[0049] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0051] When an element is referred to as being “fixed to” or “disposed on” or “provided on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0052] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances. Example

[0053] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present embodiment provides a polishing machine, including a turntable 10, a polishing mechanism 20, a wax supply unit 30 and a controller. The turntable 10 is provided with a loading and unloading station 101 and a plurality of processing stations 102, and the processing station 102 is provided with at least one fixture 103; the polishing mechanism 20 is provided with a plurality of groups, and a polishing mechanism 20 is arranged opposite to a processing station 102; the polishing mechanism 20 includes a cross slide rail 201, a vertical slide rail 202 arranged on the cross slide rail 201 and a polishing unit 203 arranged on the vertical slide rail 202, and the polishing unit 203 is used for polishing and polishing the workpiece on the fixture 103; the plurality of processing stations perform different processes or disassemble the same process into a plurality of sub-processes; the turntable 10, the polishing mechanism 20 and the wax supply unit 30 are electrically connected to the controller.

[0054] In this embodiment, the controller may be an operating platform or a computer, etc., so that the turntable 10, the grinding mechanism 20 and the wax supply unit 30 can be automatically coordinated for polishing, thereby achieving the purpose of automated assembly line processing, which is beneficial to improving production efficiency.

[0055] Specifically, a corresponding number of processing stations 102 are designed on the turntable 10 as required. For example, if three processes are required to complete the polishing and grinding operation, three processing stations 102 and one loading and unloading station 101 can be designed on the processing station 102. In addition, the number of polishing mechanisms 20 can be designed according to the space size of the factory. For example, two clamps 103 can be set on each processing station 102, so that each processing station 102 has two light clearing units 203 for matching, which can further improve the efficiency of polishing.

[0056] Alternatively, the same process can be processed by multiple stations. For example, a workpiece polishing process takes 90 seconds, and each process takes 30 seconds at three stations. Ignoring the rotation time of the turntable 10, the operator standing at the station 101 can complete the loading and unloading of a workpiece within 30 seconds, and the operation waiting time is 30 seconds, thus improving the processing efficiency.

[0057] Therefore, when the controller is configured to control multiple processing stations 102 to execute several sub-processes of the same process, at this time, the controller directly imports the processing process of the workpiece to process the workpiece.

[0058] When multiple processing stations 102 perform different processes, the controller calls the processing program of the workpiece to calculate the longest processing time in different processes, and calls the loading and unloading time of the workpiece. When the longest processing time is less than or equal to the loading and unloading time of the workpiece, the processing program is imported for processing, and a reminder is output when the longest processing time is greater than the unloading time of the workpiece. It is easy to understand that in the set workpiece processing program, the grinding mechanism feed speed, feed distance, retracting speed, etc. are set, so that the processing time of the corresponding process can be calculated; by counting the clamping and removal time of the workpiece, the average loading and unloading time of the workpiece (that is, the time for the operator to complete the clamping of a workpiece and the removal of a workpiece) can be calculated. Therefore, when the longest processing time is greater than the unloading time of the workpiece, it means that the operator has a long waiting time for the operation. At this time, a reminder is output to adjust the processing parameters of the processing program according to actual needs, or use multiple stations of the polishing machine to decompose the working hours of the longer process time to reduce the operator's waiting time for the operation.

[0059] In a preferred embodiment, when comparing the longest processing step time with the workpiece loading and unloading time, a threshold greater than 1 can be assigned to the workpiece loading and unloading time. On the one hand, this ensures that the operator has sufficient time to work. On the other hand, when the longest processing step time is too close to the workpiece loading and unloading time, based on economic considerations (disassembling the process, it may be necessary to introduce other polishing machines to complete other processes), no reminder is output at this time; the threshold value range can be set according to demand.

[0060] When in use, at the loading and unloading station 101, the workpiece to be polished is clamped on the fixture 103 (the fixture 103 can be a clamping claw, a carrier plate or a special fixture, etc., and can be fixed by magnetic attraction, vacuum attraction, clamping, groove limiting, etc., so as to achieve the purpose of fixing the workpiece). The turntable 10 is rotated to remove the polished workpiece on the loading and unloading station 101, and reinstall the workpiece to be polished; and the corresponding polishing process is performed on the processing station 102, for example, the first processing station 102 performs rough polishing, the second processing station 102 performs the first fine polishing; the third processing station 102 performs the second fine polishing, so as to complete the purpose of polishing the workpiece and achieve the assembly line type efficient polishing operation.

[0061] Furthermore, each polishing unit 203 (for example, polishing by driving a grinding wheel to rotate through a motor) can form a three-dimensional position adjustment effect through the design of the cross rail 201 and the vertical rail 202 to meet the polishing of most products, with high polishing flexibility and improved practicality. At the same time, the turntable can also rotate to cooperate with the grinding wheel for polishing and grinding, so as to adapt to the polishing effect of different products and improve the adaptability of polishing.

[0062] like Figure 5 and Figure 6 As shown, the present embodiment also includes a wax supply unit 30 disposed on the housing of the clearing unit 203, and the wax supply unit 30 is used to supply wax to the polishing wheel 2032 of the clearing unit 203; the wax supply unit 30 includes a wax discharge tube 301, a power unit 302 that drives the wax discharge tube 301 toward or away from the polishing wheel 2032, a clamping member 303 that fixes the wax block in the wax discharge tube 301, and an adjusting unit 304 that blocks the wax block at the outlet of the wax discharge tube 301; a fixing frame 3025 of the power unit 302 is disposed on the housing of the clearing unit 203, the clamping member 303 and the adjusting unit 304 are disposed on the fixing frame 3025, and the wax discharge tube 301 is tilted from top to bottom.

[0063] Specifically, the operation of polishing and waxing is used to improve the glossiness of the polished surface and also to provide corresponding wax surface protection. However, the amount of wax supplied directly affects the polishing effect and the cost of the wax material. At the same time, how to supply wax is related to safety performance.

[0064] like Figure 5 and Figure 6 As shown, in this embodiment, a long wax block is placed in the wax tube 301, and the inclined wax tube 301 will make the wax block slide in the wax tube 301 by its own weight. Therefore, an adjustment unit 304 is provided at the exit position of the wax tube 301 to prevent the wax block from falling out of the wax tube 301 and limit the length of the wax block extending out of the wax tube 301. Then, the wax block in the wax tube 301 is clamped by the clamping member 303, so that after the adjustment unit 304 is removed, the extended end surface of the wax block can be contacted by the polishing wheel 2032 for wax supply; at the same time, the clamping and fixing of the clamping frame can also prevent the wax block from falling out of the wax tube 301. Therefore, the power unit 302 is started to drive the wax tube 301 to move, so that the wax block after adjustment and fixing contacts or separates with the polishing wheel 2032, so as to achieve the purpose of wax supply through the device.

[0065] Furthermore, the clamping position of the clamping member 303 can be designed at the outlet of the wax discharge tube 301, so that the wax block can be effectively clamped for use, the remaining amount of the wax block after use can be reduced, the waste of wax blocks can be avoided, and the production cost can be reduced.

[0066] Furthermore, if Figure 5 and Figure 6 As shown, the power unit 302 in this embodiment includes a rack 3021 axially arranged on the wax discharge tube 301, a wax supply motor 3022 that drives the rack 3021 to move, and a guide rod 3023 with end plates at both ends arranged on the wax discharge tube 301, a guide plate 3024 that slides with the guide rod 3023 is arranged in the middle of the guide rod 3023, and the guide plate 3024 is arranged on the fixed frame 3025 of the power unit 302.

[0067] Specifically, the wax supply motor 3022 can be a reduction motor or a servo motor, and a gear is installed on the output shaft of the wax supply motor 3022 to mesh with the rack 3021, and the guide rod 3023 is designed to drive the wax discharge tube 301 to move through the wax supply motor 3022, that is, the wax discharge tube 301 moves toward or away from the polishing wheel 2032. The purpose of driving the wax discharge tube 301 to move stably is achieved.

[0068] Furthermore, if Figure 6 and Figure 8 As shown, in this embodiment, the adjustment unit 304 includes an adjustment cylinder 3041 (for example, a single-axis cylinder) and a blocking rod 3042 arranged on the output shaft of the adjustment cylinder 3041, and a wax outlet gap is arranged between the blocking rod 3042 and the outlet of the wax discharge tube 301. The wax outlet gap can be adjusted according to the power of the polishing wheel 2032, so that the adjustment cylinder 3041 only needs to be operated to drive the blocking rod 3042 to move and block, so as to achieve the purpose of blocking the wax block.

[0069] Furthermore, if Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, the clamping member 303 is symmetrically provided with two clamping claws 3030 with the wax discharge tube 301 as a center; the clamping claw 3030 includes a mounting plate 3031 arranged on the fixing frame 3025, a swing rod 3032 swing-hingedly installed on the mounting plate 3031, and a swing cylinder 3033 arranged on one end of the swing rod 3032, a clamping block 3034 is arranged on the other end of the swing rod 3032, and a first opening 3011 opposite to the clamping block 3034 is arranged on the side of the outlet pipe section of the wax discharge tube 301.

[0070] Specifically, through the structure of the seesaw, the swing rod 3032 is installed on the mounting plate 3031. The swing cylinder 3033 provides power to drive the swing rod 3032 to swing, so that the clamping block 3034 on the other end of the swing rod 3032 passes through the first opening 3011 and clamps and abuts against the wax block. In this way, the purpose of clamping the two sides of the wax block by the two clamping claws 3030 is achieved.

[0071] like Figure 7 and Figure 8 As shown, the present embodiment also includes a push unit 305, which includes a push rod 3051 swingably set on the bottom surface of the wax discharge tube 301 and a push cylinder 3052 driving the push rod 3051 to swing, a push block 3053 is set on the end of the push rod 3051 away from the push cylinder 3052, and a second opening 3012 opposite to the push block 3053 is set on the bottom surface outlet section of the wax discharge tube 301.

[0072] Specifically, in order to improve the stability of the wax block during the wax supply process, a top block 3053 is also used to push against the bottom surface, so that the wax block can be clamped and fixed on all four sides in cooperation with the top plate of the wax tube 301 and the two clamping claws 3030. Specifically, the top rod 3051 is driven to swing by the top pressure cylinder 3052, so that the top block 3053 on the other end of the top rod 3051 passes through the second opening 3012 and pushes against the wax block, thus achieving the purpose of pushing against the bottom surface and improving the stability of clamping.

[0073] Furthermore, if Figure 7 , Figure 8 and Fig. 9 As shown, in this embodiment, the supporting unit 305 also includes a tilting rod 3054 swingably set on the bottom surface of the wax placing tube 301, the tilting rod 3054 and the swing rod 3032 are arranged side by side, and a supporting protrusion 3055 is provided on one end of the tilting rod 3054 for supporting against the arc surface of the wax block; the weight of the tilting rod 3054 from the swing fulcrum to the other end is greater than the weight from the swing fulcrum to the end with the supporting protrusion 3055.

[0074] Specifically, the design of the tilting rod 3054 can keep the support protrusion 3055 against the wax block, and the arc surface design of the top surface of the support protrusion 3055 can make the contact surface of the front end of the wax block smaller, so that the wax block can slide in the wax supply tube, that is, the friction of the wax block in the wax discharge tube 301 is reduced, which is conducive to the sliding of the wax block by its own weight.

[0075] like Figure 3 and Figure 4 As shown, in this embodiment, the polishing unit 203 includes a power frame 2031 disposed on a slider of a vertical slide rail 202, a polishing wheel 2032 disposed on one end of the power frame 2031, and a polishing motor 2033 disposed on the other end of the power frame 2031 and driving the polishing wheel 2032 to rotate. The polishing motor 2033 can be a servo motor, and can use a pulley, gear or chain to drive the polishing wheel 2032 to rotate. With such a design, the polishing wheel 2032 can be extended out of the power frame 2031 to polish the workpiece.

[0076] Furthermore, if Figure 4 As shown, in this embodiment, an arc cover 2034 for mounting a polishing wheel 2032 is provided on one end of the power frame 2031, and a dustproof bin 2035 is provided between the central axis of the polishing wheel 2032 and the output shaft of the grinding motor 2033. The design of the arc cover 2034 can prevent the polishing dust from scattering, effectively control the dust in a certain area, and improve the practicality. The design of the dustproof bin 2035 can ensure the stable operation of the polishing wheel 2032, avoid the accumulation of dust in the power transmission mechanism, and improve the stability and safety of the equipment operation.

[0077] like Figure 1 and Figure 2 As shown, this embodiment also includes a base 40 with a horizontal top surface, and the turntable 10 and the grinding mechanism 20 are arranged on the top surface of the base 40. The design of the base 40 can provide a relatively horizontal base to provide a precise grinding accuracy, and at the same time facilitate the assembly of the polishing machine and improve practicality.

[0078] The present invention also discloses a workpiece polishing method, which utilizes the aforementioned polishing machine to polish the workpiece, and the process will not be described in detail here.

[0079] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
