Description

Technical Field

[0001] The utility model relates to the field of UV printing, and specifically proposes a printing spraying device applied to a new energy power battery-UV insulating coating. Background Art

[0002] At present, with the popularization of new energy technologies, especially the pollution-free and recyclable technologies based on batteries, it has become a trend to use batteries as the main power source. To ensure electrical safety, the cells of power batteries need to be wrapped with PET "blue film", but with the replacement and optimization of battery types, the substantial increase in operating voltage and energy density, the existing insulation solutions can no longer meet the needs of the continuous development of power battery technology.

[0003] The most advanced cell insulation method is UV coating technology, which is generally superior to other technologies in terms of cost control and application: the main shortcoming of blue film coating is poor adhesion, which directly affects the safety and reliability of power batteries; epoxy coating and powder coating have relatively good adhesion, but have obvious deficiencies in production efficiency, insulation performance and edge coverage performance. UV insulation coating not only makes up for the shortcomings of "blue film", but also outperforms powder coating and epoxy coating in other key performances, and is gradually becoming the preferred option for existing insulation coatings.

[0004] However, there are still many areas that need to be improved and perfected in UV insulating coatings. For example, the current HVLP spraying process not only causes a large amount of material waste, but also requires the construction of an additional spraying workshop, which undoubtedly increases the switching cost for users to switch from "blue film" to UV insulating coatings.

[0005] In view of this, this patent application is proposed. Utility Model Content

[0031] Embodiment 1, as Figures 1 to 8 As shown, the present application proposes a side-spray printing device, which includes an ink circulation side-spraying module group 1 for spraying and printing a battery product 5 and a base assembly 3 that supports and fixes the battery product 5. The base assembly 3 is connected with a horizontal axis driving assembly 2 for driving the ink circulation side-spraying module group 1 to reciprocate along the horizontal axis, and a turntable assembly 4 for carrying and driving the ink circulation side-spraying module group 1 to reciprocate.

[0032] The ink circulation side spray module group 1 includes an installation frame composed of a nozzle fixing plate 6, a bottom plate 8 and a side plate 9 connected to each other. The diverter assembly 10 is suspended and connected to the bottom plate 8 through a diverter bracket 14. The diverter assembly 10 is connected to the diaphragm pump 11 through a temperature sensor signal control board 12 and a two-way solenoid valve 13, and the UV printing nozzle 7 is connected to the nozzle fixing plate 6 through a nozzle card fixing plate 15.

[0033] The horizontal axis driving assembly 2 includes a mounting plate 16 of a horizontal device, and a slide module fixing plate 19 for connecting the slide module 24 to drive the mounting plate to reciprocate in the horizontal direction, two sets of parallel sliders 16-1, and a lifting cylinder 21 are respectively arranged at the bottom of the mounting plate 16. The driving end of the lifting cylinder 21 passes through the mounting plate 16 and contacts the bottom of the turntable assembly 4.

[0034] Vertical plates 18 vertically connected by back triangular reinforcing ribs 17 are installed on both sides of the mounting plate 16 , and two groups of lifting sliders 20 are symmetrically arranged on opposite end surfaces of the vertical plates 18 on both sides.

[0035] The base assembly 3 includes a steel frame base 22, and two groups of horizontal slide rails 23 are arranged in parallel on both sides of the top of the steel frame base 22. The sliders 16-1 of the horizontal axis drive assembly 2 are respectively slidably buckled on the horizontal slide rails 23; at the bottom of the steel frame base 22, the first mounting plate 25 and the second mounting plate 26 are interconnected to form a bracket for vertically fixing the slide module 24, and the top driving end of the slide module 24 is driven in the horizontal direction to connect the slide module fixing plate 19.

[0036] Driven by the slide module 24, the horizontal axis driving assembly 2 moves as a whole along the horizontal slide rail 23, thereby realizing the overall reciprocating movement of the ink circulation side spray module 1 along the horizontal axis.

[0037] The turntable assembly 4 comprises a U-shaped frame formed by connecting two sets of bearing seat mounting plates 27 arranged vertically and a horizontal bottom plate 34;

[0038] A group of connecting shafts 28 are respectively provided on the opposite end surfaces of the two groups of bearing seat mounting plates 27, and a group of adapter plates 30 are respectively fixedly connected to the opposite ends of the two groups of connecting shafts 28, and a cross roller bearing 31 is provided on the inner ring of the adapter plate 30; the side plate 9 of the ink circulation side spray mold group 1 is fixedly connected to the adapter plate 30 along the horizontal axial direction by bolts; accordingly, a servo motor 32 for driving the connecting adapter plate 30 to rotate around the axial center of the connecting shaft 28 is provided on a group of bearing seat mounting plates 27; under the drive of the servo motor 32, the adapter plate 30 rotates around the horizontal axial direction while driving the rotation and positioning of the ink circulation side spray mold group 1 at different angles, thereby completing the spray printing on the surface of the battery cell products 5 with different specifications and external dimensions.

[0039] Two sets of vertical slide rails 35 are arranged on the outer side surface of each bearing seat mounting plate 27, and the lifting slider 20 is slidably buckled on the vertical slide rails 35; the lifting cylinder 21 of the horizontal axis driving assembly 2 can touch the horizontal bottom plate 34, and when the lifting cylinder 21 vertically pushes the mounting plate 34, the lifting slider 20 rises or falls along the vertical slide rails 35, thereby realizing the adjustment of the overall height of the ink circulation side spray mold group 1.

[0040] A vertical gap is maintained between the outer side of the side plate 9 of the ink circulation side spray mold assembly 1 and the inner side of the bearing seat mounting plate 27 of the turntable assembly 4, and a cleaning station 36 for cleaning the UV printing nozzle 7 is fixedly connected in the gap;

[0041] Before the spray printing operation, the cleaning station 36 is used to clean the UV print head 7 to ensure smooth printing of the surface of the subsequent battery product 5. Specifically, starting from the initial station, when the slide module 24 drives the horizontal axis drive assembly 2 to move along the horizontal slide rail 23, the ink circulation side spray module 1 reciprocates relative to the cleaning station 36, so that the cleaning station 36 cleans the outlet of the UV print head 7 and absorbs the stains and excess ink.

[0042] The side-jet printing device proposed in the present application is designed with a multi-directional driving and positioning structure for the ink circulation side-jet module 1 in the horizontal axial, vertical and axial rotation directions, so that it can effectively complete the spray printing on the surface of battery products 5 with multiple specifications, different appearance sizes, and even angled planes. The printing operation quality is high, and it is also conducive to cooperating with the implementation of the negative pressure and temperature stability of the ink circuit inside the ink circulation side-jet module 1 to prevent ink leakage and ink dripping during the movement and rotation process.

[0043] The above contents and the embodiments given in the accompanying drawings are only preferred solutions for achieving the purpose of the utility model. For those skilled in the art, they can be inspired by this and directly deduce other alternative structures that conform to the design concept of the utility model. Other structural features obtained thereby should also belong to the scope of the solution described in the utility model.
