Description
Technical field
The utility model relates to screen printer net frame lifting structure more particularly to a kind of screen printer steel mesh screw rod synchrodrives
Structure.
Background technique
Screen printer is that solder(ing) paste or Heraeus by silk screen are bitten setting on printed circuit board (PCB) pad by one kind
It is standby.Using unilateral driving, opposite side is aided with support leads the steel mesh lifting module of commercially available most common solder(ing) paste screen printer
To structure, such as straight-line guide rail slide block；When work, power side drives steel mesh lifting to realize the target actions such as tin scraping and off-grid, takes off
When net, drive side and opposite side due to can not stringent synchronization, steel mesh is integrally oblique, cannot achieve strict vertical off-grid, takes off
Tin cream is easy to fall off when net, and printing effect and precision are not satisfactory.
Therefore, the prior art is defective, needs to improve.
Utility model content
The technical problems to be solved in the utility model is：A kind of silk-screen steel mesh synchronous driving mechanism for screws is provided, steel is avoided
When net off-grid, steel mesh obliquely caused by tin cream peels off, printing effect is bad and the product defects such as low precision.
The technical solution of the utility model is as follows：The utility model provides a kind of screen printer steel mesh screw rod synchrodrive
Structure, including：Several ball screws being installed in rack, the ball nut and a motor covered on the ball screw, institute
It states ball screw bottom and synchronizing wheel is installed, pass through synchronous band connection between the synchronizing wheel, rotated synchronously with realizing；The rolling
Elevator is installed, the elevator is for installing steel mesh substrate on pearl nut；The motor passes through shaft coupling and any rolling
Connection at the top of ballscrew.The motor rotation drives whole ball-screws to rotate synchronously, to realize ball nut and installation
Elevator synchronization lifting on ball nut, the steel mesh substrate realize vertical lift.
Further, the motor is servo motor.The servo motor has high-precision, stable, responds fast
The features such as speed, low noise.
Further, the ball screw is fixed in rack by two screw rod supporting blocks, and the ball nut is located at two
Between screw rod supporting block.
Further, the motor is installed in rack by a motor cabinet.
Further, the quantity of the ball screw is four, the pairs of horn shape setting of four ball screws, convenient for placing steel
Net substrate.
Further, the quantity of the synchronizing wheel is four.
Further, each synchronizing wheel is installed on the tensioning shaft assembly in rack equipped with one, it is ensured that synchronous belt is drawn
Tightly, realize that four ball screws are synchronous.
Using the above scheme, the utility model provides a kind of screen printer steel mesh synchronous driving mechanism for screws, passes through motor
Rotation drives the rotation of the synchronizing wheel of ball screw and its bottom, is rotated synchronously by other three synchronizing wheels of synchronous band connection, four
The synchronization lifting for being converted to four groups of ball nuts and its elevator above of group ball screw, is mounted on elevator
On steel mesh substrate realize vertical lift, tin cream peels off when effectively avoiding steel mesh off-grid, guarantees the printing effect and precision of tin cream.
