Description

Technical Field

[0001] This utility model belongs to the field of filter testing technology, specifically relating to an auxiliary tooling structure for filter testing. Background Technology

[0002] A filter is an optical element used to control the properties, wavelength, or intensity of light. It is usually made of transparent material and can selectively absorb or transmit certain wavelengths of light, thereby achieving spectral control in an optical system. In order to ensure the quality of filter products during the production process, image recognition inspection is required. Currently, high-definition recognition cameras are commonly used to achieve this. During the recognition process, tooling is required to position the filter to improve the inspection efficiency and reduce human error.

[0003] Chinese patent discloses a filter testing fixture (authorization announcement number CN222926390U). This patented technology improves and optimizes the existing filter testing fixture by designing limiting mechanisms on both sides of the stage on the basis of its original structure. These mechanisms can effectively press and limit the carrier plate placed in the loading slot, ensuring stability in the subsequent testing process and thus ensuring the testing effect. Moreover, the limiting mechanism is easy to operate, making it convenient for operators to pick up and put down the carrier plate after the testing is completed.

[0004] However, most existing filters are positioned using the reaction force of springs during inspection. Since springs are elastic elements, their stability is poor, affecting the positioning effect. Furthermore, the filters cannot be quickly disassembled and replaced after inspection, impacting inspection efficiency. For example, the aforementioned comparative document uses springs to position the filters. Therefore, those skilled in the art provide an auxiliary tooling structure for filter inspection to solve the problems mentioned in the background section. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary tooling structure for filter inspection that can solve the problems mentioned in the background art.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] An auxiliary tooling structure for filter inspection includes a processing table and a base symmetrically arranged at the end face of the lower surface of the processing table. A positioning plate is symmetrically arranged on the upper surface of the processing table, and a connecting rod is symmetrically arranged on the lower surface of the positioning plate. A lifting plate is connected to the lower end of the connecting rod, and an electric lifting rod is arranged at the middle position of the upper surface of the lifting plate.

[0008] A positioning plate is installed on one side of the processing table, and a moving groove is opened on the upper surface of the processing table. A screw rotates inside the moving groove, and a moving plate is threaded to the outside of the screw. A connecting plate is installed on the upper surface of the moving plate, and a cleaning box is provided on the upper surface of the connecting plate. Dust removal pipes are symmetrically arranged on the lower surface of the cleaning box, and an exhaust fan and a dust removal screen are provided inside the cleaning box.

[0009] The present invention is further configured such that: the fixed end of the electric lifting rod is installed at the middle position of the lower surface of the processing table, and the telescopic end of the electric lifting rod is connected to the upper surface of the lifting plate.

[0010] The present invention is further configured such that: the upper end of the connecting rod is fixed to the lower surface of the positioning plate, and the lower end of the connecting rod is fixed to the upper surface of the lifting plate; four connecting rods are symmetrically arranged on the lower surface of the positioning plate.

[0011] The present invention is further configured such that: a protective pad is provided on the lower surface of the positioning plate, and the material of the protective pad is rubber.

[0012] The present invention is further configured such that: the driving end of the positioning plate is connected to one end of the screw, a guide rod is provided inside the moving groove, and the moving plate is slidably mounted on the outside of the guide rod.

[0013] The present invention is further configured such that: at least six dust removal pipes are symmetrically arranged on the lower surface of the cleaning box, and an exhaust hole is provided on one side of the cleaning box.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This utility model discloses an auxiliary tooling structure for filter inspection. Through the arrangement of a positioning plate, a lifting plate, a connecting rod, an electric lifting rod, and a protective pad, the lifting plate rises and falls when the electric lifting rod is in operation. During this rising and falling, the positioning plate, connected by the connecting rod, descends to press and position the filter on the processing table. Simultaneously, the protective pad prevents damage to the filter. This structure is simple, easy to operate, and can assist in pressing the filter being inspected, facilitating subsequent inspection work.

[0016] This utility model relates to an auxiliary tooling structure for filter inspection. The operation of a motor causes a screw to rotate, and during rotation, a moving plate moves inside a moving slot. This allows adjustment of the position of the cleaning box on the connecting plate. The exhaust fan inside the cleaning box can suck up dust from the filter through a dust removal pipe, thus preventing contamination of the filter surface from affecting subsequent inspection work. This design is highly practical. Attached Figure Description

[0023] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-4 As shown, an auxiliary tooling structure for filter inspection includes a processing table 1 and a base 11 symmetrically arranged at the end face of the lower surface of the processing table 1. A positioning plate 2 is symmetrically arranged on the upper surface of the processing table 1, and a connecting rod 22 is symmetrically arranged on the lower surface of the positioning plate 2. The lower end of the connecting rod 22 is connected to a lifting plate 21. An electric lifting rod 23 is arranged at the middle position of the upper surface of the lifting plate 21. This arrangement uses the operation of the electric lifting rod 23 to make the lifting plate 21 rise and fall. During the rise and fall, the positioning plate 2 connected by the connecting rod 22 will move downward to position and press the substrate carrying the filter on the processing table 1 to ensure its stability.

[0025] A positioning plate 2 is installed on one side of the processing table 1, and a moving groove 12 is opened on the upper surface of the processing table 1. A screw 33 rotates inside the moving groove 12, and a moving plate 31 is threadedly connected to the outside of the screw 33. A connecting plate 32 is installed on the upper surface of the moving plate 31, and a cleaning box 4 is set on the upper surface of the connecting plate 32. Dust removal pipes 44 are symmetrically arranged on the lower surface of the cleaning box 4, and an exhaust fan 42 and a dust removal screen 41 are set inside the cleaning box 4. This arrangement uses the operation of the motor 3 to make the screw 33 rotate. When it rotates, the moving plate 31 moves because the screw 33 is threadedly connected to the moving plate 31. When it moves, the position of the cleaning box 4 can be adjusted to clean the filter.

[0026] like Figure 2 As shown, the fixed end of the electric lifting rod 23 is installed at the middle position of the lower surface of the processing table 1, and the telescopic end of the electric lifting rod 23 is connected to the upper surface of the lifting plate 21. The upper end of the connecting rod 22 is fixed to the lower surface of the positioning plate 2, and the lower end of the connecting rod 22 is fixed to the upper surface of the lifting plate 21. Four connecting rods 22 are symmetrically arranged on the lower surface of the positioning plate 2. This arrangement uses the operation of the electric lifting rod 23 to make the lifting plate 21 rise and fall. When rising and falling, the positioning plate 2 connected by the connecting rod 22 moves downward. When moving downward, the positioning plate 2 can position the substrate carrying the filter to ensure its stability.

[0027] like Figure 2 As shown, a protective pad 24 is also provided on the lower surface of the positioning plate 2. The material of the protective pad 24 is rubber. This arrangement allows the protective pad 24 to serve as a protective measure when the positioning plate 2 moves downward to press and position the substrate.

[0028] like Figure 3 As shown, the driving end of the positioning plate 2 is connected to one end of the screw 33. A guide rod is also provided inside the moving groove 12. The moving plate 31 is also slidably installed outside the guide rod. This setting uses the operation of the motor 3 to make the screw 33 rotate. Since the screw 33 is threadedly connected to the moving plate 31, the moving plate 31 will move outside the guide rod when the screw 33 rotates. This can automatically adjust the position of the cleaning box 4 to clean the filter.

[0029] like Figure 4 As shown, at least six dust removal pipes 44 are symmetrically arranged on the lower surface of the cleaning box 4. An exhaust port 43 is provided on one side of the cleaning box 4. This arrangement allows the surface of the filter to be cleaned when the exhaust fan 42 inside the cleaning box 4 is working, so as to facilitate subsequent testing.

[0030] The working principle of this utility model is as follows: When using the auxiliary tooling structure for filter detection, the substrate carrying the filter is placed on the processing table 1. After placement, the electric lifting rod 23 is activated, which causes the lifting plate 21 to rise and fall. During the rising and falling, the positioning plate 2 connected by the connecting rod 22 moves downward. When moving downward, the positioning plate 2 can press the substrate, and the protective pad 24 can protect the substrate, so as to facilitate subsequent detection by a high-definition recognition camera.

[0031] Before testing, the operation of motor 3 will cause screw 33 to rotate, and during rotation, moving plate 31 will move inside moving slot 12. This allows adjustment of the position of cleaning box 4 on connecting plate 32. The exhaust fan 42 inside cleaning box 4 can suck up dust on the filter through dust removal pipe 44, thus avoiding contamination on the filter surface that could affect subsequent testing. This method is highly practical.

[0032] All electrical devices used in this invention are existing and known, and are connected to an external main controller and power supply. The main controller can be a conventional and known device such as a computer, and can be purchased and used directly on the market. Its structure, circuit and control principle are all existing and known technologies. Therefore, the structure, circuit and control principle of the device are not described in detail here.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
