Description

High-capacity metering dispenser head for precise control of up-down and rotation {A DISPENSER HEAD ABLE TO CONTROL A ROTATION AND UP-DOWN OF A POSTON IN A HIGH-SPEED, FIXED-AMOUNT, PRECISE DISCHARGE TYPE}

The present invention dispenses an adhesive for fixing a component such as a chip or an IC on a printed circuit board (PCB) used in home appliances such as TVs, VTRs, telephones, modems, and communication devices. The dispenser head, more specifically, the dispensing function of up / down and rotation due to dotting of epoxy is built in a single body, so that the weight and weight of the basic elements that the high-speed equipment should be equipped with Maximizing the dotting work, minimizing the epoxy dotting amount and minimizing the defective rate of the dotting epoxy by quantitative discharging, thereby maximizing the reliability of the device and selecting the required quantity by adopting the manifold structure. It can be assembled and used in the It relates to a high-speed mill control the dispensing-type dispenser head as possible.

Recently, in response to the trend of miniaturization of electrical and electronic products, electronic components have become smaller, higher in density, and more diversified.

Therefore, surface mounting technology has been commercialized as a radix applied to assembly production of a printed circuit board (PCB) applied to such electrical and electronic products.

Surface Mount Technology (SMT) is classified into the development of Surface Mounting Device (SMD) and the development of assembly technology of such surface mounting component.

The surface mount parts described above have been developed to miniaturization due to high integration based on the rapid development of semiconductor technology, and the development of surface mounters has also been accelerated to mount such miniaturized parts.

Such a surface mounter is a device for mounting surface mount components (chips, ICs) on a PCB. The surface mounter is a device for supplying surface mount components from a feeder and transferring them to a mounting position on the PCB.

In such surface mounting, a process of applying an adhesive such as epoxy on the PCB on which the surface mounting component is located is required by a dispensing process.

Recently, the surface mounter has been developed and commercialized with a high-speed chip mounter of 65,000 Chip / H or more, it is required a high-speed dispensing equipment corresponding to this chip mounter.

This epoxy dispensing process must ensure accuracy and rapidity, and the dispensing of a certain amount of epoxy according to the dispensing, and the precise dispensing in the right place automatically and accurately.

However, the conventional dispensing method has a disadvantage in that the weight and volume of the entire head are excessively increased due to mechanical mechanisms and a large number of constituent members because the independent heads must be controlled separately, and the moving inertia due to dispensing increases. Inevitably, the speed reduction and motor capacity had to be increased.

Therefore, the Z-axis (up and down) movement according to the dispensing of epoxy (EP) causes the head 1 to be repeatedly raised and lowered by the repetition of the lifting / lowering operation of the robot unit. When dispensing two dogs, the robot unit's Z axis must be reciprocated 100 times, which results in slow reaction speed and poor workability.

In addition, in order to change the dispensing position, that is, to switch the dotting position, when the rotation of the head 1 is required, only the entire rotation of the robot unit is possible, which results in an excessive work time.

In particular, since the dispensing is performed after the head 1 is lowered and the flowability of the epoxy is always directed to the downward direction of the nozzle 2, it is necessary to wait until the end of the flowability of the epoxy to provide stable dotting, which requires a lot of dotting time. When the upward movement for the next dotting proceeds from the point when the fluidity is not finished, the tail (Tail) appeared severely and there was a disadvantage in that it is difficult to discharge the fixed flow rate.

The present invention has been researched and developed to solve the disadvantages of the prior art as described above,

This operation of the present invention will be described in detail below with reference to FIGS. 28A to 28J.

As described above, in the present invention, the module plate 100 is interposed between the X-axis and the Y-axis at the upper portion of the PCB substrate PB which is transferred and positioned while assembled in a conventional robot unit (not shown). It is installed to move freely in the control state.

In this state, air supply means for supplying compressed air to one side of the air supply path 140 of the module plate 100, for example, a compressor is connected, and the other end of the end cap (not shown) is finished.

When power is applied to the valve means 800 in this state, the valve means 800 is a cylinder via the air passage 290 of the head body 200 through the front air discharge / inlet hole 810 The compressed air introduced into the lower chamber of the chamber 210 lifts up the piston 320 installed in the lower chamber of the cylinder chamber 210 so that the up-down rotation means 300, the dotting nozzle means 400, and the discharge amount adjusting means. Z-axis movement is made to simultaneously raise (600).

Looking at this process in more detail, if the piston 320 of the up-down rotation means 300 is raised by the air pressure, the up-download 310 is raised, screwed up and down joint 350, this up-down The ball spline shaft 380 assembled with the joint is forced to raise the elastic force of the compression spring 360 while being prevented from rotating by the ball spline bearing 381.

At this time, the air filled in the central chamber of the cylinder chamber 310 is discharged through the exhaust hole 220 connected to the front upper portion of the head body 200 is stepped head 312 of the up-downloading 310 Smooth ascending operation is provided without internal air compression.

In connection with such an operation, the dotting nozzle means 400 assembled to the lower connection rod 311 of the up-downloading 310 is also raised at the same time.

That is, the connecting rod 311 and the screw connection joint 410, the guide block 420, the nozzle assembly 430, the nozzle cap 440 is raised in an integrated concept.

As the rising of the dotting nozzle means 400 proceeds, the discharge amount adjusting means 600 installed in the up-down rotation means 300 rises together with the dotting nozzle means 400 with a predetermined time difference.

That is, the dotting piston 610 of the discharge amount adjusting means 600 is a compression of the piston head 670 in the center of the piston hole 315 of the up-downloading 310 is inserted between the up and down joints 350, Receiving a downward resilience force by the spring 620 through the bottom of the dotting needle 612 through the filling hole 412 of the connection joint 410 to maintain a fine gap with the needle seat 433 of the nozzle assembly 430 Since the dotting nozzle means 400 has a short time difference, the dotting needle 612 of the dotting piston 610 of the discharge amount adjusting means 600 is brought into contact with the seat surface of the needle sheet 433. While rising to the state is to rise while compressing the compression spring (620).

At this time, the dotting needle 612 of the dotting piston 610 is raised to a seating state in contact with the needle sheet 433 to close the nozzle hole 432 of the nozzle assembly 430.

In this state, the epoxy (EP) filled in the syringe (SL) of the epoxy conveying means 500 is compressed by a plunger (not shown) which is compressed by a constant pressure (usually 0.5-2 bar) and is connected to the hose. Through the filling guide hole 422 of the guide block 420 of the dotting nozzle means 400 through the 540 is supplied to the filling hole 412 therein.

That is, the epoxy (EP) transferred to the filling guide hole 422 is guided to the filling guide groove 413 of the connection joint 410 and filled into the filling hole 412 through the filling inlet hole 414. Ascending to the state as shown in Figure 28a.

The lowering force of the Z axis starts with the repulsive force of.

That is, the compression spring 360 of the up-down rotation means 300 and the compression spring 620 of the discharge amount adjusting means 600, which are compressed by the air pressure, are extended to extend the up-downloading 310, the piston 320, The up-down joint 350, the ball spline shaft 380 and the dotting piston 610 are simultaneously lowered, and the dotting nozzle means 400 assembled to the up-downloading 310 is connected to the lower surface of the head body 200. Spaced apart via the state of FIG. 28B.

In this way, the up-down rotating means 300, the discharge amount adjusting means 600 and the dotting nozzle means 400 are lowered, and the lower dotting needle formed at the lower end of the dotting piston 610 of the discharge amount adjusting means 600 ( 612 is spaced apart from the needle seat 433 of the dotting nozzle means 400, the epoxy (EP) filled in the filling hole 412 is introduced into the nozzle hole 432 (see Fig. 28c).

Thus, the epoxy (EP) is filled in the nozzle hole 432 through a gap (GAP) spaced between the dotting needle 612 and the needle seat 433 in the state filled up to the inner bottom of the nozzle 435 of the lower While descending, the lowering by the stopper 436 is limited, thereby completing the Z-axis lowering operation of dotting the PCB substrate PB (see FIG. 28D).
