Description

Technical Field

[0001] The utility model relates to the technical field of glass production, and particularly relates to a handheld glass appearance inspection device. Background Art

[0002] Glass has been popularized in all aspects of people's lives. Glass processing generally includes steps such as selecting the original sheet, cutting the glass size, grinding and chamfering the glass edges, tempering, silk screening, and cleaning, detecting, and packaging. After the glass is processed, quality inspection is required, and among them, the appearance inspection of the glass is very important for ensuring the glass quality. Existing glass manufacturers mostly use visual inspection or customized special equipment when conducting glass appearance inspection. When visually inspecting the glass surface under natural light or sunlight, errors are likely to occur due to the influence of the light angle and light intensity, which easily leads to missed inspections and misjudgments, and the work efficiency is relatively low. Since the glass is easily left with impurities such as grinding powder and water stains on its surface after grinding and processing, it affects the detection accuracy of customized equipment.

[0003] At the same time, currently on the market, it is impossible to use a single lens to perform appearance inspection on items with a relatively large volume. If it is necessary to apply it to the appearance inspection of large-sized glass or the appearance inspection of the edge positions, multi-lens and multi-angle inspections are required, resulting in the customized equipment being too large in volume and expensive, and requiring special maintenance later. Moreover, the operation of the detector is cumbersome and requires special training to operate. Therefore, the applicant proposes a handheld appearance inspection device with good versatility.

[0022] The following describes the preferred embodiments of the present utility model with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0023] Among them, the same reference numerals in the drawings all refer to the same components.

[0024] As Figures 1-5 shown, the present utility model provides a handheld glass appearance inspection device.

[0025] The usage method of the present utility model is as follows:

[0026] 1. The present utility model includes an irradiation part 1 and a handheld part 2. The handheld part 2 is located at the lower end of the irradiation part 1. Hold the handheld part 2, and perform appearance inspection on the irradiated object through the irradiation part 1 to identify the appearance defects of the glass.

[0027] 2. As Figures 3-5 shown, the irradiation part 1 includes an outer cover 3 and an LED light strip 4, an LED light board 5, a light guide plate 6 and a diffuser plate 7 arranged inside the outer cover 3. A number of LED lamp beads are provided on the LED light strip 4; the LED light strip 4 faces the inside of the outer cover 3, and the light emitted by the LED light strip 4 irradiates the center of the light guide plate 6 from the side; the LED light board 5, the light guide plate 6 and the diffuser plate 7 are detachably connected to the inside of the outer cover 3 in sequence from the inside to the outside. The LED light board 5 is composed of 4 rectangular LED boards of the same size and is fixed to the innermost layer of the outer cover 3 by a snap connection method. The light guide plate 6 is cuboid in shape and is located directly above the light board 5. The periphery of the light guide plate 6 is covered by the LED light strip 4, and the diffuser plate 7 completely covers the upper part of the light guide plate 6. The light emitted by the LED light strip 4 and the LED light board 5 will first enter the surface of the light guide plate 6, and the reflected light will spread in all directions. Through various light guide points of different densities and sizes on the light guide plate 6, the light guide plate 6 can emit light evenly, improving the light use efficiency; then the light enters the diffuser plate 7, and through continuous refraction, reflection and scattering, the propagation direction of the light is adjusted to achieve a good optical scattering effect; in practical applications, high-power LED light strips 4 and LED light boards 5 can also be replaced according to the needs of the detection environment to increase the light intensity.

[0028] 3. The handheld part 2 includes a handle housing 8, a battery 10 arranged below the handle housing 8 and a switch 9 for controlling the on / off of the LED light strip 4 and the LED light board 5. As Figure 5 shown, the battery 10 is electrically connected to the LED light strip 4 and the LED light board 5 through the switch 9. Preferably, a charging port can be provided at the bottom end of the handheld part 2 to charge the battery 10. Since the present utility model has a built-in battery 10, button control irradiation can be achieved without external devices and connection wires, and the use environment is more flexible; preferably, the surface of the handle housing 8 is arc-shaped, adapting to the arc of the human palm, making the human grip more comfortable. Preferably, the handle housing 8 is fixed to the outer cover 3 by a threaded connection.

[0029] Furthermore, as Figure 5As shown, the LED strip 4 is connected end to end to form a closed loop, and the LED lamp beads are evenly arranged on the LED strip 4 at equal intervals, so that light enters the light guide plate 6 evenly from the side, increasing the uniformity and consistency of the side light.

[0030] Furthermore, as Figure 2 shown, the top of the outer cover 3 is provided with a hanging ear 11 for hanging the outer cover. Preferably, a round hole is provided in the middle of the hanging ear 11, which is convenient for the hanging and storage of the appearance inspection device. Preferably, the hanging ear 3 is fixedly connected to the outer cover 3 by threaded connection.

[0031] Furthermore, as Figures 3-4 shown, the end of the outer cover 3 is provided with a front cover 12 for limiting and fixing the LED strip 4 and the diffuser plate 7, avoiding the displacement of the LED strip 4 and the diffuser plate during the process of holding and moving by hand. Preferably, the front cover 12 is fixedly connected to the outer cover 3 by threaded connection.

[0032] Furthermore, the light guide plate 6 is arranged between the LED lamp board 5 and the diffuser plate 7. As Figures 2-4 shown, when the switch 9 is pressed, the LED strip 4 and the LED lamp board 5 emit light simultaneously. The light emitted by the LED strip 4 and the LED lamp board 5 enters the diffuser plate 7 evenly after being refracted and reflected by the light guide plate 6. Through the further reflection and refraction of the diffuser plate 7, the uniformity and consistency of the scattered light are good, and good visual effects can be obtained when irradiating the item to be detected from any angle, which is convenient for the operator to check the appearance of the item.

[0033] Furthermore, the material of the diffuser plate 7 is optical grade acrylic, which has good wear resistance and high light transmittance, and has a good scattering effect on light.

[0034] The utility model replaces the existing customized fixed structure with a handheld structure, which is convenient to operate and easy to use, and has a lower cost; the appearance of items of different sizes can be detected at specific or non-specific positions through the handheld device, the detection operation is convenient, and the accuracy is high.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the utility model and are not used to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
