Description

Technical Field

[0001] This invention specifically relates to a testing device for electrical automation equipment, and pertains to the field of testing equipment technology. Background Technology

[0002] With the rapid development of modern industry, electrical automation equipment is being used more and more widely in various fields, and the production scale of small electrical automation equipment is also constantly expanding. To ensure product quality, rigorous performance testing of equipment is required during the production process, including dimensional inspection, electrical parameter testing, and many other aspects. As a highly efficient automated testing method, automated inspection lines can achieve continuous and large-scale testing of small electrical automation equipment and have become the mainstream technical solution in the industry. However, in practical applications, existing automated inspection lines still have many technical shortcomings, which restrict further improvements in testing efficiency. First, existing testing lines lack effective and stable guiding mechanisms when conveying small electrical automation equipment. This makes the equipment prone to deviation, tilting, or misalignment on the conveyor belt, hindering accurate alignment of testing stations and severely impacting testing accuracy and stability. Second, the testing process often requires turning the equipment to ensure correct positioning of the surfaces to be tested, but current technology lacks flexible and reliable rotation and reversing devices, making equipment posture adjustment difficult. Furthermore, existing testing systems mostly rely on manual labor for testing equipment dimensions and electrical performance, lacking rapid and flexible testing capabilities and failing to meet the high-efficiency testing requirements of large-scale production. Simultaneously, the screening and transfer of equipment after testing are difficult to complete simultaneously, requiring significant manual intervention or complex mechanical structures. This not only increases labor costs but also results in low screening and transfer efficiency and slow transfer speeds, severely restricting overall testing efficiency. Therefore, it is necessary to propose a testing device for electrical automation equipment to address these issues. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide an electrical automation equipment testing device that can achieve stable guiding and conveying, flexible rotation and reversal, rapid detection and efficient screening and transfer, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a testing device for electrical automation equipment, comprising the equipment to be tested, a base, a rotating table rotatably disposed on the upper side of the base, a fixed plate fixedly installed on the upper side of the rotating table, and a double-conveyor frame installed on the upper side of the fixed plate for conveying. A lifting and rotating frame is movably installed in the middle of the fixed plate. This lifting and rotating frame is located in the middle of the spaced double conveyor frame and is used to lift and rotate the direction of the equipment being inspected. The fixed plate and the spaced double conveyor frame are equipped with detection clamps on the left and right sides for opening and closing and clamping the two sides of the equipment under inspection, and each detection clamp is equipped with an infrared ranging sensor that is set opposite to each other. Multiple bidirectional telescopic rods for pushing and pulling the displacement of the clamping plates on both sides are installed horizontally in the middle of the fixed plate. The bidirectional telescopic rods are installed through the middle of the spaced double conveyor frame. Rollers for rolling support of the inner side of the spaced double conveyor frame are rotatably installed on both sides of the bidirectional telescopic rods. The testing clamp is equipped with a movable frame plate that moves back and forth. A lifting plate is mounted on the upper side of the movable frame plate, and a plug-in power monitor for detecting the power of the equipment under test is installed on the lifting plate. An industrial vision camera and a grating sensor facing the equipment under test are installed on one side of the lifting plate.

[0005] A further improved design includes an external gear ring fixed to the outside of the rotating platform, a drive gear meshing with the external gear ring mounted on the base, and a drive motor for driving the drive gear to rotate inside the base.

[0006] A further improved scheme includes a double-conveyor frame comprising a front drive roller and a rear drive roller rotatably mounted on the front and rear sides of a fixed plate, with a first conveyor belt and a second conveyor belt spaced apart on the left and right sides of the front drive roller and the rear drive roller. A lifting and rotating frame is located between the first conveyor belt and the second conveyor belt, and a conveyor motor for driving the front drive roller and the rear drive roller to rotate is mounted on the fixed plate.

[0007] A further improved scheme includes a lifting rotating frame comprising a rotating motor installed in the middle of a fixed plate and a rotating seat rotatably embedded in the upper part of the fixed plate. The shaft end of the rotating motor is connected to the shaft of the rotating seat. The rotating motor is movably located in the middle cavity of the rotating table and the base. Multiple first vertical telescopic rods are installed in a ring array on the upper side of the rotating seat, and a top plate for supporting the bottom of the equipment under inspection is fixed at the top telescopic end of each first vertical telescopic rod. Multiple guide grooves are opened in a ring array on the upper side of the top plate, and an extension plate that slides outward is connected to the inner side of each guide groove. A limiting groove is opened on the lower side of the guide groove. The top surface of the extension plate is flush with the top surface of the top plate. A connecting rod is vertically fixed on the lower side of the extension plate, and the connecting rod extends through the limiting groove.

[0008] A further improved design includes a transmission mechanism on the underside of the top plate for driving each extension plate to slide along the limiting groove. The transmission mechanism includes a lower horizontal plate and an upper horizontal plate spaced apart vertically. Multiple uprights are fixed in a ring array around the outer periphery of the lower and upper horizontal plates, and the tops of the uprights are locked to the underside of the top plate. A first transmission motor is installed between the lower and upper horizontal plates. The shaft of the first transmission motor passes through the middle of the upper horizontal plate and is fitted with a rotating guide plate. The rotating guide plate is located on the underside of the top plate, and the middle of the rotating guide plate has a ring array of inclined grooves that are staggered with the limiting groove. The bottom end of the connecting rod passes downward through the middle of the inclined groove.

[0009] In a further improved design, each first vertical telescopic rod is slidably connected by a lower horizontal plate and an upper horizontal plate. A ball bearing is rotatably embedded on the opposite side of the top of the upright. A rotating groove adapted to fit and tighten with the ball bearing is opened on the outer circumference of the rotating guide plate. The upright is limited to rotating by the ball bearing and the rotating groove of the rotating guide plate.

[0010] A further improved design includes an outer frame rod integrally installed on one side of the testing clamp. A screw and a guide rod are longitudinally installed in the middle of the outer frame rod, and the screw and guide rod pass through the middle of the movable frame plate. The screw is threadedly connected to the movable frame plate, and a second drive motor for driving the screw rotation is installed on the outer frame rod.

[0011] A further improved design features an L-shaped rod locked to the lower side of the outer frame rod, with support slots on both sides of the fixing plate, and the lower side of the L-shaped rod slidingly passing through the support slots.

[0012] A further improved design features a plug-in power monitor with a plug interface on one side and a connector adapted to the plug interface on the side of the device under test. The plug-in power monitor is slidably mounted on the upper side of the lifting plate, and a horizontal telescopic rod for pushing the plug-in power monitor to move left and right is installed on one side of the lifting plate.

[0013] A further improved design includes a second vertical telescopic rod installed on the underside of the movable frame plate to push the lifting plate up and down.

[0014] By adopting the above technical solution, the present invention has the following advantages: The device of this invention has a simple and ingenious structure. By installing detection clamps on both sides of the double-layered conveyor frame, which can be relatively displaced to hold the inspected equipment in place, the double-layered conveyor frame can be stably limited and guided during transport. The detection clamps can also quickly determine the distance between the two detection clamps under the action of infrared ranging sensors, thereby determining the length of the inspected equipment. Moreover, the plug-in power monitor, industrial vision camera and grating sensor installed on the two detection clamps can be adjusted up, down, forward and backward, thereby flexibly adjusting the detection position. Therefore, when the inspected equipment passes through the grating sensor, the width of the inspected equipment can be detected in real time. Combined with the side information collected by the industrial vision camera, the size of the equipment can be determined. At the same time, it can be confirmed whether the plug of the inspected equipment corresponds to the plug interface of the plug-in power monitor. By moving the plug-in power monitor laterally, the plug interface is connected to the plug to realize power supply and perform power detection. Combined with the action of the rotating table, the entire double-layered conveyor frame can face the conveyor line in different directions, separating and transporting inspected equipment of different sizes and those with faults, greatly improving the efficiency of equipment inspection and powder screening. Meanwhile, when the testing surface of the equipment under test does not correspond to the plug-in power monitor, the two testing clamps can be opened, and the equipment under test can be lifted and rotated by the lifting and rotating frame to make the testing surface of the equipment under test correspond to the plug-in interface of the plug-in power monitor, thereby improving the efficiency and flexibility of equipment use; and during the lifting and rotating frame lifting, the various extension plates can be extended outward to increase the support surface with the bottom of the equipment under test, thereby improving the stability of lifting and rotating the equipment under test. In addition, a bidirectional telescopic rod was designed on the fixed plate. The bidirectional telescopic rod can not only control the relative movement of the detection clamps on the left and right sides synchronously, but also the rollers rotating on the bidirectional telescopic rod can provide rolling support for the middle of the first and second conveyor belts of the double-conveyor frame, thereby improving the structural strength and conveying stability of the double-conveyor frame.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-11 As shown, the present invention provides a testing device for electrical automation equipment, including a device under test 10, a base 1, a rotating platform 2 rotatably mounted on the upper side of the base 1, a fixed plate 21 fixedly mounted on the upper side of the rotating platform 2, and a double-layered conveyor frame 3 mounted on the upper side of the fixed plate 21 for conveying. In order to realize the rotation direction of the rotating platform 2 and the double-layered conveyor frame 3, an external gear ring 22 is fixedly provided on the outer side of the rotating platform 2. A drive gear 23 that meshes with the external gear ring 22 is installed on the base 1, and a drive motor for driving the drive gear 23 to rotate is installed inside the base 1. The spaced double conveyor frame 3 includes a front drive roller 31 and a rear drive roller 32 rotatably mounted on the front and rear sides of the fixed plate 21. The front drive roller 31 and the rear drive roller 32 are connected to the left and right sides by a first conveyor belt 33 and a second conveyor belt 34 at intervals. The lifting and rotating frame 4 is located between the first conveyor belt 33 and the second conveyor belt 34. The fixed plate 21 is equipped with a conveyor motor 35 for driving the front drive roller 31 and the rear drive roller 32 to rotate. Therefore, the transmission of the conveyor motor 35 can make the first conveyor belt 33 and the second conveyor belt 34 rotate synchronously for conveying.

[0018] A lifting and rotating frame 4 is movably installed in the middle of the fixed plate 21. This lifting and rotating frame 4 is located in the middle of the spaced double conveyor frame 3 and is used to lift and rotate the direction of the device under inspection 10. The fixed plate 21 and the spaced double conveyor frame 3 are provided with detection clamps 5 on the left and right sides for opening and closing to clamp the sides of the device under inspection 10. Each detection clamp 5 is equipped with an infrared distance sensor 8 arranged opposite to each other to detect the distance between the two detection clamps 5, thereby determining the length of the front and rear sides of the device under inspection 10. A plurality of bidirectional telescopic rods 7 are horizontally installed in the middle of the fixed plate 21 for pushing and pulling the displacement of the detection clamps 5 on both sides. The bidirectional telescopic rods 7 are inserted through the middle of the spaced double conveyor frame 3. The bidirectional telescopic rods 7 are rotatably installed on both sides for rolling support inside the spaced double conveyor frame 3. The side rollers 71 make the double conveyor frame 3 more stable during conveying. Furthermore, the lower side of the outer frame rod 52 is locked with an L-shaped rod 57. Support slots 24 are provided on both sides of the fixing plate 21, and the lower side of the L-shaped rod 57 slides through the support slots 24. This allows the L-shaped rod 57 to further assist in supporting the components installed on the inspection clamp 5, thereby improving the smoothness of the opening and closing of the inspection clamp 5. Additionally, the inspection clamp 5 is movably equipped with a movable frame plate 51. A lifting plate 6 is mounted on the upper side of this movable frame plate 51, and a plug-in power monitor 61 for detecting the power of the inspected equipment 10 is installed on the lifting plate 6. An industrial vision camera 64 and a grating sensor 65 facing the inspected equipment 10 are installed on one side of the lifting plate 6. Through detection… A movable frame plate 51 is installed on the clamping plate 5, which moves back and forth. A lifting plate 6 is installed on the movable frame plate 51, and an industrial vision camera 64 and a grating sensor 65 are installed on one side of the lifting plate 6. A plug-in power monitor 61 is also installed on the lifting plate 6, which slides left and right. Therefore, the plug-in power monitor 61, the industrial vision camera 64, and the grating sensor 65 can adjust their positions on the clamping plate 5, thus flexibly adjusting the detection position. Therefore, when the inspected equipment 10 passes the grating sensor 65, the width of the inspected equipment 10 can be detected in real time. Combined with the side information of the inspected equipment 10 collected by the industrial vision camera 64, the size of the equipment can be determined. At the same time, it can be confirmed whether the plug 11 of the inspected equipment 10 corresponds to the plug-in power monitor. The plug-in interface 62 of the monitor 61, through the lateral movement of the plug-in power monitor 61, connects the plug-in interface 62 to the plug connector 11 for power supply and power detection. Combined with the function of the rotating table 2, the entire interval double conveyor frame 3 can be oriented towards the conveyor lines in different directions, separating and conveying the inspected equipment 10 of different sizes and those with faults, greatly improving the efficiency of equipment inspection and powder screening. At the same time, when the inspection surface of the inspected equipment 10 does not correspond to the plug-in power monitor 61, the two inspection clamps 5 can be opened to make room, and the inspected equipment 10 can be lifted and rotated by the lifting rotating frame 4 to make the inspection surface of the inspected equipment 10 correspond to the plug-in interface 62 of the plug-in power monitor 61, improving the efficiency and flexibility of equipment use.

[0019] The lifting rotating frame 4 includes a rotating motor 40 installed in the middle of the fixed plate 21 and a rotating seat 41 rotatably embedded in the upper side of the fixed plate 21. The shaft end of the rotating motor 40 is connected to the rotating seat 41. The rotating motor 40 is movably located in the middle cavity of the rotating table 2 and the base 1. Six first vertical telescopic rods 42 are installed in a ring array on the upper side of the rotating seat 41. The top telescopic end of each first vertical telescopic rod 42 is fixed with a top plate 43 for supporting the bottom of the device under inspection 10. Six guide grooves 44 are opened in a ring array on the upper side of the top plate 43. An extension plate 45 that slides outward is connected to the inner side of each guide groove 44. A limit groove 431 is opened on the lower side of the guide groove 44. The top surface of the extension plate 45 is flush with the top surface of the top plate 43. In this way, when the extension plate 45 extends outward, it can increase the area of ​​the bottom of the device under inspection 10, making it more stable to use. A connecting rod 451 is vertically fixed to the lower side of the extension plate 45, and the connecting rod 451 extends through the limiting groove 431. Thus, the connecting rod 451 and the lower side of the top plate 43 are provided with a transmission mechanism 46 for driving each extension plate 45 to slide along the limiting groove 431. The transmission mechanism 46 includes a lower horizontal plate 461 and an upper horizontal plate 462 spaced vertically apart. Multiple uprights 463 are fixed in a circular array around the outer periphery of the lower horizontal plate 461 and the upper horizontal plate 462, and the tops of the uprights 463 are locked to the lower side of the top plate 43. A first drive motor 464 is installed between the lower horizontal plate 461 and the upper horizontal plate 462. The rotating shaft of 4 passes through the middle of the upper horizontal plate 462 and is equipped with a rotating guide plate 465. The rotating guide plate 465 is located on the lower side of the top plate 43. The rotating guide plate 465 has a ring array of inclined grooves 4651 that are staggered with the limiting slide groove 431 in the middle. The bottom end of the connecting rod 451 passes through the middle of the inclined groove 4651 downward. In this way, the first drive motor 464 can drive the rotating guide plate 465 to rotate through the rotating shaft. The inclined groove 4651 of the rotating guide plate 465 pushes the connecting rod 451 to slide along the limiting slide groove 431, thereby realizing that the six extension plates 45 extend outward or retract synchronously. This structure is simple and ingenious, and the structure is stable.

[0020] Furthermore, the design incorporates six first vertical telescopic rods 42 that are slidably connected by a lower horizontal plate 461 and an upper horizontal plate 462. This design enhances the overall structural strength and stability of each first vertical telescopic rod 42, preventing individual rods from shifting or falling off. Additionally, ball bearings 4631 are rotatably embedded on opposite sides of the top of each upright rod 463. A rotating groove 4652, fitted and tightened to the ball bearings 4631, is provided on the outer circumference of the rotating guide plate 465. The upright rod 463 is limited in rotation by the ball bearings 4631 and the rotating groove 4652 of the rotating guide plate 465. This design ensures greater stability of the rotating guide plate 465 during rotation, preventing tilting and maintaining its horizontal rotation.

[0021] To ensure stable forward and backward displacement of the components mounted on the movable frame plate 51 and the lifting plate 6, an outer frame rod 52 is integrally provided on one side of the detection clamping plate 5. A screw rod 53 and a guide rod 54 are longitudinally installed in the middle of the outer frame rod 52, and the screw rod 53 and guide rod 54 pass through the middle of the movable frame plate 51. The screw rod 53 is threadedly connected to the movable frame plate 51. A second drive motor 56 is installed on the outer frame rod 52 to drive the rotation of the screw rod 53. Therefore, the second drive motor 56 drives the screw rod 53. The screw rod 53 threadedly drives the lifting plate 6 and the forward and backward movement of the lifting plate 6.

[0022] In this embodiment, in order to perform electrical testing on the device under test 10, a plug-in interface 62 is provided on one side of the plug-in power monitor 61, and a plug connector 11 adapted to the plug-in interface 62 is installed on one side of the device under test 10. The plug-in power monitor 61 is slidably mounted on the upper side of the lifting plate 6. A horizontal telescopic rod 63 for pushing the plug-in power monitor 61 to move left and right is installed on one side of the lifting plate 6. Therefore, when the plug connector 11 of the device under test 10 corresponds to the plug-in interface 62 of the plug-in power monitor 61, the device under test 10 and the plug-in power monitor 61 can be electrically connected by pushing the horizontal telescopic rod 63. In order to allow the plug-in interface 62 of the plug-in power monitor 61 to adjust its height to accommodate plug connectors 11 of different sizes and heights of the device under test 10, a second vertical telescopic rod 66 for pushing the lifting plate 6 to rise and fall is installed on the lower side of the movable frame plate 51. The height position of the plug-in power monitor 61 is controlled by the extension and retraction of the second vertical telescopic rod 66, which is simple and flexible to use.

[0023] In a more specific embodiment, during use, the device under test 10 is placed on the first conveyor belt 33 and the second conveyor belt 34 of the double-conveyor frame 3. The two detection clamps 5 move relative to each other synchronously via the bidirectional telescopic rod 7, and are positioned against the left and right sides of the device under test 10 for correction and limitation. When the detection clamps 5 move left and right, the L-shaped rod 57 installed on the lower side of the outer frame rod 52 can simultaneously slide and support on the support socket 24, ensuring the structural stability of the detection clamps 5. At this time, the length of the device under test 10 can be determined simultaneously under the action of the infrared ranging sensor 8 and fed back to the external control system. Then, the conveyor motor 35 drives the front drive roller 31, the rear drive roller 32, the first conveyor belt 33, and the second conveyor belt 34 to rotate forward and transport the device under test 10. The detection clamps 5, in conjunction with the first conveyor belt 33 and the second conveyor belt 34, guide and transport the device under test 10. During transport, the bidirectional telescopic rod... The rollers 71 mounted on the 7 can simultaneously provide rolling support to the inner side of the middle of the first conveyor belt 33 and the second conveyor belt 34 to improve the smoothness of the conveying of the first conveyor belt 33 and the second conveyor belt 34. When the device under inspection 10 is conveyed to the top of the lifting and rotating frame 4, the second drive motor 56 of one side detection clamp 5 drives the screw 53, and the screw 53 drives the moving frame plate 51 to move forward, so that the grating sensor 65 mounted on the lifting plate 6 can move back and forth along one side of the device under inspection 10. The number of blocked light beams reflects its size in the width direction and feeds back to the peripheral control system. Meanwhile, the second drive motor 56 of the other side detection clamp 5 drives the moving frame plate 51, the industrial vision camera 64 and the plug-in power monitor 61 to be located in the middle of the side of the device under inspection 10. The industrial vision camera 64 is used to detect whether the plug 11 side of the device under inspection 10 is facing both sides of the detection clamp 5. When the inspection surface of the device under inspection 10 does not correspond to the side of the inspection clamp 5, the two inspection clamps 5 first open the restrictive space under the action of the bidirectional telescopic rods 7, and appropriately raise the top plate 43 by lifting each of the first vertical telescopic rods 42 of the rotating frame 4, so that the top plate 43 is slightly higher than the upper side of the first conveyor belt 33 and the second conveyor belt 34. As the top plate 43 rises, the transmission mechanism 46 synchronously guides the displacement upward along the first vertical telescopic rods 42. Then, the first transmission motor 464 drives the rotating guide plate 465 to rotate clockwise, and the rotating groove 4652 of the rotating guide plate 465 rotates on each of the uprights 463. When the bead 4631 rotates clockwise, the guide plate 465 rotates clockwise, and the connecting rods 451 are pushed outward along the limiting slide groove 431 by the inclined grooves 4651, so that the extension plates 45 extend outward along the guide slide groove 44, increasing the support area with the bottom of the device under inspection 10, thereby improving the lifting stability. Then, the rotary motor 40 drives the first vertical telescopic rod 42, the top plate 43 and the extension plate 45 components installed above the rotary seat 41 to rotate 90 degrees, so that the device under inspection 10 can quickly turn and the plug 11 side of the device under inspection 10 is aligned with the plug-in type. The plug interface 62 of the power monitor 61, which is the detection surface of the device under test 10, aligns with one side of the detection clamp 5. At this time, the detection clamp 5 clamps the device under test 10 again. The infrared distance sensor 8 can be used to confirm whether the width detected by the grating sensor 65 is correct, ensuring the accuracy of the detection dimensions. Then, the industrial vision camera 64 detects the specific position of the connector 11. The screw 53 moves back and forth, and the second vertical telescopic rod 66 moves up and down to make the plug interface 62 of the plug-in power monitor 61 align with the connector 11. The horizontal pushing action of the horizontal telescopic rod 63 further facilitates this alignment. The connector 11 of the device under test 10 is inserted into the connector 62 of the plug-in power monitor 61. Then, power is supplied to both the plug-in power monitor 61 and the device under test 10. The power of the device under test 10 is then tested using the plug-in power monitor 61. After testing, the plug-in power monitor 61 and the lifting and rotating frame 4 are reset. The device under test 10 is then transported to the corresponding production line via the spaced double conveyor frame 3. Specifically, the drive gear 23 can be rotated by the drive motor on the base 1. The drive gear 23 meshes with the external gear ring 22 to rotate, thereby controlling the orientation of the spaced double conveyor frame 3. Figure 11 As shown, two different sizes of the tested equipment 10 and the tested equipment 10 with unqualified electrical test can be transported separately, which greatly improves the efficiency of equipment testing and transportation and the flexibility of equipment use.
