Description

Technical Field

[0001] This invention relates to the field of plug testing device technology, and specifically to an automatic testing device for plug insulation performance. Background Technology

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

[0003] like Figure 8 Existing plug insulation performance testing devices employ two opposing cylinders. Each cylinder's piston rod has an insulation test block at its end. This block contains an internal conductor encased in insulating material. When the two blocks clamp the plug, the insulation performance at the plug connection is determined by detecting the leakage current at the point of breakdown. However, these devices require manual insertion and removal of the plug, resulting in low testing efficiency and a high false positive rate. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic detection device for plug insulation performance, which can improve detection efficiency and reduce false detection rate.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic plug insulation performance testing device includes a cabinet with a chain transmission mechanism inside. The chain of the chain transmission mechanism is divided into an upper chain segment and a lower chain segment. Specific links of the chain are fixedly connected to a power supply plug carrier and an appliance plug carrier. The power supply plug carrier and the appliance plug carrier are alternately arranged and evenly distributed along the chain. One end of the appliance plug on the appliance plug carrier is temporarily inserted, and one end of the power supply plug on the power supply plug carrier is also temporarily inserted. An opening is provided on the upper right side of the cabinet. A slide is provided on the top edge of the right side wall of the cabinet. The surface of the slide is slightly lower than the height of the insertion holes of the power supply plug carrier and the appliance plug carrier on the upper chain segment. A feeding mechanism is provided on the front side of the chain transmission mechanism. The feeding mechanism has a longitudinal frame, and a longitudinal... The guide rail is slidably connected to a longitudinal slide block. The longitudinal slide block is fixedly connected to two connecting seats. The bottom wall of one connecting seat is slidably connected to a transverse slide block for a power plug, and the bottom wall of the other connecting seat is slidably connected to a transverse slide block for an electrical plug. The transverse slide block for the power plug is fixedly connected to a power plug clamp, and the transverse slide block for the electrical plug is fixedly connected to an electrical plug clamp. The slide table has a recess, and a lower cylinder is located in the recess. The piston rod of the lower cylinder is fixedly connected to a lower insulation test soft block. A testing mechanism is located on the rear side of the chain transmission mechanism. The testing mechanism has an upper cylinder, and the piston rod of the upper cylinder is fixedly connected to an upper insulation test soft block. The upper insulation test soft block and the lower insulation test soft block can abut against each other to simultaneously clamp the electrical plug and the power plug of the same wire.

[0007] Specifically, the chain transmission mechanism is equipped with a motor and a reducer. The output shaft of the reducer is equipped with a sprocket, and the sprocket is connected to a chain.

[0008] Specifically, the connector is equipped with a power plug insertion / removal cylinder, and the piston rod of the power plug insertion / removal cylinder is fixedly connected to the transverse slide of the power plug.

[0009] Specifically, the connector is equipped with an appliance plug insertion / removal cylinder, and the piston rod of the appliance plug insertion / removal cylinder is fixedly connected to the transverse slide of the appliance plug.

[0011] Specifically, the longitudinal frame is equipped with a moving motor, which is connected to the longitudinal lead screw via a belt.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The automatic plug insulation performance testing device of the present invention utilizes pairs of power plug carriers and appliance plug carriers to carry the wire to be tested, and drives multiple pairs of socket carriers to move intermittently via a chain. When the wire to be tested moves to the testing station, the lower insulation testing block and the upper insulation testing block clamp the wire connection of the power plug and appliance plug of the wire to be tested, thereby quickly testing the insulation performance of the joints at both ends of the wire to be tested. The above process requires no manual intervention, thereby improving testing efficiency and reducing the false test rate. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] See Figures 1 to 7 An automatic plug insulation performance testing device includes a cabinet, within which a chain transmission mechanism 1 is installed. The chain of the chain transmission mechanism 1 is divided into an upper chain segment and a lower chain segment. Specific links of the chain are fixedly connected to a power plug carrier 11 and an appliance plug carrier 12. The power plug carrier 11 and the appliance plug carrier 12 are alternately arranged and evenly distributed along the chain. Figures 1 to 3 One end of the appliance plug of the appliance plug carrier 12 supplying wire 5 (shown in dashed line) is temporarily inserted, and one end of the power plug of the power supply plug carrier 11 supplying wire 5 is temporarily inserted.

[0032] An opening is provided on the upper right side of the cabinet. A slide 2 is provided on the top edge of the right side wall of the cabinet. The surface of the slide 2 is slightly lower than the height of the sockets of the power supply plug carrier 11 and the appliance plug carrier 12 on the upper chain section (see...). Figure 2 The chain conveyor mechanism 1 has a feeding mechanism 3 on its front side. The feeding mechanism 3 has a longitudinal frame 31, and a longitudinal guide rail 32 is fixedly connected to the longitudinal frame 31. A longitudinal slide block 33 is slidably connected to the longitudinal guide rail 32. Two connecting seats 331 are fixedly connected to the longitudinal slide block 33. The bottom wall of one connecting seat 331 is slidably connected to a power plug transverse slide block 34, and the bottom wall of the other connecting seat 331 is slidably connected to a power plug transverse slide block 35. A power plug clamp 341 is fixedly connected to the power plug transverse slide block 34. A power plug clamp 351 is fixedly connected to the power plug transverse slide block 35.

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

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

[0035] Specifically, see Figure 5 The connector 331 is equipped with a power plug insertion / removal cylinder 342, and the piston rod of the power plug insertion / removal cylinder 342 is fixedly connected to the power plug transverse slide 34.

[0036] Specifically, see Figure 5 The connector 331 is equipped with an appliance plug insertion / removal cylinder 352, and the piston rod of the appliance plug insertion / removal cylinder 352 is fixedly connected to the appliance plug transverse slide 35.

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

[0038] Specifically, the longitudinal frame 31 is equipped with a moving motor 13, which is connected to the longitudinal lead screw 36 via a belt.

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

[0040] The automatic plug insulation performance testing device has a wire transfer device (not shown in the figure) on its rear side. The wire transfer device has multiple pairs of transfer fixtures (not shown in the figure). The transfer fixtures have power plug sockets and appliance plug sockets. The wire to be tested is 5 (reference). Figure 1 Insert the two ends of the wire 5 into the power plug socket and the appliance plug socket respectively, so that the wire 5 to be tested can move forward with the transfer fixture.

[0041] When the transfer fixture moves to the front, the power plug clamp 341 and the appliance plug clamp 351 both move backward and clamp the two ends of the wire 5 to be tested respectively. Then, the power plug insertion / removal cylinder 342 and the appliance plug insertion / removal cylinder 352 both extend outward, thereby pulling out the two ends of the wire 5 to be tested.

[0042] Subsequently, both the power plug gripper 341 and the appliance plug gripper 351 move forward to a suitable position, aligning both ends of the wire to be tested 5 with the chain loading position. Figure 1The power plug carrier 11 and the appliance plug carrier 12 are located at point B. After alignment, the power plug insertion / removal cylinder 342 and the appliance plug insertion / removal cylinder 352 retract, thereby inserting the power plug of the wire to be tested 5 into the power plug carrier 11 and inserting the appliance plug of the wire to be tested 5 into the appliance plug carrier 12.

[0043] Subsequently, the forward movement of the upper chain segment corresponds to the distance of a pair of sockets (a power plug carrier 11 and an appliance plug carrier 12), causing the empty pair of sockets (as above) to move to the chain loading position. Figure 1 At point B), the multiple test wires 5 connected to the other multiple pairs of sockets move forward along the slide table 2. When a test wire 5 moves between the lower insulation test soft block 221 and the upper insulation test soft block 411 (e.g., at point B), the test wires 5 move forward along the slide table 2. Figure 2 As shown, the chain stops. The lower insulation test block 221 and the upper insulation test block 411 approach each other and clamp the wire connection of the power supply plug and the appliance plug of the wire under test 5. Both the lower insulation test block 221 and the upper insulation test block 411 are energized. If the circuit formed by the lower insulation test block 221 and the upper insulation test block 411 is conductive, that is, the wire connection of the power supply plug and the appliance plug of the wire under test 5 is broken down, and the insulation performance fails to meet the standard.

[0044] After the test is completed, the wire 5 under test continues to move forward with the chain. The material handling mechanism (not shown in the figure) located at the front of the present invention will take away the wire 5 at the front end of the chain and transfer it to the next testing device.

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

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
