Description

Technical Field

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

[0002] PCB circuit board, also known as printed circuit board or printed circuit board, is a key electronic component. Its main function is to connect and support electronic components and realize electrical connection between electronic components. Single-sided and double-sided printed circuit boards are selectively processed by hole processing, chemical copper plating, electroplating copper, etching and other processing during manufacturing to obtain the required circuit graphics; the manufacturing of another type of multi-layer printed circuit board is also based on the inner core thin copper clad foil board as the base, and the conductive graphic layer and the semi-cured sheet are alternately laminated and bonded together at one time to form more than three layers of conductive graphic layer interconnection, which has the three functions of conduction, insulation and support.

[0003] Before or after completing the hole opening operation, the circuit board needs to be cut so that the circuit board can meet the production size requirements. For example, a Chinese patent (publication number: CN211930989U) discloses a PCB board cutting device, which mainly solves the problem that the existing PCB board cutting method is manual marking and cutting, and the cutting speed is slow.

[0004] Although the above patent solves the problem of slow cutting speed, it still has the following disadvantages in actual operation. In the prior art, since the positions of the cutting die and the upper punch are fixed, the cutting position of the PCB board cannot be adjusted during the cutting process. Secondly, since the inner diameter of the PCB board placement seat cannot be adjusted, the size of the PCB board that can be placed is limited, thereby reducing the practicality of the existing PCB board cutting device.

[0005] Secondly, a cutting device for a PCB substrate, such as a Chinese patent (publication number: CN220094803U), can cut PCB boards of different sizes during operation, but the cutting device will vibrate during the cutting process, so that the PCB will also vibrate synchronously. The supporting fixture in the patent is an "X"-shaped structure composed of multiple rods intersecting and combining. This results in that during the cutting process, the vibration of the cutting device will be transmitted to the "X" structure, and the "X"-shaped structure is in a rotational connection, which will cause the entire device to vibrate, thereby causing the PCB board to vibrate, which will cause the PCB board to be easily damaged during the cutting process. In addition, the following situation will occur during the use of the above patent: the "X"-shaped structure on one side suddenly changes, causing the "X" combination structure on one side to become longer, thereby causing the PCB circuit board to be displaced, thereby causing the cutting failure.

[0037] PCB circuit board, also known as printed circuit board or printed circuit board, is a key electronic component. Before or after completing the hole opening operation, the circuit board needs to be cut so that the circuit board can meet the production size requirements. The structure of the device is as follows: it includes a frame seat 1, the frame seat 1 can be regarded as a U-shaped structure, the inner bottom surface of the frame seat 1 is provided with a U-shaped groove 11, and a first screw 2 is rotatably installed inside the U-shaped groove 11, and a support rod 21 is rotatably installed on the circumferential surface of the first screw 2, and the lower end of the support rod 21 is located inside the U-shaped groove 11, and the upper end is located outside the U-shaped groove 11. Secondly, a cutting motor 3 is fixedly installed on the upper right end of the support rod 21; the right end of the first screw 2 is located outside the frame seat 1. Secondly, convex slide grooves 12 are provided on both sides of the upper part of the frame seat 1, and a first slide groove 13 with an opening facing downward is provided on the inner upper end surface of the frame seat 1.

[0038] Secondly, a worm 4 is rotatably mounted on the upper end of the frame seat 1, and the front end of the worm 4 is located on the outer side of the frame seat 1. A symmetrical first L-shaped rod 8 is fixedly mounted on both sides of the upper rear end of the frame seat 1, and then a second L-shaped rod 9 is slidably mounted inside the convex slide groove 12 at the upper front end of the frame seat 1; two second slide rods 91 are fixedly mounted on the lower end of the second L-shaped rod 9, and two movable slides 6 are horizontally slidably mounted on the circumferential surface of the second slide rod 91, wherein a connecting rod 55 is rotatably mounted on the upper end of the movable slide 6, and the connecting rod One end of 55 away from the movable slide 6 is rotatably mounted on the outer circumferential surface of the movable ring 54, and a second screw 53 is rotatably mounted inside the movable ring 54, a worm gear 5 is fixedly mounted on the top of the second screw 53, and a connecting column 51 is rotatably mounted on the top of the worm gear 5, a limiting column 52 is fixedly mounted on the top of the connecting column 51, and the limiting column 52 is slidably mounted inside the first slide groove 13, so that when the second L-shaped rod 9 slides, the limiting column 52 can move synchronously, thereby preventing the second L-shaped rod 9 from being unable to move.

[0039] The same structure is also fixedly installed inside the first L-shaped rod 8, but the connecting column 51 inside the two first L-shaped rods 8 is directly fixedly installed on the inner upper end of the frame seat 1, so the first L-shaped rod 8 does not move at all, and the internal connecting column 51 is fixedly installed on the inner upper end of the frame seat 1.

[0040] Then, a cavity 61 is opened from the lower end to the inside of the movable slide 6, and then through holes 62 are opened on both sides of the movable slide 6, the through holes 62 are connected with the cavity 61, and the side length of the through holes 62 is smaller than the cavity 61, and then a straight plate 7 is installed inside the cavity 61, and the two ends of the straight plate 7 pass through the through holes 62 and are located on the outside of the movable slide 6, and secondly, a frame rectangle 71 is fixedly installed on the outside of the straight plate 7, and a movable frame 72 is slidably installed on the outside of the straight plate 7, and a spring 73 is fixedly installed between the movable frame 72 and the frame rectangle 71, wherein the ends of the frame rectangle 71 and the movable frame 72 that are away from each other are fitted together with the inner wall of the cavity 61, and then, an upper plate 63 is fixedly installed on the adjacent end of the movable slide 6, and the upper plate 63 is located above the straight plate 7.

[0041] When in use, the staff slides the second L-shaped rod 9, and the second L-shaped rod 9 brings the second sliding rod 91 and the moving slide 6 to slide synchronously, so as to reduce or increase the distance between the first L-shaped rod 8 and the first L-shaped rod 8. After the adjustment is completed, the worm 4 is rotated. The worm 4 will drive the worm wheel 5 to rotate during the rotation, and the second screw 53 will be rotated synchronously during the rotation of the worm wheel 5, so that the moving ring 54 on the circumferential surface of the second screw 53 can move up and down, and in the process of the moving ring 54 moving downward, the connecting rod 55 on the circumferential surface will be rotated in the opposite direction, so that the connecting rod 55 can push the moving slide 6 to gradually move away, thereby increasing the distance between the two moving slides 6; secondly, in the process of the moving ring 54 moving upward, the moving ring 54 will also make the connecting rod 55 rotate in the opposite direction, but the connecting rod 55 will make the moving slide 6 gradually approach during the rotation, so as to reduce the distance between the moving slides 6. With the cooperation of the above structure, the equipment can limit PCB circuit boards of different sizes, and then when the movable slide 6 moves to a suitable position, the operator only needs to place the four corners of the PCB circuit board on the upper end of the straight plate 7 respectively, and then the operator presses the end of the horizontal straight plate 7 away from each other with a finger to allow the spring 73 to contract. At this time, the operator can slide the symmetrical straight plates 7 upward to fix the corners of the PCB circuit board, and then follow the above steps to perform synchronous operations, and then start the cutting motor 3. At this time, the operator rotates the first screw 2. When the first screw 2 rotates, the support rod 21 can reciprocate horizontally and linearly, so that the support rod 21 can move synchronously with the cutting motor 3, and then the cutting motor 3 can cut the PCB circuit board during the movement. After the cutting is completed, the above operation can be repeated; during the use of this device, with the cooperation of the above structure, PCB circuit boards of different sizes can be cut and trimmed, so as to meet the needs of the factory, and the device can be applicable to PCB boards of various sizes, so that the factory reduces the cost of the cutting device during the purchase process.

[0042] Specifically, Figures 1 to 5As shown, a connecting column 51 is rotatably installed on the upper end of the worm wheel 5, wherein the upper end of one of the connecting columns 51 is fixedly installed on the inner upper end of the frame seat 1, and the upper end of the other connecting column 51 is fixedly connected to a limiting column 52, and the limiting column 52 is slidably installed inside the first slide groove 13; a worm 4 is rotatably installed inside the upper end of the frame seat 1, and the right end of the worm 4 is located on the outer side of the frame seat 1, and the worm 4 is meshed with the worm wheel 5; an upper plate 63 is fixedly installed on the adjacent end of the movable slide 6, a cavity 61 is opened from the lower end of the movable slide 6 to the inside, and through openings 62 are opened on both sides of the movable slide 6, and a straight plate 7 is slidably installed inside the movable slide 6, and the two ends of the straight plate 7 pass through the through openings 62 and are located on the outer side of the movable slide 6; a frame rectangle 71 is fixedly installed on the outer side of the straight plate 7 and a movable frame 72 is slidably installed, a spring 73 is fixedly installed between the frame rectangle 71 and the movable frame 72, and the end of the frame rectangle 71 away from the movable frame 72 is in contact with the inner wall of the cavity 61.

[0043] The cutting devices on the market all need to fix the PCB circuit board during operation, so that the PCB will not shift during the cutting process; and some devices will inevitably shake during use; during the use of this device, the corners of the PCB circuit board are fixed between the straight plate 7 and the upper plate 63 respectively. During the operation of the cutting motor 3, the PCB circuit board will be transmitted to the movable slide 6 during the vibration process, and the movable slide 6 cannot move under the restriction of the connecting rod 55. Therefore, the movable slide 6 can only remain in a fixed state, thereby enabling the movable slide 6 to restrict the PCB circuit board. The PCB circuit board will not vibrate or float up and down during the cutting process, thereby ensuring that the PCB circuit board can be in a relatively stable state during the cutting process, avoiding damage to the PCB.

[0044] Working principle: First, slide the second L-shaped rod 9, and the second L-shaped rod 9 brings the second sliding rod 91 and the second screw rod 53 closer to or away from the first L-shaped rod 8.

[0045] Then the worm 4 is rotated, and the worm 4 drives the worm wheel 5 to rotate, so that the second screw 53 rotates synchronously, so that the moving ring 54 moves downward or upward, so that the connecting rod 55 pushes the moving slide 6 to slide on the circumferential surface of the second slide bar 91 and the first slide bar 81.

[0046] Then, the corner of the PCB circuit board is placed on the upper end surface of the straight plate 7, and then the outer side of the straight plate 7 is pressed so that the straight plate 7 can move upward, thereby fixing the corner of the PCB circuit board.

[0047] Then the cutting motor 3 is started, the first screw rod 2 is rotated, and the cutting motor 3 is made to move horizontally, so as to complete the cutting operation.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
