Specific implementation mode
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation describes.Obviously, described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, the every other implementation that those skilled in the art are obtained without creative efforts
Example, shall fall in the protection scope of this application.
Refering to fig. 1 to Fig. 3, in LED display point glue equipment of the present invention, including pedestal 10, pressure exerting arrangement 11, packing element 12,
Glue dripping head 13 and heating mechanism 14.
Wherein, Glue dripping head 13 includes receiving cavity 131 and glue mouth 132, and gold may be used in receiving cavity 131 and nozzle 132
Belong to material to be made.As shown, receiving cavity 131 is mounted on one end of pedestal 10, glue mouth 132 is connected to receiving cavity 131.
Packing element 12 is mounted in a side of pedestal 10, and position is higher than the position of receiving cavity 131 for storing glue.
Packing element 12 is connected to by sebific duct 121 with receiving cavity 131.
Pressure exerting arrangement 11 such as can be air pressure mechanism in the form of piston, be connected by tracheae 111 and packing element 12.Pressure exerting arrangement
11 to the glue in packing element 12 for applying air pressure, so that the glue in packing element 12 is under pressure, is squeezed from packing element 12
It is depressed into a receiving cavity 131, and is squeezed out from glue mouth 132, to realize the plastic emitting of point glue equipment.
Wherein, in the present embodiment, heating mechanism 14 is mounted in receiving cavity 131, for the glue in receiving cavity 131
Water carries out being heated to target temperature, is heated as a result, to the glue in receiving cavity 131 by heating mechanism 14, Ke Yiti
The temperature of high glue, and then improve the mobility of glue so that mobility bigger when glue is squeezed out from glue mouth 132, it can
It reduces dispensing process and phenomena such as drawing glue, kiss-coating occurs.
Wherein, pedestal 10 is, for example, mechanical arm, is connect with host computer, by the movement of PC control mechanical arm, thus
Packing element 12 and Glue dripping head 13 is driven to move.
It, can be with after LED light 40 is mounted on circuit board 41 as shown in figure 4, in the production process of LED display
Dispensing is carried out using gap of the point glue equipment of the embodiment of the present invention between LED light 40, LED light 40 is preferably fixed on
On circuit board 41.Wherein, by the way that heating mechanism 14 is arranged in receiving cavity 131, with to the glue that will squeeze glue discharging mouth 132
It is heated, the mobility of glue can be improved, to enable to glue to be easier to flow when glue spots are between LED light 40
To the edge of LED light 40, LED light 40 and circuit board 41 are fixed, are conducive to the fastness for improving LED light 40, wherein
Fig. 1 and shown in Fig. 4 42 is glue layer.
Wherein, target temperature such as can be 50 ° or 55 °, 60 ° etc., can specifically be set according to the property of glue
It is fixed.Wherein, it is provided with temperature sensor in heating mechanism 14, the temperature for detecting glue, when detecting in receiving cavity 131
The temperature of glue when being greater than or equal to target temperature, heating mechanism 14 stops heating, avoids glue temperature excessively high, when detecting
When the temperature of glue is less than target temperature, is heated, avoid glue temperature too low and lack mobility.
Certainly, can also be the heating mechanism when detecting that the temperature of glue is less than 40 ° in some other embodiment
14 are heated, and when detecting that the temperature of glue is higher than 50 °, heating mechanism 14 stops heating, and the temperature of glue is ensured with this
In 40 to 50 ° of range.
Wherein, heating mechanism 14 can be such as infrared heating mechanism or electromagnetic heating mechanism, not limit this.
Wherein, in order to more accurately obtain the temperature of glue, as shown in Figure 1, heating mechanism 14 can be arranged in accommodating chamber
The interior bottom of body 131.Certainly, heating mechanism 14 can also be arranged on the madial wall of receiving cavity 131, or can pass through
Connecting rope is suspended on the middle part of receiving cavity 131.
Further, with continued reference to Fig. 1, point glue equipment further includes light source 15 and camera 16.Light source 15 and camera 16
It is installed on pedestal 10.Wherein, packing element 12 is located on the side of pedestal 10, and light source 15 and camera 16 are then located at pedestal 10
The other side opposite with packing element 12 on.Wherein, packing element 12 can be the side positioned at 13 moving direction of Glue dripping head, such as to scheme
Based on view shown in 1, the Glue dripping head 13 of point glue equipment is moved from left to right to carry out dispensing, the i.e. mobile side of Glue dripping head 13
To for the right, packing element 12 is arranged on the right of pedestal 10, and light source 15 and camera 16 are then arranged on the left side of pedestal 10.
Wherein, the camera lens 161 of camera 16 is towards the direction where Glue dripping head 13, in dispensing to circuit board 41 into
Row is taken pictures, to which host computer obtains the photo captured by camera 16, to go out (the marks of the mark on circuit board 41 according to photo array
Note) point, which is start reference coordinate for dispensing glue.Light source 15 is between camera lens 161 and Glue dripping head 13, when needs pass through
When camera 16 takes pictures to position circuit board 41, light source 15 is opened to irradiate circuit board 41, in the light of light source 15
Under irradiation, camera 16 can obtain clearer mark points photo, the accuracy of mark point locations can be improved, to improve
The accuracy of dispensing position.
Refering to Fig. 5, in another embodiment of point glue equipment of the present invention, point glue equipment can also include further that distance passes
Sensor 17.Range sensor 17 is connect with host computer, is arranged on glue mouth 131, for obtain glue mouth 131 and circuit board 41 it
Between distance.Host computer is less than the direction movement that threshold value time control glue mouth 131 is directed away from circuit board 41 in the distance.
During dispensing, when the distance between glue mouth 131 and circuit board 41 are smaller, it is possible to glue mouth 131 can be caused
Touch circuit board 41 either LED light 40 in order to avoid glue mouth 131 touches circuit board or LED light and scratch circuit board or
LED light, and also to avoid glue mouth 131 from damaging, by the way that a threshold value is arranged, when detecting between glue mouth 131 and circuit board 41
Distance be less than when changing threshold value, then control glue mouth 131 and move up, that is, the direction movement of circuit board 41 is directed away from, to increase
The distance between glue mouth 131 and circuit board 41.
Mode the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this
Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content, it is relevant to be applied directly or indirectly in other
Technical field is included within the scope of the present invention.
