Description

TECHNICAL FIELD

[0001] The utility model relates to a light transmittance detection device technical field, specifically a light transmittance detection device for automobile. BACKGROUND

[0002] The working principle of the light transmittance detection device for automobile is based on optical measurement technology. The light emitted by the light source is uniformly irradiated to the automobile parts (such as glass or solar film) to be measured through the optical system, and the transmitted light is received by the light receiver (such as photodiode or photocell) and converted into an electrical signal. After amplification and filtering processing, the electrical signal is sent into the signal processor for data processing and analysis, and finally the light transmittance value is obtained and output through the electronic display device (such as LCD display screen or printer).

[0003] When detecting the light transmittance of automobile parts, workers usually hold the detection device to detect each point of the automobile parts in turn, but the workers have high labor intensity during operation, which can cause arm numbness and make it impossible to continuously detect for a long time. Therefore, the detection efficiency of this detection method is low, and the moving track of the detection instrument is controlled by the workers, so that the omission of local points is inevitable, which leads to incomplete detection of the entire part and may cause defective products to pass the detection. Therefore, the light transmittance detection device for automobile is proposed to solve the above problems. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide a light transmittance detection device for automobile. The light transmittance detection device comprises a transmitter and a receiver to form a detection unit, which completes the light transmittance detection of the automobile parts placed therebetween. During work, the screw rod driving mechanism drives the two horizontal screw rod sliding table mechanisms to operate synchronously, and then drives the transmitter and the receiver to move synchronously, so as to ensure matching work and enable the detection unit to move automatically in the horizontal direction. In addition, the longitudinal driving mechanism can drive the sliding base to displace longitudinally during operation, so that the detection unit can move automatically in the longitudinal direction. Based on the above structure, the detection unit can automatically complete the sequential detection of all points of the entire part through horizontal movement and longitudinal movement, which can reduce the work difficulty of workers and effectively avoid the omission of detection points. The technical problem that the workers cannot continuously detect for a long time due to high labor intensity and the omission of local points during the sequential detection of each point of the automobile parts by the workers holding the detection device is solved.

The light transmittance detection device is composed of the detection unit of the transmitter 71 and the receiver 72, and the light transmittance detection of the automobile parts placed therebetween is completed. In the working process, the screw driving mechanism 6 drives the two horizontal screw sliding table mechanisms 5 to synchronously operate, and then drives the transmitter 71 and the receiver 72 to synchronously move, so as to ensure that the matching work can be realized, and the detection unit can be automatically moved in the horizontal direction. In addition, the longitudinal driving mechanism 3 can drive the sliding base 2 to longitudinally displace in the working process, so that the detection unit can be automatically moved in the longitudinal direction. Based on the above structure, the detection unit can be automatically detected at all points of the whole part through the horizontal movement and the longitudinal movement, the working difficulty of the workers can be reduced, and the omission of the detection points can be effectively avoided.

[0024] As shown in the figure, Figure 3 The bottom of the guide cylinder shell 51 is provided with a second sliding groove 512, and a mounting plate 55 is slidably arranged in the second sliding groove 512. The upper end of the mounting plate 55 is fixedly connected with the horizontal transmission sliding block 53, and the lower end is bolted with the transmitter 71 and the receiver 72. The above structure can realize the transmission connection between the transmitter 71, the receiver 72 and the horizontal transmission sliding block 53, and the connection mode is detachable connection, which can facilitate the disassembly and replacement of the transmitter 71 and the receiver 72 in the use process.

The guide rail plate 31 has a guide rib 35 fixedly disposed on its inner wall, and the longitudinal transmission slider 32 has grooves on both sides corresponding to the guide rib 35. The locking effect between the guide rib 35 and the groove can improve the stability of the longitudinal transmission slider 32 during the sliding process and prevent it from deviating during sliding.

In addition, the sliding base 2 can be longitudinally displaced by the longitudinal driving mechanism 3, so that the detection unit can be automatically moved longitudinally. Based on the above structure, the detection unit can be automatically detected at all points of the whole part by the horizontal movement and the longitudinal movement, the operation difficulty of the workers can be reduced, and the omission of the detection points can be effectively avoided.

[0031] When the horizontal movement is needed, the horizontal driving motor 61 is operated to drive the first transmission wheel 62 to rotate, and the second transmission wheel 63 is synchronously rotated under the transmission of the transmission belt 64, so that the emitter 71 and the receiver 72 are synchronously displaced horizontally.

[0032] When the longitudinal movement is needed, the longitudinal driving motor 34 is operated to drive the longitudinal screw rod 33 to rotate, and then the longitudinally transmission slide block 32 connected with the longitudinal screw rod 33 is slid, so that the sliding base 2 can be longitudinally displaced along the longitudinal guide rail base 1.

For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description.
