They are no longer just electronic devices for communication purposes, but multimedia phones that integrate music, video, photography, internet access and other functions. Among the components of mobile phones, the mid-frame is used to fix important components such as the circuit board, battery and screen. With the continuous development of smartphones, the processing of the mid-frame has become more and more important. Using metal materials for the mid-frame not only has a beautiful appearance, but also has the advantages of delicate feel, wear resistance, drop resistance, corrosion resistance and easy recycling. Because of this, it is very popular among consumers. As an important part of the mobile phone, the mid-frame has a smooth exterior and a relatively complex internal structure.

[0003] The mid-frame of a mobile phone is the area connecting the front panel and the back cover.

[0041] This application provides a cooling and shaping device for the injection-molded mid-frame of a mobile phone, solving the technical problems of long cooling waiting cycles and low production efficiency in the prior art. The blower assembly 8 blows air into the inner cavity of the cooling chamber 4 through the second water-cooling assembly 7, and the exhaust mechanism exhausts air from the inner cavity of the cooling chamber 4 through the first water-cooling assembly 5, realizing air flow in the cooling chamber 4. In conjunction with the first water-cooling assembly 5 and the second water-cooling assembly 7, the air flow allows more cold air to be distributed in the cooling chamber 4 for cooling, effectively improving the cooling effect and helping to improve production efficiency.

[0042] This application provides a cooling and shaping device for the injection-molded mid-frame of a mobile phone, comprising a frame 1 and a cooling device 2 mounted on the frame 1. A chain conveyor 3 is also mounted on the frame 1. The cooling device 2 includes a cooling chamber 4, an exhaust cooling mechanism mounted above the cooling chamber 4, and blower cooling mechanisms mounted on both sides of the cooling chamber 4. The exhaust cooling mechanism includes a first water-cooling component 5 and multiple exhaust components 6 arranged in a row at equal intervals above the cooling chamber 4, with the first water-cooling component 5 positioned below the multiple exhaust components 6. The blower cooling mechanism includes a second water-cooling component 7 and multiple exhaust components 6 arranged in a row at equal intervals. The blower assembly 8 on the side wall of the cooling chamber 4 and the second water-cooling assembly 7 are arranged inside the multiple blower assemblies 8; the exhaust assembly 6 is an exhaust fan and the blower assembly 8 is a blower fan; the cooling chamber 4 is provided with an inner cavity, with air inlets 9 on both sides of the inner cavity and an air outlet 10 at the upper end of the inner cavity. The air inlets 9 are corresponding to the blower cooling mechanism and the air outlet 10 is corresponding to the exhaust cooling mechanism; the chain conveyor passes through the inner cavity of the cooling chamber 4, and the front and rear ends of the cooling chamber 4 are respectively provided with a feed inlet 11 and a discharge outlet communicating with the inner cavity; multiple middle frame support mechanisms 12 are evenly distributed and installed on the chain conveyor along its transmission direction. Specifically, after the external processing equipment injection molds the mobile phone mid-frame, it is transferred to the mid-frame support mechanism 12 of the chain conveyor. Each mid-frame support mechanism 12 supports one mobile phone mid-frame. The chain conveyor transfers the mid-frame support mechanism 12 into the inner cavity of the cooling chamber 4 through the feed port 11. After entering the inner cavity, the blower assembly 8 operates, blowing air into the inner cavity of the cooling chamber 4 through the air inlet 9. The air flows through the second water-cooling assembly 7 into the inner cavity of the cooling chamber 4. At the same time, the exhaust assembly 6 operates, extracting air from the cooling chamber 4 through the air outlet 10 and the first water-cooling assembly 5. Continuous blowing ensures continuous airflow within the cooling chamber 4. The first water-cooling component 5 and the second water-cooling component 7 cool the air entering the cooling chamber 4, improving its cooling effect. Multiple exhaust components 6 are arranged in a row at equal intervals in the middle of the upper part of the cooling chamber 4. The exhaust components 6 are located directly above the middle frame support mechanism 12. The blower component 8 blows air toward the middle frame support mechanism 12, and the exhaust components 6 draw air upwards from the middle frame support mechanism 12, resulting in faster airflow and better cooling effect.

[0043] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0044] In this embodiment, a first filter 19 is provided at the air outlet 10, and a second filter 20 is provided at the air inlet 9. Specifically, the first filter 19 and the second filter 20 can filter dust particles, reduce dust in the cooling chamber 4, avoid excessive contamination of the phone frame, simplify subsequent cleaning of the phone frame, and improve production quality.

[0045] In this embodiment, a feed sensor 42 is provided at the feed inlet 11, and a discharge sensor is provided at the discharge outlet to detect the middle frame support mechanism 12. A control device is also provided on the frame 1. The control device is electrically connected to the chain conveyor 3, the blower assembly 8, and the exhaust assembly 6, respectively. The control device is equipped with a communication module that is connected to the feed sensor 42 and the discharge sensor. The feed sensor 42 is used to detect the number of middle frame support mechanisms 12 entering the cooling chamber 4, and the discharge sensor is used to detect the number of middle frame support mechanisms 12 exiting the cooling chamber 4. When the number of mid-frame support mechanisms 12 entering the cooling chamber 4 reaches the preset cooling quantity threshold, the chain conveyor 3 is stopped, so that the exhaust cooling mechanism and the blower cooling mechanism can cool the mobile phone mid-frame on the mid-frame support mechanism 12. When the cooling time reaches the preset cooling time threshold, the cooling is completed, the chain conveyor 3 is started, and the mid-frame support mechanism 12 in the cooling chamber 4 is sent out. The discharge sensor can detect the number of mid-frame support mechanisms 12 that have left the cooling chamber 4. At the same time, the next batch of mid-frame support mechanisms 12 enters the cooling chamber 4 to facilitate the next round of cooling.

[0046] In this embodiment, the first lifting plate 22 is provided with a plurality of CCD positioning holes 49, which facilitates external devices to perform positioning by cooperating with the CCD camera and the CCD positioning holes 49, thereby ensuring the accuracy of transferring the mobile phone frame to the annular support fixture 21.

[0047] Furthermore, to improve the reliability and cooling effect of the exhaust cooling mechanism and the blower cooling mechanism, the blower assembly 8 remains open and continuously blows air while the cooling chamber 4 is working. When a batch of hollow support structures with a preset cooling quantity threshold enters the inner cavity of the cooling chamber 4, the blower assembly 8 continues to blow air. The feeding sensor 42 detects the time it takes for a batch of hollow support structures to enter the cooling chamber 4. When the time for each batch of hollow support structures to enter the cooling chamber 4 reaches the preset exhaust start time threshold, the exhaust assembly 6 is activated by the control device. When the cooling time reaches the preset cooling time threshold, cooling is complete, the chain conveyor 3 starts, and the middle frame support structure 12 in the cooling chamber 4 is discharged. The sensor can detect the number of mid-frame support mechanisms 12 exiting the cooling chamber 4. When the number of mid-frame support mechanisms 12 exiting the cooling chamber 4 reaches a preset cooling quantity threshold, the control device drives the exhaust assembly 6 to stop. At the same time, the next batch of mid-frame support mechanisms 12 enters the cooling chamber 4. When the time it takes for them to enter the cooling chamber 4 reaches a preset exhaust start time threshold, the control device starts the exhaust assembly 6 to work. Under the above settings, the blower assembly 8 can work first, filling the area around the mid-frame support mechanisms 12 with air for cooling, and then the exhaust assembly 6 can be turned on to work, increasing the airflow speed and thus improving the cooling effect. At the same time, the exhaust assembly 6 does not need to work continuously, effectively saving resources.

[0048] Furthermore, a feed gate plate 43 and a feed gate plate 43 drive assembly for driving the feed gate plate 43 to rise and fall are installed at the feed inlet 11; a discharge gate plate and a discharge gate plate drive assembly for driving the discharge gate plate to rise and fall are installed at the discharge outlet; both the feed gate plate 43 drive assembly and the discharge gate plate drive assembly are transmission structures consisting of a motor 44 and a lead screw 45, which is existing technology. A lifting collar 46 is provided on one side of the feed gate plate 43, and the lifting collar 46 is threaded onto the outer circumference of the lead screw 45. The lifting collar 46 slides against one side of the inner wall of the cooling chamber 4. A guide sleeve 47 is provided on the other side of the feed gate plate 43, and the guide sleeve 47 slides against the other side of the inner wall of the cooling chamber 4, or the inner wall of the cooling chamber 4. On the other side, a lifting guide rod 48 is provided, and a guide sleeve 47 is slidably sleeved on the lifting guide rod 48. The feeding gate plate 43 drive assembly and the discharging gate plate drive assembly are existing technologies and will not be described in detail here. The structure of the discharging gate plate drive assembly is the same as that of the feeding gate plate 43 drive assembly. In the initial state, the feeding gate plate 43 drive assembly and the discharging gate plate drive assembly drive the feeding gate plate 43 and the discharging gate plate to rise respectively. When a batch of hollow support mechanisms with a preset cooling quantity threshold enters the inner cavity of the cooling chamber 4, the feeding gate plate 43 drive assembly and the discharging gate plate drive assembly drive the feeding gate plate 43 and the discharging gate plate to fall respectively, blocking the feeding port 11 and the discharging port, improving the shielding effect, and helping to improve the cooling effect.

[0049] In this embodiment, two first water-cooling components 5 are provided, arranged side by side and facing each other. Each first water-cooling component 5 includes a first water inlet 13, a first water outlet 14, and a first water-cooling pipe 15. The first water-cooling pipe 15 is arranged in a serpentine pattern. Both the first water inlet 13 and the first water outlet 14 are installed above the outer wall of the cooling chamber 4. The first water inlet 13 is connected to the first water outlet 14 via the first water-cooling pipe 15, which is installed inside the air outlet 10. Specifically, under the above configuration, the first inlet 13 is used to connect one end of the external water tank and the first water pump. The water pump draws water into the first inlet 13, which then enters the first water-cooling pipe 15. The first outlet 14 is used to discharge water into the water tank at the other end of the external water tank, thereby realizing water circulation for water cooling of the first water-cooling component 5. Preferably, each first water-cooling component 5 has multiple first water-cooling pipes 15, which are arranged in multiple layers and interconnected. Under the above configuration, the water cooling effect can be further improved. The first water-cooling component 5 is mainly used to reduce the ambient air temperature in order to achieve a better cooling effect.

[0050] In this embodiment of the application, the second water-cooling component 7 includes a second water inlet 16, a second water outlet 17, and a second water-cooling pipe 18. The second water-cooling pipe 18 is arranged in a serpentine manner. The second water inlet 16 is connected to the second water outlet 17 through the second water-cooling pipe 18. The second water inlet 16 and the second water outlet 17 are respectively installed on the side of the outer wall of the cooling chamber 4. Specifically, under the above configuration, the second inlet 16 is used to connect an external water tank and a second water pump. The second water pump draws water into the second inlet 16, which then enters the second water-cooling pipe 18. The second outlet 17 is used to discharge water into the water tank from the other end of the external water tank, thereby realizing water circulation for water cooling of the second water-cooling component 7. Preferably, each second water-cooling component 7 has multiple second water-cooling pipes 18, which are arranged in multiple layers and interconnected. Under the above configuration, the water cooling effect is improved. The second water-cooling component 7 is used to reduce the ambient air temperature. At the same time, the blower component 8 is used to reduce the air temperature blown into the cooling chamber 4, thereby improving the cooling effect.

[0051] In this embodiment of the application, the middle frame support mechanism 12 includes a base, an annular support fixture 21, a first lifting component and a second lifting component, and guide posts 30 are provided on both sides below the annular support fixture 21.

[0052] The first lifting assembly includes a first lifting plate 22, a first lifting drive 23, and a plurality of first ejector pins 24 arranged around the outer periphery of the upper end face of the first lifting plate 22. The first lifting drive 23 is mounted on the base, and the output end of the first lifting drive 23 is connected to the lower end face of the first lifting plate 22. The annular support fixture 21 is provided with a plurality of first through holes 25 for the first ejector pins 24 to pass through.

[0053] The second lifting assembly includes a second lifting plate 26, a second lifting drive 27, and a plurality of second ejector pins 28 arranged around the outer periphery of the upper end face of the second lifting plate 26. The second lifting drive 27 is mounted on the base, and the output end of the second lifting drive 27 is connected to the lower end face of the second lifting plate 26. The annular support fixture 21 is provided with a plurality of second through holes 29 for the second ejector pins 28 to pass through.

[0054] The first lifting plate 22 is located below the annular support fixture 21, and the second lifting plate 26 is located below the first lifting plate 22. The lower end of the guide post 30 slides through the first lifting plate 22 and the second lifting plate 26 and is then fixedly connected to the base. The first lifting drive component 23 and the second lifting drive component 27 are electrically connected to the control device respectively. The first ejector pin 24 and the second ejector pin 28 are arranged in an alternating manner. The length of the first ejector pin 24 is greater than the length of the second ejector pin 28. The outer periphery of the first lifting plate 22 is provided with multiple clearance grooves 31 to allow the second ejector pin 28 to pass through. Under the action of the clearance grooves 31, the first ejector pin 24 can easily pass through the first lifting plate 22 and then through the second through hole 29.

[0055] The base is provided with a receiving cavity 32, and the first lifting drive 23 and the second lifting drive 27 are arranged side by side in the receiving cavity 32. The second lifting plate 26 is provided with a third through hole for the output end of the first lifting drive 23 to pass through.

[0056] Specifically, under the above configuration, after the external processing equipment injection molds the mobile phone frame, it is transferred to the annular support fixture 21 of the frame support mechanism 12 of the chain conveyor. The annular support fixture 21 is arranged in annular shape and matches the shape of the mobile phone frame. The annular support fixture 21 is hollow to facilitate air circulation.

[0057] When a batch of mid-frame support mechanisms 12 move to the cooling chamber 4, the first lifting component starts working. The first working time threshold of the first lifting component is set, and the first lifting drive component 23 drives the first lifting plate 22 to rise. This causes the first ejector pin 24 to pass through the first through hole 25 and lift the mobile phone mid-frame on the annular support fixture 21 for support, so that the mobile phone mid-frame is suspended above the annular support fixture 21. Furthermore, the lower end face of the annular support fixture 21 is embedded with a first distance sensor 40. When the distance between the first lifting plate 22 and the annular support fixture 21 reaches the preset first distance threshold, the first lifting plate 22 is stopped.

[0058] When the working time of the first lifting component reaches the first working time threshold, the second lifting component is activated. A second working time threshold is set for the second lifting component. The second lifting drive 27 drives the second lifting plate 26 to rise, causing the second pin 28 to pass through the clearance groove 31 and the second through hole 29. A second distance sensor 41 is embedded in the lower end face of the first lifting plate 22. When the distance between the second lifting plate 26 and the first lifting plate 22 reaches the preset second distance threshold, the second lifting plate 26 is stopped. At this time, the height of the second pin 28 is higher than the height of the first pin 24. The second pin 28 lifts and supports the phone frame, and the lower end face of the phone frame detaches from the second pin 28. When the working time of the second lifting component reaches the second working time threshold... When the time threshold is reached, the second lifting drive 27 drives the second lifting plate 26 to descend, and the first lifting component re-supports the mobile phone frame. The first ejector pin 24 continues to support the mobile phone frame. When the working time of the first lifting component reaches the first working time threshold again, the second lifting component is restarted. This cycle continues until the batch of frame support mechanisms 12 moves to the cooling chamber 4 and reaches the preset cooling time threshold, at which point cooling is complete. The second lifting drive 27 drives the second lifting plate 26 to descend and reset, and the first lifting drive 23 drives the first lifting plate 22 to descend and reset. The ring support fixture 21 supports the mobile phone frame, and then the chain conveyor 3 starts to send the frame support mechanism 12 in the cooling chamber 4 out for discharge.

[0059] The upper ends of the first pin 24 and the second pin 28 are respectively provided with adsorption magnets, which can be used to adsorb the middle frame of the mobile phone, ensuring that the middle frame of the mobile phone is not easily loosened and the structure is reliable. Of course, the adsorption magnet is not a necessary technical feature, because in the embodiments of this application, the first pin 24 and the second pin 28 are both arranged in a ring, which has already achieved effective support for the middle frame of the mobile phone.

[0060] Under the above configuration, on the one hand, the first and second lifting components lift the phone frame into the air, reducing the contact between the phone frame and the annular support fixture 21, increasing the contact area between the phone frame and the air, thereby improving the cooling effect and improving production efficiency; on the other hand, the first and second lifting components work alternately, avoiding long-term contact between the lower end surface of the phone frame and the first and second ejector pins 24 and 28, which could cause uneven cooling and result in unevenness in some parts of the phone frame, affecting product quality; in this embodiment, the alternating contact between the first and second ejector pins 24 and 28 with the lower end surface of the phone frame ensures more uniform cooling at all positions on the lower end surface of the phone frame, preventing unevenness caused by uneven cooling.

[0061] In this embodiment, the mid-frame support mechanism 12 further includes a protective cover 33. The base is equipped with a third lifting drive 34, and the output end of the third lifting drive 34 is connected to a third lifting plate 35. The protective cover 33 is movably arranged around the base and the outer periphery of the annular support fixture 21. The lower end of the protective cover 33 is installed on the outer periphery of the upper end face of the third lifting plate 35. The outer wall of the protective cover 33 is provided with a plurality of ventilation slots 36 at equal intervals, and the ventilation slots 36 are arranged vertically. Specifically, the third lifting drive 34 can drive the protective cover 33 to move up and down, so that the protective cover 33 surrounds the outer periphery of the annular support fixture 21, preventing the mobile phone mid-frame on the annular support fixture 21 from falling off, and the structure is reliable. Moreover, the plurality of ventilation slots 36 provided on the outer wall of the protective cover 33 facilitate air circulation and ensure cooling effect.

[0062] In this embodiment, the third lifting drive 34 is installed in the accommodating cavity 32. The first lifting drive 23, the second lifting drive 27, and the third lifting drive 34 are arranged side by side in the accommodating cavity 32. The base includes an upper base 37 and a lower base 38. A plurality of connecting posts 39 are arranged between the upper base 37 and the lower base 38.
