Description

Technical Field [0001] The present invention relates to a vacuum thermoforming apparatus for a hemispherical touch sensor panel,

The present invention relates to a vacuum thermoforming apparatus for a hemispherical touch sensor panel, and more particularly, to a vacuum thermoforming apparatus for a hemispherical touch sensor panel for forming a hemispherical touch sensor panel.

2. Description of the Related Art In general, a touch sensor panel is an input device for inputting a user's command by converting a contact position, which is in contact with a human hand or an object, into an electrical signal, .

Such a touch sensor panel has been developed to perform various touch functions according to the motions of human fingers or objects. In recent years, particularly, a touch sensor panel has been developed in which a part of the touch sensor panel has a curvature Is being commercialized.

However, in the conventional touch sensor panel, there are many inconveniences in using the touch sensor panel because the entirety of the touch sensor panel can not have a shape having a curvature.

For example, in recent years, as the market of smart cars has expanded in the automobile field, studies on touch sensor panels applicable to smart cars have been actively conducted.

However, conventionally, the touch sensor panel applied to automobiles has a flat shape, which is inconvenient.

More specifically, a touch sensor panel widely used in an electric vehicle has a large surface, but is flat, so that a driver has to bend his / her body forward to operate the device, or to extend and extend the arm.

In this way, when the driver operates the touch sensor panel by moving his or her body while driving, it is difficult for the driver to stably check the road condition, which hinders safe driving.

Accordingly, when the curvature of the touch sensor panel is increased, the operator can easily touch the touch sensor panel without tilting the body forward, thereby solving the problem.

However, in the related art, there is no method of forming a touch sensor panel having a large curvature while performing the same touch function as a touch sensor panel having a flat shape, so that it has been difficult to apply the above technology.

In addition, in the conventional method of forming the touch sensor panel so as to have a curvature, only the method of applying the heat and pressure directly to the portion to be formed in the flat touch sensor panel was employed. Therefore, it is difficult to always apply the same pressure to the same position depending on the product, and it is difficult to produce a uniform quality product.

Accordingly, there is a need for a vacuum thermoforming apparatus for a hemispherical touch sensor panel capable of forming a hemispherical shape of a touch sensor panel.

SUMMARY OF THE INVENTION The present invention provides a vacuum thermoforming apparatus for a hemispherical touch sensor panel for forming a flat touch sensor panel into a hemispherical shape.

According to an aspect of the present invention, there is provided a touch sensor panel comprising: a fixing part for fixing a touch sensor panel; A resonance coupled to the fixed portion; And a heater unit arranged to move to an upper portion of the touch sensor panel and to heat the touch sensor panel. The vacuum unit has the same shape as the inner surface of the vacuum chamber, The vacuum thermoforming apparatus of the hemispherical touch sensor panel according to the present invention comprises:

In one embodiment of the present invention, the fixing portion includes: a lower fixing plate having a lower through-hole formed at a center thereof; An upper fixing plate hinged to an upper portion of the lower fixing plate and having an upper through hole; And a toggle clamp for fixing the fixing plate in a closed state.

According to an embodiment of the present invention, the vacuum unit may include a heater block coupled to the lower through-hole and having a concave surface at the center of the upper surface thereof; And a vacuum pump connected to the vacuum hole provided on the concave surface, wherein the vacuum pump discharges air positioned between the concave surface and the touch sensor panel to the outside through the vacuum hole.

In an embodiment of the present invention, the concave surface of the heater block may be hemispherical.

In one embodiment of the present invention, at least one of the vacuum holes is formed at the outermost portion of the concave surface, and the air suction pressure of the plurality of vacuum holes is uniformly maintained.

In one embodiment of the present invention, the outermost portion of the concave surface may be curved.

In one embodiment of the present invention, the heater unit includes: a heater module having a heating function; And a transfer module provided on one side of the heater module, wherein the transfer module moves the heater module to the left or right side.

In one embodiment of the present invention, the controller may further include a controller for individually adjusting the temperature and the heating time of the heater module and the heater block, and adjusting the vacuum pressure and time of the vacuum pump.

In an embodiment of the present invention, the touch sensor panel includes a base plate and a transparent conductive layer formed on the upper surface of the base plate.

The effect of the vacuum thermoforming apparatus of the hemispherical touch sensor panel according to the present invention will be described as follows.

According to the present invention, a flat touch sensor panel can be formed into a hemispherical shape.

Also, even for the novice user, the touch sensor panel can be easily hemispherically formed using the control unit.

Further, according to the present invention, it is possible to individually control the heating temperature of the heater block and the heater, the vacuum pressure and the time of the vacuum pump by the control unit, and the touch sensor panel is formed into a hemispherical shape in accordance with the material of the touch sensor panel .

Further, according to the present invention, a semi-spherical touch sensor panel of uniform quality can be manufactured. Specifically, since conventional products are locally subjected to thermal deformation and pressurized to obtain a curvature, a bending deviation may occur depending on the position of thermal deformation in the manufacturing process. However, according to the present invention, as the inner side of the vacuum chamber becomes a vacuum state, the heated touch sensor panel touches the concave surface and a touch sensor panel having the same shape as the concave surface of the vacuum chamber can be obtained.

It should be understood that the effects of the present invention are not limited to the above effects and include all effects that can be deduced from the detailed description of the present invention or the configuration of the invention described in the claims.

Then, the controller waits until the heater module 310 and the heater block 410 reach and maintain the set temperature. In this case, the amount of heat input from the heater module 310 and the heater block 410 can be accurately calculated by the touch sensor panel P.

Next, as shown in FIG. 1, the upper fixing plate 220 is lifted up by using the handle 222.
