DETAILED DESCRIPTION

[0025] like Figure 1 and Figure 2 As shown, the utility model provides an MLED module processing fixture, including a supporting body, the supporting body is provided with a vacuum chamber 1 which opens upward, a suction hole 9 is provided in the vacuum chamber 1, a sealing module 6 is provided at the opening edge of the vacuum chamber 1, a bottom plate 8 is provided at the bottom of the vacuum chamber 1, and a supporting block 5 is provided on the bottom plate 8.

[0026] By setting an upwardly open vacuum chamber 1 and a suction hole 9 inside the support body and equipping it with a sealing module 6, the MLED module placed on the vacuum chamber 1 is firmly adsorbed, effectively avoiding displacement during processing, and improving processing accuracy and efficiency. By setting a support block 5, precise position support can be further provided for the central area of ​​the module to ensure processing stability and avoid components already installed on the module.

[0027] Furthermore, the bottom plate 8 can be fixed to the bottom of the vacuum chamber 1 by a plurality of fasteners 7 , and preferably four fasteners 7 are arranged at four corners for fixing.

[0028] A specific method of fixing the support block 5 on the bottom plate 8 is as follows: the bottom plate 8 is a magnetically conductive plate such as a steel plate with magnetic conductivity, and the support block 5 is a permanent magnet, so that the support block 5 can be directly adsorbed on the bottom plate 8 .

[0029] Alternatively, the bottom plate 8 may be a permanent magnetic plate or an electromagnetic plate, and the support block 5 may be made of a magnetic conductive material. When the electromagnetic plate is powered, magnetic attraction may be generated, and the support block 5 may be placed on the bottom plate 8 to produce an adsorption effect.

[0030] Preferably, a flexible pad is provided on the top of the support block 5. By adding a flexible pad on the top of the support block 5, the pressure acting on the MLED module can be effectively buffered and evenly distributed, and the vibration generated by processing can be absorbed, etc., to prevent damage caused by displacement of the module due to local force during processing, protect the contact surface of the module, and improve the yield rate and processing quality of the module.

[0031] Furthermore, the height of the support block 5 plus the flexible pad is equal to or slightly higher than the edge of the vacuum chamber 1. The flexible pad is made of rubber or flexible plastic and the MLED module can be placed on it to provide support. The MLED module generally has electrical components such as ICs, and the electrical components on the module can be avoided by simply moving the support block 5.

[0032] Preferably, at least three support columns 2 are installed at the bottom of the support body, and the bottom of the support column 2 is installed on the base 3. Furthermore, the base 3 is provided with a mounting position that cooperates with the processing machine tool. Specifically, the mounting position can be a groove of standard size or a mounting step, etc. After being placed on the processing machine tool, the base 3 can be fixed to the workbench of the machine tool with a universal clamp. The setting of the support column 2 also allows the suction hole 9 to be set at the bottom of the vacuum chamber 1, and the pipeline can be passed through the gap between the support columns 2.

[0033] The setting of the support column 2 can increase the height of the entire fixture, and cooperate with the Z-axis motion range of the CNC machine tool to make the upper platform of the fixture within a suitable cutting range. Furthermore, the support column 2 can be set to a replaceable installation form, which is convenient for rapid positioning and replacement of the fixture on different machine tools, thereby improving production efficiency and flexibility.

[0034] The mounting position on the base 3 specifically refers to a preset precise positioning structure, which can be quickly and accurately docked with the processing machine tool to ensure the consistency of each installation position, simplify the preparation of the fixture, reduce the machine tool adjustment time, and further improve the processing efficiency and the stability of product quality.

[0035] A supporting protrusion for supporting the MLED module is arranged on the edge of the upper surface of the supporting body toward the opening direction of the vacuum chamber 1 , and a supporting step is arranged on the side of the supporting protrusion toward the vacuum chamber 1 , and the height of the supporting step is equal to the height of the edge of the vacuum chamber 1 .

[0036] The design of support protrusions and support steps provides multi-point support for the MLED module, ensuring that the module is evenly stressed along the entire edge. Combined with the equal height design, it effectively prevents stress concentration during processing, protects the electronic components at the edge of the module, and improves the stability and safety of processing.

[0037] Preferably, the support protrusions are evenly arranged along the edge of the upper surface of the support body, and a chip groove 4 is formed between the support protrusions and between the support protrusions and the edge of the vacuum chamber 1. By providing the chip groove 4 and the evenly arranged support protrusions and slots, the effective discharge of cutting chips during the processing is achieved, the influence of chip accumulation on the processing accuracy and the pollution of the module are avoided, the cleanliness of the processing area is maintained, and the service life of the fixture is extended.

[0038] Preferably, the sealing module 6 comprises a mounting groove arranged along the upper edge of the vacuum chamber 1 , a sealing ring support frame corresponding to the shape of the MLED module is installed on the mounting groove, and a sealing ring is installed on the sealing ring support frame.

[0039] The sealing module 6 includes an installation groove precisely set along the upper edge of the vacuum chamber 1. The installation groove is designed to cooperate with the modular replacement design. Sealing ring support frames and sealing rings of different shapes and sizes are replaced corresponding to different MLED modules to ensure the best sealing effect, so that the support frame can accurately match the different contours and curves of the MLED module.

[0040] Furthermore, in order to save costs, replaceability may not be considered. If only one type of MLED module is processed, the sealing module 6 may only include a mounting groove and a sealing ring. The sealing ring may be embedded in the mounting groove to achieve a sealing effect.

[0041] The material of the sealing ring support frame is selected from high-performance engineering plastics or metal alloys that are resistant to high temperatures and corrosion, ensuring that good morphological stability and sealing can be maintained in a long-term vacuum operating environment. The sealing ring is made of wear-resistant, highly elastic silicone rubber or fluororubber. In view of the slight changes in the contact surface of the MLED module, the sealing ring is designed to have a special cross-sectional shape with adaptive deformation capabilities, such as a corrugated or trapezoidal cross-section, to enhance the tightness and flexibility of the sealing contact.

[0042] During operation, after installing the base 3 on the working platform of the machine tool, first adjust the adsorption position of the support block 5 on the bottom plate 8 corresponding to the position of the components on the MLED module to avoid the components from being crushed, and then place the MLED module on the sealing ring of the vacuum chamber 1 to ensure that the parts of the module to be processed are all outside the range of the vacuum chamber 1, and place the edge of the module on the supporting step of the supporting protrusion. During processing, waste materials can slide out through the chip groove 4. Furthermore, the chip groove 4 can be set to be inclined toward the side away from the vacuum chamber 1, so that the waste materials can slide out easily.

[0043] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
