Technical Field

[0002] As an important electrical equipment, the circuit breaker is an electrical appliance that can automatically protect against loss of voltage, undervoltage, overload and short circuit under specified conditions. At the same time, it is also used to distribute electrical energy and automatically cut off the circuit when the circuit has faults such as overload, short circuit or undervoltage, thereby protecting the distribution circuit, motor or other electrical equipment from damage.
[0003] Nowadays, circuit breakers need to undergo quality inspections during the actual production process to determine whether they can work properly and whether they can open and close the circuit and conduct the circuit, so as to screen out defective products and prevent them from entering the market. In traditional inspection technology, it is necessary to manually insert the conductive parts into the wiring jacks of the circuit breaker to connect the circuit breaker to the circuit, and then push the handle on the top of the circuit breaker to close and open the circuit breaker to observe whether the circuit breaker can be used normally.
[0004] However, although this operation mode can realize the test of circuit breakers, the test mode of manual wiring, unplugging and then observing is inefficient.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0040] like Figure 1 As shown, an existing circuit breaker has wiring sockets at both ends and a handle at the top. When the handles are placed at the two ends, the circuit breaker is in a closed state and an open state respectively.
[0041] During the specific testing process of the circuit breaker, two conductive parts need to be inserted into the wiring jacks at both ends of the circuit breaker to connect the circuit breaker to the circuit, and then the handle on the top of the circuit breaker is pushed to detect whether the circuit breaker can open and close the circuit normally. However, the traditional detection method has a high degree of manual participation, which not only leads to low test efficiency, but also manual detection is prone to errors.
[0042] In order to solve the above problems, the present invention proposes the following technical solutions:
[0043] See also Figure 2 - Fig.10, A test device for power equipment production, including a test production line 100. The test production line 100 includes a frame 101 and a chain conveyor belt 102 arranged inside the frame 101. It also includes a receiving mechanism 200, a mounting frame 300, a test mechanism 400 and a power supply 500. Among them, the number of receiving mechanisms 200 is several, and several receiving mechanisms 200 are evenly spaced on the outer surface of the chain conveyor belt 102. The receiving mechanism 200 is used to place the circuit breakers to be tested; it is worth mentioning that during the actual test process, a clamping robot (not shown in the figure) can be arranged at the front end and the rear end of the test production line respectively. One clamping robot is used to continuously put the circuit breakers to be tested into the receiving mechanism 200, and the other clamping robot is used to take out the tested circuit breakers one by one.
[0044] Furthermore, the receiving mechanism 200 includes a T-shaped seat plate 201 and a receiving part 202. The T-shaped seat plate 201 is fixedly arranged on the outer surface of the chain conveyor belt 102, and the receiving part 202 is fixedly arranged on the surface of the T-shaped seat plate 201, and the receiving part 202 is a cuboid hollow structure without a cover on the top; the internal width and length of the receiving part 202 are equivalent to the bottom width and length of the circuit breaker to be tested. That is, after inserting the bottom of the circuit breaker into the inside of the receiving part 202, the stability of the circuit breaker can be exactly ensured, and the circuit breaker can be prevented from shaking back and forth.
[0045] In addition, the mounting frame 300 is in a "冂" shape, and the mounting frame 300 is slidably arranged on the top surface of the frame 101 along the conveying direction of the chain conveyor belt 102; specifically, a chute distributed along the length direction of the frame 101 is opened on the top surface of the frame 101, and the mounting frame 300 is slidably matched with the chute; the test mechanism 400 is arranged on the mounting frame 300. The test mechanism 400 includes two conductive insertion rods 401 and a current sensor 402 (model: MIK-DJI-C). The two conductive insertion rods 401 are symmetrically distributed on both sides of the mounting frame 300, and the conductive insertion rods 401 are slidably matched with the side walls of the mounting frame 300. The two conductive insertion rods 401 are respectively used to insert into the wiring jacks at both ends of the circuit breaker; it should be noted that when the circuit breaker to be tested is placed inside the receiving part 202, the height of the wiring jack of the circuit breaker is the same as that of the conductive insertion rod 401.
[0046] The power supply 500 is arranged on the inner side of the frame 101, and the two conductive rods 401 are respectively connected to the positive and negative poles of the power supply 500 through wires, and the current sensor 402 is arranged on the line connecting one of the conductive rods 401 and the power supply 500; therefore, when the inner ends of the two conductive rods 401 are respectively inserted into the wiring jacks at both ends of the circuit breaker, the circuit breaker is connected to the circuit. At this time, as long as the circuit breaker is closed, the current sensor 402 can detect the current value on the line; this embodiment also includes a controller (model BMEP581020), the signal output end of the current sensor 402 is connected to the controller, and the signal output end of the controller is connected to the power source of the chain plate conveyor belt 102 (that is, the motor used to drive the chain plate conveyor belt 102 to move). When the detection value of the current sensor 402 is inconsistent with the standard value, the controller controls the chain plate conveyor belt 102 to stop running, thereby reminding the staff that the circuit breaker being tested has a fault.
[0047] It should be noted that the circuit breaker is equivalent to a switch in the circuit. When the circuit breaker is disconnected, the detection value of the current sensor 402 is 0. When the circuit breaker is closed, the circuit breaker is equivalent to a conductor with very low resistance, so the detection value of the current sensor 402 is a standard value. Therefore, in the actual test process, as long as the detection value of the current sensor 402 is neither zero nor a standard value, the controller can determine that the circuit breaker is faulty. In addition, it should be added that a fixed value resistor is also provided on the line connecting the conductive plug 401 and the power supply 500 to prevent the circuit from short-circuiting.
[0048] In some embodiments of the present application, abutment rods 301 are symmetrically arranged on both side walls of the mounting frame 300, and the abutment rods 301 are slidably matched with the side walls of the mounting frame 300. The position height of the abutment rods 301 is equivalent to the height of the accommodating mechanism 200. When the accommodating mechanism 200 contacts the abutment rods 301, the two conductive plug rods 401 are respectively aligned with the wiring jacks of the circuit breaker to be tested. The abutment rods 301 movably penetrate the side walls of the mounting frame 300, so the abutment rods 301 can slide along their own axis.
[0049] Furthermore, wiring slots 103 are symmetrically provided on both sides of the top surface of the rack 101, and wiring posts 302 are provided at the outer ends of the abutment rods 301, and the wiring posts 302 are movably inserted into the wiring slots 103; the wiring slots 103 are a two-section structure consisting of a horizontal section 1031 and an inclined section 1032. When the wiring posts 302 are located inside the horizontal section 1031, the distance between the two abutment rods 301 is smaller than the length of the accommodating portion 202; when the wiring posts 302 are located inside the inclined section 1032 and away from the side of the horizontal section 1031, the distance between the two abutment rods 301 is greater than the length of the accommodating portion 202. Among them, the horizontal section 1031 is consistent with the length direction of the rack 101, so when the wiring post 302 is located inside the horizontal section 1031, the distance between the two abutment rods 301 remains unchanged; when the wiring post 302 is located inside the inclined section 1032 and moves toward the side away from the horizontal section 1031, the two abutment rods 301 move away from each other.
[0050] The test mechanism 400 is described in detail below:
[0051] The test mechanism 400 also includes two hard insulating sleeves 403, which are respectively wrapped around the outside of the two conductive plugs 401, and a protective tube 404 is also provided on the outside of the hard insulating sleeve 403. The hard insulating sleeve 403 movably penetrates the side wall of the mounting frame 300, and the protective tube 404 is fixedly connected to the side wall of the mounting frame 300. The hard insulating sleeve 403 is also provided with an annular flange 405 on the outside, and a reset spring 406 is connected between the end face of the annular flange 405 and the protective tube 404; in the natural state, when the reset spring 406 is not subjected to the external force of the system, the distance between the two conductive plugs 401 is greater than the length of the circuit breaker. That is, as the chain plate conveyor belt 102 operates, the circuit breaker can smoothly enter between the two conductive plugs 401.
[0052] Arched plates 104 are symmetrically arranged on both sides of the top surface of the frame 101. The two arched plates 104 are narrow in the middle and wide at both ends. When the outer ends of the two hard insulating sleeves 403 abut against the two end portions of the arched plates 104, the distance between the two conductive plug rods 401 is greater than the width of the circuit breaker to be tested; when the outer ends of the two hard insulating sleeves 403 abut against the middle portion of the arched plates 104, the inner ends of the conductive plug rods 401 can be inserted into the wiring jack of the circuit breaker to be tested; specifically, rollers 407 are arranged at the outer ends of the hard insulating sleeves 403, and the rollers 407 roll and fit with the inner surfaces of the arched plates 104. When the mounting frame 300 moves from one end of the two arched plates 104 to the other end, the rollers 407 can roll along the arched plates 104, thereby making the two conductive plug rods 401 approach each other first and then move away from each other, so that the conductive plug rods 401 are first inserted into the wiring jack of the circuit breaker and then pulled out.
[0053] It is worth mentioning that when the wiring post 302 is located inside the inclined section 1032, the distance between the two conductive plug rods 401 is greater than the length of the circuit breaker. That is, when the wiring post 302 enters the inclined section 1032 from the horizontal section 1031, the roller 407 has entered the end position of the arch plate 104. At this time, when the two abutting rods 301 move away from each other and separate from the accommodating portion 202, the mounting frame 300 no longer moves forward synchronously with the accommodating portion 202.
[0054] In addition, mounting blocks 105 are provided on both sides of the top surface of the rack 101, and a push spring 106 is connected between the mounting block 105 and the mounting frame 300. When the mounting frame 300 is not subjected to external force of the system, the push spring 106 is in a compressed state, and the wiring column 302 is located inside the horizontal section 1031 and away from the inclined section 1032. At this time, under the thrust of the push spring 106, the mounting frame 300 is located between the two arched plates 104 and close to the starting end of the chain plate conveyor belt 102, and the roller 407 is in contact with the end position of the arched plate 104, that is, at this time, the distance between the two conductive plugs 401 is greater than the length of the circuit breaker.
[0055] In summary, as the chain plate conveyor belt 102 operates, a number of circuit breakers to be tested sequentially enter the inner side of the mounting frame 300. When a circuit breaker enters the inner side of the mounting frame 300, the accommodating portion 202 will first contact the abutting rod 301, thereby pushing the mounting frame 300 to move synchronously with the accommodating portion 202. When the mounting frame 300 enters the middle part between the two arched plates 104, under the pushing action of the arched plates 104, the two conductive plugging rods 401 are respectively inserted into the jacks at both ends of the circuit breaker, thereby connecting the circuit breaker to be tested to the circuit. Subsequently, under the action of the reset spring 406 and the wiring slot 103, the two conductive rods 401 are first pulled outward, and then the two abutment rods 301 move away from each other and separate from the accommodating portion 202. At this time, the accommodating portion 202 can continue to move with the chain conveyor belt 102, and the mounting frame 300 will return to its original position under the action of the push spring 106 and wait for the next circuit breaker to enter the inside of the mounting frame 300.
[0056] It is worth mentioning that the distance between two adjacent accommodating portions 202 is large enough so that the next circuit breaker will not enter between the two arched plates 104 before the mounting frame 300 is reset.
[0057] In another embodiment of the present application, a wrench mechanism 600 is further included. The wrench mechanism 600 is arranged on the top surface of the mounting frame 300. The wrench mechanism 600 is used to push the top handle of the circuit breaker to be tested to open or close. The wrench mechanism 600 includes a displacement portion 601, and the displacement portion 601 is slidably matched with the top wall of the mounting frame 300. Push rods 602 are provided on both sides of the bottom surface of the displacement portion 601. When the circuit breaker to be tested moves to the inside of the mounting frame 300, the top handle of the circuit breaker is located between the two push rods 602. When the displacement portion 601 moves left and right, the handle of the circuit breaker can be pushed by the two push rods 602 to close or open it.
[0058] The specific structure of the wrench mechanism 600 is described below:
[0059] The wrench mechanism 600 also includes a driving screw 603, which is threadedly connected to the displacement part 601. Both ends of the driving screw 603 penetrate the two side walls of the mounting frame 300 and are rotatably connected to the mounting frame 300. One end of the driving screw 603 is provided with a driven pulley 604. A rotating shaft is rotatably provided at the bottom of one side wall of the mounting frame 300. The rotating shaft is rotatably connected to the side wall of the mounting frame 300 through a damping bearing. A driving pulley 605 and a driving gear 606 are fixedly mounted on the rotating shaft. The driving pulley 605 and the driven pulley 604 are connected through a synchronous belt. Therefore, when an external force drives the driving gear 606 to rotate, the displacement part 601 can be controlled to move left and right. When there is no external force driving, the stability of the driving gear 606 can also be ensured due to the provision of the damping bearing.
[0060] In addition, a first rack 107 and a second rack 108 are provided on the inner surface of one of the arched plates 104. The first rack 107 and the second rack 108 are both arranged in the middle part of the arched plate 104. The first rack 107 and the second rack 108 are staggered in the upper and lower positions. When the driving gear 606 passes over the first rack 107 and the second rack 108 respectively, the movement direction of the displacement portion 601 is opposite; when the driving gear 606 passes over the top of the first rack 107, one of the push rods 602 can push the circuit breaker handle to close the circuit breaker; when the driving gear 606 passes under the second rack 108, the other push rod 602 can push the circuit breaker handle to open the circuit breaker.
[0061] It should be noted that, in the initial state, the circuit breakers to be tested are all in the open state, and the orientation of the circuit breakers placed in the accommodating portion 202 is fixed. When the mounting frame 300 passes between the two arched plates 104, under the alternating action of the first rack 107 and the second rack 108, the wrench mechanism 600 closes and then opens the circuit breaker in turn, thereby detecting the current values in the closed and open states to determine whether the circuit breaker can be used normally.
[0062] In summary, in the actual application of this embodiment, when the circuit breaker to be tested enters the inner side of the mounting frame 300, and the mounting frame 300 moves synchronously with the accommodating portion 202, when the active gear 606 passes through the first rack 107, the push rod 602 pushes the top handle of the circuit breaker to make it move to one side, thereby closing the circuit breaker. At this time, the current sensor 402 is used to detect whether the current in the circuit is a standard value. If not, the controller triggers the test production line 100 to stop moving. When the active rack 606 passes through the second rack 108, the push rod 602 pushes the top handle of the circuit breaker to move to the other side, thereby opening the circuit breaker. At this time, the detection value of the current sensor 402 should be 0. If not, the controller also triggers the test production line 100 to stop moving, thereby reminding the staff to pay attention.
[0063] Therefore, this embodiment can automatically realize the wiring, unplugging and testing operations of the circuit breaker without human intervention, which greatly improves the work efficiency and reduces the labor intensity of workers.
