Technical Field

[0001] This utility model relates to the field of PVB interlayer film detection technology, specifically to a user-friendly PVB interlayer film transmittance detection device. Background Technology

[0002] PVB interlayer is a high-performance polymer functional material widely used in the field of laminated glass. It plays a key role in many industries such as construction, automobiles, photovoltaics, and aerospace. After the PVB interlayer is processed and produced, its light transmittance needs to be tested to remove unqualified products.

[0003] Existing PVB interlayer transmittance testing devices, such as the easy-to-use PVB interlayer transmittance testing device disclosed in publication number CN210221819U, have the advantage of clamping the PVB interlayer to be tested without manual clamping. However, it is inconvenient to clean the dust from both ends of the clamped PVB interlayer, and it is also inconvenient to shield the detector and light source inside the testing device from dust when not in use. Therefore, we propose an easy-to-use PVB interlayer transmittance testing device. Utility Model Content

[0028] Specifically, PVB interlayer is a high-performance polymer functional material widely used in laminated glass. After processing and production, the light transmittance of the PVB interlayer needs to be tested to reject unqualified products. The dust suction heads 204 located at the top and bottom of the pressing frame 203 and support frame 202 within the testing chamber 100 can perform dust suction on the top and bottom surfaces of the PVB interlayer sandwiched between the pressing frame 203 and support frame 202, preventing dust residue from affecting the testing accuracy. Simultaneously, the protective pad 205 at the outer end of the dust suction head 204... The openings of the unused detection head 209 and light source 210 inside the detection box 100 can also be sealed during vacuuming to prevent dust from accumulating inside the detection head 209 and light source 210 and affecting detection accuracy. When the detection box 100 is not in use, the protective pad 205 at the outer end of the vacuum head 204 can also cover the detection head 209 and light source 210 to block dust and debris. The support strips 212 and pressing strips 214 arranged at both ends of the inner side of the support frame 202 and the pressing frame 203 can also make the PVB sandwiched between the support frame 202 and the pressing frame 203... The interlayer membrane can be of different sizes to improve the adaptability of the testing box 100. A small feed inlet 201 on one side of the testing box 100 allows for feeding of the PVB interlayer membrane while reducing dust intrusion. The testing head 209 and light source 210 are located at the upper and lower ends of the center of the pressing frame 203 and the support frame 202. Therefore, the suction head 204 at the outer end of the testing head 209 and the light source 210 can uniformly and comprehensively vacuum the PVB interlayer membrane clamped between the pressing frame 203 and the support frame 202 at the central testing area.

The electric push rod 211 at the upper end of the pressing frame 203 is mainly used to adjust the downward pressure of the pressing frame 203, thereby pressing the PVB intermediate film between the support frame 202 and the pressing frame 203. The baffles 213 on both sides of the rear end of the support frame 202 are mainly used to block the PVB intermediate film feeding position. The exhaust pipe 218 on the vacuum cleaner 207 is mainly used to exhaust the filtered air to the outside of the test box 100. The cleaning of the vacuum cleaner 207 can be completed by opening the box door 101.

[0029] Working principle and usage process of this utility model:

[0030] During PVB interlayer testing, the PVB interlayer is directly inserted into the feed inlet 201 at the front of the testing chamber 100, moving inward along the inner support frame 202. When the PVB interlayer encounters the obstruction of the rear baffle 213 of the support frame 202, the insertion stops, and the electric push rod 211 is activated to drive the pressing frame 203 downward, pressing the PVB interlayer between the support frame 202 and the pressing frame 203. After the PVB interlayer is pressed and fixed, the vacuum cleaner 207 inside the testing chamber 100 is activated, using the suction head 206 connected to the upper and lower ends of the PVB interlayer via the suction pipe 206 on one side of the vacuum cleaner 207. 04. Perform a thorough dust removal process on the upper and lower ends of the central detection area of ​​the PVB interlayer to clean away any residual dust. After the PVB interlayer is cleaned, activate the electric slide rail 208 to move the vacuum cleaner 207 and vacuum head 204 together via the bottom slider 216. After the upper and lower vacuum heads 204 have moved outward, their outer protective pads 205 will also move outward to remove the outer ends of the detection head 209 and the light source 210, thus releasing the obstruction of the detection head 209 and the light source 210, and activating the detection head 209 and the light source 210 to perform detection processing on the PVB interlayer.
