[0002] Touchscreen displays are now widely used in mobile phones, smart phones, and even automotive instrument panels and center consoles. These displays require a glass cover to protect them and provide a surface for touch sensing. During the cover production process, polishing is necessary. Polishing is a process that uses mechanical, chemical, or electrochemical processes to reduce the surface roughness of a workpiece to achieve a bright, smooth surface. Polishing is a finishing process that uses polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece.

[0003] Conventional polishing equipment is typically equipped with a loading and unloading mechanism to automate the loading, unloading, and polishing of workpieces. However, due to structural limitations, the polishing equipment must be stopped during the loading or unloading process, and polishing can only resume after loading or unloading is complete.

[0045] The concept, specific structure and technical effects of the present invention will be clearly and completely described below in combination with the embodiments and drawings, so as to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present invention can be combined with each other without conflict.

[0046] Refer to Figures 1 to 3As shown, the present invention discloses an efficient polishing machine, which includes a workbench 10, a first polishing mechanism 50, a second polishing mechanism 40, a loading and unloading manipulator 20, and a plurality of polishing jigs 30; in combination with Figure 1 , the workbench 10 is arranged above the base 104, and a protective cover 101 is arranged on the workbench 10. One side of the protective cover 101 has an electric control cabinet 102, and a control panel 108 is arranged on the electric control cabinet 102. An exhaust hole 103 is reserved at the top of the protective cover 101. The first polishing mechanism 50, the second polishing mechanism 40, and the plurality of polishing jigs 30 are all located inside the protective cover 101.

[0047] Continue to refer to Figure 2 、 Figure 3 As shown, the first polishing mechanism 50 and the second polishing mechanism 40 are arranged side by side on the workbench 10. The loading and unloading manipulator 20 is located between the first polishing mechanism 50 and the second polishing mechanism 40. The structures of the first polishing mechanism 50 and the second polishing mechanism 40 are exactly the same. For the convenience of understanding, only the specific structure of the first polishing mechanism 50 will be described in detail in the following text.

[0048] Refer to Figure 3 As shown, the plurality of polishing jigs 30 are all arranged on the workbench 10 and are located below the first polishing mechanism 50, the second polishing mechanism 40, and the loading and unloading manipulator 20. In this embodiment, a total of four polishing jigs 30 are provided, and every two polishing jigs 30 are arranged side by side below the first polishing mechanism 50 and the second polishing mechanism 40. Further, a loading transition tray 105 and an unloading transition tray 106 are respectively arranged on both sides of the workbench 10. The loading and unloading manipulator 20 transfers the workpiece in the loading transition tray 105 into the polishing jig 30, and the first polishing mechanism 50 and the second polishing mechanism 40 process the workpiece in the polishing jig 30. The loading and unloading manipulator 20 is also used to transfer the processed workpiece from the polishing jig 30 into the unloading transition tray 106.

[0049] In addition, in the above embodiment, a Y-axis motion module 107 is further arranged on the workbench 10. The polishing jig 30 is arranged above the Y-axis motion module 107. Driven by the Y-axis motion module 107, the polishing jig 30 reciprocates between below the loading and unloading manipulator 20 and below the first polishing mechanism 50 or below the second polishing mechanism 40. In this embodiment, the Y-axis motion module 107 adopts a motor screw module, and the polishing jig 30 is driven to reciprocate by the motor screw module. Since the structure of the motor screw module belongs to a mature technical solution in the art, the structure thereof will not be described in detail in this embodiment.

[0050] For the loading and unloading manipulator 20, refer to Figure 4 、Figure 5 As shown in the figure, the present invention provides a specific embodiment. The loading and unloading manipulator 20 includes a support frame 204, a Y-axis drive module 201, a Z-axis drive module 202, and a suction cup module 203. The Y-axis drive module 201 is disposed above the support frame 204, and the Z-axis drive module 202 is installed on the Y-axis drive module 201; the suction cup module 203 includes a suction cup fixing frame and a plurality of suction cups evenly distributed on the suction cup fixing frame. The suction cup fixing frame is installed below the Z-axis drive module 202 and moves up and down driven by the Z-axis drive module 202; in this embodiment, the Z-axis drive module 202 adopts a motor screw module in the prior art, and its structure will not be described in detail in this embodiment.

[0051] In this embodiment, the Y-axis drive module 201 includes a manipulator cross beam 2011, a Y-axis motor 2012, a transmission rod 2013, a Y-axis slide rail 2014, and a Y-axis rack 2015. Two Y-axis slide rails 2014 are arranged side by side in the Y-axis direction. The Y-axis rack 2015 is parallel to the Y-axis slide rail 2014 and is located inside the Y-axis slide rail 2014; both ends of the manipulator cross beam 2011 are slidably installed on the Y-axis slide rail 2014 through sliding blocks; the Y-axis motor 2012 is installed on the side wall of the manipulator cross beam 2011. A driving wheel is installed on the motor shaft of the Y-axis motor 2012, and a driven wheel 2016 is installed on the transmission rod 2013. A transmission belt is sleeved between the driving wheel and the driven wheel 2016. Moreover, transmission gears 2017 are installed at both ends of the transmission rod 2013, and the transmission gears 2017 are engaged with the Y-axis rack 2015. With this structure, the Y-axis motor 2012 can drive the manipulator cross beam 2011 to translate on the Y-axis slide rail 2014; the above-mentioned Z-axis drive module 202 is fixedly installed on the manipulator cross beam 2011, thereby driving the suction cup module 203 to reciprocate and translate in the opposite direction of the Y-axis.

[0052] Combined with the above structure, we will explain the working principle of the high-efficiency polishing machine of the present invention. First, the workpiece to be processed is transferred to the loading transition tray 105. The Y-axis motion module 107 drives one of the polishing fixtures 30 to extend. The loading and unloading manipulator 20 transfers the workpiece to be processed from the loading transition tray 105 into the polishing fixture 30. After that, the polishing fixture 30 retracts below the first polishing mechanism 50 to polish the workpiece. At the same time, the loading and unloading manipulator 20 can transfer the workpiece in the loading transition tray 105 into the polishing fixture 30 located below the second polishing mechanism 40. At this time, the loading process is carried out simultaneously with the polishing process of the first polishing mechanism 50; during unloading, the Y-axis motion module 107 drives the polishing fixture 30 to extend. The loading and unloading manipulator 20 transfers the processed workpiece in the polishing fixture 30 into the unloading transition tray 106. At this time, the polishing process in the other polishing mechanism is not affected. Therefore, the present invention can realize the actions of loading, processing, and unloading without stopping the machine, improving the polishing efficiency.

[0053] In addition, it should be noted that two polishing jigs 30 are provided below both the first polishing mechanism 50 and the second polishing mechanism 40. When the workpiece in one of the two polishing jigs 30 is being polished, and the other polishing jig 30 needs to be loaded or unloaded, the corresponding polishing mechanism needs to stop briefly. For example Figure 3 in, the two polishing jigs 30 below the first polishing mechanism 50 perform polishing simultaneously. When the workpiece in the left polishing jig 30 is finished and needs to be unloaded, the first polishing mechanism 50 needs to stop, so that the left polishing jig 30 can extend for unloading. And when the left polishing jig 30 extends, the first polishing mechanism 50 can polish the right polishing jig 30 alone.

[0054] Regarding the specific structures of the first polishing mechanism 50 and the second polishing mechanism 40, since their structures are the same, in this embodiment, the structure of the first polishing mechanism 50 is taken as an example for detailed description. Refer to Figures 6 to 10 as shown, the first polishing mechanism includes a power component, a planetary power transmission component 505, a polishing wheel planet carrier 502, and a plurality of polishing discs 60; in this embodiment, the power component is the main motor 501, and the planetary power transmission component 505 is located between the main motor 501 and the polishing wheel planet carrier 502. The planetary power transmission component 505 is used to transmit the power of the main motor 501 to the polishing wheel planet carrier 502, driving the polishing wheel planet carrier 502 to rotate around its center, which is called revolution in this embodiment.

[0055] Furthermore, a plurality of polishing discs 60 are all rotatably installed on the polishing wheel planet carrier 502. In this embodiment, there are two groups of polishing wheel planet carriers 502, and three polishing discs 60 are evenly distributed on each group of polishing wheel planet carriers 502. When the two adjacent groups of polishing wheel planet carriers 502 are installed, the angles are adjusted so that the initial phase angles differ by 120°, so that the two groups of polishing wheel planet carriers can avoid interference during rotation. Combining Figures 8 to 10 as shown, an internally toothed ring 503 for self-rotation concentric with the polishing wheel planet carrier 502 is provided above the polishing wheel planet carrier 502, and the internally toothed ring 503 has internal teeth; a planetary shaft spur gear 504 meshing with the internally toothed ring 503 for self-rotation is provided on each polishing disc 60. Therefore, when the polishing disc 60 planet carrier makes a revolution, due to the meshing of the planetary shaft spur gear 504 with the internally toothed gear for self-rotation, the polishing disc 60 itself can also rotate, which is called self-rotation in this embodiment. Through this structure, under the driving force of the main motor 501, the polishing disc 60 not only revolves around the center of the polishing wheel planet carrier 502, but also rotates around its own center. When the polishing disc 60 polishes the workpiece, the polishing efficiency and grinding quality can be significantly improved.

[0056] In the above embodiments, a motor spur gear 5011 is installed on the motor shaft of the main motor 501. Regarding the specific structure of the planetary power transmission assembly 505, the present invention provides a specific embodiment, as follows Figure 9 , Figure 10 shown, the planetary power transmission assembly 505 includes a second large gear 5052, a shafted spur gear 5054, and a first large gear 5051; the second large gear 5052 is externally meshed with the motor spur gear 5011, the second large gear 5052 and the shafted spur gear 5054 are fixed on the same rotating shaft, and the first large gear 5051 is externally meshed with the shafted spur gear 5054; a first sun shaft 5055 is provided at the center of the polishing wheel planet carrier 502, and the first sun shaft 5055 is fixed at the center of the first large gear 5051.

[0057] In addition, since there are two sets of polishing wheel planet carriers 502 in this embodiment, for the driving force of the other set of polishing wheel planet carriers 502, on the basis of the above embodiments, the planetary power transmission assembly 505 further includes an intermediate gear 5056 and a third large gear 5053, and the intermediate gear 5056 is externally meshed with the shafted spur gear 5054, and the third large gear 5053 is externally meshed with the intermediate gear 5056; a second sun shaft 5057 is provided at the center of the other polishing wheel planet carrier 502, and the second sun shaft 5057 is fixed at the center of the third large gear 5053.

[0058] In the above structure, due to the existence of the intermediate gear 5056, the rotation directions of the two polishing wheel planet carriers 502 are exactly opposite. This design can avoid polishing a product in only one direction in the same area. Therefore, this design of the present invention can further improve the polishing effect. And in this embodiment, at a specific moment, the polishing disc 60 on one of the polishing wheel planet carriers 502 is just at the center of the connection line of the two polishing discs 60 on the other polishing wheel planet carrier 502. This design can not only avoid the problem of interference between the polishing discs 60, but also reduce the volume of the overall structure to a certain extent.

[0059] In the above embodiments, the first polishing mechanism further includes a lifting assembly, which includes a locking cylinder 5061, a guide post 5062, and a guide sleeve; the main motor 501 is fixedly installed on the motor mounting plate 5063, the motor mounting plate 5063 is fixed on the gear shaft mounting plate, and the gear shaft mounting plate is fixed on the polishing shaft mounting plate 5064. The above planetary power transmission assembly 505 is located inside the planetary shaft housing 5058 below the polishing shaft mounting plate 5064 and the polishing shaft mounting plate 5064. Further, the guide sleeve is fixedly installed at both ends of the polishing shaft mounting plate 5064, and the guide sleeve is slidably installed on the guide post 5062; the cylinder rod of the locking cylinder 5061 is connected to the polishing shaft mounting plate 5064 to drive the polishing shaft mounting plate 5064 to slide on the guide post 5062. In addition, a bearing 5065 is installed on the polishing wheel planet carrier 502, and a planetary polishing shaft 5066 is arranged inside the bearing 5065. The planetary shaft straight tooth 504 is fixed at the top end of the planetary polishing shaft 5066, and the polishing disc 60 is fixed at the bottom end of the planetary polishing shaft 5066.

[0060] For the specific structure of the polishing disc 60 in this embodiment, as Figures 11 to 14 shown, the present invention provides a specific embodiment. The polishing disc 60 includes a polishing wheel 601, a polishing disc body 602, and a plurality of polishing disc wave crest pressing strips 603; the polishing wheel 601 is in a frustum shape, and its bottom is connected to the polishing disc body 602. In this embodiment, screw holes 6011 are provided at corresponding positions of the polishing wheel 601 and the polishing disc body 602, and the polishing wheel 601 and the polishing disc body 602 are fixed to each other by screws. The polishing wheel 601 is used to be connected to a device that provides polishing power to drive the polishing wheel 601 to rotate, so as to realize the polishing action of the glass workpiece.

[0061] Further, the polishing disc body 602 is in a disc shape and has opposite sides. The polishing wheel 601 is fixed on one side of the polishing disc body 602, and the other side of the polishing disc body 602 is a polishing processing surface, and a plurality of polishing disc wave crest pressing strips 603 are distributed on the polishing processing surface; as Figure 13 shown, every two polishing disc wave crest pressing strips 603 form a group, and a total of six groups, that is, 12 polishing disc wave crest pressing strips 603 are distributed on the polishing processing surface, and each polishing disc wave crest pressing strip 603 is distributed roughly along the diameter direction of the polishing processing surface. In this embodiment, the polishing disc wave crest pressing strip 603 is in a cylindrical shape.

[0062] Combined with Figure 14As shown, a hole for accommodating a compression spring 604 is provided on the polishing disc body 602, and the bottom end of the compression spring 604 presses on the wave crest strip of the polishing disc; a cylindrical pin 605 for limiting the wave crest strip 603 of the polishing disc is further provided between the wave crest strip 603 of the polishing disc and the polishing disc body 602. In this embodiment, limiting holes for accommodating the cylindrical pin 605 are provided on both the polishing disc body 602 and the wave crest strip 603 of the polishing disc. The limiting hole on the wave crest strip 603 of the polishing disc is a blind hole, and the limiting hole on the polishing disc body 602 can be a through hole. With this structure, the wave crest strip 603 of the polishing disc can move axially on the polishing disc body 602. Due to the presence of the compression spring 604, an elastic connection is achieved between the wave crest strip 603 of the polishing disc and the polishing disc body 602.

[0063] In addition, an annular blanket strip 606 is sleeved on the polishing disc body 602. During the use of the polishing head of the present invention, a blanket is sleeved on the polishing surface of the polishing disc body 602, and the four sides of the blanket are tightened by the blanket strip 606. In this embodiment, the other side of the polishing disc body 602 extends outward to form a convex portion 6021 with a diameter larger than that of the polishing disc body 602, and the polishing surface is located on the surface of the convex portion 6021. The four sides of the blanket are pressed tightly between the convex portion 6021 and the blanket strip 606.

[0064] Combining the above structure, we will describe the working process of the polishing disc of the present invention in detail. First, a blanket is sleeved on the convex portion 6021 of the polishing disc body 602, and the four sides of the blanket are clamped between the blanket strip 606 and the convex portion 6021. The blanket wraps the entire polishing surface, and at the same time, the blanket plays a role in limiting the wave crest strip 603 of the polishing disc to prevent it from falling off the polishing disc body 602. When polishing a workpiece, the blanket contacts the surface of the workpiece. Due to the presence of the wave crest strip 603 of the polishing disc and the elastic connection between the wave crest strip 603 of the polishing disc and the polishing disc body 602, the acting force transmitted by the wave crest strip 603 of the polishing disc to the workpiece surface through the blanket is an elastic force. This kind of elastic force has different polishing forces for different positions. The wave crest strip 603 of the polishing disc automatically adjusts according to the uneven situation of the glass workpiece to achieve wave polishing; therefore, the size of the polishing force can be adjusted adaptively, thereby improving the polishing efficiency and polishing effect.

[0065] The above is a specific description of the preferred embodiment of the present invention, but the present invention is not limited to the described embodiment.
