[0027] See Figures 1 - 3 , a polyethylene fish-eye detection light-transmitting device, comprising: a housing 1, an opening is provided at the top of the housing 1, which is made of a plastic material with relatively high hardness, lightweight and having a certain strength. The size of the housing 1 is 34 cm × 25 cm × 13 cm. The housing is trapezoidal in structure when viewed from the side, and the large end faces upward; a colorless glass 2 with good light transmittance is placed on the top of the housing 1.

[0028] Aluminum foil plates 6 are laid on the bottom and the inner periphery of the housing 1 for reflecting and diverging the light, making the light more uniform and not dazzling; a light source 3 is installed on the surface of the aluminum foil plate 6. The light source 3 is an LED light strip with a length of 220 cm, which winds around the aluminum foil plate 6 on the four walls of the housing 1 for two weeks and is fixed by a second fixing clip 7. The second fixing clip 7 can be of a U-shaped structure, and both ends can be bonded to the aluminum foil plate 6 to clamp the LED light strip inside the second fixing clip 7; the LED light strip is made of transparent PVC material, with 60 lamp beads per meter, white light of 6000K - 6700K. The attached plug and switch of the LED light strip are led out of the housing 1 for controlling the power supply. The application of the LED light strip makes the light source evenly distributed on the four walls of the box body, and in cooperation with the aluminum foil plate, a light-transmitting device with uniform, stable and non-dazzling light is formed.

[0029] A positioning photo frame 4 is placed on the colorless glass 2 of the housing 1. The positioning photo frame 4 is made of an opaque plastic plate. The outer edge size of the positioning photo frame 4 is 310 mm × 240 mm, which just covers the colorless glass 2. An observation area 5 of 190 mm × 200 mm is cut out in the middle of the positioning photo frame 4 for film inspection. A first fixing clip 8 is installed on the top of the positioning photo frame 4. The structure of the first fixing clip 8 can be that of a metal spring clip of a file folder, and the film is fixed by the first fixing clip 8 during detection.

[0030] In use, place the film on the observation area 5 and fix it with the first fixing clip 8. Turn on the LED light strip. The outer shell 1 serves as a light-transmitting device. The aluminum foil plates laid around the inner periphery and at the bottom of the outer shell 1 reflect and diverge light. When observing from top to bottom and using a magnifying glass with scales in combination, the size of the fish eyes can be accurately measured, making the inspection work fast and accurate.

[0031] It should be noted that compared with the traditional method of using a pen to draw a frame (190mm×200mm) and using a fluorescent lamp as the detection light source, in this utility model, the film is directly fixed in the positioning photo frame, saving the workload of drawing the frame, and the light is more uniform and stable; the operation changes from looking up to looking down, making it easier to observe and mark the fish eyes on the film sample, and realizing the combined use with a magnifying glass with scales, which can more accurately determine the size of the fish eyes, thus ensuring the accuracy of the detection data. Especially for samples where the size of the fish eyes is close to the target value, its advantages and effects are more obvious.

[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
