Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment, in particular to a cutting machine. Background Art

[0002] Silicone gasket is a new type of thermal conductive interface material used to fill the gap between the surface of microelectronic materials and the radiator, remove the air in it, and establish an effective heat conduction channel between the electronic components and the radiator. It can greatly reduce the contact thermal resistance, enable the radiator to play its full role, and improve the thermal conductivity efficiency.

[0003] Silicone gaskets are soft and sticky on the surface, so they tend to stick to the cutter and its accessories. Therefore, manual cutting is often required, or the machine is combined with manual adjustment of the direction of the silicone gasket to adjust the cutting angle, which requires a lot of manual labor. Utility Model Content

[0004] In order to overcome the above shortcomings, the purpose of the present invention is to provide a cutting machine to solve the problem of manual adjustment required during the cutting process of the silicone gasket proposed in the above background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is a cutting machine, comprising:

[0006] The machine has a transmission line on the top, which extends along a first direction and is used to transport the silicone gasket.

[0007] A cutting device is disposed on one side of the transmission line along the second direction and includes a drive assembly and a cutter assembly. The cutter assembly includes a cutter box, which is disposed above the transmission line. The drive assembly is connected to the cutter box and is configured to move the cutter box up and down relative to the transmission line along a third direction. The cutter box has an open bottom and contains multiple cutters. Each cutter extends along the third direction and is configured to be pressed downward by the drive assembly to cut the silicone gasket. The first, second, and third directions are mutually perpendicular.

[0008] The cutter assembly further includes a stopper plate disposed on top of the transmission line and corresponding to the cutter box. The stopper plate extends along the first direction and includes a predetermined cutting channel, which is corresponding to the plurality of cutters and is used to prevent the silicone gasket from moving with the plurality of cutters.

[0009] The utility model provides a cutting box that is pressed down along a third side, and multiple cutting knives arranged inside the cutting box cut the silicone gasket. Through the design of a preset cutting channel, it can ensure that the contact between the cutting knife and the silicone gasket is more precise, reduce cutting errors, improve product consistency and quality, and at the same time avoid the silicone gasket from moving up with the cutting knife after cutting due to its own adhesion.

[0010] In some embodiments, the driving assembly includes a first guide post, a second guide post, and a connecting plate, wherein the first guide post and the second guide post are arranged in parallel along the third direction, and the connecting plate connects the tops of the first guide post and the second guide post respectively.

The lifting motor is disposed on a side of the fixed block facing the transmission line along the second direction and includes a lifting connection end, the bottom of which is connected to the top of the cutter box.

[0012] With this technical solution, the fixed block is inserted through the first and second guide posts, making the cutting machine more stable during the cutting process and reducing errors caused by mechanical vibration or impact. The rapid response of the lifting motor improves cutting efficiency, making the cutting machine more efficient. The integrated design of the fixed block and lifting motor reduces the number of connecting cables, which helps improve system reliability and reduce the impact of external interference on the system, thereby reducing maintenance costs.

[0013] In some embodiments, the drive assembly further includes an adjustment assembly comprising a knob and a screw. The screw extends along the third direction and is disposed between the first guide post and the second guide post. One end of the screw is connected to the fixed block, and the other end is disposed through the connection and rotatably connected to the knob, such that rotation of the knob drives the fixed block to move up and down relative to the first guide post and the second guide post along the third direction.

[0014] With the above technical solution, the design of the knob allows the operator to adjust the height or position of the cutter box by a simple rotation action, thereby improving the convenience of operation.

The transfer roller is located between the unwinding roller and the first pressure roller, and is used to allow the protective film to circulate through the transfer roller and be pressed against the surface of the silicone gasket by the first and second pressure rollers.

[0017] The above technical solution, through the design of the unwinding roller, first pressure roller, and second pressure roller, allows for precise control of the protective film's tension, maintaining its stability during the cutting process and preventing subsequent cutting errors caused by uneven tension. The transfer roller design allows the protective film to circulate across it and be pressed against the silicone gasket surface by the first and second pressure rollers, helping to improve the bond between the protective film and the silicone gasket, ensuring a clean, bubble-free edge on the cut product.

[0018] In some embodiments, the winding assembly includes a second frame, a winding roller, and a drive motor. The second frame is disposed on one side of the first frame along the first direction. The winding roller is disposed on the top of the second frame on the side facing the transmission line and is used to wind up the waste protective film that has circulated through the transfer roller. The drive motor is disposed on the other side of the second frame corresponding to the winding roller and is used to drive the winding roller to rotate and rewind.

[0019] In some embodiments, the axial directions of the unwinding roller, the first pressing roller, the second pressing roller, the transfer roller, and the winding roller all extend along the second direction.

[0025] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0026] refer to Figure 1 , Figure 1 A three-dimensional diagram of a cutting machine 1 provided in an embodiment of the present utility model is shown.

[0027] like Figure 1 As shown, the technical solution adopted by the present invention is a cutting machine 1, comprising a machine platform 2 and a cutting device 3, wherein a transmission line 20 is provided on the top of the machine platform 2, and the transmission line 20 is arranged along a first direction ( Figure 1 The cutting device 3 is provided on the transmission line 20 along the second direction ( Figure 1 The drive assembly and the cutter assembly are arranged on one side of the transmission line 20. The cutter assembly includes a cutter box 50, which is arranged above the transmission line 20. The drive assembly is connected to the cutter box 50 and is used to drive the cutter box 50 relative to the transmission line 20 along the third direction ( Figure 1 The cutter box 50 is open at the bottom and contains a plurality of cutters. Each cutter extends along a third direction and is used to press down and cut the silicone gasket 21 through the drive assembly. The first direction, the second direction, and the third direction are perpendicular to each other.

[0028] The cutter assembly further includes a stopper plate 51, which is disposed on top of the transmission line 20 and corresponds to the cutter box 50. The stopper plate 51 extends along a first direction and includes a predetermined cutting channel 52, which is configured to correspond to the plurality of cutters and is used to prevent the silicone gasket 21 from moving with the plurality of cutters.

[0029] The cutting machine 1 provided in the present application presses down along the third party through the cutting box 50, and the multiple cutters arranged inside it cut the silicone gasket 21. Through the design of the preset cutting channel 52, it can ensure that the contact between the cutter and the silicone gasket 21 is more precise, reducing the cutting error, improving the consistency and quality of the product, and at the same time avoiding the silicone gasket 21 from moving up with the cutter after cutting due to its own adhesion.

[0030] In some embodiments, reference Figure 1 The driving assembly includes a first guide post 40, a second guide post 41 and a connecting plate 42. The first guide post 40 and the second guide post 41 are arranged parallel to each other along the third direction. The connecting plate 42 connects the tops of the first guide post 40 and the second guide post 41 respectively.

[0031] In some embodiments, reference Figure 1 The drive assembly further includes a fixed block 43 and a lifting motor 44. The fixed block 43 is disposed through the first guide post 40 and the second guide post 41. The lifting motor 44 is disposed on a side of the fixed block 43 facing the transmission line 20 along the second direction and includes a lifting connection end 440, the bottom of which is connected to the top of the cutter box 50.

[0032] For example, the fixing block 43 is inserted through the first guide post 40 and the second guide post 41, making the cutting machine 1 more stable during the cutting process and reducing errors caused by mechanical vibration or impact. The rapid response capability of the lifting motor 44 can improve cutting efficiency, making the cutting machine 1 more efficient during the cutting process. The integrated design of the fixing block 43 and the lifting motor 44 reduces the number of connecting cables, which helps improve system reliability and reduce the impact of external interference on the system, thereby reducing maintenance costs.

[0033] In some embodiments, reference Figure 1 The drive assembly further includes an adjustment assembly, which includes a knob 45 and a screw 46. The screw 46 extends along the third direction and is disposed between the first guide post 40 and the second guide post 41. One end of the screw 46 is connected to the fixed block 43, and the other end is disposed through the connection and is rotatably connected to the knob 45. Rotating the knob 45 drives the fixed block 43 to move up and down along the third direction relative to the first guide post 40 and the second guide post 41.

[0034] For example, the design of the knob 45 allows the operator to adjust the height or position of the cutter box 50 by a simple rotation action, thereby improving the convenience of operation.

[0035] In some embodiments, reference Figure 1The cutting machine 1 further includes a film laminating device 6, which includes an unwinding assembly and a rewinding assembly. The unwinding assembly includes a first frame 70, an unwinding roller 71, a first pressure roller 72, a second pressure roller 73, and a transfer roller 74. The first frame 70 extends along the third direction and is located on the other side of the transmission line 20 along the second direction. The unwinding roller 71, the first pressure roller 72, the second pressure roller 73, and the transfer roller 74 are all located on the side of the first frame 70 facing the transmission line 20.

[0036] An unwinding roller 71 is located at the top of the first frame 70 and is used to place and install the protective film. A first pressing roller 72 and a second pressing roller 73 are spaced apart along the first direction and are positioned in contact with the silicone gasket 21. A transfer roller 74 is located between the unwinding roller 71 and the first pressing roller 72, allowing the protective film to circulate around the transfer roller 74 and be pressed against the surface of the silicone gasket 21 by the first pressing roller 72 and the second pressing roller 73.

[0037] For example, the design of the unwinding roller 71, first pressure roller 72, and second pressure roller 73 allows for precise control of the tension of the protective film, maintaining its stability during the cutting process and preventing subsequent cutting errors due to uneven tension. The design of the transfer roller 74 allows the protective film to circulate around it, with the first and second pressure rollers 72 and 73 pressing against the surface of the silicone gasket 21. This helps improve the quality of the fit between the protective film and the silicone gasket 21, ensuring a neat, bubble-free edge on the cut product.

[0038] In some embodiments, reference Figure 1 The winding assembly includes a second frame 80, a winding roller 81, and a drive motor 82. The second frame 80 is located on one side of the first frame 70 along the first direction. The winding roller 81 is located at the top of the second frame 80 on the side facing the transmission line 20 and is used to wind up the waste protective film that has circulated around the transfer roller 74. The drive motor 82 is located on the other side of the second frame 80 corresponding to the winding roller 81 and is used to drive the winding roller 81 to rotate and rewind.

[0039] In some embodiments, reference Figure 1 The axial directions of the unwinding roller 71 , the first pressing roller 72 , the second pressing roller 73 , the transfer roller 74 and the winding roller 81 all extend along the second direction.

[0040] For example, the axially extended design helps to better control the tension of the diaphragm, especially in the unwinding system. By adjusting the movement of the unwinding roller 71 and the traction roller, the tension can be effectively controlled to ensure the stability of the diaphragm during transportation.

[0041] In some embodiments, reference Figure 1The film laminating device 6 further includes a cutter assembly, which includes a mounting frame 90 and a film cutter. The mounting frame 90 is provided on the other side of the first frame 70 along the first direction and is provided on both sides of the transmission line 20 along the second direction. The film cutter is provided in the mounting frame 90 and is used to cut the protective film.

[0042] Exemplarily, the excess protective film is cut by a film cutting knife to separate adjacent silicone gaskets 21 and ensure the smoothness of the edges of the silicone gaskets 21 after cutting.
