Description

Technical Field

[0001] This invention relates to the field of battery accessory manufacturing technology, and in particular to a size measuring device and method for non-standard battery cases. Background Technology

[0002] To assess whether the machining accuracy and structure meet the cell installation requirements, it is necessary to measure the separators of non-standard battery slots. As the isolation and support structure between cells, the size and position of the separators directly affect the cell arrangement stability, thermal management effect, and overall battery pack performance. If the separators have dimensional deviations, deformation, or misalignment, it may lead to uneven stress on the cells, assembly difficulties, and even safety hazards. Measurement allows for timely detection of problems, guiding design or process corrections to ensure product quality and reliability.

[0003] In existing technologies, when measuring non-standard battery compartment partitions, a clamp is generally used to simply fix the non-standard battery compartment partitions. However, when measuring their length using measuring tools, due to problems such as bending, warping, and deformation caused by processing, transportation, or use, directly measuring the dimensions in the deformed state will result in values ​​such as the width, depth, and angle being too large or too small, leading to distorted measurement data that cannot reflect the actual design dimensions. This can cause problems such as interference or excessive gaps in component assembly. Summary of the Invention

[0004] The purpose of this invention is to address the problem that in the prior art, when measuring non-standard battery compartment partitions, the partitions are generally simply fixed with clamps. However, when measuring their length with measuring tools, problems such as bending, warping, and deformation that occur during processing, transportation, or use make it difficult to directly measure the dimensions in the deformed state. This results in distorted measurement data, which cannot reflect the actual design dimensions and causes problems such as interference or excessive gaps in component assembly.

[0018] Optionally, a main controller is fixedly mounted on the side of one of the vertical seats, and a laser ranging sensor is fixedly mounted on the bottom of the vertical moving seat. The vertical motor, the laser ranging sensor, and the main controller are electrically connected.

[0019] A method for measuring the dimensions of a non-standard battery compartment includes the following steps:

[0020] S1, tensioning and fixing of non-standard battery compartment: the common drive component controls the two tensioning components to fix the two ends of the non-standard battery compartment partition by controlling the force-saving drive component.

[0021] S2, non-standard battery compartment size measurement, the distance between the bottom of the vertical moving seat and the top of the base is obtained by the laser rangefinder at the bottom of the vertical moving seat. Since the height of the vertical seat is fixed and known, the length of the non-standard battery compartment partition between the two tensioning components is obtained.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1. This dimensional measuring device has two tensioning components on the side of the vertical base. The tensioning components first clamp and fix the two ends of the non-standard battery slot partition, and then tighten the non-standard battery slot partition to eliminate measurement errors caused by bending or twisting. Then, a laser rangefinder sensor is used to achieve fast and accurate measurement, ensuring that the obtained dimensions are closer to the design values. The structure has high measurement efficiency, is easy to operate, and can improve measurement accuracy and repeatability. It helps to detect processing deviations in a timely manner and ensures the matching of battery cell installation and the assembly quality of battery pack.

[0024] 2. The tensioning components of this dimensional measuring device have certain characteristics. When clamping the non-standard battery compartment partition, the two tensioning components will move closer to each other and make a slight displacement. This allows the two ends of the non-standard battery compartment partition to fit against the horizontal section of the vertical fold plate in the tensioning component before clamping. This ensures more accurate partition positioning and more stable clamping, effectively preventing the partition from shifting or sliding at the moment of clamping. It improves the consistency of the straightening effect and the reliability of the measurement benchmark, thereby enhancing the accuracy of dimensional measurement, reducing errors, adapting to the diversity of non-standard battery compartment structures, and improving the controllability and repeatability of the measurement process.

[0025] 2. This measuring device features a force-saving drive component and a common drive component on the sides of the two tensioning components. First, the distance between the two tensioning components of this dimensional testing device is adjustable, allowing the device to measure non-standard battery compartment separators of different sizes. Second, the common drive component can control the two tensioning components through the force-saving drive component. The force-saving drive component utilizes the lever principle, allowing the common drive component to generate only a small torque. This, in conjunction with the force-saving drive component, controls the tensioning components. The force-saving drive component, through the lever principle and the common drive component, significantly reduces the torque required for driving, improving driving efficiency and control accuracy. This not only reduces the load on the common drive component and extends its service life, but also achieves a large clamping force with a small input force, ensuring a reliable and uniform tensioning process. Simultaneously, it reduces energy consumption, facilitating automated control and improving the overall performance and reliability of the measuring device.

[0026] 3. The two tensioning components of this measuring device are controlled by the same common drive component. Regardless of whether the two tensioning components are close to or far from each other, the common drive component can simultaneously control the two tensioning components to clamp the two ends of the non-standard battery compartment separator synchronously. The fact that the two tensioning components of this measuring device are uniformly controlled by the same common drive component ensures that the two ends of the separator are subjected to force and uniformly tightened at the same time. This effectively avoids the separator offset, deformation, or uneven force caused by clamping one side first, improves the consistency of the straightening effect, simplifies the drive structure, reduces the complexity of the control system, improves the stability of operation and measurement repeatability, adapts to the measurement needs of battery compartments of different specifications, and enhances the versatility and reliability of the device.

[0042] Reference Figure 1-12 A size measuring device for non-standard battery compartments includes a base 4, a vertical shifter 3, a main controller 6, and a laser rangefinder 10. A back folding plate 7 is symmetrically fixed on the top of the base 4. A vertical seat 2 is provided on the front side of the back folding plate 7. The vertical seat 2 is movably inserted into the vertical shifter 3 along the vertical direction. The vertical seat 2 restricts the vertical movement of the vertical shifter 3. A vertical motor 1 is fixedly installed on the top of the horizontal section of the back folding plate 7. A vertical screw 9 is fixedly installed at the output end of the vertical motor 1. The vertical shifter 3 is screwed into the outer wall of the vertical screw 9. A telescopic baffle 5 is fixedly installed on the inner side of the vertical seat 2.

A sliding cavity is provided through the top of the vertical seat 2 to accommodate the end of the vertical shifter 3. The telescopic baffle 5 can ensure the continuous cleanliness of the sliding cavity of the vertical shifter 3 to a certain extent.

[0043] One of the vertical bases 2 has a main controller 6 fixedly mounted on its side, and a laser rangefinder 10 fixedly mounted on the bottom of the vertical moving base 3. The vertical motor 1, the laser rangefinder 10 and the main controller 6 are electrically connected. The main controller 6 is model S7-1200, and the laser rangefinder 10 is model IL-100. The detection lens of the laser rangefinder 10 is vertically downward and points to the top surface of the base 4.

[0044] The back folding plate 7 includes a vertical section and a horizontal section. The top of the vertical shifter 3 and the bottom of the horizontal section of the back folding plate 7 are both provided with tensioning components. The two tensioning components tighten the two ends of the non-standard battery slot. The tensioning components include a connector 15, a clamping block 16, and a vertical folding plate 17. A horizontal groove 171 is opened on the side of the vertical folding plate 17. A rectangular block 21 is movably inserted into the horizontal groove 171. A clamping block 16 is fixedly provided at the other end of the rectangular block 21. Therefore, the two clamping blocks 16 can move along the connector 15. A force-saving drive component is provided on the opposite side of the two clamping blocks 16. The force-saving drive component drives the clamping blocks 16 inside the connector 15 to move closer or further away from each other while moving vertically. A rectangular cavity 151 is opened on the side of the connector 15, and two clamping blocks 16 are provided.

[0045] An electric push rod 8 is fixedly installed on the side of the back panel 7. A common drive component is installed at the output end of the electric push rod 8. The common drive component simultaneously controls two force-saving drive components when the two tensioning components approach or move away from each other. The force-saving drive component includes a common column 18, a driven column 19, a rear plate 22, and a pressure lever 28. A fixed cylinder 13 is fixedly installed at the bottom of the horizontal section of the back panel 7 and at the top of the vertical shift seat 3. A tension sensor 14 is fixedly installed at the bottom of the fixed cylinder 13. A connector 15 is fixedly installed at the output end of the tension sensor 14. The tension sensor 14 is model HBM-U9C. The tension sensor 14 is used to directly sense the tension on the connector 15 and indirectly sense the tension on the non-standard battery compartment partition when the two connectors 15 tighten it, thus preventing the non-standard battery compartment partition from being overstretched and broken.

[0046] A rear plate 22 is fixedly installed on one side of the connector 15. A driven column 19 is fixedly installed on one end of the rectangular block 21. A horizontal column 20 is inserted into the common side of the two rectangular blocks 21. The horizontal column 20 is movably inserted into the horizontal groove 171. The vertical folding plate 17 includes a horizontal section and a vertical section. A common column 18 is fixedly installed at the middle position of the side of the vertical folding plate 17.

A pressure lever 28 is rotatably connected to the side of the rear plate 22. A loop groove 281 is opened on the side of the pressure lever 28. The common column 18 passes through the loop groove 281. When the end of the pressure lever 28 away from its axis of rotation is subjected to pressure, the pressure lever 28 will apply a large pressure to the common column 18 due to the lever principle.

[0047] The common drive assembly includes a horizontal U-frame 11, a common vertical rod 12, a traction column 25, and a reversing drive assembly. Horizontal columns 121 are fixedly installed at both ends of the common vertical rod 12. The horizontal columns 121 are movably inserted into the side of the rear folding plate 7. The output end of the electric push rod 8 is fixedly installed with the horizontal U-frame 11. The common vertical rod 12 is fixedly installed on the side of the horizontal U-frame 11 away from the output end of the electric push rod 8. A vertical shift groove 120 is opened on the side of the common vertical rod 12. One end of the traction column 25 is movably inserted into the vertical shift groove 120. Guide blocks 251 are fixedly installed on both sides of the traction column 25 and the vertical shift groove 120. The setting of the vertical shift groove 120 and the guide blocks 251 allows the electric push rod 8 to always control the traction column 25 through the common vertical rod 12 and other structures when the two connectors 15 move arbitrarily in the vertical direction.

[0048] The horizontal U-frame 11 has a vertical anti-collision groove 110. The width of the anti-collision groove 110 in the top view is greater than the width of the guide block 251 in the top view, so as to avoid the two sets of guide blocks 251 from colliding with the horizontal U-frame 11 when they move in the vertical direction.

[0049] The reversing drive assembly includes an edge gear ring 27, an intermediate gear 24, a second bevel gear 26, a first bevel gear 241, an end gear 30, and an end rack 32. An edge gear ring 27 is fixedly installed at the end of the pressure lever 28. An intermediate gear 24 is rotatably connected to one side of the edge gear ring 27 on the rear plate 22. The intermediate gear 24 is stably meshed with the edge gear ring 27. A first bevel gear 241 is fixedly installed on the side of the intermediate gear 24. A second bevel gear 26 is stably meshed on the side of the first bevel gear 241. An edge box 23 is fixedly installed on the side of the intermediate gear 24 on the rear plate 22. An clearance groove 231 is opened on the top of the edge box 23 along the vertical direction. The clearance groove 231 provides sufficient space for the rotational movement of the pressure lever 28 and the edge gear ring 27.

[0050] A partition plate 232 is fixedly installed inside the edge box 23. A second bevel gear 26 is rotatably connected to the side of the partition plate 232. A common shaft 29 is fixedly installed on the side of the second bevel gear 26. An end gear 30 is fixedly installed at the other end of the common shaft 29. An end rack 32 is stably meshed at the top of the end gear 30. The end rack 32 is movably inserted into the side of the edge box 23. A T-slot 31 is opened at the corresponding position in the edge box 23. The end rack 32 is fixedly connected to one end of the traction column 25.

[0051] The specific implementation steps and principles of this invention are as follows:

[0052] When the entire device is in standby mode, the common column 18 is at the extreme position at one end of the central vertical groove 220, and the driven column 19 is at the extreme position at one end of the two inclined grooves 221. At this time, the two clamping blocks 16 located in the rectangular cavity 151 of the same connector 15 are at their farthest distance. The vertical motor 1 is pre-started, and the vertical motor 1 drives the vertical moving seat 3 to approach the top of the back folding plate 7 at an appropriate distance. After the worker inserts the two ends of the non-standard battery slot partition into the rectangular cavity 151 on the side of the two connectors 15, the electric push rod 8 is started. The electric push rod 8 retracts and passes through the common vertical column. 12. The pulling column 25 and the guide block 251 drive the end gear 32 to rotate. The end gear 32 drives the pressure lever 28 through the end gear 30, the second bevel gear 26, the intermediate gear 24, and the edge gear ring 27. The pressure lever 28 forces the common column 18 to move along the central vertical groove 220 through the return groove 281. All structures on the vertical folding plate 17 will make slight movements in the vertical direction. The driven column 19 set on the side of the vertical folding plate 17 will move along the inclined groove 221. The two clamping blocks 16 move closer to each other and finally clamp the two ends of the non-standard battery slot partition.

[0053] Specifically, the two clamping blocks 16 located at the top of the rear folding plate 7 will move downwards before clamping, and the two clamping blocks 16 located at the top of the vertical shifting seat 3 will move upwards before clamping. Therefore, the two ends of the non-standard battery slot partition will contact and adhere to the horizontal section of the vertical folding plate 17 before clamping.

[0054] Then, the vertical motor 1 is started, and the vertical moving seat 3 is moved down by the vertical screw 9 until the value of the tension sensor 14 reaches the preset value. Then, the main controller 6 controls the vertical motor 1 to stop. At this time, the main controller 6 obtains the distance between the top of the vertical moving seat 3 and the bottom of the back folding plate 7 through the laser range sensor 10. Since the vertical length of the two connectors 15 is determined, the length of the non-standard battery slot partition is obtained by the main controller 6 through the preset formula.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
