Description

Technical Field

[0001] The invention relates to the technical field of circuit board production, and in particular to a circuit board breaking and separating device. Background Art

[0002] Circuit board, also known as printed circuit board, is one of the indispensable components in modern electronic equipment. It plays the role of connecting and supporting electronic components and realizing the electrical connection between various components in the circuit. The circuit board is mainly composed of insulating substrate, copper foil conductive layer, protective coating, etc., and is arranged with preset conductive paths (traces) and other electronic interconnection structures to carry and connect electronic components, such as resistors, capacitors, integrated circuits, transistors, etc., to form predetermined circuit functions; commonly used circuit boards are not large in area, and companies usually produce them in batches by splicing panels, and then divide the spliced ​​panels into small boards, so circuit board depaneling is an important part of the circuit board production process.

[0003] At present, there are two main ways to separate circuit boards: manual and mechanical. Manual separation mainly uses the method of manual breaking to separate circuit boards. Usually, V-shaped grooves are reserved between adjacent circuit boards during mass production of panels. Manual separation only requires breaking the circuit boards along the V-groove, while mechanical separation uses cutting to separate circuit boards. However, all of the above methods have certain defects. When separating circuit boards by manual breaking, it is necessary to control the appropriate force during operation. If the force is too small, the circuit boards cannot be broken apart, and if the force is too large, the electronic components of the circuit boards are easily damaged. Therefore, the manual breaking method is more troublesome and less efficient, while the mechanical cutting method is not only costly, but also the cutting parts are prone to generate heat due to friction when cutting the circuit boards, which may burn the circuit boards.

[0035] When in use, according to the length of the circuit board, the servo motor 14 drives the bidirectional screw rod 15 to rotate or reverse, thereby driving the two movable frames 2 and the two belt conveyors Ⅰ3 to move closer to or farther away from each other, and then adjusting the distance between the two movable frames 2 to adapt to circuit boards of different lengths, and when the circuit board is placed between the two belt conveyors Ⅰ3, the waste on the front and back sides can be extended. After adjustment, the two connected circuit boards are placed on the belt conveyor Ⅰ3, and then the two connected circuit boards are conveyed to the left by the belt conveyor Ⅰ3, so that the two connected circuit boards are The circuit board gradually moves between the two fixing frames 5. When the two connected circuit boards move between the two distance sensors Ⅰ17, the distance sensor Ⅰ17 will sense the distance between the circuit boards. At this time, the distance sensor Ⅰ17 will sense that the distance between the circuit boards is less than the preset value, and the distance sensor Ⅰ17 will send a signal. After receiving the signal, the controller 16 controls the belt conveyor Ⅰ3 to stop conveying the two connected circuit boards, so that the two connected circuit boards stop moving. At this time, the waste on the front and rear sides of the circuit board just touches the bottom of the breaking plate 8, and then the controller 16 will control the cylinder Ⅰ19 drives the pressing block Ⅰ20 to move downward until the pressing block Ⅰ20 presses the two connected circuit boards, thereby limiting the position of the two connected circuit boards. Then the controller 16 controls the electric push rod Ⅰ6 to drive the rotating frame Ⅰ7 to move downward, so that the rotating frame Ⅰ7 squeezes the breaking plate 8 to rotate, so that the breaking plate 8 squeezes the waste on the front and back sides of the circuit board to rotate, and then the breaking plate 8 breaks the waste on the front and back sides of the circuit board (a V-shaped groove will be reserved between the circuit board and the waste so as to break the waste from the circuit board). After the waste on the front and back sides of the circuit board is broken, the waste will be separated from the electric push rod Ⅰ6. The road plate falls, and then the controller 16 will control the electric push rod Ⅰ6 to drive the rotating frame Ⅰ7 to move upward and reset, so that the rotating frame Ⅰ7 pulls the breaking plate 8 to rotate in the opposite direction and reset. At the same time, the controller 16 will control the cylinder Ⅰ19 to drive the pressing block Ⅰ20 to move upward and reset, so that the pressing block Ⅰ20 releases the limit on the circuit board. After that, the controller 16 will control the belt conveyor Ⅰ3 to continue to convey the two connected circuit boards to the left. At the same time, the controller 16 will also control the belt conveyor Ⅱ4 to assist in conveying the two connected circuit boards. In this way, the waste on the front and back sides of the circuit board can be automatically broken and separated;

[0036] When the two connected circuit boards move to the left onto the support frame III 10 and the folding plate 12, the distance sensor II 18 will sense the distance between the circuit boards.

After receiving the signal, the controller 16 will control the belt conveyor I 3 and the belt conveyor II 4 to stop conveying the two connected circuit boards, so that the two connected circuit boards stop moving. At this time, the two connected circuit boards are just at the top of the support frame III 10 and the folding plate 12 (the circuit board on the left is at the folding plate 1 2 top, the circuit board on the right is on the top of the support frame III 10, and the circuit board on the right is not completely separated from the belt conveyor I 3 and the belt conveyor II 4), then the controller 16 will control the cylinder II 21 to drive the pressing block II 22 to move downward until the two pressing blocks II 22 respectively press the two circuit boards, thereby limiting the two connected circuit boards, and then the controller 16 will control the telescopic rod of the electric push rod II 11 to extend, so that the telescopic rod of the electric push rod II 11 squeezes the folding plate 12 to rotate, so that the folding plate 12 drives the circuit board on the left to rotate along the V-shaped groove, and then the folding plate 12 breaks the circuit board on the left, and at the same time the controller 16 will control the cylinder II 2 on the left 1 drives the pressing block II 22 to move upward, so that the pressing block II 22 on the left side releases the circuit board on the left side, and keeps the pressing block II 22 on the left side in contact with the circuit board on the left side, so that the pressing block II 22 on the left side can continuously limit the circuit board on the left side, so that when the circuit board on the left side bounces off at the moment of breaking, the pressing block II 22 on the left side can limit the circuit board on the left side, so that the circuit board on the left side can be stably leaned against the folding plate 12 after breaking, and after the circuit board on the left side is broken, the circuit board on the left side will be separated from the circuit board on the right side, and then the controller 16 will control the telescopic rod of the electric push rod II 11 to shorten, so that the telescopic rod of the electric push rod II 11 pulls the folding plate 12 to rotate in the opposite direction and reset, and at the same time the controller 16 will control the cylinder II 21 Drive the pressing block Ⅱ22 to move upward and reset, so that the two pressing blocks Ⅱ22 are separated from the two circuit boards respectively, thereby releasing the limit of the two circuit boards, and then the controller 16 will control the belt conveyor Ⅰ3 and the belt conveyor Ⅱ4 to continue to convey the circuit board on the right, so that the circuit board on the right pushes the circuit board on the left to enter the roller frame 13 for unloading (the circuit board on the right side that has been broken will continue to push the circuit board on the left side to move to the left until the circuit board on the left side has been broken) until the circuit board on the right is separated from the belt conveyor Ⅰ3 and the belt conveyor Ⅱ4. In this way, the two connected circuit boards can be automatically broken and separated, and then the above operation can be repeated.

[0038] By setting the guide plate I23 and the guide plate II24, when the belt conveyors I3 and II4 convey the two connected circuit boards to the left, the guide plates I23 and II24 can guide the two connected circuit boards to prevent the two connected circuit boards from shifting forwards and backwards when conveying to the left, thereby affecting the subsequent breaking work of the circuit boards.

[0040] When in use, the pull rod 30 can be pulled to move rightward, the spring 31 is compressed, and the tooth block 29 is moved away from the tooth groove 32 of the pull rod 30, so that the pull rod 30 releases the limit of the rotating frame II 26, and then the rotating frame II 26 is pulled to rotate, so that the rotating frame II 26 does not affect the placement of the circuit board between the two material discharging frames 25, and then the pull rod 30 is released, the spring 31 is restored to its original state, and the spring 31 drives the pull rod 30 to move leftward and reset, so that the tooth block 29 is re-engaged in the tooth groove 32, so that the pull rod 30 The rotating frame II 26 is limited; then two appropriate connected circuit boards are stacked in sequence between the two unloading frames 25, and the circuit board at the bottom is in contact with the conveyor belt of the belt conveyor I3, and then the pull rod 30 is pulled to the right again to release the limit of the rotating frame II 26 by the pull rod 30, and then the rotating frame II 26 is pushed to reverse and reset, and the pull rod 30 is released again to limit the rotating frame II 26 by the pull rod 30 again, and then the pressure plate 28 is driven to the right by the cylinder III 27. The pressing plate 28 moves downward to press the uppermost circuit board; when it is necessary to convey the two connected circuit boards to the left through the belt conveyor Ⅰ3, the belt conveyor Ⅰ3 only needs to work to make the belt conveyor Ⅰ3 convey the two connected circuit boards at the bottom between the two material discharging frames 25 to the left, and then the cylinder Ⅲ27 is used to drive the pressing plate 28 to move downward at a fixed time, so that the pressing plate 28 can squeeze the remaining circuit boards in the two material discharging frames 25 and move downward at a fixed time (and this downward pressing method can prevent the circuit boards from being stuck between the two material discharging frames 25 due to friction compared to the natural gravity fall), so that the lowermost circuit board contacts the conveyor belt of the belt conveyor Ⅰ3, so that the belt conveyor Ⅰ3 can always convey the lowermost circuit board to the left, thereby realizing automatic loading of the two connected circuit boards; finally, when all the circuit boards between the two material discharging frames 25 have been conveyed, the cylinder Ⅲ27 is used to drive the pressing plate 28 to move upward and reset.

The one-way screw rod Ⅰ35 is threadedly connected so that when the one-way screw rod Ⅰ35 rotates, it can drive the movable frame 36 to move on the support frame 33; two reduction motors Ⅱ37 are symmetrically arranged on the left side of the movable frame 36; two one-way screw rods Ⅱ38 are symmetrically rotatably arranged on the front and back sides of the movable frame 36, and the left ends of the two one-way screw rods Ⅱ38 are respectively connected to the output shafts of the two reduction motors Ⅱ37; the collecting frame 39 is slidably installed on the movable frame 36, and the collecting frame 39 is threadedly connected with the two one-way screw rods Ⅱ38, so that when the two one-way screw rods Ⅱ38 rotate, they can drive the collecting frame 39 to move on the movable frame 36.

[0042] When in use, the tray with grids can be placed in the collection frame 39; when the broken circuit board is discharged to the left through the roller frame 13, the broken circuit board will fall into the specified grid in the tray, and then the one-way screw rod I35 is driven by the reduction motor I34 to rotate forward and reverse, so that the one-way screw rod I35 drives the movable frame 36, the reduction motor II37, the one-way screw rod II38 and the collection frame 39 to move forward or backward, and then the one-way screw rod II38 is driven by the reduction motor II37 to rotate forward and reverse, so that the collection frame 39 can move left or right, so as to drive the collection frame 39 to move left or right. The tray in the collection frame 39 moves forward or backward or left or right in sequence, thereby adjusting the position of the tray so that the broken circuit boards can fall into different grids in sequence when they fall into the tray, thereby realizing the separate placement of the broken circuit boards (separate placement can avoid the pressure of stacking circuit boards when the circuit boards are stacked, which may cause the circuit boards to bend or deform, especially for thinner or fragile circuit boards, long-term pressure may also damage the solder joints and component feet, affecting the electrical connection and mechanical stability of the circuit board).
