As the heart of electrical devices, the performance, safety and durability of batteries are crucial. For batteries, precise glue coating process is one of the core factors to achieve stable, efficient and long-lasting operation of electric drive systems.

[0003] In the battery bonding process, it is usually difficult to control the shape and thickness of the glue after coating by manually applying the glue, resulting in poor subsequent bonding effect; and the gluing efficiency is low, especially in multi-directional gluing scenarios.

[0044] With the development of battery technology, batteries are used in more and more fields and are gradually replacing traditional fossil energy in the field of automobile power. Batteries can store chemical energy and controllably convert chemical energy into electrical energy. In recyclable batteries, the active materials can be activated by charging after discharge and continue to be used.

[0045] As the heart of an electric device, the performance, safety and durability of the battery are of vital importance. For batteries, precise glue coating is one of the core factors to ensure the stable, efficient and long-lasting operation of the electric drive system.

[0046] In the battery bonding process, it is usually difficult to control the shape and thickness of the glue after coating by manually applying the glue, resulting in poor subsequent bonding effect; and the gluing efficiency is low, especially in multi-directional gluing scenarios.

[0047] Based on the above considerations, the glue coating equipment provided in the present application includes a material plate mechanism and a glue scraping mechanism. The material plate mechanism is provided with an open portion for applying the glue to the workpiece to be glued. The glue scraping member of the glue scraping mechanism is movably arranged relative to the glue scraping surface of the material plate mechanism to fill the glue into the open portion, so that the shape and thickness of the glue after scraping can be defined by the shape and thickness of the open portion, that is, the shape and thickness of the glue layer coated on the workpiece to be glued can be defined by the open portion, thereby improving the accuracy of glue coating. In addition, the scraping mechanism of the glue coating equipment in the embodiment of the present application is provided with multiple scraping members, and the multiple scraping members can fill the glue into the open parts of different scraping surfaces of the material plate mechanism, so that the glue is coated on different surfaces of the workpiece to be glued, thereby realizing multi-directional gluing and improving the gluing efficiency; or the multiple scraping members fill the glue into the open parts of the same scraping surface of the material plate mechanism along different directions, thereby realizing multi-directional gluing, shortening the movement trajectory of the scraping members, further improving the gluing efficiency, and allowing the glue scraped out in the previous time to be used for the next gluing, thereby saving glue.

[0048] Among them, the glue coating equipment can be used for products that need to be glued, such as batteries. The battery can be used in electrical devices that use the battery as a power source or various energy storage systems that use the battery as an energy storage element. The electrical device can be, but is not limited to, a mobile phone, a tablet, a laptop, an electric toy, an electric tool, a battery car, an electric car, a ship, a spacecraft, and the like. Among them, the electric toy can include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, and the like, and the spacecraft can include airplanes, rockets, space shuttles, and spacecrafts, and the like.

[0049] In some embodiments, the battery may be an energy storage device, which includes an energy storage container, an energy storage cabinet, and the like.

[0050] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity.

[0051] In the embodiment of the present application, the battery cell may be a secondary battery, which refers to a battery cell that can be recharged to activate the active material after the battery cell is discharged and can continue to be used. Each battery cell may also be a primary battery.

[0052] In some embodiments, please refer to Figure 1 The battery 1 may be a battery pack, which includes a housing 10 and a battery cell 20 , wherein the battery cell 20 or a battery module is accommodated in the housing 10 .

[0053] In some embodiments, the housing 10 can be used as a part of the chassis structure of the vehicle. For example, a portion of the housing 10 can become at least a part of the bottom plate of the vehicle, or a portion of the housing 10 can become at least a part of the cross beam and longitudinal beam of the vehicle.

[0054] Please refer to Figure 1The battery 1 includes a housing 10 and a battery cell 20, and the battery cell 20 is accommodated in the housing 10. The housing 10 is used to provide a storage space for the battery cell 20, and the housing 10 can adopt a variety of structures. In some embodiments, the housing 10 may include a first part 11 and a second part 12, and the first part 11 and the second part 12 cover each other, and the first part 11 and the second part 12 jointly define a storage space for accommodating the battery cell 20. The second part 12 may be a hollow structure with one end open, and the first part 11 may be a plate-like structure, and the first part 11 covers the open side of the second part 12, so that the first part 11 and the second part 12 jointly define a storage space; the first part 11 and the second part 12 may also be hollow structures with one side open, and the open side of the first part 11 covers the open side of the second part 12. Of course, the housing 10 formed by the first part 11 and the second part 12 can be in a variety of shapes, such as a cylinder, a cuboid, etc.

[0055] In the battery 1, there can be multiple battery cells 20, and the multiple battery cells 20 can be connected in series, in parallel, or in mixed connection. Mixed connection means that the multiple battery cells 20 are both connected in series and in parallel. The multiple battery cells 20 can be directly connected in series, in parallel, or in mixed connection, and then the whole formed by the multiple battery cells 20 is accommodated in the housing 10; of course, the battery 1 can also be a battery module formed by connecting multiple battery cells 20 in series, in parallel, or in mixed connection, and then the multiple battery modules are connected in series, in parallel, or in mixed connection to form a whole, and accommodated in the housing 10. The battery 1 can also include other structures, for example, the battery 1 can also include a busbar component for realizing electrical connection between the multiple battery cells 20.

[0056] The battery cells 20 in the battery 1 are bonded to each other, and / or to the outer shell 10, and / or to the side plates and end plates to increase the stability of the internal components of the battery 1 and the reliability of the battery 1. Therefore, in the production process of the battery 1, it is necessary to use a glue coating process to coat the battery cells 20 and / or the outer shell 10 with glue.

[0057] In the related art, the glue is usually applied manually to the battery cell and the shell, and then the glue is scraped flat with a scraper. This method makes it difficult to control the state of the glue after scraping flat. If the glue after scraping flat is too thick or too thin, or the shape of the glue after scraping flat is greatly different from the preset shape, it will affect the subsequent bonding effect; and the glue coating efficiency is low.

[0058] Based on this, the present application proposes a gluing device. The gluing device described in the embodiment of the present application is suitable for the gluing process of components in batteries, and is also suitable for the gluing conditions of other workpieces to be glued.

[0064] In some embodiments, the material plate mechanism 101 includes a first material plate 12 having an open portion 11, and a plurality of scraping members 21 include a first scraping member 211 and a second scraping member 212 which are arranged at intervals along a first direction x on the side of the first material plate 12 away from the workpiece to be coated with glue; the first direction x is consistent with the moving direction of the first scraping member 211 and the second scraping member 212.

[0065] Among them, the first rubber scraper 211 and the second rubber scraper 212 are arranged at intervals along the moving direction of the first rubber scraper 211 and the second rubber scraper 212, so that the two can scrape the rubber at the gluing position on the first material plate 12 in different directions, so that the first rubber scraper 211 and the second rubber scraper 212 can respectively fill the rubber into the open part 11 along two opposite directions on the first direction x, and scrape the rubber protruding from the open part 11 from the open part 11 along the two opposite directions, which can improve the scraping efficiency of the rubber, and facilitate the rubber scraped from the open part 11 to be directly filled into other open parts 11, which can save rubber; and in this embodiment, the first rubber scraper 211 and the second rubber scraper 212 are arranged at intervals along the moving direction of the first rubber scraper 211 and the second rubber scraper 212, which can facilitate the unified movement of the first rubber scraper 211 and the second rubber scraper 212, can improve the driving efficiency, and can simplify the structure of the rubber scraping mechanism 201 and improve the accuracy of rubber scraping.

[0136] The scraper 21 of the scraper mechanism 201 moves relative to the scraper surface of the material plate mechanism 101 to fill the rubber into the open portion 11, so that the shape and thickness of the rubber after scraping can be defined by the shape and thickness of the open portion 11, that is, the shape and thickness of the rubber layer coated on the workpiece to be coated with glue can be defined by the open portion 11, thereby improving the accuracy of rubber coating. In addition, the scraper mechanism 201 of this embodiment is provided with a plurality of scrapers 21, and the plurality of scrapers 21 can fill the rubber into the open portions 11 of different scraper surfaces of the material plate mechanism 101, so that the rubber is coated on different surfaces of the workpiece to be coated with glue, realizing multi-directional glue coating, and improving the glue coating efficiency; or the plurality of scrapers 21 fill the rubber into the open portions of the same scraper surface of the material plate mechanism 101 in different directions, realizing multi-directional glue coating, shortening the movement trajectory of the scraper 21, and further improving the glue coating efficiency; and the rubber scraped out in the previous time can be continuously used for the next coating, and can save rubber.

[0137] In some embodiments, the material plate mechanism 101 includes a first material plate 12 with an open portion, and a plurality of rubber scrapers 21 include a first rubber scraper 211 and a second rubber scraper 212 arranged at intervals along a first direction x on a side of the first material plate 12 away from the workpiece to be coated with glue; the first direction x is consistent with the moving direction of the first rubber scraper 211 and the second rubber scraper 212. In this way, the rubber can be filled into the open portion in two opposite directions, and the rubber in the open portion 11 can be scraped flat, and the rubber protruding from the open portion 11 is scraped outwards to both sides by the first rubber scraper 211 and the second rubber scraper 212, respectively, to achieve two-way rubber scraping.

[0138] In some embodiments, the distance between a side of the first scraper 211 facing away from the second scraper 212 and the first material plate 12 gradually increases along the first direction x toward the second scraper 212, and the distance between a side of the second scraper 212 facing away from the first scraper 211 and the first material plate 12 gradually increases along the first direction x toward the first scraper 211, so that the scraping surface of the first scraper 211 is set at an obtuse angle to the first material plate 12, which can increase the scraping efficiency of the first scraper 211 on the rubber material on the first material plate 12, and the scraping surface of the second scraper 212 is set at an obtuse angle to the first material plate 12, which can increase the scraping efficiency of the second scraper 212 on the rubber material on the first material plate 12.

The scraping member 21 is controlled to move relative to the scraping surface along the second direction z perpendicular to the scraping surface, so that the contact force between the scraping member 21 and the scraping surface can be adjusted. When the contact force between the scraping member 21 and the scraping surface is greater than the friction force between the two, the scraping end of the scraping member 21 in contact with the scraping surface will slide relative to the scraping surface, thereby adjusting the angle between the scraping member 21 and the scraping surface; and the first driving component 22 drives the scraping member 21 to move along the second direction z to adjust the angle between the scraping member 21 and the scraping surface, without manual adjustment, which can further improve the accuracy of the angle adjustment, thereby improving the efficiency and accuracy of the glue coating.
