Description

Technical Field

[0001] The present invention relates to the technical field of battery tray welding, and in particular to battery tray welding equipment based on a deformation correction structure. Background Art

[0002] The core of new energy electric vehicles lies in the automotive power battery, which belongs to the broad category of chemical batteries and is mainly divided into the following three categories: primary batteries, also called dry batteries, which are non-rechargeable, such as the common alkaline batteries in life; secondary batteries, that is, rechargeable batteries. The basic requirement that automotive power batteries must meet is rechargeability; fuel cells, whose positive and negative electrodes themselves do not contain active substances, and active materials are continuously added from the outside, such as hydrogen fuel cells.

[0003] In new energy vehicles, batteries are loaded onto trays, which are then mounted on the vehicle to provide the power needed for driving. For example, a welding and fastening device for producing battery trays, disclosed in publication number CN117961354A, employs a fastening frame that slides within a processing table and utilizes the weight of the battery tray to compress a pressure plate and move a clamping block in conjunction, thereby clamping and fixing the battery tray's edges. However, this fixing method is only applicable when the pressure plate is located below the battery tray, and the deflection angle of the fastening frame should not be too large. Once the deflection angle of the fastening frame is too large, the weight of the battery tray mainly acts on the clamping block at the lowest point, thereby causing the pressure plate to move and cause the battery tray to partially push out of the fastening frame. When flipping 180°, the weight of the battery tray cannot act on the pressure plate, making it difficult to achieve effective and stable fixing at large angles. This causes the placement of the battery tray to deviate, making it difficult to achieve high-precision welding. A solution is now proposed. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1-Figure 7 As shown, the problem that it is difficult to effectively and stably fix the battery tray during large-angle deflection welding in the prior art, resulting in position deviation during deflection welding and the inability to achieve high-precision welding processing, can be solved by the following solution; The battery tray welding device based on the deformation correction structure in this embodiment includes a mounting base 1 and a flip-type fixing assembly 2 provided on the mounting base 1 for correcting and clamping the battery tray. The flip-type fixing assembly 2 includes two sets of rotating rings 21. A conveying assembly 2 3 for correcting the deviation of the battery tray is provided between the rotating rings 21. Conveying assemblies 1 4 and 3 5 with the same structure are provided on both sides of the mounting base 1 respectively. The conveying assembly 1 4, the conveying assembly 2 3 and the conveying assembly 3 5 can realize the automatic loading and unloading welding processing of the battery tray, further improving the convenience of the welding process, and the conveying assembly 2 3 cooperates with the flip-type fixing assembly 2 to realize the single-side extrusion fixing processing of the battery tray; The mounting base 1 is provided with a welding robot arm 11 for cooperating with a flip-type fixing component 2 to perform multi-angle welding on the battery tray. The flip-type fixing component 2 drives the battery tray to deflect at any angle, thereby achieving stable fixation while achieving multi-angle welding processing.

[0021] The rotating ring 21 is rotatably mounted on the top of the mounting base 1, and a gear ring is fixedly connected to the outer wall of the rotating ring 21. A rotating rod is rotatably connected to the mounting base 1, and a gear meshing with the corresponding gear ring is fixedly connected to the rotating rod. A first servo motor that drives the rotating rod to rotate is installed on the mounting base 1. During the welding process, the rotating rod is driven to rotate by the first servo motor, and the meshing of the gears on both sides with the corresponding gear rings drives the fixed battery tray to deflect, and cooperates with the welding robot arm 11 to realize multi-angle welding processing.

[0022] A movable frame 22 is provided between the rotating rings 21. An electric push rod 23 and a guide sleeve are fixedly installed between the movable frame 22 and the corresponding rotating ring 21. The guide sleeve is used to further limit the stability of the moving direction of the movable frame 22. The movable frame 22 is provided with a plurality of correction blocks 24 adapted to the side walls of the battery tray; The movable frame 22 is driven to move by an electric push rod 23. The movable frame 22 carries a plurality of adaptive correction blocks 24 to engage with the side walls of the battery tray. While achieving stable press-fit fixation of the battery tray, it can also assist in correcting the deformed side walls of the tray, thereby improving the welding quality.

[0023] The movable frame 22 is slidably connected to a plurality of adjustment plates 25 distributed in a mouth shape, which are used to perform correction and fixation on all four side walls of the battery tray. The movable frame 22 is threaded with bolts that interfere with corresponding adjustment plates 25. By moving the adjustment plates 25 and locking their positions with the bolts, the positions of the plurality of correction blocks 24 can be changed, thereby adapting to the correction and fixation of battery trays of different sizes. An L-shaped seat 26 is fixedly connected to the adjustment plate 25, and a pillar 27 connected to the corresponding correction block 24 by bolts is slidably installed on the L-shaped seat 26. The correction block 24 can be disassembled and installed, and an appropriate correction block 24 can be selected according to the shape of the side wall of the battery tray, thereby improving the deformation correction effect.

[0024] A second electric push rod 28 is fixedly mounted on the L-shaped seat 26. A plurality of adaptive correction blocks 24 are independently controlled by the corresponding second electric push rod 28. This allows the welding robot arm 11 to individually deflect away from the welding area without affecting welding stability during the welding process of the battery tray, thereby optimizing the space expansion of the welding area. The end of the second electric push rod 28 is rotatably connected to the support 27. An L-shaped guide groove 29 is provided on the L-shaped seat 26. A guide pin 1 210 and a guide pin 211 are fixedly connected to the support 27 and are slidably connected to the guide groove 29. The first electric push rod 23 is combined with the guide sleeve to push the movable frame 22 downward, causing the multiple correction blocks 24 distributed in a mouth shape on the movable frame 22 to move downward. Until the multiple correction blocks 24 are engaged with the side walls around the battery tray, combined with the support of the multiple conveying rollers 32, the battery tray is adaptively squeezed and fixed. With the help of the multiple correction blocks 24 engaging the side walls of the battery tray, the deformed side walls can be corrected simultaneously, and then the battery tray is welded by the welding robot arm 11; During the welding process, the push rod corresponding to the electric push rod 28 carries the pillar 27 to extend and move, and the L-shaped guide groove 29 guides the guide pin 1 210 and the guide pin 2 211, causing the pillar 27 to carry the correction block 24 to separate from the battery tray. Later, when the guide pin 211 enters the oblique section of the L-shaped guide groove 29, the pillar 27 carrying the correction block 24 is caused to deflect, and then move away from the welding area of ​​the battery tray of the welding robot arm 11, thereby optimizing the space expansion of the welding area and quickly completing the concession welding process.

[0025] The conveying component 2 3 includes a fixed frame 31 fixedly connected between the rotating rings 21, and a plurality of conveying rollers 32 are equidistantly connected in rotation in the fixed frame 31. Sprockets are fixedly installed on the roller shafts on both sides of the conveying rollers 32. The sprockets on the two adjacent groups of conveying rollers 32 are connected by chain transmission. A second servo motor that drives the corresponding conveying rollers 32 to rotate is installed on the fixed frame 31. The second servo motor drives the corresponding conveying rollers 32 to rotate, and combined with the transmission of the corresponding sprockets and chains, drives the multiple conveying rollers 32 to rotate synchronously and in the same direction, and conveys the welded battery tray to the conveying component 3 5, and automatically discharges and conveys it through the conveying component 3 5.

[0026] The conveying assembly 1 4 includes a mounting frame 41 provided on one side of the mounting base 1. A plurality of conveying rollers 42 are equidistantly connected to the mounting frame 41 for rotation. Sprockets are fixedly mounted on the roller shafts on both sides of the conveying rollers 42. The sprockets on two adjacent groups of conveying rollers 42 are connected by a chain transmission. A third servo motor is mounted on the mounting frame 41 to drive the corresponding conveying rollers 42 to rotate. When loading, the third servo motor in the conveying component 1 4 drives the corresponding conveying roller 42 to rotate, and combined with the transmission of the corresponding sprocket and chain, drives multiple conveying rollers 42 to rotate synchronously and in the same direction, and loads and conveys the battery tray placed on the conveying component 1 4. When unloading, the third servo motor in the conveying component 3 5 drives the corresponding conveying roller 42 to rotate, driving the welded battery tray to be output.

[0027] Example 2: Please refer to Figure 1 、 Figure 5 、 Figure 7 and Figure 8 As shown, the following solutions can be used to position and transport battery trays of different sizes to ensure accurate fixation and deformation correction of the battery trays; In this embodiment, the top of the correction block 24 located on the long side of the movable frame 22 is rotatably connected to a plurality of auxiliary rollers. During the welding process, when the battery tray needs to be moved a short distance, the electric push rod 28 located on the front and rear sides of the battery tray is controlled to drive the correction block 24 to deflect away, and the second servo motor drives the plurality of conveying rollers 32 to rotate, and the battery tray moves a short distance. The correction block 24 located on the long side of the movable frame 22 indirectly contacts the battery tray through the auxiliary rollers, thereby achieving stable fixed processing during the short-distance movement.

[0028] The two sides of the conveying roller 32 are symmetrically and slidably connected to guide plates 33 with a frustum-shaped cross section. Bolts that come into contact with the conveying roller 32 are threadedly connected to the guide plates 33. The guide plates 33 on multiple groups of conveying rollers 32 are distributed in a trumpet shape. When the battery tray moves on the top of the fixed frame 31, the battery tray is first pushed step by step to correct the deviation and be transported in the center through the guide plates 33 distributed in an eight shape on several conveying rollers 32 located on one side of the conveying component 1 4, and then the centering transportation is maintained by the guide plates 33 distributed in an equal shape on several conveying rollers 32 located on one side of the conveying component 3 5. This can realize anti-deviation and centering transportation of the moving battery tray, and the positioning and conveying effect of battery trays of different sizes can be achieved through the guide plates 33 with adjustable spacing on the conveying rollers 32.

[0029] A mounting block 212 is bolted to one side of the bottom of the movable frame 22 near the conveying assembly 3 5. A photoelectric sensor is embedded in the mounting block 212. A control panel 12 is fixedly mounted on the mounting base 1. The position of the battery tray is collected by the photoelectric sensor on the mounting block 212 until one side of the battery tray moves to directly below the photoelectric sensor. The photoelectric sensor transmits the collected control signal to the controller in the control panel 12. The controller generates a stop signal to control the second servo motor and the third servo motor to stop rotating, further completing the positioning and transportation of the battery tray, ensuring the precise engagement of multiple correction blocks 24 with the battery tray, and achieving accuracy in fixing and correcting the deformation of the battery tray.

[0030] Example 3: Please refer to Figures 1-8 As shown, the present invention also proposes a method for using a battery tray welding device based on a deformation correction structure, comprising the following steps: Step 1: The third servo motor drives the corresponding conveyor roller 42 to rotate. Combined with the transmission of the corresponding sprocket and chain, the multiple conveyor rollers 42 are driven to rotate synchronously and in the same direction to load the battery tray placed on the conveyor assembly 1 4. The second servo motor drives the corresponding conveyor roller 32 to rotate. Combined with the transmission of the corresponding sprocket and chain, the multiple conveyor rollers 32 are driven to rotate synchronously and in the same direction to load the battery tray between the fixed frame 31 and the movable frame 22. Step 2: As the battery tray moves on the fixed frame 31, the battery tray is first pushed step by step to correct its deviation and be transported in the center by the guide plates 33 distributed in an eight shape on the several conveying rollers 32 located on one side of the conveying component 1 4. Then, the battery tray is kept in the center by the guide plates 33 distributed in an equal shape on the several conveying rollers 32 located on one side of the conveying component 3 5. The position of the battery tray is then detected by the photoelectric sensor on the mounting block 212 until one side of the battery tray moves directly under the photoelectric sensor. The photoelectric sensor transmits the detected control signal to the controller in the control panel 12. The controller generates a stop signal to control the second servo motor and the third servo motor to stop rotating, thereby completing the positioning and transportation of the battery tray. Step 3: The electric push rod 1 23 is combined with the guide sleeve to push the movable frame 22 downward, causing the multiple correction blocks 24 distributed in a mouth shape on the movable frame 22 to move downward until the correction blocks 24 are engaged with the side walls of the battery tray. Combined with the support of the multiple conveyor rollers 32, the battery tray is adaptively squeezed and fixed. With the help of the multiple correction blocks 24 engaging the side walls of the battery tray, the deformed side walls can be corrected simultaneously. The battery tray is then welded by the welding robot arm 11. Step 4: During the welding process, the first servo motor drives the rotating rod to rotate, and the gear engages with the gear ring, causing the fixed battery tray to deflect and perform multi-angle welding. In addition, the push rod of the corresponding electric push rod 28 carries the pillar 27 to extend and move, and the L-shaped guide groove 29 guides the guide pin 1 210 and the guide pin 211, causing the pillar 27 to carry the correction block 24 and separate from the battery tray. The guide pin 211 then enters the oblique section of the L-shaped guide groove 29, causing the pillar 27 to carry the correction block 24 and deflect away from the welding area of ​​the battery tray by the welding robot arm 11, thereby quickly completing the full welding process; Step 5: When the guide plate 33 blocks the welding area of ​​the battery tray, the correction blocks 24 located at the front and rear sides of the moving battery tray are controlled to deflect away. The second servo motor drives the multiple conveyor rollers 32 to rotate, causing the fixed battery tray to move a short distance, exposing the welding area and assisting the welding robot arm 11 to complete the welding process. Step 6: After welding is completed, the electric push rod 23 drives the movable frame 22 to move away from the battery tray and reset. The second servo motor drives the conveying roller 32 to rotate, and the welded battery tray is conveyed to the conveying component 3 5, and the conveying component 3 5 is used for automatic discharge and conveying.
