[0005] By arranging an air outlet channel on at least one clamping member, the inlet end of the air outlet channel is connected to the air source, and the outlet end of the air outlet channel blows air toward the clamping space, the risk of the diaphragm folding can be reduced. The diaphragm that has been folded can also be smoothed by blowing air, thereby reducing the poor appearance of the battery and the risk of short circuit caused by direct contact between the positive and negative electrodes.

[0009] By setting the air outlet channel to include a first sub-channel, a connecting sub-channel, a second sub-channel and a third sub-channel that are connected in sequence, the air outlet channel is set to multiple sections according to the structure of the clamping part, which facilitates the circulation of gas in the air outlet channel and controls the final air outlet direction to blow obliquely toward the diaphragm.

[0029] By setting up a negative ion generator connected to an air source, the wind blown out by the negative ion generator enters the inlet end and the air inlet, so that the wind blown toward the diaphragm can also remove static electricity on the diaphragm, reduce the adhesion of particles on the diaphragm, and clean the diaphragm.

[0030] In some embodiments, the unloading mechanism further includes a negative ion generator installed on the base, one end of the negative ion generator is connected to the wind source, and the other end of the negative ion generator is connected to the inlet end.

[0046] The descriptions of directions such as "up", "down", "front", "back", "left" and "right" in this application are based on the directions shown in the figure and are only used to explain the relative positional relationship between the components in the posture shown in the figure.

[0047] Currently, market developments indicate that power batteries are becoming increasingly widely used. Power batteries are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in aerospace and other fields. As power battery applications continue to expand, market demand is also growing.

[0048] The unloading mechanism of the stacking machine is used to transport semi-finished battery cells. The semi-finished battery cells include positive electrode sheets, negative electrode sheets and a separator arranged between the positive electrode sheets and the negative electrode sheets. During transportation, the separator often folds.

[0049] After careful research, the applicant discovered that the positive and negative electrodes are stacked in an alternating pattern, while the separators are stacked in a Z-shaped pattern, with a separator positioned between each positive and negative electrode. The unloading mechanism of this application is designed to transport these semi-finished battery cells. However, when the robotic arm moves at a high speed, the separators are light and thin, and the separators at the ends may fold or bend due to wind resistance. This folding or bending can result in poor appearance. In severe cases, the folding of the separator can cause contact between the positive and negative electrodes, resulting in a short circuit in the battery cell.

[0050] The applicant's statistical research found that 10% of battery cells experience diaphragm folding during the lamination process, seriously affecting cell quality. Furthermore, when the robotic arm moves at speeds above 862.5 mm / s, adverse wind resistance causes over 95% of folding. Therefore, effectively reducing diaphragm folding has become a pressing issue.

[0051] To this end, the applicant provides a blanking mechanism.

[0052] Reference Figure 1 and Figure 2 According to some embodiments of the present application, the present application provides a blanking mechanism 100, including a base 1, a clamping member 3 and an air source. The number of the clamping members 3 is two, and the two clamping members 3 are both installed on the base 1. The two clamping members 3 are arranged relative to each other to define a clamping space 2. At least one clamping member 3 is provided with an air outlet channel 4, and the air outlet channel 4 has an inlet end 401 and an outlet end 402, and the outlet end 402 is arranged toward the clamping space 2; the air source is connected to the inlet end 401.

[0053] The base 1 is a component used to connect to an external robotic arm or drive mechanism. By driving the robotic arm or drive mechanism to move, the entire unloading mechanism 100 is moved, for example, to the loading position or unloading position. The clamping member 3 refers to a component used to clamp the semi-finished battery cell. There are two clamping members 3. The two clamping members 3 are arranged relative to each other to form a clamping space 2. The clamping space 2 is used to clamp the semi-finished battery cell. It should be noted that in the subsequent description, the battery cell also refers to the semi-finished battery cell clamped by the clamping member 3. The two meanings are the same. Of course, the two clamping members 3 can move relative to each other to adjust the distance between them, or in other words, to adjust the size of the clamping space 2, which is suitable for clamping semi-finished battery cells of different thicknesses. Specifically, the clamping member 3 can be slidably mounted on the base 1. At least one clamping member 3 is provided with an air outlet 4. At least one clamping member 3 means that either one of the two clamping members 3 is provided with an air outlet 4, or both clamping members 3 are provided with an air outlet 4. The air outlet channel 4 is a channel for wind to flow through. The inlet end 401 refers to the port for air inlet of the air outlet channel 4, and the outlet end 402 refers to the port for air outlet of the air outlet channel 4. The inlet end 401 of the air outlet channel 4 is connected to the wind source. The connection here can mean that the inlet end 401 is directly connected to the wind source; of course, it can also mean that there are other components between the wind source and the inlet end 401. The wind blown out of the wind source enters the air outlet channel 4 from the inlet end 401 after passing through other components, and then blows out from the outlet end 402. The outlet end 402 here is set toward the clamping space 2. In effect, it means that the wind is blown toward the clamping space 2. The setting here does not necessarily have to be directly opposite the clamping space 2, that is, the wind outlet direction is not necessarily perpendicular to the clamping space 2. It is also allowed to be at a certain angle to the clamping space 2, that is, the wind can be blown obliquely toward the clamping space 2. A semi-finished battery cell is arranged in the clamping space 2, and air is blown toward the diaphragm of the semi-finished battery cell through the outlet end 402. Specifically, the blowing direction is opposite to the folding direction of the diaphragm. It can also be said that the blowing direction is the same as the moving direction of the semi-finished battery cell. By applying a blowing force to the diaphragm, the risk of folding the diaphragm is reduced.

[0054] By arranging an air outlet channel 4 on at least one clamping member 3, the inlet end 401 of the air outlet channel 4 is connected to the air source, and the outlet end 402 of the air outlet channel 4 blows air toward the clamping space 2, the risk of the diaphragm folding can be reduced. For the diaphragm that has been folded, it can also be smoothed by blowing air, thereby reducing the poor appearance of the battery and the risk of short circuit caused by direct contact between the positive and negative electrodes.

[0055] Reference Figure 2In some embodiments, at least one clamping member 3 includes a connecting section 31 and a boss 32 connected to each other, the connecting section 31 is connected to the base 1, and the boss 32 is arranged on the side of the connecting section 31 facing the clamping space 2. The two clamping members 3 are arranged along the first direction, and the boss 32 includes a clamping surface 321 facing the clamping space 2 and air outlet side surfaces 322 arranged on opposite sides of the clamping surface 321 along the second direction. The air outlet side surfaces 322 are provided with an outlet end 402, and the first direction is perpendicular to the second direction.

[0056] It should be noted that the first direction in this application is as follows Figure 1 or Figure 2 As shown by the arrow Z, the second direction is Figure 1 or Figure 2 As shown by the arrow Y in the middle, the third direction is as follows Figure 1 or Figure 2 As shown by the arrow X in the figure. In the other figures, arrow X also indicates the third direction, arrow Y also indicates the second direction, and arrow Z also indicates the first direction. The connecting section 31 can be in the shape of an elongated strip, and one end of the connecting section 31 is connected to the base 1. Specifically, a threaded hole 311 can be provided at one end of the connecting section 31 for installation and fixation. The boss 32 is provided at the other end of the connecting section 31 and is facing the side of the clamping space 2. The boss 32 can be in the shape of a flat plate. The side of the boss 32 facing the clamping space 2 is the clamping surface 321, and the side of the boss 32 facing away from the clamping surface 321 is connected to the connecting section 31. The first direction here also refers to the vertical direction, which is also the direction in which the two clamping members 3 can move closer to or away from each other. The second direction also refers to the horizontal direction, which can specifically be the width direction of the connecting section 31. The two air outlet side surfaces 322 are respectively provided on the opposite sides of the clamping surface 321, and the outer edges are connected to the clamping surface 321. An outlet end 402 is provided on the air outlet side surface 322. It should be noted that the outlet end 402 in the present application is not arranged on the clamping surface 321 facing the clamping space 2, but is arranged on the two air outlet side surfaces 322. This is because we are facing the phenomenon of the diaphragm edge folding, so it is easier to reduce the risk of the diaphragm folding by setting the outlet end 402 on the air outlet side surface 322 and blowing the diaphragm obliquely to flatten the diaphragm that has already folded. At the same time, it can also reduce the damage to the diaphragm caused by excessive wind force. Because if the outlet end 402 is set on the clamping surface 321 facing the clamping space 2, the air is generally blown vertically towards the diaphragm, which is not only difficult to blow flat, but also the wind force may be too strong and cause the diaphragm to sag.

[0057] By arranging the outlet end 402 on the air outlet side surface 322 of the boss 32 and adopting an oblique blowing method, the risk of the diaphragm being folded can be reduced, and possible damage to the diaphragm can be reduced.

[0058] Reference Figure 3 and Figure 4 In some embodiments, the air outlet channel 4 includes a first sub-channel 41, a connecting sub-channel 42, a second sub-channel 43 and a third sub-channel 44 that are connected in sequence. The first sub-channel 41 is arranged on the connecting section 31, the second sub-channel 43 is arranged on the boss 32, and the first sub-channel 41 is provided with an inlet end 401 at an end away from the connecting sub-channel 42, and the third sub-channel 44 is provided with an outlet end 402 at an end away from the second sub-channel 43.

[0059] The air outlet channel 4 can be formed by multiple sub-channels connected in sequence. The first sub-channel 41 can be provided in the connecting section 31, and the second sub-channel 43 can be provided in the boss 32. The connecting sub-channel 42 serves to connect the first sub-channel 41 and the second sub-channel 43. The third sub-channel 44 is also provided on the boss 32. The end of the third sub-channel 44 away from the second sub-channel 43 passes through the air outlet side surface 322 to form the outlet end 402. The end of the first sub-channel 41 away from the connecting sub-channel 42 passes through the connecting section 31 to form the inlet end 401. With this design, air entering from the inlet end 401 can pass through the first sub-channel 41, the connecting sub-channel 42, the second sub-channel 43, and the third sub-channel 44 in sequence, and finally blown out of the outlet end 402 to the clamping space 2. It should be noted that the connection relationship here does not necessarily adopt an end-to-end connection method. For example, the connecting sub-channel 42 can be connected to the middle position of the second sub-channel 43, so that the wind entering from the connecting sub-channel 42 can blow to both sides of the second sub-channel 43 at the same time, which can reduce wind resistance and improve blowing efficiency.

[0060] By setting the air outlet channel 4 to include a first sub-channel 41, a connecting sub-channel 42, a second sub-channel 43 and a third sub-channel 44 connected in sequence, the air outlet channel 4 is set to multiple sections according to the structure of the clamping member 3, so as to facilitate the circulation of gas in the air outlet channel 4 and control the final air outlet direction to blow obliquely toward the diaphragm.

[0061] Reference Figure 3 and Figure 4 In some embodiments, the first sub-channel 41 and the second sub-channel 43 are both extended along the third direction, and the third sub-channel 44 is inclined from the second sub-channel 43 toward the clamping space 2, and the first direction, the second direction and the third direction are perpendicular to each other.

[0062] The aforementioned second direction is the width direction of the connecting section 31, and the third direction here is the length direction of the connecting section 31. The second sub-channel 43 and the first sub-channel 41 are both extended along the third direction, and the connecting sub-channel 42 can be vertically arranged along the first direction. Of course, the setting of this direction is only a specific embodiment of the present application, and is not limited to the scope of protection of the present application to only include this setting form. Those skilled in the art can set the appropriate direction according to actual needs. The third sub-channel 44 here is tilted from the second sub-channel 43 toward the clamping space 2, which means that the third sub-channel 44 is tilted relative to the clamping space 2, that is, the central axis of the third sub-channel 44 is tilted with the clamping space 2, or is neither parallel nor perpendicular to the first direction, so that the wind blown out from the outlet end 402 is blown obliquely toward the diaphragm. By setting the third sub-channel 44 to include the second sub-channel 43 horizontally arranged along the third direction and the third sub-channel 44 tilted, the horizontally arranged second sub-channel 43 can reduce wind resistance, and the tilted third sub-channel 44 can make the wind blown out from the outlet end 402 blow obliquely toward the clamping space 2 or the diaphragm.

[0063] Reference Figure 3 or Figure 4 In some embodiments, there are multiple third sub-channels 44 , and the multiple third sub-channels 44 are arranged at intervals along the third direction.

[0064] In order to achieve blowing to various positions of the diaphragm and cover the range of the diaphragm as much as possible, multiple third sub-channels 44 can be set. The multiple third sub-channels 44 are arranged along the extension direction of the second sub-channel 43, that is, they are discharged along the third direction. It can also be inferred from this embodiment that since there are multiple second sub-channels 43, each second sub-channel 43 corresponds to an outlet port 402, so the number of outlet ports 402 is actually multiple. It should also be noted that the third sub-channels 44 here are not necessarily arranged evenly, but can also be arranged unevenly, because folding generally occurs at the edge or top corner of the diaphragm, that is, the third sub-channels 44 can be arranged more densely at the position toward the edge of the diaphragm and sparsely at the middle position of the diaphragm. Corresponding to the structure of the clamping member 3, the third sub-channels 44 can be arranged more densely at the two ends of the second sub-channel 43, that is, the distance between the third sub-channels 44 is smaller, and the third sub-channels 44 can be arranged more sparsely at the middle position of the second sub-channel 43, that is, the distance between the third sub-channels 44 is larger.

[0065] By providing a plurality of third sub-channels 44 and correspondingly providing a plurality of outlet ports 402 , air can be blown from a plurality of positions of the diaphragm, thereby increasing the area of the diaphragm for blowing and smoothing.

[0066] Reference Figure 2 and Figure 3In some embodiments, the second sub-channel 43 penetrates the boss 32 along the third direction to form two first openings 441 , and the boss 32 is movably connected to a first blocking member 5 corresponding to each first opening 441 for opening or closing the first opening 441 .

[0067] In actual use, due to the presence of the outlet port 402, especially when there are multiple outlet ports 402, although the outlet port 402 is tilted and can reduce the entry of dust to a certain extent, after a long period of use, dust will inevitably enter the air outlet channel 4 and cause blockage. Once the air outlet channel 4 is blocked, the blowing effect will be greatly reduced, affecting the product yield. To this end, when setting the second sub-channel 43, the second sub-channel 43 is set to pass through the boss 32, so that a first opening 441 is formed at each end of the second sub-channel 43, that is, there are two first openings 441 in total. At intervals or when the channel is blocked, a large air flow and fast blowing can be carried out from one of the first openings 441 to the second sub-channel 43, so that dust can be quickly blown out from the other first opening 441, thereby playing a cleaning role. Of course, when cleaning is not required, in order to reduce the risk of dust entering the air outlet channel 4 from the first opening 441, a first blocking member 5 can be provided on the first opening 441. The first blocking member 5 can be detachably mounted on the first opening 441. When cleaning is required, the first blocking member 5 can be removed and the second sub-channel 43 can be blown to clean. When cleaning is not required, the first blocking member 5 can be used to close the first opening 441 to reduce the risk of dust entering from the first opening 441. The first blocking member 5 here can be a threaded member or a pin. In addition, it should be noted that when two first openings 441 are provided, the second sub-channel 43 is equivalent to a through hole during processing, and the processing difficulty is relatively low. If the first opening 441 is not provided, the second sub-channel 43 is an internal hole in the boss 32, and the processing difficulty will be greatly increased.

[0068] By setting an outlet hole section through the boss 32 to form a first opening 441, the air outlet channel 4 can be cleaned through the first opening 441 to remove internal dust and keep the channel unobstructed. At the same time, setting a first movably connected blocking member 5 can reduce the risk of dust entering the air outlet channel 4 from the first opening 441.

[0069] Reference Figure 2 and Figure 3 In some embodiments, the boss 32 is provided with a cleaning channel 11, one end of the cleaning channel 11 passes through the clamping surface 321 to form a second opening 3211, and the other end of the cleaning channel 11 is connected to the second sub-channel 43; and / or, the boss 32 is movably connected to the position corresponding to the second opening 3211 with a second blocking member 6 for opening or closing the second opening 3211.

[0070] Specifically, one end of the cleaning channel 11 is connected to the second sub-channel 43, and the other end of the cleaning channel 11 passes through the clamping surface 321 to form a second opening 3211. The function of the cleaning channel 11 is to allow air to enter through the second opening 3211 for cleaning. The air can be blown out from the outlet end 402, the inlet end 401, or the two first openings 441, and at the same time, it can take away the dust in the air channel 4. As for the connection position between the cleaning channel 11 and the second sub-channel 43, in a specific embodiment, it can be connected to the middle position of the second sub-channel 43. In this way, after the air enters the second sub-channel 43, it can be blown to both ends at the same time, reducing the flow path in the second sub-channel 43, thereby reducing wind resistance and improving cleaning efficiency. Of course, in another more specific embodiment, the cleaning channel 11 can be coaxially arranged with the connecting sub-channel 42, and the cross-sectional areas of the two are the same or similar, so that the wind coming in from the cleaning channel 11 can directly enter the connecting sub-channel 42 through a very small distance of the second sub-channel 43, and then enter the first sub-channel 41 through the connecting sub-channel 42, and finally blow out from the inlet end 401, which can clean the connecting sub-channel 42 and the first sub-channel 41, and because the path of circulation in the second sub-channel 43 is short, the reduction in wind force is relatively small, which can play a better cleaning role. In addition, the cleaning channel 11 can be coaxially arranged with the connecting sub-channel 42, and it can also facilitate the processing and forming of the connecting sub-channel 42. The principle of the second blocking member 6 is similar to that of the first blocking member 5. Both are used to close the second opening 3211 when cleaning is not required to prevent dust from entering the cleaning channel 11 from the second opening 3211 and then entering the air outlet channel 4. The second blocking member 6 here can be a threaded member or a pin. In addition, the applicant would like to explain that when the clamping member 3 does not clamp the battery cell, a large flow rate and high wind speed gas can also be introduced into the air outlet channel 4 from the inlet end 401 to clean the air outlet channel 4.

[0071] By setting up the cleaning channel 11, the dust in the air outlet channel 4 can be cleaned and the air outlet channel 4 can be kept unobstructed. At the same time, setting up the second blocking member 6 at the second opening 3211 can reduce the risk of dust entering the air outlet channel 4 from the second opening 3211.

[0072] Reference Figure 1 and Figure 5 In some embodiments, the unloading mechanism 100 further includes a blowing assembly, which includes a blowing rod 7, which is provided with an air inlet 71, an air duct 72 connected to the air inlet 71, and an air outlet 73 connected to the air duct 72, the air inlet 71 is connected to the air source, and the air outlet 73 is arranged toward the clamping space 2.

[0073] The blowing rod 7 is in the shape of a rod, and an air duct 72 is provided inside the blowing rod 7 for air flow to pass through. The air inlet 71 and the air outlet 73 are both connected to the air duct 72. The gas enters the air duct 72 from the air inlet 71 and is then blown out from the air outlet 73. The air outlet 73 is arranged toward the clamping space 2, which means that the air outlet 73 blows toward the clamping space 2, that is, toward the diaphragm. The air inlet 71 here can be arranged in the middle of the air duct 72, so that the gas coming in from the air inlet 71 can be blown toward both sides of the air duct 72, which can not only improve the blowing efficiency but also reduce the wind resistance. Similar to the outlet end 402 mentioned above, the air outlet 73 can be arranged at an angle, that is, it can be arranged at an angle relative to the clamping space 2 or the diaphragm, so that the inclined wind is blown toward the diaphragm, which is more conducive to reducing the risk of the diaphragm folding. It should be noted that the blowing assembly here can be used alone and can also play the role of smoothing the diaphragm. The clamping member 3 can also be provided with an air outlet channel 4 to play a further auxiliary role.

[0074] By providing a blowing rod 7 to blow air to smooth the diaphragm, the risk of the diaphragm folding can be further reduced.

[0075] Reference Figure 1 and Figure 5 In some embodiments, the blowing rod 7 is extended along the second direction, and there are multiple air outlets 73, which are spaced apart on the blowing rod 7 along the second direction.

[0076] The second direction is the width direction of the connecting section 31, which is also the length direction of the blowing rod 7. The number of air outlets 73 is set to be multiple, and multiple air outlets 73 can be arranged at intervals on the blowing rod 7, and each air outlet 73 is connected to the air duct 72, so that the diaphragm can be blown from multiple positions in the second direction. The multiple air outlets 73 here may not be evenly arranged, and in particular, they can be arranged at positions corresponding to the edges of the diaphragm to arrange the air outlets 73 more densely, reducing the risk of the diaphragm edge folding or cornering. The air outlets 73 at both ends of the blowing rod 7 can be arranged more densely, and the air outlets 73 in the middle of the blowing rod 7 can be arranged more sparsely. In some specific embodiments, the air duct 72 passes through the blowing rod 7 along the second direction to form two third openings, and each third opening is detachably provided with a third blocking member 74, where the third blocking member 74 can be a threaded member or a pin. The purpose of setting two third openings is similar to that of setting the first opening 441 and the second opening 3211, both of which serve a cleaning function. High-speed airflow can be introduced from one of the third openings and out from the other opening to clean the dust in the air duct 72. When cleaning is not required, the third blocking member 74 is used to block the air duct 72 to prevent dust from entering the air duct 72 from the third opening.

[0077] By providing a plurality of air outlets 73 , which are spaced apart along the length direction of the blowing rod 7 , air can be blown from multiple positions of the diaphragm, thereby increasing the blowing and smoothing area of the diaphragm by the blowing rod 7 .

[0078] Reference Figure 1 In some embodiments, the blowing assembly further includes two mounting seats 8 arranged opposite to each other, both mounting seats 8 are mounted on the base 1, each mounting seat 8 is provided with an axial hole, and both ends of the blowing rod 7 are rotatably mounted on the two axial holes.

[0079] The mounting base 8 is a base body, and an axial hole is provided in the middle of the mounting base 8. The two mounting bases 8 are arranged opposite to each other, and the central axes of the two axial holes coincide with each other. The two ends of the blowing rod 7 are respectively installed in the two axial holes. The blowing rod 7 can be rotated in the axial hole, thereby adjusting the air outlet direction of the air outlet 73 to achieve inclined blowing. The air outlet direction of the air outlet 73 can be adaptively adjusted according to the type of semi-finished battery cell or the position of the diaphragm to adjust to the optimal blowing angle. In another specific embodiment, the mounting base 8 can be hinged to the base 1, and the air outlet 73 is driven to rotate together by the rotation of the mounting base 8 relative to the base 1, which can also play a role in adjusting the air outlet direction of the air outlet 73.

[0080] By arranging the blowing rod 7 to be rotatably mounted on the base 1 , the blowing direction of the air outlet 73 can be adjusted, and a better blowing angle can be selected to smooth the diaphragm.

[0081] Reference Figure 1 and Figure 2 In some embodiments, the two clamping members 3 are an upper clamping member 301 and a lower clamping member 302 , respectively. The blowing rod 7 is arranged on the side of the upper clamping member 301 away from the lower clamping member 302 , and the lower clamping member 302 is provided with an air outlet channel 4 .

[0082] The air outlet channel 4 can be set on both the upper clamping member 301 and the lower clamping member 302. The upper clamping member 301 is set above the lower clamping member 302. The up and down directions refer to the up and down directions of the vertical direction. Figure 1 Indicated by the middle arrow Z. In this embodiment, an air outlet channel 4 is provided on the lower clamping member 302 to blow air from the bottom of the diaphragm, which can smooth the diaphragm from the bottom of the diaphragm. A blowing rod 7 is provided on the upper clamping member 301 to blow air from the top of the diaphragm, which can smooth the diaphragm from the top of the diaphragm. In this way, both the top and bottom of the diaphragm, that is, both sides of the diaphragm are blown and smoothed, which is beneficial to improving product yield.

[0083] By arranging the air outlet channel 4 on the lower clamping member 302 and the blowing rod 7 on the upper clamping member 301, the diaphragm can be blown and smoothed from both sides of the diaphragm, thereby improving the product yield.

[0084] Reference Figure 1 In some embodiments, the unloading mechanism 100 further includes a negative ion generator 9 mounted on the base 1 , one end of the negative ion generator 9 is connected to the wind source, and the other end of the negative ion generator 9 is connected to the inlet end 401 and the air inlet 71 respectively.

[0085] The negative ion generator 9 can be made of components that can be purchased on the market. Specifically, the negative ion generator 9 includes a central through pipe. During production, an insulating silicone sleeve is embedded in the central through pipe. The insulating silicone sleeve is used to prevent leakage and ensure the air tightness of the negative ion generator 9. Then, holes are punched in the silicone sleeve to insert carbon bristles. When in use, 220V electricity can be applied to the tip of the carbon bristles to generate negative high voltage ionized air to produce negative ions. The wind blown out by the wind source will enter the inlet end 401 of the clamping member 3 and the air inlet 71 of the blowing rod 7 after passing through the negative ion generator 9. The blowing negative ion wind can not only smooth the diaphragm, but also remove static electricity on the diaphragm, reduce the adhesion of particles on the diaphragm, and clean the diaphragm.

[0086] By setting the negative ion generator 9 to be connected to the air source, the wind blown out by the negative ion generator 9 enters the inlet end 401 and the air inlet 71, so that the wind blown toward the diaphragm can also remove static electricity on the diaphragm, reduce the adhesion of particles on the diaphragm, and clean the diaphragm.

[0087] Reference Figure 1 In some embodiments, the upper clamping member 301 includes a plurality of upper clamping rods 303, which are arranged at intervals along the second direction; the lower clamping member 302 includes a plurality of lower clamping rods 304, which are arranged at intervals along the second direction; and at least one lower clamping rod 304 is provided with an air outlet channel 4.

[0088] The upper clamping member 301 includes a plurality of upper clamping rods 303, which are spaced apart in the second direction. Providing a plurality of upper clamping rods 303 and a plurality of lower clamping rods 304 is more conducive to clamping the battery cells. At the same time, an air outlet channel 4 can be provided on the lower clamping rods 304 corresponding to the position where the diaphragm needs to be blown and smoothed, thereby blowing and smoothing the diaphragm. The air outlet channel 4 can be provided on one of the lower clamping rods 304, or on two of the lower clamping rods 304. Of course, the air outlet channel 4 can also be provided on all of the lower clamping rods 304. The air outlet channel 4 can also be provided on the upper clamping rod 303. In a specific embodiment, the number of upper clamping rods 303 and lower clamping rods 304 are both three.

[0089] By providing multiple upper clamping rods 303 and lower clamping rods 304, the battery cell can be clamped at various positions, which is conducive to stable clamping. In addition, an air outlet channel 4 can be provided on the lower clamping rod 304 to facilitate blowing air from various positions of the diaphragm, thereby improving the smoothing effect.

[0090] Reference Figure 1In some embodiments, the unloading mechanism 100 further includes a negative ion generator 9 mounted on the base 1 , one end of the negative ion generator 9 is connected to the wind source, and the other end of the negative ion generator 9 is connected to the inlet end 401 .

[0091] The negative ion generator 9 can use components that can be purchased on the market. The wind blown out by the wind source will enter the inlet end 401 of the clamping member 3 after passing through the negative ion generator 9. The blowing out negative ion wind can not only smooth the diaphragm, but also remove the static electricity on the diaphragm, reduce the adhesion of particles on the diaphragm, and clean the diaphragm.

[0092] By setting the negative ion generator 9 to be connected to the air source, the wind blown out by the negative ion generator 9 enters the inlet end 401, so that the wind blown toward the diaphragm can also remove static electricity on the diaphragm, reduce the adhesion of particles on the diaphragm, and clean the diaphragm.

[0093] Reference Figure 1 In some embodiments, the unloading mechanism 100 further includes an air filter 10 , which is connected to the negative ion generator 9 and the wind source.

[0094] The air filter 10 is used to remove dust particles in the air, so that the air entering the negative ion generator 9 and the air outlet channel 4 is clean. Specifically, the air source and the air filter 10, the air filter 10 and the negative ion generator 9, and the negative ion generator 9 and the clamping member 3 or the blowing rod 7 can be connected through air pipes (omitted in the figure).

[0095] By providing the air filter 10 , the air entering the air outlet channel 4 can be purified, the cleanliness of the air can be improved, and the risk of dust in the air entering the air outlet channel 4 and causing blockage can be reduced.

[0096] Reference Figure 1 In some embodiments, at least one clamping member 3 is slidably mounted on the base 1 so that the two clamping members 3 can move closer to or farther away from each other.

[0097] One of the clamping members 3 can be mounted on the base 1 by sliding along the first direction, or both clamping members 3 can be mounted on the base 1 by sliding along the first direction. The thickness of the clamping space 2 in the first direction can be adjusted by sliding the clamping members 3, thereby being suitable for clamping battery cells of different thicknesses. Specifically, when the two clamping members 3 are brought closer together, the thickness of the clamping space 2 decreases, allowing for clamping thinner battery cells; when the two clamping members 3 are moved away from each other, the thickness of the clamping space 2 increases, allowing for clamping thicker battery cells.

[0098] By arranging the clamping member 3 to be slidably mounted on the base 1 , the size of the clamping space 2 can be adjusted, so as to be suitable for clamping battery cells of different specifications.
