[0028] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0029] Please refer to Figures 1 to 5The plate thickness measuring mechanism includes a control module, a loading platform, a lifting drive, a pressing plate and a thickness measuring sensing component. The pressing plate is arranged above the loading platform. The lifting drive is connected to the pressing plate to drive the pressing plate to move up and down. The thickness measuring sensing component includes two contact sensors respectively arranged above and below the loading platform. The contact sensor has a retractable probe. The lifting drive and the two contact sensors are electrically connected to the control module.

[0030] From the above description, it can be seen that the beneficial effect of the utility model is that: the plate thickness measuring mechanism uses a loading platform to carry the incoming plate material, and the pressing plate flattens the plate under the drive of the lifting drive member so that the probe of the contact sensor can contact the flat plate surface, and then the probes of the two contact sensors of the thickness sensing component move toward each other until they respectively touch the upper and lower surfaces of the plate, and the control module calculates the displacement data of the probes of the two contact sensors to obtain the thickness value. The plate thickness measuring mechanism has high measurement accuracy and fast measurement speed, and can meet the market's increasingly high accuracy and production efficiency requirements for plates.

[0031] Furthermore, there are multiple thickness sensing components.

[0032] From the above description, it can be seen that the control module can average the measurement data of multiple thickness sensing components, thereby improving the accuracy of the measurement results; or, multiple thickness sensing components can respectively measure the thickness of the plate at different locations, which is conducive to improving measurement efficiency.

[0033] Furthermore, the number of the thickness sensing components is three.

[0034] It can be seen from the above description that providing three thickness sensing components can ensure the accuracy of the measurement result and avoid excessive equipment cost of the thickness measuring mechanism.

[0035] Furthermore, the pressing plate is provided with a first through hole for the contact sensor to pass through.

[0036] From the above description, it can be seen that the partial area of ​​the plate below the first through hole is flatter than the partial area of ​​the plate on the side of the pressure plate, so making the contact sensor contact the partial area of ​​the plate below the first through hole is beneficial to improving measurement accuracy.

[0037] Furthermore, a second through hole for the contact sensor to pass through is formed on the loading platform.

[0038] It can be seen from the above description that the contact sensor can be arranged directly below the loading platform, which is beneficial to reducing the footprint of the plate thickness measuring mechanism.

[0039] Furthermore, the bottom edge of the pressing plate is rounded.

[0040] It can be seen from the above description that the rounded corner structure makes it difficult for the pressing plate to scratch or damage the plate.

[0041] Furthermore, the lifting drive member is a linear cylinder.

[0042] As can be seen from the above description, the lifting drive member is easy to obtain and use.

[0043] Furthermore, a limiting strip is respectively provided on both sides of the loading platform.

[0044] It can be seen from the above description that the limit strip can limit the moving direction of the plate to prevent the position of the plate from being offset.

[0045] Furthermore, it also includes a locking screw. A long hole is provided on the limit bar, the length direction of the long hole is parallel to the width direction of the plate, and a threaded hole is provided on the loading platform corresponding to the long hole. The locking screw passes through the long hole and cooperates with the threaded hole.

[0046] It can be seen from the above description that the relative positions of the two limit bars and the loading platform in the width direction of the plate can be changed, so that the gap between the two limit bars can be adapted to the width of plates of different models.

[0047] Furthermore, at least one end of the loading platform is provided with a pinch roller.

[0048] It can be seen from the above description that the pinch rollers are used to convey the plates.

[0049] Please refer to Figures 1 to 5 , Embodiment 1 of the present utility model is: a plate thickness measuring mechanism, used for accurately and efficiently measuring the thickness of a plate.

[0050] The plate thickness measuring mechanism includes a control module, a loading platform, a lifting drive, a pressure plate and a thickness measuring sensing component. The pressure plate is arranged above the loading platform. The lifting drive is connected to the pressure plate to drive the pressure plate to move up and down. The thickness measuring sensing component includes two contact sensors respectively arranged above and below the loading platform. The contact sensor has a retractable probe. The lifting drive and the two contact sensors are electrically connected to the control module.

[0051] Specifically, the loading platform includes a loading plate, a bottom plate and two side plates, the two side plates are fixedly connected to the bottom plate, and the two sides of the loading plate are fixedly connected to the two side plates respectively. A first bracket is provided on the loading platform, the first bracket is straddled above the loading plate, and the lifting drive is fixedly connected to the first bracket. In this embodiment, the lifting drive is a linear cylinder. The pressure plate is in the shape of a rectangular body. A second bracket is provided on the loading platform, the second bracket is straddled above the loading plate, and the contact sensor located above the loading platform is fixedly connected to the second bracket. A mounting block is provided below the loading plate of the loading platform, and the contact sensor located above the loading platform is fixedly connected to the mounting block, and an avoidance window is opened on the bottom plate of the loading platform corresponding to the contact sensor. The probes of the two contact sensors of the thickness sensing assembly are symmetrically arranged relative to the plate. In this embodiment, the two contact sensors of the thickness sensing assembly are preferably GT2-A12KL sensor heads of the same model, the detection method is Scale Shot SystemII, the detection range is 12mm, the resolution is 0.1μm, the accuracy is 1μm, the measurement force is 0.2-0.4N, and the difference is that the probe of one contact sensor uses a flat contact head, and the probe of the other contact sensor uses a standard spherical contact head. The control module is used to control the movement of the lifting drive and the probe of the contact sensor, and to process and output the displacement data of the probes of the two contact sensors. The basic principle of the thickness measurement method is that the probes of the two contact sensors of the thickness sensing assembly contact the surface of the plate respectively, and the displacement distances A and B of the two probes are obtained, while the distance between the two contact sensors is a fixed value C, and the plate thickness value is C-(A+B).

[0052] like Figure 1 and Figure 2 As shown, there are multiple thickness sensing components. Multiple thickness sensing components are arranged equidistantly along the width direction of the plate. In this embodiment, there are three thickness sensing components, that is, there are six contact sensors, which are evenly divided into three groups. In other embodiments, the number of thickness sensing components can be set to two, four or more.

[0053] like Figure 3 and Figure 4 As shown, the pressure plate is provided with a first through hole for the contact sensor to pass through. It is easy to understand that the partial area of ​​the plate below the first through hole is smoother than the partial area of ​​the plate on the side of the pressure plate, so that the contact sensor contacts the partial area of ​​the plate below the first through hole, which is conducive to improving the measurement accuracy.

[0054] like Figure 3 and Figure 5 As shown, a second through hole for the contact sensor to pass through is provided on the material loading plate of the material loading platform. It is easy to understand that the contact sensor can be arranged directly below the material loading plate of the material loading platform, which is conducive to reducing the floor space occupied by the plate thickness measuring mechanism.

[0055] like Figure 4 As shown, in order to prevent the pressing plate from crushing or scratching the sheet material, the bottom edge of the pressing plate is rounded.

[0056] A limiting bar is respectively provided on both sides of the loading platform. Specifically, the two limiting bars are respectively fixedly connected to both sides of the top of the loading plate, the two limiting bars are symmetrically arranged, and the loading plate and the two limiting bars form a material trough for the plate to pass through.

[0057] like Figure 5 As shown, the plate thickness measuring mechanism also includes a locking screw, a long hole is provided on the limit bar, the length direction of the long hole is parallel to the width direction of the plate, a threaded hole is provided on the loading platform corresponding to the long hole, and the locking screw passes through the long hole and cooperates with the threaded hole. Specifically, the long hole is oblong, and three long holes are provided on each limit bar, and the number of long holes, locking screws and threaded holes is set in a one-to-one correspondence. It is easy to understand that the relative position of the two limit bars and the loading platform in the width direction of the plate can be changed, so that the gap between the two limit bars can be adapted to the width of plates of different models.

[0058] In order to convey the plate, the plate moves along the material trough surrounded by the material carrier plate and the two limit strips, and a set of pinch rollers are respectively provided at both ends of the material carrier. In other embodiments, it is also feasible to provide pinch rollers at only one end of the material carrier.

[0059] In summary, the plate thickness measuring mechanism provided by the utility model uses a loading platform to carry incoming plate materials. The pressing plate flattens the plate under the drive of the lifting drive member so that the probe of the contact sensor can contact the flat surface of the plate. Then, the probes of the two contact sensors of the thickness sensing component move toward each other until they respectively touch the upper and lower surfaces of the plate. The control module calculates the displacement data of the two contact sensor probes to obtain the thickness value. The measurement accuracy is high and the measurement speed is fast, which can meet the market's increasingly high accuracy and production efficiency requirements for plates. The control module can average the measurement data of multiple thickness sensing components to improve the accuracy of the measurement results; or, multiple thickness sensing components can respectively measure the thickness of the plate at different parts, which is conducive to improving the measurement efficiency. The rounded corner structure makes it difficult for the pressing plate to scratch or damage the plate.
