DETAILED DESCRIPTION
[0041] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described here.
[0042] Figure 1 A schematic structural diagram of a feeding device provided by an exemplary embodiment of the present application at a first viewing angle. Figure 2 This is a schematic diagram of the structure of a feeding device provided by an exemplary embodiment of the present application at a second viewing angle. Figure 1 and Figure 2 As shown, the feeding device 100 provided in the embodiment of the present application may include a material box 110, and the material box 110 may be used to carry a plurality of material sheets 120, and the plurality of material sheets 120 are arranged along a preset direction (which can be understood as the height direction of the material box 110, i.e. Figure 1 The layers are distributed in layers (in the directions indicated by arrows A and B).
[0043] In one embodiment, the material sheet 120 may include a silicon sheet, a copper sheet, a pole piece in a battery, etc.
[0044] like Figure 1 and Figure 2 As shown, the loading device 100 may further include a blowing device 130, which may include at least two groups of blowing mechanisms 131, wherein some of the blowing mechanisms 131 may blow air to part of the sheet 120 at a first height position, and another part of the blowing mechanisms 131 may blow air to part of the sheet 120 at a second height position.
[0045] It should be noted that the first height position and the second height position respectively represent two different height positions in a preset direction, and different blowing mechanisms 131 can blow air to the material sheets 120 at different positions. In this way, the material sheets 120 at different height positions can be separated from each other, thereby improving the problem of poor blowing effect of the blowing device 130. The multi-layer material sheets 120 at different height positions can be completely separated, effectively ensuring the manufacturing quality of subsequent batteries.
[0046] In one embodiment, the number of the blowing mechanisms 131 may be two, three, four, or the like.
[0047] In one embodiment, the number of blowing mechanisms 131 is multiple groups (two groups or more), wherein a portion of the blowing mechanisms 131 is located at a first height position, and another portion of the blowing mechanisms 131 is located at a second height position, and the two portions of the blowing mechanisms 131 can respectively blow air to the sheet 120 at the first height position and the second height position.
[0048] In one embodiment, the number of blowing mechanisms 131 is multiple groups (two groups or more), and the multiple groups of blowing mechanisms 131 are arranged at the same height position, but one of the blowing mechanisms 131 blows toward a portion of the sheet 120 at the first height position, and another portion of the blowing mechanisms 131 blows toward a portion of the sheet 120 at the second height position.
[0049] like Figure 1 and Figure 2 As shown, the blowing device 130 may further include an annular track 132, which is arranged around the material box 110, and a slidable blowing mechanism 131 is mounted on the annular track 132. In other words, the blowing mechanism 131 can slide along the annular track 132 to achieve the function of moving around the material box 110. In the process of moving around the material box 110, the blowing mechanism 131 can blow 360° to the material sheet 120 in the material box 110. In this way, by continuously adjusting the blowing angle, the mutually adhered material sheets 120 can be separated at different positions, which is conducive to achieving the function of completely separating the multi-layer material sheets 120.
[0050] like Figure 1As shown, the circular track 132 is two layers, and the two layers of circular tracks 132 are parallelly distributed along a preset direction. It should be understood that the two layers of circular tracks 132 are equipped with a slidable blowing mechanism 131. Specifically, the blowing mechanism 131 equipped with the upper layer of the circular track 132 can perform 360° surrounding blowing on the material sheet 120 at the first height position, and the blowing mechanism 131 equipped with the lower layer of the circular track 132 can perform 360° surrounding blowing on the material sheet 120 at the second height position. In this way, it is more conducive to the separation of the material sheets 120 at different positions at the first height position and the second height position, thereby achieving the effect of completely separating the multi-layer material sheets 120.
[0051] It should be noted that, in actual applications, the blowing mechanism 131 on the upper circular track 132 can continuously blow air to part of the sheet 120 at the first height position, so that the upper sheet 120 can be in a floating state, while the blowing mechanism 131 on the lower circular track 132 can intermittently blow air to part of the sheet 120 at the second height position, so as to avoid the sheet 120 of the lower layer from sticking to the sheet 120 of the upper layer, thereby avoiding the multiple sheets 120 at different height positions from sticking to each other, which is conducive to the complete separation of the multiple sheets 120.
[0052] In one embodiment, the blowing mechanism 131 on the lower annular track 132 may blow air once every 30-50 mm, and each blowing time is 50 milliseconds.
[0053] Figure 3 A partial schematic diagram of a blowing mechanism and a circular track provided by an exemplary embodiment of the present application. Figure 3 As shown, the annular track 132 is provided with a first slide groove 1321, and the first slide groove 1321 extends along the extension direction of the annular track 132, that is, the first slide groove 1321 is an annular groove. Correspondingly, the blowing mechanism 131 may include a slider 1311, a connector 1312 and a blowing member 1313, the slider 1311 is slidably matched with the first slide groove 1321, the connector 1312 is connected to the slider 1311, and the blowing member 1313 is rotatably connected to the connector 1312.
[0054] Specifically, in actual application, the slider 1311 slides along the first slide groove 1321, which can drive the blowing member 1313 to move around the material box 110, so that the blowing member 1313 can blow air to the material sheet 120 at different directions. In addition, by rotating the connecting body 1312, the blowing angle of the blowing member 1313 can be adjusted, so that the blowing member 1313 can blow air to the material sheet 120 at different heights.
[0055] In one embodiment, the connector 1312 may be a universal shaft to adjust the blowing angle of the blowing member 1313 .
[0056] In one embodiment, the two opposite sides of the blowing member 1313 are connected with the aforementioned connecting bodies 1312 , and the two connecting bodies 1312 synchronously drive the blowing member 1313 to adjust the blowing angle, which can improve the stability of the blowing member 1313 during rotation.
[0057] like Figure 3 As shown, the blowing mechanism 131 may also include a first fixed body 1314 and a first fastener 1315. The first fixed body 1314 is arranged on the annular track 132. The first fixed body 1314 is provided with a first fixing hole (not shown in the figure). The first fastener 1315 cooperates with the first fixing hole and the first slide groove 1321, and the first fixed body 1314 can be fixed on the annular track 132.
[0058] In actual application, after the slider 1311 slides to the target position along the annular track 132, the aforementioned first fixing bodies 1314 are arranged on opposite sides of the slider 1311 along the extension direction of the annular track 132, and the two first fixing bodies 1314 respectively abut against opposite sides of the slider 1311. Since the two first fixing bodies 1314 can be fixed on the annular track 132 by the first fasteners 1315, the two first fixing bodies 1314 can limit the slider 1311 in the extension direction of the annular track 132. In this way, the slider 1311 can be kept at the current position, so that the blowing member 1313 can realize continuous and stable blowing operation at the current position.
[0059] In one embodiment, the first fastener 1315 may include a bolt, a screw, a pin, etc.
[0060] Figure 4 This is a schematic diagram of the structure of a material box provided by an exemplary embodiment of the present application. Figure 1 and Figure 4 As shown, the material box 110 may include a slide frame 140 and a plurality of limiting bodies 150 . The slide frame 140 is arranged around the material sheet 120 . The material sheet 120 is loaded on the inner side of the slide frame 140 . The plurality of limiting bodies 150 are connected to the slide frame 140 , and the plurality of limiting bodies 150 are distributed at intervals.
[0061] It should be noted that the plurality of limiting bodies 150 can be used to abut against different side walls of the sheet 120 to prevent the stacked sheets 120 from tilting and collapsing. In addition, compared with the solution of using an annular limiting column sleeved on the outside of the sheet 120, the contact area between the plurality of limiting bodies 150 and the sheet 120 in the embodiment of the present application is smaller, which can reduce the amount of material falling caused by the limiting bodies 150 scratching the sheet 120; and the plurality of limiting bodies 150 all abut against the side walls of the sheet 120, but not the top corners of the sheet 120, so the situation of material falling due to scratching the four top corners of the sheet 120 can be completely avoided.
[0062] In one embodiment, the limiting body 150 can be made of materials such as PE and Teflon, which can reduce damage to the sheet 120 .
[0063] In one embodiment, a soft rubber layer may be provided on the surface of the stopper 150 in contact with the material sheet 120, which can also reduce damage to the material sheet 120. Specifically, the material of the soft rubber layer may be rubber, foam cotton, etc.
[0064] In one embodiment, the limiting body 150 may include a rectangular column, a circular column, an elliptical column, etc.
[0065] Figure 5 This is a schematic diagram of the structure of a slide rail frame and a limiter provided by an exemplary embodiment of the present application. Figure 5 As shown, the slide rail frame 140 is provided with a protrusion 160, and the limiting body 150 is provided with a groove 170. The slide rail frame 140 and the limiting body 150 cooperate with each other through the protrusion 160 and the groove 170, which can facilitate the assembly and disassembly of the slide rail frame 140 and the limiting body 150 and improve the disassembly efficiency.
[0066] In one embodiment, the rail frame 140 is provided with the aforementioned groove 170 , and the limiting body 150 is provided with the aforementioned protrusion 160 , so that the rail frame 140 and the limiting body 150 can also cooperate with each other through the protrusion 160 and the groove 170 .
[0067] Figure 6 This is a schematic diagram of the structure of a slide rail frame, a limiting body, a second fixing body and a second fastener provided by an exemplary embodiment of the present application. Figure 6 As shown, the slide rail frame 140 is provided with a second slide groove 141, and the loading device 100 may also include a second fixed body 180 and a second fastener 190. The second fixed body 180 is arranged on the slide rail frame 140, and the second fixed body 180 is provided with a second fixing hole (not shown in the figure). The second fastener 190 cooperates with the second fixing hole and the second slide groove 141, and the second fixed body 180 can be fixed on the slide rail frame 140.
[0068] In practical applications, after the position-limiting body 150 is adjusted to the target position, the aforementioned second fixing bodies 180 are provided on opposite sides of the position-limiting body 150 along the extension direction of the slide rail frame 140, and the two second fixing bodies 180 respectively abut against opposite sides of the position-limiting body 150. Since the two second fixing bodies 180 can be fixed on the slide rail frame 140 by the second fasteners 190, the two second fixing bodies 180 can limit the position of the position-limiting body 150 along the extension direction of the slide rail frame 140. In this way, the position-limiting body 150 can be kept at the current position, so that the position-limiting body 150 can play a role in limiting the material sheet 120 stably for a long time.
[0069] In one embodiment, the number of the second sliding grooves 141 may be one, two, three, etc. When the number of the second sliding grooves 141 is multiple (two or more), the multiple second sliding grooves 141 are parallel to each other.
[0070] In one embodiment, the second fastener 190 may include a bolt, a screw, a pin, etc.
[0071] Figure 7 This is a schematic diagram of the structure of a base frame and a slide rail provided by an exemplary embodiment of the present application. Figure 7 As shown, the slide rail frame 140 may include a base frame 142, a slide rail 143 and a third fastener 200. The base frame 142 is provided with a third slide groove 1421. The slide rail 143 can be slidably engaged with the third slide groove 1421. The third fastener 200 can be detachably engaged with the slide rail 143 and the third slide groove 1421, and the slide rail 143 can be fixed on the base frame 142.
[0072] In actual applications, the position of the slide rail 143 is adjusted along the extension direction of the third slide groove 1421 according to needs. After the adjustment is completed, the third fastener 200 can be assembled on the slide rail 143 and the third slide groove 1421, so that the slide rail 143 and the base frame 142 remain relatively fixed. In this way, the slide rail 143 can be ensured to be in a stable state, which is conducive to ensuring that the limit body 150 assembled on the slide rail 143 is in a stable state.
[0073] It should be understood that if Figure 6 As shown, the aforementioned plurality of second slide grooves 141 are all disposed on the slide rail 143 , and the limiting body 150 is assembled on the slide rail 143 .
