[0002] An electronic expansion valve drives a gear reducer directly through the rotation of a stepper motor, and transmits power through a screw pair to realize the upward or downward movement of a valve needle to adjust the opening state of a valve port, thereby automatically adjusting the refrigerant flow rate. Among them, the axial member constituting the screw pair is a lead screw, on which a gear is sleeved, and the gear is positioned by a snap ring assembled in a card slot of the lead screw to prevent the product from losing steps or failing due to the nylon gear coming off.

[0029] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Please refer to Figure 1 , which is a schematic diagram of the overall structure of the circlip assembly device provided by the embodiment of the present application.

[0031] As shown in the figure, the circlip assembly device 100 mainly includes a turntable 10, a positioning seat 20, a circlip press-fitting mechanism 30, a lower pressing mechanism 40, an upper pushing mechanism 50, and a vibratory bowl mechanism 60.

[0032] Among them, the turntable 10 is in an overall disc shape and can rotate driven by a drive component (not shown in the figure). A plurality of positioning seats 20 are provided on the turntable 10 for positioning the axial component 70 for assembling the circlip 60. For example but not limited to, the axial component 70 can be a lead screw 71 assembled with a gear 72.

[0033] Please refer to Figure 2 and Figure 3 , where Figure 2 is a schematic diagram of the assembly relationship between the positioning seat 20 and the axial component 70, Figure 3 is Figure 1Front view of the circlip assembly device shown in the figure. The axial member 70 can be inserted and installed in the installation portion 21 of the positioning seat 20 to maintain a definite upright assembly posture. For the convenience of description, two directions in the rotation plane of the turntable 10 are defined: the first direction X and the second direction Y. The first direction X is the pressing direction of the circlip, and the second direction Y is the feeding direction of the circlip. The third direction Z is defined as the direction in which the axis of the axial member 70 extends, that is, the height direction perpendicular to the rotation plane of the turntable 10 shown in the figure.

[0034] In this embodiment, each positioning seat 20 is arranged close to the outer peripheral edge of the turntable 10, which is convenient for assembling the circlip at the circlip pressing station B. And each positioning seat 20 is arranged on the turntable 10 at intervals in the circumferential direction, which can avoid affecting or interfering with the relevant operations of the adjacent positioning seat 20 at the station.

[0035] In a specific implementation, a gear feeding station, a lead screw feeding station and a gear pressing station can be arranged on the upstream side of the circlip pressing station B, and a circlip detection station and a finished product discharging station can also be arranged on the downstream side of the circlip pressing station B, which can be determined according to the overall design of the production line and are not limited in the embodiments of the present application. Here, the "upstream side" and "downstream side" refer to the sequential relationship of the positioning seat stations formed by the rotation of the turntable 10.

[0036] Among them, the circlip pressing mechanism 30 includes a pushing block 311, and the circlip 60 is placed at the outer extending end of the pushing block 311. The pushing block 311 can move towards the lead screw 71 in the first direction X to press the circlip 60 into the circlip groove 711 of the lead screw 71. During the pressing process, the open end of the circlip 60 is pressed and deformed, and returns to its original state after being installed in place. Applying this solution, the circlip can be automatically and accurately positioned in the state of a small gap between the gear and the circlip groove.

[0037] In order to improve the stable reliability of the circlip 60 pressing operation, an inner concave portion 211 and an insertion hole 212 are opened on the installation portion 21 of the positioning seat 20, and the inner concave portion 211 and the insertion hole 212 are communicated. The insertion hole 212 is used to be adapted to the rod section of the lead screw 71 on the side where the circlip groove 711 is located, and the inner concave portion 211 is used to accommodate the gear 72 and to form a circlip insertion space C. After the axial member 70 is inserted in place, a part of the rod section of the lead screw 71 can be inserted into the insertion hole 212, and the gear 72 can be placed inside the inner concave portion 211. The circlip insertion space C is formed in the inner concave portion 211 below the gear 72, and the circlip groove 711 of the lead screw 71 is located in the circlip insertion space C, so that the pushing block 311 can extend into it to complete the circlip pressing operation. Please refer to Figure 4 , this figure is Figure 3 The enlarged view of part D.

[0038] During the circlip press-fitting operation, the rod section of the lead screw 71 adapted to the insertion hole 212 is the bottom force-bearing position. Here, setting the circlip groove 711 close to this force-bearing position can effectively improve the force-bearing state and ensure the stable and reliable operation of the circlip press-fitting operation.

[0039] Furthermore, it may further include a downward pressing mechanism 40, which includes a downward pressing part 41 and a downward pressing driving component 42. Please refer to Figure 5 together, which shows Figure 1 the structural schematic diagram of the downward pressing mechanism shown in

[0040] Driven by the driving force output by the downward pressing driving component 42, the downward pressing part 41 can move downward to the downward pressing station. The downward pressing part 41 has a mounting hole 411 adapted to the other rod section of the lead screw 71. Again, as shown in Figure 4 , after moving to the downward pressing station, it is sleeved on the other rod section of the lead screw 71, which can further ensure the stable and reliable execution of the circlip press-fitting operation.

[0041] Combined with Figure 5 shown, the downward pressing mechanism 40 may include a first mounting seat 43. The downward pressing part 41 and the downward pressing driving component 42 may be integrally arranged on the first mounting seat 43 and assembled and fixed to the turntable 10 through the first mounting seat 43. Among them, the downward pressing part 41 is slidably arranged on the first mounting seat 43 along the third direction Z. A chute is arranged on one of them, and a slide rail is arranged on the other. The two form a sliding pair through the adapted chute and slide rail; the output end of the downward pressing driving component 42 is connected to the downward pressing part 41 to drive the downward pressing part 41 to slide up and down relative to the first mounting seat 43.

[0042] In specific implementation, different forms of downward pressing driving components 42 can be selected according to needs. For example, but not limited to, a cylinder, an oil cylinder or a linear motor that outputs a linear driving force.

[0043] It can be understood that for an axial part with a short axial dimension, this downward pressing mechanism can be an optional component.

[0044] Further optionally, the automatic feeding of the circlip can be realized through the vibrating bowl mechanism 50. Please refer to Figure 1 and Figure 6 , where Figure 6 is Figure 1 the structural schematic diagram of the linear vibration channel shown in

[0045] In this implementation scheme, the discharge port 51 of the vibrating bowl mechanism 50 is provided with a linear vibration channel 52. The linear vibration channel 52 has a conveying groove 521 opened along the first direction, and the conveying groove 521 is communicated with the feeding groove of the circlip press-fitting mechanism 30.

[0046] Here, by taking advantage of the structural characteristics of the shape and dimensions of the circlip 60, the vibrating bowl mechanism 50 can sequentially send the circlips to the linear vibrating channel 52 along the second direction Y, and feed them through the conveying groove 521 of the linear vibrating channel 52 to the feeding groove of the circlip pressing mechanism 30. Figure 7 Taking the circlip 60 of the indicated model as an example, the outer diameter of the circlip is φ6mm, and the maximum distance from the outer circle to the open end of the circlip is 5.3mm. Correspondingly, the groove width of the linear vibrating channel 52 is 5.4mm. That is to say, the groove width of the conveying groove 521 of the linear vibrating channel 52 is adapted to the maximum distance from the outer circle of the circlip 60 to the open end of the circlip.

[0047] In this way, while ensuring the smooth feeding of the circlips, the rotation of the circlips in the horizontal plane can be restricted, the consistency of the circlips in the horizontal direction can be guaranteed, automatic and continuous feeding can be realized, and the labor intensity of the operator can be effectively reduced.

[0048] In other possible implementation solutions, for circlips of other model sizes, by adaptively setting the groove width dimension of the conveying groove 521 of the linear vibrating channel 52, automatic and continuous feeding can also be realized.

[0049] It should be noted that the function of the vibrating bowl mechanism 50 to discharge materials by vibration can be realized by existing technologies, so it will not be elaborated in this article.

[0050] In this implementation solution, the circlip pressing mechanism 30 includes a circlip pressing-in mechanism 31 and a circlip misfeeding mechanism 32. Please refer to Figure 8 , this figure is Figure 1 the overall structural schematic diagram of the circlip pressing mechanism shown in

[0051] As shown in the figure, the circlip pressing-in mechanism 31 and the circlip misfeeding mechanism 32 are integrally arranged on the second mounting seat 33. The circlip misfeeding mechanism 32 is used to separate the circlips conveyed from the vibrating bowl mechanism 50 side and place them on the pusher block 311 of the circlip pressing-in mechanism 31. The circlip pressing-in mechanism 31 is used to push the circlip to the circlip insertion space C to realize the reliable pressing between the circlip 60 and the lead screw 71.

[0052] Please also refer to Figure 9 , this is Figure 8 the structural schematic diagram of the circlip misfeeding mechanism shown in Figure 9 As shown, the circlip misfeeding mechanism 32 includes a misfeeding part 321 and an adsorption press head 322.

[0053] Among them, a misfeeding groove 3211 serving as a feeding port is formed on the misfeeding part 321 to accommodate the circlips 60 conveyed through the conveying groove 521. The misfeeding part 321 is connected to the output end of the misfeeding driving component 323 and can move along the first direction X under the drive of the misfeeding driving component 323 to separate a single circlip and push the circlip to the lower part of the adsorption press head 322.

[0054] In a specific implementation, the body of the misfeeding driving component 323 is fixedly arranged on the fifth mounting seat 328, and the misfeeding part 321 is slidably arranged on the fifth mounting seat 328 along the first direction X. The fifth mounting seat 328 can be fixedly arranged on the second mounting seat 33.

[0055] Wherein, the lower end of the adsorption head 322 has an opening, and an internal channel communicating with the opening is arranged in the body of the adsorption head 322. The internal channel is connected to a negative pressure suction device (not shown in the figure) to form a negative pressure adsorption effect at the end of the adsorption head 322. The adsorption head 322 is connected to the pick-and-place driving component 324 and can move up and down under the drive of the pick-and-place driving component 324. When the misfeeding part 321 pushes the circlip 60 to the lower part of the adsorption head 322, the adsorption head 322 can move downward under the drive of the pick-and-place driving component 324 and press the circlip 60 located in the misfeeding groove 3211. At this time, negative pressure suction is started, and negative pressure is established through the internal channel of the adsorption head 322 to adsorb the circlip 60 at its bottom end face, and the pick-and-place driving component 324 can be reset. Here, the number and positional relationship of the openings of the internal channel can be determined according to the overall design requirements of the product. The embodiments of the present application do not make limitations.

[0056] In a specific implementation, the adsorption head 322 and the pick-and-place driving component 324 can be integrally arranged on the third mounting seat 326. The body of the pick-and-place driving component 324 is fixedly arranged on the third mounting seat 326, and the adsorption head 322 is slidably arranged on the third mounting seat 326 along the third direction Z.

[0057] The third mounting seat 326 is slidably arranged on the fourth mounting seat 327 along the second direction Y, and the fourth mounting seat 327 is fixedly arranged on the second mounting seat 33. The third mounting seat 326 is connected to the transfer driving component 325, and under the drive of the transfer driving component 325, it can drive the third mounting seat 326 and the adsorption head 322 and the pick-and-place driving component 324 arranged thereon to move along the second direction Y.

[0058] After the circlip 60 is adsorbed at the bottom end face of the adsorption head 322, the pick-and-place driving component 324 can drive the adsorption head 322 and the circlip to move upward, and then under the drive of the transfer driving component 325, the adsorption head 322 moves along the second direction Y towards the pushing block 311 of the circlip pressing mechanism 31.

[0059] When the adsorption head 322 moves to the outer extension end of the pushing block 311, the pick-and-place driving component 324 can drive the adsorption head 322 and the circlip to move downward. When the circlip 60 reaches the profiling groove 3111 at the outer extension end of the pushing block 311, the negative pressure suction is stopped, the circlip 60 is separated from the adsorption head 322, and the pick-and-place driving component 324 can be reset again.

[0060] The profiling groove 3111 has a contour substantially the same as the outer circle of the circlip so as to maintain a stable and reliable attitude within the groove. Of course, in other possible implementation solutions, the profiling groove 3111 for supporting the circlip may also adopt a circlip placement groove with other structural forms, rather than being limited to the profiling groove shown in the figure.

[0061] Please also refer to Figure 10 which is Figure 8 a schematic structural view of the circlip pressing mechanism shown in Figure 10 As shown in Figure 10 , the circlip pressing mechanism 31 includes a pressing drive member 312. The pusher block 311 is connected to the pressing drive member 312 and can move along the first direction X under the drive of the pressing drive member 312 to implement the pressing operation of the circlip.

[0062] In a specific implementation, the pressing drive member 312 and the pusher block 311 can be integrally arranged on the sixth mounting seat 313. The body of the pressing drive member 312 is fixedly arranged on the sixth mounting seat 313, and the pusher block 311 is slidably arranged on the sixth mounting seat 313 along the first direction X, and a sliding pair is established with the sixth mounting seat 313 through a slider 3113 located at the inner end side of the pusher block 311.

[0063] Specifically, an avoidance opening 3112 is formed at the bottom of the profiling groove 3111 of the pusher block 311. Please also refer to Figure 11 and Figure 12 and Figure 13 where Figure 11 is Figure 10 a schematic structural view of the pusher block shown in Figure 12 showing a schematic view of the relative position between the axial member and the pusher block in the press-fitting state, Figure 13 is Figure 12 the E-direction projection view of

[0064] As shown in Figure 11 , the avoidance opening 3112 extends to the outer extending end face of the pusher block 311 to accommodate the lead screw 71 below the circlip groove 711, ensuring reliable support for the circlip 60 and accurate press-fitting.

[0065] In order to further improve the reliable retention of the circlip 60 in the profiling groove 3111 during the press-fitting process, internal channels 3113 can be arranged inside the body of the pusher block 311. The external opening of the internal channel 3113 extends to the bottom surface of the profiling groove 3111 and can be connected to a negative pressure suction device (not shown in the figure) through the slider 3113 to form a negative pressure adsorption effect at the bottom of the profiling groove 3111, adsorbing the circlip 60 at the outer extending end of the pusher block 311. After the circlip 60 is completely press-fitted onto the lead screw 71, the negative pressure suction is stopped, and the press-in driving component 312 is reset. Here, on the bottom surface of the profiling groove 3111, the number and positional relationship of the external openings of the internal channels 3113 can be determined according to the overall design requirements of the product. The embodiments of the present application are not limited in this regard.

[0066] In specific implementation, the forms of the press-in driving component 312, the misfeeding driving component 323, the pick-and-place driving component 324, and the transfer driving component 32 can also be selected as needed. For example, but not limited to, cylinders, oil cylinders, or linear motors that output linear driving forces. It should be understood that the main functional components of each driving component are not the core inventive points of the present application, and those of ordinary skill in the art can implement them based on the prior art, so they will not be elaborated herein.

[0067] It should be noted that the ordinal numbers used in the above embodiments provided by this implementation manner are used to distinguish the same functional components or structures. It should be understood that the application of the above ordinal numbers is only used to distinguish different limited objects and does not constitute a substantial limitation on the technical solution claimed in the present application.

[0068] The above are only the preferred implementation manners of the present invention. It should be pointed out that for those of ordinary skill in the art in the technical field, several improvements and refinements can be made without departing from the principle of the present invention, and these improvements and refinements should also be regarded as the protection scope of the present invention.
