DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1-Figure 2 As shown, a quality inspection equipment for real stone paint production includes a wall template 1 and a real stone paint coating template 2 arranged on one side of the wall template 1, a spray mechanism 3 is installed on the upper end of the wall template 1, the nozzle of the spray mechanism 3 is perpendicular to the outer surface of the real stone paint coating template 2, the input end of the spray mechanism 3 is connected to a water pump, and the water pump draws water from a storage tank and sprays it onto the surface of the real stone paint coating template 2, and the water in the storage tank is formulated to be similar to rainwater, and the sprayed water can also be blown by an auxiliary fan to maximize the simulation of daily raining and improve the detection accuracy.

[0033] A support frame 11 is installed at the lower end of the wall formwork 1, and an inclined bracket 12 is installed on one end of the support frame 11. The end of the inclined bracket 12 away from the support frame 11 is connected to the wall formwork 1 by screws. The middle part of the support frame 11 is hollow, which is convenient for the sprayed rainwater and the water flowing down from the real stone paint coating formwork 2 to pass through the middle part of the support frame 11 and be discharged from the circulating underground system.

[0034] like Figure 1-Figure 3 As shown, a horizontal driving mechanism 4 is arranged in the middle of the support frame 11, and a vertical driving mechanism 5 is installed on the horizontal driving mechanism 4. The horizontal driving mechanism 4 includes a support rod 41 and a driving member 42 installed at one end of the support rod 41, and a screw rod 43 is installed at the driving end of the driving member 42. Both ends of the screw rod 43 are movably connected with the inner side of the support rod 41, and the screw rod 43 is located in a through groove opened in the middle of the support rod 41, and the through groove facilitates rainwater to flow out of the support rod 41. The driving member 42 can drive the screw rod 43 to rotate, and the screw rod 43 matches the lower end thread of the vertical driving mechanism 5. The screw rod 43 can drive the vertical driving mechanism 5 to reciprocate along the direction of the support rod 41, so as to facilitate the vertical driving mechanism 5 to approach or move away from the real stone paint coating template 2.

[0035] The vertical driving mechanism 5 includes a supporting shell 51 and a moving block 52 installed at the lower end of the supporting shell 51. The moving block 52 is threadedly matched with the screw rod 1 43. A driving member 2 53 is installed at the upper end of the supporting shell 51. The driving member 1 42 and the driving member 2 53 are preferably servo motors. A screw rod 2 54 is installed at the driving end of the driving member 2 53. The outer side of the screw rod 2 54 is threadedly installed with a driving block 1 55 and a driving block 2 56. The driving member 2 53 drives the screw rod 2 54 to rotate, and the driving block 1 55 and the driving block 2 56 are driven to move up and down.

[0036] like Figure 3-Figure 6 As shown, a light detector 6 is installed on one side of the driving block 55. The light detector 6 includes an auxiliary block 61 and an elastic member 62 installed on the periphery of one side of the auxiliary block 61. The elastic member 62 can be a rubber pad, a spring sheet or an elastic plastic sheet. It not only plays a buffering role when the auxiliary block 61 contacts the real stone paint coating template 2, but also effectively seals the cavity enclosed by the auxiliary block 61 and the real stone paint coating template 2, thereby reducing the influence of the outside world on the detection of the light detector 6.

[0037] Two inner cavities 611 are provided on one side of the auxiliary block 61 close to the elastic member 62. Each inner cavity 611 is provided with an emitting light source 63, a light source receiving sensor 64 and a light focusing plate 65. A plurality of light source receiving sensors 64 are provided. The emitting light source 63 is installed on the inner side of the auxiliary block 61, and the light source receiving sensor 64 is located at the lower end of the emitting light source 63 and is installed on the inner side of the auxiliary block 61, and the light focusing plate 65 is located at the lower end of the emitting light source 63 and is installed on the inner side of the auxiliary block 61;

[0038] Further, such as Figure 5-Figure 6 As shown, the light source receiving sensor 64 is composed of sensor 1 641, sensor 2 642 and sensor 3 643. The light detection point emitted by the light source 63 to the surface of the real stone paint coating template 2 is 0° (equivalent to the manual observation angle) from the perspective of sensor 1 641, 45° from the perspective of sensor 2 642, and 60° from the perspective of sensor 3 643. The light source receiving sensor 64 is an optical sensor such as a photodiode or a spectrometer, which is used to capture light of different wavelengths, i.e., different colors. Specifically, the light detector 6 is driven downward by the driving block 1 55 to perform color difference detection on the real stone paint coating template 2 impacted by rain. After the light source is received by the light source receiving sensor 64, , measure the L, a and b values ​​of each measuring point of the real stone paint coating template 2 from top to bottom, and each measuring point is measured at 0°, 45° and 60° viewing angles respectively, and compare the measured data with the new real stone paint coating to determine the color difference change of the real stone paint coating template 2 after rain erosion, and also compare the data with the real stone paint coating that has been put on the market and has undergone rain erosion testing in the past, and judge whether the real stone paint is qualified by the color difference change, not only through instrument detection to ensure its accuracy, but also through detection at different viewing angles to improve the detection diversity and further improve the detection effect, at the same time, by moving the detection of different real stone paint coating templates 2 washed by rain from top to bottom, the detection diversity is further improved and the detection effect is further improved.

[0039] Furthermore, in order to further ensure the detection accuracy, at least 5 real stone paint coating templates 2 can be tested, and a detection point is determined for each, and the L, a and b values ​​are recorded. The deviation data of the L, a and b values ​​are calculated by the formula, and then further compared with the real data to further improve the detection accuracy;

[0040] The formula for calculating deviation data is:

[0041]

[0042] Among them, x represents the detection point data set, n represents the number of detection data points, and y represents the mean of the detection point data set.

[0043] like Figure 3 , Figure 7-Figure 8 As shown, a simulated destructive component 7 is installed on one side of the driving block 56, and the simulated destructive component 7 includes a connecting block 71 and a rotating block 72 movably connected to the connecting block 71. The rotating block 72 is fixedly connected to the connecting block 71 by a spring 74, and when the elasticity of the spring 74 does not change, the connecting block 71 and the rotating block 72 are on the same horizontal line, and a knocking head 73 is installed on the end of the rotating block 72 away from the connecting block 71. A plurality of blocking rods 512 are installed on the inner side of the supporting shell 51. The blocking rod 512 is composed of a fixed rod and a sleeve rod sleeved on the outer side of the fixed rod. When the screw rod 54 drives the light detector 6 to perform detection, it also drives the driving block 56 to move, so that the simulated destructive component 7 moves downward. In the process of the knocking head 73 moving downward, it is blocked by the set blocking rod 512. The knocking head 73 rotates axially around one end of the connecting block 71. As it continues to move downward, the end of the knocking head 73 passes over the blocking rod 51. 2, the knocking head 73 is reset by the spring 74, and under the reset force, the knocking head 73 quickly knocks the real stone paint coating template 2, causing the surface of the real stone paint coating template 2 to be damaged. By analogy, the real stone paint coating template 2 is also simulated to be knocked from top to bottom. When it is necessary to detect the knocking point, the support shell 51 is separated from the real stone paint coating template 2, and then the screw rod 2 54 is driven in reverse to move the light detector 6 up to the corresponding knocking detection point, and then the support shell 51 is pushed close to the real stone paint coating template 2, and the light detector 6 is used for detection. When the light emitted by the emitting light source 63 is irradiated on the surface of the real stone paint coating template 2, if the surface is smooth and without scratches, the light will be reflected in the same direction and received by the light source sensor 64; if there are scratches on the surface, the edge of the scratch will break the average reflection of the light, causing the light to be scattered, so that the scratch area shows obvious changes in light and dark, completing the knocking detection and determining the durability of the real stone paint.

[0044] like Figure 8-Figure 9As shown, a square groove 1 711 is provided on the inner side of the connecting block 71, and a locking piece 75 is inserted into the inside of the square groove 1 711. The locking piece 75 includes a polygonal rod 751 and a transfer column 752 movably arranged at one end of the polygonal rod 751. The polygonal rod 751 matches the square groove 1 711, and one end of the transfer column 752 is covered with a rolling tube 753. The polygonal rod 751 also passes through the polygonal groove 2 721 provided on the rotating block 72. A plurality of unlocking rods 511 are installed on the inner side of the supporting shell 51. The unlocking rod 511 is composed of a rectangle and triangles at both ends of the rectangle when viewed from the side. The rolling tube 753 corresponds to the unlocking rod 511. A reset spring 754 is also sleeved on the outer side of the polygonal rod 751, and the reset spring 754 is installed in the middle of the polygonal groove 2 721.

[0045] Specifically, before the rotating block 72 contacts the blocking rod 512, one end of the polygonal rod 751 is inserted into the square groove 711, and when the light detector 6 moves downward for detection, the knocking head 73 contacts the real stone paint coating template 2 and scrapes the surface of the real stone paint coating template 2 as it moves, and then the light detector 6 moves upward in the opposite direction for light detection, and then compares it with the qualified real stone paint data to complete the detection of the anti-scratch and adhesion effects of the real stone paint coating;

[0046] When the rolling tube 753 contacts the unlocking rod 511, since the two ends of the unlocking rod 511 are triangular in shape, they will push the rolling tube 753 to move in the opposite direction, and pull the polygonal rod 751 out of the square groove 711, so that the rotating block 72 is restricted from rotating by the blocking rod 512, thereby realizing the knocking and wall scraping simulation detection.

[0047] It should be noted that, in the description of the present application, it should be understood that the terms "length", "thickness", "inside", "outside", "axial", "radial", etc., indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
