Abstract

PURPOSE:To obtain a strong and sure aligning machine, by constituting the machine such that it picks up a conveyed part by a pickup wheel, synchronously rotated with a conveyer, to align the center position of a body of said part by an arm movable in the same angle. CONSTITUTION:A coaxial lead part 5, arranged in an order by a chain conveyer 1, is picked up by a pickup wheel 2, synchronously rotated with the conveyer 1, and guided by straightening blades 7a, 7b.

And the part 5 presses by a shoulder of its body end part the straightening blades 7a, 7b to be laterally spread toward the part advance direction. And the part is fed in a position, where it is released from the straightening blades 7a, 7b, into a pitch groove of a tape regluing pitch wheel 3. By this constitution, a strong and sure aligning machine is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous processing coaxial lead component alignment machine.

Conventional U.S. Patent Nos. 3,421,284, 4,213,286,
It was difficult to align and re-tape the automatically arranged coaxial lead parts in the coaxial lead part arrangement machine as shown in FIG.

In these conventional machines, the coaxial lead component alignment mechanisms were complex and unstable or unreliable.

To give an example, a blade driven by a flexible wire 13 that rotates in synchronization with the conveyor is provided between the conveyors, and coaxial lead parts 5. The lead was held down from both ends with a blade and aligned so that the left and right positions were centered on the conveyor.
Since it is released from the blade by the time it is re-taped, the alignment effect is lost. In addition, in the synchronous operation using the flexible wire 13, the mechanical life is short because the transfer processing speed is very high, 7 times per second or more.

It was causing trouble.

The alignment blade comes into contact with the parts and aligns them when the coaxial lead parts are pushed apart left and right by the cam 14 driven by the flexible wire [3] and the coaxial lead parts are positioned at the straight end part of the blade 15α15h. ,cam】
The blade 15α15h, which has been pushed wide left and right in step 4, is released from the cam 14 and rapidly closes by the force of the spring, so the blade always contacts the parts with an impact, and depending on the degree of that force, external force may be applied to the parts. There have also been cases where more than necessary is applied, causing component failure. Furthermore, the alignment effect is significantly reduced, especially when the body end of a coaxial lead component has a gently sloped surface. This is because the alignment blade 15α15h released by the cam is attached to the component body 5. Because of the impact, the parts often go over the slope, and as a result, the parts are lifted onto the alignment blade, which cannot perform the alignment function. Also, to prevent it from climbing over, press the blade from the top 17.18
If you try to actively work on parts with thin lead wires, you will end up pushing and bending the IJ-wire, which may cause problems if you try to process the parts with other machines such as subsequent automatic insertion machines. This has caused problems such as damage to the insertion head of the insertion machine, which requires a great deal of time and cost to restore.

Another example is U.S. Patent No. 570,842, in which the conveyor chain automatically feeds the alignment blade, but the transfer to the pitch foil for re-taping uses natural fall and slides down an arcuate surface. The component holding spring from below is a flat spring, and the spring force cannot be arbitrarily adjusted while the machine is running, making the adjustment difficult.

〔Effect of the invention〕

The present invention is designed to overcome these drawbacks of conventional machines.

Fig. 1, which will be explained in detail with reference to the drawings below, is a perspective view showing the entire coaxial lead parts aligning machine of the present invention. The foil 3 is a pitch foil for re-taping.

[Explanation of Examples]

The coaxial lead parts 5 arranged in order on the conveyor chain conveyor 1 are once aligned by the alignment blade 7 (α) 7 ( s)j The guided aligning blades 7(α) and 7(h) are bent at a certain angle so that the exits in the component advancing direction close to each other.The component picking foil 2 securely picks up the components from the chain 1. 4 to make it easy to pick up and transfer to pitch foil 3 for re-taping.
A cut is made as shown in the figure. All the transfer operations of these engaging coaxial lead groups are carried out in conjunction with a single drive source motor, so that no mistakes in transfer occur.

The coaxial lead component 5 fed between the alignment blades 7α7h by the pick-up foil 2 uses the shoulder at the end of its body to push the alignment blades 7tL7b to the left and right in the component advancing direction. The opening angle of the aligning blade 7α7h is so arranged that the fulcrum position 9 of the blade and the position of the connecting bin are the same so that the opening angle is the same on the left and right sides, and the alignment blades 7α7h can be expanded in the same way left and right in conjunction with each other. Also, in order to accurately transfer the tape from the pick-up foil 2 to the re-taping pitch foil 3, the top of the rung 8, which has a linear inclined surface, is picked up and sent by the foil 2, and the tape is re-taped at the position released by the alignment blade 7α7h. The leads of the component fed into the pitch groove of the pitch foil 3 are connected to each other and sandwiched with adhesive tape 4 from above and below the machine for re-taping, and are daped.

The greatest feature of the present invention is that the alignment blades 7α7b are arranged so that the timing of exiting the inclined surface 8 and transferring them to the next pitch foil 3 to be re-taped is the same and the effect of the alignment blades 7α7b is not impaired. Conventionally, the parts could not maintain the alignment effect from the alignment blade 15α15b to the re-tape position. The alignment blade 7α7h of the present invention always maintains a parallel positional relationship with the inclined surface 8 so as to maximize its function, and the opening angle for holding it is always inclined at the same angle depending on the size of the body of the part. The movable fulcrum 9 of the alignment blade 7α7h needs to be set at a right angle of 90° so as to be parallel to the plane. By arranging the parts in this way, the inclined surface 8 is lifted up by the foil 2 while the alignment blade 7α7h
The center of the body is aligned at the center position from the left and right in the direction of travel, and the tape is instantly reapplied, allowing coaxial lead parts whose body centers are uniformly aligned to be interconnected.

I believe that the effective functions of the present invention can be understood from the above.

This effect is exhibited when the component is automatically inserted into a printed circuit board by a subsequent automatic insertion machine. The alignment data for conventional automatic alignment machines is that the large part body has a length of 16n to 5.51m in diameter, and the small part has a length of 2 stm and a diameter of 1.3 m.
According to the data when specimens of my size were mixed alternately, the best data was that the alignment of the body center positions was about ±0.8n on average, or it was impossible to align them all over the heat. According to the present invention, it can exhibit remarkable performance with an average of within ±0.30 under similar conditions, improve the insertion accuracy of automatic insertion machines, and improve the operating rate to 99.98% or more, which can be used in the industry. The profit improvement in this is significant.
