Description

Loading element for loading electronic components {LOADING ELEMENT FOR LOADING ELECTRONIC DEVICE}

The present invention relates to an electronic component moving device that grips and moves electronic components.

Electronic components such as SSD (Solid State Drive) are produced and then loaded onto process trays. Then, the electronic components loaded on the process tray are moved to the test tray for testing. The first test process for the electronic component is performed by electrically connecting the electronic component to the tester while loaded on the test tray.

Electronic components determined to be good products in the first test process are completed as shipped products through the casing process and labeling process, and then the second test process is performed. After the second test process, electronic components are classified into good and defective products according to the test results, and only good products are shipped.

Previously, the above series of processes, excluding the testing process, were performed manually, resulting in low productivity. Accordingly, the applicant of the present invention has, prior to the present invention, a labeling equipment capable of performing a casing process and a labeling process for electronic components (Korean Application No. 10-2014-0041140, hereinafter referred to as 'prior invention 1'), labeling Test equipment for performing a second test process on completed electronic components (Korean Application No. 10-2014-0091798, hereinafter referred to as 'Prior Invention 2'), classifying electronic components for which the second test has been completed according to test results An electronic parts sorting equipment (Korea Application No. 10-2014-0154576, hereinafter referred to as ‘Prior Invention 3’) has been proposed.

Prior invention 1 is a technology related to equipment for performing casing work and labeling work on electronic components determined to be non-defective after the first test process.

Prior invention 2 is a technology related to equipment for performing a second test process on electronic components for which casing work and labeling work have been completed.

Prior invention 3 is a technology related to equipment for classifying electronic components according to test results after the second test process.

In addition, the applicant of the present invention forms a system with the equipment according to the above prior inventions 1 to 3, and provides a device for loading the electronic components loaded on the process tray onto the test tray in order to perform the first test process. The equipment (Korean Application No. 10-2014-0190964, hereinafter referred to as ‘Prior Invention 4’) has been proposed.

And when the first test is performed by the tester after the electronic components are loaded on the test tray by the electronic component loading equipment according to prior invention 4, equipment for unloading the electronic components from the test tray and loading them into the underfill jig (Republic of Korea) Application No. 10-2015-0015600, hereinafter referred to as ‘Prior Invention 5’) was also proposed. For reference, when the work using the equipment according to prior invention 5 is completed, the underfill jig loaded with electronic components is provided as the equipment according to prior invention 1.

Meanwhile, the various trays applied to the above prior inventions may have a configuration that locks the electronic components to prevent the loaded electronic components from leaving, if necessary. Of course, the loading elements other than the various trays introduced in the above prior inventions may also be provided with a configuration for locking flat electronic components such as SD to load them in an upright position. If the loading element is equipped with a configuration to prevent the electronic component from being separated, the lock state of the electronic component must be released in order to move the electronic component.

However, when unlocking an electronic component, there is a risk that the electronic component may be separated due to impact caused by unlocking. And when electronic components are separated, the operation rate decreases due to the loss of electronic components and the shutdown of all equipment due to jams.

The present invention is related to the movement of electronic components and has the following purposes.

First, it provides a technology to prevent the electronic components from being separated from the loading element due to the release impact when unlocking the electronic components loaded on the loading element.

Second, it provides a technology that can prevent the deviation of electronic components of various specifications without separate replacement of parts or changes in settings.

An electronic component moving device according to the present invention for achieving the above object includes an electronic component picking device that grips or releases electronic components loaded on a loading element in a locked state to prevent separation; a lock unlocker that unlocks the electronic component that must be moved while being held by the electronic component picking machine; a separation prevention device that prevents the electronic components from being separated due to a release impact when the lock state is released by the unlocker; and a horizontal mover that moves the electronic component picking device in a horizontal direction; Includes.

The separation prevention device includes: a pressing member that presses the electronic component downward to prevent the electronic component from being thrown out; and a rising source that raises the pressing member; Includes.

The rising source provides the lifting force necessary to raise the pressing member, and the pressing member is lowered by its own weight, so that the end position of the lowering of the pressing member is determined by the height of the top of the electronic component.

The rising source includes: a lifting block that is provided to be capable of being raised and lowered and raises the pressing member when rising; and a cylinder for elevating the elevating block; It includes, and the pressing member descends by its own weight when the lifting block descends.

According to the present invention, the following effects are achieved.

First, the reliability of the equipment is improved because there is no risk of the electronic components being separated even if a release shock occurs when the electronic components loaded on the loading element are unlocked.

Second, because it is possible to prevent deviation of electronic components of various specifications without separate replacement of parts or changes in settings, it reduces production costs and increases operation rate.

<Description of loading elements>

First, a loading element with a locking structure to prevent electronic components from being separated will be described.

FIG. 1 is a perspective view of a tray (T), which is one of the loading elements, and FIG. 2 is a schematic cross-sectional view of a loading module (LM) applied to the tray (T) of FIG. 1.

The tray (T) of FIG. 1 is provided with a plurality of loading modules (LM) as shown in FIG. 2.

The loading module LM has an insertion groove (IS) into which the electronic component (ED) can be inserted, and the insertion groove (IS) opens upward. This loading module (LM) has a lock (10) and a release pin (20).

The lock 10 is provided to lock the lower end of the electronic component ED inserted into the insertion groove IS, and is composed of a lock lever 11 and a spring 12.

The locking lever 11 is provided to be rotatable, and its inner end is maintained inserted into the locking groove LI formed in the electronic component ED by the spring 12.

The spring 12 provides elastic force to maintain the inner end of the locking lever 11 inserted into the locking groove (LI) formed in the electronic component (ED).

The release pin 20 is provided to be lifted up and down, and receives an upward elastic force by the elastic member 21. When the release pin 20 is lowered by an external force, the lower end of the release pin 20 can force the lock lever 11 to rotate by pressing the outer end of the lock lever 11. When the lock lever 11 is forcibly rotated by the release pin 20, the lock state of the electronic component ED is released by the lock 10, as shown in FIG. 3. Of course, the electronic component (ED) can be extracted from the insertion groove (IS) of the loading module (LM) only when the lock state is released as shown in FIG. 3 .

Meanwhile, as shown in FIG. 4 , electronic components ED ₁ and ED ₂ of various specifications having different lengths in the vertical direction may be mounted on the loading module LM. Therefore, when trying to move an electronic component (ED), the standard of the electronic component (ED) is also an important factor to consider.

<Description of electronic component moving device>

FIG. 5 shows an electronic component moving device 500 (hereinafter abbreviated as 'moving device') according to an embodiment of the present invention for moving electronic components (ED) loaded on a loading element such as the tray (T) of FIG. 1. This is a schematic perspective view of .

The moving device 500 includes an electronic component picking device 510, a locking device 520, a separation prevention device 530, a horizontal moving device 540, and a rotating device 550. For reference, some of the components that make up the mobile device 500 may be hidden in each drawing due to limitations in illustration, so for convenience, only components that can be shown in the drawings will be described using symbols.

As shown in the excerpt of FIG. 6, the electronic component picking machine 510 includes four grip levers 511a to 511d, a gap adjustment circle 512, and two lift circles 513a and 513b.

The four grip levers 511a to 511d are provided to be movable in the left and right directions, and the two on the left and right are paired and face each other in correspondence. The moving device 500 according to this embodiment has a total of two electronic components (ED) because the two paired grip levers (511a and 511c / 511b and 511d) grip or release one electronic component (ED) ED) can be grasped or released. Additionally, each of the grip levers 511a to 511d includes a moving member (ME), a gripping member (GE), and an adjustment element (SD).

The moving member (ME) moves in the left and right directions according to the operation of the gap adjustment source 512.

The gripping member (GE) is coupled to the moving member (ME) so that it can move in the left and right directions, and grips or releases the electronic component (ED).

The adjustment element (SD) moves the gripping member (GE) in the left and right directions and may be provided as a cylinder. These adjustment elements (SD) move the gripping members (GE) independently, so that the front and rear gripping members (GE), which are provided in pairs, independently grip the electronic component (ED) or Allows the phage to be released. That is, as shown in FIG. 6, only the adjustment elements (SD) on the front (or rear) side operate, so that only the grip members (GE) on the front (or rear) side can grip or release the electronic component (ED). There is.

The gap adjustment circle 512 includes a motor 512a, a rotating rod 512b, and a pair of coupling blocks 512c-1 and 512c-2.

The motor 512a is provided to rotate the rotating rod 512b forward and backward.

The rotating rod 512b rotates forward and backward according to the operation of the motor 512a, and is screw-coupled with a pair of coupling blocks 512c-1 and 512c-2, respectively. Since this rotating rod (512b) has screw threads formed in different directions left and right relative to the center in the longitudinal direction, when the rotating rod (512b) rotates, both coupling blocks (512c-1, 512c-2) They are made to widen or narrow each other.

A pair of coupling blocks (512c-1, 512c-2) are screwed to the rotating rod (512b) so that they can be moved in the left and right directions. Therefore, as the rotating rod 512b rotates, the pair of coupling blocks 512c-1 and 512c-2 move in the left and right directions. A rail (R) and a rail block (B) are placed on each of these pair of coupling blocks (512c-1, 512c-2), and a moving member (ME) is coupled to be capable of being raised and lowered.

For reference, the first screw grain for screw coupling between the rotating rod (512b) and the first coupling block (513c-1) and the second screw grain for screw coupling between the rotating rod (512b) and the second coupling block (513c-2) are Since they are formed in opposite directions, when the rotating rod 512b rotates, the pair of coupling blocks 512c-1 and 512c-2 move in opposite directions.

In addition, among the pair of coupling blocks (512c-1, 512c-2), the first coupling block (512c-1) on the left is coupled with the moving member (ME) on the first grip lever (511a, 511b) on the left. and the second coupling block (512c-2) on the right is coupled with the moving member (ME) on the second grip levers (511c, 511d) on the right. Therefore, when the first coupling block (512c-1) and the second coupling block (512c-2) move in the left and right direction, the first grip levers (511a, 511b) and the second grip levers (511c, 511d) also move in the left and right directions. It moves.

Two lifting sources 513a and 513b are provided to raise and lower the grip levers 511a to 511d. These two lifting sources (513a, 513b) may be provided as cylinders and are coupled to the installation plate (A).

The first hoisting member 513a lifts the two grip levers 511a and 511c at the front, and the second hoisting member 513b lifts the two grip levers 511c and 511d at the rear.

The lock releaser 520 unlocks the electronic component ED that must be moved while being held by the electronic component picking device 510. That is, the lock release device 520 presses the release pin 20 on the loading module LM of the tray T downward to unlock the electronic component ED. To this end, the lock release device 520 includes two release members 521a and 521b and two release sources 522a and 522b, as shown in the excerpt of FIG. 7 .

The two release members 521a and 521b, respectively provided on the left and right, have release ends FE that protrude in the front and rear directions, respectively.

Among the two release sources 522a and 522b, the first release source 522a raises and lowers the first release member 521a, and the second release source 552b raises and lowers the second release member 521b. These release sources 522a and 522b may be provided as cylinders. And the release sources 522a and 522b are coupled to the moving member ME by the engaging member JE.

The separation prevention device 530 prevents the electronic component ED from jumping out due to the release shock applied by the rotational force of the lock lever 11 when the lock state is released by the lock release device 520. To this end, the separation prevention device 530 includes a pressing member 531, a guider 532, and a rising source 533, as shown in the excerpt of FIG. 8.

The pressing member 531 is provided to be able to move up and down, and pressurizes the electronic component (ED) downward to prevent the electronic component (ED) from bouncing upward. This pressing member 531 presses the front pressing end (PE ₁ ) to press the electronic component (ED) in the front loading module (LM) and the electronic component (ED) in the rear loading module (LM). It has a rear pressing end (PE ₂ ) to do this. That is, the front pressing end (PE ₁ ) and the rear pressing end (PE ₂ ) each have a horseshoe shape extending downward from the front and rear ends of the long upper portion 531a in the horizontal direction. And the pressing member 531 has a stopping bar 531b extending upward from the upper part 531a. The upward movement of the pressing member 531 occurs at the rising source 533, but the downward movement of the pressing member 531 occurs due to a natural fall due to its own weight.

For reference, depending on the implementation, the pressing member 531 may be provided with a spring rather than a free fall structure to elastically support the pressing member downward by elastic force. However, in this case, the compression rate of the elastic member varies depending on the length of the electronic component. It varies, and the elasticity varies depending on the compression ratio. Therefore, in the case of electronic components that are too long, they may not actually bounce up. In other words, the free-fall structure due to the self-weight of the pressing member 531 adopted in this embodiment is more preferable than the spring structure.

The guider 532 guides the raising and lowering of the pressing member 531 and may be provided as a ball bush.

The rising source 533 provides the necessary lifting force to raise the lowered pressing member 531. This rising source 533 includes a lifting block 533a, a cylinder 533b, a locking member 533c, and a coupling table 533d.

The lifting block 533a is lifted and lowered by the cylinder 533b. This lifting block 533a is installed to cross the lower side of the upper part 531a of the press member 531, which has a horseshoe shape opening downward. Here, the lifting block 533a and the upper part 531a of the pressing member 531 do not contact each other due to the stopping member 533c, which will be described later. Therefore, even when the pressing member 531 freely falls or the lifting block 533a rises, contact shock cannot occur between the lifting block 533a and the pressing member 531.

The cylinder 533b is provided as a driving source to raise and lower the lifting block 533a.

The locking member 533c is provided to be lifted up and down while being guided by a guide rod (GR), and when rising, the pressing member 531 can be raised together by hanging the upper end of the locking bar 531b provided on the pressurizing member 531. make it possible At this time, the guider 532 coupled to the locking member 533c is placed so that the upper end of the locking rod 531b is caught by the locking member 533c. Accordingly, when the locking member 531 rises, the pressing member 531 also rises, so no contact collision occurs between the upper part 531a of the pressing member 531 and the lifting block 533a. Since the upper part 531a of the pressing member 531 and the lifting block 533a are maintained spaced apart from each other, the generation of particles or vibrations due to mutual collision or friction can be prevented. Of course, it can also be considered possible for the lifting block 533a to be configured to contact the upper part 531a of the pressing member 531.

The coupling table 533d couples the locking member 533c to the lifting block 533a. Therefore, when the cylinder 533b operates, the lifting block 533a, the stopping member 533c, and the coupling table 533d rise or fall together.

For reference, Figure 9(a) shows a state in which the cylinder 533b lowers the lifting block 533a, and Figure 9(b) shows the pressing member 531 as the lifting block 533a is lowered. It shows a lowered state. Of course, when the lifting block 533a is lowered in the state of Figure 9 (a), the pressing member 531 is also lowered almost simultaneously. However, to explain that the lifting block 533a and the pressing member 531 are lowered independently of each other, For convenience, it is shown in (a) of FIG. 9 that the pressurizing member 531 has not yet been lowered.

And the separation prevention device 530 is coupled to the hoisting source (513a, 513b) by placing a coupling plate (JP).

The horizontal mover 540 moves the electronic component picking machine 510 in the horizontal direction. Of course, depending on implementation, two horizontal movers may be provided for left-right movement and forward-backward movement.

As shown in FIG. 5 , the rotator 550 is provided to rotate the electronic component picking machine 510 using the vertical line PL as a rotation axis. Accordingly, the electronic component ED held by the electronic component picking machine 510 can be placed in a state rotated by an arbitrary angle.

Next, the operation of the electronic component moving device 500 configured as above will be described with reference to the operating states of the main parts shown in FIGS. 10 to 15. Here, for brevity of explanation, the description is made with reference to the front view, so the configurations on the rear side were naturally not expressed in the drawing.

First, as shown in FIG. 10, the horizontal mover 540 operates to position the electronic component picking machine 510 above the electronic component ED.

In the state shown in FIG. 10, the lifting source 513a operates to lower the grip levers 511a and 511c, and the separation prevention device 530 operates to lower the lifting block 533a, resulting in the state shown in FIG. 11. At this time, the operation of the hoisting source 513a and the operation of the separation prevention device 530 may be performed simultaneously, or one operation may be performed first. Of course, when the lifting block 533a is lowered by the operation of the separation prevention device 530, the pressurizing member 531, which has no elements preventing it from falling, also falls due to free fall due to its own weight. At this time, the lowering end position of the pressing member 531 is determined by the top height (H) of the electronic component (ED). That is, as compared in (a) and (b) of Figure 12, since the cylinder 533b is provided in the rising source 533, the lowering height (h) of the lifting block 533a is constant, but the electronic component ( It can be seen that due to the difference in the upper and lower lengths (ED, ED'), the lowering end positions (H ₁ , H ₂ ) of the pressing member 531 are different. In this way, since the lowering end position of the pressing member 531 can be naturally determined according to the specifications of the electronic component (ED), there is no need for the manager to replace parts to adjust the lowering ending position of the pressing member 531. If considering raising and lowering the pressurizing member by a motor, the operating amount of the motor must be set after stopping the operation of the equipment in order to adjust the lifting amount of the pressurizing member. However, according to this embodiment, although the cylinder 533b, which is inexpensive, is used, the lowering end position of the pressing member 531 is naturally determined by the top height of the electronic component (ED), so the lowering ending position of the pressing member 531 is determined naturally. You don't have any hassle to set it up.

In the state shown in FIG. 11, the gap adjuster 512 operates to narrow the gap between the grip levers 511a and 511c, thereby creating the state shown in FIG. 13. And in the state of FIG. 13, the lock release device 520 operates to lower the release members 521a and 521b, so that the release members 521a and 521b press the release pin 20 to rotate the lock lever 11. As referenced in 14, the lock state of the electronic component (ED) is released. At this time, as the lock lever 11 rotates, the electronic component (ED) may be raised by receiving force upward, but since the pressing member 531 presses the electronic component (ED) downward by the weight of the electronic component (ED), the electronic component (ED) (ED) has only a slight movement. Therefore, the weight of the pressing member 531 should be determined in consideration of the upward force received by the electronic component (ED) when the lock release device 520 operates.

Next, the adjustment element (SD) operates to narrow the gap between the gripping members (GE) to grip the electronic component (ED) as shown in FIG. 15. At this time, the adjustment elements (SD) may operate selectively to selectively grip only the front or rear electronic components (ED).

In the state of FIG. 15, the lifting source 533 operates to raise the pressing member 531, and the lifting source 513a raises the grip levers 511a and 511c. And when the lock release device 520 operates and the release members 521a and 521b rise, the horizontal mover 540 operates to move the electronic component (ED) in the horizontal direction and then to the electronic component picking device 510. Place the electronic component (ED) held by the device at the target location. Here, the process of putting down the electronic component (ED) can be accomplished by operating only the electronic component picking machine 510. Of course, if there is a locking structure where the electronic component (ED) must be placed, operation of the lock release device 520 will also be necessary.

In addition, when the angle of the electronic component (ED) needs to be adjusted, the rotator 550 operates to rotate the electronic component picking machine 510 to rotate the electronic component (ED). When the rotator 550 is operated, the electronic component (ED) can be rotated. The electronic component (ED) is moved at a certain angle.

As described above, the specific description of the present invention has been made by way of examples with reference to the accompanying drawings.
