Description

Technical Field

[0001] The invention relates to the technical field of silver colloid feeding for stirring, in particular to a high-efficiency silver colloid feeding regulating device for stirring. Background Art

[0002] Conductive silver glue is an adhesive with certain conductive properties after drying. Its components are base resin and conductive filler, i.e. conductive particles. The mixing of conductive silver glue is a key step, which directly affects the performance and quality of conductive silver glue. Put the weighed resin, curing agent, diluent and other additives into the mixing tank and stir at a low speed for preliminary mixing. On the basis of preliminary mixing, gradually add conductive silver powder. Due to the large specific gravity of silver powder, it is necessary to stir while adding to ensure that the silver powder can be evenly dispersed in the resin matrix. After adding the conductive silver powder, increase the stirring speed and mix at high speed.

[0003] The speed of adding silver powder and the stirring speed jointly determine the quality of silver glue. For the production of high-quality silver glue, it is necessary to configure a highly sensitive sensor to monitor the stirring speed and adjust the silver powder dropping speed in real time according to the stirring speed.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the plates are adjusted to be away from each other, the feeding port is opened, and the silver powder falls onto the feeding disc, which rotates to continuously and evenly sprinkle the silver powder into the stirring tank; as the silver powder gradually decreases, the weight of the hopper decreases, the induction spring gradually pushes the hopper up, the hopper drives the baffle to rise, and the feeding pipe is blocked at the top to be blocked at the bottom, so that the amount of added silver powder is provided by the feeding disc alone, the feeding disc and the feeding pipe together, and finally the feeding disc alone again.

[0013] 2. In the present invention, when the silver powder is provided separately by the material dial, the silver powder is slowly added to the colloid to convert the colloid into a low-content silver colloid at the initial stage of high-speed operation of the corresponding stirring shaft.

If the concentration of the colloid increases too fast, it is easy to cause the stirring device to be overloaded or damaged. However, slowly adding the silver powder can slow down the growth rate of the concentration of the colloid, reducing the problem of the concentration of the colloid increasing too fast, causing the stirring device to be overloaded or damaged; 3.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 11The present invention provides a technical solution: a high-efficiency silver glue feeding regulating device for stirring, comprising a base 21, the base 21 is installed in a stirring tank 1, a stirring shaft 11 is arranged in a horizontal rotation in the stirring tank 1, and the stirring shaft 11 is fixed with stirring blades 12 arranged in a circular array; Specifically, the stirring shaft 11 drives the stirring blade 12 to rotate so as to fully mix the silver powder and the colloid, and the stirring shaft 11 is arranged horizontally so that the stirring blade 12 can continuously move up and down and continuously contact the bottom of the stirring tank 1 to prevent the silver powder from sinking to the bottom. The stirring blade 12 can be the same length as the stirring tank 1, further reducing the stirring blind area and further preventing the silver powder from sinking to the bottom, resulting in high local concentration.

[0019] Also includes: The hopper 22 is slidably arranged with the base 21, and an induction spring 23 is fixed between the hopper and the base 21; The feeding port 24 is arranged at the bottom of the base 21 and vertically overlaps with the bottom of the hopper 22; The adjusting plates 31 are slidably disposed at the bottom of the side wall of the base 21 and are arranged in pairs, and can control the feeding speed of the feeding port 24 by sliding relative to the feeding port 24; A synchronous structure, used to drive the adjustment plate 31 to move in the reverse direction; The material dispensing plate 41 is rotatably disposed at the bottom of the base 21 to receive and disperse the silver powder dropped from the feeding port 24; The feeding pipe 42 is fixed to the material dialing plate 41 and can conduct the feeding port 24 and the cavity of the mixing tank 1 to adjust the material dropping speed of the feeding port 24; The baffles 43 are arranged in pairs and are respectively arranged at the upper and lower ends of the feeding pipe 42. The baffles 43 are fixed together with the hopper 22 to adjust the silver powder flow rate of the feeding pipe 42 according to the up and down displacement of the hopper 22, thereby controlling the actual drop speed of the feeding port 24; The transmission structure is used to drive the material disc 41 to rotate to disperse the silver powder and increase the dispersion area and uniformity of the silver powder; The reciprocating structure drives the adjusting plate 31 to move in the opposite direction through the synchronous structure, so as to drive the adjusting plate 31 to slide relative to the feeding port 24 to control the opening size of the feeding port 24; The trigger structure drives the material-dispensing disc 41 to rotate through the transmission structure, and drives the adjustment plate 31 to move in the opposite direction through the reciprocating structure and the synchronous structure, so as to control the basic dispersing speed of the material-dispensing disc 41 according to the mixing speed of the mixing tank 1; Specifically, before use, a certain amount of silver powder is poured into the hopper 22, and the silver powder compresses the induction spring 23 through the hopper 22, and at the same time, the baffle 43 descends until the upper baffle 43 contacts and blocks the top of the feeding tube 42; When in use, the weighed resin, curing agent, diluent and other additives are initially mixed at a low speed. After the mixing is completed, the stirring shaft 11 is accelerated to rotate to make the trigger structure work. The trigger structure controls the material dial 41 to spread through the transmission structure and controls the basic spreading speed of the material dial 41 according to the mixing speed of the stirring tank 1. The trigger structure works, and the trigger structure controls the material-dispensing disc 41 to disperse the material through the transmission structure and controls the basic dispersing speed of the material-dispensing disc 41 according to the mixing speed of the mixing tank 1; The trigger structure drives the adjustment plate 31 to slide relative to the feeding port 24 through a reciprocating structure. The sliding distance of the adjustment plate 31 relative to the feeding port 24 is proportional to the mixing speed of the mixing tank 1, so that the opening size of the feeding port 24 is controlled according to the mixing speed of the mixing tank 1. The trigger structure drives the adjustment plates 31 to move away from each other through the reciprocating structure and the synchronous structure, and the feeding port 24 is connected to the stirring tank 1. The silver powder in the hopper 22 falls into the feeding plate 41 through the feeding port 24 in turn. At the same time, the trigger structure drives the feeding plate 41 to rotate through the transmission structure, and the feeding plate 41 drives the internal silver powder to rotate. The silver powder is thrown around and falls on the modulated mixed colloid under the action of centrifugal force. After the silver powder on the feeding plate 41 is thrown, the silver powder at the bottom of the hopper 22 falls on the feeding plate 41 again. The cycle is repeated to achieve continuous small amount of throwing, which can help to form silver powder particles with more uniform particle size and more regular shape. When the stirring shaft 11 drives the stirring blade 12 to rotate, the silver colloid is mixed with the colloid. The gravity of the silver powder in the hopper 22 gradually decreases, the induction spring 23 gradually overcomes the weight of the silver powder and pushes the hopper 22 to rise slowly, the hopper 22 drives the baffle 43 to gradually rise, the upper baffle 43 and the top of the feeding tube 42 gradually move away, the feeding tube 42 is connected to the stirring tank 1, and the silver powder falls into the stirring tank 1 through the feeding tube 42 at the same time. In this process, there are two forms of silver powder falling, and the falling speed is fast; when there is a small amount of silver powder in the hopper 22, the lower baffle 43 approaches the bottom of the feeding tube 42 until it fits, and the feeding tube 42 stops falling. A small amount of residual material in the feed pipe 42 can pass through the side hole ( Figure 5 Not marked in the figure, when the bottom of the feeding pipe 42 is open, the amount of silver powder that can directly enter the stirring tank 1 through the side hole has a negligible effect on the colloid viscosity and resistance in the initial stage) and is thrown out, the rapid material dropping stage is over, and the silver powder addition speed is slowed down again, which is conducive to the uniformity of silver powder mixing and avoids the extension of stirring time due to excessively high or low local concentration, thereby ensuring that this variable is stable and easy to control during the addition of silver powder; In summary, in the present invention, the adjusting plates 31 are moved away from each other to generate displacement relative to the feeding port 24, and the feeding port 24 is opened to allow the silver powder to fall onto the material dialing plate 41, and the material dialing plate 41 rotates to continuously and evenly sprinkle the silver powder into the mixing tank 1; As the gravity of the hopper 22 decreases, the baffle 43 gradually moves upward to open the feeding tube 42. During this process, there are two forms of silver powder falling, and the falling speed is fast until the baffle 43 on the lower side rises to close the feeding tube 42, and the fast falling stage ends.

[0020] As the silver powder gradually decreases, the weight of the hopper 22 decreases, and the induction spring 23 gradually pushes the hopper 22 upward, and the hopper 22 drives the baffle 43 upward. During this process, the feeding pipe 42 is blocked from the top to the bottom, so that the amount of silver powder added is changed from being provided by the material dial 41 alone to being provided by the material dial 41 and the feeding pipe 42 together, and finally to being provided by the material dial 41 alone again, thereby ensuring that the variable is stable and easy to control during the addition of silver powder; When the silver powder is provided separately by the material dial 41, corresponding to the initial stage of high-speed operation of the stirring shaft 11, the silver powder is slowly added to the colloid to convert the colloid into a low-content silver colloid. Since the specific gravity of the silver powder is relatively large, when the silver powder is added to the colloid, the concentration of the colloid will increase rapidly. If the concentration of the colloid increases too fast, it will cause a large instantaneous fluctuation in the resistance of the colloid, causing the mixing shaft to vibrate, which may easily cause the stirring device to be overloaded or damaged. However, slowly adding the silver powder can slow down the growth rate of the colloid concentration, reduce the instantaneous fluctuation of the resistance caused by the too fast increase in the concentration of the colloid, and protect the stirring device to avoid the problem of overloading or damaging the stirring device. The material dial 41 and the feeding tube 42 are provided together, corresponding to the intermediate stage of the stable high-speed operation of the stirring shaft 11, to increase the speed of adding silver powder, which can quickly change the low-concentration silver glue into medium-concentration silver glue, and can shorten the time of adding silver powder, thereby speeding up the production speed of silver glue; When the silver powder is provided separately by the feeding disc 41 again, corresponding to the final stage of the stable high-speed operation of the stirring shaft 11, the remaining silver powder can be slowly and evenly sprinkled onto the medium and high concentration silver glue to further ensure the uniformity of the reaction and reduce the subsequent stirring time; according to the before, middle and late stages of the high-speed movement of the stirring shaft 11, different amounts of silver powder are added to ensure the uniformity and speed of the silver powder, while protecting the stirring shaft 11.

[0021] The designed adding speed of silver powder is generally related to the mixing speed. In order to avoid complex control: As a further solution of the present invention, the trigger structure includes: The rotating ring 71 is rotatably arranged with the stirring tank 1 and fixed to the stirring blade 12 (the density of the silver powder and the other mixed materials is very different, and the purpose of connecting with the rotating ring 71 is to avoid the existence of a precipitation area at the bottom of the stirring tank 1); The gear ring 72 is axially slidably arranged with the rotating ring 71; The transmission gear 73 is meshed with the gear ring 72 and can slide relative to it. The side wall of the transmission gear 73 is provided with an annular groove 74; The induction ring 75 is axially slidably arranged with the rotating ring 71, the outer side of the induction ring 75 is located in the annular groove 74, and the induction ring 75 is fixed with a spring plate 76; The induction blocks 77 are arranged in a circular array and are radially slidably disposed with the rotating ring 71, and the induction blocks 77 are provided with trigger chamfers; For details, see Fig. 9 and Fig.10 When the stirring shaft 11 rotates at a high speed, the stirring blade 12 drives the rotating ring 71 to rotate at a high speed. The induction block 77 moves toward the outer wall of the rotating ring 71 under the action of centrifugal force and squeezes the induction coil 75 by triggering the chamfer, so that the induction coil 75 approaches the gear ring 72, contacts the spring plate 76 fixed to the induction coil 75 and continuously squeezes the gear ring 72. The end of the gear ring 72 away from the spring plate 76 is restricted by the rotating ring 71. The spring plate 76 and the rotating ring 71 limit the gear ring 72 from both sides respectively, so that the gear ring 72 is fixed relative to the rotating ring 71 at this time and can rotate with the rotating ring 71. The gear ring 72 is pressed by the spring plate 76 and rotates with the The centrifugal force of the induction block 77 increases, and the gear ring 72 can rotate with the rotating ring 71 after being squeezed. The gear ring 72 drives the transmission gear 73 meshing with it to rotate, and the transmission gear 73 drives the material dial 41 to rotate through the transmission structure, thereby realizing the rotation and material dialing of the material dial 41. The rotation of the material dial 41 is associated with the rotation speed of the stirring shaft 11, so that silver powder can be thrown into the stirring tank 1 when the stirring shaft 11 is stirred at a high speed, and the speed of the silver powder thrown by the material dial 41 is proportional to the rotation speed of the stirring shaft 11, which can further improve the uniformity of the silver powder mixing and effectively shorten the stirring time. The induction coil 75 also drives the transmission gear 73 to move along its own axial direction through the annular groove 74, and drives the reciprocating structure to work through the displacement of the transmission gear 73. The reciprocating structure drives the adjustment plate 31 to move in the opposite direction through the synchronous structure, thereby opening the bottom of the feeding port 24 and allowing the silver powder to fall onto the feeding plate 41; the opening size of the feeding port 24 is also proportional to the rotation speed of the stirring shaft 11, that is, as the rotation speed of the stirring shaft 11 increases, the opening size of the feeding port 24 also increases accordingly, and the rotation speed of the feeding plate 41 increases, which accelerates the scattering of the silver powder, and conversely reduces the scattering of the silver powder, which can also further improve the uniformity of the silver powder mixing.

[0022] It should be noted that the above descriptions are all about the motion state when the stirring shaft 11 rotates at high speed.

[0023] As a further solution of the present invention, the transmission structure includes: The transmission shaft 51 is slidably arranged with the transmission gear 73 through a key, and bevel gears 52 are installed at both ends of the transmission shaft 51; The reducer 53 is fixed to the base 21, and the output ends on both sides are provided with reduction gears 54, and the reduction gears 54 are respectively meshed with the bevel gear 52 and the material-dispensing plate 41; For details, see Figure 4and Figure 7 When the transmission gear 73 rotates, the bevel gear 52 is driven to rotate. The bevel gear 52 drives the material dial 41 to rotate through the reducer 53 and the reduction gear 54, so as to drive the material dial 41 to rotate to disperse the silver powder and increase the silver powder dispersion area and uniformity. The rotation speed of the material dial 41 is proportional to the rotation speed of the stirring shaft 11, and the silver powder throwing speed and range can be controlled according to the stirring speed, thereby further shortening the time required for silver powder mixing, thereby improving the efficiency of silver glue production.

[0024] As a further solution of the present invention, the reciprocating structure comprises: A connecting rod 61 is fixed to the adjusting plate 31, and a sliding shaft 62 is fixed to the end of the connecting rod 61; The lever 63 is rotatably arranged with the hopper 22, and has slide grooves 64 at both ends, and the slide grooves 64 are slidably arranged with the slide shaft 62; The cross bar 65 is rotatably arranged with the transmission gear 73; An adjustment frame 66, fixed to one of the connecting rods 61; For details, see Figure 6 and Figure 7 When the transmission gear 73 is displaced, the crossbar 65 moves accordingly and drives one of the connecting rods 61 to move through the adjustment frame 66, and the connecting rod 61 drives the adjustment plate 31 fixed thereto to move. With the movement of the adjustment plate 31, the feeding port 24 is opened, and when the stirring shaft 11 rotates at a high speed, the adjustment plate 31 is driven to slide relative to the feeding port 24 to control the opening size of the feeding port 24; the opening size of the feeding port 24 is proportional to the displacement distance of the transmission gear 73, that is, the opening size of the feeding port 24 is proportional to the rotation speed of the stirring shaft 11; the stirring shaft 11 rotates at a high speed, the silver powder is opened, and the opening size of the feeding port 24 is continuously controlled according to the stirring speed of the stirring shaft 11, the feeding of the silver powder is accurately controlled, and the uniformity of the silver powder is improved; When one of the connecting rods 61 moves, it can drive the sliding shaft 62 fixed thereto to move synchronously. The sliding shaft 62 drives the lever 63 to rotate through the sliding groove 64. The other side of the lever 63 drives the connecting rod 61 adjacent to it to move through the sliding shaft 62 on the same side, thereby realizing the synchronous delivery of silver powder from multiple feeding ports 24, increasing the delivery range of silver powder, and facilitating improving the mixing uniformity of the silver powder.

[0025] As a further solution of the present invention, the synchronization structure includes: The synchronous rack 34 is fixed on both sides of the adjustment plate 31; The synchronous gear 35 is located on both sides of the adjustment plate 31 and meshes with the synchronous rack 34; when the synchronous gear 35 rotates, the synchronous rack 34 meshed with it moves in the opposite direction; For details, see Figure 4 , Figure 5 and Figure 6When the connecting rod 61 drives one of the adjustment plates 31 to move, the two sides of the adjustment plate 31 move synchronously with the synchronous racks 34 fixed thereto, and the synchronous racks 34 drive the synchronous gears 35 meshing therewith to rotate. When the synchronous gears 35 rotate, the synchronous racks 34 fixed to the other adjustment plate 31 move in the opposite direction accordingly, thereby realizing the synchronous reverse movement of the adjustment plates 31, thereby controlling the opening size of the feeding port 24; realizing the two adjustment plates 31 to move toward or away from each other to realize the opening and closing of the opening; at the same time, the spacing between the adjustment plates 31 is in a multiple relationship with the displacement of the cross bar 65, which can enlarge the ratio of the opening to the displacement of the cross bar 65, increase the maximum limit of the opening, speed up the silver powder dropping speed, and shorten the silver glue preparation time.

[0026] As a further solution of the present invention, the upper surface of the adjustment plate 31 and the inner side of the hopper 22 are both inclined, which is beneficial to the discharge of silver powder, avoiding silver powder residue, affecting the proportion of silver powder in the silver glue, and reducing the quality of the silver powder.

[0027] As a further solution of the present invention, a gate plate 32 is slidably provided on the side wall of the base 21, a return spring 33 is fixed between the gate plate 32 and the base 21, and the bottom of the gate plate 32 is in contact with the upper surface of the adjustment plate 31; For details, see Figure 6 Since the upper surface of the adjustment plate 31 is inclined, when the adjustment plate 31 moves, the gap between the adjustment plate 31 and the base 21 gradually increases. The return spring 33 can prevent the silver powder from overflowing from the gap between the adjustment plate 31 and the base 21 by pressing down the gate plate 32, thereby affecting the proportion and speed of the silver powder addition; at the same time, pressing down the gate plate 32 can improve the stability of the adjustment plate 31 when it moves.
