Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a negative pressure airlock clamping device. Background Technology

[0002] The relevant technology indicates that during the production and processing of automotive lenses, the surface needs to be polished. Clamping fixtures are required to position the lenses during polishing and during subsequent transport.

[0003] Most existing clamping fixtures are simple rigid clamps, which can easily damage lenses when clamping them. There is also a type of pneumatic clamp that uses a suction cup to continue to grip the lens. However, the pneumatic clamps currently used in lens processing do not have adjustability when gripping lenses. Therefore, they cannot adjust the gripping position to ensure accurate and stable gripping for different lenses. Furthermore, in order to accurately polish the sides during the polishing process, the lens needs to be slightly tilted for positioning. Existing fixtures do not have the function of adjusting for slight tilting, resulting in poor adaptability. Utility Model Content

[0020] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] Reference below Figure 1 Description of a negative pressure airlock clamping device 100 according to an embodiment of the present utility model.

[0022] like Figure 1 As shown, the negative pressure airlock clamping device 100 according to an embodiment of the present utility model includes: a cabinet 1, an adjustment component 2, and an adsorption component 3.

[0023] Specifically, the negative pressure airlock clamping device 100 is used to transfer automotive lenses. The adjusting component 2 is located in the cabinet 1 and includes an adjusting member 21, which is movably disposed within the cabinet 1. An adsorption member 3 is located at one end of the adjusting member 21 and can rotate relative to the adjusting member 21. The adsorption member 3 is used to adsorb automotive lenses. Thus, automotive lenses are stably adsorbed with good adaptability, and the rotation of the adsorption member 3 relative to the adjusting member 21 allows for tilting of the automotive lenses.

[0024] Understandably, cabinet 1 provides support for other components. Adjustment component 21 moves within cabinet 1, either along the length, width, or height of cabinet 1. This allows adsorption component 3 to reach different positions to accommodate car mirrors at different placement positions or angles. Adsorption component 3 is installed at one end of adjustment component 21 and can rotate relative to adjustment component 21, enabling adsorption component 3 to effectively adsorb car mirrors. By adjusting the height of adjustment component 21, the car mirror can be tilted. Utilizing the principle of negative pressure (i.e., generating attraction by reducing pressure in a localized area), adsorption component 3 can safely and reliably fix lightweight but fragile items such as car mirrors without causing damage.

[0025] The working process of the negative pressure airlock clamping device 100 is described as follows: The negative pressure airlock clamping device 100 is installed in the polishing area or on the transfer equipment. According to the size of the car lens, the adjustment component 2 is adjusted so that the adjustment component 21 is in an appropriate position, thereby realizing the position adjustment of the adsorption component 3. This allows the adsorption component 3 to be accurately positioned at the position where the car lens needs to be adsorbed. Then, the car lens is placed on top of the adsorption component 3, and the negative pressure of the adsorption component 3 is used for adsorption, thereby making the adsorption of the car lens accurate and stable, ensuring the safety of the car lens. At the same time, the negative pressure airlock clamping device 100 has strong adaptability.

[0026] According to the negative pressure airlock clamping device 100 of this utility model embodiment, by setting the adjustment component 2, the position and height of the adsorption component 3 are adjustable. For different specifications of car lenses, the accuracy and stability of adsorption positioning are improved. The adsorption component 3 can rotate relative to the adjustment component 21, and the angle of the adsorption component 3 is adjustable, realizing the tilt positioning of the car lens, ensuring the fit between the adsorption component 3 and the car lens, and improving the grinding efficiency of the side of the car lens.

[0027] In some embodiments of this utility model, the cabinet 1 has a guide groove, a guide tube is provided in the guide groove, the guide tube is movably disposed in the guide groove, and a guide channel perpendicular to the guide groove is formed in the guide tube. The adjusting member 21 is movably disposed in the guide tube along the axis of the guide channel. Specifically, the guide groove can restrict the movement of the guide tube in a predetermined direction, the guide channel can restrict the movement of the adjusting member 21 in the guide tube along its axial direction, and the adjusting member 21 can move in the predetermined direction of the guide groove through the guide tube. It can be understood that since the adjusting member 21 can move in two mutually perpendicular directions (one is the direction of movement provided by the guide groove, and the other is the direction of movement provided by the guide channel), the adjusting component 2 has a high degree of spatial freedom. By combining the adjustment capabilities in multiple directions, the negative pressure airlock clamping device 100 can adapt to various working environments and task requirements very flexibly, while ensuring stability and safety during operation.

[0028] In some embodiments of this utility model, a buffer is provided inside the guide tube. The buffer is located at one end of the adjusting member 21 within the guide groove, and the peripheral wall of the buffer is in contact with the inner peripheral wall of the guide tube. That is, the buffer is connected to one end of the adjusting member 21. When the adjusting member 21 stops moving, the buffer can reduce the moving speed of the adjusting member 21, reduce impact and wear, and reduce noise.

[0029] In some embodiments of the present invention, Figure 1 As shown, the adjustment assembly 2 also includes a ball joint 22, which is located between the adjustment member 21 and the adsorption member 3. It is understood that the ball joint 22 is a mechanical connector that allows multi-directional rotation between the two connecting parts, improving the flexibility of angle adjustment between the adjustment member 21 and the adsorption member 3. This facilitates adaptation to automotive lenses of different shapes, positions, and angles, ensuring that the adsorption member 3 can adsorb the lens with the optimal contact surface, enhancing the adsorption effect and reducing the potential risk of damage caused by improper angles.

[0030] In some embodiments of this utility model, the adjusting component 2 includes multiple components, and the adsorption component 3 includes multiple components, with each adjusting component 2 and adsorption component 3 arranged in a one-to-one correspondence. That is, each adsorption component 3 is provided with a corresponding adjusting component 2 to control its position and angle, which improves the flexibility and adaptability of the adjusting component 2 and ensures that each automotive lens can be accurately and safely adsorbed and transported.

[0031] In some embodiments of this utility model, the negative pressure airlock clamping device 100 further includes a negative pressure pump. A receiving cavity is formed within the cabinet 1, and the negative pressure pump is located within the receiving cavity. The negative pressure pump is connected to each adsorption element 3 via a negative pressure pipe 4 to create negative pressure at the position of the adsorption element 3 to adsorb the car lens. That is, when the negative pressure pump starts working, it draws air from the vicinity of the adsorption element 3 through the negative pressure pipe 4, reducing the pressure in that area. As the pressure near the adsorption element 3 decreases, the surrounding atmospheric pressure pushes the car lens towards the adsorption element 3, thus firmly adsorbing it. Negative pressure adsorption is a non-contact gripping method that reduces the risk of physical damage to fragile items such as car lenses. Through the design of the adjusting component 2 and the ball hinge 22, the adsorption element 3 can be flexibly adjusted to adapt to lenses of different shapes and sizes. Negative pressure adsorption provides a uniform and stable gripping force, ensuring the safety of the lens even when encountering slight vibrations during handling. Therefore, it not only improves work efficiency but also greatly enhances the safety and reliability during handling.

[0032] Furthermore, the negative pressure airlock clamping device 100 also includes a mounting assembly. The mounting assembly is located within the receiving cavity, and the negative pressure pump is fixed to the mounting assembly. The mounting assembly ensures that the negative pressure pump can be securely installed within the receiving cavity of the cabinet 1, thereby ensuring the stable operation of the entire system. The mounting assembly includes a mounting block and a mounting plate. The mounting block is located on the mounting plate, and the negative pressure pump is located on the mounting block. The mounting plate has mounting holes that penetrate the mounting plate in the thickness direction. It is understood that the combination of the mounting block and the mounting plate provides a stable and reliable mounting platform for the negative pressure pump and other components, supporting and fixing the negative pressure pump. This effectively reduces the impact of vibrations generated during equipment operation on other components. Furthermore, when maintenance or replacement of the negative pressure pump is required, the negative pressure pump and its mounting block can be easily removed simply by disassembling the relevant fasteners, without completely removing the mounting plate. This not only improves the overall stability and reliability of the negative pressure airlock clamping device 100 but also simplifies the assembly and maintenance process. Through a reasonable layout and fixing method, the mounting assembly ensures that the negative pressure pump maintains good performance during long-term operation, while also facilitating daily inspection and maintenance.

[0033] In some embodiments of this utility model, the adjusting component 2 further includes: a first driving member 23 and a second driving member. The first driving member 23 is connected to the guide tube to drive the guide tube to move, and the second driving member is connected to the adjusting member 21 to drive the adjusting member 21 to move relative to the guide tube. It is understood that the first driving member 23 and the second driving member can be linear (e.g., via an electric push rod or a pneumatic cylinder) or rotary (e.g., via a lead screw transmission system), thereby realizing the movement of the adjusting member 21 in space.

[0034] Specifically, firstly, the position of the guide tube is adjusted by the first driving component 23 (thereby adjusting the position of the adjusting component 21) so that the adsorption component 3 is roughly aligned with the car lens to be adsorbed; then, the height of each adjusting component 21 is adjusted using the second driving component to ensure that each adsorption component 3 can accurately contact the lens surface; when all adsorption components 3 are correctly aligned, the negative pressure pump is started to form a negative pressure at the adsorption component 3, thereby firmly adsorbing the lens; after adsorption is completed, the height of some adjusting components 21 can be changed by the second driving component to achieve the required angle; after the transfer or polishing work is completed, the operation of the negative pressure pump is stopped or positive pressure is introduced to release the adsorption force, thereby safely placing the lens down, which helps to improve production efficiency and product quality.

[0035] In some embodiments of this utility model, a base 11 is provided on the lower side of the cabinet 1, and the base 11 is used to support the cabinet 1. This improves the stability and safety of the entire device, ensuring that the device is placed firmly on the working surface. To prevent the base 11 from sliding on the smooth ground, an anti-slip pad or rubber foot pad can be installed on the bottom of the base 11 to increase friction.
