Guide Rail for Transferring Circuit Board {GUIDE RAIL FOR PCB FEEDING}

The present invention is a circuit board manufacturing apparatus for producing a large amount of circuit boards widely used in various electrical and electronic products, the present invention relates to a guide rail for conveying a circuit board installed on the circuit board pedestal, and more specifically to the circuit board The performance is improved by improving the drive belt structure for transporting, the support plate material for supporting the drive belt, the tension control structure of the drive belt, and the power supply structure for the drive motor.

In general, the circuit board manufacturing apparatus has a circuit component assembly apparatus 100 in the center, as shown in FIG. 1, before the circuit board supply means 110, and then the circuit board discharge means 120. The circuit part assembly apparatus 100 is provided, and the one or more circuit part assembly mechanisms 101 are used.

That is, the circuit board pedestal 130 is fixed to the rotating disk member 131 rotatable in the horizontal direction by a separate driving means (not shown) and the rotating disk member 131 as shown in FIG. The base plate member 132 having a rectangular opening 132a at the center thereof, and the drive belt 134 in the longitudinal direction are fixed in parallel to the upper inner side and the lower inner side in the opening 132a of the base plate 132. The branch is made up of a guide rail 133 and a circuit board stop means 135 for stopping the circuit board from the outside of the guide rail and fixing the circuit board at a fixed position.

The guide rail 133 used in the conventional circuit board support 130 as described above forms a guide groove 133b along the longitudinal direction on the inner surface of the guide member 133a, as shown in FIG. After the driving pulleys 133c and the driven pulleys 133d are respectively arranged at both ends of the groove 133b, the driving belts 134 are fastened to the driving pulleys 133c and the driven pulleys 133d in the longitudinal direction. Rotating, but the driving belt 134 is to be moved along the guide groove (133b).

However, such a conventional guide rail has the following disadvantages.

First, not only supporting the driving belt 134, but also to form a guide groove (133b) so that the circuit board is transported while being mounted on the driving belt 134, a narrow and long guide groove ( 133b) not only takes a lot of processing time but also has a disadvantage in that productivity is lowered and manufacturing costs are increased because it is difficult to process.

Second, since the driving belt 134 is relaxed or worn when used for a long time, it is necessary to adjust or replace the relaxed state to a tensioned state. However, in the conventional case, although there is a replacement, there is no structure that can finely adjust the relaxed state to a tense state.

Third, to drive the drive belt pulley 133c for rotating the drive motor 135 is attached to supply power, the conventional power supply structure is provided with a power supply terminal at the end of the guide rail to be elevated operation The contact portion is installed on the power supply terminal and the guide member corresponding to the position.

However, since the conventional contact portion is installed in a form in which the terminal block 136 is protruded and fixed at one end of the guide member as shown in FIG. 3, the terminal block 136 operates in a close position. There is a risk of interference with the bridge (unsigned).

Therefore, the present invention has been devised to solve the above-mentioned conventional problems. The main purpose of the present invention is not to manufacture a guide groove for the drive belt on the inner side of the guide member, but to provide a separate support plate for supporting the drive belt. In order to improve the productivity, and to reduce the manufacturing cost by improving the form of attachment, on the other hand, the device for inserting parts that is accessed from the bottom by making the thickness of the drive belt part as thin as possible It is intended to prevent interference even when approaching a close position.

Another object of the present invention is to be able to change the position of the driven pulley of the drive belt, to improve the easy structure to replace the drive belt and to adjust the tension.

Another object of the present invention is to supply power to the drive motor, to improve the structure of the contact portion to a structure that does not protrude so as not to interfere with the peripheral equipment.

The guide rail of the present invention for achieving the above objects is fixed to the pair of bar guide rails in parallel to the inner side facing each other in order to be transported while supporting both ends of the circuit board, A driving pulley and a driven pulley are provided at both ends to fasten the driving belt in the longitudinal direction, and to connect the driving motor to the driving pulley so as to be rotatable. The inner side of the driving belt support for preventing the driving belt from sagging. Fixing the mechanism, the one end of the guide rail is provided with a drive belt tension adjustment mechanism, the one end of the guide rail is configured to provide a power supply terminal for supplying power to the drive motor.
