  Referring to FIGS. 1 to 5, the alignment apparatus according to the present invention is an apparatus for performing an alignment operation or a position alignment operation on a workpiece (W) with a cutting apparatus or the like. The clamping units 110 and 120, the third and fourth clamping units 130 and 140, and the align driving unit 160 may be included.

  For reference, an alignment apparatus shown in the attached drawings includes a processing object (W) having a glass material (particularly, a tempered glass material), such as a window glass (Window Glass) of a small digital product such as a mobile phone or a navigation system. ) Is attached to a cutting device for cutting the frame. However, the present invention is not limited to glass workpieces, but can be applied to workpieces having various materials, and can also be applied to other types of cutting other than cutting. Of course you can. Also. In this specification, “cutting” may mean not only narrow-cutting in which a chip is generated but also broad-cutting including grinding.

  The jig 150 supports the workpiece (W) seated as shown in FIG. 1 to FIG. 3, and the workpiece (W) is cut during grinding or grinding on the workpiece (W). The position can be fixed. That is, the workpiece (W) can be seated on the jig 150 and fixed on the jig 150 during cutting or grinding. At this time, the jig 150 can fix the position of the workpiece (W) by a vacuum suction method. For this reason, at least one vacuum suction hole 151 for fixing the position of the workpiece (W) is formed on the jig 150 by vacuum suction of the workpiece (W) seated thereon. be able to. A vacuum suction line 152 extending from the vacuum suction hole 151 and having a predetermined geometric pattern as shown in FIG. 1 is provided on the upper surface of the jig 150 for efficient and stable vacuum suction.

  Referring to FIGS. 1 to 8, the first and second clamping units 110 and 120 are disposed to face each other in the length direction of the processing object (W) with the processing object (W) interposed therebetween. Thus, the third and fourth clamping units 130 and 140 are arranged so as to face each other in the width direction of the workpiece (W) with the workpiece (W) interposed therebetween. At this time, each of the four clamping units 110, 120, 130, and 140 can be driven to approach and separate from the workpiece (W) in a hinge manner.

Therefore, it is possible to control the drive more easily and more efficiently than the conventional alignment device, which must individually control a plurality of drive units, resulting in the accuracy of the drive mechanism. And reliability can be improved. In addition, the alignment apparatus according to the present invention simplifies the overall apparatus structure by minimizing the number of drive units required to perform the position alignment operation or alignment operation with respect to the workpiece (W). be able to.

  Hereinafter, a specific configuration of the four clamping units 110, 120, 130, and 140 and the align driving unit 160 and a driving mechanism thereof will be described in detail.

  First, the align driving unit 160 is a means for integrally driving the above-described clamping units 110, 120, 130, and 140. The actuator 161 generates a predetermined driving force, and the driving force of the actuator 161 is a clamping unit.

  The third clamping unit 130 and the fourth clamping unit 140 are preferably provided in a mutually symmetrical structure as shown in the attached drawings. This is because the first and second clamping units described above are provided. Similarly to 110 and 120, the third driving unit 160 and the fourth clamping unit 140 have substantially the same trajectory during the clamping operation and the unclamping operation, so that the align driving unit 160 performs the third and the third trajectories. The mechanism by which the fourth clamping units 130 and 140 are driven integrally can be simplified.

  Meanwhile, the second elastic member 182 may be provided between the third clamping unit 130 and the fourth clamping unit 140 as illustrated in FIGS. 4 and 7. The second elastic member 182 is a means for providing an elastic force in the direction in which the third clamping unit 130 and the fourth clamping unit 140 are separated from the workpiece (W). The third clamping unit 130 and the fourth clamping unit 140 may maintain an unclamping position as shown in FIGS. 1 to 5 before the align driving unit 160 is operated. At this time, the second elastic member 182 operates in the direction in which the upper ends of the third clamping unit 130 and the fourth clamping unit 140 are moved away from each other and the lower ends thereof are close to each other. Arranged on the hinge shafts 131 and 141 of the four clamping units 130 and 140. On the other hand, in this embodiment, the second elastic member 182 is provided with a compression coil spring as shown in FIGS. 4 and 7, and both end portions thereof are formed in the third and fourth clamping portions 130 and 140. Although it has a structure accommodated in each of the mounting grooves 130a and 140a, the present invention is not limited to this, and the type and mounting structure of the second elastic member 182 can be appropriately changed.

  In conclusion, the third and fourth clamping units 130 and 140 have substantially the same driving mechanism as the first and second clamping units 110 and 120 described above, and the configuration thereof is partially configured. Except for the above, it is substantially the same. The detailed configuration of the clamping units 110, 120, 130, and 140 will be described with only one, except for some configurations that are different.

  Each of the first to fourth clamping parts 110, 120, 130, 140 includes hinge arms 112, 122, 132, 142, clamping plates 114, 124, 134, 144, as shown in the attached drawings. And driven rollers 116, 126, 136, 146.

  The hinge arms 112, 122, 132, 142 are provided so as to be rotatable with respect to the hinge shafts 111, 121, 131, 141. At this time, the hinge shafts 111, 121, 131, 141 are fixed to the lower part of the jig base 155. The hinge arms 112, 122, 132, 142 are rotatably coupled to the hinge bracket 157.

  The clamping plates 114, 124, 134, 144 are provided on the upper ends 112 a, 122 a, 132 a, 142 a of the hinge arms 112, 122, 132, 142, and are processed by the hinge drive of the hinge arms 112, 122, 132, 142. It can approach and separate from one side of the object (W). At this time, the upper ends 112a, 122a, 132a, 142a of the hinge arms 112, 122, 132, 142 may be provided in a flat plate shape so as to stably support the clamping plates 114, 124, 134, 144. it can. The driven rollers 116, 126, 136, and 146 may be provided at the lower ends of the hinge arms 112, 122, 132, and 142 located below the hinge shafts 111, 121, 131, and 141. The driven rollers 116, 126, 136, and 146 are configured to rotate when the drive cam 163 comes into contact with the drive cam 163 of the align drive unit 160 and moves up / down, thereby driving the drive cam of the align drive unit 160. The driving of the clamping units 110, 120, 130, and 140 by 163 can be performed smoothly without difficulty.

  On the other hand, in the present embodiment, the hinge arm 112 of the first and second clamping portions 110 and 120 is taken into consideration that the workpiece (W) has a rectangular plate surface shape and is further extended in the length direction. 121 and the clamping plates 114 and 124 are provided in a size that is generally longer than the hinge arms 132 and 141 and the clamping plates 134 and 144 of the third and fourth clamping units 130 and 140. However, the shape and size of the first to fourth clamping units 110, 120, 130, and 140 can be appropriately changed depending on the shape and size of the workpiece (W).

  Referring to FIGS. 1 to 8, each of the first to fourth clamping units 110, 120, 130, and 140 is one end of the clamping plates 114, 124, 134, and 144 (close to the workpiece (W)). It may further include guide rollers 118, 128, 138, 148 that are provided at the end portion and come into contact with one side surface of the workpiece (W) at the clamping position. At this time, the guide rollers 118, 128, 138, and 148 move the workpiece (W) when the workpiece (W) moves in the length direction or the width direction in contact with one side surface of the workpiece (W). ) To rotate due to the frictional force.

  The alignment apparatus according to the present invention is aligned in four directions by a pair of clamping units 110 and 120 in the length direction of the workpiece (W) and a pair of clamping units 130 and 140 in the width direction of the workpiece (W). In general, the four clamping units 110, 120, 130, and 140 are not placed at the clamping position at the same time, but the first in the length direction depends on the initial position of the workpiece (W). The second clamping units 110 and 120 reach the clamping position first, or the third and fourth clamping units 130 and 140 reach the clamping position first in the width direction.

  If the first and second clamping units 110 and 120 reach the clamping position first, the third and fourth clamping units 130 and 140 thereafter move the workpiece (W) in the width direction. It is possible to reach the clamping position only by moving it. At this time, the guide rollers 118 and 128 provided in the first and second clamping units 110 and 120 are connected to the first and second clamping units 110, respectively. , 120 plays a role of smoothly moving the workpiece (W) in the width direction even at the clamping position for pressurizing the workpiece (W). On the other hand, when the third and fourth clamping units 130 and 140 reach the clamping position first, the first and second clamping units 110 and 120 thereafter lengthen the workpiece (W). It is possible to reach the clamping position only by moving in the direction. At this time, the guide rollers 138 and 148 provided in the third and fourth clamping units 130 and 140 are connected to the third and fourth clamps. Even when the ping units 130 and 140 are in a clamping position where the workpiece (W) is pressed, the workpiece (W) functions to smoothly move in the length direction. On the other hand, in this embodiment, two guide rollers 118, 128, 138, and 148 are provided for each clamping unit. However, the present invention is not limited to this, and the number of guide rollers is appropriately changed. Can be done.

Specifically, the shock absorbers 119 and 129 have upper ends 112a and 122a of the hinge arms 112 and 122 so as to act on the other ends of the clamping plates 114 and 124 (ends far from the workpiece (W)). Can be installed on one side. At this time, the shock absorbers 119 and 129 are expanded and contracted according to the force input from the outside, and as a means for performing a buffer function, an oil using a spring-type shock absorber on which a coil spring is mounted and a liquid viscous resistance. Any one of the shock absorbers can be used.

  As described above, the four clamping units 110, 120, 130, and 140 are not simultaneously placed at the clamping position, but the first and second clampings are performed according to the initial position of the workpiece (W). The units 110 and 120 can reach the clamping position first. However, since the four clamping units 110, 120, 130, and 140 are integrally driven by the align driving unit 160 in the present invention, it is assumed that the first and second clamping units 110 and 120 are clamped first. If the movement reaches the clamping position and further movement is constrained, the third and fourth clamping units 130 and 140 may stop moving without reaching the clamping position. May occur.

  The structure of the shock absorbers 119 and 129 in the present invention is for solving the above-described problems. The clamping plates 114 and 124 are connected to the hinge arm 112 and the first and second clamping parts 110 and 120, respectively. 122 is configured to be slidable within a predetermined section, but the shock absorbers 119 and 129 are configured to act on the other ends of the clamping plates 114 and 124, so that the first and Even if the second clamping units 110 and 120 first reach the clamping position, the align driving unit 160 causes the third and fourth clamping units 130 and 140 to continue to slide smoothly and reach the clamping position. You will be able to hesitate. Even if the first and second clamping units 110 and 120 reach the clamping position, the clamping plates 114 and 124 are fixed in position, but the third and fourth clamping units 130 and 140 are fixed. This is because the hinge driving of the hinge arms 112 and 122 of the first and second clamping units 110 and 120 continues smoothly without being restrained until reaching the clamping position.

  On the other hand, in the present embodiment, the first and second clampings that perform the alignment operation in the length direction in consideration of the fact that the workpiece (W) is larger in the length direction than the width direction. The shock absorbers 119 and 129 are provided in the portions 110 and 120. However, the present invention is not limited thereto, and the third and fourth clamping portions 130 and 130 may be used instead of the first and second clamping portions 110 and 120. Of course, each of the four clamping units 110, 120, 130, and 140 may be provided with a shock absorber.

  The present invention is not limited to the above-described embodiments. The present invention has ordinary knowledge in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. It is self-explanatory. Therefore, it should be said that such modifications or variations belong to the claims of the present invention.
