Description

Technical Field

[0001] This invention relates to the field of mobile phone frame processing, specifically to the field of laser engraving and wire drawing for mobile phone frames. Background Technology

[0002] Mobile phone frames are typically made of metal. To enhance aesthetics and improve user experience, the outer surface of the frame is usually laser-engraved to create a brushed finish. Currently, this is generally achieved using laser engraving equipment.

[0003] Because the mobile phone frame is a ring-shaped structure with a rectangular cross-section, and because the surface to be laser-etched is preferably horizontal during laser engraving, automated laser engraving of the mobile phone frame requires a robotic arm in conjunction with a specialized fixture. This fixture grips the frame and pulls it below the laser emitter, ensuring that each of the four outer surfaces of the frame is horizontally positioned below the laser emitter before the laser engraving operation. This existing laser engraving method has several drawbacks. Specifically, the robotic arm needs to perform the following actions: the fixture grips the mobile phone frame lying flat on the conveyor line; the fixture flips, aligning one outer surface of the frame horizontally below the laser emitter; after laser engraving, the fixture is pulled above the conveyor line; the fixture flips again, aligning the frame flat; the fixture releases, and the frame falls onto the conveyor line and is pulled away. These actions must be performed sequentially, with delays between adjacent actions, resulting in relatively low efficiency and making it unsuitable for automated production.

[0004] Based on the above, the present invention proposes a laser engraving and wire drawing device. Summary of the Invention

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] In the attached diagram of this solution, 'a' refers to the phone's mid-frame.

[0021] Reference Figures 1-9 A laser engraving and wire drawing device includes a frame 100, on which a laser emitting end 101, a conveyor line 102 and a mounting bracket 103 are provided. A clamping component 200 is provided on the mounting bracket 103, wherein the clamping component 200 is located above the conveyor line 102 and the laser emitting end 101 is located above the clamping component 200.

[0022] The laser emitter 101 and the conveyor line 102 can both be implemented using existing technologies, so they will not be described in detail. One of the core aspects of this case is the clamp component 200.

[0023] The clamping component 200 includes a clamping assembly, a rotating assembly, and a stripping auxiliary assembly.

[0024] Reference Figures 7-9 The clamp assembly includes a fixed shaft 212 fixedly mounted on the mounting bracket 103, the axis of the fixed shaft 212 being parallel to the conveying direction of the conveyor line 102.

[0025] A rotating cylindrical shell 213 is sleeved on the outside of the fixed shaft 212. Furthermore, one end of the rotating cylindrical shell 213 is closed and has a sleeve hole coaxially provided, while the other end is open and has a shell cover. The rotating cylindrical shell 213 is movably sleeved on the outside of the fixed shaft 212 through the sleeve hole.

[0026] The outer circular surface of the rotating cylindrical shell 213 is provided with guide holes in the radial direction, and two guide holes are arranged in an array along the circumference of the rotating cylindrical shell 213.

[0027] There is a slide rod 217 inside the rotating cylindrical shell 213. Each of the two sides of the slide rod 217 extends vertically along the width direction and has a drive support rod 218. The ends of the two drive support rods 218 pass through two guide holes respectively, and the drive support rods 218 and the guide holes form a sliding guide engagement.

[0028] The slide rod 217 is provided with a linkage hole 219, the guiding direction of the linkage hole 219 is parallel to the length direction of the slide rod 217, and the end of the fixed shaft 212 is eccentrically provided with a linkage pin 220, which forms a sliding guide fit with the linkage hole 219.

[0029] When the rotating cylinder shell 213 rotates, since the fixed shaft 212 remains stationary, the drive rod 218 can move within the guide hole under the cooperation of the connecting pin 220 and the connecting hole 219. That is, when the rotating cylinder shell 213 rotates, the drive rod 218 moves within the guide hole and also rotates with the rotating cylinder shell 213.

[0030] The fixture assembly also includes two fixture units 216 arranged in an array along the circumferential direction of the fixed axis 212.

[0031] The clamping unit 216 includes a side support rod 2161 that is fixedly disposed radially on the outer circular surface of the rotating cylinder shell 213, and the extension direction of the side support rod 2161 is parallel to the movement direction of the drive support rod 218.

[0032] The end of the side support rod 2161 is hinged to a mounting support rod 2162, and a connecting support rod 2163 is hinged between the mounting support rod 2162 and the drive support rod 218. Furthermore, the hinge shafts formed at the hinge points of the side support rod 2161 and the mounting support rod 2162, the hinge shafts formed at the hinge points of the mounting support rod 2162 and the connecting support rod 2163, and the hinge shafts formed at the hinge points of the drive support rod 218 and the connecting support rod 2163 are all parallel to the guiding direction of the linkage hole 219.

[0033] Initially, one clamping unit 216 is located directly above the rotating cylinder shell 213 and the mounting rod 2162 of this clamping unit 216 is parallel to the fixed axis 212, and the other clamping unit 216 is located directly below the rotating cylinder shell 213 and the mounting rod 2162 of this clamping unit 216 is arranged vertically.

[0034] The rotation of the rotating cylinder shell 213 will cause the clamping unit 216 to rotate together. At the same time, since the drive rod 218 moves in the guide hole, one drive rod 218 will push the connecting rod 2163 of the corresponding clamping unit 216 outward, and the other drive rod 218 will pull the connecting rod 2163 of the corresponding clamping unit 216 inward. When the rotating cylinder shell 213 rotates 180 degrees and the two clamping units exchange positions, the states of the two clamping units will also be exchanged.

[0035] Furthermore, a cylinder 2164 is provided on the mounting rod 2162. The extension and retraction direction of the cylinder 2164 is parallel to the extension direction of the mounting rod 2162. The cylinder 2164 is a technology that can be implemented in the prior art and will not be described in detail. A side clamping plate 2165 is rotatably mounted at the end of the cylinder 2164, for example, by means of a bearing. The large surface of the side clamping plate 2165 is perpendicular to the extension and retraction direction of the cylinder 2164. The large surface refers to the side with the largest area of ​​the side clamping plate 2165. An elastic layer, for example, made of rubber or silicone, is provided on the outer surface of the side clamping plate 2165.

[0036] Reference Figure 6 The rotating assembly includes a side bracket 204 slidably mounted on the mounting bracket 103 and a spring 205 disposed between the two. The moving direction of the side bracket 204 is parallel to the conveying direction of the conveyor line 102, and the spring 205 is located on the side of the side bracket 204 away from the clamping assembly.

[0037] A servo motor 206 is mounted on the side bracket 204. The output end of the servo motor 206 is connected to a transmission shaft 207. The transmission shaft 207 is coaxial with the fixed shaft 212. A protrusion 208 is provided at the end of the transmission shaft 207. A connecting shaft 214 is coaxially mounted on the end face of the cover. A groove 215 is provided at the end of the connecting shaft 214. Furthermore, the ends of the transmission shaft 207 and the connecting shaft 214 are arranged facing each other. Initially, the protrusion 208 is inserted into the groove 215.

[0038] A rotating shaft 210 is also installed on the side bracket 204. The rotating shaft 210 is located above the transmission shaft 207. The rotating shaft 210 and the transmission shaft 207 are parallel to each other. The rotating shaft 210 and the transmission shaft 207 are connected by a power transmission component 209.

[0039] A side pressure plate 211 is provided at one end of the rotating shaft 210 facing the clamping assembly. Furthermore, initially, the center line of the cylinder 2164 of the clamping unit 216 located above the rotating cylinder shell 213 is on the same straight line as the axis of the rotating shaft 210.

[0040] Reference Figure 6 The unloading auxiliary assembly includes a movable support 202 and a linear module 201 for driving the movable support 202 to move. The moving direction of the movable support 202 is parallel to the conveying direction of the conveyor line 102.

[0041] The bottom of the movable support 202 extends into a limiting rod 203. The extension direction of the limiting rod 203 is parallel to the moving direction of the movable support 202. There are two limiting rods 203, and the distance between the two limiting rods 203 is arranged horizontally and perpendicular to the extension direction of the limiting rod 203.

[0042] The upper surface of the mobile phone frame, which is clamped by the clamping unit 216 located below the rotating cylinder shell 213, is lower than the lower surface of the limiting rod 203. That is, during the process of the movable bracket 202 being moved by the linear module 201, the limiting rod 203 can be located above the mobile phone frame and the two limiting rods 203 are respectively located on both sides of the side plate 2165. At this time, the cylinder 2164 retracts, and since the mobile phone frame is restricted from moving upward, the mobile phone frame can be pulled off the side plate 2165.

[0043] Working principle of the invention: Step 1: Refer to Figure 2 The mobile phone frame on the clamping unit 216 above the rotating cylindrical shell 213 is arranged facing the side pressure plate 211, and the mobile phone frame on the clamping unit 216 below the rotating cylindrical shell 213 has been laser engraved. Step Two: Refer to Figure 3 and Figure 5 The clamping unit 216 located above the rotating cylinder 213 has a cylinder 2164 that extends, causing the phone frame to contact the side pressure plate 211 and causing the side bracket 204 to retract. The spring 205 is compressed, and the transmission shaft 207 is disconnected from the connecting shaft 214. Laser engraving is then performed on the upper side of the phone frame via the laser emitter 101. After completion, the servo motor 206 drives the rotating shaft 210 to rotate 90 degrees, and the laser emitter 101 performs laser engraving on the next side of the phone frame. This process is repeated to achieve laser engraving on all four sides of the phone frame. Meanwhile, the clamping unit 216 located below the rotating cylinder shell 213: the linear module 201 drives the limiting rod 203 to move above the mobile phone frame, the cylinder 2164 retracts, and pulls the side clamping plate 2165 out of the mobile phone frame. The laser-engraved mobile phone frame falls onto the conveyor line 102. The conveyor line 102 pulls the laser-engraved mobile phone frame away and pulls the next mobile phone frame to be laser-engraved to be located directly below the side clamping plate 2165. Then, the linear module 201 drives the limiting rod 203 to retract, the cylinder 2164 extends, and inserts the side clamping plate 2165 into the mobile phone frame. It should be noted that the size of the side clamping plate 2165 is slightly smaller than the internal size of the mobile phone frame, and the external size of the elastic layer is slightly larger than the internal size of the mobile phone frame. Therefore, the elastic layer will undergo elastic deformation and be inserted into the mobile phone frame, realizing the connection between the mobile phone frame and the side clamping plate 2165. Step 3: Refer to Figure 4 After the laser engraving of the mobile phone frame is completed, the clamping unit 216 located above the rotating cylinder shell 213: the cylinder 2164 retracts, the spring 205 releases its elastic force, the protrusion 208 re-inserts into the groove 215, the transmission shaft 207 and the connecting shaft 214 resume power connection, and then the servo motor 206 drives the connecting shaft 214 to rotate 180 degrees, so that the two clamping units 216 interchange positions; At this time, the mobile phone frame on the clamping unit 216 above the rotating cylindrical shell 213 is arranged facing the side pressure plate 211, and the mobile phone frame on the clamping unit 216 below the rotating cylindrical shell 213 has been laser engraved. This process is repeated to achieve automated laser engraving of the phone's mid-frame.

[0044] Its technological advantages lie in: Technical effect 1: In this case, there are two clamping units, and the two clamping units can be interchanged in position and state through a linkage structure composed of sliding rods, drive support rods, etc., thereby realizing alternating laser engraving and significantly improving the overall laser engraving efficiency. Technical Effect 2: In this case, the linkage structure composed of components such as sliding rods and drive support rods can clamp the mobile phone frame on the conveyor line. During the interchange of the positions of the two clamping units, the mobile phone frame can be flipped, changing the mobile phone frame from a horizontal arrangement to a vertical arrangement, which further improves the efficiency of laser engraving. In addition, the entire linkage structure is simplified, reducing the complexity of the equipment.
