[0059] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0063] like Figure 1-Figure 4 As shown, this embodiment provides a voltage detection device for performing voltage detection on a device to be detected 100. In this embodiment, the device to be detected 100 is a relay and a protective device. In other embodiments, the voltage detection device can also be used for voltage detection of other types of equipment. The voltage detection device includes a detection frame 11, a first guide rail 12, a first slider 13, a detection plate 14, a positioning assembly 15, a second guide rail 16, a second slider 17, a movable plate 18, a first drive assembly 19, and a voltage detector 20. The first guide rail 12 is disposed on the detection frame 11 and extends along a first direction. The first slider 13 is slidably disposed on the first guide rail 12. The detection plate 14 is fixedly disposed on the first slider 13 and is used to support the device to be detected 100. The positioning assembly 15 is disposed on the top surface of the detection plate 14 and is used to clamp the device to be detected 100. The second guide rail 16 is disposed on the detection frame 11 and is located above the first guide rail 12. The second guide rail 16 extends along a second direction perpendicular to the first direction, and the second direction is parallel to the top surface of the detection plate 14. The second slide block 17 is slidably arranged on the second guide rail 16. The movable plate 18 is fixedly arranged on the second slide block 17. The first driving assembly 19 includes a cylinder 191 and a mounting plate 192, the cylinder 191 being fixedly arranged on the movable plate 18, and the mounting plate 192 being fixedly arranged on the telescopic rod of the cylinder 191. The voltage detector 20 is fixedly arranged on the mounting plate 192, and the voltage detector 20 is used to detect the device to be detected 100. The voltage detector 20 is located above the detection plate 14. The cylinder 191 can drive the mounting plate 192 to move along the third direction so that the voltage detector 20 is close to or away from the detection plate 14, and the first direction and the second direction are both perpendicular to the third direction. In the present embodiment, the first direction is the length direction of the detection frame 11, the second direction is the width direction of the detection frame 11, and the third direction is the height direction of the detection frame 11. When the detection frame 11 is placed on a horizontal plane, the first direction and the second direction are both along the horizontal direction, and the third direction is along the vertical direction.

[0064] In the voltage detection device provided in this embodiment, the cylinder 191 of the first driving component 19 can drive the mounting plate 192 on which the voltage detector 20 is installed to move along the third direction, so that the voltage detector 20 is close to or away from the detection plate 14, so as to detect the device to be detected 100 on the detection plate 14. In addition, in this embodiment, the first guide rail 12 extends along the first direction, and the detection plate 14 is arranged on the first slider 13 on the first guide rail 12, so that the device to be detected 100 arranged on the detection plate 14 can move relative to the detection frame 11 along the first direction. The second guide rail 16 is located above the first guide rail 12, and the second guide rail 16 extends along the second direction. The movable plate 18 is arranged on the second slider 17 on the second guide rail 16, so that the movable plate 18 located above the first guide rail 12 can move relative to the detection frame 11 along the second direction. The first direction, the second direction, and the third direction are perpendicular to each other, so that by moving the voltage detector 20 along the second direction and moving the device to be detected 100 along the first direction, in conjunction with the movement of the voltage detector 20 along the third direction, the voltage detector 20 can detect line ports at different positions on the device to be detected 100. This eliminates the step of the staff placing the device to be detected 100 multiple times during the detection process, thereby saving detection time and improving detection efficiency.

[0065] Furthermore, if Figure 1-Figure 3 As shown, two first guide rails 12 are provided, and the two first guide rails 12 are spaced apart along the second direction. Each first guide rail 12 is provided with two first sliders 13, and the four first sliders 13 are fixedly connected to the detection plate 14. The two first guide rails 12 and the four first sliders 13 can better support and guide the detection plate 14, preventing the detection plate 14 from shaking during the detection process.

[0066] Furthermore, if Figure 1-Figure 3 As shown, two second guide rails 16 are provided, and the two second guide rails 16 are spaced apart along the third direction. Each second guide rail 16 is provided with two second sliders 17, and the four second sliders 17 are fixedly connected to the movable plate 18. The two first guide rails 12 and the four first sliders 13 can better support and guide the movable plate 18, preventing the movable plate 18 from shaking during the inspection process.

[0067] Alternatively, as Figure 1-Figure 3As shown, the voltage detection device provided in this embodiment further includes a second drive assembly 21 and a third drive assembly 22. The second drive assembly 21 is disposed on the detection frame 11 and is used to drive the detection plate 14 to move along the first guide rail 12. The third drive assembly 22 is disposed on the detection frame 11 and is used to drive the movable plate 18 to move along the second guide rail 16. By providing the second drive assembly 21 to drive the detection plate 14 and the third drive assembly 22 to drive the movable plate 18, automatic control of the movement process of the detection plate 14 and the movable plate 18 is facilitated, thereby facilitating precise control of the movement distance of the detection plate 14 and the movable plate 18.

[0068] Furthermore, if Figure 1-Figure 3 As shown, the second drive assembly 21 includes a first motor 211, a first screw 212, and a first rotation block 213. The first motor 211 is fixedly mounted on the detection frame 11. The first screw 212 is rotatably mounted on the detection frame 11 and extends in a first direction. The first motor 211 is used to drive the first screw 212 to rotate relative to the detection frame 11. The first rotation block 213 is sleeved on the first screw 212 and is threadedly connected to the first screw 212. The detection plate 14 is fixedly connected to the first rotation block 213. The first motor 211 drives the first screw 212 to rotate relative to the detection frame 11. Since the first rotating block 213 is fixedly connected to the detection plate 14, the first rotating block 213 can only move in the first direction relative to the detection frame 11, but cannot rotate relative to the detection frame 11. Therefore, the rotation of the first screw 212 can be converted into the movement of the first rotating block 213 in the first direction, so that the first motor 211 can drive the detection plate 14 to move in the first direction relative to the detection frame 11 through the first rotating block 213. The connection between the first motor 211 and the first screw 212, and the rotational connection between the first screw 212 and the detection frame 11 are both common knowledge in the art and will not be described in detail here.

[0069] Furthermore, if Figure 1-Figure 3As shown, the third drive assembly 22 includes a second motor 221, a second screw 222, and a second rotation block 223. The second motor 221 is fixedly mounted on the detection frame 11. The second screw 222 is rotatably mounted on the detection frame 11 and extends in a second direction. The second motor 221 is used to drive the second screw 222 to rotate relative to the detection frame 11. The second rotation block 223 is sleeved on the second screw 222 and threadedly connected to the second screw 222. The movable plate 18 is fixedly connected to the second rotation block 223. The second motor 221 drives the second screw 222 to rotate relative to the detection frame 11. Since the second rotating block 223 is fixedly connected to the movable plate 18, the second rotating block 223 can only move in the second direction relative to the detection frame 11 and cannot rotate relative to the detection frame 11. Therefore, the rotation of the second screw 222 can be converted into the movement of the second rotating block 223 in the second direction, so that the second motor 221 can drive the movable plate 18 to move in the second direction relative to the detection frame 11 via the second rotating block 223. The connection between the second motor 221 and the second screw 222, and the rotational connection between the second screw 222 and the detection frame 11 are both common knowledge in the art and will not be described in detail here.

[0070] Specifically, when the voltage detection device is in use, the first motor 211 is started in forward rotation mode, and the detection plate 14 can be driven to move away from the first motor 211 by the first screw 212. The first motor 211 is started in reverse mode, and the detection plate 14 can be moved closer to the first motor 211, thereby realizing the horizontal displacement of the detection plate 14. The second motor 221 is started in forward rotation mode, and the movable plate 18 is driven to move away from the second motor 221 by the second screw 222. The second motor 221 is started in reverse mode, and the movable plate 18 can be moved closer to the second motor 221, thereby realizing the horizontal displacement of the movable plate 18. Through the movement of the movable plate 18 and the detection plate 14, the detection plate 14 can be moved to directly below the voltage detector 20, so that the device to be detected 100 is vertically corresponding to the voltage detector 20.

[0071] Alternatively, as Figure 1-Figure 4As shown, the positioning assembly 15 includes two relatively arranged clamping mechanisms 151, and the clamping mechanism 151 includes a fixed plate 1511, a sliding rod 1512, a clamping plate 1513 and a spring 1514. The fixed plate 1511 is fixedly arranged on the top surface of the detection plate 14. The sliding rod 1512 is slidably arranged on the fixed plate 1511 and extends along the second direction. The clamping plate 1513 is fixedly arranged at one end of the sliding rod 1512. The spring 1514 is arranged in a one-to-one correspondence with the sliding rod 1512, and the spring 1514 is sleeved on the corresponding sliding rod 1512, and one end abuts against the fixed plate 1511, and the other end abuts against the clamping plate 1513. By clamping the device to be detected 100 by two relatively arranged clamping mechanisms 151, the device to be detected 100 can be fixed. Specifically, when the two clamping mechanisms 151 clamp the device to be tested 100, the spring 1514 of the clamping mechanism 151 is compressed, and the elastic force of the spring 1514 drives the clamping plate 1513 to clamp the device to be tested 100. Specifically, a connecting hole is provided on the fixed plate 1511, and the end of the sliding rod 1512 away from the clamping plate 1513 slides through the connecting hole.

[0072] Furthermore, if Figure 1-Figure 4 As shown, each clamping mechanism 151 includes two sliding rods 1512. Two connecting holes are provided on each fixing plate 1511. The two sliding rods 1512 of the clamping mechanism 151 are spaced apart along the first direction. The clamping plate 1513 of the clamping mechanism 151 is fixedly connected to the two sliding rods 1512 of the clamping mechanism 151. The provision of two sliding rods 1512 enhances the guiding effect of the sliding rods 1512 on the clamping plate 1513, thereby preventing the clamping plate 1513 from shaking.

[0073] Furthermore, if Figure 1 、 Figure 3 and Figure 4 As shown, the top of each clamping plate 1513 is provided with a guiding bevel 15131. The guiding bevels 15131 of the two clamping mechanisms 151 are arranged relative to each other. During detection, the device to be detected 100 is taken, placed between the two clamping plates 1513, and pressed down along the guiding bevels 15131 on the two clamping plates 1513. The downward pressure forces the two clamping plates 1513 to compress the spring 1514, so that the device to be detected 100 is clamped and limited by the two clamping plates 1513. This setting can play a limiting role in the device to be detected 100, realize the positioning of the positioning component 15 on the device to be detected 100 along the second direction, avoid the displacement of the device to be detected 100 when the detection plate 14 moves, affect the normal detection, and facilitate the use of the voltage detection device.

[0074] Furthermore, if Figure 1 、 Figure 3 and Figure 4As shown, the positioning assembly 15 also includes a positioning rod 152 fixedly mounted on the top surface of the detection plate 14. The positioning rod 152 extends in the second direction and is configured to abut against the side of the device to be detected 100. When the device to be detected 100 is placed, one side of the device to be detected 100 abuts the positioning rod 152, thereby enabling the positioning assembly 15 to position the device to be detected 100 along the first direction. Through the clamping of the two clamping mechanisms 151 and the abutment of the positioning rod 152, the position of the device to be detected 100 on the detection plate 14 is uniquely determined after it is fixed, facilitating detection of the device to be detected 100 by the voltage detector 20.

[0075] Alternatively, as Figure 1-Figure 3 As shown, the detection frame 11 includes two first support rods 111, two second support rods 112, two third support rods 113 and a fourth support rod 114. The two first support rods 111 are arranged at intervals along the first direction and both extend along the second direction. The two second support rods 112 are arranged at intervals along the second direction and both extend along the first direction. The two first guide rails 12 are respectively arranged on the two second support rods 112. The two second support rods 112 are both fixed on the two first support rods 111. The two third support rods 113 are arranged at intervals along the second direction. The bottom ends of the two third support rods 113 are respectively fixed on the two ends of a first support rod 111. The two third support rods 113 extend along the third direction. The two ends of the fourth support rod 114 are respectively fixed on the top ends of the two third support rods 113. The fourth support rod 114 extends along the second direction. The two second guide rails 16 are both fixed on the fourth support rod 114.

[0076] The working process of this utility model is:

[0077] During testing, the device to be tested 100 is taken and pressed down along the two guide inclined surfaces 15131. The downward pressure forces the two clamping plates 1513 to move, so that the device to be tested 100 is squeezed and limited by the two clamping plates 1513. This setting can limit the device to be tested 100, preventing the device to be tested 100 from being displaced when the testing plate 14 moves, which would affect normal testing, and facilitates the use of the voltage detection device.

[0078] Then, the first motor 211 is started in reverse mode to move the detection plate 14 toward the first motor 211. When the first circuit port of the device to be detected 100 moves to the detection position, the first motor 211 stops and the second motor 221 is started to move the voltage detector 20 to the top of the first circuit port of the device to be detected 100. The cylinder 191 is started and the voltage detector 20 moves down to the first circuit port of the device to be detected 100, thereby realizing the detection of the first circuit port of the device to be detected 100. By repeating the above process, the detection of each circuit port on the device to be detected 100 can be realized. The entire detection process only requires fixing the device to be detected 100 once.

[0079] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
