Abstract

(57) [Summary] [Structure] A metal fitting position detection unit is provided on the drive unit that moves the arm section in the left-right direction, and the drive unit is stopped when the metal fitting position detection unit contacts the fixed metal fitting and detects its position. The arm unit is driven to lower the hand unit, and when the substrate gripped by the hand unit reaches the position of the fixture, the substrate is separated and placed on the fixture. [Effect] Even if the belt of the belt conveyor that conveys the board meanders, the board can always be correctly placed on the fixing metal fittings fixed on the belt, thus preventing the quality of the board from deteriorating and improving the productivity. The yield can be improved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a substrate loading / unloading device for loading / unloading a printed wiring board to / from a belt conveyor type processing device when manufacturing a printed wiring board used for electronic equipment.

[0002]

[Prior Art]

 When manufacturing printed wiring boards used for electronic equipment, the conventional board loading / unloading equipment for loading / unloading printed wiring boards to / from a belt conveyor type processing device is used for starting adjustment. The board loading and unloading positions are mechanically determined, and during operation, the positions are repeated and reproduced.

[0003]

[Problems to be solved by the device]

 The conventional substrate loading / unloading device described above does not cause any problem when the belt conveyor belt of the processing device moves in a fixed position, but in actual operation, the belt may meander. , The position for inserting and removing the printed wiring board (board) is displaced. In particular, in a processing apparatus having a belt conveyor in which a metal fitting is fixed to a belt and a substrate is placed on the metal fitting, the deviation of the substrate loading / unloading position becomes remarkable due to the meandering of the belt. For this reason, there is a drawback in that the substrate cannot be gripped and the surface of the substrate is scratched or the substrate is damaged, so that the quality of the substrate is degraded and the production yield is reduced.

[0004]

[Means for Solving the Problems]

 The substrate loading / unloading device of the present invention is a substrate loading / unloading device comprising a hand part for holding a substrate, an arm part for vertically moving the hand part, and a driving part for horizontally moving the arm part. A metal fitting position detection unit is provided which is attached to the drive unit and which detects the position of a fixed metal fitting provided on a belt on which the substrate is placed and conveyed.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a front view showing an embodiment of the present invention, and FIG. 2 is a front view showing an operation state of the embodiment of FIG.

In FIG. 1, the fixture 3 is fixed to the belt 1 of the metal mesh type belt conveyor, and the substrate 4 is placed thereon. The belt 1 is continuously driven by the belt driving roller 2 (arrow B) to move. The hand part 5 grips the substrate 4 and places it on the fixture 3, or removes the substrate 4 from the fixture 3. The arm portion 6 moves the hand portion 5 in the vertical direction (arrow C in FIG. 2). The drive unit 8 moves the arm unit 6 in the left-right direction (arrow A). The metal fitting position detection unit 7 is attached to the drive unit 8, and the tip of the metal fitting position detection unit 7 contacts the fixing metal fitting 3 to detect its position.

In the board loading / unloading apparatus configured as described above, when the board 4 is placed on the fixed fitting 3, the board 4 is gripped by the hand portion 5 and the fitting position detecting portion 7 is lowered. The drive unit 8 is moved to the left while the arm unit 6 is raised (the state shown in FIG. 1). When this movement causes the metal fitting position detection unit 7 to contact the fixed metal fitting 3 and detect its position, the drive unit 8 stops its motion, and the arm unit 6 holds the substrate 4 with the hand unit 5. Descends with. When the hand unit 5 descends and the substrate 4 reaches the position of the fixing metal fitting 3 (state of FIG. 2), the grasped substrate 4 is released and placed on the fixing metal fitting 3, and the hand unit 5 moves to the arm. Raised by part 6. The substrate 4 placed on the fixture 3 moves together with the belt driven by the movement of the belt driving roller 2.

[Effect of the device]

 As described above, the substrate loading / unloading device of the present invention is provided with the metal fitting position detection part in the drive part for moving the arm part in the left-right direction, and when the metal fitting position detection part contacts the fixed metal fitting and detects its position. Stop the drive part and drive the arm part to lower the hand part, and when the board held by the hand part reaches the position of the fixing bracket, separate the board and place it on the fixing bracket. This has the effect that even if the belt of the belt conveyor that conveys the substrate meanders, the substrate can always be placed correctly on the fixing tool that is fixed on the belt. This has the effect of preventing the decrease and improving the production yield.
