[0036] Reference Figures 1 to 6 As shown, a circuit board edge device comprises a base and a bracket, wherein the bracket is fixed on the top of the base;

[0037] It also includes a controller, a cutting mechanism, a fixing mechanism and a material moving mechanism;

[0038] The cutting mechanism is arranged at the top of the bracket, and the cutting mechanism comprises a bidirectional screw slide 1, two gong knives 2 and two lifting components 3. The bidirectional screw slide 1 is fixedly arranged at the top of the bracket, and two sliders 4 are symmetrically arranged on the bidirectional screw slide 1. Each lifting component 3 is fixedly arranged on a slider 4, and each gong knife 2 is arranged on a lifting component 3;

[0039] The material transfer mechanism is arranged on the top of the base, and the material transfer mechanism includes a material table 5 and a transfer assembly 6. The transfer assembly 6 is arranged on the top of the base, and the material table 5 is arranged on the transfer assembly 6;

[0040] The fixing mechanism is arranged on the outer wall of the material table 5, and the fixing mechanism includes a driving component 7, two material trays 8, two rotating components 9 and two clamping components 10. The driving component 7 is arranged on the material table 5, and the two material trays 8 are symmetrically arranged on the top of the material table 5. Each rotating component 9 is arranged on the material table 5, and each clamping component 10 is arranged on the top of the material table 5. The driving component 7, the transfer component 6 and each lifting component 3 are electrically connected to the controller.

[0041] Reference Figures 1 to 6As shown, the transfer assembly 6 includes a first motor 11, a screw rod 12, a connecting block 13 and two slide columns 14. The two slide columns 14 are slidably arranged on the top of the base through two slide rails. The material table 5 is fixed on the top of the two slide columns 14. The screw rod 12 is rotatably arranged on the top of the base through two support plates 27. The first motor 11 is fixed on one of the support plates 27. One end of the screw rod 12 is fixedly connected to its output end. The connecting block 13 is fixedly arranged at the bottom of the material table 5, and the connecting block 13 is threadedly connected to the screw rod 12. The first motor 11 is electrically connected to the controller. When the two circuit boards are respectively placed in the two material trays 8, the first motor 11 is started through the controller, so that its output end drives the screw rod 12 to rotate. Since the screw rod 12 is threadedly connected to the connecting block 13, the connecting block 13 is fixedly connected to the material table 5. Under the cooperation of the two slide columns 14 and the two slide rails, the material table 5 and the two circuit boards on its top slide toward one end close to the gong cutter 2.

[0042] Reference Figures 1 to 6 As shown, the driving assembly 7 includes a second motor 15, a rotating shaft 16, two worms 17 and two worm wheels 18. The rotating shaft 16 is rotatably arranged at the bottom of the material table 5 through two mounting plates. The second motor 15 is fixed on one of the mounting plates, and its output end is fixedly connected to one end of the rotating shaft 16. The two worms 17 are fixed on the rotating shaft 16. The two worm wheels 18 are rotatably arranged at the bottom of the material rack through a hinge shaft. Each worm 17 is meshed and connected with a worm wheel 18. When the size of the circuit board of the required gong edge changes, the required material tray 8 must also be removed in order to replace a suitable material tray for placing the circuit board to be processed. The material tray 8 of the road plate, and the existing material tray 8 is generally fixedly connected to the material table 5 by a number of bolts, which is time-consuming and labor-intensive to disassemble, reduces the replacement efficiency, and thus affects the gong edge processing of the circuit board. When the material tray 8 needs to be replaced, the second motor 15 is started by the controller to rotate its output end. Since the output end of the second motor 15 is fixedly connected to the rotating shaft 16, the two worms 17 are fixedly connected to the rotating shaft 16, and each worm wheel 18 is rotatably connected to the material table 5 through an articulated shaft, and each worm 17 is meshedly connected to a worm wheel 18, thereby driving the two articulated shafts to rotate through the two worm wheels 18.

[0043] Reference Figures 1 to 6 As shown, each rotating assembly 9 includes a turntable 19 and two connecting rods 20. The turntable 19 is fixed on one of the hinge shafts, and each connecting rod 20 is hinged on the outer wall of the turntable 19. When the hinge shaft rotates, since the turntable 19 is fixedly connected to the hinge shaft, each connecting rod 20 is hinged to the outer wall of the turntable 19, thereby driving the two connecting rods 20 to rotate synchronously.

[0044] Reference Figures 1 to 6As shown, each clamping assembly 10 includes two T-shaped slides 21 and four pressure blocks 22. Each T-shaped slide 21 is slidably disposed on the top of the material table 5. The bottom of each T-shaped slide 21 is hinged to one end of a connecting rod 20 away from the turntable 19. The four pressure blocks 22 are respectively fixed to the tops of the two T-shaped slides 21 through four connecting rods. When the two connecting rods 20 rotate synchronously, since each T-shaped slide 21 is slidably connected to the material table 5, the bottom of each T-shaped slide 21 is hinged to one end of a connecting rod 20 away from the turntable 19, and the four pressure blocks 22 are respectively fixedly connected to the tops of the two T-shaped slides 21 through four connecting rods, thereby driving the four pressure blocks 22 to move away from each other.

[0045] Reference Figures 1 to 6 As shown, four grooves 23 are symmetrically arranged on the outer walls at both ends of each material tray 8, and each pressing block 22 is plugged into a groove 23. Since four grooves 23 are symmetrically designed on the outer walls at both ends of each material tray 8, and each pressing block 22 is plugged into a groove 23, when the four pressing blocks 22 move away from each other, the four pressing blocks 22 are no longer plugged into the four grooves 23, thereby unlocking the material tray 8. The worker can directly remove the material tray 8 from the top of the material table 5, and then put two new material trays 8 on the top of the material table 5, and then reverse the second motor 15 through the controller, thereby resetting the eight pressing blocks 22 and pressing the two material trays 8 to achieve the replacement effect.

[0046] Reference Figures 1 to 6 As shown, each lifting assembly 3 includes a cylinder 24, a push block 25 and an L-shaped plate 26.

The push block 25 is fixedly arranged between the output end of the cylinder 24 and the L-shaped plate 26. The cylinder 24 is electrically connected to the controller. When the two circuit boards slide to the bottom of the two gong knives 2, the cylinder 24 is started by the controller. Since the cylinder 24 is fixedly connected to the support plate 27, the output end of the cylinder 24 and the L-shaped plate 26 are respectively fixedly connected to the two ends of the push block 25, and the L-shaped plate 26 is slidably connected to the guide rail 28, thereby driving the L-shaped plate 26 to descend.

[0047] Reference Figures 1 to 6 As shown, a third motor 29 is inserted at the top of each L-shaped plate 26, and its output end is fixedly connected to the gong cutter 2. The third motor 29 is electrically connected to the controller. When the L-shaped plate 26 descends, the third motor 29 is started by the controller. Since each L-shaped plate 26 is fixedly connected to a third motor 29, and its output end is fixedly connected to the gong cutter 2, the rotating gong cutter 2 descends toward the circuit board, and cooperates with the bidirectional screw slide 1 and the transfer assembly 6 to realize the longitudinal and lateral sliding of the gong cutter 2, and perform gong edge operations on the circuit board.

[0048] Reference Figures 1 to 6 As shown, four blocks 30 are symmetrically arranged on the inner wall of each tray 8, and each block 30 is fixedly connected to the inner wall of the tray 8. When the circuit board is edged, two circuit boards are first placed in the two trays 8 respectively, so that the four sides of each circuit board are tightly attached to the four inner walls of a tray 8. The four blocks 30 support the circuit boards, so that a gap is reserved between the circuit boards and the inner bottom of the tray 8.

[0049] Reference Figures 1 to 6 As shown, eight guide rods 31 are fixedly provided on the top of the material table 5, and each T-shaped slide plate 21 is slidably connected to two of the guide rods 31. The guide rods 31 provide a limiting effect when the T-shaped slide plate 21 slides, so that the T-shaped slide plate 21 slides more smoothly, thereby making the two pressing blocks 22 slide more smoothly.
