The present invention relates to an adjustable tray holder assembly.

  Since the downsizing and high performance of electronic devices are accelerating, the manufacturing technology of high performance microminiature electronic components is very important. Electronic parts that are produced in large quantities may be packaged and sold in parts. However, manufacturers of electronic equipment perform a process of putting a large quantity of electronic parts into a component mounting device, so a large number of electronic parts are manufactured. In some cases, parts are packaged in trays.

  In the process of packaging a large number of electronic components in a tray, it is necessary to take out defective products of electronic components and package them in a state of being accurately aligned in the tray, so an automated electronic component packaging device is used. . In the electronic device packaging apparatus, after sorting only non-defective products other than defective products, the sorted electronic components are loaded on a tray.

  The tray is an accessory used in the final packaging process of the electronic components, and must be able to accommodate a large number of electronic components in a correct posture. The tray is manually or automatically placed in a tray holder installed in the electronic device packaging apparatus.

  Since vibration is generated during the operation of the electronic component packaging apparatus, the tray must be stably supported by the tray holder in order to prevent the electronic components loaded on the tray from being displaced.

  FIG. 9 is a perspective view of a conventional tray holder assembly.

  The conventional tray holder assembly shown in FIG. 9 has a tray holder (5) in which a tray (3) is disposed. The tray holder (5) is coupled to a movable plate (7) that is movably mounted on the guide rail (2). That is, the tray holder (5) that supports the tray (3) can move along the guide rail (2).

  One end of the tray (3) disposed in the tray holder (5) is supported by a jaw (4) fixedly installed on the tray holder (5). A tray support bar (6) that supports the other end of the tray (3) is installed in the tray holder (5). The tray support bar (6) is attached to the tray holder (5) by bolts (6a) at positions corresponding to the vertical and horizontal widths (Xd, Yd) of the end region of the tray (3) arranged in the tray holder (5). Fixed to.

  However, in the configuration of the tray holder assembly as shown in FIG. 9, in order to support the tray (3b) whose size has been changed from the tray (1), the tray (3b) whose size has been changed is stably used. Another tray holder (5b) with a tray support bar (8) fixed to form different widths (Xd ′, Yd ′) by means of bolts (8a) to support must be used. Thus, conventionally, since tray holders having different sizes must be provided in accordance with changes in the tray size, it is difficult to manage the tray holders, and inconvenience that requires time and work personnel to replace the tray holders. Exists.

  Also, conventionally, as an improvement of the tray holder assembly of FIG. 9, the bolt (6a) securing the tray support bar (6) is moved to overcome the inconvenience of having tray holders with different and different sizes. A method of arranging a long hole through which the bolt (6a) can pass through the tray holder (5) has been devised. If this method is used, the fixing position of the tray support bar (6) can be changed according to the size of the tray (3) being changed, but the bolt (6a) is attached as in the case of FIG. After removing and moving the fixing position of the tray support bar (6), it is necessary to perform an inconvenient operation such as re-fastening the bolt (6a).

The fixed support portion (378) includes a first fixed support portion (378a) and a second fixed support portion (378b) that respectively support the opposite ends of the tray set (379).

  An intermediate support portion (380) is disposed between adjacent trays (371). Referring to FIG. 7, the intermediate support part (380) is coupled to the magnetic attachment part (381) attached to the tray holder (375) between the adjacent trays (371) and the upper surface of the magnetic attachment part (381). The cover portion (382) protruding toward the tray (371) on the outside of the magnetic attachment portion (381) and the groove (382a) formed in the cover portion (382) are disposed at the end of the tray (371). A plurality of support balls (383) in contact with the upper surface (371d) of (371b).

  Referring to FIG. 8, the main body of the magnetic attachment portion (381) can be formed of a nonmagnetic metal material such as plastic, rubber, or aluminum, and an attachment hole (381d) formed in the magnetic attachment portion (381). A magnet portion (389) is inserted into each of the two. Therefore, the magnetic attachment portion (381) (intermediate support portion (380)) can be attached to the tray holder (375) by magnetic force, as well as the tray support portion (377), and the tray holder (375) by the operator's force. It can also be separated from

  A cover part (382) is installed on the top surface of the magnetic attachment part (381). The cover portion (382) has a hole (382f) through which the bolt (385) passes. Further, the cover part (382) includes a groove (382a) formed to extend along the magnetic attachment part (381) in a portion protruding outward from the magnetic attachment part (381). A plurality of support balls (383) are disposed in the groove (382a) of the cover portion (382). The groove (382a) has a size that can support the support ball (383) so that the support ball (383) rotates.

  An elastic plate (384) can be disposed on the upper surface of the cover portion (382). Since the elastic plate (384) also includes a hole (384d) through which the bolt (385) passes, the bolt (385) passes through the hole (384d) of the elastic plate (384) and the hole (382f) of the cover portion (382). And coupled to the screw groove (381f) of the magnetic attachment portion (381). That is, the elastic plate (384) and the cover part (382) are coupled to the magnetic attachment part (381) by the bolt (385).

  The elastic plate (384) includes an exposure hole (384a) that is formed at a position corresponding to the groove (382a) of the cover portion (382) and exposes a part of the support ball (383) to the top. The elastic plate (384) is deformed like a spring by the pressure of the support ball (383) in a state where it is coupled to the cover portion (382) by a bolt (385), thereby being applied by the support ball (383). The pressure can be buffered.

  Referring to FIG. 7, the upper end opening (382c) of the groove (382a) of the cover part (382) is formed larger than the diameter of the support ball (383). On the other hand, the size of the exposed hole (384a) of the elastic plate (384) on the upper surface of the cover part (382) is smaller than the diameter of the support ball (383).

  Further, since the lower end opening (382b) of the groove (382a) of the cover part (382) is formed smaller than the diameter of the support ball (383), the support ball (383) is formed in the groove (382a) of the cover part (382). ) Is inserted, a portion of the support ball (383) protrudes downward from the lower end opening (382b) of the groove (382a) by a predetermined length due to the action of gravity. Therefore, if the elastic plate (384) is not provided on the upper surface of the cover part (382), the support ball (383) is detached to the upper side of the cover part (382) through the upper end opening (382c) of the groove (382a).

  However, in the state as shown in FIG. 7, only a part of the support ball (383) that the upper surface (371d) of the end portion (371b) of the tray (371) pushes upward is formed on the elastic plate (384). It protrudes upward by the exposure hole (384a) and presses the elastic plate (384) upward.

  The intermediate support portion (380) configured as described above can stably support the end portion (371b) of the adjacent tray (371). That is, each of the plurality of trays (371) has manufacturing tolerances or wear and deformation due to long-term use of the tray (371), thereby causing an end portion of the adjacent tray (371) ( The height of 371b) may not match exactly. In such a case, the state in which the tray (371) is disposed in the tray holder (375) becomes unstable.

  However, in the tray holder assembly (370) configured as described above, the support ball (383) of the intermediate support portion (380) presses the end portion (371b) of the tray (371) downward, so that there is a gap between the trays (371). The instability caused by the difference in dimensions can be eliminated.

  For example, when the height of the end portion (371b) of the adjacent tray (371) is different due to deformation of the tray (371) or the like, one of the end portions (371b) of the tray (371) protrudes upward. The support ball (383) is pressurized. In this case, since the elastic plate (384) of the intermediate support portion (380) is elastically deformed and the applied pressure of the support ball (383) protruding upward can be buffered, the end of the adjacent tray (371) can be buffered. Even when the portions (371b) have different heights, they can be stably supported.

  The description of the configuration and effects of the above-described embodiments is merely illustrative, and various modifications and equivalent other embodiments can be realized by those having ordinary knowledge in the art. Should be understood. Accordingly, the true technical protection scope of the present invention should be determined by the appended claims.
