[0003] The existing automobile steering wheel assembly equipment cannot carry and assemble the circuit frame due to its complex structure, resulting in the need for workers to assemble the button frame and the circuit frame at a dedicated workstation. However, the reliability of manual assembly is low, and improper assembly may cause the terminals between the button frame and the circuit frame to not be clamped. If the above situation occurs, qualified button frames will be screened out in the subsequent inspection process, causing economic losses. Moreover, manual assembly can only perform a single action at the same time. According to the assembly sequence of the automobile steering wheel, manual assembly must first assemble the button frame and the circuit frame, then inspect and screen them, and finally assemble the assembled and inspected button frame and circuit frame onto the steering wheel.

[0039] A positioning groove 22 for fixing the key frame 18 is provided on the surface of the push jig 17, a support plate 23 and a detection socket 24 are provided on the surface of the push jig 17 corresponding to the line frame 4, a push groove 25 is provided in the positioning groove 22, a main push plate 26 for pushing out the push jig 17 is fixedly connected to the back of the push jig 17, and the bottom of the main push plate 26 is fixedly connected to the output end of the assembly push cylinder 20, and the push jig 17 clamps the key frame 18 through the positioning groove 22 to prevent the key frame 18 from falling off when the workstation is switched;

[0041] The transverse transport mechanism 2 is located above the conveyor belt 1 and the assembly mechanism, and is used to transport the line frame 4 from the surface of the conveyor belt 1 to the surface of the assembly mechanism. The side of the transverse transport mechanism 2 facing the output end of the conveyor belt 1 is fixedly connected with an assembly push cylinder 5, and the output end of the assembly push cylinder 5 is fixedly connected with a fixed plate 6 matching the line frame 4. A plurality of small rotating motors 7 are fixedly connected to the upper surface of the fixed plate 6 corresponding to the line frame 4. The output end of the small rotating motor 7 is rotatably connected with a rotating rod 8. The bottom of the rotating rod 8 passes through the fixed plate 6 and is fixedly connected with an elliptical rotating block 9. The bottom of the fixed plate 6 A plurality of fixed blocks 10 are fixedly connected to the elliptical rotating block 9, and slide rails 11 are fixedly connected to the opposite sides of the fixed blocks 10. Telescopic parts 12 are slidably connected to the slide rails 11, and the bottoms of the telescopic parts 12 on both sides of the corresponding line frame 4 are fixedly connected with a composite clamping assembly for clamping the line frame 4 and its input terminals, and the bottoms of the telescopic parts 12 on the output end side of the corresponding line frame 4 are fixedly connected with a secondary clamping assembly for clamping the output terminals in the line frame 4. The conveyor belt 1, the conveyor chain, and the transverse transport mechanism 2 are all prior arts and will not be described in detail here.

[0042] Furthermore, a plurality of strong springs 29 for providing clamping force are fixedly connected to the side of the telescopic member 12 facing the fixed block 10, and one end of the strong spring 29 away from the telescopic member 12 is fixedly connected to the fixed block 10. The telescopic member 12 is tightly attached to the elliptical rotating block 9 under the elastic force of the strong spring 29, and the elliptical rotating block 9 can be driven to rotate synchronously by the small rotating motor 7.

[0043] Further, the composite clamping assembly includes a main clamping jaw 30 for clamping the input terminal of the circuit frame 4, the top of the main clamping jaw 30 is fixedly connected to the bottom of the telescopic member 12, the spacing between the main clamping jaws 30 matches the length of the input terminal in the circuit frame 4, so that the input terminal of the circuit frame 4 can be stably clamped, the bottom of the main clamping jaw 30 is fixedly connected with an auxiliary clamping jaw 31 for clamping the circuit frame 4, the two opposite sides of the bottom of the auxiliary clamping jaw 31 are fixedly connected with an arc-shaped clamping plate 32 matching the circuit frame 4, and the circuit frame 4 is clamped by the arc-shaped clamping plate 32, the secondary clamping assembly includes a secondary clamping jaw 33 for clamping the output terminal of the circuit frame 4, the top of the secondary clamping jaw 33 is fixedly connected to the telescopic member 12, the spacing between the secondary clamping jaws 33 matches the length of the output terminal in the circuit frame 4, so that the output terminal of the circuit frame 4 can be stably clamped, and the two opposite sides of the bottom of the main clamping jaw 30 and the secondary clamping jaw 33 are fixedly connected with rubber pads for protecting the terminals to avoid damage to the terminals due to excessive clamping;

[0044] It should be noted that: Figure 4 and Figure 5 As shown, when the small rotary motor 7 drives the elliptical rotating block 9 to align the long axis and squeeze the telescopic member 12, the elliptical rotating block 9 squeezes the telescopic member 12 to slide along the slide rail 11, forming a Figure 5 As shown in the state for releasing the clamping, when the elliptical rotating block 9 is aligned with the telescopic member 12 at the minor axis, the telescopic member 12 is reset under the action of the strong spring 29, forming a state as shown in FIG. Figure 4 The state shown for clamping;

[0045] A further advantage of adopting the above method is that the composite clamping assembly can not only clamp the input terminal of the circuit frame 4 through the main clamping jaw 30, but also clamp the circuit frame 4 through the auxiliary clamping jaw 31. Under the joint action of the main clamping jaw 30, the auxiliary clamping jaw 31 and the secondary clamping jaw 33, the function of clamping the circuit frame 4 can be realized, and support is provided for assembling the circuit frame 4 by the assembling push cylinder 5.

[0046] Furthermore, a limiting sliding hole 34 matching the limiting rod 16 is provided on the surface of the pushing jig 17, and the inner diameter of the limiting sliding hole 34 matches the rod body of the limiting rod 16 and is smaller than the top of the limiting rod 16, so that the pushing jig 17 can slide along the limiting rod 16 through the limiting sliding hole 34, while preventing the pushing jig 17 from falling off. A mounting groove 35 is provided on the back of the pushing jig 17, and the pushing jig 17 is fixedly connected to the bottom of the support plate 23. The distance difference between the pushing jig 17 and the support plate 23 matches the shape of the steering wheel skeleton in the prior art. An arc-shaped fixing plate 36 is fixedly connected to the support plate 23 at the corresponding line frame 4, and the arc-shaped fixing plate 36 is perpendicular to the arc-shaped clamping plate 32 in the horizontal direction. The arc-shaped fixing plate 36 is perpendicular to the arc-shaped clamping plate 32 in the horizontal direction to stagger the arc-shaped clamping plate 32 in the composite clamping assembly, so that the line frame 4 can be retained on the support plate 23 when the auxiliary clamping jaw 31 is released. On the surface of the plate 23, the depth of the positioning groove 22 is greater than the height of the key frame 18 when it is fixed, which is used to support the work of the positioning pin 37. A plurality of positioning pins 37 for fixing the key frame 18 are installed in the positioning groove 22 corresponding to the key frame 18. The center of the main push plate 26 is fixedly connected with a sequential spring 38 matching the mounting groove 35. The end of the sequential spring 38 away from the main push plate 26 is fixedly connected with the closed end in the mounting groove 35. The two ends of the surface of the main push plate 26 are fixedly connected with secondary push plates 39 for pushing out the key frame 18. The working order of the main push plate 26 and the secondary push plate 39 during assembly is controlled by the sequential spring 38, so that the main push plate 26, under the action of the assembly push cylinder 20, first pushes the push fixture 17 to align the assembled key frame 18 and the line frame 4 with the steering wheel frame, and then pushes the secondary push plate 39 to push the key out of the positioning groove 22 and assemble it to the steering wheel frame.

[0047] It should be noted that: by assembling the push cylinder 20 to push the main push plate 26, the main push plate 26 pushes the push fixture 17 to slide along the limit rod 16 through the sequential spring 38 until Figure 8As shown, it is blocked by the limit rod 16, which is used to align the steering wheel frame. At this time, the main push plate 26 is pushed to squeeze the sequence spring 38 to make the secondary push plate 39 continue to move forward, and the unqualified circuit frame 4 and the qualified circuit frame 4 are pushed out through the secondary push plate 39;

[0048] A further advantage of adopting the above method is that the button frame 18 can be prevented from falling off by the positioning pin 37, the detection of the button frame 18 and the circuit frame 4 can be supported by the detection socket 24, the pushing jig 17 can be pushed by the assembly motor so that the pushing jig 17 can be aligned with the steering wheel frame, and unqualified accessories can be pushed out and qualified accessories can be assembled to the steering wheel frame through the secondary push plate 39.

[0049] Furthermore, a roller 40 for sliding on the surface of the pushing ring 28 is fixedly connected to the bottom of the pressing rod 27, and a plurality of protrusions 41 for pushing the pressing rod 27 are fixedly connected in sequence on the surface of the pushing ring 28 corresponding to the pressing rod 27;

[0050] A further advantage of adopting the above method is that during the rotation of the multi-station assembly roller 14, the pressing rod 27 can drive the pressing rod 27 to slide along the surface of the pushing ring 28. When the pressing rod 27 passes through the protrusion 41, it slides toward the key frame 18 under the action of the protrusion 41. The pressing rod 27 presses the function keys in the key frame 18 in turn, thereby cooperating with the detection socket 24 to detect the key frame 18 and the circuit frame 4.

[0051] When processing the steering wheel accessories of the present invention, a worker or an organization places the button frame 18 in the positioning groove 22 of the pushing jig 17 and positions it through the positioning pin 37, and conveys the line frame 4 fixed by the mold through the conveyor belt 1, and conveys the steering wheel skeleton through the conveyor chain and the steering wheel hanger 3;

[0052] During assembly, the fixed plate 6 is moved to the top of the conveyor belt 1 and aligned with the line frame 4 through the transverse transport mechanism 2, the assembly push cylinder 5 is extended to drive the fixed plate 6 to descend to a suitable position, and the small rotary motor 7 drives the rotary rod 8 and the elliptical rotary block 9 to rotate, so that the elliptical rotary block 9 changes from the state of the long axis aligned with the telescopic part 12 to the state of the short axis aligned with the telescopic part 12. In this process, the telescopic part 12 slides on the slide rail 11 under the action of the strong spring 29, driving the composite clamping assembly and the secondary clamping assembly to form a clamping state, clamping the input terminal of the line frame 4 through the main clamping jaw 30, and clamping the line frame 4 through the auxiliary clamping jaw 31. The output terminal of the circuit frame 4 is clamped by the secondary clamping claw 33, so as to realize the function of clamping the circuit frame 4 and its terminals at the same time. After the clamping is completed, the assembly push cylinder 5 is reset, and the fixed plate 6 is moved to the top of the pushing fixture 17 by the transverse conveying mechanism 2, so that the circuit frame 4 is conveyed to the top of the pallet 23, and the assembly push cylinder 5 is lowered again, and the input terminals on both sides of the circuit frame 4 are plugged with the output ends of the key frame 18, and the output terminals of the circuit frame 4 are plugged with the detection socket 24, so as to complete the assembly of the accessories. After the assembly is completed, the large rotating motor 21 drives the multi-station assembly roller 14 to rotate 120° to the next station;

[0053] During the rotation of the multi-station assembly drum 14, the pressing rod 27 is driven to slide along the surface of the pushing ring 28 through the roller 40. When the pressing rod 27 passes the protrusion 41, it slides toward the key frame 18 under the action of the protrusion 41, and the function keys in the key frame 18 are pressed in turn by the pressing rod 27, so as to cooperate with the detection socket 24 to detect the key frame 18 and the line frame 4. When the multi-station assembly drum 14 rotates 120°, this station enters the screening area, and the next station enters the processing area. If the detection is unqualified, the unqualified key frame 18 and the line frame 4 are pushed out to the collection area by the joint action of the assembly push cylinder 20 and the pushing fixture 17. If the detection is qualified, the assembly push cylinder 20 is on standby, and then the multi-station assembly drum 14 continues to rotate 120°, so that the station enters the assembly area, realizing the function of detecting and screening steering wheel accessories;

[0054] During assembly, the main push plate 26 is pushed by the assembly push cylinder 20, and the main push plate 26 pushes the push fixture 17 to slide along the limit rod 16 through the sequence spring 38 until the main push plate 26 is pushed by the sequence spring 38. Figure 8 As shown, it is blocked by the limit rod 16, and the button frame 18 and the circuit frame 4 are moved into the steering wheel frame by the pushing fixture 17. At this time, the main push plate 26 is continued to be pushed to squeeze the sequence spring 38 so that the secondary push plate 39 continues to move forward, and the button frame 18 is pushed by the secondary push plate 39 to make it leave the positioning pin 37 and engage with the steering wheel frame. Then the assembly push cylinder 20 is retracted to drive the pushing fixture 17 to reset and complete the assembly of the steering wheel accessories.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
