[0064] Specifically, the circuit breaker includes a housing 10 , a thermal system (not shown), and a magnetic system (not shown).

[0065] Specifically, the circuit breaker production line includes a first workstation and a second workstation arranged at intervals in the vertical direction; wherein, an injection molding device 350 is provided at the first workstation, and N first conveyor lines 110 and N assembly devices 120 are provided at the second workstation, the N first conveyor lines 110 and the N assembly devices 120 are arranged in a one-to-one correspondence, and M first spiral conveyor lines 210 are provided between the first workstation and the second workstation; wherein N is an integer greater than 1, and M is an integer greater than or equal to 1.

[0066] Specifically, the injection molding equipment 350 is used to injection mold the shell 10, the first spiral conveyor line 210 is used to convey the shell 10 to at least one first conveyor line 110, the first conveyor line 110 is used to convey the shell 10 to the corresponding assembly equipment 120, and the assembly equipment 120 is used to assemble the thermal system and the magnetic system in the shell 10.

[0067] In this embodiment, the housing 10 can be transmitted to each first conveyor line 110 through the first spiral conveyor line 210, so that the corresponding assembly equipment 120 can assemble the thermal system and the magnetic system in the housing 10. Through the mutual cooperation of the first spiral conveyor line 210 and the first conveyor line 110, automatic feeding of multiple assembly equipment 120 can be realized, effectively preventing the occurrence of insufficient feeding of the housing 10, and improving production efficiency. In addition, the first station and the second station are arranged at intervals in the vertical direction, and the traditional circuit breaker production line is upgraded from a two-dimensional plane layout to a three-dimensional layout, which can make the structure of the entire circuit breaker production line compact, effectively improve space utilization, and provide a solution for lean production in the workshop.

[0068] In this embodiment, by setting up the first workstation, the quality of the housing 10 is controllable and manageable, laying a foundation for the subsequent automation of the second workstation.

[0069] In a feasible implementation, the first workstation is set in one of the two upper and lower workshops, and the second workstation is set in the other, which facilitates the layout planning of the circuit breaker production line. Preferably, the first workstation is set in the lower workshop, and the second workstation is set in the upper workshop.

[0070] In this embodiment, refer to Figure 1 As shown, the first spiral conveyor line 210 includes a translation feeding section 211, a spiral section 212 and a translation discharging section 213 which are arranged in sequence. The translation feeding section 211 is located at the first station, and the shell 10 is transferred to the first spiral conveyor line 210 at the translation feeding section 211; the translation discharging section 213 is located at the second station, and the shell 10 is transferred to one of the first conveyor lines 110 at the translation discharging section 213.

[0071] In this embodiment, the circuit breaker production line may further include an appearance inspection device (not shown), which is used to inspect the appearance of the housing 10 to remove defective products. The appearance inspection device may be located at the first station or at the second station, which is not limited in this application. The appearance inspection device may be a charge coupled device (CCD) inspection module.

[0072] In this embodiment, refer to Figures 2 to 4As shown, the housing 10 includes a bottom shell 11 and an upper cover 12, and the injection molding equipment 350 includes an injection mold and a grabbing and assembling device. The injection molding equipment 350 can mold the bottom shell 11 and the upper cover 12 through the injection mold. After the injection mold is opened, the grabbing and assembling device grabs the bottom shell 11 and the upper cover 12 in the injection mold and assembles the bottom shell 11 and the upper cover 12 together and then transfers them to the first spiral conveyor line 210. Among them, the injection molding of the bottom shell 11 and the upper cover 12 can be completed by a set of injection molds. In this embodiment, the assembly equipment 120 can first separate the bottom shell 11 and the upper cover 12, then assemble the thermal system and the magnetic system in the bottom shell 11, and finally assemble the upper cover 12 together.

[0073] Exemplarily, the grabbing and assembling device includes a mechanical arm and an assembling claw disposed on the mechanical arm, and the mechanical arm drives the assembling claw to move so that the assembling claw is suitable for grabbing the bottom shell 11 and the upper cover 12 in the injection mold, and the assembling claw assembles the bottom shell 11 and the upper cover 12 and then drives the mechanical arm to transfer. Among them, the mechanical arm is a multi-degree-of-freedom mechanical arm.

[0074] In this embodiment, refer to Figure 1 , Figures 5 to 7 As shown, the first station is also provided with a second conveyor line 310 and a steering mechanism 320 disposed between the second conveyor line 310 and the first spiral conveyor line 210; wherein the injection molding device 350 is also used to transfer the shell 10 formed by injection molding to the second conveyor line 310, and the steering mechanism 320 can rotate the shell 10 on the second conveyor line 310 and transfer it to the first spiral conveyor line 210. In this embodiment, the injection-molded shell 10 will be arranged side by side on the second conveyor line 310 along the conveying direction of the second conveyor line 310, and the width direction of the shell 10 is the same as the conveying direction of the second conveyor line 310. After the shell 10 is rotated by the steering mechanism 320, the length direction of the shell 10 transferred to the first spiral conveyor line 210 is the same as the conveying direction of the first spiral conveyor line 210, and the shell 10 is not easy to fall off the first spiral conveyor line 210, which effectively ensures that the shell 10 is smoothly transferred to the first conveyor line 110.

[0075] Exemplarily, the second conveying line 310 and the translational feeding section 211 have the same conveying direction at the steering mechanism 320 , that is, the steering mechanism 320 rotates the housing 10 on the second conveying line 310 by 90° and then transfers it to the translational feeding section 211 .

[0076] Specifically, the steering mechanism 320 includes a steering bracket 321, a turntable 322 and a driving assembly 323. The turntable 322 is rotatably connected to the steering bracket 321, and the turntable 322 is provided with a plurality of positioning grooves 3221 at intervals along the circumferential direction, and the second transmission line 310 can transmit the housing 10 to the positioning grooves 3221; the driving assembly 323 is used to drive the turntable 322 to drive the housing 10 to rotate and transfer it to the first spiral transmission line 210, and the rotation and transfer of the housing 10 are completed by the drive assembly 323 driving the turntable 322, which is convenient, stable and reliable.

[0077] Exemplarily, the driving assembly 323 may be configured as a synchronous belt transmission structure driven by a motor.

[0078] In a feasible implementation manner, a guide block 324 is provided on the steering bracket 321, and a guide channel 3241 is formed between the guide block 324 and the rotating disk 322. The rotating disk 322 can drive the housing 10 to pass through the guide channel 3241, and the guide channel 3241 can guide the rotation of the housing 10. In this embodiment, the provision of the guide block 324 can effectively prevent the housing 10 from escaping from the positioning groove 3221 during the rotation transfer process.

[0079] Exemplarily, the positioning groove 3221 includes a pushing surface 32211 and a positioning surface 32212 set at an angle, the positioning surface 32212 is used to intercept the shell 10 on the second transmission line 310, and the pushing surface 32211 pushes the shell 10 to the guide channel 3241. Under the guidance of the guide channel 3241, the rotation transfer of the shell 10 is completed, and the shell 10 after the rotation transfer is convenient to detach from the positioning groove 3221.

[0080] In a feasible embodiment, a laying block 330 is provided on the first spiral conveyor line 210, and the laying block 330 can push the shell 10 to flip over to the first spiral conveyor line 210, that is, the first side of the shell 10 along the width direction is in contact with the first spiral conveyor line 210, which can increase the contact area between the shell 10 and the first spiral conveyor line 210 to increase the friction force, so that the shell 10 can be stably conveyed on the first spiral conveyor line 210.

[0081] Exemplarily, the laying down block 330 is disposed on the translation feeding section 211 .

[0082] Exemplarily, the tipping block 330 has an extrusion surface 331 inclined toward the first spiral conveyor line 210, and along the conveying direction of the translational feed section 211, the inclination angle of the extrusion surface 331 gradually increases. During the conveying process of the shell 10, the inclined surface squeezes the second side of the shell 10 along the width direction toward the translational feed section 211 to achieve the side flipping of the shell 10. The structure is simple, stable and reliable.

[0083] In some embodiments, Figure 3 and Figure 8 As shown, a third conveying line 340 is also provided at the first station, and the third conveying line 340 is provided between the second conveying line 310 and the first spiral conveying line 210. In this embodiment, the steering mechanism 320 is provided between the second conveying line 310 and the third conveying line 340, and the knocking block 330 is provided on the third conveying line 340. Among them, the steering mechanism 320 can rotate and transfer the shell 10 on the second conveying line 310 to the third conveying line 340; the knocking block 330 can push the shell 10 to flip to the third conveying line 340; the shell 10 flipped on the third conveying line 340 can be transferred to the first spiral conveying line 210. Specifically, the shell 10 flipped on the third conveying line 340 can be transferred to the translation feeding section 211, and while the shell 10 is transferred to the first spiral conveying line 210, the shell 10 can be stably conveyed on the first spiral conveying line 210. It can be understood that the third conveying line 340 is equivalent to an extension section of the translation feeding section 211 , which can buffer the shell 10 and facilitate the position layout of the first spiral conveying line 210 .

[0084] In this embodiment, refer to Figure 2 and Fig. 9 As shown, N loading transfer mechanisms 130 are also provided at the second workstation, and the N first conveyor lines 110 and the N loading transfer mechanisms 130 are arranged one by one; wherein the loading transfer mechanism 130 is used to transfer the shell 10 from the first spiral conveyor line 210 to the corresponding first conveyor line 110, which is stable and reliable.

[0085] Specifically, the loading transfer mechanism 130 includes a loading transfer bracket 131, a guide rod 132, a transmission connecting rod 133, and a loading transfer driving member 134. Among them, two guide rods 132 are arranged in parallel, one end of the guide rod 132 is hinged to the loading transfer bracket 131, and the two ends of the transmission connecting rod 133 are hinged to the two guide rods 132 in a one-to-one correspondence. The loading transfer driving member 134 is arranged on the loading transfer bracket 131 and connected to one of the two guide rods 132. The loading transfer driving member 134 is used to drive the guide rod 132 to rotate between a first angle and a second angle. Among them, through the arrangement of the transmission connecting rod 133, the loading transfer driving member 134 can drive the two guide rods 132 to rotate together. In this embodiment, the guide rods 132 are at a first angle, and the two guide rods 132 can guide the shell 10 to be transmitted on the first spiral conveyor line 210. Specifically, the shell 10 passes between the two guide rods 132 and moves on the translation discharge section 213 under the guidance of the two guide rods 132.

[0086] In some embodiments, the guide rods 132 are at a second angle, and the two guide rods 132 can guide the shell 10 to be transferred from the first spiral conveyor line 210 to the corresponding first conveyor line 110. Specifically, the shell 10 passes between the two guide rods 132 and is transferred to the corresponding first conveyor line 110 in the translation discharge section 213 under the guidance of the two guide rods 132.

[0087] In other embodiments, the guide rod 132 rotates from the first angle to the second angle to push the outer shell 10 from the first spiral conveyor line 210 to the corresponding first conveyor line 110, specifically, it can push the outer shell 10 from the translation discharge section 213 to the corresponding first conveyor line 110, which is stable and reliable.

[0088] In some embodiments, the first conveyor line 110 is arranged at intervals along the conveying direction of the corresponding translational discharge section 213. The loading transfer mechanism 130 is disposed between the corresponding first conveyor line 110 and the translational discharge section 213. It is worth mentioning that the two adjacent shells 10 can be abutted against each other before the steering mechanism 320 rotates; the two adjacent shells 10 are arranged at intervals along the conveying direction of the translational feed section 211 after the steering mechanism 320 rotates. When the guide rod 132 is at the second angle or rotates from the first angle to the second angle, because the shells 10 on the translational feed section 211 are arranged at intervals, when one shell 10 is transferred to the corresponding first conveyor line 110, another shell 10 adjacent to the shell 10 has not yet moved between the two guide rods 132, ensuring that the shells 10 on the translational discharge section 213 can be stably transferred one by one to the corresponding first conveyor line 110.

[0089] In other embodiments, Figure 2As shown, a fourth conveyor line 140 is also provided at the second station. In this embodiment, the feed end of the fourth conveyor line 140 corresponds to the translational discharge section 213, the first conveyor line 110 is arranged at intervals along the conveying direction of the fourth conveyor line 140, and the loading transfer mechanism 130 is provided between the fourth conveyor line 140 and the first conveyor line 110. It can be understood that the fourth conveyor line 140 is equivalent to an extension of the translational discharge section 213, which can buffer the shell 10. Exemplarily, the fourth conveyor line 140 can include at least two conveyor sections arranged at an angle, which facilitates the overall layout of the second station and effectively ensures the compact structure at the second station. In this embodiment, the discharging section 213 is translated to convey the shell 10 to the fourth conveying line 140, the guide rod 132 is at a first angle, the shell 10 passes between the two guide rods 132 and moves on the fourth conveying line 140 under the guidance of the two guide rods 132; the guide rod 132 is at a second angle, the shell 10 passes between the two guide rods 132 and is transferred from the fourth conveying line 140 to the corresponding first conveying line 110 under the guidance of the two guide rods 132; or the guide rod 132 is rotated from the first angle to the second angle to push the shell 10 from the fourth conveying line 140 to the corresponding first conveying line 110, which is stable and reliable.

[0090] In a possible implementation, Fig.10 As shown, one of the first conveyor lines 110 and the discharge end of the fourth conveyor line 140 is arranged opposite to each other, and the loading transfer mechanism 130 may not be provided at the first conveyor line 110. The housing 10 can be directly transferred from the discharge end of the fourth conveyor line 140 to the first conveyor line 110, thereby simplifying the overall structure of the circuit breaker production line.

[0091] In a feasible implementation, one first spiral conveyor line 210 corresponds to at least one fourth conveyor line 140. For example, to facilitate the layout of the second station and avoid the conveying distance of the fourth conveyor line 140 being too long, Figure 2 and Fig.10 As shown, a first spiral conveyor line 210 corresponds to a plurality of fourth conveyor lines 140, the translation discharge section 213 and the plurality of fourth conveyor lines 140 are arranged in sequence, and the fourth conveyor line 140 is arranged corresponding to at least one first conveyor line 110. It can be understood that along the conveying direction of the shell 10, in two adjacent fourth conveyor lines 140, the shell 10 can be transferred from the discharge end of the front fourth conveyor line 140 to the rear fourth conveyor line 140, and the shell 10 on the fourth conveyor line 140 can be transferred to the corresponding first conveyor line 110, which is convenient for feeding the shell 10.
