DETAILED DESCRIPTION

[0030] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0031] In order to illustrate the utility model scheme, the following will be combined with the attached Figures 1 to 5 This will be described by way of examples.

[0032] like Figure 1 As shown, according to an embodiment of the present application, a battery cell processing fixture can realize multiple process assistance such as core fixing, core gluing, film fixing and film gluing of battery cells, including a bottom plate 110, a first side plate 120 and a second side plate 130. As shown in the figure, the bottom plate 110 has a first direction (x direction) dimension, a second direction (y direction) dimension and a third direction (z direction) dimension, wherein the first direction, the second direction and the third direction are perpendicular to each other. The first side plate 120 and the second side plate 130 are arranged oppositely on both sides of the bottom plate 110 in the second direction, that is, they are arranged oppositely on the two side edges of the bottom plate 110 along the second direction, and are rotatably connected to the bottom plate 110 respectively to form fixed ends of the first side plate 120 and the second side plate 130, and the end opposite to the fixed end forms a free end. The first side panel 120 and the second side panel 130 can be opened and closed by rotating along the fixed end. In the open state, the first side panel 120 and the second side panel 130 are in the same plane as the bottom panel 110. In the closed state, the first side panel 120 and the second side panel 130 rotate to a closed state facing each other and are both perpendicular to the bottom panel 110, that is, the first side panel 120 and the second side panel 130 can both rotate at a certain angle, and the rotation angle range is 0-90°. In a specific example, the first side panel 120 and the second side panel 130 are connected to the bottom panel 110 through a hinge shaft 150, and the first side panel 120, the second side panel 130 and the bottom panel 110 are all provided with through holes matching the hinge shaft 150.

[0033] According to one embodiment of the present application, at least one positioning mechanism is provided at the free end of the first side plate 120 or the free end of the second side plate 130 for positioning the battery cell to be processed. At least one air-avoiding mechanism for gluing the battery cell to be processed is provided at the free end of the first side plate 120 and the free end of the second side plate 130. Figure 1 As shown, at least one positioning mechanism is provided at the free end, so that when the first side plate 120 and the second side plate 130 are in an open state, the positioning mechanism can limit the battery cell to be processed in the second direction, so that when the first side plate 120 and the second side plate 130 are closed, the positioning mechanism can clamp and fix the battery cell to be processed, preventing the battery cell to be processed from being displaced, which affects the accuracy of core closing, film coating or gluing. At least one space-avoiding mechanism is provided at the free end of the first side plate 120 and the second side plate 130, which reserves operating space for gluing, facilitates gluing on both sides of the battery cell after core closing or film coating, avoids moving the battery cell after core closing or film coating for the second time, which increases the process, and prevents the battery cell to be processed from being displaced, which affects the accuracy of core closing, film coating or gluing.

[0034] Furthermore, the first side panel 120 and the second side panel 130 also include a connecting end, wherein the connecting end of the first side panel 120 connects the fixed end and the free end of the first side panel 120 along two sides of the first side panel 120 in the first direction. The connecting end of the second side panel 130 connects the fixed end and the free end of the second side panel 130 along two sides of the second side panel 130 in the first direction. At least one positioning mechanism for positioning the battery cell to be processed is disposed on the connecting end of the first side panel 120 or the second side panel 130. At least one air avoidance mechanism for gluing the battery cell to be processed is correspondingly disposed on the connecting end of the first side panel 120 and the second side panel 130. Figure 1 As shown, at least one positioning mechanism is provided at the connection end, so that when the first side panel 120 and the second side panel 130 are in an open state, the positioning mechanism can limit the battery cell to be processed in the first direction. In addition, it can be understood that the connection end is provided with at least one positioning mechanism or air avoidance mechanism, which has the same effect as the positioning mechanism or air avoidance mechanism provided at the free end as mentioned above, and will not be repeated here.

[0035] In a specific example, the first side plate 120 and the second side plate 130 are both provided with positioning mechanisms. For the sake of convenience, the positioning mechanism on the first side plate 120 is the first positioning mechanism 122, the positioning mechanism on the second side plate 130 is the second positioning mechanism 132, the air avoidance mechanism on the first side plate 120 is the first air avoidance mechanism 121, and the air avoidance mechanism on the second side plate 130 is the second air avoidance mechanism 131. Figure 1As shown, the other three sides of the first side plate 120 (i.e., the free end and the connection end of the first side plate 120) except the side connected to the bottom plate 110, each side is provided with at least one first air avoidance mechanism 121, and the second side plate 130 is provided with a second air avoidance mechanism 131 corresponding to the first air avoidance mechanism 121 on the first side plate 120, so that when the first side plate 120 and the second side plate 130 are closed, the first air avoidance mechanism 121 and the second air avoidance mechanism 131 correspond one to one, so as to complete the gluing operation on the battery cell to be processed. Among them, the gluing operation can be performed on the battery cell after the core is combined, the battery cell coated with mylar film (polyester film) or other similar operations. The gluing is completed under the clamping of the battery cell processing fixture, which simplifies the gluing operation and improves the gluing efficiency and gluing quality.

[0036] In this embodiment, the free ends and fixed ends of the first side plate 120 and the second side plate 130 are both provided with positioning mechanisms, such as Figure 1 As shown, the first side plate 120 is provided with a first positioning mechanism 122 for positioning the battery cell to be processed, and the second side plate 130 is provided with a second positioning mechanism 132, so that when the first side plate 120 and the second side plate 130 are closed, the battery cell to be processed is clamped and positioned by the first positioning mechanism 122 and the second positioning mechanism 132. It can be understood that in other embodiments, the positioning mechanism can also be provided only on the first side plate 120 or the second side plate 130, that is, the positioning mechanism is provided only on one side plate, and the other side plate is not provided with a positioning mechanism, as long as the positioning mechanism can achieve the positioning of the battery cell to be processed when the first side plate 120 and the second side plate 130 are closed.

[0037] Furthermore, the first direction intersects with the third direction or the second direction intersects with the third direction to form a symmetry plane, and the symmetry plane passes through the center line of the bottom plate, such as Figure 1 As shown, the second air avoidance mechanism 131 and the first air avoidance mechanism 121 are symmetrically arranged relative to the symmetry plane, and the second positioning mechanism 132 and the first positioning mechanism 122 are symmetrically arranged relative to the symmetry plane, so as to achieve a better gluing and limiting effect on the processed battery cells. Of course, in some embodiments, the second positioning mechanism 132 and the first positioning mechanism 122 can also be arranged in an asymmetrical staggered manner, as long as the first side plate 120 and the second side plate 130 are closed, the second positioning mechanism 132 cooperates with the first positioning mechanism 122 to achieve the positioning of the battery cells to be processed, which is not limited here.

[0038] According to one embodiment of the present application, the first positioning mechanism 122 is a first boss protruding from the first side plate 120. Specifically, it is realized by protruding toward the side where the battery cell to be processed is placed. The first boss is arranged on the free end and the connecting end of the first side plate 120, and is used to position the components such as the battery cell to be processed, and avoid the first air avoidance mechanism 121. The first positioning mechanism 122 forms a groove limiting space on the first side plate 120, that is, a first positioning groove, which can achieve functions such as limiting the battery cell and folding the short sides of the battery cell film (Mayl ar film) on both sides during the battery cell processing. It should be noted that the first boss is not limited to being separated at the first air avoidance mechanism 121. The first boss can be continuously arranged at other positions, or it can have a gap, for example Figure 1 As shown, the first boss at the free end is both continuous and has a notch, there is a continuous boss between two adjacent first space avoiding mechanisms 121, and there are bosses with notches on both sides of the first space avoiding mechanisms 121. The notches can reduce the material of the clamp and save costs, while also making the clamp lightweight, thereby facilitating manual operation; in addition, it can be understood that the notches can also be used to observe the alignment effect of the edges of the battery cells after they are assembled, coated or glued.

[0039] The second positioning mechanism 132 is a second boss protruding from the second side plate 130. Specifically, the second positioning mechanism 132 forms a groove limiting space on the second side plate by protruding toward the side where the battery cell to be processed is placed, that is, the second positioning groove, which can also achieve the functions of limiting the battery cell and folding the short sides of the battery cell membrane during the battery cell processing. In this embodiment, the first boss and the second boss are arranged relative to each other, and have the same shape and size. It can be understood that the second boss is not limited to being separated at the second air avoidance mechanism 131. The second boss can be arranged continuously at other positions, or it can have a notch. The specific arrangement can refer to the first boss, and will not be repeated here. The first positioning groove and the second positioning groove limit the battery cell to be processed when the battery cell processing fixture is closed, keep the battery cell edges neat, make the battery cell measurement size accurate, and obtain more accurate battery cell test data on the pilot line, which can effectively reduce the complexity of the debugging process and speed up the battery mass production process.

[0040] According to other embodiments of the present application, the first positioning mechanism 122 and the second positioning mechanism 132 may also be asymmetrically arranged with different sizes and shapes. The first positioning mechanism 122 and the second positioning mechanism 132 may adopt various feasible boss structures, or other feasible structures other than the boss structure.

[0041] like Figure 2As shown, according to an embodiment of the present application, the battery cell processing fixture further includes an opening and closing mechanism. The opening and closing mechanism is arranged on the outside of the battery cell processing fixture (i.e., the side opposite to the position of the battery cell to be processed), and is connected to the first side plate 120 at the surface of the first side plate 120 opposite to the surface where the first positioning mechanism 122 is arranged, and is connected to the second side plate 130 at the surface of the second side plate 130 opposite to the surface where the second positioning mechanism 132 is arranged, and is used to control the opening and closing of the first side plate 120 and the second side plate 130. Figure 2 In the example shown, the opening and closing mechanism includes a connecting structure, a pull rod 144 and a handle 145. One end of the connecting structure is movably connected to the first side panel 120 and the second side panel 130 respectively, and the other end of the connecting structure is movably connected to the pull rod 144. One end of the pull rod 144 is fixedly mounted on the base plate 110, and the other end of the pull rod 144 is fixedly connected to the handle 145.

[0042] Specifically, the connection structure includes a connection member 141, a connection arm 142, and a retractable cantilever 143, wherein the number of the connection member 141, the connection arm 142, and the retractable cantilever 143 can be set to two, and the two connection members 141 are symmetrically fixedly installed on the outer sides of the first side plate 120 and the second side plate 130, respectively, and are usually set at the center. One end of each of the two connection arms 142 is movably connected to the two connection members 142 through a hinge pin 146, and one end of each of the two retractable cantilever arms 143 is connected to the other end of the two connection arms 142 through a hinge pin 146. The pull rod 144 is in the same plane as the two connection members 141, and one end of the pull rod 144 is fixedly installed at the bottom of the base plate 110, and is movably connected to the other end of the retractable cantilever arm 143 through a hinge pin 146, and the other end of the pull rod 144 is fixedly connected to the handle 145.

[0043] like Figure 3 As shown, by pulling the handle 145, the pull rod 144 will pull the bottom plate 110, so that the bottom plate 110 has a force to move outward, and the corresponding first side plate 120 and the second side plate 130 have a force to move inward, and then the first side plate 120 and the second side plate 130 will rotate around the hinge shaft 150. Further, the connecting arm 142 and the retractable cantilever 143 that are movably connected to the first side plate 120 and the second side plate 130 will move synchronously, so that the first side plate 120 and the second side plate 130 can be closed, and the core closing, film coating, gluing and other operations can be completed. It can be understood that by pushing the handle 145, the first side plate 120 and the second side plate 130 can be opened. The principle is opposite to that when the handle 145 is pulled, and it will not be repeated here, so as to complete the material discharge and material collection. The opening and closing mechanism makes the opening and closing operation of the battery processing fixture simple and improves the efficiency of battery processing.

[0044] According to one embodiment of the present application, a third positioning mechanism 164 is provided at both ends of the base plate 110 in the first direction, and the third positioning mechanism 164 protrudes toward the side where the battery cell to be processed is placed. In a specific example, the third positioning mechanism 164 is a boss structure, and the boss structure is trapezoidal. In other specific examples, the third positioning mechanism 164 can also be semicircular or rectangular. Furthermore, in order to prevent the first positioning mechanism 122 and the second positioning mechanism 134 on both sides of the third positioning mechanism 164 from conflicting with the third positioning mechanism 164 when the first side panel 120 and the second side panel 130 are closed, thereby affecting the closed state of the first side panel 120 and the second side panel 130, the first positioning mechanism 122 and the second positioning mechanism 132 on both sides of the third positioning mechanism 164 can be set to a shape that does not conflict with the third positioning mechanism 164 when the first side panel 120 and the second side panel 130 are closed, or the first positioning mechanism 122 and the second positioning mechanism 132 near the third positioning mechanism 164 can be removed, so that an avoidance gap is set between the third positioning mechanism 164 and the first positioning mechanism 122 adjacent thereto, and an avoidance gap is also set between the third positioning mechanism 164 and the second positioning mechanism 132 adjacent thereto. Since the avoidance gap is set, it can be avoided that the third positioning mechanism 164 conflicts with the first positioning mechanism 122 and the second positioning mechanism 132 when the first side panel 120 and the second side panel 130 are closed.

[0045] like Figure 4 As shown, further, the battery processing fixture also includes an adjusting member, which is connected to the third positioning mechanism 164 and is used to adjust the distance between the third positioning mechanisms 164 at both ends of the bottom plate 110. In a specific example, the bottom plate 110 is provided with through holes 161 connecting the two ends of the third positioning mechanism 164 along the first direction, and the third positioning mechanisms 164 at both ends of the bottom plate 110 are connected by adjusting members arranged in the through holes 161. The distance between the third positioning mechanisms 164 at both ends can be adjusted by the adjusting member, so that the distance between the two third positioning mechanisms 164 can be adjusted to be greater than the length of the bottom plate 110, so that when the battery cell is closed, a battery cover slightly longer than the battery cell can be placed. In a specific example, the adjusting member includes two connecting shafts 163 connecting the two third positioning mechanisms 164, and a spring 162 connecting the two connecting shafts 163, and the distance between the two third positioning mechanisms 164 is adjusted by stretching the spring 162, and the two third positioning mechanisms 164 are just clamped by the spring elastic force. The placed battery cover.

[0046] Back to Figure 1According to another embodiment of the present application, a cover plate avoidance groove 171 is further provided at the free end of the first side plate 120 or the free end of the second side plate 120. By providing the cover plate avoidance groove 171, the battery cover plate can be placed in the cover plate avoidance groove 171 perpendicular to the first side plate 120 or the second side plate 130 during the cell coating process. When the first side plate 120 and the second side plate 130 are closed, the battery cover plate is just clamped in the cover plate avoidance groove 171 of the first side plate 120 and the second side plate 130, so as to avoid that when the first side plate 120 and the second side plate 130 are closed, the size of the battery cover plate is slightly larger than the size of the cell body, resulting in the first side plate 120 and the second side plate 130 being unable to be completely closed, thereby failing to achieve a tight clamping of the cell and the coating, resulting in a reduction in the cell coating accuracy. Furthermore, the cover plate avoidance groove 171 can also be symmetrically provided at the free end of the first side plate 120 and the free end of the second side plate 130 to achieve positioning of the battery cover plate.

[0047] According to another aspect of the present application, a cell coating film 200 is provided, which is suitable for the cell processing fixture 100, and the cell coating film provided by the present application is used to coat the cell through the cell processing fixture. Figure 5 As shown, according to one embodiment of the present application, the battery cell coating film includes: a bottom film area 210 with flow holes, a side film area 220, a side film area 230 and a bottom film area 240. When the battery cell coating film is suitable for the above-mentioned battery cell processing fixture, the bottom film area 210 corresponds to the bottom plate 110 of the battery cell processing fixture, and there are two side film areas 220, which correspond to the first side plate 120 and the second side plate 130 respectively. The side film area 230 is connected to the two sides of the side film area 220 perpendicular to the connection line between the side film area 220 and the bottom film area 210, and the bottom film area 240 is connected to the two sides of the bottom film area 210 perpendicular to the connection line between the side film area 220 and the bottom film area 210. It can be understood that the battery cell coating film 200 can also omit the bottom film area 240, and after coating, only the side film area 230 is used to achieve the coating of the battery cell side.

[0048] Furthermore, in the process of assembling the battery cells, the battery cells to be processed are placed on the battery cell processing fixture, the battery cover is attached to the bottom plate 110, and the placed battery cover is just clamped by the third positioning mechanism 164, and the battery cells on both sides of the battery cover are symmetrically laid on the first side plate 120 and the second side plate 130, respectively, and the battery cells are clamped and positioned by the first positioning mechanism 122 on the first side plate 120 and the second positioning mechanism 132 on the second side plate 130. When the opening and closing mechanism is pulled, the battery cell processing fixture can clamp the battery cells to be assembled, thereby automatically folding the battery cells to achieve the assembling of the battery cells. After the assembling is completed, the gluing operation is performed at the positions of the first air-avoiding mechanism 121 and the second air-avoiding mechanism 131, thereby achieving the assembling and gluing process, so as to ensure the fixation and retention of the battery cells after the assembling, so as to improve the assembling efficiency of the battery cells and ensure the neatness of the edges of the battery cells after the assembling. It is understandable that the gluing operation can be performed only on the top ends relative to the battery cover, or can be performed on the sides at the same time.

[0049] Furthermore, during the cell wrapping process, the cell wrapping film is spread flat on the cell processing fixture, and at the same time, the first positioning mechanism 122 on the first side plate 120 and the second positioning mechanism 132 on the second side plate 130 can pre-position the cell wrapping film, and then the cell to be processed is placed vertically, and the bottom film area 210 of the cell wrapping film 200 is adhered to the bottom of the cell to be processed under the action of the bottom plate 110, and the bottom edge film area 240 is folded and wrapped on the side of the cell to be processed under the action of the positioning mechanism 164. When the opening and closing mechanism is pulled, the battery cell processing fixture can fold the battery cell coating film to achieve battery cell coating, that is, the side film area 220 is folded and coated on the battery cell to be processed under the action of the first side plate 120 and the second side plate 130, and the side film area 230 is folded and coated on the battery cell to be processed under the action of the first boss and the second boss. At the same time, the first positioning mechanism 122 on the first side plate 120 and the second positioning mechanism 132 on the second side plate 130 also clamp the coated battery cell. After the coating is completed, the gluing operation is performed at the positions of the first air avoidance mechanism 121 and the second air avoidance mechanism 131, thereby realizing the coating and gluing process to ensure the fixation of the battery cell after coating, which can improve the coating efficiency and the neatness of the edge of the battery cell after coating.

[0050] According to the battery processing fixture of the utility model, by setting a positioning mechanism for positioning the battery to be processed on the edge of the first side plate and the second side plate, the battery is limited during the battery cell assembly and coating process, so that the edges of the battery cell are neat after assembly and coating, and more accurate battery cell test data can be obtained on the pilot line, which can effectively reduce the complexity of the debugging process and speed up the battery mass production process. In addition, by setting a symmetrical first air avoidance mechanism and a second air avoidance mechanism for gluing on the first side plate and the second side plate, the gluing can be completed under the clamping of the battery processing fixture, simplifying the gluing process and improving the gluing efficiency and quality.

[0051] According to the utility model, when the battery cell coating film is to be processed, the side edges and the bottom edges are automatically folded and coated with the battery cell under the action of the first boss, the second boss and the positioning mechanism, thereby improving the battery cell processing efficiency.
