[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] like Figure 1 As shown;

[0037] A test device for detecting overvoltage output by a power adapter comprises a base 1 and a detection controller body 2 mounted on the surface of the base 1.

[0038] In this embodiment: the factory will conduct sampling inspection on the power adapters before leaving the factory. The current inspection device needs to be fixed manually, which is very troublesome. In addition, workers have to take the power adapters one by one for inspection, which wastes a lot of time and has low work efficiency. On this basis, a feeding component 3 is added, which facilitates the automatic loading of the power adapters.

[0039] like Figure 1 、 Figure 2 Figure 6 and Figure 7 As shown:

[0040] In combination with the above content, in order to facilitate automatic loading of the power adapter, a feeding assembly 3 is also included that is installed under the base 1. The feeding assembly 3 includes a conveyor belt body 37, a conduit 38, a top plate 301 and an electric telescopic rod 302. A conveyor belt body 37 is provided under the base 1. A conduit 38 is fixedly installed at one end of the conveyor belt body 37 and located on the bottom surface of the base 1. A feed port is provided on the outer wall of the conduit 38 and at a position relative to one end of the conveyor belt body 37. An electric telescopic rod 302 is installed on the inner bottom surface of the conduit 38. The piston end of the electric telescopic rod 302 is fixedly installed with a top plate 301, and the top plate 301 is slidably connected in the conduit 38.

[0041] In this embodiment: when the power adapters are automatically loaded, the power adapters are placed one by one on the surface of the belt body provided with the conveyor belt body 37 below the base 1, and the conveyor belt body 37 is driven to rotate by the motor to transport the power adapters placed on the surface of the belt body of the conveyor belt body 37. Due to the outer wall of the conduit 38 and the feed port opened at a position relative to one end of the conveyor belt body 37, the power adapter can be put into the conduit 38 through the feed port opened on the surface of the conduit 38. In addition, because the inner bottom surface of the conduit 38 is installed with an electric telescopic rod 302, the piston end of the electric telescopic rod 302 is fixedly installed with a top plate 301, and the top plate 301 is slidably connected to the conduit 38, the extension of the piston end of the electric telescopic rod 302 can be driven to push the top plate 301 to slide inside the conduit 38, so as to lift the power adapter put into the conduit 38 to the surface of the base 1 for subsequent inspection.

[0042] It should be noted that a feed port is provided at a relative position at one end of the conveyor belt body 37, and a guide plate 39 is provided at an angle at the entrance of the feed port. This arrangement allows the power adapter to slide smoothly into the conduit 38 through the guide plate 39 when it slides off one end of the conveyor belt body 37.

[0043] In an optional embodiment: two hydraulic rods 32 are fixedly installed above the conveyor belt body 37 and on the bottom surface of the base 1, the piston ends of the two hydraulic rods 32 are connected to the connecting plate 33, and a plurality of groups of guide rods 34 are fixedly installed on the bottom surface of the connecting plate 33, and each group of guide rods 34 is fixedly connected to a baffle 36 at one end away from the connecting plate 33, and one side of the baffle 36 abuts against the surface of the belt body in the conveyor belt body 37.

[0044] In this embodiment: Based on this setting, when the power adapters are placed one by one on the conveyor belt body 37, the two hydraulic rods 32 fixedly installed on the bottom surface of the base 1 can be controlled to intermittently extend and retract, which can drive the connecting plate 33 connected to the piston ends of the two hydraulic rods 32 to follow up and fall, and a plurality of groups of guide rods 34 are fixedly installed on the bottom surface of the connecting plate 33, and each group of guide rods 34 is fixedly connected to a baffle 36 at one end away from the connecting plate 33, and one side of the baffle 36 abuts against the surface of the belt body in the conveyor belt body 37, so that the plurality of baffles 36 can intermittently block the power adapters on the conveyor belt body 37, so as to achieve intermittent transportation and avoid the power adapters from being pushed on the conveyor belt body 37.

[0045] It should be noted that only one power adapter needs to be blocked between every two adjacent baffles 36 .

[0046] It should be noted that: several groups of the baffles 36 and the conveyor belt body 37 are all provided with rubber pads on the side surface that abuts against each other, which can prevent the baffles 36 from scratching against the belt body in the conveyor belt body 37 when the baffles 36 are pressed down by the hydraulic rod 32. The rubber pads provided on the baffles 36 can also protect the surface of the power adapter.

[0047] In an optional embodiment, a U-shaped mounting bracket 31 is fixedly mounted on the bottom of the base 1 , and outer side walls of the plurality of guide rods 34 are slidably connected to holes formed on the surface of the U-shaped mounting bracket 31 .

[0048] In this embodiment: Based on this arrangement, when the hydraulic rod 32 is pressed down, it pushes several groups of guide rods 34 to slide down at the same time. The guide rods 34 can slide in the holes opened on the surface of the U-shaped mounting frame 31 to limit their position, thereby preventing the guide rods 34 from sliding down and driving one side of the baffle 36 to abut against the surface of the conveyor belt body 37, thereby preventing the force generated when the belt body in the conveyor belt body 37 rotates from driving the baffle 36 to deviate to one side.

[0049] In an optional embodiment, the outer side walls of several groups of guide rods 34 are each sleeved with a spring 1 35 , one end of the spring 1 35 abuts against the bottom surface of the connecting plate 33 , and the other end of the spring 1 35 abuts against the inner surface of the U-shaped mounting bracket 31 .

[0050] In this embodiment: through this arrangement, when the hydraulic rod 32 is pressed down, it pushes several groups of guide rods 34 to slide down at the same time, and when one side of the baffle 36 abuts against the surface of the conveyor belt body 37, the spring 1 35 can be compressed under the action of the force. At the same time, when the hydraulic rod 32 rises, when one side of the baffle 36 is separated from the surface of the conveyor belt body 37, the spring 1 35 can push the connecting plate 33 to rise under the action of its own elasticity, driving the baffle 36 to separate from the surface of the conveyor belt body 37. The set spring 1 35 can also reduce the weight of the connecting plate 33, guide rods 34 and baffle 36 borne by the piston end of the hydraulic rod 32.

[0051] It should be noted that the conveyor belt body 37 mainly consists of a motor, a transmission belt body and a mounting plate.

[0052] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 and Figure 9 As shown:

[0053] In combination with the above content, in order to facilitate the detection of the power adapter, it also includes a detection component 4 installed on the surface of the base 1 near the side of the detection controller body 2, the detection component 4 includes a cylinder 1 41, a splint 42, a power supply board 43, a cylinder 2 44, an L-shaped splint 1 45, an L-shaped splint 2 46, an insert rod 47, a fixing block 48, a slide bar 49, a spring 2 401, a slider 404 and a signal transmission block 405. Two cylinders 1 41 are symmetrically installed on the surface of the base 1, and the piston ends of the two cylinders 1 41 are fixedly installed with splints 42, and the power supply board 43 is fixedly installed on the side of the surface of the base 1 near the two splints 42, and the cylinder 2 44 is fixedly installed on the side of the surface of the base 1 near the two splints 42, and the slider 404 is fixedly installed on the piston end of the cylinder 2 44, and the slider 404 is slidably connected in the give way groove 403 opened on the surface of the L-shaped splint 1 45. An L-shaped clamping plate 2 46 is provided on one side of the L-shaped clamping plate 1 45, and an insertion rod 47 is integrally formed on the side of the L-shaped clamping plate 2 46 close to the L-shaped clamping plate 1 45, and a slot that matches the insertion rod 47 is opened on the surface of the side of the L-shaped clamping plate 1 45 close to the L-shaped clamping plate 2 46, and the L-shaped clamping plate 2 46 is slidably connected to one side of the L-shaped clamping plate 1 45 through the insertion rod 47 and this slot, and two fixed blocks 48 are fixedly installed on the outer surface of the side where the L-shaped clamping plate 1 45 and the L-shaped clamping plate 2 46 are close to each other, and the surfaces of the two fixed blocks 48 corresponding to each other in the horizontal direction are slidably connected with a sliding rod 49, and a spring 2 401 is provided on the surface of the sliding rod 49, and the two ends of the spring 2 401 are in contact with the surfaces of the two fixed blocks 48 corresponding to each other in the horizontal direction, and a signal transmission block 405 is provided on the inner surface of the L-shaped clamping plate 1 45, and the signal transmission block 405 is connected to the detection controller body 2 signal.

[0054] In this embodiment: first, the piston end of the electric telescopic rod 302 is driven to extend to push the top plate 301 to slide inside the conduit 38, so that the power adapter placed inside the conduit 38 can be lifted to the surface of the base 1. Then, the piston ends of the two groups of cylinders 41 symmetrically arranged on the surface of the base 1 are controlled to extend to push the two clamping plates 42 to move relative to each other, so that the L-shaped clamping plate 1 45 and the L-shaped clamping plate 2 46 between the two clamping plates 42 can be squeezed, so that the L-shaped clamping plate 2 46 can be close to the side of the L-shaped clamping plate 1 45 and the insertion rod 47 can be integrally formed. The slot that matches the plug rod 47 is opened on the side surface of the L-shaped clamping plate 1 45 near the L-shaped clamping plate 2 46, and the opening distance between the L-shaped clamping plate 1 45 and the L-shaped clamping plate 2 46 is adjusted until the power adapter is clamped between the L-shaped clamping plate 1 45 and the L-shaped clamping plate 2 46 (after the clamping is stable, the top plate 301 is driven to slide down to the opening of the guide tube 38 by controlling the contraction of the electric telescopic rod 1 302 to facilitate the lifting of the next power adapter). The L-shaped clamping plate 1 45 and the L-shaped clamping plate 2 46 are driven by the expansion and contraction of the cylinder 2 44. The power adapter between them is close to the side close to the power board 43, so that the power adapter can be inserted into the power board 43 for power-on detection. At the same time, the signal transmission block 405 set on the inner surface of the L-shaped clamping plate 1 45 can be plugged into the power adapter, so that the detected data can be sent to the integrated controller set in the detection controller body 2 through the signal transmission module set in the signal transmission block 405, and then the integrated controller sends it to the external terminal (which can detect the display unit of the controller body 2 and automatically sort it) through the transmission module, thereby achieving the effect of reducing manpower and improving efficiency. After the detection is completed, the control cylinder 2 44 contracts to unplug the power adapter from the power board 43, and at the same time control the two cylinders 1 41 to contract. After the power adapter is unplugged from the power board 43 to a certain distance, the two cylinders 1 41 are controlled to extend to clamp the power adapter between the two clamps 42 installed on the piston ends of the two cylinders 1 41. At this time, the control cylinder 2 44 continues to contract, and the power adapter can be unplugged from the signal transmission block 405, so that the power adapter can be removed.

[0055] It should be noted that: two fixed blocks 48 are fixedly installed on the outer surface of the side where the L-shaped splint 1 45 and the L-shaped splint 2 46 are close to each other, and the surfaces of the two fixed blocks 48 corresponding to each other in the horizontal direction are slidably connected with a slide rod 49, and the surface of the slide rod 49 is provided with a spring 2 401, and both ends of the spring 2 401 are in contact with the surfaces of the two fixed blocks 48 corresponding to each other in the horizontal direction, so as to cooperate with the sliding between the L-shaped splint 1 45 and the L-shaped splint 2 46 under the elasticity of the spring 2 401 itself, and both ends of the slide rod 49 are provided with a limit block to prevent the slide rod 49 from sliding off the surfaces of the two fixed blocks 48 corresponding to each other in the horizontal direction.
