[0049] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0050] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] like Figure 1-Figure 19 As shown, a polishing device for wooden furniture according to an embodiment of the present application is installed on a six-axis manipulator 4 through a multi-sided mounting table 5, the multi-sided mounting table 5 has a built-in motor, and the six-axis manipulator 4 is equipped with a conveying mechanism 2 for loading and unloading materials and a material fixing mechanism 3 for carrying materials on the periphery thereof, and the conveying mechanism 2, the material fixing mechanism 3 and the six-axis manipulator 4 are all arranged in a frame 1 for dust prevention.

[0052] It should be noted that in the specific embodiment of the present application, the multi-sided mounting table 5 is square in shape. Except for one side connected to the six-axis manipulator 4, the other five sides can be adapted to install a polishing device similar to the present application to meet different degrees of polishing requirements and improve polishing efficiency.

[0053] A polishing device for wooden furniture according to an embodiment of the present application includes: a driving mechanism 6 and a storage mechanism 7 .

[0054] Among them, Figure 5 As shown, the driving mechanism 6 includes a driving shaft 61 , which is key-connected to the output shaft of the motor. The driving mechanism 6 also includes a polishing wheel 62 coaxially fixed to the driving shaft 61 to realize the rotation of the polishing wheel 62 .

[0055] Further, such as Figure 5 As shown, the storage mechanism 7 includes a storage cylinder 71 sealed on the drive shaft 61, a throwing wheel 72 embedded in the bottom of the polishing wheel 62 and sealed and plugged with the storage cylinder 71, an extrusion assembly 73 fixedly connected to the multi-sided mounting table 5 and sealingly sliding in the storage cylinder 71, and a blocking assembly 74 fixedly connected to the bottom of the storage cylinder 71, the throwing wheel 72 is connected to the storage cylinder 71 and is fixed to the drive shaft 61; it can be understood that the drive shaft 61 drives the polishing wheel 62 to rotate, and utilizes the relationship between the throwing wheel 72 and the polishing wheel 62 and the storage cylinder 71 respectively, so as to realize the synchronous and unidirectional rotation between the polishing wheel 62, the storage cylinder 71 and the throwing wheel 72; through the fixed relationship between the extrusion assembly 73 and the multi-sided mounting table 5, it can be further understood that the relationship between the extrusion assembly 73 and the storage cylinder 71 is sealed, slidable and rotatable.

[0056] It should be noted that the storage cylinder 71 is used to store abrasive paste; the throwing wheel 72 is located at one end of the bottom side of the polishing wheel 62, and a channel for throwing the abrasive paste is opened on its side wall. It can be seen that the abrasive paste is eventually thrown from the side wall of the throwing wheel 72 to the polishing wheel 62.

[0057] In addition, a polishing device for wooden furniture according to an embodiment of the present application also has the following additional technical features:

[0058] like Figure 1 and Figure 2 As shown, the frame 1 includes a base 11 and a dust cover 12 fixedly connected to the base 11. Specifically, the frame 1 is also provided with a related control device. The specific control equipment, control system, control method and other related prior arts are already very mature and will not be repeated in the specific embodiments of the present application.

[0059] like Figure 3 As shown, the conveying mechanism 2 includes a feed conveying member 21 and a discharge conveying member 22 fixedly connected to the base 11. It should be noted that the feed conveying member 21 and the discharge conveying member 22 are both existing technologies and are used to convey materials that need to be polished and have been polished. The specific selection depends on actual needs and is not limited in the specific embodiments of this application.

[0060] like Figure 3As shown, the material fixing mechanism 3 includes a debris collection box 31 fixedly connected to the base 11, the debris collection box 31 is located on the discharge end side of the feed conveyor 21 and the feed end side of the discharge conveyor 22, the debris collection box 31 is externally connected to a dust suction device, and a jacking assembly 32 and a clamping assembly 33 are coaxially arranged in the debris collection box 31. It should be noted that in the specific embodiment of the present application, the jacking assembly 32 plays a role in adjusting the height of the polished material, and the clamping assembly 33 plays a role in fixing the polished material. The specific structure is not required in the specific embodiment of the present application, and both are already very mature in the prior art. The specific selection is determined according to actual needs and is not limited here.

[0061] like Figure 6 and Figure 7 As shown, the polishing wheel 62 consists of a fixing part and a polishing part. The fixing part of the polishing wheel 62 is coaxially fixed to the upper end of the polishing part of the polishing wheel 62. A plurality of first through holes 621 are coaxially arranged on the fixing part of the polishing wheel 62. The plurality of first through holes 621 are evenly arranged circumferentially.

[0062] Further, such as Figure 6 , Figure 8 and Fig. 9 As shown, the top of the storage cylinder 71 is open, and the storage cylinder 71 includes an outer cylinder wall 711 and an inner cylinder wall 712 which are coaxially arranged. The height of the outer cylinder wall 711 is smaller than the height of the inner cylinder wall 712. The inner cylinder wall 712 is slidably sleeved on the drive shaft 61. A plurality of discharge holes 713 are evenly arranged circumferentially at the bottom end of the storage cylinder 71.

[0063] It should be noted that the design that the height of the inner cylinder wall 712 is greater than that of the outer cylinder wall 711 facilitates the abutment between the storage cylinder 71 and the multi-sided mounting platform 5 during the installation process, and cooperates with the ejection wheel 72 at one end of the drive shaft 61 away from the multi-sided mounting platform 5 to position the storage cylinder 71 on the drive shaft 61.

[0064] like Figure 6 , Figure 10-13As shown, the throwing wheel 72 includes a wheel disc 721 and a plurality of wheel posts 722. The wheel disc 721 is embedded in the polishing wheel 62. It should be noted that the wheel disc 721 is embedded in the polishing wheel 62 so that the thrown abrasive paste first touches the polishing wheel 62 and will not be thrown out of the polishing wheel 62; the plurality of wheel posts 722 are evenly fixed to the wheel disc 721 in the circumferential direction, and penetrate the plurality of first through holes 621 and are sealed and slidably connected to the plurality of discharge holes 713 one by one. It should be noted that the wheel disc 721 and the polishing wheel 62 can be sequentially penetrated and fixed to the end surface of the driving shaft 61 by bolts and other related fixing parts; the wheel post 722 is plugged into At one end of the storage tube 71, an inlet 723 is provided on its side wall. It should be noted that in the specific embodiment of the present application, the inlet 723 is preferably oriented toward the side away from the axis to facilitate the entry of the abrasive paste after being squeezed; a plurality of discharge channels 724 arranged radially are evenly arranged circumferentially inside the wheel disc 721 to achieve uniform distribution of the abrasive paste; an annular cavity 725 is coaxially arranged inside the wheel disc 721, and the annular cavity 725 is respectively connected to the plurality of inlets 723 and the plurality of discharge channels 724, so that a complete flow channel is formed for the abrasive paste from the storage tube 71 to the side wall of the throwing wheel 72.

[0065] Further, such as Fig.12 and Fig.13 As shown, the discharge channel 724 is arranged in an arc shape, and the discharge end of the discharge channel 724 is arranged on the side wall of the throwing wheel 72 and is inclined downward. The arc-shaped discharge channel 724 can reduce the force of the abrasive paste to be thrown out by the centrifugal force generated by the throwing wheel 72 during the rotation to a certain extent. In conjunction with the annular cavity 725, the abrasive paste can to a certain extent be uniformly introduced into each discharge channel 724 and then thrown out. The discharge end of the discharge channel 724 which is inclined downward can to a certain extent make the abrasive paste be thrown toward the end of the inner wall of the polishing wheel 62 close to the surface of the polished object when being thrown out, thereby avoiding the formation of residual abrasive paste on the inner wall of the polishing wheel 62.

[0066] Further, such as Figure 5 and Fig.14 As shown, the extrusion assembly 73 includes a telescopic member 731 and a sealing piston 732. The telescopic member 731 is fixed to the multi-sided mounting platform 5; the sealing piston 732 slides in a sealing manner in the storage cylinder 71 and is fixed to the telescopic end of the telescopic member 731; the bottom end of the sealing piston 732 is coaxially provided with a recessed portion 733.

[0067] It should be noted that, in the specific embodiment of the present application, the telescopic member 731 is preferably an electric push rod to reduce the number of cables and pipes on the outside of the multi-sided mounting platform 5 to make its appearance simple.

[0068] like Figure 5 , Figure 8 and Fig.15As shown, the sealing assembly 74 includes an annular chamber 741, a sealing spring 742 and a sealing piston 743. The annular chamber 741 is fixedly sleeved on the inner cylinder wall 712. The outer diameter of the annular chamber 741 is smaller than the inner diameter of the recessed portion 733. It can be understood that when the extrusion assembly 73 is displaced to the bottom end of the storage cylinder 71, the existence of the recessed portion 733 can make the sealing assembly 74 accommodated in the sealing piston 732, so that the grinding paste in the storage cylinder 71 can be discharged as cleanly as possible, the residual amount can be reduced, and the utilization rate of the grinding paste can be improved; the sealing spring 742 is coaxially arranged in the annular chamber 741 ... The cross-section of the plug 743 is an annular I-shape, and one end of the sealing piston 743 seals and slides on the annular chamber 741 and abuts against the sealing spring 742, and the other end thereof extends out of the annular chamber 741 and covers a plurality of discharge holes 713. It can be seen that when the ejection wheel 72 is inserted into the storage tube 71, the sealing piston 743 will be squeezed into the annular chamber 741, and when the ejection wheel 72 is separated from the storage tube 71, the sealing spring 742 can reset the sealing piston 743 and cover the plurality of discharge holes 713 to form a seal, thereby preventing leakage of the grinding paste in the storage tube 71.

[0069] The following describes the use process of a polishing device for wooden furniture according to an embodiment of the present application with reference to the accompanying drawings:

[0070] When in use, after the abrasive paste is filled into the storage cylinder 71, the telescopic end of the telescopic member 731 is in a contracted state, and then the wooden furniture to be polished (it should be noted that in the specific embodiment of the present application, if the rack 1 and other related accessories are used, then it is for the detachable small parts of the furniture. If the rack 1 and other related accessories are not used, and only the six-axis manipulator 4 is used, then it can be for partially formed furniture. The specific size of the polishing object depends on the actual operation, and the subsequent description in this application will not be repeated) is transported to the debris collection box 31 by the feed conveyor 21, and the jacking assembly 32 and the clamping assembly 33 are used to position the polished object, and then the six-axis manipulator 4 and the multi-faceted mounting table 5 are used to adjust the position and angle of the polishing device in the embodiment of the present application, and the built-in motor of the multi-faceted mounting table 5 drives the drive shaft 61 to rotate, so that the polishing wheel 62, the storage cylinder 71, the throwing wheel 72, and the blocking assembly 74 all achieve synchronous and unidirectional rotation. At this time, the sealing piston 732 and the storage cylinder 71 are in a sealed rotation relationship, and the use of The elongation change of the telescopic end of the telescopic member 731 forces the sealing piston 732 to gradually approach the sealing component 74 axially inside the storage tube 71, thereby squeezing the abrasive paste in the storage tube 71, so that the abrasive paste enters from the inlet 723 where the wheel column 722 is inserted into the storage tube 71, and enters the annular cavity 725, and then disperses to multiple discharge channels 724, and finally, under the action of the extrusion force and the centrifugal force, is thrown out from the discharge end of the discharge channel 724 which is arranged on the side wall of the wheel disc 721 and is inclined downward, and falls onto the surface of the polished object after touching the bottom end of the inner wall of the polishing wheel 62. As the polishing wheel 62 rotates and moves on the surface of the polished object, the abrasive paste is finally between the rotating polishing wheel 62 and the polished object. This design can realize the continuous polishing action of the polishing wheel 62 on the polished object, and can realize the control of the amount of the abrasive paste at any time, so as to avoid the insufficient amount of the abrasive paste caused by directly applying it or the waste caused by dipping, thereby improving the utilization rate of the abrasive paste and the efficiency of the entire polishing work.

[0071] In the related art, in the specific polishing work, the polishing device for wooden furniture adopts a continuous polishing operation, and the continuous rotation of the polishing wheel 62 on the surface of the polished object will cause the polishing wheel 62 to generate a certain amount of heat. In particular, when the polishing wheel 62 is fixed and rotated at a local location on the surface of the polished object for a relatively long time, the temperature between the polishing wheel 62 and the surface of the polished object will rise due to friction. Once the temperature reaches a certain range, it will cause the surface of the polished object to appear "orange peel".

[0072] According to some embodiments of the present application, Figure 4 , Figure 5 as well as Figure 16-18As shown, a guide mechanism 8 is coaxially arranged between the polishing wheel 62 and the storage cylinder 71 , and the guide mechanism 8 includes an upper guide ring 81 , a lower guide ring 82 and a plurality of guide plates 83 .

[0073] Specifically, the upper guide ring 81 is coaxially sleeved on the drive shaft 61, and the cross-section of the upper guide ring 81 is an arc-shaped setting that is concave downward; the lower guide ring 82 is coaxially sleeved on the drive shaft 61, and the cross-section of the lower guide ring 82 is an arc-shaped setting that is concave downward; a plurality of guide vanes 83 are coaxially fixed between the upper guide ring 81 and the lower guide ring 82, and the plurality of guide vanes 83 are evenly arranged circumferentially, and the guide vanes 83 are arranged in an arc shape.

[0074] It can be understood that the upper guide ring 81, the plurality of guide plates 83 and the lower guide ring 82 are composed as follows: Fig.16 and Fig.18 The overall downwardly recessed structure shown is convenient for installation between the polishing wheel 62 and the storage tube 71, and the synchronous rotation of the upper guide ring 81, multiple guide plates 83 and the lower guide ring 82 is realized by the rotation of the driving shaft 61, so that the upper guide ring 81, multiple guide plates 83 and the lower guide ring 82 generate airflow from their circumference to the axis during rotation.

[0075] It should be noted that the orientation of the plurality of guide vanes 83 between the upper guide ring 81 and the lower guide ring 82 is not along the radial direction, but forms a certain angle with the radial direction, so as to form airflow during the rotation process.

[0076] Among them, multiple groups of first air guide holes 622 are coaxially arranged on the outer side of the first through holes 621 that are evenly arranged circumferentially. The multiple groups of first air guide holes 622 are evenly arranged circumferentially, and each group of first air guide holes 622 is composed of multiple first air guide holes 622 distributed along an arc shape; multiple exhaust holes 623 are evenly arranged on the outer side of the multiple groups of first air guide holes 622 that are evenly arranged circumferentially, so as to facilitate the airflow to be discharged from the inner side of the polishing wheel 62.

[0077] Specifically, the wheel disc 721 is provided with a plurality of second air guide holes 726 corresponding one-to-one to the first through holes 621 , and the plurality of second air guide holes 726 are evenly arranged in the circumferential direction of the outer sides of the plurality of wheel posts 722 .

[0078] Furthermore, the lower guide ring 82 is provided with a plurality of third air guide holes 821 which correspond one-to-one to the first through holes 621 and the second air guide holes 726 and are interconnected.

[0079] Furthermore, a plurality of axially penetrating second through holes 84 are respectively provided on the upper guide ring 81 and the lower guide ring 82 . The plurality of second through holes 84 correspond one to one with the plurality of first through holes 621 and the plurality of wheel columns 722 , and the second through holes 84 and the wheel columns 722 are sealed and plugged together.

[0080] Furthermore, there is a guide cavity 85 between the upper guide ring 81 and the lower guide ring 82. The guide cavity 85 includes a gradient cavity 851 and a flow equalizing cavity 852. The cross-section of the gradient cavity 851 is arc-shaped, and it is gradually converged from the side away from the axis to the side close to the axis. It can be understood that after the airflow enters the guide cavity 85 from the peripheral side of the upper guide ring 81 and the lower guide ring 82, it is accelerated due to the reduction in space; the flow equalizing cavity 852 is annular and connected to the converged end of the gradient cavity 851; the third air guide hole 821 is arranged in the flow equalizing cavity 852. It can be seen that after the accelerated airflow enters the flow equalizing cavity 852, it will be discharged to the inner bottom side of the polishing wheel 62 through multiple third air guide holes 821.

[0081] Therefore, when the driving shaft 61 drives the polishing wheel 62 to rotate, the wheel column 722 passes through the second through hole 84, so that the guide mechanism 8 can rotate on the driving shaft 61 along with the driving shaft 61. Since the overall structure of the guide mechanism 8 is designed to be an arc that is concave downward, and a plurality of guide plates 83 that are arranged in an arc shape and have a certain angle with the radial direction are fixedly connected thereto, an airflow will be formed from the peripheral side during the rotation process, and after entering through the gradual cavity 851, it will be accelerated due to the gradual reduction of the space, and will be merged into the equalizing cavity 852 and finally flow out from the equalizing cavity 852. A downward airflow is formed at the multiple third air guide holes 821 in the flow cavity 852, blowing toward the surface of the polished object, and discharged from the multiple exhaust holes 623 uniformly arranged circumferentially on the outer side of the first air guide hole 622. The heat generated in the polishing part is continuously discharged from the exhaust holes 623 by utilizing the airflow continuously flowing in from the outside, which plays a role in dissipating the heat generated by friction during the polishing work, reduces the temperature increase, alleviates the temperature increase of the polishing wheel 62 and between the polishing wheel 62 and the surface of the polished object to a certain extent, and can reduce the occurrence of the "orange peel" phenomenon to a certain extent.

[0082] In the related art, in the process of squeezing the abrasive paste from the storage tube 71, a recessed portion 733 is provided on the bottom side of the sealing piston 732 to cover the sealing component 74 during the process of squeezing the abrasive paste so as to squeeze out as much of the abrasive paste in the storage tube 71 as possible. However, the volume of the recessed portion 733 must be set larger than the volume of the sealing component 74. If the sizes of the two are just right, then during the process of squeezing the abrasive paste, the sealing piston 732 will move to a certain position within the range of the sealing component 74. The pressure generated by the remaining space between the sealing component 74 and the sealing piston 732 will make it difficult for the sealing piston 732 to continue to move axially downward, which will result in a certain amount of abrasive paste remaining between the two.

[0083] According to some embodiments of the present application, Figure 5 and Fig.19As shown, an elastic component 9 is arranged in the recessed portion 733, and the elastic component 9 includes a discharge piston 91, a guide rod 92 and a discharge spring 93. The discharge piston 91 seals and slides in the recessed portion 733, and seals and slides with the inner cylinder wall 712; a plurality of guide rods 92 are evenly arranged circumferentially, and are slidably inserted in the sealing piston 732; a plurality of discharge springs 93 and a plurality of guide rods 92 are set one by one, and are located between the discharge piston 91 and the sealing piston 732.

[0084] The axial depth of the recessed portion 733 is greater than the axial height of the blocking assembly 74 . It is understandable that this design will provide accommodation space for the discharge piston 91 and the discharge spring 93 after being squeezed.

[0085] It should be noted that the elastic force value of the discharge spring 93 is set to be greater than the reaction force that the discharge piston 91 is subjected to when normally squeezing the grinding paste, that is, it can ensure that the discharge piston 91 is located on the bottom side of the sealing piston 732 before contacting the top of the sealing assembly 74.

[0086] The cam 732 is pressed against the top of the sealing member 74 so that the sealing member 732 is pressed against the bottom of the sealing member 74. Gradually insert it first into the recessed portion 733), during this process, the discharge piston 91 keeps in contact with the top of the sealing component 74, and the discharge spring 93 will be gradually compressed, and the guide rod 92 gradually extends from the top of the sealing piston 732 until the bottom of the sealing piston 732 touches the inner bottom of the storage cylinder 71. This design can achieve the complete discharge of the abrasive paste in the storage cylinder 71 and reduce the residual amount, and when the sealing piston 732 moves in the reverse direction, the elastic action of the discharge spring 93 will force the discharge piston 91 to gradually reset, so that the abrasive paste can be completely discharged when the sealing piston 732 moves downward next time.

[0087] It should be noted that the specific models and specifications of the feed conveyor 21, the discharge conveyor 22, the lifting assembly 32, the clamping assembly 33, the six-axis manipulator 4, the drive shaft 61, the telescopic member 731, the blocking spring 742 and the discharge spring 93 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0088] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
