Description

Technical Field

[0001] The present invention relates to the technical field of solenoid valve processing devices, and in particular to an assembly mechanism of a valve core body and a valve body of a solenoid valve. Background Art

[0002] As an important fluid control component, solenoid valves are widely used in various industries, such as oil circuit control in automobiles and automatic reagent addition control in chemical product processing.

[0003] The main components of a solenoid valve include a spool and a valve body, with pins located on the spool. Inserting the spool into the valve body requires careful alignment and adjustment of the pins' orientation and angle. Failure to do so can prevent the solenoid valve from being assembled or significantly impact its performance. Consequently, the current assembly process still relies heavily on manual labor, making it difficult to meet assembly efficiency and product precision requirements. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides an assembly mechanism of the valve core body and the valve body of a solenoid valve, which can automatically complete the flipping and angle adjustment of the valve core body and automatically engage it with the valve body, greatly improving the assembly efficiency of the solenoid valve.

[0005] The assembly mechanism of the valve core body and valve body of the solenoid valve of the present invention includes a machine platform, a turntable is provided on the machine platform, a plurality of workstations are provided on the turntable, and the machine platform also includes a valve core body feeding portion, a valve core body turning portion and a crimping portion for pressing the valve core body into the valve body. The valve core body feeding portion can convey the valve core body to the valve core body turning portion and the crimping portion. Therefore, by utilizing the assembly mechanism of the present invention, the valve core body can be turned over by the action of the valve core body turning portion and can be automatically pressed into the valve body by the action of the crimping portion. The valve core body feeding portion of the present invention can convey the valve core body to the valve core body turning portion and the crimping portion, making the overall integration of the assembly mechanism of the present invention higher and the working efficiency higher.

[0006] Furthermore, the valve core body feeding part includes a valve core body feeding rack, a valve core body feeding track is provided on the valve core body feeding rack, and also includes a valve core body feeding motor and a manipulator, and the manipulator can move along the valve core body feeding track under the drive of the feeding motor.

[0007] Furthermore, each station of the turntable is provided with a valve body clamping portion for securing the valve body. The valve body clamping portion includes a clamping plate that matches the valve body and a clamping plate that can rotate toward or away from the clamping plate. Thus, the valve body can be clamped at the station of the turntable through the cooperation of the clamping plate and the clamping plate.

[0008] Furthermore, the manipulator includes at least three clamping fingers capable of clamping the valve core body in a circumferential direction, and the clamping fingers can move along the radial direction of the valve core body.

[0009] Furthermore, the valve core body turning portion includes a rotating head and a rotation driving device connected to the rotating head, and the rotating head is provided with a clamping claw for clamping the valve core body.

[0010] Furthermore, the valve core body flipping portion also includes a valve core body placement plate and a lifting cylinder located below the valve core body placement plate. The clamping claw is located above the valve core body placement plate. A receiving groove for the valve core body is provided in the middle of the valve core body placement plate. The push rod of the lifting cylinder can pass through the receiving groove and lift the valve core body placed therein. The manipulator can move the magnetic core body to the valve core body placement plate. Thus, the valve core body can be lifted to the clamping claw and clamped by the clamping claw under the action of the lifting cylinder, and then rotated by the rotation drive device. Providing a certain distance between the clamping claw and the valve core body placement plate can avoid affecting the rotation of the valve core body.

[0011] Furthermore, the crimping part includes a crimping head that can move up and down and a lower tightening cylinder located below the valve body. One station of the turntable is a crimping station, and the crimping head is arranged above the crimping station.

[0012] Furthermore, the device further includes a valve body guide disposed adjacent to the crimping station. The valve body guide includes a slot that can be moved toward or away from the valve core located at the crimping station, into which the pins of the valve core can be snapped. Thus, the placement angle of the valve core can be adjusted and guided, ensuring a high degree of precision in the resulting press-assembled solenoid valve.

[0013] Furthermore, one of the stations of the turntable is an oiling station, which is upstream of the crimping station and is provided with a valve body oiling portion. Thus, the valve body is first oiled before crimping, which facilitates the pressing of the valve core.

[0014] Furthermore, the valve body oiling unit includes an oil spray gun with a nozzle disposed at its lower end, and an oil receiving pan that can be moved below the nozzle. Therefore, when oiling is not required, the oil receiving pan can be moved below the nozzle to prevent oil from contaminating the valve body. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0035] The automatic assembly mechanism of the valve core body and the valve body of the solenoid valve of the present invention is used to assemble the valve core body and the valve body of the solenoid valve. Figure 11 The valve core body 71 and the valve body 72 are assembled together, and a pin 711 is provided on the valve core body 71.

[0036] See attached Figure 1 Figure 5 shows a preferred embodiment of the automatic assembly mechanism for the valve core and valve body of the solenoid valve of the present invention. The mechanism comprises a machine platform with a turntable 1 disposed thereon. The turntable 1 is provided with multiple workstations, each of which is equipped with a valve body clamping portion 2. The turntable 1 is provided with a valve body oiling station 11 and a crimping station 12. In this embodiment, the oiling and crimping stations 12 are adjacently arranged, but they can also be spaced apart as needed. The assembly mechanism of the present invention includes a valve core loading section, a valve core turning section, a valve body oiling section, and a crimping section for pressing the valve core into the valve body.

[0037] See attached Figure 6 and 7 As shown, the valve body clamping part 2 of the present invention includes a clamping plate 21 that matches the valve body and a splint 22 that can rotate toward or away from the clamping plate 21. The splint 22 of the present invention is provided with a clamping position that matches the shape of the valve body on the side close to the valve body. The valve body clamping part 2 of the present invention is provided with two splints 22, which are symmetrically arranged on both sides of the clamping plate 21. The two splints 22 are respectively hingedly connected to a rocker rod 23, and also include a rotating shaft 24 passing through the splint 22. The rocker rod 23 is connected to the push rod through a connecting block. The push block is located between the two rocker rods 23. A spring 25 is provided on the outer sleeve of the push rod, and a limiting edge 26 that can abut against the spring 25 is provided on the end of the push rod 28 close to the valve body to be clamped. A protective shell 29 is also provided on the outside of the push rod 28 and the spring 25. See the attached Figure 8 As shown, a rotatable clamping cylinder 27 is also provided in the center of the turntable 1. The clamping cylinder 27 can be rotated in turn to abut against the rocker rod 23 of each workstation and push it toward the outer edge of the turntable 1. At this time, the clamping plate 22 is clamped toward the side of the clamping plate 21. When the clamping cylinder 27 is not working, the rocker rod 23 is reset under the action of the spring 25, and the distance between the clamping plate 22 and the clamping plate 21 is increased, which makes it easier to take and place the valve body.

[0038] The valve core body feeding portion of the present invention includes a feeding track 31, a valve core body feeding frame 32, a valve core body feeding motor 33, and a manipulator 34. The manipulator 34 of the present invention includes at least three clamping fingers 341 that can clamp the valve core body in the circumferential direction. The clamping fingers 341 of the present invention are pneumatic fingers that can move along the radial direction of the valve core body, thereby achieving clamping of the valve core body. A valve core body feeding slide 35 is provided on the valve core body feeding frame 32, and also includes a slide 36 connected to the valve core body feeding slide 35. The valve core body feeding motor 33 can drive the slide 36 to move. The manipulator 34 can move left and right along the valve core body feeding slide 35 under the action of the valve core body feeding motor 33. The slide 36 of the present invention can be moved by a conveyor belt or conveyor chain connected to the feeding motor 33. It can also be achieved by a screw rod connected to the valve core body feeding motor 33 to achieve reciprocating movement along the length direction of the valve core body feeding slide 35. A lifting cylinder connected to the manipulator 34 is also provided on the slide plate 36, so that the manipulator 34 can be moved in the height direction.

[0039] One end of the valve core loading rack 32 is located near the loading track 31, and the other end is located near the crimping station 12 of the turntable 1. The turning section is located below the longitudinal center of the valve core loading rack 32. A tray 37 for holding valve cores is located on the loading track 31. A robot 34 can grab a valve core from the tray 37 and move it along the valve core loading slide 35 to the valve core turning section.

[0040] See attached Figure 9 As shown, the valve core flipping unit of the present invention includes a rotating head 41 and a rotating cylinder 42 connected to the rotating head 41. A clamping jaw 43 for gripping the valve core is provided on the rotating head 41. A valve core placement plate 44 is provided below the clamping jaw 43. A lifting cylinder 45 is provided below the valve core placement plate 44. A receiving groove 441 for receiving the valve core is provided in the middle of the valve core placement plate 44. The middle portion of the bottom of the receiving groove 441 is hollowed out. The push rod of the lifting cylinder 45 can pass through the receiving groove 441 and lift the valve core placed therein. The manipulator 34 moves the valve core body along the valve core body loading rack 32 to above the valve core body placement plate 44 and then releases it, allowing the valve core body to fall into the accommodating groove 441. Subsequently, the push rod of the lifting cylinder 45 extends upward, and when the valve core body is lifted to the position of the clamping claw 43, the clamping claw 43 clamps the valve core body, and the rotating head 41 rotates 180 degrees driven by the rotating cylinder 42. At this time, the manipulator 34 again clamps the valve core body after adjusting the direction and moves it to the crimping part.

[0041] The valve body oiling part of the present invention is arranged above the valve body oiling station 11 of the turntable 1, see the attached Figure 10As shown, the oil spray gun 51 includes an oil spray gun 51 with a nozzle 511 disposed at its lower end. An oil receiving pan 52 is also disposed below the nozzle 511. The oil receiving pan 52 also includes a translation cylinder 53 for moving the oil receiving pan 52. When oil spraying is not in progress, the oil receiving pan 52 is located below the nozzle 511 to prevent oil droplets dripping from the nozzle 511 from contaminating the valve body. When oil spraying is required on the valve body, the oil receiving pan 52 is driven laterally by the translation cylinder 53, aligning the nozzle 511 with the valve body below and spraying oil. The oil spray gun 51 of the present invention can be moved up and down by the cylinder 53. When oil spraying is required on the inner cavity of the valve body, the oil receiving pan 52 is moved laterally by the translation cylinder 53, aligning the nozzle 511 of the oil spray gun 51 with the valve body and spraying oil. After oil spraying is completed, the oil spray gun 51 moves upward, and the oil receiving pan 52 is moved back below the nozzle 511 by the translation cylinder 53.

[0042] The crimping part of the present invention includes a crimping head 61 that can move up and down and a lower tightening cylinder 62 located below the valve body. The crimping head crimping part 61 moves up and down under the action of the crimping cylinder, and the valve body that has been sprayed with oil rotates to the crimping station 12 under the drive of the turntable 1. When the manipulator 34 moves to the station where the crimping part is located, it loosens the valve core body, and the valve core body falls into the valve body. At this time, the manipulator 34 moves away, the crimping head 61 moves downward and presses the valve core body and the valve body tightly. At the same time, the lower tightening cylinder 62 lifts the valve body upward, thereby clamping the valve core body into the valve body.

[0043] As a preferred embodiment of the present invention, a valve body guide is provided near the crimping station 12. The valve body guide includes a slot 63 that can move toward or away from the valve core located at the crimping station 12, and a slider 64 connected to the slot 63. The slider 64 is driven by a pneumatic cylinder. The width of the slot 63 matches the pins on the valve body, preferably slightly larger than the width of the pins 711 of the valve core. Therefore, when the slot 63 moves toward the valve core, it engages with the pins of the valve core and corrects the placement of the valve core. Before the valve core is pressed into the valve body, the slot 63, driven by the slider 64, approaches the valve core and guides the position of the pins. After the guidance is completed, the slot 63 retreats, and the crimping head 61 of the crimping section further presses the valve core into contact with the valve body. Therefore, guiding the valve core before crimping ensures the processing accuracy of the solenoid valve and reduces the defective product rate.

[0044] The above embodiments are only for illustrating the technical concept and features of the present invention. Its purpose is to enable people familiar with this technology to understand the content of the present invention and implement it. It cannot be used to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
