Description

Technical Field

[0001] This invention relates to the field of clamping device technology, specifically to a clamping device that reduces damage and facilitates the installation of lift pins. Background Technology

[0002] In modern manufacturing, the design and function of fixtures have become key factors in improving production efficiency and product quality. Fixtures are commonly used in machining to fix, support, and position raw materials or workpieces, ensuring machining accuracy and operational safety. With the rapid development of automation and precision engineering, the demand for fixtures is constantly increasing, especially on high-precision and high-efficiency production lines, where the role of fixtures becomes particularly important because they directly affect the continuity of production and the accuracy of machining.

[0003] Currently, traditional fixture devices focus on basic fixing and positioning functions, typically including simple mechanical structures such as manually adjustable screws and fixing plates. Especially in ejector fixture devices, ejectors serve as the primary medium for wafer transfer interaction with robotic arms within the process cavity.

[0004] Regarding the aforementioned technologies, firstly, traditional ejector clamps often lack the function of adjusting the angle of a single or multiple ejector pins and adapting to ejector pins of different sizes, thus failing to quickly adapt to the changing processing needs on the production line. Secondly, they cannot effectively prevent mechanical damage, making the ejector pins prone to breakage. At the same time, the heat and dust generated during the process are not effectively managed, which may lead to workpiece quality problems and equipment failures. Therefore, those skilled in the art have provided a clamping device that reduces damage and facilitates the installation of lift pins to solve the problems mentioned in the background. Summary of the Invention

[0005] The purpose of this invention is to provide a clamping device that reduces damage and facilitates the installation of Lift Pins, thereby solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] By adopting the above technical solution, the fixture table serves as the foundation and is securely connected to the lifting cylinder, providing a stable support platform. The lifting cylinder, in conjunction with the rotating motor, achieves precise control of vertical and rotational movements. This transmission connection ensures the continuity and stability of operation. The rotating motor is also connected to the support ring assembly, which is rotatably connected to the angle assembly, allowing the equipment to adjust the workpiece angle during processing.

[0009] Furthermore, the support ring assembly includes a ring body, a first elastic element, a first hydraulic cylinder, a clamping block, and a balance plate. The ring body and the first elastic element are fastened together, the first elastic element and the balance plate are fastened together, the ring body is provided with a damping groove, the balance plate and the damping groove are slidably connected, the damping groove is triangular in shape, the balance plate is triangular in shape, there are three first elastic elements, the three first elastic elements are located at the three corners of the triangular shape of the balance plate, the first elastic elements and the damping groove are fastened together, the rotating motor and the balance plate are driven together, the first hydraulic cylinder and the ring body are fastened together, the first hydraulic cylinder and the clamping block are driven together, the angle assembly and the clamping block are rotatably connected, and the ring body is grounded.

[0010] By adopting the above technical solution, the ring body, as the main structure, is connected to three first elastic elements through fastening connections. These elastic elements are further fastened to the balance plate, forming a robust yet flexible support system. The shock-absorbing grooves on the ring body cooperate with the triangular design of the balance plate, allowing the balance plate to slide within the shock-absorbing grooves, thereby providing effective shock absorption and maintaining the stability of the equipment during operation. Each first elastic element is located at a corner of the balance plate and is fastened to the shock-absorbing groove, enhancing the overall structure's shock resistance and adjustment capabilities. The first hydraulic cylinder is fastened to the ring body and driven by the clamping block, providing power output. The drive connection between the rotating motor and the balance plate ensures that the balance plate can be rotated and adjusted according to processing needs. The rotational connection between the angle component and the clamping block allows the clamping block to be precisely positioned at different angles, optimizing the processing effect. The grounding treatment of the ring body ensures the electrical safety and stability of the equipment during operation. With this configuration, the clamping device can effectively reduce vibration and impact caused by processing while ensuring high precision and high stability, extending the service life of the equipment, improving processing quality, and ensuring the efficiency and safety of the operation process.

[0011] Furthermore, the angle assembly includes an angle block, an angle motor, a first transmission rod, a connecting module, and a rotating module. There are three angle blocks, a first hydraulic cylinder, and a clamping block. Each angle block and clamping block are rotatably connected. The angle motor and a clamping block are fastened together. The angle motor and the first transmission rod are driven together. The first transmission rod and the connecting module are driven together. The rotating module and the angle block are fastened together. The mounting assembly and the rotating module are fastened together. A first electromagnetic block is provided on the clamping block. The first electromagnetic block and the clamping block are fastened together. The first transmission rod is located inside the clamping block. The first transmission rod is located inside the angle block and passes through the angle block and the clamping block.

[0012] When the angle block rotates: the rotating module and the first transmission rod clamp and abut together, and the first transmission rod and the rotating module are connected by transmission.

[0013] When the angle block does not rotate: the first electromagnetic block and the rotating module are magnetically attracted to each other.

[0014] By adopting the above technical solution, each angle block and clamping block are rotatably connected, allowing the clamping block to be adjusted in multiple directions to adapt to different processing angles or insertion angle requirements. The angle motor is directly and securely connected to one of the clamping blocks, and transmits power to the connecting module through the first transmission rod. This design makes angle adjustment more precise and rapid. The first transmission rod passes through the inside of the clamping block and the angle block, ensuring direct and effective transmission of the transmission force. At the same time, the rotating module is securely connected to the angle block and to the mounting assembly, enhancing the stability of the overall structure and the reliability of operation. The first electromagnetic block is mounted on the clamping block and securely connected to it, providing a magnetic connection point for connecting the rotating module with magnetic force when needed. The magnetic connection between the modules provides a quick switching and adjustment method, increasing operational flexibility and speed. When the rotating module and the first drive rod are clamped together, a transmission connection is formed between them, allowing the rotating module to directly drive the first drive rod to rotate, thereby adjusting the position of the angle block and the clamping block. When not in contact, the magnetic connection between the first electromagnetic block and the rotating module ensures temporary fixation between the components until the next power transmission is required. With this configuration, the clamping device can achieve operational precision and repeatability, effectively supporting complex machining tasks. This angle component design not only improves mechanical efficiency but also optimizes the workflow, ensuring high efficiency and high-quality output in the production process.

[0017] In its normal state, the second elastic element is driven by magnetic attraction between the first electromagnetic block and the first magnetic block.

[0018] By adopting the above technical solution, the rotating shell serves as the main frame, firmly connected to the first magnetic block and the angle block to ensure the stability of the overall structure. The second electromagnetic block is fixed on the rotating shell and connected to the second elastic element. This configuration allows the second electromagnetic block to adjust its position through the extension and retraction of the elastic element. The sliding connection between the clamping abutment block and the rotating shell allows it to move linearly inside the rotating shell, while the extension and retraction of the second elastic element drives the formation or disconnection of the magnetic connection between the second electromagnetic block and the clamping abutment block. When the second elastic element is in the extended state, the second electromagnetic block is magnetically connected to the clamping abutment block. At this time, the clamping abutment block clamps and abuts against the first transmission rod, forming a transmission connection, thereby driving the clamping block to rotate through the rotating shell. When the second elastic element is in the normal state, the magnetic connection between the first electromagnetic block and the first magnetic block maintains the fixed state between the components, reduces mechanical wear, and enhances the service life and stability of the equipment. Through this design, the rotating module not only ensures operational flexibility and response speed but also improves processing accuracy and reliability.

[0019] Furthermore, the connecting module includes hinge rods, a first hinge block, a second hinge block, a third hinge block, and a second transmission rod.

Each group's second transmission rod passes through the angle block and the clamping block.

[0020] By adopting the above technical solution, each group contains four hinge rods. These hinge rods act as bridges in power transmission and position adjustment, connecting different hinge blocks. The first hinge block is connected to two hinge rods, which in turn connect to the second hinge block, forming a robust support and power transmission path. The third hinge block of each group is rotatably connected to the clamping block via a second transmission rod, achieving precise position adjustment and stable power output. This design allows the second transmission rod to pass through the angle block and the clamping block, ensuring the continuity and accuracy of transmission throughout the entire equipment operation. The setting of the second transmission rod also allows the two groups of hinge systems to work together. The second transmission rod of one group is connected to the first hinge block of the other group. This layout optimizes the force distribution and transmission efficiency. The connecting module improves the operational flexibility and mechanical stability of the clamping device. It enables the equipment to perform precise adjustments and stable operation in multiple directions, especially when handling machining tasks that require positioning and sustained stability, ensuring machining accuracy and equipment reliability. This not only improves production efficiency but also reduces maintenance costs and operational complexity.

[0021] Furthermore, the mounting assembly includes a ball-head plunger, a third elastic element, a mounting post, a lifting post, a cooling clamping module, a horizontal hydraulic cylinder, an adjusting nut, and a connecting bolt.

The third elastic element is also securely connected to the lifting column, forming a stable vertical support system. The snap-fit ​​design between the ball-head plunger and the ejector pin allows for quick installation or replacement of the ejector pin, while the snap-fit ​​groove design ensures the stability of the ejector pin during processing. The sliding connection between the mounting column and the lifting column allows for adjustment of the lifting column's height to accommodate workpieces of different lengths. The secure connection and transmission between the horizontal hydraulic cylinder and the mounting column provide precise vertical movement capability.

This airflow is guided through the spiral grooves of the inner spiral block to optimize the airflow path and ensure a more uniform and effective purging effect. The filter screen is securely connected to the air control module to capture and filter dust generated during the purging process, preventing these impurities from falling back onto the workpiece or spreading into the working environment. The recovery shell is also securely connected to the mounting column to collect the filtered dust for subsequent processing. Continuous processing and recycling are achieved through a wind control module securely connected to the lifting column, which adjusts and controls the airflow intensity generated by the fan to adapt to different operational needs and working conditions. This allows the purging assembly to remove dust from the ejector pin surface, keeping the workpiece and equipment clean and improving machining accuracy and workpiece quality. In addition, by optimizing the airflow path and filtration system, the purging assembly also helps to improve the safety and hygiene of the overall working environment, providing operators with a healthier and cleaner working space.

[0026] By adopting the above technical solution, the sliding connection between the air control plate and the air frame allows the air control plate to move on the air frame to adjust the airflow size, thereby more accurately controlling the airflow to blow on the workpiece. The air control motor is fixedly connected to the air frame and provides the necessary power to drive the movement of the air control plate, realizing rapid adjustment of the airflow. The air frame is designed with an air control port and a rotating slot. The air control port is connected to the mounting column through the rotating slot to ensure that the airflow generated by the fan can smoothly enter the working area through the air control module. This design allows airflow to be precisely guided and adjusted by the air control plate before reaching the work area, ensuring that the airflow reaches the target location at the most suitable speed and direction, improving cleaning efficiency. The filter screen is securely connected to the air control plate, filtering particulate matter in the air and preventing these particles from returning to the work area with the airflow, maintaining environmental cleanliness and precise workpiece processing quality. This configuration not only improves purging efficiency but also reduces potential impacts on workers and the environment by precisely controlling the direction and intensity of airflow, increasing operational safety and environmental friendliness. It can maintain high efficiency and accuracy while ensuring a clean working environment and operational safety, thus improving overall work performance and efficiency.

[0027] Furthermore, the cooling clamping module includes a first telescopic hose, a second telescopic hose, a clamping membrane, a cooling tank, a liquid pump, and an iris assembly.

The first telescopic hose is directly connected to the cooling tank, responsible for transporting coolant from the cooling tank to the lifting column, while the second telescopic hose is connected to the liquid pump, responsible for transporting coolant back to the cooling tank from the liquid pump, forming a closed-loop cooling system. The air outlet slot on the mounting column is connected to the spiral groove and to the ventilation holes on the mounting plate. These ventilation holes are in turn connected to the air control vents, allowing cooling air to flow freely inside the equipment, enhancing the cooling effect. The liquid pump is tightly connected to the iris assembly. The iris assembly, with its fixed connection, regulates the flow and pressure of the liquid pump, ensuring uniform distribution of coolant within the system. The clamping membrane is securely connected to the lifting column, providing isolation and protection. Furthermore, the iris assembly controls the extension of the clamping membrane to hold the ejector pin, preventing direct contact between liquid and electrical components or sensitive areas.

When not in contact, the magnetic connection between the first electromagnetic block and the rotating module ensures temporary fixation between the components. The rotating shell serves as the main frame, ensuring the stability of the overall structure. The second electromagnetic block is connected to the second elastic element, allowing for position adjustment. When the second elastic element extends, it forms a magnetic connection with the clamping block, thereby driving the clamping block to rotate through the rotating shell to meet the needs of different processing angles.
