[0043] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following will further describe the solution of the present utility model. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0044] Many specific details are set forth in the following description in order to provide a thorough understanding of the present utility model, but the present utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0045] Combined with Figures 1 to 4 As shown, the detection fixture provided by the embodiment of the present utility model includes a base 1, a clamping portion 2 and a supporting portion 3. The clamping portion 2 is arranged on the base 1, and a clamping cavity 21 for clamping a component 4 to be detected is formed on the clamping portion 2. Specifically, the shape of the clamping cavity 21 matches at least part of the shape of the component 4 to be detected, so that the component 4 to be detected can be clamped in the clamping cavity 21 to ensure the clamping effect of the component 4 to be detected. For example, the component 4 to be detected can be a soft-pack battery cell. At this time, the clamping cavity 21 should be in a sheet-like structure so that the clamping portion 2 can clamp both sides of the soft-pack battery cell. The supporting portion 3 is used to support the component 4 to be detected clamped by the clamping portion 2 to limit the position of the component 4 to be detected in the clamping cavity 21, ensure the stability of the component 4 to be detected and the accuracy of positioning, and thus ensure the detection effect. The detection end 41 of the component 4 to be detected supported by the supporting portion 3 extends out of the clamping portion 2 and is away from the base 1. In other words, the detection space of the component 4 to be detected is increased by the detection end 41 of the component 4 to be detected supported by the supporting portion 3.

[0046] Based on the detection fixture provided by the present utility model, the component 4 to be detected is clamped by the clamping portion 2, and the component 4 to be detected is supported by the supporting portion 3 to ensure the stability of the positioning of the component 4 to be detected, avoid the phenomenon that the component 4 to be detected shakes during the detection process, ensure the detection effect, and the supporting portion 3 supports the detection end 41 of the component 4 to be detected at a position away from the base 1, increases the detection space of the component 4 to be detected, facilitates the detection of the detection piece, and avoids the phenomenon that the detection piece scratches the base 1, ensuring the smooth progress of the detection.

[0047] The supporting portion 3 of the present application includes a first supporting block 31 and a second supporting block 32. The first supporting block 31 and the second supporting block 32 are respectively arranged at both ends of the clamping cavity 21 and cooperate with the clamping cavity 21 to form a fixed space for supporting and limiting the component 4 to be detected.

[0048] In this design method, the component 4 to be detected can be limited by the first support block 31 and the second support block 32 to maintain the position of the component 4 to be detected. Furthermore, the detection end 41 of the component 4 to be detected can be supported at a position away from the base 1. In some embodiments, the component 4 to be detected supported by the support portion 3 extends in the vertical direction. At this time, the support portion 3 supports both sides of the component 4 to be detected in the width direction. Specifically, the first support block 31 and the second support block 32 respectively support both sides of the component 4 to be detected to cooperate with the clamping cavity 21 to limit the position of the component 4 to be detected, so that the top of the component 4 to be detected extends out of the clamping cavity 21, that is, the detection end 41 of the component 4 to be detected extends out of the clamping cavity 21.

[0049] In some other embodiments, in combination with Figure 1 and Figure 2 as shown, the first support block 31 is arranged on the base 1 and is used to support the bottom of the component 4 to be detected. The second support block 32 is arranged on the base 1 or the clamping portion 2, and the height of the second support block 32 relative to the base 1 is higher than the height of the first support block 31 relative to the base 1, so that the second support block 32 supports under the side of the component 4 to be detected, and further enables the component 4 to be detected fixed in the fixed space to be placed obliquely relative to the base 1. Specifically, the second support block 32 and the clamping portion 2 can move relative to each other along the clamping direction or the loosening direction of the clamping portion 2, so as to adjust the clamping space size of the clamping cavity 21 according to the size and quantity of the component 4 to be detected, etc.; when the second support block 32 is arranged on the base 1, it can mean that the second support block 32 is indirectly arranged on the base 1. Specifically, in actual design, a support rod can be arranged on the base 1, and the second support block 32 can be arranged on the support rod, so as to ensure that the second support block 32 is higher than the first support block 31; of course, it can also be that the base 1 itself has a boss, and the second support block 32 is arranged on the boss.

[0050] In this design method, the obliquely extending component 4 to be detected can be supported by the first support block 31 and the second support block 32 respectively at the bottom and under the side of the component 4 to be detected to maintain the position of the component 4 to be detected. The positioning is accurate and convenient, and the obliquely extending method can enable the detection end 41 of the component 4 to be detected to be far away from the base 1 and the clamping portion 2, further providing sufficient detection space for the component 4 to be detected, and at the same time reducing the space occupation in the vertical direction.

[0051] In some embodiments, the top of the obliquely extending component 4 to be detected extends out of the side of the clamping portion 2, that is, the detection end 41 of the component 4 to be detected extends out of the side of the clamping portion 2, which is convenient for detecting the detection end 41 of the component 4 to be detected by a detection piece.

[0052] In some embodiments, in combination with Figures 1 to 4As shown in the figure, taking the orientation of each component in the figure as the reference standard, the base 1 includes a bottom plate 12 and a surrounding frame 13 arranged on the bottom plate 12. The clamping part 2 is arranged on the surrounding frame 13. The first support block 31 is arranged on the bottom plate 12 and is located on one side or opposite sides of the surrounding frame 13, and the position of the first support block 31 is opposite to that of the clamping cavity 21, so that the part of the component 4 to be detected extending out of the clamping cavity 21 can be supported on the first support block 31. The second support block 32 is arranged on the top of the clamping part 2, and the second support block 32 and the first support block 31 are arranged staggeredly in the vertical direction, that is, the second support block 32 is located at the top of the side of the clamping part 2 away from the first support block 31. The component 4 to be detected extends upward out of the clamping cavity 21, and the bottom of the side of the upward extending part of the component 4 to be detected is supported on the top of the second support block 32.

[0053] In this arrangement, the first support block 31 and the second support block 32 can support the inclined component 4 to be detected, and at the same time make the positioning of the component 4 to be detected stable and accurate.

[0054] In some embodiments, in combination with Figure 1 and Figure 2 As shown, the top surface of the first support block 31 is provided with a first inclined surface 312 and a second inclined surface 313, and an arc-shaped groove 314 is provided between the first inclined surface 312 and the second inclined surface 313. Specifically, the first inclined surface 312 is close to the surrounding frame 13, the second inclined surface 313 is far from the surrounding frame 13, and both the first inclined surface 312 and the second inclined surface 313 are inclined downward along the direction away from the surrounding frame 13. The first inclined surface 312 and the second inclined surface 313 may be parallel or not parallel, and the planes where the first inclined surface 312 and the second inclined surface 313 are located may coincide or not coincide, which can be designed according to actual needs. The arc-shaped groove 314 is opened between the first inclined surface 312 and the second inclined surface 313. Opening the arc-shaped groove 314 can reduce the weight while reserving slots that may be required for subsequent processes such as limiting or positioning.

[0055] In this design, the volume of the first support block 31 can be reduced, the weight of the whole device can be reduced, and the design of the first inclined surface 312 and the second inclined surface 313 makes way for the installation of the component 4 to be detected, increasing the convenience of installing the component 4 to be detected.

[0056] In some embodiments, in combination with Figure 1 、 Figure 2 and Figure 6 , the inner side of the second support block 32 is provided with a third inclined surface 321, which can play a guiding role for the installation of the component 4 to be detected through the third inclined surface 321, increasing the convenience of installing the component 4 to be detected. At the same time, the third inclined surface 321 can also better support the component 4 to be detected.

[0057] In some embodiments, the second support block 32 and the clamping plate 22 can be slidably engaged along the perpendicular direction of the two clamping plates 22 to be able to adapt to the movement of the clamping plate 22 and facilitate adjusting the size of the clamping cavity 21.

[0058] In some embodiments, a chute 221 is formed at the top of the clamping portion 2, and a raised strip 322 is provided on the bottom surface of the second support block 32. The raised strip 322 is adapted to be in the chute 221, and the bottom surface of the second support block 32 supports on the top surface of the clamping portion 2. Figure 1 and Figure 2 As shown in combination with Figure 1 and Figure 2 , corresponding chutes 221 are provided on the two clamping plates 22 along the perpendicular direction of the two clamping plates 22. A raised strip 322 consistent with the above perpendicular direction is provided on the bottom surface of the second support block 32. The raised strip 322 is adapted to be in the chute 221, and the bottom surface of the second support block 32 supports on the top surface of the clamping plate 22.

[0059] In some embodiments, the component 4 to be detected is a soft-pack battery cell, and a receiving groove 311 for receiving the tabs of the battery cell is provided on the first support block 31.

[0060] In this design, the tabs of the battery cell can be received in the receiving groove 311 to avoid damaging the tabs when positioning the battery cell, thereby avoiding affecting the performance of the battery cell.

[0061] In some embodiments, as shown in combination with Figure 3 and Figure 4 , the clamping cavity 21 can accommodate a plurality of components 4 to be detected placed side by side. In actual design, the number of components 4 to be detected placed therein is controlled by adjusting the size of the clamping cavity 21. Figure 3 and Figure 4 In this design, a plurality of components 4 to be detected can be detected simultaneously by one detection fixture, increasing the detection efficiency.

[0062] It can be understood that when the component 4 to be detected is a soft-pack battery cell, there can be a plurality of soft-pack battery cells placed side by side. At this time, there should also be a plurality of receiving grooves 311 arranged side by side to respectively receive the tabs of the plurality of soft-pack battery cells, including the positions where the tabs are connected to the aluminum-plastic film.

[0063] In some embodiments, the clamping portion 2 includes a driving assembly 23 and two spaced clamping plates 22. A clamping cavity 21 is formed between the two clamping plates 22, and the driving assembly 23 can at least drive one of the clamping plates 22 to move along the perpendicular direction of the two clamping plates 22.

[0064]

[0065] ​In this design method, the movement of at least one clamping plate 22 driven by the driving component 23 can change the size of the clamping cavity 21, thereby meeting the clamping requirements of parts 4 to be detected with different sizes and increasing the scope of application. That is, there are two implementation methods for changing the size of the clamping cavity 21 by the driving component 23 at this place. The first implementation method is that the driving component 23 drives the two clamping plates 22 to move synchronously, so that the two clamping plates 22 approach or move away from each other, thereby changing the size of the clamping cavity 21. Another implementation method is that the driving component 23 drives one of the clamping plates 22 to move, so that the clamping plate 22 approaches or moves away from the other clamping plate, thereby changing the size of the clamping cavity 21.

[0066] The following separately describes the two implementation methods for the driving component 23 to change the size of the clamping cavity 21.

[0067] In the first implementation method, the driving component 23 drives the two clamping plates 22 to move synchronously.

[0068] In some implementation methods, as shown in combination with Figure 5 and Figure 7 , the driving component 23 includes two driving plates 231 and a driving rod 232. The two driving plates 231 are respectively arranged on the outer sides of the two clamping plates 22, specifically on the opposite sides of the two clamping plates 22, and the two driving plates 231 are fixedly connected to the two clamping plates 22, so as to be able to drive the clamping plates 22 to move synchronously through the driving plates 231. The driving rod 232 passes through the two driving plates 231, and the driving rod 232 is provided with a first thread and a second thread with opposite thread directions, and the first thread and the second thread are respectively in threaded cooperation with the two driving plates 231.

[0069] Specifically, as shown in Figure 5 , the bottom of the driving plate 231 is provided with an extension plate 2311, the extension plate 2311 extends downward out of the clamping plate 22, and the driving rod 232 is arranged on the extension plate 2311 and is in threaded cooperation with the extension plate 2311, that is, the first thread and the second thread are respectively in threaded cooperation with the two extension plates 2311. The detection fixture is arranged axially symmetrically along the symmetry axis of the two clamping plates 22, so that the weight of the detection component is evenly distributed to ensure the stability of use.

[0070] In this design method, the rotation of the driving rod 232 drives the two extension plates 2311 to approach or move away from each other, and then drives the two clamping plates 22 to approach or move away from each other through the two driving plates 231 to change the size of the clamping cavity 21, which is convenient to operate. At this time, the second support block 32 can be limited to the top of the two clamping plates 22 through other support structures. For example, through a support rod arranged on the base 1, etc. Of course, the second support block 32 can also be limited to the top of the clamping plate 22 through the sliding grooves 221 on the tops of the two clamping plates 22.

[0071] In the second implementation manner, the driving component 23 drives one of the clamping plates 22 to move.

[0072] In some implementation manners, the driving component 23 includes a driving plate 231 and a driving rod 232. A third thread is provided on the driving rod. Specifically, the driving rod can be a screw rod. One of the clamping plates 22 is fixedly arranged on the base 1, and the second support block 32 is fixedly arranged on this clamping plate 22. The other clamping plate 22 is designed to slide along the perpendicular direction of the two clamping plates 22 on the base 1 and is connected to the driving block. The second support block 32 is slidably matched with this clamping plate 22. The driving plate 231 is connected to the driving rod 232. Specifically, the driving plate 231 connected to the slidably arranged clamping plate 22 is connected to the driving rod 232. The driving rod 232 drives the driving plate 231 to drive the clamping plate 22 connected thereto to move towards or away from the other clamping plate 22.

[0073] In this design manner, the clamping plate 22 connected with the second support block 32 is fixedly arranged on the base 1, and the other clamping plate 22 is slidably matched with the second support block 32 to change the size of the clamping cavity 21. The positions of the clamping plate 22 connected with the second support block 32 and the second support block 32 remain unchanged, which can ensure the stability of the positioning of the second support block 32.

[0074] In some implementation manners, the clamping portion 2 further includes a guide plate 241 arranged on the base 1 and a guide groove 242 arranged at the connection of the driving plate 231 and the extension plate 2311. The guide plate 241 passes through the guide groove 242, and the two are slidably matched along the perpendicular direction of the two clamping plates 22 to limit the moving directions of the driving plate 231 and the clamping plate 22.

[0075] The driving manner of the driving rod 232 in this application can be various, specifically as follows:

[0076] In the first driving manner, in some implementation manners, the end of the driving rod 232 extends out of the surrounding frame 13 of the base 1, and a rotating handle is connected to the extending end of the driving rod 232. The staff can drive the driving rod 232 to rotate by operating the rotating handle, and the operation is convenient.

[0077] In the second driving manner: In some implementation manners, the driving component 23 further includes a driving member for driving the driving rod 232 to rotate. By setting the driving member, the driving rod 232 can be driven to rotate automatically, realizing automatic control and saving labor costs.

[0078] It can be seen that the driving manner of the driving rod 232 is not restricted and can be selected according to actual requirements.

[0079] In some implementation manners, such as Figure 7As shown, a bearing seat 11 is provided on the bottom plate 12 of the base 1. A bearing is provided inside the bearing seat 11, and the driving rod 232 is rotationally engaged with the bearing seat 11 through the bearing to increase the smoothness of the rotation of the driving rod 232.

[0080] In some embodiments, as Figure 1 shown, the clamping portion 2 further includes a guide member 24, and at least one clamping plate 22 moves along the perpendicular direction of the two clamping plates 22 under the action of the guide member 24.

[0081] In this design, the guide member 24 can play a guiding role for the movement of the clamping plate 22 to restrict the movement direction of the clamping plate 22, ensuring that the clamping surface of the clamping plate 22 can act on the side surface of the component 4 to be detected and ensuring the clamping effect of the component 4 to be detected.

[0082] In some embodiments, in combination with Figure 1 and Figure 5 shown, the driving assembly 23 includes a driving plate 231. The driving plate 231 is connected to the clamping plate 22 and can drive its movement. The guide member 24 includes a guide plate 241 provided on the base 1 and a guide groove 242 provided on the driving plate 231. The guide plate 241 and the guide groove 242 are slidably engaged along the perpendicular direction of the two clamping plates 22.

[0083] Specifically, the guide plate 241 is provided on the surrounding frame 13 of the base 1, that is, both ends of the guide plate 241 are fixedly connected to the corresponding two sides of the surrounding frame 13 respectively. The guide groove 242 is opened at the connection between the driving plate 231 and the extension plate 2311. The guide plate 241 passes through the guide groove 242 to restrict the movement direction of the driving plate 231 and the clamping plate 22.

[0084] It can be understood that the passing path of the guide plate 241 should not affect the movement of the clamping plate 22 to ensure that the clamping plate 22 can clamp or loosen the component to be clamped.

[0085] Of course, as a variant embodiment of the above guide member, the guide member 24 includes a guide plate 241 provided on the base 1 and a guide strip provided on the driving plate 231. A guide groove is opened at the corresponding position of the guide plate 241 and the guide strip. The guide strip is adaptively installed in the guide groove. At this time, the bottom surface of the driving plate 231 is supported on the guide plate 241, and the driving plate 231 slides along the guide groove on the guide plate 241 in a preset direction.

[0086] In some embodiments, when the first support blocks 31 are arranged on the bottom plate 12 and located on opposite sides of the surrounding frame 13, in other words, the corresponding two sides of the surrounding frame 13 of the base 1 are both provided with the first support blocks 31, and the two first support blocks 31 are designed in the same way.
