Description

Technical Field

[0001] This invention relates to the field of ceramic sheet pressure resistance testing technology, specifically a ceramic sheet pressure resistance testing device with automatic loading and unloading function. Background Technology

[0002] Ceramic plates are core components commonly used in high-voltage equipment, such as capacitors and varistors. Their function is to isolate high-voltage current and prevent high-voltage current from breaking down the equipment.

[0003] During the manufacturing process, ceramic sheets may develop tiny pores, cracks, or impurities during sintering, resulting in insufficient insulation performance. Insufficient insulation performance can lead to short circuits, arc discharges, or even fires in equipment. Therefore, it is necessary to conduct withstand voltage tests on ceramic sheets to ensure their safety and stability in high-voltage environments.

[0004] Traditional ceramic sheet withstand voltage testing equipment often requires manual loading and unloading of ceramic sheets, which is not only inefficient and prone to errors, but also requires the addition of insulating oil to perform withstand voltage tests, which can lead to product scrap. Furthermore, when a breakdown occurs due to insulation problems in the test sample, traditional testing equipment cannot cut off the high-voltage current in time, which can lead to a large short-circuit current that burns the fault point. Summary of the Invention

[0005] The purpose of this invention is to provide a ceramic sheet pressure resistance testing device with automatic loading and unloading function to solve the problems raised in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A ceramic sheet pressure resistance testing device with automatic loading and unloading function. The testing device includes a frame, a conveying mechanism, material boxes, a robotic arm, a loading and handling mechanism, a testing mechanism, an inspection mechanism, a laser marking machine, and an unloading mechanism. The frame and the conveying mechanism are fixedly connected. Several material boxes are provided, and several material boxes abut against the conveying mechanism. One material box is fixedly connected to the frame. The robotic arm is fixedly connected to the frame. The loading and handling mechanism is fixedly connected to the frame. There are six testing mechanisms, and the six testing mechanisms are fixedly connected to the frame. The six testing mechanisms are staggered vertically. The laser marking machine is fixedly connected to the frame. The unloading mechanism is fixedly connected to the frame. A buffer platform is provided on the frame.

[0008] The system comprises a frame-mounted conveyor mechanism, material bins, a robotic arm, a loading and handling mechanism, a testing mechanism, an inspection mechanism, a laser marking machine, and a unloading mechanism, providing a stable working environment for the testing equipment. The conveyor belt of the conveyor mechanism serves as the feed line, transporting the material bins containing ceramic sheets towards the robotic arm. The robotic arm, driven by grippers, transfers the ceramic sheets from the material bins to the loading and handling mechanism. This mechanism separates stacked ceramic sheets and transports them to the testing mechanism. The robotic arm then picks up the separated ceramic sheets and places them into the testing mechanism for pressure resistance testing. Six testing mechanisms provide six independent testing channels, allowing the robotic arm to perform multiple tests simultaneously. By placing six ceramic tiles into the testing mechanism, the testing efficiency is improved. By setting up six testing mechanisms, the multi-station optical inspection system reduces the equipment's missed detection rate. The six testing mechanisms are staggered vertically to prevent mutual interference. A laser marking machine marks qualified ceramic tiles. Through the unloading mechanism, qualified products are placed in the material box on the conveyor mechanism and conveyed away from the opposite direction of feeding. Defective products are placed in the material box on the frame to separate qualified and defective products. A buffer platform is provided on the frame so that after the loading and handling mechanism is full of ceramic tiles, the robotic arm can place the ceramic tiles on the buffer platform to avoid the conveyor belt of the conveyor mechanism stopping and affecting the operation of the unloading mechanism.

[0009] Furthermore, the material handling mechanism includes a transverse linear module, a sliding plate, a cylinder, a first fixed plate, a linear guide rail, a connecting plate, grippers, and a stopper. The transverse linear module is fixedly connected to the frame, the sliding end of the transverse linear module is fixedly connected to the sliding plate, the cylinder is fixedly connected to the first fixed plate, the cylinder output end is fixedly connected to the connecting plate, the first fixed plate is fixedly connected to the linear guide rail, the connecting plate is fixedly connected to the linear guide rail, the sliding end of the linear guide rail is fixedly connected to the sliding plate, the connecting plate is fixedly connected to the grippers, and the stopper abuts against the grippers.

[0010] The cylinder and the first fixing plate are fixed together. The first fixing plate is fixed together with the linear guide rail. The cylinder output end is fixed together with the connecting plate, so that the cylinder can drive the connecting plate to move up and down. The clamp and the plug abut together, so that the plug is clamped by the clamp. The plug can move laterally by being fixedly connected to the sliding plate of the transverse linear module, so that it can move towards the testing mechanism.

[0011] Furthermore, the stopper includes a first box, a stop block, and dividing teeth. The first box and the stop block are fixedly connected. The first box is provided with a placement groove, and there are several dividing teeth, which are placed at both ends of the placement groove.

[0012] The first housing has a placement slot, which allows the robotic arm to place ceramic pieces into the slot. Several separating teeth are provided at both ends of the placement slot, which enables the ceramic pieces to be automatically separated, making it easier for the robotic arm to place individual ceramic pieces into the testing mechanism.

[0013] Furthermore, the testing mechanism includes an AC / DC voltage divider, an AC / DC pneumatic converter, an AC / DC capacitive voltage divider, a metal-cased test transformer, a protection unit, a tooling box, and a microamplitude current sampling box. The AC / DC voltage divider and the AC / DC pneumatic converter are fixedly connected, the AC / DC pneumatic converter and the AC / DC capacitive voltage divider are fixedly connected, the metal-cased test transformer and the AC / DC capacitive voltage divider are fixedly connected, the AC / DC pneumatic converter and the tooling box are connected by wires, the tooling box and the microamplitude current sampling box are fixedly connected, and the protection unit and the tooling box are fixedly connected.

[0014] A metal-cased test transformer serves as the power source, delivering electrical energy to an AC / DC capacitive voltage divider. This divider, along with the AC / DC capacitor divider, reduces the output voltage of the metal-cased test transformer to a suitable measurement voltage. Through an AC / DC pneumatic converter and wiring connections to the tooling box, the electrical energy is delivered to the tooling box for testing the ceramic plate. The tooling box and microamplitude current sampling box are fixedly connected, allowing for the measurement of the current in capacitive devices within the circuit or system. A protection unit, fixedly connected to the tooling box, enables the protection unit to instantly and rapidly cut off the high-voltage current in the event of insulation failure in the ceramic plate, preventing large short-circuit currents from burning out the fault point.

[0015] Furthermore, the protection unit includes a circuit board, a potentiometer, a vacuum tube, and a relay. The circuit board and the potentiometer are fixedly connected, the circuit board and the vacuum tube are fixedly connected, and the relay and the circuit board are fixedly connected.

[0016] The current in the current-sensitive fixture box is detected by a relay on the circuit board. When the current is too high, the relay control circuit closes, and the electron tube discharges. The current is adjusted by controlling the resistance value through a potentiometer, thereby controlling the discharge magnitude of the electron tube and thus providing overvoltage protection. This releases excess voltage in the fixture box and prevents large short-circuit currents from burning the ceramic chip's fault point.

[0017] Furthermore, the tooling box includes a second box body, a cover plate, an electrode plate, a high-voltage inlet port, and a grounding port. The second box body and the cover plate are hinged together. There are two electrode plates, one of which is fixedly connected to the cover plate and the other is fixedly connected to the second box body. The high-voltage inlet port is fixedly connected to the cover plate, the grounding port is fixedly connected to the second box body, and the grounding port is fixedly connected to the microamplitude current sampling box. The material of the second box body is plexiglass.

[0018] By using plexiglass as the material for the No. 2 enclosure, which has excellent electrical insulation properties, the No. 2 enclosure can maintain stable electrical performance in high-voltage testing environments, thus ensuring testing accuracy. The No. 2 enclosure and the cover plate are connected by a hinge, allowing the tooling box to open with a flip-top for easy access to test samples. Electrode plates are installed inside the No. 2 enclosure and on the cover plate, with soft conductive material on their surfaces, enabling the ceramic sheet to be tested in air. A high-voltage inlet port is provided on the cover plate, which is connected to an AC / DC pneumatic converter wire to deliver current to the tooling box for testing the ceramic sheet. A grounding port is provided at the bottom of the No. 2 enclosure, which is connected to a microamplitude current sampling box, enabling the measurement of the current of capacitive devices in circuits or systems.

[0019] Furthermore, the material box includes a placement plate, a limiting rod, and a handle. The placement plate and the limiting rod are fixedly connected, and the handle and the placement plate are fixedly connected.

[0020] The ceramic sheet is placed on the placement plate, and several limiting rods are set to limit the ceramic sheet on the placement plate, so that the ceramic sheet is accurately placed in the material box.

[0021] Furthermore, the testing mechanism includes a first camera, a light source, and a second fixing plate. The second fixing plate is fixedly connected to the first camera, and the light source is fixedly connected to the second fixing plate.

[0022] A camera is set up on the conveyor belt for material feeding. The ceramic pieces are visually inspected to distinguish between qualified and defective products, which facilitates classification by the feeding mechanism. Light is emitted from a light source to illuminate the ceramic pieces, preventing ambient light from affecting the inspection results.

[0023] Furthermore, the feeding mechanism includes a Z-axis linear module, an X-axis linear module, an angle adjustment mechanism, a Y-axis linear module for inserting parts, a third fixing plate, and a second camera. The Z-axis linear module is fixedly connected to the frame, the sliding end of the Z-axis linear module is fixedly connected to the X-axis linear module, the sliding end of the X-axis linear module is fixedly connected to the angle adjustment mechanism, the rotating end of the angle adjustment mechanism is fixedly connected to the Y-axis linear module for inserting parts, the third fixing plate is fixedly connected to the frame, and the second camera is fixedly connected to the third fixing plate.

[0024] The Z-axis linear module, X-axis linear module, and Y-axis linear module for inserting ceramic pieces are used to move the inserts on the Y-axis linear module. The Y-axis linear module for inserting ceramic pieces is used to grasp the ceramic pieces. The second camera on the third fixed plate performs visual positioning of the Y-axis linear module for inserting ceramic pieces. The angle adjustment mechanism adjusts the angle of the Y-axis linear module for inserting ceramic pieces so that the ceramic pieces can be accurately placed into the material box.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. By using a robotic arm in conjunction with a conveying mechanism, a loading and unloading mechanism, and an unloading mechanism to replace manual loading and unloading operations, errors can be effectively prevented and testing efficiency can be significantly improved. By setting up six testing mechanisms and providing six independent testing channels, the robotic arm can place six ceramic pieces into the testing mechanism at a time, thereby improving testing efficiency.

[0027] 2. The current in the current-carrying box is detected by the relay on the circuit board. When the current is too high, the relay control circuit closes, and the electron tube discharges. The current is adjusted by controlling the resistance value through the potentiometer, thereby controlling the discharge size of the electron tube and releasing the excess voltage in the tooling box. This provides overvoltage protection and prevents the large short-circuit current from burning the fault point of the ceramic sheet.

[0028] 3. By using plexiglass as the material for the No. 2 enclosure, the No. 2 enclosure can maintain stable electrical performance in a high-voltage testing environment, thereby ensuring the accuracy of the test. The No. 2 enclosure and the cover plate are connected by a hinge, making the tooling box openable by flip-top, which facilitates the loading and unloading of test samples. By setting electrode plates inside the No. 2 enclosure and on the cover plate, and applying a soft conductive material to the surface of the electrode plates, the ceramic plates can be tested in the air, thus eliminating the need for insulating oil and avoiding product scrap.

[0041] 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.

[0042] Example: Figure 1As shown, the present invention provides a technical solution for a ceramic sheet pressure resistance testing device with automatic loading and unloading function. The testing device includes a frame 1, a conveying mechanism 2, a material box 3, a robotic arm 4, a loading and handling mechanism 5, a testing mechanism 6, a detection mechanism 7, a laser marking machine 8, and a unloading mechanism 9. The frame 1 and the conveying mechanism 2 are fixedly connected. Several material boxes 3 are provided, and several material boxes 3 abut against the conveying mechanism 2. One material box 3 is fixedly connected to the frame 1. The robotic arm 4 is fixedly connected to the frame 1. The loading and handling mechanism 5 is fixedly connected to the frame 1. There are six testing mechanisms 6, and the six testing mechanisms 6 are fixedly connected to the frame 1. The six testing mechanisms 7 are provided, and the six testing mechanisms 7 are fixedly connected to the frame 1. The six testing mechanisms 7 are staggered vertically. The laser marking machine 8 is fixedly connected to the frame 1. The unloading mechanism 9 is fixedly connected to the frame 1. A buffer platform 12 is provided on the frame 1.

[0043] The frame 1 secures the conveyor mechanism 2, material box 3, robotic arm 4, loading and handling mechanism 5, testing mechanism 6, inspection mechanism 7, laser marking machine 8, and unloading mechanism 9, providing a stable working environment for the testing equipment. The conveyor belt of the conveyor mechanism 2 serves as the feed line, transporting the material box 3 containing ceramic sheets towards the robotic arm 4. The grippers on the robotic arm 4 drive the transfer of the ceramic sheets from the material box 3 to the loading and handling mechanism 5. The loading and handling mechanism 5 separates stacked ceramic sheets and transports them to the testing mechanism 6. The robotic arm 4 picks up the separated ceramic sheets and places them in the testing mechanism 6 for pressure resistance testing. By setting up six testing mechanisms 6, six independent testing channels are provided, allowing the robotic arm 4 to perform tests simultaneously. Six ceramic tiles can be placed in the testing mechanism 6 to improve testing efficiency. By setting up six testing mechanisms 7, the multi-station optical inspection system reduces the equipment's missed detection rate. The six testing mechanisms 7 are staggered vertically to prevent mutual interference. The laser marking machine 8 marks qualified ceramic tiles. The unloading mechanism 9 places qualified products into the material box 3 on the conveying mechanism 2 and conveys them out from the opposite direction of feeding. Defective products are placed into the material box 3 on the frame 1 to separate qualified and defective products. The frame 1 is equipped with a buffer platform 12, so that after the loading and handling mechanism 5 is full of ceramic tiles, the robotic arm 4 can place the ceramic tiles into the buffer platform 12 to prevent the conveyor belt of the conveying mechanism 2 from stopping and affecting the operation of the unloading mechanism 9.

[0044] like Figures 2-4As shown, the material handling mechanism 5 includes a horizontal linear module 51, a sliding plate 52, a cylinder 53, a first fixed plate 54, a linear guide rail 55, a connecting plate 56, a gripper 57, and a stopper 58. The horizontal linear module 51 is fixedly connected to the frame 1. The sliding end of the horizontal linear module 51 is fixedly connected to the sliding plate 52. The cylinder 53 is fixedly connected to the first fixed plate 54. The output end of the cylinder 53 is fixedly connected to the connecting plate 56. The first fixed plate 54 is fixedly connected to the linear guide rail 55. The connecting plate 56 is fixedly connected to the linear guide rail 55. The sliding end of the linear guide rail 55 is fixedly connected to the sliding plate 52. The connecting plate 56 is fixedly connected to the gripper 57. The stopper 58 abuts against the gripper 57.

[0045] The cylinder 53 is fixed to the first fixing plate 54, which is fixed to the linear guide rail 55. The output end of the cylinder 53 is fixed to the connecting plate 56, so that the cylinder 53 can drive the connecting plate 56 to move up and down. The clamp 57 and the plug 58 abut against each other, so that the plug 58 is clamped by the clamp 57. The sliding end of the transverse linear module 51 is fixedly connected to the sliding plate 52, so that the plug 58 can move laterally, thereby moving towards the testing mechanism 6.

[0046] like Figure 3 and Figure 4 As shown, the stopper 58 includes a first box 581, a stopper block 582 and a separator tooth 583. The first box 581 and the stopper block 582 are fixedly connected. The first box 581 is provided with a placement groove 5811. Several separator teeth 583 are provided, and several separator teeth 583 are placed at both ends of the placement groove 5811.

[0047] The first housing 581 is provided with a placement slot 5811, which allows the robotic arm 4 to place ceramic pieces into the placement slot 5811. Several separating teeth 583 are provided and are located at both ends of the placement slot 5811, which allows the ceramic pieces to be automatically separated, thus making it easier for the robotic arm 4 to place individual ceramic pieces into the testing mechanism 6.

[0048] like Figure 5 , Figure 6 and Figure 7 As shown, the test mechanism 6 includes an AC / DC voltage divider 61, an AC / DC pneumatic converter 62, an AC / DC capacitor voltage divider 63, a metal-cased test transformer 64, a protection unit 65, a tooling box 66, and a microamplitude current sampling box 67. The AC / DC voltage divider 61 and the AC / DC pneumatic converter 62 are fixedly connected, the AC / DC pneumatic converter 62 and the AC / DC capacitor voltage divider 63 are fixedly connected, the metal-cased test transformer 64 and the AC / DC capacitor voltage divider 63 are fixedly connected, the AC / DC pneumatic converter 62 and the tooling box 66 are connected by wires, the tooling box 66 and the microamplitude current sampling box 67 are fixedly connected, and the protection unit 65 and the tooling box 66 are fixedly connected.

[0049] The iron-shell test transformer 64 serves as the power source, delivering electrical energy to the AC / DC capacitive voltage divider 63. Through the AC / DC capacitive voltage divider 63 and the AC / DC voltage divider 61, the voltage output from the iron-shell test transformer 64 is reduced to a suitable measurement voltage. The test electrical energy is then delivered to the tooling box 66 via a wire connection between the AC / DC pneumatic converter 62 and the tooling box 66, allowing for the testing of the ceramic plate. The tooling box 66 is fixedly connected to the microamplitude current sampling box 67, thereby measuring the current of capacitive devices in the circuit or system. The protection unit 65 is fixedly connected to the tooling box 66, enabling the protection unit 65 to instantly and rapidly cut off the high-voltage current in the event of insulation failure in the ceramic plate, thus preventing large short-circuit currents from burning the fault point.

[0050] like Figure 7 As shown, the protection unit 65 includes a circuit board 651, a potentiometer 652, an electron tube 653, and a relay 654. The circuit board 651 and the potentiometer 652 are fixedly connected, the circuit board 651 and the electron tube 653 are fixedly connected, and the relay 654 and the circuit board 651 are fixedly connected.

[0051] The current in the current-feeding box 66 is detected by the relay 654 on the circuit board 651. When the current is too large, the relay 654 controls the circuit to close, and discharges through the electron tube 653. The current is adjusted by controlling the resistance value through the potentiometer 652, thereby controlling the discharge magnitude of the electron tube 653, thus performing overvoltage protection, releasing the excess voltage in the tooling box 66, and preventing the fault point of the ceramic sheet from being burned by a large short circuit current.

[0052] like Figure 5 and Figure 7 As shown, the tooling box 66 includes a second box 661, a cover plate 662, an electrode plate 663, a high-voltage inlet port 664, and a grounding port 665. The second box 661 and the cover plate 662 are hinged together. There are two electrode plates 663. One electrode plate 663 is fixedly connected to the cover plate 662, and the other electrode plate 663 is fixedly connected to the second box 661. The high-voltage inlet port 664 is fixedly connected to the cover plate 662. The grounding port 665 is fixedly connected to the second box 661 and to the microamplitude current sampling box 67. The material of the second box 661 is plexiglass.

[0053] By using plexiglass as the material for the second enclosure 661, which has excellent electrical insulation properties, the second enclosure 661 can maintain stable electrical performance in a high-voltage testing environment, thereby ensuring the accuracy of the test. The second enclosure 661 and the cover plate 662 are hinged together, making the tooling box 66 a flip-top that facilitates the loading and unloading of test samples. Electrode plates 663 are set inside the second enclosure 661 and on the cover plate 662. The surface of the electrode plates 663 is covered with a soft conductive material, allowing the ceramic sheet to be tested in air. A high-voltage inlet port 664 is set on the cover plate 662, which is connected to the AC / DC pneumatic converter 62 wire, thereby transmitting current to the tooling box 66 to test the ceramic sheet. A grounding port 665 is set at the bottom of the second enclosure 661, which is connected to the microamplitude current sampling box 67, enabling the measurement of the current of capacitive devices in the circuit or system.

[0054] like Figure 8 As shown, the material box 3 includes a placement plate 31, a limiting rod 32, and a handle 33. The placement plate 31 and the limiting rod 32 are fixedly connected, and the handle 33 is fixedly connected to the placement plate 31.

[0055] The ceramic sheet is placed on the placement plate 31. Several limiting rods 32 are set to limit the ceramic sheet on the placement plate 31, so that the ceramic sheet is accurately placed in the material box 3.

[0056] like Figure 9 As shown, the detection mechanism 7 includes a first camera 71, a light source 72, and a second fixing plate 73. The second fixing plate 73 is fixedly connected to the first camera 71, and the light source 72 is fixedly connected to the second fixing plate 73.

[0057] A camera 71 is set on the conveyor belt for material feeding. The ceramic pieces are visually inspected to distinguish between qualified and defective products, which facilitates classification by the feeding mechanism 9. Light is emitted by a light source 72 to illuminate the ceramic pieces, preventing ambient light from affecting the inspection results.

[0058] like Figure 10 and Figure 11 As shown, the unloading mechanism 9 includes a Z-axis linear module 91, an X-axis linear module 92, an angle adjustment mechanism 93, a Y-axis linear module 94 for inserting parts, a third fixing plate 95, and a second camera 96. The Z-axis linear module 91 is fixedly connected to the frame 1. The sliding end of the Z-axis linear module 91 is fixedly connected to the X-axis linear module 92. The sliding end of the X-axis linear module 92 is fixedly connected to the angle adjustment mechanism 93. The rotating end of the angle adjustment mechanism 93 is fixedly connected to the Y-axis linear module 94 for inserting parts. The third fixing plate 95 is fixedly connected to the frame 1. The second camera 96 ​​is fixedly connected to the third fixing plate 95.

[0059] The inserts on the Y-axis linear module 94 are moved by the Z-axis linear module 91, the X-axis linear module 92 and the insert Y-axis linear module 94. The insert Y-axis linear module 94 is used to grasp the ceramic sheet. The second camera 96 ​​on the third fixing plate 95 is used to visually position the insert Y-axis linear module 94. The angle of the insert Y-axis linear module 94 is adjusted by the angle adjustment mechanism 93 so that the ceramic sheet can be accurately placed into the material box 3.

[0060] Working principle: The conveyor belt of the conveyor mechanism 2 transports the ceramic sheet-containing box 3. The driven robotic arm 4 transfers the ceramic sheet from the box 3 to the cassette 58. Several separating teeth 583 are provided to automatically separate the ceramic sheet. The transverse linear module 51 transfers the cassette 58 to the side of the testing mechanism 6. The robotic arm 4 picks up the separated ceramic sheet and places it into the tooling box 66. Through the iron-shell test transformer 64, electrical energy is transmitted to the AC / DC pneumatic converter 62. The AC / DC pneumatic converter 62 and the tooling box 66 are connected by wires, so that the electrical energy for testing is transmitted to the tooling box 66, thereby testing the ceramic sheet. The protection unit 65 detects insulation problems in the ceramic sheet. When a breakdown occurs, the protection unit 65 can instantly and quickly cut off the high-voltage current, thereby preventing the large short-circuit current from burning the fault point. By setting up six detection mechanisms 7, multi-station optical detection is carried out. The laser marking machine 8 marks the qualified ceramic pieces. The unloading mechanism 9 places the qualified products into the material box 3 on the conveying mechanism 2 and conveys them away from the opposite direction of feeding. The defective products are placed into the material box 3 on the frame 1, so that qualified products and defective products are separated. The frame 1 is equipped with a buffer platform 12, so that after the loading and handling mechanism 5 is full of ceramic pieces, the robotic arm 4 can place the ceramic pieces into the buffer platform 12, so as to avoid the conveyor belt of the conveying mechanism 2 stopping and affecting the operation of the unloading mechanism 9.
