The detection device includes: a support bracket for placing the electrically conductive workpiece; a first testing module including a first push-pull motor, a first support plate, and a first electrode. The first support plate is fixed to the first push-pull motor, which drives the first support plate closer to or further away from the electrically conductive workpiece. The first electrode is connected to a power source, with one end of the first electrode disposed on the first support plate and the other end for contacting the electrical testing point. A first lateral probe is disposed at the end of the first electrode closest to the workpiece, and a non-zero angle exists between the first lateral probe and the first electrode for contacting the electrical testing point; a second testing module including a fixed post and multiple second electrodes, all disposed on the fixed post, for contacting their respective electrical testing points; and a control module, with the first and second testing modules electrically connected to the control module, which identifies the electrical conductivity status of the first and second electrodes.

[0006] In some embodiments, the first test module further includes a first insulating protective sleeve, the interior of which is hollow, and at least a portion of the first electrode is fitted inside the first insulating protective sleeve.

[0007] In some embodiments, the first test module further includes a first rotary motor, the fixed end of the first rotary motor is fixed to the first support plate, and the rotating end of the first rotary motor is connected to the end of the first electrode near the first support plate. The first rotary motor is used to drive the first electrode to rotate so that the first lateral probe rotates around the first electrode.

[0008] In some embodiments, the second test module further includes a second push-pull motor, the movable end of which is connected to the fixed column, and the second push-pull motor is used to drive the second electrode closer to or away from the energized workpiece.

[0009] In some embodiments, a high-voltage protection module is also included, wherein the power supply, the first electrode, and the second electrode are respectively connected to the high-voltage protection module.

[0010] In some embodiments, a third testing module is further included. The third testing module includes a third push-pull motor, a second support plate, and a third electrode. The second support plate is connected to the movable end of the third push-pull motor. The traveling direction of the third push-pull motor is perpendicular to the traveling direction of the first push-pull motor. The third electrode is disposed on the second support plate. The third push-pull motor is used to drive the third electrode to approach or move away from the energized workpiece. The third electrode is used to contact the measuring part.

[0011] In some embodiments, the third test module further includes a second insulating protective sleeve, the second insulating protective sleeve being hollow inside, and the third electrode being sleeved inside the second insulating protective sleeve.

[0012] In some embodiments, the third test module further includes a second rotary motor, the fixed end of the second rotary motor is disposed on the second support plate, the end of the third electrode away from the energized workpiece is disposed on the movable end of the second rotary motor, and the end of the third electrode close to the energized workpiece is provided with a second lateral probe, and there is a non-zero included angle between the second lateral probe and the third electrode.

[0013] In some embodiments, the first test module further includes a distance measuring instrument, which is disposed on the first support plate. The distance measuring direction of the distance measuring instrument is the same as the travel direction of the first push-pull motor. The distance measuring instrument is used to detect the distance between the first support plate and the energized workpiece.

[0014] The embodiments of this application include at least the following beneficial effects: By setting a support bracket, the support bracket provides a stable support platform for the energized workpiece, ensuring that the position of the workpiece is fixed during the testing process and avoiding the impact of workpiece movement on the testing results; after the workpiece is stably placed on the support bracket after being powered on, a first testing module is set up. The first testing module includes a first push-pull motor and a first support plate. A first electrode is set on the first support plate. The first push-pull motor pushes the first support plate toward the energized workpiece, so that the first electrode contacts the measuring part on the energized workpiece. At the same time, a first lateral probe is set at the end of the first electrode, thereby increasing the angle between the first lateral probe and the first electrode to be non-zero. Therefore, in the first push-pull motor, the first electrode is pushed toward the energized workpiece. During the process of the motor pushing the first support plate, for electrical measuring parts where the angle between the contact plane and the direction of travel of the first support plate is less than 90 degrees or even parallel or nearly parallel, the contact area between the end of the first lateral probe and the electrical measuring part is small. This reduces the friction area of ​​the first lateral probe on the electrical measuring part, reduces the wear of the electrical measuring part, and allows the first lateral probe to contact the electrical measuring part more flexibly and accurately for testing. By adjusting the thrust of the first motor, the contact force between the first lateral probe and the electrical measuring part can be increased, making the contact between the first lateral probe and the electrical measuring part more solid, reducing the resistance between the first lateral probe and the electrical measuring part, and improving the efficiency and accuracy of electrical measurement.

[0022] Currently, testing the circuit performance of sensors is a crucial step in the sensor manufacturing process. Under existing technology, delicate sensors often have electrically conductive parts that are difficult to access. However, current electrical conductivity detection devices are generally large and lack flexibility, making it difficult to achieve effective contact with these conductive parts in practice.

[0023] To address the problem of difficulty in achieving effective contact with certain energized parts, this invention provides a detection device for energized workpieces, comprising: The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] Reference Figures 1 to 4 This utility model provides a detection device for an electrically conductive workpiece. The workpiece has multiple electrical testing points, and the detection device is used to detect the electrical conductivity between these testing points. The detection device includes: Support bracket 100 is used to place electrically powered workpieces; The first test module 200 includes a first push-pull motor 210, a first support plate 220, and a first electrode 230. The first support plate 220 is fixed on the first push-pull motor 210. The first push-pull motor 210 is used to drive the first support plate 220 to move closer to or away from the energized workpiece. The first electrode 230 is connected to a power source. One end of the first electrode 230 is disposed on the first support plate 220, and the other end of the first electrode 230 is used to contact the measuring part. A first lateral probe 231 is disposed at the end of the first electrode 230 that is close to the energized workpiece. There is a non-zero angle between the first lateral probe 231 and the first electrode 230. The first lateral probe 231 is used to contact the measuring part. The second test module 300 includes a fixed post 310 and multiple second electrodes 320. The second electrodes 320 are all disposed on the fixed post 310 and are used to contact the corresponding electrical measurement parts respectively. The control module 400, the first test module 200 and the second test module 300 are electrically connected to the control module 400 respectively. The control module 400 is used to identify the energization status of the first electrode 230 and the second electrode 320.

[0025] Based on this, a support bracket 100 is provided to offer a stable support platform for the energized workpiece, ensuring its position remains fixed during testing and preventing workpiece movement from affecting the test results. After the workpiece is stably placed on the support bracket 100 and powered on, a first test module 200 is installed. The first test module 200 includes a first push-pull motor 210 and a first support plate 220. A first electrode 230 is mounted on the first support plate 220. The first push-pull motor 210 pushes the first support plate 220 toward the energized workpiece, causing the first electrode 230 to contact the measuring part on the workpiece. Simultaneously, a first lateral probe 231 is provided at the end of the first electrode 230, thus increasing the angle between the first lateral probe 231 and the first electrode 230 to be non-zero. During the process of the first push-pull motor 210 pushing the first support plate 220, for electrical measuring parts where the angle between the contact plane and the traveling direction of the first support plate 220 is less than 90 degrees or even parallel or nearly parallel, the contact area between the end of the first lateral probe 231 and the electrical measuring part is small, thereby reducing the friction area of ​​the first lateral probe 231 on the electrical measuring part, reducing the wear of the electrical measuring part, and enabling the first lateral probe 231 to contact the electrical measuring part more flexibly and accurately for testing; by adjusting the thrust of the first traveling motor, the direct contact force between the first lateral probe 231 and the electrical measuring part can be increased, thereby making the contact between the first lateral probe 231 and the electrical measuring part more firm, reducing the resistance between the first lateral probe 231 and the electrical measuring part, and improving the efficiency and accuracy of electrical measurement.

[0026] The first electrode 230 points in the same direction as the first push-pull motor 210. Optionally, the support bracket 100 is located directly below the first test module 200, the energized workpiece is placed above the support bracket 100, the first electrode 230 is located below the first support plate 220, the first electrode 230 is vertically downward, and the first push-pull motor 210 pushes vertically downward, thereby pushing the first electrode 230 and the first lateral probe 231 vertically downward. The second test module 300 is located on the side of the support bracket 100, and the second electrode 320 is located on the fixed column 310 on the side close to the support bracket 100. The second electrode 320 points horizontally towards the support bracket 100.

[0027] In some specific embodiments, a total of four electrical measuring points are provided on the energized workpiece. Two of the electrical measuring points are located at the top, and the other two are located on the side. Each of the electrical measuring points located at the top is connected to one of the electrical measuring points located on the side. The first electrode 230 and the first lateral probe 231 are in contact with the two electrical measuring points located at the top, respectively. Two second electrodes 320 are provided on the fixed column 310, and the two second electrodes 320 are in contact with the electrical measuring points located on the side, respectively. The control module 400 controls the first electrode 230 and the second electrode 320 to be energized, and measures the current and voltage flowing through the first electrode 230 and the second electrode 320, thereby determining whether the path between the electrical measuring points in the energized workpiece can be normally energized.

[0028] In addition, in some embodiments of the present invention, the first test module 200 further includes a first insulating protective sleeve (not shown in the figure), the interior of the first insulating protective sleeve is hollow, and at least a portion of the first electrode 230 is sleeved inside the first insulating protective sleeve.

[0029] In one specific embodiment, the portion of the first electrode 230 near the first support plate 220 and located to the outside is completely covered by the first insulating protective sleeve, while the portion of the first electrode 230 near the energized workpiece is exposed to the outside. The first electrode 230 and the first lateral probe 231 respectively contact the two measuring parts.

[0030] In another specific embodiment, the portion of the first electrode 230 located on the outside is completely covered by the first insulating protective sleeve, and the first lateral probe 231 is exposed to the outside. In this case, only the first lateral probe 231 makes contact with one of the measuring parts.

[0031] Additionally, refer to Figure 2As shown, in some embodiments of the present invention, the first test module 200 further includes a first rotary motor 240. The fixed end of the first rotary motor 240 is fixed on the first support plate 220, and the rotating end of the first rotary motor 240 is connected to the end of the first electrode 230 near the first support plate 220. The first rotary motor 240 is used to drive the first electrode 230 to rotate so that the first lateral probe 231 rotates around the first electrode 230.

[0032] Specifically, the first push-pull motor 210 drives the first support plate 220 to approach the energized workpiece. When the first lateral probe 231 reaches the side of the measuring part, the first rotary motor 240 controls the first electrode 230 to rotate, so that the first lateral probe 231 presses against the measuring part. After the measuring work is completed, the first rotary motor 240 controls the first electrode 230 to rotate in the opposite direction, so that the first lateral probe 231 moves away from the measuring part. Subsequently, the first push-pull motor 210 pulls back the first support plate 220, so that the first electrode 230 moves away from the energized workpiece.

[0033] In one specific embodiment, the second test module 300 further includes a second push-pull motor 330, the movable end of which is connected to the fixed column 310. The second push-pull motor 330 is used to drive the second electrode 320 to approach or move away from the energized workpiece.

[0034] The fixed end of the second push-pull motor 330 is fixed on the first support plate 220. The second test module 300 moves with the first support plate 220. That is, when the support bracket 100 carries the energized workpiece to the bottom of the first test module 200, the first push-pull motor 210 drives the first support plate 220 to move downward. At this time, the first electrode 230 enters the energized workpiece, and the second test module 300 reaches the side of the energized workpiece. Then, the second push-pull motor 330 pushes the fixed post 310 out of the energized workpiece, so that the second electrode 320 enters the energized workpiece and contacts the measuring part. After the measuring work is completed, the second push-pull motor 330 pulls back the fixed post 310 and the second electrode 320. Then, the first push-pull motor 210 drives the first support plate 220 away from the energized workpiece, thereby pulling the first electrode 230 and the second test module 300 upward. The support bracket 100 is withdrawn from the bottom of the first test module 200 and then brings in a new energized workpiece.

[0035] Additionally, refer to Figure 2As shown, in some embodiments of this utility model, the detection device further includes a third test module 600. The third test module 600 includes a third push-pull motor 610, a second support plate 620, and a third electrode 630. The second support plate 620 is connected to the movable end of the third push-pull motor 610. The traveling direction of the third push-pull motor 610 is perpendicular to the traveling direction of the first push-pull motor 210. The third electrode 630 is disposed on the second support plate 620. The third push-pull motor 610 is used to drive the third electrode 630 to approach or move away from the energized workpiece. The third electrode 630 is used to contact the measuring part.

[0036] Optionally, the third test module 600 is disposed on the side of the support bracket 100, the third electrode 630 points towards the energized workpiece, and the first electrode 230, the second electrode 320 and the third electrode 630 are perpendicular to each other. When the support bracket 100 reaches the designated position, the control module 400 drives the first electrode 230 and the third electrode 630 to move towards the energized workpiece and contact the corresponding electrical testing parts through the first push-pull motor 210 and the third push-pull motor 610 respectively. After the electrical testing is completed, the first push-pull motor 210 and the third motor pull the first electrode 230 and the third electrode 630 back respectively.

[0037] Optionally, the third test module 600 also includes a second rotary motor 640, the fixed end of the second rotary motor 640 is disposed on the second support plate 620, the end of the third electrode 630 away from the energized workpiece is disposed on the movable end of the second rotary motor 640, and the end of the third electrode 630 close to the energized workpiece is provided with a second lateral probe, and there is a non-zero included angle between the second lateral probe and the third electrode 630.

[0038] Similar to the first test module 200, the movable end of the third push-pull motor 610 faces the energized workpiece. The third push-pull motor 610 drives the second support plate 620 to move toward the energized workpiece, and the third electrode 630 enters the energized workpiece. The second lateral probe is located on the side of the corresponding electrical testing part. The second rotary motor 640 drives the third electrode 630 to rotate around itself, pressing the second lateral probe toward the electrical testing part. By setting the thrust of the second rotary motor 640, the pressure between the second lateral probe and the electrical testing part can be controlled, thereby ensuring good contact between the second lateral probe and the electrical testing part and reducing the resistance between the second lateral probe and the electrical testing part.

[0039] Optionally, the third test module 600 also includes a second insulating protective sleeve (not shown in the figure), the second insulating protective sleeve is hollow inside, and the third electrode 630 is sleeved inside the second insulating protective sleeve.

[0040] In one specific embodiment, the portion of the third electrode 630 near the second support plate 620 and located to the outside is completely covered by the second insulating protective sleeve, while the portion of the third electrode 630 near the energized workpiece protrudes outward. The third electrode 630 and the second lateral probe respectively contact the two measuring points.

[0041] In another specific embodiment, the portion of the third electrode 630 located on the outside is completely covered by the second insulating protective sleeve, and the second lateral probe is exposed outward. In this case, only the second lateral probe makes contact with one of the measuring parts.

[0042] In addition, in some embodiments of this utility model, the first test module 200 further includes a rangefinder 700 (not shown in the figure). The rangefinder 700 is disposed on the first support plate 220. The measuring direction of the rangefinder 700 is the same as the traveling direction of the first push-pull motor 210. The rangefinder 700 is used to detect the distance between the first support plate 220 and the energized workpiece.

[0043] During the process of the first push-pull motor 210 driving the first support plate 220 to move towards the energized workpiece, the rangefinder 700 continuously detects the distance between the first support plate 220 and the energized workpiece. When the control module 400 determines that the distance between the first support plate 220 and the energized workpiece is less than a preset threshold, the control module 400 stops the first push-pull motor 210 and issues an alarm to notify the staff to make adjustments.

[0044] Optionally, the second test module 300 and the third test module 600 may also be equipped with rangefinders 700. The rangefinders 700 are respectively mounted on the fixed column 310 and the second support plate 620. The measuring direction of the rangefinder 700 on the fixed column 310 is the same as the traveling direction of the fixed column 310. The rangefinder 700 is used to detect the distance between the fixed column 310 and the energized workpiece. The measuring direction of the rangefinder 700 on the second support plate 620 is the same as the traveling direction of the second support plate 620. The rangefinder 700 is used to detect the distance between the second support plate 620 and the energized workpiece. Similarly, when the control module 400 determines that the distance between the second support plate 620 and the energized workpiece is less than a preset threshold, or the distance between the fixed column 310 and the energized workpiece is less than a preset threshold, the control module 400 stops the second push-pull motor 330 and the third push-pull motor 610 and issues an alarm to notify the staff to make adjustments.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments.
