Abstract
Description
Technical Field
[0001] This utility model relates to the field of adjustment equipment, and in particular to a separate high-precision six-degree-of-freedom adjustment component. Background Technology
[0002] As the requirements for camera clarity become increasingly stringent, active focusing is becoming more widespread. Based on the camera's structure, active focusing can be divided into two types: lens focusing and chip focusing. To achieve production compatibility, existing equipment typically uses a six-DOF micro-adjustment robot to adjust the chip, and another six-DOF micro-adjustment robot to adjust the lens. This method is expensive, structurally complex, and has low production efficiency, representing a pain point that the industry urgently needs to address.
[0003] Active alignment technology has been around for many years and has gradually become a standard feature in the automotive camera industry. With the development of new energy technologies, the variety of automotive camera products is increasing, product structures are becoming more customized, and product cost control is becoming more stringent. The original active alignment technology is increasingly failing to meet customer needs in terms of cost, efficiency, ease of use, and maintainability.
[0004] Existing technologies currently suffer from drawbacks such as complex structures, inability to achieve rapid alignment of large-volume products, difficult maintenance, high costs, complex logic, and low efficiency. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a separate, high-precision, six-degree-of-freedom adjustment component.
[0006] To address the problems existing in the prior art, the present invention adopts the following technical solution:
[0007] A separate high-precision six-degree-of-freedom adjustment assembly includes a frame base, an adjustment assembly, a first fixing component, and a second fixing component;
[0008] The adjustment component is slidably mounted on the frame base, and the frame base is provided with a drive component for driving the adjustment component to slide.
[0009] The first fastener is mounted on the adjustment assembly and is used to fix the product in use.
[0010] The second fixing member is mounted on the adjustment assembly and is used to clamp and fix the lens in use.
[0011] Furthermore, the driving component includes a moving module, a module slider, and a fixed plate; the fixed plate is mounted on the frame base; the moving module is mounted on the frame base and connected to the fixed plate; the module slider is slidably mounted on the moving module, and the fixed plate is provided with a drive motor for driving the module slider to slide.
[0012] Furthermore, the adjustment assembly includes a first separate fine-tuning manipulator and a second separate fine-tuning manipulator; the first separate fine-tuning manipulator is vertically slidably mounted on the module slider; the second separate fine-tuning manipulator is mounted on the fixed plate.
[0013] Furthermore, a hydraulic cylinder is provided on the module slider, and the first separate fine-tuning manipulator is connected to the telescopic end of the hydraulic cylinder.
[0014] Furthermore, the first fixing member is a positioning clamp, which is mounted on the first detachable fine-tuning manipulator.
[0015] Furthermore, the second fixing member is a clamping claw, which is mounted on the second split-type micro-adjustment manipulator and holds a camera.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] In this invention, by setting an adjustment component, the fine-tuning manipulator becomes the core component of the equipment. By reducing the degrees of freedom of the fine-tuning manipulator by half, along with other components, the total cost of the equipment is significantly reduced. After the mechanism is simplified, more space can be provided for the product to be tested, and the compatible product volume is increased. Maintenance is simple, and the total number of electrical and mechanical parts of the equipment is also greatly reduced. The original redundant logic is simplified, the movement is simple, and the efficiency is increased. The accuracy is improved. The original equipment's lens alignment accuracy was lower than the chip alignment accuracy. After the application of this equipment, the product accuracy is greatly improved.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Example: This example provides a separate high-precision six-degree-of-freedom adjustment component, see [link / reference]. Figures 1-4 Specifically, it includes a frame base 1, an adjustment component, a first fixing component, and a second fixing component; the adjustment component is slidably mounted on the frame base 1, and the frame base 1 is provided with a driving component for driving the adjustment component to slide; the first fixing component is mounted on the adjustment component and is used to fix the product in use; the second fixing component is mounted on the adjustment component and is used to clamp and fix the lens in use.
[0026] In the specific implementation process, such as Figure 1 As shown, the driving component includes a movable module 2, a module slider 3, and a fixed plate 9; the fixed plate 9 is mounted on the frame base 1; the movable module 2 is mounted on the frame base 1 and connected to the fixed plate 9; the module slider 3 is slidably mounted on the movable module 2, and the fixed plate 9 is provided with a drive motor 11 for driving the module slider 3 to slide.
[0027] In the specific implementation process, such as Figure 1 As shown, the adjustment assembly includes a first separate fine-tuning manipulator 5 and a second separate fine-tuning manipulator 7. The first separate fine-tuning manipulator 5 is vertically slidably mounted on the module slider 3, and a hydraulic cylinder 4 is mounted on the module slider 3. The first separate fine-tuning manipulator 5 is connected to the telescopic end of the hydraulic cylinder 4. The second separate fine-tuning manipulator 7 is mounted on the fixed plate 9. The first separate fine-tuning manipulator 5 and the second separate fine-tuning manipulator 7 have a total of 6 different degrees of freedom. As is well known, an object has only six degrees of freedom relative to another object. Therefore, two separate fine-tuning manipulators can complete all relative movements between the chip and the lens. Compared with the redundant movement of the traditional 12 degrees of freedom, the separate design has a clearer and simpler motion logic, reduces moving parts, and has higher precision.
[0028] In the specific implementation process, such as Figure 2 and Figure 3As shown, the first fixing member is a positioning clamp 6, which is mounted on the first split-type micro-adjustment robot 5 and is used to fix the chip; the second fixing member is a gripping claw 8, which is mounted on the second split-type micro-adjustment robot 7 and holds the camera 10.
[0029] Specifically, the working principle and operation method of this utility model are as follows:
[0030] In use, the drive motor 11 is turned on by controlling an external switch, thereby driving the module slider 3 to slide on the moving module 2. This transports the hydraulic cylinder 4, the first separate fine-tuning robot 5, the positioning fixture 6, and the product on the positioning fixture 6 together to the area below the second separate fine-tuning robot 7. The gripper 8 on the second separate fine-tuning robot 7 holds the camera 10 above the product, and then the active alignment operation begins. In the original equipment, active alignment was divided into lens alignment and chip alignment according to the product structure, adjusting their respective six degrees of freedom, while neglecting the other component. This resulted in wasted degrees of freedom and low precision. Therefore, the combined use of the first separate fine-tuning robot 5 and the second separate fine-tuning robot 7 can fully utilize all degrees of freedom to achieve linkage adjustment of the chip and the lens. It is not necessary to distinguish between product structures, lenses, or chips. The first separate fine-tuning robot 5 and the second separate fine-tuning robot 7 can be used uniformly to align the lens and the chip simultaneously, resulting in higher precision and stronger compatibility.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
