A laser engraving positioning device for metal shell parts

Abstract

A laser engraving positioning device for metal shells includes a positioning platform, a turbine fan, and an air guide channel. The positioning platform has positioning protrusions and a plurality of arrayed through holes, and a first diversion pipe is embedded in the bottom of the positioning platform. The plurality of through holes are connected to the first diversion pipe. The first diversion pipe is connected to one end of the air guide channel. The turbine fan is installed inside the air guide channel, and shafts are provided at both ends of the outer wall of the turbine fan. The air guide channel has corresponding shaft holes. The shafts are inserted into the shaft holes, and one end of the shaft has a rotating lever to control the direction of the turbine fan. The device can fix the shell through the suction hole of the fixture, preventing laser defocusing due to warping during processing. This allows the laser engraving texture to be perfectly realized on the metal shell, solving both the positioning problem and the problem of metal deformation due to heat.

Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, specifically a laser engraving positioning device for metal shell parts. Background Technology

[0002] With the rapid development of electronic products, portable electronic devices such as mobile phones, MP3 players, personal digital assistants, and laptops have become very common. In order to achieve a better appearance and a special feel, more and more portable electronic devices often use laser engraving technology on their exterior parts to create a metallic texture, or to form some decorative patterns or textures.

[0003] Traditional methods, such as CCD or angular positioning, can only solve the positioning problem. After large-area laser engraving, traditional fixtures cause severe deformation of the product due to continuous heating. This deformation will lead to defects during product processing, resulting in a lower yield. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a laser engraving positioning device for metal shell parts, which can effectively solve the problems mentioned in the background art.

[0005] To solve the above problems, the technical solution adopted by this utility model is: a laser engraving positioning device for metal shell parts, including a positioning platform, a turbine fan, and an air guide channel, characterized in that the positioning platform is provided with positioning protrusions and a plurality of arrayed through holes, and a first diversion pipe is embedded in the bottom of the positioning platform; the plurality of through holes are connected to the first diversion pipe; the first diversion pipe is connected to one end of the air guide channel; the turbine fan is installed in the air guide channel, and the outer wall of the turbine fan is provided with shafts at both ends, and the air guide channel is provided with corresponding shaft holes; the shafts are inserted into the shaft holes, and one end of the shaft is provided with a rotating lever, which controls the direction of the turbine fan by rotating the lever.

[0006] As a further preferred embodiment of this utility model, the positioning platform is provided with four top positioning components, which are respectively installed on the side of the positioning platform. Each top positioning component consists of two push rods and a push plate. The side of the top positioning platform is provided with corresponding slide rails. The push rods are sleeved in the slide rails and are slidably connected to the slide rails. A second diversion pipe is provided between the multiple slide rails for communication. The second diversion pipe is connected to the other end of the air guide channel.

[0007] Compared with the prior art, this utility model provides a laser engraving positioning device for metal shell parts, which has the following beneficial effects:

[0008] This device secures the housing through the suction port of the fixture, preventing warping during processing and resulting in poor laser defocusing. This allows the laser-engraved texture to be perfectly applied to the metal housing, solving both the positioning problem and the issue of metal deformation due to heat. Attached Figure Description

[0016] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0017] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0018] In addition, if "and / or" or "and / or" appears in the text, it means three parallel options. For example, "A and / or B" includes option A, option B, or option A and B are satisfied at the same time.

[0019] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0020] Reference Figure 1-6 This utility model provides a laser engraving positioning device for metal shell parts, including a positioning platform 1, a turbine fan 2, and an air guide channel 3. The positioning platform 1 is characterized by positioning protrusions 4 and a plurality of arrayed through holes 5, with a first diversion pipe 6 embedded at the bottom of the positioning platform 1; the plurality of through holes 5 are connected to the first diversion pipe 6; the first diversion pipe 6 is connected to one end of the air guide channel 3; the turbine fan 2 is installed inside the air guide channel 3, and shafts 7 are provided at both ends of the outer wall of the turbine fan 2, with corresponding shaft holes 8 provided in the air guide channel 3; the shafts 7 are inserted into the shaft holes 8, and one end of the shaft 7 is provided with a rotating paddle 9, which controls the direction of the turbine fan 2.

[0021] As a further preferred embodiment of this utility model, the positioning platform 1 is provided with four top positioning components, which are respectively installed on the side of the positioning platform 1. Each top positioning component consists of two push rods 10 and a push plate 11. The side of the positioning platform 1 is provided with a corresponding slide rail 12. The push rod 10 is sleeved in the slide rail 12 and is slidably connected to the slide rail 12. The push rod 10 is sleeved with a sealing ring strip. A second diversion pipe 13 is provided between the multiple slide rails 12 for communication. The second diversion pipe 13 is connected to the other end of the air guide channel 3.

[0022] As a specific embodiment of this utility model: First, the metal shell workpiece 14 is placed on the positioning platform 1, and the positioning protrusion 4 passes through the shell workpiece 14. Then, the turbine fan 2 is started. At this time, the through hole 5 becomes the air inlet, so that the metal shell workpiece 14 is firmly adsorbed on the positioning platform 1. At the same time, the air flows into the slide 12. Due to the internal sealed pressure, the push rod 10 is pushed out. The push plate 11 supports the inner side of the metal shell workpiece 14, further strengthening the fixation. Then, the machine is turned on for laser engraving, so that the metal shell is always kept on a plane until the processing is completed. After the processing is completed, by twisting the rotating lever 9, the turbine fan in the air guide channel 3 is turned 180°, so that the airflow direction is changed and the air in the slide 12 is drawn away. Under the action of pressure, the push rod 10 is retracted. At this time, the through hole 5 becomes the air outlet, so that the metal shell workpiece 14 can be quickly taken out, improving the processing efficiency.
