Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection equipment, more specifically, the present application relates to a kind of detection equipment based on building construction for building material processing. BACKGROUND

[0002] Glass curtain wall is a new type of building envelope structure composed of metal frame and glass panel, which has good lighting performance and can provide sufficient natural light for indoor, creating a bright and comfortable indoor environment. It is a commonly used building material in current construction, and glass curtain wall needs to have certain corrosion resistance to resist acid rain, ultraviolet radiation and other erosion for a long time in complex natural environment, so as to prolong its service life. Therefore, in order to strictly control the quality of glass curtain wall and avoid the use of unqualified products to affect the construction cost, glass curtain wall needs to be detected for corrosion resistance and optical performance before leaving the factory.

[0003] In the prior art, when batch glass curtain wall is processed and optical performance is detected, one of them will be randomly selected as a workpiece to be detected. In order to more closely simulate the use environment of glass curtain wall in rainy days in actual environment, the workpiece is continuously sprayed with corrosive liquid reagent, and then the corrosion condition of glass surface is continuously detected by using visual recognition instrument to improve the detection accuracy. In addition, in order to effectively reduce the attenuation, scattering and interference of light in the propagation process between glass and collection end, so as to enhance the intensity and stability of signal, and more accurately capture the slight change of light after passing through glass, the collection end of visual recognition instrument needs to be close to glass.

[0004] However, since the collection end of visual recognition instrument is close to glass, after the reagent is sprayed on the surface of the workpiece to be detected, part of the reagent will splash on the collection end of visual recognition instrument.

[0031] The following detailed description of the application is made in conjunction with the accompanying drawings, it is necessary to point out here that the following detailed description is only used to further illustrate the application, and cannot be understood as limiting the scope of protection of the application, and those skilled in the art can make some non-essential improvements and adjustments to the application according to the above application content.

[0033] The detection box 1 is also provided with a light emitting mechanism 3 and a detection mechanism 4, the light emitting mechanism 3 comprises a light emitter 32, the light emitter 32 is located on one side of the workpiece 5, the detection mechanism 4 comprises a visual recognition instrument 41, the visual recognition instrument 41 is located on the other side of the workpiece 5, the light emitter 32 is used for emitting light to the test area, so that the light passes through the workpiece 5, and the collection end of the visual recognition instrument 41 is used for detecting the light passing through the workpiece 5;

[0034] The detection mechanism 4 further comprises a shielding cover 42 and a transparent glass 43, the shielding cover 42 is fixedly arranged on the visual recognition instrument 41, the collection end of the visual recognition instrument 41 is located in the shielding cover 42, the transparent glass 43 is located between the collection end of the visual recognition instrument 41 and the shielding cover 42, and the transparent glass 43 rotates in the shielding cover 42 so that the front side of the collection end of the visual recognition instrument 41 is always in a dry state.

[0035] It should be noted that the detection box 1 is fixedly provided with a linear driver four, the output end of the linear driver four is fixedly provided with a rotating driver three, the output end of the rotating driver three is fixedly provided with an auxiliary seat, and the visual recognition instrument 41 is fixedly arranged on the auxiliary seat. The linear driver four is arranged as a linear motor, the rotating driver four is arranged as a motor, the movement of the output end of the linear driver four is used to drive the vertical movement of the visual recognition instrument 41, and the rotation of the output end of the rotating driver three is used to adjust the angle between the collection end of the visual recognition instrument 41 and the workpiece 5.

[0036] It should be further noted that the workpiece 5 is a glass curtain wall to be detected selected by random sampling. In order to effectively reflect infrared rays and reduce indoor heat transfer, the effect of heat insulation and heat preservation is realized, that is, outdoor heat can be blocked from entering the indoor, and indoor heat can be prevented from being lost, so that the purpose of energy saving is achieved. The glass curtain wall is coated with a layer of low-emission film. The glass curtain wall coated with a layer of low-emission film can obviously improve the use effect when applied as a new material in buildings. The low-emission film includes but is not limited to the use of Low-E film. The Low-E film mainly includes a metal functional layer, a dielectric layer, and a protective layer. The protective layer is located at the outermost layer of the Low-E film and is mainly used to protect the functional layer in the middle, prevent it from being oxidized, corroded or mechanically damaged, and prolong the service life of the film layer. Common protective layer materials include nitrides, oxides, etc. Therefore, the use of optical detection equipment to detect the performance of the workpiece 5 can also be understood as detecting the functional layer of the Low-E film. The reagent is used to simulate corrosive substances that may be encountered in the actual environment. The reagent is set as a liquid, and the reagent includes but is not limited to acid solution, alkali solution, salt solution, and organic solvent, etc. The reagent can also be selected to be higher than the corrosive substances that may be encountered in the actual environment to detect the corrosion resistance limit of the arc-shaped coated glass. The transparent glass 43 has good optical performance, and the transparent glass surface is provided with a fluorocarbon resin layer, which can improve the corrosion resistance of the optical glass.

[0037] Further, the light beam emitted by the light emitter 32 is vertically arranged between the workpiece 5, and the visual recognition instrument 41 includes an optical camera, which can record the macro changes on the surface of the workpiece 5, such as color, gloss, transparency, etc. Changes at different time points can be compared to evaluate the corrosion resistance. The collection end of the visual recognition instrument 41 can vertically collect the light beam emitted by the light emitter 32 through the workpiece 5, and the visual recognition instrument 41 can obtain high-quality images, avoiding problems such as image distortion, overexposure or overdarkness, and image edge blur. The detection mechanism 4 also includes a light transmittance detector, which can detect the light transmittance of the workpiece 5 by vertically collecting the light beam emitted by the light emitter 32 through the workpiece 5.

[0038] In order to facilitate the recycling of the reagent sprayed towards the workpiece 5, improve the utilization efficiency of resources, specifically, two baffles 11 are fixedly arranged in the detection box 1, and a storage area is formed between the two baffles 11. A pump 12 is fixedly arranged in the detection box 1, the liquid inlet end of the pump 12 extends to the bottom of the storage area, the liquid outlet end of the pump 12 is fixedly communicated with a flow guide pipe 13, and a spray head is fixedly arranged on the flow guide pipe 13. The flow guide pipe 13 sprays the reagent towards the workpiece 5 through the spray head, and the reagent falls into the storage area. The reagent in the storage area is conveyed into the flow guide pipe 13 through the air inlet end of the pump 12, and the reagent is recycled. The spray head on the flow guide pipe 13 is provided with a plurality of spray heads, and the incident angle between the reagent sprayed by the spray head and the workpiece 5 is set to 30°, 45° and 60°. An electromagnetic valve is further arranged between the spray head and the flow guide pipe 13, and the opening and closing of the electromagnetic valve can adjust the spray angle between the reagent and the workpiece 5. The contact angle between the reagent and the workpiece 5 is different, and the kinetic energy loss, normal force and tangential force between the reagent and the workpiece 5 are different, which is beneficial to adjust the detection of the workpiece 5 according to the use requirement.

[0039] It should be further pointed out that the transparent glass 43 is circular, and when the transparent glass 43 rotates around the circumference, the transparent glass 43 can always shield the collection end of the visual identification instrument 41, so as to avoid the reagent from splashing to the collection end of the visual identification instrument 41. The continuous detection of the visual identification instrument 41 on the workpiece 5 is divided into two kinds, one is uninterrupted continuous detection, and the other is to detect one side every two minutes, so as to realize complete detection. The detection mode can be selected according to the use requirement, and the detection mode of detecting one side every two minutes is adopted in the present application.

[0040] The implementation scene is as follows: the workpiece 5 is vertically fixed in the detection box 1, the reagent is placed in the storage area, and then the pump 12 is started. The pump 12 sprays the reagent in the storage area on the workpiece 5 through the flow guide pipe 13, realizes the use environment of the glass curtain wall in the rain in the actual environment, then the output end of the light emitter 32 emits a light beam towards the workpiece 5, and the collection end of the visual recognition instrument 41 receives the light beam passing through the workpiece 5 to continuously detect the corrosion condition of the workpiece 5. The collection end of the visual recognition instrument is close to the glass to improve the detection accuracy. After the reagent is sprayed on the surface of the workpiece to be detected, part of the reagent will splash to the collection end of the visual recognition instrument. Since the transparent glass 43 is arranged, the transparent glass 43 can block the splashing reagent from splashing to the collection end of the visual recognition instrument 41. The corrosion condition of one side of the workpiece 5 is detected every two minutes, the transparent glass 43 is driven to rotate before the visual recognition instrument 41 detects, the rotation of the transparent glass 43 can adjust the area between the transparent glass 43 and the collection end of the visual recognition instrument 41, so that the dry area on the transparent glass 43 is repositioned in front of the collection end of the visual recognition instrument 41, thereby avoiding the splashing reagent in front of the collection end of the visual recognition instrument 41 when the collection end of the visual recognition instrument 41 collects the corrosion condition of the surface of the workpiece 5, and avoiding the water droplets in the reagent from forming a small convex lens to produce scattering and refraction.

[0041] Compared with the prior art, by arranging the detection mechanism 4, the transparent glass 43 rotatable is arranged in front of the collection end of the visual recognition instrument 41, so that when the collection end of the visual recognition instrument 41 collects the corrosion condition of the surface of the workpiece 5, there is no splashing reagent in front of the collection end of the visual recognition instrument 41, the water droplets will not form a small convex lens on the collection end, the light passing through the glass will not be scattered and refracted, the light cannot reach the collection end along the preset light path, the light signal received by the collection end becomes chaotic and disordered, the signal strength and stability are improved, the interference of the visual recognition instrument on the corrosion condition of the glass surface is eliminated, the accurate monitoring is improved, and the accuracy and reliability of the optical performance detection of the glass curtain wall are improved.

[0042] The accompanying drawings are referred to in the description of the specification Figures 5 to 7In order to further improve the simulation of the workpiece 5 in the actual use environment, some particle impurities are usually added in the reagent to simulate the particle impurities in the environment, and the particle impurities can also improve the damage to the workpiece 5 and thus shorten the required time of the experiment. If the reagent contains impurity particles, the particle impurities attached to the transparent glass 43 will also affect the detection accuracy. Therefore, it is necessary to ensure that the transparent glass 43 part located in front of the visual identification instrument 41 is in a dry state and there is no particle impurity shielding. Therefore, it is necessary to clean the reagent adhered to the surface of the transparent glass 43. Specifically, the detection mechanism 4 further comprises two groups of moisture absorption rollers 45, both of which are rotationally arranged in the shielding cover 42. The outer side of the moisture absorption roller 45 is in contact with the side of the transparent glass 43 close to the workpiece 5. The shielding cover 42 is fixedly provided with a gas blowing cover 46. The moisture absorption roller 45 is used to absorb the reagent splashed to the surface of the transparent glass 43. The shielding cover 42 is fixedly provided with a gas blowing cover 46. The exhaust end of the gas blowing cover 46 is arranged towards the moisture absorption roller 45. The gas blown by the gas blowing cover 46 is used to blow away the reagent and particle impurities on the surface of the transparent glass 43. The gas blown by the gas blowing cover 46 is also used to dry the moisture absorption roller 45. The visual identification instrument 41 is fixedly provided with a rotary driver one 431. The output end of the rotary driver one 431 is fixedly arranged with the transparent glass 43. The shielding cover 42 is fixedly provided with a rotary driver two 44. The output end of the rotary driver two 44 is fixedly arranged with the moisture absorption roller 45.

[0043] It should be noted that the rotary driver two 44 is arranged as a motor. The output end of the motor is fixedly arranged with the driving shaft of the moisture absorption roller 45. The rotary driver one 431 is arranged as a motor. The output end of the motor is fixedly arranged with the transparent glass 43.

[0044] It should be further noted that the moisture absorption roller 45 is arranged as a moisture absorption sponge. The heating wire is fixedly arranged in the driving shaft of the moisture absorption roller 45. The temperature of the moisture absorption roller 45 is increased by the heating wire, which can accelerate the drying speed of the moisture absorption roller 45 to absorb the reagent. A groove is formed in the driving shaft. The heating wire is fixedly arranged in the groove by using special high-temperature glue, ceramic fixing parts and the like. The heating wire is fixedly arranged in the groove to prevent displacement and shaking due to the centrifugal force of rotation. At the same time, the heating wire is insulated by using insulation materials resistant to high temperature and wear, such as ceramic insulation sleeves and mica sheets, to avoid electric leakage and short circuit. The power is introduced through a slip ring. The internal annular conductive track is in contact with the external static brush to realize stable transmission of electric current inside and outside the rotating shaft. A heat dissipation channel is designed in the rotating shaft to circulate hot air or fluid to carry away excess heat. A temperature sensor is installed to monitor the temperature and feed back to the temperature controller to automatically adjust the power of the heating wire, so that the rotating shaft works at a suitable temperature. The arrangement of the electric heating wire is mature existing technology and will not be described in detail here.

[0045] Further, the air blowing cover 46 is fixedly connected with an air pump. After the air pump is started, the air pump exhaust end sprays gas through the air blowing cover 46, and the gas sprayed by the air blowing cover 46 is sprayed towards the surface of the transparent glass 43 and the moisture absorption roller 45.

[0046] In the embodiment, when the collection end of the visual recognition instrument 41 continuously collects the corrosion condition of the surface of the workpiece 5, the pump is started, the pump sprays gas towards the transparent glass 43 and the moisture absorption roller 45 through the air blowing cover 46, the rotating driver one 431 is started, the rotation of the output end of the rotating driver one 431 can drive the transparent glass 43 to rotate, the rotating driver two 44 is started, the rotation of the output end of the rotating driver two 44 drives the moisture absorption roller 45 to rotate, after the reagent falls on the transparent glass 43, because the reagent contains particle impurities, the gas sprayed by the air blowing cover 46 can blow away the particle impurities attached to the surface of the transparent glass 43, then the reagent attached to the surface of the transparent glass 43 contacts the surface of the moisture absorption roller 45 with the rotation of the transparent glass 43, the moisture absorption roller 45 absorbs the reagent on the surface of the transparent glass 43, and the surface of the transparent glass 43 is dried, at the same time, the heating wire can increase the temperature of the moisture absorption roller 45 to accelerate the drying of the moisture absorption roller 45, the gas sprayed by the air blowing cover 46 can further accelerate the drying of the moisture absorption roller 45, and the front side of the collection end of the visual recognition instrument 41 can be ensured to be in a state at all times with the rotation of the transparent glass 43, so as to improve the detection accuracy. The gas sprayed by the air blowing cover 46 can not only blow away the particle impurities attached to the surface of the transparent glass 43, but also avoid that the friction between the moisture absorption roller 45 and the surface of the transparent glass 43 causes scratches on the surface of the transparent glass 43 due to the existence of the particle impurities, and can accelerate the drying of the moisture absorption roller 45.

[0047] Referring to the drawings Figure 8 With Figure 9 In order to accelerate the formation and expansion of the surface damage of the workpiece 5, make the potential defects appear faster, thereby shorten the detection time and improve the detection efficiency, at the same time, more truly simulate the larger impact that the workpiece 5 may bear under actual working conditions, help more accurately evaluate the wear resistance and corrosion resistance of the workpiece 5, the impact force of the spray head spraying the reagent towards the workpiece 5 is increased, the impact force of the reagent spraying is increased, which can more efficiently cause the abrasion and corrosion of the glass, the increase of the impact force of the reagent spraying can accelerate the splashing of the reagent, in order to improve the detection accuracy, specifically, two winding rollers 47 and a guide roller 48 are rotationally arranged in the shielding cover 42, the same moisture absorption layer 49 is wound and fixedly arranged on the two winding rollers 47, the guide roller 48 is in transmission with the moisture absorption layer 49, and the moisture absorption layer 49 is used for absorbing the reagent splashed to the surface of the transparent glass 43 after contacting the transparent glass 43.

[0048] It should be noted that the moisture absorption layer 49 includes but is not limited to being provided as a synthetic fiber, and the natural fiber has good moisture absorption and air permeability. The motor is fixedly arranged on the shielding cover 42, and the output end of the motor is fixedly arranged with the winding roller 47. The two winding rollers 47 are fixedly provided with pulleys, and the two pulleys are driven by the same belt, that is, the rotation of the output end of the motor can drive the two winding rollers 47 to rotate synchronously, and the winding and unwinding of the moisture absorption layer 49 on the two winding rollers 47 is completed.

[0049] It should also be noted that, referring to Figure 8 , the transparent glass 43 rotates counterclockwise, and the moisture absorption roller 45 is provided as one. The shielding cover 42 can still use two moisture absorption rollers 45 according to the use requirement. The gas blown out by the air blowing cover 46 can remove the large droplet reagent and particle impurities attached to the surface of the transparent glass 43. Since there may be more reagent on the surface of the transparent glass 43, the winding and unwinding of the moisture absorption layer 49 by the two winding rollers 47 enables the different positions of the moisture absorption layer 49 to contact the surface of the transparent glass 43 to adsorb the reagent, so that the transparent glass 43 located in front of the visual identification instrument 41 is always in a dry state, thereby improving the detection accuracy.

[0050] Referring to the drawings attached Figures 1 to 4 in the specification, in order to facilitate positioning of the workpiece to be detected, specifically, the positioning mechanism 2 further includes a linear actuator one 21 fixedly arranged in the detection box 1.

The clamping part 23 includes a mounting shell 231 fixedly arranged on the connecting seat 22, and a linear actuator two 232 fixedly arranged on the mounting shell 231. The output end of the linear actuator two 232 is fixedly provided with a pushing seat 234, and the pushing seat 234 is slidingly arranged in the mounting shell 231. The mounting shell 231 slidingly arranged therein is provided with a positioning claw 233, and the positioning claw 233 is slidingly arranged with the pushing seat 234.

[0051] It should be noted that the linear actuator two 232 is provided as an air cylinder, and the output end of the air cylinder is fixedly arranged with the pushing seat 234. As Figure 4 indicated, the pushing seat 234 is provided as a wedge, and the inclined surface of the pushing seat 234 is fixedly provided with a guide seat. The positioning claw 233 is provided with a guide groove, and when the pushing seat 234 slides in the mounting shell 231, the two positioning claws 233 are synchronously close to or away from the length direction of the mounting shell 231. Referring to Figure 2 , the supporting seat 24 includes a fixed box, and two limiting seats are slidingly arranged in the fixed box. Two threaded rods are threadedly connected to the fixed box, and the ends of the threaded rods are rotatably arranged with the supporting seat 24. Rotating the two threaded rods can adjust the distance between the two limiting seats.

[0052] It also needs to be explained that the workpiece 5 is placed on the support seat 24, and then the threaded rod is rotated to adjust the distance between the two limiting seats, so that the limiting seat tightly abuts the two sides of the workpiece 5, and then the linear actuator one 21 is started to adjust the height of the positioning claw 233, and the linear actuator two 232 is started to drive the two positioning claws 233 to approach each other to clamp the workpiece 5, and the workpiece 5 is vertically positioned through the cooperation of the positioning claw 233 and the limiting seat, so that the workpiece 5 is in a stable vertical state, and then the optical performance and corrosion resistance are detected.

[0053] Referring to the description attached Figure 2 In order to facilitate the adjustment of the detection position of the workpiece 5 according to the use requirement, specifically, the light emitting mechanism 3 further comprises a linear actuator three 31, which is fixedly arranged on the inner wall of the detection box 1, and the light emitter 32 is fixedly arranged on the output end of the linear actuator three 31, and the output end of the linear actuator three 31 is used to drive the light emitter 32 to move vertically.
