Description

Technical Field

[0001] The utility model relates to a surface insulation spray printing device for a battery cell, in particular to a surface insulation spray printing device compatible with square and cylindrical battery cells. Background Art

[0002] In the energy industry, power and energy storage batteries are typically square aluminum-cased or cylindrical. As market demands for battery cell insulation, voltage resistance, and structural strength continue to increase, traditional coating processes are no longer able to meet these demands. This has led to the emergence of a new insulating inkjet printing process, which can enhance the insulation and shear strength of the battery cell surface.

[0003] Existing inkjet printing methods for battery cells have numerous drawbacks. For example, the method of using a lower positioning assembly to clamp the battery cell while the upper nozzle assembly scans and prints line by line is generally only suitable for one type of battery cell: cylindrical or square. This requires manufacturers to have two types of printing equipment available simultaneously. The cylindrical printing equipment must be shut down when producing square cells, and the square printing equipment must be shut down when producing cylindrical cells. This situation not only results in low utilization of the printing equipment, but also requires frequent equipment changes depending on the battery cell production batch, which affects production efficiency and increases production costs. Utility Model Content

[0004] The purpose of the utility model is to provide a surface insulation spray printing device that is compatible with square and cylindrical battery cells, which effectively improves the utilization rate of the printing device and effectively reduces production costs.

[0005] In order to achieve the above-mentioned purpose, the surface insulation spray printing equipment compatible with square and cylindrical battery cells provided by the utility model includes a platform, a first clamp, a second clamp, a longitudinal drive mechanism, a cleaning device, a first lateral translation mechanism, a nozzle device, and a second lateral translation mechanism; the first clamp and the second clamp are arranged side by side laterally at the front end of the platform, and the longitudinal drive mechanism is arranged on the platform and drives the first clamp and the second clamp to move along the front and rear directions of the platform; the first lateral translation mechanism and the second lateral translation mechanism are both arranged laterally on the platform and are arranged in sequence from the front end to the rear end of the platform; the cleaning device is arranged at the output end of the first lateral translation mechanism and moves to the bottom of the battery cell under the drive of the first lateral translation mechanism and cleans the surface of the battery cell; the nozzle device is arranged at the output end of the second lateral translation mechanism and moves to the bottom of the battery cell under the drive of the second lateral translation mechanism and cleans the surface of the battery cell.

[0006] Compared to the prior art, the present invention utilizes a first clamp and a second clamp arranged side by side on the platform, with the first clamp holding the square battery cell and the second clamp holding the cylindrical battery cell. A longitudinal drive mechanism then simultaneously drives the first and second clamps to move longitudinally, allowing the first and second clamps to sequentially pass through a cleaning device and a nozzle device, achieving cleaning and inkjet printing. When passing through the cleaning device, the first lateral translation mechanism drives the cleaning device to move along the arrangement direction of the first and second clamps, thereby cleaning the surfaces of the square battery cell and / or cylindrical battery cell. Simultaneously, when passing through the nozzle device, the second lateral translation mechanism drives the nozzle device to move along the arrangement direction of the first and second clamps, thereby cleaning the surfaces of the square battery cell and / or cylindrical battery cell. Therefore, the present device can simultaneously or separately spray-print battery cells of different shapes, making it suitable for different types of battery cells. When producing different batches of battery cells with different shapes, there is no need to stop the machine for replacement, resulting in extremely high equipment utilization, effectively improving production efficiency, and reducing production costs.

[0007] Preferably, the first fixture includes a base, a first reference block, a first cylinder, a second reference block, and a second cylinder. The first reference block is fixed to the lateral side of the base, and the second reference block is fixed to the longitudinal side of the base. The first cylinder is disposed on the base and located on the side opposite the first reference block to push the battery cell toward the first reference block. The second cylinder is disposed on the base and located on the side opposite the second reference block to push the battery cell toward the second reference block. By providing the first and second reference blocks and utilizing the first and second cylinders to respectively push the battery cell toward the two reference blocks, automatic positioning can be achieved, resulting in a simple structure and convenient control.

[0008] Specifically, the first fixture also includes a first ink receiving tray, which is mounted on the base and located at the bottom of a cavity formed by the first reference block, the second reference block, the output end of the first cylinder, and the output end of the second cylinder. The first ink receiving tray collects excess ink produced by spraying and ink dripping from the battery cells, preventing ink from contaminating other fixture components and ensuring cleanliness and stable operation.

[0009] Specifically, the first fixture also includes a sensor, mounted on the base and located at the bottom of a cavity formed by the first and second reference blocks, the output end of the first and second cylinders, to detect whether the battery cell is properly installed. The sensor automatically detects the battery cell, preventing the fixture from being unloaded or being sprayed with ink, thereby ensuring the reliability and stability of the device.

[0010] Preferably, a curing device is further included, which is arranged after the nozzle device to cure the ink on the surface of the battery cell. By arranging the curing device, the curing speed of the battery cell can be accelerated, thereby improving production efficiency.

[0011] Specifically, the curing device includes a curing head and a third lateral translation mechanism. The third lateral translation mechanism is positioned transversely on the platform and behind the second lateral translation mechanism. The curing head is positioned at the output end of the third lateral translation mechanism and, driven by the third lateral translation mechanism, moves below the battery cell to cure the ink on the cell surface. By using the third lateral translation mechanism to drive the curing head, the curing head can cure battery cells of different shapes on the first and second fixtures, ensuring the device's compatibility with different battery cells.

[0012] Specifically, the curing device further includes a shielding plate, which is disposed at the output end of the third lateral translation mechanism. The shielding plate extends parallel to the arrangement direction of the first and second fixtures. The shielding plate is provided with openings corresponding to the battery cells on each fixture. During curing, the curing head covers the corresponding openings to cure the battery cells at the openings. Because the curing head emits strong curing light, this light can affect the ink and parts on the surfaces of adjacent battery cells. Therefore, by providing a shielding plate with openings at the positions of the battery cells, the shielding plate can cooperate with the curing head, thereby curing the battery cells at those positions while shielding the battery cells and parts at other positions, effectively protecting the other battery cells and surrounding parts.

[0013] Preferably, the device further includes an ink receiving device, located below and to one side of the nozzle assembly, to remove residual liquid from the nozzle of the nozzle assembly. Since residual liquid may drip onto the equipment or onto the next battery cell after spraying, this liquid may affect the spraying quality of the equipment and the battery cell. Therefore, by using the ink receiving device to remove residual liquid from the nozzle, the device and the battery cell can be protected, thereby improving the quality of the spraying.

[0014] Specifically, the ink receiving device includes a lifting drive mechanism, a horizontal drive mechanism, a second ink receiving tray, a brush head, and a lifting frame. The output end of the lifting drive mechanism is connected to the lifting frame, on which the second ink receiving tray is mounted. The horizontal drive mechanism is mounted on the lifting frame, and its output end is connected to the brush head, thereby driving the brush head to move above the second ink receiving tray. Utilizing the lifting and horizontal drive mechanisms, the brush head can be positioned close to the nozzle of the nozzle assembly during cleaning, ensuring reliable cleaning. However, during spraying, the brush head can be positioned away from the nozzle assembly to prevent interference with the nozzle assembly, thereby ensuring reliable and stable operation of the equipment.

[0015] Preferably, the apparatus further includes a CCD camera and a fourth lateral translation mechanism. The fourth lateral translation mechanism is disposed transversely on the platform and in front of the first lateral translation mechanism. The output end of the fourth lateral translation mechanism is connected to the CCD camera to drive the CCD camera to move to the corresponding battery cell in the fixture for imaging. Using the fourth lateral translation mechanism and the CCD camera to capture images, the actual outline size of the battery cell can be measured, thereby facilitating control of the direction and position of ink ejection from the printhead assembly, achieving precise printing.

[0024] In order to explain the technical content, structural features and effects achieved by the present invention in detail, the following is a detailed description in conjunction with the embodiments and the accompanying drawings.

[0025] like Figures 1 to 2 As shown, the surface insulation spray printing device 100 compatible with square and cylindrical battery cells of the present invention includes a platform 1, a first clamp 2, a second clamp 3, a longitudinal drive mechanism 4, a cleaning device 5, a first lateral translation mechanism 6, a nozzle device 7, and a second lateral translation mechanism 8. The first clamp 2 and the second clamp 3 are arranged side by side at the front end of the platform 1. The first clamp 2 is used to clamp the square battery cell, and the second clamp 3 is used to clamp the cylindrical battery cell. The longitudinal drive mechanism 4 is arranged longitudinally in the middle of the platform 1 and can drive the first clamp 2 and the second clamp 3 to move along the front and rear directions of the platform 1. The longitudinal drive mechanism 4 drives the first clamp 2 and the second clamp 3 by using a motor to drive a screw slider to slide on the platform 1. The first clamp 2 and the second clamp are arranged on the slider. The longitudinal drive mechanism 4 can also use a motor to drive a pulley, and use a belt to drive the slider to slide on the platform 1. The first and second lateral translation mechanisms 8 are both arranged transversely on the platform 1, in sequence from the front to the rear. The first and second lateral translation mechanisms 6 and 8 share the same structure, employing either a motor-driven lead screw slider or a motor-driven pulley with the pulley's belt driving the device for transverse movement. Furthermore, both the first and second lateral translation mechanisms 6 and 8 have lifting capabilities. The first lateral translation mechanism 6 drives the cleaning device 5 up and down, moving it closer to or further away from the battery cells on the fixture. The cleaning device 5 is located at the output end of the first lateral translation mechanism 6 and, driven by the first lateral translation mechanism 6, moves beneath the battery cells to clean their surfaces. The cleaning device 5 is a plasma cleaning device 5. Using a plasma cleaning device 5 improves the cleaning efficiency of the battery cells and further enhances the quality of the spray coating. The second lateral translation mechanism 8 drives the spray head device 7 up and down, moving it closer to or further away from the battery cells on the fixture. The nozzle device 7 is arranged at the output end of the second transverse translation mechanism 8 and is driven by the second transverse translation mechanism 8 to move to the bottom of the battery cell and clean the surface of the battery cell.

[0026] For example Figures 3 to 5As shown, the first fixture 2 includes a base 21, a first reference block 22, a first cylinder 23, a second reference block 24, and a second cylinder 25. The first reference block 22 is fixed to the lateral side of the base 21, and the second reference block 24 is fixed to the longitudinal side of the base 21. The first cylinder 23 is arranged on the base 21 and is located on the side opposite to the first reference block 22 to push the battery cell toward the first reference block 22. The second cylinder 25 is arranged on the base 21 and is located on the side opposite to the second reference block 24 to push the battery cell toward the second reference block 24. By providing the first reference block 22 and the second reference block 24, and using the first cylinder 23 and the second cylinder 25 to respectively push the battery cell toward the two reference blocks, the purpose of automatic positioning can be achieved, with a simple structure and convenient control. Specifically, the first fixture 2 also includes a first ink receiving tray 26 and a sensor 27. The first ink receiving tray 26 is disposed on the base 21 and is located at the bottom of the cavity formed between the first reference block 22, the second reference block 24, the output end of the first cylinder 23, and the output end of the second cylinder 25. The first ink receiving tray 26 collects excess ink produced by spraying and ink dripping from the battery cells, preventing ink from contaminating other fixture components and ensuring cleanliness and stable operation. The sensor 27 is disposed on the base 21 and is located at the bottom of the cavity formed between the first reference block 22, the second reference block 24, the output end of the first cylinder 23, and the output end of the second cylinder 25 to detect whether the battery cells are properly installed. The provision of the sensor 27 enables automatic detection of battery cells, preventing the fixture from being idle or being sprayed with ink, and ensuring the reliability and stability of the device. The second fixture 3 of this embodiment is a conventional fixture for holding cylindrical battery cells, which is well known to those skilled in the art and will not be described in detail here.

[0027] See also Figure 2 and Figure 4The surface insulation spray printing device 100 compatible with square and cylindrical battery cells also includes a curing device 9, which is arranged after the nozzle device 7 to cure the ink on the surface of the battery cell. By providing the curing device 9, the curing speed of the battery cell can be accelerated, thereby improving production efficiency. Specifically, the curing device 9 includes a curing head 91, a third lateral translation mechanism 92, and a shielding plate 93. The third lateral translation mechanism 92 is arranged horizontally on the platform 1 and is located after the second lateral translation mechanism 8. The third lateral translation mechanism 92 can drive the curing head 91 to move horizontally and rise and fall, so that the curing head 91 approaches or moves away from the battery cell on the fixture. The shielding plate 93 is arranged at the output end of the third lateral translation mechanism 92. The shielding plate 93 extends in a direction parallel to the arrangement direction of the first fixture 2 and the second fixture 3. The shielding plate 93 is provided with openings 931 corresponding to the battery cells on each fixture. The curing head 91 is located above the baffle 93. It is connected to the output end of the third lateral translation mechanism 92 and, driven by the third lateral translation mechanism 92, moves above the battery cells to cure the ink on the battery cell surfaces. Specifically, during curing, the curing head 91 covers the opening 931 corresponding to the baffle 93 to cure the battery cells at the opening 931. Because the curing head 91 emits strong curing light, this light can affect the ink and components on the surfaces of adjacent battery cells. Therefore, by providing the baffle 93 with openings 931 corresponding to the battery cells, the baffle 93 cooperates with the curing head 91, allowing the battery cells at that location to be cured while shielding the battery cells and components at other locations, effectively protecting the other battery cells and surrounding components. The curing head 91 of this embodiment is a curing lamp that emits ultraviolet light. Its structure is conventional and will not be described in detail here. By using the third lateral translation mechanism 92 to drive the curing head 91 to move, the curing head 91 can cure the battery cells of different shapes on the first fixture 2 and the second fixture 3, ensuring the compatibility of the equipment with different battery cells.

[0028] See also Figure 2 、 Figure 7 and Figure 8The surface insulation spray printing device 100 compatible with both square and cylindrical battery cells also includes an ink receiving device 10, which is located below and on one side of the nozzle device 7 to remove residual liquid from the nozzle of the nozzle device 7. Since residual oil will remain in the nozzle of the nozzle device 7 after spraying, this oil will drip onto the device or onto the next battery cell, thereby affecting the spraying quality of the device and the battery cell. Therefore, by using the ink receiving device 10 to remove residual liquid from the nozzle, it can protect the device and the battery cell, which is beneficial for improving the spraying quality. Specifically, the ink receiving device 10 includes a lifting drive mechanism 101, a horizontal drive mechanism 102, a second ink receiving tray 103, a brush head 104, and a lifting frame 105. The output end of the lifting drive mechanism 101 is connected to the lifting frame 105, and the second ink receiving tray 103 is located on the lifting frame 105. The lifting drive mechanism 101 is raised and lowered by a motor-driven screw slider. The horizontal drive mechanism 102 is mounted on the lifting frame 105, and its output end is connected to the brush head 104, driving the brush head 104 to move above the second ink receiving tray 103. The horizontal drive mechanism 102 is driven by a motor-driven lead screw slider. Utilizing the lifting drive mechanism 101 and the horizontal drive mechanism 102, the brush head 104 can be positioned close to the nozzle of the nozzle assembly 7 during cleaning, ensuring reliable cleaning. During spraying, the brush head 104 can be positioned away from the nozzle assembly 7 to prevent interference with the nozzle assembly, thus ensuring reliable and stable operation of the equipment.

[0029] For example Figure 1 and Figure 2 As shown, the surface insulation spray printing device 100 compatible with square and cylindrical battery cells also includes a CCD camera 110 and a fourth lateral translation mechanism 120. The fourth lateral translation mechanism 120 is arranged horizontally on the platform 1 and is located in front of the first lateral translation mechanism 6. The output end of the fourth lateral translation mechanism 120 is connected to the CCD camera 110 to drive the CCD camera 110 to move horizontally and lift vertically. Thus, it moves to the battery cell of the corresponding fixture to shoot. The structure of the fourth lateral translation mechanism 120 is the same as that of the first lateral translation mechanism 6. By using the fourth lateral translation mechanism 120 and the CCD camera 110 to shoot, the actual outline size of the battery cell can be measured, which is conducive to controlling the direction and position of the ink sprayed by the nozzle device 7 to achieve precise printing.

[0030] In summary, and in conjunction with the accompanying drawings, the working principle of the surface insulation spray printing device 100 compatible with square and cylindrical battery cells of the present invention is described in detail below:

[0031] First, the square battery cell is clamped on the first fixture 2, and the cylindrical battery cell is clamped on the second fixture 3. After that, the longitudinal drive mechanism 4 drives the first fixture 2 and the second fixture 3 to move longitudinally synchronously to the bottom of the CCD camera 110, and the fourth lateral translation mechanism 120 drives the CCD camera 110 to move to the corresponding fixture for shooting. Then, the longitudinal drive mechanism 4 drives the first fixture 2 and the second fixture 3 to move to the bottom of the cleaning device 5. The cleaning device 5 plasma cleans the battery cells on each fixture. After cleaning, the longitudinal drive mechanism 4 drives the first fixture 2 and the second fixture 3 to move to the bottom of the nozzle device 7. Driven by the second lateral translation mechanism 8, the nozzle device 7 sprays and prints the battery cells on the first fixture 2 and the second fixture 3 in turn. After spraying is complete, the longitudinal drive mechanism 4 drives the first and second fixtures 2 and 3 to move below the curing device 9. The third lateral translation mechanism 92 drives the shielding plate 93 and curing head 91 downward, bringing the shielding plate 93 closer to the battery cells. Simultaneously, the third lateral translation mechanism 92 drives the curing head 91 to move laterally to the opening 931 corresponding to the shielding plate 93 to cure the battery cells. Simultaneously, the second lateral translation mechanism 8 drives the printhead assembly 7 to move above the ink receiving device 10. The lifting drive mechanism 101 of the ink receiving device 10 drives the second ink receiving tray 103 and brush head 104 upward to approach the printhead of the printhead assembly 7. The horizontal drive mechanism 102 of the ink receiving device 10 then drives the brush head 104 to move, allowing it to brush ink from the printhead onto the second ink receiving tray 103. Once the battery cells are cured, they can be unloaded, and the longitudinal drive mechanism 4 returns the first and second fixtures 2 and 3 to their initial positions.

[0032] Compared with the prior art, the present invention arranges the first clamp 2 and the second clamp 3 side by side on the platform 1, uses the first clamp 2 to clamp the square battery cell, uses the second clamp 3 to clamp the cylindrical battery cell, and then uses the longitudinal drive mechanism 4 to simultaneously drive the first clamp 2 and the second clamp 3 to move longitudinally, so that the first clamp 2 and the second clamp 3 pass through the cleaning device and the nozzle device 7 in turn to achieve cleaning and inkjet. When passing through the cleaning device 5, the first lateral translation mechanism 6 is used to drive the cleaning device 5 to move along the arrangement direction of the first clamp 2 and the second clamp 3, so as to clean the surface of the square battery cell and / or the cylindrical battery cell. At the same time, when passing through the nozzle device 7, the second lateral translation mechanism 8 is used to drive the nozzle device 7 to move along the arrangement direction of the first clamp 2 and the second clamp 3, so as to clean the surface of the square battery cell and / or the cylindrical battery cell. Therefore, this equipment can realize the simultaneous or separate spray printing of battery cells with different shapes, and is suitable for different types of battery cells. When producing different batches of battery cells with different shapes, there is no need to stop the equipment to replace it, which improves the utilization rate of the equipment and reduces production costs.

[0033] The above disclosure is only a preferred embodiment of the present invention and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
