[0002] After high-frequency brazing, there will be excess flux or welding slag on the surface of the harmonica tube. If it is not cleaned, particles will form. When the particles rub against the battery, it is easy to damage the insulation layer on the surface of the battery, and it will also accelerate the aging and damage of the harmonica tube. At present, the cleaning of harmonica tubes on the market is mainly done by manual cleaning. Since most harmonica tubes are made of 3003 aluminum, the material is relatively soft, and there are openings at the ends. When cleaning, it is necessary to plug the openings at the ends with additional plugs, and then rely on manual grinding or chemicals to clean solder joints, solder spots, etc. Not only does it require a large investment in manpower and material resources, but it is also inefficient and cannot meet the high-efficiency requirements of large-scale cleaning. At the same time, the use of chemicals during cleaning also has a certain impact on operators and the environment. Summary of the invention

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following Figure 1-Figure 8 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] The present invention proposes an intelligent laser cleaning device, including a device frame, a transmission line for transmitting products is provided through the lower part of the device frame, a conveying assembly 1 is provided on the transmission line, and the conveying assembly 1 is usually provided with a plurality of conveying assemblies 1, and the laser cleaning of the product is performed by entering the device from the device inlet end on the transmission line in the form of an assembly line, and the cleaned product is outputted from the transmission line through the device outlet end. The following is a further explanation using the harmonica pipe as an example.

[0025] The device is provided with a gripping and rotating assembly 2 for gripping the product and assisting the product to rotate during the cleaning process, and the gripping and rotating assembly 2 is placed on both sides of the transmission line. A laser cleaning assembly 3 is arranged above the gripping and rotating assembly 2.

[0026] When the conveying component is transported to the position of the gripping rotating component 2 , the gripping rotating component will grip the product to be cleaned and separate it from the conveying component, and then the laser cleaning component 3 will clean the product.

[0027] In this embodiment, the conveying assembly includes a bottom plate 11 mounted on the transmission line through a slider, and a lifting plate 15 is connected to the bottom plate 11 through a lifting mechanism; the lifting mechanism includes a lifting cylinder 13 arranged on the bottom plate 11, and the ends between the lifting plate 15 and the bottom plate 11 are connected through a guide shaft 12 to maintain stability during movement. Since the harmonica tube material is relatively soft, in order to make the product more stable and not shake during the up and down movement of the lifting plate 15, a vacuum suction cup 14 for adsorbing the product is provided on the lifting plate 15. The vacuum suction cup 14 is placed at the bottom of the lifting plate 15 through a connecting block, and a sensor 141 is also provided on the connecting block to sense the presence or absence of the product. The number of the vacuum suction cups 14 is set according to the number of products. The product in the present invention is a conveying unit with a tray 16, and the tray 16 is placed on the lifting plate 15 for conveying. The tray 16 is provided with a suction cup through hole, and a stopper 17 for spacing the product is also provided on the tray. When the lifting cylinder 13 works, the whole pallet is lifted. The length of the harmonica pipe is longer, and the two ends will extend out of the two ends of the pallet, and the end extending out is also convenient for clamping the rotating assembly.

[0028] The clamping rotating assembly 2 includes a fixed vertical plate 2 vertically arranged outside the transmission line, and a clamping claw cylinder 24 arranged on one side of the fixed vertical plate 2. The clamping claw head 241 of the clamping claw cylinder 24 cooperates with the lower open end of the harmonica tube, that is, when the clamping claw cylinder 24 is clamping, its clamping claw head 241 will block the open end of the harmonica tube, thereby preventing dust or other impurities from entering the tube during cleaning. Since a cylindrical port 41 is arranged at the end of the harmonica tube, and the cylindrical port 41 is in a vertical state with the main body of the harmonica tube, in order to ensure stability and prevent sliding during clamping, a guide plate 242 is arranged inside the clamping cylinder 24, and the guide plate 242 is arranged in a V-shaped opening. The opening of the guide plate 242 blocks the cylindrical part of the port to the left and right to guide the harmonica tube so that the clamping claw head 241 can effectively block the open end of the harmonica tube.

[0029] The gripper cylinder 24 is rotated by a rotating mechanism placed on the other side of the fixed vertical plate 21. The number of the gripper cylinders 24 is equal to the number of products. The rotating mechanism includes a servo motor 22 and a synchronous pulley 23 connected to the servo motor 22 through a synchronous belt. The synchronous pulley 23 is connected to the gripper tooling. The servo motor 22 drives the gripper tooling to rotate.

[0030] The fixed vertical plate 21 is provided with a cleaning assembly, which includes a laser cleaning machine 31 and a dust suction port 32 provided at the head of the laser cleaning machine 31; one end of the dust suction port 32 is connected to a dust suction mechanism, which is used to timely absorb the debris generated by the laser cleaning machine 31 during cleaning. A Z-axis module for adjusting the focal length of the laser cleaning machine is connected to one side of the laser cleaning machine 31, and more than two laser cleaning machines are arranged in parallel. The harmonica pipe enters the lower part of the clamping and rotating assembly through the conveying assembly, is clamped and rotated by the clamping and rotating assembly, and is transported out of the equipment by the transmission line after being cleaned by the laser cleaning assembly.

[0031] The clamping rotating assembly is provided with two groups, which are respectively placed on both sides of the transmission line. A group of synchronous connecting rod assemblies are provided at the bottom of the clamping rotating assembly to realize the synchronous reciprocating motion between the two groups of clamping rotating assemblies. Specifically, the two ends of the bottom of the fixed bracket 21 are placed on a group of guide rails through sliders. The connecting rod assembly includes a screw rod 25 placed at the bottom of the fixed bracket and a compatible synchronous pulley arranged at the end of the screw rod. A synchronous connecting rod is provided on one side of the compatible synchronous pulley. The synchronous connecting rod is respectively connected to the fixed brackets on both sides, that is, when the compatible synchronous pulley is driven by a motor, the motor works and drives the fixed bracket to reciprocate synchronously on the screw rod. The fixed brackets on both sides of the present invention adopt synchronous action to realize the distance adjustment between the two, so as to adapt to harmonica pipes of different lengths. The device can adopt a closed structure, that is, the above-mentioned mechanisms are all arranged on a closed door panel for enclosure, so as to prevent the removed dust from spreading or polluting the environment.

[0032] In order to better understand the principle of the device of the present invention, the cleaning method of any of the above-mentioned harmonica tube laser cleaning devices comprises the following steps: S1, placing the harmonica tube to be cleaned on the tray 16 on the conveying assembly and entering the equipment through the conveying line; S2, when the conveying assembly reaches the position of clamping the rotating assembly, the pallet 16 is lifted up by the lifting mechanism of the conveying assembly; S3, the clamping rotating assembly clamps the product on the pallet, and the lifting mechanism resets; when clamping, the guide plate 242 will first guide the product, which is conducive to the clamping cylinder to clamp the product port. This action not only clamps the product, but also seals the product port, killing two birds with one stone.

[0033] S4, the laser cleaning component will clean the product on the clamping rotating component, and timely absorb the impurities after cleaning through the dust suction port 32; when one surface of the harmonica tube is cleaned, the clamping rotating component rotates, driving the product to rotate, so as to assist the product to complete laser cleaning at different positions at different angles; S5. After cleaning is completed, the lifting mechanism is lifted again, and the clamping rotating assembly releases the cleaned product onto the tray 16, and finally the conveyor line conveys the cleaned product out of the equipment. There are multiple groups of products on the conveyor line to realize the work of the assembly line, which greatly improves the cleaning efficiency.
