Description

Technical Field

[0001] This invention relates to the technical field of electronic component testing, specifically to an insulating base withstand voltage breakdown testing device. Background Technology

[0002] Insulating bases are commonly used wiring structures in circuit systems. They wrap the phase electrodes with insulating material to achieve insulation between adjacent phase electrodes and between the phase electrodes and ground. Once arcing or electrical breakdown occurs between adjacent phase electrodes or between the phase electrodes and ground, short circuits and other problems can easily occur, affecting safety. Therefore, it is necessary to perform withstand voltage breakdown testing on the insulating bases.

[0003] Currently, existing devices for withstand voltage breakdown of insulating bases include a placement base with detection electrodes connected to a leakage current detection circuit. During testing, the detection electrodes are inserted into the phase electrodes on the insulating base. If the current in the leakage current detection circuit does not change, the phase electrodes of the insulating base are not broken down by voltage, indicating excellent insulation performance and making it a semi-qualified product. If the current in the leakage current detection circuit changes, the phase electrodes of the insulating base are broken down by voltage, indicating poor insulation performance and making it a questionable product. For example, patent CN206594258U discloses an insulating boot breakdown judgment device, in which the housing is divided into several storage chambers. The power supply is connected to a voltage regulator through wires. Several wires from the voltage regulator are connected to a switching device and then enter several storage chambers of the housing. Each storage chamber is equipped with a leakage current detection wire, which is connected to an ammeter and then connected to the power supply. The housing is equivalent to the aforementioned placement base, the detection electrodes are equivalent to the aforementioned wires entering the storage chambers and leakage current detection wires, and the leakage current detection circuit is equivalent to the aforementioned ammeter, power supply, and other structures. However, since the insulating base may have multiple isolated phase electrodes, and the processing is done manually, it is not only inefficient and labor-intensive, but also requires further processing. After completing the withstand voltage breakdown between the phase electrodes, the insulating base must be transferred to another device with a detection electrode and a conductive base plate connected to a leakage current detection circuit for withstand voltage breakdown test between the phase electrodes and ground. The insulating base to be tested is placed on the conductive base plate, the detection electrode is inserted into the phase electrode, and the withstand voltage breakdown performance is judged based on the change in current in the leakage current detection circuit, thus obtaining qualified and doubtful products. Although it can meet the testing requirements, it requires multiple manual transfers, which is inefficient. In addition, each testing process requires a single device, resulting in a large number of devices, large space occupation, and high development costs. Furthermore, manually handling the insulating base to be tested at the high-voltage detection electrode poses a significant safety hazard and is not conducive to the rapid detection of withstand voltage breakdown of the insulating base. Summary of the Invention

[0004] To address the aforementioned problems in existing technologies, this invention aims to provide an insulation seat withstand voltage breakdown testing device. This device comprises an automatic feeding component, a breakdown detection component, a receiving component, and a transfer and unloading component mounted on a frame. The transfer and unloading component is positioned between the automatic feeding component and the breakdown detection component, as well as between the breakdown detection component and the receiving component. This allows for the automatic transfer of insulation seats to be tested from the feeding tray to the breakdown detection component for withstand voltage breakdown testing. After testing, the device automatically unloads and sorts the seats for collection. The testing process eliminates the need for manual transfer, reducing workload and increasing efficiency while also improving safety. Furthermore, the breakdown detection component, by incorporating detection electrodes and a conductive base plate, can simultaneously meet the withstand voltage breakdown performance requirements between phase electrodes and between the phase electrodes and ground within the insulation seat, further enhancing testing efficiency. This allows for multiple tests on a single device, avoiding the problems of numerous devices, large space requirements, and high development costs, thus facilitating rapid detection of withstand voltage breakdown in insulation seats.

[0016] The aforementioned insulation seat withstand voltage breakdown testing equipment includes a second feeding drive component comprising a second slide rail, a second slider, a second slide plate, a second vertical guide rail, a second vertical slider, a vertical support plate, a second moving driver, and a second vertical lifting driver.

[0034] To make the technical means, creative features, objectives, and effects of this invention easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 9 The technical solutions provided by this invention are described in detail, but the following content is not intended to limit this invention.

[0035] Figure 1 This is a structural diagram of an embodiment of the insulating seat withstand voltage breakdown testing device of the present invention; Figure 2 This is a structural diagram of the insulating base withstand voltage breakdown testing device of the present invention after removing the outer cover. Figure 1 and Figure 2As shown, the insulation seat withstand voltage breakdown testing equipment provided in this embodiment includes: a frame 1, an automatic feeding component 2, a breakdown detection component 3, a receiving component 4, and a transfer and unloading component 5. By setting the automatic feeding component 2, the breakdown detection component 3, the receiving component 4, and the transfer and unloading component 5 on the frame 1, the automatic feeding component 2 transports the insulation seat to be tested to the side of the breakdown detection component 3, and then the transfer and unloading component 5 transfers it to the breakdown detection component 3 for withstand voltage breakdown testing. After the test is completed, the transfer and unloading component 5 transports it to the receiving component 4, completing the automatic testing operation without manual intervention, reducing labor burden and improving processing efficiency.

[0036] Figure 3 This is a structural diagram of an automatic feeding assembly according to a preferred embodiment of the present invention. Figures 1 to 3 As shown, the automatic feeding assembly 2 is located at one end of the frame 1. The automatic feeding assembly 2 includes a tray 22 and a feeding transfer section 21. The feeding transfer section 21 includes a first feeding drive 211 and a second feeding drive 212. The first feeding drive 211 and the second feeding drive 212 are arranged parallel to each other on the frame 1, enabling them to move in the same direction. This provides the conditions for subsequently transferring the insulating base to be tested from the same feeding position to the same position next to the breakdown detection assembly 3. Furthermore, each of the first feeding drive 211 and the second feeding drive 212 is provided with a tray 22 equipped with several discharge slots 221. The discharge slots 221 on the tray 22 are used to place the insulating base to be processed, thus defining the position and orientation of the insulating base to be processed, which is beneficial for the subsequent gripping by the transfer and unloading assembly 5.

[0037] Figure 4 This is a structural diagram of a breakdown detection component according to a preferred embodiment of the present invention. Figure 1 , Figure 2 as well as Figure 4As shown, the breakdown detection component 3 is mounted on the frame 1 and located beside the automatic feeding component 2, allowing the insulation seats to be tested, transported by the automatic feeding component 2, to be smoothly transferred to the breakdown detection component 3. The breakdown detection component 3 includes a detection guide rail 31, a conductive base plate 32, a detection driver 33, a lifting frame 34, and detection electrodes 35. The detection guide rail 31 and the detection driver 33 are both mounted on the frame 1. The conductive base plate 32 is slidably mounted on the detection guide rail 31 and is poweredly connected to the drive shaft of the detection driver 33, allowing the detection driver 33 to push the conductive base plate 32 to slide on the detection guide rail 31. Simultaneously, several detection slots 321 are formed on the conductive base plate 32, through which the insulation seats to be tested are placed, ensuring the stability and positional accuracy of the insulation seats during testing. Meanwhile, the lifting frame 34 is set on the frame 1 and located at the end of the detection guide rail 31. The detection electrode 35 is installed on the lifting frame 34 and suspended above the detection guide rail 31. That is, when the detection driver 33 pushes the conductive base plate 32 to the end of the detection guide rail 31 where the lifting frame 34 is located, the lifting frame 34 moves down, so that the detection electrode 35 can be inserted into and contact the phase electrode on the insulating seat. When the detection electrode 35 is energized, the withstand voltage test between two adjacent phase electrodes on the insulating seat can be realized. In addition, when the detection electrode 35 is energized, after the conductive base plate 32 is grounded, the withstand voltage test between the phase electrode on the insulating seat and the ground can be realized. Thus, a single device can meet the needs of both withstand voltage testing between adjacent phase electrodes on the insulating seat and withstand voltage testing between the phase electrode on the insulating seat and the ground. This avoids the problems of needing to set up corresponding detection equipment separately, resulting in a large number of devices, large space occupation, and high development costs. The structural design is more reasonable. It is worth noting that the detection driver 33 includes, but is not limited to, a cylinder, and the lifting frame 34 can be a structure of a guide rail slider combined with a telescopic cylinder commonly used in the market, as long as it can meet the lifting requirements. Its specific structure will not be described in detail here.

[0038] Specifically, such as Figure 1 and Figure 2As shown, the receiving component 4 is mounted on the frame 1 and located on the side of the breakdown detection component 3 opposite to the automatic feeding component 2. That is, after the insulation seat is subjected to withstand voltage testing, the tested insulation seat will be collected. At this time, the receiving component 4 includes a suspicious item collection box and a qualified item collection component 41. A suspicious item recovery port 11 is opened on the frame 1, and the suspicious item collection box is located below the suspicious item recovery port 11. That is, if the product is judged to be suspicious during the withstand voltage test, the product will fall into the suspicious item collection box through the suspicious item recovery port 11 when it is unloaded. If the product is judged to be qualified during the withstand voltage test, the product will be transported to the qualified item collection component 41. At this time, the qualified product collection component 41 includes a conveyor belt 411 and a receiving box 412. The conveyor belt 411 is set on the frame 1 and located on the side of the suspicious product collection port 11 away from the breakdown detection component 3. The receiving box 412 is set at one end of the conveyor belt 411. That is, when the product is determined to be qualified during the withstand voltage test, the product is transferred to the conveyor belt 411 by the transfer and unloading component 5 and transported to the receiving box 412 placed outside the frame 1 through the conveyor belt 411. This realizes the classification and collection of suspicious products and qualified products, and meets the production requirements of automatic unloading.

[0039] Figure 5 This is a structural diagram of a preferred embodiment of the transfer and unloading assembly of the present invention. Figure 1 , Figure 2 as well as Figure 5As shown, the transfer and unloading assembly 5 includes a horizontal moving frame 51, a vertical moving frame 52, a rotating component 53, and a gripper 54. The horizontal moving frame 51 is placed horizontally above the frame 1 and connected in series with the automatic feeding assembly 2, the breakdown detection assembly 3, and the receiving assembly 4. That is, the transfer and unloading assembly 5 can serve as a transfer structure between the automatic feeding assembly 2 and the breakdown detection assembly 3, and also as a transfer structure between the breakdown detection assembly 3 and the receiving assembly 4, thereby meeting the transfer requirements of the insulating seat between the automatic feeding assembly 2, the breakdown detection assembly 3, and the receiving assembly 4. At this time, the vertical moving frame 52 is slidably mounted on the horizontal moving frame 51, so that the vertical moving frame 52 can reciprocate along the vertical moving frame 52 in the horizontal direction. At the same time, the rotating component 53 is installed on the vertical moving frame 52, so that the rotating component 53 can not only reciprocate in the horizontal plane, but also move up and down in the vertical direction under the action of the vertical moving frame 52, and can also rotate in the horizontal plane. In addition, the rotating component 53 is arranged vertically downward, and the gripper 54 is installed on the rotating component 53, realizing the movement and rotation of the gripper 54 in the horizontal plane, and also realizing the up and down movement in the vertical plane, thus making the gripper 54 more flexible and easier to grasp and transfer the insulating seat. It is worth noting that the horizontal moving frame 51 can be a commonly used synchronous belt linear module slide, the vertical moving frame 52 can be a commonly used lead screw nut slide combined with a rotary motor linear drive structure, the rotating part 53 can be a rotary motor or a rotary cylinder, and the gripper 54 can be a pneumatic gripper 54. As long as it meets the usage requirements, and the structure is a commonly used structure in the drive field, its specific structure will not be described in detail here.

[0040] Figure 6 This is a structural diagram of a marking component according to a preferred embodiment of the present invention. Figure 1 , Figure 2 as well as Figure 6 As shown, a marking assembly 6 is also provided on the frame 1. This marking assembly 6 includes a marking platform 61 and a marking machine 62. The marking platform 61 is positioned on the frame 1 and horizontally above the end of the conveyor belt 411 opposite to the end where the receiving box 412 is located. That is, before the transfer and unloading assembly 5 transfers the qualified insulating bases onto the conveyor belt 411, they can be placed on the marking platform 61. The marking machine 62 is positioned on the frame 1 with its marking head facing the marking platform 61. The marking machine 62 then marks the insulating bases placed on the marking platform 61, marking information such as the model number on the qualified products. It is worth noting that the marking machine 62 is a laser marking machine, which is easy to operate, has high marking accuracy, and is suitable for marking the needs of most materials.

[0041] More specifically, a sliding stage 63 is also provided between the marking machine 62 and the frame 1. In this case, the sliding stage 63 includes a marking slide rail 631, a marking slider 632, a marking slide plate 633, and a marking drive assembly 634. The marking slide rail 631 is installed on the frame 1, and the marking slider 632 is slidably mounted on the marking slide rail 631, realizing the reciprocating movement of the marking slider 632 on the marking slide rail 631. At the same time, the marking slide plate 633 is installed on the marking slider 632, realizing the movement of the marking slide plate 633 following the marking slider 632. Furthermore, the marking machine 62 is installed on the marking slide plate 633, and the marking drive assembly 634 is installed on the frame 1 with the drive unit connected to the marking slide plate 633. That is, the marking drive pushes the marking slide plate 633 to reciprocate along the arrangement direction of the marking slide rail 631, thereby realizing the movement of the marking machine 62 and meeting the marking requirements. It is worth noting that the marking drive assembly 634 includes, but is not limited to, a telescopic cylinder, which is sufficient to meet the requirements of linear repetitive motion; its specific structure will not be described in detail here. Furthermore, to further enhance adjustment flexibility, a lifting platform is also provided on the marking slide plate 633. The marking machine 62 is mounted on the lifting platform, meaning that the marking machine 62 can meet both horizontal and vertical movement requirements, making adjustment more convenient. In this case, the lifting platform can be a commercially available linear movement structure using a lead screw and bolt, which is a conventional adjustment structure; therefore, its specific structure will not be described in detail here.

[0042] More specifically, the marking platform 61 includes a stand 611, a marking rotary driver 612, a flipping plate 613, and a clamp. The stand 611 is vertically mounted on the frame 1 and located beside the conveyor belt 411. The lower end of the stand 611 is fixed to the frame 1, and the marking rotary driver 612 is mounted on the upper end of the stand 611. One end of the flipping plate 613 is mounted on the drive shaft of the marking rotary driver 612, and the other end of the flipping plate 613 extends to a position horizontally above the conveyor belt 411, so that the marking rotary driver 612 can drive the flipping plate 613 to flip above the conveyor belt 411, thereby satisfying the requirement of automatic unloading by flipping down the marked insulating seat onto the conveyor belt 411. Furthermore, the fixture is mounted on the flip plate 613, and the fixture and the flip plate 613 are detachably mounted. This not only satisfies the clamping of the insulating seat and ensures the stability of the insulating seat during marking, but also allows for easy replacement of the fixture according to different types of insulating seats, resulting in a more reasonable structural design. It is worth noting that the marking rotary driver 612 can be a rotary motor or a rotary cylinder, as long as it meets the requirements for rotation.

[0043] Figure 7 This is a structural diagram of the first feeding drive component according to a preferred embodiment of the present invention. Figure 3 and Figure 7As shown, the first feeding drive unit 211 includes a first platform 2111, a first slide rail 2112, a first slider 2113, and a first motion driver 2114. At this time, the first platform 2111 is horizontally mounted on the frame 1, and the first slide rails 2112 are respectively provided on both sides of the first platform 2111. The first slider 2113 is slidably mounted on each of the first slide rails 2112, so that the first slider 2113 can reciprocate on its respective first slide rail 2112. In addition, the first motion driver 2114 is arranged parallel to the first slide rails 2112 on the frame 1 and located at the bottom of the first platform 2111, so that the driving direction of the first motion driver 2114 is consistent with the movement direction of the first slide rail 2112, which provides the conditions for the first slider 2113 to move on the first slide rail 2112 by the first motion driver 2114. Furthermore, the first motion driver 2114 passes through the first platform 2111 via the first connecting plate 2115 and connects to a first slider 2113. This means the first motion driver 2114 and the first slider 2113 are connected via the first connecting plate 2115, providing power for the movement of the first slider 2113 and also concealing the power system beneath the first platform 2111. Additionally, both ends of the tray 22 are respectively mounted on the two first sliders 2113, thus supporting both ends of the tray 22 and enabling its reciprocating movement along the first slide rail 2112. It is worth noting that the first motion driver 2114 includes, but is not limited to, commonly used synchronous belt linear module slides, as long as it meets the motion requirement of reciprocating movement in one direction; its specific structure will not be elaborated here.

[0044] Figure 8 This is a structural diagram of the second feeding drive component according to a preferred embodiment of the present invention. Figure 2 , Figure 3 as well as Figure 8As shown, the second feeding drive unit 212 further includes a second slide rail 2121, a second slider 2122, a second slide plate 2123, a second vertical guide rail 2124, a second vertical slider 2125, a vertical tray, a second moving drive 2126, and a second vertical lifting drive 2127. The second slide rail 2121 is positioned on the frame 1 and at the bottom of the first platform 2111, achieving separate arrangement of the second slide rail 2121 and the first slide rail 2112, avoiding mutual interference. Simultaneously, the second slider 2122 slides on the second slide rail 2121, and the second slide plate 2123 is positioned below the first platform 2111 and mounted on the second slider 2122, achieving mutual avoidance between the second slide plate 2123, the first slider 2113 of the first slide rail 2112, and the tray 22 mounted on the first slider 2113, thus avoiding motion interference. Furthermore, the second motion actuator 2126 is arranged parallel to the second slide rail 2121 and located below the first platform 2111. Simultaneously, the second motion actuator 2126 is connected to the second slide plate 2123, enabling the second motion actuator 2126 to drive the second slide plate 2123 to reciprocate along the length of the second slide rail 2121. Furthermore, the second vertical slider 2125 is fixedly mounted on the second slide plate 2123, and the second vertical guide rail 2124 is slidably mounted on the second vertical slider 2125. The upper end of the second vertical guide rail 2124 passes through the first platform 2111 and is fitted with a vertical support plate, i.e., the vertical tray 22 is located above the first platform 2111. The vertical support plate can be vertically adjusted via the second vertical guide rail 2124 and the second vertical slider 2125. Furthermore, the vertical support plate is located between the two first slide rails 2112. Simultaneously, a second vertical lifting actuator 2127 is installed on the second slide plate 2123 and below the first platform 2111. The telescopic shaft of the second vertical lifting actuator 2127 passes through the first platform 2111 and connects to the vertical support plate. That is, the second moving actuator 2126 drives the second slide plate 2123 to reciprocate below the first platform 2111 along the arrangement direction of the second slide rail 2121. At the same time, the second vertical telescopic actuator can also drive the vertical... The vertical support plate moves up and down in the vertical direction, thus satisfying the movement of the vertical support plate in the horizontal and vertical planes. Furthermore, a tray 22 is provided on the vertical support plate, which realizes the movement of the tray 22 on the vertical support plate in both horizontal and vertical directions, thereby avoiding the tray 22 installed on the first slider 2113. This allows the first feeding drive 211 and the second feeding drive 212 to be arranged in the same position on the frame 1, saving installation space while ensuring the normal operation of the two trays 22, and making the structural design more reasonable.It is worth noting that the second motion driver 2126 includes, but is not limited to, the synchronous belt linear module slide commonly used in the market, as long as it can meet the motion requirements of reciprocating movement in one direction. At the same time, the second vertical telescopic driver includes, but is not limited to, a telescopic cylinder, as long as it can meet the linear telescopic movement. Therefore, its specific structure will not be described in detail here.

[0045] More specifically, an insulating plate 36 is provided between the detection guide rail 31 and the conductive base plate 32, so that the conductive base plate 32 can serve as a conductive structure during detection. At this time, a detection support plate 37 is provided at the bottom of the insulating plate 36, and a detection slider 38 is installed at the bottom of the detection support plate 37. The detection slider 38 slides on the detection guide rail 31, that is, the movement of the conductive base plate 32 on the detection guide rail 31 is realized by the detection slider 38 and the detection support plate 37. At the same time, the drive shaft of the detection driver 33 is connected to the detection support plate 37, that is, the detection driver 33 drives the conductive base plate 32 to move through the detection support plate 37, thereby reciprocating between the transfer and unloading assembly 5 and the lifting frame 34 with the detection electrode 35 to meet the detection requirements. At this time, the conductive base plate 32 is grounded through a wire. After the insulating seat to be tested is placed on the conductive base plate 32, the detection driver 33 pushes the conductive base plate 32 to move toward the lifting frame 34 and to move it below the detection electrode 35 on the lifting frame 34. Then, the lifting frame 34 is controlled to move down, so that the detection electrode 35 is inserted into each phase electrode on the insulating seat to be tested and makes contact. Subsequently, each detection electrode 35 is energized to realize the withstand voltage test of each phase electrode to ground.

[0046] It is worth noting that a lifting frame 34 is provided at each end of the detection guide rail 31, and each lifting frame 34 is equipped with a detection electrode 35. That is, there are two sets of detection electrodes 35 corresponding to the same detection guide rail 31, which improves detection efficiency. At the same time, each lifting frame 34 corresponds to a conductive base plate 32 and a detection driver 33. The detection driver 33 is mounted on the frame 1 and connected to the corresponding conductive base plate 32. That is, each set of detection electrodes 35 corresponds to the conductive base plate 32, detection driver 33 and other structures, ensuring that there are two sets of detection structures corresponding to the same detection guide rail 31, thus improving detection efficiency.

[0047] Figure 9 This is a schematic diagram illustrating the installation of the detection electrode and the lifting frame according to a preferred embodiment of the present invention. Figure 2 , Figure 9As shown, a conductive mounting plate 39 is provided between the detection electrode 35 and the lifting frame 34. Several sets of detection electrodes 35 are mounted on the conductive mounting plate 39, meaning that all detection electrodes 35 directly mounted on the conductive mounting plate 39 are electrically connected. This means that only a wire needs to be connected to the conductive mounting plate 39 to supply power to all the detection electrodes 35 directly mounted on it, making wiring more convenient. In this case, one set of detection electrodes 35 corresponds to one detection slot 321, realizing the detection of one insulating base by one set of detection electrodes 35. Furthermore, each group of detection electrodes 35 includes several detection needles 351, and at least one of the detection needles 351 in the same group is covered with an insulating sleeve 352 and is mounted on the conductive mounting plate 39 through the insulating sleeve 352. That is, this detection needle 351 is isolated from the conductive mounting plate 39 through the insulating sleeve 352, while the other detection needles 351 are directly connected to the conductive mounting plate 39. In other words, this detection needle 351 can conduct electricity separately from the other detection needles 351 in the same group. At the same time, the conductive mounting plate 39 and the detection needles 351 covered with insulating sleeves 352 are respectively connected to the detection electrode via wires. When testing the withstand voltage breakdown between phase electrodes on the insulating base, the two poles of the circuit can be reasonably selected to conduct the test. For example, when testing the insulating base used for three-phase electrical connection, the test needle 351 with the insulating sleeve 352 can be set to correspond to the V phase phase electrode on the insulating base, while the U phase and W phase phase electrodes correspond to other test needles 351 in the same group. When the test needle 351 with the insulating sleeve 352 is energized and the other test needles 351 are not energized, the phase withstand voltage between the V phase and the U phase and W phase respectively can be detected, which meets the withstand voltage breakdown test requirements between adjacent phase electrodes on the insulating base.

[0048] More specifically, a controller is also installed on the frame 1. At this time, the automatic feeding component 2, the breakdown detection component 3, the receiving component 4, the marking component 6, and the transfer and unloading component 5 are all electrically connected to the controller. The controller controls the automatic operation of the automatic feeding component 2, the breakdown detection component 3, the receiving component 4, the marking component 6, and the transfer and unloading component 5. That is, after the feeding is completed, the transfer and unloading component 5 automatically transfers the insulation seat to be tested to the breakdown detection component 3. Then, the breakdown detection component 3 automatically performs a withstand voltage breakdown test on the insulation seat to be tested. The controller then controls the transfer and unloading component 5 to transfer the suspicious products and qualified products to the receiving component 4 and the marking component 6, respectively. The controller then controls the marking component 6 to automatically mark the qualified products and generate the product and its corresponding data for quick product information acquisition and convenient subsequent product traceability. Finally, the controller controls the transfer and unloading component 5 to automatically transfer the marked insulation seat to the corresponding receiving component 4 to complete the testing requirements. Furthermore, the controller has a storage module that stores the data generated by the breakdown detection component 3 and the marking component 6. The controller also has a human-machine interaction module, such as a touch screen, which makes it convenient for users to obtain product testing information and facilitates subsequent product traceability. The structural design is more reasonable.

Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
