Technical Field

[0002] Insulating rubber pads are also called insulating blankets, insulating pads, insulating rubber sheets, insulating rubber sheets, insulating rubber pads, insulating floor glue, insulating rubber skin, insulating gaskets, etc. They are rubber pads with large volume resistivity and resistance to electrical breakdown. They are used as insulating materials for countertops or floor coverings in work places such as power distribution. After production, insulating pads need to be tested for withstand voltage to determine whether the product is qualified.
[0003] When testing the insulating pad, if the appearance of the insulating pad is intact, lay a wet cloth, metal foil or other material on the insulating pad to be tested, and raise the test voltage to the specified voltage value by placing a energized metal block on the material. If the insulating pad product is qualified, there should be no flashover or breakdown in the test, and there should be no burning or obvious heating in all parts after the test.
[0004] When the existing detection device is in use, due to the different sizes and specifications of insulation, it is necessary to change the position of the laid conductive material on the insulation pad for detection. Such detection efficiency is low and is not suitable for batch detection. Utility Model Content
[0005] The technical solution of the utility model aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the purpose of the utility model is to provide a voltage resistance detection device for insulating pads to solve the problems of low detection efficiency and unsuitability for batch detection raised by the above-mentioned background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a withstand voltage detection device for an insulating pad, comprising a workbench, a support plate is symmetrically installed at the bottom of the workbench, and a rectangular groove is opened inside one end of the workbench, two groups of rotating shafts are symmetrically rotatably connected inside the rectangular groove, rubber rollers are fixedly installed on the outer walls of the two groups of rotating shafts, aluminum foil is fixedly installed on the outer wall of one group of rubber rollers, a motor is fixedly installed on the side wall of the workbench, the output end of the motor is fixedly connected to one end of one group of rotating shafts, a limiting mechanism is arranged on the top of the workbench, and a voltage output mechanism located at the bottom of the rubber roller is arranged on the outer wall of the support plate.
[0007] Preferably, one end of the two groups of rotating shafts passes through the outer wall of the workbench and is sleeved with a transmission belt.
[0008] Preferably, the limiting mechanism comprises two sets of fixing plates symmetrically fixedly arranged on the top of the workbench, a bidirectional screw is rotatably connected between the upper ends of the two sets of fixing plates, and the outer wall of the bidirectional screw is symmetrically sleeved with two sets of limiting plates which are threadably matched therewith.
[0009] Preferably, the two groups of limit plates are located on the top of the two groups of rubber rollers, and a limit rod slidably matched with the two groups of limit plates is fixedly arranged between the upper ends of the two groups of fixed plates.
[0010] Preferably, the voltage output mechanism includes a voltage regulating device fixedly mounted on the outer wall of a group of support plates, and an insulating bracket is fixedly mounted on the outer wall of the support plate, the end of the insulating bracket is rotatably connected to a conductive shaft, a conductive roller is fixedly provided on the outer wall of the conductive shaft, and the end of the conductive shaft is rotatably connected to a conductive column.
[0011] Preferably, the voltage regulating device is electrically connected to the conductive column, and the conductive roller is in contact with the aluminum foil on the outer wall of a group of rubber rollers.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] When the utility model detects the insulating pad, the motor is started to make the two groups of rubber rollers rotate synchronously, the aluminum foil on the outer wall of one group of rubber rollers is always in contact with the conductive roller, and the conductive roller can be rotated synchronously when the rubber roller rotates, and the aluminum foil on the outer wall of the rubber roller is always charged. At this time, a batch of insulating pads can be placed on the other group of non-charged rubber rollers for transmission. When the insulating pad is transmitted to the aluminum foil on the outer wall of the other group of rubber rollers, the position where the insulating pad contacts the aluminum foil can be subjected to a withstand voltage test. When the insulating pad is completely transmitted through the aluminum foil, the withstand voltage test of the insulating pad can be completed. If burning or heating occurs on the surface of the insulating pad, the insulation of the insulating pad is poor. Through this detection method, not only the withstand voltage detection efficiency of the insulating pad is improved, but also the detection of the insulating pad can be made more comprehensive, and batch detection can be performed.

[0021] One end of the two sets of rotating shafts 4 passes through the outer wall of the workbench 1 and is sleeved with a transmission belt 8. Under the action of the transmission belt 8, the two sets of rotating shafts 4 can rotate synchronously.
[0022] The limiting mechanism includes two groups of fixed plates 9 symmetrically fixed on the top of the workbench 1, and a bidirectional screw rod 10 is rotatably connected between the upper ends of the two groups of fixed plates 9. The outer wall of the bidirectional screw rod 10 is symmetrically sleeved with two groups of limiting plates 11 that cooperate with its thread. The bidirectional screw rod 10 is rotated to make the two groups of limiting plates 11 move toward each other, and the spacing between the two groups of limiting plates 11 is adjusted according to the detected size of the insulating pad for limiting.
[0023] The two groups of limit plates 11 are located on the top of the two groups of rubber rollers 5, and a limit rod 12 slidably matched with the two groups of limit plates 11 is fixedly arranged between the upper ends of the two groups of fixing plates 9, and the two groups of limit plates 11 slide on the limit rod 12 for limiting.
[0024] The voltage output mechanism includes a voltage regulating device 13 fixedly mounted on the outer wall of a group of support plates 2, and an insulating bracket 14 is fixedly mounted on the outer wall of the support plate 2, the end of the insulating bracket 14 is rotatably connected to a conductive shaft 15, a conductive roller 16 is fixedly arranged on the outer wall of the conductive shaft 15, and the end of the conductive shaft 15 is rotatably connected to a conductive column 17, and the voltage regulating device 13 is adjusted to the test voltage of the insulating pad so that the conductive column 17 reaches the test voltage, and the conductive shaft 15 and the conductive roller 16 are both charged.
[0025] The voltage regulating device 13 is electrically connected to the conductive column 17, and the conductive roller 16 is in contact with the aluminum foil 6 on the outer wall of a group of rubber rollers 5. The voltage of the conductive column 17 is controlled by the voltage regulating device 13, and the conductive roller 16 is in contact with the aluminum foil 6 so that the aluminum foil 6 is always charged.
[0026] Working principle: When using the withstand voltage detection device for insulating pads, first, start the motor 7, the motor 7 drives a set of rotating shafts 4 to rotate, under the action of the transmission belt 8, the two sets of rotating shafts 4 rotate synchronously, so that the two sets of rubber rollers 5 rotate synchronously, and at the same time adjust the voltage regulating device 13 to the test voltage of the insulating pad, so that the conductive column 17 reaches the test voltage, and the conductive shaft 15 and the conductive roller 16 are both charged, and the aluminum foil 6 on the outer wall of a set of rubber rollers 5 always sticks to the conductive roller 16, and when the rubber roller 5 rotates, the conductive roller 16 can rotate synchronously, so that the outer wall of the rubber roller 5 of the group The aluminum foil 6 is always charged.
