Abstract
Description
Technical Field
[0001] This invention relates to the field of mobile phone front shell shaping technology, specifically to an automated mobile phone front shell shaping device and method. Background Technology
[0002] The front shell of a mobile phone is a core structural component and exterior carrier of modern smartphones. It is usually manufactured using a one-piece molding process of a metal frame and injection-molded plastic. It uses a high-strength aluminum-magnesium alloy frame as a skeleton, and the plastic material is fused to a specific area of the frame through precision injection molding to form a composite component that serves as a support structure, antenna signal window, and assembly reference surface for internal components. Due to the internal stress generated by the cooling and shrinkage of the plastic during the injection molding process, the front shell will inevitably warp or bend. This deformation will cause optical interference to the screen that is subsequently mounted, resulting in display defects such as moiré patterns or screen distortion. Therefore, unibody molding is an indispensable key process before the screen is assembled into the front shell.
[0003] In the existing technology, the automated workflow for shaping the front shell of a mobile phone first uses a robotic arm to pick up the part from the material area, put the front shell to be shaped into and position it in the shaping fixture, then triggers the start switch to press down the upper shaping mold and maintain constant pressure for about three seconds to correct the deformation. After the pressure holding is completed, the upper mold automatically resets, and then the robotic arm takes out the shaped front shell and neatly stacks it into a blister pack, completing a single operation cycle.
[0004] However, after shaping, the product may get stuck in the fixture due to vacuum adsorption or slight deformation. Vacuum adsorption may form between the plastic surface and the metal fixture, or the product may undergo slight elastic deformation after shaping, causing it to get stuck in the lower mold fixture. This makes it difficult for the robot to move around in the space, which will affect efficiency and easily scratch the product. It will also reduce the production cycle, increase equipment downtime, and cause scratches on the plastic surface, scratches on the metal frame, or damage to the coating during the forced removal process.
[0005] Although it is possible to remove the product after it has been shaped and moved upwards, the product is in a positional change state when the product is being shaped. This state of change cannot be limited. Therefore, if the lifting height is too high or unstable, the robot arm may easily knock over the product or cause it to slip when it removes the product, resulting in secondary damage or downtime. This will also increase the defect rate and rework costs, and cause frequent production line shutdowns and equipment idling, which will seriously disrupt the continuity and cycle balance of automated production. Summary of the Invention
[0006] To address the shortcomings of existing technologies, this invention provides an automated shaping device for mobile phone front shells. This device has the advantages of disrupting the product's state by moving upwards after shaping, thereby facilitating easy removal of the part, and limiting the movement of the device when disrupting the product's state, thus solving the problems mentioned in the background technology.

[0009] Preferably, the limiting mechanism includes a receiving block, a fixing screw, a second fixing rod, a second sliding block, a rectangular block, and a rounded corner block. The bottom of the receiving block is fixedly installed on the left side of the upper surface of the operating table. The outer surface of the fixing screw is threadedly connected to the inner wall of the receiving block and the outer surface of the fixing screw is also threadedly connected to the inner wall of the operating table. One end of the second fixing rod is fixedly installed on the top of the inside of the operating table. The inside of the second sliding block is slidably connected to the outer surface of the second fixing rod. The bottom of the rectangular block is fixedly installed on the upper surface of the second sliding block. One side of the rounded corner block is fixedly installed on the inside of the receiving block.
[0010] Preferably, the right side of rack one meshes with the outer surface of gear one, and the right side of rack two meshes with the outer surface of gear two.
[0011] Preferably, a connecting spring is fixedly installed at the top of the inside of the operating table, and a telescopic rod is fixedly installed at the top of the inside of the operating table.
[0012] Preferably, a fixing rod is fixedly installed at the top of the inside of the operating table, and a sliding block is slidably connected to the outer surface of the fixing rod. The bottom of the sliding block is fixedly connected to one end of the connecting spring and the telescopic rod.
[0013] Preferably, a placement fixture is fixedly installed on the left side of the sliding block, and the placement fixture has a placement groove inside.
[0014] Preferably, in the initial state, the shaping plate drives the rack to be placed at the bottom of the gear for shaping. After the shaping operation is completed, the hydraulic cylinder drives the shaping plate to engage the rack and gear, so that the rack is positioned above the gear.
[0015] Preferably, the rectangular block has a groove inside, and the inside of the groove engages with the outer surface of the rounded corner block.
[0016] An automated shaping method for mobile phone front covers includes the following specific steps: S1. The robotic arm precisely places the front shell of the phone to be shaped into the placement slot of the fixture, ensuring that it is aligned with the fixture's positioning reference. S2. Start the hydraulic cylinder, drive the connecting plate to move the shaping pressure plate downward, apply the set pressure to the front shell of the phone and hold the pressure for a few seconds. At the same time, rack 1 moves downward with the connecting plate. S3. The hydraulic cylinder drives the shaping plate to return and rise. Rack 1 meshes with gear 1 for transmission. Through the rotating rod, gear 2 drives rack 2 to move horizontally, pushing the L-shaped frame to lift sliding block 1 along fixed rod 1. This allows the placement fixture to carry the product to the picking position. At this time, the groove of the rectangular block engages and locks with the rounded corner block. S4. After the robotic arm grabs the product at the locked and stable picking station, it moves out and triggers the reset device to release the groove and the rounded corner block. The placement fixture is lowered and reset under the action of the connecting spring, and all mechanisms return to their initial state.
[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This automated shaping equipment for mobile phone front shells drives rack one when the shaping platen moves upward, and rack two moves horizontally through gear one, rotating rod, and gear two, smoothly lifting the placement fixture. This linkage upward movement mechanism automatically completes product demolding, eliminating product jamming caused by vacuum adsorption or micro-deformation, and avoiding the risk of scratches caused by the robotic arm forcibly picking up the parts. Secondly, when the lifting action ends, the limiting mechanism composed of rectangular blocks and rounded corner blocks achieves mechanical self-locking, accurately fixing the placement fixture and product at the preset picking height, forming a stable and reliable suspended picking state, preventing the product from tipping over or slipping due to unstable lifting height, and ensuring the success rate of picking and product safety.
[0018] 2. This type of automated shaping equipment for mobile phone front shells features a single, integrated hydraulic cylinder drive structure. Ejection and positioning require no additional power source or complex electrical control intervention. Its simple and reliable structure results in low maintenance costs. The stable part-picking state standardizes the robotic arm's gripping program, improving the stability and repeatability of the production cycle and reducing production line downtime due to part-picking failures. Simultaneously, the mechanical hard limit avoids potential misjudgments or drift issues that may occur with sensors, enhancing the equipment's stability and durability during long-term operation. This provides a solid foundation for achieving efficient, high-yield, continuous automated production. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An automated shaping device for mobile phone front shells includes an operating table 1. A vertical frame 2 is fixedly installed on the upper surface of the operating table 1. An extension frame 3 is fixedly installed on the front of the vertical frame 2. A hydraulic cylinder 4 is installed on the upper surface of the extension frame 3. A connecting plate 5 is fixedly installed at one end of the output shaft of the hydraulic cylinder 4. A shaping pressure plate 6 is installed on the lower surface of the connecting plate 5. A linkage upward moving mechanism is provided on the right side of the connecting plate 5. A limiting mechanism that converts the upward force into a limiting force is provided at the power output end of the linkage upward moving mechanism. The linkage upward moving mechanism includes a receiving frame 7 and a rack. 8. Fixing block 9, rotating rod 10, gear one 11, gear two 12, limiting block 13, rack two 14, and L-shaped frame 15. The left side of the receiving frame 7 is fixedly installed with the right side of the connecting plate 5. The left side of rack one 8 is fixedly installed with the right side of the receiving frame 7. The bottom of fixing block 9 is fixedly installed with the upper surface of the operating table 1. The outer surface of rotating rod 10 is rotatably connected to the inner wall of fixing block 9. The inside of gear one 11 is fixedly installed with the outer surface of rotating rod 10. The inside of gear two 12 is fixedly installed with the outer surface of rotating rod 10. Limiting block 13... The bottom of the rack is fixedly installed on the upper surface of the operating table 1. The inside of the rack 14 is slidably connected to the outer surface of the limit block 13. The right side of the L-shaped frame 15 is fixedly installed on the left side of the rack 14. The right side of the rack 8 meshes with the outer surface of the gear 11. The right side of the rack 14 meshes with the outer surface of the gear 12. A connecting spring 20 is fixedly installed at the top inside the operating table 1. A telescopic rod 21 is fixedly installed at the top inside the operating table 1. A fixing rod 16 is fixedly installed at the top inside the operating table 1. The outer surface of the fixing rod 16 slides. A sliding block 17 is connected, and the bottom of the sliding block 17 is fixedly connected to one end of the connecting spring 20 and the telescopic rod 21. A placement fixture 18 is fixedly installed on the left side of the sliding block 17. The placement fixture 18 has a placement groove 19 inside. In the initial state, the shaping plate 6 drives the rack 8 to be placed at the bottom of the gear 11 for shaping operation. After the shaping operation is completed, the hydraulic cylinder 4 drives the shaping plate 6 to engage the rack 8 with the gear 11, so that the rack 8 is positioned above the gear 11.
[0023] Specifically, during the shaping process, the shaping plate 6, under the stable drive of the hydraulic cylinder 4, can precisely shape the front shell of the mobile phone. The linkage upward movement mechanism, through the precise transmission of components such as rack 8, gear 11, gear 12, and rack 14, enables the limiting mechanism to accurately convert the upward force into a limiting force, precisely controlling the shaping process of the mobile phone front shell and ensuring the dimensional and shape accuracy of the shaped front shell. The equipment's components are compactly arranged; the operating table 1 serves as the basic support structure, on which components such as the vertical frame 2 and extension frame 3 are rationally installed, providing a stable mounting position for the hydraulic cylinder 4 and the linkage upward movement mechanism. The supporting frame 7, fixing block 9, and rotating rod 10 in the linkage upward movement mechanism cooperate to form a compact transmission system, ensuring both transmission stability and space saving.
[0024] Please see Figure 1 , Figure 6 and Figure 7 The limiting mechanism includes a receiving block 22, a fixing screw 23, a second fixing rod 25, a second sliding block 26, a rectangular block 27, and a rounded corner block 28. The bottom of the receiving block 22 is fixedly installed on the left side of the upper surface of the operating table 1. The outer surface of the fixing screw 23 is threadedly connected to the inner wall of the receiving block 22 and the outer surface of the fixing screw 23 is threadedly connected to the inner wall of the operating table 1. One end of the second fixing rod 25 is fixedly installed on the top of the inside of the operating table 1. The inside of the second sliding block 26 is slidably connected to the outer surface of the second fixing rod 25. The bottom of the rectangular block 27 is fixedly installed on the upper surface of the second sliding block 26. One side of the rounded corner block 28 is fixedly installed on the inside of the receiving block 22. The inside of the rectangular block 27 is provided with a groove 24, and the inside of the groove 24 is engaged with the outer surface of the rounded corner block 28.
[0025] Specifically, the limiting mechanism uses the engagement of rectangular block 27 and rounded corner block 28. During the upward movement of the linkage mechanism, when the relevant components rise to a specific position, the rounded corner block 28 can accurately engage with the groove 24 of the rectangular block 27, achieving precise limiting. This ensures that the shaping plate 6 stops after completing the shaping operation and rising to the appropriate position, preventing excessive rising or falling, thus ensuring the accuracy of the phone front shell shaping process and ensuring that the size and shape of the shaped product meet the design requirements. The receiving block 22 is firmly connected to the operating table 1 by fixing screws 23, providing a stable installation base for the entire limiting mechanism. The second fixing rod 25 is fixed to the top of the inside of the operating table 1, and the second sliding block 26 slides on its outer surface. This structural design makes the sliding process of the second sliding block 26 stable and smooth, thereby ensuring that the rectangular block 27 can accurately cooperate with the rounded corner block 28, improving the reliability and stability of the limiting mechanism, and reducing malfunctions and errors during equipment operation.
[0026] An automated shaping method for mobile phone front covers includes the following specific steps: S1. The robotic arm precisely places the front shell of the phone to be shaped into the placement slot 19 of the placement fixture 18, ensuring that it fits the positioning reference of the fixture. S2. Start hydraulic cylinder 4, drive connecting plate 5 to drive shaping pressure plate 6 to press down, apply set pressure to the front shell of the mobile phone and hold the pressure for 3 seconds. At the same time, rack 8 moves down with connecting plate 5. S3, hydraulic cylinder 4 drives the shaping plate 6 to rise during the return stroke, rack 8 meshes with gear 11 for transmission, and through rotating rod 10, gear 12 drives rack 14 to move horizontally, pushing L-shaped frame 15 to lift sliding block 17 along fixed rod 16, so that the placement fixture 18 carries the product to the picking position. At this time, the groove 24 of rectangular block 27 engages and locks with rounded corner block 28. S4. After the robotic arm grabs the product at the locked and stable picking station, it moves out and triggers the reset device to release the engagement between the groove 24 and the rounded corner block 28. The placement fixture 18 descends and resets under the action of the connecting spring 20, and all mechanisms return to their initial state.
[0027] Working principle: In the initial state, the shaping pressure plate 6 and rack 8 are in the low position. After the front shell of the mobile phone is placed into the placement slot 19 of the placement fixture 18, the hydraulic cylinder 4 is activated. The hydraulic cylinder 4 drives the connecting plate 5 and the shaping pressure plate 6 to press down, applying pressure to the front shell for shaping. At the same time, the receiving bracket 7 fixed on the connecting plate 5 drives the rack 8 to move down synchronously. After the shaping and pressure holding are completed, the hydraulic cylinder 4 drives the shaping pressure plate 6 to move up and reset. The rack 8 then rises and meshes with the gear 11, driving the rotating rod 10 to rotate. Gear 12 on 10 rotates synchronously, driving rack 14, which meshes with it, to slide horizontally to the left under the constraint of limit block 13. Rack 14 pushes sliding block 17 upward along fixed rod 16 through L-shaped frame 15, thereby smoothly lifting the entire placement fixture 18 and its internal shaped front shell, breaking the vacuum adsorption state and putting the product in a suspended state for easy removal. During the lifting process of placement fixture 18, sliding block 17 will compress connecting spring 20 and telescopic rod 21. At the same time, sliding block 17 or fixture connection The movable rectangular block 27 rises accordingly. When it reaches the preset height, i.e., the part-retrieving station, the groove 24 on the rectangular block 27 engages precisely with the rounded corner block 28 fixed on the receiving block 22. Under the reset pressure of the connecting spring 20, a mechanical self-locking mechanism is formed. This limiting mechanism precisely locks the end point of the lifting action, ensuring that the product is lifted to the same stable height each time, and that the placement fixture 18 itself is fixed and will not shake. At this point, the robotic arm can safely and accurately complete the part-retrieving operation from above the limited and stable suspended product. To effectively prevent products from tipping over or slipping, after the product is picked up, the control system issues a command, possibly through a small cylinder or electromagnet, to release the engagement between the groove 24 and the rounded corner block 28. Subsequently, under the restoring force of the connecting spring 20 and the telescopic rod 21, the sliding block 17 drives the placement fixture 18 to descend and reset. At the same time, the hydraulic cylinder 4 may continue a small stroke to disengage the rack 8 from the gear 11, or during the next cycle of pressing down, the mechanism automatically resets to the initial state, ready for the shaping operation of the next product.
[0028] In this equipment, hydraulic cylinder 4 can be a servo hydraulic cylinder with a rated output of 5-10 tons and a stroke of 100-150mm, such as the YUKEN series. The forming plate 6 is made of S136 mold steel after heat treatment and is equipped with a hard alloy pressure head with a flatness of ≤0.01mm. The placement fixture 18 is made of NAK80 mold steel with precision machining and the cavity surface is treated with Teflon coating. During operation, three-phase 380V AC power drives the hydraulic station motor through a frequency converter to power hydraulic cylinder 4. At the same time, the PLC control system controls the hydraulic proportional valve through 24V DC power. To achieve precise pressing and pressure holding of the shaping plate 6, when the hydraulic cylinder 4 returns, its piston rod drives the connecting plate 5 to move upward. Through the rack 8 fixed on it, the gear 11 is driven to rotate. The torque is transmitted through the rotating rod 10 to make the gear 12 rotate synchronously. Then, the L-shaped frame 15 fixed to the rack 14 pushes the sliding block 17 vertically up along the fixed rod 16. Finally, the placement fixture 18 carries the product to the part-removing station where the rectangular block 27 and the rounded corner block 28 are engaged and locked. At this time, the robot arm completes stable part removal with the help of the vacuum generator driven by 24V DC.
