Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electronic component storage case used as an automatic supply means for electronic components automatically mounted on a printed circuit board.
This invention relates to an electronic component packing device that packs and stores chip-type electronic components.

Conventional technology In general, there are various packaging methods for electronic components that are automatically mounted on printed circuit boards, such as the tabbing method, bulk method, and magazine packing method.The tabing method is mainly used to package chip-type electronic components. , the bulk method is applied.

Among these, in the case of the tabbing method, the electronic components are arranged and housed and held by the carrier tape, so that the electronic components can be smoothly supplied to the mounting head when the carrier tape is pitch-fed. However,
In this case, the electronic components must be individually aligned and arranged on the tape surface of the carrier tape using a unique loading means, and the tape surface of the carrier tape must be covered with a cover tape or the like. In addition, in order to extract electronic components with a suction head, the cover tape must be peeled off from the carrier tape, and the carrier tape, including the cover tape, is disposable, so overall the cost is high. become.

On the other hand, when using the bulk method (for example,
No. 2-280129) requires no effort to pack the electronic components because it is only necessary to store multiple electronic components separately inside the storage case, but it is not necessary to arrange the electronic components from the storage case. Because of the need to accurately deliver each item one by one, the delivery structure, which extends to the delivery opening of the storage case, must be constructed in a complex manner.

In place of these packaging formats, the applicant has previously proposed storage cases for electronic components that have different packaging formats (Utility Model Application Publication No. 2003).
-37892).

The storage case for electronic components has a disc-shaped case body, and this case body has a storage path for electronic components that continues in a spiral shape inside the case body, and a spiral groove located at the outermost periphery of the storage path. An electronic component outlet is formed on the end surface of the case body on an extension of the case body, and an air feed hole is formed which communicates the outer surface of the case body with the groove of the storage path.

This storage case can accommodate multiple electronic components arranged in a spiral storage path, and the electronic components can be precisely emptied along the storage path to the take-out port using compressed air sent into the storage path from the air inlet. By moving the pressure, electronic components can be delivered one by one from the outlet to the suction head.

Therefore, this electronic component storage case not only allows electronic components to be accurately delivered one by one by simply sending compressed air into the storage path, but also can be used repeatedly by refilling the electronic components. It is also economically preferable.

Problems to be Solved by the Invention The only way to further advance the practical application of the above-mentioned storage case is to make it possible to not only pack electronic components for the first time, but also to refill them extremely efficiently, and to store them without placing a large load on the electronic components. It is essential to develop pack packing means that can be quickly packed into the storage channels of the case.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic component packaging device that is ingeniously designed to satisfy the above-mentioned requirements.

Means for Solving the Problems In the electronic component packing apparatus according to the present invention, there is provided a parts feeder that arranges randomly loaded electronic components in a line in a predetermined direction and sends them out from the delivery port, and A shooter having a linear passageway for aligning and taking electronic components into the interior from the artificial part, and an air feeding passageway communicating between the outside and the inside of the passageway by a diagonal flow passage toward the outlet side of the passageway. , an air supply mechanism section that is connected to the air inlet path of the chute and sends pressurized air for the electronic components into the chute path into which the electronic components are taken, and the outlet of the chute and the ejection port of the electronic components are aligned. The device includes a case mounting stand that is positioned to hold the electronic component storage case so that it can be replaced one by one.

Function: In this electronic component packing device, the electronic components fed from the parts feeder are lined up in a line and taken into the passage of the chute, and the electronic components are picked up by the air feed path of the diagonal flow path toward the outlet side of the chute. By sending pressurized air into the passage of the loaded chute, the outlet of the chute and the ejection port of the electronic component can be aligned and the electronic component can be sent into the storage passage of the storage case held on the case mounting base. . In this air packing, the entire packing equipment is not a scale that can be constructed with a simple mechanism, and the electronic components are not subjected to any load from mechanical elements other than air pressure, so there is no damage to the electronic components during packing. It can be prevented. In addition, by appropriately setting the air pressure of the compressed air sent into the passage of the chute, electronic components can be quickly sent into the storage path of the storage case and packed, and the electronic components can be stored as they are packed. Since the pressurized air flowing into the channel can be released from the air hole of the storage case, electronic components can be smoothly stuffed deep into the storage channel. Furthermore, since multiple electronic components can be fed in line with the passage of the chute at the same time, packaging can be extremely efficient, and by managing the number of electronic components taken into the chute, the desired number of electronic components can be packed into the storage case. can be easily set up.

Embodiments will now be described with reference to the accompanying drawings.

In addition, this packing device packs electronic components sequentially fed from a parts feeder 1 through a chute 2 into a storage case 6 held by a case mounting table 4. The component storage path is set to have dimensions according to the size of the electronic component.

The parts feeder 1 includes a hopper into which electronic components are randomly fed from the electronic component manufacturing process, and a kite bar for electronic components spirally installed along the inner shoulder surface of the hopper.The hopper is vibrated with a vibrator. An ordinary multi-feeder can be used that aligns the electronic components that enter the kite frame in a line in the groove of the guide frame and feeds them out.

Following the parts feeder 1, a chute 2 is installed. The chute 2 is arranged such that the electronic component delivery port formed at the guide bar exit of the parts feeder 1 and the artificial part 20 are aligned, and the chute 2 is arranged so that the electronic component delivery port formed at the guide bar exit of the parts feeder 1 and the artificial part 20 are aligned, and the inlet part 20 is located within the plate thickness as shown in FIGS. A linearly communicating passage 21 is formed in the shape of a cavity with a predetermined length toward the outlet portion 22 . The passage 21 of the shooter 2 is equipped to take in the electronic components sent out from the parts feeder 1 in a line and to function as a buffer for simultaneously sending out a predetermined plurality of electronic components from the outlet section 12. That shooter 2
An air feed passage 23 is provided which communicates with the passage 21 from an appropriate position on the lower surface side. The air feed passage 23 is formed of diagonal passages 23a and 23b communicating with the passage 21 from left and right toward the outlet 22 of the passage 21.

The number of electronic components that can be delivered simultaneously is determined by the length of the passage 21 from the opening position of the passage 23b to the outlet 22 of the shooter 2. Also, on the lower surface of the chute 2, which is the proximal end side of the air feed path 23, a socket portion 23c for connecting an air vibrator of the air supply mechanism portion 3 is provided.

In addition to the air feed path 23, a counting sensor 24 such as a photo sensor or a laser sensor for detecting the number of electronic components fed can be provided. The counting sensor 24 can be installed on the passage surface of the inlet section 20, or can be installed on the side of a stopper for preventing parts from returning, which will be described later. Above this inlet part 20, a stopper 25 for preventing the return of parts such as a solenoid pulp or a cylinder for moving the tip of the bottle into and out of the groove of the inlet part 20 is disposed by being supported by the upright frame of the base 5, etc. Correspondingly, the entrance portion 20 is formed with an opening 26 through which the tip of the bottle of the stopper 25 for preventing parts from returning comes in and out.

The air supply mechanism section 3 intermittently sends positive pressure air into the passage 21 of the chute 2 by connecting an air pipe (not shown) to the socket section 23C of the chute 2 as described above. The timing can be set by operating the air supply mechanism 3 in response to a command issued from the counting sensor 24 when the number of electronic components detected by the counting sensor 24 reaches a predetermined number. In addition, the positive pressure air sent into this passage 21 is 3 to 4 k
With an air pressure of 0.5 to 1.0 g/cm', a sand diameter of 0.5 to 1.0 is sufficient.
Approximately 0 to 80 pieces can be fed into the storage case 6 from the outlet portion 22 of the shooter 2 at the same time. Case mounting stand 4
The holding frame 4a has holding frames 4a and 4b on which the storage case 6 can be exchanged as needed.

When the storage case 6 is held in an upright position by 4b, the mounting surface of the upright position is set so that an outlet for electronic components, which will be described later, is aligned with the outlet 22 of the shooter 2.

On the case mounting table 4, instead of holding the storage case 6 upright, the storage case 6 is placed horizontally so that the ejection port for electronic components and the outlet portion 22 of the shooter 2 are aligned. It can also be configured to do so.

The case body 60 of the electronic component storage case 6 is formed into a disk shape, as shown in FIGS. 4A to 4C. This case main body 60 is provided with an electronic component storage path 61 formed by connecting each of the spiral strips 61a to 61n in a spiral shape. An electronic component outlet 62 is formed in the end surface of the case body 60 via a straight path 61P.

In addition, in this case body 60, an air inlet hole 63 and an air discharge hole 64, which are used when sending out electronic components housed inside the storage path 61 from the outlet 62, are connected to the storage path 61 from the outer surface of the case body 60. It is provided as an air hole that communicates with the inside of the groove. Of these, air inlet hole 6
3 is two rows 6 spaced apart on one side ω1j of the case body εO.
3a to 63n are provided, and these are provided obliquely so that the air sent into the groove of the storage path 61 can be directed toward each other. A plurality of air discharge holes 64a to 64n are provided on the upper half side of the plate surface on the other side of the case body 6°, and each row 64a to 64n corresponds to each spiral strip 61a to 64n of the storage path 61.
They are aligned in the radial direction from the center position of the case body 1 in accordance with n. Incidentally, a rising edge 65 having an elliptical planar shape is provided at the molding position of the above-mentioned air feed hole 63 so as to surround each row 63a to 63n and is used as a fitting device for a coupling for blowing compressed air. Further, the electronic component outlet 62 is provided with a shutter 66 for separating and sending out the electronic components one by one, as shown in FIG. The shutter 66 has a locking pawl 66a that protrudes into the opening of the outlet 62, and a pin 66b is attached to the middle side in the longitudinal direction so that the locking pawl 66a can be freely moved in and out of the opening of the outlet 62. The other end is supported by a spring 66C via this pin 66b so as to be elastically supported.

In the electronic component packing device that packs electronic components into the storage case 6, the electronic component ejection port 62 is aligned with the outlet portion 22 of the shooter 2, and the storage case 6 is placed standing on the plywood of the mounting base 4. Place it. At this time, the shutter 66 of the storage case 6 is moved by means not particularly shown in the drawings.
6a is displaced from the groove of the outlet 62 to maintain the outlet 62 in an open state. At the same time, the electronic components are fed from the parts feeder 1 into the shooter 2 in a line arranged in a predetermined direction. When this number reaches a predetermined number, the air supply mechanism section 3 is activated in response to a detection command from the counting sensor 24. When the air supply mechanism 3 operates, the diagonal flow path 23a toward the outlet side of the chute 2
, 23b, pressurized air is supplied to the passage 21 from the air supply passage 23 of 23b.
This compressed air causes a plurality of electronic components to be sent out from the outlet section 22 of the shooter 2.

As the pressurized air is fed in, the stopper 25 is activated by a detection command from the counting sensor 24, similar to the air supply mechanism 3.
By operating the tip of the bottle and fitting the tip of the bottle into the opening 26 of the shooter 2, the artificial part 20 can be closed and the electronic components can be prevented from returning. The electronic components sent out from the outlet 22 of the chute 2 are immediately transferred to the storage path 60 of the storage case 6 from the electronic component ejection port 62 aligned with the pressure opening 22, and are internalized from the outermost spiral strip 60n. It can be fed even to the circumferential spiral strip 60a. If the electronic component is continuously fed with pressurized air for 0.3 to 1.0 seconds, it can be reliably transferred to the innermost spiral strip 60a.
Since the electronic components are appropriately discharged from the storage path 64 and are not trapped inside the storage path 60, the electronic components can be smoothly moved along the storage path 60. When the feeding is completed, the air supply mechanism 3 is stopped and the pin tip of the stopper 25 is retreated from the opening 26 to open the opening 2o, thereby stopping the feeding of electronic components from the parts feeder 1 to the shooter 2. resume. By repeating this process, a predetermined number of electronic parts are packed into the storage case 6, and the packing rate is 1 minute per minute.
Approximately 000 pieces can be made at 0 speed.

Incidentally, to explain how the above-mentioned storage case 6 is used to supply electronic components to the suction head of an automatic mounting device, as shown in FIG. Then, the storage case 6 is installed in the electronic component automatic supply device 7. In this automatic electronic component supply device, the coupling 71 of the air feeding mechanism 70 is connected to the case body 6.
By fitting the rising edge 65 of o, the storage case 6
Equipped with a cover on the back side. When pressurized air is supplied to the coupling 71 from the air valve 72, each spiral thread 61a of the storage path 61...
- Pressurized air is sent to 61n. This compressed air is 1.5kg/cm2. 0. By intermittently blowing air at 3-second intervals, it is possible to forcefully feed the electronic components into the groove of the storage path 61 at an oblique angle, so that even a plurality of electronic components stored in the storage path 61 can be blown in one predetermined direction by the compressed air. Smooth pneumatic feeding is possible. When the compressed air is blown into the first electronic component and it moves close to the opening closed by the shutter 66 of the outlet 62 of the storage case 6, the push-up pin 73 that is driven in synchronization with the operation of the air valve 72 The shutter 66 is pressed to open the electronic component outlet 62, and the leading electronic component is pushed out into the cutout groove 74a of the stand 74 by the compressed air. After that extrusion, the receiver is on stand 7
4 moves forward, the electronic component is carried to the front position where the suction head H moves up and down, and is picked up by the nozzle tip of the suction head H and taken out to be mounted on a printed circuit board. After one electronic component is separated and sent out, the push-up pin 73 immediately moves downward, so that the shutter 66 closes the electronic component outlet 62 and waits until the air valve 21 is operated next. .

Effects of the Invention As described above, according to the packing device for electronic components according to the present invention, by sending compressed air to the chute that arranges and takes in a plurality of electronic components, the electronic components can be packed without damaging them. This makes it possible to pack items in a storage case at the same time, making packing extremely efficient.
