[0031] A middle frame positioning mechanism provided by the present utility model realizes the bilateral pushing and positioning of the placed article through the relative structural layout of the first positioning member and the first limiting member, and the second positioning member and the second limiting member. This mechanism of simultaneous bilateral action effectively avoids the deviation that may be caused by unilateral positioning, thereby significantly improving the positioning accuracy and ensuring the accuracy and consistency of product assembly. The positioning mechanism can be adapted to mobile phone middle frames and other similar products with different outer shape size ratios. By adjusting the positions or sizes of the limiting component and the positioning component, various specifications of products can be easily adapted, greatly enhancing the flexibility and efficiency of the production line and reducing the mold manufacturing cost and replacement frequency. Embodiment
[0032] An embodiment of the present utility model provides a middle frame positioning mechanism, as Figures 1 to 3 shown, which includes a fixture main body 10. The fixture main body 10 includes a substrate 110 and a positioning plate 120. The positioning plate 120 is arranged on the substrate 110. The positioning plate 120 includes a placement area 1210 for placing the middle frame; a limiting component 20, the limiting component 20 includes a first limiting member 210 and a second limiting member 220, and both the first limiting member 210 and the second limiting member 220 are arranged on the positioning plate 120; a positioning component 30, the positioning component 30 includes a first positioning member 310 and a second positioning member 320, the first positioning member 310 is arranged opposite to the first limiting member 210, and the second positioning member 320 is arranged opposite to the second limiting member 220; an adsorption component 40, the adsorption component 40 is arranged in the placement area 1210.
[0033] As Figure 1 shown, more specifically, the substrate 110 and the positioning plate 120 are inclined. In this way, the inclined substrate 110 and the positioning plate 120 can better guide the middle frame or similar products to be placed at a certain angle. This preset angle positioning helps to reduce the positioning error caused by non-parallel or offset placement of the product. The inclined surface can provide a clearer visual and physical guidance, enabling the operator to more intuitively judge the placement position and angle of the product when placing the product, thereby further improving the positioning accuracy. The combination of the inclined substrate 110 and the positioning plate 120 can form a certain support structure, making the product placed on it more stable and not easily displaced due to external force or vibration.
[0034] It can be understood that after placing the middle frame or other identical or similar products to be positioned on the placement area 1210 of the positioning plate 120, the first limiting member 210 and / or the second limiting member 220 play a role in supporting the placed article, preventing the product from falling. Then, the first positioning member 310 and the second positioning member 320 move towards the placed article, making the placed article closely adhere to the first limiting member 210 and the second limiting member 220. Finally, the adsorption assembly 40 adsorbs the adsorption assembly 40 to ensure that the adsorption assembly 40 is closely adhered to the positioning plate 120, and finally the positioning is completed. Such a middle frame positioning mechanism avoids the situation of incomplete pressing through pushing from both sides, improves the positioning accuracy and stability, has strong versatility, and can be compatible with mobile phone middle frames and other similar products with different outer dimensions.
[0035] Among them, the coordinated action of the limiting assembly 20 and the positioning assembly 30 not only ensures the stability of the product during the positioning process, but also makes the product closely fit the positioning plate 120 through the pushing action, reducing the displacement caused by vibration or external interference, and improving the overall structural stability. Both automated or manual operations are simple and fast. Just place the product on the placement area 1210, and the positioning assembly 30 is automatically or manually activated for pushing and positioning. Finally, it is fixed by the adsorption assembly 40. The whole process is smooth and efficient, reducing the operation difficulty and labor cost. The high-precision positioning and stable structure support provide a solid foundation for the subsequent assembly process, reducing rework and waste caused by inaccurate positioning, thereby improving the overall production efficiency and product quality.
[0036] As Figure 1 shown, a plurality of first limiting members 210 are arranged on the positioning plate 120 along a first direction. Specifically, a plurality of second limiting members 220 are arranged on the positioning plate 120 along a second direction, and the second direction is perpendicular to the first direction. More specifically, the first limiting member 210 and / or the second limiting member 220 are limiting columns. More specifically, at least one first limiting member 210 is arranged close to the second limiting member 220.
[0037] It can be understood that on the positioning plate 120, a plurality of first limiting members 210 are arranged along the first direction. These limiting members are mainly used to limit the movement of the placed object in a certain dimension. At the same time, a plurality of second limiting members 220 are arranged along the second direction perpendicular to the first direction, thus forming a double limit in two perpendicular directions. The limiting column is selected as the first limiting member 210 or / and the second limiting member 220 because the limiting column has the characteristics of simple structure, easy manufacturing and installation, and can provide stable support and limiting effect. The height and diameter of the limiting column can be adjusted according to the size and positioning requirements of the specific product to achieve the best limiting effect. And at least one first limiting member 210 is arranged close to the second limiting member 220. This layout design enables the placed object at a specific position to be limited by the limiting effect from two directions at the same time, thereby improving the stability and accuracy of positioning. In addition, this closely matched layout also helps to reduce the positioning deviation or shaking problems caused by too large a spacing between the limiting members. By arranging a plurality of limiting members on the positioning plate 120, and these limiting members can be arranged and adjusted along two perpendicular directions, the positioning mechanism can be adapted to more types and sizes of mobile phone middle frames and other similar products. When it is necessary to replace and produce products of different sizes or shapes, simply adjusting the position or quantity of the limiting members can meet the new positioning requirements, without large-scale modification or replacement of the entire positioning mechanism.
[0038] As Figure 1 shown, the first positioning member 310 includes a first driver 3110 and a first abutting portion 3120 connected to the first driver 3110, and the first driver 3110 is connected to the positioning plate 120. Specifically, the second positioning member 320 includes a second driver 3210 and a second abutting portion 3220 connected to the second driver 3210, and the second positioning member 320 is connected to the positioning plate 120 through a connecting member 3230. More specifically, both the first driver 3110 and the second driver 3210 are air cylinders.
[0039] It can be understood that the first positioning member 310 is composed of a first driver 3110 and a first abutting portion 3120. This structure enables the positioning process to be more precise and controllable. The first driver 3110, as the power source, is responsible for driving the first abutting portion 3120 to move towards the placed article to achieve pushing and positioning of it. The first driver 3110 is directly connected to the positioning plate 120, ensuring stable transmission of the driving force and the accuracy of positioning. This connection method also enables the first positioning member 310 to be firmly fixed on the positioning plate 120, and is not prone to displacement or loosening. The second positioning member 320 is composed of a second driver 3210 and a second abutting portion 3220, but its connection method is slightly different. The second positioning member 320 is connected to the positioning plate 120 through a connecting member 3230. This design provides more flexibility and adjustment space. The connecting member 3230 can be adjustable to adjust the position and angle of the second positioning member 320 according to actual needs.
[0040] In this way, through the setting of the connecting member 3230, the second positioning member 320 can better adapt to the middle frames of mobile phones or other products of different sizes and shapes, enhancing the versatility and compatibility of the positioning mechanism. Both the first driver 3110 and the second driver 3210 are selected as air cylinders because air cylinders have the characteristics of simple structure, fast response speed, large thrust and easy control. As the power source, the air cylinder can quickly and accurately push the abutting portion towards the placed article to achieve rapid positioning. The use of the air cylinder also makes the entire positioning mechanism more compact and efficient, reducing energy consumption and maintenance costs. At the same time, the reliability and durability of the air cylinder have also been widely recognized and are applicable to various industrial environments. When positioning the middle frame or other products, first place the product in the placement area 1210 on the positioning plate 120. Then, the first driver 3110 and the second driver 3210 are started simultaneously, respectively driving the first abutting portion 3120 and the second abutting portion 3220 to move towards the product. As the abutting portion continuously pushes, the product gradually abuts against the first limiting member 210 and the second limiting member 220 to achieve precise positioning. Finally, the adsorption assembly 40 is started to adsorb and fix the product to ensure its stability during subsequent processing or transportation.
[0041] Such as Figure 1As shown, the adsorption assembly 40 includes a plurality of suction cups 410. More specifically, the suction cups 410 can be relatively evenly arranged in the middle of the positioning plate 120. Among them, the design of the plurality of suction cups 410 can disperse the adsorption force, making the force borne by each suction cup 410 more uniform, thereby improving the overall adsorption stability and reliability. This decentralized adsorption method can better adapt to products of different shapes and sizes than a single large suction cup 410, ensuring that the product can be firmly adsorbed on the positioning plate 120. The suction cups 410 are relatively evenly arranged in the middle of the positioning plate 120, which helps to maintain the balance and stability of the product during the adsorption process. When the suction cups 410 work simultaneously, they will act together on the central area of the product, reducing the offset or tilt phenomenon caused by uneven adsorption force, thereby improving the positioning accuracy. The automated operation of the adsorption assembly 40 makes the product positioning process more simple and fast. Once the product is placed on the positioning plate 120 and preliminarily positioned by the limiting member and the positioning member, the adsorption assembly 40 can be quickly activated and firmly adsorb the product. This fast and stable adsorption method not only improves the production efficiency, but also reduces the operation difficulty and labor cost. Since the suction cups 410 are evenly distributed and can be adjusted or replaced according to actual needs, the adsorption assembly 40 can be adapted to more types and sizes of mobile phone middle frames and other products. This design makes the positioning mechanism more flexible on the production line and can easily meet the positioning requirements of different products. The suction cups 410 can be made of soft materials such as silica gel or rubber, and these materials will not cause scratches or damage to the product surface during the adsorption process. Therefore, the adsorption assembly 40 also has significant advantages in protecting the product surface.
[0042] Compared with the prior art, a middle frame positioning mechanism provided by an embodiment of the present invention realizes the bilateral push-press positioning of the placed article through the relative structural layout of the first positioning member and the first limiting member, and the second positioning member and the second limiting member. This mechanism of bilateral simultaneous action effectively avoids the deviation that may be caused by unilateral positioning, thereby significantly improving the positioning accuracy and ensuring the accuracy and consistency of product assembly. The positioning mechanism can be adapted to mobile phone middle frames and other similar products with different outer shape size ratios. By adjusting the positions or sizes of the limiting component and the positioning component, it can easily adapt to products of various specifications, greatly enhancing the flexibility and efficiency of the production line, and reducing the mold manufacturing cost and replacement frequency.
[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
