Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a clamp and a battery drying device having the same. Background Art

[0002] This section merely provides background information related to the present application and is not necessarily prior art.

[0003] Since the electrolyte in the battery is an organic substance that does not contain water molecules, the presence of water will reduce the electrochemical performance of the finished battery, causing the battery to swell, and even cause the battery to heat up and explode. Therefore, during the battery production process, it is a key link to ensure the quality of battery production to fully dry the battery to remove moisture from the battery so that it meets the battery's use requirements and avoid moisture from causing functional damage to the battery. However, the battery baking fixture in the current related technology can only meet the positioning of some batteries of specific sizes, and has poor compatibility. In addition, if the fixture needs to be changed for batteries of different sizes, the process is relatively complicated. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a clamp and a battery drying device having the same, so as to improve the versatility of the clamp. The specific technical solution is as follows:

[0005] An embodiment of the first aspect of the present application provides a clamp, comprising:

[0006] Box;

[0007] At least one first limiting rod is arranged in the box body in a manner that it can slide along the length direction of the box body and can be locked, and the first limiting rod extends along the width direction of the box body;

[0008] At least one second limiting rod is arranged in the box body in a manner that it can slide along the width direction of the box body and can be locked, and the second limiting rod extends along the length direction of the box body;

[0009] The locked first limiting rod, the locked second limiting rod, and the box body jointly define a placement space for placing the part to be positioned and having a positioning effect on the part to be positioned.

[0010] According to the clamp provided by the embodiment of the first aspect of the present application, since at least one first limit rod extending along the width direction of the box body and at least one second limit rod extending along the length direction of the box body are arranged in the box body, that is, the first limit rod and the second limit rod are arranged in a criss-cross manner in the box body, and the first limit rod can slide and be locked in the length direction of the box body, and the second limit rod can slide and be locked in the width direction of the box body. Therefore, by adjusting the position of the first limit rod and / or the second limit rod in the box body, the size of the placement space defined by the first limit rod, the second limit rod and the box body can be changed. In this way, the first limit rod and / or the second limit rod can be slid according to actual positioning requirements (such as the size of the part to be positioned, positioning in a lying state or an upright state, etc.), so that the first limit rod can contact one side of the current part to be positioned, and the second limit rod can contact the other side adjacent to the one side of the current part to be positioned, that is, adjusting the size of the placement space to achieve the positioning effect of the part to be positioned by placing the part to be positioned in the placement space. It can be seen that by using the clamp provided in the embodiment of the present application, the placement space can be adjusted according to the actual positioning requirements so that it is suitable for parts to be positioned with different sizes or positioning states, and the clamp has higher versatility.

[0011] In some embodiments of the present application, a first sliding cavity extending along the length direction of the box body is provided in the box body, and the clamp further includes a first fastener, the first fastener is confined in the first sliding cavity and can slide in the first sliding cavity, and the first fastener is connected to the first limiting rod and is configured to lock the position of the first limiting rod. By providing the first sliding cavity and the first fastener, the first limiting rod connected to the first fastener can slide more smoothly along the length direction of the box body and be locked in a desired position, so as to cooperate with the second limiting rod to limit the positioning member.

[0012] In some embodiments of the present application, the first limiting rod is provided with a first through hole, a first channel is provided on a side of the first sliding cavity close to the first limiting rod, and the first limiting rod is connected to the first fastener via a bolt passing through the first through hole and the first channel. By providing a first through hole for passing a bolt on the first limiting rod, and providing a first channel for passing the bolt on a side of the first sliding cavity close to the first limiting rod, the connection between the first limiting rod and the first fastener is achieved, and the convenience of assembly and disassembly of the bolt connection can be utilized to more easily achieve unlocking and locking of the first limiting rod.

[0013] In some embodiments of the present application, the clamp further includes a first mounting seat disposed in the box body, the first mounting seat being disposed along the length direction of the box body and having the first sliding cavity. By disposing the first mounting seat having the first sliding cavity in the box body along the length direction of the box body, it is easier to achieve installation and removal of the first limit rod in the box body. For example, the side of the first mounting seat facing away from the first channel can be connected to the bottom surface of the box body. In this case, the first limit rod is placed on the first mounting seat and the first through hole is aligned with the first channel. The first limit rod can be installed by screwing the bolt in the vertical direction (the height direction of the box body), which is more convenient to operate. Moreover, compared with other installation directions, it is easier to screw the bolt in the vertical direction.

[0014] In some embodiments of the present application, there are two first mounting seats, which are respectively arranged on both sides of the width direction of the box; the two ends of the first limiting rod are respectively placed on one of the first mounting seats and matched with the surface of the first mounting seat. By respectively arranging a first mounting seat on both sides of the width direction of the box, so that the two ends of the first limiting rod are respectively placed on one of the first mounting seats and matched with the surface of the first mounting seat, the installation stability of the first limiting rod can be improved.

[0015] In some embodiments of the present application, the box body is further provided with a second sliding cavity extending in the width direction of the box body, the clamp further includes a second fastener, the second fastener is confined in the second sliding cavity and can slide in the second sliding cavity, the second fastener is connected to the second limiting rod and is configured to lock the position of the second limiting rod. By providing the second sliding cavity and the second fastener, the second limiting rod connected to the second fastener can slide more smoothly in the width direction of the box body and be locked in a desired position, so as to cooperate with the first limiting rod to limit the positioning member.

[0016] In some embodiments of the present application, the second limiting rod is provided with a second through hole, a second channel is provided on a side of the second sliding cavity close to the second limiting rod, and the second limiting rod is connected to the second fastener via a bolt passing through the second through hole and the second channel. By providing a second through hole for passing the bolt on the second limiting rod, and providing a second channel for passing the bolt on a side of the second sliding cavity close to the second limiting rod, the connection between the second limiting rod and the second fastener is achieved, and the convenience of assembly and disassembly of the bolt connection can be utilized to more easily achieve unlocking and locking of the second limiting rod.

[0017] In some embodiments of the present application, the clamp further comprises a second mounting seat disposed in the box body, the second mounting seat being disposed along the width direction of the box body and having the second sliding cavity. By disposing the second mounting seat having the second sliding cavity in the box body along the width direction of the box body, it is easier to install and remove the second limit rod in the box body.

[0018] In some embodiments of the present application, the number of the second mounting seats is two, which are respectively arranged on both sides of the length direction of the box; the two ends of the second limiting rod are respectively placed on one of the second mounting seats and matched with the surface of the second mounting seat. By respectively arranging a second mounting seat on both sides of the length direction of the box, so that the two ends of the second limiting rod are respectively placed on one of the second mounting seats and matched with the surface of the second mounting seat, the installation stability of the second limiting rod can be improved.

[0019] In some embodiments of the present application, the box includes a bottom plate and side guard plates fixed to the periphery of the bottom plate. By providing a box including the bottom plate and the side guard plates, combined with the first limiting rod and the second limiting rod, it is possible to at least support the part to be positioned and limit the part to be positioned from moving in any direction perpendicular to the height of the box.

[0020] In some embodiments of the present application, the surfaces of the box, the first limiting rod, and the second limiting rod are all made of soft insulating materials. By setting the surfaces of the box, the first limiting rod, and the second limiting rod to be all made of soft insulating materials, on the one hand, if the part to be positioned is a charged component such as a battery, it is possible to avoid the potential safety hazard caused by electrical conduction of the charged part to be positioned during contact with the box, the first limiting rod, or the second limiting rod; on the other hand, the soft material is deformable under pressure, and when the part to be positioned is placed in the placement space defined by the box, the first limiting rod, and the second limiting rod, it is possible to reduce the damage to the part to be positioned caused by contact and friction with the box, the first limiting rod, or the second limiting rod.

[0021] The embodiment of the second aspect of the present application provides a battery drying device, which includes the clamp provided according to the embodiment of the first aspect of the present application, and the clamp is used to position the battery.

[0022] According to the battery drying device provided by the embodiment of the second aspect of the present application, since the box body of the clamp included therein is provided with at least one first limit rod extending along the width direction of the box body, and at least one second limit rod extending along the length direction of the box body, that is, the first limit rod and the second limit rod are crisscrossedly arranged in the box body, and the first limit rod can slide and be locked along the length direction of the box body, and the second limit rod can slide and be locked along the width direction of the box body. Therefore, by adjusting the position of the first limit rod and / or the second limit rod in the box body, the size of the placement space defined by the first limit rod, the second limit rod and the box body can be changed. In this way, the first limit rod and / or the second limit rod can be slid according to the actual positioning requirements (such as the size of the battery, positioning in a lying state or an upright state, etc.), so that the first limit rod can contact one side of the current battery, and the second limit rod can contact the other side adjacent to one side of the current battery, that is, the size of the placement space is adjusted to achieve the positioning of the battery when the battery is placed in the placement space. It can be seen that when the battery drying device provided in the embodiment of the present application is used to dry the battery, the clamp is more compatible with various types of batteries and positioning requirements.

[0045] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0046] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity. In a battery, there can be multiple battery cells, and multiple battery cells can be connected in series, in parallel, or in mixed connection. Mixed connection means that multiple battery cells are both connected in series and in parallel. Multiple battery cells can be directly connected in series, in parallel, or in mixed connection, and then the whole formed by the multiple battery cells is accommodated in a box; of course, the battery can also be a battery module formed by connecting multiple battery cells in series, in parallel, or in mixed connection, and then the multiple battery modules are connected in series, in parallel, or in mixed connection to form a whole, and are accommodated in a box. The battery may also include other structures. For example, the battery may also include a confluence component for realizing electrical connection between multiple battery cells. For example, the battery mentioned in the present application may include a battery module or a battery pack.

[0047] Each battery cell may be a secondary battery or a primary battery; it may also be a lithium-sulfur battery, a sodium-ion battery or a magnesium-ion battery, but is not limited thereto. In the present application, the battery cell may include a lithium-ion secondary battery, a lithium-ion primary battery, a lithium-sulfur battery, a sodium-lithium-ion battery, a sodium-ion battery or a magnesium-ion battery, etc., and the embodiments of the present application are not limited thereto. The battery cell may be cylindrical, flat, rectangular or in other shapes.

[0048] A battery cell is the smallest unit that makes up a battery. A battery cell includes an end cap, a housing, a battery cell assembly, and other functional components. A battery cell housing may contain one or more battery cell assemblies.

[0049] The end cap refers to a component that covers the opening of the shell to isolate the internal environment of the battery cell from the external environment. Without limitation, the shape of the end cap can be adapted to the shape of the shell to match the shell. Optionally, the end cap can be made of a material with a certain hardness and strength (such as aluminum alloy), so that the end cap is not easily deformed when squeezed and collided, so that the battery cell can have a higher structural strength and the safety performance can also be improved. Functional components such as electrode terminals can be provided on the end cap. The electrode terminal can be used to electrically connect to the battery cell assembly for outputting or inputting the electrical energy of the battery cell. In some embodiments, the end cap can also be provided with a pressure relief mechanism for releasing the internal pressure when the internal pressure or temperature of the battery cell reaches a threshold. The material of the end cap can also be a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application are not particularly limited to this. In some embodiments, an insulating member can also be provided on the inner side of the end cap, and the insulating member can be used to isolate the electrical connection components in the shell from the end cap to reduce the risk of short circuit. Exemplarily, the insulating member can be plastic, rubber, etc.

[0050] The shell is a component used to cooperate with the end cap to form the internal environment of the battery cell, wherein the formed internal environment can be used to accommodate the battery cell assembly, electrolyte and other components. The shell and the end cap can be independent components, and an opening can be set on the shell, and the internal environment of the battery cell is formed by covering the opening with the end cap at the opening. Without limitation, the end cap and the shell can also be integrated. Specifically, the end cap and the shell can form a common connection surface before other components are put into the shell, and when the interior of the shell needs to be encapsulated, the end cap is covered with the shell. The shell can be of various shapes and sizes, such as a rectangular parallelepiped, a cylindrical shape, a hexagonal prism, etc. Specifically, the shape of the shell can be determined according to the specific shape and size of the battery cell assembly. The material of the shell can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application do not impose any special restrictions on this.

[0051] The cell assembly is the part where the electrochemical reaction occurs in the battery cell. One or more cell assemblies may be contained in the shell. The cell assembly is mainly formed by winding or stacking the positive and negative electrode sheets, and a separator is usually provided between the positive and negative electrode sheets. The parts of the positive and negative electrode sheets with active materials constitute the main body of the cell assembly, and the parts of the positive and negative electrode sheets without active materials each constitute the tabs. The positive tab and the negative tab may be located together at one end of the main body or respectively at both ends of the main body. During the charge and discharge process of the battery, the positive active material and the negative active material react with the electrolyte, and the tabs connect the electrode terminals to form a current loop.

[0052] The battery cell can be cylindrical, flat, rectangular or other shapes, etc., and there is no special limitation on this in the embodiments of the present application. Battery cells are generally divided into three types according to the packaging method: cylindrical battery cells, square battery cells and soft-pack battery cells, and there is no limitation on this in the embodiments of the present application. The battery cells in the embodiments of the present application can be used in electrical devices such as vehicles, ships or aircraft, but are not limited to them.

[0053] Since the electrolyte in the battery is an organic substance that does not contain water molecules, the presence of water will reduce the electrochemical performance of the finished battery, causing the battery to swell, and even cause the battery to heat up and explode. Therefore, during the battery production process, it is a key link to ensure the quality of battery production to fully dry the battery to remove moisture from the battery so that it meets the battery's use requirements and avoid moisture from causing functional damage to the battery. However, the battery baking fixture in the current related technology can only meet the positioning of some batteries of specific sizes, and has poor compatibility. In addition, if the fixture needs to be changed for batteries of different sizes, the process is relatively complicated.

[0054] Based on the above considerations, in order to solve the problem of low versatility of the battery baking clamp, the inventor, after in-depth research, proposed a clamp, which is provided with a longitudinally adjustable transverse limit rod and a transversely adjustable longitudinal limit rod. By adjusting the positions of the transverse limit rod and the longitudinal limit rod, the size of the area defined by the transverse limit rod and the longitudinal limit rod for placing the parts to be positioned is changed, thereby improving the versatility of the clamp.

[0055] The positioning component disclosed in the embodiment of the present application can be used, but is not limited to, in the loading process of battery cells and the drying process of electrode assemblies in battery production. For example, when welding operations are performed on battery cells of different sizes during the packaging process, the battery cells can also be positioned using the clamp disclosed in the embodiment of the present application. Since the clamp disclosed in the embodiment of the present application is used to position different battery cells, the overall processing and production efficiency can be improved to a certain extent.

[0056] In view of this, if Figures 1 to 4As shown, an embodiment of the first aspect of the present application provides a clamp, comprising a box body 10, at least one first limiting rod 20, and at least one second limiting rod 30. The first limiting rod 20 is arranged in the box body 10 in a manner that it can slide along the length direction of the box body 10 and can be locked, and the first limiting rod 20 extends along the width direction of the box body 10; the second limiting rod 30 is arranged in the box body 10 in a manner that it can slide along the width direction of the box body 10 and can be locked, and the second limiting rod 30 extends along the length direction of the box body 10; the locked first limiting rod 20, the locked second limiting rod 30, and the box body 10 jointly define a placement space for placing a to-be-positioned member 1000 and having a positioning function for the to-be-positioned member 1000.

[0057] A fixture is a device used to fix an object to be processed during the production process so that it is in the correct position to receive the processing or treatment process. For example, in the present application, the fixture can specifically be a device for fixing a battery cell during the baking process of the battery cell.

[0058] The part to be positioned 1000 can be understood as an object to be processed that needs to be fixed in position during mechanical processing. For example, during the process of drying a battery cell, the battery cell needs to be positioned to facilitate subsequent processing operations. At this time, the battery cell can be used as the part to be positioned 1000.

[0059] The box body 10 can be understood as a basic component having a space for installing and accommodating other components or objects.

[0060] The first limiting rod 20 and the second limiting rod 30 can be understood as a long and narrow strip structure that is usually quite hard. The strip structure can be solid or hollow, and its material and specific cross-sectional shape are not particularly limited in the embodiment of the present application. The first limiting rod 20 is used to contact one side of the part to be positioned 1000 and prevent the part to be positioned 1000 from moving in the length direction of the box 10, and the second limiting rod 20 is used to contact the other side adjacent to one side of the part to be positioned 1000 and prevent the part to be positioned 1000 from moving in the width direction of the box 10.

[0061] According to the clamp provided by the embodiment of the first aspect of the present application, since the box body 10 is provided with at least one first limiting rod 20 extending along the width direction of the box body 10 and at least one second limiting rod 30 extending along the length direction of the box body 10, that is, the first limiting rod 20 and the second limiting rod 30 are crisscrossedly arranged in the box body 10, and the first limiting rod 20 can slide and be locked along the length direction of the box body 10, and the second limiting rod 30 can slide and be locked along the width direction of the box body 10, therefore, by adjusting the position of the first limiting rod 20 and / or the second limiting rod 30 in the box body 10, the position of the first limiting rod 20 can be changed. 0, the second limiting rod 30 and the size of the placement space defined by the box 10, so that the first limiting rod 20 and / or the second limiting rod 30 can be slid according to the actual positioning requirements (such as the size of the part to be positioned 1000, positioning in a lying state or an upright state, etc.), so that the first limiting rod 20 can contact one side of the current part to be positioned 1000, and the second limiting rod 30 can contact the other side adjacent to the one side of the current part to be positioned 1000, that is, the size of the placement space is adjusted to achieve the positioning of the part to be positioned 1000 by placing it in the placement space. It can be seen that the clamp provided by the embodiment of the present application can adjust the placement space according to the actual positioning requirements so that it is suitable for parts to be positioned of different sizes or positioning states, and the clamp has higher versatility.

[0062] For example, if the number of the first limit rod 20 and the number of the second limit rod 30 are both one, adjusting the positions of the first limit rod 20 and the second limit rod 30 can enable the first limit rod 20, the second limit rod 30 and the box body 10 to define one to four placement spaces; if the number of the first limit rod 20 and the second limit rod 30 are both multiple (two or more), in this case, every two first limit rods 20 with a spacing and every two second limit rods 30 with a spacing can also define a placement space for placing the part 1000 to be positioned and having a positioning function for the part 1000 to be positioned. In this way, when the number of parts 1000 to be positioned that need to be positioned is large, the clamp provided in the embodiment of the present application can simultaneously position multiple parts 1000 to be positioned, thereby improving the overall production efficiency.

[0063] In some embodiments of the present application, Figures 2 to 4 As shown, a first sliding cavity 501 extending along the length direction of the box body 10 is provided in the box body 10, and the clamp also includes a first fastener 40, which is confined in the first sliding cavity 501 and can slide in the first sliding cavity 501, and the first fastener 40 is connected to the first limiting rod 20 and is configured to lock the position of the first limiting rod 20.

[0064] The first sliding cavity 501 can be understood as a hollow structure having an outer contour shape and an interior for providing sliding space for other components. Its outer contour shape extends along the length direction of the box body 10, so that the sliding space inside it also extends along the length direction of the box body 10, thereby limiting other components in its sliding space to only slide along the length direction of the box body 10.

[0065] The first fastener 40 is a mechanical element that can mechanically fix or bond two or more elements together. It can be a standard part or a non-standard part, and there is no special limitation on this in the embodiments of the present application.

[0066] For example, the first fastener 40 may be a boat nut, which is a fixing tool with a hole in the center and threads on the inner side of the hole, and is often screwed together with a bolt or screw of a matching size to achieve a fastening effect. Figure 4 As shown, along the axial direction of the hole of the boat-shaped nut, the outside of the boat-shaped nut has a boat-shaped structure with a larger first end and a smaller second end, so it is called a boat-shaped nut, and the end face of the first end usually has a rough surface structure with wavy patterns or other concave-convex shapes. In this case, the outer contour shape of the first sliding cavity 501 can be designed to be compatible with the structure of the boat-shaped nut and suitable for having a certain gap with the end face of the first end of the boat-shaped nut. When the end face of the first end of the boat-shaped nut does not contact the inner wall of the first sliding cavity 501, the boat-shaped nut can slide freely in the first sliding cavity 501. When the end face of the first end of the boat-shaped nut contacts the inner wall of the first sliding cavity 501, since the end face of the first end of the boat-shaped nut is a rough surface structure, friction will be generated with the inner wall of the first sliding cavity 501. The tighter the end face of the first end of the boat-shaped nut contacts the inner wall of the first sliding cavity 501, the greater the static friction between the two. Under the action of the static friction between the two, the boat-shaped nut can be locked at any position in the first sliding cavity 501, thereby causing the first limit rod 20 connected to the boat-shaped nut to be locked at the corresponding position.

[0067] By providing the first sliding cavity 501 and the first fastener 40, the first limiting rod 20 connected to the first fastener 40 can slide more smoothly along the length direction of the box body 10 and be locked in a desired position, so as to cooperate with the second limiting rod 30 to limit the positioning member 1000.

[0068] In some embodiments of the present application, Figure 4 As shown, the first limiting rod 20 is provided with a first through hole 21, and a first channel 5011 is provided on a side of the first sliding cavity 501 close to the first limiting rod 20. The first limiting rod 20 is connected to the first fastener 40 by bolts passing through the first through hole 21 and the first channel 5011.

[0069] The first through hole 21 may be understood as a hole that penetrates the first limiting rod 20 along a direction perpendicular to the length of the first limiting rod 20 .

[0070] The first channel 5011 can be understood as an opening that passes through the first sliding cavity 501 to the outside.

[0071] A bolt is a cylindrical, threaded mechanical part that is matched with a nut. It usually consists of a head and a screw (a cylinder with external threads). The external threads of the bolt match the internal threads of the nut to fasten two parts with through holes or channels. The connection form through the combination of bolts and nuts is called bolt connection, which is a detachable connection.

[0072] For further example, if the first fastener 40 is a boat-shaped nut and the first end of the boat-shaped nut is close to the first channel 5011, then by rotating the bolt connected to the first limiting rod 20, so that the bolt is gradually rotated from the first end of the boat-shaped nut to the second end of the boat-shaped nut, the boat-shaped nut in the first sliding cavity 501 can be driven to gradually approach the first channel 5011 until the end surface of the first end of the boat-shaped nut conflicts with the inner wall of the first sliding cavity 501 close to the first limiting rod 20, so that the boat-shaped nut cannot move. static friction, thereby locking the first limit rod 20; on the contrary, rotating the bolt connected to the first limit rod 20 in the opposite direction can loosen the boat nut from the inner wall of the first sliding cavity 501 close to the first limit rod 20, thereby releasing the static friction between the end face of the first end of the boat nut and the inner wall of the first sliding cavity 501 close to the first limit rod 20, so that the boat nut can slide freely in the first sliding cavity 501, so as to adjust the position of the first limit rod 20 in the box body 10.

[0073] It can be seen that by providing a first through hole 21 for passing a bolt on the first limiting rod 20, and providing a first channel 5011 for passing the bolt on a side of the first sliding cavity 501 close to the first limiting rod 20, the connection between the first limiting rod 20 and the first fastener 40 is achieved. By utilizing the convenience of disassembly and assembly of the bolt connection, the unlocking and locking of the first limiting rod 20 can be more easily achieved.

[0074] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the clamp further includes a first mounting seat 51 disposed in the box body 10 . The first mounting seat 51 is disposed along the length direction of the box body 10 and has a first sliding cavity 501 .

[0075] The first mounting seat 51 can be understood as a component that connects two or more parts and supports some parts. It can be provided with a cavity, hole or groove for accommodating and installing the connecting parts.

[0076] By arranging the first mounting seat 51 having the first sliding cavity 501 in the box body 10 along the length direction of the box body 10, it is easier to install and remove the first limiting rod 20 in the box body 10. For example, the side of the first mounting seat 51 that is away from the first channel 5011 can be connected to the bottom surface of the box body 10. In this case, the first limiting rod 20 is placed on the first mounting seat 51 and the first through hole 21 is aligned with the first channel 5011. The first limiting rod 20 can be installed by screwing the bolts in the vertical direction (the height direction of the box body 10), which is more convenient to operate. In addition, compared with other installation directions, it is easier to screw the bolts in the vertical direction.

[0077] In some embodiments of the present application, there are two first mounting seats 51 , which are respectively arranged on both sides of the width direction of the box body 10 ; both ends of the first limiting rod 20 are respectively placed on a first mounting seat 51 and adapted to the surface of the first mounting seat 51 .

[0078] For example, if Figure 4 As shown, a first connecting portion 22 and a first abutting portion 23 may be provided at both ends of the first limiting rod 20 . The first connecting portion 22 is a portion of the first limiting rod 20 that contacts a surface of the first mounting seat 51 provided with the first channel 5011. Correspondingly, the surface of the first connecting portion 22 and the surface of the first mounting seat 51 provided with the first channel 5011 are both planes, so that the first limiting rod 20 can be more firmly connected to the first mounting seat 51; the first abutting portion 23 is a portion of the first limiting rod 20 that contacts an adjacent surface of a surface of the first mounting seat 51 provided with the first channel 5011. The first abutting portion 23 contacts and cooperates with an adjacent surface of a surface of the first mounting seat 51 provided with the first channel 5011, which can limit the movement of the first limiting rod 20 in the width direction of the box body 10 and provide a guiding effect for the first limiting rod 20 when the first limiting rod 20 slides along the length direction of the box body 10, so that the first limiting rod 20 can slide more smoothly on the first mounting seat 51 along the length direction of the box body 10.

[0079] It can be seen that by arranging a first mounting seat 51 on both sides of the box body 10 in the width direction, the two ends of the first limiting rod 20 are respectively placed on a first mounting seat 51 and adapted to the surface of the first mounting seat 51, which can improve the installation stability of the first limiting rod 20.

[0080] In some embodiments of the present application, a second sliding cavity extending along the width direction of the box body 10 is also provided in the box body 10, and the clamp also includes a second fastener, which is confined in the second sliding cavity and can slide in the second sliding cavity, and the second fastener is connected to the second limit rod 30 and is configured to lock the position of the second limit rod 30.

[0081] The second sliding cavity can be understood as a hollow structure with an outer contour shape and an interior for providing sliding space for other components. Its outer contour shape extends along the width direction of the box body 10, so that the sliding space inside it also extends along the width direction of the box body 10, thereby limiting other components in its sliding space to only slide along the width direction of the box body 10.

[0082] The second fastener is a mechanical element that can mechanically fix or bond two or more elements together. It can be a standard part or a non-standard part, and there is no special limitation on this in the embodiments of the present application.

[0083] For example, the second fastener can also be a boat nut. As described above for the first fastener 40, the boat nut is a fixing tool with a hole in the center and threads on the inside of the hole. It is often screwed together with bolts or screws of matching sizes to perform a fastening function. Along the axial direction of the hole of the boat nut, the outside of the boat nut has a boat-shaped structure with a larger first end and a smaller second end, so it is called a boat nut, and the end face of the first end usually has a rough surface structure with wavy patterns or other concave-convex shapes. In this case, the outer contour shape of the second sliding cavity can also be designed to be compatible with the structure of the boat-shaped nut and suitable for having a certain gap with the end face of the first end of the boat-shaped nut. When the end face of the first end of the boat-shaped nut does not contact the inner wall of the second sliding cavity, the boat-shaped nut can slide freely in the second sliding cavity. When the end face of the first end of the boat-shaped nut contacts the inner wall of the second sliding cavity, since the end face of the first end of the boat-shaped nut is a rough surface structure, friction will be generated with the inner wall of the second sliding cavity. The tighter the end face of the first end of the boat-shaped nut contacts the inner wall of the second sliding cavity, the greater the static friction between the two. Under the action of the static friction between the two, the boat-shaped nut can be locked at any position in the second sliding cavity, thereby causing the second limit rod 30 connected to the boat-shaped nut to be locked at the corresponding position.

[0084] By providing a second sliding cavity and a second fastener, the second limiting rod 30 connected to the second fastener can slide more smoothly along the width direction of the box body 10 and be locked in a desired position, so as to cooperate with the first limiting rod 20 to limit the positioning member 1000.

[0085] In some embodiments of the present application, the second limiting rod 30 is provided with a second through hole, and a second channel 5021 is provided on a side of the second sliding cavity close to the second limiting rod 30, and the second limiting rod 30 is connected to the second fastener by a bolt passing through the second through hole and the second channel 5021.

[0086] The second through hole may be understood as a hole that passes through the second limiting rod 30 along a direction perpendicular to the length of the second limiting rod 30 .

[0087] The second channel 5021 can be understood as an opening that passes through the second sliding cavity to the outside.

[0088] The bolts are similar to the description of the bolts connected to the first limiting rod 20 above, and are all cylindrical and threaded mechanical parts that are matched with nuts, and will not be described in detail here. The specifications of the bolts can be the same or different. For example, if the second fastener and the first fastener 40 are both boat-shaped nuts of the same specifications, then the bolts used to connect the first limiting rod 20 and the bolts used to connect the second limiting rod 30 can be bolts of the same specifications that are compatible with the boat-shaped nuts.

[0089] To give a further example, if the second fastener is a boat nut and the first end of the boat nut is close to the second channel 5021, then by rotating the bolt connected to the second limit rod 30, the bolt is gradually rotated from the first end of the boat nut to the second end of the boat nut, which can drive the boat nut in the second sliding cavity to gradually approach the second channel 5021 until the end face of the first end of the boat nut and the inner wall of the second sliding cavity close to the second limit rod 30 collide to generate a static friction force that makes the boat nut immovable, thereby locking the second limit rod 30; on the contrary, rotating the bolt connected to the second limit rod 30 in the opposite direction can loosen the boat nut from the inner wall of the second sliding cavity close to the second limit rod 30, thereby releasing the static friction between the end face of the first end of the boat nut and the inner wall of the second sliding cavity close to the second limit rod 30, so that the boat nut can slide freely in the second sliding cavity to facilitate the adjustment of the position of the second limit rod 30 in the box body 10.

[0090] It can be seen that by providing a second through hole for passing a bolt on the second limiting rod 30, and providing a second channel 5021 for passing the bolt on a side of the second sliding cavity close to the second limiting rod 30, the connection between the second limiting rod 30 and the second fastener is achieved. By utilizing the convenience of disassembly and assembly of the bolt connection, the unlocking and locking of the second limiting rod 30 can be achieved more easily.

[0091] In some embodiments of the present application, the clamp further includes a second mounting seat 52 disposed in the box body 10 , wherein the second mounting seat 52 is disposed along the width direction of the box body 10 and has a second sliding cavity.

[0092] The second mounting seat 52 can be understood as a component that connects two or more parts and supports some parts. It can be provided with a cavity, hole or groove for accommodating and installing the connecting parts.

[0093] By arranging the second mounting seat 52 having the second sliding cavity in the box body 10 along the width direction of the box body 10, it is easier to install and remove the second limiting rod 20 in the box body 10. For example, the side of the second mounting seat 52 that is away from the second channel 5021 can be connected to the bottom surface of the box body 10. In this case, the second limiting rod 30 is placed on the second mounting seat 52 and the second through hole is aligned with the second channel 5021. The second limiting rod 30 can be installed by screwing the bolt in the vertical direction (the height direction of the box body 10), which is more convenient to operate. In addition, compared with other installation directions, it is easier to screw the bolt in the vertical direction.

[0094] In some embodiments of the present application, there are two second mounting seats 52 , which are respectively arranged on both sides of the length direction of the box body 10 ; both ends of the second limiting rod 30 are respectively placed on a second mounting seat 52 and adapted to the surface of the second mounting seat 52 .

[0095] For example, as in the example of the first limiting rod 20 , the second limiting rod 30 may also be provided with a second connecting portion and a second abutting portion at both ends. The second connecting portion is a portion of the second limiting rod 30 that contacts a surface of the second mounting seat 52 provided with the second channel 5021. Correspondingly, the surface of the second connecting portion and the surface of the second mounting seat 52 provided with the second channel 5021 are both planes, so that the second limiting rod 30 can be more firmly connected to the second mounting seat 52; the second abutting portion is a portion of the second limiting rod 30 that contacts an adjacent surface of a surface of the second mounting seat 52 provided with the second channel 5021. The second abutting portion contacts and cooperates with an adjacent surface of a surface of the second mounting seat 52 provided with the second channel 5021, which can limit the movement of the second limiting rod 30 in the length direction of the box body 10 and provide a guiding effect for the second limiting rod 30 when the second limiting rod 30 slides in the width direction of the box body 10, so that the second limiting rod 30 can slide more smoothly on the second mounting seat 52 in the width direction of the box body 10.

[0096] It can be seen that by arranging a second mounting seat 52 on both sides of the box body 10 in the length direction, the two ends of the second limiting rod 30 are respectively placed on a second mounting seat 52 and adapted to the surface of the second mounting seat 52, so that the installation stability of the second limiting rod 30 can be improved.

[0097] In some embodiments of the present application, Figure 3 As shown, the box body 10 includes a bottom plate 11 and a side guard plate 12 fixed to the periphery of the bottom plate 11 .

[0098] The bottom plate 11 may be understood as the lower edge of the cross section of the box body 10 in the height direction of the box body 10 , and is suitable for providing supporting force for other components.

[0099] The side guard plate 12 can be understood as a plate structure used to prevent other components or objects placed in the box body 10 from tilting out in a direction perpendicular to the height of the box body 10 .

[0100] By providing a box body 10 including a bottom plate 11 and a side guard plate 12 , in combination with a first limiting rod 20 and a second limiting rod 30 , it is possible to at least support the part to be positioned 1000 and limit the part to be positioned 1000 from moving in any direction perpendicular to the height of the box body 10 .

[0101] In some embodiments of the present application, surfaces of the box body 10 , the first limiting rod 20 , and the second limiting rod 30 are all made of soft insulating material.

[0102] Soft insulating materials are materials that are non-conductive under the allowable voltage and can be deformed without losing performance, including but not limited to silicone, rubber, plastic, etc.

[0103] By setting the surfaces of the box body 10, the first limit rod 20, and the second limit rod 30 to be made of soft insulating material, on the one hand, if the part to be positioned 1000 is a charged component such as a battery, the safety hazard caused by electrical conduction during the contact between the charged part to be positioned 1000 and the box body 10, the first limit rod 20, or the second limit rod 30 can be avoided; on the other hand, the soft material can be deformed under pressure, and when the part to be positioned 1000 is placed in the placement space defined by the box body 10, the first limit rod 20, and the second limit rod 30, the damage to the part to be positioned 1000 caused by contact and friction with the box body 10, the first limit rod 20, or the second limit rod 30 can be reduced.

[0104] In some embodiments of the present application, Figures 1 to 4As shown, the clamp includes a box body 10, a plurality of first limiting rods 20, a plurality of second limiting rods 30, a boat-shaped nut, a first mounting seat 51, and a second mounting seat 52, wherein the first mounting seat 51 is arranged along the length direction of the box body 10 and has a first sliding cavity 501 extending along the length direction of the box body 10, a boat-shaped nut that can slide in the first sliding cavity 501 is restricted in the first sliding cavity 501, the first limiting rod 20 is connected to the boat-shaped nut in the first sliding cavity 501 by a bolt, and the boat-shaped nut in the first sliding cavity 501 is configured to lock the position of the first limiting rod 20, and the first limiting rod 20 is arranged along the width direction of the box body 10. Extension; the second mounting seat 52 is arranged along the width direction of the box body 10 and has a second sliding cavity extending along the width direction of the box body 10, and a boat nut that can slide in the second sliding cavity is restricted in the second sliding cavity, and the second limiting rod 30 is connected to the boat nut in the second sliding cavity by a bolt, and the boat nut in the second sliding cavity is configured to lock the position of the second limiting rod 30, and the second limiting rod 30 extends along the length direction of the box body 10; the locked first limiting rod 20, the locked second limiting rod 30, and the box body 10 jointly define a placement space for placing the part to be positioned 1000 and having a positioning effect on the part to be positioned 1000.

[0105] According to the clamp provided in this embodiment, since a plurality of first limiting rods 20 extending along the width direction of the box body 10 and a plurality of second limiting rods 30 extending along the length direction of the box body 10 are arranged in the box body 10, by adjusting the positions of the first limiting rods 20 and / or the second limiting rods 30 in the box body 10, the size of the placement space defined by the first limiting rods 20, the second limiting rods 30 and the box body 10 can be changed, so that the size of the placement space defined by the first limiting rods 20, the second limiting rods 30 and the box body 10 can be changed according to the actual positioning requirements (such as the size of the to-be-positioned part 1000, ... The placement space can be adjusted according to the situation of positioning, so that it can be suitable for parts to be positioned of different sizes or positioning states, and the clamp has higher versatility; moreover, every two first limiting rods 20 with a spacing and every two second limiting rods 30 with a spacing can also define a placement space for placing the part to be positioned 1000 and having a positioning effect on the part to be positioned 1000. In this way, when the number of parts to be positioned 1000 that need to be positioned is large, the clamp provided in the embodiment of the present application can simultaneously position multiple parts to be positioned 1000, which can improve the overall production efficiency.

[0106] The embodiment of the second aspect of the present application provides a battery drying device, which includes the clamp provided according to the embodiment of the first aspect of the present application, and the clamp is used to position the battery.

[0107] According to the battery drying device provided by the embodiment of the second aspect of the present application, Figures 1 to 4As shown, since the box body 10 of the clamp includes at least one first limiting rod 20 extending along the width direction of the box body 10 and at least one second limiting rod 30 extending along the length direction of the box body 10, that is, the first limiting rod 20 and the second limiting rod 30 are crisscrossedly arranged in the box body 10, and the first limiting rod 20 can slide and be locked along the length direction of the box body 10, and the second limiting rod 30 can slide and be locked along the width direction of the box body 10, therefore, by adjusting the position of the first limiting rod 20 and / or the second limiting rod 30 in the box body 10, The size of the placement space defined by the first limiting rod 20, the second limiting rod 30 and the box 10 can be changed. In this way, the first limiting rod 20 and / or the second limiting rod 30 can be slid according to the actual positioning requirements (such as the size of the battery, positioning in a lying state or an upright state, etc.), so that the first limiting rod 20 can contact one side of the current battery, and the second limiting rod 30 can contact the other side adjacent to one side of the current battery, that is, the size of the placement space is adjusted to achieve the positioning of the battery by placing the battery in the placement space. It can be seen that when the battery drying device provided in the embodiment of the present application is used to dry the battery, the clamp is more compatible with various types of batteries and positioning requirements.
