Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically to a battery cell clamping device and a battery cell spraying equipment. Background Technology

[0002] In related technologies, during the process of applying or printing insulating coatings to battery cells using a battery cell clamping device, the insulating coating can easily be sprayed or printed onto the surface of the clamping device, thus contaminating it. Removing the insulating coating from the battery cell clamping device involves manual disassembly and cleaning or using external cleaning equipment. Both of these methods result in prolonged downtime for the battery cell insulation spraying or printing equipment, thereby affecting production continuity. Utility Model Content

[0003] The present invention provides a battery cell clamping device and a battery cell spraying equipment, which can improve the technical problem that it is difficult to automatically remove contaminants on the battery cell clamping device.

[0004] In a first aspect, embodiments of the present invention provide a battery cell clamping device, comprising:

[0005] The clamping member has a clamping groove for clamping the battery cell, and the clamping member has a flow channel through the surface of the clamping member for the discharge of contaminants;

[0006] A negative pressure collection mechanism is connected to the clamping member and communicates with the flow channel so that, under the negative pressure drive of the negative pressure collection mechanism, the contaminants on the clamping member enter the negative pressure collection mechanism through the flow channel.

[0007] By connecting the negative pressure collection mechanism to the clamping component and communicating with its flow channel, the negative pressure generated by the collection mechanism drives contaminants to flow within the flow channel and into the collection mechanism for collection. This achieves automatic cleaning of contaminants on the outer surface of the clamping component of the battery cell clamping device. It is understandable that applying negative pressure to the collection mechanism enables automatic cleaning of contaminants on the surface of the clamping component, thereby reducing the impact on the production continuity of the battery cell coating process.

[0008] In one embodiment, the negative pressure collection mechanism includes: a negative pressure member having a negative pressure chamber connected to the flow channel to drive the pollutants to flow within the flow channel; and a collection member having a collection trough connected to the flow channel to collect the pollutants.

[0009] By configuring the negative pressure collection mechanism as a negative pressure component and a collection component, the negative pressure component and the collection component can be connected to the clamping component respectively. Specifically, the negative pressure chamber of the negative pressure component is connected to the flow channel to drive the contaminants to flow within the flow channel, and the collection groove of the collection component is connected to the flow channel to collect the contaminants, thereby achieving automatic cleaning of contaminants on the surface of the clamping component.

[0010] In one embodiment, the clamping member includes a main body and two clamping arms connected to one end of the main body, a clamping groove is formed between the two clamping arms, the inlet of the flow channel is disposed on the top wall of the clamping arm, and the outlet of the flow channel is disposed on the bottom of the main body.

[0011] Understandably, since the battery cell is clamped between two clamping arms, a significant amount of contaminants will form on the top walls of the clamping arms during the process of applying or printing the insulating coating. By providing inlets for flow channels on the top walls of the clamping arms, the contaminants on the top walls of the clamping arms can directly enter the flow channels through the inlets. Furthermore, by placing the outlet of the flow channels at the bottom of the main body, the contaminants inside the flow channels can flow to the collection component through the outlet.

[0012] In one embodiment, the flow channel includes a first flow channel and a second flow channel, and the two clamping arms include a first clamping arm and a second clamping arm. The first flow channel passes through the first clamping arm and the main body, and the second flow channel passes through the second clamping arm and the main body.

[0013] By configuring the first flow channel to penetrate the first clamping arm and the main body, and configuring the second flow channel to penetrate the second clamping arm and the main body, contaminants formed on the surface of the first clamping arm can be discharged through the first flow channel, and contaminants formed on the surface of the second clamping arm can be discharged through the second flow channel, thereby improving cleaning efficiency.

[0014] In one embodiment, the collecting member is connected to the bottom of the main body along the height direction of the cell clamping device, and / or, at least a portion of the first flow channel and / or the second flow channel extends along the height direction of the cell clamping device.

[0015] By setting the first and second flow channels to extend along the height direction of the cell clamping device, the pollutants in the first and second flow channels are allowed to flow rapidly inside the first and second flow channels under the action of gravity. The collection component is connected to the bottom of the main body of the clamping component along the height direction of the cell clamping device, so that the pollutants flowing out of the outlet of the first and second flow channels can flow rapidly into the collection component under the action of gravity, thereby improving the cleaning efficiency.

[0016] In one embodiment, at least a portion of the top wall of the clamping arm is configured as an inclined surface sloping toward the interior of the flow channel.

[0017] By setting the top wall of the clamping arm to be inclined toward the inside of the flow channel, the contaminants formed on the top wall of the clamping arm are subjected to gravity on the inclined surface and thus flow into the inside of the flow channel.

[0018] In one embodiment, the main body is provided with an installation cavity, the negative pressure component is installed in the installation cavity, and both ends of the negative pressure cavity are provided with openings, which are respectively connected to the first flow channel and the second flow channel.

[0019] By connecting the openings at both ends of the negative pressure chamber to the first flow channel and the second flow channel respectively, the negative pressure inside the negative pressure chamber can be supplied to the first flow channel and the second flow channel through the openings at both ends of the negative pressure chamber.

[0020] In one embodiment, the collector is provided with a collection hole that connects to a collection tank and a negative pressure pipe to discharge contaminants.

[0021] By setting a collection hole connected to a negative pressure pipe inside the collection component, pollutants inside the collection tank can be quickly discharged under negative pressure, reducing the accumulation of pollutants inside the collection tank and improving cleaning efficiency.

[0022] In one embodiment, at least a portion of the bottom wall of the collection tank is configured as an inclined surface sloping toward the interior of the collection hole.

[0023] By setting at least a portion of the bottom wall of the collection tank as an inclined surface sloping toward the interior of the collection tank, contaminants attached to the top wall of the collection piece are facilitated to flow into the interior of the collection tank under the influence of gravity of the inclined surface.

[0024] In one embodiment, the top wall of the collecting component is provided with a plurality of collecting holes, some of which are close to one side of the bottom wall of the collecting tank and connected to the first flow channel, and other parts of which are close to the other side of the bottom wall of the collecting tank and connected to the second flow channel.

[0025] By setting multiple collection holes on one side of the bottom wall near the collection tank to vertically connect the first flow channel and the collection tank along the height direction of the cell clamping device, and by setting multiple collection holes on the other side of the bottom wall near the collection tank to vertically connect the second flow channel and the collection tank along the height direction of the cell clamping device, the flow rate of pollutants is increased.

[0026] In one embodiment, the cross-section of the top wall of the collector is configured as V-shaped.

[0027] By setting the cross-section of the top wall of the collector to a V-shape, the top wall of the collector is configured with a structure that is high in the middle and low on both sides, which facilitates the rapid flow of pollutants from the first and second flow channels into the collection tank.

[0028] In one embodiment, the surface energy of the clamping member is less than or equal to 30 mN / m; and / or, the surface energy of the negative pressure member is less than or equal to 30 mN / m; and / or, the surface energy of the collecting member is less than or equal to 30 mN / m.

[0029] By ensuring that the surface energy of the clamping component is less than or equal to 30 mN / m; and / or, the surface energy of the negative pressure component is less than or equal to 30 mN / m; and / or, the surface energy of the collecting component is less than or equal to 30 mN / m, the surface energy of the clamping component, the negative pressure component, and the collecting component is kept low, thereby reducing the adhesion of contaminants on the surfaces of the clamping component, the negative pressure component, and the collecting component, and thus promoting the flow of contaminants into the interior of the flow channel and the collecting tank.

[0030] Secondly, embodiments of this utility model provide a battery cell spraying device, which includes the battery cell clamping device described above.

[0031] The beneficial effects of the embodiments of this utility model are as follows:

[0032] In embodiments of this invention, by connecting the negative pressure chamber of the negative pressure component to the flow channel of the clamping component, the negative pressure generated by the negative pressure chamber of the negative pressure component can drive contaminants to flow within the flow channel of the clamping component and into the collection groove of the collecting component. The collecting component collects the contaminants, thereby achieving automatic cleaning of contaminants on the outer surface of the clamping component of the battery cell clamping device. It is understood that by introducing negative pressure into the negative pressure chamber of the negative pressure component, automatic cleaning of contaminants on the surface of the clamping component can be achieved, thereby reducing the impact on the production continuity of the battery cell coating process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0046] Embodiments of this application provide a battery cell coating apparatus, which includes a sprayer and a battery cell clamping device. The battery cell clamping device is adapted to clamp a battery cell, which can be a prismatic battery cell or a cylindrical battery cell. The sprayer is adapted to spray or print on the outer surface of the battery cell to form an insulating coating.

[0047] In related technologies, during the process of applying or printing insulating coatings to battery cells using a battery cell clamping device, the insulating coating can easily be sprayed or printed onto the surface of the clamping device, forming contaminants and thus contaminating the device. Removing the insulating coating from the battery cell clamping device involves manual disassembly and cleaning or using external cleaning equipment. Both methods result in prolonged downtime for the battery cell insulation spraying or printing equipment, affecting production continuity. Furthermore, manual disassembly and cleaning carries the risk of incomplete cleaning, while external cleaning equipment occupies space and increases the complexity of the battery cell insulation spraying or printing equipment.

[0048] This application provides a battery cell clamping device 100, such as Figures 1 to 3 As shown, the battery cell clamping device 100 includes a clamping member 1 and a negative pressure collection mechanism 20. The clamping member 1 forms a clamping groove 17 to clamp the battery cell 4. The clamping member 1 is provided with a flow channel 11 that penetrates the surface of the clamping member 1 to allow pollutants to be discharged. The negative pressure collection mechanism 20 is connected to the clamping member 1 and communicates with the flow channel 11 so that under the negative pressure drive of the negative pressure collection mechanism 20, the pollutants on the clamping member 1 enter the negative pressure collection mechanism 20 through the flow channel 11.

[0049] In the battery cell clamping device 100 provided in this application, by connecting the negative pressure collection mechanism 20 to the clamping member 1 and communicating with the flow channel 11 of the clamping member 1, the negative pressure generated by the negative pressure collection mechanism 20 can drive contaminants to flow within the flow channel 11 of the clamping member 1 and enter the negative pressure collection mechanism 20 for collection, thereby achieving automatic cleaning of contaminants on the outer surface of the clamping member 1 of the battery cell clamping device. It is understood that by applying negative pressure to the negative pressure collection mechanism 20, automatic cleaning of contaminants on the surface of the clamping member 1 can be achieved, thereby reducing the impact on the production continuity of the battery cell coating process. Compared with manual cleaning, the battery cell clamping device 100 provided in this application has an automatic cleaning function and high cleaning efficiency.

[0050] In some embodiments, the negative pressure collection mechanism 20 includes a separate negative pressure component 2 and a collection component 3. The negative pressure component 2 is provided with a negative pressure chamber 21, which is connected to a flow channel 11 to drive pollutants to flow in the flow channel 11. The collection component 3 is provided with a collection groove 31 and is connected to the flow channel 11 of the clamping component 1 to collect pollutants.

[0051] By configuring the negative pressure collection mechanism 20 as a negative pressure component 2 and a collection component 3, the negative pressure component 2 and the collection component 3 can be connected to the clamping component 1 respectively. By connecting the negative pressure chamber 21 of the negative pressure component 2 to the flow channel 11 of the clamping component 1, the negative pressure generated by the negative pressure chamber 21 of the negative pressure component 2 can drive contaminants to flow in the flow channel of the clamping component 1 and flow to the collection component 3. The collection groove 31 of the collection component 3 is connected to the flow channel 11 to collect the contaminants, thereby realizing the automatic cleaning of contaminants on the outer surface of the clamping component 1 of the battery cell clamping device 100. It can be understood that when negative pressure is introduced into the negative pressure chamber 21 of the negative pressure component 2, the contaminants on the surface of the clamping component 1 can be automatically cleaned, thereby reducing the impact on the production continuity of the battery cell spraying process.

[0052] In some embodiments, such as Figure 2 and Figure 3 As shown, the clamping member 1 includes a main body 12 and clamping arms 13. The clamping arms 13 are connected to one end of the main body 12. There are two clamping arms 13, and a clamping groove 17 is formed between the two clamping arms 13. The battery cell 4 is received in the clamping groove 17 and clamped by the two clamping arms 13. The inlet 111 of the flow channel 11 is provided on the top wall 14 of the clamping arm 13, and the outlet 112 of the flow channel 11 is provided on the bottom 15 of the main body 12.

[0053] Understandably, since the battery cell 4 is clamped between the two clamping arms 13, a significant amount of contaminants will form on the top walls 14 of the two clamping arms 13 during the process of spraying or printing the insulating coating on the battery cell 4. By providing an inlet 111 of the flow channel 11 on the top walls 14 of the two clamping arms 13, the contaminants on the top walls 14 of the clamping arms 13 can directly enter the interior of the flow channel 11 through the inlet 111. Furthermore, by providing the outlet 112 of the flow channel 11 at the bottom of the main body 12, it is convenient for the contaminants inside the flow channel 11 to flow to the collection member 3 through the outlet 112.

[0054] In some embodiments, such as Figures 2 to 4 As shown, the flow channel 11 includes a first flow channel 113 and a second flow channel 114, and the two clamping arms 13 include a first clamping arm 131 and a second clamping arm 132. The first flow channel 113 passes through the first clamping arm 131 and the main body 12, and the second flow channel 114 passes through the second clamping arm 132 and the main body 12.

[0055] By configuring the first flow channel 113 to penetrate the first clamping arm 131 and the main body 12, and configuring the second flow channel 114 to penetrate the second clamping arm 132 and the main body 12, pollutants formed on the surface of the first clamping arm 131 can be discharged through the first flow channel 113, and pollutants formed on the surface of the second clamping arm 132 can be discharged through the second flow channel 114, thereby improving cleaning efficiency.

[0056] In some embodiments, such as Figures 1 to 3As shown, the collecting member 3 is connected to the bottom 15 of the main body 12 of the clamping member 1 along the height direction of the cell clamping device 100, and / or, at least a portion of the first flow channel 113 and / or the second flow channel 114 extends along the height direction of the cell clamping device 100. In a specific embodiment, both the first flow channel 113 and the second flow channel 114 are configured to extend along the height direction of the cell clamping device 100, wherein the height direction of the cell clamping device 100 is as follows: Figure 2 The z-direction is shown.

[0057] By setting the first flow channel 113 and the second flow channel 114 to extend along the height direction of the cell clamping device 100, the pollutants in the first flow channel 113 and the second flow channel 114 are rapidly flowed inside the first flow channel 113 and the second flow channel 114 under the action of gravity. The collection member 3 is connected to the bottom 15 of the main body 12 of the clamping member 1 along the height direction of the cell clamping device 100, so that the pollutants flowing out of the outlet 112 of the first flow channel 113 and the outlet 112 of the second flow channel 114 are rapidly flowed into the collection member 3 under the action of gravity, thereby improving the cleaning efficiency.

[0058] In some embodiments, such as Figure 3 and Figure 4 As shown, the top wall 14 of the clamping arm 13 is configured as an inclined surface sloping toward the interior of the flow channel 11. By configuring the top wall 14 of the clamping arm 13 to slope toward the interior of the flow channel 11, the contaminants formed on the top wall 14 of the clamping arm 13 are subjected to gravity on the inclined surface and thus flow toward the interior of the flow channel 11.

[0059] In some embodiments, the clamping arm 13 includes a top wall 14, a first side wall and a second side wall disposed opposite to each other, the first side wall being connected to the top wall 14 and defining a clamping groove 17, and a gap being formed between one side of the top wall 14 and the second side wall, the gap defining the inlet 111 of the flow channel 11. Alternatively, a plurality of through holes may be provided on the top wall 14 of the clamping arm 13 near the second side wall to form the inlet 111 of the flow channel 11.

[0060] In some embodiments, such as Figures 2 to 4 As shown, the main body 12 of the clamping member 1 is provided with a mounting cavity 16, and the negative pressure member 2 is installed in the mounting cavity 16. The opening of the mounting cavity 16 is located on the bottom 15 of the main body 12. The negative pressure cavity 21 has openings 22 at both ends, and the openings 22 at both ends of the negative pressure cavity 21 are respectively connected to the first flow channel 113 and the second flow channel 114.

[0061] By connecting the openings 22 at both ends of the negative pressure chamber 21 to the first flow channel 113 and the second flow channel 114 respectively, the negative pressure inside the negative pressure chamber 21 can be provided to the first flow channel 113 and the second flow channel 114 through the openings 22 at both ends of the negative pressure chamber 21. Moreover, the openings 22 of the negative pressure chamber 21 are closer to the outlet 112 of the flow channel 11 than the inlet 111 of the flow channel 11. Therefore, the pressure at the outlet 112 of the flow channel 11 is less than the pressure at the inlet 111, thereby driving the pollutants inside the first flow channel 113 and the second flow channel 114 to flow to the outlet 112.

[0062] In some embodiments, the negative pressure member 2 is connected to the bottom wall of the mounting cavity 16 of the clamping member 1, and the connection between the negative pressure member 2 and the bottom wall of the mounting cavity 16 of the clamping member 1 can be by bonding or by bolting.

[0063] In some embodiments, such as Figure 2 , Figure 3 and Figure 5 As shown, the collecting component 3 is provided with a collecting hole 33, which connects the collecting tank 31 and the negative pressure pipe to discharge pollutants.

[0064] By setting a collection hole 33 connected to a negative pressure pipe in the collection component 3, the pollutants inside the collection tank 31 are quickly discharged under the action of negative pressure, reducing the accumulation of pollutants inside the collection tank 31 and improving cleaning efficiency.

[0065] The top of the collector 3 is connected to the bottom 15 of the main body 12 of the clamping member 1, and the top of the collector 3 has an open collection groove 31. By connecting the top of the collector 3 to the bottom 15 of the main body 12 of the clamping member 1, pollutants flowing out of the outlet 112 of the flow channel 11 can directly enter the collection groove 31. In a specific embodiment, the bottom wall 32 of the collection groove 31 can be connected to the bottom 15 of the main body 12 of the clamping member 1 by bonding or by bolting.

[0066] In some embodiments, at least a portion of the bottom wall 32 of the collection tank 31 is configured as an inclined surface sloping toward the interior of the collection hole 33. By configuring at least a portion of the bottom wall 32 of the collection tank 31 as an inclined surface sloping toward the interior of the collection hole 33, contaminants inside the collection tank 31 are facilitated to flow into the interior of the collection hole 33 under the influence of gravity of the inclined surface.

[0067] In some embodiments, such as Figure 2 , Figure 3 and Figure 5 As shown, the bottom wall 32 of the collection tank 31 is provided with a plurality of collection holes 33. Some of the collection holes 33 are close to one side of the bottom wall 32 of the collection tank 31 and are connected to the first flow channel 113, while other collection holes 33 are close to the other side of the bottom wall 32 of the collection tank 31 and are connected to the second flow channel 114.

[0068] By providing multiple collection holes 33 on one side of the bottom wall 32 near the collection tank 31, the first flow channel 113, the collection tank 31, and a portion of the collection holes 33 can be vertically connected along the height direction of the cell clamping device 100. By providing multiple collection holes 33 on the other side of the bottom wall 32 near the collection tank 31, the second flow channel 114, the collection tank 31, and a portion of the collection holes 33 can be vertically connected along the height direction of the cell clamping device 100, thereby increasing the flow rate of pollutants.

[0069] In some embodiments, the cross-section of the bottom wall 32 of the collection tank 31 is set to V-shape, so that the bottom wall 32 of the collection tank 31 is configured with a structure that is high in the middle and low on both sides, so that the pollutants flowing out of the first flow channel 113 and the second flow channel 114 can quickly flow into the interior of the collection tank 31.

[0070] In some embodiments, the surface energy of the surface of the clamping member 1 is less than or equal to 30 mN / m; and / or, the surface energy of the surface of the negative pressure member 2 is less than or equal to 30 mN / m; and / or, the surface energy of the surface of the collecting member 3 is less than or equal to 30 mN / m, so that the surface energy of the surfaces of the clamping member 1, the negative pressure member 2, and the collecting member 3 is low, thereby reducing the adhesion of contaminants on the surfaces of the clamping member 1, the negative pressure member 2, and the collecting member 3, thereby promoting the flow of contaminants into the interior of the flow channel 11 and the collection tank 31.

[0071] In some embodiments, the surfaces of the clamping member 1 and / or the negative pressure member 2 and / or the collecting member 3 are provided with a low surface energy coating, the surfaces of the clamping member 1 and / or the negative pressure member 2 and / or the collecting member 3 are provided with a low surface energy film layer, or the surface preparation material of the clamping member 1 and / or the negative pressure member 2 and / or the collecting member 3 includes a low surface energy material, and the material suitable for preparing the low surface energy coating or the low surface energy material includes one or more of polytetrafluoroethylene, organosilicon / fluorosilicone rubber, and nanocomposite oleophobic and hydrophobic coating.
