Description

Technical Field

[0001] This invention relates to the field of battery tray processing technology, and in particular to a battery tray processing equipment based on multi-station parallel laser welding. Background Technology

[0002] With the rapid development of the new energy vehicle industry, multi-station parallel laser welding has gradually become the mainstream process for the mass production of battery trays due to its advantages of high processing efficiency, concentrated heat input, and good weld formation quality. It can realize the simultaneous welding of multiple parts such as crossbeams and tray bottom plates, greatly shorten the processing cycle of a single piece, and meet the needs of mass production.

[0003] Existing processing equipment mostly uses air blowing or independent water cooling for welding heat dissipation. During the welding of the pallet base and crossbeams, the continuous action of the high-energy laser beam causes localized high temperatures in the pallet base and welding area. Heat accumulates rapidly and cannot be dissipated evenly, easily leading to localized thermal deformation and stress concentration in the pallet base. While some equipment is equipped with simple cooling structures, these are often single-pass cooling systems, unable to form a closed-loop circulation. Cooling water cannot be replaced and reused regularly, resulting in a continuous decline in cooling efficiency and difficulty in long-term stable suppression of thermal deformation. Simultaneously, conventional fixed cooling devices cannot keep pace, leading to delayed cooling of the weld seam and weld joint area, and the inability to eliminate thermal stress in a timely manner. Furthermore, the thin-plate crossbeams are prone to heat accumulation in multiple areas under high temperatures, easily causing warping and deformation. Relying solely on rigid clamps for restraint can easily cause scratches on the workpiece surface, requiring additional shaping processes and reducing overall processing efficiency. Therefore, how to provide a battery pallet processing equipment based on multi-station parallel laser welding is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] One objective of this invention is to provide a battery tray processing device based on multi-station parallel laser welding. This invention, by setting up a roller cooling assembly, through multiple sets of hinged installation structures and hollow copper cooling roller structures, can move synchronously with the welding mechanism, enabling real-time cooling of the weld area. This significantly reduces the thermal stress at the weld joint between the crossbeam and the tray bottom plate. Furthermore, through roller one and roller two, the crossbeam structure is adaptively fitted from the top and sides, providing flexible compression and anti-warping constraints while cooling, thus suppressing deformation and warping caused by welding from the source.

[0005] According to an embodiment of the present invention, a battery tray processing equipment based on multi-station parallel laser welding includes a cabinet, a worktable nested inside the cabinet, a gantry frame installed on both sides of the cabinet, a robotic arm module installed on the outer side of the gantry frame, a welding module installed at the bottom of the robotic arm module, an industrial camera installed on one side of the gantry frame, a tray base plate installed at the top of the worktable, and a crossbeam installed at the bottom of the tray base plate. The equipment also includes a conveying and cooling assembly installed inside the cabinet for actively cooling the bottom of the tray base plate, a roller cooling assembly installed on one side of the robotic arm module for cooling the outer side of the crossbeam and preventing warping during welding, and an auxiliary assembly installed on one side of the cabinet for assisted wiping of the contact portion of the roller cooling assembly.

[0006] Furthermore, the cooling conveying assembly includes a water tank, which is installed inside the cabinet. A one-way valve is installed on the surface of the water tank. The one-way valve is connected to a water pump via a pipeline. The water pump is installed inside the cabinet, and one end of the water pump is connected to a solenoid valve via a pipeline.

[0007] Furthermore, the solenoid valve is installed inside the cabinet, one end of the solenoid valve is connected to the cooling pipe through a pipeline, the cooling pipe is nested inside the workbench, the other end of the cooling pipe is connected to the solenoid valve through a pipeline, and one end of the solenoid valve is connected to the return box through a pipeline.

[0008] Furthermore, the return box is installed inside the cabinet, and a one-way valve is installed at one end of the return box. The end of the one-way valve is connected to one side of the water tank through a pipeline.

[0009] Furthermore, the roller cooling assembly includes a mounting frame 1, which is equidistantly distributed on one side of the robot module. One set of the mounting frames 1 has its ends connected to the side wall of the gantry frame by cylindrical pins. Multiple sets of the mounting frames 1 are provided, and two sets of the mounting frames 1 are connected to each other by a hinge plate pair 1.

[0010] Furthermore, each set of mounting frame one is equipped with a roller one on its inner side, and two mounting frames two are symmetrically arranged on both sides of each set of mounting frame one. The two mounting frames two are respectively connected to the mounting frame one through a hinge plate pair two. Each mounting frame two is equipped with a roller two on its inner side. The mounting frame one and the hinge plate pair one are nested together with a conveying pipe.

[0011] Furthermore, a delivery pipe is nested inside the second mounting bracket and the corresponding second hinge plate. Each delivery pipe is connected to the inner channel of the first mounting bracket and the second mounting bracket. One end of the delivery pipe is connected to one end of the solenoid valve through a flexible hose, and the other end of the delivery pipe is connected to a pressure sensor.

[0012] Furthermore, the auxiliary components include a fixing plate and a support frame, with the fixing plate mounted on the top of the workbench.

[0013] Furthermore, exhaust fans are equidistantly nested on the inner side of the fixing plate, and the support frame is installed on one side of the gantry frame.

[0014] Furthermore, two silicone scrapers are installed on one side of the support frame, and the two silicone scrapers are arranged parallel to each other. A recycling trough is installed on one side of the support frame.

[0015] The beneficial effects of this invention are: This invention, by setting up a conveying and cooling assembly, forms a closed-loop cooling cycle through a water tank, water pump, solenoid valve, and U-shaped cooling pipe. This enables continuous and uniform cooling of the contact surface of the worktable and the bottom of the tray base, significantly reducing the temperature of the welding area. Simultaneously, the solenoid valve automatically switches the path, enabling timed replacement and recycling of the cooling water, ensuring stable cooling efficiency. This ensures that the cooling process can suppress thermal deformation and stress concentration caused by localized high temperatures on the tray base, reducing the occurrence of damage to processed parts during laser welding.

[0016] This invention, by setting up a roller cooling assembly, with multiple sets of hinged installation structures and hollow copper cooling roller structures, can move synchronously with the welding mechanism, enabling real-time cooling of the weld area. This significantly reduces the thermal stress at the weld joint between the crossbeam and the pallet bottom plate. Furthermore, by using roller one and roller two to adaptively fit the crossbeam structure from the top and sides, it provides flexible compression and anti-warping constraints while cooling, thus suppressing deformation and warping caused by welding from the source.

[0017] This invention incorporates an exhaust fan to accelerate airflow on one side of the workbench, facilitating the removal of hot air accumulated in the hollow area inside the crossbeam. This further reduces welding heat accumulation and thermal deformation, and works in synergy with the roller cooling assembly to enhance efficiency.

[0018] This invention, by setting up an auxiliary component, uses a silicone scraper to perform flexible pre-cleaning on the surface of the rollers before they start working, effectively removing dust, debris and impurities. This avoids situations where foreign objects adhere to the surfaces of rollers 1 and 2 during the previous processing, causing the workpiece to be scratched when rollers 1 and 2 roll, or causing the mechanism to jam.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0030] refer to Figure 1 - Figure 10 The system includes a cabinet 1, with a workbench 2 nested inside the cabinet 1. The workbench 2 is made of thermally conductive material. A gantry frame 3 is installed on both sides of the cabinet 1. A robotic arm module 4 is installed on the outside of the gantry frame 3. A welding module 5 is installed at the bottom of the robotic arm module 4. An industrial camera 6 is installed on one side of the gantry frame 3. A pallet base plate 10 is installed on the top of the workbench 2. A crossbeam 11 is installed at the bottom of the pallet base plate 10. The system also includes a conveying and cooling assembly 7, which is installed inside the cabinet 1 and is used to actively cool the bottom of the pallet base plate 10. A roller cooling assembly 8 is installed on one side of the robotic arm module 4 and is used to cool the outside of the crossbeam 11 and prevent warping during welding. An auxiliary assembly 9 is installed on one side of the cabinet 1 and is used to assist in wiping the contact parts of the roller cooling assembly 8.

[0031] like Figures 2 to 4As shown, the conveying and cooling assembly 7 includes a water tank 71, which is installed inside the cabinet 1. A one-way valve 72 is installed on the surface of the water tank 71. The one-way valve 72 is connected to a water pump 73 via a pipeline. The water pump 73 is installed inside the cabinet 1. One end of the water pump 73 is connected to a solenoid valve 74 via a pipeline. The solenoid valve 74 is installed inside the cabinet 1. One end of the solenoid valve 74 is connected to a cooling pipe 75 via a pipeline. The cooling pipe 75 is nested inside the workbench 2. The cooling pipe 75 adopts a U-shaped design. The cooling pipe 75 is arranged in a shape to ensure sufficient contact area with the inner side of the workbench 2. The other end of the cooling pipe 75 is connected to the solenoid valve 74 through a pipe. One end of the solenoid valve 74 is connected to the return box 76 through a pipe. The return box 76 is installed inside the cabinet 1. The water tank 71 and the return box 76 are made of PE plastic, which has the characteristics of high temperature resistance and impact resistance, and is convenient for storing cooling water. One end of the return box 76 is equipped with a one-way valve 77. The end of the one-way valve 77 is connected to one side of the water tank 71 through a pipe.

[0032] In this implementation scheme, the operator can preset the cooling water replacement cycle and circulation parameters through the control module (marked in the figure). After the system has run for the preset time, the control module automatically issues a command to control the solenoid valve 74 to switch the flow path, allowing the cooling water in the cooling pipe 75 with increased temperature and decreased heat exchange efficiency to be temporarily stored and cooled in the return box 76 through the corresponding pipeline. Subsequently, the control module (marked in the figure) controls the solenoid valve 74 again to restore the water supply path and starts the water pump 73 to pump the cooler cooling water in the water tank 71 back into the cooling pipe 75. Under the driving force of the new cooling water, the high-temperature cooling water remaining in the cooling pipe 75 is continuously replaced, flowing along... The pipeline flows into the return tank 76 to realize the timed renewal of the cooling medium. When the cooling water stored in the return tank 76 reaches the preset capacity or upper limit of the liquid level, the cooling water in the return tank 76, under pressure, flows back to the water tank 71 through the one-way valve 77 and the corresponding pipeline on one side, and mixes with the low temperature cooling water in the water tank 71 to cool it down. The water tank 71 can be replenished with cooling water in real time through the external water source interface to make up for the loss in the circulation process and ensure the stability of the total amount of cooling medium in the system. The cooling water that flows back to the water tank 71 through the return tank 76 can participate in the circulation cooling again after being mixed and cooled in the water tank 71, and continue to efficiently cool the bottom of the tray bottom plate 10.

[0033] like Figures 5 to 7As shown, the roller cooling assembly 8 includes mounting brackets 81, which are equidistantly distributed on one side of the robot module 4. One set of mounting brackets 81 has its end connected to the side wall of the gantry 3 via cylindrical pins. Multiple sets of mounting brackets 81 are provided, and two sets are connected by a hinge plate 82. A roller 83 is mounted on the inner side of each set of mounting brackets 81. Two mounting brackets 84 are symmetrically arranged on both sides of each set of mounting brackets 81, and are connected to the mounting brackets 81 via hinge plates 85. A roller 86 is mounted on the inner side of each mounting bracket 84. Rollers 83 and 86 are made of copper and have a hollow interior. The hollow structure, hinge plate 82 and hinge plate 85 both adopt a two-way hinge design and are installed by means of pin engagement, which can adapt to the angle changes in the horizontal and small pitch directions. The inner side of mounting bracket 81 and hinge plate 82 is nested with a conveying pipe 87. The conveying pipe 87 is a flexible hose, which takes into account the versatility and is not easy to break when hinge plate 82 and hinge plate 85 rotate. The inner side of mounting bracket 84 is also nested with a conveying pipe 87. Each conveying pipe 87 is connected to the inner channel of mounting bracket 81 and mounting bracket 84 respectively. One end of the conveying pipe 87 is connected to one end of the solenoid valve 74 through a flexible hose, and the other end of the conveying pipe 87 is connected to a pressure sensor 88.

[0034] In this embodiment, while cooling the tray bottom plate 10, the control module (not shown in the figure) controls the solenoid valve 74 to switch the flow path, pumping the cooling water inside the water tank 71 into the three delivery pipes 87. Each delivery pipe 87 is connected to the internal channels of the corresponding mounting bracket 1 81 and mounting bracket 2 84, respectively delivering the cooling water into the corresponding roller 1 83 and roller 2 86. The pressure sensor 88 at the end of each delivery pipe 87 continuously records the pressure. When the pressure reaches the rated value, the input of cooling water into the delivery pipe 87 is stopped, ensuring that the cooling water circuit is in a stable working state, avoiding pipe leakage or damage to the internal structure of the rollers due to excessive pressure, and also ensuring that the cooling water can be evenly filled. The cooling chambers of roller 1 83 and roller 2 86 enable efficient and stable heat exchange in the welding area. During the following movement, the roller 1 83 installed at the bottom of multiple sets of mounting frames 1 81 will always remain in close contact with the outer surface of the crossbeam 11 under the weight of the mounting frame 1 81 itself and the flexible downward pressure of the hinge structure, without any problems such as suspension, warping, or excessive gaps. The mounting frames 2 84 on both sides will adjust their posture synchronously with the mounting frame 1 81 through the hinge plate pair 2 85, so that the roller 2 86 on the inner side of the mounting frame 2 84 can also be in close contact with the side wall of the crossbeam 11 and roll in an auxiliary manner as the roller 1 83 moves. This allows the roller 1 83 and roller 2 86 to cool the surface of the crossbeam 11 and prevent the crossbeam 11 from deforming due to heat.

[0035] like Figures 8 to 10 As shown, the auxiliary component 9 includes a fixed plate 91 and a support frame 93. The fixed plate 91 is installed on the top of the workbench 2. An exhaust fan 92 is nested equidistantly on the inner side of the fixed plate 91. The support frame 93 is installed on one side of the gantry frame 3. Two silicone scrapers 94 are installed on one side of the support frame 93. The two silicone scrapers 94 are arranged parallel to each other. A recycling tank 95 is installed on one side of the support frame 93. The recycling tank 95 is made of wear-resistant metal and is used to collect dust and fine impurities scraped off the surfaces of roller 1 83 and roller 2 86 by the silicone scrapers 94.

[0036] In this implementation scheme, the silicone scraper 94 can be used to perform flexible pre-cleaning on the surface of the rollers before they start working, effectively removing dust, debris and impurities. This avoids the situation where foreign objects adhere to the surfaces of roller 1 83 and roller 2 86 during the previous processing, causing the rollers to scratch the workpiece or cause the mechanism to jam. At the same time, the exhaust fan 92 located inside the fixed plate 91 is controlled by the control module (not marked in the figure) to rotate, accelerating the airflow on one side of the equipment. This also removes the hot air accumulated in the hollow structure inside the crossbeam 11, further reducing the occurrence of heat deformation of the crossbeam 11.

[0037] Working principle: The operator first places the pallet base plate 10 on the workbench 2, aligning one side of the pallet base plate 10 with and tightly adhering to the fixing plate 91, which facilitates the operator's positioning of the pallet base plate 10 before processing. Then, the pallet base plate 10 is clamped and fixed using a fixture (not marked in the figure). Next, the crossbeam 11 is placed at the top of the pallet base plate 10 according to the drawing markings to ensure accurate positioning before welding. The equipment is controlled by the control module (not marked in the figure) to start the welding process. The robotic arm module 4 moves the welding module 5 on the gantry 3 to perform laser welding. The welding module 5 has two welding guns symmetrically arranged for synchronous welding. During the processing, the industrial camera 6 located on one side of the gantry 3 is used to monitor the processing status. When welding is performed by welding module 5, the movement of robot module 4 on gantry 3 drives the movement of mounting frame 81 connected to robot module 4. Multiple sets of mounting frames 81 are flexibly linked through hinge plate pair 82. The connection between adjacent mounting frames 81 is ensured by the combination of pins, and an appropriate range of movement is reserved to adapt to the angle fine adjustment requirements under different displacement trajectories. There will be no problems of structural jamming or pulling deformation. At the same time, the left and right sides of each set of mounting frames 81 are symmetrically connected to the corresponding mounting frame 84 through hinge plate pair 85, forming an overall transmission frame with robot module 4 as the core power end and multiple sets of mounting frames 81 and mounting frame 84 linked together. This enables the single power of robot module 4 to drive the synchronous displacement of multiple auxiliary structures. The water pump 73 and solenoid valve 74 are controlled in coordination by the control module (not shown in the figure). The solenoid valve 74 is used to switch the flow path of the cooling medium. During the laser welding operation, the control module drives the water pump 73 to start, and the cooling water stored in the water tank 71 is stably delivered to the inside of the cooling pipe 75 through the one-way valve 72, so that a continuous cooling cycle is formed in the cooling pipe 75. Thus, during the laser welding process, the bottom of the tray base plate 10 is cooled in real time and uniformly, which effectively reduces the temperature of the welding area, suppresses the thermal deformation and stress concentration of the tray base plate 10 caused by local high temperature, and ensures welding accuracy and structural stability. The operator can preset the replacement cycle and circulation parameters of the cooling water through the control module (not marked in the figure). After the system has run for a preset time, the control module (not marked in the figure) automatically issues a command to control the solenoid valve 74 to switch the flow path, and guide the cooling water in the cooling pipe 75 with the temperature rising and the heat exchange efficiency decreasing into the return box 76 through the corresponding pipeline for temporary storage and cooling. Then the control module (not marked in the figure) controls the solenoid valve 74 again to restore the water supply path and starts the water pump 73 to pump the cooling water with the lower temperature in the water tank 71 back into the cooling pipe 75. Driven by the new cooling water, the high-temperature cooling water remaining inside the cooling pipe 75 is continuously replaced and flows into the return tank 76 along the pipeline, realizing the timed renewal of the cooling medium. When the cooling water stored in the return tank 76 reaches the preset capacity or upper limit of the liquid level, the cooling water in the return tank 76, under pressure, flows back to the water tank 71 through the one-way valve 77 and the corresponding pipeline, and mixes with the low-temperature cooling water in the water tank 71 to cool it down. The water tank 71 can be replenished with cooling water in real time through the external water source interface to make up for the loss in the circulation process and ensure the stability of the total amount of cooling medium in the system. The cooling water that flows back to the water tank 71 through the return tank 76 can participate in the circulation cooling again after being mixed and cooled down in the water tank 71, and continue to efficiently cool the bottom of the tray bottom plate 10. While cooling the tray bottom plate 10, the control module (not shown in the figure) controls the solenoid valve 74 to switch the flow path, and pumps the cooling water inside the water tank 71 into the three delivery pipes 87. Each delivery pipe 87 is connected to the internal channels of the corresponding mounting bracket 1 81 and mounting bracket 2 84, and delivers the cooling water to the corresponding roller 1 83 and roller 2 86 respectively. The pressure sensor 88 at the end of each delivery pipe 87 will continuously record the pressure. When the pressure reaches the rated value, the input of cooling water into the delivery pipe 87 will stop, ensuring that the cooling water circuit is in a stable working state, avoiding pipeline leakage or damage to the internal structure of the rollers due to excessive pressure. At the same time, it can also ensure that the cooling water can evenly fill the cooling chambers of roller 1 83 and roller 2 86, achieving efficient and stable heat exchange in the welding area. When the welding module 5 performs laser welding on the angle between the crossbeam 11 and the pallet base plate 10 on the workpiece, multiple sets of mounting frames 81 move synchronously with the welding module 5. The rollers 83 installed at the bottom of the multiple sets of mounting frames 81 will first come into contact with the surface of the multiple sets of silicone scrapers 94 under the weight of the mounting frame 81 itself and the flexible downward pressure of the hinge structure. The silicone scrapers 94 pre-clean the outer circumference of the rollers 83 and 86 in a flexible bonding manner, effectively scraping off the dust, small impurities and processing residues attached to the surface of the rollers 83 and 86. The scraped impurities fall naturally into the recycling tank 95 located on one side of the support frame 93 under the action of gravity and are collected in a centralized manner for easy cleaning and treatment later. Thus, through continuous cleaning and flexible pressing structure, surface scratches, movement jamming or positioning deviation caused by impurities are avoided, providing a stable and reliable motion foundation for subsequent processing, assembly or inspection processes. After cleaning rollers 83 and 86, the rollers 83 installed at the bottom of the multiple sets of mounting frames 81 will remain in close contact with the outer surface of the crossbeam 11 under the weight of the mounting frame 81 itself and the flexible downward pressure of the hinge structure. There will be no problems such as suspension, warping, or excessive gaps. The mounting frames 84 on both sides will adjust their posture synchronously with the mounting frame 81 through the hinge plate pair 85, so that the rollers 86 on the inner side of the mounting frame 84 can also be in close contact with the side wall of the crossbeam 11 and roll in an auxiliary manner as the rollers 83 move. This allows the rollers 83 and 86 to cool the surface of the crossbeam 11 and prevent the crossbeam 11 from deforming due to heat. At the same time, the exhaust fan 92 located inside the fixed plate 91 is controlled by the control module (not marked in the figure) to rotate, which accelerates the airflow on one side of the equipment and can also remove the hot air accumulated in the hollow structure inside the crossbeam 11, further reducing the occurrence of heat deformation of the crossbeam 11. As rollers 83 and 86 move synchronously along the welding path, they continuously and rapidly dissipate the high heat generated in the welding area of ​​the crossbeam 11 through internal circulating cooling water, achieving synchronous cooling with the welding module 5. This effectively reduces the peak temperature at the welding joint between the crossbeam 11 and the pallet bottom plate 10, minimizing the concentration of temperature and thermal stress. It can suppress welding deformation, warping, and residual stress from the source. At the same time, rollers 83 and 86 provide multi-faceted adaptive pressing and guiding for the crossbeam 11, ensuring that the crossbeam 11 remains stable and does not shift during the entire welding process, while also applying appropriate constraints to the surrounding area of ​​the weld, further improving the welding forming accuracy and structural dimensional stability.
