Description

Technical Field

[0001] The utility model belongs to the technical field of electronic component production, and particularly relates to a glass powder stirring device. Background Art

[0002] A wafer refers to the silicon wafer used in the manufacture of semiconductor integrated circuits. Due to its round shape, it is called a wafer. Wafers can be processed into various circuit component structures, resulting in integrated circuit products with specific electrical functions. During the wafer production process for electronic components, glass powder is applied to the wafer to ensure a protective layer forms on the chip after dicing. Before applying the glass powder, it must be mixed with water to form a mixture. However, since glass powder is insoluble in water, it easily settles, which affects the application of the glass powder. Therefore, the glass powder must be constantly stirred to ensure thorough mixing with the water. Existing glass powder is manually stirred to prevent uneven mixing of the glass powder and water. However, manual stirring is not only labor-intensive but also produces poor mixing uniformity. Utility Model Content

[0003] In view of the above-mentioned shortcomings, the purpose of the present invention is to provide a glass powder stirring device, which solves the problem of high labor intensity and poor cutting uniformity in the prior art of manually stirring glass powder.

[0004] In order to achieve the above-mentioned purpose, the technical solution provided by the present utility model is:

[0005] A glass powder stirring device includes a mounting table, a roller group is provided on the mounting table, one end of the roller group is protruding from the outside of the mounting table and is provided with a drive gear, the drive gear is connected to a drive motor arranged below the mounting table through a gear belt, a plurality of stirring bottles are provided on the roller group, and the stirring bottles can rotate with the roller group, and zirconia beads are provided in the stirring bottles.

[0006] With the above-mentioned structural design, the roller group is driven to rotate by the driving motor, and then the stirring bottle installed on the roller group rotates automatically. While rotating, the zirconium oxide beads in the bottle can fully stir and mix the glass powder mixture in the stirring bottle. After stirring and mixing for a specified time, it can be used. The stirring device realizes automatic stirring of the glass powder, reduces the stirring intensity of the glass powder, and has higher uniformity than manual stirring, and is worthy of wide promotion.

[0007] As a further improvement, the roller group is multiple groups, and the roller group includes a driving roller and a driven roller. The two ends of the driving roller and the driven roller are respectively mounted on the mounting table through rotating bearings, and one end of the driving roller is provided with the driving gear.

[0008] The above structural design can increase the number of simultaneous stirrings, thereby increasing the stirring efficiency. At the same time, it is only necessary to set a driving gear on the active roller. After placing the stirring bottle on the roller group, the rotation of the active roller will drive the stirring bottle and the driven roller to rotate simultaneously, making the structure simpler.

[0009] As a further improvement, the driving roller and the driven roller are of the same size, and an anti-slip layer is provided on the outside of the driving roller and the driven roller respectively.

[0010] The above structural design can ensure the rotation and stability of the mixing bottle, and the problem of the mixing bottle not rotating due to slipping will not occur.

[0011] As a further improvement, the rotational speeds of the roller groups are different, and the sizes of the driving rollers and driving gears of adjacent roller groups are different.

[0012] With the above structural design, since the sizes of the driving rollers and driving gears of adjacent roller groups are different, the rotation speeds of adjacent roller groups can be different under the drive of the same drive motor, and thus the same stirring equipment can be used to meet different stirring requirements.

[0013] As a further improvement, height-adjustable limit columns are respectively provided on both sides of the roller assembly, and guide bearings are fixedly mounted on the upper ends of the limit columns.

[0014] As a further improvement, the stirring bottles are mounted on a roller assembly so as to abut against each other, and both ends thereof abut against the guide bearing.

[0015] By adopting the above-mentioned structural design, the mixing bottles are pressed against each other and fixed at the ends to ensure the consistency and stability of the rotation of the mixing bottles installed on the same roller group. Under the action of the guide bearing, the limit columns at both ends will not interfere with the mixing bottles and affect their rotation.

[0016] As a further improvement, the output end of the driving motor is provided with a driving gear, and the driving gear is connected to the driving gear through a gear belt.

[0017] As a further improvement, limiting plates are provided on both sides of the driving gear and the driving motor to prevent the gear belt from falling off.

[0018] As a further improvement, the diameter of the zirconia beads is 1.8-2.2 cm.

[0019] As a further improvement, a control switch is provided on the installation table, and the control switch is electrically connected to the drive motor and the reducer and time relay provided on the drive motor.

[0020] With the above structural design, different stirring times and stirring speeds can be set according to needs, thereby improving the versatility of the device.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The utility model drives the roller group to rotate by a driving motor, and then the stirring bottle installed on the roller group rotates automatically. During the rotation, the zirconium oxide beads in the bottle can fully stir and mix the glass powder mixture in the stirring bottle. After stirring and mixing for a specified time, it can be used. This stirring device realizes automatic stirring of the glass powder, which reduces the stirring intensity of the glass powder compared to manual stirring and has higher uniformity.

[0023] 2. The utility model provides two sides of the roller group with adjustable heights, and the upper ends of the limit columns are fixedly equipped with guide bearings, which can limit the two ends of the stirring bottle when the stirring bottle is placed, thereby ensuring the stability of the rotation of the stirring bottle. At the same time, the guide bearings can not only play a limiting role, but also ensure that they will not affect the rotation of the stirring bottle when in contact with the stirring bottle. The height adjustment of the limit columns can adapt to stirring bottles of different diameters. BRIEF DESCRIPTION OF THE DRAWINGS

The utility model drives the roller group 2 to rotate by the driving motor 5, and then the stirring bottle 6 on the roller group 2 rotates with the roller group 2. When the stirring bottle 6 rotates, the zirconia beads installed in the stirring bottle 6 can roll freely along the inner wall of the stirring bottle 6, thereby stirring and mixing the glass powder mixture in the stirring bottle 6.

[0032] The roller assembly 2 comprises multiple groups. In this embodiment, two groups are provided, but the scope of protection of this application is not limited to two groups. The roller assembly 2 includes a driving roller 2a and a driven roller 2b. The driving roller 2a and the driven roller 2b are of the same size. The two ends of the driving roller 2a and the driven roller 2b are respectively mounted on the mounting table 1 via rotating bearings 7. One end of the driving roller 2a is provided with the driving gear 3. When the driving roller 2a rotates, it drives the stirring bottle 6 and the driven roller 2b mounted above to rotate. At the same time, the driving roller 2a and the driven roller 2b are respectively provided with an anti-slip layer 2c, thereby ensuring that the stirring bottle 6 placed thereon can automatically rotate with the roller assembly 2.

[0033] Furthermore, the rotational speeds of different roller groups 2 are different, and the sizes of the driving rollers 2a and the driving gears 3 of adjacent roller groups 2 are different.

[0034] In another embodiment, the rotation speeds of the roller groups 2 are the same, and the driving rollers 2a and the driving gears 3 of adjacent roller groups 2 are the same in size.

[0035] The above-mentioned different designs can be adjusted according to the use requirements. When different stirring speeds are required during stirring, the design of this embodiment can be used. Otherwise, the design of another embodiment can be used.

[0036] Furthermore, height-adjustable limit posts 8 are provided on both sides of the roller group 2, and a guide bearing 9 is fixedly mounted on the upper end of the limit post 8.

According to the test results, the rotation stability of the stirring bottle 6 is higher in this way, and the glass powder in the bottle is mixed more evenly. Therefore, in this application, a guide bearing 9 is provided on the limit post 8 to rotate with the stirring bottle 6, thereby ensuring the smoothness of the rotation of the stirring bottle 6.

At the same time, the mounting table 1 in this application can adopt a mobile structure, and its volume and weight are small, making it easy to adjust its position and installation.

[0039] The working principle of this utility model is as follows:

[0040] When the glass powder stirring device of the present invention is used for stirring, first, a glass powder mixture in a certain proportion is placed into the stirring bottle 6. Then, multiple stirring bottles 6 are installed on the roller assembly 2, with the stirring bottles 6 in contact with each other and the head and tail of the stirring bottles 6 respectively in contact with the guide bearing 9. After the stirring bottles 6 are installed, the stirring speed and stirring time can be set through the control switch 11.
