Description

Technical Field

[0001] The utility model belongs to the technical field of radio frequency tag production equipment, and particularly relates to a laser processing platform for PET antennas. Background Art

[0002] The manufacturing methods of RFID tag antennas mainly include: etching method and laser process. The laser process has the advantage of environmental protection, but the laser process has relatively high requirements for material selection.

[0003] At present, the main substrate of RFID tags is PET. When producing RFID antennas, the graphics are relatively complex and require long-time laser processing on the same plane. PET material is a transparent material, and it is difficult to produce RFID tags with PET as the substrate by laser. When using an ordinary metal platform, the quality is poor. When producing RFID tags with PET as the substrate by laser, after cutting the aluminum foil, the laser will directly penetrate the PET and act on the metal platform, and a large amount of heat energy will be instantly accumulated on the platform, resulting in the melting of the PET. Therefore, the current processing platform cannot process and produce PET antennas for a long time, and there is a problem that the PET antennas are easily melted. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a laser processing platform for PET antennas to solve the problem of difficult processing of PET antennas.

[0009] Compared with the prior art, the above technical solution has the following beneficial effects:

[0010] By providing a receiving cavity on the machine table, a light-transmitting support plate is hermetically arranged at the top opening of the receiving cavity. The light-transmitting support plate can transmit the excess laser to the greatest extent and will not absorb a large amount of laser energy, avoiding damage to the product caused by the melting of the pet antenna due to a large amount of heat generated by the platform absorbing heat.

[0014] In one embodiment, a receiving box for placing the separator is disposed at the inner bottom of the accommodating cavity.

[0015] In one embodiment, handles are provided at the tops of both sides of the receiving box.

[0016] By providing handles on the receiving box, when the separator is placed in the receiving box and the light-transmitting tray is moved away, it is convenient to take and place the separator.

[0017] In one embodiment, a pull-out groove communicating with the accommodating cavity is disposed at one side of the bottom of the accommodating cavity, and a handle is provided at one side of the receiving box close to the pull-out groove.

[0018] By providing a pull-out groove at the bottom of the accommodating cavity, the receiving box can be directly pulled out from the side, and then the separator can be taken out, making the extraction and placement more convenient.

[0023] In one embodiment, handles are provided on both sides of the fixing frame and are embedded in the machine platform. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0036] As shown Figures 1-3 in the figure, a laser processing platform for a PET antenna provided by the present utility model includes: a machine table 1, a light-transmitting support plate 3, and an adsorption pipeline 5.

[0037] A receiving cavity 2 is arranged in the machine table 1, and the receiving cavity 2 is embedded from the surface of the machine table 1. The light-transmitting support plate 3 is hermetically arranged at the top opening of the receiving cavity 2. A plurality of adsorption holes 4 are formed in the light-transmitting support plate 3. The surface of the light-transmitting support plate 3 is basically at the same horizontal plane as the surface of the machine table 1. Above the light-transmitting support plate 3, there is a laser device for processing the PET material antenna.

[0038] One end of the adsorption pipeline 5 is communicated with the receiving cavity 2, and the other end is connected to an external negative pressure air source. Negative pressure is provided through the external air source to adsorb the processing material located on the light-transmitting support plate 3 onto the light-transmitting support plate 3 to maintain stability.

[0039] By arranging the receiving cavity 2 on the machine table 1, and hermetically arranging the light-transmitting support plate 3 at the top opening of the receiving cavity 2, the light-transmitting support plate 3 can transmit the excessive laser to the greatest extent and will not absorb a large amount of laser energy, avoiding damage to the product caused by the melting of the PET antenna due to a large amount of heat generated by the platform absorbing heat.

[0040] Since the support plate at the opening of the receiving cavity 2 is set as the light-transmitting support plate 3, the vast majority of the laser passes through the support plate and enters the bottom of the receiving cavity 2. To ensure that the equipment below is not damaged, an isolation member 6 for blocking the laser is provided. The isolation member 6 is arranged at the bottom of the receiving cavity 2, and the isolation member 6 mainly plays a role in isolating the laser.

[0041] The isolation member 6 arranged at the bottom of the receiving cavity 2 can isolate the laser passing through the light-transmitting support plate 3 and avoid damage to the equipment below and the like caused by the laser.

[0042] Specifically, regarding the selection of the material of the isolation member 6, a material with a high laser isolation rate is mainly selected. In this embodiment, the isolation member 6 is a frosted ceramic isolation member 6, and specifically, alumina ceramic with a low laser absorption rate is used, etc.

[0043] Regarding the specific form of the isolation member 6, an integral plate-like member can be selected or various ways such as particle laying can be adopted, as long as a certain thickness is achieved. In this embodiment, the isolation member 6 is isolation particles or an isolation plate laid at the bottom of the receiving cavity 2.

[0044] To facilitate the taking of the isolation member 6, a receiving box 7 for placing the isolation member 6 is arranged at the inner bottom of the receiving cavity 2. The receiving box 7 is attached to the inner wall of the receiving cavity 2, and the isolation member 6 is accommodated in the receiving box 7 without gaps.

[0045] When the separator 6 is laid at the bottom of the accommodating cavity 3 in an incomplete granular form, the provision of the accommodating box 7 can better carry the separator 6. After placing the granular separator in the accommodating box 7, it is placed in the accommodating cavity 3 through the accommodating box 7, which facilitates the taking and placing of the separator 6.

[0046] In one embodiment, as Figure 1 shown, handles 8 are provided at the top of both sides of the accommodating box 7. By providing the handles 8 on the accommodating box 7, when the separator 6 is placed in the accommodating box 7, when taking and replacing the separator 6, after first moving the light-transmitting support plate 3 away, then it is convenient to take and place the separator 6 through the handles 8.

[0047] In another embodiment, as Figure 3 shown, a pull-out slot 9 communicating with the accommodating cavity 2 is provided on one side of the bottom of the accommodating cavity 2. The bottom of the pull-out slot 9 is smoothly connected to the bottom of the accommodating cavity 2. The diameter of the pull-out slot 9 matches the longitudinal section of the accommodating box 7. A handle 8 is provided on one side of the accommodating box 7 close to the pull-out slot 9. By providing the pull-out slot 9 at the bottom of the accommodating cavity 2, the accommodating box 7 can be directly pulled out from the side, and then the separator 6 can be taken out. The extraction and placement are more convenient, and at this time, there is no need to carry the light-transmitting support plate 3 above the accommodating cavity 2.

[0048] In order to play a better role in protecting and fixing the light-transmitting support plate 3, the periphery of the light-transmitting support plate 3 is covered with a fixing frame 10. The fixing frame 10 can be made of materials such as metal. A step 13 matching the fixing frame 10 is formed at the opening of the top of the accommodating cavity 2. After the fixing frame 10 covers the periphery of the light-transmitting support plate 3, it is fitted and embedded in the step 13. The fixing frame 10 surrounds the light-transmitting support plate 3 to play a protective role and at the same time avoid being scratched by the edge of the light-transmitting support plate 3, and the step 13 can well support the light-transmitting support plate 3.

[0049] As Figure 2 shown, in order to facilitate the handling of the light-transmitting support plate 3, lifting handles 11 are provided on both sides of the fixing frame 10 and are embedded in the machine table 1. By lifting the fixing frame 10 through the lifting handles 11, the light-transmitting support plate 3 is toggled. And the lifting handles 11 are hinged to both ends of the fixing frame 10. Handle slots 12 for embedding the lifting handles 11 are provided at the corresponding positions of the machine table 1 to ensure the flatness of the surface of the machine table 1.

[0050] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
