Description

Technical Field

[0001] This invention relates to a high-voltage testing device for laminated insulated flat wires, and more particularly to a novel automatic high-voltage testing device for laminated insulated flat wires. Background Technology

[0002] Flexible Flat Cable (FFC) with laminated insulation is currently manufactured with the insulation cut into segments, resulting in discontinuous insulation. Therefore, high-voltage spark testing is not performed during production. According to current US UL758 standards and related requirements, factories are required to conduct subsequent high-voltage testing on samples. Currently, factories perform testing manually. The insulation is wrapped in aluminum foil, pressed firmly with a metal plate, and the metal conductor is clamped. Voltage is applied manually to one end of the conductor and the other end to the aluminum foil to complete the test of one sample. According to the required sampling plan, large batches require thousands of samples. This method requires a large amount of manpower and may result in insufficient testing time or errors such as poor contact between the insulation surfaces. New automated high-voltage testing machines can replace manual operation, increasing testing speed, reducing fatigue, and avoiding errors caused by manual operation.

[0003] A high-voltage testing device for GIS insulating components, disclosed in CN104865507A, includes a transformer, a sulfur hexafluoride (SF6) insulating gas cylinder, a voltage divider, and several test units. The transformer is connected to the SF6 insulating gas cylinder via an oil-gas bushing, and the voltage divider is also connected to the SF6 insulating gas cylinder via a pipeline. Each test unit is connected to the SF6 insulating gas cylinder and includes a test tank. A basin-shaped casting body is provided at the connection between the test tank and the SF6 insulating gas cylinder. The basin-shaped casting body is bolted to the port of the test tank to isolate the gas between the second connecting pipeline and the test tank. A conductor is provided on the basin-shaped casting body to connect the busbar to the insulating component under test. Several cylindrical rollers are provided inside the test tank, with the central axis of the rollers perpendicular to the central axis of the test tank. This device occupies little space, is simple to operate, and has low cost. Summary of the Invention

[0026] The above technical solution has the following advantages or beneficial effects:

[0027] 1. This invention uses a rotating adjustment handwheel to drive the drive wheel to rotate. The drive wheel, in turn, drives the transmission wheel via a transmission belt. This causes the drive wheel and the transmission wheel to move synchronously, moving the ball screw connected to them. This causes the two connecting plates to move synchronously to the left or right, which in turn moves the adjustment plate fixed to the two connecting plates. This changes the distance between the adjustment plate and the fabric transfer frame, making it easier to adjust the distance of the conductive fabric so that the device can adapt to samples of various lengths.

[0028] 2. This invention operates by controlling a drive motor to rotate a feeding wheel on a feeding frame, which in turn moves the conductive cloth inside the feeding wheel. As the conductive cloth rotates and retracts within the feeding wheel, new conductive cloth passes through an adjustment plate and a transfer frame, allowing for convenient replacement of the conductive cloth between the adjustment plate and the transfer frame. This prevents inconvenience in replacing the conductive cloth when it is damaged or malfunctions.

[0029] 3. By adjusting the synchronous operation between the upper fabric receiving mechanism and the upper fabric feeding mechanism, and between the lower fabric receiving mechanism and the lower fabric feeding mechanism, the present invention can tension the conductive cloth between the adjusting plate and the fabric transfer frame, so that the conductive cloth is flat and attached to the insulating surface of the test sample, thereby enhancing the detection effect.

[0030] 4. The present invention allows for the placement of samples to be tested, qualified samples, and unqualified samples in the first product box, the second product box, and the third product box, respectively, which facilitates the recycling of qualified and unqualified samples.

[0031] 5. This invention uses a drive wheel and a transmission wheel in conjunction with a transmission belt to work, so that the drive wheel and the transmission wheel can drive the adjustment plate to move synchronously, thereby achieving the effect of synchronously adjusting the distance between the adjustment plate and the fabric frame.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] Reference Figures 1-6 One embodiment of the present invention provides a novel automatic high-voltage testing device for laminated insulated flat wires, comprising: a body 1, an adjustment structure 2 connected to the body 1, one side of the adjustment structure 2 connected to a cloth-laying structure 3, a feeding structure 4 connected to the body 1, a placement rack 5 disposed below the feeding structure 4, and the adjustment structure 2 connected to one side of a clamping cylinder 6. The adjustment structure 2 further includes: a mounting box 201, fixed to the body 1 by screws; two ball screws 202, fixed inside the mounting box 201 by screws; and two connecting plates 203, one side connected to the ball screws 202. Mechanism 204 is fixedly connected to one side of ball screw 202 by screws. By rotating the adjusting handwheel 205, the driving wheel 206 is driven to rotate. The driving wheel 206 then drives the transmission wheel 208 through the transmission belt 207. This causes the driving wheel 206 and the transmission wheel 208 to move the ball screw 202 connected to them synchronously. This causes the two connecting plates 203 to move synchronously to the left or right, which in turn causes the adjusting plate 37 fixed to the two connecting plates 203 to move. This changes the distance between the adjusting plate 37 and the fabric transfer frame 36, making it easy to adjust the distance of the conductive fabric so that the equipment can adapt to samples of different lengths.

[0043] Furthermore, the fabric feeding structure 3 is fixed to the machine body 1 with screws. The fabric feeding structure 3 also includes: an upper fabric taking-up mechanism 31, fixed to the machine body 1 on one side; an upper fabric feeding mechanism 32, connected above the mounting box 201; a lower fabric taking-up mechanism 33, located below the upper fabric taking-up mechanism 31, fixed to the machine body 1 on one side; a lower fabric feeding mechanism 34, located below the upper fabric feeding mechanism 32, fixed to the machine body 1 on one side; and a fabric guide frame 35, connected to the machine body 1 on one side. Two fabric guide frames 35 are provided, and the fabric enters the corresponding... After passing through the guide frame 35, the fabric enters the upper take-up mechanism 31 and the lower take-up mechanism 33. The drive motor 310 is controlled to work, driving the feed wheel 311 to rotate on the feed frame 312, so that the feed wheel 311 drives the conductive fabric inside to move. As the conductive fabric rotates and is retracted in the feed wheel 311, the new conductive fabric passes through the adjustment plate 37 and the transfer frame 36, so that it is convenient to replace the conductive fabric between the adjustment plate 37 and the transfer frame 36. This prevents the inconvenience of replacing the conductive fabric when it is damaged or fails.

[0044] Furthermore, the feeding structure 4 is fixed to the surface of the machine body 1. The machine body 1 also includes: a slide rail 41 fixed to the surface of the machine body 1; a first feeding cylinder 42 connected above the slide rail 41; and a second feeding cylinder 43 connected above the slide rail 41. The slide rail 41 facilitates the sliding of the first feeding cylinder 42 and the second feeding cylinder 43. Both the first feeding cylinder 42 and the second feeding cylinder 43 have the ability to detect whether the sample is qualified, which facilitates the transportation of the sample.

[0045] Furthermore, the first product box 7, the second product box 8, and the third product box 9 are connected above the placement rack 5; the first product box 7, the second product box 8, and the third product box 9 can be used to place the sample to be tested, the qualified sample, and the unqualified sample, respectively, which makes it convenient to recycle the qualified sample and the unqualified sample.

[0046] Furthermore, the clamping cylinder 6 is located between the upper fabric feeding mechanism 32 and the lower fabric feeding mechanism 34, and a high-voltage electric release clamp 10 is fixed on one side of the clamping cylinder 6; the sample is tested through the high-voltage electric release clamp 10.

[0047] Furthermore, the rotating mechanism 204 also includes an adjusting handwheel 205, a drive wheel 206, a transmission belt 207, and a transmission wheel 208. The adjusting handwheel 205 is fixed to one end of the drive wheel 206. Both the drive wheel 206 and the transmission wheel 208 are connected to one end of the ball screw 202. The transmission belt 207 is connected between the drive wheel 206 and the transmission wheel 208. The drive wheel 206 and the transmission wheel 208 work in conjunction with the transmission belt 207, so that the drive wheel 206 and the transmission wheel 208 can synchronously drive the adjusting plate 37 to move, thereby achieving the effect of synchronously adjusting the distance between the adjusting plate 37 and the fabric transfer frame 36.

[0048] Furthermore, the guide frame 35 also includes a transfer frame 36 and an adjustment plate 37. The transfer frame 36 is connected to the machine body 1, and one end of the adjustment plate 37 is fixed to the connecting plate 203. By adjusting the synchronous operation between the upper take-up mechanism 31 and the upper feed mechanism 32 and between the lower take-up mechanism 33 and the lower feed mechanism 34, the conductive cloth between the adjustment plate 37 and the transfer frame 36 can be tensioned, so that the conductive cloth is flatly attached to the insulating surface of the test sample, thereby enhancing the detection effect.

[0049] Furthermore, an upper conductive cloth 38 and a lower conductive cloth 39 are respectively provided between the upper fabric receiving mechanism 31 and the upper fabric feeding mechanism 32, and between the lower fabric receiving mechanism 33 and the lower fabric feeding mechanism 34. Two guide frames 35 are provided. The upper fabric receiving mechanism 31, the upper fabric feeding mechanism 32, the lower fabric receiving mechanism 33, and the lower fabric feeding mechanism 34 have the same structure. The upper conductive cloth 38 of the upper fabric receiving mechanism 31 and the upper fabric feeding mechanism 32 can be raised and lowered on the machine body 1.

[0050] Furthermore, the upper feeding mechanism 32 also includes a drive motor 310, a feeding wheel 311, and a feeding frame 312. One end of the drive motor 310 is connected to the feeding wheel 311, the lower part of the feeding wheel 311 is rotatably connected to the feeding frame 312, and the lower part of the feeding frame 312 is fixedly connected to the machine body 1. The drive motor 310 drives the feeding wheel 311 to rotate.

[0051] Furthermore, an operation screen 11 and a control box 12 are provided on the top of the machine body 1; by adjusting the movement position displayed on the display on the handwheel 205, this number is input into the intelligent operation screen 11. At this time, the operation screen 11 automatically calculates the movement position of the first feeding cylinder 42 and the second feeding cylinder 43 controlled by the control box 12.

[0052] Working principle: When the equipment is working, the sample to be tested is placed in the first product box 7. The first feeding cylinder 42 automatically sucks the sample from the first product box 7 to the lower conductive cloth 39 between the adjusting plate 37 and the transfer frame 36. The metal end of the sample is clamped by the clamping cylinder 6 as one end of the high-voltage electrode. At the same time, the machine body 1 moves the upper conductive cloth 38 downward, and together with the lower conductive cloth 39, clamps the wire insulation layer as the other end of the high-voltage electrode. The high-voltage discharge fixture 10 releases the high voltage, completing the test. Then, the test results distinguish between good and defective products. The second feeding cylinder 43 puts the samples with good test results into the second product box 8 and the samples with defective test results into the third product box 9. Rotating the adjustment handwheel 205 drives the drive wheel 206 to rotate. The drive wheel 206, through the transmission belt 207, drives the transmission wheel 208, causing the drive wheel 206 and transmission wheel 208 to synchronously drive the ball screw 202 connected to them to move. This causes the two connecting plates 203 to move synchronously to the left or right, thereby moving the adjustment plate 37 fixed to the two connecting plates 203. This changes the distance between the adjustment plate 37 and the fabric transfer frame 36, making it easy to adjust the distance of the conductive cloth so that the equipment can adapt to samples of various lengths. By controlling the drive motor 310 to work, the feed wheel 311 rotates on the feed frame 312, causing the feed wheel 311 to move the conductive cloth inside it. As the conductive cloth rotates and retracts within the feed wheel 311, new conductive cloth passes through the adjustment plate 37 and the fabric transfer frame 36, making it easy to replace the conductive cloth between the adjustment plate 37 and the fabric transfer frame 36. This prevents inconvenience in replacing the conductive cloth when it is damaged or malfunctions.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
