Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0026] Reference Figures 1 to 4 As shown, this utility model discloses an automatic polishing machine, which includes a processing base 10, a Y-axis module 20, a processing platform 30, a loading / unloading robot 40, and a lifting polishing module 50; wherein the processing base 10 is rectangular and has an opening at the top; the Y-axis module 20 is fixed to the base plate of the processing base 10, and a support frame 101 is also provided at the bottom of the processing base 10. In this embodiment, combined with Figure 4As shown, a total of four Y-axis modules 20 are included, each with a processing platform 30. Therefore, all four processing platforms 30 can be controlled independently, driving them to reciprocate on the Y-axis modules 20. Furthermore, the lifting and polishing module 50 is mounted above the processing platforms 30. In this embodiment, two lifting and polishing modules 50 are provided, each positioned above two processing platforms 30. The specific structure of the lifting and polishing module 50 will be further described below.

[0027] In this embodiment, combined with Figure 1 , Figure 4 As shown, the loading / unloading robot 40 is positioned between the parallel lifting and polishing modules 50, and is used to load and unload workpieces from the processing platform 30. Therefore, with this structure, the loading / unloading robot 40 can interface with the production line, transferring products to be processed from the production line to the processing platform 30. For example, in... Figure 4 In this process, the loading / unloading robot 40 first transfers the product to be processed onto the left processing platform 30. The left-side lifting and polishing module 50 then polishes the product on the left processing platform 30. Afterward, the loading / unloading robot 40 transfers the product to the right processing platform 30, where the right-side lifting and polishing module 50 polishes the product. Therefore, products can be polished sequentially on the same machine, improving polishing efficiency. After polishing is complete on the left processing platform 30, the loading / unloading robot 40 can unload the finished product. It should be noted that during loading and unloading, the Y-axis module 20 needs to move the processing platform 30 horizontally. For example, during loading, the Y-axis module 20 moves the processing platform 30 horizontally to below the loading / unloading robot 40; after loading, the Y-axis module 20 moves the processing platform 30 horizontally to below the lifting and polishing module 50.

[0028] Regarding the specific structure of the lifting and polishing module 50, this utility model provides a specific embodiment, combined with... Figure 2As shown, the lifting and polishing module 50 includes a gantry frame 501, a lifting drive mechanism 502, a lifting truss 503, a main polishing motor 504, a first transmission gear 505, a second transmission gear 506, and a polishing disc 507. Two sets of lifting drive mechanisms 502 are mounted opposite each other on the gantry frame 501. The two ends of the lifting truss 503 are respectively set on the two sets of lifting drive mechanisms 502, and the lifting truss 503 is lifted and lowered by the lifting drive mechanisms 502. The main polishing motor 504 is fixed on the lifting truss 503. The first transmission gear 505 is fixed on the motor shaft of the main polishing motor 504. Two sets of second transmission gears 506 are rotatably mounted opposite each other on the lifting truss 503, and both sets of second transmission gears 506 mesh with the first transmission gear 505. The polishing disc 507 and the second transmission gears 506 are fixed on the same rotating shaft. In this structure, the main polishing motor 504 drives the first transmission gear 505 to rotate, which in turn drives the second transmission gear 506 to rotate, thereby rotating the polishing disc 507 to achieve the polishing action on the product. This lifting polishing module 50 of the present invention uses a simple gear combination to drive the polishing disc 507 to rotate. Compared with polishing equipment with a complex structure, this structure has stronger stability and achieves the same polishing effect. The polishing disc 507 is directly driven to rotate by the first transmission gear 505 (or the second transmission gear 506), making power transmission more direct. Each lifting polishing module 50 includes two polishing discs 507. When polishing the product, the polishing discs directly cover the product, ensuring sufficient contact time between the polishing discs 507 and the product, thus improving polishing efficiency and yield. Therefore, the automatic polishing machine provided by this utility model can realize automatic feeding, automatic polishing and automatic unloading of products. Compared with manual feeding or manual polishing, it has higher feeding and polishing efficiency, more guaranteed polishing quality and better product consistency. In addition, due to the structural design of the lifting polishing module 50, the automatic polishing machine has better stability and lower equipment maintenance costs.

[0029] Regarding the aforementioned lifting drive mechanism 502, refer to Figure 2 , Figure 3As shown, this utility model provides a specific embodiment. The lifting drive mechanism 502 includes a fixed back plate 5021, a lifting motor 5022, a lifting slide rail 5023, a lifting slider 5024, and a lifting slide plate 5025. The fixed back plate 5021 is fixed on the gantry frame 501. The lifting motor 5022 and the lifting slide rail 5023 are both fixed on the fixed back plate 5021, and the lifting slide rail 5023 is vertically arranged. The lifting slider 5024 is slidably mounted on the lifting slide rail 5023. The lifting slide plate 5025 is fixedly connected to the lifting slider 5024. A lead screw (not shown in the figure) is connected to the motor shaft of the lifting motor 5022. A lead screw bearing (not shown in the figure) is installed on the back of the lifting slide plate 5025. The lead screw and the lead screw bearing are threadedly connected. The two ends of the lifting gantry 503 are fixedly connected to the lifting slider 5024 respectively. The use of a lifting drive mechanism 502 with a relative arrangement ensures the accuracy of the lifting gantry 503 during the lifting process. At the same time, since the polishing disc 507 will be subjected to a reverse force during the polishing process, the lifting drive mechanism 502 with this structure can ensure that the pressure applied to the lifting gantry 503 during the polishing process is constant, thereby making the pressure applied to the product by the polishing disc 507 constant, further improving the consistency of product polishing.

[0030] For the structure of the loading / unloading robot 40, refer to Figure 5 As shown, this utility model provides a specific embodiment where the loading / unloading robot 40 includes a moving module 401, a suction cup module 402, and multiple columns 403. The tops of the multiple columns 403 are provided with opposing horizontal rods 404. The moving module 401 is slidably mounted on the horizontal rods 404 and can reciprocate along the horizontal rods 404. In this embodiment, the direction of the horizontal rods 404 is defined as the Y-axis direction. The suction cup module 402 is located below the moving module 401 and is connected to the moving module 401 via a vertical connecting rod 405. Driven by the moving module 401, the suction cup module 402 can reciprocate along the vertical direction. In this embodiment, the vertical direction is the Z-axis direction; therefore, the suction cup module 402 can translate in both the X and Z axes. The multiple suction cups of the suction cup module 402 are connected to an external vacuum device, enabling the adsorption of products. It should be noted that the suction cup module 402 reciprocates in the Z-axis direction using a linear motor module. Since the structure of linear motor modules is common in existing technology, it will not be described in detail in this embodiment. Additionally, a gear is provided on the transverse rod 404, and the moving module 401 includes a gear driven by a motor. The meshing of the gear with a rack provides the power for the moving module 401 to reciprocate in the Y-axis direction.

[0031] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
