[0003] The present application relates to the field of battery technology, and in particular to a coding device and battery processing equipment. Background Art

[0004] After battery production is complete, a code needs to be engraved on the battery surface to record the battery's information. Currently, laser engraving is commonly used for battery coding. However, due to the high positioning accuracy required for the working area, laser engraving has limited its application in industry. Alternatively, laser engraving can result in low production efficiency, which in turn affects overall battery production efficiency.

[0005] Summary of the Invention

[0006] Based on this, it is necessary to provide a coding device and battery processing equipment to address the problem of low production efficiency when coding batteries.

[0007] In the first aspect, the present application provides a coding device for engraving on a battery, the coding device comprising a base, a moving mechanism and a coding assembly, the base having a carrying position for carrying a battery to be engraved; the moving mechanism being movably disposed on the base; the coding assembly being disposed on the moving mechanism and being used to perform coding operations on the battery; the coding assembly comprising a laser and a dust hood disposed on the laser, a laser channel for passing the laser being formed inside the dust hood, and when the coding assembly performs the coding operation, the laser channel is connected between the battery and the laser; a dust suction port connected to the laser channel is provided on the dust hood; wherein the moving mechanism is configured to be able to drive the coding assembly to move along a first direction, a second direction and a third direction, and the first direction, the second direction and the third direction are arranged to intersect in pairs.

[0008] Through the above structure, the support position can support and position the battery. The moving mechanism drives the engraving assembly to move relative to the battery in the first, second, and third directions, respectively, achieving automatic positioning between the engraving assembly and the battery. This enables the engraving assembly to more accurately perform the engraving operation on the battery, improving the accuracy and efficiency of the engraving process. The dust collection hood can be provided to promptly exhaust smoke and dust from the laser channel, keeping the laser channel clean and the laser energy stable, thereby achieving better laser engraving results.

[0009] In some embodiments, the moving mechanism includes a first moving assembly movably disposed on the base along a first direction, the first moving assembly being connected to the code engraving assembly and configured to drive the code engraving assembly to move along the first direction;

[0010] The moving mechanism includes a second moving assembly movably arranged on the first moving assembly along the second direction, the second moving assembly is connected to the code engraving assembly, and is used to drive the code engraving assembly to move along the second direction;

[0011] The moving mechanism comprises a third moving component movably arranged on the second moving component along the third direction. The third moving component is connected to the code engraving component and is used for driving the code engraving component to move along the third direction.

[0012] By setting a first movable component, a second movable component, and a third movable component, the code engraving component can be driven to move along the first direction, the second direction, and the third direction respectively, thereby adjusting the position of the code engraving component in the first direction, the second direction, and the third direction so that the code engraving component can correspond to the position of the battery on the supporting position.

[0013] In some embodiments, the direction in which the laser emits laser light is set along a third direction; the coding device further includes a rangefinder, which is used to measure the distance between the laser and the battery on the supporting position in the third direction.

[0014] Through the above structure, the distance between the laser and the battery on the supporting position in the third direction can be adjusted more accurately, so that the laser coding effect on the battery is better.

[0015] In some embodiments, the coding device further includes a conveying mechanism, which extends along the first direction and passes through the carrying position to convey the battery to be coded along the first direction.

[0016] By providing a conveying mechanism, multiple batteries can be driven to move along the first direction at the same time, and the batteries can be continuously conveyed to the carrying position, thereby improving the production efficiency of the coding process.

[0017] In some embodiments, the conveying mechanism includes a lifting assembly, which is used to lift the battery on the supporting position.

[0018] By setting up the lifting assembly, the battery transportation and the battery coding operation on the supporting position can be carried out simultaneously, thereby further improving the battery production efficiency.

[0019] In some embodiments, the lifting assembly includes a driving member and a lifting member, the lifting member having an inclined surface and a supporting surface, the inclined surface is inclined along the vertical direction, and the supporting surface is horizontally arranged and connected to the top of the inclined surface;

[0020] The driving member is used to drive the battery to climb from the inclined surface to the supporting surface.

[0021] By providing a driving member and a lifting member, the battery can be moved from the conveyor belt to the support surface, thereby removing the battery from the conveyor belt and achieving laser coding on the battery without affecting the continued conveyance of the conveyor belt. In addition, the lifting member cooperates with the driving member through the inclined surface and the support surface to achieve vertical lifting of the battery, which can save vertical installation space and make the overall structure of the coding device more compact, taking up less space.

[0022] In some embodiments, the lifting assembly further includes a tray for carrying batteries, and a positioning piece is protruding from a surface of the tray facing the battery. The positioning piece is used to be inserted into a positioning hole on the battery to position the battery during the lifting process.

[0023] Therefore, during the lifting process of the battery carrier and the battery, the battery carrier and the battery can be stably supported on the tray through the plug-in cooperation between the positioning members and the positioning holes, making the battery more stable during the lifting process.

[0024] In some embodiments, the positioning member is retractably arranged on the tray along its protruding direction. Through the above structure, the positioning member can be more flexibly controlled to be inserted into or removed from the positioning hole, thereby realizing the plug-in and separation between the tray and the battery.

[0025] In some embodiments, the base includes a base body and a frame body disposed on the base body, and the moving mechanism is movably disposed on the frame body.

[0026] Thus, the frame is mounted on the base, and the frame can be placed above the supporting position. Then, the moving mechanism is movably arranged on the frame, and when the moving mechanism moves on the frame, the distance between the code engraving component and the battery on the supporting position can be adjusted.

[0027] In some embodiments, the frame includes a first beam, a second beam, and a third beam connected to each other. The first beam extends along a first direction, the second beam extends along a second direction, and the third beam extends along a third direction.

[0028] With the above structure, the moving mechanism can be flexibly arranged on any one of the first beam, the second beam or the third beam according to actual use conditions, so as to better adjust the moving position of the code engraving component.

[0029] In some embodiments, the coding device further includes a control component that is in communication with the mobile mechanism and the coding component and is used to control the opening and closing of the mobile mechanism and the coding component. By providing the control component, the battery coding process can be automatically performed, thereby improving the efficiency of the coding process.

[0031] When the above-mentioned coding device and battery processing equipment engrave a battery, the battery is first positioned in a supporting position, and then the coding component is driven by the moving component to move in three different directions: a first direction, a second direction, and a third direction, thereby adjusting the position of the coding component relative to the battery on the supporting position in three-dimensional space, so that the coding component can perform the coding operation on the battery more accurately, thereby improving the accuracy and efficiency of the coding process.

[0046] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric vehicles, as well as in other fields. As the application of power batteries continues to expand, market demand is also growing.

[0047] A battery cell is the smallest unit that makes up a battery. After one or more battery cells are assembled to form a battery, various information such as the model and production date of each battery needs to be reflected on the external surface of the battery to facilitate quick identification and differentiation during subsequent transportation or use.

[0048] Currently, laser engraving is commonly used to engrave information on the outer surface of batteries. However, due to the high positioning accuracy required for the working area, laser engraving's current industrial application is still significantly limited. As a result, the production process efficiency of laser engraving is generally low, resulting in lower overall battery production efficiency.

[0049] Based on the above considerations, in order to solve the current problem of low production efficiency when coding batteries, one or more embodiments of the present application provide an engraving device. When coding a battery, the battery is first positioned at a supporting position, and then the engraving component is driven by a moving component to move in three different directions: a first direction, a second direction, and a third direction. The position of the engraving component relative to the battery on the supporting position is adjusted in three-dimensional space, so that the engraving component can perform the engraving operation on the battery more accurately, thereby improving the accuracy and efficiency of the coding process.

[0050] Referring to Figures 1, 2, and 3, one embodiment of the present application provides a coding device 100 for coding batteries. The coding device 100 includes a base 10, a movable mechanism 20, and a coding assembly 30. The base 10 has a support 11 for supporting the battery to be coded. The movable mechanism 20 is movably mounted on the base 10. The coding assembly 30 is mounted on the movable mechanism 20 and is configured to perform coding operations on the battery. The movable mechanism 20 is configured to drive the coding assembly 30 to move along a first direction a, a second direction b, and a third direction c, with the first direction a, the second direction b, and the third direction c intersecting with each other.

[0051] It should be noted that the battery can be an integral structure composed of one or more battery cells connected in series, parallel or mixed, or it can be an integral structure composed of one or more battery cells connected in series, parallel or mixed to form a battery module, and then multiple battery modules are combined.

[0052] The supporting position 11 on the base 10 can support and position the battery to be engraved, that is, fix the position of the supporting position 11, and then position the battery to be engraved by placing it on the supporting position 11.

[0053] The engraving assembly 30 is the component that engraves the battery, and the moving mechanism 20 is the structure that drives the engraving assembly 30 relative to the battery. The engraving assembly 30 is mounted on the moving mechanism 20. As the moving mechanism 20 moves relative to the base 10, it drives the engraving assembly 30 to move synchronously, thereby changing the position of the engraving assembly 30 relative to the battery. This allows the engraving assembly 30 to align with the desired location on the battery and accurately engrave the battery.

[0054] Specifically, the first direction a, the second direction b, and the third direction c are arranged perpendicularly to each other. The first direction a can be set as a first horizontal direction, the second direction b can be set as a vertical direction, and the third direction c can be set as a second horizontal direction perpendicular to the first horizontal direction.

[0055] During battery marking, the battery is first placed on the support 11. The moving mechanism 20 is then controlled to sequentially move the marking assembly 30 in the first direction a, the second direction b, and the third direction c. This adjusts the position of the marking assembly 30 relative to the battery on the support 11, aligning the marking assembly 30 with the area of ​​the battery to be marked and ensuring an optimal marking distance from the battery. At this point, the marking assembly 30 is controlled to perform marking operations on the battery on the support 11.

[0056] Through the above structure, the supporting position 11 can support and position the battery, and the moving mechanism 20 drives the coding component 30 to move relative to the battery along the first direction a, the second direction b and the third direction c respectively, so as to realize automatic positioning between the coding component 30 and the battery, so that the coding component 30 can perform coding operations on the battery more accurately, thereby improving the accuracy and efficiency of the coding process.

[0057] In some embodiments, the moving mechanism 20 includes a first moving component 21 movably disposed on the base 10 along a first direction a. The first moving component 21 is connected to the code engraving component 30 and is used to drive the code engraving component 30 to move along the first direction a.

[0058] Specifically, the first direction a can be set to a first horizontal direction, and the coding component 30 is set on the first movable component 21. The coding component 30 is driven to move along the first horizontal direction by the first movable component 21 to adjust the position of the coding component 30 relative to the battery on the supporting position 11 in the first horizontal direction, so that the coding component 30 can correspond to the position of the battery on the supporting position 11 in the first horizontal direction.

[0059] Furthermore, the first moving component 21 may include a first body and a first driving cylinder. The first body is movably disposed on the base 10. The coding component 30 is disposed on the first body, and the first body and the coding component 30 thereon are driven to move along the first horizontal direction by the first driving cylinder to adjust the position of the coding component 30 in the first horizontal direction.

[0060] It is understood that the first moving assembly 21 can also be configured as other moving mechanisms, such as a screw assembly, and the code engraving assembly 30 is disposed on the screw assembly, and the code engraving assembly 30 is driven by the screw assembly to move along the first direction a. The first moving assembly 21 can also be configured as other moving mechanisms such as a slider and a slide rail, which will not be described in detail here.

[0061] By setting the first moving component 21, the code engraving component 30 can be driven to move along the first direction a, thereby adjusting the position of the code engraving component 30 in the first direction a so that the code engraving component 30 can correspond to the position of the battery on the supporting position 11 in the first direction a.

[0062] In some embodiments, the moving mechanism 20 further includes a second moving component 22 movably disposed on the first moving component 21 along the second direction b. The second moving component 22 is connected to the code engraving component 30 and is used to drive the code engraving component 30 to move along the second direction b.

[0063] Specifically, the second direction b can be set to a vertical direction, and the code engraving assembly 30 is disposed on the second movable assembly 22 and is indirectly disposed on the first movable assembly 21 through the second movable assembly 22. The code engraving assembly 30 is driven by the second movable assembly 22 to move in the vertical direction to adjust the position of the code engraving assembly 30 relative to the battery on the supporting position 11 in the vertical direction, so that the code engraving assembly 30 can correspond to the position of the battery on the supporting position 11 in the vertical direction.

[0064] After placing the battery on the carrier 11, the first movable assembly 21 is first controlled to move in the first horizontal direction, thereby driving the code engraving assembly 30 to move in the first horizontal direction. When the position of the code engraving assembly 30 in the first horizontal direction corresponds to the position of the battery on the carrier 11, the first movable assembly 21 is controlled to stop moving.

[0065] Then, the second moving assembly 22 is controlled to move vertically relative to the first moving assembly 21 , thereby driving the code engraving assembly 30 to move vertically, so that the code engraving assembly 30 can be at the same height as the battery on the supporting position 11 in the vertical direction.

[0066] Furthermore, the second movable component 22 may include a second body and a second driving cylinder. The second body may be movably arranged on the first body of the first movable component 21. The coding component 30 is arranged on the second body, and the second body and the coding component 30 thereon are driven to move in the vertical direction by the second driving cylinder to adjust the position of the coding component 30 in the vertical direction.

[0067] It is understood that the second moving assembly 22 can also be configured as other moving mechanisms, such as a screw assembly, and the code engraving assembly 30 is disposed on the screw assembly, and the code engraving assembly 30 is driven by the screw assembly to move along the second direction b. The second moving assembly 22 can also be configured as other moving mechanisms such as a slider and a slide rail, which will not be described in detail here.

[0068] By setting the second moving component 22, the code engraving component 30 can be driven to move along the second direction b, thereby adjusting the position of the code engraving component 30 in the second direction b so that the code engraving component 30 can correspond to the position of the battery on the supporting position 11 in the second direction b.

[0069] In some embodiments, the moving mechanism 20 further includes a third moving component 23 movably disposed on the second moving component 22 along the third direction c. The third moving component 23 is connected to the code engraving component 30 and is used to drive the code engraving component 30 to move along the third direction c.

[0070] Specifically, the third direction c can be set as a second horizontal direction and is perpendicular to the first horizontal direction. The code engraving assembly 30 is disposed on the third movable assembly 23 and is indirectly disposed on the second movable assembly 22 via the third movable assembly 23. The third movable assembly 23 drives the code engraving assembly 30 to move along the second horizontal direction to adjust the position of the code engraving assembly 30 relative to the battery on the support position 11 in the second horizontal direction, so that the code engraving assembly 30 can correspond to the position of the battery on the support position 11 in the second horizontal direction.

[0071] After placing the battery on the carrier 11, the first movable assembly 21 is first controlled to move in the first horizontal direction, thereby driving the code engraving assembly 30 to move in the first horizontal direction. When the position of the code engraving assembly 30 in the first horizontal direction corresponds to the position of the battery on the carrier 11, the first movable assembly 21 is controlled to stop moving.

[0072] Then, the second movable assembly 22 is controlled to move vertically relative to the first movable assembly 21, thereby driving the code engraving assembly 30 to move vertically. When the code engraving assembly 30 is at the same height as the battery on the supporting position 11 in the vertical direction, the second movable assembly 22 is controlled to stop moving.

[0073] Furthermore, the third movable assembly 23 is controlled to move relative to the second movable assembly 22 in the second horizontal direction, thereby driving the code engraving assembly 30 to move in the second horizontal direction. Thus, by moving in three directions perpendicular to each other in three-dimensional space, the code engraving assembly 30 is ultimately aligned with the battery on the carrier 11. At this point, the code engraving assembly 30 is activated to accurately engrave the battery on the carrier 11.

[0074] The third movable assembly 23 may include a third body and a third driving cylinder. The third body may be movably disposed on the second body of the second movable assembly 22. The coding assembly 30 is disposed on the third body, and the third body and the coding assembly 30 thereon are driven to move along the second horizontal direction by the third driving cylinder to adjust the position of the coding assembly 30 in the second horizontal direction.

[0075] It is understood that the third moving assembly 23 can also be configured as other moving mechanisms, such as a screw assembly, and the code engraving assembly 30 is disposed on the screw assembly, and the code engraving assembly 30 is driven by the screw assembly to move along the third direction c. The third moving assembly 23 can also be configured as other moving mechanisms such as a slider and a slide rail, which will not be described in detail here.

[0076] By setting the third moving component 23, the coding component 30 can be driven to move along the third direction c, thereby adjusting the position of the coding component 30 in the third direction c, so that the coding component 30 can correspond to the position of the battery on the supporting position 11 in the third direction c, and finally achieve the purpose of aligning the coding component 30 with the battery on the supporting position 11 to perform the coding operation on the battery.

[0077] In some embodiments, the coding assembly 30 includes a laser 31, and the direction of the laser 31 emitting laser light is set along the third direction C. The coding device 100 also includes a rangefinder (not shown in the figure), which is used to measure the distance between the laser 31 and the battery on the carrier 11 in the third direction C.

[0078] Specifically, the laser 31 is a component that can emit laser light and use the laser light to perform laser marking on the battery. The laser 31 is disposed on the third body of the third moving assembly 23, and the laser emission direction of the laser 31 is set along the third direction c.

[0079] The rangefinder refers to a component that can measure the distance between the laser 31 and the battery on the support position 11 along the third direction c. The rangefinder is installed on the third body, and the rangefinder measures the distance between the laser 31 and the battery on the support position 11 in the third direction c. Among them, a target distance can be preset in advance, that is, a distance that obtains a better effect of laser engraving. If the actual measured distance is greater than the target distance, the third moving component 23 is controlled to drive the engraving component 30 to move in the direction close to the battery. If the actual measured distance is less than the target distance, the third moving component 23 is controlled to drive the engraving component 30 to move in the direction away from the battery. In this way, the distance between the engraving component 30 and the battery in the third direction c meets the target distance.

[0080] Through the above structure, the distance between the laser 31 and the battery on the carrier position 11 in the third direction c can be adjusted more accurately, so that the laser engraving effect of the laser 31 on the battery is better.

[0081] As shown in Figures 3 and 4, in some embodiments, the code engraving assembly 30 further includes a dust collection hood 32 disposed on the laser 31. A laser channel 321 is formed inside the dust collection hood 32 for the laser to pass through. When the code engraving assembly 30 performs a code engraving operation, the laser channel 321 communicates between the battery and the laser 31. The dust collection hood 32 defines a dust collection port 322 that communicates with the laser channel 321 and is used to exhaust dust within the laser channel 321.

[0082] It should be noted that during the laser engraving process, a large amount of smoke and dust will be generated. These smoke and dust will gradually gather and form a certain obstruction on the light output path of the laser 31, weakening the laser energy and thus affecting the effect of the laser engraving.

[0083] For this purpose, a dust hood 32 is provided on the laser 31 and is positioned in the light path of the laser light emitted by the laser 31. When the marking assembly 30 is performing the marking operation, the dust hood 32 is positioned between the laser 31 and the surface of the battery to be marked, and the dust hood 32 and the surface of the battery to be marked are in contact with each other.

[0084] At this point, a laser channel 321 is formed inside the dust cover 32. The two ends of the laser channel 321 connect the laser 31 to the surface of the battery to be engraved. The laser 31 is turned on, and laser light is emitted along the laser channel 321, thereby striking the surface of the battery to be engraved, thereby completing the engraving operation.

[0085] At the same time, smoke and dust are formed in the laser channel 321. A vacuum cleaner is connected to the dust suction port 322 on the dust cover 32, and the vacuum cleaner is turned on to collect the smoke and dust in the laser channel 321, so that the smoke and dust can be discharged from the laser channel 321 in time to keep the laser channel 321 clean.

[0086] By providing the dust hood 32, smoke and dust in the laser channel 321 can be discharged in time, the laser channel 321 can be kept clean, the laser energy can be kept stable, and the laser engraving effect can be better.

[0087] Please refer to FIG. 1 and FIG. 5 . In some embodiments, the marking device 100 further includes a conveying mechanism 40 . The conveying mechanism 40 extends along the first direction a and passes through the supporting position 11 to convey the batteries to be marked along the first direction a.

[0088] Specifically, the conveying mechanism 40 may include a conveyor belt extending along the first direction a and passing through the carrying position 11. A plurality of batteries are placed on the conveyor belt at intervals along the first direction a, and the conveyor belt drives the batteries to move along the first direction a.

[0089] By providing the conveying mechanism 40 , multiple batteries can be driven to move along the first direction a at the same time, and the batteries can be continuously conveyed to the carrying position 11 , thereby improving the production efficiency of the coding process.

[0090] As shown in FIG. 1 and FIG. 6 , in some embodiments, the conveying mechanism 40 includes a lifting assembly 41 , and the lifting assembly 41 is used to lift the battery on the carrying position 11 .

[0091] Specifically, the lifting assembly 41 can be set on the base 10. When one of the batteries on the conveyor belt moves to the position of the carrying position 11, the lifting assembly 41 lifts the battery upward from the conveyor belt to a certain height, so that the battery can be detached from the conveyor belt and laser engraved on the carrying position 11.

[0092] At this time, the conveyor belt does not need to stop and can continue to transport other batteries.

[0093] By providing the lifting assembly 41 , the battery transportation and the battery coding operation on the carrying position 11 can be carried out simultaneously, thereby further improving the battery production efficiency.

[0094] In some embodiments, the lifting assembly 41 includes a driving member 411 and a lifting member 412. The lifting member 412 has an inclined surface 413 and a supporting surface 414. The inclined surface 413 is inclined in the vertical direction, and the supporting surface 414 is horizontally arranged and connected to the top of the inclined surface 413. The driving member 411 is used to drive the battery to climb from the inclined surface 413 to the supporting surface 414.

[0095] Specifically, the driving member 411 can be configured as a driving cylinder and can be movably arranged along the third direction c, that is, the second horizontal direction. Thus, the driving member 411 can push the batteries on the conveyor belt onto the lifting member 412 along the second horizontal direction.

[0096] Furthermore, the driving member 411 pushes the battery on the conveyor belt onto the inclined surface 413 along the second horizontal direction, and then continues to push the battery along the inclined surface 413, so that the battery can move upward along the inclined surface 413 until the battery moves to the horizontally arranged support surface 414 and is fixed on the support surface 414.

[0097] Thus, when the batteries on the conveyor belt move to the position corresponding to the carrying position 11, the driving member 411 pushes the batteries on the conveyor belt onto the inclined surface 413 along the second horizontal direction, and pushes the batteries up along the inclined surface 413 to the support surface 414. Then, the moving mechanism 20 drives the coding assembly 30 to move in the first direction a, the second direction b, and the third direction c in sequence, so that the laser 31 is aligned with the battery and performs the laser coding operation.

[0098] By providing a driving member 411 and a lifting member 412, the battery can be moved from the conveyor belt to the support surface 414, thereby removing the battery from the conveyor belt and achieving laser coding of the battery without affecting the continued conveyance of the conveyor belt. In addition, the lifting member 412 cooperates with the driving member 411 through the inclined surface 413 and the support surface 414 to achieve vertical lifting of the battery, which can save vertical installation space and make the overall structure of the coding device 100 more compact and take up less space.

[0099] In some embodiments, the lifting assembly 41 also includes a tray 415 for supporting batteries. A positioning member 416 is protruding from the surface of the tray 415 facing the battery. The positioning member 416 is used to be inserted into the positioning hole on the battery to position it during the lifting process of the battery.

[0100] It should be noted that in order to make the battery transportation and movement process more stable, the battery is usually placed on a battery carrier, and the battery and the battery carrier are moved simultaneously as a whole.

[0101] Specifically, the batteries are placed on a battery carrier, which is then placed together on a tray 415. A positioning member 416 is protruding from the top surface of the tray 415. The positioning member 416 can be, but is not limited to, a latch. A positioning hole is provided on the bottom surface of the battery carrier to mate with the latch.

[0102] Before the driver 411 drives the battery and battery carrier to lift, the latch on the tray 415 is first inserted into the positioning hole on the battery carrier, so that the tray 415 and the battery carrier are plugged and matched, and the two can be stably connected. The driver 411 is then controlled to push the tray 415, the battery carrier, and the batteries thereon to climb along the inclined surface 413 to the support surface 414, and finally fixed on the support surface 414.

[0103] Therefore, during the lifting process of the battery carrier and the battery, the battery carrier and the battery can be stably supported on the tray 415 through the plug-in cooperation between the positioning member 416 and the positioning hole, making the battery more stable during the lifting process.

[0104] In some embodiments, the positioning member 416 is retractably disposed on the tray 415 along its protruding direction.

[0105] Specifically, the latch is retractably mounted on the tray 415 in a vertical direction. Prior to insertion, the latch is retracted. Before lifting the battery, the latch is extended upward to allow it to smoothly insert into the positioning hole on the bottom surface of the battery carrier, completing the insertion and engagement between the two.

[0106] Through the above structure, the positioning member 416 can be more flexibly controlled to be inserted into or removed from the positioning hole, thereby realizing the plug-in fit and separation between the tray 415 and the battery.

[0107] Please refer to FIG. 1 again. In some embodiments, the base 10 includes a base 12 and a frame 13 disposed on the base 12 . The moving mechanism 20 is movably disposed on the frame 13 .

[0108] Specifically, the base 12 serves as a support and mounting base. The frame 13 is mounted on the base 12 and positioned over the support 11. The movable mechanism 20 is then movably mounted on the frame 13. As the movable mechanism 20 moves on the frame 13, it adjusts the distance between the code engraving assembly 30 and the battery on the support 11.

[0109] In some embodiments, the frame 13 includes a first beam 131, a second beam 132 and a third beam 133 connected to each other. The first beam 131 extends along a first direction a, the second beam 132 extends along a second direction b, and the third beam 133 extends along a third direction c.

[0110] Specifically, the first beam 131 , the second beam 132 and the third beam 133 are vertically arranged in pairs and together form a rectangular frame, thereby covering the supporting position 11 .

[0111] With the above structure, the moving mechanism 20 can be flexibly arranged on any one of the first beam 131 , the second beam 132 or the third beam 133 according to actual use conditions, so as to better adjust the moving position of the code engraving assembly 30 .

[0112] In some embodiments, the coding device 100 further includes a control component (not shown in the figure), which is respectively connected to the moving mechanism 20 and the coding component 30 for controlling the opening and closing of the moving mechanism 20 and the coding component 30.

[0113] Specifically, the control component can be configured as a controller, which is respectively connected to the first moving component 21, the second moving component 22, the third moving component 23 and the laser 31. In addition, the controller can also be connected to the rangefinder and the lifting component 41.

[0114] The controller first controls the lifting assembly 41 to lift the batteries on the conveyor belt, separating them from the conveyor belt. The controller then controls the first moving assembly 21 to move the code engraving assembly 30 in a first direction a, the second moving assembly 22 to move the code engraving assembly 30 in a second direction b, and the third moving assembly 23 to move the code engraving assembly 30 in a third direction c.

[0115] Furthermore, the controller controls the rangefinder to turn on, measure the distance between the laser 31 and the battery, and feed the measurement result back to the controller. The controller controls the third moving component 23 to move a corresponding distance based on the measurement result to adjust the distance between the laser 31 and the battery.

[0116] Then, the controller controls the laser 31 to turn on and perform a coding operation on the battery.

[0117] By setting the control component, the automatic coding process of the battery can be realized, thereby improving the working efficiency of the coding process.

[0118] Based on the same concept as the above-mentioned coding device 100 , the present application also provides a battery processing device, including the above-mentioned coding device 100 .

[0119] According to one or more embodiments, a plurality of batteries are first conveyed sequentially along a first direction a by a conveyor belt. When one of the batteries moves to a position corresponding to the loading position 11, the positioning member 416 is first controlled to protrude upward and insert into the positioning hole on the bottom surface of the battery carrier, thereby stably connecting the battery carrier to the tray 415.

[0120] Then, the driving member 411 is controlled to push the batteries on the conveyor belt onto the inclined surface 413 , and the batteries gradually climb along the inclined surface 413 to the support surface 414 , and are finally fixed on the support surface 414 .

[0121] Furthermore, the controller controls the first moving component 21 to drive the coding component 30 to move along the first horizontal direction. When the position of the coding component 30 in the first horizontal direction corresponds to the battery on the supporting position 11, the controller controls the second moving component 22 to drive the coding component 30 to move along the vertical direction, so that the coding component 30 and the battery on the supporting position 11 are at the same height.

[0122] At this point, the controller controls the third movable assembly 23 to move the marking assembly 30 in the second horizontal direction, moving the marking assembly 30 closer to or further away from the battery on the support position 11. Simultaneously, the controller activates the rangefinder and measures the distance between the laser 31 and the battery on the support position 11 in the second horizontal direction. When the measurement meets the target distance, the controller controls the third movable assembly 23 to stop moving and activates the laser 31 to laser engrave the battery.

[0123] While laser engraving is being performed, the vacuum cleaner connected to the suction port 322 is turned on. The vacuum cleaner sucks out the smoke and dust in the laser channel 321 through the suction port 322, thereby keeping the laser channel 321 clean and achieving a better effect of laser engraving.

[0124] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0125] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
