[0038] The embodiments of the present invention provide a method and device for determining the probability of crushing and scratching of a material, which are used to solve the technical problem in the prior art that the probability of crushing and scratching of glass during production and transportation cannot be accurately and quantitatively determined.

[0039] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below 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.

[0040] The present invention provides a method for determining the probability of material scratching, comprising the following steps:

[0041] Weighing the material to be tested to obtain a first weight, that is, the first weight is the original weight of the material to be tested before being processed;

[0042] Cut and break the material to be tested to obtain multiple divided material blocks;

[0043] Clean the attached debris on the surfaces of the plurality of split material blocks, weigh the plurality of split blocks, and obtain a second weight, that is, the second weight is the total weight of the plurality of split material blocks without debris, wherein the attached debris is dirt such as debris, solid and liquid deposits, etc.;

[0044] The weight variation between the first weight and the second weight is calculated, and the probability of compression and scratching of the material to be tested is quantitatively characterized according to the weight variation.

[0045] In this embodiment, the material to be tested is cut and broken to obtain a plurality of divided material blocks, with the purpose of simulating the generation of various debris in the actual production process, such as strip debris and block debris. Strip debris is easy to cause scratches on the material during stacking and transportation, while block debris is easy to cause crushing of the material. The amount of debris formed during the cutting and breaking process is used to judge the probability of crushing and scratching during the cutting and transportation process. Subsequently, the material before and after cutting and breaking is weighed to achieve statistics on the total amount of debris formed, that is, the weight change. The weight change can reflect the probability of crushing and scratching of the material during cutting and transportation using a quantitative characterization relationship. For example, a large weight change indicates that the amount of debris is large, the pressure on the material during the cutting / breaking process is large, and the probability of crushing and scratching during subsequent transportation is high. Otherwise, it indicates that the probability of crushing and scratching is small.

[0046] Based on the above embodiments, this embodiment simulates the material processing process in actual production by cutting and breaking the material, and combines the weighing to count the total amount of debris formed in the material processing process, and then uses the total amount of debris (weight change) to reflect the probability of the material being crushed and scratched during the cutting and transportation process; the method of inferring the probability of crushing and scratching by the total amount of debris can achieve efficient, accurate and rapid material crushing and scratching defect detection, without the need for expensive equipment and professional operators, greatly reducing the cost of material crushing and scratching defect detection, and accurately and quantitatively judging the probability of crushing and scratching of materials during transportation and cutting.

[0047] Compared with the existing technology that only scratches the surface of the material, the existing technology can only scratch the surface of the material and then use various methods to determine the scratch resistance of the material. It is unable to determine the probability of compression and scratching of the material during subsequent stacking and transportation. The method adopted in this solution is to cut and break off the entire material. The entire method is close to the actual production process, and in the process, block-shaped and strip-shaped debris will be formed. If the amount of block-shaped debris is large, the number of cases of compression in the subsequent transportation process will naturally increase, and the probability of compression will increase. Similarly, if the amount of strip-shaped debris is large, the number of scratches in the subsequent transportation process will increase, and the probability of scratches will increase. These block-shaped and strip-shaped debris can be used to determine the probability of compression and scratching of the material during subsequent stacking and transportation.

[0048] See also Figure 1 In a specific embodiment, a method for determining the probability of a material being crushed and scratched is provided, comprising the following steps:

[0049] S1, obtaining a material to be tested, where the material to be tested is glass of a fixed size, and weighing the glass to obtain a first weight.

[0050] Among them, glass is the most common production material. During the transportation process after production, due to the brittleness of glass, even a slight uneven pressure may cause surface scratches. For example, in the stacked transportation of glass, there is not enough spacer between the glasses, and the lower glass will be scratched or indented by the debris of the upper glass. Therefore, the method of judging the probability of glass being scratched is of great significance.

[0051] It should be pointed out that the glass in this embodiment is raw glass, which refers to flat glass that has not been deeply processed. After being drawn, pressed or float produced from a glass furnace, it has only undergone simple annealing treatment and has not been further processed such as cut into specific sizes, edge grinding, tempering, coating, etc.

[0052] In some embodiments, in order to prevent debris and foreign matter from affecting subsequent processing, a cleaning step is further provided. After obtaining the glass, the debris attached to the surface of the glass is cleaned off, the cleaned glass is weighed, and the initial weight is recorded. The first weight obtained is the net weight of the glass. The cleaning methods include washing, sweeping, blowing off, etc. As long as the method can remove the debris attached to the glass surface, it can be used and is not limited here.

[0053] S2, determining the cutting style of the glass, cutting and breaking the glass to obtain a plurality of divided material blocks.

[0054] In some implementation methods of this embodiment, the following steps are included:

[0055] S21, based on a preset pattern, a preset force and a preset speed are used to cut the glass to form a cutting mark with a preset depth. The process of forming the cutting mark will form strip-shaped debris. The strip-shaped debris is the main factor causing the glass to be scratched during the subsequent transportation friction process, that is, during the stacking and transportation process, these strip-shaped debris exist between the glass and the glass, causing the glass to be scratched. The cutting process can simulate the production process of the production line, simulate the generation of strip-shaped debris in the production process, and deduce the probability of glass scratches during the subsequent transportation process through the amount of strip-shaped debris generated.

[0056] In this step, by testing different glasses, the situations under different conditions can be obtained, and the most suitable preset parameters can be obtained based on different situations. For example, after testing plain panels, tempered panels, and coated panels, the most suitable preset parameters are obtained, which can be applicable to different glass materials.

[0057] Specifically, the most suitable preset parameters are to cut the glass sample with the same force and the same movement speed. During the cutting process, the cutting force is maintained at 0.5-1.5N and the cutting speed is 7-11mm / s, so that the depth of the cutting mark is 7-10 microns, ensuring that the force of the cutting mark is basically the same each time, avoiding one cut being too deep and another being too shallow, resulting in a huge difference in the weight change finally measured. Of course, due to factors such as materials and tools, inevitable errors will occur, and the consistency and comparability of each cut can be ensured within the error range.

[0058] In some cutting scenarios of this example, when the glass to be cut is a plain plate, the cutting force is controlled to be 0.9-1.1N and the cutting speed is controlled to be 9-11mm / s, so that the depth of the cutting mark is 9-10 microns.

[0059] In some cutting scenarios of this example, when the glass to be cut is soda-lime glass, the cutting force is controlled to be 0.5-1.0 N and the cutting speed is controlled to be 7-10 mm / s, so that the depth of the cutting mark is 8-10 microns.

[0060] In some cutting scenarios of this example, when the cut glass is medium aluminum glass, the cutting force is controlled to be 0.9-1.1N and the cutting speed is 9-11mm / s, so that the depth of the cutting mark is 9-10 microns.

[0061] In some cutting scenarios of this example, when the cut glass is high-aluminum glass, the cutting force is controlled to be 1.3-1.5N and the cutting speed is 9-11mm / s, so that the depth of the cutting mark is 7-10 microns.

[0062] From the above, we can see that when facing different materials, although the applied force and movement speed are different, the difference in applied force and movement speed is aimed at making the depth of the cutting knife mark between 7-10 microns, so that these parameters can be used for different glass materials to form similar knife marks or similar breaking effects.

[0063] It should be pointed out that the preset pattern is determined according to the cutting style, which can be a grid pattern, a circular curve pattern, or a combination of pattern cutting; the preset pattern can be formed by any one of the template method, CNC cutting method, hand-drawing method and photolithography method, which is not limited here.

[0064] In some embodiments, in order to prevent debris and foreign matter from affecting subsequent processing, a cleaning step is further provided. After cutting the glass to form a cutting mark, the glass is cleaned to remove the debris attached to the surface of the glass to facilitate subsequent processing.

[0065] In some embodiments, in order to record the amount of strip-like debris, a weighing step is further provided. After cutting the glass to form a cutting mark and cleaning off the attached debris on the surface, the weight of the glass is weighed to obtain an intermediate weight. The intermediate weight is the weight of the glass without the strip-like debris.

[0066] S22, breaking the glass according to the cutting knife marks to obtain multiple divided material blocks. In the process of breaking a whole piece of glass into multiple divided materials, block-shaped glass fragments will be formed. Block-shaped glass is the main factor causing glass to be crushed during subsequent transportation friction. The breaking process is similar to the cutting process. The probability of glass being crushed during subsequent transportation can be deduced through the amount of block-shaped debris generated.

[0067] Specifically, during the breaking process, the material to be tested will be broken along the cutting knife marks on the back side of the material to be tested. The breaking force during the breaking process is 0.25N-0.4N, and multiple divided material blocks are obtained. That is, the glass is broken on the back side of the knife marks. The fracture starts from the root of the knife marks, and the stress is mainly concentrated on the back side of the knife marks. In this case, the stress is released along the preset groove direction, and the glass can be cracked in a relatively neat manner, so the debris produced is mainly relatively regular block fragments.

[0068] S3, cleaning the attached debris on the surfaces of the plurality of divided material blocks, weighing the plurality of divided blocks to obtain a second weight, where the obtained second weight is the total weight of the glass after being cut and broken without removing all attached debris.

[0069] S4, calculate the weight change between the first weight and the second weight, and quantitatively characterize the probability of crushing and scratching of the material to be tested according to the weight change. The weight change includes strip-shaped debris and block-shaped debris. The strip-shaped debris can mainly reflect the scratch probability of the glass, while the block-shaped debris can mainly reflect the crushing probability of the glass. The weight of the two directly reflects the possible crushing and scratching probability of the glass during transportation, thereby realizing the quantitative characterization of the crushing and scratching probability.

[0070] The method of quantitatively characterizing the scratch probability of the material to be tested by the weight change includes a method of presetting a lookup table or a method of a scratch probability formula.

[0071] In this embodiment, the preset lookup table is:

[0072] The weight change is more than 0.00867g, which corresponds to a high probability of pressure scratches;

[0073] The weight variation is 0.00232g-0.00867g, corresponding to a medium probability of compression and scratching;

[0074] The weight change is less than 0.00232 g, which corresponds to a small probability of pressure scratches.

[0075] The preset lookup table is based on Figure 2 The probability of scratching is low. Figure 3 The probability of scratches is summarized through statistics and analysis in multiple tables. When the weight change (i.e. the total amount of broken glass fragments from a single glass sampled) is above 0.00867g, 30% of customers complain about scratches, and 25% of customers complain about crushing injuries. In this case, the probability of crushing scratches is high. When the weight change is below 0.00232g, 5% of customers complain about scratches, and 3% complain about crushing injuries. In this case, the probability of crushing scratches is low.

[0076] In specific implementation, after obtaining the weight change, determine which range of the preset lookup table the weight change falls into, and then determine the compression scratch probability corresponding to the range to obtain the compression scratch probability of the glass during production and transportation.

[0077] In this embodiment, the formula for the probability of pressure scratching is:

[0078]

[0079] In the above formula, is the probability of pressure scratch, is the first constant, It is the weight change of the material to be tested before and after it is cut and broken. is the second constant, is the thickness of the material to be measured, is the number of cutting knives.

[0080] In this formula, the weight change before and after the glass is cut and broken is an important indicator that affects the probability of compression scratches. That is, as the weight change (i.e., debris) increases, the probability of glass compression scratches caused by debris during subsequent transportation will be higher. The amount of debris and the probability of compression scratches show a linear positive growth relationship. If the weight change remains unchanged, but the thickness of the material to be tested and the number of cutting knives increase, it proves that the quality of the glass is good and the probability of compression scratches is low.

[0081] The numerical values ​​of the first constant and the second constant can be determined by Figure 2 The data table of glass with low probability of scratching when the thickness of medium glass is 1.1mm and the number of cutters is 10. Figure 3 The data table of glass with a high probability of scratching when the glass thickness is 1.1mm and the number of cutting knives is 10, as well as the pressure scratch situation represented by the customer complaint ratio are fitted and determined.

[0082] In specific implementation, after obtaining the weight change, the weight change is substituted into the compression scratch probability formula to obtain the compression scratch probability.

[0083] In some possible embodiments, the amount of strip debris and the probability of scratches can also be determined separately, that is, the difference between the intermediate weight and the first weight is calculated, and the mapping formula is determined by fitting the difference with the complaint ratio, and then the scratch probability represented by the amount of strip debris is determined.

[0084] In some other possible embodiments, the amount of blocky debris and the probability of crushing injury can also be determined separately, that is, the difference between the intermediate weight and the second weight is calculated, and the mapping formula is determined by fitting the difference with the complaint ratio, and then the probability of crushing injury represented by the amount of blocky debris is determined.

[0085] It should be pointed out that after determining the glass compression scratch situation, the glass cutting process can be optimized and the annealing process parameters can be adjusted based on the statistical and analysis results to reduce the pressure and damage to the glass during the cutting process, reduce the probability of glass compression scratches, and improve the quality of the glass and production efficiency.

[0086] In an application embodiment, glass with a size of 100mm*100mm and a thickness of 1.1mm was used. The above method was executed and the first weight was measured to be 27.2492g; the glass was then divided into 10 pieces. During the cutting process, the cutting force and speed were controlled at 1N and 10mm / s, and the weight after cutting was 27.2450g; the glass was then broken along the cutting knife marks, and the broken glass was weighed to be 27.2400g, that is, the second weight was 27.2400g, and the weight change was 0.0092g. According to the preset lookup table, it can be seen that more glass chips are generated in the cutting process, and the probability of compression scratches is relatively high.

[0087] In another application embodiment, a glass with a size of 100mm*100mm and a thickness of 1.1mm was used. The above method was executed and the first weight was measured to be 27.7365g; the glass was then divided into 10 pieces. During the cutting process, the cutting force and speed were controlled at 1N and 10mm / s, and the weight after cutting was 27.7355g; the glass was then broken along the cutting knife marks, and the broken glass was weighed to be 27.7342g, that is, the second weight was 27.7342g, and the weight change was 0.0023g. According to the preset lookup table, it can be seen that less glass chips are generated during the cutting process, and the probability of compression scratches is small.

[0088] It can be seen from the above embodiments that a method for judging the probability of material compression and scratching proposed by the present invention can be applied to the judgment of the probability of compression and scratching in the process of glass production and transportation. First, the initial glass is weighed to obtain a first weight; then the glass is cut and broken to obtain a plurality of divided material blocks, and then the attached debris on the surfaces of the plurality of divided material blocks is cleaned, and the plurality of divided blocks are weighed to obtain a second weight; the weight change between the first weight and the second weight is calculated, and the compression and scratching probability of the material to be tested is quantitatively characterized according to the weight change; the present invention generates strip-shaped debris and block-shaped debris during the cutting and breaking process, and weighs and counts the amounts of the two to simulate the debris occurring in the production process, so as to judge the probability of compression and scratching occurring during stacking and transportation, thereby reducing the detection cost and improving the product quality.

[0089] In some other embodiments, the method for judging the probability of crushing and scratching of materials proposed in the present invention can be used for materials other than glass, such as metal materials, plastics, etc. These materials are similar to glass materials. During transportation, they are easily mixed with debris, resulting in crushing and scratching between materials. When executing the above method, the amount of debris can also be used to judge the probability of crushing and scratching during subsequent production and transportation.

[0090] Based on the above method for determining the probability of material being crushed and scratched, the present invention also provides a device for determining the probability of material being crushed and scratched, comprising:

[0091] A weighing mechanism, used for weighing an object;

[0092] The cutting mechanism is used to cut the material to be tested to form a cutting mark.

[0093] A breaking mechanism is used to break the material to be tested along the cutting knife marks;

[0094] A cleaning mechanism, used for cleaning the attached debris on the surfaces of the plurality of divided material blocks;

[0095] The computing mechanism includes a processor and a memory; the memory is used to store program codes and transmit the program codes to the processor; the processor is used to execute the above-mentioned method for determining the probability of material compression scratch according to the instructions in the program codes.

[0096] During specific implementation, the glass is first cleaned for the first time by a cleaning mechanism, and then the glass is weighed for the first time by a weighing mechanism to obtain a first weight; then a cutting mark is formed on the glass surface by a cutting mechanism; then the glass is cleaned for the second time by a cleaning mechanism; then the glass is broken by a breaking mechanism; then the glass is cleaned for the third time by a cleaning mechanism; after the third cleaning is completed, the glass is weighed for the second time by a weighing mechanism to obtain the results of the two weighings, which are input into a calculation mechanism to execute a program code to obtain the probability of compression scratches.

[0097] From the above, it can be seen that the device of this embodiment can process glass in batches. The amount of glass fragments can be used to determine whether broken glass fragments appear on the glass surface during the cutting / breaking process, and the probability of compression and scratches during stacking and transportation can be determined in turn.

[0098] In a specific embodiment, the weighing mechanism can be a traditional mechanical weighing mechanism, such as a spring scale, etc.; it can also be an electronic scale that combines high-precision sensors and advanced signal processing technology. As long as the weighing mechanism can realize the weighing function, technical personnel in this field can use it, and this solution does not limit this.

[0099] In a specific embodiment, the cutting mechanism can be a glass knife cutting tool, a diamond knife cutting tool, a water jet cutting tool, or a laser cutting tool. As long as the cutting mechanism can cut and form cutting marks on the material to be tested, technical personnel in this field can use it, and this solution does not limit this.

[0100] In a specific embodiment, the breaking mechanism includes a clamping member and a lifting member. The clamping member is used to be fixed on the glass to keep the glass from displacement, and the lifting member is used to give the glass an upward lifting force to achieve the breaking of the glass. As for the specific structure of the lifting member, this solution does not limit it.

[0101] In a specific embodiment, the cleaning mechanism can be a cleaning tool, an adsorption tool, or a cleaning tool. As long as it can clean the attached debris on the surface of the material to be tested, technical personnel in this field can use it, and this solution does not limit this.

A computer-readable storage medium is used to store program codes, and the program codes are used to execute the above-mentioned method for determining the probability of material being crushed and scratched.

Based on this understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art or all or part of the technical solution can be embodied in the form of a software product.
