Abstract

PROBLEM TO BE SOLVED: To improve a device so that a defective crimped terminal can be easily detected by adding the absolute value of the difference between a crimping force and a standard pattern value, and judging the defective when the added value is a set value or more. SOLUTION: When terminal crimping is started, a judging part 25 clears a memory for recording the added value T of a difference adding part 24. A crimping force difference calculating part 23 reads an output value Pt from a pressure sensor 20, and successively reads a reference value pt to time (t) recorded in a reference pattern recording part 22. The calculating part 23 performs an operation of St =|Pt -pt |. The judging part 24 records an abnormality when the calculated difference St is larger than a preset value S0 . The difference adding part 24 adds the calculated pressure value to the record value recorded in the memory, and performs an operation of Tt =Tt-1 +St to renew the added value. When the crimping is finished, the judging part 25 outputs no good when the abnormality by St >S0 is recorded, and further outputs no good when the added value T in the memory is larger than a set value T0 .

2. Description of the Related Art As a conventional method for detecting a defective crimp terminal, for example, the method described in Japanese Patent Laid-Open No. 1-185457 has been used. When crimping a terminal to a terminal of a coated electric wire, the coating of the terminal of the coated electric wire cut into a certain length is peeled off by a certain length, and a terminal having a certain shape and size is attached to the terminal and crimped. That is, as shown in FIG. 6A, in the terminal crimping, the cover grip portion T of the terminal T is
Reference numeral 1 denotes a conductor gripping portion T that securely grips the covering portion W1 of the electric wire W over the entire circumference and leaving a small distance from the covering portion.
2 is crimped so that the conductor (core wire) W2 is securely gripped over the entire circumference, and the terminal T is crimped to the end of the electric wire W.

The crimping of the terminal T to the electric wire W is automatically performed by the crimping device, but at the time of crimping, a part of the conductor W2 protrudes from the conductor grip portion T2 (so-called "core wire spill", FIG. b)), the cover gripping portion T1 of the terminal T grips the conductor W2 (insulator lowering, FIG. 6C),
Alternatively, various crimping defects occur such that the conductor gripping portion T2 grips the coating W1 (resin gripping, FIG. 6D).

The conventional method for detecting a crimp defective terminal is the sum of the crimping force with respect to the time during normal operation and the sum of the crimping force with respect to the time during actual operation as indicated by the one-dot chain line. When the difference between and is greater than or equal to the set value, it is determined to be defective. That is,
Whether it is normal or defective was judged from the difference in the areas of the curves shown by the relationship between the time and the pressing force shown in FIG.

As described above, conventionally, crimping is normally performed by the difference between the total crimping force with respect to time when normally crimped and the total crimping force with respect to time actually crimped. I was trying to determine whether or not. Therefore, for example, as shown in FIG. 8, when the area indicated by A and the area indicated by B are equal, the difference is 0 and it is determined that the operation is normal. The number of defective products mixed in the determination result increases. Further, at time t 1 in FIG. 8, there is a large difference from the standard value, but in such a case as well, the probability of failure is high, but it is ignored in the total sum and the difference becomes 0, which is normal. To be judged.

As described above, according to the present invention, the following effects can be obtained. The absolute value of the difference between the crimping force and the reference pattern value is added, and when the added value is equal to or greater than the set value, it is determined to be defective, so if it is different from the reference pattern, it is added to the added value and The crimping defective terminal can be detected. Also, when the absolute value of the difference between the individual crimping force and the reference pattern value is greater than or equal to the set value, it is judged as defective, so if there is any abnormality in the crimping process, It is possible to detect an abnormality, and it is possible to reliably detect a defective crimp terminal. In addition, because the absolute value of the difference between the crimping force and the reference pattern value is divided by the reference pattern value, the change in the small crimping state is emphasized to reliably detect the crimping defective terminal. can do.
