DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0035] like Figures 1 to 10 As shown, the surface polishing device for door and window handles of the present invention comprises a conveying mechanism 1, a polishing device 2 and a mechanical arm 3. The conveying mechanism 1 is used to convey the handle 4 to be polished to the gripping range of the mechanical arm 3, and then the mechanical arm 3 grips the handle 4 on the conveying mechanism 1, and then polishes it on the polishing wheel 5 and the polishing belt 6 on the polishing device 2 according to the actual polishing operation, so as to realize the automatic operation.

[0036] The conveying mechanism 1 is provided with a conveyor belt 7 and a plurality of retaining components 8 arranged on the conveyor belt 7. The conveyor belt 7 can be arranged in a circular runway shape, so that the staff or the mechanical arm 3 can clamp the handle 4 to be polished and place it on the conveyor belt 7, and then limit it through the retaining components 8. The retaining components 8 are used to maintain the stability of the handle 4 placed on the conveyor belt 7.

[0037] In actual production, a guide plate (not shown in the figure) can be provided at the upper end of the conveyor belt 7. The guide plate is provided at the position where the handle 4 is placed and taken for polishing. One end of the guide plate is kept higher and the other end is kept lower, so that the guide plate is set at an angle. The conveyor belt 7 moves from the higher end of the guide plate to the lower end, so that the retaining member 19 in the retaining assembly 8 can be pressed by the guide plate, so that the pressure member 9 is compressed, and the end that is kept away from the pressure member 9 is lifted, which is convenient for the staff or the robot arm 3 to place the handle 4 that needs to be polished on the conveyor belt 7. By providing a guide plate, when the conveyor belt 7 drives the retaining assembly 8 to the staff or the two robot arms 3, one end of the retaining member 19 can be automatically pressed and lifted, so as to facilitate the placement or removal of the handle 4 that needs to be polished or the handle 4 that has been polished, realize the automated polishing operation, improve the polishing efficiency, and reduce the labor intensity of the staff.

[0038] The polishing device 2 is used to polish the handle 4 on the conveying mechanism 1. The polishing device 2 is provided with a polishing table 10. The polishing table 10 is provided with a polishing motor 11. A transmission shaft 12 is provided in the middle of the polishing motor 11. Both ends of the transmission shaft 12 extend from the polishing motor 11. A polishing wheel 5 is provided at one end of the transmission shaft 12, and a driving wheel 13 is provided at the other end. A driven wheel 14 is also provided on the polishing table 10. A polishing belt 6 is provided on the driving wheel 13 and the driven wheel 14. A housing 15 is provided outside the polishing belt 6. A driving cylinder 16 is provided on the polishing table 10, and the driving cylinder 16 can adjust the tightness of the polishing belt 6.

[0039] A first collecting bin 17 and a second collecting bin 18 are also provided on the polishing table 10 . The first collecting bin 17 is arranged at the lower end of the polishing wheel 5 , and the second collecting bin 18 is arranged at the lower end of the polishing belt 6 , for collecting dust particles after the handle 4 is polished.

[0040] The robot arm 3 is used to clamp the handle 4 on the conveying mechanism 1. The robot arm 3 clamps the handle 4 on the conveyor belt 7 and transfers it to the polishing device 2 for polishing.

[0041] The retaining assembly 8 includes a retaining member 19 and a limiting member 20. The retaining member 19 is arranged on the conveyor belt 7, and the limiting member 20 is installed at one end of the retaining member 19. The limiting member 20 is brought into contact with the handle 4 by changing the angle of the retaining member 19, so that the handle 4 is restricted on the conveyor belt 7 by friction, and the handle 4 is kept from tilting or loosening during the movement of the conveyor belt 7, which can improve the accuracy of the robot arm 3 in clamping the handle 4 and reduce erroneous operations.

[0042] The retaining member 19 is arranged on the conveyor belt 7. When the retaining member 19 is installed, it is rotated to be installed on the conveyor belt 7. The lower end of the retaining member 19 is provided with a supporting member 28 and a pressing member 9. The supporting member 28 restricts the retaining member 19 on the conveyor belt 7. The pressing member 9 is arranged at one end of the retaining member 19, and the end with the pressing member 9 is pushed upward, and the other end is kept to be pressed downward.

[0043] The retaining member 19 is composed of a pushing section 21 and a pressure section 22. The pushing section 21 is arranged horizontally, and the pressure section 22 is arranged obliquely. The angle between the pushing section 21 and the pressure section 22 is 145°. When the pushing section 21 is subjected to force, the pressure section 22 can be kept in contact with the handle 4, and friction is generated between the handle 4 to limit the position of the handle 4. This can ensure that the handle 4 will not be offset during the movement of the conveyor belt 7, and can also limit the position of the handle 4 without causing damage to the surface of the handle 4, thereby improving the qualified rate of the handle 4.

[0044] A counterweight block 23 is provided on the pushing section 21 , and the counterweight block 23 is used to apply pressure to the pressure member 9 at the lower end of the pressure section 22 .

[0045] The length of the push section 21 is 1 / 3 of the length of the entire retainer 19, and the length of the pressure section 22 is 2 / 3 of the length of the entire retainer 19. To ensure that the hinge column 24 is at 1 / 3 of the entire retainer 19, the push section 21 is shorter and the pressure section 22 is longer, so that the retainer 19 can better limit the position of the handle 4.

[0046] An extension section 25 is provided at the lower end of the connection between the pushing section 21 and the pressure section 22 . A hinge column 24 is provided at the lower end of the extension section 25 . The hinge column 24 and the extension section 25 are vertically arranged. The support member 28 is sleeved on the extension section 25 .

[0047] The conveyor belt 7 is provided with a through slot 26 that matches the hinge column 24, and the lower end of the through slot 26 is provided with a hinge arc slot 27 that is perpendicular to the through slot 26. The hinge column 24 reaches the lower end of the conveyor belt 7 through the through slot 26, and after the retainer 19 is rotated, the hinge column 24 is placed in the hinge arc slot 27.

[0048] A first positioning hole 41 is provided at the lower end of the pushing section 22 , and a second positioning hole 42 is provided on the conveyor belt 7 . The second positioning hole 42 is arranged just below the first positioning hole 41 . The upper end of the pressure member 9 is arranged in the first positioning hole 41 , and the lower end is arranged in the second positioning hole 42 .

[0049] like Fig.10As shown, the hinge column 24 at the lower end of the retainer 19 is arranged parallel to the through slot 26, and the size of the through slot 26 matches the hinge column 24, so that the hinge column 24 can be directly placed in the through slot 26. When the retainer 19 has not been installed in the through slot 26, the lower end of the support member 28 acts on the hinge column 24, and the support member 28 is in a slightly compressed state. When the retainer 19 is installed in the through slot 26, since the outer diameter of the support member 28 is greater than the width of the through slot 26, the lower end of the support member 28 is placed on the upper end surface of the conveyor belt 7, and the support member 28 is kept compressed. Then, rotate the retaining member 19 to an angle of 90°, and then place the hinge column 24 in the hinge arc groove 27 for limiting the position. Under the elastic force of the support member 28, the retaining member 19 can be subjected to force, thereby limiting the hinge column 24 in the hinge arc groove 27, and forming a gap between the lower end surface of the retaining member 19 and the upper end surface of the conveyor belt 7, so that one end of the retaining member 19 is pressed downward.

[0050] The limit member 20 is installed on the retaining member 19. The limit member 20 is made of rubber material and is set at the end away from the pressure member 9. The pressure member 9 relies on its own elastic force to push the end of the retaining member 19 away from the pressure member 9 upward, so that the other end of the retaining member 19 applies pressure downward, and relies on its own friction to limit the handle 4.

[0051] The limiting member 20 is composed of a mounting end 29 and a contact end 30 , the angle between the mounting end 29 and the contact end 30 is less than 90°, a T-block 31 is provided on the mounting end 29 , and a T-slot 32 matching the T-block 31 is provided on the pressure section 22 .

[0052] The support member 28 and the pressure member 9 are both springs, the elastic force of the support member 28 is greater than the elastic force of the pressure member 9, and the outer diameter of the support member 28 is greater than the width of the through slot 26. After the pressure member 9 is pressed by the guide plate, the pressure member 9 is kept deformed under force, but the support member 28 is not deformed under force.

[0053] The contact end 30 is provided with a first guide slope 33, a limiting surface 34 and a second guide slope 35. The limiting surface 34 keeps in contact with the handle 4 to limit the handle 4 on the conveyor belt 7. The first guide slope 33 is convenient for guiding the placement of the handle 4, the second guide slope 35 is used to guide the removal of the handle 4, and the limiting surface 34 is used to contact with the handle 4 to generate friction and limit the position of the handle 4.

[0054] The conveyor belt 7 is also provided with a raised portion 36 for supporting the handle 4 . A through hole 37 is provided in the middle of the raised portion 36 for limiting the handle 4 .

[0055] The handle 4 is composed of a handle 38, a mounting seat 39 and a rotating rod 40. During polishing, the handle 38 and the mounting seat 39 can be polished. The rotating rod 40 is installed in cooperation with the through hole 37. The limiting surface 34 is in contact with the mounting seat 39 to increase friction and limit the position of the handle 4 on the conveyor belt 7.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
