Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of quartz glass processing, and particularly relates to an automatic production equipment for a circular arc quartz plate and a processing method thereof. BACKGROUND

[0002] Quartz glass is widely used in the fields of electronic industry, optical industry, biological medical industry and aerospace industry due to its high hardness, high purity, low thermal expansion coefficient and good electrical insulation, etc. With the rapid development of the semiconductor equipment manufacturing industry, the demand for quartz glass products is also increasing. However, the processing technology of the quartz glass products is very strict, especially the production of circular arc quartz material.

[0003] At present, there are two main processing methods for producing circular arc quartz material. One is to cut a whole quartz block to produce a circular arc quartz plate with a required radius size by mechanical processing. However, this method will cause a large amount of material waste due to a large amount of cutting required. In addition, the processing period is also long, and a single machine tool needs to work for a long time to complete the processing of the required arc plate. This leads to high material and equipment costs.

[0004] The other method is to cut a thick quartz flat plate from a quartz block by mechanical processing, and then to soften and bend the flat plate by using a welding gun and a simple jig. At the same time, a special graphite jig is placed at the bottom, which is matched with the shape of the required circular arc plate. The worker manually bends the flat plate to match the shape of the quartz plate with the shape of the graphite jig at the bottom, so as to complete the processing of the required product. This method can greatly save the time required for mechanical processing and reduce the use of materials. However, since the product is manually softened and bent by the worker, the quality of the product is unstable, and the required circular arc radius and shape cannot be accurately bent. Therefore, in order to ensure the size accuracy, subsequent mechanical processing cutting is still required, which increases the processing cost. In addition, the flat plate needs to be left with a margin for subsequent processing during the cutting process, which leads to material waste. At the same time, during the bending process, the quartz plate will be stretched in thickness due to the bending of one end. SUMMARY

[0005] The application aims to provide an automatic circular arc quartz plate production equipment and a processing method thereof, which can solve the problems existing in the prior art, such as processing accuracy, processing period, material waste and processing cost.

[0006] To achieve the above-mentioned purpose, the following technical scheme is provided: an automatic production equipment for a circular arc quartz plate, comprising a rack, wherein the rack is provided with a workbench, and further comprising a

[0007] a bottom support assembly for supporting a quartz plate, the quartz plate being limited in a width direction thereof by the bottom support assembly, the quartz plate being movable on the bottom support assembly in a length direction thereof;

[0008] a fine burning assembly for fine burning the quartz plate in a vertical direction to soften the quartz plate;

[0009] a bending assembly for driving the softened quartz plate to make a circular arc movement to bend the quartz plate;

[0010] and a control unit for controlling the fine burning assembly and the bending assembly.

[0011] In the technical solution, compared with the traditional manual production mode, the automatic production equipment has the advantages of high automation efficiency, high production precision, low defect rate, cost saving, and support for large-scale production.

[0015] a constant force driving part for driving the rotating shaft to rotate and driving the rotating connecting rod to rotate to apply a constant force to the quartz plate, which can be bent after being softened.

[0016] In the technical solution, the rotating shaft is driven to rotate by the constant force driving part, and under the action of the constant force, the quartz plate will not be unevenly stressed to cause breakage, thereby improving the bending precision and the qualification rate of the quartz plate.

[0017] In any of the above technical solutions, further, the rotating shaft can be adjustably arranged in a length direction of the rotating connecting rod to change a rotation center of the rotating connecting rod, thereby adjusting a bending radius of the quartz plate.

[0018] The workbench is provided with a sliding seat capable of sliding thereon, the rotating shaft is arranged on the sliding seat in a vertical direction, and the rotating shaft and the rotating connecting rod are connected through a first adjusting piece;

[0019] The rotating connecting rod has a sliding groove opened in a length direction thereof, an upper end of the rotating shaft has an internal thread, and the first adjusting piece is a first screw handle which is screwed with the internal thread of the rotating shaft after passing through the sliding groove.

[0020] In the technical solution, the width and the bending radius of the arc-shaped quartz plate are different, and the following improvements are made to process the arc-shaped quartz plates with different bending diameters, that is, the rotating shaft is adjustably arranged in the length direction of the rotating link to change the rotating center of the rotating link and adjust the bending radius of the quartz plate.

[0021] In any of the above technical solutions, further, the constant force driving part comprises:

[0022] a first motor controlled by the control unit, an output shaft of the first motor being connected with the rotating shaft;

[0023] and a torque limiter arranged on the first motor and used for controlling the output torque of the first motor.

[0024] In the technical solution, the line layout is facilitated and the number of parts is reduced.

[0025] In any of the above technical solutions, further, the bottom support assembly comprises:

[0026] a linear guide block, a U-shaped slot for inserting the quartz plate being formed in the linear guide block;

[0027] a first bottom support pad arranged on the workbench, the first bottom support pad and the bottom of the U-shaped slot together providing support for the quartz plate; and

[0028] a second adjusting member arranged on the linear guide block and used for adjusting the slot width of the U-shaped slot to limit the quartz plate in the width direction;

[0029] The precision burning assembly is used for precision burning the area of the quartz plate between the linear guide block and the first bottom support pad.

[0030] In the technical solution, the bottom support assembly is used for supporting the quartz plate, and the linear guide block and the first bottom support pad are arranged to enable the quartz plate to move stably under external force.

[0031] In any of the above technical solutions, further, the bottom support assembly further comprises:

[0032] a second bottom support pad movably arranged on the workbench and used for supporting the bent quartz plate;

[0033] and a driving part used for driving the second bottom support pad to move.

[0034] The driving part is controlled by the control unit, after the quartz plate is softened by the fine burning assembly and is bent by the bending assembly, the control unit controls the driving part to move the second bottom support pad to the first bottom support pad and the chuck until the second bottom support pad is located at the bottom of the area of the quartz plate between the first bottom support pad and the chuck and supports the quartz plate.

[0035] In the technical solution, when the bending assembly bends the quartz plate to a certain length, the second movable bottom support pad is arranged to support the bent part of the quartz plate to avoid the softened quartz plate from being deformed downward under the action of its own gravity.

[0036] In any of the above technical solutions, the bottom support assembly further comprises:

[0037] The traction part is arranged on the front side of the linear guide block and pushes the quartz plate to move with a constant force while the softened quartz plate is moved in an arc by the bending assembly.

[0038] In the technical solution, since the quartz plate is only subjected to the traction external force of the bending assembly, the bending assembly has a stretching effect on the quartz plate during the bending process of the quartz plate after the quartz plate is softened, so that the bent quartz plate is easily stretched and deformed, thereby affecting the accuracy of the produced arc-shaped quartz plate.

[0039] In any of the above technical solutions, the bottom support assembly further comprises:

[0040] The guide part is arranged on the front side of the linear guide block and guides the linear movement of the quartz plate when the quartz plate is moved by an external force.

[0041] In the technical solution, after the quartz plate is subjected to the external force of the bending assembly, the quartz plate is subjected to a force in the bending direction, so that the quartz plate is not moved along a straight line, and finally the arc precision of the processed arc-shaped quartz plate is low.

[0042] In any of the above technical solutions, the fine burning assembly comprises:

[0043] The spray gun has two groups and is symmetrically arranged, and the quartz plate is located between the two spray guns.

[0044] Two guide rods are movably arranged on the workbench in vertical direction, and two spray guns are arranged on the two guide rods respectively;

[0045] A connecting cross rod is arranged to connect the two guide rods;

[0046] A third motor is arranged on the frame;

[0047] A rotating disc is arranged on the output shaft of the third motor, and an eccentric protrusion is arranged on the rotating disc;

[0048] and a crank is arranged, one end of which is connected with the eccentric protrusion, and the other end of which is connected with the connecting cross rod.

[0049] In the technical solution, the quartz plate needs to be completely softened in the height direction during the bending process, and the range of the flame sprayed by the spray gun is fixed, so the spray gun needs to move up and down at a constant speed to realize uniform softening of the quartz plate. Therefore, the above structure is arranged.

[0050] The beneficial effects of the present application are:

[0051] 1. Compared with the traditional manual production method, the automatic production equipment has the advantages of high automation, high production precision, low defect rate, cost saving, and support for large-scale production.

[0052] 2. For different circular arc quartz plates, the width and bending radius are different. Based on this, in order to process circular arc quartz plates with different bending diameters, the following improvements are made: the rotating shaft is adjustably arranged in the length direction of the rotating connecting rod to change the rotation center of the rotating connecting rod and adjust the bending radius of the quartz plate.

[0053] 3. Since the quartz plate is only subjected to external force of the bending assembly, after the quartz plate is softened, the bending assembly will also stretch the quartz plate during the bending process, which may cause the bent quartz plate to be stretched and deformed, thereby affecting the precision of the produced circular arc quartz plate. Therefore, a traction part is arranged, which can completely avoid this problem under the action of the front bending assembly and the rear traction part. After the linear velocities of the two are set to be consistent, the quartz plate is fed by the traction part and bent by the bending assembly. BRIEF DESCRIPTION OF DRAWINGS

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0067] Example 1:

[0068] like Figures 1-10 As shown, this embodiment provides an automated production equipment for an arc-shaped quartz plate 1, including a frame 100, a worktable 110 on the frame 100, and a base support assembly 200 disposed on the worktable 110 for supporting the quartz plate 1. The quartz plate 1 is limited in its width direction by the base support assembly 200, and the quartz plate 1 can move on the base support assembly 200 in its length direction.

[0069] The fine-firing component 300 is used to fine-firing the quartz plate 1 in the vertical direction to soften it;

[0070] The bending component 400 is used to drive the softened quartz plate 1 to make arc motion, so that the quartz plate 1 is bent.

[0071] And a control unit 500 for controlling the fine-firing assembly 300 and the bending assembly 400.

[0072] In the technical solution, an automatic device is designed for the traditional manual fine burning and bending mode. Specifically, the automatic device mainly comprises a bottom support assembly 200, a fine burning assembly 300, a bending assembly 400, and a control unit 500. First, the quartz material is cut into a strip-shaped plate structure, and then the quartz plate 1 is placed on the bottom support assembly 200. Subsequently, the fine burning assembly 300 is started by the control unit 500, the fine burning assembly 300 fine burns and softens the quartz plate 1. Then, the bending assembly 400 pulls the quartz plate 1 to move in an arc line. Since part of the quartz plate 1 is softened by fine burning, the softened area of the quartz plate 1 is bent when the bending assembly 400 applies an external force to the quartz plate 1. With the continuous traction of the bending assembly 400, the quartz plate 1 moves on the bottom support assembly 200 and is fine burned and softened by the fine burning assembly 300. Thus, the quartz plate 1 forms a curved arc structure. Finally, the excess part at both ends of the bent quartz plate 1 is cut off by the staff, and the required specification of the arc-shaped quartz plate 1 is obtained.

[0073] In general, compared with the traditional manual production mode, the automatic production device has the advantages of automation, high production precision, low defect rate, cost saving, and support for large-scale production.

[0074] Embodiment 2

[0075] The embodiment provides an automatic production device for an arc-shaped quartz plate 1. In addition to the technical solutions of the above embodiments, the automatic production device has the following technical features.

[0076] As shown in Figures 6-8 In the embodiment, the bending assembly 400 comprises:

[0077] a rotating shaft 410 arranged on the workbench 110;

[0078] a rotating connecting rod 420 connected to one end of the rotating shaft 410 and provided with a chuck 421 at the other end, the chuck 421 being used to clamp the quartz plate 1; and

[0079] a constant force driving part 430 configured to drive the rotating shaft 410 to rotate and drive the rotating connecting rod 420 to rotate, so as to apply a constant force to the quartz plate 1, which can be bent after being softened.

[0080] In the technical solution, in order to enable the quartz plate 1 to be bent and have high bending precision, the constant force driving part 430 is arranged to drive the rotating shaft 410 to rotate and drive the rotating connecting rod 420 to rotate. Since the end of the rotating connecting rod 420 is provided with the chuck 421, which clamps the quartz plate 1, the softened area of the quartz plate 1 can be deformed. Moreover, under the action of the constant force, the quartz plate 1 is not subjected to uneven stress, thereby preventing the quartz plate 1 from being broken.

[0081] As Figure 3 , Figure 5 and Figure 7 shown, in this embodiment, the optimization, for different circular arc-shaped quartz plate 1, the width size and bending radius are not the same, based on this, in order to process out the bending diameter of different circular arc-shaped quartz plate 1, the following improvements are made, the rotating shaft 410 can be adjustable in the length direction of the rotating link 420, to change the rotating center of the rotating link 420, and then adjust the bending radius of the quartz plate 1.

[0082] Specifically, the sliding seat 130 is fixed on the slide rail 120 by the second screw handle 131, or in the active state on the slide rail 120; the rotating shaft 410 is vertically arranged on the sliding seat 130, and the upper and lower ends of the rotating shaft 410 penetrate and extend out of the sliding seat 130.

[0083] The upper end of the rotating shaft 410 is connected with the rotating link 420 through the first adjusting piece; wherein the rotating link 420 has a sliding groove 422 opened along the length direction thereof, the upper end of the rotating shaft 410 has an internal thread, and the first adjusting piece is a first screw handle 423 which is screwed with the internal thread of the rotating shaft 410 after penetrating the sliding groove 422. When it is needed to adjust the bending radius of the quartz plate 1, only the first screw handle 423 and the second screw handle 131 need to be rotated, and then the sliding seat 130 is pushed to move. In the process of moving the sliding seat 130, the upper end of the rotating shaft 410 will slide along the inner wall of the sliding groove 422, that is, the sliding seat 130, the rotating shaft 410 and the rotating link 420 are linked together, and the movement of one part will drive the synchronous movement of the other two parts, so as to realize efficient adjustment. After the bending radius of the quartz plate 1 is adjusted, the first screw handle 423 and the second screw handle 131 are tightened, which is very convenient. In order to accurately adjust the displacement distance of the sliding seat 130, the slide rail 120 can be arranged perpendicular to the linear movement direction of the quartz plate 1, and the scale line 121 is arranged on the slide rail 120, so that the position of the sliding seat 130 can be known by observing the scale line 121, and then the bending radius of the quartz plate 1 can be calculated.

[0084] The constant force driving part 430 mainly comprises: a first motor 431 controlled by the control unit 500, an output shaft of the first motor 431 being connected with the rotating shaft 410; and a torque limiter 432 arranged on the first motor 431 and used for controlling the output torque of the first motor 431. The first motor 431 is fixed on the bottom of the sliding seat 130. In order to reduce the installation height of the sliding seat 130, a strip-shaped slot 211 can be formed on the workbench 110, the strip-shaped slot 211 being used for allowing the first motor 431 to pass downward and extend out of the workbench 110. When the sliding seat 130 slides along the length direction of the sliding rail 120, the first motor 431 slides on the strip-shaped slot 211. In this way, the line layout is facilitated, and an additional heightening table for heightening the sliding rail 120 is not needed, thereby reducing the parts for manufacturing.

[0085] For the rotating connecting rod 420, since it is only made of the rotating shaft 410, the load acting on the rotating shaft 410 is large, and the rotating connecting rod 420 is not stable in rotation. Therefore, a sliding support part is further arranged at the bottom of the rotating connecting rod 420, the bottom of the sliding support part abutting against and being able to slide on the workbench 110. The sliding support part is arranged close to the chuck 421, so as to improve the stability of the rotating connecting rod 420 in rotation. Of course, in order to reduce the friction between the sliding support part and the workbench 110, a sliding bearing can be arranged at the bottom of the sliding support part, so as to convert the sliding friction into rolling friction.

[0086] Embodiment 3:

[0087] The embodiment provides an automatic production equipment for a circular-arc quartz plate 1, in addition to the technical solutions in the above embodiments, and further has the following technical features.

[0088] As shown in Figure 1 and Figure 2 in the embodiment, the bottom support assembly 200 comprises:

[0089] a linear guide block 210, a U-shaped slot 211 for inserting the quartz plate 1 being formed on the linear guide block 210;

[0090] a first bottom support pad 220 arranged on the workbench 110, the first bottom support pad 220 and the bottom of the U-shaped slot 211 together providing support for the quartz plate 1; and

[0091] a second adjusting part 230 arranged on the linear guide block 210 and used for adjusting the slot width of the U-shaped slot 211, so as to limit the quartz plate 1 in the width direction.

[0092] The fine burning assembly 300 is used for fine burning the area of the quartz plate 1 between the linear guide block 210 and the first bottom support pad 220.

[0093] In the technical solution, the bottom support assembly 200 is used to support the quartz plate 1, and after the linear guide block 210 and the first bottom support pad 220 are arranged, the quartz plate 1 can move stably (i.e., the quartz plate 1 is fed) after being subjected to an external force.

[0094] Regarding the second adjusting part 230, it can be an adjusting bolt arranged on the linear guide block 210, and the length of the adjusting bolt extending into the U-shaped groove 211 is changed by rotating the adjusting bolt, so that the groove width of the U-shaped groove 211 is changed.

[0095] Embodiment 4:

[0096] The embodiment provides an automatic production equipment for a circular arc-shaped quartz plate 1, in addition to the technical solutions of the above embodiments, and has the following technical features.

[0097] As shown in Figure 1 and Figure 2 In the embodiment, the bottom support assembly 200 further includes:

[0098] The second bottom support pad 240 is movably arranged on the workbench 110 and is used to support the bent quartz plate 1;

[0099] and the driving part 250 is used to drive the second bottom support pad 240 to move;

[0100] The driving part 250 is controlled by the control unit 500, after the quartz plate 1 is softened by the fine burning assembly 300 and is bent to a certain length by the bending assembly 400, the control unit 500 controls the driving part 250 to move, so that the second bottom support pad 240 moves between the first bottom support pad 220 and the chuck 421, until the second bottom support pad 240 is located at the bottom of the region of the quartz plate 1 between the first bottom support pad 220 and the chuck 421 and supports the quartz plate 1.

[0101] In the technical solution, when the bending assembly 400 bends the quartz plate 1 to a certain length, in order to avoid the softened quartz plate 1 from being bent downward and deformed under the action of its own gravity, the movable second bottom support pad 240 is arranged, and the second bottom support pad 240 is used to support the bent part of the quartz plate 1.

[0102] In order to prevent the second bottom support pad 240 from interfering with the rotation of the rotary connecting rod 420, the second bottom support pad 240 can be movably arranged outside the path of the quartz plate 1, and after the bending assembly 400 bends the quartz plate 1 to a certain length, the driving part 250 drives the second bottom support pad 240 to move, so as to solve the interference problem.

[0103] The structure of the driving part 250 is not limited, and a cylinder, a hydraulic cylinder or an electric cylinder can be adopted, as long as the second bottom support pad 240 can be moved from the outside of the path of the quartz plate 1 to the path.

[0104] Embodiment 5:

[0105] The embodiment provides an automatic production equipment for a circular arc quartz plate 1, in addition to the technical solutions of the above embodiments, further having the following technical features.

[0106] As shown in Figure 2 , Figure 6 and Figure 9 , in the embodiment, the bottom support assembly 200 further comprises:

[0107] The traction part 260 is arranged on the front side of the linear guide block 210, and the traction part 260 pushes the quartz plate 1 to move with a constant force while the curved assembly 400 drives the softened quartz plate 1 to move in a circular arc.

[0108] In the technical solution, since the quartz plate 1 is only subjected to the traction external force of the curved assembly 400, after the quartz plate 1 is softened, the curved assembly 400 also has a stretching effect on the quartz plate 1 in the process of bending the quartz plate 1, so that the curved quartz plate 1 is easily stretched and deformed, the thickness changes, and the accuracy of the produced circular arc quartz plate 1 is affected. Therefore, the traction part 260 is further arranged, under the action of the front curved assembly 400 and the rear traction part 260, the problem can be completely avoided, after the linear velocities of the two are set to be consistent, the feeding of the quartz plate 1 is realized through the traction part 260, and the bending of the quartz plate 1 is realized through the curved assembly 400.

[0109] Specifically, the traction part 260 comprises:

[0110] The driving wheel 261;

[0111] The second motor 262 is connected with the driving wheel 261 and is used to drive the driving wheel 261 to rotate;

[0112] The driven wheel 263 cooperates with the driving wheel 261 to drive the quartz plate 1 to move in the form of friction;

[0113] The distance between the driving wheel 261 and the driven wheel 263 is adjustably arranged.

[0114] In the technical solution, the driving wheel 261 is arranged on the workbench 110 through the driving wheel 261 shaft bearing, the driven wheel 263 is arranged on the workbench 110 through the driven wheel 263 bearing seat, and the driving wheel 261 and the driven wheel 263 have a gap for inserting the quartz plate 1, and then the second motor 262 is arranged on the lower end face of the workbench 110 and connected with the driving wheel 261, so that the driving wheel 261 is driven to rotate through the rotation of the second motor 262, and finally the driving wheel 261 and the driven wheel 263 jointly drive the quartz plate 1 to move forward through the friction mode. The setting and the torque limiter 432 on the first motor 431 have the same effect, that is, the constant force driving of the quartz plate 1 is realized, and the quartz plate 1 is prevented from being damaged.

[0115] Because the thickness of the circular arc quartz plate 1 of different specifications also has a difference, the interval between the driving wheel 261 and the driven wheel 263 needs to be adjusted, and therefore the most practical solution is to set the driven wheel 263 as adjustable, to open a strip-shaped opening on the workbench 110, and then to arrange the driven wheel 263 bearing through the strip-shaped opening, and then to fix the driven wheel 263 bearing through bolts, so that the driven wheel 263 bearing can be adjusted by loosening the bolts when necessary, which is very convenient.

[0116] Embodiment 6:

[0117] The embodiment provides an automatic production equipment for a circular arc quartz plate 1, which comprises the technical solutions in the above embodiments and has the following technical features.

[0118] As shown in Figure 2 In the embodiment, the bottom support assembly 200 further comprises:

[0119] The guide part 270 is arranged on the front side of the linear guide block 210 and is used for guiding the linear motion of the quartz plate 1 when the quartz plate 1 is moved by external force.
