Utility Model Content

[0004] This invention provides a diffuser switching device that improves efficiency and automation, ensures safe switching operations for non-professional personnel, and avoids process quality problems such as rework caused by manual calibration deviations.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a diffuser switching device, including a track mounting base, a first drive component mounted sideways in the mounting groove of the track mounting base, one end of the first drive component being fixedly connected to the slide plate on the other side of the track mounting base via a connecting plate assembly; a plurality of mounting blocks are provided on the slide rail on the upper surface of the slide plate, the mounting blocks at both ends being connected to the second drive component respectively, and a hopper mounting base is provided above the mounting blocks; a plurality of lens alignment blocks are provided between the mounting blocks, and alignment connecting blocks fixedly connected to the slide plate are provided between the plurality of lens alignment blocks. Through a solenoid valve and operation via a human-machine interface, the gas flow is determined, causing the first and second drive components to move and push. The first drive component is used to change the downlight illumination chamber, and the second drive component is used to change the lens alignment blocks. The operation is completed by cooperating with the human-machine interface to complete the operation with different specifications of lens positioning blocks, facilitating quick operation for unskilled personnel. Based on this rapidly switchable DLHousing diffuser switching device, it can maximize personnel safety, convenience, efficiency, and work quality.

[0006] Preferably, the first drive assembly has several mounting posts on its side, which extend into the mounting groove. The first drive assembly is horizontally positioned, with one end connected to a vertically positioned first connecting plate. Two mounting posts are fixedly installed in the mounting groove. A T-shaped plate is connected to the drive section of the first drive assembly. One end of the T-shaped plate is connected to the first drive assembly, and the other end is fixedly installed on the track mounting base for securing the first drive assembly. Through the cooperation of the mounting posts and the mounting groove, as well as the fixing structure of the T-shaped plate, the first drive assembly is securely installed on the track mounting base, preventing loosening due to vibration or external forces during operation. This improves the stability and reliability of the device, extends its service life, and provides a solid foundation for subsequent drive actions, ensuring operational accuracy.

[0007] Preferably, a horizontally positioned second connecting plate is connected to the top of the first connecting plate. The second connecting plate spans across the top of the track mounting base, with one end connected to the first connecting plate and the other end connected to the slide plate. The first connecting plate is located on one side of the T-shaped plate, and the second connecting plate is a triangular plate, with one end connected to the top of the side of the slide plate closest to the track mounting base. The mutually perpendicular arrangement of the first and second connecting plates allows the first drive assembly to drive the slide plate located on the other side of the track mounting base to move.

[0008] Preferably, the slide plate has several first sliders on the side closest to the track mounting base, and a guide rail is installed in the mounting groove on the side of the track mounting base closest to the slide plate. The first sliders are slidably mounted on the guide rail of the track mounting base. The slide plate is T-shaped, and its plane is parallel to the track mounting base. Three mounting grooves are linearly provided along the entire length of each of the two sides of the track mounting base for mounting the guide rail and mounting posts. The guide rails are respectively located in the upper and lower mounting grooves on the side of the track mounting base closest to the slide plate. Through the sliding engagement of the first sliders and the guide rails, the movement of the slide plate on the track mounting base is smoother and more precise, reducing friction and wear, and improving the flexibility and reliability of sliding. At the same time, the T-shaped slide plate design increases its structural strength, prevents deformation during movement, ensures the stability and consistency of the device during long-term use, and further improves work quality and efficiency.

[0009] Preferably, the upper surface of the slide plate is provided with a slide rail, on which several second sliders are slidably mounted. The upper part of the second sliders is fixedly connected to the mounting block. The alignment connecting block is L-shaped and is located in the middle of several lens alignment blocks. One end is fixedly connected to the side of the slide plate near the track mounting seat. When the first drive component drives the slide plate to slide, the alignment connecting block drives the upper downlight cover compartment to move, thereby realizing the replacement of the compartment. This structural design allows the mounting block to move flexibly on the slide plate, facilitating quick adjustment of the mounting block's position according to actual needs, thus enabling rapid replacement of downlight cover compartments of different specifications. At the same time, the L-shaped alignment connecting block ensures stable driving of the downlight cover compartment during the drive process, avoiding shaking or detachment caused by unstable connection, further improving the reliability and operation quality of the device, and reducing the risk of rework due to errors in the replacement process.

[0010] Preferably, several lens alignment blocks are provided between two mounting blocks near the connecting plate assembly, and these lens alignment blocks are positioned on the side of the hopper mounting base near the slider. The upper surface of the alignment connecting block has rectangular blocks at both ends, adapted to the shape of the other lens alignment blocks. Through the cooperation between the lens alignment blocks and the mounting blocks, and the adaptable design of the rectangular blocks on the alignment connecting blocks, stable installation and precise positioning of the lens alignment blocks between the mounting blocks can be ensured, facilitating the rapid replacement of lenses of different specifications. This structural optimization further improves the automation and convenience of the device, reduces the complexity and error of manual operation, and enhances overall operational efficiency and quality.

[0011] Preferably, the mounting blocks are L-shaped. A number of mounting blocks are grouped in pairs, and there is a silo mounting seat above each group of mounting blocks. Above the silo mounting seat is installed the barrel lamp cover silo. Bolts are provided on both sides of the lower surface of the silo mounting seat outside the mounting blocks. The design of the L-shaped mounting blocks can provide stable support and firm fixation for the silo mounting seat, ensuring the stability of the barrel lamp cover silo during operation. This structural optimization can effectively avoid potential safety hazards and quality problems caused by the loosening or falling off of the barrel lamp cover silo.

[0012] Preferably, the first driving component and the second driving component are cylinders. The lower part of the second driving component is arranged at both ends of the slide rail through a mounting plate. There is a circular hole at the upper end of the mounting plate for fixedly installing the second driving component, and a rectangular hole at the lower end for passing through the slide rail. Using cylinders as the driving components can provide stable and powerful driving force, with fast response speed and high control precision, meeting the requirements of rapid switching operations. At the same time, through the cooperation of the mounting plate and the slide rail, it can ensure the stable installation and flexible movement of the second driving component on the slide rail, further improving the automation level and operation efficiency of the device, reducing the labor intensity and error of manual operation, and enhancing the overall performance.

[0013] Preferably, one mounting block in each group of mounting blocks and one mounting block in another group are connected with a U-shaped block, and the U-shaped blocks are cross-arranged. The U-shaped blocks are used to connect different barrel lamp cover silos, and driving one barrel lamp cover silo by the slider can drive another barrel lamp cover silo. This cross-connection structure of U-shaped blocks can achieve the linkage between multiple barrel lamp cover silos. By driving one barrel lamp cover silo, other barrel lamp cover silos can be driven to move synchronously, greatly improving the collaborative operation ability of the device, reducing the number and complexity of the driving components, lowering the cost, while improving the operation efficiency and synchronism, and ensuring the stability and consistency of the device during multi-station operations.

[0014] Preferably, one end of the second driving component and the side wall of the mounting block are connected through a floating joint, and the mounting plate is slidably installed on the slide rail. The use of the floating joint can automatically compensate for the small deviation between the mounting block and the driving component, ensuring the stability and reliability of the connection, and avoiding failures or damages caused by insecure connection or excessive deviation.

[0015] The beneficial effects of the present utility model are as follows: It ensures the safety of non-professional personnel during the lifting and switching operation, improves efficiency, automation and convenience, and avoids process quality problems such as secondary rework caused by manual calibration deviation.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] In modern industrial production, the demand for efficient, safe, and precise operation of various equipment is increasing. Especially in scenarios involving diffuser switching, traditional manual operation methods are not only inefficient but also prone to causing numerous process quality problems, such as rework, due to manual calibration deviations. The diffuser switching device provided by this invention is meticulously designed to address these industry pain points, aiming to significantly improve operational efficiency, achieve automated operation, and ensure that even non-professionals can safely and conveniently complete the switching operation.

[0022] like Figure 1 and Figure 2As shown, the track mounting base serves as the fundamental support structure of the entire device, bearing other key components and providing a stable platform for subsequent driving and switching operations. The first drive component is mounted sideways in the mounting slot of the track mounting base. One end of the first drive component is fixedly connected to the slide plate on the other side of the track mounting base via a connecting plate assembly. This connection method allows the first drive component to drive the slide plate to move precisely on the track mounting base. In actual operation, controlled by a solenoid valve and operated through a human-machine interface, the first drive component will act according to the command after determining the gas supply. It is mainly responsible for the replacement of the downlight illumination chamber, and its driving process is stable and precise, effectively avoiding the deviations and instabilities that may occur in traditional manual replacement methods. Several mounting blocks are set on the slide rail on the upper surface of the slide plate. These mounting blocks act as flexible carriers, providing diverse possibilities for the functional realization of the entire device. The mounting blocks at both ends are connected to the second drive component, and a hopper mounting base is set above the mounting blocks for installing the downlight illumination chamber. Several lens alignment blocks are cleverly arranged between the mounting blocks, and between these lens alignment blocks, there are alignment connecting blocks fixedly connected to the slide plate. Upon receiving commands from the human-machine interface, the second drive component also operates under the influence of gas flow, primarily responsible for replacing the lens alignment blocks. With the assistance of the human-machine interface, lens positioning blocks of different specifications can be replaced quickly and accurately. This allows even unskilled personnel to quickly become familiar with and operate the device, greatly improving the convenience and efficiency of the operation.

[0023] like Figure 2 As shown, the first drive assembly has several mounting posts on its side. In this embodiment, there are two mounting posts that extend into the mounting groove and are fixedly installed therein. This tight fit between the mounting posts and the mounting groove acts like a sturdy "anchor point" for the first drive assembly, making its installation on the track mounting base extremely stable. The first drive assembly is horizontally positioned, with one end connected to a vertically positioned first connecting plate. Its drive section is also connected to a T-shaped plate, one end of which is connected to the first drive assembly, while the other end is firmly fixed to the track mounting base. This multi-layered fixing structure ensures that the first drive assembly will not loosen during the entire operation, even under vibration or other external forces. This not only improves the stability and reliability of the device and extends its service life, but also lays a solid foundation for subsequent precise drive actions, ensuring operational accuracy. For example, in some optical product production lines with extremely high precision requirements, the stable installation of the first drive assembly can ensure that the replacement error of the downlight illumination chamber is controlled within a very small range, avoiding illumination deviations caused by loose installation, thereby guaranteeing product quality.

[0024] like Figure 2 and Figure 3As shown, a horizontally positioned second connecting plate is connected to the top of the first connecting plate. The second connecting plate is triangular in shape and spans across the top of the track mounting base, connecting one end to the first connecting plate and the other end to the sliding plate. The first connecting plate is positioned on one side of the T-shaped plate. This ingenious arrangement of the mutually perpendicular first and second connecting plates creates an efficient force transmission structure. This allows the first drive assembly to smoothly drive the sliding plate located on the other side of the track mounting base. In actual operation, the driving force generated by the first drive assembly is transmitted through the first connecting plate to the second connecting plate, and then precisely transmitted from the second connecting plate to the sliding plate, achieving smooth and precise movement of the sliding plate on the track mounting base, providing strong support for subsequent operations such as hopper replacement.

[0025] like Figure 1 and Figure 3 As shown, the slide plate has several first sliders on one side near the track mounting base. Correspondingly, a guide rail is installed in the mounting groove on the side of the track mounting base near the slide plate. The first sliders are slidably mounted on the guide rail of the track mounting base. The slide plate is T-shaped, and its plane is parallel to the track mounting base. Three mounting grooves are linearly arranged along the entire length of each side of the track mounting base for mounting the guide rail and mounting posts. The guide rails are respectively located in the upper and lower mounting grooves on the side of the track mounting base near the slide plate. The sliding engagement of the first sliders with the guide rails is like installing smooth "wheels" for the slide plate, making its movement on the track mounting base exceptionally smooth and precise. This engagement not only reduces friction and wear during slide plate movement but also improves sliding flexibility and reliability. Simultaneously, the T-shaped slide plate design significantly increases its structural strength, allowing it to remain stable even during frequent movements and preventing deformation. This ensures the stability and consistency of the device during long-term use, further improving operational quality and efficiency. In production scenarios where frequent hopper changes are required, the stable sliding mechanism and high-strength structure of the slide plate ensure the accuracy and efficiency of each change operation, reducing production downtime caused by slide plate issues.

[0026] like Figure 2As shown, the upper surface of the slide plate is equipped with a slide rail, on which several second sliders are slidably mounted. In this embodiment, four second sliders are preferred, and the upper part of the second sliders is fixedly connected to the mounting block. This design allows the mounting block to move flexibly on the slide plate, and the operator can quickly adjust the position of the mounting block according to actual work needs. For example, when it is necessary to replace downlight cover boxes of different specifications, the position of the box mounting seat can be quickly adjusted by sliding the mounting block, realizing the rapid replacement of downlight cover boxes of different specifications. At the same time, the alignment connecting block is L-shaped and is set in the middle of several lens alignment blocks, with one end fixedly connected to the side of the slide plate near the track mounting seat. When the first drive component drives the slide plate to slide, it will drive the downlight cover box above to move through the alignment connecting block, thereby realizing the replacement of the box. The setting of the L-shaped alignment connecting block can ensure the stable driving of the downlight cover box during the driving process, avoiding shaking or falling off due to unstable connection, further improving the reliability of the device and the quality of operation, and reducing the risk of rework caused by errors in the replacement process. Several lens alignment blocks are positioned between two mounting blocks near the connecting plate assembly, located on the side of the hopper mounting base closest to the slider. Rectangular blocks are located at both ends of the upper surface of the alignment connecting block, their shapes adapted to the shapes of the other lens alignment blocks. Through the tight fit between the lens alignment blocks and the mounting blocks, and the adaptable design of the rectangular blocks on the alignment connecting blocks, stable installation and precise positioning of the lens alignment blocks between the mounting blocks are ensured. In actual operation, when it is necessary to replace lenses of different specifications, the operator can control the second drive assembly through the human-machine interface to quickly complete the lens alignment block replacement. This structural optimization greatly improves the automation and convenience of the device, reduces the complexity and error of manual operation, and improves overall work efficiency and quality. For example, when producing different models of lamps, quick replacement of lens alignment blocks can rapidly adapt to the production needs of different products, improving production efficiency. This device is suitable for products with 3-inch, 3.5-inch, 4-inch, 5-inch, and 6-inch wafers.

[0027] like Figure 2 As shown, the mounting blocks are designed in an L-shape, with several blocks arranged in pairs. A hopper mounting seat is located on top of each pair of blocks, and the downlight cover hopper is mounted on top of the hopper mounting seat. Bolts are located on both sides of the lower surface of the hopper mounting seat on the outer side of the mounting block. The L-shaped mounting block design provides stable support and a firm fixation for the hopper mounting seat, ensuring the stability of the downlight cover hopper during operation. During device operation, whether subjected to rapid driving movements or minor vibrations from the external environment, the L-shaped mounting blocks firmly secure the hopper mounting seat, effectively preventing safety hazards and quality problems caused by the downlight cover hopper loosening or falling off.

[0028] like Figure 1 and Figure 2As shown, both the first and second drive components use cylinders as drive elements. Cylinders offer numerous advantages: they provide stable and powerful driving force, respond extremely quickly to control signals, and offer high control precision, meeting the stringent requirements of rapid operation switching. The second drive component is mounted on both ends of the slide rail via mounting plates. The upper end of the mounting plate has a circular hole for fixing the second drive component, and the lower end has a rectangular hole for the slide rail to pass through. The cooperation between the mounting plate and the slide rail ensures the stable installation and flexible movement of the second drive component on the slide rail. In actual operation, the efficient drive of the cylinders allows for the replacement of the lens alignment block and the downlight illumination chamber in a short time, greatly improving the automation level and operational efficiency of the device, reducing the labor intensity and errors of manual operation, and enhancing the overall performance of the device. For example, in large-scale lighting production lines, the rapid response of cylinder drives can meet the high-efficiency operation requirements of the production line, improve production efficiency, and reduce production costs.

[0029] like Figure 1 As shown, one mounting block in each group is connected to one mounting block in another group by a U-shaped block, with the U-shaped blocks arranged in a crisscross pattern. The main function of the U-shaped blocks is to connect different downlight cover compartments, so that when the slider drives one downlight cover compartment, it can drive another downlight cover compartment. In this embodiment, two downlight cover compartments are preferably set. This U-shaped block cross-connection structure realizes the linkage between multiple downlight cover compartments. By driving one downlight cover compartment, the other downlight cover compartments can be moved synchronously. This design greatly improves the collaborative operation capability of the device, reduces the number and complexity of drive components, and lowers costs. At the same time, it improves work efficiency and synchronization, ensuring the stability and consistency of the device when operating in multiple stations. In some work scenarios that require the simultaneous replacement of multiple downlight cover compartments, the U-shaped block linkage structure can quickly and accurately complete the synchronous replacement of multiple compartments, improving work efficiency and reducing work time.

[0030] like Figure 1 As shown, one end of the second drive assembly is connected to the side wall of the mounting block via a floating joint, and the mounting plate is slidably mounted on the slide rail. The use of the floating joint is a key optimization of this device, as it automatically compensates for minor deviations between the mounting block and the drive assembly. During device operation, minor positional deviations may occur between the mounting block and the drive assembly due to factors such as manufacturing precision, assembly errors, and wear after prolonged use. The floating joint effectively accommodates these deviations, ensuring the stability and reliability of the connection and preventing malfunctions or damage caused by loose connections or excessive deviations. This design further improves the reliability and service life of the device, ensuring the continuity and stability of operation.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
