Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a four-station material handling fixture for precise positioning. Background Technology
[0002] In the field of mold technology, especially in the automated loading and unloading process of small and medium-sized products, the problem of minute positional deviations caused by product diversity and tolerances is often encountered. These deviations make it difficult for traditional pick-up structures to accurately act on the product center, thus affecting production efficiency and finished product quality. Traditional pick-up jigs often lack the ability to reposition and adjust, and cannot effectively meet the precise pick-up and placement requirements of products of different sizes and shapes, leading to positional mismatches in subsequent processes, increasing the difficulty and cost of processing.

[0030] This utility model provides a four-station material handling fixture for precise positioning. By combining a second-direction motion positioning mechanism with a first-direction motion material handling component and a gripper assembly, it achieves precise positioning of the product in three-dimensional space. Even with slight positional deviations, the grippers can perform secondary positioning adjustments, ensuring the suction nozzle accurately aligns with the product's center for pick-up, thus improving the accuracy and stability of material handling. The gripper assembly, driven by a gripper drive, moves the first and second grippers closer together or further apart, accommodating products of various sizes and shapes. This allows the fixture to be applied to a wider range of product lines, reducing the cost and time of fixture changes and improving the flexibility and efficiency of the production line. Example
[0031] This utility model embodiment provides a four-station material handling fixture for precise positioning, such as... Figures 1 to 4 As shown, the device includes a material handling assembly 10, which includes a suction nozzle 110 and a material handling drive 120. The material handling drive 120 is connected to the suction nozzle 110 and is used to drive the suction nozzle 110 to move in a first direction. A positioning mechanism 20 includes a gripper assembly 210 and a positioning drive 220. The positioning drive 220 is connected to the gripper assembly 210 and is used to drive the gripper assembly 210 to move in a second direction. The gripper assembly 210 includes a first gripper 2110, a second gripper 2120, and a gripper drive 2130. The gripper drive 2130 is connected to both the first gripper 2110 and the second gripper 2120 and is used to drive the first gripper 2110 and the second gripper 2120 to move closer to or further away from each other. A positioning space exists between the first gripper 2110 and the second gripper 2120, and the center point of the positioning space can coincide with the center point of the suction nozzle 110.
[0032] The first direction can generally be understood as the extension direction of the nozzle 110 or the suction direction. More specifically, the first direction and the second direction are perpendicular to each other. In this way, the positioning drive 220 drives the gripper assembly 210 to move closer to the nozzle 110, and then the first gripper 2110 and the second gripper 2120 are respectively located on both sides of the nozzle 110. The gripper drive 2130 drives the first gripper 2110 and the second gripper 2120 to move closer to each other, adjusting the position of the product picked up by the nozzle 110 so that the nozzle 110 can pick up the product at the center.
[0033] The fixture has a compact structure, and the connections and drive methods between its components are simple and clear, making it easy to integrate and deploy on existing automated production lines. This reduces the difficulty of installation and maintenance, and helps to keep the production line clean and efficient. By integrating the material handling drive 120 and the positioning drive 220, the fixture automates the material handling process, reduces manual intervention, and improves production efficiency.
[0034] More specifically, the movement directions of the first gripper 2110 and the second gripper 2120 are perpendicular to the first direction and the second direction, respectively.
[0035] Because the movement direction of the grippers is perpendicular to the movement direction of the material handling assembly 10, this orthogonal layout allows for precise, blind-angle-free adjustment of the product in three-dimensional space. This orthogonal layout not only improves positioning accuracy but also enhances the stability and reliability of the entire material handling process.
[0036] One possible workflow of this application is as follows: the material picking drive 120 drives the suction nozzle 110 to extend downwards, and after the material picking is completed, it drives the suction nozzle 110 to rise. Then, the positioning drive 220 drives the gripper assembly 210 to extend forward towards the position of the suction nozzle 110. When the center point of the positioning space between the first gripper 2110 and the second gripper 2120 coincides with the center point of the suction nozzle 110, the positioning drive 220 stops moving. The gripper drive 2130 drives the first gripper 2110 and the second gripper 2120 to move closer to each other to adjust the position of the product picked up by the suction nozzle 110, so that the suction nozzle 110 can ensure that it picks up the product in the center.
[0037] In this way, the entire material handling and positioning process can be highly automated, requiring only minimal manual monitoring or pre-programmed operation for continuous operation. The coordinated work of the material handling drive 120 and the positioning drive 220 enables the suction nozzle 110 and the gripper assembly 210 to move precisely according to a preset trajectory and sequence, greatly simplifying the operation process and improving work efficiency. Through the precise cooperation between the suction nozzle 110 and the gripper assembly 210, even with products exhibiting slight positional deviations, the suction nozzle 110 can accurately pick up the product's center. After the center point of the gripper assembly 210 coincides with the center point of the suction nozzle 110 in the positioning space, precise adjustment of the product position is achieved by fine-tuning the gripper spacing, thereby effectively improving the product's pass rate and consistency.
[0038] like Figure 3 and Figure 4 As shown, the first gripper 2110 and the second gripper 2120 are symmetrically arranged. Specifically, one end of the first gripper 2110 may have a protrusion 21110. More specifically, one side of the protrusion 21110 may have a concave portion 21120. The concave portion 21120 may be arc-shaped.
[0039] In this way, the symmetrically arranged gripper assemblies 210 can evenly distribute the clamping force, ensuring balanced force on the product during clamping and avoiding product damage or positioning deviation caused by uneven force. This is suitable for products with regular shapes and flat surfaces, providing a more stable clamping effect. The protrusion 21110 allows the gripper assembly 210 to perform secondary positioning operations more quickly during clamping. The concave portion 21120, especially the arc-shaped concave portion 21120, allows the grippers to adjust their position more flexibly during clamping to adapt to products of different sizes and shapes. The arc-shaped concave portion 21120 can better conform to the product contour, reduce gaps during clamping, and improve clamping accuracy and stability.
[0040] like Figure 1 As shown, specifically, the four-station material handling fixture for precise positioning provided in this embodiment of the invention also includes a connecting plate 30, on which four material handling components 10 are sequentially arranged. More specifically, it also includes a retaining ring 40, which is fixedly connected to the connecting plate 30. In this way, by integrating multiple material handling components 10 through the connecting plate 30, multiple materials can be picked up and placed at once. The retaining ring 40 is fixedly connected to the connecting plate 30, so that a robotic arm or robot can connect to the retaining ring 40, thereby driving the connecting plate 30 to perform displacement, rotation, and other movements to achieve material picking and placing.
[0041] More specifically, both the material handling drive 120 and the positioning drive 220 are cylinders.
[0042] Understandably, by sequentially arranging four material handling components 10 on the connecting plate 30, the function of handling multiple materials in a single operation is achieved. This improves production efficiency, especially on production lines requiring a large number of repetitive handling operations, significantly shortening the production cycle. The fixed connection design between the clamping ring 40 and the connecting plate 30 provides a convenient way to connect the fixture to the robotic arm or robot. Through the clamping ring 40, the fixture can be firmly mounted on the robotic arm, realizing various movements such as displacement and rotation, thereby meeting the diverse handling needs on complex production lines. This design not only improves the versatility of the fixture but also enhances the flexibility and automation of the production line. Using cylinders as the material handling drive component 120 and the positioning drive component 220 ensures the stability and reliability of the fixture during the material handling and positioning process. Cylinders have advantages such as simple structure, rapid action, and easy control, and can meet the requirements of high-speed and high-precision material handling. At the same time, the maintenance cost of cylinders is relatively low, which helps to reduce the overall production cost. Of course, in addition to cylinders, the drive components of this application can also be selected from existing technologies that can achieve the same or similar functions.
[0043] The integrated design of components such as the connecting plate 30, the retaining ring 40, and the cylinder makes the overall structure of the fixture compact, easy to install and maintain. This not only saves production space but also improves the fixture's durability and service life. Through this structure, the fixture can achieve fast and accurate material handling and positioning operations, reducing manual intervention and errors, thereby improving production efficiency and product quality. This is of great significance for modern manufacturing industries that pursue high quality and high efficiency.
[0044] Compared with existing technologies, this utility model provides a four-station material handling fixture for precise positioning. Through a second-direction motion positioning mechanism 20 combined with a first-direction motion material handling component 10 and a gripper assembly 210, precise positioning of the product in three-dimensional space is achieved. Even with slight positional deviations in the product, secondary positioning adjustments can be made via the grippers, ensuring the suction nozzle 110 accurately aligns with the product center for picking up material, thus improving the accuracy and stability of material handling. The gripper assembly 210, driven by a gripper drive component 2130, moves the first gripper 2110 and the second gripper 2120 closer or further apart, accommodating products of various sizes and shapes. This allows the fixture to be applied to a wider range of product lines, reducing the cost and time of fixture replacement and improving the flexibility and efficiency of the production line.
[0045] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model.
