Description

Technical Field

[0001] This utility model belongs to the technical field of mobile phone processing equipment, and in particular relates to a device for removing burrs from a mid-frame. Background Technology

[0002] Mobile phone frame burr removal technology refers to the technique of removing burrs and flash from the mid-frame during the mobile phone manufacturing process, especially after CNC machining. If these burrs and flash are not properly removed, they will affect the appearance quality of the mobile phone and the user's feel.

[0003] Recent technological advancements include the use of dry ice removal, a highly efficient and environmentally friendly method. Dry ice removal utilizes the low temperature and high-speed impact of dry ice particles to instantly freeze and dislodge burrs and sharp edges, achieving the desired removal effect. This method does not cause physical damage or chemical corrosion to the product surface, and no harmful substances are generated during the process.

[0004] However, dry ice removal is a consumable processing method. After use, dry ice dissipates into the environment, resulting in consumption and increasing the cost of burr removal. At the same time, dry ice is affected by environmental factors. When the ambient temperature is slightly high, the dry ice state is unstable and sublimates prematurely, which can easily result in air being blown onto the burrs on the frame, making it impossible to remove the burrs. Therefore, dry ice removal has defects such as instability and high cost, which urgently need to be improved. Utility Model Content

The following description is based on the accompanying drawings. Figures 1-7 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

Therefore, they should not be construed as limitations on this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0038] In one embodiment of this utility model, such as Figures 1-7 As shown, a mid-frame burr removal device is provided, including a base 100, a frame 200, a feeding mechanism 300, a multi-axis positioning mechanism 400, and a sandblasting mechanism 500. The frame 200 is disposed on the base 100; the feeding mechanism 300 is disposed on the base 100 and is used to transport the mid-frame of the mobile phone; the multi-axis positioning mechanism 400 is disposed on the base 100 and is located inside the frame 200; the sandblasting mechanism 500 is disposed on the multi-axis positioning mechanism 400; wherein, the feeding mechanism 300 includes a linear module 310 and an angle adjustment component 320, the conveying path of the linear module 310 extends to below the output end of the multi-axis positioning mechanism 400, the angle adjustment component 320 is disposed at the output end of the linear module 310, and the angle adjustment component 320 is used to adjust the mid-frame of the mobile phone to a preset angle orientation, so that the high-speed airflow and nylon sand output by the sandblasting mechanism 500 can contact the burrs at a preset position on the mid-frame of the mobile phone.

[0039] Specifically, the operator places the burr-covered mobile phone frame to be processed on the angle adjustment component 320. The linear module 310 drives the angle adjustment component 320 to move to the output end of the multi-axis positioning mechanism 400. The angle adjustment component 320 drives the mobile phone frame to rotate to a preset angle. The multi-axis positioning mechanism 400 drives the sandblasting mechanism 500 to move to a preset position, aligning the output end of the sandblasting mechanism with the burr generation position of the mobile phone frame to be processed. The sandblasting mechanism 500 sprays a mixture of high-speed airflow and nylon sand onto the burr, thereby removing the burr. Compared with the existing technology of using dry ice to remove burrs from mobile phone frames, which has the technical problems of unstable removal effect and high burr removal cost, the burr removal device for the frame provided by this utility model uses high-speed airflow carrying nylon sand to impact the burr, effectively removing the burr. At the same time, the nylon sand can be recycled and reused after impact, saving consumables. Moreover, the state of the nylon sand is not affected by temperature, effectively ensuring the stability of the burr removal process each time.

[0040] like Figures 1-7 As shown, a conical funnel 110 is further provided inside the base 100. The edge of the conical funnel 110 is connected to the bottom edge of the frame 200, so that the nylon sand output by the sandblasting mechanism 500 flows back to the center of the conical funnel 110 after touching the inner wall of the frame 200. The output end of the conical funnel 110 is connected to a recycling filter mechanism pipe.

[0041] In this embodiment, the output end of the conical funnel 110 is provided with a filter screen. The filter screen has pores that allow burrs and nylon sand that have fallen off the mobile phone frame to pass through. Large, blocky burrs cannot pass through the filter pores, which helps to improve the efficiency of nylon sand recovery.

[0042] like Figures 1-7 As shown, further, the output end of the recycling filter mechanism is connected to the input end of the sandblasting mechanism 500 via a pipe and is used to transport the filtered nylon sand to the sandblasting mechanism 500. In this embodiment, the recycling filtration mechanism includes a negative pressure component, an output component, and filter paper. The negative pressure component is connected to the output end pipe of the conical funnel 110. The filter paper is used to filter the nylon sand and burr debris sucked in by the negative pressure component, separating the burr debris from the nylon sand. The output component is used to transport the filtered nylon sand to the sandblasting mechanism 500. Using a recycling filtration mechanism to centrally recycle nylon sand is beneficial to further improve the utilization rate of nylon sand. The filtration function in the recycling filtration mechanism can purify the nylon sand to reduce the burr content moving into the sandblasting mechanism 500. It is worth noting that the volume of burr detached from the mobile phone frame is not fixed. The filter paper is used to block large-volume burrs from entering the sandblasting mechanism 500 to prevent large-volume burrs from getting stuck in the sandblasting mechanism 500, ensuring that the recycling filtration mechanism can smoothly replenish nylon sand to the sandblasting mechanism 500.

[0043] like Figures 1-7 As shown, furthermore, the input end of the sandblasting mechanism 500 is also connected to a blower mechanism, which is used to drive a high-speed airflow into the sandblasting mechanism 500. In this embodiment, the blower mechanism is provided with a filter grid, which is used to filter impurities in the air to prevent dust and particulate matter in the air from contaminating the mobile phone frame.

[0044] like Figures 1-7 As shown, the sandblasting mechanism 500 further includes an air inlet pipe 510, a sand inlet pipe 520, a mixing pipe 530, and an output pipe 540. The output pipe 540 is disposed at the output end of the multi-axis positioning mechanism 400, the mixing pipe 530 is disposed at the input end of the output pipe 540, the air inlet pipe 510 is disposed at the input end of the mixing pipe 530, the output end of the sand inlet pipe 520 is connected to the connection point of the air inlet pipe 510 and the mixing pipe 530, the air inlet pipe 510 is connected to the output end of the blower mechanism, and the sand inlet pipe 520 is connected to the output end of the recycling filter mechanism.

[0045] In another embodiment of this utility model, the air inlet pipe 510 and the sand inlet pipe 520 are symmetrically distributed along the extension path of the mixing pipe 530; wherein, a control unit is provided between the air inlet pipe 510, the sand inlet pipe 520 and the mixing pipe 530, the control unit is a solenoid valve, the control unit has two sets of input terminals, the two sets of input terminals are respectively connected to the air inlet pipe 510 and the sand inlet pipe 520, and the output terminal of the control unit is connected to the mixing pipe 530. The control unit is used to control the flow rate of the air inlet pipe 510 and the sand inlet pipe 520, thereby adjusting the impact strength required for different models of mobile phone frames to improve the adaptability of the frame burr removal device.

[0046] Furthermore, the air inlet pipe 510 and the mixing pipe 530 are connected sequentially along a straight line, and the sand inlet pipe 520 is staggered with the mixing pipe 530 and the air inlet pipe 510. In this embodiment, after the air inlet pipe 510 and the mixing pipe 530 are connected sequentially, the control unit can be set at the input end of the air inlet pipe 510. Since the air inlet pipe 510 and the mixing pipe 530 are arranged sequentially along the same straight path, the airflow of the air inlet pipe 510 produces a siphon effect on the nylon sand in the sand inlet pipe 520. The greater the airflow, the greater the flow rate of the air inlet pipe 510. By controlling only the flow rate of the air inlet pipe 510, the nylon sand content in the mixing pipe 530 can be adjusted, thereby enabling the sandblasting mechanism 500 to achieve a targeted sandblasting effect.

[0047] like Figures 1-7As shown, the multi-axis positioning mechanism 400 further includes a mounting frame 410, an X-axis moving module 420, and a Z-axis moving module 430. The mounting frame 410 is disposed on the base 100, the X-axis moving module 420 is disposed at the top of the mounting frame 410, the Z-axis moving module 430 is disposed at the output end of the X-axis moving module 420, and the sandblasting mechanism 500 is disposed at the output end of the Z-axis moving module 430. In this embodiment, the drive paths of the X-axis moving module 420, the Z-axis moving module 430, and the linear module 310 are arranged perpendicularly to each other. The X-axis moving module 420, the Z-axis moving module 430, and the linear module 310 form a CNC positioning module, which is programmed and controlled by a CNC system to effectively realize the precise movement of the sandblasting mechanism 500 to adapt to the burr removal requirements of different mobile phone frame models.

[0048] like Figures 1-7 As shown, the angle adjustment component 320 further includes a movable base 321, a rotating component 322, and a rotating plate 323. The movable base 321 is disposed on the linear module 310, the rotating component 322 is disposed at the end of the movable base 321, one end of the rotating plate 323 is rotatably connected to the end of the movable base 321, the output end of the rotating component 322 is drivenly connected to the other end of the rotating plate 323, and the rotating plate 323 is provided with a clamping mold for limiting the mobile phone frame.

[0049] In this embodiment, the clamping module includes a lower mold and an upper mold. The lower mold is fixedly mounted on the rotating plate 323, and the upper mold is detachably connected to the lower mold. The upper mold and the lower mold have grooves at their opposite ends for accommodating the mobile phone frame. The upper mold and the lower mold are detachably positioned and connected by a pin. The upper mold has a through hole for aligning with the burr forming position of the mobile phone frame, so that high-speed nylon sand can enter and contact the burr on the mobile phone frame.

[0050] like Figures 1-7 As shown, further, the frame 200 is located near the end feed port 210 of the linear module 310. A lifting door 211 is provided inside the feed port 210. A grating detection unit is provided on the lifting door 211 to prevent the lifting door 211 from pinching a hand. A loading robot for conveying the mobile phone mid-frame to be processed is provided on one side of the feed port 210, which can realize fully automatic mobile phone mid-frame loading operation and improve production efficiency.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
