[0027] The adjustment and installation mechanism 2 includes a biaxial motor 201. The biaxial motor 201 is fixedly installed in the inner cavity of the base 1. Output ends on both sides of the biaxial motor 201 are fixedly connected with transmission rods 202.

The top of the positioning rod 205 penetrates through the top of the limiting plate 3 and is fixedly connected with a circular gear 206. The surface of the circular gear 206 is meshed with a toothed plate 207. Opposite sides of the two toothed plates 207 are fixedly connected with limiting shells 208. A bearing plate 209 is fixedly connected between opposite sides of the two limiting shells 208. An L-shaped bracket 210 is arranged on the top of the bearing plate 209. A limiting rod 211 is slidably connected in the inner cavity of the bearing plate 209. The number of the limiting rods 211 is four. A positioning block 212 is fixedly connected between the tops of every two limiting rods 211. The bottoms of the four limiting rods 211 are all fixedly installed with pulleys 213. The bottoms of the pulleys 213 are in contact with the top of the bearing plate 209. By setting the adjustment and installation mechanism 2, the PCB board can be conveyed.

After cutting is completed, the limit on the PCB board is released, which is convenient for the staff to take, thereby improving the processing efficiency of the PCB board.

[0028] Refer to Figure 4 , the surfaces of the two transmission rods 202 are both rotatably connected with connecting rods 214 through bearings. The tops of the connecting rods 214 are fixedly connected with the bottom of the limiting plate 3. By setting the cooperation of the bearing and the connecting rod 214, the transmission rod 202 can be limited, thereby improving the stability of the transmission rod 202 during use.

[0029] Refer to Figure 3 , a retaining rod 215 is fixedly connected between opposite sides of the two toothed plates 207. The material of the retaining rod 215 is metal. By setting the retaining rod 215 made of metal, the stability of the toothed plate 207 during use can be improved, and the position deviation of the toothed plate 207 during use can be avoided.

[0030] Refer to Figure 4 , limiting blocks 216 are fixedly connected to opposite sides of the two L-shaped brackets 210. Bolts 217 are threadedly connected in the inner cavities of the limiting blocks 216. Threaded holes 218 which are matched with the bolts 217 are opened on the top of the bearing plate 209. The number of the threaded holes 218 is several. By setting the cooperation of the limiting blocks 216, the bolts 217 and the threaded holes 218, the position of the L-shaped bracket 210 can be adjusted, thereby facilitating the staff to install PCB boards of different sizes.

[0031] Refer to Figure 4 and Figure 5, a return spring 219 is sleeved on the surface of the limit rod 211. One end of the return spring 219 is fixedly connected to the positioning block 212, and the other end of the return spring 219 is fixedly connected to the top of the bearing plate 209. By providing the return spring 219, the limit rod 211 can be reset, thereby improving the disassembly efficiency of the PCB board.

[0032] Refer to Figure 3 and Figure 5 , two sliding grooves 10 are formed in the top of the bearing plate 209, and the surface of the limit shell 208 is slidably connected to the inner wall of the sliding groove 10. By providing the sliding grooves 10, the limit shell 208 can be limited, thereby improving the stability of the movement of the limit shell 208.

[0033] Refer to Figure 5 , a support frame 11 is fixedly connected to one side of the inclined guide plate 9, and the bottom of the support frame 11 is fixedly connected to the top of the limit plate 3. By providing the support frame 11, the inclined guide plate 9 can be supported and positioned to prevent the position of the inclined guide plate 9 from shifting during use.

[0034] Working principle: When in use, the staff can limit PCBs of different sizes by moving the positions of the two L-shaped brackets 210. After the two L-shaped brackets 210 are moved to the designated positions, the staff fixes them with bolts 217. Then, the PCB is placed on the tops of the two positioning blocks 212, and the external control switch is used to start the dual-shaft motor 201. The output ends on both sides of the dual-shaft motor 201 drive the two transmission rods 202 to rotate. When the two transmission rods 202 rotate, they drive the two first bevel gears 203 to rotate. Since the two first bevel gears 203 are arranged in the same direction, the two first bevel gears 203 can drive the two second bevel gears 204 to rotate in the same direction when rotating. When the two second bevel gears 204 rotate in the same direction, they drive the two positioning rods 205 to rotate. When the two positioning rods 205 rotate, they drive the two circular gears 206 to rotate. When the two circular gears 206 rotate, they drive the two toothed plates 207 to move. When the two toothed plates 207 move, they drive the two limit shells 208 to move in the inner cavity of the chute 10. When the two limit shells 208 move, they drive the bearing plate 209 and the two L-shaped brackets 210 to move. When the bearing plate 209 moves, it drives the limit rod 211 in the inner cavity to move. When the limit rod 211 moves, it drives the positioning block 212 on the top and the pulley 213 at the bottom to move. When the pulley 213 moves and contacts the inclined guide plate 9, the inclined guide plate 9 squeezes the pulley 213, so that the pulley 213 drives the limit rod 211 and the positioning block 212 to move upward. When the positioning block 212 moves upward, it stretches the return spring 219 and clamps and positions the PCB. Then, the staff uses the external control switch to start the electric telescopic rod 5, and the telescopic end of the electric telescopic rod 5 drives the positioning frame 6 and the cutting knife 8 to move downward, and the cutting process of the PCB can be completed. After the cutting process is completed, the adjustment and installation mechanism 2 is used to drive the PCB to move forward. When the pulley 213 disengages from the inclined guide plate 9, under the reaction force of the return spring 219, the limit rod 211 drives the positioning block 212 and the pulley 213 to move downward, and the limitation of the PCB can be released, thus facilitating the staff to take it.

[0035] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
