Specifically, the first drive unit 52 includes a fourth motor, and the second drive unit 53 includes a third motor and a third screw assembly.

[0033] The working process of the feeding mechanism 1 of the present invention is as follows: the horn rack 10 is loaded through the provided vibration plate. During the loading process of the horn rack 10, the second cylinder 132 controls the second stopper 131 to move horizontally to prevent the horn rack 10 from overlapping during the loading process. Before the horn rack 10 enters the horn rack fixture 12, the first cylinder 142 drives the first stopper 141 to extend downward to cooperate with the horn rack fixture 12 to position the horn rack 10 that is about to enter the horn rack fixture 12. After the horn rack 10 enters a horn rack fixture 12, the second motor 151 drives the first screw assembly 152 to rotate to drive the loaded horn rack 10 to enter different horn rack fixtures 12. When all materials are loaded into a group of horn rack fixtures 12 in the feeding mechanism 1, the first cylinder 142 drives the first stop block 141 to retract, and the fourth motor drives the horn rack grasping part 51 to grasp the horn rack 10 and transfer it to the separation mechanism 2. During the transfer process, the rotary cylinder 512 rotates the horn rack 10 180 degrees, and the fourth motor flips the horn rack 10 90 degrees and then places it on the separation mechanism 2.

[0034] The cutting mechanism 2 of the present invention is as follows Figures 6 and 7As shown: it includes a base plate 21, two groups of horn rack positioning parts 23 slidably installed at one end of the base plate 21 through a third mounting frame 22, a horn rack rotating part 24 installed above each horn rack positioning part 23, and a fourth driving part 27 that drives the third mounting frame 22 to drive the horn rack positioning part 23 and the horn rack rotating part 24 to move horizontally along the base plate 21; a first sensor module 25 for sensing the position of the horn rack 10 is installed at each horn rack rotating part 24. The clevis positioning unit 23 includes a positioning rod 231 and a third pneumatic cylinder 232 that drives the positioning rod 231 up and down.

One end of the connecting rod 241 is located above the positioning rod 231, and the other end of the connecting rod 241 is connected to the first motor 242. The fourth driving unit 27 includes a slide rail assembly 273 mounted on the base plate 21, a second screw assembly 272, and a third motor 271 that drives the second screw assembly 272 to rotate, thereby driving the third mounting frame 22 forward and backward along the slide rail assembly 273. Multiple clevis accessory positioning units 26 are mounted on the other end of the base plate 21, each of which is positioned opposite a respective clevis positioning unit 23. The second transport mechanism 6 cooperates with the clevis accessory positioning units 26 to position the clevis accessory 20. The clevis accessory positioning unit 26 includes a support rod 261 and a fourth pneumatic cylinder 262 that drives the support rod 261 to extend and retract.

[0035] The second transport mechanism 6 of the present invention is installed on the assembly platform 31 of the assembly mechanism 3, such as 10 to Figure 11 As shown, the second transport mechanism 6 includes a clevis accessory grasping unit 61, a fifth cylinder 62 that drives the clevis accessory grasping unit 61 up and down, a single-axis manipulator 64 mounted with the fifth cylinder 62, and a third drive unit 63 that drives the fifth cylinder 62 to move the clevis accessory grasping unit 61 horizontally along the single-axis manipulator 64. The clevis accessory grasping unit 61 includes a set of second gripping jaws 611 and a sixth cylinder 612 that drives each second gripping jaw 611 to grasp the clevis accessory 20.

The third drive unit 63 includes a fifth motor, and the clevis accessory 20 is a handle.

[0036] The working process of the separation mechanism 2 of the present invention is as follows: when the third cylinder 232 of the horn rack positioning part 23 lifts the positioning rod 231, the first transport mechanism 5 places the horn rack 10 on the upper end of the horn rack positioning part 23 of the separation mechanism 2 to complete the positioning of the horn rack 10. After positioning, when the first sensor module 25 senses that the horn rack 10 is in place, the first motor 242 of the horn rack rotating part 24 drives the connecting rod 241 to rotate according to the assembly requirements to adjust the position of the horn rack 10 to correspond to the horn rack accessory 20 to facilitate assembly and meet the accuracy requirements of assembly; the positioning rod 231 will retract; at the same time, the second transport mechanism 6 drives the single-axis manipulator 64 through its fifth motor to drive the fifth cylinder 62 to move horizontally, thereby driving the horn rack The rack accessory grasping part 61 moves horizontally, and then the fifth cylinder 62 drives the horn rack accessory grasping part 61 to move up and down, and the sixth cylinder 612 of the horn rack accessory grasping part 61 controls the second clamping claw 611 to grasp the horn rack accessory 20. After grasping, the horn rack accessory grasping part 61 is moved to the assembly station of the assembly mechanism 3. At the same time, the fourth cylinder 262 of the horn rack accessory positioning part 26 drives the support rod 261 to extend and retract to position the horn rack accessory 20; after positioning, the fifth cylinder 62 drives the horn rack accessory grasping part 61 to retract, and the fourth driving part 27 of the separation mechanism 2 drives the third mounting frame 22 to drive the horn rack 10 to move directly to the assembly position of the assembly mechanism 3. The horn rack 10 enters the assembly station, and at this time the horn rack and the handle just fit together.

[0037] The assembly mechanism 3 of the present invention is as follows Figures 8 and 9As shown: it includes an assembly platform 31 installed in the frame 4, and a group of riveting stations 33 with the same structure are arranged side by side on the assembly platform 31. A pin grabbing mechanism 32 is provided on one side of each riveting station 33. The pin grabbing mechanism 32 includes a pin grabbing part 321, a pin transferring part 322 that drives the pin grabbing part 321 to move to the riveting station 33, a pin pushing part 323 that drives the pin 30 to the pin grabbing part 321, and a plurality of second sensor modules 324 that sense the position of the pin 30. At the riveting station 33, there are provided a riveting head 331 and a riveting part 332 which cooperates with the riveting head 331 to complete the assembly work of the horn rack 10. The riveting part 332 is installed above the frame 4. The riveting part 332 includes a riveting rod 3321 which matches the riveting head 331, a double-force cylinder 3322 which drives the riveting rod 3321 to complete the riveting work, and a pressure sensing module 3323 which is arranged between the riveting rod 3321 and the double-force cylinder 3322; a pin suction part 3311 for sucking the pin 30 is provided at the front end of the riveting head 331. Among them, the pin grasping part 321 includes a third clamping jaw 3211 and a seventh cylinder 3212 that controls the third clamping jaw 3211 to pick up and place the pin 10; the pin transferring part 322 includes an eighth cylinder, which is connected to the pin grasping part 321 to drive the pin grasping part 321 to drive the pin 10 to the riveting station 33; the pin pushing part 323 includes a pushing block 3231 and a ninth cylinder 3232 that drives the pushing block 3231 to move; and the pin suction part 3311 includes a magnet.

[0038] The assembly mechanism 3 of the present invention operates as follows: when the horn bracket 10 and the horn bracket accessory 20 arrive at the assembly station, the pin 10 is loaded onto the assembly platform. After the second sensor module 324 senses the pin 30, the ninth cylinder 3232 drives the push block 3231 to push the pin 30 to the third clamping jaw 3211. The seventh cylinder 3212 controls the third clamping jaw 3211 to grasp the pin and, driven by the eighth cylinder, moves the pin to the riveting station 33. After the pin suction portion 3311 at the front end of the riveting head 331 sucks the pin 30 away, it enters the riveting head 331. Simultaneously, the eighth cylinder drives the pin grabbing portion 321 to reset. The multiplying force cylinder 3322 of the riveting unit 332 drives the riveting rod 3321 to move up and down to rivet the pin 30, completing the riveting operation and thus completing the assembly of the horn bracket 10. The pressure sensing module 3323 can sense the pressure applied by the riveting unit 332 during the riveting operation.
