After the depression angle of the visual product 7 is adjusted to a specified position, the locking screw is turned in the opposite direction so that the head of the locking screw moves away from the adapter block 533 and presses the connecting plate 532 to fix the connecting plate 532 to the adapter block 533, thus completing the fixation of the visual product 7.

[0066] Taking the case where the visual product 7 is vertically facing downward for code reading test, and the test sample passes through the visual product 7 from left to right, when the conveying device 2 drives the test sample to move on the annular slide rail 4 at a low speed, the sensing switch 63 can be set directly below the visual product 7; when the conveying device 2 drives the test sample to move on the annular slide rail 4 at a higher speed, the sensing switch 63 can be set to a position slightly to the left of the visual product 7.

[0081] The circular track linear industrial code reading test system provided in this embodiment has a simple structure and adopts an adjustable mounting bracket 5. During the test, the depression angle and position of the visual product 7 can be adjusted according to different test contents or test samples. Compared with on-site testing, multi-angle testing can be achieved. At the same time, the rotation speed of the motor 21 of the circular track linear industrial code reading test system can be adjusted to achieve the adjustment of different moving speeds of the carrier 3. Specifically, by adjusting the parameters on the control panel 67, the carrier 3 can be adjusted to the required speed. In addition, a combined motion mode of a circle and a straight line is adopted to simulate a variety of test environments, thereby achieving rapid testing of test samples by the visual product 7. Compared with manual adjustment, the circular track linear industrial code reading test system provided in this embodiment greatly improves the convenience of testing, and has a high degree of automation, saving labor costs and improving test efficiency.
