Description

Technical Field

[0001] This utility model relates to the technical field of circuit breaker processing equipment, and in particular to an automatic assembly device for the arc-extinguishing chamber of a molded case circuit breaker. Background Technology

[0002] A circuit breaker is a protective switch for branch circuits, housing contacts, an arc-extinguishing chamber, a trip unit, and an operating mechanism within a plastic casing. During assembly, arc-extinguishing plates need to be installed into the arc-extinguishing chamber of the circuit breaker casing. These arc-extinguishing plates include paper arc-extinguishing plates and epoxy arc-extinguishing plates. In assembly, the epoxy arc-extinguishing plate is first placed inside the arc-extinguishing chamber, and then the paper arc-extinguishing plate is placed on top of it. Currently, the arc-extinguishing chamber is usually assembled manually. This method has several drawbacks: First, it has low assembly efficiency, making it difficult to meet the needs of mass production; second, because the paper arc-extinguishing plate is made of paper, it is prone to deformation during assembly, which may increase the defect rate of the assembled circuit breakers; third, manual assembly is prone to incomplete assembly of the arc-extinguishing plate, thus affecting the quality of the circuit breaker. Summary of the Invention

The device comprises two rotary motors, a second vibrating track connected to the equipment base, a third fixed frame connected to the equipment base, a fifth sliding base slidably connected to the third fixed frame, a sixth sliding base slidably connected to the fifth sliding base, a fourth electric clamping claw connected to the sixth sliding base, a sixth hydraulic cylinder for driving the fifth sliding base to move horizontally, and a seventh hydraulic cylinder for driving the sixth sliding base to move vertically. The movement trajectory of the fourth electric clamping claw passes directly above the second vibrating track and the second feeding platform. The circuit breaker feeding device includes a fourth fixed frame connected to the equipment base, a fifth sliding base slidably connected to the third fixed frame, a sixth sliding base slidably connected to the third fixed frame, a sixth sliding base slidably connected to the fifth sliding base, a sixth electric clamping claw connected to the sixth sliding base, a sixth hydraulic cylinder for driving the fifth sliding base to move horizontally, and a seventh hydraulic cylinder for driving the sixth sliding base to move vertically. The fourth fixed frame includes a seventh sliding base, an eighth sliding base slidably connected to the seventh sliding base, a fifth electric clamping jaw movably connected to the eighth sliding base, a third rotary motor for driving the fifth electric clamping jaw to rotate, an eighth hydraulic cylinder for driving the seventh sliding base to move horizontally, a ninth hydraulic cylinder for driving the eighth sliding base to move vertically, a third conveyor belt connected to the equipment base, and a fourth drive motor for driving the third conveyor belt. The movement trajectory of the fifth electric clamping jaw passes directly above the first feeding platform and the third conveyor belt. The controller is connected to the first feeding group. The system includes a component, a second feeding assembly, a first hydraulic cylinder, a second hydraulic cylinder, a third hydraulic cylinder, a fourth hydraulic cylinder, a fifth hydraulic cylinder, a sixth hydraulic cylinder, a seventh hydraulic cylinder, an eighth hydraulic cylinder, a ninth hydraulic cylinder, a sixteenth hydraulic cylinder, a seventeenth hydraulic cylinder, a first drive motor, a second drive motor, a third drive motor, a fourth drive motor, a first electric clamping jaw, a second electric clamping jaw, a third electric clamping jaw, a fourth electric clamping jaw, a fifth electric clamping jaw, a sixth electric clamping jaw, a first rotary motor, a second rotary motor, a third rotary motor, a fourth rotary motor, a vibration motor, and an electrically connected CCD vision inspection instrument.

[0005] Using the above technical solution, firstly, the circuit breaker to be processed is placed on the third conveyor belt. Then, the controller controls the fourth drive motor to move the third conveyor belt, thereby moving the circuit breaker to directly below the fifth electric clamping claw. Then, the ninth hydraulic cylinder drives the eighth sliding base to move vertically downwards, and the fifth electric clamping claw clamps the circuit breaker. The controller then controls the eighth and ninth hydraulic cylinders to move the seventh and eighth sliding bases respectively, so that the position of the fifth electric clamping claw is aligned with the first feeding platform. Then, the circuit breaker is placed on the first feeding platform, and the first feeding assembly moves the circuit breaker a certain distance. At the same time, the epoxy arc-shielding plate is fed to the first flat vibrating track by a rotating vibrating feed plate. When the epoxy arc breaker plate moves to the end of the first vibration track, the controller controls the third and fourth hydraulic cylinders to drive the third and fourth sliding bases to move respectively. Then, the second electric clamping jaws clamp the epoxy arc breaker plate and place it on the second feeding platform. The controller then drives the second transmission belt via the second drive motor, which in turn moves the paper arc breaker plate through the guide plate into the vibration tray. First, a CCD vision inspection device takes a real-time image of the paper arc breaker plate on the vibration tray and compares it with the standard state paper arc breaker plate. If the paper arc breaker plate is found to be facing upwards with the correct clamping surface, the CCD vision inspection device calculates the angle difference between it and the standard state, as well as the coordinate position of the circuit breaker. Then, the controller... The third drive motor moves the robotic arm a certain distance, positioning the third electric gripper directly above the circuit breaker. The fifth hydraulic cylinder moves the connecting plate vertically, and the second rotary motor rotates the third electric gripper at a certain angle, aligning it with and clamping the paper arc-breaking plate. The third drive motor then moves the robotic arm, transferring the paper arc-breaking plate to the second vibrating track. The second vibrating track continues to feed the paper arc-breaking plate. For any remaining incorrectly oriented paper arc-breaking plates on the vibrating tray, the controller activates the vibration motor, causing the paper arc-breaking plate to bounce on the tray until it is stopped by C. After the CD vision inspection instrument detects that the orientation is correct, the clamping process continues. Then, the controller controls the sixth and seventh hydraulic cylinders to drive the fifth and sixth sliding bases to move, respectively. The fourth electric clamping claw then picks up the paper arc-extinguishing plate and places it on the second feeding platform, stacking it together with the epoxy arc-extinguishing plate, completing the first step of the arc-extinguishing plate assembly. Next, the controller controls the sixteenth and seventeenth hydraulic cylinders to drive the fifteenth and sixteenth sliding bases to slide a certain distance, respectively. Then, the fourth rotary motor drives the connecting block to rotate 90 degrees, causing the sixth electric clamping claw to clamp the assembled paper arc-extinguishing plate and epoxy arc-extinguishing plate together and bring them to the circuit breaker located on the first feeding platform, where they are installed into the arc-extinguishing chamber of the circuit breaker.Then, the first feeding component of the controller drives the assembled circuit breaker to continue moving a certain distance. Next, the first and second hydraulic cylinders respectively drive the first and second sliding bases to move a certain distance. The first electric clamping claw then transfers the assembled circuit breaker from the first feeding platform to the first conveyor belt, where it is unloaded. Compared to traditional circuit breaker arc-extinguishing chamber assembly methods, this device significantly improves automation. Furthermore, the paper arc-extinguishing plate is fed using a flexible feeding method, which avoids deformation during feeding and assembly, thus improving the quality of the assembled circuit breaker.

[0006] Further features of this invention: The first feeding assembly includes a sixth fixed frame connected to the bottom of the first feeding platform, a ninth sliding base slidably connected to the sixth fixed frame, a tenth sliding base slidably connected to the ninth sliding base, a tenth hydraulic cylinder for driving the ninth sliding base to move horizontally, and an eleventh hydraulic cylinder for driving the tenth sliding base to move vertically. The first feeding platform is provided with a first fixing groove, the shape and size of which are adapted to the cross-sectional shape of the tenth sliding base. The tenth sliding base is provided with a plurality of first positioning grooves, the width of which is adapted to the width of the circuit breaker housing to be processed. The second feeding assembly includes a sixth fixed frame connected to the bottom of the first feeding platform, a ninth sliding base slidably connected to the sixth fixed frame, a tenth sliding base slidably connected to the ninth sliding base, a tenth hydraulic cylinder for driving the ninth sliding base to move horizontally, and an eleventh hydraulic cylinder for driving the tenth sliding base to move vertically. The second feeding platform includes a seventh fixed frame at the bottom, an eleventh sliding base slidably connected to the seventh fixed frame, a twelfth sliding base slidably connected to the eleventh sliding base, a twelfth hydraulic cylinder for driving the eleventh sliding base to move horizontally, and a thirteenth hydraulic cylinder for driving the twelfth sliding base to move vertically. The second feeding platform is provided with a second fixed groove, the second fixed groove being adapted to the cross-sectional shape and size of the twelfth sliding base. The twelfth sliding base is provided with several second positioning grooves, the second positioning grooves being adapted to the cross-sectional shape and size of the paper arc-breaking plate to be processed. The controller is electrically connected to the tenth, eleventh, twelfth, and thirteenth hydraulic cylinders respectively.

[0007] Using the above technical solution, when the circuit breaker is fed to the first feeding platform, it needs to be placed in the first fixed groove and corresponding to the first positioning groove. Then, the controller controls the eleventh hydraulic cylinder to drive the tenth sliding base to move vertically upward, so that the circuit breaker is positioned in the first positioning groove. Then, the tenth hydraulic cylinder drives the ninth sliding base to slide a certain distance in the horizontal direction, thereby driving the circuit breaker to complete the movement. Similarly, the paper arc breaker and the epoxy arc breaker are assembled together and fed on the second feeding platform by the second feeding assembly. This can greatly improve the stroke accuracy of the circuit breaker, paper arc breaker and epoxy arc breaker during the feeding process, thereby improving the assembly accuracy.

[0008] A further feature of this invention includes a detection device comprising a tenth fixed frame connected to the equipment base, a thirteenth sliding base slidably connected to the tenth fixed frame, a plurality of probes slidably connected to the thirteenth sliding base, a plurality of first photoelectric sensors connected to the thirteenth sliding base, a plurality of second photoelectric sensors connected to the equipment base, and a fourteenth hydraulic cylinder for driving the thirteenth sliding base to move vertically. The number of first photoelectric sensors is the same as the number of probes. The positions of the photoelectric signals emitted by the first photoelectric sensors correspond one-to-one with the positions of the probes. The positions of the photoelectric signals emitted by the second photoelectric sensors correspond to the positions directly below the first, second, third, fourth, and fifth electric clamping jaws. The thirteenth sliding base is located directly above the first feeding platform. When the circuit breaker passes directly below the thirteenth sliding base, the position of the probe corresponds to the position of the arc-extinguishing chamber inside the circuit breaker. The controller is electrically connected to the fourteenth hydraulic cylinder, the first photoelectric sensors, and the second photoelectric sensors.

[0009] Using the above technical solution, when the circuit breaker moves from one end of the first feeding platform to the other, it will first pass directly below the probe. The controller controls the fourteenth hydraulic cylinder to drive the thirteenth sliding base to move vertically downward, thereby driving the probe downward. If there is no assembly error, foreign object in the arc-extinguishing chamber, or incorrect placement of the circuit breaker during feeding, the probe can slide down smoothly without obstruction. Otherwise, if some probes are obstructed, they will be subjected to a reaction force and move vertically upward. The first photoelectric sensor will detect this and send an electrical signal to the controller, which will report an error. In addition, since the positions of the photoelectric signals emitted by the second photoelectric sensor correspond to the positions directly below the first, second, third, fourth, and fifth electric clamping claws, the accurate feeding positions of each component can be ensured during assembly, thereby further improving assembly accuracy and increasing the product qualification rate.

[0010] A further feature of this invention is the inclusion of an arc-extinguishing chamber clamping device. This device comprises an eighth fixed frame fixedly connected to the equipment base, a fourteenth sliding base slidably connected to the eighth fixed frame, several push rods connected to the fourteenth sliding base, a fifteenth hydraulic cylinder for driving the fourteenth sliding base to move vertically, and a third photoelectric sensor connected to the equipment base. The position of the third photoelectric sensor corresponds to the area directly below the fourteenth sliding base. When the circuit breaker is located directly below the fourteenth sliding base, the position of the push rods corresponds to the position of the arc-extinguishing chamber in the circuit breaker.

[0011] Using the above technical solution, when the assembled circuit breaker moves to directly below the top rod via the first conveyor belt, the controller controls the fifteenth hydraulic cylinder to drive the fourteenth sliding base to move vertically downward, thereby driving the top rod to press down and apply a certain pressure to the paper arc breaker and epoxy arc breaker on the circuit breaker, further ensuring that the two types of arc breaker can be assembled in place, thereby further improving the product qualification rate.

The hydraulic cylinders 14, 15, 36, 37, 48, 55, 56, 62, 63, 25, and 26; 1, 39, 45, and 65; 12, 33, 47, 54; 54, 60, and 24; 24; 13; 49; 61; 27; 43; 43; 54; 60; 24; 24; 13; 49; 61; 27; 43; 43; 44; 55; 65; 65; 66; 67; 64; 65; 65; 66; 67; 68; 69; 60; 61; 64; 65; 65; 65; 66; 67; 68; 69; 61; 62; 63; 64; 65; 65; 66; 67; 64; 65; 65; 66; 67; 68; 69; 61; 61; 62; 63; 64; 65; 65; 66; 67; 64; 65; 65; 66; 67; 64; 65; 65; 66; 67; 64; 65; 65; 66; 67; 68; 69; 61; 61; 62; 63 ...

[0023] First, the circuit breaker to be processed is placed on the third conveyor belt 64. Then, the controller 6 controls the fourth drive motor 65 to move the third conveyor belt 64, thereby moving the circuit breaker to directly below the fifth electric clamping jaw 60. Then, the ninth hydraulic cylinder 63 drives the eighth sliding base 59 to move vertically downwards, and the fifth electric clamping jaw 60 clamps the circuit breaker. Next, the controller 6 controls the eighth hydraulic cylinder 62 and the ninth hydraulic cylinder 63 to move the seventh sliding base 58 and the eighth sliding base 59 respectively, so that the position of the fifth electric clamping jaw 60 is aligned with the first feeding platform 16. Then, the circuit breaker is placed on the first feeding platform 16, and the first feeding assembly 17 drives the circuit breaker to move a certain distance. Simultaneously, the epoxy arc-isolating plate is fed to the first flat vibrating track 29 by rotating the vibrating feed plate 28. When the epoxy arc-isolating plate moves to the end of the first flat vibrating track 29, the controller 6 controls the third hydraulic cylinder 36 and the fourth hydraulic cylinder 37 to drive the third sliding base 31 and the fourth sliding base 32 to move respectively. Then, the second electric clamping claw 33 clamps the epoxy arc-isolating plate and places it on the second feeding platform 34. Then, the controller 6 drives the second transmission belt 38 to move by the second drive motor 39, thereby moving the paper arc-isolating plate through the guide plate 40 to the flat vibrating tray 42. First, the CCD vision inspection instrument 41 takes real-time image information of the paper arc-isolating plate on the flat vibrating tray 42 and compares it with the standard state paper arc-isolating plate. By comparing the plates, if the paper arc-breaking plate is found to be correctly clamped with its clamping surface facing upwards, the CDD vision inspection instrument calculates the angle difference between it and the standard state, as well as the coordinate position of the circuit breaker. Then, the controller 6 controls the third drive motor 45 to move the robotic arm 44 a certain distance, so that the position of the third electric clamping jaw 47 is directly above the circuit breaker. The fifth hydraulic cylinder 48 drives the connecting plate 46 to move vertically, and the second rotary motor 49 drives the third electric clamping jaw 47 to rotate a certain angle, so that the third electric clamping jaw 47 corresponds to the position of the paper arc-breaking plate and clamps it. Then, the third drive motor 45 drives the robotic arm 44 to move, so that the third electric clamping jaw 47 clamps the paper arc-breaking plate. The paper arc-breaking plate is transferred to the second transducer track 50, which then continues to feed the paper arc-breaking plate. For any remaining paper arc-breaking plates on the transducer tray 42 that are not oriented correctly, the controller 6 controls the vibration motor 43 to operate, causing the paper arc-breaking plate to bounce on the transducer tray 42 until the paper arc-breaking plate is detected by the CCD vision inspection instrument 41 to be oriented correctly. Then, the clamping work continues. The controller 6 then controls the sixth hydraulic cylinder 55 and the seventh hydraulic cylinder 56 to drive the fifth sliding base 52 and the sixth sliding base 53 to move, respectively. The fourth electric clamping claw 54 then clamps the paper arc-breaking plate onto the second feeding platform 34 and stacks it together with the epoxy arc-breaking plate, completing the first step of the arc-breaking plate assembly work.Then, the controller 6 controls the sixteenth hydraulic cylinder 25 and the seventeenth hydraulic cylinder 26 to drive the fifteenth sliding base 21 and the sixteenth sliding base 22 to slide a certain distance, respectively. Then, the fourth rotary motor 27 drives the connecting block 23 to rotate 90 degrees, so that the sixth electric clamping claw 24 clamps the assembled paper arc-extinguishing plate and epoxy arc-extinguishing plate together and brings them to the circuit breaker located above the first feeding platform 16, and puts them into the arc-extinguishing chamber of the circuit breaker. Then, the controller 6 controls the first feeding assembly 17 to drive the assembled circuit breaker to continue moving a certain distance. The assembly process involves moving the first sliding base 10 and the second sliding base 11 a certain distance via the first hydraulic cylinder 14 and the second hydraulic cylinder 15, respectively. The assembled circuit breaker is then transferred from the first feeding platform 16 to the first conveyor belt 7 via the first electric clamping claw 12, where it is unloaded. Compared to traditional circuit breaker arc-extinguishing chamber assembly methods, this device significantly improves automation. Furthermore, the flexible feeding method for the paper arc-extinguishing plate prevents deformation during feeding and assembly, thus improving the quality of the assembled circuit breaker.

[0024] The first feeding assembly 17 includes a sixth fixed frame 66 connected to the bottom of the first feeding platform 16, a ninth sliding base 67 slidably connected to the sixth fixed frame 66, a tenth sliding base 68 slidably connected to the ninth sliding base 67, a tenth hydraulic cylinder 69 for driving the ninth sliding base 67 to move horizontally, and an eleventh hydraulic cylinder 70 for driving the tenth sliding base 68 to move vertically. The first feeding platform 16 is provided with a first fixing groove 71, the shape and size of which are adapted to the cross-sectional shape of the tenth sliding base 68. The tenth sliding base 68 is provided with a plurality of first positioning grooves 72, the width of which is adapted to the width of the circuit breaker housing to be processed. The second feeding assembly 35 includes a sixth fixed frame 66 connected to the bottom of the second feeding platform 34. The system includes a seventh fixed frame 73, an eleventh sliding base 74 slidably connected to the seventh fixed frame 73, a twelfth sliding base 75 slidably connected to the eleventh sliding base 74, a twelfth hydraulic cylinder 76 for driving the eleventh sliding base 74 to move horizontally, and a thirteenth hydraulic cylinder 77 for driving the twelfth sliding base 75 to move vertically. The second feeding platform 34 is provided with a second fixing groove 78, which is adapted to the cross-sectional shape and size of the twelfth sliding base 75. The twelfth sliding base 75 is provided with a plurality of second positioning grooves 79, which are adapted to the cross-sectional shape and size of the paper arc-breaking plate to be processed. The controller 6 is electrically connected to the tenth hydraulic cylinder 69, the eleventh hydraulic cylinder 70, the twelfth hydraulic cylinder 76, and the thirteenth hydraulic cylinder 77, respectively.

[0025] When the circuit breaker is fed to the first feeding platform 16, it needs to be placed in the first fixed groove 71 and the position corresponding to the first positioning groove 72. Then, the controller 6 controls the eleventh hydraulic cylinder 70 to drive the tenth sliding base 68 to move vertically upward, so that the circuit breaker is positioned in the first positioning groove 72. Then, the tenth hydraulic cylinder 69 drives the ninth sliding base 67 to slide a certain distance in the horizontal direction, thereby driving the circuit breaker to complete the movement. Similarly, the paper arc breaker and the epoxy arc breaker are assembled together and fed on the second feeding platform 34 by the second feeding assembly 35. This can greatly improve the stroke accuracy of the circuit breaker, paper arc breaker and epoxy arc breaker during the feeding process, thereby improving the assembly accuracy.

[0026] It also includes a detection device 80, which comprises a tenth fixed frame 81 connected to the equipment base 1, a thirteenth sliding base 82 slidably connected to the tenth fixed frame 81, a plurality of probes 83 slidably connected to the thirteenth sliding base 82, a plurality of first photoelectric sensors 84 connected to the thirteenth sliding base 82, a plurality of second photoelectric sensors 85 connected to the equipment base 1, and a fourteenth hydraulic cylinder 86 for driving the thirteenth sliding base 82 to move vertically. The number of first photoelectric sensors 84 is the same as the number of probes 83, and the positions of the photoelectric signals emitted by the first photoelectric sensors 84 are respectively relative to the probes 83. The positions of the three are in one-to-one correspondence. The positions of the photoelectric signals emitted by the second photoelectric sensor 85 correspond to the positions directly below the first electric clamping jaw 12, the second electric clamping jaw 33, the third electric clamping jaw 47, the fourth electric clamping jaw 54, and the fifth electric clamping jaw 60. The thirteenth sliding base 82 is located directly above the first feeding platform 16. When the circuit breaker passes directly below the thirteenth sliding base 82, the position of the probe 83 corresponds to the position of the arc-extinguishing chamber inside the circuit breaker. The controller 6 is electrically connected to the fourteenth hydraulic cylinder 86, the first photoelectric sensor 84, and the second photoelectric sensor 85.

[0027] As the circuit breaker moves from one end of the first feeding platform 16 to the other, it first passes directly below the probe 83. The controller 6 controls the fourteenth hydraulic cylinder 86 to drive the thirteenth sliding base 82 to move vertically downward, thereby driving the probe 83 downward. If there are no assembly errors, foreign objects in the arc-extinguishing chamber, or incorrect placement of the circuit breaker during loading, the probe 83 can slide down smoothly without obstruction. Otherwise, if some probes 83 are obstructed, they will be subjected to a reaction force and move vertically upward. The first photoelectric sensor 84 will sense this and send an electrical signal to the controller 6, which will then report an error. Furthermore, since the positions of the photoelectric signals emitted by the second photoelectric sensor 85 correspond to the positions directly below the first electric clamping claw 12, the second electric clamping claw 33, the third electric clamping claw 47, the fourth electric clamping claw 54, and the fifth electric clamping claw 60, the accurate loading positions of each component can be ensured during assembly, thereby further improving assembly accuracy and increasing the product qualification rate.

[0028] It also includes an arc-extinguishing chamber clamping device 87, which includes an eighth fixed frame 88 fixedly connected to the equipment base 1, a fourteenth sliding base 89 slidably connected to the eighth fixed frame 88, a plurality of push rods 90 connected to the fourteenth sliding base 89, a fifteenth hydraulic cylinder 91 for driving the fourteenth sliding base 89 to move vertically, and a third photoelectric sensor 92 connected to the equipment base 1. The position of the third photoelectric sensor 92 corresponds to the position directly below the fourteenth sliding base 89. When the circuit breaker is located directly below the fourteenth sliding base 89, the position of the push rods 90 corresponds to the position of the arc-extinguishing chamber in the circuit breaker.

[0029] When the assembled circuit breaker moves to directly below the top rod 90 via the first conveyor belt 7, the controller 6 controls the fifteenth hydraulic cylinder 91 to drive the fourteenth sliding base 89 to move vertically downward, thereby causing the top rod 90 to press down and apply pressure to the paper arc breaker and epoxy arc breaker, further ensuring that the two types of arc breaker can be assembled in place, thereby further improving the product qualification rate.
