Description

Technical Field

[0001] This application relates to the field of battery testing technology, and in particular to a battery testing device and a battery testing method. Background Technology

[0002] In battery testing devices of related technologies, it is sometimes necessary to perform an insertion and connection operation between the plug of the battery testing device and the socket of the battery device. The success rate of insertion and connection has a significant impact on the efficiency of battery testing.

[0003] The above statements are for the purpose of providing background information in relation to this application only, and do not necessarily constitute prior art. Summary of the Invention

[0004] The purpose of this application is to provide a battery testing device and a battery testing method, which aim to improve the insertion success rate during battery testing and thus improve testing efficiency.

[0005] To achieve the above objectives, a first aspect of this application provides a battery testing apparatus, comprising: an overall frame; a robotic arm including a connecting end and a free end disposed opposite to each other, the connecting end being connected to the overall frame; a testing frame connected to the overall frame; a plugging device disposed on the testing frame, including a plug, the plugging device further comprising a plug driving device for driving the plug to move relative to the testing frame and / or the battery testing apparatus including a testing frame driving device for driving the testing frame to move relative to the overall frame, and the plug being positioned in a mating position opposite to the socket of the battery pack to be tested, such that the plug can only move along the insertion and removal directions toward and away from the socket; and an operating mechanism disposed at the free end of the robotic arm, configured to hold the plug in the mating position under the drive of the robotic arm and insert the plug into the socket along the insertion and removal directions.

[0006] By connecting the robotic arm to the overall frame of the device, the insertion device also includes a plug drive mechanism for moving the plug relative to the test frame and / or a test frame drive mechanism for moving the test frame relative to the overall frame of the device. An operating mechanism is located at the free end of the robotic arm. The operating mechanism holds the plug in the insertion position and inserts it into the socket along the insertion / removal direction. During the insertion process, the robotic arm remains stably positioned on the overall frame of the device, and essentially only requires force to be applied to the plug along the insertion / removal direction. This enables precise insertion of the plug into the socket of the battery pack under test, improving the accuracy and success rate of plug-to-socket connection, thereby increasing the testing efficiency of the battery testing device. Furthermore, inserting the plug into the socket via the operating mechanism offers higher consistency and reliability than manual insertion, thus improving the automation level of the battery testing device.

[0007] In some embodiments of the battery testing apparatus, the connecting end of the robotic arm is movably connected to the overall frame of the apparatus.

[0008] By setting the connecting end of the robotic arm to be movably connected to the overall frame of the device, the range of motion of the robotic arm can be increased, enabling the battery testing device to adapt to different battery pack models and different testing scenarios, thereby improving the applicability of the battery testing device.

[0009] In some embodiments of the battery testing apparatus, the battery testing apparatus further includes a robotic arm track assembly, the connecting end of the robotic arm being movably connected to the overall frame of the apparatus via the robotic arm track assembly.

[0010] By setting up a robotic arm track assembly, the connecting end of the robotic arm can be movably connected to the overall frame of the device through the robotic arm track assembly. This not only increases the range of motion of the robotic arm, but also helps to improve the stability and accuracy of the robotic arm during movement, thereby improving the accuracy and success rate of plug and socket connection.

[0011] In some embodiments of the battery testing apparatus, the robotic arm track assembly includes: a first robotic arm track extending along a first horizontal direction, with the connecting end of the robotic arm reciprocatingly disposed on the first robotic arm track; and a second robotic arm track connected to the overall frame of the apparatus, extending along a second horizontal direction perpendicular to the first direction, with the first robotic arm track reciprocatingly disposed on the second robotic arm track.

[0012] By setting a first robotic arm track extending horizontally along a first horizontal direction and a second robotic arm track extending horizontally along a second direction perpendicular to the first direction, the robotic arm can achieve precise movement within a horizontal range, enabling the operating mechanism to perform plug-in and socket connection operations at any position within the test area. Furthermore, the track structure employing the first and second robotic arm tracks helps ensure the stability and accuracy of the robotic arm's movement, thereby improving the accuracy and success rate of plug-in and socket connection.

[0013] In some embodiments of the battery testing apparatus, the robotic arm is a six-axis robotic arm.

[0014] The robotic arm adopts a six-axis design, which provides greater freedom of movement, making it easier to adjust the angle and position of the operating mechanism and adapt to more complex usage scenarios, thereby improving the adaptability and reliability of the battery testing device.

[0015] In some embodiments of the battery testing apparatus, the plug drive device includes a plug mounting base, which is mounted on a test frame. The plug is mounted on the plug mounting base and is reciprocally movable relative to the plug mounting base along the insertion / removal direction.

[0016] By setting a plug mounting base, and allowing the plug to reciprocate relative to the mounting base along the insertion / removal direction, the degree of freedom of movement of the plug relative to the mounting base in other unnecessary directions is effectively restricted. This helps reduce insertion failures caused by angular deviations and minimizes damage to the plug and socket, thereby improving the accuracy and success rate of plug-to-socket connections, increasing the testing efficiency of the battery testing device, and extending the service life of the battery testing device.

[0017] In some embodiments of the battery testing apparatus, a plug mounting base is movably mounted on the test frame.

[0018] By setting a plug mounting base that can be movably mounted on the test frame, the position of the plug can be adjusted to ensure that the plug and socket are aligned along the insertion direction, thereby improving the accuracy and success rate of plug and socket insertion.

[0019] In some embodiments of the battery testing apparatus, the plug drive device further includes a base track assembly, through which the plug mounting base is movably connected to the test frame.

[0020] By setting up a base track assembly, the plug mounting base can move stably via the base track assembly, which helps to improve the stability and accuracy of the plug mounting base during movement, thereby improving the accuracy and success rate of plug-socket connection.

[0021] In some embodiments of the battery testing apparatus, the base track assembly includes: a first base track, the extension direction of the first base track being perpendicular to the insertion / removal direction, and a plug mounting base being reciprocally disposed on the first base track; and a second base track, the second base track being connected to the test frame, and the extension direction of the second base track being the same as the insertion / removal direction, and the first base track being reciprocally disposed on the second base track.

[0022] By setting the first base track and the second base track, the plug mounting base can be precisely adjusted in the insertion and removal direction, so that the distance between the plug and the socket to be inserted in the vertical direction is suitable for the plug to be inserted into the socket. It also enables the plug mounting base to be precisely adjusted in the direction perpendicular to the insertion and removal direction, thereby aligning the plug and the socket along the insertion direction, which helps to improve the accuracy and success rate of plug and socket insertion.

[0023] In some embodiments of the battery testing apparatus, the plug-in device further includes a base locking device configured to lock the relative position of the plug mounting base and the first base track; and / or the plug-in device further includes a track locking device configured to lock the relative position of the first base track and the second base track.

[0024] By incorporating a base locking device, the plug mounting base and the first base track are locked in position after precise alignment, facilitating smooth insertion of the plug into the socket and improving the accuracy and success rate of plug-socket connection. Similarly, by incorporating a track locking device, the first and second base tracks are locked in position after precise alignment, further facilitating smooth insertion of the plug into the socket and improving the accuracy and success rate of plug-socket connection.

[0025] In some embodiments of the battery testing apparatus, the plugging device further includes an auxiliary plugging / unplugging device mounted on the plug mounting base and connected to the plug drive, configured to pull the plug out of the socket and / or assist the operating mechanism to insert the plug into the socket.

[0026] By incorporating an auxiliary insertion / removal device, which is mounted on the plug mounting base and connected to the plug drive, the plug can be automatically removed from the socket, thereby improving the automation level and testing efficiency of the battery testing device. Furthermore, the auxiliary insertion / removal device also assists the operating mechanism in inserting the plug into the socket, ensuring a smooth insertion process.

[0027] In some embodiments of the battery testing apparatus, the test frame is movably arranged relative to the overall frame of the apparatus along a vertical third direction. A test frame drive device is connected to the test frame drive and configured to drive the test frame to move along the third direction.

[0028] By setting up a test frame drive device connected to the test frame drive, the test frame can be reciprocated relative to the overall device frame along a vertical third direction under the drive of the test frame drive device. This facilitates the adjustment of the positional relationship between the battery pack and the operating mechanism in the vertical direction, thereby improving the accuracy of plug and socket connection. If the battery pack may interfere with the test frame and its mounted components when entering or exiting the battery testing device, the test frame drive device connected to the test frame drive also helps to avoid interference with the battery pack when entering or exiting the battery testing device. In addition, the test frame drive device connected to the test frame drive can also raise the test frame when manual intervention is required, switching the battery testing device to a semi-automatic mode, reserving space for manual plug-in / plug-out operations for another set of plugs, giving the battery testing device the ability to flexibly adapt to different operating conditions.

[0029] In some embodiments of the battery testing apparatus, the test frame drive device includes a screw and a screw drive mechanism. The screw is rotatably mounted on the overall frame of the apparatus and extends in a third direction; the test frame has a threaded hole, and the test frame is connected to the screw through the threaded hole. The screw drive mechanism is connected to the screw drive and is configured to drive the screw to rotate.

[0030] By setting up a screw and a screw drive mechanism, the test frame can reciprocate along a vertical third direction relative to the overall frame of the device, which facilitates accurate adjustment of the positional relationship between the battery pack and the operating mechanism in the vertical third direction.

[0031] In some embodiments of the battery testing apparatus, the battery testing apparatus further includes: a transport vehicle configured to transport the battery pack to the testing position of the battery testing apparatus; and a transport vehicle locking device configured to fix the transport vehicle relative to the overall frame of the apparatus.

[0032] By setting up a locking device on the transport vehicle, the battery pack can be locked in the test position by locking the transport vehicle, which helps to improve the certainty of the plug's position relative to the socket and the socket position when the plug is inserted, thereby improving the accuracy and success rate of plug-socket insertion.

[0033] In some embodiments of the battery testing apparatus, a camera is also included, which is disposed at the free end of the robotic arm and configured to take pictures of the position of the plug and socket for correction.

[0034] By setting up a camera, the position of the plug and socket can be photographed and corrected, thereby improving the accuracy of the plug and socket positioning, which in turn improves the accuracy and success rate of plug and socket connection, and helps to reduce damage to the plug and socket.

[0035] A second aspect of this application provides a battery testing method, comprising: moving a plug of a connector relative to a test frame on which the connector is mounted and / or moving the test frame on which the connector is mounted relative to the main frame of the device on which the test frame is mounted, and positioning the plug in a mating position opposite to the socket of a battery pack to be tested, such that the plug can only move along the insertion and removal directions toward and away from the socket; and having an operating mechanism mounted on a robotic arm, driven by the robotic arm mounted on the main frame of the device, hold the plug in the mating position and insert the plug into the socket along the insertion and removal directions.

[0036] By moving the plug of the connector relative to the test frame and / or moving the test frame relative to the overall frame of the device, and with the operating mechanism holding the plug in the mating position and inserting it into the socket along the insertion / removal direction, the plug can be accurately inserted into the socket of the battery pack under test. This improves the accuracy and success rate of plug-socket connection, thereby increasing the testing efficiency of the battery testing device. Furthermore, inserting the plug into the socket via the operating mechanism offers higher consistency and reliability than manual insertion, thus enhancing the automation level of the battery testing device.

[0037] In some embodiments of the battery testing method, the method includes: adjusting the position of the robotic arm on the overall frame of the device.

[0038] By adjusting the position of the robotic arm on the overall frame of the device, the range of motion of the robotic arm can be increased, enabling the battery testing device to adapt to different battery pack models and different testing scenarios, thereby improving the applicability of the battery testing device.

[0039] In some embodiments of the battery testing method, the method further includes using an auxiliary plugging / unplugging device of the plugging device to pull the plug out of the socket and / or an auxiliary operating mechanism to insert the plug into the socket.

[0040] The auxiliary plugging / unplugging device of the connector can automatically remove the plug from the socket, thereby improving the automation level and testing efficiency of the battery testing device. The auxiliary plugging / unplugging device also assists the operating mechanism in inserting the plug into the socket, ensuring smooth insertion.

[0041] In some embodiments of the battery testing method, moving the test frame with the mounting connector relative to the overall frame of the device on which the test frame is mounted includes adjusting the position of the test frame on the overall frame of the device along the vertical third direction Z.

[0042] By adjusting the position of the test frame along the vertical Z-direction on the overall frame of the device, the positional relationship between the battery pack and the operating mechanism can be adjusted vertically, thereby improving the accuracy of plug and socket connection. If the battery pack may interfere with the test frame and its mounted components when entering or exiting the battery testing device, a test frame drive device connected to the test frame drive also helps to avoid interference with the battery pack during entry and exit. Furthermore, the test frame drive device connected to the test frame drive also allows the test frame to be raised when manual intervention is required, switching the battery testing device to a semi-automatic mode. This preserves space for manual plug-in / plug-out operations for another set of plugs, giving the battery testing device the ability to flexibly adapt to different operating conditions.

[0043] In some embodiments of the battery testing method, the method also includes taking pictures of the positions of the plug and socket using a camera mounted on a robotic arm for correction.

[0044] By using a camera mounted on the robotic arm to photograph and correct the position of the plug and socket, the accuracy of the plug and socket positioning can be improved, thereby increasing the accuracy and success rate of plug and socket connection and reducing damage to the plug and socket.

The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0060] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0061] In the description of this application, it should be understood that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0062] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0064] Unless otherwise required by the content, throughout the following description, the word “including” and its variations, such as “comprising” and “having”, will be interpreted in an open-ended, inclusive sense, that is, as “including but not limited to”.

[0065] In this application, "multiple" means two or more (including two), and similarly, "multiple groups" means two or more (including two groups).

[0066] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0067] As described in the background section, in battery testing devices of related technologies, it is sometimes necessary to perform an insertion and connection operation between the plug of the battery testing device and the socket of the battery device. Existing battery testing devices use mobile insertion and connection equipment to operate the plug. Due to positioning deviation, the success rate of automatic insertion is low, and frequent failures such as jamming and misalignment occur, affecting the continuity of system operation. Alternatively, manual intervention is required to complete the insertion and connection operation, resulting in long test cycles and low utilization of the battery testing device, which makes it difficult to meet the needs of large-scale production scenarios. Therefore, the insertion success rate has a significant impact on the efficiency of battery testing.

[0068] Based on this, this application proposes a battery testing device. By setting up a robotic arm connected to the overall frame of the device, the insertion device further includes a plug driving device for driving the plug to move relative to the test frame and / or the battery testing device includes a test frame driving device for driving the test frame to move relative to the overall frame of the device. The operating mechanism is set at the free end of the robotic arm, which can realize the accurate insertion of the plug into the socket of the battery pack to be tested along the insertion and removal direction, which is conducive to improving the accuracy and success rate of plug and socket insertion, thereby improving the testing efficiency of the battery testing device.

[0069] like Figures 1 to 10 As shown, the battery testing device of this application embodiment includes: a device frame 1; a robotic arm 2, including a connecting end 22 and a free end 21 disposed opposite to each other, the connecting end 22 being connected to the device frame 1; a test frame 3, connected to the device frame 1; a plugging device 4, disposed on the test frame 3, including a plug 41, the plugging device 4 further including a plug driving device 42 for driving the plug 41 to move relative to the test frame 3 and / or the battery testing device including a test frame driving device 9 for driving the test frame 3 to move relative to the device frame 1, and the plug 41 can be positioned in a mating position opposite to the socket B1 of the battery pack B to be tested, so that the plug 41 can only move along the insertion and removal directions toward and away from the socket B1; an operating mechanism 5, disposed on the free end 21 of the robotic arm 2, configured to hold the plug 41 in the mating position under the drive of the robotic arm 2 and insert the plug 41 into the socket B1 along the insertion and removal direction.

[0070] The robotic arm 2 is connected to the main frame 1 via its connecting end 22. The insertion device 4 also includes a plug drive device 42 that drives the plug 41 to move relative to the test frame 3, and / or a test frame drive device 9 that drives the test frame 3 to move relative to the main frame 1. An operating mechanism 5 is located at the free end 21 of the robotic arm 2. The operating mechanism 5 holds the plug 41 in the insertion position and inserts it into the socket B1 along the insertion / removal direction. During the insertion of the plug 41 into the socket B1, the robotic arm 2 remains stably positioned on the main frame 1. It essentially only needs to apply force to the plug 41 along the insertion / removal direction, enabling precise insertion of the plug 41 into the socket B1 of the battery pack B to be tested. This improves the accuracy and success rate of the plug 41 insertion into the socket B1, thereby increasing the testing efficiency of the battery testing device. Furthermore, inserting the plug 41 into the socket B1 via the operating mechanism 5 provides higher consistency and reliability than manual insertion, thus improving the automation level of the battery testing device.

[0071] like Figures 2 to 4 As shown, in some embodiments of the battery testing apparatus, the connecting end 22 of the robotic arm 2 is movably connected to the overall frame 1 of the apparatus.

[0072] By setting the connecting end 22 of the robotic arm 2 to be movably connected to the overall frame 1 of the device, the range of motion of the robotic arm 2 is increased, enabling the battery testing device to adapt to different models of battery packs B and different testing scenarios, thereby improving the applicability of the battery testing device.

[0073] like Figures 2 to 4 As shown, in some embodiments of the battery testing apparatus, the battery testing apparatus further includes a robotic arm track assembly 8, and the connecting end 22 of the robotic arm 2 is movably connected to the overall frame 1 of the apparatus through the robotic arm track assembly 8.

[0074] By setting up the robotic arm track assembly 8, the connecting end 22 of the robotic arm 2 is movably connected to the overall frame 1 of the device through the robotic arm track assembly 8. This not only increases the range of motion of the robotic arm 2, but also helps to improve the stability and accuracy of the robotic arm 2 during movement, thereby improving the accuracy and success rate of plug 41 and socket B1 connection.

[0075] like Figures 2 to 4 As shown, in some embodiments of the battery testing apparatus, the robotic arm track assembly 8 includes: a first robotic arm track 81 extending along a horizontal first direction X, with the connecting end 22 of the robotic arm 2 reciprocally disposed on the first robotic arm track 81; and a second robotic arm track 82 connected to the overall frame 1 of the apparatus, extending along a horizontal second direction Y perpendicular to the first direction X, with the first robotic arm track 81 reciprocally disposed on the second robotic arm track 82.

[0076] By setting a first robotic arm track 81 extending horizontally along a first horizontal direction X and a second robotic arm track 82 extending horizontally along a second horizontal direction Y perpendicular to the first direction X, the robotic arm 2 can achieve precise movement within a horizontal range. This allows the operating mechanism 5 to perform the insertion and connection operation of the plug 41 and the socket B1 at any position within the test area. Furthermore, the track structure of the first robotic arm track 81 and the second robotic arm track 82 helps ensure the stability and accuracy of the robotic arm 2 during movement, thereby improving the accuracy and success rate of the insertion and connection of the plug 41 and the socket B1.

[0077] like Figure 3 As shown, in some embodiments of the battery testing apparatus, robotic arm 2 is a six-axis robotic arm.

[0078] The robotic arm 2 adopts a six-axis robotic arm form, which has a higher degree of freedom and is conducive to adjusting the angle and position of the operating mechanism 5. It is also conducive to adapting to more complex usage scenarios, thereby improving the adaptability and reliability of the battery testing device.

[0079] like Figures 5 to 6As shown, in some embodiments of the battery testing apparatus, the plug driving device 42 further includes a plug mounting base 421, which is mounted on the test frame 3. The plug 41 is mounted on the plug mounting base 421 and is reciprocally movable relative to the plug mounting base 421 along the insertion / removal direction.

[0080] By setting the plug mounting base 421, and setting the plug 41 to be reciprocally movable relative to the plug mounting base 421 along the insertion and removal direction, the degree of freedom of movement of the plug 41 relative to the plug mounting base 421 in other unnecessary directions is effectively restricted. This helps to reduce insertion failure due to angular deviation and to reduce damage to the plug 41 and the socket B1. As a result, it helps to improve the accuracy and success rate of plug 41 and socket B1 insertion, improve the testing efficiency of the battery testing device, and enhance the service life of the battery testing device.

[0081] like Figures 5 to 6 As shown, in some embodiments of the battery testing apparatus, the plug mounting base 421 is movably mounted on the test frame 3.

[0082] By setting the plug mounting base 421 to be movably mounted on the test frame 3, it is convenient to adjust the position of the plug 41 and ensure that the plug 41 and the socket B1 are aligned in the insertion direction, thereby improving the accuracy and success rate of plug 41 and socket B1 insertion.

[0083] like Figures 5 to 6 As shown, in some embodiments of the battery testing apparatus, the plug drive device 42 further includes a base track assembly 422, and the plug mounting base 421 is movably connected to the test frame 3 via the base track assembly 422.

[0084] By setting the base track assembly 422, the plug mounting base 421 can move stably through the base track assembly 422, which helps to improve the stability and movement accuracy of the plug mounting base 421 during the movement process, thereby improving the accuracy and success rate of plug 41 and socket B1 insertion.

[0085] like Figures 5 to 6 As shown, in some embodiments of the battery testing apparatus, the base track assembly 422 includes: a first base track 4221, the extension direction of the first base track 4221 being perpendicular to the insertion / removal direction, and a plug mounting base 421 being reciprocally movably disposed on the first base track 4221; and a second base track 4222, the second base track 4222 being connected to the test frame 3, and the extension direction of the second base track 4222 being the same as the insertion / removal direction, and the first base track 4221 being reciprocally movably disposed on the second base track 4222.

[0086] By setting the first base track 4221 and the second base track 4222, the plug mounting base 421 can be precisely adjusted in the insertion and removal direction, so that the distance between the plug 41 and the socket B1 to be inserted in the vertical direction is suitable for the plug 41 to be inserted into the socket B1. It also enables the plug mounting base 421 to be precisely adjusted in the direction perpendicular to the insertion and removal direction, thereby aligning the plug 41 and the socket B1 in the insertion direction, which helps to improve the accuracy and success rate of plug 41 and socket B1 insertion.

[0087] like Figures 5 to 6 As shown, in some embodiments of the battery testing apparatus, the plug-in device 4 further includes a base locking device 45, which is configured to lock the relative position of the plug mounting base 421 and the first base track 4221; and / or the plug-in device 4 further includes a track locking device, which is configured to lock the relative position of the first base track 4221 and the second base track 4222.

[0088] By setting the base locking device 45, the plug 41 can be precisely aligned with the socket B1, and the relative position of the plug mounting base 421 and the first base track 4221 can be locked, which facilitates the smooth insertion of the plug 41 into the socket B1 and improves the accuracy and success rate of plug 41 and socket B1 connection.

[0089] By setting a track locking device, the relative positions of the first base track 4221 and the second base track 4222 can be locked after the plug 41 and the socket B1 are precisely aligned, thereby facilitating the smooth insertion of the plug 41 into the socket B1 and improving the accuracy and success rate of plug 41 and socket B1 connection.

[0090] like Figures 5 to 6 As shown, in some embodiments of the battery testing apparatus, the plugging device 4 further includes an auxiliary plugging and unplugging device 44, which is mounted on the plug mounting base 421 and drivenly connected to the plug 41, and is configured to pull the plug 41 out of the socket B1 and / or the auxiliary operating mechanism 5 to insert the plug 41 into the socket B1.

[0091] By providing an auxiliary insertion / removal device 44, which is mounted on the plug mounting base 421 and drivenly connected to the plug 41, the plug 41 can be automatically removed from the socket B1, thereby improving the automation level and testing efficiency of the battery testing device. Furthermore, the auxiliary insertion / removal device 44 can also assist the operating mechanism 5 in inserting the plug 41 into the socket B1, ensuring that the operating mechanism 5 can smoothly insert the plug 41 into the socket B1.

[0092] like Figures 1 to 3As shown, in some embodiments of the battery testing apparatus, the test frame 3 is arranged to reciprocate relative to the overall frame 1 along a vertical third direction Z. A test frame drive device 9 is drivenly connected to the test frame 3 and configured to drive the test frame 3 to move along the third direction Z.

[0093] By setting up a test frame drive device 9 connected to the test frame 3, the test frame 3 can be reciprocated relative to the overall frame 1 in the vertical third direction Z under the drive of the test frame drive device 9. This facilitates the adjustment of the positional relationship between the battery pack B and the operating mechanism 5 in the vertical direction, thereby improving the accuracy of the insertion of the plug 41 and the socket B1. If the battery pack B may interfere with the test frame 3 and its mounted components when entering or exiting the battery testing device, the test frame drive device 9 connected to the test frame 3 also helps to avoid interference with the battery pack B when entering or exiting the battery testing device. In addition, the test frame drive device 9 connected to the test frame 3 can also raise the test frame 3 when manual intervention is required, switching the battery testing device to a semi-automatic mode, reserving space for manual insertion and removal operations for another set of plugs, giving the battery testing device the ability to flexibly adapt to different working conditions.

[0094] like Figure 1 and Figure 5 As shown, in some embodiments of the battery testing apparatus, the test frame drive device 9 includes a screw 91 and a screw drive mechanism 92. The screw 91 is rotatably mounted on the overall frame 1 of the apparatus and extends in the third direction Z; the test frame 3 is provided with a threaded hole 32, and the test frame 3 is connected to the screw 91 through the threaded hole 32. The screw drive mechanism 92 is drivenly connected to the screw 91 and is configured to drive the screw 91 to rotate.

[0095] By setting screw 91 and screw drive mechanism 92, the test frame 3 can reciprocate relative to the overall frame of the device along the vertical third direction Z, which facilitates the accurate adjustment of the positional relationship between battery pack B and operating mechanism 5 in the vertical third direction Z.

[0096] like Figure 7 As shown, in some embodiments of the battery testing apparatus, the battery testing apparatus further includes: a transport vehicle 6, configured to transport the battery pack B to the testing position of the battery testing apparatus; and a transport vehicle locking device 7, configured to fix the transport vehicle 6 relative to the overall frame 1 of the apparatus.

[0097] By setting the transport vehicle locking device 7, the battery pack B can be locked in the test position by locking the transport vehicle 6, which helps to improve the certainty of the position adjustment of the plug 41 relative to the socket B1 and the position of the socket B1 when the plug 41 is plugged in, thereby improving the accuracy and success rate of plug 41 plugging in the socket B1.

[0098] In some embodiments of the battery testing apparatus, a camera is also included, which is located at the free end 21 of the robotic arm 2 and configured to take pictures and correct the position of the plug 41 and the socket B1.

[0099] By setting up a camera, the positions of plug 41 and socket B1 can be photographed and corrected, thereby further improving the accurate positioning of plug 41 and socket B1, thus improving the accuracy and success rate of plug 41 and socket B1 connection, and helping to reduce damage to plug 41 and socket B1.

[0100] like Figures 1 to 10 As shown, this application embodiment also provides a battery testing method, including: moving the plug 41 of the connector 4 relative to the test frame 3 on which the connector 4 is mounted and / or moving the test frame 3 on which the connector 4 is mounted relative to the main frame 1 of the device on which the test frame 3 is mounted, and positioning the plug 41 in a mating position opposite to the socket B1 of the battery pack B to be tested, so that the plug 41 can only move along the insertion and removal direction toward and away from the socket B1; and having the operating mechanism 5 provided on the robotic arm 2 hold the plug 41 in the mating position under the drive of the robotic arm 2 provided on the main frame 1 of the device and insert the plug 41 into the socket B1 along the insertion and removal direction.

[0101] By moving the plug 41 of the insertion device 4 relative to the test frame 3 and / or moving the test frame 3 relative to the overall frame 1 of the device, and with the operating mechanism 5 holding the plug 41 in the insertion position and inserting the plug 41 into the socket B1 along the insertion / removal direction, the plug 41 can be accurately inserted into the socket B1 of the battery pack B to be tested. This improves the accuracy and success rate of the plug 41 and socket B1 connection, thereby increasing the testing efficiency of the battery testing device. Furthermore, inserting the plug 41 into the socket B1 via the operating mechanism 5 provides higher consistency and reliability than manual insertion, thus improving the automation level of the battery testing device.

[0102] In some embodiments of the battery testing method, the method includes: adjusting the position of the robotic arm 2 on the overall frame 1 of the device.

[0103] By adjusting the position of the robotic arm 2 on the overall frame 1 of the device, the range of motion of the robotic arm 2 can be increased, enabling the battery testing device to adapt to different models of battery packs B and different testing scenarios, thereby improving the applicability of the battery testing device.

[0104] like Figures 5 to 6 As shown, in some embodiments of the battery testing method, the plug 41 is pulled out of the socket B1 by the auxiliary plugging and unplugging device 44 of the plugging device 4 and / or the plug 41 is inserted into the socket B1 by the auxiliary operating mechanism 5.

[0105] The auxiliary insertion / removal device 44 of the insertion device 4 can automatically remove the plug 41 from the socket B1, thereby improving the automation level and testing efficiency of the battery testing device. The auxiliary insertion / removal device 44 also uses the auxiliary operating mechanism 5 to insert the plug 41 into the socket B1, ensuring that the operating mechanism 5 smoothly inserts the plug 41 into the socket B1.

[0106] In some embodiments of the battery testing method, moving the test frame 3 with the mounting plug-in device 4 relative to the overall device frame 1 with the test frame 3 mounted includes adjusting the position of the test frame 3 on the overall device frame 1 along the vertical third direction Z.

[0107] By adjusting the position of the test frame 3 along the vertical third direction Z on the overall frame 1 of the device, it is beneficial to adjust the positional relationship between the battery pack B and the operating mechanism 5 in the vertical direction, thereby improving the accuracy of the insertion of the plug 41 and the socket B1. If the battery pack B may interfere with the test frame 3 and the components mounted on it when entering or exiting the battery testing device, the test frame drive device 9, which is driven and connected to the test frame 3, also helps to avoid interference with the battery pack B when entering or exiting the battery testing device. In addition, the test frame drive device 9, which is driven and connected to the test frame 3, can also raise the test frame 3 when manual intervention is required, so that the battery testing device switches to a semi-automatic mode, leaving space for manual insertion and removal operations for another set of plugs, giving the battery testing device the ability to flexibly adapt to different working conditions.

[0108] In some embodiments of the battery testing method, the method also includes taking pictures of the positions of the plug 41 and the socket B1 using a camera set on the robotic arm 2 for correction.

[0109] By taking pictures of the positions of plug 41 and socket B1 using a camera mounted on robotic arm 2, the accuracy of the positioning of plug 41 and socket B1 can be improved, thereby increasing the accuracy and success rate of plug 41 and socket B1 connection and reducing damage to plug 41 and socket B1.

The X-axis position locking device and the Y-axis position locking device can, for example, take the form of a friction element that includes pneumatic drive, similar to the base locking device 45 described later.

[0115] An operating mechanism 5 is located at the free end 21 of the robotic arm 2 and is configured to hold the plug 41 and insert the plug 41 into the socket B1. The operating mechanism 5 includes a connecting part 51 and a clamping part 52. The connecting part 51 is connected to the free end 21 of the robotic arm 2. The clamping part 52 includes two gripping fingers 521 for gripping the plug 41.

[0116] Test frame 3 and overall device frame 1 are aligned along the third direction Z (corresponding to...) Figure 1 It can be movably connected in the vertical direction.

[0117] The plug-in device 4 is disposed on the test frame 3. There can be multiple plug-in devices 4. In this embodiment, one plug-in device 4 is disposed on the inner side of each of the four sides of the test frame 3.

[0118] The plug-in device 4 includes a plurality of plugs 41 and a plug driving device 42.

[0123] In this embodiment, the base track assembly 422 includes two first base tracks 4221 arranged side-by-side at intervals.

The base locking device 45 may include, for example, a friction element that achieves relative position locking with the first base track 4221 through frictional engagement.

In this embodiment, the test frame drive device 9 includes four sets of screws 91 and screw drive mechanisms 92 respectively arranged at the four corners of the test frame 3.

[0127] The transport vehicle 6 is configured to transport the battery pack B to the test position of the battery testing apparatus. The transport vehicle locking device 7 is configured to fix the transport vehicle 6 relative to the overall frame 1 of the apparatus. In this embodiment, the transport vehicle locking device 7 can be mounted on a frame other than the test frame 3. In embodiments not shown, the transport vehicle locking device 7 can also be connected to the test frame 3. The transport vehicle locking device 7 can fix the transport vehicle 6 by clamping, plug-in connection, or other means.

[0128] The camera is set at the free end 21 of the robotic arm 2 and is configured to take pictures and correct the position of the plug 41 and the socket B1.

[0129] The following describes an exemplary battery testing method using a battery testing apparatus according to an embodiment of this application.

[0130] The transport vehicle 6 first transports the battery pack B to be tested to the testing position of the battery testing device. At this time, the test frame 3 is positioned above the battery pack B in the vertical direction to prevent obstruction of the battery pack B's movement. The battery pack B can be mounted on a carrier trolley, and the transport vehicle 6 transports the battery pack B via this carrier trolley. The transport vehicle 6 can be, for example, an AGV (Automated Guided Vehicle).

[0131] The transport vehicle locking device 7 locks the relative position of the transport vehicle 6 with respect to the overall frame of the device, thus fixing the battery pack B in the test position.

[0132] Adjust the position of the test frame 3 along the vertical third direction Z. The test frame 3 is lowered relative to the overall frame 1 along the vertical third direction Z so that each plug 41 is aligned with the socket B1 in the height direction.

[0133] The plug 41 of the connector 4 is moved relative to the test frame 3, and positioned in a mating position opposite to the socket B1 of the battery pack B to be tested. The position of each plug 41 along the insertion / removal direction and along a direction perpendicular to the insertion / removal direction is adjusted by the base track assembly 422, so that each plug 41 is aligned with the corresponding socket B1 in a horizontal direction perpendicular to the insertion / removal direction, and positioned in a mating position opposite to the socket B1 of the battery pack B to be tested.

[0134] The position of the robotic arm 2 on the overall frame 1 of the device is adjusted. The six-axis robotic arm moves to a preset position according to the position of the socket B1 of the battery pack B, driving the operating mechanism 5 located at the free end 21 of the six-axis robotic arm to a position where it can mate with the plug 41. Before the plug 41 is inserted into the socket B1, the position of the plug 41 and the socket B1 is photographed and corrected by a camera set on the robotic arm 2. During the correction process, the position of the plug 41 can be finely adjusted to ensure precise alignment with the socket B1. The gripping fingers 521 of the gripping part 52 grip the plug 41, and the six-axis robotic arm applies force to insert the plug 41 into the socket B1. During this process, the auxiliary insertion and removal device 44 corresponding to the plug 41 cooperates with the movement of the plug 41. If there are multiple plugs 41 that need to be inserted into multiple sockets B1 respectively, the six-axis robotic arm completes the insertion and removal operation with each plug 41 one by one.

[0135] Conduct tests. For example, an airtightness test, such as a helium test, is performed on battery pack B.

[0136] After the test is completed, the plug 41 is pulled out of the socket B1 using the auxiliary plugging / unplugging device 44 of the plugging device 4. The cylinders of each auxiliary plugging / unplugging device 44 pull out the corresponding plug 41 from the socket B1. The test frame 3 rises relative to the main frame 1 along the vertical third direction Z to avoid the battery pack B. The transport vehicle 6 carries the tested battery pack B away from the battery testing device.

The specific execution order of each step should be determined by its function and possible internal logic.

[0138] The description of the various embodiments above tends to emphasize the differences between the various embodiments. The similarities or similarities between them can be referred to, and for the sake of brevity, they will not be repeated here.

[0139] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this application or equivalent substitutions can be made to some technical features, all of which should be covered within the scope of the technical solutions claimed in this application.
