Abstract

PROBLEM TO BE SOLVED: To improve operating efficiency of a device without stopping a supply operation even when a component is lacked, by detecting presence of an electronic component at a component taking-out position, and, when no electronic component is detected, repeating pitch feed until an electronic component is detected, within a predetermined number of times. SOLUTION: Before starting automatic operation, an electronic component line 11 is set on a component holding part 4, and the number of repeating times R (for example, R=3) is set. Then automatic operation is started, and the electronic component line 11 is fed by a pitch. At a component taking-out position A, presence of an electronic component 1 is detected with detecting means 8a and 8b. When no electronic component 1 is detected, detached tapes 3a and 3b are scrapped. If the number of repeating times R (e.g. R=3) is continuously reached, automatic operation is stopped. If continuously not reached, returning to pitch feed.

As shown in FIG. 3, the transfer head 7 is held by driving means (not shown) and moved forward and backward in the drawing direction a. , After holding the electronic components 1 one by one,
As shown in FIG. 4, the electronic component 1 is configured to be moved to the insertion portion B in the next process, positioned, and delivered to the insertion portion B to be sequentially supplied.

The first embodiment of the electronic component supply method according to the present invention having the above-described configuration of the supply device is shown in FIG.
1 to S9 will be described below.

Prior to the start of the automatic operation, first, the electronic component chain 11 is set in the component holding unit 4 in S1, and the number of repetitions R (for example, R = 3) is set in S2. Next, automatic operation is started. In step S3, the electronic component chain 11 is fed by one pitch. This S
The details of the pitch feed process of No. 3 are as follows.
The tape portions 3a and 3b of the electronic component chain 11 are sandwiched, pulled out by one pitch, and the leading electronic component 1 is positioned at the component extraction position A. In S4, the tape unit 3 for one electronic component
The electronic component 1 is separated from the electronic component chain 11 by cutting a and 3b. In S5, the presence / absence of the electronic component 1 at the component take-out position A is detected by the detection means 8a and 8b. Electronic component 1 in S5
Is detected, the process proceeds to the next S6, where the electronic component 1
Is supplied to the insertion section B in the next step, and the process returns to the pitch feed of S3.

If the electronic component 1 is not detected in S5, the process proceeds to S7 and the separated tapes 3a and 3b are discarded. In S8, if the transition from S5 to S7 has reached the repetition number R (for example, R = 3) continuously, the procedure proceeds to S9 to stop the automatic operation. In S8, if the transition from S5 to S7 is continuously less than the repetition number R, the process returns to the pitch feed of S3. After the automatic operation is stopped in the above S9,
If necessary, the process proceeds to S1, a new electronic component series 11 is set, and the automatic operation is resumed via S2. The input of the repetition number R (for example, R = 3) of S2 is the same
When replenishing 1, the previous value may be used without re-inputting. In addition, even when the supply of all the electronic components 1 of the electronic component series 11 is completed, the transition from S5 to S7 in S8 is repeated continuously and eventually reaches the number R, and the automatic operation is automatically stopped. .

Next, a second embodiment of the electronic component supply method of the present invention will be described below with reference to steps S11 to S19 shown in FIG.

Prior to the start of the automatic operation, first, the electronic component series 11 is set in the component holding unit 4 in S11, and the total pitch number N (for example, N = 500) of the electronic component series 11 is set in S12. Next, automatic operation is started. In step S13, the electronic component chain 11 is fed one pitch. The details of the pitch feed process in S13 are the same as those in Step S3. In S14, the tape portions 3a and 3b for one electronic component are cut and separated from the electronic component chain 11.

In step S15, the electronic component 1 is set at the component pick-up position A.
Is detected by the detection means 8a and 8b. If the electronic component 1 is detected in S15, the process proceeds to the next S16, where the electronic component 1 is supplied to the next step B, and then proceeds to S17.
If the electronic component 1 is not detected in S15, the process proceeds to S19 and the separated tapes 3a and 3b are discarded.
Move to. In step S17, the number of pitch feeds completed by the electronic component chain 11 is counted up by one. If the number of pitch feeds reaches the total pitch number N (for example, N = 500), the electronic component chain 11 is sent to the electronic component chain 11. It is determined that there is no remaining number, and the process proceeds to S18 to stop the apparatus.
Then, a new electronic component chain 11 is set, and the automatic operation is resumed via S12. If the number of completed pitch feeds is less than N in S17, it is determined that there is the remaining number of electronic components 1 in the electronic component chain 11, and the process returns to pitch feed in S13 to continue the automatic operation.

In the second embodiment, step S12
Although the total pitch number N of the electronic component series 11 is set in the above, the total number of electronic components of the electronic component series 11 may be set instead of the total pitch number N. In this case, the electronic component supply number or the electronic The number of detected components may be compared with the total number of electronic components.

In the above embodiment, step S4 or S4
At 14, the presence or absence of the electronic component 1 is detected after the tape parts 3a and 3b are separated, but may be detected before the tape parts 3a and 3b are separated.

In the above embodiment, the photoelectric sensors 8a, 8b
Is detected at the same position as the component take-out position A, but the present invention is not limited to this. For example, the detection position may be located one pitch before the component take-out position A. Should be detected. Further, the photoelectric sensors 8a and 8b are used as the detection means of the electronic component 1,
Instead, another sensor such as a capacitance type proximity sensor may be used. In addition, the electronic component series 11 held by the component holding unit 4 is picked up by the transfer head 7 and pulled out by one pitch. However, the component holding unit 4 extends the electronic component series 11 by one pitch. Is also good.

In the above embodiment, an axial electronic component has been described. However, the present invention is not limited to this. The present invention can also be applied to a radial electronic component in which the tip of a lead is taped at a constant interval with a line of tape. It goes without saying that the effect of (1) can be obtained.

[0024]

According to the electronic component supply method of the first invention,
If no electronic component is detected at the component take-out position, the pitch feed of the electronic component series is repeated until the electronic component is detected within a preset number of times, and the electronic component is positioned at the component take-out position.
