[0002] The ash dish is a commonly used instrument for gold testing by fire assay. It is a porous refractory vessel used to absorb lead oxide when blowing lead. There are three commonly used ash dishes: cement ash dish, bone ash-cement ash dish and magnesia ash dish. The magnesia ash dish is an important ash blowing tool used in fire assay. During the ash blowing process, lead is oxidized into lead oxide, which is gradually oxidized from the surface of the molten lead and quickly absorbed by the magnesia ash dish until all the molten lead is oxidized into lead oxide and absorbed. The national standard for gold concentrate (compound gold) requires the use of magnesia (bone ash) ash dishes during the ash blowing process. Cement, magnesia (bone ash) and water are mixed evenly according to the mass ratio and then pressed into shape on an ash dish machine. They are dried in the shade for three months and then used.

[0003] The Chinese invention patent with application number CN202311317789.9 discloses an ash dish machine and an ash dish production method, including a frame, a pressing mechanism, a feeding mechanism, a drying mechanism, a transmission mechanism and a discharging mechanism. The raw materials required for the production and processing of the ash dishes are stirred and mixed evenly in the feeding mechanism, and transmitted to the discharging mechanism through the discharging mechanism. The pressing mechanism and the discharging mechanism cooperate to extrude and lift the ash dishes. Finally, the transmission mechanism transports them to a position that is convenient for manual removal. The ash dishes are produced and processed automatically throughout the process, avoiding manual intervention and avoiding the safety risks of traditional manual operations.

[0004] However, the above-mentioned ash dish machine does not detect the ash dishes when producing them, and is unable to judge the quality of the formed ash dishes, which needs to be improved. Summary of the invention

[0051] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with its embodiments. It should be understood that the specific implementation methods described herein are only used to explain the present invention and do not limit the protection scope of the present invention.

[0054] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0055] Ash dish is a commonly used instrument for gold testing by fire assay. It is a porous refractory vessel used to absorb lead oxide when blowing lead with ash. There are three commonly used ash dishes: cement ash dish, bone ash-cement ash dish and magnesia ash dish. "Chemical Analysis Method of Gold Concentrate - Determination of Gold and Silver Content" is the national standard GB / T7739.1-2007, which is the most frequently used standard in the gold industry and is also an internationally recognized standard. Magnesia ash dish is used in the ash blowing process. Magnesia ash dish is made of magnesia, cement and water in a certain proportion. According to your needs, the ash dish can be made into various sizes and dried in the shade for three months before use.

[0056] The magnesia ash dish is an important ash blowing tool used in fire assaying. During the ash blowing process, lead is oxidized into lead oxide, which gradually oxidizes from the surface of the molten lead and is quickly absorbed by the magnesia ash dish until all the molten lead is oxidized into lead oxide and absorbed. A large amount of lead oxide is absorbed by the ash dish, and the lead oxide discharged into the air is very small, which is conducive to protecting air quality and greatly reducing pollutant emissions.

[0057] Existing ash tray equipment for producing ash trays, such as the Chinese invention patent "A ash tray machine and ash tray production method" with application number CN202311317789.9, the Chinese invention patent "An automatic feeding ash tray machine for producing ash trays and a method for mass production of ash trays" with application number CN201610494793.6, and the Chinese invention patent "A fully automatic and efficient ash tray machine and a method for producing ash trays" with application number CN201810788196.3, all extrude the ash tray raw materials in the forming mold to obtain the formed ash tray, and then take out the formed ash tray for shade drying or drying. There is no defect detection on the formed ash tray, and the ash tray after shade drying or drying is prone to defective products. For this reason, it is necessary to improve the existing ash tray production equipment and production methods to improve the quality of ash tray production.

[0058] In order to solve the problems existing in the existing ash tray production equipment, one embodiment of the present invention provides an ash tray production equipment, such as Figure 3 as well as Figure 4 As shown, it includes a detection mechanism 9, which includes a multi-dimensional data acquisition module, a quality calculation module and a judgment module.

[0059] The method is used to obtain feature data of multiple different dimensions of the ashtray to be detected; the multiple different dimensions here can be understood as different types, and the data features of the multiple different dimensions include but are not limited to the image pixel grayscale value of a certain area of ​​the ashtray to be detected at a certain angle, the contour line shape of a certain area at a certain angle, the voiceprint feature of a certain area and the ultrasonic signal emitted back, and the local and overall image pixel grayscale value and contour line shape at a certain angle.

[0060] The quality calculation module is used to calculate the single quality degree of the ashtray to be detected in each dimension according to the feature data in multiple different dimensions, and calculate the comprehensive quality degree of the ashtray to be detected in multiple different dimensions according to the single quality degree of the ashtray to be detected in each dimension.

[0061] As a preferred technical solution, the specific method for calculating the single quality degree of the ashtray to be detected in each dimension according to the feature data of multiple different dimensions includes: obtaining the type of the ashtray to be detected according to the feature data of multiple different dimensions, obtaining multiple standard feature data of a standard ashtray consistent with the type of the ashtray to be detected and multiple defect feature data of a defective ashtray according to the type of the ashtray to be detected, obtaining the first association weight value between the standard ashtray and the ashtray to be detected in each dimension, calculating the first quality index in each dimension according to the first association weight value, the feature data of the ashtray to be detected and the standard feature data of the standard ashtray, obtaining the second association weight value between the defective ashtray and the ashtray to be detected in each dimension, calculating the second quality index in each dimension according to the second association weight value, the feature data of the ashtray to be detected and the defect feature data of the defective ashtray, and calculating the single quality degree of the ashtray to be detected according to the first quality index and the second quality index.

[0062] The judging module is used to judge whether the ashtray to be inspected is a good product according to the comprehensive quality degree.

[0063] Specifically, a quality threshold is preset first, and then the comprehensive quality is compared with the quality threshold. If the comprehensive quality is greater than or equal to the quality threshold, the ash dish to be tested is judged to be a good product, otherwise the ash dish to be tested is judged to be a defective product or a waste sample.

[0064] Good products can be transported to the next station for shade drying or drying. Defective products or waste samples are taken away and sent to the defective product area.

[0065] Since it is a conventional technical means in the art to extrude the ash dish raw material in the forming mold by an extrusion mechanism to obtain a formed ash dish (i.e., the ash dish to be tested), it will not be described in detail here.

[0066] In the ashtray production equipment, the characteristic data of multiple different dimensions of the ashtray to be detected are first obtained through the multi-dimensional data acquisition module, and then the single quality degree of the ashtray to be detected in each dimension is calculated through the quality calculation module, and the comprehensive quality degree of the ashtray to be detected in multiple different dimensions is calculated according to the single quality degree of the ashtray to be detected in each dimension. Finally, the judgment module judges whether the ashtray to be detected is a good product according to the comprehensive quality degree. The quality degree of the ashtray to be detected can be evaluated from multiple different dimensions, and the comprehensive quality degree is obtained by combining the single quality degrees in multiple different dimensions, which improves the reliability and accuracy of the quality detection of the ashtray to be detected, and avoids the errors and omissions that may exist in the evaluation and detection of the quality of the ashtray to be detected from only a single dimension.

[0067] Compared with the existing ash dish production equipment, the ash dish production equipment determines whether the ash dish to be tested is a good product by detecting the comprehensive quality of the ash dish to be tested, which can avoid the errors and omissions that may exist in the quality evaluation of the ash dish to be tested from only a single dimension, thereby improving the efficiency of ash dish production and the yield rate of the ash dish after shade drying.

[0068] As a preferred technical solution, Figure 3-Figure 6 As shown, the ash dish making equipment also includes a conveyor belt 1, a detection bracket 2 and a clamping mechanism 3.

[0069] The conveyor belt 1 is located below the multi-dimensional data acquisition module and is used to transport the ash dishes to be inspected; the inspection bracket 2 is installed on one side of the conveyor belt 1; the clamping mechanism 3 is installed on the inspection bracket 2 and is located directly above the conveyor belt 1, and is used to clamp defective products and transfer them to the defective product storage area.

[0070] The multi-dimensional data acquisition module and the clamping mechanism 3 are sequentially installed on the detection bracket 2 along the transmission direction of the conveyor belt 1. The clamping mechanism 3 includes a cross slide module that can move along the X-axis and the Y-axis and a clamping tool such as a clamping hand installed on the cross slide module to clamp the ash dish detected as a defective product from the conveyor belt 1. Of course, the clamping mechanism 3 can also be a multi-axis manipulator, and its specific structure will not be repeated here.

[0071] Wherein, the multi-dimensional data acquisition module is fixedly mounted on the detection bracket 2 .

[0072] By providing the clamping mechanism 3 , the ash tray detected as a defective product can be conveniently clamped away from the conveyor belt 1 .

[0073] like Figure 3 , Figure 4 , Figure 5 as well as Figure 6As shown, the ash dish making equipment also includes a forming bracket 4, a discharging mechanism 5, a feeding mechanism 6, a forming mechanism 7 and a pushing mechanism 8.

[0074] The forming support 4 is located at one side of the conveyor belt 1, and the unloading mechanism 5 is installed on the forming support 4, including an extrusion die 50 and an ejection component, and the ejection component is used to eject the formed ash dish in the extrusion die 50 from the extrusion die 50. Specifically, the ejection component can be composed of a hydraulic cylinder 51 and a hydraulic rod 52 that is transmission-coordinated with the hydraulic cylinder 51, the hydraulic rod 52 is transmission-connected to the output end of the hydraulic cylinder 51 and is located above the hydraulic cylinder 51, the hydraulic rod 52 is located below the extrusion die 50 and can move downward relative to the extrusion die 50 under the drive of the hydraulic cylinder 51 to eject the formed ash dish in the extrusion die 50 from the extrusion die 50. For example, the hydraulic rod 52 can be slidably connected to the bottom of the extrusion die 50, and pass through the bottom of the extrusion die 50 under the drive of the hydraulic cylinder 51 to eject the formed ash dish from the extrusion die 50.

[0075] The feeding mechanism 6 is used to convey the ash dish raw material into the extrusion die 50. The feeding mechanism 6 includes a stirring component 60 for stirring the ash dish raw material and a conveying pipe 61 for conveying the stirred ash dish raw material into the extrusion die 50, and the conveying mechanism also includes a moving component 62 that can drive the stirring component 60 and the conveying pipe 61 to move relative to the forming bracket 4; when the feeding mechanism 6 conveys the ash dish raw material into the extrusion die 50, the end of the conveying pipe 61 close to the extrusion die 50 is located between the extrusion die 50 and the forming mechanism 7, and after the feeding mechanism 6 conveys the ash dish raw material, the moving component 62 drives the entire feeding mechanism 6 away from the extrusion die 50, so that the forming mechanism 7 is close to the extrusion die 50 and cooperates with the extrusion die 50 to realize the extrusion molding of the ash dish.

[0076] The molding mechanism 7 is located directly above the unloading mechanism 5, and includes a molding component 70 and a driving component 71. The molding component 70 is installed on the driving component 71. The driving component 71 is fixedly installed on the molding bracket 4 and is used to drive the molding component 70 to move relative to the extrusion die 50 to extrude the ash dish raw material located in the extrusion die 50.

[0077] The molding component 70 matches the extrusion die 50, and both can be set and installed and replaced according to the shape of the ash dish to be produced. The driving component 71 includes but is not limited to a cylinder, a hydraulic cylinder 51 or an electric telescopic rod.

[0078] The pushing mechanism 8 is installed on the forming bracket 4 and is used to push the formed ash tray ejected by the unloading mechanism 5 onto the conveyor belt 1 .

[0079] Preferably, the discharge mechanism 5 further comprises a discharge plate 53, the extrusion die 50 is mounted on the discharge plate 53 and the feed port of the extrusion die 50 faces the molding mechanism 7. A slide rail 80 is mounted on the discharge plate 53, and the push mechanism 8 comprises a push cylinder 81, a push rod 82 and a slider 83 slidably connected to the slide rail 80, and the push mechanism 8 is mounted on the molding bracket 4 through the discharge plate 53. Specifically, the push cylinder 81 is mounted on the end of the discharge plate 53 away from the conveyor belt 1, the output end of the push cylinder 81 is transmission-connected to one end of the push rod 82, the other end of the push rod 82 is fixedly connected to the slider 83, and the push cylinder 81 drives the push rod 82 to move, thereby driving the slider 83 to move along the length direction of the slide rail 80. The length direction of the slide rail 80 is perpendicular to the transmission direction of the conveyor belt 1.

[0080] When the molding mechanism 7 extrude and mold the ash dish raw material in the extrusion die 50 and the molding mechanism 7 returns to the initial position, the ejection component ejects the molded ash dish in the extrusion die 50 from the extrusion die 50. At this time, the pushing cylinder 81 in the pushing mechanism 8 is actuated, and drives the pushing rod 82 to move, driving the slider 83 to move along the length direction of the slide rail 80, thereby pushing the extruded ash dish onto the conveyor belt 1.

[0081] In order to better push the ash dish after extrusion molding onto the conveyor belt 1, the surface of the discharge plate 53 close to the molding mechanism 7 is flush with the upper surface of the conveyor belt 1, and when the slider 83 moves along the length direction of the slide rail 80, the slider 83 fits with the surface of the discharge plate 53 close to the molding mechanism 7, and when the ejection component ejects the molded ash dish in the extrusion mold 50 from the extrusion mold 50, the end of the hydraulic rod 52 away from the hydraulic cylinder 51 is also flush with the surface of the discharge plate 53 close to the molding mechanism 7.

[0082] As a preferred technical solution, the multi-dimensional data acquisition module includes an image acquisition unit and an ultrasonic acquisition unit.

[0083] The image acquisition unit is used to acquire image information of the ash dish to be detected at different angles and different brightnesses, and the ultrasonic acquisition unit is used to transmit a first ultrasonic signal toward the ash dish to be detected and receive a second ultrasonic signal reflected from the ash dish to be detected.

[0084] The characteristic data of multiple different dimensions include the image information and the second ultrasonic signal.

[0085] Specifically, the image acquisition unit includes a plurality of cameras, a pan-tilt for adjusting the camera shooting angle, and an LED lighting lamp with adjustable brightness. The image acquisition unit adjusts the camera shooting angle by controlling the rotation of the pan-tilt, and adjusts the brightness of the gray dish image information to be detected by the camera by controlling the brightness of the LED lighting lamp.

[0086] By acquiring the image information of the ashtray to be inspected at different angles and different brightnesses, compared with the image information of the ashtray to be inspected at a single angle and a single brightness, it is more conducive to the detection of defect information such as cracks and spots on the ashtray to be inspected.

[0087] The second ultrasonic signal is combined with the image information of the ashtray to be detected at different angles and different brightnesses, so as to obtain the comprehensive quality of the ashtray to be detected from multiple different dimensions, thereby improving the reliability and accuracy of ashtray quality detection.

[0088] The present invention also provides a method for making an ash tray, such as Figure 1 As shown, the following steps are included:

[0089] S1, obtain feature data of multiple different dimensions of the ash dish to be detected. The multiple different dimensions here can be understood as different types, and the data features of multiple different dimensions include but are not limited to the pixel grayscale value of a certain area of ​​the ash dish to be detected, the contour shape of a certain area, the voiceprint feature of a certain area and the ultrasonic signal transmitted back, the local and overall image pixel grayscale value and contour line.

[0090] S2, calculating a single quality degree of the ashtray to be inspected in each dimension according to the feature data in multiple different dimensions.

[0091] Preferably, in step S2, Figure 2 As shown, according to the characteristic data of multiple different dimensions, the specific method for calculating the single quality degree of the ashtray to be detected in each dimension includes the following steps:

[0092] S20, obtaining the type of the ashtray to be detected according to the feature data of multiple different dimensions; here, the standard feature data of each dimension of multiple different types of standard ashtrays are obtained in advance, and then according to the feature data of the ashtray to be detected and the standard feature data of the standard ashtray, the degree of correlation between the ashtray to be detected and the standard ashtray in each dimension is compared, and the type of the ashtray to be detected is obtained according to the correlation degree.

[0093] The degree of association Where n represents the number of feature data in a certain dimension and n>1, x i represents the i-th feature data of the gray dish to be detected under a certain dimension, yi Represents the i-th standard feature data of the standard ash dish in a certain dimension. The i-th feature data of the ash dish to be detected in a certain dimension corresponds to the i-th standard feature data of the standard ash dish in a certain dimension. Specifically, for example, when the feature data is image information, the camera shooting angle and brightness corresponding to the i-th image information of the ash dish to be detected in a certain dimension and the i-th standard image information of the standard ash dish in a certain dimension are consistent, or the shooting angle is within the preset angle range and the brightness is within the preset brightness range, so as to more accurately calculate the correlation degree between the ash dish to be detected and the standard ash dish in each dimension.

[0094] Acquiring the type of the ashtray to be detected according to the correlation degree specifically includes: taking the type of the standard ashtray corresponding to the maximum correlation degree as the type of the ashtray to be detected.

[0095] S21, according to the type of the ashtray to be detected, obtaining a plurality of standard feature data of a standard ashtray consistent with the type of the ashtray to be detected and a plurality of defect feature data of a defective ashtray.

[0096] Specifically, first, the standard feature data of multiple different types of standard ashtrays and the defect feature data of multiple defective ashtrays are obtained through the multidimensional data acquisition module, each type of standard ashtray corresponds to multiple standard feature data, and each type of defective ashtray corresponds to multiple standard feature data; according to the type of ashtray to be detected, multiple standard feature data of standard ashtrays consistent with the type of ashtray to be detected and multiple standard feature data of defective ashtrays are obtained.

[0097] S22, obtaining a first correlation weight value between the standard ashtray and the ashtray to be detected in each dimension, and calculating a first quality index in each dimension according to the first correlation weight value, the feature data of the ashtray to be detected and the standard feature data of the standard ashtray.

[0098] The first association weight value between the standard ash dish and the ash dish to be detected in each dimension can be set by a technician. In some cases, the influence of feature data of different dimensions on the evaluation and detection of ash dish quality is not the same. Some dimensional feature data, such as local pixel grayscale value, local second ultrasonic signal, and local or overall edge contour shape, can well reflect the quality of the ash dish to be detected. Some dimensional feature data, such as local contour arc length and texture, are more used to assist in the evaluation and detection of the quality of the ash dish to be detected. The role of setting the first association weight value is to adjust the corresponding first association weight value according to the influence of feature data of different dimensions on the quality of the ash dish to be detected, so as to calculate a more accurate first quality index that conforms to the actual situation according to the first association weight value, the feature data of the ash dish to be detected, and the standard feature data of the standard ash dish, and then evaluate the quality of the ash dish to be detected according to the first quality index. Generally speaking, the larger the value of the first quality index, the higher the quality of the ash dish to be detected.

[0099] The data features of multiple different dimensions include but are not limited to the image pixel grayscale value of a certain area of ​​the ash dish to be detected at a certain angle, the contour shape of a certain area at a certain angle, the voiceprint feature of a certain area and the ultrasonic signal transmitted back, the local and overall image pixel grayscale value and contour at a certain angle, and the texture feature of a certain area. According to the on-site production experience of ash dishes, for the image pixel grayscale value, the corresponding first association weight value is preferably 0.919, for the ultrasonic signal, the corresponding first association weight value is preferably 0.618, for the contour shape, the corresponding first association weight value is preferably 0.247, and for the texture feature, the corresponding first association weight value is preferably 0.131.

[0100] The specific method for calculating the first quality index in each dimension according to the first association weight value, the feature data of the ashtray to be detected, and the standard feature data of the standard ashtray includes: firstly calculating the degree of association between the ashtray to be detected and the standard ashtray in each dimension according to the feature data of the ashtray to be detected and the standard feature data of the standard ashtray, and then calculating the first quality index in a certain dimension according to the degree of association between the ashtray to be detected and the standard ashtray in each dimension and the corresponding first association weight value.

Generally speaking, the larger the value of the second quality index, the lower the quality of the ashtray to be detected.

[0103] Specifically, the second quality index QualityIndex under a certain dimension 2j =ln(Relevance i '×AssociatedWeight 2i );Relevance i ' represents the degree of association between the gray dish to be tested and the defective gray dish in the i-th dimension, AssociatedWeight 2i represents the second association weight value between the defective ashtray and the ashtray to be inspected in the i-th dimension.

[0104] Where n represents the number of feature data in a certain dimension and n>1, x i represents the i-th feature data of the gray dish to be detected under a certain dimension, y i ' represents the i-th standard feature data of the defective ash dish under a certain dimension.

[0105] S24, calculating the single quality index of the ashtray to be detected according to the first quality index and the second quality index. Preferably, the single quality index of the ashtray to be detected in each dimension is SingleQuality=QualityIndex 1j / QualityIndex 2j The larger the single quality degree is, the better the quality of the gray dish to be tested under this dimension is.

[0106] S3, calculating the comprehensive quality of the ashtray to be detected in multiple different dimensions according to the single quality of the ashtray to be detected in each dimension. Among them, m represents the number of dimensions of multiple different dimensions, QualityIndex 1j Represents the first quality index under the jth dimension, QualityIndex 2j represents the second quality index in the j-th dimension.
