Description

Technical Field

[0001] This utility model relates to the technical field of battery testing, and specifically to a positioning fixture for testing soft-pack batteries. Background Technology

[0002] In the production process of pouch batteries, CT flaw detection is a non-destructive testing method that can clearly reveal the internal structure of the battery and effectively detect defects such as electrode wrinkles, breaks, and the incorporation of metal impurities. During CT flaw detection, it is necessary to ensure that the pouch battery is positioned accurately and stably on the rotating platform. Fixtures are usually used for positioning. However, if the fixture is not firmly fixed, the battery may shift or shake during rotation, which will cause changes in the path of X-rays through the battery, resulting in inaccurate data and ultimately affecting the quality of CT image reconstruction. This may lead to misjudgment or missed detection of defects. For example, if the battery is slightly tilted in the fixture, the reconstructed CT image may show shadows or ghost images of deformation in the internal structure of the battery, thus interfering with the judgment of the real defects.

[0003] In existing technologies, conventional clamps typically use two clamping plates to hold the battery in place. This method has the following problems: 1. Clamping the battery with two simple clamping plates under pressure can lead to battery displacement during testing; 2. This clamp can only test one battery at a time. If more than one battery is placed simultaneously, there will be friction between the batteries, and the battery position may shift during rotation, affecting the final test results; 3. The clamp position is usually fixed, making it unsuitable for detectors in different positions; 4. The clamp base is often non-adjustable, resulting in poor compatibility and difficulty in adapting to clamps of different sizes. Utility Model Content

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0034] like Figure 1-5 As shown, a soft-pack battery testing and positioning fixture includes a fixed base 100 and a test fixture 200. The test fixture 200 is detachably mounted on the fixed base 100 and is used to clamp and position the soft-pack battery.

[0035] Specifically, the fixed base 100 includes a first base plate 110 and a positioning seat 120. The first base plate 110 is provided with a first slide rail 111 arranged laterally. The positioning seat 120 is movably mounted on the first slide rail 111 and can be locked onto the first slide rail 111. The positioning seat 120 is provided with a positioning groove of adjustable size. One end of the test fixture 200 is detachably installed in the positioning groove. The test fixture 200 includes a second base plate 210 and multiple pressure plates 220. The second base plate 210 and adjacent pressure plates 220, as well as any two adjacent pressure plates 220, are provided with clamping spaces for clamping soft-pack batteries. Since the pouch batteries can be located in multiple clamping spaces, multiple pressure plates 220 and the second base plate 210 can clamp multiple pouch batteries simultaneously, enabling sequential testing of multiple pouch batteries and improving testing efficiency. Repeated positioning is not required. Furthermore, since the size of the positioning groove on the positioning seat 120 is adjustable, it can be used with different models of test fixtures 200 without needing to change the fixed base 100 according to the model of the test fixture 200, thus improving its applicability. Moreover, the test fixture 200 can be moved on the first slide rail 111 by the positioning seat 120 to adjust the position of the test fixture 200 to be suitable for testing devices in different positions.

[0036] To adjust the size of the positioning slot, the positioning base 120 includes a first support plate 121, a fixed clamping plate 122, and a movable clamping plate 123. The first support plate 121 is slidably mounted on a first slide rail 111, and the top of the first support plate 121 is provided with a second slide rail 121a arranged in the same direction as the first slide rail 111. The fixed clamping plate 122 is fixed to one side of the first support plate 121, and the movable clamping plate 123 is slidably mounted on the second slide rail 121a. In the initial state, the movable clamping plate 123 can be driven away from the fixed clamping plate 122 to enlarge the positioning slot, allowing one end of the test fixture 200 to be smoothly placed into the positioning slot. Then, the movable clamping plate 123 is driven to move closer to the fixed clamping plate 122, cooperating with the fixed clamping plate 122 to clamp the test fixture 200 located in the positioning slot, ensuring the positioning accuracy of the test fixture 200. That is, the size of the positioning slot is adjusted by the displacement of the movable clamping plate 123 on the second slide rail 121a.

[0037] Furthermore, to achieve the driving and positioning of the movable clamping plate 123, the positioning seat 120 also includes a first adjusting screw 124. One end of the first adjusting screw 124 is located on the outside of the movable clamping plate 123 and abuts against the outside of the movable clamping plate 123. The other end of the first adjusting screw 124 passes through the movable clamping plate 123 and is threadedly engaged with the fixed clamping plate 122. When the first adjusting screw 124 is rotated, due to the transmission action of the thread, the first adjusting screw 124 will push or pull the movable clamping plate 123 to move smoothly along the slide rail, thereby changing the position of the movable clamping plate 123. The distance between 23 and the fixed clamping plate 122 can be adjusted in a direction determined by the rotation direction of the first adjusting screw 124. This allows the operator to adjust the size of the positioning slot to the most suitable clamping state according to the actual width of the test fixture 200. Unlike simple pin or gear adjustment, it can achieve "stepless speed change" fine adjustment, ensuring that the test fixture 200 is firmly and evenly clamped, avoiding shaking caused by excessive gap or deformation of the fixture caused by excessive tightness. This precise locking force is the basis for ensuring the stability of the entire test system during rotation.

[0038] Furthermore, in order to support and position the test fixture 200, the fixed clamping plate 122 and the movable clamping plate 123 together form a positioning groove, and the bottom of both the fixed clamping plate 122 and the movable clamping plate 123 are provided with support parts 123a, and the ends of both the fixed clamping plate 122 and the movable clamping plate 123 are provided with limiting parts 123b. After one end of the test fixture 200 is placed in the positioning groove, the support parts 123a of the fixed clamping plate 122 and the movable clamping plate 123 provide support for it, while the two limiting parts 123b limit its sides to prevent the test fixture 200 from leaving the positioning groove from one side.

[0039] To enable the positioning seat 120 to slide lockably on the first slide rail 111, multiple positioning holes 111a are provided on the first slide rail 111. These holes 111a are spaced apart along the length of the first slide rail 111 on one side. The first support plate 121 is slidably connected to the first slide rail 111 via a slider. A telescopic latch 121b is provided on one side of the slider. The telescopic latch 121b can extend into any one of the positioning holes 111a, forming a rigid, mechanical interlock. This interlock is different from a mechanism that relies on friction for locking. Compared to other structures, this rigid locking mechanism offers higher reliability. Under the centrifugal force and vibration generated during the rotation of the CT equipment, this rigid locking effectively prevents any slight slippage of the first support plate 121, ensuring that the center of the test fixture 200 is always aligned with the rotation axis of the CT turntable. In this embodiment, pressing the telescopic locking pin 121b can disengage it from the positioning hole 111a, thereby unlocking the first support plate 121 from the first slide rail 111. After the first support plate 121 moves into place, the telescopic locking pin 121b can be released, and it automatically resets and locks into the corresponding positioning hole 111a.

[0040] In this embodiment, both the first slide rail 111 and the second slide rail 121a are provided in pairs to ensure the stability of the movement of the first support plate 121 and the movable clamping plate 123.

[0041] Furthermore, to provide a restoring force for the telescopic pin 121b, a positioning block 121c and a stress ring 121d are provided inside the slider. The stress ring 121d is sleeved on the positioning block 121c, and an elastic arm 121e is provided on the stress ring 121d. The telescopic pin 121b is fixed to the end of the elastic arm 121e away from the stress ring 121d. The elastic arm acts as a flexible lever. When an external force (such as an operator pressing the pin or sliding the support plate until it aligns with the positioning hole 111a) is applied, the elastic arm 121e will undergo elastic deformation, driving the telescopic pin 121b fixed at its end to retract. After the external force disappears, the elastic arm 121e drives the telescopic pin 121b to automatically return to its original position. The positioning block 121c serves as the mounting base and fulcrum for the stress ring 121d, ensuring the stability of the elastic force transmission. In this embodiment, when the operator pushes the first support plate 121 to slide, aligning the telescopic pin 121b with the positioning hole 111a, the elastic potential energy stored in the elastic arm 121e is released instantaneously, automatically "springing" the pin into the positioning hole 111a to complete the locking. This process requires no additional manual operation, achieving fully automatic locking. At the same time, the telescopic pin 121b produces a clear "click" sound and feel when it enters the positioning hole 111a, providing the operator with clear and unambiguous feedback on successful locking, effectively preventing the risk of testing due to incomplete locking.

[0042] In this embodiment, the test fixture 200 further includes a fixed side plate 230 and a movable side plate 240. The fixed side plate 230 and the movable side plate 240 are arranged opposite to each other. A second base plate 210 is fixed between the fixed side plate 230 and the movable side plate 240. Multiple pressure plates 220 are movably disposed between the fixed side plate 230 and the movable side plate 240. One side of the fixed side plate 230 is fixedly connected to one side of the second base plate 210, and one side of the movable side plate 240 is hinged to the other side of the second base plate 210. The openings of multiple clamping spaces all face the movable side plate 240. The movable side plate 240 has a first position for blocking the openings of the clamping spaces and a second position for opening the openings of the clamping spaces. Through the hinged arrangement of the movable side plate 240 and the second base plate 210, when it is necessary to install... When installing batteries, the movable side plate 240 is driven to the second position, fully exposing the openings of multiple clamping spaces. The operator can easily and naturally insert multiple batteries in sequence, without having to laboriously stuff the batteries into narrow top or side gaps as with traditional clamping fixtures. In this process, since the pouch batteries can be horizontally and stably "placed" on the base plate and pressure plate 220, rather than being "stuffed" or "squeezed" into narrow spaces, the risk of the batteries being bumped, scratched, or deformed during installation is greatly reduced, effectively protecting the safety of the pouch batteries and the accuracy of subsequent tests. When the movable side plate 240 is in the first position, the movable side plate 240 can cooperate with the fixed side plate 230 to block the clamping space, preventing the pouch batteries from falling out of the openings of the clamping space.

[0043] Furthermore, to ensure the movable side panel 240 provides better lateral protection, a magnet is provided on the inner side of the movable side panel 240, and a magnetic suction plate 211 is provided on the second base plate 210. The magnetic suction plate 211 can be attracted to the magnet to keep the movable side panel 240 in the first position. The locking action does not require any tools or complicated rotation operations. The operator only needs to gently close the movable side panel 240, and the magnetic force will automatically pull it tight and hold it in place, achieving a true "one-click" locking. The operation is completed instantly. When unlocking, only a pulling force sufficient to overcome the magnetic force is needed to open the side panel. It will not cause any wear, scratches or mechanical damage to the movable side panel 240, the second base plate 210 or the soft-pack battery. Compared with the method of loosening screws or prying metal buckles, it is safer for the equipment itself and the internal battery, and the operation is more convenient. At the same time, as long as a magnet with sufficient magnetic force is selected, it can be ensured that the movable side panel 240 will not accidentally pop open due to inertia or vibration in the rotational vibration environment of CT testing, and will always be firmly held in the first position, providing a reliable guarantee for the stability of the test.

[0044] Furthermore, to enable the multiple pressure plates 220 to cooperate with the second base plate 210 to clamp multiple soft-pack batteries, the test fixture 200 also includes a second adjusting screw 250 and an adjusting nut 260. Each end of the multiple pressure plates 220 is provided with a through groove 221. One end of the second adjusting screw 250 is connected to the second base plate 210, and the other end can pass through the multiple through grooves 221 and is located outside the pressure plate 220. The adjusting nut 260 is threadedly engaged with the end of the second adjusting screw 250 away from the second base plate 210. Furthermore, the diameter of the adjusting nut 260 is greater than the width of the through slot 221. After the soft-pack battery is placed in the clamping space, the adjusting nut 260 can be rotated. The adjusting nut 260 moves horizontally on the second adjusting screw 250. If the adjusting nut 260 moves towards the side closer to the second base plate 210, it will squeeze the pressure plate 220 away from the second base plate 210 and transmit the force through the soft-pack battery in the middle, so that each pressure plate 220 fits the corresponding soft-pack battery, thereby clamping multiple soft-pack batteries.

[0045] The fixed side plate 230 is provided with a guide groove 231 arranged in the same direction as the second adjusting screw 250. A guide block 223 is provided on one side of the pressure plate 220. The guide block 223 can extend into the guide groove 231. The cooperation between the guide block 223 and the guide groove 231 guides the movement of the pressure plate 220 and prevents it from tilting.

[0046] In this embodiment, anti-slip steps 222 for limiting the movement of the soft-pack battery are provided on the opposing surfaces of the second base plate 210 and the pressure plate 220. The anti-slip steps 222 mainly constrain the movement of the soft-pack battery in the horizontal plane. Combined with the pressure of the fixed side plate 230, the movable side plate 240, and the pressure plate 220, they together form a three-dimensional, all-round limiting system, which improves the positioning accuracy and detection accuracy of the soft-pack battery.
