Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a circuit board shaping device. Background Art

[0002] During the circuit board manufacturing process, to achieve a specific shape, a cutting machine first uses a V-cut method to cut the specific circuit board shape from a large piece of board. Then, to improve the efficiency of subsequent board assembly, the cutting machine cuts the large board into multiple square boards. After the board is assembled, the operator uses pliers to grasp and break off the excess board material on the edge of the board to obtain the board that meets the specified shape. This completes the board shaping process before the board can be shelled. This method of using pliers to break off the excess board material on the edge is slow, reduces the efficiency of the board shaping process, and is not conducive to improving the efficiency of subsequent shelling.

[0042] refer to Figures 1 to 5 According to an embodiment of the present invention, the circuit board shaping device includes:

[0043] A frame 100 is provided with a positioning platform 110, which is used to position the circuit board;

[0044] A first clamping mechanism 200 and a second clamping mechanism 300 are respectively provided on the left and right sides of the positioning platform 110. The first clamping mechanism 200 and the second clamping mechanism 300 can be slidably connected to the frame 100 in the left and right directions. The first clamping mechanism 200 and the second clamping mechanism 300 are respectively used to clamp excess plate materials on the left and right edges of the circuit board on the positioning platform 110;

[0045] The linear drive mechanism 400 is provided on the frame 100 and is used to drive the first clamping mechanism 200 and the second clamping mechanism 300 to move away from or toward each other, so that the circuit board can be placed on the positioning table 110 and between the first clamping mechanism 200 and the second clamping mechanism 300, or so that the first clamping mechanism 200 and the second clamping mechanism 300 can respectively clamp excess plate materials on the left and right edges of the circuit board;

[0046] The first rotary drive mechanism 500 and the second rotary drive mechanism 600 are configured to drive the first clamping mechanism 200 to rotate so that the first clamping mechanism 200 can break off excess plate material on the left edge of the circuit board. The second rotary drive mechanism 600 is configured to drive the second clamping mechanism 300 to rotate so that the second clamping mechanism 300 can break off excess plate material on the right edge of the circuit board.

[0047] The rotation angle limiting device 900 is provided on the frame 100 and is used to limit the rotation angle of the first clamping mechanism 200 and the second clamping mechanism 300 to prevent the first clamping mechanism 200 and the second clamping mechanism 300 from colliding with the circuit board on the positioning platform 110.

[0048] It is understood that when it is necessary to break off and remove excess sheet material on the left and right edges of the circuit board, the linear drive mechanism 400 first drives the first clamping mechanism 200 and the second clamping mechanism 300 away from each other, and then the operator places the circuit board on the positioning table 110. The positioning table 110 can position the circuit board, and then the linear drive mechanism 400 drives the first clamping mechanism 200 and the second clamping mechanism 300 towards each other, so that the first clamping mechanism 200 clamps the excess sheet material on the left edge of the circuit board, and the second clamping mechanism 300 clamps the excess sheet material on the right edge of the circuit board. Then, the first rotary drive mechanism 500 drives the first clamping mechanism 200 to rotate, and the second rotary drive mechanism 600 drives the second clamping mechanism 300 to rotate, so that the first rotary drive mechanism 500 can break off the excess sheet material on the left edge of the circuit board, and the second rotary drive mechanism 600 can break off the excess sheet material on the right edge of the circuit board, thereby making the circuit board conform to the specified shape. During the rotation of the first and second clamping mechanisms 200 and 300, the rotation angle limiting device 900 limits the rotation angle of the first and second clamping mechanisms 200 and 300, preventing the first and second clamping mechanisms 200 and 300 from rotating excessively and damaging the circuit board. This circuit board shaping device simultaneously breaks off excess board material on both sides of the circuit board, improving the efficiency of circuit board shaping and, in turn, facilitating the subsequent assembly of circuit boards.

[0049] It should be explained that the reference Figure 1 and Figure 2 In order to improve the efficiency of circuit board insertion, the circuit boards usually used for insertion are square, with cutting holes left on the circuit boards. The shape of the intermittent cutting holes is the edge shape of the subsequent circuit board that meets the specified shape. The cutting holes on the circuit board in the embodiment of the present invention are the cutting holes on the left and right edges of the circuit board, and the left and right sides of the cutting holes are the excess sheet materials. The first clamping mechanism 200 clamps the excess sheet material on the left edge of the circuit board and then rotates, so that the connection between the excess sheet material on the left edge of the circuit board and the middle sheet material of the circuit board can be broken. Similarly, the second clamping mechanism 300 clamps the excess sheet material on the right edge of the circuit board and then rotates, so that the connection between the excess sheet material on the right edge of the circuit board and the middle sheet material of the circuit board can be broken. The remaining middle part of the circuit board is the circuit board body, and the resulting circuit board meets the specified shape.

[0050] refer to Figure 6The first clamping mechanism 200 includes a first lower clamping block 210, a first upper clamping block 220, a first lifting cylinder 230 and a first bracket 240. The first bracket 240 is arranged on the left side of the positioning platform 110, and the first bracket 240 can be slidably connected to the frame 100 in the left and right directions. The front and rear ends of the first lower clamping block 210 are rotatably connected to the first bracket 240. The cylinder body of the first lifting cylinder 230 is connected to the first lower clamping block 210, and the piston rod of the first lifting cylinder 230 is connected to the first upper clamping block 220. The gap between the first upper clamping block 220 and the first lower clamping block 210 is used for passing the excess plate on the left edge of the circuit board. The first lifting cylinder 230 is used to drive the first upper clamping block 220 to approach or move away from the first lower clamping block 210, so that the first upper clamping block 220 and the first lower clamping block 210 can clamp the excess plate on the left edge of the circuit board. The first lower clamping block 210 is connected to the output end of the first rotation drive mechanism 500. It can be understood that one of the output ends of the linear drive mechanism 400 is connected to the first bracket 240, and the linear drive mechanism 400 drives the first bracket 240 to approach the positioning platform 110, so that the excess plate on the left edge of the circuit board on the positioning platform 110 is passed between the first upper clamping block 220 and the first lower clamping block 210, and then the first lifting cylinder 230 drives the first upper clamping block 220 to approach the first lower clamping block 210, so that the first upper clamping block 220 and the first lower clamping block 210 clamp the excess plate on the left edge of the circuit board, and then the first rotary drive mechanism 500 drives the first lower clamping block 210 to rotate, and the first lower clamping block 210 drives the first lifting cylinder 230 and the first upper clamping block 220 to rotate. At this time, the first upper clamping block 220 and the first lower clamping block 210 drive the excess plate on the left edge of the circuit board to rotate, and the excess plate on the left edge of the circuit board can be broken off.

[0051] refer to Figure 6The second clamping mechanism 300 includes a second lower clamping block 310, a second upper clamping block 320, a second lifting cylinder 330 and a second bracket 340. The second bracket 340 is arranged on the right side of the positioning platform 110, and the second bracket 340 can be slidably connected to the frame 100 in the left and right directions. The front and rear ends of the second lower clamping block 310 are rotatably connected to the second bracket 340. The cylinder body of the second lifting cylinder 330 is connected to the second lower clamping block 310, and the piston rod of the second lifting cylinder 330 is connected to the second upper clamping block 320. The gap between the second upper clamping block 320 and the second lower clamping block 310 is used for passing the excess plate on the right edge of the circuit board. The second lifting cylinder 330 is used to drive the second upper clamping block 320 to move closer to or away from the second lower clamping block 310, so that the second upper clamping block 320 and the second lower clamping block 310 can clamp the excess plate on the right edge of the circuit board. The second lower clamping block 310 is connected to the output end of the second rotation drive mechanism 600. It can be understood that the other output end of the linear drive mechanism 400 is connected to the second bracket 340, and the linear drive mechanism 400 drives the second bracket 340 to approach the positioning platform 110, so that the excess plate on the right edge of the circuit board on the positioning platform 110 is passed between the second upper clamping block 320 and the second lower clamping block 310, and then the second lifting cylinder 330 drives the second upper clamping block 320 to approach the second lower clamping block 310, so that the second upper clamping block 320 and the second lower clamping block 310 clamp the excess plate on the right edge of the circuit board, and then the second rotary drive mechanism 600 drives the second lower clamping block 310 to rotate, and the second lower clamping block 310 drives the second lifting cylinder 330 and the second upper clamping block 320 to rotate. At this time, the second upper clamping block 320 and the second lower clamping block 310 drive the excess plate on the right edge of the circuit board to rotate, and the excess plate on the right edge of the circuit board can be broken off.

[0052] The rotation angle limiting device 900 includes two limiting turntables 910 and two limiting columns 920. Both limiting turntables 910 are provided with limiting arc grooves 911. Both limiting turntables 910 are rotatably connected to the frame 100. The two limiting turntables 910 are respectively connected to the first lower clamping block 210 and the second lower clamping block 310 for transmission, that is, the two limiting turntables 910 will respectively follow the first lower clamping block 210 and the second lower clamping block 310 for transmission connection. The two limiting columns 920 are both arranged on the frame 100. The upper ends of the two limiting columns 920 respectively extend into the limiting arc grooves 911 on the two limiting turntables 910, and the upper ends of the two limiting columns 920 are respectively used to abut against the side walls of the two limiting arc grooves 911. Here, the limiting function of a limiting post 920 is described. The upper end of the limiting post 920 extends into the limiting arc groove 911. When the limiting turntable 910 rotates along with the first lower clamping block 210 or the second lower clamping block 310, the limiting arc groove 911 rotates relative to the upper end of the limiting post 920. When the limiting turntable 910 rotates to a certain extent, the upper end of the limiting post 920 abuts against the side wall of the limiting arc groove 911. At this time, the limiting post 920 limits the rotation of the limiting turntable 910, that is, limits the rotation angle of the first lower clamping block 210 or the second lower clamping block 310, so that the first lower clamping block 210 and the second lower clamping block 310 can only rotate within a certain angle range. This prevents the first upper clamping block 220 and the second upper clamping block 320 from colliding with the circuit board due to excessive rotation angle of the first lower clamping block 210 and the second lower clamping block 310, thereby preventing damage to the circuit board. On the other hand, after the upper end of the limiting column 920 abuts against the side wall of the limiting arc groove 911, the limiting turntable 910 can stop rotating immediately, and the first lower clamping block 210 and the second lower clamping block 310 can stop rotating immediately and stabilize, so as to shape the next circuit board.

[0053] As another embodiment of the present invention, the limiting column 920 can also be replaced by a distance sensor, which detects the distance between the bottom wall of the limiting arc groove 911 and the limiting turntable 910 to determine the current rotation angle of the first lower clamping block 210 and the second lower clamping block 310, which will not be further elaborated here.

[0054] The first rotation driving mechanism 500 and the second rotation driving mechanism 600 may be a first motor and a second motor respectively, and the output ends of the first motor and the second motor are transmission-connected to the first lower clamping block 210 and the second lower clamping block 310 respectively.

[0055] refer to Figure 4 and Figure 6The circuit board shaping device also includes two pushing mechanisms 700, one of which is connected to the first lower clamping block 210, and the other is connected to the second lower clamping block 310. One of the pushing mechanisms 700 is used to push the excess plate on the left edge of the circuit board between the first upper clamping block 220 and the first lower clamping block 210, so that the excess plate on the left edge of the circuit board can fall from the gap between the first upper clamping block 220 and the first lower clamping block 210, and the other pushing mechanism 700 is used to push the excess plate on the right edge of the circuit board between the second upper clamping block 320 and the second lower clamping block 310, so that the excess plate on the right edge of the circuit board can fall from the gap between the second upper clamping block 320 and the second lower clamping block 310. It can be understood that after the first upper clamping block 220 and the first lower clamping block 210 break the excess plate on the left edge of the circuit board, and the second upper clamping block 320 and the second lower clamping block 310 break the excess plate on the right edge of the circuit board, the first lifting cylinder 230 drives the first upper clamping block 220 away from the first lower clamping block 210, and the second lifting cylinder 330 drives the second upper clamping block 320 away from the second lower clamping block 310, so that the first upper clamping block 220 and the first lower clamping block 210 release the excess plate on the left edge of the circuit board, and the second upper clamping block 320 and the second lower clamping block 310 release the excess plate on the right edge of the circuit board. Then, the two pushing mechanisms 700 push the excess sheet materials on the left and right edges of the circuit board toward the positioning platform 110 respectively, so that the excess sheet materials on the left edge of the circuit board fall from the gap between the first upper clamping block 220 and the first lower clamping block 210, and the excess sheet materials on the right edge of the circuit board fall from the gap between the second upper clamping block 320 and the second lower clamping block 310, so as to facilitate shaping of the next circuit board.

[0056] refer to Figure 6, the two pushing mechanisms 700 each include a push block 710 and a linear cylinder 720, wherein the cylinder body of one linear cylinder 720 is connected to the first lower clamping block 210, and one push block 710 is connected to the piston rod of one linear cylinder 720, and one linear cylinder 720 is used to drive one push block 710 toward or away from the positioning platform 110, so that one push block 710 can pass between the first upper clamping block 220 and the first lower clamping block 210, and move one push block 710 toward the positioning platform 110. The cylinder body of another linear cylinder 720 is connected to the second lower clamping block 310, and the other push block 710 is connected to the piston rod of another linear cylinder 720. The other linear cylinder 720 is used to drive the other push block 710 close to or away from the positioning table 110, so that the other push block 710 can be inserted between the second upper clamping block 320 and the second lower clamping block 310, and the other push block 710 pushes the excess plate on the right edge of the circuit board toward the positioning table 110. It can be understood that after the first upper clamping block 220 and the first lower clamping block 210 release the excess sheet material on the left edge of the circuit board, and the second upper clamping block 320 and the second lower clamping block 310 release the excess sheet material on the right edge of the circuit board, the two linear cylinders 720 respectively drive the two top blocks 710 to approach each other, so that one of the top blocks 710 is passed between the first upper clamping block 220 and the first lower clamping block 210 and pushes the remaining excess sheet material toward the positioning platform 110, and the other top block 710 is passed between the second upper clamping block 320 and the second lower clamping block 310 and pushes the remaining excess sheet material toward the positioning platform 110, thereby causing the remaining excess sheet material between the first lower clamping block 210 and the first upper clamping block 220 and between the second lower clamping block 310 and the second upper clamping block 320 to fall off, so that the next circuit board can be shaped.

[0057] refer to Figure 1 The circuit board shaping device further includes a conveyor belt 120 and a waste bin. The conveyor belt 120 is disposed on the frame 100. The right end of the conveyor belt 120 is disposed below the first lower clamping block 210 and the second lower clamping block 310 so that excess sheet material on the left and right edges of the circuit board can fall onto the conveyor belt 120. The left end of the conveyor belt 120 is disposed above the waste bin. The conveyor belt 120 is used to convey the excess sheet material on the left and right edges of the circuit board from right to left so that the excess sheet material on the left and right edges of the circuit board can fall into the waste bin. It is understood that the excess sheet material on the left and right edges of the circuit board that falls can fall onto the conveyor belt 120. The conveyor belt 120 then transports the excess sheet material from right to left so that the excess sheet material on the left and right edges of the circuit board can fall into the waste bin, thereby preventing the excess sheet material from affecting the normal operation of the circuit board shaping device. Specifically, a blanking hole (not shown) is provided on the frame so that the excess sheet material on the left and right edges of the circuit board can pass through the blanking hole and fall onto the conveyor belt 120.

[0058] In an embodiment of the present invention, after the excess plates on the left and right edges of the circuit board are broken off, the linear drive mechanism 400 drives the first bracket 240 and the second bracket 340 away from each other, and then the first lifting cylinder 230 and the second lifting cylinder 330 respectively drive the first upper clamping block 220 and the second upper clamping block 320 to rise, so that the first upper clamping block 220 and the second upper clamping block 320 can both loosen the broken excess plates, and then the two linear cylinders 720 are started, so that the two top blocks 710 can respectively retract the two excess plates, so that the two excess plates can fall onto the conveyor belt 120.

[0059] refer to Figure 4 and Figure 5 The circuit board shaping device also includes a clamping mechanism 800, which is mounted on the frame 100 and is used to secure the circuit board to the positioning platform 110. As will be appreciated, after the circuit board is placed on the positioning platform 110, the clamping mechanism 800 activates and secures the circuit board, preventing it from shaking during the process of breaking off the excess sheet material on the left and right edges, thereby improving the stability of the circuit board shaping process. After the circuit board shaping is completed, the clamping mechanism 800 releases the circuit board.

[0060] refer to Figure 5 The clamping mechanism 800 includes two clamping cylinders 810 and two clamping blocks 820. The cylinder bodies of the two clamping cylinders 810 are respectively located on the front and rear sides of the positioning platform 110. The two clamping blocks 820 are respectively connected to the piston rods of the two clamping cylinders 810. The two clamping cylinders 810 are used to drive the two clamping blocks 820 toward the positioning platform 110 so that the two clamping blocks 820 press against the middle of the circuit board. A soft pad 821 is provided on the clamping block 820, through which the clamping block 820 abuts against the middle of the circuit board.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
