Description

An apparatus for feeding the plug pin its inserting the PCB plate

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plug pin conveying apparatus inserted into a PCB electromagnetic plate. Specifically, a plug pin conveyed by transferring a plug pin through a hose using air from a pin supply unit is used as a vacuum absorber. The present invention relates to a plug pin transfer device for inserting a set plug pin into a mounting position of a PCB board after suction and setting.

In the transfer apparatus for inserting a plug pin into a conventional PCB substrate, as shown in Fig. 5, a standby portion 1 is provided for waiting for the plug pin 6 to be inserted into the PCB substrate, and this standby portion 1 The supply pins (2) for supplying the plug pins (6) to the hook 31 of the transfer section (3) through the aero hose 21 by separating the plug pins (6) supplied at regular intervals from one by one, 2) and the fastening pipe 311 which is inclined to be connected to the hose 21 to guide the pin 6, and the V-groove 312 for seating the plug pin 6 guided by the fastening pipe 311 The formed hook 31 is installed at the bottom, the sensor for detecting the seating of the pin 6 in the v-groove 312 of the hook 31, and slides up and down by the cylinder (5) and the pin (6) It consists of the conveying part 3 in which the adsorption | suction machine 32 for suctioning | sucking a vacuum by the vacuum generator 321 is provided.

FIG. 6 shows a side view of a conventional conveying device in which the plug pin 6 which is guided obliquely from the fastening pipe 311 is seated in the v groove 312 of the hook 31.

FIG. 7 illustrates a main view of the transfer part in FIG. 5, wherein the transfer part detects a hook 31 seating the plug pin 6 and a plug pin 6 seated on the left and right sides of the hook 31. 33) and a detachable part that is opened around the hinge 341 when the plug pin 6 adsorbed to the absorber 32 and the absorber 32 suctioning the plug pin 6 by vacuum are inserted into the PCB substrate 4. A spring 342 is provided on one side so as to give restoring force to the 34 and the detachable part 34.

In the conventional plug pin feeder configured as described above, the plug pins 6 supplied at regular intervals from the plug pin standby unit 1 are separated from the supply unit 2 one by one, and then the air transfer unit 3 is connected through the hose 21. Is supplied. The plug pin 6 supplied to the transfer part 3 through the hose 21 is seated in the V groove 312 of the hook 31 installed at the lower end of the transfer part 3 via the fastening pipe 311, and the hook 31. The plug pin 6 seated in the V-groove 312 of) is checked to be seated correctly by the sensor 33. When the seat pin is correctly seated, the adsorber is controlled according to the control of a computer that receives the signal of the sensor 33. As the 32 generates a vacuum and descends, the plug pin 6 is sucked into the adsorber 32 and moved to the PCB substrate 4, whereby the detachable portion 34 is opened and the substrate 4 is set. The plug pin 6 is inserted into the hole 41 and is returned to its original position by the restoring force of the spring 342.

However, in such a conventional plug pin transfer device, the plug pin 6 conveyed through the pin supply unit 2 is crushed or has a poor tolerance for size, or the transfer unit when the hook 31 is worn or not set correctly. (3) The hook 31 at the lower end may not be seated correctly in the groove 312 or may not stand vertically and may be inclined, resulting in a high defect rate, and the plug pin 6 may have a groove in the hook 31. If the inclined to the 312, the adsorber 32 is advancing and sucked in a vacuum is not well sucked, and even if sucked into the adsorber 32 is inserted into the substrate 4 when the hole in the PCB (4) ( 41 is not inserted into the substrate (4) is broken, the transfer part 3 is provided with a spring 342 only on one side, the wear of the hook 31 occurs a problem that is difficult to set, and the adsorber (32) )Wow Since the distance of the hook 31 is far, there was a serious problem of noise due to the lowering of the adsorber 32.

The present invention is to improve the conventional problems as described above by reducing the insertion speed and noise by inserting the plug pin transferred from the supply directly into the vacuum in the adsorber, the pin pin transfer device that can be accurately inserted into the PCB substrate The purpose is to provide.

Another object of the present invention is to install the springs on both sides of the center of the conveying part to make the setting accurate and to prevent uneven wear of the device.

In order to achieve the above object, the present invention provides the plug pin 6 to the hook 31 by the supply unit 2 through the hose 21 from the standby unit 1, the plug pin 6 In the vacuum suction device 321 is provided with a conveying unit 3 configured to suck the vacuum and the adsorber 32 is able to slide up and down by the cylinder (5),

Sensors 33 for detecting the plug pins 6 are formed on the left and right sides of the adsorber 32, and the plug pins 6 are inserted into the PCB board 4 by an operation signal of the computer by the sensor 33. Detachable portion 34 is provided with a central opening about the hinge 341, the lower end of the hook portion 31 of the detachable portion 34, the pin suction hole communicating with the adsorber 32 and the hose 21 ( 31A) is formed, and the springs 342 are installed on both sides of the transfer part 3.
