[0035] Example 1

[0036] See also Figure 1 The present embodiment provides a digital and intelligent management and control system for accurate quality traceability of glass fiber chopped strand mat, including a raw material information recording module, a raw material information identification module, a workshop environment monitoring module, a product quality early warning module, an operation safety early warning module, a product quality online monitoring module, a product quality online adjustment module, an operation safety online adjustment module, a finished product information recording module, and a finished product quality inspection module for communication and a digital and intelligent management and control platform.

[0037] Among them, the digital management and control platform is the core of the system's operation and control, including the display control system and system server.

[0038] Combine the following Figure 1 Detailed introduction to the functions and working principles of each module:

[0039] Raw material information recording module

[0040] The raw material information recording module records the basic information of the glass fiber filament raw materials, generates a raw material identification tag, and uploads the recorded basic information of the glass fiber filament raw materials to the system server. The raw material information recording module is the primary measure for quality traceability of raw materials. This link records the basic information such as raw material batch, manufacturer, acceptance / quality inspection data through RFID tags and uploads the recorded basic information to the system server for reading and calling during production.

[0041] Raw material information identification module

[0042] The raw material information identification module obtains the basic information of the glass fiber wire material being used for production by reading the raw material identification tag.

[0043] Workshop environment monitoring module

[0044] The workshop environment monitoring module simultaneously monitors workshop environment data that affects the quality of glass fiber chopped strand mat products and workshop operation safety through environmental factor sensors.

[0045] The environment of the glass fiber chopped strand mat production workshop is special. Some environmental indicators not only affect the quality of semi-finished products on the production line, but also are factors that affect the health and safety of personnel, such as high-temperature radiation, suspended matter, toxic or harmful gases, etc. Therefore, this embodiment uses environmental factor sensors to comprehensively monitor the workshop environment data that affect the quality of glass fiber chopped strand mat products and the safety of workshop operations. These sensors include temperature sensors, humidity sensors, suspended matter sensors and at least one gas sensor. The gas sensor mainly monitors specific toxic or harmful gases volatilized from chemical raw materials such as binders, such as sulfur-containing, nitrogen-containing gases or aldehyde-containing volatiles.

[0046] The combination of the above sensors is preferred but not restrictive. At least one environmental factor sensor among the above sensors can simultaneously monitor the same workshop environmental data that affects the quality of glass fiber chopped strand mat products and the safety of workshop operations. For example, when high temperature radiation reaches a certain level, it not only causes harm to the human body, but also affects the physical and chemical properties of the glass fiber by indirectly affecting environmental conditions such as air humidity, thereby affecting the quality of the finished product.

[0047] Product quality early warning module

[0048] The product quality early warning module issues an early warning for abnormal environmental data that may affect product quality based on the workshop environmental data monitored by the workshop environmental monitoring module.

[0049] The product quality early warning module described here uses both sound and visual dual signal alarms.

[0050] Operational safety warning module

[0051] The operation safety early warning module issues an early warning for abnormal environment data that may affect the safety of the workshop operation based on the workshop environment data monitored by the workshop environment monitoring module.

[0052] The operation safety warning module described here also uses dual signal alarms of sound and vision.

[0053] According to the previous introduction, at least one environmental factor sensor can simultaneously monitor the same workshop environmental data that affects the quality of glass fiber chopped strand mat products and the workshop operation safety. Therefore, the product quality warning module and the operation safety warning module here can issue warnings based on different data thresholds for the same workshop environmental data monitored by a certain environmental factor sensor.

[0054] Product quality online monitoring module

[0055] The product quality online monitoring module performs online quality monitoring on the glass fiber chopped strand mat on the production line through quality factor sensors.

[0056] The difference between quality factor sensors and the environmental factor sensors mentioned above is that, compared with the indirectness of environmental factors, the indicators monitored by quality factor sensors are indicators that can directly reflect the real-time quality of the product, such as concentration sensors that monitor binder concentration and visual sensors that monitor carpet quality.

[0057] Product quality online adjustment module

[0058] The product quality online adjustment module adjusts the workshop environment according to the abnormal environment data affecting product quality monitored by the workshop environment monitoring module, and makes direct adjustments according to the product quality anomalies monitored by the product quality online monitoring module.

[0059] The workshop environment is adjusted according to the abnormal environmental data that affects product quality monitored by the workshop environment monitoring module. For example, in order to reduce the impact of high temperature of the production line environment on product quality, the workshop ventilation and cooling equipment is automatically operated until the production line environment temperature drops to a reasonable value.

[0060] Direct adjustments are made based on product quality anomalies detected by the online product quality monitoring module, such as automatically adjusting the raw material ratio to change the binder concentration or floating thread filling to improve the quality of felting.

[0061] The specific means of the above two direct adjustment methods can be that the concentration sensor directly monitors the binder concentration and feeds back the binder concentration information to the control system. The binder liquid preparation system is controlled by the control system. When the binder concentration does not meet the requirements, the control system changes the preparation ratio of one or several raw materials by operating the binder liquid preparation system, thereby adjusting the binder concentration to a reasonable range.

[0062] There are two working modes for floating wire filling based on visual sensor signals, which can be selected according to the conditions of the workshop production line. Figure 2 What is shown is a floating wire filling method with the floating wire filler 3 in front. On this production line, the floating wire filler 3 is arranged on one side of the wire feeder 2. The visual sensor 4 for monitoring the quality of felt laying performs visual inspection on the work-in-progress 1 pressed by the pressing roller 7. The system identifies the quality of felt laying of the work-in-progress 1 by analyzing the image collected by the visual sensor 4, and controls the operation of the floating wire filler 3 according to the identified quality information (density distribution), thereby improving the product quality at the rear. The floating wire filler 3 can selectively float out wire along the width direction of the work-in-progress 1, i.e., fill in the wire at the position where wire is missing or insufficient and needs to be filled.

[0063] Figure 3 What is shown is the floating wire filling method with the visual sensor 4 in front. On this production line, the visual sensor 4 is arranged upstream of the floating wire filler 3. For this purpose, the equipment spacing needs to be adjusted. A group of transparent rollers 8 are installed between the wire feeder 2 and the floating wire filler 3. The collection field of view of the visual sensor 4 faces the transparent rollers 8, and the unbonded felt passing through the transparent rollers 8 is visually inspected. The system identifies the laying quality of the unbonded felt by analyzing the images collected by the visual sensor 4, and controls the operation of the floating wire filler 3 according to the identified quality information (density distribution).

[0064] Operation safety online adjustment module

[0065] The operation safety online adjustment module adjusts the workshop environment according to the abnormal environment data affecting the workshop operation safety monitored by the workshop environment monitoring module.

[0066] The workshop environment is adjusted according to the abnormal environmental data that affects the safety of workshop operations monitored by the workshop environment monitoring module. For example, in order to reduce the radiation to the human body caused by the high temperature of the production line environment or the concentration of some harmful formaldehyde-containing volatiles, the workshop ventilation and heat dissipation equipment is automatically operated until the production line environment temperature drops to a reasonable value or the concentration of the formaldehyde-containing volatiles drops to a reasonable value.

[0067] Finished product information recording module

[0068] The finished product information recording module records the basic information of the finished glass fiber chopped strand mat products that have come off the production line, generates a finished product identification label, and simultaneously uploads the recorded basic information of the finished glass fiber chopped strand mat products to the system server.

[0069] The finished product basic information uploaded to the system server here at least includes the raw material information corresponding to the finished product and the production process monitoring data, and the finished product identification tag can still use the RFID tag introduced above. The raw material information corresponding to the finished product can be directly associated with the basic information identified when the glass fiber wire material is put online through the timer, and the production process monitoring data at least includes the workshop environment data of the entire production process of the glass fiber chopped strand mat finished product monitored by the workshop environment monitoring module, so as to provide accurate quality traceability and analysis.

[0070] Finished product quality inspection module

[0071] The finished product quality inspection module performs quality inspection on the finished glass fiber chopped strand mat and uploads the finished product quality inspection data to the system server.

[0072] Here, the finished product quality inspection module mainly detects quality items that cannot be detected online, such as mechanical properties, weather resistance, etc. Therefore, the finished product quality inspection data includes at least one of mechanical property data and weather resistance data, preferably multiple.

[0073] In this embodiment, the above-mentioned raw material information recording module, raw material information identification module, workshop environment monitoring module, product quality early warning module, operation safety early warning module, product quality online monitoring module, product quality online adjustment module, operation safety online adjustment module, finished product information recording module and finished product quality inspection module all communicate with the digital management and intelligent control platform. The digital management and intelligent platform includes a display control system and the system server mentioned above. With the help of the interconnection between each functional module and the digital management and intelligent platform, the display control system (or control system for short) controls the operation of each module, and collects, records and monitors raw materials, finished products and workshop environment data, online product quality information, etc., so as to provide information support for the accurate traceability of the quality of glass fiber chopped strand mat, realize early judgment and timely early warning of product quality risks and workshop operation safety risks, carry out online rectification of product quality problems through environmental condition adjustment and online automatic adjustment, and eliminate high-risk environmental risks that affect personnel operation safety online.

[0074] Therefore, the technical effect of the embodiment of the present invention is not only to greatly reduce the defective product rate in the workshop and ensure safe production, but also to control the cost of the entire production process of glass fiber chopped strand mat, and promote paperless office and staff reduction.

[0075] The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
