Description

Technical Field

[0001] The present invention relates to the technical field of hard and brittle bar cutting, and particularly to a cutting machine. Background Art

[0002] The single-station cutting machine of the prior art places a hard and brittle bar on a roller group and clamps it through an auxiliary feeding mechanism on the side, or sucks it through a suction cup device at the front end and then feeds it. Shifting materials in this way is achieved based on the outer surface of the hard and brittle bar. Although the existing lifting technology has advanced rapidly, the outer surface of the hard and brittle bar is still uneven, resulting in a large parallelism error between the front and rear cut surfaces and poor cutting quality.

[0003] More information related to the above technical solutions can be found in the following documents:

[0004] In the Chinese utility model patent with the publication number CN201755873U, a double-V-shaped silicon bar support seat for a silicon bar cutting machine is disclosed, which includes a bottom plate, a left V-shaped positioning seat, a right V-shaped positioning seat, an ear seat, a rotation center hole, a synchronous ejector rod hole, and a circumferential positioning hole. The left V-shaped positioning seat and the right V-shaped positioning seat are symmetrically arranged on the left and right sides of the bottom plate. Ear seats are symmetrically arranged on both sides of the V-shaped positioning surface. A synchronous ejector rod hole is opened below the V-shaped positioning surface. A rotation center hole is opened at the center of the bottom plate, and a circumferential positioning hole is arranged outside the rotation center hole. The double-V-shaped positioning seat structure makes the silicon bar to be cut not only reliably positioned, but also has great rigidity after clamping, eliminating the shaking phenomenon of the silicon bar to be cut during the cutting process, improving the flatness of the cutting end surface of the silicon bar. The setting of the ear seat and the synchronous ejector rod hole facilitates the installation of a swing-arm pressing mechanism, and the setting of the rotation center hole and the circumferential positioning hole meets the rotation and positioning requirements of the double-V-shaped silicon bar support seat.

[0005] In the Chinese utility model patent with the publication number CN201755874U, a synchronous clamping mechanism for a silicon bar cutting fixture includes a handwheel, a screw shaft, a tappet, a V-shaped positioning seat, an adjusting screw, a pin shaft, a right pressing arm, a left pressing arm, a movable pressing block, a pressure regulating screw, a spring seat, a return spring, and a silicon bar to be clamped. Two V-shaped positioning surfaces are arranged on the V-shaped positioning seat at intervals on the same straight line. The left and right pressing arms correspond to each other and have the same shape. Movable pressing blocks are installed at the outer ends of the two pressing arms. A tappet is arranged between the screw shaft and the adjusting screw, and the axis of the tappet is perpendicular to the symmetry center line of the V-shaped positioning surface. A pressing arm return mechanism is arranged between the left and right pressing arms and the V-shaped positioning seat. The silicon bar to be clamped is placed on the V-shaped positioning surface and is synchronously clamped by the left pressing arm and the right pressing arm. Since the silicon bar to be clamped adopts a horizontal V-shaped groove support structure and is synchronously clamped by the left and right pressing arms, the overall rigidity of the fixture during the cutting of the silicon bar to be clamped is improved, and the flatness of the cutting end surface of the silicon bar to be clamped is greatly improved.

[0006] In the process of implementing the present invention, the inventors found the following problems in the prior art. In the prior art, only a single cutting surface is supported, which can ensure the flatness of a single cutting surface, but cannot ensure the parallelism between two cutting surfaces, which is not conducive to the use of hard and brittle rod materials. Summary of the Invention

[0007] Therefore, a cutting machine is needed to solve the technical problem in the prior art that only a single cutting surface is supported, which can ensure the flatness of a single cutting surface, but cannot ensure the parallelism between two cutting surfaces.

[0008] To achieve the above object, the inventors provide a cutting machine, including a base, a cutting mechanism, and more than two clamping mechanisms;

[0009] The base is used for transporting hard and brittle rod materials, the cutting mechanism is arranged on the base, and the cutting mechanism is used for cutting the hard and brittle rod materials;

[0010] More than two of the clamping mechanisms are arranged along the transportation direction of the hard and brittle rod materials. The clamping mechanisms are used for clamping the hard and brittle rod materials in the vertical direction and can adjust the position of the hard and brittle rod materials in the vertical direction. Any two of the clamping mechanisms cooperate with each other to adjust the centers of the hard and brittle rod materials clamped by the two clamping mechanisms to be on the same horizontal plane.

[0011] As an embodiment of the present invention, the clamping mechanism includes a pressing component and a supporting component. The supporting component is used for supporting the hard and brittle rod material upward, the pressing component is used for pressing the hard and brittle rod material downward, and the pressing component and the supporting component cooperate with each other to adjust the height of the center of the hard and brittle rod material in the vertical direction.

[0012] As an embodiment of the present invention, the pressing component includes a first driving unit, a pressing block, and a displacement sensor. The first driving unit is used for driving the pressing block to press the hard and brittle rod material downward, and the displacement sensor is used for detecting the position information of the pressing block and sending the position information of the pressing block to the control module of the cutting machine.

[0013] As an embodiment of the present invention, the supporting component includes a second driving unit, a jacking block, and a sliding shaft. The jacking block is arranged on the sliding shaft, the sliding shaft is in transmission connection with the second driving unit, and the second driving unit is used for driving the sliding shaft to drive the jacking block to jack the hard and brittle rod material upward.

[0014] As an embodiment of the present invention, a rack is provided on the base along the transportation direction. The support assembly includes a third driving unit and a first gear. The first gear is arranged on the output shaft of the third driving unit. The third driving unit is used to drive the clamping mechanism to move relatively in the transportation direction through the cooperation between the first gear and the rack.

[0015] As an embodiment of the present invention, the cutting machine further includes a floating support mechanism. The floating support mechanism is arranged on one side of the cutting mechanism and is used to support the brittle rod material cut by the cutting mechanism.

[0016] As an embodiment of the present invention, a rack is provided on the base along the transportation direction. The floating support mechanism includes a fourth driving unit and a second gear. The second gear is arranged on the output shaft of the fourth driving unit. The fourth driving unit is used to drive the floating support mechanism to move relatively in the transportation direction through the cooperation between the second gear and the rack.

[0017] As an embodiment of the present invention, the floating support mechanism includes more than two support components. The more than two support components are arranged in a row along the transportation direction. Each support component includes two relatively arranged support parts, and the two relatively arranged support parts are respectively located on the left and right sides of the brittle rod material.

[0018] As an embodiment of the present invention, the cutting machine further includes a roller frame. Two rows of roller groups are arranged on the roller frame. Each roller group includes a plurality of rollers arranged in a row along the transportation direction, and the rollers are used to transport the brittle rod material.

[0019] As an embodiment of the present invention, a guide rail is provided on the base along the transportation direction, and a chute is provided on the clamping mechanism to cooperate with the guide rail.

[0020] Different from the prior art, in the above technical solution, more than two clamping mechanisms are arranged along the transportation direction of the brittle rod material. The clamping mechanisms are used to clamp the brittle rod material in the vertical direction and can adjust the position of the brittle rod material in the vertical direction. Any two of the clamping mechanisms cooperate to adjust the centers of the brittle rod material clamped by the two clamping mechanisms to be on the same horizontal plane. In this way, during use, the first clamping mechanism fixes one end of the brittle rod material to be cut, and the second clamping mechanism fixes the other end of the brittle rod material to be cut. The clamping mechanism can adjust the position of the brittle rod material in the vertical direction to make the centers of the two cutting surfaces on the same horizontal plane, thereby ensuring the parallelism of the two cutting surfaces and facilitating the transportation and use of the brittle rod material.

[0062] In the description of this specification, it should be understood that the orientation terms such as "upper", "lower", "left", and "right" described in the embodiments of this application are described from the angles shown in the drawings, and should not be construed as limitations on the embodiments of this application.

[0063] Please refer to Figures 1 to 12 , this embodiment relates to a cutting machine, which includes a base 1, a cutting mechanism 2, more than two clamping mechanisms 3, a floating support mechanism 5, and a roller frame 6; the base 1 is used to transport brittle rod materials 4, and the base 1 may include a transport mechanism in this embodiment, and the transport mechanism can be used to transport brittle rod materials 4. The cutting mechanism 2 is arranged on the base 1, and the cutting mechanism 2 is used to cut the brittle rod materials 4.

[0064] Optionally, the cutting machine further includes a roller frame 6, and two rows of roller groups are arranged on the roller frame 6. The roller group includes a plurality of rollers arranged along the transport direction, and the rollers are used to transport the brittle rod materials 4. Power can be provided for each roller to transport the brittle rod materials 4.

[0065] In this embodiment, more than two clamping mechanisms 3 are arranged along the transport direction of the brittle rod materials 4. The clamping mechanisms 3 are used to clamp the brittle rod materials 4 in the vertical direction (the direction indicated by the arrow z in the figure), and can adjust the position of the brittle rod materials 4 in the vertical direction (the direction indicated by the arrow z in the figure). Any two of the clamping mechanisms 3 cooperate with each other to adjust the centers of the brittle rod materials 4 clamped by the two clamping mechanisms 3 to be on the same horizontal plane.

[0066] In this embodiment, as Figures 2 to 4 shown, at least two clamping mechanisms 3 are required to clamp both ends of the brittle rod materials 4 to be cut. The first clamping mechanism 3 first clamps one end of the brittle rod materials 4 to fix the height of the center point of one end of the brittle rod materials 4, and the other clamping mechanism 3 clamps the other end of the brittle rod materials 4. By adjusting the position of the other end of the brittle rod materials 4 in the vertical direction (the direction indicated by the arrow z in the figure), the height of the center point of the other end of the brittle rod materials 4 is made equal to the height of the center point of one end of the brittle rod materials 4, ensuring the parallelism of the two cutting surfaces when cutting both ends of the brittle rod materials 4, facilitating the transportation and use of the brittle rod materials 4, ensuring the uniformity of the dimensions of the brittle rod materials 4, and avoiding waste.

[0067] Optionally, a guide rail 12 arranged along the transport direction is provided on the base 1, and a sliding groove 33 that cooperates with the guide rail 12 is provided on the clamping mechanism 3. In this way, the clamping mechanism 3 can move relatively along the extension direction of the guide rail 12.

[0068] Optionally, as Figures 5 to 7 shown, the clamping mechanism 3 includes a frame 34, a pressing component 31 and a supporting component 32 arranged on the frame 34. The pressing component 31 is arranged above the supporting component 32. The supporting component 32 is used to support the brittle rod 4 upward, and the pressing component 31 is used to press the brittle rod 4 downward. The pressing component 31 and the supporting component 32 cooperate with each other to adjust the height of the center of the brittle rod 4 in the vertical direction (the direction indicated by the arrow z in the figure).

[0069] At this time, by pressing the brittle rod 4 downward with the pressing component 31 and supporting the brittle rod 4 upward with the supporting component 32, the height of the brittle rod 4 in the vertical direction (the direction indicated by the arrow z in the figure) can be adjusted. The brittle rod 4 is a round rod. Even if there are defects or uneven places on the surface of the brittle rod 4, through the cooperation of the pressing component 31 and the supporting component 32, the height of the center (center of the circle) of the brittle rod 4 in the vertical direction (the direction indicated by the arrow z in the figure) can also be adjusted.

[0070] Optionally, as Figure 8 shown, the pressing component 31 includes a first driving unit 311, a pressing block 312 and a displacement sensor 313. The first driving unit 311 is arranged on the frame 34, the output end of the first driving unit 311 is arranged downward, the pressing block 312 is arranged on the output end of the first driving unit 311, and the first driving unit 311 is used to drive the pressing block 312 to press the brittle rod 4 downward.

[0071] The displacement sensor 313 is connected to the output end of the first driving unit 311. The displacement sensor 313 is used to detect the position information of the pressing block 312 and send the position information of the pressing block 312 to the control module of the cutting machine.

[0072] At this time, the output height of the pressing component 31 of the clamping mechanism 3 is fixed. The pressing component 31 of the first clamping mechanism 3 presses downward, and the displacement sensor 313 detects the distance that the pressing block 312 moves downward, so as to obtain the vertical height of the brittle rod 4 clamped by the first clamping mechanism 3. The vertical height information of the brittle rod 4 clamped by the first clamping mechanism 3 is sent to the second clamping mechanism 3, and the second clamping mechanism 3 adjusts according to the actual situation to make the position clamped by the second clamping mechanism 3 correspond to the position clamped by the first clamping mechanism 3, so as to ensure the parallelism of the two cutting surfaces when the two ends of the brittle rod 4 are cut.

[0073] Optionally, the pressing block 312 is made of a soft material. For example, rubber, nylon, plastic, etc. By contacting the upper surface of the brittle rod with the soft material, it is not easy to crush the brittle rod.

[0074] Optionally, asFigures 9 to 11 As shown in the figure, the support assembly 32 includes a second driving unit 321, a pressing block 322, a sliding sleeve 324, and a sliding shaft 323. The second driving unit 321 is arranged on the frame 34, the output end of the second driving unit 321 is arranged upward, the pressing block 322 is arranged on the output end of the second driving unit 321, and the second driving unit 321 is used to drive the pressing block 322 to press the brittle rod 4 upward.

[0075] The sliding sleeve 324 is arranged on the frame 34, the sliding shaft 323 is arranged in the sliding sleeve 324, the pressing block 322 is arranged on the sliding shaft 323, the sliding shaft 323 is in transmission connection with the second driving unit 321, and the second driving unit 321 is used to drive the sliding shaft 323 to drive the pressing block 322 to press the brittle rod 4 upward. The sliding shaft 323 pushes upward along the sliding sleeve 324, and finally drives the pressing block 322 to push upward. At this time, the pressing block 322 can press the brittle rod 4 upward to ensure the height position of the brittle rod 4.

[0076] Optionally, the pressing block 322 is set to a V-shaped structure to support the brittle rod 4 upward. The pressing block 322 is set to a V-shaped structure to support the brittle rod 4 from below, prevent the brittle rod 4 from running left and right, and ensure the position height of the brittle rod 4 in the vertical direction (the direction indicated by the arrow z in the figure).

[0077] Optionally, as Figure 3 and Figure 9 shown, a rack 11 arranged along the transportation direction is provided on the base 1. The support assembly 32 includes a third driving unit 325 and a first gear 326. The first gear 326 is arranged on the output shaft of the third driving unit 325. The third driving unit 325 is used to drive the clamping mechanism 3 to move relatively in the transportation direction through the cooperation of the first gear 326 and the rack 11. In this way, the rotation of the first gear 326 can be driven, so as to drive the clamping mechanism 3 to move relatively on the base 1, and the brittle rod 4 can be driven to move relatively in the transportation direction.

[0078] Optionally, as Figure 1 and Figure 12 shown, the cutting machine further includes a floating support mechanism 5. The floating support mechanism 5 is arranged on one side of the cutting mechanism 2 and is used to support the brittle rod 4 cut by the cutting mechanism 2. When cutting the brittle rod 4, the section cut from the left side of the brittle rod 4 can be supported and transported away.

[0079] Optionally, a rack 11 is provided on the base 1 along the transportation direction. The floating support mechanism 5 includes a fourth driving unit 51 and a second gear 52. The second gear 52 is provided on the output shaft of the fourth driving unit 51. The fourth driving unit 51 is used to drive the floating support mechanism 5 to move relatively in the transportation direction through the cooperation of the second gear 52 and the rack 11. In this way, the rotation of the second gear 52 can be driven, so as to drive the floating support mechanism 5 to move relatively on the base 1, and the brittle rod 4 can be driven to move relatively in the transportation direction.

[0080] Optionally, the floating support mechanism 5 includes more than two support members 53. The more than two support members 53 are arranged along the transportation direction. The support member 53 includes two relatively arranged support parts 531. The two relatively arranged support parts 531 are respectively located on the left and right sides of the brittle rod 4. The two support parts 531 support the brittle rod 4 in a V shape to prevent movement in the vertical direction (the direction indicated by the arrow z in the figure).

[0081] Optionally, the floating support mechanism 5 further includes a displacement adjusting member 54. The displacement adjusting member 54 is arranged on one side of the fourth driving unit 51. The displacement adjusting member 54 is used to adjust the distance between the second gear 52 and the rack 11 to ensure the meshing between the second gear 52 and the rack 11.

[0082] During use, the roller rack 6 transports the brittle rod 4 to the designated position. The first clamping mechanism 3 first clamps one end of the brittle rod 4 to fix the height of the center point of one end of the brittle rod 4, while the other clamping mechanism 3 clamps the other end of the brittle rod 4. Through the mutual cooperation of the pressing component 31 and the supporting component 32, the position of the other end of the brittle rod 4 in the vertical direction (the direction indicated by the arrow z in the figure) is adjusted, so that the height of the center point of the other end of the brittle rod 4 is equal to the height of the center point of one end of the brittle rod 4; the cutting mechanism 2 cuts downward to cut one end of the brittle rod 4. The floating support mechanism 5 supports the cut section and transports the cut part away. The clamping mechanism 3 transports inward, the cutting mechanism 2 cuts the other end and cuts it off. The clamping mechanism 3 puts down the two ends of the brittle rod 4 and continues to clamp the next section of the brittle rod 4. In other embodiments, there may also be other cutting methods. For example, the floating support mechanism 5 and the clamping mechanism 3 cooperate to support the two ends of the brittle rod 4. The height data of the clamping mechanism 3 is sent to the floating support mechanism 5. Through the cooperation of the floating support mechanism 5 and the two clamping mechanisms 3, any two of the mechanisms support the brittle rod 4, so as to ensure the continuity of cutting.

[0083] Different from the prior art, the above technical solution fixes one end of the brittle rod 4 to be cut by the first clamping mechanism 3, and fixes the other end of the brittle rod 4 to be cut by the second clamping mechanism 3. The clamping mechanism 3 can adjust the position of the brittle rod 4 in the vertical direction (the direction indicated by the arrow z in the figure), so that the centers of the two cutting surfaces are on the same horizontal plane, thereby ensuring the parallelism of the two cutting surfaces and facilitating the transportation and use of the brittle rod 4.

[0084] It should be noted that although the above embodiments have been described in this text, the patent protection scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, any changes and modifications made to the embodiments described in this text, or equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, and directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present invention.
