Description

Technical Field

[0001] The utility model relates to the technical field of glass tempering, in particular to a glass tempering production device. Background Art

[0002] The current glass tempering production equipment generally includes an upper section, a heating section, an air grid section and a lower section. The glass is loaded and transported through the upper section, transported to the heating section for heating, and then transported to the air grid section for quenching. Thereafter, it is transported to the lower section for unloading and transporting to complete the glass tempering production.

[0003] However, Zhishang fragmented glass needs manual inspection, which requires operators to have rich experience and a high sense of responsibility. However, due to various reasons, missed inspections and misdetections are often seen, wasting manpower and material resources.

[0004] The heating section currently mostly uses the indirect temperature measurement method of thermocouples. By measuring the temperature near the glass, the temperature of the glass itself is indirectly estimated. This method cannot provide timely feedback on the temperature of the glass itself, but cannot adjust the heating parameters in time, resulting in high energy consumption in the heating section.

[0005] Currently, there are few temperature measuring components in the wind grid section, and the parameters of the wind grid are often estimated based on the test data of the finished glass. Therefore, the adjustment of the wind grid section parameters is rather complicated. Especially when changing the type of tempered glass, it is often necessary to repeatedly produce several furnaces of glass before the parameters of the heating section and the wind grid section can be adjusted to a reasonable range, wasting more manpower and material resources.

[0006] The next section also requires manual inspection of finished glass defects, resulting in low work efficiency and frequent false inspections. Once unqualified products appear, manual statistics of production status and adjustment of production quantities are required, which is inefficient and prone to errors. Utility Model Content

[0007] In order to overcome at least one of the defects described in the above-mentioned prior art, the utility model provides a glass tempering glass production equipment, which can be respectively provided with a first detection component and a second detection component in the heating section and the wind grid section for detecting the temperature and position of the glass, so as to timely adjust the heating temperature and the cooling temperature according to the temperature and position of the glass.

[0008] The technical solution adopted by the utility model to solve the problem is:

[0009] A glass tempering production equipment, comprising:

[0010] The upper segment includes a first conveying component, wherein the first conveying component is used to convey the glass upper material;

[0011] The heating section comprises a heating component, a second conveying component and a first detection component, wherein the second conveying component is used to receive the glass conveyed by the first conveying component, and the heating component is used to heat the glass on the second conveying component; the first detection component is used to detect the glass on the second conveying component to send a first detection signal;

[0012] The wind grid section includes an air cooling component, a third conveying component and a second detection component, wherein the third conveying component is used to receive the glass conveyed by the second conveying component, and the air cooling component is used to air cool the glass on the third conveying component; the second detection component is used to detect the glass on the third conveying component to send a second detection signal;

[0013] The lower section includes a fourth conveying component, and the fourth conveying component is used to receive the glass conveyed by the third conveying component.

[0014] In summary, the utility model has the following technical effects:

[0015] 1. The entire glass tempering production line can be fully automated. The glass can be inspected through the detection components of each section, and the parameters of each section can be adjusted, which is faster and more reliable than manual adjustment. The upper and lower pieces can automatically detect glass defects and automatically remove unqualified products without manual inspection, saving labor costs.

[0016] 2. The heating section detects the glass on the second conveying assembly with the first detection component, and transmits the detected glass temperature to the controller of the equipment. By comparing the temperature signal with the heating standard temperature of the glass production system, the heating temperature can be adjusted to reduce the deformation caused by uneven heating in the glass furnace. At the same time, since the glass may also crack or break during the heating process, the first detection component can also be used to perform surface detection on the glass on the second conveying assembly, so that cracks or breaks on the glass surface can be prompted to reduce the breakage of the glass during the heating process.

[0017] 3. Since the wind grid section is equipped with a second detection component, the surface temperature of the glass can be detected through the second detection component, and the detected glass temperature is transmitted to the controller of the equipment, and the glass surface temperature is compared with the actual production cooling temperature, so as to adjust the wind grid section wind pressure, air volume and other related parameters in real time to achieve the uniformity and consistency of the glass temperature in the grid. When the glass temperature reaches the calibration value, the wind grid automatically switches from the quenching state to the cooling state, and the operating frequency of the large fan is reduced in time, achieving the beneficial effect of energy saving and consumption reduction.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] See also Figure 1-Figure 5 The utility model discloses a glass tempering production equipment, including an upper segment 10, a heating segment 20, a wind grid segment 30 and a lower segment 40. The upper segment 10 includes a first conveying component 11, and the first conveying component 11 is used to convey glass to perform glass loading.

[0028] The heating section 20 includes a heating component, a second conveying component 21 and a first detection component 22. The second conveying component 21 can receive the glass conveyed by the first conveying component 11, and the heating component of the heating section 20 can heat the glass on the second conveying component 21. The first detection component 22 can detect the glass on the second conveying component 21 to send a first detection signal. Specifically, the first detection component 22 can detect the surface temperature of the glass, and the first detection signal at this time is a temperature signal. In addition, the first detection component 22 can also detect cracks or breakages on the surface of the glass, and the first detection signal at this time is a glass defect signal.

[0029] In addition, the wind grid section 30 includes an air cooling component, a third conveying component 32 and a second detection component 33. The glass heated by the heating component in the heating section 20 can be conveyed to the wind grid section 30 through the second conveying component 21, and then the third conveying component 32 can receive the glass conveyed by the second conveying component 21, and the air cooling component can air cool the glass on the third conveying component 32. The second detection component 33 can detect the surface temperature of the glass, and the second detection signal at this time is a temperature signal. In addition, the second detection component 33 can also detect cracks or breakages on the surface of the glass, and the second detection signal is a glass defect signal.

[0030] The lower segment 40 includes a fourth conveying assembly 41 . After the glass in the wind grid segment 30 is air-cooled, it can be conveyed to the lower segment 40 by the third conveying assembly 32 , received by the fourth conveying assembly 41 , and conveyed to the lower material by the fourth conveying assembly 41 .

[0031] On the basis of the above structure, when the glass tempering production equipment of the utility model is used, during glass tempering production, the glass can be placed on the first conveying component 11 of the upper segment 10, and the glass is conveyed to the heating segment 20 by the first conveying component 11, and the glass is conveyed by the second conveying component 21 of the heating segment 20, and then the heating component in the heating segment 20 can heat the glass on the second conveying component 21, and the heated glass can be conveyed to the wind grid segment 30 through the second conveying component 21, and after the third conveying component 32 of the wind grid segment 30 receives the heated glass, the third conveying component 32 conveys the heated glass from the heating segment 20 to the wind grid segment 30, and the wind cooling component of the wind grid segment 30 is used to realize glass tempering, and the third conveying component 32 conveys the glass to the lower segment 40, and the fourth conveying component 41 of the lower segment 40 receives the glass for unloading.

[0032] In this embodiment, since the first detection component 22 is provided in the heating section 20, the first detection component 22 detects the glass on the second conveying component 21, and the detected glass temperature is transmitted to the controller of the device. By comparing the temperature signal with the heating standard temperature of the glass production system, the heating temperature can be adjusted, thereby reducing the deformation caused by uneven heating in the glass furnace. At the same time, since the glass may also have heating cracks or breakage during the heating process, the first detection component 22 can also be used to perform surface detection on the glass on the second conveying component 21, so that cracks or breakages on the glass surface can be prompted to reduce the breakage of the glass during the heating process.

[0033] Similarly, since the wind grid section 30 is provided with a second detection component 33, the surface temperature of the glass can be detected by the second detection component 33, and the detected glass temperature is transmitted to the controller of the device, and the glass surface temperature is compared with the actual production cooling temperature, so as to adjust the wind pressure, air volume and other related parameters of the wind grid section 30 in real time to achieve the uniformity and consistency of the glass temperature in the grid. When the glass temperature reaches the calibration value, the wind grid automatically switches from the quenching state to the cooling state, and the operating frequency of the large fan is timely reduced to achieve the beneficial effect of energy saving and consumption reduction.

[0034] Of course, the first detection component 22 and the second detection component 33 can be selected as multiple cameras in the prior art, and multiple cameras are arranged in the conveying direction of the second conveying component 21 and the third conveying component 32. When the glass is conveyed, multiple cameras can capture the surface temperature of the glass. For example, the camera uses an infrared camera, and the infrared camera captures the infrared image of the glass surface, and determines the temperature based on the infrared image. At the same time, the camera can also capture the glass surface, and the glass detection can be achieved by comparing the image with the standard image of glass production.

[0035] It should be noted that in this embodiment, the technical content to be protected is to set the first detection component 22 and the second detection component 33 on the production equipment to detect the temperature, surface defects and size of the glass. The specific way to achieve the detection can be achieved by adopting the camera, temperature detector and other structures in the existing technology. The detection process and principle as well as the comparison principle are all existing technologies and do not belong to the technical content to be protected in this application.

[0036] Furthermore, in this embodiment, the first detection component 22 can be installed above the second conveying component 21, so that the first detection component 22 can detect the glass temperature or glass defects above the glass. The first detection component 22 can also be set below the second conveying component 21, so that the first detection component 22 can detect the glass temperature or glass defects below the glass.

[0037] The first detection component 22 may also be provided above and below the second conveying component 21, so that the upper and lower surface temperature or defect detection of the glass can be performed above and below the glass at the same time, so that the detection result is more accurate.

[0038] Based on the structure that the first detection component 22 includes multiple cameras, if the second conveying component 21 is formed by multiple conveying rollers, the multiple cameras can be distributed in the interval between two adjacent conveying rollers to reduce the detection blind area.

[0039] In this embodiment, a first detection component 22 can be provided at the starting end and the end of the second conveying component 21. In this way, the glass entering the heating section 20 and the outputting position of the heating section 20 can be positioned by the first detection component 22 at the starting end and the end of the second conveying component 21. By positioning the position of the glass, the start and stop of the heating component of the heating section 20 can be adjusted in time. At the same time, the rear wind grid section 30 can start the air cooling component in time according to the glass position of the front heating section 20, thereby improving the action continuity of the heating section 20 and the wind grid section 30.

[0040] Furthermore, since the temperature in the heating section 20 is generally high, the first detection component 22 installed in the heating section 20 is easily affected by the heating temperature, and the first detection component 22 is easily damaged in a high-temperature environment. Therefore, a cooling protection component 23 can be provided on the outside of the first detection component 22, and the cooling protection component 23 is used to cool the first detection component 22. Specifically, the cooling protection component 23 can be provided by providing a cooling cover on the outside of the first detection component 22, and a cooling cavity is provided inside the cooling cover. The cooling cavity can be filled with supercooled air or coolant. The cooling cover is provided on the outside of the first detection component 22 so that the first detection component 22 is not affected by the high heat of the heating section 20, thereby increasing the service life of the first detection component 22.

[0041] Of course, the cooling protection component 23 can also be provided with a plurality of groups of air nozzles outside the first detection component 22, so that the plurality of groups of air nozzles can be used to concentrate cooling air to cool the first detection component 22.

[0042] In short, the cooling protection component is an air cooling component or a water cooling component. That is, the cooling protection component 23 can be an air cooling or water cooling structure, as long as it can achieve cooling and heat dissipation of the first detection component 22.

[0043] Similarly, the second detection component 33 can also be installed above the third conveying component 32, so that the second detection component 33 can detect the glass temperature or glass defects above the glass. The second detection component 33 can also be set below the third conveying component 32, so that the second detection component 33 can detect the glass temperature or glass defects below the glass.

[0044] The second detection component 33 may also be provided above and below the third conveying component 32, so that the upper and lower surface temperature detection or defect detection of the glass can be performed above and below the glass at the same time, so that the detection result is more accurate.

[0045] Furthermore, based on the structure that the second detection component 33 includes multiple cameras, if the second conveying component 21 is formed by multiple conveying rollers, the multiple cameras can be distributed in the interval between two adjacent conveying rollers to reduce the detection blind area.

[0046] Furthermore, a second detection component 33 can be provided at the starting end and the end of the third conveying component 32, so that the glass entering the wind grid section 30 and the glass outputting the wind grid section 30 can be positioned by the second detection component 33 at the starting end and the end of the second conveying component 21. By positioning the position of the glass, the wind grid section 30 can start the air cooling component in time according to the surface temperature of the glass entering the wind grid section 30 and the position of the glass, thereby improving the air cooling efficiency and effect.

[0047] Furthermore, the wind grid section 30 is provided with a plurality of wind knives 31, which can form a wind cooling component of the wind grid section 30, and the plurality of wind knives 31 are spaced and distributed above the conveying direction of the third conveying component 32; a second detection component 33 is provided between two adjacent wind knives 31. By blowing air with the wind knives 31, the surface of the glass can be quenched, and by quenching with a plurality of wind knives 31, the cooling effect is uniform, and the quality of glass tempering is better.

[0048] Due to the presence of multiple wind knives 31 and the short blowing distance, the second detection component 33 is preferably a plurality of groups of line scanning cameras. When the glass reciprocates in the grid, each group of line scanning cameras respectively collects the surface image of the glass in each area, and optimizes and adjusts the wind grid blowing distance, wind pressure, air volume and other parameters.

[0049] Furthermore, the upper segment 10 also includes a third detection component 12, which is used to detect glass on the first conveying component 11 and send a third detection signal; the lower segment 40 also includes a fourth detection component 42, which is used to detect glass on the fourth conveying component 41 and send a fourth detection signal.

[0050] Specifically, the glass conveyed on the first conveying component 11 can be inspected by the third inspection component 12 provided on the upper segment 10. The upper segment 10 is provided with multiple groups of single or multiple groups of cameras for collecting glass information to form the third inspection component 12. The camera shoots the glass to collect the glass image, and compares the glass image with the type, specification, and size of the glass built into the controller of the device, so as to adaptively adjust the heating temperature and cooling temperature of the heating section 20 and the wind grid section 30 according to the type, specification, and size of the loaded glass. In addition, the camera of the third inspection component 12 can also be used to collect whether the glass has defects such as cracks, and unqualified glass can be replaced in time.

[0051] Similarly, a fourth inspection component 42 can be set in the lower segment 40, and a single group or multiple groups of cameras can be set above or below or above the fourth conveying component 41 to form a fourth inspection component 42. The camera photographs the glass to collect the glass image, and the bow, waveform, pitting, etc. of the glass are inspected through the glass image and the controller of the equipment. The defective products can be automatically grabbed by the robot and placed in the defective product placement area.

[0052] Of course, based on the structure that the upper segment 10 has the third detection component 12, a plurality of first lighting lamps 13 can also be arranged under the first conveying component 11. The plurality of first lighting lamps 13 can be arranged at intervals in the conveying direction of the glass. When the third detection component 12 performs detection, the plurality of first lighting lamps 13 can be illuminated to assist the detection of the third detection component 12, so that the detection field of view is brighter.

[0053] It should be noted that, since the third detection component 12 is mainly used to detect the size or defects of the glass on the first conveying component 11, the size and defects of the glass can only be clearly detected when the lighting brightness is sufficient.

[0054] Similarly, on the basis of the structure that the lower segment 40 has the fourth detection component 42, a plurality of second lighting lamps 43 can be arranged below the fourth conveying component 41. The plurality of second lighting lamps 43 can be arranged at intervals in the conveying direction of the glass. When the fourth detection component 42 performs the detection action, the plurality of second lighting lamps 43 can illuminate to assist the detection of the fourth detection component 42, making the detection field brighter. Of course, since the fourth detection component 42 is mainly used to detect the size or defects of the glass on the fourth conveying component 41, the size and defects of the glass can only be clearly detected when the lighting brightness is sufficient.

[0055] In addition, in order to facilitate the first lighting lamp 13 and the second lighting lamp 43, the first lighting lamp 13 and the second lighting lamp 43 can be installed with the mounting pillar or the bracket structure. And on the basis of the structure that the first conveying assembly 11 and the fourth conveying assembly 41 use multiple conveying rollers, the first lighting lamp 13 and the second lighting lamp 43 can be installed between two adjacent conveying rollers through the mounting pillar or the bracket, so as to avoid the conveying rollers, prevent the lighting blind area, and make the lighting effect more uniform.

[0056] Of course, if the first conveying component 11 and the fourth conveying component 41 use conveying belts or other conveying structures, the first lighting lamp 13 and the second lighting lamp 43 can be distributed above the first conveying component 11 and the fourth conveying component 41 to provide auxiliary lighting above, which can also reduce the lighting blind spot.

[0057] Furthermore, the third detection component 12 and the fourth detection component 42 can be implemented by detection cameras or cameras in the prior art. When installing, the camera can be assembled by installing a support or a bracket. The support or bracket used to assist the camera assembly can be adjusted to a suitable distance according to the glass specifications and arrangement. For example, the support or bracket structure is evenly spaced to achieve the distribution of multiple detection cameras or cameras above the first conveying component 11 and the fourth conveying component 41. In this way, the spacing can be achieved at each position of glass loading or unloading to ensure the detection effect. For another example, a retractable mounting support or bracket structure (such as a telescopic rod) can be used to achieve the distribution of multiple detection cameras or cameras above the conveying component and the fourth conveying component 41 at an equal distance. The telescopic mounting support or bracket structure can be retracted in the height direction, and the distance between the multiple detection cameras or cameras and the glass can be adjusted according to the glass specifications and thickness adaptability.

[0058] It should be noted that the installation method of the third detection component 12 and the fourth detection component 42 can be selected according to actual production needs.

[0059] Furthermore, the upper segment 10, the heating segment 20, the wind grid segment 30 and the lower segment 40 all include a positioning detection component 50, and the positioning detection component 50 is used to detect the position of the glass to send a position signal.

[0060] A positioning detection component 50 is provided in each section of the glass tempering equipment. The positioning detection component 50 can be formed by a camera or a plurality of groups of laser emitters. The position of the glass can be detected by the positioning detection components 50 in different sections, and the position of the glass can be compared with the controller of the production equipment, so as to realize the linkage of various components in different production sections, provide the operation continuity of the production equipment, and realize the effect of uniform heating and uniform cooling of the glass in the furnace and the grid.

[0061] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
