Description

Technical Field

[0001] This utility model relates to the field of tempered glass processing, and more specifically, to a laser cutting positioning fixture for tempered glass substrate. Background Technology

[0002] Currently, glass cutting is a fully automated operation. The cutting head, driven by the moving mechanism, cuts the outer contour of the glass. At the same time, the cutting head is raised and lowered by the Z-axis moving mechanism, and the cutting head is moved horizontally by the X and Y-axis moving mechanisms. In glass processing and manufacturing, glass needs to be cut, and the glass needs to be clamped and limited before cutting.

[0003] Because glass is prone to displacement during cutting, which can affect the accuracy of the cut and even damage the glass, people have set up clamping mechanisms, baffles, limiting plates and rollers to guide and clamp the glass, thereby ensuring the stability of the glass during cutting. For example, Chinese utility model patent with announcement number CN215855785U specifically discloses a positioning fixture for a multi-blade glass cutting machine.

[0004] However, in actual use, it is found that the above-mentioned glass cutting machine positioning fixture has the following characteristics: because the clamping mechanism clamps the glass from both sides, after the glass is cut, the cut parts will gradually separate and scatter as the glass is transported by the conveyor belt. This results in a lot of time being spent collecting the glass, thus reducing work efficiency. How to invent a solution to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a laser cutting positioning fixture for tempered glass substrate, which aims to improve the problem that the cut parts gradually separate and scatter, requiring a lot of time to collect the glass.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a laser cutting positioning fixture for tempered glass substrate, including a base, several first clamping plates, and a second clamping plate. Several legs are fixed on one side of the base, and a base plate and a sieve plate are respectively provided at both ends of the base. The base plate and the sieve plate are connected between the legs. A first cylinder is installed on the base plate. A support plate is rotatably connected to the base, and a slider is slidably connected to one side of the support plate. The output end of the first cylinder is rotatably connected to the slider. A bracket and a second cylinder are connected to the base, and a laser cutting machine is connected to the bracket. The first clamping plates are symmetrically arranged on both sides of the base. One side of the first clamping plate is connected to the output end of the second cylinder. A dual-axis motor is installed on the side of the first clamping plate away from the second cylinder. Both output shafts of the dual-axis motor are fixedly connected to lead screws, and one end of the second clamping plate is connected to the lead screws.

[0008] Preferably, the base has a through groove that extends longitudinally through the base, and the support plate is disposed inside the through groove; this facilitates the adjustment of the angle of the support plate on the base.

[0009] Preferably, a first groove is provided on the side of the first clamping plate away from the second cylinder, and the lead screw and the second clamping plate are both disposed inside the first groove, and the two sides of the second clamping plate are slidably connected to the first groove; this facilitates improving the stability of the second clamping plate sliding on the first clamping plate.

[0010] Preferably, the support plate has a second sliding groove laterally opened on the side near the base plate, and a guide rod is fixed inside the second sliding groove. The slider is slidably connected to the guide rod, which facilitates the cutting of the glass.

[0011] Preferably, a rotating shaft is fixedly connected to both sides of the support plate, and the end of the rotating shaft away from the support plate is rotatably connected to the base; this facilitates the fit of one end of the support plate with the sieve plate.

[0012] Preferably, a limiting plate is horizontally fixedly connected to the base, and the side of the support plate closest to the bottom plate is in contact with the limiting plate; this facilitates adjustment of the support plate for resetting.

[0013] The beneficial effects of this utility model are:

[0014] This laser cutting positioning fixture for tempered glass substrates uses a dual-axis motor mounted on a first clamping plate. Lead screws connected to the output ends of the motor on both sides control the movement of the second clamping plate, allowing for multi-angle positioning of the glass. This enables the glass to be clamped from multiple directions during laser cutting, improving the integrity of the glass after cutting and preventing it from scattering on the support plate. Furthermore, the fixture incorporates a base plate, a first cylinder, and a screen plate on the bottom surface of the base, allowing for adjustment of the support plate's angle. A slider slidably connects to the support plate, and the slider, in conjunction with the first cylinder, rotates one end of the support plate to fit against the screen plate. This facilitates the collection of cut glass, saving time and improving work efficiency.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example, refer to Figures 1-5 A laser cutting positioning fixture for tempered glass substrate includes a base 1, a plurality of first clamping plates 11 and second clamping plates 16;

[0024] Several support legs 2 are fixed on one side of the base 1. A base plate 3 and a sieve plate 5 are respectively installed at both ends of the base 1, with the base plate 3 and sieve plate 5 connected between the support legs 2. A first cylinder 4 is installed on the base plate 3. A support plate 6 is rotatably connected to the base 1, and a slider 19 is slidably connected to one side of the support plate 6. The output end of the first cylinder 4 is rotatably connected to the slider 19. A bracket 8 and a second cylinder 10 are connected to the base 1, and a laser cutting machine 9 is connected to the bracket 8. First clamping plates 11 are symmetrically arranged on both sides of the base 1. One side of the first clamping plate 11 is connected to the output end of the second cylinder 10. A dual-axis motor 14 is installed on the side of the first clamping plate 11 away from the second cylinder 10. Lead screws 15 are fixedly connected to the output shafts on both sides of the dual-axis motor 14. One end of the second clamping plate 16 is connected to the lead screw 15.

[0025] Furthermore, a through groove 12 is provided on the base 1, the through groove 12 extends longitudinally through the base 1, and the support plate 6 is disposed inside the through groove 12.

[0026] It should be noted that by placing the support plate 6 inside the through groove 12 opened on the base 1, space can be provided for the support plate 6 to rotate, making it convenient for the support plate 6 to adjust its angle on the base 1.

[0027] Furthermore, a first groove 13 is provided on the side of the first clamping plate 11 away from the second cylinder 10, and the lead screw 15 and the second clamping plate 16 are both disposed inside the first groove 13, and the two sides of the second clamping plate 16 are slidably connected to the first groove 13.

[0028] It should be noted that by opening a first groove 13 on one side of the first clamping plate 11, the sliding trajectory of the second clamping plate 16 can be guided in conjunction with the lead screw 15, which can improve the stability of the second clamping plate 16 sliding on the first clamping plate 11.

[0029] Furthermore, a second sliding groove 18 is provided laterally on the side of the support plate 6 near the bottom plate 3. A guide rod is fixed inside the second sliding groove 18, and the slider 19 is slidably connected to the guide rod.

[0030] It should be noted that by opening a second groove 18 on the support plate 6 to guide the sliding trajectory of the slider 19, the angle of the support plate 6 can be adjusted in conjunction with the extension and retraction of the first cylinder 4, making it easier for people to cut the glass.

[0031] Furthermore, a rotating shaft 17 is fixedly connected to both sides of the bearing plate 6, and the end of the rotating shaft 17 away from the bearing plate 6 is rotatably connected to the base 1.

[0032] It should be noted that by providing fixed connecting shafts 17 on both sides of the support plate 6, the support plate 6 can rotate on the base 1, which facilitates the fit of one end of the support plate 6 with the sieve plate 5.

[0033] Furthermore, a limiting plate 7 is horizontally fixedly connected to the base 1, and the side of the bearing plate 6 closest to the base plate 3 is in contact with the limiting plate 7.

[0034] It should be noted that by setting a limiting plate 7 on the base 1 and attaching it to the bottom surface of the support plate 6, the angle of the support plate 6 on the base 1 can be positioned, making it convenient for people to adjust the support plate 6 to reset.

[0035] The working principle of this laser cutting positioning fixture for tempered glass substrate is as follows: During use, the glass is placed on the support plate 6, and then the second cylinders 10 on both sides of the base 1 are activated, causing the second cylinders 10 to push the first clamping plate 11 towards the glass until the inner side of the first clamping plate 11 is in contact with the glass. Then, the dual-axis motor 14 installed on the first clamping plate 11 is activated, causing the lead screws 15 on both sides to control the second clamping plates 16 to move closer or further apart with the cooperation of the first sliding groove 13, until the second clamping plates 16 are in contact with the glass. At this time, the glass is restricted on both sides of the support plate 6. In this position, people control the laser cutter 9 on the support 8 to cut the glass. After the glass is cut, the first clamp 11 and the second clamp 16 are released from the glass. Then, the first cylinder 4 on the base plate 3 is activated to push the slider 19 to slide inside the second slide groove 18. Since the output end of the first cylinder 4 is rotatably connected to the slider 19, the support plate 6 will rotate clockwise inside the slide groove until one end of the support plate 6 is in contact with the screen plate 5 between the support leg 2. At this time, the cut glass will slide into the screen plate 5 along the angle of the horizontal plate, and the dust and particles will be separated from the glass.

[0036] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
