Description

Technical Field

[0001] This utility model relates to the field of lithium battery equipment technology, and in particular to an anti-sticking roller structure. It also relates to a coating equipment equipped with the anti-sticking roller structure. Background Technology

[0002] Currently, in the coating process of lithium battery manufacturing, pre-prepared positive / negative electrode slurries (active materials) are typically coated / transferred uniformly onto current collectors (copper foil, aluminum foil) using a coating machine with a specific coating method. After staged drying, the positive / negative electrode sheets in the lithium-ion battery are formed. The quality of the coating has a significant impact on the quality of the electrode sheets. However, during the production process, temperature fluctuations or the formation of a thick coating layer during machine start-up and shutdown often occur, resulting in incomplete drying of the electrode sheets. This causes wet material to adhere to the pressure rollers in contact with the electrode sheets, continuously contaminating subsequent electrode sheets and adversely affecting their quality.

[0003] Although existing technologies have pressure roller structures that can dry the electrode sheet while rolling, thus solving the above problems, the drying effect of such pressure roller structures is poor, and the structure is fixed, making it difficult to maintain and replace. In addition, the applicable working conditions are also relatively limited, which is not conducive to meeting coating operations with different drying requirements. Utility Model Content

[0004] In view of this, the present invention aims to propose an anti-sticking roller structure, which is convenient for maintenance and also suitable for coating operations that meet different drying requirements.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] An anti-stick roller structure includes a first mounting rod assembly and a second mounting rod assembly arranged coaxially and spaced apart, a pressure roller assembly rotatably disposed between the first mounting rod assembly and the second mounting rod assembly, and a heat lamp assembly disposed between the first mounting rod assembly and the second mounting rod assembly.

[0007] The pressure roller assembly includes a pressure roller rotatably mounted on the first mounting rod assembly and the second mounting rod assembly at both ends, and a heating component located in the inner cavity of the pressure roller. The heating component is spaced apart from the inner wall of the pressure roller, and the heating component is mounted on the first mounting rod assembly by a fixing member.

[0008] The heat lamp assembly includes a mounting bracket, a lamp panel disposed on the mounting bracket, and a heat lamp disposed on the lamp panel, wherein the mounting bracket is detachably connected to both the first mounting rod assembly and the second mounting rod assembly.

[0009] Furthermore, the first mounting rod assembly includes a first mounting rod for mounting on an external device and a first connecting rod connected to the first mounting rod, with the fixing member passing through the first connecting rod and the first mounting rod; the second mounting rod assembly includes a second mounting rod for mounting on the external device and a second connecting rod connected to the second mounting rod; the two ends of the pressure roller are rotatably mounted on the first connecting rod and the second connecting rod, respectively, and a drive assembly connected to the pressure roller is provided in the inner cavity of the second connecting rod.

[0010] Furthermore, the mounting bracket includes a base plate, and a first support member and a second support member respectively disposed at both ends of the base plate; the first support member is detachably connected to a first connecting seat on the first connecting rod through a first connecting structure, and the second support member is detachably connected to a second connecting seat on the second connecting rod through a second connecting structure.

[0011] Furthermore, the first connection structure includes a first slot disposed on the first connector and a first insertion protrusion disposed on the first support member, the first insertion protrusion being inserted into the first slot; the second connection structure includes a second slot disposed on the second connector and a second insertion protrusion disposed on the second support member, the second insertion protrusion being inserted into the second slot.

[0012] Furthermore, the first connection structure includes a first locking hole on the first connector that communicates with the first slot, a first mating hole on the first insertion protrusion, and a first fastener screwed into the first locking hole and the first mating hole; and / or, the second connection structure includes a second locking hole on the second connector that communicates with the second slot, a second mating hole on the second insertion protrusion, and a second fastener screwed into the second locking hole and the second mating hole.

[0013] Furthermore, the first slot has a guide portion at its opening for guiding the insertion of the first plug-in protrusion; and / or, the second slot has a guide portion at its opening for guiding the insertion of the second plug-in protrusion.

[0014] Furthermore, the cross-section of the first insertion protrusion and / or the cross-section of the second insertion protrusion are T-shaped.

[0015] Furthermore, the first mounting rod is provided with an insertion hole, and the first connecting rod is provided with a through hole. The fixing member passes through the through hole and is inserted into the insertion hole.

[0016] Furthermore, there are multiple heating lamps mounted on a lamp panel, and each heating lamp and the lamp panel are connected by screws or snaps.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] The anti-stick roller structure described in this utility model, through the combined use of the baking lamp assembly and the heating component, can perform secondary drying on undried electrode sheets, preventing wet coating from sticking to the pressure roller and affecting the coating quality, thereby improving the yield of coated products. At the same time, the mounting bracket can be detachably connected to both the first mounting rod assembly and the second mounting rod assembly, which not only facilitates the maintenance and replacement of the baking lamp assembly, but also allows the baking lamp assembly to be disassembled when the drying demand is low, enabling drying operations to be performed solely by the heating component, or the heating component to be turned off, allowing drying operations to be performed solely by the baking lamp assembly. This makes it suitable for coating operations with different drying requirements, thus giving the anti-stick roller structure excellent performance.

[0019] Furthermore, the arrangement of the first and second connecting seats facilitates the assembly and disassembly of the mounting bracket from the first and second connecting rods. The engagement of the first insertion protrusion with the first slot, and the engagement of the second insertion protrusion with the second slot, simplifies operation and facilitates quick disassembly. The coordinated arrangement of the first locking hole, the first mating hole, and the first fastener not only facilitates quick disassembly but also reduces manufacturing costs.

[0020] In addition, a guide section is provided to facilitate the insertion operations between the first insertion protrusion and the first slot, and between the second insertion protrusion and the second slot. The cross-sections of the first and second insertion protrusions are T-shaped, which facilitates a limiting fit between the first insertion protrusion and the first slot, and between the second insertion protrusion and the second slot, in the direction perpendicular to the insertion direction, ensuring the stability of the baking lamp assembly. Each baking lamp and lamp panel is connected by screws or snaps, facilitating the maintenance and replacement of the baking lamps and the adjustment of the number of baking lamps to suit coating operations with different drying requirements.

[0021] Another objective of this invention is to provide a coating device, wherein the coating device is provided with the anti-sticking roller structure described above.

[0022] The coating equipment described in this utility model is equipped with the aforementioned anti-sticking roller structure, which has the same beneficial effects as traditional technology, and will not be described in detail here. Attached Figure Description

[0041] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] Example 1

[0043] This embodiment relates to an anti-sticking roller structure, which not only improves the drying effect on the electrode sheets, but also facilitates maintenance and is suitable for coating operations that meet different drying requirements.

[0044] In terms of overall structure, such as Figures 1 to 7 As shown, the anti-stick roller structure of this embodiment includes a first mounting rod 1 assembly and a second mounting rod 2 assembly arranged coaxially and at intervals, a pressure roller 5 assembly rotatably disposed between the first mounting rod 1 assembly and the second mounting rod 2 assembly, and a heat lamp 10 assembly disposed between the first mounting rod 1 assembly and the second mounting rod 2 assembly.

[0045] Furthermore, the pressure roller 5 assembly includes a pressure roller 5 rotatably mounted on the first mounting rod 1 assembly and the second mounting rod 2 assembly at both ends, and a heating element 6 located in the inner cavity of the pressure roller 5. The heating element 6 is spaced apart from the inner wall of the pressure roller 5, and the heating element 6 is mounted on the first mounting rod 1 assembly via a fixing member 7. The baking lamp 10 assembly includes a mounting bracket 8, a lamp plate 9 mounted on the mounting bracket 8, and a baking lamp 10 mounted on the lamp plate 9. The mounting bracket 8 is detachably connected to both the first mounting rod 1 assembly and the second mounting rod 2 assembly.

[0046] At this time, with the above settings, the undried electrode sheet can be dried a second time by using the baking lamp 10 assembly and the heating element 6 together, avoiding the wet coating from sticking to the pressure roller 5 and affecting the coating quality, so as to improve the yield of coated products. At the same time, the mounting bracket 8 can be detachably connected to both the first mounting rod 1 assembly and the second mounting rod 2 assembly, which not only facilitates the maintenance and replacement of the baking lamp 10 assembly, but also allows the baking lamp 10 assembly to be disassembled when the drying demand is small, and the drying operation can be carried out by the heating element 6 alone, or the drying operation can be carried out by the baking lamp 10 assembly alone after the heating element 6 is turned off. This makes it suitable for coating operations with different drying requirements, so that the anti-stick roller structure has a good performance.

[0047] Based on the above overall introduction, in detail, in this embodiment, the heating component 6 can preferably be a common heating tube or heating wire, and the heating component 6 can be connected to an external power supply device through a heating wire harness. At this time, a through hole for the heating wire harness to pass through can be provided on the first mounting rod 1 assembly.

[0048] In this embodiment, as a preferred implementation, such as Figure 1 As shown, the first mounting rod 1 assembly includes a first mounting rod 1 for mounting on an external device, and a first connecting rod 3 connected to the first mounting rod 1. A fixing member 7 passes through the first connecting rod 3 and the first mounting rod 1. Simultaneously, the second mounting rod 2 assembly includes a second mounting rod 2 for mounting on an external device, and a second connecting rod 4 connected to the second mounting rod 2. The two ends of the pressure roller 5 are rotatably mounted on the first connecting rod 3 and the second connecting rod 4, respectively, and a drive assembly 11, which is driven and connected to the pressure roller 5, is provided in the inner cavity of the second connecting rod 4.

[0049] Specifically, the aforementioned external equipment can be coating equipment, electrode slitting equipment, electrode die-cutting equipment, or electrode stacking equipment, etc. In this embodiment, the coating equipment is mainly used as an example for explanation. In this case, the anti-sticking roller structure can be installed on the frame of the coating equipment by means of technical means known to those skilled in the art. For example, the first mounting rod 1 can preferably be provided with a mounting hole for connecting with the frame, and the second mounting rod 2 can preferably be provided with a plug hole 21 for inserting into the plug on the frame, etc.

[0050] Meanwhile, in this embodiment, the through hole for the heating wire harness to pass through can preferably be provided on the first connecting rod 3. The drive assembly 11 can preferably include a drive motor 111 and a drive rod 112 connected to the drive end of the drive motor 111. The drive rod 112 is connected to the pressure roller 5. Of course, the drive motor 111 can be connected to an external power supply device through the motor wire hole provided on the second connecting rod 4.

[0051] Furthermore, the fixing member 7 in this embodiment can be rod-shaped. As a preferred embodiment, the first mounting rod 1 is provided with an insertion hole, and the first connecting rod 3 is provided with a through hole. The fixing member 7 passes through the through hole and is inserted into the insertion hole so as to be installed with the fixing member 7.

[0052] It should also be mentioned that the two ends of the pressure roller 5 can be rotatably connected to the first connecting rod 3 and the second connecting rod 4 respectively by means of technology known to those skilled in the art. For example, the two ends of the pressure roller 5 are respectively provided with rotating protrusions that protrude inward along their own radial direction, and the first connecting rod 3 and the second connecting rod 4 are both provided with rotating grooves. Each rotating protrusion rotates in the rotating groove on the same side. This will not be described in detail here.

[0053] Furthermore, in this embodiment, as a preferred implementation, the mounting bracket 8 includes a base plate 81, and a first support member 82 and a second support member 83 respectively disposed at both ends of the base plate 81. The first support member 82 is detachably connected to a first connecting seat 30 on the first connecting rod 3 via a first connecting structure, and the second support member 83 is detachably connected to a second connecting seat 40 on the second connecting rod 4 via a second connecting structure. The provision of the first connecting seat 30 and the second connecting seat 40 facilitates the assembly and disassembly of the mounting bracket 8 from the first connecting rod 3 and the second connecting rod 4.

[0054] In specific implementation, in this embodiment, as a preferred embodiment, such as... Figure 3 and Figure 5 As shown, the first connection structure includes a first slot 31 disposed on the first connecting seat 30 and a first insertion protrusion 821 disposed on the first support member 82, the first insertion protrusion 821 being inserted into the first slot 31. It can be understood that the insertion and engagement of the first insertion protrusion and the first slot 31 simplify the connection operation between the first support member 82 and the first connecting seat 30, facilitating quick disassembly.

[0055] Meanwhile, as a preferred embodiment, the second connection structure of this embodiment includes a second slot provided on the second connecting seat 40 and a second insertion protrusion provided on the second support member 83, the second insertion protrusion being inserted into the second slot. That is, the second connection structure can adopt the same structural design as the first connection structure to achieve the beneficial effect of simple connection operation and quick disassembly.

[0056] At this time, combined Figure 4 As shown, in a preferred embodiment, the first connection structure includes a first locking hole 312 on the first connecting seat 30 that communicates with the first slot 31, a first mating hole on the first insertion protrusion 821, and a first fastener 822 screwed into the first locking hole 312 and the first mating hole.

[0057] The combination of the first locking hole 312, the first mating hole, and the first fastener 822 facilitates quick disassembly and reduces manufacturing costs. In practice, the first fastener 822 can be a bolt, which is screwed into the first locking hole 312. Simultaneously, the bolt can be screwed into the first mating hole while simultaneously pressing the first insertion protrusion 821 into the first slot 31. If necessary, the aforementioned first connection structure can be arranged in two sets at intervals to improve the connection stability between the first support member 82 and the first connecting seat 30.

[0058] Meanwhile, as a preferred embodiment, the second connection structure of this embodiment can be similar to the first connection structure to achieve good connection stability. For example, the second connection structure includes a second locking hole on the second connecting seat 40 that communicates with the second slot, a second mating hole on the second insertion protrusion, and a second fastener screwed into the second locking hole and the second mating hole. Of course, based on the requirement of quick release, the second connection structure may only include the aforementioned second insertion protrusion and second slot, and because of the presence of the first connection structure, the second connection structure can also achieve good stability.

[0059] Furthermore, in this embodiment, as a preferred embodiment, the opening of the first slot 31 is provided with a guide portion 311 for guiding the insertion of the first insertion protrusion 821, so as to facilitate the insertion operation between the first insertion protrusion and the first slot 31. Similarly, as a preferred embodiment, the opening of the second slot is provided with a guide portion 311 for guiding the insertion of the second insertion protrusion, also to facilitate the insertion operation between the second insertion protrusion and the second slot.

[0060] In this embodiment, only Figure 3 and Figure 5 The guide portion 311 at the opening of the first slot 31 is shown in the figure, so as to Figure 5 Taking the illustrated state as an example, the guide portion 311 includes side guide slopes on the left and right sides of the first slot 31 and a bottom guide slope at the bottom of the first slot 31, so as to play a good guiding role when the first insertion protrusion is inserted into the first slot 31. In this embodiment, the guide portion 311 at the opening of the second slot can preferably adopt the same structural design as the guide portion 311 at the opening of the first slot 31, which will not be described in detail here.

[0061] In addition, in this embodiment, as a preferred implementation, it is still as follows Figure 4 As shown, the cross-section of the first insertion protrusion 821 and the cross-section of the second insertion protrusion are T-shaped, that is, the cross-sections of the first slot 31 and the second slot are also T-shaped.

[0062] In this way, a limiting fit can be formed between the first insertion protrusion and the first slot 31, and between the second insertion protrusion and the second slot in the vertical direction of the insertion direction, to ensure the connection stability between the first support member 82 and the first connecting seat 30 and the second support member 83 and the second connecting seat 40, thereby ensuring the stability of the use of the heat lamp 10 assembly.

[0063] Meanwhile, in this embodiment, as a preferred implementation, reference is continued. Figure 1 As shown, there are multiple baking lamps 10 mounted on the lamp plate 9, and each baking lamp 10 and the lamp plate 9 are connected by screws or clips. This facilitates the maintenance and replacement of the baking lamps 10, and the adjustment of the number of baking lamps 10 to suit coating operations with different drying requirements.

[0064] It is worth mentioning that, in the specific implementation of this embodiment, as follows: Figure 2 As shown, the first mounting rod 1 assembly, the pressure roller 5 assembly, and the second mounting rod 2 assembly can preferably be set as two sets. The first support member 82 and the second support member 83 in the mounting bracket 8 are also preferably set as two sets on the substrate 81. At this time, the two first support members 82 are detachably connected to the two first connecting rods 3 respectively, and the two second support members 83 are detachably connected to the two second connecting rods 4 respectively. The main advantage of this setting is that it can improve the installation stability of the baking lamp 10 assembly and the overall drying effect.

[0065] Of course, if necessary, this embodiment can also set the first mounting rod 1 assembly, the pressure roller 5 assembly and the second mounting rod 2 assembly as a group according to the drying requirements, and cooperate with a common roller to install the baking lamp 10 assembly with two sets of first support members 82 and second support members 83, thereby ensuring that the baking lamp 10 assembly has good installation stability.

[0066] In this embodiment, the heating lamp 10 can re-dry some of the un-dried coating as the electrode passes by. At this time, the heating element 6 does not directly contact the pressure roller 5, preventing the pressure roller 5 from overheating and causing the coating to stick to it. Furthermore, it can work in conjunction with the heating lamp 10 to bake the electrode, resulting in a better anti-sticking effect for the pressure roller 5. Moreover, any structural parts not mentioned in the anti-sticking roller structure of this embodiment can be referred to in anti-sticking roller products well-known to those skilled in the art, such as the structures disclosed in Chinese Utility Model Patent CN214132587U for lithium battery devices, and will not be elaborated upon here.

[0067] The anti-stick roller structure of this embodiment can prevent wet coating from sticking to the pressure roller 5 and affecting the coating quality, thereby improving the yield of coated products. At the same time, it is also suitable for coating operations with different drying requirements, thus having a good performance.

[0070] The coating equipment of this embodiment, by setting the anti-stick roller structure in Embodiment 1, is suitable for coating operations with different drying requirements and can have higher practicality.

[0071] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
