[0045] The working principle and process of this utility model are as follows: During use, the printing content is entered into the inkjet printer 140. Based on the position on the PCB board where an ET stamp or other information needs to be entered, the first guide rod 166 is moved to control the position between the irregular plate 167 and the edge of the bracket 110. After adjustment, the first guide rod 166 is held, and the second locking member 165 is rotated. The lower end of the second locking member 165 presses against the outer wall of the first guide rod 166, fixing the first guide rod 166 onto the vertical plate 164. Similarly, the first connecting plate 172 and the second connecting plate 174 are rotated to adjust the position of the inkjet gun 150. After adjustment, the first connecting plate 172 is held, and the third locking member 173 is rotated. The end of the third locking member 173 presses against the outer wall of the first guide rod 166. The outer wall of the column 171 is used to fix the first connecting plate 172 onto the column 171. The second connecting plate 174 is held in place, and the nut sleeve 179 is rotated. The lower surface of the nut sleeve 179 presses against the upper surface of the second connecting plate 174, fixing the second connecting plate 174 onto the first connecting plate 172. Then, the block 175 is pulled to adjust its position on the third guide rod 176. After adjustment, the block 175 is held in place, and the fourth locking member 177 is rotated. The end of the fourth locking member 177 presses against the outer wall of the third guide rod 176, fixing the block 175 onto the third guide rod 176. The PCB board product tested inside the flying probe tester is manually removed. The operator presses down on the baffle 168 with one hand, so that the lower surface of the baffle 168 contacts the... With the transmission belt 120 in place, one hand aligns a corner of the PCB board with the angle formed by the baffle 168 and the irregular plate 167. Then, the baffle 168 and the PCB board are released. Under the reaction force of the spring 1690, the baffle 168 moves back to its initial position. The manual operation of the control box 130 activates the transmission belt 120, conveying the PCB board to the designated area. When the power-off sensor 180 detects the presence of the PCB board, it transmits a signal to the control box 130. The control box 130 then controls the inkjet printer 140 and the inkjet gun 150 to operate. The inkjet gun 150 automatically prints the ink. After printing, the transmission belt 120 delivers the PCB board to the unloading table 1916. After a specified time, the motor 1914 starts operating. The rotation of the output shaft drives the gear transmission component 1913 to rotate. Under the combined action of the gear transmission component 1913, the lead screw 1911, and the fourth guide rod 1915, the unloading table 1916 moves up and down, thus lowering the unloading table 1916 to a specified height for automatic material receiving. This automatic ET stamping machine has no restrictions on the content and font of the inkjet print; it eliminates quality defects such as ink bleeding and positional changes caused by manual stamping; efficiency can be greatly improved; it can automatically unload the printed PCB boards, and the unloading table 1916 can move down according to the number of PCB boards; the positioning mechanism 160 and the transmission belt 120 can move the PCB boards to a designated area; the position of the inkjet gun 150 can be flexibly adjusted according to the size of the product.

[0046] The embodiments of this utility model have been described in detail above, but the content is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
