Description

Technical Field

[0001] The invention relates to the technical field of lens testing, and in particular to a multifunctional optical lens testing device. Background Art

[0002] Optical lenses are essential components in machine vision systems, which directly affect the quality of imaging and the implementation and effect of algorithms. Optical lenses can be divided into short-focus lenses, medium-focus lenses, and long-focus lenses based on focal length; wide-angle, standard, and telephoto lenses based on field of view; and fixed-aperture fixed-focus lenses, manual-aperture fixed-focus lenses, automatic-aperture fixed-focus lenses, manual-zoom lenses, automatic-zoom lenses, automatic-aperture electric-zoom lenses, and electric three-variable (aperture, focal length, and focus are all variable) lenses based on structure.

[0003] In the process of optical lens production and development, it is usually necessary to conduct a series of tests on the stability of the lens, such as air tightness, vibration, waterproofness and bump detection. The lens is subjected to tests in various environments, and finally it is determined whether the lens has a series of damages. Because in actual use, it is necessary to consider various unexpected situations that may occur when the user uses it. The detection of lenses in the prior art is very simple. Generally, vibration detection is performed on vibration detection equipment, and then air tightness detection is performed on air tightness detection equipment. This type of detection, first of all, involves too many detection equipment, and at the same time, it is impossible to detect the performance of the lens, because the single detection environment cannot simulate the complex environment in which the lens is used.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 8A multifunctional optical lens testing device comprises a connecting frame 1; a casing 8; a lens body 7; a positioning assembly 5 for fixing the position of the lens body 7 during detection; a detection assembly 6 for performing multi-directional detection on the lens body 7; the detection assembly 6 comprises air pressure detection, impact detection and vibration detection; a driving assembly 3, the driving assembly 3 is used to provide power for the detection assembly 6 to operate, and simultaneously drive the synchronous operation of air pressure detection, impact detection and vibration detection, the positioning assembly 5 is arranged on the casing 8, and the lens body 7 is located inside the casing 8.

[0032] In this embodiment, the positioning assembly 5 includes two pull rods 51, which are slidably connected to the casing 8. A first spring 52 is sleeved on the surface of the pull rod 51, one end of the first spring 52 is connected to the end surface of the pull rod 51, and the other end of the first spring 52 is connected to the casing 8. The bottom of the pull rod 51 is rotatably connected to a support rod 53, and the bottom of the support rod 53 is connected to a collar 54. A slot is provided on the collar 54, and the bottom of the lens body 7 abuts against the slot. The support rod 53 is rotated to rotate the collar 54 to the rear of the lens body 7, and the rear of the lens body 7 is clamped by the slot on the collar 54. At this time, the upward elastic force provided by the first spring 52 will be used to pull the support rod 53 and the collar 54 through the pull rod 51 to be squeezed and fixed inside the casing 8, thereby realizing the limited fixing of the lens body 7 and clamping it inside the casing 8.

[0033] Furthermore, the driving assembly 3 includes a driving motor 31, which is mounted on the connecting frame 1. The output end of the driving motor 31 is connected to a driving rod 37, to which a wobble plate 32 is fixedly connected, and at both ends of the wobble plate 32, a pendulum wheel 33 is rotatably connected. The impact detection includes a connecting bracket 36, the top of the connecting bracket 36 is rotatably connected to the connecting frame 1, the bottom of the connecting bracket 36 is fixedly connected to the casing 8, the side of the connecting bracket 36 is fixedly connected to a contact plate 34, the wobble plate 32 is located inside the connecting bracket 36, the bottom of the connecting frame 1 is connected to the chassis 2, and the connecting frame 1 is fixedly connected to a striker 39. An arc groove 35 is provided on the connecting bracket 36, and a rubber sleeve 38 is provided at a position on the casing 8 that abuts against the striker 39. The driving motor 31 drives the driving rod 37 to rotate, and the driving rod 37 drives the swing plate 32 to rotate. Each time the pendulum wheel 33 at one end of the swing plate 32 rotates, it will come into contact with the contact plate 34, and then use the abutment method to drive the connecting bracket 36 connected to the contact plate 34 to rotate, and the whole connects The bracket 1 swings in a circular position of the round tube at the top. After swinging to the highest point, when the pendulum wheel 33 of the swing plate 32 is separated from the contact plate 34, the entire connecting bracket 36 is affected by the gravity of the casing 8 and the internal structure, and the gravitational potential energy will be released. At this time, the rubber sleeve 38 connected to the outside of the casing 8 will directly hit the impact rod 39. At this time, the lens body 7 located inside the casing 8 will be subjected to the impact force transmitted to its own interior, thereby simulating the process of lens collision and bumping to achieve an impact test.

[0034] In addition, the air pressure detection includes an abutment plate 601, and two push rods 602 are connected to the bottom of the abutment plate 601. The push rods 602 are slidably connected to the casing 8. The bottom of the push rod 602 is connected to a piston sleeve 603. The surface of the piston sleeve 603 is slidably connected to the inner wall of the casing 8. The surface of the push rod 602 is sleeved with a second spring 604. A one-way valve 608 is provided on the piston sleeve 603. Through the one-way valve 608, gas can be input from the position of the air inlet 609 when the piston sleeve 603 moves back. Because the one-way valve 608 has a one-way conduction, the one-way valve 608 is closed when the gas is squeezed. When air intake is needed, the one-way valve 608 will be opened during the reset sliding, and a certain amount of gas will be taken in to the interior of the casing 8. The casing 8 is provided with an air inlet 609, and the casing 8 is provided with an air outlet device. The air outlet device includes an air outlet pipe 610, and a blocking column 611 is slidably connected inside the air outlet pipe 610. A marking rod 613 is connected to the left side of the blocking column 611, and a scale needle 614 is connected to the marking rod 613. A third spring 615 is connected to the left side of the blocking column 611. The third spring 615 is located inside the air outlet pipe 610. A plurality of air outlet holes 612 are opened on the air outlet pipe 610, and the air outlet pipe 610 is connected to the casing 8. While the swing plate 32 is rotating, it will also drive the abutment plate 601 to slide downward by abutment, thereby using the two push rods 602 to drive the piston sleeve 603 to slide inside the shell 8, driving the internal air to be squeezed. At this time, the air inside the lens body 7 and the shell 8 will be squeezed and will act on the lens installed on the lens body 7. If the lens body 7 is leaking, the air flow will penetrate into the interior of the lens body 7 and be discharged from the tail. If the interior of the lens body 7 is in a sealed state at this time, the air pressure will enter from the position of the air outlet pipe 610, thereby pushing the blocking column 611 to squeeze and slide inside the air outlet pipe 610. When the blocking column 611 moves to the left extreme position, the air outlet 612 will be exposed, so the air flow will be discharged from the position of the air outlet 612.

[0035] In addition, the vibration detection includes a linkage rod 605, the bottom of which is connected to an inner ring 607, the surface of which is rotatably connected to an outer ring 606, and the bottom of the outer ring 606 abuts against the top end surface of the lens body 7. When the piston sleeve 603 slides downward, the inner ring 607 is also driven forward by the four linkage rods 605, thereby driving the outer ring 606 to move slightly, and at this time, the lens body 7 located below the abutment will be forced to move downward, and then through the extrusion force, the support rod 53 and the pull rod 51 are pulled down synchronously to compress the first spring 52. When the swing plate 32 rotates out of the abutment position, it is reset by the elastic force of the first spring 52 and the second spring 604, and the lens body 7 is instantly driven to move upward and reset again, thereby simulating the up and down vibration test of the lens body 7 as a whole.

[0036] It is worth noting that a spiral groove 11 is provided inside the casing 8, and a sliding pin 616 is slidably connected inside the spiral groove 11. The sliding pin 616 is fixed on the outer ring 606. A glue stick 617 is connected to the bottom of the outer ring 606, and the surface of the glue stick 617 abuts against the focus ring on the lens body 7. When the outer ring 606 moves downward, it will also drive the sliding pin 616 to slide in the spiral groove 11, thereby driving the rotation of the outer ring 606. The rotation of the outer ring 606 will drive the glue stick 617 connected thereto to rotate, and the characteristics of the rubber material will be used to abut against the focus ring on the lens body 7, thereby driving it to rotate, thereby simulating the process of user's hand focusing. With the continuous reciprocating action, the position of the focus ring is subjected to fatigue rotation detection, thereby detecting whether there is a focus error problem in the focus ring after long-term use of the lens.

[0037] It is worth noting that the casing 8 is connected with a pipe 9, the end face of the pipe 9 is threadedly connected with a sealing cover, the interior of the casing 8 is provided with a heating pipe 10, and the connecting frame 1 is provided with a timer 4. The user can open the sealing cover, inject a portion of water from the position of the pipe 9, and make it drip on the lens of the lens body 7. If it is in a sealed state, the water will always be on the lens. If there is a gap, the water will flow into the interior of the lens body 7, which means that the sealing structure of the lens needs to be redesigned. The heating pipe 10 is provided to provide a certain high temperature environment, so that the lens body 7 is in a high temperature environment. During the test process, the various connectors of the lens body 7 may have a softening effect under the high temperature state, and the softening will lead to a decrease in the overall structural strength of the structure and a decrease in air tightness. Therefore, by using the generation of high temperature, a simulated detection of the high temperature environment can also be achieved. The entire test time can be intuitively seen through the timer 4 provided. Of course, the timer 4 can also be electrically connected to the drive motor 31 to perform movement timing on the drive motor 31, so that the operator can control the movement timing of the drive motor 31 to time the test process.

[0038] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device for controlling a computer or the like.

[0039] The working principle is that the operator first inserts the lens body 7 to be tested from the position of the chassis 2 into the interior of the casing 8, and then rotates the support rod 53 to rotate the ring 54 to the rear end of the lens body 7, and uses the slot on the ring 54 to lock the rear end of the lens body 7. At this time, the upward elastic force provided by the first spring 52 will pull the support rod 53 and the ring 54 through the pull rod 51 to squeeze and fix them inside the casing 8. At this time, the rotation of the driving motor 31 is controlled, and the driving motor 31 will drive the rotation of the driving rod 37, and the driving rod 37 will drive the rotation of the swing plate 32. The pendulum wheel 33 at one end of the swing plate 32 will come into contact with the contact plate 34 every time it rotates, and then use the abutment method to drive the connecting bracket 36 connected to the contact plate 34 to rotate, and the whole body swings in the circular position of the round tube at the top of the connecting frame 1. After swinging to the highest point, when the pendulum wheel 33 of the swing plate 32 is separated from the contact plate 34, the entire connecting bracket 36 is affected by the gravity of the casing 8 and the internal structure, and the gravitational potential energy is released to achieve the gravity rotation reset of the swing. At this time, the rubber sleeve 38 connected to the outside of the casing 8 will directly hit the impact rod 39. At this time, the lens body 7 located inside the casing 8 will be subjected to the impact force transmitted to its own interior, thereby simulating the process of lens collision and bumping to achieve impact test. While the swing plate 32 is rotating, it will also drive the abutment plate 601 to slide downward by abutment, thereby using the two push rods 602 to drive the piston sleeve 603 to slide inside the sleeve shell 8. The sliding of the piston sleeve 603 will drive the internal air to be squeezed. At this time, the air inside the lens body 7 and the sleeve shell 8 will be squeezed and will act on the lens installed on the lens body 7. If the lens body 7 is leaking, the air flow will penetrate into the interior of the lens body 7 and be discharged from the tail. If the interior of the lens body 7 is in a sealed state at this time, the air pressure will enter from the position of the air outlet pipe 610, thereby pushing the blocking column 611 to squeeze and slide inside the air outlet pipe 610. When the blocking column 611 moves to the left extreme position, the air outlet 612 will be exposed, so the air flow will be discharged from the position of the air outlet 612. When the piston sleeve 603 slides downward, the inner ring 607 is also driven to move forward through the four linkage rods 605, and then the outer ring 606 is driven to move slightly. At this time, the lens body 7 located at the bottom will be forced to move downward, and then through the extrusion force, the support rod 53 and the pull rod 51 are pulled down synchronously to compress the first spring 52. When the pendulum plate 32 rotates out of the abutment position, it is reset by the elastic force of the first spring 52 and the second spring 604, and the lens body 7 is instantly driven to move upward and reset again, thereby simulating the up and down vibration test of the lens body 7 as a whole. The impact test is lateral during the impact test, and the vibration test is in the up and down axial direction, so the overall axial and radial two-way detection is realized, so as to realize whether the installation position or design structure of the lens inside the lens body 7 can withstand the multi-directional test.When the outer ring 606 moves downward, it will also drive the sliding pin 616 to slide in the spiral groove 11, thereby driving the outer ring 606 to rotate. The rotation of the outer ring 606 will drive the rubber stick 617 connected thereto to rotate, and utilize the characteristics of the rubber material to abut against the focus ring on the lens body 7, thereby driving it to rotate, thereby simulating the process of user hand focusing. With continuous reciprocating movements, the position of the focus ring is subjected to fatigue rotation detection, thereby detecting whether there is a focusing error problem with the focus ring under long-term use of the lens. Therefore, the lens body 7 is subjected to multiple detections of collision-vibration-air pressure-fatigue as a whole, and the whole process is not a single operation. For example, after a collision or vibration, the air pressure detection will be cyclically carried out, and at this time, it will be detected whether there is a hidden danger in the sealing of the lens body 7 after the collision. Compared with a single detection, this multiple reciprocating cyclic overlap detection can simulate a more complex working environment and test the actual stability of the lens body 7.

[0040] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
