Description

Technical Field

[0001] This utility model belongs to the field of polishing equipment, specifically relating to a polishing support component, a polishing support device, and a polishing system. Background Technology

[0002] In the field of precision manufacturing, the ability to stably fix and adjust workpieces at multiple angles during polishing is crucial for improving processing quality. Traditional polishing equipment typically uses mechanical clamping or vacuum adsorption to fix workpieces, but these methods have significant limitations. For example, mechanical clamping devices are prone to deformation or damage when clamping complex curved surfaces or thin-walled workpieces, and rapid assembly and disassembly are difficult. While existing vacuum adsorption devices can reduce contact damage, their piping layout is mostly located outside the equipment, making them susceptible to vibration and debris interference in the polishing area, resulting in insufficient adsorption stability. Furthermore, angle adjustment mechanisms often employ multi-axis linkage or manual adjustment, which are complex in structure and have limited precision, making it difficult to meet the requirements of high-precision polishing for continuous multi-angle adjustment. Especially for irregularly shaped workpieces, traditional equipment suffers from poor coordination between angle adjustment and fixation, easily leading to uneven polishing or workpiece displacement, severely impacting processing efficiency and finished product consistency.

[0036] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0037] As attached Figure 1 - Appendix Figure 4As shown, this utility model provides a polishing support assembly 1, including a support platform 11, a rotation drive mechanism I 12, a negative pressure suction mechanism 13, and a bracket 14. The support platform 11 is used to support the workpiece 4 to be polished. The rotation drive mechanism I 12 is used to adjust the angle of the support platform 11, thereby allowing the polishing mechanism 2 to polish different positions of the workpiece 4. The negative pressure suction mechanism 13 is used to firmly fix the workpiece 4 to be polished on the support platform 11 to ensure the stability of the workpiece during the polishing process. The bracket 14 is used to fix the support platform 11, the rotation drive mechanism I 12, and the negative pressure suction mechanism 13, making them form a whole and improving the structural compactness.

[0038] The rotation drive mechanism I12 can be a motor, a rotary cylinder, or a rotary hydraulic cylinder. Preferably, the rotation drive mechanism I12 is a motor, which facilitates precise control. The main body 121 of the rotation drive mechanism I12 is mounted on the bracket 14, and the end of the rotation shaft 122 of the rotation drive mechanism I12 is fixed to the support platform 11; that is, the rotation of the rotation shaft 122 of the rotation drive mechanism I12 can drive the support platform 11 to rotate.

[0039] The rotating shaft 122 is hollow inside. The negative pressure suction mechanism 13 includes a negative pressure suction chamber I 131 disposed on the bearing surface of the bearing platform 11 and a negative pressure pipe 132 passing through the hollow rotating shaft 122. One end of the negative pressure pipe 132 is connected to the negative pressure suction chamber I 131, and the other end extends out of the rotating shaft 122 for connecting to a negative pressure generating device. The negative pressure suction chamber I 131 is used to adsorb the workpiece 4 to be polished onto the bearing surface of the bearing platform 11. The negative pressure pipe 132 is used to connect the negative pressure suction chamber I 131 and the negative pressure generating device.

[0040] The polishing support assembly 1 provided by this utility model, through the arrangement of the rotation drive mechanism I12 and the negative pressure suction mechanism 13, enables the support platform 11 to rotate and the workpiece 4 to be polished to be suctioned under negative pressure, and allows for angle adjustment and stable fixation of the workpiece 4 to be polished. By setting the rotation shaft 122 as a hollow structure and utilizing the hollowness of the rotation shaft 122 to arrange the negative pressure pipe 132, it is easy to connect the negative pressure suction cavity I131 on the support platform 11 located in the polishing area to the negative pressure generating device, so that the negative pressure generating device and the negative pressure pipe 132 can be far away from the polishing area, simplifying the connection difficulty and improving the connection stability.

[0041] In one embodiment, the negative pressure suction chamber I 131 includes a strip-shaped groove disposed on the plane of the support platform 11 and a negative pressure hole communicating with the strip-shaped groove. Multiple strip-shaped grooves are provided and interconnected, and the negative pressure hole is connected to the negative pressure pipe 132. The strip-shaped grooves allow for negative pressure suction over a large area of ​​the support platform 11, thereby improving the stability of the workpiece 4 to be polished and reducing the possibility of edge warping of the workpiece 4. The negative pressure hole connects the strip-shaped groove and the negative pressure pipe 132, simplifying the connection between the strip-shaped groove and the negative pressure pipe 132.

[0042] In one embodiment, the negative pressure pipe 132 includes a vertical portion 1321 and a horizontal portion 1322 connected in sequence. The vertical portion 1321 passes through the hollow of the rotating shaft 122, and the horizontal portion 1322 is located outside the rotating shaft 122 for connecting to the negative pressure generating device. That is, the negative pressure pipe 132 has an L-shaped structure. This arrangement allows the negative pressure pipe 132 to pass through the side of the rotating drive mechanism I12 and connect to the negative pressure generating device, thereby ensuring the compactness of the polishing support assembly 1.

[0043] In one embodiment, the vertical part 1321 is rotatably sealed to the horizontal part 1322, and the rotation axis of the rotatably sealed connection is coaxial with the rotation axis of the rotation shaft 122.

[0044] Alternatively, the vertical portion 1321 is rotatably and sealingly connected to the supporting platform 11. In this case, the negative pressure suction mechanism 13 includes a negative pressure interface 133 connected to a negative pressure hole on the supporting platform 11. The negative pressure interface 133 is rotatably and sealingly connected to the vertical portion 1321.

[0045] In this embodiment, when the bearing platform 11 rotates, the connection between the negative pressure pipe 132 and the negative pressure generating device does not rotate with it, thereby simplifying the connection between the negative pressure pipe 132 and the negative pressure generating device and improving its connection stability.

[0046] In one embodiment, the polishing support assembly 1 further includes a moving mechanism disposed between the rotation drive mechanism I 12 and the support 14. In this case, the rotation drive mechanism I 12 is indirectly mounted on the support 14 via the moving mechanism, which drives the rotation drive mechanism I 12 and the support platform 11 to adjust their positions, thereby enabling fine-tuning of the position of the workpiece 4 to be polished, fixed on the support platform 11, to achieve precise polishing. Furthermore, during the polishing process of the polishing mechanism 2 on the workpiece 4, if excessive pressure occurs, the moving mechanism can also cooperate with a pressure sensing device to drive the support platform 11 and the workpiece 4 to move, thereby reducing the polishing pressure and achieving polishing buffering.

[0047] In one embodiment, the moving mechanism is a lifting drive mechanism 18 and / or a horizontal linear drive mechanism 19. Preferably, the moving mechanism is a lifting drive mechanism 18 and a horizontal linear drive mechanism 19. In this case, the body of the horizontal linear drive mechanism 19 is fixedly mounted on the bracket 14, the body of the lifting drive mechanism 18 is fixedly mounted on the output end of the horizontal linear drive mechanism 19, and the body 121 of the rotation drive mechanism I12 is fixedly mounted on the output end of the lifting drive mechanism 18.

[0048] By equipping the lifting drive mechanism 18, the position adjustment and buffering of the bearing platform 11 and the workpiece 4 to be polished in the Z direction can be realized. By equipping the horizontal linear drive mechanism 19, combined with the rotation drive mechanism I 12, the position adjustment and buffering of the bearing platform 11 and the workpiece 4 to be polished in the X and Y directions can be realized.

[0049] In one embodiment, a two-dimensional force sensor 110 is provided between the moving mechanism and the rotation drive mechanism I12. Preferably, the two-dimensional force sensor 110 is located on the output end of the lifting drive mechanism 18, while the rotation drive mechanism I12 is fixed to the two-dimensional force sensor 110. The two-dimensional force sensor 110 can be used to monitor the pressure in the Y-axis and X-axis (or Y-axis) directions, thereby obtaining the polishing pressure of the bearing platform 11 and the workpiece 4 to be polished. The moving mechanism can act as a buffer device. When the two-dimensional force sensor 110 detects that the polishing pressure in the Y-axis and X-axis (or Y-axis) directions on the workpiece 4 to be polished is too high, the moving mechanism can be controlled to move the bearing platform 11 in the Y-axis and X-axis (or Y-axis) directions to reduce its polishing pressure. In addition, when multiple sets of polishing bearing components 1 are arranged, multiple two-dimensional force sensors 110 can also be used to control the polishing pressure of multiple sets of workpieces 4 to be polished to always be balanced, ensuring the polishing uniformity of multiple products.

[0050] In one embodiment, a connecting seat 15 is further provided between the rotating shaft 122 and the bearing platform 11, the connecting seat 15 being used to connect the rotating shaft 122 and the bearing platform 11;

[0051] The connecting seat 15 extends outwardly and is provided with a protective cover 16 that covers the rotary drive mechanism I 12. This arrangement provides physical protection for the rotary drive mechanism I 12, preventing the polishing mechanism 2 or polishing debris from affecting it, thus improving the service life and operational stability of the rotary drive mechanism I 12. Additionally, in embodiments equipped with a two-dimensional force sensor 110 and a moving mechanism, the protective cover 16 can also provide physical protection for both.

[0052] Reference Appendix Figure 4The present invention also provides a polishing support device, including an outer cover 17 and a plurality of polishing support components 1 arranged at equal intervals on the outer cover 17;

[0053] The bracket 14 and the moving mechanism are housed within the outer cover 17. The outer cover 17 provides physical protection for the bracket 14, the lifting drive mechanism 18, and / or the horizontal linear drive mechanism 19, preventing polishing debris from interfering with their use. The bearing platform 11, the rotation drive mechanism I 12, and the protective cover 16 are also housed within the outer cover 17. In this case, the protective cover 16 provides physical protection for the portion exposed outside the outer cover 17. The cooperation between the protective cover 16 and the outer cover 17 provides physical protection for the electrical components of the polishing bearing assembly 1.

[0054] Reference Appendix Figure 6 The present invention also provides a polishing system, including a polishing mechanism 2 and the aforementioned polishing support device;

[0055] Reference Appendix Figure 5 The polishing mechanism 2 includes a support frame 21, a rotating mechanism 22, and a polishing head 23;

[0056] The cross-sectional shape of the support frame 21 is a regular polygon. Each side of the support frame 21 is provided with a set of multiple polishing heads 23 arranged at equal intervals along the length direction. The multiple sets of polishing heads 23 can have different polishing precision, thereby realizing different precision processing of the workpiece 4 to be polished, or realizing sequential processing of the workpiece 4 to be polished from rough processing to fine processing.

[0057] The rotating mechanism 22 is used to drive any one set of polishing heads 23 to align with the plurality of bearing platforms 11.

[0058] Preferably, the rotating mechanism 22 includes two sets of symmetrically arranged L-shaped supports 221, with the two ends of the support frame 21 rotatably mounted on the two L-shaped supports 221 respectively. The rotating mechanism 22 also includes a rotating drive mechanism II 222 mounted on the L-shaped supports 221, which is used to drive the support frame 21 to rotate.

[0059] Reference Appendix Figure 7 - Appendix Figure 8This utility model also provides a polishing loading assembly 3, used to load the workpiece 4 to be polished onto the polishing support assembly 1 for polishing by the polishing mechanism 2. The polishing loading assembly 3 includes a material box 31, a transfer platform 32, a transfer platform loading mechanism 33, and a polishing loading mechanism 34; wherein the material box 31 is used to store the workpiece 4 to be polished. The transfer platform 32 is used to transfer the workpiece 4 to be polished and adjust its position. The transfer platform loading mechanism 33 is used to transfer the workpiece 4 to be polished from the material box 31 onto the transfer platform 32. The polishing loading mechanism 34 is used to transfer the workpiece 4 to be polished from the transfer platform 32 onto the polishing support assembly 1.

[0060] The transfer platform 32 is equipped with a positioning fixture 321, and the transfer platform loading mechanism 33 is used to transfer the workpiece 4 to be polished in the raw material box 31 to the positioning fixture 321 for positioning.

[0061] The polishing loading mechanism 34 is used to grab the positioned workpiece 4 to be polished and place it onto the polishing support assembly 1 for polishing.

[0062] The polishing feeding component 3 provided by this utility model allows the polishing feeding mechanism 34 to accurately position and grasp the workpiece 4 to be polished after it is positioned by the positioning fixture 321. This ensures that the polishing feeding mechanism 34 accurately transfers the workpiece 4 to be polished onto the polishing bearing component 1, ultimately achieving precise polishing of the workpiece 4 by the polishing mechanism 2 without the need for a position sensing system.

[0063] In one embodiment, the positioning fixture 321 includes a support platform 3211 and two sets of positioning column mechanisms 3212 respectively disposed on one side of the support platform 3211 in the X direction and one side in the Y direction.

[0064] The support platform 3211 is used to receive the workpiece 4 to be polished, and two sets of positioning column mechanisms 3212 are used to position one side of the workpiece 4 in the X direction and one side in the Y direction, respectively. The size of the support platform 3211 is smaller than the size of the workpiece 4 to be polished. After the workpiece 4 is placed on the support platform 3211, its side will protrude beyond the side of the support platform 3211. At this time, the position of the workpiece 4 to be polished only needs to be further adjusted by the transfer platform loading mechanism 33 so that both sides of the workpiece 4 simultaneously abut against the two sets of positioning column mechanisms 3212, thus completing the positioning of the workpiece 4. The entire positioning process is convenient, quick, and has high positioning accuracy.

[0065] In one embodiment, at least one set of the positioning post mechanisms 3212 includes a sliding drive mechanism 32121 and a post 32122 disposed on the output slider of the sliding drive mechanism 32121. That is, the post 32122 of at least one set of positioning post mechanisms 3212 can be moved and adjusted in position, thereby adapting to the positioning of workpieces 4 to be polished of different sizes.

[0066] In one embodiment, the surface of the support platform 3211 is provided with a negative pressure suction chamber II 32111, which is connected to a negative pressure generating device. The negative pressure suction chamber II 32111 can adsorb the workpiece 4 to be polished onto the support platform 3211 during and after the position adjustment process, thus preventing displacement of the workpiece 4 and avoiding a decrease in positioning accuracy.

[0067] In one embodiment, the negative pressure suction chamber II 32111 is an interconnected strip groove arranged on the bearing plane of the bearing platform 3211. The strip groove can increase the negative pressure suction area on the bearing platform 3211, thereby improving the stability of negative pressure suction.

[0068] In one embodiment, the transfer platform loading mechanism 33 includes an XYZ three-axis moving platform 331 and a negative pressure gripping robot 332 mounted on the XYZ three-axis moving platform 331. The XYZ three-axis moving platform 331 includes an X-axis moving mechanism I 3311, a Y-axis moving mechanism 3312, and a Z-axis moving mechanism 3313. Preferably, the Y-axis moving mechanism 3312 is fixed to the output end of the X-axis moving mechanism I 3311, the Z-axis moving mechanism 3313 is fixed to the output end of the Y-axis moving mechanism 3312, and the negative pressure gripping robot 332 is fixed to the output end of the Z-axis moving mechanism 3313. This allows the negative pressure gripping robot 332 to move in the XYZ three-axis direction, thereby moving the workpiece 4 to be polished in the material box 31 to the transfer platform 32.

[0069] In one embodiment, the positioning fixture 321 is arranged in several groups at equal intervals along the X direction of the transfer platform 32;

[0070] The polishing loading mechanism 34 includes a gripping mechanism mounted on the Y-axis moving mechanism 3312 of the XYZ three-axis moving platform 331. At this time, the transfer platform loading mechanism 33 can sequentially load multiple sets of workpieces 4 to be polished from the positioning fixtures 321. After multiple workpieces 4 to be polished are loaded and positioned, the polishing loading mechanism 34 simultaneously grips multiple workpieces 4 to be polished and transfers them to the polishing support assembly 1. This greatly improves polishing efficiency. Furthermore, since the polishing loading mechanism 34 is mounted on the Y-axis moving mechanism 3312 of the XYZ three-axis moving platform 331, it can directly utilize the X-axis moving mechanism Ⅰ 3311 of the XYZ three-axis moving platform 331 for X-direction displacement, enabling the polishing loading mechanism 34 to rotate from above the positioning fixtures 321 along the X-direction to above the polishing support assembly, thus saving one moving mechanism.

[0071] In one embodiment, the gripping mechanism includes a Z-axis lifting mechanism 341 and a plurality of negative pressure suction heads 342 equidistantly arranged along the X-direction on the output end of the Z-axis lifting mechanism 341. By setting the Z-axis lifting mechanism 341, the workpiece 4 to be polished, sucked by the negative pressure suction heads 342, can be lowered onto the polishing support device. At this time, the Z-axis lifting of the negative pressure suction heads 342 and the Z-axis of the negative pressure gripping robot 332 are independent of each other, so that the loading of the workpiece 4 to be polished onto the transfer platform 32 and the loading of the workpiece 4 to be polished on the transfer platform 32 onto the polishing support device can be carried out independently, making reasonable use of time.

[0072] In one embodiment, the transfer platform 32 is also provided with a finished product station.

[0073] It also includes a finished product box 35, with the raw material box 31 and the finished product box 35 correspondingly arranged on both sides of the transfer platform 32. The finished product station is used to hold the polished finished workpiece 5. At this time, after the polishing mechanism 2 finishes polishing the workpiece 4 to be polished on the polishing support device, the polishing loading mechanism 34 can unload the finished workpiece 5 to the finished product station in a reverse action. Finally, the finished workpiece 5 located at the finished product station is transferred to the finished product box 35 by the transfer platform loading mechanism 33. This realizes the loading and unloading of the polishing support device, greatly improving the practicality of the device.

[0074] In one embodiment, the transfer platform 32 can be mounted on the X-axis moving mechanism II 36, and thus can move in the X-axis direction, which facilitates the switching of the transfer platform loading mechanism 33 between the transfer platform 32 and the finished product station, reducing the stroke load of the X-axis moving mechanism I 3311.

[0075] This utility model also provides a polishing system, including the above-mentioned polishing feeding component 3.

[0076] The above description is merely an embodiment and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations, modifications, or alterations to the technical solution of this utility model without departing from its scope. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model, without departing from its scope, should fall within the protection scope of this utility model.
