Technical Field

[0001] This utility model relates to the field of fan circuit board processing technology, specifically to an easy-to-disassemble edge cutting machine for assembled circuit boards. Background Technology

[0002] A CPU fan, also known as a cooling fan, is a fan used to dissipate heat from the CPU. It's supplied to the heatsink and computer case, and works by quickly transferring heat from the CPU to the surrounding air, thus achieving a cooling effect. The effectiveness of this cooling is directly related to the quality of the CPU cooling fan and the heatsink itself.

[0003] The production and processing of computer CPU cooling fans requires the use of fan circuit boards. During production, the fan circuit board needs to be fixed on both sides to a carrier plate (similar to the integrated carrier plate used for assembling parts). The carrier plate and the fan circuit board together form a complete circuit board. In actual use, the user needs to manually remove the fan circuit board from the carrier plate to ensure the normal installation and use of the fan circuit board. However, the existing complete circuit boards have the problem of inconvenience in disassembling the fan circuit board. The disassembly process can easily damage the circuit board, affecting its normal use. To address this, this utility model proposes an easy-to-disassemble edge cutting machine that can easily cut the sides of the complete circuit board for easy disassembly. Utility Model Content

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-5 An embodiment of this utility model is provided: an easy-to-disassemble edge cutting machine for a fully assembled circuit board, including an upper platform 1. A guide groove 2 is provided inside the upper platform 1. A threaded screw 3 is rotatably installed in the guide groove 2 through a bearing. A servo motor 4 is fixedly installed on one side of the outer wall of the upper platform 1 by bolts. The output shaft of the servo motor 4 is fixedly connected to the threaded screw 3, so that the threaded screw 3 can be driven to perform forward and reverse rotation through the servo motor 4.

[0025] The threaded screw 3 is threadedly connected to a threaded seat 5. With this structural design, when the threaded screw 3 is rotating, the threaded seat 5 connected to it will move linearly left and right along the threaded screw 3. A lower plate 6 is fixedly installed on the lower surface of the threaded seat 5. Bearing seats 7 are fixedly installed on both sides of the lower surface of the lower plate 6. A rotating shaft 8 is rotatably installed between the two bearing seats 7. Cutting blades 9 are fixedly installed on both sides of the outer surface of the rotating shaft 8. One end of the rotating shaft 8 is fixedly connected to the output shaft of the rotary motor 10.

[0026] Based on the above structure, the rotary motor 10 can drive the rotating shaft 8 to rotate at high speed through its output shaft. The high-speed rotation of the rotating shaft 8 can drive the cutting blades 9 on both sides to rotate, thereby providing the necessary conditions for cutting the easy-to-remove edge through the high-speed rotating cutting blades 9.

[0027] The design of the double-sided cutting blade 9 allows for simultaneous cutting of the entire circuit board on both sides in a single cutting stroke, thus greatly improving the efficiency of cutting the easily detachable edges of the entire circuit board and increasing production speed.

[0028] Among them, side machine plates 11 are fixedly installed on both outer surfaces of the upper machine platform 1 by bolts, and a cross plate 12 is fixedly installed between the two side machine plates 11 and below the cutting blade 9.

[0029] In this embodiment, a material carrier 13 is fixedly installed at the center of the upper surface of the horizontal connecting plate 12. A support plate 19 is placed on the material carrier 13. In actual use, a fan circuit board is fixedly connected inside the support plate 19. Side limiting plates 14 are fixedly installed on both sides of the upper surface of the material carrier 13 by welding. Thus, the side limiting plates 14 can limit and block the left and right ends of the support plate 19, preventing the support plate 19 from moving in the left and right directions, and have a certain left and right limiting effect.

[0030] In this embodiment, in order to fix and clamp the side of the assembled circuit board, four threaded plates 15 are fixedly installed at the front and rear ends of the loading platform 13 and on the upper surface of the cross plate 12. Each threaded plate 15 is threaded with a threaded post 16.

[0031] Furthermore, a clamping plate 17 is mounted on the top of the threaded column 16 via a bearing, and a protective silicone pad is fixedly mounted on the outer contact surface of the clamping plate 17.

[0032] Each threaded post 16 has a knob 18 fixedly installed on the outer wall of the end away from the clamping plate 17, and the outer wall of the knob 18 is provided with anti-slip serrations.

[0033] This structural design allows the threaded column 16 to be manually rotated via the knob 18. As the threaded column 16 rotates, it extends and retracts on the threaded plate 15. When the threaded column 16 extends, the clamping plate 17 at its top abuts against the side of the column support plate 19. Thus, the four clamping plates 17 can respectively fix and clamp the front and rear ends of the support plate 19. By using the side limiting plate 14, the support plate 19 can be effectively fixed and limited, preventing it from moving during the cutting process, improving the cutting quality of the easy-to-remove edge and the yield rate of the cut product.

[0034] Working principle: In actual use, the carrier plate 19 carrying the fan circuit board is placed on the loading platform 13 (the carrier plate 19 carrying the fan circuit board is collectively referred to as the complete circuit board). Side limiting plates 14 are fixedly installed on both sides of the upper surface of the loading platform 13 by welding. The side limiting plates 14 can limit and block the left and right ends of the carrier plate 19, preventing the carrier plate 19 from moving in the left and right directions, and have a certain left and right limiting effect.

[0035] Meanwhile, threaded clamping structures are provided at both the front and rear ends of the loading platform 13. The threaded column 16 can be manually driven to rotate by the knob 18. When the threaded column 16 rotates, it will extend and retract on the threaded plate 15. When the threaded column 16 extends, the clamping plate 17 at its top can abut against the side of the column support plate 19. Thus, the front and rear ends of the support plate 19 can be fixed and clamped by the four clamping plates 17 respectively. By using the side limiting plate 14, the support plate 19 can be effectively fixed and limited to prevent it from moving during the cutting process, thereby improving the cutting quality of the easy-to-remove edge of the product and the cutting yield.

[0036] Once the support plate 19 is fixed, the rotary motor 10 can be put into operation. The rotary motor 10 can drive the rotating shaft 8 to rotate at high speed through its output shaft. The high-speed rotation of the rotating shaft 8 can drive the cutting blades 9 on both sides to rotate, thereby providing the necessary conditions for cutting the easy-to-remove edges through the high-speed rotating cutting blades 9.

[0037] During the high-speed rotation of the cutting blade 9, the servo motor 4 rotates synchronously. The servo motor 4 can drive the threaded screw 3 to rotate forward. When the threaded screw 3 rotates, the threaded seat 5 connected to it will move linearly from left to right along the threaded screw 3. The movement of the threaded seat 5 drives the two cutting blades 9 below to move. As the cutting blade 9 enters from the left side of the support plate 19 and exits from the right side, the high-speed rotating cutting blade 9 will cut a groove of a certain depth at the connection between the support plate 19 and the fan circuit board. The groove is used as an easy-to-remove edge. When it is necessary to disassemble the fan circuit board, the circuit board can be manually pried open. At this time, the easy-to-remove edge with a certain depth between the circuit board and the support plate 19 will break due to the external force, so that the fan circuit board can be removed from the support plate and peeled off, thus completing the easy-to-remove work of the circuit board.

[0038] For example, if the thickness of the connection between the support plate 19 and the fan circuit board is 1mm, an easy-to-remove edge groove with a depth of 0.8mm can be cut by designing the distance between the cutting blade 9 and the material carrier 13. Thus, the easy-to-remove edge can be broken by bending the support plate 19 or the circuit board, and then the circuit board can be peeled off from the support plate 19.

[0039] After the easy-to-remove edges of the assembled circuit board are cut, all structures are reset, and the staff can remove the cut and processed assembled circuit board.

[0040] Based on the above structure, the integrated circuit board cutting machine of this utility model can easily complete the detachable cutting work at the connection points on both sides of the integrated circuit board. After the cutting is completed, the detachable edge can be broken by manually bending it, thereby completing the disassembly of the fan circuit board carrier. It has a good detachable use effect, which can effectively avoid the damage caused by violent disassembly of the fan circuit board, ensure the normal disassembly and use of the circuit board, and has a fast and convenient bending disassembly and use effect.

[0041] Meanwhile, the cutting blade of this utility model is a double-sided cutting blade structure design. In actual use, it can complete the double-sided synchronous cutting of the entire circuit board in a single cutting stroke. It has the technical characteristics of double-sided synchronous cutting, which can greatly improve the cutting efficiency of the easy-to-disassemble edge of the entire circuit board and increase the production speed.

[0042] Furthermore, the support plate 19 can be effectively fixed and limited during the cutting process to prevent it from moving during the cutting process, thereby improving the cutting quality of the easy-to-disassemble edge and the yield of cut products. It has good usability and is suitable for widespread use.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
