BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component supply apparatus, and in particular, in the semiconductor manufacturing process, the supply of electronic components stored in a tray allows the non-stop pallet to be safely clamped from the side to be supplied to the electronic component mounting apparatus. It is about a tray feeder.

BACKGROUND ART In general, an electronic component mounting apparatus (chip mounter) is used to automatically mount a component such as a semiconductor chip such as an integrated circuit (IC) or a high density integrated circuit, a diode, a capacitor, a resistor, or the like to a printed circuit board (PCB).

A tape feeder is disclosed as a technique for supplying miniaturized chip components to such a chip mounter.

The tape feeder described above is miniaturized and is easy and convenient for supplying chips of the same standard, but cannot be applied to supply of non-miniaturized and non-standardized parts.

Accordingly, a tray feeder has been disclosed as an apparatus for supplying a pallet for storing electronic components having different parts and different sizes in a tray partitioned into a matrix and mounting them to the chip mounter through a feeder arm.

Many such tray feeders are known in the art, and these tray feeders are known to be non-stop (NON-STOP) type and single type not according to replenishment or replacement of electronic components.

In the single method, a magazine containing stacked pallets on which a tray containing electronic components is stored is stored in an elevator moving up and down according to a ball screw driven by a motor, and moved to a predetermined position, and stored inside the magazine. A method of clamping pallets and supplying them to the chip mounter through a feeder arm. When all the electronic parts stored in the magazine are used, the surface mount technology stops the device to replace other electronic parts. The entire surface of the SMT line has to be stopped, resulting in a lot of inconvenience and inefficiency.

On the other hand, the non-stop system places the first and second elevators, each of which has several pallets mounted on the tray, so that the elevators arranged on the upper and lower sides can be independently moved. Means for elevating the first elevator up and down, and moving the electronic elevator to an electronic component take-off position and a refill or exchange position of the electronic elevator; When each of the first and second elevators is selected, the means for moving the electronic parts to the refilling or replacing position for refilling or replacing the electronic parts is provided. It is supposed to provide.

This non-stop method can provide a continuous supply of electronic components without stopping the operation of the tray feeder when replenishing or replacing the electronic components.

However, this tray feeder has a drawback in the process of taking out and transporting the pallet, which has been elevated to the withdrawal position, and frequently causes malfunctions in the working process, and the loss of time and workability that stops the entire line due to such malfunctions. There was

In particular, the pallet transfer method according to the related art is an example of a method of supplying the tray 10 to the feeder arm 30 by drawing the pallet 20 on which the tray 10 is placed, as shown in FIG. 1. The HOOK method is known.

The hook method is a hook 40 capable of dragging or pushing the pallet 20 stored in the magazine, and driven by the timing belt to transfer the desired pallet 20 toward the chip mounter. It is necessary to dig a hook-shaped withdrawal groove 21, and when the hook 40 passes between the withdrawal grooves 21 at the time of elevating, the desired pallet 20 comes to the feeding position and feeds to the feeder arm 30. It is supposed to be.

Accordingly, when the alignment between the pallets 20 is misaligned, a plurality of electronic components housed in the tray 10 by the hook 40 striking the pallets 20 during the elevatoring are separated out of the tray 10, thereby causing misalignment of the feeding process. There was an occurrence of work.

In addition, when conveying a heavy part during feeding, the hook 40 is distorted due to the moment of inertia caused by the pallet 20 and the weight of the part, and the hook is distorted during the elevation as mentioned above. As a disadvantage of hitting the pallet 20, there is a disadvantage in that misoperation is frequently generated and the continuity of the work falls.

In addition, the hook method is a method of dragging and pushing the pallet 20, and having a guide rail to support the pallet from the bottom when feeding, at this time, the noise due to friction with the guide rail in the conveying process of the pallet 20 There are many disadvantages, and the guide rail is worn by the pallet 20 little by little the phenomenon that periodic maintenance work is required.

On the other hand, the head of the chip mounter is generally set to the maximum distance that the head can move, the pallet mounting the tray within the maximum distance of the head should be transported.

In other words, the feeder arm 30 enters the chip mounter and enters the maximum motion distance portion of the head, and in this state, the head is picked and placed (PICK & PLACE). The hook method is the pallet 20. When the direction of the tray 10 placed in the horizontal direction is located in the horizontal direction, there is a disadvantage in that it is impossible to supply 1 to 2 rows of components, and when the direction of the tray 10 is located in the vertical direction, the chip mounter head There was a big disadvantage that the motion limit of the module did not reach the rows of three to five parts in the tray, so the parts in the last three to five rows could not be supplied.

In detail, referring to FIG. 1, the hook 40 is pulled and pushed through the withdrawal groove 21 of the pallet 20 on which the tray 10 is placed to supply materials. The position is located near the front of the pallet 20, and when the feeding is completed, the end of the feeder arm 30 and the end of the pallet 20 do not coincide, and the pallet 20 feeds the feeder arm 30. By being located inward from the end of the), the so-called dead zone (DEAD-ZONE) is present so that the movement area of the head of the chip mounter 1 to 2 rows of the last tray 10 out of the movement area of the chip mounter head. This results in a fatal drawback in that the head cannot pick up components belonging to the dead zone row.

This dead zone has a disadvantage in that the range of the dead zone is larger when the tray is located in the longitudinal direction as mentioned above.

In addition, the conventional tray feeder uses a rear pressure tray fixture 50 provided on one side to prevent movement during take-out and feeding process in which the tray 10 containing a plurality of electronic components is placed on the pallet 20. It is fixed by the elastic force of the leaf spring 51 provided in the front-end | tip.

In the conventional tray fixing method, since the tray 10 is fixed to the tray 10 only at the rear side, the tray 10 may not be prevented from moving to the side due to vibration or exercise force in the feeding process.

This movement of the tray 10 has resulted in the loss of work (LOSS) that must be stopped and corrected the entire line in the course of work.

In the conventional tray feeder, when replacing or replenishing electronic parts, the entire magazine is exhausted from the elevator and removed, and the pallet 20 having the new tray 10 placed therein is stacked again. In the course of work, a lot of labor is necessary, and there are disadvantages of inconvenience of work and the occurrence of safety accidents in the process of separating or combining magazines in the elevator.

The present invention has been created to effectively solve the above disadvantages of the prior art,

An object of the present invention is to control the forward and backward of the clamp by the pneumatic means in improving the clamping method according to the transfer of the pallet holding the tray on the basis of the non-stop tray parts supply device in a picking-up manner from the side Therefore, it is possible to provide a tray feeder that maximizes the reliability of the device by eliminating damages and malfunctions because the clamp does not hit the pallet away from the interference of the pallet where the clamp moves up and down during elevatoring.

(See an enlarged excerpt of FIGS. 11 and 12.)

13 to 16, the clamping means 410 is connected to the timing belt T / B of the belt driving means 450 and the sliding bearing 495 of the flow preventing guide means 490. A fixed base 420 to be assembled, a clamp 430 assembled from a forward and a backward material at an upper portion of the fixed base, and clamping a side surface of the pallet 160, and connecting the clamp to the air control means 500. And a plurality of compression springs 445 for clamping the pallet 160 by advancing the clamp 430 in conjunction with the operation of the cylinder.

In this case, the fixing base 420 and the clamp 430 are protruding walls 431 protruding from the lower portion of the clamp 430 between the partition walls 421 protruding both the front and rear sides of the fixing base 420. As the forward and backward movements are restricted and seated, the front and rear partition walls 421 have guide rods 422 and 422 assembled therebetween in a horizontal direction, respectively, and protruding walls 431 of the clamp 430 to the guide rods. It is fitted into the sliding bearings (432, 432) seated on the) to prevent separation from each other.

In addition, each of the plurality of springs 445 is interposed between the protruding wall 431 and the spring support 423 assembled to the fixed base 420.

The cylinder 440 is assembled to the fixed base 420 in a state where the tip of the rod 441 is in contact with the support wall 433 which is blocked at the center of the clamp 430.

The fixed base 420 is assembled with a holder 411 to protect the connection hose 444, one side of which is connected to the port 442 of the cylinder at the bottom, the front of the holder of the connection hose 444 Connecting to the other side and the connection port 412 connected to the fixed connector 510 of the air control means 500 is assembled, connected to the timing belt (T / B) of the belt driving means 450 and prevents the flow The belt fixing plate 413 assembled with the sliding bearing 495 of the guide means 490 is assembled.

In addition, the clamp 430 is assembled with the leaf spring-shaped clamp spring 435, the front end of which is bent upwards on both sides of the front and the front of the clamp 430 and the clamp spring 435 between the pallet ( The side of 160 is inserted and clamped in the form of tongs.

The clamp spring 435 is configured to clamp and support the side surface of the pallet 160 safely and firmly at the upper side when the clamp 430 moves forward and lowers the side surface of the pallet 160.

Referring to FIGS. 10 to 12, the operation of the clamping means 410, as mentioned above, is selected from among the first and second elevators 330 and 350 by a programmed controller (not shown). Or 350 is positioned for elevation.

During this elevator operation, air (compression) is applied to the cylinder 440 by the operation of the valve 520 through the connection port 412 of the clamping means 410 connected to the fixed connector 510 of the air control means 500. Air) is supplied to the rod 441 of the cylinder 440 to advance and push the support wall 433 of the clamp 430.

In this case, the thrust of the cylinder 440 is greater than the elastic force of the plurality of springs 445, thereby forcibly retracting the clamp 430 to always move forward, and stopping the elevator operation, that is, setting the pallet 160 When the c) is elevated to the feeding position and stops, the compressed air in the cylinder 440 is removed by the air control means 500.

Accordingly, the clamp 430 advances again with the elastic force of the plurality of springs 445 to clamp the side surface of the pallet 160 accommodated in the magazine 200 or 250 with the support of the clamp spring 435. At the same time, as described above, the belt driving means 450 is transferred to the tip of the feeder arm 400 to supply electronic components to the chip mounter.

In this way, after the electronic component is supplied to the chip mounter, the pallet 160 is returned and positioned again, and this operation is performed by the reverse operation of the belt driving means 450, thereby shifting the clamping means 410 toward the base 100. As described above with respect to the operation of the belt driving means 450 to be returned, a detailed description thereof will be omitted.

In this way, the clamping means 410 moved to the feeding position is returned to a state in which the connector 412 is connected to the fixed connector 510 of the air control means 500 again.

In this way, when the clamping means 410 is returned to the partitioned partition layer of the magazine 200 or 250, the pallet 160 (the electronic parts having the exhausted trays) clamped to the clamp 430 is returned. It is in a state positioned at 240.

When the control unit (not shown) recognizes such a state, the valve 520 of the air control unit 500 operates to supply air to the cylinder 440 as described above to reversely operate the clamp 430. The clamping state is released.

When the operation is completed, the first elevator 300 or the second elevator 350 equipped with the magazine 200 or 250 is elevated to feed a new pallet 160 on which the tray 150 containing the electronic components is placed. Position it.

Therefore, in this operation, the lifting portion of the elevator 300 or 350 in the state where the clamp 430 of the clamping means 410 is retreatly positioned is formed between the inside of the elevator and the outside of the magazine 200 or 250. Since it is made in the magazine (200, 250) without the collision with the safe elevator.

In this way, when the pallet 160 to be fed is placed and the operation of the elevator 300 or 350 is stopped, the pallet 160 is opened on the side surface of the magazine 200 or 250 by the repeating operation as described above (penetrating from the outside to the inside). Easily clamped and transported through the blown out hole 241, or the returned pallet 160 is stored in the magazine 200 or 250 by a return operation, and a new one (with a tray containing electronic components mounted thereon). It is transferred by clamping.

The pallet 160 allows the tray 150 to be mounted by cutting and bending the plate-shaped material (aluminum) for the purpose of lightening and simplifying the construction, and thus the clamp 430 of the clamping means 410. ) And the side surface of the pallet 160 to feed, the clamp on both sides of the pallet 160, that is to say in the ejection hole 241 of the magazine (200, 250) for the safety of the conveyance 430 is configured by screwing the support clamper 161 that is inserted between the front end and the clamp spring 435.

The tray 150 mounted on the pallet 160 is provided with a local adsorption fixture 600 of the removable material for the purpose of solidity in the pallet 160 and space utilization according to the mounting direction.

As shown in FIGS. 18A to 18C, the local adsorption fixture 600 includes a support including a guide groove 620 narrowly formed upward and an axis lead hole 630 vertically penetrated with the guide groove ( 610, a suction plate 640 that passes through the shaft outlet hole 620, and the suction shaft 650 protruding from the upper portion, and is seated in the guide groove 620, and the traction shaft 650 and the shaft 670. It was composed of a lever 660 coupled to.

At this time, the support 610 is formed with a tapered surface 610a in which the outer circumferential surface of the vertical direction is inclined downward, and the exhaust hole 680 is communicated with the guide groove 620 in the vertical direction.

As shown in FIGS. 19A and 19B, the local adsorption fixture 600 may be fixed to the side surfaces of the tray 150 in a direction, length direction, and width direction thereof to firmly and securely fix the tray 150.

In the installation process of the local adsorption fixture 600, the worker presses the tapered surface 610a of the support 610 on the side in the state where the tray 150 is mounted on the pallet 160 as shown in the drawing. When the lower suction plate 640 is in close contact with the pallet 160 and the lever 660 is bent in the horizontal direction about the shaft 670, the suction plate 640 is pulled upward by the traction shaft 650. The vacuum pressure is generated on the inner surface while being in close contact with the guide groove 620 to be securely fixed in the form of pressing the side direction of the tray 150 as a fixed state to the pallet 160 (see FIG. 18C).
