Description

Technical Field

[0001] The present invention relates to the field of automation, and particularly to a detection device for a circuit breaker. Background Art

[0002] Circuit breakers are used for circuit control and protection and have been widely applied. Especially for circuit breakers used for motor protection, after being assembled, they can be sold only after passing the inspection. However, the existing detection devices for circuit breakers have low automation levels, with low detection efficiency and large limitations.

[0003] Especially, when a circuit breaker needs to be connected to a test power supply for testing, after the test power supply causes the circuit breaker to heat up, it will affect the detection of the circuit breaker at the next station. Therefore, it is often necessary to cool the circuit breaker, which not only takes a long time but also requires a large space for the station used to cool the circuit breaker. Summary of the Invention

[0025] Preferably, the two clamping mechanisms respectively include clamping cylinders fixed on one side of the vertical plate, clamping members and guide blocks respectively connected to their respective clamping cylinders.

[0042] like Figure 1-2 The present invention shows two series of circuit breakers for testing, both of which are motor protection circuit breakers, each comprising a housing 1 and wiring terminals 2 respectively arranged at both ends of the housing 1, a handle 3 and an adjusting screw 4 are arranged in the middle of the housing 1, and the difference is that Figure 1 The handle 3 is a button, Figure 2 The handle 3 is a knob.

[0043] The main circuit of the circuit breaker is connected to the circuit through the wiring terminals 2 at both ends. The handle 3 can connect and disconnect the main circuit of the circuit breaker through the operating mechanism. The operating mechanism can trip when a circuit fault occurs, so that the main circuit of the circuit breaker is disconnected. The adjusting screw 4 can change the tripping position of the operating mechanism and compensate for the travel of the operating mechanism to the tripping position, such as the influence of air pressure and temperature on the operating mechanism, so that the circuit breaker can adapt to the actual working environment after leaving the factory and ensure that the circuit breaker can be accurately tripped.

[0044] The following is combined with Figures 3 to 5 The given examples further illustrate the specific implementation of the circuit breaker detection device created by the present invention. The circuit breaker detection device created by the present invention is not limited to the description of the following examples.

[0045] As Figure 3-5 shown, the detection device for the circuit breaker of the present invention includes a transportation device, a screw-removing device 100, a large-position closing device 200, a large-and-small-position detection device 300, a small-position closing device 400, a power-on / off testing device 600, and a discharging device 700. The transportation device drives the circuit breaker to pass through the screw-removing device 100, the large-position closing device 200, the large-and-small-position detection device 300, the small-position closing device 400, the large-and-small-position detection device 300, the power-on / off testing device 600, and the discharging device 700 in sequence. The screw-removing device 100 removes the screws of the terminal 2 of the circuit breaker, so that the wiring screws of the terminal are withdrawn from the wiring base by a part, facilitating the subsequent insertion of the electrodes for connecting the test power supply into the wiring base for connection;

[0046] The large-position closing device 200 presses or rotates the handle 3 of the circuit breaker to make the circuit breaker close for the first time;

[0047] The large-and-small-position detection device 300 connects the circuit breaker that has been closed for the first time by the large-position closing device 200 to the first test power supply, screws the adjusting screw 4 of the circuit breaker until the circuit breaker trips for the first time, and records the angle through which the adjusting screw 4 rotates;

[0048] The small-position closing device 400 presses or rotates the handle 3 of the circuit breaker to make the circuit breaker close for the second time; that is, the large-position closing device 200 and the small-position closing device 400 respectively operate the handle 3 of the circuit breaker to make the circuit breaker close respectively in sequence;

[0049] The large-and-small-position detection device 300 connects the circuit breaker that has been closed for the second time by the small-position closing device 400 to the second test power supply, screws the adjusting screw 4 of the circuit breaker until the circuit breaker trips for the second time, and records the angle through which the adjusting screw 4 rotates; that is, the circuit breaker passes through the large-and-small-position detection device 300 respectively after each closing, and the first test power supply is different from the second test power supply;

[0050] The power-on / off testing device 600 connects the circuit breaker to the third test power supply, and presses or rotates the handle 3 of the circuit breaker to detect whether the handle 3 can conduct and disconnect the circuit breaker;

[0051] The discharging device 700 takes out the circuit breaker that has completed the detection from the transportation device.

[0052] For the detection device of the circuit breaker of the present invention, first, the large-and-small-position detection device 300 screws the adjusting screw 4 of the circuit breaker after two closings, so that the circuit breaker after two closings trips respectively, and measures whether the angles through which the adjusting screw 4 rotates during the two trips of the large and small positions are within a certain range. Then, the power-on / off testing device 600 detects whether the handle 3 can conduct and disconnect the circuit breaker, which can quickly and accurately automatically detect the circuit breaker, thereby reducing the labor cost.

[0053] Further, it further includes a laser marking device 500 which is used to print marks on the circuit breaker. The laser marking device 500 can be arranged at any position within the detection device. In one embodiment, the laser marking device 500 is arranged before the power-on / off testing device 600. The transportation device sends the circuit breaker after the second tripping by the size detection device 300 to the laser marking device 500 for printing first, and then to the power-on / off testing device 600 for detection. It can effectively cool the circuit breaker while printing marks on the circuit breaker, preventing the circuit breaker from being directly sent to the power-on / off testing device 600 for detection in a high-temperature state.

[0054] As Figure 3-5 shown, this embodiment includes 16 size detection devices 300. The transportation device includes a main conveyor belt 810, an intermediate conveyor belt 820 and an intermediate handling device 830. The 16 size detection devices are correspondingly arranged with the intermediate handling device 830. The main conveyor belt 810 and the intermediate conveyor belt 820 respectively drive the circuit breaker through the intermediate handling device 830, and the intermediate handling device 830 transports the circuit breaker between the main conveyor belt 810, the intermediate conveyor belt 820 and the 16 size detection devices 300.

[0055] The main conveyor belt 810 cooperates with the screw removal device 100, the large-size closing device 200, the intermediate handling device 830, the laser marking device 500, the power-on / off testing device 600 and the discharging device 700.

[0056] The intermediate conveyor belt 820 cooperates with the small-size closing device 400 and the intermediate handling device 830.

[0057] When the circuit breakers on the main conveyor belt 810 and the intermediate conveyor belt 820 respectively pass through the intermediate handling device 830, the intermediate handling device 830 selectively transports according to the working steps of the circuit breaker:

[0058] The circuit breaker after the first latching by the large-size closing device 200 is moved by the intermediate handling device 830 to the size detection device 300 for the first tripping.

[0059] The circuit breaker after the first tripping by the size detection device 300 is moved by the intermediate handling device 830 to the intermediate conveyor belt 820, and the intermediate conveyor belt 820 drives the circuit breaker through the small-size closing device 400 for the second latching.

[0060] The circuit breaker after the second latching by the small-size closing device 400 is moved again by the intermediate handling device 830 to the size detection device 300 for the second tripping.

[0061] After the circuit breaker has tripped for the second time by the large and small gear detection device 300, it is moved to the main conveyor belt 810 by the intermediate handling device 830. The main conveyor belt 810 drives the circuit breaker to pass through the laser marking device 500, the live test on-off device 600, and the discharging device 700 in sequence.

[0062] The working steps of all circuit breakers can be determined according to the positions of the circuit breakers on each device of the transportation equipment and the detection equipment. For example, the circuit breaker on the large gear closing device 200 is next moved to the large and small gear detection device 300, and then sequentially moved to the intermediate handling device 830, the small gear closing device 400, the next large and small gear detection device 300, and the main conveyor belt 810. In addition, the working steps of all circuit breakers can also be queried in the control system by scanning the bar code on the circuit breaker housing, or can be selected by other means.

[0063] In the transportation equipment of this embodiment, the circuit breaker is transported by the main conveyor belt 810 and the intermediate conveyor belt 820 respectively, and then the circuit breaker is handled by the intermediate handling device 830. The intermediate conveyor belt 820 can also play a role in cooling the circuit breaker during the transportation process, and the intermediate handling device 830 can selectively handle according to the working steps of the circuit breaker, and move different circuit breakers to the devices corresponding to the next working step respectively, so as to meet the rhythm of the operation of the entire equipment. Of course, the number of the large and small gear detection devices 300 can also be adjusted, and the number of the large and small gear detection devices 300 is not specifically limited here.

[0064] Furthermore, the intermediate conveyor belt 820 is annular, and 16 large and small gear detection devices 300 are arranged on the inner side of the intermediate conveyor belt 820. The intermediate conveyor belt 820 first transports the circuit breaker that has tripped for the first time by the large and small gear detection device 300 away from the small gear closing device 400, and then moves to the small gear closing device 400 after the circuit breaker has traveled at least one lap of the intermediate conveyor belt 820. The annular intermediate conveyor belt 820 can not only cool the circuit breaker while transporting it, but also has the characteristic of small floor area. This is the preferred embodiment of the present invention. Of course, the intermediate conveyor belt 820 can also be in a linear structure or other shapes, which all belong to the protection scope of the present invention.

[0065] Specifically, the intermediate conveyor belt 820 is rectangular. The intermediate conveyor belt 820 includes a first conveyor section 821, a second conveyor section 822, a third conveyor section 823, and a fourth conveyor section 824 that are connected end to end in sequence. The first conveyor section 821 is arranged parallel to the third conveyor section 823, and the second conveyor section 822 is arranged parallel to the fourth conveyor section 824. The circuit breaker moves in sequence along the directions of the first conveyor section 821, the second conveyor section 822, the third conveyor section 823, and the fourth conveyor section 824;

[0066] The main conveyor belt 810 is arranged in a linear structure parallel to the side of the first conveyor section 821 away from the third conveyor section 823, and the moving direction of the main conveyor belt 810 is opposite to that of the first conveyor section 821 for driving the circuit breaker;

[0067] The 16 size detection devices 300 and the small-size closing device 400 are respectively arranged on the side of the first conveyor section 821 away from the main conveyor belt 810. The intermediate handling device 830 is arranged on the side of the main conveyor belt 810 away from the first conveyor section 821 corresponding to the 16 size detection devices 300, and the detection rhythm is improved by the 16 size detection devices 300.

[0068] Among them, the 16 size detection devices 300 are arranged at one end of the first conveyor section 821 close to the second conveyor section 822, and the small-size closing device 400 is adjacently arranged at one end of the first conveyor section 821 close to the fourth conveyor section 824. That is to say, the small-size closing device 400 is arranged on one side of the 16 size detection devices 300 in the direction opposite to that of the first conveyor section 821. After the circuit breaker is first tripped by the 16 size detection devices 300 and placed on the first conveyor section 821 through the intermediate handling device 830, it then passes through the second conveyor section 822, the third conveyor section 823, and the fourth conveyor section 824 in sequence, and is cooled and then moved to the small-size closing device 400 for the second closing.

[0069] The intermediate conveyor belt 820 is rectangular, which can make the first conveyor section 821 and the main conveyor belt 810 parallel to each other and arranged between the 16 size detection devices 300 and the intermediate handling device 830. While transporting the circuit breaker over a long distance through the intermediate conveyor belt 820, it can also concentrate the circuit breakers to be handled together, facilitating the intermediate handling device 830 to handle the circuit breakers.

[0070] As Figure 6 shown, the intermediate handling device 830 includes an intermediate slide rail 831 arranged parallel to the main conveyor belt 810, and a manipulator 832 slidably engaged on the intermediate slide rail 831. An intermediate transverse movement cylinder 833 connected to the bottom of the manipulator 832 is arranged on the intermediate slide rail 831. The manipulator 832 is a multi-axis manipulator driven by multiple motors in the prior art. When grasping the circuit breaker, it first drives the picking mechanism to move above the main conveyor belt 810 and the intermediate conveyor belt 820 to block the movement of the circuit breaker along with the main conveyor belt 810 and the intermediate conveyor belt 820, and then grasps the circuit breaker. Of course, the manipulator 832 can also be a combination of a clamping jaw cylinder and multiple rotary cylinders, transverse movement cylinders, and vertical movement cylinders, or a combination of multiple motors, which all fall within the protection scope of the present invention.

[0071] As Figures 10-11As shown in the figure, the transportation device further includes a plurality of fixing devices 840. All devices other than the size detection device 300 in this embodiment are arranged above the transportation device. The fixing device 840 can fix the circuit breaker on the transportation device, prevent the circuit breaker from moving with the transportation device, facilitate the detection of the circuit breaker, and eliminate the need to carry the circuit breaker. After the detection is completed, the fixing device 840 resets to release the circuit breaker.

[0072] The plurality of fixing devices 840 are respectively arranged corresponding to the screw removal device 100, the large gear closing device 200, the small gear closing device 400, the laser marking device 500, the power-on / off test device 600, and the discharging device 700. The fixing device 840 corresponding to the small gear closing device 400 cooperates with the intermediate conveyor belt 820, and the fixing devices 840 corresponding to the screw removal device 100, the large gear closing device 200, the laser marking device 500, the power-on / off test device 600, and the discharging device 700 cooperate with the main conveyor belt 810. The principle of fixing the circuit breaker is the same, but the circuit breaker is fixed at different positions on the transportation device.

[0073] Specifically, the fixing device 840 includes a front material blocking mechanism 841, a rear material blocking mechanism 842, and a material lifting mechanism 843. The front material blocking mechanism 841 and the rear material blocking mechanism 842 are arranged on the side of the transportation device, and the material lifting mechanism 843 is arranged at a position corresponding to the middle between the front material blocking mechanism 841 and the rear material blocking mechanism 842 at the bottom of the transportation device. The front material blocking mechanism 841 and the rear material blocking mechanism 842 can respectively extend above the transportation device to block and avoid the circuit breaker. The circuit breaker after being avoided by the rear material blocking mechanism 842 is first blocked by the front material blocking mechanism 841, and then fixed on the transportation device by the material lifting mechanism 843. After the detection is completed, the material lifting mechanism 843 resets, and the front material blocking mechanism 841 avoids the circuit breaker and then resets to block the next circuit breaker avoided by the rear material blocking mechanism 842.

[0074] Refer to Figure 9 , in this embodiment, the front material blocking mechanism 841 and the rear material blocking mechanism 842 respectively include a material blocking transverse cylinder and a material blocking rod connected to the material blocking transverse cylinder. The material blocking transverse cylinder can drive the material blocking rod to extend to and away from above the transportation device. Preferably, it further includes a pre-material blocking mechanism 844. The pre-material blocking mechanism 844 is arranged on the side of the rear material blocking mechanism 842 away from the front material blocking mechanism 841, which can reduce the difficulty of the rear material blocking mechanism 842 releasing the circuit breaker one by one.

[0075] Refer to Figure 9, the working principle of the ejecting mechanism 843 in this embodiment is that the lateral length of the circuit breaker is less than the width of the conveyor belt on the transportation device, and the bottoms at both ends of the circuit breaker are exposed from the transportation device. The ejecting mechanism 843 includes two ejecting rods 8431 oppositely arranged on both sides of the transportation device, and two inclined ejecting blocks 8432 respectively cooperating with the two ejecting rods 8431. The two inclined ejecting blocks 8432 are respectively connected to an inclined ejecting transverse cylinder 8433. The top side of the inclined ejecting block 8432 is provided with an inclined ejecting surface, and the bottom side of the ejecting rod 8431 is slidably engaged with the ejecting surface. The inclined ejecting transverse cylinder 8433 can drive the inclined ejecting block 8432 to move laterally, and drive the ejecting rod 8431 to move upward through the ejecting surface of the inclined ejecting block 8432 to eject the circuit breaker from the transportation device.

[0076] The ejecting mechanism 843 in this embodiment can not only fix the circuit breaker, but also shorten the distance between the circuit breaker and the detection device. In addition, it can also avoid friction between the circuit breaker and the transportation device.

[0077] It can be understood that the front material blocking mechanism 841, the rear material blocking mechanism 842, the ejecting mechanism 843 and the pre-material blocking mechanism 844 can also press the circuit breaker against the guardrail on the side of the transportation device by pushing the circuit breaker from the side, but this will cause friction between the bottom of the circuit breaker and the transportation device, and all belong to the protection scope of the present invention.

[0078] As Figures 7-8 A preferred embodiment of the size detection device 300 is shown. The 16 size detection devices 300 have the same structure and are respectively fixed on the side of the vertical plate 301. The vertical plate 301 is arranged in the middle of the middle conveyor belt 820 and is perpendicular to the plane where the middle conveyor belt 820 is located. The size detection device 300 includes two oppositely arranged clamping mechanisms 310, and a screwing mechanism 320 arranged on the side between the two clamping mechanisms 310. The two clamping mechanisms 310 are respectively connected to two test electrodes 330. While clamping the circuit breaker from both sides, the test electrodes 330 are inserted into the circuit breaker connected to the wiring terminal 2, and then the adjusting screw 4 of the circuit breaker is rotated by the screwing mechanism 320.

[0079] Specifically, the two clamping mechanisms 310 respectively include clamping cylinders 311 fixed on one side of the vertical plate 301, and clamping members 312 and guide blocks 313 respectively connected to their respective clamping cylinders 311. A guide plate 332 is provided on the side of the vertical plate 301 away from the two clamping cylinders 311. The guide plate 332 is connected to the vertical plate 301 through a clamping transverse movement cylinder 331. The two test electrodes 330 pass through the vertical plate 301 and are respectively matched with the guide plate 332 and the corresponding guide blocks 313 at both ends. The guide blocks 313 are provided with horizontal holes in the horizontal direction. The test electrodes 330 pass through the horizontal holes and are longitudinally limitedly matched with the guide blocks 313. The test electrodes 330 slide along the horizontal holes under the drive of the guide plate 332. The guide plate 332 is provided with vertical holes in the longitudinal direction. The test electrodes 330 slide along the vertical holes under the drive of the guide blocks 313. After the test electrodes 330 pass through the vertical holes, they are connected to the limiting plates 334 on both sides of the guide plate 332. The test electrodes 330 are transversely limitedly matched with the guide plate 332 through the limiting plates 334.

[0080] While the two clamping cylinders 311 drive the two clamping members 312 to approach each other to fix the circuit breaker, the corresponding test electrodes 330 are driven by the two guide blocks 313 to be inserted into the circuit breaker. After the test electrodes 330 are inserted into the circuit breaker, the clamping transverse movement cylinder 331 drives the two test electrodes 330 to push the connection terminals 2 of the circuit breaker towards the vertical plate 301 through the guide plate 332.

[0081] When the clamping member 312 fixes the circuit breaker, the test electrode 330 is driven by the guide block 313, and at the same time, the test electrode 330 is connected to the connection terminal 2. There is no need to set an additional cylinder to drive the test electrode 330, nor is there a need to wait for an additional time. In addition, the transverse movement cylinder 331 drives the test electrode 330 to push the connection terminal 2 of the circuit breaker towards the vertical plate 301. This can not only make the test electrode 330 reliably pressed on the connection terminal 2, but also press the circuit breaker on the vertical plate 301 at the same time. There is no need to set an additional cylinder to horizontally position the circuit breaker, nor is there a need to wait for an additional time. This effectively reduces the number of parts, lowers the cost, and improves the efficiency. Of course, two clamping transverse movement cylinders 331 and two guide plates 332 can also be set. The two clamping transverse movement cylinders 331 respectively drive the two test electrodes 330 to move through the two guide plates 332, which all fall within the protection scope of the present invention.

[0082] Further, the screwing mechanism 320 includes a screwing transverse translation cylinder 321 vertically arranged with respect to the vertical plate 301, a screwing adjustment cylinder 322 connected to the screwing transverse translation cylinder 321 and horizontally arranged with respect to the vertical plate 301, a screwing rotation motor 323 connected to the screwing adjustment cylinder 322, and a screwdriver 324 connected to the screwing rotation motor 323. The screwing adjustment cylinder 322 drives the screwdriver 324 to move in a direction parallel to the vertical plate 301, that is, horizontally, vertically, or in a direction inclined to the horizontal and vertical directions, so that the screwdriver 324 aligns with the adjustment screw 4. The screwing transverse translation cylinder 321 drives the screwdriver 324 to move horizontally closer to the adjustment screw 4, and the screwing rotation motor 323 drives the screwdriver 324 to screw the adjustment screw 4.

[0083] The angle through which the adjustment screw 4 rotates can be counted in various ways. For example, it can be cooperated with the screwdriver 324 through a travel switch, or the energization time of the screwing rotation motor 323 can be recorded. When the screwing rotation motor 323 operates, the initial position of the adjustment screw 4 is recorded. When the circuit breaker trips, the circuit breaker automatically disconnects the first test power supply or the second test power supply connected by the two test electrodes 330. According to the signals of the two test electrodes 330, the end position of the adjustment screw 4 is recorded, and then the angle through which the adjustment screw 4 rotates is calculated by comparing with the initial position of the adjustment screw 4, which all fall within the protection scope of the invention. The voltages and currents of the first test power supply or the second test power supply are different, and they can be provided by a power supply device or by different power supply devices.

[0084] The position of the adjustment screw 4 on the housing 1 of the circuit breaker is fixed. However, for different types of circuit breakers, the screwing adjustment cylinder 322 can drive the screwdriver 324 to move so that the screwdriver 324 can align with the adjustment screw 4. The wiring screws 4 of the two circuit breakers in this embodiment are only different in the longitudinal position after being fixed by the clamping mechanism 310. Therefore, the screwing adjustment cylinder 322 drives the screwdriver 324 to move longitudinally to align. It can be understood that the screwing adjustment cylinder 322 can also drive the screwdriver 324 to move horizontally or obliquely, which all fall within the protection scope of the present invention.

[0085] The working process of the size detection device 300 in this embodiment includes the following steps:

[0086] S1: The manipulator 832 of the intermediate handling device 830 grabs the circuit breaker and places it between the two clamping mechanisms 310 of the size detection device 300. The clamping cylinders 311 of the two clamping mechanisms 310 move towards the middle at the same time, so that while the clamping members 312 clamp the circuit breaker, the test electrodes 330 are inserted into the circuit breaker;

[0087] S2: The clamping and transverse movement cylinder 331 moves backward, driving the test electrode 330 to push the wiring terminal 2 of the circuit breaker towards the vertical plate 301, ensuring reliable contact between the test electrode 330 and the wiring terminal 2, and firmly fixing the circuit breaker on the vertical plate 301;

[0088] S3: The screwing adjustment cylinder 322 adjusts the position of the screwdriver 324 according to the type of the current circuit breaker and the type of the circuit breaker detected last time. If they are different, the screwing adjustment cylinder 322 drives the screwdriver 324 to move and adjust the position so that the screwdriver 324 aligns with the adjustment screw 4; if they are the same, this step is skipped, the screwing adjustment cylinder 322 does not act, and the screwdriver 324 automatically aligns with the adjustment screw 4;

[0089] S4: The screwing transverse movement cylinder 321 drives the screwdriver 324 to move laterally closer to the adjustment screw 4;

[0090] S5: Adjust the large and small gears to trip the circuit breaker. The test electrode 330 conducts tests according to the parameters of the preset first test power supply or the second test power supply. The screwing rotary motor 323 drives the adjustment screw 4 to rotate through the screwdriver 324 until the circuit breaker trips. At this time, the circuit breaker disconnects between the test electrodes 330. Record the angle turned by the adjustment screw 4. If the angle turned by the adjustment screw 4 is not within the predetermined range, it means the circuit breaker is unqualified. If the angle turned by the adjustment screw 4 is within the predetermined range, it means the circuit breaker is qualified;

[0091] S6: The screwing transverse movement cylinder 321 resets, and the screwdriver 324 is ready to retrieve the circuit breaker;

[0092] S7: The manipulator 832 takes out the circuit breaker in the large and small gear detection device 300 and sends the circuit breaker to the corresponding position in the next step according to the number of times the circuit breaker trips. If step S5 is the first trip of the circuit breaker, the circuit breaker is moved to the intermediate conveyor belt 820, cooled by the intermediate conveyor belt 820, and prepared for the second closing; if step S5 is the second trip of the circuit breaker, the circuit breaker is moved to the main conveyor belt 810 and sent to the laser marking device 500 through the main conveyor belt 810.

[0093] Such as Figures 9-10Shows a preferred embodiment of the large - gear closing device 200 and the small - gear closing device 400. The structures of the large - gear closing device 200 and the small - gear closing device 400 are the same. The large - gear closing device 200 and the small - gear closing device 400 respectively include a rotary operating mechanism 210 and a pressing operating mechanism 220. The rotary operating mechanism 210 and the pressing operating mechanism 220 are respectively used for closing the circuit breaker with a knob as the handle 3 and for closing the circuit breaker with a button as the handle 3. The rotary operating mechanism 210 and the pressing operating mechanism 220 are respectively connected to an operating transverse translation cylinder 230. The operating transverse translation cylinder 230 is connected to an operating vertical translation cylinder 240. According to the type of the handle 3, the operating transverse translation cylinder 230 drives the rotary operating mechanism 210 to move above the knob or drives the pressing operating mechanism 220 to move above the button. Then the operating transverse translation cylinder 230 drives the rotary operating mechanism 210 or the pressing operating mechanism 220 to move downward to close the circuit breaker.

[0094] In this embodiment, the pressing operating mechanism 220 is a push rod arranged longitudinally. When closing, the operating vertical translation cylinder 240 drives the push rod to move to the pressing position at the top of the button, and then the operating transverse translation cylinder 230 drives the push rod to press the button to directly close the circuit breaker.

[0095] The rotary operating mechanism 210 of this embodiment includes a rack transverse translation cylinder 211, a rack 212 connected to the rack transverse translation cylinder 211, a gear 213 meshing with the rack 212, and a rotating cylinder 214 connected to the gear 213. When closing, the operating vertical translation cylinder 240 drives the rotating cylinder 214 to move above the button knob. Then the operating transverse translation cylinder 230 drives the rotating cylinder 214 to move downward and sleeve on the knob. The rack transverse translation cylinder 211 drives the rack 212 to move horizontally, driving the gear 213 to drive the rotating cylinder 214 to rotate, so as to close the circuit breaker. Of course, the rack transverse translation cylinder 211, the rack 212 and the gear 213 can also be replaced by a rotary cylinder, directly driving the rotating cylinder 214 to rotate by the rotary cylinder, but a larger torque is required. In addition, two large - gear closing devices 200 and two small - gear closing devices 400 can also be provided respectively. The two large - gear closing devices 200 are respectively provided with a rotary operating mechanism 210 and a pressing operating mechanism 220. The same is true for the two small - gear closing devices 400, which are only used to close the circuit breakers corresponding to the handle 3, and all belong to the protection scope of the present invention.

[0096] For the large - gear closing device 200 and the small - gear closing device 400 of this embodiment, the operating vertical translation cylinder 240 drives the corresponding rotary operating mechanism 210 of the knob or the corresponding pressing operating mechanism 220 of the button to move above the handle 3 according to the type of the handle 3, and can be applicable to the detection of at least two types of circuit breakers.

[0097] Such as Figure 11Shows a preferred embodiment of the live test switch device 600. The working principle of the live test switch device 600 is the same as that of the large gear closing device 200 and the small gear closing device 400. However, the live test switch device 600 connects the circuit breaker to the third test power supply and detects the current change of the circuit breaker while operating the circuit breaker.

[0098] This embodiment includes two live test switch devices 600. The two live test switch devices 600 perform live test switch detection using the live test switch device 600 with a rotary operating mechanism 210 or the live test switch device 600 with a pressing operating mechanism 220 according to the handle type of the detected circuit breaker. The two live test switch devices 600 are respectively the rotary switch device 610 and the pressing switch device 620, which respectively include a rotary operating mechanism 210 and a pressing operating mechanism 220, and live test electrodes 630 correspondingly arranged on both sides of their respective rotary operating mechanisms 210 and pressing operating mechanisms 220. The live test electrodes 630 are connected to the operating vertical translation cylinder 240. The rotary operating mechanism 210 and the pressing operating mechanism 220 are respectively used to operate the handle 3 with a knob and the handle 3 with a button. The circuit breaker passes through the two live test switch devices 600 in sequence, and the live test switch device 600 with a rotary operating mechanism 210 or a pressing operating mechanism 220 corresponding to the knob or button of the handle 3 acts, and the other live test switch device 600 does not act. Since one live test switch device 600 does not include both a rotary operating mechanism 210 and a pressing operating mechanism 220 at the same time, it is not necessary to operate the horizontal translation cylinder 230 to select the circuit breaker corresponding to the handle 3. It can be understood that only one live test switch device 600 can also be provided. The live test switch device 600 includes both a rotary operating mechanism 210 and a pressing operating mechanism 220 at the same time, that is, it has the same structure as the large gear closing device 200 and the small gear closing device 400, but it is necessary to add the live test electrode 630 and the cylinder for driving the live test electrode 630 to insert into the circuit breaker.

[0099] The working processes of the large gear closing device 200 and the small gear closing device 400 in this embodiment are the same. Taking the large gear closing device 200 as an example, the working steps of the large gear closing device 200 are described as follows:

[0100] S1: The circuit breaker is fixed below the large gear closing device 200 by the corresponding fixing device 840;

[0101] S2: The operating horizontal translation cylinder 230 selects the rotary operating mechanism 210 and the pressing operating mechanism 220 according to the circuit breaker handle 3. If the handle 3 is a knob, the rotary operating mechanism 210 drives the rotary operating mechanism 210 to move above the knob. If the handle 3 is a button, the rotary operating mechanism 210 drives the pressing operating mechanism 220 to move above the button;

[0102] S3: Operate the vertical translation cylinder 240 to drive the rotary operating mechanism 210 and the pressing operating mechanism 220 downward, so that the rotary operating mechanism 210 is buckled on the knob, or the pressing operating mechanism 220 directly presses the button to achieve buckling;

[0103] S4: The circuit breaker of the button skips this step. The circuit breaker of the knob moves through the rack horizontal translation cylinder 211 of the rotary operating mechanism 210, so that the rotary operating mechanism 210 drives the knob to rotate and buckle;

[0104] S5: Operate the vertical translation cylinder 240, the horizontal translation cylinder 230 and the rotary operating mechanism 210 to reset in sequence.

[0105] As Figure 10 shown in the preferred embodiment of the screw removal device 100, the screw removal device 100 includes three groups of rotary cylinders and screwdrivers respectively connected to the rotary cylinders. The three groups of screwdrivers remove screws in two working steps. Three wiring terminals 2 are respectively provided at both ends of the circuit breaker. In the first working step, two screwdrivers are used to remove the two outermost wiring terminals 2 at each end. In the second working step, one screwdriver is used to remove the middle wiring terminal 2 at each end.

[0106] As Figure 11 shown in the preferred embodiment of the discharging device 700, the discharging device 700 includes a discharging jaw cylinder 710, a discharging vertical translation cylinder 720 connected to the discharging jaw cylinder 710, and a discharging horizontal translation cylinder 730 connected to the discharging vertical translation cylinder 720. The discharging jaw cylinder 710 takes out the circuit breaker that has been detected, and the discharging vertical translation cylinder 720 and the discharging horizontal translation cylinder 730 drive the circuit breaker to move to the qualified position or the unqualified position.

[0107] The laser marking device 500 in this embodiment is prior art. The fixing device 840 fixes the circuit breaker on the transportation equipment below the laser marking device 500, and the laser marking device 500 prints on the housing. The laser marking device 500 in this embodiment is arranged before the power-on and power-off testing device 600. The circuit breaker after the second buckling by the size detection device 300 is first sent to the laser marking device 500 for printing, and then sent to the power-on and power-off testing device 600 for detection. While the circuit breaker is being printed by the laser marking device 500, it can also be cooled to avoid waiting.

[0108] All the cylinders mentioned in the present invention can also be motors or oil cylinders, which all belong to the protection scope of the present invention. In addition, sensors are provided on all cylinders or motors to detect the action states of the cylinders or motors, and drive the reset after the cylinders or motors reach the action positions.

[0109] The overall working process of the circuit breaker detection equipment in this embodiment is as follows:

[0110] For the assembled circuit breaker, the main conveyor belt 810 moves the circuit breaker under the screw-removing device 100. The screw-removing device 100 removes the wiring screws of the wiring terminal 2 of the circuit breaker in two working steps.

[0111] The main conveyor belt 810 moves the circuit breaker to the large-block closing device 200. The large-block closing device 200 uses different closing methods according to different series of circuit breakers to make the circuit breaker close for the first time.

[0112] For the circuit breaker after the first closing, it is moved to one side of the intermediate handling device 830 by the main conveyor belt 810. The intermediate handling device 830 sends the circuit breaker to the large and small block detection device 300 for large block detection, making the circuit breaker trip for the first time.

[0113] For the circuit breaker after large block detection, it is moved to the intermediate conveyor belt 820 by the intermediate handling device 830. The circuit breaker moves through the annular intermediate conveyor belt 820 to the small-block closing device 400, and at the same time, the circuit breaker is cooled after large block detection.

[0114] The small-block closing device 400 is the same as the large-block closing device 200. It uses different closing methods according to different series of circuit breakers to make the circuit breaker close for the second time.

[0115] For the circuit breaker after the second closing, it is moved to one side of the intermediate handling device 830 by the intermediate conveyor belt 820. The intermediate handling device 830 sends the circuit breaker to the large and small block detection device 300 for small block detection, making the circuit breaker trip for the second time.

[0116] For the circuit breaker after small block detection, it is sent to the main conveyor belt 810 by the intermediate handling device 830. The main conveyor belt 810 moves the circuit breaker to the laser marking device 500.

[0117] The laser marking device 500 prints on the circuit breaker and at the same time cools the circuit breaker after small block detection.

[0118] For the circuit breaker after printing, it is successively moved to two test power on / off devices 600 by the main conveyor belt 810. According to whether the circuit breaker is a button or a knob, the two test power on / off devices 600 only detect the corresponding button or knob circuit breakers.

[0119] Finally, the main conveyor belt 810 moves the circuit breaker to the discharging device 700. The discharging device 700 takes out the circuit breaker and moves the circuit breaker to the qualified position or unqualified position according to the detection result.

[0120] The above content is a further detailed description of the present invention creation in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention creation is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention creation belongs, without departing from the concept of the present invention creation, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope of the present invention creation.
