Conventionally, rust prevention of solder printing is achieved by a jacket film process, i.e., an insulating film is coated on the outer peripheral surface of a case by means of heat shrinkage. The adoption of the film sleeving technology has the following defects: firstly, the end part of the battery cannot be covered by an insulating film, so that the welding and printing of the end surface is difficult to protect; secondly, the laminating efficiency is lower, can only match the production beat of high-speed production line through the mode that increases the laminating station, leads to equipment occupation space big, and equipment cost is higher.

Referring to fig. 1, an embodiment of the present utility model provides a spraying apparatus, which includes a loading mechanism 30, a driving mechanism 20, and a spraying mechanism 50. The loading mechanism 30 is used for loading the battery a (see fig. 2) and controllably rotates the battery a about its own axis. The drive mechanism 20 is coupled to the loading mechanism 30 such that the drive mechanism 20 is capable of driving the loading mechanism 30 through a spraying station (not shown). The spraying mechanism 50 is arranged corresponding to the spraying station. When the driving mechanism 20 drives the loading mechanism 30 to reach the spraying station, the loading mechanism 30 drives the battery A thereon to rotate around the axis of the loading mechanism, and the spraying mechanism 50 sprays the surface of the battery A to form a protective layer.

In actual use, the above-described spraying device first loads the battery a onto the loading mechanism 30. The drive mechanism 20 then drives the loading mechanism 30 to move to the spraying station. At the spraying station, the loading mechanism 30 drives the battery a thereon to rotate about its own axis. The spraying mechanism 50 sprays the surface of the battery a during the rotation of the battery a around the axis thereof to form a protective layer on the surface of the battery a. After the spraying is completed, the drive mechanism 20 drives the loading mechanism 30 to continue downstream.

In this way, the surface of the battery a is sprayed with the protective layer by the cooperation of the loading mechanism 30, the driving mechanism 20, and the spraying mechanism 50. The protective layer is used for protecting the welding marks on the surface of the battery A, so that the welding marks are prevented from rusting, and meanwhile, the effect of insulating the surface of the battery can be achieved. Compared with the prior art adopting a film coating process, the application adopts a spraying process, can realize the protection of welding marks on the peripheral side outer wall of the battery A and welding marks on the end surface, can match the production takt of a high-speed production line, and greatly improves the production efficiency.

In the embodiment of the application, two spraying stations are provided, and the two spraying stations are a first spraying station a3 and a second spraying station a4 respectively. The drive mechanism 20 is capable of driving the loading mechanism 30 to sequentially pass through the first spraying station a3 and the second spraying station a4. The painting mechanism 50 includes a first painting assembly 51 disposed corresponding to the first painting station a3 and a second painting assembly 52 disposed corresponding to the second painting station a4.

When the loading mechanism 30 reaches the first spraying station a3, the loading mechanism 30 drives the battery a to rotate around its own axis, and the first spraying assembly 51 sprays the end face of the battery a (i.e., the top end face of the battery a in fig. 2) and forms a protective layer. When the loading mechanism 30 reaches the second spraying station a4, the loading mechanism 30 drives the battery a to rotate around the axis of the loading mechanism, and the second spraying assembly 52 sprays the peripheral outer wall of the battery a and forms a protective layer. In this way, a protective layer is formed on the end face of the battery A by spraying so as to protect the welding marks on the end face of the battery A; the protective layer is formed on the peripheral outer wall of the battery A by spraying so as to protect the welding marks on the peripheral outer wall of the battery A.

It should be noted that, in other embodiments, when the loading mechanism 30 reaches the first spraying station a3, the loading mechanism 30 drives the battery a to rotate around its own axis, and the first spraying component 51 sprays the peripheral outer wall of the battery a and forms a protective layer. When the loading mechanism 30 reaches the second spraying station a4, the loading mechanism 30 drives the battery a to rotate around the axis of the loading mechanism, and the second spraying assembly 52 sprays the end face of the battery a and forms a protective layer.

The protective layer on the peripheral outer wall of battery a may cover a part of the peripheral outer wall or may cover the whole peripheral outer wall, and is not limited thereto. When the protective layer covers all of the peripheral side outer walls of the battery a, the protective layer also has an insulating effect on the peripheral side outer walls of the battery a because the protective layer is made of an insulating material.

Referring to fig. 2, in particular to the embodiment, the spraying apparatus further includes a first curing light 80 disposed corresponding to the first spraying station a 3. The first curing lamp 80 is used to irradiate the protective layer sprayed on the battery a by the first spraying assembly 51, and the protective layer is gradually cured under the irradiation of the ultraviolet light emitted from the first curing lamp 80. The material of the protective layer is UV ink, and is cured to form a UV film after being irradiated by ultraviolet light emitted from the first curing lamp 80.

Referring to fig. 3, in particular to the embodiment, the spraying apparatus further includes a second curing lamp 81 disposed corresponding to the second spraying station a 4. The second curing lamp 81 is used to irradiate the protective layer sprayed on the battery a by the second spraying assembly 52, and the protective layer is gradually cured under irradiation of ultraviolet light emitted from the second curing lamp 81. The material of the protective layer is UV ink, and is cured to form a UV film after being irradiated by ultraviolet light emitted from the second curing lamp 81.

Further, referring to fig. 5 and 6, the driving mechanism 20 is further configured to drive the loading mechanism 30 to pass through the curing station a8 located downstream of the spraying stations (i.e. downstream of the first spraying station a3 and the second spraying station a 4). The spraying apparatus further includes a third curing lamp 83 and a fourth curing lamp 82 arranged corresponding to the curing station a8. The third curing lamp 83 and the fourth curing lamp 82 are used for forming protective layers on the end face and the peripheral side outer wall of the battery a which are irradiated through the way, respectively. The protective layer on the end face of the battery a is gradually cured under the irradiation of ultraviolet light emitted from the third curing lamp 83, and the protective layer on the peripheral side outer wall of the battery a is gradually cured under the irradiation of ultraviolet light emitted from the fourth curing lamp 82.

It should be noted that, at the first spraying station a3, the first curing lamp 80 cures the protective layer on the peripheral outer wall of the battery a for the first time, so as to reduce the fluidity of the protective layer on the peripheral outer wall of the battery a, and avoid the material of the protective layer flowing along the surface of the battery a during the process of transferring the battery a downstream. At the curing station a8, the fourth curing lamp 82 performs a second curing of the protective layer on the peripheral outer wall of the battery a, ensuring that the protective layer on the peripheral outer wall of the battery a is completely cured.

Similarly, at the second spraying station a4, the second curing lamp 81 cures the protective layer on the end face of the battery a for the first time, so as to reduce the fluidity of the protective layer on the end face of the battery a and prevent the material of the protective layer from flowing along the surface of the battery a during the process of transferring the battery a downstream. At the curing station a8, the third curing lamp 83 performs a second curing of the protective layer on the end face of the battery a, so as to ensure that the protective layer on the end face of the battery a is thoroughly cured.

It should be noted that, if the curing station a8 is provided and the third curing lamp 83 and the fourth curing lamp 82 are disposed at the curing station a8, the first curing lamp 80 and the second curing lamp 81 are not necessary. In some embodiments, the first curing lamp 80 and the second fixing or the like 81 may not be provided, and the protective layer on the end surface and the peripheral outer wall of the battery a is cured only once at the curing station a 8.

Similarly, if the first curing lamp 80 and the second curing lamp 81 are provided at the first spraying station a3 and the second spraying station a4, respectively, the curing station a8 and the third curing lamp 83 and the fourth curing lamp 82 are not necessary. In other embodiments, the third curing lamp 83 and the fourth curing lamp 82 may not be provided, and the protective layer on the end face of the battery a is cured only once at the first spraying station a3, and the protective layer on the peripheral outer wall of the battery a is cured only once at the second spraying station a 4.

It should also be noted that the number of spraying stations is not limited to two. In other embodiments, only one spraying station may be provided, and the spraying mechanism 50 includes a first spraying assembly 51 and a second spraying assembly 52 disposed corresponding to the same spraying station. When the loading mechanism 30 reaches the spraying station, the loading mechanism 30 drives the battery a to rotate around the axis of the loading mechanism, the first spraying component 51 sprays one of the end face and the peripheral side outer wall of the battery a and forms a protective layer, and the second spraying component 52 sprays the other of the end face and the peripheral side outer wall of the battery a and forms a protective layer. That is, the first spray assembly 51 and the second spray assembly 52 spray-coat the end face and the peripheral side outer wall of the battery a at the same spray station simultaneously or at different times to form a protective layer on both the end face and the peripheral side outer wall of the battery a.

When the number of the spraying stations is one, the first curing lamps 80 and the second curing lamps 81 may be disposed corresponding to the spraying stations, and the protective layers on the end face and the peripheral side outer wall of the battery a may be irradiated with the first curing lamps 80 and the second curing lamps 81, respectively, to cure the protective layers on the end face and the peripheral side outer wall of the battery a. Of course, the first spray assembly 51 and the second spray assembly 52 are disposed at the same spray station, and there may be insufficient space for installing the first curing lamp 80 and the second curing lamp 81 due to limited space. Thus, in other embodiments, the first curing light 80 and the second curing light 81 may also be mounted at other stations downstream of the spraying station. For example, referring to fig. 4, the first curing lamps 80 and the second curing lamps 81 and the first detecting unit 61 described below are each arranged corresponding to the first detecting station a5 described below. That is, the first curing lamp 80 and the second curing lamp 81 are used to cure the protective layer on the end face and the peripheral outer wall of the battery a in addition to the detection of the protective layer on the battery a at the first detection station a 5. For ease of understanding, the following description will be given by taking the spray station arrangement as two examples.

Referring back to fig. 1, in particular embodiments, the drive mechanism 20 is further configured to drive the loading mechanism 30 through the cleaning station a2 upstream of the first spraying station a 3. The spraying apparatus further comprises a cleaning mechanism 40 arranged corresponding to the cleaning station a2, and the cleaning mechanism 40 is used for cleaning the battery a on the loading mechanism 30 reaching the cleaning station a2 so as to remove stains on the surface of the battery a, which is beneficial to improving the subsequent spraying quality. Alternatively, the cleaning mechanism 40 may employ a plasma cleaning mechanism.

It should be noted that, at the cleaning station a2, the loading mechanism 30 is required to drive the battery a to rotate, so as to ensure that the cleaning mechanism 40 performs 360 ° comprehensive cleaning on the battery a, and avoid the occurrence of a phenomenon that part of the battery a is not cleaned.

It should also be noted that in other embodiments, the cleaning station a2 and the cleaning mechanism 40 are not necessary in the case where the battery a has already undergone a cleaning process before being fed onto the device mechanism 30. Referring to fig. 5, the spray coating apparatus is not provided with the cleaning station a2 and the cleaning mechanism 40.

With continued reference to fig. 1, in particular embodiments, the drive mechanism 20 is further configured to drive the loading mechanism 30 through a first inspection station a5 downstream of the second spraying station a 4. The spraying apparatus further comprises a first inspection assembly 61 arranged in correspondence with the first inspection station. The first detecting assembly 61 is used for detecting the protection layer on the battery a on the loading mechanism 30 reaching the first detecting station a5 to determine whether the protection layer on the battery a is qualified.

Further, the driving mechanism 20 is further configured to drive the loading mechanism 30 to pass through the second detection station a6 located downstream of the first detection station a 5. The spraying device further comprises a second inspection assembly 62 arranged in correspondence with the second inspection station a6. When the driving mechanism 20 drives the loading mechanism 30 to move to the first detection station a5, the first detection assembly 61 detects the protective layer on the peripheral outer wall of the battery a. When the driving mechanism 20 drives the loading mechanism 30 to move to the second detection station a6, the second detection assembly 62 detects the protection layer on the end face of the battery a.

Of course, in other embodiments, when the driving mechanism 20 drives the loading mechanism 30 to move to the first detection station a5, the first detection assembly 61 detects the protection layer on the end face of the battery a. When the driving mechanism 20 drives the loading mechanism 30 to move to the second detection station a6, the second detection assembly 62 detects the protection layer on the peripheral outer wall of the battery a.

Alternatively, the first detecting assembly 61 may include an industrial camera (i.e., a CCD) with which an image of a corresponding protective layer is acquired and whether the protective layer is qualified is determined based on the acquired image.

The second detection assembly 62 may include an industrial camera (i.e., a CCD) that is utilized to image the corresponding protective layer and determine whether the protective layer is acceptable based on the acquired image.

It should be noted that, at the first detection station a5, the loading mechanism 30 is required to drive the battery a to rotate, so as to ensure that the first detection assembly 61 performs 360 ° comprehensive detection on the protective layer on the outer wall of the periphery side of the battery a, so as to avoid the occurrence of a situation that the protective layer is not detected locally. Similarly, at the second detection station a6, the loading mechanism 30 needs to be used to drive the battery a to rotate, so as to ensure that the second detection assembly 62 performs 360 ° comprehensive detection on the protection layer on the end face of the battery a, and avoid the situation that local part is not detected.

In particular, in the illustrated embodiment, the driving mechanism 20 is further configured to drive the loading mechanism 30 to pass through the loading station a1 located upstream of the cleaning station a 2. The spraying device further comprises a feeding turntable 10 arranged corresponding to the feeding station a1. When the driving mechanism 20 drives the loading mechanism 30 to move to the loading station a1, the loading turntable 10 rotates and drives the battery a to load onto the loading mechanism 30. It should be noted that the loading of the battery a is not limited to the loading of the battery a by the loading turntable 10. In other embodiments, a manner of mechanical arm feeding or manual feeding may be adopted, so long as the feeding of the battery a can be achieved, and the method is not limited herein.

In particular, in the embodiment, the driving mechanism 20 is further configured to drive the loading mechanism 30 to pass through the blanking station a7 located downstream of the second detecting station a 6. The spraying apparatus further comprises a blanking turntable 70 arranged in correspondence of the blanking station a7. When the driving mechanism 20 drives the loading mechanism 30 to move to the discharging station a7, the discharging turntable 70 rotates and drives the battery a on the loading mechanism 30 to discharge. In other embodiments, a manner of mechanical hand blanking or manual blanking may be adopted, as long as the blanking of the battery a can be achieved, and the method is not limited herein.

It should be noted that, referring to fig. 5, in other embodiments, the second detecting station a6 may not be provided, and the second detecting assembly 62 may be disposed corresponding to the blanking station a 7. After the blanking turntable 70 performs blanking on the battery a on the loading mechanism 30 passing through the blanking station a7, the second detection assembly 62 is used for detecting the protection layer on the end face of the battery a on the blanking turntable 70. Optionally, the second detection assembly 62 is mounted on the blanking carousel 70.

Referring to fig. 7 and 8, in the embodiment of the application, the loading mechanism 30 includes a mounting seat 31, and a bearing seat 32, a jacking assembly 33 and a back wheel assembly 34 all disposed on the mounting seat 31. The mounting block 31 is mounted on the drive mechanism 20 for routing through the various stations described above under the drive of the drive mechanism 20. The bearing seat 32 is located between the jacking assembly 33 and the back wheel assembly 34, and the bearing seat 32 is used for bearing the battery A. The lifting assembly 33 can be controlled to move towards the bearing seat 32, so as to lift the battery A on the bearing seat 32 to the back wheel assembly 34 and drive the battery A to rotate around the axis of the battery A. The back wheel assembly 34 is for abutting against the battery a lifted by the lift assembly 33 and allowing the battery a to rotate about its own axis.

In this way, when the driving mechanism 20 drives the mounting seat 31 to reach the first spraying station a3, the lifting assembly 33 approaches toward the bearing seat 32 to lift the battery a on the bearing seat 32 until the battery a is lifted onto the back wheel assembly 34. At this time, the battery a abuts against the back wheel assembly 34, so that the back wheel assembly 34 positions the battery a, and the jacking assembly 33 is prevented from generating a position offset when driving the battery a to rotate around its own axis. When the jacking component 33 drives the battery A to rotate around the axis of the battery A, the first spraying component 51 sprays the end face of the battery A and forms a protective layer.

After the spraying of the end part of the battery a is completed, the jacking component 33 stops driving the battery a to rotate, and the driving mechanism 20 drives the mounting seat 31 to move to the second spraying station a4. At the second spraying station a4, the jacking component 33 continuously drives the battery a to rotate around the axis of the jacking component, and the second spraying component 52 sprays the peripheral outer wall of the battery a and forms a protective layer.

In the embodiment, the back wheel assembly 34 includes a fixed seat 341, a back wheel 342, and a first magnetic attraction member (not shown). The fixed base 341 is mounted on the mounting base 31, and the back wheel 342 is rotatably connected to the fixed base 341 about its own axis. The first magnetic attraction piece is arranged on the fixed seat 341 to adsorb the battery A lifted by the lifting assembly 33 on the back wheel 342, so that the back wheel 342 is utilized to position the battery A, and position deviation and even falling in the lifting and rotating process are avoided. Alternatively, the first magnetic attraction member may employ a magnet.

Alternatively, the number of back wheels 342 may be two, with two back wheels 342 arranged side by side. The first magnetic attraction piece is used for adsorbing the battery A on the two back wheels 342, so that the battery A can be more stably and reliably abutted against the two back wheels 342, and the battery A can be positioned more accurately and reliably.

It should be noted that, in order to ensure that the battery a does not shift during rotation, in some embodiments, a pinch roller is mounted on the mount 31, and the pinch roller is disposed opposite to the back wheel 342. When the jacking assembly 33 jacks the battery a between the back wheel 342 and the pressing wheel, the pressing wheel moves close to the back wheel 342 to press the battery a on the back wheel 342, so that the battery a is prevented from deflecting. Because the pinch roller and the back wheel 342 are both rotatable about their axes, the jacking assembly 33 is able to rotate the battery a between the pinch roller and the back wheel 342. Alternatively, a translational drive may be used to drive the puck toward or away from the back wheel 342. Of course, in other embodiments, the driving of the puck can be accomplished in other ways, and is not limited in this regard.

In particular, in the embodiment, the jacking assembly 33 includes a jacking seat 331, a jacking rod 332, and a rotation driver 333. The jack 331 is disposed on the mounting base 31 and can be controllably moved toward and away from the carrier 32. The lifting rod 332 is rotatably connected to the lifting seat 331, so as to lift the battery a on the carrying seat 32 under the driving of the lifting seat 331. The rotation driving member 333 is mounted on the lifting base 331 and is in driving connection with the lifting rod 332 to drive the lifting rod 332 to rotate, thereby driving the battery a to rotate around its own axis. In this way, when the battery a needs to be lifted, the lifting seat 331 is controlled to move towards the bearing seat 32, so as to drive the lifting rod 332 to lift the battery a on the bearing seat 32 until the battery a is lifted onto the back wheel 342, and at this time, the battery a is adsorbed on the back wheel 342 by the first magnetic attraction member. When the battery a is lifted up by the lifting rod 332, the rotation driving member 333 drives the lifting rod 332 to rotate, thereby driving the battery a on the lifting rod 332 to rotate together. Alternatively, the rotary driver 333 may employ a motor.

Further, a second magnetic attraction member is disposed at an end of the lifting rod 332 facing the carrying seat 32, for attracting the battery a to the lifting rod 332. Thus, when the lifting rod 332 lifts the battery a, the battery a is attracted to the lifting rod 332 by the second magnetic attraction piece, so that the battery a is prevented from being shifted or even falling. And, because the battery a is attracted to the lifting rod 332 by the second magnetic attraction member, the lifting rod 332 can drive the battery a to rotate together. Alternatively, the second magnetic attraction member may employ a magnet.

Referring again to fig. 1, in an embodiment of the present application, the driving mechanism 20 includes a turntable assembly 21. The turntable assembly 21 is rotatably disposed about an axis of rotation. The mounting seat 31 is mounted on the turntable assembly 21 to rotate along with the turntable assembly 21 and sequentially passes through the feeding station a1, the cleaning station a2, the first spraying station a3, the second spraying station a4, the first detecting station a5, the second detecting station a6 and the discharging station a7. In order to protect the battery a during the battery a transferring process, the battery a may be loaded in a support cup B (see fig. 2), and the support cup B and the battery a loaded on the support cup B may be transferred as a whole at each station.

In this way, at the loading station a1, the cup B loaded with the battery a is loaded onto the carrier 32 by the loading turntable 10. At the cleaning station a2, the battery a on the carrier 32 is cleaned by the cleaning mechanism 40. Before reaching the first spraying station a3, the lifting rod 332 lifts the battery a on the carrier 32 to the back wheel assembly 34 (the supporting cup B remains carried on the carrier 32) so that the battery a abuts against the back wheel 342 under the suction effect of the first magnetic attraction member. At the first spraying station a3, the lifting rod 332 drives the battery a to rotate, and the first spraying assembly 51 is used for spraying on the end face of the battery a and forming a protective layer. At the second spraying station a4, the lifting rod 332 drives the battery a to rotate, and the second spraying assembly 52 is used for spraying on the peripheral outer wall of the battery a and forming a protective layer. At the first inspection station a5, the protective layer on the end face of the battery a is inspected by the first inspection assembly 61. At the second inspection station a6, the protective layer on the peripheral side outer wall of the battery a is inspected by the second inspection assembly 62. Before reaching the blanking station a7, the lifting rod 332 drives the battery a to descend until the battery a returns to the supporting cup B again, and the lifting rod 332 is separated from the battery a. At the blanking station a7, the blanking turntable 70 is used to blanking the cup B (in which case the battery a is loaded) on the carrier 32.

Further, the drive mechanism 20 also includes a guide assembly 22, the guide assembly 22 having a guide channel (not shown) extending about the axis of rotation. The jack 331 of the jack assembly 33 is rotatably connected with a guide roller 334, and the guide roller 334 is in rolling fit with the guide channel. When the turntable assembly 21 drives the mounting seat 31 to rotate around the rotation axis, the guide roller 334 rolls along the guide channel, so that the guide roller 334 can drive the lifting seat 331 of the lifting assembly 33 to move close to or away from the bearing seat 32 under the guiding action of the guide channel, so as to drive the lifting rod 332 to lift the battery a on the bearing seat 32. In this way, the rolling fit of the guide roller 334 and the guide channel is utilized to convert the rotary motion of the loading mechanism 30 into the linear motion of the jacking seat 331 close to or far from the bearing seat 32, and the linear driving piece module is not required to be additionally arranged for driving, so that the equipment cost is reduced.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
