Description

[0002] The two ends of the wire are respectively the electrical plug end and the power plug end (the present invention is a three-plug). The insulation performance of the connection between the plug and the wire is related to the safety of electricity use. If the connection is easily broken down, that is, the insulation performance is insufficient, it is easy to cause electricity accidents.

[0003] like Figure 8 The plug insulation performance detection device of the prior art is provided with two opposing cylinders, and the piston rod end of the cylinder is provided with an insulation test soft block, and the insulation test soft block uses an insulating material to wrap the internal conductor. When the two insulation test soft blocks clamp the plug, the insulation performance of the plug connection is determined by detecting the leakage current caused by the breakdown of the plug connection. However, the plug insulation performance detection device of the prior art requires manual plugging and unplugging of the plug to be tested, resulting in low detection efficiency and high false detection rate.

The power plug transverse slide 34 is fixedly connected with a power plug clamp 341. The useful electrical plug transverse slide 35 is fixedly connected with a useful electrical plug clamp 351.

[0033] See Figure 2 The slide 2 is provided with a pit 21, and a lower cylinder 22 is provided in the pit 21 (see Figure 7), the piston rod of the lower cylinder 22 is fixedly connected with a lower insulation test soft block 221. The rear side of the chain transmission mechanism 1 is provided with a test mechanism 4, the test mechanism 4 is provided with an upper cylinder 41, the piston rod of the upper cylinder 41 is fixedly connected with an upper insulation test soft block 411, the upper insulation test soft block 411 and the lower insulation test soft block 221 can be close to each other to simultaneously clamp the electrical plug connection and the power plug connection of the same wire 5 (reference Figure 2 ).

[0034] Specifically, see Figure 3 The chain transmission mechanism 1 is provided with a motor 13 and a reducer 14, the output shaft of the reducer 14 is provided with a sprocket, and the sprocket is connected with a chain.

[0035] Specifically, see Figure 5 The connecting seat 331 is provided with a power plug plug-in cylinder 342, and the piston rod of the power plug plug-in cylinder 342 is fixedly connected to the power plug transverse sliding seat 34.

[0036] Specifically, see Figure 5 The connecting seat 331 is provided with an electrical plug plugging and unplugging cylinder 352, and the piston rod of the electrical plug plug plugging and unplugging cylinder 352 is fixedly connected to the electrical plug transverse sliding seat 35.

[0037] Specifically, the longitudinal frame 31 is provided with a longitudinal screw rod 36 , the longitudinal slide seat 33 is fixedly connected with a screw rod nut 332 , and the longitudinal screw rod 36 is threadedly connected to the screw rod nut 332 .

[0038] Specifically, the longitudinal frame 31 is provided with a moving motor 13, and the moving motor 13 is connected to the longitudinal screw rod 36 through a belt.

[0039] The working principle of the automatic detection device for plug insulation performance of the present invention is as follows:

[0040] A wire transfer device (not shown) is provided at the rear side of the plug insulation performance automatic detection device. The wire transfer device is provided with multiple pairs of transfer jigs (not shown). The transfer jigs are provided with power plug jacks and electrical appliance plug jacks. The wire to be tested 5 (reference Figure 1 ) are respectively inserted into the power plug jack and the electrical appliance plug jack, so that the wire 5 to be tested can move forward with the transfer fixture.

[0041] When the transfer fixture moves to the front side, the power plug clamping jaw 341 and the electrical plug clamping jaw 351 both move backward and clamp the two ends of the wire 5 to be tested respectively. Then, the power plug plugging cylinder 342 and the electrical plug plugging cylinder 352 both extend outward to pull out the two ends of the wire 5 to be tested.

[0042] Then, the power plug clamp 341 and the appliance plug clamp 351 are moved forward to a suitable position, so that the two ends of the wire 5 to be tested are aligned with the chain feeding position ( Figure 1After alignment, the power plug carrier 11 and the electrical plug carrier 12 are aligned. After alignment, the power plug plug cylinder 342 and the electrical plug plug cylinder 352 are both retracted, so that the power plug of the wire 5 to be tested is inserted into the power plug carrier 11, and the electrical plug of the wire 5 to be tested is inserted into the electrical plug carrier 12.

[0043] Then, the upper chain segment moves forward by a distance corresponding to a pair of sockets (a power plug carrier 11 and an electrical plug carrier 12), so that the empty pair of sockets (same as above) moves to the chain loading position ( Figure 1 The other multiple pairs of sockets connected to the multiple wires 5 to be tested move forward along the slide 2. When a wire 5 to be tested moves between the lower insulation test soft block 221 and the upper insulation test soft block 411 (such as Figure 2 The lower insulation test block 221 and the upper insulation test block 411 are close to each other and clamp the wire connection of the power plug of the wire 5 to be tested and the electrical plug. The lower insulation test block 221 and the upper insulation test block 411 are both charged. If the circuit formed by the lower insulation test block 221 and the upper insulation test block 411 is connected, that is, the wire connection of the power plug of the wire 5 to be tested and the electrical plug is broken down, and the insulation performance does not meet the standard.

[0044] After the test is completed, the wire 5 to be tested continues to move forward with the chain, and the material taking mechanism (not shown) arranged at the front side of the present invention will take away the wire 5 at the front end of the chain and transfer it to the next detection device.

[0045] The plug insulation performance automatic detection device of the present invention uses a pair of power plug carriers 11 and electrical plug carriers 12 to carry the wire 5 to be tested, and drives multiple pairs of socket carriers to move intermittently through chains. When the wire 5 to be tested moves to the detection station, the lower insulation test soft block 221 and the upper insulation test soft block 411 clamp the power plug of the wire 5 to be tested and the wire connection of the electrical plug, so as to quickly detect the insulation performance of the joints at both ends of the wire 5 to be tested. The above process does not require manual participation, thereby improving the detection efficiency and reducing the false detection rate.

[0046] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as above in the form of preferred embodiments, it is not intended to limit the present invention. Any technical personnel in the field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
