[0021] 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.

[0022] An automatic electrical measuring device 100 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0023] refer to Figures 1-9 According to an embodiment of the present invention, an automatic electrical testing device 100 is used to be electrically connected to a battery device 300 on a conveyor line 200 to detect the battery device 300. The bottom surface of the battery device 300 is provided with a battery interface 301 and the battery interface 301 faces downward. The automatic electrical testing device 100 is used to be disposed below the conveyor line 200.

[0024] For example, refer to Figure 1 , Figure 9 The battery device 300 has a skid 302 at its bottom, and a drive wheel 201 is provided on the conveyor line 200. The drive wheel 201 cooperates with the skid 302 to drive the battery device 300 along the extension direction of the conveyor line 200 (e.g., refer to...). Figure 1 The battery device 300 can move in the left and right directions. A position sensor is installed along the extension direction of the conveyor line 200 to accurately locate the position of the battery device 300 along the extension direction of the conveyor line 200. An opening 202 is provided on the conveyor line 200 corresponding to the position of the automatic electrical testing device 100, allowing the automatic electrical testing device 100 to pass through and connect to the battery interface 301 at the bottom of the battery device 300.

[0025] refer to Figures 1-3 The automatic electrical testing device 100 includes: a frame 10, a docking module 20, and a lifting mechanism 30.

[0026] For example, the lifting mechanism 30 can be a hydraulic lifting cylinder or an electric cylinder.

[0027] The docking module 20 is vertically and flexibly mounted on the frame 10. The docking module 20 includes a support plate 21, a docking component 22, and an adjustment mechanism 23. The docking component 22 includes a docking plate 221 and a detection interface 222 disposed on the docking plate 221. The detection interface 222 faces upward and is used for insertion into the battery interface 301 in the vertical direction. The docking plate 221 and the support plate 21 are movably connected via the adjustment mechanism 23, so that the docking component 22 is positioned relative to the support plate 21 along the width direction of the conveyor line 200 (e.g., reference...). Figure 1 The lifting mechanism 30 is movable in the forward and backward direction. The lifting mechanism 30 is installed on the frame 10, and the output end of the lifting mechanism 30 is connected to the support plate 21 to drive the docking module 20 to lift.

[0028] For example, in order to improve the reliability of battery device 300 conveying, the width of conveyor line 200 may be greater than the dimension of battery device 300 along the width direction of conveyor line 200.

[0029] The battery device 300 is often not precisely positioned along the width of the conveyor line 200. However, the docking module 20, driven by the lifting mechanism 30, moves upward relative to the frame 10, extending out of the opening 202 on the conveyor line 200 to dock with the battery device 300. Since the docking plate 221 and the support plate 21 are movably connected via the adjustment mechanism 23, allowing the docking component 22 to move relative to the support plate 21 along the width of the conveyor line 200, the docking component 22 can automatically move relative to the support plate 21 along the width of the conveyor line 200 during the docking process with the bottom of the battery device 300. This automatic adjustment and alignment of the docking component 22 along the width of the conveyor line 200 allows the detection interface 222 on the docking module 20 to automatically, quickly, and accurately dock with the battery interface 301 on the bottom surface of the battery device 300, eliminating the need for manual adjustment.

[0030] According to an embodiment of the present invention, the automatic electrical testing device 100 is positioned below the battery device 300 conveyor line 200, eliminating the need for battery flipping and enabling battery testing during the conveying process, thus improving testing efficiency. Simultaneously, the lifting mechanism 30 drives the docking module 20 to move upwards, and the adjustment mechanism 23 of the docking module 20 automatically adjusts the docking component 22 of the docking module 20 to the battery interface 301, achieving automatic docking between the automatic electrical testing device 100's detection interface 222 and the battery interface 301, eliminating manual docking operations and improving battery testing efficiency.

[0031] In some embodiments of the present invention, reference is made to Figures 4-8 The docking plate 221 is provided with an adjustment hole 2211, which extends through the docking plate 221 in the vertical direction. The adjustment mechanism 23 includes an adjustment rod 231 and an elastic support structure 232. The elastic support structure 232 is connected between the support plate 21 and the docking plate 221. The adjustment rod 231 extends in the vertical direction, with its lower end fixed to the support plate 21 and its upper end passing through the adjustment hole 2211. Along the width direction of the conveyor line 200, the adjustment rod 231 is movable relative to the adjustment hole 2211.

[0032] The elastic support structure 232 reduces the impact of the detection interface 222 on the battery interface 301 during the upward movement of the docking plate 221. Simultaneously, the elastic force of the elastic support structure 232 ensures that the detection interface 222 remains stably docked with the battery interface 301 throughout the detection process, improving battery detection efficiency. The adjusting rod 231 can move relative to the adjusting hole 2211 along the width direction of the conveyor line 200, enabling automatic adjustment of the detection interface 222 and battery interface 301 along the width direction of the conveyor line 200 during the upward movement, further improving battery detection efficiency.

[0033] In some embodiments of the present invention, reference is made to Figure 8 The adjustment hole 2211 is an elongated oval hole extending along the width direction of the conveyor line 200.

[0034] For example, the center of the oblong hole is rectangular, and the two ends of the long side of the rectangle are semicircles, with the diameter of the semicircles being the same as the diameter of the short side of the rectangle. The long side of the rectangle extends along the width direction of the conveyor line 200, and the length of the short side of the rectangle is the same as the diameter of the circular cross-section of the adjusting rod 231.

[0035] The elongated hole provides space for the adjustment rod 231 to move relative to the adjustment hole 2211 along the width of the conveyor line 200. It guides the movement of the adjustment rod 231 relative to the adjustment hole 2211 along the width of the conveyor line 200, ensuring that the detection interface 222 is automatically adjusted in the width of the conveyor line 200. This enables the detection interface 222 to automatically and accurately connect with the battery interface 301, improving battery detection efficiency.

[0036] In some embodiments of the present invention, reference is made to Figures 3-7 The elastic support structure 232 includes a spring 2321, which is sleeved on the outer periphery of the adjusting rod 231. The upper end of the spring 2321 is connected to the docking plate 221, and the lower end of the spring 2321 is connected to the support plate 21.

[0037] For example, spring 2321 has spring 2321 seats at both ends, the lower spring 2321 seat is fixedly connected to the support plate 21, and the upper spring 2321 seat is fixedly connected to the docking plate 221.

[0038] The spring 2321, fitted around the adjusting rod 231, reduces the impact of the detection interface 222 on the battery interface 301 during the upward movement of the docking plate 221. Simultaneously, the restoring force of the spring 2321 ensures that the detection interface 222 remains stably docked with the battery interface 301 throughout the detection process, improving battery detection efficiency.

[0039] In some embodiments of the present invention, reference is made to Figures 4-7 The adjustment mechanism 23 also includes a bearing 233, which is sleeved on the upper end of the adjustment rod 231 and fixed relative to the adjustment rod 231. The bearing 233 is located inside the adjustment hole 2211 and has a movable gap between the bearing 233 and the inner wall of the adjustment hole 2211 along the width direction of the conveyor line 200.

[0040] For example, fixing plates 2212 are provided at the corresponding positions of the adjustment holes 2211 at the upper and lower ends of the mating plate 221. The fixing plates 2212 clamp the bearing 233 in the adjustment holes 2211, so that the bearing 233 is relatively fixed relative to the adjustment rod 231.

[0041] A bearing 233 is fixedly arranged at the upper end of the adjustment rod 231, which can reduce the frictional wear between the adjustment rod 231 and the docking plate 221, and improve the service life of the automatic electrical testing device 100.

[0042] In some embodiments of the present invention, with reference to Figures 2-8 , a plurality of adjustment holes 2211 are arranged at intervals, and a plurality of adjustment mechanisms 23 are provided, which are respectively arranged in one-to-one correspondence with the plurality of adjustment holes 2211.

[0043] Providing a plurality of adjustment holes 2211 and the adjustment mechanisms 23 in one-to-one correspondence with the plurality of adjustment holes 2211 can better improve the stability of the movement of the docking plate 221 relative to the support plate 21 along the width direction of the conveying line 200, further prevent the docking plate 221 from shifting during the automatic adjustment process, and further improve the accuracy of the automatic docking between the testing interface 222 and the battery interface 301.

[0044] In some embodiments of the present invention, with reference to Figures 2-8 , the plurality of adjustment holes 2211 are divided into a plurality of adjustment hole 2211 groups, the plurality of adjustment hole 2211 groups are arranged at intervals along the extending direction of the conveying line 200, and each adjustment hole 2211 group includes a plurality of adjustment holes 2211 arranged at intervals along the width direction of the conveying line 200.

[0045] For example, four testing interfaces 222 distributed in a "field" shape are arranged on the docking plate 221. The four testing interfaces 221 form three gaps on the docking plate 221 along the extending direction of the conveying line 200, each gap is provided with one adjustment hole 2211 group, and each adjustment hole 2211 group includes a plurality of adjustment holes 2211 arranged at intervals along the width direction of the conveying line 200.

[0046] Arranging a plurality of adjustment hole 2211 groups along the extending direction of the conveying line 200, and each adjustment hole 2211 group is provided with a plurality of adjustment holes 2211, which can better improve the reliability of the movement of the docking plate 221 relative to the support plate 21 along the width direction of the conveying line 200, further prevent the docking plate 221 from shifting during the automatic adjustment process, and further improve the accuracy of the automatic docking between the testing interface 222 and the battery interface 301.

[0047] In some embodiments of the present invention, with reference to Figures 2-8 , a plurality of testing interfaces 222 are provided, the plurality of testing interfaces 222 are divided into a plurality of testing interface 222 groups, each testing interface 222 group includes one testing interface 222 or a plurality of testing interfaces 222 arranged at intervals along the width direction of the conveying line 200, and the testing interface 222 group is located between two adjacent adjustment hole 2211 groups.

[0048] For example, the docking plate 221 is provided with two sets of detection interfaces 222, and each set of detection interfaces 222 has two detection interfaces 222 along the width direction of the conveyor line 200. The number of sets of detection interfaces 222 and the number of detection interfaces 222 in each set of detection interfaces 222 can be adjusted according to actual detection needs.

[0049] Each set of detection interfaces 222 is located between two adjacent sets of adjustment holes 2211, which can further improve the docking accuracy of the detection interfaces 222 and further improve the docking accuracy of the detection interfaces 222 and the battery interface 301 along the width direction of the conveyor line 200.

[0050] In some embodiments of the present invention, reference is made to Figures 2-3 The docking component 22 also includes a guide mechanism 223, which is located on the docking plate 221. The guide mechanism 223 is used to contact and cooperate with the bottom surface of the battery device 300 to guide the automatic electrical testing device 100 to be positioned along the width direction of the conveyor line 200.

[0051] The guide mechanism 223 can automatically guide the automatic electrical testing device 100 to contact and cooperate with the bottom surface of the battery device 300, further improving the docking efficiency and accuracy of the testing interface 222 and the battery interface 301.

[0052] In some embodiments of the present invention, reference is made to Figure 9 The bottom surface of the battery device 300 has a mating groove 303. In the mating state, at least a portion of the mating component 22 is located within the mating groove 303. For example, at least the detection interface 222 of the mating component 22 is located within the mating groove 303 and connected to the battery interface 301.

[0053] refer to Figure 2-3 The guiding mechanism 223 includes multiple guide blocks. These guide blocks are distributed at both ends of the mating plate 221 along the width direction of the conveyor line 200. Each guide block has a guide surface 2231. The two ends of the mating plate 221 along the width direction of the conveyor line 200 are first ends. The guide surface 2231 extends upwards at an angle in the direction from the first ends to the center of the mating plate 221. At least a portion of the projection of the guide surface 2231 onto the horizontal plane lies within the projection of the mating groove 303 onto the horizontal plane.

[0054] For example, the guiding mechanism 223 has two guide blocks, one at each end of the docking plate 221 along the width direction of the conveyor line 200. It has a guide surface 2231 that gradually slopes upwards towards the center of the docking plate 221. During the ascent of the docking plate 221, it engages with the edge of the mating groove 303 on the bottom surface of the battery device 300, enabling automatic guidance and adjustment of the docking plate 221 along the width direction of the conveyor line 200.

[0055] The guide blocks are set at both ends of the docking plate 221 along the width direction of the conveyor line 200, and at least part of the projection of the guide surface 2231 of the guide block on the horizontal plane is located within the projection of the mating groove 303 on the horizontal plane. They can guide, center and position the docking component 22 along the width direction of the conveyor line 200, so that the position adjustment of the docking component 22 in the width direction of the conveyor line 200 is faster and more accurate. This allows the detection interface 222 on the docking component 22 to better, faster and more accurately dock with the battery interface 301 at the bottom of the battery device 300.

[0056] According to a second aspect of the present invention, a battery testing system includes a conveyor line 200 and an automatic electrical testing device 100, wherein the automatic electrical testing device 100 is any of the automatic electrical testing devices 100 described above, and the automatic electrical testing device 100 is located below the conveyor line 200.

[0057] For example, a drive wheel 201 is provided on the conveyor line 200. The drive wheel 201 cooperates with the skid 302 provided at the bottom of the battery device 300 to drive the battery device 300 to move along the extension direction of the conveyor line 200. A position sensor is provided along the extension direction of the conveyor line 200 to accurately locate the position of the battery device 300 along the extension direction of the conveyor line 200.

[0058] For example, the conveyor line 200 is provided with an opening 202 at the position corresponding to the automatic electrical testing device 100, through which the automatic electrical testing device 100 can pass. The automatic electrical testing device 100 can move upward through the opening 202, so that the detection interface 222 is connected to the battery interface 301 at the bottom of the battery device 300.

[0059] According to the battery testing system of this embodiment, the automatic electrical testing device 100 is positioned below the battery device 300 conveyor line 200, eliminating the need for battery flipping and enabling battery testing during the conveying process, thus improving testing efficiency. Simultaneously, the lifting mechanism 30 drives the docking module 20 to move upwards, and the adjustment mechanism 23 of the docking module 20 automatically adjusts the docking component 22 of the docking module 20 to the battery interface 301, achieving automatic docking between the automatic electrical testing device 100's testing interface 222 and the battery interface 301, eliminating manual docking operations and improving battery testing efficiency.
