Description

Technical Field

[0001] The invention belongs to the technical field of large screen template processing, and specifically relates to a constant linear speed turning processing device for processing large screen templates and a use method thereof. Background Art

[0002] The large-screen template is a basic model structure used for large-screen manufacturing or display. It is a design blueprint for the large screen. Just like the template in building construction, it stipulates the basic shape, size, installation structure and other key elements of the large screen.

[0003] When performing equal linear speed turning processing on the existing large-screen template, it is generally necessary to place the large-screen template on a turntable. Subsequently, the start, stop and movement speed of each power source need to be precisely controlled to complete a complete set of turning operations. For example, in some equipment, one power source may be used to loosen the clamp, another to flip the template, and another to re-clamp. The synchronization between these power sources is difficult to ensure, which easily leads to time differences. If the action of one power source is delayed, the template may be shifted during the flipping process, affecting the subsequent processing accuracy. At the same time, multiple power sources act in sequence to flip and fix the template, which will waste a lot of processing time, thereby affecting the turning efficiency. Therefore, an equal linear speed turning processing device and a method of use for processing large-screen templates are proposed to solve the problems raised in the background technology. Summary of the invention

[0009] The clamping assembly includes a gear plate, and clamping blocks are movably connected around the inside of the square plate;

[0010] A guide groove is provided on the surface of the gear plate, and a convex rod is fixedly connected to the top of one end of the clamping block, and the convex rod is movably clamped in the guide groove;

[0011] The limit block passes through the outer wall of the workbench and extends to the outside of the workbench. A limit groove is provided on one side of the top of the limit block. A clamping block movably clamped in the limit groove is provided on one side of the cutting edge.

[0012] The outer wall of the sliding block is provided with a protrusion, and the protrusion is located at the top of the first arc groove in the initial state;

[0013] The upper and lower ends of the first arc groove are respectively connected to the two ends of the second arc groove, the arc of the first arc groove is thirty degrees, and the arc of the second arc groove is three hundred and thirty degrees;

[0014] When the slider moves downward, the projection drives the drum to rotate 30 degrees clockwise along the trajectory of the first arc groove, and when the slider moves upward, the projection drives the drum to rotate 330 degrees clockwise along the trajectory of the second arc groove;

[0015] A round rod is fixedly connected to the bottom of the rotating drum. When the rotating drum rotates, the round rod is driven to slide into the interior of the slide groove. After the rotating drum rotates one circle, the cooperation between the round rod and the slide groove drives the rotating shaft to rotate ninety degrees.

[0016] Preferably, a gasket is provided on the top of the clamping block, and the gasket is made of rubber material. A tooth plate meshing with the gear plate is movably connected inside the square plate.

[0017] Preferably, one end of the tooth plate is fixedly connected to a pull rod, which consists of two round rods and a handle located outside the square plate. A spring is sleeved on the outside of the round rod of the pull rod, and both ends of the spring are fixedly connected to the tooth plate and the square plate respectively.

[0018] Preferably, the adsorption assembly includes a vacuum pump fixedly connected to the inside of the workbench, a suction cup is fixedly connected to the inside of the rotating shaft, and a vacuum suction pipe connected to the vacuum pump is movably connected to the bottom end of the suction cup;

[0019] The suction cup penetrates the outer wall of the rotating assembly and the square plate and extends to the outside of the square plate, and a gap is left between the top of the suction cup and the top of the square plate.

[0020] The present application also proposes a method for machining a large screen template using a constant linear speed turning method, the method steps are as follows:

[0021] S1. Place the large screen template on the adsorption assembly, and pull the toothed plate with the gear plate to rotate, so that the convex rod drives the clamping block to move toward the square plate along the track of the guide groove, so that the four gaskets are all in contact with the outer wall of the large screen and exert a squeezing force, so as to correct the position of the large screen template;

[0022] S2. The vacuum pump forms a negative pressure state on the top of the suction cup through the vacuum suction tube, thereby fixing the calibrated large screen template, and then drives the motor in the assembly to run, thereby accurately adjusting the position and speed of the cutting edge;

[0023] S3. After the cutting edge drives the limit block and the slider at the bottom thereof to move up and down once, the slider drives the rotating drum to rotate one circle by cooperating with the first arc groove and the second arc groove, so that the round rod slides into the interior of the slide groove, and drives the adsorption component inside the rotating shaft to rotate ninety degrees through the special-shaped disk, so as to perform turning operations on the other sides of the large screen template.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention improves the turning efficiency through the coordination between structures such as the moving component, the rotating component and the adsorption component. The two ends of the first arc groove are respectively connected with the two ends of the second arc groove, so that the cutting edge drives the slider to move up and down reciprocatingly once through the limit block, and the protrusion on the slider can slide along the trajectory of the first arc groove to the inside of the second arc groove, and drive the rotating cylinder and the round rod at the bottom thereof to rotate one circle through the second arc groove. After the rotation of the round rod, it can slide into the inside of the slide groove, and then drive the rotating shaft to rotate ninety degrees. The suction cup is fixedly connected to the rotating shaft, so that when the special-shaped disk drives the rotating shaft to rotate, the suction cup can drive the large screen template fixed on it to rotate ninety degrees. After the cutting edge reciprocates four times, it is convenient to perform turning operations on the four sides of the large screen template, thereby improving the turning efficiency.

[0026] The present invention facilitates the correction of the initial position of the large-screen template through the coordination between structures such as the gear plate, the clamping block and the tooth plate, thereby improving the turning accuracy. The gear plate is meshed with the tooth plate, so that the tooth plate can drive the gear plate to rotate when it moves, and then the convex rod drives the clamping block to move toward the square plate along the trajectory of the guide groove. After the four clamping blocks move, they all drive the gasket to abut against the outer wall of the large-screen template, thereby applying the same thrust to the four sides of the outer wall of the large-screen template, so that the non-vertical edge is rotated until it reaches a vertical state, thereby improving the processing accuracy of subsequent turning operations.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 6 As shown, the present invention provides a constant linear speed turning device for processing a large screen template, comprising a workbench 1, a driving component 2 is arranged on the top of the workbench 1, a cutting edge 3 is slidably connected to the driving component 2, and a moving component 4 and a rotating component 5 are movably connected inside the workbench 1;

[0036] The rotating assembly 5 includes a rotating shaft 51, a special-shaped disc 52 is fixedly connected to the outside of the rotating shaft 51, and sliding grooves 53 are provided at the four corners of the rotating shaft 51;

[0037] An adsorption assembly 6 is provided inside the workbench 1, a square plate 7 is fixedly connected to the top of the rotating shaft 51, and a clamping assembly 8 is movably connected inside the square plate 7;

[0038] The moving assembly 4 includes a rotating drum 41, the inner wall of which is provided with a first arc groove 42 and a second arc groove 43, the interior of the rotating drum 41 is movably connected with a slider 45, and the top end of the slider 45 is fixedly connected with a limit block 46;

[0039] The clamping assembly 8 includes a gear plate 81, and clamping blocks 83 are movably connected to the four sides of the square plate 7;

[0040] A guide groove 82 is formed on the surface of the gear plate 81, and a protruding rod 84 is fixedly connected to the top of one end of the clamping block 83, and the protruding rod 84 is movably engaged in the inner part of the guide groove 82;

[0041] The limit block 46 passes through the outer wall of the workbench 1 and extends to the outside of the workbench 1. A limit groove is provided on one side of the top of the limit block 46. A clamping block movably clamped in the limit groove is provided on one side of the cutting edge 3.

[0042] The outer wall of the slider 45 is provided with a protrusion, which is located at the top of the first arc groove 42 in the initial state;

[0043] The upper and lower ends of the first arc groove 42 are respectively connected to the two ends of the second arc groove 43. The arc of the first arc groove 42 is thirty degrees, and the arc of the second arc groove 43 is three hundred and thirty degrees.

[0044] When the slider 45 moves downward, the projection drives the drum 41 to rotate 30 degrees clockwise along the track of the first arc groove 42 . When the slider 45 moves upward, the projection drives the drum 41 to rotate 330 degrees clockwise along the track of the second arc groove 43 .

[0045] A round rod 44 is fixedly connected to the bottom of the rotating drum 41. When the rotating drum 41 rotates, the round rod 44 is driven to slide into the interior of the slide groove 53. After the rotating drum 41 rotates one circle, the cooperation between the round rod 44 and the slide groove 53 drives the rotating shaft 51 to rotate ninety degrees.

[0046] The above scheme is adopted: the two ends of the first arc groove 42 are respectively connected with the two ends of the second arc groove 43, so that the cutting edge 3 drives the slider 45 to move up and down reciprocatingly once through the limit block 46, and the protrusion on the slider 45 can slide along the trajectory of the first arc groove 42 to the inside of the second arc groove 43, and drive the rotating cylinder 41 and the round rod 44 at the bottom thereof to rotate one circle through the second arc groove 43, and after the round rod 44 rotates, it can slide into the inside of the slide groove 53, and then drive the rotating shaft 51 to rotate ninety degrees, and is fixedly connected to the rotating shaft 51 through the suction cup 63, so that when the special-shaped disk 52 drives the rotating shaft 51 to rotate, it can drive the large screen template fixed thereon to rotate ninety degrees through the suction cup 63, and after the cutting edge 3 reciprocates four times, it is convenient to perform turning operations on the four sides of the large screen template, thereby improving the turning processing efficiency;

[0047] The above scheme is adopted: a limit groove is opened on the limit block 46, and its function is that when the motor in the driving component 2 drives the cutting edge 3 to move axially or longitudinally, the block on one side of the cutting edge 3 will slide inside the limit groove, thereby ensuring the normal operation of the device.

[0048] like Figure 3 and Figure 6 As shown, a gasket 85 is arranged on the top of the clamping block 83, and the gasket 85 is made of rubber material. The inside of the square plate 7 is movably connected with a tooth plate 86 meshing with the gear plate 81, and one end of the tooth plate 86 is fixedly connected with a pull rod 87, and the pull rod 87 is composed of two round rods and a handle located outside the square plate 7. The outer sleeve of the round rod of the pull rod 87 is provided with a spring 88, and the two ends of the spring 88 are respectively fixedly connected to the tooth plate 86 and the square plate 7.

[0049] The above solution is adopted: the gasket 85 is made of rubber material. Its function is that since the large-screen template usually has high surface accuracy and quality requirements, its surface may be smooth glass, high-precision metal or plastic coating and other fragile materials, and the rubber material is soft in texture. When it comes into contact with the template surface, it can avoid directly scratching the template surface like metal or hard plastic push blocks.

[0050] like Figure 2 and Figure 4 As shown, the adsorption component 6 includes a vacuum pump 61 fixedly connected to the inside of the workbench 1, a suction cup 63 is fixedly connected to the inside of the rotating shaft 51, and the bottom end of the suction cup 63 is movably connected to a vacuum suction pipe 62 connected to the vacuum pump 61, and the suction cup 63 passes through the outer wall of the rotating component 5 and the square plate 7, and extends to the outside of the square plate 7, leaving a gap between the top of the suction cup 63 and the top of the square plate 7.

[0051] The above scheme is adopted: a gap is left between the top of the suction cup 63 and the top of the square plate 7. The purpose of leaving the gap is that it is not only conducive to the natural falling of debris and dust generated by turning, but also makes the subsequent cleaning work more convenient. At the same time, during the turning process, the cutter needs to perform cutting action on the surface of the large-screen template, and leaving a gap can prevent the bottom of the cutter from colliding and rubbing with the top of the square plate 7.

[0052] The working principle and use process of the present invention are as follows: the operator places the square screen template on the adsorption component 6, and then pulls the pull rod 87 to drive the tooth plate 86 to move in the direction of the spring 88, and then the tooth plate 86 is meshed and connected with the gear plate 81, thereby driving the gear plate 81 to rotate. While the gear plate 81 rotates, it drives the protruding rod 84 to slide along the trajectory of the guide groove 82, thereby driving the clamping block 83 to move in the direction of the adsorption component 6 through the protruding rod 84. When the clamping block 83 drives the gasket 85 to abut against the outer wall of the large screen template, at this time, the four gaskets 85 all apply thrust to the large screen template, thereby correcting the position of the large screen template, so that the center point of the large screen template is located directly above the adsorption component 6;

[0053] Subsequently, the operator issues a start command to the vacuum pump 61 through the remote control panel, thereby causing the working medium in the vacuum pump 61 to move, and forms a negative pressure on the top of the suction cup 63 through the vacuum suction pipe 62, thereby causing the large screen template to be tightly adsorbed on the top of the suction cup 63. Subsequently, the operator releases the pull on the pull rod 87, thereby causing the tooth plate 86 to reset under the action of the elastic force of the spring 88, thereby driving the gear plate 81 to rotate in the opposite direction, and subsequently, the protruding rod 84 drives the clamping block 83 to move in the opposite direction along the trajectory of the guide groove 82 to reset, thereby releasing the abutment against the outer side of the large screen template.

[0054] When the large screen template is fixed by the adsorption component 6, at this time, the feed motor in the driving component 2 needs to accurately control the feed speed and position of the cutting edge 3. When the cutting edge 3 moves to the position where the outer contour of the large screen template needs to be turned, at this time, the longitudinal feed motor controls the cutting edge 3 to move along the axial direction of the workpiece according to a predetermined program, and at the same time, the transverse feed motor adjusts the cutting depth of the tool in time according to the shape and size requirements of the template, so that the cutting edge 3 can accurately turn one side of the outer screen template on the adsorption component 6. When the cutting edge 3 moves downward, it will drive the limit block 46 and the slider 45 at its bottom to move downward through the block on one side, so that the protrusion on the slider 45 slides along the trajectory of the first arc groove 42, thereby driving the rotating drum 41 to rotate thirty degrees clockwise;

[0055] When the cutting edge 3 has completed turning one side of the screen template, the cutting edge 3 drives the limit block 46 and the slider 45 to move up through the protrusion, so that the protrusion on the slider 45 slides along the trajectory of the second arc groove 43, and then the rotating drum 41 rotates three hundred and thirty degrees clockwise. While rotating, the rotating drum 41 will drive the round rod 44 to slide into the interior of the slide groove 53, thereby driving the special-shaped disk 52 to rotate together through the slide groove 53. After the round rod 44 drives the special-shaped disk 52 to rotate ninety degrees through the slide groove 53, it will slide out of the slide groove 53. While the special-shaped disk 52 rotates, it drives the suction cup 63 inside it to rotate through the rotating shaft 51, and then the suction cup 63 drives the large screen template fixed on it to rotate ninety degrees. This operation is repeated. After the cutting edge 3 reciprocates the assembly four times, it is convenient to turn the four sides of the large screen template, thereby improving the turning efficiency.
