The present invention relates to an inverting device of a liquid crystal module, and more particularly, to a side surface of a liquid crystal panel for curing a taper carrier package (hereinafter referred to as TCP) connecting a liquid crystal panel and a printed circuit board of the liquid crystal module. The present invention relates to an apparatus for inverting a liquid crystal module by 180 degrees and rotating it by 90 degrees with respect to a horizontal plane in order to apply silicon along the same.

When the liquid crystal panel including the upper and lower glasses is completed and the upper and lower glasses overlap, the lower glass is exposed from the upper glass because two adjacent side portions are larger than the upper glass. A pair of printed circuit boards is disposed along two adjacent sides of the exposed upper glass, and TCP is disposed in an exposed portion of the upper glass therebetween, so that the electrode pads of the printed circuit board and the liquid crystal panel are electrically connected via the TCP. By connecting to, one liquid crystal module is realized.

On the other hand, since TCP is simply mounted on the lower glass, there is a high possibility that TCP may be damaged or, in particular, detached from the lower glass in a subsequent assembly process. Therefore, before the subsequent assembly process, a process of applying silicone to the portion where TCP is disposed and curing it to increase the bonding force of TCP is preceded.

By the way, when the liquid crystal module is transferred to the silicon coating process, if the TCP is directed upward, there is a risk that the TCP may be damaged by an external impact. In order to prevent this, the liquid crystal module, which is transported in a state accommodated in the tray, is configured to be transported in a state where TCP is directed downward.

Therefore, in the silicon coating process, the liquid crystal module in the above state is inverted again by 180 degrees, and the TCP must be rotated by 90 degrees because it is disposed along two adjacent sides of the liquid crystal module. Conventionally, such reversal and rotation operations have been relied on by hand.

However, when the reversal and rotation operations are performed manually as described above, since the worker handles the glass by hand, the stress is applied to the TCP, which has caused the failure. In addition, there is a problem in that static electricity is charged to the glass and the TCP during handling by hand. Further, during the reversal operation, a situation in which the printed circuit board collides with the tray and is damaged frequently occurs. In particular, since the reversal and rotation operation is performed in the state exposed to the outside, there is also a problem that the particulate matter in the TCP, causing serious damage.

Accordingly, the present invention has been made to solve all the problems of the conventional method described above, so that the liquid crystal module is automatically inverted and rotated without depending on the manual operation, so that the TCP is damaged and the printed circuit board is broken. It is an object of the present invention to provide an inverting device of a liquid crystal module which can reliably prevent a situation and contamination by fine particles.

In order to achieve the above object, the inversion device according to the present invention has the following configuration.

The tray in which the liquid crystal module is housed is placed in a stage disposed on one side of the surface of the work table of the inversion chamber. Four guide blocks are arranged at each corner of the stage to closely support the tray. On the outer side of the stage, a reference stage providing a reference of the liquid crystal module is disposed, and the reference stage is connected to a rotary actuator to perform a rotational movement from horizontal to vertical or vice versa. An inversion driving unit for inverting the liquid crystal module 180 degrees is arranged in the center of the surface of the work table. The inversion drive unit includes a motor, a pulley and a timing belt, and the inversion axis extends from the pulley.

The vacuum adsorption part which adsorb | sucks a liquid crystal module by vacuum pressure is provided in the inversion shaft. The vacuum suction unit includes an inverting plate provided on the inverting shaft, a rotating support cylinder provided on the inverting plate, a rotating cylinder rotatably inserted in the rotating support cylinder, and an absorbing plate installed in the rotating cylinder to suck the liquid crystal module. At least two or more handles are arranged in the rotating cylinder at intervals of 90 degrees, so that the suction plate can be rotated precisely by 90 degrees. On the other hand, a plurality of vacuum pads are attached to the adsorption plate, and the liquid crystal module is adsorbed onto the adsorption plate while being subjected to a buffering action. In addition, it is preferable that a pair of shock absorbers are disposed in the central surface portion of the work table to control the inverting plate in a horizontal position at both horizontal positions of the inverting plate and to mitigate an impact at the moment of reaching the position. In addition, a filter for removing particulates and an ion generator for preventing static electricity are preferably disposed on the inversion chamber.

According to the configuration of the present invention described above, the liquid crystal module accommodated in the tray is inverted by 180 ° by the inversion driving unit in a state of being adsorbed by the vacuum adsorption unit, and in this state, the handle is applied after the silicon is applied along one side of the liquid crystal module. The silicon is applied to the other adjacent side by turning, and then the liquid crystal module is returned to its original position by the inversion driving unit again. As such, since the inversion operation except for the application of silicon is made automatically, the problem caused by the manual work is basically solved.

Meanwhile, the reference stage 31 serving as a reference of the liquid crystal module is rotatably disposed on the left side of the stage 20. The reference table 31 is connected to the rotary actuator 30 mounted on the workbench 11, thereby selectively rotating in a horizontal or vertical state according to the inversion operation. That is, in the inversion operation, the reference stage 31 is in a horizontal state, otherwise it is in a vertical state.

The inversion driver 40 is disposed at the center of the surface of the work table 11. The inversion drive part 40 includes the motor 41 mounted to the work bench 11 as a drive source.

More specifically, the vacuum suction unit 50 includes a reverse plate 51 provided on the reverse shaft 43. The rotation support part 52 is provided in the inversion plate 51, and the rotating cylinder 53 is rotatably inserted in the rotation support part 52. As shown in FIG. The rotary support 52 preferably includes a generally used roller bearing. The rotary cylinder 53 is preferably provided with at least two handles 54 at equal intervals of 90 degrees, so that the rotary cylinder 53 can be rotated precisely by 90 degrees.

In addition, in order to prevent contamination of the inversion chamber 10, the filter 70 may be disposed above the inversion chamber 10, and the ion generator 80 for preventing static electricity may be disposed below the filter 70. desirable.

Hereinafter, an operation of inverting the liquid crystal module by 180 degrees and rotating 90 degrees in a horizontal state with the inversion device according to the present embodiment configured as described above will be described in detail.

The worker places the tray containing the liquid crystal module on the stage 20. The tray is then firmly supported and fixed with four guide blocks 21. On the other hand, in this state, the reference stage 31 is in a vertical position, and the vacuum suction unit 50 is disposed on the right side.

In this state, the reference stage 31 is rotated in a horizontal state by the rotary actuator 30, and the operator aligns the liquid crystal module by pushing the reference stage 31. Then, the motor 41 of the inversion drive unit 40 is operated, and the rotational force is transmitted to the inversion shaft 43 through the pair of pulleys 45 and the timing belt 43, whereby the inversion shaft 43 is Rotate 180 ° to the left.

Therefore, the whole vacuum adsorption part 50 also rotates to the left with the inversion shaft 43. FIG. As the suction plate 55 reaches the left horizontal position and the suction plate 55 comes into contact with the left shock absorber 44, the applied shock is alleviated. In this state, the vacuum pressure is transferred to the adsorption plate 55 and the vacuum pad, so that the liquid crystal module is adsorbed to the adsorption plate 55.

When the adsorption of the liquid crystal module is completed, the entire vacuum adsorption part 50 is rotated back to the original horizontal position by the reverse rotation of the motor 41. At this time, the adsorption plate 55 faces upward, and thus the entire liquid crystal module is exposed upward. The operator standing in front of the inversion chamber 10 applies silicon along the TCP portion on the corresponding side of the liquid crystal module.
