Description

Technical Field

[0001] This invention belongs to the field of carbon fiber plate thickness measurement technology, specifically a device for measuring the thickness of carbon fiber plates. Background Technology

[0002] The background technology for measuring the thickness of carbon fiber sheets mainly involves the fields of composite material manufacturing and quality control. Carbon fiber sheets are valued for their high strength, lightweight, and corrosion resistance.

[0003] When measuring the thickness of carbon fiber sheets, laser detection is required, so the position of the carbon fiber sheets needs to be limited. The use of support components will obstruct part of the carbon fiber sheets, resulting in inaccurate thickness measurement results.

[0004] In view of this, a device for measuring the thickness of carbon fiber plates is proposed. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] Given the following technical problems in the existing technology: When measuring the thickness of carbon fiber plates, laser detection is required, so the position of the carbon fiber plate needs to be limited. However, under the influence of position restriction over a long period of time, the four edges of the carbon fiber plate may loosen, affecting the measurement accuracy. The support component may also obstruct part of the carbon fiber plate, resulting in inaccurate thickness measurement results.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a device for measuring the thickness of carbon fiber plates, comprising a complete machine, a measuring cavity, and a thickness measuring mechanism;

[0008] The measuring cavity is milled on the whole machine, and a door panel is hinged to the opening of the measuring cavity. The whole machine is equipped with control buttons, and the thickness measuring mechanism is disposed in the measuring cavity.

[0009] The thickness measuring mechanism includes an auxiliary component and a measuring component, with the auxiliary component positioned above the measuring component.

[0010] The auxiliary components include a bidirectional lead screw, a guide rod, an adjustment frame, a bearing arm, and contact pads. The bidirectional lead screw is hinged to the whole machine, and the guide rod is fixed to the whole machine. The bidirectional lead screw and the guide rod are installed in parallel. A pair of internal threaded sleeves are threaded on the bidirectional lead screw. A pair of guide sleeves are slidably connected to the guide rod. The bearing arm is installed on the side of the internal threaded sleeves and the guide sleeves. Contact pads are installed at the other end of the bearing arm. The four contact pads contact the edges of the four corners of the carbon fiber plate. The adjustment frame is slidably installed outside the bearing arm.

[0011] The measuring unit includes a threaded rod one, a guide post, a threaded rod two, a laser sensor housing, and a convex ring. The threaded rod one is hinged to the whole machine, and the guide post is fixed to the whole machine. A pair of internal threaded sleeves two are threaded on the threaded rod one, and a pair of guide sleeves two are slidably connected to the guide post. The internal threaded sleeves two and the guide sleeves two are jointly equipped with a support frame. The threaded rod two is hinged at the middle position of the support frame, and an internal threaded sleeve three is threaded on the threaded rod two. The laser sensor housing is installed on the top surface of the internal threaded sleeve three.

[0012] As a preferred technical solution for a device for measuring the thickness of carbon fiber plates, one end of the bidirectional lead screw is equipped with a drive motor. A lower positioning plate and an upper positioning plate are installed on opposite faces of a pair of internal threaded sleeves and a guide sleeve. The upper positioning plate is located above the lower positioning plate and is parallel to the lower positioning plate. A linkage frame is telescopically mounted on the lower positioning plate. A linkage plate is installed at the part of the linkage frame that extends out of the lower positioning plate. An arc plate is installed at the edge of the linkage plate. When the laser sensor housing is displaced to the position of the adjustment frame, the convex ring will act on the arc plate to lift the position of the linkage plate upward.

[0013] As a preferred technical solution for a device for measuring the thickness of carbon fiber plates, a spring is connected between the linkage plate and the lower positioning plate. When the positions of the convex ring and the arc plate do not correspond, the linkage plate can be easily reset by the action of the spring.

[0014] As a preferred technical solution for a device for measuring the thickness of carbon fiber plates, a gear is hinged to the back of the upper positioning plate, the gear meshes with a linkage frame, wherein the side of the linkage frame facing the gear is milled with teeth, and a U-frame is laterally telescopically mounted on the upper positioning plate, the bottom surface of the U-frame is milled with teeth, the U-frame meshes with the gear, and when the linkage plate is subjected to telescopic movement, the linkage frame and the gear mesh, causing the gear to rotate, and the rotating gear meshes with the U-frame to perform lateral telescopic movement.

[0015] As a preferred technical solution for a device for measuring the thickness of carbon fiber plates, a driven plate is installed on the upper part of the U-frame. The driven plate is connected to the adjustment frame, and the lateral movement of the U-frame can move the driven plate and the adjustment frame together.

[0016] As a preferred technical solution for a device for measuring the thickness of carbon fiber plates, the contact pad is provided with a protrusion on the side facing the carbon fiber plate, wherein the protrusion can increase the contact friction between the contact pad and the carbon fiber plate.

[0017] As a preferred technical solution for a device for measuring the thickness of carbon fiber plates, the adjustment frame consists of an arc section and a U section. The U section extends and retracts on the support arm and is connected to the driven plate. The arc section is installed at the opening of the U section. The U section can ensure and adjust the parallel state of the carbon fiber plate during measurement, thereby improving the accuracy of the measurement.

[0018] As a preferred technical solution for a device for measuring the thickness of carbon fiber plates, a drive motor is installed at one end of the threaded rod, and a drive motor is installed on one side of the support frame. The drive motor controls the threaded rod to rotate. A guide plate is installed on the side of the support frame, and the side of the internal threaded sleeve fits against the inner edge of the guide plate, so that the internal threaded sleeve will not rotate during the position movement.

[0019] As a preferred technical solution for a device for measuring the thickness of carbon fiber plates, a laser displacement sensor is installed in the housing of the laser sensor, and a set of threaded rods is also installed on the top of the inner edge of the measuring cavity. The threaded rods do not require guide posts, and the carbon fiber plates are subsequently measured by the corresponding laser displacement sensors.

[0020] As a preferred technical solution for a device for measuring the thickness of carbon fiber plates, a convex ring is provided on the outer periphery of the laser sensor housing, which is used to activate the linkage plate to perform lifting and lowering movements when the laser sensor housing moves to the corresponding position of the adjustment frame.

[0021] The beneficial effects of this invention are:

[0022] 1. This device for measuring the thickness of carbon fiber plates enables the laser sensor housing to move in the X and Y directions via threaded rod one and threaded rod two, facilitating comprehensive thickness measurement of the carbon fiber plate. Simultaneously, when the laser sensor housing moves to the position of the adjustment frame, the adjustment frame partially obstructs the carbon fiber plate, creating blind spots during measurement. The convex ring acts on the linkage plate via the arc plate. Under the linkage of the linkage frame, gears, and U-frame, the linkage plate ensures that the individual adjustment frame at the corresponding position does not limit the movement of the carbon fiber plate. Because corner detection is faster, and with the constraints of the other three components, the carbon fiber plate will not fall at one corner, affecting the accuracy of the measurement structure. This allows for accurate and comprehensive thickness measurement of the carbon fiber plate without blind spots.

[0023] 2. This device for measuring the thickness of carbon fiber plates allows the carbon fiber plates to be placed horizontally by means of the arc section and the contact pad. The arc section can also be adjusted to the same height for lower parts of the carbon fiber plates, thereby improving the accuracy of the measurement structure.

The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0040] Reference Figures 1 to 6 The auxiliary components include a bidirectional lead screw 200, a guide rod 201, an adjustment frame 216, a bearing arm 217, and contact pads 218.

This embodiment differs from the previous embodiment in that: the measuring unit includes a threaded rod 300, a guide post 301, a threaded rod 306, a laser sensor housing 309, and a convex ring 310. The threaded rod 300 is hinged in the whole machine 100, and the guide post 301 is fixed in the whole machine 100. A pair of internal threaded sleeves 302 are threaded on the threaded rod 300.

[0049] One end of the threaded rod 300 is equipped with a drive motor 304, and one side of the support frame 305 is equipped with a drive motor 307. The drive motor 307 controls the threaded rod 306 to rotate. A guide plate 311 is installed on the side of the support frame 305. The side of the internal threaded sleeve 308 fits against the inner edge of the guide plate 311, so that the internal threaded sleeve 308 will not rotate during the position movement.

[0050] A laser displacement sensor is installed in the laser sensor housing 309. A set of threaded rods 300 are also installed on the top of the inner edge of the measuring cavity 102.
