Problems solved by technology

[0003] When making a double-sided PCB board, it is necessary to print on both sides of the PCB board. When printing on one side of the PCB board and then printing the other side, it is necessary to use the thimble on the dial to contact the blank area on the PCB board to support the PCB board. Oil brushing printing, the dials used by silk screen printing machines on the market are designed independently for each type of PCB board. When switching different types of PCB boards for printing, it is necessary to replace the corresponding dials, which will be very difficult. It is a waste of time and inconvenient, seriously affecting production efficiency, and each type of PCB board needs to be independently designed with a dial, which not only takes up a lot of space for storage, but also causes waste of materials

Embodiment 1

[0036] Figure 1 to Figure 4 The structure of a universal dial for a screen printing machine according to an embodiment of the present invention is schematically shown.

[0037] refer to Figure 1 to Figure 4 , a universal dial for screen printing machine, including thimble 1, pallet 2, lifting device and control device. In addition, the universal dial used for the screen printing machine may also include a base plate 4 and a chassis 5 .

[0038] refer to figure 1 and figure 2 , the number of thimbles 1 is multiple, and the multiple thimbles 1 are distributed in an array.

[0039] refer to figure 1 and figure 2 , a plurality of through holes 21 are formed on the support plate 2, the through holes 21 can be passed through by the thimble 1, the top of the thimble 1 can be tapered, and the thimble 1 with a tapered top can not only make the thimble 1 pass through the through holes smoothly 21, and can effectively reduce the false loss of the thimble 1 to the circuit on th...

Embodiment 2

[0050] Figure 5 to Figure 10 The structure of a universal dial for a screen printing machine according to another embodiment of the present invention is schematically shown.

[0051] refer to Figure 5 to Figure 10 , a universal dial for screen printing machine, including thimble 1, pallet 2, lifting device and control device. In addition, the universal dial used for the screen printing machine may also include a base plate 4 , a chassis 5 and a bracket 7 .

[0052] In this embodiment, the structures of the support plate 2 , the control device, and the chassis 5 are the same as those in the first embodiment, and will not be repeated here.

[0053] refer to Figure 8 and Figure 9 , the thimble 1 is divided into upper and lower sections. The cross section of the thimble 1 near the top of the thimble 1 is polygonal, such as a regular hexagon. The lower section of the thimble 1 is formed with an external thread 11. The top of the thimble 1 is tapered. The bottom is formed w...

Abstract

The invention discloses a universal dial for a screen printing machine. The universal dial comprises a plurality of ejector pins, a supporting plate, a lifting device and a control device. According to the universal dial and the control device, automatic layout of the ejector pins on the supporting plate can be achieved according to a PCB layout design drawing stored in a screen printing machine, when a second face of a PCB is printed, contact between uncured ink on the first face and a table face of the screen printing machine is avoided, damage of the ejector pins to a circuit can be effectively avoided, and the production efficiency of the PCB is improved. Compared with the prior art, the automatic silk-screen printing device has the advantages that needle dials do not need to be independently designed for PCBs of different models, cost is reduced, when the PCBs of different models are switched for printing, the corresponding needle dials do not need to be replaced, only the ejector pins distributed in the array mode need to be controlled to ascend or descend, time is saved, production efficiency is greatly improved, and automation of silk-screen printing is achieved.

Description

technical field [0001] The present invention relates to a universal dial for a screen printing machine. Background technique [0002] In the production process of the PCB circuit board, it is necessary to use a screen printing machine to perform double-sided solder resist or character printing operations on the surface of the PCB circuit board. [0003] When making a double-sided PCB board, it is necessary to print on both sides of the PCB board. When printing one side of the PCB board and then printing the other side, it is necessary to use the thimble on the needle plate to contact the blank area on the PCB board to support the PCB board. For oil printing, the needle discs used by screen printing machines on the market now design a needle plate independently for each type of PCB board. When switching between different types of PCB boards for printing, the corresponding needle plate needs to be replaced, which will be very It is time-wasting and inconvenient, which serious...
