[0023] The second transfer mechanism includes a second transfer cylinder and a second sliding seat connected to the second transfer cylinder. The second sliding seat has a slot that matches the output port of the second transmission component. When the second transfer cylinder drives the second sliding seat to move onto the second transmission component, the adjusting pin on the second transmission component is transferred to the slot of the second sliding seat.

[0048] like Figures 1-18 As shown, a stove valve fine-tuning pin assembly assembly device is provided.

[0049] Includes rack 1;

[0050] Rotary disk 2 is rotatably mounted on frame 1. The rotating disk 2 is provided with multiple positioning fixtures 5 for placing adjusting nails 3 and auxiliary fixture devices 6 for placing sealing rings 4.

[0051] The frame 1 is arranged around the rotating disk 2 in the following order: a first feeding device for placing the sealing ring 4 on the auxiliary fixture device 6; b a first detection device for detecting whether the sealing ring 4 is installed in place on the auxiliary fixture device 6; c a second feeding device for placing the adjusting pin 3 on the positioning fixture 5; d an assembly device for fitting the sealing ring 4 on the auxiliary fixture device 6 onto the adjusting pin 3 on the positioning fixture 5; e a second detection device for detecting whether the sealing ring 4 is installed in place on the adjusting pin 3; and f a finished product unloading device for removing the finished adjusting pin 3.

[0052] Specifically, in the above assembly process, the sealing ring 4 can be fitted onto the adjusting pin 3 to form the finished adjusting pin 3 through the first feeding device a, the second feeding device c, and the assembly device d. The finished adjusting pin 3 is then removed from the warehouse by the finished product unloading device f. Furthermore, under the action of the first detection device b and the second detection device e, it can be checked whether the sealing ring 4 is properly installed on the auxiliary fixture device 6 and whether the sealing ring 4 is properly installed on the adjusting pin 3. This changes the traditional manual operation, improves production efficiency, reduces labor costs, meets the production requirements of existing processes, and significantly improves economic benefits. Since the product processing is automated and has strict processing standards, the impact of human factors on quality during production is reduced, thereby reducing the problem of improper installation of the sealing ring 4 during assembly and improving product quality.

[0053] Furthermore, such as Figure 17 As shown, the auxiliary fixture device 6 includes an auxiliary fixture 601 and a lifting structure 602 that can be raised and lowered relative to the auxiliary fixture 601. The auxiliary fixture 601 is provided with a fixing part 6011 for cooperating with the sealing ring 4. The lifting structure 602 includes a movable block 6021, a movable column 6022, a spring 6023 and a positioning plate 6024. One end of the movable column 6022 is connected to the movable block 6021, and the other end of the movable column 6022 is connected to the positioning plate 6024. The spring 6023 is sleeved on the movable column 6022. The fixing part 6011 is provided with a fixing column 6011h that extends upward. The fixing part 6011 is installed on the auxiliary fixture 601, and the fixing column 6011h protrudes from the positioning plate 6024.

[0054] like Figure 3 As shown, the first feeding device includes a first vibratory plate a1, a first transmission component a2, a first transfer mechanism a3 and a first pick-and-place mechanism a4. The first vibratory plate a1 is used to transfer the sealing ring 4 to the first transfer mechanism a3. The sealing ring 4 on the first transfer mechanism a3 is placed on the auxiliary fixture 601 through the first pick-and-place mechanism a4 and cooperates with the fixed column 6011h.

[0055] like Figure 5 As shown, the first transfer mechanism a3 includes a first transfer cylinder a31 and a first sliding seat a32 connected to the first transfer cylinder a31. The first sliding seat a32 is provided with a first sliding groove a321 that matches the output port of the first transmission component a2. The first sliding seat a32 is provided with a positioning component a322 for positioning the sealing ring 4. The positioning component a322 includes a positioning cylinder a3221 and a positioning piece a3222 connected to the positioning cylinder a3221. The positioning piece a3222 can slide on the positioning cylinder a3221. When the first transfer cylinder a31 drives the first sliding seat a32 to move onto the first transmission component a2, the positioning piece a3222 can slide into the first slide groove a321 via the positioning cylinder a3221. When the sealing ring 4 on the first transmission component a2 is transferred to the first slide groove a321 of the first sliding seat a322, the end of the positioning piece a3222 abuts against the outer periphery of the sealing ring 4. When the first sliding seat a32 moves away from the first transmission component a2, the first pick-and-place mechanism a4 clamps the sealing ring 4 on the first sliding seat a32.

[0056] like Figure 4 As shown, the first pick-and-place mechanism a4 includes a first support frame a41, a first pushing component a42, a first lifting component a43, and a first clamping component a44. The first lifting component a43 is mounted on the first pushing component a42, and the first clamping component a44 is mounted on the first lifting component a43. The first clamping component a44 can be lifted up and down through the first lifting component a43, and the first clamping component a44 can move on the first sliding seat a32 or the auxiliary fixture 601 through the first pushing component a42.

[0057] like Figure 4 As shown, the first clamping assembly a44 includes a first fixed base a441, a first cylinder a442, a first drive shaft a443, and a bushing a444. The bushing a444 is fixedly mounted on the first fixed base a441. The first cylinder a442 is connected to the first drive shaft a443, and the first drive shaft a443 passes through the bushing a444 and at least partially protrudes from the bushing a444. The first drive shaft a443 rises or falls via the first cylinder a442.

[0058] When the first drive shaft a443 descends, the first drive shaft a443, carrying the sealing ring 4, contacts the fixed column 6011h. When the first drive shaft a443 rises and resets, the sealing ring 4 is pushed onto the fixed column 6011h by the bushing a444.

[0059] Specifically, when the first transfer cylinder a31 drives the first sliding seat a32 to move onto the first transmission component a2, the positioning piece a3222 can slide into the first groove a321 through the positioning cylinder a3221, so that the sealing ring 4 on the first transmission component a2 is transferred to the first groove a321 of the first sliding seat a32, and the end of the positioning piece a3222 abuts against the outer periphery of the sealing ring 4; when the first sliding seat a32 moves away from the first transmission component a2, the first pushing component a42 drives the first picking and placing mechanism a4 to move onto the first sliding seat a32, and the first clamping component a44 passes through the first... When the lifting component a43 descends, the first drive shaft a443 descends via the first cylinder a442, thereby enabling the first drive shaft a443 to engage with the inner diameter of the sealing ring 4. When the first pushing component a42 drives the first picking and placing mechanism a4 to move to the auxiliary fixture 601 on the first sliding seat a32, the first clamping component a44 descends via the first lifting component a43. At this time, the first drive shaft a443 rises via the first cylinder a442. When the first drive shaft a443 rises and resets, the sealing ring 4 is pushed onto the fixed column 6011h under the action of the bushing a444.

[0060] Furthermore, such as Figure 6 As shown, the first detection device b includes a second support frame b1, a first slide cylinder b2, and a first detector b3. The first slide cylinder b2 is installed on the second support frame b1, and the first detector b3 is installed on the first slide cylinder b2. The first detector b3 can be raised and lowered on the auxiliary fixture device 6 by the first slide cylinder b2 to detect whether the sealing ring 4 is installed in place on the fixed column 6011h.

[0061] Specifically, the first detector b3 is a CCD camera or a position sensor. When the rotating disk 2 causes the auxiliary fixture device 6 to rotate to the first detection device b, the first slide cylinder b2 extends outward, so that the first detector b3 detects whether the sealing ring 4 is installed in place on the fixed column 6011h.

[0062] Furthermore, such as Figure 7 As shown, the second feeding device c includes a second vibratory plate c1, a second transmission component c2, a second transfer mechanism c3, and a second pick-and-place mechanism c4. The second vibratory plate c1 is used to transfer the sealing ring 4 to the second transfer mechanism c3. The positioning fixture 5 is provided with a insertion hole 501 for inserting the adjusting pin 3. The adjusting pin 3 on the second transfer mechanism c3 is placed on the positioning fixture 5 through the second pick-and-place mechanism c4 and cooperates with the insertion hole 501.

[0063] like Figure 9 As shown, the second transfer mechanism c3 includes a second transfer cylinder c31 and a second sliding seat c32 connected to the second transfer cylinder c31. The second sliding seat c32 is provided with a slot c321 that matches the output port of the second transmission component c2. When the second transfer cylinder c31 drives the second sliding seat c32 to move onto the second transmission component c2, the adjusting pin 3 on the second transmission component c2 is transferred to the slot c321 of the second sliding seat c32. When the second sliding seat c32 moves away from the second transmission component c2, the second pick-and-place mechanism c4 clamps the adjusting pin 3 on the second sliding seat c32.

[0064] like Figure 8 As shown, the second pick-and-place mechanism c4 includes a third support frame c41, a second pushing component c42, a second slide cylinder c43, and a second clamping component c44. The second pushing component c42 is mounted on the third support frame c41 and connected to the second slide cylinder c43. The second clamping component c44 is mounted on the second slide cylinder c43 and can be raised and lowered by the second slide cylinder c43. The second clamping component c44 can move on the second sliding seat c32 or the positioning fixture 5 by the second pushing component c42.

[0065] Furthermore, such as Figure 8 As shown, the second clamping assembly c44 includes a first clamping drive member c441 and a plurality of first grippers c442. The plurality of first grippers c442 are evenly arranged circumferentially around the first clamping drive member c441. The plurality of first grippers c442 can be expanded or closed by the first clamping drive member c441. When the second clamping assembly c444 moves on the second sliding seat c32, the plurality of first grippers c442 are expanded by the first clamping drive member c441 and clamp the adjusting pin 3 on the second sliding seat c32. When the second clamping assembly c44 moves on the positioning fixture 5, the second clamping assembly c444 is lowered to the positioning fixture 5 by the second slide cylinder c43, thereby causing the adjusting pin 3 to be inserted into the insertion hole 501 of the positioning fixture 5.

[0066] Furthermore, such as Figures 10-12 As shown, the assembly device d includes a fourth support frame d1, a third pushing component d2, a third slide cylinder d3, a third clamping component d4, and a third lifting component d5. The third pushing component d2 is mounted on the fourth support frame d1 and connected to the third slide cylinder d3. The third clamping component d4 is mounted on the third slide cylinder d3. The third lifting component d5 is mounted on the third clamping component d4. The third clamping component d4 can be raised and lowered by the third slide cylinder d3. The third clamping component d4 can move on the positioning fixture 5 or the auxiliary fixture 601 by the third pushing component d2.

[0067] The third lifting assembly d5 includes a third lifting cylinder d51 and a lever d52 connected to the third lifting cylinder d51. The lever d52 can be raised and lowered via the third lifting cylinder d51.

[0068] Furthermore, such as Figures 10-12 As shown, the third clamping assembly d4 includes a second clamping drive member d41 and a plurality of second grippers d42. The plurality of second grippers d42 are evenly arranged circumferentially around the second clamping drive member d41. The plurality of second grippers d42 can be opened or closed through the second clamping drive member d41. The lever d52 is provided with an opening d521 for the second grippers d42 to pass through.

[0069] like Figures 10-12 As shown, the assembly device d also includes a first lifting cylinder d6 connected to the lifting structure 602. The output end of the first lifting cylinder d6 is connected to the movable block 6021. When the third clamping component d4 moves onto the auxiliary fixture 601, the third clamping component d4 descends through the third slide cylinder d3 and passes through the opening d521, so that the end of the second gripper d42 contacts the end of the fixed column 6011h. The movable block 6021 is lifted upward by the first lifting cylinder d6, so that the movable column 6022 lifts the positioning plate 6024 and compresses the spring 6023, thereby pushing the sealing ring 4 on the fixed column 6011h. The multiple second grippers d42 unfold through the second clamping drive d41 and clamp the sealing ring 4.

[0070] The second clamping drive component d41 clamps the sealing ring 4 and moves it to the positioning fixture 5 through the third pushing component d2, aligning it with the adjusting pin 3. The sealing ring 4 on the second gripper d42 is driven by the third lifting cylinder d51 to lower the paddle d52, so that the sealing ring 4 is fitted onto the stepped groove 330 of the adjusting pin 3.

[0071] Furthermore, such as Figure 13 As shown, the second detection device e includes a fifth support frame e1, a fourth slide cylinder e2, and a second detector e3. The fourth slide cylinder e2 is mounted on the fifth support frame e1, and the second detector e3 is mounted on the fourth slide cylinder e2. The second detector e3 can slide back and forth on the positioning fixture 5 through the fourth slide cylinder e2 to detect whether the sealing ring 4 is installed in place on the stepped groove 330 of the adjusting pin 3.

[0072] Furthermore, such as Figure 14 and Figure 15As shown, the finished product unloading device f includes a discharge tray f1, a gantry frame f2, and an unloading mechanism f3 that slides on the gantry frame f2. The unloading mechanism f3 can slide on the gantry frame f2 onto the discharge tray f1 or the positioning fixture 5. The unloading mechanism f3 includes a fifth slide cylinder f31 and a magnetic suction rod f32. The magnetic suction rod f32 can slide up and down on the discharge tray f1 or the positioning fixture 5 through the fifth slide cylinder f31. When the unloading mechanism f3 slides onto the positioning fixture 5, the magnetic suction rod f32 slides down through the fifth slide cylinder f31, causing the magnetic suction rod f32 to magnetically attract the finished product of the adjusting nail 3. When the unloading mechanism f3 slides onto the discharge tray f1, the magnetic suction rod f32 slides down through the fifth slide cylinder f31, causing the finished product of the adjusting nail 3 to be placed on the discharge tray f1.

[0073] Furthermore, such as Figure 16 As shown, the frame 1 is also equipped with a residue detection device g, which is used to remove residual workpieces on the positioning fixture 5 and the auxiliary fixture 601. The residue detection device g includes a waste recycling box g1, a third detector g3 for detecting whether there are residual workpieces on the positioning fixture 5, and a fourth detector g4 for detecting whether there are residual workpieces on the auxiliary fixture 601.
