Description

Technical Field

[0001] The present application relates to the field of automatic cleaning equipment for parts, and in particular to a cylindrical structure wall cleaning equipment. Background Art

[0002] In the production of single crystal silicon, the single crystal furnace is a critical piece of equipment. Temperatures inside the furnace reach thousands of degrees Celsius, and certain impurities in the raw materials evaporate or decompose, releasing gases or vapors. These volatiles, which may include silicon oxides and hydrocarbons, not only affect the purity of the single crystal but also corrode the heat field components, with the heater being the most severely affected by dust buildup. When volatiles accumulate on the walls of the cylindrical heater, the corrosive components in them can corrode the heater. If not cleaned promptly, this can affect the purity of the single crystal and the lifespan of the heater. Severe accumulation can even cause explosions and fires.

[0003] The traditional cleaning method involves disassembling the cylindrical heater and manually wiping it. This not only increases labor costs but also reduces production efficiency. Existing automated cleaning equipment can only clean the inner wall of the heater, while the outer wall still requires manual cleaning. This results in poor cleaning results and does not fully automate the cleaning of cylindrical workpieces. Utility Model Content

[0046] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0047] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0048] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0049] In order to solve the technical problem that the cleaning method of cylindrical structure workpiece in the prior art has poor cleaning effect and cannot fully realize fully automatic cleaning of cylindrical structure workpiece, the present application provides a cylindrical structure wall cleaning device, which can drive the brush holder assembly 2 and the brush assembly 1 to rotate through the driving assembly 3, and simultaneously realize the cleaning of the inner wall and the outer wall of the cylindrical structure through the brush assembly 1, and can realize fully automatic and all-round cleaning of the cylindrical structure wall, which is conducive to improving the cleaning effect and cleaning efficiency, reducing labor costs and improving production efficiency.

[0050] See also Figures 1 to 10 The embodiment of the present application provides a cylindrical wall cleaning device, including a brush assembly 1, a brush holder assembly 2 and a drive assembly 3, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown. The brush assembly 1 includes a first brush 11 and a second brush 12. The first brush 11 and the second brush 12 are arranged in parallel and sequentially along the radial direction of the cylindrical structure, and can be used to clean the inner wall and the outer wall of the cylindrical structure (i.e., the workpiece 10) respectively. There is a radial spacing between the first brush 11 and the second brush 12, and the radial spacing matches the thickness of the cylindrical wall of the cylindrical structure (i.e., the workpiece 10), so that the first brush 11 and the second brush 12 are respectively tightly attached to the inner wall and the outer wall of the cylindrical structure, as shown in FIG. Figure 5 shown.

[0051] A plurality of brush assemblies 1 are sequentially arranged along the circumference of the brush holder assembly 2, and the cleaning efficiency can be improved by using the plurality of brush assemblies 1. Figure 2 and Figure 5 As shown. The driving assembly 3 is connected to the brush holder assembly 2, driving the brush holder assembly 2 to rotate around the center of the brush holder assembly 2. At the same time, the brush assembly 1 set on the brush holder assembly 2 also rotates relative to the workpiece 10. One of the first brush 11 and the second brush 12 is used to clean the inner wall of the cylindrical structure, and the other is used to clean the outer wall of the cylindrical structure, thereby achieving fully automatic and all-round cleaning of the cylindrical wall of the workpiece 10.

[0052] Specifically, when three brush assemblies 1 are provided around the circumference of the brush holder assembly 2, the brush holder assembly 2 only needs to rotate 120° to clean the entire circumference of the workpiece 10. The first brush 11 and the second brush 12 are preferably linear roller brushes, and the brush heads are made of nylon, which are wear-resistant and corrosion-resistant, and can operate stably in a high-speed rotating working environment; while ensuring the cleaning effect, the brushes are prevented from causing wear on the wall surface of the cylindrical structure. When the first brush 11 is closer to the rotation center of the brush holder assembly 2, the inner wall of the cylindrical structure is cleaned by the first brush 11, and the outer wall of the cylindrical structure is cleaned by the second brush 12.

[0053] It should be noted that the workpiece 10 can be a cylindrical heater of a single crystal furnace, or can be other cylindrical structures whose walls need to be cleaned, which is not limited here. In the following embodiments of this application, the cylindrical heater in a single crystal furnace is used as the workpiece 10 to be cleaned.

[0054] In some embodiments of the present application, the brush assembly 1 also includes a first transmission assembly 13, which is respectively connected to the first brush 11 and the second brush 12. The first brush 11 and the second brush 12 are both rotatably arranged on the brush holder assembly 2. When the brush holder assembly 2 rotates, the first brush 11 and the second brush 12 can both rotate relative to the brush holder assembly 2 (that is, the first brush 11 rotates around the axis of the first brush 11, and the second brush 12 rotates around the axis of the second brush 12), so that the friction between the first brush 11 or the second brush 12 and the cylindrical structure is rolling friction rather than sliding friction, thereby avoiding the first brush 11 or the second brush 12 from using the same side surface for a long time to contact the wall of the cylindrical structure, and further avoiding the problems of high replacement and maintenance costs of the first brush 11 and the second brush 12 due to severe local wear.

[0055] In some embodiments of this application, please refer to Figure 2 、 Figure 3 and Figure 4 In order to drive the first brush 11 and / or the second brush 12 to rotate relative to the brush holder assembly 2, the driving assembly 3 also includes a second transmission assembly 31. The first brush 11 is located on the side of the second brush 12 close to the center of the brush holder assembly 2. The second transmission assembly 31 is connected to the first brush 11 and is used for the first brush 11 to rotate relative to the brush holder assembly 2. The first brush 11 then drives the second brush 12 to rotate through the first transmission assembly 13, so that the brush holder assembly 2 can be driven to rotate by the driving assembly 3 while the first brush 11 and the second brush 12 can be driven to rotate.

[0056] In some embodiments of this application, please refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The first transmission assembly 13 includes a first gear 131 and a second gear 132 that mesh with each other. The first gear 131 is coaxially arranged with the first brush 11, and the second gear 132 is coaxially arranged with the second brush 12. This can make the transmission structure between the first brush 11 and the second brush 12 compact, which is conducive to achieving meshing transmission when the distance between the first brush 11 and the second brush 12 is small.

[0057] The second transmission assembly 31 is a belt transmission assembly or a chain transmission assembly, which can drive the first brush 11 to rotate relative to the brush frame assembly 2 through a synchronous belt or a transmission chain. The first brush 11 is provided with a transmission part 111 connected to the second transmission assembly 31. Specifically, the transmission part 111 can be a synchronous pulley or a sprocket.

[0058] The driving assembly 3 also includes a coaxially arranged output shaft 32 and a transmission shaft 33. The output shaft 32 is connected to the brush holder assembly 2 to drive the brush holder assembly 2 to rotate synchronously. The output shaft 32 extends downward and forms a fixed connection with the transmission shaft 33. The transmission shaft 33 is connected to the second transmission assembly 31. When the output shaft 32 rotates, the transmission shaft 33 also rotates synchronously, thereby driving the synchronous belt or transmission chain in the second transmission assembly 31 to move. Specifically, when the second transmission assembly 31 is a belt drive assembly, the transmission shaft 33 is provided with a plurality of recessed pulley portions corresponding to the brush assemblies 1 one by one, such as Figure 4 When the second transmission assembly 31 is a chain transmission assembly, the transmission shaft 33 is provided with a plurality of sprocket transmission parts 111 corresponding to the brush assemblies 1 one by one.

[0059] In some embodiments of this application, please refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 6 The brush holder assembly 2 includes a connecting seat 21 and a plurality of connecting rods 22 radially connected along the circumference of the connecting seat 21. The first brush 11 and the second brush 12 are both rotatably set on the connecting rod 22. The connecting seat 21 is connected to the output shaft 32, and the connecting seat 21 can rotate synchronously with the output shaft 32; the connecting rod 22 and the connecting seat 21 are integrally connected and can rotate with the rotation of the connecting seat 21, thereby driving the brush assembly 1 to rotate relative to the workpiece 10.

[0060] In some embodiments of the present application, in order to improve the versatility of the cylindrical structure wall cleaning device, the connecting rod 22 can be set as a telescopic rod, and the cleaning of workpieces 10 of different diameters can be achieved by adjusting the length of the connecting rod 22.

[0061] In other embodiments of the present application, in order to improve the versatility of the cylindrical structure wall cleaning equipment, a plurality of connecting holes 222 can be set on the rod body 221 of the connecting rod 22, and the first brush 11 or the second brush 12 is detachably connected to the connecting hole 222, so that it can be used to clean workpieces 10 with different diameters or different wall thicknesses.

[0062] In some embodiments of the present application, please refer to FIG. Figure 2 、 Figure 4 、 Figure 5 and Figure 6 The brush rack assembly 2 also includes a reinforcing rod 23, which is connected between two adjacent connecting rods 22, and can connect the brush rack assembly 2 into a stable triangular structure, thereby improving the rigidity of the brush rack assembly 2 and preventing the brush rack assembly 2 from deforming during high-speed rotation and wall cleaning.

[0063] In some embodiments of this application, please refer to Figure 1 、 Figure 2and Figure 5 The drive assembly 3 also includes a drive motor 34 and a reduction gear box 35. The drive motor 34 is connected to the reduction gear box 35, and the output shaft 32 is connected to the reduction gear box 35. The rotational speed of the output shaft 32 can be adjusted to a reasonable range, thereby making the relative rotational speed between the brush assembly 1 and the wall of the workpiece 10 within a reasonable range, thereby avoiding wear on the barrel wall of the workpiece 10.

[0064] In some embodiments of this application, please refer to Figure 1 The cylindrical wall cleaning device further includes a protective cover 4, which is a cylindrical body with an opening at the bottom end and can be used to cover the workpiece 10. The brush assembly 1 and the brush holder assembly 2 are both arranged inside the cylindrical body and can rotate relative to the protective cover 4. The drive assembly 3 is arranged on the protective cover 4 to achieve fixed installation of the drive assembly 3. When cleaning the workpiece 10, the brush assembly 1 and the workpiece 10 are both located inside the protective cover 4, which can block volatile dust during the cleaning process, preventing dust from spreading over a large area, affecting the dust concentration inside the workshop, and avoiding adverse effects on the health of production personnel.

[0065] In some embodiments of this application, please refer to Figure 1 、 Figure 7 、 Figure 8 and Figure 10 The cylindrical wall cleaning device also includes a workbench assembly 5, which can be used to place a workpiece 10 to facilitate the fixation and cleaning of the workpiece 10. The protective cover 4 is movably mounted on the workbench assembly 5, allowing the protective cover 4, the brush assembly 1, the brush holder assembly 2, and the drive assembly 3 to move relative to the workpiece 10 as a whole, thereby facilitating the loading and unloading of the workpiece 10 on the workbench assembly 5. The protective cover 4, the brush assembly 1, the brush holder assembly 2, and the drive assembly 3 are integrally mounted on the workbench assembly 5, which facilitates the overall movement of the cylindrical wall cleaning device.

[0066] In some embodiments of this application, please refer to Figure 1 and Figure 7 The cylindrical structure wall cleaning equipment also includes a horizontal sliding component 6 and a lifting component 7. The horizontal sliding component 6 is arranged on the workbench component 5, and the lifting component 7 is connected between the protective cover 4 and the horizontal sliding component 6, so that the protective cover 4 and the brush assembly 1, the brush rack assembly 2 and the driving assembly 3 can be moved as a whole in the horizontal direction or vertical direction, thereby realizing the protective cover 4 and the brush assembly 1, the brush rack assembly 2 and the driving assembly 3 as a whole to avoid or cooperate with the workpiece 10.

[0067] Specifically, the slide rails 61 of the horizontal sliding assembly 6 are horizontally arranged on both sides of the workbench assembly 5, and the lifting assembly 7 is fixedly connected to the slider 62 of the horizontal sliding assembly 6, so that the lifting assembly 7 moves horizontally; the lifting assembly 7 is a pneumatic cylinder or a hydraulic cylinder, and the cylinder body of the lifting assembly 7 is fixedly connected to the slider 62. The telescopic end of the lifting assembly 7 is connected to the protective cover 4, which can drive the protective cover 4 to move vertically. When it is necessary to place the workpiece 10 on the workbench assembly 5, the slider 62 of the horizontal sliding assembly 6 is slid toward one side of the workbench assembly 5, and then the workpiece is loaded from the other side of the workbench assembly 5; then the protective cover 4 is raised by the lifting assembly 7 so that the bottom of the protective cover 4 is higher than the top of the workpiece 10, and then the lifting assembly 7 and the protective cover 4 are slid above the workpiece 10 by the horizontal sliding assembly 6. The lifting assembly 7 is lowered, and the first brush 11 and the second brush 12 clamp the wall of the workpiece 10. The drive assembly 3 is started to clean the wall of the workpiece 10. When the cleaned workpiece 10 needs to be removed from the workbench assembly 5, the lifting assembly 7 lifts the protective cover 4 until the bottom of the protective cover 4 is higher than the top of the workpiece 10, and then the lifting assembly 7 and the protective cover 4 are slid to one side of the workbench assembly 5 through the horizontal sliding assembly 6 until there is no interference between the workpiece 10 and the lifting assembly 7 and the protective cover 4.

[0068] In some embodiments of the present application, to achieve relative positioning between the brush holder assembly 2 and the workpiece 10, a positioning post 53 extending vertically is provided on the workbench assembly 5, and a positioning hole 331 is provided on the drive shaft 33 of the drive assembly 3. The relative positioning between the brush holder assembly 2 and the workpiece 10 is achieved through the cooperation between the positioning post 53 and the positioning hole 331. To prevent the positioning post 53 from interfering with the loading and unloading of the workpiece 10, the positioning post 53 is detachably connected to the main body of the workbench assembly 5. To prevent the positioning post 53 from interfering with the rotation of the drive shaft 33, a clearance fit is provided between the positioning post 53 and the positioning hole 331.

[0069] In some embodiments of the present application, a centering limit point corresponding to the position of the positioning column 53 is provided on the slide rail 61 of the horizontal sliding assembly 6. When the slider 62 moves to the centering limit point, the positioning column 53 and the positioning hole 331 can be aligned, so that after the lifting assembly 7 is lowered, the positioning column 53 and the positioning hole 331 can be positioned and matched, thereby realizing the relative positioning between the brush rack assembly 2 and the workpiece 10.

[0070] It should be noted that the positioning column 53 and the centering limit point can be set at the same time, or one of them can be set selectively, and both can achieve the purpose of this application.

[0071] In some embodiments of the present application, please refer to FIG. Figure 1 、 Figure 7 and Figure 10In order to realize the positioning and deformation detection of the workpiece 10, a placement groove is provided on the workbench assembly 5. The placement groove is an arc-shaped groove. The size of the arc-shaped groove is the same as the size of the standard workpiece. When the workpiece 10 can be completely embedded in the placement groove, it means that the workpiece 10 is accurately positioned and there is no deformation, and cleaning can continue. When the workpiece 10 cannot fit into the placement groove, it means that the workpiece 10 is deformed and maintenance is required before cleaning can continue.

[0072] Specifically, the workbench assembly 5 has a first placement groove 511 and a second placement groove 521 that are arranged opposite to each other, and can perform deformation detection on the cylinder walls on both sides of the workpiece 10 respectively.

[0073] In some embodiments of the present application, when the workpiece 10 is a single crystal furnace heater, since the heater cylinder 101 has downwardly extending legs 102 on both sides, it will interfere with the table surface of the workbench assembly 5. If the legs 102 are disassembled before cleaning, it will result in a large amount of parts disassembly and assembly work during the cleaning process.

[0074] In order to solve the above problems, in some embodiments of the present application, the workbench assembly 5 includes a first workbench 51 and a second workbench 52. The first workbench 51 is located in front of the second workbench 52, and the first workbench 51 and the second workbench 52 are connected in a convex shape. When the heater is loaded horizontally from the first workbench 51 to the second workbench 52, the width on both sides of the first workbench is smaller than the distance between the two legs 102, so the legs 102 can be avoided. Before cleaning the heater cylinder 101, there is no need to disassemble the legs 102.

[0075] In some embodiments of this application, please refer to Figure 1 The cylindrical structure wall cleaning equipment also includes a walking wheel assembly 8 and an armrest assembly 9. The walking wheel assembly 8 is arranged at the bottom of the workbench assembly 5, and the armrest assembly 9 is arranged on one side of the workbench assembly 5. The walking wheel assembly 8 can be rolled by pushing the armrest assembly 9, thereby realizing the overall movement of the cylindrical structure wall cleaning equipment.

[0076] Specifically, the armrest assembly 9 is arranged on the side of the second workbench 52 away from the first workbench 51, and the walking wheel assembly 8 includes four movable wheels with shock-proof function, which can be used to carry a cylindrical structure with a certain weight, so that the cylindrical structure wall cleaning equipment has a transfer function, and can buffer the impact received during the transfer process to avoid damage to the workpiece 10 caused by ground impact.

[0077] In some embodiments of the present application, the driving component 3, the lifting component 7 and the horizontal sliding component 6 are all connected to the controller, and automatic cleaning can be achieved through an automatic control system. The automatic control system is equipped with a monitoring sensor, which can issue an alarm in time when an abnormal situation occurs and can cause the equipment to stop urgently.

[0078] In some embodiments of this application, please refer to Figures 1 to 10 The method of using the above cylindrical structure wall cleaning equipment is as follows:

[0079] Step 1: Move the cylindrical structure wall cleaning equipment to the side of the single crystal furnace;

[0080] Step 2: Adjust the position of the protective cover 4 by using the lifting assembly 7 and the horizontal sliding assembly 6 so that the protective cover 4 is located on the side of the second workbench 52 away from the first workbench 51;

[0081] Step 3: Move the heater (and the workpiece 10) horizontally so that the bottom of the heater cartridge 101 is at a certain distance (about 1-3 cm) from the table surface of the workbench assembly 5 until the heater cartridge 101 is aligned with the first placement groove 511 and the second placement groove 521. Then, lower the heater so that the bottom of the heater cartridge 101 is embedded in the first placement groove 511 and the second placement groove 521.

[0082] Step 3: Make the bottom of the protective cover 4 higher than the top of the heater cylinder 101, and use the horizontal sliding assembly 6 to drive the lifting assembly 7 and the protective cover 4 to slide as a whole until the protective cover 4 is above the heater cylinder 101 and the slider 62 moves to the centering limit point;

[0083] Step 4: The lifting assembly 7 drives the protective cover 4 to descend, and the multiple brush assemblies 1 clamp the heater cylinder 101, wherein the multiple first brushes 11 contact the inner wall of the heater cylinder 101, and the multiple second brushes 12 contact the outer wall of the heater cylinder 101;

[0084] Step 5: Start the drive assembly 3, the brush holder assembly 2 drives the brush assembly 1 to rotate along the circumference of the heater cylinder 101, and at the same time, the transmission shaft 33 drives the first brush 11 to rotate, and the first brush 11 drives the second brush 12 to rotate through the first transmission assembly 13, thereby achieving all-round and fully automatic cleaning of the inner and outer walls of the heater cylinder 101;

[0085] Step 6: After cleaning, the lifting assembly 7 lifts the protective cover 4, and the horizontal sliding assembly 6 slides the protective cover 4 to an area that does not interfere with the workpiece 10, so that the heater can be unloaded.
