[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

[0024] like Figure 1 An insulation withstand voltage test device 100 is shown, which is mainly used to test photovoltaic modules. The insulation withstand voltage test device 100 includes an equipment frame 11, a first moving component 12 and a test fixture 13. The equipment frame 11 is the basic frame of the insulation withstand voltage test device 100, and the equipment frame 11 is used to provide support and installation points for other components of the insulation withstand voltage test device 100. The first moving component 12 is at least partially arranged on the equipment frame 11, and the test fixture 13 is at least partially arranged on the equipment frame 11 through the first moving component 12, so that the test fixture 13 can be moved relative to the equipment frame 11 through the first moving component 12. Because the test fixture 13 needs a certain amount of time to detect the photovoltaic module, the photovoltaic module needs to be in a stationary state, and the photovoltaic module moves along the assembly line on the production line, resulting in low detection efficiency of the test fixture 13. When the test fixture 13 detects the photovoltaic module, the first moving component 12 can make the test fixture 13 move along with the movement of the photovoltaic module, and the photovoltaic module does not need to be in a static state, thereby improving the detection efficiency of the test fixture 13. In order to clearly explain the technical solution of the present application, the following is also defined: Figure 1 Front, back, left, right, top and bottom shown.

[0025] like Figure 2 and Figure 3As shown, as an embodiment, the first moving component 12 includes a connecting bracket 121, a first moving mechanism 122 that moves linearly along a first direction, and a second moving mechanism 123 that moves linearly along a second direction. The connecting bracket 121 is fixedly connected to the equipment frame 11, and the first direction and the second direction are perpendicular to each other. The first moving mechanism 122 is at least partially located on the connecting bracket 121, and the second moving mechanism 123 is at least partially arranged on the first moving mechanism 122. The test tool 13 is connected to the first moving mechanism 122 through the second moving mechanism 123. The test tool 13 can move along the first direction with the first moving mechanism 122 or move along the second direction with the second moving mechanism 123, that is, the test tool 13 can move in the front and rear directions through the first moving mechanism 122, and the test tool 13 can also move in the up and down directions through the second moving mechanism 123. When the insulation and voltage withstand test equipment 100 tests the photovoltaic module, the photovoltaic module is first transported to the insulation and voltage withstand test equipment 100, and then the first movable component 12 moves downward through the second movable mechanism 123 and drives the test fixture 13 to move downward, so that the test fixture 13 can perform the insulation and voltage withstand test on the photovoltaic module. At the same time, the first movable component 12 moves in the front-to-back direction through the first movable mechanism 122, so that the test fixture 13 can move synchronously with the photovoltaic module in the front-to-back direction; when the insulation and voltage withstand test of the photovoltaic module is completed, the second movable mechanism 123 moves upward to drive the test fixture 13 away from the photovoltaic module, and at the same time, the first movable mechanism 122 moves along the front-to-back direction to return to the initial position before the insulation internal pressure test. Through the above arrangement, the insulation withstand voltage test equipment 100 can perform insulation withstand voltage test on the photovoltaic module through the second moving mechanism 123, and can also move with the photovoltaic module through the first moving mechanism 122 during the test, so that the test fixture 13 and the photovoltaic module are in a relatively static state during the test, so that while meeting the working requirements of the test fixture 13, it is not necessary to keep the photovoltaic module in a static state, thereby improving the test efficiency of the test fixture 13 and the working efficiency of the insulation withstand voltage test equipment 100. It can be understood that the first direction in the embodiment of the present application refers to the front and rear direction of the insulation withstand voltage test equipment 100, and the second direction refers to the up and down direction of the insulation withstand voltage test equipment 100.

[0026] Specifically, the connecting bracket 121 extends in the first direction, and a guide rail slider structure 1211 is provided on the connecting bracket 121, and the guide rail slider structure 1211 also extends in the first direction, and the first moving mechanism 122 is slidably connected with the guide rail slider structure 1211, and a rack structure 1212 is also provided on the connecting bracket 121, and a drive motor 1222 is provided on the first moving mechanism 122, and the drive motor 1222 is connected to the rack structure 1212 through a gear. Through the above-mentioned arrangement, the first moving mechanism 122 moves in the front and rear directions on the connecting bracket 121 by sliding, so as to reduce the vibration of the first moving mechanism 122 during the movement, and avoid affecting the work of the test fixture 13. In addition, through the cooperation of the gear rack, the rotational motion of the drive motor 1222 is converted into the linear motion of the first moving mechanism 122, thereby providing power for the first moving mechanism 122, and the gear rack has a large transmission power and a high transmission accuracy, which is conducive to realizing the movement of the test fixture 13 with the movement of the photovoltaic module. In the present application, the driving motor 1222 may be configured as a servo motor, so as to precisely control the movement of the first moving mechanism 122 .

[0027] In this embodiment, the first moving mechanism 122 includes a mounting frame 1221, which is slidably connected to the guide rail slider structure 1211. The driving motor 1222 is arranged on the mounting frame 1221, and an opening 1221a is arranged on the mounting frame 1221. The driving motor 1222 at least partially passes through the opening 1221a and is connected to the rack structure 1212 through a gear. The guide rail slider structure 1211 of the present application is provided with two guide rails, and the rack structure 1212 is arranged between the two guide rails, so that the driving motor 1222 will not affect the normal operation of the guide rail slider structure 1211 during the process of passing through the opening 1221a and being connected to the rack through the gear. Among them, the second moving mechanism 123 is at least partially arranged on the mounting frame 1221, and the second moving mechanism 123 includes a linear motion module 1231 and a support frame 1232 extending along the second direction, the linear motion module 1231 is at least partially arranged on the mounting frame 1221, the support frame 1232 is transmission-connected with the linear motion module 1231, and the linear motion module 1231 can provide power for the movement of the support frame 1232, thereby driving the support frame 1232 to perform linear motion in the up and down directions. Further, the second moving mechanism 123 and the drive motor 1222 are sequentially distributed along the second direction, that is, the second moving mechanism 123 in the present application is located below the drive motor 1222, so as to avoid interference between the support frame 1232 and the drive motor 1222 during the up and down movement, thereby affecting the normal operation of the drive motor 1222.

[0028] Furthermore, the connecting bracket 121 also includes a drag chain 1214 and a drag chain bracket 1213, the drag chain 1214 is arranged on the drag chain bracket 1213, the drag chain bracket 1213 and the guide rail slider structure 1211 are sequentially distributed along the second direction, and in the present application, the drag chain bracket 1213 is located above the guide rail slider structure 1211. Through the above arrangement, the drag chain 1214 is mainly used to bind cables, wires or air pipes, so that the cables, wires or air pipes can move with the first moving mechanism 122 or the second moving mechanism 123, and the drag chain bracket 1213 is located above the guide rail slider structure 1211, which can also avoid interference between the drag chain 1214 and the guide rail slider structure 1211.

[0029] like Figure 4 As shown, as an implementation, the insulation withstand voltage test device 100 further includes a second moving component 14, and the structure of the second moving component 14 is substantially consistent with the structure of the first moving component 12, that is, the second moving component 14 also includes a connecting bracket 121, a first moving mechanism 122 and a second moving mechanism 123. Specifically, the number of the first moving component 12 is set to at least one (refer to Figure 1 ). When the first movable assembly 12 is set to one, the first movable assembly 12 and the second movable assembly 14 are sequentially distributed along the third direction, wherein the third direction is perpendicular to the first direction and the second direction; when the first movable assembly 12 is set to be greater than one, multiple first movable assemblies 12 are distributed on both sides of the second movable assembly 14 along the third direction. It can be understood that the third direction of the present application refers to the left and right direction of the insulation withstand voltage test equipment 100. Through the above-mentioned setting, the first movable assembly 12 and the second movable assembly 14 cooperate with multiple test fixtures 13 to move together to perform insulation withstand voltage test, which can effectively improve the test efficiency of photovoltaic components, thereby avoiding the photovoltaic components from consuming too much time in the test link during the production process, thereby improving the production capacity of the entire production line. In addition, multiple test fixtures 13 are integrated and arranged on the same equipment bracket through the first movable assembly 12 and the second movable assembly 14, which can also greatly reduce the floor space of the insulation withstand voltage test equipment 100, improve the space utilization rate of the insulation withstand voltage test equipment 100, and enable more test fixtures 13 to work without changing the detection site, thereby improving the work efficiency of the entire production line.

[0030] As a preferred embodiment, the number of the first moving components 12 of the present application is set to two, and the two first moving components 12 are respectively located on the left and right sides of the second moving component 14. Since the second moving component 14 located in the middle has less space for arrangement, if the second moving component 14 is arranged in the same manner as the first moving component 12, the second moving component 14 is likely to interfere with the first moving component 12 during operation. Figure 4As shown, in the present application, the guide rail slider structure of the first moving component 12 and the connecting bracket of the first moving component 12 are sequentially distributed along the third direction, and the guide rail slider structure of the second moving component 14 and the connecting bracket of the second moving component 14 are sequentially distributed along the second direction, that is, the guide rail slider structure of the first moving component 12 is arranged on the left or right side of the connecting bracket of the first moving component 12, and the guide rail slider structure of the second moving component 14 is arranged on the upper side of the connecting bracket of the second moving component 14. The second moving component 14 includes a second mounting frame 141, the second mounting frame 141 is slidably connected to the guide rail slider structure of the second moving component 14, the support frame of the second moving component 14 is connected to the second mounting frame 141, the second mounting frame 141 extends to the left and right sides along the third direction to form an extension portion 1411, the extension portion 1411 is slidably connected to the guide rail slider structure of the second moving component 14, and when viewed along the third direction, the extension portion 1411 at least partially overlaps with the guide rail slider structure of the second moving component 14. Through the above-mentioned setting, the guide rail slider structure of the second movable component 14 is arranged above the connecting bracket of the second movable component 14, and the sliding connection between the second mounting frame and the guide rail slider structure of the second movable component 14 is realized through the extension part 1411, which can reduce the layout space occupied by the second movable component 14 and improve the space utilization rate of the insulation withstand voltage testing equipment 100.

[0031] like Figure 3 and Figure 5 As shown, since the first movable component 12 and the second movable component 14 are arranged along the second direction in the present application, when the arrangement distance between the first movable component 12 and the second movable component 14 is too close, the test fixture 13 of the first movable component 12 and the second movable component 14 are prone to interfere with each other during the movement. In order to avoid the test fixture 13 from interfering with the second movable component 14 during the movement, the test fixtures 13 of the first movable component 12 and the second movable component 14 are both provided with an avoidance state. When observed along the front and rear directions of the insulation and voltage withstand test equipment 100, the first movable component 12, the second movable component 14 and the test fixture 13 do not overlap with each other. Therefore, when the test fixture 13 is in the avoidance state, the test fixture 13 of the first movable component 12 and the test fixture of the second movable component 14 will not interfere with each other during the movement, thereby ensuring the working smoothness and stability of the insulation and voltage withstand test equipment 100 on the entire production line of photovoltaic components.

[0032] Specifically, the second moving mechanism 123 of the first moving assembly 12 in the present application further includes a rotating frame 1233, the rotating frame 1233 is located below the support frame 1232 and is rotatably connected to the support frame 1232, and the test fixture 13 on the first moving assembly 12 is fixedly connected to the rotating frame 1233. Further, a rotating motor 1232a is provided on the support frame 1232, and a rotating shaft 1233a is provided on the rotating frame 1233. The axis of the rotating motor 1232a and the axis of the rotating shaft 1233a are located in the same straight line, and the axis direction of the rotating shaft 1233a is consistent with the first direction. When the test fixture 13 completes the detection work, the first movable component 12 returns to the initial position. To avoid interference with the second movable component 14, the rotating motor 1232a drives the rotating shaft 1233a to rotate, so that the side of the rotating frame 1233 away from the rotation center moves toward the direction close to the support frame 1232, thereby folding the test fixture 13 through the rotation of the rotating frame 1233, and moving upward through the second movable mechanism 123 to adjust to the avoidance state. When the test fixture 13 of the first movable component 12 is in the avoidance state, the test fixture 13 of the first movable component 12 is located above the test fixture 13 of the second movable component 12, so that the test fixture 13 of the second movable component 14 and the test fixture of the first movable component 12 are misaligned with each other, thereby avoiding interference between the first movable component 12 and the test fixture 13 on the second movable component 14 in the process of returning to the initial position through the first movable mechanism 122. Through the above settings, the avoidance state can also make the distance between the first movable assembly 12 and the second movable assembly 14 smaller, thereby improving the space utilization of the insulation and voltage withstand testing equipment 100.

[0033] It can be understood that the transformation method of the test fixture 13 of the first moving assembly 12 of the present application into the avoidance state through the rotating frame 1233 is only a preferred embodiment, and other settings that make the test fixture 13 of the first moving assembly 12 transform into the avoidance state also fall within the scope of protection of the present application. For example, the first moving assembly 12 can also make the test fixture 13 in the avoidance state by moving the test fixture 13 in the left-right direction and then cooperating with the second moving mechanism 123 to move in the up-down direction.

[0034] like Figure 5As shown, in this embodiment, since the second moving assembly 14 of the present application is located between the two first moving assemblies 12, if the second moving assembly 14 is also provided with a rotating frame 1233, the test fixture 13 on the second moving assembly 14 is in an avoidance state and is prone to interfere with the test fixture 13 on the adjacent first moving assembly 12. In order to ensure that both the first moving assembly 12 and the second moving assembly 14 can work normally, the second moving assembly 14 in the present application is not provided with a rotating frame 1233, and the test fixture 13 on the second moving assembly 14 is directly fixed to the support frame of the second moving assembly 14. The first moving assembly 100 is connected to the second moving assembly 14, that is, the test fixture 13 of the second moving assembly 14 can only realize up-down movement and forward-backward movement. When the test fixture 13 on the second moving assembly 14 completes the insulation withstand voltage test on the photovoltaic assembly, the second moving assembly 14 first moves upward through the second moving mechanism 123 to change to the avoidance state. When the second moving assembly 14 is in the avoidance state, the test fixture 13 of the second moving assembly 14 is located above the test fixture 13 of the first moving assembly 12, and then returns to the initial position before the insulation withstand voltage test through the first moving mechanism 122, thereby avoiding interference with the first moving assembly 12. Through the above arrangement, during the photovoltaic assembly test process, the first moving assembly 12, the second moving assembly 14, and the first moving assembly 12 at the rear can successively detect the photovoltaic assembly and successively change to the avoidance state and return to the initial position before the insulation withstand voltage test. During the whole process, the first moving assembly 12, the second moving assembly 14, and the test fixture 13 will not interfere with each other, thereby improving the working efficiency of the insulation withstand voltage test equipment 100.

[0035] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this application.
