Description

Technical Field

[0001] The invention relates to a screen printing machine capable of rotating reversing and adjusting UVW of a printing table, belonging to the technical field of screen printing machines. Background Art

[0002] In the prior art, screen printing mainly adopts the following two methods: one is to transmit by standard transmission to a turntable structure driven by a DD motor, and transfer it to the printing station by rotating the turntable at a certain angle; the other is to transmit by standard transmission to a linear motor cross printing platform, and drive the printing platform to the printing station by the linear motor.

[0003] None of the above methods have the functions of rotation reversing and printing table UVW adjustment. The printing head can only be adjusted through camera vision, which leads to limitations in rotation angle and position, poor compatibility with silicon wafers of different sizes and whole wafers and half wafers, and frequent paper roll replacement is easily affected by dirt. Summary of the invention

[0004] The present invention proposes a screen printing machine with rotatable reversing and UVW adjustment of the printing table, which aims to overcome the above-mentioned shortcomings of the prior art, meet the compatibility of printing whole wafers and half wafers, reduce the feeding angle of silicon wafers, improve the accuracy of silicon wafer placement, reduce the frequency of paper roll replacement, simplify maintenance, and improve work efficiency.

During operation, the film-feeding telescopic conveyor mechanism transfers the cells transferred by the film-feeding and transporting mechanism group to the first and second transmission printing tables respectively, and the transfer mechanism moves the 1st and 3rd transmission printing tables to the corresponding positions of the 1st and 2nd printing head mechanisms. At the same time, the unprinted 2nd and 4th transmission printing tables are transferred and reversed during the process of splicing. The 1st and 3rd transmission printing tables that have been printed reverse and rotate in the process of returning to the original transmission station, and then transfer the cells to the film-feeding telescopic conveyor mechanism, and output them to the film-feeding and transporting mechanism group, completing the film-feeding and splicing work. At the same time, the 2nd and 4th transmission printing tables are transferred to the corresponding printing stations for printing, and the whole action is repeated in this way to realize the rotation reversal and transmission of the cell after printing.

[0006] Preferably, the transmission printing table comprises two half-piece structures, one side of the transmission printing table is fixedly connected to the rotary reversing mechanism, and the other side of the transmission printing table is connected to the rotary reversing mechanism via a UVW adjustment platform.

[0007] Alternatively, preferably, the transmission printing table comprises two half-piece structures, and the transmission printing tables on both sides are connected to the rotation reversing mechanism through a UVW adjustment platform respectively.

[0008] Preferably, the transmission printing table is a dual-motor structure, including a printing table, a motor, and a printing table paper reel. A pair of motors are provided under the printing table. The output ends of the two motors are respectively connected to a printing table paper reel through a transmission member. The two printing table paper reels are arranged in parallel under the printing table near the two ends.

[0009] Alternatively, preferably, the transmission printing table is a single-motor structure, including a printing table, a motor, a printing table paper reel shaft, a passive shaft and a tensioning mechanism, a motor is arranged at one end below the printing table, the motor is connected to a printing table paper reel shaft through a transmission member, the printing table paper reel shaft is located at one end of the printing table, a passive shaft is arranged parallel to the printing table paper reel shaft at the other end of the printing table, and a tensioning mechanism is arranged between the printing table paper reel shaft and the passive shaft.

[0010] The advantages of the present invention are as follows: the structural design is simple and reasonable, the direction can be rotated and reversed during the telescopic transmission and transplanting process, and a UVW adjustment platform is preferably provided. The UVW adjustment platform is combined with a rotating direction-reversing mechanism and then connected to a transplanting mechanism, which can well solve the compatibility problem of printing a whole sheet and a half sheet, and the problem that the printing platform is easily affected by dirt due to frequent paper roll replacement. The maintenance is convenient, the work efficiency is high, time and labor are saved, and production costs can be saved. BRIEF DESCRIPTION OF THE DRAWINGS
