Description
Technical field
The utility model relates to a kind of vacuum screen printer vacuum chambers.
Background technique
During manufacturing pcb board, some pcb boards need to carry out consent, such as the hole LD or plated-through-hole, so as to
Support is formed at foramen primum cavity, plated with copper improves contact pads area and planarization, enhances soldering reliability, in the past, pcb board
After piercing, usually in the way of screen painting, work materials required for resin or other are set on pcb board and are matched
The movement of scraper or scraper to smear back and forth is closed, by each hole location of required work materials filling pcb board, is made on pcb board
Each hole location insert required for after work materials, relevant subsequent production process is carried out, when this mode is in the form of hole location
When different, it because of many influences can lead to not that fast and accurately required material is filled into hole location, moreover, filling perforation
Work materials afterwards are miscellaneous air, dust, and the work materials in hole is easy to cause to have bubble, recess or discontinuous situation hair
It is raw, therefore, vacuum screen printing consent is typically now used, the pcb board of consent will be needed to be put into vacuum chamber, vacuum pump set vacuumizes
Afterwards, it after by the indoor ink discharge device ink-jet of vacuum, opens vacuum chamber and further takes out pcb board, although can quickly and accurately fill out hole
It is full, and heave, be recessed or discontinuous situation is few, but since the space of vacuum chamber is bigger, the pumpdown time is long, work
Make that efficiency is slow, this there is certain shortcoming, and the vacuum pipe of previous vacuum chamber is by vacuum chamber cover board and vacuum
Pump connection, in operation, needs are frequently mobile when vacuum cover board works, and will lead to vacuum pipe damage tired out, cause true
Vacant duct gas leakage.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of structures simply, conveniently vacuumizes and prevent tracheae gas leakage
Vacuum screen printer vacuum chamber.
The technical scheme adopted by the utility model is the utility model includes vacuum chamber body and vacuum chamber cover board, institute
State the top surface that the vacuum chamber body is arranged in vacuum chamber cover board, the vacuum chamber body be internally provided with top vacuum chamber with
Lower vacuum room, the top vacuum chamber interior walls are provided with table top airflow channel, and the table top airflow channel is provided with tracheae and connects
The contact surface of head, the gas-tpe fitting and the top vacuum chamber is provided with sealing ring, and the gas-tpe fitting extension end is provided with
Vacuum pipe.
By above scheme as it can be seen that in the present invention, the airflow channel of the top vacuum chamber on cover board vacuumized changes
Onto the table top of top vacuum chamber, vacuum room cover intralamellar part is provided with an airflow channel, is passing through sealing ring, gas-tpe fitting and true
Vacant duct connection, has reached vacuum pipe and has not needed to move, can also extract room air out, overcome vacuum pipe damage tired out
It is bad, lead to the problem of gas leakage.
Further, the vacuum pipe, the gas-tpe fitting are all connected to inside with the table top airflow channel.
Further, several stiffening plates are provided on the vacuum chamber body outer wall, several described stiffening plate one end
It is connected with the bottom plate of the vacuum chamber body, the top phase of the other end of several stiffening plates and the vacuum chamber body
Connection.
By above scheme as it can be seen that in the present invention, stiffening plate can enhance the anti-pressure ability of vacuum chamber cavity.
Further, the vacuum room cover plate top surface is provided with several buffering stomatas.
By above scheme as it can be seen that in the present invention, when vacuum chamber releases vacuum state, buffering stomata can slow down sky
The flow rate of gas achievees the effect that safe.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional view of the utility model.
Specific embodiment
As shown in Figures 1 and 2, specific embodiment of the present utility model is: the utility model includes 1 He of vacuum chamber body
The top surface of the vacuum chamber body 1, the inside of the vacuum chamber body 1 is arranged in vacuum chamber cover board 2, the vacuum chamber cover board 2
It is provided with top vacuum chamber 3 and lower vacuum room 4,3 inner wall of top vacuum chamber is provided with table top airflow channel 5, and described
Face airflow channel 5 is provided with gas-tpe fitting 6, and the contact surface of the gas-tpe fitting 6 and the top vacuum chamber 3 is provided with sealing ring
7,6 extension end of gas-tpe fitting is provided with vacuum pipe 8.The airflow channel of top vacuum chamber 3 on cover board vacuumized changes
Onto the table top of top vacuum chamber 3, it is provided with an airflow channel inside vacuum chamber cover board 2, is passing through sealing ring 7, gas-tpe fitting 6
And vacuum pipe 8 connects, and has reached vacuum pipe 8 and has not needed to move, can also extract room air out, has overcome vacuum pipe 8
It is tired out to damage, lead to the problem of gas leakage.
In this specific embodiment, in the vacuum pipe 8, the gas-tpe fitting 6 are all connected to the table top airflow channel 5
Portion.Several stiffening plates 9 are provided on 1 outer wall of vacuum chamber body, several described 9 one end of stiffening plate and the vacuum chamber
The bottom plate of ontology 1 is connected, and the other end of several stiffening plates 9 is connected with the top of the vacuum chamber body 1.Reinforce
Plate 9 can enhance the anti-pressure ability of vacuum chamber cavity.
In this specific embodiment, 2 top surface of vacuum chamber cover board is provided with several buffering stomatas 10.When vacuum chamber releases very
When dummy status, buffering stomata 10 can slow down the flow rate of air, achieve the effect that safe.
The utility model is applied to the technical field of vacuum screen printer.
Although the embodiments of the present invention are described with practical solution, does not constitute the utility model is contained
Justice limitation, for those skilled in the art, according to this specification to the modification of its embodiment and with the group of other schemes
Conjunction will be apparent from.
