DETAILED DESCRIPTION
[0018] The utility model is specifically described below in combination with the drawings.
[0019] A PCB substrate printing table capable of quickly changing stencil, as shown in Figure 1 and Figure 2 , comprises an organic table 1, an electric mounting rack 2 is connected to the upper side of the rear part of the table 1, connecting arms 3 are connected to the left and right sides of the electric mounting rack 2, four reserved holes 31 are opened on the connecting arms 3, three connecting plates 4 are connected to the connecting arms 3, triangular rib plates for reinforcement are connected to the connecting plates 4, first magnetic suction blocks 5 are connected to the lower parts of the connecting plates 4, mounting plates 8 are connected to the inner sides of the connecting arms 3, the mounting plates 8 are detachable connection structures, screen printing stencils 6 are slidably connected between the inner sides of the mounting plates 8, three second magnetic suction blocks 7 are connected to the upper sides of the left and right parts of the screen printing stencils 6, the second magnetic suction blocks 7 can be adsorbed to the adjacent first magnetic suction blocks 5, so as to fix the screen printing stencils 6.
[0020] As shown in Figure 1 , Figure 3 and Figure 4 , further comprising mounting seats 9, the front sides of the mounting plates 8 are connected to the mounting seats 9, connecting pieces 10 are rotatably connected to the mounting seats 9, first clamping bolts 11 are slidably connected to the connecting pieces 10, the lower parts of the first clamping bolts 11 are double circular ring structures, first springs 12 are connected between the first clamping bolts 11 and the adjacent connecting pieces 10, mounting pieces 13 are connected to the front sides of the connecting arms 3, second clamping bolts 14 are slidably connected to the mounting pieces 13, the second clamping bolts 14 can lock the adjacent first clamping bolts 11 after rotation, the inner sides of the second clamping bolts 14 are inclined surface structures, which are beneficial to sliding into the adjacent first clamping bolts 11 and locking them, and second springs 15 are connected between the second clamping bolts 14 and the adjacent mounting pieces 13.
[0021] It should be noted that the PCB is an important component for connecting and supporting electronic components in electronic equipment, and the PCB forms a circuit network by laying a conductive path on an insulating substrate to realize electrical connection between electronic components. In the PCB production process, information such as text, symbols, and signs is printed on the PCB through a silk-screen process, which helps the installation, detection, and maintenance of components. First, the connecting arm 3 and the silk-screen template 6 are lifted upward by the electric mounting frame 2 to leave space for placing the PCB under the template. After the PCB is placed, the template is moved downward by the electric mounting frame 2, and then the silk-screen operation is performed. Since the template may be worn out after long-term use in the silk-screen process, which may cause the printing accuracy to decrease and the pattern to be unclear, affecting the silk-screen effect, the first clamping bolt 11 can be pulled downward to compress the first spring 12, and the first clamping bolt 11 makes the adjacent connecting piece 10 and the mounting plate 8 disengage from the locking state. Then, the connecting piece 10 is rotated upward until the first clamping bolt 11 contacts and presses the adjacent second clamping bolt 14, so that the second spring 15 is compressed until the second clamping bolt 14 is clamped into the ring on the upper side of the adjacent first clamping bolt 11, so that the second clamping bolt 14 locks the adjacent first clamping bolt 11. Then, the silk-screen template 6 is pulled out and a new silk-screen template 6 is replaced. The second magnetic block 7 is attracted to the corresponding first magnetic block 5 to fix the silk-screen template 6, and then the first clamping bolt 11 is reset to complete the replacement of the silk-screen template 6. This way makes the replacement of the silk-screen template 6 more convenient, saves time for replacing the silk-screen template 6, and is beneficial to improving the silk-screen efficiency of the PCB.
