Description

Auxiliary assembly for testing intelligent camera and testing system

Technical Field

The utility model mainly relates to the technical field of intelligent cameras, in particular to an auxiliary assembly and a testing system for testing an intelligent camera.

Background

The camera is video acquisition equipment, and the application is extensive, and the function is various. Currently, cameras integrate more functions, and the cameras can be used as cameras and gateway interfaces, and can be used for video monitoring and can also be used as data interfaces of some sensing devices. The intelligent camera can also control the intelligent camera through the mobile phone APP, and the intelligent camera is convenient to use.

Intelligent cameras are also commonly used in automotive applications, such as vehicle cameras. The vehicle-mounted camera is known as an 'autopilot' and is used for realizing image information acquisition through a lens and an image sensor, and more than 80% of autopilot technologies can be applied to the camera or the camera is used as a solution. The data collected by the intelligent camera is processed, analyzed and transmitted to the control center by the AI, and the control center feeds back the data to the automobile or the driver after a certain judgment.

Therefore, the intelligent camera has wide application range and multiple functions, so that the quality requirement is higher and higher. In order to meet higher quality requirements, detection or testing of the intelligent camera is an important ring. In various tests of smart cameras, it is necessary to test the optical performance of the smart camera with a collimator. A collimator is a device for collimating particles and waves, intended for the manufacture and adjustment of optical devices, and producing perfectly parallel rays, i.e. a group of rays that can be regarded as a point source at infinity, for accurately assembling lenses and mirrors that make up an optical system without tilting, and for adjusting the position of the focal point.

For example, when performing a final function test (FFT, final Function Test) on a smart camera (SCAM 4.8), a laser collimator is required, but in the above test process, only one smart camera can be tested by one laser collimator, and after the test of the laser collimator is completed, the laser collimator is in an idle state at other times. Only after all the test work of the smart camera (including other tests except the collimator) is completed, the next smart camera can be tested. Therefore, the one-to-one test mode adopted at present cannot fully utilize the laser collimator, and the laser collimator is expensive equipment, so that the total cost of the intelligent camera test is high.

Referring to fig. 1 to 10, the auxiliary assembly for testing an intelligent camera according to the present embodiment mainly includes: the device comprises at least two transverse moving parts 11, at least two longitudinal moving parts 12 and at least two clamps 13, wherein one longitudinal moving part 12 is connected above each transverse moving part 11 to drive the longitudinal moving parts 12 to transversely move, and one clamp 13 is connected above each longitudinal moving part 12 to drive the clamps 13 to longitudinally move. The overall effect of the auxiliary assembly is to enable the gripper 13 to be moved to the test site of the collimator 44.

In the present embodiment, one lateral movement portion 11, one longitudinal movement portion 12, and one clamp 13 are a set of auxiliary single pieces. According to the necessity, economy and difficulty of the addition of auxiliary components, the auxiliary components

The auxiliary assembly 10 generally has two sets of auxiliary singlets that can be symmetrically positioned 5 about the platform.

In the process of product testing, one auxiliary single piece sends the product to be tested on the clamp 13 to the testing position of the collimator 44 for testing. At this time, the other auxiliary single piece is ready, and after the first auxiliary single piece is tested and withdrawn, the second auxiliary single piece is started to start

The product to be tested thereon is sent to the test site of the collimator 44 for testing. In this way, the collimator 44 is fully utilized by 0, and the idle time of the collimator 44 is reduced.

As shown in fig. 1, the movement of the clamp 13 will be described in detail by taking one set of auxiliary single-piece operation as an example. In the state shown in fig. 1, the test of the collimator 44 is in the upper right of the jig 13. The lateral movement portion 11 is activated, and the longitudinal movement portion 12 thereon can move along the broken line L1

The moving, i.e., the longitudinal moving portion 12 moves in the direction indicated by the arrow of the broken line L1, and the longitudinal moving portion 12 moves 5 to stop at the point a. At this time, the vertically movable section 12 is activated, and the clamp 13 thereon can be moved along

the lateral movement part 11 and the longitudinal movement part 12 can be started sequentially or simultaneously, or can be started under the control of a controller program, and the like, so long as the clamp 13 can be moved to the test position of the collimator 44 through the movement coordination of the lateral movement part 11 and the longitudinal movement part 12.

In general, the conventional test mode is to test one product under test directly at test 5 of collimator 44, and with the auxiliary assembly of this embodiment, two (or more) products under test are tested in need of such

To test its optical performance, the auxiliary assembly 10 is translated to the test site of the collimator 44 for testing, and after the optical performance test is completed, the auxiliary assembly returns to the initial position for testing other functions. Therefore, in a total test process, the number of products to be tested can be two or more, so that the test time of the collimators 44 can be fully utilized, the test efficiency is improved, and the total cost is saved, which is equivalent to saving one or more sets of collimators 44. In addition, the test mode of the product to be tested is error dislocation time test, and the cycle time of the test is not obviously influenced.

In some embodiments, the lateral movement portion 11 may adopt the following structure: the device comprises a transverse driving motor 21, wherein the output end of the transverse driving motor 21 is connected with a transverse screw 22, the transverse screw 22 is provided with a transverse sliding block 23, the transverse sliding block 23 is connected with a longitudinal moving part 12, and the transverse sliding block 23 moves along a transverse sliding rail 24, namely, the rotation of the transverse driving motor 21 is converted into the transverse movement of the transverse sliding block 23 by adopting a screw mode.

As shown in fig. 7, after the transverse driving motor 21 is started, the transverse screw 22 (inside, indicated by a dotted line) connected with the transverse driving motor is driven to rotate, and as the transverse screw 22 is provided with connecting pieces such as nuts, the connecting pieces are fixed with transverse sliding blocks 23, so that the transverse sliding blocks 23 move back and forth along the transverse screw 22, and the longitudinal moving part 12 is fixed on the transverse sliding blocks 23, and finally, the longitudinal moving part 12 moves back and forth along the length direction of the transverse screw 22. Below the lateral slide 22 is a lateral slide 24, the lateral slide 24 supporting the movement of the lateral slide 22.

In some embodiments, the longitudinal moving portion 12 may take the following structure: the device comprises a longitudinal driving motor 31, wherein the output end of the longitudinal driving motor 31 is connected with a longitudinal screw rod 32, the longitudinal screw rod 32 is provided with a longitudinal sliding block 33, the longitudinal sliding block 33 is connected with a clamp 13, and the longitudinal sliding block 33 moves along a longitudinal sliding rail 34, namely, the rotation of the longitudinal driving motor 31 is converted into the longitudinal movement of the longitudinal sliding block 33 by adopting a screw rod mode.

As shown in fig. 8, after the longitudinal driving motor 31 is started, the longitudinal screw rod 32 (inside, indicated by a dotted line) connected with the longitudinal driving motor is driven to rotate, and as the longitudinal screw rod 32 is provided with connecting pieces such as nuts, longitudinal sliding blocks 33 are fixed on the connecting pieces, the longitudinal sliding blocks 33 move back and forth along the longitudinal screw rod 32, and the clamps 13 are fixed on the longitudinal sliding blocks 33, so that the clamps 13 can move back and forth along the length direction of the longitudinal screw rod 32. Below the longitudinal slide 32 is a longitudinal slide 34, the longitudinal slide 34 serving as a support for the movement of the longitudinal slide 32.

In some embodiments, the lateral drive motor 21 and/or the longitudinal drive motor 31 employ a stepper motor. In the present embodiment, in the case of non-overload, the rotation speed of the stepping motor, the position of stop depends only on the frequency and the number of pulses of the pulse signal, and is not affected by load variation. When the step driver receives a pulse signal, it drives the step motor to rotate a fixed angle according to a set direction, and the rotation of the step motor is operated step by step at a fixed angle, so that the moving distance of the longitudinal moving part 12 on the transverse moving part 11 or the moving distance of the clamp 13 on the longitudinal moving part 12 is adjusted by the rotation mode of the step motor, thereby achieving the purpose of accurately moving the position, and the speed and the acceleration of the motor rotation can be controlled by controlling the pulse frequency, thereby achieving the purpose of speed regulation.

In some embodiments, the lateral screw 22 and/or the longitudinal screw 32 employ a ball screw. The screw is generally classified into a sliding screw, a ball screw and a hydrostatic screw. The transmission efficiency of the sliding screw is about 26-46%, the transmission efficiency of the ball screw is about 90-96%, the static pressure screw is complex in structure and high in cost. If the same large load is driven, the ball screw can use smaller driving power, such as a smaller power driving motor, so that the cost and the energy consumption can be reduced. Although the self-locking property of the ball screw is insufficient compared with the other two screws, the position movement of the longitudinal moving portion 12 and the clamp 13 in the present embodiment is in the horizontal plane, so that the use effect of the auxiliary assembly in the present embodiment is not affected even if the self-locking function is not provided, and the transmission efficiency is higher, so that the ball screw can be adopted in the present embodiment.

In some embodiments, a lateral support plate 25 is provided on the lateral slider 23, and a longitudinal moving portion 12 is connected above the lateral support plate 25. The upper surface of the lateral slider 23 is small, and its width is generally equal to that of the lateral slide rail 24, so that it is not preferable to directly fix the longitudinal moving portion 12 on the upper surface thereof, and if the longitudinal moving portion 12 is directly fixed, the load-bearing effect of the lateral slider 23 on the longitudinal moving portion 12 is poor. In this embodiment, a transverse support plate 25 may be fixed on the transverse slider 23, where the transverse support plate 25 has a sufficiently large upper surface, and then the longitudinal moving portion 12 is fixed on the upper surface of the transverse support plate 25, so as to effectively support the longitudinal moving portion 12.

Further, a longitudinal support plate 35 is provided on the longitudinal slider 33, and the jig 13 is attached above the longitudinal support plate 35. The upper surface of the longitudinal slider 33 is small, and its width is generally equal to that of the longitudinal rail 34, so that it is not suitable to directly fix the clamp 13 on its upper surface, and if the clamp 13 is directly fixed, the load-bearing effect of the longitudinal slider 33 on the clamp 13 is poor. In this embodiment, a longitudinal support plate 35 may be fixed on the longitudinal slide 33, the longitudinal support plate 35 has a sufficiently large upper surface, and then the clamp 13 is fixed on the upper surface of the longitudinal support plate 35, so as to effectively support the clamp 13.

In some embodiments, the cross-sectional shape of the transverse rail 24 and/or the longitudinal rail 34 is U-shaped, and the transverse lead screw 22 and/or the longitudinal lead screw 32 are disposed within the corresponding U-shaped rail. Taking the transverse rail 24 shown in fig. 7 as an example, the cross-sectional shape of the transverse rail 24 is U-shaped, that is, the transverse rail 24 is U-shaped at the section M or the position parallel to the section M, and the transverse rail 24 may be referred to as a U-shaped rail. The U-shaped sliding rail has the advantages that firstly, the transverse screw rod 22 can be arranged in the U-shaped sliding rail, the contact of the transverse screw rod 22 with other objects is avoided, the normal operation of the transverse screw rod 22 is affected, and secondly, the transverse sliding rail 24 can support the transverse sliding blocks 23 at two sides, so that the stability of the transverse sliding blocks 23 in the moving process is improved. The relevant structure and effect of the longitudinal rails 34 are not described in detail herein.

In some embodiments, a support seat 41 is fixed to the rear end of the transverse rail 24 and/or the longitudinal rail 34. The function of providing the support seat 41 is: one, may provide an effective support for the rear end of the lateral lead screw 22 and/or the longitudinal lead screw 32; secondly, the whole transverse screw rod 22 and/or the longitudinal screw rod 32 can be located in an enclosed environment, so that the possibility that the transverse screw rod 22 and/or the longitudinal screw rod 32 is in contact with other objects is further reduced, and the normal operation of the transverse screw rod 22 and/or the longitudinal screw rod 32 is ensured.
