Description

Technical Field

[0001] This invention relates to the technical field of testing the electrical performance of high-voltage contactors, and in particular to a testing device and method for testing the electrical performance of high-voltage contactors. Background Technology

[0002] The structure of a certain high-voltage contactor is as follows: Figures 1-3 As shown, the high-voltage contactor 1 includes a base 2 and a contactor body 3 fixed on the top surface of the base 2. A through hole 4 is provided at each of the four corners of the base 2. A notch is provided on the top surface of the contactor body 3. Conductive holes 5 are provided on the top surface of the contactor body 3 on both sides of the notch. Four auxiliary lines 6 are connected to the contactor body 3.

[0003] After a batch of high-voltage contactors 1 is produced in the workshop, the process requires that the electrical performance of each high-voltage contactor 1 be tested. This means that the high-voltage contactors must undergo insulation withstand voltage testing and a 10KV withstand voltage test. The method used by the workers in the workshop to test the electrical performance of a batch of high-voltage contactors 1 is as follows:

[0004] S1. Workers should wear insulating clothing and pants in advance, and wear insulating gloves on both hands;

[0005] S2. The worker takes out a high-voltage contactor 1 and places its base 2 flat on the test bench.

[0006] S3. Perform an insulation withstand voltage test on high-voltage contactor 1. The specific operating procedure is as follows:

[0007] S31. The worker places the 5KV withstand voltage tester 7 on the test bench.

[0008] S32. The worker inserts the two power connectors 8 of the 5KV withstand voltage tester 7 into the two conductive holes 5 of the high-voltage contactor 1, and then inserts the ends of the four auxiliary wires 6 on the high-voltage contactor 1 into the four wiring ports of the 5KV withstand voltage tester 7. At this time, the high-voltage contactor 1 and the 5KV withstand voltage tester 7 are electrically connected. Figure 4 As shown;

[0009] S33. Turn on the 5KV withstand voltage tester 7. The 5KV withstand voltage tester 7 applies a 5KV voltage to the high-voltage contactor 1. After the 5KV voltage has been applied for a period of time, if the leakage current displayed on the 5KV withstand voltage tester 7 is greater than 0.1 mA, the worker will determine that the high-voltage contactor 1 being tested is a defective product.

[0010] If the leakage current displayed on the 5KV withstand voltage tester 7 is less than or equal to 0.1 mA, the worker will determine that the high-voltage contactor 1 under test is a semi-qualified product 9, thus finally completing the insulation withstand voltage test of the high-voltage contactor 1.

[0011] S4. The worker conducts a 10KV withstand voltage test on the semi-conforming product 9. The specific operating steps are as follows:

[0012] S41. The worker places the 10KV withstand voltage tester 10 onto the test bench.

[0013] S42. The worker inserts the two power connectors 8 of the 10KV withstand voltage tester 10 into the two conductive holes 5 of the semi-qualified product 9, respectively. Then, the worker inserts the end of an auxiliary wire 6 on the semi-qualified product 9 into a wiring port of the 10KV withstand voltage tester 10. At this time, the semi-qualified product 9 is electrically connected to the 10KV withstand voltage tester 10. Figure 5 As shown;

[0014] S43. Turn on the 10KV withstand voltage tester 10. The 10KV withstand voltage tester 10 applies a 10KV voltage to the semi-qualified product 9. After the 10KV voltage has been applied for a period of time, if the leakage current displayed on the 10KV withstand voltage tester 10 is greater than 0.2 mA, the worker will determine that the semi-qualified product 9 being tested is a non-qualified product.

[0015] If the leakage current displayed on the 10KV withstand voltage tester 10 is less than or equal to 0.2 mA, the worker will determine that the semi-qualified product 9 being tested is qualified, thus completing the 10KV withstand voltage test on the semi-qualified product 9 and finally realizing the electrical performance test of the first high-voltage contactor 1.

[0016] S5. Workers can repeat steps S2 to S4 multiple times to perform electrical performance testing on a batch of high-voltage contactors 1 in the workshop.

[0017] However, although the methods used in the workshop can perform electrical performance testing on a batch of high-voltage contactors 1 within the workshop, the following technical shortcomings still emerge in actual operation:

[0018] I. In step S32, the worker needs to manually insert the two power connectors 8 of the 5KV withstand voltage tester into the two conductive holes 5 of the high voltage contactor 1, and also manually insert the ends of the four auxiliary wires 6 on the high voltage contactor 1 into the four wiring ports of the 5KV withstand voltage tester 7, so as to electrically connect the high voltage contactor 1 and the 5KV withstand voltage tester 7, so that the high voltage contactor 1 can be tested for insulation withstand voltage.

[0019] Similarly, in step S42, the worker needs to manually insert the two power connectors 8 of the 10KV withstand voltage tester into the two conductive holes 5 of the semi-qualified product 9, and also manually insert the end of an auxiliary wire 6 on the semi-qualified product 9 into a wiring port of the 10KV withstand voltage tester 10, so as to electrically connect the semi-qualified product 9 with the 10KV withstand voltage tester 10, and then perform the 10KV withstand voltage test on the semi-qualified product 9.

[0020] Therefore, a total of four manual wiring procedures are required, which undoubtedly increases the testing time for the electrical performance of the high-voltage contactor and thus reduces the testing efficiency.

[0021] II. Workers need to manually transfer the defective products detected to the repair workshop, and they also need to manually transfer the qualified products detected to the packaging workshop, which undoubtedly increases the workload of the workers.

[0022] Therefore, there is an urgent need for a testing device and method that can greatly improve the efficiency of testing the electrical performance of high-voltage contactors and greatly reduce the workload of workers. Summary of the Invention

[0023] The purpose of this invention is to overcome the shortcomings of the prior art and provide a testing device and method for testing the electrical performance of high-voltage contactors.

[0024] The objective of this invention is achieved through the following technical solution: a testing device for detecting the electrical performance of a high-voltage contactor, comprising a pad, a guide rail fixed on the pad and arranged horizontally, a 5KV withstand voltage test assembly for performing insulation withstand voltage tests on the high-voltage contactor, and a 10KV withstand voltage test assembly for performing 10KV withstand voltage tests on semi-conforming products.

[0025] A horizontal lead screw module is fixed on the pad between the two guide rails.

[0027] A first side-push cylinder is fixed on the top surface of the first support plate. A first side-push plate is fixed on the piston rod of the first side-push cylinder. Four first insert rods are fixed inside the first side-push plate along its length. The four first insert rods all penetrate the front and rear end faces of the first side-push plate. The front ends of the four first insert rods are connected to the four terminals of the 5KV withstand voltage tester via wires.

[0028] The 10KV withstand voltage test assembly includes a second column fixed on a pad and a second support plate fixed on the front end face of the front guide rail.

A second conductive rod penetrating the top and bottom surfaces of each of the two second insulating lifting blocks is fixed inside. The top ends of the two second conductive rods are connected to the two power supply terminals of the 10KV withstand voltage tester via wire P.

[0029] A second side-push cylinder is fixed on the top surface of the second support plate. A second side-push plate is fixed on the piston rod of the second side-push cylinder. A second insert rod is fixed inside the left end of the second side-push plate. The second insert rod passes through the front and rear end faces of the second side-push plate. The front end of the second insert rod is connected to a terminal of a 10KV withstand voltage tester via a wire p.

[0030] Support columns are fixed on the bottom surfaces of the left and right ends of the two guide rails, and the support columns are fixed on the pad.

[0031] The carrier includes a sliding plate, a positioning seat fixed to the top surface of the sliding plate, and a strip-shaped insulating seat. Two positioning pins are fixed to the top surface of the positioning seat in a diagonal arrangement. Four L-shaped grooves are opened on the top surface of the strip-shaped insulating seat at intervals. The long groove of the L-shaped groove extends forward through the front end face of the strip-shaped insulating seat. A plastic post is fixed to the bottom of the short groove of the L-shaped groove. An L-shaped conductive block is installed inside the L-shaped groove. The long part of the L-shaped conductive block extends forward through the L-shaped groove. A spring is fixed between the L-shaped conductive block and the rear side wall of the short groove of the L-shaped groove. Under the elastic force of the spring, the short part of the L-shaped conductive block presses against the plastic post.

[0032] A cover plate is fixed on the top surface of the strip-shaped insulating base, and four recessed grooves are opened in the cover plate. The four recessed grooves are respectively connected to the short grooves of the four L-shaped grooves.

[0033] The spacing between any two adjacent L-shaped slots in the strip insulating base of the carrier is equal.

[0034] The longitudinal width of the sliding plate of the carrier is equal to the distance between the limiting guide grooves of the two guide rails. The left and right ends of the sliding plate are provided with slots, and the horizontal distance between the two slots is equal to the horizontal distance between the two blocks on the moving plate.

[0035] The testing device also includes a feeding assembly, which is located on the right side of the two guide rails. The feeding assembly includes a longitudinal flat belt conveyor, a transverse flat belt conveyor, and a handling robotic arm, all mounted on the pad. The moving part of the handling robotic arm is equipped with a double-acting cylinder, and each of the two piston rods of the double-acting cylinder is connected to a clamping plate, which is positioned opposite to the front and back of the cylinder.

[0036] The detection device also includes a controller, which is electrically connected to a horizontal lead screw module, a first linear cylinder, a first side-push cylinder, a second linear cylinder, a second side-push cylinder, a handling robotic arm, and a double-acting cylinder.

[0037] A method for testing the electrical performance of a high-voltage contactor, comprising the following steps:

[0038] S1. Install the high-voltage contactor to be tested on the carrier. The specific operating steps are as follows:

[0039] S11. The worker takes out a high-voltage contactor to be tested, puts the two opposite through holes on the base of the high-voltage contactor onto the two positioning pins of the carrier, and supports the base on the top surface of the positioning seat of the carrier.

[0040] S12. The worker uses his thumb to press an L-shaped conductive block backward on the carrier. The L-shaped conductive block compresses the spring backward, and the short part of the L-shaped conductive block separates from the plastic column, forming a space between the short part of the L-shaped conductive block and the plastic column. The worker then passes the end of an auxiliary wire of the high-voltage contactor downward through the groove of the cover plate and inserts it into the space.

[0041] S13. The worker releases his thumb, and under the elastic restoring force of the compressed spring, the L-shaped conductive block moves forward along the L-shaped groove. The end of the auxiliary line is clamped and fixed between the short part of the L-shaped conductive block and the plastic column, thus fixing one auxiliary line of the high-voltage contactor to the carrier.

[0042] S14. The worker repeats step S13 three times to fix the other three auxiliary lines of the high-voltage contactor on the carrier, thus finally realizing the installation of the high-voltage contactor to be tested on the carrier.

[0043] S2. The worker places the two slots of the sliding plate of the carrier onto the two blocks of the moving plate. Since the longitudinal width of the sliding plate is equal to the distance between the limiting guide grooves of the two guide rails, and the horizontal distance between the two slots is equal to the horizontal distance between the two blocks of the moving plate, the carrier is installed on the moving plate. At this time, the sliding plate is restricted between the two blocks in the horizontal direction, and at the same time, the sliding plate is restricted between the limiting guide grooves of the two guide rails in the longitudinal direction.

[0044] S3. Perform an insulation withstand voltage test on the high-voltage contactor on the vehicle. The specific operating steps are as follows:

[0045] S31. The motor of the horizontal lead screw module is started, and the moving plate on the horizontal lead screw module moves to the right. The moving plate drives the carrier and the high-voltage contactor installed on the carrier to move to the right synchronously. When the motor runs for a set time, the controller controls the motor to shut down. At this time, the high-voltage contactor enters the test position of the 5KV withstand voltage test component. The two conductive holes of the high-voltage contactor are respectively located directly below the two first conductive rods of the 5KV withstand voltage test component. At the same time, the four L-shaped conductive blocks of the carrier are respectively opposite to the four first insert rods.

[0046] S32. The moving part of the first linear cylinder of the 5KV withstand voltage test assembly moves downward, which drives the first connecting frame to move downward. The first connecting frame drives the two first insulating lifting blocks to move downward synchronously. The first insulating lifting blocks drive the first conductive rods fixed inside them to move downward synchronously. The first conductive rods move towards the conductive holes of the high-voltage contactor. After the first linear cylinder has been running for a period of time, the lower ends of the two first conductive rods are respectively inserted into the two conductive holes of the high-voltage contactor.

[0047] S33. Control the piston rod of the first side push cylinder of the 5KV withstand voltage test assembly to move backward. The piston rod drives the first side push plate to move forward. The first side push plate drives the four first insert rods inside to move backward synchronously. When the piston rod of the first side push cylinder is fully extended, the rear ends of the four first insert rods contact the four L-shaped conductive blocks of the carrier respectively. At this time, the high voltage contactor is electrically connected to the 5KV withstand voltage tester.

[0048] S34. Turn on the 5KV withstand voltage tester. The 5KV withstand voltage tester applies 5KV voltage to the high-voltage contactor. After the 5KV voltage has been applied for a period of time, if the leakage current displayed on the 5KV withstand voltage tester is greater than 0.1 mA, the worker determines that the tested high-voltage contactor is a defective product. At this time, the method for the worker to transfer the defective product to the repair workshop is as follows:

[0049] S341. Control the moving part of the first linear cylinder of the 5KV withstand voltage test assembly to move upward, thereby resetting the two first conductive rods. Then control the piston rod of the first side push cylinder of the 5KV withstand voltage test assembly to retract, so as to reset the four first insert rods.

[0050] S342, control the motor of the horizontal lead screw module to start, the moving plate drives the carrier and the defective products on the carrier to move synchronously to the right. When the motor runs for a set time, the controller controls the motor to shut down. At this time, the defective products are in the unloading position of the handling robot arm.

[0051] S343. Control the movement of the handling robot arm so that its two clamps fit over the outside of the defective product; then control the two piston rods of the double-acting cylinder to retract, thereby driving the two clamps to hold the defective product.

[0052] S344. Control the operation of the handling robotic arm to move the defective product directly above the longitudinal flat belt conveyor;

[0053] S345, both piston rods of the control double-acting cylinder extend, and the two clamping plates move in opposite directions. At this time, the defective product falls onto the flat belt of the longitudinal flat belt conveyor, and the flat belt transports the defective product to the repair workshop.

[0054] If the leakage current displayed on the 5KV withstand voltage tester is less than or equal to 0.1 mA, the worker will determine that the high-voltage contactor being tested is a semi-qualified product.

[0055] S4. Perform a 10KV withstand voltage test on the semi-qualified products. The specific operating steps are as follows:

[0056] S41. The motor of the horizontal lead screw module is started, and the moving plate on the horizontal lead screw module moves to the right. The moving plate drives the carrier and the semi-qualified product installed on the carrier to move to the right synchronously. When the motor runs for a set time, the controller controls the motor to shut down. At this time, the semi-qualified product enters the test position of the 10KV withstand voltage test assembly. The two conductive holes of the semi-qualified product are respectively located directly below the two second conductive rods of the 10KV withstand voltage test assembly. At the same time, one of the L-shaped conductive blocks in the carrier is opposite to the second insertion rod.

[0057] S42. Control the movement of the second linear cylinder of the 10KV withstand voltage test assembly downward so that the lower ends of the two second conductive rods are respectively inserted into the two conductive holes of the semi-qualified product;

[0058] S43. Control the piston rod of the second side push cylinder of the 10KV withstand voltage test assembly to extend forward, and the rear end of the second insert rod contacts the L-shaped conductive block opposite it. At this time, the semi-qualified product is electrically connected to the 10KV withstand voltage tester.

[0059] S44. Turn on the 10KV withstand voltage tester. The 10KV withstand voltage tester applies 10KV voltage to the semi-qualified product. After the 10KV voltage has been applied for a period of time, if the leakage current displayed on the 10KV withstand voltage tester is greater than 0.2 mA, the worker will determine that the semi-qualified product being tested is a defective product. At this time, the worker repeats the operation of steps S341~S345 once, and the defective product can be transferred to the repair workshop.

[0060] If the leakage current displayed on the 10KV withstand voltage tester is less than or equal to 0.2 mA, the worker determines that the semi-qualified product is qualified. In this case, the worker transfers the qualified product to the packaging workshop in the following manner:

[0061] S441, control the movement of the second linear cylinder of the 10KV withstand voltage test assembly to move upward, thereby resetting the two second conductive rods, and then control the piston rod of the second side push cylinder of the 5KV withstand voltage test assembly to retract, so as to reset the second insertion rod;

[0062] S442: The motor of the horizontal lead screw module is started, and the moving plate drives the carrier and the qualified products on the carrier to move synchronously to the right. When the motor runs for a set time, the controller controls the motor to shut down. At this time, the qualified products are in the unloading position of the handling robot arm.

[0063] S443. Control the movement of the handling robot arm so that its two clamps fit over the qualified product; then control the two piston rods of the double-acting cylinder to retract, thereby driving the two clamps to hold the qualified product.

[0064] S444. Control the operation of the handling robotic arm to move qualified products directly above the transverse flat belt conveyor;

[0065] S445, both piston rods of the double-acting cylinder extend, and the two clamping plates move in opposite directions. At this time, the qualified product falls onto the horizontal belt of the transverse flat belt conveyor, which transports the qualified product to the packaging workshop, thus ultimately realizing the testing of the electrical performance of a high-voltage contactor.

[0066] The present invention has the following advantages: it greatly improves the efficiency of electrical performance testing of high voltage contactors and greatly reduces the workload of workers. Attached Figure Description

[0106] S1. Install the high-voltage contactor 1 to be tested on the carrier. The specific operating steps are as follows:

[0107] S11, The worker takes out a... Figures 1-3The high-voltage contactor 1 to be tested is shown. Two opposing through holes 4 on the base 2 of the high-voltage contactor 1 are respectively fitted onto... Figures 12-13 The two positioning pins 38 of the vehicle shown are used to support the base 2 on the top surface of the positioning seat 36 of the vehicle, as follows. Figure 18 As shown;

[0108] S12. The worker uses his thumb to press an L-shaped conductive block 41 backward on the carrier. The L-shaped conductive block 41 compresses the spring 42 backward. The short part of the L-shaped conductive block 41 separates from the plastic column 40, and a space is formed between the short part of the L-shaped conductive block 41 and the plastic column 40. The worker passes the end of an auxiliary wire 6 of the high-voltage contactor 1 downward through the groove 44 of the cover plate 43, and then inserts it into the space.

[0109] S13. The worker releases his thumb, and under the elastic restoring force of the compressed spring 42, the L-shaped conductive block 41 moves forward along the L-shaped groove 39. The end of the auxiliary line 6 is clamped and fixed between the short part of the L-shaped conductive block 41 and the plastic post 40, thereby fixing one auxiliary line 6 of the high-voltage contactor 1 to the carrier.

[0110] S14. The worker repeats step S13 three times to fix the other three auxiliary lines 6 of the high voltage contactor 1 on the carrier, thus finally realizing the installation of the high voltage contactor 1 to be tested on the carrier.

[0111] S2. The worker places the two slots 45 of the sliding plate 35 of the carrier onto the two blocks 15 on the moving plate 14. Since the longitudinal width of the sliding plate 35 is equal to the distance between the limiting guide grooves 16 of the two guide rails 12, and the horizontal distance between the two slots 45 is equal to the horizontal distance between the two blocks 15 on the moving plate 14, the carrier is thus installed onto the moving plate 14. Figures 19-20 As shown, at this time, the sliding plate 35 is restricted between the two locking blocks 15 in the horizontal direction, and at the same time, the sliding plate 35 is restricted between the limiting guide grooves 16 of the two guide rails 12 in the longitudinal direction.

[0112] S3. Perform an insulation withstand voltage test on the high-voltage contactor 1 on the vehicle. The specific operating steps are as follows:

[0113] S31. The motor of the horizontal lead screw module 13 is started, and the moving plate 14 on the horizontal lead screw module 13 moves to the right. The moving plate 14 drives the carrier and the high voltage contactor 1 installed on the carrier to move to the right synchronously. When the motor runs for a set time, the controller controls the motor to shut down. At this time, the high voltage contactor 1 enters the test position of the 5KV withstand voltage test assembly. The two conductive holes 5 of the high voltage contactor 1 are respectively located directly below the two first conductive rods 22 of the 5KV withstand voltage test assembly. At the same time, the four L-shaped conductive blocks 41 of the carrier are respectively opposite to the four first insert rods 25.

[0114] S32. The moving part of the first linear cylinder 19 of the 5KV withstand voltage test assembly moves downward, which drives the first connecting frame 20 to move downward. The first connecting frame 20 drives the two first insulating lifting blocks 21 to move downward synchronously. The first insulating lifting blocks 21 drive the first conductive rods 22 fixed inside them to move downward synchronously. The first conductive rods 22 move towards the conductive holes 5 of the high voltage contactor 1. After the first linear cylinder 19 has been running for a period of time, the lower ends of the two first conductive rods 22 are respectively inserted into the two conductive holes 5 of the high voltage contactor 1.

[0115] S33, the piston rod of the first side push cylinder 23 of the 5KV withstand voltage test assembly moves backward, the piston rod drives the first side push plate 24 to move forward, and the first side push plate 24 drives the four first insertion rods 25 inside it to move backward synchronously; when the piston rod of the first side push cylinder 23 is fully extended, the rear ends of the four first insertion rods 25 respectively contact the four L-shaped conductive blocks 41 of the carrier, at this time, the high voltage contactor 1 is electrically connected to the 5KV withstand voltage tester;

[0116] S34. Turn on the 5KV withstand voltage tester and apply 5KV voltage to the high-voltage contactor 1. After the 5KV voltage has been applied for a period of time, if the leakage current displayed on the 5KV withstand voltage tester is greater than 0.1 mA, the worker will determine that the tested high-voltage contactor 1 is a defective product. At this time, the worker will transfer the defective product to the repair workshop in the following way:

[0117] S341, control the moving part of the first linear cylinder 19 of the 5KV withstand voltage test assembly to move upward, thereby resetting the two first conductive rods 22, and then control the piston rod of the first side push cylinder 23 of the 5KV withstand voltage test assembly to retract, so as to reset the four first insertion rods 25.

[0118] S342, the motor of the horizontal lead screw module 13 is started, and the moving plate 14 drives the carrier and the defective products on the carrier to move to the right synchronously. When the motor runs for a set time, the controller controls the motor to shut down. At this time, the defective products are in the unloading position of the handling robot arm 48.

[0119] S343, control the operation of the handling robot arm 48 so that the two clamping plates 50 on it are placed on the outside of the defective product; then control the two piston rods of the double-acting cylinder 49 to retract, thereby driving the two clamping plates 50 to clamp the defective product.

[0120] S344, Control the operation of the handling robot arm 48 to move the defective product directly above the longitudinal flat belt conveyor 46;

[0121] S345, both piston rods of the double-acting cylinder 49 extend and the two clamping plates 50 move in opposite directions. At this time, the defective product falls onto the flat belt of the longitudinal flat belt conveyor 46, and the flat belt transports the defective product to the repair workshop.

[0122] If the leakage current displayed on the 5KV withstand voltage tester is less than or equal to 0.1 mA, the worker will determine that the high-voltage contactor 1 being tested is a semi-qualified product.

[0123] S4. Perform a 10KV withstand voltage test on the semi-qualified products. The specific operating steps are as follows:

[0124] S41, the motor of the horizontal lead screw module 13 is started, and the moving plate 14 on the horizontal lead screw module 13 moves to the right. The moving plate 14 drives the carrier and the semi-qualified product installed on the carrier to move to the right synchronously. When the motor runs for a set time, the controller controls the motor to shut down. At this time, the semi-qualified product enters the test position of the 10KV withstand voltage test assembly. The two conductive holes 5 of the semi-qualified product are respectively located directly below the two second conductive rods 31 of the 10KV withstand voltage test assembly. At the same time, one of the L-shaped conductive blocks 41 in the carrier is opposite to the second insertion rod 34.

[0125] S42. Control the movement of the second linear cylinder 28 of the 10KV withstand voltage test assembly downward so that the lower ends of the two second conductive rods 31 are respectively inserted into the two conductive holes 5 of the semi-qualified product.

[0126] S43, the piston rod of the second side push cylinder 32 of the 10KV withstand voltage test assembly extends forward, and the rear end of the second insert rod 34 contacts the L-shaped conductive block 41 opposite to it. At this time, the semi-qualified product is electrically connected to the 10KV withstand voltage tester.

[0127] S44. Turn on the 10KV withstand voltage tester. The 10KV withstand voltage tester applies 10KV voltage to the semi-qualified product. After the 10KV voltage has been applied for a period of time, if the leakage current displayed on the 10KV withstand voltage tester is greater than 0.2 mA, the worker will determine that the semi-qualified product being tested is a defective product. At this time, the worker repeats the operation of steps S341~S345 once, and the defective product can be transferred to the repair workshop.

[0128] If the leakage current displayed on the 10KV withstand voltage tester is less than or equal to 0.2 mA, the worker determines that the semi-qualified product is qualified. In this case, the worker transfers the qualified product to the packaging workshop in the following manner:

[0129] S441, control the movement of the second linear cylinder 28 of the 10KV withstand voltage test assembly to move upward, thereby resetting the two second conductive rods 31, and then control the piston rod of the second side push cylinder 32 of the 5KV withstand voltage test assembly to retract, so as to reset the second insertion rod 34.

[0130] S442, the motor of the horizontal lead screw module 13 is started, and the moving plate 14 drives the carrier and the qualified products on the carrier to move to the right synchronously. When the motor runs for a set time, the controller controls the motor to shut down. At this time, the qualified products are in the unloading position of the handling robot arm 48.

[0131] S443, control the operation of the handling robot arm 48 so that the two clamping plates 50 on it are placed on the outside of the qualified product; then control the two piston rods of the double-acting cylinder 49 to retract, thereby driving the two clamping plates 50 to clamp the qualified product.

[0132] S444: Control the operation of the handling robot arm 48 to move the qualified product directly above the transverse flat belt conveyor 47;

[0133] S445, both piston rods of the double-acting cylinder 49 extend, and the two clamping plates 50 move in opposite directions. At this time, the qualified product falls onto the flat belt of the transverse flat belt conveyor 47, which transports the qualified product to the packaging workshop, thus ultimately realizing the testing of the electrical performance of a high-voltage contactor 1.

[0134] In step S1, the four auxiliary wires 6 of the high-voltage contactor 1 are fixed in the strip insulating base 37 by a carrier. Then, in step S3, by controlling the start of the first linear cylinder 19 and the first side-push cylinder 23 of the 5KV withstand voltage test assembly, the high-voltage contactor 1 is electrically connected to the 5KV withstand voltage tester, and the high-voltage contactor 1 is subjected to an insulation withstand voltage test. Then, in step S4, by controlling the start of the second linear cylinder 28 and the second side-push cylinder 32 of the 10KV withstand voltage test assembly, the semi-qualified product is electrically connected to the 10KV withstand voltage tester, and the semi-qualified product is subjected to a 10KV withstand voltage test.

[0135] Therefore, it can be seen that after the four auxiliary lines 6 of the high-voltage contactor 1 are fixed by the carrier, this testing device can automatically and quickly complete the electrical performance test of the high-voltage contactor 1 through the cooperation of the horizontal lead screw module 13, the 5KV withstand voltage test component, and the 10KV withstand voltage test component. Compared with other methods, this device can quickly and automatically complete the electrical performance test of the high-voltage contactor 1. Figures 4-5The testing method shown eliminates the need for four manual wiring steps to test the electrical performance of the high-voltage contactor 1, enabling the testing to be completed in a short time and thus greatly improving the testing efficiency.

[0136] Furthermore, as can be seen from steps S341~S345 and S441~S445, this testing device can automatically transfer non-conforming products to the horizontal belt of the longitudinal flat belt conveyor 46 via the handling robotic arm 48, and then the flat belt transports the non-conforming products to the repair workshop, or automatically transfer qualified products to the horizontal flat belt conveyor 47, and then the flat belt transports the qualified products to the packaging workshop.

[0137] Therefore, this testing device also realizes automatic sorting of defective or qualified products, eliminating the need for workers to manually transfer the detected defective products to the repair workshop, and eliminating the need for workers to manually transfer the detected qualified products to the packaging workshop, thus greatly reducing the workload of workers.
