Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
Refering to Fig. 1, for the structural representation for being applied to the coating liquid supplying device that flexible base board makes of the embodiment of the present invention
Figure, coating liquid supplying device mainly include shell 10, the coating fluid storage container 20 in shell 10 and connect with shell 20
Logical vacuum generating device 30 offers coating fluid import 11, coating fluid outlet 12 on shell 10, and coating fluid storage container 20 is same
When 12 connect with coating fluid import 11, coating fluid outlet, and closed cavity 100 surrounded with shell 10；Vacuum generating device 30
It connects with cavity 100, is exported coating fluid from coating fluid with 20 volume of coating fluid storage container being made to become smaller the pressurization of cavity 100
12 extrude.
As one of which embodiment, at least a portion of coating fluid storage container 20 is made of flexible material, also may be used
To be all made of flexible material, such as material of the Teflon class with certain flexibility and intensity may be employed, in external force
Under the action of, which can generate a degree of deformation without breakage, while have certain deformation recovery capability again.
When supplying coating fluid, vacuum generating device 30 inflates cavity 100 and compresses coating fluid storage container 20, so that coating fluid
Coating fluid in storage container 20 is squeezed out with the deformation of coating fluid storage container 20 from coating fluid outlet 12, in this process
In, by vacuum generating device 30 to 100 persistent pressure of cavity until coating fluid storage container 20 is completely shrivelled, so as to fulfill painting
Then the supply of cloth liquid, makes coating fluid storage container 20 restore to the original state the pumping of cavity 100, leads to by vacuum generating device 30
Crossing coating fluid import 11 makes coating fluid storage container 20 repeat above operation and next coating fluid confession can be realized full of coating fluid
To process.
The main part 21 of coating fluid storage container 20 including cryptomere and it is respectively communicated with the of 21 different parts of main part
One pipeline 22 and second pipe 23, first pipe 22, second pipe 23 connect respectively with coating fluid import 11, coating fluid outlet 12
It is logical.First pipe 22, the radial dimension of second pipe 23 are respectively less than the center section of main part 21 so that coating fluid outlet 12
It is easily formed and sprays pressure, ensure the continuous supply of coating fluid.
Preferably, main part 21 includes the two necking parts connected respectively with first pipe 22, second pipe 23, and
Closer to the first pipe 22 or second pipe 23 closed on, the sectional area of corresponding necking part is smaller.I.e. each necking part
Be bell shape, the section of inner wall vertically is inclined-plane or cambered surface, can allow cryptomere main part 21 very
It is full of well, the injection process of coating fluid autonomous agent part 21 towards second pipe 23 is more smooth.Here, to connect vacuum
Device 30, is further opened with air intlet 13, air outlet slit 14 on shell 20, air intlet 13, air outlet slit 14 respectively with vacuum
Generating means 30 connects.The inlet and outlet of air separates, and can so adjust the air mass flow of inlet and outlet respectively, compare
It inflates or is evacuated using same inlet and outlet, the present embodiment, air inlet and outlet can be carried out at the same time, practical operation
Only need reasonably to control the draught head of air intlet 13 and air outlet slit 14 in journey, you can easily adjust in cavity 100
Pressure, inflation, pumping switching action it is sensitiveer.
Further, coating fluid import 11, coating fluid export 12 two opposite ends for being respectively arranged on shell 10, first pipe 22
The both ends of main part 21 are respectively arranged on second pipe 23, air intlet 13, air outlet slit 14 are respectively arranged on the same of shell 10
One side wall.Coating fluid storage container 20 can be designed as relatively regular elongated shape, air intlet 13, air outlet slit 14
Be respectively arranged in the long side wall of shell 10, the long side wall face with coating fluid storage container 20, can easily be inflated and
Compressed action.
With reference to shown in Fig. 2, it is additionally provided with to prevent between the coating fluid import 11 of the present embodiment and coating fluid storage container 20
The non-return module 110 that only coating fluid in coating fluid storage container 20 flows back under pressure towards coating fluid import 11.As
One of which embodiment, non-return module 110 include block 111 and baffle 112, and baffle 112 is from coating fluid storage container 20
Wall extends, and blocking 111 is movably disposed in coating fluid flow direction between baffle 112 and coating fluid import 11, and blocks 111
Diameter be more than coating fluid import 11.Baffle 112 is obliquely installed compared with coating fluid flow direction, i.e., is preferably flowed to along coating fluid
It obliquely extends from, to reduce the influence to coating fluid flowing, coating fluid import 11 and the junction of coating fluid storage container 20
Using inclined connection wall 11a connections, i.e., from coating fluid import 11 towards coating fluid storage container 20, what connection wall 11a was formed opens
Mouthful become larger, can preferably with 111 cooperations of blocking, can also play to block 111 guiding function.In addition, baffle 112 is also
The construction of hollow out is designed as, offers the through hole 1120 passed through for coating fluid thereon, can be reduced to greatest extent for coating
The resistance of liquid, at the same can guarantee again for block 111 position-limiting action.
When from coating fluid import 11 inject coating fluid when, block 111 under the thrust of coating fluid along the flow direction of coating fluid
It moves, is finished when coating fluid injects, using vacuum generating device 30 to cavity 100 between coating fluid import 11 and baffle 112
During pressurization, coating fluid is squeezed out by coating fluid outlet 12, meanwhile, a part of coating fluid is also to 111 generations of blocking towards coating fluid
The thrust of import 11, when coating fluid import 11 is moved along connection wall 11a and after be blocked in coating fluid import 11, coating fluid i.e. can not
It is flowed out from coating fluid import 11, realizes the function of preventing that coating fluid from flowing back.
In conclusion the coating liquid supplying device of the present invention is simple in structure, coating fluid is not contacted directly with gas compression chamber,
Without carrying out high-precision processing or grinding to airtight cavity, manufacture is at low cost, will not generate Particle, and coating fluid spues
Flow is big, can be adapted for the making of the substrate of advanced lines.Moreover, the present invention specially devises the knot for preventing that coating fluid from flowing back
Structure so that the supply process of coating fluid is very reliable, coating fluid will not be caused to reveal.
The above is only the specific embodiment of the application, it is noted that for the ordinary skill people of the art
For member, on the premise of the application principle is not departed from, several improvements and modifications can also be made, these improvements and modifications also should
It is considered as the protection domain of the application.
