Description

TECHNICAL FIELD

[0001] The utility model relates to glass powder preparation mixing technical field, concretely is a kind of raw material rationing and mixing device for passivation glass powder preparation. BACKGROUND

[0002] In the preparation process of passivation glass powder, the mixing of raw materials is a crucial link. The traditional mixing method can realize the uniform mixing of different raw materials in the container to some extent, but there are serious deficiencies in the raw material ratio input link during mixing. At present, the feeding amount of various raw materials is mainly controlled by manual operation, which has many disadvantages.

[0003] Firstly, manual operation cannot ensure the accuracy of material feeding amount. Due to the skill level, operation concentration and experience difference of the operator, the actual feeding amount of the material will fluctuate every time the raw material ratio is adjusted. For example, when the addition amount of a certain key raw material such as fluxing agent needs to be accurately controlled, manual operation may result in over-adding or under-adding. If the addition amount of fluxing agent is too much, it will cause the melting point of glass powder to be excessively reduced, resulting in the problem of premature softening deformation of glass powder in the subsequent processing or use process, affecting the structural stability and physical properties of glass powder, and reducing its effectiveness as a passivation material. If the addition amount is too small, the fluxing agent cannot fully play its role, which will cause incomplete melting of glass powder and the presence of crystalline phase or un-melted particles, resulting in poor uniformity of glass powder and affecting its passivation effect on the device, causing device surface leakage and corrosion resistance to decrease.

[0004] Secondly, manual operation cannot guarantee the stability of each mixing. The difference in manual operation between different batches will make the quality of glass powder uneven. In large-scale production, such instability will seriously affect the consistency and reliability of the product, and it is difficult to meet the needs of modern industry for high-quality, standardized passivation glass powder products. For example, for the passivation glass powder used in electronic device packaging, unstable quality will cause the performance parameters of the packaged device to fluctuate greatly, reduce the yield of the product, and increase the production cost and after-sales risk.

[0005] Therefore, we propose a raw material rationing and mixing device for passivation glass powder preparation to solve the above problems. INVENTION CONTENTS

A vibration column 17 is fixedly connected to the top of the spring 16. The bottom end of the mixing chamber 2 is fixedly connected with a transfer pipe 18.

[0031] Please refer to Figures 1 to 6 As shown:

[0032] in:

[0033] The filling cone tube 3 is mainly used for filling raw materials.

[0034] The bottom end of the electric driving rod 4 is provided with a vertical sliding strip which is matched with a vertical groove in the inner wall of the adjusting column 8. Under the action of the vertical sliding strip and the vertical groove, the adjusting column 8 can move vertically on the electric driving rod 4 and can rotate with the electric driving rod 4.

[0035] The transfer pipe A 6 and the transfer pipe B 9 are used in cooperation and are mainly used for adjusting the amount of material added each time.

[0036] The telescopic part 7 is mainly used for controlling the distance between the rotating disc 5 and the adjusting column 8, that is, further adjusting the coincidence degree of the transfer pipe A 6 and the transfer pipe B 9.

[0037] The side view height of the adjusting ring 13 is different, and one side end is provided in a recessed state.

[0038] The convex strip 14 is mainly used in cooperation with the vibration column 17.

[0039] Under the action of the spring 16, the vibration column 17 can further knock the adjusting column 8 and indirectly drive the components thereon, so as to ensure that the added material is completely transferred to the bottom of the mixing bin 2 and avoid that part of the material is left on the transfer pipe A 6 or the transfer pipe B 9, which affects the accuracy of the mixing.

[0040] The transfer pipe 18 is used for transferring the mixed material.

[0041] Working principle:

[0042] Initial state: the filling cone pipe 3 is not coincided with the transfer pipe A 6, the transfer pipe B 9 is blocked by the blocking plate 10, the abutting column 11 is not in the recessed part of the adjusting ring 13, and the spring 16 is not compressed.

[0043] In use, the operator pours the material to be mixed into the filling cone pipe 3, and then starts the electric driving rod 4 of the device. The electric driving rod 4 rotates with the rotating disc 5 and the adjusting column 8. During the rotation of the rotating disc 5 and the adjusting column 8, the transfer pipe A 6 on the rotating disc 5 which is not coincided with the bottom end of the filling cone pipe 3 will be coincided with the filling cone pipe 3. At this time, the material in the filling cone pipe 3 will be communicated with the transfer pipe A 6 on the rotating disc 5 and enter the transfer pipe B 9 on the adjusting column 8. At this time, the material in the filling cone pipe 3 is transferred. With the continuous rotation of the rotating disc 5, the transfer pipe A 6 on the rotating disc 5 which is coincided with the filling cone pipe 3 is no longer coincided. At this time, the material in the filling cone pipe 3 cannot enter the transfer pipe A 6, and waits for the next coincidence.

[0044] Furthermore, after the material enters the temporary material storage bin composed of transfer pipe A6 and transfer pipe B9, as the electric drive rod 4 rotates with the adjustment column 8, the sealing plate 10 blocking the transfer pipe B9 will also rotate with the adjustment column 8 around the electric drive rod 4. During this process, the abutment post 11 fixedly connected to the sealing plate 10 will move from the plane of the adjustment ring 13 to the recess of the adjustment ring 13. When the abutment post 11 is located in the recess of the adjustment ring 13, the sealing plate 10 fixedly connected to the abutment post 11 will no longer block the bottom of the transfer pipe B9, and the material will fall to the bottom of the mixing bin 2.

[0045] Furthermore, if one wishes to adjust the single transfer volume of the temporary material storage bin formed by transfer pipes A6 and B9, this can be achieved simply by adjusting the extension of the telescopic component 7 to control the distance between the rotating disk 5 and the adjusting plate 8. When the distance between the rotating disk 5 and the adjusting plate 8 is adjusted, the overlap between the transfer pipes A6 and B9, which are fixedly connected to them, will also change. (See attached diagram.) Figure 5 and appendix Figure 6 That is, the material overlap is negatively correlated with the amount of material transferred in a single transaction; that is, the higher the overlap, the less material is transferred in a single transaction, and the lower the overlap, the more material is transferred in a single transaction.

[0046] Furthermore, during the process of transferring materials from the filling cone pipe 3 to the temporary material storage bin composed of the transfer pipe A6 and the transfer pipe B9, the rotating adjusting column 8 will rotate with the bottom protrusion 14 as the rotating axis of the electrically driven rod 4. During this process, the vibrating column 17 in the hollow column 15 will contact and move away from the protrusion 14. With the participation of the spring 16, the vibrating column 17 in the hollow column 15 will perform linear reciprocating motion. Under this motion, the vibrating column 17 will hit the adjusting column 8, thereby bringing vibration to the device and providing assistance for material transfer to prevent blockage and transfer.

[0047] Furthermore, since the side view height of the adjustment ring 13 is known to be different, one end of which is set to be concave, during the process of the abutment post 11 moving one circle on the upper surface of the adjustment ring 13, with the assistance of the hinge point on the transfer tube B9, the sealing plate 10 will perform the action of sealing and unsealing the transfer tube B9. Under this action, the intermittent injection of the agent from the injection cone tube 3 can be realized.

[0048] Further, through the design of quantitative proportioning, the product quality stability can be accurately proportioned to improve: the use of transfer pipe A6 and transfer pipe B9 can accurately control the feeding amount of various raw materials in the preparation process of passivation glass powder, and ensure the high consistency of raw material proportioning in each mixing operation. For example, the addition amount of key ingredients such as silicon dioxide, fluxing agent and fining agent can be accurately controlled within a very small error range, effectively avoiding the fluctuation of glass powder physical and chemical properties caused by inaccurate proportioning, which makes the produced passivation glass powder have excellent stability in key indicators such as melting point, viscosity and thermal expansion coefficient, significantly improves the reliability of the passivation glass powder as a passivation material in electronic device packaging application scenarios, reduces the risk of device failure caused by unstable glass powder quality, and greatly improves the product yield and overall quality level; secondly, improve the production efficiency and automation degree: the automatic quantitative proportioning of the device can automatically complete the proportioning and conveying of raw materials according to the preset formula parameters, without the need for repeated weighing and adding operations by manual operation; this not only greatly shortens the production cycle of each batch of products, improves the output per unit time, but also reduces the intermittent time and error adjustment time caused by manual operation, at the same time, improves the product quality after material mixing, and the automatic operation mode reduces the labor intensity and skill requirement of the operator.

[0049] Further, through the above design of improving proportioning accuracy by means of vibration function; the following benefits can be brought; first, significantly improve the proportioning accuracy: under the drive of the spring 16, the vibration column 17 can further knock the adjusting column piece 8 and the related components thereon, so as to ensure that the raw material filling amount is completely transferred to the bottom of the mixing bin 2, effectively prevent part of the raw material from remaining on the component transfer pipe A6 or the transfer pipe B9, avoid the adverse effect on the accuracy of proportioning and mixing, greatly improve the accuracy of passivation glass powder raw material proportioning, ensure the high consistency and stability of product quality, and lay a solid foundation for the excellent performance of subsequent products in various application scenarios;

[0050] Secondly, expand the applicability and flexibility of the device: the vibration accurate proportioning function makes the device can adapt to the mixing needs of various different characteristics of raw materials. Whether it is granular, powdered raw materials, or materials with different fluidity and viscosity, accurate quantitative proportioning and efficient transfer can be achieved under the action of vibration; the above wide applicability provides strong support for the diversification of passivation glass powder formula, and has strong versatility.
