Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and in particular to a testing device. Background Technology

[0002] To test the over-rated current protection tripping performance of a circuit breaker, it is usually necessary to inject current into the testing circuit using a DC power supply. The over-rated current protection tripping performance of the circuit breaker is confirmed by the magnitude of the current and the time. If the over-rated current protection tripping performance is poor, it needs to be repaired or replaced in time.

[0003] In the existing technology, the overcurrent protection tripping performance test of circuit breakers is rarely carried out using automatic testing equipment. The two connecting components of the automatic testing equipment correspond to the incoming and outgoing terminals of the circuit breaker, respectively. However, the lack of positioning of the circuit breaker affects the accuracy of the test, and the position and spacing of the two connecting components cannot be adjusted, resulting in poor applicability.

[0004] Therefore, there is an urgent need to provide a testing device to achieve automated testing, which can locate the circuit breaker during testing, and the position and spacing of the two connecting components can be adjusted to improve the applicability of the circuit breaker.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0061] like Figures 1 to 7 As shown, this embodiment provides a testing device for testing the over-rated current protection tripping performance of a circuit breaker 100. The circuit breaker 100 includes an incoming terminal 101 and an outgoing terminal 102. The testing device includes a testing module 10, which includes a positioning mechanism 13 and a testing mechanism 15. The positioning mechanism 13 includes a positioning base plate 131, a positioning top plate 133, and a positioning end plate 132 connected between the positioning base plate 131 and the positioning top plate 133. The positioning base plate 131 and the positioning top plate 133 are aligned along a first direction. The circuit breaker 100 is embedded in the area formed by the positioning base plate 131, the positioning end plate 132, and the positioning top plate 133. The detection mechanism 15 includes two connecting components 151 located on both sides of the positioning mechanism 13 along the second direction and arranged opposite to each other. The connecting components 151 can be raised and lowered along the first direction. The two connecting components 151 can move closer to each other or further away from each other along the second direction. One connecting component 151 is used to connect the inlet terminal 101, and the other connecting component 151 is used to connect the outlet terminal 102.

[0062] By embedding the circuit breaker 100 within the area enclosed by the positioning base plate 131, positioning end plate 132, and positioning top plate 133, the positioning base plate 131 and positioning top plate 133 clamp the circuit breaker 100 along the first direction, and the positioning end plate 132 positions the circuit breaker 100 from the side. The two connecting components 151 of the detection mechanism 15 are located on both sides of the positioning mechanism 13. When the side of the circuit breaker 100 is in contact with the positioning end plate 132, the position of the connecting component 151 matches the position of the circuit breaker 100. The connecting component 151 can move up and down along the first direction to match the position of the circuit breaker 100 in the first direction. The two connecting components 151 can move closer or further apart along the second direction to adjust the spacing and improve applicability.

[0063] In this embodiment, the first direction is the X direction, the second direction is the Z direction, and the third direction is the Y direction; the positioning base plate 131, the positioning end plate 132, and the positioning top plate 133 are all flat; the positioning base plate 131 and the positioning top plate 133 are spaced apart along the X direction and both extend along the Y direction to clamp the circuit breaker 100; the positioning end plate 132 extends along the X direction and its two ends are respectively connected to the positioning top plate 133 and the positioning base plate 131 to fit the side of the circuit breaker 100.

[0064] Furthermore, the testing equipment also includes an operation module 20, which includes a rotating base 24, a material gripping mechanism 25, and a screw tightening mechanism 26. The material gripping mechanism 25 and the screw tightening mechanism 26 are both connected to the rotating base 24. The rotation of the rotating base 24 can drive the material gripping mechanism 25 and the screw tightening mechanism 26 to rotate synchronously, so as to change the setting angle of the material gripping mechanism 25 and the screw tightening mechanism 26. The material gripping mechanism 25 is used to pick up and put down the circuit breaker 100, and the screw tightening mechanism 26 is used to tighten the wiring screws to the circuit breaker 100.

[0065] By setting up the detection module 10 and the operation module 20, the material gripping mechanism 25 of the operation module 20 grips the circuit breaker 100 and places it on the positioning mechanism 13 to limit the position of the circuit breaker 100, ensuring the accurate positioning of the circuit breaker 100. The rotating seat 24 is used to rotate and change the setting angle of the material gripping mechanism 25 and the screw tightening mechanism 26. The material gripping mechanism 25 grips the circuit breaker 100 and places it on the positioning mechanism 13, and then the screw tightening mechanism 26 tightens the wiring screws. Tighten the screws on the circuit breaker 100 to ensure that the metal plates of the circuit breaker 100 are at a uniform and flush angle. After tightening, adjust the position of the two connecting components 151 in the X direction and the spacing in the Z direction in the detection module 10 so that the two connecting components 151 are connected to the inlet terminal 101 and outlet terminal 102 on both sides of the circuit breaker 100, respectively, to facilitate subsequent conduction testing. Then rotate the rotating base 24 to switch the screw tightening mechanism 26 to the material gripping mechanism 25. The material gripping mechanism 25 takes the tested circuit breaker 100 away from the positioning mechanism 13.

[0066] In existing tests of the over-rated current protection tripping performance of circuit breakers, inconsistent tightening of the wiring screws on the circuit breaker leads to varying angles of the metal contacts, causing poor contact, prolonged energization, temperature rise, and frequent premature tripping. The testing equipment provided in this embodiment enables automated assembly and testing of the circuit breaker 100, offering higher efficiency compared to manual operation. Furthermore, an added screw tightening mechanism 26 ensures that the metal contacts of the circuit breaker 100 maintain a uniform and aligned angle during testing, preventing poor contact and guaranteeing the stability of the testing process.

[0067] Specifically, the circuit breaker 100 is a non-transparent cube with 8 electrode contact points, each corresponding to 8 wiring screws. The inlet terminal 101 and the outlet terminal 102 are located on both sides of the circuit breaker 100.

[0068] In this embodiment, the operation module 20 includes a robotic arm and a conveyor line 21. The conveyor line 21 extends along the Y direction. The robotic arm is mounted on the conveyor line 21 and can move along the conveyor line 21. The material gripping mechanism 25 and the screw tightening mechanism 26 are mounted on the robotic arm via a rotating base 24. The detection module 10 also includes a support frame 11 and a base 12 mounted on the support frame 11. The positioning mechanism 13 and the detection mechanism 15 are both mounted on the base 12. The positioning mechanism 13 is provided with multiple circuit breakers 100 for energizing and calibrating multiple circuit breakers 100. The detection mechanism 15 is configured in a one-to-one correspondence with the positioning mechanism 13. The robotic arm can use the gripping mechanism 25 to grab the circuit breaker 100 and move it along the conveyor line 21 to a position near the support frame 11 so that the circuit breaker 100 can be placed on the positioning mechanism 13. Similarly, after the inspection is completed, the robotic arm can use the gripping mechanism 25 to remove the circuit breaker 100 from the positioning mechanism 13 and move it along the conveyor line 21 to transport the circuit breaker 100 to the unloading line.

[0069] See Figure 2 The robotic arm includes a robotic arm 22 and an adapter 23. A rotating base 24 is rotatably mounted on the robotic arm 22 via the adapter 23. In this embodiment, the rotating base 24 is a hollow quadrangular prism. The adapter 23, the material gripping mechanism 25, and the screw tightening mechanism 26 are separately disposed on the three outer surfaces of the rotating base 24.

[0070] Optionally, both the material gripping mechanism 25 and the screw tightening mechanism 26 are detachably connected to the rotating base 24. The material gripping mechanism 25 and the screw tightening mechanism 26 can be fixed to the rotating base 24 with bolts. By providing the detachable material gripping mechanism 25 and the screw tightening mechanism 26, disassembly and maintenance are facilitated.

[0071] When the material gripping mechanism 25 is above the screw tightening mechanism 26, the material gripping mechanism 25 of the operating module 20 can grip a circuit breaker 100. After placing the circuit breaker 100 on the positioning mechanism 13, the robot arm adapter 23 is controlled to rotate, and the rotating seat 24 is driven to rotate at a certain angle, so that the material gripping mechanism 25 switches to the screw tightening mechanism 26, so that the screw tightening mechanism 26 is above the material gripping mechanism 25, and the screw tightening mechanism 26 tightens the wiring screw to the circuit breaker 100.

[0072] See Figures 5 to 9 Optionally, a positioning strip 1311 protrudes from the positioning base plate 131. The positioning strip 1311 extends along the Y direction and is used to slide into the groove 103 of the circuit breaker 100. The Y, X, and Z directions intersect at a point. By providing the positioning strip 1311 on the positioning base plate 131, and having the positioning strip 1311 engage with the groove 103 of the circuit breaker 100, the position of the circuit breaker 100 can be further restricted. In this embodiment, the X, Z, and Y directions are perpendicular to each other; the positioning strip 1311 is elongated, its width matches the width of the groove 103, and its length is greater than the length of the groove 103.

[0073] Optionally, the end of the positioning strip 1311 away from the positioning end plate 132 is provided with a guide slope. By providing a guide slope on the positioning strip 1311, it is easy to align the groove 103 of the circuit breaker 100 with the positioning strip 1311 and smoothly place the circuit breaker 100 on the positioning base plate 131.

[0074] In this embodiment, the positioning base plate 131, the positioning end plate 132, and the positioning top plate 133 are fixed together by bolts; the positioning end plate 132 is perpendicular to the positioning base plate 131 and the positioning top plate 133; the positioning end plate 132 is U-shaped, and two positioning top plates 133 are spaced apart along the Z direction; the positioning mechanism 13 also includes a second column 134, which extends along the X direction and has two columns spaced apart side by side along the Y direction. The positioning base plate 131 is mounted on the base 12 via the second columns 134; the second columns 134 can be fixed to the base 12 by bolts, and the positioning base plate 131 can be fixed to the second columns 134 by bolts.

[0075] When the circuit breaker 100 is placed on the positioning mechanism 13, the positioning base plate 131 and the positioning top plate 133 clamp the circuit breaker 100 along the X direction. The groove 103 of the circuit breaker 100 cooperates with the positioning strip 1311, which can prevent the circuit breaker 100 from falling off the positioning mechanism 13. The robot arm uses the material gripping mechanism 25 to grip the circuit breaker 100 and drive the circuit breaker 100 to slide along the Y direction on the positioning strip 1311. When the side of the circuit breaker 100 abuts against the positioning end plate 132, the placement of the circuit breaker 100 is completed. At this time, the position of the circuit breaker 100 in the Y direction is exactly matched with the position of the connecting component 151 of the detection mechanism 15 in the Y direction.

[0076] Optionally, the positioning mechanism 13 further includes a first elastic element 1333. A sliding block 1331 is slidably embedded on the positioning top plate 133 along the X direction. The first elastic element 1333 extends along the X direction and its two ends abut against the sliding block 1331 and the positioning top plate 133, respectively. By setting the sliding block 1331 and the first elastic element 1333, when the circuit breaker 100 is placed on the positioning base plate 131, as the circuit breaker 100 gradually moves, the circuit breaker 100 presses against the first elastic element 1333 and the sliding block 1331. Utilizing the elastic force of the first elastic element 1333, the sliding block 1331 can press the circuit breaker 100 against the positioning base plate 131, which helps to prevent the position of the circuit breaker 100 from shifting during the testing process.

[0077] In this embodiment, the positioning top plate 133 is also provided with a positioning block 1332, which is fixed above the positioning top plate 133. The sliding block 1331 overlaps and slides within the positioning top plate 133. The two ends of the first elastic member 1333 abut against the positioning block 1332 and the sliding block 1331 respectively. Each positioning top plate 133 is provided with two sliding blocks 1331 spaced apart along the Y direction, and correspondingly provided with two positioning blocks 1332 and four first elastic members 1333. The first elastic member 1333 can be a spring.

[0078] Furthermore, the detection module 10 also includes two sets of first guide rails 14 extending along the Z direction. The positioning mechanism 13 and the first guide rails 14 are both disposed on the base 12. The first guide rails 14 are located on both sides of the positioning mechanism 13. The connecting components 151 of the detection mechanism 15 are slidably disposed on the base 12 via the first guide rails 14. By setting the first guide rails 14 on the base 12, the two connecting components 151 of the detection mechanism 15 can move closer or further apart along the Z direction, thereby adjusting the interval between the two connecting components 151 to complete the crimping detection action and the release action. That is, when the two connecting components 151 move closer to each other and are respectively connected to the input terminal 101 and the output terminal 102 of the circuit breaker 100, the circuit breaker 100 maintains good contact and injects current for detection; after the detection is completed, the two connecting components 151 move further apart and are separated from the input terminal 101 and the output terminal 102 respectively.

[0079] Optionally, the base 12 includes a base plate 121 and a positioning block 122. The positioning block 122 is detachably mounted on the base plate 121, and the first guide rail 14 is mounted on the positioning block 122. By providing a detachable base plate 121 and positioning block 122, the position of the positioning block 122 and the length of the first guide rail 14 can be adjusted according to actual conditions. In this embodiment, the positioning block 122 is fixed to the base plate 121 by bolts.

[0080] Optionally, two sets of first guide rails 14 are provided, each set including two first guide rails 14, and the two first guide rails 14 in each set are arranged side by side with intervals along the Y direction. Correspondingly, four positioning blocks 122 are provided, and each positioning block 122 has one first guide rail 14. Each connecting component 151 is slidably mounted on the base 12 via a set of first guide rails 14. By arranging two first guide rails 14 side by side along the Y direction, the stability of the movement of the connecting component 151 is ensured.

[0081] To ensure synchronous operation of the two connecting components 151, the detection mechanism 15 further includes a translation drive 157, a first transmission structure 158, and a first rack 159. The first transmission structure 158 is rotatably mounted on the positioning base plate 131. Each connecting component 151 is connected to a first rack 159, and both first racks 159 mesh with the gears of the first transmission structure 158. The translation drive 157 is connected to one of the connecting components 151, and drives the two connecting components 151 closer to or further apart through the first transmission structure 158 and the two first racks 159. By utilizing the gear and rack mechanism, driving one connecting component 151 with the translation drive 157 will cause the other connecting component 151 to move synchronously, eliminating the need for separate control of the two connecting components 151.

[0082] In this embodiment, the translation drive 157 is a cylinder; a positioning strip 1311 is provided above the positioning base plate 131, and the first transmission structure 158 is located below the positioning base plate 131; the detection module 10 also includes a support plate 153, two of which are provided, each of which is slidably connected to a set of first guide rails 14; each connecting component 151 is provided on the support plate 153, and each support plate 153 is slidably provided on the positioning block 122 of the base 12 via a set of first guide rails 14. When the support plate 153 moves along the first guide rail 14, it drives the connecting component 151 to move accordingly; the translation drive 157 is connected to a support plate 153 via a floating joint, and the auxiliary block is detachably provided on the support plate 153 via bolts. The auxiliary block is provided with a first rack 159, and the auxiliary block is elongated and extends along the Z direction; the first racks 159 of the two connecting components 151 are respectively located on both sides of the gear of the first transmission structure 158.

[0083] To adjust the position of the connecting component 151 in the X direction, the detection module 10 further includes a first column 154, a lifting drive component 156, and a second guide rail 155 extending along the X direction. The first column 154 is provided in two sets, with each set including two components. Each support plate 153 is provided with a set of first columns 154. Each first column 154 is provided with a second guide rail 155. Each connecting component 151 is slidably connected to the two first columns 154 in the same set via the second guide rail 155. There are two lifting drive components 156. Each support plate 153 is provided with one lifting drive component 156. Each lifting drive component 156 is located between the two first columns 154 in the same set and is used to drive a connecting component 151 to move along the second guide rail 155. By adding a support plate 153 to the first guide rail 14, each connecting component 151 is individually set on a support plate 153, and the two connecting components 151 can move closer or further apart from each other in the Z direction; by setting a set of first columns 154 on each support plate 153, the two connecting components 151 can be slidably set on the two first columns 154 in the same group through the second guide rail 155, and the two connecting components 151 can be raised and lowered individually in the X direction. The setting height of the connecting component 151 relative to the base 12 is adjustable to accommodate circuit breakers 100 of different sizes.

[0084] In this embodiment, the first column 154 extends along the X direction. There are two sets of first columns 154, each set including two first columns 154 arranged side by side and spaced apart along the Y direction. Each connecting component 151 is slidably mounted on the two first columns 154 in the same set via the second guide rail 155 on both sides. There are two lifting drive components 156. The two sets of first columns 154 are respectively located on the top of the two support plates 153, and the two lifting drive components 156 are respectively located on the bottom of the two support plates 153. When the support plate 153 moves along the first guide rail 14, the first column 154 and the lifting drive component 156 also move relative to the base 12. The lifting drive component 156 is a cylinder. The two lifting drive components 156 pass through the corresponding support plates 153 through floating joints and are connected to the bottom of the two connecting components 151. The lifting drive component 156 is used to drive the connecting component 151 to move up and down along the X direction.

[0085] Specifically, the connecting assembly 151 includes a pressure rod 1511 and a fixing block 1512. The fixing block 1512 is slidably disposed on the second guide rail 155 and connected to the lifting drive component 156. The pressure rod 1511 is disposed on the fixing block 1512 for connecting the inlet end 101 or the outlet end 102. Because the pressure rod 1511 is disposed on the fixing block 1512, the fixing block 1512 can be slidably disposed on the first column 154 via the second guide rail 155. When the fixing block 1512 moves, it drives the pressure rod 1511 to move along the X direction.

[0086] In this embodiment, the fixing block 1512 is disposed on the support plate 153, and the two ends of the fixing block 1512 are respectively slidably disposed on the two first columns 154 in the same group via the second guide rail 155.

[0087] Optionally, the connecting assembly 151 further includes a second elastic element 1513. The first end of the pressure rod 1511 slides through the fixing block 1512 in the X direction, and the second end of the pressure rod 1511 extends in the Z direction to connect the inlet terminal 101 or the outlet terminal 102. One end of the second elastic element 1513 abuts against the fixing block 1512, and the other end abuts against the second end of the pressure rod 1511. By providing a pressure rod 1511 that slides through the fixing block 1512 and providing a second elastic element 1513 between the fixing block 1512 and the pressure rod 1511, the elastic force of the second elastic element 1513 allows the pressure rod 1511 to elastically contact the inlet terminal 101 or the outlet terminal 102 of the circuit breaker 100, ensuring good contact.

[0088] In this embodiment, each connecting component 151 includes four pressure rods 1511 arranged side by side at intervals along the Y direction; the pressure rods 1511 are L-shaped; each pressure rod 1511 includes a main pressure rod and a support rod, the main pressure rod extends along the Z direction for connecting to the inlet end 101 or outlet end 102 of the circuit breaker 100, the support rod extends along the X direction and slides through the fixing block 1512, and the main pressure rod is fixed to the top of the support rod; the main pressure rod is made of conductive material, the first end of the main pressure rod is used to connect to the inlet end 101 or outlet end 102, and the end of the main pressure rod is used to connect to the wire to connect the power supply; the first ends of the main pressure rods of both connecting components 151 are arranged facing the positioning mechanism 13; the second elastic member 1513 can be a spring, and the two ends of the second elastic member 1513 abut against the fixing block 1512 and the main pressure rod respectively.

[0089] See Figure 10 and Figure 11 The material gripping mechanism 25 includes clamping components, a third guide rail 252, and a material gripping fixing seat 251. The material gripping fixing seat 251 is mounted on the rotating seat 24. Two clamping components are arranged opposite each other and slidably mounted on the material gripping fixing seat 251 via the third guide rail 252. The two clamping components can move closer to or further away from each other. By providing two clamping components with adjustable spacing, the material gripping mechanism 25 can perform the actions of gripping and releasing the circuit breaker 100. That is, when the two clamping components move closer to each other, they can clamp the circuit breaker 100 from both sides; when the two clamping components move further away from each other, they can release the circuit breaker 100.

[0090] Furthermore, the material gripping mechanism 25 also includes a second transmission structure 253, a second rack, and a material gripping drive component 254. The second transmission structure 253 is rotatably mounted on the material gripping fixed base 251. Each gripping component is connected to a second rack, and both second racks mesh with the gears of the second transmission structure 253. The material gripping drive component 254 is connected to one of the gripping components, and drives the two gripping components to move closer or further apart through the second transmission structure 253 and the two second racks. By setting up the second transmission structure 253 and utilizing the gear and rack engagement, synchronous movement of the two gripping components can be achieved without the need for separate control of the two gripping components.

[0091] In this embodiment, one clamping assembly includes a clamping plate 255 and a first connecting plate 256, and another clamping assembly includes a clamping plate 255 and a second connecting plate 257. The material gripping drive 254 is a cylinder, and the material gripping drive 254 is connected to the first connecting plate 256 through a floating joint. A third guide rail 252 is provided on the material gripping fixing seat 251, and the third guide rail 252 extends along the Y direction. The first connecting plate 256 and the second connecting plate 257 are both slidably disposed on the material gripping fixing seat 251 through the third guide rail 252. The two clamping plates 255 are respectively fixed on the first connecting plate 256 and the second connecting plate 257. A second rack is connected to both the first connecting plate 256 and the second connecting plate 257, and the second racks on the first connecting plate 256 and the second connecting plate 257 mesh with the gears of the second transmission structure 253. By setting the gear and rack structure, the material gripping drive 254 drives one clamping assembly to move, which in turn drives the other clamping assembly to move synchronously.

[0092] In this embodiment, the material gripping fixing base 251 includes a material gripping base plate 2511, a material gripping side plate 2512, and a material gripping connecting plate 2513. The material gripping connecting plate 2513 and the material gripping base plate 2511 are arranged opposite each other along the X direction. There are two material gripping side plates 2512 arranged opposite each other along the Y direction. The material gripping side plates 2512 are fixed between the material gripping base plate 2511 and the material gripping connecting plate 2513 by bolts. The second transmission structure 253 and the third guide rail 252 are respectively arranged on both sides of the material gripping connecting plate 2513. The material gripping driving component 254 is a cylinder, and the cylinder is fixed on the material gripping base plate 2511 by a cylinder seat.

[0093] See Figure 1 , Figure 5 as well as Figure 12 The material gripping mechanism 25 also includes a material gripping support plate 2514, an auxiliary drive component 259, and a pusher component 260. The auxiliary drive component 259 is disposed on the material gripping fixed base 251. The pusher component 260 is connected to the auxiliary drive component 259 and is located below the clamping assembly. The auxiliary drive component 259 can drive the pusher component 260 to move away from the material gripping fixed base 251 to push against the circuit breaker 100.

[0094] In this embodiment, the material gripping fixing base 251 further includes a material gripping support plate 2514, which is disposed on the material gripping base plate 2511. An auxiliary driving member 259 is disposed on the side of the material gripping support plate 2514 away from the material gripping base plate 2511. A pushing member 260 is disposed on the auxiliary driving member 259. The auxiliary driving member 259 can drive the pushing member 260 to move so as to push the circuit breaker 100 against the positioning base plate 131.

[0095] By setting up an auxiliary drive component 259 and a pusher component 260, when the material grabbing mechanism 25 grabs the circuit breaker 100 and places the circuit breaker 100 on the positioning base plate 131, the auxiliary drive component 259 needs to drive the pusher component 260 to move along the X direction to ensure that the circuit breaker 100 fits against the positioning base plate 131 and that the groove 103 of the circuit breaker 100 can cooperate with the positioning strip 1311 on the positioning base plate 131. Then, the robot arm is controlled to move along the Y direction on the conveyor line 21 and continuously push the circuit breaker 100 along the Y direction until the end of the circuit breaker 100 abuts against the positioning end plate 132, and the placement of the circuit breaker 100 is completed.

[0096] See Figure 13 and Figure 14 The screw tightening mechanism 26 includes a mounting base, a bearing 264, a rotary drive component 262, and a screwdriver 267. The mounting base is disposed on the rotating base 24. The screwdriver 267 is rotatably disposed on the mounting base via the bearing 264. The rotary drive component 262 is disposed on the mounting base for driving the screwdriver 267 to rotate.

[0097] Specifically, the mounting base includes a mounting plate 261 and a bearing seat 265. The bearing seat 265 is disposed on the mounting plate 261, and the screwdriver 267 is rotatably disposed on the bearing seat 265 via the bearing 264. The mounting base also includes a support seat 263 disposed on the mounting plate 261, and a rotary drive component 262 is disposed on the support seat 263. The rotary drive component 262 can be a servo motor.

[0098] By setting bearing 264, screwdriver 267 is rotatably mounted on bearing seat 265 via bearing 264. This integrates the support and positioning of the rotatable screwdriver 267 into bearing 264, improving rotational accuracy, reducing friction, and ensuring stable rotation of screwdriver 267 at a specific position. In this embodiment, screw tightening mechanism 26 also includes a reducer, and rotary drive component 262 is mounted on support seat 263 via the reducer. Both bearing seat 265 and support seat 263 are bolted to mounting plate 261.

[0099] Optionally, the screw tightening mechanism 26 further includes a coupling 266 and a bushing 268. The screwdriver 267 rotates synchronously with the bushing 268. The screwdriver 267 is connected to the coupling 266 via the bushing 268 and to the rotary drive component 262 via the coupling 266. In this embodiment, the screwdriver 267 and the bushing 268 are connected by a pin 269; the screwdriver 267 engages with the bearing 264 via the bushing 268 and is rotatably mounted on the bearing seat 265.

[0100] The following is a detailed description of the usage process of the testing equipment:

[0101] The circuit breaker 100 is picked up by the material grabbing mechanism 25 of the operation module 20 and placed on the positioning mechanism 13 of the detection module 10. The positioning mechanism 13 of the detection module 10 can limit the circuit breaker 100 so that the circuit breaker 100 can be placed on the positioning mechanism 13 and will not fall off.

[0102] The operation module 20 exits the positioning mechanism 13 (ensuring no interference) and uses the rotating seat 24 to rotate the material gripping mechanism 25 to the screw tightening mechanism 26. The screw tightening mechanism 26 can tighten the wiring screws to the circuit breaker 100, ensuring that the metal plates of the circuit breaker 100 have uniform and flush angles.

[0103] After tightening, the screw tightening mechanism 26 is moved out, and the setting height and spacing of the two connecting components 151 in the detection module 10 are adjusted so that the pressure rods 1511 of the two connecting components 151 are connected to the inlet terminal 101 and outlet terminal 102 on both sides of the circuit breaker 100 to complete the detection. Then, the screw tightening mechanism 26 is switched to the material gripping mechanism 25 by rotating the rotating seat 24. The material gripping mechanism 25 can take the circuit breaker 100 that has completed the detection from the positioning mechanism 13 and transport it to the unloading line to complete the product unloading.

[0104] The testing equipment provided in this embodiment integrates the material gripping mechanism 25, the screw tightening mechanism 26, etc., to form a modular functional structure, which can reduce equipment occupancy and reduce equipment costs. It can also realize automatic feeding, online full inspection and automatic unloading of circuit breakers 100, and has high reliability and stability.
