Description

Technical Field

[0001] This utility model relates to the field of glass thickness measurement technology, specifically to a coating glass thickness measurement device. Background Technology

[0002] Glass is a material with extremely high utilization rate in modern society. Before various types of glass leave the factory, it is often necessary to test the thickness of the glass. The thickness of glass is measured in order to calculate the performance of glass in terms of heat transfer capacity, light transmittance and total solar energy transmittance. The production and use requirements of glass with different thicknesses are different.

[0003] Currently, there are generally two methods for measuring glass thickness. For small pieces of glass, the glass is usually placed in a thickness measuring device, which clamps and positions the glass before measuring the thickness. For larger pieces of glass, the thickness is usually measured manually using vernier calipers or micrometers. Most glass thickness measuring devices are cumbersome to operate, requiring the glass to be placed flat and the device data to be adjusted, which requires a large amount of manpower. Vernier caliper measurement requires manual reading, which may result in significant errors due to reading mistakes, leading to incorrect recording of the glass thickness.

[0004] For example, Chinese patent CN221685415U discloses a glass thickness measuring device, including a protective frame with a bidirectional threaded rod inside. The outer surface of the protective frame has an upper clamping member, a lower clamping member, a handle, and a control box. Laser sensors are installed at both the upper and lower parts of the protective frame, and parallel circular plates are installed on both the upper and lower clamping members. This glass thickness measuring device first stably clamps the glass using the parallel circular plates. Rubber pads reduce wear on the glass during the measurement process, and a pressure sensor inside the rubber pads is electrically connected to the controller of a rotary motor. Once stable clamping is detected, the clamping members stop moving to avoid damage to the glass. The clamping ensures that the angle of the glass to be measured is perpendicular to the laser sensor. The laser sensor emits a laser beam to measure the thickness of the glass, and its signal processor directly displays the data on the control box's display screen. This device is not only simple to operate but also significantly improves the accuracy and measurement efficiency compared to traditional methods.

[0005] However, dust in the environment can easily adhere to the glass, causing it to slip when clamped, which can affect the measurement results. Utility Model Content

[0006] The purpose of this invention is to provide a coating glass thickness measuring device to solve the problem mentioned in the background art that dust in the environment easily adheres to the glass, causing the glass to slip and affecting the measurement results during clamping.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a coating glass thickness measuring device, comprising a frame, wherein a fixing device is provided inside the frame;

[0008] The fixing device includes a lead screw motor, a bidirectional lead screw, a lead screw nut, a limiting groove, a positioning post, a fixing block, a fixing plate, and a fan. The lead screw motor is mounted on top of the frame. The bidirectional lead screw is connected to the output end of the lead screw motor.

The positioning post is fixedly connected to the inside of the frame and located inside the limiting groove. A slider is slidably connected to the outer surface of the positioning post. The slider is fixedly connected to one side of the fixing block. The lead screw nut is fixedly connected to one side of the fixing block. The fixing plate is fixedly connected to the side of the fixing block away from the fixing surface. The lead screw motor drives the bidirectional lead screw to rotate, causing the fixing plates and fixing blocks on the upper and lower sides inside the frame to move closer or further apart to fix or release the coated glass. The fan blows away dust from the glass surface to prevent slippage during fixing.

[0009] Preferably, the fixing surface of the fixing block has two grooves, and the fixing block has a through hole connecting the grooves. A suction cup is fixedly connected to one groove of the fixing surface of the fixing block, and a return spring is fixedly connected to the other groove inside the fixing block.

When fixing, the air inside the fixing block flows out from the groove where the suction cup is located to clean the dust on the glass surface and improve the fixing effect. When the fixing is released, the air squeezes the baffle into the fixing block. When the air pressure inside and outside the fixing block is balanced, the baffle resets under the action of the return spring and re-blocks the groove.

[0010] Preferably, a threaded hole is provided on the top of the frame, and the lead screw motor is connected to the frame by bolt thread through the threaded hole, which facilitates the maintenance and replacement of the lead screw motor and improves the convenience of the device.

[0012] Preferably, an ultrasonic detector is fixedly installed on the upper right side inside the frame, which can detect whether the bubble content inside the glass meets the standard.

[0013] Preferably, a conveyor motor is fixedly installed on the left side of the front of the frame, and the output end of the conveyor motor is connected to a drive roller. A driven roller is rotatably connected inside the frame to the right of the drive roller. A transmission belt is connected to the outer surfaces of the drive roller and the driven roller. A detector is fixedly installed on the upper part of the frame. The detector is located to the left of the fixing device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Addressing the problem that dust easily adheres to glass in the environment, causing slippage during clamping and affecting measurement results, this example provides a coated glass thickness measuring device. Please refer to [link to relevant documentation]. Figures 1-5 An embodiment provides a coating glass thickness measuring device. This coating glass thickness measuring device includes a frame 1, and a fixing device is installed inside the frame 1;

[0026] The fixing device includes a lead screw motor 2, a bidirectional lead screw 201, a lead screw nut 202, a limiting groove 203, a positioning column 204, a fixing block 205, a fixing plate 206, and a fan 207. The lead screw motor 2 is installed above the frame 1. The bidirectional lead screw 201 is connected to the output end of the lead screw motor 2. The lead screw nut 202 is threaded to the outer surface of the bidirectional lead screw 201 and located inside the limiting groove 203. The limiting groove 203 is fixedly connected to the inside of the frame 1. The positioning column 204 is fixedly connected to the inside of the frame 1 and located inside the limiting groove 203. A slider is slidably connected to the outer surface of the positioning column 204. The slider is fixedly connected to one side of the fixing block 205. The lead screw nut 202 is fixedly connected to one side of the fixing block 205. The fixing plate 206 is fixedly connected to the side of the fixing block 205 away from the fixing surface.

[0027] The fixing block 205 has two grooves on its fixing surface. The fixing block 205 has a through hole that connects the grooves. A suction cup 2051 is fixedly connected to one groove on the fixing surface of the fixing block 205. A return spring 2052 is fixedly connected to the other groove inside the fixing block 205. A baffle 2053 is fixedly connected to the other end of the return spring 2052.

[0028] In this embodiment, the lead screw motor 2 drives the bidirectional lead screw 201 to rotate, causing the fixing plates 206 and fixing blocks 205 on the upper and lower sides of the frame 1 to move closer or further apart to fix or release the coated glass. The fan 207 blows away the dust on the glass surface to prevent slippage during fixation. During fixation, the air inside the fixing block 205 flows out from the groove where the suction cup 2051 is located to clean the dust on the glass surface and improve the fixation effect. When the fixation is released, the air squeezes the baffle 2053 into the fixing block 205. When the air pressure inside and outside the fixing block 205 is balanced, the baffle 2053 is reset under the action of the return spring 2052 and re-blocks the groove.

[0029] Example 2: Based on Example 1, a ranging device is provided on the right side inside the frame 1. The ranging device includes a laser rangefinder 6, a mounting plate 601, a damper 602, a partition 603, a shock-absorbing spring 604, and a base plate 605. The base plate 605 is fixedly connected to the right side inside the frame 1, the shock-absorbing spring 604 is fixedly connected to one side of the base plate 605, the partition 603 is fixedly connected to the other end of the shock-absorbing spring 604, the damper 602 is fixedly connected to one side of the partition 603, the mounting plate 601 is fixedly connected to one side of the damper 602, and the laser rangefinder 6 is fixedly connected to one side of the mounting plate 601.

[0030] A conveyor motor 4 is fixedly installed on the left side of the front of the frame 1. The output end of the conveyor motor 4 is connected to the drive roller 401. Inside the frame 1, a driven roller 402 is rotatably connected to the right side of the drive roller 401. A transmission belt 403 is connected to the outer surface of the drive roller 401 and the driven roller 402. A detector 404 is fixedly installed on the upper part of the inside of the frame 1. The detector 404 is located on the left side of the fixed device.

[0031] In this embodiment, the damper 602 and the shock-absorbing spring 604 work together to reduce the influence of environmental vibration on the laser rangefinder 6, making the measurement results more accurate. The glass is transported by the conveying motor 4 driving the active roller 401, the driven roller 402 and the transmission belt 403 to rotate. When the detector 404 detects the glass for a certain period of time, the fixing device is activated to fix the glass.

[0032] Working Principle: The lead screw motor 2 drives the bidirectional lead screw 201 to rotate, causing the fixing plates 206 and fixing blocks 205 on the upper and lower sides of the frame 1 to move closer or further apart, fixing or releasing the coated glass. The fan 207 blows away dust from the glass surface to prevent slippage during fixing. During fixing, air inside the fixing block 205 flows out from the groove where the suction cup 2051 is located to clean the dust on the glass surface and improve the fixing effect. When releasing the fixing, the air compresses the baffle 2053 into the fixing block 205. After the air pressure inside and outside the fixing block 205 is balanced, the baffle 2053 is reset by the return spring 2052 and re-blocks the groove. The damper 602 and the shock-absorbing spring 604 work together to reduce the influence of environmental vibration on the laser rangefinder 6, making the measurement results more accurate. The conveyor motor 4 drives the active roller 401, driven roller 402 and transmission belt 403 to rotate to transport the glass. When the detector 404 detects the glass for a certain period of time, the fixing device is activated to fix the glass.
