[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0043] like Figures 1 to 6 As shown, this embodiment provides a charging interface 100 insertion and extraction force testing device, including a test bracket (not shown in the figure), a tray 1, an insertion / extraction head 2, an insertion / extraction mechanism 3, and a monitoring mechanism 4.

[0044] The test support includes a tray 1, configured to hold the charging interface 100 to be tested, and a test port 11. A plug-in head 2 is located on the side of the test support away from the tray 1. The plug-in head 2 is connected to the output of a plug-in mechanism 3, which drives the plug-in head 2 to pass through the test port 11 and insert into or remove from the charging interface 100. A monitoring mechanism 4 is located on the plug-in mechanism 3 and collects the insertion / removal force required for the plug-in head 2 to insert into the charging interface 100.

[0045] like Figures 1 to 3 As shown, in this embodiment, the tray 1 is set above the test bracket, the plugging and unplugging mechanism 3 is set below the tray 1, the charging port 100 to be tested is placed on the tray 1 with the charging port facing down, and the plugging and unplugging head 2 can pass through the test port 11 on the tray 1 and be inserted into the charging port 100 to be tested.

[0046] It is understood that the charging interface 100 insertion and extraction force testing device provided in this embodiment drives the insertion and extraction head 2 to be inserted into the charging interface 100 to be tested or to be pulled out of the charging interface 100 to be tested through the insertion and extraction mechanism 3. Compared with manual operation, it can reduce errors. Moreover, through the monitoring mechanism 4 connected to the insertion and extraction mechanism 3, the insertion and extraction force and insertion and extraction depth of the insertion and extraction head 2 can be captured in real time when the insertion and extraction head 2 is inserted into the charging interface 100 to be tested, which further improves the accuracy of the test results.

[0047] In some embodiments, in order to facilitate the transport of the charging interface 100 to be tested from the upstream process to the testing device, the charging interface 100 insertion and extraction force testing device further includes a drive mechanism (not shown in the figure), a slide rail 5 is provided on the test bracket, the tray 1 is slidably disposed on the slide rail 5, and can move along the slide rail 5 to a preset test position, the drive mechanism is used to drive the tray 1 to move along the slide rail 5, when the tray 1 is located at the test position, the test port 11 is directly opposite the insertion head 2.

[0048] Specifically, such as Figure 1 and Figure 4As shown, in this embodiment, the slide rail 5 is positioned above the test bracket, and a slider 12 cooperating with the slide rail 5 is positioned below the tray 1. The tray 1 can slide along the extension direction of the slide rail 5 under the action of the slide rail 5 and the slider 12, thereby achieving rapid transport of the charging interface 100 to be tested. It can be understood that the charging interface 100 to be tested is matched with the test port 11 of the tray 1 in the upstream process, such as by fixing the charging interface 100 to the tray 1 with bolts or by using snap-fit ​​mechanisms to limit the position of the charging interface 100 placed on the tray 1. This allows the charging interface 100 to be tested to be directly tested via the insertion / removal mechanism 3 when the tray 1 moves to the test station, effectively improving testing efficiency. The driving mechanism includes, but is not limited to, a drive motor.

[0049] In some embodiments, to further secure and maintain the position of the charging interface 100 under test relative to the tray 1 during testing, preventing displacement, shaking, or lifting under the action of insertion and extraction forces, the charging interface 100 insertion and extraction force testing device also includes a clamping mechanism 6. The clamping mechanism 6 is disposed on the side of the tray 1 away from the test support, and the clamping mechanism 6 can press the charging interface 100 under test firmly onto the tray 1. It is understood that by setting the clamping mechanism 6, the charging interface 100 under test can be fixed on the tray 1, preventing the charging interface 100 under test from being lifted off the tray 1 when the insertion and extraction mechanism 3 moves upward with the insertion and extraction head 2.

[0050] In some embodiments, the clamping mechanism 6 includes a clamping member 61 and a clamping drive member 62. The clamping drive member 62 is disposed on one side of the slide rail 5. The clamping drive member 62 can drive the clamping member 61 to abut against the charging interface 100 to be tested in a direction perpendicular to the tray 1 or drive the clamping member 61 away from the charging interface 100 to be tested.

[0051] Specifically, such as Figure 1 and Figure 6 As shown, the clamping drive 62 is mounted on the test bracket and located on the side of the slide rail 5. The clamping member 61 is an L-shaped plate that can cooperate with the upper surface of the charging interface 100, so that when the clamping member 61 clamps the charging interface 100 to be tested, the charging interface 100 to be tested is subjected to uniform force, thereby improving the fixing effect of the clamping mechanism 6 on the charging interface 100 to be tested. The clamping member 61 is placed horizontally above the test station. When the tray 1 moves to the test station, the clamping member 61 moves downward under the drive of the clamping drive until it abuts against the charging interface 100 to be tested placed on the tray 1, so that the position of the charging interface 100 to be tested relative to the tray 1 is stable during the test, thereby ensuring the accuracy of the test results.

[0052] Furthermore, to prevent the clamping member 61 positioned above the testing station from interfering with the sliding of the tray 1 when it slides on the slide rail 5, in some embodiments, the clamping mechanism 6 further includes a rotary drive member 63, which can drive the clamping member 61 to rotate. By providing the rotary drive member 63, when the tray 1 slides on the slide rail 5, the rotary drive member 63 drives the clamping member 61 to rotate, causing the clamping member 61 to move away from the sliding path of the tray 1, thus preventing the clamping member 61 from interfering with the sliding of the tray 1. It is understood that the rotary drive member 63 can drive the clamping member 61 to rotate in a vertical plane or in a plane parallel to the tray 1, as long as the clamping member 61 does not interfere with the sliding of the tray 1.

[0053] Specifically, such as Figure 6 As shown, in this embodiment, the rotary drive 63 is disposed at the output end of the clamping drive 62, and the clamping member 61 is connected to the output end of the rotary drive 63. The charging interface 100 insertion and extraction force testing device provided in this embodiment can drive the rotary drive 63 to move the clamping member 61 up and down through the clamping drive 62, so that while testing the charging interface 100 to be tested, the clamping member 61 can also be rotated in a plane parallel to the tray 1 through the rotary drive 63 when not testing, avoiding interference from the sliding of the tray 1 by the clamping member 61, which is beneficial to improving testing efficiency.

[0054] Of course, in some other embodiments, the clamping drive 62 can be set at the output end of the rotary drive 63, and the rotary drive 63 can drive the clamping drive 62 and the clamping member 61 to rotate at the same time. This embodiment will not be described in detail.

[0055] Specifically, such as Figure 4 As shown, in this embodiment, the monitoring mechanism 4 includes a force sensor 41 and a distance sensor 42. The insertion / removal mechanism 3 is a servo insertion / removal machine. Both the force sensor 41 and the distance sensor 42 are connected to the servo insertion / removal machine. It can be understood that the servo insertion / removal machine, as the driving core, can provide precise, smooth, and programmable linear motion, completely eliminating the instability and randomness of manual operation. This provides a stable and linear displacement reference for the distance sensor 42. A spring is installed inside the distance sensor 42. When the insertion / removal mechanism 3 drives the insertion / removal head 2 upward, the distance sensor 42 contacts the tray 1 and is compressed. When the insertion / removal mechanism 3 pulls out the insertion / removal head 2, it resets and recovers. The distance sensor 42 can provide real-time feedback on the precise position of the insertion / removal head 2. The force sensor 41 directly monitors the resistance change of the servo insertion / removal machine carrying the insertion / removal head 2 during the insertion / removal process. This allows for strict time-series synchronous acquisition of the insertion / removal force and insertion / removal depth.

[0056] To facilitate the observation of test data by testers, in some embodiments, a display 7 is provided on the test bracket, and the display 7 is connected to the monitoring mechanism 4.

[0057] More specifically, in this embodiment, the display 7 is equipped with a processor. The processor can receive data collected by the monitoring mechanism 4 in real time, process the data, and then display the data as a curve in real time through the display 7, so that the tester can judge whether the data is qualified or unqualified based on the curve.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
