Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a coating and dispensing device, wet coating manufacturing equipment, dry coating manufacturing equipment, and a battery production system. Background Art

[0002] With the popularization and promotion of new energy vehicles, the charging and discharging performance, endurance, etc. of new energy vehicles are increasingly attracting people's attention and attention. Batteries, as the power energy of new energy vehicles, are widely used.

[0003] In existing electrode production processes, wet or dry coating methods typically apply insulating adhesive to the electrode edges to provide an additional layer of high-insulation material and prevent short circuits at the electrode edges. Existing adhesive coating equipment requires manual adjustment of coating parameters, which is time-consuming and labor-intensive. Furthermore, it is difficult to ensure consistency in coating thickness, width, and weight, impacting electrode quality and production efficiency. Summary of the Invention

[0004] Based on this, it is necessary to provide a coating dispensing device, wet coating manufacturing equipment, dry coating manufacturing equipment and battery production system to address the problem that the coating parameters in the existing coating device need to be manually adjusted and have poor consistency.

[0005] A coating and dispensing device includes a feeding mechanism, a diverter mechanism, a discharging mechanism, a coating mechanism and an online detection mechanism. The diverter mechanism includes at least two diverter pipes and a diverter adjustment component. The diverter adjustment component is arranged in the diverter pipe and is used to adjust the flow and / or pressure of the diverter pipe. The discharging mechanism includes at least two discharging pipes. The feeding mechanism is connected with the corresponding discharging pipes through each diverter pipe. The coating mechanism is connected with each discharging pipe and is used to apply glue to the target part. The online detection mechanism is electrically connected with the diverter adjustment component. The online detection mechanism is used to detect the gluing parameters of the target part and adjust the diverter adjustment component according to the gluing parameters of the target part to adjust the flow and / or pressure of the diverter pipe. The above-mentioned coating and dispensing device utilizes a feeding mechanism to supply glue, and the glue flows to each discharge pipe through each branch pipe, and then flows to the coating mechanism, and is coated with glue on the target part through the coating mechanism. After the target part is coated with glue, the online detection mechanism detects the coating parameters of the target part in real time, and adjusts the branch adjustment component according to the coating parameters of the target part to continuously adjust the flow and / or pressure of the branch pipe so that the coating parameters of the target part are within the expected range. Without manual intervention, online closed-loop adjustment of the glue discharge flow and / or glue discharge pressure can be achieved, which is beneficial to improving the coating consistency and uniformity of the target part.

[0006] In some embodiments, the flow diversion regulating assembly includes a flow diversion chamber and a first regulating member. The flow diversion chamber is disposed within and communicates with the flow diversion pipeline. The first regulating member is secured to the flow diversion chamber and is used to regulate the pressure in the flow diversion pipeline. Thus, during the dispensing process, the pressure in the flow diversion chamber is regulated by the first regulating member, thereby regulating the pressure in the flow diversion pipeline, thereby effectively controlling the flow rate and velocity of the rubber material. This provides convenient operation and a rational structural design.

[0007] In some embodiments, the first regulating member includes a valve body, a regulating portion, and a detecting portion. The detecting portion is fixed to the diversion cavity and is used to detect the pressure in the diversion pipeline. The valve body is connected to the diversion cavity and is used to regulate the pressure in the diversion pipeline. The regulating portion is located on the valve body and is used to adjust the valve body opening. In this way, by controlling the regulating portion to adjust the valve body opening, the space within the diversion cavity for the rubber material to pass through is adjusted to achieve online closed-loop adjustment of the dispensing pressure without manual intervention, which is convenient to operate and has a reasonable structural design.

[0008] In some embodiments, the flow diversion regulating assembly further includes a second regulating member that at least partially extends into the diversion cavity and is used to regulate the flow rate in the diversion conduit. Thus, during the dispensing process, the second regulating member regulates the flow rate in the diversion cavity, thereby regulating the flow rate in the diversion conduit, effectively controlling the flow rate and flow velocity of the adhesive, thereby providing convenient operation and a reasonable structural design.

[0009] In some embodiments, the second adjustment member includes a drive portion, a coupling portion, and a flow block. The flow block is connected to the drive portion via the coupling portion, and at least partially extends into the diversion cavity. Driven by the drive portion, the coupling portion drives the flow block to move, thereby adjusting the length of the flow block extending into the diversion cavity. Thus, by adjusting the length of the flow block extending into the diversion cavity, the space within the diversion cavity for the rubber material to pass through is adjusted, thereby regulating the flow rate of the diversion pipe. This allows for online closed-loop regulation of the rubber discharge flow rate without manual intervention, resulting in convenient operation and a reasonable structural design.

[0010] In some embodiments, the diversion cavity has a reflux port, and the diversion mechanism further includes a recovery pipe and a recovery filter. The recovery pipe connects the reflux port and the feed mechanism, and the recovery filter is disposed in the recovery pipe and is used to filter the rubber material in the recovery pipe. In this way, excess rubber material in the diversion pipe or diversion cavity can flow into the recovery pipe, be filtered by the recovery filter, and then flow to the feed mechanism, thereby achieving recycling and reuse of the rubber material and improving the reuse rate of resources.

[0011] In some embodiments, the discharging mechanism further includes a discharging adjustment member disposed within the discharging conduit and configured to adjust the flow rate within the discharging conduit. Thus, during the dispensing process, the discharging adjustment member directly adjusts the flow rate within the discharging conduit, effectively controlling the flow rate and velocity of the adhesive. This provides for convenient operation and a rationally designed structure.

[0012] In some embodiments, the online detection mechanism includes an electrically connected controller, a first detection member, a second detection member, and a third detection member. The first detection member is used to detect the gluing parameters of the target part. The second detection member is provided in the shunt pipe and is used to detect the flow rate of the shunt pipe. The third detection member is provided in the shunt pipe and is used to detect the pressure of the shunt pipe. The controller adjusts the flow rate and / or pressure of the shunt pipe according to the detection results of the first detection member, the second detection member, and the third detection member. In this way, during the dispensing process, the controller adjusts the flow rate and / or pressure of the shunt pipe according to the detection results of the first detection member, the second detection member, and the third detection member. Without manual intervention, online closed-loop adjustment of the glue discharge flow rate and / or glue discharge pressure can be achieved, which is beneficial to improving the consistency and uniformity of the glue coating on the target part.

[0013] In some embodiments, the feeding mechanism includes a storage assembly, a stirring assembly, and a drive assembly. The storage assembly is used to store the rubber material, and the stirring assembly is used to stir the rubber material in the storage assembly. The drive assembly is connected to the storage assembly and one end of each branch pipe, and is used to transport the rubber material in the storage assembly to each branch pipe. In this way, driven by the drive assembly, the rubber material in the storage assembly can be transported to each branch pipe. At the same time, the stirring assembly stirs the rubber material to eliminate bubbles in the rubber material and facilitate uniform transportation of the rubber material. This can achieve storage of the rubber material and rapid and smooth transportation, which is conducive to improving gluing efficiency.

[0014] A wet coating manufacturing device includes the aforementioned coating and dispensing device and a conveying device. The conveying device is located upstream of the coating and dispensing device and is used to transport a target part, which is a pole piece manufactured by wet coating. The aforementioned wet coating manufacturing device applies glue to the target part via a coating mechanism. After the target part is coated with glue, an online detection mechanism detects the coating parameters of the target part in real time and adjusts the shunt adjustment component based on the coating parameters of the target part to continuously adjust the flow rate and / or pressure of the shunt pipe so that the coating parameters of the target part meet the expected range. Without manual intervention, online closed-loop adjustment of the glue discharge flow rate and / or glue discharge pressure can be achieved, which is beneficial to improving the consistency and uniformity of the glue coating of the target part.

[0015] In some embodiments, the coating mechanism is a slit coating head, so that the adhesive can be evenly coated on the surface of the target part through the slit coating head, which is beneficial to improving the consistency and uniformity of the adhesive coating on the target part.

[0016] A dry coating manufacturing device includes the aforementioned coating and dispensing device and a conveying device. The conveying device is located upstream of the coating and dispensing device and is used to transport a target part, which is a pole piece manufactured by dry coating. The aforementioned dry coating manufacturing device applies glue to the target part via a coating mechanism. After the target part is coated with glue, an online detection mechanism detects the coating parameters of the target part in real time and adjusts the shunt adjustment component based on the coating parameters of the target part to continuously adjust the flow rate and / or pressure of the shunt pipe so that the coating parameters of the target part meet the expected range. Without manual intervention, online closed-loop adjustment of the glue output flow rate and / or glue output pressure can be achieved, which is beneficial to improving the consistency and uniformity of the glue coating of the target part.

[0017] In some embodiments, the coating mechanism includes a mounting base, a moving assembly, a rotating assembly, and a dispensing head. The dispensing head is used to apply glue to the target part. The rotating assembly is connected to the dispensing head and is used to drive the dispensing head to rotate. The moving assembly is mounted on the mounting base and is connected to the rotating assembly and is used to drive the dispensing head to move. In this way, the dispensing head can be moved by the moving assembly and rotated by the rotating assembly to adjust the position and angle of the dispensing head to a desired range, thereby improving the dispensing accuracy and efficiency of the dispensing head.

[0018] A battery production system includes the aforementioned coating and dispensing device, the aforementioned wet coating manufacturing equipment, or the aforementioned dry coating manufacturing equipment. In the aforementioned battery production system, the coating mechanism applies glue to the target part.

Without manual intervention, online closed-loop adjustment of the glue discharge flow rate and / or glue discharge pressure can be achieved, which helps improve the consistency and uniformity of the glue coating on the target part.

[0042] With the popularization and promotion of new energy vehicles, the charging and discharging performance, endurance, etc. of new energy vehicles are increasingly attracting people's attention and attention. Batteries, as the power energy of new energy vehicles, are widely used.

[0043] In existing electrode production processes, wet or dry coating methods typically apply insulating adhesive to the electrode edges to provide an additional layer of high-insulation material and prevent short circuits at the electrode edges. Existing adhesive coating equipment requires manual adjustment of coating parameters, which is time-consuming and labor-intensive. Furthermore, it is difficult to ensure consistency in coating thickness, width, and weight, impacting electrode quality and production efficiency.

[0044] Based on the above considerations and after in-depth research, this application has designed a coating and dispensing device, wet coating manufacturing equipment, dry coating manufacturing equipment and battery production system, which uses a feeding mechanism to supply glue, and the glue flows to each discharge pipe through each diversion pipe, and then flows to the coating mechanism, and is applied to the target part through the coating mechanism. After the target part is coated with glue, the online detection mechanism detects the coating parameters of the target part in real time, and adjusts the diversion adjustment component according to the coating parameters of the target part to continuously adjust the flow and / or pressure of the diversion pipe so that the coating parameters of the target part are within the expected range. Without manual intervention, online closed-loop adjustment of the glue discharge flow and / or glue discharge pressure can be achieved, which is beneficial to improving the glue coating consistency and uniformity of the target part.

[0045] Please refer to Figures 1 to 8In one embodiment, the coating and dispensing device 10 includes a feeding mechanism 100, a diverter mechanism 200, a discharging mechanism 300, a coating mechanism 400 and an online detection mechanism 500. The diverter mechanism 200 includes at least two diverter pipes 210 and a diverter adjustment component 220. The diverter adjustment component 220 is arranged in the diverter pipe 210 and is used to adjust the flow and / or pressure of the diverter pipe 210. The discharging mechanism 300 includes at least two discharging pipes 310. The feeding mechanism 100 is connected to the corresponding discharging pipes 310 through each diverter pipe 210. The coating mechanism 400 is connected to each discharging pipe 310 and is used to apply glue to the target part. The online detection mechanism 500 is electrically connected to the diverter adjustment component 220; wherein, the online detection mechanism 500 is used to detect the gluing parameters of the target part and adjust the diverter adjustment component 220 according to the gluing parameters of the target part to adjust the flow and / or pressure of the diverter pipe 210.

[0046] It should be noted that, during the dispensing process, the feeding mechanism 100 is used to supply the glue, and the glue flows to the discharge pipes 310 through the diversion pipes 210, and then flows to the coating mechanism 400, and the target part is coated with glue through the coating mechanism 400. After the target part is coated with glue, the online detection mechanism 500 detects the gluing parameters of the target part in real time, and adjusts the diversion adjustment component 220 according to the gluing parameters of the target part to continuously adjust the flow and / or pressure of the diversion pipe 210 until the gluing parameters of the target part reach the expected range, and stops adjusting the flow and / or pressure of the diversion pipe 210. That is: when the gluing parameters of the target part do not reach the expected range, adjust the flow and / or pressure of the diverter pipe 210, and detect the gluing parameters of the target part again. When the gluing parameters of the target part reach the expected range, stop adjusting the flow and / or pressure of the diverter pipe 210. When the gluing parameters of the target part do not reach the expected range, continue to adjust the flow and / or pressure of the diverter pipe 210 until the gluing parameters of the target part reach the expected range.

[0047] Optionally, the target part is a pole piece manufactured by wet coating or a pole piece manufactured by dry coating.

[0048] In the embodiment of the present application, the feeding mechanism 100 is a component for supplying rubber material. The feeding mechanism 100 can adopt various structural forms. For example, the feeding mechanism 100 includes components such as a storage barrel and a delivery pump, and the delivery pump delivers the rubber material in the storage barrel to each diversion pipe 210 of the diversion mechanism 200.

[0049] In the embodiment of the present application, the diverter mechanism 200 is a component for receiving the rubber material from the feeding mechanism 100 and delivering it to the discharging mechanism 300. The diverter pipe 210 of the diverter mechanism 200 is used for diversion. One end of the diverter pipe 210 is connected to the feeding mechanism 100, and the other end of the diverter pipe 210 is connected to the discharging pipe 310. The diverter pipe 210 and the discharging pipe 310 are arranged in a one-to-one correspondence. The diverter regulating assembly 220 of the diverter mechanism 200 is used to regulate the flow and / or pressure of the diverter pipe 210. Each diverter pipe 210 is provided with at least one diverter regulating assembly 220. The diverter regulating assembly 220 can adopt various structural forms. For example, the diverter regulating assembly 220 includes components such as a flow valve and a pressure valve to achieve the regulation of the flow and pressure of the diverter pipe 210.

[0050] In the embodiment of the present application, the discharge mechanism 300 is a component for receiving the rubber material from the diversion mechanism 200 and delivering it to the coating mechanism 400. The discharge mechanism 300 includes at least two discharge pipes 310, which are arranged in a one-to-one correspondence with the diversion pipes 210. In addition, the discharge mechanism 300 may also include components such as control valves, which are used to control the flow rate and pressure of the discharge pipes 310.

[0051] In the embodiment of the present application, the coating mechanism 400 is a component that is connected to each discharge pipe 310 and is used to apply glue to the target workpiece. The coating mechanism 400 can adopt various structural forms. For example, the coating mechanism 400 can be a slit coating head type or a dispensing head 440 type. The type of coating mechanism 400 is not specifically limited here.

[0052] In the embodiments of the present application, the online detection mechanism 500 is used to detect the gluing parameters of the target part and adjust the diversion adjustment assembly 220 based on the gluing parameters of the target part. The online detection mechanism 500 can adopt various structural forms. For example, the online detection mechanism 500 includes a controller 510 and various detectors. The various detectors are used to detect the gluing parameters of the target part. The controller 510 controls the diversion adjustment assembly 220 to adjust the flow rate and / or pressure of the diversion pipe 210. Optionally, the gluing parameters include geometric information such as the gluing thickness and gluing width.

[0053] The above-mentioned coating and dispensing device 10 utilizes the feeding mechanism 100 to supply glue, and the glue flows to each discharge pipe 310 through each branch pipe 210, and then flows to the coating mechanism 400, and is coated with glue on the target part through the coating mechanism 400. After the target part is coated with glue, the online detection mechanism 500 detects the coating parameters of the target part in real time, and adjusts the branch adjustment component 220 according to the coating parameters of the target part to continuously adjust the flow and / or pressure of the branch pipe 210 so that the coating parameters of the target part are in line with the expected range. Without manual intervention, online closed-loop adjustment of the glue discharge flow and / or glue discharge pressure can be achieved, which is beneficial to improving the glue coating consistency and uniformity of the target part.

[0054] According to some embodiments of this application, please refer to Figures 2 to 3 The shunt regulating assembly 220 includes a shunt cavity 221 and a first regulating member 222 . The shunt cavity 221 is disposed in the shunt pipe 210 and communicates with the shunt pipe 210 . The first regulating member 222 is fixed to the shunt cavity 221 and is used to regulate the pressure of the shunt pipe 210 .

[0055] It should be noted that during the dispensing process, the glue is supplied by the feeding mechanism 100, which then flows through the diversion pipes 210 to the discharge pipes 310. From the discharge pipes 310, the glue flows to the coating mechanism 400, where it is applied to the target object. During this process, the pressure in the diversion chamber 221 is adjusted by the first regulating member 222, thereby adjusting the pressure in the diversion pipes 210.

[0056] In the examples of this application, reference is made to Figure 6 and Figure 7 The diversion cavity 221 is a component disposed in and in communication with the diversion pipe 210. The diversion cavity 221 has a diversion inlet 221b and a diversion outlet 221c. The diversion inlet 221b is in communication with the diversion pipe 210, and the diversion outlet 221c is in communication with the discharge pipe 310. The diversion cavity 221 can adopt various structural forms. For example, the diversion cavity 221 includes an upper mold 221d and a lower mold 221e. Both the upper mold 221d and the lower mold 221e are structures with one side open. The open side of the upper mold 221d and the open side of the lower mold 221e overlap each other to form a receiving space for the rubber material to flow through.

[0057] In the embodiment of the present application, the first regulating member 222 is a component for regulating the pressure of the shunt pipe 210. The first regulating member 222 can adopt various structural forms. The first regulating member 222 can be a pressure regulating valve or other component for regulating pressure. The number of first regulating members 222 is not limited to one. When the number of first regulating members 222 is at least two, each first regulating member 222 can be located at a different position of the shunt cavity 221 to more flexibly regulate the pressure of the shunt pipe 210.

[0058] Through the above arrangement, during the dispensing process, the pressure in the diversion cavity 221 is adjusted by the first adjusting member 222, thereby adjusting the pressure of the diversion pipe 210 to effectively control the flow rate and flow velocity of the rubber material. The operation is convenient and the structural design is reasonable.

[0059] According to some embodiments of this application, please refer to Figure 3 and Figure 4 The first adjusting member 222 includes a valve body 222a, an adjusting portion 222b and a detecting portion 222c. The detecting portion 222c is fixed to the diverter cavity 221 and is used to detect the pressure of the diverter pipe 210. The valve body 222a is connected to the diverter cavity 221 and is used to adjust the pressure of the diverter pipe 210. The adjusting portion 222b is provided on the valve body 222a and is used to adjust the opening of the valve body 222a.

[0060] It can be understood that the pressure of the diverter pipe 210 is detected by the detection part 222c. When the pressure of the diverter pipe 210 does not reach the preset range, the control regulating part 222b regulates the opening of the valve body 222a and adjusts the space for the rubber material to pass through the diverter cavity 221 to achieve the regulation of the pressure of the diverter pipe 210. The valve body 222a is stopped from being adjusted until the pressure of the diverter pipe 210 reaches the preset range.

[0061] In the embodiments of the present application, valve body 222a is a component connected to diverter cavity 221 and used to regulate the pressure of diverter pipe 210. The valve body 222a and diverter cavity 221 can be connected in various ways. For example, the valve body 222a and diverter cavity 221 can be detachably connected by means of a snap connection, plug connection, or screw connection, or the valve body 222a and diverter cavity 221 can be non-detachably connected by means of riveting, welding, or the like. Optionally, valve body 222a is a constant pressure valve.

[0062] In the embodiment of the present application, the regulating portion 222b is a component provided on the valve body 222a and used to adjust the opening of the valve body 222a. The regulating portion 222b can adopt various structural forms. The regulating portion 222b is connected to the valve body 222a. Optionally, the regulating portion 222b is an electric proportional valve or other type of regulating valve.

[0063] In the embodiments of the present application, the detection portion 222c is a component fixed to the diversion cavity 221 and used to detect the pressure of the diversion pipe 210. The detection portion 222c and the diversion cavity 221 can be connected in various ways. For example, the detection portion 222c and the diversion cavity 221 can be detachably connected by means of a snap connection, plug connection, or screw connection, or the detection portion 222c and the diversion cavity 221 can be non-detachably connected by means of riveting, welding, etc. Optionally, the detection portion 222c is a pressure sensor.

[0064] Through the above-mentioned setting, the opening of the valve body 222a is adjusted by controlling the regulating part 222b, and the space for the rubber to pass through in the diversion cavity 221 is adjusted to achieve the regulation of the pressure of the diversion pipe 210. Without manual intervention, online closed-loop regulation of the glue discharge pressure can be achieved, which is convenient to operate and has a reasonable structural design.

[0065] According to some embodiments of this application, please refer to Figure 2 The shunt regulating assembly 220 further includes a second regulating member 223 , which at least partially extends into the shunt cavity 221 and is used to regulate the flow of the shunt pipe 210 .

[0066] It should be noted that during the dispensing process, the glue is supplied by the feeding mechanism 100, which then flows through the diversion pipes 210 to the outlet pipes 310. From the outlet pipes 310, the glue flows to the coating mechanism 400, where it is applied to the target object. During this process, the flow rate within the diversion cavity 221 is adjusted by the second regulating member 223, thereby adjusting the flow rate in the diversion pipes 210.
