Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of glass detection, specifically, the utility model relates to a lamp box for observing stress spot of toughened glass. BACKGROUND

[0002] In the modern glass processing industry, toughened glass is widely used in construction, automobiles and other fields due to its high strength and safety. When placed under polarized light, the color and brightness changes in different areas of the glass can be observed, which is the stress spot of the toughened glass. An important quality control indicator in the toughened process is the observation of stress spot, which is the key to evaluating the uniformity of internal stress distribution of the toughened glass.

[0003] The traditional stress spot observation method relies on natural sunlight and manual operation, which has many inconveniences and limitations. In the traditional method, the observation of stress spot needs to be carried out under specific conditions, usually by transporting the toughened glass to the door of the workshop, using the natural sunlight to irradiate, and laying black cloth under the glass to enhance the contrast. This method not only consumes time and effort, but also is limited by weather and time, and cannot realize real-time monitoring and adjustment, which seriously affects the production efficiency and consistency of product quality. In addition, due to the delay of observation results, the adjustment of production parameters cannot take effect immediately, which prolongs the feedback and optimization period in the production process, increasing the production cost and time cost.

[0004] 1. Dependence on natural light: The traditional stress spot observation method relies heavily on the irradiation of natural sunlight. This not only limits the observation time (which can only be done during the day), but also is affected by weather conditions (such as overcast weather which will affect the observation effect).

[0005] 2. Manual operation is complicated: During the observation process, the glass needs to be manually transported to a specific position, and black cloth needs to be laid under the glass, and a polarizing lens is used for observation. This series of operations not only consumes time and effort, but also increases the labor cost and the risk of operation errors.

[0006] 3. Poor real-time performance: Due to the delay of the observation process, the adjustment of production parameters cannot take effect immediately. This leads to the prolongation of the feedback and optimization period in the production process, affecting the production efficiency and consistency of product quality.

[0007] 4. Low production efficiency: The traditional observation method cannot be carried out in real time on the production line, and the glass needs to be transported and set again after toughening, which not only increases the production time, but also may cause damage to the glass during transportation.

[0008] 5. Difficulty in quality control: Due to the inability to monitor and adjust in real time, the traditional observation method cannot guarantee the quality stability of each batch of toughened glass, increasing the difficulty and cost of quality control.

[0009] 6. Environmental limitations: traditional observation methods need to be carried out in a specific environment, such as the door of a workshop, which limits the flexibility and applicability of observation, and is not conducive to the overall optimization and automatic upgrading of the production line.

[0031] The specific embodiments of the present application are further described in detail below with reference to the drawings, and the purpose is to help the technical personnel in the field to have a more complete, accurate and in-depth understanding of the inventive concept and technical scheme of the present application, and to help its implementation.

[0032] As Figures 1 to 3 shown, the toughened glass stress spot observation lamp box, the lamp box 1 includes the lower piece table 2, the LED lamp tube 3 is equipped in the lamp box 1, the lamp box 1 side is sequentially provided with the frosted glass 4 and the polaroid 5 from inside to outside, the lower piece table 2 side is equipped with the polaroid 6.

[0033] The lamp box 1 sets up the lower piece table 2 and can receive the incoming glass, so that the whole can be connected with the production line, improves the production efficiency, the principle of observing the glass stress spot is as follows: the combination of frosted white glass and polaroid 5: frosted white glass is used to scatter light uniformly, and polaroid 5 is used to convert scattered light into polarized light, which ensures the consistency and stability of polarized light. Use LED lamp tube 3 as light source, frosted white glass has the characteristics of scattering light, which can uniformly scatter the light emitted by LED lamp tube 3 to all directions. This kind of uniform scattering light is similar to natural light, which has multi-directional light wave vibration, which provides the basis for subsequent polarization processing. Polaroid 5 is an optical element that can selectively transmit light waves in a specific direction. When the uniformly scattered light passes through the polaroid 5, the polaroid 5 will filter out all the light wave vibrations perpendicular to the transmission axis, and only allow the light wave vibrations parallel to the transmission axis to pass through. In this way, the originally multi-directional vibration light is converted into single-directional vibration polarized light. The light emitted by LED lamp tube 3 is monochromatic itself, and has high brightness and stability, so LED lamp tube 3 can provide stable and sufficient light source to ensure that polaroid 5 can effectively produce polarized light. The polarization of sunlight is due to the scattering of molecules and particles in the atmosphere. This scattering makes part of the light become polarized light. In the above artificial light source, through the scattering effect of frosted white glass and the selective transmission effect of polaroid 5, the scattering and polarization process in natural light can be simulated, so as to produce polarized light similar to sunlight. Therefore, it can achieve the stability and consistency of observation without being limited by natural light and weather conditions.

The stress spot effect of the tempered glass surface is observed through the polarizing lens 6, so that online real-time monitoring is realized, and the production efficiency is improved. When observing, the operator stands on one side of the light box 1, and the stress spot effect of the tempered glass can be directly observed through the polarizing lens 6. If a monitoring camera is used instead of the polarizing lens 6, a polarizing sheet 5 needs to be pasted in front of the lens of the monitoring camera, so that online observation of the stress spot can be realized.

[0035] As shown in the drawings, Figure 1 One end of the lower sheet table 2 is provided with a baffle 8, and the baffle 8 is connected with the light box 1 to form an L-shaped structure.

The bottom of the connecting rod 12 is inserted into the support rod 11, and the two are locked and fixed by the bolt 13, so that the position of the polarizing lens 6 is stable. The bottom of the polarizing lens 6 is inserted into the connecting rod 12 to satisfy the rotation of the polarizing lens 6, and the two can also be connected by a bearing.
