The nut assembly mechanism 5 and the nut detection mechanism 6 are respectively located above the frame 1. A component cover assembly mechanism 7 is provided on one side of the mechanism 6 to assemble the component cover onto the inspected component body. The component cover assembly mechanism 7 is located on one side of the working turntable 4 and is positioned above the frame 1. A superior and inferior product discharge mechanism 8 is provided on one side of the component cover assembly mechanism 7 to pick up and transfer the superior and inferior product components with the component cover assembled from the working turntable 4.

Through the control computer 2, the various mechanisms can cooperate to assemble the component body.

[0028] The working turntable 4 includes a rotating disc 11 mounted above the frame 1, with tooling plates 10 arranged horizontally around the disc 11. Each tooling plate 10 has a vertically mounted baffle 9 that rotates synchronously with the disc 11 on one side, thus preventing the components from falling off due to inertia during the rotation of the disc 11. A divider 12 is provided between the disc 11 and the frame 1, with the divider 12 vertically located on the frame 1 and the disc 11 horizontally located above the divider 12. The divider 12 and the disc 11 are connected by a drive. A servo motor 13 is provided on one side of the divider 12 to drive it, and the servo motor 13 is located at the bottom of the frame 1. The drive between the divider 12 and the servo motor 13 transports each component above the disc 11 to the respective mechanism one by one.

[0029] The component feeding mechanism 3 includes a component vibratory plate 16 mounted on the frame 1, and a track (not shown in the figure) is provided on one side of the component vibratory plate 16 to vibrate and transport the internal component to the working turntable 4. A component support seat 15 is provided at the end of the track to support the component being transported, and a component sensor 14 for sensing the position of the component is provided above the component support seat 15 away from the component support seat 15.

[0030] The nut assembly mechanism 5 includes a nut vibratory plate 22 mounted above the frame 1. A feeding rod 19 is provided on one side of the nut vibratory plate 22 to push the vibrating nut being transported. The feeding rod 19 is located on one side of the working turntable 4.

A first positioning cylinder 21 is also provided on one side of the nut vibrating plate 22 to limit the rotation of the working turntable 4. The first positioning cylinder 21 is horizontally mounted below the spring member 17. When the nut vibrating plate 22 delivers the nut to the feeding rod 19, the nut sensor 18 senses the nut and drives the feeding cylinder 20 to push the feeding rod 19 to push the nut onto the spring member 17. At the same time, the first positioning cylinder 21 limits and fixes the component body transmitted through the working turntable 4, and makes the nut placed on the spring member 17 horizontally mounted above the component. Finally, the pressing cylinder 23 presses the nut through the spring member 17 and into the component body. After the action is completed, each cylinder returns to its original position in turn to wait for the next nut assembly.

[0031] The nut detection mechanism 6 includes a nut detection cylinder 25 disposed on one side of the pressing cylinder 23, and the nut detection cylinder 25 is horizontally mounted above the working turntable 4. A first detection sensor 24 is disposed below the nut detection cylinder 25, parallel to the working turntable 4, and capable of detecting nuts. When the working turntable 4, together with the assembly body equipped with the nut, moves to below the nut detection cylinder 25, the nut detection cylinder 25 drives the first detection sensor 24 to descend above the working turntable 4 and detect the nut on the assembly body on the working turntable 4 through the first detection sensor 24. When the light of the nut detection sensor 24 is on, it indicates that there is no nut in the assembly body; when the light of the nut detection sensor 24 is off, it indicates that there is a nut in the assembly body. This completes the detection work for the assembly of the assembly cover at the next work station.

[0032] The component cover assembly mechanism 7 includes a component cover vibratory plate 27 disposed above the frame 1, and the component cover vibratory plate 27 is located on one side of the nut detection mechanism 6. A component cover support 30 is disposed on one side of the component cover vibratory plate 27 to support and place the component cover vibrating and conveying it. A component cover pusher cylinder 31 is disposed on one side of the component cover support 30 to push the component cover placed on it onto the working turntable 4. A component cover sensor 29 is also disposed on one side of the component cover support 30 to sense the component cover placed on it. A component cover presser cylinder 28 is disposed above the component cover support 30, and the component cover presser cylinder 28 is provided with a lower component cover mechanism 26 to press and assemble the component cover placed above the component cover support 30 with the component body above the working turntable 4.

[0033] The lower component cover mechanism 26 includes a pressure rod 36 driven by a cylinder 28 for pressing the component cover. A fixed plate 38, elastically movable, is provided at the bottom of the pressure rod 36. A stop block 35 is elastically provided on one side of the fixed plate 38. A sliding block 43 is provided between the pressure rod 36 and the fixed plate 38, and a pin 39 is provided between the sliding block 43 and the fixed plate 38. A first spring 37 is elastically provided between the sliding block 43 and the pressure rod 36. The sliding block 43 slides on one side of the fixed plate 38. A pressure block 40 is provided on one side of the sliding block 43, and a second spring 41 is elastically provided on one side of the pressure block 40. A fixed block 42, which moves elastically synchronously with the stop block 35, is provided at the other end of the second spring 41. When the fixed block 42 is locked onto the sliding block 43 by screws, it presses down the second spring 41, allowing the pressure block 40 to slide within a specified distance. When the component cover enters the lower component cover mechanism 26, it is... The pressure block 40 holds the component in place and prevents it from falling off. The sliding block 43 is connected to the pressure rod 39 via a pin 39. The first spring 37 between the sliding block 43 and the pressure rod 39 allows the pressure rod 39 to move up and down within the sliding block 43. The sliding mechanism composed of the aforementioned components is entirely housed within the fixed plate 38. Thus, when the component pressing cylinder 28 retracts, the pressure rod 36 drives the entire sliding block mechanism to rise, while the spring force of the first spring 37 continuously presses down on the sliding block 43, making the sliding block 43 flush with the component cover outlet, facilitating the entry of the component cover into the lower component cover mechanism 26. When the component pressing cylinder 28 extends, the pressure rod 36 drives the entire sliding mechanism to press down. When the stop block 35 fixed on the sliding block 43 does not contact the fixed plate 38, the entire sliding mechanism moves downward. When the stop block 35 contacts the fixed plate 38, the sliding mechanism stops moving while the pressure rod 36 continues to move. Through this lower component cover mechanism 26, the function of assembling the component cover can be realized.

[0034] The lower component cover mechanism 26 also includes a support cylinder 34 disposed below the component cover support 30, and the support cylinder 34 is drivenly connected to the component cover support 30. A second positioning cylinder 33 for positioning the component body is disposed on the other side of the component cover support 30, and a second detection sensor 32 for sensing the assembled component body is disposed at a location above the component cover support 30. Therefore, when the component cover vibratory feeder 27 delivers the component cover to the component cover support 30 and the component cover sensor 29 senses the component cover... When the component cover is pushed, cylinder 31 pushes the component cover into the lower component cover mechanism 26 to wait for assembly. According to the detection result of the nut detection mechanism 6 of the previous station, if there is a nut, the component cover is assembled; if there is no nut, the component cover is not assembled. If there is a nut, the second positioning cylinder 33 lifts and positions the component body, the support cylinder 34 supports it, and the pressing cylinder 28 assembles the component cover into the component body. When the assembly is completed, the second detection sensor 32 starts to detect. If the detection sensor light is on, the finished component is judged as qualified; if the detection sensor light is off, the finished component is judged as unqualified.

[0035] The superior / defective product discharge mechanism 8 includes a discharge cylinder 44 disposed above the frame 1 to hook the component body on the working turntable 4, and a hopper 45 disposed above the frame 1 and inclined to one side of the working turntable 4. A qualified product discharge funnel 47 and a defective product discharge funnel 48 are respectively disposed at the end away from the hopper 45. A superior / defective product cylinder clamp 46 is disposed on one side of the hopper 45 to clamp the assembled component body. The component is hooked from the working turntable 4 into the hopper 45 by the discharge cylinder 44. According to the result of the joint detection of the first detection sensor 24 in the nut detection mechanism 6 and the second detection sensor 32 in the component cover assembly mechanism 7, if it is a qualified product, the superior / defective product cylinder clamp 46 clamps the product into the qualified product discharge funnel 47. If it is a defective product, the superior / defective product cylinder clamp 46 clamps the product into the defective product discharge funnel 48.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
