Description

Technical Field

[0001] The present invention relates to the technical field of solder paste stirring devices, and in particular, to a high-efficiency solder paste mixer. Background Art

[0002] Solder paste is a new type of welding material that emerged with the advent of SMT. It is a paste-like mixture formed by mixing solder powder, flux, and other surfactants, thixotropic agents, etc. Solder paste has a certain viscosity at room temperature and can initially adhere electronic components in a predetermined position. At the welding temperature, as the solvent and some additives volatilize, the components to be soldered are welded to the printed circuit pads to form a permanent connection.

[0003] Solder paste needs to be stirred before use because it is made by stirring solder powder, solder paste, and solvent. The metal powder is heavier and sinks to the bottom, while the solvent is lighter and floats on the surface of the solder paste. This is why the surface of an un-stirred bottle of solder paste is covered with something like oil when opened. Stirring enables the solder powder and solvent components to be fully and evenly mixed, so that they can play the greatest role during welding. Most of the existing solder paste stirring devices stir the solder paste while exposing it to the air, and the solder paste is prone to oxidation and deterioration when exposed to the air, that is, the so-called black powder is generated in the solder paste, which will affect the use performance of the solder paste; at the same time, the stirring efficiency and stirring uniformity of the existing stirring devices are relatively low, and more bubbles are generated during stirring, which affects the quality of the solder paste.

[0019] Regarding the foregoing and other technical contents, features and effects of the present invention, they can be clearly presented in the following detailed description of the embodiments with reference to the attached Figures 1 to 14 In the detailed description of the embodiments, the structural contents mentioned in the following embodiments are all referenced to the accompanying drawings of the specification.

[0020] This embodiment provides a high-efficiency solder paste mixer, as shown in the attached Figures 1-14 figure. It includes an outer box 1 and a sealed box cover 2 hinged to the top thereof. Heating belts 31 for heating the inside of the outer box 1 are fixedly installed on the inner side walls of both the sealed box cover 2 and the outer box 1. After the heating belts 31 are powered on, they can heat a plurality of solder paste cans placed inside the outer box 1, so that the solder paste inside can have better fluidity, which is convenient for stirring. A lock is fixedly installed on the side of the sealed box cover 2, and a lock body is fixedly installed on the top of the side of the outer box 1. The outer box 1 and the sealed box cover 2 are hermetically connected to each other through the lock and the lock body; The inner bottom wall of the outer box 1 is fixedly connected with a fixed seat 3, and a vibration mechanism is arranged below the fixed seat 3. The vibration mechanism includes a vibration rod 9, a pulley 10, an eccentric wheel shaft 11, a bevel gear rod 12 and a first motor 13. The pulley 10 is rotatably connected to the bottom of the vibration rod 9, and the vibration rod 9 penetrates through the upper surface of the fixed seat 3. The number of the eccentric wheel shafts 11 is two, and both of the two eccentric wheel shafts 11 are rotatably connected inside the fixed seat 3 and respectively abut against the pulleys 10 at the bottoms of the two groups of vibration rods 9. The bevel gear rod 12 is connected to the output end of the first motor 13 by a spline, and the first motor 13 is fixedly installed on the side surface of the fixed seat 3. A support plate for supporting it is fixedly connected to one side of the fixed seat 3 close to the bevel gear rod 12. The bevel gear rod 12 penetrates through the inside of the support plate and can rotate inside it. One end of each of the two eccentric wheel shafts 11 close to the bevel gear rod 12 is fixedly connected with a bevel gear, and both are in transmission connection with the bevel gear rod 12 through the bevel gears. The tops of a plurality of vibration rods 9 are fixedly connected to the lower surface of the support plate 4; when the first motor 13 operates, it can drive the two eccentric wheel shafts 11 to rotate through the bevel gear rod 12, so that the eccentric wheel shafts 11 can push the pulleys 10 and the vibration rods 9. The faster the first motor 13 drives the bevel gear rod 12 to rotate, the faster the vibration frequency of the vibration rods 9 up and down, so as to vibrate the overall structure on the support plate 4; A support plate 4 is arranged at the top of the vibration mechanism, and a rotating mechanism is arranged on the lower surface of the support plate 4. A rotating seat 5 is arranged at the movable end of the rotating mechanism. The rotating mechanism includes a second motor 14, a first bevel gear 15 and a second bevel gear 16. The first bevel gear 15 is in spline transmission connection with the output end of the second motor 14, and the second motor 14 is fixedly installed on the lower surface of the support plate 4. The second bevel gear 16 is connected to the center of the lower surface of the rotating seat 5 through a rotating shaft, and the rotating shaft is rotatably connected to the center of the support plate 4 through a bearing. A ball bearing is fixedly installed at the center of the support plate 4, and a flat bearing is fixedly installed at the center of the upper surface. The rotating shaft of the second bevel gear 16 penetrates through the inner ring of the ball bearing. The lower surface of the rotating seat 5 is fixedly connected to the upper surface of the flat bearing. The ball bearing can reduce the frictional force on the side when the rotating shaft rotates, while the flat bearing can reduce the frictional force between the rotating seat 5 and the support plate 4, ensuring that the rotating seat 5 is subjected to a smaller frictional force when rotating. The second bevel gear 16 is arranged below the support plate 4 and meshes with the first bevel gear 15. When the second motor 14 drives the first bevel gear 15 to rotate, it can drive the second bevel gear 16 and the upper rotating seat 5 to rotate, so as to stir the solder paste in each of the upper solder paste cans, thus playing a certain role in stirring and mixing the solder paste; An annular groove is formed on the upper surface of the support plate 4. Four corners of the lower surface of the rotating seat 5 are fixedly connected with support rods, and the bottom ends of the support rods are rotatably connected with horizontally arranged rubber rollers. The four rubber rollers are rotatably connected in the annular groove in an annular array, which can play an auxiliary supporting role for the rotating seat 5, stably support the four sides of the rotating seat 5 and ensure the normal rotation of the rotating seat 5.

[0021] An arc-shaped card sleeve 6 is embedded in the upper surface of the rotating seat 5. Inside the arc-shaped card sleeve 6, a rotating frame 7 that can rotate inside it is rotatably connected, and a driving mechanism for driving the rotation of the rotating frame 7 is arranged on the side. The number of both the arc-shaped card sleeve 6 and the rotating frame 7 is several, and a rotating frame 7 is rotatably connected inside each arc-shaped card sleeve 6. Several arc-shaped card sleeves 6 are fixedly connected at equal intervals inside the rotating seat 5. The arrangement of multiple rotating frames 7 can stir multiple solder paste cans simultaneously, which is beneficial to improving the preparation efficiency before using the solder paste; Engaging teeth are fixedly connected to the outside of the rotating frame 7, and annular card slots 17 are opened on both sides. The driving mechanism includes a third motor 18 and a spur gear shaft 19. The spur gear shaft 19 is connected to the output end of the third motor 18 through a spline, rotatably connected to one side inside several arc-shaped card sleeves 6, and meshes with its corresponding rotating frame 7 through the engaging teeth. The third motor 18 is fixedly installed on the side of the arc-shaped card sleeve 6 at one end. When the third motor 18 drives the spur gear shaft 19 to rotate, it can drive multiple rotating frames 7 to rotate synchronously through the engaging teeth, so that the solder paste cans inside the rotating frame 7 can be rotated to an inverted state and rotate cyclically, enabling the bottom sediment and upper floating matter in the solder paste can to be inverted and mixed, so that they can be mixed together faster and the mixing uniformity is improved. Arc-shaped strips 20 that can cooperate with the annular card slots 17 are arranged on both sides inside the arc-shaped card sleeve 6. The arc-shaped strips 20 pass through the inside of the corresponding annular card slots 17, which can play a limiting role on the rotating frame 7 to prevent the rotating frame 7 from detaching from the arc-shaped card sleeve 6; A self-rotation mechanism for enabling the solder paste can to rotate by itself is arranged on the inner surface of the rotating frame 7, and a placement seat 8 for placing the solder paste can is arranged at the movable end of the self-rotation mechanism. The self-rotation mechanism includes mounting frames 21 and a fourth motor 22. The number of mounting frames 21 is two, and the two mounting frames 21 are respectively fixedly installed diagonally below both sides of the inner surface of the rotating frame 7. Fourth motors 22 are fixedly installed inside both mounting frames 21, and the output ends of the fourth motors 22 pass through the upper surfaces of the mounting frames 21 and are connected to the center of the bottom of the placement seat 8 through splines. The fourth motor 22 can drive the placement seat 8 to rotate, so that the solder paste can inside the placement seat 8 rotates by itself to stir the solder paste inside itself; Placement seats 8 are arranged on both sides inside the rotating frame 7, and the axes of the two placement seats 8 both correspond to the center of the rotating frame 7. The two placement seats 8 are symmetrically arranged with the vertical midline of the rotating frame 7 as the axis of symmetry, and the inclination angles are both forty-five degrees. The included angle between the extension lines of the axes of the two placement seats 8 is ninety degrees. The placement seats 8 on both sides correspond to the axis part during rotation, so that the centrifugal force generated by the solder paste can can be offset by the inclined placement seats 8 when the rotating seat 5 rotates, avoiding the solder paste can being thrown out of the placement seat 8; At the top of the inner wall of the placement seat 8, there is an elastic clamping member for clamping the side of the solder paste can. The elastic clamping member includes an arc-shaped rubber ring 23 and a compression spring 24. The arc-shaped rubber ring 23 is fixedly connected to the top of the inner wall of the placement seat 8, and the compression spring 24 is fixedly connected to the inside of the arc-shaped rubber ring 23. The number of elastic clamping members is four, and the four elastic clamping members are arranged in a circular array at the top of the inner wall of the placement seat 8. The compression spring 24 can exert an elastic force on the arc-shaped rubber ring 23 in the direction of the axis of the placement seat 8. When the solder paste can is inserted into the placement seat 8, it will squeeze the surrounding elastic clamping members, and the elastic clamping members can tightly press against the solder paste can placed in the placement seat 8, playing a fixing role for the solder paste can and ensuring that it is on the same straight line as the axis of the placement seat 8; At the top end of the placement seat 8, there is a locking mechanism for fixing and locking the top of the solder paste can. The locking mechanism includes a tension spring 25, a plug rod 26, an annular frame 27, a rotating ring 28, and an arc-shaped rod 29. Slots 30 adapted to the plug rod 26 are provided at the four corners of the upper surface of the placement seat 8. The tension spring 25 is fixedly connected to the bottom end of the plug rod 26, and the plug rod 26 is inserted into the slot 30. The bottom end of the tension spring 25 is fixedly connected to the inner bottom wall of the slot 30. The tension spring 25 can exert a pulling force on the plug rod 26 into the slot 30. The annular frame 27 is fixedly connected to the top end of the plug rod 26, and the rotating ring 28 is rotatably connected to the inside of the annular frame 27. The number of arc-shaped rods 29 is four, and the four arc-shaped rods 29 are rotatably connected to the inside of the annular frame 27 in a circular array. And one side of the arc-shaped rod 29 close to the rotating end is provided with meshing teeth. Corresponding parts of the inner surface of the rotating ring 28 and the rotating ends of the four arc-shaped rods 29 are also fixedly connected with meshing teeth. The rotating ring 28 can be meshed with the four arc-shaped rods 29 through the meshing teeth.

[0022] In the initial state, the plug rod 26 is completely inserted into the slot 30, the annular frame 27 is attached to the upper surface of the placement seat 8, and the four arc-shaped rods 29 are all in an open state and received inside the annular frame 27. After the solder paste can is inserted into the placement seat 8, the annular frame 27 can be lifted upward and the rotating ring 28 can be rotated counterclockwise. The four arc-shaped rods 29 are driven to rotate counterclockwise synchronously through the meshing teeth on the inner side wall of the rotating ring 28 and the rotating ends of the arc-shaped rods 29, so that the movable ends of the four arc-shaped rods 29 can all rotate above the placement seat 8. Release the annular frame 27, and the annular frame 27 can be pressed tightly against the top of the solder paste can in the placement seat 8 under the pulling force of the tension spring 25, playing a role of clamping and fixing the solder paste can to prevent the solder paste can from slipping outwards when the mixer is running.

[0023] On the front surface of the outer box 1, there are control buttons electrically connected to various internal electronic devices. All the electronic devices in this mixer are electrically connected to the control unit and are all controlled through the control buttons on the front surface of the outer box 1. And a timer can be set to time the running time of each electronic device, which is convenient for more precise control of the mixing progress.

[0024] The specific operation steps of this high-efficiency solder paste mixer are as follows: 1. Insert multiple solder paste cans into the corresponding placement seats 8 respectively. Lift the annular frame 27 upward and rotate the rotating ring 28 counterclockwise. The meshing teeth on the inner side wall of the rotating ring 28 and the rotating ends of the arc-shaped rods 29 drive the four arc-shaped rods 29 to rotate synchronously counterclockwise, so that the movable ends of the four arc-shaped rods 29 all rotate above the placement seats 8. Release the annular frame 27, and the annular frame 27 can be pressed tightly against the tops of the solder paste cans in the placement seats 8 under the pulling force of the tension spring 25, playing a role in clamping and fixing the solder paste cans; 2. Then tightly cover the sealed box cover 2 on the top of the outer box 1, and make the heating belt 31 operate to heat the inside of the outer box 1, and control the solder paste temperature at an appropriate temperature to avoid the reduction of the solder paste fluidity due to low temperature; 3. Run the fourth motor 22 and the third motor 18 simultaneously, which can make the solder paste rotate self - rotatably and also rotate in the vertical direction, so that the solder paste in the solder paste can is preliminarily stirred and also turned upside down and mixed up and down, improving the mixing uniformity; 4. After the third motor 18 runs for a period of time, readjust the two solder paste cans in the rotating frame 7 to the positions on the lower two sides, making the solder paste cans on both sides symmetrical, which can ensure that the forces on both sides are in balance when the rotating seat 5 rotates horizontally. Then stop the third motor 18, and then run the second motor 14 to rotate all the solder paste cans on the rotating seat 5, further improving the mixing uniformity of the solder paste; 5. When the stirring is completed, both the second motor 14 and the fourth motor 22 stop running, and the solder paste cans are in a static state. Then run the first motor 13, and perform high - frequency vibration on all the solder paste cans through the eccentric wheel shaft 11 and the vibrating rod 9 to discharge the gas in the solder paste and vibrate the solder paste adhering to the cover body, avoiding solder paste waste.
