Description

Technical Field

[0001] The present invention relates to the technical field of lens testing, and particularly to a wear resistance test device for vehicle-mounted camera lenses. Background Technique

[0002] At present, with the booming development of intelligent driving technology, vehicle-mounted cameras, as key components for vehicles to perceive the external environment, are of great importance. Vehicle-mounted camera lenses are exposed to complex driving environments for a long time. They not only have to face the impact of sand and gravel and the washing of rainwater during high-speed driving, but also bear the influence of different temperature and humidity conditions. Therefore, the wear resistance of the lens becomes the core factor determining its service life and imaging quality.

[0003] Currently, there are many defects in the test devices for the wear resistance of vehicle-mounted camera lenses on the market. On the one hand, the automation degree of most devices is relatively low. In the feeding process, it often relies on manual placement of lenses one by one at the test positions. This is not only inefficient but also difficult to ensure the accuracy of the placement positions, thus affecting the consistency of test results. For example, in some traditional test devices, operators need to manually adjust the lens angles to simulate different usage scenarios, which not only consumes a large amount of manpower but also reduces the reliability of test data due to the angle deviation caused by human factors. After the detection, the sorting of qualified and unqualified products mainly relies on manual judgment and classification, which is not only prone to misjudgment but also severely restricts the improvement of production efficiency.

[0004] On the other hand, there are obvious deficiencies in the test dimensions of existing test devices. Most of them can only perform simple linear reciprocating friction tests and cannot comprehensively simulate the complex friction conditions suffered by vehicle-mounted camera lenses during actual use. For example, the bumps during vehicle driving will cause the lens to be impacted from different angles, and it is very difficult for existing test devices to achieve multi-angle inclined friction tests. In addition, for vehicle-mounted camera lenses of different models and specifications, such as flat lenses and dome lenses, existing test devices lack good adaptability and often require replacing special tooling and test components for different lenses, which undoubtedly increases the test cost and time cost.

The force application rod 50 can move left and right, forward and backward, and rotate for testing the movement tracks in different directions.

[0040] The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0041] S1. The equipment is stably placed through the base 1. After the equipment is powered on, according to actual needs, it can be cooperated with existing production equipment or manually. The lenses to be detected are sequentially erected and placed on the first conveyor belt main body 21 in the conveying unit 2 and are conveyed to the right by the first conveyor belt main body 21.

[0042] S2. When the first conveyor belt main body 21 drives the lens to move to the rightmost end, the guiding and fixing unit 34 in the lens fixing structure 3 can be driven, and the picking units 35 are respectively driven to move alternately back and forth through the guiding and fixing unit 34 to pick up the lenses on the first conveyor belt main body 21 respectively.

[0043] S3. When one of the picking units 35 moves along the conveying groove 6 on the conveying table 32 supported by the support frame 31 with the aid of the guiding and fixing unit 34, the clamping arm 356 is located inside the right end of the first conveyor belt main body 21, and the second electric slide rail 355 is driven to make the clamping arm 356 move relatively to clamp one lens or arrange multiple lenses;

[0044] Then, as the first electric slide rail 341 drives the rotating shaft 343 to move from the left end to the right end of the conveying groove 6, since the rectangular rod part in the middle of the rotating shaft 343 is located inside the limiting frame 342 and cannot be forced to rotate due to the limitation of the limiting frame 342, it is limited and translated to the right;

[0045] When the rotating shaft 343 disengages from the limiting frame 342 at the left end, the gear 344 on the rotating shaft 343 will contact the corresponding rack 345 to form relative movement, and then the gear 344 is forced to engage and rotate 180 degrees along the teeth of the rack 345, so that the clamping arm 356 of the picking unit 35 can be rotated from being opposite to the first conveying unit 2 main body to being opposite to the second conveyor belt main body 22, and the middle part of the rotating shaft 343 enters the limiting frame 342 located at the right end of the conveying table 32 again for limiting;

[0046] S4. After the picking unit 35 drives the lens to the right end of the conveying table 32, by virtue of the length of the clamping arm 356, the lens is located above the left end of the second conveyor belt main body 22, and then the camera 47 in the testing structure 4 irradiates and forms an image to realize the determination of its front and back based on visual detection. If the glass front of the lens is opposite to the camera 47, the force-applying rod 50 can be directly driven to conduct the abrasion resistance test; if the glass lens is not aligned with the camera 47, the first motor 354 on the shaft frame 352 drives the shaft tube 353 to rotate. The shaft tube 353 is located on the shaft frame 352 to carry the second electric slide rail 355 and drive the second electric slide rail 355 to rotate, so as to turn the lens over above the picking seat 351;

[0047] S5. Then, after determining the front and back and position of the detected lens, the cross-shaped slide rail 42 on the overhead rack 41 can be driven to drive the carrying arm 43 to move left and right and move forward and backward to calibrate the position of the force-applying rod 50, and the hydraulic cylinder 44 is driven to extend to drive the chassis 45 to descend with the lifting rod 46, so that the force-applying rod 50 descends to contact the lens;

[0048] After the force - applying rod 50 contacts the lens, the turntable 49 can be driven by the second motor 48. The force - applying rod 50 is fixed at the jack 7 of the turntable 49 by means of the fastening bolt 8, and its position is eccentrically installed. Therefore, when the second motor 48 drives the turntable 49 to rotate, it drives the force - applying rod 50 to rotate in a circle. The movement track generated by the contact between the force - applying rod 50 and the lens is circular or reciprocating. Driving the second motor 48 can also realize the arc - shaped movement of the force - applying rod 50 to test the wear resistance of the lens. The cross - shaped slide rail 42 can also be used to drive the force - applying rod 50 to move left - right and front - back on the lens for wear - resistance testing. And according to the actual test requirements, the material of the force - applying rod 50 and the shape of the end part, such as arc - shaped, conical, etc., can be set to conduct wear - resistance testing along different movement tracks and different contact surfaces. Moreover, since the glass of the lens may be flat or arched, in order to improve the test effect and fit the movement - track test, during the lens test, the first motor 354 can also be used to drive the clamping arm 356 and the lens to be flipped at different angles for inclined - force testing;

[0049] After the test, whether the wear resistance of the lens meets the production requirements can also be determined by means of the flipping angle of the lens and imaging the lens from different angles through the camera 47 to determine whether there are abrasions, scratches, etc.;

[0050] When the test of the lens meets the production specifications, the lens is placed on the left end of the second conveyor belt main body 22 through the clamping arm 356, conveyed to the right through the second conveyor belt main body 22, and centered and converged by the relatively arranged converging arms 23 and then flows into the receiving box 24 for waiting to be processed;

[0051] When the lens test is unqualified, when driving the two guiding and fixing units 34 alternately, that is, when the picking unit 35 clamping the lens moves from right to left, the rotating shaft 343 will contact and rotate with the rack 345 again by means of the gear 344. When the rotating shaft 343 rotates 90 degrees, the clamping arm 356 is located above the corresponding waste chute 33. At this time, the clamping arm 356 can be loosened to drop the unqualified product into the waste chute 33 to achieve differentiated blanking;

[0052] When the picking unit 35 in the above S9 moves from right to left after detection, the other picking unit 35 operates in the same way as above. After picking and clamping the lens from the left side of the guiding table 32, it performs right - translation, flipping, translation, and detection and determination processes to achieve double - station alternation and improve efficiency.

[0053] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
