Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a marking device for an electronic component series that marks, for example, a pass/fail judgment mark for each component on a frame of an electronic component series in which small electronic components such as transistors are arranged in series.

Conventionally, this type of marking device for electronic components has been used to mark the pass/fail judgment mark of each electronic component on a frame to which lead terminals of electronic components are integrally attached. It is known that the marking means of the device is brought into contact with the frame portion near the frame to directly stamp the marking, or to print the marking by transfer.

However, in the case of such conventional devices, no matter which method is used, the marking means must be strongly pressed against the marking surface of the frame when marking, so if the frame is not held firmly, the frame may There is a problem in that deformation or damage to the connection between the electronic components and the frame can lead to accidents. In addition, in any of the above conventional devices,
The marking means needs to be fixed at least in directions other than the pressing direction, so the frame is moved intermittently at regular pitches.
The structure of this feeding mechanism is complicated, and therefore, failures often occur in the feeding mechanism.

The present invention has been made in view of the above-mentioned problems. First, when marking a frame of an electronic component series, a spray nozzle is adopted, and this nozzle is placed in a position where it does not come into contact with the marking surface of the frame. By providing a marking device, the primary purpose is to eliminate damage to a series of electronic components, and the spray nozzle is intermittently fed at regular pitches by an intermittent transfer means of a relatively simple structure. As,
The second objective is to fix the electronic component chain in a predetermined position until the marking is completed, thereby eliminating the need for pitch feeding of the electronic component chain and simplifying the device.
The purpose of

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 shows a series of electronic parts marked by the apparatus of the present invention. This series 1 of electronic parts is made up of dozens of small electronic parts 2, 2, etc., such as transistors, placed on a frame 3. The array is fixed at a constant pitch P. Each electronic component 2 has one of the lead terminals 4 drawn out from its lower end connected integrally to the frame 3. This frame 3
is a long rectangular flat plate made of a thin metal plate, and has a pitch feed hole 5 formed therethrough at a position directly below each electronic component 2.

FIG. 2 is a plan view showing an example of the electronic component series marking device according to the present invention. 1, an intermittent transfer means 8 for intermittently moving the spray nozzle 7 within a constant stroke S, and a control means 9 for controlling the injection operation of the spray nozzle 7. A pass/fail determination mark M is marked with a spray nozzle 7 on a portion of the frame 3 near the rejected (or accepted) part of each electronic component 2. This spray nozzle 7 is mounted on a slider 10 in a fixed position, and a nozzle opening 11 of the nozzle 7 faces the marking surface 3a of the frame 3 at a predetermined distance l.
As schematically shown in FIG. 3, this nozzle opening 11 is formed by forming a marking ink outlet 12 and a ring-shaped compressed air outlet 13 on the outer periphery of this outlet 12. The air outlet 12 communicates with an inner passage 14 of the spray nozzle 7, and the compressed air outlet 13 communicates with an outer passage 15. Of these, the inner passage 14 is connected to the ink tank 16.
The outer passage 15 is connected via a solenoid valve 17 to compressed air supply means 18 .

The ink tank 16 and the solenoid valve 17 are placed on the left and right sides of the spray nozzle 7, and the slider 1
It is installed on 0.

This slider 10 has a rectangular base 19 on which a spray nozzle 7, an ink tank 16, a solenoid valve 17, etc. are mounted, and guide grooves 20, 20... and connecting parts 21, 21 are provided on the bottom surface of this base 19. , and are mounted on the intermittent transfer means 8 so as to be movable in the left and right directions.

This intermittent transfer means 8 includes a pulse motor 22,
It consists of a slider transport mechanism 23 and a slider guide structure 24 driven by this motor 22. This slider guide structure 24 has support walls 25, 25 erected on the left and right sides, and guide rails 26, 26 are installed in front and behind between both the support walls 25, 25,
Guide grooves 20, 20, . . . of the slider 10 are fitted onto both guide rails 26, 26 so as to be slidable in the left-right direction. The slider transfer mechanism 23 includes a drive pulley 27a interlockingly connected to the drive shaft 22a of the pulse motor 22, and a pivot shaft 2 installed between brackets 28, 28 protruding from the left support wall 25.
An endless belt 29 is stretched between the driven pulley 27b rotatably supported on the belt 8a, and connecting parts 21, 21 of the slider 10 are connected and fixed to a part of the upper surface of the endless belt 29. It is. The control means 9 is electrically interlocked with the pulse motor 22 and has a circuit section (not shown) for storing the marked positions of rejected products (or accepted products) in the electronic component series 1.

Next, the operation of the above structure will be explained. First, a single item of the electronic component group 1 is moved to a predetermined position A by the feeding means 6.
will be installed in At this time, the slider 10 is located at the left end of the slider guide structure 24, so that the spray nozzle 7 is also located at the left end of its stroke S. From this position, the slider 10 is moved at a constant pitch P in the direction of arrow a by the pulse motor 22.
When the spray nozzle 7 reaches the marked position of the rejected product (or accepted product), a control signal from the control means 9 is transmitted to the solenoid valve 17, which opens and sprays. Compressed air is sent to the nozzle 7, which operates to spray ink, spraying ink onto the marking surface 3a of the frame 3, and marking the pass/fail determination mark M. In this way, when the spray nozzle 7 reaches the right end of the stroke S and the pass/fail judgment of the electronic component series 1 is completed, the control means 9
A control signal is transmitted from the pulse motor 22 to the pulse motor 22, which continuously drives the slider 1 in the opposite direction.
0 is returned to the left end of the slider guide structure 24. During this return operation, the feeding means sends the pass/fail determined electronic component series 1 to the next process, and
The operation of installing the undetermined electronic component series 1 at the predetermined position A is completed.

As explained above, according to the present invention, when marking, for example, a pass/fail judgment mark on an electronic component series, a spray nozzle is used as the marking means,
Since the nozzle opening of the nozzle is arranged at a predetermined distance from the frame marking surface of the electronic component series, marking can be performed without the marking means coming into contact with the marking surface,
It is possible to prevent the electronic parts from being deformed or damaged. In addition, since the electronic component chain is fixed and the spray nozzle is moved intermittently, the mechanism can be simplified compared to conventional equipment in which the electronic component chain must be moved at regular intervals. It became possible. Furthermore, in the present invention, the control means is electrically interlocked with the transfer means and stores the mark position of the accepted or rejected products of the electronic component series, and the control means
The slider is moved by controlling the transfer means, and when the spray nozzle mounted on the slider coincides with the marking position, a control signal is output to the spray nozzle, and the spray nozzle is moved from the nozzle opening to the marking surface. Since the ink is controlled to be ejected by
To change the mark position of an acceptable product or a rejected product, it is only necessary to change the memory of the control means, and since the control of the mark by the control means and the movement of the transport means are linked, it is possible to accurately mark the mark. You can make a mark.
