[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The following is for reference. Figures 1-2 A testing apparatus 100 for a thermoelectric device 200 according to an embodiment of the present invention is described.

[0036] like Figure 1 and Figure 2 As shown, the inspection device 100 for thermoelectric device 200 according to an embodiment of the present invention includes: a mounting base 1; a position adjustment mechanism 2, which is disposed on the mounting base 1, and the upper surface of the position adjustment mechanism 2 is used to place the thermoelectric device 200, and the position adjustment mechanism 2 is used to adjust the position of the thermoelectric device 200 in a first direction and / or a second direction, wherein the first direction, the second direction and the height direction of the inspection device 100 are perpendicular to each other; a first mounting bracket 3, which is disposed on the mounting base 1 and movable along the height direction of the inspection device 100; a flatness detection element 4, which is fixed on the first mounting bracket 3 and located above the position adjustment mechanism 2, and the flatness detection element 4 is used to detect the height of different thermoelectric arms 201 of the thermoelectric device 200; and a controller 5, which is communicatively connected to the flatness detection element 4, and the controller 5 is configured to determine the flatness of the thermoelectric device 200 based on the detection information of the flatness detection element 4.

[0037] The mounting base 1 provides support for the inspection device 100, thereby improving its operational stability. The mounting base 1 may have multiple evenly arranged mounting holes 14. By providing multiple mounting holes 14, the position adjustment mechanism 2 can be adjusted to change its assembly position as needed, thus improving the versatility of the inspection device 100. As some embodiments of this application, along the height direction of the inspection device 100, i.e. Figure 1 In the Z direction, the bottom of the mounting base 1 may be provided with a support foot 15. The support foot 15 may be, but is not limited to, made of rubber material, to further improve the stability of the inspection device 100.

[0038] In some embodiments of this application, the position adjustment mechanism 2 and the mounting base 1 can be connected by bolts so that the position adjustment mechanism 2 is disposed on the mounting base 1. In some embodiments of this application, the position adjustment mechanism 2 and the mounting base 1 can be snap-fit ​​connected so that the position adjustment mechanism 2 is disposed on the mounting base 1. The position adjustment mechanism 2 is used to place the thermoelectric device 200. By placing the thermoelectric device 200 on the upper surface of the position adjustment mechanism 2, the position adjustment mechanism 2 can adjust the position of the thermoelectric device 200.

[0039] As some embodiments of this application, the position adjustment mechanism 2 can adjust the position of the thermoelectric device 200 in a first direction. As some embodiments of this application, the position adjustment mechanism 2 can adjust the position of the thermoelectric device 200 in a second direction. As some embodiments of this application, the position adjustment mechanism 2 can adjust the position of the thermoelectric device 200 in both the first and second directions. The first direction is... Figure 1 The X direction, the second direction is... Figure 1 In this context, the Y-direction, the first direction, the second direction, and the height direction of the inspection device 100 are perpendicular to each other; that is, the X-direction, Y-direction, and Z-direction are perpendicular to each other. This application uses the example of the position adjustment mechanism 2 being able to adjust the position of the thermoelectric device 200 in both the first and second directions. By adjusting the position of the thermoelectric device 200 through the position adjustment mechanism 2, the thermoelectric device 200 can be placed in a suitable detection position, thereby enabling the inspection device 100 to successfully detect the thermoelectric device 200.

[0040] In some embodiments of this application, the first mounting bracket 3 can be mounted on the mounting base 1 via a slide rail device, allowing the first mounting bracket 3 to be movable relative to the mounting base 1 along the height direction of the inspection device 100. In some embodiments of this application, the flatness testing element 4 can be bolted to the first mounting bracket 3, fixing the flatness testing element 4 to the first mounting bracket 3. In some embodiments of this application, the flatness testing element 4 can be snap-fitted to the first mounting bracket 3, fixing the flatness testing element 4 to the first mounting bracket 3. By fixing the flatness testing element 4 to the first mounting bracket 3, the flatness testing element 4 can move together with the first mounting bracket 3, thereby facilitating adjustment of the position of the flatness testing element 4 in the height direction of the inspection device 100.

[0041] Along the height direction of the inspection device 100, the flatness testing element 4 is located above the position adjustment mechanism 2. The flatness testing element 4 has a midpoint in its range along the height direction. By adjusting the first mounting bracket 3, the height of the flatness testing element 4 can be adjusted so that the flatness testing element 4 is moved to the position where the upper end surface of the thermoelectric device 200 is at or approximately at the midpoint of its range, thereby facilitating the flatness testing element 4 to inspect the upper end surface of the thermoelectric device 200.

[0042] The thermoelectric device 200 may include multiple thermoelectric arms 201, and the flatness detection element 4 can detect the height of different thermoelectric arms 201. The controller 5 and the flatness detection element 4 are communicatively connected. In some embodiments of this application, the controller 5 and the flatness detection element 4 can be connected via a data cable 300. In some embodiments of this application, the controller 5 and the flatness detection element 4 can be connected via Bluetooth. This configuration allows the flatness detection element 4 to transmit detection information to the controller 5, and the controller 5 to determine the flatness of the thermoelectric device 200 based on the detection information from the flatness detection element 4.

[0043] As some embodiments of this application, the flatness measuring element 4 can measure the height of the hot end face of the thermoelectric device 200 using a white light confocal method. As some embodiments of this application, the flatness measuring element 4 can measure the height of the hot end face of the thermoelectric device 200 using a relative depth gauge method, thereby inferring the flatness of the thermoelectric device 200. This eliminates the need for the flatness measuring element 4 to contact the thermoelectric device 200, and the position adjustment mechanism 2 drives the thermoelectric device 200 to move together according to a set setting, eliminating the need for relative movement between the thermoelectric device 200 and the position adjustment mechanism 2. This improves the automation and accuracy of the thermoelectric device 200 during the measurement process.

[0044] When the controller 5 receives a signal indicating that the heights of the different thermoelectric arms 201 are the same or approximately the same, the controller 5 can determine that the flatness of the thermoelectric device 200 is good and the quality of the thermoelectric device 200 is qualified. When the controller 5 receives a signal indicating that the heights of the different thermoelectric arms 201 are different, the controller 5 can determine that the flatness of the thermoelectric device 200 is poor and the quality of the thermoelectric device 200 is poor, thus facilitating the selection of qualified thermoelectric devices 200.

[0045] Specifically, the thermoelectric device 200 to be tested is placed on the upper surface of the position adjustment mechanism 2. The first mounting bracket 3 is adjusted so that the flatness detection element 4 can move with the first mounting bracket 3, thereby positioning the flatness detection element 4 in a suitable position, i.e., the upper end face of the thermoelectric device 200 is at or approximately at the midpoint of the flatness detection element 4's measurement range. The controller 5 may have a pre-programmed sequence. By controlling the position adjustment mechanism 2 according to the set sequence, the controller 5 adjusts the position of the thermoelectric device 200 in the first and second directions, so that the multiple thermoelectric arms 201 of the thermoelectric device 200 sequentially coincide with the projection of the flatness detection element 4 in the height direction. This facilitates the flatness detection element 4 to sequentially detect the multiple thermoelectric arms 201 of the thermoelectric device 200. The controller 5 can read the height information of different thermoelectric arms 201 detected by the flatness detection element 4 and determine the flatness of the thermoelectric device 200 based on the detection information of the flatness detection element 4, thereby selecting qualified thermoelectric devices 200.

[0046] Therefore, by setting up a flatness detection component 4 and a controller 5, the controller 5 can determine the flatness of the thermoelectric device 200 based on the detection information of the flatness detection component 4, thereby accurately judging the quality of the thermoelectric device 200, so as to screen out qualified thermoelectric devices 200.

[0047] In some embodiments of the present invention, such as Figure 2 As shown, the controller 5 and the position adjustment mechanism 2 are communicatively connected, and the controller 5 is configured to control the position adjustment mechanism 2 to adjust the position of the thermoelectric device 200.

[0048] In some embodiments of this application, the controller 5 and the position adjustment mechanism 2 can be connected via a data cable 300. In other embodiments, the controller 5 and the position adjustment mechanism 2 can be connected via Bluetooth. This communication connection allows the controller 5 to control the movement of the position adjustment mechanism 2, thereby adjusting the position of the thermoelectric device 200. This reduces the difficulty of adjusting the position of the thermoelectric device 200 and improves the efficiency of quality inspection of the thermoelectric device 200.

[0049] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the position adjustment mechanism 2 may include: a first position adjustment component 21 and a second position adjustment component 22. The second position adjustment component 22 is disposed on the first position adjustment component 21 and located above the first position adjustment component 21. The second position adjustment component 22 is used to place the thermoelectric device 200. The first position adjustment component 21 is adapted to drive the second position adjustment component 22 to move the thermoelectric device 200 along a first direction. The second position adjustment component 22 is adapted to drive the thermoelectric device 200 to move along a second direction.

[0050] In some embodiments of this application, both the first position adjustment component 21 and the second position adjustment component 22 can be driven by a motor. In other embodiments, both the first position adjustment component 21 and the second position adjustment component 22 can be driven by a cylinder. The second position adjustment component 22 is disposed on the first position adjustment component 21, for example, but not limited to, by means of bolts, snap-fits, etc. Along the height direction of the inspection device 100, the second position adjustment component 22 is located above the first position adjustment component 21. The thermoelectric device 200 can be placed on the second position adjustment component 22. The first position adjustment component 21 can adjust the position of the thermoelectric device 200 along a first direction, and the second position adjustment component 22 can adjust the position of the thermoelectric device 200 along a second direction.

[0051] Specifically, when the position of the thermoelectric device 200 needs to be adjusted, the first position adjustment component 21 can drive the second position adjustment component 22 to move along the first direction. The second position adjustment component 22 drives the thermoelectric device 200 to move along the first direction so that the position of the thermoelectric device 200 in the first direction is reasonable. When the position adjustment of the thermoelectric device 200 in the first direction is completed, the second position adjustment component 22 drives the thermoelectric device 200 to move along the second direction so that the position of the thermoelectric device 200 in the second direction is reasonable. Thus, the position adjustment of the thermoelectric device 200 in both the first and second directions is completed. At this time, the projection of the thermoelectric device 200 in the height direction coincides with that of the flatness detection component 4, which facilitates the flatness detection component 4 to smoothly detect the thermoelectric device 200.

[0052] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the first position adjustment component 21 may include: a first driving member 211, a first fixed block 212 and a first moving block 213. The first fixed block 212 is fixed to the mounting base 1. The first moving block 213 is slidably disposed on the first fixed block 212 along a first direction and located above the first fixed block 212. The first driving member 211 is connected to the first moving block 213 to drive the first moving block 213 to slide. The first driving member 211 is communicatively connected to the controller 5.

[0053] In some embodiments of this application, the first driving member 211 can be configured as a drive motor. In some embodiments of this application, the first driving member 211 can be configured as a drive cylinder. In some embodiments of this application, the first fixing block 212 and the mounting base 1 can be connected by bolts to fix the first fixing block 212 to the mounting base 1. In some embodiments of this application, the first fixing block 212 and the mounting base 1 can be snap-fitted together to fix the first fixing block 212 to the mounting base 1. Furthermore, by passing bolts through different mounting holes 14, or by snapping the first fixing block 212 into different mounting holes 14, the first fixing block 212 can be fixed at different positions on the mounting base 1 to accommodate different types of thermoelectric devices 200.

[0054] As some embodiments of this application, the first fixed block 212 may have a slide rail, and the first moving block 213 may have a pulley. Along the first direction, the first moving block 213 is slidably disposed on the first fixed block 212, and along the height direction of the inspection device 100, the first moving block 213 is located above the first fixed block 212. The first driving member 211 is connected to the first moving block 213 so that the first driving member 211 can drive the first moving block 213 to slide along the first direction, thereby causing the first moving block 213 to drive the second position adjustment component 22 to move along the first direction, thereby causing the thermoelectric device 200 on the second position adjustment component 22 to move to a suitable position in the first direction.

[0055] The first driving element 211 and the controller 5 are communicatively connected. In some embodiments of this application, the controller 5 and the first driving element 211 can be connected via a data cable 300. In some embodiments of this application, the controller 5 and the first driving element 211 can be connected via Bluetooth. Through the communicative connection between the controller 5 and the first driving element 211, the controller 5 can control the first driving element 211 to drive the first moving block 213 to move along a first direction, reducing the difficulty of adjusting the position of the first moving block 213, thereby improving the quality inspection efficiency of the thermoelectric device 200.

[0056] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the second position adjustment component 22 may include: a second driving member 221, a second fixed block 222, and a second moving block 223. The second fixed block 222 is fixed to the first moving block 213. The second moving block 223 is slidably disposed on the second fixed block 222 along the second direction and is located above the second fixed block 222. The second driving member 221 is connected to the second moving block 223 to drive the second moving block 223 to slide. The second driving member 221 is communicatively connected to the controller 5.

[0057] In some embodiments of this application, the second driving member 221 can be configured as a drive motor. In some embodiments of this application, the second driving member 221 can be configured as a drive cylinder. In some embodiments of this application, the second fixing block 222 and the first moving block 213 can be connected by bolts, so that the second fixing block 222 is fixed to the first moving block 213. In some embodiments of this application, the second fixing block 222 and the first moving block 213 can be snap-fit ​​connected, so that the second fixing block 222 is fixed to the first moving block 213.

[0058] As some embodiments of this application, the second fixed block 222 may have a slide rail, and the second moving block 223 may have a pulley. The second moving block 223 is slidably disposed on the second fixed block 222 along the second direction, and the second moving block 223 is located above the second fixed block 222 along the height direction of the inspection device 100. The second driving member 221 is connected to the second moving block 223 so that the second driving member 221 can drive the second moving block 223 to slide along the second direction, thereby causing the second moving block 223 to drive the thermoelectric device 200 to move along the second direction, and thus causing the thermoelectric device 200 to move to a suitable position in the second direction.

[0059] The second drive unit 221 and the controller 5 are communicatively connected. In some embodiments of this application, the controller 5 and the second drive unit 221 can be connected via a data cable 300. In some embodiments of this application, the controller 5 and the second drive unit 221 can be connected via Bluetooth. Through the communicative connection between the controller 5 and the second drive unit 221, the controller 5 can control the second drive unit 221 to drive the second moving block 223 to move along a second direction, reducing the difficulty of adjusting the position of the second moving block 223, thereby improving the quality inspection efficiency of the thermoelectric device 200.

[0060] In some embodiments of the present invention, such as Figure 2 As shown, the mounting base 1 has a second mounting bracket 11, which is located on one side of the position adjustment mechanism 2. The second mounting bracket 11 is provided with a third position adjustment component 12, which is connected to the first mounting bracket 3. The third position adjustment component 12 is used to drive the first mounting bracket 3 to move along the height direction of the inspection device 100.

[0061] The mounting base 1 has a second mounting bracket 11, which includes a first plate 111, a second plate 112, and a reinforcing plate 113. The first plate 111 and the second plate 112 are fixedly connected and are arranged vertically or approximately vertically. The reinforcing plate 113 is connected between the first plate 111 and the second plate 112 to increase the connection strength between the first plate 111 and the second plate 112, thereby improving the structural strength of the second mounting bracket 11.

[0062] The second mounting bracket 11 is located on one side of the position adjustment mechanism 2, and the third position adjustment component 12 may be mounted on the second mounting bracket 11 by means of bolts, snap-fits, etc. As some embodiments of this application, the third position adjustment component 12 may be located on the side of the second mounting bracket 11 facing the position adjustment mechanism 2. As some embodiments of this application, the second mounting bracket 11 has opposing side walls along a second direction, and the third position adjustment component 12 may be located on either side wall.

[0063] The third position adjustment component 12 is connected to the first mounting bracket 3. For example, the third position adjustment component 12 and the first mounting bracket 3 can be directly connected, or they can be indirectly connected through a connector. By connecting the third position adjustment component 12 to the first mounting bracket 3, the third position adjustment component 12 can drive the first mounting bracket 3 to move along the height direction of the inspection device 100, thereby adjusting the flatness detection element 4 on the first mounting bracket 3 along the height direction of the inspection device 100. This allows the flatness detection element 4 to move until the upper end face of the thermoelectric device 200 is at or approximately at the midpoint of its measurement range, thus facilitating the flatness detection element 4 to inspect the upper end face of the thermoelectric device 200.

[0064] In some embodiments of the present invention, such as Figure 1 As shown, the third position adjustment assembly 12 is connected between the second mounting bracket 11 and the first mounting bracket 3, so that the first mounting bracket 3 is mounted on the mounting base 1 via the third position adjustment assembly 12.

[0065] The third position adjustment component 12 can be disposed on the side of the second mounting bracket 11 facing the position adjustment mechanism 2, and the first mounting bracket 3 can be disposed on the side of the third position adjustment component 12 away from the position adjustment mechanism 2, so that the third position adjustment component 12 is connected between the second mounting bracket 11 and the first mounting bracket 3. That is, the second mounting bracket 11, the third position adjustment component 12 and the first mounting bracket 3 are arranged sequentially along the first direction, so that the first mounting bracket 3 is installed on the mounting base 1 through the third position adjustment component 12 and connected between the second mounting bracket 11 and the first mounting bracket 3 through the third position adjustment component 12. This allows the third position adjustment component 12 and the first mounting bracket 3 to be directly connected, reducing the assembly difficulty of the second mounting bracket 11, the third position adjustment component 12 and the first mounting bracket 3, and improving the assembly efficiency of the inspection device 100.

[0066] In some embodiments of the present invention, such as Figure 1 As shown, the third position adjustment component 12 may include: a third driving member 121, a third fixed block 122 and a third moving block 123. The third fixed block 122 is fixed to the second mounting bracket 11. The third moving block 123 is slidably disposed on the third fixed block 122 along the height direction of the inspection device 100. The third driving member 121 is connected to the third moving block 123 to drive the third moving block 123 to slide. The first mounting bracket 3 is fixed to the third moving block 123.

[0067] In some embodiments of this application, the third driving member 121 can be configured as a drive motor. In some embodiments of this application, the third driving member 121 can be configured as a drive cylinder. In some embodiments of this application, the third fixing block 122 and the second mounting bracket 11 can be connected by bolts, so that the third fixing block 122 is fixed to the second mounting bracket 11. In some embodiments of this application, the third fixing block 122 and the second mounting bracket 11 can be snap-fit ​​connected, so that the third fixing block 122 is fixed to the second mounting bracket 11.

[0068] As some embodiments of this application, the third fixed block 122 may have a worm gear, and the third moving block 123 may have a worm. The third moving block 123 is movably disposed on the third fixed block 122 along a third direction. As some embodiments of this application, the third fixed block 122 may have a slide rail, and the third moving block 123 may have a pulley. The third moving block 123 is slidably disposed on the third fixed block 122 along a third direction. Furthermore, the third driving member 121 is connected to the third moving block 123 so that the third driving member 121 can drive the third moving block 123 to slide along the height direction of the inspection device 100. The first mounting bracket 3 is fixed to the third moving block 123 so that the third moving block 123 drives the first mounting bracket 3 to move along the height direction of the inspection device 100, thereby causing the flatness detection member 4 to move with the first mounting bracket 3 to a suitable position in the height direction of the inspection device 100, that is, the flatness detection member 4 moves until the upper end surface of the thermoelectric device 200 is at or approximately at the midpoint of the flatness detection member 4's measurement range.

[0069] In some embodiments of the present invention, such as Figure 1 As shown, the third position adjustment component 12 is configured as a manual adjustment component 13.

[0070] The third position adjustment component 12 can be configured as a manual adjustment component 13. The third position adjustment component 12 may include an operation part 131, which is the third drive member 121 in the above embodiment. By rotating the operation part 131, the third moving block 123 can slide along the height direction of the inspection device 100, thereby controlling the movement of the first mounting bracket 3 and the flatness detection member 4. Furthermore, the travel distance of the third moving block 123 can be determined based on the distance between the flatness detection member 4 and the thermoelectric device 200.

[0071] Compared to constructing the third position adjustment component 12 as an electrically adjustable component, constructing the third position adjustment component 12 as a manually adjustable component 13 can improve the adjustment reliability of the third position adjustment component 12, reduce the risk of interference between the flatness detection component 4 and the thermoelectric device 200 caused by excessive downward movement of the third moving block 123 along the height direction of the inspection device 100, thereby reducing the risk of damage to the flatness detection component 4 or the thermoelectric device 200 and improving the operational safety of the inspection device 100.

[0072] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the inspection device 100 may further include: a telescopic rod mechanism 6, which is fixed to the first mounting frame 3 and located above the position adjustment mechanism 2. The first mounting frame 3 is adapted to drive the telescopic rod mechanism 6 to move along the height direction of the inspection device 100. The telescopic rod mechanism 6 has a telescopic rod 61, and the lower end of the telescopic rod 61 has a probe 62. The controller 5 is communicatively connected to the telescopic rod mechanism 6.

[0073] The telescopic rod mechanism 6 may include a pressure sensor (not shown in the figure). In some embodiments of this application, the telescopic rod mechanism 6 and the first mounting frame 3 can be bolted together to fix the telescopic rod mechanism 6 to the first mounting frame 3. In some embodiments of this application, the telescopic rod mechanism 6 and the first mounting frame 3 can be snap-fitted together to fix the telescopic rod mechanism 6 to the first mounting frame 3. Along the height direction of the inspection device 100, the telescopic rod mechanism 6 is located above the position adjustment mechanism 2, and the first mounting frame 3 can drive the telescopic rod mechanism 6 to move along the height direction of the inspection device 100, so that the position of the telescopic rod mechanism 6 is reasonably set, facilitating the inspection of the thermoelectric device 200 by the telescopic rod mechanism 6 above the position adjustment mechanism 2. The telescopic rod mechanism 6 has a telescopic rod 61, the lower end of which has a probe 62. The controller 5 is communicatively connected to the telescopic rod mechanism 6, so that the controller 5 can control the telescopic rod 61 to extend and retract along the height direction of the inspection device 100.

[0074] Specifically, the controller 5 may have a pre-edited program. The first position adjustment component 21 and the second position adjustment component 22 control the movement of the thermoelectric device 200 according to the program settings, so that different thermoelectric arms 201 on the thermoelectric device 200 move sequentially to below the probe 62. The controller 5 controls the telescopic rod 61 to extend and retract along the height direction of the inspection device 100, so that the probe 62 abuts against different thermoelectric arms 201 sequentially. It should be noted that the telescopic rod 61 extends and retracts the same distance multiple times along the height direction of the inspection device 100.

[0075] As some embodiments of this application, when the pressure detected by the pressure sensor is less than the standard pressure, it indicates that there is displacement after the thermoelectric arm 201 comes into contact with the probe 62, meaning that there is a defect such as a poor weld in the welding of the thermoelectric arm 201. By detecting the pressure response of different thermoelectric arms 201 by the pressure sensor, the controller 5 plots the displacement-pressure response curve of the thermoelectric arm 201 based on the pressure detected by the pressure sensor, and compares it with the displacement-pressure curve of a normal thermoelectric arm 201 to determine whether there is a problem with the material or welding of the thermoelectric arm 201, thereby screening out qualified thermoelectric devices 200.
