Description

Technical Field

[0001] This invention relates to the field of tablet computer processing technology, and in particular to a laser die-cutting machine for tablet computer processing. Background Technology

[0002] In the manufacturing process of tablet computers, panel materials need to be cut to high precision. Laser die-cutting technology, with its non-contact physical processing characteristics, is widely used in the forming and cutting process of various brittle or hard panels. This process mainly uses a high-energy beam to locally melt or vaporize the surface of the material on a support worktable to achieve precise physical separation of the panel outline.

[0003] A search of Chinese patent literature reveals that the authorized patent with publication number CN206188651U discloses a high-precision glass cutting machine. The equipment includes a frame, a cutting worktable fixed on the frame, a gantry slide rail structure, and a laser cutting head that is slidably connected to the gantry by the guide rail. It mainly relies on the basic support structure on the surface of the worktable to fix the panel, and uses a translation slide to drive the cutting head to run along a specified physical trajectory to complete the cutting action of the panel material.

[0004] The physical structure of existing technologies has obvious limitations in practical applications; their support platforms mostly use a single rigid support surface, which lacks flexible clearance space when the material undergoes local deformation due to heat, making it very easy to cause stress imbalance inside the panel and micro-cracks at the edges; the equipment lacks a fluid physical blocking and forced retraction mechanism around the cutting point, causing high-hardness dust to easily diffuse freely in the air and settle again on the panel surface; in addition, for finished products that are too tightly attached to the table surface after cutting, it lacks a bottom-up pure physical lifting and separation structure, and conventional external force forced peeling can easily cause secondary physical scratches or damage to the panel edges. Summary of the Invention

[0005] Technical problems to be solved To address the limitations of existing technologies, particularly the lack of flexibility in rigid load-bearing platforms when cutting large-area panels, leading to localized stress distortion; the lack of fluid physical barriers to prevent the micron-level high-hardness dust generated during laser cutting from escaping to the periphery and causing secondary scratches on the surface; and the fact that after cutting, the brittle panel is tightly bonded to the tabletop, and conventional external forced peeling easily causes edge micro-cracks and chipping, this invention provides a laser die-cutting machine for tablet computer processing.

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: A laser die-cutting machine for tablet computer processing includes: a die-cutting frame; a support plate, horizontally fixed to the top of the die-cutting frame for supporting a tablet computer panel to be cut; a transverse module A, fixedly installed on one side of the die-cutting frame; a transverse module B, one end of which is slidably mounted on the transverse module A, the transverse module B being cantilevered and suspended above the support plate; and a laser die-cutting module, slidably mounted on one side wall of the transverse module B for cutting the panel on the support plate under the drive of the transverse modules A and B.

[0007] Preferably, the transverse module A includes a side base fixed to one side of the die-cutting machine frame, and multiple guide rails A are provided on the top of the side base along its length direction. A sliding mounting seat A is slidably connected to the guide rails A. An electric drag chain A is also provided parallel to the side of the side base. A retractable corrugated protective cover is provided on the outside of the guide rails A. The end of the transverse module B is rigidly fixed to the sliding mounting seat A.

[0008] Preferably, the transverse module B includes a cantilever seat fixedly connected to the sliding mounting base A, and a guide rail B is provided on the side of the cantilever seat along its length direction. The sliding mounting base B is slidably connected to the guide rail B, and the laser die-cutting module is fixedly mounted on the sliding mounting base B.

[0009] Preferably, a flue gas treatment module is coaxially mounted on the bottom laser output end of the laser die-cutting module; the flue gas treatment module includes an outer cover, a middle partition cover, and an inner cover arranged in concentric circles.

[0010] Preferably, an air intake cavity is formed between the outer cover and the middle partition cover, and the cavity is connected to an external pumping pipe for downward jetting to blow away the fluid air curtain; a suction negative pressure cavity is formed between the middle partition cover and the inner cover, and the cavity is connected to a negative pressure pipe; the center of the inner cover is hollowed out to form a rigid physical channel through which the laser beam passes in a straight line.

[0011] Preferably, inside the die-cutting frame, a negative pressure suction module is suspended and installed directly below the support plate; the negative pressure suction module includes an air duct that runs horizontally through the inside of the die-cutting frame, the top of the air duct has multiple negative pressure absorption ports facing the bottom of the support plate, and one end of the air duct extends to the outside of the frame and is provided with a negative pressure connection port.

[0012] Preferably, a top material module is horizontally installed on one side of the die-cutting machine frame, below the support plate. The top material module is used to lift the panel from the bottom after cutting to achieve physical peeling and material discharge.

[0013] Preferably, the top material module includes a linkage cylinder fixed to the outer side of the die-cutting machine frame. The piston rod output end of the linkage cylinder is connected to a transverse linkage rod, and at least one follower rod is hinged to the linkage rod. A hinge seat is fixed on the die-cutting machine frame, and a rotating rod that penetrates into the machine frame is rotatably installed in the hinge seat. The outer end of the rotating rod is rigidly connected to the follower rod.

[0014] Preferably, the rotating rod has multiple arrayed top material columns fixed vertically along the axial direction, and the top of each top material column is inlaid with a top material ball to reduce physical contact friction; the bearing plate has clearance grooves that correspond one-to-one with the positions of the top material columns and are interconnected with each other.

[0015] Preferably, the bearing seat plate is a platform composed of multiple parallel and spaced metal support bars, and the clearance groove is opened on the edge side of the support bars; in the working state, the linkage cylinder extends linearly, pushes and pulls the follower rod through the linkage rod, drives the rotating rod to deflect, and causes the top material column to flip upward, so that the top material ball passes through the clearance groove from bottom to top and physically protrudes from the upper surface of the bearing seat plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention changes the traditional rigid large-area contact support method by setting a support plate composed of parallel spaced support bars, in conjunction with the negative pressure suction module below. When the panel is heated and deformed, it releases localized concentrated stress and suppresses the generation of micro-cracks at the edge of the panel.

[0017] By coaxially nesting a flue gas treatment module with external blowing and internal suction at the laser output end, a physical barrier wind wall is established around the cutting point using an annular laminar flow air curtain. Combined with a negative pressure chamber, the generated hard dust is instantly collected at the source, preventing the dust from spreading to the unprocessed area and avoiding physical scratches on the panel surface caused by secondary dust settling.

[0018] By configuring a pure-drive top-feeding module under the support plate, multiple top-feeding balls are driven through the clearance groove to smoothly lift the processed panel from bottom to top using a linkage cylinder and rotating rod. This achieves uniform physical separation between the formed panel and the support strip, replacing the conventional external force forced peeling and avoiding edge damage caused by the tight adhesion of materials during the handling and material handling process.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] like Figures 1 to 4 As shown, this embodiment of the invention provides a laser die-cutting machine for tablet computer processing. It mainly solves the problems of high-precision load-bearing, dust pollution prevention, and micro-cracks in the die-cutting process of large-area brittle panels through pure structural design and fluid physics control. The die-cutting machine mainly includes a basic support system, a two-dimensional coordinate translation system, a laser cutting and fluid dust removal system, and a bottom negative pressure adsorption and pure material ejection system.

[0023] The basic frame of the equipment is the die-cutting frame 1 at the bottom, which is welded from high-rigidity profiles; the top of the die-cutting frame 1 is horizontally fixed with a bearing plate 5; in order to reduce stress damage caused by the large-area rigid contact between the panel and the table, and to cooperate with the subsequent ejection action, the bearing plate 5 is spliced ​​together from multiple parallel spaced metal support strips (such as aluminum alloy strips with hard anodized surface treatment) to form a flat physical support surface with multiple gaps.

[0024] like Figure 3As shown, a negative pressure suction module 7 is suspended inside the die-cutting frame 1, directly below the support plate 5. The module includes a large-diameter air duct 71 that runs horizontally through the die-cutting frame 1. The outer end of the air duct 71 extends to the outside of the frame side plate to form a negative pressure connection port 73, which is used to connect to the factory's high-power vacuum pump. The top of the air duct 71 has multiple upward-facing negative pressure absorption ports 72. When cutting is performed, the external vacuum pump forms a uniform negative pressure zone between the support strips of the support plate 5. The atmospheric physical pressure difference is used to firmly and flatly adsorb and press the flat panel onto the support plate 5, avoiding slight warping and vibration displacement during processing.

[0025] To guide the laser head in precise trajectory movement within a two-dimensional plane, the equipment is equipped with a gantry-type slide structure consisting of a transverse module A2 and a transverse module B3. The transverse module A2 is arranged along the Y-axis of the equipment and mainly includes a side base 21 rigidly fixed to one side of the die-cutting frame 1. A high-precision guide rail A22 is laid on the top of the side base 21, and the sliding mounting seat A23 achieves low-friction sliding guidance with the guide rail A22 through the bottom slider. To prevent dust from falling into the guide rail and causing jamming, the guide rail A22 is covered with a retractable and foldable corrugated protective cover 25. At the same time, an electric drag chain A24 is installed parallel to the outer wall of the side base 21 to realize the physical storage and flexible guidance of the air tube, negative pressure pipeline and laser fiber. The transverse module B3 is arranged along the X-axis of the equipment, and is cantilevered and suspended above the bearing plate 5. One end of the cantilever 31 is rigidly anchored to the sliding mounting seat A23 by a flange and fastening bolts, so that the X-axis beam can move along the Y-axis base. The side of the cantilever 31 is provided with a guide rail B32, and the sliding mounting seat B33 that carries the cutting head is engaged with the guide rail B32 to achieve sliding in the X-axis direction.

[0026] like Figure 6As shown, to completely solve the problem of secondary settling and scratching of the panel surface by high-hardness micron-sized dust generated during laser cutting of brittle panels, a flue gas treatment module 8 based on fluid dynamics principles is coaxially nested at the bottom light outlet of the laser die-cutting module 4. The flue gas treatment module 8 consists of an outer cover 81, a middle partition cover 82, and an inner cover 83 arranged in concentric circles from the outside to the inside. The inner cover 83 has a hollow hole in the center, forming an unobstructed rigid physical channel for the laser beam to penetrate and focus on the panel surface. A closed air inlet cavity is formed between the walls of the outer cover 81 and the middle partition cover 82. The side of this cavity is connected to a pump pipe 85, which is connected to external constant-pressure clean gas. The pressurized gas is ejected at high speed from the lower annular slit between the inner and outer covers, forming a cylindrical laminar air curtain around the laser cutting point. The air pressure of the air curtain prevents the cutting dust from splashing to the outside. Meanwhile, an upward suction negative pressure chamber is formed between the middle partition 82 and the inner enclosure 83, with a negative pressure pipe 84 connected to its top. Within the physical enclosure of the cylindrical air curtain, the negative pressure suction chamber generates a powerful instantaneous back-pulling suction force directly above the cutting point. Utilizing the local physical airflow shearing effect, the newly generated dust and smoke are forcibly sucked upward. Through the fluid coordination of external blowing and internal suction, an extremely high standard of dust emission prevention is achieved.

[0027] like Figure 5 , Figure 7 As shown, after cutting is completed and the negative pressure suction is released, there is often micro-static adsorption or debris stuck between the brittle panel and the table surface. If manual forced removal is used, it is very easy to cause micro-cracks or even chipping and breaking of the panel edge. For this reason, the equipment is equipped with a top material module 6 for overall bottom support. The power source of the top material module 6 is a linkage cylinder 61 that is horizontally fixed on the front side plate of the die-cutting machine frame 1. The piston rod end of the linkage cylinder 61 is connected to a horizontally extending linkage rod 63, and a follower rod 62 is hinged to each end of the linkage rod 63. Two rotating rods 65 are inserted through the hinge seat 64 and supported by bearings on the front side plate of the die-cutting machine frame 1. One end of the rotating rod 65 extends out of the frame and is eccentrically rigidly connected to the corresponding follower rod 62, and the other end extends into the bearing seat plate 5 inside the frame. Several arrayed top material columns 66 are vertically welded to the rotating rod 65 along its central axis; to avoid rigid metal indentations during lifting, the top of the top material column 66 is inlaid with a top material ball 67 made of low friction material such as polytetrafluoroethylene; correspondingly, on the side wall of the multiple support bars of the bearing seat plate 5, at the spatial position corresponding to the top material column 66, there are through semi-circular clearance grooves 9.

[0028] Working principle and operation process: During processing preparation, the panel to be cut is laid flat on the support plate 5. The negative pressure suction module 7 works to use wind pressure to firmly adsorb the panel. Then, the transverse module A2 and transverse module B3 drag the laser die-cutting module 4 above the panel through the physical guide rail for cutting. At the same time as cutting, the flue gas treatment module 8 opens the air curtain to blow and the central negative pressure to draw back, physically peeling away and taking away the dust from the cut. After processing, the negative pressure suction module 7 releases pressure and air; the linkage cylinder 61 is inflated, causing the piston rod to extend linearly, pushing the linkage rod 63 to make a horizontal linear displacement; the linkage rod 63 drives the follower rod 62 to deflect at an angle, and then uses the lever principle to force the rotating rod 65 to rotate circumferentially within the hinge seat 64; the rotation of the rotating rod 65 causes the top material column 66, which was originally in a horizontal or inclined avoidance state, to flip upward, and the top material ball 67 passes through the avoidance groove 9 on the support bar from bottom to top, and finally physically protrudes from the support surface height of the bearing seat plate 5, applying a uniform thrust from the bottom of the panel, and smoothly lifting the cut panel as a whole, so that the panel is separated from the bearing seat plate 5, making it convenient for the next process to remove the material without damage.
