A thickness gauge

Abstract

The application provides a thickness gauge, and relates to the technical field of batteries. In the thickness gauge, when the detector slides between a measurement station where the pole piece is located and a calibration station where the standard piece is located, the first power device drives the lifting plate to slide along a third direction relative to the fixed seat, drives the lifting rod to slide along the third direction relative to the first sliding piece, and drives the second sliding piece and the detector to slide along the third direction relative to the fixed seat under the driving of the lifting rod, so that the detector is lifted in height when being in the calibration station to avoid the standard piece, and the detector is lowered in height when being in the measurement station to return to the original position, thereby helping to reduce the risk of interference between the detector and the standard piece, and further helping to improve the measurement accuracy of the thickness gauge.

Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a thickness gauge. Background Technology

[0002] The information disclosed in this background section is intended only to enhance the understanding of the general background of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0003] Thickness gauges are used to measure the thickness of electrodes in the coating process. In a thickness gauge, if the distance between the detector and the electrode is too large, it can easily increase the measurement error. Therefore, reducing the distance between the detector and the electrode can help reduce the measurement error. However, when the detector slides from the measurement station where the electrode is located to the calibration station where the standard sheet is located, the detector is prone to interference with the standard sheet, which is detrimental to the measurement accuracy of the thickness gauge. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a thickness gauge that aims to solve the technical problem of how to improve the measurement accuracy of the thickness gauge.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows: This application provides a thickness gauge having three mutually perpendicular directions: a first direction, a second direction, and a third direction. The thickness gauge includes: a fixed base; a standard piece fixedly connected to the fixed base; a first sliding member slidably connected to the fixed base along the first direction; a second sliding member slidably connected to the first sliding member along the third direction; a lifting rod passing through the fixed base along the second direction, the lifting rod being movably connected to the fixed base and fixedly connected to the second sliding member, and the lifting rod being slidably connected to the first sliding member along the third direction; a detector fixedly connected to the second sliding member, the detector and the standard piece being arranged at intervals along the first direction; a lifting plate slidably connected to the fixed base along the third direction, the lifting rod being disposed on the side of the lifting plate facing away from the detector along the third direction; and a first power device disposed on the fixed base and connected to the lifting plate.

[0006] In some embodiments, the first power unit includes a cam and a rotating shaft. The cam is located on the side of the lifting plate facing the detector along the third direction, and the rotating shaft passes through the fixed base along the second direction. The rotating shaft is rotatably connected to the fixed base and fixedly connected to the cam.

[0007] In some embodiments, the first power device further includes a first transmission wheel, a second transmission wheel, and a first transmission belt. The first transmission wheel is fixedly connected to the rotating shaft, and the second transmission wheel is rotatably connected to the fixed base. The first transmission wheel and the second transmission wheel are arranged at intervals along the first direction, and the first transmission belt is respectively sleeved on the first transmission wheel and the second transmission wheel.

[0008] In some embodiments, the number of cams, the number of rotating shafts, and the number of first transmission wheels are all multiple. The multiple cams are arranged at intervals along the first direction, and the first transmission belt is respectively sleeved on the multiple first transmission wheels. Among the multiple cams arranged at intervals along the first direction, one cam corresponds to one rotating shaft and one first transmission wheel.

[0009] In some embodiments, the first power unit further includes a first driver, a first bevel gear, and a second bevel gear. The first bevel gear is coaxially arranged with the second transmission wheel and fixedly connected to the second transmission wheel. The second bevel gear meshes with the first bevel gear. The first driver is disposed on the fixed base and is indirectly or directly connected to the second bevel gear.

[0010] In some embodiments, the first power device further includes a third transmission wheel, a fourth transmission wheel, and a second transmission belt. The third transmission wheel and the fourth transmission wheel are rotatably connected to the fixed base. The third transmission wheel is coaxially arranged with the second bevel gear and fixedly connected to the second bevel gear. The first driver is connected to the fourth transmission wheel. The third transmission wheel and the fourth transmission wheel are arranged at intervals along the first direction. The second transmission belt is respectively sleeved on the third transmission wheel and the fourth transmission wheel.

[0011] In some embodiments, the first slider has a through-hole extending along the third direction, the second slider has a connecting hole communicating with the through-hole, and the lifting rod passes through the through-hole and the connecting hole respectively.

[0012] In some embodiments, the first slider is provided with a groove communicating with the sliding hole, the groove being disposed toward the detector in the third direction and extending in the third direction, and the portion of the second slider having the connecting hole is located within the groove.

[0013] In some embodiments, the groove extends through the first sliding member along the first direction, and the thickness gauge further includes a limiting sleeve plate, which is respectively arranged around the first sliding member and the second sliding member. The limiting sleeve plate is fixedly connected to the first sliding member or the second sliding member, and the limiting sleeve plate covers both ends of the groove along the first direction.

[0014] In some embodiments, the fixing base is provided with a first guide groove, a second guide groove and a third guide groove. The second guide groove is connected to the first guide groove and the third guide groove respectively. The first guide groove and the third guide groove both extend along the first direction. The second guide groove extends along the third direction. The third guide groove is positioned close to the standard piece along the first direction relative to the first guide groove. The lifting rod passes through one of the first guide groove, the second guide groove and the third guide groove along the second direction.

[0015] In some embodiments, the fixed base is provided with a lifting groove extending along the third direction, the lifting groove communicating with the first guide groove, the second guide groove and the third guide groove respectively, and the lifting plate is located in the lifting groove.

[0016] The beneficial effects of this application are as follows: In the thickness gauge provided in this application, a first sliding member is slidably connected to a fixed base along a first direction, a second sliding member is slidably connected to the first sliding member along a third direction, a lifting rod passes through the fixed base along a second direction, the lifting rod is movably connected to the fixed base and fixedly connected to the second sliding member, the lifting rod is slidably connected to the first sliding member along a third direction, a detector is fixedly connected to the second sliding member, a lifting plate is slidably connected to the fixed base along a third direction, the lifting rod is located on the side of the lifting plate facing away from the detector along a third direction, and a first power device is located on the fixed base and connected to the lifting plate. Thus, when the detector slides between the measurement station where the electrode is located and the calibration station where the standard piece is located, the first power device drives the lifting plate to slide relative to the fixed base along a third direction, thereby causing the lifting rod to slide relative to the first sliding member along a third direction. This allows the second sliding member and the detector to slide relative to the fixed base along a third direction under the action of the lifting rod. This achieves the following: when the detector is in the calibration station, its height increases to avoid the standard piece; and when it is in the measurement station, its height decreases to return to its original position. This helps reduce the risk of interference between the detector and the standard piece, thereby improving the measurement accuracy of the thickness gauge. Attached Figure Description

Detailed Implementation

[0020] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0021] In the description of this application, the terms "center", "longitudinal", "lateral", "length", "width", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0022] Furthermore, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that they are in indirect contact through an intermediate medium. Moreover, "above" or "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below" or "below" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0023] In the description of this application, the terms "first," "second," etc., are used to distinguish different objects and should not be construed as indicating or implying a specific order or hierarchy, or implicitly specifying the number of technical features indicated. Therefore, a feature marked "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, the term "multiple" means two or more, unless otherwise explicitly defined.

[0024] In the description of this application, unless otherwise explicitly specified, the term "connection" should be interpreted broadly. For example, it can refer to a non-detachable connection, a detachable connection, or a single-piece structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0025] In the description of this application, the term "and / or" can be understood to mean three possibilities. For example, A and / or B can represent: A alone; A and B simultaneously; and B alone. Additionally, the character " / " generally indicates an "or" relationship between the preceding and following objects.

[0026] In the description of this application, "parallel" includes not only the case of absolute parallelism, but also the case of approximate parallelism as commonly understood in engineering; similarly, "perpendicular" also includes not only the case of absolute perpendicularity, but also the case of approximate perpendicularity as commonly understood in engineering. For example, if the angle between two directions is 80° to 90°, the two directions can be considered perpendicular; if the angle between two directions is 0° to 10°, the two directions can be considered parallel.

[0027] In the description of this application, the term "fixed connection" refers to two objects that are connected to each other and whose relative positions remain unchanged under normal use conditions, i.e., they will not easily undergo relative movement (e.g., relative rotation and relative sliding); the term "rotational connection" refers to two objects that are connected to each other and can rotate relative to each other; and the term "sliding connection" refers to two objects that are connected to each other and can slide relative to each other.

[0028] Thickness gauges are used to measure the thickness of electrodes in the coating process. In a thickness gauge, if the distance between the detector and the electrode is too large, it can easily lead to increased interference from ambient light and attenuation of the transmitted signal, thereby increasing the measurement error. Therefore, reducing the distance between the detector and the electrode can help improve the above situation and reduce the measurement error. However, when the detector slides from the measurement station where the electrode is located to the calibration station where the standard sheet is located, the detector is prone to interference with the standard sheet, which is detrimental to the measurement accuracy of the thickness gauge.

[0029] like Figure 1 As shown, in order to solve the above-mentioned technical problems, the embodiments of this application provide a thickness gauge 10, which relates to the field of battery technology and is mainly used to measure the thickness of electrode sheets.

[0030] It should be noted that electrodes are used in battery cells. Battery cells primarily function by the sliding of metal ions between the positive and negative electrodes. Battery cells can be cuboid, cylindrical, flat, or other shapes. Classified by packaging method, battery cells can be prismatic, cylindrical, pouch, etc.; classified by metal ion type, battery cells can be lithium-ion, sodium-ion, etc.; classified by electrolyte physical state, battery cells can be liquid batteries, i.e., using liquid electrolytes (electrolytes); of course, battery cells can also be solid-state or semi-solid-state batteries, i.e., the electrolyte is at least partially solid-state. Common materials include sulfide, oxide, or polymer electrolytes. Solid-state electrolytes can replace separators and liquid electrolytes, combining ion conduction and isolation functions. No specific limitations are made on the type of battery cell here.

[0031] like Figure 1 and Figure 2 As shown, the thickness gauge 10 provided in this embodiment has a first direction X, a second direction Y and a third direction Z that are perpendicular to each other. The thickness gauge 10 includes: a fixed base 100 (the part of the structure of the fixed base 100 is shown in the figure), a standard piece 210, a first sliding member 300, a second sliding member 400, a lifting rod 220, a detector 230, a lifting plate 240 and a first power device 500.

[0032] The standard plate 210 is fixedly connected to the fixed base 100; the first sliding member 300 is slidably connected to the fixed base 100 along the first direction X; the second sliding member 400 is slidably connected to the first sliding member 300 along the third direction Z; the lifting rod 220 passes through the fixed base 100 along the second direction Y, the lifting rod 220 is movably connected to the fixed base 100 and fixedly connected to the second sliding member 400, and the lifting rod 220 is slidably connected to the first sliding member 300 along the third direction Z; the detector 230 is fixedly connected to the second sliding member 400, and the detector 230 and the standard plate 210 are arranged at intervals along the first direction X; the lifting plate 240 is slidably connected to the fixed base 100 along the third direction Z, and the lifting rod 220 is located on the side of the lifting plate 240 facing away from the detector 230 along the third direction Z; the first power device 500 is located on the fixed base 100 and connected to the lifting plate 240.

[0033] It is understood that in the battery cell provided in this embodiment, the first sliding member 300 is slidably connected to the fixed base 100 along the first direction X, the second sliding member 400 is slidably connected to the first sliding member 300 along the third direction Z, the lifting rod 220 passes through the fixed base 100 along the second direction Y, the lifting rod 220 is movably connected to the fixed base 100 and fixedly connected to the second sliding member 400, the lifting rod 220 is slidably connected to the first sliding member 300 along the third direction Z, the detector 230 is fixedly connected to the second sliding member 400, the lifting plate 240 is slidably connected to the fixed base 100 along the third direction Z, the lifting rod 220 is located on the side of the lifting plate 240 facing away from the detector 230 along the third direction Z, and the first power device 500 is located on the fixed base 100 and connected to the lifting plate 240.

[0034] In this way, when the detector 230 slides between the measurement station where the electrode is located and the calibration station where the standard piece 210 is located, the first power device 500 drives the lifting plate 240 to slide relative to the fixed base 100 along the third direction Z, so as to drive the lifting rod 220 to slide relative to the first sliding member 300 along the third direction Z. This allows the second sliding member 400 and the detector 230 to slide relative to the fixed base 100 along the third direction Z under the drive of the lifting rod 220. This enables the detector 230 to rise in height when it is in the calibration station to avoid the standard piece 210 and to fall in height when it is in the measurement station to return to its original position. This helps to reduce the risk of interference between the detector 230 and the standard piece 210, and thus helps to improve the measurement accuracy of the thickness gauge 10.

[0035] like Figures 1 to 3 As shown, in some embodiments, the first power unit 500 includes a cam 511 and a rotating shaft 512. The cam 511 is located on the side of the lifting plate 240 facing the detector 230 along the third direction Z. The rotating shaft 512 passes through the fixed seat 100 along the second direction Y. The rotating shaft 512 is rotatably connected to the fixed seat 100 and fixedly connected to the cam 511.

[0036] In this way, when the rotating shaft 512 drives the cam 511 to rotate, the cam 511 can drive the lifting plate 240 to slide relative to the fixed seat 100 along the third direction Z, thereby enabling the detector 230 to rise in height to avoid the standard piece 210 when it is in the calibration position, and to lower in height to return to its original position when it is in the measurement position.

[0037] like Figure 1 , Figure 6 and Figure 7 As shown, the first power device 500 further includes a first transmission wheel 521, a second transmission wheel 522, and a first transmission belt 523. The first transmission wheel 521 is fixedly connected to the rotating shaft 512, and the second transmission wheel 522 is rotatably connected to the fixed base 100. The first transmission wheel 521 and the second transmission wheel 522 are arranged at intervals along the first direction X, and the first transmission belt 523 is respectively sleeved on the first transmission wheel 521 and the second transmission wheel 522.

[0038] In this way, when the second transmission wheel 522 rotates, it drives the first transmission wheel 521 to rotate through the first transmission belt 523, thereby driving the rotating shaft 512 to rotate relative to the fixed base 100 by belt drive, which has higher reliability and helps to improve the measurement accuracy of the thickness gauge 10.

[0039] like Figure 1 , Figure 6 and Figure 7 As shown, there are multiple cams 511, multiple shafts 512, and multiple first transmission wheels 521. Multiple cams 511 are arranged at intervals along the first direction X. The first transmission belt 523 is respectively sleeved on multiple first transmission wheels 521. Among the multiple cams 511 arranged at intervals along the first direction X, one cam 511 corresponds to one shaft 512 and one first transmission wheel 521.

[0040] In this way, multiple cams 511 can simultaneously drive the lifting plate 240 to slide relative to the fixed base 100 along the third direction Z, thereby more reliably driving the lifting rod 220 to slide relative to the first sliding member 300 along the third direction Z, which helps to improve the measurement accuracy of the thickness gauge 10.

[0041] like Figure 1 , Figure 6 , Figure 7 and Figure 9 As shown, the first power unit 500 further includes a first driver 531, a first bevel gear 532 and a second bevel gear 533. The first bevel gear 532 is coaxially arranged with the second transmission wheel 522 and is fixedly connected to the second transmission wheel 522. The second bevel gear 533 meshes with the first bevel gear 532. The first driver 531 is disposed on the fixed base 100 and is indirectly or directly connected to the second bevel gear 533.

[0042] It is understandable that the first driver 531 drives the second bevel gear 533 to rotate, which in turn drives the first bevel gear 532 to rotate, thereby enabling the first bevel gear 532 to drive the second transmission wheel 522 to rotate, and in turn enabling the first transmission belt 523 to drive the first transmission wheel 521 to rotate. By setting the first bevel gear 532 and the second bevel gear 533, the angle of power transmission (usually 90°) can be changed, transforming the mechanical space that originally needed to be straight and extended into a vertical or staggered layout, thereby reducing its own space occupation and contributing to a compact design.

[0043] Of course, in the above embodiments, cylindrical gears can be used instead of bevel gears to achieve the same power transmission between the first driver 531 and the second transmission wheel 522.

[0044] like Figure 1 , Figure 4 and Figure 9 As shown, the first power device 500 further includes a third transmission wheel 541, a fourth transmission wheel 542, and a second transmission belt 543. The third transmission wheel 541 and the fourth transmission wheel 542 are rotatably connected to the fixed base 100. The third transmission wheel 541 is coaxially arranged with the second bevel gear 533 and is fixedly connected to the second bevel gear 533. The first driver 531 is connected to the fourth transmission wheel 542. The third transmission wheel 541 and the fourth transmission wheel 542 are arranged at intervals along the first direction X. The second transmission belt 543 is respectively sleeved on the third transmission wheel 541 and the fourth transmission wheel 542.

[0045] In this way, by driving the fourth transmission wheel 542 to rotate through the first driver 531, the second transmission belt 543 drives the third transmission wheel 541 to rotate, which enables power transmission between the first driver 531 and the second bevel gear 533 in a belt drive manner, which has higher reliability and helps to improve the measurement accuracy of the thickness gauge 10.

[0046] In other embodiments, the first power device 500 is a linear motor, electric cylinder, pneumatic cylinder, or other device capable of outputting linear motion, which can also drive the lifting plate 240 to slide relative to the fixed seat 100 in the third direction Z.

[0047] like Figure 1 , Figure 6 and Figure 8 As shown, in some embodiments, the first sliding member 300 is provided with a through sliding hole 310, which extends along the third direction Z. The second sliding member 400 is provided with a connecting hole 410 communicating with the sliding hole 310. The lifting rod 220 passes through the sliding hole 310 and the connecting hole 410 respectively.

[0048] In this way, the lifting rod 220 can slide along the first direction X relative to the fixed base 100 with the first sliding member 300, and can also slide along the third direction Z relative to the first sliding member 300. This allows the detector 230 to slide between the calibration station and the measurement station, avoid the standard piece 210 to prevent structural interference when in the calibration station, and return to its original position when in the measurement station.

[0049] like Figure 1 , Figure 6 and Figure 8 As shown, the first sliding member 300 is further provided with a sliding groove 320 communicating with the sliding hole 310. The sliding groove 320 is disposed towards the detector 230 along the third direction Z. The sliding groove 320 extends along the third direction Z. The part of the second sliding member 400 with the connecting hole 410 is located in the sliding groove 320.

[0050] It is understandable that by setting the groove 320, the stability of the second slider 400 sliding along the third direction Z can be enhanced, and the sliding of the second slider 400 along the second direction Y can be restricted, which helps to reduce the risk of the detector 230 shaking, thereby helping to improve the measurement accuracy of the thickness gauge 10.

[0051] like Figure 1 , Figure 6 and Figure 8 As shown, further, the slide groove 320 passes through the first sliding member 300 along the first direction X. The thickness gauge 10 also includes a limiting sleeve 250. The limiting sleeve 250 is respectively arranged around the first sliding member 300 and the second sliding member 400. The limiting sleeve 250 is fixedly connected to the first sliding member 300 or the second sliding member 400. The limiting sleeve 250 covers both ends of the slide groove 320 along the first direction X.

[0052] Understandably, the groove 320 extends through the first sliding member 300 along the first direction X to facilitate the assembly of the second sliding member 400, thus reducing the assembly difficulty of the second sliding member 400. By setting the limiting sleeves 250 around the first sliding member 300 and the second sliding member 400 respectively, and sealing both ends of the groove 320 along the first direction X, the stability of the second sliding member 400 sliding along the third direction Z can be further enhanced, thereby helping to further reduce the risk of the detector 230 shaking.

[0053] like Figures 1 to 3 as well as Figure 9 and Figure 10As shown, in some embodiments, the fixed base 100 is provided with a first guide groove 110, a second guide groove 120 and a third guide groove 130. The second guide groove 120 is connected to the first guide groove 110 and the third guide groove 130 respectively. The first guide groove 110 and the third guide groove 130 are both extended along the first direction X. The second guide groove 120 is extended along the third direction Z. The third guide groove 130 is positioned relative to the first guide groove 110 and close to the standard piece 210 along the first direction X. The lifting rod 220 passes through one of the first guide groove 110, the second guide groove 120 and the third guide groove 130 along the second direction Y.

[0054] It is understandable that when the lifting rod 220 passes through the first guide groove 110 or the third guide groove 130, the lifting rod 220 slides relative to the fixed seat 100 along the first direction X under the drive of the first sliding member 300, so as to realize the sliding of the detector 230 between the calibration station and the measurement station; when the lifting rod 220 passes through the second guide groove 120, the lifting rod 220 slides relative to the fixed seat 100 along the third direction Z under the drive of the lifting plate 240, so as to realize the raising and lowering of the detector 230.

[0055] like Figures 1 to 3 as well as Figure 9 and Figure 10 As shown, the fixed base 100 is further provided with a lifting groove 140 extending along the third direction Z. The lifting groove 140 is connected to the first guide groove 110, the second guide groove 120 and the third guide groove 130 respectively, and the lifting plate 240 is located in the lifting groove 140. In this way, the lifting plate 240 and the fixed base 100 can be slidably connected along the third direction Z.

[0056] Of course, for the above embodiment, the lifting plate 240 and the fixed seat 100 can also be slidably connected along the third direction Z by other structures. For example, the thickness gauge 10 also includes a slider and a guide rail. The guide rail passes through the slider, extends along the third direction Z and is fixedly connected to the fixed seat 100, and the slider is fixedly connected to the lifting plate 240.

[0057] like Figure 1 As shown, in some embodiments, the thickness gauge 10 further includes a transmitter 260 and a third slider 600. The detector 230 and the transmitter 260 are arranged opposite each other along the third direction Z. The transmitter 260 is fixedly connected to the third slider 600, and the third slider 600 is slidably connected to the fixed base 100 along the first direction X.

[0058] Understandably, when the detector 230 is in the measurement position, the electrode is inserted between the detector 230 and the transmitter 260. The transmitter 260 emits rays to the electrode. When the rays pass through the electrode, they are absorbed and attenuated by the material. The degree of attenuation is related to the thickness of the electrode and the density of the material. The detector 230 receives the intensity of the rays after penetration and performs a conversion, thereby realizing the measurement of the thickness of the electrode.

[0059] like Figure 1 , Figure 4 and Figure 5 As shown, the thickness gauge 10 further includes a second power unit 700, which includes a second driver 710, a synchronous shaft 720, a first transmission mechanism 730, and a second transmission mechanism 740. The second driver 710 is disposed on the fixed base 100 and is indirectly or directly connected to the synchronous shaft 720. The synchronous shaft 720 is rotatably connected to the fixed base 100. The first transmission mechanism 730 is connected to the synchronous shaft 720 and the first sliding member 300 respectively. The second transmission mechanism 740 is connected to the synchronous shaft 720 and the third sliding member 600 respectively.

[0060] It is understandable that when the second driver 710 drives the synchronous shaft 720 to rotate relative to the fixed base 100, the first transmission mechanism 730 drives the first sliding member 300 to slide relative to the fixed base 100 along the first direction X. At the same time, the second transmission mechanism 740 drives the third sliding member 600 to slide relative to the fixed base 100 along the first direction X, thereby realizing that the detector 230 and the transmitter 260 slide synchronously relative to the fixed base 100 along the first direction X, which helps to improve the measurement accuracy of the thickness gauge 10.

[0061] For example, the first driver 531 / second driver 710 can be selected from devices capable of outputting rotational motion, such as rotary motors or drive motors, without specific limitations.

[0062] It should be noted that the first sliding member 300 and the fixed base 100 are slidably connected along the first direction X, and the third sliding member 600 and the fixed base 100 are slidably connected along the first direction X. This can also be achieved by opening a guide groove or by combining a slider and a guide rail. No specific limitation is made here.

[0063] like Figure 4As shown, the first transmission mechanism 730 further includes a fifth transmission wheel 731, a sixth transmission wheel 732, and a third transmission belt 733. The fifth transmission wheel 731 is rotatably connected to the fixed base 100. The sixth transmission wheel 732 is sleeved on the synchronous shaft 720 and fixedly connected to the synchronous shaft 720. The first sliding member 300 is located between the fifth transmission wheel 731 and the sixth transmission wheel 732 along the first direction X. The third transmission belt 733 is sleeved on the fifth transmission wheel 731 and the sixth transmission wheel 732 respectively, and the third transmission belt 733 is fixedly connected to the first sliding member 300.

[0064] In this way, the sixth transmission wheel 732 is driven to rotate by the synchronous shaft 720, so that the third transmission belt 733 drives the first sliding member 300 to slide relative to the fixed seat 100 in the first direction X. This enables the power transmission between the synchronous shaft 720 and the first sliding member 300 by belt drive, which has higher reliability and helps to improve the measurement accuracy of the thickness gauge 10.

[0065] like Figure 5 As shown, the second transmission mechanism 740 further includes a seventh transmission wheel 741, an eighth transmission wheel 742, and a fourth transmission belt 743. The seventh transmission wheel 741 is rotatably connected to the fixed base 100. The eighth transmission wheel 742 is sleeved on the synchronous shaft 720 and fixedly connected to the synchronous shaft 720. The third sliding member 600 is located between the seventh transmission wheel 741 and the eighth transmission wheel 742 along the first direction X. The fourth transmission belt 743 is sleeved on the seventh transmission wheel 741 and the eighth transmission wheel 742 respectively, and the fourth transmission belt 743 is fixedly connected to the third sliding member 600.

[0066] In this way, the synchronous shaft 720 drives the eighth transmission wheel 742 to rotate, so that the fourth transmission belt 743 drives the third sliding member 600 to slide relative to the fixed seat 100 in the first direction X. This enables the power transmission between the synchronous shaft 720 and the third sliding member 600 by belt drive, which has higher reliability and helps to improve the measurement accuracy of the thickness gauge 10.

[0067] Of course, for the two embodiments described above, the first transmission mechanism 730 / second transmission mechanism 740 can also be a combination of bevel gears, lead screws, and lead screw nuts. For example, the first transmission mechanism 730 includes a third bevel gear, a fourth bevel gear, a lead screw, and a lead screw nut. The third bevel gear is sleeved on and fixedly connected to the synchronous shaft 720. The fourth bevel gear meshes with the third bevel gear and is sleeved on and fixedly connected to the lead screw. The lead screw passes through the lead screw nut, and the lead screw nut is fixedly connected to the first sliding member 300. In this way, power transmission between the synchronous shaft 720 and the first sliding member 300 can also be achieved.

[0068] like Figure 4As shown, the second power unit 700 further includes a third transmission mechanism 750, which includes a ninth transmission wheel 751, a tenth transmission wheel 752, and a fifth transmission belt 753. The ninth transmission wheel 751 is sleeved on the synchronous shaft 720 and fixedly connected to the synchronous shaft 720. The tenth transmission wheel 752 is connected to the second driver 710. The ninth transmission wheel 751 and the tenth transmission wheel 752 are arranged at intervals along the second direction Y. The fifth transmission belt 753 is sleeved on the ninth transmission wheel 751 and the tenth transmission wheel 752 respectively.

[0069] In this way, by driving the tenth transmission wheel 752 to rotate through the second driver 710, the fifth transmission belt 753 drives the ninth transmission wheel 751 to rotate, which enables power transmission between the second driver 710 and the synchronous shaft 720 in a belt drive manner, which has higher reliability and thus helps to improve the measurement accuracy of the thickness gauge 10.

[0070] Of course, in the above embodiment, the third transmission mechanism 750 may also include a first gear and a second gear, the first gear being connected to the second driver 710, the second gear meshing with the first gear, and the second gear being sleeved on the synchronous shaft 720 and fixedly connected to the synchronous shaft 720, which can also realize the power transmission between the second driver 710 and the synchronous shaft 720.

[0071] It should be noted that the aforementioned drive wheels can be selected from pulleys, track wheels, sprockets, etc., and the aforementioned drive belts can be selected from belts, tracks, chains, etc., without specific limitations.
