Description

Technical Field

[0001] The utility model relates to a circuit board processing device, in particular to a cutting device for processing double-sided multi-layer circuit boards, belonging to the technical field of circuit board processing devices. Background Art

[0002] A double-sided multi-layer circuit board has a dielectric layer in the middle and routing layers on both sides. A multi-layer board has multiple routing layers, and there is a dielectric layer between every two layers. The dielectric layer can be made very thin. A multi-layer circuit board has at least three conductive layers, two of which are on the outer surface, and the remaining layer is synthesized in the insulating board. The electrical connection between them is usually achieved through plated through holes on the cross section of the circuit board. In the production process of some double-sided multi-layer circuit boards, a cutting device is required to cut a whole circuit board into multiple parts.

[0003] However, when traditional cutting devices are used to cut double-sided multi-layer circuit boards, workers will hold the circuit boards in place and, after one section of cutting is completed, manually move the circuit boards to cut the next section. The handheld circuit boards are prone to tilting, and the distance of each movement may deviate, resulting in substandard shapes of the circuit boards after cutting and poor stability in use. Utility Model Content

[0004] The purpose of the present utility model is to provide a cutting device for processing double-sided multi-layer circuit boards in order to solve the above-mentioned problems. The cutting device can avoid the circuit board from being skewed when cutting the circuit board, and can ensure that the distance the circuit board moves each time is equal, thereby ensuring that the shape of the circuit board after cutting meets the standards and effectively improving the stability of use.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a cutting device for processing double-sided multi-layer circuit boards, comprising a base plate, a slide seat being slidably connected to the base plate, a support plate being fixedly connected to the top of the slide seat, a fixing structure being provided on the support plate, a locking structure being provided on the slide seat, and the locking structure comprising a slide rod and a stop block, a slide rod being slidably connected to the slide seat, a plurality of stop blocks being fixedly connected to the slide rod, a slot being provided on the slide seat with the same number as the stop blocks, a stop block being slidably connected to the base plate, one end of the stop block extending to the inside of one of the slots, and a reset spring being provided between the stop block and the base plate.

[0006] Preferably, the cross-section of the stop block is a trapezoidal structure, and the multiple stop blocks are linearly and equidistantly distributed.

[0007] Preferably, one end of the stopper cross section is a trapezoidal structure, and the other end of the stopper cross section is a trapezoidal structure.

[0008] Preferably, the cross-section of one end of the sliding rod is L-shaped, and a baffle is fixedly connected to the supporting plate.

[0009] Preferably, the fixing structure includes a second screw rod and a slider, the second screw rod is rotatably connected to the support plate, two sliders are threadedly connected to the second screw rod, the slider is slidably connected to the support plate, a splint is fixedly connected to the slider, and a plurality of openings are provided on the splint.

[0010] Preferably, two rotating rods are fixedly connected to both ends of the second screw rod, and the rotating rods pass through the second screw rod and are perpendicular to the second screw rod.

[0011] Preferably, the thread directions of the two ends of the second screw rod are opposite, and the distance between two adjacent openings is equal to the distance between two adjacent slots.

[0012] Preferably, a cutting structure is provided on the base plate, and the cutting structure includes a support seat and a first screw rod. The support seat is fixedly connected to the base plate, the first screw rod is rotatably connected to the support seat, the first screw rod is threadedly connected to a slide, and the slide is slidably connected to the support seat.

[0013] Preferably, a first motor is installed on the top end of one side of the support seat, and the output shaft of the first motor is fixedly connected to one end of the first screw rod.

[0014] Preferably, a rotating shaft is rotatably connected to the slide, a second motor is installed on the slide, a cutting wheel is installed at one end of the rotating shaft, and the other end of the rotating shaft is fixedly connected to the output shaft of the second motor.

[0015] The beneficial effects of the present invention are as follows: when the circuit board needs to be cut, the circuit board can be fixed by the fixing structure, and it can be cut when the fixing is completed. When a section of cutting is completed, the slide bar can be pushed, and the slide bar drives multiple blocks to move. The blocks will resist the movement of the stop blocks during the movement, and the reset spring will contract. As the stop blocks move, the end of the stop blocks will not contact the stop blocks, but one side of the stop blocks will contact the stop blocks. At this time, the slide seat can be pushed, and the slide seat will resist the inclined position of the end of the stop block during the movement. Under the resistance of the slide seat, the stop block will continue to move away from one of the slots until it is released from one of the slots. The slider is disengaged from the slot and then continues to push the slide. As the slider moves, the end of the stopper will face another slot. At this time, the return spring will extend to drive the stopper to engage with the other slot. At this time, the slider cannot be pushed. Since the distance between the two slots is equal to the width of the circuit board after cutting, when a section of the circuit board is cut, it is only necessary to push the slide to make the stopper fit into different slots in turn to achieve equidistant cutting of the circuit board. At the same time, fixing it through a fixed structure can also avoid skewed cutting, so that the shape of the circuit board after cutting can meet the standards, effectively improving the stability of use.

[0027] As a technical optimization solution of the utility model, Figure 1 and Figure 5 As shown, a cutting structure 2 is provided on the base plate 1, and the cutting structure 2 includes a support base 201 and a first screw rod 203. The base plate 1 is fixedly connected to the support base 201, and the first screw rod 203 is rotatably connected to the support base 201. The first screw rod 203 is threadedly connected to a slide 204, and the slide 204 is slidably connected to the support base 201. A first motor 202 is installed at the top of one side of the support base 201, and the output shaft of the first motor 202 is fixedly connected to one end of the first screw rod 203.

Then, the second screw rod 402 is rotated by the rotating rod 401, and the second screw rod 402 drives the two sliders 403 to move, and the sliders 403 drive the clamping plates 404 to move relative to each other. When the two clamping plates 404 are in contact with the two sides of the circuit board, the second screw rod 402 is stopped from rotating. At this time, the circuit board is fixed, and the first motor 202 can be started. The output shaft of the first motor 202 drives the first The screw rod 203 rotates, and the first screw rod 203 rotates the thread to drive the slide 204 to slide on the support seat 201.

At the same time, the two clamping plates 404 fix the circuit board to prevent the cutting from being skewed, so that the shape of the circuit board after cutting can meet the standard, effectively improving the stability of use.
