The liquid crystal display panel 200 is positioned in the X, Y, and θ directions based on the imaging result of the second camera 46 as shown in FIG.

  When the liquid crystal display panel 200 is positioned, the second transport table 38 is lowered to a height away from the lower surface of the liquid crystal display panel 200 as shown in FIG. Thereby, both end portions in the longitudinal direction of the liquid crystal display panel 200 are sucked and held by the pair of holding portions 41. Next, the circuit board 203 is mounted on one side of the long side of the liquid crystal display panel 200 by the second mounting unit 1B.

  The second transfer table 38 lowered to a height away from the lower surface of the liquid crystal display panel 200 is removed from the lower surface of the liquid crystal display panel 200 while the circuit board 203 is mounted on the liquid crystal display panel 200 by the second mounting unit 1B. It retracts and enters the lower surface of the liquid crystal display panel 200 held by the holding portion 41 of the first mounting unit 1A and waits. At the same time, as shown in FIG. 3, the third transport 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. At this time, the first transfer table 37 stands by at the panel supply unit 4A.

  When the circuit board 203 is completely mounted on the liquid crystal display panel 200 in the second mounting unit 1B, the third transfer table 39 is lifted after the crimping tool 18 is lifted as shown in FIG. The liquid crystal display panel 200 on which the circuit board 203 is mounted is floated from the holding portion 41. Next, the third transport table 39 is driven downstream to transport the liquid crystal display panel 200 to the panel carry-out portion 4B and accommodate it in a case (not shown).

  At the same time, the liquid crystal display panel 200 on which the circuit board 203 is mounted on one side by the first mounting unit 1A is floated from the holding unit 41 by the second transport table 38 and is transported to the second mounting unit 1B. Are sequentially repeated.

Therefore, the overall tact time can be greatly shortened.

  In addition, the liquid crystal display panel 200 can be transferred from the first transfer table 37 to the second transfer table 38 without using a robot. Therefore, compared to the case of using a robot, the apparatus is not increased in size and complexity, and is advantageous in terms of cost.

  In order to image the liquid crystal display panel 200 with the first and second cameras 45 and 46 for positioning the liquid crystal display panel 200 with respect to the mounting units 1A and 1B, and for positioning, the first and second cameras 45 and 46 are used. 1. It is necessary to move the second transfer tables 37 and 38 in the X direction with high accuracy.

  In order to move the first and second transfer tables 37 and 38 in the X direction with high accuracy, it is required to lay rails that guide these transfer tables 37 and 38 with high accuracy. Conventionally, a rail having a length extending over the entire moving direction of the first and second transfer tables 37 and 38 is laid along the X direction of the base 1. That is, after the base 1 is installed in the factory, the parallelism and level of the rail are adjusted and laid on the base 1. For this reason, there has been a case where a great deal of labor is required when starting up the apparatus.

  Therefore, in this embodiment, first and second rail mounting members 19 and 20 having a length corresponding to the X direction of each mounting unit 1A and 1B are provided, and the first and second rail mounting members 19 and 20 are provided with the first and second rail mounting members 19 and 20, respectively. The main rail portions 21a and 22a of the two X rails 21 and 22 are laid with a preset accuracy.

  Then, after the first and second rail mounting members 19 and 20 are installed on the front end side of the base 1 at the factory, the first X rail is straddled across the first rail mounting member 19 and the panel supply unit 4A. Connecting rail portion 21b connected to main rail portion 21a of 21 and connecting rail connected to main rail portion 22a of second X rail 22 across first rail mounting member 19 and second mounting member 20 The part 22b is laid.

  In the liquid crystal display panel 200 placed on the first and second transfer tables 37 and 38, the first and second transfer tables 37 and 38 are the main rail portions 21a of the first and second X rails 21 and 22, respectively. , 22a to be imaged by the first and second cameras 45, 46, or positioned with respect to the mounting units 1A, 1B.

  Imaging and positioning by the first and second cameras 45 and 46 of the liquid crystal display panel 200 are required to be performed with high accuracy. On the other hand, the connection rail portion 21 b of the first X rail 21 simply places the liquid crystal display panel 200 on the first transfer table 37. Further, the connection rail portion 22b of the second X rail only waits for the second transfer table 37 to receive the liquid crystal display panel 200 on which the circuit board 203 is mounted in the first mounting unit 1A. Therefore, the laying accuracy such as the parallelism and level of the connection rail portions 21b and 22b is not required with high accuracy.

  Therefore, when installing the assembly device in the factory, the first and second X rails 21 and 22 need only lay connection rail portions 21b and 22b that do not require high installation accuracy. The laying operation of the first and second X rails 21 and 22 can be performed easily and quickly. That is, the apparatus can be easily started up.

  In addition, since the main rail portions 21a and 22a of the first and second X rails 21 and 22 are laid in advance with high accuracy, imaging and positioning of the liquid crystal display panel 200 performed using the main rail portions 21a and 22a. Can be performed with high accuracy.

  The main rail portion 23a of the third X rail 23 only positions the transport table 39 when the liquid crystal display panel 200 placed on the third transport table 39 is taken out by the panel carry-out portion 4B. The connection rail portion 23b only makes the third transfer table 39 stand by to carry out the liquid crystal display panel 200 on which the circuit board 203 is mounted in the second mounting unit 1B.

  For this reason, both the main rail portion 23a and the connection rail portion 23b of the third X rail 23 are not required to have high installation accuracy, so that installation of the third X rail 23 does not take time.

  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, in the above embodiment, two mounting units are arranged along the X direction in order to mount the circuit board on two of the four sides of the peripheral portion of the liquid crystal display panel. The present invention can be applied even when mounting units are arranged.

  Further, although the rail mounting member on which the X rail is laid is a separate member from the base, the mounting member and the base may be integrated.
