Multi-station jewelry rotary grinding integrated machine

Abstract

This invention discloses a multi-station jewelry polishing machine, relating to the field of jewelry processing technology. It includes a machine body, a cross-feed system mounted on the inner wall of the machine body, a servo robotic arm, a protective table, and a control system. It also includes two polishing components, both located inside the machine body, which are used for instantaneous soft contact between the jewelry and the polishing disc. In use, the jewelry gradually and softly cuts into the polishing disc from a flexible buffer pad. The elastic deformation of the pad absorbs the initial impact. As the jewelry exerts pressure on the polishing disc, the disc spring is compressed. The polishing disc, along with the buffer seat, slightly retracts along the axial direction of the limiting telescopic component, further absorbing the remaining impact and achieving a soft landing. The limiting telescopic component ensures that the floating mechanism is along the main shaft direction without radial sway, preventing scratches on the jewelry. These three components work together to form multiple layers of protection, transforming the original rigid contact into a flexible contact, preventing the jewelry from chipping or breaking.

Description

Technical Field

[0001] This invention relates to the field of jewelry processing technology, specifically to a multi-station integrated jewelry rotary polishing machine. Background Technology

[0002] Jewelry processing is the entire process of transforming raw materials such as jewels and precious metals into exquisite jewelry through a series of techniques including cutting, grinding, polishing, and setting. It combines artistry with technical precision. Jewelry grinding and finishing is a crucial step in jewelry processing, and multi-station rotary grinding machines, through continuous multi-station processing, replace manual frequent process changes, significantly improving the efficiency and consistency of jewelry grinding and finishing. It is one of the core equipment in intelligent jewelry manufacturing.

[0003] In existing technologies, the grinding disc in the jewelry polishing station is usually rigidly fixed to the motor spindle by bolts, making the motor, spindle and grinding disc form an integral structure. The drive system is a servo rigid feed, which causes a rigid impact to occur when the jewelry comes into contact with the grinding disc. Jewelry has high hardness but is also brittle. This rigid hard contact can easily cause instantaneous high-pressure scratches on the jewelry, which are difficult to completely eliminate in subsequent fine polishing, affecting the yield and luster. It can even cause the jewelry to chip or crack, and be scrapped.

[0004] Therefore, we propose a multi-station jewelry rotary polishing machine to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-station jewelry rotary polishing machine to solve the problem that when the multi-station jewelry rotary polishing machine mentioned in the background works, the contact between the jewelry and the polishing disc is a rigid hard contact at the moment. Under such circumstances, it is easy to cause instantaneous high-pressure scratches on the jewelry, which are difficult to completely eliminate in subsequent fine polishing, affecting the yield and luster, and may even cause the jewelry to chip or crack, and be scrapped directly.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-station jewelry polishing integrated machine, comprising a machine body, a cross feed system installed on the inner wall of the machine body, a servo robotic arm, a protective table and a control system, and further comprising polishing components, wherein two polishing components are provided, both located inside the machine body, and the polishing components are used for instantaneous soft contact between the jewelry and the polishing disc;

[0007] The locking assembly has two components, each sleeved on the outer surface of a polishing assembly. The locking assembly is used to lock the polishing assembly after the jewelry contact pressure has stabilized.

[0008] The unlocking component is provided in two parts, each located above a locking component, and is used to unlock the grinding component;

[0009] The driving component is used to drive the movement of the unlocking component;

[0010] Each of the aforementioned rotary grinding components includes a buffer seat, a flexible buffer pad, and a disc spring, wherein a limiting telescopic element is movably embedded inside the disc spring.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. When using this invention, the jewelry gradually and softly cuts into the polishing disc from the flexible buffer pad. The elastic deformation of the pad absorbs the initial impact. As the jewelry exerts pressure on the polishing disc, the disc spring is compressed. The polishing disc, along with the buffer seat, slightly retracts along the axial direction of the limiting telescopic component to further absorb the remaining impact and achieve a soft landing. The limiting telescopic component ensures that the floating is along the main axis without radial sway, avoiding scratches on the jewelry. The three work together to form multiple layers of protection, changing the original rigid hard contact into a flexible contact, preventing the jewelry from chipping or breaking.

[0013] 2. When using this invention, after the grinding pressure is stable, the locking buckle and the locking block snap together to lock the pressed disc spring, eliminating slight backlash during the processing, ensuring the dimensional accuracy and surface accuracy of the jewelry, and avoiding dimensional deviations caused by instability during the grinding process.

[0014] 3. In use, the drive assembly presses the unlocking ring downwards, forcing the locking block to slide out of the locking buckle and unlocking the disc spring. At this time, one grinding disc locks the disc spring during processing to ensure machining accuracy, while the other grinding disc unlocks the disc spring and automatically returns to its initial height under the spring's elasticity, preparing for the next workpiece contact. No manual adjustment is required, achieving continuous automated processing. The drive assembly can achieve synchronous locking and unlocking actions, ensuring seamless station switching, improving processing efficiency, and avoiding errors from manual operation.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-9 As shown, the present invention provides a technical solution: a multi-station jewelry polishing integrated machine, including a machine body 1, a cross feed system 2 installed on the inner wall of the machine body 1, a servo robotic arm 3, a protective table 4 and a control system 11, and also includes polishing components 5. There are two polishing components 5, both located inside the machine body 1. The polishing components 5 are used for instantaneous soft contact between the jewelry and the polishing disc to reduce the impact force caused by rigid hard contact.

[0028] Locking component 6, there are two locking components 6, which are respectively sleeved on the outer surface of the two grinding components 5. The locking component 6 is used to lock the grinding component 5 after the contact pressure of the jewelry is stable, so as to facilitate subsequent restoration of rigidity processing and ensure the accuracy of jewelry processing.

[0029] There are two unlocking components 7, located above the two locking components 6 respectively. The unlocking components 7 are used to unlock the grinding component 5, so that the grinding component 5 at this station can automatically reset to the initial height and prepare for the next workpiece contact.

[0030] The drive component 8 is used to drive the unlocking component 7 to move, thereby realizing the alternating unlocking of the rotary grinding components 5 on the two workstations;

[0031] Each rotary grinding assembly 5 includes a buffer seat 501, a flexible buffer pad 505, and a disc spring 506. The disc spring 506 has a movable limiting telescopic member 511. The buffer seat 501 is responsible for bearing the pressure of the jewelry contacting the grinding disc and transmitting it downwards. The flexible buffer pad 505 is used for the gradual soft cut between the jewelry and the grinding disc of the next station when the jewelry is switched from different stations. The disc spring 506 is used to absorb the impact. The limiting telescopic member 511 is used for the vertical axial floating of the grinding disc to avoid radial shaking and improve processing stability.

[0032] The top of the buffer seat 501 is movably fitted with an I-shaped mounting seat 502. The top of the I-shaped mounting seat 502 is provided with a grinding disc 504. A fixing ring 503 is bolted to the top of the outer surface of the I-shaped mounting seat 502. The bottom edge of the flexible buffer pad 505 is fixedly connected to the top of the fixing ring 503, and the bottom of the flexible buffer pad 505 is in contact with the top edge of the grinding disc 504.

[0033] In practical applications, two rotary grinding components 5 are provided, with both grinding discs 504 located inside the protective table 4, such as... Figure 1 As shown, after the adhesive rod clamp holds the jewelry, it is fixed by the pneumatic gripper on the servo robotic arm 3. The polishing angle between the adhesive rod clamp and the jewelry is adjusted by the servo robotic arm 3. The cross feed system 2 drives the servo robotic arm 3 to move onto the rotary polishing assembly 5 at the processing station. The flexible buffer pad 505 has an inclined structure, with the outer side higher than the inner side, as shown. Figure 5As shown, the bottom end contacts the top of the polishing disc 504. During the process of driving the jewelry from the edge onto the polishing disc 504, the jewelry first contacts the outer high side of the flexible buffer pad 505, then gradually slides along the inclined surface into the inner low side, and finally smoothly transitions onto the polishing disc 504. The flexible buffer pad 505 achieves a gradual soft cut into the jewelry, and the elastic deformation of the pad achieves flexible buffering. In addition, the wedge-shaped inclined structure allows the contact force between the jewelry and the polishing disc 504 to gradually increase from zero, rather than an instantaneous vertical impact, thus avoiding hard contact. While the jewelry exerts pressure on the grinding disc 504, the pressure is transmitted to the disc spring 506 through the I-shaped mounting base 502 and the buffer seat 501. The disc spring 506 and the limiting telescopic component 511 are compressed, causing the grinding disc 504 to move slightly downward along the axis of the limiting telescopic component 511, further absorbing the remaining impact and achieving a soft landing. Under the action of the rotary grinding assembly 5, the flexible buffer pad 505, the disc spring 506 and the limiting telescopic component 511 work together to form a micro-floating structure. A slight compression is generated at the moment of impact, which does not affect the rigidity of normal jewelry grinding. This achieves instantaneous soft contact between the jewelry and the grinding disc, avoiding instantaneous high-pressure scratches on the jewelry or causing the jewelry to chip. This solves the problem that when the jewelry and the grinding disc are in contact with a rigid hard contact at the moment of operation in a multi-station jewelry rotary grinding machine, instantaneous high-pressure scratches are easily caused on the jewelry. These scratches are difficult to completely eliminate in subsequent fine grinding, affecting the yield and luster, and may even cause the jewelry to chip or crack, resulting in direct scrapping.

[0034] It should also be noted that a bearing 508 is provided between the bottom outer surface of the I-shaped mounting base 502 and the top outer surface of the buffer base 501. A fixed base 507 is fixedly connected to the bottom of the disc spring 506. Several fixed rods 512 are fixedly installed at the bottom of the fixed base 507. An mounting plate 9 is fixedly installed inside the machine body 1. Two grinding motors 510 are fixedly connected to the bottom of the mounting plate 9. The bottom end of each fixed rod 512 is fixedly installed on the top of the mounting plate 9.

[0035] See Figures 3-5 As shown, a bearing 508 is installed between the I-shaped mounting base 502 and the buffer seat 501, facilitating better rotation of the I-shaped mounting base 502 on the outer surface of the buffer seat 501 without affecting the polishing effect of the polishing disc 504 on the jewelry. The fixing rod 512 cooperates with the fixing base 507 to support the disc spring 506 and the buffer seat 501. The polishing motor 510 provides stable cutting power for jewelry grinding. Starting the polishing motor 510 drives the limiting telescopic component 511 to rotate inside the disc spring 506, which in turn drives the polishing disc 504 to rotate and polish via the I-shaped mounting base 502.

[0036] It should also be noted that the limiting telescopic component 511 includes a first rotating shaft 5111, a second rotating shaft 5112 is movably sleeved on the outer surface of the first rotating shaft 5111, a plurality of locking blocks 5113 are fixedly installed on the outer surface of the bottom end of the first rotating shaft 5111, and a plurality of locking holes 5114 are opened on the outer surface of the top end of the second rotating shaft 5112, and the outer surface of each locking block 5113 is movably embedded in the inside of the locking hole 5114.

[0037] See Figure 5 As shown, the first locking hole 5114 and the first locking block 5113 cooperate to realize the movable limiting connection between the first rotating shaft 5111 and the second rotating shaft 5112, so that when the second rotating shaft 5112 rotates, it drives the first rotating shaft 5111 to rotate together, thereby driving the I-shaped mounting base 502 to rotate. At the same time, the first rotating shaft 511 can move axially inside the second rotating shaft 5112 to adapt to the slight axial movement of the grinding disc 504.

[0038] It should also be noted that the top end of the first rotating shaft 5111 extends through the buffer seat 501 to the interior of the I-shaped mounting seat 502, and the top end of the first rotating shaft 5111 is fixedly connected to the center of the top surface inside the I-shaped mounting seat 502. The bottom end of the second rotating shaft 5112 extends through to the bottom of the fixed seat 507, and the bottom end of the second rotating shaft 5112 is fixedly connected to the output end of the grinding motor 510.

[0039] See Figures 4-5 As shown, the first rotating shaft 5111 and the second rotating shaft 5112 cooperate to realize the connection between the grinding motor 510 and the I-shaped mounting base 502, so that the driving force of the grinding motor 510 is transmitted to the I-shaped mounting base 502 through the first rotating shaft 5111 and the second rotating shaft 5112.

[0040] It should also be noted that each locking assembly 6 includes a support plate 601, and several brackets 602 are equidistantly mounted on the top of the support plate 601. A locking block 603 is movably fitted on the outer surface of each bracket 602, and a strong spring 604 is fixedly connected to the bottom of one end of the locking block 603. Several locking buckles 509 are equidistantly mounted on the bottom of the outer surface of the buffer seat 501. The top of the other end of the locking block 603 contacts the bottom of the outer surface of the locking buckle 509. One end of the strong spring 604 is fixedly connected to the top of the support plate 601. The support plate 601 is fitted on the outer surface of the disc spring 506, and the outer surface of the support plate 601 is fixedly installed on the inner wall of the body 1.

[0041] See Figures 4-6 and Figures 8-9As shown, when the I-shaped mounting base 502 moves downward under force, it pushes the buffer base 501 to move downward together, which in turn drives multiple locking buckles 509 to move downward together. The bottom of the locking buckle 509 and the contact surface with the locking block 603 are arc-shaped. When the locking buckle 509 moves downward, it generates a thrust on the arc-shaped end of the locking block 603, causing it to rotate around the central axis of the bracket 602. At the same time, it pulls the strong spring 604 to unfold. When the arc-shaped end of the locking block 603 is inside the locking buckle 509, the strong spring 604 pulls the locking block 603 to rotate in the opposite direction, so that its arc-shaped end is locked in the locking buckle 509, thereby locking the compressed disc spring 506 and maintaining a slight pressure state, so that the polishing disc 504 and the jewelry maintain a rigid processing state, improving the processing effect.

[0042] It should also be noted that each unlocking component 7 includes an unlocking ring 701. Several spring telescopic rods 702 are fixedly connected to the bottom of the unlocking ring 701. Several push pins 703 are equidistantly installed at the bottom of the unlocking ring 701, and the push pins 703 are located at the top of one end of the locking block 603. The unlocking ring 701 is movably sleeved on the outer surface of the disc spring 506 and located at the top of the support plate 601. The bottom end of each spring telescopic rod 702 is fixedly installed on the top of the support plate 601.

[0043] See Figure 6 and Figures 8-9 As shown, under the drive of the drive assembly 8, the unlocking ring 701 is subjected to a downward pushing force, which squeezes the spring telescopic rod 702, causing it to retract. At the same time, the push column 703 moves downward and contacts the spring end of the locking block 603, generating a downward pushing force on the spring end of the locking block 603. This causes the arc-shaped end of the locking block 603 to rotate out of the locking buckle 509. At this time, the locking buckle 509 loses its limit, and the disc spring 506 loses its lock. Under the elastic force of the disc spring 506, the I-shaped mounting base 502 and the polishing disc 504 are pushed axially upward to reset, without affecting the instantaneous flexible contact between the next jewelry workpiece and the polishing disc 504.

[0044] It should also be noted that the drive assembly 8 includes a connecting plate 801. A forward and reverse motor 802 is mounted on the front surface of the top of the connecting plate 801 via an auxiliary frame. A rotating rod 803 is fixedly mounted on the output end of the forward and reverse motor 802. A rotating block 804 is fixedly mounted on the outer surface of the rotating rod 803. Two pushers 806 are fixedly mounted on the outer surface of the rotating block 804. Two push rods 807 are fixedly mounted on the bottom of the two pushers 806. The pushers 806 are located on the top of the unlocking ring 701. A support block 805 is fixedly mounted on the rear surface of the top of the connecting plate 801. One end of the rotating rod 803 is movably embedded inside the support block 805. The connecting plate 801 and the support plate 601 are fixedly connected.

[0045] See Figures 6-7As shown, when the jewelry moves from one processing station to another (e.g., from left to right), the forward and reverse motors 802 drive the rotating rod 803 and the rotating block 804 to rotate, which in turn drives the two pushers 806 to rotate together. This causes the left pusher 806 to rotate upward and the right pusher 806 to rotate downward. At the same time, the two push rods 807 move downward and contact the unlocking assembly 7. As the push rods 807 continue to push, the unlocking assembly 7 is forced to move downward, thereby unlocking the grinding assembly 5.

[0046] By rotating the forward and reverse motors 802, the two pusher frames 806 are driven to rotate back and forth, realizing the alternating unlocking operation of the two rotary grinding components 5. This ensures that the processing and reset of the two workstations are synchronized, eliminating the need for manual adjustment, achieving continuous automated processing, and improving efficiency.

[0047] It should also be noted that the protective platform 4 is bolted to the front surface of the top of the machine body 1, the servo robotic arm 3 is mounted on the front surface of the cross feed system 2, the protective platform 4 has two movable holes 10 inside, the center of the outer surface of the two I-shaped mounting bases 502 are respectively movably embedded in the two movable holes 10, and the waste liquid pipe 12 is fixedly connected to the rear surface of the bottom of the protective platform 4.

[0048] See Figures 1-3 As shown, the cross feed system 2 drives the servo robotic arm 3 to move left and right and up and down. The servo robotic arm 3 drives the jewelry to rotate, performing polishing at different angles. The movable hole 10 facilitates the rotation of the I-shaped mounting base 502, and the protective table 4 is used for jewelry polishing protection to prevent debris from flying.

[0049] Please see Figures 1-9As shown, the overall effect and working principle of the mechanism are as follows: The servo robotic arm 3 adjusts the polishing angle of the sticky rod clamp and the jewelry. The cross feed system 2 drives the servo robotic arm 3 and the jewelry to move to the rotary polishing assembly 5 at the workstation. During the movement, the jewelry first contacts the outer high side of the flexible buffer pad 505, then gradually slides along the inclined surface into the inner low side, and finally smoothly transitions to the polishing disc 504. While the jewelry exerts pressure on the polishing disc 504, the pressure is transmitted to the disc spring 506 through the I-shaped mounting base 502 and the buffer seat 501. The disc spring 506 and the limiting telescopic member 511 are compressed, causing the polishing disc 504 to move slightly downward along the axial direction of the limiting telescopic member 511, achieving a soft landing. When the buffer seat 501 moves downward, it drives multiple locking buckles 509 to move downward together. The arc-shaped end of the locking block 603 is first subjected to force and rotates downward, then springs back and locks into the locking buckle 509, locking the compressed disc spring 506. The forward and reverse motors 802 drive the rotating rod 803 and the rotating block 804 to rotate, which in turn drives the two pusher frames 806 to rotate together. The pusher rod 807 presses down on the unlocking ring 701 and squeezes the spring telescopic rod 702 to retract it. At the same time, the pusher column 703 generates a downward push force on the spring end of the locking block 603, causing the arc-shaped end of the locking block 603 to rotate out of the locking buckle 509. The disc spring 506 loses its lock. Under the elastic force of the disc spring 506, the I-shaped mounting base 502 and the grinding disc 504 are pushed to move upward axially to reset. Through the forward and reverse rotation of the forward and reverse motors 802, the alternating unlocking operation of the two rotary grinding components 5 is realized.

[0050] Among them, the cross feed system 2, servo robotic arm 3, forward and reverse motor 802, grinding motor 510 and control system 11 are all existing technologies, and their components and operating principles are all publicly available technologies, so they will not be explained in detail here.

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
