Description

Technical Field

[0001] This invention relates to the field of lens assembly equipment technology, and more particularly to a lens assembly device for autonomous vehicles. Background Technology

[0002] Cameras are used in many fields, such as computers, automobiles, and multimedia. As the application scope of cameras expands, the requirements for camera manufacturing are becoming increasingly stringent.

[0003] In the existing technology, the camera manufacturing process requires multiple lenses to be installed into the lens barrel one by one. In the actual assembly process, it is necessary to ensure that the central axis of the lens coincides with the central axis of the lens barrel in order to ensure the qualification rate of the assembled lens. However, in the existing equipment assembly process, there is a phenomenon of deviation between the central axis of the lens and the central axis of the lens barrel, which leads to high production costs and affects production quality, and needs to be improved. Summary of the Invention

[0004] In order to overcome the problems of high production cost and uncontrollable production quality of existing cameras, the purpose of this invention is to provide a lens assembly device for autonomous vehicles, which improves the controllability of production quality and reduces production costs.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A lens assembly device for autonomous vehicles includes a frame, a lens barrel feeding assembly, a lens barrel transfer robot, a lens feeding assembly, a lens transfer robot, and an assembly mechanism.

[0007] The assembly mechanism includes a crossbeam, a lens barrel fixing component, a first driving component, a lifting plate, a lens correction component, a second driving component, a push plate, and a guide post. The crossbeam is mounted on the frame, the lens barrel fixing component is mounted on the frame, and the lens barrel fixing component is located between the lens barrel feeding assembly and the lens feeding assembly. The first driving component is mounted on the crossbeam and drives the lifting plate to move towards or away from the lens barrel fixing component. The lens correction component is mounted on the lifting plate and located directly above the lens barrel fixing component. The lifting plate has a through hole. The second driving component is mounted on the crossbeam and drives the push plate to move up and down. The guide post is mounted on the lens barrel fixing component, and the lifting plate is slidably connected to the guide post.

[0008] The lens barrel transfer robot transfers the external lens barrel in the lens barrel feeding assembly to the lens barrel fixing component, the lens transfer robot transfers the external lens in the lens feeding assembly to the lens correction component, and the pusher plate passes through the through hole to push the external lens in the lens correction component into the external lens barrel.

[0009] Furthermore, the lens correction component includes a guide cylinder, which is open at both ends, and the central axis of the guide cylinder, the central axis of the through hole, and the central axis of the lens barrel fixing component coincide.

[0010] Furthermore, the guide cylinder includes a feeding section, a correction section, and a discharging section connected in sequence. The feeding section is located near the through hole and is funnel-shaped. The radial dimensions of the correction section are the same as those of the outer lens, and the radial dimensions of the discharging section are greater than those of the correction section.

[0011] Furthermore, the lens correction component also includes a sealing plate, an inflation component, and a third driving component. The feeding part is provided with a side perforation. The third driving component drives the sealing plate to cover the feeding part of the guide cylinder. The external high-pressure airflow of the inflation component enters the guide cylinder through the side perforation.

[0012] Furthermore, the lens correction component also includes a hollow rod and an inner movable rod. The hollow rod is connected to a sealing plate, and the inner movable rod is connected to a push plate. The third driving component drives the hollow rod to rise and fall, and the second driving component drives the inner movable rod to rise and fall.

[0013] Furthermore, the lens barrel feeding assembly includes a material tray and a rotating drive component. The material tray is provided with several grooves, and the rotating drive component is located on the frame and drives the material tray to rotate so that the grooves are located directly below the lens barrel transfer robot.

[0014] Furthermore, the lens barrel feeding assembly includes a lifting mechanism, which is mounted on the frame and pushes the external lens in the groove toward the lens barrel transfer robot.

[0015] Furthermore, the lens barrel fixing component includes several claws, which surround a receiving cavity for fixing the external lens barrel.

[0016] The beneficial effects of this invention are as follows: The lens barrel transfer robot transfers the outer lens barrel of the lens barrel feeding assembly to the lens barrel fixing component. The first driving component drives the lifting plate to move up and down, causing the lens correction component to move toward the lens barrel fixing component until they collide. The lens transfer robot transfers the outer lens in the lens feeding assembly to the lens correction component. Under the action of the lens correction component, the outer lens is corrected. Then, the second driving component drives the push plate to pass through the through hole and enter the lens correction component to push the corrected lens into the outer lens barrel, completing the assembly of the lens and the lens barrel. This achieves the purpose of automatic correction and automatic assembly, improving production efficiency. Attached Figure Description

[0037] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0038] Please see Figures 1 to 3 The present invention provides a lens assembly device for autonomous vehicles, comprising a frame, a lens barrel feeding assembly 1, a lens barrel transfer robot 2, a lens feeding assembly 3, a lens transfer robot 4, and an assembly mechanism 5.

[0039] The assembly mechanism 5 includes a crossbeam 51, a lens barrel fixing component 52, a first driving component 53, a lifting plate 54, a lens correction component 55, a second driving component 56, a push plate 57, and a guide post 58. The crossbeam 51 is mounted on the frame, and the lens barrel fixing component 52 is mounted on the frame. The lens barrel fixing component 52 is located between the lens barrel feeding assembly 1 and the lens feeding assembly 3. The first driving component 53 is mounted on the crossbeam 51 and drives the lifting plate 54 to move towards or away from the lens barrel fixing component 52. The lens correction component 55 is mounted on the lifting plate 54 and is located directly above the lens barrel fixing component 52. The lifting plate 54 has a through hole 541. The second driving component 56 is mounted on the crossbeam 51 and drives the push plate 57 to move up and down. The guide post 58 is mounted on the lens barrel fixing component 52, and the lifting plate 54 is slidably connected to the guide post 58.

[0040] The lens barrel transfer robot 2 transfers the external lens barrel in the lens barrel feeding assembly 1 to the lens barrel fixing member 52, the lens transfer robot 4 transfers the external lens in the lens feeding assembly 3 to the lens correction member 55, and the push plate 57 pushes the external lens in the lens correction member 55 into the external lens barrel through the through hole 541.

[0041] Specifically, in this embodiment, the assembly mechanism 5 is located between the lens barrel feeding assembly 1 and the lens feeding assembly 3. The length direction of the crossbeam 51 is perpendicular to the length direction of the frame. The first driving member 53 is located on the crossbeam 51 and drives the lifting plate 54 to move up and down. The lens correction member 55 is fixed on the lower surface of the lifting plate 54. The lifting plate 54 has a through hole 541. The second driving member 56 is located on the crossbeam 51 and drives the push plate 57 to move up and down, so that the push plate 57 passes through the through hole 541 and moves back and forth between the top and bottom of the through hole 541. The lens barrel fixing member 52, the lens correction member 55, and the push plate 57 are arranged sequentially from bottom to top, and the central axis of the lens barrel fixing member 52, the central axis of the lens correction member 55, and the central axis of the push plate 57 coincide. The working principle is as follows: First, the first driving member 53 drives the lifting plate 54 to move upward. Simultaneously, the lens correction member 55 moves upward away from the lens barrel fixing member 52, and the lens barrel is transferred. Robotic arm 2 transfers the external lens barrel located in lens barrel feeding assembly 1 to lens barrel fixing member 52. Then, the first driving member 53 drives the lifting plate 54 to move downward, so that the lens correction member 55 abuts against the external lens barrel 100 fixed in lens barrel fixing member 52. Then, the lens transfer robotic arm 4 transfers the external lens located in lens feeding assembly 3 to lens correction member 55. After the lens correction member 55 corrects the lens, the second driving member 56 drives the push plate 57 to move downward. The push plate 57 passes through the through hole 541 and enters the lens correction member 55, presses the lens 200 in the lens correction member 55 and pushes the lens 200 into the lens barrel 100, completing the assembly of the lens 200 and the lens barrel 100. The setting of the guide post 58 ensures the stability of the movement direction of the lifting plate 54, ensures that the central axis of the lens correction member 55 and the central axis of the lens barrel fixing member 52 are always in a coincident state, and ensures the accuracy of the lens and lens barrel assembly.

[0042] The lens barrel transfer robot 2 transfers the outer lens barrel of the lens barrel feeding assembly 1 to the lens barrel fixing part 52. The first drive unit 53 drives the lifting plate 54 to rise and fall, so that the lens correction part 55 moves toward the lens barrel fixing part 52 until they collide. The lens transfer robot 4 transfers the outer lens in the lens feeding assembly 3 to the lens correction part 55. Under the action of the lens correction part 55, the correction of the outer lens is completed. Then, the second drive unit 56 drives the push plate 57 to pass through the through hole 541 and enter the lens correction part 55 to push the corrected lens into the outer lens barrel, completing the assembly of the lens and the lens barrel, realizing the purpose of automatic correction and automatic assembly, and improving production efficiency.

[0043] Please see Figures 4 to 5 The lens correction component 55 includes a guide cylinder 551, which is open at both ends. The central axis of the guide cylinder 551, the central axis of the through hole 541, and the central axis of the lens barrel fixing component 52 are coincident. The guide cylinder 551 ensures that the central axis of the external lens 200 is coincident with the central axis of the external lens barrel 100, thus ensuring the accuracy of assembly.

[0044] The guide cylinder 551 includes a feeding section 5511, a correction section 5512, and a discharging section 5513 connected in sequence. The feeding section 5511 is located near the through hole 541 and is funnel-shaped. The radial dimension of the correction section 5512 is the same as that of the outer lens. The radial dimension of the discharging section 5513 is larger than that of the correction section 5512. The longitudinal section of the feeding section 5511 is inverted trapezoidal, that is, the radial dimension of the opening end of the feeding section 5511 towards the correction section 5512 gradually decreases until it is the same as that of the correction section 5512. This structure makes it easier for the lens transfer robot 4 to put the outer lens into the feeding section 5511. As the radial dimension of the feeding section 5511 gradually decreases, the lens slides down the feeding section 5511 into the correction section 5512, thereby ensuring that the central axis of the lens coincides with the central axis of the lens barrel held by the lens barrel fixing member 52, and ensuring the accuracy of the lens and lens barrel assembly.

[0045] The lens correction component 55 further includes a sealing plate 552, an inflation component 553, and a third driving component 554. The feeding section 5511 is provided with a side perforation 55111. The third driving component 554 drives the sealing plate 552 to cover the feeding section 5511 of the guide cylinder 551. The external high-pressure gas flow from the inflation component 553 enters the guide cylinder 551 through the side perforation 55111. Preferably, the inflation component 553 is used to store external high-pressure gas. When an external lens enters the guide cylinder 551, the third driving component 554 drives... The dynamic sealing plate 552 covers the port of the feeding section 5511. At this time, the sealing plate 552, the feeding section 5511 and the external lens form a sealed space. The high-pressure gas in the inflation component 553 enters the sealed space through the side perforation 55111 to form a high-pressure chamber. Under the action of the high-pressure gas, the initial correction of the horizontal plane of the external lens is completed. Then, the second driving component 56 drives the push plate 57 to press the lens and further perform micro-correction on the lens. Then, the second driving component 56 drives the push plate 57 to move downward until the lens enters the lens barrel.

[0046] Please see Figure 6 The lens correction component 55 also includes a hollow rod 591 and an inner movable rod 592. The hollow rod 591 is connected to the sealing plate 552, and the inner movable rod 592 is connected to the push plate 57. The third driving component 554 drives the hollow rod 591 to rise and fall, and the second driving component 56 drives the inner movable rod 592 to rise and fall. This structure allows the sealing plate 552 and the push plate 57 to rise and fall synchronously, resulting in a compact structure. It also ensures that the coaxiality of the sealing plate 552 and the push plate 57 remains constant, improving assembly accuracy.

[0047] The hollow rod 591 is provided with a guide hole 5911, which is arranged along the axis of the hollow rod 591. The inner movable rod 592 is provided with a protrusion 5921, which passes through the guide hole 5911 and exits the hollow rod 591. The output end of the second driving member 56 is connected to the protrusion 5921, so as to realize the purpose of controlling the independent lifting and lowering of the sealing plate 552 and the push plate 57, and meet the usage requirements of separate control.

[0048] Please see Figure 7 The lens barrel feeding assembly 1 includes a material tray 11 and a rotation drive 12. The material tray 11 is provided with a plurality of grooves 111. The rotation drive 12 is located on the frame and drives the material tray 11 to rotate so that the grooves 111 are located directly below the lens barrel transfer robot 2. The rotation drive 12 drives the material tray 11 to rotate, so that the external lens barrels in the grooves 111 move one by one to directly below the lens barrel transfer robot 2, thus completing the feeding purpose.

[0049] The lens barrel feeding assembly 1 includes a lifting mechanism 13, which is mounted on the frame. The lifting mechanism 13 pushes the external lens in the groove 111 toward the lens barrel transfer robot 2. The lifting mechanism 13 pushes the external lens in the groove 111 upward, which facilitates the precise gripping of the lens barrel transfer robot 2.

[0050] Please see Figure 8 The lens barrel fixing component 52 includes a plurality of claws 521, which form a receiving cavity. The receiving cavity is used to fix the external lens barrel, and the plurality of claws 521 provide initial fixation for the external lens barrel.

[0051] The lens barrel fixing component 52 also includes a connecting rod 522 and several rings 523. The connecting rod 522 is located on the clasp 521 and extends away from the clasp 521. The rings 522 are arranged sequentially from top to bottom, with a spacing between adjacent rings 522. The rings 523 clamp and fix the external lens barrel. The structure of several rings 523 arranged sequentially from bottom to top further fixes the lens barrel, ensuring that the central axis of the fixed lens barrel coincides with the central axis of the lens correction component 55, thus ensuring the accuracy of assembly.

[0052] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
