[0025] Figures 1-3 This is a schematic diagram of a pre-arranged ejector pin device according to an embodiment of the present invention. The pre-arranged ejector pin device is used to pre-arrange multiple first ejector pins 8 that need to be arranged on the substrate 11 inside the PCB printer. The multiple first ejector pins 8 serve as supports for a PCB board. (See reference...) Figure 1 The pre-arranged ejector pin device includes a base plate 1 and a first splicing plate 3. Multiple support columns 2 are provided on the base plate 1, and the first splicing plate 3 is snapped together between these support columns. First ejector pins 8 are placed on the first splicing plate 3. This means that by pre-positioning multiple first ejector pins 8 corresponding to the PCB board after the changeover on the first splicing plate 3, after the actual changeover, the first splicing plate 3 only needs to be placed directly on the printing press substrate 11 to complete the arrangement of the first ejector pins 8 after the changeover. This achieves rapid arrangement of the first ejector pins 8, effectively solving the shortcomings of the prior art and improving the efficiency of ejector pin arrangement on the printing press. The bottom of the first ejector pin 8 has a magnet, and the first splicing plate 3 is made of metal to facilitate the attraction of the magnetized first ejector pin 8, thus ensuring that the first ejector pin 8 will not fall off the base plate 1 during transportation.

[0026] Furthermore, the support column 2 is used to support the PCB board, thereby better arranging the first ejector pin 8 according to the PCB and speeding up the placement time of the first ejector pin 8. It should be noted that the aforementioned PCB board generally refers to the PCB board after the wiring is completed, ensuring that the ejector pins arranged on the pre-arranged ejector pin device correspond to the PCB board after the wiring is completed. To evenly support the PCB board, four support columns 2 are provided and evenly distributed on the base plate 1. Moreover, for convenient installation of the support column 2, both the support column 2 and the base plate 1 are equipped with magnets, so that the support column 2 can be attracted and installed on the base plate 1 by the magnets.

[0027] Then, refer to Figure 5As the first splicing plate 3 on which the top pin is placed, the first splicing plate 3 is movably installed with the first handle 301 on both sides, and the first handle 301 can greatly facilitate the operator to move the first splicing plate 3. In some examples, a plurality of first insertion columns 3011 are formed on the first handle 301, and a plurality of first insertion holes 3012 are correspondingly formed on the first splicing plate 3, and the first insertion columns 3011 are clamped and installed in the first insertion holes 3012 to achieve the movable installation of the first handle 301 on the first splicing plate 3.

[0028] In addition, referring to Figure 4 In order to facilitate the positioning of the first splicing plate 3 when the substrate 11 is installed in the printing machine, and to avoid the placement error of the first splicing plate 3, a positioning column 9 is arranged at the bottom of the first splicing plate 3, which is used to be matched and installed with the positioning hole 10 on the substrate 11. After the positioning column 9 is clamped and installed in the positioning hole 10, the positioning and fixing of the first splicing plate 3 on the substrate 11 is achieved. Since the second splicing plate 4 is connected with the first splicing plate 3, only the position of the first splicing plate 3 needs to be confirmed to be correct, so as to avoid the defect that the position of the top pin is not accurate. In addition, in order to cooperate with the arrangement of the positioning column 9, a pre-positioning hole is also arranged on the bottom plate 1, and the size of the pre-positioning hole is the same as that of the positioning hole. When the first splicing plate is clamped and installed on the bottom plate 1, the positioning column 9 is matched and installed with the pre-positioning hole, so that the first splicing plate is stably clamped and installed on the bottom plate 1, so as to avoid the influence on the positioning column 9.

[0029] Next, referring to Figure 2In order to apply the pre-arranged pin device to a larger area PCB, the pre-arranged pin device is also used to pre-arrange a plurality of second pins 12, which have the same function as the first pins 8 and are also used for communication connection with the PCB. The pre-arranged pin device further comprises a second splicing plate 4 on which the second pins 12 are placed and which is disposed on the bottom plate 1, and the second splicing plate 4 is clamped and installed on the first splicing plate 3 through the first connecting assembly 5. Specifically, the first connecting assembly 5 comprises a first connecting block 501 and a second connecting block 502, the first connecting block 501 is installed on the first splicing plate 3 and has a first clamping groove 5011 on one side, the second connecting block 502 is installed on the second splicing plate 4 and has a first clamping column 5021 on one side, and the first connecting block 501 and the second connecting block 502 are clamped and installed through the first clamping column 5021 and the first clamping groove 5011 to connect the first splicing plate 3 and the second splicing plate 4 on the bottom plate.
