Technical Field

[0001] The present invention relates to the technical field of circuit breaker assembly, and in particular to an assembly device for a thermal-magnetic system. Background Art

[0002] A circuit breaker generally includes a housing, in which an actuator, an electromagnetic system, a thermal tripping system, and a wire part are provided. Wiring terminals are provided on both sides of the housing. Among them, conduction between the actuator and the electromagnetic system is completed through moving and static contacts; the actuator includes a rotating handle rotatably provided on the housing, a moving contact is provided at the lower end of the rotating handle, a swing rod and a V-shaped swing arm are rotatably provided on the rotating handle, the electromagnetic system includes a moving iron core and a coil, the coil is wound around the moving iron core, and both ends of the coil are respectively connected to the static contact and a wiring board, the wiring board is connected to one of the wiring terminals, and the thermal tripping system includes a bimetal piece connected to the other wiring terminal. When an overload current appears in the circuit breaker, the bimetal piece is heated and bent, driving the V-shaped swing arm to rotate clockwise, pressing down the swing rod and then causing the rotating handle to rotate, and finally tripping the circuit breaker. When a short circuit occurs at the outgoing line of the circuit breaker, a large short-circuit current passes through the coil, generating a large magnetic field, causing the moving iron core to impact and rotate the swing rod, and then causing the rotating handle to rotate, and finally tripping the circuit breaker.

The existing assembly method mainly relies on manual assembly. First, the magnetic system is assembled and then installed into the housing to form assembly one, and then the thermal system is installed into the housing to form assembly two. However, the manual assembly method has extremely low efficiency and is not suitable for the long-term development of enterprises. Summary of the Invention

The positioning shaft loading member 263 is driven by a cylinder to slide, and a feeding channel 2631 communicating with the positioning shaft loading channel 262 or the assembly channel 2611 is provided on the positioning shaft loading member 263. The positioning shaft installing member 264 is located above the assembly channel 2611. A second driving member 2612 for driving the positioning shaft installing member 264 to enter and exit the feeding channel 2631 and the assembly channel 2611 is provided on the fixing frame 261. A loading tray is provided on the second frame 21. The loading tray is communicated with the positioning shaft loading channel 262 through a connecting pipe. Two positioning shaft loading channels 262, two positioning shaft loading members 263, two installation channels 192 and two positioning shaft installing members 264 are provided, and the positioning shafts of two circuit breaker housings can be installed and positioned simultaneously, which is more efficient. The positioning shafts enter the positioning shaft loading channel 262 in sequence and are in a vertical state. When the feeding channel 2631 is coaxially arranged with the positioning shaft loading channel 262, the last positioning shaft enters the feeding channel 2631. The positioning shaft loading member 263 slides on the fixing frame 261. When the feeding channel 2631 is coaxially arranged with the installation channel 192, the positioning shaft enters the installation channel 192. At this time, the positioning shaft installing member 264 enters the installation channel 192 under the action of the second driving member 2612, so as to install the positioning shaft into the circuit breaker housing. After the positioning shaft installing member 264 returns to its original position, the positioning shaft loading member 263 also returns to its original position, and continues the feeding and installation of the next positioning shaft.

A guiding shaft is provided on the installation frame. The detection member 271 slides in the guiding shaft. A spring is provided between the detection member 271 and the guiding shaft. When the detection member 271 moves down and touches the positioning shaft, the spring plays a buffering role to avoid the hard contact between the detection member 271 and the positioning shaft. Whether a positioning shaft is installed in the circuit breaker housing is judged according to the moving distance of the detection member 271. The empty carrier blanking mechanism 29 includes an empty carrier blanking area 291 and an empty carrier blanking member. The component two blanking mechanism 24 includes a component two blanking channel and a component two blanking member. Equipment one 1 assembles the magnetic system and puts it into the housing to form component one.

The placement slots can position each component, facilitating subsequent clamping and placing into the housing at one time, corresponding to the positions in the housing for accommodating each component. The housing loading mechanism 13 sequentially loads the housing. After the magnetic system is installed in the housing, it forms Component 1, and is unloaded through the Component 1 unloading channel 141. The Component 1 unloading channel 141 enters Device 2, where Component 1 is loaded. After the thermal system is assembled, it is installed in a thermal system carrier and loaded through the thermal system carrier. The thermal system carrier flows on the second carrier loop 22. Component 1 first passes through a positioning shaft loading and installation mechanism 26 to install the positioning shaft on Component 1, and then passes through a positioning detection mechanism to detect whether the positioning shaft is installed on Component 1. Then, a thermal system installation into housing mechanism 28 installs the thermal system in the second carrier loop 22 into Component 1 to complete the assembly, forming Component 2. Finally, it is sent out of Device 2 through the Component 2 unloading channel 241. The high-precision assembly of the thermal magnetic system is realized automatically, improving the assembly efficiency and having good assembly effect at the same time. There are two Component 1 unloading channels 141 and two Component 2 unloading channels 241, which are a qualified unloading channel and an unqualified unloading channel respectively. The qualified unloading channel of Component 1 extends into Device 2. Second vision sensors are provided on the front sides of the Component 1 unloading mechanism 14 and the Component 2 unloading mechanism 24 to detect whether the product is assembled qualified. If it is assembled qualified, it is clamped by a unloading part and flows out through the qualified unloading channel; if it is unqualified, it enters the unqualified unloading channel through the unloading part. Control devices are also provided on the two racks, and each driving part and motor are controlled by the control device. The information collected by the vision sensor is transmitted to the control device. The control device belongs to the prior art and can be directly purchased from the market. The connection and cooperation between the control device and each driving part and each sensor are not the technical problems to be solved by the present invention; therefore, it will not be specifically described hereinafter.

The driving assembly 193 drives the pick-up member 191 to move along the X-axis, Y-axis, and Z-axis directions of the corresponding frame, so as to clamp the magnetic system or the thermal system on the carrier loop line into the corresponding installation channel 192 and install it into the housing. The driving assembly 193 includes a number of cylinders and a number of slide rails. Each housing in the installation channel 192 is transported by the first handling fork 194, which is more convenient and more accurate than a conveyor belt, making the housing correspond to each mechanism and facilitating the installation of each component into the housing.

[0016] The first vehicle loop 12 includes an annular fixing frame 123, a conveyor belt 124, and a motor and a transmission pulley set for driving the conveyor belt 124 to operate. The motor is fixedly arranged on the annular fixing frame 123, and each vehicle tooling 121 is fixedly arranged on the outer side wall of the conveyor belt 124. An annular track 1231 is provided on the annular fixing frame 123 outside the conveyor belt 124. A pulley 1211 is provided on the lower end surface of each vehicle tooling 121, and each pulley 1211 is in annular sliding fit. A convex edge is provided on the annular track 1231, and a corresponding groove is provided on the pulley 1211. The convex edge is located in the groove. The pulley 1211 is matched with the annular track 1231 to improve the stability of the magnetic system vehicle 122, making it move more smoothly when driven by the conveyor belt 124, and preventing the components in the magnetic system vehicle 122 from being displaced and affecting subsequent assembly. A first positioning mechanism 111 is provided on the first frame 11. The first positioning mechanism 111 includes a first positioning component 1111 and a second positioning component 1112.

The two second positioning components 1112 each include a second positioning member 11121 and a seventh driving member 11122 for driving the second positioning member 11121 to move up and down. Through grooves are formed on the annular fixing frame 123 corresponding to the positions of the positioning members. The positioning members are slidably arranged in the corresponding through grooves, and a positioning notch for inserting the vehicle tooling 121 is provided at the upper end of the positioning member. A guide rail is provided on the annular fixing frame 123, and a guide groove is provided on the mounting plate 11111. The guide rail is located in the guide groove, and the mounting plate 11111 moves up and down along the guide rail, playing a guiding role and being more stable during sliding. The motor drives the conveyor belt 124 to move through the transmission pulley set, thereby driving each magnetic system vehicle 122 fixed on the conveyor belt 124 to move along the annular fixing frame 123. The pulley 1211 is matched with the annular track 1231 to improve the stability of the magnetic system vehicle 122, making it move more smoothly and preventing the components in the magnetic system vehicle 122 from being displaced and affecting assembly. When the magnetic system vehicle 122 moves to the corresponding mechanism position, the first positioning mechanism 111 operates to position the magnetic system vehicle 122. If there is no obstacle during the sliding of the positioning member, it means that the position of the magnetic system vehicle 122 is accurate. If there is an obstruction during the rising process of the positioning member, it means that the current position of the magnetic system vehicle 122 is deviated and assembly cannot be completed.

The iron core is cylindrical, and one end is provided with a "D"-shaped flange including a straight side surface and a circular surface. The iron core is fed through the iron core feeding channel 161 and is in a vertical state and enters the second accommodating cavity 1651. Then, it is clamped into the third accommodating cavity 16411 by the second clamping member 1632. The tenth driving member 1642 drives the rotation of the second rotating base 1641. When the straight side surface of the iron core faces the direction of the first rotating base 1621, the rotation stops. The third clamping member 1633 clamps the iron core into the first accommodating cavity.
