In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
Referring to fig. 1, an embodiment of the present application provides an insulation boot voltage withstand test system 10, including: a withstand voltage tester 110, a steel ball conveying device 120 and a conveying device 130. The conveyor 130 is located between the preparation station and the testing station 20. A withstand voltage tester 110 is located at the test station 20. The withstanding voltage tester 110 includes a testing terminal 111 and a receiving terminal 112. The test terminal 111 can be inserted into the insulating boot 30 and supplies a high voltage, and the receiving terminal 112 is provided outside the insulating boot 30 for receiving a test signal. The conveyor 130 is capable of transferring the insulating shoe 30 to be tested from the preparation station to the receiving end 112 of the testing station 20. The steel ball conveying device 120 is provided with an output end and an input end, and the steel ball conveying device 120 is used for conveying steel balls from the input end to the output end. The output end is located at the preparation station and is opposite to the insulating boot 30 to be tested, which is placed on the preparation station, and the output end can throw the steel balls into the insulating boot 30 to be tested. The input end is located at the test station 20 and opposite to the insulating shoe 30 placed on the test station 20, and the input end can take out the steel balls in the tested insulating shoe 30 located on the test station 20.
The above-described aspect provides a voltage resistance test system of the insulating boot 30 in which the transfer device 130 is disposed between the preparation station and the test station 20. The steel ball conveying device 120 is provided with an output end and an input end, wherein the output end is positioned at the preparation station and is opposite to the insulating boot 30 to be tested, which is positioned on the preparation station, and the output end can throw the steel balls into the insulating boot 30 to be tested; the input end is located at the test station 20 and opposite to the insulating shoe 30 placed on the test station 20, and the input end is capable of taking out the steel balls in the tested insulating shoe 30 located on the test station 20. In this way, the conveying device 130 can be used to automatically transfer the insulating shoe 30 which is filled with steel balls and is to be tested from the preparation station to the testing station 20, and the process does not need to manually transfer the insulating shoe 30, so that the labor intensity can be reduced. Meanwhile, since the withstand voltage tester 110 is located at the testing station 20, the testing end 111 of the withstand voltage tester 110 can be inserted into the insulating boot 30 and provide a high voltage, and the receiving end 112 of the withstand voltage tester 110 is located outside the insulating boot 30 and can receive a testing signal, the testing of the insulating property of the insulating boot 30 can be completed at the testing station 20.

Specifically, the testing end 111 of the pressure tester 110 includes a testing electrode, and the receiving end 112 of the pressure tester 110 includes a soaked sponge and a milliammeter connected to the sponge. When a voltage withstand test is carried out, the insulating boot 30 with the steel balls is placed on the sponge, the test electrode is inserted into the insulating boot 30, higher voltage is applied to the test electrode, and the insulating performance of the insulating boot 30 is judged by observing the numerical change condition of the milliammeter. If the current measured by the milliammeter is less than or equal to a prescribed value, it indicates that the insulating property of the insulating shoe 30 is good.
It should be noted that, the method for testing the voltage resistance of the insulating boot 30 by using steel balls belongs to the prior art, and the specific test principle and process are not described herein again.
Referring to fig. 1, in an embodiment based on the above-mentioned embodiments, the ball conveying device 120 includes a recycling bin 121, a position switching assembly 122, a slide rail 123, and an electromagnet 124. The recycling box 121 is provided with an opening, the recycling box 121 is connected with a position switching component 122, and the position switching component 122 enables the recycling box 121 to have a first position and a second position. When the recovery cassette 121 is in the first position, the recovery cassette 121 is between the test station 20 and the preparation station, and an opening of the recovery cassette 121 can face the electromagnet 124. When the recovery box 121 is located at the second position, the recovery box 121 is located above the preparation station, and the opening of the recovery box 121 can communicate with the shoe mouth of the insulating shoe 30 placed at the preparation station. The test station 20 and the first position of the recovery box 121 are arranged at intervals along the guiding direction of the slide rail 123. The electromagnet 124 is slidably disposed on the slide rail 123, and the electromagnet 124 can be switched between the test station 20 and the first position. The end of the slide rail 123 corresponding to the test station 20 is the input end of the steel ball conveying device 120.
Specifically, in the present embodiment, when the recovery box 121 is located at the first position, the recovery box 121 and the test station 20 are disposed at an interval in the guide direction of the guide rail, and the recovery box 121 is interposed between the test station 20 and the preparation station. The electromagnet 124 moves on the slide rail 123, after the insulation test is performed on the insulating boot 30 placed on the test station 20 by the voltage tester 110, the test end 111 of the voltage tester 110 is taken out of the insulating boot 30, the electromagnet 124 moves to the position above the tested insulating boot 30, and at this time, the electromagnet 124 is powered on to take out the steel balls in the insulating boot 30 and adsorb the steel balls on the electromagnet 124. Subsequently, the electromagnet 124 is moved to move the electromagnet 124 to the upper side of the first position, and the power is cut off to drop the steel ball from the electromagnet 124 into the recovery box 121 at the first position. Subsequently, the recovery box 121 is moved from the first position to the second position by the position switching member 122. Since the opening of the recovery box 121 can communicate with the boot opening of the insulation boot 30 placed at the preparation station when the recovery box 121 is located at the second position, the steel balls in the recovery box 121 can be thrown into a new insulation boot 30 to be tested again. The automatic recovery of steel balls can be realized in the whole process, and the work efficiency is improved while the labor is saved.
Alternatively, in another embodiment, the ball transport device 120 includes only the slide rail 123 and the electromagnet 124. Two ends of the slide rail 123 are respectively arranged at the testing station 20 and the preparation station, and the electromagnet 124 is slidably arranged on the slide rail 123 along the guiding direction of the slide rail 123, so that the electromagnet 124 can be switched between the testing station 20 and the preparation station. Specifically, both ends of the slide rail 123 are located above the insulating shoe 30 at the test station 20 and the insulating shoe 30 at the preparation station, respectively, in the longitudinal direction. When the electromagnet 124 is located at the testing station 20, the electromagnet 124 is powered on to suck the steel balls in the insulating shoe 30 located at the testing station, then the electromagnet 124 carries the steel balls to move to the preparation station, and the electromagnet 124 is powered off to throw the steel balls into the insulating shoe 30 located at the preparation station.
Further, in one embodiment, position switch assembly 122 includes a fixed pulley 1221, a cable 1222, and a flipping mechanism 1223. Specifically, the turnover mechanism 1223 is located above the preparation station in the longitudinal direction. The rope 1222 is wound around the fixed pulley 1221. One end of the pulling rope 1222 is connected to the recovery box 121, and the other end of the pulling rope 1222 is connected to the turnover mechanism 1223. The turnover mechanism 1223 is used to recover or release the pulling rope 1222 so that the recovery box 121 has a first position and a second position. When the recovery cassette 121 is located at the second position, the recovery cassette 121 is placed on the turnover mechanism 1223. In this way, the specific position of the recovery box 121 can be changed by the cooperation of the fixed pulley 1221, the rope 1222 and the turnover mechanism 1223, and the recovery box 121 can be switched between the first position and the second position to complete the corresponding position.
As shown in fig. 1, since one end of the pulling rope 1222 connected to the recycling box 121 is in a vertical state under the action of gravity, in order to prevent the recycling box 121 from being switched from the first position to the second position, the recycling box 121 is turned at the fixed pulley 1221 to cause the steel balls in the recycling box 121 to fall from the opening, optionally, a baffle is disposed on the recycling box 121, the baffle is covered on the opening of the recycling box, and the baffle is hinged to a wall surface of the recycling box 121, when the recycling box 121 is in the first position, the baffle rotates to expose the opening, so that the steel balls on the electromagnet 124 can enter the recycling box 121 from the opening. When the recycling box 121 moves, the baffle plate rotates relative to the side wall of the recycling box 121 so as to cover the recycling box 121 at the opening, and thus, the steel balls can be prevented from falling from the opening when the moving direction of the recycling box 121 is changed.
Optionally, in another embodiment, the position switching assembly 122 includes a robot arm and a robotic arm. The manipulator is arranged on the manipulator arm, and the manipulator can grab between the first position and the preparation station through swinging of the manipulator arm.
Specifically, the second position of the recovery box 121 is at the preparation station and above the storage mechanism 140, and the first rotating shaft 12231 rotates to recover the string 1222 during switching of the recovery box 121 from the first position to the second position, so that the recovery box 121 can move from the first position to the second position along the moving path of the string 1222.
To ensure that the recovery box 121 can be switched from the second position to the first position, a reset mechanism (not shown in the figure) is optionally hung on the recovery box 121. The resetting mechanism comprises a connecting rope. One end of the connecting rope is connected with the recovery box 121, and the other end of the connecting rope is used for holding or tying a heavy object. The mass of the weight should be greater than the sum of the mass of the recovery box 121 and the mass of the steel balls placed in the recovery box 121. The length of the connecting rope is greater than the length of the path of movement of the recovery box 121 when the recovery box is switched from the first position to the second position. Specifically, when it is necessary to transfer the recovery box 121 from the second position to the first position, the first rotating shaft 12231 releases the pulling rope 1222, and at this time, the connecting rope is held by hand and pulled downward. Alternatively, when the end of the connection string away from the recovery box 121 is tied to a weight, if it is necessary to transfer the recovery box 121 from the second position to the first position, the first rotation shaft 12231 may be made to release the string 1222, and the recovery box 121 may be automatically transferred from the second position to the first position by the gravity of the weight.
Referring to fig. 1, in addition to the above-mentioned embodiment, in an embodiment, the ball conveyor 120 further includes a storage mechanism 140. The storage mechanism 140 in the longitudinal direction is interposed between the turnover mechanism 1223 and the insulating shoe 30 at the preparation station. The turnover mechanism 1223 includes a first rotating shaft 12231, a second rotating shaft 12232 and a turnover frame 12233, the first rotating shaft 12231 is disposed in the turnover frame 12233, and one end of the pulling rope 1222 far from the recovery box 121 is connected with the first rotating shaft 12231 and can be wound on the first rotating shaft 12231, the turnover frame 12233 is disposed on the second rotating shaft 12232, the turnover frame 12233 can rotate around the central axis of the second rotating shaft 12232, so that when the recovery box 121 is located at the second position, the opening of the recovery box 121 can face downward and is opposite to and communicated with the inlet of the storage mechanism 140. In this way, the flip frame 12233 can change the opening orientation of the recovery box 121 by the second rotating shaft 12232. When the recycling bin 121 is opened toward and opposite to and in communication with the inlet of the storage mechanism 140, the steel balls in the recycling bin 121 can fall into the storage mechanism 140, and the steel balls are redistributed into each of the insulating shoes 30 to be tested by the storage mechanism 140.
Further, in one embodiment, the storage mechanism 140 includes a conduit 141 and an on-off valve 142. The switch valve 142 is disposed on the pipe 141, an outlet of the pipe 141 is located above the insulating shoe 30 in the longitudinal direction, and the outlet of the pipe 141 can communicate with a shoe opening of the insulating shoe 30, and the outlet of the pipe 141 is an output end of the steel ball conveying device 120. In this way, the steel balls can be stored in the pipeline 141, and when the steel balls need to be thrown into each insulation shoe 30 to be tested, the switch valve 142 is opened.
Note that the phrase "the outlet of the duct 141 can communicate with the shoe opening of the insulating shoe 30" includes a case where the outlet of the duct 141 can directly communicate with the shoe opening of the insulating shoe 30, that is, the end of the duct 141 provided with the outlet can be connected to the insulating shoe 30, and the outlet of the duct 141 communicates with the shoe opening of the insulating shoe 30. Alternatively, the end of the duct 141 having the outlet is spaced apart from the insulating boot 30, but in the case where the outlet of the duct 141 is opposite to the boot mouth of the insulating boot 30, the steel balls in the duct 141 can also flow to the boot mouth through the outlet of the duct 141.
In order to prevent the steel balls from falling off during the process of transferring the steel balls from the recycling bin 121 to the duct 141, the duct 141 is further in a funnel shape, and the diameter of the inlet of the duct 141 is larger than that of the outlet of the duct 141. Thus, the large-diameter pipeline 141 inlet can prevent the steel balls from falling off in the replacement process, and the small-diameter pipeline 141 outlet can accurately control the quantity of the steel balls thrown into each insulating boot 30 to be tested.
Further, an infrared sensor is disposed on the pipe 141, and the infrared sensor is used for positioning the boot opening of the insulating boot 30 and is electrically connected to the switch valve 142. When the infrared ray detects the boot opening, the switch valve 142 on the pipeline 141 is opened, and the steel ball flows from the outlet of the pipeline 141 into the insulating boot 30.
In addition to the above embodiments, in an embodiment, a telescopic driving member (not shown) is slidably disposed on the sliding rail 123. The telescopic driving piece comprises a fixed end and a telescopic end which are connected.

When the suction is completed, the telescopic end is directed in the opposite direction to withdraw from the inside of the insulating boot 30.

The conveyor belt 131 and the gripper 132 are both located between the preparation station and the testing station 20. The conveying direction of the conveyor belt 131 is from the preparation station toward the test station 20. A plurality of the insulation shoes 30 to be tested may be sequentially disposed on the conveyor belt 131 at intervals in the conveying direction of the conveyor belt 131.
