Description

Technical Field

[0001] The present invention relates to a gasket production technology, and more specifically, to a gasket production process. Background Art

[0002] Gasket is an important component used on the relay base.

[0003] The traditional gasket production process generally has problems such as imperfect inspection links, inability to monitor the production environment in real time, and improper handling of raw materials, which leads to low qualified product rates and affects product performance and production efficiency. Therefore, it is very important to develop a standardized, normalized, and real-time monitored gasket production process. Summary of the invention

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a high-efficiency and high-precision gasket production process.

[0005] To achieve the above object, the present invention provides the following technical solution: a gasket production process, comprising the following steps:

[0006] S1. Raw material procurement: First, purchase raw materials that meet the standards according to production needs, ensure that the source of the raw materials is traceable and has qualified quality certification;

[0007] S2. Raw material inspection: When the raw materials arrive at the production plant, they are first inspected for appearance, size and material, including:

[0008] S21. Appearance inspection: Check the surface of raw materials visually to ensure that the surface is flat and smooth without obvious burrs or bruises. Each batch of materials must be sampled for inspection. The sampling method is to inspect both ends of the materials and fill in the incoming material inspection record sheet.

[0009] S22. Dimension inspection: Inspect the width and thickness of the raw materials to ensure that they meet the tolerance requirements; use a vernier caliper and an outside micrometer to measure the width and thickness respectively. Each batch of materials must be sampled and inspected, and each measurement is made 5 times from both ends of the material, and the results are recorded in the incoming material inspection record sheet;

[0010] S23, Material inspection: Confirm whether the material meets the ST12 standard through outsourcing inspection, and the inspection cycle is once every quarter;

[0011] If unqualified raw materials are found during the inspection process, timely feedback and return are required;

[0012] S3. Material storage: After the raw materials have passed the above inspections, the qualified raw materials will be transported to the warehouse by carts or pallets and transferred to the storage stage;

[0013] S4. Raw material storage: Qualified raw materials should be stored in a raw material warehouse with controlled environment. To ensure that the storage conditions of raw materials are appropriate, a thermometer and hygrometer are used to monitor the storage environment in real time to ensure that the storage temperature and humidity meet the requirements. At the same time, a detection module is set up for real-time monitoring. Once the storage environment temperature or humidity is abnormal, the system will automatically start the air conditioner for adjustment to ensure that the material storage environment always meets the requirements. The data is recorded in real time, and the temperature and humidity record sheet is checked and archived daily.

[0014] S5. Stamping: When processing is required, a 25T automatic punch press is used to stamp qualified raw materials. After stamping, the finished product undergoes the first inspection, including:

[0015] S51. Appearance inspection: ensure that there are no obvious defects in the appearance of the finished product after stamping;

[0016] S52, Dimension inspection: Use a vernier caliper to check the dimensions of the finished product after stamping. The inspection frequency is once every 2 hours, and 5 pieces are selected for inspection each time to ensure that the size requirements are met;

[0017] If there are defective products, they should be reworked or scrapped in time and recorded in the first inspection record sheet;

[0018] S6, Gasket tapping: tap the qualified stamping products and conduct a second inspection after tapping, including:

[0019] S61. Appearance inspection: ensure that the finished product has no obvious defects after tapping;

[0020] S62, Dimension inspection: Use M3 thread go and no-go gauge to inspect each thread to ensure that it meets the dimensional requirements;

[0021] If there are any unqualified products, they should be scrapped in time and the inspection results should be recorded;

[0022] S7, Surface treatment: The tapped product is surface treated and subjected to a third inspection, including:

[0023] S71. Appearance inspection: Ensure that the surface of the product after treatment is bright and has no obvious blackening;

[0024] S72, film thickness inspection: ensure that the film thickness meets the standard requirements and at least meets the Zn5 requirements;

[0025] S73, ROHS Directive Inspection: Outsource inspection to see if the product complies with the environmental protection requirements of the ROHS Directive. The inspection frequency is once a year;

[0026] S74, Salt spray test: The finished products are subjected to salt spray test by using a salt spray test machine to ensure that there is no blackening or rust within 24 hours. The inspection frequency is 5 per batch;

[0027] For unqualified products, rework or scrap them in time and record the test results;

[0028] S8, Finished product inspection: After the surface treatment is qualified, the finished product will enter the final inspection stage, including:

[0029] S81. Appearance inspection: Ensure that the finished product has a smooth and flat appearance, no burrs, and no mixing of materials;

[0030] S82, Dimension inspection: Use a vernier caliper to inspect the dimensions of the finished products one by one to ensure that they meet the dimensional requirements;

[0031] S83. Inspection records are recorded through the finished product inspection record sheet;

[0032] S9, Packaging and Warehousing: When the finished product passes the inspection, it will be packaged, including:

[0033] S91. Packaging requirements: Ensure that the packaging is flat, undamaged, and meets transportation and storage requirements;

[0034] S92, Warehouse management: After packaging, qualified finished products will be sent to the finished product warehouse via pallets or carts;

[0035] S10. Finished product storage: Packaged finished products should be stored in a finished product warehouse with controlled environment. A thermometer and hygrometer should be used to monitor the storage environment in real time to ensure that the storage temperature and humidity meet the requirements. At the same time, a detection module should be set up for real-time monitoring. Once the storage environment temperature or humidity is abnormal, the system will automatically start the air conditioner to adjust it to ensure that the material storage environment always meets the requirements. The data should be recorded in real time, and the temperature and humidity record sheet should be checked and filed daily.

[0036] S11. Outbound delivery and distribution: When finished products need to be shipped out, operators will confirm the finished products by checking with the shipping order. After ensuring that they are correct, they will be sent out of the warehouse by cart or pallet. During the outbound delivery process, the loading process should be supervised throughout to prevent the products from being damaged or dropped due to improper transportation.

[0037] The present invention is further configured as follows: in S22, the tolerance requirements include a width tolerance of -0.2 mm and a thickness tolerance of ±0.03 mm.

[0038] The present invention is further configured as follows: in S4 and S10, the storage temperature and humidity requirements are that the temperature is maintained between 5° C. and 40° C., and the humidity does not exceed 80%.

[0039] The present invention is further configured as follows: in the S52 and S82, the size requirement is 3.7 mm ± 0.2 mm.

[0040] The present invention is further configured as follows: in S4 and S10, the detection module includes a sensor unit for real-time monitoring of temperature and humidity and a control unit for receiving data from the sensor unit and controlling the operating state of the air conditioner according to the data results, and the detection method includes:

[0041] S4101, sensor unit monitors temperature and humidity in real time:

[0042] In the storage environment, the sensor unit monitors the temperature and humidity of the current environment in real time and transmits the data to the control unit, which makes judgments based on the temperature and humidity data;

[0043] S4102, temperature judgment:

[0044] When the sensor unit detects that the current temperature is lower than 5°C, it goes to S4103; if the temperature is between 5°C and 40°C, the control unit goes to S4106; if the temperature is higher than 40°C, it goes to S4105;

[0045] S4103, when the temperature is lower than 5℃, start the air conditioning heating:

[0046] When the temperature value is lower than 5°C, the control unit will control the air conditioner to start the heating mode and adjust the indoor temperature for a heating time of T1. After T1, the sensor unit detects the temperature again. If the temperature reaches above 5°C, the process goes to step S4104.

[0047] S4104, when the temperature reaches 5℃ or above, determine the temperature range:

[0048] During the heating process of the air conditioner, when the temperature rises to 5°C, the sensor unit will re-detect whether the temperature meets the storage conditions. If the temperature is between 5°C and 40°C, the air conditioner enters the constant temperature mode and proceeds to step S4106; if the temperature still fails to reach 5°C, proceed to step S4103;

[0049] S4105, when the temperature is higher than 40℃, start the air conditioner to cool down:

[0050] When the sensor unit detects that the temperature is higher than 40°C, the control unit will control the air conditioner to start the cooling mode and adjust the indoor temperature for a cooling time of T2. After T2, the sensor unit detects the temperature again. If the temperature drops below 40°C, the process goes to step S4106.

[0051] S4106, constant temperature control:

[0052] When the temperature is between 5℃-40℃, the control unit will adjust the operating state of the air conditioner to ensure that the ambient temperature is maintained within this range and enter the constant temperature mode; the sensor unit will regularly check whether the temperature is within this range. If there is a fluctuation, the air conditioner will make appropriate adjustments to prevent the temperature from deviating from the set range;

[0053] S4107, Humidity determination:

[0054] While controlling the temperature, the sensor unit also needs to monitor the humidity in real time. If the humidity exceeds 80%, it will go to S4108; if the humidity does not exceed 80%, it will maintain the current humidity state;

[0055] S4108, humidity control operation:

[0056] If the humidity exceeds 80%, the control unit will control the air conditioner to start the dehumidification mode for a dehumidification time of T3. After T3, the sensor unit will detect the humidity again to ensure that the humidity drops below 80%.

[0057] The beneficial effects of the present invention are:

[0058] 1. Compared with the prior art, the gasket production process of the present invention covers the whole process from raw material procurement to finished product delivery; firstly, the strict raw material procurement and inspection process can effectively ensure the quality of the raw materials and ensure the smooth progress of the subsequent production process; through the inspection of appearance, size and material, the quality defects caused by raw material problems are reduced; the storage environment of the materials strictly controls the temperature and humidity to ensure that the raw materials are stored in the optimal state to avoid adverse effects on the quality of the materials due to environmental changes; in addition, multiple inspection methods are adopted, such as appearance and size inspection after stamping, and ROHS directive inspection and salt spray test after surface treatment, to ensure that the final product not only meets the size and appearance requirements, but also has corrosion resistance, environmental protection and other properties; the whole set of process flow ensures that the produced gaskets have high quality standards, and through perfect record and tracking management, it can also timely feedback problems and make improvements to ensure the balance between production efficiency and product quality.

[0059] 2. In the present invention, the dimensional accuracy of raw materials can be effectively ensured, and deviations in subsequent processing due to unqualified dimensions can be avoided, thereby affecting the quality and performance of the finished product. Through precise dimensional control, rework and waste can be reduced in the production process, reducing production costs and improving production efficiency. In addition, strict dimensional inspection helps to improve the reliability of finished products, especially in application scenarios with high precision requirements. This control standard can ensure that key indicators such as the sealing performance and durability of the gasket meet industry requirements, thereby enhancing the market competitiveness of the product.

[0060] 3. In the present invention, the temperature is maintained between 5°C and 40°C, and the humidity does not exceed 80%. This control measure is crucial for the long-term preservation of raw materials and finished products. The appropriate range of temperature and humidity can effectively prevent the material from getting damp, deforming, or other quality problems caused by improper environment. For example, too high humidity will cause the material to absorb moisture, expand, or rust, affecting the dimensional accuracy and functionality of the product. Too low temperature may cause the material to become brittle, and too high temperature may reduce the physical properties of the material. By precisely controlling the temperature and humidity, not only the quality of the raw materials used in the production process is ensured to remain stable, but also the quality reliability of the finished product is effectively improved.

[0061] 4. In the present invention, the detection method of the detection module greatly improves the stability and reliability of the storage environment. Through real-time monitoring and automatic adjustment system, timely measures can be taken to adjust when it is found that the temperature or humidity exceeds the set range, ensuring that the storage environment is always in a suitable state. This automated control method not only reduces the errors of manual operation, but also improves the efficiency and accuracy of storage management. Especially in the storage process of raw materials and finished products, changes in temperature and humidity have a profound impact on the performance and quality of materials. Through this intelligent control system, the negative impact of environmental changes on product quality can be effectively avoided, and the optimal state of raw materials and finished products during storage is guaranteed, thereby improving the quality stability of the overall production process and reducing losses and rework caused by environmental problems. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] Figure 1 The figure is a flow chart of the gasket production process of the present invention. DETAILED DESCRIPTION

[0063] Reference Figure 1 The gasket production process embodiment of the present invention is further described.

[0064] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0065] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

During the outbound delivery process, the loading process should be supervised throughout to prevent the products from being damaged or dropped due to improper transportation.

[0098] Compared with the prior art, the gasket production process of the present invention covers the entire process from raw material procurement to finished product delivery; first, the strict raw material procurement and inspection process can effectively ensure the quality of the raw materials and ensure the smooth progress of subsequent production processes; through inspections on appearance, size, material, etc., quality defects caused by raw material problems are reduced; the storage environment of the materials strictly controls temperature and humidity to ensure that the raw materials are stored in the optimal state to avoid adverse effects on material quality due to environmental changes; in addition, multiple inspection methods are adopted, such as appearance and size inspection after stamping, and ROHS directive inspection and salt spray test after surface treatment, to ensure that the final product not only meets the size and appearance requirements, but also has corrosion resistance, environmental protection and other properties; the entire process ensures that the produced gaskets have high quality standards, and through perfect record and tracking management, problems can be fed back in time and improvements can be made to ensure a balance between production efficiency and product quality.

[0099] In S22, the tolerance requirements include a width tolerance of -0.2 mm and a thickness tolerance of ±0.03 mm;

[0100] This standard can effectively ensure the dimensional accuracy of raw materials and avoid deviations in subsequent processing due to unqualified dimensions, which will affect the quality and performance of the finished product. Through fine dimensional control, rework and scrap can be reduced during the production process, reducing production costs and improving production efficiency. In addition, strict dimensional inspection helps to improve the reliability of finished products, especially in application scenarios with high precision requirements. This control standard can ensure that key indicators such as gasket sealing performance and durability meet industry requirements, thereby enhancing the market competitiveness of the product.

[0101] In S4 and S10, the storage temperature and humidity requirements are that the temperature is maintained between 5°C and 40°C, and the humidity does not exceed 80%;

[0102] This control measure is essential for the long-term preservation of raw materials and finished products; the appropriate range of temperature and humidity can effectively prevent materials from getting damp, deforming or other quality problems caused by improper environment; for example, too high humidity will cause the material to absorb moisture, expand or rust, affecting the dimensional accuracy and functionality of the product, too low temperature may cause the material to become brittle, and too high temperature may cause the physical properties of the material to deteriorate. By precisely controlling temperature and humidity, not only is the quality of the raw materials used in the production process ensured to remain stable, but the quality reliability of the finished product is also effectively improved.

[0103] In the S52 and S82, the size requirement is 3.7 mm ± 0.2 mm;

[0104] This size requirement is a strict control of the key quality indicators in the gasket production process. By accurately controlling the size of the finished product after stamping, it can ensure that the finished product has good adaptability during subsequent use and meet the customer's requirements for product size accuracy. The size of the gasket has a direct impact on adaptability, especially in industrial equipment. A gasket that is too large may not fit, and a gasket that is too small may cause safety hazards. Therefore, precise size control not only improves the quality of the finished product, but also enhances the market competitiveness of the product, reduces the rework rate and customer complaints caused by unqualified dimensions, and ensures customer satisfaction and long-term product use.

[0105] In S4 and S10, the detection module includes a sensor unit for real-time monitoring of temperature and humidity and a control unit for receiving data from the sensor unit and controlling the operating state of the air conditioner according to the data results. The detection method includes:

[0106] S4101, sensor unit monitors temperature and humidity in real time:

[0107] In the storage environment, the sensor unit monitors the temperature and humidity of the current environment in real time and transmits the data to the control unit, which makes judgments based on the temperature and humidity data;

[0109] When the sensor unit detects that the current temperature is lower than 5°C, it goes to S4103; if the temperature is between 5°C and 40°C, the control unit goes to S4106; if the temperature is higher than 40°C, it goes to S4105;

[0110] S4103, when the temperature is lower than 5℃, start the air conditioning heating:

[0111] When the temperature value is lower than 5°C, the control unit will control the air conditioner to start the heating mode and adjust the indoor temperature for a heating time of T1. After T1, the sensor unit detects the temperature again. If the temperature reaches above 5°C, the process goes to step S4104.

[0112] S4104, when the temperature reaches 5℃ or above, determine the temperature range:

[0113] During the heating process of the air conditioner, when the temperature rises to 5°C, the sensor unit will re-detect whether the temperature meets the storage conditions. If the temperature is between 5°C and 40°C, the air conditioner enters the constant temperature mode and proceeds to step S4106; if the temperature still fails to reach 5°C, proceed to step S4103;

[0114] S4105, when the temperature is higher than 40℃, start the air conditioner to cool down:

[0115] When the sensor unit detects that the temperature is higher than 40°C, the control unit will control the air conditioner to start the cooling mode and adjust the indoor temperature for a cooling time of T2. After T2, the sensor unit detects the temperature again. If the temperature drops below 40°C, the process goes to step S4106.

[0116] S4106, constant temperature control:

[0117] When the temperature is between 5℃-40℃, the control unit will adjust the operating state of the air conditioner to ensure that the ambient temperature is maintained within this range and enter the constant temperature mode; the sensor unit will regularly check whether the temperature is within this range. If there is a fluctuation, the air conditioner will make appropriate adjustments to prevent the temperature from deviating from the set range;

[0118] S4107, Humidity determination:

[0119] While controlling the temperature, the sensor unit also needs to monitor the humidity in real time. If the humidity exceeds 80%, it will go to S4108; if the humidity does not exceed 80%, it will maintain the current humidity state;

[0120] S4108, humidity control operation:

[0121] If the humidity exceeds 80%, the control unit will control the air conditioner to start the dehumidification mode for a dehumidification time of T3. After T3, the sensor unit will detect the humidity again to ensure that the humidity drops below 80%.

[0122] This technical solution greatly improves the stability and reliability of the storage environment. Through real-time monitoring and automatic adjustment systems, timely measures can be taken to adjust the temperature or humidity when it is found that it exceeds the set range, ensuring that the storage environment is always in a suitable state. This automated control method not only reduces the errors of manual operation, but also improves the efficiency and accuracy of storage management. Especially in the storage process of raw materials and finished products, changes in temperature and humidity have a profound impact on the performance and quality of materials. Through this intelligent control system, the negative impact of environmental changes on product quality can be effectively avoided, and the optimal state of raw materials and finished products during storage is guaranteed, thereby improving the quality stability of the overall production process and reducing losses and rework caused by environmental problems.

The inspection frequency is once a year; S74, Salt spray test: The finished products are subjected to salt spray test by using a salt spray test machine to ensure that there is no blackening or rust within 24 hours. The inspection frequency is 5 per batch; For unqualified products, rework or scrap them in time and record the test results; S8, Finished product inspection: After the surface treatment is qualified, the finished product will enter the final inspection stage, including: S81. Appearance inspection: Ensure that the finished product has a smooth and flat appearance, no burrs, and no mixing of materials; S82, Dimension inspection: Use a vernier caliper to inspect the dimensions of the finished products one by one to ensure that they meet the dimensional requirements; S83. Inspection records are recorded through the finished product inspection record sheet; S9, Packaging and Warehousing: When the finished product passes the inspection, it will be packaged, including: S91. Packaging requirements: Ensure that the packaging is flat, undamaged, and meets transportation and storage requirements; S92, Warehouse management: After packaging, qualified finished products will be sent to the finished product warehouse via pallets or carts; S10. Finished product storage: Packaged finished products should be stored in a finished product warehouse with controlled environment. A thermometer and hygrometer should be used to monitor the storage environment in real time to ensure that the storage temperature and humidity meet the requirements. At the same time, a detection module should be set up for real-time monitoring. Once the storage environment temperature or humidity is abnormal, the system will automatically start the air conditioner to adjust it to ensure that the material storage environment always meets the requirements. The data should be recorded in real time, and the temperature and humidity record sheet should be checked and filed daily. S11. Outbound delivery and distribution: When finished products need to be shipped out, operators will confirm the finished products by checking with the shipping order. After ensuring that they are correct, they will be sent out of the warehouse by cart or pallet. During the outbound delivery process, the loading process should be supervised throughout to prevent the products from being damaged or dropped due to improper transportation.

2. A gasket production process according to claim 1, characterized in that: In S22, the tolerance requirements include a width tolerance of -0.2 mm and a thickness tolerance of ±0.03 mm.

3. A gasket production process according to claim 1, characterized in that: In S4 and S10, the storage temperature and humidity are required to be maintained between 5° C. and 40° C., and the humidity is not more than 80%.

4. A gasket production process according to claim 1, characterized in that: In the S52 and S82, the size requirement is 3.7 mm ± 0.2 mm.

5. A gasket production process according to claim 1, characterized in that: In S4 and S10, the detection module includes a sensor unit for real-time monitoring of temperature and humidity and a control unit for receiving data from the sensor unit and controlling the operating state of the air conditioner according to the data results. The detection method includes: S4101, sensor unit monitors temperature and humidity in real time: In the storage environment, the sensor unit monitors the temperature and humidity of the current environment in real time and transmits the data to the control unit, which makes judgments based on the temperature and humidity data; S4102, temperature judgment: When the sensor unit detects that the current temperature is lower than 5°C, it goes to S4103; if the temperature is between 5°C and 40°C, the control unit goes to S4106; if the temperature is higher than 40°C, it goes to S4105; S4103, when the temperature is lower than 5℃, start the air conditioning heating: When the temperature value is lower than 5°C, the control unit will control the air conditioner to start the heating mode and adjust the indoor temperature for a heating time of T1. After T1, the sensor unit detects the temperature again. If the temperature reaches above 5°C, the process goes to step S4104. S4104, when the temperature reaches 5℃ or above, determine the temperature range: During the heating process of the air conditioner, when the temperature rises to 5°C, the sensor unit will re-detect whether the temperature meets the storage conditions. If the temperature is between 5°C and 40°C, the air conditioner enters the constant temperature mode and proceeds to step S4106; if the temperature still fails to reach 5°C, proceed to step S4103; S4105, when the temperature is higher than 40℃, start the air conditioner to cool down: When the sensor unit detects that the temperature is higher than 40°C, the control unit will control the air conditioner to start the cooling mode and adjust the indoor temperature for a cooling time of T2. After T2, the sensor unit detects the temperature again. If the temperature drops below 40°C, the process goes to step S4106. S4106, constant temperature control: When the temperature is between 5℃-40℃, the control unit will adjust the operating state of the air conditioner to ensure that the ambient temperature is maintained within this range and enter the constant temperature mode; the sensor unit will regularly check whether the temperature is within this range. If there is a fluctuation, the air conditioner will make appropriate adjustments to prevent the temperature from deviating from the set range; S4107, Humidity determination: While controlling the temperature, the sensor unit also needs to monitor the humidity in real time. If the humidity exceeds 80%, it will go to S4108; if the humidity does not exceed 80%, it will maintain the current humidity state; S4108, humidity control operation: If the humidity exceeds 80%, the control unit will control the air conditioner to start the dehumidification mode for a dehumidification time of T3. After T3, the sensor unit will detect the humidity again to ensure that the humidity drops below 80%.
