Description

Technical Field

[0001] The invention relates to the technical field of glass cutting, and in particular to a laser device for glass cutting. Background Art

[0002] Because the edges of laser-cut glass are smooth and bright without jagged lines, and no fire polishing is required during the cutting process, the subsequent processing steps are reduced. The laser tubes used in laser cutting equipment are of excellent quality, stable performance, and have extremely high positioning accuracy and repeatability. The processing accuracy can reach 0.02 mm, which enables laser cutting to meet the processing needs of complex graphics and fine parts, such as the cutting of glass components for precision electronic products such as mobile phone screens and tablet computer screens.

[0003] China Patent Network has published a publication number: CN116282873B, named a liquid crystal glass substrate laser cutting device. The support mechanism used cooperates with the transmission mechanism, the drive mechanism and the connecting ring to support the glass substrate. After the glass substrate is cut, the support position of the support mechanism is changed to achieve the function of quickly separating the cut glass substrate, which is convenient for taking the required glass substrate after cutting.

[0004] In the above-mentioned public documents, when cutting glass products, the objects to be cut are all larger glass products, such as glass table tops, window glass, etc. As for small glass products or when cutting multiple glass products from the same piece of glass, such as goggles glass, small dressing mirrors, etc., it is not possible to quickly separate the cut glass products and glass fragments. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a laser device for glass cutting, which can effectively solve the problem of rapid separation of glass products and broken materials when cutting small glass products in the prior art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The present invention provides a laser device for glass cutting, comprising a workbench, a laser module is arranged on the workbench, and further comprising:

[0008] A support frame is arranged in the workbench, on which a guide rod 1 and a guide rod 2 which are vertically distributed to each other are slidably mounted, and the guide rod 1 is located above the guide rod 2, and the support frame also includes a movable table which is slidably connected to the guide rod 1 and the guide rod 2 respectively;

[0009] A suction member for adsorbing glass is arranged on the movable platform, the suction member comprises a fixed column with an air cavity, a mounting sleeve and an air inlet pipe for exhausting air, a fixed frame and a push platform slidably mounted on the fixed frame are arranged in the fixed column, and an elastic member is arranged between the fixed frame and the push platform, the elastic member is used to always push the push platform out of the fixed column, a movable column is arranged between the push platform and the fixed frame to reduce the extension speed of the push platform, a rotating rod is rotatably mounted on the mounting sleeve, and adjacent fixed columns are rotatably connected through the rotating rod;

[0010] And a driving bar 1 and a driving bar 2 for driving the rotating rod, wherein the driving bar 1 and the driving bar 2 are perpendicular to each other in the same horizontal plane.

[0011] Furthermore, guide groove 1 is provided on both sides of the support frame in the transverse direction, and guide groove 2 is provided on both sides of the support frame in the longitudinal direction. Guide groove 1 and guide groove 2 are offset from each other in the vertical direction, and guide groove 1 is higher than guide groove 2.

[0012] Furthermore, the guide rod one and the guide rod two are each provided with multiple groups, and the movable platform is located at the intersection of the guide rod one and the guide rod two, and the multiple groups of movable platforms cooperate to achieve simultaneous movement of multiple groups of suction members.

[0013] Furthermore, the rotating rods on the mounting sleeve are provided with four groups and distributed in a circular array, and one end of the rotating rod away from the mounting sleeve is rotatably connected to the rotating rod on the adjacent suction member through a rotating shaft, and the driving bar 1 and the driving bar 2 are both connected to the rotating shaft through a bracket, and the height of the bracket on the driving bar 2 is greater than the height of the bracket on the driving bar 1, so as to prevent the driving bar 1 and the driving bar 2 from interfering with each other when they drive the rotating rods respectively.

[0014] Furthermore, two groups of driving cylinders are provided on the workbench, and the driving ends of the two groups of driving cylinders are respectively connected to driving bar one and driving bar two. When driving bar one rises, the angle between two adjacent groups of rotating rods in the transverse direction gradually increases, thereby pushing the suction members and the movable platform away from each other and increasing the transverse distance between adjacent suction members. When driving bar two rises, the angle between two adjacent groups of rotating rods in the longitudinal direction increases, thereby pushing the suction members and the movable platform away from each other and increasing the longitudinal distance between adjacent suction members. Conversely, the transverse distance and the longitudinal distance between the suction members are reduced.

[0015] Furthermore, the push platform is provided with balls and multiple groups of air inlet grooves, and a movable column is provided at the bottom of the push platform, the diameter of the movable column is smaller than the diameter of the air cavity, a spiral groove is provided in the fixed column, and a guide column extending into the spiral groove is provided on the movable column.

[0016] Furthermore, an annular groove with a diameter larger than the air cavity is provided in the fixed column. When the air inlet pipe draws gas from the fixed column and pulls the push platform down to the annular groove, the ball retracts into the fixed column, and at the same time, the air inlet groove is connected with the air cavity, so that the glass is adsorbed on the top of the fixed column.

[0017] Furthermore, a valve is provided between the air intake pipe and the fixed column, and a switch is provided in the fixed column to resist the guide column. When the guide column moves partially and moves away from the switch, the switch opens the valve between the air intake pipe and the fixed column.

[0018] Furthermore, the workbench is composed of a lower shell and an upper shell, and the support frame is located between the lower shell and the upper shell, a material guide hopper is provided on the side of the lower shell away from the support frame, and an air supply part is provided on the side of the upper shell away from the support frame. The laser module is set on the workbench through a driving bracket, and the driving bracket is used to drive the laser module to move to cooperate with glass cutting. Beneficial Effects

[0019] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0020] 1. By cutting the area of ​​the finished glass product as needed, the driving bar 1 and the driving bar 2 are driven to rise and fall, so as to change the density of the fixed columns, and at least four groups of fixed columns are maintained to support the finished glass product. The gas in the fixed columns is extracted with the gas supply part and the air inlet pipe to fix the glass. After the processing is completed, the glass fragments are separated from the finished glass product by canceling the adsorption of the glass, and the push platform is used to separate the finished glass fragments quickly;

[0021] Second, after the push table rises, the ball bearings are used to reduce the support area, which helps the glass fragments to fall and separate quickly. At the same time, the movable column and the spiral groove are used to reduce the speed of the push table to prevent the push table from rising too fast and damaging the glass. At the same time, it can prevent the finished glass from being ejected after processing, thus protecting the glass.

[0022] 3. Through the cooperation of the guide column on the movable column and the switch, the fixed column that is not in contact with the glass is not squeezed, and the guide column is in the upper limit position, thereby squeezing the switch to close the valve on the air inlet pipe, and the fixed column supporting the finished glass opens the corresponding valve on the air inlet pipe, which solves the problem of fixing the finished glass again after the glass fragments are separated, making it easy to take out.

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0034] The present invention will be further described below in conjunction with the embodiments. Example

[0035] A laser device for glass cutting, see attached Figure 1-8 , including a workbench 1, on which a laser module 14 is disposed, the laser module 14 is disposed on the workbench 1 through a driving bracket, and the driving bracket is used to drive the laser module 14 to move in the X-axis, Y-axis and Z-axis directions to cooperate with the cutting of the glass, and also includes:

[0036] A support frame 13 is arranged in the workbench 1, and the workbench 1 is composed of a lower shell 11 and an upper shell 12, and the support frame 13 is located between the lower shell 11 and the upper shell 12, a guide hopper 111 is provided on the side of the lower shell 11 away from the support frame 13, and an air supply member 121 is provided on the side of the upper shell 12 away from the support frame 13, the guide hopper 111 is used to provide adsorption force for the fixed glass, and the air supply member 121 is used to guide the glass fragments to the collection box for centralized collection, and a guide rod 131 and a guide rod 2 132 are slidably installed on the support frame 13, and the guide rod 1 131 and the guide rod 2 132 are perpendicular to each other in a top view, and the guide rod 1 131 is located above the guide rod 2 132, and a height difference is provided between the guide rod 1 131 and the guide rod 2 132 to prevent the guide rod 1 131 and the guide rod 2 132 from interfering with each other when moving, and the support frame 13 also includes a movable platform 133 slidably connected to the guide rod 1 131 and the guide rod 2 132 respectively.

[0037] Specifically, guide groove 1301 is provided on both sides of the support frame 13 in the horizontal direction, and guide groove 2 1302 is provided on both sides of the support frame 13 in the longitudinal direction. Guide groove 1301 and guide groove 2 1302 are offset from each other in the vertical direction, and guide groove 1301 is higher than guide groove 2 1302. Both ends of guide rod 1 131 are inserted in guide groove 1 1301, and both ends of guide rod 2 132 are inserted in guide groove 2 1302.

[0038] Furthermore, the guide rod 1 131 and the guide rod 2 132 are each provided with multiple groups, and the movable platform 133 is located at the intersection of the guide rod 1 131 and the guide rod 2 132 , and the multiple groups of movable platforms 133 cooperate to achieve simultaneous movement of multiple groups of suction members 2 .

[0039] A suction member 2 for adsorbing glass is arranged on the movable platform 133, and the suction member 2 includes a fixed column 21 provided with an air cavity 2101, the fixed column 21 is used to support the glass, and the air cavity 2101 is used to draw air to adsorb the glass, so that the glass is fixed more stably, and the mounting sleeve 22 is fixedly arranged on the outer periphery of the fixed column 21, and one end of the air inlet pipe 24 is arranged on the air supply member 121, and the other end is arranged on the fixed column 21 and communicated with the air cavity 2101, and the air inlet pipe 24 is an annular pipe, which can cooperate with the movement of the fixed column 21 to prevent affecting the normal movement of the fixed column 21, and a fixed frame 211 and a push platform 212 slidably installed on the fixed frame 211 are arranged in the fixed column 21, and the push platform 212 and the fixed column 2 1 is in contact with the inner wall of the fixed column 21, similar to a piston disk. When the air inlet pipe 24 extracts the gas in the fixed column 21, the push platform 212 is pulled down, and an elastic member 214 is provided between the fixed frame 211 and the push platform 212. The elastic member 214 is used to always push the push platform 212 out of the fixed column 21. When the air inlet pipe 24 stops extracting the gas in the air cavity 2101, the push platform 212 will extend out of the fixed column 21 when the elastic member 214 is reset. When the push platform 212 is extended quickly, it is easy to hit the glass and cause it to be damaged. Therefore, a movable column 213 for reducing the extension speed of the push platform 212 is provided between the push platform 212 and the fixed frame 211 to slow down the speed of the push platform 212 extending out of the fixed column 21 and protect the glass.

[0040] Among them, the push platform 212 is provided with a ball 2121 and a plurality of air inlet grooves 2122. The ball 2121 is used to reduce the friction between the fixed column 21 and the glass when it moves after supporting the glass to prevent scratching the glass. The air inlet groove 2122 is used to connect the outside and the air cavity 2101 after the push platform 212 descends to a certain position. A movable column 213 is provided at the bottom of the push platform 212. The diameter of the movable column 213 is smaller than the diameter of the air cavity 2101 to facilitate the circulation of gas. A spiral groove 2103 is provided in the fixed column 21, and a guide column 2131 extending into the spiral groove 2103 is provided on the movable column 213. Through the guidance of the spiral groove 2103, the speed at which the glass contacts the fixed column 21 during adsorption and the speed at which the push platform 212 extends out of the fixed column 21 are reduced, thereby protecting the glass.

[0041] In addition, an annular groove 2102 with a diameter larger than the air cavity 2101 is provided in the fixed column 21. When the air inlet pipe 24 extracts the gas in the fixed column 21 and pulls the push platform 212 down to the annular groove 2102, the ball 2121 retracts into the fixed column 21. At the same time, the air inlet groove 2122 is connected to the air cavity 2101, so that the glass is adsorbed on the top of the fixed column 21.

[0042] In addition, a valve is provided between the air inlet pipe 24 and the fixed column 21, and a switch 215 is provided in the fixed column 21 to resist the guide column 2131. When the guide column 2131 moves partially and moves away from the switch 215, the switch 215 opens the valve between the air inlet pipe 24 and the fixed column 21. That is, when the glass is placed on the multiple groups of fixed columns 21, the push table 212 will be squeezed by gravity. At this time, the guide column 2131 on the movable column 213 will move to a certain position along the spiral groove 2103, thereby canceling the friction with the guide column 2131. The switch 215 is contacted to open the valve on the air inlet pipe 24. At this time, when the air supply part 121 is evacuated, it will cooperate with the air inlet pipe 24 to extract the gas in the fixed column 21, pulling the push platform 212 down. When the glass is attached to the top of the fixed column 21, as the air inlet pipe 24 continues to extract, the glass is adsorbed and fixed on the fixed column 21. Before the glass is adsorbed, the density of the fixed column 21 is adjusted by adjusting the height of the driving bar 25 and the driving bar 25 to ensure that there are at least four groups of fixed columns 21. 1 Supporting the finished glass, that is, the finished glass product is supported by at least four groups of fixed columns 21 after processing. At this time, even if the adsorption of the glass is cancelled, the glass product can still remain stable. In order to ensure the utilization efficiency of the glass, the area of ​​the glass scraps after cutting is smaller than the area of ​​the finished glass. When the adsorption of the glass by the fixed columns 21 is cancelled after cutting, since the area of ​​the scraps is smaller than the area of ​​the finished glass, a single fixed column 21 and two fixed columns 21 cannot support the glass fragments well. In order to better separate the glass fragments from the finished glass, a ball 2121 is arranged on the push table 212. When the adsorption of the glass is cancelled, the ball 2121 extends out. Since the ball 2121 is spherical, the contact area with the glass is reduced. For the finished glass supported by multiple groups of fixed columns 21, the stability will not be affected. However, for the single glass fragments supported by multiple or more than two, the instability is increased due to the reduction of the support point area, which further assists the automatic falling of the glass fragments.

[0043] A rotating rod 23 is rotatably mounted on the mounting sleeve 22, and adjacent fixed columns 21 are rotatably connected via the rotating rod 23. Four groups of rotating rods 23 are provided on the mounting sleeve 22 and are distributed in a circular array, and one end of the rotating rod 23 away from the mounting sleeve 22 is rotatably connected to the rotating rod 23 on the adjacent suction member 2 via a rotating shaft, and the adjacent fixed columns 21 are pulled closer and farther away by lifting and pulling down the rotating shaft between the rotating rods 23; a driving bar 1 25 and a driving bar 2 26 are used to drive the rotating rod 23, and the driving bar 1 25 and the driving bar 2 26 are perpendicular to each other in the same horizontal plane, and the driving bar 1 25 and the driving bar 2 26 are connected to the rotating shaft via a bracket, and the height of the bracket on the driving bar 26 is greater than the height of the bracket on the driving bar 1 25, so as to prevent The driving bar 1 25 and the driving bar 2 26 interfere with each other when they respectively drive the rotating rod 23. Two groups of driving cylinders are provided on the workbench 1, and the driving ends of the two groups of driving cylinders are respectively connected to the driving bar 1 25 and the driving bar 2 26. When the driving bar 1 25 rises, the angle between the two adjacent groups of rotating rods 23 in the transverse direction gradually increases, thereby pushing the suction members 2 and the movable platform 133 away from each other, and increasing the lateral distance between the adjacent suction members 2. When the driving bar 2 26 rises, the angle between the two adjacent groups of rotating rods 23 in the longitudinal direction increases, thereby pushing the suction members 2 and the movable platform 133 away from each other, and increasing the longitudinal distance between the adjacent suction members 2. Conversely, the lateral distance and the longitudinal distance between the suction members 2 are reduced.

[0044] Working principle: the glass to be cut is placed on multiple groups of fixed columns 21, at which time the push platform 212 partially descends to open the valve on the air inlet pipe 24, and then the drive bar 1 25 and the drive bar 2 26 are driven to rise and fall according to the area of ​​the finished glass product to be cut, so as to change the density of the fixed columns 21, and keep at least four groups of fixed columns 21 supporting the finished glass product. Then, the gas in the fixed columns 21 is extracted in cooperation with the gas supply part 121 and the air inlet pipe 24, and the push platform 212 descends until the glass contacts the top of the fixed columns 21. As the air inlet pipe 24 continues to extract, the glass is adsorbed and fixed on the fixed columns 21. After the laser module 14 cuts the entire piece of glass, the air inlet pipe 24 releases the gas extraction from the fixed columns 21. At this time, the push platform 212 rises under the action of the resetting of the elastic member 214, and the movable column 213 cooperates with the spiral groove 2103 to lower the The rising speed of the push platform 212 prevents damage to the glass, protects the glass, and prevents the finished glass from being ejected. Later, the glass fragments cannot be supported by multiple groups of fixed columns 21 and fall into the guide hopper 111 for centralized collection. At the same time, the fixed columns 21 that are not in contact with the glass are not squeezed, and the guide columns 2131 on the movable columns 213 are in the upper limit position under the action of the elastic member 214, thereby squeezing the switch 215 to close the valve on the air inlet pipe 24, and the fixed column 21 supporting the finished glass opens the corresponding valve on the air inlet pipe 24, and finally the air supply member 121 is opened again to cooperate with the air inlet pipe 24 to extract the gas in the fixed column 21 supporting the finished glass, fix the finished glass, and finally cooperate with the suction cup to adsorb the finished glass. When the external suction cup adsorbs, the air inlet pipe 24 is cancelled to extract the gas in the fixed column 21 to take out the finished glass.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
