After adding solvent, it can be made into a material or graphite-like substance. These pastes are applied to the required parts of the substrate by screen printing or other methods, and then fired at a temperature of 400~1000℃ to form a conductor. It is mainly used for the wiring of thick film integrated circuits, electrodes of ceramic capacitors, and leads of hybrid integrated circuits.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0029] Depend on Figure 1 and Figure 2As shown, it is a structural schematic diagram of the grinding and dispersing device for preparing conductive slurry in this embodiment, including a supporting base 1, a driving component 2, a connecting sleeve 3, a grinding wheel 4 and a clamping plate 5. A driving component 2 for driving the device is installed on one side of the surface of the supporting base 1, a connecting sleeve 3 is fixedly installed on the bottom end of the driving component 2, the output end of the driving component 2 passes through the connecting sleeve 3, and a grinding wheel 4 for material grinding and dispersion is installed at the end of the output end of the driving component 2. Clamping plates 5 are symmetrically arranged on the surface of the supporting base 1, and a moving mechanism 6 for controlling the position and spacing of the two groups of clamping plates 5 is installed at the bottom end of the clamping plate 5 inside the supporting base 1, and a limiting mechanism 7 for adjusting the position of the grinding wheel 4 inside the grinding barrel when the grinding wheel 4 is running is installed on the side of the clamping plate 5.

[0030] During use, a grinding barrel filled with conductive slurry is placed on the surface of the supporting base 1, and then the distance between the clamping plates 5 is adjusted through the operation of the moving mechanism 6, so that the subsequent limiting mechanism 7 can clamp and position the grinding barrel, thereby ensuring the stability of the grinding barrel during operation of the equipment. The limiting mechanism 7 can adjust and change the angle of the grinding barrel itself, change the position of the grinding wheel 4 when working in the grinding barrel, and comprehensively and efficiently grind the conductive slurry that forms eddy currents, thereby preventing a large amount of conductive slurry from flowing in the form of eddy currents along the inner wall of the grinding barrel, and preventing the grinding wheel 4 from being able to process such materials, thereby improving the overall working quality of the equipment.

[0031] By the attached Figure 4 As shown, it is a structural schematic diagram of the limiting mechanism 7 in this embodiment, the limiting mechanism 7 includes a rotating component 71, a side wall extrusion plate 72, a middle end connecting plate 73 and a bottom end supporting plate 74, the rotating component 71 is installed on the side of the clamping plate 5, the side wall extrusion plate 72 is fixedly installed at the end of the rotating component 71, the inner wall of the side wall extrusion plate 72 is in extrusion contact with the outer wall of the grinding barrel, the middle end connecting plate 73 is fixedly installed at the bottom end of the side wall extrusion plate 72, the bottom end supporting plate 74 is installed on the side of the middle end connecting plate 73 by bolts, and the bottom end supporting plate 74 provides support and positioning for the bottom end of the grinding barrel.

[0032] The side wall extrusion plate 72 and the bottom support plate 74 are pushed by the movement of the clamping plate 5 during use. When the side wall extrusion plate 72 and the bottom support plate 74 are moved to the target position, the grinding barrel filled with the conductive slurry is placed on the surface of the bottom support plate 74. The structure and shape of the bottom support plate 74 are used to support and reinforce the bottom of the grinding barrel. The side wall extrusion plate 72 can be used to squeeze and clamp the side wall of the grinding barrel, further lock the position of the grinding barrel itself, and ensure the position of the grinding barrel itself during subsequent grinding and dispersion. The use of the rotating component 71 can adjust the angles of the side wall extrusion plate 72 and the bottom support plate 74, drive the angle of the grinding barrel itself to change, change the position of the grinding wheel 4, which was originally perpendicular to the grinding barrel and located in the middle of the grinding barrel as a whole, reduce the distance between the grinding wheel 4 and the inner wall of one side of the grinding barrel, and change the running position of the grinding wheel 4 itself. At this time, in conjunction with the operation of the grinding wheel 4 itself, the original eddy current center is changed to ensure the overall grinding and dispersion effect of the equipment.

[0033] By the attached Figure 5 As shown, it is a schematic diagram of the structure of the rotating component 71 in this embodiment, the rotating component 71 includes a rotating connecting rod 711, a rotating connecting block 712 and a rotating arm 713, the rotating connecting rod 711 is rotatably installed inside the clamping plate 5, and the rotating connecting rod 711 passes through the clamping plate 5, one end of the rotating connecting rod 711 is fixedly connected to the side wall extrusion plate 72, the other end of the rotating connecting rod 711 is fixedly installed with a rotating connecting block 712, and the rotating arm 713 is fixedly installed outside the rotating connecting block 712.

[0034] The cam 720 of the embodiment of the present invention is a kind of camming tool which is used to move the handle 74 of the invention to the left and right sides of the workpiece 710. The cam 720 of the embodiment of the present invention is a kind of camming tool which is used to move the handle 74 of the invention to the left and right sides of the workpiece 710. The cam 720 of the embodiment of the present invention is a kind of camming tool which is used to move the handle 74 of the workpiece 710 to the left and right sides of the workpiece 710.

[0035] By the attached Figure 5 As shown, it is a schematic diagram of the structure of the rotating component 71 in this embodiment. The rotating component 71 also includes a limiting screw groove 714 and a limiting screw 715. The inner wall of the clamping plate 5 is equidistantly provided with limiting screw grooves 714, and there are multiple groups of limiting screw grooves 714. The limiting screw 715 is threadedly installed in the limiting screw groove 714.

[0036] During use, the initial position and height of the grinding wheel 4 are determined through the operation of the driving component 2 and the grinding wheel 4, and the insertion depth of the grinding wheel 4 in the grinding barrel is adjusted. The limit screw 715 is used according to the different positions of the grinding wheel 4 itself, and the positions of the two groups of limit screws 715 are locked by utilizing the cooperation of the limit screw groove 714. At this time, the rotating arm 713 is between the two groups of limit screws 715, and the swing amplitude of the rotating arm 713 itself is determined to prevent the rotating arm 713 from swinging too much during subsequent operation, resulting in the problem of contact between the grinding wheel 4 and the inner wall of the grinding barrel, thereby ensuring the stability of the equipment during operation.

[0037] By the attached Figure 3 As shown, it is a structural schematic diagram of the moving mechanism 6 in this embodiment, the moving mechanism 6 includes a driving motor 61, a bidirectional screw 62 and a moving end 63, the driving motor 61 is fixedly installed on the side of the support base 1, the bidirectional screw 62 is rotatably installed inside the support base 1, and the moving end 63 is symmetrically threadedly installed on the outside of the bidirectional screw 62, and there are two groups of moving ends 63, and the moving end 63 is fixedly connected to the bottom end of the clamping plate 5.

[0038] During use, the bidirectional screw 62 is rotated inside the support base 1 by starting the driving motor 61. The two sets of moving ends 63 move along the external threads of the bidirectional screw 62 by utilizing the cooperation between the bidirectional screw 62 and the moving end 63. The two sets of moving ends 63 drive the clamping plate 5 at the top to move toward the middle or to both sides at the same time, and adjust the distance between the two sets of clamping plates 5, so as to adjust the position of the clamping plate 5 according to the specifications of the grinding barrel itself when the equipment is used, and assist the subsequent components to be used stably.

[0039] By the attached Figure 3 As shown, it is a structural schematic diagram of the moving mechanism 6 in this embodiment, and the moving mechanism 6 also includes a guide rod 64, and the guide rod 64 is fixedly installed inside the support base 1, and the guide rod 64 is parallel to the bidirectional screw rod 62. The guide rod 64 is slidably connected to the moving end 63, and a sliding groove for cooperating with the sliding of the clamping plate 5 is opened on the upper surface of the support base 1.

[0040] During use, the moving trajectory of the moving end 63 is limited by the installation of the guide rod 64, so that the moving end 63 moves along a moving trajectory parallel to the surface of the supporting base 1, thereby ensuring the stability of the subsequent movement of the clamping plate 5. The opening of the sliding groove facilitates the connection and fixation of the moving end 63 and the clamping plate 5, thereby ensuring the stability of the component connection and improving the working quality of the equipment itself.

[0041] By the attached Figure 6As shown, an electric lifting rod is installed on the surface of the support base 1 located on the side of the driving component 2, and a connecting block is installed on the output end of the electric lifting rod, and the connecting block is fixedly connected to the side of the driving component 2.

[0042] During use, by installing and using the electric lifting rod, the height of the side drive assembly 2 and the grinding wheel 4 can be raised before use, so that the user can place the grinding barrel directly under the grinding wheel 4. After the position of the grinding barrel is fixed, the position of the drive assembly 2 and the grinding wheel 4 is pressed down by using the electric lifting rod. At this time, the connecting sleeve 3 and the parts outside the connecting sleeve 3 are fitted with the top opening of the grinding barrel to seal and shield the grinding barrel, thereby ensuring the stability of the conductive slurry inside the grinding barrel when the grinding barrel itself rotates, preventing splashing, and the electric lifting rod can flexibly adjust the height and position of the grinding wheel 4 in the grinding barrel, thereby expanding the working range of the equipment itself.

[0043] By the attached Figure 7 As shown, it is a structural schematic diagram of the sealing mechanism 8 in this embodiment. The grinding and dispersing device also includes a sealing mechanism 8 for sealing the top of the grinding barrel. The sealing mechanism 8 includes a limiting ring 81, a swing arm 82 and a sealing top cover 83. The limiting ring 81 is sleeved on the outside of the connecting sleeve 3, and the swing arm 82 is symmetrically rotatably installed on both sides of the limiting ring 81. The sealing top cover 83 is fixedly installed at the bottom end of the swing arm 82.

[0044] During use, the sealing mechanism 8 is installed on the outside of the connecting sleeve 3 by using the limiting ring 81, and then it is lowered together with the overall position of the driving assembly 2, so that the sealing top cover 83 is fitted with the top opening of the grinding barrel to seal and shield the top opening of the grinding barrel. When the angle of the grinding barrel itself changes, because the sealing top cover 83 is fitted with the top opening of the grinding barrel, the sealing top cover 83 will also tilt with the grinding barrel, and cooperate with the swing arm 82 to be able to rotate stably on both sides of the limiting ring 81, thereby ensuring the sealing of the grinding barrel itself during actual operation and preventing internal materials from splashing out.

[0045] By the attached Figure 7 As shown, it is a schematic diagram of the structure of the sealing mechanism 8 in this embodiment. The sealing mechanism 8 also includes an extrusion screw 84, which is threadedly installed on the side of the limiting ring 81, and the extrusion screw 84 passes through the limiting ring 81 and is in extrusion contact with the outer wall of the connecting sleeve 3.

[0046] During use, the depth of the grinding wheel 4 inserted into the grinding barrel varies according to the depth inside the grinding barrel and the liquid level of the material. The limiting ring 81 is pushed according to the position of the grinding wheel 4 itself, so that the limiting ring 81 slides on the outer surface of the connecting sleeve 3, and the overall height of the sealing mechanism 8 is flexibly adjusted. Then, the extrusion screw 84 is used to penetrate the limiting ring 81 and squeeze it into contact with the outer wall of the connecting sleeve 3, thereby locking the overall position of the limiting ring 81.

[0047] By the attached Figure 7 As shown, the limiting collar 81 has a swing groove inside to match the reciprocating swing of the swing arm 82, and the middle end of the sealing top cover 83 has a semicircular matching groove to assist its own swing.

[0048] The opening of the swing groove during use makes it easy for the swing arm 82 to drive the sealing top cover 83 at the lower end to swing along with the change of the angle of the grinding barrel itself, and a semicircular matching groove is opened inside the sealing top cover 83 to make the middle end of the sealing top cover 83 in a hollow state, thereby preventing the side wall of the sealing top cover 83 from contacting with the connecting sleeve 3 or the output end of the driving component 2 when the sealing top cover 83 swings subsequently, affecting the stability of the equipment during operation, thereby improving the working quality of the equipment itself.

[0049] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the scope of protection determined by the claims submitted for the present invention.
