For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0033] As Figures 1 to 4 shown, a laser marking device 1 for a health care kettle includes a frame body 10, a laser mechanism 20 and a positioning mechanism 30. The laser mechanism 20 is used to mark the kettle body. The positioning mechanism 30 includes a bottom plate 31, a tray 32, a support frame 33, a clamping block 34 and a sensing member 35. The bottom plate 31 is arranged on the frame body 10, the tray 32 is arranged on the bottom plate 31, a material placing groove 321 for receiving the kettle body is formed on the tray 32, the support frame 33 is arranged on the bottom plate 31, the clamping block 34 is slidably arranged along the vertical direction on one side of the support frame 33 close to the material placing groove 321, and the clamping block 34 is used to clamp the spout of the kettle body when sliding downward. The sensing member 35 is arranged on the bottom plate 31, and the sensing member 35 is used to sense whether a kettle body is placed on the tray 32.

[0034] It should be noted that the tray 32 is arranged on the bottom plate 31, and the tray 32 is located in the middle of the bottom plate 31. A material placing groove 321 for receiving the kettle body is formed in the tray 32. The diameter of the material placing groove 321 is larger than the diameter of the bottom of the kettle body. When the kettle body is placed in the material placing groove 321, the bottom of the kettle body is completely embedded in the material placing groove 321, so that the kettle body is fixed on the tray 32. Further, the support frame 33 is arranged on the bottom plate 31. One side surface of the support frame 33 is attached to one side surface of the tray 32. The height of the support frame 33 is greater than the height of the kettle body. The clamping block 34 is slidably arranged on the support frame 33 along the vertical direction, so that the height of the clamping block 34 sliding upward to the highest point of the support frame 33 is greater than the height of the kettle body, and the clamping block 34 is located on the side of the support frame 33 close to the material placing groove 321. When the clamping block 34 slides downward, the clamping block 34 can clamp the spout of the kettle body from top to bottom, so as to fix the kettle body on the tray 32. When the kettle body is placed on the tray 32, since the bottom of the kettle body is embedded in the material placing groove 321 and the clamping block 34 slides downward to clamp the spout of the kettle body, in this way, the kettle body can be stably fixed on the tray 32, and by clamping the spout with the clamping block 34, the kettle body is always fixed in one direction on the tray 32.

[0035] As Figures 2 to 4 shown, in an embodiment, the support frame 33 includes a support block 331, a slider 332 and two sliding rods 333. The support block 331 is arranged on the bottom plate 31. The two sliding rods 333 are both arranged at the end of the support block 331 away from the bottom plate 31, and the other ends of the two sliding rods 333 are vertically inserted through the slider 332, so that the slider 332 can slide up and down relative to the support frame 33. The clamping block 34 is arranged on the slider 332.

[0036] It should be noted that the support block 331 is arranged on the bottom plate 31. One side surface of the support block 331 is attached to one side surface of the tray 32, so that the clamping block 34 on the support block 331 can be close to the kettle body on the material placing groove 321, facilitating the clamping block 34 to tightly clamp the kettle spout. The two sliding rods 333 are both arranged at intervals along the vertical direction at one end of the support block 331 away from the bottom plate 31, and the other ends of the two sliding rods 333 are both inserted through the two ends of the sliding block 332 along the vertical direction at intervals, enabling the sliding block 332 to slide up and down relative to the support block 331 on the sliding rods 333. It should be noted that limit pieces are installed at the other ends of the two sliding rods 333, and the limit pieces are used to prevent the sliding block 332 from sliding out of the sliding rods 333. Further, the clamping block 34 is arranged on the sliding block 332. Thus, when the sliding block 332 slides up and down relative to the support block 331, the sliding block 332 will drive the clamping block 34 to slide up and down relative to the support block 331, and further enable the clamping block 34 to slide down to tightly clamp the kettle spout or slide up to release the kettle spout. For example, when the height of the kettle body changes, the clamping block 34 can also slide up and down according to the height of the kettle body, adjusting the height between the clamping block 34 and the kettle spout to keep the clamping block 34 tightly clamping the kettle spout all the time. In one embodiment, a screw is screwed on one side of the sliding block 332. By rotating the screw to make it press against the sliding rod 333, the sliding block 332 can be firmly pressed against the kettle spout.

[0037] As Figures 3 to 4 shown, in one embodiment, two cross bars 341 are arranged on the surface of the clamping block 34 close to the sliding block 332, and the other ends of the two cross bars 341 are horizontally inserted through the sliding block 332, enabling the clamping block 34 to slide horizontally relative to the sliding block 332.

[0038] It should be noted that two cross bars 341 are arranged on the surface of the clamping block 34 close to the sliding block 332, and the two cross bars 341 are arranged at intervals on one surface of the clamping block 34. The other ends of the two cross bars 341 are both horizontally inserted through the two ends of the sliding block 332 at intervals. Since the clamping block 34 is arranged on the sliding block 332 and the clamping block 34 is located on one side of the support frame 33 close to the material placing groove 321, the clamping block 34 can slide horizontally relative to the sliding block 332 and can slide close to or away from the kettle spout. It should be noted that limit pieces are also installed at the other ends of the two cross bars 341, and the limit pieces are used to prevent the clamping block 34 from sliding out of the sliding block 332. For example, when the kettle mouth of the kettle body changes, the position of the kettle spout on the edge of the kettle mouth will also change accordingly, and the clamping block 34 can also slide horizontally according to the position of the kettle spout, adjusting the position between the clamping block 34 and the kettle spout to keep the clamping block 34 tightly clamping the kettle spout all the time.

[0039] As Figures 1 to 4 shown, in one embodiment, a right-angle groove 342 is formed on the clamping block 34, and the right-angle groove 342 is used for clamping connection with the kettle body.

[0040] It should be noted that a right-angle groove 342 is formed at one end of the clamping block 34 facing the material placing groove 321. The right-angle groove 342 is used for clamping with the spout on the kettle body. The width of the opening of the right-angle groove 342 is greater than the width of the spout. In this way, when the right-angle groove 342 is clamped on the spout, the two inner side walls of the right-angle groove 342 are simultaneously abutted against the two side edges of the spout. Moreover, since the clamping block 34 clamps the spout from top to bottom, under the action of gravity, the two inner side walls of the right-angle groove 342 always remain in contact with the two side edges of the spout. In this way, the clamping block 34 can keep clamping the spout so that the kettle body is fixed on the tray 32. Further, since the clamping block 34 can slide up and down relative to the support frame 33, the position where the clamping block 34 clamps the spout is always on a vertical line. When the clamping block 34 clamps the spout, each kettle body faces in one direction to unify the product marking position. Further, the two sides of the right-angle groove 342 respectively extend from one end of the clamping block 34 facing the material placing groove 321 into the clamping block 34, so that the opening of the right-angle groove 342 becomes larger from inside to outside. When facing spouts of different sizes, the two inner side walls of the right-angle groove 342 can clamp the two side edges of the spout. In this way, when replacing kettle bodies of different models, the clamping block 34 can also clamp the spout on the kettle body and fix it on the tray 32.

[0041] As Figure 4 shown, in an embodiment, a sponge 3421 is provided on the inner side wall of the right-angle groove 342.

[0042] It should be noted that the right-angle groove 342 is used for clamping the spout to fix the spout on the tray 32. Since the right-angle groove 342 is formed at one end of the clamping block 34 facing the material placing groove 321 and the clamping block 34 can slide up and down relative to the support frame 33, under the action of gravity, when the clamping block 34 slides down from top to clamp the spout, it is easy for the clamping block 34 to damage the spout. A sponge 3421 is provided on the two inner side walls of the right-angle groove 342 in contact with the spout to prevent the clamping block 34 from damaging the spout.

[0043] As Figure 3 、 Figure 6 shown, in an embodiment, the material placing groove 321 includes a U-shaped part 3211 and an O-shaped part 3212. One end of the U-shaped part 3211 is communicated with the O-shaped part 3212, and the O-shaped part 3212 is located below the U-shaped part 3211. The other end of the U-shaped part 3211 extends to one side surface of the tray 32.

[0044] It should be noted that one end of the U-shaped part 3211 has a circular structure. The diameter of the circular structure of the U-shaped part 3211 is larger than that of the O-shaped part 3212, and the O-shaped part 3212 is located below one end of the U-shaped part 3211. Since the O-shaped part 3212 is connected to one end of the U-shaped part 3211, a circular stepped structure is formed between the O-shaped part 3212 and one end of the U-shaped part 3211. Further, the other end of the U-shaped part 3211 extends to a side surface of the tray 32, forming a slideway on the tray 32. The kettle body can slide through the slideway on the tray 32 to the circular stepped structure formed by the O-shaped part 3212 and one end of the U-shaped part 3211. Further, both sides of the slideway are tangent to the O-shaped part 3212. When the kettle body slides in from the slideway, the circular opening at the bottom of the kettle body first slides along the slideway. When it slides to the O-shaped part 3212, the circular opening at the bottom of the kettle body is embedded in the O-shaped part 3212, and at the same time, the bottom of the kettle body is also embedded in the U-shaped part 3211 to fix the kettle body on the material placing groove 321. In this way, the kettle body slides into the material placing groove 321 in a sliding manner, enabling the kettle body to be quickly placed in the material placing groove 321 to improve production efficiency.

[0045] As Figure 1 , Figure 3 , Figure 5 shown, in one embodiment, the sensing member 35 includes a transmitter 351 and a receiver 352. The transmitter 351 and the receiver 352 are respectively arranged at both ends of the bottom plate 31, and the transmitter 351 and the receiver 352 are respectively located on both sides of the material placing groove 321. The transmitter 351 and the receiver 352 are used to detect whether a kettle body is placed on the tray 32.

[0046] It should be noted that both the transmitter 351 and the receiver 352 are connected to the control device. For example, the control device is a PLC. Since the transmitter 351 and the receiver 352 are respectively located on both sides of the material placing groove 321, the light emitted by the transmitter 351 will pass through the material placing groove 321 and enter the receiver 352. When a kettle body is placed on the material placing groove 321, the kettle body blocks the light emitted by the transmitter 351, making the light unable to enter the receiver 352. When the receiver 352 receives the light emitted by the transmitter 351, it can be judged that there is no kettle body placed on the material placing groove 321. When the receiver 352 does not receive the light emitted by the transmitter 351, it can be judged that there is a kettle body placed on the material placing groove 321. In this way, the control device can control the laser mechanism 20 to work according to the reception information on the receiver 352.

[0047] As Figure 5 shown, in one embodiment, the sensing member 35 further includes two upright frames 353. The two upright frames 353 are respectively arranged at both ends of the bottom plate 31, and the transmitter 351 and the receiver 352 are respectively arranged on the two upright frames 353.

[0048] It should be noted that the sensing member 35 further includes a plurality of supporting pieces 354. The upright frame 353 and each supporting piece 354 are both of L-shaped structures. One side of the upright frame 353 is disposed on the bottom plate 31, and a waist-shaped hole is formed on one side of the upright frame 353. The upright frame 353 is screwed to the bottom plate 31 through the waist-shaped hole by a screw. When the screw is tightened, the upright frame 353 is fixed on the bottom plate 31. When the screw is loosened, the upright frame 353 can slide on the bottom plate 31. Further, a waist-shaped hole is also formed along the vertical direction on the other side of the upright frame 353. One side of each supporting piece 354 is screwed to the other side of the upright frame 353 through the waist-shaped hole by a screw. When the screw is tightened, the supporting piece 354 is fixed on the other side of the upright frame 353. When the screw is loosened, the supporting piece 354 can slide up and down on the other side of the upright frame 353. Each transmitter 351 is screwed to the supporting piece 354 on one of the upright frames 353 at both ends of the bottom plate 31 by a screw, and each receiver 352 is screwed to the supporting piece 354 on the other upright frame 353 at both ends of the bottom plate 31 by a screw. Moreover, the number and height of each transmitter 351 and each receiver 352 at both ends of the bottom plate 31 are the same, so that each transmitter 351 and each receiver 352 form a light fence relative to the placing groove 321. When a kettle body is placed on the placing groove 321, the kettle body will block the formation of the light fence. In this way, the sensing member 35 can detect whether a kettle body is placed on the tray 32.

[0049] As Figure 1 shown, in one embodiment, the laser mechanism 20 includes a lifting module 21 and a laser 22. The lifting module 21 is disposed on the frame body 10, and the laser 22 is disposed on the output shaft of the lifting module 21, and the laser 22 is oriented towards the placing groove 321.

[0050] It should be noted that the lifting module 21 is vertically disposed on the frame body 10 and is screwed to the frame body 10 by a screw. The laser 22 is slidably disposed on the output shaft of the lifting module 21, so that the laser 22 can slide relative to the lifting module 21. The laser 22 is oriented towards the placing groove 321, so that the focal point of the laser 22 can be focused on the kettle body. Further, since the laser 22 can slide relative to the lifting module 21, the laser 22 can slide and adjust the position of the focal point according to the height of the kettle body to meet various marking requirements. In one embodiment, the lifting module 21 is a slide rail module driven by a screw. The laser 22 is a device for generating laser in the prior art.

[0051] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
