For example, a process, method, system, article, or apparatus that comprises a list of steps or modules is not limited to only those steps or modules but may include other steps or modules not expressly listed or inherent to such process, method, article, or apparatus.

In one aspect, referring to fig. 1 to 4, the present embodiment provides a workpiece alignment device, which includes a table 10 and an alignment assembly 20. The alignment assembly 20 is disposed on the workbench 10, the alignment assembly 20 includes an assembly body 201 and an alignment member 202 that are connected to each other, and in an operating state, the alignment member 202 is fixed relative to the assembly body 201. The assembly body 201 is configured to be limited relative to the workbench 10 in a first direction, a specific limiting manner may adopt a limiting mechanism to limit, and an exemplary limiting mechanism may adopt a limiting groove, a limiting boss or the like arranged on the workbench 10, and when the limiting groove or the limiting boss is adopted, the limiting groove or the limiting boss is arranged along a second direction, and the second direction is mutually perpendicular to the first direction. The module body 201 is movable only in a second direction perpendicular to the first direction on the table 10 when the first direction is limited to the table 10. In the second direction, the force is applied to the acting surface of the workpiece 2 in the process of moving the alignment member 202 relative to the workpiece 2, so as to restrict the acting surface of the workpiece 2 and the moving track of the alignment member 202 to be overlapped or parallel, and the force application strength is kept constant, so that the straightness of the acting surface of the workpiece 2 in the second direction is kept consistent.

The first direction is a direction parallel to or coincident with the reference plane on which the table 10 is located, and includes a direction pointing to another point from the origin and a direction opposite thereto. The second direction is similar to the first direction, and is a direction parallel to or coincident with the reference plane on which the table 10 is located, and includes a direction pointing at another point with the origin and a direction opposite thereto.

Through the arrangement in the embodiment, the labor intensity of operators can be effectively reduced, the operation process is simple, and the working efficiency is high.

In some embodiments, referring to fig. 5 to 8, the alignment member 202 is configured to be movably retained on the assembly body 201 relative to the assembly body 201, and the movement direction of the alignment member 202 relative to the assembly body 201 is a first direction. The alignment member 202 is retained on the assembly body 201, i.e. the alignment member 202 does not disengage from the assembly body 201. The alignment member 202 is fixed relative to the assembly body 201 in the working state of the alignment assembly 20, so that the alignment member 202 can keep applying force to the working surface of the workpiece 2 during the movement of the alignment assembly 20 along the second direction. The alignment member 202 may move relative to the assembly body 201, mainly corresponds to a non-working state of the alignment assembly 20, such as a preparation stage, and for the workpieces 2 with different sizes in the first direction, the position of the alignment member 202 in the first direction needs to be correspondingly adjusted, so that the alignment member 202 applies a force to the acting surface of the workpiece 2, and then the alignment assembly 20 adjusts the straightness of the workpiece 2 along the second direction in the process of moving in the second direction, so as to realize the alignment function of the workpiece 2. The above embodiment can align the workpieces 2 of different sizes in the first direction, improving the adaptability of different workpieces 2.

In some embodiments, the alignment member 202 is configured to be movably retained on the assembly body 201 in a third direction relative to the assembly body 201, wherein the third direction is perpendicular to the first direction and the second direction, respectively, i.e., the third direction is perpendicular to the plane of the table 10. Illustratively, the alignment member 202 is fixed relative to the assembly body 201 in the operative state of the alignment member 202; in the non-working state, particularly in the preparation stage, the position of the alignment member 202 in the third direction is adjusted so that the alignment member 202 keeps applying force to the acting surface of the workpiece 2, thereby adaptively aligning the workpieces 2 with different height dimensions.

In some examples, when the alignment member 202 applies a force to the acting surface of the workpiece 2, in order to ensure that the straightness of the workpiece 2 in the second direction is kept consistent in the constrained process, a limiting component may be disposed on an opposite side of the acting surface of the workpiece 2, where the limiting component may be a component body 201 of the alignment component 20, or may be another component disposed on the workbench 10, that is, in the process that the alignment member 202 constrains the workpiece 2, the workpiece 2 is clamped by the alignment member 202 and the limiting component, so as to complete adjustment of the straightness of the workpiece 2 in the second direction.

In other examples, the limiting component may not be provided, and when the self weight of the workpiece 2 reaches a certain degree, the alignment member 202 restrains the workpiece 2, and other areas except the area where the acting surface is stressed are not affected by the alignment member 202, so that the rotation is avoided, and the adjustment of the straightness of the workpiece 2 in the second direction is further realized.

In some examples, referring to fig. 9, the alignment member 202 includes a bracket 2025 and an alignment portion. Wherein, the bracket 2025 is provided with a first chute 20251 along a first direction; the alignment portion includes a bolt 2021 and a nut 2022, the first chute 20251 may employ a through slot, and the bolt 2021 head and the nut 2022 are respectively disposed at opposite ends of the opening of the first chute 20251. The bolt 2021 and the nut 2022 are adjusted to fix or move the alignment portion with respect to the bracket 2025. When the fixing is required, the nut 2022 is screwed down to complete the fixing of the alignment part relative to the bracket 2025, when the alignment part is required to be adjusted to move in the first direction relative to the bracket 2025, the nut 2022 is unscrewed, then the whole alignment part is moved relative to the bracket 2025, and after the position is adjusted, the nut 2022 is screwed down again to complete the fixing. On the other hand, in the working process of the alignment member 202, the bolt 2021 contacts with the workpiece 2, so as to keep applying force to the acting surface of the workpiece 2, and in the moving process along the second direction, the acting surface of the workpiece 2 is restrained to be overlapped or parallel to the moving track of the alignment member 202, so that the straightness of the workpiece 2 along the second direction is adjusted, and the purpose of aligning the workpiece 2 is achieved.

In some of these embodiments, a rotational bearing 2023 may be provided on the bolt 2021, and the rotational bearing 2023 may be rotatably held on the bolt 2021. In the operating state of the alignment member 202, the outer side wall of the pivot bearing 2023 contacts the working surface of the workpiece 2, and keeps applying force to the working surface of the workpiece 2. Because the contact part between the outer side wall of the rotating bearing 2023 and the workpiece 2 is arc-shaped, the contact surface between the rotating bearing 2023 and the workpiece 2 is smaller, the time for the alignment member 202 to contact any specific position of the workpiece 2 in the process of moving relative to the workpiece 2 is shorter, and the rotating bearing 2023 is rotatable relative to the bolt 2021, so that the friction time between the corresponding two parts is shorter, and further the friction damage to the workpiece 2 can be effectively avoided. In other examples, the alignment portion may contact the workpiece 2 with an arcuate surface, a planar surface, or the like. The alignment part can also adopt modes such as an alignment block, an alignment column and the like.

In other embodiments, the alignment member 202 may be movably connected with the first alignment member and the second alignment member, such as by bonding, clamping, or the like. The alignment member 202 keeps the first alignment sub-member fixed relative to the second alignment sub-member in the working state, and makes the first alignment sub-member or the second alignment sub-member apply a force to the working surface of the workpiece 2. In the preparation phase, the first alignment sub-part is adjusted to be loose relative to the second alignment sub-part so as to adjust the position of the first alignment sub-part or the second alignment sub-part in the first direction to adapt to workpieces 2 with different sizes.

In some examples, referring still to fig. 5 and 6, a second chute 2011 is provided on the assembly body 201 along the third direction, and one end of the bracket is disposed in the second chute, so that the bracket is slidably connected with the assembly body. The workpiece alignment device further includes a fixing piece 30, the bracket 2025 is provided with a threaded through hole 20252 along the first direction, the fixing piece 30 and the bracket 2025 are in threaded connection through the threaded through hole 20252, and the fixing piece 30 abuts against the groove wall of the second chute 2011 in the process of being in threaded connection with the bracket 2025, so that the alignment piece 202 is fixed relative to the assembly body 201 in the third direction. When the position of the alignment member 202 in the third direction needs to be adjusted, the fixing member 30 is unscrewed, so that the contact state of the fixing member 30 and the groove wall of the second chute 2011 is changed into the separation state, and then the alignment member 202 is adjusted relative to the assembly body 201 in the third direction.

In a specific manner of adjusting the movement of the alignment member 202 relative to the assembly body 201 in the third direction, the specific slot shape may be any manner, such as a T-slot, a blind slot, etc., and is not specifically limited herein.

In other examples, a plurality of threaded holes may be formed in the assembly body 201, and then the fixing member 30 is screwed into the corresponding threaded hole in the assembly body 201 through the threaded through hole 20252 in the bracket 2025 by using a screw or bolt 2021, so as to fix the alignment member 202 relative to the assembly body 201; if the position of the alignment member 202 relative to the assembly body 201 needs to be adjusted in the third direction, different threaded holes on the assembly body 201 are selected for corresponding use, so as to realize the position adjustment of the alignment member 202 relative to the assembly body 201 in the third direction.

In some embodiments, the workbench 10 is provided with a first limiting member, the alignment assembly 20 is provided with a second limiting member, and the first limiting member and the second limiting member are mutually matched, so that the alignment assembly 20 is limited relative to the workbench 10 in a first direction, and the first limiting member and the second limiting member can adopt a limiting hole and a limiting column, wherein the limiting hole can be formed in one of the workbench 10 or the alignment assembly 20, and the other limiting column can be formed in the other one of the workbench 10 and the alignment assembly 20.

In some embodiments, the first limiting member is a sliding rail 101, the sliding rail 101 extends along a second direction, the second limiting member is a limiting protrusion 203, and the limiting protrusion 203 may be a bump or a protrusion. When the limit protrusion 203 is placed in the slide rail 101, the position in the first direction is kept constant because the slide rail 101 is extended along the second direction, and at this time, the limit protrusion 203 is limited with respect to the slide rail 101 in the first direction. Under the working state of the alignment assembly 20, the alignment assembly 20 can move along the second direction relative to the sliding rail 101 through the limiting protrusion 203, so as to realize shape constraint on the workpiece 2 along the second direction. When the size of the workpiece 2 is large, the operation is simpler by adopting a mode of moving the alignment assembly 20, and the workpiece 2 is basically motionless relative to the workbench 10, so that the abnormal movement of the secondary position of the workpiece 2 can be avoided, and the misalignment can be avoided.

In some examples, the alignment assembly 20 is provided with at least two limiting through holes 204, the number of the limiting protrusions 203 is the same as that of the limiting through holes 204, the limiting protrusions 203 are arranged in the limiting through holes 204, and the limiting protrusions 203 are connected with the limiting through holes 204 through bearings. When the alignment assembly 20 moves in the sliding rail 101, the limiting protrusion 203 can keep a rotating state, so that friction between the limiting protrusion 203 of the alignment assembly 20 and the sliding rail 101 can be effectively reduced, and friction loss is reduced.

In other embodiments, the alignment assembly 20 is limited at least in the first direction relative to the table 10, for example, the alignment member 202 may be fixedly connected to the table 10, and in the working state of the alignment member 202, the workpiece 2 is moved along the second direction, so that the portion of the workpiece 2 to be aligned sequentially passes through the position of the fixing member 30, and alignment of the workpiece 2 is finally completed.

In some embodiments, referring to fig. 6, a rolling mechanism 205 is disposed on a side of the assembly body 201 adjacent to the table 10, and the rolling mechanism 205 is in contact with the table 10. The embodiment is mainly used in the case that the alignment assembly 20 moves relative to the workbench 10, and in the moving process of the alignment assembly 20, the rolling assembly is in contact with the workbench 10 and keeps rolling, so that the friction force of the alignment assembly 20 relative to the workbench 10 can be effectively reduced, and the friction loss to the workbench 10 is reduced.

In some embodiments, at least one platen 102 is provided on the table 10, and the platen 102 applies force to a side of the workpiece 2 remote from the table 10 to secure at least a portion of the workpiece 2 to the table 10. In the above embodiment, in order to ensure that the corrected workpiece 2 does not shift, the aligned workpiece 2 may be fixed by the pressing plate 102. In a specific example, for the workpiece 2 with a smaller size in the second direction, the pressing plate 102 may be used for fixing after the whole alignment; for the workpiece 2 with larger size in the second direction, in the alignment process, along with the movement of the alignment assembly 20 relative to the workpiece 2 in the second direction, the workpiece 2 is continuously fixed, that is, the alignment assembly 20 moves a distance, the area of the workpiece 2 which is aligned is fixed by adopting one pressing plate 102, then the alignment assembly 20 continues to move, and after a distance of movement, the area of the subsequent workpiece 2 which is aligned is fixed by adopting another pressing plate 102 until the workpiece 2 completes alignment and fixing of all areas in the second direction.

In some of these embodiments, alignment assembly 20 may be fabricated entirely or partially from metallic or organic materials.

In S20, the initial position of the workpiece 2, which is typically an end edge of the workpiece 2 in the second direction, is maintained by adjusting the alignment assembly 20. The manner of applying the force may include direct force and indirect force, and for example, the direct force may employ the alignment member 202 to directly contact a portion of the area of the workpiece 2 to continuously apply the force to the active surface of the workpiece 2. The indirect force application can be performed by indirect contact, such as magnetic force, etc., to apply force to the acting surface of the workpiece 2.

And S30, moving the alignment assembly 20 relative to the workpiece 2 in a second direction so as to restrict the action surface of the workpiece 2 to be overlapped or parallel with the movement track of the alignment member 202. In S30, in the process of moving the alignment assembly 20 relative to the workpiece 2 in the second direction, the alignment assembly 20 may be driven to move, or the workpiece 2 may be driven to move, specifically, when the size of the workpiece 2 in the second direction is larger, the alignment assembly 20 is driven to move more appropriately, mainly according to the specific size of the workpiece 2; when the size of the workpiece 2 in the second direction is small, the alignment assembly 20 or the workpiece 2 can be driven to move; the alignment assembly 20 and the workpiece 2 may also be driven to move relative to each other simultaneously. The acting surface of the workpiece 2 is a stress surface, the workpiece 2 can enable the position of the workpiece to move in the stress process, and the straightness adjustment in the second direction is completed in the position moving process of the workpiece.

In some embodiments, adjusting the alignment assembly 20 such that the alignment member 202 of the alignment assembly 20 maintains a force on the active surface of the workpiece 2 may specifically include the steps of:

s201, the bolt 2021 and the nut 2022 are in a loose state, and the alignment portion is adjusted in position in the first direction. In S201, when the workpiece 2 with different sizes is replaced for alignment, the original alignment portion cannot complete alignment of the initial position of the workpiece 2 due to replacement of the size of the workpiece 2, and the alignment portion needs to be adjusted in the first direction to enable the alignment portion to complete alignment of the initial position, and then the alignment assembly 20 moves in the second direction relative to the workpiece 2. When the alignment part is adjusted, the nut 2022 is unscrewed, at this time, the limiting mode of the alignment part relative to the bracket 2025 by the bolt 2021 and the nut 2022 is damaged, the position of the alignment part can be adjusted in the first direction, and the alignment part is continuously adjusted so as to support the alignment of the initial position of the alignment part.

S202, the acting surface of the workpiece 2 is kept in contact by the adjusting and aligning part. In S202, the alignment portion keeps in contact with the working surface of the workpiece 2, and keeps applying force to the working surface of the workpiece 2.

In some embodiments, the alignment assembly 20 is adjusted such that the alignment member 202 of the alignment assembly 20 maintains a force on the active surface of the workpiece 2, and may specifically include the following steps:

and S203, the fixing member 30 is in a state of being separated from the groove wall of the second chute 2011, and the position of the alignment member 202 is adjusted in the third direction, so that the alignment member 202 contacts the acting surface of the workpiece 2. In S203, when the fixing member 30 is in a disengaged state with the slot wall of the second chute 2011, the alignment member 202 can be freely adjusted relative to the assembly body 201 in the third direction, and the heights of different workpieces 2 placed on the workbench 10 are different, so that the heights of the alignment member 202 need to be adjusted in a targeted manner to achieve alignment of the workpieces 2.

S204, after the alignment member 202 keeps applying force to the acting surface of the workpiece 2, the fixing member 30 is adjusted, so that the fixing member 30 abuts against the groove wall of the second chute 2011 through the threaded through hole 20252, so as to fix the alignment member 202 relative to the assembly body 201 in the third direction.

Note that S201 and S202 are taken as a whole, and are denoted as a first whole; let S203 and S204 be one whole, denoted as a second whole. Wherein the first whole and the second whole can be relatively independent steps, and can be implemented by steps respectively; the alignment member 202 may be sequentially arranged, that is, the second whole may be implemented after the first whole, or may be implemented before the first whole, so as to adjust the position of the alignment member 202 relative to the assembly body 201 in the first direction and the third direction, so as to adapt to alignment of workpieces 2 of different types and sizes.
