Abstract

PURPOSE:To make appearance visual inspection after sealing unnecessary, and save labor for the appearance inspection process by equipping a means to visually verify a seal trace which is heated, and a means to decide good or not for the seal trace, based on the said image recognition information. CONSTITUTION:A boss type tape 1 which is adhered to a cover tape 2 moves to the right, following the intermittent motion of a drive side pin rotor 4 and a following side pin rotor 5, and is carried directly under a camera 16 and performs fixed position stop. At this time, the boss type tape 1 which has reached directly under the camera 16 is visually verified by the camera 16 by a lighting part 17. That is, for the boss type tape 1 which has given the fixed position stop, the image of a seal trace 15 is taken by the camera 16, and the area of the seal trace is processed by a CPU and operation process device, and being good or not is decided conforming to the decision reference which is previously input. At this time, when it is a good article, sealing is continuously performed, and when being defective is decided, the motion will be stopped, and alarm is given to an operator, and feed-back is waited on.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a packaging device with a sealing device for storing parts in a boss-shaped plastic tape and pasting a heat-sealable cover tape thereon. [Prior Art] Figures 2 to 6 show this type of conventional apparatus. This boss-shaped tape 1
A seal-type cover tape (hereinafter referred to as blade bar tape) is inserted on top, and 3 is a heat block for bonding these. Figure 2 is a front view of the entire device, and Figure 8 is a diagram of Figure 2.

14 is a receiving rail for receiving the tape 1, a conveying rail for guiding the double-sided tape 1, and 15 is a sealing mark heated by the protrusion 31 of the heat block 3. Indicates ○ Next, the operation will be explained. Pitch holes 1a are inserted in the boss-shaped tape 1 into the pins d and 5, which are provided by equally distributing the circumferences of the driving-side pin rotor 4 and the driven-side pin rotor 5, which are rotated in a constant pinch by a drive source (not shown). It is transported intermittently. The boss-shaped tape 1 being conveyed is held down by tension rollers 6 and 7 to prevent it from coming off from the bin 41 or 51, and moves at a fixed pitch for storing parts (not shown). When the center of the four parts of the boss-shaped tape 1 that has been moved by a fixed pinch comes to the middle position of the big amp needle 8, the big amp needle 8 big-amps the part by a mechanism not shown and stores it in the recess of the boss-shaped tape 1. do.

Next, the screw-shaped chip 11 containing the part passes through a place marked with a presser 9 to prevent the part from flying out. The boss-shaped tape 1 that has passed through the presser plate 9 then passes under the guide 10 that guides it down to adhere the cover tape 2, and after passing through the guide 10, the boss-shaped tape 1 (=, the concave containing the parts) The heat block 3 is operated in accordance with the intermittent operation of the bin rotor 4.5, and while the bin rotor 4.5 is stopped, the heat block 3 is lowered and the cover tape 2 is blocked. It is heated from above.

In addition, the heat block 3 is made of a metal material such as a heat-conducting pot or U, and is used to feed the 11i11 humidity results to the heater ■, which is the heat source, and the temperature regulator (not shown), which controls the set temperature. It has a built-in temperature sensor.

By lowering the heat block 3 heated to the set temperature, the screw-shaped tape and cover tape 2 are connected to the support rail 1.
3 and comes into contact with the cover tape 2, the protrusion 31 of the protuberance 3 and ℃ serve as adhesive surfaces and are sealed. Insertion of parts 711: When the boss tape is in progress, it is in the descending state to the heat block 3, and the pickup needle 8
If no part is inserted, or if there is an error in the device, the conveyance of the screw-shaped tape 1 is stopped and at the same time, the heat block 3 returns to the raised position. When the conveyance of the boss-shaped tape 1 is restarted after the error is cleared, the heat block 3 is lowered at the same time as the start and adhesion is performed.

In this way, the adhesion of the boss tape 1 and the cover tape 2 is successively carried out, and a certain amount of the adhesion is completed on a take-up reel (not shown).

Before shipping the wound boss shadow tape I and cover tape 2) to the customer, cut out a part of the area where part D is not included in the state shown in Figure 5, and place it on the bone scale shown in the figure. using a peeling angle of 0 to 15 and a peeling speed of 300 cod/
An inspection is performed in which cover tape 2 is peeled off in minutes and the minimum and maximum values of the spring scale are read at that time to determine pass/fail;

Note that the judgment value of the above-mentioned peel strength varies from company to company, but the Japan Electronics Industry Association (Elmu J) specifies a value of 20 to 709 as a provisional value.

[Problem to be solved by the invention]

Apart from measuring peel strength, this conventional method involves the extra work of visually inspecting the entire length of the sealed tape. In addition, one problem that arises at the customer's site is a fatal defect in which parts spill due to lack of sealing, and this must be inspected.

This invention has been made to solve the above-mentioned problems, and its purpose is to eliminate the need for visually inspecting the appearance of the seal portion. [Means for Solving the Problems] Packaging according to the present invention The device uses a camera to recognize the presence and area of seal marks where the boss-shaped tape and cover tape are adhered, analyzes the image, and uses Iori's calculation results to alert the sealing device operator to any abnormalities. be.

[Effect]

In the present invention, instead of the visual inspection of the sealed portion that was performed by an operator outside the sealing device, the inspection can be performed inside the sealing device using image recognition and arithmetic processing by a camera.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a front view showing an embodiment of the present invention, and in the figure,
1 to 14 are exactly the same as the conventional example described above. ・16 is a camera for image recognition placed on the rear side of the heat block 3, and 17 is a lighting section attached to the camera to illuminate the seal mark 15. , 18 are an OPU and an arithmetic processing unit connected to the camera and used to determine the quality of the seal mark from the image information captured by the camera 16.

Next, the operation will be explained. The process in which the boss-shaped tape 1 is conveyed and the cover tape 2 is bonded by the heat block 3 is the same as that in the conventional example, and will therefore be omitted.

The boss-shaped tape 1 is adhered to the cover tape 2 and moves to the right in FIG. At this time, the image of the camera 16 is recognized by the illumination portion 17 on the boss-shaped tape 1 that has come directly below the camera 16.

That is, the camera 16 captures an image of the sticker mark on the boss-shaped tape 1 that has stopped at a fixed position, and calculates the area of the sticker mark by C.
It is processed by the PU and the arithmetic processing unit, and is judged to be good or bad according to the judgment criteria input in advance.

In this case, if the product is good (=, the seal is pulled hard, and if it is determined to be defective, the operation is stopped, an alarm is issued to the operator, and the feed bank is waited for.0 [Effects of the invention] As described above. The sealing device according to the present invention has an accurate seal trace inspection function that replaces the human eye and brain, so there is no need for the operator to visually inspect the entire length of the tape after sealing, which was a problem in the past. This has the effect of saving labor in the inspection process.
