[0030] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.
[0031] like Figure 1 、 Figure 2 and Figure 3 As shown, in one embodiment, a battery cell preparation device 10 is provided, wherein the battery cell includes a substrate 20 and a edging wrapped around the substrate 20, and the edging can be cured under light irradiation. The battery cell preparation device 10 includes a printing platform 100, a printing light source 200, and a reflector 300. The printing platform 100 is provided with a table 110 for supporting the substrate 20. The printing light source 200 is located on one side of the table 110 and is used to emit printing light toward the table 110. The reflector 300 is located on a side of the table 110 away from the printing light source 200. The reflector 300 is used to reflect the printing light to the edging on the side of the substrate 20 away from the printing light source 200 when the printing light is exposed to the side of the substrate 20 close to the printing light source 200.
[0032] In the above-described embodiment, when the cell preparation device 10 is used, a substrate 20 wrapped with uncured edging is placed on a table 110. The printing light source 200 then emits a printing light toward the table 110, so that a portion of the printing light is exposed to the side of the substrate 20 close to the printing light source 200 (i.e., the front side of the substrate 20), while another portion of the printing light is irradiated onto the reflector 300. The reflector 300 reflects the irradiated printing light onto the edging on the side of the substrate 20 away from the printing light source 200 (i.e., the back side of the substrate 20). This allows the edging to be cured under the irradiation of the printing light, achieving simultaneous curing of the edging while printing the pattern on the substrate 20. The present application combines the printing and edging processes into one process, thereby reducing the footprint of the cell preparation device 10 and improving the space utilization of the production line. Furthermore, by combining the printing and edging processes into one process, the total number of processes in the cell preparation device 10 is reduced, thereby reducing the preparation cycle of a single cell and the probability of failure of the cell preparation device 10, thereby improving the production efficiency of the production line.
[0033] The reflector 300 can be mounted on the printing platform 100 or on components around the printing platform 100. The reflector 300 can be configured as a reflective lens, a reflective prism, or other structures capable of reflecting printing light.
[0034] Specifically in this embodiment, the front and back sides of the substrate 20 are each provided with a edging area 21, and the edging wraps around the sidewalls of the substrate 20 and the two edging areas 21. The depth of the edging on the edging area 21 can be flexibly adjusted according to actual needs.
[0035] like Figure 3 and Figure 4 As shown, further, an annular groove 120 is provided on the table 110, and the reflector 300 is installed in the annular groove 120. When the substrate 20 is placed on the table 110, the edging is located at the notch of the annular groove 120 and is separated from the outer wall 121 of the annular groove 120 to form a light inlet. In this way, the printing light can pass through the light inlet and illuminate the reflector 300, ensuring that the reflector 300 can reflect the printing light to the edging on the back side of the substrate 20, thereby improving the reliability of the battery cell preparation device 10. In addition, the reflector 300 is located in the annular groove 120, so that the printing platform 100 can protect the reflector 300, preventing the reflector 300 from colliding with external objects and being damaged, thereby improving the service life of the battery cell preparation device 10. The edging is located at the notch of the annular groove 120, ensuring that uncured edging does not rub against the printing platform 100, thereby improving the reliability of the battery cell preparation device 10.
[0036] The reflector 300 can be installed in the annular groove 120 by snapping, plugging, gluing, magnetism or other methods.
[0037] Specifically, in the embodiment, the mesa 110 is arranged parallel to the horizontal plane. The printing light source 200 is located directly above the mesa 110, and the printing light is irradiated downward from directly above, so that part of the printing light can directly expose the front surface of the battery piece, and another part of the printing light can be reflected to the edge wrap on the back surface of the substrate 20 under the action of the reflection member 300, so that the edge wrap on the front surface and the back surface of the substrate 20 is solidified. Among them, due to the shielding of the mesa 110 on the back surface of the substrate 20, the printing light will not cause exposure effect on the back surface of the substrate 20.
[0038] As shown in Figure 3 and Figure 4 Optionally, the reflection member 300 is arranged in a triangular prism shape, the outer side wall 121 of the annular groove 120 is arranged in a rectangular shape along the cross section perpendicular to the extending direction of the annular groove 120, two of the three side surfaces of the reflection member 300 are respectively attached to the outer side wall 121 of the annular groove 120 and the bottom wall of the annular groove 120, and the other one of the three side surfaces of the reflection member 300 is arranged as the reflection surface 310. In this way, the outer side wall 121 and the bottom wall of the annular groove 120 can both play a positioning role on the reflection member 300, so as to ensure that the reflection member 300 is installed at the predetermined position in the annular groove 120, and further ensure that the reflection member 300 can accurately reflect the printing light to the edge wrap on the back surface of the substrate 20, thereby improving the reliability of the battery piece preparation device 10.
[0039] Specifically, in the embodiment, the reflection member 300 can be arranged as a right-angle triangular prism. Along the depth direction of the annular groove 120, the projection area of the light inlet is located in the projection area of the reflection surface 310. In other embodiments, the reflection member 300 can also be arranged as a right-angle triangular prism with a mirror piece installed on the inclined surface.
[0040] As shown in Figure 3 and Figure 5As shown, the reflector 300 comprises a first section 320, a second section 330, a third section 340 and a fourth section 350, the two ends of the first section 320, the two ends of the second section 330, the two ends of the third section 340 and the two ends of the fourth section 350 are provided with 45° chamfered corners, the two ends of the first section 320 are respectively spliced with one end of the second section 330 and one end of the fourth section 350, and the two ends of the third section 340 are respectively spliced with the other end of the second section 330 and the other end of the fourth section 350. In this way, the shapes of the two ends of the first section 320, the shapes of the two ends of the second section 330, the shapes of the two ends of the third section 340 and the shapes of the two ends of the fourth section 350 are the same, which facilitates the manufacturing and assembly of the reflector 300, and the reflective surfaces 310 on the first section 320, the reflective surfaces 310 on the second section 330, the reflective surfaces 310 on the third section 340 and the reflective surfaces 310 on the fourth section 350 can be spliced in sequence to form a ring-shaped whole, and there is no dead angle at the splicing positions of the first section 320 and the second section 330 and the fourth section 350 and the splicing positions of the third section 340 and the second section 330 and the fourth section 350, thereby improving the aesthetics and practicability of the battery piece preparation device 10.
[0041] Among them, the chamfered corner angles of the two ends of the first section 320, the two ends of the second section 330, the two ends of the third section 340 and the two ends of the fourth section 350 can be flexibly adjusted according to the actual use needs, as long as the structure after splicing of the first section 320, the second section 330, the third section 340 and the fourth section 350 can reflect the printing light to all the edges of the back of the substrate 20.
[0042] Optionally, the outer side wall 121 of the annular groove 120 and / or the bottom wall of the annular groove 120 is provided with a first fixing part, and the reflector 300 is provided with a second fixing part, and the first fixing part and the second fixing part are detachably connected. In this way, by replacing reflectors 300 with different inclination angles, the reflection position of the printing light can be adjusted, ensuring that battery pieces of different sizes can print patterns on the substrate 20 while completing the edge curing, thereby improving the applicability of the battery piece preparation device 10.
[0043] Specifically in this embodiment, the first section 320, the second section 330, the third section 340 and the fourth section 350 are all provided with second fixing parts, the number of first fixing parts is the same as the number of second fixing parts, and each first fixing part is detachably connected with each second fixing part.
[0044] In one embodiment, the table top 110 is provided with an adsorption part for adsorbing the substrate 20. In this way, the adsorption part can fix the substrate 20 on the table top 110, ensuring that the substrate 20 does not move on the table top 110 when printing patterns, thereby improving the reliability of the battery piece preparation device 10.
[0045] Specifically, in the embodiment, the suction part can be a vacuum suction hole. The number of the suction part is at least one, and each suction part is located on the inner side of the annular groove 120.
[0046] As shown in Figure 1 Optionally, the battery piece preparation device 10 further comprises a printing mask 400, which is located between the printing light source 200 and the table top 110. In this way, different printing masks 400 can be replaced to print different patterns on the substrate 20, thereby improving the practicability of the battery piece preparation device 10.
[0047] As shown in Figure 1 and Figure 2 In one embodiment, the battery piece preparation device 10 further comprises a moving mechanism 500, which is in transmission connection with the printing platform 100, so that the printing platform 100 can reciprocate between the feeding station, the printing station and the discharging station.
[0048] The moving mechanism 500 can be any moving driving structure in the prior art.
[0049] As shown in Figure 1 and Figure 2 Optionally, the battery piece preparation device 10 further comprises a feeding mechanism 600, which is used to feed the substrate 20 to the table top 110 when the printing platform 100 moves to the feeding station. The battery piece preparation device 10 further comprises a discharging mechanism 700, which is used to discharge the substrate 20 on the table top 110 when the printing platform 100 moves to the discharging station.

[0050] The feeding mechanism 600 can be any structure for feeding the substrate 20 in the prior art. The discharging mechanism 700 can be any structure for discharging the substrate 20 in the prior art. Specifically, in the embodiment, the feeding mechanism 600 and the discharging mechanism 700 are respectively located at both ends of the moving mechanism 500. The printing light source 200 is located between the feeding mechanism 600 and the discharging mechanism 700.
[0051] As shown in Figure 1 and Figure 2 In one embodiment, the battery piece preparation device 10 further comprises an edge wrapping mechanism 800, which is used to wrap the light curing glue around the substrate 20 to form an edge wrapping.
[0052] The edge wrapping mechanism 800 can be any structure for wrapping the light curing glue around the substrate 20 in the prior art.
[0053] Specific to the embodiment, the light-curing glue is set as the photosensitive glue. The edge wrapping mechanism 800 is used to wrap the photosensitive glue around the substrate 20 to form an edge wrapping. The feeding mechanism 600 is used to feed the substrate 20 wrapped with the uncured edge wrapping around the four sides to the table top 110 when the printing platform 100 moves to the feeding station.

The driving assembly is in transmission connection with the moving platform 830, so that the moving platform 830 can pass through the first edge wrapping wheel set 810 and the second edge wrapping wheel set 820. The first edge wrapping wheel set 810 is used to wrap the photosensitive glue on the opposite two sides of the substrate 20. The second edge wrapping wheel set 820 is used to wrap the photosensitive glue on the remaining two sides of the substrate 20.
[0055] Specific to the embodiment, when it is needed to wrap the photosensitive glue around the substrate 20, first, the substrate 20 is placed on the moving platform 830 correspondingly. The driving assembly drives the moving platform 830 to pass through the first edge wrapping wheel set 810. In the process that the moving platform 830 drives the substrate 20 to pass through the first edge wrapping wheel set 810, the first edge wrapping wheel set 810 wraps the photosensitive glue on the two long side edges of the substrate 20. Then, the moving platform 830 drives the substrate 20 to rotate by 90°. Finally, the driving assembly drives the moving platform 830 to pass through the second edge wrapping wheel set 820. In the process that the moving platform 830 drives the substrate 20 to pass through the second edge wrapping wheel set 820, the second edge wrapping wheel set 820 wraps the photosensitive glue on the two short side edges of the substrate 20. The photosensitive glue on the two long side edges of the substrate 20 and the photosensitive glue on the two short side edges of the substrate 20 are correspondingly connected to form the uncured edge wrapping.
