Description

An align apparatus of object < RTI ID = 0.0 >

The present invention relates to an alignment object aligning apparatus, and more particularly, by adopting a structure in which only two edge portions are aligned by pushing and not aligning the four sides of the alignment target body, the structure of the aligning apparatus is simplified, It is possible to perform alignment on a plurality of alignment targets at once and thus to reduce the tact time of the entire process, The present invention relates to an alignment object aligning apparatus capable of enhancing alignment object alignment.

In a semiconductor, a display manufacturing process, a glass processing process, and a cell processing process, an alignment process for a target object is generally included. That is, when alignment is required in the process of moving the object to be processed to the next process, or alignment is necessary in order to move the object to the correct position, the alignment process is performed on the object to be processed.

The sorting method for the to-be-processed object can be variously configured. For example, Korean Patent Registration No. 10-1493913 (sheet cutting apparatus) discloses a technique of aligning sheets using alignment bars.

The alignment method in the sheet cutting apparatus aligns the alignment bars by vertically arranging the alignment bars on four sides of the stage and moving the alignment bars in a direction orthogonal to the side surface of the stage.

However, since the aligning method using the conventional aligning bar as described above has a structure in which four sides of the object to be processed, that is, the aligning object are pushed and aligned, the structure of the aligning device is more complicated than necessary, It is difficult to cope with this problem.

In particular, since the alignment method using the conventional alignment bar can perform the alignment process for one alignment target object and can not simultaneously perform alignment for a plurality of alignment target objects, There is a disadvantage that the tact time is increased more than necessary and the production efficiency is deteriorated as a result.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art described above, and it is an object of the present invention to provide a method of aligning and aligning four sides of an object to be aligned, Alignment of the alignment target can be performed at the same time by arranging the plurality of alignment means to horizontally move at the same time at a time, so that alignment for a plurality of alignment targets can be performed at a time, Which is capable of increasing the production efficiency of the alignment object alignment apparatus.

According to another aspect of the present invention, there is provided an alignment object aligning apparatus for aligning an object to be aligned, the aligning object aligning apparatus comprising: a base disposed on an upper surface of the base so as to be slidable in a direction parallel to a virtual oblique line; A pair of sliders arranged so as to be simultaneously slidable in directions opposite to each other, driving means for driving the pair of sliders so as to be simultaneously slidable in mutually opposite directions, A pair of sliders arranged on an arbitrary diagonal line parallel to the imaginary diagonal line and slidably aligning the diagonal edge portions of the alignment target on the stage as the pair of sliders are slid close to each other, And an alignment means for aligning the plurality of pixels.

Here, the pair of alignment means may be a plurality of alignment means, arranged in parallel with each other so as to be coupled to the pair of sliders, and a plurality of pair of alignment means may simultaneously align the alignment target bodies disposed therebetween .

Here, each of the pair of sliders is disposed so that both ends of the pair of sliders can be slidably engaged with a pair of rails disposed on the base, and the pair of rails are disposed to be parallel to the virtual oblique lines, respectively .

The driving means includes a pinion gear disposed above the base and coupled to the rotating shaft of the driving motor to rotate, and a pinion gear coupled to the pinion gear such that the pinion gear is opposed to and parallel to the pinion gear, And one end of each of the pair of sliders is fixedly coupled to one of the pair of sliders and the other end of the pair of sliders is fixed to the other of the pair of sliders And a rack bar fixedly coupled to the slider on the side of the rack bar.

Each of the pair of alignment means may include a support bar coupled to the slider, a pair of alignment pins coupled to the upper portion of the support bar to be in contact with adjacent portions on both sides of the alignment target body in the process of aligning the alignment target, And the like.

According to the alignment object aligning apparatus of the present invention having the above-described problems and the solution, since the structure for aligning and aligning only the two corner portions is adopted instead of the structure for aligning the four sides of the alignment target body by sliding, And alignment can be performed for alignment objects of various sizes.

In addition, since the plurality of alignment means can be horizontally moved simultaneously at the same time, it is possible to perform alignment on a plurality of alignment targets at one time, and as a result, it is possible to reduce the tact time of the entire process, .

The sizes and shapes of the components shown in the drawings may be exaggerated for clarity and convenience. In addition, terms defined in consideration of the configuration and operation of the present invention may be changed according to the intention or custom of the user, the operator. Definitions of these terms should be based on the content of this specification.

1 is a perspective view of an alignment object aligning apparatus according to an embodiment of the present invention, FIG. 2 is a plan view of an alignment object aligning apparatus according to an embodiment of the present invention, and FIG. 3 is a cross- Fig.

1 to 3, the object aligning apparatus 100 according to the embodiment of the present invention includes a pair of sliders 31 disposed slidably in a virtual oblique line (VD) direction on a base, A driving means 50 for driving the pair of sliders 31 so as to be reciprocated in a direction MD parallel to the imaginary oblique line VD and a pair of sliders 31, (As indicated by reference numeral 3 in FIG. 4) of the alignment target body (indicated by reference numeral 1 in FIGS. 4 to 7) as the slider moves, and a pair of alignment means (70).

What is important here is that the pair of sliders 31 are arranged and driven so as to be movable in a direction parallel to the imaginary oblique line VD (the moving direction MD of the pair of sliders) The aligning means 70 also horizontally moves in a direction parallel to the imaginary oblique line VD to bring the corner 3 of the alignment target object 1 into contact and push and align.

The alignment target according to the present invention is a concept including both a glass, a cell, or a pallet on which the glass or cell is placed.

The virtual oblique line VD is not an imaginary straight line VB parallel or orthogonal to the side surface of the base 10 as shown in Figs. 1 and 2, but rather an imaginary oblique line VD, It corresponds to the oblique line. In other words, the virtual oblique lines VD are arranged in a diagonal direction of the alignment target object (indicated by reference numeral 1 in FIG. 4) arranged and arranged between the pair of alignment means 70 (The diagonal direction formed in the direction of the arrow A).

As a result, the virtual slant VD corresponds to a line parallel to a line connecting both edges 3 formed in the diagonal direction of the aligned object 1 in an aligned state, and the pair of sliders 31, And the pair of aligning means 70 are horizontally reciprocated in the direction parallel to the line connecting the imaginary oblique lines VD, that is, both edges 3 formed in the diagonal direction of the aligned object 1 in the aligned state, And is moved and driven. That is, the horizontal reciprocating direction MD of the pair of sliders 31 and the pair of aligning means 70 is parallel to the imaginary oblique line.

The pair of sliders 31 horizontally reciprocating in a direction parallel to the virtual oblique line VD as described above is disposed on the upper surface of the base 10, as shown in Figs. The base 10 corresponds to a flat plate having a predetermined shape, preferably a rectangular shape, and serves as a plate or a support plate for arranging the pair of sliders 31, the pair of alignment means 70 .

As shown in FIGS. 1 to 3, the pair of sliders 31 disposed on the base 10 as described above are preferably formed of two pieces, spaced apart from each other by a predetermined distance, and arranged parallel to each other. However, the pair of sliders 31 are arranged so as to be movable in a direction parallel to a line connecting the imaginary oblique lines VD, that is, both edges 3 in the diagonal direction of the object 1 to be aligned. That is, the virtual oblique line VD and the moving direction MD of the pair of sliders 31 are in a mutually parallel relationship.

The pair of sliders 31 can be arranged in various directions as long as they can be reciprocated in a direction parallel to the virtual oblique line (VD) direction. In Figs. 1 to 3, the pair of sliders 31 are arranged in a direction parallel to the imaginary straight line VB. That is, the pair of sliders 31 can be arranged in a direction parallel to various lines such as the imaginary straight line VB or an arbitrary slant line, but they must be arranged so as to be moved in a direction parallel to the virtual slant line . That is, the horizontal reciprocating movement direction MD of the pair of sliders 31 must be parallel to the imaginary slant VD.

On the other hand, the pair of sliders 31 are disposed on the base so as to be horizontally reciprocated in a direction parallel to the virtual oblique line VD, but they are always moved at the same time, The direction is opposite. That is, the pair of sliders 31 are disposed on the base so that they can move at the same time, but can slide in mutually opposite directions.

In other words, the pair of sliders 31 constituting the aligned object aligning apparatus according to the embodiment of the present invention can be slid in a direction parallel to the virtual oblique line VD on the upper surface of the base 10 So that they can be simultaneously slid in mutually opposite directions. That is, the two sliders 31a and 31b constituting the pair are simultaneously moved in the opposite direction to move away from each other or close to each other.

The pair of sliders 31 need not be arranged so as to be able to slide in a direction parallel to the imaginary oblique line VD while maintaining a parallel state, And it is preferable that they are arranged so as to be simultaneously slidable in mutually opposite directions.

The pair of sliders 31 can be horizontally reciprocated in a direction parallel to the imaginary oblique line VD by the driving means 50 and are driven so as to be able to slide in opposite directions while moving at the same time.

That is, the driving unit 50 is driven so that the pair of sliders 31 can be horizontally reciprocated in the direction parallel to the imaginary oblique line VD, but can be simultaneously slid in opposite directions . Specifically, the driving means 50 drives the pair of sliders 31 so that they can slide at the same time in the opposite direction, so that they can move away from each other or approach each other.

As a result, the pair of sliders 31 are simultaneously moved away from the two corners 3 formed in the diagonal direction of the alignment target body 1 by driving of the driving means 50, Can be.

A pair of alignment means 70 coupled to each of the pair of sliders 31a and 31b is disposed at the same time from both edges 3 formed in the diagonal direction of the alignment target object 1 Or moved close to both edges 3 at the same time. As a result, the pair of alignment means 70 can simultaneously align the alignment target body 1 by simultaneously pushing both edges 3 formed in the diagonal direction of the alignment target body 1.

As described above, according to the alignment object aligning apparatus of the present invention, the pair of alignment means 70 are sequentially moved to align the alignment target body 1, .

Therefore, the alignment object alignment apparatus according to the present invention has an advantage that the alignment process is very simple and quick. In addition, instead of sequentially aligning the four sides of the object to be aligned, the two corner portions of one of the two diagonal directions of the object to be aligned, which are arranged in one diagonal direction, are simultaneously pushed and aligned, Is relatively simple, and the alignment time is greatly shortened.

As described above, the driving unit 50 is driven such that the pair of sliders 31 can be slid in a direction parallel to the virtual slant VD, so that they can simultaneously move at the same time and slide in the opposite direction . Accordingly, if the driving means 50 can simultaneously move the pair of sliders 31 in opposite directions, it is possible to adopt various components, be connected in various ways, have. However, a preferable structure, a connection structure, a driving and an arrangement structure of the driving means will be described later.

As described above, the alignment target body 1 is aligned by receiving external forces simultaneously at two corners 3 disposed in one diagonal direction out of two diagonal directions. The pair of alignment means 70 corresponds to the pair of sliders 31 so as to apply a fine external force in the horizontal oblique direction while being in contact with both edges 3 of the alignment target object 1 .

That is, one of the pair of alignment means 70 is coupled to one slider 31a of the pair of sliders 31, and the other alignment means is coupled to the other slider 31a, (31b). Specifically, among the pair of alignment means 70, the support bar 71a of one aligning means is coupled to one slider 31a of the pair of sliders 31, And the support bar 71b of the aligning means is engaged with the other slider 31b.

The pair of alignment means 70 is coupled to the pair of sliders 31 so that as the pair of sliders 31 moves in a direction parallel to the virtual slant VD, And moves in a direction parallel to the virtual oblique line.

As a result, the pair of aligning means 70 are moved in the same direction along the moving direction MD of the pair of sliders 31, and are aligned in the diagonal direction of the aligned object 1 3).

The pair of alignment means 70 moves along the line segment PL which is subsequently extended to both edges 3 of the alignment target object 1 in the aligned state, as shown in Fig. That is, the movement path of the pair of alignment means 70 is on a line segment PL which is extended from both edges 3 of the alignment target object 1 in an aligned state.

As shown in FIGS. 1 to 3, the pair of alignment means 70, which move in the direction parallel to the imaginary oblique line VD as described above, (Arranged in a line segment (PL) that extends laterally from both edges of the alignment target in an aligned state) parallel to the imaginary oblique line (VD), and the pair of sliders Aligns and aligns the diagonal edge 3 portions of the alignment target object 1, which are seated on the stage, as they are slid toward each other.

Each of the pair of alignment means is vertically coupled to each of the pair of sliders 31 (31a, 31b). Therefore, the pair of sliders 31 move together with the movement, and move in the same direction as the movement directions MD of the pair of sliders.

The pair of aligning means 70 is formed by arranging any two oblique lines parallel to the above-mentioned virtual oblique line VD, that is, a line segment PL extending in succession from both edges 3 of the alignment target object 1 in an aligned state . In other words, a line segment (denoted by PL in Figs. 2 and 4) extending from each center of the pair of alignment means 70 is disposed at both corners of the alignment target object 1 in an aligned state 3) and the extended line segment PL. As a result, since the alignment target objects to be aligned on the stage are in a slightly misaligned state, the pair of alignment means can apply an external force (pushing force) to both edges in the diagonal direction of the alignment target object.

Since the pair of sliders 31 move in opposite directions, the pair of alignment means 70 also move in opposite directions. Therefore, the pair of alignment means 31 also move so as to be close to each other or away from each other.

The alignment target body 1 is disposed between the pair of alignment means 70. That is, the object to be aligned 1 is disposed between the pair of alignment means 70, and simultaneously receives an external force on both diagonal edge portions 3 thereof by the pair of alignment means 70 .

The alignment target object 1 is seated on the stage by a transfer device such as a pick and place, and the alignment target object in the seated state is somewhat misaligned, that is, misaligned (see Fig. 4 (a) The alignment target object 1 in the state can be aligned by applying an external force to both corner portions of the diagonal direction of the pair of alignment means 70 simultaneously (see FIG. 4 (b)).

As described above, the alignment target body 1 is disposed between the pair of alignment means 70, and can be placed on a stage of a predetermined shape. This will be described later.

As a result, the pair of alignment means 70 move together as the pair of sliders 31 move in mutually opposite directions, so that diagonal edges 3 (see FIG. 3) of the alignment target object 1, ) Portion can be pushed and aligned. That is, the pair of alignment means 70 pushes the diagonal edge 3 portions of the alignment target object 1, which is seated on the stage, as the pair of sliders 31 are slid so as to approach each other .

As described above, the alignment object aligning apparatus according to the embodiment of the present invention does not align the four sides of the alignment target body in order by sequentially pushing them, but a pair of sliders 31 and a pair of alignment means 70 (3) positioned in one diagonal direction (direction in which the pair of alignment means are disposed) out of two diagonal directions of the alignment target object (1) are simultaneously pushed and aligned. Therefore, the structure of the object aligning apparatus becomes simple, the alignment process with respect to the aligning object becomes simple, and the time required for the aligning can be greatly reduced.

Specifically, a conventional aligning method for an alignment object has four alignment bars that can horizontally move toward four sides of the aligning object, and a pair of alignment bars facing each other among the four alignment bars are moved, The alignment object is aligned in one direction, and the other alignment bar is moved in the opposite direction to align the alignment object.

Alternatively, the alignment object aligning apparatus according to an embodiment of the present invention may be configured such that alignment means simultaneously move toward a pair of edges positioned in a diagonal direction of the alignment target object, . Accordingly, the alignment object aligning apparatus according to the embodiment of the present invention has an advantage that the alignment speed is faster than that of the conventional alignment method, the structure for alignment is simple, and the alignment process is simplified.

As described above, the alignment object aligning apparatus according to the embodiment of the present invention aligns both edges 3 of the alignment target body 1 disposed between the pair of alignment means 70 in the opposite direction .

The pair of alignment means 70 are vertically coupled to the pair of sliders 31 and the pair of sliders 31 are moved in a direction parallel to a virtual oblique line, 1 by aligning the alignment target body 1 by simultaneously pushing the portions of both edges 3 located in the diagonal direction. Accordingly, by aligning another pair of alignment means 70 with the pair of sliders 31, it is possible to simultaneously perform the alignment process for a plurality of the alignment targets 1 at the same time.

Therefore, in the aligned object aligning apparatus according to the embodiment of the present invention, the pair of aligning means 70 is constituted by a plurality of arrangements, as shown in FIGS. 1 to 4, And the pair of alignment means 70 are arranged to be coupled to the pair of sliders 31. The pair of alignment means 70 simultaneously aligns the alignment target bodies 1 disposed therebetween.

Specifically, the pair of alignment means 70 according to the present invention may be arranged in a plurality of the sliders 31 as shown in FIG. 1 to FIG. In Fig. 1 to Fig. 4, the pair of alignment means 70 is arranged in four, i.e., four pairs.

Each pair of alignment means 70 is arranged in a direction parallel to the imaginary oblique line VD, as shown in Figs. That is, as shown in FIGS. 2 and 4, a line PL formed successively from the center of each pair of alignment means 70 is parallel to the virtual oblique line VD.

All other pairs of alignment means 70 are also arranged in a direction parallel to the imaginary oblique lines. As a result, the lines formed by the respective pair of alignment means 70 (lines PL formed subsequently to the centers of the pair of alignment means) are all parallel to each other and parallel to the virtual oblique lines.

Further, between the pair of alignment means 70, the alignment target body 1 is placed on the stage. Thus, each of the pair of alignment means 70 pushes and aligns the two corners 3 located in the diagonal direction of the alignment target 1 disposed therebetween.

Particularly, since the plurality of pair of aligning means 70 are coupled to the pair of sliders 31, one of the pair of aligning means 70 (one pair of sliders 1 and 2) and the other alignment means (a pair of sliders 31), which are joined to one of the sliders 31a and 31a, The aligning means (aligning means arranged one below the other in Fig. 1 and Fig. 2) to be engaged with the other slider 31b of the pair of sliders 31 move in the opposite direction , An external force can be applied to the edge (3) of the alignment target object (1).

As a result, the aligning process for a plurality of the alignment targets 1 can be performed at a time by a plurality of alignment means 70 coupled to the pair of sliders 31. The pair of alignment means 70 are spaced apart from each other in the adjoining pair of alignment means 70 and remain in a parallel state and each pair of alignment means 70 is arranged between themselves Perform alignment on the alignment object.

As described above, at least one pair of alignment means 70 is coupled to the pair of sliders 31 so that the respective alignment means constituting the pair of alignment means 70 are moved away from each other or close to each other Moving to be able to be.

The pair of sliders 31 constitute a slider assembly 30. That is, the slider assembly 30 includes at least one pair of sliders 31 and a rail 33 that serves as a guider to slide the at least one pair of sliders 31 .

Therefore, as shown in FIGS. 1 to 3, each of the pair of sliders 31 constituting the slider assembly 30 includes a pair of sliders 31a and 31b, both ends of which are disposed on the base 10 Are arranged so as to be able to slide and engage with the pair of rails 33, respectively. The pair of rails 33 are also arranged in a direction parallel to the imaginary oblique line VD so that the pair of sliders 31 can be moved in a direction parallel to the imaginary oblique line VD .

In summary, each of the pair of sliders 31 (31a, 31b) is arranged so that both ends thereof can be engaged with and slidable on a pair of rails (33) disposed on the base (10) Each of the rails 33 is arranged to be parallel to the virtual oblique line VD.

The pair of rails 33 are arranged in a direction parallel to the virtual oblique line VD and both ends of the pair of sliders 31 are slidably engaged with the pair of rails 33, The moving direction MD of the pair of sliders 31 sliding along the pair of rails becomes parallel to the imaginary slant VD.

The reason why the pair of sliders 31 can be moved along the pair of rails 33 is that the driving means 50 is coupled to the pair of sliders 31 and driven. That is, the driving means 50 is connected to the pair of sliders 31 so that the pair of sliders 31 are simultaneously slid in mutually opposite directions, and the pair of sliders 31 are slid in the direction parallel to the imaginary slant VD And is reciprocally movable.

1 to 3, the driving means includes a pinion gear 53 disposed on the base 10 and coupled to the rotating shaft 51a of the driving motor 51 to rotate, (55a, 55b) so as to mutually oppose and parallel to each other and to perform linear motion in mutually opposite directions in accordance with the rotation of the pinion gear (53), each of the pair of gears One end of one of the pair of sliders 31 is fixedly coupled to one of the pair of sliders 31 and the other end of the pair of sliders 31 is fixed to the other of the pair of sliders 31 And a rack bar 55 fixed to the slider 33b.

The pinion gear (53) is rotatably mounted on the base (10). The rotation of the pinion gear 53 is achieved by driving a drive motor 51 disposed below the base 10. That is, the pinion gear 53 is coupled to the rotating shaft 51a of the driving motor 51, and the pinion gear 53 coupled to the rotating shaft 51a is driven by the driving motor 51, Can be rotationally driven.

The pair of rack bars 55 are engaged with the pinion gear 53. The pair of rack bars 55 are engaged with the pinion gear 53 to convert the rotational motion of the pinion gear 53 into a linear motion.

The pair of rack bars 55 are engaged with the pinion gears 53 so as to be held in parallel with each other. As a result, when the pinion gear 53 is rotated in one direction, the pair of rack bars 55 are moved in mutually opposite directions.

On the other hand, of the rack bars 55 constituting the pair of rack bars 55, only one of both ends of the one rack bar 55a has one of the pair of sliders 31 And only one of both ends of the rack bar 55b of the other rack bar 55b is fixedly coupled to only the other slider 31b of the pair of sliders 31. [

As a result, when the pair of rack bars 55 move in mutually opposite directions, the pair of sliders 31 are also moved in mutually opposite directions.

The pair of rack bars 55 are arranged in parallel to the virtual oblique line VD so that the pair of sliders can be moved along the rail 33 in a direction parallel to the virtual oblique line VD. Direction. As described above, one rack bar 55a is fixedly coupled to only one slider 31a, and the other rack bar 55b is fixedly coupled only to the other slider 31b.

Accordingly, the pair of rack bars 55 are moved in opposite directions in accordance with the rotation of the pinion gear 53, and the pair of sliders 31 are moved in a direction parallel to the virtual oblique line . 2, when the pinion gear 53 rotates in the clockwise direction, the pair of sliders 31 are driven to approach each other, and when the pinion gear 53 rotates counterclockwise, the pair of sliders 31 So that they can be moved away from each other.

As described above, one end of the one rack bar 55a is fixedly coupled to only one of the sliders 31a, and the other end of the rack bar 55b is fixed only to the other slider 31b The pair of rack bars 55 can be moved in opposite directions when the pinion gear 33 rotates.

As described above, only one end of each of the pair of rack bars 55a and 55b is fixedly coupled to the corresponding sliders 31a and 31b, and the other end is not coupled to the slider.

Since only one end of each of the pair of rack bars 55 is coupled to the slider and the other end of the pair of rack bars 55 is not coupled to the slider as described above, It may shake or the stability may be deteriorated.

Therefore, the pair of rack bars 55 can be guided while being supported by the guide rollers 57a and 57b. That is, the guide rollers 57a and 57b are disposed on the base 10 so as to be spaced apart from each other. The guide rollers 57a and 57b guide movement of any one of the pair of rack bars 55.

More specifically, one of the pair of guide rollers 57a and 57b is disposed on the base 10 adjacent to the one slider 31a, and the other 57b is disposed on the other side And is disposed on the base 10 adjacent to the slider 31b on the left side. One of the pair of guide rollers 57a and 57b guides the movement of the rack bar 55a coupled to the other slider 31b while the other 57b Feeds the movement of the rack bar 55b, which is coupled to the one slider 31a.

The pair of guide rollers (57a, 57b) are arranged so as not to interfere with the movement of the pair of sliders (31). That is, the pair of guide rollers 57a and 57b may be formed to have a height lower than a height corresponding to the distance between the pair of sliders 31 in the base 10. Therefore, the pair of sliders can be moved without being caught by the pair of guide rollers in the moving process.

The pair of alignment means (70) is coupled to the pair of sliders (31) slid by the driving means (50). As a result, as the driving means 50 moves the pair of sliders 31, the pair of alignment means 70 move.

As shown in FIGS. 1 to 3, the pair of aligning means 70 is arranged to be coupled to the pair of sliders 31 in the vertical direction, And aligns and aligns the diagonal edge portions 3 of the alignment target object 1, which are seated on the stage, as the pair of sliders 31 are slid close to each other.

Specifically, the pair of alignment means 70 are coupled to the pair of sliders 31 one by one, and vertically arranged. That is, among the pair of alignment means 70, one of the alignment means 71a and 73a is vertically coupled to one of the sliders 31a and the other alignment means 71b, 73b) is vertically coupled to the other slider 31b.

As described above, among the pair of alignment means 70, a plurality of alignment means (alignment means constituted by one alignment means 71a, 73a) is provided and is arranged in a direction perpendicular to the one slider 31a And the other of the alignment means 71b and 73b may also be configured to be coupled to the other slider 31b in the vertical direction. That is, as shown in FIGS. 1 to 3, the pair of alignment means 70 may be arranged in a state of being separated from each other by the pair of sliders 31.

The pair of alignment means 70 is not arranged on four sides of the alignment target body like the conventional aligning apparatus but is arranged in the vicinity of both diagonal corners of the alignment target body 1. [

Specifically, the pair of alignment means 70 is arranged on any diagonal line parallel to the imaginary oblique line VD. As described above, the arbitrary slant line corresponds to a line segment PL extending in a diagonal direction with both corners continuing in a state in which the alignment target body is aligned.

The pair of aligning means 70 moves along the line segments PL extending in the diagonal direction with both corners continuing in a state where the alignment target body is aligned. As a result, the pair of alignment means 70 can align the alignment target object by pushing both edges 3 of the alignment target object 1.

As the pair of sliders 31 move in a direction parallel to the imaginary oblique line, the pair of aligning means 70 also moves in a direction parallel to the imaginary oblique line. As described above, the pair of alignment means 70 are moved in opposite directions to each other or moved away from each other.

The pair of alignment means 70 is moved so that the pair of the sliders 31 are brought closer to each other as they are brought closer to each other and as a result, The alignment target body can be aligned by one operation by pushing each of the edge portions 3 of the direction.

1 to 3, the pair of alignment means 70 operated as described above includes support bars 71a and 71b vertically coupled to the pair of sliders 31, And a pair of alignment pins 73a and 73b which contact and press the edge 3 of the alignment target object 1.

That is, each of the pair of alignment means 70 includes supporting bars 71a and 71b coupled to corresponding sliders 31, and a pair of supporting bars 71a and 71b, And a pair of alignment pins 73a and 73b that are in contact with adjacent portions on both sides of the edge 3 of the alignment target body 1 in the process of aligning the alignment target body 1.

The support bars 71a and 71b constituting the respective alignment means 70 are vertically coupled to the slider 31 to which they are coupled. A pair of alignment pins 73a and 73b are coupled to the support bars 71a and 71b. The pair of alignment pins 73a and 73b press both side portions (both sides) adjacent to the edge 3 of the alignment target object 1 in the process of aligning the alignment target object 1, To be aligned.

As shown in FIG. 1, FIG. 2 and FIG. 4, the pair of alignment pins 73a and 73b constituting each alignment means 70 are arranged in the diagonal direction So that the alignment target object can be aligned by pushing the edge of the misaligned alignment target object.

The alignment process of the alignment target object 1 by the aligned object alignment apparatus 100 will be described below. 4 is a schematic view for explaining an aligning object aligning process using the aligning object aligning device according to an embodiment of the present invention.

Specifically, FIG. 4A shows a state in which the object to be aligned 1 is not aligned in a state where it is seated on the stage, that is, a state in which the object is misaligned. FIG. The alignment target object 1 placed on the alignment target 1 is in an aligned state.

As shown in Fig. 4 (a), when the object to be aligned 1 is placed on the stage, it remains in a misaligned state. Each of the alignment targets 1a, 1b, 1c and 1d is arranged between a pair of alignment pins constituting each pair of alignment means. That is, among the four alignment targets 1, the first alignment target 1a is disposed between the first pair of alignment pins 73a1 and the second pair of alignment pins 73b1 constituting a pair of alignment means The second alignment object 1b is disposed between the first pair of alignment pins 73a2 and the second pair of alignment pins 73b2 constituting a pair of alignment means and the third alignment object 1c The fourth alignment object 1d is arranged between the first pair of alignment pins 73a3 and the second pair of alignment pins 73b3 constituting a pair of alignment means and the last alignment object 1d is constituted by a pair of alignment means And is disposed between the first pair of alignment pins 73a4 and the second pair of alignment pins 73b4.

Here, the first pair of alignment pins and the second pair of alignment pins are formed by sequentially extending both edges in the diagonal direction of the alignment target object in the aligned state as shown in FIG. 4 (b) And moves along the line segment PL so as to align the alignment target body 1.

Wherein a line segment (PL), which is a line extending in both diagonal directions of the alignment target in the aligned state, is parallel to the imaginary slant line (VD), and the first pair of alignment lines Corresponds to the path through which the alignment pin and the second pair of alignment pins move (indicated by the red arrow in FIG. 4).

As described above, the first pair of alignment pins (for example, 73a1) and the second pair of alignment pins (for example, 73b1) that constitute the pair of alignment means are the alignment object 1 (Both side surfaces) of the edge 3 positioned in the diagonal direction of the frame 3. That is, the two alignment pins 73a1 'and 73a1' constituting the first pair of alignment pins (for example, 73a1) included in the pair of alignment means and the second pair of alignment pins The two alignment pins 73b1 'and 73b1 "constituting the alignment body 73b1 are moved so as to press both adjacent portions of the edge 3 of the alignment target body 1, respectively.

As shown in FIG. 4, the two alignment pins constituting each of the pair of alignment pins are formed of a line segment PL extending continuously along both edges positioned in the diagonal direction of the alignment target object while being spaced apart from each other, The two alignment pins constituting the pair of alignment pins can press adjacent side portions of the edge 3 of the misaligned alignment object 1. [

That is, in the process of pressing the edge portion of the alignment target object 1, the edge 3 of the alignment target object is disposed between the two alignment pins. As a result, the alignment target body can be finely moved and aligned, as shown in Fig. 4 (b).

When the alignment target object 1 is placed on the stage by a conveying device such as a pick and place, it is generally in a misaligned state but in a slightly misaligned state in the aligned state. Therefore, in the process of pressing the edge portion of the alignment target object 1, the edge 3 of the alignment target object can be disposed between the two alignment pins And as a result, the alignment target can be aligned while finely moving by pressing on the pair of alignment pins.

The movement of the first pair of alignment pins and the second pair of alignment pins included in the pair of alignment means moves to an alignment position where the alignment target can be finely moved and aligned. It is a matter of course that the alignment positions of the alignment pins are set in advance, and it is a matter of course that the alignment pins are driven so that the alignment pins can be moved to the alignment position.

The alignment position of the alignment pins is changed according to the size of the alignment target. That is, as the size of the alignment target placed on the stage is changed, the moving distance, position, and the like of the pair of alignment pins moving to align the alignment target object are newly set.

The alignment object aligning apparatus 100 according to the embodiment of the present invention described above can carry out the alignment process with respect to the alignment target object placed on the stage. However, the size of the alignment target placed on the stage can be changed. That is, the alignment target objects placed on the stage may have various sizes.

In this case, it is necessary to adjust the distance between the alignment targets. For example, if the size of the object to be aligned is large, it is necessary to arrange the object so that the distance between the objects is further apart. If the size of the object is relatively small, It is irrelevant.

In order to adjust the distance between the alignment targets as described above, it is necessary to adjust the interval between the stages for seating the alignment target. Therefore, the aligned object aligning apparatus 100 according to the embodiment of the present invention may further include the stage supporting / controlling means 90. [

Fig. 5 shows the arrangement of the alignment object aligning apparatus including the stage support / control means 90 applied to the present invention, and Fig. 6 is a perspective view showing only the stage support / control means 90. Fig.

5 and 6, the stage support / control means 90 includes a support plate 91, a pair of movement modules 93, a stage assembly 95 and a sliding guider 97, do.

The support plate 91 is a component for arranging and supporting the components constituting the stage support / control means 90. The support plate 91 is disposed between the pair of alignment means so as not to interfere with the movement of the pair of alignment means 70.

On the support plate 91, a pair of moving modules 93 are arranged. Each of the pair of moving modules 93 includes a moving motor 93a, a ball screw 93b, a rotating support 93c and at least one moving body 93d and 93e.

The moving motor 93a transmits a rotational force to the ball screw 93b. The rotary support 93c supports the end of the ball screw 93b so that the ball screw can be stably rotated.

The at least one moving body 93d and 93e are engaged with the ball screw 93b. Accordingly, the at least one moving body 93d, 93e moves in the direction in which the ball screw is disposed in accordance with the rotation of the ball screw.

It is preferable that the at least one moving body 93d and the moving body 93e are constituted by a plurality of moving bodies 93d and 93e. The moving bodies 93d and 93e move in conjunction with the ball screw, And is disposed in engagement with the ball screw so as to be movable. That is, the moving bodies move toward or away from each other as the ball screw rotates.

Each of the moving bodies is engaged with the stage assembly 95. As a result, the moving bodies move with the rotation of the ball screw, and as a result, the stage assemblies 95, which are respectively engaged with the moving bodies, are moved. Accordingly, the alignment targets placed on the respective stages 95a constituting the stage assemblies 95 may be close to each other or may be spaced apart from each other.

The stage assembly 95 includes a stage 95a on which the alignment target 1 is mounted and is coupled to the moving body, a support connecting bar 95b for supporting the stage 95a, And a sliding coupling 95c connected to the sliding guider 97 and movably engaged with the sliding guider 97. Preferably, the sliding guider has a rail shape.

The sliding engagement portion 95c is engaged with the sliding guider 97 disposed along the center portion of the support plate 91 so as to be slidable when an external force is generated.

That is, when the ball screw is rotated according to the driving of the moving motor 93a, the moving bodies 93d and 93e coupled thereto move along the arrangement direction of the ball screws, and the stage assembly 95, which is coupled to the moving body, So that the slide assembly can be moved along the sliding guider.

As a result, the distance between the plurality of stage assemblies can be adjusted by the stage support / control means 90 having the above-described configuration, and as a result, the distance between the alignment targets placed on the respective stage assemblies can be adjusted have. Therefore, even if the size of the object to be aligned is changed, it is possible to perform the alignment process for the objects to be aligned having various sizes using the alignment object aligning apparatus according to the present invention after adjusting the arrangement distances between the alignment objects. have.

FIG. 7 is a schematic view showing an alignment process for an alignment target object using the alignment object aligning apparatus including the stage support / control means 90 described above.

As shown in Fig. 7 (a), in order to align the alignment objects placed on the stage assembly, the pair of sliders 31 are driven so as to be close to each other. As a result, the alignment pins 73a and 73b constituting the pair of alignment means move toward the edge portions of the alignment target object, respectively.

7 (b), the alignment pins 73a and 73b constituting the pair of alignment means press the edge portion 3 in the diagonal direction to align the alignment target body .

At this time, the pair of sliders 31 move in a direction parallel to the virtual oblique line VD as described above. That is, the moving direction of the pair of sliders (indicated by a red arrow) corresponds to a direction parallel to the virtual slant VD.

The alignment pins 73a and 73b constituting the pair of alignment means are arranged along the line segment PL connecting the two edges 3 in the diagonal direction of the alignment target in the aligned state Move. Accordingly, the alignment pins 73a and 73b constituting the pair of alignment means can move toward the diagonal edge 3 of the alignment target object 1, respectively, and consequently push the edge, To be aligned.

As described above, since the alignment object aligning apparatus 100 according to the embodiment of the present invention adopts a structure for pushing and aligning only two corner portions rather than a structure for pushing and aligning the four sides of the alignment target body, The structure is simplified, and alignment with respect to the alignment object of various sizes can be performed.

In addition, since the plurality of alignment means can be horizontally moved simultaneously at the same time, it is possible to perform alignment on a plurality of alignment targets at one time, and as a result, it is possible to reduce the tact time of the entire process, .
