Description

Technical Field

[0001] The present application relates to the field of vapor deposition technology, and in particular to a limiting mechanism, a feeding device and a battery manufacturing system. Background Art

[0002] The statements herein merely provide background information related to the present application and do not necessarily constitute prior art.

[0003] In the process of preparing the electrode, a variety of powders and liquids need to be put into a mixer, and after stirring by the mixer, a paste-like slurry with a certain viscosity is obtained. The slurry is then coated on the current collector, and the electrode is formed after drying.

[0004] In the related art, the method of feeding powder into the mixer is to adopt open manual feeding, that is, the cover body of the feeding port of the mixer is opened by a cylinder, and then the powder is fed from the feeding port, but the reliability of opening the cover is low. Utility Model Content

[0005] In view of the problem, the present application provides a limiting mechanism, a feeding device and a battery manufacturing system, which can alleviate the problem of low reliability of opening the cover of the feeding device.

[0006] In a first aspect, the present application provides a limiting mechanism for a feeding device, the feeding device comprising a feeding body having a feeding port and a cover body covering the feeding port, the limiting mechanism comprising:

[0007] A fixing assembly, used for fixing on the feeding body; and

[0008] A movable member is movably disposed on the fixed assembly, and the movable member includes a limiting position for supporting and limiting the cover body along a first direction when the cover body opens the feeding port;

[0009] Wherein, the fixing component includes a support and limiting member. When the movable member is in a limiting position, the support and limiting member can support the movable member along a first direction and limit the movable member along a second direction; the first direction intersects with the second direction.

[0010] The above-mentioned limiting mechanism, by arranging a fixed component and a movable part, can enable the movable part to move to the limited position relative to the fixed component when the cover body is opened. Since the supporting limiting part of the fixed component can support the movable part along a first direction when the movable part is in the limited position and limit it in a second direction intersecting with the first direction, the possibility of the movable part slipping, deflecting and other abnormalities in the second direction is reduced, so that the movable part can reliably support the limited cover body along the first direction, thereby improving the reliability of opening the cover.

[0011] In some embodiments, the support and limiting member includes a first support surface and a first limiting portion provided on the first support surface, and the movable member has a support matching portion;

[0012] When the movable member is in the limiting position, the first supporting surface can support the supporting matching portion along the first direction, and the first limiting portion cooperates with the supporting matching portion to limit along the second direction.

[0013] By providing the first support surface to support the support matching portion of the movable member, the stability of the support can be improved, and by the first limiting portion provided on the first support surface cooperating with the support matching portion, stable limiting in the second direction can be achieved. In addition, since the first limiting portion is provided on the first support surface, the supporting and limiting effects on the support matching portion of the movable member are more concentrated, thereby making the supporting and limiting effects more reliable.

[0014] In some embodiments, the supporting matching portion has a first matching portion, and when the movable member is in the limiting position, the first limiting portion cooperates with the first matching portion along the circumferential direction to limit along the second direction.

[0015] By setting the supporting matching part of the movable part to have a first matching part, and making the first limiting part of the supporting limiting part match circumferentially along the first matching part to limit along the second direction, the abnormality of the movable part being offset relative to the fixed component in any direction other than the first direction at the limiting position can be reduced, thereby improving the limiting reliability of the movable part at the limiting position.

[0016] In some embodiments, one of the first limiting portion and the first matching portion includes a limiting hole, and the other includes a limiting protrusion matching with the limiting hole.

[0017] The circumferential limiting is achieved by providing the limiting hole and cooperating with the limiting protrusion, so that the matching mode between the first limiting portion and the first matching portion is simple, thereby making it easier to operate the limiting operation of the movable part relative to the fixed component.

[0018] In some embodiments, the movable member further includes a movable rod extending along a first direction, and the supporting matching portion is connected to the movable rod and protrudes from the movable rod along a second direction.

[0019] By providing a movable rod extending in the first direction, the supporting matching portion connected thereto can directly reach the limit position supported on the supporting limit member, thereby reducing the risk of deviation in the supporting direction and simplifying the operation process. In addition, since the supporting matching portion protrudes from the outer surface of the movable rod in the second direction, support and limit can be achieved outside the movable rod, reducing the impact on the structural strength of the movable rod, and facilitating observation of whether the support and limit of the movable rod on the fixed assembly are in place, thereby improving the reliability of support and limit.

[0020] In some embodiments, the limiting mechanism further includes a first position detector, which is disposed on the fixed component and is used to detect whether the movable part is in the limiting position.

[0021] By providing a first position detector to detect whether the movable member is in the limit position, some unreliable operations when the movable member is not in the limit position can be reduced, thereby improving the reliability of the limit mechanism.

[0022] In some embodiments, the first position detector is mounted on the support stopper.

[0023] By installing the first position detector on the support limiting member, the installation position of the first position detector is made closer to the limiting position of the movable member, thereby improving the detection accuracy.

[0024] In some embodiments, the support and limiting member has a first accommodating cavity, and the detection end of the first position detector protrudes into the first accommodating cavity.

[0025] By protruding the detection end of the first position detector into the first accommodating cavity, the detection end of the first position detector can be protected, reducing the risk of damage due to external factors, thereby improving the reliability of detection.

[0026] In some embodiments, the first position detector includes a first position proximity switch, and the first position proximity switch is used to detect whether the movable member is in a limit position.

[0027] Since the first position proximity switch can detect whether the movable part is in the limit position in a non-contact manner, the movable part does not press the first position proximity switch when it is in the limit position, thereby increasing the service life of the first position detector.

[0028] In some embodiments, the fixing assembly further includes a supporting member, and the movable member further includes an initial position separated from the limiting position, and when the movable member is in the initial position, the supporting member can support the movable member along the first direction.

[0029] By arranging the support member to support the movable member at the initial position, the position of the movable member relative to the fixed assembly can be determined, the movable member does not separate from the fixed assembly, and the limiting mechanism can always be used as a whole.

[0030] In some embodiments, the movable member can perform translational motion along a first direction and rotational motion in a plane perpendicular to the first direction relative to the fixed assembly;

[0031] The movable part can be switched between the initial position and the limit position through translation movement and rotation movement.

[0032] In this way, through the translational movement of the movable part, the movable part can be moved closer to or away from the cover body, and through the rotational movement of the movable part, the movable part and the supporting limit part can be matched and separated. The combination of the two movements makes it simple to switch the movable part between the initial position and the limit position, and because the movable part needs to be rotated to achieve matching and separation with the supporting limit part, the operator has a stronger sense of operation and can more easily perceive the current state of the movable part.

[0033] In some embodiments, the limiting mechanism further includes a second position detector, which is disposed on the fixed component and is used to detect whether the movable part is in an initial position.

[0034] By providing a second position detector to detect whether the movable member is in the initial position, some unreliable operations when the movable member is not in the initial position can be reduced, thereby improving the reliability of the limiting mechanism.

[0035] In some embodiments, the second position detector is mounted to the support.

[0036] By installing the second position detector on the supporting member, the installation position of the second position detector is made closer to the initial position of the movable member, thereby improving the detection accuracy.

[0037] In some embodiments, the second position detector includes a second position proximity switch, and the second position proximity switch is used to detect whether the movable member is in the initial position.

[0038] Since the second position proximity switch can detect whether the movable part is in the initial position without contact, the movable part does not press the second position proximity switch when it is in the limit position, thereby increasing the service life of the second position proximity switch.

[0039] In some embodiments, the fixing assembly further includes a guide member, and the guide member is used to guide the movement of the movable member.

[0040] By providing the guide member, the accuracy of the movable member moving to the limit position or the initial position can be improved, and the movable operation of the movable member can be simplified.

[0041] In some embodiments, the guide member includes a guide cylinder, and the movable member is inserted into the guide cylinder; and / or

[0042] The guide member comprises a first sub-guide member and a second sub-guide member which are arranged opposite to each other. The first sub-guide member and the second sub-guide member are arranged at a distance from each other to form a guide groove. The movable member is slidably arranged in the guide groove.

[0043] The guide cylinder can be wrapped around the outer side of the movable part in the circumferential direction, so on the one hand, it can play a guiding role, and on the other hand, it can also limit the movable part from deviating in directions other than the guiding direction, thereby improving the accuracy of the guidance. The method of forming the guide groove by arranging the first sub-guide member and the second sub-guide member at intervals from each other is simple, and because the guide groove does not completely wrap around the outer side of the movable part in the circumferential direction, the movable part can have a certain degree of freedom in sliding, thereby reducing the jamming phenomenon during the activity process.

[0044] In a second aspect, the present application further provides a battery feeding device, including a feeding mechanism and a limiting mechanism in any of the above embodiments;

[0045] The feeding mechanism comprises a feeding body with a feeding port, a cover body covered on the feeding port and a cover-opening driving member, wherein the cover-opening driving member can drive the cover body to open the feeding port.

[0046] The above-mentioned feeding device is provided with a fixed component and a movable part through a limiting mechanism, so that the movable part can move to the limited position relative to the fixed component when the cover opening driving part drives the cover body to open the feeding port. Since the supporting limiting part of the fixed component can support the movable part along a first direction when the movable part is in the limited position, and limit the movable part in a second direction intersecting with the first direction, the possibility of the movable part slipping, deflecting and the like in the second direction is reduced, so that the movable part can reliably support the limited cover body along the first direction, thereby improving the reliability of opening the cover.

[0047] In a third aspect, the present application also provides a battery feeding device, including a feeding mechanism and a limiting mechanism;

[0048] The feeding mechanism comprises a feeding body having a feeding port, a cover body covering the feeding port, and a cover-opening driving member, wherein the cover-opening driving member can drive the cover body to open the feeding port;

[0049] The limiting mechanism comprises a fixed component, a movable part, a first position detector and a second position detector, the movable part is movably arranged on the fixed component, the movable part comprises a limiting position for supporting and limiting the cover body along the first direction when the cover body opens the feeding port, the movable part also comprises an initial position for separating from the cover body when the cover body opens the feeding port, and the first position detector and the second position detector are both arranged on the fixed component;

[0050] The fixing assembly includes a support and limiter and a support member; when the movable member is in the limit position, the support and limiter can support the movable member along the first direction and limit the movable member along the second direction; when the movable member is in the initial position, the support member can support the movable member along the first direction; the first direction intersects with the second direction;

[0051] The first position detector is used to detect whether the movable member is in the limit position, and the second position detector is used to detect whether the movable member is in the initial position;

[0052] The controller is communicatively connected with the cover opening driving member, the first position detector and the second position detector.

[0053] The above-mentioned feeding device is provided with a controller which is communicatively connected with the cover opening drive member, the first position detector and the second position detector. By detecting the position information of the movable part of the limit mechanism, a linkage relationship can be established between the action of the cover opening drive member, thereby improving the operating reliability of the feeding device.

[0054] In some embodiments, the feeding device also includes an alarm, and the controller is communicatively connected to the alarm.

[0055] In a fourth aspect, the present application also provides a battery manufacturing system, comprising the feeding device in any of the above embodiments.

[0056] The above-mentioned battery manufacturing system arranges fixed components and movable parts through a limiting mechanism, so that the movable part can move to the limited position relative to the fixed component when the cover opening driving member drives the cover body to open the feeding port. Since the supporting limiting member of the fixed component can support the movable part along a first direction when the movable part is in the limited position, and limit the movable part in a second direction intersecting with the first direction, the possibility of the movable part slipping, deflecting and other abnormalities in the second direction is reduced, so that the movable part can reliably support the limited cover body along the first direction, thereby improving the reliability of opening the cover.

In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0087] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0091] 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.

[0092] At present, most batteries include electrolyte, packaging shell and battery cells obtained by winding or stacking positive electrode sheets, negative electrode sheets and separators separating the positive electrode sheets and negative electrode sheets. Among them, the positive electrode sheets include positive electrode collectors generally made of aluminum foil and positive electrode membranes attached to the positive electrode collectors and containing positive electrode active materials; the negative electrode sheets include negative electrode collectors generally made of copper foil and negative electrode membranes attached to the negative electrode collectors and containing negative electrode active materials.

[0093] When preparing positive electrode membranes and negative electrode membranes, according to the process requirements, a variety of powders and liquids need to be put into a mixer, and after stirring by the mixer, a paste-like slurry with a certain viscosity is obtained. The slurry is then coated on the current collector and formed into a membrane after drying.

[0094] At present, the method of feeding powder into the mixer is to adopt open manual feeding, that is, to open the cover of the barrel containing the powder, or to open the bag mouth of the packaging bag containing the powder, and then pour the powder into the mixer from the feeding port.

[0095] The lid of the barrel containing the powder is opened to pour the powder into the mixer from the feeding port, wherein the lid is opened by lifting the cylinder. Since the pouring of the powder takes a long time, the cylinder needs to be supported between the lid and the barrel for a long time. Therefore, once the cylinder is damaged or returns to its original position in advance, the lid will fall suddenly, which will cause certain harm to people or objects around.

[0096] In order to alleviate the unreliability problem of the cylinder when supporting the cover body, a limiting mechanism is designed, which can support and limit the cover body between the cover body and the barrel body when the cylinder supports the cover body to open the feeding port. Specifically, the limiting mechanism includes a fixed component and a movable part, the fixed component is used to be fixed on the feeding body, the movable part can be movably arranged on the fixed component, and the movable part includes a limiting position for supporting and limiting the cover body when the cover body opens the feeding port, wherein the fixed component includes a support limiting part, and the support limiting part can support and limit the movable part when the movable part is at the limiting position.

[0097] By providing a fixed component and a movable part, the movable part can be moved to a limited position relative to the fixed component when the cover body is opened. Since the supporting and limiting part of the fixed component can support the movable part in a first direction when the movable part is in the limited position and limit it in a second direction intersecting with the first direction, the possibility of the movable part slipping, deflecting and other abnormalities in the second direction is reduced, so that the movable part can reliably support the limited cover body in the first direction, thereby improving the reliability of opening the cover.

[0098] Figure 1 It is a schematic diagram of the structure of a feeding device according to one or more embodiments. Figure 2 It is a schematic diagram of the three-dimensional structure of the limiting mechanism in the initial position according to one or more embodiments. Figure 3 for Figure 2 The schematic diagram of the exploded structure of the limiting mechanism is shown. Figure 4 for Figure 2 The front view of the limit mechanism shown in the limit position. Figure 1~Figure 4 , an embodiment of the present application provides a limiting mechanism 100. The limiting mechanism 100 is used for a feeding device 200, and the feeding device 200 includes a feeding body 220 having a feeding port 210 and a cover body 230 covering the feeding port 210. The limiting mechanism 100 includes a fixed component 10 and a movable part 20. The fixed component 10 is used to be fixed on the feeding body 210. The movable part 20 can be movably arranged on the fixed component 10, and the movable part 20 includes a limiting position for supporting and limiting the cover body 230 along a first direction when the cover body 230 opens the feeding port 210. Among them, the fixed component 10 includes a support limiting part 11, and when the movable part 20 is in the limiting position, the support limiting part 11 can support the movable part 20 along the first direction and limit the movable part 20 along the second direction. The first direction intersects with the second direction.

[0099] The fixing component 10 refers to a component that can be fixedly connected to an external object. The fixing component 10 can be formed by combining multiple components, and the combination method can be connected by means of screws, bolts, etc., or it can be formed by combining multiple components in an integrated manner.

[0100] The movable member 20 is movably disposed on the fixed component 10, which means that the movable member 20 can move relative to the fixed component 10 in the form of telescopic, translational, rotational, etc., or a combination of any two of the telescopic, translational, rotational, etc.

[0101] The limit position refers to a position that can limit the relative movement of the movable member 20 to the fixed component 10. For example, the movable member 20 can move relative to the fixed component 10. Figure 1 However, when in the limit position, the movable member 20 can no longer make a vertical downward translational movement relative to the fixed assembly 10. It should be noted that the limit position can only limit part of the movement of the movable member 20 relative to the fixed assembly 10, or can also limit all the movement of the movable member 20 relative to the fixed assembly 10.

[0102] The support stopper 11 refers to a component that can limit the supported object. The support stopper 11 can support the movable member 20 along the first direction, which means that the support stopper 11 can provide a supporting force to the movable member 20 in the first direction. The direction of the supporting force can be a vertical direction or other directions. The first direction can also be the direction in which the cover body 230 moves relative to the feeding body 220 to open the feeding port 210. Specifically, the first direction is Figure 2 The support and limit member 11 limits the movable member 20 along the second direction, which means that the support and limit member 11 can limit the movement of the movable member 20 in the second direction. Specifically, the second direction is Figure 2 The X and Z directions are shown.

[0103] The limiting mechanism 100 of the embodiment of the present application, by providing a fixed component 10 and a movable part 20, can enable the movable part 20 to move to a limiting position relative to the fixed component 10 when the cover body 230 opens the feeding port 210. Since the supporting limiting part 11 of the fixed component 10 can support the movable part 20 along a first direction when the movable part 20 is in the limiting position, and limit the movable part 20 in a second direction intersecting with the first direction, the possibility of the movable part 20 slipping, deflecting, and the like in the second direction is reduced, so that the movable part 20 can reliably support the limiting cover body along the first direction, thereby improving the reliability of opening the cover.

[0104] See also Figure 4~Figure 6 According to some embodiments of the present application, the support and limit member 11 includes a first support surface 111 and a first limit portion 112 disposed on the first support surface 111, and the movable member 20 has a support matching portion 21. When the movable member 20 is in the limited position, the first support surface 111 can support the support matching portion 21 along the first direction, and the first limit portion 112 cooperates with the support matching portion 21 to limit along the second direction.

[0105] The first supporting surface 111 refers to a surface that can contact with an object to provide a supporting force for the object. Specifically, the first supporting surface 111 can be, but is not limited to, a plane, a curved surface, and the like.

[0106] The first limiting portion 112 refers to a component that can limit the movement of an object.

[0107] The supporting and matching part 21 refers to a part that can be supported and has a matching relationship with other parts. Specifically, the supporting and matching part 21 matches with the supporting and limiting member 11.

[0108] By providing the first support surface 111 to support the support matching portion 21 of the movable member 20, the stability of the support can be improved, and the first limiting portion 112 provided on the first support surface 111 cooperates with the support matching portion 21 to achieve stable limiting in the second direction. In addition, since the first limiting portion 112 is provided on the first support surface 111, the supporting and limiting effects on the support matching portion 21 of the movable member 20 are more concentrated, thereby making the supporting and limiting effects more reliable.

[0109] In other embodiments, the first supporting surface 111 and the first limiting portion 112 may also be separated from each other.

[0110] See also Figure 4~Figure 6 According to some embodiments of the present application, the supporting matching portion 21 has a first matching portion 211. When the movable member 20 is in the limiting position, the first limiting portion 112 is circumferentially matched along the first matching portion 211 to limit along the second direction.

[0111] The circumferential cooperation between the first limiting portion 112 and the first matching portion 211 means that the first limiting portion 112 and the first matching portion 211 have a matching relationship in the circumferential direction. For example, the first limiting portion 112 is a protrusion, and the first matching portion 211 is a groove. The protrusion extends into the interior of the groove, that is, the outer peripheral wall of the protrusion extends into the interior of the groove and is then arranged opposite to the inner peripheral wall of the groove, so that the cooperation in the circumferential direction is achieved.

[0112] It should be pointed out here that the circumferential engagement of the first limiting portion 112 along the first engaging portion 211 may be, but is not limited to, an entire circle engagement along the circumferential direction, and may also be an intermittent engagement along the circumferential direction.

[0113] By setting the supporting matching part 21 of the movable part 20 to have a first matching part 211, and making the first limiting part 112 of the supporting limiting part 11 circumferentially match along the first matching part 211 to limit along the second direction, the abnormality of the movable part 20 being offset relative to the fixed component 10 in any direction other than the first direction at the limiting position can be reduced, thereby improving the limiting reliability of the movable part 20 at the limiting position.

[0114] See also Figure 4~Figure 6According to some embodiments of the present application, one of the first limiting portion 112 and the first matching portion 211 includes a limiting hole 1121 , and the other includes a limiting protrusion 2111 matching with the limiting hole 1121 .

[0115] The limiting hole 1121 refers to a hole that penetrates at least one side wall of the supporting limiting member 11 or the movable member 20 .

[0116] The limiting protrusion 2111 plays a limiting role and forms an arch structure on the supporting limiting member 11 or the movable member 20, and a corresponding recessed structure is formed around the arch structure.

[0117] The circumferential limiting is achieved by providing the limiting hole 1121 and cooperating with the limiting protrusion 2111 , so that the matching mode of the first limiting portion 112 and the first matching portion 211 is simple, thereby making it easier to operate the movable member 20 to limit relative to the fixed component 10 .

[0118] Specifically in the embodiments of the present application, the first limiting portion 112 includes a limiting hole 1121 , and the first matching portion 211 includes a limiting protrusion 2111 .

[0119] In other embodiments, the limiting hole 1121 may also be replaced by, but is not limited to, a recessed structure such as a limiting groove.

[0120] Furthermore, the supporting matching portion 21 also includes a supported surface 212, and the first matching portion 211 is disposed on the supported surface 212. When the movable member 20 is in the limiting position, the supported surface 212 abuts against the first supporting surface 111 along the first direction. Specifically, the first matching portion 211 includes a limiting protrusion 2111 protruding from the supported surface 212.

[0121] See also Figure 6 According to some embodiments of the present application, the movable member 20 further includes a movable rod 22 extending along a first direction, and the supporting mating portion 21 is connected to the movable rod 22 and protrudes from the movable rod 22 along a second direction.

[0122] The movable rod 22 is a movable component in the shape of a slender rod.

[0123] The supporting matching portion 21 protrudes from the movable rod 22 along the second direction, which means that the supporting matching portion 21 protrudes from the outer surface of the movable rod 22 along the second direction.

[0124] By providing the movable rod 22 extending in the first direction, the support matching portion 21 connected thereto can directly reach the limit position supported on the support limiter 11, thereby reducing the risk of deviation in the support direction and simplifying the operation process. In addition, since the support matching portion 21 protrudes from the outer surface of the movable rod 22 in the second direction, support and limit can be achieved outside the movable rod 22, reducing the impact on the structural strength of the movable rod 22, and facilitating observation of whether the support and limit of the movable rod 22 on the fixing assembly 10 are in place, thereby improving the reliability of support and limit.

[0125] See also Figure 2~Figure 4 According to some embodiments of the present application, the limiting mechanism 100 further includes a first position detector 30, which is disposed on the fixing assembly 10 and is used to detect whether the movable member 20 is in the limiting position.

[0126] The first position detector 30 is a device for detecting a position state and can be a photoelectric sensor or a contact switch.

[0127] By providing the first position detector 30 to detect whether the movable member 20 is in the limit position, some unreliable operations when the movable member 20 is not in the limit position can be reduced, thereby improving the reliability of the limit mechanism 100.

[0128] In actual applications, when the cover of the barrel containing powder is lifted and opened by the cylinder, the operator operates the movable part 20 to pre-limit the position, but the movable part 20 is not actually in place. If the movable part 20 is not in the limit position and the powder is poured directly, there is a risk of the cover falling. At this time, the first position detector 30 can be used to detect and feedback whether the movable part 20 is in the limit position. If the movable part 20 is detected to be in the limit position, the powder can be poured. If the movable part 20 is not detected to be in the limit position, check whether the movable part 20 is in place, and then determine whether the powder needs to be poured.

[0129] In addition, when the lid of the barrel containing the powder is closed and locked by the cylinder, if it is detected that the movable part 20 is in the limit position at this time, it is necessary to confirm whether the cylinder return locking is incorrect or whether the movable part 20 is abnormal.

[0130] According to some embodiments of the present application, the first position detector 30 includes a first position proximity switch, and the first position proximity switch is used to detect whether the movable member 20 is in a limit position.

[0131] The first position proximity switch may be an eddy current proximity switch, a capacitive proximity switch, or the like.

[0132] Since the first position proximity switch can detect whether the movable member 20 is in the limit position in a non-contact manner, the movable member 20 does not press the first position proximity switch when it is in the limit position, thereby increasing the service life of the first position detector 30.

[0133] See also Figure 2~Figure 4 According to some embodiments of the present application, the first position detector 30 is installed on the support limiter 11 .

[0134] By installing the first position detector 30 on the support limiter 11 , the installation position of the first position detector 30 is made closer to the limit position of the movable member 20 , thereby improving the accuracy of detection.

[0135] Specifically, the first position detector 30 can be installed on the support and limit member 11 by means of, but not limited to, bolts, buckles, cable ties, clamps, etc.

[0136] See also Figure 4 and Figure 5 According to some embodiments of the present application, the support and limit member 11 has a first accommodating cavity 113 , and the detection end 31 of the first position detector 30 protrudes into the first accommodating cavity 113 .

[0137] By protruding the detection end 31 of the first position detector 30 into the first accommodating cavity 113, the detection end 31 of the first position detector 30 can be protected, reducing the risk of damage due to external factors, thereby improving the reliability of detection.

[0138] Specifically in the embodiment of the present application, the support stopper 11 is a hollow structure with a feeding port on one side, and has a first accommodating cavity 113 connected to the feeding port. The first position detector 30 is installed from the feeding port to the support stopper 11, and is fixed on an end wall of the support stopper 11 along the first direction, and the detection end 31 protrudes into the first accommodating cavity 113, and the first support surface 111 and the first limiting portion 112 are arranged on the other end wall opposite to the first direction. The first position detector 30 can be fixed on the end wall of the support stopper 11 by opening a first through hole 114 on the end wall, and the first position detector 30 passes through the first through hole 114 and is connected to the end wall through the first connecting member 40. The first connecting member 40 can be, but is not limited to, a nut, a buckle, etc.

[0139] Furthermore, in order to make the first position detector 30 more accurately detect whether the movable member 20 is in the limit position, the first position detector 30 is used to detect whether the first matching portion 211 is in the limit position. Specifically, the first position detector 30 is arranged opposite to the first limit portion 112 on the limit support member 11.

[0140] See also Figure 2~Figure 4According to some embodiments of the present application, the fixing assembly 10 further includes a support member 12, and the movable member 20 further includes an initial position separated from the limiting position. When the movable member 20 is in the initial position, the support member 12 can support the movable member 20 along the first direction.

[0141] By arranging the support member 12 to support the movable member 20 at the initial position, the position of the movable member 20 relative to the fixed component 10 can be determined, the movable member 20 does not separate from the fixed component 10, and the limiting mechanism 100 can always be used as a whole.

[0142] It should be pointed out that in the implementation manner of the present application, when the movable member 20 is in the initial position, the movable member 20 cannot support the cover body.

[0143] Specifically, the support member 12 and the support stopper 11 are spaced apart from each other along the first direction. In other embodiments, the support member 12 and the support stopper 11 may also be spaced apart from each other along the second direction.

[0144] Specifically, the support member 12 has a second support surface 121, and the second support surface 121 can support the movable member 20 when it is in the initial position.

[0145] According to some embodiments of the present application, the movable member 20 can perform translational motion along a first direction and rotational motion in a plane perpendicular to the first direction relative to the fixed assembly 10. The movable member 20 can switch between the initial position and the limit position through translational motion and rotational motion.

[0146] Specifically, when the movable member 20 moves from the initial position to the limit position, the movable member 20 translates along the first direction, and then rotates to the limit position where its support matching portion 21 cooperates with the support limit member 11. When the movable member 20 moves from the limit position to the initial position, it first rotates so that its support matching portion 21 is separated from the support limit member 11, and then translates along the first direction to the initial position that cooperates with the support member 12.

[0147] In this way, through the translational movement of the movable part 20, the movable part 20 can be moved closer to or away from the cover body, and through the rotational movement of the movable part 20, the movable part 20 can be matched with and separated from the support limit part 11. The combination of the two movements makes it simple to switch the movable part 20 between the initial position and the limit position. Since the movable part 20 needs to be rotated to achieve the matching and separation with the support limit part 11, the operator has a stronger sense of operation and can more easily perceive the current state of the movable part 20.

[0148] In other embodiments, the movable part 20 can only make a translational movement along the first direction, while the support and limit member 11 can make a rotational movement relative to the movable part 20 in a plane perpendicular to the first direction. Therefore, the support and limit member 11 can be matched with and separated from the movable part 20 through the rotational movement of the support and limit member 11.

[0149] See also Figure 2~Figure 4 According to some embodiments of the present application, the limiting mechanism 100 further includes a second position detector 50, which is disposed on the fixing assembly 10 and is used to detect whether the movable member 20 is in an initial position.

[0150] The second position detector 50 is a device for detecting a position state and can be a photoelectric sensor or a contact switch.

[0151] By providing the second position detector 50 to detect whether the movable member 20 is in the initial position, some unreliable operations when the movable member 20 is not in the initial position can be reduced, thereby improving the reliability of the limiting mechanism 100.

[0152] In actual applications, when the lid of the barrel containing powder needs to be closed, the operator operates the movable part 20 to pre-initial position, but the movable part 20 is not actually in place. If it is not in the initial position and the cylinder is directly operated to return, there is a risk of the lid falling and damaging the movable part 20. At this time, the second position detector 50 can be used to detect and feedback whether the movable part 20 is in the initial position. If the movable part 20 is detected to be in the initial position, the cylinder can be operated to return and the lid can be closed. If it is not detected to be in the initial position, check whether the movable part 20 is in place, and then determine whether it needs to be operated to return.

[0153] In addition, when the lid of the barrel containing the powder is closed and locked by the cylinder, if the second position detector 50 detects that the movable part 20 is not in the initial position, it is necessary to confirm whether the second position detector 50 has an abnormality or is artificially shielded.

[0154] According to some embodiments of the present application, the second position detector includes a second position proximity switch, and the second position proximity switch is used to detect whether the movable member 20 is in the initial position.

[0155] The second position proximity switch may be an eddy current proximity switch, a capacitive proximity switch, or the like.

[0156] Since the second position proximity switch can detect whether the movable member 20 is in the initial position without contact, the movable member 20 does not press the second position proximity switch when it is in the limit position, thereby increasing the service life of the second position proximity switch.

[0157] See also Figure 2 and Figure 7 According to some embodiments of the present application, the second position detector 50 is mounted on the support member 12 .

[0158] By installing the second position detector 50 on the support member 12, the installation position of the second position detector 50 is made closer to the initial position of the movable member 20, thereby improving the accuracy of detection.

[0159] Specifically, the second position detector 50 can be installed on the support member 12 by means of, but not limited to, bolts, buckles, cable ties, clamps, etc.

[0160] Specifically in the embodiment of the present application, the support member 12 includes two end walls arranged opposite to each other along the first direction, the second position detector 50 is fixed on one of the end walls, and the movable member 20 can be in contact with the other end wall opposite to be supported on the support member 12 when in the initial position. The second position detector 50 can be fixed on the end wall of the support member 12 by opening a second through hole 122 on the end wall, the second position detector 50 passes through the second through hole 122, and is connected to the end wall through a second connecting member 60. The second connecting member 60 can be, but is not limited to, a nut, a buckle, etc.

[0161] It should be pointed out that in the embodiment of the present application, when the movable member 20 is in the initial position, only the support member 12 is used to support it without limiting the position, so the second position detector 50 can directly detect whether the support matching portion 21 is in place, without the need to accurately detect whether the first matching portion 211 on the support matching portion 21 is in place. Therefore, the structure of the support member 12 is simpler than that of the support limiting member 11.

[0162] See also Figure 2~Figure 4 According to some embodiments of the present application, the fixing assembly 10 further includes a guide member 13, and the guide member 13 is used to guide the movement of the movable member 20.

[0163] The guide member 13 refers to a component that guides the movement of an object.

[0164] By providing the guide member 13, the accuracy of the movable member 20 moving to the limit position or the initial position can be improved, and the moving operation of the movable member 20 can be simplified.

[0165] See also Figure 2~Figure 4 According to some embodiments of the present application, the guide member 13 includes a guide cylinder 131 , and the movable member 20 is inserted into the guide cylinder 131 .

[0166] The guide cylinder 131 can be circumferentially wrapped around the outer side of the movable part 20 , so that on one hand, it can play a guiding role, and on the other hand, it can also limit the movable part 20 from deviating in directions other than the guiding direction, thereby improving the accuracy of the guidance.

[0167] See also Figure 2~Figure 4 In other embodiments, the guide member 13 includes a first sub-guide member 132 and a second sub-guide member 133 that are arranged opposite to each other. The first sub-guide member 132 and the second sub-guide member 133 are spaced apart from each other to form a guide groove 134, and the movable member 20 is slidably arranged in the guide groove 134.

[0168] The method of forming the guide groove 134 by spacing the first sub-guide member 132 and the second sub-guide member 133 from each other is simple, and since the guide groove is not completely circumferentially covered on the outside of the movable member 20, the movable member 20 can have a certain degree of freedom in sliding, thereby reducing the jamming phenomenon during the movement.

[0169] In other embodiments, the guide member 13 includes a guide cylinder 131, a first sub-guide member 132 and a second sub-guide member 133. In this way, the accuracy of the guidance is improved and the jamming phenomenon during the activity is reduced.

[0170] Specifically, the first sub-guide member 132 and the second sub-guide member 133 are arranged at intervals from each other along the second direction, and the guide cylinder 131 is arranged at one end of the first sub-guide member 132 and the second sub-guide member 133 along the first direction. In the specific embodiment of the present application, the guide cylinder 131 is arranged closer to the support limiter 11 than the support member 12. On the one hand, the limit position is closer to the cover body supported by the movable member 20, so a certain structural strength support can be provided for the movable member 20. On the other hand, since the guide cylinder 131 can also limit the movable member 20 circumferentially, it can form a superimposed effect with the support and limiting effect of the support limiter 11 on the movable member 20, and further improve the limiting reliability of the limiting mechanism 100 at the limiting position.

[0171] See also Figure 2~Figure 4 According to some embodiments of the present application, the fixing assembly 10 further includes a fixing base plate 14 , and the limiting support member 11 , the support member 12 and the guide member 13 are all installed on one side of the fixing base plate 14 .

[0172] The fixed base plate 14 can form a fixed connection relationship with the external components, so that the limiting support member 11, the support member 12 and the guide member 13 thereon can all be fixed, thereby providing a reliable support and limiting effect for the movable member 20.

[0173] According to some embodiments of the present application, see Figure 1 to Figure 7Some embodiments of the present application provide a limiting mechanism 100. The limiting mechanism 100 includes a fixed assembly 10, a movable member 20, a first position detector 30, and a second position detector 50. The fixed assembly 10 includes a fixed base plate 14 and a support limiting member 11, a support member 12, and a guide member 13 fixed on a surface of one side of the fixed base plate 14. The guide member 13 extends along a first direction, the support limiting member 11 is arranged on one side of the guide member 13, and the support member 12 is arranged at one end of the guide member 13, and is spaced from the support limiting member 11 along the first direction. The movable member 20 can perform translational motion along the first direction and rotational motion in a plane perpendicular to the first direction relative to the fixed assembly 10. The movable member 20 can switch between an initial position and a limiting position through translational motion and rotational motion. The movable member 20 includes a support matching portion 21 and a movable rod 22 extending along the first direction. The support matching portion 21 is connected to the movable rod 22 and protrudes from the movable rod 22 along the second direction. The movable rod 22 can cooperate with the guide member 13 to guide the movable member 20 to perform translational movement along the first direction. When the movable member 20 is in the initial position, the support member 12 can support the support matching portion 21 along the first direction, and when the movable member 20 is in the limit position, the support limit member 11 can support the support matching portion 21 along the first direction and limit the support matching portion 21 along the second direction. The first direction is perpendicular to the second direction. The support limit member 11 includes a limit hole 1121, and the support matching portion 21 includes a limit protrusion 2111 that cooperates with 1121, so that when the movable member 20 is in the limit position, the support limit member 11 limits the support matching portion 21 along the second direction. The first position detector 30 is arranged on the support limit member 11, and is used to detect whether the movable member 20 is in the limit position, and the second position detector 50 is arranged on the support member 12, and is used to detect whether the movable member 20 is in the initial position.

[0174] Also, see Figure 1~Figure 4 The present application further provides a feeding device 200, comprising a feeding mechanism and the limiting mechanism 100 in any of the above embodiments. The feeding mechanism comprises a feeding body 220 having a feeding port 210, a cover 230 covering the feeding port 210, and a cover opening drive 240, which can drive the cover 230 to open the feeding port 210.

[0175] The feeding mechanism refers to a mechanism that can receive and transport the fed material. The feeding mechanism can be barrel-shaped or inverted cone-shaped. Specifically, the fed material can be powder, granules, or slurry.

[0176] The feeding body 220 refers to the main body of the feeding mechanism that can receive and transport the fed materials. Usually, the top of the feeding body 220 has a feeding port 210, and the fed materials can enter the feeding cavity in the feeding body 220 from the feeding port 210.

[0177] The cover body 230 is disposed at the feeding port 210 to prevent the fed materials from leaking out from the feeding port 210 and to prevent other foreign materials from entering the feeding chamber from the feeding port 210 when the feeding mechanism is not needed.

[0178] The cover opening drive 240 refers to a mechanism that can drive the cover body 230 to open the feeding port 210. Specifically, the cover opening drive 240 may include, but is not limited to, a cylinder, a hydraulic cylinder, etc. The output end of the cover opening drive 240 may be connected to the cover body 230, or may not be connected, and only forms a contact relationship with the cover body 230 when the cover body 230 needs to be opened.

[0179] The feeding device 200 of the embodiment of the present application is provided with a fixed component 10 and a movable part 20 through a limiting mechanism 100, so that the movable part 20 can move to the limited position relative to the fixed component 10 when the cover opening drive member 240 drives the cover body 230 to open the feeding port 210. Since the support limiting member 11 of the fixed component 10 can support the movable part 20 along a first direction when the movable part 20 is in the limited position, and limit the movable part 20 in a second direction intersecting with the first direction, the slippage, deviation and other abnormalities of the movable part 20 in the second direction are reduced, so that the movable part 20 can reliably support the limited cover body 230 along the first direction, thereby improving the reliability of opening the cover.

[0180] See also Figure 2~Figure 4 and Figure 8The present application also provides a feeding device 200, including a feeding mechanism, a limiting mechanism 100 and a controller 250. The feeding mechanism includes a feeding body 220 having a feeding port 210, a cover 230 covering the feeding port 210 and a cover opening drive 240, and the cover opening drive 240 can drive the cover 231 to open the feeding port 210. The limiting mechanism 100 includes a fixed component 10, a movable component 20, a first position detector 30 and a second position detector 50. The movable component 20 can be movably arranged on the fixed component 10, and the movable component 20 includes a limiting position for supporting and limiting the cover 230 when the cover 230 opens the feeding port 210, and the movable component 20 also includes an initial position for separating from the cover 230 when the cover 230 opens the feeding port 210. The first position detector 30 and the second position detector 50 are both arranged on the fixed component 10. Among them, the fixed component 10 includes a support limiting component 11 and a support component 12. When the movable member 20 is in the limit position, the support limit member 11 can support the movable member 20 along the first direction and limit the movable member 20 along the second direction. When the movable member 20 is in the initial position, the support member 12 can support the movable member 20 along the first direction. The first direction intersects with the second direction. The first position detector 30 is used to detect whether the movable member 20 is in the limit position, and the second position detector 50 is used to detect whether the movable member 20 is in the initial position. The controller 250 is connected to the cover opening drive member, the first position detector 30 and the second position detector 50 for communication.

[0181] It should be noted that the specific structure of the limiting mechanism 100 is the same as the specific structure of the limiting mechanism 100 in any of the aforementioned embodiments, and will not be described in detail herein.

[0182] The controller 250 is communicatively connected with the cover opening drive member 240, the first position detector 30 and the second position detector 50, which means that the position information of the movable member 20 detected by the first position detector 30 and the second position detector 50, and the driving information of the cover opening drive member 240 can be sent to the controller 250, and the controller 250 makes corresponding control according to the received information.

[0183] For example, when the first position detector 30 detects that the movable member 20 is at the limit position, the position information of the movable member 20 can be sent to the controller 250, and the controller 250 can send a prohibition return instruction to the cover opening drive member 240 according to the position information of the movable member 20. The cover opening drive member 240 will respond to the prohibition return instruction and cannot return. In this way, it can be ensured that when the movable member 20 is at the limit position, the cover body 230 remains in the open state lifted by the cover opening drive member 240.

[0184] In addition, when the controller 250 obtains that the cover-opening driving member 240 is in the return position, if the first position detector 30 simultaneously obtains information that the movable member 20 is in the limit position, an alarm message is sent. In this case, it is necessary to remind the operator that the cylinder return lock is incorrect or the movable member 20 is abnormal. When the controller 250 obtains that the cover-opening driving member 240 is in the return position, if the second position detector 30 cannot simultaneously obtain information that the movable member 20 is in the initial position, an alarm message is also sent. In this way, the operator can be reminded that the second position detector 50 is abnormal or the second position detector 50 is manually shielded. It should be pointed out here that when the controller 250 obtains that the cover-opening driving member 240 is in the return position, it indicates that the operator has completed the feeding action, the cover body 230 closes the feeding port 210, and the subsequent processing process such as stirring can be entered. If the position information of the movable member 20 is not detected at this time, and the subsequent processing process such as stirring is directly entered, there is a risk of leakage of the fed material from the feeding port 210. Therefore, the movable member 20 is likely to still support the cover body 230 in a limited position, that is, the cover body 230 opens the feeding port 210. Therefore, by adding information that the movable member 20 is in the initial position at the same time, the leakage of the feeding port 210 can be reduced.

[0185] Therefore, in general, the feeding device 200 of the embodiment of the present application is provided with a controller 250 which is communicatively connected with the cover opening drive member 240, the first position detector 30 and the second position detector 50. By detecting the position information of the movable part 20 of the limiting mechanism 100, a linkage relationship can be established between the action of the cover opening drive member 240, thereby improving the operating reliability of the feeding device 200.

[0186] According to some embodiments of the present application, the feeding device 200 further includes an alarm, which is communicatively connected to the controller 250 .

[0187] Since the alarm is communicatively connected to the controller 250, the alarm can respond to the alarm information of the controller 250 to give an alarm, thereby reminding the operator to pay attention to abnormal conditions, thereby improving the operational reliability of the feeding device.

[0188] Optionally, the alarm includes but is not limited to a sound alarm, a light alarm, an audible and visual alarm, etc.

[0189] In some other embodiments, the controller 250 can also send alarm information to a terminal, such as a PC or a mobile phone, to remind the operator.

[0190] In addition, an embodiment of the present application further provides a battery manufacturing system, comprising the feeding device 200 in any of the above embodiments.

[0191] By setting the fixed component 10 and the movable part 20 through the limiting mechanism 100, the movable part 20 can be moved to the limited position relative to the fixed component 10 when the cover opening drive member 240 drives the cover body 230 to open the feeding port 210. Since the support limiting member 11 of the fixed component 10 can support the movable part 20 along the first direction when the movable part 20 is in the limited position, and limit the movable part 20 in the second direction intersecting with the first direction, the slippage, deviation and other abnormalities of the movable part 20 in the second direction are reduced, so that the movable part 20 can reliably support the limited cover body 230 along the first direction, thereby improving the reliability of opening the cover.

[0192] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions that fall within the scope of the claims.
