Description

Technical Field

[0001] The utility model relates to the technical field of dual-filter inspection, and more particularly to a test bench for inspecting a dual-filter switcher. Background Art

[0002] Filters are made of plastic or glass with a special dye added. A red filter only allows red light to pass through, and so on. The transmittance of glass is originally similar to that of air, allowing all colored light to pass through, making it transparent. However, after being dyed, the molecular structure changes, and the refractive index also changes, which changes the ability of certain colors of light to pass through. For example, a beam of white light passing through a blue filter will emit a blue beam, while green and red light will be very small, as most of the light is absorbed by the filter.

[0003] Some cameras are equipped with dual filters, which are switched by a switch to improve photography efficiency and photo quality. The dual filter switch needs to be inspected after production to ensure product quality. The most common inspection method is to fix the switch on the test bench, illuminate the switch surface with concentrated light of the same specification, and determine the product quality by recording the purity of different decomposed light.

[0004] However, most of the test benches in the existing technology can only fix single-specification switches. If filters of other sizes need to be inspected, the staff needs to disassemble the filter clamps to adapt to the size of the filter for positioning. The subsequent position adjustment process is not only cumbersome but also affects the efficiency of the inspection. For this reason, this solution proposes a test bench for inspecting dual-filter switches. Utility Model Content

[0031] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," "provided with," "provided on," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components.

[0032] See also Figure 1-5 A test bench for inspecting a dual-filter switcher comprises a bracket 1, a base 2 being fixedly connected to one side of the bottom end of the bracket 1, a light transmitting mirror 3 being installed at the central end of the base 2, a top plate 4 being fixedly connected to one side of the top end of the bracket 1, a microscope 5 being installed at the bottom end of the top plate 4, a Y-axis adjustment component being installed on the central side wall of the bracket 1, the upper end of the Y-axis adjustment component being movably connected to a bearing platform 6, a slide groove 61 being provided at the upper end of one side of the bearing platform 6, an X-axis adjustment component 7 being movably installed between the inner walls of the slide groove 61, and a positioning component 8 being provided at the upper end of one side of the X-axis adjustment component 7.

[0033] During use of this solution, the operator first moves the positioning component 8 on one side, then places the dual-filter switcher to be inspected on the surface of the carrier 6 and clamps it with the action of the positioning component 8. Then, the operator adjusts the position of the Y-axis adjustment component and the X-axis adjustment component 7 according to the size of the dual-filter switcher, enabling a full range of inspection of the dual-filter switcher for subsequent testing work;

[0034] Compared with the prior art, the present invention can position and clamp dual-filter switches of different sizes to facilitate subsequent stable inspection work. At the same time, under the action of the Y-axis adjustment component and the X-axis adjustment component 7, the position of the clamped and positioned dual-filter switch can be fine-tuned, thereby enabling a comprehensive inspection of the dual-filter switch, observing the surface morphology and internal structure of the filter, and checking whether the filter has contamination, defects, and damage problems, thereby saving a lot of time during the test process, greatly improving the inspection efficiency, and having a wide range of applications.

[0035] See also Figure 1-2 The Y-axis adjustment assembly includes a carrier box 91 fixedly connected to the central side wall of the bracket 1, and a threaded rod 92 is rotatably connected between the inner walls of the carrier box 91. One end of the threaded rod 92 passes through the outside of the bracket 1 and is fixedly connected to a handle 94. A sliding sleeve 93 is provided between the inner walls of the carrier box 91, and the top end of the sliding sleeve 93 is fixedly connected to the carrier platform 6. The sliding sleeve 93 is sleeved on the outside of the threaded rod 92 and is threadedly connected to it.

[0036] During use of this solution, when a person needs to adjust the front and rear position of the dual filter switch, the person can rotate the handle 94 to cause the threaded rod 92 to rotate. At the same time, under the action of the threaded transmission, the sleeve 93 converts the rotational motion of the threaded rod 92 into linear motion, thereby realizing the front and rear linear motion inside the carrier box 91. As a result, the front and rear movement of the sleeve 93 can drive the carrier platform 6 to move synchronously, thereby realizing position adjustment in the front and rear directions.

[0037] See also Figure 1 and Figure 3-4 The X-axis adjustment component 7 includes an adjustment plate 71 provided between the inner walls of the slide groove 61, a groove 72 is provided at the bottom end of one side of the adjustment plate 71, and a plurality of evenly distributed one-way teeth 73 are fixedly connected to the inner wall of the groove 72.

[0038] More specifically: a built-in groove 611 is provided on the side wall of the slide groove 61, a through hole 612 is provided at the upper end of the slide groove 61, the through hole 612 and the built-in groove 611 are connected to each other, the inner bottom end of the built-in groove 611 is rotatably connected to the limit bar 74, the transmission shaft of the limit bar 74 is located at the lower side of the through hole 612, the upper end of the transmission shaft of the limit bar 74 is fixedly connected with a rotary cap 76, the inner wall of the built-in groove 611 is fixedly connected with a torsion spring piece 75, and one end of the torsion spring piece 75 is in contact with the surface of the limit bar 74.

[0039] When the adjustment plate 71 is in the proper position, the limit bars 74 are pressed against the one-way latching teeth 73 and rotated counterclockwise. When the adjustment plate 71 is in the proper position, the limit bars 74 are no longer under pressure. The torsion springs 75, due to their reset characteristics, drive the limit bars 74 to press against the two slots where the one-way latching teeth 73 are set, preventing the adjustment plate 71 from moving to the right and preventing position deviation.

[0040] When the personnel needs to move the dual filter switch to the right, they first rotate the rotary cap 76, thereby pressing the limit bar 74 against the side of the torsion spring 75, so that one end of the limit bar 74 is no longer engaged between the slots of the two one-way teeth 73. At this time, the adjustment plate 71 can achieve free left and right displacement movement. Then, when the personnel pulls the adjustment plate 71 to the appropriate position on the right side, they release the rotary cap 76, and then, through the reset characteristics of the torsion spring 75, the limit bar 74 is driven to press again between the slots of the two one-way teeth 73, prompting the adjustment plate 71 to be positioned.

[0041] See also Figure 1 and Figure 5 The positioning assembly 8 includes an arc-shaped positioning plate 81 fixedly connected to the upper end of the X-axis adjustment assembly 7, the side end of the arc-shaped positioning plate 81 is fixedly connected to a connecting seat 82, the lower end of the connecting seat 82 is rotatably connected to a positioning rod 83, a torsion spring is installed between the positioning rod 83 and the connecting seat 82, and the side end of the positioning rod 83 is fixedly connected to a handle 84.

[0042] During use of this solution, when it is necessary to clamp and position dual-filter switches of different sizes, the operator can first turn the handle 84 clockwise to cause the positioning rod 83 to rotate, thereby expanding the distance between the arc-shaped positioning plate 81 and the positioning rod 83, and then place the dual-filter switch inside it. The operator then releases the handle 84, causing the positioning rod 83 to rebound and press against one side of the dual-filter switch under the action of the torsion spring, thereby positioning it and limiting it, which is beneficial for subsequent inspection work.

[0043] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
