Abstract

A stacking and aligning device is used for aligning a plurality of objects in a stacking area and comprises a base, a fixed column, a moving piece, a connecting rod mechanism group and an aligning component. The fixed column is arranged on the base, and the moving piece is connected to the fixed column and can move relative to the fixed column along the long axis of the fixed column in an operation and control mode. The linkage mechanism set can be operated and controlled to act relative to the moving member. The aligning component is pivoted to the connecting rod mechanism set and is used for pushing one of the objects. When the connecting rod mechanism group acts, the aligning component is driven by the connecting rod mechanism group to synchronously move and is not driven by the connecting rod mechanism group to synchronously rotate, so that the aligning component can simultaneously perform two axial aligning actions on the object under the condition of not changing the seat direction.

Description

Stacking and aligning device and aligning method thereof

Technical Field

The present invention relates to an alignment apparatus and an alignment method thereof; in particular to an alignment device for articles when they are stacked longitudinally and an alignment method thereof.

Background

In the manufacturing stage, the robot arm transfers the workpieces one by one to be stacked in a stacking area, and in order to avoid the non-aligned stacking relationship between adjacent workpieces, an alignment device is used to stack the workpieces in the stacking area in order.

For example, the conventional aligning apparatus includes a first aligning mechanism movable along the X-axis and the Z-axis, and a second aligning mechanism movable along the Y-axis and the Z-axis. When a machine arm transfers a workpiece to be stacked in the stacking area, the Z axial directions of the first aligning mechanism and the second aligning mechanism are controlled to align with the position of the workpiece, then the first aligning mechanism can push the workpiece along the X axial direction, the workpiece is aligned in the stacking area along the X axial direction, the second aligning mechanism can push the workpiece along the Y axial direction in sequence, and the workpiece is aligned in the stacking area along the Y axial direction. The steps are continuously repeated until the workpieces are orderly stacked in the stacking area.

However, the conventional alignment device cannot simultaneously perform the alignment operation in the X-axis direction and the Y-axis direction on the plurality of objects, and the number of workpieces is large, which results in poor efficiency of aligning the workpieces.

Disclosure of Invention

In view of the above, the present invention is directed to a stacking and aligning apparatus, which can improve the efficiency of stacking and aligning workpieces.

In order to achieve the above objects, the present invention provides a stacking and aligning device for aligning a plurality of objects in a stacking area, the stacking and aligning device includes a base, a fixing column, a moving member, a linkage assembly, and an aligning member.

The fixing column is arranged on the base, and the long axis direction of the fixing column is vertical to a horizontal plane of the base; the moving member is connected to the fixed column and can move relative to the fixed column along the long axis direction of the fixed column under control, the moving member is provided with an extending table, and the extending table extends towards an extending direction perpendicular to the long axis direction of the fixed column.

The connecting rod mechanism set comprises a first moving assembly, a second moving assembly and a connecting rod, wherein the first moving assembly is parallel to the second moving assembly, the first moving assembly and the second moving assembly are pivoted on the extension table, and the connecting rod is connected with the first moving assembly and the second moving assembly. The linkage mechanism set can be operated and moved relative to the extension table. The aligning component is pivoted to the connecting rod mechanism set and is used for pushing one of the objects. When the link mechanism group acts, the alignment assembly is driven by the link mechanism group to synchronously move and is not driven by the link mechanism group to synchronously rotate.

The present invention also provides a method for aligning objects in the stacking and aligning apparatus, which comprises the following steps:

the first step is as follows: a first object is placed in a stacking area.

The second step is as follows: and placing a second object on the first object, wherein the projection outline and the projection area of the second object and the projection area of the first object in the stacking area are the same, but the projection of the second object is not completely overlapped with the projection of the first object.

The third step: and rotating the first moving assembly to enable the long axis of the first moving rod to be parallel to an alignment direction. The alignment direction is a turning angle of the alignment assembly and a straight line direction of a corner of the first object. When the first moving assembly rotates under the control of the operation, the first moving assembly drives the second moving assembly to synchronously rotate through the connecting rod;

the fourth step: and moving the first moving assembly, driving the second moving assembly to synchronously move in the same direction by the first moving assembly through the connecting rod, driving the aligning assembly by the first moving assembly and the second moving assembly, and then pushing the second object by the aligning assembly until the projection of the second object is completely overlapped with the projection of the first object.

The invention has the advantages that the connecting rod mechanism group drives the aligning component to move synchronously without changing the seat direction of the aligning component, and the connecting rod mechanism group can enable the aligning component to move obliquely, namely, two axial moving alignments are carried out simultaneously, so that the efficiency of aligning the plurality of objects is improved.

first step S1: placing a first object 20 in the stacking area A;

second step S2: placing a second object 202 on the first object 201, wherein the projection outline and the projection area of the second object 202 and the first object 201 in the stacking area A are the same, but the projection of the second object 202 does not completely overlap with the projection of the first object 201;

third step S3: rotating the first moving assembly 42 to make the long axis of the first moving rod 442 parallel to the alignment direction D;

fourth step S4: when the first moving assembly 42 is moved, the first moving assembly 42 drives the second moving assembly 44 to synchronously move in the same direction through the connecting rod 46, the first moving assembly 42 and the second moving assembly 44 drive the aligning assembly 50, and then the aligning assembly 50 pushes the second object 202 until the projection of the second object 202 completely overlaps the projection of the first object 201.

In a first step S1, please refer to fig. 7, if the corner C2 of the first object 201 deviates from the corresponding corner of the stacking area a too much, the following operations are performed. Referring to fig. 8, the first positioning element 424 is controlled by the second driving device 70 to rotate, and the first positioning element 424 drives the first moving rod 422 of the first moving assembly 42 to synchronously rotate in the same direction, so that the long axis of the first moving rod 422 is parallel to the aligning direction D. When the first moving rod 422 rotates, the first moving rod 422 drives the second moving rod 442 of the second moving assembly 44 to synchronously rotate via the connecting rod 46, and when the second moving rod 442 rotates, the second moving rod 442 drives the second positioning member 444 of the second moving assembly 44 to synchronously rotate in the same direction. Then, the first moving rod 422 is operated by the third driving device 80 to move forward, the first moving rod 422 drives the second moving rod 442 to move synchronously in the same direction through the connecting rod 46, and the first moving rod 422 and the second moving rod 442 drive the aligning assembly 50. Referring again to fig. 9, the aligning member 50 pushes the first object 201 until the center of the first object 201 projected on the plane formed by the first axis Y and the second axis X completely overlaps the center of the stacking area a. More specifically, during the pushing of the first object 201 by the aligning member 50, the first aligning surface 52a of the aligning member 50 is attached to the edge of the corner C2 of the first object 201 corresponding to the first side a1, and the second aligning surface 54a is attached to the edge of the corner C2 of the first object 201 corresponding to the second side a 2.

In a second step S2, when the second object 202 is placed on the first object 201, as shown in fig. 10, the moving member 30 is operated by the first driving device 60 to drive the link mechanism set 40 and the aligning assembly 50 to move upward along the long axis of the fixed post 20, so that the first aligning plate 52 and the second aligning plate 54 correspond to the second object 202 in the third axis Z.

Referring to fig. 11 and 12, the first positioning element 424 drives the first moving assembly 42 to rotate synchronously in the same direction, so that the long axis of the first moving rod 422 is parallel to the alignment direction D. More specifically, the alignment direction D passes through the turning angle C1, the corner C2 of the first object 201 and the corner C3 of the second object 202 to stop the rotation of the second driving device 70. When the first moving rod 422 rotates, the first moving rod 422 drives the second moving rod 442 of the second moving assembly 44 to synchronously rotate through the connecting rod 46, and when the second moving rod 442 rotates, the second moving rod 442 drives the second positioning member 444 of the second moving assembly 44 to synchronously rotate in the same direction.

In the fourth step S4, the first moving element 42 is moved forward by the third driving device 80, the first moving rod 422 drives the second moving rod 442 to move synchronously in the same direction through the connecting rod 46, the first moving rod 422 and the second moving rod 442 drive the aligning element 50, and referring to fig. 12, the aligning element 50 pushes the second object 202 until the projection of the second object 202 on the plane formed by the first axial direction Y and the second axial direction X completely overlaps the projection of the first object 201, i.e. the turning angle C1, the corner C2 of the first object 201, and the corner C3 of the second object 202 overlap to a point. More specifically, during the pushing of the second object 202 by the alignment assembly 50, the first alignment surface 52a of the alignment assembly 50 is attached to one side of the corner C3 of the second object 202, and the second alignment surface 54a is attached to the other side of the corner C3 of the second object 202.

Through the first step S1 to the fourth step S4, the remaining objects 200 are arranged in the stacking region a in order, and the projections of the objects 200 on the plane formed by the first axial direction Y and the second axial direction X are all overlapped, so as to achieve the alignment effect. It should be noted that each of the objects 200 may also be formed by a plurality of small elements, for example, four, six or eight small elements, and the small elements in each of the objects 200 are placed in the stacking area a in a manner of being close to each other through the first step S1 to the fourth step S4.

In addition, the method for aligning objects in the present embodiment may further optionally include the following steps:
