  The liquid crystal display panel 200 on which the third and fourth circuit boards 203c and 203d are mounted is rotated 180 degrees after being lifted by the second transport table 38. Then, after the second transport table 38 is lowered to a height away from the lower surface of the liquid crystal display panel 200, a fourth circuit board 203d is formed on one long side of the liquid crystal display panel 200 as shown in FIG. The third circuit board 203c is simultaneously mounted on the other long side.

  While the third and fourth circuit boards 203c and 203d are mounted on the liquid crystal display panel 200 by the second mounting unit 1B, the second transfer table 38 is retracted from the lower surface of the liquid crystal display panel 200 and moved to the first. Enters the lower surface of the liquid crystal display panel 200 held by the holding portion 41 of the mounting unit 1A and waits. At the same time, the third transfer table 39 enters and waits on the lower surface of the liquid crystal display panel 200 held by the holding portion 41 of the second mounting unit 1B.

  When the third and fourth circuit boards 203c and 203d are mounted on the liquid crystal display panel 200, the third transfer table 39 is lifted to float the liquid crystal display panel 200 from the holding unit 41. Next, the third transport table 39 is driven downstream to transport the liquid crystal display panel 200 between the pair of third mounting units 1C.

  The liquid crystal display panel 200 conveyed between the pair of third mounting units 1C is provided at the other end in the longitudinal direction by a pair of third cameras 47 provided on the side of the third mounting unit 1C. A pair of alignment marks (not shown) is imaged. The liquid crystal display panel 200 is positioned in the X, Y, and θ directions between the pair of third mounting units 1C based on the imaging result.

  When the liquid crystal display panel 200 is positioned, the third transport table 39 is lowered to a height at which both ends in the short direction of the liquid crystal display panel 200 are held by the pair of holding portions 41. In this state, as shown in FIG. 6E, the fifth circuit board 203e is mounted on one end of one side of the liquid crystal display panel 200 and the sixth circuit board 203f is mounted on one end of the other side at the same time.

  When the fifth and sixth circuit boards 203e and 203f are mounted on one end portion of one side and the other side of the liquid crystal display panel 200, the third transfer table 39 is raised and the liquid crystal display panel 200 is rotated 180 degrees.

  Next, after the third transport table 39 is lowered to deliver the liquid crystal display panel 200 to the holding unit 41, it is retracted from the lower surface of the liquid crystal display panel 200 and is held by the holding unit 41 of the pair of second mounting units 1B. It enters into the lower surface of the liquid crystal display panel 200 and waits. At the same time, the fourth transfer table 40 enters and waits on the lower surface of the liquid crystal display panel 200 held by the holding portions 41 of the pair of third mounting units 1C.

  A pair of third mounting units 1 </ b> C is provided at the other end of the pair of long sides of the liquid crystal display panel 200 that is rotated 180 degrees by the third transfer table 39 and held by the holding unit 41. As shown in FIG. 5, the fifth circuit board 203e and the sixth circuit board 203f are mounted simultaneously. As a result, two kinds of six kinds of first to sixth circuit boards 203a to 203f are mounted on the peripheral portion of the liquid crystal display panel 200, for a total of twelve.

  When the fifth and sixth circuit boards 203e and 203f are mounted on the liquid crystal display panel 200 by the third mounting unit 1C, the fourth transport table 40 is lifted to float the liquid crystal display panel 200 from the holding portion 41. The liquid crystal display panel 200 is transported to the panel carry-out section 4B and accommodated in a case (not shown).

  Thus, according to the display panel assembly apparatus of this embodiment, a pair of first to third mounting units 1A to 1C for mounting six types of circuit boards 203a to 203f on the liquid crystal display panel 200, respectively. Are arranged at predetermined intervals in the Y direction, and the first to third mounting units 1A to 1C are arranged adjacent to each other along the transport direction of the liquid crystal display panel 200.

  Therefore, since the arrangement length of the six mounting units 1A to 1C in total can be reduced to about half as compared with the case where they are arranged in a row, a long installation pace is not required.

  Moreover, the circuit board 203 can be simultaneously mounted on a pair of opposing sides of the liquid crystal display panel 200 by each of the pair of mounting units 1A to 1C facing each other. Therefore, the tact time required for mounting can be shortened to about half compared to the case where the circuit board 203 is mounted on each side of the liquid crystal display panel 200.

  The first to fourth X rails 21 to 24 are arranged such that a part of the end faces the end of the adjacent transport rail in parallel. Furthermore, a holding portion 41 that holds the liquid crystal display panel 200 that is transported and positioned between each pair of the first to third mounting units 1A to 1C is provided.

  Therefore, for example, the liquid crystal display panel 200 transported by the first transport table 37 between the pair of first mounting units 1A is held by the holding portion 41, so that the liquid crystal display panel 200 is placed between the first mounting units 1A. The first transport table 37 transported to the back can be returned to the panel supply unit 4A and the next liquid crystal display panel 200 can be supplied for standby, and the second transport table 38 can be moved from between the pair of first mounting units 1A. The liquid crystal display panel 200 to be carried out can enter the lower surface side and be in a standby state.

  Therefore, when the first and second circuit boards 203a and 203b have been mounted on the liquid crystal display panel 200 between the pair of first mounting units 1A, the liquid crystal display panel 200 is paired by the second transport table 38. The second liquid crystal display panel 200 is transported between the second mounting units 1B, or the next liquid crystal display panel 200 is transported between the pair of first mounting units 1A by the first transport table 37 from the panel supply unit 4A in a short time. Therefore, the tact time can also be shortened by these matters.

  Such a reduction in tact time can be achieved when the third and fourth circuit boards 203c and 203d are mounted on the liquid crystal display panel 200 by the pair of second mounting units 1B, or by the pair of third mounting units 1C. The same applies to the case where the fifth and sixth circuit boards 203e and 203f are mounted on the panel 200.

  The present invention is not limited to the above-described embodiment, and can be changed without departing from the gist of the invention. For example, the type and number of circuit boards provided in the peripheral part of the liquid crystal display panel are not limited. In short, if the circuit boards are mounted on at least a pair of opposing sides of the liquid crystal display panel, The invention can be applied.
