Description

Technical Field

[0001] The utility model relates to the technical field of cameras, in particular to a camera sealing test device. Background Art

[0002] When assembling a camera, the shell and the end cap are usually welded together using welding technology. The sealing of the weld is directly related to the sealing of the camera as a whole. The existing airtight fixtures for testing cameras generally wrap the entire camera in a test cavity, then introduce high-pressure gas into the test cavity, and detect the air pressure changes in the test cavity to obtain the leakage value of the camera. First, the camera needs to be placed in the test cavity as a whole. Since the camera contains a wiring harness, the test cavity will be too large, the test time will be too long, the test cost will be high, and the test efficiency will be low. Secondly, if the sealing of the weld is not high, the high-pressure gas will leak into the camera through the weld. After the air pressure inside the camera stabilizes, the leakage value of the camera cannot be truly tested, which seriously affects the accuracy of the test. Utility Model Content

[0003] The purpose of the utility model is to provide a camera sealing test device in view of the above-mentioned deficiencies, which can provide a camera airtightness test device with a small test cavity, short test time and high test accuracy, and proposes the following technical scheme: a camera sealing test device, comprising a lens, the top of the lens is fixedly connected to a shell, the top of the shell is fixedly connected to an end cover through a weld, the top of the end cover is penetrated and fixedly connected with a wiring harness, the lens is arranged in a cylinder, a test air path is penetrated through the right side of the cylinder, the bottom of the cylinder is fixedly connected to a base, the top left end of the base is fixedly connected to a base, the top of the base is fixedly connected to a motor, the motor output shaft is fixedly connected to a moving column, and a fixed grabbing assembly is arranged at the bottom of the moving column.

[0004] As a preferred technical solution of the utility model, the fixed grabbing assembly includes an electric push rod, the bottom of the output end of the electric push rod is fixedly connected to an upper frame, and the outer side of the upper frame is fixedly connected to three upper hinges.

[0005] As a preferred technical solution of the utility model, a connecting plate is fixedly connected to the bottom of the guide rod, three lower hinges are fixedly connected to the outer side of the connecting plate, and the lower hinges are rotatably connected to claws through support rods.

[0007] As a preferred technical solution of the utility model, the angle between the three upper hinges is 120 degrees, and the upper hinges correspond to the lower hinges in a one-to-one vertical direction.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] 1. The utility model provides a camera sealing test device, which can grasp and fix the camera through an electric push rod, an upper frame, an upper hinge, a connecting rod, a lower hinge, a claw and a caliper, and realize the change of position through a motor and a moving column, which can not only reduce the manual labor but also fix the camera and improve the accuracy of detection.

[0010] 2. The utility model provides a camera sealing test device, which greatly reduces the volume of the test cavity, shortens the test time, improves the test efficiency, and reduces the test cost by placing only the end of the camera containing the weld into the cylinder; the interior of the camera is connected to the outside air through a wiring harness. Even if the test time is long and high-pressure gas leaks into the camera through the weld, the high-pressure gas will continue to leak because the interior of the camera is connected to the outside air, and the air pressure in the cylinder cannot maintain the air pressure of the high-pressure gas. Therefore, it is possible to accurately test whether the air tightness of the camera is good, thereby improving the accuracy of the test. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0018] Combination Figures 1 to 3 The utility model is a camera sealing test device, comprising a lens 1, characterized in that: a shell 2 is fixedly connected to the top of the lens 1, an end cover 3 is fixedly connected to the top of the shell 2 through a weld 5, a wiring harness 4 is passed through and fixedly connected to the top of the end cover 3, the lens 1 is arranged in a cylinder 7, a test gas path 8 is passed through the right side of the cylinder 7, a base 6 is fixedly connected to the bottom of the cylinder 7, a base 9 is fixedly connected to the left end of the top of the base 6, a motor 10 is fixedly connected to the top of the base 9, a moving column 11 is fixedly connected to the output shaft of the motor 10, and a fixed grabbing component is arranged at the bottom of the moving column 11.

[0019] By placing only one end of the camera containing the weld 5 into the cylinder 7, the volume of the test cavity is greatly reduced, the test time is shortened, the test efficiency is improved, and the test cost is reduced; the interior of the camera is connected to the outside air through the wiring harness 4. Even if the test time is long, high-pressure gas leaks into the camera through the weld 5. However, since the inside of the camera is connected to the outside air, the high-pressure gas will continue to leak, and the air pressure in the cylinder 7 cannot maintain the air pressure of the high-pressure gas. Therefore, it is possible to accurately test whether the air tightness of the camera is good, thereby improving the accuracy of the test.

[0020] Combination Figure 2 and Figure 3The fixed grabbing assembly includes an electric push rod 12, the bottom of the output end of the electric push rod 12 is fixedly connected to an upper frame 13, the outer side of the upper frame 13 is fixedly connected to three upper hinges 14, the inner side of the upper hinge 14 passes through and is rotatably connected to a support rod 15, the outer side of the support rod 15 passes through and is fixedly connected to a connecting rod 16, the middle of the upper frame 13 passes through and is slidably connected to three guide rods 17, the bottom of the guide rod 17 is fixedly connected to a connecting plate 18, the outer side of the connecting plate 18 is fixedly connected to three lower hinges 19, and the lower hinges 19 are connected through the support rods. The rod 15 is rotatably connected to a claw 20, and a slide groove 21 is provided on the outside of the claw 20. The bottom of the connecting rod 16 is slidably connected to the inside of the slide groove 21. The bottom of the connecting rod 16 can slide along the length direction of the slide groove 21, and the bottom of the connecting rod 16 slides toward one end of the slide groove 21. A caliper 22 is fixedly connected to the bottom of the claw 20, and a silicone protective cover 23 is fixedly connected to the outside of the caliper 22. The angle between the three upper hinges 14 is 120 degrees, and the upper hinge 14 corresponds to the lower hinge 19 in the vertical direction.

[0021] The camera can be grasped and fixed by the electric push rod 12, the upper frame 13, the upper hinge 14, the connecting rod 16, the lower hinge 19, the claw 20 and the caliper 22, and the position can be changed by the motor 10 and the moving column 11, which not only reduces the manual labor but also fixes the camera and improves the accuracy of detection.

[0022] Working principle: During operation, the user starts the motor 10 to rotate the movable column 11. After reaching the fixed position, the electric push rod 12 is started to push the upper frame 13 down along the guide rod 17. As the distance between the upper frame 13 and the connecting plate 18 continues to decrease, the upper end of the connecting rod 16 rotates and drives the lower end to slide inside the slide groove 21, thereby pushing the claw 20 to contract until the caliper 21 catches the camera and stops. The movable column 11 is then rotated to above the detection position. The electric push rod 12 retracts the camera to place the camera in the cylinder 7. The cylinder 7 is pressurized through the test air circuit 8. The air pressure inside the cylinder 7 and the swing of the harness 4 can be observed to detect whether the sealing of the camera is good. It is simple and efficient.
