The product 6 has an end 61. The cleaning device 2 includes a cleaning tank 21. The lifting device 3 is used to move the cleaning tank 21 and the fixing clamps 11 relative to each other along the height direction Z of the aluminum material welding end cleaning equipment, so that the end 61 enters or exits the cleaning tank 21. The control device is used to control the start and stop of the lifting device 3 and the conveying device 1.

[0020] From the above description, the beneficial effects of the present application are as follows: The present application provides an aluminum material welding end cleaning equipment. Only the end 61 of the product 6 enters the cleaning tank 21 for cleaning. The size of the cleaning tank 21 only needs to adapt to the end 61, and does not need to adapt to the whole product 6. Therefore, the size of the cleaning tank 21 can be greatly reduced, that is, the amount of chemical agent and clean water used can be significantly reduced.

[0021] In some embodiments, please refer to Figure 2The lifting device 3 is connected with the cleaning tank 21 and is used to move the cleaning tank 21 up and down along the height direction Z of the aluminum welding end cleaning equipment, and switches between the high position and the low position. When the cleaning tank 21 is at the high position, the end 61 is located in the cleaning tank 21. When the cleaning tank 21 is at the low position, the end 61 is located outside the cleaning tank 21.

[0022] From the above description, it can be known that, compared with moving the conveying device 1 or the fixed clamp 11, the implementation is simpler to move the cleaning tank 21, and the lifting device 3 is arranged below the cleaning tank 21.

[0023] In some embodiments, the lifting device 3 includes a cylinder 31 and a guide column 32. The guide column 32 is fixed to the lower side of the cleaning tank 21. The conveying device 1 is provided with a mounting plate. The cylinder 31 is fixed to the mounting plate. The mounting plate is provided with a guide sleeve corresponding to the guide column 32.

[0024] From the above description, it can be known that, through the cooperation of the guide column 32 and the guide sleeve, the movement of the cleaning tank 21 is more stable.

[0025] In some embodiments, please refer to Figure 1 The number of the cleaning devices 2 is two. The two cleaning devices 2 are respectively located on the two sides of the conveying device 1 along the width direction Y of the aluminum welding end cleaning equipment. The product 6 has two ends 61 that need to be cleaned. The two cleaning devices 2 are respectively used to clean the two ends 61 of the product 6.

[0026] From the above description, it can be known that, by arranging one cleaning device 2 on each side of the conveying device 1, the demand that both ends 61 of the product 6 need to be cleaned can be met.

[0027] In some embodiments, the fixed clamp 11 includes a fixed plate and a plurality of hooks 111. In the width direction Y of the aluminum welding end cleaning equipment, the plurality of hooks 111 are distributed in mirror symmetry about the center line of the fixed plate.

[0028] From the above description, it can be known that, by arranging the hooks 111 in mirror symmetry, the first product 6, such as the aluminum material used on the left door of the car, can be placed on the fixed clamp 11, and the second product 6, which is mirror symmetric to the first product 6, such as the aluminum material used on the right door of the car, can also be placed on the fixed clamp 11.
