Description

Technical Field

[0001] The utility model relates to the field of circuit board processing, in particular to an edge and corner cutting device for integrated circuit boards. Background Art

[0002] An integrated circuit board is a carrier for carrying integrated circuits, but when we say integrated circuit board, we often also mean integrated circuit. Integrated circuit boards are mainly made of silicone, so they are generally green. When integrated circuit boards are produced in large quantities, residual glue will remain. The residual glue will be squeezed and condensed, and even extend to the outside of the circuit board to form scraps. The scraps need to be cut during the production of the circuit board.

[0003] When cutting the corners of a circuit board, the circuit board needs to be fixed. Conventional circuit board fixing devices are generally for circuit boards of a specific size and cannot fix circuit boards of other sizes. When the size of the circuit board changes, the fixing components of the circuit board often need to be replaced, which is rather troublesome. Therefore, a corner cutting device for an integrated circuit board is proposed to solve the above problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the embodiment, Figure 1-4 A corner cutting device for an integrated circuit board is provided. The utility model comprises a base 1, a support frame 2 is fixedly connected to the outer side of the base 1, an electric linear slide 3 is fixedly connected to the inside of the support frame 2, a mounting plate 4 is fixedly connected to the bottom of the slider of the electric linear slide 3, an electric push rod 5 is fixedly connected to the bottom of the mounting plate 4, a cutting device 6 is arranged at the bottom of the electric push rod 5, a moving device 7 is arranged inside the base 1, a protective box 8 located above the base 1 is fixedly connected to the top of the moving device 7, a clamping device 9 is arranged inside the protective box 8, two clamping plates 10 symmetrically distributed front and back are fixedly connected to the top of the clamping device 9, and two comparison rulers 11 are arranged inside the two clamping plates 10.

[0028] Among them, the moving device 7 includes a first motor 71 fixedly connected to the outside of the base 1, and the outside of the output shaft of the first motor 71 is fixedly connected to a reciprocating screw 72 rotatably connected to the inside of the base 1, and the outside of the reciprocating screw 72 is connected to a first transmission block 73 fixedly connected to the bottom of the protective box 8 through a threaded transmission.

[0029] In this embodiment, during actual use, the start of the first motor 71 drives the reciprocating screw 72 to rotate, and the first transmission block 73 moves under the action of the thread to change the position of the upper circuit board.

[0030] Among them, the base 1 is fixedly connected to the inside with a sliding rod 12, and the outer side of the sliding rod 12 is slidably connected to a sliding sleeve 13 fixedly connected to the first transmission block 73 through a connecting plate, and the top of the sliding sleeve 13 is fixedly connected to the bottom of the protective box 8.

[0031] In this embodiment, during actual use, the movement of the first transmission block 73 will also drive the sliding sleeve 13 fixed to the protective box 8 to slide outside the sliding rod 12. The sliding sliding sleeve 13, under the action of the connecting plate, keeps the first transmission block 73 stable and provides auxiliary support for the protective box 8.

[0032] Among them, the clamping device 9 includes a second motor 91 fixedly connected to the outside of the protective box 8, and the outside of the output shaft of the second motor 91 is fixedly connected to the left and right screw rods 92 that are rotatably connected to the inside of the protective box 8. The outsides of the left and right screw rods 92 are connected to two second transmission blocks 93 fixedly connected to the two clamps 10 respectively through threaded transmission.

[0033] In this embodiment, during actual use, the start of the second motor 91 will drive the left and right screw rods 92 to rotate, and cause the two second transmission blocks 93 to move in opposite directions, so that the two clamping plates 10 clamp and fix the circuit board placed therein.

[0034] The two clamping plates 10 are both U-shaped, and the opposite sides of the two clamping plates 10 are fixedly connected with buffer pads 14 .

[0035] In this embodiment, during actual use, the closing of the two clamping plates 10 will cause the two buffer pads 14 to contact the circuit board first, thereby preventing the circuit board from being crushed.

[0036] The two clamps 10 are provided with a sliding groove slidably connected to the comparison ruler 11, the four comparison rulers 11 are provided with a plurality of card slots, and the two clamps 10 are slidably connected with a card rod 15 that penetrates and extends to the outside of the card slot.

[0037] In this embodiment, during actual use, the comparison ruler 11 can be extended to different lengths by connecting the clamping rod 15 with different clamping slots. The width of the clamping plate 10 is smaller than the width of the circuit board. The extended comparison ruler 11 can be compared with the circuit board to determine the placement position of the circuit board.

[0038] Working principle:

[0039] First, place the circuit board between the two clamps 10, and determine the placement position of the circuit board by comparing it with the comparison ruler 11 on the edge, then start the second motor 91 to make the two clamps 10 clamp the circuit board, then start the first motor 71 to move the circuit board to the bottom of the cutting device 6, and start the electric push rod 5 and the cutting device 6 to cut the excess scraps of the circuit board. The cutting device 6 moves under the drive of the electric linear slide 3 to completely cut the circuit board. After cutting one side, it can continue to move by the first motor 71 so that the circuit board is located in the other direction of the cutting device 6 for cutting. The cut circuit board can be manually removed. If the model of the circuit board changes, it can be connected to different card slots on the comparison ruler 11 through the card rod 15 to change the extension length of the comparison ruler 11 for more convenient comparison.
