Description

Technical Field

[0001] This utility model relates to the field of circuit breaker processing equipment technology, and in particular to a high-efficiency assembly device for circuit breakers. Background Technology

[0002] A circuit breaker is a protective switch for branch circuits, housing contacts, arc-extinguishing chambers, trip units, and operating mechanisms within a plastic casing. The common assembly method in existing technology involves manually applying lubricating oil to the shaft support of the circuit breaker housing using brushes and scrapers. Then, the stationary contacts and magnetic yoke are installed into their designated positions. However, this method has the following problems: First, manual application of lubricating oil makes it difficult to accurately control the amount applied. Insufficient oil can cause the product to jam, while excessive oil can affect conduction in other positions, compromising product safety. Second, in existing technology, the stationary contacts and magnetic yoke are typically installed manually, and screwdrivers and clamps are used to force the parts into their designated positions. This process can result in incomplete installation and makes detection impossible. Therefore, a new type of circuit breaker assembly device is needed. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a highly efficient assembly device for circuit breakers that features a high degree of automation and high assembly accuracy.

The automatic lubrication device includes a first CCD vision inspection instrument connected to the equipment base, a first connecting base connected to the equipment base, and a slidably connected... The first connecting base includes a first sliding base, an injection element fixedly connected to the first sliding base, a pressurizing pump connected to the injection element, an oil reservoir connected to the pressurizing pump, and a first hydraulic cylinder for driving the first sliding base to move vertically. The detection direction of the first CCD vision inspection instrument is aligned directly below the injection element, which is located directly above the first conveyor belt. The clamping device includes a first fixed frame connected to the equipment base, a second fixed frame connected to the equipment base, a third fixed frame connected to the equipment base, a fourth fixed frame connected to the equipment base, a second sliding base slidably connected to the first fixed frame, a third sliding base slidably connected to the second sliding base, a first electric clamping jaw connected to the third sliding base, and a first hydraulic cylinder slidably connected to the first fixed frame. The second fixed frame includes a fourth sliding base, a fifth sliding base slidably connected to the fourth sliding base, a sixth sliding base slidably connected to the third fixed frame, a seventh sliding base slidably connected to the sixth sliding base, an eighth sliding base slidably connected to the fourth fixed frame, a ninth sliding base slidably connected to the eighth sliding base, a second electric clamping jaw connected to the fifth sliding base, a third electric clamping jaw connected to the seventh sliding base, a fourth electric clamping jaw connected to the ninth sliding base, a second hydraulic cylinder for driving the second sliding base to move horizontally, a third hydraulic cylinder for driving the third sliding base to move vertically, a fourth hydraulic cylinder for driving the fourth sliding base to move horizontally, and a fourth hydraulic cylinder for driving the fifth sliding base to move vertically. The system includes a fifth hydraulic cylinder for directional movement, a sixth hydraulic cylinder for driving the sixth sliding base to move horizontally, a seventh hydraulic cylinder for driving the seventh sliding base to move vertically, an eighth hydraulic cylinder for driving the eighth sliding base to move horizontally, and a ninth hydraulic cylinder for driving the ninth sliding base to move vertically. The movement directions of the second, third, fourth, and fifth sliding bases are all perpendicular to the movement direction of the first conveyor belt. The movement path of the first electric clamping claw passes directly above the first and second conveyor belts, and the movement path of the fourth electric clamping claw passes directly above the second conveyor belt and the discharge conveyor belt. When the second and third electric clamping claws are in their initial positions...The stationary contact feeding device and the magnetic yoke feeding device can respectively feed the stationary contact element and the magnetic yoke element to the corresponding positions of the second electric clamping jaw and the third electric clamping jaw. The controller is electrically connected to the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, the fourth hydraulic cylinder, the fifth hydraulic cylinder, the sixth hydraulic cylinder, the seventh hydraulic cylinder, the eighth hydraulic cylinder, the ninth hydraulic cylinder, the first drive motor, the second drive motor, the third drive motor, the first electric clamping jaw, the second electric clamping jaw, the third electric clamping jaw, the fourth electric clamping jaw, the pressure pump, and the first CCD vision inspection instrument.

[0005] Using the above technical solution, firstly, the circuit breaker housing to be processed is placed on the first conveyor belt. The first drive motor drives the first conveyor belt to move, moving the circuit breaker housing directly below the first CCD vision inspection instrument. The real-time image information captured by the first CCD vision inspection instrument is compared with the circuit breaker housing in its standard state. If the two match, the first drive motor stops working. Then, the controller controls the first hydraulic cylinder to drive the first sliding base to move vertically downward. Simultaneously, the pressure pump forces the lubricating oil in the oil tank into the oil injection element and then into the rotating shaft support position in the circuit breaker housing. After the oiling is completed, the controller controls the first sliding base to reset. Finally, the first CCD vision inspection instrument inspects the oiled circuit breaker housing. After the circuit breaker housing undergoes a secondary inspection and matches the standard oiled condition, the first CCD vision inspection device sends an electrical signal to the controller. The controller then controls the first drive motor to continue operating. When the circuit breaker housing moves directly below the first electric clamping claw, the controller controls the third hydraulic cylinder to move the third sliding base vertically downwards. The first electric clamping claw then clamps the circuit breaker housing. The second hydraulic cylinder then moves the second sliding base horizontally a certain distance, positioning the first electric clamping claw directly above the second conveyor belt. The circuit breaker housing is then placed on the second conveyor belt, and the second drive motor drives the second conveyor belt to move the circuit breaker housing to the outlet of the stationary contact loading device. The controller then controls the fourth hydraulic cylinder to move the fourth sliding base horizontally a certain distance, aligning the second electric clamping claw with the discharge port of the stationary contact feeding device. The controller then controls the fifth hydraulic cylinder to move the fifth sliding base vertically downwards, clamping the stationary contact element with the second electric clamping claw. The fourth and fifth hydraulic cylinders then move the fourth and fifth sliding bases respectively, aligning the clamped stationary contact with the corresponding installation position on the circuit breaker housing. The second drive motor then drives the second conveyor belt to continue moving. The third electric clamping claw then clamps the magnetic yoke element fed from the magnetic yoke feeding device. Finally, the sixth and seventh hydraulic cylinders move the sixth and seventh sliding bases respectively. The sliding base moves, and in conjunction with the third electric clamping claw, places the magnetic yoke element on the circuit breaker housing, completing the circuit breaker assembly. Then, the circuit breaker is transported by the second conveyor belt to directly below the fourth electric clamping claw. The ninth hydraulic cylinder then moves the ninth sliding base vertically downward, and the fourth electric clamping claw clamps the circuit breaker. The eighth and ninth hydraulic cylinders then move the eighth and ninth sliding bases respectively, causing the fourth electric clamping claw to move directly above the discharge conveyor belt and place it on the discharge conveyor belt. Finally, the controller controls the third drive motor to drive the processed circuit breaker to complete the discharge process. Compared with the traditional assembly method, this greatly improves assembly efficiency and accuracy.

[0006] Further features of this invention: The stationary contact head feeding device includes a feeding bin connected to the equipment base, a third conveyor belt connected to the equipment base, a limiting baffle hinged to the feeding bin, a connecting rod connected to the limiting baffle, a first rotary motor for driving the connecting rod, a feeding tray connected to the equipment base, a second CCD vision inspection instrument connected to the equipment base, a vibration motor connected to the bottom of the feeding tray, a robotic arm connected to the equipment base, a fourth connecting base connected to the robotic arm, a fifth electric clamping claw connected to the fourth connecting base, a first flat vibrating track connected to the equipment base, a fourth drive motor for driving the robotic arm, a fifth drive motor for driving the third conveyor belt, and a fifth drive motor for driving the third conveyor belt. The system includes a tenth hydraulic cylinder that drives the fifth electric gripper to move vertically, and a fourth rotary motor that drives the fourth connecting base to rotate. The limiting baffle is connected to the discharge port of the loading hopper. When the limiting baffle is in its initial position, the bottom of the limiting baffle is in contact with the upper surface of the third conveyor belt. The second CCD vision inspection instrument is located directly above the placement tray. When the robotic arm rotates a certain angle, the fifth electric gripper is located directly above the second conveyor belt. The robotic arm has two or more degrees of freedom. The controller is electrically connected to the first rotary motor, the vibration motor, the second CCD vision inspection instrument, the fifth electric gripper, the fourth drive motor, the fifth drive motor, and the tenth hydraulic cylinder.

[0007] Using the above technical solution, when stationary contacts need to be fed, firstly, the stationary contacts to be processed are placed in the feeding hopper. The fourth drive motor drives the third conveyor belt to move, causing the stationary contacts to move towards the discharge port. Then, the controller controls the first rotary motor to drive the connecting rod to rotate by a certain angle, thereby causing the limit baffle to rotate by a certain angle, allowing the stationary contacts to pass through the discharge port. Several stationary contacts fall onto the feeding tray. Then, the second CCD vision inspection instrument detects the stationary contacts placed on the feeding tray. If the orientation of the stationary contacts is incorrect, the controller controls the vibration motor to generate vibration force, causing the stationary contacts to bounce. The orientation of the stationary contacts may change. If the orientation of the stationary contacts is correct, the second CCD vision inspection instrument sends an electrical signal to the controller, and the controller... The robotic arm is controlled to move directly above the corresponding position, while the fourth rotary motor drives the fourth connecting base to rotate at a certain angle, so that the position of the fifth electric clamping claw matches the position of the stationary contact. Then, the tenth hydraulic cylinder drives the fifth electric clamping claw to move vertically downward to complete the clamping work. The controller then controls the robotic arm to move to the first vibration track and places it on the first vibration track. The first vibration track then vibrates to the end, and the second electric clamping claw clamps it onto the circuit breaker housing, completing the assembly of the stationary contact. The purpose of this assembly method is to automatically select the stationary contact with the correct orientation, greatly improving the automation level of the equipment. At the same time, this method of loading the stationary contact can reduce the friction during the loading process and reduce product wear.

[0008] Further features of this invention: The magnetic yoke feeding device includes a rotary vibrating feed disc, a second flat vibrating track connected to the rotary vibrating feed disc, a second connecting base movably connected to the equipment base, an eleventh hydraulic cylinder connected to the second connecting base, a sixth electric clamping claw connected to the eleventh hydraulic cylinder, and a second rotary motor for driving the second connecting base to rotate. When the second connecting base rotates a certain angle, the position of the sixth electric clamping claw corresponds to that of the third electric clamping claw. When the second connecting base is in the initial position, the position of the sixth electric clamping claw corresponds to the end of the second flat vibrating track. The controller is electrically connected to the eleventh hydraulic cylinder, the sixth electric clamping claw, and the second rotary motor respectively.

[0009] Using the above technical solution, when the magnetic yoke element needs to be fed, the magnetic yoke element is first transferred to the second horizontal vibration track by a rotating vibrating feed plate. Then, the magnetic yoke element is vibrated to the end of the second horizontal vibration track. Next, the second rotating motor drives the second connecting base to rotate a certain angle, so that the position of the sixth electric clamping claw corresponds to the end of the second horizontal vibration track. Then, the eleventh hydraulic cylinder drives the sixth electric clamping claw to move a certain distance in the horizontal direction. After the sixth electric clamping claw completes the clamping work, the second rotating motor drives the second connecting base to rotate 90 degrees, so that the position of the sixth electric clamping claw corresponds to the position of the third electric clamping claw. The magnetic yoke element is transferred from the sixth electric clamping claw to the third electric clamping claw, and finally the assembly of the magnetic yoke element is completed. This feeding method can further improve the automation level and working efficiency of this device.

[0010] A further feature of this invention includes a barcode labeling device, comprising a barcode printer connected to the equipment base, a host computer electrically connected to the barcode printer, a third connecting base connected to the equipment base, a twelfth hydraulic cylinder connected to the third connecting base, a vacuum adsorption assembly connected to the twelfth hydraulic cylinder, and a third rotary motor for driving the third connecting base to rotate. When the third connecting base rotates at a certain angle, the position of the vacuum adsorption assembly is aligned with the position of the first conveyor belt. The controller is electrically connected to the host computer, the barcode printer, the twelfth hydraulic cylinder, the vacuum adsorption assembly, and the third rotary motor.

[0011] Using the above technical solution, when the circuit breaker moves to the corresponding position of the barcode labeling device, the host computer sends an electrical signal to the barcode printer. The host computer retrieves the corresponding product parameters and automatically generates a barcode. After the barcode printer prints the corresponding barcode, the barcode is held by the vacuum adsorption component. The third rotary motor drives the third connecting base to rotate 180 degrees, and the twelfth hydraulic cylinder drives the vacuum adsorption component to move a certain distance in the horizontal direction, so that the barcode is affixed to the circuit breaker housing. In this way, the production status of the product can be traced through the barcode, ensuring that the product can be traced throughout the circulation process. Once a defective product is found, it can be immediately identified at which stage the problem occurred, facilitating subsequent product maintenance. Attached Figure Description

[0020] First, the circuit breaker housing to be processed is placed on the first conveyor belt 2. The first drive motor 4 drives the first conveyor belt 2 to move, moving the circuit breaker housing directly below the first CCD vision inspection instrument 13. The real-time image information captured by the first CCD vision inspection instrument 13 is compared with the circuit breaker housing in its standard state. If the two match, the first drive motor 4 stops working. Then, the controller 12 controls the first hydraulic cylinder 19 to drive the first sliding base 15 to move vertically downward. At the same time, the pressure pump 17 pressurizes the lubricating oil in the oil tank 18 into the oil injection element 16 and then flows into the rotating shaft support position in the circuit breaker housing. After the oiling is completed, the controller 12 controls the first sliding base 15 to reset, and then the first... The CCD vision inspection unit 13 performs a secondary inspection on the lubricated circuit breaker housing. Once it matches the standard lubricated condition, the first CCD vision inspection unit 13 sends an electrical signal to the controller 12. The controller 12 then controls the first drive motor 4 to continue operating. When the circuit breaker housing moves directly below the first electric clamping claw 26, the controller 12 controls the third hydraulic cylinder 37 to move the third sliding base 25 vertically downwards. The first electric clamping claw 26 then clamps the circuit breaker housing. The second hydraulic cylinder 36 then moves the second sliding base 24 horizontally a certain distance, positioning the first electric clamping claw 26 directly above the second conveyor belt 3. The circuit breaker housing is then placed on the second conveyor belt 3 and then... The second drive motor 5 drives the second conveyor belt 3 to move.

Then, the controller 12 controls the fourth hydraulic cylinder 38 to move the fourth sliding base 27 horizontally a certain distance, so that the position of the second electric clamping claw 33 is aligned with the discharge port of the stationary contact feeding device 8. The controller 12 controls the fifth hydraulic cylinder 39 to move the fifth sliding base 28 vertically downward, and the second electric clamping claw 33 clamps the stationary contact element. Then, the fourth hydraulic cylinder 38 and the fifth hydraulic cylinder 39 respectively drive the fourth sliding base 27 and the fifth sliding base 28 to move, so that the clamped stationary contact is aligned with the corresponding installation position of the circuit breaker housing. Then, the second drive motor... 5 drives the second conveyor belt 3 to continue moving, and then the third electric clamping jaw 34 clamps the magnetic yoke element fed from the magnetic yoke feeding device 9. Then, the sixth hydraulic cylinder 40 and the seventh hydraulic cylinder 41 drive the sixth sliding base 29 and the seventh sliding base 30 to move respectively. With the help of the third electric clamping jaw 34, the magnetic yoke element is placed on the circuit breaker housing, completing the circuit breaker assembly.

[0022] When stationary contacts need to be fed, firstly, the stationary contacts to be processed are placed in the feeding hopper 44. The fourth drive motor 56 drives the third conveyor belt 45 to move, thereby causing the stationary contacts to move towards the discharge port. Then, the controller 12 controls the first rotary motor 48 to drive the connecting rod 47 to rotate a certain angle, thereby causing the limit baffle 46 to rotate a certain angle, so that the stationary contacts pass through the discharge port and several stationary contacts fall onto the discharge tray 49. Then, the second CCD vision inspection instrument 50 inspects the stationary contacts placed on the discharge tray 49. If the orientation of the stationary contacts is incorrect, the controller 12 controls the vibration motor 51 to generate vibration force, causing the stationary contacts to bounce, and the orientation of the stationary contacts may change. If the orientation of the stationary contacts is correct, the second CCD vision inspection instrument 50 sends an electrical signal to the controller 12, and the controller 12 controls... The robotic arm 52 moves to directly above the corresponding position, and simultaneously controls the fourth rotary motor 59 to drive the fourth connecting base 53 to rotate a certain angle, so that the position of the fifth electric clamping claw 54 matches the position of the stationary contact. Then, the tenth hydraulic cylinder 58 drives the fifth electric clamping claw 54 to move vertically downward to complete the clamping work. Then, the controller 12 controls the robotic arm 52 to move to the first vibration track 55 and place it on the first vibration track 55. Then, the first vibration track 55 vibrates to the end, and the second electric clamping claw 33 clamps it onto the circuit breaker housing, completing the assembly of the stationary contact.

When the second connecting base 62 is in the initial position, the position of the sixth electric clamping claw 64 corresponds to the end of the second flat vibrating track 61. The controller 12 is electrically connected to the eleventh hydraulic cylinder 63, the sixth electric clamping claw 64, and the second rotary motor 65, respectively.

[0024] When the magnetic yoke element needs to be fed, the magnetic yoke element is first transferred to the second vibrating track 61 by the rotating vibrating feed plate 60. Then, the magnetic yoke element is vibrated to the end of the second vibrating track 61 by the second vibrating track 61. Then, the second connecting base 62 is rotated by the second rotary motor 65 at a certain angle so that the position of the sixth electric clamping claw 64 corresponds to the end of the second vibrating track 61. Then, the sixth electric clamping claw 64 is moved horizontally a certain distance by the eleventh hydraulic cylinder 63. After the sixth electric clamping claw 64 completes the clamping work, the second rotary motor 65 drives the second connecting base 62 to rotate 90 degrees so that the position of the sixth electric clamping claw 64 corresponds to the position of the third electric clamping claw 34. The magnetic yoke element is transferred from the sixth electric clamping claw 64 to the third electric clamping claw 34, and the assembly of the magnetic yoke element is finally completed.

The controller 12 is electrically connected to the host computer 68, the barcode printer 67, the twelfth hydraulic cylinder 70, the vacuum adsorption component 71, and the third rotary motor 72.

[0026] When the circuit breaker moves to the corresponding position of the barcode labeling device 66, the host computer 68 sends an electrical signal to the barcode printer 67. The host computer 68 retrieves the corresponding product parameters and automatically generates a barcode. After the barcode printer 67 prints the corresponding barcode, the barcode is picked up by the vacuum adsorption component 71. The third rotary motor 72 drives the third connecting base 69 to rotate 180 degrees, and the twelfth hydraulic cylinder 70 drives the vacuum adsorption component 71 to move a certain distance in the horizontal direction, so that the barcode is affixed to the circuit breaker housing. In this way, the production status of the product can be traced through the barcode, ensuring that the product can be traced in the circulation process. Once a defective product is found, it can be immediately known at which stage the problem occurred, which facilitates subsequent product maintenance.
