Abstract

PURPOSE:To recognize a frame having a defect with the naked eyes by forming a mark which can be recognized with the naked eyes on the frame wherein the defect is detected, and by only viewing a strip shaped body whose inspection is finished. CONSTITUTION:A feeding reel 1 feeds a TAB tape (strip-shaped body) 3. A winding reel 11 winds the strip-shaped body 3. An automatic inspecting part 31 sends an image which is obtained with a line sensor camera 33 into a signal processing device 35. The pattern of the image is matched with the pattern of a reference image which is stored beforehand. Thus the presence or absence of a defect is judged. The position of the defect in the frame is stored in a memory device through the signal processing device 35. When the information that the defect is detected is received with a puncher 61 as a marking means from the signal processing device 35, the puncher 61 is operated after the frame having the defect is sent to the position of the puncher 61. Then, a hole is punched in the strip-shaped body 3. The hole which is formed at this time has the diameter which can be readily recognized with the human eyes.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic belt-shaped body inspection device, and in particular, the present invention relates to an automatic inspection device for a strip-shaped body, and in particular, a belt-shaped body constructed by connecting a plurality of frames to be inspected. The present invention relates to an automatic belt-shaped body inspection device suitable for inspecting the presence or absence of a band-shaped body.

[Conventional technology]

TAB (Tape Automated B.

The nding method is known as one of the four techniques for mounting IC chips, and is widely used because of its high processing accuracy and ability to perform bulk bonding. This TA
The TAB tape (also called "film carrier tape") used in Method B is a film made of polyimide, for example, on which copper leads are formed for bonding an IC. A large number of frames are successively wound on a reel, like the frames of a movie film.

Before actually bonding ICs to this TAB tape, it is necessary to inspect it for defects such as damage or missing copper leads. Such inspection is performed frame by frame using image recognition technology such as pattern matching (for example, TAB film carrier lead inspection system,
MV-5100, manufactured by Toshi Co., Ltd.). If a defect is discovered in a certain frame, that frame will have an I
C is not honed and the frame becomes essentially unnecessary, but for -i, the frame part is not removed from the viewpoint of inspection efficiency, and the defective frame is skipped at the mounting stage. rc is bonded. That is, in the conventional TAB tape inspection device, when a defect is found in a certain frame, the position of the frame is stored in an external storage means, and then the frame with the defect is identified based on this stored information in the mounting stage 1c. IC
I try not to bond.

[Problem to be solved by the invention]

Conventional TAB tape inspection equipment stores the position of a frame with a defect in an external storage means, but an operator cannot tell whether or not there is a weir flaw on the TAB tape just by looking at the TAB tape (strip). I can't judge. Therefore, in order to know which frame has a flaw at the stage of IC mounting, it is necessary to regenerate the external storage means, resulting in poor workability.

Furthermore, conventional TAB tape inspection equipment had the disadvantage that if there were defects in multiple consecutive frames, the portion where IC could not be mounted would be longer, making it impossible to perform prompt processing at the RC mounting stage. .

The present invention has been made based on the above-mentioned circumstances, and an object thereof is to provide an automatic strip inspection device that can visually recognize a defective frame just by visually observing the inspected strip. It is something to do.

Further, the present invention has been made based on the above circumstances, and it is possible to recognize a frame with a defect with the naked eye, and when a defect is detected over a predetermined number or more consecutive frames, It is an object of the present invention to provide an automatic belt-shaped body inspection device that can automatically cut out this portion.

[Means to solve the problem]

A first aspect of the invention to achieve the above-mentioned object is to inspect each frame by the inspection means while the strip formed by connecting a plurality of frames to be inspected is sent out from the supply means and wound up on the winding means. In an automatic strip inspection device for inspecting the presence or absence of defects in a strip, marking means is provided at a stage subsequent to the inspection means for attaching a mark that can be recognized with the naked eye to frames in which scratches are detected based on information from the inspection means. It is characterized by this.

A second invention for achieving the above-mentioned object is a method for detecting a defect in a predetermined number or more consecutive frames after the marking means of the automatic strip inspection device of the first invention. In some cases, the continuous frame portion is cut out and a cutting and joining means is provided for cutting off the continuous frame portion and joining the band-like bodies at the front and back of the cut continuous frame portion.

[Effect]

According to the first aspect of the invention, when a defect is detected in a certain frame, the information is sent to the marking means using the above-described configuration. The marking means waits for the frame in which the defect has been detected to be transferred to the position of the marking means, and then applies a mark that can be recognized with the naked eye to the frame. This allows the user to identify frames with defects in the strip at a glance during the use stage.

According to the second aspect of the present invention, when a defect is detected in a predetermined number or more of consecutive frame portions, the information is sent to the cutting and joining means. The cutting and joining means cuts out the continuous frame portion in which the defect has been detected, and rejoins the band-like bodies before and after the continuous frame portion.

As a result, there will be no more than a predetermined number of defective frames consecutively present in the inspected strip.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a basic configuration diagram of a TAB tape inspection device which is an embodiment of the present invention.

In FIG. 1, this device includes a supply reel (supply means) 1 that supplies a TAB tape (strip) 3,
It has a take-up reel (winding means) 11 for winding up. Further, between the supply reel 1 and the take-up reel 11, a position detection device 21, an automatic inspection section (inspection means) 31, an edge fitting section 41, a visual inspection section 51, a puncher (marking means) 61, an operation section 71 and a splicer (cutting and joining means) 81 are provided.

The supply reel 1 on which the TAB tape 3 is wound has a T
An interleaver 5, which serves as a protective film to prevent damage caused by contact between the AB tapes, is also wound at the same time. The reel 7 is for winding the interleaver 5 separately from the TAB tape 3. On the other hand, TAB that has been inspected
When winding tape 3 with take-up reel 11, reel 1
Another interleaver 15 is sent out from 7, and again TAB
Together with the tape 3, it is wound around the winding loop II.

The position detection device 21 is for detecting which part of the TAB tape 3 is being inspected, and the position detection device 21 detects which part of the TAB tape 3 is being inspected. , the number of times the tape passes through (or is blocked by) the sprocket hole provided in the edge piece of the TAB tape 3 is counted.

The automatic inspection section 31, which serves as an inspection means, is a section that automatically inspects weir flaws such as damage and pattern deviation for each frame using image recognition technology. The resulting image is sent to the signal processing device 35.
The presence or absence of defects is determined by performing pattern masoching between this image and a pre-stored reference image.

The position of the defective frame on the TAB tape 3 is stored in a storage device (not shown) via the signal processing device 35. The offline dialog system 101 connected to the automatic inspection section 31 allows the automatic inspection section 31 to arbitrarily change the criteria for determining damage and the like. - There are various types of damage and dimensional deviations, and the criteria for determining defects differ depending on the accuracy required for the IC to be mounted. Therefore, by providing this offline dialogue system 101, the operator can flexibly respond to the intended use and required quality of the automatic inspection section 31 and the TAB tape 3.

The verification section 41 is for displaying the weir defects inspected by the automatic inspection section 31 on a television screen. That is, when a defect is found on the TAB tape 3 by the automatic inspection section 31, a signal indicating the position of the defect is sent from the signal processing device 35 to the TV camera position control section 43. T
Based on this signal, the V camera position control section 43 moves the television camera 45 to the position of the defect and sends the image signal to the television monitor 47. The operator can check this image for defects as needed.

The visual inspection section 51 has the same role as the verification section 41, but whereas the verification section 41 checks for defects through the television monitor 47, it checks defects using an optical stereoscopic microscope. The NTiH portion is observed with the naked eye.

The television camera 45 or the television monitor 47 may have insufficient resolution, and in such cases the visual inspection section 51
The function of the verification section 41 can be supplemented by the following. Further, when the verification section 41 does not operate due to a failure, defects can be confirmed by the visual inspection section 51.

When the puncher 61 serving as a marking means receives information indicating that a defect has been detected from the signal processing device 35 of the automatic inspection section 31, it waits until the frame with the weir defect is transferred to the position of the puncher 61 and then operates. and perforate the TAB tape 3.

The diameter of the hole provided at this time is such that it can be easily recognized with the naked eye, for example, 5 nm. Also automatic inspection section 3
1 has a function of specifying not only the presence or absence of a defect but also the type of defect, marking may be performed accordingly.

Instead of operating the puncher 61 under the control of the signal processing device 35 as described above, punching can also be stopped by the impossibility button 73 of the operating section 71. In this way, even if the automatic inspection section 31 determines that the part is defective, the operator can check it in the herification section 41 or the visual inspection section 51 and ultimately determine that it is possible to mount the IC. If so, it is possible to avoid drilling holes in the frame. In this case as well, multiple types of markings are possible depending on the type of defect. In this embodiment, a puncher 61 is used as a marking means, but other marking means may be used as long as it can be recognized with the naked eye. For example, special characters or symbols may be attached to a frame with a flaw.

The splicer 81, which serves as cutting and joining means, is a device that, when a large number of defects are detected across consecutive frames of the TAB tape 3, cuts out several consecutive frames and rejoins the front and back of the part. FIG. 2 is a schematic perspective view of this splicer 81. When weir flaws are continuously detected on the TAB tape 3 over a predetermined number of frames or more (for example, 10 frames or more), information about the frames with weir flaws is sent from the signal processing device 35 of the automatic inspection section 31. The information is sent to the splicer 81. Based on this information, the splicer 81 successively cuts one portion of the defective portion using a special cutter 83, and also cuts the end surface of the front portion 3a and rear portion 3b of the cut portion. are butted together as shown in Fig. 2 and joined with splicing tape 85. Thereafter, by rotating and tilting the forming cutter 8 in the direction of arrow Y in Fig. 2, the splicing tape 8
3. At the same time, cut out the protruding portion of the TAB tape 3, and at the same time, make a sprocket hole in the splicing tape 83. A predetermined number or more consecutive frames with defects can be removed from the TAB tape 3 inspected in this manner.

Although the above embodiment has been explained using a TAB tape inspection device as an example, the present invention is not limited to the above embodiment, but can be widely applied to general long article inspection devices.

〔Effect of the invention〕

As explained above, according to the present invention, a mark that can be recognized with the naked eye is provided on a frame in which a defect is detected in the automatic inspection device, so that a user can immediately identify a frame with a defect when using the strip. It has the effect of being able to be confirmed.

Further, according to the present invention, an operator can immediately identify a frame with a defect, and if there are many consecutive defects in the frame, the consecutive frame parts are cut out, so that the frame can be removed at the stage of use. It is possible to provide an automatic strip inspection device that can speed up processing at the stage of use without causing a large number of consecutive unusable frames.
