[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3This utility model provides an embodiment of an automatic solder paste supply device, including a mounting frame 1. The mounting frame 1 serves as the basic support structure for the entire automatic solder paste supply device, providing a position for the installation and fixing of other components. A first mounting plate 2 is fixedly connected to the rear side of the inner wall of the mounting frame 1. The first mounting plate 2 provides a stable mounting platform for a solder storage tank 3, enabling the solder storage tank 3 to be firmly installed on the device. The solder storage tank 3 is fixedly connected to the top of the first mounting plate 2. The solder storage tank 3 is used to store solder paste and serves as a storage container for solder paste, providing a source of solder paste for subsequent supply operations. An extrusion assembly is provided inside the solder storage tank 3 to extrude the solder paste from the solder storage tank 3, thereby achieving the desired solder paste supply. The first mounting plate 2 has a drive assembly on its inner wall. The drive assembly provides power to the extrusion assembly, which drives the extrusion assembly to work, thereby realizing the automatic extrusion of solder paste. The second mounting plate 12 is fixedly connected to the front side of the inner wall of the mounting frame 1. The second mounting plate 12 is used to install the filter 13 and ensure the stable installation of the filter 13. The filter 13 is fixedly connected to the bottom of the second mounting plate 12. The filter 13 can filter the extruded solder paste. The output end of the filter 13 is fixedly connected to the discharge pipe 14. The discharge pipe 14 is used to transport the filtered solder paste to the position where it is needed. The front side of the mounting frame 1 is fixedly connected to the fixing assembly, which is used to fix the discharge pipe 14.

[0032] Reference Figures 1-3 The extrusion assembly includes a piston 4, whose outer wall is slidably connected to the inside of the solder storage tank 3. When the piston 4 moves downward in the solder storage tank 3, it can exert pressure on the solder paste and extrude the solder paste. A connecting rod 5 is fixedly connected to the top of the piston 4. The connecting rod 5 connects the piston 4 and the connecting plate 10 and plays the role of transmitting power. The connecting plate 10 is fixedly connected to the top of the connecting rod 5. The connecting plate 10 connects the connecting rod 5 and the rack plate 9 together, so that the connecting rod 5 can move up and down with the rack plate 9. The rack plate 9 is fixedly connected to the bottom of the end of the connecting plate 10 away from the connecting rod 5. Under the action of the drive assembly, the rack plate 9 can drive the piston 4 to move up and down in the solder storage tank 3 to realize the solder paste extrusion operation.

[0033] Reference Figure 1 The drive assembly includes a motor 8, which is fixedly connected to the outer wall of the mounting bracket 1. The motor 8 provides stable power output for the entire drive assembly. A rotating shaft 6 is fixedly connected to the output end of the motor 8. The rotating shaft 6 plays the role of transmitting power, transferring the rotational power of the motor 8 to the gear 7. A gear 7 is fixedly connected to the outer wall of the rotating shaft 6 and rotates with the rotation of the rotating shaft 6.

[0034] Reference Figure 4The fixing component includes a fixing block 15, which is fixedly connected to the front side of the mounting frame 1. The fixing block 15 provides the mounting base for the entire fixing component. Two limiting plates 17 are slidably connected inside the fixing block 15. The limiting plates 17 are used to limit the movement range of the connecting rod 18 and ensure the stability of the movement trajectory of the clamping plate 20. The connecting rod 18 is fixedly connected to one side of the limiting plate 17. The connecting rod 18 connects the limiting plate 17 and the clamping plate 20 and transmits the movement of the limiting plate 17 to the clamping plate 20. A spring 19 is fixedly connected to the other side of the limiting plate 17. The clamping plate 20 is fixedly connected to the side of the connecting rod 18 away from the limiting plate 17. The spring 19 is used to provide elastic force so that the clamping plate 20 can tightly clamp the discharge pipe 14.

[0035] Reference Figure 1 A pipe is provided between the solder storage tank 3 and the filter 13, so that the solder paste extruded from the solder storage tank 3 can be transported to the filter 13 for filtration through the pipe. An electromagnetic check valve 11 is provided on the outer wall of the pipe. When the extrusion assembly is working, 11 is opened, so that the solder paste flows from the solder storage tank 3 to the filter 13; when the extrusion assembly stops working, the electromagnetic check valve 11 is closed to prevent the solder paste from flowing back to the solder storage tank 3.

[0036] Reference Figure 1 The gear 7 and the rack plate 9 mesh with each other, which converts the circular motion of the gear 7 into the linear motion of the rack plate 9, thereby driving the piston 4 to move up and down in the solder storage tank 3 to extrude solder paste. An electromagnetic check valve 11 is provided at the connection between the filter 13 and the discharge pipe 14. When solder paste needs to be supplied, the electromagnetic check valve 11 opens, allowing the filtered solder paste to be transported to the use position through the discharge pipe 14. When it is not needed, it closes.

[0037] Reference Figure 4 Both the limiting plate 17 and the connecting rod 18 are square. The square structure can prevent the limiting plate 17 and the connecting rod 18 from rotating during the sliding process, thereby ensuring the accurate movement trajectory of the clamping plate 20. The outer wall of the connecting rod 18 is slidably connected to the inside of the fixing block 15, so that the connecting rod 18 can move smoothly under the restriction of the fixing block 15, thereby driving the clamping plate 20 to accurately complete the clamping and releasing actions.

[0038] Reference Figure 3 and Figure 4 The clamp 20 is arc-shaped, which can better adapt to the shape of the discharge tube 14 and make it easier to fix the discharge tube 14. The end of the discharge tube 14 away from the filter 13 is fixedly connected to the discharge port 16, which accurately delivers the filtered solder paste to the position where it is needed.

[0039] Reference Figure 4The end of the spring 19 away from the limiting plate 17 is fixedly connected to the inner wall of the fixing block 15, ensuring that the elastic force generated by the spring 19 during operation is effectively applied to the limiting plate 17.

[0040] Working principle: When solder paste needs to be extruded, motor 8 is turned on. The output end of motor 8 drives the rotating shaft 6 to rotate, and gear 7 rotates accordingly. Gear 7 rotates back and meshes with rack 9, driving rack 9 to move linearly. When rack 9 moves linearly, it drives piston 4 to slide downward inside solder storage tank 3 through connecting plate 10 and connecting rod 5. As piston 4 slides downward, it exerts pressure on the solder paste inside solder storage tank 3, and at the same time, opens the electromagnetic one-way valve 11 on the outer wall of solder storage tank 3, allowing the solder paste inside solder storage tank 3 to flow through the pipe to filter 13. Then, the solder paste is filtered by filter 13. Finally, the electromagnetic one-way valve at the bottom of filter 13... The valve 11 is opened, and the filtered solder paste is discharged through the discharge pipe 14 and the discharge port 16. When the solder paste supply is reached, the motor 8 is turned off. Then, the discharge pipe 14 is placed between the two clamping plates 20. When the discharge pipe 14 is placed, it will squeeze the two clamping plates 20, causing the clamping plates 20 to slide. This will drive the limiting plate 17 to slide through the connecting rod 18. At the same time, the spring 19 is squeezed, causing the spring 19 to store potential energy. When the discharge pipe 14 is placed, the spring 19 will release the stored potential energy, thereby pushing the limiting plate 17 to slide. This will drive the clamping plate 20 to slide through the connecting rod 18, thus fixing the discharge pipe 14.
