Patent Application
20150083041
The subject matter herein generally relates to a glue applicator.
Sometimes, two elements of an electronic device need to be adhered together during assembly. In a typical glue coating process, a workman dispenses the glue from a glue dispenser, and coats the glue on elements. Then the two elements can be firmly adhered together.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
The present disclosure is described in relation to a glue applicator.
The positioning assembly 50 can include a tray 51 and four positioning blocks 53. The tray 51 can include a limiting block 511, a receiving groove 512 surrounding the limiting block 511, and four recesses 513 surrounding the receiving groove 512. The four recesses 513 can be respectively connected to the receiving groove 512. Each recess 513 can include a first portion 5131 and a second portion 5132, and the first portion 5131 can be positioned between the receiving groove 512 and the second portion 5132. The glue dispenser 200 can be assembled in the first portion 5131, the bottom of the glue dispenser 200 can extend through the receiving groove 512 and resist against the limiting block 511. A nozzle of the glue dispenser 200 can be coupled to the second portion 5132. Each of the four positioning blocks 53 can cross the corresponding first portion 5131, and can be connected to the tray 51 by screws. The positioning blocks 53 can be coupled to the corresponding first portion 5131, which can be configured to fasten the glue dispenser 200 to the tray 51. In at least one embodiment, the positioning blocks and the recesses can be less than, or more than four.
The driving assembly 30 can include a fixing bracket 31 and a driving member 33 assembled to the fixing bracket 31. The driving member 33 can include a main body 331 and a driving shaft 332 connected to the main body 331.
Each positioning block 53 can include a limiting slot 531 adjacent to the glue dispenser 200 (see
The four supporting assemblies 70 can be respectively assembled to the corresponding mounting hole 133 of the mounting plate 13, and include a second bracket 71 and a rotating wheel 73. The second bracket 71 can be assembled in the mounting hole 133, and part of second bracket 71 can extend beyond the mounting plate 13. The rotating wheel 73 can be rotatable and assembled to the second bracket 71, and resist the tray 51. When the tray 51 rotates relative to the bracket 10, the rotating wheel 73 can rotate relative to second bracket 71. The rotating wheel 73 can also be configured to support the tray 51, which can improve the stability of the tray 51.
In operation, the glue dispenser 200 can be assembled in the corresponding recess 513, and the nozzle of the glue dispenser 200 can be received in the second portion 5132 of the recess 513. The positioning block 53 can be attached to the tray 51, so the glue dispenser 200 can be firmly clamped between the recess 513 and the positioning block 53. The tray 51 can rotate driven by the main body 331, and create centrifugal force. The centrifugal force can move the glue to the nozzle of the glue dispenser 200, and the bubbles in the glue dispenser 200 move to the bottom of the glue dispenser 200.
The tray 51 can be rotated and form centrifugal force, the glue dispenser 200 can also rotate along with the tray 51. The bubbles can be separated from the glue in the glue dispenser 200 by centrifugal force. The glue emitted from the glue dispenser 200 is free of bubbles, which can improve the adhesion strength of the glue.
The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of a glue applicator. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure up to, and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
