Cantilever feeder for PCB feeding system {Transfer device of cantilever type pcb suppling system}

The present invention relates to a cantilever feeding device for a PCB feeding system, and more particularly, to an improvement of a feeding device for feeding a PCB in order to supply it to another apparatus or device in an adsorbed or placed state.

In general, there are various kinds of PCB feeding apparatuses used in the PCB manufacturing line, and the means for conveying or feeding PCBs in such PCB feeding apparatuses also include adsorption means and various kinds of things, such as moving plates. It is used for the device.

The universal PCB feeder is installed on the side of the inspection apparatus, the printing apparatus, the reflow apparatus, or the component mounting apparatus to perform the function of drawing and loading or transporting the PCB which is supplied or discharged while the PCB is loaded.

In the prior art, as shown in Figure 7,

Sliding rails 4 are installed on the brackets 3 installed on the main frame 2 constituting the supply device 1 in a state parallel to the front, rear, left and right directions of the main frame 2, The transfer frame 6 having a PCB adsorbing means, which is composed of a plate member and the like coupled to the sliding block 5 and is capable of adsorbing the PCB to be supplied and withdrawn, is installed above the sulfide rail 4.

Drive means 7 are provided in one side direction of the transfer frame 6 (generally installed behind the supply apparatus so as to be inconspicuous), and both sides of the timing pulley 8 rotated by the drive means 7. Install on.

A timing belt 9 is connected between the timing pulleys 8 and the transfer frame 6 is fixed to the timing belt 9 so as to reciprocate by the driving means 7.

In the prior art as described above, since the slide rails for transporting are installed at the front and rear sides of the frame, the inside of the device cannot be easily checked, and the work for the maintenance of the device or the replacement of parts is not easy. Has

In addition, the operator should always be located at the front of the device to check the operating status of the device. In this process, an error of the device may occur and the operator may inflict physical injury by inserting his or her hand or arm into the device. This is high.

As mentioned above, the biggest problem of the prior art is that it is not easy to check the inside of the entire apparatus from the front side of the apparatus, and there are various problems such as a considerable difficulty in maintenance and the like.

Therefore, the present invention is designed to solve the problems described above, so that the transport frame of the supply device which is installed in the PCB manufacturing line and serves to supply and discharge the PCB can be transported while supporting it in a cantilevered form at the rear of the frame. The main purpose is to improve the transport structure to facilitate the internal check of the feeder on the front side of the frame as well as to provide ease of maintenance.

The cantilever feeding device 30 for the PCB feeding device to which the technology of the present invention is applied fixes the vertical frame 33 of the plate type in a vertical state to the rear side of the main frame 32 of the PCB feeding device 31.

The vertical frame 33 is fixed to the sliding block 34 by maintaining a predetermined interval on the upper, lower side, and the sliding block 34 is fixed to the sliding rail 35 coupled with the sliding block 34 on the back Join the plate 36.

Of course, in front of the transfer plate 36, a bracket or arm 40 for fixing the PCB feed port 39 composed of a suction plate for adsorbing the PCB and a cylinder 38 for lifting and lowering the suction plate is provided. It would be natural to protrude forward.

Both ends of the transfer plate 36 are fixed to the timing belt 41 using the fasteners 42, and the timing belt 41 is installed on the bracket 43 fixed to the main frame 32 at right angles. It is made to move by the timing pulley 46 provided in the drive shaft 45 of the motor 44 which rotates forward and reverse.

Both front sides of the timing pulley 46 are provided with guide rollers 47 and 48 which are also held by the brackets 43 so that the timing belt 41 can be moved more easily in the forward and reverse directions.

Fixing device 42 for fixing the timing belt 41 is formed by the guide groove 49 so that the timing belt 41 through the fixed to the transfer plate 36 by the fixing means 50, such as bolts Block 51 is provided.

On the outside of the fixed block 51 is fixed to the end of the timing belt 41 has a fixed block 51 and the control block 53, the interval is adjusted by the adjustment bolt 52 is provided with a timing belt 41 Configure to adjust the tension of

The present invention as described above,

PCB feed port 39 in front of the transfer plate 36 having a sliding rail 35 coupled to the sliding block 34 is fixed to the vertical frame 33 provided in a vertical state on the rear side of the main frame 32 Is installed.

In order to move the PCB feed port 39 in the left and right directions of the main frame 32, the motor 44 installed in the bracket 43 installed at right angles from the rear side of the main frame 32 is operated. Let's do it.

Then, the timing pulley 46 installed on the drive shaft 45 of the motor 44 rotates forward and backward, and the timing belt 41 installed on the timing pulley 46 passes through the guide rollers 47 and 48. By being in a fixed state at both ends of the transfer plate 36 is naturally the transfer plate 36 will be able to reciprocate in the left and right directions of the main frame (32).
