Embodiment

[0032] The utility model embodiment provides a general positioning mechanism of mobile phone middle frame, as Figures 1 to 5 As shown in the figure, it includes mechanism main part 10, mechanism main part 10 includes base 110 and positioning fixture 120, and positioning fixture 120 is located on base 110, and positioning fixture 120 includes positioning area 1210;First positioning component 20, first positioning component 20 is located on positioning fixture 120;Second positioning component 30, second positioning component 30 is located on one side of positioning fixture 120, and second positioning component 30 includes drive piece 310 and pressure block 320, and drive piece 310 is connected with pressure block 320, is used for driving pressure block 320 towards positioning area 1210 movement.

[0033] It can be understood that the mobile phone middle frame is placed on the positioning area 1210 of the positioning fixture 120 by artificial or mechanical hand, the first positioning component 20 is arranged on the positioning fixture 120, the second positioning component 30 is arranged on one side of the positioning fixture 120, the pressure block 320 is driven by the drive piece 310 towards the positioning area 1210, the product is tightly attached to the fixture fixed plate 130, the positioning is completed, and the product positioning function is realized. The positioning mechanism provided in the application is highly versatile and can be compatible with mobile phone middle frames of different sizes. The first positioning component 20 and the second positioning component 30 cooperate to improve positioning accuracy and stability. The second positioning component 30 is arranged on one side of the positioning fixture 120, which can reduce the impact on placing or removing the mobile phone middle frame.

[0034] The second positioning assembly 30 is arranged on one side of the positioning jig 120, which not only optimizes the pressing process and reduces the interference of the pressing block 320 when the mobile phone middle frame is placed or taken out, but also makes the whole positioning mechanism more smooth in operation, reducing the burden of the operator. At the same time, this layout is also convenient for daily maintenance and maintenance, reducing the maintenance cost. The positioning mechanism can significantly improve the processing efficiency and product quality of the mobile phone middle frame. Precise positioning ensures the smooth progress of subsequent processing steps, reduces rework and scrap caused by inaccurate positioning, thereby reducing production cost and improving overall production benefit.

[0035] As shown in Figure 4 The mechanism main body 10 also includes a fixed plate 130, and the positioning jig 120 is connected with the base 110 through the fixed plate 130. More specifically, the fixed plate 130 is arranged vertically with the base 110, and the positioning jig 120 is arranged obliquely on the fixed plate 130.

[0036] In this way, the fixed plate 130 serves as an intermediate piece connecting the positioning jig 120 and the base 110, and its vertical arrangement not only provides stable support but also effectively disperses the stress generated by the positioning jig 120 during work, enhancing the structural stability of the whole mechanism main body 10. This design makes the positioning jig 120 more stable when bearing the pressure of the pressing block 320, reducing positioning errors caused by vibration or deformation. The oblique arrangement of the positioning jig 120 on the fixed plate 130 allows the mobile phone middle frame to fit the positioning area 1210 more naturally when placed, reducing positioning deviations caused by improper angles. At the same time, the angle of inclination can also be adjusted according to the shape and size of the mobile phone middle frame to adapt to different models of mobile phone middle frames, further improving the accuracy and universality of positioning. The vertical arrangement of the fixed plate 130 and the base 110 allows the operator to more intuitively observe the state of the positioning jig 120 when placing or taking out the mobile phone middle frame, making it easier to judge whether the mobile phone middle frame has been placed correctly. In addition, the oblique positioning jig 120 also makes it easier to observe and monitor the mobile phone middle frame during processing, helping to discover and correct possible problems in a timely manner. Due to the further optimization of the arrangement of the fixed plate 130 and the positioning jig 120, the whole positioning mechanism operates more smoothly and efficiently. The operator can place and take out the mobile phone middle frame more quickly, reducing production delays caused by inaccurate positioning or inconvenient operation. At the same time, it also helps to reduce downtime caused by equipment failure or maintenance, thereby improving overall production efficiency.

[0037] As shown in Figure 3 The first positioning assembly 20 includes a plurality of first positioning pieces 210, and the first positioning pieces 210 are arranged in the positioning area 1210. More specifically, the first positioning pieces 210 can be pins.

[0038] It can be understood that the pin, as a precise positioning element, its size and position can be strictly controlled, so as to ensure the accurate placement of the mobile phone middle frame in the positioning area 1210. The cooperation of multiple pins can form multi-point positioning, effectively limit the movement of the mobile phone middle frame in horizontal and vertical directions, and significantly improve the positioning accuracy. The pin and the positioning hole or positioning surface on the mobile phone middle frame tightly cooperate to form a stable support structure. This design not only enhances the stability of positioning, but also helps to reduce the positioning deviation caused by vibration or external force interference. In addition, the rigid structure of the pin also makes the positioning more reliable and not easy to deform or fail after long-term use. As a positioning element, the installation and disassembly of the pin is relatively simple and fast. This enables the operator to quickly adjust the positioning mechanism when replacing different models of mobile phone middle frames, reducing the production preparation time. At the same time, the maintenance cost of the pin is relatively low, easy to replace and repair, reducing the overall operating cost.

[0039] As shown in Figure 3 More specifically, it can also include a suction accessory 40 arranged between the plurality of first positioning elements 210. The vacuum chuck absorbs the mobile phone middle frame by generating negative pressure, combined with the multi-point mechanical positioning of the pin, forming a more stable positioning system. This dual positioning method not only improves the accuracy of positioning, but also significantly enhances the stability of the mobile phone middle frame during processing, reducing the risk of displacement caused by vibration or external force interference. The design of the vacuum chuck has a certain flexibility, which can adapt to mobile phone middle frames with different surface materials and shapes. Compared with the rigid positioning of the pin, the vacuum chuck can better fit the curved surface or irregular shape of the mobile phone middle frame, thereby improving the versatility and adaptability of positioning. The suction effect of the vacuum chuck makes it more convenient to place and take out the mobile phone middle frame. The operator only needs to control the switch of the vacuum system to easily realize the quick positioning and release of the mobile phone middle frame, reducing the complexity and time cost of manual operation and improving the production efficiency. The vacuum chuck tightly adheres to the positioning jig 120 through the suction effect, reducing the positioning error caused by the gap or friction between the mobile phone middle frame and the positioning jig 120. This tight fit also helps to improve the accuracy and consistency of subsequent processing steps. As a mature industrial element, the vacuum chuck is easy to integrate with the existing positioning mechanism. At the same time, its maintenance is relatively simple, and only needs to be checked and cleaned regularly to ensure its normal work.

[0040] As shown in Figure 2 The second positioning assembly 30 is connected to the positioning jig 120 through the first connecting element 50. In this way, the connection relationship between the first connecting element 50, the second positioning assembly 30 and the positioning jig 120 can be adjusted to better realize the movement of the driving block 320 driven by the driving element 310.

[0041] The first connecting piece 50 can be used to conveniently adjust the relative position relationship between the second positioning assembly 30 and the positioning jig 120. This flexibility in adjustment enables the positioning mechanism to better adapt to mobile phone middle frames of different sizes and shapes, ensuring that the pressing block 320 can be accurately and stably pressed onto the mobile phone middle frame, achieving high-precision positioning. The pressing angle, force, and position of the second positioning assembly 30 can be fine-tuned through the first connecting piece 50, thereby optimizing the pressing effect. This fine-tuning capability helps to reduce deformation or damage to the mobile phone middle frame caused by improper pressing, improving the processing quality and yield of the product. The first connecting piece 50 not only serves a connecting function, but also disperses the stress and vibration generated during the pressing process of the pressing block 320, enhancing the stability of the entire positioning mechanism. This stability is crucial for ensuring high-precision positioning and long-term stable operation. Through the first connecting piece 50, the second positioning assembly 30 can be more easily connected and detached from the positioning jig 120. This simplifies the installation and maintenance process, reducing the difficulty and cost for the operator. At the same time, the first connecting piece 50 also facilitates inspection and replacement, helping to extend the service life of the positioning mechanism. Since the first connecting piece 50 allows for quick adjustment of the position and pressing parameters of the second positioning assembly 30, the operator can more quickly adapt to different models of mobile phone middle frames, reducing production preparation time. This flexibility helps to improve production efficiency and shorten the product launch cycle.

[0042] As shown in Figure 5 , the pressing block 320 is rotationally connected to the driving piece 310 through the second connecting piece 330. More specifically, the second connecting piece 330 is rotationally connected to the driving piece 310 through the third connecting piece 340.

[0043] It can be understood that the second connecting piece 330 serves as an intermediary between the pressing block 320 and the driving piece 310, allowing the pressing block 320 to move more flexibly under the drive of the driving piece 310. In particular, when the pressing block 320 needs to adapt to different shapes and sizes of the mobile phone middle frame, such flexibility is particularly important. By adjusting the angle and position of the second connecting piece 330, it can be ensured that the pressing block 320 can be accurately and stably pressed on the mobile phone middle frame, achieving high-precision positioning. The combination of the second connecting piece 330 and the third connecting piece 340 allows the force and distribution of the pressing block 320 during the pressing process to be more finely controlled. By adjusting the parameters of the connecting pieces, such as length, angle, and material, the pressing effect of the pressing block 320 can be optimized, reducing the deformation or damage of the mobile phone middle frame caused by uneven pressing force. The introduction of the second connecting piece 330 and the third connecting piece 340 disperses the stress and vibration generated during the pressing process of the pressing block 320, thereby enhancing the reliability and durability of the entire positioning mechanism. This design helps to reduce equipment failures and maintenance costs caused by long-term use or harsh working environments. Through the rotary connection of the second connecting piece 330 and the third connecting piece 340, the driving piece 310 can more directly drive the pressing block 320 to move without the need for complex transmission mechanisms.

[0044] More specifically, the driving piece 310 can be a pneumatic cylinder, and the movement direction of the driving piece 310 is perpendicular to the positioning area 1210. The second positioning assembly 30 can be understood as a pressing link pneumatic cylinder. In this way, by placing the mobile phone middle frame on the positioning area 1210 by hand or mechanical hand, there are three positioning pins on the positioning area 1210 to achieve product positioning function, and the pressing link pneumatic cylinder is pressed down to tightly attach the product to the positioning fixture 120, completing the positioning. The pin positioning and pressing pneumatic cylinder achieve complete positioning of the product, improving positioning accuracy and stability.

[0045] In this way, through the precise layout of multiple positioning pins on the positioning area 1210, the mobile phone middle frame can be accurately placed and positioned. Multi-point positioning ensures the stability and consistency of the product during processing, improving positioning accuracy. The pressing link cylinder's downward movement tightly fits the product with the positioning fixture 120, effectively preventing displacement caused by vibration or external force interference during processing. This tight fit not only improves the stability of positioning, but also helps to reduce processing errors. Artificial or mechanical hands can easily place the mobile phone middle frame on the positioning area 1210, and then the pressing link cylinder automatically presses down to complete positioning. This reduces the complexity and time cost of manual operation, improving production efficiency. Different sizes and shapes of mobile phone middle frames can be adapted by adjusting the position and number of positioning pins. At the same time, the stroke and force of the pressing link cylinder can also be adjusted according to actual needs to meet the processing needs of different products. As a mature industrial element, the cylinder has a simple structure and is easy to maintain. When maintenance or replacement is needed, relevant parts can be easily disassembled and replaced, reducing maintenance cost and time.

[0046] Compared with the prior art, the universal positioning mechanism for mobile phone middle frames provided by the embodiments of the present application realizes multi-point positioning of the mobile phone middle frame by combining the first positioning assembly 20 and the second positioning assembly 30. The first positioning assembly 20 preliminarily fixes the approximate position of the mobile phone middle frame, and the second positioning assembly 30 precisely presses the block 320 through the driving of the driving member 310, ensuring that the mobile phone middle frame is tightly fitted with the positioning fixture 120, effectively reducing positioning deviation caused by manufacturing tolerances or improper human operation, thereby significantly improving positioning accuracy and stability. The positioning fixture 120, the positioning area 1210 thereon, the first positioning assembly 20 and the second positioning assembly 30 all have sufficient adjustability and adaptability, and can be compatible with mobile phone middle frames of different sizes. This means that on the same production line, without frequent replacement of the positioning fixture 120, various models of mobile phone middle frames can be easily processed, significantly improving the flexibility and efficiency of the production line.

[0047] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application.
