Description

Technical Field

[0001] This utility model relates to the field of infrared equipment optical axis adjustment technology, and in particular to a visual tooling suitable for optical axis autocollimation. Background Technology

[0002] During the optical axis calibration of infrared products, with the increasing market demand for complete infrared devices and users' increasingly higher requirements for product image quality, strict process control is essential. Optical axis calibration is a prerequisite for ensuring the consistency of the image focal plane, and optical self-calibration is an inherent process for establishing calibration benchmarks. This process requires the cooperation of three people: one person is responsible for attaching the mirror surface, one person operates the turntable rotation, and one person observes the position of the crosshairs.

[0003] Having three people work together on a single task results in wasted manpower. The person operating the turntable cannot see the collimator during autocollimation and needs to repeatedly adjust their position according to the observer's instructions, making the debugging process cumbersome. In addition, because different people observe the crosshairs at different times, the entire autocollimation process is relatively time-consuming and inefficient. Utility Model Content

[0004] This invention provides a visual fixture suitable for optical axis autocollimation, which solves the problems of cumbersome and inefficient optical axis debugging operations for infrared products.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A suitable optical axis autocollimation visualization fixture is provided, comprising:

[0007] Turntable;

[0008] Collimator, including a light source with adjustable brightness;

[0009] A reference bracket is detachably connected to the work turntable; the reference bracket is configured as a partially hollowed-out L-shaped plate structure for placing the infrared unit; one side of the reference bracket is configured as a reference surface for the debugging process;

[0010] A reflector fixing fixture is detachably connected to the reference bracket. The reflector fixing fixture includes an L-shaped first fixing member, one end of which is connected and fixed to the reference bracket, and the other end of which forms a structure protruding from the reference surface. A rectangular adapter plate is detachably connected to the protruding end of the first fixing member. A mirror holder for placing the reflector is detachably connected to the adapter plate. The mirror holder has a semi-enclosed frame structure and an open groove for placing a reflector protective ring, forming a structure in which the reflector is pressed and fixed to the open groove by the reflector protective ring.

[0011] The video equipment includes a camera, a camera bracket, and a display; the camera is aligned with the observation port of the collimator via the camera bracket, forming a structure that displays a crosshair light and shadow image within the observation port on the display.

[0012] Furthermore, the mirror fixing fixture also includes an L-shaped second fixing member, one end of which is detachably connected to the top of the reference bracket, and the other end protrudes from the reference surface and forms a structure that limits the mirror position with the mirror holder.

[0013] Furthermore, the end of the second fixing member near the reference bracket is in the shape of a concave rod, forming a structure within the concave area that accommodates the reflector protective ring and the reflector.

[0014] Furthermore, an adjustable bolt is provided at the end of the second fixing member away from the reference bracket. The adjustable bolt is threadedly connected to the corresponding threaded hole of the second fixing member, and the end of the adjustable bolt near the reflector abuts against the reflector.

[0015] Furthermore, the detachable connection is configured to be a screw thread connection.

[0027] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the technical solutions in the embodiments of this application are clearly described. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art are within the scope of protection of this application.

[0028] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0029] The steps described in the specification and the flowcharts in the accompanying drawings of this utility model are not necessarily to be strictly followed according to the step numbers; the execution order of the steps can be changed. Furthermore, certain steps can be omitted, multiple steps can be combined into one step, and / or one step can be broken down into multiple steps.

[0030] The following detailed description, in conjunction with the accompanying drawings and preferred embodiments, describes the optical axis autocollimation visualization fixture provided in this application.

[0031] For the special step of optical axis calibration, the operation process is critical. If the optical axis is not calibrated accurately, all subsequent work indicators will fail to meet the requirements.

[0032] See Figure 1 The main steps of the traditional debugging method are as follows:

[0033] a) Install the infrared unit onto the turntable and have one person rotate it left and right, while another person sets up the reflector and moves the reflector.

[0034] b) Position the crosshair target correctly and place it into the observation port of the collimator.

[0035] c) Place the observation frame into the observation port and turn on the light source.

[0036] d) Observe the reflected light and shadow of the crosshairs inside the collimator through the observation port. The white crosshairs are the image of the target itself, and the black crosshairs are the reflected light from the mirror.

[0037] e) The observer at the reticle guides the operator at the console to adjust the position of the infrared unit (this step is the most time-consuming in the entire autocollimation process).

[0038] Using the above method, the operator of the turntable cannot see the situation inside the collimator during the autoalignment process and needs to repeatedly adjust the position according to the observer's instructions, making the debugging process cumbersome. Based on this, this application provides a visual fixture suitable for optical axis autoalignment. This fixture can achieve rapid autoalignment by a single person, improve production speed and efficiency, reduce wasted motion, and facilitate production operations.

[0039] See Figure 2 This application provides a visualization fixture suitable for optical axis autocollimation, comprising:

[0040] Turntable;

[0041] Collimator, including a light source with adjustable brightness;

[0042] The reference bracket 1 is detachably connected to the work turntable; the reference bracket 1 is configured as a partially hollowed-out L-shaped plate structure for placing the infrared unit; one side of the reference bracket 1 is configured as a reference surface for the debugging process.

[0043] The reflector fixing fixture 2 is detachably connected to the reference bracket 1; see also Figure 2-6 The reflector fixing fixture 2 includes an L-shaped first fixing member 201. One end of the first fixing member 201 is connected and fixed to the reference bracket 1, and the other end forms a structure that protrudes from the reference surface. A rectangular adapter plate 202 is detachably connected to the protruding end of the first fixing member 201. The adapter plate 202 is detachably connected to a mirror holder 203 for placing the reflector 3. The mirror holder 203 has a semi-enclosed frame structure. The mirror holder 203 is provided with an open groove 2031 for placing the reflector protective pressure ring 204, forming a structure in which the reflector 3 is pressed and fixed to the open groove 2031 by the reflector protective pressure ring 204.

[0044] The video equipment includes a camera, a camera bracket, and a display; the camera is aligned with the observation port of the collimator via the camera bracket, forming a structure that displays a crosshair light and shadow image within the observation port on the display.

[0045] In some possible implementations, the mirror fixing fixture 2 further includes an L-shaped second fixing member 205, one end of which is detachably connected to the top of the reference bracket 1, and the other end protrudes from the reference surface and forms a structure with the mirror holder 203 to limit the position of the mirror 3.

[0046] In some possible implementations, the second fastener 205 is in the shape of a concave rod at one end near the reference bracket 1, forming a structure that accommodates the reflector protective ring 204 and the reflector 3 within the concave area.

[0047] In some possible implementations, the second fixing member 205 is provided with an adjustable bolt at the end away from the reference bracket 1. The adjustable bolt is threadedly connected to the corresponding threaded hole of the second fixing member, and the end of the adjustable bolt near the reflector 3 abuts against the reflector 3.

[0048] In practice, the aforementioned detachable connection can be configured to be connected via screw threads.

[0049] See Figure 7 In this embodiment of the application, one person can operate the workbench to complete the automated work. Specifically, the operation steps are as follows:

[0050] Step 1. Aim the camera at the observation port of the microscope tube.

[0051] Step 2. Connect the monitor and camera to power, and turn on the power supply for the collimator's light source.

[0052] Step 3. Adjust the camera's focus and ISO, and adjust the power supply voltage of the light source until the image on the monitor is clear. (A 2K high-definition zoom camera replaces visual observation, transmitting the image to the monitor, eliminating the need for personnel to observe the crosshairs. When the camera observes the crosshairs within the collimator, the intensity of the light source directly affects the clarity; therefore, it is necessary to adjust the light source brightness.)

[0053] Step 4. Observe the monitor and operate the turntable according to the image.

[0054] The optical axis auto-alignment adjustment method is as follows:

[0055] The crosshair (white) and the crosshair reflection (black) are clearly visible on the monitor. The knobs on the fine-tuning turntable align and overlap the black and white crosshairs, allowing one person to complete the entire optical axis auto-alignment process.

[0056] This application embodiment utilizes the principle of visual tooling to significantly reduce the number of operators, effectively lowering labor costs from three to one. After multiple on-site optical autoalignment tests conducted by department experts and process engineers, comparing the tooling with the original debugging method, this tooling meets the requirements for production autoalignment. Its advantages include saving manpower and time, replacing manual operation, strong stability, solidifying autoalignment process standards, and gradually achieving standardization of autoalignment processes. The department's current production tasks (T20 production) have adopted this tooling for debugging, and its stability, accuracy, and convenience have proven highly effective. Statistics show that the operation time per machine has been reduced from 20 minutes to 8 minutes, and the production cycle time per machine has been shortened by 12 minutes. If the original method produced 22 units per day, the improved method can produce 56 units per day, greatly improving production efficiency.
