[0061] Further, a shell carrying manipulator 31 for carrying the shell is arranged between the shell conveying unit 21 and the accompanying clamp 13. The shell carrying manipulator 31 is bolted to the workbench and connected to the manipulator mounting side plate 171 at the other end by bolts. When the shell is conveyed to the loading channel 213 by the plate chain conveying structure 211, the shell carrying manipulator 31 will carry the shell from the loading channel 213 to the adjacent accompanying clamp 13 after detection by the sensor.

[0062] Referring to Figures 7-9 The cover removal assembly 32 and the shell loading detection assembly 41 will be described in detail.

[0063] The small circuit breaker automatic flexible assembly line further comprises a cover removal assembly 32 for separating the upper shell cover from the lower shell cover, and a shell loading detection assembly 41 is arranged between the shell conveying unit 21 and the cover removal assembly 32.

[0064] Specifically, the shell loading detection assembly 41 comprises a shell loading detection fixed top plate 411, a telescopic cylinder 412, and a shell loading detection guide plate 413 arranged at the telescopic end of the telescopic cylinder 412.

[0065] One end of the shell loading detection fixed top plate 411 is bolted between the fixed frame 172 and the manipulator mounting side plate 171, and the telescopic cylinder 412 is bolted to the end of the shell loading detection fixed plate 411. When the shell loading detection assembly 41 detects that the accompanying clamp 13 carries a shell, the accompanying clamp 13 runs to the cover removal assembly 32.

[0066] Specifically, the cover removal assembly 32 comprises a cover removal carrying manipulator 321 and a cover removal positioning mechanism 322.

[0067] The cover removal carrying manipulator 321 is provided with a support column 3211 for fixing, i.e. the cover removal carrying manipulator 321 is fixed on the workbench by the support column 3211 and connecting bolts, and the cover removal carrying manipulator 321 is arranged above the accompanying clamp 13.

[0070] When the shell-equipped traveling clamp 13 is positioned at the cover removing assembly 32, the cover removing positioning mechanism 322 clamps the lower cover of the shell through the cover removing clamping claw 3225, while the cover removing handling manipulator 321 moves downward to clamp the upper cover of the shell and carries it to be fixed on the traveling clamp 13. At this time, the upper cover and the lower cover of the shell are in a separated state and are both fixed on the traveling clamp 13 through the positioning pins 134.

[0071] Further, the annular rotary machine 10 is also provided with a handle assembly loading manipulator 331, and the cover removing assembly 32 and the handle assembly loading manipulator 331 are further provided with a cover removing detection assembly 42. The cover removing detection assembly 42 is bolted on the fixed frame 172 and the mechanical installation side plate, and in particular, the cover removing detection assembly 42 and the shell detection assembly are arranged on the left and right sides of the cable protection cover 16, respectively.

[0072] Reference Figure 10 The cover removing detection assembly 42 is described in detail.

Pneumatic speed regulating valves 425 are arranged on both sides of the mini cylinder 423, and a pressure reducing valve 426 is bolted on the cover removing detection extending plate 421.

[0074] When the running trolley clamp 13 reaches the position below the cover detection assembly 42 after the cover of the shell is removed, the empty clamp detection head 424 extends downward to detect under the control of the mini air cylinder 423, and when it is determined that the shell is in a separated state at this time, the running trolley clamp 13 continues to run to the handle assembly loading manipulator 331 to install the handle.

[0075] Specifically, the handle assembly assembly unit 33 for assembling the handle and the torsional spring is further included in the small circuit breaker automatic flexible assembly line.

[0076] Referring to Figures 11-17 The handle assembly assembly unit 33 is described in detail.

[0077] The assembly unit includes a handle feeding assembly 332, a torsional spring feeding assembly 333, a rotatable handle torsional spring assembly table 334, a handle loading manipulator 335, a torsional spring loading manipulator 336, a handle assembly unloading manipulator 339, and a handle assembly unloading conveying mechanism 338.

[0078] Specifically, the handle feeding assembly 332 includes a handle vibration disc 3321 and a handle material channel 3322 connected with the handle vibration disc for conveying the handle, and the other end of the handle material channel 3322 is further provided with a handle transition station 3323 installed on the workbench. The handle is conveyed from the vibration disc to the handle transition station 3323 through the handle material channel 3322.

A handle in-place optical fiber support for installing the handle in-place detection optical fiber 33234 is arranged on the side of the handle transition vertical plate 33231. An open structure groove 1311 is arranged on the material blocking block 33233, and the top of the handle abuts against the handle in-place optical fiber after the handle is conveyed to the groove 1311 of the material blocking block 33233 through the handle material channel 3322.

[0080] Further, the handle loading manipulator 335 transfers the handle on the handle transition station 3323 to the handle torsional spring assembly table 334. The handle torsional spring assembly table 334 includes a driving motor 3341 and a rotating disc 3342 rotated by the driving motor 3341, and a handle assembly assembly clamp 3344 is arranged on the rotating disc 3342 through bolts.

[0081] The torsion spring feeding assembly 333 is transported in the same way as the handle feeding assembly 332, that is, the torsion spring feeding assembly 333 includes a torsion spring vibration disc 3331 and a torsion spring channel 3332 arranged at one end of the vibration disc, and the other end of the torsion spring channel 3332 is further provided with a torsion spring transition station 3333. The torsion spring is transported to the torsion spring transition station 3333 through the torsion spring channel 3332, and then transported to the handle assembly assembly jig 3344 by the torsion spring feeding manipulator 336.

[0082] Preferably, the handle torsion spring assembly table 334 further includes a fixed disc 3343 which is concentric with the rotating disc 3342, and the empty clamp detection assembly 34, the torsion spring detection assembly 35, the torsion spring rotating installation assembly 36 and the torsion spring assembly detection assembly 37 are fixed on the fixed disc 3343 by bolts.

[0083] When the handle assembly assembly jig 3344 runs to the empty clamp detection assembly 34, the empty clamp detection assembly 34 judges whether the handle assembly assembly jig 3344 carries a handle, and if there is a handle, the next step is performed, and if there is no handle, all the remaining steps are skipped, and the handle assembly assembly jig 3344 continues to wait at the handle feeding manipulator 335. The running logic of the torsion spring detection assembly 35, the torsion spring rotating installation assembly 36 and the torsion spring assembly detection assembly 37 is the same.

[0084] Specifically, the front ends of the handle feeding manipulator 335, the torsion spring feeding manipulator 336 and the handle assembly feeding manipulator 339 are provided with support assemblies 38, and the bottoms of the support assemblies 38 are bolted to the fixed disc 3343.

That is, when the carrying carrier 2511 with the magnetic assembly moves to the discharging positioning mechanism 253, the rear magnetic assembly grabbing claw 6114 takes out the magnetic assembly from the carrying carrier 2511 and places it on the magnetic assembly rubbing mechanism 662. Then the rear magnetic assembly grabbing claw 6114 continues to grab the magnetic assembly on the discharging positioning mechanism 253, while the front magnetic assembly grabbing claw 6114 grabs the magnetic assembly on the magnetic assembly rubbing mechanism 662 and assembles it in the shell lower cover at the same time as the next magnetic assembly is placed in the magnetic assembly rubbing mechanism 662. That is, the two magnetic assembly grabbing claws 6114 move synchronously.

[0101] With reference to Figure 20The blank positioning mechanism 253 is described in detail.
