Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for handling and accurately placing a surface mount device (hereinafter referred to as SMD) in a socket.

[Conventional technology]

FIG. 3 (al, (bl) is a plan view and a cross-sectional view showing the state when the SMD is stored in the tray. In the figure, (1) is the tray, (2) is the 8MD, t8)t
i) Pocket inside the lei, (4) is the wall of the pocket, (6
) is the SMD lead, +61, fγ) is the gap with the pocket wall (4).

FIG. 4 is a diagram showing the positioning method of j9 MD,
In the figure, (8) is an SMD suction head, (9) is a positioning table, and (CO) is a socket.

Next, the operation will be explained. There is a gap (6) 7Cγ) between the SMD (2) stored in the tray (1) and the pocket wall (4), and the SMD (2) is adsorbed by the suction head (8) as it is, and is inserted into the socket etc. Even when I moved it to a new location, the position shifted when it was picked up, so I couldn't place it accurately.

[Problem to be solved by the invention]

To position the SMD (2) in the conventional tray (1), as shown in Figure 4, after suctioning it, drop it onto the -degree positioning table (9) and use the taper! E M D It is necessary to perform centering (2), position it, adsorb it again, move it to the socket 10), and insert it, which may increase the number of operations and lead bending due to the increased number of operations. There was a problem.

This invention was made in order to solve the above problems, and the SMD on the tray (1) can be stored in one simple operation.
(2) It is an object of the present invention to obtain a method for positioning surface-mounted devices that can position all devices simultaneously.

[Means to solve the problem]

In the SMD positioning method according to the present invention, when a surface mount device housed in a tray is taken out from the tray and placed in a socket etc., the leads are aligned against the wall of the pocket in the tray by centrifugal force and inertia. 1 positioning.

[Effect]

In the positioning method of the present invention, the tray is shaken by the rotational force of the rotor l)-actuator to generate centrifugal force and move the SMD in the pocket to the outside.

〔Example〕

Hereinafter, this invention will be explained based on the drawings. FIG. 1 is a block diagram showing an SMD positioning device according to an embodiment of the present invention. In the figure, (1) is a tray, and (2) is an SM
D, σD are rotary actuators, αz is cam, C
The fulcrum of the 131H rocker arm and 1141id rocker arm, σ51 is the tray holder.

FIG. 2 (aj, (bl) is a plan view and a cross-sectional view showing the state after the positioning operation is performed with the device in FIG. 1,
In the figure, (8) is a pocket, C4) is a pocket wall,
(5) is the SMI lead, and (61) and (71) are the gaps after the positioning operation.

When the rotary actuator [111 is activated, the cam σ2 attached to its shaft rotates, causing the rocker arm (13
Drive 1. Rocker arm (131 is the branch [14
Rotate the tray holder [151] around 1, and the S M D
(2) Rotate together to generate centrifugal force. Therefore,
When rotary actuator σD stops rotating, S M
D C2) hits the pocket wall (4) in pocket (8) due to inertia, and S enters all pockets (8).
M D (2) is the gap (61
) becomes 0 and is aligned and positioned.

Furthermore, in the above embodiment, a rotary actuator and a rocker arm were explained, but an air cylinder may be used for driving, and a plate cam is used at the point of action without using a fulcrum to transmit rigid force, and centrifugal force is generated by the guide of the plate cam. [Effects of the Invention] As described above, according to the present invention, positioning can be performed without taking out the SMD from the tray.
If the SMD is placed in a tray, it is possible to perform highly accurate positioning without using replacement parts such as a positioning stand, and there is an effect that bending of the lead due to the number of hand links is eliminated.
