Detailed implementation manners

[0030] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present utility model.

[0031] As Figures 2 - 9As shown in the figure, the present utility model provides an automatic polishing device for a soup spoon handle. The soup spoon handle includes a handle rod and a spoon head connecting piece. The cross-section of the handle rod and the spoon head connecting piece gradually increases from the front end to the back end. The outer edge of the connecting end surface of the spoon head connecting piece and the handle rod has a first weld seam 101, and the first weld seam 101 is elliptical. The handle rod has a second weld seam 102 along its length direction, and the second weld seam 102 is linear. Here, the second weld seam 102 is not parallel to the central axis of the handle rod. The automatic polishing device includes a base 1, a rotating table 11, at least three rotating and fixing mechanisms 2, a first grinding mechanism 3, and a second grinding mechanism 4. The rotating table 11 is rotatably arranged on the base 1, and the rotating table 11 can be driven to rotate by setting a motor. When the rotating table 11 rotates, each rotating and fixing mechanism 2 sequentially and circularly faces the first grinding mechanism 3 and the second grinding mechanism 4 in turn;

[0032] At least three rotating and fixing mechanisms 2 are equidistantly arranged on the outer edge of the rotating table 11 in a circle. Each rotating and fixing mechanism 2 includes a motor 23 for driving the soup spoon handle to rotate and a clamping assembly for clamping and fixing the soup spoon handle;

[0033] As Figure 4 shown in the figure, the first grinding mechanism 3 is arranged facing one rotating and fixing mechanism 2, and includes a first bracket 31, a first adjusting component, a first driving component, a first grinding belt 37, and a first abutting component. The first abutting component includes a first elastic member 39 and a first top wheel 311. When the first elastic member 39 is in a compressed state, the first top wheel 311 presses the first grinding belt 37 tightly against the first weld seam 101 of the soup spoon handle. The motor 23 drives the soup spoon handle to rotate, and the first driving component drives the first grinding belt 37 to move in a cycle to polish the first weld seam 101;

[0034] The first grinding belt 37 can perform a circular closed-loop movement or an up-and-down reciprocating cyclic movement. Here, the case where the first grinding belt 37 can perform a circular closed-loop movement is taken as an example for description;

[0035] Specifically, the first adjusting component includes a first horizontal driving structure 32 arranged on the first bracket 31 and a second horizontal driving structure 33 arranged on the first horizontal driving structure 32 (here, both the first horizontal driving structure 32 and the second horizontal driving structure 33 can adopt a cylinder, a slide rail, and a slide plate structure, which are prior arts and will not be elaborated here). The driving movement directions of the first horizontal driving structure 32 and the second horizontal driving structure 33 are perpendicular to each other and parallel to the horizontal plane. Here, setting the first horizontal driving structure 32 can drive the first grinding belt 37 to move closer to or farther away from the rotating and fixing mechanism 2;

[0036] The first driving assembly includes a first motor, a first driving wheel 35 and a plurality of first driven wheels 36. A first vertical plate 34 is provided on the slide plate of the second horizontal driving structure 33. The first driving wheel 35 and the plurality of first driven wheels 36 are all rotatably arranged on the first vertical plate 34. The first grinding belt 37 is arranged around the first driving wheel 35 and the plurality of first driven wheels 36. When the first motor drives the first driving wheel 35 to rotate, the first driving wheel 35 drives the first grinding belt 37 to rotate, and the first driven wheels 36 will follow the rotation of the first grinding belt 37;

[0037] As Figure 5 shown, the second grinding mechanism 4 is arranged opposite to another rotary fixing mechanism 2, and includes a second bracket 41, a second adjusting assembly, a second driving assembly, a second grinding belt 47 and a second abutting assembly. The second abutting assembly includes a second elastic member 49 and a second top wheel 411. When the second elastic member 49 is in a compressed state, the second top wheel 411 presses the second grinding belt 47 tightly against the second weld 102 of the spoon handle. The second adjusting assembly drives the second grinding belt 47 to move along the length direction of the second weld 102 to polish the second weld 102;

[0038] The second grinding belt 47 can perform a circular closed-loop movement or an up-and-down reciprocating circular movement. Here, the case where the second grinding belt 47 can perform a circular closed-loop movement is taken as an example for description;

[0039] Specifically, the second adjusting assembly includes a third horizontal driving structure 42 provided on the second bracket 41 and a fourth horizontal driving structure 43 provided on the third horizontal driving structure 42 (here, both the third horizontal driving structure 42 and the fourth horizontal driving structure 43 can adopt a cylinder, a slide rail and a slide plate structure, which are prior arts and will not be elaborated here). The driving movement directions of the third horizontal driving structure 42 and the fourth horizontal driving structure 43 are perpendicular to each other and parallel to the horizontal plane. Here, the fourth horizontal driving structure 43 is provided to drive the second grinding belt 47 to move closer to or away from the rotary fixing mechanism 2 opposite to it;

[0040] The second driving assembly includes a second motor, a second driving wheel 45 and a plurality of second driven wheels 46. A second vertical plate 44 is provided on the slide plate of the fourth horizontal driving structure 43. The second driving wheel 45 and the plurality of second driven wheels 46 are all rotatably arranged on the second vertical plate 44. The second grinding belt 47 is arranged around the second driving wheel 45 and the plurality of second driven wheels 46. When the second motor drives the second driving wheel 45 to rotate, the second driving wheel 45 drives the second grinding belt 47 to rotate, and the second driven wheels 46 will follow the rotation of the second grinding belt 47;

[0041] During use, place the handle of the spoon to be polished on the rotating and fixing mechanism 2 that is not directly facing the first polishing mechanism 3 and the second polishing mechanism 4 for fixing. Then, adjust the rotating table 11 to rotate by a certain angle so that the handle of the spoon to be polished moves to face the first polishing mechanism 3 or the second polishing mechanism 4. Here, take the handle of the spoon to be polished moving to face the first polishing mechanism 3 to polish and grind the first weld seam 101 as an example for explanation:

[0042] First, drive the first driving component to drive the first polishing belt 37 to move in a cycle, and at the same time, drive the second driving component to drive the second polishing belt 47 to move in a cycle. Adjust the first adjusting component to make the first polishing belt 37 face and fit the first weld seam 101. At this time, the first elastic member 39 is in a compressed state, and the rebounding force generated by the first elastic member 39 acts on the first top wheel 311. The first top wheel 311 presses the first polishing belt 37 tightly against the first weld seam 101 of the spoon handle, making the polishing and grinding effect better when the first polishing belt 37 rotates in a cycle for grinding work. After the first top wheel 311 presses the first polishing belt 37 tightly against the first weld seam 101 of the spoon handle, at the same time, drive the spoon handle to rotate by starting the motor 23, so as to complete the comprehensive polishing and grinding of the elliptical first weld seam 101 (it should be noted that since the first weld seam 101 is elliptical, when the spoon handle rotates, the first elastic member 39 will continuously contract or elongate, but the first elastic member 39 is always in a compressed state, ensuring that the first polishing belt 37 is always pressed tightly against the first weld seam 101 of the spoon handle);

[0043] After the first weld seam 101 is polished and ground, adjust the rotating table 11 to rotate so that the spoon handle with the polished first weld seam 101 moves to face the second polishing mechanism 4. Similarly, adjust the second adjusting component to make the second polishing belt 47 face and fit the second weld seam 102. At this time, the second elastic member 49 is in a compressed state, and the rebounding force generated by the second elastic member 49 acts on the second top wheel 411. The second top wheel 411 presses the second polishing belt 47 tightly against the second weld seam 102 of the spoon handle, making the polishing and grinding effect better when the second polishing belt 47 rotates in a cycle for grinding. While the second polishing belt 47 moves in a cycle, adjust the third horizontal driving structure 42 to drive the second polishing belt 47 to reciprocate along the length direction of the second weld seam 102, so as to complete the comprehensive polishing and grinding work of the second weld seam 102, that is, the automatic polishing and grinding work of the first weld seam 101 and the second weld seam 102 generated after the welding of the spoon handle is completed by this equipment;

[0044] While the second weld seam 102 of one spoon handle is being polished, the first polishing mechanism 3 faces another spoon handle to be polished and fixed on another rotating and fixing mechanism 2, and the first polishing mechanism 3 synchronously polishes and grinds the first weld seam 101 of another spoon handle to be polished.

[0045] like Figure 3 and Figure 6 As shown, there are four rotating fixing mechanisms 2, and the automatic polishing device further includes a third grinding mechanism 5, which includes a third bracket 51, a third adjustment assembly, a third driving assembly and a third grinding belt 57, and the first grinding mechanism 3, the second grinding mechanism 4 and the third grinding mechanism 5 are respectively opposite to one rotating fixing mechanism 2;

[0046] Specifically, the third adjustment assembly includes a fifth horizontal driving structure 52 arranged on the third bracket 51 and a sixth horizontal driving structure 53 arranged on the fifth horizontal driving structure 52 (the fifth horizontal driving structure 52 and the sixth horizontal driving structure 53 can both adopt cylinders, slide rails and slide plate structures, which are existing technologies and are not described here). The driving movement directions of the fifth horizontal driving structure 52 and the sixth horizontal driving structure 53 are perpendicular to each other and parallel to the horizontal plane. The sixth horizontal driving structure 53 is arranged here to drive the third grinding belt 57 to move closer to or away from the rotating fixing mechanism 2 facing it;

[0047] The third driving assembly includes a third motor, a third driving wheel 55 and a plurality of third driven wheels 56. A third vertical plate 54 is provided on the slide plate of the sixth horizontal driving structure 53. The third driving wheel 55 and the plurality of third driven wheels 56 are both rotatably arranged on the third vertical plate 54. A third grinding belt 57 is arranged on the periphery of the third driving wheel 55 and the plurality of third driven wheels 56. When the third motor drives the third driving wheel 55 to rotate, the third driving wheel 55 drives the third grinding belt 57 to rotate, and the third driven wheel 56 will rotate along with the third grinding belt 57. Driving the third driving assembly can drive the third grinding belt 57 to circulate.

[0048] By setting up the third grinding mechanism 5, the rotating fixing mechanism 2 on which the soup spoon handle with the first weld 101 and the second weld 102 polished is fixed is adjusted to face the third grinding mechanism 5 when the rotating table 11 is rotated, and the third adjusting component is adjusted to drive the third grinding belt 57 to move to contact the soup spoon handle. At the same time, the motor 23 of the rotating fixing mechanism 2 is started, and the fifth horizontal driving structure 52 is adjusted to drive the third grinding belt 57 to reciprocate along the length direction of the soup spoon handle, thereby completing the comprehensive polishing and grinding of the texture on the outer surface of the soup spoon handle after the first weld 101 and the second weld 102 are polished. Since the weld is not polished, no abutment component is set here, and polishing is only required by the third grinding belt 57 contacting with the outer surface of the soup spoon handle without tightening.

[0049] It should be noted that the first grinding mechanism 3 includes a first tensioning assembly 312, the second grinding mechanism 4 includes a second tensioning assembly 412, and the third grinding mechanism 5 includes a third tensioning assembly 58, which respectively adjust the tightness of the first grinding belt 37, the second grinding belt 47 and the third grinding belt 57. The specific working principles of the first tensioning assembly 312, the second tensioning assembly 412 and the third tensioning assembly 58 are existing technologies and will not be elaborated here.

[0050] like Figure 2 , Figure 3 and Figure 7 As shown, the rotating and fixing mechanism 2 includes a side plate 21 fixed on the rotating table 11, and an electric slide rail and a fixed plate 25 are arranged on the side of the side plate 21 facing away from the rotating table 11. A sliding plate 22 is slidably arranged on the electric slide rail, and a motor 23 is fixedly installed on the sliding plate 22. The output end of the motor 23 is fixedly connected to the top plate, and a plug rod 24 is fixedly installed on the side of the top plate facing the fixed plate 25. A rotating block 26 is rotatably arranged on one end of the fixed plate 25 facing the plug rod 24. The plug rod 24 can be set to be a copy of the inside of the handle rod, and because the shape is not circular, it can ensure that the handle of the soup spoon is fixed stably, and ensure that the handle of the soup spoon will not rotate during the subsequent polishing and grinding process;

[0051] The spoon handle to be polished is placed between the insertion rod 24 and the rotating block 26 by a manipulator, and the electric slide rail is adjusted to drive the sliding plate 22 to move close to the fixed plate 25, thereby driving the motor 23, the top plate and the insertion rod 24 to move close to the fixed plate 25, until the insertion rod 24 is inserted into the handle rod, and the two ends of the spoon handle are respectively in contact with the rotating block 26 and the top plate, thereby completing the fixing of the spoon handle. At the same time, when the motor 23 is started, the motor 23 drives the top plate and the insertion rod 24 to rotate, thereby driving the spoon handle and the rotating block 26 to rotate, which is convenient for the subsequent polishing and grinding of the first weld 101 and the texture on the outer surface of the spoon handle.

[0052] like Figure 1 , Figure 3 and Figure 7 As shown, it also includes a support mechanism 6. When the rotating table 11 rotates, the support mechanism 6 is sequentially located below each rotating and fixing mechanism 2. The support mechanism 6 includes a driving cylinder 61 and a support member 62 for supporting the handle of the soup spoon. The support member 62 is a U-shaped plate. Positioning notches are provided at the two top ends of the U-shaped plate, so that the robot grasps and places the handle of the soup spoon at a certain angle after the positioning notch, and will not shake at will, thereby ensuring the precise insertion of the subsequent insertion rod 24, thereby ensuring the rapid clamping and fixing of the handle of the soup spoon by the rotating and fixing mechanism 2. The output end of the driving cylinder 61 is fixedly connected to the support member 62;

[0053] By setting up the support mechanism 6, precise feeding work can be carried out, and it can play a role in transfer. Only one manipulator is required to complete the synchronous work of loading and unloading. Specifically, after the manipulator grabs the handle of the spoon to be polished and places it on the support member 62, the manipulator immediately grabs the handle of the spoon that has been polished and ground on the rotary fixing mechanism 2, and drives the sliding plate 22 to move away from the fixed plate 25 by adjusting the electric slide rail until the insertion rod 24 disengages from the handle rod, so as to facilitate the manipulator to take away and unload the polished and ground spoon handle. Subsequently, by adjusting the driving cylinder 61 to rise, the spoon handle is aligned with the insertion rod 24, thereby adjusting the rotary fixing mechanism 2 to complete the fixation of the spoon handle, that is, completing the rapid and automatic feeding work of the spoon handle to be polished.

[0054] As Figure 4 shown, the first abutting component includes a first fixing block 38. A first elastic member 39 is fixedly installed on one side of the first fixing block 38 facing the rotary table 11. One end of the first elastic member 39 is fixedly installed with a first support plate 310. A first top wheel 311 is rotatably arranged on the first support plate 310. When the first grinding belt 37 moves in a cycle, the first top wheel 311 rotates;

[0055] The first fixing block 38 is fixed on the first vertical plate 34. By setting the first top wheel 311 to be rotatably arranged on the first support plate 310, when the first top wheel 311 tightens the first grinding belt 37, the first grinding belt 37 will drive the first top wheel 311 to rotate, making the friction between the first top wheel 311 and the first grinding belt 37 a rolling friction. Compared with the fixed first top wheel 311, the wear of the first grinding belt 37 can be reduced, thereby extending its service life.

[0056] As Figure 5 shown, the second abutting component includes a second fixing block 48. A second elastic member 49 is fixedly installed on one side of the second fixing block 48 facing the rotary table 11. One end of the second elastic member 49 is fixedly installed with a second support plate 410. A second top wheel 411 is rotatably arranged on the second support plate 410. When the second grinding belt 47 moves in a cycle, the second top wheel 411 rotates;

[0057] Similarly, the second fixing block 48 is fixed on the second vertical plate 44. By setting the second top wheel 411 to be rotatably arranged on the second support plate 410, when the second top wheel 411 tightens the second grinding belt 47, the second grinding belt 47 will drive the second top wheel 411 to rotate, making the friction between the second top wheel 411 and the second grinding belt 47 a rolling friction. Compared with the fixed second top wheel 411, the wear of the second grinding belt 47 can be reduced, thereby extending its service life.

[0058] As Figure 6As shown, a collecting box 7 is provided directly below the first polishing belt 37, the second polishing belt 47, and the third polishing belt 57, facilitating the collection of waste chips from polishing and grinding. Only the collecting box 7 below the third polishing belt 57 is shown here. To avoid affecting the structural display of the first grinding mechanism 3 and the second grinding mechanism 4, Figure 4 the collecting box 7 below the first polishing belt 37 in Figure 5 and the collecting box 7 below the second polishing belt 47 in

[0059] As Figure 1 shown, further, the automatic polishing device further includes a sealing box 8. The sealing box 8 encloses the rotating table 11, the rotating fixing mechanism 2, the first grinding mechanism 3, the second grinding mechanism 4, the third grinding mechanism 5, and the supporting mechanism 6. Through the sealing box 8, the noise during polishing and grinding work can be reduced, and the waste chips generated by polishing and grinding can be prevented from spreading in the air over a large area. An inlet and outlet 81 is provided on one side of the sealing box 8, and the inlet and outlet 81 is arranged opposite to the supporting mechanism 6. Through the inlet and outlet 81, it is convenient to load the spoon handle to be polished by a manipulator and automatically unload the polished spoon handle.

[0060] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
