[0033] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0034] Reference Figure 1This utility model discloses a spot application detection device for solder paste, comprising a processing box 1. First electric slide rails 2 are fixedly connected to the top of both the left and right sides of the processing box 1. First sliding blocks 3 are slidably connected to the outer walls of the first electric slide rails 2, allowing the first sliding blocks 3 to move smoothly left and right on the first electric slide rails 2. A support column 6 is fixedly connected to the top of the first sliding block 3, and a horizontal plate 7 is fixedly connected to the top of the support column 6. A second electric slide rail 11 is fixedly connected to the bottom of the horizontal plate 7. The support column 6 supports the upper horizontal plate 7 and stably positions the horizontal plate 7 at a certain height above the processing box 1. A second sliding block 12 is slidably connected to the outer wall of the second electric slide rail 11, allowing the second sliding block 12 to move back and forth on the second electric slide rail 11. A material cylinder 8 is fixedly connected to the top of the horizontal plate 7. A pump body 10 is fixedly connected to the liquid outlet end of the barrel 8, and a connecting pipe 16 is fixedly connected to the liquid outlet end of the pump body 10. The pump body 10 is the power source for extruding the solder paste in the barrel 8. The connecting pipe 16 is used to transport the extruded solder paste to a designated position for spot application. An electric push rod 15 is fixedly connected to the rear end of the bottom of the connecting plate 13, and the electric push rod 15 is fixedly connected to the outer ring of the connecting pipe 16. The height of the connecting pipe 16 in the vertical direction can be adjusted by the extension and retraction movement of the electric push rod 15, so as to adapt to the spot application needs at different height positions. The bottom of the second sliding block 12 is fixedly connected to the connecting plate 13, and the front end of the bottom of the connecting plate 13 is fixedly connected to the camera 14. The camera 14 is used to capture images of the spot application area in real time during the spot application process, so as to detect and monitor the spot application of the solder paste.

[0035] Reference Figure 2 and Figure 3 A support sleeve 9 is fixedly connected to the top of the material cylinder 8. A first motor 17 is fixedly connected to the top of the support sleeve 9. A drive pulley 18 is fixedly connected to the output end of the first motor 17. Rotating columns 23 are rotatably connected inside both the front and rear ends of the material cylinder 8. A driven pulley 20 is fixedly connected to the top of the rotating column 23. A drive gear 21 is provided at the bottom of the drive pulley 18, and the drive gear 21 is fixedly connected to the output end of the first motor 17. The drive pulley 18 and the driven pulley 20 are connected by a belt 19. When the first motor 17 starts, the driving pulley 18 rotates, which drives the driven pulley 20 to rotate via the belt 19. This causes the rotating column 23 to rotate inside the barrel 8, stirring the solder paste inside the barrel 8. The outer wall of the driving gear 21 is meshed with the driven gear 22, and the driven gear 22 is fixedly connected to the rotating rod 24. The belt 19 is provided between the driving pulley 18 and the driven pulley 20. When the first motor 17 rotates, the driving gear 21 drives the driven gear 22 to rotate, which in turn causes the rotating rod 24 to rotate. The rotating rod 24 and the rotating column 23 work together to further enhance the stirring effect of the solder paste, prevent the solder paste from solidifying, and ensure its good fluidity during the application process.

[0036] Reference Figure 4 and Figure 5 The processing box 1 has fixed blocks 4 fixedly connected to the inner walls of both the front and rear ends. A fan 5 is fixedly connected to one end of each fixed block 4. The fan 5's main function in the device is to ventilate the interior of the processing box 1. During the application of solder paste, some waste gas may be generated, or air circulation may be required to maintain a good working environment. The fan 5 can promptly exhaust the air inside the processing box 1 and introduce fresh air, which helps improve the quality of the working environment and also plays a certain role in ensuring the normal operation of the equipment and the health of the operators. The processing box 1 is equipped with a fixing component, including a second motor 27. The second motor 27 is fixedly connected to the inner wall of the bottom of the processing box 1, and a gear 29 is fixedly connected to the output end of the second motor 27. A fixed plate 25 is fixedly connected to the top of the processing box 1, and a movable table 28 is slidably connected to the inner walls of both the front and rear ends of the fixed plate 25. The movable table 28 has lights on it. The movable table 28 can slide left and right within the fixed plate 25, providing a certain amount of movement space for subsequent clamping of the workpiece. The inner walls of the fixed plate 25 at both ends are provided with sliding grooves 31. A slider 32 is slidably connected to the inner wall of the sliding groove 31. A rack 33 is fixedly connected to one end of the slider 32, and the rack 33 is meshed with the gear 29. A guide block 30 is fixedly connected to the top of the fixed plate 25. A movable block 34 is slidably connected to the outer wall of the guide block 30. A clamping plate 26 is fixedly connected to the top of the movable block 34. A connecting block 35 is fixedly connected to the bottom of the clamping plate 26, and the connecting block 35 is fixedly connected to the rack 33. When the rack 33 moves, the clamping plate 26 moves through the connecting block 35. In the initial state, the clamping plate 26 is in the open state. When it is necessary to fix the workpiece, the workpiece is placed in a suitable position on the fixing plate 25, the second motor 27 is started, the gear 29 rotates and drives the rack 33 to move. The rack 33 drives the clamping plate 26 to move towards the workpiece through the connecting block 35. Multiple clamping plates 26 clamp and fix the workpiece on the fixing plate 25 from different directions, ensuring that the workpiece will not be displaced during the application of solder paste, thereby ensuring the accuracy and quality of the application.

[0037] Working principle: The second motor 27 starts, and the gear 29 at its output end rotates. The rack 33, which meshes with the gear 29, slides in the groove 31 of the fixed plate 25. The rack 29 drives the connecting block 35 to move, and the clamping plate 26 on the connecting block 35 moves accordingly, thereby fixing the workpiece that needs to be spot-applied with solder paste on the fixed plate 25. At the same time, the light on the moving table 28 is turned on, and the first motor 17 is started. The output end of the first motor 17 drives the driving pulley 18 to rotate. The driving pulley 18 drives the driven pulley 20 to rotate through the belt 19, thereby causing the rotating column 23 to rotate. At the same time, it drives the driving gear 21 to rotate, and the driving gear 21 drives the driven gear 22 to rotate. The rotating rod 24 rotates to stir the solder paste in the barrel, preventing it from solidifying. The pump body 10 operates, squeezing the solder paste in the barrel 8 through the connecting pipe 16. The second electric slide rail 11 drives the second sliding block 12 to move, thereby adjusting the position of the connecting plate 13. The electric push rod 15 can adjust the height of the connecting pipe 16, achieving precise control of the solder paste application position. During the solder paste application process, the camera 14 captures images of the application area in real time. Image analysis is used to detect the application quality of the solder paste, such as whether the application amount is accurate and whether the application position is precise. The fan 5 operates to ventilate the inside of the processing box 1, promptly removing waste gas generated during the application process.
