Description

Technical Field

[0001] The present invention belongs to the technical field of floor-to-ceiling window welding processing, and specifically relates to a multi-station synchronous welding device for floor-to-ceiling windows. Background Technique

[0002] Floor-to-ceiling windows are windows that maximize window height by fixing them directly to the floor surface. Most floor-to-ceiling windows are used in office buildings or rooms with poor lighting. They can increase the lighting in the room and offer an outside view, helping to relieve the mental burden of viewers and making people feel physically and mentally comfortable. The manufacturing of floor-to-ceiling windows typically involves splicing four square pipe fittings together, then welding and fixing the splicing joints using welding equipment, followed by grinding and polishing, and finally painting the surface to complete the manufacturing process.

[0003] A patent with publication number CN118682400B discloses a welding assistance device for door and window aluminum frames. This device enables convenient adjustment of the working positions of the welding device and the electromagnet, automatically retrieves gaskets from the gasket storage device using the electromagnet, and, in combination with multi-angle and multi-size welding of the welding device, can stably weld the gaskets to the connection ends of door and window aluminum materials. It has a high degree of automation, a wide range of applications, and reduces the labor intensity of workers. By internally supporting thin-walled aluminum square pipes (e.g., square pipe wall thicknesses of 0.6 cm, 0.8 cm, etc.) with gaskets, the deformation and collapse rate during welding can be effectively reduced, improving welding quality and efficiency. The drive assembly can adjust the working positions of multiple aluminum frame clamping components to adapt to various sizes and specifications of door and window aluminum materials (square pipes), with a wide range of applications and high working efficiency.

[0004] The above solution still has some problems in practical applications. Usually, four cut metal pipes are placed on the base, and the four cut metal pipes are butt-jointed and assembled into a floor-to-ceiling window frame. Then, a laser welder is used to weld the butt joints of the assembled floor-to-ceiling window frame. Since there are four butt joints, the laser welder needs to be used to weld each of the four butt joints one by one. However, the existing welding device not only has low welding efficiency but also does not filter the toxic gases generated during welding. Operators are prone to safety hazards such as lung diseases after long-term inhalation. Moreover, after welding, the welded joints need to be ground and polished, which affects the processing efficiency of the entire floor-to-ceiling window frame.

[0005] Therefore, the present invention provides a multi-station synchronous welding device for floor-to-ceiling windows. Summary of the Invention

[0017] 2. A multi-station synchronous welding device for floor-to-ceiling windows according to the present invention drives the rotating block to drive the telescopic cover to move downward, thereby driving the grinding sheet to press and fix the floor-to-ceiling window frame. Then, when the rotating block continues to move downward to adjust the focal length of the laser welding head, the telescopic cover slides inside the rotating block, thereby pulling the tension spring upward. Then, using the reset tension of the tension spring, the grinding sheet can be more closely attached to the floor-to-ceiling window frame. At the same time, the laser welding head is started to operate. Thus, when the rotating block drives the laser welding head to weld the butt joint of the floor-to-ceiling window frame, the rotating block can drive the telescopic cover and the grinding sheet to polish the welding part of the floor-to-ceiling window frame. Moreover, the toxic gas generated by the welding of the laser welding head can also be filtered by the rotating block. Since the rotating block is provided with a combined filtering material in the inner cavity of the telescopic cover, harmful gases and odors can be removed, improving the safety of floor-to-ceiling window welding processing, improving the working environment of the factory, and making the whole welding device more environmentally friendly.

Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0021] Embodiment 1: As Figures 1 to 9 shown, a multi-station synchronous welding device for floor-to-ceiling windows according to an embodiment of the present invention includes a base 1 and a floor-to-ceiling window frame 3 installed above the base 1, and is characterized in that: a support plate 14 is installed on one side of the lower end surface of the base 1, a servo push rod 4 is installed on the upper end of the support plate 14, and the piston rod end of the servo push rod 4 is installed with a welding adjustment component 5; And the welding adjustment component 5 includes a mounting frame 51 installed at the piston rod end of the servo push rod 4, an L-shaped sliding frame 53 is slidably connected to the inner cavity of the mounting frame 51, and a fixed rod 6 is installed at the upper end of the L-shaped sliding frame 53; Receiving grooves 18 are opened at both ends of the fixed rod 6, a telescopic rod 8 is slidably connected to the inner cavity of the receiving groove 18, a U-shaped fixing block 9 is installed at one end of the telescopic rod 8, a rotating block 12 is rotatably connected to the inner cavity of the U-shaped fixing block 9, and a laser welding head 11 is installed at one end of the rotating block 12; A telescopic cover 10 is slidably connected inside the rotating block 12. Multiple exhaust holes are provided at the upper end of the telescopic cover 10 for filtering and discharging the toxic gases generated during the welding of the floor-to-ceiling window frame 3. A grinding sheet 15 is adhered to the lower end of the telescopic cover 10, and the grinding sheet 15 is used for grinding and polishing the welding part of the floor-to-ceiling window frame 3.

[0022] Specifically, in the prior art, usually four cut metal pipes are placed on the base, and the four cut metal pipes are mutually butted and assembled into a floor-to-ceiling window frame. Then, a laser welder is used to weld the butted parts of the assembled floor-to-ceiling window frame. Since there are four butted parts, the laser welder needs to be used to weld and process the four butted parts one by one. However, the existing welding device not only has low welding efficiency but also does not have the function of filtering the toxic gases generated during welding. It is easy for operators to have safety hazards such as lung diseases after inhaling for a long time. And after welding, the welding parts also need to be ground and polished, which affects the processing efficiency of the entire floor-to-ceiling window frame. When the floor-to-ceiling window frame 3 is welded and processed in the present invention, four metal pipes are butted and installed on the base 1, and then the servo push rod 4 is started to drive the mounting frame 51 to move downward, and the mounting frame 51 drives the L-shaped sliding frame 53 to move downward, and further the L-shaped sliding frame 53 drives the fixing rod 6 to move downward, so as to adjust and calibrate the welding part of the laser welding head 11 and the floor-to-ceiling window frame 3, which can ensure that the laser beam is accurately irradiated to the part to be welded, avoid the reduction of the weld quality of the welding part of the floor-to-ceiling window frame 3 caused by tiny position deviations, and even affect the structural strength and stability of the entire frame, resulting in potential safety hazards in subsequent use. At the same time, by driving the telescopic rod 8 to slide in the inner cavity of the receiving groove 18, the telescopic rod 8 drives the U-shaped fixing block 9 to move synchronously, and the U-shaped fixing block 9 drives the rotating block 12 to move, and then drives the laser welding head 11 to move and adjust the welding position. Then, by driving the L-shaped sliding frame 53 to slide in the inner cavity of the mounting frame 51, the L-shaped sliding frame 53 drives the fixing rod 6 to move, so as to adjust the position of the laser welding head 11 according to the welding position of the floor-to-ceiling window frame 3, so that the laser welding head 11 can accurately weld the welding part of the floor-to-ceiling window frame 3. Moreover, during the process of the servo push rod 4 driving the rotating block 12 to move downward, the rotating block 12 drives the telescopic cover 10 to move downward synchronously, and the telescopic cover 10 drives the grinding sheet 15 to move downward, so that the grinding sheet 15 is pressed against the upper surface of the floor-to-ceiling window frame 3. As the rotating block 12 continues to move downward, the telescopic cover 10 slides inside the rotating block 12, and at the same time calibrates the laser welding head 11. Then, the laser welding head 11 is started to weld the welding part of the floor-to-ceiling window frame 3. The toxic gas generated by the welding of the floor-to-ceiling window frame 3 by the laser welding head 11 will remain in the inner cavity of the telescopic cover 10, and the toxic gas is filtered and discharged through the discharge holes at the upper end of the telescopic cover 10, thereby reducing the harm to the body of the operator inhaling the toxic gas generated by laser welding for a long time. During the operation of the laser welding head 11, by driving the rotating block 12 to rotate, the rotating block 12 drives the laser welding head 11 to move and weld along the welding part of the floor-to-ceiling window frame 3. At the same time, the rotating block 12 also drives the telescopic cover 10 to move, and the telescopic cover 10 drives the grinding sheet 15 to polish the welding part of the floor-to-ceiling window frame 3, thereby realizing the automatic welding processing of the floor-to-ceiling window and solving the above problems.

[0023] As Figure 2 , Figure 5 and Figure 6 shown, a tension spring 21 is installed on the upper end surface of the rotating block 12, and one end of the tension spring 21 is fixedly connected to the telescopic cover 10. A combined filter material is arranged at the position of the rotating block 12 in the inner cavity of the telescopic cover 10, and the combined filter material is composed of a HEPA high-efficiency filter, an activated carbon filter layer and a sponge filter layer, which is used to filter the toxic gas generated by the welding of the floor-to-ceiling window frame 3.

[0024] Specifically, during the process of driving the rotating block 12 to move downward, the rotating block 12 will drive the telescopic cover 10 to move downward, and then the telescopic cover 10 will drive the grinding disc 15 to press and fix the French window frame 3. Then, when the rotating block 12 continues to move downward to adjust the laser welding head 11 to calibrate the focal length, the telescopic cover 10 will slide inside the rotating block 12, and then the telescopic cover 10 will pull the tension spring 21 to move upward. Then, by using the reset tension of the tension spring 21, the grinding disc 15 can be more closely attached to the French window frame 3. At the same time, the laser welding head 11 is started to operate. Then, when the driving rotating block 12 drives the laser welding head 11 to weld the butt joint of the French window frame 3, the rotating block 12 can drive the telescopic cover 10 and the grinding disc 15 to polish the welding part of the French window frame 3. Moreover, the toxic gas generated by the welding of the laser welding head 11 can also be filtered by the rotating block 12. Since the rotating block 12 is provided with a combined filter material in the inner cavity of the telescopic cover 10, and the combined filter material is composed of a HEPA high-efficiency filter, an activated carbon filter layer, and a sponge filter layer, the HEPA high-efficiency filter can be used to capture fine dust particles and smoke, and then the activated carbon filter layer and the sponge filter layer are used to remove harmful gases and odors, thereby improving the safety of the French window welding process, improving the working environment of the factory, making the entire welding device more environmentally friendly, and thus solving the problem that in the existing multi-station synchronous welding device for French windows, after the butt joint of the French window frame is welded, usually the operator uses a polishing machine to polish the welding part, resulting in cumbersome operation and low efficiency. Moreover, when using a laser welder to weld the butt joint of the French window frame, a large amount of toxic gas will be generated by the French window frame. If it is not filtered and purified, the operator will be at risk of physical harm if inhaling it for a long time.

[0025] As Figure 3 、 Figure 4 and Figure 5 shown, one end of the mounting frame 51 is installed with a first motor 13. The inner cavity of the mounting frame 51 is rotatably connected with a threaded rod 52. The output shaft end of the first motor 13 is fixedly connected to one end of the threaded rod 52. The L-shaped sliding frame 53 is threadedly connected to the threaded rod 52 and is used to drive the L-shaped sliding frame 53 to slide in the inner cavity of the mounting frame 51, so that the L-shaped sliding frame 53 can drive the fixed rod 6 and the laser welding head 11 to move and adjust the position.

[0026] Specifically, after the floor-to-ceiling window frame 3 is spliced and installed, the first motor 13 is started to drive the threaded rod 52 to rotate, and the threaded rod 52 is threadedly driven to make the L-shaped sliding frame 53 slide and move in the inner cavity of the mounting frame 51. Furthermore, the L-shaped sliding frame 53 drives the fixed rod 6 to move synchronously, and at the same time, the fixed rod 6 drives the rotating block 12 to move, and then drives the laser welding head 11 to move synchronously to adjust the position, so as to facilitate the laser welding head 11 to align with the butt joint of the floor-to-ceiling window frame 3 and improve the welding accuracy.

[0027] As Figure 2 , Figure 4 and Figure 5 shown, a second motor 16 is installed at one end of the fixed rod 6. A transmission bevel gear 20 is fixedly connected to the output shaft end of the second motor 16 in the inner cavity of the fixed rod 6. The transmission bevel gear 20 is meshed with a driven bevel gear 19. A bidirectional threaded rod 17 is fixedly connected inside the driven bevel gear 19. The bidirectional threaded rod 17 is rotatably connected in the inner cavity of the storage groove 18, and both ends of the bidirectional threaded rod 17 are threadedly connected to the telescopic rod 8 respectively.

[0028] Specifically, when welding and processing floor-to-ceiling window frames 3 of different sizes, the second motor 16 is started to drive the transmission bevel gear 20 to rotate, and the transmission bevel gear 20 is meshed to drive the driven bevel gear 19 to rotate. Then, the driven bevel gear 19 drives the bidirectional threaded rod 17 to rotate. During the rotation of the bidirectional threaded rod 17, the telescopic rod 8 will be threadedly driven to slide in the inner cavity of the storage groove 18, and then drive the U-shaped fixing block 9 to move synchronously. At the same time, the U-shaped fixing block 9 drives the rotating block 12 to move, and then drives the laser welding head 11 to move synchronously to adjust the position, so as to realize the adjustment of the welding position for floor-to-ceiling window frames 3 of different sizes and improve the practicability of the welding device.

[0029] As Figure 2 , Figure 3 and Figure 5 shown, an angle adjustment assembly 7 is arranged at the upper end of the fixed rod 6. The angle adjustment assembly 7 includes a U-shaped bracket 75 installed on the upper end surface of the fixed rod 6. A first rack 72 and a second rack 73 are respectively slidably connected in the inner cavity of the U-shaped bracket 75, and the first rack 72 and the second rack 73 are symmetrically arranged. A servo motor is installed at the bottom of the inner cavity of the U-shaped bracket 75, and a transmission gear 71 is fixedly connected to the output shaft end of the servo motor. The transmission gear 71 is meshed with the first rack 72 and the second rack 73, and is used to drive the first rack 72 and the second rack 73 to move away from or close to each other, and can drive the rotating block 12 to drive the laser welding head 11 to adjust the welding angle.

[0030] As Figure 2 , Figure 3 and Figure 5As shown in the figure, a driven gear 74 is fixedly connected to the upper end of the rotating block 12 through the U-shaped fixing block 9. The driven gear 74 is respectively meshed and connected with a first rack 72 and a second rack 73, and the first rack 72 and the second rack 73 are used to drive the driven gear 74 to rotate, which can drive the rotating block 12 to rotate, and then drive the laser welding head 11 to adjust the welding angle.

[0031] Specifically, when welding the butt joint of the floor-to-ceiling window frame 3, by driving the transmission gear 71 to rotate and making the transmission gear 71 meshingly drive the first rack 72 and the second rack 73 to move, and further making the first rack 72 and the second rack 73 slide away from each other in the inner cavity of the U-shaped bracket 75. When the first rack 72 and the second rack 73 move away from each other, the first rack 72 and the second rack 73 will meshingly drive the driven gear 74 to rotate, and then drive the rotating block 12 to rotate. At the same time, the rotating block 12 drives the laser welding head 11 to rotate and adjust the angle, so as to be able to adjust the welding angle according to different models of the floor-to-ceiling window frame 3, so as to facilitate the laser welding head 11 to weld the butt joint of the floor-to-ceiling window frame 3. Moreover, during the welding process of the butt joint of the floor-to-ceiling window frame 3 (it can be programmed by the controller in advance according to the floor-to-ceiling window frames of the same batch of models to achieve automatic adjustment welding), at the same time, driving the telescopic rod 8 can drive the U-shaped fixing block 9 to move and adjust the position, so as to realize the welding work of the butt joint of the floor-to-ceiling window frame 3, thus solving the problem that when the existing multi-station synchronous welding device for floor-to-ceiling windows welds floor-to-ceiling window frames of different models, due to the inconvenience of adjusting the position and angle of the laser welding device in the existing welding device, the welding device can only weld and process floor-to-ceiling window frames of the same batch of models.

[0032] Embodiment 2: As Figure 1 、 Figure 7 and Figure 8 shown, a floor-to-ceiling window positioning component 2 is arranged on the upper end surface of the base 1, and the floor-to-ceiling window positioning component 2 includes a first rotating frame 201 rotatably connected inside the upper end surface of the base 1, and a second rotating frame 202 is rotatably connected inside the upper end of the first rotating frame 201 for supporting the floor-to-ceiling window frame 3 to wait for welding.

[0033] As Figure 1 、 Figures 7 to 9 shown, T-shaped chutes 203 are opened at both ends inside the first rotating frame 201 and the second rotating frame 202, and a T-shaped sliding rod 204 is slidably connected to the inner cavity of each T-shaped chute 203. One end of the T-shaped sliding rod 204 is fixedly connected with a T-shaped supporting block 205, and a first spring 206 is fixedly connected to one side of the T-shaped sliding rod 204. One end of the first spring 206 is fixedly connected to the inner wall of the T-shaped chute 203.

[0034] As Figure 1 、 Figures 7 to 9As shown, second springs 207 are fixedly connected to the inner cavities at both ends of the T-shaped supporting block 205. One end of each second spring 207 is fixedly connected to a sliding column 208, and the sliding column 208 is slidably connected in the inner cavity of the T-shaped supporting block 205. One end of the sliding column 208 is fixedly connected to a clamping block 209, which is used for clamping and positioning the four right angles of the floor-to-ceiling window frame 3.

[0035] Specifically, when splicing and installing the floor-to-ceiling window frame 3, by placing four metal pipe fittings on the upper ends of the first rotating frame 201 and the second rotating frame 202, and simultaneously rotating the first rotating frame 201 and the second rotating frame 202 to drive the four metal pipe fittings to move synchronously, the cut ends of the four metal pipe fittings are spliced together. Moreover, the butt joint of the floor-to-ceiling window frame 3 is installed on the upper end of the T-shaped supporting block 205. At the same time, the second spring 207 bounces the sliding column 208 into the inner cavity of the T-shaped supporting block 205, so that the sliding column 208 drives the clamping blocks 209 to move closer to each other, thereby enabling the clamping blocks 209 to abut and clamp the ninety-degree right angle of the floor-to-ceiling window frame 3. At the same time, the first spring 206 bounces the T-shaped sliding rod 204 into the inner cavity of the T-shaped sliding groove 203, so that the T-shaped sliding rod 204 pulls the T-shaped supporting block 205 to move synchronously, and the T-shaped supporting block 205 drives the clamping blocks 209 to move synchronously, thereby being able to further clamp and position the floor-to-ceiling window frame 3, ensuring the stability of the splicing of the floor-to-ceiling window frame 3, the tightness of the splicing joint of the floor-to-ceiling window frame 3, improving the quality and strength of the welding process of the floor-to-ceiling window frame 3. Moreover, by driving the first rotating frame 201 to rotate, the first rotating frame 201 can also drive the floor-to-ceiling window frame 3 and the second rotating frame 202 to rotate synchronously, thereby being able to adjust the welding position of the floor-to-ceiling window frame 3 according to the welding requirements. When directly moving the floor-to-ceiling window frame 3 to adjust the welding position, it is easy to cause the welding position of the floor-to-ceiling window frame 3 to shift, resulting in the trouble of wasting time to re-splice the floor-to-ceiling window frame 3. Thus, it solves the problem that in the existing multi-station welding device for floor-to-ceiling windows, when welding the floor-to-ceiling window frame, due to the inconvenience of clamping and positioning the spliced floor-to-ceiling window frame and ensuring the tightness of the splicing joint of the floor-to-ceiling window frame, the weld at the butt joint of the floor-to-ceiling window frame is shifted, thereby affecting the overall strength and stability of the floor-to-ceiling window in the later stage.

[0036] As Figure 1 、 Figure 2 and Figure 7 shown, a limiting block 22 is installed on the upper end surface of the T-shaped supporting block 205, and the limiting block 22 is used to abut against the ninety-degree right angle at the inner cavity of the floor-to-ceiling window frame 3 during operation.

[0037] Working principle: When splicing and installing the floor-to-ceiling window frame 3, place four metal pipe fittings on the upper ends of the first rotating frame 201 and the second rotating frame 202. At the same time, rotate the first rotating frame 201 and the second rotating frame 202 to drive the four metal pipe fittings to move synchronously, so as to splice the cut ends of the four metal pipe fittings together. Moreover, the butt joint of the floor-to-ceiling window frame 3 is installed on the upper end of the T-shaped support block 205. At the same time, use the second spring 207 to push up the sliding column 208 and slide it into the inner cavity of the T-shaped support block 205, so that the sliding column 208 drives the clamping blocks 209 to move closer to each other, thereby enabling the clamping blocks 209 to abut and clamp the 90-degree right angle of the floor-to-ceiling window frame 3. At the same time, the first spring 206 pushes up the T-shaped slide bar 204 and slides it into the inner cavity of the T-shaped slide groove 203, so that the T-shaped slide bar 204 pulls the T-shaped support block 205 to move synchronously, and the T-shaped support block 205 drives the clamping blocks 209 to move synchronously, thereby being able to further clamp and position the floor-to-ceiling window frame 3, and further ensuring the splicing stability of the floor-to-ceiling window frame 3, the tightness of the splicing part of the floor-to-ceiling window frame 3, improving the welding quality and strength of the floor-to-ceiling window frame 3. Moreover, by driving the first rotating frame 201 to rotate, the first rotating frame 201 can also drive the floor-to-ceiling window frame 3 and the second rotating frame 202 to rotate synchronously, so as to be able to adjust the welding position of the floor-to-ceiling window frame 3 according to the welding needs. When directly moving the floor-to-ceiling window frame 3 to adjust the welding position, it is easy to cause the welding position of the floor-to-ceiling window frame 3 to shift, resulting in the trouble of wasting time to re-splice the floor-to-ceiling window frame 3; When welding the butt joint of the floor-to-ceiling window frame 3, drive the transmission gear 71 to rotate, and make the transmission gear 71 mesh and drive the first rack 72 and the second rack 73 to move. Then, the first rack 72 and the second rack 73 slide and move away from each other in the inner cavity of the U-shaped bracket 75. When the first rack 72 and the second rack 73 move away from each other, the first rack 72 and the second rack 73 will mesh and drive the driven gear 74 to rotate, and then drive the rotating block 12 to rotate. At the same time, the rotating block 12 drives the laser welding head 11 to rotate and adjust the angle, so as to be able to adjust the welding angle according to different models of the floor-to-ceiling window frame 3, so as to facilitate the laser welding head 11 to weld the butt joint of the floor-to-ceiling window frame 3. Moreover, during the welding process of the butt joint of the floor-to-ceiling window frame 3 (it can be programmed by the controller in advance according to the same batch of models of the floor-to-ceiling window frames to achieve automatic welding adjustment), at the same time, drive the telescopic rod 8 to be able to drive the U-shaped fixing block 9 to move and adjust the position, so as to realize the welding work of the butt joint of the floor-to-ceiling window frame 3; During the process of driving the rotating block 12 to move downward, the rotating block 12 will drive the telescopic cover 10 to move downward. As a result, the telescopic cover 10 will drive the grinding disc 15 to press and fix the floor-to-ceiling window frame 3. Then, when the rotating block 12 continues to move downward to adjust the laser welding head 11 for focal length calibration, the telescopic cover 10 will slide inside the rotating block 12, causing the telescopic cover 10 to pull the tension spring 21 upward. Then, by using the restoring force of the tension spring 21, the grinding disc 15 can be made to fit more closely with the floor-to-ceiling window frame 3. At the same time, the laser welding head 11 is started to operate. When the rotating block 12 drives the laser welding head 11 to weld the butt joint of the floor-to-ceiling window frame 3, the rotating block 12 can drive the telescopic cover 10 and the grinding disc 15 to polish the welding area of the floor-to-ceiling window frame 3. Moreover, the toxic gas generated by the welding of the laser welding head 11 can be filtered by the rotating block 12. Since a combined filter material is provided at the inner cavity of the telescopic cover 10 in the rotating block 12, and the combined filter material is composed of a HEPA high-efficiency filter, an activated carbon filter layer, and a sponge filter layer, the HEPA high-efficiency filter can be used to capture fine dust particles and smoke, and then the activated carbon filter layer and the sponge filter layer can be used to remove harmful gases and odors, thereby improving the safety of the floor-to-ceiling window welding process, enhancing the working environment of the factory, and making the entire welding device more environmentally friendly.
