Description

Technical Field

[0001] The invention relates to the technical field of ceramic product grinding, in particular to a multi-angle grinding device and method for ceramic product processing. Background Art

[0002] The grinding equipment used in the processing of ceramic products is to make the surface of ceramic products reach the required smoothness, precision and beauty through methods such as grinding and polishing. The main frame of this type of equipment is usually made of steel or aluminum alloy to ensure stability and strength. The core component is the grinding head or abrasive tool, which is made of materials such as diamond and grinding wheel, and is driven by a motor to achieve rotational motion. The working principle is based on the contact friction between the grinding head and the ceramic surface. The surface roughness is removed by the set pressure to ensure the surface is flat. The control system adjusts the speed and pressure to ensure the processing quality. The coolant cools the grinding head and cleans the surface at the same time, improving the processing efficiency and product quality; such as a ceramic disc grinding equipment disclosed in the authorization announcement number CN112247783B, including a rotating base, a movable mounting seat, a polishing machine, a grinder, a rotating dust suction mechanism, and an automatic blanking mechanism. The ceramic disc is placed by an automatic material placement mechanism, and there is a suction cup on the rotating base, which fixes the ceramic disc. When the material rotates to the position of the grinder, the grinder starts to grind the ceramic disc, and the rotating dust suction mechanism starts to work to collect dust. However, in the use process of this technical scheme, the upper surface or the lower surface of the ceramic disc is mainly polished and polished by a polisher or grinder, and the ceramic disc itself also has an upwardly inclined annular rib, which also needs to be processed by a polisher or grinder. At this time, the polisher or grinder only operates on a single side of the annular rib. After polishing of this side, the staff needs to turn the ceramic disc over and repeat the above operation. Single-sided operation will result in a relatively long processing time for each ceramic disc, especially in mass production. Inefficiency will directly affect the overall production progress, and manual flipping of the ceramic disc may also lead to inconsistent processing. Even experienced operators find it difficult to ensure that the polishing quality of each ceramic disc after flipping is completely consistent. Summary of the invention

[0035] The pulley horizontal linear distance adjustment module 5 includes synchronous pulleys rotatably installed on both sides of the top of the circular opening base 1, two parallel guide pillars and a multi-V belt wrapped between the two synchronous wheels. A support platform is slidably installed on one end of the surface of the two guide pillars. The top of the support platform is fixedly connected to the bottom end of the sliding frame 3, and the bottom end of the support platform is fixedly connected to one end of the multi-V belt. A servo motor for driving one of the synchronous pulleys to rotate is also installed at the bottom end of the circular opening base 1. When the negative pressure rotating suction cup module 14 completes the adsorption and fixation of the ceramic disc workpiece, the staff starts the pulley horizontal linear distance adjustment module 5 through the PLC control panel 15 to work, and the pulley horizontal linear distance adjustment module 5 pulls the sliding frame 3 and the sloped multi-angle double-sided grinding module 6 to slide toward the upper suspended frame 2 until the bevel of the ceramic disc is located between the upper double-wheel grinding arm 8 and the lower single-wheel grinding arm 9, ensuring that the equipment adapts to the current ceramic disc specifications and processing requirements.

[0036] A multi-angle grinding method for ceramic product processing of this embodiment, such as the multi-angle grinding device for ceramic product processing described above, comprises the following steps:

[0037] S101: connecting the exhaust end of the negative pressure rotating suction cup module 14 to an external negative pressure pump, then placing the ceramic disc to be polished on the negative pressure rotating suction cup module 14, and fixing the ceramic disc by using the negative pressure rotating suction cup module 14 and the negative pressure pump;

[0038] S102; After the ceramic disc is fixed by the negative pressure rotating suction cup module 14, the staff adjusts the distance between the two adjacent slope-type multi-angle double-sided grinding modules 6 through the pulley horizontal linear distance adjustment module 5 according to the disc diameter of the ceramic disc, and uses the lifting mechanism 7 to drive the upper double-wheel grinding arm 8 to move downward, so that the grinding surface of the upper double-wheel grinding arm 8 contacts the upper surface of the circular bevel of the ceramic disc, and the debugging work of the lifting mechanism 7, the upper double-wheel grinding arm 8, and the lower single-wheel grinding arm 9 with the circular bevel of the ceramic disc is completed;

[0039] S103: The staff starts the sloped multi-angle double-sided grinding module 6 through the PLC control panel 15 to work, and the upper double-wheel grinding arm 8 and the lower single-wheel grinding arm 9 grind the upper surface and the lower surface of the circular bevel of the ceramic disc respectively until the upper double-wheel grinding arm 8 and the lower single-wheel grinding arm 9 cover all the areas that need to be processed;

[0040] S104: After the grinding process is completed, the equipment stops running and the operator unloads the processed ceramic disc.

[0041] Embodiment 2, based on embodiment 1, Figure 6 and Figure 7 It is given that the upper-mounted double-wheel grinding arm 8 includes a lower sliding arm 801 slidably mounted on the outer wall of one side of the right-angle plate 4, two first grinding wheels 802 rotatably mounted on the outer wall of one side of the lower sliding arm 801, and a pulley synchronous transmission structure 803 for maintaining power connection between the two first grinding wheels 802 and the double-headed universal shaft 12. A shaft seat 401 is fixed on the outer wall of one side of the right-angle plate 4, and one end of the double-headed universal shaft 12 is rotatably mounted inside the shaft seat 401 through a ball bearing;

[0042] The lifting mechanism 7 includes a double-rod cylinder 701 installed on the back of the right-angle plate 4 and a right-angle fork seat 702 installed on the top of the piston rod of the double-rod cylinder 701. The bottom end of the right-angle fork seat 702 is fixedly connected to the top of the lower sliding arm 801. The staff uses the PLC control panel 15 to start the double-rod cylinder 701 to work, and the double-rod cylinder 701 drives the right-angle fork seat 702, the lower sliding arm 801 and other components toward the upper surface of the bevel of the ceramic disk until the first grinding wheel 802 contacts the upper surface of the bevel of the ceramic disk, which allows the spacing between the upper and lower grinding arms to be adjusted to accommodate ceramic disks of different thicknesses;

[0043] The gear drive unit 10 includes a support plate 1001 installed at the bottom end of the sliding frame 3, a stepper motor 1002 installed on the outer wall of one side of the support plate 1001, and a three-gear transmission structure 1003 installed at the output end of the stepper motor 1002. A short transmission shaft 1004 is rotatably installed on the outer wall of the other side of the support plate 1001. The output end of the stepper motor 1002 drives the short transmission shaft 1004 to rotate through the three-gear transmission structure 1003. One end of the short transmission shaft 1004 maintains power connection with one end of the double-headed universal shaft 12 through a pulley synchronous transmission structure 13. Both ends of the double-headed universal shaft 12 are equipped with a cross universal coupling. Since both ends of the double-headed universal shaft 12 are equipped with a cross universal joint coupling, when the right-angle fork seat 702 drives the upper-mounted double-wheel grinding arm 8 to lift and slide, the double-headed universal shaft 12 can still be connected to the upper-mounted double-wheel grinding arm 8 and the pulley synchronous transmission structure 13 to maintain normal power transmission.

[0044] The lower transmission structure 11 includes a long transmission shaft 1101 rotatably mounted at the bottom end of the sliding frame 3 and a pulley synchronous transmission structure 3 1102 installed at one end of the long transmission shaft 1101 for driving the lower single-wheel grinding arm 9 to work. The other end of the long transmission shaft 1101 maintains power connection with the stepper motor 1002 through a three-gear transmission structure 1003. The lower single-wheel grinding arm 9 includes a lower hollow oblique arm 901 fixed obliquely upward at the top of the sliding frame 3 and a second grinding wheel 902 rotatably mounted at the top of the lower hollow oblique arm 901. The central axis of the second grinding wheel 902 is connected to the long transmission shaft 11 through the pulley synchronous transmission structure 3 1102. 01 for power transmission, the stepper motor 1002 in the gear drive unit 10 is turned on through the PLC control panel 15 to work, and the stepper motor 1002 drives the long transmission shaft 1101 and the short transmission shaft 1004 to rotate through the three-gear transmission structure 1003, and then the long transmission shaft 1101 drives the second grinding wheel 902 at the top of the lower hollow inclined arm 901 to rotate, and the short transmission shaft 1004 drives the double-headed universal shaft 12 to rotate through the pulley synchronous transmission structure 13, thereby realizing the synchronous movement of the upper and lower grinding arms, ensuring the stable rotation of each grinding wheel, and being able to effectively perform the polishing operation;

[0045] One end of the double-headed universal shaft 12 away from the pulley synchronous transmission structure 1 13 drives the two first grinding wheels 802 to rotate together through the pulley synchronous transmission structure 2 803, so that the first grinding wheels 802 perform grinding processing.

[0046] Embodiment 3, based on embodiment 2, Figure 8It is given that the negative pressure rotary suction cup module 14 includes a rotary joint 1403 fixed at the bottom end of the circular opening base 1, an exhaust pipe 1404 fixed at the top of the rotary joint 1403, and a hollow negative pressure plate 1405 with a through hole installed on the exhaust pipe 1404. A reduction motor 1401 is installed on one side of the bottom end of the circular opening base 1, and a pulley synchronous transmission structure 1402 for driving the exhaust pipe 1404 to work is installed at the output end of the reduction motor 1401. The bottom end of the rotary joint 1403 is connected to the negative pressure pump through a hose. When the negative pressure pump is pumping air, the hollow negative pressure plate 1405 is in a negative pressure state, thereby stably adsorbing the ceramic plate; by turning on the reduction motor 1401, the exhaust pipe 1404 is driven to rotate by the reduction motor 1401 and the pulley synchronous transmission structure 1402. During this process, the rotary joint 1403 keeps the exhaust pipe 1404 in a state of relative rotation connection with the external pipeline to ensure smooth air passage.

[0047] When the embodiment of the present application is in use, the staff first connects the exhaust end of the negative pressure rotating suction cup module 14 to an external negative pressure pump, and then places the ceramic disc to be polished on the negative pressure rotating suction cup module 14, and uses the negative pressure rotating suction cup module 14 and the negative pressure pump to fix the ceramic disc. The negative pressure rotating suction cup module 14 stably absorbs and rotates the ceramic disc by creating a negative pressure environment, which eliminates the need for manual flipping and fixing of the workpiece, and ensures the stability and safety of the ceramic disc during the rotation process, and enables the sloped multi-angle double-sided grinding module 6 to continuously process the upper and lower disc surfaces of the annular bevel of the ceramic disc. After the ceramic disc is fixed by the negative pressure rotating suction cup module 14, the staff The distance between two adjacent sloped multi-angle double-sided grinding modules 6 is adjusted by the diameter, that is, the staff turns on the pulley horizontal linear distance adjustment module 5 through the PLC control panel 15 to work, and the pulley horizontal linear distance adjustment module 5 drives the sliding frame 3 and one of the sloped multi-angle double-sided grinding modules 6 to move toward the upper suspended frame 2 until the annular bevel of the ceramic disc is located between the upper double-wheel grinding arm 8 and the lower single-wheel grinding arm 9, and the grinding surface of the lower single-wheel grinding arm 9 is in contact with the lower surface of the annular bevel of the ceramic disc, and the lifting mechanism 7 is used to drive the upper double-wheel grinding arm 8 to move downward, so that the grinding surface of the upper double-wheel grinding arm 8 is in contact with the upper surface of the annular bevel of the ceramic disc, thereby completing the lifting mechanism 7 and the upper double-wheel grinding. The staff starts the gear drive unit 10 in the slope-type multi-angle double-sided grinding module 6 through the PLC control panel 15 to work, and the rotary power of the gear drive unit 10 is transmitted to the lower transmission structure 11 and the pulley synchronous transmission structure 13 respectively. The pulley synchronous transmission structure 13 uses the double-headed universal shaft 12 to drive the upper double-wheel grinding arm 8 to work, and the lower transmission structure 11 drives the lower single-wheel grinding arm 9 to work. The double-headed universal shaft 12 can keep itself in a power connection state with the pulley synchronous transmission structure 13 during the up and down sliding process of the upper double-wheel grinding arm 8, that is, the upper double-wheel grinding arm 8 and the lower single-wheel grinding arm 9 are connected. Driven by the gear drive unit 10, the grinding operation is carried out together. The operator starts the negative pressure rotating suction cup module 14 through the PLC control panel to stabilize the adsorption disk surface and make the ceramic disk start to rotate. The upper double-wheel grinding arm 8 and the lower single-wheel grinding arm 9 respectively grind the upper and lower surfaces of the annular bevel of the ceramic disk until the upper double-wheel grinding arm 8 and the lower single-wheel grinding arm 9 cover all areas that need to be processed. During this process, the staff can control the rotation speed of the negative pressure rotating suction cup module 14 and the gear drive unit 10 through the PLC control panel 15 to optimize the processing effect. After the grinding program is completed, the equipment stops running, the operator unloads the processed ceramic disk, and performs necessary inspection and cleaning.
