Description

A post-laser welding inspection device for explosion-proof valves Technical Field

[0001] This invention relates to the field of laser processing quality inspection technology, specifically to a post-laser welding inspection device for explosion-proof valves. Background Technology

[0002] In the manufacturing process of new energy power batteries, the explosion-proof valve, as a core component for battery safety protection, directly determines whether the battery can accurately depressurize and avoid explosion under thermal runaway conditions through its laser welding quality. However, existing explosion-proof valve laser welding post-inspection devices generally adopt a step-by-step inspection process. This involves an initial inspection to assess the overall weld quality, followed by shaping of the explosion-proof valve, and then a second inspection to complete the final overall inspection. This process may present several problems. During the initial inspection, the welding process may cause the explosion-proof valve to shift position, affecting the accuracy and consistency of the initial inspection results. Furthermore, in the subsequent shaping process, the shaping device uses a rigid extrusion method, which cannot adaptively adjust to the actual deformation state of the explosion-proof valve. This can easily lead to stress concentration at the welding position and even secondary damage such as weld area voids, severely reducing product yield and the safety of the welded structure.

[0003] To address the aforementioned issues, we propose a post-laser welding inspection device for explosion-proof valves. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a post-laser welding inspection device for explosion-proof valves. By utilizing a combination of pre-leveling and adaptive shaping, it can more accurately identify welding defects in subsequent inspections while ensuring that the weld structure is not damaged. This prevents defective products from flowing into downstream processes from the source and significantly improves the quality of inspection.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a post-laser welding inspection device for explosion-proof valves, comprising a support base, a valve body conveyor disposed on one side of the top of the support base, a laser welding machine disposed on the top of the support base on one side of the valve body conveyor, and an inspection component disposed on the top of the support base on the right side of the laser welding machine. A first robotic arm is disposed on the top of the support base on the right side of the valve body conveyor, a rotating component is disposed on the top of the support base on the right side of the rear side of the valve body conveyor, and a shaping component, a shaping inspection instrument, and a second robotic arm are disposed on the periphery of the rotating component on the top of the support base. The component includes a first electric slide rail fixedly installed on one side of the top of the support base, and a fixing frame fixedly installed on the output part of the first electric slide rail. The surface of the fixing frame is fixedly installed on the camera detector. A reset component is provided on the top of the support base between the camera detector and the laser welding machine. The shaping component includes two support platforms fixedly installed on the top of the support base. Lifting telescopic rods are embedded and fixedly installed in the top of the two support platforms. A shaping pressure plate is fixedly installed at the output ends of the two lifting telescopic rods. Support top columns are fixedly installed on the lower sides of the two opposite sides of the two support platforms. A pressing component is provided at the bottom of the shaping pressure plate.

[0006] Furthermore, a reinforcing plate is fixedly connected to the surface of the support base on one side of the valve body conveyor, and the top of the reinforcing plate is fixedly connected to the bottom of the valve body conveyor.

[0007] Furthermore, the camera inspection instrument is installed directly above the valve body conveyor, and its detection field covers the explosion-proof valve on the valve body conveyor after laser welding, and is used to collect image information of the weld area to realize online detection of welding quality.

[0008] Furthermore, the reset assembly includes a positioning frame fixedly installed on the top of the support base. A positioning inclined plate is fixedly installed at the bottom of the positioning frame, and a moving groove is opened at the bottom of the positioning inclined plate. Adjusting screws are threaded to opposite sides of the top of the inner wall of the moving groove. A leveling roller is rotatably installed at the bottom of the two adjusting screws. A reference plate is set on the top of the leveling roller on one side of the adjusting screw. Reference lines are laser-engraved on the surface of the reference plate to ensure the level of the leveling roller.

[0009] Furthermore, the rotating assembly includes a stepper motor fixedly mounted on the top of the support base. A placement plate is fixedly mounted on the output end of the stepper motor. The placement plate is a disc structure composed of four explosion-proof valve placement platforms, used to achieve intermittent clockwise rotation of ° each time under the drive of the stepper motor. The valve body conveyor, shaping assembly, second robot, shaping inspection instrument, and first robot are arranged clockwise along the circumference of the rotating assembly. The second robot and the shaping inspection instrument are arranged in the same horizontal position. The remaining adjacent positions, i.e., between the valve body conveyor and the shaping assembly, between the shaping assembly and the second robot, and between the first robot and the valve body conveyor, are all distributed at ° angles. The stepper motor drives the placement plate to rotate ° clockwise each time, causing the explosion-proof valves on the placement plate to sequentially align with the positions corresponding to the first robot, the valve body conveyor, the shaping assembly, the second robot, and the shaping inspection instrument, and finally, the second robot grips and unloads the valves.

[0010] Furthermore, the supporting top column is located below the rotating assembly, and the placement plate is located above the supporting top column. The supporting top column is provided with an ejector block, which is configured to be able to lift upward. When the shaping pressure plate moves downward, the ejector block pushes upward to support the explosion-proof valve on the placement plate from below, thereby improving the support stability and shaping quality during the shaping process.

[0011] Furthermore, both the first robotic arm and the second robotic arm include a moving track and an explosion-proof valve gripper. The explosion-proof valve gripper is mounted on the moving track and can move back and forth along the moving track to grip and transport the explosion-proof valve to a predetermined work position.

[0012] Furthermore, the extrusion assembly includes a conversion shell fixedly installed at the bottom of the forming plate. Two extrusion shells are fixedly installed above and below the placement plate at the bottom of the conversion shell. A connecting pipe is fixedly installed between the conversion shell and the extrusion shells. A plurality of telescopic piston cylinders are fixedly installed on the lower side of the inner wall of the extrusion shell, and telescopic piston blocks are movably installed on the inner walls of the telescopic piston cylinders. Telescopic rods are fixedly installed at the bottom of the telescopic piston blocks. Reset piston cylinders are embedded in both the left and right sides of the inner wall of the conversion shell, and reset piston blocks are movably installed on the inner walls of the reset piston cylinders. A damping spring is fixedly installed on one side of the surface of the reset piston block, and the fixed end of the damping spring is fixedly connected to the inner wall of the reset piston cylinder.

[0013] Furthermore, a starting pusher is slidably embedded on the bottom of the conversion housing near the damping spring. The starting pusher can slide vertically, and a connecting block is fixedly installed on the top of the starting pusher. The bottom of the connecting block extends through into the interior of the conversion housing, and the top of the connecting block is in contact with the inner wall of the conversion housing. The interior of the conversion housing is pre-filled with hydraulic oil. When the starting pusher is squeezed and moves upward, it drives the connecting block to move synchronously, closing the oil passage between the connecting block and the inner wall of the conversion housing, thereby blocking the flow of hydraulic oil. At this time, the positions of several telescopic rods are locked to achieve stable support during the shaping process and ensure the shaping quality.

[0014] Furthermore, the two extrusion shells are located above the placement plate, and the extrusion shells can just extrude and shape the explosion-proof valve on the placement plate during the pressing process of the shaping plate. The connecting pipe can ensure the connection between the conversion shell and the extrusion shell, and the lower ends of several telescopic rods extend through to the bottom of the extrusion shell.

[0015] Compared with the prior art, the present invention provides a post-laser welding inspection device for explosion-proof valves, which has the following beneficial effects: 1. By setting a flat structure before the initial inspection, the device can perform position correction and surface flattening of the explosion-proof valve after welding and before inspection, effectively eliminating the positional offset or local warping of the explosion-proof valve caused by the welding process, ensuring the consistency of the inspection reference surface, thereby significantly improving the accuracy of the initial inspection and reducing the risk of false detection and missed detection caused by changes in workpiece posture.

[0016] 2. The device adopts an adaptive shaping structure, which can adjust the shaping position in real time according to the actual deformation state of the explosion-proof valve after welding. This avoids the secondary damage caused by excessive extrusion or uneven force in the welding area caused by traditional rigid shaping devices, which can lead to problems such as weld hole and micro-crack, thus ensuring the integrity of the weld structure and the reliability of the seal.

[0017] 3. This device integrates the detection function and the adaptive shaping function at the same workstation, enabling precise adjustments to the shaping process while avoiding errors in the workpiece detection process, increasing the accuracy of detection, and effectively improving the overall detection quality and product yield.

[0018] 4. This device utilizes a combination of pre-leveling and adaptive shaping to enable subsequent inspections to more accurately identify welding defects while ensuring that the weld structure is not damaged. This prevents defective products from flowing into downstream processes and significantly improves the quality of inspection. Attached Figure Description

The rotation assembly 7 includes a rotating assembly fixedly installed on the top of the support base 1. A stepper motor 701 is provided, and a placement plate 702 is fixedly installed at the output end of the stepper motor 701.

The other adjacent positions, namely between the valve body conveyor 2 and the shaping component 8, between the shaping component 8 and the second robot arm 9, and between the first robot arm 6 and the valve body conveyor 2, are all distributed at a 90° angle.Stepper motor 701 drives placement tray 702 to rotate 90° clockwise each time, so that the explosion-proof valve on placement tray 702 is sequentially aligned with the corresponding workstations of first robotic arm 6, valve body conveyor 2, shaping component 8, second robotic arm 9, and shaping inspection instrument 11, and finally the second robotic arm 9 picks up the material; the shaping component 8 includes two support platforms 801 fixedly installed on the top of support base 1, and lifting telescopic rods 802 are embedded and fixedly installed in the top of the two support platforms 801.

Supporting top columns 804 are fixedly installed on the lower sides of two opposite sides; the supporting top columns 804 are located below the rotating assembly 7, and the placement plate 702 is located above the supporting top columns 804. An ejector block 8041 is provided inside the supporting top columns 804. The ejector block 8041 is configured to be able to lift upward. When the shaping pressure plate 803 moves downward, the ejector block 8041 pushes upward to support the explosion-proof valve on the placement plate 702 from below, thereby improving the support stability and shaping quality during the shaping process; both the first robotic arm 6 and the second robotic arm 9 include a moving track 601 and an explosion-proof valve gripper. 602, the explosion-proof valve gripper 602 is installed on the moving rail 601 and can reciprocate along the moving rail 601 to grip and transport the explosion-proof valve to the predetermined work position; the bottom of the forming plate 803 is provided with an extrusion assembly 10, the extrusion assembly 10 includes a conversion shell 1001 fixedly installed at the bottom of the forming plate 803, the bottom of the conversion shell 1001 is located above and below the placement plate 702 with two extrusion shells 1002 fixedly installed, a connecting pipe 1003 is fixedly installed between the conversion shell 1001 and the extrusion shells 1002, and a number of extrusion shells 1002 are fixedly installed on the lower side of the inner wall of the extrusion shell 1002. Telescopic piston cylinder 1004, telescopic piston blocks 1005 are movably installed on the inner wall of several telescopic piston cylinders 1004, and telescopic rods 1006 are fixedly installed at the bottom of several telescopic piston blocks 1005. Two extrusion shells 1002 are located above the placement plate 702, and the extrusion shells 1002 can just extrude and shape the explosion-proof valve on the placement plate 702 during the process of the shaping plate 803 pressing down. The connecting pipe 1003 can ensure the connection between the conversion shell 1001 and the extrusion shell 1002.

A connecting port block 1 is fixedly installed on the top of the starting pusher 1010. 011, the bottom of the connecting block 1011 extends through to the interior of the conversion shell 1001, and the top of the connecting block 1011 fits against the inner wall of the conversion shell 1001; the interior of the conversion shell 1001 is pre-filled with hydraulic oil. When the starting pusher 1010 is compressed and moves upward, it drives the connecting block 1011 to move synchronously, closing the oil passage between the connecting block 1011 and the inner wall of the conversion shell 1001, thereby blocking the flow of hydraulic oil. At this time, the positions of several telescopic rods 1006 are locked to achieve stable support during the shaping process and ensure the shaping quality.

[0023] The working process of the explosion-proof valve laser welding post-inspection device in this embodiment is as follows: The explosion-proof valve to be welded is conveyed by the valve body conveyor 2 to the laser welding machine 3 station. The laser welding machine 3 performs laser welding on the explosion-proof valve. After welding, the explosion-proof valve continues to be conveyed forward with the valve body conveyor 2. When the explosion-proof valve moves to below the reset assembly 5, the leveling roller 504 contacts the surface of the explosion-proof valve. Since the height of the leveling roller 504 can be adjusted by adjusting the screw 503 and the levelness is ensured by the reference line on the reference plate 505, the leveling roller 504 applies slight pressure to the explosion-proof valve during its movement to pre-level and correct any possible positional displacement or local warping of the explosion-proof valve during the welding process. This step ensures that the surface reference of the explosion-proof valve is consistent. To provide a stable inspection surface for subsequent inspections; after being leveled, the explosion-proof valve continues to move to the area below the camera inspection instrument 403. The camera inspection instrument 403 collects image information of the weld area and identifies appearance defects such as broken welds, pores, weld deviations, and weld slag through its built-in visual algorithm, completing the first inspection. The inspection by the camera inspection instrument 403 does not require subsequent reshaping operations, and the data after inspection by the camera inspection instrument 403 can be saved and reserved. This function is a mature function of the camera inspection instrument 403, and will not be elaborated on in this application. The explosion-proof valve gripper 602 of the first robotic arm 6 moves along the moving track 601 to the end of the valve body conveyor 2, grips the conveyed explosion-proof valve, and transfers it to the placement plate 702 of the rotating component 7. On a placement platform, a stepper motor 701 drives a placement plate 702 to rotate 90° clockwise, delivering the explosion-proof valve to the corresponding station of the forming component 8. When the placement plate 702 delivers the explosion-proof valve to the station of the forming component 8, the ejector block 8041 inside the support column 804 rises upward, supporting the bottom of the explosion-proof valve from below, forming a stable forming support base. Subsequently, the lifting telescopic rod 802 drives the forming pressure plate 803 to move downward, and the extrusion shell 1002 descends with the forming pressure plate 803. The telescopic rod 1006 at its bottom first contacts the upper surface of the explosion-proof valve. Since the explosion-proof valve may have varying degrees of deformation or warping after welding, each telescopic rod 1006 will produce different degrees of deformation when contacting the surface of the explosion-proof valve according to the actual surface contour. The upward retraction of the piston causes the telescopic piston block 1005 to move upward within the telescopic piston cylinder 1004, squeezing the hydraulic oil through the connecting pipe 1003 into the interior of the conversion housing 1001. As the shaping pressure plate 803 continues to press down, the bottom of the starting pusher 1010 contacts the upper surface of the placement plate 702 or the support top column 804 and is subjected to upward squeezing force, causing the starting pusher 1010 and the connecting port block 1011 to move upward synchronously. When the connecting port block 1011 moves to be completely in contact with the inner wall of the conversion housing 1001, the oil passage is closed and the flow of hydraulic oil is blocked. At this time, the position of the telescopic rod 1006 is locked, that is, the array of telescopic rods 1006 forms a contoured contact surface that perfectly matches the surface morphology of the explosion-proof valve.The shaping plate 803 continues to press down to the set position, and the array of telescopic rods 1006 applies uniform and close pressure to the explosion-proof valve in a locked posture, completing the adaptive shaping of the explosion-proof valve. Since the telescopic rods 1006 are positioned according to the actual shape of the explosion-proof valve, the shaping pressure can be evenly distributed, avoiding secondary damage to the weld area caused by uneven force in traditional rigid shaping devices. After shaping, the lifting telescopic rods 802 drive the shaping plate 803 to rise, start the pusher 1010 to disengage from the pressure, the damping spring 1009 pushes the reset piston block 1008 to reset, the connecting port block 1011 descends, the oil circuit is restored, and the telescopic rods 1006 automatically reset under the action of hydraulic oil return, waiting for the next shaping. The stepper motor 701 drives the placement plate 702 to rotate 90° again, sending the shaped explosion-proof valve to the composite station corresponding to the second robot 9 and the shaping inspection instrument 11. The shaping inspection instrument 11 performs a second quality inspection on the shaped explosion-proof valve. The explosion-proof valve gripper 602 of component 9 picks up the qualified explosion-proof valve and transfers it to the unloading area, completing the entire processing flow. Thus, a complete cycle of welding, inspection, shaping, re-inspection, and unloading is completed. This application, by setting up the reset component 5, pre-flattens the explosion-proof valve before the initial inspection, effectively eliminating positional offsets and local warping caused by the welding process, ensuring the consistency of the inspection reference surface, and significantly improving the accuracy of the initial inspection. By setting up the telescopic rod array and hydraulic locking mechanism in the extrusion component 10, adaptive distribution of shaping pressure is achieved, enabling flexible shaping according to the actual deformation state of the explosion-proof valve, avoiding secondary damage to the weld area caused by rigid shaping, and ensuring the integrity and sealing reliability of the weld structure. Through the workstation layout of the rotating component 7, the first robotic arm 6, the second robotic arm 9, and the shaping and inspection instrument 11, a streamlined operation of welding, inspection, shaping, re-inspection, and unloading is realized, improving production efficiency and automation level.
