[0045] Example 1

[0046] This embodiment provides a thickness measuring device for detecting the thickness of a test piece 100, and is particularly suitable for measuring the thickness of a pouch battery with a non-rigid outer surface. In this embodiment, a pouch battery is used as an example for illustration.

[0047] like Figures 1-3 As shown, the thickness measuring device includes a support assembly 10, a drive assembly 20, a connecting assembly 30, a pressing assembly 40, a pressure detection element 50, and a distance measuring assembly. The support assembly 10 has a support surface 121, which is horizontal and supports the lower surface of the workpiece 100 to be measured. The connecting assembly 30 connects the output end of the drive assembly 20 and the pressing assembly 40. The pressing assembly 40 includes a pressing surface 421, which is located above and opposite to the support surface 121. The drive assembly 20 drives the pressing assembly 40 to move up and down via the connecting assembly 30, causing the pressing surface 421 to press against the upper side of the workpiece 100. The pressure detection element 50 is disposed between the connecting assembly 30 and the pressing assembly 40, and is used to detect the pressure exerted on the workpiece 100 in the vertical direction. The distance measuring assembly measures the distance between the support surface 121 and the pressing surface 421.

[0048] In this embodiment of the thickness measuring device, when the driving component 20 drives the pressing component 40 to move downward, the workpiece 100 to be measured can be clamped between the supporting surface 121 and the pressing surface 421, so that the distance measuring component can detect the thickness of the workpiece 100. During the measurement process, the workpiece 100 is clamped by two planes, which can avoid inaccurate measurement results caused by deformation of the workpiece 100 due to local clamping force. By setting the pressure detection component 50, the force on the workpiece 100 during the thickness measurement process can be monitored, which can help ensure that the force on the workpiece 100 is appropriate during the measurement process, thereby avoiding inaccurate measurement results caused by excessive or insufficient force on the workpiece 100. When measuring the thickness of different workpieces 100, it is easy to ensure that the force state of the workpiece 100 is consistent, making the thickness measurement standard of the workpiece 100 more uniform and the measurement results more reliable. In addition, by placing the pressure detection element 50 between the connecting assembly 30 and the pressing assembly 40, it is possible to ensure that the pressure detection element 50 can detect the stress state of the test piece 100 in the vertical direction, and it will not directly contact the test piece 100, thus avoiding damage to the test piece by the pressure detection element 50.

[0049] like Figure 1 and Figure 2As shown, the support assembly 10 includes a base plate 11 and a lower pressure plate 12. The lower pressure plate 12 is mounted on the base plate 11, and its upper surface is the support surface 121. The lower pressure plate 12 can be made of a wear-resistant material to reduce wear during use and ensure the accuracy of thickness measurement results.

[0050] The support assembly 10 also includes a mounting plate 13, a first guide rail 71, and a first slider 72. The mounting plate 13 is connected to the base plate 11 and is set perpendicular to the base plate 11. The first guide rail 71 is fixed on the mounting plate 13 and extends vertically. The first slider 72 is connected to the pressing assembly 40 and slides with the first guide rail 71. The cooperation between the first guide rail 71 and the first slider 72 ensures the accuracy of the lifting trajectory of the pressing assembly 40 and the smoothness of the movement process. Optionally, multiple first guide rails 71 can be provided, and multiple first guide rails 71 are arranged at intervals in the horizontal direction. Each first guide rail 71 is slidably connected to at least one first slider 72, and each first slider 72 is connected to the pressing assembly 40. The arrangement of multiple first guide rails 71 can prevent the pressing surface 421 from tilting during the lifting and lowering process of the pressing assembly 40, thereby ensuring that the pressure on the pressing surface 421 is uniform at various positions on the upper surface of the test piece 100.

[0051] like Figure 1 and Figure 2 As shown, the pressing assembly 40 includes a support member 41 and an upper pressure plate 42. The support member 41 is slidably engaged with the first guide rail 71 via a first slider 72. The upper pressure plate 42 is installed on the lower side of the support member 41, and its lower surface is the pressing surface 421. It is understood that the upper pressure plate 42 can be made of a wear-resistant material to reduce wear during use and ensure the accuracy of thickness measurement results.

[0052] like Figure 1 As shown, the thickness measuring device also includes a positioning element 80, which is disposed on the support surface 121. The positioning element 80 is used to position the workpiece 100 to be measured, thereby ensuring the positioning accuracy of the workpiece 100 and ensuring that the pressing surface 421 is accurately pressed onto the upper surface of the workpiece 100. Optionally, the positioning element 80 can be a stop bar.

[0053] In this embodiment, the positioning element 80 is detachably connected to the support assembly 10. Before starting the thickness measurement, the positioning element 80 can be removed from the support assembly 10, and the drive assembly 20 can be controlled to drive the pressing surface 421 to fit against the support surface 121 to confirm that the current height gauge 60 is in a zero-state, thereby ensuring the reliability of the subsequent measurement results. After completing the zero-state confirmation step, the positioning block can be reinstalled on the support assembly 10. Optionally, the positioning element 80 can be connected to the pressing plate 12 by means of snap-fit, fastener connection, etc., which is not specifically limited here.

[0054] In this embodiment, the drive component 20 is a manually driven structure, meaning that the user can operate the drive component 20 to output a pressing action, thereby causing the pressing component 40 to move up and down. The thickness measuring device also includes a prompting component, which is communicatively connected to the pressure detection element 50 and can issue prompting information. Specifically, when the user operates the drive component 20 to bring the pressing surface 421 into contact with the workpiece 100, the pressure detection element 50 begins to detect the force state of the pressing component 40, thereby obtaining the magnitude of the force on the workpiece 100 in the vertical direction and sending it to the prompting component. When the pressure value reaches a preset range, the prompting component issues a prompting message, thereby reminding the operator to stop operating the drive component 20 to continue outputting the pressing action. At this time, the detection result of the thickness detection component is the thickness of the workpiece 100.

[0055] Optionally, in some embodiments, the prompting component includes a display, which is communicatively connected to the pressure detection element 50. The display can show the detection result of the pressure detection element 50. When the user sees that the pressure detection result shown by the display component has reached a preset range, the user can stop operating the drive component 20. In some embodiments, the pressure detection element 50 includes a sound output element, which is communicatively connected to the pressure detection element 50. When the detection result of the pressure detection element 50 reaches a preset range, the sound output element emits an audible prompt, so that the user can promptly stop operating the drive component 20 to continue outputting the downward pressure action. In some embodiments, the prompting component includes an indicator light, which is communicatively connected to the pressure detection element 50. When the detection result of the pressure detection element 50 reaches a preset range, the indicator light emits an indicator light, so that the user can promptly stop operating the drive component 20 to continue outputting the downward pressure action. Of course, in some embodiments, the prompting component may include any two or three of the display, the sound output element, and the indicator light, and no specific limitation is made here.

[0056] like Figure 2 As shown, the drive assembly 20 includes a bracket 21, a lead screw 22, a handle 23, and a nut 24. The lead screw 22 is rotatably mounted on the bracket 21 and extends vertically. The handle 23 is connected to the lead screw 22 and is used for operation by the user. The nut 24 is threadedly connected to the lead screw 22, and the connecting assembly 30 is connected to the nut 24. When the user operates the handle 23, the lead screw 22 rotates, thereby driving the nut 24 to move up and down. The nut 24 then drives the connecting assembly 30 and the pressing assembly 40 connected to the connecting assembly 30 to move up and down. In this embodiment, the bracket 21 is mounted on the base plate 11. The specific structure of the handle 23 is not limited, as long as it facilitates the rotation of the lead screw 22.

[0057] like Figure 2As shown, in this embodiment, the drive assembly 20 also includes a cover 25, which protects the bracket 21, lead screw 22, nut 24, and other structures. In this embodiment, the cover 25 has an installation notch, through which the connecting assembly 30 extends into the cover 25 and connects with the nut. Preferably, the cover 25 has a scale 251, which corresponds to different positions of the connecting assembly 30 as it moves up and down. These positions indicate the distance between the pressing surface 421 and the supporting surface 121. When operating the drive assembly 20, the user can use the scale 251 to roughly determine whether the pressing surface 421 is about to contact the workpiece 100. When the scale 251 is about to contact the workpiece 100, the user can appropriately slow down the operation speed of the drive assembly 20 to stop the operation promptly upon receiving a signal from the prompt component.

[0058] like Figure 2 As shown, the thickness measuring device also includes a second guide rail 91 and a second slider 92. The second guide rail 91 is mounted on the bracket 21 and extends vertically. The second slider 92 is connected to the connecting assembly 30 and slides in cooperation with the second guide rail 91. The use of the second guide rail 91 and the second slider 92 ensures a more accurate lifting trajectory and smoother lifting process for the connecting assembly 30. In this embodiment, two second guide rails 91 are provided, arranged horizontally. Each second guide rail 91 is slidably connected to a second slider 92, and each second slider 92 is connected to the connecting assembly 30. In other embodiments, the number of second guide rails 91 and second sliders 92 can be flexibly set.

[0059] like Figure 3 and Figure 4 As shown, the connecting assembly 30 is provided with a mounting groove 321, and the pressing assembly 40 also includes a docking member 43. At least a portion of the docking member 43 is inserted into the mounting groove 321 in the horizontal direction. The pressure detection element 50 is disposed between the top of the docking member 43 and the groove wall of the mounting groove 321. When the connecting assembly 30 moves downward under the drive of the driving assembly 20, and the pressing surface 421 of the pressing assembly 40 contacts the upper surface of the test piece 100, the pressure detection element 50 located between the upper part of the docking member 43 and the groove wall of the mounting groove 321 can detect the pressure exerted on the test piece 100 in the vertical direction.

[0060] like Figure 4As shown, the mating member 43 can move vertically within the mounting groove 321, so that the mating member 43 is supported on the lower side wall 3212 of the mounting groove 321, or the pressure detection element contacts the upper side wall 3211 of the mounting groove 321. Specifically, under normal conditions, the pressing assembly 40 is supported on the lower side wall 3212 of the mounting groove 321 under the action of gravity. At this time, the pressure detection element 50 located above the mating member 43 does not contact the upper side wall 3211 of the mounting groove 321, and the pressure detection element 50 does not perform pressure detection. When the driving assembly 20 drives the pressing assembly 40 to move downward to contact the upper surface of the test piece 100, the pressing assembly 40 is difficult to move further downward, while the connecting assembly 30 continues to move downward relative to the mating member 43, so that the upper side wall 3211 of the mounting groove 321 contacts the pressure detection element 50, and pressure detection begins. In other words, by setting the docking part 43 to be able to move vertically within the mounting groove 321, the pressure detection part 50 does not perform pressure detection when the pressing assembly 40 does not press down on the test piece 100, thereby improving the service life of the pressure detection part 50.

[0061] In this embodiment, the pressure detection element 50 is a pressure sensor. For example... Figures 2-3 As shown, the connecting assembly 30 includes a first connecting member 31 and a second connecting member 32. The first connecting member 31 is connected to the second slider 92, and the second connecting member 32 is connected to the first connecting member 31. A mounting groove 321 is formed on the second connecting member 32. Figure 4 As shown, an opening 322 is provided on the lower side wall 3212 of the mounting groove 321. The opening 322 can reduce weight. It is understood that the size of the opening 322 is not limited, as long as the lower side wall 3212 of the mounting groove 321 can support the downward pressing component 40 to move upward.

[0062] like Figure 3 and Figure 4 As shown, the support member 41 and the upper pressure plate 42 of the lower pressure component 40 are both located on one side of the mounting plate 13, and the drive component 20 and the connecting component 30 are both located on the other side of the mounting plate 13. The mounting plate 13 is provided with a clearance hole 131. One end of the docking member 43 is connected to the support member 41, and the other end passes through the clearance hole 131 and is inserted into the mounting groove 321.

[0063] like Figure 2 and Figure 3As shown, in this embodiment, the distance measuring component includes a height gauge 60. The main body 61 of the height gauge 60 is connected to the support component 10, and the probe 62 of the height gauge 60 is connected to the pressing component 40. When the pressing component 40 moves up and down, it causes the probe 62 to move relative to the main body 61, thereby enabling the height gauge 60 to measure the thickness of the workpiece 100. It is understood that the height gauge 60 is an existing dimensional measuring instrument, and its specific working principle will not be described in detail here.

[0064] In this embodiment, the support assembly 10 further includes an extension plate 14. One end of the extension plate 14 is connected to the upper end of the mounting plate 13, and the other end is suspended above the pressing assembly 40. The main body 61 of the height gauge 60 is mounted on the extension plate 14, thereby facilitating the connection between the probe 62 and the pressing assembly 40. It is understood that the probe 62 can be directly connected to the pressing assembly 40, or it can be indirectly connected to the pressing assembly 40 through other components; no specific limitation is made here.

[0065] In other embodiments, the distance measurement component includes a distance sensor and an output component. The distance sensor is used to detect the distance between the support surface 121 and the pressing surface 421. The output component is communicatively connected to the distance sensor and is used to output the detection result of the distance sensor. In some embodiments, the distance sensor can be mounted on the support component 10 and the thickness of the workpiece 100 is obtained by detecting the distance between it and the pressing component 40. In some embodiments, the distance sensor can also be mounted on the pressing component 40 and the thickness of the workpiece 100 is obtained by detecting the distance between it and the support component 10; this is not specifically limited here. Optionally, the output component can be a display that directly displays the thickness data measured by the distance sensor. The output component can also be a sound output component that directly announces the measured thickness data via voice.

[0066] In summary, the process of measuring the thickness of a pouch battery using the thickness measuring device of this embodiment is roughly as follows:

[0067] Step 10: Remove the positioning piece 80 from the lower pressure plate 12;

[0068] Step 20: Operate the drive component 20 to move the pressing component 40 downward until the pressing surface 421 contacts the support surface 121 and the detection result of the pressure detection component 50 reaches the preset range.

[0069] Step 30: Confirm whether the current height gauge 60 value is zero. If yes, proceed to the next step. If no, adjust the height gauge 60. Proceed to the next step when the height gauge 60 value is zero.

[0070] Step 40: Operate the drive component 20 to make the pressing component 40 move upward;

[0071] Step 50: Install the positioning element 80 onto the support assembly 10;

[0072] Step 60: Place the soft-pack battery on the support surface 121 and abut against the positioning member 80;

[0073] Step 70: Operate the drive component 20 to move the pressing component 40 downward, so that the pressing surface 421 contacts the upper surface of the test piece 100, and the detection result of the pressure detection component 50 reaches the preset range.

[0074] Step 80: Obtain measurement values ​​from the thickness detection component.

[0075] Understandably, when it is necessary to measure the thickness of multiple pouch cells at once, steps 10-30 can be performed once, and steps 40-80 can be repeated.

[0076] Example 2

[0077] This embodiment provides a thickness measuring device, whose general structure is the same as that of the thickness measuring device in Embodiment 1, except for the structure of the driving component 20, as detailed below:

[0078] The drive assembly 20 includes a drive source, a connecting assembly 30 connected to the output of the drive source, and the drive source drives the pressing assembly 40 to move up and down. A pressure detection element 50 is communicatively connected to the drive source. Specifically, when the pressure detection element 50 detects that the pressure on the test piece 100 in the vertical direction reaches a preset range, it sends a signal to the drive source. Upon receiving the signal, the drive source stops driving the pressing assembly 40. In some embodiments, the drive source is a cylinder; in other embodiments, the drive source is a motor. The motor is connected to the connecting assembly 30 via a transmission structure and drives the connecting assembly 30 to move up and down.

[0079] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model.
