Technical Field

[0001] This utility model relates to the field of tooling and fixture technology for automated equipment, and in particular to a negative pressure fixing fixture for a film applicator. Background Technology

[0002] In automated production lines, film application is a common surface treatment process. To ensure accurate film placement and flatness, the parts to be applied need to be stably fixed. Existing film application machines typically use mechanical clamps for fixing parts during application. This method is prone to displacement and deformation of the parts, affecting the application effect; the fixing method between the fixture and the worktable mostly relies on screws or clips, which is inconvenient to operate and prone to loosening during long-term use, reducing the stability of the equipment; at the same time, existing vacuum adsorption fixtures are generally external vacuum sources, making the fixture system complex and inconvenient to operate. Therefore, we propose a negative pressure fixing fixture for film application machines that integrates a dual negative pressure system design and a highly efficient and compact vacuum generator. Utility Model Content

The vacuum generating device is installed inside the fixture body and connected to the air inlets of the first and second negative pressure systems respectively, used to provide a stable vacuum environment for the two negative pressure systems.

[0005] Preferably, the vacuum generating device is an independent dual-channel micro vacuum pump, used to control the vacuum pressure of the first negative pressure system and the second negative pressure system respectively.

Detailed Implementation

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "vertical", "horizontal", "inner", "outer", "front", "back", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figure 1 and Figure 3 As shown, this utility model proposes a negative pressure fixing fixture for a film applicator, comprising: a fixture body 1, a first negative pressure system 2, a second negative pressure system 3, and a vacuum generating device 4. The fixture body 1 is made of high-strength, lightweight material to ensure sufficient structural strength and portability. Multiple adsorption chambers 12 are precisely designed inside the fixture body 1, which respectively form the first negative pressure system 2 and the second negative pressure system 3. The adsorption chamber 12 of the first negative pressure system 2 is located in the top region of the fixture body 1 and is connected to a first adsorption surface 5 disposed on the surface of the fixture body 1. The first adsorption surface 5 is made of a high-adsorption-performance material, which can firmly adsorb the parts to be applicated, ensuring that the parts will not move or fall off during the applicator process. The adsorption chamber 12 is connected to the vacuum generating device 4 through an internal channel to form a stable negative pressure environment. The adsorption chamber 12 of the second negative pressure system 3 is located in the bottom region of the fixture body 1 and is connected to a second adsorption surface 6 disposed at the bottom of the fixture body 1. The second adsorption surface 6 is used to adsorb the fixture body 1 onto the worktable of the laminating machine to ensure the stability of the fixture during the laminating process.

[0021] Furthermore, the vacuum generating device 4 employs an independent dual-channel micro vacuum pump to control the vacuum pressure of the first negative pressure system 2 and the second negative pressure system 3 respectively. This design significantly reduces the size and installation complexity of the equipment, eliminates the need for an external vacuum source, and allows users to independently adjust the adsorption strength of the two systems to adapt to different sizes and weights of film-applied components and different working environments.

[0022] Furthermore, the fixture body 1 is provided with multiple air inlets 7 for supplying air to the vacuum generator 4. At the same time, a microporous filter 8 is provided at the air inlet 7, which can effectively prevent impurities from entering the vacuum generator, thereby protecting it from contamination and damage and improving the service life of the vacuum generator.

[0023] Furthermore, an elastic damping pad 9, made of rubber, is provided between the vacuum generating device 4 and the fixture body 1 to reduce vibration and noise transmission. In addition, multiple silencers 10 are provided on the fixture body 1 to further reduce the noise level during operation and improve the durability and user comfort of the fixture.

[0024] Furthermore, multiple vacuum pressure sensors 11 are provided on the main body 1 of the fixture. The vacuum pressure sensors 11 are connected to the first negative pressure system 2 and the second negative pressure system 3 respectively, so as to realize real-time monitoring of the vacuum degree of the two systems and ensure that the fixture maintains a stable adsorption effect during the film application process.

[0025] Furthermore, the negative pressure fixing fixture of the film applicator also includes a control module. The control module is electrically connected to the vacuum generator 4 and the vacuum pressure sensor 11. Through the control module, the user can automatically adjust the working parameters of the vacuum pump, such as vacuum degree and working time, according to the needs, and view the vacuum pressure data of the two systems in real time, so as to achieve precise control and improve the efficiency and accuracy of film application.

[0026] Working principle:

[0027] In use, the user first places the fixture body 1 onto the worktable of the laminating machine via the second suction surface 6 of the second negative pressure system 3. The negative pressure generated by the vacuum generator 4 firmly adheres the fixture to the worktable. Then, the part to be laminated is placed on the first suction surface 5 of the fixture body 1, and the vacuum generator 4 is activated. The vacuum generator 4 generates negative pressure through the first negative pressure system 2, firmly adhering the part to be laminated to the fixture. During the laminating process, the user can automatically adjust the vacuum pressure of the two systems as needed to ensure smooth operation. After laminating is complete, the user turns off the vacuum generator 4 and gently removes the part to be laminated and the fixture body 1.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.
