Description

Technical Field

[0001] This invention relates to the field of circuit breaker manufacturing technology, and more specifically, to an automated production equipment for miniature circuit breakers. Background Technology

[0002] The automated production of miniature circuit breakers involves multiple stages, among which the automated assembly of the copper contacts, i.e., the terminal blocks, is a crucial step. The quality of the copper contacts produced is directly related to the reliability and stability of the cable-terminal connection during subsequent use of the miniature circuit breaker.

[0003] In the prior art, a miniature circuit breaker automated production equipment with publication number CN118951743A includes a rotary table, a feeding device, a clamping device, and a picking device. An assembly base and a rotary cylinder are provided on the rotary table. Multiple clamping devices are provided, each with a feeding device next to it. Different feeding devices contain different copper head components. The picking device and clamping devices are arranged in an arc along the rotary table. Each clamping device has a clamping claw, and each picking device has a picking claw. The clamping claw can clamp the copper head component from the feeding device onto the assembly base. Subsequently, the rotary cylinder drives the rotary table to rotate, causing the assembly base to rotate under the next clamping claw or the picking claw. The picking claw moves downward and removes the copper head component from the assembly base. This invention is used for the automated assembly production of multiple copper head components to improve the automated production efficiency of miniature circuit breakers using this type of copper head.

[0004] However, while existing automated circuit breaker production equipment can perform intermittent assembly of circuit breakers relatively well, its multi-purpose drive source for the rotating drive turntable is not very effective when placing circuit breakers on the equipment for intermittent assembly, reducing the mechanical energy utilization rate of the production equipment. Furthermore, the automatic lubrication compensation for the drive parts is ineffective, causing the turntable to jam and affecting the circuit breaker assembly efficiency. Additionally, the vibration adjustment effect is poor for circuit breakers of different sizes, and the coordination between gas and camera during circuit breaker feeding is not high, resulting in poor real-time identification of part orientation and inadequate correction of incorrectly oriented parts by blowing material. These shortcomings fail to meet user needs. Therefore, we propose a small-scale automated circuit breaker production equipment. Summary of the Invention

[0005] To address the problems mentioned in the background, this invention provides an automated production equipment for miniature circuit breakers, which solves the problems mentioned in the background art such as the low multi-purpose use effect of the drive source when the placement drive turntable rotates, the reduced mechanical energy utilization rate of the production equipment, and the poor real-time identification of part orientation and the inadequate blowing correction of parts with incorrect posture.

A nozzle 20 is fixedly connected to one end of the spray pipe 19. The vibration amplitude of the vibrating screen can be adjusted by the frequency converter motor 8 to meet different sizes. When the small parts are automatically fed, the rotation of the first gear 15 drives the suction fan 16, which delivers dry gas into the spray pipe 19 and sprays it out through the nozzle 20. Under the action of the high-speed camera 12, the feeding trajectory of the parts in the feeding frame is automatically identified and corrected. At the same time, under the long-term rotation of the first gear 15, the temperature sensor automatically operates the opening and closing of the control valve 24, which causes the graphene lubricating film to be sprayed out from the lubrication nozzle 23, achieving the effect of self-lubrication of the meshing parts of the gear and improving the accuracy of the circuit breaker assembly position.

[0040] like Figure 2 and Figure 3 As shown, the outer wall of the vibrating feeding screen 7 is equipped with a variable frequency motor 8, the spray pipe 19 and the telescopic plate 10 are fixedly connected, the connection between the nozzle 20 and the spray pipe 19 is inclined, and the outer wall of the main body 1 is equipped with a discharge plate 5, which is conducive to achieving the effect of adjusting the vibration amplitude according to the size of the parts by using the variable frequency motor 8 installed on the outer wall of the vibrating feeding screen 7.

[0042] like Figures 6-8As shown, a suction fan is installed inside the spray pipe 19. The rotation center of the first gear 15 is fixedly connected to the fan blades inside the suction fan body 16, which facilitates the full intake of the treated dry gas through the suction fan installed inside the spray pipe 19.

[0044] like Figure 9 As shown, the graphene lubricating film processing box 21 contains copper foil raw materials, heating components, and carbon-containing gases such as methane, which facilitates the convenient generation and processing of graphene lubricating films.

[0045] like Figure 10 and Figure 11 As shown, the outer wall of the first gear 15 meshes with the second gear 25. The rotation center of the second gear 25 is fixedly connected to the intermittent turntable 26. The rotation center of the intermittent turntable 26 is fixedly connected to the rotating rod 27. One end of the rotating rod 27 is fixedly connected to the connecting column 28. The outer wall of the connecting column 28 is slidably connected to the intermittent wheel 29, which is rotatably connected to the inner wall of the control box 4. The rotation center of the intermittent wheel 29 is fixedly connected to the rotating shaft 33, which is fixedly connected to the bottom of the connecting shaft 2. This arrangement of the rotating shaft 33 and the intermittent wheel 29 facilitates the synchronous intermittent rotation of the processing turntable 3, thereby achieving the effect of automated production and assembly of various components of the circuit breaker.

[0046] like Figure 10 As shown, the intermittent groove 30 is provided at the connection between the outer wall of the intermittent wheel 29 and the connecting column 28, the fan-shaped groove 31 is provided at the connection between the outer wall of the intermittent wheel 29 and the intermittent turntable 26, and the fan-shaped notch 32 is provided on the outer wall of the intermittent wheel 29. This facilitates the effect of driving the processing turntable 3 to rotate intermittently through the intermittent groove 30 provided at the connection between the outer wall of the intermittent wheel 29 and the connecting column 28.

[0047] like Figure 5As shown, the outer wall of the main body 1 of the equipment is provided with a first electric push rod 36, one end of the first electric push rod 36 is fixedly connected to a sliding rod 37, the outer wall of the sliding rod 37 is provided with a vision camera 38, one end of the sliding rod 37 is fixedly connected to a push plate 39, the outer wall of the main body 1 of the equipment is provided with a second electric push rod 40, one end of the second electric push rod 40 is fixedly connected to a top rod 41;

[0048] The lifting height of the top rod 41 is matched with the pushing level of the pusher plate 39, which facilitates the automatic pushing and unloading of the assembled circuit breaker through the setting of the top rod 41 and the pusher plate 39. When the vision camera 38 recognizes the assembled circuit breaker, it drives the first electric push rod 36 to drive the pusher plate 39, which is fixedly connected to the sliding rod 37, to move in an extension and retraction motion. At the same time, it drives the second electric push rod 40 to drive the top rod 41 to move upward, so that the lifted circuit breaker is pushed to the unloading plate 5 under the action of the pusher plate 39 for automatic unloading, thereby improving the efficiency of automated circuit breaker production.

[0049] like Figure 6 As shown, a second servo motor 42 is provided on the outer wall of the assembly box 34. A threaded rod 43 is fixedly connected to the output end of the second servo motor 42. A lifting rod 44 is threadedly connected to the outer wall of the threaded rod 43 and slidably connected to the outer wall of the assembly box 34. A lifting groove 45 is provided at the connection between the outer wall of the assembly box 34 and the lifting rod 44. A pulling rod 46 is rotatably connected to the outer wall of the lifting rod 44.

A limit groove 4 is provided at the connection between the outer wall of the assembly box 34 and the positioning plate 47. 8. The positioning plate 47 is used to achieve the effect of limiting the processing of circuit breakers of different sizes. When the circuit breaker is processed in an automated production process through the assembly box 34, in order to improve the stability of the circuit breakers of different sizes placed in the assembly box 34, the second servo motor 42 is turned on and the threaded rod 43 is rotated to drive the lifting rod 44 to slide along the inner wall of the lifting groove 45. The sliding of the lifting rod 44 drives the positioning plate 47 to slide along the inner wall of the limiting groove 48 through the rotation of the pulling rod 46, so as to achieve the effect of limiting and fixing the circuit breakers of different sizes on both sides.

[0050] Working principle:

[0051] like Figure 1-11As shown, when the automatic circuit breaker production equipment is in use, firstly, the vibration amplitude of the vibrating screen is adjusted by the frequency converter motor 8 to meet the automatic feeding of parts of different sizes. Then, the rotation of the first gear 15 drives the suction fan body 16, which delivers dry gas into the spray pipe 19 and sprays it out through the nozzle 20. Under the action of the high-speed camera 12, the feeding trajectory of the parts in the feeding frame is automatically identified and corrected. At the same time, under the long-term rotation of the first gear 15, the opening and closing of the control valve 24 is automatically operated by the temperature sensor, which causes the graphene lubricating film to be sprayed out from the lubrication nozzle 23, achieving the effect of self-lubrication of the meshing parts of the gear and improving the accuracy of the circuit breaker assembly position.

[0052] Next, when the vision camera 38 recognizes the assembled circuit breaker, it drives the first electric push rod 36 to drive the push plate 39, which is fixedly connected to the sliding rod 37, to extend and retract. At the same time, it drives the second electric push rod 40 to drive the top rod 41 to rise, so that the circuit breaker being lifted is pushed to the unloading plate 5 under the action of the push plate 39 for automatic unloading, thereby improving the efficiency of automated circuit breaker production.

[0053] Finally, during the automated production of the circuit breaker via the assembly box 34, in order to improve the stability of placing circuit breakers of different sizes within the assembly box 34, the second servo motor 42 is turned on. Through the rotation of the threaded rod 43, the lifting rod 44 slides along the inner wall of the lifting groove 45. The sliding of the lifting rod 44, through the rotation of the pull rod 46, causes the positioning plate 47 to slide along the inner wall of the limiting groove 48, thereby achieving the effect of limiting and fixing the circuit breakers of different sizes on both sides.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way.
