Description

Technical Field

[0001] The present invention relates to the technical field of quartz product processing, and more specifically, to a quartz product bending device. Background Art

[0002] In the precision process of semiconductor chip manufacturing, quartz materials and their products play a vital role. They are not only indispensable support structures and reaction chamber consumables for performing key processes such as etching, diffusion, and oxidation, but also ensure the purity and efficiency of the production environment.

[0003] At present, the quartz cavity is welded by assembling the cut quartz plates, and the quartz glass welding rod and the two ends of the quartz plate to be welded are melted at the same time by heating with a high-temperature flame (hydrogen-oxygen flame above 3000 degrees), and the quartz welding rod is heated by the high-temperature flame to weld the two quartz plates together, and then the weld between the two plates is completely filled by the quartz welding rod to ensure the sealing between the two plates. This method is not only inefficient, but also requires a very high level of operator proficiency.

[0030] The distance between the two limiting surfaces is adjustable.

[0031] In any of the above technical solutions, further, the welding gun assembly includes:

[0032] A welding gun is used to heat the part of the quartz plate to be bent on the support platform by spraying fire from bottom to top;

[0033] and a first driving part, used for driving the welding gun to perform linear motion in the horizontal direction, so that the welding gun can evenly heat the part to be bent on the quartz plate;

[0034] The rotation axis of the support plate is colinear with the position to be bent of the quartz plate on the supporting platform.

[0046] S5. After a period of time, when the quartz plate is cooled, it is removed from the supporting platform and the process ends.

[0047] Beneficial effects: Compared with the prior art, the present application utilizes the quartz plate's own gravity to bend it. This method, on the one hand, reduces the experience requirements of the staff and reduces the difficulty of operation. The staff only needs simple training to take up the job, which is easy to operate. On the other hand, the quartz plate is bent by its own gravity and is not easy to break during the bending process.

[0061] The bending device and bending method of a quartz product of the present application are described in detail through the following embodiments.

[0062] Embodiment 1:

[0063] like Figure 1-Figure 5 As shown, in this embodiment, a quartz product bending device is proposed, comprising: a workbench 1; and a bearing platform 2 arranged on the workbench 1, for placing a quartz plate 10 and fixing the quartz plate 10; a support plate 3; an angle adjustment component 4, for adjusting the angle between the support plate 3 and the bearing platform 2; and a welding gun 51 component 5, for heating the portion to be bent of the quartz plate 10 on the bearing platform 2 to soften the portion to be bent of the quartz plate 10;

[0064] After the quartz plate 10 on the supporting platform 2 softens, one end of the quartz plate 10 bends under its own gravity and falls onto the supporting plate 3 .

[0065] The traditional way to bend the quartz plate 10 is to heat the quartz plate 10, and after it softens, apply external force to bend it into different angles. This operation method is very demanding on the experience of the staff and has extremely high requirements on the timing of applying the external force. Therefore, the present application uses the gravity of the quartz plate 10 to bend it. This method is not only simple to operate, but also not easy to cause damage to the quartz plate 10.

[0066] Specifically, the quartz plate 10 is placed on the supporting platform 2, and then the bottom of the bending part of the quartz plate 10 is heated by the welding gun 51 assembly 5. After the heated part of the quartz plate 10 softens, since one end of the quartz plate 10 is fixed, the other end will bend downward under its own gravity. After bending at a certain angle, it will rest on the supporting plate 3, thereby realizing the bending of the quartz plate 10.

[0067] In order to bend the quartz plate 10 at different angles, an angle adjustment component 4 is provided, and the angle of the support plate 3 is adjusted by the angle adjustment component 4 .

[0068] It should be noted that the end surface of the support platform 2 in contact with the bottom of the quartz plate 10 is in the same plane as the rotation axis of the support plate 3, and the end surface of the support plate 3 in contact with the bottom of the quartz plate 10 is in the same plane as the rotation axis of the support plate 3. This setting can achieve intuitive and precise control of the part to be bent of the quartz plate 10 after adjusting the angle of the support plate 3, and the rotation axis of the support plate 3 is the line to be bent of the quartz plate 10.

[0069] Embodiment 2:

[0070] This embodiment is a further improvement made on the basis of the first embodiment.

[0071] like Figure 3 and Figure 4 As shown, in this embodiment, the angle adjustment assembly 4 includes: a column 41, which is arranged on one side of the workbench 1; a rotating arm 42, one end of which is rotatably arranged on the column 41; a first motor 43, which is arranged on the column 41 and is used to drive the rotating arm 42 to swing;

[0072] One end of the support plate 3 is disposed on the other end of the rotating arm 42 , and when the rotating arm 42 rotates, the support plate 3 rotates simultaneously.

[0073] By setting a rotating arm 42, and then connecting the support plate 3 to the rotating arm 42, the rotating arm 42 is driven to rotate, thereby driving the support plate 3 to rotate, and then adjusting the angle of the support plate 3. In order to accurately control the rotation angle of the rotating arm 42, a first motor 43 is provided for this purpose, and by inputting the required angle value into the control system, the first motor 43 can drive the rotating arm 42 to rotate to the required position.

[0074] It should be noted that the angle adjustment assembly 4 further includes: an auxiliary bracket 44, which is arranged on the other side of the workbench 1; an auxiliary rotating platform 45, which is arranged on the auxiliary bracket 44; and an auxiliary arm 46, one end of which is arranged on the auxiliary rotating platform 45, and the other end is connected to the other end of the support plate 3;

[0075] When the rotating arm 42 rotates, the supporting plate 3 drives the auxiliary arm 46 and the auxiliary rotating platform 45 to rotate simultaneously.

[0076] In order to ensure the stability of the support plate 3, an auxiliary bracket 44, an auxiliary rotating table 45 and an auxiliary arm 46 are provided. These structures are used to support the end of the support plate 3 away from the rotating arm 42, thereby preventing the support plate 3 from tilting, resulting in an uncontrollable bending angle of the quartz plate.

[0077] It should be noted that although the angle of the support plate 3 can be displayed on the control panel and the staff can view it, if the first motor 43 fails or the staff enters the wrong parameters, the actual angle of the support plate 3 may not match the required rotation angle, causing the final product to be scrapped. For this reason, the angle adjustment component 4 also includes: an angle scale line, which is used to view the angle between the end face of the support plate 3 in contact with the bottom of the quartz plate and the end face of the support platform 2 in contact with the bottom of the quartz plate. After setting the angle scale line, it is convenient for the staff to clearly know the rotation angle of the support plate 3.

[0078] Embodiment three:

[0079] This embodiment is a further improvement made on the basis of any of the above embodiments.

[0080] like Figure 3 As shown, in this embodiment, the carrier 2 includes: a support seat 21, which is arranged on the workbench 1; a graphite base 22, which is arranged on the support seat 21, and is formed with a support surface 221 for supporting the quartz plate and a limiting surface 222 for limiting the two sides of the quartz plate; a clamp 23, which is arranged on the graphite base 22, and is used to clamp the quartz plate located on the support surface 221;

[0081] The distance between the two limiting surfaces 222 is adjustable.

[0082] Place the quartz plate to be bent on the supporting surface 221 of the supporting seat 21, and then adjust the supporting seat 21 so that the limiting surfaces 222 thereon limit the two sides of the quartz plate. Then push the quartz plate forward until the part to be bent of the quartz plate is aligned with the rotating axis of the rotating arm 42, and finally clamp the quartz plate by the clamp 23.

[0083] In this embodiment, it should be noted that the support seat 21 can be composed of two symmetrically arranged sliding seats, the two sliding seats can be close to each other or far away from each other, and the sliding seats can be fixed on the workbench 1 by bolts. The graphite base 22 has two, and is respectively arranged on the two sliding seats. Bosses protruding upward are arranged on the two graphite bases 22, and the opposite sides of the two bosses form limiting surfaces 222, which are used to limit the two sides of the quartz plate to avoid the quartz plate from tilting when the quartz plate is driven to move, resulting in the final bending position being offset from the actual bending position.

[0084] In this embodiment, it should be noted that the clamp 23 is a quick clamp.

[0085] In this embodiment, in order to facilitate the movement of the quartz plate, a strip protrusion is provided on the sliding seat perpendicular to the sliding direction thereof, and the upper end surface of the strip protrusion forms a supporting surface 221 for supporting the quartz plate.

[0086] Embodiment 4:

[0087] This embodiment is a further improvement made on the basis of the third embodiment.

[0088] like Figure 3-Figure 5 As shown, in this embodiment, it also includes: a baffle 6, which is arranged on the workbench 1 and is used to limit the end of the quartz plate located on the supporting platform 2 to control the position of the quartz plate to be bent;

[0089] The baffle plate 6 is arranged to slide in a direction approaching or moving away from the supporting platform 2 , and the workbench 1 is further provided with a second driving part 7 for driving the baffle plate 6 to perform linear motion.

[0090] The second driving part 7 is driven, and then the baffle 6 is used to push the quartz plate to move, so as to accurately control the position of the quartz plate.

[0091] Specifically, the second driving part 7 is a horizontally arranged screw module, and the baffle 6 is installed on the slider of the screw module. The push plate is driven to move by the screw module, and then the push plate is used to apply thrust to the quartz plate, so that the quartz plate can accurately reach the desired position and avoid deviations caused by manual adjustment.

[0092] Embodiment five:

[0093] This embodiment is a further improvement made on the basis of any of the above embodiments.

[0094] like Figure 3 and Figure 4 As shown, in this embodiment, the welding gun 51 assembly 5 includes: a welding gun 51, which is used to spray fire and heat the part to be bent of the quartz plate located on the carrier 2 from bottom to top; and a first driving part 52, which is used to drive the welding gun 51 to perform linear movement in the horizontal direction, so that the welding gun 51 uniformly heats the part to be bent on the quartz plate;

[0095] The rotation axis of the support plate 3 is colinear with the position of the quartz plate on the support platform 2 to be bent.

[0096] The welding gun 51 is an oxyhydrogen flame welding gun 51. By inputting hydrogen and oxygen into the welding gun 51, the welding gun 51 emits a high-temperature flame to heat the quartz plate. Since the part to be bent of the quartz plate is in the shape of a long strip, in order to heat the part to be bent, the welding gun 51 can be set to be in the shape of a long strip, and then, it has a plurality of nozzles for spraying flames in the length direction, and the quartz plate is heated by these nozzles.

[0097] In order to make the quartz plate heated evenly, the welding gun 51 is movably arranged, and then the nozzle is driven to move back and forth by the first driving part 52 to achieve the effect of even heating.

[0098] Specifically, the first driving part 52 includes: a crank slider mechanism 521, which is arranged on the workbench 1, and the slider on the crank slider mechanism 521 is connected to the welding gun 51; and a second motor 522, whose output end is connected to the crank chain on the crank slider mechanism 521, and is used to drive the crank to rotate so that the slider on it performs linear motion.

[0099] The second motor 522 drives the slider crank mechanism 521 to move, and then causes the slider on the crank mechanism to move linearly, thereby driving the welding gun 51 to move synchronously.

[0100] Embodiment six:

[0101] This embodiment proposes a method for bending a quartz product. The specific steps of the bending method are as follows:

[0102] S1, placing the quartz plate on the carrying platform 2, and after adjusting the position of the quartz plate to be bent, fixing it on the carrying platform 2;

[0103] S2. Use the angle adjustment component 4 to adjust the angle of the support plate 3;

[0104] S3, start the welding gun 51 assembly 5 to heat the part of the quartz plate to be bent;

[0105] S4, when the part to be bent of the quartz plate softens, the quartz plate automatically bends downward due to gravity until the bent end of the quartz plate contacts the support plate 3, and then the welding gun 51 assembly 5 is closed;

[0106] S5. After a period of time, when the quartz plate is cooled, it is removed from the supporting platform 2 and the process ends.

[0107] Using this method to bend the quartz plate, on the one hand, reduces the experience requirements of the staff and the difficulty of operation. The staff only needs simple training to take up the job, which is easy to operate. On the other hand, the quartz plate is bent by its own gravity and is not easy to break during the bending process.

[0108] Specifically, the quartz plate is first placed on the supporting platform 2, and then the position of the supporting platform 2 is adjusted so that the quartz plate is limited in the width direction; then the second driving unit 7 is controlled, and the second driving unit 7 drives the baffle 6 to move, and at the same time pushes the quartz plate to move, until the quartz plate moves to the desired position, and then the quartz plate is fixed by the quick clamp. At the same time, the first motor 43 is started, driving the rotating arm 42 to rotate, and adjusting the support plate 3 to a suitable angle; then the welding gun 51 and the first driving unit 52 are started, and the first driving unit 52 drives the welding gun 51 to perform linear motion, and the welding gun 51 heats the bottom of the quartz plate until it softens. After the quartz plate softens, the end of the quartz plate that is not fixed bends downward under the action of gravity and gradually falls on the support plate 3, and then the air inlet of the welding gun 51 is closed, so that the flame on the welding gun 51 is automatically closed. After a period of time, the quick clamp is released after the quartz plate is properly cooled, and the bent quartz plate is taken out, and the process ends.

[0109] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
