Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, and in particular to an angle positioning device for laser welding of glass aluminum frames. Background Technology

[0002] Laser welding utilizes high-energy laser pulses to locally heat a small area of ​​material. The energy of the laser radiation diffuses into the material through heat conduction, melting the material and forming a specific molten pool to achieve the welding purpose. Publication No. CN209919100U discloses a laser welding device, including a control cabinet, a platform assembly, and a welding assembly. The platform assembly is used for welding workpieces and is mounted on the platform assembly. The welding assembly includes a welding motion mechanism and a welding collimation assembly mounted on the output end of the welding motion mechanism. The welding collimation assembly emits laser light, and the welding motion mechanism drives the welding collimation assembly to move. The welding collimation assembly includes a mounting base and a collimation head rotatably connected to the mounting base. The mounting base is located at the output end of the welding motion mechanism. The angle between the collimation head and the output end of the welding assembly is adjusted by adjusting the angle between the collimation head and the mounting base. This method has the advantages of miniaturization and high welding precision. However, when the above technology is used, the workpiece may shift when placed on a flat steel plate, requiring the operator to correct and position the workpiece. In addition, the workpiece may also shift due to unexpected reasons during the welding process, resulting in poor welding quality. Therefore, it is necessary to change the technology. Utility Model Content

[0003] The purpose of this invention is to provide an angle positioning device for laser welding of glass aluminum frames, so as to at least solve the problems of the prior art mentioned above.

[0004] To achieve the above objectives, the present invention provides an angle positioning device for laser welding of glass aluminum frames, comprising a worktable. A first fixing block and a second fixing block are fixedly connected to the surface of the worktable. A bidirectional lead screw is rotatably connected between the first and second fixing blocks. A driving block is threadedly connected to the surface of the bidirectional lead screw. A clamping plate is fixedly connected to the top of the driving block. A sliding groove is formed on the surface of the clamping plate. A slider is slidably connected inside the sliding groove. A clamping block is fixedly connected to the surface of the slider. A threaded hole is formed on the surface of the clamping block. A screw is threadedly connected to the inside of the threaded hole. An adjusting knob is fixedly connected to the top of the screw. The bottom end of the screw abuts against the sliding groove. A glass plate is provided on the surface of the worktable. An aluminum frame strip is fitted around the edge of the glass plate. A handle is fixedly connected to one end of the bidirectional lead screw.

[0005] Optionally, there are four sets of clamping blocks, and the four sets of clamping blocks are symmetrically distributed in the middle two layers of the worktable.

[0006] Optionally, a protective pad, made of rubber, is fixedly connected to the surface of the clamping plate.

[0007] Optionally, the surface of the handle is fitted with a handle sleeve.

[0008] Optionally, the surface of the adjustment knob is fixedly connected with anti-slip ribs, which are evenly distributed on the surface of the adjustment knob.

[0009] Optionally, the surface of the clamp is provided with a T-slot and a socket, and the surface of the protective pad is fixedly connected with a T-shaped rod and a cylindrical rod. The T-shaped rod is slidably connected to the temporal part of the T-slot, and the cylindrical rod is inserted into the socket.

[0010] Optionally, an electric telescopic rod is fixedly connected to the bottom of the workbench, and a top plate is fixedly connected to the output end of the electric telescopic rod.

[0011] The corner positioning device for laser welding of glass aluminum frames provided in this embodiment of the utility model has at least one of the following technical effects:

[0012] 1. In this utility model, by setting up a bidirectional lead screw, handle, drive block, clamping plate and clamping block structure, when the glass to be welded is placed on the worktable, the handle is then turned, which drives the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw drives the drive block and clamping plate to clamp the edge of the glass plate, making the aluminum frame strip on the edge of the glass plate tightly attached to the edge of the glass plate. Then, the clamping block is adjusted so that it is also tightly attached to the aluminum frame strip, thereby positioning and fixing the joint of the aluminum frame strip at the corner of the glass plate. Then, the laser welding gun can be used for welding. This realizes the clamping, positioning and fixing of the glass plate and the aluminum frame fitted on the edge of the glass plate, so that the joint of the aluminum frame strip at the corner of the glass plate can be aligned, avoiding the glass plate shaking and shifting during the welding operation, causing the corner aluminum frame strip joint to be misaligned and affecting the welding accuracy. At the same time, it can also perform welding operations on the aluminum frame strip of glass plates of different sizes.

[0013] 2. In this utility model, by setting up an electric telescopic rod and a top plate structure, after the welding work is completed, the clamping plate and the clamping plate fixing the glass plate are released. Then, the electric telescopic rod is started, and the output end of the electric telescopic rod pushes the top plate to lift the glass plate. The worker can then remove the glass plate and put in the next set of glass plates to be welded. This realizes that the glass plate welded at the joint of the aluminum frame strip can be lifted up, making it convenient for the worker to quickly remove the glass plate from the workbench and replace the next set of aluminum frame strips to be welded, which helps to improve the welding work efficiency.

[0033] Example 1

[0034] Please see Figure 1-5This utility model provides a technical solution: an angle positioning device for laser welding of glass aluminum frames, including a worktable 1. A first fixing block 2 and a second fixing block 3 are fixedly connected to the surface of the worktable 1. A bidirectional lead screw 4 is rotatably connected between the first fixing block 2 and the second fixing block 3. A drive block 5 is threadedly connected to the surface of the bidirectional lead screw 4. A clamping plate 6 is fixedly connected to the top of the drive block 5. A groove 7 is formed on the surface of the clamping plate 6. A slider 8 is slidably connected inside the groove 7. A clamping block 9 is fixedly connected to the surface of the slider 8. A threaded hole 10 is formed on the surface of the clamping block 9. A screw 11 is threadedly connected inside the threaded hole 10. An adjusting knob 12 is fixedly connected to the top of the screw 11. The bottom end of the screw 11 abuts against the groove 7. A glass plate 19 is provided on the surface of the worktable 1. An aluminum frame strip 20 is fitted around the edge of the glass plate 19. A handle 21 is fixedly connected to one end of the bidirectional lead screw 4. The number of clamping blocks 9 is four. Four sets of clamping blocks 9 are symmetrically distributed in two layers in the middle of the workbench 1. This facilitates the simultaneous fixing of the joints of the aluminum frame strips 20 at the corners of the glass plate 19, improving the stability of the positioning and fixing of the joints of the aluminum frame strips 20. A protective pad 14 made of rubber is fixedly connected to the surface of the clamping plate 6. This protects the aluminum frame strips 20 and prevents them from being pinched or scratched when the clamping blocks 9 work with the clamping plate 6 to position and fix the aluminum frame strips 20. A handle sleeve 22 is fitted on the surface of the handle 21. This improves the comfort of holding the handle 21 and prevents hand discomfort caused by friction when turning the handle 21. Anti-slip ribs 13 are fixedly connected to the surface of the adjusting knob 12. The anti-slip ribs 13 are evenly distributed on the surface of the adjusting knob 12. This increases the stability of the fingers when turning the adjusting knob 12 and prevents slippage.

[0035] Example 2

[0036] Please see Figure 3 The surface of the clamping plate 6 is provided with a T-slot 17 and an insertion hole 18. The surface of the protective pad 14 is fixedly connected with a T-shaped rod 15 and a cylindrical rod 16. The T-shaped rod 15 is slidably connected to the temporal part of the T-slot 17, and the cylindrical rod 16 is inserted into the insertion hole 18, which facilitates the disassembly and assembly of the protective pad 14. This facilitates the replacement of the protective pad 14 that has aged and been damaged after long-term use. The bottom of the workbench 1 is fixedly connected with an electric telescopic rod 24. The output end of the electric telescopic rod 24 is fixedly connected with a top plate 23. This can lift the glass plate 19 after welding at the joint of the aluminum frame strip 20. This makes it convenient for workers to quickly remove the glass plate 19 from the workbench 1 and replace the next set of aluminum frame strips 20 to be welded, which helps to improve the welding efficiency.

[0037] Working principle: During use, when the glass to be welded is placed on the workbench 1, and then the handle 21 is turned, the handle sleeve 22 on the handle 21 is released from the palm, and the handle 21 drives the bidirectional lead screw 4 between the first fixing block 2 and the second fixing block 3 to rotate. The rotation of the bidirectional lead screw 4 drives the drive block 5 and the clamping plate 6 to clamp the edge of the glass plate 19, so that the aluminum frame strip 20 on the edge of the glass plate 19 is in close contact with the edge of the glass plate 19, and the protective pad 14 on the clamping plate 6 abuts against the outer edge of the aluminum frame strip 20. Then, the adjustment... The clamping block 9 is aligned tightly against the aluminum frame strip 20. Then, the adjusting knob 12 is rotated, causing the screw 11 to rotate downwards inside the threaded hole 10 and pass through the slider 8 to abut against the ground of the slide groove 7. This positions and fixes the joint of the aluminum frame strip 20 at the corner of the glass plate 19. Afterwards, welding can be performed using a handheld laser welding gun. This achieves clamping, positioning, and fixing of the glass plate 19 and the aluminum frame fitted around its edge, ensuring alignment of the joint of the aluminum frame strip 20 at the corner of the glass plate 19 and preventing welding problems. The glass plate 19 wobbles and shifts, causing misalignment of the corner aluminum frame strip 20 joints and affecting welding accuracy. Simultaneously, welding operations can be performed on the aluminum frame strips 20 of glass plates 19 of different sizes. After welding is completed, the clamping plates 6 and their fixing to the glass plate 19 are released. Then, the electric telescopic rod 24 is activated. The output end of the electric telescopic rod 24 pushes the top plate 23 to lift the glass plate 19. The worker can then remove the glass plate 19 and place the next set of glass plates 19 to be welded. This allows for the welding of the joints of the aluminum frame strips 20 onto the glass plate 19. The glass plate 19 is lifted up, making it easy for workers to quickly remove the glass plate 19 from the workbench 1 and replace the next set of aluminum frame strips 20 to be welded, which helps to improve welding efficiency. When the protective pad 14 needs to be replaced, hold the edge of the anti-slip pad and pull it outward so that the cylindrical rod 16 on the protective pad 14 disengages from the insertion hole 18 on the clamping plate 6. Then, the protective pad 14 is removed from the clamping plate 6, and the T-shaped rod 15 on the protective pad 14 disengages from the T-shaped groove 17 on the clamping plate 6. Then, a new protective pad 14 can be replaced.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
