Description

Technical Field

[0001] This utility model relates to the technical field of solder paste mixing devices, and more specifically, to a high-precision fully automatic solder paste mixer. Background Technology

[0002] Solder paste is a key material used in electronic soldering. It is a paste-like substance made by uniformly mixing solder alloy powder and flux in a certain proportion and is widely used in surface mount technology.

[0003] Currently, commonly used solder paste mixers are difficult to open and close during use, are inconvenient to clean, and have low internal mixing efficiency. For example, a solder paste mixer disclosed in publication number CN115779766A includes a base assembly and a discharge component, with a bolt-assembled bearing assembly provided above one end of the base assembly.

[0004] As can be seen from the above-disclosed scheme, the clamp pot body is closed by the clamp pot lid, and the material is fed through the feed pipe, which makes it inconvenient to open and close the clamp pot lid, making it difficult to clean the inside of the clamp pot body. Furthermore, the material is stirred and mixed by the inclined stirring rod and crushing blade. Due to the small contact area with the solder paste material, the crushing and stirring efficiency is reduced. Moreover, when discharging, a large amount of solder paste is easily stuck to the inner wall of the clamp pot body, which causes inconvenience in use. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a high-precision fully automatic solder paste mixer. This high-precision fully automatic solder paste mixer, through the lifting mechanism consisting of a lifting motor, lead screw, guide rod, lifting plate, and lifting cover, can not only accurately lift and switch the mixing drum, but also facilitates the removal of the mixing mechanism from the mixing drum for thorough cleaning of the inside of the mixing drum. Furthermore, the blades, mixing frame, and scraper in the mixing mechanism not only increase the mixing efficiency but also automatically clean the inner wall of the mixing drum, improving ease of use.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A high-precision fully automatic solder paste mixer includes a solder paste mixer body, which includes a base. A bracket is fixedly connected to the surface of the base, and a positioning groove is formed on the surface of the base. A through hole is formed at the bottom of the positioning groove, and a mixing drum is fixedly installed on the inner wall of the positioning groove. A discharge nozzle is provided at the bottom of the mixing drum, and the surface of the discharge nozzle is movably connected to the inner wall of the through hole. A lifting mechanism is movably connected to the other end of the mixing drum, and a mixing mechanism is fixedly installed on the surface of the lifting mechanism. This high-precision fully automatic solder paste mixer, through the lifting motor, lead screw, guide rod, lifting plate, and lifting cover set in the lifting mechanism, can not only accurately lift and open the mixing drum, but also facilitate the removal of the mixing mechanism from the mixing drum for thorough cleaning of the inside of the mixing drum. Furthermore, the blades, mixing frame, and scraper set in the mixing mechanism can not only increase the mixing efficiency, but also automatically clean the inner wall of the mixing drum, improving the convenience of use.

[0008] Furthermore, the lifting mechanism includes a lifting cover, the bottom of which is provided with a plug-in part, and a sealing gasket is movably fitted onto the surface of the plug-in part. A lifting plate is fixedly connected to the side of the lifting cover, and the surface of the lifting plate is provided with screw holes and guide holes. The lifting cover can be lifted and moved under the action of the lifting plate, thereby automatically opening and closing the opening of the stirring drum.

[0009] Furthermore, a lead screw is threadedly connected to the inner wall of the screw hole, and a lifting motor is provided at one end of the lead screw. The end face of the lifting motor is fixedly connected to the top of the bracket, and a guide rod is fixedly connected to the bottom of the bracket. The surface of the guide rod is slidably connected to the inner wall of the guide hole. The guide rod and the lead screw can ensure the accuracy and stability of the lifting plate.

[0010] Furthermore, the mixing mechanism includes a stirring motor, the output end of which is provided with a rotating shaft. The surface of the rotating shaft is rotatably connected to a mounting plate via a sealed bearing. A stirring frame and a stirring rod are fixedly connected to the surface of the rotating shaft. The stirring frame and stirring rod can increase the contact area with the solder paste material and improve the mixing efficiency.

[0011] Furthermore, a countersunk hole is provided at the bottom center of the lifting cover, and a positioning hole is provided on the inner wall of the countersunk hole. The inner wall of the countersunk hole is movably connected to the surface of the mounting plate. A connecting hole is provided on the surface of the mounting plate, and a screw is fitted into the connecting hole. One end of the screw is threadedly connected to the inner wall of the positioning hole, so that after the lifting cover is raised, the mounting plate can be removed downwards, which facilitates the later maintenance of the mixing mechanism.

[0012] Furthermore, a scraper is slidably fitted onto the surface of the stirring frame, and a limiting plate is fixedly connected to one side of the scraper. A receiving groove is slidably connected to the surface of the limiting plate, and an elastic plate is fixedly installed on the inner wall of the receiving groove. The elastic plate allows the scraper to retract into the receiving groove, avoiding excessive wear against the inner wall of the stirring cylinder.

[0013] Furthermore, the stirring rods are evenly distributed along the length of the rotating shaft, and a blade is fixedly connected to one end of the stirring rod. The evenly distributed blades can increase the contact with the solder paste material and improve the crushing efficiency.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] This solution, through the lifting mechanism consisting of a lifting motor, lead screw, guide rod, lifting plate, and lifting cover, not only allows for precise lifting and lowering of the mixing drum, but also facilitates the removal of the mixing mechanism from the mixing drum, enabling thorough cleaning of the drum's interior.

[0016] This solution, through the blades, stirring frame, and scraper set in the mixing mechanism, can not only increase the mixing efficiency, but also automatically clean the inner wall of the mixing drum, thus improving the ease of use. Attached Figure Description

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. Example 1

[0025] Please see Figure 1-5 A high-precision fully automatic solder paste mixer is provided, which also includes a batching system, a conveying system, a control system, a feeding system, a temperature control system, and safety protection components. This facilitates precise batching, automatic feeding, and automatic mixing. It belongs to the prior art, and its composition and working principle are well known to those skilled in the art, therefore not described in this application. The mixer includes a solder paste mixer body 1, which includes a base 2. A bracket 21 is fixedly connected to the surface of the base 2. A positioning groove 22 is formed on the surface of the base 2, and a through hole 23 is formed at the bottom of the positioning groove 22. A mixing cylinder 24 is fixedly installed on the inner wall of the positioning groove 22. The inner wall of the mixing cylinder 24 is a heating plate, which can control the temperature of the solder paste raw materials through a temperature control system to improve mixing efficiency. A discharge nozzle 25 is provided at the bottom of the mixing cylinder 24, and a solenoid valve is provided on the discharge nozzle 25. The stirring drum 24 is movably connected to the inner wall of the through hole 23. The other end of the stirring drum 24 is movably connected to the lifting mechanism 3. The lifting mechanism 3 includes a lifting cover 31. The bottom of the lifting cover 31 is provided with a plug-in part. A sealing gasket is movably fitted on the surface of the plug-in part. A lifting plate 34 is fixedly connected to the side of the lifting cover 31. The surface of the lifting plate 34 is provided with screw holes 35 and guide holes 36. The lifting cover 31 can be lifted and moved under the drive of the lifting plate 34, thereby automatically opening and closing the opening of the stirring drum 24. A mixing mechanism 4 is fixedly installed on the surface of the lifting mechanism 3. The mixing mechanism 4 includes a stirring motor 41. The output end of the stirring motor 41 is provided with a rotating shaft 44. The surface of the rotating shaft 44 is rotatably connected to the mounting plate 42 through a sealed bearing. A stirring frame 47 and a stirring rod 45 are fixedly connected to the surface of the rotating shaft 44. The stirring frame 47 and the stirring rod 45 can increase the contact area with the solder paste material and improve the stirring efficiency.

[0026] A lead screw 37 is threaded into the inner wall of the screw hole 35. A lifting motor 38 is installed at one end of the lead screw 37. The end face of the lifting motor 38 is fixedly connected to the top of the bracket 21. A guide rod 39 is fixedly connected to the bottom of the bracket 21. The surface of the guide rod 39 is slidably connected to the inner wall of the guide hole 36. The guide rod 39 and the lead screw 37 can ensure the accuracy and stability of the lifting plate 34. A countersunk hole 32 is opened in the middle of the bottom of the lifting cover 31. A positioning hole 33 is opened in the inner wall of the countersunk hole 32. The inner wall of the countersunk hole 32 is movably connected to the surface of the mounting plate 42. A connecting hole 43 is opened in the surface of the mounting plate 42. A screw is sleeved in the connecting hole 43. One end of the screw is threaded into the inner wall of the positioning hole 33, so that after the lifting cover 31 is raised, the mounting plate 42 can be removed downwards, which is convenient for the later maintenance of the mixing mechanism 4.

[0027] A scraper 5 is slidably fitted onto the surface of the mixing frame 47. A limiting plate 51 is fixedly connected to one side of the scraper 5. A receiving groove 48 is slidably connected to the surface of the limiting plate 51. An elastic plate 52 is fixedly installed on the inner wall of the receiving groove 48. The elastic plate 52 allows the scraper 5 to retract into the receiving groove 48, avoiding excessive wear against the inner wall of the mixing cylinder 24. The mixing rod 45 is evenly distributed along the length of the rotating shaft 44. A blade 46 is fixedly connected to one end of the mixing rod 45. The evenly distributed blades 46 can increase the contact with the solder paste material and improve the crushing efficiency.

[0028] When using this high-precision fully automatic solder paste mixer, the control device is activated, causing the lifting motor 38 to operate. This, in turn, drives the lead screw 37 to rotate counterclockwise. The counterclockwise rotation of the lead screw 37 moves the lifting plate 34 upward, which in turn moves the lifting cover 31 upward. The lifting cover 31 opens the mixing drum 24, simultaneously causing the mixing mechanism 4 to move upward out of the mixing drum 24. Then, the solder paste raw materials are automatically added into the mixing drum 24 through the feeding system and conveying system. Next, the temperature control system heats and stabilizes the raw materials, while the lifting motor 38 drives the lead screw 37 to rotate clockwise. The rotation causes the lifting plate 34 and the lifting cover 31 to move downwards. The lifting cover 31 moves downwards and engages with one end of the mixing drum 24, sealing the opening. At this time, the rotating shaft 44, the mixing frame 47, the mixing rod 45, and the blade 46 are inside the mixing drum 24. Then, the mixing motor 41 starts working and drives the rotating shaft 44 to rotate, which in turn drives the mixing frame 47, the mixing rod 45, and the blade 46 to rotate and mix the materials. At the same time, the scraper 5 scrapes the material from the inner wall of the mixing drum 24. After the mixing is completed and the material is discharged through the discharge nozzle 25, the scraper 5 scrapes off the solder paste material adhering to the inner wall of the mixing drum 24, preventing a large amount of material from sticking to the inner wall of the mixing drum 24.

[0029] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
