[0001] This utility model relates to the technical field of circuit board production equipment, and in particular to a cutting device for circuit board production. Background Technology

[0002] Printed circuit boards (PCBs) are one of the most important components in the electronics industry. Almost every electronic device, from small items like electronic watches and calculators to large systems like computers, communication devices, and military weapons, uses PCBs to enable electrical interconnection between integrated circuits and other electronic components. A PCB consists of an insulating substrate, connecting wires, and pads for mounting and soldering electronic components, serving the dual function of conductive lines and an insulating substrate.

[0003] The production process of circuit boards requires cutting. However, currently, after a section is cut, the circuit board needs to be manually fixed again before cutting again, which is inefficient. Furthermore, the circuit board is only fixed on the outside during cutting, resulting in poor stress distribution at the cutting point and affecting the cutting quality.

[0004] Therefore, a cutting device for circuit board production is proposed. Utility Model Content

[0005] (a) Technical problems to be solved To overcome the shortcomings of existing technologies, a cutting device for circuit board production is proposed to solve the problems of low efficiency and poor cutting force affecting cutting quality in the current circuit board cutting process.

[0006] (II) Technical Solution This utility model is achieved through the following technical solution: This utility model proposes a cutting device for circuit board production, including a bottom frame with an open top, a controller installed on the outside of the bottom frame, a screening plate covering the upper end of the bottom frame, a moving plate installed at the upper end of the bottom frame via a left and right drive mechanism, side extension blocks on both sides of the moving plate, a cutting groove penetrating vertically on one side of the moving plate, a moving frame installed upward on the side of the moving plate, a lifting frame with an internal downward opening installed inside the moving frame, a second electric push rod installed at the top of the moving frame and connected to the lifting frame, a third electric push rod installed at the upper end of the lifting frame via a front and rear drive mechanism, a fixed box connected to the output end of the third electric push rod, a second motor installed inside the fixed box, and a cutting blade connected to the output end of the second motor.

A first electric push rod is installed on the upper end of the side plate frame, and the output end of the first electric push rod passes through the side plate frame and is connected to a lower pressure plate.

[0008] Furthermore, the bottom frame has a removable storage box installed inside.

[0009] Furthermore, the left and right drive mechanism includes a positioning slide rod located on one side of the bottom frame and a first lead screw rotatably mounted on the other side via a bearing. The side extension block has positioning slide holes and a second threaded hole on both sides for easy installation, which are respectively connected to the positioning slide rod and the first lead screw. A first motor is installed on the outside of the bottom frame and connected to the first lead screw.

[0010] Furthermore, both the side panel frame and the top of the movable frame are equipped with stabilizing telescopic rods that are respectively connected to the lower pressure plate and the lifting frame.

[0011] Furthermore, both the lower pressure plate and the bottom surface of the lifting frame are provided with a buffer layer.

[0012] Furthermore, the front and rear drive mechanism includes a second lead screw rotatably mounted on the upper end of the lifting frame, a third motor mounted on the outside of the lifting frame and connected to the second lead screw, a movable slider mounted on the upper end inside the lifting frame, and a first threaded hole inside the movable slider connected to the second lead screw, a third electric push rod mounted on the lower end of the movable slider, and a limiting frame with an opening located outside the movable slider inside the lifting frame enclosing it.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model has the following advantages: 1.

[0014] 2. In this utility model, the second electric push rod pushes the lifting frame downward to clamp the circuit board together with the upper part of the moving plate. This ensures that both sides of the cutting area are clamped and fixed during cutting, avoiding uneven force on the circuit board when cutting, and reducing the impact on cutting quality.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] Please see Figures 1-4This utility model provides a cutting device for circuit board production, including a bottom frame 1 with an open top to make the bottom more stable and better under stress during processing. A controller 3 is installed on the outside of the bottom frame 1, which facilitates the operation of the electrical components in the device by the operator, making the work more convenient. A screening plate 4 is covered on the upper end of the bottom frame 1 to facilitate the downward fall of debris, and the screening plate 4 can support and slide the moving plate 12. A removable storage box 2 is installed inside the bottom frame 1 to collect the downward-falling debris, making cleaning faster. The moving plate 12 is installed at the upper end of the bottom frame 1 through a left and right drive mechanism to support the cutting area during cutting and strengthen the stress. To enhance the force distribution, the movable plate 12 has side extension blocks 117 on both sides for bearing. The left and right drive mechanism includes a positioning slide rod 119 on one side of the bottom frame 1 and a first lead screw 6 rotatably mounted on the other side via bearings. Positioning slide holes 120 and second threaded holes 118 are conveniently installed on both sides of the side extension blocks 117, connecting to the positioning slide rod 119 and the first lead screw 6 respectively. A first motor 7 is installed on the outside of the bottom frame 1, connected to the first lead screw 6. The first motor 7 drives the first lead screw 6 to rotate, passing through the second threaded hole 118 to move the movable plate 12. This allows the upper cutting blade 114 to move left and right to adjust its position, and the positioning slide rod 119 and positioning slide holes 120 enhance the stability and support of the sides. This design makes it easier to move the movable plate 12. The movable plate 12 has a through-cutting groove 13 on one side, allowing the cutting blade 114 to cut internally, and the resulting debris can fall downwards. A movable frame 15 is mounted upwards on the side of the movable plate 12 to facilitate the movement of the lower lifting frame 11. The movable frame 15 has a downward-opening lifting frame 11 inside, and a transparent observation window can be installed on the outside of the lifting frame 11 for easy observation of the internal situation. A second electric push rod 16 is mounted at the top of the movable frame 15 and connects to the lifting frame 11. Driven by the second electric push rod 16, the lifting frame 11 can move up and down to clamp the circuit board during cutting, resulting in better fixation during circuit board cutting. To reduce offset, a third electric push rod 111 is mounted on the upper part of the lifting frame 11 via a front and rear drive mechanism. The front and rear drive mechanism includes a second lead screw 17 rotatably mounted on the upper part of the lifting frame 11. A third motor 116 is mounted on the outside of the lifting frame 11 and connected to the second lead screw 17. A movable slider 18 is mounted on the upper part of the lifting frame 11, and the movable slider 18 has a first threaded hole 19 inside that connects to the second lead screw 17. The third electric push rod 111 is mounted on the lower end of the movable slider 18. A limiting frame 110 with an opening on the outside of the movable slider 18 is placed inside the lifting frame 11 to enclose it. The sliding action between the limiting frame 110 and the movable slider 18 prevents it from tipping over during movement, resulting in better movement stability.The third motor 116 drives the second lead screw 17 to rotate, causing the sliding block 18, which passes through the first threaded hole 19, to move the lower cutting blade 114 back and forth to cut the circuit board. This, combined with the left-right movement at the upper end, allows for cutting at different locations on the circuit board, resulting in better movement, reduced manual adjustments, and higher work efficiency. The output end of the third electric push rod 111 is connected to a fixed box 112, inside which a second motor 113 is installed. When the third electric push rod 111 moves the fixed box 112 up and down, the cutting blade 114 moves up and down to cut the circuit board, resulting in better cutting. The output end of the second motor 113 is connected to the cutting blade 114, which rotates to cut the circuit board.

[0019] The bottom frame 1 has side plate frames 5 installed on both sides for fixation. The inner side of the side plate frame 5 is provided with a placement plate 8 that is horizontal with the moving plate 12. When the circuit board is placed on the upper end of the placement plate 8, its bottom end surface also contacts the lower end surface of the moving plate 12, which can enhance the support effect of the circuit board and avoid the instability of the cutting force during placement. The upper end of the side plate frame 5 is provided with a first electric push rod 9, and the output end of the first electric push rod 9 passes through the side plate frame 5 and is connected to the lower pressure plate 10. By pushing the lower pressure plate 10 downward by the first electric push rod 9, one side of the circuit board can be pressed tightly, which can prevent the circuit board from shifting under force during cutting and movement. The top of the side plate frame 5 and the moving frame 15 are both provided with a stabilizing telescopic rod 115, which is connected to the lower pressure plate 10 and the lifting frame 11 respectively. The stability is enhanced by the stabilizing telescopic rod 115, which makes the up-and-down movement more stable. The bottom end surface of the lower pressure plate 10 and the lifting frame 11 are provided with a buffer layer 14 to reduce the excessive force when pressing and fixing the circuit board.

[0020] Working principle: In use, first connect the first motor 7, first electric push rod 9, second electric push rod 16, third electric push rod 111, second motor 113, and third motor 116 to the controller 3, and connect them to an external power supply. During operation, one side of the circuit board is placed on the upper end of the placement plate 8 through the middle of the lifting frame 11 and the moving plate 12. Under the push of the first electric push rod 9, the pressure plate 10 presses down to clamp one side of the circuit board. During cutting, according to the position to be cut, the first motor 7 drives the first lead screw 6 to rotate, causing the lifting frame 11 and the moving plate 12 to move through the second threaded hole 118, thereby adjusting the position. The cutting blade 114 is positioned so that it is at the point on the circuit board to be cut. Then, the second electric push rod 16 pushes the lifting frame 11 downward to clamp the cutting point of the circuit board. The third electric push rod 111 pushes the fixing box 112 downward so that the cutting blade 114 contacts the circuit board. The second motor 113 then drives it to perform the cutting process. Afterward, the third motor 116 drives the second lead screw 17 to rotate, causing the moving slider 18 to move the lower cutting blade 114 back and forth to perform the cutting process. After cutting, the operator can remove the cut circuit board and repeat the above steps to complete the work.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
