Description

Technical Field

[0001] This utility model relates to the field of notebook shell cutting technology, and more specifically, to a notebook shell cutting device. Background Technology

[0002] In modern society, the application of computers has become increasingly widespread. As some users have higher and higher requirements for the portability of laptops for various purposes, the demand for laptops is also increasing.

[0003] As people's aesthetic requirements for laptop casings increase, and as the protective performance of laptops improves, the sides of laptop casings need to form an acute angle with the bottom to make the surface of the casing smoother and the sides more aesthetically pleasing. The current production method involves first cutting the raw materials into initial products of a certain size, then stamping the initial products into sheet-like preliminary products using a progressive die, and then using a secondary stamping die to shrink the edges of the preliminary products to form a full-circumference shrinking structure. In this process, because the cutting and conveying steps are independent and need to be processed on different equipment, the full-circumference shrinking process of laptop casings requires multiple loading, conveying, and unloading processes, making the production process cumbersome, complex, and inefficient.

[0004] To address the above issues, application number 202223177518.1, entitled "A Cutting Device for Laptop Shell Production," describes a device comprising: a conveyor mechanism including a conveyor belt and a drive assembly for intermittently moving the conveyor belt, with several support bars evenly distributed on the conveyor belt; an auxiliary mechanism including a mounting frame for mounting the conveyor mechanism and support rods mounted on the mounting frame, the support rods being located on both sides of the conveyor belt and the support bars sliding along the surface of the support rods; and a cutting mechanism including a lead screw drive assembly mounted on the mounting frame and a first motor driven by the lead screw drive assembly, the output shaft of the first motor having a cutting wheel. The drive assembly drives the conveyor belt to move intermittently, allowing raw materials to be conveyed and cut sequentially. This achieves an integrated conveying and cutting production process in laptop shell production, completing the cutting during the conveying process, simplifying the laptop shell production process, and improving production efficiency. Although the device has many beneficial effects, it still has the following problems: In actual use, the device drives the cutting wheel to move by driving the lead screw, and the motor makes it rotate at high speed to cut the raw materials. However, during high-speed cutting, a large amount of sharp metal shavings are generated for the aluminum alloy notebook shell raw materials. These shavings not only fly everywhere, making collection much more difficult and affecting workshop cleaning and subsequent waste disposal, but more seriously, the flying metal shavings can cause cuts, punctures and other safety hazards to the operators, posing a significant safety risk. Furthermore, due to the compression and collision of the aluminum alloy raw materials used in the laptop casing during transportation, as well as improper pre-processing, they are prone to bending and deformation. When cutting bent raw materials, the aforementioned device cannot accurately position and adjust their flatness, resulting in deviations between the actual cutting position and the design dimensions when the cutting wheel cuts along the predetermined path. This seriously affects the cutting accuracy, increases the product defect rate, wastes raw materials, increases production costs, and brings many inconveniences and troubles to actual production.

[0005] In view of this, we propose a cutting device for laptop casings. Utility Model Content

[0008] Preferably, the front outer wall of the dust collection box is connected to a closed door by a hinge, a filter plate is snapped into the inside of the dust collection box, a vacuum pump is fixedly connected to the side wall of the dust collection box, the suction end of the vacuum pump is connected to the inside of the dust collection box, and multiple vacuum pipes are also provided on the front outer wall of the dust collection box, and the multiple vacuum pipes are connected to the inside of the dust collection box.

[0009] Preferably, a drive motor is fixedly connected to the outer wall of the lifting frame, and a drive roller is connected to the output end of the drive motor. A leveling roller is also rotatably connected to the inner wall of the lifting frame, which is perpendicular to the multiple leveling rollers.

[0010] Preferably, a cutting motor is fixedly connected to the outer wall of the connecting frame, a cutting blade is connected to the output end of the cutting motor, a cavity is opened inside the connecting frame, a spring is fixedly connected to the top of the inner cavity of the cavity, and a telescopic frame is connected to the end of a plurality of springs.

[0011] Preferably, the telescopic frame has an opening on its outer wall, and a rotating roller is rotatably connected to the bottom of the telescopic frame.

[0012] Preferably, a dust collection box is provided on the top of the support shell, the dust collection box is in communication with the inside of the support shell, and the ends of the plurality of dust collection tubes are respectively connected to the outer wall of the dust collection box and the collection shell and extend into the inside of the dust collection box and the collection shell.

[0014] 3. Beneficial effects Compared to existing technologies, the advantages of this invention are as follows: During the actual cutting process, the raw material can be transported to the top of the collection shell via a belt conveyor. At this time, the electric push rod two can be activated to drive the moving frame to descend. Then, the cutting motor can be activated to drive the cutting blade to rotate. During the descent of the moving frame, the connecting frame and the telescopic frame one and telescopic frame two inside the support shell of the cutting assembly can be adaptively adjusted by the plasticity of spring one and spring two, so that it can still block the debris generated during the descent and cutting process. After descending to the limit position, the cutting assembly can be driven by the action of the lead screw motor and the lead screw. The component moves laterally to cut the raw material. During this cutting process, the generated debris is sucked from the top and bottom of the raw material by multiple suction pipes and transferred to the dust collection box. It is then intercepted and collected by the filter plate, reducing the problems of difficult-to-collect metal debris and high-speed splashing that may cause safety hazards. Furthermore, when the moving frame descends to its limit position and cutting begins, multiple rotating rollers at the bottom of the telescopic frame 1 and telescopic frame 2, together with the top of the collection shell, can position and press down on the bottom of the raw material to ensure the accuracy of the cutting. Before the cutting process, when the raw material is introduced, the lifting frame can be lowered by the hydraulic lifting cylinder, and then the drive roller can be rotated by the drive motor, thereby pulling the raw material. During this process, multiple leveling rollers can be adjusted to level the flatness of the raw material, reducing its excessive bending and affecting the subsequent cutting accuracy and the quality of the cut.

[0017] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" 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.

[0019] Please see Figure 1-5 This utility model provides a technical solution: A notebook casing cutting device includes a fixed base 100, a support base 110 and a dust collection box 130 at the bottom of the fixed base 100, a leveling roller 140 rotatably connected to the inner wall of the top of the fixed base 100, and a belt conveyor 120 and a collection shell 150 also provided on the inner wall of the fixed base 100. In some embodiments, the belt conveyor 120 mainly consists of a motor-driven roller and a belt, which is a conventional technology and is convenient for traction of raw material plates.

[0020] The top of the fixed base 100 is also fixedly connected to the fixed shell 200, the connecting plate 300 and the fixed frame 400. The top of the fixed shell 200 is connected to the hydraulic lifting cylinder 210. The output end of the hydraulic lifting cylinder 210 is connected to the lifting frame 220. The outer wall of the fixed shell 200 is fixedly connected to the controller 230. In some embodiments, the hydraulic lifting cylinder 210 mainly consists of a cylinder barrel, piston, piston rod, seals, and inlet / outlet ports. Its working principle is based on Pascal's law. When high-pressure oil enters the closed space formed by the cylinder barrel and piston through the inlet port, the oil pressure acts evenly on the piston surface, generating thrust to push the piston and its connected piston rod in a linear extension motion. When retraction is required, the oil is discharged from the outlet port. Under the action of an external load or an internal return mechanism, the piston drives the piston rod to retract. By controlling the amount and pressure of the oil entering and leaving the cylinder, the lifting speed and load-bearing capacity of the lifting cylinder can be precisely controlled. As existing technology, the hydraulic lifting cylinder 210's oil supply system generally consists of a hydraulic pump, oil tank, various control valves, and connecting pipelines. The hydraulic pump is the core power component of the oil supply system; common types include gear pumps and piston pumps.

[0021] Multiple connecting plates 300 are fixedly connected to the outer wall of electric push rod 310, and the output end of multiple electric push rod 310 is connected to guide plate 320. Electric push rod 410 is provided on the top of fixed frame 400, and the output end of electric push rod 410 is connected to movable frame 420. In some embodiments, a mounting bracket may be provided on the top of the guide plate 320, and a length measuring sensor may be provided on the top of the mounting bracket to facilitate the detection of the cutting length of the raw material, thereby enabling cutting at an appropriate length. Common laser length measuring sensors use the time-of-flight principle, which involves emitting a laser beam to irradiate the surface of the raw material. After the laser beam is reflected, it returns to the sensor. The sensor accurately measures the time difference between laser emission and reception, and calculates the distance from the sensor to the surface of the raw material by combining the speed of light. As the raw material moves, the sensor continuously collects distance data and records displacement changes. According to the preset cutting length, when the cumulative displacement reaches the set value, the sensor sends a signal to the controller 230 to trigger the cutting component to perform the cutting operation, thereby achieving accurate monitoring and control of the cutting length of the raw material. All of the above belong to the prior art.

[0022] In some embodiments: Electric linear actuator 310 and electric linear actuator 410 are both existing conventional technologies. The electric linear actuator mainly consists of a drive motor, reduction gear, screw, nut, guide sleeve, push rod, slide, spring, housing, turbine, micro-control switch, etc. Its working principle is as follows: After the motor starts, the output rotational power is reduced by the gear and drives the connected screw and nut assembly. The rotational motion of the motor is thus converted into linear motion. The extension and retraction of the push rod is achieved by the forward and reverse rotation of the motor. Common models on the market can be selected and need not be elaborated.

[0023] A lead screw motor 421 is fixedly connected to the outer wall of the movable frame 420. A lead screw is connected to the output end of the lead screw motor 421.

A connecting frame 431 is provided at the bottom of the movable block 430. A support shell 460 is fixedly connected to the outer wall of the connecting frame 431.

[0024] Specifically, a closed door 131 is connected to the front outer wall of the dust collection box 130 by a hinge. The outer wall of the closed door 131 is provided with bolts, and a corresponding threaded opening is opened on the outer wall of the dust collection box 130 to facilitate the closing and limiting of the closed door 131. A filter plate 132 is snapped into the inside of the dust collection box 130. A vacuum pump 133 is fixedly connected to the side wall of the dust collection box 130. The suction end of the vacuum pump 133 communicates with the inside of the dust collection box 130. Multiple suction pipes are also provided on the front outer wall of the dust collection box 130, and the multiple suction pipes communicate with the inside of the dust collection box 130.

[0025] In some embodiments, the dust pump 133 mainly consists of a motor, an impeller, and a volute, which facilitates the collection of debris generated during cutting.

[0026] Furthermore, a drive motor 221 is fixedly connected to the outer wall of the lifting frame 220, and a drive roller 222 is connected to the output end of the drive motor 221. A leveling roller 223 corresponding to the multiple leveling rollers 140 is also rotatably connected to the inner wall of the lifting frame 220, which facilitates the leveling of raw materials.

[0027] In some embodiments, the raw material is an unstamped aluminum alloy sheet. The drive motor 221 and the cutting motor used in this device are both existing technologies and need not be described in detail. Common models available on the market can be selected.

[0028] Furthermore, a cutting motor 432 is fixedly connected to the outer wall of the connecting frame 431, and a cutting blade 433 is connected to the output end of the cutting motor 432. A cavity 440 is opened inside the connecting frame 431, and a spring 441 is fixedly connected to the top of the inner cavity of the cavity 440. Multiple springs 441 are connected to telescopic frames 450 at their ends.

[0029] Furthermore, the telescopic frame 450 has an opening 451 on its outer wall, and a rotating roller 452 is rotatably connected to the bottom of the telescopic frame 450 to facilitate its movement on the surface of the raw material and avoid scratching.

[0030] It is worth noting that a dust collection box 461 is provided on the top of the support shell 460. The dust collection box 461 is connected to the inside of the support shell 460. The ends of multiple suction tubes are respectively connected to the outer wall of the dust collection box 461 and the collection shell 150 and extend into the inside of the dust collection box 461 and the collection shell 150.

[0031] It is worth noting that the inner wall of the support shell 460 has a cavity 470, and a spring 471 is fixedly connected to the top of the cavity 470. Multiple springs 471 are connected to telescopic frames 472 at their ends, and a rotating roller 473 is rotatably connected to the bottom of the telescopic frame 472.

[0032] In some embodiments, the device can be powered by an external power source, and the cut plates can be transferred and transported by an external belt conveyor to facilitate further processing. All of the above are existing technologies and need not be elaborated further.

[0033] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0034] Working Principle: During the actual cutting process, the raw material can be conveyed to the top of the collection shell 150 via the belt conveyor 120. At this time, the electric push rod 410 can be activated to drive the moving frame 420 to descend. Then, the cutting motor 432 can be activated to drive the cutting blade 433 to rotate. During the descent of the moving frame 420, the telescopic frame 450 and telescopic frame 472 inside the connecting frame 431 and support shell 460 of the cutting assembly can be adaptively adjusted by the plasticity of the springs 441 and 471, so that the debris generated during the descent and cutting process can still be blocked. After descending to the limit position, the screw motor 421 and the screw can drive the cutting assembly to move laterally, thereby cutting the raw material. During this cutting process, the generated debris can be removed from the top and bottom of the raw material by the action of multiple suction pipes. The material is drawn in and transferred to the dust collection box 130, where it is intercepted and collected by the filter plate 132. This reduces the difficulty in collecting metal debris and the safety hazards caused by high-speed splashing. When cutting after the moving frame 420 descends to its limit position, multiple rotating rollers 452 and 473 at the bottom of the telescopic frame 450 and telescopic frame 472, together with the top of the collection shell 150, can position and press down on the bottom of the raw material to ensure the accuracy of the cutting. Before the cutting process, when the raw material is introduced, the hydraulic lifting cylinder 210 can drive the lifting frame 220 to descend, and then the drive motor 221 drives the drive roller 222 to rotate, thereby pulling the raw material. During this process, multiple leveling rollers 140 and multiple leveling rollers 223 can level and adjust the flatness of the raw material to reduce its excessive bending, which would affect the subsequent cutting accuracy and the quality of the cut.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
