Description

Technical Field

[0001] The present invention belongs to the technical field of battery frame processing, and specifically relates to a punching and welding composite processing equipment for a battery frame of a new energy vehicle. Background Art

[0002] The battery frame of a new energy vehicle (NEV) is a structural component used to support and protect the battery pack, typically made of metal or composite materials. Its primary function is to ensure stable and secure positioning of the battery cells during vehicle operation, while also providing the necessary mechanical strength and impact resistance. Battery frame design must consider not only structural strength but also heat dissipation, lightweight construction, and protective properties. Battery frames are primarily manufactured using a composite punching and welding process, combining edge welding and punching.

[0003] Conventional punching and welding composite processing equipment for battery frames mainly consists of two parts: a frame fixing component and a punching and welding component. When in use, the battery frame needs to be connected to the fixing component to complete the fixation of the battery frame. However, the fixing method currently used is screw locking. This fixing method requires frequent loosening and fixing of the battery frame when processing different sides of the battery frame, resulting in a long overall clamping time, affecting processing efficiency. At the same time, it is not compatible with the external clamping fixation and internal support fixation of the battery frame.

[0004] At the same time, after completing the clamping of the battery frame, the punching and welding components need to be positioned between the battery frame before the side of the battery frame can be punched and welded. This operation method requires a lot of preparation time when facing the welding of batch battery frames before the punching and welding process can be realized. The overall processing time is long and urgently needs to be improved. Summary of the Invention

[0005] The purpose of the present invention is to provide a new energy vehicle battery frame punching and welding composite processing equipment to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new energy vehicle battery frame punching and welding composite processing equipment, comprising a frame and transverse guide rails installed on the top of the frame near the four corners, and a movable frame arranged directly below the frame, a main cylinder is fixedly installed in the middle of the bottom end of the frame, the output end of the main cylinder is connected to the middle of the top of the movable frame, linkage components are installed at the top of the movable frame near the four corners, the top of the linkage component is movably connected to the transverse guide rail, the top of the linkage component is installed with a self-clamping component, a punching and welding component is movably installed on one side between the two front and rear self-clamping components, and the punching and welding component is magnetically connected to the self-clamping component;

[0007] The length of the main cylinder is adjusted to drive the movable frame to move up and down, and the displacement of the self-clamping component relative to the transverse guide rail is achieved through the action of the linkage component.

[0008] Before performing the punching and welding composite processing of the battery frame, the battery can be placed on top of the rack, and the battery frame can be kept close to the four corners and located directly above the trapezoidal block to complete the preliminary preparation before the composite processing.

[0009] As a further technical solution of the present invention, the linkage assembly includes a first fixed seat, the bottom end of the first fixed seat is connected to the top end of the movable frame, the end of the first fixed seat away from the movable frame is movably connected to a connecting rod through a rotating shaft, and the end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat through a rotating shaft.

[0010] As a further technical solution of the present invention, the top end of each second fixing seat is fixedly connected with a guide block, the guide block is movably connected to the transverse guide rail, and the top end of the guide block is connected to the bottom end of the self-clamping assembly.

[0011] Before starting the composite processing, the main cylinder can be turned on and controlled to extend. At this time, the length of the main cylinder increases, and at the same time, the movable frame at the bottom is driven to move downward. At this time, the distance between the movable frame and the frame increases. At this time, the first fixed seat drops and drives multiple connecting rods to deflect toward the middle of the movable frame. Under the guidance of the guide block and the transverse guide rail, multiple self-clamping components are driven to approach each other until the four corners of the battery frame are fixed by the self-clamping components.

[0012] By utilizing the coordination between the movable frame and the linkage assembly, and the coordination between the linkage assembly and the self-clamping assembly, after the battery frame is placed in place, the battery frame can be quickly clamped and released by controlling the extension or shortening of the main cylinder. The whole process can be completed quickly. When processing batch battery frames, the preparation time can be significantly shortened, the clamping time can be reduced, and the overall processing efficiency can be improved.

[0013] As a further technical solution of the present invention, the self-clamping assembly includes a trapezoidal block, the bottom end of the trapezoidal block is connected to the top end of the guide block, a horizontal slot is provided on the side of the trapezoidal block, an adjustment frame is movably connected to the outer side of the horizontal slot, and the adjustment frame is displaced left and right relative to the trapezoidal block, and a micro push rod is built into the interior of the horizontal slot and is connected to the adjustment frame.

[0014] As a further technical solution of the present invention, longitudinal card slots are provided at both the front and rear ends of the adjusting frame, a clamping frame is provided on the outer side of the adjusting frame, and longitudinal card blocks are fixedly installed on both the front and rear ends of the inner side of the clamping frame. The clamping frame is movably connected between the longitudinal card blocks and the longitudinal card slots, and the clamping frame moves up and down relative to the adjusting frame.

[0015] As a further technical solution of the present invention, a reset spring is fixedly installed at the top of the inner cavity of the longitudinal slot, the bottom end of the reset spring is connected to the top of the longitudinal block, and a clamping plate is fixedly installed at the top of the clamping frame.

[0016] As a further technical solution of the present invention, an electromagnet is fixedly installed in the middle of the bottom end of the inner cavity of the clamping frame. When the electromagnet and the bottom end of the adjustment frame are attracted to each other, the reset spring is in an extreme compression state and the clamp is at the highest point.

[0017] When processing the inner side of the battery frame and clamping the outer side, the micro push rod inside the horizontal card slot can be opened to push the adjustment frame to move relative to the trapezoidal block until the inner side of the adjustment frame is against the outer side of the battery frame, and the power of the electromagnet can be turned on to adsorb the bottom end of the adjustment frame. At this time, the reset spring is compressed and drives the clamping frame and the clamping plate to move up until the inner side of the clamping plate contacts the outer side of the battery frame. At this time, the outer clamping process of the battery frame can be realized by the external clamping force of multiple clamping plates.

[0018] When the outer side of the battery frame needs to be processed, that is, when the inner side is clamped, the battery frame is briefly lifted up and the power of the electromagnet is turned off. The splint is lowered under the action of the reset spring and adjusted to the inner side of the battery frame by the micro push rod. The electromagnet is turned on again to move the splint upward, and the main cylinder is turned on to shorten the main cylinder, thereby achieving the relative distance between the multiple splints, applying thrust to the inner side of the battery frame through the outer sides of the multiple splints, and completing the internal support process.

[0019] By reusing the coordination between the main cylinder, linkage assembly and self-clamping assembly, and by moving the clamping plate left and right and up and down, the switching between different clamping states can be achieved. Through the action of the main cylinder and linkage assembly, the device can quickly switch from an external clamping state to an internal supporting state. The entire switching process can be completed quickly, allowing the device to adapt to the punching and welding processing requirements in different positions, thereby improving processing efficiency.

[0020] As a further technical solution of the present invention, the punching and welding assembly includes an adjusting guide rail, one side of the adjusting guide rail is adsorbed and connected to the clamping frame, a screw rod is movably installed inside the adjusting guide rail, the screw rod rotates relative to the adjusting guide rail, and a mounting block is threadedly sleeved on the outer side surface of the screw rod, and the mounting block is movably clamped to the adjusting guide rail.

[0021] As a further technical solution of the present invention, a servo motor is fixedly installed on one side of the adjustment guide rail, the output end of the servo motor is connected to one end of the screw rod, and a puncher and a welding head are symmetrically installed on one side of the mounting block.

[0022] When the outer clamping or inner support of the battery frame is completed, the punching and welding assembly is always located on one side of the two self-clamping assemblies, and the punching and welding assembly can be selectively installed on the left or right side of the self-clamping assembly as needed, that is, automatic positioning is completed. At this time, by adjusting the height of the adjustment guide rail, the welding head and the puncher reach the specified processing position, and the servo motor is turned on to drive the screw to rotate, and drive the mounting block to move relative to the adjustment guide rail, and the welding head and puncher are used to perform linear welding and linear punching on the specified position of the battery frame to complete the rapid punching and welding operation.

[0023] By adjusting the process of multiple self-clamping components and utilizing the cooperation between the self-clamping components and the punching and welding components, the punching and welding components can be automatically positioned quickly through the adjustment and clamping action of the self-clamping components, so that the punching and welding components correspond to the processing position of the battery frame no matter which side of the self-clamping component they are installed on. At the same time, the punching and welding components can directly provide linear processing, quickly process both sides of the battery frame, and can quickly complete the processing of the four sides of the battery frame only by switching the clamping position, significantly reducing preparation time and improving overall processing efficiency.

[0024] The beneficial effects of the present invention are as follows:

[0025] (1) The present invention utilizes the cooperation between the movable frame and the linkage assembly, and the cooperation between the linkage assembly and the self-clamping assembly, so that after the battery frame is placed in place, the battery frame can be quickly clamped and released by controlling the extension or shortening of the main cylinder. The whole process can be completed quickly. When processing batches of battery frames, the preparation time can be significantly shortened, the clamping time can be reduced, and the overall processing efficiency can be improved.

[0026] (2) The present invention reuses the cooperation between the main cylinder and the linkage assembly and the self-clamping assembly, and realizes switching between different clamping states through the left and right displacement and the up and down displacement of the clamping plate. The main cylinder and the linkage assembly enable the device to quickly switch from the external clamping state to the internal supporting state. The entire switching process can be completed quickly, so that the device can adapt to the punching and welding processing requirements in different positions, thereby improving processing efficiency.

[0027] (3) The present invention utilizes the adjustment process of multiple self-clamping components and the cooperation between the self-clamping components and the punching and welding components, and automatically realizes the rapid positioning of the punching and welding components through the adjustment and clamping action of the self-clamping components, so that the punching and welding components correspond to the processing position of the battery frame no matter which side of the self-clamping component they are installed on. At the same time, the punching and welding components can directly provide linear processing, quickly process both sides of the battery frame, and can quickly complete the processing of the four sides of the battery frame only by switching the clamping position, which significantly reduces the preparation time and improves the overall processing efficiency.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] like Figures 1 to 7As shown, in the embodiment of the present invention, a new energy vehicle battery frame punching and welding composite processing equipment includes a frame 1 and a transverse guide rail 2 installed on the top of the frame 1 near the four corners, and a movable frame 4 arranged directly below the frame 1. A main cylinder 3 is fixedly installed in the middle of the bottom end of the frame 1, and the output end of the main cylinder 3 is connected to the middle of the top of the movable frame 4. Linkage components 5 are installed on the top of the movable frame 4 near the four corners. The top of the linkage component 5 is movably connected to the transverse guide rail 2. The top of the linkage component 5 is installed with a self-clamping component 6. A punching and welding component 7 is movably installed on one side between the two front and rear self-clamping components 6. The punching and welding component 7 is magnetically connected to the self-clamping component 6.

[0038] The length adjustment of the main cylinder 3 drives the movable frame 4 to move up and down, and the linkage assembly 5 realizes the displacement of the self-clamping assembly 6 relative to the transverse guide rail 2.

[0039] Before performing the punching and welding composite processing of the battery frame, the battery can be placed on top of the rack 1, and the battery frame can be kept close to the four corners and located directly above the trapezoidal block 601 to complete the preliminary preparation before the composite processing.

[0040] like Figure 1 and Figure 3 As shown, the linkage assembly 5 includes a first fixed seat 501, the bottom end of the first fixed seat 501 is connected to the top of the movable frame 4, the end of the first fixed seat 501 away from the movable frame 4 is movably connected to the connecting rod 503 through a rotating shaft, the end of the connecting rod 503 away from the first fixed seat 501 is movably connected to the second fixed seat 502 through a rotating shaft, the top of the second fixed seat 502 is fixedly connected to a guide block 504, the guide block 504 is movably clamped with the transverse guide rail 2, and the top of the guide block 504 is connected to the bottom end of the self-clamping assembly 6.

[0041] Embodiment: Before starting the composite processing, the main cylinder 3 can be turned on and controlled to extend. At this time, the length of the main cylinder 3 increases accordingly, and at the same time, the movable frame 4 at the bottom is driven to move downward. At this time, the distance between the movable frame 4 and the frame 1 increases accordingly. At this time, the first fixed seat 501 drops accordingly, and drives multiple connecting rods 503 to deflect toward the middle direction of the movable frame 4. Under the guidance of the guide block 504 and the transverse guide rail 2, multiple self-clamping components 6 are driven to approach each other until the four corners of the battery frame are fixed by the self-clamping components 6.

[0042] By utilizing the cooperation between the movable frame 4 and the linkage component 5, and the cooperation between the linkage component 5 and the self-clamping component 6, after the battery frame is placed in place, the battery frame can be quickly clamped and released by controlling the extension or shortening of the main cylinder 3. The whole process can be completed quickly. When processing batch battery frames, the preparation time can be significantly shortened, the clamping time can be reduced, and the overall processing efficiency can be improved.

[0043] like Figure 1 and Figure 5 as well as Figure 6 and Figure 7 As shown, the self-clamping assembly 6 includes a trapezoidal block 601, the bottom end of the trapezoidal block 601 is connected to the top of the guide block 504, a horizontal card slot 602 is provided on the side of the trapezoidal block 601, and an adjustment frame 603 is movably connected to the outer side of the horizontal card slot 602. The adjustment frame 603 moves left and right relative to the trapezoidal block 601, and a micro push rod is built into the interior of the horizontal card slot 602 and is connected to the adjustment frame 603. The front and rear ends of the adjustment frame 603 are provided with longitudinal card slots 604, the outer side of the adjustment frame 603 is provided with a clamping frame 605, and the front and rear ends of the inner side of the clamping frame 605 are fixedly installed with longitudinal card blocks 6 06. The clamping frame 605 is movably connected between the longitudinal clamping block 606 and the longitudinal clamping slot 604. The clamping frame 605 moves up and down relative to the adjusting frame 603. The top of the inner cavity of the longitudinal clamping slot 604 is fixedly installed with a reset spring 607. The bottom end of the reset spring 607 is connected to the top of the longitudinal clamping block 606. The top of the clamping frame 605 is fixedly installed with a splint 608. The middle part of the bottom end of the inner cavity of the clamping frame 605 is fixedly installed with an electromagnet 609. When the electromagnet 609 and the bottom end of the adjusting frame 603 are attracted to each other, the reset spring 607 is in an extreme compression state, and the splint 608 is at the highest point.

[0044] In the initial state, that is, when the return spring 607 is in the initial state, the clamping frame 605 and the clamping plate 608 are at the lowest point, and the electromagnet 609 is located directly below the adjustment frame 603.

[0045] Embodiment: When processing the inner side of the battery frame and clamping the outer side, the micro push rod inside the horizontal slot 602 can be opened to push the adjustment frame 603 to move relative to the trapezoidal block 601 until the inner side of the adjustment frame 603 is against the outer side of the battery frame, and the power supply of the electromagnet 609 can be turned on to adsorb the bottom end of the adjustment frame 603. At this time, the return spring 607 is compressed and drives the clamping frame 605 and the clamping plate 608 to move upward until the inner side of the clamping plate 608 contacts the outer side of the battery frame. At this time, the outer clamping process of the battery frame can be realized by the external clamping force of multiple clamping plates 608.

[0046] When the outer side of the battery frame needs to be processed, that is, when the inner side needs to be clamped, the battery frame is briefly lifted up and the power of the electromagnet 609 is turned off. Under the action of the reset spring 607, the splint 608 is lowered and the splint 608 is adjusted to the inner side of the battery frame by the micro push rod. The electromagnet 609 is turned on again to move the splint 608 upward, and the main cylinder 3 is turned on to shorten the main cylinder 3, thereby achieving the relative distance between the multiple splints 608, and applying thrust to the inner side of the battery frame through the outer sides of the multiple splints 608 to complete the internal support process.

[0047] By reusing the cooperation between the main cylinder 3 and the linkage assembly 5 as well as the self-clamping assembly 6, the switching between different clamping states is achieved through the left and right displacement and the up and down displacement of the clamping plate 608. Through the action of the main cylinder 3 and the linkage assembly 5, the device can quickly change from the external clamping state to the internal supporting state. The entire switching process can be completed quickly, so that the device can adapt to the punching and welding processing requirements in different positions and improve the processing efficiency.

[0048] like Figure 1 and Figure 4 As shown, the punching and welding assembly 7 includes an adjusting guide rail 701, one side of the adjusting guide rail 701 is adsorbed and connected to the clamping frame 605, a screw rod 704 is movably installed inside the adjusting guide rail 701, the screw rod 704 rotates relative to the adjusting guide rail 701, the outer side surface of the screw rod 704 is threadedly sleeved with a mounting block 702, the mounting block 702 and the adjusting guide rail 701 are movably clamped, a servo motor 703 is fixedly installed on one side of the adjusting guide rail 701, the output end of the servo motor 703 is connected to one end of the screw rod 704, and a puncher 705 and a welding head 706 are symmetrically installed on one side of the mounting block 702.

[0049] The punching and welding component 7 is connected to the self-clamping component 6 by magnetic attraction, and the installation position can be adjusted as needed. The schematic diagram of this application only shows the position diagram of the punching and welding component 7 when the device is in the external clamping state. When the device is in the internal support state, the punching and welding component 7 is installed on the inner side of the self-clamping component 6 by magnetic attraction (not shown in the figure).

[0050] Embodiment: When the external clamping or internal support of the battery frame is completed, the punching and welding assembly 7 is always located on one side of the two self-clamping assemblies 6, and the punching and welding assembly 7 can be selectively installed on the left or right side of the self-clamping assembly 6 as needed, that is, automatic positioning is completed. At this time, by adjusting the height of the adjustment guide rail 701, the welding head 706 and the puncher 705 reach the specified processing position, and the servo motor 703 is turned on to drive the screw rod 704 to rotate, and drive the mounting block 702 to move relative to the adjustment guide rail 701, and the welding head 706 and the puncher 705 are used to perform linear welding and linear punching on the specified position of the battery frame to complete the rapid punching and welding operation.

[0051] By utilizing the adjustment process of multiple self-clamping components 6 and the cooperation between the self-clamping components 6 and the punching and welding components 7, the quick positioning of the punching and welding components 7 is automatically achieved through the adjustment and clamping action of the self-clamping components 6, so that the punching and welding components 7 correspond to the processing position of the battery frame regardless of which side of the self-clamping component 6 they are installed on. At the same time, the punching and welding components 7 can directly provide linear processing, quickly process both sides of the battery frame, and can quickly complete the processing of the four sides of the battery frame by only switching the clamping position, significantly reducing preparation time and improving overall processing efficiency.

[0052] Working principle and usage process:

[0053] Before performing the punching and welding composite processing of the battery frame, the battery can be placed on top of the rack 1, and the battery frame can be kept close to the four corners and directly above the trapezoidal block 601 to complete the preliminary preparation before the composite processing;

[0054] Before starting the composite processing, the main cylinder 3 can be turned on and controlled to extend. At this time, the length of the main cylinder 3 increases, and at the same time, the movable frame 4 at the bottom is driven to move downward. At this time, the distance between the movable frame 4 and the frame 1 increases. At this time, the first fixed seat 501 descends and drives the multiple connecting rods 503 to deflect toward the middle of the movable frame 4. Under the guidance of the guide block 504 and the transverse guide rail 2, the multiple self-clamping components 6 are driven to approach each other until the four corners of the battery frame are fixed by the self-clamping components 6.

[0055] When processing the inner side of the battery frame and clamping the outer side, the micro push rod inside the horizontal slot 602 can be opened to push the adjustment frame 603 to move relative to the trapezoidal block 601 until the inner side of the adjustment frame 603 is against the outer side of the battery frame, and the power of the electromagnet 609 can be turned on to adsorb the bottom end of the adjustment frame 603. At this time, the return spring 607 is compressed and drives the clamping frame 605 and the clamping plate 608 to move upward until the inner side of the clamping plate 608 contacts the outer side of the battery frame. At this time, the outer clamping process of the battery frame can be realized by the external clamping force of multiple clamping plates 608.

[0056] When the outer side of the battery frame needs to be processed, that is, when the inner side is clamped, the battery frame is briefly lifted up and the power supply of the electromagnet 609 is turned off. Under the action of the return spring 607, the clamping plate 608 is lowered and the clamping plate 608 is adjusted to the inner side of the battery frame by the micro push rod. The electromagnet 609 is turned on again to move the clamping plate 608 upward, and the main cylinder 3 is turned on to shorten the main cylinder 3, thereby achieving the relative separation of the multiple clamping plates 608, and applying a thrust to the inner side of the battery frame through the outer sides of the multiple clamping plates 608, and completing the inner support process.

[0057] When the outer clamping or inner support of the battery frame is completed, the punching and welding assembly 7 is always located on one side of the two self-clamping assemblies 6, and the punching and welding assembly 7 can be selectively installed on the left or right side of the self-clamping assembly 6 as needed, that is, automatic positioning is completed. At this time, by adjusting the height of the adjustment guide rail 701, the welding head 706 and the puncher 705 reach the specified processing position, and the servo motor 703 is turned on to drive the screw rod 704 to rotate, and drive the mounting block 702 to move relative to the adjustment guide rail 701, and the welding head 706 and the puncher 705 are used to perform linear welding and linear punching on the specified position of the battery frame to complete the rapid punching and welding operation.

[0058] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
