Description

Technical Field

[0001] This invention relates to the field of battery module disassembly technology, specifically to a battery module disassembly and display platform. Background Technology

[0002] Battery modules typically consist of multiple groups of cells arranged side-by-side, secured with straps to ensure structural stability during use and transportation. In battery module recycling and vocational training, disassembly is often necessary to separate, test, and demonstrate the internal cells, connectors, and structural components. Current battery module disassembly methods typically involve operators removing the straps one by one based on the cell arrangement, then using a support frame to hold and position the cell assembly.

[0003] However, the above-mentioned battery module disassembly method still has the following drawbacks: After long-term charge-discharge cycles, overcharging, or the generation of gas by internal side reactions, the battery cells will bulge. However, the battery cells are tightly constrained by adjacent battery cells and straps, and the bulge is usually only a few tenths of a millimeter to a few millimeters. Moreover, the bulge is hidden inside the gap between adjacent battery cells, making it difficult for operators to directly detect it from the appearance of the module before disassembly. Because this tiny bulge is hidden by adjacent battery cells and lacks obvious features that can be directly observed, operators cannot make an accurate judgment on the bulging battery cells before disassembly. As a result, the bulging battery cells are easily squeezed during disassembly, which may lead to thermal runaway or even fire, posing a significant safety hazard. Summary of the Invention

[0004] The purpose of this invention is to provide a battery module disassembly and display platform to solve the problem in the prior art that the bulge of the battery cells is small and obscured, making it difficult to detect before disassembly and causing safety hazards during the disassembly process.

[0005] The technical problem to be solved by the present invention can be achieved by the following technical solution: a battery module disassembly and display platform, comprising: a disassembly platform, wherein a placement rack and a driving assembly are installed on the top of the disassembly platform, and a battery cell assembly is disposed on the placement rack; A driving component is provided, with an equidistant component mounted on its output end. Multiple feedback components are mounted on the equidistant component. The equidistant component adjusts the spacing between the multiple feedback components so that they are aligned with the gaps between adjacent cells in the cell assembly. The driving component drives the equidistant component to move the multiple feedback components toward the cell assembly and insert them into the gaps. The feedback components detect whether the cells on both sides of the gap are bulging.

[0006] Preferably, the equidistant component includes an adjustment frame, one end of which is connected to the output end of the drive component. A servo motor is installed on the inner wall of the adjustment frame, and an adjustment rod is installed on the output end of the servo motor. One end of the adjustment rod is rotatably connected to the inner wall of the adjustment frame.

[0007] Preferably, the inner wall of the adjustment frame is equipped with a plurality of slide rods, and a plurality of evenly distributed equidistant blocks are slidably connected to the slide rods.

[0008] Preferably, the outer surface of the adjusting rod is provided with a plurality of adjusting grooves, and the plurality of adjusting grooves are distributed in a spiral shape with different pitches along the axial direction of the adjusting rod.

[0009] Preferably, a limiting ball is installed on the equidistant block, and the limiting ball is slidably connected to the adjustment groove.

[0010] Preferably, the feedback component includes a feedback frame, and a connecting rod is installed at the top of the feedback frame, the top of the connecting rod being connected to the bottom of the equidistant block.

[0011] Preferably, a probe is slidably connected within the feedback frame, and an adjustment bar is rotatably connected to the bottom end of the probe.

[0012] Preferably, a compression cylinder is installed on the inner wall of the feedback frame, a compression spring is installed inside the compression cylinder, and a compression rod is slidably connected inside the compression cylinder. One end of the compression rod is connected to the probe, and a magnetic block is installed around the compression rod. An electromagnet is installed at one end of the compression cylinder.

[0013] Preferably, a sealing cylinder is installed on the inner wall of the feedback frame and at the other end of the extrusion cylinder, a sealing rod is slidably connected inside the sealing cylinder, and a transfer fluid is provided inside the sealing cylinder.

[0014] Preferably, a feedback cylinder is installed at the outer end of the feedback frame, a scale marking strip is embedded around the outer side of the feedback cylinder, the feedback cylinder is connected to the sealing cylinder, and a reset strip is installed on the inner wall of the feedback cylinder, with a marking block installed at one end of the reset strip.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: 1. This invention, by setting a probe driven by a compression spring within the feedback frame and a hydraulic transmission circuit consisting of a sealing cylinder, a sealing rod, a transmission fluid, and a feedback cylinder, transmits the amount of thrust of the probe against the battery cell through the incompressible transmission fluid and converts it into the stroke of the marker block within the feedback cylinder. Furthermore, by using the ratio of the cross-sectional area of ​​the sealing cylinder to the feedback cylinder, this stroke is amplified, thereby converting the minute bulge that is difficult to distinguish with the naked eye into a visible displacement deviation that can be directly read on the scale. This allows for reliable and intuitive identification of battery cell bulges without the need for electronic sensors, fundamentally eliminating the safety hazard of bulges that are difficult to detect before disassembly.

[0016] 2. This invention solves the problems of difficulty in detecting multiple battery cells one by one and difficulty in alignment caused by the change in spacing between battery cells of different specifications. It combines detection efficiency with device versatility.

[0017] 3. This invention connects an adjustable strip to the bottom of the probe via an adjustable damping shaft, allowing the detection area to be pre-adjusted and stably maintained according to the direction of the bulging slope of the battery cell. This improves the contact between the detection surface and the bulging surface from point contact to line contact. Furthermore, the locking and releasing of the probe is controlled by the on / off attraction of the magnetic block by an electromagnet, ensuring that the probe is locked in place during the insertion phase and then released. This solves the problems of difficulty in contacting the tilted bulge and premature triggering of the probe, further improving the accuracy and safety of the detection. Attached Figure Description

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] Example 1 Existing battery modules typically consist of multiple groups of cells arranged side by side, with each cell secured by straps to ensure structural stability during use and transportation.

[0022] However, after long-term charge-discharge cycles, overcharging, or the generation of gas by internal side reactions, bulging may occur inside the battery cell. Because the battery cell is tightly constrained by adjacent cells and straps, the amount of bulging is often only a few tenths of a millimeter to a few millimeters, and the bulging part is mostly hidden inside the gap between adjacent cells, making it difficult for operators to detect from the appearance of the module in time before disassembly.

[0023] If a bulging battery cell is squeezed during disassembly, it can easily cause thermal runaway or even fire, posing a significant safety hazard. Especially in practical training settings in vocational schools or training institutions, multiple students often work together around the same disassembly table, with varying levels of experience. If thermal runaway occurs in a bulging battery cell, the impact will be wider and the consequences more severe.

[0024] Therefore, conducting bulge detection on each of the 12 battery cells before formal disassembly is not only a key prerequisite for ensuring the safety of the disassembly operation, but also a necessary step in practical training to ensure the personal safety of teachers and students and cultivate students' awareness of standardized and safe operation.

[0025] like Figures 1 to 8 In this embodiment, to solve the above problems, a battery module disassembly and display platform is provided. The platform includes a disassembly table 1, with a placement rack 11 mounted on its top. The placement rack 11 supports and positions the cell assembly 12, ensuring the gaps between the cells in the cell assembly 12 face upwards for inspection. A drive assembly 2 is also mounted on the top of the disassembly table 1, and a feedback assembly 4 is mounted on the output end of the drive assembly 2. The feedback assembly 4 includes a feedback frame 41, which serves as the supporting body for the inspection mechanism. A compression cylinder 47 is mounted on the inner wall of the feedback frame 41, and a compression spring is installed inside the compression cylinder 47, slidably connected to a compression rod. One end of the compression rod extends out of the compression cylinder 47 and is connected to a probe 50. The probe 50 is slidably connected within the feedback frame 41 and can slide along the feedback frame 41 towards or away from the cell. An adjustment strip 51 is rotatably connected to the bottom end of the probe 50.

[0026] A magnetic block 48 is installed around the outer periphery of the extrusion rod, and an electromagnet 49 is installed at one end of the extrusion cylinder 47 opposite to the magnetic block 48. A sealing cylinder 45 is installed on the inner wall of the feedback frame 41 and at the other end of the extrusion cylinder 47. A sealing rod 46 is slidably connected inside the sealing cylinder 45. The end of the sealing rod 46 facing the probe 50 is opposite to the probe 50. The sealing cylinder 45 is filled with a transmission fluid.

[0027] A feedback cylinder 44 is installed at the outer end of the feedback frame 41. The feedback cylinder 44 is connected to the sealing cylinder 45 through a pipeline, allowing the transfer fluid in the sealing cylinder 45 to flow into the feedback cylinder 44. A scale marking strip is embedded around the outer periphery of the feedback cylinder 44, and a reset strip 52 is installed on the inner wall of the feedback cylinder 44. An indicator block 53 is installed at one end of the reset strip 52. The indicator block 53 can slide along the axial direction of the feedback cylinder 44 and is displayed on the scale marking strip.

[0028] Working principle of feedback component 4: Before the detection starts, feedback component 4 is in the initial state. At this time, electromagnet 49 is energized, which generates magnetic attraction on the magnetic block 48 on the outer periphery of the extrusion rod, locking the extrusion rod together with the probe 50 connected to it in the retracted initial position. At the same time, the extrusion spring in the extrusion cylinder 47 is compressed and is in an energy storage state.

[0029] On one side of the sealing cylinder 45 and the feedback cylinder 44, the reset bar 52 applies a squeezing force to the marker block 53 toward the sealing cylinder 45. This squeezing force is transmitted through the transmission fluid and pushes the sealing rod 46 to the limit position close to the probe 50. At this time, the transmission fluid in the feedback cylinder 44 is at the initial liquid level, and the marker block 53 stays at the starting position of the scale marker bar.

[0030] When the probe 50 moves down with the drive assembly 2 and inserts into the gap between two adjacent sets of cells, the operator disconnects the power supply to the electromagnet 49. The magnetic block 48 instantly loses its attraction force, the compression spring releases the stored energy, and pushes the compression rod to move the probe 50 and the adjustment bar 51 at its bottom toward the surface of the cell and abut against the side of the cell.

[0031] As the probe 50 moves toward the battery cell, its other movement compresses the sealing rod 46. The sealing rod 46 compresses the transmission fluid in the sealing cylinder 45, causing the transmission fluid to enter the feedback cylinder 44 through the connecting pipe. The transmission fluid entering the feedback cylinder 44 pushes the marker block 53 to overcome the squeezing force of the reset strip 52 and move along the feedback cylinder 44. The final position of the marker block 53 on the scale marker strip accurately reflects the actual distance the probe 50 has advanced.

[0032] It should be emphasized that the core improvement of this embodiment is that, in response to the technical problem that the bulge of the battery cell is small and difficult to detect from the appearance due to being blocked by adjacent battery cells and straps, this embodiment does not directly measure the bulge itself, but instead converts the bulge amount into the amount of the probe 50's advance to indirectly reflect it.

[0033] Since the position of the equidistant block of each feedback component 4 is a preset fixed value before insertion, that is, the probe 50 maintains a preset specific distance from one side of the cell, the surface position of the normal cell is determined, and the amount of advancement when the probe 50 touches the normal cell is also determined.

[0034] When a cell bulges, the bulging surface protrudes outward and gets closer to the center of the gap. The probe 50 is blocked by the bulging surface before it has completed its normal stroke, reducing the amount of propulsion. Consequently, the amount of transmission fluid pressed into the feedback cylinder 44 decreases, and the stroke of the marker block 53 is shortened. Thus, the tiny bulges that are difficult to distinguish with the naked eye are transformed into magnified displacement deviations that can be directly read on the scale, enabling reliable and intuitive identification of the bulges.

[0035] It should be noted that the sealing cylinder 45 and the feedback cylinder 44 have different cross-sectional areas; the sealing cylinder 45 has a larger cross-sectional area, while the feedback cylinder 44 has a smaller cross-sectional area. According to the law of conservation of fluid volume, the volume of fluid displaced by the sealing rod 46 within the sealing cylinder 45 is equal to the volume swept by the marker block 53 within the feedback cylinder 44. In other words, the cross-sectional area of ​​the sealing cylinder multiplied by the amount of advancement of the sealing rod is equal to the cross-sectional area of ​​the feedback cylinder multiplied by the stroke of the marker block.

[0036] Therefore, it can be deduced that the stroke of the marker block 53 is equal to the advance amount of the probe 50 multiplied by the ratio of the cross-sectional area of ​​the sealing cylinder to the cross-sectional area of ​​the feedback cylinder. That is, the larger the cross-sectional area of ​​the sealing cylinder and the smaller the cross-sectional area of ​​the feedback cylinder, the greater the amplification factor of the stroke of the marker block relative to the advance amount of the probe.

[0037] Based on this amplification relationship, even a difference in the advance of probe 50 of only a few tenths of a millimeter can be amplified into a clearly readable stroke difference on the feedback cylinder 44, thereby ensuring the sensitivity to read tiny bulges.

[0038] It should be noted that an incompressible transfer liquid is used as the transfer medium inside the sealing cylinder 45, rather than a compressible gas. The purpose of this is to prevent the displacement of the probe 50 from being absorbed by the compression of the medium itself during the transfer process.

[0039] If gas is used, part of the displacement generated by the advancement of probe 50 will be converted into an increase in gas pressure rather than the movement of marker block 53. The displacement signal corresponding to the tiny bulge is easily submerged by the compressibility of the gas. However, if a transfer fluid is used, the displacement of probe 50 can be converted into the stroke of marker block 53 almost without loss, thus ensuring the accuracy and reliability of tiny bulge detection.

[0040] In this embodiment, the scale marking strip embedded on the outer periphery of the feedback cylinder 44 is pre-marked with the standard range corresponding to a normal battery cell.

[0041] The standard range is calculated based on the preset specific distance between the probe 50 and the battery cell and the volume of the sealing cylinder 45: under the premise that the distance between the probe 50 and the battery cell is fixed, the probe advance amount corresponding to the normal battery cell is determined, thereby calculating the position range that the marker block 53 should reach.

[0042] During testing, the operator only needs to observe whether the marker block 53 falls within the standard range to determine whether the cells on both sides of the gap are bulging. If the marker block 53 does not reach the standard range, it indicates that the transmission fluid entering the feedback cylinder 44 is too little and the probe advance is too small, which means that the corresponding cell is bulging.

[0043] The entire testing process requires no additional electronic sensors or computing equipment; it can be completed solely through mechanical transmission and scale readings, making it simple, intuitive, and reliable.

[0044] More importantly, in practical training scenarios, this testing method transforms the originally hidden and abstract safety hazard of bulging battery cells into a scale displacement that students can directly observe and read. This allows many students watching to clearly judge the battery cell status at a glance. It not only eliminates the risk of thermal runaway caused by bulging battery cells before formal disassembly and effectively protects the personal safety of teachers and students, but also allows students to understand the principle of bulging detection and the importance of safe operation through intuitive operation and reading. This fully demonstrates the practical training significance of this device in integrating education with operation and promoting teaching through safety.

[0045] Example 2 It is understandable that, in Embodiment 1, although the feedback component 4 can detect bulging of cells on both sides of a single gap, in actual battery modules, there are often multiple sets of cells arranged in parallel, and correspondingly, there are multiple gaps that need to be detected.

[0046] If relying solely on a single feedback component 4 to manually shift and inspect each gap, the inspection efficiency is low and the sequential alignment is tedious. Furthermore, different battery module specifications have varying cell thicknesses and spacing between adjacent cells, making it difficult for a single, fixed-position feedback component 4 to automatically adapt to these changes. This can easily lead to misalignment of the probe 50 with the gaps, resulting in the probe pressing against the cell body, thus compromising the universality and consistency of the inspection. Therefore, a mechanism is needed that can simultaneously inspect multiple gaps and automatically adjust the spacing according to the cell specifications.

[0047] like Figures 2 to 5 To solve the above problems, an equidistant component 3 is installed at the output end of the drive component 2. Multiple feedback components 4 are installed on the equidistant component 3, which uniformly supports and adjusts the spacing of each feedback component 4.

[0048] Specifically, the equidistant component 3 includes an adjusting frame 31, one end of which is connected to the output end of the drive component 2, and is driven by the drive component 2 to raise and lower as a whole. A servo motor 32 is installed on the inner wall of the adjusting frame 31, and an adjusting rod 33 is installed on the output end of the servo motor 32. One end of the adjusting rod 33 is rotatably connected to the inner wall of the adjusting frame 31, so that the adjusting rod 33 can rotate smoothly within the adjusting frame 31 under the drive of the servo motor 32. Multiple adjusting grooves 36 are formed on the outer surface of the adjusting rod 33, and the multiple adjusting grooves 36 are distributed in a spiral shape with different pitches along the axial direction of the adjusting rod 33.

[0049] Multiple sliding rods 34 are also installed on the inner wall of the adjusting frame 31. The sliding rods 34 are parallel to the adjusting rod 33. Multiple evenly distributed equidistant blocks 35 are slidably connected to the sliding rods 34. Limiting balls 37 are installed on the equidistant blocks 35, and the limiting balls 37 extend into the corresponding adjusting grooves 36 and are slidably connected to the adjusting grooves 36. A connecting rod 42 is installed at the top of the feedback frame 41 of each feedback component 4. The top of the connecting rod 42 is connected to the bottom of the corresponding equidistant block 35, so that each equidistant block 35 is suspended downward and carries one feedback component 4.

[0050] Working principle of equidistant component 3: After the servo motor 32 starts, it drives the adjusting rod 33 to rotate. When the adjusting rod 33 rotates, the spiral wall of each adjusting groove 36 on its outer surface exerts an axial pushing force on the limiting ball 37 embedded therein, forcing each equidistant block 35 to slide along the slide rod 34 with the limiting ball 37. Since the pitch of each adjusting groove 36 is different, when the adjusting rod 33 rotates by the same angle, the distance that each equidistant block 35 moves along the slide rod 34 is also different. The equidistant block 35 on the outer side has a larger pitch and moves a larger distance, while the equidistant block 35 on the inner side moves a smaller distance. In the end, the multiple equidistant blocks 35 always expand or contract synchronously symmetrically about the center of the adjusting frame 31, and the spacing between them is equal everywhere.

[0051] Multiple feedback components 4 move synchronously with their respective equidistant blocks 35, thereby synchronously increasing or decreasing the spacing between adjacent feedback components 4 to adjust to a spacing corresponding to the gaps between adjacent cells in the cell group 12. After the spacing is adjusted to the correct position, the drive component 2 is activated to move the entire equidistant component 3 and the multiple feedback components 4 below it toward one side of the cell group 12, so that multiple probes 50 are simultaneously inserted into each gap and positioned in the middle of the two groups of cells. Then, as described in Embodiment 1, the bulge detection of the cells on both sides of each gap can be completed synchronously.

[0052] It should be emphasized that the core improvement of this embodiment is: in response to the technical problems of difficulty in inspecting multiple sets of battery cells one by one and difficulty in alignment caused by the change in the spacing of battery cells of different specifications, this embodiment uses an equidistant component 3 to drive an adjusting rod 33 with a spiral groove with different pitches through a single servo motor 32, so that multiple equidistant blocks 35 can be expanded or contracted synchronously and at equal intervals along the slide bar 34, thereby driving multiple feedback components 4 to adjust to the spacing that matches the gap of the battery cells at one time and insert them for inspection at the same time.

[0053] This design ensures that multiple feedback components 4 are evenly and equidistantly distributed at any spacing, making the standard interval calibrated according to a fixed distance in Embodiment 1 equally applicable to each feedback component 4. It also allows the same device to adapt to battery cell groups of different thicknesses and spacings by simply setting the rotation amount of the servo motor 32, which significantly improves the detection efficiency and greatly enhances the versatility of the device.

[0054] It should be noted that when adjusting the spacing for cells of different sizes, the required spacing between adjacent feedback components 4 is the width on both sides of a normal cell plus the preset specific distance between the probe 50 and the cell.

[0055] The operator calculates the target spacing based on the specifications of the battery cell to be inspected, and then sets the rotation amount of the servo motor 32 accordingly. This allows each equidistant block 35 to be precisely positioned, and each probe 50 to fall accurately into the middle of the corresponding gap, maintaining a consistent initial detection distance. This provides consistent initial conditions for subsequent interpretation according to a unified standard.

[0056] It should be noted that each feedback component 4 is suspended below the corresponding equidistant block 35 via the connecting rod 42. The equidistant block 35 can only slide linearly along the slide rod 34 and cannot rotate around the slide rod 34. Therefore, the slide rod 34 serves the dual function of bearing and guiding, and preventing rotation. This constraint ensures that each feedback component 4 maintains a vertical posture throughout the entire process of spacing adjustment, overall downward movement, and insertion of the probe 50 into the gap. The probe 50 will not scrape against the battery cell body due to swaying, ensuring a smooth insertion process and accurate alignment.

[0057] like Figures 4 to 5 In this embodiment, the limiting ball 37 on the equidistant block 35 and the adjusting groove 36 adopt a spherical sliding fit with the groove wall. The limiting ball 37 can slide smoothly along the spiral trajectory of the adjusting groove 36, and can always maintain contact with the groove wall without dislodging when the adjusting rod 33 rotates. This reliably converts the rotation of the adjusting rod 33 into the translation of the equidistant block 35 and eliminates transmission backlash. This fit ensures smooth and jam-free positioning of the equidistant block 35, further guaranteeing the synchronization and accuracy of the spacing adjustment of multiple feedback components 4, and ensuring the comparability of multi-point detection results.

[0058] Example 3 It is understandable that, in Embodiment 2, although the multiple feedback components 4 can be synchronously aligned and inserted into each gap, there are still two problems that need to be solved regarding the actual fit between the probe 50 and the surface of the battery cell.

[0059] Firstly, in most cases, the bulge of the battery cell is not a regular outward protrusion of a flat surface, but rather a bulge with a certain inclination along the surface of the battery cell. If the detection part at the bottom of the probe 50 is at a fixed angle and can only be against the battery cell with a flat end face, it is difficult to fully fit with the inclination bulge. The contact part may only be a point or fall on the edge of the bulge, which cannot truly reflect the maximum amount of bulge, resulting in an underestimation of the detection result or even a missed detection.

[0060] Secondly, the probe 50 tends to be squeezed out towards the battery cell under the continuous pushing force of the compression spring. If the compression spring is released before the probe 50 is fully inserted, the probe 50 will be squeezed out prematurely and come into contact with the battery cell, causing false triggering and incorrect readings. Therefore, further improvements are needed to the fit between the adjustment bar 51 and the battery cell.

[0061] like Figure 6 , Figure 7 To address the aforementioned issues, an adjusting bar 51 is rotatably connected to the bottom of the probe 50 via an adjustable damping shaft. The adjusting bar 51 is the detection part that directly mates with the surface of the battery cell. Simultaneously, an electromagnet 49 is installed at one end of the extrusion cylinder 47, and a magnetic block 48 is installed around the outer periphery of the extrusion rod. The locking and releasing of the probe 50 is controlled by the electromagnet 49 attracting and de-energizing the magnetic block 48. The adjusting bar 51 can rotate relative to the probe 50 to a set angle using the damping shaft, and remains at that angle without deflecting due to the damping of the shaft.

[0062] The working principle of the adjustment bar 51 in conjunction with the battery cell: Before the probe 50 is inserted into the gap, the operator first manually rotates the adjustment bar 51 according to the possible tilt direction of the bulging surface of the battery cell to be inspected, so that the tilt direction of the adjustment bar 51 corresponds to the direction of the bulging diagonal line on the side of the battery cell, and adjusts the adjustment bar 51 to a posture parallel to the diagonal line of the battery cell; at this time, the electromagnet 49 is energized and attracts the magnetic block 48, locking the extrusion rod together with the probe 50 and the adjustment bar 51 in the retracted initial position, so that the extrusion spring is kept compressed and stored, thereby ensuring that the adjustment bar 51 will not be squeezed out in advance or interfere with the battery cell during the process of being inserted into the gap with the drive assembly 2.

[0063] After the adjusting bar 51 is inserted with the drive assembly 2 into the middle position between the two sets of cells, the power supply to the electromagnet 49 is disconnected. The magnetic block 48 loses its attraction, the compression spring is released, and it pushes the compression rod to move the probe bar 50 and the adjusting bar 51 toward the surface of the cell. Since the adjusting bar 51 has been pre-rotated to an angle corresponding to the bulging slope, the adjusting bar 51 can make contact with the inclined bulging surface of the cell along its length, rather than just touching it at a point. This allows it to capture the actual outward convex position on the bulging surface and transmit the most accurate bulge amount to the probe bar 50.

[0064] The probe 50 then presses against the sealing rod 46, which, through the transmission fluid, pushes the marker block 53 to move, ultimately accurately reflecting the degree of bulging of the tilted bulge on the scale of the feedback cylinder 44. When there is a bulge on the surface of the battery cell, regardless of whether the bulge is flat or tilted, its outward protrusion will be transmitted to the probe 50 through the adjusting strip 51 that is in contact with it, and then fed back to the marker block 53, so as to achieve accurate reading of bulges of different shapes.

[0065] It should be emphasized that the core improvement of this embodiment lies in addressing the technical problems of difficulty in detecting tilted bulges and premature triggering of the probe during insertion. This embodiment uses an adjustable damping shaft connected to an adjustment bar 51 at the bottom of the probe 50 to pre-adjust the tilt angle of the detection part according to the direction of the bulging slope of the battery cell and maintain it stably, so that the detection surface and the bulging surface change from point contact to line contact, thereby capturing the true maximum bulge amount. At the same time, through the controllable adsorption of the electromagnet 49 and the magnetic block 48, the probe 50 is locked in the initial position during the insertion stage and released as needed after it is in place, ensuring the accuracy of the detection triggering timing.

[0066] The two work together to avoid false triggering and to ensure that the adjustment strip 51 can fully fit with the battery cell bulges of different shapes and tilt directions, thereby further improving the accuracy and safety of the detection.

[0067] It should be noted that the damping torque of the damping shaft between the adjusting bar 51 and the probe bar 50 is set to be greater than the sum of the torque formed on the shaft by the weight of the adjusting bar 51 itself and the reaction force of the adjusting bar 51 in contact with the battery cell during the detection process. Therefore, the adjusting bar 51 can be stably maintained after being adjusted to the set tilt angle, and will not be squeezed by the surface of the battery cell and deflected by itself during the insertion and squeezing process, thus ensuring the reliability and constancy of the contact angle between the detection surface and the bulging surface.

[0068] It should be noted that the magnetic block 48 is installed around the periphery of the extrusion rod and moves with the extrusion rod. The electromagnet 49 is fixed to the end of the extrusion cylinder 47. The attraction and release between the two can be achieved simply by switching the power supply on and off the electromagnet 49. The control method is simple and reliable. Moreover, after the power is cut off, the thrust of the extrusion spring can immediately act on the probe 50, so that the adjusting bar 51 quickly comes into contact with the battery core. The detection response is rapid, avoiding the impact of the reading due to the release lag.

[0069] In this embodiment, after the test is completed, the electromagnet 49 is energized again. Its attraction to the magnetic block 48 overcomes the pushing force of the compression spring, pulling the compression rod and probe 50 back to their initial retracted positions. The adjusting bar 51 detaches from the battery cell surface along with the probe 50, and the probe 50 simultaneously releases its compression on the sealing rod 46. At this time, the transmission liquid in the sealing cylinder 45 flows back to the sealing cylinder 45 through the connecting pipe under the pressure of the reset bar 52 on the marker block 53. The sealing rod 46 is pushed back to its limit position, and the marker block 53 is reset to the scale position corresponding to the initial liquid level. The entire feedback assembly 4 returns to its initial state ready for the next test, thereby enabling multiple repeated tests on each gap.

[0070] In summary, the bulge magnification and reading scheme provided in Embodiment 1, the multi-gap synchronous alignment and spacing adjustment scheme provided in Embodiment 2, and the fitting and coordination scheme between the adjustment strip 51 and the tilted bulge surface of the battery cell provided in Embodiment 3 can be combined to form a complete battery module disassembly and display platform. On the same device, multi-gap synchronous alignment, micro-bulge magnification and reading, and precise fitting and detection of tilted bulges are realized in sequence, which comprehensively ensures the efficiency, accuracy, and safety of bulge inspection before battery module disassembly.
