[0025] To better achieve the objectives of this invention, this invention also provides a method for assembling a valve core with a sealing function, comprising the following steps:

[0026] Step 1: The direct vibrating feeder feeds the valve core into the slot of the semi-circular groove receiving plate. The valve core is supported above the slot by the central ring. The first cylinder drives the L-shaped plate to move to the left, causing the semi-circular groove receiving plate to move the valve core to the set position. At the same time, the side wall of the semi-circular groove receiving plate blocks the valve core to be processed in the direct vibrating feeder.

[0027] Step 2: After the rotary table moves the valve core to the set position, the third cylinder moves the thumb cylinder to the set position through the slide plate. The second cylinder moves the thumb cylinder vertically downward to clamp the valve core. Then the thumb cylinder resets and moves the valve core into the standard hole on the rotary table.

[0028] Step 3: When the rotary table moves the valve core to align it with the top pin, the fourth cylinder moves the funnel groove receiving plate through the slider, causing the funnel groove receiving plate to move the rubber ring to directly above the valve core. The punching cylinder then pushes the pin downwards. The pin passes through the conical opening, pushes open the sliding block, and presses the rubber ring from the conical opening into the opening at the top of the valve core. Then the pin resets. After the pin disengages from the semi-circular groove receiving plate, the sliding block is pulled back to its original position by the spring, and then the funnel groove receiving plate resets.

[0029] Step 4: When the rotary table moves the valve core to align it with the pressure rod, the drive structure drives the rotating plate to rotate, and the rotating plate drives the pressure rod to move. The bottom of the pressure rod presses down on the valve core to close the valve core opening, and then the pressure rod returns to its original position.

[0030] Step 5: When the rotary table moves the valve core to align it with the thumb cylinder of the switching component, the thumb cylinder of the discharge switching component will move the valve core from the standard hole of the rotary table to the top of the discharge plate and release it. Then the thumb cylinder of the switching component will reset, and the valve core will fall into the collection box through the discharge plate, completing the valve core assembly operation.

[0031] The present invention has the following technical effects:

[0032] 1. In this invention, the valve core moves to the processing station via the valve core feeding assembly, and is then moved to the standard hole and inserted into it via the feeding switching assembly. Subsequently, the rotary table rotates, driving the valve core to the processing position of the assembly mechanism. The assembly mechanism assembles the rubber ring with the valve core. Then, the rotary table drives the valve core to the processing position of the closing assembly. The closing assembly squeezes and closes the opening at the top of the valve core. Finally, the valve core moves to the processing position of the discharge switching assembly, where it is detached from the rotary table and moved to the discharge plate to fall, thus achieving collection. This device achieves fully automated and precise operation, occupies a small volume, has a simple structure, high accuracy, and is easy to maintain. Attached Figure Description

[0049] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0050] Example 1

[0051] Please refer to the instruction manual appendix. Figure 1-11 A valve core assembly device with sealing function includes a control cabinet 1 and a rotary table 31 rotatably mounted on the top of the control cabinet 1. A valve core feeding assembly 2 for controlling valve core feeding is provided on the top right side of the control cabinet 1.

[0052] A processing conversion plate 3 is fixedly installed on the top of the control cabinet 1. The processing conversion plate 3 is rotatably connected to the rotary table 31. Multiple standard holes 32 for placing valve cores are opened on the outer edge of the rotary table 31. The standard holes 32 are evenly distributed in a circular array with equal spacing.

[0053] The top front side of the processing conversion plate 3 is provided with a feed shifting component 4 for moving the valve core to the processing standard position;

[0054] The top left side of the processing conversion plate 3 is provided with a combination mechanism 5 for assembling the valve core and the rubber ring. The combination mechanism 5 includes a rubber ring feeding assembly 51, a punching assembly 54, a pushing assembly 52 for pushing the rubber ring into the valve core, and a micro-expansion assembly 53. The rubber ring feeding assembly 51 is fixedly installed on the top left side of the control cabinet 1. The pushing assembly 52 is located on the top left side of the control cabinet 1 and is located behind the rubber ring feeding assembly 51. The micro-expansion assembly 53 is located on the pushing assembly 52. ​​The punching assembly 54 is located on the top left side of the processing conversion plate 3.

[0055] A sealing assembly 6 for sealing the valve core is provided on the top left side of the control cabinet 1, and a discharge switching assembly 7 for moving the valve core out of the processing standard position is provided on the top rear side of the processing conversion plate 3. A discharge plate 8 for collecting the processed finished products is fixedly connected to the top rear side of the control cabinet 1.

[0056] In use, the valve core moves to the processing station via the valve core feeding assembly 2, and is then moved to the standard hole 32 and inserted into it via the feeding switching assembly 4. The rotary table 31 then rotates, moving the valve core to the processing position of the assembly mechanism 5. The assembly mechanism 5 assembles the rubber ring with the valve core. The rotary table 31 then moves the valve core to the processing position of the closing assembly 6, which closes the opening at the top of the valve core. Finally, the valve core moves to the processing position of the discharge switching assembly 7, which detaches the valve core from the rotary table 31 and moves it to the discharge plate 8 for collection. This device achieves fully automated operation, reducing labor intensity. It has a simple structure, high precision, and is easy to maintain.

[0057] Example 2

[0058] like Figure 1-11 As shown, in a preferred embodiment of the present invention, the valve core feeding assembly 2 includes a direct vibration feeder 21 and a limit offset assembly 22. The direct vibration feeder 21 is connected to the discharge port of an external vibrating plate. The direct vibration feeder 21 is located on the top front side of the control cabinet 1. The limit offset assembly 22 is located on the top right side of the control cabinet 1. The ends of the direct vibration feeder 21 and the limit offset assembly 22 are in sliding contact.

[0059] The limiting offset assembly 22 includes a first cylinder 221, an L-shaped plate 222, and a semi-circular groove receiving plate 223. The first cylinder 221 is fixedly connected to the top right side of the control cabinet 1. The L-shaped plate 222 is slidably connected to the top of the first cylinder 221. The inner wall of the left end of the L-shaped plate 222 is fixedly connected to the output end of the first cylinder 221. The semi-circular groove receiving plate 223 is fixedly connected to the top of the L-shaped plate 222. The left end of the semi-circular groove receiving plate 223 is in sliding contact with the rear end of the direct vibration feeder 21.

[0060] When the valve core enters from the linear vibrating feeder 21, the valve cores will be arranged in a straight line. In the natural state, the semi-circular groove of the semi-circular groove receiving plate 223 is aligned with the valve core. The valve core at the front will enter the groove and be supported above the groove by the ring in the middle of the valve core. During processing, the first cylinder 221 is started to drive the L-shaped plate 222 to move to the left. The semi-circular groove receiving plate 223 drives the valve core to move to the standard position. At this time, the front side of the outer wall of the semi-circular groove receiving plate 223 is attached to the rear end of the linear vibrating feeder 21 to prevent the valve cores arranged behind from falling off. When the semi-circular groove receiving plate 223 is reset, the next valve core moves into the semi-circular groove to realize the cycle.

[0061] The feeding and shifting assembly 4 includes a feeding clamping assembly 41 for clamping the valve core, a lifting structure 42 for controlling the lifting of the feeding clamping assembly 41, and a translation assembly 43 for controlling the movement of the lifting structure 42. The translation assembly 43 is fixedly installed on the top of the processing conversion plate 3. The lifting structure 42 is movably connected to the translation assembly 43. The feeding clamping assembly 41 is movably connected to the lifting structure 42. The translation assembly 43 includes a support plate 431, a third cylinder 432, and a sliding plate 433. The support plate 431 is fixedly connected to the top of the processing conversion plate 3. The third cylinder 432 is fixedly connected to the front side of the support plate 431. The sliding plate 433 is limited and slidably connected to the front side of the support plate 431.

[0062] The lifting structure 42 includes a second cylinder 421, which is fixedly connected to the upper front part of the slide plate 433.

[0063] The feeding clamping assembly 41 includes a thumb cylinder 411 and a slide rail 412. The slide rail 412 is fixedly connected to the lower middle part of the front side of the slide plate 433. The thumb cylinder 411 is slidably connected to the slide rail 412. The top of the thumb cylinder 411 is fixedly connected to the output end of the second cylinder 421.

[0064] After the valve core moves to the standard position, the third cylinder 432 will push the slide plate 433 to move to the designated position. Then the second cylinder 421 will push the thumb cylinder 411 to descend. After the thumb cylinder 411 descends to the designated position, it will clamp the valve core. Then the above steps will be reversed so that the valve core is pulled out of the semi-circular groove receiving plate 223, rises and moves to the standard hole 32 on the rotary table 31, completing one cycle. Repeating this step can standardize the movement of the valve core into the processing position.

[0065] The rubber ring feeding assembly 51 includes a feeding pipe 511 and a feeding groove 512. The feeding pipe 511 is fixedly connected to the top of the control cabinet 1, and the feeding groove 512 is opened on the feeding pipe 511.

[0066] The pushing assembly 52 includes a fourth cylinder 521, a slider 522, and a funnel groove receiving plate 523. The fourth cylinder 521 is fixedly connected to the top of the control cabinet 1. The slider 522 slides at the top of the control cabinet 1. The funnel groove receiving plate 523 is fixedly connected to the top of the slider 522. A limit post is fixed to the top of the control cabinet 1. Flanges are provided on the left and right sides of the top of the funnel groove receiving plate 523.

[0067] The micro-expansion component 53 includes a sliding block 531 and a spring 532. The sliding block 531 is slidably connected to the bottom of the funnel groove receiving plate 523. The right end of the funnel groove receiving plate 523 is divided into two parts. The left part is fixed to the funnel groove receiving plate 523, and the right part is fixed to the top of the sliding block 531. The two parts are spliced ​​together to form an inverted cone-shaped groove.

[0068] The punching assembly 54 includes a punching cylinder 541 and an ejector pin 542. The punching cylinder 541 is fixedly connected to the top front side of the processing conversion plate 3, and the ejector pin 542 is fixedly connected to the output end of the punching cylinder 541.

[0069] When the valve core moves to the processing position of the assembly mechanism 5, the rubber ring will enter the conical opening of the funnel groove receiving plate 523 from the feed groove 512. During the movement of the funnel groove receiving plate 523, the flange will contact the limiting post, thereby limiting the movement range of the funnel groove receiving plate 523. The fourth cylinder 521 pushes the slider 522 to move, thereby moving the funnel groove receiving plate 523. The funnel groove receiving plate 523 drives the rubber ring to enter directly above the valve core. At this time, the control of the punching cylinder 541 causes the ejector pin 542 to push downward, pressing the rubber ring from the conical opening into the opening at the top of the valve core, realizing automated standard assembly. During this process, when the ejector pin 542 passes through the conical opening, the sliding block 531 will move slightly to the right, and then be pulled back to its original position by the spring 532, thereby preventing the ejector pin 542 from being stuck during the ejection process.

[0070] The closing assembly 6 includes a drive structure 61, a support platform 62, a rotating plate 63, and a pressure rod 64. The support platform 62 is fixedly connected to the top left side of the control cabinet 1. The rotating plate 63 is rotatably connected to the top of the support platform 62. The pressure rod 64 is slidably connected to the right end of the support platform 62 and is limited in its position. The pressure rod 64 is rotatably connected to the right end of the rotating plate 63. The drive structure 61 drives the rotating plate 63 to rotate. The bottom of the pressure rod 64 is provided with a pressing groove, which contacts the top of the valve core. A spring is fixedly connected between the bottom right end of the rotating plate 63 and the top right end of the support platform 62. The spring is sleeved on the outer wall of the pressure rod 64.

[0071] The drive structure 61 is configured as a hydraulic cylinder, and the output end of the hydraulic cylinder is slidably connected to the bottom left end of the rotating plate 63.

[0072] When the valve core moves to the processing position of the closing assembly 6, the drive structure 61 drives the rotating plate 63 to rotate. During the rotation, the bottom left end of 63 slides against the output end of the hydraulic cylinder. The rotating plate 63 drives the pressure rod 64 to move, and the bottom of the pressure rod 64 presses the valve core to close the valve core opening.

[0073] The structure of the discharge transposition component 7 is the same as that of the feed transposition component 4, and the installation angle of the discharge transposition component 7 is perpendicular to that of the feed transposition component 4.

[0074] When the valve core moves to the discharge switching component 7, the discharge switching component 7 will remove the valve core from the standard hole 32 of the rotary table 31, and then move it above the discharge plate 8 to release it. The valve core falls into the collection box through the discharge plate 8 to complete the processing. The operation process is fully automated, reducing labor intensity.

[0075] Example 3

[0076] like Figure 1-11 As shown, in order to better achieve the purpose of the present invention, the present invention also provides a method for assembling a valve core with a sealing function, comprising the following steps:

[0077] Step 1: The direct vibrating feeder 21 feeds the valve core into the groove of the semi-circular groove receiving plate 223. The valve core is supported above the groove by the central ring. The first cylinder 221 drives the L-shaped plate 222 to move to the left, causing the semi-circular groove receiving plate 223 to move the valve core to the set position. At the same time, the side wall of the semi-circular groove receiving plate 223 blocks the valve core to be processed in the direct vibrating feeder 21.

[0078] Step 2: After the rotary table 31 moves the valve core to the set position, the third cylinder 432 moves the thumb cylinder 411 to the set position through the slide plate 433. The second cylinder 421 moves the thumb cylinder 411 vertically downward to clamp the valve core. Then the thumb cylinder 411 resets and moves the valve core into the standard hole 32 on the rotary table 31.

[0079] Step 3: When the rotary table 31 moves the valve core to align it with the ejector pin 542, the fourth cylinder 521 moves the funnel groove receiving plate 523 through the slider 522, causing the funnel groove receiving plate 523 to move the rubber ring to directly above the valve core. The punching cylinder 541 pushes the ejector pin 542 downward. The ejector pin 542 passes through the conical opening and pushes open the sliding block 531, pressing the rubber ring from the conical opening into the opening at the top of the valve core. Then the ejector pin 542 resets. After the ejector pin 542 disengages from the semi-circular groove receiving plate 223, the sliding block 531 is pulled back to its original position by the spring 532, and then the funnel groove receiving plate 523 resets.

[0080] Step 4: When the rotary table 31 moves the valve core to align it with the pressure rod 64, the drive structure 61 drives the rotating plate 63 to rotate, the rotating plate 63 drives the pressure rod 64 to move, and the bottom of the pressure rod 64 presses the valve core to close the valve core opening. Then the pressure rod 64 returns to its original position.

[0081] Step 5: When the rotary table 31 moves the valve core to align it with the thumb cylinder 411 of the switching assembly 7, the thumb cylinder 411 of the discharge switching assembly 7 will move the valve core from the standard hole 32 of the rotary table 31 to the top of the discharge plate 8 and release it. Then the thumb cylinder 411 of the switching assembly 7 will reset, and the valve core will fall into the collection box through the discharge plate 8, completing the valve core assembly operation.

[0082] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.

7. A method for assembling a valve core with a sealing function as described in claim 6, characterized in that, Includes the following steps: Step 1: The direct vibrating feeder (21) feeds the valve core into the slot of the semi-circular groove receiving plate (223). The valve core is supported above the slot by the central ring. The first cylinder (221) drives the L-shaped plate (222) to move to the left, causing the semi-circular groove receiving plate (223) to move the valve core to the set position. At the same time, the side wall of the semi-circular groove receiving plate (223) blocks the valve core to be processed in the direct vibrating feeder (21). Step 2: After the rotary table (31) moves the valve core to the set position, the third cylinder (432) moves the thumb cylinder (411) to the set position through the slide plate (433), and the second cylinder (421) moves the thumb cylinder (411) vertically downward to clamp the valve core. Then the thumb cylinder (411) resets and moves the valve core into the standard hole (32) on the rotary table (31). Step 3: When the rotary table (31) moves the valve core to align it with the ejector pin (542), the fourth cylinder (521) moves the funnel groove receiving plate (523) through the slider (522), causing the funnel groove receiving plate (523) to move the rubber ring to the top of the valve core. The punching cylinder (541) pushes the ejector pin (542) downward. The ejector pin (542) passes through the conical opening and pushes open the sliding block (531) to press the rubber ring from the conical opening into the opening at the top of the valve core. Then the ejector pin (542) resets. After the ejector pin (542) disengages from the semi-circular groove receiving plate (223), the sliding block (531) is pulled back to its original position by the spring (532). Then the funnel groove receiving plate (523) resets. Step 4: When the rotary table (31) moves the valve core to align with the pressure rod (64), the drive structure (61) drives the rotating plate (63) to rotate, the rotating plate (63) drives the pressure rod (64) to move, the bottom of the pressure rod (64) presses the valve core to close the valve core opening, and then the pressure rod (64) resets. Step 5: When the rotary table (31) moves the valve core to align with the thumb cylinder (411) of the switching assembly (7), the thumb cylinder (411) of the discharge switching assembly (7) will move the valve core from the standard hole (32) of the rotary table (31) to the top of the discharge plate (8) and release it. Then the thumb cylinder (411) of the switching assembly (7) will reset, and the valve core will fall into the collection box through the discharge plate (8) to complete the valve core assembly operation.
