[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-6 As shown, a circuit board opening device includes: The clamping part is used to place the circuit board 1, clamp and fix the placed circuit board 1, and can also remove the circuit board 1 placed on the clamping part; A guide section is provided on the clamping section. The guide section is used to receive the circuit board 1 that is removed from the clamping section and to transfer the received circuit board 1 from the guide section. An opening portion is provided above the clamping portion and is used to make an opening for the circuit board 1.

[0019] Furthermore, the clamping part includes a base frame 2, with support legs 3 on the lower surface of the base frame 2, a limit plate 4 on the upper end of the base frame 2, a fixing plate 5 on the side of the limit plate 4, and a U-shaped movable frame 6 on the fixing plate 5. The two ends of the movable frame 6 are slidably connected to the fixing plate 5, and the two ends of the movable frame 6 are connected to the limit plate 4 by an elastic band 7. Grooves are respectively provided at both ends of the movable frame 6, and elastic limit blocks 8 are provided inside the grooves. Through holes are provided on the limit blocks 8. A movable plate 9 is provided at the upper end of the base frame 2, and the fixing plate 5... The movable plate 9 is provided with discharge holes 10. The movable plate 9 is provided with a fixed frame 11. The fixed frame 11 is provided with top rods 12 at both ends. The end of the top rod 12 is provided with a spindle-shaped protrusion 13. The protrusion 13 can pass through the through hole on the limiting block 8. The lower surface of the fixed frame 11 is provided with a vertical plate 14. The fixed frame 11 and the vertical plate 14 are provided with guide rods 15. The guide rods 15 pass through the bottom frame 2 and are slidably connected to the bottom frame 2. The outer side of the bottom frame 2 is provided with an electric push rod 16. The output end of the electric push rod 16 is fixedly connected to the vertical plate 14.

[0020] In its initial state, under the action of the electric push rod 16, the fixed frame 11 contacts the bottom frame 2, and under the action of the elastic band 7, the movable frame 6 contacts the limiting plate 4. When the clamping part is in this initial state, the circuit board 1 is placed onto the clamping part. Specifically, the circuit board 1 is first placed into the movable frame 6, and the fixed plate 5 supports the circuit board 1. The width of the fixed plate 5 is greater than half the width of the circuit board 1. In this application, the width of the fixed plate 5 is about 3 / 5 of the width of the circuit board 1. Therefore, even if the fixed plate 5 can support part of the circuit board 1, the circuit board 1 can be placed horizontally on the fixed plate 5. After the circuit board 1 is placed, the electric push rod 16 is activated. The output end of the electric push rod 16 extends and pushes the fixed frame 11 and the movable plate 9 towards the fixed plate 5. The front end of the movable plate 9 is set with a chamfer or rounded corner. This ensures that the movable plate 9 can enter below the circuit board 1. After the circuit board 1 abuts against the fixed frame 11, the electric push rod 16 applies a certain clamping force to the fixed frame 11 and the movable frame 6 to fix the circuit board 1 between the movable frame 6 and the fixed frame 11. During this process, the protrusion 13 on the front end of the push rod 12 passes through the through hole on the limiting block 8. The limiting block 8 is made of rubber or silicone. After the circuit board 1 is clamped and fixed, it can be opened through the opening part. The opening on the circuit board 1 is a bolt fixing hole. The circuit board 1 is still in a state where no electronic components are installed. The position of the discharge hole 10 on the fixed plate 5 and the movable plate 9 is opposite to the position of the bolt fixing hole on the circuit board 1. At the same time, the diameter of the discharge hole 10 is 1.5 times or more the diameter of the bolt fixing hole, thereby avoiding contact between the opening part and the fixed plate 5 and the movable plate 9.

[0021] After the opening of the circuit board 1 is completed through the opening section, the opening section separates from the circuit board 1. At this time, the electric push rod 16 is activated, and the output end of the electric push rod 16 retracts, driving the fixed frame 11 to move towards the bottom frame 2. Since the protrusion 13 on the top rod 12 passes through the through hole on the limiting block 8, when the fixed frame 11 moves, it can drive the movable frame 6 to move with the fixed frame 11 through the resistance between the protrusion 13 and the limiting block 8. At the same time, the elastic band 7 begins to be stretched. When the part of the circuit board 1 on the fixed plate 5 is less than 1 / 2, the tension of the deformed elastic band 7 on the movable frame 6 is greater than the friction between the protrusion 13 and the limiting block 8. The protrusion 13 exits through the through hole of the limiting block 8. When the inner part is disengaged, the protrusion 13 disengages from the limiting block 8. Under the action of the elastic band 7, the movable frame 6 moves towards the limiting plate 4. The fixed frame 11 and the movable plate 9 continue to move towards one side of the bottom frame 2. Since the width of the movable plate 9 is small, the friction between the circuit board 1 and the movable plate 9 is less than the friction between the circuit board 1 and the fixed plate 5. Therefore, the movable plate 9 can be moved out from under the circuit board 1. When the movable plate 9 is completely moved out from under the circuit board 1, the circuit board 1 on the fixed plate 5 will fall off the fixed plate 5 under the action of gravity and be guided out by the guide part. The circuit board 1 that falls off the guide part can be received by the collection frame or the conveyor belt.

[0022] Furthermore, a compressible pad 17 is provided on the side of the fixing frame 11. The pad 17 is made of rubber or silicone so that the circuit board 1 can be effectively clamped and fixed by the compression of the pad 17, and the circuit board 1 can be avoided from being damaged by excessive compression.

[0023] Furthermore, the guide section includes a guide platform 18 disposed within the base frame 2, and the surface of the guide platform 18 is inclined.

[0024] Furthermore, the opening section includes a vertical rod 19 mounted on the limiting plate 4 and the bottom frame 2. The upper end of the vertical rod is connected through the top plate 20. It also includes a mounting plate 21, which is slidably connected to the vertical rod 19. An electric push rod 22 is mounted on the top plate 20. The output end of the electric push rod 22 is fixedly connected to the mounting plate 21. Several motors 23 are mounted on the mounting plate 21. A drill bit 24 is mounted on the output end of each motor 23.

[0025] After the circuit board 1 is clamped and fixed by the fixed frame 11 and the movable frame 6, the drilling of the circuit board 1 begins. Specifically, all motors 23 are started and drive the drill bit 24 to rotate. Then, the electric push rod 22 is started, and the electric push rod 22 pushes the mounting plate 21 to move downward. When the mounting plate 21 moves downward, it can drill the circuit board 1 through the high-speed rotating drill bit 24. After the drilling of the circuit board 1 is completed, the output end of the electric push rod 22 retracts, driving the mounting plate 21 to move upward and causing the high-speed rotating drill bit 24 to move out of the circuit board 1. When the drill bit 24 is moved out of the circuit board 1, the motors 23 stop working. When there is an appropriate distance between the mounting plate 21 and the fixed plate 5, the electric push rod 22 stops moving. This distance is so that the operator can place the circuit board 1 on the fixed plate 5.

[0026] Electric push rod 16, electric push rod 22, and motor 23 are all controlled by a PLC system. The operator only needs to place circuit board 1 on the fixed plate 5. The opening and unloading of circuit board 1 are controlled by the PLC system.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
