[0039] Example 1

[0040] See also Figures 1 to 4 As shown, the hot pressing and shaping device provided in the present application includes a pressing mechanism 101 and a shaping mechanism 102 .

[0041] The shaping mechanism 102 includes a first side pressure member 103 and a second side pressure member 104, and the first side pressure member 103 and the second side pressure member 104 are respectively opposite to the two curved sides of the battery cell 105; the pressing mechanism 101 is used to press down the flat surface of the battery cell 105; and the pressing mechanism 101 is provided with a first pushing block 109 and a second pushing block 110 to synchronously push the first side pressure member 103 and the second side pressure member 104 close to the corresponding curved sides when pressing down, thereby applying pressure to shape the curved sides.

[0042] Specifically, when the hot pressing shaping device is hot pressing and shaping the battery cell 105, the pressing mechanism 101 can move along the thickness direction of the battery cell 105 to apply pressure to the battery cell 105. Figure 3 and Figure 4 As shown, the thickness direction of the battery cell 105 is located in the vertical direction, and the pressing mechanism 101 applies pressure to shape the flat surface of the battery cell 105 (i.e., the large surface of the battery cell 105, which is formed by the side edges in the length direction and the side edges in the width direction of the battery cell 105) from above the battery cell 105 to make the flat surface of the battery cell 105 smoother.

[0043] The shaping mechanism 102 is used to apply pressure to the curved side edges of the battery cell 105 to flatten the curved side edges. Specifically, the first side pressure member 103 and the second side pressure member 104 of the shaping mechanism 102 are respectively arranged at the two curved side edges of the battery cell 105. When the pressing mechanism 101 applies pressure to the flat surface of the battery cell 105, the first pushing block 109 and the second pushing block 110 provided by the pressing mechanism 101 can respectively push the first side pressure member 103 and the second side pressure member 104, so that the first side pressure member 103 and the second side pressure member 104 synchronously apply pressure to the curved side edges of the battery cell 105, thereby achieving pressure shaping of the curved side edges.

[0044] The hot pressing and shaping device provided in the present application can simultaneously push the first side pressure member 103 and the second side pressure member 104 to apply pressure to the curved side of the battery cell 105 while the downward pressure mechanism 101 applies pressure and shapes the flat surface of the battery cell 105. There is no need to set up an additional driving mechanism to achieve pressure shaping of the curved side, which saves costs, has a simple structure, and is easy to maintain and use.

[0045] In an optional solution of this embodiment, the pressing mechanism 101 includes a pressing plate 108, the bottom surface of which is used to apply pressure to the flat surface of the battery cell 105 to make the flat surface of the battery cell 105 more flat. A first push block 109 and a second push block 110 are respectively connected to the two sides of the pressing plate 108. The first push block 109 is provided with a first push inclined surface 106 on the side close to the battery cell 105, and the second push block 110 is provided with a second push inclined surface 107 on the side close to the battery cell 105. Along the pressing direction of the pressing mechanism 101, the distance between the first push inclined surface 106 and the corresponding shaping surface of the curved side edge gradually increases, and the distance between the second push inclined surface 107 and the corresponding shaping surface of the curved side edge gradually increases.

[0046] In this embodiment, Figure 3 As shown, the first push block 109 is provided with a first push bevel 106, and the first push bevel 106 is tilted compared to the vertical direction. From top to bottom, the distance between the first push bevel 106 and the shaping surface corresponding to the curved side of the corresponding side (the shaping surface is located in the vertical direction) gradually increases. That is to say, the upper side of the first push bevel 106 (the end of the first push bevel 106 close to the lower pressure plate 108) is closer to the battery cell 105; the lower side of the first push bevel 106 (the end of the first push bevel 106 away from the lower pressure plate 108) is farther away from the battery cell 105. When the downward pressing mechanism 101 moves downward as a whole, the downward-moving first push bevel 106 can gradually push the first side pressure member 103 toward the battery cell 105, so that the first side pressure member 103 applies pressure to shape the curved side of the battery cell 105. In other words, the first push bevel 106 converts the downward pressing motion into a horizontal pushing motion.

[0047] Similarly, the second push block 110 is provided with a second push bevel 107, and the second push bevel 107 is tilted compared to the vertical direction. From top to bottom, the distance between the second push bevel 107 and the shaping surface corresponding to the curved side of the corresponding side (the shaping surface is located in the vertical direction) gradually increases. That is to say, the upper side of the second push bevel 107 (the end of the second push bevel 107 close to the lower pressure plate 108) is closer to the battery cell 105; the lower side of the second push bevel 107 (the end of the second push bevel 107 away from the lower pressure plate 108) is farther away from the battery cell 105. When the downward pressing mechanism 101 moves downward as a whole, the downward-moving second push bevel 107 can gradually push the second side pressure member 104 toward the battery cell 105, so that the second side pressure member 104 applies pressure to shape the curved side of the battery cell 105. In other words, the second push bevel 107 converts the downward pressing motion into a horizontal pushing motion.

[0048] In an optional solution of this embodiment, the first side pressure member 103 is provided with a first arcuate surface 111 or a first inclined surface, and the first arcuate surface 111 or the first inclined surface is opposite to the first pushing inclined surface 106 .

[0049] In this embodiment, Figure 3 As shown, a first plane is provided on the side of the first side pressure member 103 facing the first push block 109. The first plane is located in the vertical direction and is perpendicular to the flat surface of the battery cell 105. A first curved surface 111 or a first inclined surface is located above the first plane. When the first push block 109 contacts the first side pressure member 103, the first push inclined surface 106 can slide along the first curved surface 111 or the first inclined surface. The smooth surface of the first curved surface 111 can reduce friction, or the first inclined surface can match the first push inclined surface 106, thereby making it easier to push the first side pressure member 103 toward the battery cell 105. If the first side pressure member 103 is provided with a sharp-angle structure at this location, the first push inclined surface 106 can easily get stuck with the sharp-angle structure when pressed down, thereby affecting the function of the device.

[0050] Optionally, the second side pressure member 104 is provided with a second arcuate surface 112 , and the second arcuate surface 112 is opposite to the second push inclined surface 107 .

[0051] In this embodiment, Figure 3 As shown, a second plane is provided on the side of the second side pressure member 104 facing the second push block 110. The second plane is located in the vertical direction and is perpendicular to the flat surface of the battery cell 105. A second curved surface 112 or a second inclined surface is located above the second plane. When the second push block 110 contacts the second side pressure member 104, the second push inclined surface 107 can slide along the second curved surface 112 or the second inclined surface. The smooth surface of the second curved surface 112 can reduce friction, or the second inclined surface can match the second push inclined surface 107, making it easier to push the second side pressure member 104 toward the battery cell 105. If the second side pressure member 104 has a sharp angle structure at this location, the second push inclined surface 107 can easily get stuck with the sharp angle structure when pressed down, thereby affecting the function of the device.

[0052] In the optional solution of this embodiment, Figure 4 As shown, the first side pressure member 103 includes a first limiting bolt 113, a first pressure block 114 and a first pressure block 115; the first pressure block 114 is close to the first push block 109, and the first pressure block 115 is close to the battery cell 105. The first limiting bolt 113 connects the first pressure block 114 and the first pressure block 115, and can adjust the distance between the first pressure block 114 and the first pressure block 115.

[0053] In this embodiment, since the position of the first push block 109 remains unchanged, the horizontal distance that the first push block 109 pushes the first side pressure member 103 to move when it moves downward remains unchanged. When the hot pressing and shaping device performs hot pressing and shaping on battery cells 105 of different sizes, the distance between the first pressure-receiving block 114 and the first pressure-applying block 115 can be adjusted, thereby adjusting the end position of the compression of the first side pressure member 103, effectively preventing over-pressing and under-pressing.

[0054] For example, when hot-pressing a smaller battery cell 105, the first limiting bolt 113 is adjusted to increase the distance between the first pressure block 114 and the first pressure block 115, thereby bringing the first pressure block 115 closer to the battery cell 105. When the first push block 109 moves downward, the first pressure block 115 applies pressure to the curved side of the battery cell 105. When hot-pressing a larger battery cell 105, the reverse operation is sufficient.

[0055] Optionally, the second side pressure member 104 includes a second limiting bolt 116, a second pressure block 117, and a second pressure block 118; the second pressure block 117 is close to the second push block 110, and the second pressure block 118 is close to the battery cell 105. The second limiting bolt 116 connects the second pressure block 117 and the second pressure block 118, and can adjust the distance between the second pressure block 117 and the second pressure block 118. The structural principle of the second side pressure member 104 is the same as that of the first side pressure member 103 and will not be repeated here.

[0056] In an optional solution of this embodiment, the shaping mechanism 102 further includes a first guide assembly 119 and a second guide assembly 120. The first guide assembly 119 and the second guide assembly 120 are respectively installed on both sides of the battery cell 105, and the guiding directions of the first guide assembly 119 and the second guide assembly 120 are perpendicular to the shaping surface corresponding to the curved side.

[0057] Specifically, the first guide assembly 119 includes a first slide rail and a first slider slidably mounted on the first slide rail. The first slider is connected to the first side pressure member 103. When the first push block 109 pushes the first side pressure member 103 to move, the first guide assembly 119 can guide the movement of the first side pressure member 103. The second guide assembly 120 includes a second slide rail and a second slider slidably mounted on the second slide rail. The second slider is connected to the second side pressure member 104. When the second push block 110 pushes the second side pressure member 104 to move, the second guide assembly 120 can guide the movement of the second side pressure member 104.

[0058] In an optional solution of this embodiment, the shaping mechanism 102 further includes a first restoring member 121 and a second restoring member 122. The first restoring member 121 is connected to the first side pressure member 103 so that the first side pressure member 103 tends to move away from the battery cell 105. The second restoring member 122 is connected to the second side pressure member 104 so that the second side pressure member 104 tends to move away from the battery cell 105.

[0059] In this embodiment, both the first restoring member 121 and the second restoring member 122 are springs. After the hot pressing and shaping of the battery cell 105 is completed, the pressing mechanism 101 rises, the first restoring member 121 pushes the first side pressure member 103 to reset, and the second restoring member 122 pushes the second side pressure member 104 to reset, thereby releasing the battery cell 105 and allowing it to be moved to the next process step.

[0060] Example 2

[0061] The hot pressing shaping device in the second embodiment is an improvement on the basis of the above embodiment. The technical contents disclosed in the above embodiment will not be described repeatedly. The contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0062] See also Figure 4 As shown, in an optional solution of this embodiment, the hot pressing shaping device further includes a heating base 123, which is used to heat the battery cell to facilitate plasticization of the battery cell. The heating base 123 includes a heating table 124 and a bottom plate 125, and the heating table 124, the first side pressure member 103 and the second side pressure member 104 are all mounted on the bottom plate 125. The battery cell 105 is placed on the top surface of the heating table 124, and the pressure portion of the first side pressure member 103 and the pressure portion of the second side pressure member 104 are higher than the top surface of the heating table 124. When the first side pressure member 103 and the second side pressure member 104 translate, they will not rub against the top surface of the heating table 124.

[0063] In an optional solution of this embodiment, the top surface of the heating platform 124 is movably connected to a limit block 126 to limit the downward position of the pressing mechanism 101 and prevent the pressing mechanism from over-pressing the battery cell. The limit block 126 abuts the first side surface of the battery cell 105, which is arranged opposite the end surface of the battery cell 105 having the terminal tab.

[0064] In an optional solution of this embodiment, the heating platform 124 includes a heat-conducting block 127 and a heating device 128 . The heat-conducting block 127 is provided with a mounting hole, and the heating device 128 is installed in the mounting hole to heat the heat-conducting block 127 .
