The feeding and conveying assembly 200 is installed on the base 100. The feeding and conveying assembly 200 includes a feeding-in place station G11, and the feeding and conveying assembly 200 is used to convey the battery product 2000 to the feeding-in place station G11.

[0024] Figure 5 It is a three-dimensional schematic diagram of the turntable assembly in an embodiment of the laser marking machine of the present invention. The turntable assembly 300 is installed on the base 100. The turntable assembly 300 includes a rotation driving assembly 310 and four carrier plate assemblies 320. The four carrier plate assemblies 320 are installed on the rotation driving assembly 310. The rotation driving assembly 310 is used to drive each carrier plate assembly 320 to cycle and sequentially move to the loading station G21, the processing station G22, the unloading station G23, and the preparation station G24, where the loading station G21 and the feeding-in place station G11 are arranged side by side along the first direction X. In this embodiment, the rotation driving assembly 310 drives the carrier plate assembly 320 to rotate 90 degrees each time, and the carrier plate assembly 320 changes its station once. During the rotation process, the carrier plate assembly 320 sequentially switches to the loading station G21, the processing station G22, the unloading station G23, the preparation station G24, and then switches to the loading station G21 again for cycling.

[0025] Figure 6This is a three-dimensional schematic diagram of the vision and laser marking components in an embodiment of the laser marking machine of the present invention. The vision and laser marking components 400 are installed on the base 100. The vision and laser marking components 400 include a first camera 410, a second camera 420, and a laser marking head 430. The first camera 410 and the second camera 420 are arranged side by side along the first direction X. Among them, the first camera 410 is located above the feeding-in place station G11. The second camera 420 is located above the loading station G21. The laser marking head 430 is located above the processing station G22. The first camera 410 is used to collect images of the battery product 2000 located at the feeding-in place station G11 and judge the front and back sides. The second camera 420 is used to perform position positioning and angle positioning on the battery product 2000 located at the loading station G21 to obtain positioning information. The laser marking head 430 is used to perform laser marking on the battery product 2000 located at the processing station G22 based on the positioning information. The unqualified material conveying component 500 is installed on the base 100. The loading manipulator 600 is installed on the base 100. The loading manipulator 600 is set to, when the first camera 410 determines that the battery product 2000 is in the front state, transport the battery product 2000 from the feeding-in place station G11 to the carrier plate component 320 at the loading station G21, and when the first camera 410 determines that the battery product 2000 is in the back state, transport the battery product 2000 from the feeding-in place station G11 to the unqualified material conveying component 500.

[0026] The laser marking machine 1000 according to an embodiment of the present invention includes a base 100, and a feeding and conveying assembly 200, a turntable assembly 300, a vision and laser marking assembly 400, a defective product conveying assembly 500, and a loading manipulator 600 mounted on the base 100. The turntable assembly 300 includes a rotation driving assembly 310 and four carrier plate assemblies 320. The rotation driving assembly 310 is used to drive each carrier plate assembly 320 to cycle and sequentially move to the loading station G21, the processing station G22, the unloading station G23, and the preparation station G24. Since the turntable assembly 300 includes four carrier plate assemblies 320, therefore, when the rotation driving assembly 310 completes the rotation switching each time, there is one carrier plate assembly 320 at each of the loading station G21, the processing station G22, the unloading station G23, and the preparation station G24. Therefore, when laser marking the battery product 2000 at the processing station G22, the unloading operation of the previous battery product 2000 that has completed laser marking can be implemented at the unloading station G23 at the same time, and the loading operation of the next battery product 2000 to be laser marked can be implemented at the loading station G21 at the same time, and a free carrier plate assembly 320 has been provided at the preparation station G24 at the same time, which is convenient for carrying the battery product 2000 to be laser marked after switching to the loading station G21. Therefore, the loading, laser marking, and unloading of the battery product 2000 can be carried out collaboratively, and there is no need to wait for a long time at a specific station, improving the beat of the laser marking process of the battery product 2000, thereby facilitating the improvement of the production efficiency of the battery product 2000. In the laser marking machine 1000 according to an embodiment of the present invention, the feeding and conveying assembly 200 includes a feeding in-place station G11, and the vision and laser marking assembly 400 includes a first camera 410 and a second camera 420. The loading manipulator 600 is configured to move the battery product 2000 from the feeding in-place station G11 to the carrier plate assembly 320 at the loading station G21 when the first camera 410 determines that the battery product 2000 is in the front state, and move the battery product 2000 from the feeding in-place station G11 to the defective product conveying assembly 500 when the first camera 410 determines that the battery product 2000 is in the reverse state. By collecting the image of the battery product 2000 located at the feeding in-place station G11 by the first camera 410 and judging the front and back sides, it is possible to prevent the battery product 2000 in the reverse state from entering the processing station G22, ensuring the reliability of the laser marking operation. The loading station G21 and the feeding in-place station G11 are arranged side by side along the first direction X, and the first camera 410 and the second camera 420 are arranged side by side along the first direction X, making the structural layout of the feeding and conveying assembly 200, the turntable assembly 300, and the vision and laser marking assembly 400 in the laser marking machine 1000 more compact, thereby reducing the waste of space in the laser marking machine 1000, making the distance between multiple stations closer, and facilitating the further improvement of the beat of the laser marking process of the battery product 2000.

[0027] For example Figure 5 Figure 5 , in some embodiments, each carrier plate assembly 320 includes a carrier table 321, a first magnetic attraction member 322, and a first lifting drive member 323. The carrier table 321 includes a bearing surface for bearing the battery product 2000. The first magnetic attraction member 322 is located below the bearing surface, and the first magnetic attraction member 322 can magnetically adsorb the battery product 2000.

[0028] The first lifting drive member 323 is connected to the first magnetic attraction member 322. The first lifting drive member 323 is used to drive the first magnetic attraction member 322 to move up and down. Wherein, the first magnetic attraction member 322 adsorbs and limits the battery product 2000 on the bearing surface in the raised state, and the first magnetic attraction member 322 releases the limit on the battery product 2000 on the bearing surface in the lowered state. Figure 5 Figure 5 , in order to clearly show a part of the structure of the carrier plate assembly 320, the first lifting drive members 323 of the two carrier plate assemblies 320 are hidden and shown.

[0029] In this embodiment, when the carrier table 321 located at the loading station G21 receives the battery product 2000, the first lifting drive member 323 drives the first magnetic attraction member 322 to rise, so as to adsorb and limit the battery product 2000. When the carrier plate assembly 320 moves to the processing station G22, the first magnetic attraction member 322 remains in the raised state, so as to continuously limit the battery product 2000, avoiding the relative sliding of the battery product 2000 with respect to the carrier table 321 when the carrier plate assembly 320 moves, thereby ensuring the position accuracy during laser marking. After the laser marking is completed at the processing station G22, the carrier plate assembly 320 moves from the processing station G22 to the unloading station G23. After reaching the unloading station G23, the first lifting drive member 323 drives the first magnetic attraction member 322 to lower, so as to release the limit on the battery product 2000.

[0030] For example Figure 5 Figure 5 , in some embodiments, at least a part of the carrier table 321 is a transparent area. The turntable assembly 300 further includes a backlight 330. The backlight 330 is fixedly installed below the carrier table 321 located at the loading station G21, and the light emitted by the backlight 330 can pass through the transparent area of the carrier table 321. By providing the backlight 330, when the second camera 420 performs position positioning and angle positioning on the battery product 2000 located at the loading station G21, the image collected by the second camera 420 has a clearer contour, thereby facilitating the improvement of positioning accuracy.

[0031] For example Figure 5, in some embodiments, the carrier 321 includes a non-translucent carrier frame 3211 and a glass plate 3212. The glass plate 3212 is detachably embedded in the carrier frame 3211, and the glass plate 3212 corresponds to the transparent area.

[0032] In the above embodiment, the glass plate 3212 is detachably embedded in the carrier frame 3211. When the surface of the glass plate 3212 becomes uneven or the light transmittance deteriorates due to friction, it is convenient to replace the glass plate 3212, improving the convenience of maintaining the carrier 321.

[0033] Such as Figure 5 , in some embodiments, each carrier disk assembly 320 further includes a guide seat 324, a connection block 325, a guide post 326, and a buffer elastic member 327. The guide seat 324 is fixedly connected to the carrier 321, and a guide hole is provided on the guide seat 324. The connection block 325 is connected to the first lifting driving member 323, and the first lifting driving member 323 can drive the connection block 325 to move up and down. The guide post 326 is fixedly connected to the connection block 325, the guide post 326 passes through the guide hole, and the first magnetic member 322 is connected to the connection block 325 and / or the guide post 326. The buffer elastic member 327 is connected between the connection block 325 and the guide seat 324.

[0034] By providing the buffer elastic member 327, when the first lifting driving member 323 drives the first magnetic member 322 to move up and down, it can provide buffering for the movement of the first magnetic member 322, avoiding the loss of the first magnetic member 322 or the carrier 321 caused by the rigid impact between the first magnetic member 322 and the carrier 321.

[0035] Such as Figure 4 , in some embodiments, the feeding and conveying assembly 200 includes a first conveyor belt 210, a first baffle 220, a second baffle 230, and a baffle adjusting mechanism 240.

[0036] The first conveyor belt 210 is used to convey the battery product 2000, and the feeding-in place station G11 is located at one end of the first conveyor belt 210. In this embodiment, the first conveyor belt 210 extends along the second direction Y. The second direction Y is perpendicular to the first direction X.

[0037] The first baffle 220 and the second baffle 230 are located on the side where the upper surface of the first conveyor belt 210 is located. The first baffle 220 and the second baffle 230 are oppositely arranged on both sides of the conveying direction of the first conveyor belt 210. The interval between the first baffle 220 and the second baffle 230 is used to define the size of the battery product 2000 that can be conveyed through on the first conveyor belt 210.

[0038] The baffle adjustment mechanism 240 is connected to the first baffle 220 and the second baffle 230. The baffle adjustment mechanism 240 is used to adjust the interval between the first baffle 220 and the second baffle 230. In one example, the baffle adjustment mechanism 240 includes a right - hand and left - hand screw adjustment mechanism, which can simultaneously adjust the first baffle 220 and the second baffle 230 to move towards each other or away from each other.

[0039] In the above - mentioned embodiment, since the interval between the first baffle 220 and the second baffle 230 is used to define the size of the battery products 2000 that can be transported through on the first conveyor belt 210, and the interval between the first baffle 220 and the second baffle 230 is adjustable, the first conveyor belt 210 can be compatible with transporting battery products 2000 of different sizes.

[0040] Such as Figure 4 , in some embodiments, the feeding and conveying assembly 200 further includes a product blocking mechanism 250. The product blocking mechanism 250 includes a reciprocating driving member 251 and a blocking member 252. The blocking member 252 is disposed at the feeding - in place station G11 and is located on the downstream side of the feeding - in place station G11 along the conveying direction of the first conveyor belt 210. The reciprocating driving member 251 is connected to the blocking member 252, and the reciprocating driving member 251 can drive the blocking member 252 to move along a direction parallel to the conveying direction of the first conveyor belt 210.

[0041] In the above - mentioned embodiment, each battery product 2000 that reaches the feeding - in place station G11 on the first conveyor belt 210 will abut against the blocking member 252. Since the reciprocating driving member 251 can drive the blocking member 252 to move along a direction parallel to the conveying direction of the first conveyor belt 210, the position of the blocking member 252 is adjustable, so as to ensure that when the feeding and conveying assembly 200 switches to transporting another size of battery product 2000, the center position of the battery product 2000 at the feeding - in place station G11 is still at the preset position, which is convenient for ensuring the stable handling of battery products 2000 of different sizes by the loading manipulator 600.

[0042] Such as Figure 6 , in some embodiments, the vision and laser marking assembly 400 further includes a lifting seat 440 and a focusing driving member 450. The first camera 410, the second camera 420 and the laser marking head 430 are installed on the lifting seat 440. The focusing driving member 450 is connected to the lifting seat 440, and the focusing driving member 450 is used to drive the lifting seat 440 to move up and down.

[0043] By setting the focusing driving member 450, the vision and laser marking assembly 400 can be compatible with automatically focusing on battery products 2000 of different thicknesses, ensuring the accuracy of image acquisition and positioning by the first camera 410 and the second camera 420, and also ensuring the accuracy of laser marking by the laser marking head 430.

[0044] Figure 7 This is a three-dimensional schematic diagram of the loading manipulator in an embodiment of the laser marking machine of the present invention.
