Description

Technical Field

[0001] The utility model relates to the technical field of tin ball spot welding machines, in particular to a CCD laser tin ball soldering machine. Background Art

[0002] At present, with the development of electronic technology and automation technology, tin ball soldering has gradually become an important part of high-precision soldering. Tin balls are mostly used in the processing and production of circuit boards. However, common tin ball soldering is manually operated and controlled. During the fusion process between the flux and the metal manually, it will be uneven, and it is also easy to cause splashing of the metal solution, resulting in personal injuries and product short circuits, affecting the production qualification rate. Traditional tin ball soldering is carried out in a way without vision and is manually operated. Its characteristics are low precision and low difficulty for welding workpieces. If high-precision solder joints are used, this method is not applicable, resulting in low production efficiency and thus losing market competitiveness. Summary of the Utility Model

The middle of the upper end of the substrate is connected with a Y-direction screw rod through a bearing seat. The rear end of the Y-direction screw rod is connected with a Y-direction servo motor through a belt and a synchronous pulley. A limit guide rail is fixedly installed at the upper end of the substrate. The middle of the upper end of the Y-direction sliding seat is connected with an X-direction screw rod through a bearing seat.

The middle of the fixed frame is connected with a Z-direction screw rod through a bearing seat. The upper end of the Z-direction screw rod is connected with a Z-direction servo motor through a coupling. A Z-direction sliding seat is sleeved on the surface of the Z-direction screw rod. A front arm is fixedly installed on the front side of the Z-direction sliding seat. A fixing plate is fixedly installed at the front end of the front arm. A tin ball device is fixedly installed on the left side of the front end of the fixing plate. A second industrial camera is fixedly installed on the right side of the front end of the fixing plate.

A working platform 22 is fixedly installed in the middle of the machine body 1. A first industrial camera 23 is fixedly installed at the bottom end of the machine body 1. Through the first industrial camera 23, the product features can be captured for preliminary positioning. The soldering machine module 2 includes a substrate 3, a Y-direction slide 4 and an X-direction slide 5. The middle of the upper end of the substrate 3 is connected to a Y-direction lead screw 6 through a bearing seat. The rear end of the Y-direction lead screw 6 is connected to a Y-direction servo motor 7 through a belt and a synchronous pulley. A limit guide rail 8 is fixedly installed on the upper end of the substrate 3. The middle of the upper end of the Y-direction slide 4 is connected to an X-direction lead screw 9 through a bearing seat. One end of the X-direction lead screw 9 is connected to an X-direction servo motor 10 through a coupling. A fixed frame 11 is fixedly installed on the upper end of the X-direction slide 5. The middle of the fixed frame 11 is connected to a Z-direction lead screw 12 through a bearing seat. The upper end of the Z-direction lead screw 12 is connected to a Z-direction servo motor 13 through a coupling. A Z-direction slide 14 is sleeved on the surface of the Z-direction lead screw 12. A front arm 15 is fixedly installed on the front side of the Z-direction slide 14. A fixing plate 16 is fixedly installed at the front end of the front arm 15. A solder ball device 17 is fixedly installed on the left side of the front end of the fixing plate 16. A second industrial camera 18 is fixedly installed on the right side of the front end of the fixing plate 16. A foot cup 19 is fixedly installed at the lower end of the machine body 1. The foot cup 19 is located at the lower end of the machine body 1, which can effectively provide balance for the soldering machine. A Y-direction slide 4 is sleeved on the surface of the Y-direction lead screw 6. The lower end of the Y-direction slide 4 is slidably connected to the limit guide rail 8 through a slider. The Y-direction slide 4 slides on the surface of the Y-direction lead screw 6. The limit guide rail 8 on the surface of the Y-direction lead screw 6 can limit the Y-direction slide 4, making the Y-direction slide 4 more stable when moving. The Z-direction servo motor 13 is fixedly installed on the upper end of the fixed frame 11.

The soldering machine can perform high-precision welding, which can improve the product qualification rate and effectively save production time and labor costs.

[0020] Working principle: When in use, place the product randomly on the working platform 22. The first industrial camera 23 captures the product features for preliminary positioning. At this time, the second industrial camera 18 will locate above the product for secondary capture and then precise positioning. After system analysis, the solder joint position is confirmed. Subsequently, the control platform sends signals to the X-axis slide 5, Y-axis slide 4, and Z-axis slide 14. After receiving the instructions, the X-axis servo motor 10, Y-axis servo motor 7, and Z-axis servo motor 13 start to operate, driving the X-axis slide, Y-axis slide 4, and Z-axis slide 14 to move to the specified positions. At this time, the solder ball device 17 has been positioned above the solder ball. Subsequently, the laser in the solder ball device 17 starts to emit light to melt the solder ball, and then a small amount of nitrogen is used to spray the melted solder ball onto the solder pad to complete the soldering. Workers only need to randomly place the product into the working platform 22 and press the start switch to complete the above soldering actions. The equipment has strong versatility and can, according to the needs of product characteristics, cooperate with the CCD positioning system to meet the requirements of large-scale production on the assembly line.
