During the horizontal driving process of the cylinder three 35, the clamping shaft 36 is used to push the push plate 33 to rotate, so as to control the end of the push plate 33 to move into the material guide table 3, and move the molded case circuit breaker in the material guide table 3 toward the L-shaped plate 26. The molded case circuit breaker is clamped by the cylinder two 25 and the cylinder four 37 to position the molded case circuit breaker on the riveting station.

[0050] like Figure 6 As shown, a slide 51 is fixedly provided on the unloading rack 5, a cylinder 52 is slidably provided on the slide 51, a clamp 53 is fixedly connected to the output end of the cylinder 52, and an unloading plate 54 is fixedly provided on one side of the unloading rack 5. The clamp 53 clamps the molded case circuit breaker in the guide platform 3. After clamping the molded case circuit breaker, the riveted molded case circuit breaker is placed on the unloading plate 54 for automatic unloading.

[0051] like Figure 7-10 As shown, symmetrically distributed riveting plates 41 are fixed on the riveting assembly 4, a reinforcement rod is fixed between the two riveting plates 41, and the two riveting plates 41 are fixed by the reinforcement rod.

A triangular block 43 is fixedly provided at one end of the support rod 47, and a spring 48 is fixedly provided on one side of the triangular block 43, which is fixedly connected to the side surface of the riveting plate 41 through one end of the spring 48.

[0053] A driven plate 44 is fixedly provided at one end of the guide rod 49, and a pressure rod 401 is fixedly provided at the other end. A spring 2 403 is sleeved on the guide rod 49, and one end of the spring 2 403 is fixedly connected to the riveting plate 41. Under normal conditions, the spring 2 403 maintains a thrust to push the guide rod 49 outward, so that the two pressure rods 401 are located on both sides of the feed hole 42, which will not affect the discharge of the rivet rod 402 from the feed hole 42 and its insertion into the rivet hole of the molded case circuit breaker.

[0054] When the rivet rod 402 is installed into the rivet hole, the driven plate 44 pushes the guide rod 49 toward the lower hole 42 until the two guide rods 49 fit together to seal the lower hole 42, and the guide rod 49 is located above the rivet rod 402. Finally, the riveting plate 41 moves downward to make the guide rod 49 press the rivet rod 402 to perform the riveting operation.

[0055] Lifting blocks 45 are slidably provided on both sides of the riveting plate 41, and a sliding rod 46 is fixedly provided on the lifting block 45.

In a normal state, the lower end height of the lifting block 45 is lower than the bottom of the riveting plate 41.

[0056] One side of the lifting block 45 is slidably connected to the hypotenuse of the triangular block 43, and the other side is provided with a bevel groove, which is slidably connected to the driven plate 44. When the lifting block 45 moves down with the riveting plate 41, the lifting block 45 first contacts the molded case circuit breaker, and then the riveting plate 41 moves down. The lifting block 45 squeezes the spring three upward, and the lifting block 45 pushes the triangular block 43 to move away from the riveting plate 41. The support rod 47 moves out of the feed hole 42. At this time, the rivet rod 402 falls into the rivet hole.

[0057] The lifting block 45 pushes the driven plate 44 to move inwardly of the riveting plate 41 , so that the two guide rods 49 are close to each other, and then the guide rods 49 are used to press down the riveting rods 402 to perform the riveting operation.

[0058] like Fig.11 , Fig.12 As shown, a feeding plate 61 is fixedly provided on the feeding member 6 for conveying the molded case circuit breaker housing, one end of the feeding plate 61 is slidably provided with a symmetrically distributed side frame 64, a cylinder 62 is fixedly provided on the feeding member 6, a clamping plate 63 is fixedly provided on the output end of the cylinder 62, the clamping plate 63 is fixedly connected to the side frame 64, and the clamping plate 63 is slidably connected to the positioning groove 31 to fix the molded case circuit breaker housing assembled with electronic components on the guide platform 3.

[0059] A gear 66 is rotatably provided on the side frame 64, and a cylinder 65 is fixedly connected to the axis of the gear 66. A positioning sleeve 67 is fixedly provided on the cylinder 65. A rack 68 is provided on the gear 66, and one end of the rack 68 is fixedly connected to a limiting rod 69. The rack 68 and the limiting rod 69 are arranged parallel to each other. When the side frame 64 is slidably connected to the feed plate 61, the limiting rod 69 slides above the positioning sleeve 67 to limit the rotation of the cylinder 65.

[0060] Then, after the positioning sleeve 67 is separated from the end of the limiting rod 69, the gear 66 is meshed with the rack 68. At this time, the gear 66 drives the cylinder 65 to rotate, and the molded case circuit breaker housing clamped between the two cylinders 65 is rotated. After rotating 180 degrees, the inner wall of the housing is rotated downward, and the housing is aligned toward the clamping plate 63 to fix the molded case circuit breaker.

[0061] The loading part 6 also includes a stand 60 located at one end of the conveying plate 61, and the stand 60 is fixedly installed on the machine table 2. A slide 601 is slidably provided on the stand 60, and a cylinder eight 602 is fixedly provided on the slide 601. The output end of the cylinder eight 602 is vertically downward, and the output end of the cylinder eight 602 is fixedly connected with a suction cup for adsorbing and fixing the molded case circuit breaker shell after the flip, and then the molded case circuit breaker shell is moved down to the clamping plate 63 to fix the molded case circuit breaker installation, thereby completing the assembly of the molded case circuit breaker.

[0063] When the side frame 64 moves toward the slide 601, the end of the side frame 64 is slidably connected to the hypotenuse of the right-angle plate 605, controlling the slide 601 to gradually move downward, so that the suction cup at the output end of the cylinder eight 602 is close to the flipped molded case circuit breaker shell, and then the output end of the cylinder eight 602 is extended, so that the suction cup fits the outside of the shell to absorb the shell, so as to facilitate the movement of the shell for assembly of the molded case circuit breaker.

[0064] In this embodiment, the model of each cylinder is: HB-DJ801, and the model of each slide is: uFS20-60.

[0065] Here’s how it works:

[0066] After the components on the molded case circuit breaker are assembled, the molded case circuit breaker is then transported in sequence onto the U-shaped material guide table 3, the molded case circuit breaker is fixed by cylinder six 62, and the other half of the shell is transported by the loading piece 6. The shell is translated by the side frame 64 and rotated 180 degrees. The shell is located above the molded case circuit breaker, and the output end of the cylinder eight 602 is used to push the suction cup downward to adsorb the shell and assemble it on the molded case circuit breaker. After the shell buckle assembly operation is completed.

[0067] The molded case circuit breaker moves to one side of the push plate 33 of the material guide table 3, and the push plate 33 is rotated to translate the plastic circuit breaker to the L-shaped plate 26. The molded case circuit breaker is clamped by cylinder 25 and cylinder 4 37 to position the molded case circuit breaker on the riveting station. Then the output end of the hydraulic cylinder 23 drives the riveting assembly 4 to move downward to send the rivet rod 402 into the rivet hole of the molded case circuit breaker and complete the stamping of the rivet rod 402.

[0068] When one molded case circuit breaker is riveted, it is pushed by another molded case circuit breaker sent to the riveting station, and then the assembled molded case circuit breaker moves to cylinder 24, and the molded case circuit breaker is pushed by cylinder 24 to move to the unloading rack 5. When the molded case circuit breaker 5 moves to the unloading rack 5, the molded case circuit breaker in the guide table 3 is clamped by the clamp 53. After clamping the molded case circuit breaker, the riveted molded case circuit breaker is placed on the unloading plate 54 for automatic unloading.
