Description

Technical Field

[0001] This utility model relates to the field of potting compound testing technology, specifically a polyurethane potting compound finished product testing device. Background Technology

[0002] Potting compound is a material used for the protection, sealing, and insulation of electronic components. It is made by injecting liquid material into the components or modules that need protection, and after curing, it forms a strong protective layer. Common potting compound materials include epoxy resin, polyurethane, and silicone. Its main functions are to provide insulation, moisture protection, shock protection, and corrosion protection.

[0003] To ensure the quality and performance of potting compounds, a series of tests are required. The shrinkage rate test of polyurethane electronic potting compounds is an important part of evaluating their performance. Shrinkage rate refers to the dimensional reduction phenomenon that occurs in materials due to volume changes during the curing process. For electronic potting compounds, a low shrinkage rate means better dimensional stability and higher reliability.

[0004] The current practice for testing the shrinkage rate of polyurethane electronic potting compound is to manually measure the dimensions of the cured potting compound using measuring tools and compare them with the dimensions before curing. Manual measurement is highly subjective, has a high error rate, is time-consuming and labor-intensive, and has low testing efficiency. Utility Model Content

A bracket 2 is installed on one side of the drying oven 1. A host computer 3 and an industrial camera 4 are respectively installed on the bracket 2, and the industrial camera 4 is electrically connected to the host computer 3. The potting compound is uniformly coated on a test mold 15. The test mold 15 is placed in the drying oven 1 for constant temperature heating and curing. After curing, the industrial camera 4 is activated to collect images of the target object and extract the outline of the object, which is then transmitted to the host computer 3 for analysis and measurement. The data is displayed in real time on the screen of the host computer 3 and compared with the dimensions before curing. The shrinkage rate of the potting compound is calculated by calculating the difference between the two. The device has a high degree of automation, which helps to improve the product testing efficiency and achieve the effect of saving time and manpower.

[0021] The drying oven 1 includes a body 11, a temperature controller 12, a high-temperature resistant glass door 13, an infrared heating tube 14, and a test mold 15. The body 11 is divided into an electrical chamber 16 and a drying chamber 17. The top of the drying chamber 17 is fitted with a high-temperature resistant glass window 18. The temperature controller 12 is fitted into the front of the electrical chamber 16. The high-temperature resistant glass door 13 is hinged to the front of the drying chamber 17. The infrared heating tube 14 is installed inside the drying chamber 17 and is electrically connected to the temperature controller 12. The test mold 15 is placed inside the drying chamber 17.

[0022] Specifically, the drying oven 1 has a slot 19 on one side, and the bracket 2 is inserted into the slot 19.

[0023] In this embodiment, slot 19 is an assembly structure used for the installation and fixation of bracket 2.

[0024] Specifically, the industrial camera 4 is located directly below the high-temperature resistant glass window 18, with its lens facing downwards.

[0025] In this implementation scheme, the industrial camera 4 plays a crucial role in industrial production. Its main functions include improving production efficiency, reducing costs, ensuring product quality, and realizing intelligent manufacturing. The industrial camera 4 is the core component of the machine vision system. It can convert light signals into ordered electrical signals and then into digital signals through an analog-to-digital converter (ADC). Finally, it outputs a standard video signal, which can be used for high-precision product quality inspection, such as defect detection, size measurement, and deviation analysis. The industrial camera 4 acquires images of the target object through the high-temperature resistant glass window 18.

[0026] Specifically, a heat insulation board 110 is attached inside the electrical chamber 16, and the heat insulation board 110 is located on the side wall adjacent to the electrical chamber 16 and the drying chamber 17.

[0027] In this embodiment, the heat insulation board 110 can effectively reduce the transfer of radiant heat flow and protect the components inside the electrical room 16.

[0028] Specifically, one side wall of the electrical chamber 16 is provided with heat dissipation holes 111, and one side wall of the drying chamber 17 is provided with exhaust holes 112.

[0029] In this embodiment, the heat dissipation hole 111 can transfer the heat generated by the components to the external environment, thereby extending the service life of the equipment.

[0030] Specifically, the drying chamber 17 is provided with a placement rack 113, the test mold 15 is placed on the placement rack 113, and the infrared heating tube 14 is located above the test mold 15.

[0031] In this embodiment, the placement rack 113 is used to place the test mold 15, which is a carrier for testing the shrinkage rate of polyurethane electronic potting compound.

[0032] During use, the potting compound is evenly applied to the test mold 15. The test mold 15 is then placed in the drying oven 1 for constant-temperature heating and curing (the infrared heating tube 14 heats the object by radiating infrared energy; the temperature controller 12 is a series of automatic control elements that generate a conduction or disconnection action based on changes in the ambient temperature, resulting in physical deformation inside the switch; by sampling and monitoring the ambient temperature in real time, the device automatically starts or stops when the temperature is higher or lower than the set value to maintain the target temperature). After curing, the industrial camera 4 is activated to acquire images of the target object. The acquired images undergo preprocessing, such as noise reduction and contrast enhancement, and then... The system uses feature extraction algorithms (such as edge detection and shape recognition) to analyze important information in images and transmits it to the host computer 3 (a computer that can directly issue control commands, usually an industrial control computer, PC, or touch screen, which displays various signal changes on the screen. It can process data collected from the industrial camera 4, perform complex calculations, storage and display, and interact with other systems) for analysis and measurement. The host computer 3 (using the RK3566 core board) displays the data in real time and compares it with the dimensions before curing. The shrinkage rate of the potting compound is calculated by calculating the difference between the two. The system has a high degree of automation, which helps to improve the product inspection efficiency and achieve the effect of saving time and manpower.

[0033] In summary, this polyurethane potting compound finished product testing device uniformly coats the potting compound onto the test mold 15, places the test mold 15 into the drying oven 1 for constant temperature heating and curing. After curing, the industrial camera 4 is activated to acquire images of the target object and extracts the object's outline, which is then transmitted to the host computer 3 for analysis and measurement. The host computer 3 displays the data in real time on its screen and compares it with the dimensions before curing. The shrinkage rate of the potting compound is calculated by the difference between the two dimensions. This device has a high degree of automation, which helps improve product testing efficiency and achieves the effect of saving time and manpower.
