Description

Technical Field

[0001] The invention belongs to the field of cutting technology, and in particular relates to a multi-angle cutting device for an outer frame of an LED display screen. Background Art

[0002] The outer frame of an LED display refers to the frame surrounding the LED display panel. It is typically used to secure and protect the display, and in many cases, it also serves as an aesthetic feature. The frame can be made of a variety of materials, such as aluminum alloy, stainless steel, or other metals, and sometimes non-metallic materials such as plastic or wood are also used. Cutting is a critical process step in the production of LED display frames. Precision cutting not only allows for customized dimensions to meet the technical specifications and installation requirements of different projects, but also improves material utilization, optimizes assembly efficiency, and enhances the product's functionality and aesthetics.

[0003] The traditional multi-angle cutting device for the outer frame of LED display screens generates a large amount of dust during the cutting operation. These dust particles are extremely small, light in weight and small in size. They can easily spread rapidly under the disturbance of air flow in the workshop or airflow generated by equipment operation. In a short period of time, the entire workshop will be filled with dust. Operators are in such an environment for a long time. The fine dust can easily be inhaled into the respiratory tract, which seriously threatens the health of their respiratory system and may cause symptoms such as coughing and asthma, or even serious occupational diseases such as pneumoconiosis, causing great damage to personal health. In addition, dust that is directly discharged into the external environment without effective treatment will pollute the atmosphere, increase the content of harmful particulate matter such as PM2.5, destroy the ecological balance, and bury potential risks for the sustainable development of the enterprise.

[0004] Therefore, a multi-angle cutting device for the outer frame of an LED display screen is particularly needed to solve the above problems. Summary of the Invention

[0016] The beneficial effects are as follows: 1. Through the synergistic effect of the first dust suction component and the second dust suction component, the dust generated by cutting can be fully sucked away. The dust suction hood promptly removes the dust around the placement plate, and the suction head handles the dust around the blade, thereby improving the working environment and reducing the health risks of operators. At the same time, the sucked dust is transported to external dust suction equipment and vacuum cleaners for centralized treatment, avoiding leakage and air pollution, meeting environmental protection requirements, and contributing to the green and sustainable development of enterprises.

[0017] Through the setting of the blowing component, gas is automatically ejected after cutting is completed to blow away the dust remaining on the surface of the placement plate. Combined with the dust suction component, more thorough cleaning is achieved, thereby improving the overall dust removal efficiency of the equipment and keeping the working area tidy.

[0018] 2. Through the linkage structure of the prismatic rod, fixed rod, knob, worm gear and worm, the operator only needs to rotate the fixed rod to achieve the synchronous rotation of the two bidirectional screws, thereby driving the synchronous movement of the clamping blocks to complete the clamping or loosening of the workpiece, avoiding manual adjustment one by one, and improving operation convenience and clamping stability.

[0019] 3. Through the cooperation of the fixed frame, pulley, connecting rod, limit block and top plate, the workpiece can be easily discharged after cutting. When the placement plate moves forward, the pulley slides into the high position of the slide, driving the connecting rod and the top plate to move upward, pushing the workpiece out of the placement plate, making it easier for the operator to remove the workpiece and improving work efficiency.

[0020] 4. Through the cooperation of connecting pipe 2 and dust collection cylinder, the cleaning effect after cutting is further improved. When the top plate rises and separates from the placement plate, the dust collection cylinder can suck away the dust falling from the contact gap between the placement plate and the top plate, ensuring that the placement plate is thoroughly cleaned and providing a good working environment for the next cutting.

The support frame 52 is bolted to the top of the placement plate 51, and the two sliding frames 53 are slidably arranged on the support frame 52. The internal thread of each sliding frame 53 is provided with a bidirectional screw rod 531. The front end of each bidirectional screw rod 531 extends to the outside of the sliding frame 53 and is provided with a torsion block for manual adjustment. The external thread of each bidirectional screw rod 531 is provided with two clamping blocks 532 symmetrically front and back. The four clamping blocks 532 correspond to the four sides of the placement plate 51 respectively. The two output shafts are respectively fixedly connected with a screw 55 through a coupling. The two sliding frames 53 are threadedly matched with the two screws 55, and the threads of the two screws 55 are in opposite directions, so that when the two output shafts of the dual-axis motor 54 drive the two screws 55 to rotate at the same time, the two sliding frames 53 can move inward or outward synchronously. The top bolt of each clamping block 532 is connected with a limit plate 56, and the four limit plates 56 also correspond to the four corners of the placement plate 51, so as to fully limit the workpiece.

[0041] like Figure 3 、 Figure 5 、 Figure 6 、 Figure 14 、 Figure 15 and Figure 16 As shown, the first dust suction assembly includes a dust suction hood 6, a dust suction pipe 61 and a filter plate 63. A dust suction hood 6 is bolted to the top of each sliding frame 53, and a dust suction pipe 61 is fixedly connected to the side of the two dust suction hoods 6 away from each other. The dust suction pipe 61 passes through the corresponding support plate 41, and its lower end not connected to the dust suction hood 6 is fixedly connected to the support plate 41, and the lower end is used to connect an external dust suction device. The dust suction pipe 61 is a corrugated tube that can be freely stretched to adapt to the movement requirements of the device. A filter plate 63 is bolted to the side of the two dust suction hoods 6 close to each other to prevent cutting debris from entering the dust suction pipe 61.

[0042] like Figure 3 、 Figure 6 and Figure 7 As shown, the second dust suction component includes a vacuum cleaner 7, an exhaust pipe 71 and a suction head 72. The vacuum cleaner 7 is bolted to the rear side of the protective frame 2, and two exhaust pipes 71 distributed on the left and right are fixedly connected to its top. The lower end of each exhaust pipe 71 is rotatably connected to the lower part of the rotating disc knife 47, and the exhaust pipe 71 is a corrugated pipe. A suction head 72 is fixedly connected to the lower end of each exhaust pipe 71, and the suction port of the suction head 72 is aligned with the blade 48 so as to promptly remove the dust generated during the cutting process.

[0043] like Figure 5 、 Figure 6 、 Figure 11 、 Figure 12 and Figure 13 As shown, the blowing assembly includes a baffle 49, a rack plate 9, a screw rod 91, a spur gear 92, a connecting pipe 93, an air jet head 94, a piston cylinder 95, a one-way pipe 951 and a piston plate 96. A row of neatly distributed openings 512 are respectively opened on the left and right sides of the placement plate 51. The two baffles 49 are horizontally distributed and welded on the table 4 along the left and right directions, and are embedded in the placement plate 51 to form a sliding fit therewith. The two baffles 49 block the two rows of openings 512 from the top direction respectively, and the top surface of the baffle 49 is kept flush with the top plate 84 of the placement plate 51 to ensure that the baffle 49 blocks the openings 512 in the shielding state. 12 does not affect the stable placement of the workpiece on the placement plate 51, the rack plate 9 is bolted to the bottom end of the table 4, the screw rod 91 is rotatably set at the bottom end of the placement plate 51, and forms a sliding fit with the table 4, the spur gear 92 is welded to the upper end of the screw rod 91, and is located on the left side of the rack plate 9 and meshes with it, two connecting pipes 93 are distributed and fixedly connected to the placement plate 51, each connecting pipe 93 is located on the pipe section inside the placement plate 51 and is fixedly connected to a row of neatly distributed nozzles 94, and the nozzles of each row of nozzles 94 are staggered upward and outward (i.e., from front to back The jet outlet of the first jet head 94 faces upward, the jet outlet of the second jet head 94 faces outward, and so on) to achieve multi-directional jetting, part of the pipe sections of the two connecting pipes 93 are extended to the inside of the base 1, a piston cylinder 95 is welded between the two pipe sections, the spiral part of the spiral rod 91 extends to the inside of the piston cylinder 95, and a one-way pipe 951 is welded to the lower end of the piston cylinder 95, so that the outside air enters the piston cylinder 95 in one direction through the one-way pipe 951, and the gas entering the piston cylinder 95 can only be discharged through the connecting pipe 93, and the piston plate 96 is threadedly arranged on the spiral rod 91. The outside of the rod 91 is located inside the piston cylinder 95 to form a sliding fit with it, and two grooves are opened on the surface of the screw rod 91. In the initial state, the piston plate 96 is in the lowest position of the first groove of the screw rod 91. As the screw rod 91 rotates, when the piston plate 96 moves to the highest position of the first groove, it will quickly and accurately enter the highest position of the second groove of the screw rod 91, and when it moves to the lowest position of the second groove, it will quickly and accurately enter the lowest position of the first groove of the screw rod 91. This cycle is repeated to form an up and down reciprocating motion of the piston plate 96.

[0044] like Figure 5 、 Figure 11 、 Figure 14 and Figure 17As shown, it also includes a fixing frame 8, a pulley 82, a connecting rod 83, a limit block 831 and a top plate 84. The fixing frame 8 is bolted to the inner upper part of the base 1, and a slide groove 81 is opened on both the left and right sides. Each slide groove 81 is divided into two parts, a high and a low part. A pulley 82 is slidingly arranged in each slide groove 81. The pulley 82 is located at the lower part of the slide groove 81. A connecting rod 83 is rotatably arranged on each pulley 82. The top plate 84 is welded between the top ends of the two connecting rods 83 and embedded in the center position of the placement plate 51. It forms a sliding contact with the placement plate 51, and the top surface of the top plate 84 remains flush with the top surface of the placement plate 51, ensuring that the existence of the top plate 84 does not affect the stable placement of the workpiece on the placement plate 51. A limit block 831 is welded to the upper end of each connecting rod 83, and the limit block 831 maintains a certain distance from the bottom end of the table 4. This distance is equal to the thickness of the top plate 84. When the connecting rod 83 moves up to the appropriate position, the top plate 84 is completely extended from the placement plate 51, and the limit block 831 just contacts the bottom end of the table 4 to limit the top plate 84.

[0045] like Figure 1 、 Figure 5 、 Figure 14 、 Figure 15 、 Figure 16 and Figure 17 As shown, it also includes a connecting pipe 2 10 and a dust collection cylinder 101. The lower end of each dust collection pipe 61 is fixedly connected to a connecting pipe 2 10, and the connecting pipe 2 10 is a corrugated pipe. The two dust collection cylinders 101 are bolted side by side and connected to the placement plate 51. The two connecting pipes 2 10 are respectively fixedly connected to the rear ends of the two dust collection cylinders 101. The left and right sides of the top plate 84 respectively contact the dust collection ports of the two dust collection cylinders 101, so that the dust collection cylinders 101 are in a sealed state. When the top plate 84 rises, its left and right sides are separated from the dust collection ports of the two dust collection cylinders 101. At this time, the dust collection cylinder 101 can suck away the dust that falls from the contact gap between the placement plate 51 and the top plate 84 when the top plate 84 is separated from the placement plate 51.

[0046] like Figure 6 、 Figure 8 、 Figure 9 and Figure 10 As shown, it also includes a prismatic rod 11, a fixed rod 111, a knob 112, a worm gear 113 and a worm 114. The two prismatic rods 11 are horizontally distributed in the left and right directions and welded on the front side of the placement plate 51. The fixed rod 111 is welded between the ends of the two prismatic rods 11 that are close to each other. The knob 112 is welded to the outside of the fixed rod 111. A worm gear 113 is welded to the front end of each bidirectional screw rod 531. A worm 114 is slidingly provided on the outside of each prismatic rod 11. The number of worm gears 113 and worm 114 is the same, and they are meshed one by one up and down. Based on the prismatic structure of the prismatic rod 11, the worm 114 can not only make a linear motion along the prismatic rod 11, but also drive the prismatic rod 11 to rotate together when rotating.

[0047] When a workpiece needs to be cut, the operator first connects the lower end of the dust collection tube 61 to an external dust collection device, then writes the preset cutting program into the controller 3, and then pulls the protective plate 21 outward in sequence to fully open the protective frame 2 to prepare for placing the workpiece;

[0048] When the program is started, the controller 3 starts the electric slide rail 4 5, controls the electric slider 4 511 to drive the placement plate 51 to move forward until the placement plate 51 passes the protective plate 21 and is outside the protective frame 2. At this time, the operator immediately places the workpiece to be cut on the placement plate 51, and the workpiece contacts the top plate 84. Then the dual-axis motor 54 is started, and its output shaft drives the screw 55 to rotate clockwise. Under the drive of the screw 55, the sliding frame 53 drives the clamping block 532 to move inward close to the workpiece. When the sliding frame 53 contacts the workpiece, the clamping block 532 moves inward close to the workpiece. When the workpiece is cut, the dual-axis motor 54 stops running. At this time, the operator holds the knob 112 and rotates the fixed rod 111 clockwise. The fixed rod 111 drives the prismatic rod 11 to rotate clockwise. The worm 114 rotates clockwise along with the prismatic rod 11 and meshes with the worm gear 113 in a positive direction. Under the drive of the worm 114, the worm gear 113 drives the bidirectional lead screw 531 to rotate counterclockwise. Under the drive of the bidirectional lead screw 531, the clamping block 532 moves inward synchronously to clamp the workpiece, ensuring that the workpiece will not be displaced during the cutting process.

[0049] After the clamping is completed, the controller 3 controls the electric slider 511 to drive the placement plate 51 to move backward until the placement plate 51 returns to the initial position. The operator pushes the protective plate 21 inward in sequence to completely close the protective frame 2 to provide a safe environment for the cutting operation.

[0050] Then, the electric slide rail 1 42, the electric slide rail 2 44 and the electric slide rail 3 45 are started, and the electric slider 1 43, the electric slider 2 441 and the electric slider 3 46 move the position of the rotary disc cutter 47 according to the preset program to make it reach the appropriate cutting position. During the movement, the rotary disc cutter 47 is started, and its cutter shaft drives the blade 48 to rotate and cut the workpiece. At the same time, the external dust collection device is operated, so that the dust collection pipe 61 and the dust collection hood 6 generate suction, and the dust collection hood 6 absorbs the dust generated during the cutting process. At the same time, the vacuum cleaner 7 is started, so that the exhaust pipe 71 generates suction, and the dust around the blade 48 is sucked away through the suction head 72, so as to keep the cutting environment clean.

[0051] After the cutting is completed, the rotating disc cutter 47 stops running and returns to the initial position. The operator immediately pulls out the protective plate 21 to open the protective frame 2 again, then holds the knob 112 to rotate the fixed rod 111 counterclockwise. The fixed rod 111 drives the prismatic rod 11 to rotate counterclockwise, and the worm 114 rotates counterclockwise along with the prismatic rod 11, meshing with the worm gear 113 in the opposite direction. Driven by the worm 114, the worm gear 113 drives the bidirectional lead screw 531 to rotate clockwise. Driven by the bidirectional lead screw 531, the clamping block 532 moves outward synchronously away from the workpiece. Then the dual-axis motor 54 is started again, and its output shaft drives the screw 55 to rotate counterclockwise. Driven by the screw 55, the sliding frame 53 drives the clamping block 532 to return to the initial position, and the dual-axis motor 54 stops running.

[0052] The controller 3 controls the electric slider 4 511 again to drive the placement plate 51 to move forward, so that the placement plate 51 is located outside the protective frame 2. When the placement plate 51 moves forward, it gradually disengages from the baffle 49, and the opening 512 is no longer blocked by the baffle 49. At the same time, the screw rod 91 moves forward together with the placement plate 51, so that the spur gear 92 is engaged with the rack plate 9. When engaged, the spur gear 92 drives the screw rod 91 to rotate, thereby driving the piston plate 96 to move upward. When the piston plate 96 moves, the piston cylinder 95 draws external air through the one-way tube 951. When the piston plate 96 moves up to the highest position of the screw rod 91, the piston plate 96 starts to move downward, squeezing the air in the piston cylinder 95 into the connecting pipe 1 93, and finally ejected from the nozzle 94. The ejected gas blows the dust remaining on the surface of the placement plate 51, which helps the dust hood 6 to more thoroughly absorb the dust and keep the placement plate 51 clean.

[0053] At the same time, the connecting rod 83 moves forward together with the placement plate 51, causing the pulley 82 to slide forward along the slide groove 81. When the pulley 82 slides into the high position of the slide groove 81, it drives the connecting rod 83 to move upward, and the top plate 84 moves upward together with the connecting rod 83, pushing the workpiece off the placement plate 51, making it easier for the operator to remove the workpiece. When the top plate 84 moves upward, it separates from the suction port of the dust collection cylinder 101. The dust collection pipe 61 is connected to the connecting pipe 10, so that the connecting pipe 10 generates suction, and then the dust collection cylinder 101 sucks away the dust that falls from the contact gap between the placement plate 51 and the top plate 84 when the top plate 84 separates from the placement plate 51, thereby further improving the cleaning effect.

[0054] When the placement plate 51 is completely outside the protective frame 2, the operator removes the workpiece that has been cut. Finally, the controller 3 controls the electric slider 511 again to drive the placement plate 51 to move backward, so that the placement plate 51 returns to its initial position. When the placement plate 51 moves backward, it gradually contacts the baffle 49, and the baffle 49 blocks the opening 512 again. At the same time, the screw rod 91 moves backward with the placement plate 51, so that the spur gear 92 continues to mesh with the rack plate 9. When meshing, the spur gear 92 continues to drive the screw rod 91 to rotate, thereby driving the piston plate 96 to reciprocate up and down. The nozzle 94 continues to spray gas to blow away the dust remaining on the surface of the placement plate 51.

[0055] At the same time, the connecting rod 83 moves backward along with the placement plate 51, causing the pulley 82 to slide backward along the slide groove 81. When the pulley 82 slides into the lower part of the slide groove 81, it drives the connecting rod 83 to move downward, and the top plate 84 moves down together with the connecting rod 83 to return to the initial position. When the top plate 84 moves down, it blocks the suction port of the dust collection tube 101, preparing for the next cutting.

[0056] If it is necessary to carry out the cutting operation of the next workpiece, when the placement plate 51 is completely withdrawn to the outside of the protective frame 2, the new workpiece can be placed on the placement plate 51, and then, the above-mentioned operation steps are carried out in sequence to achieve continuous cutting operation.
