Description

Technical Field

[0001] This utility model relates to the technical field of stone polishing equipment, and in particular to a surface thickness-fixing polishing equipment for basins. Background Technology

[0002] As a sanitary ware used in daily life, washbasins are commonly made of stone, ceramic, and resin. After the washbasin is formed, its surface needs to be polished, especially the basin surface, which requires high flatness, smoothness, and user comfort. The polishing process is divided into two steps: roughing and finishing. During roughing, the unevenness of the basin surface is first smoothed and the thickness is fixed, providing a foundation for the subsequent finishing process and saving workload and energy consumption.

[0003] In the prior art, polishing equipment is usually used to polish the surface of the washbasin. For example, Chinese invention patent CN109648438B, entitled "Automatic Polishing Equipment for Washbasins", includes a first conveyor line, a second conveyor line, a side polishing device, and a curved surface polishing device. The first and second conveyor lines are each provided with a lifting and positioning device for lifting and locking the washbasin. The side polishing device is used to polish the side of the washbasin on the lifting and positioning device in the first conveyor line, and the curved surface polishing device is used to polish the water basin of the washbasin on the lifting and positioning device in the second conveyor line.

[0004] However, the existing technology still has the following drawbacks:

[0005] 1. Existing grinding equipment typically uses robotic arms as the grinding and polishing devices on the conveyor line. The polishing components are located at the moving end of the robotic arm. Although the robotic arm can polish flexibly at multiple angles, its arm is relatively long and is prone to shaking during movement. This is especially true when grinding to a fixed thickness along a circular trajectory on the basin surface. It is difficult for the robotic arm to maintain the grinding accuracy of the basin surface during repeated horizontal and vertical movements and vertical lifting. Moreover, the manufacturing and maintenance costs of the robotic arm are relatively high.

[0006] 2. The existing basin conveyor line needs to be equipped with a lifting and positioning device to lift and lock the washbasins in order to cooperate with the polishing work of the robotic arm. The lifting and locking process of the lifting and positioning device takes up a lot of time in the polishing of the washbasins, reducing the polishing efficiency. Moreover, the installation of the lifting and positioning device on the basin conveyor line also increases the production and manufacturing cost of the polishing equipment. Utility Model Content

[0007] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a surface thickness grinding device for basins.

[0008] The purpose of this utility model is achieved by the following technical solution: a surface thickness grinding device for a basin, including a frame, side frames are provided on the left and right sides of the frame, and a base frame for placing the basin is provided between the side frames on the left and right sides.

[0009] The side frame is provided with a longitudinal beam, the longitudinal beam is provided with a longitudinal conveying component and carries several cross beams through the longitudinal conveying component, the cross beam is provided with a transverse conveying component and carries a lifting assembly and a grinding head assembly for grinding and processing basins through the transverse conveying component.

[0010] The lifting assembly has a lifting driver and a lifting guide. The grinding head assembly is movably mounted on the lifting guide and connected to the output end of the lifting driver, so that the grinding head assembly slides along the annular surface of the basin under the conveying control of the longitudinal conveying component and the transverse conveying component, and descends along the lifting guide under the control of the lifting driver to perform fixed-thickness grinding on the basin surface.

[0011] Furthermore, the lifting assembly also includes a lifting base, which is disposed on the transverse conveying component. The lifting guide includes a lifting slide rail and a lifting screw, which is arranged between two lifting slide rails and parallel to each other on the lifting base. The grinding head assembly is movably disposed on the lifting slide rail. One end of the lifting screw is connected to the output end of the lifting driver, and the other end of the lifting screw is fixedly connected to the grinding head assembly.

[0012] Furthermore, the lifting assembly and the grinding head assembly are symmetrically arranged on both sides of the transverse conveying component. The grinding head assembly has a grinding head, and the transverse conveying component controls the grinding heads of the grinding head assemblies on both sides to grind the basin surfaces at both ends of the basin.

[0013] Furthermore, the grinding heads of the grinding head assemblies symmetrically arranged on both sides of the transverse conveying component are positioned on the same longitudinal grinding line, and the longitudinal conveying component controls the grinding heads on the same longitudinal grinding line to grind the same side surface of the basin.

[0014] Furthermore, the grinding head assembly also includes a grinding motor and a protective shell. The output end of the grinding motor is connected to the grinding head for transmission, and the protective shell covers the grinding motor and the grinding head.

[0015] Furthermore, the base frame is provided with several rows of conveyor frames extending along the length of the longitudinal beam and used to carry the basins to be polished, so that the grinding head assembly can be polished along the annular surface of the basin under the conveying control of the longitudinal conveying component and the transverse conveying component.

[0016] Furthermore, the conveyor frame has a support portion for supporting the left and right sides of the basin, and a basin conveying component for conveying the basin is provided on the support portion. There is a receiving area for accommodating the bottom of the basin between the support portions on the left and right sides of the conveyor frame.

[0017] Furthermore, the longitudinal conveying component includes a longitudinal slide rail, a longitudinal rack, and a longitudinal conveying motor. Two longitudinal slide rails are provided, and the longitudinal rack is arranged between the two longitudinal slide rails and parallel to each other. The two ends of the crossbeam and the longitudinal conveying motor are mounted on the longitudinal slide rails through longitudinal slide blocks, and the output end of the longitudinal conveying motor meshes with the longitudinal rack through a longitudinal gear, so that the longitudinal conveying motor drives the longitudinal slide block and the crossbeam mounted thereon to slide back and forth along the longitudinal slide rail direction.

[0018] Furthermore, the longitudinal conveying motors on the side longitudinal beams of the frame are electrically servo synchronously connected via synchronous shafts.

[0019] Furthermore, the transverse conveying component includes a transverse slide rail, a transverse rack, and a transverse conveying motor. Two transverse slide rails are provided, and the transverse rack is arranged between the two transverse slide rails and parallel to each other. The transverse conveying motor and the grinding head assembly are mounted on the transverse slide rails via a transverse slide block, and the output end of the transverse conveying motor meshes with the transverse rack via a gear, so that the transverse conveying motor drives the transverse slide block and the mounted grinding head assembly to reciprocate along the transverse slide rail direction.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] (1) The present application provides a method to set a lifting component on a horizontal conveying component and a grinding head component on a lifting guide of the lifting component, so that the grinding head component can move up and down along the direction of the lifting guide under the drive control of the lifting driver, thereby controlling the thickness grinding accuracy of the grinding head component in the vertical direction, realizing the automated and precise control of the thickness grinding of the grinding head component, with a high degree of automation, saving labor costs and improving work efficiency.

[0022] Furthermore, with the coordinated conveying control of the longitudinal and transverse conveying components, the grinding head assembly can perform grinding processing on the same side and both ends of the washbasin in the longitudinal and transverse directions. Compared with the previous grinding equipment that used multiple robotic arms on the conveyor line to grind and polish the washbasin, the embodiments of this application provide more stable control over the longitudinal, transverse and vertical movements of the grinding head assembly, so as to achieve higher precision in the thickness grinding of the washbasin surface and lower manufacturing cost of the robotic arms compared with the previous grinding equipment.

[0023] (2) By starting the lifting drive of the lifting assembly, the lifting screw is controlled to rotate, and the lifting screw drives the motor base to rise and fall along the vertical direction of the lifting guide, thereby controlling the lowering set height of the motor base and the grinding head, and then adjusting the grinding head to perform fixed thickness grinding on the basin surface, so as to realize the automated fixed thickness grinding of the basin surface; moreover, by arranging the lifting screw between two lifting slide rails, the lifting driving force of the lifting screw on the motor base is relatively concentrated between the two lifting slide rails, and the motor base is guided to rise and fall by the two lifting slide rails, thereby improving the stability of the lifting action of the motor base, the grinding motor and the grinding head, and thus improving the fixed thickness grinding accuracy of the grinding head on the basin surface.

[0024] (3) By setting a support and a receiving area on the conveyor frame, the edge of the washbasin is flush with the support and the bottom of the washbasin is stored in the receiving area of ​​the conveyor frame. In this way, the support and receiving area of ​​the conveyor frame are reasonably installed according to the shape characteristics of the washbasin, ensuring that only the left and right edges of the washbasin exert gravity on the support, so that the gravity of the washbasin is relatively concentrated, further improving the stability of the washbasin installation and avoiding shaking. The support supports the edge of the washbasin, which can meet the bearing capacity of the grinding head assembly when grinding the annular surface of the washbasin.

[0025] (4) By setting a washbasin conveying component on the support of the conveyor frame, the washbasin is carried by the washbasin and conveyed from the front end to the end of the conveyor frame, so that several washbasins can flow and be polished on the conveyor frame through the washbasin conveying component, thereby achieving the purpose of assembly line-style washbasin polishing and improving the polishing efficiency of washbasins.

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0042] like Figure 1-7 As shown, a surface thickness grinding device for basins is used to grind the unevenness of the basin surface P1 of a hand basin P made of stone, ceramic and resin materials, especially in the rough polishing process of the hand basin P, to improve the gloss and smoothness of the basin surface P1 of the hand basin P.

[0043] The surface thickness grinding equipment for this basin includes a frame 10, which has an overall shape that is roughly a U-shaped hollow structure. Therefore, vertically arranged side frames 101 are provided on both the left and right sides of the frame 10, and the distance between the side frames 101 on the left and right sides can reach 1600mm. The base frame 102 of the frame 10 is set between the two side frames 101 on the left and right sides.

[0044] The left and right side frames 101 of the frame 10 are provided with longitudinal beams 20. The length arrangement direction of the side frames 101 is also the extension direction of the longitudinal beams 20. The extension direction of the longitudinal beams 20 can be understood as the Y-axis direction.

[0045] A longitudinal conveying component 21 is provided on the longitudinal beam 20. The longitudinal conveying component 21 includes at least a longitudinal slide rail 211, a longitudinal rack 212, and a longitudinal conveying motor 213. When installing the longitudinal conveying component 21, two longitudinal slide rails 211 are provided, and the longitudinal rack 212 is provided between the two longitudinal slide rails 211. The longitudinal slide rails 211 and the longitudinal rack 212 are arranged parallel to each other and both extend along the length direction of the longitudinal beam 20. The stroke of the longitudinal slide rail 211 can reach 5000mm.

[0046] Longitudinal slide blocks 214 are installed on the two longitudinal slide rails 211. The longitudinal slide blocks 214 are used to support the two ends of the crossbeam 30 and the longitudinal conveyor motor 213. Therefore, the crossbeam 30 is mounted on the longitudinal beams 20 on the left and right sides of the frame 10. Moreover, the crossbeam 30 is arranged perpendicular to the longitudinal direction. The extension direction of the crossbeam 30 can be understood as the X-axis direction.

[0047] The longitudinal conveying motor 213 provided in this embodiment of the application is provided with a longitudinal gear 2131 at its output end, and the longitudinal gear 2131 meshes with the longitudinal rack 212. Since the longitudinal conveying motor 213 is fixedly connected to the longitudinal slide block 214, by starting the longitudinal conveying motor 213 and making its output end's longitudinal gear 2131 mesh with the rack, the longitudinal slide block 214 slides back and forth along the longitudinal slide rail 211, and the entire crossbeam 30 also slides back and forth on the longitudinal slide rail 211 along with the longitudinal slide block 214.

[0048] In practical applications, the longitudinal conveying motor 213 adopts a servo motor and is equipped with a reducer. The reducers of the longitudinal conveying motors 213 on the left and right sides of the frame 10 are also equipped with couplings, and a synchronous shaft 215 is connected through the couplings. This enables the longitudinal conveying motors 213 on the left and right sides of the frame 10 to achieve electric servo synchronous connection, ensuring synchronous sliding on the longitudinal slide rail 211, and improving the polishing quality and efficiency of the washbasin P.

[0049] According to the actual grinding and processing needs, several crossbeams 30 can be installed on the longitudinal beam 20 via the longitudinal conveying component 21. A transverse conveying component 31 is provided on each crossbeam 30. This transverse conveying component 31 includes at least a transverse slide rail 311, a transverse rack 312, and a transverse conveying motor 313. When installing the transverse conveying component 31, two transverse slide rails 311 are provided, and the transverse rack 312 is positioned between the two transverse slide rails 311. The transverse slide rails 311 and the transverse rack 312 are arranged parallel to each other and extend along the length of the crossbeam 30. The stroke length of the crossbeam 30 is approximately the same as the width between the longitudinal beams 20 on the left and right sides of the frame 10. A transverse slide block 314 is installed on each of the two transverse slide rails 311. This transverse slide block 314 is used to support the transverse conveying motor 313 and the grinding head assembly 40 for grinding the washbasin P.

[0050] Similar to the longitudinal conveying component 21, the output end of the transverse conveying motor 313 provided in this embodiment of the application is provided with a gear, which meshes with the transverse rack 312. Since the transverse conveying motor 313 is fixedly connected to the transverse slide 314, by starting the transverse conveying motor 313 and meshing the gear and rack at its output end, the transverse slide 314 slides back and forth along the transverse slide rail 311, and the grinding head assembly 40 also slides back and forth on the transverse slide rail 311 along with the transverse slide 314.

[0051] Therefore, through the optimized design of the longitudinal beams 20 and transverse beams 30 on the frame 10, the longitudinal conveyor motor 213 and the transverse conveyor motor 313, under the control of PLC program instructions, can automatically drive the grinding head assembly 40 to slide in the X and Y axis directions and polish the annular basin surface P1 of the washbasin P. Compared with the previous implementation method that could only polish the washbasin P at a fixed position, this application implements a controllable grinding head assembly 40 that performs automated grinding processing according to the annular basin surface P1 of the washbasin P, which has a high degree of automation, high grinding efficiency, and saves labor intensity.

[0052] Regarding the optimized design of the support and conveying of the washbasin P, several rows of conveyor frames 50 are provided on the base frame 102. In this embodiment, at least two rows of conveyor frames 50 are provided. The two rows of conveyor frames 50 are arranged in parallel and extend along the length of the longitudinal beam 20. The conveyor frames 50 are used to support and convey the washbasin P to be polished. Several washbasins P can be placed simultaneously along the length of the conveyor frames 50. According to the size design of the frame 10 and the conveyor frames 50, each row of conveyor frames 50 in this embodiment can hold at least one washbasin P, and the two rows of conveyor frames 50 can hold a total of one washbasin P. Of course, the polished washbasin P is also conveyed to the subsequent finishing process via the conveyor frames 50.

[0053] The conveyor frame 50 provided in this embodiment has support portions 501 on its left and right sides, and the support portions 501 on the left and right sides of the conveyor frame 50 are spaced apart to form a receiving area 502. When the washbasin P is installed on the conveyor frame 50, the longer left and right sides of the washbasin P can be installed flat on the support portions 501 of the conveyor frame 50, and the downward protruding bottom of the washbasin P can be accommodated in the receiving area 502. In this way, the support portions 501 and the receiving area 502 of the conveyor frame 50 are used to reasonably install the washbasin P according to its shape characteristics.

[0054] In addition, a washbasin P conveying component (not shown in the figure) is provided on the support part 501 of the conveyor frame 50. The washbasin P is carried by the washbasin P. The washbasin P conveying component can be configured as a slide rail slider, belt, roller or slide bar slide. The front end of the conveyor frame 50 serves as the loading end of the washbasin P to be polished, and the end of the conveyor frame 50 serves as the unloading end of the washbasin P after polishing. In this way, the washbasin P is conveyed from the front end to the end of the conveyor frame 50 by the washbasin P conveying component.

[0055] Therefore, by ensuring that the edge of the washbasin P fits flat against the support 501, a horizontal installation environment is provided for the washbasin P, allowing it to be installed flat and stably on the conveyor frame 50. This ensures the uniformity of the grinding thickness of the washbasin P surface P1 by the grinding head assembly 40, improving the gloss and smoothness of the grinding. Furthermore, by housing the bottom of the washbasin P in the receiving area 502 of the conveyor frame 50, it is ensured that only the left and right edges of the washbasin P exert gravity on the support 501, making the gravity of the washbasin P relatively concentrated. This further improves the stability of the washbasin P installation and prevents shaking. Thus, by supporting the edge of the washbasin P with the conveyor frame 50, the bearing capacity of the grinding head assembly 40 during the grinding of the annular surface P1 of the washbasin P can be met.

[0056] Compared to previous grinding equipment that used lifting and positioning devices on the conveyor line to lift and lock the washbasin P, this embodiment allows the washbasin P to be directly installed on the support 501 and the receiving area 502 of the conveyor frame 50, eliminating the need for additional lifting and locking components. This reduces the manufacturing cost of the conveyor line, eliminates the tedious operation of repeatedly lifting and locking the washbasin P, and allows several washbasins P to be placed on the conveyor frame 50. These washbasins P flow and are ground on the conveyor frame 50 via the washbasin P conveying components, achieving a streamlined grinding process for the washbasins P and improving the grinding efficiency of the washbasins P.

[0057] The transverse conveying component 31 of the beam 30 provided in this embodiment carries a lifting assembly 60 and a grinding head assembly 40 for grinding the washbasin P. The lifting assembly 60 has a lifting base 603, a lifting driver 601, and a lifting guide 602. The lifting guide 602 includes a lifting slide rail 6021 and a lifting lead screw 6022. The lifting driver 601 can be a servo motor. The grinding head assembly 40 has a grinding head 401, a grinding motor 402, a protective shell 403, and a motor base 404.

[0058] Vertically arranged lifting bases 603 are symmetrically installed on both sides of the transverse slide 314 of the transverse conveying component 31. The grinding head assembly 40 is movably installed on the lifting base 603 through the lifting guide 602, and performs lifting and lowering actions under the control of the lifting driver 601. When the grinding head assembly 40 descends, it performs fixed-thickness grinding on the basin surface P1 of the washbasin P.

[0059] Therefore, based on the optimized design of symmetrically arranging the grinding head assemblies 40 on both sides of the transverse slide 314, when the transverse conveyor motor 313 drives the transverse slide 314 and moves the grinding head assemblies 40 on both sides of it to slide above both ends of the washbasin P, the grinding heads 401 of the two grinding head assemblies 40 can respectively correspond to the basin surfaces P1 at both ends of the washbasin P. Under the drive control of the transverse conveyor motor 313, the grinding heads 401 of the grinding head assemblies 40 on both sides of the transverse slide 314 can synchronously grind the basin surfaces P1 at both ends of the washbasin P on the conveyor frame 50, thereby improving the efficiency of the grinding head assemblies 40 in grinding the basin surfaces P1 at both ends of the washbasin P to a fixed thickness.

[0060] Furthermore, the grinding heads 401 of the symmetrically arranged grinding head assemblies 40 on both sides of the transverse slide 314 are positioned on the same longitudinal grinding line. This allows the longitudinal conveying motor 213 to drive the longitudinal slide 214 and the crossbeam 30 to slide longitudinally, causing the grinding head assemblies 40 on the transverse slide 314 to slide above the left / right side of the washbasin P. At this point, the grinding heads 401 of the two grinding head assemblies 40 can respectively correspond to the same side of the washbasin P's basin surface P1. Under the drive control of the longitudinal conveying motor 213, the grinding heads 401 of the grinding head assemblies 40 on both sides of the transverse slide 314 synchronously grind the same side of the washbasin P's basin surface P1 on the conveyor frame 50 along the same longitudinal line, improving the efficiency of the grinding head assemblies 40 in grinding the basin surfaces P1 of both sides of the washbasin P to a fixed thickness.

[0061] Compared to previous polishing equipment that uses multiple robotic arms on a conveyor line to polish the washbasin P, the grinding head assembly 40 provided in this embodiment can slide along the same side surface P1 and both ends surface P1 of the washbasin P under the conveying control of the longitudinal conveying component 21 and the transverse conveying component 31, respectively. It can also descend along the lifting guide 602 under the control of the lifting driver 601 to perform precise thickness grinding on the surface P1. This method has a high degree of automation, saves labor costs, improves work efficiency, enhances the stability of the grinding head assembly 40 in the longitudinal, transverse and vertical directions, improves the thickness grinding accuracy of the grinding head assembly 40 on the surface P1 of the washbasin P, and reduces manufacturing costs.

[0062] More specifically, the lifting screw 6022 is arranged between two lifting slide rails 6021 and is parallel to each other on the lifting base 603. The lifting screw 6022 and the lifting slide rails 6021 are arranged vertically on the lifting base 603. The motor base 404 is movably mounted on the two lifting slide rails 6021 of the lifting assembly 60 via a slider. The grinding motor 402 is fixedly mounted on the motor base 404, and the grinding head 401 is drivenly connected to the output end of the grinding motor 402.

[0063] The upper end of the lifting screw 6022 is connected to the output end of the lifting driver 601, and the lower end of the lifting screw 6022 is fixedly connected to the motor base 404. Therefore, by starting the lifting driver 601, the lifting screw 6022 is controlled to rotate, and the lifting screw 6022 drives the motor base 404 to rise and fall along the vertical direction of the lifting guide 602. By controlling the set height of the descent of the motor base 404 and the grinding head 401 mounted on it, the grinding head 401 is adjusted to perform fixed-thickness grinding on the basin surface P1, thereby realizing the automated fixed-thickness grinding of the basin surface P1 of the washbasin P.

[0064] Furthermore, by arranging the lifting screw 6022 between the two lifting slide rails 6021, the lifting driving force of the lifting screw 6022 on the motor base 404 is relatively concentrated between the two lifting slide rails 6021. The motor base 404 is guided to rise and fall by the two lifting slide rails 6021, which further improves the stability of the lifting action of the motor base 404, the grinding motor 402 and the grinding head 401, and further improves the grinding head 401's precision in grinding the surface P1 at a fixed thickness.

[0065] The protective housing 403 includes a motor cover and a side sealing plate. The motor cover is used to cover the outside of the grinding motor 402 and protect the grinding motor 402. The side sealing plate covers the splash-proof side of the grinding head 401 to prevent grinding debris and water from splashing out during the grinding process.

[0066] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
