DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting device for a TCP device in which the vibration of a punching device does not affect the operation of a transfer device.

[0002]

2. Description of the Related Art From a carrier tape formed by a TAB method, TCP (Tape Carrier Packa) is used.
ge) A mounting device for a TCP device that punches out a device and automatically mounts it on a substrate such as a liquid crystal panel has begun to be put into practical use.

Here, in a conventional mounting device for a TCP device, in order to make the entire device compact, a punching device for punching a TCP device from a carrier tape and a T
In many cases, a transfer device that transfers a CP device to a substrate is integrated. Further, the transfer device is provided with an observation device such as a camera for imaging the substrate and the TCP device for alignment at the time of transfer.

[0004]

Here, the TCP device has several tens or more leads of extremely narrow pitch, and when positioning at the time of transfer requires high positional accuracy, punching is required. Vibration during the punching operation of the apparatus is transmitted to the observation apparatus and other transfer apparatuses, and the recognition accuracy of the observation apparatus is deteriorated. Therefore, at present, the timing of imaging by the observation device is shifted from the timing of the punching operation so as to minimize the influence of vibration. However, even in this case, the vibration of the punching device is directly transmitted to the observation device or the like, and it is likely to cause a decrease in recognition accuracy, and by shifting the timing of the imaging and the punching operation, a loss time occurs, There has been a problem that the tact time of the entire mounting becomes long.

Accordingly, an object of the present invention is to provide a mounting device for a TCP device which can sufficiently suppress the influence of vibration during punching operation.

[0006]

A mounting device for a TCP device according to the present invention comprises a base, a transfer device mounted on the base and transferring the TCP device to a substrate, and a TCP device from a carrier tape. A punching device for punching and supplying to the transfer device, and a supporting means provided on the base and supporting the punching device, wherein a vibration absorbing member for absorbing vibration of the punching device is provided on the supporting means. ing.

[0007]

According to the above construction, the vibration of the punching device is absorbed by the vibration absorbing member and is hardly transmitted to the transfer device. For this reason, if the transfer device is provided with an observation device, the observation device has sufficient recognition accuracy even if the punching operation and the imaging timing of the observation device are matched, and there is no need to shift the timing, and the entire mounting Tact time can be shortened.

[0008]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view of an apparatus for mounting a TCP device according to an embodiment of the present invention, and FIG. 2 is an enlarged view of a portion P in FIG.

In FIG. 1, reference numeral 1 denotes a base, and A denotes a positioning device provided on the base 1 for positioning a substrate 2 such as a liquid crystal panel. 3 is an X table mounted on the upper surface of the base 1, 4 is a Y table, 5 is a θ table, 6 is a substrate 2
Is a substrate holder for holding a lower portion of the mounting position of the substrate 2 below, and 8 is a crimping tool for crimping the TCP device to the substrate 2.

Reference numeral B denotes a carrier tape supply device integrally provided on the left side of the base 1 in FIG. 9 is a vertical support plate, 10 is a shaft supported on the upper portion of the support plate 9, and is a supply reel on which a carrier tape 11 including a TCP device before punching and a separator 12 are alternately wound, and 13 is a carrier reel. A tension roller 14 for applying tension to the tape 11 and the separator 12, and a separator take-up reel 14 that is supported by a lower portion of the support plate 9 and collects the unnecessary separator 12. The carrier tape 11 goes around the tension roller 13 and is sent in the direction of the arrow N1, passes through the punching device C,
After the TCP device is punched, it is wound on a carrier tape take-up reel 15.

In the punching device C, 16 is an upper die supported so as to be able to move up and down, 17 is a lower die facing the upper die 16, and 18 is a cylinder which raises and lowers the upper die 16. And the punching device C
Is installed on a base plate 21 erected on the base 1 and horizontally supported by columns 20 corresponding to the support means. Reference numeral 30 denotes a transfer device provided on the base 1,
31 is a transfer nozzle for receiving the TCP device punched by the punching device C from below, and 32 is a T on the transfer nozzle 31.
This is a transfer head that sucks the CP device and mounts the CP device on the mounting position of the substrate 2 and the device receiver 33 erected on the base 1. Reference numeral 34 denotes an observation apparatus including a camera that captures an image of the mounting position of the substrate 2 and the TCP device from below. The point that the observation device 34 is provided on the base 1 and the recognition accuracy is poor if the vibration during the punching operation of the punching device C is directly transmitted to the observation device 34 is as described in the section of the prior art. is there.

In this embodiment, as shown in FIG. 2, a vibration absorbing member 40 is provided at a connecting portion P between the base plate 21 and the support 20.
Is provided. As shown in FIG. 2, the vibration absorbing member 40 of the present embodiment includes a block rubber 44 in which a nut 45 is fitted, sandwiched between an upper plate 42 and a lower plate 43. Bolts 41 to be screwed together with nuts 45
And a tightening bolt 46 passing through the base plate 21 is screwed into the base plate 21. That is, an elastic block rubber 44 is elastically mounted between the base plate 21 on which the punching device C is mounted and the column 20, and it is difficult to transmit vibration at the time of punching to the column 20. It was done. Of course, this means is not limited to the example shown, and the vibration absorbing member 40
0, or as a vibration absorbing member,
A coil spring may be used instead of the block rubber 44, or an elastic body and a damping element such as a damper may be used in combination.

According to the present invention, there is provided a mounting device for a TCP device.
A base, a transfer device mounted on the base and transferring the TCP device to the substrate, a punching device for punching the TCP device from the carrier tape and supplying the device to the transfer device, provided on the base And supporting means for supporting the punching device,
Since the vibration absorbing member that absorbs the vibration of the punching device is provided in the support means, the adverse effect of the vibration during the punching operation is suppressed, the accuracy of the transfer device can be kept good, and the tact time of mounting can be reduced. .
