Description

Technical Field

[0001] The utility model belongs to the technical field of sand feeding devices, in particular to a uniform sand feeding device for a diamond production line. Background Art

[0002] With the rapid development of semiconductor, integrated circuit and photovoltaic industries, the application of hard and brittle materials such as sapphire and crystalline silicon is becoming more and more extensive, and higher requirements are also put forward for their cutting and processing technology. At present, the more mature cutting process is the free abrasive wire cutting technology, that is, supplying slurry with abrasive to the saw wire while cutting hard blanks. The main problems of this process are: the saw kerf loss is large and the yield is low; when cutting large-sized blanks, it is difficult for the abrasive to enter the long and deep kerf, and the cut surface flatness and surface quality are prone to defects; the circulation volume of the slurry is large, and a large amount of slurry needs to be recycled and processed; because the sawing action is based on the three-body wear principle between the cutting wire, the abrasive and the material to be cut, the abrasive will also act on the cutting wire, shortening its service life. In response to the problems faced by free abrasive wire saws, the consolidated diamond wire cutting technology that consolidates diamond abrasives on the cutting wire by composite electroplating has been gradually developed and expanded.

[0003] The sanding process of diamond abrasive is the most important and critical part of the production process of composite electroplated diamond wire. The difficulty lies in that during diamond composite electroplating, the steel wire is in a continuous routing motion, and it is relatively difficult for diamond to be consolidated on the steel wire. The sand particles bonded to the wire are easy to fall off under the triple effects of the relative movement of sand and wire, liquid resistance and fluid impact. The method of increasing the concentration of diamond micropowder in the plating solution is certainly helpful to enhance the consolidation ability by increasing the contact probability between sand and wire. However, since the density of diamond micropowder is much larger than that of the electroplating solution, and there is a certain adhesion between diamond micropowder particles, it is difficult to fully disperse the diamond micropowder particles in the electroplating solution. The poor dispersion effect will directly cause the diamond particles to agglomerate on the steel wire, and further lead to problems such as poor uniformity of the diamond wire diameter, easy breakage during cutting, deep cutting depth of the material to be cut, and scratches on the cutting surface.

[0004] The prior art sanding device, such as the Chinese utility model publication number CN206266726U, discloses a horizontal stirring sanding trough for producing high-efficiency composite electroplated diamond wire, including a sanding trough body, an overflow liquid circulation device, a horizontal stirring device, a steel wire conveying device, and an automatic feeding device; the sanding trough body includes three chambers, the middle chamber is a sanding area, and the two side chambers are overflow areas. The middle partitions of the three chambers are equipped with a liquid level adjustment plate, and the vertical grooves opened on the liquid level adjustment plate provide a routing channel for the steel wire. The liquid level height of the sanding area can be adjusted by the vertical groove width and plate height of the liquid level adjustment plate; the sanding area has an arc-shaped bottom structure, and a titanium basket is installed on one side of the sanding area, and a nickel ball is installed in the titanium basket. The titanium basket is connected to the positive electrode of the electroplating power supply, and the nickel ball is a sacrificial anode;

[0005] Although the above-mentioned patent is equipped with a reduction motor, a stirring shaft, and stirring blades, due to the action of gravity, sand is likely to sink to the bottom, resulting in poor uniformity of diamond micropowder particles. Therefore, we propose a uniform sand feeding device for a diamond production line. Utility Model Content

[0006] Aiming at the problems existing in the prior art, the purpose of the present utility model is to provide a uniform sand feeding device for a diamond production line. By providing a reduction motor, a main shaft, and stirring blades, it plays a stirring role, and at the same time, uniform oscillation is achieved through a vibration motor and a spring.

[0007] The present utility model is realized as follows. A uniform sand feeding device for a diamond production line includes a sand feeding trough body. A reduction motor is fixedly connected to the right side of the sand feeding trough body. The output shaft of the reduction motor penetrates the interior of the sand feeding trough body and is welded to the main shaft. A plurality of stirring blades are welded to the main shaft. Feed ports are respectively provided on the left and right sides of the sand feeding trough body. Connecting ears are respectively welded to the front and rear sides of the sand feeding trough body. A smooth rod is inserted into the interior of the connecting ear. A first limiting plate is fixedly connected to the middle and lower part of the smooth rod. A second limiting plate is fixedly connected to the top of the smooth rod. Springs are respectively provided on the upper and lower parts of the connecting ear. The springs are sleeved on the smooth rod. Brackets are respectively welded to the front and rear sides of the sand feeding trough body. The brackets are bolted with vibration motors.

[0008] The reduction motor is used to drive the main shaft and the stirring blades to ensure uniform mixing of abrasives and liquid media in the sand feeding trough body. In traditional sand feeding devices, uneven distribution of abrasives often occurs due to insufficient stirring, affecting the sand feeding effect. Through the low-speed and high-torque characteristics of the reduction motor in the present utility model, it is ensured that the stirring blades can effectively stir the substances in the trough body, improving the uniformity of sand feeding. Through the low-speed and high-torque characteristics of the reduction motor, gentle and effective stirring of the substances in the trough body is achieved. Compared with directly using a high-speed motor, the reduction motor can reduce the collision force between abrasives, avoid the crushing of abrasive particles, thereby maintaining a good particle size distribution, improving the sand feeding quality. Nickel balls are installed in the titanium basket. The nickel balls are sacrificial anodes. The titanium basket is connected to the positive electrode of the electroplating power supply, and the conductive wheel is connected to the negative electrode of the electroplating power supply. Through the fixed connection of the smooth rod, the bottom plate to the ground, and the design of the spring, it can cooperate with the vibration motor to make the sand feeding trough body vibrate up and down, making the mixing more uniform.

[0009] Optionally, a bottom plate is fixedly connected to the lower part of the smooth rod, and the bottom plate is connected to the ground through expansion bolts.

[0010] Optionally, a first liquid level adjustment plate and a second liquid level adjustment plate are fixedly connected to the interior of the sand feeding trough body.

[0011] Optionally, the lower part of the upper sand tank body is provided with a first overflow liquid outlet, a second overflow liquid outlet, and a third overflow liquid outlet.

[0012] Optionally, the first overflow liquid outlet and the second overflow liquid outlet are respectively connected with buffer boxes through connecting pipes.

[0013] Optionally, the buffer box is connected with a circulating pump through a connecting pipe, and the circulating pump is connected with the third overflow liquid outlet through a connecting pipe.

[0014] Optionally, the upper part of the upper sand tank body is connected with an upper cover through bolts, and a titanium basket is arranged inside the upper sand tank body.

[0015] Optionally, it further includes a conveyor wheel and a conductive wheel for conveying steel wires, and the steel wire penetrates through the upper sand tank body.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. Through the design of driving the main shaft and stirring blades by a reduction motor, the full mixing and uniform distribution of abrasives and liquid media are realized. The stirring blades can ensure the uniform dispersion of abrasives in the upper sand tank body, avoid too high or too low local concentration, and ensure the consistency of subsequent processing. Through effective stirring, the abrasives and liquid media are fully mixed, which not only improves the utilization efficiency of abrasives, but also reduces the quality problems caused by uneven distribution.

[0018] 2. Through the fixed connection of the smooth rod, the bottom plate and the ground, and the design of the spring, the fixation of the bottom plate and the ground enhances the stability of the entire device. The design of the spring can cooperate with the vibration motor to vibrate the upper sand tank body up and down, making the mixing more uniform.

[0019] 3. By setting the first liquid level adjustment plate and the second liquid level adjustment plate, as well as the multi-stage overflow ports and the circulation system, the precise liquid level control and recycling of the liquid medium in the upper sand tank body are realized. The liquid level adjustment plate can ensure the constancy of the liquid level height in the tank body, avoid affecting the sanding effect due to liquid level fluctuations; the overflow ports and the circulation system can recover the excess liquid, realizing the effective utilization of resources. The precise liquid level control ensures the best suspension state of the abrasives, thereby improving the sanding quality; the application of the circulation system reduces the production cost and is also more environmentally friendly.

[0027] As Figures 1 to 4 shown, a uniform sand feeding device for a diamond production line provided by an embodiment of the present utility model.

[0028] A reduction motor 2 is fixedly connected to the right side of the upper sand tank body 1. The output shaft of the reduction motor 2 penetrates through the inside of the upper sand tank body 1 and is welded with a main shaft 23. A plurality of stirring blades 24 are welded on the main shaft 23. Feed inlets 13 are respectively opened on the left and right sides of the upper sand tank body 1. Connecting ears 9 are respectively welded on the front and rear sides of the upper sand tank body 1. A smooth rod 10 is inserted into the inside of the connecting ear 9. A first limit plate 8 is fixedly connected to the middle and lower part of the smooth rod 10. A second limit plate 12 is fixedly connected to the top of the smooth rod 10. Springs are respectively arranged on the upper and lower parts of the connecting ear 9. The springs are sleeved on the smooth rod 10. Brackets 5 are respectively welded on the front and rear sides of the upper sand tank body 1. The brackets 5 are bolted with vibration motors 6.

[0029] A bottom plate 11 is fixedly connected to the lower part of the smooth rod 10. The bottom plate 11 is connected to the ground through expansion bolts.

[0030] A first liquid level adjustment plate 3 and a second liquid level adjustment plate 4 are fixedly connected to the inside of the upper sand tank body 1.

[0031] A first overflow liquid outlet 19, a second overflow liquid outlet 21 and a third overflow liquid outlet 20 are arranged at the lower part of the upper sand tank body 1.

[0032] The first overflow liquid outlet 19 and the second overflow liquid outlet 21 are respectively connected with a buffer box body 22 through connecting pipes.

[0033] The buffer box body 22 is connected with a circulation pump 7 through a connecting pipe, and the circulation pump 7 is connected with the third overflow liquid outlet 20 through a connecting pipe.

[0034] An upper cover 15 is connected to the upper part of the upper sand tank body 1 by bolts. A titanium basket 14 is arranged inside the upper sand tank body 1. Nickel balls are contained in the titanium basket 14. The nickel balls are sacrificial anodes. The titanium basket 14 is connected to the positive pole of the electroplating power supply, and the conductive wheel 17 is connected to the negative pole of the electroplating power supply.

[0035] It further includes a conveyor wheel 18 and a conductive wheel 17 for conveying the steel wire 16. The steel wire 16 penetrates through the upper sand tank body 1, and the conductive wheel 17 is connected to the negative pole of the electroplating power supply.

[0036] A reduction motor 2 is used to drive the main shaft 23 and the stirring blades 24 to ensure the uniform mixing of the abrasive and the liquid medium in the upper sand tank body 1.

[0037] Traditionally, the upper sand device often has uneven abrasive distribution due to insufficient stirring, which affects the upper sand effect. The utility model ensures that the stirring blades 24 can effectively stir the substances in the tank body through the low-speed and high-torque characteristics of the reduction motor 2, improving the upper sand uniformity.

[0038] Through the low-speed and high-torque characteristics of the reduction motor 2, gentle and effective stirring of the substances in the tank body is achieved.

[0044] Through the connection of the circulating pump 7 with the overflow port, the effective recovery and reuse of the excess liquid medium are realized, which not only saves resources but also reduces environmental pollution.

[0045] In summary, the key steps of the present utility model, from the design of the stirring mechanism, vibration control to liquid level regulation and recycling, etc., all reflect its remarkable advantages in improving the uniformity of sand feeding, ensuring the stable operation of the equipment and resource conservation.
