According to the size and thickness of the narrow strip glass to be printed, the position of X-direction positioning clamping device 4 and the lifting height controlled by air cylinder 5 are set through control system. The pressure of air cylinder 5 is adjusted through control system, makes X-direction positioning wheel 6 contact glass surface gently, further adjusts the position of glass, ensures its accurate alignment with silk screen plate. After everything is ready, start silk screen machine, begin printing process. During the period, the equipment will automatically adjust and maintain the position of glass, ensure the continuity and consistency of printing. After printing task is completed, close silk screen machine, loosen X-direction positioning clamping device 4, take down the printed glass, carry out subsequent processing.

[0026] The precise positioning of the narrow strip of glass during the silk-screen printing process is achieved by the cooperation of the X-direction positioning clamping device 4 and the X-direction positioning wheels 6. This ensures the accurate transfer of the silk-screen printed pattern, thereby improving the printing quality. The provision of the guide rail assembly 3 ensures the smooth movement of the transmission assembly 2 along the X-axis direction, thereby reducing printing errors caused by vibration or deviation and improving the stability of the overall operation.

[0027] Preferably, the X-direction positioning wheels 6 are provided with five wheels, four of which are arranged in a straight line, and the fifth wheel is arranged behind the middle part of the straight line. This arrangement can further stabilize the position of the glass, especially during the printing process of a long narrow strip of glass. The fifth positioning wheel is arranged behind the middle part, which helps to balance the front and back forces, reduces the displacement caused by the operation of the machine or the weight of the material, and enables the positioning device to more accurately control the positioning and parallelism of the glass, thereby ensuring the alignment and consistency of the printed pattern.

The cooperation of the clamping device guide rail 24 and the movable connecting piece 25 enables the X-direction positioning clamping device 4 to move linearly along the clamping device guide rail 24, facilitating the position adjustment of the X-direction positioning clamping device 4.

[0033] In summary, in use, first connect the control system to ensure that all electrical connections are correct and perform preliminary function tests to confirm the operation of the servo motor, the air cylinder 5 and other electric components. According to the size of the narrow strip glass to be printed, adjust the position of the X-direction positioning clamping device 4 and set the lifting height controlled by the air cylinder 5 to ensure that the X-direction positioning wheel 6 can adapt to different thicknesses of glass. Adjust the first positioning device adjusting assembly 35 and the second positioning device adjusting assembly 13 to adapt to the width and length of the glass to ensure the stability of the glass during printing. Place the narrow strip glass on the base 1 and use the X-direction positioning clamping device 4 and the positioning wheel to accurately position the glass.
