Abstract
The utility model relates to an automatic thermo press comprising a thermo press body and a thermo press head arranged at the end of the thermo press body. The thermo press head is a ceramic thermo press head, electric heating elements are arranged at the connected portion of the ceramic thermo press head and the thermo press body and the side wall of the ceramic thermo press head is provided with thermal insulation material. The low-heat expansion of the ceramic material is used to meet the flatness requirement of the process and eliminates the effect of flatness of the thermo press head due to thermal deformation even the temperature is up to 450 DEG C. The temperature of the thermo press can be up to 180 DEG C required by the process and the flatness of the thermo press head can be +/- 1 micrometer.
Description
Technical field
The utility model relates to a kind of automatic hot press.
Background technology
Hot press is for the circuit (golden finger) of welded liquid crystal screen, touch-screen, circuit board etc. and the special equipment of lead-out wire (FPC is FPC etc.), thermal head is the critical component of hot press, present hot press thermal head on the market all is to adopt metallic article, because expanding with heat and contract with cold of metal, so its flatness can not reach requirement, can only cover the shortage by the material of silicone band one class.
Existing hot press thermal head all adopts titanium alloy to make, because the welding of golden finger requires high to the flatness (figure below A face) of thermal head, the conducting particles of minimum only has 0.004mm on the market at present, the reason of expanding with heat and contract with cold of metallic article can be less than ± requirement of 0.005mm, bring by silica gel to remedy, otherwise can there be the problem of loose contact in the conductive ion of pressing, be some conductive ion conducting, some not conducting does not reach technical due requirement.
Therefore, reach desired 180 C(of technique in temperature and consider heat radiation, heat transfer loss etc., when the temperature of thermal head itself will arrive 330 C), the flatness of thermal head can also reach ± 1 μ m, when exerting pressure with temperature to product, can make the conductive ion in the middle of the product reach the automatic hot press that uniform temperature and pressure requires, be whole industry in the urgent need to.
The utility model content
Technical purpose of the present utility model is for the deficiencies in the prior art, provides a kind of and solves thermal deformation to the automatic hot press of the impact of the flatness of thermal head.
The technical scheme that realizes the utility model technical purpose is: a kind of automatic hot press, comprise the hot press body and be arranged at the thermal head of described hot press body end, described thermal head is the ceramics injection head, described ceramics injection head and described hot press body junction are provided with heating, and the sidewall of described ceramics injection head is provided with heat-barrier material.
As the further optimization of technique scheme, described heat-barrier material is silica gel.
As the again one-step optimization of technique scheme, described heating is heating wire.
The another step as technique scheme is optimized, and described electric filament disc is around in the inside of described ceramics injection head.
Compared with prior art, the beneficial effect main manifestations of a kind of automatic hot press of the utility model is: with the low-thermal-expansion performance of ceramic material to satisfy technique to the requirement of flatness, even temperature reaches 450 C, solved the impact of thermal deformation on the flatness of thermal head.Make hot press reach desired 180 C(of technique in temperature and consider heat radiation, heat transfer loss etc., when the temperature of thermal head itself will arrive 330 C), the flatness of thermal head can also reach ± 1 μ m, when exerting pressure with temperature to product, can make the middle conductive ion of product reach uniform temperature and pressure requirement.
Description of drawings
Figure 1 shows that the structural representation of a kind of automatic hot press of the utility model.
The specific embodiment
As one of most preferred embodiment of a kind of automatic hot press of the utility model, referring to accompanying drawing 1, it comprises hot press body 1 and is arranged at the thermal head 2 of described hot press body 1 end, described thermal head 2 is the ceramics injection head, described ceramics injection head 2 is provided with heating 3 with described hot press body 1 junction, and the sidewall of described ceramics injection head is provided with heat-barrier material.
Described heat-barrier material is silica gel.
Described heating 3 is heating wire.
Described electric filament disc is around in the inside of described ceramics injection head.
The automatic hot press of present embodiment to satisfy technique to the requirement of flatness, even temperature reaches 450 C, has solved the impact of thermal deformation on the flatness of thermal head with the low-thermal-expansion performance of ceramic material.Make hot press reach desired 180 C(of technique in temperature and consider heat radiation, heat transfer loss etc., when the temperature of thermal head itself will arrive 330 C), the flatness of thermal head can also reach ± 1 μ m, when exerting pressure with temperature to product, can make the middle conductive ion of product reach uniform temperature and pressure requirement.
In sum; after those of ordinary skill in the art reads the utility model file; need not the replacement that scheme between other various corresponding conversion scheme or each embodiment of the utility model is made in creative mental labour according to the technical solution of the utility model and technical conceive, all belong to the scope that the utility model is protected.
