Description

Technical Field

[0001] The present invention relates to the field of bypass switches, and in particular to an automatic detection system for bypass switches. Background Art

[0002] A bypass switch is a common low-voltage electrical appliance, often used for switching between two power sources in important power distribution situations (such as data centers). It ensures that when the main power source fails during the power supply process, it can quickly switch to the backup power source to ensure normal power supply to the load end. At the same time, it ensures that during the inspection and maintenance of the switch itself, the bypass switch can supply power to important loads, realizing uninterrupted power inspection and maintenance.

[0003] Due to the particularity of bypass switch application scenarios, after the bypass switch is prepared, it is necessary to first test the characteristics, resistance, and withstand voltage of the bypass switch to ensure that it passes the test before it can be put into use. The traditional testing method is to manually test the bypass switch using a characteristic tester, a resistance tester, and a withstand voltage tester to ensure that the bypass switch meets the performance requirements. This is very cumbersome and labor-intensive, especially when performing characteristic testing, that is, testing whether the bypass switch is opening and closing normally. This requires toggling the bypass switch to open and close the switch multiple times to complete the test. When the bypass switch is not connected to the power distribution system, it needs to be manually opened and closed. The operator holds a first lever, inserts the first lever into the opening and closing port of the bypass switch, and toggles the first lever to open and close the switch. This testing process requires multiple manual toggling to complete multiple opening and closing tests, which is very cumbersome and requires a lot of manual labor. In addition, manual testing inevitably has adverse effects such as missed detection and false detection, which affects the accuracy of the test results. Summary of the Invention

Through the design of the adjustment holes 438, the position of the cylinder mounting seat 437 can be fine-tuned, and then the distance between the first shift rod cylinder 436 and the first guide plate 431 can be fine-tuned, which is convenient for subsequent driving.

[0083] The first shift rod seat 434 is a U-shaped plate formed by a bottom plate and a pair of side plates connected together, and the bottom plate and side plates of the first shift rod seat 434 are both vertically arranged. The bottom plate of the first shift rod seat 434 is connected to the piston rod of the first shift rod cylinder 436.

[0084] The first lever sleeve 434 is located between the two side panels of the first lever seat 434, and a first lever seat 439 is also mounted on the outer wall of the first lever sleeve 434. The first lever seat 439 is fixed to the first lever sleeve 434 by screws. First lever shafts 440 are connected to both sides of the first lever seat 439. Through holes for the first lever shafts 440 to pass through are respectively opened on the two side panels of the first lever seat 434. A first bearing is also arranged between the first lever shaft 440 and the through hole of the side panel of the first lever seat 434. A through hole for the installation of the first bearing is also opened on the side panel of the first lever seat 434. The two first lever shafts 440 pass through the two guide grooves 433 respectively.

[0085] A first guide trolley 441 is also provided in the guide groove 433. The first guide trolley 441 is also arc-shaped and can move back and forth in the guide groove 433. A through hole is provided on the first guide trolley 441 for the first sleeve shaft 440 to pass through. Second bearings 442 are also connected to both sides of the first guide trolley 441. Bearing mounting shafts 443 for mounting the second bearings 442 are connected to both sides of the first guide trolley 441. The second bearings 442 are directly mounted on the bearing mounting shafts 443. 43, the outer wall of the second bearing 442 fits with the inner wall of the guide groove 433, and a limiting rib 444 for limiting the second bearing 442 is provided on the inner wall of the guide groove 433 on the side close to the first lever seat 434. The limiting ribs 444 of the two guide grooves 433 are used to limit the two first guide trolleys 441 at two different side ends respectively, thereby limiting the moving trajectories of the two first guide trolleys 441 and ensuring that the first lever 407 can swing stably.

[0086] A recess is defined at the bottom end of the first lever sleeve 434 for the insertion and movement of the first lever 407. The first lever 407 is driven to reciprocate by a first push cylinder 435 mounted on the first lever sleeve 434. A cavity is also defined within the first lever sleeve 434 for the insertion and reciprocation of the piston rod of the first push cylinder 435. The piston rod of the first push cylinder 435 is connected to the first lever 407. The design of the first lever mechanism utilizes the coordination of the first lever bracket, the first lever cylinder, the first lever sleeve 434, and the first lever base 434 to achieve the back-and-forth swinging of the first lever 407, ensuring stable swinging of the first lever 407 to open and close the bypass switch and ensure smooth testing.

[0087] The resistance test unit, used to test the resistance of the bypass switch, includes a resistance tester 7 mounted on a characteristic test board 402. The resistance tester 7 rises and falls with the characteristic test board 402, and has several resistance contacts 71 at its bottom. The design of the resistance tester 7, by mounting the resistance tester 7 on the characteristic test board 402, allows the resistance tester 7 to be simultaneously performed on the previous bypass switch while the characteristic tester is performing a characteristic test on the subsequent bypass switch. This reduces testing time and significantly improves testing efficiency.

[0088] The withstand voltage test unit is used to test the withstand voltage performance of the bypass switch, such as Figure 15 、 Figure 16 As shown in the schematic diagram, the pressure test unit includes a pressure test bracket 5, a pressure test push plate 501, and a pressure test assembly.

[0089] The pressure test bracket 5 is installed on the test platform 101. The pressure test bracket 5 includes a pressure test base plate 502, a pressure test column 503, and a pressure test beam 504. There are two pressure test base plates 502, which are distributed in parallel on the test platform 101 along the second direction, and the pressure test base plates 502 are fixed to the test platform 101 by bolts. There is a pair of pressure test columns 503, which are connected to the pressure test base plates 502 one by one, and there is also a pressure test column 503 connected to the pressure test base plates 502. The first pressure-resistant reinforcement plate 505 is used to strengthen the stability of the connection between the pressure-resistant test column 503 and the pressure-resistant test base plate 502. A pressure-resistant test beam 504 is connected to the top of the two pressure-resistant test columns 503. A pair of second pressure-resistant reinforcement plates 506 are also connected between the pressure-resistant test beam 504, the pressure-resistant test column 503, and the pressure-resistant test base plate 502, thereby strengthening the structural stability between the pressure-resistant test beam 504, the pressure-resistant test column 503, and the pressure-resistant test base plate 502, thereby ensuring the overall structural strength of the pressure detection bracket 5.

[0090] The pressure test push plate 501 is driven to move up and down by the third lifting mechanism installed on the pressure test bracket 5. The third lifting mechanism is: a vertically arranged third lifting guide rail 507 is installed on each of the two pressure test columns 503, and a third lifting slider 508 is installed on both sides of the pressure test push plate 501 for use with the third lifting guide rail 507. A third lifting cylinder 509 is also installed on the pressure test beam 504. The piston rod of the third lifting cylinder 509 is connected to the pressure test push plate 501, and drives the pressure test push plate 501 to move up and down along the third lifting guide rail 507.

[0091] There are several pressure test components, which are distributed in parallel along the second direction on the pressure detection push plate 502. The pressure test components include a first pressure contact 510, a second lever 511, a third contact mounting plate 518, a second spring pressure head 521, and a pressure measuring head 514.

[0092] There are two first pressure-resistant contacts 510, which are distributed in parallel on the pressure-resistant detection push plate 502. The pressure-resistant detection push plate 502 is also provided with a through hole for accommodating the installation and movement of the first pressure-resistant contacts 510. The first pressure-resistant contacts 510 are driven by the second lifting mechanism to move up and down.

[0093] like Figure 20 、 Figure 21 、 Figure 22 As shown, the second lifting mechanism is as follows: two first pressure-resistant contacts 510 are respectively installed on the pressure-resistant detection push plate 502 through a contact pressure rod 511, and a through hole is opened on the contact pressure rod 511 to accommodate the first pressure-resistant contact 510 to pass through. A limit ring 512 is also connected to the middle position of the first pressure-resistant contact 510. The size of the limit ring 512 is larger than the size of the through hole on the contact pressure rod 511. The top end of the first pressure-resistant contact 510 passes through the through hole on the first pressure-resistant contact 510 and then extends out of the first pressure-resistant contact 510. The upper end surface of the first voltage-resistant contact 510 is fixed by a nut, and the top end of the first voltage-resistant contact 510 is locked by a nut. The top end of the first voltage-resistant contact 510 is provided with an external thread structure that cooperates with the nut. The limiting ring 512 cooperates with the nut to realize the connection and fixation between the first voltage-resistant contact 510 and the contact pressure rod 511. With this structure, the first voltage-resistant contact 510 is detachably connected, which facilitates the installation of the first voltage-resistant contact 510 and also facilitates the subsequent disassembly, replacement and maintenance of the first voltage-resistant contact 510.

[0094] The pressure detection push plate 502 is provided with through holes for installing two contact pressure rods 511. The two contact pressure rods 511 are movably installed in the through holes on the pressure detection push plate through a mounting rod 513. The contact pressure rods 511 and the mounting rod 513 are movably connected. A through hole for the mounting rod 513 to pass horizontally is provided on the contact pressure rod 511. The contact pressure rod 511 is directly mounted on the mounting rod 513, and the contact pressure rod 511 can rotate at any angle along the mounting rod 513. A spacer sleeve 514 is also mounted on the outer wall of the mounting rod 513 and is located between the two contact pressure rods 511. The spacer sleeve 514 is fixedly connected to the mounting rod 513. The two contact pressure rods 511 are separated by the spacer sleeve 514 to avoid interference caused by the two contact pressure rods 511 touching each other during subsequent actions, thereby ensuring the stable up and down movement of the first pressure-resistant contact 510. The two sides of the mounting rod 513 are directly fixed on the pressure-resistant detection push plate 502.

[0095] One side of the contact pressure rod 511 is connected to the first pressure-resistant contact 510. The other side of the contact pressure rod 511 is driven by a second lifting cylinder 514 installed on the pressure-resistant test push plate 502 to swing up and down, thereby driving the first pressure-resistant contact 510 to move up and down. The second lifting cylinder 514 is a pneumatic cylinder. The design of the second lifting mechanism, through the mutual cooperation of components such as the contact pressure rod 511, the mounting rod 513, and the second lifting cylinder 514, uses a swinging method to achieve the up and down movement of the first pressure-resistant contact 510. During the pressure test, under the requirement of applying the same force to the first pressure-resistant contact 510, compared with directly using a drive cylinder to drive the first pressure-resistant contact 510, the use of the principle of a lever to apply force greatly reduces the force required by the second lifting cylinder 514. In other words, the requirements for the second lifting cylinder 514 are reduced, and the corresponding testing costs are also reduced.

[0096] A protruding connecting shaft 515 is connected to the side of the contact pressure rod 511 near the second lifting cylinder 514. A cylinder push block 516 is also connected to the bottom end of the piston rod of the second lifting cylinder 514. The cylinder push block 516 has a waist-shaped mounting hole 517 that allows the connecting shaft 515 to extend and move. The waist-shaped mounting hole 517 is designed to allow the connecting shaft 515 to move within a certain range within the mounting hole 517, facilitating the second lifting cylinder 514 to drive the contact pressure rod 511. The connecting shaft 515 cooperates with the cylinder push block 516 to achieve the drive between the second lifting cylinder 514 and the contact pressure rod 511, eliminating the need for connecting components such as pins to achieve an articulated connection, thereby facilitating installation and subsequent maintenance.

[0097] A through hole is provided on the pressure resistance detection push plate 502 for the second lever 511 to pass through and move. The second lever 511 is driven by the second lever mechanism to swing back and forth. The matching structure between the second lever 511 and the second lever mechanism is the same as the matching structure between the first lever 407 and the first lever mechanism, and will not be described in detail in this embodiment.

[0098] The third contact mounting plate 518 is installed at the end of the voltage-resistant detection push plate 502 close to the characteristic test unit, and the third contact mounting plate 518 is pushed up and down by a lifting cylinder 519 installed on the voltage-resistant detection push plate 502. The lifting cylinder 519 is fixed on the voltage-resistant detection push plate 502, and a conductive connector male contact 520 is installed on the third contact mounting plate 518, which corresponds one-to-one with the conductive connector female contact 207.

[0099] There are two second spring pressing heads 521 , which are respectively arranged on both sides of the bottom end surface of the pressure resistance detection push plate 502 . The structure of the second spring pressing head 521 is the same as that of the first spring pressing head 418 , and will not be described in detail in this embodiment.

[0100] The pressure-resistant measuring head includes a pressure-resistant lifting cylinder 522, a second pressure-resistant contact 523, and a contact connector 524. The second pressure-resistant contact 523 is connected to the contact connector 524. A through hole is provided on the contact connector 524 for accommodating the installation of the second pressure-resistant contact 523. The contact connector 524 is driven by the pressure-resistant lifting cylinder 522 to move up and down, thereby driving the second pressure-resistant contact 523 to move up and down. The pressure-resistant lifting cylinder 522 is a pneumatic cylinder. The pressure-resistant lifting cylinder 522 is installed on the pressure-resistant detection push plate 502 through a cylinder mounting seat 525. A through hole is also provided on the pressure-resistant detection push plate 502 for accommodating the contact connector 524 and the second pressure-resistant contact 523 to move up and down.

[0101] A protective cover covering the loading and unloading area, characteristic test area, resistance test area and withstand voltage test area is also installed on the test base 1. The protective cover includes a protective bracket 102, a side panel 106, a cover panel 107 and a door stopper 108. The bottom end of the protective bracket 102 is fixed to the test platform 101. The protective bracket 102 is a hollow rectangular structure formed by connecting a number of profiles. Side panels 106 and door stoppers 108 are installed on the four sides of the protective bracket 102, and a cover panel 107 is installed on the top of the protective bracket 102. The side panels 106, door stoppers 108 and cover panels 107 cooperate to form a closed cavity that covers the characteristic test unit, the resistance test unit and the withstand voltage test unit. Space is reserved on the protective cover for manual loading and unloading in the loading and unloading area. The design of the protective cover on the test base 1 is used to protect the characteristic test unit, resistance test unit, voltage test unit, and conveying unit, to avoid external interference in the test process and ensure the smooth progress of the test; and the design of the door baffle 108 is to facilitate personnel to open it and observe the internal test status.

[0102] A partition door is installed between the loading and unloading area and the characteristic testing area. The partition door includes a fixed door panel 104 and a movable door panel 103, which are arranged vertically. The movable door panel 103 is driven up and down by a pneumatic cylinder 105 mounted on the fixed door panel 104, thereby separating or connecting the loading and unloading area and the characteristic testing area. The opening and closing cylinder 105 is a pneumatic cylinder. The partition door is designed to cooperate with the protective cover. The combination of the fixed door panel 104 and the movable door panel 105 allows manual loading and unloading of bypass switch products in the loading and unloading area, while also separating the bypass switch from the loading and unloading area during testing, thus preventing external interference with the testing process.

[0103] The cavity inside the test base 1 is also equipped with a gas storage tank for supplying gas to all cylinders, an industrial computer connected to each unit for unified control, a characteristic meter connected to the characteristic test unit, and a characteristic meter power supply for powering the characteristic meter. An insulation meter 111, a resistance meter 112, and a laser control box 113 connected to the resistance test unit are also installed on the protective cover.

[0104] The test rack is also equipped with a display screen 110, mounted on a protective cover and located above the insulation tester 111. Together with the industrial computer, the display screen 110 displays test status, test results, and other data. This display screen 110 allows testers to visually verify the performance of the bypass switch under test and ensure compliance with requirements. It also provides a foundation for subsequent traceability of all tested bypass switches.

[0105] A marking unit is also installed on the test rack 1. The marking unit is located between the loading and unloading area and the characteristic test area. Figure 25 、 Figure 26 As shown, the marking unit includes a marking bracket 6 , a laser marking head 601 , a laser fixing plate 602 , a horizontal adjustment plate 603 , and a height adjustment plate 604 .

[0106] The marking bracket 6 is installed on the test platform 101. The marking bracket 6 includes a marking base 605 and a marking column 606. There is a pair of marking bases 605, which are distributed in parallel on the test platform 101 along the second direction, and the marking base 605 and the test platform 101 are fixed by bolts. There is a pair of marking columns 606, which are connected to the marking bases 605 one by one. A marking reinforcement plate 607 is also connected between the marking columns 606 and the marking base 605, thereby improving the structural strength of the marking bracket 6.

[0107] A first transition plate 608 is connected to each side of the height adjustment plate 604. The first transition plate 608 is a composite plate formed by a horizontal plate and a vertical plate connected in a "7" shape. The vertical plate of the first transition plate 608 is bolted to the marking column 606. The marking column 606 also has mounting holes 609 that allow bolts to pass through and allow for vertical movement. The mounting holes 609 are waist-shaped, and each marking column 606 has two mounting holes 609, distributed vertically. The vertical plate of the first transition plate 608 also has two through-holes distributed vertically for bolts to pass through. Two bolts are sequentially passed through the through-holes in the vertical plate of the first transition plate 608, then through the two mounting holes 609, and then tightened with nuts, thereby securing the height adjustment plate 604 to the marking bracket 6. The horizontal plate of the first transition plate 608 is designed to cooperate with the marking column 606 to limit the descending travel of the height adjustment plate 604.

[0108] The horizontal adjustment plate 603 is installed on the side of the height adjustment plate 604. The laser marking head 601 is installed on the horizontal adjustment plate 603 through the laser fixing plate 602. The laser fixing plate 602 is movably connected to the horizontal adjustment plate 603 and moves back and forth along the horizontal adjustment plate. Two second transition plates 610 distributed up and down are also connected to the side of the laser fixing plate 602. The second transition plate 610 is also a combination plate formed by connecting the horizontal plate and the vertical plate in a 7 shape. The horizontal plates of the second transition plate 610 are all connected to the laser fixing plate 602. The side ends of the fixed plate 602 are fixed, and guide grooves for accommodating the vertical plates of the second transition plate 610 to be embedded are provided on the upper and lower sides of the horizontal adjustment plate 603, and the guide grooves extend along the second direction. The second transition plate 610 moves back and forth along the guide grooves, thereby realizing the horizontal movement of the laser fixed plate 602 along the second transition plate 610. The laser fixed plate 602 is driven to move by a marking cylinder installed on the second transition plate 610, and the marking cylinder is fixed to the horizontal adjustment plate 603 through a cylinder mounting plate.

[0109] The marking unit is designed to mark the bypass switches passing through it through the laser marking head 601, so as to facilitate the subsequent classification of qualified and unqualified bypass switch products; and through the cooperation of the horizontal adjustment plate 603 and the height adjustment plate 604, the upper and lower heights of the laser marking head 601 can be adjusted and the horizontal movement of the laser marking head 601 can be facilitated, so that the laser marking head 601 can mark multiple bypass switch products.

[0110] Working principle: When testing the bypass switch product, first, a plurality of bypass switch products to be tested are manually placed on the first tooling plate 201 in the loading and unloading area, and positioned and fixed by the positioning protrusion 204. Then, the male connector on the bypass switch product is inserted into the female connector 205, and the bypass switch product is connected to the terminal block 205.

[0111] After the bypass switch product is placed, the first motor 213 works to drive the first screw 212 to rotate, and drives the second tooling plate 203 to move back and forth along the first direction. At the same time, the movable door panel 103 is opened in advance, so as to facilitate the entire tooling plate 2 to move from the loading and unloading area to the characteristic test area / resistance test area. After the tooling plate 2 moves to the characteristic detection area / resistance test area, the first motor 213 stops working, and after the tooling plate 2 enters the characteristic detection area / resistance test area, the movable door panel 103 moves downward and closes.

[0112] Characteristic test, the characteristic detection push plate 402 drops to the set position, the first spring pressure head 418 presses on both sides of the bypass switch product, and the conductive connector male contact 417 on the second contact mounting plate 416 contacts with each conductive connector female contact 207 one by one, realizing the connection between the conductive connector male contact 417 and the conductive connector female contact 207, and the first characteristic contact 420 presses on the bypass switch product. Then, the first push cylinder 435 drives the first lever 407 downward, so that the first lever 407 is inserted from the opening and closing port of the bypass switch product, and then the first lever mechanism drives the first lever 407 in. The first lever 407 is swung back and forth, thereby utilizing the first lever 407 to realize the continuous opening and closing operation of the bypass switch product for characteristic testing. After the characteristic test of the first bypass switch product is completed, the first push cylinder 435 drives the first lever 407 upward, and then the characteristic detection push plate 402 moves upward, and then the characteristic detection push plate 402 moves horizontally along the second direction, so that the first lever 407 moves to the top of the second bypass switch product, and then the characteristic detection push plate 402 moves downward to perform characteristic testing on the second bypass switch product. This is repeated until the characteristic testing of all bypass switch products on the tooling plate 2 is completed.

[0113] Resistance test, when the characteristic detection push plate 402 moves downward and the characteristic test is performed on the second bypass switch product, as the characteristic detection push plate 402 moves downward, the resistance contact 71 will press on the first bypass switch product, and the resistance tester 7 and the resistance contact 71 will cooperate to perform a resistance test on the first bypass switch product. This process is repeated to complete the resistance test of all bypass switch products on the tooling board. When performing a resistance test on the last bypass switch product on the tooling board 2, since all bypass switch products have completed the characteristic test, the characteristic detection push plate 402 needs to move one position in the second direction again to perform a resistance test on the last bypass switch product.

[0114] After all bypass switch products on the tooling board 2 have completed the characteristic and resistance tests, the characteristic detection push plate 402 moves upward, and then the first motor 213 works to drive the tooling board 2 from the characteristic test area / resistance test area to the voltage test area. After the work board 2 moves into place, the first motor 213 stops working.

[0115] Pressure test, the pressure detection push plate 502 moves downward to a specific position, the second spring pressure head 521 is pressed on both sides of the bypass switch product, and the third contact mounting plate 518 is pushed downward by the lifting cylinder 519, so that the male contact 520 of the conductive connector contacts the female contact 207 of the conductive connector one-to-one to achieve connection, and the second lifting cylinder 514 drives the first pressure-resistant contact 510 downward, so that the first pressure-resistant contact 510 is pressed on the bypass switch product, and the pressure-resistant lifting cylinder 522 drives the second pressure-resistant contact 523 downward, so that the second pressure-resistant contact 523 is pressed on the bypass switch product to perform a pressure test. When performing the pressure test, each second lever 511 respectively moves all the bypass switch products to perform opening and closing actions to test whether the bypass switch products can be smoothly opened and closed under this pressure environment.

[0116] After all bypass switch products on the tooling board 2 have completed the voltage test, the voltage detection push plate 502 moves upward, and then the first motor 213 works to drive the tooling board 2 to move from the voltage test area to the marking unit, and stops working after moving into place.

[0117] Marking: According to the information fed back by the industrial computer, the laser marking head 601 marks the first bypass switch product, and through the horizontal movement of the laser marking head 601, all the bypass switch products on the tooling plate 2 are marked.

[0118] After all the bypass switch products on the tooling plate 2 are marked, the first motor 213 is operated to drive the tooling plate 2 to move from the marking unit to the loading and unloading area, and stops working after moving into place. Before moving, the movable door panel 103 is opened in advance to facilitate the movement of the tooling plate 2 from the marking unit to the loading and unloading area. Finally, the bypass switch products that have been tested and marked are manually removed, and the next batch of bypass switch products are placed, and this process is repeated.
