1. Technical Field
The present disclosure generally relates to devices for separating workpieces.
2. Description of related art
Electronic devices (such as mobile phones) comprise many workpieces. During an assembling process of the electronic devices, the workpieces need to be evenly spaced apart from each other to facilitate assembly. However, devices for separating workpieces can not always effectively or rapidly separate the workpieces.
Therefore, there is room for improvement within the art.
Many aspects of the disclosure can be better understood with reference to the drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the views.
The driving unit 10 includes a driver 12, a gear 14 driven by the driver 12, and a rack 16 engaging with the gear 14. The driver 12 can be a motor, for example, and is attached to the supporting board 20. The rack 16 is slidably assembled to the supporting board 20. The driver 12 drives the gear 14 to rotate, thereby driving the rack 16 to slide relative to the supporting board 20. The rack 16 includes a fastening portion 161. The fastening portion 161 defines two first threaded holes 1612. The fastening portion 161 is connected to the moving assembly 30
The supporting board 20 is substantially rectangular. Two sliding rails 22 are attached to a first surface of the supporting board 20 and are located at two ends of the supporting board 20. The two sliding rails 22 are substantially parallel to each other. The supporting board 20 defines a through hole 24 and a plurality of sliding grooves 26. The through hole 24 extends along a direction substantially parallel to the two sliding rails 22. The direction parallel to the two sliding rails 22 is defined as a first direction. The fastening portion 161 of the rack 16 extends through the through hole 24 from a second surface of the supporting board 20 opposite to the first surface, to be attached to the moving assembly 30 and slide in the through hole 24 along the first direction. When the rack 16 is driven to move, the fastening portion 161 slides in the through hole 24 to move the rack 16 and the moving assembly 30.
The plurality of sliding grooves 26 are symmetrically located at two sides of the through hole 24 and are defined in the first surface of the supporting board 20. In this embodiment, each side of the through hole 24 has three sliding grooves 26. Each sliding grooves 26 extends at an angle relative to the through hole 24. The sliding grooves 26 and the through hole 24 are evenly spaced apart from each other. Angles formed between the through hole 24 and the two adjacent sliding grooves 26, as well as angles formed between two adjacent sliding grooves 26, are substantially the same. A direction perpendicular to the through hole 24 is defined as a second direction. That is, a distance between each two adjacent sliding grooves 26 and a distance between the through hole 24 and the two adjacent sliding grooves 26 along the second direction increases linearly from a first end of the sliding grooves 26 to an opposite second end of the sliding grooves 26, or decreases linearly from the second end of the sliding grooves 26 to the first end of the sliding grooves 26.
The moving assembly 30 includes two sliding blocks 31, a sliding board 32, a plurality of moving blocks 34, and two fastening bars 36.
Each sliding block 31 defines a sliding recess 312. The two sliding blocks 31 are attached to two ends of the sliding board 32. Each sliding rail 22 of the supporting board 20 is slidably received in a corresponding sliding recess 312, thereby enabling the sliding board 32 to slide relative to the supporting board 20. The sliding board 32 is attached to the fastening portion 161 of the rack 16 to allow the rack 16 to drive the sliding board 32 to slide. In the exemplary embodiment, the sliding board 32 defines two spaced second threaded hole 321 corresponding to the two first threaded holes 1612 of the rack 16. The first and second threaded holes 1612, 321 are configured for receiving screws therein, thereby securing the sliding board 32 to the rack 16. The sliding board 32 defines two spaced latching holes 325, thereby forming a fixing portion 323 between the two latching holes 325. The two second threaded holes 321 are defined in the fixing portion 323. Each latching hole 325 is a through hole and extends along a direction substantially perpendicular to the through hole 24. Each latching hole 325 has a length long enough not to limit the movement of the moving blocks 34.
The moving blocks 34 include a plurality of first moving blocks 34a and a second moving block 34b. A number of the plurality of first moving blocks 34a is the same as a number of the sliding grooves 26. Each first moving block 34a has a roller 341 attached to an end thereof. The first moving blocks 34a extend through the latching holes 325, with the roller 341 of each first moving block 34a slidably received in one of the sliding grooves 26, such that the first moving blocks 34a are capable of sliding along the sliding grooves 26. The second moving block 34b is secured to the fixing portion 323. An opposite end of each moving block 34 has a mechanism 342 for holding workpieces 200 to be separated. The mechanism can be a vacuum grip device, for example. Each moving block 34 has a flange 343 protruding from opposite sides.
Each fastening bar 36 defines a latching recess 361. The two fastening bars 36 are attached to the sliding board 32 with the moving blocks 34 located between the two fastening bars 36. The flanges 343 of the moving blocks 34 extend in the latching recesses 361 for latching the moving blocks 34 in the two fastening bars 36 and ensuring that the rollers 341 slide in the sliding grooves 26.
In use, referring to
In other embodiments, the second moving block 34b can be omitted and just use the first moving blocks 34a to hold workpieces as long as adjacent sliding grooves 26 have substantially the same angle between each other.
In other embodiments, the plurality of sliding grooves 26 may be other shapes or sizes, or other guiding mechanism for guiding the first moving block 34a to move along the first direction. Such a guiding mechanism is defined as a first guiding mechanism. For example, a number of the sliding grooves 26 may be more or less, and the sliding grooves 26 may be spaced differently according to the workpieces. The plurality of sliding grooves 26 may be arcuate, as long as the workpieces are separated from each other when the first moving blocks 34a slide along the sliding grooves 26. Additionally, the two latching holes 325 may also be other shapes or sizes, or other guiding mechanism for guiding first moving blocks 34a to move along the second direction perpendicular to the first direction when the first moving blocks 34a are forced to move along the first guiding mechanism. Such a guiding mechanism is defined as a second guiding mechanism. For example, a number of the latching holes 325 may be more or less, and the latching holes 325 may be spaced differently, according to the workpieces.
It is to be understood, however, that even through numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of assembly and function, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
