism 4, the filter element feeding mechanism 4 pushes out the filter element 35 and presses it into the inner hole of the nozzle 34. When the nozzle 34 with the filter element 35 installed rotates to the bottom of the shaping mechanism 5, the shaping mechanism 5 closes the nozzle 34. When the closed nozzle 34 rotates to the bottom of the unloading mechanism 7, the material is taken out, and a cycle is completed.

[0046] In summary, the equipment for assembling nozzles with filter cartridges in this application, after implementation, all assembly parts are vibrated out by vibration screening, and automatic pre-installation, press-fitting and closing are completed. The equipment is stable and the efficiency is increased by more than 3 times. After eliminating the influence of human factors, the one-time qualified rate has been improved.

[0047] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
