[0002] An electric control box contains one or more low-voltage switchgears and related control, measurement, signal, protection, regulation and other devices, and is completely assembled together by a manufacturer with structural components. Silicone rubber is used for sealing between various components of the electric control box. Silicone rubber refers to a rubber whose main chain is composed of alternating silicon and oxygen atoms, and usually two organic groups are connected to the silicon atoms. Ordinary silicone rubber is mainly composed of siloxane chain segments containing methyl and a small amount of vinyl.

[0003] When producing silicone rubber seals, if impurities are mixed into them, it may cause protrusions or depressions on the surface of the silicone rubber seals, which may lead to a decrease in their sealing performance and leakage after installation; when producing silicone rubber sealing rings, to ensure their sealing effect, the silicone rubber needs to have sufficient elasticity to be stretched and compressed and generate appropriate resilience to fill the sealing gap, otherwise there may be a situation of poor sealing and leakage; due to the particularity of the working environment of ships, silicone rubber seals need to have a certain degree of corrosion resistance.

A fixing mechanism 29 for fixing the roller 23 is provided on the slide plate 22. It should be noted that the fixing mechanism 29 includes a return-shaped fixing plate 30 slidably sleeved outside the slide plate 22. It should be noted that the friction between the slide plate 22 and the return-shaped fixing plate 30 is relatively large. A card plate 31 is installed on the return-shaped fixing plate 30.

The U-shaped fixed plate 30 drives the clamping plate 31 to move until the clamping plate 31 is clamped with the fixed gear 32. Then, drive the two moving screws 54 to move relative to each other through the turning handle 28. The two moving screws 54 drive the two sliding plates 22 to move, and the sliding plates 22 drive the roller shaft 23 to move until the roller shaft 23 clamps and fixes the silicone rubber. When adjusting the position of the silicone rubber seal, push the U-shaped fixed plate 30 so that the clamping plate 31 does not limit the fixed gear 32. At this time, drive the power shaft 36 to rotate through the driving motor 37, and the power shaft 36 drives the two roller shafts 23 to rotate relative to each other, so as to push the silicone rubber seal and thus adjust its position.

[0032] In order to detect the surface of the silicone rubber seal, a detection mechanism 42 is provided. The detection mechanism 42 includes an arc-shaped plate 55. A camera 43 is installed on the inner wall of the arc-shaped plate 55. A U-shaped plate 44 is slidably installed outside the arc-shaped plate 55.

The main transmission wheel 50 is meshingly connected with the slave transmission wheel 49.

[0033] Through the above technical features: the driving motor 51 drives the connecting shaft 48 to rotate, the connecting shaft 48 drives the arc plate 55 to rotate through the driving gear 47, and the arc plate 55 drives the camera 43 to rotate. Thus, each part of the silicone rubber seal can be inspected by the camera 43 to achieve a comprehensive inspection.

[0034] Working principle: Detection of the environmental tolerance of the silicone rubber seal: the lifting motor 11 drives the lifting screw 8 to rotate, the lifting screw 8 drives the return plate 3 to lift, the return plate 3 drives the fixed plate 5 to lift, and the fixed plate 5 drives the silicone rubber seal to lift until it enters the simulation box 1.

Detection of the resilience of the silicone rubber seal: the stretching motor 18 drives the rotating shaft 14 to rotate, the rotating shaft 14 drives the two threaded sleeves 53 to rotate, the two threaded sleeves 53 drive the two stretching screws 13 to move relatively, and the two stretching screws 13 drive the fixed plate 5 to move through the L-shaped plate 12. The fixed plate 5 drives the silicone rubber seal to stretch through the side plate 20. After stretching for a certain distance and time, the silicone rubber seal is relaxed. When the value of the tension sensor is zero, the distance between the two fixed plates 5 is compared with the initial distance, and the elasticity of the silicone rubber seal can be detected. Fixing and repositioning the silicone rubber seal: when clamping the silicone rubber seal, push the return fixed plate 30, and the return fixed plate 30 drives the clamping plate 31 to move until the clamping plate 31 is clamped with the fixed gear 32. Then drive the two moving screws 54 to move relatively through the turning handle 28, the two moving screws 54 drive the two sliding plates 22 to move, and the sliding plates 22 drive the roller shafts 23 to move until the roller shafts 23 clamp and fix the silicone rubber. When repositioning the silicone rubber seal, push the return fixed plate 30 so that the clamping plate 31 does not limit the fixed gear 32. At this time, drive the power shaft 36 to rotate through the drive motor 37, and the power shaft 36 drives the two roller shafts 23 to rotate relatively, and the silicone rubber seal can be pushed, thereby adjusting its position. Checking whether there are protrusions and depressions on the silicone rubber seal: the driving motor 51 drives the connecting shaft 48 to rotate, the connecting shaft 48 drives the arc plate 55 to rotate through the driving gear 47, and the arc plate 55 drives the camera 43 to rotate. Thus, each part of the silicone rubber seal can be inspected by the camera 43 to achieve a comprehensive inspection.
