Description

Technical Field

[0001] The present invention relates to the technical field of vacuum degassing equipment, and particularly relates to a vacuum degassing machine. Background Art

[0002] Vacuum degassing machines are mainly used in fields such as electronics, chemicals, and materials to perform degassing treatment on materials such as colloids and liquids containing bubbles in a vacuum environment to improve the uniformity of the materials and product quality. Traditional vacuum degassing machines usually include a frame, a vacuum chamber, a vacuum pumping system, and a material placement device, and the bubbles in the material are expanded and escaped by pumping vacuum. With the improvement of the demand for automated production, higher requirements are put forward for the material loading and unloading efficiency, degassing effect, equipment stability, and multitasking processing ability of the degassing machine.

[0003] Deficiencies of the prior art: 1. Low degree of automation in material loading and unloading Traditional degassing machines mostly rely on manual placement or transfer of materials to be degassed, with low efficiency and prone to material position deviation or detachment due to manual operation, affecting the continuity and stability of the degassing process.

[0004] 2. Single structure of the material tray and insufficient fixing reliability Existing material trays are usually of a single-layer planar structure, with a single material placement method and a lack of effective fixing devices. During the degassing process, the materials may shift due to vibration or changes in vacuum pressure, resulting in uneven degassing or material spillage, affecting product quality.

[0005] 3. Insufficient degassing auxiliary functions Traditional degassing machines only rely on the vacuum environment for degassing and lack a vibration auxiliary mechanism (such as a vibration table). For materials with high viscosity or strong bubble adhesion, the degassing efficiency is low, and it is difficult to meet the processing requirements of complex materials.

[0006] 4. Poor equipment stability and operation convenience The opening and closing mechanism of the vacuum chamber of the existing equipment may lack a buffer design, with a large impact force during closing, affecting the service life and sealing performance of the equipment; at the same time, the bottom support structure of the equipment is fixedly non-adjustable, making it difficult to adapt to different ground environments, resulting in increased vibration during operation; in addition, there is a lack of a visual observation window, which is not convenient for real-time monitoring of the degassing process.

[0007] 5. Limited multitasking processing ability Traditional degassing machines usually only have a single vacuum chamber and a single material processing path, unable to process multiple batches of materials synchronously, making it difficult to improve production efficiency and difficult to meet the requirements of large-scale industrial production.

[0008] Therefore, there are deficiencies in the prior art and further improvements are needed. Summary of the Invention

[0009] In view of the problems existing in the prior art, the present invention provides a vacuum degassing machine.

[0010] To achieve the above object, the specific solution of the present invention is as follows: The present invention provides a vacuum degassing machine, comprising: A frame; A vacuum chamber provided on the frame; A vacuum pumping system communicated with the vacuum chamber; A material tray provided in the vacuum chamber for placing the material to be degassed; And a lifting drive mechanism for driving the vacuum chamber to move up and down to realize opening and closing.

[0011] Further, the vacuum degassing machine further comprises a robotic arm mechanism for transferring the material to be degassed to the material tray; The robotic arm mechanism includes a left-right moving component, an up-down moving component, a front-back moving component, a suction cup component and a clamping jaw; The left-right moving component is installed on the frame, the up-down moving component is installed on the left-right moving component, and the front-back moving component is installed on the up-down moving component; The suction cup component is installed on the front-back moving component. The suction cup component is provided with a suction cup array for adsorbing and transferring the material to be degassed. The suction cup component is further provided with a clamping jaw, and the clamping jaw clamps the material to be degassed from both sides to prevent it from falling off.

[0012] Further, the vacuum chamber includes an upper cover and a base; the upper cover is buckled on the base to achieve sealing.

[0013] Further, a vibrating table is further provided on the base, and the material tray is installed on the vibrating table.

[0014] Further, the lifting drive mechanism includes a driving cylinder; The base is installed on the frame, and the driving cylinder is installed on the lower side of the base; The front end of the piston rod of the driving cylinder is provided with a mounting plate, and four push-pull rods are provided on the mounting plate. The other ends of the push-pull rods are installed on the upper cover; The driving cylinder drives the mounting plate through pushing and pulling to drive the push-pull rods, and further moves the upper cover up and down. When the upper cover moves upward away from the base, the material tray installed on the base is exposed, facilitating the placement of the material to be degassed. When the upper cover moves downward and buckles on the base, vacuum degassing treatment is carried out.

[0015] Further, a buffer is further installed on the base. When the upper cover descends onto the base, the buffer is used for buffering.

[0016] Furthermore, the vacuum pumping system includes a vacuum pump, a vacuum pipe connected to the vacuum pump, and a vacuum valve and a vacuum pressure sensor arranged on the vacuum pipe. The vacuum pump is driven by a vacuum motor, and the vacuum pipe is connected to the top or side wall of the vacuum chamber.

[0017] Further, the material tray is a multi-layer structure, including a left bracket and a right bracket installed on a vibration table in the vacuum chamber; The left bracket and the right bracket are provided with supporting blocks, and the supporting blocks are provided with supporting plates; Place the material to be degassed on the support blocks on both sides or on the support plate.

[0018] Furthermore, the material tray is also provided with a pressing component; A pressing component is respectively provided on the left bracket and the right bracket; The pressing assembly comprises a push rod, a side plate and a slide rail; A slide rail is installed on the left bracket and the right bracket respectively, and the side plate is installed on the slide rail. The side plate is installed with a plurality of downward pressing claws, which are connected to the side plate through downward pressing springs, and the front ends of the downward pressing claws are suspended above the support plate; when the upper cover presses down the push rod, the side plate moves down along the slide rail, and the downward pressing claws press the support plate and the material to be degassed placed on the support plate under the action of the spring.

[0019] Furthermore, four adjustable support feet are provided at the bottom of the rack to ensure stable placement of the equipment; The upper cover of the vacuum chamber is also provided with an observation window for observing the internal conditions; The frame is provided with two vacuum chambers and two mechanical arm mechanisms for synchronously performing vacuum degassing work.

[0020] The technical solution of the present invention has the following beneficial effects: 1. Material transfer automation and stability improvement The patented robotic arm mechanism integrates left-right, up-down, front-back moving components and a suction cup-claw composite structure. The suction cup array absorbs the material and fixes it with the two side claws to accurately transfer the material to be degassed to the material tray. Compared with traditional manual operation, it significantly improves the efficiency of material loading and unloading, avoids position deviation or falling problems caused by manual operation, and ensures the continuity and stability of the degassed process. The pressing assembly strengthens the reliability of material fixation. The pressing assembly set on the material tray drives the side plate to move down along the slide rail through the upper cover pressing rod, so that the pressing claw presses the tray and the material under the action of the spring. This design can effectively prevent the material from shifting or spilling due to vibration or vacuum pressure changes during the degassing process, and is especially suitable for stable fixation of materials under complex working conditions. II. Optimization of Defoaming Efficiency and Processing Capacity The vibrating table integrated on the base assists in enhancing the defoaming effect. The combined action of the vibrating table and the vacuum environment accelerates the escape of bubbles in materials with high viscosity or strong bubble adhesion through vibration, compensating for the deficiency of traditional defoaming machines that rely solely on the vacuum environment, significantly improving defoaming efficiency and uniformity, and broadening the adaptability of the equipment to different types of materials. The multi-layer material tray improves space utilization. The material tray adopts a multi-layer structure (left bracket, right bracket, support block, tray), supporting the flexible placement of materials on the support blocks or trays, enabling the simultaneous processing of multiple batches or different specifications of materials, and significantly enhancing the space utilization of the vacuum chamber and the diversity of material processing compared to the single-layer structure. The dual vacuum chambers and the robotic arm enable synchronous production. The frame is equipped with two vacuum chambers and corresponding robotic arm mechanisms, supporting the synchronous defoaming treatment of multiple batches of materials, breaking through the production capacity limitation of traditional single-chamber single-machine, significantly improving the efficiency in large-scale production, and reducing the unit material processing cost. III. Improvement of Equipment Stability and Operation Convenience The buffer type lifting drive mechanism enhances sealing performance and lifespan. The lifting drive mechanism uses a driving cylinder in conjunction with a push-pull rod to drive the opening and closing of the upper cover. The buffer on the base can absorb the impact force when the upper cover closes, reducing damage to the sealing structure caused by mechanical vibration, extending the service life of the equipment, and ensuring the sealing reliability of the vacuum chamber. The adjustable support feet and the observation window enhance practicality. The adjustable support feet at the bottom of the frame adapt to different ground environments, ensuring the stable operation of the equipment through height adjustment, reducing interference to the defoaming process caused by vibration; the observation window on the upper cover supports real-time visual monitoring, facilitating operators to directly grasp the material state and defoaming process, improving operation convenience and the response speed to abnormal situations. IV. Advantages of System Control and Function Integration The vacuum pumping system is configured with a vacuum pressure sensor and a vacuum valve, which can accurately monitor and control the pressure in the vacuum chamber. Combined with the evacuation motor driving the vacuum pump to achieve efficient air extraction, ensuring the stable operation of the defoaming process under set parameters, and improving the process control accuracy and product quality consistency.

[0031] The material tray 4 is of a multi - layer structure, including a left support 21 and a right support 22 installed on the vibrating table 13 inside the vacuum chamber 2; The left support 21 and the right support 22 are provided with support blocks 23, and support plates 24 are arranged on the support blocks 23; The material to be degassed is placed on the support blocks 23 on both sides or on the support plates 24.

[0032] The material tray 4 is also provided with a downward - pressing component; One pressing component is respectively arranged on the left support 21 and the right support 22; The pressing component includes a push rod 25, a side plate 26, and a slide rail 27; One slide rail 27 is respectively installed on the left support 21 and the right support 22. The side plate 26 is installed on the slide rail 27. A number of pressing claws 28 are installed on the side plate 26. The pressing claws 28 are connected to the side plate 26 through pressing springs 29. The front end of the pressing claws 28 is suspended above the support plate 24.

[0033] Four adjustable support feet 30 are arranged at the bottom of the frame 1 to ensure the stable placement of the equipment; An observation window 31 for observing the internal situation is further arranged on the upper cover 11 of the vacuum chamber 2; Two vacuum chambers 2 and two robotic arm mechanisms 5 are arranged on the frame 1 for synchronously performing vacuum defoaming work.

[0034] Working principle: I. Material transfer and chamber preparation stage: 1. The robotic arm of the automated feeding robotic arm mechanism 5 is positioned at the storage position of the material to be defoamed through the left - right, up - down, and front - back moving components 8 (three - axis motion system). The suction cup array of the suction cup component 9 adsorbs the material, and at the same time, the clamping claws 10 on both sides clamp the material to prevent it from falling off. Subsequently, the robotic arm accurately transfers the material to the material tray 4 on the base 12 of the vacuum chamber 2, which is supported on the support block 23 or the support plate 24 (multi - layer structure), completing the feeding process. 2. The opening and closing control of the vacuum chamber 2: The driving cylinder 15 of the lifting drive mechanism 14 drives the mounting plate 16 through the piston rod, driving the four push rods 17 to move the upper cover 11 up and down: Open state: The piston rod of the cylinder contracts, and the upper cover 11 moves upward away from the base 12, exposing the material tray 4 for easy feeding by the robotic arm or manually; Closed state: The piston rod of the cylinder extends, and the upper cover 11 descends to buckle the base 12. The buffer 18 on the base 12 absorbs the closing impact force to ensure the sealing performance. II. Defoaming treatment stage 1. Vacuum environment construction: The vacuum pumping system 3 is started. The evacuation motor 20 drives the vacuum pump 19 to extract the air in the chamber through the vacuum pipeline (connected to the top / side wall of the chamber). The vacuum pressure sensor monitors the pressure value in real - time, and the vacuum valve adjusts the intake air volume until the set vacuum degree is reached, providing a low - pressure environment for defoaming. 2. Vibration - assisted defoaming: The vibrating table 13 on the base 12 is started synchronously to generate vibration, acting together with the vacuum pumping system: Under low pressure, the bubbles in the material expand, and vibration prompts the bubbles to escape by overcoming the surface tension. Especially for high-viscosity materials, it accelerates the separation of bubbles, improving the defoaming efficiency and uniformity. 3. When the upper cover 11 is closed with strengthened fixation of the material, the inner wall presses down the ejector rod 25 of the material tray 4, driving the side plate 26 to move downward along the slide rail 27, so that the downward pressing claw 28 (connected by a downward pressing spring 29) presses tightly against the support plate 24 and the material: The spring buffer design avoids rigid extrusion, ensuring that the material remains stable during vibration and pressure changes, preventing displacement or spillage. III. Multitask Synchronous Processing and Monitoring 1. The double-chamber parallel operation rack 1 integrates two independent vacuum chambers 2 and corresponding robotic arm mechanisms 5, which can simultaneously perform processes such as feeding, defoaming, and discharging, realizing synchronous processing of multiple batches of materials and significantly improving production capacity.

[0035] 2. The observation window 31 on the upper cover 11 for visualizing the operating state supports real-time observation of the material state and defoaming process. Operators can dynamically adjust parameters such as vacuum degree and vibration frequency by combining the data of the pressure sensor with visual monitoring. IV. Discharging and Equipment Adjustment After defoaming is completed and the discharging reaches the set defoaming time, the vacuum system 3 stops, the vacuum valve opens to release the chamber pressure, the upper cover 11 rises, and the robotic arm acts again to move the material away from the tray, completing the discharging cycle. Equipment stability guarantee: The adjustable support feet 30 at the bottom of the rack 1 can adjust the height according to the ground flatness, ensuring the equipment runs smoothly and reducing the interference of vibration on the defoaming accuracy. Core coordination mechanism Vacuum-vibration combined action: The vacuum environment reduces the surface tension of the bubbles, and the vibration table 13 destroys the attachment state of the bubbles. The combination of the two achieves efficient defoaming; Automated material handling: The robotic arm and the downward pressing component cooperate to achieve stable control of the entire process of "adsorption - clamping - positioning - pressing" of the material; Modular double-chamber design: Driven by an independent control system, the double chambers and the robotic arm support the parallel operation of the "feeding - defoaming - discharging" process, maximizing the equipment utilization rate.
