[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0025] Please refer to Figs. 1-3 The vacuum adsorption fixing platform structure comprises:
[0026] The vacuum connection platform 1 is provided with a plurality of groups of vacuum connection channels 11, and the product adsorption platform 2 is provided with a plurality of groups of product adsorption holes 21, and the vacuum connection channels 11 and the product adsorption holes 21 are arranged one by one in correspondence.
[0027] The throttle partition plate 3 is arranged between the vacuum connection platform 1 and the product adsorption platform 2, and the throttle partition plate 3 is provided with a plurality of throttle holes 31 arranged one by one in correspondence with the product adsorption holes 21.
[0028] The vacuum adsorption fixing platform structure has a plurality of groups of vacuum connection channels 11 to form a plurality of vacuum paths, can create adsorption force at different positions, so as to adapt to products of various shapes and specifications, the product adsorption platform 2 is located above the vacuum connection platform 1, the product adsorption holes 21 are arranged to enable the platform to adsorb products in a limited area, improve the accuracy and efficiency of product positioning in the production process, the throttle partition plate 3 is arranged between the adsorption holes and the vacuum connection channels 11, air flow management is enhanced, air flow instability is effectively avoided, and adsorption capacity and production efficiency are further improved.
[0029] And by increasing the throttle partition plate 3 between the vacuum connection platform 1 and the product adsorption platform 2, stable adsorption effect can be achieved without using a false body to cover the adsorption hole when the product is not full, which is convenient for subsequent use.
[0030] As Figs. 2-3 The diameter of the throttle hole 31 is smaller than the diameter of the product adsorption hole 21, the design of the throttle hole 31 is coordinated with the diameter of the product adsorption hole 21, and the diameter of the throttle hole 31 is designed to be smaller than the diameter of the product adsorption hole 21. The purpose of this design is to reduce the passing area of the air flow, so that sufficient adsorption force can be formed in the vacuum adsorption process even if part of the product is not covered, so as to maintain the stable adsorption of the product. This improvement will greatly reduce the risk of adsorption failure caused by the fact that the adsorption hole is not covered by the product, thereby improving the reliability of the production process.
[0031] AsFig. 3 As shown, the product adsorption hole 21 has a hole diameter of 0.5-2mm, and the throttle hole 31 has a hole diameter of 0.05-0.2mm. Preferably, the product adsorption hole 21 has a hole diameter of 1.2mm, and the throttle hole 31 has a hole diameter of 0.15mm. In a specific design implementation, the product adsorption hole 21 has a hole diameter ranging from 0.5mm to 2mm, which is flexible to adapt to the needs of different components; and the throttle hole 31 has a hole diameter ranging from 0.05mm to 0.2mm. This parameter configuration ensures that the product adsorption hole 21 can provide strong adsorption force under normal working conditions, and the throttle hole 31 limits the flow of gas to ensure the stability and controllability of the gas flow, thereby improving the overall working efficiency and stability of the equipment.
[0032] In actual use, the standard hole diameter of the product adsorption hole 21 is set to 1.2mm, and the hole diameter of the throttle hole 31 is 0.15mm, forming ideal adsorption force and gas flow characteristics. This specific value setting takes into account the volume and weight of common electronic components, ensuring that small components can be effectively adsorbed and prevented from moving during the adsorption process under normal working conditions, while avoiding adsorption failure caused by unstable gas flow, thereby improving the overall efficiency of the production line.
[0033] As shown in Fig. 3 The product adsorption platform 2 is also provided with a buffer gas chamber 22 connected to the product adsorption hole 21 for gas flow buffering, and the inner diameter of the buffer gas chamber 22 is greater than the hole diameter of the product adsorption hole 21. The buffer gas chamber 22 provided on the product adsorption platform 2 includes a structure design connected to the product adsorption hole 21, which provides buffering for changes in gas flow. This design effectively reduces the gas flow impact that may occur during rapid adsorption or operation changes, improving the safety and stability of the adsorption system and preventing products from being affected by sudden gas flow during the adsorption process, which is particularly important for precision electronic components.
[0034] At the same time, the inner diameter of the buffer gas chamber 22 is set to be greater than the hole diameter of the product adsorption hole 21, so that a uniform gas flow distribution can be created when the gas flows through the buffer chamber. This design not only helps to reduce the sudden change of gas flow speed, but also improves the stability of the gas flow when it reaches the adsorption hole, greatly improving the adsorption effect and ensuring that the product can be stably adsorbed under various working conditions.
[0035] As shown in Figs. 1-2As shown, multiple sets of vacuum connection channels 11 are interconnected and connected to the vacuum equipment through vacuum tubes 4. In the design of the vacuum connection channels 11, multiple vacuum connection channels 11 are interconnected and connected to the vacuum equipment through vacuum tubes 4. This structural design enables the entire adsorption system to provide uniform attractive force in different areas and quickly respond to changes in product placement during the production process, improving the flexibility and efficiency of production. In addition, the centralized management of the vacuum equipment also simplifies the maintenance procedures and reduces the difficulty of operation.
[0036] like Figs. 1-3 As shown, the product adsorption holes 21 are arranged in a grid pattern, and the cross-sectional shape of the product adsorption holes 21 and the throttling holes 31 is circular.
[0037] This grid-like layout design ensures that the distance between each product adsorption hole 21 is evenly distributed, ensuring that each element can obtain equal adsorption force during the adsorption process. In addition, this method also helps to reduce local density differences in the vacuum system during operation, thereby improving the overall adsorption efficiency and the working stability of the equipment.
[0038] In addition, the cross-sectional shape of the product adsorption hole 21 and the throttling hole 31 is circular. This design choice ensures the linearity of the flow when the airflow passes through, effectively reduces the generation of turbulence, and ensures that the ideal airflow state is maintained at all times during the vacuum adsorption process. This shape choice not only improves production efficiency, but also reduces the wear and maintenance frequency of the equipment to a certain extent.
[0039] The throttling baffle 3 is either a laser-drilled plate or a powder sintered plate. Laser drilling technology allows for high-precision setting of hole diameter and hole spacing, while powder sintered plates have excellent strength and durability. The choice of these two materials enables the throttling baffle 3 to maintain stable performance even in high-intensity working environments, and can better meet the stringent requirements of chip manufacturing equipment for high reliability and long static operation.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
