     DETAILED DESCRIPTION 
     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.

In at least one embodiment, the positioning blocks and the recesses can be less than, or more than four. 
       FIG. 2  illustrates an exploded, perspective view of the glue applicator. The bracket  10  can include a first bracket  11  and a mounting plate  13  assembled to the first bracket  11 . The first bracket  11  can define a receiving portion  112 . The mounting plate  13  can be substantially rectangular, and include a circular through hole  131  and four mounting holes  133  surrounding the through hole  131 . The through hole  131  can be defined on a center of the mounting plate  13 , and can be connected to the receiving portion  112 . Four mounting holes  133  can be respectively located on the quarter lines of the circular through hole  131 . 
     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  FIG. 1 ). A part of the glue dispenser  200  can be locked in the limiting slot  531 . The limiting slot  531  can be coupled to the corresponding first portion  5131 , and the glue dispenser  200  can be clamped between the limiting slot  531  and the first portion  5131 . 
     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 . 
       FIG. 3  illustrates a cross-sectional, perspective view of the glue applicator. The driving assembly  30  can be connected to the mounting plate  13 .

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.
