Description

Technical Field

[0001] The invention relates to the technical field of solenoid valve production, in particular to an automatic assembly line and an assembly process for an O-ring of a solenoid valve. Background Art

[0002] During the processing of the solenoid valve body, the armature, rubber sleeve, pole shoe, cartridge and casting need to be combined into the solenoid valve body B, and then the O-ring is manually put on. During the process of putting on the O-ring, it is necessary to manually use tweezers to grab an O-ring and use tweezers to open the O-ring and put it on the solenoid valve body B. The labor intensity is high and the assembly efficiency of the O-ring is low.

[0003] Chinese patent CN217702173U discloses an O-ring assembly mechanism for a solenoid valve, which includes a positioning and transfer jig, a vibrating plate, an O-ring grabbing robot, a straight guide rail connected between the vibrating plate and the positioning and transfer jig, and a positioning and transfer jig that displaces the last O-ring on the straight guide rail from the straight guide rail; the O-ring grabbing robot is used to grab an O-ring on the positioning and transfer jig that is displaced from the straight guide rail.

[0004] The above scheme realizes the positioning of the O-ring, which facilitates the automatic assembly of the O-ring and the solenoid valve, greatly improving the efficiency of the valve body assembly. However, with the above scheme, after the O-ring is transported, it needs to be clamped by a four-claw cylinder. At that time, since the O-ring is an elastic material, it is easy to deform during the clamping process, which causes the O-ring to fall off from the four-claw cylinder. At the same time, when the vibration plate transports the O-ring to the bottom of the four-claw cylinder, it needs to be positioned once, and the four-claw cylinder needs to position it again when grabbing the O-ring and moving it to the fixture, which increases unnecessary assembly time. At the same time, when the O-ring is removed, the O-ring will be damaged. Summary of the Invention

[0005] In response to the above problems, an automatic assembly line and assembly process for an electromagnetic valve O-ring are provided, wherein the first linear drive is in a semi-extended state, the lifting device is in an extended state, the vibrating plate transports the O-ring to the work platform, the positioning device positions the O-ring at the drop groove, the O-ring falls from the drop groove to the positioning column, the lifting device retracts, the unfolding device starts and drives the O-ring to unfold, the manipulator aligns the electromagnetic valve to be installed at the positioning column, the O-ring contacts the pushing device under the drive of the unfolding device, the pushing device and the first linear drive are started synchronously, the pushing device drives the O-ring to roll on the unfolding device, the first linear drive drives the positioning column to descend, and finally the O-ring is sleeved on the electromagnetic valve to be installed, so that the device reduces multiple positioning processes, improves work efficiency, and avoids the phenomenon of O-ring being damaged during installation.

[0044] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Reference Figure 1-Figure 3 and Figures 8-10: An automatic assembly line for solenoid valve O-rings, comprising a base 1, a vibrating plate 2 for conveying O-rings and a positioning and conveying device 3; the positioning and conveying device 3 comprises a positioning device 31, a working platform 32, a lifting device 33, a first linear drive 34, a positioning column 35, an unfolding device 36, a pushing device 37 and a moving device 38; the working platform 32 is arranged on the side of the vibrating plate 2 close to the base 1, the working platform 32 is used to receive the O-rings conveyed by the vibrating plate 2, and a drop groove is provided on the working platform 32; the positioning device 31 is arranged on the working platform 32, the positioning device 31 comprises a first pushing device 311 and a second pushing device 312, and the positioning device 31 is used to push the O-rings on the working platform 32 To the drop groove; the positioning post 35 is arranged below the drop groove, and the O-ring passes through the drop groove and is sleeved on the positioning post 35; the expansion device 36 is arranged on the positioning post 35, and the expansion device 36 is used to expand the O-ring; the first linear drive 34 is arranged below the positioning post 35, and the output end of the first linear drive 34 is fixedly connected to the positioning post; the lifting device 33 is arranged below the first linear drive 34, and the lifting device 33 drives the first linear drive 34 to rise and fall; the moving device 38 is arranged below the lifting device 33, and the moving device 38 can drive the lifting device 33 to move horizontally; the pushing device 37 is arranged on one side of the expansion device 36, and the pushing device 37 can push the expanded O-ring onto the solenoid valve.

[0046] There is an O-ring in the vibration disk 2. During assembly, the vibration disk 2 will transport the O-ring to the working platform 32. The positioning device 31 on the working platform 32 will position the O-ring. The first pushing device 311 can push the O-ring to the side away from the vibration disk 2. Then the second pushing device 312 can push the O-ring to the drop groove. At this time, the positioning post 35 is located below the drop groove. The O-ring passes through the drop groove and is sleeved on the positioning post 35. Then the lifting device 33 drives the first linear drive 34 to descend. Since the positioning post 35 is set on the output end of the first linear drive 34, The positioning post 35 will descend along with the first linear drive 34, and then the moving device 38 will drive the lifting device 33 to leave the falling groove. At the same time, the unfolding device 36 will start, and the unfolding device 36 will expand the O-ring on the positioning post 35. At this time, the inner radius of the O-ring will gradually increase. At the same time, the first linear drive 34 will drive the O-ring on the unfolding device 36 to rise, so that the O-ring is located on one side of the pushing device 37. When the unfolding device 36 is fully opened, the outer ring of the O-ring will contact the pushing device 37, and the pushing device 37 can drive the O-ring to roll on the unfolding device 36. Before the pushing device 37 drives the O-ring to roll on the unfolding device 36, it is necessary to use a robot to align the solenoid valve to be assembled on the upper part of the positioning column 35, and then the first linear drive 34 drives the positioning column 35 to descend, and at the same time, the pushing device 37 drives the O-ring to roll on the unfolding device 36. As the first linear drive 34 continues to descend, the O-ring will roll to the location where the solenoid valve is to be installed under the drive of the pushing device 37, so that the device reduces multiple positioning processes, improves work efficiency, and avoids the phenomenon of O-ring damage during installation.

[0047] Reference Figure 9 and Figure 10 : The expansion device 36 includes a pump body 361, a push rod 362 and an expansion plate 363; the pump body 361 is arranged on one side of the positioning column 35; a push groove is opened on the side wall of the positioning column 35, and the push groove is evenly distributed around the axis of the positioning column 35, and the push rod 362 is slidably arranged in the push groove along the depth direction of the push groove; the expansion plate 363 is fixedly arranged on the end of the push rod 362 away from the push groove, and the pump body 361 is used to drive the push rod 362 to slide in the push groove.

[0048] When the lifting device 33 descends, the pump body 361 will start, and the pump body 361 will drive the push rod 362 located in the push groove to extend, thereby causing the expansion plate 363 set on one end of the push rod 362 to extend. The extended expansion plate 363 will expand the O-ring. When the inner diameter of the O-ring is the same as the diameter of the solenoid valve to be assembled, the pushing device 37 will drive the O-ring to move toward the solenoid valve.

[0049] Reference Figure 2 and Figure 8: The lifting device 33 includes a second linear drive 331, a guide assembly 332 and a containing shell 333; the containing shell 333 sleeves the first linear drive 34 therein, and the positioning column 35 slides with the upper part of the containing shell 333; the second linear drive 331 is vertically arranged below the containing shell 333, and the output end of the second linear drive 331 is fixedly connected to the containing shell 333; the guide assembly 332 is vertically arranged on one side of the second linear drive 331, and the guide assembly 332 slides with the containing shell 333.

[0050] When the O-ring falls on the positioning column 35, the second linear drive 331 will retract, and the second linear drive 331 will drive the containing shell 333 to descend. Since the first linear drive 34 is fixedly arranged in the containing shell 333, the first linear drive 34 will also descend. The guide assembly 332 arranged on one side of the second linear drive 331 can ensure that the containing shell 333 is more stable when it is driven to move by the second linear drive 331.

[0051] Reference Figure 5 and Figure 8 : The pushing device 37 includes a first rotary driver 371, a transmission assembly 372, a pushing seat 373 and a roller 374; the first rotary driver 371 is horizontally arranged on one side of the positioning column 35; the pushing seat 373 is arranged on the side of the first rotary driver 371 close to the positioning column 35; the roller 374 is rotatably arranged on the pushing seat 373; the two ends of the transmission assembly 372 are respectively connected to the output end of the first rotary driver 371 and the roller 374, and the first rotary driver 371 drives the roller 374 to rotate through the transmission assembly 372.

[0052] When the unfolding device 36 drives the O-ring to unfold and comes into contact with the pushing device 37, the first rotary driver 371 is started. It is worth noting that when the O-ring comes into contact with the pushing device 37, the O-ring comes into contact with the roller 374. The first rotary driver 371 drives the roller 374 to rotate through the transmission assembly 372, and the roller 374 can drive the O-ring to roll on the unfolding device 36.

[0053] Reference Figure 3 and Figure 4 : The first pushing device 311 includes a second rotary driver 3111, a screw rod 3112 and a first push plate 3113; the second rotary driver 3111 is horizontally arranged above the working platform 32; the screw rod 3112 is fixedly arranged on the output end of the second rotary driver 3111; the first push plate 3113 is slidably arranged on the working platform 32 along the axial direction of the screw rod 3112, the screw rod 3112 passes through the first push plate 3113, and the screw rod 3112 is threadedly engaged with the first push plate 3113.

[0054] The second rotary driver 3111 is preferably a servo motor. When the vibration disk 2 transports the O-ring to the working platform 32, the second rotary driver 3111 will start, and the second rotary driver 3111 drives the screw rod 3112 to rotate. The first push plate 3113 threadedly engaged with the screw rod 3112 will drive the O-ring to move toward the side away from the vibration disk 2 under the action of the screw rod 3112.

[0055] Reference Figure 3 and Figure 4 : The second pushing device 312 includes a third linear drive 3121 and a second push plate 3122; the third linear drive 3121 is horizontally arranged on one side of the drop groove, the output end of the third linear drive 3121 points to the drop groove, and the axis of the output shaft of the third linear drive 3121 is perpendicular to the axis of the screw rod 3112; the second push plate 3122 is fixedly arranged on the output end of the third linear drive 3121.

[0056] When the first pushing device 311 finishes running, the third linear driver 3121 starts, and the third linear driver 3121 drives the second push plate 3122 to extend toward the drop groove, so that the O-ring will be pushed by the second push plate 3122 and finally fall from the drop groove.

[0057] Reference Figure 4 and Figure 7 : The positioning and conveying device 3 also includes a temporary storage component 321, which includes a telescopic plate 3211 and a fourth linear drive 3212; the fourth linear drive 3212 is horizontally arranged above the working platform 32 where a drop groove is provided; the telescopic plate 3211 has a turning structure, and the telescopic plate 3211 can be slidably arranged in the drop groove, and the fourth linear drive 3212 drives the telescopic plate 3211 to slide.

[0058] When the second pushing device 312 pushes the O-ring to the drop groove, a part of the O-ring will enter the drop groove first. As the second pushing device 312 pushes the O-ring, the O-ring at the drop groove will tilt, and the O-ring will not be properly mounted on the positioning post 35. After the telescopic plate 3211 is provided, the telescopic plate 3211 can support the O-ring moved to the drop groove. In this way, when the O-ring is pushed to the top of the drop groove by the second pushing device 312, the O-ring will not tilt due to the support of the telescopic plate 3211. When the second pushing device 312 completely pushes the O-ring to the top of the drop groove, the fourth linear drive 3212 drives the telescopic plate 3211 to slide out of the drop groove, so that the O-ring can directly fall on the positioning post 35.

[0059] Reference Figure 1 and Figure 3: The positioning and conveying device 3 includes an identification device 39, and the identification device 39 includes a bracket 391 and a camera 392; the bracket 391 is fixedly arranged above the vibration plate 2; the camera 392 is fixedly arranged on the upper part of the bracket 391, and the output end of the camera 392 is vertically downward. A controller is provided on the base 1, and the camera 392 controls the operation of the vibration plate 2 through the controller.

[0060] After the camera 392 detects that an O-ring has fallen onto the working platform 32 , the camera 392 stops the vibration plate 2 through the controller.

[0061] Reference Figure 2 and Figure 3 : The moving device 38 includes a slide 381 and a slider 382; the slide 381 is horizontally arranged below the lifting device 33; the slider 382 is slidably arranged on the slide 381 along the length direction of the slide 381, and the slider 382 is fixedly connected to the lower portion of the lifting device 33.

[0062] When the O-ring falls on the positioning post 35 , the slider 382 will slide on the slide 381 , so that the manipulator holding the solenoid valve can be assembled with the O-ring sleeved on the positioning post 35 .

[0063] Reference Figures 1-10 The present invention also includes an automatic assembly process for an electromagnetic valve O-ring, the specific steps of which are as follows:

[0064] S1: The first linear drive 34 is in a semi-extended state, the lifting device 33 is in an extended state, the vibrating plate 2 transports the O-ring to the working platform 32, and the positioning device 31 positions the O-ring in the drop groove;

[0065] S2: The O-ring falls from the drop chute onto the positioning post 35, the lifting device 33 retracts, and the unfolding device 36 starts to unfold the O-ring;

[0066] S3. The manipulator aligns the solenoid valve to be installed with the positioning column 35. The O-ring contacts the pushing device 37 driven by the unfolding device 36. The pushing device 37 and the first linear drive 34 are started synchronously. The pushing device 37 drives the O-ring to roll on the unfolding device 36. The first linear drive 34 drives the positioning column 35 to descend, and finally the O-ring is placed on the solenoid valve to be installed.

[0067] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
