[0038] Today, with the increasing integration of electronic products, the traditional soldering process with soldering iron has become increasingly unsuitable, and laser soldering as a new process has emerged as the times require. Laser soldering of soldering balls is the most difficult and efficient new process in the field of laser soldering.

[0039] At present, the existing welding equipment needs to adjust the tin spraying distance of the tin spraying ball in advance when processing different products, and the tin spraying distance needs to be adjusted again when welding another product. Even for different welding positions of the same product, the tin spraying distance needs to be adjusted again after welding one position, and then the other position is welded, which greatly affects the welding efficiency.

[0040] Based on the above ideas and problems, the present application provides a tin spraying ball welding equipment. It can be understood that the tin spraying ball welding equipment can automatically adjust the welding distance when welding different welding points with different optimal welding distances.

[0041] Please refer to Figures 1 to 4 The present application provides a tin spraying ball welding equipment 100, which includes a base 1, a driving mechanism 2 and a welding mechanism 3. The base 1 is provided with a processing position 12 for placing a workpiece. The driving mechanism 2 is arranged on the base 1 and is provided with a connecting plate 21. The welding mechanism 3 includes a distance measuring module 31 and a welding device 32, both of which are arranged on the connecting plate 21. The distance measuring module 31 is electrically connected to the welding device 32 and is used to detect the distance between the welding device 32 and the processing position 12. The welding device 32 is provided with a nozzle 3224. The driving mechanism 2 drives the welding device 32 to approach or move away from the processing position 12, so that the nozzle 3224 can spray tin on the product in the processing position 12 for welding.

[0042] In this embodiment, as Figures 1 to 4As shown, the base 1 is used to install the driving structure and the welding mechanism 3, and is provided with a control system capable of controlling the driving mechanism 2 and the welding mechanism 3, and the user can control the operation and stop of the soldering ball welding equipment 100 through the buttons on the base 1. When the product is transported to the to-be-processed position 12, the driving mechanism 2 drives the welding mechanism 3 to move to the to-be-processed position 12. After the welding mechanism 3 is aligned with the product at the to-be-processed position 12, the ranging module 31 detects the distance between the to-be-welded point of the to-be-processed product and the welding device 32, and transmits the detected distance to an external host computer. The host computer controls the welding device 32 to adjust the distance from the to-be-welded point until the distance between the nozzle 3224 of the welding device 32 and the to-be-welded point reaches the preset optimal welding distance. At this time, the driving mechanism 2 stops working, and the welding mechanism 3 starts welding. The soldering ball welding equipment 100 first detects the distance between the welding device 32 and the to-be-welded product through the ranging module 31, and then adjusts the distance by using the driving mechanism 2. In this way, when the soldering ball welding equipment 100 welds multiple different welding points of the same product, the welding distance can be automatically adjusted according to the different optimal welding distances of different welding points, and the welding of the product is completed in a single welding process without the need to repeatedly start and stop the soldering ball welding equipment 100 to adjust the welding distance of the welding device 32 and weld different welding points of the same product, thereby greatly improving the welding efficiency of the soldering ball welding equipment 100. At the same time, when facing different to-be-welded products, the soldering ball welding equipment 100 also does not need to repeatedly start and stop to adjust the distance between the welding device 32 and the product, but automatically adjusts the welding distance through the ranging device and the preset optimal welding distance, thereby saving production time and reducing the workload of the user.

[0043] In actual implementation, the base 1 is connected with a control host computer, the control host computer is electrically connected with the driving mechanism 2 and the welding mechanism 3, can detect the working conditions of the driving mechanism 2 and the welding mechanism 3 in real time, and record the welding results of the welding mechanism 3 on the product. Before welding, the operation of the driving mechanism 2 and the welding mechanism 3 can be pre-set through the control host computer, so that the preset optimal welding distance value is input to the driving mechanism 2 and the welding mechanism 3, so that the driving mechanism 2 can adjust the distance between the welding mechanism 3 and the to-be-welded point according to the preset welding distance during the working process, thereby achieving the best welding effect.

[0044] In an embodiment, the ranging module 31 comprises a ranging instrument mounting plate 311 and a ranging instrument main body 312.

At the same time, the distance measuring instrument body 312 is connected to the distance measuring instrument mounting plate 311 through the mounting portion 3111, so that the distance measuring instrument body 312 is convenient to disassemble and assemble. The distance measuring instrument mounting plate 311 is also provided with an avoiding space 3112 to further reduce the distance between the distance measuring instrument body 312 and the nozzle 3224 of the welding device 32, improve the distance measuring accuracy of the distance measuring instrument body 312 to the welding device 32 and the product to be welded, and ensure the welding quality.

When the distance measuring instrument body 312 and the welding device 32 are installed, whether the distance measuring instrument body 312 and the welding device 32 are installed in place can be judged through the pressure sensor 313. If the detected value of the pressure sensor 313 is too small, the installation screw of the distance measuring instrument body 312 and the welding device 32 can be tightened. If the detected value of the pressure sensor 313 is too large, the installation screw of the distance measuring instrument body 312 and the welding device 32 can be loosened, so that the distance measuring instrument body 312 and the welding device 32 are installed in place. At the same time, the pressure sensor 313 can detect whether the distance measuring instrument body 312 and the welding device 32 are loose during use, so that the user can adjust the distance measuring instrument body 312 and the welding device 32 in time to avoid affecting the normal work.

[0049] In actual implementation, the pressure sensor 313 is arranged on the connecting plate 21 and electrically connected to the external host computer. The pressure between the distance measuring instrument body 312 and the welding device 32 can be displayed to the external host computer in real time.
