Description

Technical Field

[0001] The invention relates to the technical field of cutting devices, in particular to a cutting and turning platform for a notebook shell. Background Art

[0002] CNC machining centers are widely used in the field of laptop casing processing, often used to manufacture laptop casing molds and directly cut laptop shells. Many mold manufacturing companies use them as their main processing equipment for producing laptop plastic casing molds.

[0003] The core function of the positioning mechanism is to precisely guide and secure the workpiece directly beneath the cutting head, ensuring accurate cutting positioning. However, traditional clamping mechanisms continuously cover the space above the workpiece and cannot be withdrawn. This causes the cutting head to be directly blocked by the clamping components during machining, preventing it from directly affecting the area to be cut. At this point, the machining process must be paused, and the clamping components must be removed manually through a secondary operation before the cutting action can continue. This design flaw not only interrupts the continuity of the machining process but also adds an additional manual intervention step, resulting in a significant reduction in machining efficiency, which is contrary to the efficient and automated production requirements pursued by CNC machining centers.

[0014] (3) Beneficial effects Compared with the prior art, the present invention provides a cutting and flipping platform for a notebook shell, which has the following beneficial effects: 1. The cutting and turning platform of the notebook shell is set up with a positioning mechanism. The hollow connecting strip 71 cooperates with the piston of the pressing strip and the air drive structure of the tube and the hollow block to achieve automatic correction when the workpiece contacts and automatic withdrawal of the guide frame 76 after positioning is completed. It ensures that the workpiece is accurately positioned directly under the cutting head and avoids the guide frame blocking the cutting area, ensuring the continuity and accuracy of the processing process.

[0015] 2. The cutting and flipping platform of the notebook shell is set up with a wiping mechanism. When the pressing bar is compressed, the driving gear and the driving rack engage and rotate, driving the wiping conveyor belt to circulate and clean the surface of the workpiece.

[0016] 3. The cutting and flipping platform of the notebook shell is set up with a protective mechanism. The clamping force threshold is controlled by the pre-tightening force of the connecting spring. When the clamping force exceeds the threshold, the conical column slides and the spring is compressed to interrupt the force transmission, avoiding the workpiece from being crushed due to excessive force or the positioning mechanism from being stuck. This not only protects the integrity of the workpiece, but also extends the service life of key components of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1-9, a cutting and flipping platform for a notebook shell, comprising: a workpiece 4; a notebook shell to be processed; a machine body 1; a cutting head 2, which is arranged on the machine body 1 for processing and cutting the workpiece 4; a transmission mechanism 3, which is arranged at the bottom of the cutting head 2, for transmitting the workpiece 4 to the bottom of the cutting head 2 for processing; a flipping mechanism 5, which is arranged on the transmission mechanism 3, for clamping and rotating the workpiece 4; a protective mechanism 6, which is arranged on the flipping mechanism 5, for disconnecting the clamping when the clamping force is too large; a positioning mechanism 7, which is arranged on the flipping mechanism 5, for stably clamping the workpiece 4 to a suitable position; a wiping mechanism 8, which is arranged on the positioning mechanism 7, for wiping the workpiece 4 before clamping; the positioning mechanism 7 includes a hollow connecting bar 71, which is connected to the output end of the flipping mechanism 5, and a through tube 72 is connected to the hollow connecting bar 71, When the locking cam 75 is in the closed position, the locking cam 73 is in the closed position, and the block 73 is locked. At this point, the air inside the hollow connecting strip 71 is squeezed by the push of the pressing strip 77 and flows into the hollow block 73 through the through tube 72. Before the pressing strip 77 is compressed, the workpiece 4 first contacts the inclined surface of the guide frame 76. The inclined surface design of the guide frame 76 serves as a "correction" function - when the workpiece 4 contacts the inclined surface, it is guided to the center position of the guide frame 76, thereby achieving preliminary directional adjustment and ensuring the accuracy of the subsequent clamping position. After the air in the hollow connecting strip 71 enters the hollow block 73 through the through tube 72, it will exert pressure on the sealing plate 75 inside the hollow block 73. Under the action of air pressure, the sealing plate 75 overcomes the elastic force of spring 1 74 and moves away from the workpiece 4, and drives the guide frame 76 to slide synchronously toward the hollow block 73 through the long rod. At this time, the guide frame 76 maintains a sliding connection with the inner wall of the hollow connecting strip 71. After the guide frame 76 moves, the part that originally covered the top of the workpiece 4 gradually withdraws, releasing the space on the top of the workpiece 4. At this time, the workpiece 4 has been accurately positioned at the clamping center position of the two positioning mechanisms 7, meeting the position accuracy requirements of the cutting process.Through the inclined design of the guide frame 76, the workpiece 4 will be automatically guided to the center position of the two positioning mechanisms 7 when it contacts the positioning mechanism 7, that is, directly below the cutting head 2. This "correction" function avoids the cutting position deviation caused by the workpiece 4 being placed crookedly or transported, directly improving the cutting accuracy of key parts such as heat dissipation holes and edge contours, and reducing the defective rate. After positioning is completed, the guide frame 76 withdraws from the space above the workpiece 4 to prevent it from blocking the cutting area. One end of the spring 1 74 is fixedly connected to the sealing plate 75, and the other end of the spring 1 74 is fixedly connected to the inner wall of the hollow block 73.

[0021] The transmission mechanism 3 includes a base frame 31 , on which a driving motor 32 and a conveyor belt 33 are provided. The output end of the driving motor 32 is connected to the conveyor belt 33 for driving the conveyor belt 33 to move.

[0022] The flipping mechanism 5 includes an inverted U-shaped frame 51, which is fixedly connected to the side of the base frame 31. A vertical telescopic motor 52 is fixedly connected to the inverted U-shaped frame 51, and the output end of the vertical telescopic motor 52 is fixedly connected to the horizontal telescopic motor 53. The output end of the horizontal telescopic motor 53 is fixedly connected to a driving head 54 through a protective mechanism 6. The end of the driving head 54 close to the horizontal telescopic motor 53 is fixedly connected to a stepping motor 55. The output end of the stepping motor 55 is fixedly connected to the hollow connecting bar 71. The inverted U-shaped frame 51 serves as a fixed bracket and is directly connected to the side of the base frame 31 of the transmission mechanism 3, providing a stable installation foundation for the entire flipping mechanism 5 to ensure that the structure does not deviate during subsequent actions. The vertical telescopic motor 52 is vertically fixed on the inverted U-shaped frame 51, and its output end is connected to the horizontal telescopic motor 53. When the vertical telescopic motor 52 is activated, the telescopic rod is extended and retracted, driving the transverse telescopic motor 53, the drive head 54, the stepper motor 55, and the positioning mechanism 7 to move vertically as a whole, adjusting the height of the workpiece 4. The output end of the transverse telescopic motor 53 is connected to the drive head 54. When the transverse telescopic motor 53 is activated, the transverse telescopic motor 53 drives the drive head 54, the stepper motor 55, and the positioning mechanism 7 to move horizontally as a whole, clamping the workpiece 4. The stepper motor 55 is fixed to the end of the drive head 54 near the transverse telescopic motor 53, and its output end is directly fixed to the hollow connecting bar 71 of the positioning mechanism 7. When the stepper motor 55 is activated, it drives the output shaft to rotate, precisely controlling the angle. This allows the hollow connecting bar 71, positioning mechanism 7, and the clamped workpiece 4 to rotate synchronously around the axis of the stepper motor 55 output shaft, flipping the workpiece 4. The vertical telescopic motor 52 and the horizontal telescopic motor 53 coordinate to adjust the vertical and horizontal position of the workpiece 4, ensuring that the workpiece 4 can be accurately moved to the processing area of ​​the cutting head 2. The stepper motor 55, through its rotational drive, flips the workpiece 4 at an angle, meeting the requirements of multi-faceted cutting. The three mechanisms work together, making the flip mechanism 5 the core execution component of the cutting platform's "move-flip" function, significantly enhancing the equipment's flexibility in processing complex-shaped shells.

[0023] The protective mechanism 6 includes a drive sleeve 61 and a drive shaft 62. The drive sleeve 61 is fixedly connected to the output end of the horizontal telescopic motor 53. The drive shaft 62 is fixedly connected to the drive head 54. The drive sleeve 61 is slidably connected to the outer wall of the drive shaft 62. A connecting block 63 is fixedly connected to the drive shaft 62. A threaded rod 64 is threadedly connected to the drive sleeve 61. The bottom of the threaded rod 64 is rotatably connected to a square block 65. A connecting spring 66 is provided at the bottom of the square block 65. One end of the connecting spring 66 is fixedly connected to the bottom of the square block 65. The other end of the connecting spring 66 is fixedly connected to a conical column 67. The conical column 67 and the square block 65 are both slidably connected to the inner wall of the drive sleeve 61. A scale 68 is set on the top of the drive sleeve 61. When the horizontal telescopic motor 53 is started and pushes the drive sleeve 61, the drive sleeve 61 contacts the connecting block 63 through the internal conical column 67. The connecting block 63 is fixed on the drive shaft 62, and the thrust is transmitted to the drive shaft 62, thereby driving the drive head 54 and the positioning mechanism 7 to move toward the workpiece 4 to complete the clamping. At this time, the connecting spring 66 is not compressed, and the force transmission path remains intact. If the clamping force of the workpiece 4 exceeds the preset threshold value due to position deviation, excessively hard material, or other reasons, that is, the preload force of the connecting spring 66, the connecting block 63 on the drive shaft 62 will generate a thrust on the conical column 67 that exceeds the elastic force of the connecting spring 66. At this time: the conical column 67 is compressed and slides upward along the inner wall of the drive sleeve 61; the connecting spring 66 is further compressed to absorb the overload energy; the force transmission between the drive sleeve 61 and the drive shaft 62 is interrupted, and the drive shaft 62 no longer moves synchronously with the drive sleeve 61, avoiding excessive clamping force from being transmitted to the workpiece 4 or the positioning mechanism 7, preventing the workpiece 4 from being crushed or the mechanism from being stuck.

[0024] The wiping mechanism 8 includes a side mounting groove 81, which is arranged on the pressing strip 77. A rotating roller 82 is rotatably connected to the inner wall of the side mounting groove 81. The surface of the rotating roller 82 is transmission-connected to the wiping conveyor belt 83. The shaft of the rotating roller 82 is fixedly connected to the driving gear 84. The driving rack 85 is fixedly connected to the hollow connecting strip 71. The side mounting groove 81 of the wiping mechanism 8 is directly opened on the pressing strip 77. The rotating roller 82 is rotatably connected to the inner wall of the side mounting groove 81 through the rotating shaft. The wiping conveyor belt 83 is wrapped around the surface of the rotating roller 82 to form an annular transmission structure. The rotating shaft of the rotating roller 82 extends out of the side mounting groove 81 and is fixedly connected to the driving gear The wheel 84 is fixed to the outer wall of the hollow connecting bar 71, and the driving rack 85 is fixed to the outer wall of the hollow connecting bar 71, forming a meshing relationship with the driving gear 84. The pressing bar 77 drives the wiping conveyor 83 of the wiping mechanism 8 to press the workpiece 4. When the pressing bar 77 is compressed into the hollow connecting bar 71, the driving rack 85 fixedly connected to the hollow connecting bar 71 will drive the driving gear 84 to rotate, and the driving gear 84 drives the rotating roller 82 to rotate. The rotating roller 82 drives the rotation to wipe and clean the part that contacts the workpiece 4. The surface of the wiping conveyor 83 is made of a soft cleaning material, such as flannel, sponge or fiber fabric, which will directly contact and rub with the surface of the workpiece 4 during the rotation process. Since the wiping action occurs before the pressing bar 77 is fully compressed, that is, before the positioning mechanism 7 completes the clamping, the wiping conveyor 83 can clean the dust, debris or oil on the surface of the workpiece 4 in advance, avoiding impurities affecting the stability of the subsequent clamping and the cutting quality, such as debris entering the cutting area and causing scratches.

[0025] The surface of the conveyor belt 33 is provided with anti-slip grooves, which are used to increase the friction with the workpiece 4 and prevent the workpiece 4 from sliding and offsetting during transmission. A shock-absorbing pad is provided at the bottom of the base frame 31. The shock-absorbing pad is made of rubber and is used to absorb the vibration generated when the drive motor 32 is running, reducing the impact on cutting accuracy. A sealing ring is provided on the edge of the sealing plate 75. The material is nitrile rubber, which is used to improve the air tightness of the hollow block 73. Bearings are provided at both ends of the transmission roller of the conveyor belt 33. The type of bearing is deep groove ball bearing, which is used to reduce transmission resistance and increase the life of the transmission mechanism 3. An operation panel is provided on the surface of the body 1. The operation panel is integrated with an emergency stop button, a mode switching switch and a status display screen for manual intervention in equipment operation and real-time monitoring of the status of each mechanism.

[0026] In summary, the laptop case cutting and turning platform activates the drive motor 32, which drives the conveyor belt 33 through the output end, transporting the laptop case workpiece 4 to be processed from its initial position toward the cutting head 2. The anti-slip grooves on the surface of the conveyor belt 33 increase friction with the workpiece 4, preventing it from slipping during transport. The rubber cushions at the bottom of the base frame 31 absorb vibrations caused by the drive motor 32, minimizing the impact on subsequent cutting accuracy. Deep-groove ball bearings are installed at both ends of the conveyor belt 33's drive rollers to reduce transmission resistance and enhance the operational stability and lifespan of the conveyor mechanism 3.

[0027] An inverted U-shaped frame 51 is fixed to the side of the base frame 31, providing stable support for the tilting mechanism 5. The vertical telescopic motor 52 is activated, and through the telescopic rod, it drives the horizontal telescopic motor 53, drive head 54, stepper motor 55, and positioning mechanism 7 to move vertically, adjusting the height of the workpiece 4 to bring it closer to the processing area of ​​the cutting head 2. The horizontal telescopic motor 53 is activated, and its output terminal pushes the protection mechanism 6 and drive head 54 horizontally toward the workpiece 4, driving the positioning mechanism 7 to simultaneously approach the workpiece 4 in preparation for clamping.

[0028] Driven by the transverse telescopic motor 53, two symmetrically arranged hollow connecting bars 71 approach the workpiece 4, simultaneously driving the entire assembly, including the through tube 72, hollow block 73, and guide frame 76. The workpiece 4 first contacts the inclined surface of the guide frame 76, which guides the workpiece 4 toward its center, completing the initial correction and avoiding positional deviation caused by skewed placement or misaligned transport. The guide frame 76 continues to move with the hollow connecting bars 71 until the pressing bar 77 contacts the surface of the workpiece 4. The workpiece 4 exerts a reverse pressure on the pressing bar 77, compressing it into the inner wall of the hollow connecting bars 71. The air inside the hollow connecting bars 71 is squeezed by the pushing of the pressing bar 77 and enters the hollow block 73 through the through tube 72. This air pressure pushes the sealing plate 75, overcoming the elastic force of spring 1 74 (one end of which is fixed to the sealing plate 75 and the other end is fixed to the inner wall of the hollow block 73), and moves it away from the workpiece 4. The sealing plate 75 drives the guide frame 76 to slide synchronously toward the hollow block 73 via the long rod, and the portion covering the top of the workpiece 4 gradually withdraws, freeing up space in the cutting area. At this point, the workpiece 4 has been accurately positioned at the center of the two positioning mechanisms 7, meeting the cutting accuracy requirements.

[0029] The transverse telescopic motor 53 continues to push the drive sleeve 61, and the drive sleeve 61 contacts the connecting block 63 on the drive shaft 62 through the internal conical column 67, transmitting the thrust to the drive shaft 62, thereby driving the drive head 54 and the positioning mechanism 7 to complete the clamping of the workpiece 4. During the clamping process, the position of the square block 65 can be adjusted by rotating the threaded rod 64 on the top of the drive sleeve 61 to change the initial compression of the connecting spring 66, and the scale 68 assists in precise adjustment. If the clamping force of the workpiece 4 exceeds the preload force of the connecting spring 66 due to position deviation, too hard material, etc., the thrust of the connecting block 63 on the conical column 67 exceeds the spring force, and the conical column 67 slides upward along the inner wall of the drive sleeve 61, interrupting the force transmission between the drive sleeve 61 and the drive shaft 62, thereby preventing excessive clamping force from damaging the workpiece 4.

[0030] As the pressure bar 77 is compressed into the hollow connecting bar 71, the side mounting slot 81 moves synchronously with the pressure bar 77, causing the drive gear 84 and the drive rack 85 to move relative to each other and engage and rotate. The drive gear 84 drives the rotating roller 82, which in turn drives the wiping conveyor belt 83 in a circular motion. The flexible material, such as velvet or sponge, on the surface of the wiping conveyor belt 83 rubs against the surface of the workpiece 4, removing impurities such as dust and debris. This wiping action is completed before the pressure bar 77 is fully compressed, ensuring a clean surface for the workpiece 4 during clamping and preventing impurities from affecting clamping stability or cutting quality.

[0031] After positioning and clamping, stepper motor 55 starts, driving the hollow connecting bar 71, positioning mechanism 7, and the clamped workpiece 4 to rotate synchronously around the output shaft of stepper motor 55, achieving an angular flip of the workpiece 4 and meeting the requirements of double-sided cutting. Cutting head 2 processes the positioned workpiece 4. The operation panel displays the status of each mechanism in real time. The emergency stop button and mode switch allow for manual intervention, ensuring safe operation of the equipment.

[0032] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
