Description

Technical Field

[0001] The invention belongs to the field of grinding technology, in particular to a conductive silver paste grinding machine for manufacturing electronic products. Background Art

[0002] Conductive silver glue is an adhesive with certain conductive properties after drying. Its components are base resin and conductive filler, namely conductive particles. my country's electronics industry is introducing and developing SMT production lines in large quantities. Conductive silver glue will inevitably have broad application prospects in my country. However, my country started late in research in this area, and the high-performance conductive silver glue required mainly relies on imports. Therefore, it is necessary to vigorously strengthen the research and application development of the influence of bonding temperature and curing time, bonding pressure, particle content and other factors on the reliability of conductive silver glue, and prepare new conductive silver glue to improve the international competitiveness of my country's electronic product packaging industry.

[0003] Since the conductive silver paste needs to be finely ground, the current roller equipment needs to use a shovel to manually shovel the mixture accumulated on the side back into the gap of the roller for cyclic processing during the grinding process. Therefore, the operation is too cumbersome, and in the process of repeated shoveling, it is easy for foreign impurities to be mixed into the colloid, so it needs to be improved.

[0006] The grinding component comprises a main motor, the outer surface of the output shaft of the main motor is rotatably connected to the main grinding column, the outer surfaces of the main motor are symmetrically provided with adjustment slides, the axis of the inner wall of the adjustment slide is slidably connected to the auxiliary motor through a pull rod, and the outer surface of the output shaft of the auxiliary motor is fixedly connected to the auxiliary grinding column.

During the sliding process of the special push plate, the conductive silver glue coated on the outer surfaces of the three grinding rotors can be pushed into the middle discharge component.

[0009] Furthermore, the discharge component includes a plug-in material box, the inner wall of the plug-in material box is plugged with a side partition, the top axis of the side partition is fixedly connected to a docking top frame, and the inner wall of the docking top frame is provided with a shock-absorbing component. The shock-absorbing component includes a control long plate, the left and right sides of the lower surface of the control long plate are symmetrically provided with limit arc plates, the bottom of the inner cavity of the control long plate is evenly provided with control impact rods, the middle part of the lower surface of the control long plate is plugged with the inner wall of the docking top frame, the bottom end of the control impact rod is pressed against the outer surface of the rotating shell, and after the side partition is inserted into the interior of the plug-in material box, the internal area of ​​the plug-in material box can be isolated from the outside.

[0010] Furthermore, the plug-in material box includes a sliding box shell, and the left and right sides of the inner cavity of the sliding box shell are symmetrically provided with through drainage ports, and the ground refined conductive silver paste can be squeezed into the interior of the sliding box shell through the through drainage ports, and sliding rods are evenly arranged on the bottom of the inner wall of the sliding box shell, and axis indicators are symmetrically arranged on the front and back sides of the inner wall of the sliding box shell, and a pressure-sensitive plate is fixedly connected to the middle of the inner wall of the axis indicator, and side pressure slides are symmetrically arranged on the left and right sides of the outer surface of the pressure-sensitive plate through connecting springs, and pressure push rods are evenly arranged on the side of the outer surface of the side pressure slide away from the pressure-sensitive plate.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. Due to the rotating transportation effect of the grinding cylinder, the ground colloid will continue to accumulate on the side of the auxiliary grinding cylinder, and thus cannot achieve the effect of continuous grinding. Therefore, during the grinding process of general roller equipment, manual shovels are required to continuously shovel the thick material accumulated on the side back into the gap of the roller. The device is provided with a rotating shell, which can collect the accumulated thick material, and transfer the thick material to the upper area by rotating, and put it on the outer surface of the grinding cylinder to achieve the effect of multiple grinding, thereby optimizing the processing procedure, achieving continuous and automatic processing effects, and eliminating the tedious manual operations.

[0014] 2. After grinding, the conductive silver glue sticky substance will be distributed on the outer surface of the grinding cylinder and the inner wall of the rotating shell. It is very difficult to recycle this part of the conductive silver glue using the general method. Therefore, a special push plate is provided inside the device. After grinding, the conductive silver glue inside the device can be uniformly transported to the discharge component in the middle by pushing the special push plate, so as to achieve the effect of recycling the conductive silver glue, thereby solving the problem that the conductive silver glue is difficult to effectively recycle and is prone to residual residue.

[0015] 3. The conductive silver glue processed by the device has a viscous property. When it is transported through the rotating shell, although the conductive silver glue can be poured onto the outer surface of the grinding cylinder by gravity, the actual effect may become poor due to the viscous property of the conductive silver glue. It is easy to have the problem that the conductive silver glue remaining inside the partition partition cannot be poured out. Therefore, a shock-absorbing component is set at the top. By controlling the impact rod to hit the rotating shell, the colloid is promoted to separate from the inner wall of the rotating shell, thereby solving the problem that the colloid is difficult to separate from the rotating shell.

[0016] 4. The device recycles the processed conductive silver glue viscous material through the plug-in material box. Since the through-drainage port can be blocked by the inserted side partition to achieve the effect of sealing the plug-in material box, the plug-in material box is in a relatively sealed state when it is taken out from the middle of the independent shell without affecting the recycling work. In the process of stirring the conductive silver glue, the conductive silver glue is also in a relatively sealed state, which makes it difficult to be doped with impurities during processing. Therefore, the obtained conductive silver glue is almost not contaminated by the external air, thereby improving the purity of the produced conductive silver glue. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0028] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a conductive silver paste grinding machine for electronic product manufacturing, comprising a stirring component 1, grinding components 2 are symmetrically arranged on the left and right sides of the inner wall of the stirring component 1, and a discharge component 3 is arranged in the middle of the stirring component 1;

[0029] The stirring component 1 comprises an independent shell 11, a rotating shell 12 is symmetrically arranged on the left and right sides of the inner wall of the independent shell 11, a partition plate 13 is evenly arranged on the inner wall of the rotating shell 12, a receiving groove 14 is opened on the side of the inner wall of the rotating shell 12 away from the discharge component 3, and an active roller shaft 15 is symmetrically arranged on the front and rear sides of the bottom of the inner wall of the independent shell 11;

[0030] The grinding component 2 includes a main motor 21, the outer surface of the output shaft of the main motor 21 is rotatably connected to the main grinding column 22, the outer sides of the main motor 21 are symmetrically provided with adjustment slides 23, the axis of the inner wall of the adjustment slide 23 is slidably connected to the auxiliary motor 24 through a pull rod, and the outer surface of the output shaft of the auxiliary motor 24 is fixedly connected to the auxiliary grinding column 25. The inner wall of the rotating shell 12 is rotatably connected to a special push plate 16 through a receiving rotation groove 14, and a solid push rod 17 is symmetrically provided on the side of the outer surface of the special push plate 16 away from the partition partition 13, and a compression sleeve 18 is sleeved on the side of the outer surface of the solid push rod 17 away from the special push plate 16. When the special push plate 16 is located in the receiving rotation groove 14 of the rotating shell 12, the rotating shell 12 can rotate relative to the special push plate 16. When the special push plate 16 slides along the partition partition 13 of the rotating shell 12, the special push plate 16 will be inserted into each complementary partition partition 13 through the groove on the outer surface.

[0031] The outer surface of the rotating shell 12 is rotatably connected to the inner wall of the independent shell 11, the outer surface of the special push plate 16 is plugged into the outer surface of the partition partition 13 through a complementary groove, the number of active roller shafts 15 is four, and the outer surface of the active roller shaft 15 is rollingly connected to the outer surface of the rotating shell 12.

[0032] The outer surface of the solid push rod 17 is slidably connected to the inner cavity of the independent shell 11 through a through hole, one side of the outer surface of the auxiliary grinding rotor 25 is rotatably connected to the inner cavity of the special push plate 16 through a slot, one side of the outer surface of the main grinding rotor 22 is rotatably connected to the axis of the inner cavity of the special push plate 16 through a slot, the outer surface of the main motor 21 is fixedly connected to one side of the inner cavity of the independent shell 11, and the three slots of the special push plate 16 are complementary to the main grinding rotor 22 and the auxiliary grinding rotor 25 respectively. During the sliding process of the special push plate 16, the conductive silver glue coated on the outer surfaces of the three grinding rotors can be pushed into the middle discharge component 3.

[0033] Before using the device to grind the conductive silver paste, first pull out the discharge component 3 in the middle, then add the mixed material to the middle position above the grinding components 2 on both sides through the slot opened in the middle of the independent shell 11, then insert the discharge component 3 into the middle of the independent shell 11, close the device, and complete the preparation work.

[0034] In the process of grinding the conductive silver glue, the main motor 21 drives the main grinding rotor 22 to rotate, and the auxiliary grinding rotors 25 on both sides drive the auxiliary grinding rotors 25 to rotate, and the gap between the main grinding rotor 22 and the auxiliary grinding rotor 25 is used to crush and refine the mixed material to form a colloid. In the above working process, the active roller 15 at the bottom of the independent shell 11 will drive the rotating shell 12 to rotate through the rotation friction force, and the colloid dripping onto the inner wall of the rotating shell 12 through the gap of the grinding rotor will be temporarily stored in the reserved area between the partition partitions 13. With the rotation of the rotating shell 12, it will be transported from the bottom to the highest point again, and then fall on the top of the grinding rotor, and will be ground again by the grinding rotor, thereby achieving the effect of cyclic grinding.

[0035] After a period of grinding, the formed conductive silver glue viscous material can be taken out from the inside of the device. At this time, stop rotating the active roller 15 to keep the rotating shell 12 in a stationary state. By pressing the external solid push rod 17, push the special push plate 16 toward the middle discharge component 3. The special push plate 16 is first plugged into each partition partition 13 of the rotating shell 12 through the reserved groove on the side, and then slides along the inner wall of the rotating shell 12. At this time, the special push plate 16 and the three grinding columns and the rotating shell 12 are all in a state of mutual filling. Therefore, the special push plate 16 will push the conductive silver glue on the outer surface of each grinding column and the conductive silver glue between the partition partitions 13 toward the middle during the movement, so as to achieve an effective pushing effect.

[0036] After the conductive silver paste is squeezed and pushed into the inside of the discharge component 3, the discharge component 3 is taken out from the middle of the independent shell 11 to obtain the stored conductive silver paste, thus completing the grinding of the conductive silver paste.

[0037] Example 2, please refer to Figure 1-Figure 9 The present invention provides a technical solution: on the basis of the first embodiment, the discharge component 3 includes a plug-in material box 33, the inner wall of the plug-in material box 33 is plugged with a side partition 31, the top axis of the side partition 31 is fixedly connected with a docking top frame 32, and the inner wall of the docking top frame 32 is provided with a shock component 4. The shock component 4 includes a control long plate 41, and the left and right sides of the lower surface of the control long plate 41 are symmetrically provided with a limited arc plate 42, and the bottom of the inner cavity of the control long plate 41 is evenly provided with a control striker 43. The middle part of the lower surface of the control long plate 41 is plugged with the inner wall of the docking top frame 32, and the bottom end of the control striker 43 is pressed against the outer surface of the rotating shell 12. After the side partition 31 is inserted into the plug-in material box 33, the internal area of ​​the plug-in material box 33 can be isolated from the outside.

[0038] The plug-in material box 33 includes a sliding box shell 331. The sliding box shell 331 has symmetrical through drainage ports 332 on the left and right sides of the inner cavity of the sliding box shell 331. The ground refined conductive silver paste can be squeezed into the interior of the sliding box shell 331 through the through drainage ports 332. The bottom of the inner wall of the sliding box shell 331 is evenly provided with sliding rods 333. The front and rear sides of the inner wall of the sliding box shell 331 are symmetrically provided with axis indicators 334. The middle part of the inner wall of the axis indicator 334 is fixedly connected with a pressure-sensitive plate 335. The left and right sides of the outer surface of the pressure-sensitive plate 335 are symmetrically provided with side pressure slides through connecting springs, and the side of the outer surface of the side pressure slide away from the pressure-sensitive plate 335 is evenly provided with pressure push rods 336. When the side partition 31 is inserted into the interior of the plug-in material box 33, the pressure push rods 336 on both sides will be squeezed into the interior of the axis indicator 334.

[0039] The left and right sides of the side partition 31 are plugged into the two sides of the inner wall of the sliding case 331 through the notches, the outer surface of the sliding case 331 is rotatably connected to the inner wall of the rotating shell 12 away from the special push plate 16, and the bottom of the sliding case 331 is plugged into the axis of the bottom of the inner cavity of the independent shell 11 through the sliding plug rod 333. The end of the pressure push rod 336 away from the pressure-sensitive plate 335 extends to the outside of the axis indicator 334, the inner wall of the side partition 31 and the end of the pressure push rod 336 away from the pressure-sensitive plate 335 are pressed against each other, and the outer surface of the axis indicator 334 is fixedly connected to the axis of the inner wall of the sliding case 331.

[0040] During the grinding process, the through drainage ports 332 on both sides of the sliding box shell 331 will be blocked by the side partitions 31 inserted into the inner wall, so that the unprocessed colloid will not enter the interior of the sliding box shell 331 through the through drainage ports 332, and the shock-absorbing component 4 connected to the top of the top frame 32 is working at this time, and the control impact rod 43 at the bottom is indirectly pushed downward through the control long plates 41 on both sides, so that the control impact rod 43 continuously hits the rotating outer shell 12 in a rotating state, so that the viscous material attached to the inner wall of the rotating outer shell 12 is more likely to fall off when it moves to the highest point.

[0041] When recovering the conductive silver glue that has been processed internally, the operator first pulls out the side partition 31 from the interior of the sliding box shell 331. At this time, the through drainage ports 332 on both sides of the sliding box shell 331 are opened. The colloid pushed by the special push plate 16 under pressure is squeezed into the interior of the sliding box shell 331 through the through drainage ports 332. Then, the side partition 31 is inserted into the interior of the sliding box shell 331 to close the sliding box shell 331. During the sliding process, the side partition 31 will squeeze the compressed push rods 336 on both sides toward the inner wall of the axis indicator 334. When the side partition 31 moves to the bottom of the sliding box shell 331, all the compressed push rods 336 are retracted into the interior of the axis indicator 334. At this time, the pressure-sensitive plate 335 is triggered, indicating that the plug-in material box 33 is in a sealed state.

[0042] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
