The SMT painting device is characterized by being mainly composed of a driving power source, piezoelectric ceramics, a nozzle and an SMT painting jet printing bench, wherein the driving power source is connected with the piezoelectric ceramics through a lead; the driving power source controls the piezoelectric ceramics to work through a driving signal; a receiving chamber is arranged between the piezoelectric ceramics and the nozzle; the nozzle is directly connected to the receiving chamber; and the SMT painting jet printing bench is arranged under the nozzle. The receiving chamber is provided with a jet printing material inlet. The SMT painting jet printing bench is 10-30 cm thick. The SMT painting device with CCD computer visual localization is simple in structure, easy to integrate and strong in motility; and with a micro, high-frequency voice-coil linear motor, and a constant-voltage screw propulsion mechanism, the SMT painting device with CCD computer visual localization is convenient to popularize and use.
Description
Technical field
The utility model relates to a kind of being coated with and paints device, more particularly, is that a kind of SMT with CCD computer vision location is coated with and paints device.
Background technology
The principle of digital spraying print machine be according to the documentation that obtains from CAD or CAM with specific word ink spray printing to circuit board, thereby and by uviol lamp, realizes that instant curing completes the process of character technique.Point gum machine is a kind of injection-moulding device commonly used, applies very extensively, needs exactly the position of paster to put in advance a kind of special glue on the PCB plate, fixes surface mount elements, passes through wave-soldering after curing again.The point adhesive curing of surface element has very consequence in the SMT technological process.And in a glue process, environment temperature is very large on the impact of the viscosity of glue and flow velocity, and the too low wire drawing phenomenon that there will be of temperature, and the glue flow velocity is excessively slow will cause the electronic component bottom not to be filled and do not have the effect of protection fully; Excess Temperature can make glue solidify in advance, can't flow and stop up Glue dripping head, and these will directly cause a glue bad, thereby affect production procedure and product quality.
Tin cream thickness in the tin cream spray printing, coarse granule, high temperature constant temperature, spray printing need not adopt industrial digital shower nozzle or micro-control Glue dripping head, necessary research, design specialized injector head.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and is easy to integrated SMT with CCD computer vision location and is coated with and paints device.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of SMT with CCD computer vision location is coated with and paints device, it is characterized in that: mainly by driving power, piezoelectric ceramics, nozzle and SMT, be coated with and paint the spray printing platform and form, driving power connects by wire with piezoelectric ceramics, driving power is by driving the work of signal controlling piezoelectric ceramics, be provided with cavity volume between piezoelectric ceramics and nozzle, nozzle is directly connected on cavity volume, and SMT is coated with and paints the spray printing platform and be located at nozzle below.
Described cavity volume is provided with spray printing materials entrance.
Described SMT is coated with and paints spray printing platform thickness is 10-30cm.
The utlity model has following beneficial effect:
(1) simple in structure, be easy to integratedly, dynamic role is strong;
(2) adopt fine motion, the voice coil motor of high frequency, constant voltage screw propulsion mechanism, easy to use.
Description of drawings
Fig. 1 is overall structure figure of the present utility model.
Wherein, the 1-driving power, the 2-piezoelectric ceramics, the 3-nozzle, the 4-cavity volume, 5-barrier film, 6-spray printing material inlet, 7-SMT are coated with paints the spray printing platform.
The specific embodiment
Embodiment 1:
SMT, the electronic circuit surface installation technique, be called surface mount or surface mounting technique.It is a kind ofly will without pin or short leg surface-assembled components and parts, (be called for short SMC/SMD, Chinese claims the sheet components and parts) be arranged on the surface of the surface of printed circuit board or other substrate, by the methods such as Reflow Soldering or the immersed solder circuit load technology of welding assembly in addition.
As shown in Figure 1, a kind of SMT with CCD computer vision location is coated with and paints device, it is characterized in that: mainly by driving power 1, piezoelectric ceramics 2, nozzle 3 and SMT, be coated with and paint spray printing platform 7 and form, driving power 1 is connected and is connected by wire with piezoelectric ceramics, driving power 1 is by driving 2 work of signal controlling piezoelectric ceramics, be provided with cavity volume 4 between piezoelectric ceramics 2 and nozzle 3, nozzle 3 is directly connected on cavity volume 4, and SMT is coated with and paints spray printing platform 7 and be located at nozzle 3 belows.Piezoelectric ceramics 2, a kind ofly can, with mechanical energy and the electric energy ceramic material of conversion mutually, belong to Inorganic Non-metallic Materials.This is a kind of material with piezo-electric effect.
Further, cavity volume 5 is provided with spray printing materials entrance 6.
Further, to be coated with and to paint spray printing platform 7 thickness be 10-30cm to described SMT.
This SMT with CCD computer vision location is coated with and painted device before actual spray printing, and according to the requirement of the spray printing materials of each pcb board, 4 fill the spray printing materials from spray printing materials entrance 6 toward cavity volume, and should fill full; In actual spray printing process, cavity volume should at every moment keep full occupied state, when the switch of driving power 1 is closed, driving power 1 drives piezoelectric ceramics 2 work, piezoelectric ceramics 2 and according to the signal of driving power 1, act on barrier film 5, the motion of barrier film 5 forces the spray printing materials from nozzle 3 ejection, the spray printing material accurately spray printing to pcb board.When the spray printing material constantly was ejected, the spray printing materials also needed constantly 4 fillings from spray printing materials entrance 6 toward cavity volume, and this just can make in cavity volume 4 state that always remains on full filling spray printing material.The utility model is special-purpose injector head, is enlightened in the publicity of the 3D in forward position printing technique and demonstrates, and, with reference to its material delivering structure, adopts fine motion, the voice coil motor of high frequency, constant voltage screw propulsion mechanism, design tin cream ejection assemblies device, structure.
The above; it is only the utility model patent preferred embodiment; but the protection domain of the utility model patent is not limited to this; anyly be familiar with those skilled in the art in the disclosed scope of the utility model patent; be equal to replacement or changed according to technical scheme and the utility model patent design thereof of the utility model patent, all being belonged to the protection domain of the utility model patent.
