Description

Technical Field

[0001] The utility model belongs to the field of mechanical technology and relates to a fixture, in particular to a positioning device and processing equipment capable of adjusting the vacuum area. Background Art

[0002] In the existing mechanical processing technology, positioning devices, especially vacuum positioning devices, are widely used in various precision processing fields, including semiconductor manufacturing, assembly of precision electronic components and processing of complex mechanical parts. These positioning devices mainly use the principle of vacuum adsorption to fix the workpiece, and generate negative pressure by extracting the air in the vacuum chamber, so that the workpiece can be firmly adsorbed on the device to ensure the accuracy and efficiency of the processing process.

[0003] However, traditional vacuum positioning devices have several shortcomings:

[0004] The vacuum area is fixed and cannot be adjusted: The vacuum adsorption area of ​​the traditional device is fixed and cannot be adjusted according to workpieces of different sizes or shapes, which limits its flexibility and extensiveness of application. For workpieces of non-standard sizes, too large or too small adsorption area may lead to loose adsorption or low processing efficiency;

[0005] Single vacuum channel: Most positioning devices only have a single vacuum channel, which means that once part of the channel is blocked or damaged, the stability and reliability of the entire vacuum system will be affected. In addition, a single channel cannot achieve fine control of the adsorption force and cannot meet the specific requirements of a specific workpiece for the adsorption force;

[0006] Lack of effective filtering mechanism: During the vacuuming process, dust and other tiny particles may be sucked in with the air, blocking the air valve or damaging the vacuum pump. The existing technology often lacks effective filtering measures to prevent this problem, reduce the maintenance cost of the equipment and increase its service life;

[0007] Complex assembly and maintenance: Existing positioning devices mostly adopt fixed assembly methods. Once maintenance or replacement of parts is required, the whole process is cumbersome and complicated, especially on continuous production lines. This design significantly increases downtime and maintenance costs.

[0008] In the improvement of vacuum fixtures, a vacuum platform fixture and vacuum adsorption device with application number 202322336162.X, which relates to the field of vacuum adsorption technology, includes a base, and a plurality of vacuum adsorption holes are provided on one side surface of each base for adsorbing substrates, and a confluence cavity is also provided on each of the bases, and each of the confluence cavities is connected to a plurality of vacuum adsorption holes, and a hollow groove opening downward is provided on the other side surface of each of the bases, and each of the hollow grooves is used to fit into a heating device, and each of the confluence cavities is located at the top of each of the hollow grooves. Compared with the prior art, the vacuum platform fixture provided by the utility model can be directly attached to the heating device, so as to achieve rapid heating of the fixture and the substrate and improve the working efficiency.

[0009] However, the above technical solution has the following shortcomings: the multiple vacuum adsorption holes are simple through-hole structures, that is, they can enable airflow to flow in both directions. Only when all vacuum adsorption holes are sealed and covered can the vacuum adsorption product be achieved. Therefore, the above technical solution can only adsorb and fix workpieces of one size, which lacks flexibility and has application limitations. In addition, the base of the above technical solution is designed with multiple vacuum adsorption holes and heat dissipation grooves, which makes cleaning and maintenance more complicated and the risk of blockage may increase. In addition, the complex internal channels may require special tools and procedures for maintenance. Utility Model Content

[0010] The purpose of the utility model is to solve the above problems in the prior art and to propose a positioning device and processing equipment capable of adjusting the vacuum area.

[0011] The purpose of the utility model can be achieved through the following technical solutions: a positioning device with adjustable vacuum area, including a vacuum chamber, on which a plurality of one-way air valves connected to the vacuum chamber are arranged, the plurality of one-way air valves form a plurality of independent exhaust channels, a pad is provided on the plurality of one-way air valves, the pad opens a plurality of connecting holes corresponding to the plurality of one-way air valves one by one, a jig carrier is provided on the pad, the jig carrier opens a plurality of adsorption holes corresponding to the plurality of connecting holes one by one, the one-way air valves, the connecting holes and the adsorption holes form a separately sealed one-way exhaust pipeline.

[0012] The design of using several independent single-way air valves allows precise control of the area covered by each air valve to achieve local exhaust function. The main advantage of this design is that the exhaust state of each independent area can be adjusted according to the size and shape of the workpiece, or the specific part required for processing, so as to achieve higher work efficiency and better processing quality. The independent operation of each air valve also helps to reduce the energy consumption of the entire system.

[0013] The configuration of the one-way air valve, connecting hole and adsorption hole is designed as a continuous and closed process to form an independent air extraction path. The one-way air valve ensures that the air flow can only flow in one direction, that is, from the adsorption hole to the vacuum equipment. The outlet of each air valve is connected to a connecting hole, and each connecting hole corresponds to one or more adsorption holes under it, which are located on the fixture carrier. This structural layout ensures that the air flow from the adsorption hole to the vacuum equipment is closed and independent, preventing air leakage or cross contamination, thereby improving the air extraction efficiency and working effect.

[0014] Preferably, the vacuum chamber comprises a gas storage plate, the interior of the gas storage plate has a vacuum inner cavity, a plurality of exhaust holes are arranged on the top of the gas storage plate, and the plurality of exhaust holes are connected to the vacuum inner cavity.

[0018] Preferably, a filter copper sheet is provided on the air extraction top port of the one-way air valve.

[0019] The main purpose of installing a copper filter on the top of the single-way air valve is to prevent dust, particulate matter or any possible contaminants from entering the air valve, which is essential for keeping the system clean and preventing the air valve from clogging. The copper filter not only has good mechanical strength, corrosion resistance and thermal conductivity, but also has natural antimicrobial properties, which can reduce maintenance problems caused by the growth of bacteria or other microorganisms. In addition, the copper filter can also serve as a primary filter layer to protect deeper system components from damage, thereby extending the service life and maintenance cycle of the equipment.

[0020] Preferably, the plurality of one-way exhaust pipelines are arranged in a matrix.

[0021] Preferably, a main exhaust port is provided on the vacuum chamber, and the main exhaust port is connected to an exhaust device via an exhaust hose.

[0022] A processing equipment comprises the above positioning device with adjustable vacuum area.

[0023] Compared with the prior art, the positioning device and processing equipment with adjustable vacuum area have the following beneficial effects:

[0024] 1. Enhanced adjustment flexibility: The utility model forms a separately controllable air extraction path by setting a number of single-way air valves in the vacuum chamber and covering each air valve with a pad and a fixture carrier. This design allows the user to adjust the adsorption area according to processing requirements and achieve accurate positioning and fixation of workpieces of different sizes and shapes. This flexible adjustment function enables the equipment to cope with changing production requirements and improves the versatility and applicability of the equipment.

[0025] 2. Optimized air extraction efficiency: Each single-way air valve of the equipment is designed with a filter copper sheet, which not only protects the air valve from impurities and prolongs its service life, but also improves the purity and efficiency of air extraction. The setting of the single-way air valve ensures the unidirectionality of the air flow and avoids air backflow, thereby speeding up the air extraction speed and reducing energy consumption;

[0026] 3. Improve processing accuracy and quality: The matrix arrangement of the one-way exhaust pipeline allows for even and effective distribution of the exhaust force, ensuring that the workpiece is stably fixed during the processing. This uniform pressure distribution helps to improve processing accuracy and reduce processing errors caused by workpiece movement or sliding, thereby improving the quality of the final product;

[0027] 4. Stability and safety of the structure: The base plate, gas storage plate, pad and fixture carrier plate in the design are fastened and fixed by screws to form a stable overall structure. This fixing method not only increases the durability of the equipment, but also ensures safety and stability in high-speed or high-load operations;

[0028] 5. Simplified maintenance and operation: The design of the main exhaust port makes it easier to connect the exhaust equipment. Users can easily connect or replace the exhaust hose. In addition, the overall design takes into account the need for easy maintenance. The setting of the single-way air valve and the use of filter copper sheets reduce the difficulty of routine cleaning and maintenance;

[0029] 6. Wide applicability: The utility model is not only suitable for standard industrial processing environments, but can also be extended to a wider range of processing equipment. The versatility and adaptability of its design make it an ideal choice for a variety of production lines, and it has application prospects in the fields of semiconductors, automobile manufacturing and precision engineering.

[0030] In summary, the positioning device with adjustable vacuum area of ​​the utility model realizes efficient and precise processing of workpieces through its innovative design and functions, significantly improves production efficiency and product quality, and at the same time ensures operational flexibility and long-term stable operation of the equipment. These advantages make it a high-performance industrial equipment worthy of promotion. BRIEF DESCRIPTION OF THE DRAWINGS
