Specific implementation mode
In order to facilitate the understanding of those skilled in the art, below in conjunction with attached drawing and embodiment to the utility model into traveling
One step is described in detail.
Embodiment one
As shown in Figure 1, a kind of block-like pressure head structure improving welding quality is present embodiments provided, below pressure head structure
It has been sequentially placed mask plate and mask plate framework.The pressure head structure include multiple electromagnet constitute pressure head, the first control module,
Second control module and third control module.The present embodiment use word order 3 electromagnet, respectively the first electromagnet,
Second electromagnet and third electromagnet, wherein the first control module is connect with these three electromagnet simultaneously, first control is located at center
The second electromagnet be powered, then first electromagnet and second electromagnet energization of the control positioned at both sides.Since electromagnet is powered
After generate magnetic field, after being placed on the magnetic force that mask plate below pressure head structure is first acted on from middle part upwards, twice again by
The magnetic force acted on upwards, by making mask plate different parts by magneticaction, to influence under tension and what is deformed cover
Diaphragm plate flattens and the mask plate after flattening is adsorbed onto on pressure head.When pressure head structure adsorbs that mask plate continues to move downward will
When contacting mask plate framework, the second control module controls the first control module, disconnects the electricity of all electromagnet, and magnetism disappears, according to
Mask plate is pressed on mask plate framework by the gravity of pressure head and is welded；When the welding is completed, third control module
It controls the first control module and the second control module is stopped, control entire pressure head and move upwards, leave soldered cover
Diaphragm plate continues the welding job of next mask plate.
In the present embodiment, the first control module includes first sensor, second sensor and 3rd sensor；First passes
Sensor is connect with the first electromagnet, controls the first magnet switching electricity；Second sensor is connect with the second electromagnet, control
Second magnet switching electricity；3rd sensor is connect with third electromagnet, control third magnet switching electricity.Second control module
Including the 4th sensor；4th sensor is connect with first sensor, second sensor and 3rd sensor simultaneously, is controlled simultaneously
First sensor, second sensor and 3rd sensor work.Third control module includes the 5th sensor；5th sensor is same
When connect with first sensor, second sensor, 3rd sensor and the 4th sensor, while controlling first sensor, second
Sensor, 3rd sensor and the 4th working sensor.
Wherein, the sensor in order to control ram movement distance and electromagnet power supply break-make range sensor, Ke Yiwei
Optical distance sensor, infrared distance sensor and ultrasonic distance sensor.It is passed using infrared distance in the present embodiment
Sensor incudes the distance between pressure head and mask plate, to control the energization shape of different electromagnet by infrared distance sensor
State obtains suitable magnetic field, and the accurate fine mask plate deformed because stress stretches is flattened.When pressure head exists attaching mask
When on mask plate framework, the 4th sensor controls first sensor, second sensor and 3rd sensor work, by all electricity
Magnet powers off, and magnetism disappears, and merely with the gravity of pressure head, the accurate fine mask plate of flattening is fitted in mask plate framework
On, complete welding；When welding completion, the 5th sensor controls remaining four sensor simultaneously, and electromagnet is made still to disconnect
Power supply lifts pressure head, since all electromagnet during lifting pressure head are maintained at off-position, do not generate magnetic force thus not
Mask plate after the mask plate of continuation tensioning or welding can be impacted.

Iron, third electromagnet, the 4th electromagnet and the 5th electromagnet；Sensor is respectively first sensor, second sensor, third biography
Sensor, the 4th sensor and the 5th sensor；Wherein first sensor is connect with the first electromagnet and the 5th electromagnet simultaneously, is controlled
Make the power on/off of the first electromagnet and the 5th electromagnet；Second sensor is connect with the second electromagnet and the 4th electromagnet simultaneously,
Control the power on/off of the second electromagnet and the 4th electromagnet；3rd sensor is connect with third electromagnet, controls third electromagnet
Power on/off；4th sensor is connect with first sensor, second sensor and 3rd sensor simultaneously, controls all electromagnet
After power-off is stopped, entire pressure head is made to push；5th sensor is connect with remaining four sensor simultaneously, controls all electromagnetism
After iron power-off is stopped, entire pressure head is made above to carry.5 electromagnet of the present embodiment may make the magnetic force stress of mask plate more equal
It is even, further increase the flatness of mask plate.
The specific work step of pressure head structure of the present embodiment is as follows：
1,3rd sensor controls centrally located third electromagnet and is powered, and third electromagnet generates magnetic field after being powered, right
It places the intermediate of the mask plate below push-down head and generates upward active force；
2, when pressure head continues to move downward, second sensor control is positioned at the second electromagnet of third electromagnet both sides and the
Four electromagnet are powered, and generate magnetic field, mask plate is by the position of clip tensioning by upward active force；
3, when pressure head touches mask plate, first sensor controls outermost first electromagnet and the 5th electromagnetism Tie Tong
Electricity, entire pressure head generate magnetic field, are adsorbed on pressure head by the pressuring diaphragm of clip tensioning, it is made entirely to flatten；
4, pressure head adsorbs pressuring diaphragm and continues to move down, and when mask plate touches mask plate framework, the 4th sensor starts
Work, control first sensor, second sensor and 3rd sensor make all magnet power off, and magnetic force disappears, and only leans on pressure head
Mask plate is pressed on mask plate framework and is welded by gravity；
5, when mask plate welding after the completion of, the 5th sensor start to work, control remaining four sensor make it is all
Electromagnet all powers off, and controls pressure head and move upwards, and leaves the mask plate that welding is completed, and continues next mask to be welded
The welding job of plate.Since during pressure head leaves mask plate, electromagnet has powered off, without magnetic force, so the pressure left
Head will not generate soldered mask plate the effect of power, to cause new ripple, it is ensured that entirely welded
The flatness of mask plate in journey.
