Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a camera lens barrel support mechanism in a tape bonder for bonding a pellet or a single bump to a lead provided on a carrier tape.

[Prior Art] A tape bonder detects the lead of a carrier tape, and also detects the position where a tool for joining the lead and a pellet or bump (the case of a pellet will be explained below) hits the lead (by checking the position of the mark on the tool). The present invention is equipped with a tape detection camera for detecting the pellet (detection) and an electrode detection camera for detecting the pellet position at a position away from the bonding position. The tape detection camera and the electrode detection camera each have a tape detection camera barrel and an electrode detection camera barrel, and the tape detection camera barrel and the electrode detection camera barrel are attached to a fixed plate. .

By the way, the pellet moves in the XY direction
It is placed on a table, and by moving the XY table, the pellet to be detected can be positioned below the camera barrel for electrode detection, so the camera barrel for electrode detection can be placed at the fixed position of the camera holder. is fixed. However, since the tape detection camera barrel needs to detect the lead position and tool mark position as described above,
A hole larger than the fixed part of the camera barrel for tape detection is provided in the camera holder, and the camera barrel for tape detection is inserted into this hole to detect the lead position or tool mark position detected by the tape detection camera. While observing on the monitor, I manually moved the tape detection camera barrel within the hole in the camera holder to adjust it.

In addition, as related to the camera lens barrel support mechanism in this type of tape bonder, for example,
Publication No. 59-161040 and Japanese Unexamined Patent Publication No. 63-20846 are cited.

[Problems to be Solved by the Invention] The above-mentioned conventional technology has the problem that the position of the camera is adjusted according to the operator's feeling, requiring skill and that highly accurate position adjustment cannot be performed.

An object of the present invention is to provide a camera barrel support mechanism in a tape bonder that allows for easy and highly accurate camera position adjustment.

[Means for Solving the Problems] The above object is to provide a camera barrel support mechanism in a tape bonder in which a plurality of camera barrels are attached to a camera holder, in which one of the plurality of camera barrels is attached to the camera holder. XY by manual operation
Solved by installing via an XY table that is moved in the direction.

[Function] By moving the XY table on which the camera barrel is attached in the X and Y directions using screws or other means, the camera barrel can be moved to any position on the XY plane with high precision. .

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2. A case 2 is fixed to the camera holder 1, and a cover 3 is fixed to the upper surface of the case 2. Two Y-direction guide plates 4.5 having Y-direction guide grooves are fixed at a constant interval to the case 2, and a Y-direction slide plate is disposed between the Y-direction guide plates 4 and 5. 6 is provided slidably in the Y direction. Y direction slide plate 6
Two X-direction guide plates 7 and 8 having guide grooves in the X-direction are fixed at a constant interval on the top, and an X-direction slide plate 9 is installed between the It is provided so as to be slidable in the direction. That is,
The Y-direction slide plate 6 and the X-direction slide plate 9
It constitutes an XY table that can be moved arbitrarily on the XY plane.

A female screw 10 is fixed to the Y-direction slide plate 6, and a Y-direction adjusting screw 11 rotatably provided on the case 2 is screwed into this female screw 10. In addition, the X-direction slide plate 9 has a rack 1.
2 is fixed, and a pinion 13 is meshed with this rack 12. The pinion 13 is rotatably supported by the X-direction guide plate 7, and an X-direction adjustment shaft 14 is fixed to the pinion 13. In addition, the Y-direction guide plate 5 has a Y-direction slide plate 6.
A lock screw 15 for locking is screwed together,
Similarly, a lock screw 16 for locking the X-direction slide plate 9 is screwed into the X-direction guide plate 7.

The X-direction slide plate 9 has a tape detection camera barrel 2 equipped with a tape detection camera 20 on the upper part.
The first mounting portion 21a is fixed. Holes 1a, 2a, and 3a are formed in the camera holder 1, case 2, and cover 3 so that the tape detection camera barrel 21 can move on the XY plane, and the Y-direction slide plate 6 has holes 1a, 2a, and 3a in the An elongated long hole 6a is formed. Further, a cover 22 is fixed to the tape detection camera barrel 21 so as to cover the hole 3a of the cover 3. Also fixed to the camera holder 1 is a mounting portion 24a of an electrode detection camera barrel 24 having an electrode detection camera 23 on the top thereof.

Next, the effect will be explained. The tape detection camera barrel 21 is located above the bonding position of the carrier tape (not shown).
4 are used by being placed above pellets (not shown).

The position adjustment of the tape detection camera barrel 21 is performed as follows. When the lock screws 15 and 16 are loosened and the Y direction adjustment screw 11 is turned, the Y direction slide plate 6 is guided by the Y direction guide plates 4 and 5 and moves in the Y direction. The Y-direction slide plate 6 is attached with the X-direction guide plate 7 and the X-direction slide plate 9, and the X-direction slide plate 9 is attached with the tape detection camera barrel 21, so When the direction slide plate 6 moves in the Y direction, the tape detection camera barrel 21 moves in the Y direction. When the X-direction adjustment shaft 14 is turned, the rack 12, that is, the X-direction slide plate 9, is guided by the X-direction guide plates 7 and 8 and moved in the X-direction by the pinion 13. Since the tape detection camera barrel 21 is attached to the X direction slide plate 9, when the X direction slide plate 9 moves in the X direction as described above, the tape detection camera barrel 21 moves in the X direction. . That is, when the Y-direction adjustment screw 11 and the X-direction adjustment shaft 14 are turned, the tape detection camera barrel 21 moves to an arbitrary position on the XY plane.

In this way, the tape detection camera barrel 21 is
Consists of a direction slide plate 6 and an X direction slide plate 9
Since it is attached to the XY table, the tape detection camera barrel 21 can be easily and at a high height detected at the lead pattern detection position of the mark on the tape (not shown) and the mark detection position on the tool (not shown). Can be adjusted to precision.

[Effects of the invention] As is clear from the above explanation, according to the invention, the camera barrel is attached to the camera holder via the XY table, so the position of the camera can be adjusted easily and with high precision. It can be carried out.
