A fixing screw 109 is mounted on the top surface of the markers 111. The top of the fixing screw 109 passes through the fixing bracket 106 and the lifting plate 102 and extends to the top of the lifting plate 102. Above, a fastening nut 110 is threaded onto the surface of the fixing screw 109. The surface of the fastening nut 110 contacts the inner wall of the lifting plate 102. The bottom end of the marking piece 111 extends into the interior of the fixing frame 106. A circuit board body 114 is placed on the surface of the processing table 112. An L-shaped support plate 113 is provided on the surface of the top position of the processing table 112. The L-shaped support plates 113 are located at the corner positions of the circuit board body 114. Bolts 116 are threaded onto the surface of the L-shaped support plates 113. One end of the bolt 116 passes through the L-shaped support plate 113 and is threadedly fastened to the surface of the processing table 112.

[0022] Furthermore, such as Figure 2 and Figure 4As shown, the surfaces of the processing table 112 and the circuit board body 114 are provided with auxiliary support mechanisms 3. The auxiliary support mechanism 3 consists of a support base plate 31, a support block 32, a fixing pad 33, and a positioning block 34. The support base plate 31 is installed on the surface at the top position of the processing table 112. The surface at the top position of the support base plate 31 is equipped with positioning blocks 34 for auxiliary support of the circuit board body 114. The surface of the positioning blocks 34 is equipped with support blocks 32. The surface of the support blocks 32 is in contact with the surface at the bottom position of the circuit board body 114. The surface of the support blocks 32 is equipped with fixing pads 33. The surface of the fixing pads 33 is in contact with the surface at the bottom position of the circuit board body 114.

[0023] In practice, when the circuit board body 114 is placed above the processing table 112, the bottom of the circuit board body 114 is provided with auxiliary support under the action of the support base plate 31. At this time, the support base plate 31 drives the positioning block 34 to move to the surface of the circuit board body 114. Under the action of the positioning block 34, the position of the circuit board body 114 is positioned. The bottom of the circuit board body 114 moves to contact the surface of the support block 32 and the fixing pad 33. Under the joint action of the support block 32 and the fixing pad 33, the circuit board body 114 is provided with auxiliary support, so as to realize the function of the marking device providing auxiliary support for the circuit board body 114.

[0024] Furthermore, such as Figure 3 and Figure 5 As shown, the processing table 112 and the L-shaped support plate 113 are provided with a universal marking mechanism 2. The universal marking mechanism 2 consists of a positioning plate 21, a stud body 22, an adjustment groove 23 and an adjustment block 24. The positioning plate 21 is installed on the inner wall of the L-shaped support plate 113. The surface of the positioning plate 21 is in contact with the surface of the circuit board body 114. An adjustment block 24 is installed on the surface at the bottom of the L-shaped support plate 113. The surface of the processing table 112 is provided with adjustment grooves 23. The surfaces of the adjustment grooves 23 and the adjustment blocks 24 slide against each other. The surface of the adjustment block 24 is threadedly connected to the stud body 22. One end of the stud body 22 passes through the adjustment block 24 and is threadedly fastened to the inner wall of the adjustment groove 23.

[0025] During implementation, the stud body 22 on the surface of the adjusting block 24 is loosened, and the user pulls the L-shaped support plate 113, causing the L-shaped support plate 113 to drive the adjusting block 24 to slide inside the adjusting groove 23. Under the combined action of the adjusting groove 23 and the adjusting block 24, the L-shaped support plate 113 is guided, so that the distance between the L-shaped support plates 113 can meet the needs of marking the surface of the circuit board body 114. After the adjustment is completed, the user tightens the stud body 22 on the surface of the adjusting block 24, and then tightens the bolts 116 on the surface of the L-shaped support plate 113 to fix the position of the L-shaped support plate 113. The circuit board body 114 moves to contact the surface of the positioning plate 21. Under the action of the positioning plate 21, the corners of the circuit board body 114 are positioned to realize the function of marking circuit board bodies 114 of different sizes.

[0026] Working principle: In use, first place the device base 1 in the designated position, then place the circuit board body 114 to be marked on the surface of the processing table 112, so that the circuit board body 114 is positioned between adjacent L-shaped support plates 113. The user adjusts the position between the L-shaped support plates 113 according to the size of the circuit board body 114. The user loosens the bolts 116 on the surface of the L-shaped support plate 113, and then loosens the stud body 22 on the surface of the adjusting block 24. The user pulls the L-shaped support plate 113, causing the L-shaped support plate 113 to drive the adjusting block 24 to slide inside the adjusting groove 23. Under the combined action of the adjusting groove 23 and the adjusting block 24, the L-shaped support plate 113 is guided, so that the L-shaped support plate 113... The distance between the support plates 113 is sufficient to meet the needs of marking the surface of the circuit board body 114. After adjustment, the user tightens the stud body 22 on the surface of the adjustment block 24, and then tightens the bolts 116 on the surface of the L-shaped support plate 113 to fix the position of the L-shaped support plate 113. The circuit board body 114 moves to contact the surface of the positioning plate 21. Under the action of the positioning plate 21, the corners of the circuit board body 114 are positioned to realize the function of marking the circuit board body 114 of different sizes. This allows the marking device to avoid displacement of the circuit board body 114 during marking, which would result in inaccurate marking. This makes the marking device more widely applicable and more practical.

[0027] Subsequently, when the circuit board body 114 is placed above the processing table 112, the bottom of the circuit board body 114 is provided with auxiliary support under the action of the support base plate 31. At this time, the support base plate 31 drives the positioning block 34 to move to the surface of the circuit board body 114. Under the action of the positioning block 34, the position of the circuit board body 114 is positioned. The bottom of the circuit board body 114 moves to contact the surface of the support block 32 and the fixing pad 33. Under the joint action of the support block 32 and the fixing pad 33, the circuit board body 114 is provided with auxiliary support, so as to realize the function of the marking device providing auxiliary support for the circuit board body 114. This ensures that the marking effect on the surface of the circuit board body 114 is better and more accurate when the marking device is used.

[0028] After the circuit board body 114 is placed, the user simultaneously presses the controller 101 on the surface of the device base 1, causing the controller 101 to control the solenoid valve 117 to open. The simultaneous pressing design prevents the user from having a free hand to operate the circuit board body 114, avoiding accidental hand injury. Compressed gas enters through the air pipe 108, passes through the solenoid valve 117 to one end of the electric push rod 104, and pushes the piston inside the electric push rod 104 downwards. When the piston inside the electric push rod 104 reaches the bottom, the gas is discharged through the solenoid valve 117 from the exhaust port on the surface. The electric push rod 104 drives the lifting plate 102 to move downwards on the surface of the guide rod 105. Under the action of the guide rod 105, the lifting plate 102 is guided. With the threaded engagement of the fixing screw 109 and the fastening nut 110, the marking pieces 111 are respectively installed inside the fixing frame 106. When the lifting plate 102 moves downwards, the lifting... The plate 102 drives the fixing frame 106 to move downward. At this time, the bottom end of the marking piece 111 moves downward to contact the surface of the circuit board body 114. Under the action of the marking piece 111, the surface of the circuit board body 114 is marked. The number of marking pieces 111 is the same as the number of positions to be marked on the surface of the circuit board body 114. This allows different positions on the surface of the circuit board body 114 to be marked simultaneously. The controller 101 realizes the timing function through the connection with the solenoid valve 117 and the electric push rod 104. Through reasonable circuit design and programming, the controller 101 can be used to start or stop the action of the electric push rod 104 at timed intervals. After the electric push rod 104 marks the surface of the circuit board body 114, it can automatically drive the lifting plate 102 to move upward and reset. The user can then remove the circuit board body 114 from the surface of the processing table 112, thus completing the use of the marking device.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
