Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB double-sided board technology, and more specifically, to a double-sided board rapid cutting device. Background Technology
[0002] A double-sided printed circuit board (PCB) is a common carrier for electronic components, featuring two working layers on each side that can be used for wiring and assembling electronic components. Compared to single-sided PCBs, double-sided PCBs offer higher wiring density and greater versatility.
[0003] Traditional PCB cutting equipment requires placing the PCB on a support platform and then cutting it from top to bottom with a cutter. Since multiple PCBs are typically printed and assembled onto a single substrate during production, the substrate needs to be fixed during cutting. However, because both sides of a double-sided PCB have circuitry printed on them, the circuitry on the bottom side may be deformed or damaged by the cutter during traditional cutting, affecting yield and work efficiency. Furthermore, the cut double-sided PCBs remain on top of the support platform, requiring manual or robotic pickup, which is cumbersome and requires further improvement. Utility Model Content

[0016] (1) This utility model is equipped with a first cutter and a second cutter. The first cutter is located at the top and the second cutter is located at the bottom. When cutting the double-sided panel, both ends of the double-sided panel substrate can be placed into the clamping seat and clamped by the clamping block.

[0026] According to an embodiment of the present invention, a double-sided panel rapid cutting device is provided.
[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a double-sided rapid cutting device according to an embodiment of the present invention includes a fixed rail 1 and a moving rail 2. Movable seats 3 are slidably connected to the inner sides of both the fixed rail 1 and the moving rail 2. A clamping seat 5 is fixedly installed on one end surface of each moving seat 3. A handle bolt 6 is threaded through the top surface of the clamping seat 5, and a clamping block 7 is fixedly installed on the bottom surface of the handle bolt 6. This is a common clamping structure. Fixed frames 9 are fixedly connected to both ends of the fixed rail 1, and moving frames 8 are fixedly connected to both ends of the moving rail 2. An electric telescopic rod 1 connects the moving frame 8 and the fixed frame 9. 4. A top frame 10 is fixedly installed on the top surface of the fixed rail 1, and a fixed support leg 22 is fixedly installed on the bottom surface of the fixed rail 1. A lower frame 15 is fixedly installed on the surface of the fixed support leg 22. A first electric cylinder 11 and a second electric cylinder 19 are fixedly installed on the top surface of the upper frame 10 and the bottom surface of the lower frame 15, respectively. A first lifting plate 12 and a second lifting plate 17 are fixedly installed on the other end of the moving rod of the first electric cylinder 11 and the second electric cylinder 19, respectively. A first cutter 13 and a second cutting blade 17 are fixedly installed on the other side surface of the first lifting plate 12 and the second lifting plate 17, respectively. The second cutting blade 18 and the second lifting plate 17 have an upper unloading port 20 on their inner side. A lower unloading port 21 is located directly below the upper unloading port 20 on the surface of the lower frame 15. The first cutting blade 13 is located above, and the second cutting blade 18 is located below. When cutting the double-sided panel, both ends of the double-sided panel substrate can be placed into the clamping seat 5 and clamped by the clamping block 7. The servo motor 25 drives the lead screw 4 to rotate, which in turn drives the moving seat 3 to move, thus moving the double-sided panel substrate to the double-sided panel. When the cutting area is aligned with the first cutter 13 and the second cutter 18, the first electric cylinder 11 and the second electric cylinder 19 are started simultaneously to cut the double-sided panel at the same time. At this time, the bottom surface of the double-sided panel is not under pressure, which avoids damage to the printed circuit on the bottom surface, improves the yield rate and improves work efficiency. At the same time, the cut double-sided panel falls through the upper unloading port 20 and the lower unloading port 21 onto the top surface of the conveyor 16 and is transported to the next process, saving the trouble of manual and mechanical picking and further improving work efficiency.
[0028] In one embodiment, the second cutter 18 is located directly below the first cutter 13, and the first cutter 13 is provided corresponding to the connection portion between the double-sided panel and the substrate, which facilitates alignment and cutting.
[0029] In one embodiment, the dimensions of the upper discharge port 20 and the lower discharge port 21 are both larger than the dimensions of the double-panel, and a conveyor 16 is installed below the lower discharge port 21 to facilitate material discharge and conveying.
[0030] In one embodiment, a servo motor 25 is fixedly installed at one end of both the fixed rail 1 and the moving rail 2, and a lead screw 4 is installed at the output end of the servo motor 25. The lead screw 4 passes through the moving seat 3 and is threadedly connected to the moving seat 3. The lead screw 4 is rotatably connected to the moving rail 2 and the fixed rail 1 through bearings, which is a common drive structure.
[0031] In one embodiment, a movable support leg 23 is fixedly installed on the bottom surface of the movable rail 2, and a movable wheel 24 is installed on the bottom surface of the movable support leg 23 to facilitate the movement of the movable rail 2.
[0032] In one embodiment, two sets of electric telescopic rods 14 are arranged, and both ends of the electric telescopic rods 14 are fixedly connected to the moving frame 8 and the fixed frame 9, respectively. When installing the double-sided panel substrate, the operator can insert one end of the double panel into the inner side of the moving seat 3 inside the fixed rail 1, rotate the handle bolt 6 located on one side of the fixed rail 1 to drive the clamping block 7 to clamp one end of the double-sided panel substrate. Then, start the electric telescopic rod 14 to retract, pull the moving rail 2 to move until the clamping seat 5 on one side of the moving rail 2 moves to the outside of the other end of the double-sided panel substrate. Then, the other end of the double-sided panel substrate can be fixed by the clamping block 7. The movement of the moving rail 2 can adapt to the use of double-sided panel substrates of different widths, which improves the convenience of use.
[0033] In one embodiment, guide rods are fixedly installed on one side surface of the first lifting plate 12 and the second lifting plate 17, and the guide rods pass through the upper frame 10 and the lower frame 15 respectively and are slidably connected to the upper frame 10 and the lower frame 15, thereby improving the stability of the lifting of the first lifting plate 12 and the second lifting plate 17.
[0034] Working principle: When cutting double-sided boards, both ends of the double-sided board substrate can be placed into the clamping seat 5 and clamped by the clamping block 7. The servo motor 25 drives the lead screw 4 to rotate, which in turn drives the moving seat 3 to move, thus moving the double-sided board substrate. When the double-sided board cutting area is aligned with the first cutter 13 and the second cutter 18, the first electric cylinder 11 and the second electric cylinder 19 are started simultaneously to cut the double-sided board simultaneously. At this time, the bottom surface of the double-sided board is not pressured, avoiding damage to the bottom printed circuit, improving the yield rate and work efficiency. At the same time, the cut double-sided board falls through the upper discharge port 20 and the lower discharge port 21 onto the top surface of the conveyor 16. The substrate is then transported to the next process, eliminating the hassle of manual and mechanical picking and further improving work efficiency. Simultaneously, during the installation of the double-sided substrate, the operator can insert one end of the double-sided substrate into the inner side of the moving seat 3 inside the fixed rail 1, and rotate the handle bolt 6 located on one side of the fixed rail 1 to drive the clamping block 7 to clamp one end of the double-sided substrate. Then, the electric telescopic rod 14 is retracted, pulling the moving rail 2 until the clamping seat 5 on one side of the moving rail 2 moves to the outside of the other end of the double-sided substrate. The clamping block 7 can then fix the other end of the double-sided substrate. The movement of the moving rail 2 adapts to double-sided substrates of different widths, improving ease of use.
