Description
Technical Field
[0001] The invention relates to the technical field of circuit board processing, and in particular to a FPCB board laser cutting device. Background Art
[0002] The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, ultra-thin circuit boards, ultra-thin circuit boards, printed circuit boards, etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts. Circuit boards can be called printed circuit boards or printed circuit boards. Circuit boards are divided into flexible boards (FPC), rigid boards (PCB) and flexible and rigid boards (FPCB) according to their characteristics. During the processing of FPCB boards, the entire FPCB board needs to be cut into multiple single boards. In order to reduce the burrs of the circuit board cuts after cutting, lasers are usually used to cut the circuit board into single boards, and then the cut single boards are buckled off the entire circuit board.
[0003] A Chinese patent application with publication number CN114799549A discloses a molded circuit board cutting device and a cutting method. The molded circuit board cutting device and the cutting method can adsorb and fix the entire circuit board to be cut on the suction plate mainly through the cooperation of a suction plate, a first motor and a suction fan, and then drive the laser cutting head to move along the X-axis and the Y-axis through the cooperation of a first electric slide, a second electric slide and a laser cutting head, so as to facilitate cutting at different positions of the entire circuit board, so that the entire circuit board is cut into multiple single PCS circuit boards, and then drive the suction plate to flip 180 degrees through the first motor, so as to facilitate turning the single PCS circuit board adsorbed by the suction plate into the collection tray on the support plate, without the need for personnel to take and place them one by one, thereby improving the material taking rate of the single PCS circuit board to a certain extent.
[0004] However, the structural design of the above-mentioned related technology: although the cut single boards can be collected, after the cutting is completed, the flipped suction plate needs to be reset before the circuit board to be cut can be placed, which makes the cutting steps more complicated, resulting in inconvenience for continuous cutting of the circuit boards, and further leads to low cutting efficiency of the circuit boards.
[0005] Therefore, we propose a FPCB board laser cutting device to solve the above problems. Summary of the invention
[0006] The present invention provides a FPCB laser cutting device, aiming to solve the problem of inconvenience in continuous cutting of circuit boards in the related art.

[0008] Two limit assemblies are respectively installed on both sides of the inner wall of the support frame, and the limit assemblies include a limit plate and a limit block, and both the limit plate and the limit block have inclined surfaces;
[0009] Two driving mechanisms are arranged in the support frame relative to each other, the driving mechanism comprises a transmission member 1 and two transmission rollers 1 arranged up and down, the transmission member 1 is arranged on the two transmission rollers 1, and the transmission rollers 1 are rotatably connected to the support frame;
[0010] A plurality of installation frames are evenly distributed on the transmission member 1, and the installation frames can move along the track of the transmission member 1 to drive the circuit board to move upward;
[0011] Two clamping plates are rotatably connected to two sides of the installation frame respectively, and two slot plates are installed on the clamping plates, and the slot plates have strip grooves;
[0012] The trigger rod is arranged on one side of the clamping plate, and is elastically slidably connected to the mounting frame in the lateral direction. Two connecting rods sliding in the slot plate are installed on the trigger rod. When the mounting frame moves upward, the limit assembly squeezes the trigger rod, and the trigger rod pushes the clamping plate to clamp the circuit board through the connecting rod.
[0013] The beneficial effect is as follows: through the rotation of the transmission roller 1, several installation frames on the transmission member 1 can be driven to move along the trajectory of the transmission member 1. During the movement, the installation frame can continuously support the circuit board and move it upward, so that the circuit board is close to the laser cutting head, so that the circuit board can be continuously loaded. During the upward movement of the installation frame, under the action of the limit plate and the limit block, the limit assembly squeezes the trigger rod, and the trigger rod pushes the clamping plate to clamp the circuit board through the connecting rod. After the cutting is completed, the installation frame between the two limit plates drives the cut circuit board to flip and move downward, which is convenient for the subsequent cutting of the circuit board, so as to achieve the effect of continuous cutting of the circuit board, thereby improving the cutting efficiency of the circuit board.

[0017] Preferably, racks are provided on both sides of the interior of the support frame, and the racks can mesh with gears, wherein one of the racks is located between two limit plates, and the other rack is located between two limit blocks.
[0018] The effect is that when the installation frame moves upward, the rack engages with the gear. As the installation frame continues to move, the gear drives the reel to reel in the connecting rope. At this time, the connecting rope pulls the supporting plate out of the installation frame to support the bottom of the circuit board and prevent the circuit board from bending.

[0020] The effect is that the transmission component 1 drives the transmission component 2 to operate, and the transmission component 2 drives the installation component on the sliding component to move up and down. When the installation component moves upward, it can lift a circuit board upward through the lifting component to feed the material to the installation frame.
[0021] Preferably, the transmission component 2 includes two transmission rollers 2, a transmission member 2, a sliding column and a push block. The two transmission rollers 2 are rotatably connected to the support frame. The transmission component 1 is fixed to one of the transmission rollers 2.

During the movement of the slide column, it can drive the sliding frame to reciprocate along the length direction of the slide rod.
[0024] Preferably, the mounting assembly includes a mounting seat mounted on a sliding frame, the mounting seat is slidably connected to an articulated seat 1, a baffle is mounted on one end of the articulated seat 1, the baffle is located on one side of the push block, and the other end of the articulated seat 1 is hinged to an articulated arm.
[0025] Preferably, the lifting assembly includes a second slide plate and a movable plate, the second slide plate is elastically slidably connected to the mounting seat along the transverse direction, the articulated arm is hinged to the second slide plate, the movable plate is installed on the second slide plate, the second slide plate is elastically slidably connected to a limiting member along the vertical direction, and the mounting seat and the second slide plate are both provided with limiting holes for the limiting member to pass through.
[0026] The effect is that when the slide column rises to the limit position, as the transmission member 2 rotates, the slide column starts to move horizontally in the sliding frame, and the slide column pushes the baffle to move horizontally through the push block. At this time, the baffle drives the articulated arm through the articulated seat 1 to pull the movable plate gradually into the mounting seat.

The cutting mechanism is arranged on the top of the supporting mechanism, and there are two driving mechanisms, which are relatively arranged on both sides of the inside of the supporting mechanism. There are multiple supporting mechanisms, and the multiple supporting mechanisms are evenly distributed on the two driving mechanisms. The driving mechanism can drive the supporting mechanisms thereon to move up and down reciprocatingly. There are two feeding mechanisms, and the two feeding mechanisms are located between the two driving mechanisms. The feeding mechanism can drive the circuit board to move up and transfer to the supporting mechanism.
[0046] like Figure 1 and Figure 3 As shown, the support mechanism includes a support frame 11, a feeding assembly 12 and a limiting assembly. The feeding assembly 12 is arranged on one side of the inner bottom wall of the support frame 11.

The limiting assembly includes a limiting plate 13 and a limiting block 14, and there is a spacing between the limiting plate 13 and the limiting block 14. One of the driving mechanisms is arranged between the two limiting plates 13, and the other driving mechanism is arranged between the two limiting blocks 14.
[0047] A flipping and picking assembly 61 is provided on one side of the inner part of the support frame 11, and the flipping and picking assembly 61 is located on one side of the limiting plate 13. It should be noted that the flipping and picking assembly 61 can rotate 180 degrees to remove the cut circuit board and absorb the cut circuit board. Since the flipping and picking assembly 61 is a conventional structure in the prior art, it will not be repeated here.
[0048] like Figure 3 As shown, the limiting plate 13 is L-shaped, and one side of the limiting plate 13 and the limiting block 14 has an inclined surface close to the support frame 11, and the inclined surfaces on the limiting plate 13 and the limiting block 14 are at the same height. The top of the limiting plate 13 and the top of the support frame 11 are at the same horizontal plane.
[0049] like Figures 1 to 3As shown, the loading assembly 12 includes a push-pull plate 121, a telescopic member 122, a discharge plate 123 and two telescopic rods 124.

[0050] The circuit boards are stacked and placed on the unloading plate 123. When a circuit board is taken away, the telescopic member 122 drives the unloading plate 123 to move upward so that the top circuit board is always at the same height.
[0051] like Figure 1 As shown, the cutting mechanism includes an electric slide rail 21, a movable frame 22 and a laser cutting head 23. There are two electric slide rails 21, which are respectively mounted on the tops of both sides of the support frame 11.

[0052] When the feeding mechanism drives the circuit board to move up to the extreme position, the two driving mechanisms drive the supporting mechanisms thereon to move to the bottom of the circuit board on the feeding mechanism. Then, the driving mechanism drives the circuit board to move up and approach the laser cutting head 23 through the supporting mechanism. When it reaches the cutting position, the laser cutting head 23 cuts the circuit board. After the circuit board is cut, the electric slide rail 21 drives the laser cutting head 23 to move to the edge position of the support frame 11 through the movable frame 22, and then the driving mechanism drives the circuit board to be transferred to the top of the flipping and picking assembly 61 through the supporting mechanism.

In this embodiment, the transmission wheel 1 342 and the transmission wheel 2 344 are both pulleys, and the transmission wheel 1 342 and the transmission wheel 2 344 are connected by belt transmission. In other embodiments, the transmission wheel 1 342 and the transmission wheel 2 344 are both sprockets, and the transmission wheel 1 342 and the transmission wheel 2 344 are connected by chain transmission, the connecting shaft 2 343 is installed in the middle of the transmission wheel 2 344, and the feeding mechanism is connected to one end of the connecting shaft 2 343.
[0055] The motor 33 drives the transmission member 1 32 and the two transmission rollers 1 31 to rotate. The transmission roller 1 31 at the bottom drives the transmission wheel 1 342 to rotate through the connecting shaft 1 341, and the transmission wheel 1 342 drives the connecting shaft 2 343 in the transmission wheel 2 344 to rotate through the belt, so that the feeding mechanism can lift the circuit board and move it upward.
[0056] like Figure 1 and Figure 4 As shown, the supporting mechanism includes a lifting component 41, a clamping component 42, a triggering component 43 and a supporting component 44. There are two clamping components 42 and two triggering components 43. The two clamping components 42 are respectively arranged on both sides of the lifting component 41, and the triggering component 43 is arranged on one side of the clamping component 42.
[0057] like Figure 1 , Figure 4 and Figure 6 As shown, the lifting assembly 41 includes a mounting frame 411 and two fixing frames 413.

[0058] During the rotation of the transmission member 32, the installation frame 411 can be driven to move around the track of the transmission member 32. When the installation frame 411 moves upward, the installation frame 411 can drive the circuit board held by the feeding mechanism to move upward.

One side of the slider 435 is equipped with an elastic member 436. In this embodiment, the elastic member 436 is a spring. In other embodiments, the elastic member 436 is an elastic sheet. One end of the elastic member 436 is installed on one side of the inner wall of the mounting groove 414.
[0062] The installation frame 411 located between the two limit plates 13 can drive the trigger rod 432 thereon to move upward during the upward movement, so that the trigger rod 432 contacts the inclined surface on the limit plate 13. As the installation frame 411 continues to move upward, under the action of the limit plate 13, the trigger rod 432 can be pushed close to the support shaft 421. At this time, the trigger rod 432 drives the connecting rod 434 on the fixed plate 433 to move horizontally through the slide plate 431. During the horizontal movement of the connecting rod 434, the connecting rod 434 drives the support shaft 421 to rotate through the slot plate 425, and the support shaft 421 drives the clamping plate 423 to rotate to a horizontal state through the connecting frame 422, thereby clamping one side of the top of the circuit board. During the upward movement of the installation frame 411 located between the two limit blocks 14, the clamping plate 423 thereon can clamp the other side of the top of the circuit board.

There are two connecting ropes 445, one end of which is fixed on the connecting plate 446, and the other end of which is passed around the guide shaft 444 and fixed on the reel 442.

[0066] During the upward movement of the installation frame 411, the gear 443 can mesh with the rack 45. As the installation frame 411 continues to move upward, the rack 45 drives the reel 442 to rotate through the gear 443, and the reel 442 reels the connecting rope 445. The connecting rope 445 pulls the supporting plate 441 through the connecting plate 446 to gradually move out of the installation frame 411, so that the supporting plate 441 supports the bottom of the circuit board to prevent the circuit board from bending downward and affecting the normal cutting of the circuit board.

A sliding groove 524 is provided in the length direction of the sliding frame 523, and the sliding column 513 is slidably connected in the sliding groove 524.
[0070] During the rotation of the second connecting shaft 343, the second connecting shaft 343 drives the slide post 513 on the second transmission member 512 to move around the track of the second transmission member 512 through the second transmission roller 511, and the slide post 513 reciprocates in the first slide groove 524. During the movement of the slide post 513, the slide frame 523 can be driven to reciprocate along the length direction of the slide rod 522.
[0071] like Figure 7 and Figure 8 As shown, the mounting assembly 53 includes a mounting seat 531 mounted on the sliding frame 523, and two guide rods 532 are slidably connected to one side of the mounting seat 531, and there is a distance between the two guide rods 532. In this embodiment, the guide rod 532 is in a T-shape, and one end of the guide rod 532 passes through the mounting seat 531 and extends to the inside of the mounting seat 531. An elastic member 3 533 is sleeved on the outer side of the guide rod 532, one end of the elastic member 3 533 is mounted on one side of the mounting seat 531, and the other end of the elastic member 3 533 is mounted on the end of the guide rod 532. In this embodiment, the elastic member 3 533 is a spring.
[0072] A second slide groove 534 is provided on one side of the mounting seat 531, and the second slide groove 534 is located between the two guide rods 532. An articulated seat 1 535 is slidably connected inside the second slide groove 534. A baffle 536 is installed on one end of the articulated seat 1 535, and the baffle 536 is located on one side of the push block 514. An articulated arm 537 is hinged on the other end of the articulated seat 1 535.
[0073] like Figures 7 to 9As shown, the lifting assembly 54 includes a second slide plate 541, a second hinge seat 542 and a movable plate 543. The second slide plate 541 is slidably connected to the inside of the mounting seat 531, the second hinge seat 542 is mounted on one side of the second slide plate 541, the hinge arm 537 is hinged to the second hinge seat 542, and the movable plate 543 is mounted on the other side of the second slide plate 541. The mounting seat 531 has an opening for the second slide plate 541 to pass through.
[0074] like Fig. 9 As shown, a receiving groove 544 is provided inside the second slide plate 541, and an elastic member 545 is installed on the inner top wall of the receiving groove 544. In this embodiment, the elastic member 545 is a spring, and in other embodiments, the elastic member 545 is an elastic sheet, and a limiting member 546 is installed at the bottom end of the elastic member 545. In this embodiment, the limiting member 546 is columnar and has an arc-shaped bottom end, and in other embodiments, the limiting member 546 is spherical. The bottom of the mounting seat 531 and the second slide plate 541 are both provided with a limiting hole for the limiting member 546 to pass through.
[0075] When the slide post 513 rises to the limit position, as the transmission member 2 512 rotates, the slide post 513 begins to move horizontally in the slide slot 1 524, and the slide post 513 pushes the baffle 536 to move horizontally through the push block 514. At this time, the baffle 536 drives the hinge arm 537 through the hinge seat 1 535 to pull the movable plate 543 gradually into the mounting seat 531, and the elastic member 3 533 is gradually stretched. When the movable plate 543 completely enters the mounting seat 531, the limiting member 546 is inserted into the limiting hole of the mounting seat 531 to limit the movable plate 543 to prevent the movable plate 543 from touching the circuit boards stacked below.
[0076] When the slide column 513 moves down to the extreme position, the mounting seat 531 contacts the mounting plate 521. At this time, the mounting plate 521 squeezes the limit member 546 into the slide plate 2 541. At the same time, the elastic member 3 533 is reset and pushes the movable plate 543 out of the mounting seat 531 through the guide rod 532 to be inserted into the bottom of the circuit board. When the slide column 513 rises again, the slide column 513 can drive a circuit board to move up through the movable plate 543.
[0077] Working principle: When cutting the circuit board, first stack the circuit boards and place them on the unloading plate 123, then start the motor 33, the motor 33 drives the transmission member 1 32 and the two transmission rollers 1 31 to rotate, and then the multiple installation frames 411 move around the track of the transmission member 1 32. The transmission roller 1 31 located below drives the transmission wheel 1 342 to rotate through the connecting shaft 1 341, and the transmission wheel 1 342 drives the connecting shaft 2 343 in the transmission wheel 2 344 to rotate through the belt, and the connecting shaft 2 343 drives the sliding column 513 on the transmission member 2 512 to move around the track of the transmission member 2 512 through the transmission roller 2 511. At the same time, the sliding column 513 drives the sliding frame 523 to reciprocate along the length direction of the sliding rod 522, and when the sliding frame 523 moves upward, it drives the circuit board to move upward through the movable plate 543.
[0078] When the sliding frame 523 moves up to the limit position, the installation frame 411 rotates to the bottom of the circuit board to support the bottom sides of the circuit board. As the transmission roller 131 continues to rotate, the installation frame 411 starts to move upward, the movable plate 543 starts to move downward, and then other installation frames 411 support the circuit board sent up by the movable plate 543 to achieve continuous feeding of the circuit board, thereby continuously cutting the circuit board and improving the cutting efficiency of the circuit board. During the upward movement of the installation frame 411, the rack 45 drives the reel 442 to rotate through the gear 443, and the reel 442 reels the connecting rope 445. The connecting rope 445 pulls the supporting plate 441 to gradually move out of the installation frame 411 through the connecting plate 446, so that the supporting plate 441 supports the bottom of the circuit board.
[0079] As the installation frame 411 continues to move upward, the clamping plate 423 on the installation frame 411 is clamped on the top of the circuit board to fix the circuit board. When the installation frame 411 moves to the welding position of the circuit board, the laser cutting head 23 starts to cut the circuit board to cut the circuit board into single boards, and at this time, the single boards are still retained on the circuit board. When the cutting is completed, the installation frame 411 continues to move upward, the trigger rod 432 located between the two limit plates 13 continues to contact the limit plates 13, and the trigger rod 432 located between the two limit blocks 14 is disengaged from the limit blocks 14. The clamping plate 423 located between the two limit plates 13 continues to clamp the circuit board, and the clamping plate 423 located between the two limit blocks 14 releases the clamping of the circuit board, and at the same time, the rack 45 is disengaged from the gear 443 to reset the support plate 441.
[0080] As the transmission member 32 continues to rotate, the mounting frame 411 begins to move downward. When the circuit board moves to the flipping and picking assembly 61, the flipping and picking assembly 61 absorbs the cut single board and lifts it up. Then the flipping and picking assembly 61 drives the cut single board to move downward to realize the unloading of the single board. After the unloading is completed, the transmission member 32 continues to rotate, and the trigger rod 432 located between the two limit plates 13 disengages from the limit plates 13, so that the clamping plate 423 located between the two limit plates 13 releases the clamping of the circuit board, thereby discarding the waste board to facilitate the support of subsequent circuit boards.

A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
