[0036] The described features, structures, or characteristics can be combined in any suitable manner in one or more implementations. In the following description, numerous specific details are provided to enable a full understanding of the example implementations. One skilled in the relevant art will recognize, however, that the principles of the application can be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the application.

[0037] The following example describes an embodiment of a battery piece glue printing device of the present application. This example is only one embodiment of the present application, but the scope of protection of the present application is not limited thereto. All other embodiments obtained by those of ordinary skill in the art without creative labor should be covered within the scope of protection of the present application.

[0038] Please refer to Figures 1 to 17 According to the embodiment of the present application, a battery piece glue printing device is provided, comprising a glue point printing screen assembly 1, a glue scraping assembly 2, a glue filling assembly 3, and a screen lifting driving assembly 4. The screen lifting driving assembly 4 is used to drive the glue point printing screen assembly 1 to lift to adjust the height of the glue point printing screen assembly 1 relative to the battery piece 100. The glue point printing screen assembly 1 comprises a printing screen 14, which is a top-open box. A plurality of screen holes (not labeled in the figure) are formed in the bottom wall of the box, each of which can correspond to a preset glue point position on the top surface of the battery piece 100. The glue filling assembly 3 is used to provide glue liquid to the bottom wall of the box. The glue scraping assembly 2 is located in the opening area of the box and can be driven to reciprocate linearly along a preset direction (i.e., the glue scraping direction) to glue the glue liquid on the bottom wall to each of the preset glue point positions through each of the screen holes. It can be understood that the glue liquid leaked from each of the screen holes to the preset glue point position of the battery piece 100 will form a glue point after solidification.

[0039] In the technical scheme, each mesh hole arranged in an array on the printing screen 14 can correspond to a preset glue point position on the top surface of the battery piece 100, so that the battery piece glue printing device can realize the glue dispensing process on all glue points on one side of the battery piece 100 at one time, and the glue dispensing efficiency of the battery piece 100 is improved.

[0040] In one specific embodiment, the glue point printing screen assembly 1 comprises an outer frame 10, the screen lifting driving assembly 4 drives the outer frame 10 to realize the lifting of the glue point printing screen assembly 1, the glue scraping assembly 2 comprises a scraper assembly 21 and a scraper moving driving assembly 22 for driving the scraper assembly 21 to move linearly, and the scraper moving driving assembly 22 is fixedly connected to the outer frame 10.

[0041] In the technical scheme, the glue point printing screen assembly 1 and the scraper moving driving assembly 22 can be reliably connected through the outer frame 10, and reliable and stable linkage of the two components is formed, and the structure is simple.

[0042] As a specific embodiment, the scraper assembly 21 comprises a driving connecting plate 211, the scraper moving driving assembly 22 drives the scraper assembly 21 to move through the driving connecting plate 211, the scraper assembly 21 further comprises a scraper lifting driving assembly 212, a scraper mounting plate 213 and a scraper 214 connected to the bottom side of the scraper mounting plate 213, and the scraper lifting driving assembly 212 is used to drive the scraper mounting plate 213 to lift. In this way, the scraper lifting driving assembly 212 can drive the scraper 214 to lift, and then control the scraper 214 to rise to a certain height when there is no need to scrape glue, and control the scraper 214 to descend when the glue needs to be scraped.

[0043] In one preferred embodiment, the scraper mounting plate 213 is pivotally connected with a lifting rod (not marked in the figure) of the scraper lifting driving assembly 212, and specifically, a corresponding lifting plate is fixedly connected to the lifting rod, and the lifting plate and the scraper mounting plate 213 are hinged, so that the scraper mounting plate 213 can follow the lifting of the scraper lifting driving assembly 212 and also can follow the self-adaptive adjustment of the contact surface of the scraper 214 and the printing screen 14 by a certain angle, so as to ensure the accurate fitting of the scraper 214 and the top surface of the printing screen 14 and ensure smooth glue scraping.

[0044] The two ends of the width of the scraper 214 are respectively provided with glue retaining plates 215, each of which is connected to the two ends of the width of the scraper mounting plate 213, and the width of the glue retaining plate 215 is greater than the thickness of the scraper 214, and the height of the glue retaining plate 215 is greater than the height of the scraper 214, so that a glue retaining area is formed between the two glue retaining plates 215, the width of the glue retaining plate 215 is perpendicular to the width of the scraper 214, that is, in the use state, the two are arranged in T shape, so that the glue can be retained in the area where the scraper 214 is located, avoiding the situation that the glue moves to both sides of the printing screen 14 when the glue is scraped, so that the glue point cannot be perfectly printed due to lack of glue.

[0045] In some embodiments, each of the glue retaining plates 215 and the scraper mounting plate 213 is clamped with an elastic member 216, which can be a coil spring in particular, so as to ensure that the glue retaining plate 215 can abut against the top surface of the printing screen 14 by elastic action, and when the glue is scraped, the glue retaining plates 215 on both sides can retain a certain amount of glue in the area between the two glue retaining plates due to the distance protruding from the scraper 214, which can prevent the loss of glue, thereby ensuring the scraping effect.

[0046] As a preferred embodiment, the scraper moving drive assembly 22 and the scraper lifting drive assembly 212 both adopt linear motors, so as to make the device structure compact and relatively small in space occupation. The screen lifting drive assembly 4 can adopt a commercially available electric lifting module.

[0047] In some embodiments, the glue scraping assembly 2 has two groups, and the two groups of glue scraping assemblies 2 are arranged at intervals along the predetermined direction, and the glue filling assembly 3 is fixedly connected with the drive connecting plate 211 of the glue scraping assembly 2.

[0048] In the technical scheme, on the one hand, two groups of glue scraping assemblies 2 are arranged at intervals along the glue scraping direction, one of which can be selected according to the glue scraping direction to realize comprehensive glue scraping, for example, when the glue scraping direction is from left to right, the scraper 214 in the glue scraping assembly 2 on the left can be selected to be lowered and the other to be raised, so as to ensure the glue scraping effect on the left end position of the printing screen 14, and vice versa, when the glue scraping direction is from right to left, the scraper 214 in the glue scraping assembly 2 on the right can be selected to be lowered and the other to be raised, so as to ensure the glue scraping effect on the right end position of the printing screen 14; on the other hand, the glue filling assembly 3 is arranged between the two glue scraping assemblies 2 and connected as a whole, which can further simplify the structure design.

[0049] In some embodiments, the glue injection assembly 3 comprises a glue outlet pipe 31 extending along the width direction of the doctor blade 214, and a plurality of glue outlet holes (not shown in the figure) are formed on one side of the glue outlet pipe 31 facing the battery piece 100. An inlet pipe 32 is also arranged on the glue outlet pipe 31, and the inlet pipe 32 is used for controllable communication with an external glue supply source (not shown in the figure) to supplement the glue in time when the glue is lacking on the top surface of the printing screen 14. The aforementioned inlet pipe 32 is preferably two, and the two inlet pipes 32 are respectively arranged at the two end positions of the glue outlet pipe 31 to make the glue in the communication cavity be supplied more uniformly. It is worth emphasizing that after the amount of glue on both sides of the printing screen 14 is reduced, the glue can be supplied in time by the method of supplying glue and scraping to one side of the printing screen 14, which is beneficial to supplementing the glue on the screen in time.

[0050] As a preferred embodiment, the battery piece glue printing device further comprises a sealing cover 5 connected to the outer frame 10 and covering the opening area of the box to form a sealed structure of the box. An air suction pipe 51 is connected to the box, and an air inlet (not shown in the figure) is formed on the box for communication with the outside. Through the suction effect of the air suction pipe 51, the external cooling airflow enters the sealing cover 5 through the aforementioned air inlet to realize the supply of cooling airflow and extract the heat generated by friction during the glue scraping process, so as to ensure that the working environment inside the sealing cover 5 is in a low-temperature state, prevent the glue from denaturing, and ensure the stability of the glue.

[0051] In some embodiments, the glue point printing screen assembly 1 further comprises a first mounting plate 11, a second mounting plate 12 and a third mounting plate 13 arranged in layers from top to bottom. The outer frame 10 is slidingly connected with the first mounting plate 11, the first mounting plate 11 and the second mounting plate 12, and the second mounting plate 12 and the third mounting plate 13. The first mounting plate 11 can be driven to move linearly in a first direction, the second mounting plate 12 can be driven to move linearly in a second direction, the first direction and the second direction are perpendicular to each other, and the third mounting plate 13 can be driven to rotate in a horizontal plane. The printing screen 14 is connected to the bottom side end face of the third mounting plate 13.

[0052] In the technical solution, the first mounting plate 11, the second mounting plate 12 and the third mounting plate 13 are arranged in layers from top to bottom, and then the displacement of each layer plate body in different degrees of freedom is formed to realize the position adjustment of the printing screen 14 connected to the bottom side end face of the third mounting plate 13 in the horizontal plane. The control difficulty of the position adjustment of the printing screen 14 is simplified, and the space occupied by the driving components can be effectively reduced due to the independent driving of each corresponding mounting plate, which is convenient for the installation and use of parts.

[0053] The first direction is for example the X-axis direction in an XOY plane coordinate system, and the second direction is the Y-axis direction. The rotation of the third mounting plate 13 is a rotation around the O point.

The stator of the first linear motor 101 is fixed to the outer frame 10, and the rotor of the first linear motor 101 is fixedly connected to the first mounting plate 11. Thus, the first mounting plate 11 can be driven to move linearly in the first direction by a preset distance when the outer frame 10 is fixed. The outer frame 10 and the first mounting plate 11 are also connected by a first slide rail assembly 102 to reliably guide the linear movement of the first mounting plate 11. It can be understood that the first slide rail assembly 102 is a commercially available slide rail assembly, and multiple sets of the first slide rail assembly 102 can be arranged. Each set of the first slide rail assembly 102 can be arranged at the four corner regions of the top surface of the first mounting plate 11.

[0055] In a specific embodiment, a second linear motor 111 is arranged between the first mounting plate 11 and the second mounting plate 12. The stator of the second linear motor 111 is fixedly connected to the first mounting plate 11, and the rotor of the second linear motor 111 is fixedly connected to the second mounting plate 12. Thus, the second mounting plate 12 can be driven to move linearly in the second direction relative to the first mounting plate 11 by a preset distance. The first mounting plate 11 and the second mounting plate 12 are connected by a second slide rail assembly 112. The second slide rail assembly 112 can have the same structure as the first slide rail assembly 102, except that the installation position and the guiding direction are different. The sliding guiding tracks of the first slide rail assembly 102 and the second slide rail assembly 112 are straight lines.

[0059] Similar to the arrangement of the first linear motor 101 and the second linear motor 111, the third linear motor 121 also has two groups, and the two groups of the third linear motor 121 are respectively located at the opposite two side edges of the second mounting plate 12.
