Description

Technical Field

[0001] The invention relates to the technical field of insulating varnish measurement, and in particular to a system and method for measuring the usage of insulating varnish for enameled wires. Background Art

[0002] In the enameled wire industry, the application of insulating varnish occupies a pivotal position. However, its physical and chemical properties pose a great challenge to accurate measurement in the production process. Insulating varnish itself has the characteristics of high viscosity, certain corrosive components, easy volatility and often a mixture. These characteristics are intertwined, making it extremely difficult to accurately measure the weight of insulating varnish through conventional flow measurement, density calculation or volume estimation methods.

[0003] Specifically, high viscosity means that insulating paint is difficult to control during flow and difficult to measure accurately through equipment such as flow meters; corrosive components may damage measuring equipment, affecting measurement accuracy and service life; volatility means that the weight of insulating paint may change due to volatilization during measurement and storage; and as a mixture, the proportion of components in insulating paint may vary from batch to batch, further increasing the complexity of weight calculation.

[0004] Therefore, in the actual production process, it is often difficult for enterprises to accurately calculate the weight of insulating paint used for each order in real time. This results in the cost accounting only being able to adopt the allocation calculation method at the end of the month or in the middle of the month, that is, the total amount of insulating paint used in a period of time is allocated to each order according to a certain ratio or method. Although this allocation calculation method reflects the use of insulating paint to a certain extent, it undoubtedly reduces the accuracy of order costs and is not conducive to the company's refined management and cost control.

[0016] Preferably, a paint pump is also provided in the paint box, and the measurement system further comprises:

[0017] The paint adding module is connected to the paint adding pump and the data acquisition module, and is used to control the paint adding pump to add insulating paint to the paint box every time the insulating paint liquid level reaches the lowest point, and then control the paint adding pump to stop adding insulating paint when the insulating paint liquid level reaches the highest point.

[0018] Preferably, it also includes a two-color indicator light connected to the paint adding module, when the paint adding module controls the paint adding pump to add insulating paint to the paint box, the two-color indicator light emits a first color; when the paint adding module controls the paint adding pump to stop adding insulating paint to the paint box, the two-color indicator light emits a second color.

[0019] Preferably, the liquid level sensor is an ultrasonic sensor, which is arranged on the top inner wall of the paint box.

[0042] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment, and other embodiments may also fall within the scope of the present invention as long as they conform to the gist of the present invention.

[0043] In a preferred embodiment of the present invention, based on the above problems existing in the prior art, a system for measuring the amount of insulating varnish used for enameled wire is provided. Figure 1 As shown, including:

[0044] A gravity sensor 1 is provided at the bottom of the paint box and is used to detect the weight of the insulating paint in the paint box;

[0045] The liquid level sensor 2 is arranged inside the paint box and is used to detect the insulating paint liquid level in the paint box;

[0046] The data acquisition module 3 is connected to the weight sensor 1, the liquid level sensor 2 and the production system MES respectively, and is used to record the corresponding time point and the weight of the insulating paint when the work order assigned by the production system starts production, when the insulating paint liquid level reaches the lowest point or the highest point each time, and when the work order ends production, thereby generating an insulating paint consumption curve;

[0047] The usage measurement module 4 is connected to the data acquisition module 3, and is used to divide the insulating paint consumption curve into multiple insulating paint consumption intervals, calculate the insulating paint consumption in each insulating paint consumption interval, and then accumulate the insulating paint consumption to obtain the insulating paint usage corresponding to the current work order.

[0048] Specifically, in this embodiment, a weight sensor 1 is arranged at the bottom of the paint box which is not connected to the outside world, and a liquid level sensor 2 is arranged inside. The weight of the insulating paint in the paint box is measured in real time by the gravity sensor 1, thereby avoiding measurement difficulties caused by characteristics such as high viscosity and easy volatility. Compared with methods such as flow measurement, density calculation or volume estimation, the accuracy and reliability of the insulating paint weight data are improved.

[0049] The liquid level sensor 2 can monitor the changes in the liquid level of the insulating paint in real time, ensuring that data is recorded in time when the liquid level reaches the lowest point or the highest point, which helps to timely discover the consumption of the insulating paint and avoid overuse or underuse.

[0050] For each work order issued by the generation system, the corresponding time points and the corresponding insulating paint weights are recorded at the four key production links: when the work order starts production, when the liquid level sensor detects that the insulating paint liquid level reaches the lowest point, when the liquid level sensor detects that the insulating paint liquid level reaches the highest point, and when the work order ends production, so as to generate an insulating paint consumption curve. The insulating paint consumption curve can intuitively display the use of insulating paint, which is convenient for enterprises to analyze and manage.

[0051] The consumption curve is then divided into multiple consumption intervals, and the insulating paint consumption in each consumption interval is calculated. By accumulating the insulating paint consumption in each consumption interval, the insulating paint usage corresponding to the current work order is obtained. Compared with the traditional method of allocating calculations at the end or middle of the month, this measurement system can measure the insulating paint usage for each work order individually and accurately, which improves the accuracy of order costs and is conducive to the company's refined management and cost control.

[0052] In a preferred embodiment of the present invention, Figure 2 As shown, the data acquisition module 3 includes:

[0053] The time point numbering unit 31 is used to initialize the number of times n of adding paint when the work order starts production, and record the corresponding time point and the corner mark of the insulating paint weight as n, and then increase the number of times of adding paint each time the insulating paint liquid level reaches the lowest point, and record the corresponding time point and the corner mark of the insulating paint weight as (2n-1), when the insulating paint liquid level reaches the highest point, record the corresponding time point and the corner mark of the insulating paint weight as (2n), and when the work order ends production, record the corresponding time point and the corner mark of the insulating paint weight as (2n+1);

[0054] The curve generating unit 32 is connected to the time point labeling unit 31 and is used to sort the corresponding insulating paint weights according to the subscripts of each time point in ascending order to obtain an insulating paint consumption curve.

[0055] Specifically, Figure 3 As shown, it is a flow chart of the recording process of time points and insulating paint weights with the generation process as the logical main body. After recording all the time points and insulating paint weights, the corresponding insulating paint weights are sorted in the order of the time point subscripts from small to large to obtain the insulating paint consumption curve;

[0056] like Figure 4 The figure shows the consumption curve of insulating paint after adding paint twice (n=2). Figure 3 The paint consumption rate and paint addition rate are both idealized as fixed speeds). Specifically, combined with Figure 2 The flow chart is obtained Figure 3 The process of the insulating paint consumption curve is as follows:

[0057] Record the time point t0(t n ,n=0), weight of insulating varnish m0(m n ,n=0);

[0058] The insulating paint starts to be consumed. When the insulating paint level reaches the lowest point for the first time, the paint adding times are increased (n+1=1) and the time point t1 (t 2n-1 ,n=1) weight of insulating varnish m1(m 2n-1 ,n=1);

[0059] After the paint is added, when the insulating paint liquid level reaches the highest point for the first time, record the time point t2 (t 2n ,n=1) weight of insulating paint m2(m 2n ,n=1);

[0060] Continue to consume insulating paint. When the insulating paint level reaches the lowest point for the second time, add one more time (n+1=2) to record the time point t3 (t 2n-1 ,n=2) weight of insulating paint m3(m 2n-1 ,n=2);

[0061] After the paint is added, when the second insulating paint level reaches the highest point, record the time point t4 (t 2n ,n=2) weight of insulating varnish m4(m 2n ,n=2);

[0062] Continue to consume insulating paint, record the time point t5 (t 2n+1 ,n=2) weight of insulating varnish m0(m 2n＝1 ,n=2);

[0063] Furthermore, it can be seen that according to different calculation formulas for the corner marks, we can accurately know which production link the time points of different corner marks correspond to according to the value of the number of times n of adding paint. That is, if 2n-1 is satisfied, it means that the production link corresponding to this time point is the nth time that the liquid level reaches the lowest point; if 2n is satisfied, it means that the production link corresponding to this time point is the nth time that the liquid level reaches the highest point; if 2n+1 is satisfied, it means that the production link corresponding to this time point is the end of the work order.

[0064] Further, in this embodiment, if Figure 2 As shown, the usage measurement module 4 includes:

[0065] The interval division unit 41 is used to use each time point with an even-numbered subscript and the next time point as the starting point and the end point of the corresponding insulating paint consumption interval, respectively, to obtain a plurality of insulating paint consumption intervals;

[0066] The usage measurement unit 42 is connected to the interval division unit 41, and is used to subtract the insulating paint weight corresponding to the end point from the insulating paint weight corresponding to the starting point for each insulating paint consumption interval to obtain the insulating paint consumption in each insulating paint consumption interval, and then accumulate the insulating paint consumption to obtain the insulating paint usage corresponding to the current work order.

[0067] Specifically, in this embodiment, from Figure 3 The insulating paint consumption curve can be seen from:

[0068] In the interval t0-t1, the weight of the insulating paint decreases from m0 to m1;

[0069] In the interval t1-t2, the weight of insulating paint increases from m1 to m2;

[0070] In the interval t2-t3, the weight of insulating paint decreases from m2 to m3;

[0071] In the interval t3-t4, the weight of insulating paint increases from m3 to m4;

[0072] In the interval t4-t5, the weight of insulating paint decreases from m4 to m5;

[0073] Therefore, we can draw a rule that the starting point of each insulating paint consumption interval is a time point with an even number as the subscript, and the end point of each insulating paint consumption interval is a time point with an odd number as the subscript; the insulating paint weight corresponding to the starting point of the insulating paint consumption interval is subtracted from the insulating paint weight corresponding to the end point of the insulating paint consumption interval to obtain the insulating paint consumption in each insulating paint consumption interval. According to this rule, the calculation formula for the insulating paint consumption in each insulating paint consumption interval can be derived:

[0074] m i -m i+1 , i=0,2,4......

[0075] Furthermore, the following formula is derived:

[0076]

[0077] Among them, C is the usage of insulating paint corresponding to the current work order, (m i -m i+1 ) is the insulating paint consumption in each insulating paint consumption interval.

[0078] In a preferred embodiment of the present invention, a paint pump 5 is further provided in the paint box, and the measuring system further comprises:

[0079] The paint adding module 6 is connected to the paint adding pump 5 and the data acquisition module 3, and is used to control the paint adding pump to add insulating paint to the paint box every time the insulating paint liquid level reaches the lowest point, and then control the paint adding pump to stop adding insulating paint when the insulating paint liquid level reaches the highest point.

[0080] Specifically, in this embodiment, Figure 1 As shown, a paint adding pump is also provided for automatically adding paint and automatically stopping adding paint according to the liquid level detection result of the liquid level sensor to avoid overuse or underuse.

[0081] In addition, the automatic paint adding method does not require opening the paint box, thus avoiding the problem of inaccurate weight measurement caused by the evaporation of the insulating paint in the paint box to the outside of the paint box.

[0082] In a preferred embodiment of the present invention, it also includes a two-color indicator light 7, which is connected to the paint adding module 6. When the paint adding module 6 controls the paint adding pump 5 to add insulating paint to the paint box, the two-color indicator light 6 emits a first color; when the paint adding module 6 controls the paint adding pump 5 to stop adding insulating paint to the paint box, the two-color indicator light 7 emits a second color.

[0083] Specifically, in this embodiment, Figure 1 Also shown is a two-color indicator light for indicating the working status of the paint pump.

[0084] In a preferred embodiment of the present invention, the liquid level sensor 2 is an ultrasonic sensor, which is arranged at the top of the interior of the paint box and is used to detect the liquid level of the insulating paint in the paint box.

[0085] Specifically, in this embodiment, Figure 1 The liquid level sensor shown in the figure adopts a floating liquid level sensor, which floats on the surface of the insulating paint. Although it can measure the liquid level of the insulating paint, the insulating paint is corrosive. This type of liquid level sensor must be made of non-metallic and corrosion-resistant materials;

[0086] In addition, the floating liquid level sensor cannot solve the measurement problems caused by high viscosity and different densities of different paints. In order to avoid these problems, the liquid level sensor in this embodiment adopts an ultrasonic sensor to measure the insulating paint level based on the distance from the liquid surface of the insulating paint. It does not contact the insulating paint, and can avoid measurement problems caused by corrosion, high viscosity, and different densities of different paints.

[0087] The present invention also provides a method for measuring the amount of insulating varnish used for enameled wires, which is applied to the above-mentioned measuring system, such as Figure 5 As shown, including:

[0088] Step S1, the measuring system records the corresponding time points and insulating paint weights when the work order assigned by the production system starts production, when the insulating paint liquid level reaches the lowest point and the highest point each time, and when the work order ends production, thereby generating an insulating paint consumption curve;

[0089] Step S2, the measurement system divides the insulating paint consumption curve into multiple insulating paint consumption intervals, calculates the insulating paint consumption in each insulating paint consumption interval, and then accumulates the insulating paint consumption to obtain the insulating paint usage corresponding to the current work order.

[0090] In a preferred embodiment of the present invention, Figure 6 As shown, step S1 includes:

[0091] Step S11, the measurement system initializes the number of times n of adding paint to 0 when the work order starts production, and records the corresponding time point and the corner mark of the insulating paint weight as n, then increases the number of times of adding paint once each time the insulating paint liquid level reaches the lowest point, and records the corresponding time point and the corner mark of the insulating paint weight as (2n-1), each time the insulating paint liquid level reaches the highest point, the corresponding time point and the corner mark of the insulating paint weight are recorded as (2n), and when the work order ends production, the corresponding time point and the corner mark of the insulating paint weight are recorded as (2n+1);

[0092] Step S12, the measuring system sorts the corresponding insulating paint weights according to the subscripts of each time point in ascending order to obtain an insulating paint consumption curve.

[0093] In a preferred embodiment of the present invention, Figure 7 As shown, step S2 includes:

[0094] Step S21, the measuring system uses each time point with an even-numbered corner mark and the next time point as the starting point and the end point of the corresponding insulating paint consumption interval, and divides it into multiple insulating paint consumption intervals;

[0095] In step S22, for each insulating paint consumption interval, the measuring system subtracts the insulating paint weight corresponding to the end point from the insulating paint weight corresponding to the starting point to obtain the insulating paint consumption in each insulating paint consumption interval, and then accumulates the insulating paint consumption to obtain the insulating paint usage corresponding to the current work order.

[0096] In a preferred embodiment of the present invention, a paint pump is also provided in the paint box, and the measuring system also includes an automatic paint adding process, including:

[0097] The measuring system controls the paint adding pump to add insulating paint to the paint box each time the insulating paint liquid level reaches the lowest point, and then controls the paint adding pump to stop adding insulating paint when the insulating paint liquid level reaches the highest point.

[0098] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of this specification and illustrations should be included in the protection scope of the present invention.
