Description

Technical Field

[0001] This invention belongs to the field of photovoltaic power generation equipment manufacturing technology, specifically, it relates to a laser welding forming equipment and process for a photovoltaic motor saddle bracket. Background Technology

[0002] As the core driving component of a solar power generation system, the operational stability of the photovoltaic motor directly affects the efficiency of the entire system. The saddle bracket, as a key support structure for the motor, undertakes multiple tasks, including fixing the motor, absorbing vibration, and ensuring transmission accuracy. Therefore, extremely high requirements are placed on the welding quality of the bracket. Laser welding technology, due to its advantages of high energy density, small heat-affected zone, fast welding speed, and high degree of automation, is widely used in the precision welding process of saddle brackets, effectively meeting the connection strength requirements of complex curved surface structures.

[0003] However, in actual operation, existing laser welding forming equipment generates intense boiling and vaporization of the molten pool when the high-energy beam acts on the surface of the metal material. This inevitably leads to a large amount of high-temperature molten metal being spattered in the form of sparks. For workpieces with complex three-dimensional structures, such as saddle brackets, the welding path usually involves multi-angle and multi-directional movement trajectories, making it difficult to precisely control the range and direction of the spark spatter. Currently available laser welding equipment fails to effectively shield these high-temperature sparks, causing molten slag and sparks to easily land on the densely distributed precision pipes, control circuits, and sensor connectors inside the equipment. Once these high-temperature particles adhere, they can cause minor damage such as aging and breakage of the circuit insulation layer, leading to signal transmission failures. In severe cases, they may burn out the pipes or ignite surrounding combustibles, seriously affecting the continuous and stable operation of the equipment and increasing the frequency of equipment downtime for maintenance and maintenance costs. Therefore, we propose a laser welding forming equipment and process for photovoltaic motor saddle brackets. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: A laser welding forming device for a photovoltaic motor saddle bracket includes a welding table, a support leg installed at the bottom of the welding table, an electric slide rail one installed at the top of the welding table, a support slide plate slidably connected to the top of the electric slide rail one, a gantry frame installed at the top of the support slide plate, an electric slide rail two at the top of the inner wall of the gantry frame, a connecting slide plate slidably connected to the bottom of the electric slide rail two, an electric cylinder installed at the bottom of the connecting slide plate, a connecting plate installed at the output end of the electric cylinder, a motor installed at the top of the connecting plate, a fixing plate installed at the bottom of the output shaft of the motor, a laser welding head penetrating through the fixing plate, a baffle sleeve fitted near the bottom of the laser welding head, a heat utilization mechanism for slow cooling and preheating of the welding position provided on the baffle, and an anti-collision buffer mechanism provided between the baffle and the laser welding head.

[0005] In a preferred embodiment of the present invention, the heat utilization mechanism includes an outer spiral heat exchange tube, an inner spiral heat exchange tube, and a micro water pump. The outer spiral heat exchange tube and the inner spiral heat exchange tube are respectively surrounding the outer wall and inner wall of the baffle. An outer shell is provided outside the outer spiral heat exchange tube, and the outer shell is installed on the outer wall of the baffle. A mounting hole is provided on the baffle, and a micro water pump is disposed inside the mounting hole. A coupling is connected between the micro water pump and the inner wall of the mounting hole. A suction pipe is provided between the input end of the micro water pump and the inner spiral heat exchange tube, and a guide pipe is provided between the output end of the micro water pump and the outer spiral heat exchange tube. A hollow ring plate is installed at the bottom of the outer shell and is mounted on the outer wall of the baffle. Multiple miniature air pumps are installed between the hollow ring plate and the outer shell. An air intake pipe is connected to the outer shell at the input end of the miniature air pump, and an air outlet pipe is connected to the hollow ring plate at the output end of the miniature air pump. A V-shaped nozzle is connected to the bottom end of the hollow ring plate, and multiple air inlets are opened at the top of the outer shell. By setting the V-shaped nozzle, the air pressure of the air curtain sprayed by the nozzle can be increased. By setting the air inlets, normal air circulation inside the outer shell can be ensured. In addition, the inner wall of the outer shell is lined with fiberglass felt with aluminum foil, which improves the heat insulation effect of the outer shell.

[0006] In a preferred embodiment of the present invention, the baffle, the outer spiral heat exchange tube and the inner spiral heat exchange tube are all flared in shape, which is wider at the bottom and narrower at the top. By setting the baffle in a flared shape, the protection range of the baffle against sparks can be improved.

[0007] In a preferred embodiment of the present invention, the anti-collision buffer mechanism includes an elastic disc one, an elastic disc two, and a fixed sleeve. The elastic disc one and the elastic disc two are respectively disposed on the outer and inner sides of the top of the shield. Multiple positioning posts are installed at the top of the elastic disc two. Multiple positioning grooves are opened at the top of the inner wall of the shield, and the positioning posts are inserted into the positioning grooves. The fixed sleeve is fixedly sleeved on the outer wall of the laser welding head. Multiple hinge blocks one are installed at the bottom of the elastic disc two. Multiple buffer grooves are opened on the outer wall of the fixed sleeve. The inner wall of the buffer groove is slidably connected to the hinge block two. A stop rod is elastically hinged between the hinge block one and the hinge block two. A damping plate is installed on the inner wall of the buffer groove. The damping plate is in contact with the outer wall of the hinge block two. By setting the positioning posts, the positioning posts can be inserted into the positioning grooves, thereby limiting and stabilizing the shield. The elastic disc one and the elastic disc two are both made of silicone rubber.

[0008] In a preferred embodiment of the present invention, a connecting shaft is installed on the inner wall of the first hinge block and the second hinge block. A shaft hole is opened at both ends of the abutment rod. The connecting shaft moves through the shaft hole. A torsion spring is connected between the outer wall of the connecting shaft and the inner wall of the shaft hole. By setting the torsion spring, the abutment rod can rotate elastically.

[0009] In a preferred embodiment of the present invention, a limiting slide plate is installed on the outer wall of the second hinge block, and a limiting groove is formed on the inner wall of the buffer groove. The limiting slide plate is slidably connected to the limiting groove. By setting the limiting slide plate, the second hinge block can be limited, ensuring that the second hinge block can slide within the buffer groove.

[0010] In a preferred embodiment of the present invention, the positioning post is adapted to the positioning groove.

[0011] In a preferred embodiment of the present invention, both the outer spiral heat exchange tube and the inner spiral heat exchange tube are provided with heat transfer oil.

[0012] In a preferred embodiment of the present invention, the damping plate is made of asbestos fiber friction material.

[0013] This invention also provides a laser welding forming process for a photovoltaic motor saddle bracket, comprising the following steps: S1: First, place the bracket to be welded on the welding table, and then fix the bracket with external clamping equipment; S2: According to the preset welding process, the control system coordinates and schedules each actuator: electric slide rail one drives the support slide plate to realize the lateral movement of the welding head, electric slide rail two drives the connecting slide plate to complete the longitudinal feed, electric cylinder is responsible for adjusting the vertical height of the laser welding head, and motor adjusts the circumferential angle of the laser welding head by driving the fixed plate to rotate. Through the above multi-axis linkage, the laser welding head is precisely guided to the welding position of the bracket and performs welding operations along the predetermined trajectory. S3: During the welding process, the laser welding head first approaches the welding position. At this time, the laser welding head moves the baffle to block the welding position. The sparks generated by the laser welding head during the welding process are blocked by the baffle to prevent them from flying everywhere. S4: The spark blocked by the baffle will come into contact with the inner spiral heat exchange tube inside. The heat generated by the spark will be transferred to the inner spiral heat exchange tube to heat the heat transfer oil of the inner spiral heat exchange tube. At the same time, the micro water pump starts. S5: The micro water pump delivers the heated heat transfer oil in the inner spiral heat exchange tube to the liquid guide tube through the liquid suction tube, and then delivers it to the outer spiral heat exchange tube through the liquid guide tube, so that heat accumulates inside the shell. At the same time, multiple micro air pumps are started. S6: The miniature air pump delivers hot air from inside the shell to the outlet pipe through the intake pipe, and then to the hollow ring plate through the outlet pipe. Finally, it is ejected through the V-shaped nozzle. Because the V-shaped nozzle is annular, it can generate an annular high-temperature gas curtain. During the welding process, the laser welding head blows this high-temperature gas curtain toward the welded position, slowly cooling it, effectively reducing the cooling rate, preventing the formation of hardened structures, and thus releasing welding stress. At the same time, it also blows toward the position to be welded in advance, which plays a role in preheating and cleaning the position to be welded, reducing the temperature difference gradient during welding. In addition, the impact force of the airflow can also blow away the fine dust on the surface to be welded, improving the welding quality. S7: When the shield collides due to a human error in the programming, the shield will compress the elastic disc 2 and cause elastic deformation. At the same time, the elastic disc 2 will drive the hinge block 1 to move downward. The hinge block 1 will drive the abutment rod to rotate, causing the abutment rod to twist the torsion spring. The abutment rod will then drive the hinge block 2 to move downward, causing the hinge block 2 to slide against the damping plate. This will provide a good buffering effect for the shield and prevent the impact from being directly transmitted to the laser welding head through the shield, thus providing good protection for the laser welding head.

[0014] Compared with the prior art, the present invention has the following advantages: This invention, by setting up a heat utilization mechanism, can absorb the high-temperature heat from the splashing sparks during the welding process using the inner spiral heat exchange tube, and circulate the heated heat transfer oil to the outer spiral heat exchange tube through a micro water pump, so that heat energy is stored inside the shell. Then, the hot air is guided to the V-shaped nozzle by a micro air pump to form an annular high-temperature air curtain, realizing the slow cooling treatment of the area after welding and the preheating and cleaning of the area before welding, significantly reducing the residual stress in the weld area, thereby greatly improving the welding quality and structural strength of the bracket.

[0015] This invention, by setting up an anti-collision buffer mechanism, allows the elastic disk two to absorb part of the impact energy when the shield is accidentally collided due to program deviation or external interference. At the same time, through the linkage of hinge block one, the abutment rod and hinge block two, the hinge block two generates friction energy with the damping plate in the buffer groove. Since the mechanism adopts a ring-shaped multi-point symmetrical layout, it can effectively buffer impact forces from multiple directions such as horizontal, vertical and inclined, greatly improving the all-round protection effect of the laser welding head.

[0016] This invention achieves precise positioning and flexible steering of the laser welding head in space through multi-axis linkage control of electric slide rail one, electric slide rail two, electric cylinder and motor. It can adapt to the welding path requirements of the complex curved surface of the saddle support. At the same time, the baffle not only effectively prevents sparks from splashing, but also works in conjunction with the heat utilization mechanism to convert welding waste heat into process auxiliary energy, realizing energy recovery and utilization, and greatly improving the automation level, energy utilization efficiency and overall benefits of welding operations.

Multiple hinge blocks 30 are installed at the bottom of the elastic disc 27. Multiple buffer grooves 36 are opened on the outer wall of the fixed sleeve 39. The inner wall of the buffer groove 36 is slidably connected to the hinge block 35. A stop rod 34 is elastically hinged between the hinge block 30 and the hinge block 35.

[0025] Furthermore, a connecting shaft 31 is installed on the inner wall of hinge block 1 30 and hinge block 2 35, and shaft holes 32 are opened at both ends of the abutment rod 34.

Among them, by setting the limiting slide plate 37, the hinge block 35 can be limited, ensuring that the hinge block 35 can slide in the buffer slide groove 36.

[0027] Furthermore, the positioning post 28 is adapted to the positioning groove 29.

[0028] Furthermore, both the outer spiral heat exchange tube 14 and the inner spiral heat exchange tube 23 are filled with heat transfer oil.

[0029] Furthermore, the damping plate 40 is made of asbestos fiber friction material.

[0030] This invention also provides a laser welding forming process for a photovoltaic motor saddle bracket, comprising the following steps: S1: First, place the bracket to be welded on welding table 1, and then fix the bracket with external clamping equipment; S2: According to the preset welding process, the control system coordinates and schedules each actuator: the electric slide rail 1 3 drives the support slide plate 4 to realize the lateral movement of the welding head, the electric slide rail 2 5 drives the connecting slide plate 6 to complete the longitudinal feed, the electric cylinder 7 is responsible for adjusting the vertical height of the laser welding head 11, and the motor 10 adjusts the circumferential angle of the laser welding head 11 by driving the fixed plate 9 to rotate. Through the above multi-axis linkage, the laser welding head 11 is precisely guided to the welding position of the bracket and performs welding operations along the predetermined trajectory. S3: During the welding process, the laser welding head 11 first approaches the welding position. At this time, the laser welding head 11 drives the baffle 12 to block the welding position. The sparks generated by the laser welding head 11 during the welding process will be blocked by the baffle 12 to prevent them from splashing everywhere. S4: The spark blocked by the baffle 12 will come into contact with the inner spiral heat exchange tube 23 inside it. The heat generated by the spark will be transferred to the inner spiral heat exchange tube 23 to heat the heat transfer oil of the inner spiral heat exchange tube 23. At the same time, the micro water pump 20 starts. S5: The micro water pump 20 delivers the heated heat transfer oil in the inner spiral heat exchange tube 23 to the liquid guide tube 21 through the liquid suction pipe 22, and then delivers it to the outer spiral heat exchange tube 14 through the liquid guide tube 21, so that heat accumulates inside the outer shell 13. At the same time, multiple micro air pumps 16 are started. S6: The micro air pump 16 delivers hot air from inside the outer shell 13 to the outlet pipe 18 through the suction pipe 17, and then delivers it to the hollow ring plate 42 through the outlet pipe 18. Finally, it is ejected through the V-shaped nozzle 19. Since the V-shaped nozzle 19 is annular, it can generate an annular high-temperature gas curtain. During the welding process, the laser welding head 11 blows this high-temperature gas curtain toward the welding completed position to slowly cool it, effectively reducing the cooling rate and preventing the formation of hardened structures, thereby releasing welding stress. At the same time, it also blows it toward the position to be welded in advance, which plays a role in preheating and cleaning the position to be welded, reducing the temperature difference gradient during welding. Meanwhile, the impact force of the airflow can also blow away the fine dust on the surface to be welded, improving the welding quality. S7: When the shield 12 collides due to a human error in the program setting, the shield 12 will compress the elastic disc 27 to produce elastic deformation. At the same time, the elastic disc 27 will drive the hinge block 30 to move downward. The hinge block 30 will drive the abutment rod 34 to rotate, causing the abutment rod 34 to twist the torsion spring 33. The abutment rod 34 will drive the hinge block 35 to move downward, causing the hinge block 35 to slide relative to the damping plate 40. This can effectively buffer the shield 12 and prevent the impact generated during the collision from directly acting on the laser welding head 11 through the shield 12, thus providing good protection for the laser welding head 11.

S4: The spark blocked by the shield (12) will come into contact with the inner spiral heat exchange tube (23) inside it. The heat generated by the spark will be transferred to the inner spiral heat exchange tube (23) to heat the heat transfer oil of the inner spiral heat exchange tube (23). At the same time, the micro water pump (20) starts. S5: The micro water pump (20) transports the heated heat transfer oil in the inner spiral heat exchange tube (23) to the liquid guide tube (21) through the liquid suction tube (22), and then to the outer spiral heat exchange tube (14) through the liquid guide tube (21), so that heat accumulates inside the shell (13), and at the same time, multiple micro air pumps (16) are started. S6: The micro air pump (16) delivers the hot air inside the shell (13) to the air outlet pipe (18) through the air intake pipe (17), and then delivers it to the hollow ring plate (42) through the air outlet pipe (18), and finally sprays it out through the V-shaped nozzle (19). Since the V-shaped nozzle (19) is annular, it can generate an annular high-temperature air curtain. During the welding process, the laser welding head (11) blows this high-temperature air curtain towards the welding completed position to slowly cool it, effectively reducing the cooling rate and preventing the formation of hardened structure, thereby releasing welding stress. At the same time, it will also blow towards the position to be welded in advance, playing a role in preheating and cleaning the position to be welded, reducing the temperature difference gradient during welding. Meanwhile, the impact force of the airflow can also blow away the tiny floating dust on the surface to be welded, improving the welding quality. S7: When the shield (12) collides due to a human error in the program setting, the shield (12) will squeeze the elastic disk (27) to produce elastic deformation. At the same time, the elastic disk (27) will drive the hinge block (30) to move downward. The hinge block (30) will drive the abutment (34) to rotate, causing the abutment (34) to twist the torsion spring (33). The abutment (34) will drive the hinge block (35) to move downward, causing the hinge block (35) to slide relative to the damping plate (40). This will provide a good buffer for the shield (12) and prevent the impact generated during the collision from directly acting on the laser welding head (11) through the shield (12), thus providing good protection for the laser welding head (11).
