Detailed Implementation

[0026] Example 1, please refer to Figures 1 to 5 This is a schematic diagram of an automated polishing mechanism provided by this utility model. The automated polishing mechanism includes: a frame 10, a material tray 20, a workpiece positioning platform 30, a cover plate positioning platform 40, a workpiece positioning assembly 50, and a material transfer and polishing assembly 60, all mounted on the frame 10. It is conceivable that this automated polishing mechanism also includes other functional components and specific structures, such as electrical connection components, control components, and installation structures, all of which are well-known to those skilled in the art and will not be described in detail here.

[0027] The frame 10 serves as the mounting carrier, with a flat platform at the top to facilitate the assembly and installation of various components.

[0028] like Figure 5 As shown, the tray 20 is used to hold workpieces, including workpieces to be processed and processed workpieces. Multiple trays 20 can also be provided, each storing workpieces to be processed and processed workpieces respectively. A lifting seat 21 is provided at the bottom of the tray 20 on the frame 10, forming a clamping gap 22 between the bottom of the tray 20 and the lifting seat 21. The tray 20 also has through-holes to prevent negative pressure adhesion of the workpiece on the tray 20, facilitating workpiece transfer. The clamping gap 22 also facilitates lateral clamping of the tray 20 as a whole. Ideally, a positioning post 23 is provided on the upper circumferential edge of the lifting seat 21, and a sleeve 24 is provided at the bottom of the tray 20 for the positioning post 23 to be inserted. The sleeve 24 elastically fits onto the positioning post 23, achieving the positioning and installation of the tray 20.

[0029] like Figures 1 to 3As shown, in this embodiment, the workpiece positioning platform 30 is used for secondary positioning of the workpiece before polishing. Specifically, the workpiece on the tray 20 is first transferred to the workpiece positioning platform 30 for precise positioning, and then accurately transferred to the workpiece positioning assembly 50. Specifically, the workpiece positioning platform 30 is provided with an inclined slope 31, and a reference stop 32 is provided on the inclined slope 31. The workpiece is positioned by freely sliding down the inclined slope 31 and by the reference stop 32, which typically abuts against both sides of the workpiece. Alternatively, the workpiece's own structure can be utilized; for example, the workpiece may have a rectangular groove. The reference stop 32 is placed on the inclined slope 31 and embedded in the rectangular groove. The relative displacement between the rectangular groove and the reference stop 32 completes the positioning.

[0030] In this embodiment, the workpiece positioning assembly 50 includes a polishing positioning platform 51 mounted on the frame 10. The polishing positioning platform 51 and the workpiece are positioned by a positioning pin insertion method. The circumferential edge of the workpiece protrudes from the polishing positioning platform 51, facilitating the contact of the material transfer polishing assembly 60 with the circumferential edge of the workpiece. A support column 54 higher than the frame 10 is provided at the bottom of the polishing positioning platform 51 to raise the workpiece polishing position, providing sufficient space for displacement and polishing operations. The polishing positioning platform 51 is provided with a cover plate 52 covering the upper end of the workpiece, and a fixing structure 53 passing through the polishing positioning platform 51 and capable of pressing down on the cover plate 52 in the opposite direction. The fixing structure 53 is used to fix the cover plate 52 to restrict the upper end of the workpiece. Specifically, the fixing structure 53 includes a positioning driver 531 mounted on the polishing positioning platform 51. The positioning driver 531 is a cylinder, rotatably connected to the output end of the positioning driver 531 and capable of passing through the cover. The rotatable connection is achieved by defining the spiral guide channel of the positioning block 532, allowing the positioning block 532 to rotate during its ascent or descent, and simultaneously move aside when the cover 52 is tightened or loosened. This method is existing technology and will not be described in detail here. More simply, when the thickness of the workpiece is determined, the positioning driver 531 can be a rotary motor, directly driving the positioning block 532 to rotate and press against the upper end of the cover.

[0031] The cover plate positioning platform 40 is used as the storage position for the cover plate 52 when picking up and putting down workpieces.

[0032] like Figure 4 As shown, in this embodiment, the material transfer and polishing assembly 60 includes a robotic arm 61 mounted on the frame 10. The robotic arm 61 is a conventional multi-axis robotic arm, which enables 3-axis coordinate movement of the output end. A mounting frame 62 is provided at the output end of the robotic arm 61. The mounting frame 62 is a frame structure that serves as a mounting carrier, facilitating the assembly of various components and allowing for a layered installation method that prevents interference between components.

[0033] An adsorption structure 63 is installed on the mounting frame 62. The adsorption structure 63 includes strip-shaped mounting holes 631 spaced apart on the mounting frame 62. Suction cups 632 that can pass through the ends of the mounting frame 62 are spaced apart in the strip-shaped mounting holes 631. The strip-shaped mounting holes 631 facilitate the adjustment of the installation spacing of the suction cups 632. Multiple suction cups 632 are connected to an external air pump for holding the workpiece and the cover plate 52. The suction cups 632 first hold the workpiece, and the robot arm 61 transfers it from the material tray 20 to the workpiece positioning platform 30 for preliminary positioning. Then it is transferred to the polishing positioning platform 51 for precise positioning. Finally, the cover plate 52 is held from the cover plate positioning platform 40 to the polishing positioning platform 51. It can be imagined that the height of the cover plate positioning platform 40 is similar to the height of the polishing positioning platform 51, which reduces the moving distance of the robot arm 61 and increases the accuracy of the transfer.

[0034] The mounting frame 62 is provided with clamping structures 64 located on both sides of the suction structure 63. The clamping structures 64 are used to transfer the material tray 20. Specifically, the clamping structure 64 includes a clamping driver 641 mounted on the mounting frame 62. The clamping driver 641 is a cylinder. At the output end of the clamping driver 641, there are clamping side plates 642 located on both sides of the suction cup 632, and clamping fingers 643 located at the end of the clamping side plates 642 away from the mounting frame 62. The clamping fingers 643 correspond to the thickness of the material tray 20. The clamping driver 641 drives the clamping side plates 642 to open or close the clamping fingers 643. The fingers clamp and abut against the outer side wall of the material tray 20, and then the displacement is achieved by the robot arm 61.

[0035] A polishing structure 65 is provided on the mounting bracket 62, away from the adsorption structure 63 and the clamping structure 64. The polishing structure 65 can be any of a polishing machine or sandpaper, and the polishing structure 65 does not interfere with the adsorption structure 63 and the clamping structure 64. The output end of the polishing structure 65 protrudes from the mounting bracket 62 to avoid interference between the mounting bracket 62 and the polishing positioning platform 51.

[0036] The material transfer and polishing assembly 60 integrates the adsorption structure 63, clamping structure 64, and polishing structure 65 into a single robotic arm 61 at the output end, occupying little space. During operation, the components do not interfere with each other, and the automated operation provides precise positioning and convenient transfer, thus improving overall work efficiency.

[0037] Example 2: This utility model also provides a fully automated production line with the automated polishing mechanism as described above. Except for the automated polishing mechanism, all other components are existing technology or commercially available parts.

[0038] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
