Description

Technical Field

[0001] The utility model relates to assembly equipment, in particular to an assembly equipment for an internal magnetic system of a circuit breaker. Background Art

[0002] The magnetic system is a component used to be installed in a circuit breaker. When the current transformer detects an abnormal current, it impacts the free tripping module in the circuit breaker to achieve tripping. The existing magnetic system includes an iron core, a coil, a static contact, a wiring board, and a wiring terminal. The coil is sleeved on the iron core. One end of the coil is connected to the static contact, and the other end is connected to one end of the wiring board. The wiring terminal is sleeved on the other end of the wiring board. The wiring terminal includes a rectangular frame body and a screw threadedly engaged with the frame body. The frame body is provided with a threaded hole adapted to the screw.

[0003] At present, the assembly of the internal magnetic system of the circuit breaker can adopt manual, semi-automatic, and full-automatic methods, etc. Most of the current assembly methods are to first weld the two ends of the coil to the static contact and the wiring board to form a contact support, and then through several feeding mechanisms, the contact support, the iron core, and the wiring terminal assembly are respectively fed and assembled on the carrier to form the magnetic system, and the magnetic system is clamped into the circuit breaker housing by a clamping member.

[0004] Specifically, the existing assembly equipment includes a disc and various feeding mechanisms and discharging mechanisms sequentially arranged around the circumference of the disc. The disc is provided with several carriers. The disc rotates driven by a motor, driving the carriers to sequentially pass through various feeding mechanisms and discharging mechanisms. Each component is placed into the carrier by the feeding mechanism to complete the assembly, and then the assembled magnetic system is placed into an empty circuit breaker housing by a clamping member, and finally discharged. However, for the existing assembly equipment, since the disc drives the carrier, only single assembly can be performed during assembly, resulting in low assembly efficiency and low practicability. Content of the Utility Model

[0005] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides an assembly equipment for an internal magnetic system of a circuit breaker, which uses an annular conveyor belt to convey the carriers, and each mechanism is arranged around the ring, and can assemble multiple magnetic systems synchronously, with high assembly efficiency and improved practicability of the equipment.

[0006] Technical solution of the utility model: An assembly device for an internal magnetic system of a circuit breaker, comprising a frame, on which a first carrier loop, a circuit breaker housing feeding mechanism and a finished product discharging mechanism are provided. A plurality of carrier toolings are provided on the first carrier loop, and at least two magnetic system carriers are provided on each carrier tooling. A contact support feeding mechanism, an iron core feeding mechanism, a terminal feeding mechanism, a screw tightening mechanism and a magnetic system housing installation mechanism are provided on the frame outside the first carrier loop. The magnetic system housing installation mechanism is located between the circuit breaker housing feeding mechanism and the first carrier loop, and the magnetic system housing installation mechanism picks up the magnetic system in the magnetic system carrier and installs it into the circuit breaker housing on the circuit breaker housing feeding mechanism.

[0007] With the above technical solution, the magnetic system carrier is moved through the first carrier loop, and components are assembled into the magnetic system carrier through each feeding mechanism. Then, the assembled magnetic system is sent into the circuit breaker housing through the magnetic system housing installation mechanism to complete the assembly of the finished product. At least two magnetic system carriers are provided on each carrier tooling, and multiple magnetic system assemblies can be carried out simultaneously, improving the assembly efficiency. Moreover, the movement route of the magnetic system carrier is circularly arranged, and each mechanism is arranged along the first carrier loop. Additionally, multiple iron core feeding mechanisms, terminal feeding mechanisms, screw tightening mechanisms and magnetic system housing installation mechanisms can be provided to perform multiple feeding and housing installations simultaneously, and the layout of each mechanism is reasonable.

[0008] Further setting of the utility model: A contact support placement groove, an iron core placement groove and a terminal placement groove are provided on the magnetic system carrier. The contact support feeding mechanism includes a contact support feeding tray, a vision sensor and a contact support feeding part for conveying the contact support in the contact support feeding tray into the contact support placement groove. The vision sensor is located above the contact support feeding tray. There are two iron core feeding mechanisms, each including an iron core feeding channel, a first rotating component for rotating the iron core from a vertical state to a horizontal state, and an iron core feeding part for conveying the rotated iron core into the iron core placement groove. The terminal feeding mechanism includes a terminal feeding component and a terminal feeding part for conveying the terminal into the terminal placement groove. The screw tightening mechanism includes a rotating shaft and a first driving part for driving the rotating shaft to rotate. The magnetic system housing installation mechanism includes a picking part and a driving component for driving the picking part to convey the magnetic system in the magnetic system carrier into the circuit breaker housing.

[0009] With the above further settings, the corresponding components are conveyed into the placement slots in the magnetic system carrier by each feeding mechanism for the assembly of the magnetic system. After assembly, the magnetic system is clamped into the circuit breaker housing by the picking part to form a finished product. Finally, the finished product is discharged by the finished product discharging mechanism, and the finished product discharging includes the discharging of qualified products and unqualified products. A visual sensing device is arranged on the front side of the discharging mechanism for detection to ensure the qualified rate of the products. Before the contact support is placed into the contact support placement slot, it is captured by the visual sensor first, so that the orientations of the contact supports are the same after feeding, ensuring the accuracy of the assembly.

[0010] A further setting of the present utility model: The first carrier loop includes an annular fixing frame, a conveyor belt, a motor for driving the conveyor belt to work, and a conveyor pulley group. The motor is fixedly arranged on the annular fixing frame. Each carrier tooling is fixedly arranged on the outer side wall of the conveyor belt. An annular track is arranged on the annular fixing frame on the outer side of the conveyor belt. A pulley is arranged on the lower end surface of each carrier tooling, and each pulley is in sliding fit with the annular track.

[0011] With the above further setting, the motor drives the conveyor belt to move through the conveyor pulley group, thereby driving each magnetic system carrier fixed on the conveyor belt to move along the annular fixing frame. The pulley is matched with the annular track to improve the stability of the magnetic system carrier, making it move more smoothly and preventing the components in the magnetic system carrier from being displaced and affecting the assembly.

[0012] A further further setting of the present utility model: A positioning mechanism is further arranged on the frame. The positioning mechanism includes a first positioning component and a second positioning component. There are two groups of each positioning component. The two first positioning components are respectively located on both sides of the conveyor belt. The two first positioning components both include a mounting plate, a plurality of first positioning parts, and a second driving part for driving the mounting plate to lift. Each first positioning part is fixedly arranged on the mounting plate. The two second positioning components are respectively located at both ends of the conveyor belt. The two second positioning components both include a second positioning part and a third driving part for driving the second positioning part to lift. Through slots are opened on the annular fixing frame corresponding to the positions of each first positioning part and each second positioning part. The positioning parts are slidably arranged in the corresponding through slots, and a positioning slot for inserting the carrier tooling is opened at the upper end of the positioning part.

[0013] With the above further further setting, when the magnetic system carrier moves to the corresponding mechanism position, the positioning mechanism works to position the magnetic system carrier. If there is no obstacle when the positioning part slides, it means that the position of the magnetic system carrier is accurate. If there is an obstacle during the rising process of the positioning part, it means that the current position of the magnetic system carrier is deviated and the assembly cannot be completed.

[0014] A further improvement of the present utility model: The magnetic system housing installation mechanism further includes a magnetic system installation channel, which is located between the circuit breaker housing feeding mechanism and the finished product discharging mechanism.

Two picking members are arranged along the magnetic system installation channel, and the installation of two magnetic systems into the housing can be completed simultaneously, with higher efficiency and a reasonable overall structural layout.

[0016] A further improvement of the present utility model: A first handling fork, a fourth driving member for driving the first handling fork to move along the X-axis direction of the magnetic system installation channel, and a fifth driving member for driving the first handling fork to move along the Y-axis direction of the magnetic system installation channel are further provided on the frame. The first handling fork is located on the side of the magnetic system installation channel away from the picking member, and a number of clamping grooves matching the circuit breaker housing are provided on the first handling fork.

[0017] With the above further improvement, a column is provided on the circuit breaker housing, and the clamping groove cooperates with the column. The movement of the circuit breaker housing in the magnetic system installation channel is realized through the first handling fork, and it moves sequentially from the circuit breaker housing feeding mechanism to the finished product discharging mechanism direction. During the magnetic system assembly, the stability is good, the position is accurate, it corresponds to each mechanism, and there is no deviation during assembly.

[0018] A further improvement of the present utility model: The first rotating assembly includes a first rotating base and a sixth driving member for driving the first rotating base to rotate. The sixth driving member is horizontally arranged, and the first rotating base is arranged on the output shaft of the sixth driving member. A first accommodating cavity for accommodating the iron core is provided on the rotating base. The iron core feeding mechanism further includes a second rotating assembly, a conveying base, and a seventh driving member for driving the conveying base to slide horizontally. The conveying base is located below the iron core feeding channel, and a second accommodating cavity for accommodating the iron core is provided on the conveying base. The second rotating assembly includes a second rotating base, an eighth driving member for driving the second rotating base to rotate, and sensors located at both ends of the second rotating base.

[0019] With the above further improvement, the iron core is cylindrical, and a "5"-shaped flange including a straight edge surface and a circular surface is provided at one end. The iron core is fed through the iron core feeding channel and is in a vertical state. It enters the second accommodating cavity, and then is clamped into the third accommodating cavity by the second clamping member. The eighth driving member drives the second rotating base to rotate. When the straight edge surface of the iron core faces the direction of the first rotating base, the rotation stops. The third clamping member clamps the iron core into the first accommodating cavity. The first rotating base rotates 90°, and the iron core changes from a vertical state to a horizontal setting. The first clamping member clamps the iron core into the iron core placement groove, and the coil on the contact support is sleeved outside the iron core, completing the feeding of the iron core, making the feeding position of each iron core accurate and the orientation consistent.

[0045] Such as Figure 1-20As shown in the figure, an assembly device for the internal magnetic system of a circuit breaker includes a frame 1. On the frame 1, there are a first carrier loop 2, a circuit breaker housing feeding mechanism 3, and a finished product discharging mechanism 4. On the first carrier loop 2, there are several carrier toolings 21, and each carrier tooling 21 is provided with at least two magnetic system carriers 22. On the frame 1, outside the first carrier loop 2, there are a contact support feeding mechanism 5, an iron core feeding mechanism 6, a terminal feeding mechanism 7, a screw tightening mechanism 8, and a magnetic system housing installation mechanism 9. The magnetic system housing installation mechanism 9 is located between the circuit breaker housing feeding mechanism 3 and the first carrier loop 2. The magnetic system housing installation mechanism 9 picks up the magnetic system in the magnetic system carrier 22 and installs it into the circuit breaker housing on the circuit breaker housing feeding mechanism 3. By moving the magnetic system carrier 22 through the first carrier loop 2, components are assembled into the magnetic system carrier 22 through each feeding mechanism, and then the assembled magnetic system is sent into the circuit breaker housing through the magnetic system housing installation mechanism 9 to complete the assembly of the finished product. Each carrier tooling 21 is provided with at least two magnetic system carriers 22, and multiple magnetic system assemblies can be carried out simultaneously to improve the assembly efficiency. Moreover, the movement route of the magnetic system carrier 22 is arranged in a ring shape, and each mechanism is arranged along the first carrier loop. Additionally, multiple iron core feeding mechanisms 6, terminal feeding mechanisms 7, screw tightening mechanisms 8, magnetic system housing installation mechanisms 9, etc. can be provided to perform multiple feeding and housing installations simultaneously, and the layout of each mechanism is reasonable. There is also a control device on the frame 1, and each driving part and motor are controlled by the control device. The information collected by the vision sensor 52 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 utility model; therefore, no further specific description will be given.

[0046] Specifically, each magnetic system carrier 22 is provided with a contact bracket placement groove 221, an iron core placement groove 222, and a terminal placement groove 223. The contact bracket feeding mechanism 5 includes a contact bracket feeding tray 51, a vision sensor 52, and a contact bracket feeding member 53 for conveying the contact brackets in the contact bracket feeding tray 51 into the contact bracket placement groove 221.

The vibrating disk 11 is arranged on one side of the contact bracket feeding tray 51, and the discharge port of the vibrating disk 11 is higher than the contact bracket feeding tray 51. The contact brackets are located in the vibrating disk 11 and fall into the contact bracket feeding tray 51 one by one through the vibration of the vibrating disk 11. The contact bracket feeding mechanism 5 further includes a drive motor assembly 54 for driving the contact bracket feeding member 53 to rotate. The vision sensor 52 transmits the image collected from the contact bracket feeding tray 51 to the control device, and the control device outputs a signal to control the operation of the drive motor assembly 54, driving the contact bracket feeding member 53 to rotate and adjust the orientation of the contact brackets so that the contact brackets face the same direction when being fed. There are two iron core feeding mechanisms 6, both of which include an iron core feeding channel 61, a first rotating assembly 62 for rotating the iron core from a vertical state to a horizontal state, and an iron core feeding member 63 for conveying the rotated iron core into the iron core placement groove 222. The iron core feeding channel is connected to an iron core storage barrel. A staircase is provided on the frame for facilitating the storage of the iron cores.

The magnetic system can be directly clamped and placed into the circuit breaker housing in one step by the picking member 91, or a buffer area can be set on the frame 1 and it is clamped in two steps. First, the magnetic system in the carrier is clamped to the buffer area, and then it is clamped from the buffer area into the circuit breaker housing. Through each feeding mechanism, the corresponding components are conveyed into the placement grooves in the magnetic system carrier 22 for the assembly of the magnetic system. After assembly, the magnetic system is clamped by the picking member 91 into the circuit breaker housing to form a finished product, and finally it is discharged through the finished product discharging mechanism 4. And the finished product discharging includes discharging of qualified products and unqualified products. A vision sensing device 10 is arranged in front of the discharging mechanism for detection to ensure the qualification rate of the products. Before the contact brackets are placed into the contact bracket placement groove 221, they are first captured by the vision sensor 52 to make the contact brackets face the same direction after being fed, ensuring the accuracy of assembly.In the present utility model, the contact support feeding member, the iron core feeding member, the terminal feeding member, the picking member, the breaker housing feeding member, and the finished product discharging member can all move along the X-axis, Y-axis, and Z-axis directions of the frame under the drive of the cylinder, and can be matched by guide rails and guide grooves. The specific structure belongs to the prior art, so it will not be elaborated herein.

[0047] The first carrier loop 2 includes an annular fixing frame 23, a conveyor belt 24, and a motor and a conveyor pulley group for driving the conveyor belt 24 to work. The motor is fixedly arranged on the annular fixing frame 23, and each carrier tooling 21 is fixedly arranged on the outer side wall of the conveyor belt 24. An annular track 231 is arranged on the annular fixing frame 23 outside the conveyor belt 24. A pulley 224 is arranged on the lower end surface of each carrier tooling 21, and each pulley 224 is slidably matched with the annular track 231. At least one pulley 224 is arranged on both the inner and outer sides of the annular track 231. A groove is arranged on the pulley 224, and a convex edge is arranged on the annular track 231. The convex edge is located in the groove. The motor drives the conveyor belt 24 to move through the conveyor pulley group, so as to drive each magnetic system carrier 22 fixed on the conveyor belt 24 to move along the annular fixing frame 23. The pulley 224 is matched with the annular track 231 to improve the stability of the magnetic system carrier 22, making the movement more stable and avoiding the displacement of the components in the magnetic system carrier 22 from affecting the assembly. A positioning mechanism 20 is further arranged on the frame 1. The positioning mechanism 20 includes a first positioning component 201 and a second positioning component 202.

The guide grooves are matched with the guide rail to play a guiding role, and the structural stability is good during sliding. Through grooves 232 are arranged on the annular fixing frame 23 corresponding to the positions of each first positioning member 2012 and each second positioning member 2021. The positioning members are slidably arranged in the corresponding through grooves 232, and a positioning notch for inserting the carrier tooling 21 is arranged at the upper end of the positioning member. When the magnetic system carrier 22 moves to the corresponding mechanism position, the positioning mechanism 20 works to position the magnetic system carrier 22. If there is no obstacle when the positioning member slides, it means that the position of the magnetic system carrier 22 is accurate. If there is an obstacle during the rising process of the positioning member, it means that the current position of the magnetic system carrier 22 is deviated and the assembly cannot be completed.

The movement of the circuit breaker housing in the magnetic system installation channel 93 is realized through the first handling fork 12, and it moves sequentially from the circuit breaker housing feeding mechanism 3 to the finished product discharging mechanism 4. During magnetic system assembly, the stability is good, the position is accurate, corresponding to each mechanism, and there is no deviation during assembly.
