[0009] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained in conjunction with specific embodiments below. However, the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without making any creative work all belong to the protection scope of the present invention.

[0010] like Figure 1 , Fig.16 , Fig.17 and Fig.18 As shown, the present invention provides a kitchen utensil handle welding and polishing device, the kitchen utensil handle comprises a handle body, a kitchen utensil head connector and a hollow tube, the two ends of the hollow tube are opened and bent outward to expand the hole, the handle body has a large opening end and a small opening end, the outer wall of the handle body has a fitting edge along its length direction, the cross-sectional size of the handle body gradually decreases from the large opening end to the small opening end, and the kitchen utensil head connector forms a fitting circle when fitting with the small opening end of the handle body, and the welding and polishing device comprises a welding structure 1, a material taking and placing structure 2 and a polishing structure 3; like Figure 2 As shown, the welding structure 1 includes a first vibrating material tray 12, a second vibrating material tray 13, a third vibrating material tray 14, a first fixing mechanism 16, a first material picking mechanism 15, a second clamping assembly 17, a second material picking mechanism 18, a flipping mechanism 19, a third material picking mechanism 110, a moving table 111, a welding assembly 11 and a material unloading mechanism 114. The welding assembly 11 here includes a six-axis manipulator and a welding gun. The output end of the six-axis manipulator is fixedly connected to the welding gun. The welding assembly 11 is used to weld the fitting ring to form a first weld 101 and weld the fitting edge to form a second weld 102. The first weld 101 is elliptical. The first vibrating tray 12 is used to place the handle body, and a first discharge plate 121 is provided at the discharge end thereof; The second vibrating material tray 13 is used to place the kitchen utensil head connector, and a second discharge plate 131 is provided at the discharge end thereof; The third vibrating tray 14 is used to place the hollow tube, and a third discharge plate 141 is provided at the discharge end thereof; like Figure 3 As shown, the first fixing mechanism 16 includes a first adjusting unit 161 and a first clamping assembly 162. The output end of the first adjusting unit 161 is fixedly connected to the first clamping assembly 162. The first adjusting unit 161 here can be set as a three-axis manipulator, and the first clamping assembly 162 can be set as a pneumatic clamp. Both are existing structures and will not be described in detail here. The first material taking mechanism 15 is used to transfer the handles on the first material discharging plate 121 to the first clamping assembly 162 one by one; After the first material taking mechanism 15 transfers the handle body to the first clamping assembly 162 and is clamped and fixed by the first clamping assembly 162, the first adjusting unit 161 drives the first clamping assembly 162 to move so that the small opening end of the handle body is aligned with the kitchen utensil head connector fixed on the second clamping assembly 17, so as to facilitate subsequent welding after the two are spliced ​​together; Specifically, Figure 3 As shown, the first material taking mechanism 15 includes a first driving member 151 and a first inserting rod 152. The cross-sectional size of the first inserting rod 152 is larger than the opening size of the small opening end of the handle body and smaller than the opening size of the large opening end of the handle body. The first driving member 151 drives the first inserting rod 152 to move toward the large opening end of the handle body into the handle body and drives the handle body to move to the first clamping assembly 162. Here, the first driving member 151 is set as a cylinder. By adjusting the first driving member 151, it drives the first insertion rod 152 to move, so that it extends into a handle body facing it on the first discharge plate 121. Since the cross-sectional size of the first insertion rod 152 is larger than the opening size of the small opening end of the handle body and smaller than the opening size of the large opening end of the handle body, the first insertion rod 152 will abut against the inner wall of the handle body when it moves, so as to remove the handle body from the first discharge plate 121 and transfer it to the first clamping assembly 162. After the handle body is clamped and fixed by the first clamping assembly 162, the first driving member 151 is adjusted to reset it, and then the first vibrating material tray 12 is vibrated to discharge the material, so that the next handle body faces the first insertion rod 152, thereby completing the uninterrupted and continuous material removal work of the handle body; The second clamping assembly 17 is used to clamp and fix the kitchen utensil head connector. The second clamping assembly 17 here can also be configured as a pneumatic clamp.

[0011] like Figure 2 , Figure 4 and Figure 6 As shown, the second material taking mechanism 18 is used to transfer the kitchen utensil head connectors on the second discharging plate 131 to the second clamping assembly 17 one by one; The second material picking mechanism 18 here includes a second adjusting unit 181 and a first vacuum suction cup 182 (which is an existing device). The second adjusting unit 181 here can also be set as a three-axis manipulator. By adjusting the second adjusting unit 181, the first vacuum suction cup 182 is driven to move to adsorb the front end kitchen utensil head connector on the second discharge plate 131 of the second vibration material tray 13 and then transfer it to the second clamping assembly 17 to fix it, thereby completing the automatic material picking work of the kitchen utensil head connector one by one.

[0012] like Figure 6 As shown, the flip mechanism 19 is used to drive the handle body and the kitchen utensil head connecting piece to rotate, and the flip mechanism 19 includes a first motor 191 and a fixing piece 192 fixed to the output end of the first motor 191; After a portion of the kitchen utensil head connector is welded to the handle body, the first motor 191 is driven to drive the fixing member 192 to rotate, thereby driving the handle body, the kitchen utensil head connector and the second clamping assembly 17 to rotate synchronously. At this time, the welding assembly 11 can complete the circumferential welding of the handle body and the kitchen utensil head connector.

[0013] like Figure 2 and Figure 5 As shown, the third material taking mechanism 110 is used to take out the hollow tubes on the third material discharging plate 141 one by one; Specifically, the third material picking mechanism 110 includes a third adjusting unit 1101 and a second vacuum suction cup 1102. The third adjusting unit 1101 here can also be set as a three-axis manipulator. The second vacuum suction cup 1102 is driven to move by the third adjusting unit 1101. After the second vacuum suction cup 1102 adsorbs and fixes the hollow tube at the front end of the third discharge plate 141 at the discharge end of the third vibration material tray 14, the material picking work of the hollow tubes is completed one by one.

[0014] like Figure 6 As shown, the flipping mechanism 19 and the second clamping assembly 17 are both slidably arranged on the moving platform 111. When the flipping mechanism 19 moves along the moving platform 111 close to the second clamping assembly 17, the fixing member 192 guides the hollow tube into the large opening of the handle body and clamps it. When the second clamping assembly 17 moves along the moving platform 111 close to the first clamping assembly 162, the kitchen utensil head connector fits with the small opening end of the handle body.

[0015] like Figure 6 As shown, the blanking mechanism 114 is located on one side of the moving platform 111 and is used for blanking the welded handle.

[0016] like Fig.10 As shown, the polishing structure 3 includes a rotating table 31, at least three rotating fixing mechanisms 32, a first grinding mechanism 33 and a second grinding mechanism 34; At least three rotating and fixing mechanisms 32 are equidistantly arranged on the outer edge of the rotating platform 31, and each rotating and fixing mechanism 32 includes a third motor 323 for driving the kitchen utensil handle to rotate and a third clamping assembly for clamping and fixing the kitchen utensil handle; The rotating and fixing mechanism 32 includes a side plate 321 fixed on the rotating table 31, and an electric slide rail and a fixed plate 325 are arranged on the side of the side plate 321 facing away from the rotating table 31. A sliding plate 322 is slidably arranged on the electric slide rail, and a third motor 323 is fixedly installed on the sliding plate 322. The output end of the third motor 323 is fixedly connected to the top plate, and a third plug rod 324 is fixedly installed on the side of the top plate facing the fixed plate 325. A rotating block 326 is rotatably arranged on one end of the fixed plate 325 facing the third plug rod 324. The third plug rod 324 can be set to be a copy of the inner shape of the handle rod, and because the shape is not circular, it can ensure that the kitchen utensil handle is fixed stably, and ensure that the kitchen utensil handle will not rotate during the subsequent polishing and grinding process; The kitchen utensil handle to be polished is placed between the third insertion rod 324 and the rotating block 326 through the material taking and discharging structure 2, and the electric slide rail is adjusted to drive the sliding plate 322 to move close to the fixed plate 325, thereby driving the third motor 323, the top plate and the third insertion rod 324 to move close to the fixed plate 325 until the third insertion rod 324 is inserted into the handle rod, and the two ends of the kitchen utensil handle are respectively abutted against the rotating block 326 and the top plate, thereby completing the fixing of the kitchen utensil handle. At the same time, when the third motor 323 is started, the third motor 323 drives the top plate and the third insertion rod 324 to rotate, thereby driving the kitchen utensil handle and the rotating block 326 to rotate, which is convenient for the subsequent polishing and grinding of the first weld 101, the second weld 102 and the texture on the outer surface of the kitchen utensil handle.

[0017] like Fig.10 and Fig.12 As shown, the first grinding mechanism 33 is arranged opposite to a rotating fixing mechanism 32, and the first grinding mechanism 33 includes a first bracket 331, a first adjustment component, a first driving component and a first grinding belt 337. When the first adjustment component drives the first grinding belt 337 to move and contact the first weld 101, the third motor 323 drives the kitchen utensil handle to rotate, and the first driving component drives the first grinding belt 337 to cyclically or reciprocate to polish the first weld 101 (the first grinding belt 337 is cyclically rotated as an example for explanation in this application); The first grinding mechanism 33 also includes a first abutment assembly, which includes a first support block 338, a first elastic member 339 and a first top wheel 3311. The first support block 338 is fixed to one side of the first vertical plate 334. The first support block 338 is fixedly installed with the first elastic member 339 on the side facing the rotating table 31. One end of the first elastic member 339 is fixedly connected to the first support plate 3310. The first top wheel 3311 is rotatably arranged on the first support plate 3310. When the first grinding belt 337 circulates, the first top wheel 3311 rotates, so that there is rolling friction between the first top wheel 3311 and the first grinding belt 337. Compared with the fixed first top wheel 3311, the wear of the first grinding belt 337 can be reduced, thereby extending its service life. When the first top wheel 3311 presses the first grinding belt 337 tightly against the first weld 101 of the kitchen utensil handle, the first elastic member 339 is in a compressed state. The first adjustment component includes a first horizontal driving structure 332 arranged on the first bracket 331 and a second horizontal driving structure 333 arranged on the first horizontal driving structure 332 (the first horizontal driving structure 332 and the second horizontal driving structure 333 can both adopt cylinder, slide rail and slide plate structures, which are prior art and are not described here). The driving movement directions of the first horizontal driving structure 332 and the second horizontal driving structure 333 are perpendicular to each other and parallel to the horizontal plane. The first horizontal driving structure 332 is arranged here to drive the first grinding belt 337 to move closer to or away from the rotating fixing mechanism 32; The first driving assembly includes a first motor, a first driving wheel 335 and a plurality of first driven wheels 336. A first vertical plate 334 is provided on the slide plate of the second horizontal driving structure 333. The first driving wheel 335 and the plurality of first driven wheels 336 are both rotatably disposed on the first vertical plate 334. The first grinding belt 337 is disposed on the periphery of the first driving wheel 335 and the plurality of first driven wheels 336. When the first motor drives the first driving wheel 335 to rotate, the first driving wheel 335 drives the first grinding belt 337 to rotate, and the first driven wheel 336 will rotate following the first grinding belt 337.

[0018] like Fig.10 and Fig.13 As shown, the second grinding mechanism 34 is arranged opposite to the second rotating fixing mechanism 32, and the second grinding mechanism 34 includes a second bracket 341, a second adjusting assembly, a second driving assembly and a second grinding belt 347. When the second driving assembly drives the second grinding belt 347 to circulate or reciprocate, the second adjusting assembly drives the second grinding belt 347 to move along the length direction of the second weld 102 to polish the second weld 102 (the second grinding belt 347 is circulated and rotated as an example for explanation in this application); The second grinding mechanism 34 also includes a second abutment assembly, which includes a second support block 348, a second elastic member 349 and a second top wheel 3411. The second support block 348 is fixed to one side of the second vertical plate 344. The second support block 348 is fixedly installed with a second elastic member 349 on the side facing the rotating table 31. One end of the second elastic member 349 is fixedly installed with a second support plate 3410. The second top wheel 3411 is rotatably arranged on the second support plate 3410. When the second grinding belt 347 circulates, the second top wheel 34 11 rotates, when the second top wheel 3411 presses the second grinding belt 347 tightly against the second weld 102 of the kitchen utensil handle, the second elastic member 349 is in a compressed state, and when the second top wheel 3411 presses the second grinding belt 347 tightly, the second grinding belt 347 drives the second top wheel 3411 to rotate, so that there is rolling friction between the second top wheel 3411 and the second grinding belt 347, which can reduce the wear of the second grinding belt 347 compared with the fixed second top wheel 3411, thereby extending its service life; The second adjustment assembly includes a third horizontal driving structure 342 arranged on the second bracket 341 and a fourth horizontal driving structure 343 arranged on the third horizontal driving structure 342 (the third horizontal driving structure 342 and the fourth horizontal driving structure 343 can both adopt cylinder, slide rail and slide plate structures, which are prior art and are not described in detail here). The driving movement directions of the third horizontal driving structure 342 and the fourth horizontal driving structure 343 are perpendicular to each other and parallel to the horizontal plane. The fourth horizontal driving structure 343 is arranged here to drive the second grinding belt 347 to move closer to or away from the rotating fixing mechanism 32 facing it. The second driving assembly includes a second motor, a second driving wheel 345 and a plurality of second driven wheels 346. A second vertical plate 344 is provided on the slide plate of the fourth horizontal driving structure 343. The second driving wheel 345 and the plurality of second driven wheels 346 are both rotatably arranged on the second vertical plate 344. The second grinding belt 347 is arranged on the periphery of the second driving wheel 345 and the plurality of second driven wheels 346. When the second motor drives the second driving wheel 345 to rotate, the second driving wheel 345 drives the second grinding belt 347 to rotate, and the second driven wheel 346 will rotate following the second grinding belt 347.

[0019] The material taking and placing structure 2 is arranged opposite to the third rotating fixing mechanism 32, and is used for taking and placing the kitchen utensil handles after welding and polishing. The material taking and placing structure 2 arranged here includes a six-axis manipulator and a pneumatic clamp arranged at the output end of the six-axis manipulator.

[0020] Working principle: When the handle body, the kitchen utensil head connector and the hollow tube of the kitchen utensil handle need to be automatically and continuously welded and polished, the first material taking mechanism 15 is adjusted to take out a handle body and transfer it to the first clamping assembly 162, and then the first clamping assembly 162 is adjusted to clamp and fix the handle body. At the same time, the kitchen utensil head connector is taken out by the second material taking mechanism 18 to move it to the position facing the second clamping assembly 17. Then, the first clamping assembly 162 is driven to move by adjusting the first adjusting unit 161, so that the handle body and the kitchen utensil head connecting piece on the second clamping assembly 17 are directly opposite. At this time, the kitchen utensil head connecting piece is located between the handle body and the second clamping assembly 17. The second clamping assembly 17 is driven by a driving cylinder of the moving platform 111 to move close to the kitchen utensil head connecting piece on the slide rail. The second clamping assembly 17 takes out and fixes the kitchen utensil head connecting piece on the first vacuum suction cup 182 and then continues to move until the kitchen utensil head connecting piece and the handle body are well fitted and spliced. At this time, the six-axis manipulator is adjusted to drive the welding gun to move, and the preliminary welding and fixing of the two are completed (it should be noted that after the kitchen utensil head connecting piece on the first vacuum suction cup 182 is taken away by the second clamping assembly 17, the first vacuum suction cup 182 is adjusted to reset by the second adjusting unit 181 to take the material of the next kitchen utensil head connecting piece, and the movement of the second clamping assembly 17 and the welding work of the welding gun will not be blocked); Afterwards, the first clamping assembly 162 is adjusted to no longer fix the handle body, and the first adjusting unit 161 drives the first clamping assembly 162 to move and reset, so as to facilitate the subsequent fixing of the next handle body. The material is taken out simultaneously while the handle body and the kitchen utensil head connecting piece are welded, so as to improve the processing efficiency. Since a part of the handle body and the kitchen utensil head connecting piece is welded, the handle body will not fall off. While taking materials from the kitchen utensil head connector and the handle body, a hollow tube is taken and transferred to the front of the fixing member 192 through the third material taking mechanism 110. After a part of the handle body and the kitchen utensil head connector are welded, another driving cylinder of the moving platform 111 is adjusted to drive the flipping mechanism 19 to move close to the second clamping assembly 17, so that the fixing member 192 takes out the hollow tube on the second vacuum suction cup 1102 and introduces it into the large opening end of the handle body and initially clamps and fixes it (because the openings at both ends of the hollow tube are bent outward to expand, and the cross-sectional size of the handle body gradually decreases from the large opening end to the small opening end, so when the hollow tube gradually enters the handle body, it will be initially clamped and fixed in the handle body). At the same time, one end of the fixing member 192 is pressed against the inner wall of the handle body to fix it (to ensure that when the first motor 191 drives the fixing member 192 to rotate, it can drive the handle body to rotate. The specific fixing method is described below); After the fixing member 192 fixes the handle body, the fixing member 192 is driven to rotate by starting the first motor 191, thereby driving the handle body, the kitchen utensil head connecting member and the second clamping assembly 17 to rotate. While the handle body and the kitchen utensil head connecting member rotate, the circumferential welding work of the joint between the two can be completed by the welding assembly 11, thereby forming the first weld 101 (because the circumferential welding work cannot be performed only by adjusting the welding assembly 11, unless the position of the second clamping assembly 17 is set very high, so that there is enough space and distance between it and the moving platform 111 to allow the six-axis manipulator of the welding assembly 11 to move, but this will increase the overall height of the equipment. Here, the second clamping assembly 17 can be set about 20 centimeters away from the moving platform 111, so as to avoid the second clamping assembly 17 from being too high, thereby avoiding the overall height of the equipment from being too high, making it convenient for people to observe the automatic welding situation, and to a certain extent, it can also reduce the equipment cost. The welding work of the handle body and the kitchen utensil head connecting member can also be completed through preliminary welding and the second step of circumferential welding distribution welding); After the welding of the handle body and the kitchen utensil head connector is completed, the first motor 191 is adjusted to place the fitting edge of the handle body in a suitable position (such as facing upwards) to facilitate the welding work of the welding assembly 11. After the welding of the fitting edge is completed, a second weld 102 is formed on the handle body. Then, the driving cylinder of the moving platform 111 is adjusted to reset the fixing member 192 so that it does not block the subsequent welding work of the welding gun. Finally, the welding of the handle body and the hollow tube is completed by adjusting the six-axis manipulator to drive the welding gun to move. On the basis of the above, the welding structure 1 further includes a rotating mechanism 112, which is used to convert the handle body and the kitchen utensil head connecting piece from a horizontal state to an inclined or vertical state, and the rotating mechanism 112 includes a second motor 1121 and a fixed block 1122, the output end of the second motor 1121 is fixedly connected to the fixed block 1122, the second clamping assembly 17 is rotatably arranged on one side of the fixed block 1122, and the first motor 191 and the second motor 1121 are arranged perpendicular to each other and are parallel to the horizontal plane; After the hollow tube is initially clamped on the handle body, and the turning mechanism 19 is reset by adjusting the driving cylinder of the moving platform 111, the second motor 1121 is started to drive the fixing block 1122 to rotate, thereby driving the second clamping assembly 17, the handle body, the spoon head connector and the hollow tube to rotate, so that the handle body is in an inclined or vertical state, further ensuring that the six-axis manipulator has enough movement space to drive the welding gun, and avoiding the need to adjust the distance between the fixing member 192 and the handle body when the handle body is in a horizontal state, resulting in a too long stroke of the turning mechanism 19, thereby increasing the floor space of the equipment; The unloading mechanism 114 is set here as a pneumatic clamp, which is tilted or vertically arranged on one side of the moving platform 111, and when the handle body is in a tilted or vertical state and the welding of the handle body and the hollow tube is completed, the second motor 1121 is driven to rotate again, so that the handle body with the hollow tube welded can be clamped and fixed by the unloading mechanism 114. At this time, the second clamping component 17 is adjusted to no longer fix the kitchen utensil head connecting piece, thereby completing the rapid unloading of the welded handle. The unloading mechanism 114 is only a pneumatic clamp with a simple structure and low cost. After the second clamping component 17 no longer fixes the kitchen utensil head connecting piece, it is adjusted to rotate and reset through the second motor 1121, so as to facilitate the fixation of the next kitchen utensil head connecting piece, that is, to carry out the welding work of the next handle. The welding of the handle is Fig.16 Status converted to Fig.17 state; Then, the welded handle on the unloading mechanism 114 is taken out by the material taking and unloading structure 2 and transferred to the rotating fixing mechanism 32 which is not facing the first grinding mechanism 33 and the second grinding mechanism 34 for fixing. Then, the rotating table 31 is adjusted to rotate a certain angle so that the kitchen handle to be polished moves to face the first grinding mechanism 33 or the second grinding mechanism 34. Here, the kitchen handle to be polished is first moved to face the first grinding mechanism 33 to polish the first weld 101 as an example for explanation: First, the first driving assembly is driven to drive the first grinding belt 337 to circulate, and the second driving assembly is driven to drive the second grinding belt 347 to circulate. The first adjusting assembly is adjusted to make the first grinding belt 337 face and fit the first weld 101. At this time, the first elastic member 339 is in a compressed state, and the rebound force generated by the first elastic member 339 acts on the first top wheel 3311. The first top wheel 3311 pushes the first grinding belt 337 tightly against the first weld 101 of the kitchen utensil handle, so that the first grinding belt 337 has a polishing effect when it circulates and performs grinding work. The effect is better. After the first top wheel 3311 presses the first grinding belt 337 tightly against the first weld 101 of the kitchen utensil handle, the third motor 323 is started to drive the kitchen utensil handle to rotate, so that the elliptical first weld 101 can be fully polished (it should be noted that since the first weld 101 is elliptical, when the kitchen utensil handle rotates, the first elastic member 339 will continue to shrink or stretch, but the first elastic member 339 is always in a compressed state, ensuring that the first grinding belt 337 is always pressed tightly against the first weld 101 of the kitchen utensil handle); After the first weld 101 is polished and ground, the rotating table 31 is adjusted to rotate so that the kitchen handle with the polished first weld 101 moves to face the second grinding mechanism 34. Similarly, the second adjustment component is adjusted to make the second grinding belt 347 face and fit the second weld 102. At this time, the second elastic member 349 is in a compressed state, and the rebound force generated by the second elastic member 349 acts on the second top wheel 3411. The second top wheel 3411 pushes the second grinding belt 347 tightly against the second weld 102 of the kitchen handle, so that the second grinding belt 347 has a better polishing effect when it is cyclically rotated for grinding. While the second grinding belt 347 is cyclically moving, the third horizontal driving structure 342 is adjusted to drive the second grinding belt 347 to reciprocate along the length direction of the second weld 102, thereby completing the comprehensive polishing and grinding of the second weld 102, that is, the first weld 101 and the second weld 102 generated after the kitchen handle is welded are automatically polished and ground by the device. After the first weld 101 and the second weld 102 are polished, the handle Fig.17 Status converted to Fig.18 state, at this time, the rotating table 31 is adjusted to rotate so that the rotating fixing mechanism 32 with the polished handle fixed is facing the material taking and discharging structure 2, so as to facilitate the subsequent material taking and discharging structure 2 to complete the automatic unloading work of the polished handle. After unloading, the loading work of the next handle to be polished can continue; In addition, while the second weld 102 of one kitchen utensil handle is being polished, the first polishing mechanism 33 is facing another kitchen utensil handle to be polished and fixed on another rotating fixing mechanism 32, and the first polishing mechanism 33 synchronously polishes the first weld 101 of the other kitchen utensil handle to be polished and polished.

[0021] In addition, it should be noted that by setting up a movable table 111 and setting up two cylinders to respectively drive the flipping mechanism 19 and the second clamping assembly 17 to move on the slide rail, the first adjustment unit 161, the second adjustment unit 181 and the third adjustment unit 1101 can be made to perform movement adjustment on only two axes (i.e., the vertical direction and the horizontal direction perpendicular to the slide rail).

[0022] like Figure 6 and Figure 7 As shown, the welding structure 1 also includes a locking mechanism 113, which is located on one side of the fixed block 1122. The locking mechanism 113 includes a second driving member 1131, a fixed rod 1132 and a rotating rod 1133. The outer wall of the rotating rod 1133 is provided with a plug hole along a direction perpendicular to the central axis thereof. The second clamping assembly 17 is fixedly connected to the rotating rod 1133 at one end facing the fixed block 1122. The rotating rod 1133 is rotatably arranged in the fixed block 1122, and the second driving member 1131 drives the fixed rod 1132 to move in and out of the plug hole; When the second motor 1121 drives the fixed block 1122 to rotate so that the handle body is inclined or perpendicular to the top surface of the movable platform 111, the second clamping assembly 17 is prevented from shaking on the fixed block 1122. By adjusting the second driving member 1131 to drive the fixed rod 1132 to move into the socket of the rotating rod 1133, the rotating rod 1133 is fixed, that is, the second clamping assembly 17 is fixed, thereby ensuring the stability of the handle body when being welded to the hollow tube.

[0023] like Figure 8 As shown, the fixing member 192 is a second plug rod, which is in a boss shape and has a large cross-section section and a small cross-section section. The cross-sectional size of the small cross-sectional section of the second plug rod is larger than the opening size of the small opening end of the handle body and smaller than the opening size of the large opening end of the handle body. The cross-sectional size of the large cross-sectional section of the second plug rod is larger than the opening size of the large opening end of the handle body. The cross-sectional size of the small cross-sectional section of the second plug rod is not larger than the cross-sectional size inside the hollow tube. It is preferred that the cross-sectional size of the small cross-sectional section of the second plug rod is adapted to the cross-sectional size inside the hollow tube. In this way, it can be ensured that the driving cylinder of the moving platform 111 drives the flip mechanism 19 to move, thereby driving the second plug rod to transport the hollow tube, and the hollow tube will not rotate, thereby ensuring that the hollow tube is accurately introduced into the handle body. The second insertion rod here has two functions. One is to cooperate with the second clamping assembly 17 to tighten and fix the handle body to facilitate the subsequent circumferential welding of the handle body and the spoon head connecting piece. The other is to push the hollow tube into the handle body: Specifically, a boss-shaped second plug rod is provided here, so that after the small cross-section section of the second plug rod enters the handle body, the end surface where the large cross-section section of the second plug rod and the small cross-section section are connected abuts against the handle body, thereby cooperating with the second clamping assembly 17 to fix the handle body, so that the first motor 191 can drive the second plug rod to rotate and drive the handle body to rotate; In addition, when the second insertion rod needs to guide the hollow tube into the handle body for clamping, the turning mechanism 19 is driven by the driving cylinder to move close to the second clamping assembly 17, thereby driving the second insertion rod to move to remove the hollow tube on the second vacuum suction cup 1102 and guide it into the handle body. Since the cross-sectional size of the handle body gradually decreases from the large opening end to the small opening end, and the openings at both ends of the hollow tube are bent outward to expand, the outer wall of one end of the hollow tube that is bent outward to expand will be clamped in the handle body as it gradually enters the handle body, until the hollow tube completely enters the handle body, at this time the outer wall of the other end of the hollow tube that is bent outward to expand will also be clamped in the handle body (such as Fig.16 and Fig.17 As shown), the hollow tube is initially clamped and fixed in the handle body. At this time, the end face of the large cross-section section of the second insertion rod abuts against the large open end of the handle body. Subsequently, the driving cylinder of the movable table 111 drives the flipping mechanism 19 to move away from the second clamping assembly 17, so that the second insertion rod is separated from the hollow tube and the handle body, which facilitates the subsequent welding work of the hollow tube and the handle body.

[0024] Here, there are four rotating and fixing mechanisms 32, and the polishing structure 3 also includes a third grinding mechanism 35, which includes a third bracket 351, a third adjustment component, a third driving component and a third grinding belt 357. The first grinding mechanism 33, the second grinding mechanism 34 and the third grinding mechanism 35 are respectively opposite to a rotating and fixing mechanism 32 (at this time, a sealing box 5 is arranged on the periphery of the entire polishing structure 3, and a material inlet and outlet 51 is opened on one side of the sealing box 5. The material inlet and outlet 51 is arranged opposite to the supporting mechanism 36. Through the sealing box 5, the noise in the polishing and grinding work can be reduced, and the waste generated by the polishing and grinding can be reduced from being scattered in the air over a large area. Through the material inlet and outlet 51, it is convenient to load the kitchen utensil handle to be polished by the robot and automatically unload the polished kitchen utensil handle); The third adjustment assembly includes a fifth horizontal driving structure 352 disposed on the third bracket 351 and a sixth horizontal driving structure 353 disposed on the fifth horizontal driving structure 352 (the fifth horizontal driving structure 352 and the sixth horizontal driving structure 353 can both adopt cylinders, slide rails and slide plates, which are prior arts and are not described in detail here). The driving movement directions of the fifth horizontal driving structure 352 and the sixth horizontal driving structure 353 are perpendicular to each other and parallel to the horizontal plane. The sixth horizontal driving structure 353 is disposed here to drive the third grinding belt 357 to move closer to or away from the rotating fixing mechanism 32 facing it. The third driving assembly includes a third motor, a third driving wheel 355 and a plurality of third driven wheels 356. A third vertical plate 354 is provided on the slide plate of the sixth horizontal driving structure 353. The third driving wheel 355 and the plurality of third driven wheels 356 are both rotatably arranged on the third vertical plate 354. The third grinding belt 357 is arranged on the periphery of the third driving wheel 355 and the plurality of third driven wheels 356. When the third motor drives the third driving wheel 355 to rotate, the third driving wheel 355 drives the third grinding belt 357 to rotate, and the third driven wheel 356 will rotate along with the third grinding belt 357. Driving the third driving assembly can drive the third grinding belt 357 to circulate. By setting the third grinding mechanism 35, the rotating fixing mechanism 32 on which the kitchen utensil handle on which the first weld 101 and the second weld 102 have been ground is adjusted to face the third grinding mechanism 35 when the rotating table 31 is rotated, and the third adjusting component is adjusted to drive the third grinding belt 357 to move to contact the kitchen utensil handle, and at the same time, the third motor 323 of the rotating fixing mechanism 32 is started, and the fifth horizontal driving structure 352 is adjusted to drive the third grinding belt 357 to reciprocate along the length direction of the kitchen utensil handle, thereby completing comprehensive polishing and grinding of the texture on the outer surface of the kitchen utensil handle on which the first weld 101 and the second weld 102 have been ground. Since the weld is not polished, no abutting component is provided here, and polishing is only required by the third grinding belt 357 contacting and polishing the outer surface of the kitchen utensil handle without tightening.

[0025] A collection box 4 is provided directly below the first grinding belt 337, the second grinding belt 347 and the third grinding belt 357 to facilitate the collection of polishing waste chips. Only the collection box 4 below the third grinding belt 357 is shown here. To avoid affecting the structural display of the first grinding mechanism 33 and the second grinding mechanism 34, the collection box 4 below the first grinding belt 337 and the second grinding belt 347 is not drawn.

[0026] like Fig.11 and Fig.15 As shown, the polishing structure 3 also includes a supporting mechanism 36. When the rotating table 31 rotates, the supporting mechanism 36 is sequentially located below each rotating fixing mechanism 32. The supporting mechanism 36 includes a driving gas rod 361 and a supporting member 362 for supporting the handle of the kitchen utensil. The output end of the driving gas rod 361 is fixedly connected to the supporting member 362. The supporting member 362 is a U-shaped plate, and positioning notches are provided at the two top ends of the U-shaped plate. By setting up the support mechanism 36, accurate loading work can be carried out, and it can play a role of transfer. Only one manipulator and one pneumatic clamp are needed to complete the synchronous loading and unloading work. Specifically, after the manipulator grabs the kitchen utensil handle to be polished and places it on the support member 362, the manipulator drives the pneumatic clamp to immediately grab the kitchen utensil handle that has been polished on the rotating fixing mechanism 32, and drives the sliding plate 322 to move away from the fixing plate 325 by adjusting the electric slide rail until the third insertion rod 324 is separated from the handle body, thereby facilitating the manipulator to take away the polished kitchen utensil handle for unloading, and then adjust the driving gas rod 361 to rise so that the kitchen utensil handle is facing the third insertion rod 324, thereby adjusting the rotating fixing mechanism 32 to complete the fixation of the kitchen utensil handle, that is, complete the rapid and automatic loading of the kitchen utensil handle to be polished, which saves waiting time to a certain extent and avoids the use of pneumatic clamps for loading and unloading work separately.
