Description

Technical Field

[0001] This invention relates to the field of cable production technology, and in particular to a spark testing device and method for cable production. Background Technology

[0002] The spark test device is an online testing equipment placed on the winding section of wire and cable products during production. Its main function is to use frequency voltage to detect whether the wire and cable products have copper leakage, broken insulation, surface impurities, insulation withstand voltage, etc. The spark test device applies a set voltage value to the insulated wire periodically according to a certain pattern, while the conductor part is grounded. This creates a voltage difference between the conductor and the insulation surface, thereby detecting whether there are defects in the insulation layer, so that the wire and cable products can pass the factory.

[0003] Existing spark testing equipment requires manual handling to gradually feed the cable into the test chamber during spark testing, which increases the workload of the staff. Therefore, by setting up a conveying structure to automatically feed the cable, manual handling of the cable is no longer required, thereby reducing the workload of the staff.

[0004] During long-term use, the metal bead chain may break at the point of contact with the cable due to wear and tear, resulting in missed cable inspections. Therefore, the worn metal bead chain needs to be replaced. However, the metal bead chain of existing spark testing devices is fixedly mounted on the conductive plate. When the metal bead chain is worn, it cannot be removed and replaced with a new one. This makes it easy for the worn metal bead chain to cause the cable to be missed, thereby reducing the test effect of the spark testing device for cable production. Summary of the Invention

[0005] The purpose of this invention is to provide a spark testing device and method for cable production, which solves the technical problem that in existing spark testing devices, the metal bead chain is fixedly mounted on a conductive plate. When the metal bead chain is worn, it cannot be removed and replaced with a new metal bead chain, which makes it easy for the worn metal bead chain to cause the cable to be missed in the test, thereby reducing the test effect of the spark testing device for cable production.

[0006] To achieve the above objectives, the present invention provides a spark testing device for cable production, comprising a test chamber and a protective cover, wherein the protective cover is movably connected to the test chamber and is located on the upper surface of the test chamber, and further comprising a fixing component and an installation component; the fixing component includes a rotating block and a limiting block, the rotating block being used to rotate the limiting block, the limiting block being movably connected to the test chamber and located on the side of the rotating block closer to the test chamber; the installation component includes a first conductive plate, a connecting block, a first conductive strip, a driving block, a second conductive plate, a supporting block, a second conductive strip, a metal bead chain, and a control block, wherein the first conductive plate is fixedly mounted on... Inside the protective cover, the connecting block is slidably connected to the first conductive plate and located on the lower surface of the first conductive plate. The first conductive strip is detachably connected to the connecting block and located on the lower surface of the connecting block. The driving block is used to drive the connecting block to move. The second conductive plate is fixed inside the protective cover. The support block is fixed on the lower surface of the second conductive plate. The second conductive strip is detachably connected to the support block and located on the lower surface of the support block. The metal bead chain is evenly distributed on the lower surfaces of the first conductive strip and the second conductive strip. The control block is used to control the cable to perform an electric spark test.

[0007] The rotating block includes a rotating rod and a handle. The rotating rod is fixed to the side of the limiting block near the protective cover and passes through the protective cover. The handle is fixed to the end of the rotating rod away from the limiting block.

[0008] The drive block includes a hydraulic cylinder and a telescopic rod. The hydraulic cylinder is fixed to the lower surface of the first conductive plate. The two ends of the telescopic rod are respectively connected to the output end of the hydraulic cylinder and the connecting block, and the telescopic rod is located between the hydraulic cylinder and the connecting block.

[0009] The spark testing device for cable production also includes a conveying component, which is used to convey the cable within the test chamber.

[0010] The conveying assembly includes a support plate, a control motor, a first transmission rod, a first conveying roller, and a first connecting rod. The support plate is fixed to the outside of the test chamber; the control motor is fixed to the upper surface of the support plate; the first transmission rod is connected to the output end of the control motor and passes through the test chamber; the first conveying roller is fixed to the end of the first transmission rod away from the control motor; and the first connecting rod is rotatably connected to the test chamber and fixed to the side of the first conveying roller away from the first transmission rod.

[0011] The conveying assembly further includes a connecting belt, a second transmission rod, a second conveying roller, a second connecting rod, and a limiting plate. The connecting belt is movably connected to the first transmission rod and is located outside the first transmission rod. The second transmission rod is movably connected to the connecting belt and is located inside the connecting belt, passing through the test chamber. The second conveying roller is fixed at the end of the second transmission rod near the test chamber. The second connecting rod is rotatably connected to the test chamber and is fixed at the side of the second conveying roller away from the second transmission rod. The limiting plate is fixed at the end of the second transmission rod away from the second conveying roller.

[0012] The present invention also provides a spark test method for cable production, comprising the following steps: The first conductive strip and the second conductive strip are fixedly installed on the lower surfaces of the first conductive plate and the second conductive plate, respectively. At this time, the metal bead chain is installed inside the protective cover. The protective cover is rotated outside the test chamber. When the protective cover is rotated to the top of the test chamber and completely covers the internal space of the test chamber, the protective cover is fixed above the test chamber. The cable is gradually conveyed from the slot into the test chamber, and at this time the cable will be gradually placed on the first conveyor roller and the second conveyor roller. Start the control motor, and the power output from the output end of the control motor drives the first transmission rod to rotate, thereby driving the first conveyor roller to rotate inside the test chamber; When the first transmission rod rotates, the first transmission rod drives the second transmission rod to rotate via the connecting belt, thereby driving the second transmission roller to rotate inside the test chamber; The rotation of the first and second conveying rollers inside the test chamber drives the cable to be conveyed from left to right within the test chamber. As the cable is conveyed from left to right within the test chamber, it gradually comes into contact with the metal bead chain, thus conducting an electrical spark test on the cable.

[0013] This invention discloses a spark testing device and method for cable production. By setting the fixing component, the fixing component can limit and fix the protective cover above the test chamber, thereby sealing the internal space of the test chamber. By setting the mounting component, the mounting component can remove the metal bead chain from under the conductive plate after the metal bead chain is worn, thereby avoiding the situation where the worn metal bead chain easily leads to the cable being missed in the test, thus improving the test effect of the spark testing device for cable production in spark testing of cables.

Detailed Implementation

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] First embodiment: Please see Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the overall structure of the spark testing device for cable production according to the first embodiment of the present invention. Figure 2 This is a cross-sectional view along the telescopic rod 118 according to the first embodiment of the present invention. Figure 3 This is a cross-sectional schematic diagram along the first bolt 111 according to the first embodiment of the present invention. Figure 4 This is a cross-sectional view along the second bolt 113 of the first embodiment of the present invention. The present invention provides a spark testing device for cable production, including a test chamber 101, a protective cover 102, a fixing component and an installation component. The fixing component includes a rotating block and a limiting block 103. The installation component includes a first conductive plate 104, a connecting block 105, a first conductive strip 106, a driving block, a second conductive plate 107, a support block 108, a second conductive strip 109, a metal bead chain 110, a control block, a first bolt 111, a first nut 112, a second bolt 113 and a second nut 114. The rotating block includes a rotating rod 115 and a handle 116. The driving block includes a hydraulic cylinder 117 and a telescopic rod 118. The control block includes a power module 119, a control module 120 and an operation panel 121.

[0025] In this embodiment, the fixing component is located on the side of the protective cover 102 near the test chamber 101, and is used to limit and fix the protective cover 102 above the test chamber 101, thereby sealing the internal space of the test chamber 101. The mounting component is located on the inner side of the protective cover 102, and is used to remove the metal bead chain 110 from under the conductive plate after the metal bead chain 110 is worn, thereby avoiding the situation that the worn metal bead chain 110 may cause the cable to be missed in the test, and thus improving the test effect of the spark test device for cable production on the spark test of the cable.

[0026] The protective cover 102 is movably connected to the test chamber 101 and is located on the upper surface of the test chamber 101. The rotating block is used to rotate the limiting block 103. The limiting block 103 is movably connected to the test chamber 101 and is located on the side of the rotating block closer to the test chamber 101. The first conductive plate 104 is fixedly disposed on the inner side of the protective cover 102. The connecting block 105 is slidably connected to the first conductive plate 104 and is located on the lower surface of the first conductive plate 104. The first conductive strip 106 is detachably connected to the connecting block 105 and is located on the lower surface of the connecting block 105. The driving block is used to drive the connecting block 105 to move. The second conductive plate 107 is fixedly disposed on the protective cover 102. Inside the cover 102, the support block 108 is fixed to the lower surface of the second conductive plate 107. The second conductive strip 109 is detachably connected to the support block 108 and located on the lower surface of the support block 108. The metal bead chain 110 is evenly distributed on the lower surfaces of the first conductive strip 106 and the second conductive strip 109. The control block is used to control the cable to perform an electric spark test. The protective cover 102 is connected to the test chamber 101 by a hinge. By fixing both sides of the hinge to the outside of the protective cover 102 and the test chamber 101 respectively, the protective cover 102 can rotate outside the test chamber 101, thereby allowing the protective cover 102 to rotate outside the test chamber 101. The internal space can be opened or closed. The test chamber 101 has a groove, and the limiting block 103 cooperates with the groove of the test chamber 101, so that the limiting block 103 can be embedded into the groove of the test chamber 101 or slide out of the groove of the test chamber 101. The first conductive plate 104 has a groove, and the connecting block 105 has a protrusion. The groove of the first conductive plate 104 and the protrusion of the connecting block 105 are both convex in shape, and the protrusion of the connecting block 105 cooperates with the groove of the first conductive plate 104, so that the protrusion of the connecting block 105 can slide laterally in the groove of the first conductive plate 104. The connecting block 105 also has a groove, and the first conductive strip The first conductive strip 106 has a protrusion, which engages with the groove of the connecting block 105, allowing the protrusion of the first conductive strip 106 to be embedded in the groove of the connecting block 105. The support block 108 has a groove, and the second conductive strip 109 has a protrusion, which engages with the groove of the support block 108, allowing the protrusion of the second conductive strip 109 to be embedded in the groove of the support block 108. The metal bead chain 110 is evenly arranged below the first conductive strip 106 and the second conductive strip 109. When the cable enters the test chamber 101, it will contact the metal bead chain 110, thereby enabling the cable to undergo an electric spark test.

[0027] Secondly, the rotating rod 115 is fixed to the side of the limiting block 103 near the protective cover 102 and passes through the protective cover 102; the handle 116 is fixed to the end of the rotating rod 115 away from the limiting block 103. The protective cover 102 has a through hole, and the rotating rod 115 passes through the through hole of the protective cover 102 and can rotate along the axis of the rotating rod 115 within the through hole of the protective cover 102. By holding the handle 116 and rotating the handle 116, one can... The rotating rod 115 can be driven to rotate along the axis of the rotating rod 115 within the through hole of the protective cover 102, which in turn can drive the limiting block 103 to rotate along the axis of the rotating rod 115 within the test chamber 101. Through the rotation of the limiting block 103 along the axis of the rotating rod 115 within the test chamber 101, the limiting block 103 can be embedded into the groove of the test chamber 101 or slide out of the groove of the test chamber 101.

[0028] Meanwhile, the hydraulic cylinder 117 is fixed to the lower surface of the first conductive plate 104; the two ends of the telescopic rod 118 are respectively connected to the output end of the hydraulic cylinder 117 and the connecting block 105. The telescopic rod 118 is located between the hydraulic cylinder 117 and the connecting block 105. The output end of the hydraulic cylinder 117 is connected to the telescopic rod 118 and drives the telescopic rod 118 to extend and retract, thereby driving the connecting block 105 to move laterally below the first conductive plate 104, and further driving the protrusion of the connecting block 105 to slide laterally in the groove of the first conductive plate 104.

[0029] Additionally, the power module 119 is located inside the test chamber 101; the control module 120 is electrically connected to both the power module 119 and the hydraulic cylinder 117, and is located inside the test chamber 101; the operation panel 121 is electrically connected to both the control module 120 and the power module 119, and is located outside the test chamber 101. The power module 119 provides power to both the control module 120 and the operation panel 121. The operation panel 121, the control module 120, and the hydraulic cylinder 117 are connected. The operation panel 121 is evenly distributed... The control panel 121 has operation buttons. By operating the corresponding operation buttons on the control panel 121, the control panel 121 will transmit corresponding operation commands to the control module 120. The control module 120 will then control the start and stop of the hydraulic cylinder 117 through the operation commands. The test chamber is equipped with sensors and alarms, both of which are electrically connected to the control module 120. This allows the sensors to detect electrical sparks. At the same time, when the alarm receives a non-compliance signal transmitted by the control module 120, the alarm will sound an alarm to remind the operator that the insulation layer of the cable is non-compliant.

[0030] Finally, the first bolt 111 is detached from the connecting block 105 and the first conductive strip 106, respectively, with the first bolt 111 passing through the connecting block 105 and the first conductive strip 106; the first nut 112 is detached from the first bolt 111 and sleeved on the outside of the first bolt 111; the second bolt 113 is detached from the support block 108 and the second conductive strip 109, respectively, with the second bolt 113 passing through the support block 108 and the second conductive strip 109; the second nut 114 is detached from the second bolt 113 and sleeved on the outside of the second bolt 113, with the connecting block 105 and the first conductive strip 106 being detached from the connecting block 105 and the first conductive strip 106. Each conductive strip 106 has a circular through hole. The first bolt 111 passes through the circular through holes of the connecting block 105 and the first conductive strip 106. The first nut 112 is threadedly connected to the first bolt 111, so that the first nut 112 can be tightened or loosened from the outside of the first bolt 111. Both the support block 108 and the second conductive strip 109 have circular through holes. The second bolt 113 passes through the circular through holes of the support block 108 and the second conductive strip 109. The second nut 114 is threadedly connected to the second bolt 113, so that the second nut 114 can be tightened or loosened from the outside of the second bolt 113.

[0031] When using the spark testing device for cable production according to this embodiment, the handle 116 is held and rotated, thereby causing the rotating rod 115 to rotate along the axis of the rotating rod 115 within the through hole of the protective cover 102. This, in turn, causes the limiting block 103 to rotate along the axis of the rotating rod 115 within the test chamber 101, allowing the limiting block 103 to slide out of the groove in the test chamber 101. This releases the fixed state of the protective cover 102 above the test chamber 101. The protective cover 102 is then rotated above the test chamber 101, opening the internal space of the protective cover 102. Then, the protrusion of the first conductive strip 106 is aligned with the... After aligning the groove of the connecting block 105, insert the protrusion of the first conductive strip 106 into the groove of the connecting block 105. When the circular through hole of the first conductive strip 106 is aligned with the circular through hole of the connecting block 105, insert the first bolt 111 into the circular through hole of the connecting block 105 and the first conductive strip 106, and tighten the first nut 112 on the outside of the first bolt 111, thereby fixing the first conductive strip 106 below the connecting block 105. This, in turn, fixes the metal bead chain 110 below the first conductive strip 106 below the first conductive plate 104. Align the protrusion of the second conductive strip 109 with the groove of the support block 108. After alignment, insert the protrusion of the second conductive strip 109 into the groove of the support block 108. When the circular through hole of the second conductive strip 109 is aligned with the circular through hole of the support block 108, insert the second bolt 113 into the circular through hole of the support block 108 and the second conductive strip 109, and tighten the second nut 114 on the outside of the second bolt 113, thereby fixing the second conductive strip 109 below the support block 108. This, in turn, fixes the metal bead chain 110 below the second conductive strip 109 below the second conductive plate 107, and combines this with the metal bead chain 110 below the first conductive strip 106 being fixedly installed on the first conductive plate 107. Below plate 104, the metal bead chain 110 is installed. Then, by operating the corresponding buttons on the operation panel 121, the operation panel 121 transmits corresponding operation commands to the control module 120. The control module 120 then controls the start and stop of the hydraulic cylinder 117 via these commands. The start of the hydraulic cylinder 117 causes the output power to drive the telescopic rod 118 to extend and retract, thereby causing the connecting block 105 to move laterally below the first conductive plate 104. This, in turn, causes the metal bead chain 110 below the first conductive strip 106 to move laterally within the protective cover 102.To allow for adjustment of the position of the metal bead chain 110 according to the condition of the cable to be tested, after installation, the protective cover 102 is rotated outside the test chamber 101. When the protective cover 102 is rotated above the test chamber 101 and completely covers the internal space of the test chamber 101, the limiting block 103 is rotated into the groove of the test chamber 101, thereby limiting and fixing the protective cover 102 above the test chamber 101, thus sealing the internal space of the test chamber 101. At this time, the cable is inserted into the slot of the test chamber 101. The cable is automatically conveyed from left to right within the test chamber 101, causing it to come into contact with the metal bead chain 110 during this process. This allows for an electric spark test on the cable. When the cable's insulation is non-conductive or has insufficient insulation performance, an electric spark will be generated between the electrode and the cable. Upon detecting this spark, the sensor transmits a signal to the control module 120. The control module 120 then determines whether the cable's insulation is qualified based on the signal. If the cable's insulation is unqualified, an alarm will sound, alerting the operator that the cable's insulation is substandard.

[0032] In summary, by setting the fixing component, the protective cover 102 can be limited and fixed above the test chamber 101, thereby sealing the internal space of the test chamber 101. By setting the mounting component, the mounting component can remove the metal bead chain 110 from under the conductive plate after the metal bead chain 110 is worn, thereby avoiding the situation where the worn metal bead chain 110 easily leads to the cable being missed in the test, and thus improving the test effect of the spark test device for cable production on the spark test of the cable.

[0033] Second embodiment: Based on the first embodiment, please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the conveying assembly of the spark testing device for cable production according to the second embodiment of the present invention. Figure 6 This is a cross-sectional schematic diagram along the second transmission rod 207 of the second embodiment of the present invention. The present invention provides a spark testing device for cable production, which further includes a transmission assembly. The transmission assembly includes a support plate 201, a control motor 202, a first transmission rod 203, a first transmission roller 204, a first connecting rod 205, a connecting belt 206, a second transmission rod 207, a second transmission roller 208, a second connecting rod 209, and a limiting plate 210.

[0034] In this embodiment, the conveying component is located on the side of the test chamber 101 away from the protective cover 102, and is used to automatically convey the cable, thereby eliminating the need for manual conveying and reducing the labor intensity of the staff.

[0035] The support plate 201 is fixed to the outside of the test chamber 101; the control motor 202 is fixed to the upper surface of the support plate 201; the first transmission rod 203 is connected to the output end of the control motor 202 and passes through the test chamber 101; the first conveying roller 204 is fixed to the end of the first transmission rod 203 away from the control motor 202; the first connecting rod 205 is rotatably connected to the test chamber 101 and fixed to the side of the first conveying roller 204 away from the first transmission rod 203; the test chamber 101 has a circular shape. The first transmission rod 203 passes through the circular through hole of the test chamber 101. The first transmission rod 203, the first conveying roller 204, and the first connecting rod 205 are coaxially arranged. The output end of the control motor 202 is connected to the first transmission rod 203 and drives the first transmission rod 203 to rotate along its own axis, thereby driving the first conveying roller 204 to rotate along its own axis inside the test chamber 101, and further driving the first connecting rod 205 to rotate along its own axis inside the test chamber 101.

[0036] Secondly, the connecting belt 206 is movably connected to the first transmission rod 203 and is located outside the first transmission rod 203; the second transmission rod 207 is movably connected to the connecting belt 206 and is located inside the connecting belt 206, and passes through the test chamber 101; the second conveying roller 208 is fixedly mounted on the end of the second transmission rod 207 near the test chamber 101; the second connecting rod 209 is rotatably connected to the test chamber 101 and is fixedly mounted on the side of the second conveying roller 208 away from the second transmission rod 207; the limiting plate 210 is fixedly mounted on the end of the second transmission rod 207 away from the second conveying roller 208, and the first conveying roller 204 and The second conveyor rollers 208 are at the same height. The first transmission rod 203 and the second transmission rod 207 are connected by the connecting belt 206, so that the rotation of the first transmission rod 203 along its own axis can drive the second transmission rod 207 to rotate along its own axis, thereby driving the second conveyor roller 208 to rotate along its own axis in the test chamber 101, and further driving the second connecting rod 209 to rotate along its own axis in the test chamber 101. The limiting plate 210 can limit the extreme position of the second transmission rod 207, thereby preventing the connecting belt 206 from slipping off the outside of the second transmission rod 207.

[0037] When using the spark testing device for cable production according to this embodiment, during the electric spark test of the cable, the cable is inserted into the slot of the test chamber 101, so that the cable is gradually placed on the first conveyor roller 204 and the second conveyor roller 208. Then, the control motor 202 is started, so that the power output from the output end of the control motor 202 drives the first transmission rod 203 to rotate along its own axis, thereby driving the first conveyor roller 204 to rotate along its own axis within the test chamber 101. Through the rotation of the first transmission rod 203 along its own axis, the cable can be subjected to the electric spark test. The connecting belt 206 drives the second transmission rod 207 to rotate along its own axis, which in turn drives the second transmission roller 208 to rotate along its own axis inside the test chamber 101. Through the rotation of the first transmission roller 204 and the second transmission roller 208 along their own axes inside the test chamber 101, the cables on the first transmission roller 204 and the second transmission roller 208 can be driven to be conveyed from left to right inside the test chamber 101. When the cables are conveyed from left to right inside the test chamber 101, the cables will gradually come into contact with the metal bead chain 110 to conduct an electric spark test on the cables.

[0038] Third embodiment: Based on the second embodiment, please refer to Figure 7 , Figure 7 This is a flowchart illustrating the spark testing method for cable production according to the third embodiment of the present invention. The present invention also provides a spark testing method for cable production, comprising the following steps: S101. The first conductive strip 106 and the second conductive strip 109 are respectively fixedly installed on the lower surfaces of the first conductive plate 104 and the second conductive plate 107. At this time, the metal bead chain 110 is installed inside the protective cover 102. S102, allow the protective cover 102 to rotate outside the test chamber 101. When the protective cover 102 is rotated to the top of the test chamber 101 and completely covers the internal space of the test chamber 101, allow the protective cover 102 to be limited and fixed above the test chamber 101.

The power output from the output end of the control motor 202 drives the first transmission rod 203 to rotate, thereby driving the first conveying roller 204 to rotate inside the test chamber 101. S105. When the first transmission rod 203 rotates, the first transmission rod 203 drives the second transmission rod 207 to rotate through the connecting belt 206, thereby driving the second transmission roller 208 to rotate inside the test chamber 101. S106. The rotation of the first conveying roller 204 and the second conveying roller 208 within the test chamber 101 drives the cable to be conveyed from left to right within the test chamber 101. S107. When the cable is conveyed from left to right in the test chamber 101, the cable will gradually come into contact with the metal bead chain 110 to conduct an electric spark test on the cable.

[0039] When using the spark test method for cable production according to this embodiment, the handle 116 is held and rotated, thereby causing the rotating rod 115 to rotate along the axis of the rotating rod 115 within the through hole of the protective cover 102. This, in turn, causes the limiting block 103 to rotate along the axis of the rotating rod 115 within the test chamber 101, allowing the limiting block 103 to slide out of the groove in the test chamber 101. This releases the fixed state of the protective cover 102 above the test chamber 101. The protective cover 102 is then rotated above the test chamber 101, opening the internal space of the protective cover 102. Then, the protrusion of the first conductive strip 106 is aligned with the... After aligning the groove of the connecting block 105, insert the protrusion of the first conductive strip 106 into the groove of the connecting block 105. When the circular through hole of the first conductive strip 106 is aligned with the circular through hole of the connecting block 105, insert the first bolt 111 into the circular through hole of the connecting block 105 and the first conductive strip 106, and tighten the first nut 112 on the outside of the first bolt 111, thereby fixing the first conductive strip 106 below the connecting block 105. This, in turn, fixes the metal bead chain 110 below the first conductive strip 106 below the first conductive plate 104. Align the protrusion of the second conductive strip 109 with the groove of the support block 108. After alignment, insert the protrusion of the second conductive strip 109 into the groove of the support block 108. When the circular through hole of the second conductive strip 109 is aligned with the circular through hole of the support block 108, insert the second bolt 113 into the circular through hole of the support block 108 and the second conductive strip 109, and tighten the second nut 114 on the outside of the second bolt 113, thereby fixing the second conductive strip 109 below the support block 108. This, in turn, fixes the metal bead chain 110 below the second conductive strip 109 below the second conductive plate 107, and combines this with the metal bead chain 110 below the first conductive strip 106 being fixedly installed on the first conductive plate 107. Below plate 104, the metal bead chain 110 is installed. Then, by operating the corresponding buttons on the operation panel 121, the operation panel 121 transmits corresponding operation commands to the control module 120. The control module 120 then controls the start and stop of the hydraulic cylinder 117 via these commands. The start of the hydraulic cylinder 117 causes the output power to drive the telescopic rod 118 to extend and retract, thereby causing the connecting block 105 to move laterally below the first conductive plate 104. This, in turn, causes the metal bead chain 110 below the first conductive strip 106 to move laterally within the protective cover 102.To allow for adjustment of the position of the metal bead chain 110 according to the condition of the cable to be tested, after installation, the protective cover 102 is rotated outside the test chamber 101. When the protective cover 102 is rotated above the test chamber 101 and completely covers the internal space of the test chamber 101, the limiting block 103 is rotated into the groove of the test chamber 101, thereby limiting and fixing the protective cover 102 above the test chamber 101, thus sealing the internal space of the test chamber 101 to facilitate the electric spark test of the cable. During the electric spark test, the cable is inserted into the slot of the test chamber 101, so that the cable will be gradually placed on the first conveyor roller 204 and the second conveyor roller 208. Then, the control motor 202 is started, so that the power output from the output end of the control motor 202 drives the first transmission rod 203 to rotate along its own axis, thereby driving the first conveyor roller 204 to rotate along its own axis inside the test chamber 101. The rotation of the moving rod 203 along its own axis drives the second transmission rod 207 to rotate along its own axis via the connecting belt 206, which in turn drives the second conveyor roller 208 to rotate along its own axis within the test chamber 101. The rotation of the first conveyor roller 204 and the second conveyor roller 208 along their own axes within the test chamber 101 causes the cable on each roller to be conveyed from left to right within the test chamber 101. As the cable is conveyed from left to right within the test chamber 101, it gradually comes into contact with the metal bead chain 110, performing an electric spark test. When the cable insulation layer is non-conductive or has insufficient insulation performance, an electric spark will be generated between the electrode and the cable. Upon detecting the electric spark, the sensor transmits a signal to the control module 120. The control module 120 determines whether the cable insulation layer is qualified based on the signal. If the cable insulation layer is unqualified, an alarm will sound, alerting the operator that the cable insulation layer is unqualified.
