[0005] According to the technical solution, first, the circuit breaker to be processed is fed through the transmission line. When the circuit breaker to be processed is transmitted to the position of the blocking plate, the circuit breaker cannot move forward. Then, the first hydraulic cylinder is controlled by the controller to push the first pushing plate to move in the direction of the first placing plate, so that the circuit breaker enters the first placing plate. At the same time, the protective cover to be processed is first fed to the flat vibration track by rotating the feed disk.

Then, the first clamping device is controlled by the controller to clamp the circuit breaker from the first placing plate to the installation station. The protective cover is clamped by the second clamping device. It is clamped from the end of the flat vibration rail and placed on the installation position of the circuit breaker, and then the third hydraulic cylinder is controlled by the controller to drive the installation station to move in the horizontal direction. When the installation station moves to the bottom of the punch head, the third hydraulic cylinder stops working, and then the second hydraulic cylinder is controlled by the controller to drive the punch head to press down, so that the shield is installed on the circuit breaker. When the assembly work is completed, the installation station continues to move in the direction of the third clamping device, and the assembled circuit breaker is clamped from the installation station to the transmission line by the third clamping device, and then the circuit breaker is driven to continue to move through the transmission line, so that the assembled circuit breaker is discharged.

[0007] The utility model is further configured as follows: the second clamping device includes a buffer base slidably connected to the equipment base, a sixth hydraulic cylinder for driving the buffer base to move, a second fixed base connected to the equipment base, a third sliding base slidably connected to the second fixed base, a fourth sliding base slidably connected to the third sliding base, a second electric clamping claw connected to the fourth sliding base, a seventh hydraulic cylinder for driving the third sliding base to move in a horizontal direction, an eighth hydraulic cylinder for driving the fourth sliding base to move in a vertical direction, a third fixed base fixedly connected to the equipment base, a fifth sliding base slidably connected to the third fixed base, a sixth sliding base slidably connected to the fifth sliding base, a third electric clamping claw connected to the sixth sliding base, and a method for driving the fifth sliding base A ninth hydraulic cylinder that moves in the horizontal direction and a tenth hydraulic cylinder that drives the sixth sliding base to move in the vertical direction, the buffer base is provided with a plurality of fixed grooves for placing the shield, and the fixed grooves are adapted to the shape and size of the shield to be processed. When the buffer base is in the initial state, the buffer base is located directly below the second electric clamping claw, the movement direction of the third sliding base is from the end of the flat vibration track to the buffer base, the movement direction of the fifth sliding base is from the buffer base to the installation station, the movement direction of the fifth sliding base is parallel to the movement direction of the buffer base, and the controller is electrically connected to the sixth hydraulic cylinder, the seventh hydraulic cylinder, the eighth hydraulic cylinder, the ninth hydraulic cylinder, the tenth hydraulic cylinder, the second electric clamping claw and the third electric clamping claw respectively.

[0008] By adopting the above technical solution, first, the sixth hydraulic cylinder is controlled by the controller to drive the buffer base to move to a position corresponding to the end of the flat vibration track, and then the seventh hydraulic cylinder is controlled by the controller to drive the third sliding base to move horizontally to above the flat vibration track, and then the eighth hydraulic cylinder is controlled by the controller to drive the fourth sliding base to move vertically, so that the second electric clamping claw moves to the corresponding position of the shield and clamps the shield, and then the seventh hydraulic cylinder and the eighth hydraulic cylinder are controlled by the controller to drive the third sliding base and the fourth sliding base to move to above the buffer base and place the shield to be processed. On the buffer base, the sixth hydraulic cylinder is controlled to drive the buffer base to move a certain distance in the direction of the third electric clamping claw, and then the ninth hydraulic cylinder and the tenth hydraulic cylinder are controlled by the controller to respectively drive the fifth sliding base and the sixth sliding base to move, so that the third electric clamping claw moves to the top of the buffer base and clamps the guard on the buffer base to the installation position of the circuit breaker on the installation station.

With the above technical solution, when the circuit breaker moves to the position of the blocking plate through the transmission line, the controller controls the flip cylinder to drive the first material loading plate to rotate 90 degrees, and then the first hydraulic cylinder drives the first push plate to push the circuit breaker onto the first material loading plate. Since the first material loading plate is L-shaped, when the circuit breaker to be processed moves into place, one end of the first material loading plate will block the circuit breaker, making it unable to move forward, and then the controller controls the flip cylinder to drive the first material loading plate to rotate 90 degrees in the opposite direction, which can further ensure the accurate feeding position of the circuit breaker, thereby avoiding the first electric clamping claw from clamping empty space.

[0010] The utility model is further configured as follows: the third clamping device includes a fourth fixed frame connected to the equipment base, a seventh sliding base slidably connected to the fourth fixed frame, an eighth sliding base slidably connected to the seventh sliding base, a fourth electric clamping claw connected to the eighth sliding base, an eleventh hydraulic cylinder for driving the seventh sliding base to move in a horizontal direction, and a twelfth hydraulic cylinder for driving the eighth sliding base to move in a vertical direction.

The controller is electrically connected to the eleventh hydraulic cylinder, the twelfth hydraulic cylinder and the fourth electric clamping claw, respectively.

[0011] By adopting the above technical scheme, when the circuit breaker is assembled, the installation station is driven by the second hydraulic cylinder to move to the corresponding position of the fourth electric clamping claw, and then the twelfth hydraulic cylinder is controlled by the controller to drive the eighth sliding base to move vertically downward, and then the assembled circuit breaker is clamped by the fourth electric clamping claw, and then the twelfth hydraulic cylinder is controlled by the controller to drive the eighth sliding base to reset, and the eleventh hydraulic cylinder is controlled by the controller to drive the seventh sliding base to move to just above the transmission line, and then the twelfth hydraulic cylinder is used to drive the eighth sliding base to move vertically downward, and the fourth electric clamping claw releases the assembled circuit breaker, and the circuit breaker is discharged through the transmission line.

[0012] The utility model is further configured as follows: the assembly frame is provided with a push rod slidably connected to the assembly frame, a limit plate fixedly connected to the assembly frame, and a thirteenth hydraulic cylinder for driving the push rod to move in the horizontal direction. The movement direction of the push rod is perpendicular to the movement direction of the installation station. When the installation station is located directly below the punch head, the push rod corresponds to the position of the limit plate and the circuit breaker on the installation station, respectively. The controller is electrically connected to the thirteenth hydraulic cylinder. With the above technical solution, when the installation station moves to below the punch head, the controller controls the third hydraulic cylinder to stop working, and then controls the thirteenth hydraulic cylinder through the controller to drive the push rod to move in the direction of the circuit breaker, so that the circuit breaker and the shield to be assembled are clamped between the push rod and the limit plate, avoiding the circuit breaker and the shield from relative sliding in the horizontal direction. Then, the controller controls the second hydraulic cylinder to drive the punch head downward, which can further ensure that the shield can be installed in place on the circuit breaker.

[0013] The utility model is further configured as follows: the assembly frame is provided with a photoelectric sensor connected to the assembly frame, a positioning baffle slidably connected to the assembly frame and a fourteenth hydraulic cylinder for driving the positioning baffle to move in a horizontal direction; a limiting groove is provided on the positioning baffle; the width of the limiting groove is adapted to the width of the circuit breaker to be assembled; the movement direction of the positioning baffle is perpendicular to the movement direction of the installation station; the installation station first passes through the position of the positioning baffle and then passes under the punch head; the photoelectric sensor corresponds to the position of the positioning baffle; the controller is electrically connected to the photoelectric sensor and the fourteenth hydraulic cylinder.

[0014] By adopting the above technical solution, when the installation station moves to the position corresponding to the positioning baffle, the photoelectric sensor senses that the installation station is in place, and the photoelectric sensor sends an electrical signal to the controller. The controller controls the third hydraulic cylinder to stop working. At the same time, the controller controls the fourteenth hydraulic cylinder to drive the positioning baffle to move toward the installation station. Since the width of the limiting groove is adapted to the width of the circuit breaker to be assembled, the positioning baffle will adjust the relative position of the protective cover and the circuit breaker to ensure that the edge positions of the protective cover and the circuit breaker are aligned. Then the controller controls the third hydraulic cylinder to drive the installation station to continue moving, so that the circuit breaker is assembled. This can further improve the accuracy of the assembly and avoid defective products. BRIEF DESCRIPTION OF THE DRAWINGS

The controller 8 is electrically connected to the first hydraulic cylinder 13, the second hydraulic cylinder 21, the third hydraulic cylinder 22, the flat vibration device 17, the first clamping device 5, the second clamping device 6 and the third clamping device 7 respectively.

[0022] First, the circuit breaker to be processed is fed through the transmission line 9. When the circuit breaker to be processed is transmitted to the position of the blocking plate 10, the circuit breaker cannot move forward. Then, the controller 8 controls the first hydraulic cylinder 13 to push the first pushing plate 12 to move toward the first placing plate 14, so that the circuit breaker enters the first placing plate 14. At the same time, the protective cover to be processed is first fed to the flat vibration track 16 by rotating the feed disk 15. Then, the controller 8 controls the flat vibration device 17 to work, so that the protective cover moves to the end of the flat vibration track 16.

The end of the rail 16 is clamped and placed on the installation position of the circuit breaker, and then the third hydraulic cylinder 22 is controlled by the controller 8 to drive the installation station 19 to move in the horizontal direction. When the installation station 19 moves to the bottom of the punch head 20, the third hydraulic cylinder 22 stops working, and then the second hydraulic cylinder 21 is controlled by the controller 8 to drive the punch head 20 to press down, so that the shield is installed on the circuit breaker. When the assembly work is completed, the installation station 19 continues to move in the direction of the third clamping device 7, and the assembled circuit breaker is clamped from the installation station 19 to the transmission line 9 by the third clamping device 7, and then the circuit breaker is driven to continue to move through the transmission line 9, so that the assembled circuit breaker is discharged. The first clamping device 5 includes a first fixed base 23 connected to the equipment base 1, a first sliding base 24 slidably connected to the first fixed base 23, a second sliding base 25 slidably connected to the first sliding base 24, a first electric clamping claw 26 connected to the second sliding base 25, a fourth hydraulic cylinder 27 for driving the first sliding base 24 to move in a horizontal direction, and a fifth hydraulic cylinder 28 for driving the second sliding base 25 to move in a vertical direction. The controller 8 is electrically connected to the first electric clamping claw 26, the fourth hydraulic cylinder 27 and the fifth hydraulic cylinder 28, respectively.

[0023] When it is necessary to clamp the circuit breaker from the first loading plate 14 to the installation station 19, first, the fourth hydraulic cylinder 27 is controlled by the controller 8 to drive the first sliding base 24 to move in the horizontal direction, so that the first electric clamping claw 26 moves to the top of the first loading plate 14, and then the fifth hydraulic cylinder 28 is controlled by the controller 8 to drive the second sliding base 25 to move in the vertical direction, so that the first electric clamping claw 26 corresponds to the position of the circuit breaker to be processed, and then the first electric clamping claw 26 is controlled by the controller 8 to clamp the circuit breaker to be processed, and then the first sliding base 24 and the second sliding base 25 are driven to move by the fourth hydraulic cylinder 27 and the fifth hydraulic cylinder 28 respectively, so that the first electric clamping claw 26 moves to the installation station 19, so that the movement stroke of the first sliding base 24 and the second sliding base 25 are the same each time, which can ensure that the first electric clamping claw 26 can stably clamp the circuit breaker to be processed, and ensure that the circuit breaker to be processed can be stably fed to avoid assembly errors.

[0024] The second clamping device 6 includes a buffer base 29 slidably connected to the equipment base 1, a sixth hydraulic cylinder 30 for driving the buffer base 29 to move, a second fixed base 31 connected to the equipment base 1, a third sliding base 32 slidably connected to the second fixed base 31, a fourth sliding base 33 slidably connected to the third sliding base 32, a second electric clamping claw 34 connected to the fourth sliding base 33, a seventh hydraulic cylinder 35 for driving the third sliding base 32 to move in a horizontal direction, an eighth hydraulic cylinder 36 for driving the fourth sliding base 33 to move in a vertical direction, a third fixed base 37 fixedly connected to the equipment base 1, a fifth sliding base 38 slidably connected to the third fixed base 37, a sixth sliding base 39 slidably connected to the fifth sliding base 38, a third electric clamping claw 40 connected to the sixth sliding base 39, and a third electric clamping claw 41 for driving the fifth sliding base 38 to move in a horizontal direction. The ninth hydraulic cylinder 41 and the tenth hydraulic cylinder 42 for driving the sixth sliding base 39 to move in the vertical direction, the buffer base 29 is provided with a plurality of fixed grooves 43 for placing the shield, and the fixed grooves 43 are adapted to the shape and size of the shield to be processed. When the buffer base 29 is in the initial state, the buffer base 29 is located directly below the second electric clamping claw 34, and the movement direction of the third sliding base 32 is from the end of the flat vibration track 16 to the buffer base 29, and the movement direction of the fifth sliding base 38 is from the buffer base 29 to the installation station 19. The movement direction of the fifth sliding base 38 is parallel to the movement direction of the buffer base 29, and the controller 8 is electrically connected to the sixth hydraulic cylinder 30, the seventh hydraulic cylinder 35, the eighth hydraulic cylinder 36, the ninth hydraulic cylinder 41, the tenth hydraulic cylinder 42, the second electric clamping claw 34 and the third electric clamping claw 40 respectively.

[0025] First, the controller 8 controls the sixth hydraulic cylinder 30 to drive the buffer base 29 to move to a position corresponding to the end of the flat vibration track 16, and then controls the seventh hydraulic cylinder 35 to drive the third sliding base 32 to move horizontally to above the flat vibration track 16, and then controls the eighth hydraulic cylinder 36 to drive the fourth sliding base 33 to move vertically, so that the second electric clamping claw 34 moves to the corresponding position of the shield and clamps the shield, and then controls the seventh hydraulic cylinder 35 and the eighth hydraulic cylinder 36 to respectively drive the third sliding base 32 and the fourth sliding base 33 to move above the buffer base 29 and place the shield to be processed on the buffer base 29. The buffer base 29 is then driven by the sixth hydraulic cylinder 30 to move a certain distance in the direction of the third electric clamping claw 40, and then the ninth hydraulic cylinder 41 and the tenth hydraulic cylinder 42 are controlled by the controller 8 to respectively drive the fifth sliding base 38 and the sixth sliding base 39 to move, so that the third electric clamping claw 40 moves to the top of the buffer base 29 and clamps the shield on the buffer base 29 to the installation position of the circuit breaker on the installation station 19. This clamping method can ensure that the movement distance of each sliding base is always kept fixed, thereby ensuring that the shield can be accurately clamped to the installation station 19, thereby improving the assembly accuracy of the device.

[0026] The first material loading plate 14 is L-shaped and is hinged to the equipment base 1 . A flip cylinder 44 is provided at one end of the first material loading plate 14 . The flip cylinder 44 can rotate the first material loading plate 14 90 degrees. The controller 8 is electrically connected to the flip cylinder 44 .

[0027] When the circuit breaker moves to the position of the blocking plate 10 through the transmission line 9, the controller 8 controls the flip cylinder 44 to drive the first material loading plate 14 to rotate 90 degrees, and then the first hydraulic cylinder 13 drives the first pushing plate 12 to push the circuit breaker onto the first material loading plate 14. Since the first material loading plate 14 is L-shaped, when the circuit breaker to be processed moves into place, one end of the first material loading plate 14 will block the circuit breaker, making it impossible for the circuit breaker to move forward. Then, the controller 8 controls the flip cylinder 44 to drive the first material loading plate 14 to rotate 90 degrees in the opposite direction, which can further ensure the accurate feeding position of the circuit breaker, thereby avoiding the first electric clamping claw 26 from being clamped empty.

[0028] The third clamping device 7 includes a fourth fixed frame 45 connected to the equipment base 1, a seventh sliding base 46 slidably connected to the fourth fixed frame 45, an eighth sliding base 47 slidably connected to the seventh sliding base 46, a fourth electric clamping claw 48 connected to the eighth sliding base 47, an eleventh hydraulic cylinder 49 for driving the seventh sliding base 46 to move in a horizontal direction, and a twelfth hydraulic cylinder 50 for driving the eighth sliding base 47 to move in a vertical direction. The movement direction of the seventh sliding base 46 is perpendicular to the movement direction of the transmission line 9. The fourth electric clamping claw 48 can clamp the assembled circuit breaker from the installation station 19 to the transmission line 9. The controller 8 is electrically connected to the eleventh hydraulic cylinder 49, the twelfth hydraulic cylinder 50 and the fourth electric clamping claw 48, respectively.

[0029] When the circuit breaker is assembled, the installation station 19 is driven by the second hydraulic cylinder 21 to move to the corresponding position of the fourth electric clamping claw 48, and then the twelfth hydraulic cylinder 50 is controlled by the controller 8 to drive the eighth sliding base 47 to move vertically downward, and then the assembled circuit breaker is clamped by the fourth electric clamping claw 48, and then the twelfth hydraulic cylinder 50 is controlled by the controller 8 to drive the eighth sliding base 47 to reset, and the eleventh hydraulic cylinder 49 is controlled by the controller 8 to drive the seventh sliding base 46 to move to the top of the transmission line 9, and then the twelfth hydraulic cylinder 50 is used to drive the eighth sliding base 47 to move vertically downward, and the fourth electric clamping claw 48 releases the assembled circuit breaker, and the circuit breaker is discharged through the transmission line 9. The assembly frame 18 is provided with a push rod 51 slidably connected to the assembly frame 18, a limit plate 52 fixedly connected to the assembly frame 18 and a thirteenth hydraulic cylinder 53 for driving the push rod 51 to move in the horizontal direction. The movement direction of the push rod 51 is perpendicular to the movement direction of the installation station 19. When the installation station 19 is located directly below the punching head 20, the push rod 51 corresponds to the positions of the limit plate 52 and the circuit breaker on the installation station 19 respectively, and the controller 8 is electrically connected to the thirteenth hydraulic cylinder 53.

[0030] When the installation station 19 moves to the bottom of the punch head 20, the controller 8 controls the third hydraulic cylinder 22 to stop working, and then controls the thirteenth hydraulic cylinder 53 through the controller 8 to drive the push rod 51 to move in the direction of the circuit breaker, so that the circuit breaker and the protective cover to be assembled are clamped between the push rod 51 and the limit plate 52 to prevent the circuit breaker and the protective cover from sliding relative to each other in the horizontal direction, and then controls the second hydraulic cylinder 21 through the controller 8 to drive the punch head 20 to press down, which can further ensure that the protective cover can be installed in place on the circuit breaker.

[0031] The assembly frame 18 is provided with a photoelectric sensor 54 connected to the assembly frame 18, a positioning baffle 55 slidably connected to the assembly frame 18 and a fourteenth hydraulic cylinder 56 for driving the positioning baffle 55 to move in the horizontal direction. The positioning baffle 55 is provided with a limiting groove 57, and the width of the limiting groove 57 is adapted to the width of the circuit breaker to be assembled. The movement direction of the positioning baffle 55 is perpendicular to the movement direction of the installation station 19. The installation station 19 first passes through the position of the positioning baffle 55 and then passes under the punch head 20. The photoelectric sensor 54 corresponds to the position of the positioning baffle 55. The controller 8 is electrically connected to the photoelectric sensor 54 and the fourteenth hydraulic cylinder 56.

[0032] When the installation station 19 moves to the position corresponding to the positioning baffle 55, the photoelectric sensor 54 senses that the installation station 19 is in place, and the photoelectric sensor 54 sends an electrical signal to the controller 8. The controller 8 controls the third hydraulic cylinder 22 to stop working. At the same time, the controller 8 controls the fourteenth hydraulic cylinder 56 to drive the positioning baffle 55 to move toward the installation station 19. Since the width of the limiting groove 57 is compatible with the width of the circuit breaker to be assembled, the positioning baffle 55 will adjust the relative position of the shield and the circuit breaker to ensure that the edge positions of the shield and the circuit breaker are aligned. Then the controller 8 controls the third hydraulic cylinder 22 to drive the installation station 19 to continue moving, so that the circuit breaker is assembled. This can further improve the accuracy of assembly and avoid defective products.
