[0021] like Figures 1 to 4 As shown, a support plate 2 is arranged on a frame 1, and the support plate 2 is used to carry the device to be detected; a detection mechanism 3 is arranged on the frame 1 in a movable manner to approach or move away from the support plate 2; a turntable 4 is arranged on the frame 1 in a movable manner to approach or move away from the support plate 2, and the turntable 4 is used to drive the plug 5 to rotate; a plurality of plugs 5 are arranged on the movable end of the turntable 4, and the plugs 5 can be flipped relative to the movable end of the turntable 4; As shown in the above structure, when the electrical inspection tool is used, the device to be inspected is placed on the support plate 2, and then the turntable 4 drives the plug 5 to rotate, so that the corresponding plug 5 can be selected and aligned with the electrical slot of the device to be inspected. Then, the turntable 4 is moved, and the plug 5 can be inserted into the electrical slot of the device to be inspected to realize automatic power supply; finally, the detection mechanism 3 is moved toward the device to be inspected, so as to realize the electrical inspection of the device to be inspected; This structure arranges a plurality of plugs 5 on the turntable 4, so that the plugs 5 can be switched through the turntable 4 according to the needs of the product to be tested, so as to realize rapid power supply, which is conducive to ensuring that the tooling is suitable for application scenarios requiring mixed production of different types of products and requiring rapid switching of plugs; Specifically, the detection mechanism 3 uses an electrical detection probe to implement electrical detection work; In this structure, the plug 5 is configured as a flippable structure, so that the plug 5 can be easily flipped when the machine is shut down to detect whether the plug 5 is damaged or has broken pins, thereby ensuring that the plug 5 is intact and has no problems, thereby ensuring the safety and reliability of electrical detection.

[0022] like Figure 1 As shown, the first displacement mechanism 6, the second displacement mechanism 7 and the third displacement mechanism 8 are all arranged on the frame 1; the support plate 2 is arranged on the first displacement mechanism 6; the detection mechanism 3 is arranged on the second displacement mechanism 7; and the turntable 4 is arranged on the third displacement mechanism 8; As in the above structure, the first displacement mechanism 6 can drive the support plate 2 away from or close to the detection mechanism 3, so as to facilitate loading and unloading work; specifically, the first displacement mechanism 6 adopts a linear displacement module; The second displacement mechanism 7 can drive the detection mechanism 3 to move so as to selectively move it closer to or farther away from the device to be detected; specifically, the second displacement mechanism 7 can be an electric push rod or a cylinder; The third displacement mechanism 8 can drive the turntable 4 and the plug 5 to selectively approach the device to be detected, and insert or remove the plug 5 from the electrical slot of the device to be detected; specifically, the third displacement mechanism 8 can adopt a linear displacement module.

[0023] like Figures 5 to 7 As shown, the turntable 4 includes a turntable body 41, a turntable 42, an assembly ring 43 and a support ring 44, wherein the turntable 42 is arranged on the turntable body 41, and the turntable 42 is the movable end of the turntable 4; the assembly ring 43 is arranged on the turntable 42, the plug 5 is rotatably connected with the assembly ring 43, and the diameter line of the turntable 42 is perpendicular to the rotation axis of the plug 5; the support ring 44 is connected to the turntable body 41 to support the plug 5, so that the axis of the plug 5 is perpendicular to the axis of the turntable 42; As in the above structure, in the turntable 4, the turntable body 41 drives the turntable 42 to rotate, and then the turntable 42 drives the assembly ring 43 and the plug 5 to rotate, so as to realize the switching of the plug 5. This structure facilitates the removal of the assembly ring 43 and the plug 5 at the same time, so as to carry out maintenance work; The plug 5 is rotatably connected to the assembly ring 43, so that the plug 5 can be flipped, which is convenient for checking the plug 5. The inspection does not require the assembly ring 43 to be removed from the turntable 42. Specifically, the turntable body 41 can adopt a worm gear or gear drive structure; Since the plug 5 will rotate and switch, and also needs to remain flippable, a support ring 44 is provided to support the plug 5 to ensure that the plug 5 can maintain a stable posture when rotating and does not interfere with the flipping of the plug 5.

[0024] like Figures 5 to 8 As shown, the assembly ring 43 includes a connecting block 431 and a rotating shaft 432, and the plug 5 includes a shaft cylinder 51, a telescopic rod 52 and an electrical connector 53, wherein the connecting blocks 431 are arranged in a circular array with the axis of the rotating disk 42 as a reference, and a gap is left between the connecting blocks 431; a rotating shaft 432 is arranged between any two adjacent connecting blocks 431, and the rotating shaft 432 and the connecting block 431 are detachably connected; As in the above structure, in the assembly ring 43, the connection block 431 is connected to the turntable 42, and the rotation shaft 432 is used to connect the connection block 431 in series, and the plug 5 is installed at the same time, so that the plug 5 can realize the flipping action; At the same time, the connecting block 431 and the rotating shaft 432 in this structure are detachable structures, so it is convenient to remove the plug 5 on the rotating shaft 432 for replacement and maintenance.

[0025] Specifically, Figure 8 As shown, the shaft cylinder 51 is sleeved on the rotating shaft 432; one end of the telescopic rod 52 is connected to the shaft cylinder 51, and the other end is connected to the electrical connector 53, and the telescopic rod 52 has a pre-tightening force to move toward the shaft cylinder 51; when the telescopic rod 52 is extended, the electrical connector 53 is plugged into the device to be detected; when the telescopic rod 52 is retracted, the electrical connector 53 overlaps the support ring 44; As in the above structure, the plug 5 is directly sleeved on the rotating shaft 432 of the assembly ring 43 through the shaft tube 51, so that after the rotating shaft 432 and the connecting block 431 are separated, the plug 5 can be removed as a whole; The telescopic rod 52 is used for displacement of the plug 5. In this case, the plug 5 and the device to be detected do not need to be connected by displacement of the turntable 4. Instead, an independent driving mechanism is provided to realize the extension and retraction of the telescopic rod 52, so that the electrical connector 53 can be inserted into the electrical slot of the device to be detected and can be removed. The telescopic rod 52 is provided with a retracting pre-tightening force to facilitate the electrical connector 53 to be separated from the device to be tested; Specifically, the telescopic rod 52 may be formed by two sleeved cylinders, and a tension spring may be provided inside to maintain a retracted pre-tightening force so that the cylinder that is away from the cylinder may be displaced toward the shaft cylinder 51 .

[0026] like Figure 6As shown, the turntable 4 further includes a driving member 45, and the support ring 44 includes a bracket 441 and a ring body 442, wherein three brackets 441 are provided, and the three brackets 441 and the driving member 45 are arranged in a circular array with the axis of the turntable 42 as a reference, and are connected to the turntable body 41; the ring body 442 is arranged on the bracket 441 and the driving member 45; the driving member 45 is used to drive the telescopic rod 52 to be telescopic; As in the above structure, the drive member 45 is provided to realize the displacement of the plug 5, so that the turntable 4 and the plug 5 can be synchronously displaced for plugging without moving the turntable 4; Specifically, when the driving member 45 is arranged, it is integrated with the turntable body 41 and the support ring 44, wherein the ring body 442 is connected to the turntable body 41 through the bracket 441 and the driving member 45, the bracket 441 and the driving member 45 play a supporting role together, and the ring body 442 supports the electrical connector 53 of the plug 5, so that when the turntable 42 drives the plug 5 to rotate and switch, the posture of the plug 5 can be guaranteed to be stable; When plugging in power, the corresponding plug 5 is rotated to move to the driving member 45, and the driving member 45 drives the plug 5 to move, so that the device to be detected can be plugged in.

[0027] like Figures 9 to 16 As shown, the driving member 45 includes a carrier 451, a slide rail 452, a slider 453, a guide rod 454, a push plate 455, a limit block 456 and a cylinder 457, wherein the carrier 451 is arranged on the turntable body 41; the slide rail 452 is arranged on the carrier 451; the slider 453 is slidably matched with the slide rail 452; the guide rod 454 is arranged on the slider 453, and the guide rod 454 is parallel to the slide rail 452; the push plate 455 is slidably arranged on the guide rod 454, the top end of the push plate 455 is provided with a slot 401, and the side of the push plate 455 facing the slider 453 is provided with a first inclined The first inclined surface 402 is provided with a second inclined surface 403 on the slider 453 corresponding to the first inclined surface 402, and a plane 404 is provided in the middle of the second inclined surface 403; the width of the slider 453 is smaller than the width of the push plate 455; a limit plate 521 spaced from the electrical connector 53 is provided on the telescopic rod 52, and the telescopic rod 52 has a retracting preload; a limit block 456 is provided on the side of the push plate 455 away from the slider 453, and the limit block 456 is connected to the carrier 451; a cylinder 457 is provided on the carrier 451, and a movable end of the cylinder 457 is connected to the slider 453; As in the above structure, the driving member 45 is used to realize the displacement of the plug 5 by driving the telescopic rod 52 to extend and retract so that the electrical connector 53 is plugged into the electrical slot of the device to be detected; when the electrical connector 53 is driven by the rotating disk 42 to move to the top of the driving member 45, the driving member 45 performs the action; like Fig.11As shown, it is the initial state of the driving member 45, at this time, the electrical connector 53 is overlapped on the support ring 44, and the slider 453 is relatively separated from the push plate 455. When the electrical connector 53 needs to be docked, the cylinder 457 is actuated; like Fig.12 As shown, at this time, the cylinder 457 drives the slider 453 to move to abut against the push plate 455, and the second inclined surface 403 of the slider 453 contacts the first inclined surface 402 of the push plate 455. Restricted by the stop block 456, the push plate 455 moves upward to be clamped between the electrical connector 53 and the stop plate 521 through the slot 401; at the same time, the plane 404 on the second inclined surface 403 supports the push plate 455 to ensure the stability of the push plate 455; The guide rod 454 is used to support the push plate 455. Fig. 9 It can be seen that a strip groove is provided at the portion of the guide rod 454 that passes through the push plate 455 to avoid interfering with the up and down displacement of the push plate 455; specifically, the center of gravity of the push plate 455 is located at the lower end, which can prevent the push plate 455 from tilting to ensure a correct posture; like Fig.13 As shown, the cylinder 457 then continues to move, and the push plate 455 can be driven to move through the slider 453, and the push plate 455 will drive the electrical connector 53 to move, so as to automatically power the front detection equipment when plugged in, and the telescopic rod 52 will be extended synchronously; In this structure, the slider 453 is configured as an electromagnet to attract and fix the push plate 455 when pushing the electrical connector 53 to move, so as to prevent the push plate 455 from being loose, thereby allowing the electrical connector 53 to be better stressed.

[0028] In this structure, it is necessary to ensure that the width of the slider 453 is smaller than the width of the push plate 455, so that when the slider 453 moves along the slide rail 452, it will not be blocked by the limit block 456, and the push plate 455 will be blocked, so that the slider 453 can push up the push plate 455; Meanwhile, when the push plate 455 drives the electrical connector 53 to move, the top surface of the limit block 456 will support the push plate 455 to ensure the stability of the movement of the push plate 455 and prevent the push plate 455 from being separated from the telescopic rod 52 .

[0029] In this structure, Fig.17 As shown, it is necessary to control the distance between the plug 5 and the limit block 456, that is, before the lower end of the push plate 455 is higher than the limit block 456, the slot 401 of the push plate 455 is connected to between the limit plate 521 and the electrical connector 53, so that after the lower end of the push plate 455 is higher than the top surface of the limit block 456, it can still rise stably to clamp the telescopic rod 52.

[0030] like Fig.14As shown, after the electrical inspection is completed, the cylinder 457 retracts. Although the telescopic rod 52 is provided with a retracting preload, this preload is insufficient to cause the electrical connector 53 to be separated from the electrical slot of the device to be inspected, and is only used for auxiliary purposes. As the cylinder 457 drives the slider 453 to move, the end of the guide rod 454 will abut against the side of the push plate 455 away from the slider 453, thereby driving the push plate 455 and the electrical connector 53 to retract, so that the electrical connector 53 is separated from the electrical slot of the device to be tested; At this time, the status is Fig.15 As shown, the push plate 455 is separated from the top surface of the limit block 456, and then automatically falls back and separates from the telescopic rod 52, and resumes as shown in FIG. Fig.11 The structure shown.
