[0062] like Figures 1-19 As shown, a stove valve transmission assembly assembly device is provided.

[0063] Includes rack 1;

[0064] Rotary disk 2 is rotatably mounted on frame 1. The rotating disk 2 is provided with a plurality of auxiliary fixtures 4 for placing transmission components 3.

[0065] The frame 1 is arranged around the rotating disk 2 in the following order: a first assembly device a for assembling the limiting piece 301 onto the auxiliary fixture 4; a second assembly device b for assembling the push plate 302 onto the auxiliary fixture 4, so that the push plate 302 is mounted on the limiting piece 301; a third assembly device c for assembling the retaining spring 303 onto the auxiliary fixture 4, so that one end of the retaining spring 303 abuts against the push plate 302; a fourth assembly device d for assembling the base plate 304 onto the auxiliary fixture 4; a fifth assembly device e for sequentially inserting the valve stem 305 into the auxiliary fixture 4 and cooperating with the base plate 304, retaining spring 303, push plate 302, and limiting piece 301; and a sixth assembly device f for inserting the E-type retaining spring 306 into the auxiliary fixture 4, so that the E-type retaining spring 306 is snapped onto the valve stem 305 to form the transmission assembly 3.

[0066] The auxiliary fixture 4 is equipped with a positioning device 401, which includes a positioning post 4011 and a driving component 4012 that is connected to the positioning post 4011. The driving component 4012 is mounted on the auxiliary fixture 4 and can drive the positioning post 4011 to move up and down on the auxiliary fixture 4. The limiting plate 301, push plate 302, snap ring 303, base plate 304 and valve stem 305 of the transmission assembly 3 cooperate with the positioning post 4011 to realize the position correction of the transmission assembly 3.

[0067] Specifically, in the above assembly process, the first assembly device a, the second assembly device b, the third assembly device c, the fourth assembly device d, the fifth assembly device e, and the sixth assembly device f can automatically transport and assemble the limiting plate 301, the push plate 302, the snap ring 303, the base plate 304, the valve stem 305, and the E-type snap ring 306 to form the transmission assembly 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 mechanically automated and has strict processing standards, the impact of human factors on quality during production is reduced, thereby reducing errors in the processing process and improving product quality.

[0068] The driving component 4012 can be a driving cylinder, a servo motor, a pneumatic motor, etc. In this application, the driving device 202 is a driving cylinder so that the positioning column 4011 can move up and down on the auxiliary fixture 4, thereby enabling the limiting plate 301, the push plate 302, the snap ring 303, the base plate 304 and the valve stem 305 to cooperate with the positioning column 4011 to achieve the position correction of the transmission component 3.

[0069] like Figure 2 and Figure 3 As shown, the first assembly device a includes a first vibratory feeder a1, a first transmission component a2, a first detection mechanism a3, and a first pick-and-place mechanism a4. The first vibratory feeder a1 is used to supply the limiting piece 301. The first transmission component a2 is used to transmit the limiting piece 301 discharged from the outlet of the first vibratory feeder a1 to the first detection mechanism a3. The first detection mechanism a3 can detect the placement position of the limiting piece 301 and can adjust the limiting piece 301 to a position that cooperates with the positioning post 4011. The limiting piece 301 on the first detection mechanism a3 is placed on the auxiliary fixture 4 through the first pick-and-place mechanism a4 and cooperates with the positioning post 4011.

[0070] like Figure 2 and Figure 3 As shown, the first detection mechanism a3 includes a first transfer component a31, a first position detection component a32, a correction component a33, and a first lifting component a34;

[0071] like Figure 2 and Figure 3 As shown, the correction component a33 includes a correction motor a331 and a transmission shaft a332 connected to the correction motor a331; the first lifting component a34 includes a lifting cylinder a341 and a sliding component a342 that cooperates with the lifting cylinder a341, and the correction component a33 is mounted on the sliding component a342.

[0072] Specifically, the sliding component a342 consists of a slide rail and a slider. The conveying end of the lifting cylinder a341 is connected to the transmission shaft a332. When the lifting cylinder a341 rises, the correction motor a331 can slide up and down along the slide rail via the slider.

[0073] like Figure 2 and Figure 3 As shown, the first transfer component a31 includes a first transfer cylinder a311 and a first sliding seat a312 connected to the first transfer cylinder a311. The first sliding seat a312 is provided with a first positioning slot a3121 that matches the output port of the first transfer component a2.

[0074] like Figure 2 and Figure 3As shown, the first pick-and-place mechanism a4 includes a first support frame a41, a first lifting component a42, a first clamping component a43, and a first pushing component a44. The first pushing component a44 is mounted on the first support frame a41, the first lifting component a42 is mounted on the first pushing component a44, and the first clamping component a43 is mounted on the first lifting component a42. The first clamping component a43 can be lifted up and down through the first lifting component a42, and the first clamping component a43 can move on the first sliding seat a312 and the auxiliary fixture 4 through the first pushing component a44.

[0075] like Figure 2 and Figure 3 As shown, the first support frame a41 is provided with a waste recycling assembly a45 that cooperates with the first lifting assembly a42. The waste recycling assembly a45 includes a recycling cylinder a451 and a waste recycling box a452 connected to the recycling cylinder a451.

[0076] When the first transfer cylinder a311 drives the first sliding seat a312 to move onto the first transmission component a2, the limiting piece 301 on the first transmission component a2 is transferred to the first positioning slot a3121 on the first sliding seat a312. When the first transfer cylinder a311 drives the first sliding seat a312 to move to the position of the correction component a33, the transmission shaft a332 can move up and down on the first positioning slot a3121 via the first lifting component a34. The first position detection component a32 can detect the placement position of the D-axis hole 3011 and the groove 3012 of the limiting piece 301. The first position detection component a32 is electrically connected to the correction motor a331. When the groove 3012 of the limiting piece 301 is not positioned correctly, the correction motor a331 drives the transmission shaft a332 to rotate, causing... The drive shaft a332 drives the limiting plate 301 to rotate, so that the groove 3012 of the limiting plate 301 is correctly positioned. When the D-axis hole 3011 of the limiting plate 301 is not positioned correctly, the first lifting component a34 drives the drive shaft a332 to lift the limiting plate 301, and the recycling cylinder a451 pushes the recycling waste box a452 to extend towards the first positioning slot a3121. The first pick-and-place mechanism a4 clamps the limiting plate 301 and places it on the recycling waste box a452. When the D-axis hole 3011 and the groove 3012 of the limiting plate 301 are correctly positioned, the drive shaft a332 lifts the limiting plate 301 through the first lifting component a34, and the first pick-and-place mechanism a4 clamps the limiting plate 301 and moves it to the auxiliary fixture 4, so that the D-axis hole 3011 of the limiting plate 301 engages with the positioning post 4011.

[0077] Specifically, when the first vibratory feeder a1 conveys the limiting piece 301, the D-axis hole 3011 of the limiting piece 301 may be reversed. Therefore, when the first detection mechanism a3 detects that the D-axis hole 3011 of the limiting piece 301 is reversed, it sends a signal to the first pick-and-place mechanism a4. The first pick-and-place mechanism a4 clamps the limiting piece 301 with the reversed D-axis hole 3011 onto the recycling waste box a452. When the first detection mechanism a3 detects that the groove 3012 of the limiting piece 301 is incorrectly placed, it sends a signal to the correction motor a331. The correction motor a331 can rotate forward or reverse to drive the transmission shaft a332 to rotate, so as to adjust the placement position of the groove 3012 of the limiting piece 301.

[0078] It should be noted that the first detection mechanism a3 includes a drive cylinder and a CCD camera or position sensor mounted on the drive cylinder. When the first sliding seat a312 moves to the position of the correction component a33, the drive cylinder extends outward, so that the CCD camera or position sensor detects the placement position of the groove 3012 and the D-axis hole 3011 of the limiting sheet 301.

[0079] The first lifting component a42 is a lifting air rod.

[0080] Furthermore, such as Figure 4 and Figure 5 As shown, the second assembly device b includes a second vibratory plate b1, a second transmission component b2, a second transfer component b3, and a second pick-and-place mechanism b4. The second vibratory plate b1 is used to supply the push plate 302. The second transmission component b2 is used to transfer the push plate 302 discharged from the outlet of the second vibratory plate b1 to the second transfer component b3. The push plate 302 on the second transfer component b3 is placed on the auxiliary fixture 4 through the second pick-and-place mechanism b4 and cooperates with the positioning column 4011.

[0081] like Figure 4 and Figure 5 As shown, the second transfer component b3 includes a second transfer cylinder b31 and a second sliding seat b32 connected to the second transfer cylinder b31. The second sliding seat b32 is provided with a second positioning slot b321 that matches the output port of the second transmission component b2.
