Description

Technical Field

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

[0002] The processing and cutting of circuit boards is a key step in the electronics manufacturing process, and its precision and efficiency directly affect product quality and cost. Currently, the main circuit board processing and cutting processes include mechanical shearing, stamping, tool cutting, drilling cutting, and laser cutting. During the production process, some circuit boards are produced in smaller sizes, so they are processed on a whole circuit board, thereby processing several small circuit boards. Each group is grouped into a column, and a gap is left between the two adjacent circuit boards in each group during processing. The space between each adjacent column of circuit boards is used to connect the two adjacent columns of circuit boards, facilitating overall transportation. After the processing of several smaller circuit boards is completed, the entire circuit board is cut in the final step to separate each individual circuit board.

[0003] In the prior art, during the cutting process, a certain width of original sheet material is generally left between two adjacent rows of circuit boards. This is used to maintain the stability of the connection between the two adjacent rows of circuit boards while more clearly distinguishing the individual circuit boards. At the same time, it is prevented that the cut portion during cutting affects the processed portion of the circuit board, thereby causing the processed portion of the circuit board to be damaged due to cutting. Therefore, a portion of connection spacing area is left between the two adjacent rows of circuit boards, and the spacing area needs to be cut out during cutting. This will result in the need to distinguish the connection spacing area from the circuit board again after cutting, thereby increasing the time required for circuit board processing and reducing the efficiency of circuit board cutting.

DETAILED DESCRIPTION

[0023] The present application will be further described in detail below with reference to the drawings.

[0024] Example:

[0025] Reference Figures 1-4 The utility model discloses a cutting device for a circuit board processing process, comprising a workbench 1, a dense circuit board 2 and a bracket 3. The bracket 3 is fixedly mounted on the end side of the workbench 1. A rectangular groove 4 is provided at one end of the top side of the workbench 1 close to the bracket 3. A slide groove 5 is provided on both sides of the top side of the workbench 1 located at the rectangular groove 4. A slide 6 is slidably connected in the slide groove 5. Threaded rods 7 are rotatably connected on both sides of the bracket 3. The ends of the threaded rods 7 are inserted into the slide 6. The threaded rods 7 are threadedly connected to the slide 6. A cutting piece 8 is provided on the bracket 3, and a positioning piece 9 is provided on the inner side of the bracket 3.

[0026] In this embodiment, an intermittent conveyor can be provided on the workbench 1 during use to facilitate the transportation and stopping of the dense circuit board 2. Before cutting, the threaded rod 7 is first rotated so that the two sides of the dense circuit board 2 can be supported by the slide plate 6. The adjustment portion can be adapted to dense circuit boards 2 of different widths. When the cutting member 8 is used for cutting, the position where the dense circuit board 2 is cut is above the rectangular groove 4. During the initial cutting, the connection spacer in the dense circuit board 2 needs to be cut first. After the cutting is completed, the connection spacer is not cut out in the middle or other positions, so that the connection spacer is still supported by the slide plates 6 at both ends after being cut.

[0027] After the connection spacer is cut, one of the columns on the dense circuit board 2 will be cut. After the cutting is completed, the single circuit boards on the dense circuit board 2 will be separated. At this time, each single circuit board will lose the support of the connection spacer and the support of the slide 6. At this time, the single circuit board will fall from the rectangular groove 4. When the dense circuit board 2 is supported by the slide 6, the support area at both ends is less than one-third of the length of the single circuit board. Therefore, after cutting, the single circuit board located on the side can fall into the rectangular groove 4, and the connection spacer can be supported. Therefore, the single circuit board and the connection spacer can be distinguished after the cutting is completed, thereby eliminating the subsequent distinction work and improving the efficiency of circuit board processing.

The outer peripheral wall of the screw shaft 11 is threadedly connected to a screw nut 13.

[0029] In this embodiment, the driving motor 10 is arranged to drive the rotation of the screw shaft 11, thereby driving the movement of the screw nut 13 in the empty slot 12, so that stable translation cutting can be realized during cutting, and the stability during cutting of the dense circuit board 2 is improved.

[0030] In further preferable embodiments of the utility model, as shown in Figure 3 The support plate 14 is slidably connected in the empty slot 12, the top side of the support plate 14 is fixedly connected with the screw nut 13, the bottom side of the support plate 14 is fixedly connected with the bearing column 15, the side bottom of the bearing column 15 is fixedly connected with the cutting motor 16, the bottom of the bearing column 15 away from the side of the cutting motor 16 is provided with the cutting knife 17, and the cutting knife 17 is connected with the output end of the driving motor 10.

[0031] In this embodiment, when the driving motor 10 drives the rotation of the screw shaft 11, the screw nut 13 will be moved, the support plate 14 will be moved, the bearing column 15 will be moved, the cutting motor 16 and the cutting knife 17 will be moved, the cutting motor 16 drives the rotation of the cutting knife 17, and the dense circuit board 2 can be cut.

[0032] In further preferable embodiments of the utility model, as shown in Figure 3 The positioning piece 9 comprises a mounting frame 18, the mounting frame 18 is fixedly installed between the two side walls in the support 3, the mounting frame 18 is in the shape of a Chinese character 'n', the top side of the mounting frame 18 is fixedly connected with the electric telescopic joint 19, the telescopic end of the electric telescopic joint 19 extends to the upper side of the dense circuit board 2 through the top side of the mounting frame 18, and the telescopic end of the electric telescopic joint 19 is connected with the positioning plate 20.

[0033] In this embodiment, the mounting frame 18 is arranged between the two inner side walls of the support 3, so that the movement of the dense circuit board 2 is not blocked, and when the electric telescopic joint 19 is arranged and the dense circuit board 2 moves to a suitable position, the electric telescopic joint 19 drives the positioning plate 20 to descend, so that the dense circuit board 2 is positioned, and then the cutting piece 8 can cut.

[0034] In further preferable embodiments of the utility model, as shown in Figure 1-2 The top side of one end of the two slide plates 6 close to each other is inclined, the end of the workbench 1 close to the support 3 is inclined, and the end of the workbench 1 close to the support 3 is fixedly connected with the storage box 21.

The end of the workbench 1 close to the bracket 3 is tilted, so that after the connection interval area is cut, it can slide into the storage box 21 for storage under the push of the dense circuit board 2 behind. After the single circuit board falls into the rectangular groove 4, a conveyor belt can be set under the rectangular groove 4 for transportation.
