Description

Technical Field

[0001] This application relates to the technical field of sandblasting for mobile phone components, and in particular to an automated production line for sandblasting mobile phone components. Background Technology

[0002] In the field of mobile phone manufacturing, sandblasting of component surfaces is a core link connecting machining with subsequent processes such as anodizing and spraying. It has both functional and decorative value. Especially for structural components such as the mobile phone frame, sandblasting can remove the oxide layer and burrs left by machining through high-speed sand flow impact, while creating a micro-concave-convex structure to achieve a uniform matte effect or specific texture.

[0003] Currently, most sandblasting processes in the industry adopt a semi-automated or manual-assisted mode. The specific process is as follows: First, workers usually use masking tape or masking ink to cover the holes and grooves on the middle frame that do not need to be sandblasted. Then, the parts are manually pushed into the sandblasting chamber one by one for processing. After processing, the parts are unloaded and transferred to the next process by manual labor.

[0004] The sandblasting process for the mobile phone frame, especially the sealing of holes and grooves, requires a lot of manual labor. Each production line needs to be staffed with a large number of workers, and production is easily affected by the skill level and fatigue of the workers, resulting in low production efficiency and difficulty in meeting the requirements of large-scale and high-precision mobile phone manufacturing. Summary of the Invention

[0005] To improve the efficiency of sandblasting mobile phone mid-frames, this application provides an automated production line for sandblasting mobile phone components.

[0006] The automated sandblasting production line for mobile phone components provided in this application adopts the following technical solution: An automated sandblasting production line for mobile phone components includes a masking device, a sandblasting device, a sand removal device, and a material unloading device. The automated sandblasting production line for mobile phone components also includes a transfer device. The masking device includes a worktable on which a masking fixture is placed. The worktable is provided with a support mechanism and an assembly mechanism. The support mechanism is used to fix the mobile phone frame, and the assembly mechanism is used to assemble the masking fixture onto the mobile phone frame.

[0007] By adopting the above technical solution, the following actions can be achieved: First, the phone frame is fixed on the support mechanism; then, the masking fixture is assembled onto the phone frame using the assembly mechanism; next, the phone frame is sequentially transferred to the sandblasting device and the sand removal device using the transfer device, thereby completing the sandblasting and sand removal processes in sequence; finally, the phone frame reaches the unloading device for unloading. This application can improve the efficiency of sandblasting the phone frame.

[0008] Preferably, the shielding fixture includes a mounting block, the end of which is provided with a sealing plate, and the sealing plate is provided with a plurality of sealing heads; the mounting block is also equipped with an elastic clamping mechanism.

[0009] By adopting the above technical solution, the sealing plate can be embedded into the mobile phone frame and multiple sealing heads can be used to block the holes and slots on the mobile phone frame. Then, the elastic clamping mechanism can be used to clamp the mobile phone frame to ensure the reliability of the shielding fixture position.

[0010] Preferably, the elastic clamping mechanism includes a first bevel gear and a plurality of second bevel gears, each second bevel gear meshing with the first bevel gear, the mounting block having a cavity, the first bevel gear and the plurality of second bevel gears being rotatably connected to the cavity; each second bevel gear being connected to a rotating shaft, each rotating shaft being threadedly connected to a connecting seat, and each connecting seat being fitted with a clamping component.

[0011] By adopting the above technical solution, after the sealing plate is embedded into the middle frame of the mobile phone, rotating the first bevel gear can drive multiple second bevel gears to rotate, thereby driving multiple rotating shafts to rotate. The rotation of the rotating shafts will drive the connecting seat to move back and forth, thereby making the clamping component clamp against the middle frame of the mobile phone.

[0012] Preferably, the clamping assembly includes a pressing block, the connecting seat has a connecting rod, the pressing block is slidably connected to the connecting rod, the connecting rod is sleeved with a pressing spring, and the two ends of the pressing spring are respectively connected to the connecting seat and the pressing block.

[0013] By adopting the above technical solution, when the connecting seat moves, the pressing block will also be moved and pressed against the middle frame of the phone. At this time, the pressing spring will provide pressing force to the pressing block and the pressing spring can prevent the pressing block from pressing against the middle frame of the phone with too much force, which would damage the middle frame structure of the phone.

[0014] Preferably, the first bevel gear has a rotating portion that extends beyond the mounting block.

[0015] By adopting the above technical solution, the first bevel gear can be easily rotated by rotating the screwing part.

[0016] Preferably, the bearing mechanism includes a flipping drive unit disposed on the worktable and a bearing platform connected to the flipping drive unit, a clamping drive unit mounted on the bearing platform, and a clamping plate connected to the clamping drive unit; the assembly mechanism includes a robot arm, a suction cup connected to the robot arm, a rotating drive unit also connected to the robot arm, and a turning head connected to the rotating drive unit.

[0017] By adopting the above technical solution, after the clamping plate is clamped by the driving clamping component, the driving robot drives the suction cup to adsorb and place the masking fixture on the mobile phone frame. Then, the rotating drive component drives the rotating head to rotate to complete the assembly of the masking fixture and the mobile phone frame.

[0018] Preferably, each of the sealing heads includes a cone portion at the end away from the sealing plate.

[0019] By adopting the above technical solution, it is easy to insert the plug into the hole or groove.

[0020] Preferably, the sand removal device includes a frame, a belt conveyor mounted on the frame, a sand removal funnel located below the belt conveyor, a collection box located below the sand removal funnel, and a vibrating element mounted on the frame.

[0021] By adopting the above technical solution, after the sandblasted mobile phone frame is transferred to the belt conveyor by the transfer device, the excess sand can be vibrated and dropped through the sand drop funnel into the collection box by the vibrating component.

[0022] In summary, the present invention has at least one of the following beneficial technical effects: 1. This application enables the following actions: First, the phone frame is fixed on the support mechanism; then, the masking fixture is assembled onto the phone frame using the assembly mechanism; next, the phone frame is sequentially transferred to the sandblasting device and the sand removal device using the transfer device, thereby completing the sandblasting and sand removal processes sequentially; finally, the phone frame reaches the unloading device for unloading. This application can improve the efficiency of sandblasting the phone frame; 2. In this application, the sealing plate can be embedded into the middle frame of the mobile phone and the holes and slots on the middle frame of the mobile phone can be blocked by multiple sealing heads. Then, by rotating the first bevel gear, multiple second bevel gears can be driven to rotate, thereby driving multiple rotating shafts to rotate. The rotation of the rotating shafts will drive the connecting seat to move back and forth, so that the clamping component is pressed against the middle frame of the mobile phone, thus ensuring the reliability of the position of the shielding fixture. 3. After the sandblasted mobile phone frame is transferred to the belt conveyor by the transfer device, the excess sand is vibrated off through the sand drop funnel and into the collection box by the vibrating device.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0027] This application discloses an automated production line for sandblasting mobile phone components. It is used to improve the efficiency of sandblasting the mid-frame of mobile phones. In this embodiment, reference is made to... Figure 1 The phone frame is rectangular in shape. One end of the phone frame is the part that needs to be sandblasted, while the other end of the phone frame with the flange, as well as the parts with holes and grooves, do not need to be sandblasted.

[0028] Reference Figure 2 The automated sandblasting production line for mobile phone components includes a shielding device 1, a sandblasting device 2, a sand removal device 3, a material unloading device 4, and a transfer device 5.

[0029] First, the masking device 1 is used to assemble the masking fixture 12 on the mobile phone frame. Then, the transfer device 5 is used to transfer the mobile phone frame to the sandblasting device 2 and the sand removal device 3 in sequence, thereby completing the sandblasting and sand removal in sequence. Finally, the mobile phone frame will be sent to the unloading device 4 by the transfer device 5, so that the unloading device 4 can unload the material.

[0030] Reference Figure 3 The shielding device 1 includes a workbench 11, on which multiple shielding fixtures 12 and multiple mobile phone frames are stacked. The workbench 11 is provided with multiple support mechanisms 13 and multiple assembly mechanisms 14. The support mechanisms 13 are used to fix the mobile phone frames, and the assembly mechanisms 14 are used to assemble the shielding fixtures 12 onto the mobile phone frames. The multiple support mechanisms 13 and multiple assembly mechanisms 14 cooperate with each other.

[0031] Reference Figure 4 The supporting mechanism 13 includes a flipping drive 131 disposed on the worktable 11 and a support platform 132 connected to the flipping drive 131. The support platform 132 has a through slot 1321. The flipping drive 131 is, for example, a flipping cylinder. Two opposing clamping drive members 133 are mounted on the support platform 132. The clamping drive members 133 are, for example, clamping cylinders. Each clamping drive member 133 is connected to a clamping plate 134.

[0032] Reference Figure 5 The assembly mechanism 14 includes a robot arm 141 mounted on the worktable 11, a suction cup 142 connected to the robot arm 141, a drive unit 143 also connected to the robot arm 141, and a screwing head 144 connected to the drive unit 143. The screwing head 144 includes a screwing hole at the end. The drive unit 143 is, for example, a geared motor or a pneumatic motor.

[0033] The driving robot 141 moves the suction cup 142 to pick up the mobile phone frame pre-placed on the worktable 11 and place it on the carrier 132 with the end of the mobile phone frame to be sandblasted facing upwards. The driving two clamping drive units 133 drive the two clamping plates 134 to move towards each other to clamp and fix the mobile phone frame in place for subsequent installation of the masking fixture 12.

[0034] Reference Figure 6 and Figure 7 The shielding fixture 12 includes a mounting block 121, with a sealing plate 122 at one end. The sealing plate 122 has multiple sealing heads 123, which are made of polytetrafluoroethylene (PTFE), a material that is not easily adhered to by sand. Figure 1 The sealing head 123 is used to be inserted into the hole or groove of the mobile phone frame to complete the sealing. In addition, in order to facilitate the insertion of the sealing head 123 into the hole or groove, each sealing head 123 includes a tapered portion at the end away from the sealing plate 122; the mounting block 121 is also equipped with an elastic clamping mechanism 124.

[0035] Reference Figure 6 and Figure 8 Specifically, the elastic clamping mechanism 124 includes a first bevel gear 1241 and four second bevel gears 1242. Each second bevel gear 1242 meshes with the first bevel gear 1241. The axis of the first bevel gear 1241 is perpendicular to the axis of the second bevel gear 1242. The four second bevel gears 1242 are evenly distributed along the circumference of the first bevel gear 1241. The mounting block 121 has a cavity 1211. The first bevel gear 1241 and the multiple second bevel gears 1242 are rotatably connected to the cavity 1211. Each second bevel gear 1242 is connected to a rotating shaft 1243. Each rotating shaft 1243 is threadedly connected to a connecting seat 1244. The end of the connecting seat 1244 is slidably connected to the closing plate 122. Each connecting seat 1244 is equipped with a clamping component 1245. To facilitate the rotation of the first bevel gear 1241, the first bevel gear 1241 has a hexagonal rotating part 1246, which extends outside the mounting block 121.

[0036] Reference Figure 8 Taking one of the clamping components 1245 as an example: the clamping component 1245 includes a pressing block 12451, the connecting seat 1244 has a connecting rod 12452, the pressing block 12451 is slidably connected to the connecting rod 12452, the connecting rod 12452 is sleeved with a pressing spring 12453, and the two ends of the pressing spring 12453 are respectively connected to the connecting seat 1244 and the pressing block 12451.

[0037] The drive unit 131 rotates the carrier platform 132 so that the end of the phone frame that does not need sandblasting faces upwards. The drive unit 141 and suction cup 142 grasp the masking fixture 12 and move it onto the phone frame. At this time, it is necessary to ensure that the sealing plate 122 is embedded into the phone frame. Then, the drive unit 141 moves the screwing head 144 until the screwing part 1246 is inserted into the screwing hole. The drive unit 143 drives the screwing part 1246 to rotate, thereby driving the first bevel gear 1241 to rotate. The four second bevel gears 1242 rotate, which drives the rotating shaft 1243 to rotate, thereby causing the connecting seat 1244 to move away from the second bevel gears 1242. The movement of the connecting seat 1244 causes the pressing block 12451 to press against the inner wall of the phone frame. The pressing spring 12453 provides a pressing force to the pressing block 12451. Based on the pressing of the four pressing blocks 12451 against the phone frame, the shielding fixture 12 can be reliably fixed on the phone frame to complete the shielding.

[0038] Reference Figure 9 and Figure 10 and combined Figure 2 The transfer device 5 includes multiple gripping components 51 and material transfer components 52 located between adjacent processes. Taking any one gripping component 51 as an example: the gripping component 51 includes a robotic arm 511, a gripper cylinder 512 connected to the robotic arm 511, and a clamping plate 513 connected to the gripper cylinder 512. In this embodiment, there are four gripper cylinders 512 and four clamping plates 513, which are circumferentially distributed. Taking any one of the material transfer components 52 as an example: the material transfer component 52 includes a belt conveyor 521 and a tray 522 disposed on the belt conveyor 521. The specific structure of the belt conveyor 521 is prior art and will not be described in detail here.

[0039] Reference Figure 11 The sandblasting device 2 is, for example, a top-spray gun type rotary automatic sandblasting machine or a motion contour multi-station automatic sandblasting machine. The sandblasting device 2 has an inlet 21 and an outlet 22. Sandblasting can be completed by placing the mobile phone frame into the conveyor automatic sandblasting machine through the inlet 21 and removing it from the outlet 22. It can usually achieve sandblasting of the mobile phone frame to be sandblasted from top to bottom. The specific structure of the sandblasting device 2 is existing technology and will not be described in detail here.

[0040] Reference Figure 12The sand removal device 3 includes a frame 31, a belt conveyor 32 mounted on the frame 31, a sand removal funnel 33 located below the belt conveyor 32, a collection box 34 located below the sand removal funnel 33, and a vibrating element 35 mounted on the frame 31. The collection box 34 can be pulled off, and the vibrating element 35 is, for example, a vibrating motor. In order to prevent the mobile phone frame from falling, two limiting plates 36 for limiting the mobile phone frame are installed on the belt conveyor 32. The two limiting plates 36 are arranged in parallel, and the mobile phone frame can pass between the two limiting plates 36.

[0041] Reference Figure 9 and Figure 2 The feeding device 4 and the gripping component 51 have the same structure, so they will not be described in detail here.

[0042] The implementation principle of the automated sandblasting production line for mobile phone components in this embodiment is as follows: The robotic arm 141 drives the suction cup 142 to move and grab the mobile phone frame pre-placed on the worktable 11 and place it on the carrier 132. The end of the mobile phone frame to be sandblasted faces upward. The two clamping drive components 133 drive the two clamping plates 134 to move towards each other to clamp and fix the mobile phone frame. The drive unit 131 rotates the carrier platform 132 so that the end of the phone frame that does not need sandblasting faces upwards. The drive robot 141 and suction cup 142 grasp the masking fixture 12 and move it through the through groove 1321 to place it onto the phone frame. At this time, it is necessary to ensure that the sealing plate 122 is embedded in the phone frame. Then, the drive robot 141 moves the screwing head 144 until the screwing part 1246 is inserted into the screwing hole. The drive unit 143 drives the screwing part 1246 to rotate, thereby driving the first bevel gear 1241. The rotation drives the four second bevel gears 1242 to rotate. The rotation of the second bevel gears 1242 drives the rotating shaft 1243 to rotate, thereby causing the connecting seat 1244 to move away from the second bevel gears 1242. The movement of the connecting seat 1244 causes the pressing block 12451 to press against the inner wall of the mobile phone frame. The pressing spring 12453 provides a pressing force for the pressing block 12451. Based on the pressing of the four pressing blocks 12451 against the mobile phone frame, the shielding fixture 12 can be reliably fixed on the mobile phone frame. The drive flipping drive 131 drives the carrier platform 132 to flip, and drives the two clamping drive 133 to move the two clamping plates 134 apart to release the clamping of the mobile phone frame. The mobile phone frame is transferred to the sandblasting device 2 by the transfer device 5 for sandblasting. After the sandblasting is completed, the mobile phone frame is transferred to the belt conveyor 32 by the transfer device 5. The belt conveyor 32 drives the mobile phone frame to move and drives the vibration device 35 to make the excess sand fall into the collection box 34. The mobile phone frame can then be unloaded by the unloading device 4.

[0043] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
