DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0029] Please see attached Figure 1 -Attached Figure 8 The embodiment of the present invention provides a splicing and repair auxiliary equipment for ceramic archaeology, including an installation base plate 1, the top four corners of the installation base plate 1 are fixedly connected to a support frame 2, an electric turntable 601 is installed on the outer side of the installation base plate 1, a first swing arm 602 is installed on the outer side of the electric turntable 601, the end of the first swing arm 602 is movably connected to the second swing arm 603 through a bearing, an electric suction cup 604 is rotatably installed on the end of the second swing arm 603, a first electric telescopic rod 605 is installed on the outer side of the second swing arm 603, a second electric telescopic rod 606 is installed on the outer side of the first swing arm 602, the output end of the second electric telescopic rod 606 is rotatably connected to the outer side of the second swing arm 603, the output end of the first electric telescopic rod 605 is rotatably connected to the outer side of the electric suction cup 604, and a drying component is installed at the bottom of the installation base plate 1.
[0030] Specifically, first, a first swing arm 602 is installed on the outside of the device, and the swing arm is driven by the electric turntable 601 to rotate. The rotation of the electric turntable 601 drives the rotation of the first swing arm 602, thereby providing the required motion trajectory and control for the subsequent swing arm. The end of the first swing arm 602 is movably connected to the second swing arm 603 through a bearing. The bearing connection provides good mobility and stability, so that the second swing arm 603 can rotate or swing within a certain range as needed, which is convenient for carrying fragments. The end of the second swing arm 603 is rotatably installed with an electric suction cup 604, which firmly adsorbs the ceramic fragments on its surface through suction. The installation design of the electric suction cup 604 ensures the flexibility and efficiency of the adsorption operation, so that the equipment can accurately grasp the ceramic fragments during splicing and avoid errors in manual operation. The movement of the electric suction cup 604 is controlled by the second electric telescopic rod 606 and the first electric telescopic rod 605. Specifically, the second electric telescopic rod 606 is installed on the outside of the second swing arm 603, and its output end drives the second swing arm 603 to swing up and down through telescopic action, thereby adjusting the position of the electric suction cup 604 so that it can accurately align with the ceramic fragments and adsorb them.
[0031] At the same time, the output end of the first electric telescopic rod 605 is rotatably connected to the outer side of the electric suction cup 604, further realizing the precise control of the electric suction cup 604, and adjusting the angle and position of the suction cup as needed to ensure that it can grab the ceramic fragments inside the placement box 5. In this way, the electric suction cup 604 can be operated at different splicing positions, so that the ceramic fragments can be accurately transported and spliced.
[0032] Precise control of the entire operation process is achieved through the coordinated action of the above-mentioned components: the electric turntable 601 drives the first swing arm 602 to rotate, the first and second electric telescopic rods 606 jointly control the up and down movement of the swing arm, and the electric suction cup 604 is responsible for adsorbing the ceramic fragments and moving them accurately to the target position, ultimately achieving the splicing and repair of the ceramic fragments.
[0033] A dual-axis motor 807 is installed on the outer side of the installation base plate 1, and a transmission rod 806 is installed on one of the output ends of the dual-axis motor 807. One end of the transmission rod 806 is fixedly connected to a driving disk 801, and a fixed column 805 is fixedly connected to the outer eccentric part of the driving disk 801. Two limit disks 802 are fixedly connected to the bottom of the installation base plate 1, and a movable frame 804 is slidably connected to the outer side of the driving disk 801. The middle part of the outer side of the movable frame 804 is fixedly connected to the driving rod 803. A groove is provided inside the movable frame 804, and the fixed column 805 is movably connected inside the groove.
[0034] Specifically, the dual-axis motor 807 is an electric motor with two output shafts, which can provide bidirectional drive. By starting the motor, the rotation of the transmission rod 806 is achieved. The role of the motor is to provide a power source to provide motion driving force for the subsequent transmission system.
[0035] The function of the limit plate 802 is to control the range of motion of the movable frame 804, ensuring that it moves within a reasonable range and avoiding damage to the equipment caused by excessive movement. The drive rod 803 is installed in the middle of the outer side of the movable frame 804 and plays a connecting and driving role. By connecting with the movable frame 804, the drive rod 803 ensures that the movable frame 804 can move stably during operation.
[0036] When the device is started, the dual-axis motor 807 drives the transmission rod 806 to rotate through its output shaft, and the rotation of the transmission rod 806 drives the driving disk 801 to rotate coaxially. In this way, the fixed column 805 moves eccentrically with the rotation of the driving disk 801. The fixed column 805 slides freely in the groove inside the movable frame 804, driving the movable frame 804 to move along a specific trajectory. As the fixed column 805 slides along the groove, the movable frame 804 reciprocates on the inner wall of the limiting disk 802.
[0037] The drying assembly includes a fixed box 404 fixedly connected to the bottom of the installation base plate 1, a rubber piston 407 is slidably connected inside the fixed box 404, a movable column 406 is fixedly connected to the outside of the rubber piston 407, an air intake pipe 405 and a second connecting pipe 403 are sequentially connected to the outside of the fixed box 404, one end of the second connecting pipe 403 is fixedly connected to the heating device 401, the outside of the heating device 401 is connected to the first connecting pipe 402, and the first connecting pipe 402 is installed at the end of the second swing arm 603. Check valves are installed inside the second connecting pipe 403 and the air intake pipe 405, and the conduction directions of the two check valves are opposite.
[0038] Specifically, the rubber piston 407 is located inside the fixed box 404 and is slidably connected to the inside of the fixed box 404. Its function is to move the air by sliding and produce pressure changes. The movement of the rubber piston 407 will push the movable column 406, so that the gas inside the fixed box 404 flows, thereby realizing the discharge of the gas. The elasticity of the rubber piston 407 enables the system to accurately control the flow of gas. The heating device 401 is installed at one end of the second connecting pipe 403, and its main function is to heat the gas into hot air. The heating device 401 is equipped with a heating wire inside. When the gas passes through the heating device 401, the heating wire heats the gas, so that the gas temperature increases and forms hot air. The flow of hot air helps to quickly dry the joints of the ceramic fragments.
[0039] The main function of the first connecting pipe 402 connecting the heating device 401 and the second swing arm 603 is to discharge the heated hot air from the heating device 401. The hot air is guided to the area to be dried through the first connecting pipe 402, and is finally used to quickly dry the connection of the ceramic fragments.
[0040] One-way valves are installed inside the air inlet pipe 405 and the second connecting pipe 403, and the two one-way valves are in opposite directions. This design ensures that the flow direction of the gas inside the fixed box 404 is controlled. When the gas enters from the outside, the one-way valve can prevent the gas from flowing back; similarly, when the gas is discharged, the one-way valve ensures that the gas flow can flow smoothly to the heating device 401 to avoid unnecessary reverse flow.
[0041] When the movable frame 804 reciprocates along the inner wall of the limit plate 802 driven by the fixed column 805, the movable column 406 will move synchronously, pushing the rubber piston 407 to slide inside the fixed box 404. When the rubber piston 407 moves in a direction away from the movable column 406, the gas inside the fixed box 404 will be discharged into the heating device 401 through the second connecting pipe 403. The realization of this process depends on the pressure change of the gas in the fixed box 404. The gas entering the heating device 401 is heated by the electric heating wire to form hot air with a higher temperature. The design of the heating device 401 ensures that the gas can be effectively heated and generate enough heat for drying. The heated hot air is discharged through the first connecting pipe 402 and transported to the connection of the ceramic fragments through the end side of the second swing arm 603. The rapid flow of hot air can effectively accelerate the drying process of the connection of the ceramic fragments and shorten the repair time. The one-way valve in the air inlet pipe 405 and the second connecting pipe 403 plays a role in controlling the direction of the air flow. The one-way valve of the air inlet pipe 405 allows air to enter the fixed box 404, while the one-way valve of the second connecting pipe 403 ensures that there is no reverse flow when the gas flows to the heating device 401.
[0042] It also includes a driving gear 9, which is fixedly connected to the other output end of the dual-axis motor 807. The top of the mounting base 1 is rotatably connected to a placement plate 7, and the outer side of the placement plate 7 is fixedly connected to a gear ring 10. The outer side of the driving gear 9 is meshed with the outer side of the gear ring 10.
[0043] Specifically, by starting the other output end of the dual-axis motor 807, the driving gear 9 is driven to rotate coaxially, which in turn drives the gear ring 10 to rotate, and further drives the placement plate 7 to rotate synchronously, making it convenient for the staff to repair the ceramics.
[0044] The top of the support frame 2 is fixedly connected with a storage box 301, the top of the storage box 301 is installed with a pump body 302, the output end of the pump body 302 is fixedly connected with a second connecting pipe 304, and the input end of the pump body 302 is fixedly connected with a first connecting pipe 303. One end of the first connecting pipe 303 is connected to the inside of the storage box 301, and one end of the second connecting pipe 304 is installed on the outside of the second swing arm 603.
[0045] Specifically, storage box 301: Storage box 301 is located on the top of support frame 2, and its main function is to store adhesive or other repair materials for repairing ceramic fragments. The design of storage box 301 ensures that the adhesive can be stored safely and stably to avoid leakage or contamination. Pump body 302 is installed on the top of storage box 301, and its main function is to extract the adhesive in storage box 301 and transport it to the connection of ceramic fragments through the pipeline system. The start and stop of pump body 302 controls the flow rate and delivery speed of adhesive, thereby ensuring that adhesive is supplied on demand during the repair process.
[0046] When the ceramic fragments need to be repaired, the work is started by starting the pump body 302. As the core component of liquid transportation, the pump body 302 will suck the adhesive in the storage box 301 and transport it to the repair position through the pipeline system. The input end of the pump body 302 guides the adhesive in the storage box 301 to the inside of the pump body 302 through the first connecting pipe 303. The first connecting pipe 303 ensures that the flow channel of the adhesive from the storage box 301 to the pump body 302 is unobstructed. It is sent to the outside of the second swing arm 603 through the second connecting pipe 304. The pipeline system enables the adhesive to be accurately discharged to the joint of the two ceramic fragments.
[0047] The adhesive flows into the connection between the two ceramic fragments through the second connecting pipe 304 to fill the gap in the connection and complete the splicing and repair of the fragments. Through the precise delivery system, the adhesive can be evenly and accurately sprayed to the area to be repaired, avoiding too much or too little adhesive being applied to the ceramic fragments, thereby improving the repair effect and bonding strength.
[0048] A placing box 5 is installed on the outer side of the installation base plate 1, and the placing box 5 is used to place ceramic fragments. The outer side of the movable frame 804 is slidably connected to the inner wall of the limiting plate 802, and one end of the driving rod 803 is fixedly connected to the outer side of the movable column 406.
[0049] Working principle: When using the device, first, the electric turntable 601 is driven to rotate the first swing arm 602, and the output end of the second electric telescopic rod 606 is extended to drive the second swing arm 603 to swing up and down, and the output end of the first electric telescopic rod 605 is extended to drive the electric suction cup 604 to swing, and the electric suction cup 604 is moved to the inside of the placement box 5 to absorb the ceramic fragments inside the placement box 5. After the absorption is completed, the fragments are moved to the ceramic placed on the top of the placement plate 7 for splicing;
[0050] During the splicing process, the pump body 302 is started to introduce the adhesive inside the storage box 301 into the second connecting pipe 304 through the first connecting pipe 303, and then discharged into the connection between the two ceramic fragments through the second connecting pipe 304 for repairing;
[0051] After the splicing is completed, the output end at the bottom of the dual-axis motor 807 is started to drive the transmission rod 806 to rotate, and further drive the driving disk 801 to rotate coaxially, so that the fixed column 805 rotates eccentrically, and the fixed column 805 moves along the groove inside the movable frame 804. In this way, the movable frame 804 reciprocates along the inner wall of the limit plate 802 under the drive of the fixed column 805, thereby driving the movable column 406 to move synchronously. When the rubber piston 407 moves in a direction away from the movable column 406, the gas inside the fixed box 404 will be discharged into the heating device 401 through the second connecting pipe 403. The gas is heated by the electric heating wire inside the heating device 401 to form hot air, and finally discharged from the first connecting pipe 402. In this way, the connection between the two ceramic fragments can be quickly dried, which effectively shortens the time for splicing and repairing, and reduces the risk of secondary damage that may be caused by waiting for drying for a long time.
[0052] Finally, by starting the other output end of the dual-axis motor 807, the driving gear 9 is driven to rotate coaxially, which in turn drives the gear ring 10 to rotate, and further drives the placement plate 7 to rotate synchronously, making it convenient for the staff to repair the ceramics.
[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
