Description

Technical Field

[0001] The invention relates to the technical field of glass processing, and in particular to an anti-glare glass positioning and cutting device. Background Art

[0002] In order to ensure that the glass does not move during the cutting process, a clamping mechanism is generally provided in the traditional optical glass cutting device. The general clamping mechanism clamps and fixes the glass by the linear motion of the cylinder or the negative pressure adsorption of the suction cup, and then operates the cutting assembly for cutting. The clamping and cutting process is direct; and in its operation process, it is generally based on the scale bar pre-set on the fixture for positioning. Before clamping, the staff generally adjusts the position of the glass raw material with the scale bar by visual inspection, and then starts the equipment for clamping, and then cuts; however, due to the relatively low accuracy of manual visual inspection, if the position is found to be wrong after clamping, the cylinder clamping or suction cup clamping adopted by the existing equipment generally cannot be directly fine-tuned, and after releasing the clamping for adjustment, it needs to be re-clamped. In addition, the clamping process will also cause a certain position change. Combined with the trouble of adjusting the glass position, the clamping accuracy will be relatively low, and it needs to be trimmed twice later. The existing technology; secondly, during cutting, due to the high brittleness of the glass, the cutting knife directly contacts the glass rigidly, which can easily cause the glass to be stressed and the product to break, resulting in the loss of raw materials.

[0034] As a further configuration of the above scheme, the upper cutting toothed disc 3 and the lower cutting toothed disc 4 are both provided with a buffer cutting structure 6, a tool head fixture 33 and a cutting tool head 34, the tool head fixture 33 includes a hand crank 331, a threaded rod 332 fixed to the hand crank 331 and passing through the tool head fixture 33, the threaded rod 332 and the tool head fixture 33 are threadedly matched, one end of the threaded rod 332 passing through the tool head fixture 33 is also provided with a bayonet groove 333, and the end of the cutting tool head 34 is provided with a notch portion 341 matching the bayonet groove 333.

[0036] As a further arrangement of the above scheme, the buffer cutting structure 6 includes a mounting member 31 and a buffer spring 32. The upper cutting tooth disk 3 and the lower cutting tooth disk 4 are respectively provided with mounting cavities 30. The mounting member 31 is located in the mounting cavity 30. The tool head clamp 33 is sleeved in the inner hole of the mounting member 31. The two ends of the buffer spring 32 respectively abut against the inner walls of the tool head clamp 33 and the mounting member 31. A pressure gauge 38 is also provided at the other end of the buffer spring 32 that abuts against the tool head clamp 33. The pressure gauge 38 is used to display the pressure value of the cutting tool head 34 abutting against the glass surface. The mounting member 31 and the tool head clamp 33 are both provided with multi-edge grooves on the components covering the outer side thereof, thereby providing a circumferential limit arrangement.

[0037] The positioning and cutting device for anti-glare glass processing of the present invention has the following features: fast loading and unloading clamping, positioning and centering adjustment, double-sided uniform cutting, etc., wherein the device embodiment of the present invention includes a cutting disc frame 8 arranged on the device placement table 1 and a fast clamping structure 2 arranged thereon to achieve fast loading and unloading clamping, a double cutter disc is arranged to achieve double-sided uniform cutting, and a spacing shaft 83 is used to achieve super-center synchronous adjustment of both sides, etc.;

[0038] The cutting disc frame 8 is provided with a horizontal axis portion 81 and a longitudinal axis portion 82 in the horizontal direction, and the horizontal axis and the longitudinal axis tracks are used to realize that the horizontal axis 811 of the horizontal axis portion 81 rotates, so that the horizontal movable block 812 thereon generates horizontal movement along the axial direction of the horizontal axis 811 based on the threaded matching drive, and the longitudinal axis portion 82 at both ends of which is located on the horizontal movable block 812 and moves with the movement of the horizontal movable block 812 is similar. When the longitudinal axis 821 of the longitudinal axis portion 82 rotates, the longitudinal movable block 822 with threaded matching on the longitudinal axis 821 generates longitudinal horizontal movement, and the longitudinal movable block 822 is moved in any horizontal direction by the cooperation of the two. The rotation and process distance of the horizontal axis 811 and the longitudinal axis 821 can be controlled by the settings such as the driver 813 and the power piece 823.

[0039] Furthermore, the upper cutting toothed disk 3 and the lower cutting toothed disk 4 of the present embodiment integrate the structure of the components for cutting glass, which are arranged on the longitudinal movable block 822, and a flower axis 831 is also arranged in parallel on one side of the longitudinal axis 821, and the flower axis 831 belongs to the spacing axis portion 83. In addition to the flower axis 831, the spacing axis portion 83 is also provided with a rotating member 832 meshing with the flower axis 831 and a rack 834 fixed on the mounting member 31 arranged in the mounting cavity 30 on the upper cutting toothed disk 3 and the lower cutting toothed disk 4, and the rack 834 is meshed with the rotating member 832. Through the above-mentioned two-stage meshing, the rotation of the rotating member 832 is driven by the rotation of the flower axis 831, and the meshing drives the rack 834 to produce telescopic movement in the vertical direction. The structure is as follows Figure 6As shown, transmission meshing gears are set at both ends of the flower shaft 831 on a set of upper cutting tooth discs 3 and lower cutting tooth discs 4, so that the rotation directions of the two are opposite, so that under the drive of the power element, the two can rotate in opposite directions, and the driven rotating member 832 is meshed with the rack 834 in the opposite direction, so that the respective mounting parts 31 on the upper cutting tooth disc 3 and the lower cutting tooth disc 4 move closer to or away from the middle at the same time, thereby realizing the adjustment of the tool head clamps 33 on both sides of the glass processing to move closer to or away from the middle.

[0040] It is worth noting that when the cutting head 34 of the present invention is adjusted, the two-sided cutting heads are synchronously moved away and close, and a linkage structure is adopted on both sides to achieve automatic centering, without the need for staff to calibrate and fine-tune the two sides. As long as the equipment does not cause problems such as wear and damage, the cutting force applied on both sides can be guaranteed to be the same, and a pressure gauge 38 is provided for staff to observe and determine. In addition, the setting of the flower axis 831 of this embodiment is intended to be a structure of the flower axis 831, so that when the longitudinal movable block 822 moves axially along the longitudinal axis 821, the flower axis 831 and the rotating member 832 are in a radial meshing state, and do not interfere with the movable setting in the axial direction. In this process, the longitudinal axis 821 and the flower axis 831 are in a completely non-interference state in terms of activity. Therefore, when either of them is in motion, the rotation of the other axis will not be affected.

[0041] Furthermore, the cutter head fixture 33 of the present invention is also equipped with a buffer cutting structure 6. The buffer cutting structure 6 mainly includes a group of relatively strong buffer springs 32 at the end of the cutter head fixture 33, so that the cutting cutter head 34 has a certain elastic force when in use. Compared with the rigid cutting of the prior art, in this embodiment, when cutting, the buffer spring 32 will generate elastic compression to buffer the reaction force when the reaction force is too large, thereby reducing the material damage problem caused by the rigid cutting. Figure 5As shown, the buffer cutting structure 6 of the present embodiment includes a mounting part 31, and the mounting part 31 is sleeved on the outside of the tool head clamp 33, and the end of the tool head clamp 33 abuts the buffer spring 32, and the other end of the buffer spring 32 is installed with a pressure gauge 38 and abuts on the inner wall of the mounting part 31. The tool head clamp 33 itself and the mounting part 31 are circumferentially fixed and axially movable. The outer side surface of the tool head clamp 33 and the inner wall of the mounting part 31 can adopt structures such as protrusions, grooves, and edge grooves to achieve circumferential fixation and axial movement. The prior art application is not shown here. In addition, the tool head clamp 33 includes a threaded rod 332 and a hand-cranked part 331. The threaded rod 332 is threadedly matched with the threaded portion 336 of the inner wall of the tool head clamp 33. When the hand-cranked part 331 drives, the threaded rod 332 rotates circumferentially relative to the tool head clamp 33, and the axial movement of the tool head clamp 33 is achieved based on the threaded match, and the tool head clamp The lower end of the tool 33 is rotatably connected to a groove rod, and the lower end of the groove rod has a groove, which matches the notch portion 341 at the upper end of the cutting head 34. Through the setting of the block 343 and the notch 342 at the upper end of the cutting head 34, the threaded rod 332 is rotated based on the ginger, and it is axially tightened toward the deep inner hole of the head clamp 33, and the upper end of the block 343 abuts against the step surface 337 to maintain axial limit fixation. At this time, the rear end of the cutting head 34 is located on the inner side of the head clamp 33 and remains fixed in the axial and circumferential directions. The head clamp 33 realizes axial movable buffering with the mounting part 31 based on the buffer spring 32. Therefore, when in use, the cutting head 34 has a certain buffering force in the axial direction, and the setting of the pressure gauge 38 as mentioned above makes its reaction force during the cutting process clearly reflected on the pressure gauge 38, which can also facilitate the staff to record and observe.

[0042] Another design feature of the present invention is that the positioning and cutting device of the present invention can also quickly load and unload and clamp the glass raw materials when processing the glass raw materials. Its clamping characteristics include pre-clamping and center clamping. The function characteristic of the pre-clamping is that it can give the glass raw materials a pre-pressure before stable clamping so that it can maintain a stable placement effect, but its pressure clamping force is not enough to completely clamp the glass. At this time, the glass can also produce a certain translation adjustment, so as to adjust its position. After the adjustment is completed, it continues to be clamped to ensure the accuracy of clamping during processing. In addition, the characteristic of center clamping is that, as mentioned above, the present invention has a double-sided cutting device structure. When more glass raw materials are selected according to size and thickness, the quick clamping structure 2 set by the present invention is finally used to clamp the glass through the L-shaped clamps 21 on both sides. The center of the glass is always consistent, so that the distance between the cutting heads 34 on both sides and the glass is consistent, making the cutting process more perfect. Figure 2-4The quick clamping structure 2 of the present invention shown in FIG. 1 adopts an L-shaped clamp 21. Based on the external force, one of the two swing arms 211 hinged at the rear end thereof is driven to swing, thereby driving the L-shaped clamp 21 to swing eccentrically. It is worth noting that, as shown in FIG. Figure 4 As shown, of the two swing arms 211, one end of the swing arm 211 is hinged to the bracket and the L-shaped clamp 21 respectively, and the other end is hinged to the L-shaped clamp 21 at one end, and a gear member 29 is extended to the other end. Through the meshing transmission of the gear member 29, a group of L-shaped clamps 21 produce a shear-type clamping swing. Based on this design, the rotation shaft 23 of the L-shaped clamp 21 of this embodiment only needs any one of the two rotation shafts 23 to achieve clamping through the meshing linkage of the gear member 29. It is worth noting that in order to ensure the clamping and holding effect, the L-shaped clamp 21 of this embodiment can also be provided with a one-way ratchet 24 structure. The one-way ratchet 24 structure is basically based on the prior art. The design is used to limit the one-way rotation of the rotating shaft 23 of the L-shaped clamp 21, and a ratchet 25 with a traction rope 26 is provided. The one-way ratchet 24 is released by driving the traction rope 26 to pull the ratchet 25 to swing, so that the one-way ratchet 24 drives the rotating shaft 23 to rotate in the opposite direction based on the elastic restoring force of the reset coil spring 22, thereby releasing the drive to the L-shaped clamp 21 and releasing the clamping. The advantage of setting this structure is that the elastic restoring force of the reset coil spring 22 can realize the rapid release of the clamping of the glass. It is worth noting here that before releasing the clamping, the cut glass needs to be lifted and protected to avoid the glass falling and causing damage after the clamping is released;

[0043] The L-shaped clamp 21 is preferably a hollow glass with a spring 73 therein, and the hollow glass with a spring 73 therein is provided with a spring 74 therein so that the glass can be moved easily and precisely.

[0044] The positioning and cutting device of the present invention is designed to solve the multiple deficiencies of glass clamping, positioning, cutting and the like in the prior art by setting up multiple components. The quick clamping structure setting can improve the loading and unloading efficiency of processing, and the centered clamping brought about by it can also improve the quality of cutting effect. A double cutting toothed disc is set and a buffer cutting structure is used to assist in changing rigid contact cutting to flexible contact cutting, thereby reducing the loss of raw materials. The structural setting of the tool head clamp not only facilitates the loading and unloading and replacement of the cutting tool head, but the buffering effect of the structure not only solves the problem of rigid contact cutting, but is also less likely to cause loosening than the prior art. In addition, the L-shaped chuck provided in the embodiment of the present invention not only facilitates the principle of preventing clamping of the glass, but also the auxiliary positioning rod can realize pre-clamping of the glass, and convenient adjustment can be made during clamping, thereby improving the clamping accuracy.

[0045] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.

[0046] This specification and drawings are merely exemplary illustrations of the present application and are deemed to cover any and all modifications, variations, combinations or equivalents within the scope of the present application. Obviously, a person skilled in the art may make various modifications and variations to the present application without departing from the scope of the present application.
